Description
Technical Field
[0001] This utility model relates to the field of punching equipment technology, specifically to a shim punching equipment with automatic positioning compensation. Background Technology
[0002] In gasket manufacturing, the circular piece is a single unit. A punching device is used to drill a hole in the center of the circular piece, shaping it into a ring-shaped gasket. The punching process requires precise positioning of the circular piece to ensure accuracy. Positioning compensation refers to a technology that uses sensors, control systems, and algorithms to detect and correct positional deviations in real time during robot assembly, thereby improving assembly accuracy and efficiency. Its core lies in dynamically adjusting the position of the robot's end effector to ensure precise alignment. In punching equipment, automatic positioning compensation utilizes sensors to adjust the position of the punching table, ensuring precise alignment between the punching table and the punching head, thus making gasket manufacturing more accurate.
[0003] However, existing shim punching equipment with automatic positioning compensation uses a jig to position the round piece during punching. Then, a compensation mechanism adjusts the entire jig table, i.e., the punching table, to ensure precise alignment with the punching head. But during punching, the round piece is not fixed inside the jig table's placement slot; it is only limited by the side wall of the slot. When the punching head presses down, the round piece may shift or the center of the round piece may be concave and the edges may warp. This not only affects the accuracy of shim punching but also the stability of the shim punching process, thus greatly affecting the quality of shim punching.
[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a gasket punching device with automatic positioning compensation. Utility Model Content
[0005] The purpose of this invention is to provide a gasket punching device with automatic positioning compensation to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a gasket punching device with automatic positioning compensation, comprising a worktable, a punching platform slidably fitted on the upper surface of the worktable, forming cavities evenly distributed on the upper surface of the punching platform, a cylinder above the worktable, a push plate fixedly connected to the bottom end of the cylinder, punching heads evenly distributed and fixedly connected to the lower surface of the push plate, a ring plate fixedly installed on the surface of the punching head, a spring fixedly connected to the lower surface of the ring plate, a clamping ring fixedly installed at the bottom end of the spring, and the clamping ring located below the punching head.
[0007] Preferably, the area of the push plate matches the size of the punching platform, the number of punch heads is the same as the number of forming cavities, and the installation position of the punch heads on the lower surface of the push plate is the same as the position of the forming cavities opened on the surface of the punching platform.
[0008] Preferably, the forming cavity consists of a circular groove and a through cavity in the middle of the circular groove, wherein the diameter of the through cavity is smaller than the diameter of the circular groove, the diameter of the ring plate is larger than the diameter of the circular groove, the diameter of the clamping ring matches the diameter of the circular groove, and the diameter of the punch head matches the diameter of the through cavity in the middle of the forming cavity.
[0009] Preferably, a bracket is fixedly installed on the right side of the upper surface of the workbench, and the cylinder is fixedly connected to the bracket through it. A distance sensor is fixedly connected to the lower inner wall of the bracket, and the distance sensor is horizontally aligned with the punching table.
[0010] Preferably, a cavity is provided on the left side of the surface of the punching platform, the upper side of the inner surface of the cavity is connected to the through cavity of the forming cavity, and the bottom of the inner surface of the cavity is set as an inclined surface. A collection box is fixedly connected to the lower left side of the surface of the punching platform.
[0011] Preferably, a groove is provided in the middle of the upper surface of the workbench, and a slider is slidably disposed on the inner surface of the groove, with the upper end of the slider being fixedly connected to the punching table.
[0012] Preferably, side plates are fixedly connected to both the left and right sides of the front surface of the worktable, and a drive motor is fixedly connected to the right side of the surface of the right side plate. The same lead screw is rotatably connected to the opposite side of the surface of the side plate, and the right end of the lead screw passes through the side plate and is connected to the drive motor.
[0013] Preferably, an adjusting plate is fixedly connected to the front side of the punching table, and the lower end of the adjusting plate is threadedly sleeved onto the surface of the lead screw.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model, through the arrangement of a punching table, forming cavity, cylinder, push plate, punching head, ring plate, spring, and clamping ring, allows a round workpiece to be placed in the forming cavity. The punching table and push plate are vertically aligned. The cylinder can push the push plate downward, thereby inserting the punching head into the forming cavity. The round workpiece is penetrated through the cavity, forming a ring in the circular groove. This punching process creates a gasket. During the punching process, the clamping ring first extends into the circular groove of the forming cavity and fits against the round workpiece. As the push plate drives the punching head deeper, the ring plate also continues to move downward. Since the clamping ring is already fitted against the round workpiece and cannot be pressed down further, the downward movement of the ring plate compresses the spring, increasing the spring's elastic force. The spring then pushes the clamping ring to tightly and firmly squeeze the round workpiece, thus fixing the round workpiece stably in the forming cavity. In other words, during the punching process, it can effectively prevent the round workpiece from shifting or undergoing other changes, making the punching process smoother and improving the quality of the gasket punching process.
