Description

Technical Field

[0001] This disclosure relates to the field of component dimension inspection technology, and more specifically, to an auxiliary assembly inspection device. Background Technology

[0002] See Figure 1 As shown, a certain type of dial mechanism, when the dial is rotated, outputs a counting pulse via a photoelectric encoder, providing a high / low angle tracking signal to the computer. During use, the dial should rotate smoothly without jamming, remaining in a balanced state at any position, and should not exhibit any self-rotation. During production, to meet technical specifications (hole edge distance, rotational smoothness), the hole edge distance needs to be measured with a ruler after assembly to ensure the dimensions are within the tolerance range.

[0025] The preferred embodiments of this disclosure will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this disclosure can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this disclosure.

[0026] See Figure 1 As shown, an auxiliary assembly inspection device for inspecting the hole edge distance A of the dial mechanism 6 includes a base 1, a mechanism assembly fixing device 2, a caliper 3, a caliper driving device 4, and a caliper fixing device 5.

[0027] The base 1 can be a plate or a frame structure, used to place on the workbench, on which other structures of the auxiliary assembly and testing device are installed.

[0028] The mechanism assembly and fixing device 2 is installed on the base 1 for assembling and fixing the dial mechanism 6. The dial mechanism 6 can be assembled on the mechanism assembly and fixing device, and after simple fixing, the hole edge distance A is measured and then finally fixed. Alternatively, the dial mechanism 6 can be fixed on the mechanism assembly and fixing device 2 after assembly and then the hole edge distance A is measured.

[0029] The caliper 3 is mounted on the base 1 and includes a first clamping foot 31 and a second clamping foot 32. It is used to detect the hole edge distance A on the dial mechanism 6 by clamping the first clamping foot 31 and the second clamping foot 32 at the hole position and the edge position.

[0030] The caliper drive device 4 is mounted on the base 1 and is used to drive the first caliper foot 31 of the caliper 3 to contact or move away from the edge position of the dial mechanism 6.

[0031] The caliper fixing device 5 is installed on the base and can fix the second caliper foot 32 of the caliper 3 at the hole position in the dial mechanism 6.

[0032] This disclosure uses a mechanism assembly and fixing device 2 to assemble a dial mechanism 6. After the dial mechanism 6 is simply assembled and fixed, the hole edge distance is checked by calipers 3. If the hole edge distance meets the requirements, the final assembly and reinforcement are carried out. The caliper fixing device 5 can fix the second caliper foot 32 of the caliper 3 to the hole position in the dial mechanism 6. The caliper driving device 4 can drive the first caliper foot 31 of the caliper 3 to contact or move away from the edge position of the dial mechanism 6. The markings on the caliper can be checked, which is convenient and quick to detect.

[0033] A pin 61 is installed in the hole position on the dial mechanism 6, and the second locking foot 32 is fixed to the side of the pin 61. This allows the second locking foot 32 to be directly locked onto the side of the pin 61 without the need for manual alignment of the hole position.

[0034] See Figure 3 As shown, the caliper fixing device 5 includes a stop 51 mounted on the base 1. The second caliper foot 32 can move on the stop 51 to facilitate moving the second caliper foot 32 to the hole position. The stop 51 is also equipped with a fixing device 52 for fixing the second caliper foot 32. The fixing device 52 can be a set screw, a pressure block, or a clamp, etc.

[0035] The stop block 51 is provided with a guide rail 53, and the guide rail 53 has stop portions 54 on both sides. The second locking foot 32 is installed in the guide rail 53 and can move in the guide rail 53. The stop portions 54 on both sides are used to limit the movement direction of the second locking foot 32. When the fixing device 52 is a set screw, the set screw passes through the threaded hole on the stop portion 54 and stops on the second locking foot 32. When the second locking foot 32 moves to the hole position, tightening the set screw can fix the position of the second locking foot 32. When it is necessary to move the second locking foot 32, simply loosen the set screw.

[0036] See Figure 3 , Figure 4 As shown, the caliper driving device 4 includes a driving device 41 and a telescopic device 42. The telescopic device 42 has a fixed part 421 and a sliding part 422. Both the driving device 41 and the fixed part 421 are mounted on the base 1. The driving device 41 can drive the sliding part 422 to move on the fixed part 421. The sliding part 422 is connected to the first caliper foot 31. The driving device 41 can drive the sliding part 22 to move on the fixed part 421, thereby driving the first caliper foot 31 to contact or move away from the edge position of the dial mechanism 6. The caliper driving device 4 can be a linear motor.

[0037] In one embodiment, the driving device 41 is a motor, and the telescopic device 42 is a lead screw and a lead screw nut. The rotating shaft of the motor is connected to one end of the lead screw, and the lead screw nut is sleeved on the lead screw and fixedly connected to the first locking foot 31. A set of guide rails can also be provided on the base 1 to guide the fixing part 421 and prevent the lead screw from being subjected to large lateral forces.

[0038] The motor is mounted on the base 1 via a front bearing seat 43, and the other end of the lead screw is mounted on the base via a rear bearing seat 44, facilitating the installation of the motor and lead screw. The motor is connected to a controller 7, which is mounted on the upper part of the mechanism assembly and fixing device 2 for easy operation. The second locking foot 31 has a claw portion 311 and a ruler 312. The ruler 312 has size markings for easy reading; these markings can be directly read dimensions or positioning dimensions (red lines). The second locking foot 32 has a guide groove, and the ruler 312 passes through the guide groove. The direction of the guide groove is the same as the movement direction of the guide rail 53 and the telescopic device 42.
