The second sliding bar is also provided with a second plane on the same side as the second rack portion, and the first sliding bar is also provided with a first plane on the same side as the first rack portion. The first and second sliding bars are slidably connected by the first plane and the second plane abutting against each other.

[0008] Furthermore, the second slide bar is located below the first slide bar, the first claw toe and the second claw toe are symmetrical, and the second claw toe is located between the first claw toe and the mounting base.

[0009] Furthermore, the mounting base includes a base body, several bearing seats fixedly mounted on the base body, and a fixing plate fixedly mounted on the side of the base body near the cylinder. The first slide bar and the second slide bar are slidably connected to the base body, and the ball bearing is mounted on the bearing seat.

[0010] Furthermore, an elastic guide is provided between the fixed plate and the second slide bar. The elastic guide includes a guide post and a spring sleeved on the guide post.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 , Figure 2 and Figure 3As shown, the multi-claw gripping device provided in the embodiment of this application includes a mounting base 1, a cylinder 2 fixedly mounted on one side of the mounting base 1 along the Y direction, a connecting plate 3 fixedly mounted on the output end of the cylinder 2, and a plurality of gripping components 4 arranged along the Y direction on the mounting base 1. The gripping components 4 include a first slide bar 41 fixedly connected to the connecting plate 3 and slidably connected to the mounting base 1, a second slide bar 42 slidably connected to the mounting base 1, a ball bearing 43 mounted on the mounting base 1, a rotating shaft 44 fixedly connected to the inner ring of the ball bearing 43, and a gear 45 coaxially fixedly connected to the rotating shaft 44. The first slide bar 41 is provided with a first rack portion 411 meshing with the gear 45, and the second slide bar 42 is provided with a second rack portion 421 meshing with the gear 45. A first claw toe 46 is fixedly mounted on the end of the first slide bar 41 away from the connecting plate 3, and a second claw toe 47 is fixedly mounted on the end of the second slide bar 42 away from the connecting plate 3.

[0018] In actual use, when it is necessary to clamp the product, the cylinder 2 drives the connecting plate 3 to move the first slide bar 41 towards the cylinder 2. Due to the meshing of the first rack part 411 with the gear 45, and the meshing of the gear 45 with the second rack part 421, the gear 45 drives the second rack part 421 to move away from the cylinder 2, so that the first claw toe 46 and the second claw toe 47 move towards each other to complete the clamping action.

[0019] In the above design, the cylinder 2 drives the connecting plate 3 to move, which in turn drives multiple clamping components 4 to move, effectively enabling batch clamping of products, saving costs and improving work efficiency.

[0020] Specifically: such as Figure 3 and Figure 2 As shown, the mounting base 1 is provided with a sliding groove 101 extending along the Y direction. The first slide bar 41 and the second slide bar 42 are both slidably connected to the sliding groove 101. The second slide bar 42 is also provided with a second plane on the same side as the second rack part 421. The first slide bar 41 is also provided with a first plane on the same side as the first rack part 411. The first slide bar 41 and the second slide bar 42 are slidably connected by the first plane and the second plane abutting against each other.

[0021] In actual use, when the first slide bar 41 is driven by the connecting plate 3 to move synchronously, the first slide bar 41 slides in the slide groove 101. When the second slide bar 42 is driven by the gear 45, the second slide bar 42 also slides in the slide groove 101. During the sliding process, the first plane and the second plane slide against each other.

[0022] In the above design, the structural design and specific implementation of the mounting base 1, the first slider 41 and the second slider 42 can effectively achieve the stability of the first slider 41 and the second slider 42 during the sliding process.

[0023] Specifically: such as Figure 2 and Figure 3 As shown, the second slide bar 42 is located below the first slide bar 41, the first claw toe 46 and the second claw toe 47 are symmetrical, and the second claw toe 47 is located between the first claw toe 46 and the mounting base 1.

[0024] In the above design, the second slide bar 42 is placed below the first slide bar 41, so that the first slide bar 41 and the second slide bar 42 have corresponding parts in the vertical direction, and the first claw toe 46 and the second claw toe 47 are arranged along the Y direction. Compared with the arrangement of the first claw toe 46 and the second claw toe 47 along the X direction, it can save more space and install more clamping components 4.

[0025] Specifically: such as Figure 3 As shown, the mounting base 1 includes a base body 11, a plurality of bearing seats 13 fixedly mounted on the base body 11, and a fixing plate 12 fixedly mounted on the side of the base body 11 near the cylinder 2. The first slide bar 41 and the second slide bar 42 are slidably connected to the base body 11, and the ball bearing 43 is mounted on the bearing seat 13.

[0026] Specifically: such as Figure 2 and Figure 3 As shown, an elastic guide 5 is also provided between the fixed plate 12 and the second slide bar 42. The elastic guide 5 includes a guide post 51 and a spring 52 sleeved on the guide post 51. The fixed plate 12 is provided with a through hole 120 that is slidably connected to one end of the guide post 51. The other end of the guide post 51 is fixed to the end of the second slide bar 42. The two ends of the spring 52 abut against the second slide bar 42 and the fixed plate 12, respectively.

[0027] In actual use, when the second slide bar 42 moves toward the fixed plate 12, the guide post 51 is slidably connected to the fixed plate 12 through the through hole 120, compressing the spring 52.

[0028] In the above design, the structural design and specific implementation of the elastic guide 5 can buffer the sliding of the second slide bar 42. Since both the second slide bar 42 and the first slide bar 41 are engaged with the gear 45, and the sliding power of the second slide bar 42 and the first slide bar 41 comes from the cylinder 2, the elastic guide 5 can provide buffering force to prevent the first slide bar 41 and the second slide bar 42 from moving too fast, so that the first claw toe 46 and the second claw toe 47 will cause excessive impact when clamping the product.

[0029] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
