Description

Technical Field

[0001] This application belongs to the field of bicycle technology, specifically relating to a jack and its processing equipment. Background Technology

[0002] Currently, the flywheel structure commonly used in electric bicycles and high-end bicycles involves a jack with a spring coil mounted on the core. When the outer casing rotates clockwise, the spring springs up, and the jack engages with the ratchet teeth on the outer casing. When the outer casing rotates counterclockwise, the ratchet teeth press down on the jack, causing the core to detach from the outer casing and spin freely. Since electric bicycles primarily operate in this free-spinning state with the core detached from the outer casing, the prolonged friction between the spring coil and the ratchet teeth can easily cause the spring coil to wear down and break, leading to flywheel failure. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the purpose of this application is to provide a jack that smoothly transitions between the end of the spring groove away from the jack teeth and the jack block, changing the original point contact between the spring ring and the jack block to a surface contact. This significantly reduces the pressure on the spring ring, thereby reducing the friction of the spring ring in the spring groove, reducing the wear of the spring ring, and extending the service life of the flywheel.

[0004] The technical solution adopted by this application to solve the above-mentioned technical problems is as follows: a jack is provided, comprising: a jack block and a jack tooth integrally connected, the jack block being disposed in the jack groove of the core, the jack tooth engaging with the ratchet of the inner hole of the outer sleeve, the jack being provided with a spring groove penetrating the jack block and the jack tooth, the spring groove being used to install a spring coil, the spring groove penetrating the jack tooth radially, and the end of the spring groove away from the jack tooth smoothly transitioning to the jack block.

[0005] Through the above technical features, since the end of the spring groove away from the jack tooth has a smooth transition with the jack block, the original point contact between the spring ring and the jack block is changed to a surface contact, which significantly reduces the pressure on the spring ring, thereby reducing the friction of the spring ring in the spring groove, reducing the wear of the spring ring, and extending the service life of the flywheel.

[0006] Preferably, the end of the jack near the spring groove has an arc-shaped curved surface.

[0007] Through the aforementioned technical features, the arc-shaped curved surface can reduce friction and wear between the jack and the spring ring, making the contact between the curved surface and the spring ring more uniform, reducing local stress, thereby reducing the wear rate and extending the service life of the flywheel.

[0008] This application also provides the aforementioned processing equipment for the heavy pound, including: a processing table; A feeding mechanism is slidably connected to the processing table, and the feeding mechanism is used to feed the material tube of the processing jack; A clamping mechanism is disposed on one side of the feeding mechanism and located on the processing table. The clamping mechanism is used to clamp the material tube conveyed by the feeding mechanism. A cutting mechanism is disposed on one side of the clamping mechanism and slidably connected to the processing table. The cutting mechanism is used to cut off the material tube at the clamping mechanism to form the integrally connected jack block and jack teeth, and to cut the spring groove on the cut integrally connected jack block and jack teeth. A chamfering mechanism is disposed on one side of the clamping mechanism and slidably connected to the processing table. The chamfering mechanism is used to chamfer the cut integrally connected jack block and jack teeth, so that the end of the spring groove away from the jack teeth smoothly transitions with the jack block.

[0009] With the above technical features, during use, the material tube to be processed is slidably fed into the processing table by the feeding mechanism, ensuring that the material tube enters the processing area at a stable speed and position; when the material tube reaches the predetermined position, the clamping mechanism will be activated to firmly clamp the material tube on the processing table, ensuring that the material tube remains stable during subsequent processing and preventing movement or deviation; then the cutting mechanism moves along the preset cutting path to cut the material tube, cutting it into a jack block and jack teeth that are connected as a whole. At the same time, the cutting mechanism will also cut spring grooves on the cut jack block and jack teeth; then the chamfering mechanism slides along the processing table to chamfer the cut jack block and jack teeth, so that the end of the spring groove away from the jack teeth transitions smoothly with the jack block, thereby reducing stress concentration and improving the durability of the spring coil.

[0010] Therefore, the processing equipment for jacks in this application achieves efficient, precise and automated processing of jacks by integrating feeding, clamping, cutting and chamfering mechanisms, thereby improving product quality and production efficiency, reducing costs and increasing operational flexibility.

