[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A fixing fixture for processing an electric heater water cover tank includes a base 1, a back plate 2, a clamping plate 3, a driving device, and a transmission device. The back plate 2 is installed on the top wall of the base 1. A slide rail 4 is horizontally installed on the front side wall of the back plate 2. Two sets of sliders 5 are slidably installed on both ends of the slide rail 4. The clamping plate 3 is fixedly installed on the front side wall of each set of sliders 5. A clamping groove 6 is opened at the end of each set of clamping plates 3 that is close to each other. Both ends of the clamping groove 6 are designed with bevels. A connecting plate 7 is installed on the top wall of each set of sliders 5. The rear bottom wall of each set of connecting plates 7 is connected to the driving device. The driving device is driven by the transmission device. Support legs 8 are installed at the four corners of the bottom of the base 1. In this embodiment, when in use, the electric heater water cover tank to be processed is placed on the base 1, between the two sets of clamping plates 3. The driving device drives the connecting plate 7 to move through the transmission device. This causes the two sets of sliders 5 to move laterally along the slide rail 4. The two sets of sliders 5 drive the two sets of clamping plates 3 to move from both ends toward the middle, gradually clamping the water cover box. The clamping groove 6 has an angled design at both ends, which can achieve good fit and clamping regardless of whether the water cover box is round or rectangular. For cylindrical water cover boxes, the angled design can automatically guide the workpiece to the center position to achieve centered clamping. For rectangular water cover boxes, both ends of the clamping plate 3 can contact the edges and corners of the workpiece to achieve multi-point stable clamping. After clamping, the fixture can maintain the clamped state to ensure that the water cover box will not shift or loosen during drilling, milling, welding and other processing. After processing, the conveying device drives the driving device to open the clamping plate 3, release the water cover box, and replace it with a new workpiece to be processed. The above process is repeated. The slide rail 4 and slider 5 system, together with the clamping plate 3, provides uniform clamping force distribution and stable clamping. The design of the clamping groove 6 improves the versatility and flexibility of the fixture.

[0025] Preferably, in this embodiment, the driving device includes a fixed plate 9, a bidirectional screw 10, and a moving block 11. Two sets of fixed plates 9 are symmetrically installed on the back wall of the back plate 2. The bidirectional screw 10 is rotatably installed between the two sets of fixed plates 9. The moving blocks 11 are threadedly installed at both ends of the bidirectional screw 10. The top walls of the two sets of moving blocks 11 are fixedly connected to the bottom wall of the connecting plate 7 away from the clamping plate 3. When the transmission device is started, the transmission device drives the bidirectional screw 10 to rotate. After the screw rotates, since the thread directions at the left and right ends are opposite, the two moving blocks 11 will move closer to each other along the screw axis. The moving blocks 11 drive the slider 5 to slide synchronously on the slide rail 4 through the connecting plate 7 to achieve clamping and fixing of the water cover box. When the bidirectional screw 10 rotates in the opposite direction through the transmission device, the water cover box is released and can be taken out to replace the new workpiece to be processed.

[0026] Preferably, in this embodiment, a guide rod 12 is installed above the bidirectional screw 10, and both sets of moving blocks 11 are slidably connected to the guide rod 12. When the bidirectional screw 10 rotates, simple thread transmission may cause the moving blocks 11 to rotate slightly. However, by restricting the moving blocks 11 to move only in a straight line through the guide rod 12, this situation can be effectively avoided, ensuring that the moving blocks 11 move smoothly along the predetermined trajectory. The guide rod 12 provides additional support points for the moving blocks 11, enhancing the rigidity and stability of the entire mechanism. Especially when subjected to large loads or high-speed operation, it can reduce vibration and shaking, ensuring machining accuracy. The guide rod 12 shares some of the lateral force generated by the workpiece weight and clamping force, reducing the pressure on the bidirectional screw 10, thereby slowing down the wear rate of the screw and extending its service life.

[0027] Preferably, in this embodiment, the transmission device includes a driving wheel 13, a driven wheel 14, a conveyor belt 15, and a drive motor 16. The driven wheel 14 is sleeved in the middle of the bidirectional screw 10, and the drive motor 16 is installed on the side wall of the back plate 2. The driving wheel 13 is installed at the output end of the drive motor 16. The driving wheel 13 and the driven wheel 14 are connected by the conveyor belt 15. When it is necessary to clamp or release the water cover tank of the electric heater, the drive motor 16 installed on the side wall of the back plate 2 is first started by the control system. The output end of the drive motor 16 is connected to the driving wheel 13. After the drive motor 16 is started, it will drive the driving wheel. 13 rotates, and the driving wheel 13 is connected to the driven wheel 14 through the conveyor belt 15 surrounding it. As the driving wheel 13 rotates, the conveyor belt 15 starts to move and transmits power to the driven wheel 14. The driven wheel 14 is sleeved in the middle of the bidirectional screw 10. Therefore, when the driven wheel 14 rotates with the movement of the conveyor belt 15, it will directly drive the bidirectional screw 10 to rotate. Since the two ends of the bidirectional screw 10 have threads with opposite directions of rotation, when the bidirectional screw 10 rotates, the two sets of moving blocks 11 (i.e. nuts) will move closer or further away from each other along the axial direction under the guidance of the guide rod 12, and then drive the slider 5 and the clamping plate 3 through the connecting plate 7 to complete the clamping or loosening action.

[0028] Preferably, in this embodiment, the drive motor 16 is a servo motor. A servo motor can achieve very precise position control, which means that the clamping plate 3 can be accurately positioned to the required position, ensuring that the workpiece is clamped evenly and precisely, and avoiding workpiece deformation or damage caused by uneven clamping force.

[0029] Preferably, in this embodiment, both the slide rail 4 and the slider 5 are T-shaped designs. The T-shaped structure has good anti-deflection ability and can effectively prevent the slider 5 from tilting or flipping during sliding. The T-shaped guide rail and the slider 5 have a certain self-centering characteristic, which makes it easier to position during assembly and reduces installation errors.

[0030] Preferably, in this embodiment, limit plates 17 are installed at both ends of the slide rail 4. The limit plates 17 are installed at both ends of the slide rail 4, which can effectively prevent the slider 5 from sliding off the guide rail due to excessive travel during the movement.

[0031] Preferably, in this embodiment, the inner wall of the clamping groove 6 is provided with an elastic buffer layer. During the clamping process, the elastic buffer layer can effectively prevent the clamping plate 3 from directly contacting the workpiece surface, thereby preventing appearance defects such as scratches, indentations or abrasions, which is especially suitable for water cover box products with high surface requirements.

The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
