[0028] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0029] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0031] The embodiment of the utility model provides a special fixture for shell milling water nozzle, such as Figure 3-9 As shown, including:

[0032] A positioning mechanism 100, the positioning mechanism 100 comprises a first positioning element 110 for positioning the housing flange 10 and a second positioning element 120 for positioning the housing circular hole 11;

[0033] The fixing mechanism 200 includes a spinning assembly 210 for fixing the bottom surface 12 of the housing;

[0034] The guide and limit mechanism 300 includes two guide elements 310 arranged opposite to each other, and guide wheels 313 are respectively provided on the two guide elements 310. A limit space 320 capable of accommodating the shell is formed between the two guide wheels 313. The length of the limit space 320 is less than the length between the two edges of the shell. The two edges of the shell can respectively abut against the two guide wheels 313 and be inserted into the limit space 320.

[0035] The bottom plate 400 , the positioning mechanism 100 , the fixing mechanism 200 and the guide and limiting mechanism 300 are all arranged on the bottom plate 400 .

[0036] The positioning mechanism 100 is composed of two positioning elements, the first positioning element 110 is used to position the housing flange 10, and the second positioning element 120 is used to position the housing circular hole 11. This design can ensure the accurate position of the housing during the processing and improve the processing accuracy. The fixing mechanism 200 includes a spinning component 210, which is used to fix the bottom surface 12 of the housing, which can ensure the stability of the housing during the milling process of the water nozzle and prevent the processing quality from being affected by vibration or movement.

[0037] The guide elements 310 are designed to be arranged opposite to each other, that is, they are respectively located on both sides of the bottom plate 400, and each guide element is provided with a guide wheel 313, and a limit space 320 is formed between the guide wheels. The length of the limit space 320 is designed to be less than the length between the two edges of the shell. Such a design ensures that when the shell is guided into this space, the two edges of the shell will respectively abut against the two guide wheels 313 and insert into the limit space 320. Since the length of the limit space 320 is less than the length between the two edges of the shell, the shell cannot automatically escape from the limit space 320 without external force. At the same time, the setting of the two guide wheels 313 improves the smoothness of the shell entering the limit space 320. This design provides a self-locking mechanism to ensure the stability and precise position of the shell during processing.

[0038] In some embodiments, the two edges of the shell are guided by the guide element 310. First, the elasticity of the shell can be utilized: the shell can be deformed elastically to temporarily reduce the length between the two edges, thereby adapting to the size of the limited space 320; second, the elasticity of the guide element 310 can be utilized: the guide element 310 can be designed to be retractable to dynamically adjust the length of the limited space 320 to adapt to shells of different sizes. The guide element 310 can include a mechanical structure, such as a spring, a hydraulic or pneumatic system, so that it can be extended or retracted when needed, thereby adapting to shells of different sizes. The size design of the limited space 320 provides a self-locking mechanism to maintain the stable position of the shell without additional fixing elements; through the elastic deformation of the shell or the retractability of the guide element 310, the fixture can adapt to shells of different sizes, increasing its versatility and flexibility; once the shell is correctly placed, due to the self-locking mechanism, the operator does not need additional operations to fix the shell, simplifying the processing process; since the shell enters the limited space 320 through elastic deformation or the retraction of the guide element 310, this reduces the damage that may be caused to the shell during the positioning process.

[0039] The positioning mechanism 100, the fixing mechanism 200 and the guide limiting mechanism 300 are all arranged on the bottom plate 400. The bottom plate 400 serves as the basis of the entire clamp, supporting all components and ensuring the stability and durability of the clamp.

[0040] During the use of the clamp, the housing is first placed according to the positions of the first positioning element 110 and the second positioning element 120. When the housing edge 13 contacts the guide wheel 313, the two edges of the housing are respectively abutted against the guide wheel 313 by the action of external force, so that the housing enters the limited space 320. Finally, the housing is fixed by the fixing mechanism 200 for further processing. The design of this clamp improves the positioning accuracy, stability and convenience of operation during the clamping process, is suitable for automated or semi-automated production lines, and can improve production efficiency and processing quality.

[0041] In some embodiments, the guide element 310 includes a fixing seat 311 , on which a guide portion 312 for cooperating with the edge 13 of the limiting shell to pass through is disposed, and on which a guide wheel 313 is disposed.

[0042] The fixed seat 311 is the supporting part of the guide element 310. It is fixed on the bottom plate 400 and provides a stable base for the entire guide mechanism. The guide part 312 is a protruding part on the fixed seat 311. It has a specific shape or structure and is used to cooperate with the edge of the shell to ensure that the shell will not leave the limit space 320 during the processing process. The function of the guide wheel 313 is to reduce the friction of the shell when passing through the guide element 310, while providing a smooth guiding effect. The design of the guide wheel 313 can be a ball bearing, a roller bearing or other types of bearings to adapt to different load and movement requirements. The guide wheel 313 can reduce the friction between the shell and the guide element 310, reduce wear, and extend the service life of the fixture.

