Description

Technical Field

[0001] This invention relates to the field of universal joint processing equipment technology, and more specifically, to a universal joint processing apparatus and method. Background Technology

[0002] A universal joint, also known as a universal connector, is a key mechanical component for enabling transmission between different shafts at varying angles. A universal joint typically consists of a connecting body (universal joint fork), a connecting shaft, a bearing assembly, and seals. During the manufacturing process, an axial opening is usually machined into the inner wall of the universal joint fork. When the drive shaft or splined shaft is inserted and the locking bolts or nuts on both sides are tightened, the expansion joint is compressed and slightly contracts. Then, utilizing the elastic deformation of the material, the inner hole tightly encloses the shaft, achieving a zero-clearance interference fit. This ensures extremely high coaxiality between the shaft and the fork, preventing relative slippage during transmission.

[0003] Traditionally, the opening method for expansion joints in universal joints involves manually holding an angle grinder with one hand and the universal joint fork with the other, grinding an expansion joint along the axial direction of the second mounting hole on one side of the fork. However, due to individual differences, manually ground expansion joints are prone to skewing, resulting in poor cut consistency, affecting product yield, and severely impacting processing efficiency. Furthermore, manual hand-grinding poses certain safety hazards.

[0004] To address the aforementioned issues, some solutions have been proposed in the prior art. For example, Chinese utility model patent CN222552298U discloses a processing device for the expansion joint seam of a universal joint fork. This device uses a slider, a positioning tube, a tension spring, and a pushing head to clamp the universal joint fork. Then, the piston rod of the pushing cylinder moves the slider, positioning tube, tension spring, pushing head, and universal joint fork below the cutting part. The cutting disc then cuts an expansion joint seam into the universal joint fork, improving processing efficiency while reducing safety hazards. However, in actual processing, after the universal joint is processed, the operator needs to remove the processed universal joint before processing the next one, which seriously affects processing efficiency. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention aims to provide a universal joint processing device and method that can improve processing efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A universal joint processing device includes a processing table, an mounting ring rotatably mounted on the top wall of the processing table, mounting rods uniformly fixedly mounted on the mounting ring, a clamping assembly provided at the end of the mounting rod away from the mounting ring, and a cutting disc provided on the processing table;

[0008] The clamping assembly includes a mounting plate fixedly mounted on a mounting rod, a base plate fixedly mounted on the mounting plate, a sliding groove formed on the mounting plate, a side plate slidably mounted in the sliding groove, a clamping plate slidably mounted in the sliding groove, a first spring jointly mounted between the clamping plate and the side plate, and a second spring jointly mounted between the side plate and the sliding groove.

A drive assembly that cooperates with the mounting ring is provided on the horizontal plate.

[0009] Furthermore, the driving assembly includes a round rod fixedly installed on the bottom wall of the horizontal plate, and the round rod is slidably engaged with the mounting ring. The inner wall of the mounting ring is provided with an inclined groove and a vertical groove, and two adjacent inclined grooves are connected through the vertical groove. A protrusion that is slidably engaged with the vertical groove is fixedly installed on the round rod.

[0010] Furthermore, an inclined plate that mates with the inclined groove is rotatably installed in the vertical groove, a rotating rod that rotatably mates with the mounting ring is fixedly installed on the inclined plate, a spring is installed between the rotating rod and the mounting ring, a first limiting block is fixedly installed on the rotating rod, and a second limiting block that mates with the first limiting block is fixedly installed on the mounting ring.

[0011] Furthermore, the mounting rod has a cavity, a horizontal rod is slidably mounted in the cavity, and a return spring is installed between the horizontal rod and the cavity. A push plate is fixedly mounted on the horizontal rod. A conveyor belt is rotatably mounted on the processing table. A hollow rod is fixedly mounted on the top plate. A ring that rotates and seals with the mounting ring is fixedly mounted on the bottom wall of the hollow rod. A cavity communicating with the hollow rod is opened on the ring. A first air pipe communicating with the cavity is inserted into the cavity. A pressure relief pipe communicating with the first air pipe is fixedly mounted on the ring.

[0012] Furthermore, a guide tube is installed between the horizontal plate and the top plate, an air groove communicating with the guide tube is opened on the hollow rod, and an air inlet valve with an output end communicating with the guide tube is fixedly installed on the horizontal plate.

[0013] Furthermore, a processing groove is provided on the processing table, an electric telescopic rod is fixedly installed on the top wall of the processing table, a linkage plate that cooperates with the processing groove is fixedly installed on the output end of the electric telescopic rod, a connecting plate is fixedly installed on the linkage plate, and the cutting disc is rotatably installed on the connecting plate, and a motor whose output end is fixedly connected to the cutting disc is fixedly installed on the connecting plate.

