Description

Technical Field

[0001] This utility model relates to the field of stamping robot technology, specifically a stamping robot for stamping the inner panel of an automobile trunk lid. Background Technology

[0002] The production process of the inner panel of a car trunk lid typically involves the use of molds. Stamping dies are special process equipment used in cold stamping to process materials into parts; they are commonly known as cold stamping dies. Stamping is a pressure processing method that uses a mold mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts. However, before and after stamping, a stamping robot is needed to perform tasks such as loading and unloading materials into the mold.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Existing stamping robots typically use suction cup robots. Since the inner panel of a car trunk lid is a curved workpiece, it is easy for the suction cup to form an angle with the workpiece surface, which leads to significant safety hazards during workpiece handling. Therefore, we propose a stamping robot for stamping the inner panel of a car trunk lid to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stamping robot for stamping the inner panel of an automobile trunk lid. This solves the problem that suction cup robots easily create an angle between the suction cup and the workpiece surface when handling curved workpieces, leading to significant safety hazards during workpiece handling.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a stamping robot for stamping inner panels of car trunk lids, comprising a base, a first motor mounted on the top of the base, a hydraulic rod fixedly mounted on the output end of the first motor, a top frame fixedly mounted on the output end of the hydraulic rod, a rectangular groove formed on the inner wall of the top frame, and a sliding groove formed on the bottom of the top frame, a transmission block slidably connected to the inner wall of the sliding groove, and a bracket fixedly mounted on the bottom of the transmission block and located at the bottom of the top frame;

A third motor is fixedly installed on one side of the bracket, and a bidirectional screw is rotatably connected to the bottom of the bracket. The output end of the third motor is fixedly connected to the bidirectional screw, and buffer components are installed on the inner sides of the two clamping blocks.

[0007] Preferably, the bottom of the left end of the top frame is fixedly connected to the output end of the hydraulic rod, and the transmission block is slidably connected in the groove through a threaded rod.

[0008] Preferably, one end of the threaded rod extends into the rectangular groove, and the output end of the second motor is fixedly connected to one end of the threaded rod.

[0010] Preferably, the inner walls of both clamping blocks are provided with threaded holes, and the bidirectional screws are respectively sleeved in the two threaded holes.

[0011] Preferably, the buffer assembly includes a limiting rod and a clamping plate.

[0013] Beneficial effects

[0014] This utility model provides a stamping robot for stamping the inner panel of an automobile trunk lid. Compared with the prior art, it has the following advantages:

[0015] 1. This stamping robot for the inner panel of a car trunk lid uses a hydraulic rod to push a top frame, which in turn moves the support and two clamping blocks up and down. A second motor drives a threaded rod to rotate, and under the action of the thread, the transmission block moves the support and two clamping blocks left and right along the slide groove. At the same time, a third motor drives a bidirectional screw to rotate, causing the two clamping blocks to slide along the bottom of the support. This allows the two clamping blocks to handle workpieces of different heights and widths, avoiding the safety hazards associated with suction cup robots handling curved workpieces, where the suction cup forms an angle with the workpiece surface.

[0016] 2. The stamping robot for the inner panel of the car trunk lid can avoid direct hard contact between the two clamping blocks and the workpiece, thus preventing workpiece deformation, through two buffer components. Attached Figure Description

[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] Please see Figure 1-4 This utility model provides a technical solution: a stamping robot for stamping the inner panel of a car trunk lid, including a base 1, a first motor 2 installed on the top of the base 1, a hydraulic rod 3 fixedly installed at the output end of the first motor 2, a top frame 4 fixedly installed at the output end of the hydraulic rod 3, a rectangular groove 41 opened on the inner wall of the top frame 4, and a sliding groove 42 opened at the bottom of the top frame 4, a transmission block 10 slidably connected to the inner wall of the sliding groove 42, and a bracket 5 fixedly installed at the bottom of the transmission block 10 and at the bottom of the top frame 4; a second motor 8 is installed inside the rectangular groove 41, a threaded rod 9 is rotatably connected inside the sliding groove 42, the transmission block 10 is sleeved on the outer wall of the threaded rod 9, and two clamping blocks 6 are slidably connected to the bracket 5, a third motor 11 is fixedly installed on one side of the bracket 5, a bidirectional screw 13 is rotatably connected to the bottom of the bracket 5, the output end of the third motor 11 is fixedly connected to the bidirectional screw 13, and buffer components 7 are installed on the inner side of each of the two clamping blocks 6.

