Description

Technical Field

[0001] This application relates to the technical field of automotive parts processing equipment, and in particular to an automatic post-processing equipment for composite leaf spring products. Background Technology

[0002] Composite leaf springs are widely used in automotive chassis suspension systems. Compared with traditional metal leaf springs, they are lighter, have a longer fatigue life, and are more durable.

[0003] Currently, such as Figure 1 The composite leaf spring body (hereinafter referred to as "leaf spring body") is mainly formed in one piece using the prepreg compression molding (PCM) process. After the leaf spring body is formed, it also needs to undergo multiple post-processing steps such as end cutting and trimming, and drilling to meet the requirements of subsequent assembly and use.

[0004] The cutting and trimming process involves removing burrs from both ends of the leaf spring body using cutting equipment. The drilling process involves drilling holes at the ends of the leaf spring body using drilling tools to provide an assembly base for the subsequent installation of the upper and lower clamping plates. At the same time, in order to eliminate stress concentration on the outer edges of the leaf spring and improve the fatigue life of the leaf spring body, all four edges of the leaf spring body, including the top and bottom edges, need to be chamfered. The chamfering of the bottom edge of the leaf spring can be formed simultaneously during the molding process through the internal drafting structure of the mold. However, the two edges at the top of the leaf spring are limited by the molding process conditions and cannot be formed simultaneously with the body. Therefore, a secondary chamfering process is performed after the leaf spring body is formed using chamfering equipment.

[0005] Regarding the post-processing technology of the aforementioned composite leaf springs, the industry currently requires multiple machines to complete the processes such as end trimming, drilling, and chamfering in stages. On the one hand, the multi-machine step-by-step processing makes the overall post-processing process relatively cumbersome and the processing flow long. On the other hand, during the connection between each post-processing process, the leaf spring body needs to be disassembled, transported, and positioned, which is relatively inconvenient and difficult to adapt to the needs of large-scale mass production. Therefore, there is room for improvement. Summary of the Invention

[0006] To improve the post-processing efficiency of the leaf spring body, this application provides an automatic post-processing equipment for composite leaf spring products.

[0007] This application provides an automatic post-processing equipment for composite leaf spring products, which adopts the following technical solution: An automated post-processing equipment for composite leaf spring products includes a cutting and drilling mechanism, a chamfering mechanism, and a transfer mechanism; The cutting and drilling mechanism includes a cutting and drilling frame, which is equipped with a first clamping fixture and a cutting and drilling assembly. The first clamping fixture is used to clamp the leaf spring body. The cutting and drilling assembly includes two cutting and drilling robotic arms, which are located on both sides of the first clamping fixture. A cutting machine and a drilling machine are mounted on the cutting and drilling robotic arms. The cutting and drilling robotic arms are used to cooperate with the cutting machine to cut and trim the ends of the leaf spring body, and are also used to cooperate with the drilling machine to drill holes in the ends of the leaf spring body. The chamfering mechanism includes a chamfering frame, on which a second clamping fixture and a chamfering assembly are provided. The second clamping fixture is used to clamp the leaf spring body. The chamfering assembly is located close to the second clamping fixture. The chamfering assembly includes a chamfering robotic arm and a chamfering drill. The chamfering robotic arm is used to cooperate with the chamfering drill to chamfer the top edge of the leaf spring body. The transfer mechanism is located near the cutting and drilling mechanism and the chamfering mechanism, and the transfer mechanism is used to transfer the leaf spring body located in the first clamping fixture to the second clamping fixture.

