[0028] Reference Figures 1 to 3 The lightweight linear module of the utility model is implemented as follows:

[0029] A lightweight linear module includes a driving base 100 , a cover plate 200 , a driving slide 300 and a driving component 400 .

[0030] The cover plate 200 is fixedly arranged on the upper side of the driving base 100. The driving slide 300 is movably sleeved on the outer side of the cover plate 200, and the upper end of the driving slide 300 has a mounting plane in a planar shape. The mounting plane is arranged on the upper side of the cover plate 200. The lower end of the driving slide 300 has a connecting portion 310 arranged in pairs on the left and right. Both of the connecting portions 310 are arranged on the lower side of the cover plate 200 and are slidably connected to the driving base 100 along the front-back direction.

[0031] A clearance gap is provided between the two connecting parts 310. A plurality of support members 500 are provided between the cover plate 200 and the driving base 100. The plurality of support members 500 are arranged in a front-to-back direction. The upper and lower ends of the support members 500 are respectively fixedly connected to the cover plate 200 and the driving base 100. The support members 500 are aligned front-to-back with the clearance gap.

[0032] The driving member 400 is provided with a driving end which is transmission-connected with the driving slide 300 and enables the driving slide 300 to move in the front-rear direction relative to the driving base 100 .

[0033] In actual use, the driving member 400 drives the driving slide 300 to move forward and backward. The support member 500 can connect the cover plate 200 and the driving base 100 to support the cover plate 200, greatly reducing the installation span spacing of the cover plate 200, thereby reducing the strength requirement of the cover plate 200. The driving slide 300 is slidably connected to the driving base 100 through two connecting parts 310, and can avoid the support member 500 through the avoidance gap, thereby achieving lightweighting of the cover plate 200.

[0034] A linear slide 110 extending forward and backward is provided between the connecting portion 310 and the driving base 100, and the driving member 400 is provided between the two linear slides 110. The driving member 400 drives the driving slide 300 to move forward and backward in the middle, and the two linear slides 110 are respectively connected to the two connecting portions 310 of the driving slide 300, so that the driving slide 300 can be evenly stressed, and a deflection torque is not applied to the driving slide 300 during the driving process, resulting in a situation where the load of the linear slide 110 on one side is large, thereby improving the accuracy of the linear slide 110 and extending its service life.

[0035] In this embodiment, the driving base 100 includes: a base body 120 and an end plate 130. The number of the end plates 130 is two. The two end plates 130 are respectively arranged at the front and rear ends of the base body 120. The front and rear ends of the cover plate 200 are respectively fixedly connected to the two end plates 130.

[0036] The cross-section of the base body 120 is in a "U" shape. The base body 120 has a bottom plate and side plates provided on the left and right sides of the bottom plate. The end plate 130 is in a flat plate shape. The two end plates 130 are respectively arranged at the front and rear ends of the base body 120. The left and right ends of the end plate 130 are flush with the left and right ends of the base body 120, and the lower end of the end plate 130 is flush with the lower end of the base body 120, so that the base body 120 and the two end plates 130 form a groove structure extending in the front and rear directions.

[0037] The cover plate 200 is flush with the upper end of the end plate 130. There is a gap between the cover plate 200 and the upper ends of the left and right sides of the base body 120. The middle part of the driving slide 300 is movably arranged in the gap between the cover plate 200 and the base body 120.

[0038] In this embodiment, the cover plate 200 is in a flat plate shape. The middle part of the cover plate 200 is thicker, and the left and right ends are thinner. There are a plurality of weight-reducing cavities 210 penetrating through the front and rear directions on the inner side of the middle part of the cover plate 200. By arranging the plurality of weight-reducing cavities 210, a structure similar to a square tube can be formed, which can reduce the self-weight of the cover plate 200 while having little influence on the strength of the cover plate 200.

[0039] Both of the two linear slide rails 110 are arranged on the upper side of the bottom plate of the base body 120, and the two linear slide rails 110 are arranged between the side plates. The thickness of the bottom plate is greater than the thickness of the side plates. A plurality of clearance grooves penetrating through the front and rear directions are arranged on the inner side of the bottom plate. By arranging the clearance grooves, the self-weight of the bottom plate can be reduced, and the weight of the linear module can be further reduced.

[0040] In a further embodiment, both the cover plate 200 and the bottom plate of the driving base 100 have clearance holes 220 penetrating through the upper and lower directions. The clearance holes 220 communicate the outside with the space surrounded by the cover plate 200 and the driving base 100. It is preferred that the clearance holes 220 of the cover plate 200 and the bottom plate are aligned up and down. The clearance holes 220 are aligned with the support members 500 in the front and rear directions. The clearance holes 220 are arranged between adjacent support members 500.

[0043] The bottom plate is provided with a driving seat cover 160 and a driven seat cover 170. The driving shaft 140 is rotatably arranged in the driving seat cover 160, and the driving seat cover 160 is fixedly connected to the bottom plate. The driving unit 410 is fixedly installed at the lower end of the driving seat cover 160 and is drivingly connected to the driving shaft 140.

[0044] In order to facilitate the control of the conveying speed and accuracy, the driving unit 410 in this embodiment adopts a servo motor, and the driving unit 410 is connected to the driving shaft 140 through a reduction gearbox.

[0045] The driven shaft 150 is rotatably inserted into the driven seat sleeve 170, and the driven seat sleeve 170 is adjustably connected to the bottom plate in the front-to-back direction. The driven seat sleeve 170 has a strip groove extending front-to-back. The driven seat sleeve 170 is locked and connected to the bottom plate by a screw inserted into the strip groove. The bottom plate is threaded with a tightening bolt, and the tightening bolt extends in the front-to-back direction. The tightening bolt is arranged on the side of the driven seat sleeve 170 facing the driving seat sleeve 160 and abuts against the driven seat sleeve 170.

[0046] On a projection plane perpendicular to the front-to-back direction, the driving shaft 140 and the driven shaft 150 are centrally arranged on the driving base 100, and the driving belt 430 is wound around the two driving pulleys 420, so that the driving belt 430 is centrally arranged between the cover plate 200 and the driving base 100 in the left-right direction, and the supporting members 500 are all arranged in the area surrounded by the driving belt 430.

[0047] The first clamping plate 320 and the second clamping plate 330 are fixedly provided at the lower end of the driving slide 300.
