Abstract

The utility model relates to the technical field of textile machinery, in particular to a cam replacement device for a cam shedding mechanism. The cam replacement device comprises a cam shedding box body, wherein a shaft system comprising a cam shaft, a bearing, a spacer sleeve, a cam assembly, a compress ring, a bolt, a bearing support and a needle bearing is mounted on the cam shedding box; a plurality of cams are mounted on a cam shaft sleeve simultaneously and taken as the assembly; the cam assembly can be integrally mounted on the cam shaft or disassembled when the cam shedding mechanism is in a balanced state; the cam assembly can be assembled and disassembled separately outside the cam box body; type replacement can be completed very conveniently; the matching bore diameter of the bearing support mounted on the box body and the box body is larger than the outer diameters of the cams; after the bearing support is disassembled, the whole cam assembly can be integrally assembled or disassembled flexibly; an operator can assemble the to-be-replaced cam assembly in advance, and then batch replacement can be completed, so that the work efficiency is greatly improved and the work intensity is reduced.

Description

A kind of cam of cam shedding mechanism is changing device more

Technical field

The utility model relates to technical field of textile machine, and the cam that refers in particular to a kind of cam shedding mechanism is changing device more.

Background technology

Cam shedding mechanism is a kind of executing agency that completes the heald frame harness motion in the loom weaving process, the mechanical drive principle of existing cam shedding mechanism is roughly the same, and the cam of cam shedding mechanism replacing (cloth cover variety renovation) is a quite loaded down with trivial details job always, workload is large, need operating personnel to there is the complete all cams of the piecemeal replacing of very large patience, if operate miss needs again again to change, therefore increase the production cost of enterprise, affected the production efficiency of enterprise simultaneously.

Therefore, for the deficiency that overcomes above-mentioned technology, design a simple in structure, easy to use, operating personnel can be quick, completes easily the replacing of cam, enhances productivity, the cam of a kind of cam shedding mechanism of reduction enterprise production cost is changing device more, the problem that the inventor faces just.

The utility model content

For the deficiencies in the prior art, the cam that the purpose of this utility model is to provide a kind of cam shedding mechanism is changing device more, it is simple in structure, easy to use, but operating personnel can be quick, complete easily the replacing of cam, enhance productivity, reduce enterprise's production cost, extraordinary practical and popularizing value is arranged.

For achieving the above object, the utility model adopts following technical scheme:

A kind of cam of cam shedding mechanism is changing device more, described cam more changing device comprises cam shedding casing, camshaft, deep groove ball bearing, spacer, cam sleeve, pin, shedding cam, compact heap, housing screw, bearing block, needle bearing, screw, described cam fast replacing device is that some cams are contained on cam sleeve as an assembly simultaneously, cam shedding mechanism in flat combine under state can be by the cam pack integral installation on camshaft or dismounting.

In a specific embodiment of the present utility model, the cam of described cam shedding casing is changing device more, it is characterized in that by camshaft, and bearing, spacer, the cam pack compacting ring, screw, the axle system that bearing block and needle bearing form is arranged on cam box.

In another specific embodiment of the present utility model, the cam of described cam shedding casing is changing device more, it is characterized in that by cam sleeve, and oval pin, some cams form a cam pack, and this cam pack can be assembled separately and dismantle.

In another specific embodiment of the present utility model, the cam of described cam shedding casing is changing device more, it is characterized in that bearing block, and a needle bearing inside is housed, and bearing block is arranged on the opening casing by six screws.The aperture that bearing block and cam box coordinate is greater than the external diameter of cam.

The utility model is compared and is had obvious advantage and beneficial effect in prior art, and particularly, the beneficial effects of the utility model are as shown from the above technical solution:

1, the technical scheme that the utility model provides is due to can be the cam box outside independent assembly and disassembly of the cam pack of design, can complete very easily the replacing of kind, and the bearing block be arranged on casing is greater than the external diameter of cam with the aperture that coordinates of casing, so after bearing block is removed, can very easily a whole set of cam pack be loaded onto or remove, the operative employee can assemble the cam pack that will change in advance, then replacing in batch, this has greatly improved operating efficiency and has reduced working strength.

The accompanying drawing explanation

Fig. 1 is example structure figure of the present utility model.

Fig. 2 is application examples schematic diagram of the present utility model.

Fig. 3 is cam pack module diagram of the present utility model.

Accompanying drawing explanation: 1-cam shedding casing; The 2-camshaft; The 3-bearing; The 4-spacer; The 5-cam pack; The 51-cam sleeve; The oval pin of 52-; The 53-cam; The 6-compacting ring; The 7-screw; The 8-bearing block; The 9-plastic closure; The 10-needle bearing; 11-screw two; The 12-O RunddichtringO; 13-hole back-up ring.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model, should be understood that these embodiment only are not used in restriction scope of the present utility model for the utility model is described.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values drop on application appended claims limited range equally.

As shown in figure mono-, cam shedding mechanism comprises a casing, power shaft is by bevel-gear sett driving cam axle, shedding cam is contained on camshaft, blade is contained on blade shaft, a whole set of set of blades is arranged on casing, and camshaft (cam) rotarilys actuate blade and swings, and this is the structure of whole cam opening device.

The content of describing in the above due to the applicant is known free prior art, does not therefore remake more detailed repeating, and for a kind of substitute mode of cam more simply and easily is provided, so the applicant has recommended new cam pack structure.

As shown in Figure 2, a kind of cam of cam shedding casing is changing device more, described cam more changing device comprises a cam shedding casing 1, camshaft 2 is by a deep groove ball bearing 3, back-up ring 13 and bearing block 8 and needle bearing 10 for hole, cam pack 5, spacer 4, compacting ring 6 forms an axle system, be arranged on cam shedding casing 1, spacer 4, cam pack 5 and compacting ring 6 are arranged on camshaft 2 by four screws 7, and compacting ring 6 is simultaneously as the bearing cone of needle bearing 10 and play a supporting role.

See figure bis-, a needle bearing 10 is housed in bearing block 8, bearing block 8 is arranged on cam shedding casing 1 by six screws 2 11, and its aperture of matching with cam shedding casing 1 is greater than the external diameter of cam 53.

See again figure tri-, cam pack 5 is comprised of cam sleeve 51, oval pin 52, several cams 53, can be used as independent module installation and removal.

See figure bis-, at cam shedding mechanism, in flat, combine under state, remove plastic closure 9, unscrew four screws 7, then back out six screws 2 11, remove bearing block 8, back out four screws 7, remove compacting ring 6, just a whole set of cam pack 5 can be taken out from the macropore of cam shedding casing 1, ready another group cam pack 5, by above step reverse operating, is completed to more changing jobs of cam.

The applicant is having this design configurations on cam shedding mechanism, through testing, greatly increases work efficiency, and has reduced working strength simultaneously, so the technical scheme that the utility model provides is very practical and efficient beyond doubt.