[0008] By adopting the above technical solution, after the leaf spring body is clamped by the first clamping fixture, the cutting and drilling robots located on both sides of the first clamping fixture, together with the corresponding cutting machine and drilling machine, successively complete the cutting and trimming and drilling of the two ends of the leaf spring. Then, the leaf spring body that has completed the cutting, trimming and drilling processes is transferred to the second clamping fixture of the chamfering mechanism through the transfer mechanism. After being clamped by the second clamping fixture, the chamfering robot, together with the chamfering drilling machine, completes the chamfering of the two edges at the top of the leaf spring. Compared with the traditional mode of processing in steps by multiple machines, the cutting, trimming and drilling can be processed in a centralized manner, which effectively simplifies the post-processing process and shortens the processing flow. At the same time, the transfer of the leaf spring body between the cutting and drilling process and the chamfering process can be automatically connected by the transfer mechanism, without the need for manual repeated disassembly, reassembly, transfer and positioning of the leaf spring body, which effectively improves the post-processing efficiency of the leaf spring body.

[0009] Preferably, the drilling frame is further provided with a first clamping drive; the first clamping drive is used to drive the first clamping fixture to move toward or away from the drilling assembly; The chamfering frame is also provided with a second clamping drive; the second clamping drive is used to drive the second clamping fixture to move toward or away from the chamfering assembly.

[0010] By adopting the above technical solution, when clamping or disassembling the leaf spring body, the first clamping drive member and the second clamping drive rod can respectively drive the first processing clamping fixture and the second clamping common fixture away from the processing position, which facilitates the clamping and disassembly of the leaf spring body in a larger space, effectively avoiding interference and collision between the leaf spring body and the cutting and drilling components and chamfering components during the clamping and disassembly process, and reducing the operational difficulty of the clamping and disassembly process of the leaf spring body.

[0011] Preferably, the drilling robot arm includes an X-axis moving module, a Y-axis moving module, a connecting arm, and a Z-axis moving module; The Y-axis moving module is mounted on the moving end of the X-axis moving module, the connecting arm is vertically mounted on the moving end of the Y-axis moving module, and the Z-axis moving module is mounted on the top of the connecting arm; The cutting machine is mounted on the connecting arm; The drilling rig is installed on the moving end of the Z-axis moving module.

[0012] By adopting the above technical solution, the cutting and drilling robotic arm uses a multi-axis linkage structure with X, Y, and Z axis moving modules. When cutting and trimming the leaf spring body, the X and Y axis moving modules, in conjunction with the connecting arm, drive the cutting machine to move along the two-dimensional direction to complete the cutting and trimming of the leaf spring end. When drilling the leaf spring body, the X and Y axis moving modules, in conjunction with the connecting arm, drive the drilling machine to the corresponding drilling position on the leaf spring body, and the Z axis moving module drives the drilling machine to feed and reset to complete the drilling process of the leaf spring body. Both cutting and drilling processes can be completed by the cutting and drilling robotic arm without changing the processing parts, effectively improving the connection efficiency of cutting and drilling processes.

[0013] Preferably, the Z-axis moving module is horizontally rotatably connected to the top of the connecting arm, and the connecting arm is provided with a first rotary drive component corresponding to the Z-axis moving module. The first rotary drive component is used to drive the Z-axis moving module to rotate. The cutting machine is rotatably mounted on the connecting arm; the connecting arm is provided with a second rotary drive component corresponding to the cutting machine, the second rotary drive component being used to drive the cutting machine to rotate.

[0014] By adopting the above technical solution, during cutting and trimming, the cutting angle can be adjusted by driving the cutting machine to rotate according to the end shape requirements of different types of leaf spring bodies, so as to adapt to the end shape of the target leaf spring body; during drilling, the drilling machine can be driven to rotate horizontally by driving the Z-axis moving module according to the arc-shaped curved surface structure of the target leaf spring body, so that the drilling angle of the drilling machine is perpendicular to the curved surface at the drilling point of the leaf spring, avoiding drilling deviation caused by the arc-shaped structure of the leaf spring, and improving the drilling accuracy; effectively improving the adaptability of the cutting and drilling assembly.

[0015] Preferably, the first clamping fixture includes a first clamping seat, a support portion protruding from the center of the first clamping seat, the support portion being used for the concave side of the leaf spring body to abut against, and a plurality of pneumatic clamping members being provided on the top of the support portion, the pneumatic clamping members being used to cooperate with the support portion to clamp the leaf spring body.

