Description

Technical Field

[0001] This invention relates to a device for detecting the hole spacing of a control box busbar. Background Technology

[0002] Currently, there are many types of busbars for control boxes, with different shapes and sizes, and all of them are irregular shapes. The mounting holes of most busbars are distributed on parallel but different planes with varying diameters. Ordinary testing tools cannot measure their hole spacing, which makes it difficult to guarantee product quality. During use, problems such as the inability to assemble the product due to out-of-tolerance hole spacing can easily occur. The existing measurement method is to measure the hole spacing using hole spacing gauges, but there are many types of dedicated hole spacing gauges, which are costly to manufacture, have long production cycles, and low testing efficiency.

[0003] For example, CN209716188U discloses a simple punching die with adjustable hole spacing. By fixing the punching die on a slider, the position of the punching die can be precisely adjusted by the slider. However, its positioning method of the slider requires the installation of multiple positioning bolts on the base plate, and it cannot measure the hole spacing. Summary of the Invention

[0004] The purpose of this invention is to address the problem of difficulty in measuring the hole diameter of existing busbars. This invention uses X-axis and Y-axis sliders to accurately position the two through holes of the busbar.

[0005] The technical solution of the present invention: A control box busbar hole spacing detection device includes a base; both ends of the base are provided with bosses, which are connected by a ball screw and a slide bar. An X-axis slider is installed on the ball screw and the slide bar, and a Y-axis slider is installed on the X-axis slider. A first detection pin and a second detection pin are vertically installed on the top of the boss at one end of the base and the top center of the Y-axis slider, respectively. One end of the ball screw extends out of the base and is equipped with a handwheel. Scales are provided on the side of the base and the top of the side of the X-axis slider.

[0006] The ball screw is installed in the middle of the boss, and a rolling bearing is installed inside the boss to support the ball screw.

[0007] A sliding sleeve is also installed between the ball screw and the rolling bearing.

[0008] The slide rod consists of two rods, with both ends fixed to the boss and symmetrically arranged on both sides of the ball screw, parallel to the ball screw.

[0009] The X-axis slider has through holes machined in the middle and at both ends, corresponding to the positions of the slider and ball screw. One end of the middle through hole is fixed with an internal threaded sleeve.

[0010] The top of the X-axis slider is machined with a slide rail along its length.

[0011] The base is also equipped with a lead screw fixing block. A through hole is machined in the center of the lead screw fixing block. The part of the ball screw extending out of the base is placed in the through hole. The lead screw fixing block is machined with a threaded through hole. A locking screw is installed in the threaded through hole. A locking handle is fixed on the top of the locking screw.

[0012] The scale on the side of the base is 0 with the center line of the first detection pin as the 0 mark, and the scale on the side of the X-axis slider is 0 with the center line of the slider rod as the 0 mark. The center line of the slider rod intersects with the center line of the first detection pin.

[0013] The first and second detection pins are removable.

[0014] The two end faces of the X-axis slider are on the same plane as the side of the base, and the end faces are provided with scales, with the 0 scale located on the center line of the X-axis slider. The two end faces of the Y-axis slider are on the same plane as the side face of the X-axis slider, and the end faces are engraved with scales, with the 0 mark located on the center line of the end face of the Y-axis slider.

[0015] The beneficial effects of this invention are: It can measure the hole spacing on the same or different planes, and manifold products with different hole diameters and hole spacing dimensions. It can also be applied to the detection of hole spacing of other products. As long as it is within the detection stroke and accuracy range, it can be detected. It has a simple structure and is easy to operate, which greatly speeds up production efficiency. Attached Figure Description

