Description

Technical Field

[0001] This utility model belongs to the field of automated operation technology, specifically relating to a clamping device with dual-station switching. Background Technology

[0002] In automated processing of shaft products, the single-jaw gripper mode is mainly used for picking up and unloading materials. Specifically, in the single-jaw mode, the processing equipment needs to rely entirely on the gripper to complete the "finished product removal" before it can enter the "processed product placement" stage. This creates an intermittent cycle of processing completion, gripper action, and processing start, resulting in wasted actions in multiple stages, leading to low equipment utilization and limited production capacity.

[0003] Existing technologies utilize robotic arms to drive two identical grippers for position switching. This involves connecting both the first and second gripper mechanisms to the drive end of the robotic arm, which then drives the first and second gripper mechanisms to switch positions. However, in practical applications, it has been found that debugging the robotic arm is quite complex, and it is difficult to ensure the accuracy after position switching. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this utility model provides a dual-station switching clamping device that enables material handling and loading / unloading at the same location, ensuring that the relative positions of the first and second clamping mechanisms remain unchanged after switching, thereby effectively improving work efficiency and accuracy.

[0005] The technical effects to be achieved by this utility model are realized through the following technical aspects: This utility model provides a clamping device with dual-station switching, including a mounting frame, on which a rotary drive mechanism is provided, and the drive end of the rotary drive mechanism is connected to a first mounting base, on which a first clamping mechanism and a second clamping mechanism are provided. It also includes a limiting mechanism, which includes a limiting movable block and a limiting fixed module. The limiting movable block is connected to the drive end of the rotary drive mechanism, and the limiting fixed module is disposed on the mounting frame and located on the rotational movement path of the limiting movable block, and is used to limit the rotation angle of the limiting movable block.

[0006] In some implementations, the limiting and fixing module includes a mounting plate, a first limiting rod assembly, and a second limiting rod assembly; The mounting plate is disposed on the mounting frame. The first limiting rod assembly and the second limiting rod assembly are respectively disposed at the upper end and the lower end of the mounting plate, and are used to abut and limit the limiting movable block in the forward rotation and reverse rotation directions, respectively, so as to ensure the accuracy of the position switching of the first clamping mechanism and the second clamping mechanism, thereby improving the accuracy of the operation.

[0007] In some implementations, the first limiting rod assembly includes a first limiting screw and a second limiting screw arranged adjacent to each other; The first limiting screw and the second limiting screw are adjustablely mounted on the mounting plate to adjust the distance between the first limiting screw and the limiting movable block, and between the second limiting screw and the limiting movable block, in accordance with the rotation angle requirements of the limiting movable block.

[0008] In some implementations, the rotary drive mechanism includes a linear drive cylinder, a first connecting rod, and a rotating shaft; The linear drive cylinder is mounted on the mounting bracket, the first connecting rod is connected to the drive end of the linear drive cylinder, and a transmission gear is mounted on the rotating shaft, with the first connecting rod meshing with the transmission gear. The first mounting base and the limiting movable block are respectively connected to the two ends of the rotating shaft to realize the synchronous rotation of the first mounting base and the limiting movable block.

[0009] In some implementations, the mounting bracket is provided with a first sliding groove, and the first connecting rod passes through the first sliding groove. The first sliding groove guides and limits the movement of the first connecting rod, thereby improving the accuracy of its position movement.

The hydraulic gear drive improves the clamping force of the first clamping arm and the second clamping arm, thereby ensuring the stability of material handling.

[0012] In some implementations, a first contour block is connected to the side of the first clamping arm facing the second clamping arm; The second clamping arm has a second contour block connected to the side facing the first clamping arm. The first and second contour blocks are used to match the shape of the product being clamped in order to improve clamping stability.

[0013] In some implementations, grooves are formed on both the first and second contour blocks; The groove is a V-shaped groove, which is suitable for picking up and putting down shaft products.

They are only for the convenience of describing this invention and simplifying the description, and do not 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 invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] Example 1: Please see Figures 1-4 A dual-station switching clamping device includes a mounting frame 100, on which a rotary drive mechanism 200 is mounted. The drive end of the rotary drive mechanism 200 is connected to a first mounting base 300. The first mounting base 300 is equipped with a first clamping mechanism 400 and a second clamping mechanism 500. Both the first clamping mechanism 400 and the second clamping mechanism 500 can perform material handling. For example, at the first station, materials that have been processed need to be removed and materials to be processed need to be placed in; at the second station, materials to be processed need to be removed to the first station, and materials that have been processed at the first station need to be placed in the second station for unloading. That is, for both the first and second stations, there are material handling operations, and the first clamping mechanism 400 and the second clamping mechanism 500 move simultaneously to the first or second station to perform switching operations.

