Description

Technical Field

[0001] This utility model relates to the field of aluminum profile cutting technology, specifically to an auxiliary fixture for aluminum profile cutting. Background Technology

[0002] Aluminum profile cutting is one of the methods of profile processing. In some precision applications, aluminum profiles need to meet strict dimensional accuracy requirements. Since the beginning and end parts are prone to dimensional deviations during processing, cutting is necessary to ensure the overall dimensional accuracy of the aluminum profile. During the cutting process, aluminum profile auxiliary fixtures are usually used to ensure the stability of the cutting.

[0003] However, some aluminum profile auxiliary fixtures can only fix plate-shaped aluminum profiles. When dealing with strip-shaped aluminum profiles, it is inconvenient to fix them, which leads to the limitation of the use of auxiliary fixtures. Therefore, they do not meet the existing needs. In response, we have proposed an aluminum profile cutting auxiliary fixture. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary fixture for cutting aluminum profiles, so as to solve the problem that the auxiliary fixtures for cutting aluminum profiles mentioned in the background art can only fix plate-shaped aluminum profiles. When dealing with strip-shaped aluminum profiles, it is inconvenient to fix them, which leads to the limitation of the use of auxiliary fixtures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary fixture for cutting aluminum profiles, including a worktable. Symmetrical strip holes are provided on both sides of the upper end of the worktable. Slider blocks are slidably connected inside the two strip holes. The upper ends of the two sliders extend through to the outer side of the upper end of the strip holes and are fixedly connected to a clamping plate. A through hole is provided inside the clamping plate. Sliding grooves are provided on both sides of the inner wall of the through hole. A pressure block is slidably connected between the two sliding grooves. The bottom ends of the two sliders extend through to the outer side of the bottom end of the worktable and are fixedly connected to a T-shaped plate.

[0006] Preferably, symmetrical slide rails are fixedly connected to the ends of the two strip holes that are close to each other and to the bottom of the worktable. Each slide rail has a sliding seat slidably connected to its outer surface, and the bottom of each sliding seat is hinged to one end of the T-shaped plate with a connecting rod.

[0007] Preferably, both sides of the bottom end of the workbench are fixedly connected to a fixing plate, the middle of the bottom end of the T-shaped plate is fixedly connected to a connecting plate, and a first threaded rod is fixedly connected to the side of the connecting plate near the fixing plate, and one end of the first threaded rod movably passes through the fixing plate and extends to the outside of the fixing plate.

[0008] Preferably, a spring is fixedly connected between the fixing plate and the connecting plate on the side of the fixing plate close to the connecting plate, and the spring is wound around the outer surface of the first threaded rod.

[0009] Preferably, the fixing plate is located on the side away from the connecting plate and is threaded with a nut on the outer surface of the first threaded rod.

[0010] Preferably, the bottom end of the pressure block is provided with a trapezoidal groove, and the upper end of the pressure block is rotatably connected to a second threaded rod through a rotating shaft. The upper end of the second threaded rod is threaded through a through hole and extends to the top of the clamping plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model involves pulling the first threaded rods on both sides, causing the two first threaded rods to drive the T-shaped plates to move smoothly along the slide rail through the hinge of the connecting rod and the slide block, and to move away from each other. The clamping plates on both sides are also moved away from each other through the connection of the slider and the T-shaped plates. At this time, the aluminum profile is placed on the upper end of the workbench and placed between the two clamping plates. Then, the pulling of the first threaded rods is released. At this time, the two T-shaped plates are driven by the elasticity of the springs to move the clamping plates closer to each other, thereby clamping according to the size of the aluminum profile. Finally, the nut is rotated so that the nut thread rotates on the outer surface of the first threaded rod and moves close to the fixed plate, thereby fixing the position of the clamping plates and avoiding instability in the cutting of the aluminum profile.

[0013] 2. This utility model adjusts the distance between two clamping plates according to the length of the strip aluminum profile, then passes the strip aluminum profile through the two through holes in sequence and places it under the pressure block. Then, the second threaded rod is rotated so that the second threaded rod passes through the clamping plate and rotates to the upper end of the pressure block, thereby pushing the pressure block down along the sliding groove and abutting against the strip aluminum profile, thus pressing and fixing the strip aluminum profile. In addition, the trapezoidal groove opened at the bottom of the pressure block can be used to fix the circular strip aluminum profile according to its diameter. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 An embodiment of this utility model provides an aluminum profile cutting auxiliary fixture, including a workbench 1. Symmetrical strip holes 101 are provided on both sides of the upper end of the workbench 1. Slider 3 is slidably connected inside the two strip holes 101. The upper ends of the two sliders 3 extend through to the outer side of the upper end of the strip holes 101 and are fixedly connected to a clamping plate 2. The clamping plate 2 has a through hole 201 inside. Sliding grooves 20101 are provided on both sides of the inner wall of the through hole 201. A pressure block 13 is slidably connected between the two sliding grooves 20101. The bottom ends of the two sliders 3 extend through to the outer side of the bottom end of the workbench 1 and are fixedly connected to a T-shaped plate 4.