[0011] Preferably, the feeding mechanism includes: a feeding plate slidably connected to the processing table, a feeding groove connected to the lower end of the feeding plate, a feeding slider provided on the processing table, the feeding slider extending toward the clamping mechanism, and the feeding groove cooperating with the feeding slider; A feeding cylinder is connected to one side of the feeding plate, and the feeding cylinder pushes the feeding plate to move back and forth along the feeding slider; A feeding clamp is disposed on the side of the feeding plate near the clamping mechanism. The feeding clamp shown is used to clamp the material tube during feeding.

[0012] Through the aforementioned technical features, the feeding cylinder pushes the feeding plate back and forth along the feeding slider, ensuring the stability and accuracy of the feeding process. Therefore, the cooperation between the feeding plate, the feeding chute, and the feeding slider, along with the stable drive of the feeding cylinder, ensures the stability of the feeding process, reduces vibration and deviation of the material tube during feeding, and improves processing accuracy. Furthermore, the feeding fixture can accurately clamp the material tube, preventing it from moving or deviating during feeding, ensuring that the material tube can be accurately fed into the clamping mechanism for subsequent processing, thus achieving stable and accurate feeding.

[0013] Preferably, the feeding fixture includes a lower template, an upper template, and a clamping cylinder. The lower template is connected to the feeding plate, and the upper end of the lower template is provided with a lower placement groove. The upper template is rotatably connected to the feeding plate, and the lower end of the upper template is provided with an upper placement groove. The lower placement groove and the upper placement groove are combined to form a clamping groove. The shape of the clamping groove is adapted to the shape of the material tube. The clamping cylinder is connected to the upper end of the upper template on the side away from the upper placement groove. The clamping cylinder is used to drive the upper template to rotate relative to the lower template, thereby realizing the combination and separation of the lower placement groove and the upper placement groove.

[0014] With the above technical features, during feeding, the operator places the material tube to be processed in the lower placement slot. Then, the clamping cylinder drives the upper template to rotate relative to the lower template. As the upper template rotates, the upper placement slot gradually approaches the lower placement slot and eventually merges with it to form a complete clamping slot. The shape of the clamping slot matches the shape of the material tube, ensuring the material tube is stably fixed within the clamping slot. After the clamping slot clamps the material tube, the feeding plate, driven by the feeding cylinder, moves along the feeding slider towards the clamping mechanism, delivering the material tube to the clamping mechanism for subsequent processing. After processing is completed, the clamping cylinder drives the upper template to rotate away from the lower template, opening the clamping slot. Then, the feeding cylinder drives the feeding plate along the feeding slider away from the clamping mechanism, returning to its initial position for easy feeding again. Therefore, by combining the upper and lower placement slots, a clamping slot that matches the shape of the material tube is formed, which can stably fix the material tube and prevent it from shaking or shifting during feeding, thus improving processing accuracy. Furthermore, by using the clamping cylinder to drive the rotation of the upper template, the clamping slot can be opened and closed automatically, enabling reciprocating feeding processing without manual operation, thereby improving automation and production efficiency.

[0015] Preferably, the clamping mechanism includes a first clamping block, a second clamping block, and a clamping cylinder. The first clamping block has a first clamping groove penetrating the first clamping block on the side near the second clamping block, and the second clamping block has a second clamping groove penetrating the second clamping block on the side near the first clamping block. The clamping cylinder is connected to one side of the first clamping block and is used to drive the first clamping block to move closer to or further away from the second clamping block. When the first clamping block moves to the side near the second clamping block, the first clamping groove and the second clamping groove are combined to form a total clamping groove. The formation of the total clamping groove is adapted to the shape of the material tube. The feeding mechanism feeds the material tube into the first clamping groove and the second clamping groove.

[0016] Through the aforementioned technical features, when the feeding mechanism feeds the material tube into the area between the first and second clamping grooves, the clamping cylinder drives the first clamping block to move closer to the second clamping block. When the first clamping block moves close enough, the first and second clamping grooves merge into a complete overall clamping groove. The overall clamping groove matches the shape of the material tube, tightly surrounding and fixing the material tube, thus achieving the clamping function and ensuring the stability of the material tube during processing, preventing it from moving or shifting. When processing is completed and the next jack needs to be used, the clamping cylinder drives the first clamping block to move away from the second clamping block, facilitating the entry of the material tube fed by the feeding mechanism into the area between the first and second clamping grooves.