[0024] The top frame 4 can be installed via the hydraulic rod 3, thereby activating the hydraulic rod 3 to push the top frame 4, causing the bracket 5 and the two clamping blocks 6 to move up and down. At the same time, the second motor 8 is activated to drive the threaded rod 9 to rotate. Under the action of the thread, the transmission block 10 drives the bracket 5 and the two clamping blocks 6 to move left and right along the slide groove 42. The third motor 11 is activated to drive the bidirectional screw 13 to rotate. Under the action of the thread, the two clamping blocks 6 are driven to slide along the bottom of the bracket 5. This allows the two clamping blocks 6 to handle workpieces of different heights and widths, avoiding the problem of suction cup robots handling curved workpieces. The suction cup and the workpiece surface are prone to forming an angle, which poses a significant safety hazard when handling workpieces. Furthermore, since the inner sides of the two clamping blocks 6 are equipped with buffer components 7, the two buffer components 7 can prevent the two clamping blocks 6 from directly contacting the workpiece and causing deformation.

[0025] See Figure 1 , Figure 2 The bottom of the left end of the top frame 4 is fixedly connected to the output end of the hydraulic rod 3. The transmission block 10 is slidably connected to the slide groove 42 through the threaded rod 9. One end of the threaded rod 9 passes through the rectangular groove 41, and the output end of the second motor 8 is fixedly connected to one end of the threaded rod 9.

[0026] The top frame 4 can be installed via the hydraulic rod 3. Since the output end of the second motor 8 is fixedly connected to one end of the threaded rod 9, the second motor 8 is started to drive the threaded rod 9 to rotate. Under the action of the thread, the transmission block 10 drives the bracket 5 and the two clamping blocks 6 to move left and right along the slide groove 42, thereby enabling the two clamping blocks 6 to transport the workpiece.

[0027] See Figure 2 , Figure 3 The bracket 5 is fixedly connected to the bottom of the transmission block 10, and the bottom of the bracket 5 is provided with a groove 12. The top of the two clamping blocks 6 is fixedly installed with protrusions 61, and the two protrusions 61 are slidably connected in the groove 12. The inner wall of the two clamping blocks 6 is provided with threaded holes, and the bidirectional screw 13 is respectively sleeved in the two threaded holes.

[0028] The bracket 5 can be installed via the transmission block 10. Since the third motor 11 is installed on the top of the bracket 5, the third motor 11 is started to drive the bidirectional screw 13 to rotate. Under the action of the threaded holes opened on the inner wall of the two clamping blocks 6, the two clamping blocks 6 drive the two protrusions 61 to slide along the inner wall of the groove 12, thereby enabling the two clamping blocks 6 to transport workpieces of different widths.

[0029] See Figure 1 , Figure 4The buffer assembly 7 includes a limiting rod 71 and a clamping plate 72. The limiting rod 71 is fixedly installed on the inner side of the clamping block 6, and two sliders 73 are slidably connected to the outer wall of the limiting rod 71. The top of the two sliders 73 is hinged to a connecting rod 74, and springs 75 are fixedly connected to the outer side of the two sliders 73. The other end of the two connecting rods 74 is hinged to the inner side of the clamping plate 72, and the other end of the two springs 75 is fixedly connected to the left and right ends of the limiting rod 71, respectively. A rubber pad 76 is provided on the outer side of the clamping plate 72.

