Description

Technical Field

[0001] The utility model relates to the technical field of impeller surface treatment, in particular to a mounting surface clamping device for impeller electrophoresis. Background Art

[0002] With the development of surface treatment technology, the components of electric pumps are no longer subjected to traditional anti-rust treatment by spraying paint, but are instead subjected to electrophoresis treatment. In particular, the flow-through components of electric pumps require anti-rust surface treatment. However, as shown in the attached Figure 1 As shown, during electrophoresis, the shaft hole surface, upper mounting surface and lower mounting surface of the impeller, which are used to install components, are easily electrophoretically coated. The shaft hole surface, upper mounting surface and lower mounting surface of the impeller after coating are not accurate enough when installed with bearings and mounting screws in subsequent processes. The shaft hole surface, upper mounting surface and lower mounting surface of each impeller have to be re-finished after electrophoresis, which increases the workload and affects work efficiency.

[0014] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0015] Please attach the participation Figure 1-2 As shown, a mounting surface clamping device for impeller electrophoresis comprises a bottom plate 1 and a pressure plate 2. A plurality of support shafts 4 for placing impellers 3 and cooperating with impeller shaft hole surfaces 32 are arranged at equal intervals on the bottom plate 1. A plurality of impellers 3 can be placed on the support shafts 4 respectively, and a plurality of impellers 3 can be subjected to electrophoresis treatment in batches at one time, thereby improving work efficiency.

[0016] The support shaft 4 is fixed with a lower baffle 5, which is used to place the impeller 3 and maintain the impeller 3 between the bottom plate 1 and the pressure plate 2. The lower baffle 5 is provided with a lower plastic pad 6 for shielding the lower mounting surface 33 of the impeller. The lower plastic pad 6 can seal the lower mounting surface 33 of the impeller and the impeller shaft hole surface 32 to prevent the lower mounting surface 33 of the impeller and the impeller shaft hole surface 32 from being affected by the electrophoresis liquid, which is not conducive to subsequent installation. Preferably, the lower plastic pad 6 is in a truncated cone shape; similarly, the support shaft 4 An upper plastic pad 7 for shielding the upper mounting surface 31 of the impeller is also sleeved thereon. The upper plastic pad 7 is also used to seal the impeller shaft hole surface 32 and the upper mounting surface 31 of the impeller. The diameters of the upper plastic pad 7 and the lower plastic pad 6 are both larger than the diameter of the shaft hole of the impeller 3, ensuring that the electrophoresis liquid does not enter the shaft hole of the impeller 3. At the same time, the upper plastic pad 7 and the lower plastic pad 6 prevent the impeller 3 from directly contacting the lower baffle plate 5 or the pressure plate 2, thereby avoiding scratching the upper mounting surface 31 of the impeller and the lower mounting surface 33 of the impeller, thereby affecting the assembly accuracy.

[0017] The pressing plate 2 is provided with through holes (not shown in the drawings) corresponding to the support shaft 4 one by one. The pressing plate 2 moves downward along the support shaft 4 through the through holes to press the upper plastic pad 7 onto the impeller 3. A compression spring 8 sleeved on the support shaft 4 is provided between the pressing plate 2 and the upper plastic pad 7. The spring 8 is compressed downward by the gravity of the pressing plate 2 itself, and then the spring 8 presses the upper plastic pad 7 and the impeller 3 downward. The spring 8 keeps a certain distance between the pressing plate 2 and the upper surface of the impeller 3, so that the electrophoresis coating of the remaining upper surface of the impeller 3 is convenient; specifically, the impeller 3 is at The lower plastic pad 6 and the lower baffle 5 are pressed downward by their own gravity and the pressure plate 2, that is, the upper plastic pad 7 and the lower plastic pad 6 respectively seal the impeller upper mounting surface 31 and the impeller lower mounting surface 33, so that the electrophoresis liquid will not be coated on the impeller shaft hole surface 32, the impeller upper mounting surface 31 and the impeller lower mounting surface 33, and the electrophoresis liquid will only be coated on the remaining surfaces of the impeller 3. Multiple impellers 3 can be electrophoresed at one time, and after electrophoresis, there is no need to fine-tune the mounting surfaces on the impeller 3 one by one for a second time, and assembly can be carried out, which ensures assembly accuracy and improves work efficiency.

[0018] In the above embodiment, preferably, in order to improve the stability of the entire device, the height of the support shaft 4 at both ends of the bottom plate 1 is made higher than the height of the support shaft 4 in the middle part, and an external thread is provided on the top end. After the impellers 3 are installed and placed on the support shaft 4 one by one, the corresponding upper plastic pads 7 and springs are placed, and finally the pressure plate 2 is placed. The pressure plate 2 cooperates with the external threads of the support shafts 4 at both ends through nuts to tighten the spring 8, and firmly fixes the impeller 3 between the pressure plate 2 and the bottom plate 1; at the same time, the fixed pressure plate 2 makes it easy to take the entire device out of the electrothermal pool, and the operation is simple and convenient.
