[0030] The preferred embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present disclosure can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present disclosure.

[0031] See Figure 2As shown, an automatic auxiliary assembly detection device is used to detect the hole margin A of the dial mechanism 6, including a base 1, a mechanism assembly fixture 2, a caliper 3, a caliper driving device 4 and a caliper fixture 5:

[0032] The base 1 can be a plate or a frame structure, which is used to be placed on a workbench, and other structures in the automatic auxiliary assembly detection device are installed thereon.

[0033] The mechanism assembly fixture 2 is installed on the base 1 and is used to assemble and fix the thumbwheel mechanism 6. The thumbwheel mechanism 6 can be assembled on the mechanism assembly fixture, and the hole margin A can be measured after simple fixation before final fixation. Alternatively, the thumbwheel mechanism 6 can be assembled and placed on the mechanism assembly fixture 2 and fixed before the hole margin A is measured.

[0034] The caliper 3 is mounted on the base 1 and includes a second detection portion 31 and a first detection portion 32 , and is used to detect the hole margin A on the dial mechanism 6 by clamping the second detection portion 31 and the first detection portion 32 at the hole position and the edge position;

[0035] The caliper driving device 4 is mounted on the base 1 and is used to drive the second detection portion 31 of the caliper 3 to contact or leave the edge position of the dial mechanism 6;

[0036] The caliper fixing device 5 is installed on the base, and can fix the first detection portion 32 of the caliper 3 at the hole position in the dial mechanism 6 .

[0037] The position detection device 7 is installed at the position of the second detection part 31 of the caliper, and is used to detect the moving position of the second detection part 31 and identify whether the second detection part 31 is in contact with the edge or away from the edge.

[0038] The control device is connected to the caliper driving device 4 and the position detecting device 7 , and is used to receive the position of the second detecting portion 31 and control the caliper driving device 4 .

[0039] When the device disclosed herein needs to be inspected, the caliper fixing device 5 fixes the first detection part 32 at the hole position of the dial mechanism 6, and the control device controls the caliper driving device 4 to drive the second detection part 31 to move to the edge position of the dial mechanism 6. The position detection device 7 recognizes that the second detection part 31 has moved into position, and then reads the size on the caliper. After the identification is completed, the control device controls the caliper driving device 4 to drive the second detection part 31 to leave the edge position of the dial mechanism 6. After the position detection device 7 recognizes that the second detection part 31 is away from the edge position, the control device controls the second detection part 31 to stop.

[0040] In one embodiment, see Figures 2 to 4The position detection device 7 includes a first position sensor 71 and a second position sensor 72. The first position sensor 71 and the second position sensor 72 are both installed on the second position detection part 31 of the caliper. The second position sensor 72 is located outside the first position sensor 71. An outer baffle 8 is also installed on the base 1. The second detection part can move inward to the edge position where the first position sensor is aligned with the dial mechanism, and the second detection part can move outward to the position where the second position sensor 72 is aligned with the outer baffle 8. The first position sensor 71 and the second position sensor 72 are both connected to the control device.

[0041] There are many existing technologies for circuit design of control devices; see Figure 5 、 Figure 6 As shown, the present disclosure provides a circuit arrangement method. After the first position sensor 71 and the second position sensor 72 detect a contact signal, they will both turn off the caliper drive device 4. In addition, a power button, a control switch button and an indicator light can be set to facilitate key operation.

[0042] A pin 61 is installed in the hole position on the dial mechanism 6, and the first detection part 32 is fixed to the side of the pin 61. It is convenient for the first detection part 32 to be directly mounted on the side of the pin 61 without manually aligning the edge line of the hole position.

[0043] See Figure 3 As shown, the caliper fixing device 5 includes a stopper 51 mounted on the base 1. The first detection portion 32 can move on the stopper 51, which facilitates moving the first detection portion 32 to the hole position. The stopper 51 is also mounted with a fixing device 52 for fixing the first detection portion 32. The fixing device 52 can be a set screw, a pressure block, a clamp, etc.

[0044] A guide rail 53 is provided on the stop block 51, and stop parts 54 are provided on both sides of the guide rail 53. The first detection part 32 is installed in the guide rail 53 and can move in the guide rail 53. The first detection part 32 and the guide rail 53 can be an integrated part or two parts fixed to each other. The stop parts 54 on both sides are used to limit the moving direction of the first detection part 32; when the fixing device 52 is a set screw, the set screw passes through the threaded hole on the stop part 54 and stops on the first detection part 32. When the first detection part 32 moves to the hole position, the set screw is tightened to fix the position of the first detection part 32. When the first detection part 32 needs to be moved, the set screw only needs to be loosened.

[0045] See Figure 3 、 Figure 4As shown, the caliper drive device 4 includes a drive device 41 and a telescopic device 42. The telescopic device 42 has a fixed portion 421 and a sliding portion 422. The drive device 41 and the fixed portion 421 are both mounted on the base 1. The drive device 41 can drive the sliding portion 422 to move on the fixed portion 421. The sliding portion 422 is connected to the second detection portion 31. The drive device 41 can drive the sliding portion 22 to move on the fixed portion 421, thereby driving the second detection portion 31 to contact or leave the edge position of the dial mechanism 6. The caliper drive device 4 can use a linear motor.

[0046] In one embodiment, the driving device 41 is a motor, and the telescopic device 42 is a screw and a nut. The rotating shaft of the motor is connected to one end of the screw, and the nut is sleeved on the screw, and the nut is fixedly connected to the second detection portion 31. A set of guide rails can also be provided on the base 1 to guide the fixed portion 421 so that the screw is not subjected to large lateral forces.

[0047] The motor is mounted on the base 1 through the front bearing seat 43, and the other end of the screw is mounted on the base through the rear bearing seat 44, which is convenient for installing the motor and the screw. The motor is connected to the control unit 7, and the control unit 7 is mounted on the upper part of the mechanism assembly fixture 2, which is convenient for personnel to operate. The first detection part 31 has a claw part 311 and a ruler rod 312. The ruler rod 312 has a size mark for easy reading. The size mark can be a directly read size or a positioning size red line. The first detection part 32 has a guide groove, and the ruler rod 312 is inserted into the guide groove. The direction of the guide groove is the same as the moving direction of the guide rail 53 and the telescopic device 42.
