Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, specifically to an automatic clamping device for automated material processing. Background Technology
[0002] Automated manufacturing integrates mechanical, electronic and computer technologies to achieve intelligent control of the production process. Its core objectives are to improve efficiency, accuracy and safety. In the process of automating material processing, it is necessary to clamp the material to facilitate its positioning or transfer.
[0003] Existing gripping devices generally use mechanical grippers. However, mechanical grippers are generally only suitable for materials of the same shape. For cylindrical materials, the grippers need to be replaced. For irregular materials, corresponding grippers need to be customized according to the characteristics of the irregular materials, which increases the cost and requires repeated replacement of grippers. Therefore, further improvements are needed. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides the following technical solution: an automatic gripping device for automated material processing, comprising a slide rail base, a lead screw rotatably connected inside the slide rail base, a servo motor for driving the lead screw fixedly installed at the end of the slide rail base, a slider slidably connected inside the slide rail base, and the lead screw screw screwed into the slider. A telescopic rod is fixedly installed on the bottom side of the slider, and a connecting seat is fixedly installed at the bottom end of the telescopic rod. A gripper assembly for gripping materials is provided at the bottom of the connecting seat. By activating the servo motor, the lead screw rotates inside the slider, thus causing the slider to slide along the inner wall of the slide rail base, thereby moving the gripper assembly to a designated location, facilitating the gripping and movement of materials.
[0005] As an optimization, the gripper assembly includes a housing fixedly installed at the bottom of the connecting seat. U-shaped plates are slidably connected to both sides of the interior of the housing. A top plate is fixedly installed on the top of the U-shaped plates. A dual-axis cylinder is fixedly installed in the middle of the housing, with both ends of the telescopic shaft of the dual-axis cylinder fixedly installed between the two top plates. A guide rod is fixedly installed in the top of the housing, and the top plate is slidably sleeved on the outside of the guide rod. A shaft is fixedly installed at the bottom of the U-shaped plates. A clamping plate is rotatably connected to the outside of the shaft and located inside the bottom of the U-shaped plates. A positioning element for locking and restricting the clamping plate is provided in the top of the U-shaped plates. Activating the dual-axis cylinder will cause the top plates on both sides to slide relative to each other, thereby causing the clamping plates on both sides to move closer together for clamping or move away for release, thus facilitating the gripping of materials.
[0006] As an optimization, the positioning component includes an inclined plate fixedly installed on the top of the clamping plate. The inclined plate and the top of the U-shaped plate are hinged with a self-locking cylinder with a self-locking function. By activating the self-locking cylinder, the inclined plate will be pushed and pulled, which will drive the clamping plate to deflect, making it convenient to clamp materials with sharp edges on the side.
[0007] As an optimization, a slot is provided in the middle of the top side of the clamping plate, and a support plate is rotatably connected to the outer side of the shaft located in the slot. A locking element is provided between the support plate and the shaft to lock and position the support plate. By rotating the support plate and the clamping plate to form an angle, it is convenient to clamp cylindrical and square materials.
[0008] As an optimization, the clamping plate has a sliding hole inside, and a locking block is slidably inserted into the sliding hole. A spring is fixedly installed between the locking block and the bottom wall of the sliding hole. The spring's own elasticity will drive the locking block to press against the surface of the material being clamped, thereby clamping and fixing it along the uneven shape of the material surface.
[0009] As an optimization, the locking component includes a rotating cylinder fixedly installed at the bottom of the support plate, and the rotating cylinder is rotatably connected to the outside of the shaft. A fixed cylinder is fixedly installed on the inner wall of the shaft, and an electric push rod is fixedly installed inside the fixed cylinder. A pressing plate is fixedly installed at the telescopic end of the electric push rod. By activating the electric push rod, the pressing plate can be driven to approach the shaft, thereby clamping it tightly against the outside of the shaft for locking.
[0010] As an optimization, a pad for increasing friction is provided on the bottom side of the extrusion plate, and the pad is made of carbon fiber.
[0011] The beneficial effects of this utility model are:
[0012] 1. The automatic clamping device for automated material processing uses a self-locking cylinder to push the inclined plate, which in turn causes the clamping plate to deflect inward around the shaft axis. Then, the support plate is turned inward, so that the clamping plate and the support plate are at an angle. The support plate is locked and positioned by a locking device, which makes it easy to clamp cylindrical, square and other materials with edges.
[0013] 2. The automatic clamping device for automated material processing, when the clamping plates on both sides approach and clamp the material, will cause the clamping block to contact the material surface, thereby compressing the spring. The spring's own elasticity will drive the clamping block to press against the surface of the material being clamped, thus clamping and fixing it along the uneven shape of the material surface, thereby improving the clamping tightness and making it suitable for clamping irregular materials.

[0020] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0021] 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.
[0022] Please see Figure 1An automatic gripping device for automated material processing includes a slide rail base 1, a lead screw 2 rotatably connected inside the slide rail base 1, a servo motor for driving the lead screw 2 fixedly installed at the end of the slide rail base 1, a slider 3 slidably connected inside the slide rail base 1, and the lead screw 2 screwed into the inside of the slider 3. A telescopic rod 4 is fixedly installed on the bottom side of the slider 3, and a connecting seat 5 is fixedly installed at the bottom end of the telescopic rod 4. A gripper assembly 6 for gripping materials is provided at the bottom of the connecting seat 5. By starting the servo motor, the lead screw 2 will rotate inside the slider 3, which will drive the slider 3 to slide along the inner wall of the slide rail base 1, thereby moving the gripper assembly 6 to a designated location, thus facilitating the gripping and movement of materials.
