Description

Technical Field

[0001] This utility model relates to the technical field of aluminum rod processing equipment, specifically a quick clamping device for aluminum rod processing. Background Technology

[0002] Aluminum bars are cylindrical rods made of pure aluminum. Aluminum has good machinability, making it easy to cut, join, and shape. This allows aluminum bars to be customized to meet various shapes and sizes. When machining aluminum bars, clamping devices are usually used to hold the workpiece in place to prevent it from shifting.

[0003] Most existing clamping devices use threaded rods to move clamping blocks to clamp workpieces. However, when the movement of the clamping blocks is too long, the threaded rod needs to be rotated many times to move the clamping blocks to the corresponding position, which is time-consuming in use. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a quick clamping device for aluminum rod processing, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick clamping device for aluminum rod processing, comprising a device body, a transmission cavity on the device body, two transmission sliders slidably mounted in the transmission cavity, each transmission slider having a toothed groove on its side closest to each other, a transmission gear rotatably mounted at the center of the transmission cavity and meshing with the toothed groove, both transmission sliders meshing with the transmission gear, two symmetrical rectangular sliding holes on the top inner wall of the transmission cavity, a connecting block protruding from the top of each of the two transmission sliders passing through the rectangular sliding holes and extending to the outside, a movable block mounted on each of the two connecting blocks, two guide rods slidably mounted on the movable blocks, a same movable mounting plate mounted on the same end of the two guide rods, a rubber block mounted on the movable mounting plate, a V-groove on the side of the rubber block away from the movable mounting plate, a buffer spring sleeved on the guide rod, one end of the buffer spring abutting against the movable mounting plate, the other end of the buffer spring abutting against the movable block, a stop block on the end of the guide rod away from the movable mounting plate, a hydraulic cylinder mounted on one side of the device body, the output shaft of the hydraulic cylinder mounted on one of the transmission sliders.

[0008] Preferably, the bottom of the main body of the device has an inspection port that communicates with the transmission cavity, and an inspection cover is provided at the inspection port. The inspection cover is connected to the main body of the device by fixing bolts.

[0009] Preferably, the transmission cavity is provided with two track rods, and two transmission sliders are slidably arranged on the two track rods respectively.

[0010] Preferably, the movable mounting plate has two symmetrical snap-fit ​​grooves, and the rubber block has two symmetrical snap-fit ​​blocks that are adapted to the snap-fit ​​grooves.

[0011] Preferably, the movable block has a docking groove that matches the docking block, and the movable block and the docking block are connected and fixed by connecting bolts.

[0012] Preferably, multiple protrusions are arranged axially at intervals on both inner walls of the V-shaped groove of the rubber block.

[0013] Preferably, the bottom of the device body is provided with four support columns, which are distributed in a matrix at the bottom of the device body.

[0014] Compared with the prior art, this utility model provides a quick clamping device for aluminum rod processing, which has the following beneficial effects: This utility model, through the cooperation of a transmission slider, transmission gear, and movable block, allows for the clamping and fixing of aluminum rods. When needed, a hydraulic cylinder drives one of the transmission sliders in the transmission cavity to slide, and the transmission gear causes the other transmission slider to slide. This brings the two transmission sliders closer together, causing the two movable blocks to move closer together. The movable mounting plate and the rubber block on the movable mounting plate then move closer together, quickly clamping the aluminum rod and improving clamping efficiency. Furthermore, the V-groove on the rubber block increases the contact area with the aluminum rod, thus improving clamping stability. Simultaneously, a buffer spring sleeved on the guide rod allows the movable mounting plate to slide on the movable block after the rubber block contacts the aluminum rod, compressing the buffer spring and buffering the impact force generated during clamping, thereby preventing damage to the aluminum rod surface.

