Description

Technical Field

[0001] This application relates to the technical field of tooling fixtures, and in particular to an adjustable clamping tooling. Background Technology

[0002] Currently, in fields such as machining and assembly, the clamping and fixing of pipes is an important step. Existing clamping fixtures use a fixed structure. Typically, the operator places the pipe to be worked on in the working area of ​​the clamping fixture, and the clamping fixture clamps and fixes the pipe, making it convenient for the operator to work on the pipe.

[0003] Regarding the aforementioned technologies, since fixed-structure clamping fixtures cannot achieve multi-dimensional movement and rotation adjustment, they are difficult to meet the precise clamping requirements under complex working conditions. Therefore, this application proposes an adjustable clamping fixture to meet the precise clamping requirements under complex working conditions. Utility Model Content

[0004] In view of the shortcomings of the existing technology, one of the objectives of this utility model is to provide an adjustable clamping fixture.

[0005] This application provides an adjustable clamping fixture, which adopts the following technical solution:

[0006] An adjustable clamping fixture includes a base, a frame, and clamping bolts. The base is fixedly connected to a first clamping tube. A first movable rod is slidably mounted inside the first clamping tube. A second clamping tube is fixedly connected to the end of the first movable rod away from the base, and the axes of the first clamping tube and the second clamping tube are different. A second movable rod is slidably mounted inside the second clamping tube. One end of the second movable rod is fixedly connected to the frame. The clamping bolts pass through the frame, and the tube is clamped between the clamping bolts and the frame.

[0007] By adopting the above technical solution, the adjustable clamping fixture achieves multi-dimensional adjustable clamping function. Through the sliding engagement of the first movable rod with the first clamping tube, the sliding engagement of the second movable rod with the second clamping tube, and the rotation of the first and second movable rods themselves, the fixture can meet the multi-dimensional movement and rotation of the clamp, significantly improving the flexibility of pipe clamping.

[0008] Preferably, a first fastening bolt is installed on the outer periphery of the first clamping tube, the first fastening bolt extends into the first clamping tube and abuts against the first movable rod; a second fastening bolt is installed on the outer periphery of the second clamping tube, the second fastening bolt extends into the second clamping tube and abuts against the second movable rod.

[0009] By adopting the above technical solution, the setting of the first fastening bolt and the second fastening bolt provides a locking mechanism for the first movable rod and the second movable rod, which improves the accuracy and stability of fixing after the position adjustment of the first movable rod and the second movable rod, and further enhances the versatility of pipe clamping.

[0010] Preferably, the end of the second movable rod away from the frame is connected to an extension rod.

[0011] By adopting the above technical solution, when the pipe to be clamped exceeds the sliding range of the second movable rod, the second movable rod can be fixedly connected to the extension rod to extend the moving distance of the frame in the direction of the second clamping pipe, thereby realizing long-distance clamping of the frame and the clamping bolt along the direction of the second clamping pipe.

[0012] Preferably, the axes of the first clamping tube and the second clamping tube are perpendicular to each other.

[0013] By adopting the above technical solution, the arrangement of the first movable rod along the axis of the first clamping tube and the second movable rod along the axis of the second clamping tube allows the frame to slide and adjust in two perpendicular directions within the plane formed by the two, that is, within the two-dimensional plane determined by the axis of the first clamping tube and the axis of the second clamping tube. At the same time, combined with the rotation of the first and second movable rods, the precise positioning requirements under complex working conditions are further met.

[0014] Preferably, the clamping bolt has an abutment at its end, and the frame has a clamping part.

[0015] By adopting the above technical solution, the setting of the abutment at the end of the clamping bolt and the clamping part of the frame can expand the pipe clamping interface, making the clamping interface more stable and effectively improving the stability of clamping.

[0016] Preferably, the abutment and the clamping part are arc-shaped, and the directions of their arc-shaped recesses are opposite.

[0017] By adopting the above technical solution, the clamping fixture can fit a larger area with the curved surface when clamping the curved pipe, which enhances the stability of clamping and reduces the shaking and displacement of the curved pipe during processing.

[0018] Preferably, the abutment is detachably connected to the end of the clamping bolt and is rotatable.

[0019] By adopting the above technical solution, different abutment joints can be quickly disassembled and replaced according to the shape of the pipe, expanding the application range of the clamping fixture; the rotatable feature allows the direction of the abutment joint to be adjusted in real time during the clamping process, so that it can accurately fit the surface of the pipe.

