Description

Technical Field

[0001] The utility model relates to the technical field of clamping equipment, and particularly relates to a variable-spacing jaw device. Background Art

[0002] In the fields of automated production and logistics handling, the end effector of a robot (such as a jaw device) is a key component for achieving precise grasping and handling. Traditional jaw devices are usually designed with a fixed spacing and can only grasp objects of specific sizes, which limits their adaptability in diverse production environments. Especially when grasping slender shaft-like workpieces, due to the varying lengths of the workpieces, the fixed-spacing jaws cannot meet the grasping requirements of workpieces of different lengths, resulting in reduced production efficiency and insufficient utilization of equipment. In addition, when it is necessary to grasp a basket or other non-shaft-like objects, the functional singularity of traditional jaws also restricts their application scope.

[0003] To solve the above problems, some adjustable-spacing jaw devices have been proposed in the prior art, but these devices often have complex structures, cumbersome adjustment processes, and cannot achieve multi-functional grasping. Therefore, it is necessary to design a new type of variable-spacing jaw device that can not only adapt to slender shaft-like workpieces of different lengths but also achieve the grasping of a basket through simple adjustment to improve the flexibility and working efficiency of automated equipment. Summary of the Utility Model

[0042] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0043] As Figure 1 and Figure 2 shown, a variable pitch jaw device 1 is installed on a manipulator 2 and is used to grasp a workpiece 3 or a basket 5, and includes:

[0044] At least two jaws; generally two jaws are provided. When the workpiece 3 is extra long or multiple workpieces 3 need to be clamped simultaneously, multiple jaws can also be provided;

[0045] The clamping mechanism 1-3, which is connected to the jaws and is used for clamping and opening the jaws;

[0046] The rotating mechanism 1-2, which is connected to the clamping mechanism 1-3 and is used for rotating the jaws to avoid obstacles or adapt to different grasping angles;

[0047] The telescopic mechanism 1-1, which is connected to the rotating mechanism 1-2 and is used for enabling the jaws to work at different strokes to grasp slender shaft-like workpieces 3 of different lengths;

[0048] The base 1-4, which is connected to the telescopic mechanism 1-1 or is connected to the telescopic mechanism 1-1 and the rotating mechanism 1-2.

[0049] In this embodiment, there are two jaws. When using the variable-spacing jaw device 1, through the telescoping of the telescopic mechanism 1-1, the two jaws are driven to move, changing the distance between the two jaws, and are used for enabling the jaws to work at different strokes of the telescopic mechanism 1-1 to grasp slender shaft-like workpieces 3 of different lengths. By providing the rotating mechanism 1-2, the jaws can be rotated by an angle to avoid obstacles or adapt to different grasping angles. For example, the variable-spacing jaw device 1 provided in this embodiment can grasp the workpiece 3 as Figure 2 shown, or the two jaws can be respectively rotated 90 degrees by the rotating mechanism 1-2 to grasp the handle 5-1 of the material basket 5 as Figure 5 and Figure 6 shown, improving the versatility of the jaws.

[0050] In one embodiment, the number of the telescopic mechanisms 1-1 is one, and the number of the rotating mechanisms 1-2 is two. One of the two rotating mechanisms 1-2 is connected to the telescopic mechanism 1-1, and the other is connected to the base 1-4. That is, only the action of one telescopic mechanism 1-1 changes the distance between the two jaws, and one of the jaws is fixed in position, and the other jaw moves under the drive of the telescopic mechanism 1-1.

[0051] In one embodiment, the number of the telescopic mechanisms 1-1 is two, and the number of the rotating mechanisms 1-2 is two. The two rotating mechanisms 1-2 are respectively connected to the two telescopic mechanisms 1-1. That is, the action of the two telescopic mechanisms 1-1 changes the distance between the two jaws. Of course, when executing, either only the action of one telescopic mechanism 1-1 can be controlled to change the distance between the two jaws, or the actions of the two telescopic mechanisms 1-1 can be controlled to act simultaneously to change the distance between the two jaws. The advantage of the two telescopic mechanisms 1-1 acting simultaneously is that the action speed of adjusting the distance between the jaws is faster.

[0052] In one embodiment, as Figure 3As shown, the two telescopic mechanisms 1-1 are centrally symmetrically arranged on the base 1-4. Such an arrangement not only allows the two telescopic mechanisms 1-1 to act simultaneously, thereby making the action speed of adjusting the jaw spacing faster, but also enables better centering.

[0053] In one embodiment, Figure 4 As shown, the telescopic mechanism 1-1 includes a telescopic cylinder, a cylinder mounting seat 1-1-1 and a slider 1-1-2, the telescopic cylinder connects the cylinder mounting seat 1-1-1 and the slider 1-1-2, the cylinder mounting seat 1-1-1 is connected to the base 1-4, the slider 1-1-2 is slidably connected to the base 1-4, and the slider 1-1-2 is connected to the rotating mechanism 1-2.

[0054] In one embodiment, the driving device of the rotating mechanism 1 - 2 is a rotating cylinder.

[0055] In one embodiment, the driving device of the clamping mechanism 1 - 3 is a clamping cylinder.

[0056] In other embodiments, the driving devices of the telescopic mechanism 1 - 1 , the rotating mechanism 1 - 2 and the clamping mechanism 1 - 3 described above may also be electric devices.

[0057] In one embodiment, the clamp comprises a first clamp 1-3-1 and a second clamp 1-3-2, and the first clamp 1-3-1 is provided with a yield structure. Figure 5 and Figure 6 As shown, since a supporting partition is provided on the storage rack 4 storing the workpieces 3 in the material basket 5, the clamping claws can be prevented from touching the supporting partition by providing the yield structure.

[0058] In one embodiment, a flexible material layer is provided on the clamping surface of the clamping jaws, which can protect the surface of the workpiece and avoid damage during the clamping process, and can also avoid noise during the clamping process.

[0059] In one embodiment, the flexible material layer is made of rubber.

[0060] To sum up, the technical solution of the present application, through innovative structural design and the setting of clamping mechanism, rotating mechanism and telescopic mechanism, can not only adapt to the clamping of slender shaft workpieces 3 of different lengths, but also realize the grasping of the material basket 5 through simple adjustment. It not only meets the requirements of modern automated production for the versatility and adaptability of the clamping device, but also improves production efficiency and reduces costs, and has good market application prospects.
