Problems solved by technology

[0002] The clamping device for stopwatch verification used in the past is only suitable for stopwatches with a circular structure. However, most of the stopwatches that need to be verified have irregular shapes and various structural shapes. Moreover, the positions of the switch buttons are also very different. It has brought a lot of trouble to the stopwatch verification work, and also greatly affected the quality and efficiency of the verification. For this reason, our company has specially developed a clamping device for stopwatch verification that can adapt to various structural shapes and button positions.

Embodiment 1

[0027] Such as Figures 1 to 7 As shown, a clamping device for stopwatch verification includes a box bottom plate 1, the box bottom plate 1 is fixedly connected to the box edge vertical plate 9 around the box bottom plate 1, and the upper ends of the four box edge vertical plates 9 are fixedly connected to the box top plate 13;

[0028] A clamping unit is arranged on the bottom plate 1 of the box, and the structure of the clamping unit is as follows: the clamping unit includes a horizontal disk B5, and four straight lines are evenly laid on the disk B5 with the center of the circle as the starting point and the horizontal angle is evenly divided by bolts. motor;

[0029] The stator 3 of the linear motor is fixed on the disc B5 by bolts, and the guide rail 2 is fixed on the stator 3 along its axial direction, and the guide rail 2 is slidingly connected with the chute provided at the lower end of the mover 36 of the linear motor. There is an air gap between the sub 36 and the s...

Embodiment 2

[0041] The specific structure of the clamping unit in the second embodiment is consistent with the specific structure of the clamping unit in the first embodiment. The second embodiment includes a PLC controller 10, a display screen 11, and a stopwatch calibration instrument 12. In order to clearly show the second embodiment Different from Embodiment 1, the present application provides a partial view, that is, a view that does not include the PLC controller 10, the display screen 11, and the stopwatch calibration instrument 12, such as Figures 8 to 9 As shown, the difference between the second embodiment and the first embodiment is that there are five clamping units in the second embodiment, and they are numbered from left to right as clamping unit I, clamping unit II, and clamping unit III , clamping unit IV, clamping unit V;

[0042] In addition, five servo motors 7 are fixed on the bottom plate 1 of the box, and the five servo motors 7 correspond to the five clamping units...

Abstract

The invention discloses a clamping device for stopwatch verification. In the clamping device for stopwatch verification, a clamping unit comprises a disc B, four linear motors are uniformly distributed on the disc B, and sliding seats are arranged on the four linear motors separately; vertical rods are arranged at the top ends of the sliding seats and penetrate upwards through strip-shaped groovesformed in a disc C and then are connected with shaft shoulders, rectangular sleeves are arranged on the vertical rods located above the shaft shoulders and are capable of horizontally rotating on thevertical rods, and a pressure sensor A is fixedly installed on the vertical surface of each rectangular sleeve; the lower end of the disc C is fixedly connected with the disc B through a supporting element, a small hole is formed in the center of the disc C, a contact of a microswitch penetrates upwards through the small hole, and the top of the contact is higher than the upper surface of the disc C in a normal state. The clamping device for stopwatch verification is applicable to clamping verification for stopwatches in the shape similar to a triangular stopwatch, a circular stopwatch, an elliptical stopwatch, a polygonal stopwatch and the like, and is particularly applicable to clamping verification for asymmetric shapes and special switch button positions.

Description

technical field [0001] The invention belongs to the technical field of measurement verification auxiliary devices, in particular to a clamping device for stopwatch verification. Background technique [0002] The clamping device for stopwatch verification used in the past is only suitable for stopwatches with a circular structure. However, most of the stopwatches that need to be verified have irregular shapes and various structural shapes. Moreover, the positions of the switch buttons are also very different. It has brought a lot of trouble to the stopwatch verification work, and has greatly affected the quality and efficiency of the verification. Therefore, our company has specially developed a clamping device for stopwatch verification that can adapt to various structural shapes and button positions. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides a clamping device for stopwatch testing. [0004] Techni...
