Abstract:
All equipments for successive various processes for works are divided into a plurality of blocks to form production lines in which equipments in each production line are coupled with conveyers. These production lines are coupled to an automatic depot with a carriage system. This keeps the rate of operation of production lines high, so that useless increase in cost for equipments can be prevented. Moreover, this production system allows a production line or an equipment to be easily added in accordance with variation in the production rate or the type of products.
Abstract:
A machine tool center (10) displays at least one machine tool (11, 12, 13) which has a working area (17) accessible through an operator door (16) to process workpieces (21). Furthermore, a loading/unloading station (14) for the workpieces (21) and a loading device (22) which transports the workpieces (21) between the loading/unloading station (14) and the respective machine tool (11, 12, 13) and changes these at the machine tool (11, 12, 13) are also provided. In the new machine tool center (10) the loading device (22) is arranged below the working space (17) of the machine tool (11, 12, 13) (FIG. 1).
Abstract:
The invention relates to a process for production of workpieces (1), especially motor vehicle drive assemblies, on a production line, the workpiece (1) having lateral surfaces (3, 11, 12, 18, 21) extending more or less parallel to a longitudinal axis (4) and also frontal areas (7, 8) extending more or less perpendicular to these surfaces and being pivotable and immobilizable in a number of machining positions for the individual machining steps.For the purpose of machining the lateral surfaces (3, 11, 12, 18, 21) and partial areas (2, 5, 6, 20) of the workpiece (1) accessible from them, the workpiece (1) is moved to the individual production stations with its longitudinal axis (4) vertically directed, at the individual production station is pivoted about the longitudinal axis (4) into the machining position required, and is immobilized and clamped in this position.Application of the process claimed for the invention is made possible by the fact that the workpiece (1) is outfitted with a special adjusting element (adjusting holes 9 in the outer circumference of a frontal surface 8 and in a circular line with the longitudinal axis 4 as center).The production process claimed for the invention yields low cost accompanied by maximum production flexibility and is at the same time suitable for high-output mass production (FIG. 1).
Abstract:
A monocrystal ingot conveying/surface grinding apparatus has a plurality of surface grinding devices 221A to 225A disposed serially, a rail 16A disposed adjacent to the ceiling along the devices, a conveying/attitude-adjusting device 20A guided by the rail 16A and having an X-Y-.theta.-.phi. stage 24 and conveyers 14 and 23 disposed below an end portion of the rail 16A and arranged to convey monocrystal ingots 10 before they are ground. The attitude of the monocrystal ingot 10 is adjusted so as to make the grinding rotation center of the monocrystal ingot 10 coincide with the center of each of clamp rotational shafts 70A and 70B of each of the surface grinding devices 221A to 225A. Furthermore, the surfaces of the monocrystal ingots 10 are ground to form cylindrical shapes by the surface grinding devices 221A to 225A, the monocrystal ingots 10 being conveyed by the conveying/attitude-adjusting device 20A and the conveyers 14 and 23. Endoscopes 82A and 82B are inserted into through holes 79A and 79B formed in the shaft core portions of the rotational clamp shafts so that the two end surfaces of the monocrystal ingot 10 are imaged by cameras 84A and 84B.
Abstract:
A workpiece machining system for simultaneously machining the opposite surfaces of workpieces such as discs for disc brakes includes at least two machining apparatus disposed on a workpiece transfer path between a first workpiece inlet conveyor line and a second workpiece outlet conveyor line, for machining respective workpieces while holding and rotating the workpieces in the same attitude as that in which they are conveyed along the first and second conveyor lines. The workpiece machining system also includes a transfer apparatus for transferring the workpieces from the first conveyor line through the machining apparatus to the second conveyor line while maintaining the workpieces in the same attitude.
Abstract:
A semi-automated plant for threading pipe, including oil and gas well casing and tubing, is disclosed. A particular sequencing of equipment activation and movement is utilized in order to have normal operations of the plant, from loading of unthreaded pipe to the unloading of pipe having threads on each end, and a coupling applied to at least one of the ends, performed without requiring manual handling of the pipe. One particularly important portion of the apparatus in the plant is the lifting device for raising the pipe to the height which is proper for the threading machine, or lathe, and a clamping device for clamping the pipe during the threading operation. By use of the disclosed apparatus, the pipe is accurately raised to the proper height, and pipe over a considerable range of size can be securely clamped during the threading operation.
Abstract:
The disclosure describes a multiple drilling machine for simultaneously drilling bores into at least two wooden boards sequentially fed along a single transfer line, said machine comprising at least an upstream and a downstream drilling unit, each capable of processing a board, arranged so that individual boards are carried and set in either unit for simultaneous progressing thereof at an upstream and respectively at a downstream station along said line, the disclosure describing also the manner for operating said multiple machine.
