Technical Field

[0001] The present invention relates to the technical field of mechanical devices, and particularly to a mechanical gripper device. Background Art

[0002] During the production and manufacturing process of products, it is necessary to grasp the products and place them at appropriate process positions to replace manual labor, reduce labor costs, and prevent human errors.

[0003] For example, in the invention patent disclosed with the publication number: CN 211761628 U, a mechanical gripper includes: a main beam; a flange fixed in the middle of one side of the main beam, and the flange can be fixedly connected to the six-axis of a robot; several jaw mechanisms are fixedly arranged at intervals on the other side of the main beam; the jaw mechanism includes: a fixed frame, one end wall of which is fixed on the other side of the main beam; a floating adjustment component, one end of which is telescopically and movably connected to the other end wall of the fixed frame

[0004] However, the above gripper device fails to achieve simultaneous lateral and longitudinal separation of the gripper to grasp multiple products, and the grasping efficiency is low. Therefore, there is an urgent need for a mechanical gripper device that can grasp multiple products simultaneously. Summary of the Invention

[0005] Based on this, in view of the problem of simultaneous grasping, it is necessary to provide a mechanical gripper device.

[0006] To achieve the above object, the present invention provides the following technical solution: A mechanical gripper device includes a substrate. On both sides of the top of the substrate, support plates are respectively fixedly connected. A suspension plate is fixedly connected between the two support plates, and the suspension plate is used to connect with an external ceiling to fixedly support the entire device. A number of stretching and fixing rivets are arranged on the support plates, which are used for fixing the device and can also play a role in stretching and supporting. On one side directly below the substrate, an anti-wear block is fixedly connected, and the anti-wear block plays a role in preventing excessive friction and wearing out the device. On both sides below the substrate, annular support rods are respectively fixedly connected, and a power rod is rotatably connected between the two annular support rods, and the power rod provides the primary power for the entire device.

[0007] In one embodiment, three first guide plates are fixedly connected directly below the substrate. The first guide plates are arranged horizontally, and four second guide plates are arranged below the first guide plates. The second guide plates are arranged vertically.

[0008] In one embodiment, a first track is fixedly connected below each first guide rail plate. A connecting shaft is embedded and slidably connected on the first track. The connecting shaft is fixedly connected to the second guide rail plate. The connecting shaft can drive the second guide rail plate to slide on the first track, realizing the horizontal and vertical separation of the mechanical gripper. The second guide rail plate is connected to the substrate through a tensile fixed rivet, which can play a role in supporting and stretching the second guide rail plate during displacement. A second track is fixedly connected below the second guide rail plate.

[0009] In one embodiment, buffer fixing plates are fixedly connected to both sides of the second guide rail plate. A buffer rod is fixedly connected to the inner side of the buffer fixing plate.

[0010] In one embodiment, a sliding block is embedded and slidably connected below each second track. An elastic connector is connected between the two sliding blocks at the central position. Through the action of the connector, each sliding block can be displaced horizontally and vertically.

[0011] In one embodiment, a guide rail groove is arranged inside each sliding block. A guide rail rod passes through and is slidably connected inside the guide rail groove. Telescopic arms are fixedly connected to both sides of the guide rail rod. A top shaft is embedded and rotatably connected to one side of the telescopic arm. A top bolt is arranged at the corresponding position of the top shaft. Through the action of the top bolt and the top shaft, the guide rail rod moves longitudinally to both sides.

[0012] In one embodiment, a telescopic device is arranged and slidably connected outside the top bolt. The top bolt can slide and displace inside the telescopic device, driving the telescopic arm and the guide rail rod to displace longitudinally. A fixed block is fixedly connected between the two telescopic devices. A fixed rod is fixedly connected between the telescopic device and the first guide rail plate. Through the action of the fixed rod, the telescopic device can be fixed on the first guide rail plate.

[0013] In one embodiment, a connecting block is fixedly connected below the sliding block. A connecting displacement block is fixedly connected below the connecting block. Rotating rods are respectively embedded and slidably connected to both sides inside the connecting displacement block. The rotating rods can displace in the connecting displacement block.

[0014] In one embodiment, a telescopic column is fixed and clamped between the two rotating rods. The telescopic column can be telescoped up and down to further open the gripper. A clamping jaw is fixedly connected below the telescopic column. The clamping jaw plays a role in grasping and releasing the object product.

