Description

Technical Field

[0001] The utility model relates to the technical field of wide rail safety clamps, in particular to a bidirectional linkage mechanism of wide rail safety clamps. Background Art

[0002] Wide-track safety clamps are a common type of clamp, which is mainly composed of components such as driving parts and pliers. The driving parts are also called two-way linkage mechanisms. When working, the two-way linkage mechanism drives the two slides to move at the same time, and further drives the pliers and other clamping parts to move, so as to realize the clamping operation. The two-way linkage mechanism generally drives the two slides on it to move in opposite directions at the same time to achieve the effect of loosening and clamping.

[0003] Since the two-way linkage mechanism is provided with a guide rail, the corresponding slider slides in the slide groove in the guide rail. The conventional two-way linkage mechanism cannot add lubricating fluid to the slide groove for lubrication operation. With long-term use, the slider and the groove wall will be worn due to lack of lubrication. After wear, the stability of the slider during movement will be affected, causing inconvenience to the user. In view of this, we propose a two-way linkage mechanism for wide-track safety clamps.

[0029] Specifically, a forward screw 20 is fixedly installed at the end of the output shaft of the servo motor 2, and a reverse screw 21 is fixedly installed at the end of the forward screw 20. The forward screw 20 and the reverse screw 21 are both threadedly connected with a slider 3. The slider 3 is located in the slide groove 10 and is slidably connected to the slide groove 10, so that the forward screw 20 and the reverse screw 21 are rotated to drive the slider 3 to move, thereby realizing a two-way linkage operation.

[0030] Specifically, the slider 3 is provided with a plurality of flow holes 30 arranged along the horizontal direction, and the flow holes 30 are used for the circulation operation of the lubricating fluid. A slide seat 31 is fixedly installed on the top of the slider 3, so that when the slider 3 slides in the slide groove 10, the lubricating fluid in the slide groove 10 can flow along the flow holes 30.

[0031] In this embodiment, a discharge pipe 12 connected to the slide groove 10 is fixedly mounted on the end plate of the guide rail 1 , and a threaded cover 13 is threadedly connected to the discharge pipe 12 to facilitate the sealing operation of the discharge pipe 12 .

[0032] Specifically, a sealing ring 121 is sleeved on the discharge pipe 12, and the threaded cover 13 presses the sealing ring 121 against the guide rail 1 to achieve a sealing and protective effect; a hexagonal protrusion 131 is fixedly installed on the end of the threaded cover 13, and the hexagonal protrusion 131 is used in conjunction with an external wrench.

[0033] Furthermore, two left and right supporting seats 32 symmetrical to each other are fixedly mounted on the upper surface of the sliding seat 31 , and the supporting seats 32 are used for the installation operation of the clamp.

[0034] In addition, a shielding guide plate 4 is provided above the guide rail 1 , and the shielding guide plate 4 covers the top of the slide groove 10 . The shielding guide plate 4 is used to shield the slide groove 10 to prevent debris from falling into the slide groove 10 .
