Abstract
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
The invention belongs to technical field of knitting machinery, particularly the folding cam unilateral bearing press-in device of flat machine.
Background technology
The folding cam that computer flat knitting machine uses, needs to install unilateral bearing to realize its folding function.And folding cam operationally, skid diametrically to prevent unilateral bearing and folding cam, so, unilateral bearing outer rim has opened stopper slot, folding cam adds tapped through hole, snap in the mode in unilateral bearing stopper slot by puller bolt between the two, stop both diametrically relative displacement to occur.When folding cam and unilateral bearing are assembled, the screwed hole on folding cam is wanted can just to the stopper slot on unilateral bearing.Existing plain bearing press-in device, cannot position folding cam and unilateral bearing, cannot meet the assembling requirement of computer flat knitting machine folding cam and unilateral bearing.And use mode manually to carry out the assembling of folding cam and unilateral bearing, not only waste a large amount of manpower and materials, improve the manufacturing cost of computer flat knitting machine, and pass through this rough original assembling mode manually, often cause the damage of parts, reduce the service life of folding cam pack, thus bury potential faults, affect the security of operation of computer flat knitting machine, bring about great losses to client.
Summary of the invention
The object of the invention is in order to provide a kind of can to the folding cam unilateral bearing press-in device of the flat machine that folding cam and unilateral bearing position.
For this reason, technical scheme of the present invention is: the folding cam unilateral bearing press-in device of flat machine, is characterized in that: it comprises support column, padded seat, limit base, the axis of guide, pressure head, hydraulic means and oil tank base support; Described support column and padded seat are arranged on oil tank base support; Described limit base is fixed on padded seat; In the middle of described limit base, there is axis hole, there is around described axis hole cam limit hole, in cam limit hole, be provided with folding cam orientation pin; Described limit base side has axis of guide spacing hole, is provided with axis of guide spacer pin in axis of guide spacing hole; In the axis hole of described limit base, there is spring; The described axis of guide is arranged in the axis hole of limit base, is positioned at above spring; Have stopper slot below the axis body of the described axis of guide, match with the axis of guide spacer pin on limit base; Unilateral bearing alignment pin is provided with above the axis body of the described axis of guide; Described hydraulic means is arranged on above support column; Described pressure head is arranged on hydraulic means lower end, is positioned at above the axis of guide.
When the present invention works, be enclosed within outside the axis body of the axis of guide by folding cam, bottom surface and limit base upper surface are developed, by the arc top of weld access hole on the folding cam wing, with folding cam orientation pin naturally by jail; Again unilateral bearing is enclosed within axis of guide upper end, on unilateral bearing inner ring, fluting aims at unilateral bearing alignment pin, and bearing lower surface and axis of guide step surface develop; After primer fluid pressure device, folding cam and unilateral bearing are press-fit into place by pressure head; After pressure head retraction, take out the folding cam pack machined.Unilateral bearing supporting for flat machine folding cam can efficiently, accurately be press-fit into place by the present invention.It can carry out supporting location to folding cam and unilateral bearing, assembly one-shot forming simultaneously.Structure of the present invention is simple, simple operation, meets the service requirement of computer flat knitting machine, reduces the manufacturing cost of computer flat knitting machine, eliminate the hidden danger of quality of folding cam pack, ensure that the security of operation of straight-bar machines.