[0015] Compared with the prior art, the mechanical gripper device of the present invention has the following advantages:

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] In Figures 1-4In the illustrated embodiment, the present invention provides a technical solution: a mechanical gripper device, including a substrate 18. On both sides of the top of the substrate 18, support plates 19 are respectively fixedly connected. Between the two support plates 19, a suspension plate 20 is fixedly connected. The suspension plate 20 is used to connect with the external ceiling to fixedly support the entire device. On the support plates 19, a number of stretching and fixing rivets 21 are provided. The stretching and fixing rivets 21 are used for the fixing of the device and can also play a role in stretching and supporting. On one side directly below the substrate 18, an anti-wear block 4 is fixedly connected. The anti-wear block 4 plays a role in preventing excessive friction and wear of the device. On both sides below the substrate 18, annular support rods 29 are respectively fixedly connected. Between the two annular support rods 29, a power rod 28 is rotatably connected. The power rod 28 provides the primary power for the entire device. Directly below the substrate 18, three first guide plates 25 are fixedly connected. The first guide plates 25 are arranged horizontally. Below the first guide plates 25, four second guide plates 22 are provided. The second guide plates 22 are arranged vertically.

[0027] In practical applications, compared with the existing mechanical gripper devices, a first track 8 is fixedly connected below each first guide plate 25. An attachment shaft 17 is embedded and slidably connected on the first track 8. The attachment shaft 17 is fixedly connected to the second guide plate 22. The attachment shaft 17 can drive the second guide plate 22 to slide on the first track 8, realizing the separation of the mechanical gripper in the horizontal and vertical directions. The second guide plate 22 is connected to the substrate 18 through the stretching and fixing rivets 21, which can play a role in supporting and stretching the second guide plate 22 during displacement. A second track 9 is fixedly connected below the second guide plate 22.

[0028] Furthermore, buffer fixing plates 30 are fixedly connected to both sides of the second guide plate 22. On the inner side of the buffer fixing plates 30, buffer rods 6 are fixedly connected. At the top of the buffer rods 6, buffer pads 7 are fixedly connected. The buffer pads 7 can prevent the gripper from spreading excessively and play a buffering role.

[0029] In Figures 1-4 the illustrated embodiment, a sliding block 13 is embedded and slidably connected below each second track 9. Between the two sliding blocks 13 at the central position, a connector 27 is elastically connected. Through the action of the connector 27, each sliding block 13 can be displaced in the horizontal and vertical directions.

[0030] In some embodiments, a guide rail groove 23 is provided inside each sliding block 13. A guide rail rod 24 passes through and is slidably connected inside the guide rail groove 23. Telescopic arms 2 are fixedly connected to both sides of the guide rail rod 24. A top shaft 16 is embedded and rotatably connected to one side of the telescopic arm 2. A top bolt 15 is provided at the corresponding position of the top shaft 16. Through the action of the top bolt 15 and the top shaft 16, the guide rail rod 24 moves longitudinally to both sides. A telescopic device 1 is provided outside and slidably connected to the top bolt 15. The top bolt 15 can slide and displace inside the telescopic device 1, driving the telescopic arm 2 and the guide rail rod 24 to move longitudinally. A fixed block 3 is fixedly connected between the two telescopic devices 1. A fixed rod 14 is fixedly connected between the telescopic device 1 and the first guide rail plate 25. Through the action of the fixed rod 14, the telescopic device 1 can be fixed on the first guide rail plate 25.

[0031] Further, a connecting block 12 is fixedly connected below the sliding block 13. A connecting displacement block 26 is fixedly connected below the connecting block 12. Rotating rods 11 are respectively embedded and slidably connected to both sides inside the connecting displacement block 26. The rotating rods 11 can displace inside the connecting displacement block 26. A telescopic column 10 is fixedly clamped between the two rotating rods 11. The telescopic column 10 can be telescoped up and down to further open the gripper. A clamping jaw 5 is fixedly connected below the telescopic column 10. The clamping jaw 5 functions to pick up and put down object products.

[0032] The specific working principle of the present invention will be elaborated in detail below: The entire device is fixed in a vertical position through a hanging plate 20. After being powered on, the power rod 28 rotates to provide the original power. First, the connecting shaft 17 moves horizontally on the first guide rail plate 25. Therefore, the second guide rail plate 22 separates horizontally under the action of the connecting shaft 17. Secondly, the top bolt 15 expands and contracts and displaces inside the telescopic device 1, acting on the top shaft 16 and the telescopic arm 2, driving the guide rail rod 24 to separate longitudinally. The sliding block 13 separates longitudinally on the second track 9. The above process realizes the horizontal transverse and longitudinal separation of the overall device. Finally, under the action of the rotating rod 11 and the connecting displacement block 26, the clamping jaw 5 can rotate and expand and contract up and down to simultaneously pick up and put down multiple products, with high picking efficiency.

[0033] In summary, a mechanical gripper device of the present invention can simultaneously realize the transverse and longitudinal separation of the gripper, and multiple grippers pick up and put down products, with high picking and placing efficiency.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
