[0003] A clamping device for a multi-station cold heading machine with rapid positioning disclosed in Chinese Patent CN208960882U includes a base, a fixed moving platform at the upper end of the base, a limit ring at the lower end of the base, a second fixing bolt connected to the limit ring, a collar at the position between the fixed moving platform and the limit ring on the base, a rotating platform at the bottom end of the base, a first connecting frame connected to one side of the lower surface of the rotating platform, a second connecting frame with the same components as the first connecting frame provided on the other side of the lower surface of the rotating platform, a first clamp connected to one side of the second connecting frame, and a second clamp connected to one side of the first connecting frame.

[0004] This gripping device uses multiple gripper heads to grip the product. However, when stacking products, if only one product can be placed at a time due to the large number of products, the work efficiency is low.

[0005] To solve the above problems, this utility model proposes a multi-station clamping device mechanism. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a multi-station clamping device mechanism.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: including a base plate, on the top of which a first cylinder and a second cylinder are fixedly mounted, and a first mounting plate is fixedly provided at the output end of the first cylinder, and a plurality of first grippers are fixedly connected at intervals at the bottom of the first mounting plate.

[0008] The output end of the second cylinder is fixedly provided with a second mounting plate, and a number of fixed plates are fixedly connected at intervals to the bottom of the second mounting plate. Each fixed plate has a second gripper horizontally slidably connected to one side by a spring.

[0009] The number of the second gripper is equal to that of the first gripper and they correspond one-to-one. The second gripper is movably positioned between two adjacent first grippers.

[0010] Furthermore, a first connecting plate is fixedly connected to the output end of the first cylinder, a first sliding plate is fixedly connected to the bottom of the first connecting plate, the first sliding plate slides horizontally through the bottom plate, and a first mounting plate is fixedly connected to the bottom of the first sliding plate.

[0011] Furthermore, a second connecting plate is fixedly connected to the output end of the second cylinder, and a second sliding plate is fixedly connected to the bottom of the second connecting plate. The second sliding plate slides horizontally through the bottom plate, and a second mounting plate is fixedly connected to the bottom of the second sliding plate.

[0012] Furthermore, the bottom of the base plate is symmetrically fixedly connected to two slide rails, which correspond one-to-one with the first mounting plate and the second mounting plate respectively.

[0013] Two sliders are fixedly connected to the top of both the first and second mounting plates, and the top ends of the sliders are slidably mounted on corresponding slide rails.

[0014] Furthermore, a buffer plate is fixedly connected to the top of each of the second grippers, one end of the spring is fixedly connected to one side of the fixed plate, and the other end of the spring is fixedly connected to one side of the corresponding buffer plate.

[0015] Two sliding rods are symmetrically fixedly connected to one side of each fixed plate, and two linear bearings are fixedly passed through each buffer plate. The linear bearings correspond one-to-one with the sliding rods, and the linear bearings are slidably sleeved on the corresponding sliding rods.

[0016] Furthermore, two first fixed seats are symmetrically fixedly connected to the top of the base plate, and a first hydraulic buffer is fixedly inserted through each of the two first fixed seats.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The multi-station gripping device is equipped with several first grippers and several second grippers. In use, the first mounting plate is moved by the first cylinder, causing the several first grippers to move horizontally. The second mounting plate is moved by the second cylinder, causing the several second grippers to move horizontally. The distance between the corresponding first grippers and second grippers is adjusted, so that all the first grippers and the corresponding second grippers cooperate to grip multiple products together, thereby improving work efficiency.

[0020] 2. The multi-station clamping device is equipped with a buffer plate. The buffer plate is connected to the fixed plate by a spring. When the first and second clamps move to clamp the product, after the second clamp contacts the product, the fixed plate continues to move, causing the slide bar to pass through the buffer plate and compress the spring. The spring pushes the buffer plate to fix the second clamp to the product, so that the clamping force between the first and second clamps is dynamically changing, which fixes the product without causing damage.

[0029] 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.

[0030] like Figures 1-7 As shown, the technical solution adopted by this utility model is as follows: a multi-station clamping device mechanism, including a base plate 1, and a first cylinder 2 and a second cylinder 9 are fixedly installed on the top of the base plate 1.

[0031] A first mounting plate 5 is fixedly installed at the output end of the first cylinder 2, and a number of first grippers 7 are fixedly connected at intervals to the bottom of the first mounting plate 5. The number of first grippers 7 are arranged in a straight line.

[0032] The output end of the first cylinder 2 is fixedly connected to a first connecting plate 3, and the bottom of the first connecting plate 3 is fixedly connected to a first sliding plate 4. The first sliding plate 4 slides horizontally through the base plate 1, and a first mounting plate 5 is fixedly connected to the bottom of the first sliding plate 4. The first mounting plate 5 is located below the base plate 1. The output end of the first cylinder 2 pushes the first connecting plate 3, which in turn moves the first mounting plate 5 via the first sliding plate 4.

[0033] A second mounting plate 12 is fixedly installed at the output end of the second cylinder 9.

