Description

Technical Field

[0001] This utility model relates to the field of bearing sleeves, and specifically to a machine tool bearing ring shaping device for quick clamping. Background Technology

[0002] Bearing rings are ring-shaped parts of radial rolling bearings with one or more raceways. In traditional bearing ring production, it is easy to cause inconsistent inner wall thickness, which requires remelting and remanufacturing, resulting in high production costs. Therefore, in order to avoid high production costs, bearing processing companies now usually adopt the method of shaping and then tempering to recover losses.

[0003] In the current bearing ring forming process, ordinary jigs are used to hold the bearing rings and the deformed rings are shaped by hammering. The hammering method not only requires a lot of manpower, but it is also difficult to control the hammering force, which can easily damage the surface of the bearing rings. At the same time, the clamping process of ordinary jigs is usually cumbersome and requires a certain amount of time and manpower, which affects the processing efficiency to some extent.

[0004] Therefore, it is necessary to invent a quick-clamping machine tool bearing ring shaping device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a quick-clamping machine tool bearing race forming device. The device involves placing the bearing race on a race frame, then turning on a cylinder switch to push a connecting rod, which in turn rotates the connecting block inside the race frame. The rotation of the connecting block causes an external inclined block to press against the surrounding telescopic rods, which in turn push a clamping block to rotate on a fixed frame. This allows the clamping block to fit tightly around the bearing race, achieving quick clamping. This addresses the problem mentioned in the background section where existing bearing races are clamped using ordinary fixtures during the forming process, and deformed races are reshaped by hammering. Hammering requires significant manpower, and the hammering force is difficult to control, easily damaging the bearing race surface. Furthermore, the clamping process with ordinary fixtures is usually cumbersome, requiring considerable time and manpower, which negatively impacts processing efficiency.

DETAILED DESCRIPTION

[0024] In order to make those skilled in the art better understand the technical scheme of the utility model, the utility model will be further described in detail in conjunction with the drawings.

[0025] The utility model provides a kind of machine tool bearing ring shaping device of quick clamping as shown in Figures 1-5 It is the overall structure schematic view of the utility model;

[0026] Mobile assembly 2 is installed above base 1, for moving, the top of base 1 is fixedly connected with support frame 4, the top of support frame 4 is provided with hydraulic cylinder 5, the output end of hydraulic cylinder 5 is fixedly connected with top plate 6, the lower portion of top plate 6 is provided with lower plate 7, the lower portion of lower plate 7 is fixedly connected with connecting seat 10, one side of connecting seat 10 is penetrated with bolt 11, and shaping pressure head 12 is fixedly installed in the inside of connecting seat 10.

[0027] The fast clamping mechanism 3 is installed above the moving assembly 2 and is used for clamping the bearing ring. The bearing ring is placed on the sleeve frame 301, and then the air cylinder 304 switch is opened to push the connecting rod 303 to drive the connecting block 302 inside the sleeve frame 301 to rotate. The rotation of the connecting block 302 causes the external inclined block to extrude the telescopic rods 306 around to extend and retract. The telescopic rods 306 extend and retract to push the clamping block 308 to rotate on the fixed frame 307, so that the clamping block 308 is tightly attached around the bearing ring, thereby achieving fast clamping.

[0028] As shown in Figure 1 and Figure 2 , the moving assembly 2 includes a support 201 installed above the base 1. The rear side of the support 201 is fixedly provided with a driving motor 202. The output end of the driving motor 202 is fixedly connected with a lead screw 203. The outer part of the lead screw 203 is movably connected with a moving seat 206. The driving motor 202 is turned on to drive the lead screw 203 to rotate, and the outer moving seat 206 is moved forward and backward by the rotation of the lead screw 203, so that the moving seat 206 moves to the range of the shaping processing. In this way, the bearing ring does not need to be directly placed below the shaping processing, which not only avoids accidents, but also reduces the risk.

[0029] As shown in Figure 2 , the upper sides of the support 201 are fixedly connected with sliding rails 204. The outer parts of the sliding rails 204 are movably connected with sliding blocks 205. The moving seat 206 is fixedly connected with the sliding blocks 205. When the moving seat 206 moves by the rotation of the lead screw 203, the sliding blocks 205 on the lower sides of the moving seat 206 move outside the sliding rails 204 on the support 201, thereby improving the stability of the moving seat 206.