[0021] Two strip holes 101 are fixedly connected to symmetrical slide rails 5 at their front and rear ends, and at the bottom of the worktable 1. Each slide rail 5 has a slide block 6 slidably connected to its outer surface. The bottom end of each slide block 6 is hinged to one end of the T-shaped plate 4 with a connecting rod 7. Fixed plates 8 are fixedly connected to both sides of the bottom of the worktable 1. A connecting plate 9 is fixedly connected to the middle of the bottom of the T-shaped plate 4. A first threaded rod 10 is fixedly connected to the side of the connecting plate 9 near the fixed plate 8. One end of the first threaded rod 10 movably passes through the fixed plate 8 and extends to the outside of the fixed plate 8. A spring 11 is fixedly connected between the side of the fixed plate 8 near the connecting plate 9 and the connecting plate 9. The spring 11 is wrapped around the outer surface of the first threaded rod 10.

[0022] By pulling the first threaded rods 10 on both sides, the two first threaded rods 10 drive the T-shaped plate 4 to move smoothly along the slide rail 5 through the hinge of the connecting rod 7 and the slide block 6, and move away from each other. The clamping plates 2 on both sides are also moved away from each other through the connection of the slider 3 and the T-shaped plate 4. At this time, the aluminum profile of the plate is placed on the upper end of the workbench 1 and placed between the two clamping plates 2. Then, the pulling of the first threaded rods 10 is released. At this time, the two T-shaped plates 4 are driven by the elastic action of the spring 11 to move the clamping plates 2 closer to each other, so as to clamp according to the size of the aluminum profile of the plate.

[0023] The fixing plate 8 is located on the side away from the connecting plate 9, and a nut 12 is threadedly connected to the outer surface of the first threaded rod 10. By rotating the nut 12, the nut 12 is threaded to rotate on the outer surface of the first threaded rod 10 and close to the fixing plate 8, thereby fixing the position of the clamping plate 2 and avoiding instability in the cutting of aluminum profiles.

[0024] The bottom end of the pressure block 13 is provided with a trapezoidal groove 1301. The upper end of the pressure block 13 is rotatably connected to a second threaded rod 14 via a rotating shaft. The upper end of the second threaded rod 14 is threaded through the through hole 201 and extends to the top of the clamping plate 2. The distance between the two clamping plates 2 is adjusted according to the length of the strip aluminum profile. Then, the strip aluminum profile is passed through the two through holes 201 in sequence and placed below the pressure block 13. Then, the second threaded rod 14 is rotated so that the second threaded rod 14 is threaded through the clamping plate 2 and rotates at the upper end of the pressure block 13, thereby pushing the pressure block 13 down along the sliding groove 20101 and abutting against the strip aluminum profile, thereby pressing and fixing the strip aluminum profile. The trapezoidal groove 1301 at the bottom end of the pressure block 13 can be used to fix the diameter of the circular strip aluminum profile.

[0025] When using the aluminum profile cutting auxiliary fixture, by pulling the first threaded rods 10 on both sides, the two first threaded rods 10 drive the T-shaped plate 4 to move smoothly along the slide rail 5 through the hinge of the connecting rod 7 and the slide block 6, and move away from each other. The clamping plates 2 on both sides are also moved away from each other through the connection of the slider 3 and the T-shaped plate 4. At this time, the plate-shaped aluminum profile is placed on the upper end of the workbench 1 and placed between the two clamping plates 2. Then, the pulling of the first threaded rods 10 is released. At this time, the two T-shaped plates 4 are driven by the elastic action of the spring 11 to move the clamping plates 2 closer to each other, thereby clamping according to the size of the plate-shaped aluminum profile. Finally, the nut 12 is rotated so that the nut 12 thread rotates on the outer surface of the first threaded rod 10 and moves close to the fixed plate 8, thereby fixing the position of the clamping plate 2 and avoiding instability in the cutting of aluminum profile.

[0026] When it is necessary to fix the strip aluminum profile, adjust the distance between the two clamping plates 2 according to the length of the strip aluminum profile, then pass the strip aluminum profile through the two through holes 201 in sequence and place it under the pressure block 13. Then rotate the second threaded rod 14 so that the second threaded rod 14 threaded through the clamping plate 2 and rotates to the upper end of the pressure block 13, thereby pushing the pressure block 13 to move down along the slide groove 20101 and abut against the strip aluminum profile, thereby pressing and fixing the strip aluminum profile. The trapezoidal groove 1301 opened at the bottom of the pressure block 13 can be used to fix the circular strip aluminum profile according to its diameter.
