[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] Please refer to Figure 1-2 , an embodiment of the utility model provides a single-cylinder bidirectional sliding fixture structure, comprising:

[0032] Bottom plate 1;

[0033] The slide rail 2 is fixedly disposed on the top surface of the bottom plate 1 and is provided with a first end 21 and a second end 22 opposite to each other;

[0034] A sliding assembly 3 is slidably connected to the slide rail 2;

[0035] The driving cylinder 4 is fixedly arranged on the top surface of the bottom plate 1 and is transmission-connected with the sliding assembly 3;

[0036] The clamping member 5 is disposed on one side of the sliding assembly 3 close to the first end 21;

[0037] The fine-tuning frame assembly 6 is fixedly connected to the sliding assembly 3 and the clamping member 5, respectively, and is used for adaptively fine-tuning the clamping member 5 relative to the sliding assembly 3 by ±3-4°;

[0038] The limit assembly 7 is fixedly disposed on the top surface of the bottom plate 1 and is used to limit the sliding travel of the sliding assembly 3 along the slide rail 2 .

[0039] In this embodiment, when clamping and fixing the parts, the driving cylinder 4 drives the sliding assembly 3 to move along the slide rail 2. When the clamping member 5 is against the part, the fine-tuning frame assembly 6 adaptively fine-tunes a certain angle to make the clamping member 5 fit the part more closely, thereby improving the clamping and fixing effect of the part.

[0040] When the sliding assembly 3 moves along the slide rail 2, the limit assembly 7 limits its movement in two directions, thereby avoiding the problem of the sliding assembly 3 and the slide rail 2 slipping off and improving the safety of the clamp structure.

[0041] In some embodiments, the clamping member 5 is a clamping block or a clamping plate, and the clamping member 5 may also be provided with a profile that matches the external structure of the part.

[0042] In a preferred embodiment, if Figure 1 and Figure 2As shown, the fine-tuning frame assembly 6 includes a support beam 61 fixedly arranged at the top of the sliding assembly 3 near the first end 21, the support beam 61 is perpendicular to the slide rail 2, a fine-tuning beam 62 is arranged in parallel on one side of the support beam 61 near the first end 21, a first connecting member 63 is fixedly arranged on one side of the support beam 61, a second connecting member 64 is fixedly arranged on one side of the fine-tuning beam 62, the second connecting member 64 is rotatably connected to the first connecting member 63 through a vertical shaft 65, first connecting columns 66 are symmetrically fixedly arranged at both ends of the fine-tuning beam 62, and the support beam 61 A second connecting column 67 corresponding to the first connecting column 66 is arranged on it, and the corresponding first connecting column 66 is connected to the second connecting column 67 through a tension spring 68. Adjusting bolts 69 are symmetrically arranged at both ends of the fine-tuning beam 62 close to the support beam 61. The adjusting bolts 69 are vertically threadedly connected to the fine-tuning beam 62. A first supporting nut 610 is arranged on the adjusting bolt 69, and a first limiting block 611 is fixedly arranged on the support beam 61 corresponding to the adjusting bolt 69; the clamping member is fixedly arranged on one side of the fine-tuning beam 62 close to the first end.

[0043] In this embodiment, the fine-tuning beam 62 is connected to the support beam 61 by the first connecting member 63, the second connecting member 64 and the shaft 65. The tension springs 68 on both sides ensure that the fine-tuning beam 62 is always parallel to the support beam 61 without external force, so that the clamping member 5 is positioned before clamping without being skewed. The first support nut 610 cooperates with the first limit block 611 to limit the rotation angle of the fine-tuning beam 62, avoiding the problem of clamping failure due to excessive rotation angle. The fine-tuning frame assembly 6 realizes adaptive fine-tuning of the clamping member 5, improving the clamping effect of the parts.

[0044] In a preferred embodiment, the clamping member 5 is fixedly connected to the fine-tuning beam 62 by bolts, and the clamping member 5 can be replaced according to the clamping requirements of different parts, with good adaptability.

The sliding assembly 3 is slidably connected to the slide rail 2 through the slider 31, and is connected to the driving cylinder 4 and the fine adjustment frame assembly 6 through the frame plate 32.

[0046] In a preferred embodiment, if Figure 1 and Figure 2 As shown, the limiting assembly 7 includes a first supporting seat 71 and a second supporting seat 72;

[0047] The first support seat 71 is fixedly arranged on the top surface of the bottom plate 1 at the first end 21, and a first limiting bolt 73 is threadedly connected to the first support seat 71 corresponding to the slider 31, and a second supporting nut 74 is arranged on the first limiting bolt 73;

[0048] The second support seat 72 is fixedly arranged on the top surface of the base plate 1 and located on the outside of the second end 22.

A second limiting block 77 is fixedly arranged on the second support seat 72 corresponding to the second limiting bolt 75.

[0049] In this embodiment, the sliding assembly 3 slides along the slide rail 2 toward the first end 21, and reaches the maximum forward stroke when the slider 31 abuts against the first limit bolt 73; the sliding assembly 3 slides along the slide rail 2 toward the second end 22, and reaches the maximum backward stroke when the second limit bolt 75 abuts against the second limit block 77.
