The precision of the assembly hole arranged on a certain position of the workpiece is crucial, and deviation in the position or depth of the hole will directly lead to subsequent assembly failure, so after the workpiece production is completed, a special gauge or a professional measuring tool needs to be used to detect the machining position and depth of the hole.

[0003] For example, a kind of intermediate shaft for automobile gearbox produced by our company, as shown in Figure 1 The front end side wall of intermediate shaft 200 is provided with a steel ball hole 201, which is used for cooperation with gear teeth during subsequent assembly, and plays a limiting role. At present, after the workpiece production is completed, different tools need to be used to detect the position and depth of the steel ball hole, which leads to that workers need to detect a product twice in the actual quality inspection process, the operation is more complex, the work efficiency is low, and the workers have heavy workload.

[0004] Based on this, our company designs a kind of steel ball hole position and depth comprehensive gauge, which can detect the position and depth of the steel ball hole quickly in the process of simulating assembly, effectively simplifies the operation process, reduces the workload of workers and improves the work efficiency.

[0005] The utility model provides steel ball hole position and depth comprehensive gauge, can solve the technical problem that different tools need to be used to detect the position and depth of the steel ball hole in the prior art, which leads to low detection efficiency and heavy workload.

[0006] The application provides the following technical scheme:

[0007] The steel ball hole position and depth comprehensive gauge comprises a gauge body, an assembly hole for cooperation with a workpiece is arranged on the gauge body, a position detection assembly and a dial indicator for detecting the depth of the steel ball hole are arranged on one side of the assembly hole, the position detection assembly comprises a positioning pin slidingly arranged on the gauge body, a first reset elastic member is sleeved on the positioning pin, one end of the positioning pin extends to the inner wall of the assembly hole, and the other end of the positioning pin extends out of the gauge body to the outside; a shifting block is arranged between the positioning pin and the detection rod of the dial indicator, one end of the shifting block is in contact with the positioning pin, and the other end of the shifting block is in contact with the detection rod, and the positioning pin is used to drive the shifting block to move and then feed the movement distance to the dial indicator.

[0008] Beneficial effects:

[0009] 1. By setting the detection body and the assembly hole on the detection body, when the steel ball hole on the workpiece needs to be detected, the workpiece is assembled into the assembly hole, which can simulate assembly and limit positioning of the workpiece, facilitating the position and depth detection of the steel ball hole.

[0010] 2. By setting the positioning pin, when the workpiece is inserted into the assembly hole, the positioning pin is pressed. If the positioning pin can be inserted into the steel ball hole of the workpiece, it indicates that the position of the steel ball hole is correct, and the position detection of the steel ball hole can be completed at this time. Since the push block is provided between the positioning pin and the detection rod of the dial gauge, and one end of the push block is in contact with the positioning pin and the other end is in contact with the detection rod, when the positioning pin moves, the moving distance is first fed back to the push block, and then the moving distance is fed back to the dial gauge through the push block, so that the depth data of the steel ball hole is obtained while measuring the position of the steel ball hole, and the position and depth of the hole are detected at the same time by using one detection tool.

[0011] In summary, the comprehensive detection tool designed in the application can quickly identify the position of the steel ball hole and measure the depth of the steel ball hole, simplifying the detection process, reducing the workload of workers, and improving the work efficiency.
