[0027] Reference Figure 1-4 This utility model provides a clamping base for testing precision hardware parts, including a base plate 1. The upper end of the base plate 1 is fixedly connected to two left and right distributed first support plates 2. The interior of each of the two first support plates 2 is slidably connected to a second bearing cylinder 20. The interior of each of the two second bearing cylinders 20 is rotatably connected to a rotating shaft 19. The ends of the two rotating shafts 19 that are close to each other are fixedly connected to clamping plates 3. An angle adjustment mechanism and a position adjustment mechanism are installed on the circumferential surface of each of the two rotating shafts 19. The angle adjustment mechanism is used to control the rotation of the two clamping plates 3, and the position adjustment mechanism is used to control the movement of the two clamping plates 3 in order to clamp and fix a precision hardware part.

[0028] The angle adjustment mechanism includes an electric telescopic rod 7, a support frame 6, racks 5, and long gears 18. The electric telescopic rod 7 is fixedly connected to the upper end of the base plate 1 via a fixed seat. The support frame 6 is slidably connected to the upper end of the base plate 1. The output end of the electric telescopic rod 7 is fixedly connected to the support frame 6. Two racks 5 are fixedly connected to the upper end of the support frame 6. Long gears 18 are fixedly connected to the circumferential surfaces of both rotating shafts 19. The long gears 18 are located between the first bearing sleeve 11 and the second bearing sleeve 20, and the two long gears 18 mesh with the two racks 5 respectively. During operation, the entire device... The clamping base can be used in conjunction with testing equipment. In specific use, the position adjustment mechanism first controls the movement of the two clamping plates 3 to clamp and fix a precision hardware part. Then, the electric telescopic rod 7 is controlled to retract, driving the support frame 6 to move forward. The support frame 6 drives the rack 5 to move forward, which in turn drives the long gear 18 to rotate. As the long gear 18 rotates, it drives the rotating shaft 19 to rotate, which in turn drives the clamping plate 3 to rotate, thereby driving the precision hardware part to rotate. This facilitates subsequent observation and testing of multiple different surfaces of the precision hardware part.

[0029] Both clamping plates 3 have a protruding edge 4 fixedly connected to their bottom ends, and the protruding edge 4 and the clamping plate 3 are an integral structure. During operation, the protruding edge 4 facilitates the support of precision hardware parts, making the precision hardware parts more stably positioned between the two clamping plates 3.

[0030] Two second support plates 12 are fixedly connected to the upper end of the base plate 1. The angle adjustment mechanism is located between the two second support plates 12. First bearing cylinders 11 are slidably connected inside each of the two second support plates 12. Two rotating shafts 19 extend into the two first bearing cylinders 11 and are rotatably connected to them. During operation, the cooperation between the first bearing cylinders 11 and the second support plates 12 allows the rotating shafts 19 to rotate more smoothly.

[0031] The position adjustment mechanism includes a movable plate 10, a motor 8, a threaded rod 14, and a connecting rod 9. Threaded rods 14 are rotatably connected to the interior of both first support plates 2. The threads on the surfaces of the two threaded rods 14 are in opposite directions. Movable plates 10 are threadedly connected to the circumferential surfaces of both threaded rods 14. The two movable plates 10 are located on the circumferential surfaces of the two second bearing cylinders 20 and are fixedly connected to the two second bearing cylinders 20 respectively. The two threaded rods 14 are fixedly connected to each other through the connecting rod 9, and the connecting rod 9 is rotatably connected to the first support plate 2. The upper end of the base plate 1 is fixedly connected to the motor 8, and the output shaft end of the motor 8 is fixedly connected to the threaded rod 14 located on the left end. During operation, the motor 8 first drives the left threaded rod 14 to rotate, and with the cooperation of the connecting rod 9, it simultaneously drives the right threaded rod 14 to rotate. As the two threaded rods 14 rotate, the two moving plates 10 can drive the two second bearing cylinders 20 and the rotating shaft 19 to move along the two first support plates 2 in a direction that is closer to or farther away from each other, thereby driving the two clamping plates 3 to move so as to complete the clamping and fixing of the precision hardware parts.

[0032] Two sliding strips 16, distributed front to back, are fixedly connected to the circumferential surfaces of both the first bearing sleeve 11 and the second bearing sleeve 20. Sliding holes 17 are provided on the left end faces of both the second support plate 12 and the first support plate 2, allowing the two sliding strips 16 to pass through. The sliding strips 16 are located within the sliding holes 17 and are slidably connected to them. During operation, the cooperation of the sliding strips 16 and the sliding holes 17 allows the first bearing sleeve 11 and the second bearing sleeve 20 to move more stably along the first support plate 2 and the second support plate 12, respectively. The rotating shaft 19 can also rotate stably, and the rotation of the rotating shaft 19 does not easily affect the first bearing sleeve 11 and the second bearing sleeve 20.

[0033] Guide rods 13 are fixedly connected to both ends of the two first support plates 2. Sliding seats 15 are slidably connected to the circumferential surfaces of the guide rods 13, and the sliding seats 15 are fixedly installed on the upper end of the support frame 6. During operation, the guide rods 13 and sliding seats 15 cooperate to guide the support frame 6, enabling the support frame 6 to move stably.

[0034] The distance between the rotating shaft 19 and the front and rear faces of the clamping plate 3 is the same, and the distance between the front face of the clamping plate 3 and the rotating shaft 19 is less than the distance between the protruding edge 4 and the connecting rod 9. During operation, this allows the rotating shaft 19 to drive the clamping plate 3 to rotate normally without being obstructed by the connecting rod 9.

[0035] Working principle:

[0036] In use, a rectangular precision hardware component is placed between two clamping plates 3 and rests on two protruding edges 4. Then, the motor 8 is controlled to operate. The motor 8 first drives the left threaded rod 14 to rotate, and with the cooperation of the connecting rod 9, it simultaneously drives the right threaded rod 14 to rotate. As the two threaded rods 14 rotate, the two moving plates 10 drive the two second bearing cylinders 20 and the rotating shaft 19 to move along the two first support plates 2 towards each other, thereby driving the two clamping plates 3 to move closer together, thus completing the clamping and fixing of the precision hardware component. Then, the entire component can be... The clamping base, which is composed of the body equipment, is connected to the appearance inspection equipment. The appearance inspection equipment is used to inspect the appearance of the precision hardware, or the user can observe and inspect the appearance of the precision hardware himself. Then, the electric telescopic rod 7 is controlled to retract, which drives the support frame 6 to move forward. The support frame 6 drives the rack 5 to move forward, which in turn drives the long gear 18 to rotate. As the long gear 18 rotates, it drives the rotating shaft 19 to rotate, which drives the clamping plate 3 to rotate, thereby driving the precision hardware to rotate. In this way, multiple different sides of the precision hardware can be observed and inspected.