[0043] Furthermore, the fixing seat 311 is provided with a sliding groove 314 matching with the guiding portion 312 . The guiding portion 312 is connected to the fixing seat 311 through an elastic component 315 and slides in the sliding groove 314 .

[0044] The fixed seat 311 is provided with a sliding groove 314 that matches the guide portion 312. The design of this groove allows the guide portion 312 to slide in the fixed seat 311, thereby adapting to shells of different sizes or shapes. The guide portion 312 is connected to the fixed seat 311 through an elastic component 315 and can slide in the sliding groove 314. The elastic component 315 connects the guide portion 312 and the fixed seat 311, providing the necessary elastic force so that the guide portion 312 can be close to the edge 13 of the shell, while allowing the guide portion 312 to slide freely in the sliding groove 314. The elastic component 315 can be a spring, a rubber pad or other types of elastic materials.

[0045] The guide element 310 can adapt to housings of different sizes and shapes through the design of the sliding groove 314 and the elastic component 315, thereby improving the versatility and flexibility of the clamp. The elastic component 315 ensures that the guide portion 312 maintains close contact with the housing edge 13, thereby improving stability during processing.

[0046] Furthermore, the guide portion 312 is provided with a guide groove 316 , and the guide portion 312 is fixed on the fixing seat 311 via a fixing pin 317 passing through the guide groove 316 .

[0047] The guide groove 316 is a groove on the guide portion 312, which provides a passage for the fixing pin 317 to pass through. The fixing pin 317 is a component that passes through the guide groove 316 and fixes the guide portion 312 on the fixing seat 311. The fixing pin 317 can be a metal rod or other types of rigid materials, and its design needs to have sufficient strength to withstand the forces that may be generated during the processing. The cooperation of the guide groove 316 and the fixing pin 317 can ensure the accurate positioning of the guide portion 312 on the fixing seat 311, thereby improving the processing accuracy of the entire fixture.

[0048] In some embodiments, the first positioning element 110 is a limiting column 111 , and a truncated table 112 is disposed on the limiting column 111 .

[0049] The function of the limiting column 111 is to limit the position of the shell flange to ensure that it remains stable during the processing. The limiting column 111 is usually fixed on the base plate 400 and has a certain height and rigidity; the frustum 112 is a part of the limiting column 111, and is a trapezoidal structure with a wider bottom and a narrower top. The design of the frustum 112 can reduce the contact area to reduce damage to the shell.

[0050] In some embodiments, the second positioning element 120 includes a mounting seat 121 and a positioning rod 122 disposed on the mounting seat 121 , and the top of the positioning rod 122 matches the circular hole 11 of the housing.

[0051] The mounting seat 121 is a supporting structure of the second positioning element 120. It is fixed on the base plate 400 and provides a stable base for the positioning rod 122. The design of the mounting seat 121 needs to ensure that it is firmly connected to the base plate 400 to support the stability of the positioning rod 122 during the processing. The positioning rod 122 extends from the mounting seat 121, and its top is designed to match the shell circular hole 11. The positioning rod 122 can be cylindrical or other shapes to adapt to the size and shape of the shell circular hole 11. The top of the positioning rod 122 is designed to fit tightly with the shell circular hole 11, which can be a cylindrical end directly inserted into the circular hole, or has a specific shape to adapt to the contour of the circular hole. This design ensures the position accuracy of the shell during the processing. The tight fit between the top of the positioning rod 122 and the shell circular hole 11 can provide high-precision positioning and reduce processing errors.

[0052] Furthermore, the top of the positioning rod 122 is conical.

[0053] In some embodiments, the spinning assembly 210 includes a spinning rod 211 and a positioning block 212 matched with the spinning rod 211 .

[0054] The function of the spinning rod 211 is to apply pressure to fix the bottom surface 12 of the shell. The positioning block 212 is another part of the spinning assembly 210, which cooperates with the spinning rod 211. The positioning block 212 is usually designed to match the shape and size of the bottom surface 12 of the shell to ensure that the pressure applied by the spinning rod 211 is evenly distributed. The main function of the spinning assembly 210 is to fix the shell to prevent movement or rotation during the processing. Through the cooperation of the spinning rod 211 and the positioning block 212, it can be ensured that the pressure applied to the bottom surface 12 of the shell is uniform, avoiding local overload or deformation.

[0055] Furthermore, the positioning block 212 is provided with a fixing portion 213 in contact with the housing, and the fixing portion 213 is connected to a slope 214 inclined toward the bottom plate 400 .

[0056] The fixing portion 213 is the portion of the positioning block 212 that is in direct contact with the housing, and is generally designed to match the shape and size of the housing bottom surface 12. The surface of the fixing portion 213 may have a texture or a specific shape to increase the friction with the housing to ensure that the housing does not slide or move during processing. The ramp 214 is an inclined portion of the fixing portion 213 connected to the main body of the positioning block 212, which is inclined from the fixing portion 213 toward the bottom plate 400. The inclined design of the ramp 214 can reduce the contact area with the housing and reduce possible damage to the housing during positioning.
