Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical disassembly tools, and specifically relates to a bearing auxiliary removal device for the maintenance of mechanical equipment. Background Art

[0002] After mechanical equipment has been used for a period of time, various faults often occur. At this time, mechanical workers are required to carry out repairs and maintenance. The damage of bearings or bushings is a common type of mechanical fault. When the bearing or bushing is too tightly fitted with the shaft body, or the bearing and bushing are corroded and rusted after long-term operation, or the bearing is worn or seized due to poor lubrication, etc., it is necessary to disassemble it at this time. Most of the existing disassembly methods are to disassemble the bearing or bushing by destructive methods such as heating and expansion or hammering, which is neither safe nor efficient. Therefore, it is necessary to propose a bearing auxiliary removal device for the maintenance of mechanical equipment to solve the above problems. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present utility model provides a bearing auxiliary removal device for the maintenance of mechanical equipment, which has the advantage of being convenient for quickly removing the bearing or bushing sleeved on the surface of the shaft body, and solves the problem that it is difficult for mechanical workers to quickly remove the bearing or bushing on the surface of the shaft body.

[0004] The technical solution of the present invention is as follows: A bearing auxiliary removal device for the maintenance of mechanical equipment includes: a reaction seat, a reaction screw is arranged on the top of the reaction seat, the reaction screw is connected with a pull ring through an internally threaded tube, a nut is arranged at the top end of the internally threaded tube, the pull ring is connected with a first clamping plate through a connecting rod, and the first clamping plate is connected with a second clamping plate through an adjusting screw.

[0005] Further, a limiting flange is arranged at the bottom end of the internally threaded tube, and the bottom of the pull ring abuts against the top of the limiting flange.

[0006] Further, a positioning block is arranged on the side surface of the pull ring, the top end of the connecting rod is hinged inside the positioning block, and the connecting rod is connected with the first clamping plate through an adjusting structure.

[0007] Further, the adjusting structure includes a top block, a connecting block, a limiting plate and a locking screw. The top block is connected with the limiting plate through the connecting block. A sliding groove is formed inside the first clamping plate. The limiting plate is movably connected inside the sliding groove. The locking screw is connected with the first clamping plate through the limiting plate.

[0008] Further, a threaded through hole is formed inside the limiting plate. The locking screw is threadedly connected inside the threaded through hole. The bottom end of the locking screw abuts against the inner bottom wall of the sliding groove.

[0009] Further, a through groove is formed inside the second clamping plate, the adjusting screw rod is movably inserted into the through groove, a fastening nut is threadedly connected to the side surface of the adjusting screw rod, and the end face of the fastening nut abuts against the side surface of the second clamping plate.

[0010] Further, tooth grooves are formed at the bottom of the first clamping plate and the top of the second clamping plate.

[0011] Further, a communication groove is formed in the inner top wall of the sliding groove, and the connecting block is movably connected to the communication groove.

[0012] The beneficial effects of the present invention are as follows:

[0013] By turning the nut, the inner threaded tube can be driven to rotate, thereby forcing the inner threaded tube to move upward. Under the action of the limiting flange, the pull ring will move upward synchronously, thereby driving the pull rod, the first clamping plate and the second clamping plate to move. Since the shaft sleeve is clamped between the first clamping plate and the second clamping plate, after the pull rod rises, the shaft sleeve will also move upward together until the shaft sleeve is separated from the shaft part, achieving the effect of facilitating the rapid removal of the bearing or sleeve sleeved on the shaft surface, and solving the problem that it is difficult for mechanical workers to quickly remove the bearing or sleeve on the shaft surface.

[0014] By loosening the locking screw, the limiting plate slides in the sliding groove, thereby playing a role in adjusting the force application point of the first clamping plate, achieving the effect of making the bottom of the first clamping plate and the top of the second clamping plate horizontally abut against the two end faces of the shaft sleeve, and solving the problem that when the force application point of the first clamping plate is too close to the adjusting screw rod, the first clamping plate and the second clamping plate are prone to lateral displacement when the connecting rod is in tension.

