Compared with the production line setting in the prior art, it has a higher degree of integration, can effectively save the space occupied by equipment, reduce production costs, and improve production rhythm.

[0033] Specifically, refer to Figure 1 and Figure 4 As shown, the silo 1 includes a top plate 11 and a bottom plate 12 that are relatively arranged, and the bottom plate 12 and the top plate 11 both extend along a first direction; the silo 1 also includes side plates 13, and the side plates 13 are located at both ends of the top plate 11 and are used to connect the top plate 11 and the bottom plate 12 to form a frame structure; the clamping assembly 3, the variable pitch assembly 2 and the workpiece 6 to be processed are all located in the silo 1.

[0034] Specifically, refer to Figure 2 and Figure 5 As shown, the variable distance assembly 2 includes a light rod 21, a distance block 22, a distance variable piece and a distance variable driving member; the light rod 21 extends along the first direction, and a plurality of the distance blocks 22 are sleeved on the outside of the light rod 21 and arranged along the first direction, each of the distance blocks 22 is used to fix a group of workpieces 6, and the distance variable piece and the distance variable driving member are used to control the spacing of the distance blocks 22 arranged on the light rod 21.

[0035] Next, in some embodiments, the pitch-changing driving member is configured as a pitch-changing cylinder 25, and the pitch-changing cylinder 25 is connected to the distance block 22 and drives it to move along the polished rod 21. The pitch-changing piece extends along the first direction, and a waist-shaped groove 24 is provided inside the pitch-changing piece, and the length direction of the waist-shaped groove 24 is the first direction; the waist-shaped groove 24 is configured as a through groove, and a positioning pin is provided on the surface of the distance block 22, which can be penetrated in the waist-shaped groove 24 and slidably connected therewith, and the pitch-changing control is realized by the relative position of the positioning pin in the waist-shaped groove 24, and the distance block 22 is limited.

[0036] It should be noted that in the existing production equipment, equal-length dividing pieces are used to achieve equal-distance torque change, but due to the processing process setting or workpiece size limitation, it is necessary to achieve unequal distance change between adjacent workpieces 6; accordingly, referring to Figure 5 and Figure 6 As shown, in a preferred embodiment of the utility model, the distance variable piece includes a first distance variable piece 2301 and a second distance variable piece 2302 with different extension lengths to achieve unequal distance variation; the distance block 22 includes a first distance block 2201 and a second distance block 2202, a group of the distance blocks 22 arranged at both ends of the light rod 21 is set as the first distance block 2201, and the distance block located between the two groups of the first distance blocks 2201 in the arrangement direction is set as the second distance block 2202.

[0037] Continue, refer to Figure 5 and Figure 6 As shown, the distance blocks 22 are arranged along the first direction. In the first direction, every two adjacent distance blocks 22 form a group. One first distance variable piece 2301 is connected between the two distance blocks 22 in each group. Each distance block 22 is connected to only one group of the first distance variable pieces 2301. In the first direction, except for the first distance block 2201, every two adjacent second distance blocks 2202 form a group.

Preferably, two second distance variable pieces 2302 are connected between the two second distance blocks 2202 in each group, and the two second distance variable pieces 2302 are arranged opposite to each other.

[0038] Next, in a preferred embodiment of the present invention, the extension length of the waist-shaped groove 24 of the first variable distance piece 2301 is greater than the extension length of the waist-shaped groove 24 of the second variable distance piece 2302, thereby widening the range of the variable distance adjustment of the distance block 22 in the first direction.

The two ends of the spring 35 are respectively connected to the distance block 22 and the pressure block 34, and the deformation direction of the spring 35 is perpendicular to the first direction and parallel to the direction in which the top plate 11 and the bottom plate 12 are arranged opposite to each other. When force is applied to the pressure block 34, the spring 35 is deformed and compressed by force.

[0041] Continue, refer to Figure 4 As shown, the roller 33 is fixed to the side of the pressing block 34 away from the spring 35, one side surface of the pressing plate in the thickness direction abuts against the outer periphery of the roller 33, and the other side surface in the thickness direction is connected to the clamping drive.