[0016] 2. With the design of the cavity and the collection box, the remaining material of the round piece after the punch head passes through the middle of the round piece will fall directly into the cavity through the through cavity of the forming cavity. The remaining material will slide to the left using the inclined surface of the cavity and enter the collection box for storage, so as to automatically discharge the remaining material in a timely manner and collect the remaining material reasonably for subsequent recycling.
[0017] 3. This utility model, through the arrangement of a sliding groove, slider, side plate, lead screw, drive motor, adjusting plate, and distance sensor, utilizes the distance sensor to monitor the distance between the punching table and itself, while the position of the push plate is fixed. By continuously monitoring the distance from the distance sensor, it can determine whether the moving position of the punching table corresponds vertically to the push plate. If there is a deviation from the set distance, the PLC controller starts the drive motor to rotate the lead screw. The adjusting plate and punching table, limited by the sliding groove and slider, will not rotate with the lead screw but will only move under the thrust of the screw thread. This allows the entire punching table to adjust its position until it matches the distance set by the distance sensor. At this point, the drive motor stops, and the punching table is vertically aligned with the push plate, enabling precise punching. This allows the punching equipment to automatically adjust the position of the punching table and accurately locate the adjusted position, significantly improving the overall accuracy of the punching process.

[0022] 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.
[0023] like Figures 1-3 As shown, a gasket punching device with automatic positioning compensation includes a worktable 1. A punching table 2 is slidably attached to the upper surface of the worktable 1. Forming cavities 3 are evenly distributed on the upper surface of the punching table 2. A cylinder 4 is arranged above the worktable 1. A push plate 5 is fixedly connected to the bottom end of the cylinder 4. A punching head 6 is evenly distributed and fixedly connected to the lower surface of the push plate 5. A ring plate 7 is fixedly installed on the surface of the punching head 6. A spring 8 is fixedly connected to the lower surface of the ring plate 7. A clamping ring 9 is fixedly installed at the bottom end of the spring 8. The clamping ring 9 is located below the punching head 6.
[0024] The area of the push plate 5 matches that of the punching table 2, the number of punch heads 6 is the same as the number of forming cavities 3, and the installation position of the punch heads 6 on the lower surface of the push plate 5 is the same as the position of the forming cavity 3 opened on the surface of the punching table 2.
[0025] The forming cavity 3 consists of a circular groove and a through cavity in the middle of the circular groove. The diameter of the through cavity is smaller than the diameter of the circular groove, and the diameter of the ring plate 7 is larger than the diameter of the circular groove. The diameter of the clamping ring 9 matches the diameter of the circular groove, and the diameter of the punch head 6 matches the diameter of the through cavity in the middle of the forming cavity 3.
[0026] By adopting the above technical solution, the cylinder 4 can push the push plate 5 to move downward, thereby inserting the punch head 6 into the forming cavity 3, and passing through the middle position of the disc through the through cavity of the forming cavity, so that the disc forms a ring in the circular groove, and then punches the disc to form a gasket.
[0027] When the punching is pressed down, the clamping ring 9 first extends into the circular groove of the forming cavity 3, fits against the disc, and positions the disc.
[0028] As the push plate 5 drives the punch head 6 to continue to penetrate deeper, the ring plate 7 will also continue to move downwards. The clamping ring 9 is already in contact with the disc and cannot be pressed down. At this time, the downward movement of the ring plate 7 will compress the spring 8, thereby increasing the elastic force of the spring 8. The spring 8 can then push the clamping ring 9 to tightly and firmly squeeze the disc, thereby making the disc stably located in the forming cavity 3 for fixation.
[0029] Furthermore, a bracket 10 is fixedly installed on the right side of the upper surface of the workbench 1, and the cylinder 4 is fixedly connected to the bracket 10 through it. A distance sensor 19 is fixedly connected to the lower inner wall of the bracket 10, and the distance sensor 19 is horizontally corresponding to the punching table 2.
[0030] By adopting the above technical solution, at the vertically corresponding positions of the punching platform 2 and the push plate 5, the distance sensor 19 is manually calibrated to a fixed value at this time. The distance sensor 19 is used to monitor the distance between the punching platform 2 and itself, while the position of the push plate 5 is fixed. Thus, the distance length continuously fed back by the distance sensor 19 can be used to determine whether the moving position of the punching platform 2 is vertically corresponding to that of the push plate 5.
