Description

Technical Field

[0001] The utility model relates to the field of linear modules, in particular to a belt anti-loosening automatic adjustment structure of a linear module. Background Art

[0002] Belt-type linear modules are widely used in the automation industry due to their high speed and quiet operation. Their main transmission mechanism is a cloth-wrapped belt. Due to the inherent ductility of the cloth-wrapped belt 2, even if it is tensioned during assembly, it will become loose after long-term load use, resulting in inaccurate positioning accuracy or equipment failure. The main solution currently is for users to regularly tighten the hexagon socket screw 3 to drive the movable buckle 8 to adjust the belt tension.

[0003] Existing belt linear modules usually require users to regularly tighten the hexagonal screws (adjustment is required every two months). This maintenance work is easy to forget, and the torque control during this maintenance action is not accurate and uniform, which in turn affects the service life of the belt linear module.

[0004] In addition, linear modules are often assembled inside automated equipment. The hexagonal screw 3 for belt tensioning is on the side of the slide. The load on the slide often blocks the hexagonal screw, making it difficult for the user to turn the hexagonal screw for belt adjustment. This also increases the difficulty of maintenance work. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a belt anti-loosening automatic adjustment structure for a linear module.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0007] A linear module belt anti-loosening automatic adjustment structure includes a slide, a cloth-wrapped belt, and a hexagon socket screw. The toothed buckle at the end of the cloth-wrapped belt is assembled on the slide via a movable buckle and a fixed buckle; the fixed buckle is fixed to the slide via a screw; the movable buckle is slidably assembled in the slide and assembled via the hexagon socket screw in conjunction with a corrugated spring piece and a flat washer.

[0008] Furthermore, the slide is provided with an adjustment slot, the fixed buckle is fixedly mounted at the end of the adjustment slot, and protrusions are provided on both sides of the movable buckle, which is slidably assembled in the adjustment slot;

[0009] Furthermore, the adjustment chute is provided with an assembly beam, and the hexagon socket screw passes through the assembly beam and is inserted into the movable buckle; the corrugated spring piece and the flat washer are sleeved on the stud between the movable buckle and the assembly beam;

[0010] Furthermore, the corrugated springs are assembled in multiple groups simultaneously;

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The utility model adopts the method of using built-in corrugated spring pieces and flat washers on the belt structure of the linear module to automatically solve the problem of loosening of the belt caused by long-term use; it avoids the need for users to tighten the adjustment screws regularly, solves the situation where users forget or have no operating space to tighten the adjustment screws, and achieves the purpose of automatic adjustment to prevent the belt from loosening.

[0014] Figure 2 It is a schematic diagram of the structure of the utility model after partial concealment;

[0015] Figure 3 This is a sectional view of the present invention. DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] refer to Figure 1-3 As shown, a belt anti-loosening automatic adjustment structure for a linear module includes a slide 1, a cloth-wrapped belt 2, and a hexagon socket screw 3. The toothed buckle at the end of the cloth-wrapped belt 2 is assembled on the slide 1 via a movable buckle 6 and a fixed buckle 7; the fixed buckle 7 is fixed to the slide 1 via a screw; the movable buckle 6 is slidably assembled in the slide 1 and assembled with a corrugated spring piece 4 and a flat washer 5 via the hexagon socket screw 3;

[0018] Furthermore, the slide 1 is provided with an adjustment slot 11, the fixed buckle 7 is fixedly mounted at the end of the adjustment slot 11, and the movable buckle 6 is provided with protrusions on both sides and is slidably assembled in the adjustment slot 11;

[0019] Furthermore, the adjustment chute 11 is provided with an assembly beam, and the hexagon socket screw 3 passes through the assembly beam and is inserted into the movable buckle 6; the corrugated spring piece 4 and the flat washer 5 are sleeved on the stud between the movable buckle 6 and the assembly beam;

[0020] In this embodiment, during assembly, the belt is tightened by twisting the hexagonal screw 3 to squeeze the corrugated spring piece 4 and the flat washer 5, pushing the movable buckle 6 to move. At this time, the corrugated spring piece 4 stores elastic potential energy due to the squeezing; after the user uses it for a long time, the cloth belt 2 becomes loose, and the corrugated spring piece 4 releases the elastic potential energy and offsets the looseness of the cloth belt 2, so that the movable buckle 6 remains in its original position.

[0021] Furthermore, the corrugated springs 4 are assembled in multiple groups simultaneously;

[0022] In this embodiment, multiple groups of multiple corrugated springs 4 can add up the elastic force to ensure that the released elastic potential energy is sufficient to compensate for the loss caused by aging of the belt.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] By adopting the utility model, four supporting parts are locally added to the sliding frame to avoid adding a layer of smooth material to the entire sliding frame surface. In addition, the embedded strong magnets allow the steel belt to pass through the sliding frame in a free bending state without the steel belt deflecting or vibrating, thereby ensuring the sealing of the module and preventing the steel belt from breaking or deforming. The overall structure is simple and the cost is controllable.

[0025] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described, or replace them with similar methods, without departing from the scope defined by the spirit of the present invention.