[0017] Preferably, the upper ends of the first clamping block and the second clamping block are provided with a first clearance groove and a second clearance groove that are arranged in parallel and pass through the first clamping block and the second clamping block. The depth of the second clearance groove is less than that of the first clearance groove. The first clearance groove is used to make clearance when the cutting mechanism cuts the material tube, and the second clearance groove is used to make clearance when the cutting mechanism cuts the spring groove and when the chamfering mechanism makes chamfers.

[0018] Through the aforementioned technical features, when the cutting mechanism performs tube cutting, the first clearance groove provides sufficient space to prevent interference with the clamping block; when the cutting mechanism cuts the spring groove, the second clearance groove provides necessary clearance space to ensure smooth cutting. Similarly, when the chamfering mechanism performs chamfering, the second clearance groove also provides sufficient clearance space to prevent collision with the clamping block. Therefore, by setting the first and second clearance grooves, interference between the cutting and chamfering mechanisms and the clamping block during processing is effectively avoided, thus ensuring the continuity and efficiency of the processing. Moreover, the depth difference design of the first and second clearance grooves allows the clamping mechanism to adapt to the clearance requirements of different processing stages, improving its adaptability and flexibility.

[0019] Preferably, the cutting mechanism includes a mounting plate, a cutting cylinder, a first gear, a second gear, and a cutting motor. The cutting motor, the first gear, and the second gear are all connected to the mounting plate. The cutting cylinder drives the mounting plate to move back and forth along the extension direction parallel to the first and second clearance grooves. The first gear and the second gear are coaxially connected, and the diameter of the second gear is smaller than that of the first gear. The cutting motor drives the first gear and the second gear to rotate. The first gear is positioned in the extension direction of the first clearance groove, and the second gear is positioned in the extension direction of the second clearance groove. The first gear is used to cut the material tube at the first clearance groove, and the second gear is used to cut and form the spring groove at the second clearance groove.

[0020] Through the aforementioned technical features, when the material tube needs to be cut, the cutting cylinder drives the mounting plate to move, causing the first gear to move to the first clearance groove. The cutting motor drives the first gear to rotate and cut the material tube, while the second gear moves to the second clearance groove. The cutting motor simultaneously drives the second gear to rotate and cut, forming a spring groove. Because the diameters of the first and second gears are different, the cutting depths are different, facilitating synchronous rotation of the first and second gears. The first gear cuts the material tube, while the second gear cuts the spring groove on the tube. Therefore, the cutting mechanism of this application, through the driving of the cutting cylinder, the transmission of the gears, and the cooperation with the clearance groove, achieves efficient and high-precision cutting of the material tube and fine cutting of the spring groove. It has a compact structure and is simple to operate.

[0021] Preferably, the chamfering mechanism includes a third gear and a chamfering motor. Both the third gear and the chamfering motor are connected to the mounting plate. The chamfering motor is used to drive the third gear to rotate. The third gear is arranged in the extension direction of the second clearance groove. The third gear is used to chamfer the end of the spring groove away from the jack tooth at the second clearance groove, so that the end of the spring groove away from the jack tooth and the jack block transition smoothly.

[0022] With the aforementioned technical features, after the material tube is cut into the spring groove by the cutting mechanism, the chamfering mechanism begins to operate. The chamfering motor starts, driving the third gear to rotate at the second clearance groove. The third gear chamfers the end of the spring groove furthest from the jack teeth, creating a smooth transition between that end and the jack block. The chamfering process eliminates the sharp edges of the spring groove, preventing wear between the spring groove and the spring ring during subsequent use, thus improving product safety and reliability. Furthermore, the chamfering mechanism shares a mounting plate with the cutting mechanism, simplifying the equipment structure and making the entire processing smoother, thereby increasing production efficiency.

[0023] Preferably, a cooling pipe is also connected to the processing table. The cooling pipe is located above the cutting mechanism and the chamfering mechanism. Coolant flows inside the cooling pipe, which is used to cool the cutting mechanism and the chamfering mechanism.

