Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing equipment technology, and in particular to a high-frequency heating and riveting equipment for automotive latches. Background Technology

[0002] In the automotive manufacturing industry, the riveting of latch components is a key process to ensure the stability and safety of the vehicle body structure. The quality of the riveting directly affects the reliability and service life of the latches. In traditional processing methods, latches are usually riveted using cold riveting or ordinary heating followed by riveting. At the same time, traditional riveting equipment often adopts a step-by-step processing mode, which requires manual or mechanical devices to transfer the workpiece between the heating station and the riveting station. Traditional equipment and processing methods have significant limitations.

[0003] 1. Material Deformation and Damage: During cold riveting, high-strength metal materials are prone to cracking due to local stress concentration. Ordinary heating methods (such as flame or resistance heating) have inaccurate temperature control, which can easily lead to uneven heating of the workpiece and affect the structural strength after riveting.

[0004] 2. Low efficiency: Existing equipment mostly requires manual loading and unloading, and the heating and riveting processes are separated, resulting in long processing cycles and low automation, making it difficult to meet the needs of large-scale production;

[0005] 3. Low equipment integration: The heating device (such as flame jet or resistance heating) is set up separately from the riveting mechanism, which occupies a large space, consumes a lot of energy, and makes it difficult to control the uniformity of heating;

[0006] Based on this, the applicant proposed a high-frequency heating and riveting device for automotive latches to solve the above technical problems. Utility Model Content

[0007] This utility model addresses the shortcomings of existing technologies by providing a high-frequency heating and riveting device for automotive lock buckles, thereby solving the aforementioned technical problems.

[0008] This utility model is solved by the following technical solution:

[0009] A high-frequency heating and riveting device for automotive latches includes a clamping table, on which a workpiece is fixed. The clamping table moves to a heating mechanism, which heats the workpiece at high frequency. The clamping table then moves to a riveting mechanism, which performs riveting processing on the workpiece.

[0010] Preferably, it further includes a main cylinder fixedly mounted on the processing table, the clamping table being slidably mounted on the processing table, and the clamping table being fixedly connected to the end of the telescopic rod of the main cylinder.

[0011] Preferably, the processing table is also provided with a gripper mechanism and a positioning buffer mechanism. When the gripper table moves to the furthest point from the main cylinder, the gripper mechanism and the gripper table cooperate to load the workpiece. When the gripper table moves to the positioning buffer mechanism, the heating mechanism is above the workpiece. When the gripper table moves to the closest point to the main cylinder, the riveting mechanism is above the gripper table and cooperates with the gripper table to achieve riveting.

[0012] Preferably, the clamping table includes a slide table, a slider is provided on the lower side of the slide table, a guide rail is provided on the processing table, the slider is slidably disposed on the guide rail, a guide groove is provided on the upper side of the slide table, two clamping blocks are slidably disposed in the guide groove, the two clamping blocks are connected by a spring, and a connecting block is also provided on the outside of the clamping block to cooperate with the gripper mechanism.

[0013] Preferably, the gripper mechanism includes a bracket, on which an auxiliary cylinder is fixedly mounted. An electric gripper is fixedly mounted on the telescopic rod of the auxiliary cylinder. The electric gripper includes two slidingly opening and closing claw heads. When the two claw heads slide closed, they form a T-shaped limiting groove. A T-shaped limiting block is provided at the end of the connecting block away from the gripper block. The T-shaped limiting groove is adapted to the T-shaped limiting block.

[0014] Preferably, the positioning and buffering mechanism includes an L-shaped fixing plate, on which a buffer cylinder is fixedly mounted. A buffer block is mounted on the telescopic rod of the buffer cylinder. When the clamping platform moves to contact the buffer block, the heating mechanism operates.

[0015] Preferably, the heating mechanism includes a high-frequency machine with a heating head connected to it. When the clamping table moves to contact the buffer block, the workpiece is located below the heating head.

[0016] Preferably, the riveting mechanism includes a mounting frame fixedly installed on the processing table, a pressure cylinder fixedly installed on the upper side of the mounting frame, a connecting rod installed on the lower side of the pressure cylinder, the connecting rod passing through the mounting frame and connected to a stripper plate, and a punch installed inside the stripper plate.

[0017] Preferably, a guide post is also fixedly installed on the connecting rod by a clamp, and the guide post is slidably connected to the mounting bracket.