[0020] Preferably, the end of the clamping bolt away from the abutment is provided with a handle.

[0021] By adopting the above technical solution, the handle increases the force application radius and amplifies the tightening torque based on the lever principle, allowing operators to easily tighten or loosen the clamping bolts without the need for other tools. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0025] This application discloses an adjustable clamping fixture.

[0026] Reference Figure 1 An adjustable clamping fixture includes a base 1, a frame 2, and a clamping bolt 3 for clamping pipes. The frame 2 is connected to the base 1, and the clamping bolt 3 passes through the frame 2 with its end facing the pipe placed on the frame 2. By tightening the clamping bolt 3, the pipe is clamped between the clamping bolt 3 and the frame 2.

[0027] Specifically, a first clamping tube 4 is fixedly connected to the base 1. A first movable rod 5 is slidably mounted inside the first clamping tube 4. The first movable rod 5 can rotate around its axis within the first clamping tube 4. A first fastening bolt 6 is installed on the outer periphery of the first clamping tube 4, extending into the first clamping tube 4 and abutting against the first movable rod 5 to fix the first movable rod 5. The sliding and rotating cooperation between the first clamping tube 4 and the first movable rod 5 allows the first movable rod 5 to slide along the axial direction of the first clamping tube 4 and rotate around its axis.

[0028] Furthermore, a second clamping tube 7 is fixedly connected to the end of the first movable rod 5 away from the base 1, and the axes of the first clamping tube 4 and the second clamping tube 7 are in different directions. A second movable rod 8 is slidably assembled inside the second clamping tube 7. At the same time, the second movable rod 8 can rotate around its axis in the second clamping tube 7. A second fastening bolt 9 is installed on the outer periphery of the second clamping tube 7, extending into the second clamping tube 7 and abutting against the second movable rod 8. The second movable rod 8 slides with the second clamping tube 7 and rotates around its own axis, realizing the flexible adjustment of the second movable rod 8 along the axis of the second clamping tube 7.

[0029] Furthermore, one end of the second movable rod 8 is fixedly connected to the frame 2, and the other end is connected to an extension rod 10. When the pipe to be clamped exceeds the sliding range of the second movable rod 8, the extension rod 10 can be screwed to the end of the second movable rod 8 to achieve long-distance clamping along the direction of the second clamping pipe 7.

[0030] Preferably, the axes of the first clamping tube 4 and the second clamping tube 7 are perpendicular to each other. The first movable rod 5 slides along the axis of the first clamping tube 4, and the second movable rod 8 slides along the axis of the second clamping tube 7, so that the frame 2 can move precisely within a two-dimensional plane defined by the axes of the first clamping tube 4 and the second clamping tube 7, further meeting the precise positioning requirements under complex working conditions.

[0031] The clamping bolt 3 has an abutment 11 at the end for fixing the pipe, and the frame 2 has a clamping part 12 for placing the pipe at the position corresponding to the abutment 11. Preferably, the abutment 11 and the clamping part 12 are arc-shaped, and the directions of their arc-shaped concavities are opposite. When the clamping fixture clamps the pipe, the arc-shaped abutment 11 and the clamping part 12 can stably clamp and fix the pipe.

[0032] Preferably, the abutment 11 is detachably connected to the end of the clamping bolt 3 and can rotate. When the clamping bolt 3 is inserted into the frame 2, the rotatable abutment 11 can flexibly adjust the direction of the arc recess so that the recess just abuts against the surface of the pipe. The end of the clamping bolt 3 away from the abutment 11 is provided with a handle 13 for rotating the clamping bolt 3, making it easier to tighten the clamping bolt 3.

[0033] The implementation principle of this application embodiment is as follows: During operation, the adjustable clamping fixture first slides the first movable rod 5 along the axis of the first clamping tube 4, or rotates it around the axis to adjust its angle, so that the second clamping tube 7 and the frame 2 reach the vicinity of the pipe to be clamped. Subsequently, the second movable rod 8 is slid or rotated to further fine-tune the position of the frame 2. If the pipe exceeds the adjustment range of the second movable rod 8, an extension rod 10 can be screwed to its end to extend the adjustment distance. Next, the first fastening bolt 6 on the first clamping tube 4 and the second fastening bolt 9 on the second clamping tube 7 are fixed. Finally, by rotating the handle 13, the abutment 11 and the clamping part 12 are made to fit against the surface of the pipe, and the clamping bolt 3 is tightened to achieve clamping and fixing of the pipe.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