[0016] By adopting the above technical solution, when the leaf spring body is clamped by the first clamping fixture, the concave side of the leaf spring body is correspondingly abutted against the support part in the middle of the first clamping seat. After the support part supports and limits the bottom of the leaf spring body, several pneumatic clamping parts on the top of the support part press down on the top of the leaf spring body. The pneumatic clamping parts cooperate with the support part to clamp and limit the leaf spring body, so as to realize the clamping and fixing of the leaf spring body and limit the displacement of the leaf spring body during the cutting, trimming and drilling processes.

[0017] Preferably, both ends of the first clamping seat are provided with first pneumatic grippers, which are used to clamp the ends of the leaf spring body.

[0018] By adopting the above technical solution, the middle part of the leaf spring body is clamped and fixed by the support part and the pneumatic clamping part, while the end of the leaf spring body is clamped by the first pneumatic jaws located at both ends of the first clamping seat. This achieves multi-point clamping support for the leaf spring, which helps to further improve the stability and rigidity of the leaf spring body after clamping, and limits the deformation and shaking of the leaf spring end during cutting and drilling. It also avoids processing deviations such as irregular cutting and trimming and skewed drilling caused by end cantilever stress deformation.

[0019] Preferably, it also includes a dust removal mechanism, which includes a vacuum dust collector, the air inlet of which is connected to an air inlet pipe; Both the drilling machine and the chamfering machine are equipped with dust collection hoods, which surround the outer periphery of the drill rod of the corresponding drilling machine; the cutting machine includes a side cover and a cutting wheel, with the side cover fitted around the upper outer periphery of the cutting wheel; The dust collection hood and the top of the side cover are connected to the air inlet pipe via a telescopic flexible hose.

[0020] By adopting the above technical solution, when performing cutting, drilling and chamfering processes, the debris generated during processing can be promptly removed by a vacuum cleaner in conjunction with a dust collection hood and side cover, reducing dust overflow and scattering inside the equipment, and also reducing the impact of debris and dust on operators.

[0021] Preferably, the second clamping fixture includes a second clamping seat, the second clamping seat is provided with a plurality of second pneumatic grippers, the second pneumatic grippers are used to clamp the leaf spring body; The second clamping seat is supported at both ends by limiting rods, which are used for the end of the leaf spring body to abut against each other to limit the end of the leaf spring body.

[0022] By adopting the above technical solution, when the leaf spring body is clamped by the second clamping fixture, the leaf spring body is firmly clamped by several second pneumatic grippers of the second clamping seat. At the same time, the limiting rods at both ends of the second clamping seat abut and limit the ends of the leaf spring body, thereby achieving a stable clamping of the leaf spring body, preventing the leaf spring body from shifting or shaking during the chamfering process, and ensuring the accuracy of the chamfering process.

[0023] Preferably, the transfer mechanism includes a transfer robotic arm and a transfer drive component; The transfer robotic arm has a clamping part at its drive end for clamping the leaf spring body. The clamping part includes a clamping bracket. The clamping bracket has clamping cylinders on both sides. The clamping cylinders on both sides of the clamping bracket are arranged opposite each other. The piston rod end of each clamping cylinder is provided with a clamping block.

[0024] By adopting the above technical solution, when transferring the leaf spring body, the transfer drive unit drives the transfer robotic arm to move the clamping part to the corresponding clamping position of the leaf spring body on the first clamping fixture. Then, the clamping cylinders on both sides of the clamping bracket drive the clamping blocks to move towards each other until the two clamping blocks abut against the two sides of the leaf spring body, thereby clamping and fixing the leaf spring body. After clamping, the transfer drive unit, in conjunction with the transfer robotic arm, drives the clamping part and the leaf spring body to move as a whole, transferring the leaf spring body from the first clamping fixture to the preset position of the second clamping fixture. Finally, the piston rod of the clamping cylinder retracts, driving the two clamping blocks to move away from each other, thereby releasing the clamping limit on the leaf spring body. This realizes the automatic transfer of the leaf spring body between the cutting and drilling mechanism and the chamfering mechanism, effectively improving the connection efficiency between processes. Preferably, a support rod is vertically provided at the bottom of the two clamping blocks on the adjacent side, and the support rod is used for the concave side of the leaf spring body to abut.