Detailed Implementation

[0020] Example 1: like Figure 1As shown, the hole spacing detection device of the present invention adopts a combined structure, mainly divided into three parts: base, slider assembly and lead screw assembly. The slider assembly consists of an X-axis slider, a Y-axis slider, a sliding rod, detection pin 1, detection pin 2, and a set screw. The two ends of the two sliding rods are connected to the two ends of the base and fixed by the set screw. The X-axis slider is installed on the two sliding rods in a through manner, and the Y-axis slider is installed on the X-axis slider in a groove manner. Both the base and the Y-axis slider are designed with detection pin mounting holes. The detection pins are all designed as stepped, with the small end diameter being consistent. They are installed on the base and slider in a sliding fit manner. Both the base and the slider are designed with set screws to fix the detection pins. Additionally, the lead screw assembly consists of a ball screw, rolling bearings, a handwheel, a lead screw fixing block, and a set screw handle. Two rolling bearings are respectively installed and fixed at both ends of the base. The two ends of the lead screw are connected to the rolling bearings and fixed with set screws. The nut part of the lead screw is designed with mounting holes and is connected and fixed to the X slider with screws. The handwheel is installed at one end of the lead screw. Rotating the handwheel can make the lead screw rotate, and the lead screw converts the rotary motion into linear motion, so that the X slider can move left and right in the X direction. The lead screw fixing block is installed on the base and clamps one end of the lead screw. The set screw handle is installed on the lead screw fixing block and works with the lead screw fixing block to control the rotation of the lead screw.

[0021] Taking the hole spacing of a certain model of busbar in a control box as an example, as shown in the attached diagram, the size and specifications of the detection pins are selected according to the diameter of the hole to be tested and the height of the different planes they are located on. The placement direction of the product is determined according to the product shape and the distribution direction of the holes to be tested. According to the hole spacing dimensions of the holes to be tested in the product process drawing, the coordinate dimensions of detection pins 1 and 2 of the detection device are determined, i.e., detection pin 1 (0, 0) and detection pin 2 (127.5, 39.7). Detection pins 1 and 2 are installed in the designated mounting holes and fixed with set screws. The X-axis slider is moved by rotating the handwheel to move detection pin 2 to the designated position (X: 127.5), and its position is fixed with the set handle. Then, the Y-axis slider is moved to the designated position (Y: 39.7), and its position is fixed with the set screw. At this time, the X-axis reading is 127.5 and the Y-axis reading is 39.7. The holes to be tested of the product are aligned with the detection pins and placed in the designated direction in a natural state. If the product can pass through both detection pins smoothly at the same time, the hole spacing of the product is qualified.

[0022] When inspecting different product models, simply loosen the set screw of the fixed detection pin, replace it with the corresponding model detection pin, and then fix it. Next, loosen the set screw of the control screw and the set screw of the fixed slider. According to the product model and size, readjust the coordinate position of the detection pin, and then fix the position. Then you can proceed with the hole spacing inspection of the next product model.

[0023] The steps for hole spacing detection are as follows: Step S1: Select the size and specifications of the detection pin according to the diameter of the hole to be tested and the height of the different planes on which it is located; Step S2: Determine the product placement direction based on the product shape and the distribution direction of the holes to be tested; Step S3: Determine the X and Y axis slider coordinate dimensions of the detection device based on the hole spacing dimensions of the holes to be measured in the product process drawing; Step S4: Fix the detection pins in the designated positions, move the X and Y sliders to move the detection pins 2 to the designated X and Y coordinate positions, and then fix the positions. Step S5: Align the product's inspection hole with the inspection pin and place it in the specified direction in a natural state. If the product can pass through both inspection pins smoothly at the same time, the product's hole spacing is qualified.

[0024] The hole spacing detection device of this invention adopts a modular structure. According to the diameter and spacing of the hole to be inspected in the product, the diameter and distance of the detection pin can be freely adjusted. Select a certain model of product, adjust the size and position of the detection pin, and then fix it in place. At this time, the detection device is equivalent to a special hole spacing gauge. While ensuring the detection accuracy is the same as that of a special hole spacing gauge, it improves the flexibility of detection.
