Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and more specifically, it relates to a fixture for grinding the shell of a robotic arm. Background Technology

[0002] The robotic arm's outer shell has a certain degree of curvature, resulting in an outward-curving outer surface and an inward-curving inner surface. Both are exposed and therefore require grinding after machining to achieve the desired surface roughness. However, because the grinding locations on the outer and inner surfaces differ, specialized fixtures for different positions are needed for clamping and positioning; otherwise, operation is difficult. Therefore, this invention proposes a fixture for grinding the robotic arm's outer shell. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a jig for grinding the shell of a robotic arm. This jig has the characteristics of multi-directional clamping and grinding without blind spots.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The present utility model relates to a jig for grinding the shell of a robotic arm, including an upper jig and a lower jig. The upper jig includes an upper top plate, and the bottom of the upper top plate is provided with a first pneumatic gripper near one end with the gripper head facing downward and an upper positioning groove near the other end with the slot facing downward. The upper top plate is also provided with an upper lever clamping cylinder, and the lever clamping arm of the upper lever clamping cylinder is located on one side of the upper positioning groove. The lower jig includes a lower bottom plate, and the top of the lower bottom plate is provided with a second pneumatic gripper near one end with the gripper head facing upward and a pad near the other end. The pad has a lower positioning groove with the slot facing upward. The pad is also provided with a lower lever clamping cylinder, and the lever clamping arm of the lower lever clamping cylinder is located on one side of the lower positioning groove.

[0005] The present invention is further configured such that the first pneumatic gripper is positioned directly above the second pneumatic gripper.

[0006] The present invention is further configured such that: both the first pneumatic gripper and the second pneumatic gripper are inward-opening pneumatic grippers.

[0007] In summary, the present invention has the following beneficial effects: The jig for grinding the outer shell of the robotic arm involved in the present invention can be used alone to clamp and position the inwardly bent robotic arm shell for grinding the outer surface of the shell; and can be used alone to clamp and position the outwardly bent robotic arm shell for grinding the inner surface of the shell, thereby achieving multi-directional clamping and grinding without blind spots. The overall function is complete and highly practical. Attached Figure Description

[0012] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0013] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0014] Example 1

[0015] See Figures 1 to 4 As shown, the jig for grinding the shell of a robotic arm involved in this embodiment includes an upper jig 100 and a lower jig 200.

[0016] The upper clamp 100 includes an upper top plate 101. The bottom of the upper top plate 101 is provided with a first pneumatic gripper 102 near one end with the gripper facing downward and an upper positioning groove 103 near the other end with the slot facing downward. The upper top plate 101 is also provided with an upper lever clamping cylinder 104. The lever clamping arm on the upper lever clamping cylinder 104 is located on one side of the upper positioning groove 103.

[0017] The lower clamp 200 includes a lower base plate 201. The top of the lower base plate 201 is provided with a second pneumatic gripper 202 near one end with the gripper facing upward and a pad block 203 near the other end. The pad block 203 is provided with a lower positioning groove 204 with the slot facing upward. The pad block 203 is also provided with a lower lever clamping cylinder 205. The lever clamping arm on the lower lever clamping cylinder 205 is located on one side of the lower positioning groove 204.

[0018] Furthermore, the first pneumatic gripper 102 is positioned directly above the second pneumatic gripper 202.

[0019] Furthermore, both the first pneumatic gripper 102 and the second pneumatic gripper 202 are inward-opening pneumatic grippers.

[0020] In this embodiment, when grinding the outwardly bent portion of the robotic arm housing, the upper clamp 100 is used to clamp and position the workpiece. The clamping method is as follows: the first pneumatic gripper 102 is used in an inward-opening manner, with the gripper head inserted into the hole in the robotic arm housing for fixation. The portion of the robotic arm housing away from the hole is supported in the upper positioning groove 103 and fixed by the upper lever clamping cylinder 104 for tightening. When grinding the inwardly bent portion of the robotic arm housing, the lower clamp 200 is used to clamp and position the workpiece. The clamping method is as follows: the second pneumatic gripper 202 is used in an inward-opening manner, with the gripper head inserted into the hole in the robotic arm housing for fixation. The portion of the robotic arm housing away from the hole is supported in the lower positioning groove 204 and fixed by the lower lever clamping cylinder 205 for tightening.

[0021] The pad 203 is used as a pad and for raising.

[0022] The present invention relates to a jig for grinding the outer shell of a robotic arm. The upper jig is used alone to clamp and position the inwardly bent outer shell of the robotic arm for grinding the outer surface of the shell; the lower jig is used alone to clamp and position the outwardly bent outer shell of the robotic arm for grinding the inner surface of the shell. This achieves multi-directional clamping and grinding without blind spots. The overall function is complete and highly practical.
