Description

Technical Field

[0001] This invention belongs to the technical field of tooth cutting devices, and specifically relates to a tooth cutting table device. Background Technology

[0002] The existing method for cutting teeth on the cylindrical surface of ring-shaped parts is to place the ring-shaped part vertically on a mold, manually operate a press to close the mold, cut teeth on the cylindrical surface, and after cutting one tooth, manually rotate the ring to cut the next tooth.

[0003] In existing technologies, the following problems exist when cutting multiple teeth into ring-shaped parts: The operation heavily relies on the skills and experience of the operators. Parts processed by different batches and by different operators exhibit significant dimensional fluctuations, tooth profile errors, and large angular deviations between tooth pitches, failing to meet the sealing and connection precision requirements of the rings. This results in a low product yield, slow manual feeding and positioning speeds, and long processing times for single pieces, making it unsuitable for mass production needs and significantly limiting capacity. Furthermore, operators are required to perform repetitive, monotonous actions for extended periods, leading to fatigue, further impacting processing accuracy, and resulting in high labor costs. Summary of the Invention

By incorporating a positioning component, the device automatically clamps and positions the workpiece and fixture before tooth cutting, improving the positioning accuracy of the workpiece and ensuring that subsequent assembly and connection accuracy meet requirements. Furthermore, when multiple teeth need to be cut on a cylindrical surface, the automated program controls the processing flow. After the first tooth is cut, the clamping component releases, and the servo motor rotates the workpiece and fixture together by a predetermined angle before clamping them again, automatically cutting the second tooth. The actions are smooth and continuous, ensuring consistent tooth height and shape, thus improving production efficiency.

[0009] Furthermore, the cutting tooth assembly includes: A cutting tooth holder is fixedly installed on the mounting base plate, and a cutting tooth punch is installed at one end of the cutting tooth holder.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] A tooth-cutting platform device, such as Figures 1-3 As shown, it includes: Install base plate 1; A drive assembly mounted on the mounting base plate 1; The toothed assembly 2 is connected to the drive assembly for transmission; The positioning component 3 for fixing the workpiece 12 to be processed is disposed at the end of the cutting tooth component 2 away from the driving component; And a clamping assembly 4, which is used to clamp the workpiece 12 to be processed onto the positioning assembly 3; The drive component is used to drive the cutting tooth component 2 to process the workpiece 12 to be processed.

[0021] According to a specific embodiment provided by the present invention, such as Figure 6 As shown, the workpiece 12 to be processed in this invention is mainly a ring-shaped part. The mounting base plate 1 is a rectangular plate structure. A drive component is installed at one end of the upper surface of the mounting base plate 1, and a positioning component 3 is installed at the other end of the upper surface of the mounting base plate 1. A cutting tooth component 2 is installed at the output end of the drive component to process the workpiece 12.

[0022] This invention achieves automatic clamping and positioning of the workpiece 12 and the tooling before tooth cutting by setting the positioning component 3, thereby improving the tooth cutting positioning accuracy of the workpiece 12 and ensuring that the subsequent assembly and connection accuracy meets the requirements. At the same time, when the workpiece 12 needs to cut multiple teeth on the cylindrical surface, the automated program controls the processing flow. After the workpiece 12 cuts the first tooth, the clamping component 4 is released, and the servo motor 36 drives the part and the tooling to rotate by a specified angle and then be clamped again, and then automatically cuts the second tooth. The action is smooth and continuous, and the height and tooth shape of the cut teeth are consistent, thus improving production efficiency.

[0023] The clamping component 4 achieves positioning and clamping of the workpiece 12 before cutting, preventing misalignment and movement. In mass production, the part size deviation is minimal, the assembly compatibility is greatly improved, and the subsequent rework rate is reduced. Operators only need to set parameters and monitor equipment operation, which greatly reduces labor intensity and avoids safety hazards in manual processing.

[0024] Furthermore, such as Figure 4 As shown, the positioning assembly 3 includes a rotary mounting plate 31, a rotary support gear 32, an indexing plate 33, a positioning flange 34, and a rotary drive component. The rotary mounting plate 31 is slidably mounted on the mounting base plate 1 via a buffer assembly 39. The rotary support gear 32 is mounted on the rotary mounting plate 31, and the indexing plate 33 is mounted on the upper part of the rotary support gear 32. The positioning flange 34 is mounted on the upper part of the indexing plate 33 and is used to place the workpiece 12 to be processed. The rotary support gear 32 is in a transmission cooperation with the rotary drive component, and the rotary drive component is used to drive the rotary support gear 32 to rotate the positioning flange 34.