[0024] Through the aforementioned technical features, the cutting and chamfering mechanisms generate a significant amount of heat during operation due to friction and cutting with the feed tube. The cooling effect of the cooling pipe on the cutting and chamfering mechanisms prevents them from being damaged due to overheating, thereby extending the service life of the equipment. Furthermore, the cooled cutting and chamfering mechanisms maintain a stable processing state, avoiding deformation or errors caused by excessive temperature, and improving processing accuracy.

[0025] In summary, this application has the following beneficial effects: (1) By setting the end of the spring groove away from the jack tooth to make a smooth transition between the spring groove and the jack block, the point contact between the original spring ring and the jack block is changed to a surface contact, which significantly reduces the pressure on the spring ring, thereby reducing the friction of the spring ring in the spring groove, reducing the wear of the spring ring, and extending the service life of the flywheel. (2) This application achieves efficient, precise and automated processing of the jack by integrating feeding, clamping, cutting and chamfering mechanisms, which improves product quality and production efficiency, reduces costs and increases operational flexibility.

[0028] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0029] Example 1: like Figure 1 As shown, this embodiment 1 discloses a jack, including: a jack block 11 and a jack tooth 12 integrally connected, the jack block 11 is disposed in the jack groove of the core, and the jack tooth 12 engages with the ratchet of the inner hole of the outer sleeve.

[0030] The jack 1 is provided with a spring groove 13 that passes through the jack block 11 and the jack tooth 12, and the spring groove 13 passes through the jack tooth 12 radially. The spring groove 13 is used to install the spring ring. The end of the spring groove 13 away from the jack tooth 12 transitions smoothly with the jack block 11. Specifically, the end of the jack block 11 near the spring groove 13 is provided with an arc-shaped curved surface 14.

[0031] Working principle: The jack 1 is placed in the jack groove of the core. The spring groove 13 passes through the jack block 11 and the jack tooth 12, which makes it easier for the spring ring to be installed more stably on the jack 1. The spring groove 13 passes through the jack tooth 12 radially, so that the spring ring is pressed on the end of the jack block 11 away from the jack tooth 12.

[0032] The end of the spring groove 13 away from the jack tooth 12 is smoothly connected to the jack block 11 by the arc-shaped curved surface 14, which changes the original point contact between the spring ring and the jack block 11 to a surface contact. This significantly reduces the pressure on the spring ring, thereby reducing the friction of the spring ring in the spring groove 13, reducing the wear of the spring ring, and extending the service life of the flywheel.

[0033] Example 2: like Figure 2 As shown, this embodiment 2 discloses the processing equipment for the jack of embodiment 1, including: a processing table 2, on which a feeding mechanism 3, a clamping mechanism 4, a cutting mechanism 5, and a chamfering mechanism 6 are provided. A protective cover 23 is provided on the outer periphery of the processing table 2. The feeding mechanism 3, the clamping mechanism 4, the cutting mechanism 5, and the chamfering mechanism 6 are all arranged inside the protective cover 23. The protective cover 23 protects the feeding mechanism 3, the clamping mechanism 4, the cutting mechanism 5, and the chamfering mechanism 6, and also protects the operator to avoid accidental injury to the operator during processing.

[0034] The protective cover 23 is provided with a feeding port 231, through which the material tube 7 enters the feeding mechanism 3. The feeding mechanism 3 is slidably connected to the processing table 2 and is used to transport the material tube 7 to the clamping mechanism 4. The clamping mechanism 4 is located on one side of the feeding mechanism 3 and is used to clamp the material tube 7 transported by the feeding mechanism 3 to prevent the material tube 7 from moving during subsequent processing. The cutting mechanism 5 is located on one side of the clamping mechanism 4 and is slidably connected to the processing table 2. The cutting mechanism 5 is used to cut the material tube 7 at the clamping mechanism 4 to form an integrally connected jack block 11 and jack teeth 12. At the same time, a spring groove 13 is cut on the cut integrally connected jack block 11 and jack teeth 12. The chamfering mechanism 6 is located on one side of the clamping mechanism 4 and is slidably connected to the processing table 2. The chamfering mechanism 6 is used to chamfer the cut integrally connected jack block 11 and jack teeth 12 so that the end of the spring groove 13 away from the jack teeth 12 transitions smoothly with the jack block 11, thus completing the processing of the jack 1.