[0030] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the drawings, the quick clamping mechanism 3 comprises a sleeve frame 301 mounted above the moving seat 206, a connecting block 302 movably connected inside the sleeve frame 301, a connecting rod 303 fixedly connected to one side of the connecting block 302, a pneumatic cylinder 304 movably connected to one side of the connecting rod 303, a rotating disc 305 fixedly connected above the connecting block 302, telescopic rods 306 movably connected around the inside of the sleeve frame 301, a fixed frame 307 fixedly connected around the outside of the sleeve frame 301, clamping blocks 308 movably connected inside the fixed frame 307, anti-slip protrusions 309 fixedly arranged on the side surfaces of the clamping blocks 308, the bearing ring is placed on the sleeve frame 301 first, then the pneumatic cylinder 304 switch is turned on, the connecting rod 303 is pushed to drive the connecting block 302 inside the sleeve frame 301 to rotate, the telescopic rods 306 around the sleeve frame 301 are extruded to expand or contract, the clamping blocks 308 on the fixed frame 307 are pushed to rotate through the telescopic rods 306, so that the clamping blocks 308 are tightly attached around the bearing ring, and quick clamping is realized.

[0031] As shown in the drawings, Figure 3 and Figure 4 As shown in the drawings, the telescopic rods 306 and the clamping blocks 308 are provided in three groups, the three groups of telescopic rods 306 and the clamping blocks 308 are arranged in a ring array around the sleeve frame 301, the bearing ring is clamped around by the three groups of clamping blocks 308, the clamping range is improved, and the stability of clamping the bearing ring is improved.

[0032] As shown in the drawings, Figure 1 and Figure 5 As shown in the drawings, the two sides of the upper plate 7 are fixedly connected with movable rods 8, the movable rods 8 are movably connected with the top plate 6, and the outside of the movable rods 8 is provided with springs 9, when the hydraulic cylinder 5 pushes the top plate 6 to contact the lower plate 7 and the shaping pressure head 12 to the bearing ring, in order to avoid that the compacting force is too large to cause damage to the bearing ring, when the lower plate 7 and the shaping pressure head 12 are pressed down, the movable rods 8 around the lower plate 7 are telescoped and moved in the top plate 6, and the springs 9 outside the movable rods 8 play a buffering role between the lower plate 7 and the top plate 6, so that damage to the bearing ring is avoided when the bearing ring is shaped and compacted.

[0033] The working principle of this utility model is as follows: First, connect the external power supply. Then, place the bearing ring to be shaped on the sleeve 301. Next, turn on the cylinder 304 switch, pushing the connecting rod 303 to rotate the connecting block 302 inside the sleeve 301. The rotation of the connecting block 302 causes the external inclined block to press the telescopic rod 306 around the perimeter to extend and retract. The extension and retraction of the telescopic rod 306 pushes the clamping block 308 to rotate on the fixed frame 307, thus making the clamping block 308 close to the bearing ring, achieving quick clamping. After clamping and fixing, turn on the drive motor 202 switch, driving the lead screw 203 inside the bracket 201 to rotate. The rotation of the lead screw 203 drives the external moving seat 206, quick clamping mechanism 3, and bearing ring to move to the shaping processing area. After moving to the shaping area, turn off the drive motor 202 switch, and then turn on the hydraulic cylinder 5 switch, pushing the top plate 6, the lower plate 7, and the shaping pressure head 12 below to neatly press the bearing ring. In practice, the movable rods 8 around the lower plate 7 extend and retract within the top plate 6. The springs 9 outside the movable rods 8 act as a buffer between the lower plate 7 and the top plate 6, thus preventing damage during the shaping and pressing of the bearing race. Pressure is applied to the bearing race by the shaping pressure head 12, thereby shaping the bearing race. After shaping, the hydraulic cylinder 5 switch is turned off, and the shaping pressure head 12 is raised and lowered to the initial position. Then, the drive motor 202 switch is turned on, driving the lead screw 203 to rotate. The lead screw 203 drives the moving seat 206 and the shaped bearing race to slide forward. Finally, the drive motor 202 switch is turned off, and the shaped bearing race is removed by quickly reversing the previous steps. Then, the next bearing race that needs to be shaped is placed in. Finally, when the device is no longer in use, all drive power is turned off, and the external power is disconnected. This completes the use of the quick-clamping machine tool bearing race shaping device.
