Abstract
The utility model relates to a kind of laminating machine vacuum pump rotor axle sleeve extracting tool, comprise fairlead, front end locking nut, rear end locking nut and stress bolt, described fairlead is cylindric, described front end locking nut, rear end locking nut is located at fairlead two ends respectively, described stress bolt is connected with rear end locking nut: when described extracting tool uses, fairlead is set on axle sleeve, front end locking nut slides onto fairlead one end by armature spindle end face and locks, the rear end locking nut locking fairlead other end, stress bolt is connected to rear end locking nut, rotate stress bolt, dismantle axle sleeve in the axial direction.Compared with prior art, the utility model have safe and reliable, save the advantages such as artificial and time loss.
Description
Technical field
The utility model relates to a kind of provision for disengagement, especially relates to a kind of laminating machine vacuum pump rotor axle sleeve extracting tool.
Background technology
Laminating machine vacuum pump rotor is a kind of main auxiliary equipment generally general in solar photovoltaic assembly manufacture process, after the working rotor certain hour of main chamber, its epitrochanterian axle sleeve and oil sealing rotate because of continuous long-time (about 4000h ~ 16000h), the radial working face wearing and tearing of axle sleeve, reduce with the radial pressure of the contact portion of oil sealing or have minim gap, thus cause the pressure oil in cavity soak into or overflow, now need to change axle sleeve.Otherwise direct phenomenon is exactly oil leaking pollution working environment, cause working rotor positional precision overproof time serious, its result is exactly failure of vacuum pump.Because axle sleeve and rotor are excessive cooperations, vavuum pump runs certain hour rear axle housing and rotor engagement is tight especially, and maintenance personal can only cut open with portable abrasive wheel cutting machine and take off, and does labour intensity like this and easily injures rotor-end axle greatly, also.With other general machine drawing instrument easily skid, time-consuming, be difficult to unload.
Utility model content
The purpose of this utility model be exactly provide to overcome defect that above-mentioned prior art exists a kind of safe and reliable, save laminating machine vacuum pump rotor axle sleeve extracting tool that is artificial and time loss.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of laminating machine vacuum pump rotor axle sleeve extracting tool, comprise fairlead, front end locking nut, rear end locking nut and stress bolt, described fairlead is cylindric, described front end locking nut, rear end locking nut are located at fairlead two ends respectively, and described stress bolt is connected with rear end locking nut.
Described fairlead is formed by two semicircle fairleads cooperations, and when described extracting tool uses, two semicircle fairleads are set in respectively on axle sleeve and form complete fairlead.
The internal diameter of described front end locking nut and the external diameter of fairlead match.
The first screw thread for connecting fairlead and the second screw thread for being connected stress bolt is provided with inside the locking nut of described rear end.
Described stress bolt comprises the screw rod and bolt head that are connected, and described screw rod is connected with rear end locking nut.
Compared with prior art, the utility model is set in respectively on axle sleeve by two semicircle fairleads and forms complete fairlead, only need during use to be arranged on axle sleeve, bolt head is blocked by torque spanner, Rotating with Uniform, just easily axle sleeve can be pulled out in the axial direction, safe and reliable, effectively save artificial and time loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, a kind of laminating machine vacuum pump rotor axle sleeve extracting tool, comprise fairlead 1, front end locking nut 2, rear end locking nut 3 and stress bolt 4, fairlead 1 is cylindric, front end locking nut 2, rear end locking nut 3 are located at fairlead 1 two ends respectively, and stress bolt 4 is connected with rear end locking nut 3.Fairlead 1 is formed by two semicircle fairleads cooperations.The internal diameter of front end locking nut 2 and the external diameter of fairlead 1 match.The first screw thread for connecting fairlead 1 and the second screw thread for being connected stress bolt 4 is provided with inside rear end locking nut 3.Stress bolt 4 comprises the screw rod and bolt head that are connected, and screw rod is connected with rear end locking nut 3.
When above-mentioned extracting tool uses, two semicircle fairleads are set in respectively on axle sleeve and form complete fairlead 1, front end locking nut 2 slides onto fairlead 1 one end by armature spindle end face and locks, rear end locking nut 3 locks fairlead 1 other end, stress bolt 4 is connected to rear end locking nut 3, rotates stress bolt 4, dismantles axle sleeve in the axial direction, safe and reliable, effectively save artificial and time loss.