[0030] The two sliders 73 and two springs 75 can be installed through the limiting rod 71 in the buffer assembly 7. Since the left and right ends of the connecting rod 74 are respectively hinged to the bottom of the two sliders 73 and the clamping plate 72, when the two clamping blocks 6 move the workpiece, the clamping plate 72 contacts the workpiece, and the workpiece will exert pressure on the clamping plate 72 outward. Under the action of pressure, the two sliders 73 slide in the opposite direction along the outer wall of the limiting rod 71. At this time, the two springs 75 are compressed, and the two connecting rods 74 rotate along the hinge point at the bottom of the sliders 73 and the clamping plate 72. Thus, through the elastic force of the two springs 75, the workpiece can be prevented from making direct hard contact with the clamping block 6, thus avoiding deformation of the workpiece. Since the outer side of the clamping plate 72 is provided with a rubber pad 76, the softness and elasticity of the rubber pad 76 can effectively reduce scratches and indentations caused during the workpiece clamping process, thus protecting the surface of the workpiece.

[0031] During operation, the top frame 4 can be installed via the hydraulic rod 3, thereby activating the hydraulic rod 3 to push the top frame 4, causing the support 5 and the two clamping blocks 6 to move up and down. Simultaneously, the second motor 8 is activated to drive the threaded rod 9 to rotate. Under the action of the thread, the transmission block 10 drives the support 5 and the two clamping blocks 6 to move left and right along the slide groove 42. At the same time, the third motor 11 is activated to drive the bidirectional screw 13 to rotate. Under the action of the thread, the two clamping blocks 6 are driven to slide along the bottom of the support 5. This allows the two clamping blocks 6 to handle workpieces of different heights and widths, avoiding the problem of suction cup robots handling curved workpieces. The suction cup and the workpiece surface are prone to forming an angle, which poses a significant safety hazard during workpiece handling. Furthermore, since the inner sides of the two clamping blocks 6 are equipped with buffer components 7, the two buffer components 7 can prevent the two clamping blocks 6 from directly contacting the workpiece and causing deformation.

[0032] The top frame 4 can be installed via the hydraulic rod 3. Since the output end of the second motor 8 is fixedly connected to one end of the threaded rod 9, the second motor 8 is started to drive the threaded rod 9 to rotate. Under the action of the thread, the transmission block 10 drives the bracket 5 and the two clamping blocks 6 to move left and right along the slide groove 42, thereby enabling the two clamping blocks 6 to transport the workpiece.

[0033] The bracket 5 can be installed via the transmission block 10. Since the third motor 11 is installed on the top of the bracket 5, the third motor 11 is started to drive the bidirectional screw 13 to rotate. Under the action of the threaded holes opened on the inner wall of the two clamping blocks 6, the two clamping blocks 6 drive the two protrusions 61 to slide along the inner wall of the groove 12, thereby enabling the two clamping blocks 6 to transport workpieces of different widths.

[0034] The two sliders 73 and two springs 75 can be installed through the limiting rod 71 in the buffer assembly 7. Since the left and right ends of the connecting rod 74 are respectively hinged to the bottom of the two sliders 73 and the clamping plate 72, when the two clamping blocks 6 move the workpiece, the clamping plate 72 contacts the workpiece, and the workpiece will exert pressure on the clamping plate 72 outward. Under the action of pressure, the two sliders 73 slide in the opposite direction along the outer wall of the limiting rod 71. At this time, the two springs 75 are compressed, and the two connecting rods 74 rotate along the hinge point at the bottom of the sliders 73 and the clamping plate 72. Thus, through the elastic force of the two springs 75, the workpiece can be prevented from making direct hard contact with the clamping block 6, thus avoiding deformation of the workpiece. Since the outer side of the clamping plate 72 is provided with a rubber pad 76, the softness and elasticity of the rubber pad 76 can effectively reduce scratches and indentations caused during the workpiece clamping process, thus protecting the surface of the workpiece.

[0035] In summary, the device starts the third motor 11 to drive the bidirectional screw 13 to rotate, which drives the two clamping blocks 6 to slide along the bottom of the bracket 5. This allows the two clamping blocks 6 to transport workpieces of different widths, avoiding the problem of suction cup robots transporting curved workpieces, where the suction cup and the workpiece surface form an angle, resulting in a significant safety hazard during workpiece transport.