[0035] In this application, a protective door 232 is also provided on the side of the protective cover 23 opposite to the feed port 231, so that the staff can open the protective cover 23 to carry out operations inside the processing when needed.

[0036] In this application, a cooling pipe 22 is also connected to the processing table 2. The cooling pipe 22 is located above the cutting mechanism 5 and the chamfering mechanism 6. Coolant flows in the cooling pipe 22 to cool down the cutting mechanism 5 and the chamfering mechanism 6, ensuring a stable processing state for the cutting mechanism 5 and the chamfering mechanism 6, avoiding deformation or errors caused by excessive temperature, and improving processing accuracy.

[0037] like Figure 3As shown, the feeding mechanism 3 in this application includes a feeding plate 31, a feeding cylinder 32, and a feeding fixture 33.

[0038] The lower end of the feeding plate 31 is connected to the feeding chute 311, and the processing table 2 is provided with the feeding slider 21. The feeding chute 311 and the feeding slider 21 cooperate with each other. The feeding cylinder 32 is connected to one side of the feeding plate 31 and is used to push the feeding plate 31 to move back and forth along the feeding slider 21. The feeding clamp 33 is connected to the side of the feeding plate 31 near the clamping mechanism 4 and is used to clamp the material tube 7 during feeding.

[0039] During feeding, the operator places the material tube 7 to be processed into the feeding fixture 33, which clamps the material tube 7. Then, the feeding cylinder 32 pushes the feeding plate 31 and the feeding fixture 33 on the feeding plate 31 to move closer to the clamping mechanism 4, feeding the material tube 7 held by the feeding fixture 33 into the clamping mechanism 4. After that, the feeding fixture 33 releases its grip on the material tube 7, and the feeding cylinder 32 drives the feeding plate 31 and the feeding fixture 33 to return to their initial positions. During the return process, the material tube 7 is clamped at the clamping mechanism and will not return with the feeding mechanism 3. After the material tube 7 is processed by the cutting mechanism 5 and the chamfering mechanism 6 at the clamping mechanism, the feeding mechanism 3 feeds the material tube 7 back into the clamping mechanism 4 for the next round of processing. This process is repeated to complete the feeding of the material tube 7.

[0040] In this application, in order to facilitate the installation of the feeding cylinder 32, a placement slot 24 is provided on the processing table 2, and the feeding cylinder 32 is placed in the placement slot 24, which effectively utilizes the space of the processing table 2 and makes the entire equipment structure more compact.

[0041] In this application, in order to facilitate the movement of the material tube 7 along with the feeding mechanism 3, a support block 25 is provided on the worktable near the feeding port 231. The support block 25 is provided with a support groove 251. The shape of the support groove 251 matches the shape of the material tube 7, and the height of the support block 25 is consistent with the height of the feeding fixture 33, so that the material tube 7 can smoothly transition from the support groove 251 to the feeding fixture 33 without additional adjustment or operation, thereby simplifying the feeding process and improving production efficiency.

[0042] like Figure 3 , Figure 4 As shown, the feeding fixture 33 in this application includes a lower template 331, an upper template 332, and a fixture cylinder 333.

[0043] The lower template 331 is connected to the feeding plate 31. The upper end of the lower template 331 is provided with a lower placement groove 334. The upper template 332 is rotatably connected to the feeding plate 31. The lower end of the upper template 332 is provided with an upper placement groove 335. The lower placement groove 334 and the upper placement groove 335 are combined to form a clamping groove 336. The shape of the clamping groove 336 matches the shape of the material tube 7. The clamping cylinder 333 is connected to the upper end of the upper template 332 on the side away from the upper placement groove 335. The telescopic rod of the clamping cylinder 333 passes through the upper template 332 and is connected to the feeding plate 31. The clamping cylinder 333 is used to drive the upper template 332 to rotate relative to the lower template 331, thereby realizing the combination and separation of the lower placement groove 334 and the upper placement groove 335.

[0044] During feeding, the operator places the material tube 7 to be processed in the lower placement groove 334. Then, the clamping cylinder 333 drives the upper template 332 to rotate relative to the lower template 331. As the upper template 332 rotates, the upper placement groove 335 gradually approaches the lower placement groove 334 and finally merges with the lower placement groove 334 to form a complete clamping groove 336. The shape of the clamping groove 336 matches the shape of the material tube 7, ensuring that the material tube 7 is stably fixed in the clamping groove 336. Then, the feeding cylinder 32 pushes the feeding plate 31 and the feeding clamp 33 to move.

