Description

Technical Field

[0001] The present technical solution relates to the technical field of inspection tools, and in particular to a hole position inspection tool. Background Art

[0002] A hole detection fixture, also known as a hole gauge, is a tool used to detect whether the holes of porous parts are qualified. This fixture is usually used in the manufacturing process of parts that require precise control of the hole position.

[0003] The existing method of measuring hole positions requires measuring two holes with a caliper. The size measurement requires measuring the minimum distance between the two holes and the maximum distance between the two holes. Then, the average of the minimum distance value and the maximum distance value is taken to obtain the distance between the two center points. For the existing workpieces, see Figure 5 , including a connecting rod 100 and two side rods 200, the connecting rod 100 is connected between the two side rods 200, and each side rod 200 has an end tube portion 300 at one end away from the connecting rod 100, each end tube portion 300 is penetrated by a through hole 400, and there are two through holes 400, and the two through holes 400 are spaced apart along the length direction of the end tube portion 300.

[0004] The above-mentioned method of measuring hole positions requires multiple distance measurements between two hole positions, and the obtained values ​​are compared after calculation. There are many steps to obtain the distance between the two holes, and the operation is cumbersome and needs to be improved. Summary of the invention

[0005] In order to improve the problem of complicated operation of existing hole distance measurement, this technical solution provides a hole position detection fixture.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A hole position detection fixture comprises a mounting frame, the mounting frame is provided with a detection component, the detection component comprises a measuring block, a positioning block and a sliding drive member, the measuring block is slidably connected relative to the mounting frame, the positioning block is located below the mounting frame along the sliding direction of the measuring block, two detection rods are provided on the end surface of the measuring block facing the positioning block, and the sliding drive member is used to drive the measuring block to approach the positioning block so that the two detection rods are embedded in the through hole of the workpiece.

[0008] Through the above technical scheme, when the hole position detection fixture is used normally, the workpiece is placed on the mounting frame to ensure that the end tube portion of the side rod is against the positioning block to improve the accuracy of positioning, and the positioning block is used to support the end tube portion. Based on the positioning block being located below the mounting frame along the sliding direction of the measuring block, the through hole position of the end tube portion is facing the two detection rods of the measuring block, and the sliding drive member drives the measuring block to gradually approach the end tube portion on the positioning block along the vertical sliding direction. The positions of the two detection rods are designed to correspond to the through holes one by one, and the positions of the two detection rods are calibrated to accurately match the compliant through holes. When the two detection rods are fully embedded in the through holes, the two detection rods represent the actual distance between the two hole positions of the workpiece. When the two detection rods are interfered or cannot be embedded, the hole position of the end tube portion does not meet the standard, thereby achieving fast and accurate measurement of the hole position, improving measurement efficiency, and thus improving the convenience of measurement operation.

[0009] Preferably, a positioning groove is provided on the end surface of the positioning block facing the measuring block, and the positioning groove is adapted to the end tube portion for embedding and positioning the end tube portion.

[0010] Through the above technical solution, the shape and size of the positioning groove are adapted to the end pipe part, and the end pipe part is positioned by embedding the positioning groove so that it can be quickly and accurately placed at the detection position, avoiding measurement errors caused by shaking or displacement of the end pipe part during the detection process, so that the end pipe part maintains a stable position to ensure the accuracy of the detection results, thereby further improving the detection efficiency.

[0011] Preferably, the measuring block is provided with a measuring groove, the measuring groove is located at the end surface of the measuring block facing the positioning groove, the two detection rods are both arranged at the bottom of the measuring groove, and when the measuring block and the positioning block are close to each other, the measuring groove and the positioning groove are spliced ​​with each other.

[0012] Through the above technical scheme, after the end tube portion is embedded in the positioning groove, the sliding drive member drives the measuring block to move close to the positioning block, and the measuring groove is adapted to the upper end of the end tube portion protruding from the positioning groove. Based on the fact that two detection rods are both arranged at the bottom of the measuring groove, the detection rods are embedded in the through hole, so that the measuring groove gradually approaches the positioning groove until the two are completely spliced. At this time, the end tube portion is embedded in the measuring groove and the positioning groove at the same time, further improving the accuracy of the positioning of the end tube portion.

[0013] Preferably, the detection assembly is provided with two cushion plates, which are detachably connected to the positioning block and the measuring block in a one-to-one correspondence, and the side walls along the insertion direction of the end tube portion are used for the side rods to abut against.

[0014] Through the above technical solution, based on the detachable connection of the two cushion plates, by removing and replacing different cushion plates, the different thicknesses of the cushion plates enable the workpiece to adjust the length range of the embedded positioning groove and the measuring groove, thereby aligning the hole position with the two detection rods, thereby improving applicability. The cushion plates are arranged on the side walls to form a buffer layer between the side rod and the positioning block and the measuring block, thereby reducing the bumps or damages caused to the side rod during the insertion of the end pipe, thereby ensuring the quality of the workpiece and improving its integrity.

[0015] Preferably, the sliding drive member is provided with a mounting seat, the mounting frame is provided with a mounting hole, and the lower end of the mounting seat is inserted into the mounting hole to fix the sliding drive member on the mounting frame.

[0017] Preferably, two detection components are provided, and the two detection components are symmetrically distributed along the mounting frame and are arranged away from each other.

[0018] Through the above technical solution, two detection components that are separated from each other are set. The detection components can adopt push-pull quick chucks to avoid the relative influence of the detection components on the push-pull operation. Through the symmetrical arrangement of the two detection components, the two side rods on both sides of the connecting rod can be detected at the same time, thereby shortening the detection time and improving the detection efficiency.

[0019] Preferably, the mounting frame is provided with two support seats, the two support seats correspond one to one with the two detection components, the upper end surface of the support seat is provided with a catheter groove, and the catheter groove is aligned with the positioning groove for the end pipe part to be embedded.

[0020] Through the above technical solution, when the end tube is embedded in the positioning groove, since the positioning groove is aligned with the catheter groove, the shape and size of the catheter groove are adapted to the side rod, and the side rod is embedded in the catheter groove at the same time so that the support seat provides support for the side rod, and the support seat cooperates with the positioning block to improve the stability of the side rod.

[0021] Preferably, the mounting frame is provided with a plug hole, and the plug hole is used for the lower end of the support seat to be embedded and positioned.

When the measuring block and the positioning block are close to each other, the measuring groove and the installation groove are spliced ​​with each other. At this time, the end tube part is embedded in the measuring groove and the positioning groove at the same time, thereby further improving the accuracy of the positioning of the end tube part.
