Description

Technical Field

[0001] This utility model belongs to the field of support shaft grinding technology, specifically relating to a support shaft grinding device with a bidirectional synchronous clamping mechanism. Background Technology

[0002] Support shafts are core components in mechanical systems used to bear loads and maintain the stable operation of parts. Their core function is to provide stable support for rotating or moving parts through their rigidity and positioning accuracy, while reducing vibration and friction to ensure the stability and accuracy of equipment operation. Support shafts are usually composed of shaft bodies, positioning steps, mounting holes, etc. The shaft body is made of high-strength metal materials (such as 45 steel, stainless steel, alloy structural steel) and undergoes heat treatment processes such as tempering and quenching to improve hardness and wear resistance. The surface is often treated with chrome plating, phosphating, etc. to enhance rust prevention. Support shafts need to be ground during the processing.

[0003] Currently, existing support shaft grinding devices typically require the support shaft to be fixed first, and then the outer wall of the fixed support shaft is ground by operating the grinding mechanism. However, traditional support shaft grinding devices often only clamp and fix shorter support shafts in one direction. When fixing and grinding support shafts of different lengths, it may cause slight deformation or vibration of the workpiece, thereby reducing the processing stability. Utility Model Content

This invention aims to solve the problem that existing support shaft grinding devices typically require fixing the support shaft first, and then operating the grinding mechanism to grind the outer wall of the fixed support shaft. However, traditional support shaft grinding devices often only clamp and fix shorter support shafts in one direction. When fixing and grinding support shafts of different lengths, slight deformation or vibration of the workpiece may occur, thereby reducing the processing stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support shaft grinding device with a bidirectional synchronous clamping mechanism, including a worktable, a fixed frame fixedly connected to the top of the worktable, a first motor mounted on the top of the fixed frame, a lead screw connected to the output end of the first motor, and a threaded connecting block threadedly connected to the outer wall of the lead screw; An electric telescopic rod is installed at the bottom of the threaded connecting block.

[0011] As a preferred embodiment of the support shaft grinding device with a bidirectional synchronous clamping mechanism of this utility model, the limiting block can form an elastic structure with the mounting base through a spring and a connecting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By placing the support shaft between two connecting seats, and then using a second motor to drive the bidirectional lead screw to rotate clockwise, the two threaded sleeves connected to the outer wall can drive the movable block to move towards each other along the guide rod.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6 The present invention provides the following technical solution: a support shaft grinding device with a bidirectional synchronous clamping mechanism, including a worktable 1, a fixed frame 2 fixedly connected to the top of the worktable 1, a first motor 3 installed on the top of the fixed frame 2, a lead screw 4 connected to the output end of the first motor 3, and a threaded connecting block 5 threadedly connected to the outer wall of the lead screw 4. It should be noted that the top of the fixed frame 2 is provided with a guide groove, and one end of the threaded connecting block 5 is located inside the guide groove, so as to play a guiding role when the screw 4 rotates and drives the threaded connecting block 5 to move. An electric telescopic rod 6 is installed at the bottom of the threaded connecting block 5. A grinder 7 is installed at the output end of the electric telescopic rod 6. A second motor 8 is installed at one end of the worktable 1. A bidirectional lead screw 9 is connected to the output end of the second motor 8. Two threaded sleeves 10 are threadedly connected to the outer wall of the bidirectional lead screw 9. A movable block 11 is fixedly connected to the outer wall of the two threaded sleeves 10. A connecting frame 22 is fixedly connected to the top of the movable block 11. A connecting seat 12 is installed at one end of the connecting frame 22. A locking bolt 13 passes through the thread on the outer wall of the connecting seat 12. In actual use, the first motor 3 drives the lead screw 4 to rotate. At this time, the threaded connecting block 5 connected to the outer wall of the lead screw will drive the grinding machine 7 to move laterally along the guide slide. The electric telescopic rod 6 can control the grinding machine 7 to rise and fall, so that the rotating grinding wheel can contact the outer wall of the fixed support shaft at the bottom, thereby realizing the grinding process.