[0014] Furthermore, the linkage plate is provided with a linkage block, a limit rod is horizontally slidably installed on the linkage block, a push block is fixedly installed at the end of the limit rod away from the linkage block, and a third spring is installed between the push block and the linkage block.

[0015] Furthermore, a collection box that mates with the processing tank is detachably installed on the bottom wall of the processing table. The collection box contains cutting fluid. A piston plate is vertically slidably installed inside the collection box. An inlet valve with its output end pointing downwards is fixedly installed on the piston plate. A drain valve is inserted into the collection box. A drain pipe is fixedly installed on the output end of the drain valve. A drain groove communicating with the drain pipe is opened on the limiting rod. A guide pipe communicating with the drain groove is fixedly installed on the push plate.

[0016] Furthermore, the linkage plate is provided with a linkage groove, and the linkage block is vertically slidably installed in the linkage groove. A threaded rod that is threadedly engaged with the linkage block is rotatably installed on the linkage plate, and a filter screen for filtering debris is installed in the collection box.

[0017] The present invention also provides a processing method applicable to the above-mentioned universal joint processing device, comprising the following steps:

[0018] S1. First, place the universal joint to be processed between the two clamping plates. When the output end of the electric push rod extends and drives the horizontal plate to move, the horizontal plate drives the clamping assembly to clamp and straighten the universal joint through the vertical rod.

[0019] S2. Start the motor to drive the cutting disc to rotate at high speed and extend the electric telescopic rod, thereby moving the cutting disc towards the universal joint until the cutting disc makes initial contact with the workpiece surface;

[0020] S3. During the movement of the horizontal plate, the piston plate is driven by the round rod to reciprocate in the collection box, so that the cutting fluid is transported to the drain pipe and sprayed through the drain tank and guide pipe to the assembly hole of the universal joint and the cutting edge of the cutting disc to achieve continuous cooling, lubrication and debris flushing.

[0021] S4. After processing, as the output end of the electric push rod retracts, it drives the horizontal plate to move upward. At the same time, the horizontal plate drives the round rod to move upward, and the protrusion slides into the inclined groove along the inclined plate, thereby driving the mounting ring and the mounting rod to rotate by a fixed angle.

[0022] S5. When the mounting rod with the finished product rotates to the conveyor belt, the high-pressure airflow in the guide tube enters the cavity through the hollow rod, and then enters the cavity through the first air pipe. The airflow pushes the horizontal rod to extend, which drives the push plate to push the finished universal joint off the bottom plate and smoothly slide into the conveyor belt.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] (1) This solution sets a first spring between the clamping plate and the side plate, and a second spring between the side plate and the slide groove. By utilizing the elastic buffer principle, it can adaptively clamp universal joint workpieces of different sizes and specifications without frequently changing the fixture, thus shortening the clamping auxiliary time. Moreover, through the cooperation of the inclined groove, vertical groove and protrusion, when the horizontal plate is reset and raised, it can not only drive the mounting ring to rotate through gear meshing, but also realize the automatic rotation of the workpiece without waiting for the unloading to be completed before loading, thus improving the processing efficiency.

[0025] (2) By setting a push plate, the airflow in the guide tube is compressed when the horizontal plate moves upward. When the mounting rod with the finished product rotates to the conveyor belt, the high-pressure airflow in the guide tube enters the cavity through the hollow rod and then enters the cavity through the first air pipe. The airflow pushes the horizontal rod to extend and drives the push plate to push the finished universal joint off the bottom plate, so that it can slide smoothly into the conveyor belt. There is no need for manual intervention to unload the material, which not only improves the processing efficiency, but also avoids the safety hazards caused by manual contact with sharp cutting surfaces.

[0026] (3) By setting up a piston plate, the piston plate is driven to squeeze the cutting fluid in the collection box during the movement of the horizontal plate, and then accurately transported to the contact point between the cutting disc and the workpiece through the liquid guide pipe. This achieves the effect of cooling and lubrication while processing, effectively reducing the working temperature of the cutting disc, removing processing debris, greatly extending the service life of the cutting disc, significantly improving processing efficiency, and ensuring the smoothness of the processed surface.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0047] Please see Figures 1 to 12 A universal joint processing device includes a processing table 101, an installation ring 102 rotatably mounted on the top wall of the processing table 101, an installation rod 103 uniformly fixedly mounted on the installation ring 102, a clamping component 2 provided at the end of the installation rod 103 away from the installation ring 102, and a cutting disc 104 provided on the processing table 101.

