As shown in fig. 1 to 5, an embodiment of the present invention provides a flatness adjustment mechanism 100, and the flatness adjustment mechanism 100 includes: the clamping device comprises two clamping pieces 10 and at least two pairs of adjusting assemblies 20 which are oppositely arranged, specifically, a first adjusting assembly 201 in each pair of adjusting assemblies 20 is arranged on one clamping piece 10 in the two clamping pieces 10, a second adjusting assembly 202 in each pair of adjusting assemblies 20 is arranged on the other clamping piece 10 in the two clamping pieces 10, the first adjusting assembly 201 and the second adjusting assembly 202 are oppositely arranged and used for clamping a product (not shown in the figure), each adjusting assembly 20 comprises a bolt 21 and an adjusting piece 22, the bolt 21 is connected with the corresponding clamping piece 10, and the adjusting piece 22 is used for adjusting the distance of the bolt 21 extending out of the corresponding clamping piece 10.

According to the flatness adjusting mechanism 100 of the embodiment of the utility model, the adjusting part 22 of the first adjusting component 201 is used for adjusting the distance that the corresponding bolt 21 extends to the corresponding clamping part 10, and the adjusting part 22 of the second adjusting component 202 is used for adjusting the distance that the corresponding bolt 21 extends to the corresponding other clamping part 10, that is, the distance that two adjusting components 20 extend to the corresponding clamping parts 10 and the distance between each pair of adjusting components 20 are respectively adjusted, so as to meet the requirement of adjusting the flatness of a product. The flatness adjusting mechanism can accurately adjust the distance between the bolt 21 and the clamping piece 10 through the adjusting piece 22, further adjust the distance between the bolts 21, avoid multiple times of measurement and adjustment, reduce the operation time of the flatness adjusting mechanism 100 and improve the working efficiency of the flatness adjusting mechanism.

It should be understood that each pair of adjusting assemblies 20 can adjust the distance between each pair of adjusting assemblies and the corresponding clamping member 10 according to the shape of the product, so as to adapt to the flatness adjustment of the product with different bending degrees.

In some embodiments of the utility model, the adjuster 22 is clamped between the nut 211 of the bolt 21 and the clamp 10. The adjustment member 22 may be provided at one side of the bolt 21, and the adjustment member 22 may also be arranged around the circumference of the bolt 21. Specifically, the adjusting member 22 includes a connecting block 221 and an adjusting block 222, the adjusting block 222 is formed with a plurality of steps 2221, the height direction of the steps 2221 is parallel to the length direction of the bolt 21, and the connecting block 221 selectively cooperates with one of the steps 2221 to adjust the height of the bolt 21. The screw 212 of the bolt 21 is inserted into the adjusting member 22 and then connected to the clamping member 10, and when the height of the adjusting member 22 is changed, the position of the bolt 21 relative to the clamping member 10 is also changed, for example, when the connecting block 221 moves from the low step 2221 to the high step 2221, the bolt 21 moves from the position close to the clamping member 10 to the direction away from the clamping member 10, that is, the portion of the bolt 21 protruding from the clamping member 10 is lengthened; after the connecting block 221 moves from the high step 2221 to the low step 2221, the bolt 21 moves from a position away from the clamping member 10 to a direction close to the clamping member 10, i.e. the portion of the bolt 21 protruding from the clamping member 10 becomes shorter.

As shown in fig. 3 to 5, when the connection block 221 is engaged with the different steps 2221 of the adjustment block 22, the length of the bolt 21 extending out of the clamp 10 is different. Specifically, when the connection block 221 is engaged with the highest step 2221 (the adjustment assembly 20 is in the first state, as shown in fig. 3), the length of the adjustment assembly 20 is longest, that is, the length of the bolt 21 extending out of the clamping member 10 is longest; when the connecting block 221 is engaged with the second highest step 2221 (the adjusting assembly is in the second state, as shown in fig. 4), the length of the adjusting assembly 20 is slightly shorter than that in the first state; connecting block 221 engages third height step 2221 (adjustment assembly is in the third state, as shown in fig. 5), and the length of adjustment assembly 20 is slightly shorter than the second state; the length of the adjustment assembly 20 is shortest when the connection block 221 is mated with the shortest step 2221.

It should be understood that the length of the bolt 21 is long enough that the bolt 21 and the clamping member 10 can always be connected when the connecting block 221 is engaged with any one of the steps 2221 of the adjusting block 222. Meanwhile, when the connection block 221 is matched with any step 2221 of the adjustment block 222, the distance that the bolt 21 extends out of the clamping member 10 is greater than the distance that the step 2221 extends out of the clamping member 10.

The bolt 21 may be inserted into the connecting block 221 and then connected to the clamping member 10. Specifically, each pair of adjusting assemblies 20 includes a bolt 21, each pair of adjusting members 22 includes two adjusting blocks 222 and a connecting block 221, which are oppositely disposed, the step 2221 of each corresponding level of the two adjusting blocks 222 can form a plane, both ends of the connecting block 221 are disposed on top of the step 2221 of the same level of the two adjusting blocks 222, and the bolt 21 extends into the connecting block 221 from one end of the connecting block 221, which is far away from the corresponding clamping member 10, extends into a space between the two adjusting blocks 222 from one end of the connecting block 221, which is close to the corresponding clamping member 10, and finally extends into a threaded hole of the clamping member 10, so as to achieve connection with the clamping member 10.

In addition, in order to maintain the positions of the two adjusting blocks 222 unchanged and ensure the reliability of the adjusting assembly 20, the two adjusting blocks 222 can be connected through a fixing block, and the fixing block is arranged at a position which does not affect the connection of the bolt 21 and the clamping member 10.