[0018] Preferably, a guide rod 14 is fixedly connected to the inner side of the workbench 1, one end of the movable block 11 is sleeved on the outer wall of the guide rod 14, and the end of the bidirectional lead screw 9 away from the second motor 8 forms a rotating connection structure with the workbench 1 through a bearing. Two connecting seats 12 are provided, and the two connecting seats 12 are symmetrically distributed between them.

[0019] In practical use, the support shaft is placed between two connecting seats 12, and then the second motor 8 drives the bidirectional lead screw 9 to rotate clockwise, so that the two threaded sleeves 10 connected to the outer wall can drive the movable block 11 to move towards each other along the guide rod 14. At the same time, the connecting bracket 22 at the top of the two threaded sleeves 10 will drive the two connecting seats 12 to move towards each other. After the two ends of the support shaft pass through the inside of the connecting seat 12, the two ends of the support shaft are fixed by tightening the locking bolts 13, so that support shafts of different lengths can be clamped in both directions synchronously.

[0020] Preferably, a protective baffle 15 is hinged to the outer wall of the workbench 1, a mounting base 16 is fixedly connected to one end of the protective baffle 15, a spring 17 is installed on the inner side of the mounting base 16, a connecting block 18 is connected to one end of the spring 17, a limit plug 19 is fixedly connected to one end of the connecting block 18, a fixing block 20 is fixedly connected to the top of the workbench 1, and a limit slot 21 is opened on the top of the fixing block 20.

[0021] In practical use, the connecting block 18 is moved by the lever to retract the limiting insert 19, and then the protective baffle 15 is flipped to make it stand upright. At this time, by releasing the lever, the limiting insert 19 will pop out under the action of the spring 17 and insert into the limiting slot 21 at the top of the fixed block 20, so that the upright protective baffle 15 can protect the front of the device. It should be noted that the inner side of the protective baffle 15 is made of transparent acrylic material, which can provide front protection while also allowing staff to easily check the progress of the support shaft processing and polishing.

[0022] Preferably, the end of the limiting plug 19 away from the connecting block 18 is adapted to the size of the limiting slot 21, and the limiting plug 19 can form an elastic structure with the mounting base 16 through the spring 17 and the connecting block 18.

[0023] In practical use, the connecting block 18 is moved by the toggle to cause the limiting plug 19 to retract. At this time, one end of the limiting plug 19 will disengage from the limiting slot 21, and then the protective baffle 15 can be flipped in the opposite direction.

[0024] Working principle: First, the support shaft is placed between the two connecting seats 12. Then, the second motor 8 drives the bidirectional lead screw 9 to rotate clockwise, causing the two threaded sleeves 10 connected to the outer wall to move the movable block 11 along the guide rod 14 towards each other. At the same time, the connecting bracket 22 at the top of the two threaded sleeves 10 will drive the two connecting seats 12 to move towards each other. After the two ends of the support shaft pass through the inside of the connecting seats 12, the two ends of the support shaft are fixed by tightening the locking bolts 13, thereby enabling bidirectional synchronous clamping of support shafts of different lengths. Then, the connecting block 18 is moved by the lever to drive the limit insert. Block 19 retracts, and then the protective baffle 15 is flipped to make it stand upright. At this time, by releasing the lever, the limiting insert 19 will pop out under the action of the spring 17 and insert into the limiting slot 21 on the top of the fixed block 20. Thus, the upright protective baffle 15 can protect the front of the device. At this time, the first motor 3 drives the lead screw 4 to rotate. The threaded connecting block 5 with its outer wall thread will drive the grinder 7 to move laterally along the guide slide. The electric telescopic rod 6 can control the grinding machine 7 to rise and fall, so that the rotating grinding wheel can contact the outer wall of the bottom fixed support shaft, thereby realizing the grinding process.

[0025] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