[0048] The clamping assembly 2 includes a mounting plate 201 fixedly mounted on a mounting rod 103. A base plate 202 is fixedly mounted on the mounting plate 201. A sliding groove is provided on the mounting plate 201. A side plate 203 is slidably mounted in the sliding groove. A clamping plate 204 is slidably mounted in the sliding groove. A first spring 205 is installed between the clamping plate 204 and the side plate 203. A second spring 207 is installed between the side plate 203 and the sliding groove. A support rod 208 is fixedly mounted on the top wall of the processing table 101. A top plate 209 is fixedly mounted on the top end of the support rod 208. An electric push rod 210 is fixedly mounted on the top plate 209. A horizontal plate 211 is fixedly mounted on the output end of the electric push rod 210. A vertical rod 212 is fixedly mounted on the bottom wall of the horizontal plate 211. The bottom end of the vertical rod 212 is inclined. A driving assembly 3 that cooperates with the mounting ring 102 is provided on the horizontal plate 211.

[0049] The drive assembly 3 includes a round rod 301 fixedly installed on the bottom wall of the horizontal plate 211, and the round rod 301 is slidably engaged with the mounting ring 102. The inner wall of the mounting ring 102 is provided with a slanted groove 302 and a vertical groove 303. Adjacent slanted grooves 302 are connected through the vertical groove 303. A protrusion 304 that is slidably engaged with the vertical groove 303 is fixedly installed on the round rod 301.

[0050] An inclined plate 305 that mates with an inclined groove 302 is rotatably installed inside the vertical groove 303. A rotating rod 306 that rotatably mates with an mounting ring 102 is fixedly installed on the inclined plate 305. A spring 307 is installed between the rotating rod 306 and the mounting ring 102. A first limiting block 308 is fixedly installed on the rotating rod 306. A second limiting block 309 that mates with the first limiting block 308 is fixedly installed on the mounting ring 102.

[0051] In use, the operator places the universal joint to be processed on the top wall of the base plate 202 located between the two clamping plates 204. Then, under the action of the drive assembly 3, the universal joint to be processed is moved to the cutting disc 104. At this time, the output end of the electric push rod 210 extends and drives the horizontal plate 211 to move downward. When the horizontal plate 211 moves downward, it drives the vertical rod 212 to move downward. During the downward movement of the vertical rod 212, the inclined surface of the vertical rod 212 gradually contacts the side plate 203 and pushes the two side plates 203 closer together. At this time, the second spring 207 is stretched and has a tendency to return to its original position. During the process of the two side plates 203 approaching each other, the side plates 203 drive the two clamping plates 204 to approach each other through the first spring 205, clamping the universal joint to be processed. Moreover, under the action of the elastic force of the first spring 205, universal joints of different sizes can be clamped, so that the operator does not need to change the clamping assembly 2. After clamping the universal joint, the cutting disc 104 can cut the universal joint. After processing, as the electric push rod 210 retracts, the drive assembly 3 will move the processed universal joint away from the cutting disc 104 and move the universal joint to be processed towards the cutting disc 104, which improves processing efficiency.

[0052] As the horizontal plate 211 moves downward, it drives the round rod 301 downward. As the round rod 301 moves downward, it drives the protrusion 304 downward along the vertical groove 303. Then, as the protrusion 304 moves downward, it gradually contacts the inclined plate 305 and applies a pushing force to it. Under the action of this pushing force, the inclined plate 305 drives the rotating rod 306 to rotate, at which point the spring 307 begins to store power. When the protrusion 304 disengages from the inclined plate 305, the spring 307 drives the inclined plate 305 to reset via the rotating rod 306. Then, as the horizontal plate 211 moves upward, it drives the vertical rod 212 upward and disengages from the side plate 203. At this point, the second spring 207 drives the side plate 203 to reset with the clamping plate 204. Simultaneously, as the horizontal plate 211 moves upward, it drives the protrusion 304 to move upward synchronously via the round rod 301. As the protrusion 304 moves upward, it gradually contacts the bottom wall of the inclined plate 305 and applies a pushing force to the bottom wall of the inclined plate 305. Since the first limiting block 308 and the second limiting block 309 are in contact at this time, the inclined plate 305 cannot rotate upward. Then, the protrusion 304 enters the inclined groove 302 along the bottom wall of the inclined plate 305 and moves upward along the inclined groove 302. During the sliding process of the protrusion 304 along the inclined plate 305 and the inclined groove 302, it drives the mounting ring 102 to rotate. When the mounting ring 102 rotates, it drives the mounting rod 103 to rotate. When the mounting rod 103 rotates, it drives the clamping assembly 2 to rotate, thereby automatically disengaging the universal joint that has finished processing from the cutting disc 104, and simultaneously driving the unprocessed universal joint to move towards the cutting disc 104. When the horizontal plate 211 returns to its upward reset position, the protrusion 304 enters the vertical groove 303 along the inclined groove 302, further improving processing efficiency.

