[0002] Aluminum products are made of aluminum and other alloy elements. Usually, they are first processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then made through processes such as cold bending, sawing, drilling, assembly, and coloring. For example, the patent document with application number CN202020012908.5 discloses an adjustable precision hole opening device for the production and processing of aluminum alloy furniture aluminum materials. By setting a distance adjustment mechanism, the distance between each drill hole can be well controlled to achieve drilling at a certain distance, and the distance between each drill hole can be accurately controlled.

[0003] However, in similar solutions mentioned above, when the drill bit is drilling holes in aluminum, the aluminum is squeezed by the drill bit, causing the position of the aluminum to shift, resulting in inaccurate drilling positions, and the drill bit is only fixed by threads. After long-term use, the threads are worn, resulting in unstable connections, and the installation operation is cumbersome, increasing the burden on personnel.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an aluminum processing drill bit that is easy to fix is ​​proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an aluminum processing drill bit that is easy to fix, which solves the above-mentioned similar solutions proposed in the above-mentioned background technology. When the drill bit is drilling holes in aluminum, the aluminum is squeezed by the drill bit, which causes the position of the aluminum to shift, resulting in inaccurate drilling position, and the drill bit is only fixed by threads. After long-term use, the threads are worn, resulting in unstable connection, and the installation operation is cumbersome, which increases the burden on personnel.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aluminum processing drill bit that is easy to fix, comprising a support frame, a fixing assembly and a buckling assembly, the lower end surface of the support frame is surrounded by four groups of fixing blocks, and the fixing assembly is located at the lower end surface of the support frame, and the fixing assembly comprises a telescopic rod, a supporting spring, a fixing ring and a rubber belt, the telescopic rod is fixed below the four groups of fixing blocks, and the supporting spring is fixed on the inner side of the telescopic rod, and the fixing ring is fixed at the lower end of the telescopic rod, the rubber belt is wrapped around the outer side of the fixing ring, and a drill bit is arranged at the center of the lower end of the support frame, and the buckling assembly is located below the support frame, the buckling assembly comprises a supporting column, a supporting block, a connecting rod and a limiting protrusion, and the upper end of the drill bit is slidably connected to the supporting column, and the lower end of the supporting column is provided with the supporting block, four groups of connecting rods are arranged around the outer side of the supporting block, and the limiting protrusion is hinged at one end of the connecting rod away from the supporting block.

[0007] Furthermore, the telescopic rod and the supporting spring are equidistantly arranged on the upper end of the fixing ring, and the fixing ring forms a lifting structure through the telescopic rod.

[0008] Furthermore, a threaded protrusion is fixed on the upper end of the drill bit, and a threaded ring is threadedly connected to the outer side of the threaded protrusion.

[0009] Furthermore, a support cover is provided at the upper end of the threaded ring, and the upper end surface of the threaded ring is fitted with the lower end surface of the support cover.

[0010] Furthermore, the connecting rod is hinged with the supporting block and the limiting protrusion to form a rotating structure, and a return spring is fixed at the center of the lower end of the supporting block.

[0011] Furthermore, four groups of the limiting protrusions are provided, and a slide groove is fixed on the outer side of the support column, and the height of the support column is higher than the height of the slide groove.

[0012] The utility model provides an aluminum material processing drill bit which is easy to fix and has the following beneficial effects:

[0013] The aluminum material can be fixed before the drill bit approaches the aluminum material, thereby preventing the aluminum material from being squeezed by the drill bit and causing the position of the aluminum material to shift, which can improve the accuracy of drilling. In addition, by adding a fixing component, it can avoid unstable connection after thread wear, and can simplify the installation steps and reduce the burden on personnel during replacement. The specific contents are as follows:

