Description

Technical Field

[0001] This utility model belongs to the field of stud processing technology, specifically a stud embossing integrated processing device. Background Technology

[0002] Studs are commonly used fasteners in the field of mechanical connections and are widely used in industries such as automobiles, electronics, and construction machinery. To enhance the anti-slip performance, anti-loosening effect, or decorative properties of the stud surface, it is often necessary to perform embossing to create regular patterns on the stud surface.

[0003] Chinese Patent Application No. 202420340850.5 discloses a knurling device for stud production, including a worktable. A clamping and rotating mechanism is provided on the top of the worktable. This mechanism includes a slide groove, with a slide rail fixedly connected inside the groove. A motor bracket is movably connected to the outer wall of the slide rail. This clamping and rotating mechanism automatically clamps, rotates, and moves the stud. During use, two first electric push rods are activated to clamp the stud, a motor is started to rotate the clamped stud, and a second electric push rod is activated to move the stud. This avoids the risk of injury caused by manual operation, ensuring the safety of the equipment, eliminating potential safety hazards, and increasing its working efficiency.

[0004] However, the above-mentioned knurling equipment for stud production has the following shortcomings in actual use: 1. It adopts a step-by-step process of "clamping and then feeding", which requires multiple manual or additional mechanisms to complete the positioning and conveying of studs. The process is cumbersome and has poor connection, resulting in low processing efficiency and making it difficult to adapt to large-scale production scenarios; 2. It lacks a cleaning structure for the knurling cutter. Metal shavings generated during the embossing process are easy to adhere to the surface of the knurling cutter, which not only reduces the processing accuracy of the knurling pattern and affects the embossing quality of the stud, but also aggravates the wear of the knurling cutter and shortens its service life.

[0005] Therefore, a stud embossing integrated processing device is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an integrated stud knurling processing device, which has the advantages of automatically completing stud feeding, knurling, and unloading, adapting to studs of different specifications, and cleaning the knurling cutter in real time to ensure processing accuracy and tool life.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an integrated stud embossing processing device, comprising a worktable, on which a spacing adjustment component arranged in the front-to-back direction is installed on the left side, and two knurling components arranged symmetrically in the front-to-back direction are connected to the top of the spacing adjustment component. The knurling components are located above the worktable, and a cleaning component is connected to the knurling components. A pushing component is arranged on the right side of the knurling components, and a matching unloading component is arranged below the pushing component.

[0008] Preferably, the spacing adjustment assembly includes two fixed plates arranged symmetrically front to back, with a worktable fixedly connected to the top of the fixed plates. A bidirectional lead screw is provided between the fixed plates, and two threads with opposite directions are provided on the outer surface of the bidirectional lead screw. One end of the bidirectional lead screw is connected to the corresponding fixed plate through a bearing, and the other end passes through the corresponding fixed plate and is connected to a first motor. The bidirectional lead screw is threadedly connected to two threaded sleeves that are symmetrical front to back and move in opposite directions, and a connecting plate is fixedly connected to the top of the threaded sleeves.

[0009] Preferably, a limiting groove is provided on the worktable at a position corresponding to the connecting plate, and the connecting plate passes through the limiting groove.

[0010] Preferably, the knurling assembly includes a movable base fixedly connected to the top of the connecting plate at its bottom, a second motor mounted on the movable base, and a knurling cutter connected to the output end of the second motor via a motor shaft, the two knurling cutters rotating in opposite directions.

[0011] Preferably, the cleaning assembly includes an arc-shaped brush located below the knurling blade, the bristles of the arc-shaped brush contacting the outer surface of the knurling blade, a positioning slot being provided on the movable seat at a position corresponding to the arc-shaped brush, the end of the arc-shaped brush extending into the positioning slot, a first magnet plate being embedded in the bottom inner wall of the positioning slot, and a second magnet plate being fixed on the arc-shaped brush at a position corresponding to the first magnet plate.

[0012] Preferably, the feeding assembly includes a stand fixedly connected to the top of the workbench. The stand is connected to a lead screw and a guide rod, and a third motor is connected to one end of the lead screw that passes through the stand. The third motor is mounted on the stand. A displacement block is connected between the lead screw and the guide rod. A feeding plate is fixedly connected to the bottom of the displacement block. A reset feeding plate with an L-shaped structure is connected to the left side of the feeding plate. A support plate is slidably attached to the feeding plate. The position of the support plate corresponds to the position of the knurling cutter. The bottom of the support plate is connected to the workbench via a stand.

[0013] Preferably, the lead screw is threadedly connected to the displacement block, the guide rod passes through the displacement block, and the support plate is composed of two sections, which are located on the left and right sides of the knurling cutter, respectively.

