Description

Technical Field

[0001] The invention belongs to the technical field of grinding and polishing the inner side of a bearing, and in particular relates to a bearing inner ring processing device. Background Art

[0002] The inner ring of the bearing is a key component of the rolling bearing. It is located inside the bearing and is usually used in conjunction with the shaft journal. For example, in a bearing mounted on a motor shaft, the inner ring fits tightly around the outer circumference of the motor shaft. Its main function is to provide a stable annular raceway for the rolling elements and rotate with the shaft.

[0003] In the prior art, after the production of the inner ring of the bearing is completed, the inner wall of the inner ring of the bearing needs to be ground and polished so that the inner ring of the bearing can be matched with the shaft neck with higher precision.

[0004] When grinding and polishing the inner ring of the bearing, the inner ring is clamped and fixed by a fixture at the processing lathe position, and then the inner side of the inner ring of the bearing is probed into by the grinding structure. The inner wall of the inner ring of the bearing is grinded and polished by the grinding structure. After polishing, the inner ring of the bearing is removed from the fixture position. The whole process is inefficient. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a bearing inner ring grinding device with high grinding efficiency.

[0006] The technical solution adopted to solve the above technical problems is: a bearing inner ring processing device, including a chain plate conveyor belt arranged in a processing support frame, a plurality of evenly distributed inner ring fixers for fixing the bearing inner ring are fixedly connected to the surface of the chain plate conveyor belt, and an integrated processing structure for polishing the bearing inner ring is fixedly connected to the middle of any one side of the processing support frame.

[0007] Through the above technical solution, the chain plate conveyor can drive the inner ring fixer to move, and the inner ring of the bearing is clamped and fixed by the inner ring fixer. When the chain plate conveyor drives the corresponding inner ring fixer to move to the processing integrated structure position, the inner ring of the bearing at the position of the inner ring fixer is polished through the processing integrated structure, with a high degree of mechanization and high polishing efficiency.

[0008] Several of the inner ring fixers include a fixed mounting seat that is fixedly connected to the chain conveyor belt, a protective shell is fixedly connected to the upper surface of the fixed mounting seat, a limit adjustment structure is provided on the inner wall of the protective shell, and two symmetrically arranged inner ring clamps for clamping and fixing the inner ring of the bearing are provided on the upper surface of the protective shell.

[0009] Through the above technical scheme, the fixed mounting seat is made of stainless steel material, which is fixedly connected to the chain plate of the chain conveyor belt, so that the inner ring fixer can be stably fixed on the surface of the chain conveyor belt, making it more stable during operation and grinding. The protective shell can protect its internal structure to prevent metal powder from falling onto the internal structure during grinding and affecting the normal use of the internal structure. The protective shell has the function of fixing and supporting its internal structure. The limit adjustment structure can be fixed and positioned when the inner ring clamp is pressed down and closed, so that the inner ring of the bearing is fully fixed by the inner ring clamp.

[0010] Furthermore, a guide arc block is fixedly connected to the center position of the upper surface of the fixed mounting seat, a circular arc groove is provided on the upper surface of the guide arc block, and a mounting groove is opened at the bottom position of the circular arc groove of the guide arc block, and a lifting spring is fixedly connected to the bottom position of the mounting groove.

[0011] Through the above technical scheme, the arc-shaped groove set at the position of the guide arc block is set in a "U" shape, which can be slidably matched with the rotating connecting claw set in the arc shape, so that the horizontal positioning blocks can cooperate with each other, and the installation groove set at the position of the guide arc block can be used to install the lifting spring, and when the lifting spring is pressed down by the rotating connecting claw, the lifting spring is compressed to store energy, and when the limit adjustment structure no longer fixes the rotating connecting claw, the lifting spring quickly lifts up to reset the inner ring clamp.

[0012] Furthermore, the lower surfaces of the two inner ring clamps are fixedly connected with arc-shaped rotating connecting claws, the outer sides of the rotating connecting claws are slidably connected with the arc-shaped grooves of the guide arc block, and the bottoms of the two rotating connecting claws are tightly pressed against the tops of the lifting springs, and the two rotating connecting claws pass through a rotating connection limited fixed shaft, and clamping fixing structures are provided at both ends of the limited fixed shaft near the limit adjustment structure, and the two ends of the limit fixed shaft are slidably connected with the side walls of the protective shell.

[0013] Through the above technical scheme, when the rotating connecting claw rotates at the position of the limit fixing shaft, the inner ring clamping claw can be closed or expanded, and the inner ring of the bearing can be clamped or loosened. The limit fixing shaft can be installed with the limit rotating connecting claw, and the rotating connecting claw can rotate around the limit fixing shaft to adjust the closing and expansion of the inner ring clamping claw, and the limit fixing shaft can make the rotating connecting claw move in the vertical direction, so that the rotating connecting claw cooperates with the arc groove of the guide arc block, and the clamping and fixing structure can cooperate with the limit adjustment structure to assist in fixing the limit fixing shaft.