[0053] like Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, the mounting rod 103 has a cavity 401, a horizontal rod 402 is slidably installed in the cavity 401, and a return spring 403 is installed between the horizontal rod 402 and the cavity 401. A push plate 404 is fixedly installed on the horizontal rod 402. A conveyor belt 405 is rotatably installed on the processing table 101. A hollow rod 406 is fixedly installed on the top plate 209. A ring 407 is fixedly installed on the bottom wall of the hollow rod 406, which is rotatably sealed with the mounting ring 102. A cavity 408 communicating with the hollow rod 406 is opened on the ring 407. A first air pipe 409 communicating with the cavity 408 is inserted into the cavity 401. A pressure relief pipe 410 communicating with the first air pipe 409 is fixedly installed on the ring 407.

[0054] A guide tube 411 is installed between the horizontal plate 211 and the top plate 209. An air groove 412 communicating with the guide tube 411 is opened on the hollow rod 406. An air inlet valve 413 whose output end is communicating with the guide tube 411 is fixedly installed on the horizontal plate 211.

[0055] By adopting the above technical solution, during the movement of the horizontal plate 211 driven by the electric push rod 210, the guide tube 411 can guide the horizontal plate 211, thereby ensuring the vertical movement of the horizontal plate 211. Then, during the downward movement of the horizontal plate 211, the closed volume formed by the relative sliding between the guide tube 411 and the horizontal plate 211 increases, generating negative pressure, and the guide tube 411 draws air from the outside through the air inlet valve 413; during the upward movement of the horizontal plate 211, the closed volume in the guide tube 411 decreases, the airflow is compressed to form a high-pressure airflow, and flows into the cavity 408 through the air groove 412 and the hollow rod 406. At the same time, the upward movement of the horizontal plate 211 will drive the mounting ring 102 to rotate, and the rotation of the mounting ring 102 will drive the first air pipe 409 to rotate. When the horizontal plate 211 reaches its highest point, the first air pipe 409 at the conveyor belt 405 connects to the cavity 408. Then, the airflow in the cavity 408 flows through the first air pipe 409 into the cavity 401, causing the horizontal rod 402 to slide along the cavity 401. At this time, the return spring 403 is stretched and tends to return to its original position. During the movement of the horizontal rod 402, the push plate 404 moves synchronously. During the movement of the push plate 404, the universal joint, after processing, moves onto the conveyor belt 405, thus eliminating the need for manual unloading and improving processing efficiency while preventing sharp burrs on the universal joint from cutting the user's hands.

[0056] like Figure 1 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, a processing groove 501 is provided on the processing table 101. An electric telescopic rod 502 is fixedly installed on the top wall of the processing table 101. A linkage plate 503 that cooperates with the processing groove 501 is fixedly installed on the output end of the electric telescopic rod 502. A connecting plate 504 is fixedly installed on the linkage plate 503, and the cutting disc 104 is rotatably installed on the connecting plate 504. A motor 505 whose output end is fixedly connected to the cutting disc 104 is fixedly installed on the connecting plate 504.

[0057] The linkage plate 503 is provided with a linkage block 506, and a limit rod 507 is horizontally slidably installed on the linkage block 506. A push block 508 is fixedly installed at the end of the limit rod 507 away from the linkage block 506, and a third spring 509 is installed between the push block 508 and the linkage block 506.

[0058] A collection box 510 that mates with the processing tank 501 is detachably installed on the bottom wall of the processing table 101. The collection box 510 contains cutting fluid. A piston plate 511 is vertically slidably installed inside the collection box 510. An inlet valve 512 with its output end pointing downwards is fixedly installed on the piston plate 511. A drain valve 518 is inserted into the collection box 510. A drain pipe 513 is fixedly installed on the output end of the drain valve 518. A drain groove 514 communicating with the drain pipe 513 is opened on the limiting rod 507. A guide pipe 515 communicating with the drain groove 514 is fixedly installed on the push plate 404.

