Description

Technical Field

[0001] This utility model relates to the field of product testing technology, specifically to a symmetry testing tool for double-flat connectors. Background Technology

[0002] For double flat through-hole connectors (such as...) Figure 1 As shown in the figure, the most widely accepted measurement method for determining symmetry relationships is coordinate measuring machine (CMM). This method uses multiple contact points to locate and fit a 3D model before determining the positional relationships. The more contact points there are, the closer the fitted 3D model will be to the actual state, and the more accurate the measurement results will be. However, the more points are taken, the longer the determination process becomes. In CNC machining processes that require multiple parameter adjustments, the time-consuming nature of CMM leads to high time costs.

[0003] To accurately measure the symmetry value under actual working conditions, thereby adjusting parameters in a timely manner and reducing time costs, it is urgent to design a detection tool for the symmetry of the holes in this connector. Summary of the Invention

Each of the positioning structures includes a positioning seat, a support block, and a positioning pin. The positioning seat is disposed on the base plate, the support block is disposed on the positioning seat and located on the side close to another positioning structure, and the positioning pin is vertically disposed on the positioning seat. The measuring structure includes a limiting block, a bracket, and a dial indicator. The limiting block is disposed on the positioning seat, the bracket and the positioning pin are slidably engaged and abut against the limiting block, and the dial indicator is disposed on the bracket.

[0005] Furthermore, the center lines of the positioning seat, the support block, and the positioning pin are on the same vertical plane.

[0006] Furthermore, the limiting block is inverted L-shaped, and includes a vertical connecting part and a horizontal supporting part. The bottom end of the vertical connecting part is connected to the positioning seat, and the horizontal supporting part is disposed at the top end of the vertical connecting part.

[0007] Furthermore, there are two limiting blocks, one of which is located on one of the positioning seats.

[0008] Furthermore, the frame structure also includes a pair of handles, which are respectively disposed on both sides of the base plate.

[0009] Furthermore, the frame structure also includes a guide rail pair, which is disposed on the base plate and connects the two frame structures respectively.

[0016] like Figure 2-3 As shown, this embodiment provides a symmetry detection tool for a double-flat connector 4, including: a frame structure, a pair of positioning structures and a measuring structure; The frame structure includes a base plate 11, and two positioning structures are slidably disposed on the frame structure. The two positioning structures fix one end of the connector 4 respectively. Depending on the size of the connector 4, the two positioning structures can be slidably adjusted to meet the detection requirements of the connector 4 and improve versatility.

[0017] Each of the positioning structures includes a positioning seat 21, a support block 22, and a positioning pin 23. The positioning seat 21 is disposed on the base plate 11, and the support block 22 is disposed on the positioning seat 21 and located on the side close to another positioning structure. The support block 22 is used to support the bottom of the connector 4. The positioning pin 23 is vertically disposed on the positioning seat 21, and the through hole of the connector 4 is sleeved on the positioning pin 23 to achieve horizontal positioning.

[0018] The measuring structure includes a limiting block 31, a bracket 32, and a dial indicator 33. The limiting block 31 is disposed on the positioning seat 21. The bracket 32 ​​and the positioning pin 23 are slidably engaged and abut against the limiting block 31. The dial indicator 33 is disposed on the bracket 32. The limiting block 31 provides a reference height for the dial indicator 33 during measurement.

[0019] Furthermore, the center lines of the positioning seat 21, the support block 22, and the positioning pin 23 are on the same vertical plane.

[0020] Furthermore, the limiting block 31 is inverted L-shaped and includes a vertical connecting part 311 and a horizontal support part 312. The bottom end of the vertical connecting part 311 is connected to the positioning seat 21, and the horizontal support part 312 is disposed at the top end of the vertical connecting part 311 to support the bracket 32. In this way, while the limiting block 31 provides support for the bracket 32, it does not interfere with the positioning pin 23.

[0021] In this embodiment, two limiting blocks 31 are provided, with one limiting block 31 on each positioning seat 21; this avoids deviations caused by the limiting blocks 31 during disassembly and installation, and ensures the uniformity of the reference.

[0022] Furthermore, the frame structure also includes a pair of handles 12, which are respectively disposed on both sides of the base plate 11 to facilitate manual extraction and transfer.

[0023] Furthermore, the frame structure also includes a guide rail pair 13, which is disposed on the base plate 11 and connects the two frame structures respectively, thereby realizing a sliding fit between the frame structures and the base plate 11. Preferably, one of the two frame structures is fixedly connected to the other slidingly, or both are slidably connected.

[0024] Furthermore, the positioning structure also includes a magnet 24, which is disposed on the positioning seat 21 and located on a side surface close to the other positioning structure, with the opposing sides of the two magnets 24 having the same pole. Under the condition of magnetic repulsion, the axially movable positioning pins 23 at both ends will be tangent to the edge of the hole in the connector 4, and the dial indicator 33 is placed on the positioning pins 23, achieving relative fixation of the measurement reference and ensuring the accuracy and consistency of the measurement.

[0025] In this embodiment, the support block 22 provides a horizontal reference for the connector 4, and the limiting block 31 supports the dial indicator 33, providing another horizontal reference for the dial indicator 33. The dial indicator 33 measures the height difference between the two arc surfaces of the connector 4 to determine the symmetry of the connector 4, thus enabling fast and convenient testing.

[0026] The specific steps are as follows: 1. Align the two through holes of the flat part of the connector 4 with the two positioning pins 23 and insert it, and the straight section of the rod of the connector 4 must be flat against the support block 22; 2. Align the bracket 32 ​​with one of the positioning pins 23 and place it flat against the limiting block 31. The pointer of the dial indicator 33 touches the arc surface of the connector 4. Set the reading of the dial indicator 33 to zero. 3. Take out the bracket 32, place it on another positioning pin 23, and flatten it with the corresponding limiting block 31. After the pointer of the dial indicator 33 touches the arc surface of the connector 4, directly read the value to confirm whether the symmetry is qualified.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
