Description

Technical Field

[0001] The utility model belongs to the technical field of inspection tools, and in particular relates to a high-precision inspection tool for a busbar insulation bracket of a switch cabinet. Background Art

[0002] The switch cabinet busbar bracket is an insulating component designed for carrying, connecting, and suspending IGBT modules, integrated busbar modules, cable harnesses, etc. in the switch cabinet. Its working conditions require that the parts must have high precision, high strength, insulation, and voltage resistance. Switch cabinet products are used in outdoor equipment such as photovoltaic power stations, wind farms, and offshore photovoltaic power stations. They need to be transported over long distances in a dynamic transportation state, requiring intensive miniaturization and modular development of parts. In addition, the installation and use space in the cabinet is limited, and products with size deviations cannot be installed, which will lead to overall deviations in the equipment and ultimately scrap the product. And because the insulating parts are rigid materials, if there are problems with the hole position and angle, the various modules suspended / carried / connected by the insulating parts will generate lateral tension, causing the angle steel to break.

[0003] Therefore, special inspection tools are needed to measure and evaluate the size and quality of parts. Inspection tools are devices used to inspect workpieces during machining. Existing inspection tools are cumbersome to operate and require manual replacement of inspection tools or transfer of workbenches to inspect workpieces, which increases processing time, increases labor intensity, and reduces production and processing efficiency.

[0028] Reference Figure 1-5 As shown, a high-precision detection tooling for a switch cabinet busbar insulation bracket includes a detection base plate 1 and a detection rear plate 2, wherein the lower side of the detection rear plate 2 is vertically connected to the rear end of the detection base plate 1, and a first positioning hole 21 consistent with the detection hole 41 of the workpiece 4 is correspondingly opened on the surface of the detection rear plate 2, and the first positioning hole 21 is provided with a first detection pin 22; a second positioning hole 11 consistent with the detection hole 41 of the workpiece 4 is correspondingly opened on the surface of the detection base plate 1, the second positioning hole 11 is a square hole, and the second positioning hole 11 is provided with a second detection pin 12, the lower end of the second detection pin 12 is a positioning pin 121 consistent with the square hole, and the upper end of the second detection pin 12 is a detection column 122 consistent with the second positioning hole 11, and a third positioning hole 13 consistent with the detection hole 41 on the side of the workpiece 4 is correspondingly opened on the side of the detection column 122, and the third positioning hole 13 is provided with a third detection pin 131.

[0029] By setting positioning holes corresponding to the holes 41 to be detected on the detection base plate 1 and the detection rear plate 2, the detection base plate 1 and the detection rear plate 2 are vertically spliced ​​and fit with the L-angle workpiece 4, each positioning hole is aligned with the corresponding detection hole 41, and then the corresponding detection pin is inserted into the positioning hole through the detection hole 41; during installation, it is necessary to first insert the positioning pin 121 of the second detection pin 12 into the second positioning hole 11, and then insert the detection hole 41 corresponding to the L-angle workpiece 4 into the detection column 122 to complete the placement of the L-angle workpiece 4.

[0030] The lower end of the second detection pin 12 is set as a square positioning pin 121, which can quickly match the third positioning hole 13 with the detection hole 41 on the side of the L-angle workpiece 4 without rotating the second detection pin 12 to align the holes, thereby reducing the operation difficulty and improving the detection speed.

[0031] Furthermore, an avoidance groove 23 is provided at the right angle where the detection rear plate 2 and the detection bottom plate 1 are vertically connected.

[0032] During the inspection, it was found that the hole positions of some workpieces 4 could not accurately correspond to the inspection fixture, resulting in data errors; however, the dimensions of the parts measured manually were qualified. After inspection, it was found that during the inspection, some of the dust on the parts would enter the connection between the inspection back plate 2 and the inspection bottom plate 1, resulting in the parts and the inspection fixture not being accurately fitted, and the hole positions not being accurately corresponding, resulting in unqualified test data; therefore, by adding an avoidance groove 23, the interference of dust on the inspection was reduced.

[0033] Further, the first detection pin 22 is a 11.26 mm detection pin, the second detection pin 12 is a 15.86 mm detection pin, and the third detection pin 131 is a 3.92 mm detection pin.

[0034] The aperture size of the workpiece 4 is detected as needed, and a detection pin of a corresponding aperture size is designed for rapid detection and judgment.