[0014] Furthermore, the clamping and fixing structure includes a spring groove opened on the surface of the limiting fixing shaft, a clamping slider is slidably connected to the inner wall of the spring groove, a slope is provided on the lower surface of the clamping slider, and a clamping spring is fixedly connected between the clamping slider and the inner wall of the spring groove.

[0015] Through the above technical scheme, the spring groove can be used to install the clamping slider and the clamping spring. The lower surface of the clamping slider is provided with a slope that can cooperate with the slope on the upper surface of the positioning pin, so that the clamping slider cooperates with the positioning pin, so that the clamping slider is pressed into the spring groove, so that the limit fixing shaft is pressed downward, and the clamping spring causes the clamping slider to reset and eject, and the clamping slider is blocked by the positioning pin to prevent the limit fixing shaft from rebounding.

[0016] Furthermore, the limit adjustment structure includes a limit slot block fixedly connected to the inner wall of the protective shell, the limit slot block is slidably connected to a limit slider, the limit slider is fixedly connected to a positioning fixed block, and a number of evenly distributed pin slots are opened at both ends of the positioning fixed block from top to bottom, and a number of positioning pins are slidably connected to the inner walls of the pin slots, a positioning spring is fixedly connected between the positioning pin and the inner wall of the pin slot, and a slope is arranged on the upper surface of the positioning pin.

[0017] Through the above technical scheme, the limit slot block can support and limit the limit slider, which is convenient for lateral adjustment of the limit adjustment structure. When the limit slider and the positioning fixed block move laterally and the positioning pin no longer cooperates with the clamping slider, the toggle rod is controlled to rebound under the action of the lifting spring.

[0018] Furthermore, a control toggle rod is fixedly connected to the middle position of either side of the positioning and fixing block, the control toggle rod is slidably connected to the protective shell, a slope is provided at one end of the control toggle rod outside the protective shell, a return spring is fixedly connected between the side of the positioning and fixing block close to the control toggle rod and the inner wall of the protective shell, and the return spring and the control toggle rod are concentrically arranged.

[0019] Through the above technical solution, when the inner ring fixer moves as a whole and the control toggle rod moves to the toggle block position, the toggle block will squeeze the control toggle rod, so that the control toggle rod will squeeze the positioning fixing block, causing the positioning fixing block to move sideways, so that the positioning pin is separated from the clamping slider, and the inner ring clamping claw is separated. During this process, the reset spring is stretched, and when the control toggle rod is no longer in contact with the toggle block, the positioning fixing block is laterally moved and reset under the action of the reset spring.

[0020] Furthermore, the inner walls of the two inner ring clamps are fixedly connected with elastic pads, the elastic pads are made of copper material, and horizontal positioning blocks are fixedly connected to both sides of the two inner ring clamps.

[0021] Through the above technical solution, the elastic pad made of copper material is relatively soft, and will not cause indentations on the surface of the inner ring of the bearing when the inner ring of the bearing is clamped by the inner ring clamp, thereby effectively protecting the inner ring of the bearing. The horizontal positioning block can position the inner ring of the bearing laterally to avoid the inner ring of the bearing from escaping from the inner ring clamp during grinding and polishing.

[0022] Furthermore, a main drive motor is fixedly connected to the side wall of the processing support frame via a fixed frame, and a driving end of the main drive motor is connected to the rotating shaft of the chain conveyor belt through a reducer toward the side of the chain conveyor belt, and a toggle block is fixedly connected to one end of the upper surface of the processing support frame and close to the side of the control toggle rod.

[0023] Through the above technical solution, the main drive motor provides power for the operation of the chain conveyor belt, and the reducer can keep the chain conveyor belt at a suitable speed and increase the output torque of the main drive motor. The toggle rod can be adjusted and controlled by the toggle block to expand the inner ring clamp. When the chain conveyor belt moves to the end of the processing support frame, the polished inner ring of the bearing is collected in the item collection structure under the action of gravity.

[0024] Furthermore, the integrated processing structure includes a polishing platform fixedly connected to the middle position of the side wall of the processing support frame, the upper surface of the polishing platform is fixedly connected to a level adjuster for adjusting in the X-axis direction and the Y-axis direction, the surface of the level adjuster is fixedly connected to a height adjuster, and the telescopic end of the height adjuster is fixedly connected to the polishing machine body.

[0025] Through the above technical solution, the polishing platform can support the entire integrated processing structure, and the horizontal adjuster allows the polishing machine body to move together with the inner ring fixer. At the same time, the horizontal adjuster facilitates the polishing head of the polishing machine body to extend into the inner side of the bearing inner ring, and the horizontal adjuster allows the polishing machine body and the bearing inner ring to move synchronously for easy polishing. The horizontal adjuster is composed of two vertically crossed electric linear guides, which can realize the adjustment of the height adjuster and the polishing machine body in the X-axis and Y-axis directions.

