[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides a clamping and fixing device, such as Figure 1-4 As shown, the clamping and fixing device includes: a support frame 1; a support plate 2 installed in the support frame 1 for receiving the pin terminal body 3; a threaded rod 4 threadedly installed on the support frame 1; a clamping plate 5 rotatably installed at the bottom of the threaded rod 4 for squeezing and stabilizing the pin terminal body 3; an adjustment block 6 fixed on the top of the threaded rod 4, and a plurality of cut surfaces are provided on the adjustment block 6; and an adjustment component arranged on the support frame 1 for stabilizing the top of the pin terminal body 3.

[0023] In this embodiment, the support frame 1 serves as the basic structure of the entire device and provides a stable supporting environment. The support plate 2 is used to receive the pin terminal body 3 to prevent it from moving during the processing. By rotating the threaded rod 4, the distance between the clamping plate 5 and the support plate 2 can be adjusted, thereby achieving stable extrusion of the pin terminal body 3. This design is not only convenient for operation, but also can effectively fix the pin terminal body 3 to prevent it from moving during the welding process. By rotating the adjustment block 6, the rotation angle of the threaded rod 4 can be easily adjusted to achieve precise control of the clamping plate 5. This design greatly improves the convenience and accuracy of operation. Through the action of the adjustment component, the pin terminal body 3 can be further fixed to ensure its stability during the welding process.

[0024] In a further preferred embodiment of the utility model, the adjustment assembly includes a mounting plate 14 slidably mounted on the support frame 1; a spring 15 fixed to the bottom of the mounting plate 14; and a fixing block 16 installed at the bottom of the spring 15 for stabilizing the tip of the pin terminal body 3, and the fixing block 16 can contact the surface of the workbench used for welding thermocouple welding points.

[0025] In this embodiment, the mounting plate 14 can be slidably adjusted on the support frame 1 to adapt to pin terminal bodies 3 of different lengths or different fixing requirements. The spring 15 has a certain elasticity and restoring force. When the fixing block 16 is subjected to external force, the spring 15 can provide a buffer for it, while ensuring that the fixing block 16 always maintains close contact with the workbench surface, thereby achieving stability of the tip of the pin terminal body 3. The design of the fixing block 16 can be in contact with the workbench surface used for welding thermocouple welding points, ensuring that during the welding process, the tip of the pin terminal body 3 can remain stable to prevent the welding quality from being affected by movement or shaking.

[0026] In a further preferred embodiment of the utility model, a plurality of electric telescopic rods 7 are installed at the bottom of the support frame 1, and the same base 8 is fixed on the output rods of the plurality of electric telescopic rods 7. A plurality of universal wheels 9 are installed at the bottom of the base 8, and a self-locking structure is provided on the plurality of universal wheels 9.

[0027] In this embodiment, the height of the entire clamping and fixing device can be adjusted by extending and retracting the electric telescopic rod 7 to adapt to different working environments and operating requirements. The universal wheels 9 allow the entire device to be easily moved and transferred. The self-locking structure can lock the universal wheels 9 when the device position needs to be fixed to prevent the device from sliding or moving, thereby improving the flexibility and convenience of the device, allowing the operator to easily move and adjust the position and height of the device, and also ensuring the stability of the device during operation through the self-locking structure.

[0028] In a further preferred embodiment of the utility model, a slide groove is provided on the top of the support frame 1, and a slider 12 connected to the mounting plate 14 is slidably installed in the slide groove. A plurality of balls 19 are inlaid on the slider 12 and are in contact with the inner wall of the slide groove. A handle 13 is fixed on the top of the slider 12.

[0029] In this embodiment, the sliding of the slider 12 in the slide groove can drive the mounting plate 14 and the spring 15 and the fixing block 16 thereunder to move together. This design not only simplifies the adjustment process, but also improves the accuracy and stability of the adjustment. The presence of the ball 19 reduces the friction between the slider 12 and the inner wall of the slide groove, making the slider 12 slide more smoothly in the slide groove, further improving the convenience and efficiency of the adjustment. The operator can easily move the slider 12 by holding the handle 13, thereby achieving position adjustment of the mounting plate 14 and the components thereunder.

[0030] In a further preferred embodiment of the utility model, a limit plate 10 which can contact the sliding block 12 is slidably installed in the slide groove, and a plurality of adjusting bolts 11 are threadedly installed on the support frame 1. The plurality of adjusting bolts 11 all extend into the slide groove and can all contact the limit plate 10.

[0031] In this embodiment, the limit plate 10 can contact the slider 12 to limit its range of motion. By rotating the adjusting bolt 11, the contact position between it and the limit plate 10 can be changed, thereby adjusting the position of the limit plate 10 in the slide groove. In this way, when the slider 12 slides in the slide groove, it will be restricted by the limit plate 10. The position of the slider 12 and the mounting plate 14, spring 15 and fixed block 16 connected to it can be precisely controlled according to actual needs. By adjusting the position of the limit plate 10, it can be ensured that these components can stop stably when moving to a specific position, thereby achieving precise fixation of the pin terminal body 3.

[0032] In a further preferred embodiment of the utility model, a limiting telescopic rod 17 is provided in the spring 15 , and the limiting telescopic rod 17 is installed between the mounting plate 14 and the fixing block 16 , and observation windows 18 are provided on both sides of the support frame 1 .

[0033] In this embodiment, the limiting telescopic rod 17 can ensure that when the spring 15 is compressed or stretched, its deformation process is more stable, avoiding excessive deformation or offset, thereby ensuring that the fixing block 16 stably fixes the pin terminal body 3. The observation window 18 allows the operator to observe the internal working status through the observation window 18 without opening the support frame 1, including the fixing status of the pin terminal body 3, the working status of the spring 15 and the limiting telescopic rod 17, etc. This design not only improves the safety of operation, but also facilitates the operator to monitor and adjust the device in real time.

[0034] In a further preferred embodiment of the present invention, anti-slip pads 20 are installed on the sides of the support plate 2 and the clamping plate 5 that are close to each other, and the clamping plate 5 is in sliding contact with the inner wall of the support frame 1.

[0035] In this embodiment, the anti-slip pad 20 has excellent anti-slip properties and can increase the friction with the contact surface of the pin terminal body 3, thereby effectively preventing it from sliding or falling off during processing. The sliding contact between the clamp 5 and the inner wall of the support frame 1 ensures that the clamp 5 can move smoothly and steadily when adjusting the position without jamming or offsetting, which further improves the stability and accuracy of clamping.

[0036] In a further preferred embodiment of the utility model, a plurality of limit rods are fixed on the limit plate 10, and the plurality of limit rods can extend outside the slide groove. The base 8 is U-shaped, and the base 8 can be mounted outside a workbench for welding thermocouple welding points.

[0037] In this embodiment, the design of the limit rod makes the position of the limit plate 10 in the slide groove more stable and not easily moved by external interference. The existence of the limit rod also facilitates the operator to adjust the position of the limit plate 10, thereby improving the convenience of operation. The base 8 can be conveniently mounted on the outside of the workbench used for welding thermocouple welding points. Such a design not only enhances the stability of the device, but also enables the entire clamping and fixing device to be more closely combined with the workbench, thereby improving the stability and safety during the processing.

[0038] To sum up, compared with the related technology, the present device can protect the processing environment by setting up the support frame 1, can clamp and fix the pin terminal body 3 by setting up the support plate 2 and the clamping plate 5, and can further stabilize the end of the pin terminal body 3 on the welding workbench by setting the spring 15 and the fixing block 16, thereby further increasing the stability during the processing of the thermocouple.