[0025] By adopting the above technical solution, the two clamping cylinders drive the clamping blocks to abut against both sides of the leaf spring body, while the clamping blocks drive the corresponding support rods to abut against the bottom of the leaf spring body. The support rods support and limit the leaf spring body, effectively preventing the leaf spring body from falling and being damaged during the transfer process by detaching from the clamping blocks.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. After the leaf spring body to be processed is clamped onto the first clamping fixture, two cutting and drilling assemblies respectively trim and drill the two ends of the leaf spring body. After the trimming and drilling process is completed, the leaf spring body is transferred from the first clamping fixture to the second clamping fixture with a chamfering structure through the transfer mechanism, and the two edges at the top of the leaf spring are chamfered through the chamfering assembly, which effectively improves the processing efficiency of the leaf spring body.

[0027] 2. By setting first pneumatic grippers at both ends of the first clamping seat, the middle part of the leaf spring is clamped by the support plate and the pneumatic clamping component, while the two first pneumatic grippers clamp the two ends of the leaf spring body respectively. This helps to improve the overall rigidity of the leaf spring body and limit the deformation of the leaf spring end under force during the subsequent leaf spring drilling and trimming process.

[0028] 3. By vertically setting support rods at the bottom of the two clamping blocks in the clamping part, the support rods can support and limit the bottom of the leaf spring body while the two clamping blocks work together to clamp the leaf spring body, which helps to improve the clamping stability of the clamping part.

[0042] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0043] This application discloses an automatic post-processing equipment for composite leaf spring products, referring to... Figure 2 It includes a cutting and drilling mechanism 1, a chamfering mechanism 2, a transfer mechanism 3, and a dust removal mechanism 4.

[0044] Reference Figure 2 and Figure 3 The cutting and drilling mechanism 1 includes a cutting and drilling frame, on which a first clamping fixture 11 and a cutting and drilling assembly 12 are mounted. The first clamping fixture 11 is used to clamp the leaf spring body. The cutting and drilling assembly 12 is used to cut and trim the ends of the leaf spring and to drill holes.

[0045] Reference Figure 4 and Figure 5The first clamping fixture 11 includes a first clamping seat 112. A support portion 113 protrudes from the middle of the first clamping seat 112. The support portion 113 is used for the concave side of the leaf spring body to abut against it. A plurality of pneumatic clamping members 114 are provided on the top of the support portion 113. The pneumatic clamping members 114 are used to cooperate with the support portion 113 to clamp and limit the leaf spring body. Specifically, the pneumatic clamping member 114 includes a fixed rod 1141, a pressure arm 1142, and a drive cylinder 1143. The fixed rod 1141 is fixed to the outside of the support portion 113 by a support. The pressure arm 1142 is hinged to the top of the fixed rod 1141. The two ends of the pressure arm 1142 are a pressing end and a driving end, respectively. The pressing end of the pressure arm 1142 extends above the support portion 113. The top of the cylinder body of the drive cylinder 1143 is hinged to the bottom end of the fixed rod 1141, and the top of the piston rod of the drive cylinder 1143 is hinged to the driving end of the pressure arm 1142.

[0046] When the leaf spring body is clamped by the first clamping fixture 11, the pressure arm 1142 is driven upward by the drive cylinder 1143 of the pneumatic clamping member 114 to move away from the support part 113, and then the concave side of the leaf spring body is placed on the support part 113. Then the pressure arm 1142 is driven downward by the drive cylinder 1143 of the pneumatic clamping member 114 to cooperate with the support part 113 to clamp the leaf spring body.