[0014] Preferably, the feeding assembly includes a guide plate, a baffle is provided at the discharge end of the guide plate, an airbag is provided on the inner side of the baffle, and a discharge channel is provided at the bottom of the discharge end of the guide plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The pusher assembly of this utility model, through the cooperation of the reset pusher plate and the support plate, allows the stud to be stably placed in the space between the two and fall on the support plate. During processing, the pusher plate can accurately push the stud to the knurling position to ensure the knurling positioning accuracy. After knurling is completed, the reset pusher plate can push the stud back and out of the support plate, so that it falls onto the guide plate. The whole process does not require additional clamping or transfer mechanism, realizing the continuous operation of stud "feeding-knurling-unloading", which simplifies the process, improves the processing efficiency, avoids the error of multi-process connection, and ensures the consistency of stud processing.

[0017] 2. The cleaning component of this utility model adopts a design where an arc-shaped brush contacts the outer surface of the knurling cutter. At the same time, with the magnetic attraction of the first and second magnetic plates, the end of the arc-shaped brush is firmly inserted into the positioning slot of the moving base. This structure can not only remove metal debris generated during the knurling process in real time, avoiding debris accumulation that affects the processing accuracy of the knurling pattern, but also facilitate the quick disassembly and assembly of the arc-shaped brush. When the brush bristles are worn or require deep cleaning, they can be easily replaced or cleaned, thereby maintaining the cleanliness and processing performance of the knurling cutter, indirectly extending the service life of the knurling cutter, and ensuring the stability of the stud embossing quality.

[0029] 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.

[0030] like Figures 1 to 5 As shown, this utility model provides an integrated stud embossing processing device, including a worktable 1. A spacing adjustment component 2 is installed on the left side of the worktable 1, arranged in the front-to-back direction. The spacing adjustment component 2 can flexibly adjust the spacing between two knurling components 3 to adapt to the embossing requirements of studs of different specifications, improving the versatility of the equipment. Two knurling components 3 are symmetrically arranged front-to-back on the top of the spacing adjustment component 2. The knurling components 3 are located above the worktable 1. A cleaning component 4 is connected to the knurling components 3. The cleaning component 4 can remove metal debris from the surface of the knurling cutter 33 in real time, avoiding the debris from affecting the embossing accuracy, and facilitating the cleaning and maintenance of the knurling cutter 33. A pusher component 5 is arranged on the right side of the knurling components 3. The pusher component 5 can automatically complete the feeding of the stud, reset and unload after embossing, simplifying the process and improving processing efficiency. A matching unloading component 6 is arranged below the pusher component 5. The unloading component 6 can buffer, guide and collect the unloaded studs to prevent collision damage.

[0031] Specifically, the spacing adjustment component 2 includes two symmetrically arranged fixed plates 21. The top of the fixed plates 21 is fixedly connected to the worktable 1. A bidirectional lead screw 22 is arranged between the fixed plates 21. The outer surface of the bidirectional lead screw 22 is provided with two threads with opposite directions. One end of the bidirectional lead screw 22 is connected to the corresponding fixed plate 21 through a bearing, and the other end passes through the corresponding fixed plate 21 and is connected to a first motor 23. When the first motor 23 drives the bidirectional lead screw 22 to rotate, it can drive the two threaded sleeves 24 to move synchronously in opposite directions, thereby accurately and conveniently adjusting the spacing of the two knurled components 3, improving the adjustment accuracy and operating efficiency. The bidirectional lead screw 22 is threadedly connected to two symmetrically arranged threaded sleeves 24 with opposite directions of movement. A connecting plate 25 is fixedly connected to the top of the threaded sleeves 24.

[0032] Furthermore, a limiting groove 26 is provided on the workbench 1 at the position corresponding to the connecting plate 25. The connecting plate 25 passes through the limiting groove 26. The limiting groove 26 plays a limiting and guiding role in the movement of the connecting plate 25, ensuring the stability of the threaded sleeve 24 driving the knurled assembly 3 to move and avoiding deviation.

[0033] Furthermore, the knurling assembly 3 includes a movable base 31 fixedly connected to the top of the connecting plate 25 at its bottom. A second motor 32 is mounted on the movable base 31. The output end of the second motor 32 is connected to a knurling cutter 33 through a motor shaft. The two knurling cutters 33 rotate in opposite directions. The knurling cutters 33 rotating in opposite directions can make the force more even when the stud is embossed, and the embossed texture is more regular, effectively improving the embossing quality.

