Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 14, the sliding table locking mechanisms of the present invention are symmetrically disposed on two sides of the sliding rail 2 along the sliding direction of the sliding block 1, and the sliding table locking mechanisms on the two sides have the same structure.

The sliding table locking mechanism on each side comprises a front end base 3, a front end upper pressing plate 4, a locking connecting piece end 7, a locking connecting piece 6, a rear end base 11, a rear end base large guide column 13, a rear end base small guide column 17 and a rear end base pressing plate 14, wherein the front end base 4 and the rear end base 11 are arranged in the front and back direction along the sliding direction of the sliding block 1 on the sliding rail 2 (namely the length direction of the sliding rail 2), the lower end of the front end base 4 is fixedly connected onto the sliding rail 2, and the upper end of the front end base 4 is fixedly connected with the front end upper pressing plate 4 through a front end fixing screw 5; one end of a stop connecting piece end 7 is positioned below the front end upper pressing plate 4 and is rotationally connected with the front end base 3, the other end of the stop connecting piece end is connected with one end of a stop connecting piece 6, and the stop connecting piece end 7 is limited in the vertical direction through the front end upper pressing plate 4. One end of the end head 7 of the stop connecting piece is provided with a hole, the horizontal projection of the other end is U-shaped, and bolt holes are formed in two sides of the U-shaped opening; the front end base 3 is columnar, and is penetrated through an opening at one end of the end head 7 of the locking connecting piece and is in interference fit with the opening. One end of the stop connecting piece 6 is inserted through the U-shaped opening and is connected with a stop connecting piece end head 7 through a stop connecting piece locking bolt 9 and a stop connecting piece locking nut 8 which are inserted into the bolt holes, and a loosening washer 10 is arranged between the stop connecting piece locking nut 8 and the stop connecting piece end head 7.

The lower end of the rear base 11 is fixedly connected to the slide rail 2 by a rear base locking screw 12, the lower ends of the rear base large guide column 13 and the rear base small guide column 17 are fixedly connected to the upper end of the rear base 11, and the upper ends of the rear base large guide column 13 and the rear base small guide column 17 are fixedly connected to the two ends of the rear base pressing plate 14 by a large guide column locking screw 15 and a small guide column locking screw 16, respectively. The other end of the locking connecting piece 6 passes through the space between the rear end base large guide post 13 and the rear end base small guide post 17 and is positioned below the rear end base pressing plate 14, and the vertical direction limitation is realized through the rear end base pressing plate 14.

The stop connecting piece 6 is arc-shaped and protrudes towards the sliding direction of the sliding block 1. The stop connecting piece 6 is made of a multi-layer composite material and can be a composite material spring piece, the composite material spring piece is made of a stainless steel spring piece sprayed with a layer of wear-resistant engineering plastic, and the wear-resistant engineering plastic is sprayed on one surface, which is in contact with the sliding block 1. In this embodiment, a gap for the other end of the locking connector 6 to pass through is left between the large rear base guide post 13 and the small rear base guide post 17, and two sides of the other end of the locking connector 6 are respectively abutted to the large rear base guide post 13 and the small rear base guide post 17.

The working principle of the invention is as follows:

when the sliding block 1 does unpowered inertial linear motion relative to the sliding rail 2, the sliding block 1 has motion kinetic energy, the left side and the right side of the sliding direction of the sliding block 1 are respectively contacted with the convex parts of the stopping connecting pieces 6 in the stopping mechanisms at the two sides, the curvature of the convex parts of the stopping connecting pieces 6 is gradually increased within a period of motion time after the starting through the sliding friction mechanism of the sliding block 1 and the stopping connecting pieces 6, the motion kinetic energy of the sliding block 1 is gradually converted into the stored elastic potential energy of the stopping connecting pieces 6, the inertial kinetic energy of the sliding block 1 is gradually dissipated, finally, the motion of the sliding block 1 is stopped, and the curvature of the convex. The working principle of the sliding table stop mechanisms on the two sides is the same.

When the stopping state of the sliding block 1 relative to the sliding rail 2 is manually released, the elastic potential energy of the stopping connecting piece 6 is released in the process that the continuous curvature of the convex part of the stopping connecting piece 6 is reduced; through the sliding friction mechanism of the sliding block 1 and the stopping connecting piece 6, two sides of the sliding block 1 are respectively contacted with the protruding parts of the stopping connecting piece 6, the elastic potential energy of the stopping connecting piece 6 is converted into the motion kinetic energy of the sliding block 1 within a period of motion time after the start, and the stopping connecting piece 6 plays a role in assisting in the process of continuously accelerating the motion of the sliding block 1.

The sliding table stop mechanism has the characteristic of overload protection when moving in the length direction relative to the sliding rail 2. When the energy is too large, the movement of the sliding block 1 relative to the sliding rail 2 can pass through the stop mechanism.