[0047] Reference Figure 3 and Figure 7 The cutting and drilling assembly 12 includes two drilling robotic arms 121, located on either side of the first clamping fixture 11. Each drilling robotic arm 121 includes an X-axis moving module 1211, a Y-axis moving module 1212, a connecting arm 1213, and a Z-axis moving module 1214. All three modules—X-axis 1211, Y-axis 1212, and Z-axis 1214—are electrically driven linear modules. Specifically, the Y-axis moving module 1212 is mounted on the moving end of the X-axis moving module 1211, and the connecting arm 1213 is vertically mounted on the moving end of the Y-axis moving module 1212. The X-axis and Y-axis moving modules 1212 drive the connecting arm 1213 to move within a two-dimensional plane. The Z-axis moving module 1214 is rotatably connected to the top end of the connecting arm 1213. The top end of the connecting arm 1213 is also provided with a first rotary drive 124 for driving the Z-axis moving module 1214 to rotate around its own rotating end. In this embodiment, the first rotary drive 124 is a worm gear reducer motor.

[0048] Reference Figure 6 and Figure 7The cutting machine 123 is rotatably connected to the connecting arm 1213, and the cutting wheel of the cutting machine 123 is positioned facing the first clamping fixture 11. The axial direction of the rotating end of the cutting machine 123 is parallel to the axial direction of the rotating end of the Z-axis moving module 1214. The top of the connecting arm 1213 is also provided with a second rotary drive 125 for driving the cutting machine 123 to rotate around its own rotating end. In this embodiment, the second rotary drive 125 is a worm gear reducer motor. When cutting and trimming the end of the leaf spring body, the X-axis moving module 1211 and the Y-axis moving module 1212 move the cutting machine 123 to the cutting position at the end of the leaf spring and cooperate with the cutting machine 123 to complete the burr cutting at the end of the leaf spring.

[0049] By rotatably connecting the cutting machine 123 to the connecting arm 1213 and driving the cutting machine 123 to rotate via the second rotary drive 125, it is convenient to adjust the cutting angle of the cutting wheel by driving the cutting machine 123 to rotate according to the end shape requirements of different types of leaf spring bodies, so as to adapt to the end shape of the target leaf spring body, which helps to improve the applicability of the cutting machine 123.

[0050] Reference Figure 3 and Figure 6 The drilling machine 122 is mounted on the moving end of the Z-axis moving module 1214. When drilling the leaf spring body, the X-axis moving module 1211 and the Y-axis moving module 1212 move the drilling machine 122 to the corresponding drilling position on the leaf spring body, and then the Z-axis moving module 1214 drives the drilling machine 122 to feed to perform drilling operations on the end of the leaf spring body.

[0051] By horizontally rotating the Z-axis moving module 1214 to the top of the connecting arm 1213 and driving the Z-axis moving module 1214 to rotate via the first rotary drive 124, during drilling, the Z-axis moving module 1214 can be driven by the first rotary drive 124 to drive the drilling machine 122 to rotate horizontally according to the arc-shaped curved surface structure of the target leaf spring body. This ensures that the drilling angle of the drilling machine 122 is perpendicular to the curved surface at the leaf spring drilling point, avoiding drilling deviation and improving drilling accuracy.

[0052] Reference Figure 4 and Figure 5 Both ends of the first clamping seat 112 are provided with first pneumatic grippers 115. The first pneumatic grippers 115 are used to clamp the end of the leaf spring body to improve the overall rigidity of the leaf spring body and limit the deformation and damage of the end of the leaf spring body when the subsequent cutting and drilling assembly 12 drills and cuts the end of the leaf spring body.

[0053] Reference Figure 3 and Figure 4The cutting and drilling frame is also equipped with a first clamping drive unit 111 corresponding to the first clamping fixture 11. The first clamping drive unit 111 is used to drive the first clamping fixture 11 to move towards or away from the cutting and drilling assembly 12. Specifically, the first clamping drive unit 111 adopts an electric linear module, and the first clamping fixture 11 is installed on the moving end of the corresponding electric linear module. When clamping or disassembling the leaf spring body, the first clamping fixture 11 is driven away from the cutting and drilling assembly 12 by the first clamping drive unit 111 to avoid interference and collision, thereby reducing the difficulty of clamping the leaf spring body.

