Description

Technical Field

[0001] The utility model relates to the field of resistance welding, in particular to a resistance welding electrode mounting structure and a quick installation and verification jig. Background Technique

[0002] Resistance welding refers to a method of locally heating the workpiece by using the resistance heat generated when the current passes through the workpiece and the contact area, and at the same time applying pressure for welding. During welding, no filler metal is required, the productivity is high, the deformation of the workpiece is small, and it is easy to realize automation.

[0003] Resistance welding uses the resistance heat effect generated by the current flowing through the contact surface and adjacent areas of the workpiece to heat it to the melting or plastic state, so as to form a metal bond. There are mainly four resistance welding methods, namely spot welding, seam welding, projection welding, and butt welding.

[0004] Among them, electric welding assembles the workpieces into a lap joint and presses them tightly between two columnar electrodes, and uses the resistance heat to melt the base metal. During the welding process, the two electrodes will wear, resulting in the shortening of the two electrode columns. Therefore, after the welding work is used for a period of time, it is necessary to verify the position of the electrodes to keep the electrodes at their original length.

[0005] The existing verification method uses manual verification. In this verification method, it is not easy to control the adjusted length of the electrodes by visual observation, and it is easy to have the situation that the electrodes are adjusted too short or too long, which is not conducive to the subsequent welding treatment of the products. Content of the Utility Model

[0007] The utility model provides the following technical solutions;

[0008] A resistance welding electrode mounting structure and a quick installation and verification jig, including a base and an electrode mounted on the base. One corner of the base fits with an assembly block, and assembly grooves that are mutually adapted are opened at one corner where the base contacts the assembly block for assembling the electrode. A connecting block is detachably mounted on another side of the base, and one end of the connecting block is threadedly connected with a bolt, and one end of the bolt abuts against the electrode inserted in the assembly groove.

[0009] Preferably, a card slot is opened on one side of the bottom surface of the base, and a positioning hole is opened on the top surface of the base, and the positioning hole extends to the card slot and is communicated with the card slot.

[0010] Preferably, the thickness of the connecting block is the same as the thickness of the base, and the two surfaces of the connecting block are flush with the two surfaces of the base.

[0016] 2. The present utility model assembles the installation structure at both ends of the substrate and aligns the electrodes on the installation structure with the verification reference block to complete the use between the installation structure and the fixture.

[0022] The following will elaborate on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0023] The present utility model provides a resistance welding electrode mounting structure and a quick installation and verification jig. As Figures 1-4 shown, it includes a base 1 and an electrode 4 mounted on the base 1. One of the corners of the base 1 fits with an assembly block 2, and assembly grooves that are mutually adapted are provided at the corners where the base 1 contacts the assembly block 2 for assembling the electrode 4. A connecting block 3 is detachably provided on another side of the base 1. One end of the connecting block 3 is threadedly connected with a bolt 5, and one end of the bolt 5 abuts against the electrode 4 inserted in the assembly groove.

[0024] By means of the provided adjustment hole 12, the electrode 4 is clamped and fixed, and the bolt 5 threadedly connected with the connecting block 3 abuts against the electrode 4. When the bolt 5 is rotated, the bolt 5 feeds, so as to eject one end of the electrode 4. This not only facilitates the fixation of the electrode 4, but also provides convenience for the adjustment of the electrode 4, and the threaded feed is more precise, greatly improving the adjustment progress of the electrode 4.

[0025] Further, a card slot 6 is provided on one side of the bottom surface of the base 1, and a positioning hole 7 is provided on the top surface of the base 1, and the positioning hole 7 extends to the card slot 6 and is communicated with the card slot 6.

[0026] Further, the thickness of the connecting block 3 is the same as the thickness of the base 1, and both sides of the connecting block 3 are flush with both sides of the base 1, so that the connecting block 3 and the base 1 are fixedly installed on the jig flatly.

[0027] A quick installation and verification jig includes a substrate 8. Two symmetric grooves 10 are provided on the top surface of the substrate 8. A verification reference block 11 is provided inside each groove 10. An installation structure is assembled at each of the left and right ends of the substrate 8, and the electrode 4 on the installation structure corresponds to the verification reference block 11 left and right.

[0028] The installation structure is assembled at both ends of the substrate 8 and the electrode 4 on the installation structure is aligned with the verification reference block 11 to complete the use between the installation structure and the jig. Before verification, the verification reference block 11 is fixedly installed in the groove 10, and the distance between the verification reference block 11 and the installation structure is set to the required length of the electrode 4. When adjusting the length of the electrode 4, only need to rotate the bolt 5 to feed the electrode 4 until the electrode 4 abuts against the verification reference block 11. No measuring tool is required, which not only ensures the adjustment accuracy of the electrode 4, but also can quickly complete the verification work of the electrode in large batches, greatly improving the convenience of adjusting the electrode 4.

[0029] Furthermore, positioning plates 9 that are adapted to the card slots 6 can be detachably installed at both ends of the top surface of the substrate 8. The positioning plates 9 are used to connect to the base 1 of the installation structure. The base 1 is snap-fitted with the positioning plates 9 by means of the card slots 6 provided, and the base 1 is firmly fixed on the substrate 8 by means of the threads connected to the positioning holes 7, ensuring the stability of the installation structure.

[0030] Furthermore, a plurality of equally spaced adjustment holes 12 are provided inside the groove 10. The calibration reference block 11 is fixed to the adjustment holes 12 by screws. The calibration reference block 11 can be adjusted in position within the groove 10 by means of the plurality of adjustment holes 12 and the screws according to the length of the electrode, so as to meet the calibration of electrodes 4 of different lengths, thereby improving the practicability of the installation structure and the jig.

[0031] The working principle of the present utility model:

[0032] First, before calibration, the calibration reference block 11 is fixedly installed in the groove 10, and the distance between the calibration reference block 11 and the installation structure is set to the length required by the electrode 4.

[0033] Then, the electrode 4 is inserted into the assembly groove formed by the base 1 and the assembly block 2 and fixed with screws. At the same time, the bolt 5 is screwed so that the bolt first contacts one end of the assembly block 4.

[0034] Finally, the base 1 is snap-fitted with the positioning plate 9 on the substrate 8 by means of the card slot 6 provided, and then screws are screwed and fixed at the positioning holes 7.

[0035] During calibration, only need to screw the bolt 5 to gradually advance, so that the bolt 5 abuts against the electrode 4 and moves in the direction of the calibration reference block 11 until the electrode 4 abuts against the calibration reference block 11. There is no need for measuring tools, which not only ensures the adjustment accuracy of the electrode 4, but also can quickly complete the calibration work of the electrode in large batches, greatly improving the convenience of adjusting the electrode 4.
