Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to a positioning fixture for aluminum profile processing. Background Technology

[0002] Aluminum profiles refer to alloy materials made primarily of aluminum, with the addition of other alloying elements such as copper, magnesium, manganese, silicon, and zinc. These alloys are then processed through extrusion, casting, and other processes to create industrial profiles with specific cross-sectional shapes and dimensions. Aluminum profiles are widely used in the construction, transportation, electronics, and machinery manufacturing industries.

[0003] During the processing of aluminum profiles, various operations such as cutting, drilling, and milling are required. Currently available positioning fixtures for aluminum profile processing are difficult to adapt to aluminum profiles of different shapes. Because the drive mechanism and the chuck are fixedly connected, they can only clamp and position aluminum profiles with one type of cross section, resulting in poor flexibility. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning fixture for aluminum profile processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning fixture for aluminum profile processing includes a worktable and a chuck. Telescopic cylinders are fixedly installed at both ends of the worktable. A connecting block is installed at the movable end of the telescopic cylinder. A bearing is embedded in the connecting block. The movable end of the telescopic cylinder is fixedly connected to the bearing. A plug is fixedly installed at the other end of the connecting block. A plug sleeve is slidably sleeved on the outside of the plug.

[0007] The clamp has a hole and a rotating groove on one side, which are connected to each other. Slot 1 is provided on both sides of the inner wall of the hole, which is connected to the rotating groove. Slot 2 is provided on the other two sides of the inner wall of the hole, and a magnet is fixedly installed in slot 2.

[0008] In addition, the preferred structure is that limit blocks are fixedly installed on both sides of one end of the insertion post, and sliding grooves are opened on both sides of the outer wall of the insertion post. After the insertion post passes through the hole groove, it enters the rotating groove, and the limit blocks are locked in the rotating groove.

[0009] In addition, a preferred structure is that insert strips are provided on both sides of the inner wall of the sleeve, and the insert strips slide within the second groove.

[0010] In addition, a preferred structure is that iron blocks are provided on both sides of the outer wall of the socket, the iron blocks are inserted into the slot 2, and the iron blocks are attracted to the magnet block, and push blocks are provided on both sides of the outer wall of one end of the socket.

[0011] In addition, a preferred structure is that a set of sliding grooves is provided at both ends of the worktable, and a strip groove is provided on the worktable between the two sets of sliding grooves, and the strip groove is connected to the two sets of sliding grooves.

[0012] In addition, a preferred structure is that both ends of the bottom of the chuck are provided with sliders, and the sliders slide within the groove.

[0013] The beneficial effects of this utility model are as follows:

[0025] 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.

[0026] Reference Figure 1-9 A positioning fixture for aluminum profile processing includes a worktable 1 and a chuck 3. Telescopic cylinders 2 are fixedly installed at both ends of the worktable 1. A connecting block 4 is installed at the movable end of the telescopic cylinder 2. A bearing 41 is embedded in the connecting block 4. The movable end of the telescopic cylinder 2 is fixedly connected to the bearing 41. A plug 6 is fixedly installed at the other end of the connecting block 4. A plug sleeve 5 is slidably sleeved on the plug 6.

[0027] The clamp 3 has a hole 32 and a rotating groove 33 on one side, and the hole 32 and the rotating groove 33 are connected. The inner wall of the hole 32 has slot 1 321 on both sides, and slot 1 321 is connected to the rotating groove 33. The inner wall of the hole 32 has slot 2 322 on the other two sides, and a magnet block 7 is fixedly installed in slot 2 322.

[0028] Meanwhile, limit blocks 61 are fixedly installed on both sides of one end of the insertion post 6, and sliding grooves 62 are opened on both sides of the outer wall of the insertion post 6. After the insertion post 6 passes through the hole groove 32, it enters the rotating groove 33. The limit block 61 is stuck in the rotating groove 33, so that the insertion post 6 cannot be pulled out horizontally.

[0029] Furthermore, insert strips 53 are provided on both sides of the inner wall of the insert 5, and the insert strips 53 slide within the slide groove 62 to facilitate the movement of the insert 5.

[0030] Meanwhile, iron blocks 51 are provided on both sides of the outer wall of the sleeve 5. The iron blocks 51 are inserted into the slot 2 322 and are attracted to the magnet block 7. Push blocks 52 are provided on both sides of the outer wall of one end of the sleeve 5, so that the sleeve 5 cannot be rotated, and thus the insert 6 cannot be rotated, thereby firmly installing the clamp 3 on the movable end of the telescopic cylinder 2.

[0031] Meanwhile, a set of sliding grooves 11 are provided at both ends of the workbench 1, and a strip groove 12 is provided on the workbench 1 between the two sets of sliding grooves 11. The strip groove 12 is connected to the two sets of sliding grooves 11, which facilitates the installation and removal of the chuck 3.

[0032] Furthermore, both ends of the bottom of the chuck 3 are provided with sliders 31, which slide within the groove 11, making the clamping movement of the chuck 3 more stable.

[0033] In this embodiment, when encountering an aluminum profile that is not compatible with the chuck 3, the push block 52 is pushed outward to move the insert 5. After the iron block 51 separates from the magnet block 7, it leaves the slot 2 322. Then the connecting block 4 is rotated 90 degrees. At this time, the insert 51 will rotate synchronously. One end of the insert 51 rotates 90 degrees in the rotating groove 33. The limiting block 61 will rotate synchronously and align with the slot 1 321. Then the chuck 3 is pushed inward to move on the worktable 1. The limiting block 61 separates from the chuck 3 through the slot 1 321 under the movement of the chuck 3. At this time, the chuck 3 is pushed to move until the slider 31 at the bottom of the chuck 3 enters the strip groove 12. Then the chuck 3 is pulled upward to remove the chuck 3.

[0034] Next, vertically insert the slider 31 of the new chuck 3 into the strip groove 12, then slide it into the first slide groove 11. Continue to push the chuck 3, and the limiting block 61 will enter the rotating groove 33 through the first slot 321. Then rotate the connecting block 4 90 degrees, driving the insert 6 to rotate synchronously, so that the limiting block 61 rotates synchronously 90 degrees and is locked in the rotating groove 33, unable to be pulled out horizontally. Then push the push block 52 inward, insert the iron block 51 into the second slot 322 and attract it to the magnet block 7, thus completing the replacement of the chuck 3. Then place the aluminum profile on the workbench 1, start the telescopic cylinder 2, drive the chuck 3 to move, and then clamp and position the aluminum profile.

[0035] In this utility model, the clamp 3 and the telescopic cylinder 2 are detachably installed. When encountering aluminum profiles with different cross-sections, the clamp 3 can be quickly removed from the movable end of the telescopic cylinder 2, and a clamp 3 that is compatible with the aluminum profile can be installed to clamp and position the aluminum profile. It can be adapted to aluminum profiles with different cross-sections and has strong flexibility.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
