[0032] To describe in detail the technical content, achieved purpose and effects of the present utility model, the following is described in conjunction with the implementation manners and with reference to the accompanying drawings.

[0033] The existing clamping mechanism directly clamps the C-shaped rail through the jaws. During the stretch bending production, the deformation of the rail may cause loosening, affecting the clamping effect.

[0034] Based on this, please refer to Figures 1 to 4 , the present utility model provides a rail clamping tooling, including a first jaw 1, a central positioning member 3 and a second jaw 2; the first jaw 1 has a first clamping surface 11, the central positioning member 3 is slidably connected to the first jaw 1, and the second jaw 2 is arranged on the side of the central positioning member 3 away from the first jaw 1; the second jaw 2 can move along the side perpendicular to the first clamping surface 11 and push the central positioning member 3 to slide in the direction close to the first jaw 1; a central clamping surface 31 is provided on the side of the central positioning member 3 close to the first clamping surface 11.

[0035] When clamping, the center positioning member 3 extends into the inside of the guide rail. After the second jaw 2 pushes the center clamping member to slide, the distance between the center clamping surface 31 and the first clamping surface 11 is reduced, and then the wall surface of the guide rail is clamped. The clamped wall surface of the guide rail will not be deformed under the action of the center clamping surface 31 and the first clamping surface 11 during the subsequent bending process, so that this part is tightly clamped. Specifically, those skilled in the art can adaptively adjust the shape of the center positioning member 3 according to the structure of the guide rail, as long as the center clamping surface 31 and the first clamping surface 11 can be closely attached to the wall surface of the guide rail, and no specific limitation is made. Specifically, the guide rail is a C-shaped guide rail. When clamping, the wall surface of the guide rail is clamped between the center positioning member 3 and the first jaw 1. The guide rail semi-covers the center positioning member 3, so that the side of the center positioning member 3 away from the first jaw 1 is at the side opening of the C-shaped guide rail, which is convenient for the second jaw 2 to directly push the center positioning member 3 and ensure a uniform clamping effect.

[0036] It can be understood that the guide rail clamping tooling provided by the present invention is provided with a slidable center positioning member 3 on the first jaw 1. When clamping, the center positioning member 3 is nested into the guide rail and closely attached to the wall surface of the guide rail. During the bending process of the guide rail, it is not affected by the deformation of the guide rail, ensuring the clamping effect.

[0037] In some embodiments, as Figure 4 shown, a sliding channel 13 is provided in the first jaw 1, and the distribution direction of the sliding channel 13 is perpendicular to the first clamping surface 11; the center positioning member 3 has a sliding member 34, and the sliding member 34 is arranged in the sliding channel 13. The distribution direction of the sliding channel 13 is perpendicular to the first clamping surface 11, so that the distance between the center positioning member 3 and the first jaw 1 is kept consistent as a whole. When clamping the guide rail, it can ensure that each position is closely attached. At the same time, the setting of the sliding channel 13 and the sliding member 34 makes the sliding track of the center positioning member 3 fixed, restricting the center positioning member 3 from sliding in other directions. To ensure that during the bending production process of the guide rail, when the guide rail conducts the tensile force to the center positioning member 3, the center positioning member 3 does not shift in other directions, ensuring the tightness of the clamping.

[0038] In some embodiments, as Figure 4 shown, a return spring 14 is provided between the center positioning member 3 and the inner wall of the first jaw 1, and the return spring 14 is used to push the center positioning member 3 to slide in a direction away from the first jaw 1. The setting of the return spring 14 makes the center positioning member 3 away from the first jaw 1 when not subjected to the thrust of the second jaw 2, which is convenient for the operator to load and unload materials.

[0039] In some embodiments, the guide rail clamping tooling further includes a limiting structure disposed on the first jaw 1 and / or the center positioning member 3, and the limiting structure restricts the sliding distance of the center positioning member 3. The limiting structure can prevent the center positioning member 3 from sliding too far, causing the center positioning member 3 to disengage from the first jaw 1, facilitating the operator to adjust the position of the center positioning member 3 for loading and unloading. Specifically, the limiting structure can adopt solutions such as setting a limiting block on the first jaw 1 and a corresponding groove on the center positioning member 3; or setting a limiting block on the center positioning member 3 and a corresponding groove inside the first jaw 1; or the first jaw 1 extending a limiting block and abutting against the center positioning member 3 by the side surface of the first jaw. Those skilled in the art can choose the setting form of the limiting structure according to the actual situation without specific limitations.