[0018] Preferably, a positioning plate is also fixedly provided on the connecting rod, with positioning blocks extending from both sides of the positioning plate, and a positioning groove provided on the side of the clamping block, wherein the positioning block is adapted to the positioning groove.

[0019] Preferably, a pressure block is also fixedly provided on the processing table, and a limiting groove is provided on the pressure block, which is adapted to the clamping block.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. Reduce material damage and improve riveting quality: High-frequency induction heating technology is used to quickly and uniformly heat the workpiece through a high-frequency machine and heating head, avoiding the temperature fluctuations and local overheating problems of traditional heating methods. This effectively reduces riveting stress and prevents material cracks. At the same time, the precise cooperation between the positioning buffer mechanism and the clamping table, combined with the adaptive design of the positioning block and positioning groove, ensures the stability of the workpiece position during riveting and eliminates riveting defects caused by displacement.

[0022] 2. High-efficiency integrated production: The sliding design of the clamping table driven by the main cylinder enables seamless connection of heating and riveting processes. Combined with the quick locking of the gripper mechanism and T-shaped limit block, manual intervention is reduced, the processing cycle is shortened, and production efficiency is significantly improved to meet the needs of large-scale production.

[0023] 3. Optimization of equipment compactness and energy efficiency: The high-frequency heating mechanism, riveting mechanism, clamping table and other modules are integrated into the same processing table. The sliding layout of guide rails and sliders greatly reduces the equipment footprint. Compared with traditional resistance or flame heating, high-frequency heating technology reduces energy consumption and the heating uniformity is controllable, further reducing production costs.

[0024] 4. Full-process automation and high-precision control: Through the coordinated action of the main cylinder and the buffer cylinder, the precise positioning and buffering of the clamping table movement are achieved; the riveting mechanism driven by the booster cylinder, combined with the punch and stripper plate, ensures precise control of the riveting pressure and depth, guarantees product consistency, and effectively solves the quality fluctuation problem caused by manual operation in traditional processes.

[0038] The technical solutions of various embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1:

[0039] like Figures 1 to 11As shown, the high-frequency heating and riveting equipment for automotive locks of this utility model includes a clamping table 1, on which the workpiece is fixed. The clamping table 1 moves to a heating mechanism 2. After the heating mechanism 2 heats the workpiece at high frequency, the clamping table 1 moves to a riveting mechanism 3, where the riveting mechanism 3 performs riveting processing on the workpiece.

[0040] It also includes a main cylinder 5 fixedly mounted on the processing table 4, and the clamping table 1 is slidably mounted on the processing table 4. The clamping table 1 is fixedly connected to the end of the telescopic rod of the main cylinder 5.

[0041] The processing table 4 is also equipped with a gripper mechanism 6 and a positioning buffer mechanism 7. When the clamping table 1 moves to the furthest point from the main cylinder 5, this is the loading station. The gripper mechanism 6 is connected to the clamping table 1 to load the material. When the clamping table 1 moves to the positioning buffer mechanism 7, this is the high-frequency heating station. The heating mechanism 2 is located above the workpiece. When the clamping table 1 moves to the closest point to the main cylinder 5, this is the riveting station. The riveting mechanism 3 is located above the clamping table 1 and cooperates with the clamping table 1 to achieve riveting.

[0042] The clamping table 1 includes a slide table 11, with a slider 12 disposed on the lower side of the slide table 11. A guide rail 41 is disposed on the processing table 4, and the slider 12 is slidably disposed on the guide rail 41. A guide groove 13 is disposed on the upper side of the slide table 11, and two clamping blocks 14 are slidably disposed within the guide groove 13. The two clamping blocks 14 are connected by a spring 15. When the two clamping blocks 14 are closed, the spring 15 is in a stretched state, and the elastic force of the spring 15 ensures that the two clamping blocks 14 clamp the workpiece without external pressure. It has a certain clamping force to ensure the stability of the workpiece during the movement of the clamping table 1 and the processing of the device. In order to ensure the smooth sliding of the clamping block 14 and the stability and consistency of the workpiece clamping, a guide rod can also be set between the two clamping blocks 14. A connecting block 16 is also set on the outside of the clamping block 14 to cooperate with the gripper mechanism 6. In order to ensure the stability of the movement and processing process, two guide rails 41 are arranged in parallel. There are a total of four sliders 12 on the lower side of the slide table 11, which are arranged symmetrically, with two sliders arranged on each guide rail 41.

