[0029] The present invention will be further described in detail below with reference to specific embodiments:

[0030] like Figure 1 As shown, the bidirectional pitch adjustment mechanism includes a power component 2, a set of parallel pitch components 1, a set of parallel first linear guides 3, and a set of parallel second linear guides 4. The length between the two endpoints of the two pitch components 1 can be changed by extension or retraction.

[0031] The length direction of the power assembly 2 is parallel to the first linear guide 3, and the extension direction of the second linear guide 4 is parallel to the pitch conversion assembly 1. The first linear guide 3 on one side is integrally mounted on the second linear guide 4 via the mounting plate 5. Thus, a set of pitch conversion assemblies 1 and a set of first linear guides 3 form a quadrilateral adjustment plane.

[0032] See attached document Figure 2 The two sets of pitch conversion components 1 are connected to the same transmission component 21 of the power component 2 on the same side. The two ends of the pitch conversion components 1 are respectively installed on the first linear guides 3 on both sides and can move along the first linear guides 3.

[0033] Specifically, as shown in the attached document Figure 2 Or attached Figure 3As shown, the variable distance assembly 1 includes a pair of mounting seats 13, two pairs of linear bearings 12 and a connecting rod 11. The connecting rod 12 is a rigid member (such as a copper rod, iron rod or metal alloy rod) and is provided with a bottom plate 6 at the bottom of the mounting plate 5. The telescopic cylinder 7 is fixedly installed on the bottom plate 6. The mounting plate 5 is connected to the telescopic end of the telescopic cylinder 7 through the transition connecting block 8. The telescopic cylinder 7 is operated in a telescopic manner to drive the mounting plate 5 and the first linear guide 3 on one side of the mounting plate 5 and the same side end of the two variable distance assemblies 1 to move as a whole.

[0034] The linear bearing 12 corresponds to the connecting rod one by one and is coaxially installed together. One end of the connecting rod 11 is fixedly connected to the mounting seat 13 through the linear bearing 12, and the two pairs of linear bearings 12 are not at the same end. One end of the connecting rod 11 is fixed, and the other end penetrates the mounting seat 13 and can move along the penetrating hole.

[0035] Referring to the accompanying drawings Figure 3 Combined with the accompanying drawings Figure 4 As shown, two states of the connecting rod 11 before and after the change are schematically provided when the width is adjusted to be reduced. The two first linear guides 3 on the two sides move towards each other, and the connecting rod 11 moves in the penetrating hole to adapt to the change of the distance. Similarly, when the width is adjusted to be increased, the two first linear guides 3 on the two sides move away from each other, and the length of the connecting rod 11 gradually decreases to adapt to the change of the distance. Therefore, referring to the accompanying drawings Figure 3 Combined with the accompanying drawings, the two variable distance assemblies 1 are synchronously telescoped, so that the second linear guide 4 drives the first linear guide 3 on one side to move close to or away from the first linear guide 3 on the other side, thereby realizing the variable distance in the Y-axis direction.

[0036] Referring to the accompanying drawings Figure 2 The mounting seats 13 on the two sides are respectively installed on the first linear guide 3 at the bottom through the moving seat plate 14. The mounting seat 13 on one side of the power assembly 2 is assembled on the transmission member 21 through the connecting sleeve plate 9 and the reverse nut 10.

[0037] The power assembly 2 includes a driving motor 22. The driving motor 22 is a servo motor, and the transmission member 21 is installed on the output end of the driving motor 22. The driving motor 22 drives the connecting sleeve plate 9 to move through the transmission member 21, thereby driving the two variable distance assemblies 1 to move away from each other or move towards each other along the first linear guide 3, thereby realizing the variable distance in the X-axis direction.

[0038] Among them, the first linear guide 3 and the second linear guide 4 can adopt one of the linear guide rail, the linear sliding table and the servo motor transmission mechanism. As shown in the embodiment Figure 2 In the embodiment, the first linear guide 3 and the second linear guide 4 both adopt the linear guide rail.

[0039] In an embodiment or other implementation, referring to the accompanying drawings Figure 1The transmission member 21 adopts a grinding screw rod, the thread grooves on the grinding screw rod are opposite in direction, a reverse nut 10 is arranged on the grinding screw rod to limit the moving end points of the connecting sleeve plate 9, and when the driving motor 22 operates, the transmission member 21 drives the two sides of the variable-distance assembly 1 to be able to move synchronously in opposite directions or in the same direction.
