Description

Technical Field

[0001] The utility model belongs to the technical field of conductor testing tooling, in particular to a clamping device for conductor testing. Background Art

[0002] A conductor is a material with very low resistivity and can easily conduct electric current. There are a large number of freely movable charged particles in a conductor, called carriers. Under the action of an external electric field, the carriers move in a directional manner to form an obvious current. Metals are the most common type of conductor. In order to ensure the performance of conductors, they will be tested.

[0003] The existing public patent (publication number CN 220575716 U) discloses a clamping device for conductor testing, which solves the problem that the conductor is not convenient to clamp quickly during the test, which affects the operation of the staff and is not convenient for better testing operations. The device comprises a supporting shell, and a clamping assembly is symmetrically fixedly installed on the top of the supporting shell. An adjusting mechanism is installed inside the supporting shell, and the top of the adjusting mechanism extends to the top of the supporting shell and is connected to the clamping assembly. The adjusting mechanism comprises an adjusting motor, and the adjusting motor is fixedly installed at the middle of the inner top of the supporting shell. A threaded rod is fixedly installed on the output shaft of the adjusting motor, and the bottom of the threaded rod is rotatably connected to the middle of the inner bottom end of the supporting shell. The utility model can make the conductor convenient to clamp quickly during the test, so that the staff can better operate and thus facilitate better testing operations.

[0004] The structure of the above-mentioned clamping device is relatively complicated, occupies a large space, and the linkage between its various structures is poor. Therefore, we provide a conductor test clamping device to solve the above-mentioned problems. Utility Model Content

[0007] The utility model is further configured that a circular notch for the conductor to pass through is opened in the middle of the bottom plate, and an end plate is fixed to the end of the bottom plate, and a mounting hole is arranged at the corner of the end plate.

[0008] The utility model is further configured such that the cylinder base is fixed to the middle position of the inner side of the end plate, and the piston end of the cylinder is fixed to the middle position of the side of the support arm.

[0009] The utility model is further configured that a guide rod is passed through the interior of the buffer, one end of the guide rod is passed through the middle position of the end plate, and the other end of the guide rod is fixed to the middle position of the two side surfaces of the support arm.

[0010] The utility model is further configured that the first transmission arm and the second transmission arm end portions are movably connected relative to the bottom plate via the second shaft member.

[0011] The utility model is further configured that the insulating member is an arc-shaped structure, and the insulating member is clamped and fixed on the outside of the cylindrical conductor.

[0012] The utility model has the following beneficial effects:

[0013] The utility model clamps and fixes the conductor to be tested by setting a clamping assembly, and its composition structure is simple, with a four-link structure composed of a support arm 1, a support arm 2, a transmission arm 1, and a transmission arm 2, a cylinder as a driving structure, and a buffering method of a buffer part, and an insulating part to stably clamp the conductor. At the same time, its structural changes can meet the clamping requirements of conductors of different sizes;

[0014] Specifically, when the cylinder is started, the piston end of the cylinder drives the telescopic movement of arm one. When arm one moves, it will drive the rotation of transmission arm one that cooperates with its end. At the same time, transmission arm two is pulled by transmission arm one, driving arm two to move linearly. In this process, the buffer elastically deforms to achieve clamping buffering, and at the same time, the guide rod moves relative to the end plate to balance the movement of arm two.

[0025] Specifically, in the conductor testing clamping device proposed in the present application, a clamping assembly is provided to clamp and fix the conductor to be tested. Its composition structure is simple, with a four-bar structure consisting of a support arm 3, a support arm 2 10, a transmission arm 1 4, and a transmission arm 2 6. The cylinder 5 is used as a driving structure, and the buffering method of the buffer part 11 is cooperated with the insulating part 7 to stably clamp the conductor. At the same time, its structure changes to meet the clamping requirements of conductors of different sizes.

When the support arm 3 moves, it will drive the rotation of the transmission arm 4 matched with its end. At the same time, the transmission arm 2 6 is pulled by the transmission arm 4 to drive the linear movement of the support arm 2 10. In this process, the elasticity of the buffer 11 changes to achieve clamping buffering.
