The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0026] In addition, the described features, structures or characteristics may be combined in one or more example embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the example embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. may be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0027] The utility model provides Figure 1-Figure 7 The clamping structure of a volute shown in the figure includes a base 1 placed in a processing equipment. The so-called processing equipment can be a drilling equipment, a grinding equipment, etc., which is not specifically limited here. The base 1 includes a seat body 11 and a step surface 12. The seat body 11 is fixed to the frame of the processing equipment through a detachable fastener. The upper end surface of the step surface 12 opened in the seat body 11 is used to support the volute, and a space is left at the lower end of the step surface 12 to facilitate the placement of the volute.

[0028] The clamping mechanism 2 is mainly used for clamping volutes of various shapes, and includes a clamping plate 21, a clamping plate 22, a clamping head 23 and an adapter 24. A clamping plate 21 is fixed on the higher end face of the step face 12, and the side end of the clamping plate 21 is rotatably connected to the clamping plate 22 through the adapter 24. The clamping plate 22 can be folded up relative to the seat body 11. Slide grooves are provided on the clamping plates 21 and 22, and a plurality of clamping heads 23 are sealed and slidably connected in the slide grooves.

[0029] The driving mechanism 3 includes an injection tube 31 and an infusion channel 32. The infusion channel 32 is opened inside the clamping plate 1 21 and the clamping plate 2 22. The injection tube 31 is connected to the corresponding slide groove through the infusion channel 32. The injection tube 31 is connected to an external pressure device, such as a hydraulic pump, so that the hydraulic pump pumps hydraulic oil into the injection tube 31 and the infusion channel 32, and uses the pressure of the hydraulic oil to drive the corresponding clamping head 23 to extend from the slide groove.

[0030] For example, when the side surfaces of a volute with different curvatures are squeezed by a plurality of clamping heads 23, the pressure of the hydraulic oil will push the clamping heads 23 to slide out of the slide grooves and clamp the side surfaces of the volute. During this clamping process, although the clamping paths are different and the stroke sizes of the clamping heads 23 are different, the clamping forces are relatively uniform due to the pressure of the hydraulic oil, thereby improving the stability of the clamping of the volute.

[0031] Preferably, the clamping head 23 may include a straight head 231 and a lateral head 232, and the straight head 231 and the lateral head 232 are both installed in the same manner and are connected to the adjacent surfaces of the clamping plate 1 21 or the clamping plate 2 22 in a closed sliding manner through the driving mechanism 3, so that in the process of clamping the volute, more supporting points can be used to achieve the clamping purpose of the volute.

[0032] It should be noted that, in the above process, there must be a clamping head 23 that is not in direct contact with the volute, but this should not affect the working state of the other clamping heads 23 in the clamping state.

[0033] Preferably, the clamping plate 1 21 and the clamping plate 2 22 can form a circular ring shape, and the position of the adapter 24 can be specifically designed according to the needs of the user.

[0034] Preferably, the clamping plate 1 21 and the clamping plate 2 22 can form an elliptical ring, wherein the clamping plate 2 22 is the long side and can clamp a longer volute.

[0035] The adapter 24 includes a joint connecting body 1 241 and a joint connecting body 2 242, both of which are hollow structures. The joint connecting body 1 241 and the joint connecting body 2 242 are respectively connected to the corresponding infusion channels 32 in the clamping plate 1 21 and the clamping plate 2 22. The joint connecting body 1 241 and the joint connecting body 2 242 are in a closed and movable connection, and the joint connecting body 1 241 and the joint connecting body 2 242 are in the shape of a sphere that can accommodate hydraulic oil. The structural characteristics of the hemisphere mean that the clamping plate 1 21 and the clamping plate 2 22 can rotate within a range while transmitting hydraulic oil, so as to achieve the purpose of synchronously driving multiple clamping heads 23 when only one injection tube 31 is retained.

[0036] Furthermore, in order to increase the clamping force of the clamping head 23 on the volute from both sides driven by the clamping plate 22, a supporting cylinder 4 is also provided, and the cylinder seat of the supporting cylinder 4 is fixed to the bottom of the base 1, the telescopic rod of the supporting cylinder 4 is fixedly connected to the clamping plate 22, the telescopic rod is slidably placed in the cylinder seat, and the moving path of the telescopic rod of the supporting cylinder 4 fits the rotation path of the clamping plate 22, that is, the slide groove and curvature radius in the cylinder seat, the curvature radius of the telescopic rod moving trajectory, and the curvature radius of the rotation path of the clamping plate 22 are all the same, and a driving unit is provided in the cylinder seat, the driving unit is used to be electrically connected to an external controller, and drive the telescopic rod to slide along the cylinder seat under the action of the external controller.

[0037] When the telescopic rod of the supporting cylinder 4 is fully retracted into the cylinder seat, the tops of the clamping plate 22 and the clamping plate 1 21 are in a coplanar state, thereby reducing the interference of the telescopic rod of the supporting cylinder 4 on the movable range of the clamping plate 22.

[0038] It can be known that a pressure sensor is installed at the end of each clamping head 23, and the pressure sensor is electrically connected to an external controller. When the pressure value applied to the clamping head 23 is too large, the external controller controls the telescopic rod of the supporting cylinder 4 to stop or retract one end to adjust the pressure of the clamping head 23 on the volute.

[0039] In summary, the technical solution of the present application is: utilizing the hydraulic action and the regulating action of the supporting cylinder 4 to drive the clamping plate 1 21 and the clamping plate 2 22 to clamp the outer side of the volute according to the shape of the volute to be clamped. Under the action of hydraulic pressure, a plurality of clamping heads 23 can achieve stable clamping of the volute around, thereby improving the clamping stability of the volute. In addition, the present design has a simple structure and is easy to operate.

[0040] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