[0035] Furthermore, a guide column 123 is provided at the upper end of the detection column 122 .

[0036] When the L-angle workpiece 4 is installed, the second detection pin 12 will be blocked. By providing the guide column 123, alignment can be performed more quickly.

[0037] Furthermore, the guide column 123 is in a cone or frustum shape, which is conducive to quickly installing the L-angle workpiece 4 on the second detection pin 12 .

[0038] Furthermore, an angle detection mechanism 3 is provided on the detection base plate 1, and the angle detection mechanism 3 is provided with a base plate 31, a guide rail 32, a sliding block 33, a fixed seat 34, a slide rail 35, a slider 36 and an angle ruler 37. The guide rail 32 is arranged on the base plate 31 parallel to the first detection pin 22, the sliding block 33 is arranged on the guide rail 32, and the detection base plate 1 is fixed on the sliding block 33; the two ends of the slide rail 35 are vertically arranged on the side of the detection base plate 1 away from the detection rear plate 2 through the fixed seat 34, the slider 36 is arranged on the slide rail 35, and the angle ruler 37 is arranged on the slider 36.

[0039] By adjusting the detection base plate 1 set on the guide rail 32, that is, the L-angle workpiece 4, and adjusting the angle ruler 37 set on the slide rail 35, the angle ruler 37 is made to fit the inclined surface of the L-angle workpiece 4 that needs to be detected, so as to measure the inclined surface angle and the angle of the detection hole 41 corresponding to the third detection pin 131.

[0040] Furthermore, the angle ruler 37 is provided with a protractor 371 and a ruler 372, the protractor 371 is fixed on the slider 36, and the middle part of the ruler 372 is hinged to the center of the protractor 371; one end of the ruler 372 points to the scale of the protractor 371, and the side surface of the other end is parallel to the detection edge 42 of the workpiece 4, and a positioning groove 373 is provided on the top.

[0041] After adjusting the positions of the L-angle workpiece 4 and the angle ruler 37 by means of the guide rail 32 and the slide rail 35, the ruler 372 is rotated to make it fit with the detection bevel of the L-angle workpiece 4 to detect the angle of the bevel; then the positioning groove 373 at the top is docked with the third detection pin 131 to detect the angle of the side hole of the L-angle workpiece 4. Since the ruler 372 is perpendicular to the third detection pin 131, the actual angle is the value of the ruler 372 plus 90°.

[0042] Furthermore, the positioning groove 373 is an arc-shaped groove that matches the third detection pin 131 .

[0043] The arc-shaped slot engages with the third detection pin 131 to obtain the angle value more accurately.

[0044] Furthermore, a vernier scale is provided at the protractor 371 end of the ruler 372 .

[0045] By setting the vernier scale, you can obtain the angle value more accurately, providing a reference for modifying the processing parameters.

[0046] Furthermore, the scales at both ends of the protractor 371 are zero, the measuring range is 0-90°, the center of the corresponding vernier scale is zero and vernier scales are marked on both sides.

[0047] By setting symmetrical scale values, it is convenient to measure the angles of the two side surfaces of the L-angle workpiece 4.

[0048] During inspection, first insert the positioning pin 121 of the second inspection pin 12 into the second positioning hole 11 of the inspection base plate 1, and then insert the inspection hole 41 corresponding to the L-angle workpiece 4 into the inspection column 122, so that the L-angle workpiece 4 fits with the inspection base plate 1, and observe and test whether the L-angle workpiece 4 fits with the inspection rear plate 2. Finally, insert the first inspection pin 22 and the third inspection pin 131 into the corresponding inspection hole 41 of the L-angle workpiece 4 and the first positioning hole 21 and the third positioning hole 13 respectively to detect the machining accuracy of each hole. When it is necessary to detect the angle, initially adjust the angle ruler 37 to the 60° position, slide the sliding block 33 and the slider 36, adjust the L-angle workpiece 4 and the angle ruler 37 to the appropriate position, and then observe the angle. The 60° angle can be measured together with the 120° angle. The positioning groove 373 at the top of the ruler 372 is fitted with the third detection pin 131. The side walls of the detection ruler 372 are parallel to each other and can be fitted with the detection edge 42 of the workpiece. As long as the 60° angle is accurate, and then one side of the detection ruler 372 is used to fit the detection edge 42 of the workpiece, the 120° angle can be calculated to achieve fast, simple and intuitive measurement.

[0049] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
