Description

Technical Field

[0001] The utility model relates to the field of torque testers, in particular to a tapping torque tester. Background Art

[0002] The tapping torque tester is a device used to measure the torque required during the tapping process. It is widely used in the fields of mechanical processing and manufacturing. Tapping is the process of machining internal threads on materials using threading tools. In this process, the torque of the tool is an important parameter that directly affects the processing quality and tool life. This instrument is widely used in automotive manufacturing, aerospace, electronics and other industries that require high-precision thread processing, helping companies improve production efficiency and product quality.

[0003] Existing tapping torque testers usually use manual tightening and loosening bolts with the help of external tools to achieve the effect of changing the tapping position of the test plate. Some tapping torque testers also use manual secondary cleaning of the tapping inner wall. After the tapping is completed, the tapping inner wall is manually cleaned using a cotton swab and test fluid to prevent the tapping test from causing large errors due to burrs or debris.

[0004] On the one hand, the existing method of changing the tapping position by fixing with bolts is relatively cumbersome, requiring manual repeated loosening and tightening of two sets of bolts to change the horizontal and vertical movement positions. It is impossible to release the limit of bidirectional movement of a single unit at the same time, and the testing efficiency is low. On the other hand, the existing method of manually cleaning the inner wall of the tapping requires manual cleaning after the tapping is completed, and it is impossible to clean the inner wall simultaneously with the tapping process. Therefore, a tapping torque tester is proposed to solve the above problems. Utility Model Content

The top of the outer wall of the tapping machine 10 is fixedly connected to the lower surface of the top of the outer wall of the instrument base 1. The tapping machine 10 is a prior art and will not be described in detail. It is used to drive the tapping tool to rotate and move downward. A dust collector 11 is fixedly connected to the right side of the outer wall of the tapping machine 10. The dust collector 11 is a prior art and will not be described in detail. It is used to move up and down synchronously with the tapping machine 10. A dust collection pipe 12 is fixedly connected to the bottom of the outer wall of the dust collection machine 11.

The opposing extrusion force between the limiting spring 19 and the movable plate 3 ensures that the limiting block 18 is always clamped on the inner wall of the limiting groove 16 without being affected by external forces.

[0035] Working principle: When adjusting the tapping position of the test plate 8, the limit is released by manually pulling the limit rod 17 out of the limit hole 20, and at the same time, the limit block 18 is driven to disengage from the limit groove 16 to release the limit. Then, the movable plate 3 is manually moved horizontally or the fixed plate 6 is moved vertically to the required tapping position. After that, the limit rod 17 is released and the limit spring 19 is used to rebound the limit rod 17 to the corresponding inner wall of the limit hole 20 for engagement. At the same time, the limit block 18 is driven to rebound to the inner wall of the corresponding limit groove 16 for engagement through the limit rod 17, thereby realizing the single-unit release of two sets of limits, and providing for the simultaneous vertical and horizontal adjustment of the tapping position, thereby greatly improving the test efficiency.

[0036] During the tapping operation, the tapping machine 10 and the vacuum cleaner 11 are turned on, the tapping operation is performed by lowering the tapping machine 10, and then the vacuum cleaner 11 is driven to lower by the tapping machine 10, and the vacuum cleaner 11 drives the dust collection pipe 12 to enter the tapped inner wall at intervals of one tapping hole to perform suction and cleaning operations, so that the debris generated by the tapping is sucked out of the tapped inner wall, and at the same time, the protective cover 14 is made to fit the test plate 8 by compressing the spring 13 to avoid the debris generated by the tapping from splashing, thereby reducing the time for manual cleaning and testing and improving the test efficiency.
