Description

Technical Field

[0002] A guide rail clamp is a brake used to clamp guide rails and position, fix, and prevent working parts from falling and vibrating. Guide rail clamps include manual and pneumatic drive types. Existing manual guide rail clamps are operated by pulling a handle during clamping operations. However, in actual operations, the pulling angle of the handle may be limited by the equipment mounting frame outside the guide rail, that is, the rotatable angle of the handle is small. At this time, the clamping activity range of the guide rail clamp is small, and it is easy for the guide rail clamp to fail to fully match the guide rail width. Based on this, a locking mechanism for a linear guide rail is provided. Utility Model Content

[0031] See also Figures 1 to 4In the embodiment of the utility model, a locking mechanism for a linear guide rail includes a base body 1 composed of a concave seat 101, a telescopic circular groove 102, and a through circular groove 103. The telescopic circular grooves 102 are symmetrically arranged on both sides of the outer wall of the concave seat 101. The through circular groove 103 is arranged inside the concave seat 101 and is connected with the two telescopic circular grooves 102. The telescopic circular grooves 102 and the through circular grooves 103 are provided with locking components 2.

[0033] The locking unit includes a clamping round block 201, a first threaded column 202, a second threaded column 203, a connecting column 205, and a handle 206;

[0034] The clamping round block 201 is symmetrically slidably connected to the inner side of the two telescopic circular grooves 102, the first threaded column 202 and the second threaded column 203 are symmetrically distributed on the inner side of the penetrating circular groove 103 and penetrate the two clamping round blocks 201, and the first threaded column 202 and the second threaded column 203 are respectively threadedly connected to the two clamping round blocks 201;

[0035] The connecting column 205 is fixed to one side of the first threaded column 202 and is located outside the concave seat 101 , and the handle 206 is fixed to one side of the connecting column 205 ;

[0036] The outer wall threads of the first threaded column 202 and the second threaded column 203 are in opposite directions, and the two clamping round blocks 201 are respectively formed with internal threaded holes matching the outer wall threads of the first threaded column 202 and the second threaded column 203;

[0037] The synchronous rotation of the first threaded column 202 and the second threaded column 203 can realize the synchronous and unidirectional movement of the two clamping round blocks 201, and the clamping of the two clamping round blocks 201 with the guide rail is realized by the mutual approach of the two clamping round blocks 201;

[0038] The adjustment unit includes a semicircular limiting ring block 204;

[0039] The two semicircular limiting ring blocks 204 are respectively fixed on the side where the first threaded column 202 and the second threaded column 203 are close to each other. The two semicircular limiting ring blocks 204 are distributed in an annular staggered manner along the circumferential direction, and the straight surfaces of the two semicircular limiting ring blocks 204 fit each other. The first threaded column 202 and the second threaded column 203 can realize synchronous rotation through the fit of the two semicircular limiting ring blocks 204, and can move in the horizontal direction at the same time. The first threaded column 202 and the second threaded column 203 can be brought close to each other to reduce the movable range of the two clamping round blocks 201, and the first threaded column 202 and the second threaded column 203 can be moved away from each other to increase the movable range of the two clamping round blocks 201.

[0040] The linkage assembly 3 includes a knob 301, a bidirectional threaded screw 302, a movable guide hole 303, and an internal thread 304;

[0041] The movable guide hole 303 passes through the other side of the second threaded column 203 from one side of the second threaded column 203 and extends through the inside of the first threaded column 202;

[0042] The bidirectional threaded screw 302 is fixed to one side of the knob 301, and the bidirectional threaded screw 302 passes through the second threaded column 203, the semicircular limiting ring block 204, and reaches the inside of the first threaded column 202 through the movable guide hole 303;

[0043] The internal threads 304 are integrally formed on the inner sides of the two semicircular limiting ring blocks 204, and the spiral directions of the internal threads 304 on the inner sides of the two semicircular limiting ring blocks 204 are in opposite states, and the two internal threads 304 are respectively connected to the two spiral grooves on the bidirectional threaded screw rod 302;

[0044] The two semicircular limiting ring blocks 204 can be moved closer to or farther away from each other by rotating the bidirectional threaded screw 302 .

[0045] In this embodiment: when the device is performing a locking operation, its operation mode is the same as that of a conventional manual guide rail clamp, and it only needs to rotate the handle 206, and the handle 206 drives the first threaded column 202 to rotate, and the first threaded column 202 can drive the second threaded column 203 to rotate through the cooperation of two semicircular limiting ring blocks 204, so that the two clamping round blocks 201 can be synchronously approached or separated, and then the clamping or releasing of the guide rail is realized;

[0046] When the handle 206 is limited in rotation angle, the handle 206 rotation angle cannot meet the two clamping round blocks 201 to be sufficiently close to each other, then the distance between the first threaded column 202 and the second threaded column 203 can be adjusted, and the operation steps are as follows:

[0047] Apply a horizontal thrust to the knob 301 to make it fit the outside of the concave seat 101, and then rotate the knob 301 synchronously, and the knob drives the bidirectional threaded screw 302 to rotate. Since the outer wall of the bidirectional threaded screw 302 has two mutually staggered spiral thread grooves in opposite directions, and the inner sides of the two semicircular limiting ring blocks 204 are formed with internal threads that match the thread grooves on the outer wall of the bidirectional threaded screw 302, the bidirectional threaded screw 302 can push the two semicircular limiting ring blocks 204 to move synchronously in different directions when rotating, so that the first thread column 202 and the second thread column 203 can be moved closer to or farther away from each other;

[0048] By controlling the rotation direction of the knob 301, the first threaded column 202 and the second threaded column 203 are brought closer to each other, and the two clamping round blocks 201 are brought closer together synchronously. When the knob 301 reaches a suitable spacing, the rotation of the knob 301 can be stopped. At this time, when the handle 206 is rotated, the handle 206 is rotated at a small angle to fully bring the two clamping round blocks 201 closer, that is, to achieve stable clamping with the guide rail.

[0049] Through the coordination of the above multiple parts, the device can be firmly clamped on the guide rail in a smaller space. At the same time, by adjusting the spacing between the first threaded column 202 and the second threaded column 203, the device can better adapt to guide rails of different widths, and the device has a wider range of applications.

[0050] Please refer to Figures 1 to 4 , one side of the knob 301 is attached to the outer wall side of the concave seat 101, and the first threaded column 202 and the second threaded column 203 are located at the eccentric position of the clamping round block 201;

[0051] A spring 4 is provided inside the telescopic circular groove 102 and is sleeved on the outside of the first threaded column 202 and the second threaded column 203 . The spring 4 is attached to the side surface of the clamping circular block 201 .

[0052] In this embodiment, the knob 301 is fitted with the outer wall side of the concave seat 101, so that when the knob 301 drives the bidirectional threaded screw 302 to rotate, the bidirectional threaded screw 302 will not move horizontally, thereby ensuring that the first threaded column 202 and the second threaded column 203 are synchronously approached or moved away;

[0053] The first threaded column 202 and the second threaded column 203 are located at the eccentric position of the clamping block 201, so that the first threaded column 202 and the second threaded column 203 can drive the clamping block 201 to move horizontally when they rotate;

[0054] The contracted spring 4 can provide thrust for the clamping block 201 , so that the first threaded column 202 and the second threaded column 203 can maintain a stable position.

[0055] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
