Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rails, in particular to a linear guide rail locking device. Background Art

[0002] Linear guides are also called linear rails, slides, linear guides, and linear slides. Linear guides are used in high-precision or high-speed linear reciprocating motion situations, and can bear a certain torque, and can achieve high-precision linear motion under high load conditions.

[0003] The linear guide mainly consists of a guide rail and a slider. When the linear guide is transporting items, the slider on it needs to stay in the specified position from time to time to facilitate the staff to pick up and place the items transported by the linear guide.

[0004] Existing linear guide locking devices, such as the Chinese utility model with application number 202220214433.7, drive the extrusion top block to move through a screw drive assembly, thereby increasing the friction between the slider and the guide rail to achieve locking of the slider. However, the structure of the screw drive assembly is too complicated, which is not convenient for the maintenance of the slider and is not conducive to its production. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] The utility model will now be further described in conjunction with the accompanying drawings.

[0031] Embodiment 1

[0032] Combined with Figure 1-2 The slider 2 is slidably connected to the guide rail 1. Grooves 3 are provided on both sides of the front of the guide rail 1. The extending direction of the groove 3 is consistent with the direction of the guide rail 1. A connecting groove 4 is provided on the lower end surface of the slider 2. Balls 12 are rollingly connected at the left and right ends of the inner surface of the connecting groove 4 corresponding to the position of the groove 3. The ball 12 is rollingly connected to the groove 3.

[0033] When the slider 2 moves on the guide rail 1, the slider 2 is clamped on the guide rail 1 through the connecting groove 4, and the balls 12 on the inner surface of the connecting groove 4 roll in the grooves 3 on the front and back sides of the guide rail 1 to ensure the stability and smoothness of the movement of the slider 2 on the guide rail 1.

[0034] Combined with Figure 3-4 A brake pad 5 is slidably connected to the inner surface of the connecting groove 4 at a position corresponding to the groove 3. A driving component for driving the brake pad 5 to move synchronously is provided in the slider 2. The driving component includes a pneumatic element 6, a transmission plate 7 and a transmission rod 8. A cavity 9 is provided in the slider 2. A pneumatic element 6 is provided in the cavity 9. A transmission plate 7 is provided on the piston rod of the pneumatic element 6. The transmission plate 7 is symmetrically provided with inclined slots 10 in the front and rear. The left ends of the two slots are opposite to the right ends. The upper end of the transmission rod 8 is slidably connected to the slot 10, the transmission rod 8 is slidably connected to the slider 2, and the lower end of the transmission rod 8 is connected to the brake pad 5 through a connecting block 11.

[0035] When the position of the slider 5 on the guide rail 4 needs to be locked, the piston rod of the pneumatic element 9 extends out, driving the transmission plate 7 to move leftward. The transmission plate 7 moves leftward through the inclined slot 10, driving the transmission rod 8 whose upper end is slidably connected to the slot 10 to move relative to each other. The transmission rod 8 drives the brake pad 5 to move relative to each other through the connecting block 11. The brake pad 5 moves relative to each other and fits tightly with the groove 3 on the guide rail 1, thereby locking and positioning the position of the slider 2, making the locking speed of the slider 2 faster.

[0036] Embodiment 2

[0037] Combined with Figure 1 and 3 A guide assembly is provided in the cavity 9, and the guide assembly guides the movement direction of the transmission plate 7. The guide assembly includes a guide rod 13 and a spring 14. A guide rod 13 is provided on the end of the cavity 9 opposite to the pneumatic element 6. The guide rod 13 is slidably connected to the transmission plate 7. A spring 14 is provided between the transmission plate 7 and the cavity 9 outside the guide rod 13. A cover plate 15 is provided in the upper end of the cavity 9, and the cover plate 15 is connected to the cavity 9 by connecting screws.

[0038] On the basis of the first embodiment, when the transmission plate 7 moves, the guide rod 13 guides the movement direction of the transmission plate 7. When the piston rod of the pneumatic element 6 retracts, the transmission plate 7 can quickly return to the initial position under the action of the spring 14, so that the brake pad 5 can quickly return to the initial position. By removing the cover plate 15 at the upper end of the cavity 9, it is convenient to inspect and repair the drive assembly.

[0039] The utility model and its implementation are described, and such description is not restrictive.
