Description

Technical Field

[0001] This utility model belongs to the field of galvanized sheet cutting technology, and in particular relates to a positioning fixture for cutting galvanized sheets. Background Technology

[0002] Galvanized steel sheet is a welded steel sheet with a hot-dip galvanized or electro-galvanized layer on its surface. It is widely used in construction, home appliances, automobiles and ships, container manufacturing, and electromechanical industries.

[0003] In the processing of galvanized steel sheets, they need to be cut. The existing cutting and fixing method is to place the sheet on the workbench and manually rotate the threaded rod to drive the fixing plate to fix the steel sheet. After fixing, the cutting operation is then carried out. This manual fixing and positioning has the disadvantage of slow fixing speed, especially when cutting steel sheets of different sizes, which requires constant adjustment of the fixing spacing. To address this, we propose a positioning fixture that facilitates the adjustment of the fixing spacing to solve the above-mentioned shortcomings. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning fixture for cutting galvanized steel sheets, which has the purpose of conveniently adjusting the fixed spacing, so as to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A positioning fixture for cutting galvanized sheet includes a worktable, a top rod slidably disposed on the inner surface of the worktable, the bottom of the top rod being driven by a drive structure to move the top rod up and down, a support base being fixedly connected to the top of the top rod, a connecting plate being fixedly connected to the top of the support base, a servo motor being fixedly connected to one side of the inner cavity of the connecting plate, a drive gear being fixedly connected to the output end of the servo motor, a hollow cylinder being rotatably connected to the side of the support base away from the bearing sleeve through a bearing sleeve, a threaded cylinder being integrally connected to the side of the cylinder away from the bearing sleeve, a driven gear being fixedly connected to the surface of the threaded cylinder, the surface of the driven gear meshing with the surface of the drive gear, a threaded rod being threadedly connected to the inner surface of the threaded cylinder, the threaded rod penetrating the support base, and a fixing plate being fixedly connected to the opposite side, guide rods being fixedly connected to the front and rear positions of the fixing plate near the support base, the outer surface of the guide rods slidingly penetrating the inner surface of the support base.

[0006] Preferably, a guide cylinder is embedded and fixedly connected inside the worktable at a position corresponding to the push rod, and the inner surface of the guide cylinder is slidably connected to the outer surface of the push rod.

[0008] Preferably, the top of the threaded rod is located at the bottom of the connecting plate, and the length of the threaded rod is greater than the sliding distance of the guide rod on the inner surface of the support.

[0009] Preferably, the support base has a through hole through which the guide rod and the fixing plate slide.

[0010] 1. The beneficial effects of this utility model are: This utility model uses a drive structure to move the top rod up and down, thereby moving the support seat at the top of the top rod up and down, thus satisfying the need to fix plates of different thicknesses. At the same time, when it is necessary to adjust the left and right spacing of the fixation, it is only necessary to drive the active gear to rotate through the servo motor. The rotation of the active gear drives the driven gear to rotate, thereby driving the threaded cylinder connected to its shaft to rotate. At the same time, the cylinder connected to the threaded cylinder rotates in the bearing sleeve, thereby driving the threaded rod connected to its internal thread to rotate, thereby driving the fixing plate to move. Through the limiting sliding of the guide rod, the pressing distance between the two fixing plates can be adjusted, thus facilitating the adjustment of the fixing distance and replacing the manual rotation adjustment method.

[0011] 2. This utility model guides the up-and-down movement of the top rod by setting the outer surface of the top rod to slide on the inner surface of the guide cylinder.

[0012] 3. This utility model uses a servo motor to drive the threaded rod to rotate, which in turn drives the threaded sleeve on the surface of the threaded rod to rotate, thereby driving the connecting cross plate to move up and down, thus providing a drive for the up and down movement of the top rod.

[0013] 4. This utility model provides a through hole to facilitate the passage of the guide rod and the fixing plate, and to allow them to move within the through hole. Attached Figure Description

[0020] In the following description, embodiments of the positioning fixture for cutting galvanized steel sheets according to the present invention will be described with reference to the accompanying drawings.

[0021] Example 1:

