Technical Field
[0001] This invention relates to the technical field of material gripping, and more specifically, to a multifunctional composite gripper. Background Technology
[0002] In the field of mechanical manufacturing, in order to realize the loading and unloading of materials, most of the time it is necessary to use grippers to grab the materials and then drive the materials to carry out loading and unloading operations.
[0003] In actual production, when loading workpieces, most workpieces are placed in material frames, and then multiple material frames are stacked together. When using them, the workpieces in the topmost material frame are picked up first. After all the workpieces in the topmost material frame have been picked up, the topmost material frame is picked up, and then the workpieces in the next material frame are picked up.
[0004] However, different grippers are needed to grip workpieces and material frames. In the existing technology, this is mostly achieved through two solutions. One is to design a gripper that can grip multiple workpieces, which increases the cost of the gripper. The other is to design two sets of grippers and then use quick-change connectors to disassemble and install the grippers. The disadvantage of this solution is that it takes a lot of time to replace the grippers, which reduces the feeding efficiency. Summary of the Invention

[0015] The present invention is further configured such that a patch is detachably connected to the side of the clamping claw away from the axis of the fixing part.
[0016] The present invention is further configured such that: the connector is configured as a cylindrical tube, and the plurality of clamping claws of the first clamping assembly can extend into the connector to tighten the connector.
[0017] The present invention is further configured such that: there are two connectors and two corresponding first clamping components.
[0018] The present invention is further configured such that: the second clamping component includes two sliding claws disposed at the bottom of the second body, the two sliding claws are slidably connected to the second body in a horizontal direction, and the two sliding claws slide in the same straight line direction to achieve the two sliding claws moving closer and further apart.
[0019] The invention is further configured such that at least two protrusions are fixedly connected to the sides of the two sliding claws that are far apart from each other.
[0020] The present invention is further configured such that: a camera for acquiring the coordinate position and angular orientation of the workpiece is provided on the first main body.

Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.
[0030] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0031] Example: A multifunctional composite gripper, see attached document. Figure 1 -Appendix Figure 5 The device includes a first gripping mechanism 1 and a second gripping mechanism 2. The first gripping mechanism 1 is used to grip a workpiece; the second gripping mechanism 2 is used to grip a material frame. The second gripping mechanism 2 includes a second body 21, a connecting member 23, and a second clamping assembly 22. The connecting member 23 has the same structural shape as the workpiece and is fixedly connected to the top of the second body 21 and can be gripped by the first gripping mechanism 1. The second clamping assembly 22 is used to clamp the material frame and is located at the bottom of the second body 21.
[0032] In operation, when clamping a workpiece, the first gripping mechanism 1 grips it directly. When gripping a material frame, the first gripping mechanism 1 grips the connecting piece 23 on the second gripping mechanism 2, thus achieving gripping of the second gripping mechanism 2 by the first gripping mechanism 1. Then, the second gripping mechanism 2 directly grips the material frame. After gripping the material frame, the first gripping mechanism 1 releases its grip on the second gripping mechanism 2, and the first gripping mechanism 1 can then grip the workpiece again.
[0033] Specifically, the workpiece is cylindrical, and the first gripping mechanism 1 includes a first main body 12 and a first clamping assembly 11; the first clamping assembly 11 is used to clamp the workpiece by supporting it on the inner wall of the workpiece.
[0034] Specifically, the first clamping assembly 11 includes a fixing part 111 and clamping claws 112. The fixing part 111 is fixedly connected to the bottom of the first main body 12, and the fixing part 111 is configured as a cylinder with a vertical axis. Three clamping claws 112 are provided, which are located at the bottom of the fixing part 111 and evenly arranged around the axis of the fixing part 111. The clamping claws 112 slide along the radial direction of the fixing part 111 at the bottom of the fixing part 111. The sliding of the clamping claws 112 on the fixing part 111 is driven by a cylinder.
[0035] Specifically, a patch 113 is detachably connected to the side of the clamping jaw 112 away from the axis of the fixing part 111. By setting the patch 113, it is possible to select whether to connect the patch 113 to the clamping jaw 112 according to the size of the inner diameter of the workpiece, so that the clamping jaw 112 can clamp workpieces of more sizes.
[0036] Specifically, the connector 23 is configured as a cylindrical tube, and the multiple clamping claws 112 of the first clamping assembly 11 can extend into the connector 23 to tighten the connector 23.
[0037] Specifically, there are two connectors 23, and there are correspondingly two first clamping components 11.
[0038] By setting two connectors 23 and two first clamping components 11, when the first gripping mechanism 1 grips the second gripping mechanism 2, the two connectors 23 can be tightened by the two first clamping components 11 respectively, so as to achieve a stable gripping of the second gripping mechanism 2 by the first gripping mechanism 1.
[0039] Specifically, the second clamping assembly 22 includes two sliding claws 221, which are disposed at the bottom of the second body 21. The two sliding claws 221 are slidably connected to the second body 21 in a horizontal direction, and slide along the same straight line to bring the two sliding claws 221 closer together and further apart. The sliding of the sliding claws 221 on the second body 21 is driven by a cylinder.
[0040] The material frame is gripped by two sliding claws 221 that hold it firmly inside the frame.
[0041] Specifically, each of the two sliding claws 221 has at least two protrusions fixedly connected to the side of each other that is far apart from each other.
[0042] Specifically, the first body 12 is equipped with a camera for acquiring the coordinate position and angular orientation of the workpiece.
[0043] Specifically, the first main body 12 is equipped with a laser rangefinder for confirming the height of workpiece gripping and placement.