[0022] In one example, there is material with completed work at the first workstation, and the second clamping mechanism 500 clamps the material to be worked on. When the clamping device moves above the first workstation under the action of external driving force, the first clamping mechanism 400 is positioned at the upper end of the first workstation. The first clamping mechanism 400 removes the material with completed work at the first workstation. Then, the rotation drive mechanism 200 drives the first mounting base 300 to rotate, that is, to switch the positions of the first clamping mechanism 400 and the second clamping mechanism 500, so that the second clamping mechanism 500 is positioned at the upper end of the first workstation, and the material to be worked on is placed on the first workstation.

[0023] The clamping device also includes a limiting mechanism 600, which includes a limiting movable block 610 and a limiting fixing module 620. The limiting movable block 610 is connected to the drive end of the rotary drive mechanism 200, and the limiting fixing module 620 is disposed on the mounting frame 100 and located on the rotational movement path of the limiting movable block 610, and is used to limit the rotation angle of the limiting movable block 610.

[0024] As is known, the drive end of the rotary drive mechanism 200 is connected to the first mounting base 300. Under the driving action of the rotary drive mechanism 200, the first mounting base 300 can drive the first clamping mechanism 400 and the second clamping mechanism 500 to switch positions relative to the first workstation, that is, the same workstation. Here, the limiting movable block 610 is also connected to the drive end of the rotary drive mechanism 200. Therefore, under the rotary drive action of the rotary drive mechanism 200, the first mounting base 300 and the limiting movable block 610 rotate synchronously. In order to limit the rotation angle of the first mounting base 300, that is, to limit the rotation angle of the first clamping mechanism 400 and the second clamping mechanism 500, a limiting fixing module 620 is provided on the mounting frame 100. During the rotation, when the limiting movable block 610 abuts against the limiting fixing module 620, it indicates that the first mounting base 300 has rotated to the correct position, that is, the first clamping mechanism 400 and the second clamping mechanism 500 have switched to the correct position.

[0025] Understandably, under the driving action of the rotary drive mechanism 200, the first mounting base 300 and the limiting movable block 610 rotate in the forward direction. When the rotary drive mechanism 200 retracts, the first mounting base 300 and the limiting movable block 610 rotate in the reverse direction. The limiting fixing module 620 can abut and limit the limiting movable block 610 in both the forward and reverse rotation paths.

[0026] The clamping device provided in this embodiment is provided with a first mounting base 300 for fixing the positions of the first clamping mechanism 400 and the second clamping mechanism 500, ensuring that the relative positions of the first clamping mechanism 400 and the second clamping mechanism 500 remain unchanged after switching. Furthermore, by setting a limiting mechanism 600, the position switching accuracy of the first clamping mechanism 400 and the second clamping mechanism 500 is ensured, thereby effectively improving the operation accuracy.

[0027] In some embodiments, the limiting and fixing module 620 includes a mounting plate 621, a first limiting rod assembly 622, and a second limiting rod assembly 623. The mounting plate 621 is disposed on the mounting frame 100, and the first limiting rod assembly 622 and the second limiting rod assembly 623 are respectively disposed at the upper and lower ends of the mounting plate 621, respectively, for abutting and limiting the limiting movable block 610 in the forward rotation and reverse rotation directions, so as to ensure the accuracy of the position switching of the first clamping mechanism 400 and the second clamping mechanism 500, thereby improving the accuracy of the operation.

[0028] For example, the first limiting rod assembly 622 is located at the upper end of the mounting plate 621, and the second limiting rod assembly 623 is located at the lower end of the mounting plate 621. When the rotary drive mechanism 200 drives the first mounting base 300 and the limiting movable block 610 to rotate in the forward direction, the limiting movable block 610 abuts against the first limiting rod assembly 622. When the rotary drive mechanism 200 retracts, the first mounting base 300 and the limiting movable block 610 rotate in the reverse direction, and the limiting movable block 610 abuts against the second limiting rod assembly 623.

[0029] Preferably, the first limiting rod assembly 622 includes a first limiting screw 6221 and a second limiting screw 6222 arranged adjacent to each other; the first limiting screw 6221 and the second limiting screw 6222 are adjustablely disposed on the mounting plate 621, and the distance between the first limiting screw 6221 and the limiting movable block 610 and the second limiting screw 6222 and the limiting movable block 610 are adjusted in accordance with the rotation angle requirements of the limiting movable block 610.

[0030] The first limiting screw 6221 and the second limiting screw 6222 are used to synchronously abut against each other, which can improve the stability of the limit and prevent the limiting movable block 610 from shaking.

[0031] Example 2: This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-4 Based on the above, refer to Figure 5 and Figure 6 .

[0032] In this embodiment, the rotary drive mechanism 200 includes a linear drive cylinder 210, a first connecting rod 220, and a rotary shaft 230. The linear drive cylinder 210 is mounted on the mounting bracket 100, the first connecting rod 220 is connected to the drive end of the linear drive cylinder 210, and a transmission gear 240 is mounted on the rotary shaft 230. The first connecting rod 220 is meshed with the transmission gear 240. The first mounting seat 300 and the limiting movable block 610 are respectively connected to the two ends of the rotary shaft 230 to realize the synchronous rotation of the first mounting seat 300 and the limiting movable block 610.