[0022] Figure 1-3This invention illustrates a positioning fixture for cutting galvanized steel sheets according to an embodiment of the present invention. It includes a worktable 1, a push rod 2 slidably disposed on the inner surface of the worktable 1, and a guide cylinder 15 embedded and fixedly connected inside the worktable 1 at a position corresponding to the push rod 2. The inner surface of the guide cylinder 15 is slidably connected to the outer surface of the push rod 2. By setting the outer surface of the push rod 2 to slide on the inner surface of the guide cylinder 15, the up-and-down movement of the push rod 2 is guided. The bottom of the push rod 2 is driven by a driving structure 3, which drives the push rod 2 to move up and down. The driving structure 3 includes a connecting plate 31 fixedly connected to the top of the inner cavity of the worktable 1, and a servo motor 32 fixedly connected to the bottom of the connecting plate 31. The output shaft of the servo motor 32 passes through the connecting plate 31. A threaded rod 33 is fixedly connected to the worktable 1. The top of the threaded rod 33 is rotatably connected to the worktable 1 via a bearing seat. A threaded sleeve 34 is threadedly connected to the surface of the threaded rod 33. Connecting horizontal plates 35 are fixedly connected to both sides of the threaded sleeve 34. The top of the connecting horizontal plate 35 is fixedly connected to the bottom of the push rod 2. The threaded rod 33 is rotated by a servo motor 32, which in turn rotates the threaded sleeve 34 on the surface of the threaded rod 33, thereby driving the connecting horizontal plate 35 to move up and down, thus providing drive for the up and down movement of the push rod 2. A support base 4 is fixedly connected to the top of the push rod 2. A connecting plate 5 is fixedly connected to the top of the support base 4. A servo motor 6 is fixedly connected to one side of the inner cavity of the connecting plate 5. A drive gear 7 is fixedly connected to the output end of the motor 6. A hollow cylinder 9 is rotatably connected to the side of the support base 4 away from the bearing sleeve 8. A threaded cylinder 10 is integrally connected to the side of the cylinder 9 away from the bearing sleeve 8. A driven gear 11 is fixedly connected to the surface of the threaded cylinder 10, and the surface of the driven gear 11 meshes with the surface of the drive gear 7. A threaded rod 12 is threadedly connected to the inner surface of the threaded cylinder 10, penetrating the support base 4. A fixing plate 14 is fixedly connected to the opposite side. Guide rods 13 are fixedly connected to the front and rear positions of the fixing plate 14 near the support base 4. The outer surface of the guide rods 13 slides through the inner surface of the support base 4, driving the push rod 2 to move up and down via the drive structure 3. The support seat 4 at the top of the push rod 2 moves up and down to fix plates of different thicknesses. When it is necessary to adjust the left and right spacing of the fixation, the servo motor 6 drives the drive gear 7 to rotate. The rotation of the drive gear 7 drives the driven gear 11 to rotate, which in turn drives the threaded cylinder 10 connected to its shaft to rotate. At the same time, the cylinder body 9 connected to the threaded cylinder 10 rotates in the bearing sleeve 8, which drives the threaded rod 12 connected to its internal thread to rotate, thereby driving the fixing plate 14 to move. Through the limiting sliding of the guide rod 13, the pressing distance between the two fixing plates 14 can be adjusted, thus facilitating the adjustment of the fixing distance and replacing the manual rotation adjustment method.

[0023] Example 2:

[0024] Figure 1-3 This invention illustrates a positioning fixture for cutting galvanized steel sheets according to an embodiment of the present invention. It includes a worktable 1, with a push rod 2 slidably mounted on the inner surface of the worktable 1. The bottom of the push rod 2 is driven by a drive structure 3, causing the push rod 2 to move up and down. A support base 4 is fixedly connected to the top of the push rod 2, and a connecting plate 5 is fixedly connected to the top of the support base 4. A servo motor 6 is fixedly connected to one side of the inner cavity of the connecting plate 5, and a drive gear 7 is fixedly connected to the output end of the servo motor 6. A hollow cylinder 9 is rotatably connected to the side of the support base 4 away from the bearing sleeve 8. A threaded cylinder 10 is integrally connected to the side of the cylinder 9 away from the bearing sleeve 8, and a driven gear 11 is fixedly connected to the surface of the threaded cylinder 10. The surface of wheel 11 meshes with the surface of the drive gear 7. The inner surface of the threaded cylinder 10 is threaded with a threaded rod 12. The top of the threaded rod 12 is located at the bottom of the connecting plate 5, and the length of the threaded rod 12 is greater than the sliding distance of the guide rod 13 on the inner surface of the support base 4. The threaded rod 12 passes through the support base 4, and a fixing plate 14 is fixedly connected to the opposite side. The front and rear positions of the fixing plate 14 near the support base 4 are both fixedly connected with the guide rod 13. The support base 4 has a through hole through which the guide rod 13 and the fixing plate 14 slide. By setting the through hole, it is convenient for the guide rod 13 and the fixing plate 14 to pass through and move within the through hole. The outer surface of the guide rod 13 slides through the inner surface of the support base 4.

[0025] Working principle: When this utility model is in use, the servo motor 2 32 drives the threaded rod 2 33 to rotate, thereby causing the threaded sleeve 34 on the surface of the threaded rod 2 33 to rotate, which in turn causes the connecting horizontal plate 35 to move up and down, thereby causing the top rod 2 to move up and down, and in turn causing the support seat 4 at the top of the top rod 2 to move up and down, thus satisfying the fixing of plates of different thicknesses. At the same time, when it is necessary to adjust the left and right spacing of the fixing, the servo motor 1 6 drives the drive gear 7 to rotate, and the rotation of the drive gear 7 drives the driven gear 11 to rotate, thereby causing the threaded cylinder 10 connected at its shaft to rotate. At the same time, the cylinder body 9 connected to the threaded cylinder 10 rotates in the bearing sleeve 8, thereby causing the threaded rod 12 connected inside to rotate, which in turn causes the fixing plate 14 to move. Through the limiting sliding of the guide rod 13, the pressing distance between the two fixing plates 14 can be adjusted, thus facilitating the adjustment of the fixing distance and replacing the manual rotation adjustment method.