[0014] Before the drill bit drills downward, the fixing ring contacts the aluminum plate first, and through the friction between the fixing ring and the rubber belt, the aluminum plate can be prevented from shifting during drilling. As the drill bit moves downward, the telescopic rod contracts. When installing the drill bit, the drill bit is inserted into the support cover and the support column is squeezed at the same time, so that the connecting rod rotates along the hinge and the limiting protrusion is pushed out, so that the drill bit is clamped by the threaded ring and the support cover, thereby fixing the drill bit.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figures 1 to 4As shown, a drill bit for processing aluminum material that is easy to fix includes a support frame 1, a fixing assembly 3 and a buckle assembly 7. Four groups of fixing blocks 2 are arranged around the lower end surface of the support frame 1 to fix the buckle assembly 7 to improve the stability of the fixing assembly 3. The fixing assembly 3 is located at the lower end surface of the support frame 1, and the fixing assembly 3 includes a telescopic rod 301, a supporting spring 302, a fixing ring 303 and a rubber belt 304. The telescopic rod 301 is fixed below the four groups of fixing blocks 2, and the inner side of the telescopic rod 301 is fixed with a supporting spring 302. The supporting spring 302 makes the telescopic rod 301 automatically extend when no force is applied, and the multiple groups of telescopic rods 301 can improve the uniformity of the force applied to the aluminum plate, and the telescopic rod 301 A fixing ring 303 is fixed to the lower end of the device, which can increase the contact area between the fixing component 3 and the aluminum plate, thereby further improving the stability of the device. The telescopic rod 301 and the support spring 302 are equidistantly arranged at the upper end of the fixing ring 303. Because the fixing ring 303 forms a lifting structure through the telescopic rod 301, it can contact the aluminum material before the drill bit approaches the aluminum material through the fixing ring 303, and press the plate through the support spring 302, thereby avoiding the aluminum material being squeezed by the drill bit and causing the aluminum material position to shift, which can improve the accuracy of punching. A rubber belt 304 is wrapped around the outside of the fixing ring 303, which can further increase the friction between the fixing ring 303 and the aluminum plate, thereby preventing the aluminum plate from sliding.

[0022] A threaded protrusion 41 is fixed to the upper end of the drill bit 4, and a threaded ring 6 is threadedly connected to the outer side of the threaded protrusion 41, and the threaded ring 6 is screwed together with the threaded protrusion 41, so as to quickly fix the drill bit 4. A support cover 5 is provided on the upper end of the threaded ring 6, and the support cover 5 is used to protect the buckle assembly 7. Because the upper end surface of the threaded ring 5 is in contact with the lower end surface of the support cover 5, the position of the drill bit 4 and the threaded ring 6 can be limited, so as to prevent the drill bit 4 from loosening when rotating, and the lower end surface of the support frame 1 A drill bit 4 is arranged at the center of the end, and the buckle assembly 7 is located below the support frame 1. The buckle assembly 7 includes a support column 701, a support block 702, a connecting rod 703 and a limiting protrusion 704. The upper end of the drill bit 4 is slidably connected with the support column 701. The limiting protrusion 704 is provided with four groups, and a slide groove 42 is fixed on the outer side of the support column 701 for placing the support column 701. Because the height of the support column 701 is higher than the height of the slide groove 42, when the drill bit 4 is installed, it can be moved to the The support column 701 is pressed downward to make the support column 701 slide on the inner wall of the slide groove 42, and a support block 702 is arranged at the lower end of the support column 701, and four groups of connecting rods 703 are arranged around the outer side of the support block 702. Because the connecting rod 703 is hinged with the support block 702 and the limiting protrusion 704 to form a rotating structure, the support block 702 is lowered, thereby driving the connecting rod 703 to rotate, so that the limiting protrusion 704 protrudes from the drill bit 4, and the position of the drill bit 4 is further limited by the protrusion of the limiting protrusion 704, which can avoid unstable connection after thread wear, and is conducive to further strengthening the stability of the drill bit 4 fixation, and the connecting rod 703 is hinged to the limiting protrusion 704 at one end away from the support block 702, and a return spring 721 is fixed at the center of the lower end of the support block 702, which is used to restore the return spring 721 from a compressed state before the drill bit 4 is pulled out, so that the limiting protrusion 704 retracts, thereby facilitating the direct pulling out of the drill bit 4, which is conducive to the rapid disassembly of the drill bit 4.

[0023] In summary, when using this kind of aluminum processing drill bit that is easy to fix, first, insert the drill bit 4 into the support cover 5 and the threaded ring 6 until the upper end of the support column 701 contacts the support frame 1, and squeeze the support column 701 and the support block 702 downward, thereby driving the four groups of connecting rods 703 to rotate along the two hinges until the connecting rods 703 are in a parallel state. At this time, the limiting protrusion 704 slides outward and protrudes the drill bit 4. At this time, the lower end of the limiting protrusion 704 abuts against the inner wall of the support cover 5, and at the same time, the threaded ring 6 is tightened so that the upper end of the threaded ring 6 abuts against the outer wall of the support cover 5, thereby fixing the drill bit 4. When processing the aluminum plate, the drill bit 4 moves downward, the fixing ring 303 first contacts the aluminum plate, and moves downward with the device, so that the aluminum plate and the fixing ring 303 are relatively still, and at the same time, the telescopic rod 301 contracts inward and compresses the spring 302, so that the fixing component 3 can press the aluminum plate.
