Description

A drilling positioning ruler for equipment wire clips

technical field

The utility model belongs to the technical field of design and manufacture of measuring tools, in particular to a drilling positioning ruler for equipment line clips.

Background technique

The equipment clamp is a common connecting device used to connect the lead wires and the outlet terminals of electrical equipment (such as transformers, switches, switches, transformers, wall bushings, etc.) on power equipment. According to the material, it can be divided into copper-aluminum equipment clamps and all-aluminum equipment clamps. According to the installation method, it can be divided into bolt equipment clamps and compression equipment clamps, which include connecting parts and terminal board parts.

The equipment clamps are generally not drilled when leaving the factory, and the maintenance personnel drill holes in the wiring board part according to the needs of the site. Drilling usually has one hole, two holes, four holes, etc., depending on the wiring board of the equipment to be connected. Drilling holes for equipment clamps generally require accuracy, centering, firmness, and beauty, and the most important thing is that they can be accurately and properly connected to the equipment.

Common equipment clamp drilling methods include scribe drilling method and template drilling method. Regardless of the type, it is necessary to locate the center sample in the hole on the wiring board, and then knock the center sample larger to facilitate accurate centering of the drill. These two methods are relatively cumbersome for the positioning center of the equipment clamp. First of all, the most commonly used method is the scribe drilling method. You can use a straightedge or square. Because the wiring board and the connecting part are not on the same level, there is a greater error; if you use a square, because only the horizontal part of the square has scales, there is a problem of direction. It is easier to find the center of the width, and the center of the length is because of the ruler The direction problem can only be used as a ruler, and the scale is on the upper half of the ruler. The scale is not counted from the right angle, and there are errors everywhere in the measurement. The method of locating the center sample is to first measure the length of the wiring board, take a point in the center, then take another point, and set a straight line at two points; then measure the width of the wiring board, use the same method to take two points, and then determine a straight line, two The intersection point of the two lines is the center sample of the clamp. If it is a one-hole line clip, the work is over; if it is two holes, it should be centered on the center sample, and then positioned with the required hole distance; if it is four holes, continue to draw lines on the basis of two holes. According to this calculation, one hole needs to measure the wiring board 4 times, scribe 2 times, two holes need to measure 4 times, scribe 4 times, four holes need to measure 8 times, scribe 6 times. Every time there is a slight error, it will have a great impact on the next step, resulting in the processed clamps being unusable due to the wrong hole size, which is time-consuming and labor-intensive. For a large number of processing, the work efficiency is too low (in special cases, it is not necessary to center the hole. , in a similar manner). The second is the template drilling method. This method is faster than the usual planning line drilling method. It is commonly used for 4 holes. Below 4 holes, the scribe drilling method is used. Use a scribe to draw the processing circle of the hole, and then punch out the drill with a sample punch. Hole center eye, this method also has many disadvantages. First, such center eye is basically knocked out based on experience, which cannot be accurately measured and drawn, and there are large errors. Second, in the actual installation process, the equipment line Due to the different devices connected, the clamps have different widths, such as 40mm, 50mm, 60mm, 80mm, 100mm, etc., and the hole pitches are 30mm, 35mm, 40mm, 60mm, etc. There are many requirements for templates, and it is not easy to buy in the market.

Portable, it is the right-hand man for electric maintenance workers.

The zero scale of the vertical ruler and the sliding ruler are on the same straight line, which can reduce measurement errors.

According to the utility model described in the equipment wire clip drilling positioning ruler, there is a height difference h between the side of the sliding ruler without scale and the same side of the chute, which is convenient for the alignment measurement of the wire clips and increases the accuracy.

The height difference of the drilling positioning ruler for the equipment wire clamp described in the utility model is preferably 3-4mm. Since the height difference is limited by the thickness of the abrasive tool and the thickness of the ruler, if the height difference is small, one is due to the side angle of the equipment wire clamp itself. It is not very neat, and it is not easy to align with the zero scale. Second, due to wear and tear during repeated use, the height difference will become smooth and not obvious, resulting in misalignment; if the height difference is large, the ruler will become thinner, which is stable for the entire ruler. The performance is affected, or the thickness of the abrasive tool is increased, which will increase the cost. The height difference is selected at 3-4mm, which not only ensures that the equipment clamps are easy to align with the zero scale, but also ensures the stability of the ruler.

According to the utility model described in the equipment wire clip drilling positioning ruler, the main ruler and the sliding ruler are made of 3Cr13 stainless steel, and the heat treatment hardness is HRC40-45, which increases the hardness and firmness of the ruler, and has higher strength and hardness. and wear resistance.

According to the drilling and positioning ruler for equipment wire clips described in the utility model, the thickness of the main ruler is 3 mm, and the thickness of the sliding ruler is 2 to 3 mm. If it is too thin, it will affect the overall stability of the ruler. The thickness of the main ruler is 3mm, and the thickness of the sliding ruler is 2mm~3mm, which not only saves costs, but also ensures the stability of the ruler.