[0024] Please see Figure 1-5A quick-clamping device for aluminum rod processing includes a main body 1. A transmission cavity 15 is provided on the main body 1. Two transmission sliders 20 are slidably installed within the transmission cavity 15. Each of the two transmission sliders 20 has a toothed groove 23 on its side closest to each other. A transmission gear 22, meshing with the toothed groove 23, is rotatably installed at the center of the transmission cavity 15. Both transmission sliders 20 mesh with the transmission gear 22. Two symmetrical rectangular sliding holes 12 are provided on the top inner wall of the transmission cavity 15. Each of the two transmission sliders 20 has a protruding docking block 13 that passes through the rectangular sliding hole 12 and extends to the outside. Each of the three main components is equipped with a movable block 3. Two guide rods 8 are slidably mounted on the movable block 3. The same movable mounting plate 5 is mounted on the same end of the two guide rods 8. A rubber block 10 is mounted on the movable mounting plate 5. A V-groove is provided on the side of the rubber block 10 away from the movable mounting plate 5. A buffer spring 9 is sleeved on the guide rod 8. One end of the buffer spring 9 abuts against the movable mounting plate 5, and the other end of the buffer spring 9 abuts against the movable block 3. A stop block 19 is provided on the end of the guide rod 8 away from the movable mounting plate 5. A hydraulic cylinder 4 is mounted on one side of the main body 1 of the device. The output shaft of the hydraulic cylinder 4 is mounted on one of the transmission sliders 20.

[0025] Through the coordinated arrangement of the transmission slider 20, transmission gear 22, and movable block 3, when it is necessary to clamp and fix the aluminum rod, the hydraulic cylinder 4 drives one of the transmission sliders 20 in the transmission cavity 15 to slide. The transmission gear 22 causes the other transmission slider 20 to slide, which in turn brings the two transmission sliders 20 closer together and drives the two movable blocks 3 to move closer together. This causes the movable mounting plate 5 slidably connected to the movable block 3 and the rubber block 10 on the movable mounting plate 5 to move closer together and quickly clamp the aluminum rod, improving clamping efficiency. The V-shaped groove on the rubber block 10 increases the contact area with the aluminum rod, thereby improving clamping stability. At the same time, the buffer spring 9 sleeved on the guide rod 8 allows the movable mounting plate 5 to drive the two guide rods 8 to slide on the movable block 3 after the rubber block 10 contacts the aluminum rod, compressing the buffer spring 9. This buffers the impact force generated during clamping and avoids damage to the surface of the aluminum rod due to clamping.

[0028] Specifically, in this embodiment, two track rods 18 are provided in the transmission cavity 15, and two transmission sliders 20 are slidably arranged on the two track rods 18 respectively.

[0029] By setting the track rod 18, the transmission slider 20 can slide along the track rod 18, thereby guiding the movement direction of the transmission slider 20 and making the movement process of the transmission slider 20 smoother.

[0030] Specifically, in this embodiment, the movable mounting plate 5 has two symmetrical snap-fit ​​grooves 6, and the rubber block 10 has two symmetrical snap-fit ​​blocks 7 that are adapted to the snap-fit ​​grooves 6.

[0031] The quick assembly and disassembly of the rubber block 10 can be achieved through the cooperation of the snap-fit ​​groove 6 and the snap-fit ​​block 7. After the rubber block 10 is worn to a certain extent, it can be quickly replaced, thereby ensuring the stable clamping of the aluminum rod by the device.

[0032] Specifically, in this embodiment, the movable block 3 is provided with a docking groove 16 that is adapted to the docking block 13, and the movable block 3 and the docking block 13 are connected and fixed by connecting bolts 17.

[0033] Through the cooperation of the docking groove 16, docking block 13 and connecting bolt 17, the movable block 3 and docking block 13 can be quickly disassembled and assembled, which facilitates the positioning, maintenance and upkeep of the movable block 3 and movable mounting plate 5 in the later stage.

[0034] Specifically, in this embodiment, multiple protrusions 11 are arranged axially at intervals on both inner walls of the V-shaped groove of the rubber block 10, which can effectively ensure the clamping stability of the rubber block 10 on the aluminum rod.

[0035] Specifically, in this embodiment, four support columns 2 are protruding from the bottom of the device body 1. The four support columns 2 are distributed in a matrix at the bottom of the device body 1, and the support columns 2 can provide stable support for the device body 1.
