Preferably, the horizontal mounting assembly 13 is movably connected to the carrier assembly 11. Through the movable setting of horizontal installation component 13 for horizontal installation component 13 can drive horizontal reference component 12 and remove, so that horizontal reference component 12 removes the calibration, increases the convenience of calibration.

Specifically, the first bearing frame 111 is a frame structure, and is disposed in a vertical state. The first sliding member 112 is a slide rail, and is laid on a frame at the upper end of the first bearing frame 111.

Specifically, the second carriage assembly 21 includes a second carriage (not shown) and a second slider 211. The structure and operation principle of the second sliding member 211 and the second carriage are the same as those of the first sliding member 111 and the first carriage, and are not described herein again. In a specific application, the second bearing frame is arranged along the arrangement direction of at least two workpieces. The parallelism mounting-assembly 23 in this embodiment is a slider, which fits into the second slide 211. The parallelism mounting-assembly 23 is slidably connected to the second slider 211. The parallelism reference assembly 22 is a rectangular plate, the middle part of the parallelism reference assembly is rotatably connected to the surface of the parallelism mounting assembly 23, and two opposite ends of the parallelism mounting assembly 23 are respectively exposed on the parallelism mounting assembly 23. In the present embodiment, the surface of the parallelism mount member 23 is processed to be flat, so that the parallelism mount member 23 is flat, and when the parallelism mount member 23 is slidably attached to the first slider 112, the surface of the parallelism mount member 23 is in a horizontal state, so that when the parallelism reference member 22 is mounted on the surface of the parallelism mount member 23, the parallelism mount member 23 is in a horizontal state.
Preferably, the parallelism calibration mechanism 2 further comprises a fixing assembly 24. The fixed assembly 24 is removably connected to the parallelism reference assembly 22. The fixing member 24 is used for fixing the parallelism reference member 22 after the movement.

Specifically, the fixing assembly 24 includes a fixing block 241 and a second fixing screw 242. The fixing block 241 is disposed on the second carriage, and the second fixing screw 242 is screwed with the parallelism reference assembly 22 after passing through the fixing block 241.
Referring back to fig. 1 and 2, further, the parallelism calibration process in this embodiment is as follows: the level meter is first placed on the parallelism referencing member 22, and when the level meter is displayed as being horizontal, the surface parallelism referencing member 22 is in a horizontal state. The level gauge is then removed and a height detector is placed on the parallelism reference assembly 22, for example, with a vertical scale. At this time, the height detecting apparatus is close to the side of the loading plate 200, and then the second slider 231 is moved, so that the height detecting apparatus moves along the side of the loading plate 200 to detect the height of the loading plate 200 close to the two clamping mechanisms 100 respectively, thereby obtaining the height difference of the two clamping mechanisms 100 loaded on the loading plate 200, and then the loading plate 200 is adjusted to eliminate the height difference, thereby conveniently and accurately completing the calibration of the parallelism. In another embodiment, the height of the clamping plates 101 of the two clamping mechanisms 100 can be directly detected by a height detector, and the parallelism calibration can be completed based on the height difference of the two clamping plates 101. In other embodiments, if the workpiece is another mechanism, the height detector is used to attach to a part of the product supported by the other mechanism, and after the height detection is completed, the parallelism is adjusted by the height difference. After parallelism calibration is complete, the second set screw 242 is rotated so that the parallelism reference assembly 22 and the parallelism mounting assembly 23 are fixed and no longer move.
