[0002] At present, many manipulators are used in the automated production lines of factories. Various types of jaws are required for different manipulators, and such jaws can be used for various tasks such as grasping different objects.

[0003] In the automated processing pipeline of automobiles, products are often grabbed from a tray to a positioning table by a four-axis robot jaw and fixed by the jaw set on the positioning table. However, the jaw set on the positioning table does not have a function of adjusting the spacing. In the subsequent processing of the pipeline, it is also necessary to moderately adjust the distance between products to facilitate subsequent processing. Jaws that are difficult to adjust cannot meet the requirements of subsequent processing and are not convenient for users to use. Content of the Utility Model

[0023] Please refer to Figures 1-4

[0024] Embodiment 1: A variable pitch gripper, comprising a mounting connecting plate 1, two side baffles 2 symmetrically arranged on both sides of the mounting connecting plate 1, two limit sliding rails 3 symmetrically arranged at the top of the mounting connecting plate 1, and a moving connecting plate 4 arranged above the mounting connecting plate 1.

[0025] Two limit sliding blocks 5 are symmetrically arranged on both sides of the bottom end of the moving connecting plate 4. The limit sliding blocks 5 are slidably clamped on the limit sliding rails 3. A side connecting frame 6 is arranged at the top end of the moving connecting plate 4. A bottom connecting plate 7 is arranged at the top end of the moving connecting plate 4. A first clamping driving cylinder 8 is installed on the bottom connecting plate 7. Two product clamping plates 9 are symmetrically arranged on the driving end of the first clamping driving cylinder 8.

[0026] Two first side connecting rods 10 are symmetrically arranged on both sides of the bottom connecting plate 7. A first supporting contact block 11 is arranged at the end of the first side connecting rod 10. A first product main body 12 is arranged on the side of the product clamping plate 9. A cylinder connecting frame 13 is arranged at the bottom of the mounting connecting plate 1. An adjusting driving cylinder 14 is installed on the cylinder connecting frame 13. A driving pull rod 15 is arranged at the driving end of the adjusting driving cylinder 14. A pulling block 16 is arranged at the end of the driving pull rod 15. A pulling connecting plate 17 is limit clamped on the pulling block 16.

[0027] The top end of the pulling connecting plate 17 is connected to the bottom end of the moving connecting plate 4. A side mounting plate 18 is connected to the side of the mounting connecting plate 1. A second clamping driving cylinder 19 is installed on the side mounting plate 18. Two product contact plates 20 are symmetrically arranged on the driving of the second clamping driving cylinder 19. Two second side connecting rods 21 are symmetrically arranged on both sides of the second clamping driving cylinder 19. A second supporting contact block 22 is arranged at the end of the second side connecting rod 21. A second product main body 23 is arranged on the side of the product contact plate 20.

[0028] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the side mounting plate 18 and the upper end surface of the moving connecting plate 4 are located on the same horizontal plane.

[0029] So that the second clamping driving cylinder 19 and the first clamping driving cylinder 8 can be located on the same horizontal plane.

[0030] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the driving ends of the first clamping driving cylinder 8 and the product contact plate 20 can move closer to or away from each other.

[0031] So that the two product clamping plates 9 and the product contact plate 20 symmetrically arranged on the driving end of the first clamping driving cylinder 8 can move closer to each other, thereby clamping the sides of the second product main body 23 and the first product main body 12 more stably.

[0032] Embodiment 4: The difference between this embodiment and Embodiment 1 is that both the second supporting abutting block 22 and the first supporting abutting block 11 are L-shaped.

[0033] This makes the clamping of the sides of the first product body 12 and the second product body 23 by the second supporting abutting block 22 and the first supporting abutting block 11 more stable.

[0034] In this embodiment, in an automotive automated processing assembly line, products are often grabbed from a pallet to a positioning table by a four-axis robot gripper and fixed by the grippers provided on the positioning table. However, the grippers provided on the positioning table do not have a function of adjusting the spacing. In subsequent processing on the assembly line, it is also necessary to moderately adjust the distance between products to facilitate subsequent processing. The grippers that are difficult to adjust cannot meet the requirements of subsequent processing and are not convenient for users to use.

[0035] In summary, during specific implementation, when the products on the automotive assembly line are clamped and transferred by the robot to the first supporting abutting block 11 at the end of the first side connecting rod 10, the two first supporting abutting blocks 11 can support the first product body 12, and the end of the first product body 12 is inserted between the two product clamping plates 9. The user starts the first clamping driving cylinder 8, so that the first clamping driving cylinder 8 drives the two product clamping plates 9 to clamp and fix the end of the first product body 12, thereby stably fixing the transferred first product body 12.

[0036] Subsequently, the transferred second product body 23 is also supported by the two second supporting abutting blocks 22. After the second clamping driving cylinder 19 is started, it drives the two product abutting plates 20 to clamp and fix the end of the second product body 23, so that the second product body 23 is also stably fixed at the end of the second clamping driving cylinder 19. At this time, the user can start the adjusting driving cylinder 14 provided at the bottom of the mounting connecting plate 1. The adjusting driving cylinder 14 pulls the driving pull rod 15. The end of the driving pull rod 15 is provided with a pulling block 16. The pulling block 16 is provided with a pulling connecting plate 17. The top end of the pulling connecting plate 17 is connected to the bottom end of the moving connecting plate 4.

[0037] On both sides of the bottom end of the moving connecting plate 4, two limiting sliders 5 are symmetrically arranged. The limiting sliders 5 are slidably clamped on the limiting sliding rails 3. Thus, the adjusting driving cylinder 14 can drive the first clamping driving cylinder 8 installed on the moving connecting plate 4 through the driving pull rod 15, and at the same time drive the first product body 12 clamped on the product clamping plate 9 arranged at the end of the first clamping driving cylinder 8 to move towards the side of the second product body 23 arranged at the end of the second clamping driving cylinder 19, so that the distance between the first product body 12 and the second product body 23 can be adjusted controllably. Furthermore, it is convenient for the subsequent robot to transfer and process the product again, meeting the processing requirements of users and being more convenient for users to use.