[0023] In the present invention, unless otherwise clearly specified and limited, terms such as "set", "installed", "connected", "connected" should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or integrated; the connection can be a mechanical connection or an electrical connection; the connection can be a direct connection or an indirect connection through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Refer to Figures 1-5 , a bearing auxiliary removal device for mechanical equipment maintenance, including a reaction seat (1). A reaction screw 2 is arranged at the top of the reaction seat 1. The reaction seat 1 is a frustum of a cone. The reaction screw 2 and the reaction seat 1 are integrally formed, and the axis line of the reaction screw 2 and the axis line of the reaction seat 1 are collinear. The reaction screw 2 is connected with a pull ring 5 through an internal thread tube 3. The side surface of the reaction screw 2 is in threaded connection with the internal thread of the internal thread tube 3. The pull ring 5 is movably sleeved on the internal thread tube 3. A nut 6 is arranged at the top end of the internal thread tube 3. The nut 6 and the internal thread tube 3 are integrally formed, and the nut 6 and the internal thread tube 3 are concentrically arranged. The pull ring 5 is connected with a first clamping plate 9 through a connecting rod 8. The number of the connecting rods 8 is three in total, and the distance between each two is 120 degrees. Each connecting rod 8 is equipped with a first clamping plate 9. The first clamping plate 9 is connected with a second clamping plate 11 through an adjusting screw 10. Each first clamping plate 9 is equipped with an adjusting screw 10 and a second clamping plate 11.

[0025] Refer to Figure 4, a limiting flange 4 is provided at the bottom end of the internally threaded tube 3, and the bottom of the pull ring 5 abuts against the top of the limiting flange 4. At this time, the limiting flange 4 and the nut 6 together play a role in restricting the movement trajectory of the pull ring 5, so that the pull ring 5 can only rotate around the axial line of the internally threaded tube 3, preventing the pull ring 5 from detaching from the internally threaded tube 3.

[0026] Refer to Figure 1 , a positioning block 7 is provided on the side surface of the pull ring 5. There are three positioning blocks 7 in total, and each connecting rod 8 has a separate positioning block 7 corresponding to it. The top end of the connecting rod 8 is hinged to the inside of the positioning block 7. The connecting rod 8 is connected to the first clamping plate 9 through an adjusting structure. The connecting rod 8 can rotate relative to the positioning block 7, and the first clamping plate 9 can also rotate relative to the connecting rod 8 through the adjusting mechanism, increasing the rotatable range of the first clamping plate 9, so that the device can be applied to the disassembly of bushings of more models and sizes.

[0027] Refer to Figures 2-5 , the adjusting structure includes a top block 13, a connecting block 14, a limiting plate 15 and a locking screw 17. The top block 13 is connected to the limiting plate 15 through the connecting block 14. A sliding groove 16 is opened inside the first clamping plate 9. The limiting plate 15 is movably connected to the inside of the sliding groove 16. A communication groove is opened on the inner top wall of the sliding groove 16. The connecting block 14 is movably connected to the inside of the communication groove. The locking screw 17 is connected to the first clamping plate 9 through the limiting plate 15. The limiting plate 15 can slide freely in the sliding groove 16 without external force restriction, so as to adjust the force position of the first clamping plate 9 to better separate the bushing from the shaft part. A threaded through hole 18 is opened inside the limiting plate 15. The locking screw 17 is threadedly connected to the inside of the threaded through hole 18. The bottom end of the locking screw 17 abuts against the inner bottom wall of the sliding groove 16. When the locking screw 17 is tightened, the bottom end of the locking screw 17 abuts tightly against the inner bottom wall of the sliding groove 16, so that the limiting plate 15 moves upward in the reverse direction until the top of the limiting plate 15 abuts against the inner top wall of the sliding groove 16, thus playing a role in restricting the movement of the limiting plate 15.

[0028] Refer to Figure 1 , a through groove is opened inside the second clamping plate 11. The adjusting screw 10 is movably inserted into the through groove. A fastening nut 12 is threadedly connected to the side surface of the adjusting screw 10. The end face of the fastening nut 12 abuts against the side surface of the second clamping plate 11. Each adjusting screw 10 is equipped with two fastening nuts 12. The two fastening nuts 12 clamp the second clamping plate 11 between them to play a role in restricting the movement of the second clamping plate 11. Tooth grooves are opened at the bottom of the first clamping plate 9 and the top of the second clamping plate 11. The tooth grooves can increase the friction between the clamping plate and the bushing, preventing the clamping plate from detaching from the bushing.

[0029] In use, first turn the fastening nut 12 to adjust the second clamping plate 11 to a proper position. Then, place the bottom of the first clamping plate 9 against the top end of the bushing. Next, turn the fastening nut 12 to make the top of the second clamping plate 11 against the bottom end of the bushing, and tighten the fastening nut 12. Then, loosen the locking screw 17 and adjust the relative position of the limiting plate 15 and the first clamping plate 9 to make the force application point of the first clamping plate 9 as close to the center as possible. Then, tighten the locking screw 17. Finally, use a wrench to turn the nut 6 to drive the upward movement of the internally threaded tube 3, so that the sleeve and the shaft rod move relatively until the sleeve is separated from the shaft rod.