[0045] After processing one jack 1, before the feeding cylinder 32 drives the feeding plate 31 and the feeding fixture 33 to return, the clamping cylinder 333 drives the upper template 332 to move away from the lower template 331, the clamping slot 336 opens, and then the feeding plate 31 and the feeding fixture 33 return to their initial positions. During the return process, the material tube 7 will not be driven to return together.

[0046] In this application, during the rotation of the upper template 332 driven by the clamp cylinder 333, in order to reduce the impact and vibration caused by direct collision between the extension rod of the clamp cylinder 333 and the feeding plate 31, a buffer spring 337 is connected between the extension rod of the clamp cylinder 333 and the feeding plate 31. The buffer spring 337 can absorb the kinetic energy of the clamp cylinder 333 and convert it into a rebound force, which plays a buffering role when the clamp cylinder 333 retracts or the upper template 332 moves in the opposite direction.

[0047] like Figure 5 , Figure 6 As shown, the clamping mechanism 4 of this application includes a first clamping block 41, a second clamping block 42, and a clamping cylinder 43.

[0048] The first clamping block 41 has a first clamping groove 411 that passes through it on the side near the second clamping block 42. The second clamping block 42 has a second clamping groove 421 that passes through it on the side near the first clamping block 41. A clamping cylinder 43 is connected to one side of the first clamping block 41 and is used to move the first clamping block 41 closer to or further away from the second clamping block 42. When the first clamping block 41 moves to the side near the second clamping block 42, the first clamping groove 411 and the second clamping groove 421 merge to form a total clamping groove 44. The total clamping groove 44 is formed to match the shape of the material tube 7 and is used to clamp the material tube 7.

[0049] During feeding, the feeding mechanism 3 delivers the material tube 7 into the area of ​​the first clamping groove 411 and the second clamping groove 421. The clamping cylinder 43 drives the first clamping block 41 to move closer to the second clamping block 42. When the first clamping block 41 moves close enough, the first clamping groove 411 and the second clamping groove 421 combine to form a complete total clamping groove 44. The total clamping groove 44 tightly surrounds and fixes the material tube 7, achieving the clamping function and ensuring that the material tube 7 remains stable during processing, preventing it from moving or shifting. When processing is completed and the next jack 1 needs to be processed, the clamping cylinder 43 drives the first clamping block 41 to move away from the second clamping block 42, so that the material tube 7 delivered by the feeding mechanism 3 can enter the area of ​​the first clamping groove 411 and the second clamping groove 421. Then, the material tube 7 is clamped again for processing.

[0050] In this application, to facilitate the movement of the first clamping block 41, a clamping slider 412 is provided at the lower end of the first clamping block 41, and a clamping groove 26 is provided on the processing table 2. Through the cooperation of the clamping slider 412 and the clamping groove 26, the movement of the first clamping block 41 is guided, ensuring that when the first clamping block 41 moves to the second clamping block 42, the first clamping groove 411 and the second clamping groove 421 cooperate to form a closed total clamping groove 44, thereby achieving the clamping of the material tube 7.

[0051] In this application, after the clamping mechanism 4 clamps the material tube 7, both the cutting mechanism 5 and the chamfering mechanism 6 cut and chamfer the material tube 7 at the clamping mechanism 4. Therefore, in this application, a first clearance groove 45 and a second clearance groove 46 are provided at the upper end of the first clamping block 41 and the second clamping block 42 in parallel arrangement. The depth of the second clearance groove 46 is less than that of the first clearance groove 45. The first clearance groove 45 is used to make clearance when the cutting mechanism 5 cuts the material tube 7, and the second clearance groove 46 is used to make clearance when the cutting mechanism 5 cuts the spring groove 13 and when the chamfering mechanism 6 makes chamfers.