[0023] Please see Figure 2-3 The gripper assembly 6 includes a housing 7 fixedly installed at the bottom of the connecting seat 5. U-shaped plates 8 are slidably connected to both sides of the inside of the housing 7. A top plate 9 is fixedly installed on the top of the U-shaped plate 8. A dual-axis cylinder 10 is fixedly installed in the middle of the housing 7. The two ends of the telescopic shaft of the dual-axis cylinder 10 are fixedly installed between the two top plates 9. A guide rod 11 is fixedly installed in the top of the housing 7. The top plate 9 is slidably sleeved on the outside of the guide rod 11. A shaft 12 is fixedly installed at the bottom of the U-shaped plate 8. A clamping plate 13 is rotatably connected to the outside of the shaft 12 and located in the bottom of the U-shaped plate 8. A positioning element for locking and restricting the clamping plate 13 is provided in the top of the U-shaped plate 8. By activating the dual-axis cylinder 10, the top plates 9 on both sides will slide relative to each other, which will cause the clamping plates 13 on both sides to move closer to each other for clamping or move away from each other for release, thereby facilitating the clamping of materials.
[0024] Please see Figure 2-3 The positioning component includes an inclined plate 14 fixedly installed on the top of the clamping plate 13. The inclined plate 14 and the top of the U-shaped plate 8 are hinged to a self-locking cylinder 15 with a self-locking function. By activating the self-locking cylinder 15, the inclined plate 14 will be pushed and pulled, which will drive the clamping plate 13 to deflect, making it convenient to clamp materials with sharp edges on the side.
[0025] Please see Figure 3-4 A slot is provided in the middle of the top side of the clamping plate 13. A support plate 16 is rotatably connected to the outer side of the shaft 12 located in the slot. A locking element is provided between the support plate 16 and the shaft 12 for locking and positioning the support plate 16. By rotating the support plate 16 around the shaft 12, the support plate 16 and the clamping plate 13 can be made to form an angle, which facilitates the clamping of cylindrical and square materials.
[0026] Please see Figure 4The clamping plate 13 has a sliding hole inside, and a locking block 17 is slidably inserted into the sliding hole. A spring 18 is fixedly installed between the locking block 17 and the bottom wall of the sliding hole. The spring 18 will drive the locking block 17 to press against the surface of the material being clamped by its own elastic force, so that it can clamp and fix the material along the uneven shape of the material surface, improve the clamping tightness, and be suitable for clamping irregular materials.
[0027] Please see Figure 5 The locking component includes a rotating cylinder 19 fixedly installed at the bottom of the support plate 16, and the rotating cylinder 19 is rotatably connected to the outside of the shaft 12. A fixed cylinder 20 is fixedly installed on the inner wall of the shaft 12, and an electric push rod 21 is fixedly installed inside the fixed cylinder 20. A pressing plate 22 is fixedly installed at the telescopic end of the electric push rod 21. A pad for increasing friction is provided on the bottom side of the pressing plate 22, and the pad is made of carbon fiber. By activating the electric push rod 21, the pressing plate 22 can be driven to approach the shaft 12, and then it will be tightly clamped on the outside of the shaft 12 for locking. Therefore, the rotation of the rotating cylinder 19 is restricted, thereby locking and positioning the support plate 16.
[0028] In use, by starting the servo motor to drive the lead screw 2 to rotate inside the slider 3, the slider 3 can be driven to slide along the inner wall of the slide rail seat 1, which facilitates the movement of the gripper assembly 6 below to the designated location. Then, the telescopic rod 4 drives the gripper assembly 6 downward to approach the material to be gripped. Then, the dual-axis cylinder 10 drives the U-shaped plates 8 on both sides to approach each other, so that the clamping plate 13 can grip the material. After that, it moves with the gripper assembly 6 to the position where it needs to be processed.
[0029] By activating the self-locking cylinder 15 to push the inclined plate 14, the clamping plate 13 will be driven to deflect inward around the shaft 12. Then, the support plate 16 will be turned inward, so that the clamping plate 13 and the support plate 16 are at an angle. At this time, it is convenient to clamp cylindrical, square and other materials with edges. At the same time, the spring 18 will drive the locking block 17 to abut against the surface of the clamped material, so that it can be clamped and fixed along the uneven shape of the material surface, improving the clamping tightness.
[0030] In summary, the automatic clamping device for automated material processing, by activating the self-locking cylinder 15 to push the inclined plate 14, will cause the clamping plate 13 to deflect inward around the shaft 12, and then turn the support plate 16 inward, so that the clamping plate 13 and the support plate 16 are at an angle, and the support plate 16 is locked and positioned by the locking member, thus making it convenient to clamp cylindrical, square and other materials with edges.
[0031] When the clamping plates 13 approach the material, the locking block 17 contacts the material surface, which in turn compresses the spring 18. The spring 18's own elasticity causes the locking block 17 to press against the surface of the material, thus clamping and fixing it along the uneven shape of the material surface, thereby improving the clamping tightness and making it suitable for clamping irregular materials.
