[0050] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings contained in each term.

[0051] Figure 2 It is a structural schematic diagram of a bushing pressing depth detection device of the utility model. Figure 3 The utility model is a schematic diagram of the installation of the bushing pressing depth detection device and the bushing. Figure 4 It is a schematic diagram of the structure of the touch gauge in the bushing press-in depth detection device of the utility model. Figure 5 The utility model is a schematic diagram of the installation of the touch gauge in the bushing pressing depth detection device.

[0052] like Figures 2 to 5 As shown, the utility model discloses a bushing press-in depth detection device, which includes a detection sleeve 100, a detection assembly 200 and a dial indicator 300. A through mounting through hole 110 is provided at the center of the detection sleeve 100, and the detection assembly 200 is slidably connected in the mounting through hole 110. The dial indicator 300 is installed at the first open end 111 of the mounting through hole 110, and the detection end of the dial indicator 300 extends into the mounting through hole 110 and contacts the upper end of the detection assembly 200.

[0053] The second open end 112 of the mounting through hole 110 is used to mount the bushing 400 , so that the lower end surface of the detection assembly 200 fits with the end surface of the bushing 400 , and the lower end surface of the detection sleeve 100 fits with the end surface of the rigid body 410 outside the bushing 400 .

[0054] Preferably, the detection assembly 200 includes a detection block 210 and a detection shaft 220 connected to each other, and the width of the detection shaft 220 is smaller than the width of the detection block 210. Here, the detection shaft 220 and the detection block 210 are preferably cylindrical structures.

[0055] The detection shaft 220 is used to lead out the end surface of the bushing 400, and the detection sleeve 100 is used to lead out the end surface of the rigid body 410.

[0056] Further preferably, the mounting through hole 110 includes a first through hole 120 , a second through hole 130 and a third through hole 140 which are interconnected from top to bottom, and the detection shaft 220 is passed through the second through hole 130 into the third through hole 140 , so that the detection block 210 is located in the third through hole 140 .

[0057] Preferably, an elastic component 230 is sleeved on the detection shaft 220, and one end of the elastic component 230 abuts against the upper step surface of the second through hole 130, and the other end abuts against the detection block 210, so that the detection shaft 220 moves up and down along the second through hole 130. The elastic component 230 here can preferably be a spring.

[0058] The detection shaft 220, the detection block 210 and the detection sleeve 100 slide up and down, and an elastic connection is achieved by adding a small elastic spring with appropriate elastic force in the middle.

[0059] More preferably, the bushing pressing depth detection device further includes a touch gauge 500. After the detection is completed, if the dial gauge 300 is taken out, the touch gauge 500 is replaced by the dial gauge 300 and installed in the first open end 111 of the installation through hole 110, that is, inserted above the detection sleeve 100 and in contact with the upper end of the detection component 200.

[0060] In particular, the upper end surface of the touch gauge 500 is configured as a stepped surface structure. The stepped surface structure may preferably include a first stepped surface 510 and a second stepped surface 520 connected to each other, and the height of the first stepped surface 510 is higher than the height of the second stepped surface 520.

[0061] Preferably, the height difference between the first step surface 510 and the second step surface 520 is a tolerance value of the pressing depth of the bushing 400 .

[0062] According to the above structural description, when the bushing insertion depth detection device of the utility model is used, the lower end face of the detection sleeve 100 is attached to the end face of the rigid body 410, and the lower end face of the detection shaft 220 is attached to the end face of the bushing 400. There is a fixed drop between the upper end face of the detection sleeve 100 and the upper end face of the detection shaft 220. When the dial indicator 300 is inserted on the upper part, the reading can be accurately read. At this time, the quantitative detection function of the bushing insertion depth detection device is realized, such as Figure 2 shown.

[0063] If the dial indicator 300 is removed and the touch gauge 500 is inserted above, it is only necessary to check whether the upper end surface of the detection sleeve 100 falls between the first step surface 510 and the second step surface 520 of the touch gauge 500. The height distance between the first step surface 510 and the second step surface 520 corresponds to the size of the tolerance band of the pressing depth.

[0064] If it falls between the first step surface 510 and the second step surface 520, the test result is qualified. If it is higher than the first step surface 510 or lower than the second step surface 520, the test result is unqualified. This is the qualitative detection function of the bushing press depth detection device, such as Figure 5 shown.

[0065] The bushing pressing depth detection device of the utility model can flexibly adapt to the detection requirements of qualitative detection and quantitative detection, and can avoid large differences in detection results between different operators.

[0066] The bushing pressing depth detection device can quickly detect the bushing pressing depth, can perform both qualitative and quantitative detection, and can solve the problem of large differences in detection results between different operators.

[0067] In summary, the bushing pressing depth detection device of the utility model can quickly detect the bushing pressing depth, can perform both qualitative and quantitative detection, and can solve the problem of large differences in detection results between different operators.

[0068] The bushing pressing depth detection device is suitable for situations where the pressing depth of various bushings needs to be detected after being pressed into a rigid body. It can flexibly adapt to the detection needs of qualitative detection and quantitative detection, and can avoid large differences in detection results between different operators. It can be applied not only to the automotive industry, but also to other industrial fields where bushing connection designs are used.
