Technical Field

[0001] This utility model relates to the field of screw machine technology, specifically a positioning mechanism for screw machines. Background Technology

[0002] In the current application of screw machines, precise product positioning is the cornerstone of achieving efficient and accurate assembly.

[0003] Traditional positioning mechanisms mainly employ a positioning method that uses slotted positioning posts on a positioning plate. This method positions products of fixed specifications by matching the slotted positioning posts with specific parts of the product, thus achieving stable positioning.

[0004] However, when processing products of different specifications, the positioning pin slots cannot match the new products, requiring operators to remove and replace the positioning plates. Existing positioning plates are mostly fixed to the screw-making machine by welding, which causes considerable inconvenience during removal. Welded positioning plates are not only difficult to disassemble, but also prone to damaging the screw-making machine itself during the disassembly process. Utility Model Content

[0005] The purpose of this invention is to provide a positioning mechanism for screw machines, so as to solve the problem mentioned in the background art that replacing the positioning plate is quite troublesome.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0010] Preferably, a slider is provided on one side of the connecting plate, and a groove is provided on the mounting plate corresponding to the slider, with the slider being movably disposed within the groove.

[0011] Preferably, the threaded block is provided with two sets of connecting plates, and a fixing groove is provided between the two sets of connecting plates. A vertical rod is provided at the bottom of the positioning plate, and the vertical rod is movably set in the fixing groove.

[0012] Preferably, a fixing block is provided at the bottom of the vertical rod, and a mounting groove is provided on the mounting plate corresponding to the fixing block. The fixing block is movably disposed in the mounting groove. A limit block is provided on one side of the fixing block, and a limit groove is provided on the mounting plate corresponding to the limit block. The limit block is movably disposed in the limit groove.

[0013] Preferably, the protective component also includes a T-shaped block disposed at the bottom of the protective box, and a T-shaped groove is provided on the mounting plate corresponding to the T-shaped block, and the T-shaped block is movably disposed in the T-shaped groove.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figure 1-7 As shown, this application provides a positioning mechanism for a screw machine, including: a screw machine body 1, a base plate 2 on the screw machine body 1, a positioning plate 3 on the base plate 2, a replacement component on the base plate 2, the replacement component including a mounting plate 4 on the base plate 2, a rotating component 8 on the mounting plate 4, a connecting plate 10 on the mounting plate 4, and a vertical rod 5 at the bottom of the positioning plate 3. The replacement component is used for replacing the positioning plate 3.

[0029] Specifically, such as Figure 5 As shown, the replacement component also includes a lead screw 13 located at one end of the rotating part 8, and the lead screw 13 passes through the mounting plate 4. A threaded block 12 is provided on the outer side of the lead screw 13. By rotating the lead screw 13, the threaded block 12 can be driven to move.

[0030] Specifically, such as Figure 5 As shown, a connecting plate 10 is provided on one side of the threaded block 12, and a connecting groove 14 is provided on the mounting plate 4 corresponding to the connecting plate 10. The connecting plate 10 is movably disposed in the connecting groove 14. Through the movement of the threaded block 12, the connecting plate 10 can be driven to slide into the connecting groove 14.

[0031] Specifically, such as Figure 5 As shown, a slider 15 is provided on one side of the connecting plate 10, and a groove 16 is provided on the mounting plate 4 corresponding to the slider 15. The slider 15 is movably disposed in the groove 16. Through the cooperation of the slider 15 and the groove 16, the movement direction of the connecting plate 10 can be limited.

[0032] Specifically, such as Figure 3 As shown, the threaded block 12 is provided with two sets of connecting plates 10, and a fixing groove 11 is provided between the two sets of connecting plates 10. A vertical rod 5 is provided at the bottom of the positioning plate 3. The vertical rod 5 is movably disposed in the fixing groove 11, and the vertical rod 5 can be firmly fixed by the fixing groove 11.

[0033] Specifically, such as Figure 5 As shown, a fixing block 6 is provided at the bottom of the vertical rod 5, and an installation groove 7 is provided on the mounting plate 4 corresponding to the fixing block 6. The fixing block 6 is movably disposed in the installation groove 7. A limit block 9 is provided on one side of the fixing block 6, and a limit groove 24 is provided on the mounting plate 4 corresponding to the limit block 9. The limit block 9 is movably disposed in the limit groove 24. Through the cooperation of the limit block 9 and the limit groove 24, a guiding function can be played, making it easy for the fixing block 6 to slide into the installation groove 7.

[0034] The mounting plate 4 is provided with a protective component, which includes a protective box 23 on the mounting plate 4, a locking block 21 on the protective box 23, and a locking groove 17 on the mounting plate 4. The protective component is used to protect the rotating part 8.

[0035] Specifically, such as Figure 7 As shown, the protective assembly also includes a T-shaped block 20 disposed at the bottom of the protective box 23. A T-shaped groove 22 is provided on the mounting plate 4 corresponding to the T-shaped block 20. The T-shaped block 20 is movably disposed in the T-shaped groove 22. Through the cooperation of the T-shaped block 20 and the T-shaped groove 22, the movement direction of the protective box 23 can be restricted, thus preventing the protective box 23 from shaking.

[0036] Specifically, such as Figure 6 As shown, a telescopic rod 19 is provided on one side of the T-shaped block 20, and one end of the telescopic rod 19 is provided on the mounting plate 4. An elastic element 18 is provided between the T-shaped block 20 and the mounting plate 4. The elastic element 18 is provided on the outside of the telescopic rod 19. The locking block 21 is movably provided in the locking groove 17. Through the elasticity of the elastic element 18, the protective box 23 can maintain the protective state of the rotating part 8.

[0037] In this embodiment: the rotation of the lead screw 13 can drive the threaded block 12 to move, thereby driving the connecting plate 10 to slide into the connecting groove 14, so that the fixing groove 11 can lock the vertical rod 5, thereby fixing the positioning plate 3, which makes it easy for the staff to quickly disassemble and install the positioning plate 3. Through the elastic force of the elastic element 18, the protective box 23 can cover the rotating part 8 to avoid external factors from affecting the rotating part 8.

[0038] Specifically, when installing the positioning plate 3, the limiting block 9 slides along the limiting groove 24 to guide the fixing block 6 into the installation groove 7, thus pre-positioning the positioning plate 3. By rotating the rotating component 8, the lead screw 13 can be rotated, which in turn drives the threaded block 12 to move, causing the connecting plate 10 to slide into the connecting groove 14. This allows the fixing groove 11 to lock the vertical rod 5, thus fixing the positioning plate 3. This facilitates quick disassembly and installation of the positioning plate 3 by the workers. After installation, the elastic force of the elastic component 18 can drive the protective box 23 to move towards the rotating component 8, thus covering the rotating component 8 and protecting it. The cooperation between the locking block 21 and the locking groove 17 can remove the protective box 23 from the rotating component 8 when it is necessary to rotate the rotating component 8, effectively preventing the protective box 23 from obstructing the rotation of the rotating component 8.