[0040] In some embodiments, as Figure 4 shown, a limiting groove 15 is formed on the first jaw 1, and the limiting groove 15 communicates with the sliding channel, and the distribution direction of the limiting groove 15 is parallel to the distribution direction of the sliding channel; a limiting screw is provided on the sliding member 34, and the limiting screw 35 extends into the limiting groove 15. The limiting groove 15 is provided on the first jaw 1, penetrates the sliding channel, and cooperates with the limiting screw 34 on the sliding member 34 to play a limiting role. This setting form is simple and stable, and the assembly is simple. Further, a limiting groove 15 can be selected to be formed on the sliding member 34, and the distribution direction of the limiting groove 15 is parallel to the sliding direction of the sliding member 34; a limiting screw 35 is provided on the first jaw 1, and the limiting screw 35 extends into the limiting groove 15. When the limiting groove 15 is formed on the sliding member 34, the limiting groove 15 is located inside the first jaw 1, which can avoid problems such as loose clamping and too short sliding distance caused by foreign objects entering the limiting groove 15. Furthermore, when the limiting groove 15 is formed on the sliding member 34, the depth of the limiting groove 15 is set in a gradient manner, and in cooperation with the extending distance of the limiting screw 35, the operator can conveniently adjust the sliding distance of the center positioning member 3, improving work efficiency. At the same time, the operator can adjust the friction force between the limiting screw 35 and the limiting groove 15 to adjust the sliding speed and the force required for sliding of the center positioning member 3. Those skilled in the art can choose the setting positions of the limiting groove 15 and the limiting screw 35 according to needs,

[0041] In some embodiments, as Figure 1 and Figure 2As shown, the first clamping jaw 1 also includes a supporting surface 12, which is perpendicular to the first clamping surface 11. The center positioning member 3 has an auxiliary clamping surface 33 on the side near the supporting surface 12, and the center clamping surface 31 is parallel to the first clamping surface 11. The first clamping surface 11, supporting surface 12, auxiliary clamping surface 33, and center clamping surface 31 together form an L-shaped clamping space. This L-shaped clamping space supports and positions the guide rail, ensuring that it can be placed on the guide rail clamping fixture before clamping. After placement, it does not need to be held, improving work efficiency and safety.

[0042] In some embodiments, a positioning piece 4 is further included. Positioning piece 4 is connected to first clamping jaw 1 and is perpendicular to first clamping surface 11. Positioning piece 4 is provided with a loading port 41. The projected area of loading port 41 on first clamping jaw 1, parallel to first clamping surface 11, partially overlaps first clamping surface 11 and supporting surface 12. Positioning piece 4 facilitates the operator to directly insert the guide rail into the L-shaped clamping space of the guide rail clamping fixture through loading port 41. While positioning, it also prevents the operator's fingers from entering the clamping space, further improving safety.

[0043] In some embodiments, as Figure 2 As shown, the second clamping jaw 2 includes a second clamping surface 22 and an abutting surface 21. The abutting surface 21 abuts against the center positioning member 3. The second clamping surface 22 is located on the side of the abutting surface 21 away from the supporting surface 12. The second clamping surface 22 is parallel to the first clamping surface 11. When the guide rail adopts a C-type guide rail, the center positioning member 3 is half-covered by the guide rail during clamping, and the abutting surface 21 directly contacts the center positioning member 3, so that the center positioning member 3 is subjected to a uniform thrust, which is then converted into a uniform clamping force. At the same time, the second clamping surface 22 adopts a design parallel to the first clamping surface 11. While the center positioning member 3 and the first clamping jaw 1 clamp the wall surface, it can assist in clamping other parts of the guide rail, so that the guide rail is subjected to uniform force as a whole during bending, thereby ensuring the forming effect.