[0034] The output end of the second cylinder 9 is fixedly connected to the second connecting plate 10, and the bottom of the second connecting plate 10 is fixedly connected to the second sliding plate 11. The second sliding plate 11 slides horizontally through the base plate 1, and the second mounting plate 12 is fixedly connected to the bottom of the second sliding plate 11. The output end of the second cylinder 9 pushes the second connecting plate 10, which in turn drives the second mounting plate 12 to move via the second sliding plate 11.

[0035] Two slide rails 6 are symmetrically fixedly connected to the bottom of the base plate 1. The two slide rails 6 correspond one-to-one with the first mounting plate 5 and the second mounting plate 12 respectively.

[0036] Two sliders 8 are fixedly connected to the top of both the first mounting plate 5 and the second mounting plate 12. The top ends of the sliders 8 are slidably mounted on corresponding slide rails 6. By sliding the sliders 8 on the slide rails 6, the first mounting plate 5 and the second mounting plate 12 move along the slide rails 6, thus positioning the movement of the first mounting plate 5 and the second mounting plate 12.

[0037] The bottom of the second mounting plate 12 is fixedly connected with several fixing plates 13 at intervals, and each fixing plate 13 has a second clamping claw 15 horizontally slidably connected to one side by a spring 17.

[0038] The number of second grippers 15 is equal to that of the first grippers 7, and they correspond one-to-one. The second grippers 15 are movably positioned between two adjacent first grippers 7. This allows the corresponding first grippers 7 and second grippers 15 to cooperate and grip multiple products together.

[0039] Each second gripper 15 has a buffer plate 14 fixedly connected to its top. One end of a spring 17 is fixedly connected to one side of a fixed plate 13, and the other end of the spring 17 is fixedly connected to one side of the corresponding buffer plate 14. In the initial state, the spring 17 pushes the buffer plate 14 to maximize the distance between the buffer plate 14 and the fixed plate 13.

[0040] Two slide rods 16 are symmetrically fixed to one side of each fixed plate 13. Two linear bearings are fixedly threaded through each buffer plate 14. The linear bearings correspond one-to-one with the slide rods 16, and the linear bearings are slidably sleeved on the corresponding slide rods 16. The buffer plate 14 is positioned by the two slide rods 16, so that the buffer plate 14 can only move along the slide rods 16.

[0041] Two first fixed seats 18 are symmetrically fixedly connected to the top of the base plate 1, and a first hydraulic buffer 19 is fixedly inserted through each of the two first fixed seats 18. The telescopic end of one of the first hydraulic buffers 19 is movably located on one side of the first connecting plate 3. The telescopic end of the other first hydraulic buffer 19 is movably located on one side of the second connecting plate 10.

[0042] A second fixed seat 20 is fixedly connected to the side of the first cylinder 2 and the second cylinder 9 that is away from each other. A second hydraulic damper 21 is fixedly inserted through each of the two second fixed seats 20. The telescopic end of one of the second hydraulic dampers 21 is slidably disposed on the other side of the first connecting plate 3. The telescopic end of the other second hydraulic damper 21 is movably disposed on the other side of the second connecting plate 10. The function of the hydraulic damper is to reduce vibration and noise in automated mechanical operations, convert the kinetic energy generated by a moving object into heat energy and release it into the atmosphere, and effectively stop the object in balance during operation. The hydraulic damper is an existing product.

[0043] Working principle:

[0044] When in use, mount the base plate 1 onto the robotic arm.

[0045] Start the first cylinder 2 and the second cylinder 9. The output end of the first cylinder 2 pushes the first connecting plate 3 to move to the left, and the output end of the second cylinder 9 pushes the second connecting plate 10 to move to the right.

[0046] The first connecting plate 3 drives the first sliding plate 4 to slide on the base plate 1, causing the first mounting plate 5 to move below the base plate 1. At the same time, the slider 8 on the top of the first mounting plate 5 slides on the corresponding slide rail 6, driving several first grippers 7 to move synchronously.

[0047] The second connecting plate 10 drives the second sliding plate 11 to slide on the base plate 1, causing the second mounting plate 12 to move below the base plate 1. At the same time, the slider 8 on the top of the second mounting plate 12 slides on the corresponding slide rail 6, driving several fixed plates 13, buffer plates 14, and second grippers 15 to move.

[0048] Maximize the distance between the corresponding first gripper 7 and second gripper 15. Move the base plate 1 to the product to be gripped using a robotic arm, so that the product is positioned between the corresponding first gripper 7 and second gripper 15.

[0049] The output end of the first cylinder 2 pushes the first connecting plate 3 to move to the right, and the output end of the second cylinder 9 pushes the second connecting plate 10 to move to the left.

[0050] The first connecting plate 3 drives the first gripper 7 to move horizontally, and the second connecting plate 10 drives the second gripper 15 to move horizontally, so that the corresponding first gripper 7 and second gripper 15 move closer to each other.

[0051] After the second gripper 15 contacts the product, the fixing plate 13 continues to move, causing the slide bar 16 to slide on the buffer plate 14 and compressing the spring 17. The spring 17 exerts a pushing force on the buffer plate 14, which causes the second gripper 15 to abut against the product, simultaneously working with the first gripper 7 to clamp and fix the product. Because the buffer plate 14 can slide on the slide bar 16, the clamping force between the first gripper 7 and the second gripper 15 is dynamically changing, fixing the product without causing damage.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