[0025] According to a specific embodiment of the present invention, the rotary mounting plate 31 is a rectangular plate structure with an area smaller than that of the sliding base plate 391. The inner ring of the rotary support gear 32 is fixedly mounted on the rotary mounting plate 31 below it by annularly distributed fasteners. The outer ring of the rotary support gear 32 is fixedly mounted on the indexing plate 33 above it by annularly distributed fasteners. The indexing plate 33 is annular in structure, and a positioning flange 34 is provided above the indexing plate 33. The positioning flange 34 has a raised annular structure in the middle. The raised annular structure fits against the annular inner wall of the workpiece 12 to be processed. The workpiece 12 to be processed is pressed onto the positioning flange 34 by the clamping assembly 4. The rotary drive component drives the rotary support gear 32 to rotate, so that the workpiece 12 to be processed on the positioning flange 34 rotates.

[0026] This invention achieves automatic clamping and positioning of the workpiece 12 and the tooling before tooth cutting by setting the positioning component 3. This improves the positioning accuracy of the tooth cutting of the workpiece 12 and ensures that the subsequent assembly and connection accuracy meets the requirements. At the same time, when the workpiece 12 needs to cut multiple teeth on the cylindrical surface, the automated program controls the processing flow. After the workpiece 12 cuts the first tooth, the clamping component 4 is released, and the driving component drives the workpiece 12 and the tooling to rotate as a whole by a specified angle before being clamped again by the clamping component 4. Then the second tooth is automatically cut. The action is smooth and continuous, and the height and tooth shape of the cut teeth are consistent, which greatly improves the production efficiency.

[0027] By setting up a positioning component 3, the present invention enables automatic rotation, clamping and cutting of the workpiece 12 when multiple teeth need to be cut in the circumferential direction, without the need for manual rotation of the parts, thereby improving the accuracy and efficiency of tooth cutting and increasing the pass rate of the workpiece 12.

[0028] Furthermore, the rotary drive component includes a motor mounting plate 35, a servo motor 36, a transmission gear 37, and a reducer component 38. The reducer component 38 is connected to the servo motor 36 in a transmission manner. The servo motor 36 is mounted on the motor mounting plate 35 through the reducer component 38. The transmission gear 37 is connected to the reducer component 38 in a transmission manner, and the transmission gear 37 meshes with the rotary support gear 32.

[0029] This embodiment provides a specific structure for a rotary drive component. Specifically, a mounting base plate 1 has a hole, and a servo motor 36 is positioned perpendicular to the mounting base plate 1 and passes through the hole. A motor mounting plate 35 is fixed to a sliding base plate 391. When the sliding base plate 391 slides, the hole does not restrict the movement of the servo motor 36. A transmission gear 37 is connected to a reducer component 38, and the height of the transmission gear 37 is greater than that of the motor mounting plate 35. The transmission gear 37 meshes with a rotary support gear 32, which is a pinion and a large gear. To protect the rotary support gear 32 and the transmission gear 37, a large gear cover is provided on the outside of the rotary support gear 32, and a small gear cover is provided on the outside of the transmission gear 37.

[0030] Furthermore, the buffer assembly 39 includes a sliding base plate 391 fixed to the rotary mounting plate 31, a spring seat 392, a compression spring 393, a spring guide post, and a linear module 394. The mounting base plate 1 is equipped with two linear modules 394. The sliding base plate 391 is slidably connected to the mounting base plate 1 through the linear modules 394. Two spring seats 392 are fixed on both sides of the mounting base plate 1. One end of the spring guide post is fixed to the side of the sliding base plate 391, and the other end extends into the hole of the spring seat 392. The compression spring 393 is sleeved on the spring guide post. One end of the compression spring 393 contacts the spring seat 392, and the other end contacts the side of the sliding base plate 391. The installation direction of the compression spring 393 is consistent with the sliding direction of the sliding base plate 391.

[0031] According to a specific embodiment of the present invention, the buffer component 39 is disposed between the positioning component 3 and the mounting base plate 1. The function of the buffer component 39 is to provide displacement function for the positioning component 3 when the cutting die 25 moves and abuts against the outer wall of the workpiece 12 to be processed. At the same time, it can also automatically return the positioning component 3 to its original position, so that the workpiece 12 to be processed can wait for the next cutting.

[0032] Specifically, the rotary mounting plate 31, the sliding base plate 391, and the mounting base plate 1 are arranged parallel to each other. Two spring seats 392 are respectively arranged at the corners of the sliding base plate 391. The spring seats 392 are located on the side of the sliding base plate 391 away from the drive assembly. The linear module 394 is located between the sliding base plate 391 and the mounting base plate 1. The linear modules 394 are arranged parallel to each other, and the setting direction of the linear modules 394 is located in the length direction of the mounting base plate 1.

