Abstract
The utility model discloses a disassembling tool of a vacuum pump seal shaft sleeve. The disassembling tool of the vacuum pump seal shaft sleeve comprises a clamping ring. Four threaded holes are formed in the clamping ring in the peripheral direction, jackscrews are arranged in the vertically-symmetric threaded holes, a fixing sheet is fixedly connected with the end, located in the clamping ring, of each jackscrew, a locating head is fixed to the other end, located outside the clamping ring, of each jackscrew, force-adding assembles are arranged in the laterally-symmetric threaded holes, each force-adding assembly comprises a first force-adding rod and a second force-adding rod, one end of each first force-adding rod is connected with one threaded hole in a threaded mode, and each first force-adding rod is detachably connected with one second force-adding rod. According to the disassembling tool of the vacuum pump seal shaft sleeve, a vacuum shaft is fixed to the shaft sleeve through the jackscrews evenly distributed in the periphery of the clamping ring, force-receiving is even, deformation of the shaft sleeve is avoided, damage, caused by improper disassembly, to the machine seal shaft sleeve is avoided, economic loss is reduced, and the repair efficiency is improved. The disassembling tool of the vacuum pump seal shaft sleeve is convenient to use, low in machining cost and capable of effectively reducing the repairing workload and being popularized to the disassembly work of the machine seal shaft sleeve of structures such as a high-speed pump.
Description
Technical field
The utility model relates to a kind of machinery instrument, relates in particular to a kind of vacuum pump envelope shaft sleeve withdrawal tool.
Background technique
The axle sleeve of vacuum pump and pump shaft adopt interference to join and close, once because the impurity such as incrustation scale block or the axle sleeve distortion is difficult to take off, will have certain external force when dismounting could disassemble axle sleeve smoothly from pump shaft.In the reality dismounting, usually adopt copper rod and hammer that it is slowly pounded out.Adopt this form dismounting not only safety and the performance of equipment own all to be existed to unfavorable factor, and because axle sleeve itself is very thin, the axle sleeve smooth surface is without the position of clamping or card, during dismounting, the position of rod iron is difficult to fixing, be easy to knock on hand in the process of knocking, be easy to cause the security incident such as hand is injured in upkeep operation.Secondly because dismounting is to adopt hammering, the conference of exerting oneself damages neck bush, exerts oneself too small very difficult by its dismounting again, is easy to cause the axle sleeve breakage or destroys proud cooperation.
Summary of the invention
The problem existed for above-mentioned prior art, the utility model provides a kind of vacuum pump envelope shaft sleeve withdrawal tool.
To achieve these goals, the technical solution adopted in the utility model is: a kind of vacuum pump envelope shaft sleeve withdrawal tool, comprise snap ring, along the circumferential direction be processed with 4 screws on snap ring, be provided with jackscrew in laterally zygomorphic screw, the end that jackscrew is positioned at snap ring inside is fixedly connected with fixed plate, the other end that is positioned at the snap ring outside is fixed with positioning head, be provided with afterburning assembly in symmetrical screw, afterburning assembly comprises the first extension lever and the second extension lever, one end of the first extension lever is threaded with screw, between the first extension lever and the second extension lever, removably connect.
As preferably, be detachably connected as and be threaded.
Compared with prior art, the utility model has the advantage of: utilize the jackscrew be equipped with along the circumference uniform distribution of snap ring to be fixed on axle sleeve, stressed even, can not cause the distortion of axle sleeve, can avoid damaging because dismantling the improper machine envelope axle sleeve caused, reduce economic loss, improve maintenance efficiency.The utility model is easy to use, and processing cost is little, and can effectively reduce the workload of maintenance, and the machine that extends to similar high speed pump structure seals in the dismantlement work of axle sleeve.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, snap ring; 2, screw; 31, jackscrew; 32, fixed plate; 33, positioning head; 41, the first extension lever; 42, the second extension lever.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As a kind of mode of execution of the present utility model, consult Fig. 1, the utility model comprises snap ring 1, along the circumferential direction be processed with 4 screws 2 on snap ring 1, be provided with jackscrew 31 in laterally zygomorphic screw 2, the end that jackscrew 31 is positioned at snap ring 1 inside is fixedly connected with fixed plate 32, the other end that is positioned at snap ring 1 outside is fixed with positioning head 33, be provided with afterburning assembly in symmetrical screw 2, afterburning assembly comprises the first extension lever 41 and the second extension lever 42, one end of the first extension lever 41 is threaded with screw 2, between the first extension lever 41 and the second extension lever 42, removably connect.Be detachably connected as and be threaded.
The jackscrew 31 that the utility model utilization is equipped with along the circumference uniform distribution of snap ring 1 is fixed on axle sleeve, stressedly evenly can not cause the distortion of axle sleeve, can avoid damaging because dismantling the improper machine envelope axle sleeve caused, has reduced economic loss, has improved maintenance efficiency.The utility model is easy to use, and processing cost is little, and can effectively reduce the workload of maintenance, and the machine that extends to similar high speed pump structure seals in the dismantlement work of axle sleeve.Afterburning assembly comprises that an end of the first extension lever 41 and the second extension lever 42, the first extension levers 41 is threaded with screw 2, can regulate the length of afterburning assembly, utilizes lever principle, more is applicable to the needs different force and is dismantled.
Although in conjunction with current, be recognized as a most practical and preferred embodiment and described the utility model, but be to be understood that, the utility model is not limited to the disclosed embodiments, and is intended on the contrary contain multiple modification and equivalent arrangements included in the spirit and scope of the appended claims.