[0054] Reference Figure 8 and Figure 9 Specifically, the chamfering mechanism 2 includes a chamfering frame, on which a second clamping fixture 21 and a chamfering assembly 22 are mounted. The second clamping fixture 21 is used to clamp the leaf spring body. The second clamping fixture 21 includes a second clamping seat 210, with support blocks 211 at both ends of the second clamping seat 210. The support blocks 211 are used for the concave side of the leaf spring body to abut against, thereby supporting the leaf spring body. Second pneumatic grippers 212 are provided on opposite sides of the support blocks 211, and the second pneumatic grippers 212 are used to clamp the leaf spring body. When the concave side of the leaf spring body abuts against the two support blocks 211, the leaf spring body is located between the two clamping blocks 323 of the second pneumatic grippers 212, and the convex side of the leaf spring body is set higher than the clamping blocks 323 of the second pneumatic grippers 212.

[0055] Reference Figure 8 and Figure 9 The second clamping seat 210 is supported at both ends by limiting rods 213. The limiting rods 213 are used for the end of the leaf spring body to abut against each other to limit the end of the leaf spring body.

[0056] Reference Figure 8 and Figure 9 The chamfering assembly 22 is positioned near the second clamping fixture 21. Specifically, the chamfering assembly 22 includes a chamfering robotic arm 220, a chamfering drill 221, a detection component, and a control system. The chamfering robotic arm 220 is a six-axis robotic arm, and the chamfering drill 221 is fixed to the drive end of the chamfering robotic arm 220 via a connecting seat. The detection component includes a vision sensor 222 mounted on the connecting seat.

[0057] Reference Figure 8 and Figure 9The control system uses an existing PLC controller. The chamfering robot arm 220, vision sensor 222, and chamfering drill 221 are all electrically connected to the control system. When the chamfering assembly 22 performs chamfering on the leaf spring body clamped by the second clamping fixture 21, the vision sensor 222 acquires the top edge contour image of the target leaf spring body and feeds it back to the control system. The control system controls the chamfering robot arm 220 to work with the chamfering drill 221 to perform chamfering on both sides of the top of the leaf spring based on the leaf spring edge contour image data fed back by the vision sensor 222.

[0058] Reference Figure 8 and Figure 9 The chamfering frame is also equipped with a second clamping drive 214, which drives the second clamping fixture 21 to move towards or away from the chamfering assembly 22. Specifically, the second clamping drive 214 is an electric linear module, and the second clamping fixture 21 is mounted on the moving end of the corresponding electric module. When clamping or disassembling the leaf spring body, the second clamping fixture 21 is driven away from the chamfering assembly 22 by the second clamping drive 214 to avoid interference and collision, thereby reducing the difficulty of clamping the leaf spring body.

[0059] Reference Figure 2 and Figure 10 The transfer mechanism 3 is located near the cutting and drilling mechanism 1 and the chamfering mechanism 2. The transfer mechanism 3 is used to transfer the leaf spring body located in the first clamping fixture 11 to the second clamping fixture 21. Specifically, the transfer mechanism 3 includes a transfer robotic arm 31, a clamping part 32, and a transfer drive member 33.

[0060] Reference Figure 10 and Figure 11 The transfer robotic arm 31 is a six-axis robotic arm. The clamping part 32 is used to clamp the leaf spring body. The clamping part 32 includes a clamping bracket 321. The clamping bracket 321 is provided with clamping cylinders 322 on both sides of the clamping bracket 321. The clamping cylinders 322 on both sides of the clamping bracket 321 are arranged opposite to each other. The piston rod end of the clamping cylinder 322 is provided with a clamping block 323. The clamping cylinders 322 are used to drive the corresponding clamping blocks 323 to move relative to each other to complete the clamping and fixing of the leaf spring body.