[0052] In this application, after the material tube 7 at the clamping mechanism 4 is processed by the cutting mechanism 5 and the chamfering mechanism 6 to form the jack 1, when the material tube 7 is processed again to form the next jack 1, the clamping cylinder 43 of the clamping mechanism 4 will drive the first clamping block 41 to move away from the second clamping block 42. At this time, the waste material generated during the processing of the jack 1 and the cutting in the clamping mechanism 4 enters the collection box 28 located on one side of the processing table 2 through the guide pipe 27 at the lower end of the clamping mechanism 4, making room for the feeding of the next jack 1 and facilitating automatic and continuous production processing of the equipment. In this application, the guide pipe 27 is located below the clamping mechanism 4 and is connected to the main clamping groove 44.

[0053] like Figure 7 As shown, the cutting mechanism 5 in this application includes a mounting plate 51, a cutting cylinder 52, a first gear 53, a second gear 54, and a cutting motor 55.

[0054] The cutting motor 55, the first gear 53, and the second gear 54 are all connected to the mounting plate 51. The cutting cylinder 52 is used to drive the mounting plate 51 to move back and forth along the extension direction parallel to the first clearance groove 45 and the second clearance groove 46. The first gear 53 and the second gear 54 are coaxially connected. The diameter of the second gear 54 is smaller than that of the first gear 53. The cutting motor 55 is used to drive the first gear 53 and the second gear 54 to rotate. The first gear 53 is set in the extension direction of the first clearance groove 45, and the second gear 54 is set in the extension direction of the second clearance groove 46. The first gear 53 is used to cut the material tube 7 at the first clearance groove 45, and the second gear 54 is used to cut and form the spring groove 13 at the second clearance groove 46.

[0055] When the material tube 7 needs to be cut, the cutting cylinder 52 drives the mounting plate 51 to move, causing the first gear 53 to move to the first clearance groove 45. The cutting motor 55 drives the first gear 53 to rotate and cut the material tube 7. At the same time, the second gear 54 moves to the second clearance groove 46, and the cutting motor 55 simultaneously drives the second gear 54 to rotate and cut to form the spring groove 13. Because the diameters of the first gear 53 and the second gear 54 are different, the cutting depths are different, which facilitates the synchronous rotation and cutting of the first gear 53 and the second gear 54. When the first gear 53 cuts the material tube 7, the second gear 54 cuts the spring groove 13 on the material tube 7.

[0056] In order to facilitate the movement of the mounting plate 51, a slide groove 511 is provided at the lower end of the mounting plate 51, and a slider 29 is provided on the processing table 2. The slide groove 511 and the slider 29 cooperate to guide the movement of the mounting plate 51 and ensure the stability of the movement of the mounting plate 51.

[0057] The chamfering mechanism 6 in this application includes a third gear 61 and a chamfering motor 62. Both the third gear 61 and the chamfering motor 62 are connected to the mounting plate 51. The chamfering motor 62 is used to drive the third gear 61 to rotate. The third gear 61 is arranged in the extension direction of the second clearance groove 46. The third gear 61 is used to chamfer the end of the spring groove 13 away from the jack tooth 12 at the second clearance groove 46, so that the end of the spring groove 13 away from the jack tooth 12 transitions smoothly with the jack block 11.

[0058] In this application, the chamfering mechanism 6 and the cutting mechanism 5 share the same mounting plate 51, which simplifies the equipment structure and makes the entire processing process smoother and improves production efficiency.

[0059] Working principle: During use, the material tube 7 to be processed is slidably fed into the processing table 2 by the feeding mechanism 3, ensuring that the material tube 7 enters the processing area at a stable speed and position; when the material tube 7 reaches the predetermined position, the clamping mechanism 4 will be activated to firmly clamp the material tube 7 on the processing table 2, ensuring that the material tube 7 remains stable during subsequent processing and preventing movement or deviation; then the cutting mechanism 5 moves along the preset cutting path to cut the material tube 7, cutting the material tube 7 into a jack block 11 and jack teeth 12 connected as one piece. At the same time, the cutting mechanism 5 will also cut spring grooves 13 on the cut jack block 11 and jack teeth 12; then the chamfering mechanism 6 slides along the processing table 2 to chamfer the cut jack block 11 and jack teeth 12, so that the end of the spring groove 13 away from the jack teeth 12 transitions smoothly with the jack block 11, so as to reduce stress concentration, improve the durability of the spring coil, and complete the processing of the jack 1.

Those skilled in the art to which this application pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the scope defined in this application.