[0031] Furthermore, a cavity 11 is provided on the left side of the surface of the punching platform 2. The upper side of the inner surface of the cavity 11 is connected to the through cavity of the forming cavity 3, and the bottom of the inner surface of the cavity 11 is set as an inclined surface. A collection box 12 is fixedly connected to the lower left side of the surface of the punching platform 2.
[0032] By adopting the above technical solution, after the punch head 6 passes through the middle of the disc, the remaining disc material will fall directly into the cavity 11 through the cavity of the forming cavity 3. The remaining material will slide to the left using the inclined surface of the cavity 11 and enter the collection box 12 for storage, thereby enabling timely and automatic discharge of the remaining material and reasonable collection of the remaining material.
[0033] Furthermore, a groove 13 is provided in the middle of the upper surface of the workbench 1, and a slider 14 is slidably arranged on the inner surface of the groove 13. The upper end of the slider 14 is fixedly connected to the punching table 2.
[0034] By adopting the above technical solution, the slider 14 is limited by the slide groove 13, thereby limiting the punching table 2, so that the punching table 2 can only slide left and right and cannot perform other operations.
[0035] Furthermore, side plates 15 are fixedly connected to both the left and right sides of the front surface of the workbench 1, and a drive motor 17 is fixedly connected to the right side of the surface of the right side plate 15. The same lead screw 16 is rotatably connected to the opposite side of the surface of the side plate 15, and the right end of the lead screw 16 passes through the side plate 15 and is connected to the drive motor 17.
[0036] An adjusting plate 18 is fixedly connected to the front side of the punching table 2, and the lower end of the adjusting plate 18 is threadedly connected to the surface of the lead screw 16.
[0037] By adopting the above technical solution, if there is a deviation between the distance between the distance sensor 19 and the punching table 2 and the set distance, the drive motor 17 is started by the PLC controller to rotate the lead screw 16. Under the limit of the slide groove 13 and the slider 14, the adjusting plate 18 and the punching table 2 will not rotate with the lead screw 16, but will only be moved by the thread thrust, thereby driving the entire punching table 2 to adjust its position until the position of the punching table 2 is consistent with the judgment distance set by the distance sensor 19. Then the drive motor 17 stops working, and the punching table 2 can be vertically aligned with the push plate 5.
[0038] Working Principle: When using this shim punching machine with automatic positioning compensation, firstly, the round workpiece is placed in the forming cavity 3. Then, the distance sensor 19 is activated to make a judgment. The distance sensor 19 monitors the distance between the punching table 2 and itself, while the position of the push plate 5 is fixed. Thus, the distance length continuously fed back by the distance sensor 19 can be used to determine whether the moving position of the punching table 2 corresponds vertically to the push plate 5. If there is a deviation between the distance and the set distance, the drive motor 17 is activated by the PLC controller to rotate the lead screw 16. Under the limit of the slide groove 13 and the slider 14, the adjusting plate 18 and the punching table 2 will not follow the rotation of the lead screw 16, but will only be moved by the thread thrust, thus driving the entire punching table 2 to adjust its position until the position of the punching table 2 is consistent with the judgment distance set by the distance sensor 19. Then, the drive motor 17 stops working. At this time, the punching table 2 can be vertically aligned with the push plate 5. Then, the cylinder 4 can be activated to push the push plate 5 downward. During punching, the clamping ring 9 first extends into the circular groove of the forming cavity 3, fitting against the disc. As the push plate 5 drives the punching head 6 to continue deeper, the ring plate 7 also continues to move downwards. Since the clamping ring 9 is already fitted against the disc and cannot be pressed further down, the downward movement of the ring plate 7 compresses the spring 8, thereby increasing the elastic force of the spring 8. The spring 8 then pushes the clamping ring 9 to tightly and firmly press the disc, thus ensuring the disc is stably fixed in the forming cavity 3. After the disc is fully fixed, the punching head 6 also extends into the forming cavity 3, and through the forming... The cavity passes through the center of the disc, forming a ring in the groove. This punches a hole in the disc to form a gasket. After the punching head 6 passes through the center of the disc, the remaining disc material falls directly into the cavity 11 through the cavity 3. The remaining material slides to the left on the inclined surface of the cavity 11 and enters the collection box 12 for storage. This allows for timely and automatic discharge of the remaining material and proper collection for subsequent recycling. This is the working principle of the gasket punching equipment with automatic positioning compensation.