[0026] The beneficial effects of the present invention are as follows: the present invention arranges an inner ring fixer, places the inner ring of the bearing to be polished between the inner ring claws at corresponding positions, and presses the inner ring of the bearing downward so that the inner ring of the bearing is clamped and fixed, and then the inner ring of the bearing is polished by the polishing machine body. After polishing, the two inner ring claws can be unfolded by the toggle block. When the inner ring of the bearing rotates to the bottom of the chain plate conveyor belt, the inner ring of the bearing falls under the action of gravity, and automatic material removal is completed. The entire polishing process is efficient and highly mechanized. The manual operation part is far away from the polishing machine body, and the operation is safer. BRIEF DESCRIPTION OF THE DRAWINGS

The fixed mounting seat 20 is made of stainless steel and is fixedly connected to the chain plate of the chain conveyor belt 3 to stably fix the inner ring fixer 2 on the surface of the chain conveyor belt 3, so that it is more stable during operation and grinding. The protective shell 201 can protect its internal structure to prevent metal powder from falling into the internal structure during grinding and affecting the normal use of the internal structure.

The limit adjustment structure can be fixed and positioned when the inner ring clamps 202 are pressed down and closed, so that the inner ring of the bearing is fully fixed by the inner ring clamps 202.

[0040] The inner walls of the two inner ring clamps 202 are fixedly connected with elastic pads 210, which are made of copper material. Horizontal positioning blocks 200 are fixedly connected at both sides of the two inner ring clamps 202. The elastic pads 210 made of copper are relatively soft.

When the inner ring fixer 2 moves as a whole, when the control toggle rod 26 moves to the position of the toggle block 6, the toggle block 6 will squeeze the control toggle rod 26, so that the control toggle rod 26 will squeeze the positioning and fixing block 27, causing the positioning and fixing block 27 to move sideways, so that the positioning pin 206 is separated from the clamping slider 209, and the inner ring clamping claw 202 is separated. In this process, the return spring 25 is stretched, and when the control toggle rod 26 is no longer in contact with the toggle block 6, the positioning and fixing block 27 is laterally moved and reset under the action of the return spring 25.

[0044] The lower surfaces of the two inner ring clamping jaws 202 are fixedly connected with arc-shaped rotating connecting claws 29, the outer sides of the rotating connecting claws 29 are slidably connected with the arc-shaped grooves of the guide arc block 21, and the bottoms of the two rotating connecting claws 29 are tightly pressed against the tops of the lifting springs 22, the two rotating connecting claws 29 penetrate the rotating connection limited position fixed shaft 24, and the two ends of the limited fixed shaft 24 are provided with clamping and fixing structures near the position of the limit adjustment structure, the two ends of the limited fixed shaft 24 penetrate and slide with the side walls of the protective shell 201, and the rotating connecting claws 29 are in the limited fixed shaft 24. When the position is rotated, the inner ring clamping jaws 202 can be closed or expanded, and the inner ring of the bearing can be clamped or loosened.

[0046] The working principle of this embodiment is as follows: when the corresponding inner ring of the bearing needs to be polished, the inner ring of the bearing is placed between the two inner ring clamping jaws 202, and the inner ring of the bearing is pressed downward, so that the inner ring clamping jaws 202 and the rotating connecting jaws 29 move downward, and under the action of the guide arc block 21, the two rotating connecting jaws 29 are brought together, and then the two inner ring clamping jaws 202 are brought together to fix and clamp the inner ring of the bearing, and the height adjuster 42 is adjusted so that the center of the grinding head of the polishing machine body 41 and the center of the clamped inner ring of the bearing are on the same horizontal plane, and the main drive motor 5 and the level adjuster 43 are started;

[0047] The main driving motor 5 drives the chain conveyor belt 3 to move.

The level adjuster 43 drives the height adjuster 42 and the polishing machine body 41 to move together with the chain conveyor belt 3, so that the inner ring of the bearing is fully polished. After the polishing is completed, the polishing machine body 41 moves out of the inner ring of the bearing.

[0048] When the inner ring fixer 2 moves to the position of the toggle block 6, the toggle block 6 will squeeze the control toggle rod 26, so that the control toggle rod 26 drives the positioning fixing block 27 to move laterally at the position of the limit slot block 28, and the positioning pin 206 is separated from the clamping slider 209. Under the action of the lifting spring 22, the two inner ring clamps 202 are expanded and no longer clamp the inner ring of the bearing. When the inner ring fixer 2 moves to the lower position of the processing support frame 1 with the chain plate conveyor belt 3, the polished inner ring of the bearing falls under the action of gravity, completing the unloading.