[0044] In some embodiments, the center positioning member 3 also includes a pressure-bearing surface 32, which abuts the abutting surface 21; the pressure-bearing surface 32 is parallel to the center clamping surface 31; in a direction perpendicular to the pressure-bearing surface 32, the projection area of the center clamping surface 31 on the pressure-bearing surface 32 is located within the pressure-bearing surface 32. The pressure-bearing surface 32 is parallel to the center clamping surface 31, and can evenly convert the thrust transmitted by the abutting surface 21 into a clamping force on the guide rail, thereby ensuring the clamping effect. At the same time, the projection area of the center clamping surface 31 is limited to be located within the pressure-bearing surface 32, that is, the center positioning member 3 as a whole is a stepped structure with a smaller side close to the first clamping jaw 1 and a larger side away from the first clamping jaw 1. This not only ensures the structural stability of the center clamping member, but also increases the pressure on the guide rail, thereby improving the stability of the clamping.

[0045] In some embodiments, the surface of the first clamping surface 11 is provided with a toothed portion. The toothed structure of the toothed portion can increase the pressure applied to the guide rail, strengthen the clamping effect, and prevent slippage caused by an overly smooth first clamping surface 11. Specifically, the toothed portion is provided with clamping teeth on the surface of the first clamping surface 11, which changes surface contact to line contact, increases pressure, and improves the clamping effect.

[0046] The guide rail applicable to this embodiment is a guide rail having an opening on one side of the guide rail, such as a C-shaped guide rail.

[0047] Please refer to Figures 1 to 4 , the first embodiment of the present utility model is:

[0048] A guide rail clamping tool includes a first clamping jaw 1 having a first clamping surface 11; a center positioning member 3, which is slidably connected to the first clamping jaw 1; a second clamping jaw 2, which is arranged on the side of the center positioning member 3 away from the first clamping jaw 1; the second clamping jaw 2 can move along the side perpendicular to the first clamping surface 11 and push the center positioning member 3 to slide in the direction close to the first clamping jaw 1; a center clamping surface 31 is provided on the side of the center positioning member 3 close to the first clamping surface 11; a sliding channel 13 is provided in the first clamping jaw 1, and the distribution direction of the sliding channel 13 is perpendicular to the first clamping surface 11; the center positioning member 3 has a sliding member 34, and the sliding member 34 is arranged in the sliding channel 13.

[0049] In this embodiment, a limiting groove 15 is provided on the first clamping jaw 1, the limiting groove 15 is connected to the sliding channel, and the distribution direction of the limiting groove 15 is parallel to the distribution direction of the sliding channel; a limiting screw is provided on the sliding member 34, and the limiting screw 35 extends into the limiting groove 15.

[0050] In this embodiment, the first clamping jaw 1 also includes a supporting surface 12, which is perpendicular to the first clamping surface 11; the center positioning member 3 is provided with an auxiliary clamping surface 33 on the side close to the supporting surface 12, and the center clamping surface 31 is parallel to the first clamping surface 11. The first clamping surface 11, the supporting surface 12, the auxiliary clamping surface 33 and the center clamping surface 31 together form an L-shaped clamping space.

[0051] In this embodiment, a return spring 14 is provided between the central positioning member 3 and the inner wall of the first clamping jaw 1 , and the return spring 14 is used to push the central positioning member 3 to slide in a direction away from the first clamping jaw 1 .

[0052] In this embodiment, a positioning piece 4 is also included, which is connected to the first clamping jaw 1 and is perpendicular to the first clamping surface 11; the positioning piece 4 is provided with a loading port 41, and the loading port 41 is projected on the first clamping jaw 1 in a direction parallel to the first clamping surface 11, and the projection area of the loading port 41 on the first clamping jaw 1 partially overlaps with the first clamping surface 11 and the supporting surface 12.

[0053] The working principle of the present utility model is as follows: When not clamping, the reset spring 14 pushes the central positioning member 3 to slide away from the first jaw 1, and the central positioning member 3 stays at the initial position under the action of the limiting structure. At this time, the first clamping surface 11, the supporting surface 12, the auxiliary clamping surface 33 and the central clamping surface 31 enclose a clamping space in an L shape. When starting to clamp, the operator inserts the wall surface of the guide rail into the clamping space through the feeding port 41, and the second jaw 2 starts to move along the side perpendicular to the first clamping surface 11, pushing the central positioning member 3 to slide towards the first jaw 1, so that the clamping space shrinks until the wall surface of the guide rail is completely attached to the central clamping surface 31 and the first clamping surface 11, that is, the clamping action is completed.

[0054] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly.
