Description

Technical Field

[0001] The utility model relates to the technical field of clamping jaws, in particular to a double-row clamping jaw. Background Art

[0002] With the development of science and technology, the tools people use at work are becoming more and more technologically advanced. For example, many factory workshops are now equipped with grippers. Grippers are a very common and necessary device in the field of robotics and are widely used in production.

[0003] For example, a chuck with multiple rows of jaws, whose application number is CN202120330232.9 and whose authorization announcement date is 20211119, includes a chuck, an elastic diaphragm and jaws. The chuck is fixedly connected to the grinder and is driven to rotate by the grinder spindle. An elastic diaphragm is fixed on one side of the chuck and a push rod is provided on the other side, and the push rod can pass through the chuck and contact the elastic diaphragm. At least four arc-shaped jaws are evenly distributed and fixed in the direction of the same circumference of the elastic diaphragm, and at least two jaw bolts are fixed in the axial direction of each jaw. Multiple rows of jaw bolts are used, that is, the first jaw bolt is set as the first row of jaw bolts, and the second jaw bolt is set as the second row of jaw bolts. The first row of jaw bolts and the second row of jaw bolts respectively determine the axis of a workpiece, and the position of the workpiece is determined by the two axis centers, so that the verticality between the end face of the workpiece and the outer wall of the workpiece will not affect the rotation of the workpiece, that is, there will be no rotational jump.

[0004] Current grippers usually use pneumatic grippers directly for clamping, but for parts with irregular shapes, pneumatic grippers are inconvenient to clamp, and the number of grippers that can be clamped each time is limited. In addition, the accuracy of product clamping is not precise enough, and the efficiency of clamping products is low, which affects the production efficiency of the products. Therefore, it is urgent to design a double-row gripper to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a double-row clamping jaw to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A double-row clamp comprises a mounting frame, wherein a plurality of clamp assemblies are mounted on the outer wall of one side of the mounting frame by bolts, and the clamp assembly comprises a steering gear, which is mounted on the outer wall of one side of the mounting frame by bolts, the output end of the steering gear is mounted with a pneumatic clamp by bolts, and the outer walls on both sides of the pneumatic clamp are mounted with connecting frames by bolts, the bottom ends of the two connecting frames are mounted with frames by bolts, and the outer walls on both sides of the top of the frame are threadedly connected with contacts, and the outer walls on both sides of the bottom of the frame are mounted with connecting plates by bolts, and the two output ends of the pneumatic clamp are mounted with sliding claws by bolts, and the bottom end of one of the sliding claws is mounted with clamping block one by bolts, and the bottom end of the other sliding claw is mounted with clamping block two by bolts.

[0008] Furthermore, adapter boxes are installed on both sides of the outer wall of the top of the mounting frame by bolts, and a connecting valve is provided inside the adapter box.

[0009] Furthermore, a plurality of connecting valve heads are threadedly connected to the outer wall of one side of the pneumatic clamp, and the connecting valve heads are communicated with the connecting valves through pipelines.

[0010] Furthermore, a connecting flange is installed at the center of the top of the mounting frame through bolts, and a plurality of through holes are opened on the outer wall of the top of the connecting flange.

[0011] In the above technical solution, the double-row clamping jaws provided by the present invention have the following beneficial effects:

[0012] (1) The clamping claw assembly designed in the present invention can restrict both sides of the product when the clamping claw assembly clamps the product, and locate the product position, so that the sliding claw can accurately grasp the product. At the same time, the clamping of the two sliding claws can improve the firmness of the clamping assembly on the product. In addition, the design of the clamping block 1 and the clamping block 2 can enable the sliding claw to clamp products with irregular shapes.

[0013] (2) The contact designed in the present invention is a sensing element. When the clamping assembly descends to clamp the product, the contact will first contact the product, and then the pneumatic clamp will be activated, which can prevent the clamping assembly from descending a long distance and crushing the product.