[0059] The linkage plate 503 has a linkage groove, and the linkage block 506 is vertically slidably installed in the linkage groove. A threaded rod 516 that is threadedly engaged with the linkage block 506 is rotatably installed on the linkage plate 503. A filter screen 517 for filtering debris is installed in the collection box 510.

[0060] By adopting the above technical solution, when processing the universal joint, the user can control the extension of the output end of the electric telescopic rod 502. During the extension of the output end of the electric telescopic rod 502, it drives the linkage plate 503 to move towards the universal joint to be processed. During the movement of the linkage plate 503, the cutting disc 104 is driven to contact the universal joint through the connecting plate 504. At this time, the motor 505 drives the cutting disc 104 to rotate and process the universal joint, thus achieving the purpose of processing the universal joint.

[0061] As the round rod 301 moves upward, it drives the piston plate 511 to move upward synchronously. At this time, the space below the piston plate 511 in the collection box 510 draws cutting fluid from above the piston plate 511 through the inlet valve 512. Then, as the round rod 301 drives the piston plate 511 to move downward synchronously, the piston plate 511 will squeeze the cutting fluid below. Next, as the connecting plate 504 moves, it drives the linkage block 506 to move. During the movement of the linkage block 506, the third spring 509 drives the push block 508 to contact the universal joint, and the liquid guide pipe 515 is inserted into the assembly hole 6 on the universal joint that communicates with the expansion joint. At this time, the push block 508 can no longer move. As the linkage plate 503 drives the cutting disc 104 to cut the universal joint through the connecting plate 504, the push block 508 drives the limit rod 507 to slide along the linkage block 506. During the movement of the limit rod 507, it drives the drain groove 514 to connect with the drain pipe 513. At this time, the cutting fluid located below the piston plate 511 in the collection box 510 flows through the drain pipe 513 and drain trough 514 into the guide pipe 515, and then through the guide pipe 515 into the assembly hole 6, and then from the assembly hole 6 into the cutting disc 104. This improves cutting efficiency while extending the service life of the cutting disc 104. It should be noted that both the inlet valve 512 and the drain valve 518 are one-way valves with preset opening pressures; when the piston plate 511 moves upward to draw in fluid, the inlet valve 512 opens and the drain valve 518 closes; when the piston plate 511 moves downward to compress the cutting fluid to the opening pressure, the drain valve 518 opens and the inlet valve 512 closes. Furthermore, as the cutting fluid passes through the assembly hole 6, it can carry debris from the assembly hole 6 into the processing tank 501, and then through the processing tank 501 into the collection box 510. The filter screen 517 can filter the debris, further improving processing efficiency.

[0062] The user can adjust the height of the linkage block 506 by rotating the threaded rod 516, thereby adjusting the height of the liquid guide tube 515 to ensure that the liquid guide tube 515 can enter the assembly hole 6 normally.

[0063] The present invention also provides a processing method applicable to the above-mentioned universal joint processing device, comprising the following steps:

[0064] S1. First, place the universal joint to be processed between the two clamping plates 204. When the output end of the electric push rod 210 extends and drives the horizontal plate 211 to move, the horizontal plate 211 drives the clamping assembly 2 to clamp and straighten the universal joint through the vertical rod 212.

[0065] S2. Start motor 505 drives cutting disc 104 to rotate at high speed and extends electric telescopic rod 502, thereby driving cutting disc 104 to move in the direction of universal joint until cutting disc 104 initially contacts the surface of workpiece.

[0066] S3. During the movement of the horizontal plate 211, the piston plate 511 is driven by the round rod 301 to reciprocate in the collection box 510, so that the cutting fluid is transported to the drain pipe 513 and sprayed through the drain groove 514 and the guide pipe 515 to the assembly hole 6 of the universal joint and the cutting edge of the cutting disc 104 to achieve continuous cooling, lubrication and debris flushing.

[0067] S4. After processing, as the output end of the electric push rod 210 retracts, it drives the horizontal plate 211 to move upward. At the same time, the horizontal plate 211 drives the round rod 301 to move upward, and the protrusion 304 slides into the inclined groove 302 along the inclined plate 305, thereby driving the mounting ring 102 together with the mounting rod 103 to rotate by a fixed angle.

[0068] S5. When the mounting rod 103 with the finished product rotates to the conveyor belt 405, the high-pressure airflow in the guide tube 411 enters the cavity 408 through the hollow rod 406, and then enters the cavity 401 through the first air pipe 409. The airflow pushes the horizontal rod 402 to extend, which drives the push plate 404 to push the finished universal joint off the bottom plate 202 and smoothly slide into the conveyor belt 405.

[0069] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
