Problems solved by technology
The existing ordinary bearing press-in device cannot locate the opening and closing cam and the one-way bearing, and cannot meet the assembly requirements of the opening and closing cam and the one-way bearing of the computerized flat knitting machine
However, manual assembly of the opening and closing cams and one-way bearings not only wastes a lot of manpower and material resources, but also increases the manufacturing cost of the computerized flat knitting machine. The damage of components reduces the service life of the opening and closing cam assembly, thereby burying hidden troubles, affecting the operation safety of computerized flat knitting machines, and causing huge losses to customers

The invention discloses an opening and closing cam bidirectional bearing press-in device for a flat knitting machine. The device comprises a support post, a heightening seat, a limiting seat, a guide shaft, a press head, a hydraulic device and an oil tank base; the support post and the heightening seat are mounted on the oil tank base; the limiting seat is provided with a cam limiting hole internally provided with a cam positioning pin; a guide shaft limiting hole is formed in the side face of the limiting seat, and is internally provided with a guide shaft limiting pin; a limiting slot is formed below the body of the guide shaft, and is matched with the guide shaft limiting pin on the limiting seat; a bidirectional bearing positioning pin is arranged above the body of the guide shaft; the hydraulic device is mounted above the support post; and the press head is arranged at the lower end of the hydraulic device and positioned above the guide shaft. The opening and closing cam bidirectional bearing press-in device for the flat knitting machine is simple in structure and simple and convenient to operate and meets the operation demands of a computer flat knitting machine, thus reducing the manufacturing cost of the computer flat knitting machine, eliminating the quality hidden danger of a cam assembly and ensuring the safe operation of the flat knitting machine.
Description
technical field [0001] The invention belongs to the technical field of knitting machines, in particular to a one-way bearing press-in device for an opening and closing cam of a flat knitting machine. Background technique [0002] The opening and closing cam used in the computerized flat knitting machine needs to install a one-way bearing to realize its opening and closing function. When the opening and closing cam is working, in order to prevent the one-way bearing and the opening and closing cam from slipping in the radial direction, a limit groove is opened on the outer edge of the one-way bearing, and a threaded through hole is added on the opening and closing cam. The relative displacement of the two in the radial direction is prevented by clamping the tightening bolts into the limiting groove of the one-way bearing. When the opening and closing cam is assembled with the one-way bearing, the threaded hole on the opening and closing cam should be able to face the limit g...