[0034] It is worth noting that the cleaning component 4 includes an arc-shaped brush 41 located below the knurling blade 33. The bristles of the arc-shaped brush 41 contact the outer surface of the knurling blade 33. When the knurling blade 33 rotates, the arc-shaped brush 41 can clean the metal debris attached to its surface in real time, preventing the accumulation of debris from affecting the accuracy of the texture. A positioning slot 42 is provided on the moving base 31 at the position corresponding to the arc-shaped brush 41. The end of the arc-shaped brush 41 extends into the positioning slot 42. A first magnet plate 43 is embedded in the bottom inner wall of the positioning slot 42. A second magnet plate 44 is fixed on the arc-shaped brush 41 at the position corresponding to the first magnet plate 43. Through the magnetic attraction between the first magnet plate 43 and the second magnet plate 44, the stability of the arc-shaped brush 41 is ensured, and it is easy to quickly disassemble and assemble, which is convenient for subsequent cleaning or replacement of the bristles.

[0035] It is worth noting that the feeding assembly 5 includes a stand 51 fixedly connected to the top of the workbench 1. The stand 51 is connected to a lead screw 52 and a guide rod 53. A third motor 54 is connected to one end of the lead screw 52 that passes through the stand 51. The third motor 54 is mounted on the stand 51. A displacement block 55 is connected between the lead screw 52 and the guide rod 53. When the third motor 54 drives the lead screw 52 to rotate, the displacement block 55 can move stably along the guide rod 53, ensuring the linear accuracy of the feeding. A feeding plate 56 is fixedly connected to the bottom of the displacement block 55. On the left side, there is an L-shaped reset push plate 57. The push plate 56 slides against the support plate 58. The stud can be stably placed on the support plate 58 through the space between the reset push plate 57 and the support plate 58. The push plate 56 can accurately push the stud to the knurling position. After the knurling is completed, the reset push plate 57 can push the stud back and out of the support plate 58, realizing automatic feeding and unloading. No additional clamping mechanism is required, which greatly simplifies the process. The position of the support plate 58 corresponds to the position of the knurling knife 33. The bottom of the support plate 58 is connected to the worktable 1 through the upright.

[0036] It is worth mentioning that the lead screw 52 is threadedly connected to the displacement block 55, the guide rod 53 passes through the displacement block 55, and the support plate 58 is composed of two sections. The two sections of the support plate 58 are located on the left and right sides of the knurling cutter 33, respectively. This segmented design reserves space for the knurling operation of the knurling cutter 33, and at the same time facilitates the stable placement and pushing of the stud on the support plate 58.

[0037] It is worth emphasizing that the feeding assembly 6 includes a guide plate 61, a baffle 62 is provided at the discharge end of the guide plate 61, and an airbag 63 is provided on the inner side of the baffle 62. When the stud falls from the support plate 58 to the guide plate 61, the airbag 63 can buffer the stud and prevent the stud from being damaged by the collision. A discharge channel 64 is provided at the bottom of the discharge end of the guide plate 61 to facilitate the collection of studs and improve the convenience of unloading.

[0038] Among them, the first motor 23, the second motor 32, and the third motor 54 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0039] Working principle and process: First, according to the specifications of the stud to be processed, the first motor 23 in the spacing adjustment assembly 2 is started, driving the bidirectional lead screw 22 to rotate. This causes the threaded sleeve 24 with opposite thread direction on the outer surface to drive the connecting plate 25 to move in the opposite or same direction along the limiting through groove 26, thereby adjusting the spacing of the knurling cutters 33 in the two knurling assemblies 3 to match the stud size. Then, the stud is placed on the support plate 58 of the pusher assembly 5, and is located in the space formed by the reset pusher plate 57 and the support plate 58. The third motor 54 is started to drive the lead screw 52 to rotate. The displacement block 55 moves along the guide rod 53 and drives the pusher plate 56 to precisely place the stud. The stud is pushed to the embossing position between the two knurling cutters 33. Then, the second motor 32 in the knurling assembly 3 is started, which drives the two knurling cutters 33 to rotate in opposite directions to emboss the stud. At the same time, the arc-shaped brush 41 of the cleaning assembly 4 cleans the metal debris on the surface of the stud as the knurling cutters 33 rotate. After the embossing is completed, the third motor 54 reverses, the displacement block 55 drives the pusher plate 56 to move back, and the reset pusher plate 57 pushes the stud back and pushes it out of the support plate 58. The stud falls onto the guide plate 61 of the feeding assembly 6. After being buffered by the airbag pad 63 inside the baffle, it is collected from the discharge channel 64. This completes the single stud embossing process.