[0033] Understandably, teeth are formed on the lateral surface of the first connecting rod 220 for meshing with the transmission gear 240. When the linear drive cylinder 210 drives the first connecting rod 220 to move downward, the teeth on the first connecting rod 220 drive the transmission gear 240 to rotate, thereby causing the rotating shaft 230 to drive the first mounting base 300 and the limiting movable block 610 to rotate, achieving a rotational drive effect.

[0034] In some embodiments, the mounting bracket 100 is provided with a first slide groove 110, and the first connecting rod 220 passes through the first slide groove 110. The first slide groove 110 guides and limits the movement of the first connecting rod 220, thereby improving the accuracy of its position movement.

[0035] Driven by the linear drive cylinder 210, the first connecting rod 220 moves linearly relative to the first slide groove 110, thereby improving the accuracy of the position movement of the first connecting rod 220.

[0036] Example 3: This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-4 Based on the above, refer to Figure 7 and Figure 8 .

[0037] In this embodiment, the first clamping mechanism 400 includes a first clamping drive module 410 and a first clamping module 420 connected to the drive end of the first clamping drive module 410. The first clamping drive module 410 drives the first clamping module 420 to pick up and put down the product, thereby achieving an automated operation effect.

[0038] Preferably, the first clamping drive module 410 includes a second mounting base 411, a second connecting rod 412, a first gear 413, and a second gear 414; the second mounting base 411 has a first mounting chamber, the second connecting rod 412 is disposed in the first mounting chamber, one end of the second connecting rod 412 is connected to an elastic element 415 for resetting, and the first mounting chamber is connected to an external hydraulic cylinder through a first interface 416; the first clamping module 420 includes a first clamping arm 421 and a second clamping arm 422, the first clamping arm 421 being connected to a first clamping arm 413 and a second clamping arm 414. A first rack 423 and a second clamping arm 422 are connected to a second rack 424. A first gear 413, a first rack 423, a second gear 414, and a second rack 424 are arranged sequentially from top to bottom in a second mounting base 411. The first gear 413 meshes with the second connecting rod 412 and the first rack 423, and the second gear 414 meshes with the first rack 423 and the second rack 424. The hydraulic gear drive method is used to improve the clamping force of the first clamping arm 421 and the second clamping arm 422, thereby ensuring the stability of material handling.

[0039] refer to Figure 8During the actual operation, under the pressure of the external hydraulic cylinder, the second connecting rod 412 moves to the left. The elastic element 415 is stretched by the second connecting rod 412, resulting in tensile deformation. During the leftward movement of the second connecting rod 412, it drives the first gear 413 to rotate counterclockwise. The first gear 413 drives the first rack 423 to move to the right. The first rack 423 drives the second gear 414 to rotate clockwise. The second gear 414 drives the second rack 424 to move to the left, that is, the first clamping arm 421 and the second clamping arm 422 move closer to each other. This achieves the clamping effect on the material; conversely, when the pressure of the external hydraulic cylinder disappears, the elastic element 415 resets, driving the second connecting rod 412 to move to the right. During the movement of the second connecting rod 412 to the right, it drives the first gear 413 to rotate clockwise. The first gear 413 drives the first rack 423 to move to the left. The first rack 423 drives the second gear 414 to rotate counterclockwise. The second gear 414 drives the second rack 424 to move to the right. That is, the first clamping arm 421 and the second clamping arm 422 move away from each other, achieving the release effect on the material.

[0040] In this embodiment, a hydraulic gear drive is used to clamp the material, which can provide a large clamping force, improve the clamping stability of the material, and prevent the material from falling off.

[0041] In some embodiments, a first contour block 425 is connected to the side of the first clamping arm 421 facing the second clamping arm 422; a second contour block 426 is connected to the side of the second clamping arm 422 facing the first clamping arm 421. The first contour block 425 and the second contour block 426 are used to match the shape of the product being clamped in order to improve clamping stability.

[0042] Preferably, both the first contour block 425 and the second contour block 426 have grooves 427 formed on them; the grooves 427 are V-shaped grooves 427, which are suitable for picking up and putting down shaft products.

[0043] In some embodiments, the first clamping arm 421 is provided with a limiting component 700 for limiting the installation height of the first profile block 425. The limiting component 700 limits the installation height of the first profile block 425, thereby improving the installation accuracy.

[0044] For example, the limiting component 700 can be a screw and a limiting seat. The limiting seat is set on the first clamping arm 421 and located at the upper end of the first contour block 425. The screw is screwed into the limiting seat and the lower end of the screw protrudes from the limiting seat and abuts against the upper end of the first contour block 425, thereby limiting the installation height of the first contour block 425.

[0045] Understandably, the second clamping arm is also equipped with a limiting component for limiting the installation height of the second profilograph block.

[0046] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
