DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0029] Please refer to Figures 1 to 3, this application provides a technical solution: a positioning fixture for a cylindrical shell, including a fixture base 1, a part assembly 200 detachably installed on the top of the fixture base 1, and a fixture assembly 300 installed on the top of the fixture base 1 for positioning the part assembly 200; through the combined use of the part assembly 200 and the fixture assembly 300 on the top of the fixture base 1, the cylindrical shell parts can be conveniently positioned without affecting the normal processing flow. By matching the outer shape of the cylindrical shell parts, the positioning fixture can play a good role in limiting the outside of them, so that the subsequent processing processes on their upper surfaces and inner side walls can proceed normally, and it can also meet the positioning and processing requirements of other cylindrical shell parts with the same size, effectively improving the practicability of the positioning fixture.

[0030] In this embodiment, the part assembly 200 is a structure for combining into a cylindrical shell part.

[0031] Such as Figure 1 and Figure 2 As shown, the part assembly 200 includes a plurality of cylindrical tubes 201, a plurality of rib strips 202 fixed to the outside of the cylindrical tubes 201, a heightening block 203 fixed to the bottom of the cylindrical tubes 201, and a communication hole 204 opened between the heightening block 203 and the corresponding bottom of the cylindrical tubes 201.

[0032] It should be noted that the top of the cylindrical tube 201 is open, the number of rib strips 202 on the outside of each cylindrical tube 201 is four, and the bottom of the rib strip 202 is a plane, so that the cylindrical tube 201, the heightening block 203 and the corresponding four rib strips 202 can be combined into a cylindrical shell part, and the processing requirement is to process the upper surface and the inner side wall of this part.

[0033] In this embodiment, the fixture assembly 300 is a structure for positioning the part assembly 200.

[0034] Such as Figure 1 , Figure 2 and Figure 3 As shown, the fixture assembly 300 includes a plurality of limit blocks 301 fixed to the top of the fixture base 1, internal thread holes 302 opened on the top of the limit blocks 301, a pressing block 303 attached to the top of the limit blocks 301, a first hexagon socket head cap screw 304 passing through the top of the pressing block 303, a plurality of placement grooves 305 opened on the top of the fixture base 1, a positioning block 306 inserted into the inner side of the placement grooves 305, a second hexagon socket head cap screw 307 passing through the top of the positioning block 306, and a plurality of limit protrusions 308 fixed to the top of the positioning block 306.

[0035] It should be noted that the limiting block 301 is circular, the inner diameter of the communication hole 204 is slightly larger than the diameter of the limiting block 301, and the corresponding limiting block 301 can be inserted, so that the heightening block 203 can move to the outside of the corresponding limiting block 301 through the communication hole 204 to realize the position limitation of the part. The diameter of the pressing block 303 is larger than the diameter of the limiting block 301, and the bottom of the pressing block 303 can abut against the inner bottom wall of the cylindrical barrel 201, so that the pressing block 303 can abut against the inner bottom wall of the cylindrical barrel 201. The bottom of the rib plate 202 can abut against the top of the corresponding positioning block 306. Specifically, when the bottom of the rib plate 202 abuts against the top of the corresponding positioning block 306, the first hexagon socket head cap screw 304 is in the locked state, and the pressing block 303 applies a positioning pressure to the bottom of the cylindrical barrel 201.

[0036] In addition, the first hexagon socket head cap screw 304 can be threadedly connected to the inside of the internal thread hole 302, so that the position of the pressing block 303 can be positioned through the first hexagon socket head cap screw 304, so as to facilitate the pressing block 303 to apply a positioning pressure to the cylindrical barrel 201. The number of the placement grooves 305 is twice the number of the limiting blocks 301. The two corresponding placement grooves 305 are respectively located on the front and back of the corresponding limiting block 301. The positioning block 306 is rectangular, so that the two corresponding positioning blocks 306 can be used for positioning the cylindrical barrel 201.

[0037] At the same time, a plurality of internal thread grooves for the threaded connection of the second hexagon socket head cap screw 307 are provided on the top of the fixture base 1, so that the second hexagon socket head cap screw 307 can be threadedly connected to the corresponding internal thread groove to position the positioning block 306 inside the corresponding placement groove 305. Among them, the internal thread groove is communicated with the inside of the corresponding placement groove 305 to facilitate the normal progress of the connection work. The limiting protrusion 308 is strip-shaped, and the number of the limiting protrusions 308 on the top of each positioning block 306 is two. The limiting protrusion 308 is located on the side of the top of the positioning block 306 away from the corresponding second hexagon socket head cap screw 307. The left and right sides of the rib plates 202 on the front and back can respectively be attached to the opposite sides of the corresponding two limiting protrusions 308, so that the limiting protrusion 308 can play a role in limiting the rib plate 202, thereby further improving the stability after the part is positioned and facilitating the normal progress of the processing work.

[0038] It should also be noted that the outer bottom of the rib plate 202 is square, the height of the limit protrusion 308 does not exceed the square part of the rib plate 202, and the side of the limit protrusion 308 close to the corresponding rib plate 202 is a plane. Thus, after the rib plate 202 and the corresponding two limit protrusions 308 are fitted and limited, through the plane limit between the corresponding two limit protrusions 308, a good limiting effect can be exerted on the rib plate 202, and then a limiting effect on the cylindrical barrel 201 is achieved, so that the cylindrical barrel 201 will not slide when the pressing block 303 is locked, facilitating the normal progress of the pressing and positioning work. And due to the square setting, the height of the limit protrusion 308 only needs to meet the requirement of being able to fit with the outer bottom of the rib plate 202, thus not affecting the normal progress of the upper surface processing work. The fixture assembly 300 is made of aluminum alloy. Aluminum alloy has a low density but a relatively high strength, close to or exceeding high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, and is widely used in industry, with the usage amount second only to steel. It can meet the positioning requirements of parts and has a long service life, and is a commonly used material in existing industrial processing positioning fixtures.

[0039] The working principle of the above embodiment is as follows:

[0040] When machining a machined part, the cylindrical barrel 201 is placed outside the corresponding limit block 301 through the communication hole 204, and the bottom of the rib plate 202 is made to fit with the top of the adjacent positioning block 306, and the rib plate 202 is located between the opposite sides of the corresponding two limit protrusions 308. The pressing block 303 is moved into the interior of the cylindrical barrel 201, and locking is completed through the cooperation between the first inner hexagon bolt 304 and the internal thread hole 302, so as to position the position of the cylindrical barrel 201, facilitating the normal and stable progress of the processing processes on the upper surface and the inner side wall of the cylindrical barrel 201.

[0041] Compared with the prior art, this cylindrical shell positioning fixture, through the combined use of the part assembly 200 and the fixture assembly 300 on the top of the fixture base 1, can conveniently position the cylindrical shell part without affecting the normal processing process. Through the matching of the shape of the cylindrical shell part, the positioning fixture can well limit its outer side, so that the subsequent processing processes on its upper surface and inner side wall can proceed normally, and it can also meet the positioning and processing requirements of other cylindrical shell parts with the same size, effectively improving the practicability of the positioning fixture and solving the defect that the existing positioning fixture cannot effectively meet the positioning and processing requirements of the cylindrical shell part.
