Description

Technical Field

[0001] The invention relates to the technical field of calibration jigs, and in particular to a copper busbar bracket calibration jig. Background Art

[0002] Copper busbars, also known as copper busbars, copper busbars or copper busbars, are made of copper and play the role of transmitting current and connecting electrical equipment in the circuit, such as in large distribution boxes, large machine rooms or large substations. The existing copper busbar brackets are mostly used in a trapezoidal structure. At this stage, the copper busbar brackets are installed on the output end of the current through the positioning mounting holes at both ends, and then fixed with fixing bolts to achieve the positioning installation of the copper busbar. After installation, the copper busbar bracket uses the copper busbar holes to conveniently install the cable. During the production process, the copper busbar needs to use a copper busbar inspection jig to check the hole spacing or The aperture is inspected, but the traditional copper busbar inspection fixture generally only has a single hole spacing inspection function or a single aperture inspection function. Generally, two different inspection fixtures are required to measure the hole spacing of the copper busbar installation holes and the adjacent aperture sizes respectively. The operation is time-consuming and labor-intensive, which increases the inspection process, wastes manpower costs, and reduces the inspection efficiency. In addition, different specifications of copper busbars produced in different workshops need to be equipped with different calibration jigs to calibrate the aperture or hole spacing. The adaptability of existing calibration jigs is relatively low. Different specifications of copper busbars need to be equipped with different calibration jigs, which increases the production cost of the enterprise. Summary of the invention

[0017] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0018] 1. Use the two sets of fixing grooves and fixing blocks on the fixing column to clamp and position the copper busbar brackets of products with different specifications. Use the screw hole positioning rods on the fixing blocks to position and clamp the mounting holes at both ends of the copper busbar bracket body, which is convenient for positioning and verification of the copper busbar bracket.

The manual rotation operation is convenient for adjusting and controlling the state of the calibration frame 5 to achieve stable hole spacing and aperture calibration.

[0049] Working principle: before use, the entire calibration jig is adjusted, and the position of the fixed column 2 is adjusted by operating the adjusting rotating disk 34 using the bidirectional screw 31, the adjusting block 32, the movable rod 35, the base rod 33 and the limiting groove 36. The copper bar bracket body 1 is adjusted in height by entering into different fixing grooves 21 through the fixing block 24, so that the mounting holes at both ends of the copper bar bracket body 1 can enter into the screw hole positioning rod 26. At the same time, the quick clamp 23 on the fixing column 2 can press the copper bar bracket body 1 at both ends, so as to realize the convenient positioning of the hole diameter and hole spacing of the copper bar bracket body 1 for calibration, and meet the calibration of copper bars of different specifications at the same time;

[0051] During the verification, the copper bar bracket can be replaced by operating the rotating adjustment disk and the quick clamp 23. The fixed column 2 moves similarly under the rotation of the rotating adjustment disk to realize the removal of the copper bar bracket. The fixed column 2 moves in the opposite direction to realize the positioning of the copper bar bracket, and it is centered.

[0052] The lifting rotary disk 66 is operated to drive the calibration frame 5 to continuously rise under the action of the lifting screw 61, the lifting block 62, the lifting rod 68, the first bevel gear 63, the second bevel gear 64 and the lifting rotary disk 66. The first calibration column 71 and the second calibration column 76 on the calibration frame 5 realize the hole spacing calibration of the holes on the copper busbar bracket. If the calibration column can be inserted into the hole, it can be judged that the hole spacing is qualified. If it cannot be inserted, it is unqualified. After the hole spacing is judged to be qualified, the lifting rotary disk 66 is continuously operated to make the first calibration column 71 or the second calibration column 76 pass through the hole. When the calibration ring on the outer periphery of the bottom of the calibration column is pressed down, it can be judged that the aperture is qualified.

[0053] After the calibration, operate the adjustment rotary disk 34 to move approximately, open the quick clamp 23 to remove the copper bar bracket, then put in the next copper bar bracket to be calibrated, rotate the adjustment rotary disk 34 to make the new copper bar bracket centered, and repeat the calibration operation.
