DETAILED DESCRIPTION

[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] See also Figure 1-2 , the utility model provides a two-way three-dimensional variable pitch module, including a base 1;

[0027] An x-direction pitch-changing module 2 includes an x-frame 20 horizontally arranged at the upper and lower ends of the base 1, an x-roller 21 rotatably arranged in the inner cavity of the x-frame 20, an x-guide rail 22 fixedly arranged on the top of the x-frame 20, a plurality of x-slides 23 movably arranged on the x-guide rail 22, and an x-pitch-changing rod 24 connecting the x-slides 23 corresponding to the two sides thereof;

[0028] A y-direction pitch-changing module 3, comprising a y-frame 30 horizontally disposed at the left and right ends of the base 1, a y roller 31 rotatably disposed within the inner cavity of the y-frame 30, a y guide rail 32 fixedly disposed on the top of the y-frame 30, a plurality of y slides 33 movably disposed on the y guide rail 32, and a y pitch-changing rod 34 connecting the corresponding y slides 33 horizontally on both sides;

[0029] A first drive device 4 is installed on one side of the machine base 1 and is connected to the X-direction pitch-changing module 2 on one side via a first transmission device 40 , and the X-direction pitch-changing modules 2 on the upper and lower sides are connected via a second transmission device 41 ;

[0030] A second drive device 5 is installed on one side of the machine base 1 and is connected to the Y-direction variable pitch module 3 on one side through a third transmission device 50. The Y-direction variable pitch modules 3 on the left and right sides are connected through a fourth transmission device 51.

[0031] A linear bearing 6 is provided with a first through-hole 60 and a second through-hole 61 which are staggered. The first through-hole 60 is passed through by the x-pitch change rod 24, and the second through-hole 61 is passed through by the y-pitch change rod 34. The linear bearing 6 is provided at a transverse intersection position between all the x-pitch change rods 24 and the y-pitch change rods 34.

[0032] In the above structure, the first drive device is connected to the x-direction pitch changing modules arranged on both sides through the first transmission device and the second transmission device, and the second drive device is connected to the y-direction pitch changing modules arranged on both sides through the third transmission device and the fourth transmission device. The x-direction pitch changing modules or y-direction pitch changing modules arranged correspondingly on both sides are controlled by a single drive device, which not only controls the movement speed of the x-direction pitch changing modules or y-direction pitch changing modules used in conjunction with both sides to be consistent, but also reduces the number of drive devices required to be used, saving costs. At the same time, the combination of the x-direction pitch changing module and the y-direction pitch changing module allows the linear bearing to move to any position on the x and y axes, increases the moving direction of the overall bidirectional three-dimensional pitch changing module, increases the use occasions of the bidirectional three-dimensional pitch changing module, and improves the use range of the bidirectional three-dimensional pitch changing module.

[0033] Specifically, an x ​​slider 25 for use with the x guide rail 22 is provided at the bottom of the x slide 23, and a y slider 35 for use with the y guide rail 32 is provided at the bottom of the y slide 33. The cooperation between the guide rail and the slider can play a guiding role, and the cooperation between the two has the advantages of high precision and high stability.

[0034] Specifically, a gap is provided at the connection between one end of the x-pitch changing rod 24 and the x-slide 23 for the movement of the x-pitch changing rod 24, and a gap is provided at the connection between one end of the y-pitch changing rod 34 and the y-slide 33 for the movement of the y-pitch changing rod 34. The main purpose of the gap between the x-pitch changing rod and the x-slide on one side and the gap between the y-pitch changing rod and the y-slide on one side is to reserve some moving space for the pitch changing rod. The main reason is that the x-direction pitch changing modules corresponding to both sides and the y-direction pitch changing modules corresponding to both sides cannot be set absolutely parallel, so the reserved gap allows the pitch changing rod to have space for fine-tuning to ensure that the pitch changing module can operate normally.

[0035] Specifically, the first driving device 4 is a driving motor. Using a driving motor as a driving device has the advantages of high efficiency and energy saving, high reliability, and small space occupation.

[0036] Specifically, the second driving device 5 is a driving motor. Using a driving motor as a driving device has the advantages of high efficiency and energy saving, high reliability, and small space occupation.

[0037] Specifically, the first transmission device 40 and the second transmission device 41 are a synchronous belt and a synchronous pulley. Using a synchronous pulley and a synchronous belt as a transmission element has the advantages of accurate and stable transmission, high efficiency and energy saving.

[0038] Specifically, the third transmission device 50 and the fourth transmission device 51 are synchronous belts and synchronous pulleys. Using synchronous pulleys and synchronous belts as transmission elements has the advantages of accurate and stable transmission, high efficiency and energy saving.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