[0033] Spring seat 392 is used to install compression spring 393. Spring seat 392 can be fixed to linear module 394. The other end of linear module 394 extends out of sliding base plate 391. Limit plate 395 is fixed to this end of linear module 394. Limit plate 395 is used to prevent sliding base plate 391 from disengaging from linear module 394. Compression spring 393 is sleeved on spring guide post. One side of spring guide post is fixed to the side of sliding base plate 391, and the other end extends into the hole of spring seat 392. One end face of compression spring 393 contacts spring seat 392, and the other end face contacts the side of sliding base plate 391, so that when compression spring 393 is compressed, it can push sliding base plate 391 back to its original position, thereby causing sliding base plate 391 to drive positioning component 3 and then drive workpiece 12 to return to its original position.

[0034] Furthermore, such as Figure 5 As shown, the cutting tooth assembly 2 includes: A cutting tooth seat 21 is fixedly installed on the mounting base plate 1. A cutting tooth punch 22 is installed at one end of the cutting tooth seat 21. The cutting tooth punch 22 is located inside the positioning component 3. Guide post and guide sleeve component 23 is installed on the cutting tooth seat 21; The transverse pusher 24 is connected to the cutting tooth seat 21 via the guide post and guide sleeve component 23; A cutting die 25 is fixedly installed at one end of the transverse push block 24, and the cutting die 25 is disposed opposite to the cutting punch 22; and A connecting component 26 is installed on the cutting tooth seat 21. The connecting component 26 is located at one end of the cutting tooth seat 21 away from the cutting tooth punch 22. The connecting component 26 is used to connect the transverse push block 24 to the drive component. The cutting die 25 can move along the cutting seat 21 to approach or move away from the cutting punch 22 under the restriction of the guide post and guide sleeve component 23.

[0035] According to a specific embodiment of the present invention, a cutting tooth holder 21 is fixedly mounted on a mounting base plate 1, located between a positioning component 3 and a driving component. A cutting tooth punch 22 is a plate structure with an arc-shaped convex surface at one end. The cutting tooth punch 22 is vertically fixed to the cutting tooth holder 21 via a punch seat 221. The height of the punch seat 221 is set according to the height of the positioning component 3, allowing the cutting tooth punch 22 to extend into the workpiece 12 to be processed. A cutting tooth die 25 is fixedly mounted on the end of a transverse push block 24 near the cutting tooth punch 22. The cutting tooth die 25 is a plate structure with a corresponding cutting tooth shape at one end, and the arc-shaped convex surface corresponds to the shape of the workpiece 12 to be processed. A cutting tooth groove is formed on the side of the cutting tooth die 25 near the cutting tooth punch 22. The cutting tooth die 25 and the cutting tooth punch 22 have the same height, and the cutting tooth groove can accommodate the cutting tooth punch 22 when it moves and cuts teeth.

[0036] The guide post and guide sleeve components 23 are arranged parallel to the linear module 394. There are two guide post and guide sleeve components 23, and they are parallel to each other. Specifically, two parallel guide post plates are formed on the cutting tooth base 21. The guide post plates are vertically fixed on the cutting tooth base 21, and guide posts are fixed between the guide post plates. Guide sleeves are fitted on the guide posts. In this way, the cutting tooth die 25 can move towards the cutting tooth punch 22 under the drive of the drive assembly.

[0037] The upper part of the guide post and guide sleeve component 23 is fixed to the transverse push block 24. The transverse push block 24 is set horizontally. A connecting component 26 is installed at the end of the transverse push block 24 away from the cutting die 25. The connecting component 26 connects and separates the drive component and the cutting component 2, thereby facilitating the removal and replacement of the workpiece 12 to be processed.

[0038] Further, the connecting assembly 26 includes: a cylinder plate 261, a slide cylinder 262, a tail mounting plate 263, and a pin plate 264. The cylinder plate 261 is fixed to the output end of the drive assembly. The slide cylinder 262 is mounted on the cylinder plate 261. The slide cylinder 262 is vertically arranged. The pin plate 264 is mounted on the output end of the slide cylinder 262. The tail mounting plate 263 is mounted on the end of the transverse push block 24. This allows the slide cylinder 262 to drive the pin plate 264 to engage with the tail mounting plate 263 after it operates.

[0039] Furthermore, connecting grooves 265 are respectively provided on both sides of the pin plate 264, and the tail plate 263 has an overall "L" shaped structure. There are two tail plates 263, which are respectively fixed on both sides of the transverse push block 24. Specifically, the tail plate 263 is located at the end of the transverse push block 24 away from the cutting tooth die 25. The tail plate 263 is set corresponding to the pin plate 264, and the end of the tail plate 263 can be inserted into the connecting groove 265 opened in the pin plate 264.