[0061] Reference Figure 10 and Figure 11 Each of the two clamping blocks 323 has a vertically arranged support rod 324 at its bottom edge on the side closest to each other. Specifically, there are two support rods 324, located at opposite ends of the clamping blocks 323. The support rods 324 are used to abut against the concave side of the leaf spring body. When the two clamping blocks 323 move relative to each other to clamp the leaf spring body, the support rods 324 located at the bottom of the clamping blocks 323 abut against the bottom of the leaf spring body, preventing the leaf spring body from falling out of the clamping limit of the clamping blocks 323, which helps to improve the clamping stability of the clamping part 32 on the leaf spring body.

[0062] Reference Figure 10 and Figure 11 The transfer drive unit 33 includes a transfer linear module, and the transfer robotic arm 31 is mounted on the moving end of the transfer linear module.

[0063] After the subsequent cutting and drilling mechanism 1 completes the trimming and drilling process on the end of the leaf spring body, the transfer drive 33, in conjunction with the transfer robotic arm 31, drives the clamping part 32 and the leaf spring body to move as a whole, transferring the leaf spring body from the first clamping fixture 11 to the preset position of the second clamping fixture 21. Finally, the piston rod of the clamping cylinder 322 retracts, driving the two clamping blocks 323 on both sides to move in opposite directions, thereby releasing the clamping limit on the leaf spring body.

[0064] Reference Figure 3 , Figure 7 , Figure 8 and Figure 12 The dust removal mechanism 4 includes a vacuum dust collector 41, and the air inlet end of the vacuum dust collector 41 is connected to an air inlet pipe 42. Both the drilling machine 122 and the chamfering drilling machine 221 have dust collection covers 43 on the outer periphery of the top of the drill rod. The length of the dust collection cover 43 is shorter than that of the drill rod. The outer side of the dust collection cover 43 is connected to the dust discharge pipe 432 through a connecting pipe 431. The upper outer periphery of the cutting wheel of the cutting machine 123 is fitted with a side cover 1231. The dust discharge pipe 432 and the side cover 1231 are connected to the air inlet pipe 42 through a telescopic hose.

[0065] When drilling and chamfering are performed by drilling machine 122 and chamfering machine 221 respectively, and cutting and trimming are performed by cutting machine 123, the generated debris and dust can be promptly removed by vacuum dust collector 41 in conjunction with telescopic hose. This helps to reduce dust overflow and scatter inside the equipment, and at the same time reduces the impact of debris and dust on operators.

[0066] Reference Figure 3 and Figure 7 The bottom of the X-axis moving module 1211 of the cutting and drilling robot arm 121 is also equipped with a collection component, which includes a chain plate chip conveyor 120 and a collection trolley 1201. The chain plate chip conveyor 120 is located below both the cutting machine 123 and the drilling machine 122 and is used to collect the chips generated during the processing of the cutting machine 123 and the drilling machine 122.

[0067] The implementation principle of this application embodiment is as follows: Leaf spring body loading: The leaf spring body to be processed is placed on the first clamping fixture 11, which clamps and fixes the leaf spring body; and the first clamping drive 111 drives the first clamping fixture 11 to move the leaf spring body to the cutting and drilling assembly 12. Cutting and drilling: The two ends of the leaf spring are cut, trimmed and drilled by the cutting and drilling assembly 12.

[0068] Leaf spring body transfer: The first clamping drive 111 drives the first clamping fixture 11 to move the leaf spring body away from the cutting and drilling assembly 12. Then the first clamping fixture 11 releases the clamping fixation of the leaf spring body. The transfer drive 33, in cooperation with the transfer robot arm 31 and the clamping part 32, transfers the leaf spring body from the first clamping fixture 11 to the second clamping fixture 21 of the cutting machine 123. The second clamping fixture 21 clamps and fixes the leaf spring body. The second clamping drive 214 drives the second clamping fixture 21 to move the leaf spring body to the chamfering assembly 22.

[0069] Chamfering: The top edge of the leaf spring body is chamfered by using a chamfering robotic arm 220 in conjunction with a chamfering drill 221.

[0070] This application enables automatic end cutting and trimming, drilling, and chamfering of the top edges of the leaf spring body, effectively improving the post-processing efficiency of the leaf spring body.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
