In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention.

[0022] Please see Figure 1 and Figure 2 This utility model provides a device for detecting the position of a connecting rod screw hole, comprising a mounting base 1, a fixing component 2, and a detection component 3. The mounting base 1 has a first mounting area and a second mounting area, which are adjacent to each other. The fixing component 2 is located in the first mounting area and has a fixing position for fixing the connecting rod. The detection component 3 is located in the second mounting area and has a detector 31 and a mating part, with the mating part facing the fixing position.

[0023] The mating part has a retracted position and a detection position. When the connecting rod is placed in the fixed position, the end of the connecting rod presses against the mating part, causing the mating part to move outward. The mating part is in the detection position, driving the detector 31 to perform detection. When the mating part moves under force, it drives the detector 31 to move (or is compressed), thus enabling the detector 31 to monitor. When the connecting rod disengages from the fixed position, the mating part is in the retracted position. When the mating part retracts, the detector 31 is in a zero-state. This application enables rapid measurement of the connecting rod screw hole position.

[0024] Please see Figure 3 Specifically, in an optional embodiment of this application, the mounting base 1 is provided with a sliding component 4 and a reset component 5. The sliding component 4 is arranged along a first direction, and the docking part is arranged on the sliding component 4. The detector 31 abuts against the sliding component 4. The reset component 5 is connected to the sliding component 4 and the mounting base 1 respectively, and is used to reset the sliding component 4. When the connecting rod is taken out from the fixed position, the reset component 5 pulls the sliding component 4, thereby pulling the docking part from the detection position to the retracted position, and automatically resets the docking part.

When the first detection block 32, the second detection block 33 and the third detection block 34 are subjected to pressure, they can all drive the sliding component 4 to squeeze the detector 31, thereby obtaining the detection result.

[0029] Specifically, in an optional embodiment of this application, at least two first fixing rods are provided on the first fixing block 21, and the at least two first fixing rods are spaced apart along the first direction.

The first fixing rods are used to fix the screw holes of the connecting rod. The connecting rod is provided with two screw holes respectively fitted onto the two first fixing rods. When the connecting rod is fitted onto the first fixing rods, the end of the connecting rod close to the first detection block 32 presses against the first detection block 32, thereby pushing the sliding component 4 to move. The sliding component 4 presses against the detector 31, thereby realizing the inspection of the distance between the end of the connecting rod and the screw hole.

[0031] Specifically, in one optional embodiment of this application, at least two second fixing rods are provided on the second fixing block 22, and the at least two second fixing rods are spaced apart along a second direction, which is perpendicular to the first direction.