[0040] According to a specific embodiment of the present invention, this embodiment provides a specific structure of the connecting component 26. The cylinder plate 261 is vertically fixed to the output end of the drive component, and the slide cylinder 262 is vertically disposed on one side of the cylinder plate 261. After the slide cylinder 262 works, it can drive the pin plate 264 at the output end to move up and down. Specifically, after the pin plate 264 moves up, it disengages from the tail hanging plate 263, so that the workpiece 12 to be processed of the positioning component 3 can be easily removed. After the pin plate 264 moves down, it connects with the tail hanging plate 263, so that the power energy of the drive component is transmitted to the cutting component 2.

[0041] Furthermore, the drive assembly includes a booster cylinder 11 mounted on the mounting base plate 1. The booster cylinder 11 is mounted on the mounting base plate 1 via a drive seat 111. The cylinder plate 261 is mounted on the output end of the booster cylinder 11. The installation direction of the booster cylinder 11 is consistent with that of the guide post and guide sleeve component 23.

[0042] The number of in-situ detection components 13 is two sets, one set is installed on the sliding base plate 391 and the other set is installed on the mounting base plate 1. The in-situ detection components 13 include a bracket 131 installed on the sliding base plate 391 and the mounting base plate 1 and an infrared detector 132 installed on the bracket 131.

[0043] Furthermore, the clamping assembly 4 includes a rotary clamping cylinder 41, a cylinder connecting shaft 42, and a clamping swing arm 43 mounted on the mounting base plate 1. The output end of the rotary clamping cylinder 41 is fixed to the cylinder connecting shaft 42, which passes through the clamping swing arm 43. The clamping swing arm 43 has an overall "L" shaped structure and a clamping plate parallel to the mounting base plate 1. A clamping buffer pad is provided on the side of the clamping plate facing the mounting base plate 1.

[0044] In actual production, the workpiece 12 is not clamped to the positioning fixture before tooth cutting, resulting in misalignment and inaccurate positioning, and the cut teeth have large burrs on the edges. When manually cutting multiple teeth, the contact area between the workpiece 12 and the positioning fixture needs to be moved multiple times, and the workpiece 12 needs to be stabilized manually before tooth cutting without a clamping device, which will cause misalignment and inaccurate positioning, and the height of the cut teeth will be unstable.

[0045] In this embodiment, a specific structure of the clamping component 4 is provided, which realizes the positioning and clamping of the workpiece 12 before cutting, preventing misalignment and movement. The part size deviation is minimal in mass production, the assembly compatibility is greatly improved, and the subsequent rework rate is reduced. Operators only need to set parameters and monitor the operation of the equipment, which greatly reduces the labor intensity and avoids the safety hazards in manual processing.

[0046] The specific working process of the tooth cutting table device of the present invention is as follows: The automatic clamping and tooth cutting process of the part is as follows: The rotary clamping cylinder 41 drives the clamping swing arm 43 to rotate, clamping the workpiece 12 to be processed installed on the positioning flange 34. After the position detection component 13 detects that the product is in the correct position, the piston rod of the booster cylinder 11 extends, pushing the connecting component 26 towards the positioning component 3. At this time, the transverse push block 24 in the connecting component 26 that pushes the tooth cutting component 2 moves, driving the front tooth cutting die 25 to move. When the tooth cutting die 25 moves, the outer cylindrical surface of the workpiece 12 to be processed comes into contact with the arc surface of the tooth cutting die 25 and is also squeezed forward, driving the sliding base plate 391 to move together, squeezing the compression spring 393 on the spring seat 392, and the spring stores energy. When the tooth cutting die 25 pushes the part to the point where the tooth cutting punch 22 comes into contact with the inner cylindrical surface of the workpiece 12 to be processed, the tooth cutting die 25 and the tooth cutting punch 22 close and squeeze the side wall of the workpiece 12 to be processed, and then the workpiece 12 to be processed is cut with teeth. After the teeth are cut, the piston rod of the booster cylinder 11 retracts, causing the tail plate 263 mounted on the transverse push block 24 to move backward. The cutting die 25 retracts, and the cutting punch 22 separates from the cutting die 25, completing the first cutting action.

[0047] After the first tooth is cut, the rotary clamping cylinder 41 drives the clamping swing arm 43 to rotate in the opposite direction, releasing the clamped workpiece 12. The compression spring 393 returns to its original deformation, causing the sliding base plate 391 and the positioning flange 34 mounted on the sliding base plate 391, along with the workpiece 12, to retract to their pre-cutting position. The servo motor 36 rotates at a set angle, driving the transmission gear 37 to rotate. The rotary support gear 32, meshing with the transmission gear 37, also rotates, causing the indexing plate 33 and the positioning flange 34 mounted on the indexing plate 33, along with the workpiece 12, to rotate at a specified angle and then stop. At this point, the rotary clamping cylinder 41 drives the clamping swing arm 43 to rotate, clamping the workpiece 12 mounted on the positioning flange 34, and begins cutting the next tooth.
