[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 3 , in the embodiment of the present invention, an anti-collision device for a machine tool slide includes an anti-collision buffer assembly 1 composed of an L-shaped seat 101, a screw hole 102, a rubber buffer block 103, a fastening bolt 104, a mounting hole 105, and a mounting bolt 106. The screw hole 102 is opened on one end face of the vertical part of the L-shaped seat 101. The rubber buffer block 103 is connected and fixed to the L-shaped seat 101 through the fastening bolt 104 threaded into the screw hole 102. The mounting hole 105 is opened at the top of the horizontal part of the L-shaped seat 101 and penetrates to the bottom of the L-shaped seat 101. The mounting bolt 106 passes through the mounting hole 105 and is connected to the mounting screw hole on the bed of the machine tool slide to fix the L-shaped seat 101. A regulating support assembly 2 is arranged below the L-shaped seat 101, and the regulating support assembly 2 is used to adjust the mounting height of the rubber buffer block 103;

[0024] The regulating support assembly 2 includes a triangular base 201, an inclined chute 202, and a straight groove through hole 204;

[0025] The inclined chute 202 is opened on the inclined upper surface of the triangular base 201. The lower surface of the L-shaped seat 101 is inclined and fits against the bottom inner wall of the inclined chute 202. The overall height of the L-shaped seat 101 and the rubber buffer block 103 is adjusted by sliding the L-shaped seat 101 along the inclined inner wall of the inclined chute 202;

[0026] The straight groove through hole 204 is opened at the bottom inner wall of the inclined chute 202 and penetrates to the bottom of the triangular base 201. The mounting bolt 106 is connected to the mounting screw hole on the bed by passing through the straight groove through hole 204.

[0027] In this embodiment: when this device is in use, the lower surface of the triangular base 201 can be made to fit against the surface of the bed of the machine tool slide, and the mounting hole 105 is aligned with the mounting screw hole on the bed. Then, the mounting bolt 106 passes through the mounting hole 105 and the straight groove through hole 204 in sequence and is threadedly connected and tightened with the mounting screw hole, so as to fix the device. Then, the rubber buffer block 103 can be installed by threading the fastening bolt 104 into the screw hole 102 (it should be noted that: a side-inverted "T" hole for the fastening bolt 104 to penetrate is formed in the middle of the rubber buffer block 103. This structure is a prior art structure, so it is not elaborated here);

[0028] The slide plate of the rubber buffer block 103 faces the machine tool slide. When the slide plate moves and contacts the rubber buffer block 103, the rubber buffer block 103 can play a role in restricting its sliding and buffering;

[0029] During the installation of the device, the installation height of the rubber buffer block 103 can be adjusted according to the horizontal height of the slide plate. It only needs to move the L-shaped seat 101 along the trajectory of the inclined chute 202 before installing the installation bolt 106 to achieve height adjustment. Through this operation, it can adapt to machine tool slides of different models and specifications, further improving the versatility of the device.

[0030] Please refer specifically to Figures 1 to 3 , a plurality of positioning card slots 203 are provided at the bottom of the inner wall of the tipping chute 202, and the plurality of positioning card slots 203 are evenly distributed along the inclined trajectory of the tipping chute 202;

[0031] A plurality of positioning strips 108 are fixed on the lower surface of the L-shaped seat 101, and the plurality of positioning strips 108 are evenly distributed along the inclined trajectory of the lower surface of the L-shaped seat 101, and the distribution pitch of the positioning strips 108 matches the distribution pitch of the positioning card slots 203;

[0032] The L-shaped seat 101 is horizontally limited by engaging the positioning strip 108 with the positioning card slot 203;

[0033] On both sides of the inclined upper surface of the triangular base 201, limiting guide rails 205 are symmetrically and fixedly connected. On both sides of the transverse part of the L-shaped seat 101, inclined guide blocks 107 are symmetrically fixed. The inclined guide blocks 107 are slidably connected to the inner side of the limiting guide rails 205 to limit and guide the movement of the L-shaped seat 101;

[0034] The distance between the upper and lower surfaces of the inner wall of the limiting guide rail 205 is greater than the thickness of the inclined guide block 107;

[0035] The inclination angles of the lower surface of the L-shaped seat 101, the tipping chute 202, the limiting guide rail 205, and the inclined guide block 107 match each other.

[0036] In this embodiment: when it is necessary to adjust the height of the L-shaped seat 101, only need to lift the L-shaped seat 101 upward so that the positioning strip 108 moves upward and separates from the positioning card slot 203. At this time, the tipping guide block 107 fits on the upper surface of the inner wall of the limiting guide rail 205. Then, the L-shaped seat 101 can be tilted and moved. After adjusting to the appropriate height, the L-shaped seat 101 can be vertically lowered so that the positioning strip 108 is engaged with the positioning card slot 203 at this position. At this time, the inclined guide block 107 fits on the lower surface of the inner wall of the limiting guide rail 205. Finally, it can be installed through the installation bolt 106;

[0037] The horizontal limit between the L-shaped base 101 and the triangular base 201 can be achieved by the snap connection between the positioning strip 108 and the positioning slot 203. Through the cooperation between the limit guide rail 205 and the inclined guide block 107, the complete separation of the L-shaped base 101 from the triangular base 201 can be avoided, keeping the device in an integral and non-dispersed state, thus facilitating the installation operation (it should be additionally noted that when the L-shaped base 101 is at different heights, mounting bolts 106 with different lengths can be configured. If the mounting screw holes on the bed body completely penetrate the bottom of the bed body, enabling the mounting bolts 106 to penetrate below the bed body, only one longest mounting bolt 106 needs to be configured).

[0038] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
