Description

Technical Field

[0001] This application relates to the technical field of jigs, and particularly to a jig for machining electrode rods. Background Art

[0002] The electrode rod mainly consists of three parts: the electrode head, the rod part, and the tail part. The electrode head is the part that contacts the welded part for welding. The rod part is the basis of the electrode, usually referring to the diameter of the electrode body, that is, the rod diameter, which is the basic dimension of the electrode, and its length depends on the requirements of the welding process. The tail part is the contact part where the electrode cooperates with the holding rod or the electrode arm, and certain machining accuracy is required to ensure the smooth transmission of welding current and electrode force.

[0003] When machining the electrode rod, it needs to be clamped and fixed. Usually, a three-jaw chuck is used for clamping. A plurality of clamping blocks are slidably mounted on the three-jaw chuck. One end of the electrode rod is inserted between the plurality of clamping blocks, and the plurality of clamping blocks are driven to move synchronously towards the center of the three-jaw chuck, so that the plurality of clamping blocks can jointly clamp one end of the electrode rod, and the electrode rod is connected and fixed to the three-jaw chuck, facilitating the subsequent machining operation of the electrode rod.

[0004] However, in this type of clamping method for the electrode rod, when the length of the electrode rod to be clamped is relatively long, after the three-jaw chuck clamps and fixes one end of the electrode rod, there is a relatively large distance between the other end of the electrode rod and the clamping blocks of the three-jaw chuck. As a result, when machining the electrode rod subsequently, the end of the electrode rod far from the three-jaw chuck is prone to shaking, reducing the machining accuracy of the electrode rod. Therefore, further improvement is needed. Summary of the Utility Model

[0047] Embodiment 3:

[0048] This application embodiment discloses an electrode rod processing fixture.

[0049] Refer to Figure 5 、 Figure 6 The difference between the electrode rod processing fixture disclosed in this application embodiment and Embodiment 2 is as follows:

[0050] An installation cavity 213 is formed in the first extension part 21, and a sliding groove 211 is formed in the side wall of the first extension part 21 close to the second extension part 22. The sliding groove 211 communicates with the installation cavity 213. In this embodiment, the adjusting assembly 4 includes a sliding rod 41, a limiting block 43, a spring 44 and an unlocking member. One end of the sliding rod 41 is connected to the second extension part 22, and the other end slidably passes through the sliding groove 211 and extends into the installation cavity 213. A plurality of limiting ring grooves 412 are formed in the peripheral wall of the sliding rod 41, and the plurality of limiting ring grooves 412 are arranged at intervals along the axial direction of the sliding rod 41.

[0051] Refer to Figure 6, Two sliding frames 216 are slidably installed in the installation cavity 213. The two sliding frames 216 are respectively slidably installed on two opposite inner walls of the installation cavity 213. In this embodiment, there are two limiting blocks 43. The two limiting blocks 43 are arranged corresponding to the two sliding frames 216. The limiting blocks 43 are installed on the corresponding sliding frames 216. Each limiting block 43 is slidably installed in the installation cavity 213 through the corresponding sliding frame 216.

[0052] The number of the springs 44 is set corresponding to the number of the limiting blocks 43 (that is, the number of the springs 44 is set corresponding to the number of the sliding frames 216). One end of each spring 44 is fixedly connected to the sliding frame 216 of the corresponding limiting block 43, and the other end is fixedly connected to the inner wall of the installation cavity 213. The springs 44 normally force the corresponding limiting blocks 43 to be clamped in the limiting ring groove 412. Each limiting block 43 is clamped in the limiting ring groove 412 through the corresponding spring 44.
