[0024] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0025] like Figure 1-9 As shown, an aluminum shell grooving fixture is characterized by comprising a workbench 1, a positioning component 4 for mounting and positioning the aluminum shell 5, and a plurality of cylinder assemblies 3 for performing grooving operations. A platform 15 is mounted on the workbench 1, the positioning component 4 is mounted in the middle of the platform 15, and a hydraulic cylinder assembly 2 is located below the workbench 1 to lift upwards and cooperate with the positioning component 4 to fix the product. The cylinder assemblies 3 are mounted on the platform 15, a first switch 11 for controlling the hydraulic cylinder assembly 2 is mounted on the workbench 1, and a second switch 12 for controlling the cylinder assembly 3 is mounted on the platform 15.

[0026] Furthermore, the cylinder assembly 2 includes a cylinder fixing plate 13 fixed below the worktable 1, a cylinder positioning rod 24 fixed on the cylinder fixing plate 13, a cylinder assembly 23 located inside the cylinder positioning rod 24, a piston connecting rod 22 installed at the end of the cylinder assembly 23, and a lower push rod 21 connected to the piston connecting rod 22.

[0027] Furthermore, a first positioning hole 14 is provided on the platform 15, and the lower push rod 21 passes through the first positioning hole 14 to act as the positioning component 4.

[0028] Furthermore, the positioning component 4 includes a base plate 41, an outer positioning sleeve 42, and several inner positioning blocks 43. The base plate 41 has a second positioning hole 411 corresponding to the first positioning hole 14. There are three inner positioning blocks 43 in an arc shape, which together form an inner positioning sleeve. The outer positioning sleeve 42 is fitted over the inner positioning sleeve and fixed to the base plate 41. The inner wall of the outer positioning sleeve 42 and the outer wall of the outer positioning sleeve 42 have a certain distance between them. This distance is for the aluminum shell 5 to be installed.

[0029] Furthermore, the outer positioning sleeve 42 has three first pressure groove through holes 421, and the connection between the outer positioning sleeve 42 and the base plate 41 also has three clearance holes 422. Each inner positioning block 43 has a second pressure groove through hole 432 corresponding to the first pressure groove through hole 421. The inner positioning block 43 has feed blocks 431 on its upper and lower sides that can enter the clearance holes 422. When the inner positioning block 43 is pushed open by the lower push rod 21, the feed blocks 431 enter through the clearance holes 422, which can play a positioning role and clamp the aluminum shell 5 at the same time.

[0030] Furthermore, the cylinder assembly 3 comprises three cylinders: a cylinder mounting bracket 31, a grooving cylinder 32, and a punch mounting block 33. The cylinder mounting bracket 31 is fixed to the platform 15. The grooving cylinder 32 is fixed to the cylinder mounting bracket 31, and its output end is connected to the punch mounting block 33. A grooving punch 34 is mounted on the punch mounting block 33, and the grooving punch 34 is aligned with the first grooving through hole 421. When the grooving cylinder 32 is activated, the grooving punch 34 is fed through the first grooving through hole 421 to act on the aluminum shell 5 and then feeds inward to the second grooving through hole 432, completing the grooving. With three cylinder assemblies 3, three grooving stages can be completed in a single operation.

[0031] Furthermore, the first pressure groove through hole 421 on the outer positioning sleeve 42 is located at three equal points on the outer circular surface of the outer positioning sleeve 42, and the output end of the cylinder assembly 3 corresponds to the first pressure groove through hole 421. The cylinder assembly 3 corresponding to the first pressure groove through hole 421 ensures the position of the pressure groove and prevents incorrect pressure groove.

[0032] Furthermore, the upper end of the inner positioning block 43 is thicker than the lower end, and the inner positioning sleeve formed by the inner positioning block 43 has a cylindrical through hole that is smaller at the top and larger at the bottom. The inner wall of this inner positioning block 43 is inclined, and the internal shape of the inner positioning sleeve, in conjunction with the lower push rod 21, can better compress outwards.

[0033] The principle is as follows: place the aluminum shell 5 into the outer positioning sleeve 42, press the aluminum shell 5 with your hand to ensure that the aluminum shell 5 is placed at the bottom of the mold, first step on the first switch 11, the oil cylinder assembly 23 pushes the lower push rod 21 to move upward, thereby driving the inner positioning sleeve to move around through the lower push rod 21 and pressing against the inner wall of the product.

[0034] Then, the second switch 12 is activated, and the grooving cylinder 32 pushes the punch fixing block 33 and the grooving punch 34 to move inward. After contacting the outer wall of the product, they are squeezed inward and cooperate with the inner positioning block 43 to generate a three-section grooving.

[0035] Then turn off the second switch 12, release the first switch 11, and remove the product.

[0036] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0037] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