[0043] The gripper mechanism 6 includes a bracket 61, on which a secondary cylinder 62 is fixedly mounted. An electric gripper 63 is fixedly mounted on the telescopic rod of the secondary cylinder 62. The electric gripper 63 includes two slidingly opening and closing claw heads 631. When the two claw heads 631 slide closed, they form a T-shaped limiting groove 632. A T-shaped limiting block 161 is provided at the end of the connecting block 16 away from the gripping block 14. The T-shaped limiting groove 632 is adapted to the T-shaped limiting block 161. The gripper mechanism 6 is symmetrically arranged and corresponds to the two connecting blocks 16 respectively.

[0044] The positioning and buffering mechanism 7 includes an L-shaped fixed plate 71, on which a buffer cylinder 72 is fixedly mounted. A stop is provided on the telescopic rod of the buffer cylinder 72, and a buffer block 73 is provided on the stop. When the clamping table 1 moves to contact the buffer block 73, the heating mechanism 2 operates. The positioning and buffering mechanism 7 is equivalent to a positioner and a trigger. When the clamping table 1 moves to this position, the heating mechanism 2 is triggered to operate.

[0045] The heating mechanism 2 includes a high-frequency machine 21, on which a heating head 22 is connected. When the clamping table 1 moves to contact the buffer block 73, the workpiece is located below the heating head 22.

[0046] The riveting mechanism 3 includes a mounting frame 31 fixedly mounted on the processing table 4. A booster cylinder 32 is fixedly mounted on the upper side of the mounting frame 31, and a connecting rod 33 is mounted on the lower side of the booster cylinder 32. The connecting rod 33 passes through the mounting frame 31 and is connected to a stripper plate 34. A punch 35 is disposed inside the stripper plate 34. A guide post 37 is also fixedly mounted on the connecting rod 33 by a clamp 36. The guide post 37 is slidably connected to the mounting frame 31. A further fixed component is also mounted on the connecting rod 33. A positioning plate 38 is provided, with positioning blocks 381 extending from both sides of the positioning plate 38. A positioning groove 141 is provided on the side of the clamping block 14. The positioning blocks 381 are adapted to the positioning groove 141, thereby limiting the clamping block 14 and ensuring the stability of the workpiece during riveting. A pressure block 8 is also fixedly provided on the processing table 4. The pressure block 8 is provided with a limiting groove 81, which is adapted to the clamping block 14 for further limiting, thereby ensuring the consistency of processing.

[0047] Initially, the clamping table 1 is in the loading position. Simultaneously, the two jaws 631 of the electric gripper 63 slide closed and engage with the T-shaped limiting block 161 at the end of the connecting block 16. During loading, two auxiliary cylinders 62 control the two electric grippers 63 to move to both sides, thereby controlling the two clamping blocks 14 to slide open. After the workpiece is placed, the auxiliary cylinders 62 control the electric grippers 63 to reset, and the clamping blocks 14 clamp the workpiece, completing the loading. The electric grippers 63 control the two jaws to slide open, releasing the engagement with the T-shaped limiting block 161. The auxiliary cylinders 62 control the electric grippers 63 to move to both sides, preventing motion interference during subsequent movement of the clamping table 1. The main cylinder 5 operates, its telescopic rod retracts, driving the clamping table 1 to slide towards the high-frequency heating position. During this process, the buffer cylinder 72 operates, controlling the buffer block 73 to extend to the front of the clamping table 1. When the clamping table 1 contacts the buffer block 73, the high-frequency machine 21 operates. The heating head 22 performs high-frequency heating on the workpiece to be processed. The specific heating parameters are adjusted and determined by those skilled in the art according to the actual situation. After the workpiece is heated, the buffer cylinder 72 operates to control the buffer block 73 to reset, releasing the interference to the movement of the clamping table 1. The main cylinder 5 continues to operate, driving the clamping table 1 to move towards the riveting station. When it reaches the riveting station, the clamping block 14 cooperates with the limiting groove 81 on the pressure block 8 to limit the movement. Then the booster cylinder 32 starts, and the punch 35 completes the riveting of the workpiece. Then the stripper plate 34 completes the separation of the workpiece from the punch 35. At this point, the workpiece riveting is completed. The main cylinder 5 operates, and its telescopic rod extends, driving the clamping table 1 to reset to the loading station. The two auxiliary cylinders 62 control the two electric grippers 63 to move to both sides, thereby controlling the two clamping blocks 14 to slide open. After the processed workpiece is removed, the workpiece to be processed is loaded again. The above operations are repeated to achieve industrialized and automated production.
