Description

In the process of the fixture clamping the workpiece, it is generally clamped by two sets of structures on the left and right. If the clamping end is offset, it will affect the clamping effect of the fixture on the workpiece, causing the workpiece to shift, which will affect the welding effect of the workpiece by the subsequent device.

[0024] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments of the specification;

[0025] Embodiment 1: A multi-process argon arc welding fixture provided by the present application comprises a workbench 1; clamping mechanisms 3 are installed at both ends of the top of the workbench 1, a positioning mechanism 6 is installed between the clamping mechanisms 3, and a cooling mechanism 5 is installed on the top of the clamping mechanism 3;

[0026] The positioning mechanism 6 includes a connecting rod 601, a through hole 602 and a sensor 603. The connecting rod 601 is installed at one end of the clamping mechanism 3, and the sensor 603 is installed on the outer wall of the connecting rod 601. The through hole 602 is provided inside the clamping mechanism 3 at the top of the workbench 1 away from the end of the connecting rod 601.

When the two groups of clamping mechanisms 3 are close to each other, the connecting rod 601 on one group of clamping mechanisms 3 will pass through the opening 602 inside the other group of clamping mechanisms 3. When the two groups of clamping mechanisms 3 are offset in position, the sensor 603 on the outside of the connecting rod 601 will detect a value, and the value detected by the sensor 603 will be transmitted to the external controller. If the detected pressure value is large, it means that the positions of the two groups of clamping mechanisms 3 are offset, which is convenient for workers to understand and adjust in time. The cooling mechanism 5 is used to cool the workpiece and fixture being processed.

[0028] Furthermore, telescopic rods 2 are installed at both ends of the top of the workbench 1, and the telescopic ends of the telescopic rods 2 are connected to clamping mechanisms 3;

[0029] Specifically, Figure 1 and Figure 2 As shown, in order to adjust the use spacing between the two groups of clamping mechanisms 3, the telescopic rod 2 works, and the telescopic end of the telescopic rod 2 drives the clamping mechanism 3 to move, so that the spacing between the two groups of clamping mechanisms 3 can be adjusted, which is convenient for clamping workpieces of different lengths.

[0030] Furthermore, adjusting rods 7 are installed at both ends of the top of the workbench 1, and the outer side of the adjusting rod 7 is transmission-connected with a telescopic rod 2;

[0031] Specifically, Figure 1 and Figure 2 As shown, in order to adjust the horizontal use position of the two groups of clamping mechanisms 3, the adjusting rod 7 is composed of a motor and a transmission threaded rod. By rotating the adjusting rod 7, the clamping mechanism 3 can be driven to move through the outer telescopic rod 2, thereby adjusting the horizontal use position of the clamping mechanism 3.

[0032] Further, the clamping mechanism 3 includes a fixed frame 301, a telescopic rod 2 302 and a clamping plate 303, the fixed frame 301 is installed at one end of the telescopic rod 1 2, two sets of telescopic rods 2 302 are installed inside the fixed frame 301, and the output end of the telescopic rod 2 302 is installed with a clamping plate 303;

[0033] Specifically, Figure 2 As shown, in order to clamp and fix the workpiece, the fixing frame 301 is C-shaped, and the telescopic rod 302 is arranged on the inner wall of the fixing frame 301. Through the operation of the telescopic rod 302, the telescopic end of the telescopic rod 302 will drive the clamping plates 303 to approach each other, so that the workpiece can be clamped and fixed.

[0034] Further, a plurality of sets of spring rods 4 are installed on one side close to the clamping plate 303, and a protrusion 401 is installed at one end of the spring rod 4;

[0035] Specifically, Figure 3 As shown, in order to make the clamping mechanism 3 suitable for clamping workpieces of different shapes, when the two groups of clamping plates 303 are close to each other, the spring rod 4 will be compressed, and then the multiple groups of protrusions 401 will move in position and then clamp the workpiece, so that the clamping mechanism 3 is suitable for clamping workpieces of different shapes.

[0036] Further, a pressure sensor 402 is installed at one end of the protrusion 401;

[0037] Specifically, Figure 3 As shown, in order to monitor the clamping force of the clamping mechanism 3 on the workpiece and avoid damage to the workpiece due to excessive pressure, the pressure applied by the protrusion 401 on the workpiece can be detected by the pressure sensor 402 to monitor whether the clamping force is too large.

[0038] Furthermore, the cooling mechanism 5 includes a storage box 501 and a nozzle 502. The storage box 501 is installed on the back of the fixing frame 301, and the nozzle 502 is installed on the top of the storage box 501.

[0039] Specifically, Figure 1 As shown, in order to cool the processed workpiece and the clamping mechanism 3 to avoid deformation during welding and affect its later use, liquid is stored in the storage box 501, and its interior is composed of a power structure, and its output end is connected to the nozzle 502. The liquid in the storage box 501 is sprayed to the clamping mechanism 3 or the outer surface of the workpiece through the nozzle 502, which can cool the clamping mechanism 3 and the workpiece and avoid deformation.

[0040] Working principle: The fixed frame 301 is moved by the telescopic rod 1 2, and then the workpiece is placed inside the fixed frame 301. At this time, the clamping plates 303 are driven to approach each other by the telescopic rod 2 302. When the two groups of clamping plates 303 approach each other, the spring rod 4 is compressed, and then the multiple groups of protrusions 401 are moved, and then the workpiece can be clamped and fixed.

[0041] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
