A worktable is provided at the bottom of the inner cavity of the drilling frame, and a drilling platform is movably mounted on the worktable. A first mounting block and a second mounting block are fixedly connected to the top two sides of the worktable, respectively. A rotary motor is mounted on the side of the first mounting block away from the second mounting block. The output end of the rotary motor passes through the first mounting block and is fixedly connected to a lead screw. One end of the lead screw passes through the drilling platform and connects to the second mounting block. The fixing mechanism is symmetrically arranged on both sides of the top of the drilling platform. The fixing mechanism includes a vertical rod fixedly connected to the drilling platform, a crossbeam fixedly connected to the top of the vertical rod, a telescopic rod fixedly connected to the bottom of the crossbeam, a pressing plate fixedly connected to the end of the telescopic rod away from the crossbeam, and a locking spring sleeved on the outside of the telescopic rod. This utility model makes drill bit replacement simple and quick, and can also fix the workpiece, improving processing accuracy.
[0004] However, drill bits are installed and removed using bolts. After prolonged use, these bolts become difficult to remove manually, requiring the use of external tools for disassembly, which is cumbersome. Furthermore, installation also necessitates enhanced stability of the drill bit. Therefore, addressing and refining these issues is a pressing problem that needs to be solved. Utility Model Content
[0005] The purpose of this utility model is to provide a drill bit for a drilling machine that is easy to disassemble, in order to solve the problem mentioned in the background art that bolts are difficult to disassemble manually after long-term use, and therefore require the use of external tools for disassembly, which is troublesome. At the same time, it is also necessary to enhance the fixation of the drill bit during installation.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a drill bit for a drilling machine that is easy to disassemble, including a connecting ring, an mounting cylinder installed on the right side of the connecting ring, a disassembly component installed on the top surface of the mounting cylinder, and an installation component installed inside the mounting cylinder;
[0007] The mounting assembly includes a mounting post, with insertion holes on both the upper and lower surfaces of the mounting post. An elastic retractable post is installed inside the insertion hole, and a mounting ball is installed on the top surface of the elastic retractable post. The outer surface of the mounting post is provided with a matching thread.
[0008] Preferably, the mounting post is installed inside the mounting cylinder via a matching thread, and a mounting pad is fixedly connected to the right side of the mounting post.
[0009] Preferably, a stabilizing ring is installed on the right side of the mounting pad, and the drill bit body is fixedly connected to the right side of the stabilizing ring.
[0010] Preferably, the disassembly assembly includes an adapter tube, which is mounted on the upper and lower surfaces of the mounting tube and is mutually adapted to the insertion hole.
[0011] Preferably, a pressing post is inserted and installed inside the adapter cylinder, and a positioning ring is installed on the inner side wall of the adapter cylinder, the positioning ring and the pressing post being mutually adapted.
[0012] Preferably, an elastic telescopic cylinder is installed on the top surface of the positioning ring, an anti-collision spring is installed inside the elastic telescopic cylinder, and an anti-collision head is fixedly connected to the lower end surface of the pressing column.
[0013] Preferably, the mounting pad and the stabilizing ring are both equipped with reinforcing side plates on their front and rear surfaces. The reinforcing side plates have threaded grooves inside, and threaded posts are threaded inside the threaded grooves. An abutment pad is installed on the back of the threaded posts. An adapter groove is provided on the back of the reinforcing side plates, and the adapter groove and the abutment pad are mutually adapted.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This drilling machine uses a drill bit that is easy to disassemble. During installation, the mounting ball is first squeezed to allow the mounting post to enter the interior of the mounting cylinder. Then, the mounting post is rotated so that the mating thread is installed with the inner thread of the mounting cylinder. When the mounting pad abuts against the right side of the mounting cylinder, the mounting ball enters the interior of the mating cylinder. At this point, the mounting post and the drill bit body can be installed quickly and efficiently. The mounting pad is elastic and is stably clamped between the mounting cylinder and the stabilizing ring under compression, thus facilitating the quick installation of the drill bit body. The fit between the elastically contracting post, the mounting ball, and the mating cylinder provides a positioning effect when installing the mounting post.
[0016] 2. This drilling machine uses easily disassembled drill bits. During disassembly, the two sets of pressing columns are manually pressed. This causes the pressing columns to move the positioning ring downwards, which in turn moves the contact head downwards to contact the top surface of the mounting ball. The pressure from the contact head compresses and retracts the mounting ball and the elastic contraction column, causing them to detach from the adapter cylinder. Rotating the mounting column then causes the mounting ball to contact the inner wall of the mounting cylinder, allowing for quick disassembly. This makes disassembly convenient. Furthermore, after the pressing head removes the pressure from the elastic contraction column and mounting ball, the elastic cylinder automatically returns to its original position. Therefore, the overall operation is quite convenient. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-5 One embodiment provided by this utility model:
[0025] A drill bit for a drilling machine that is easy to disassemble. The elastic shrink column 6 and elastic telescopic cylinder 13 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. It includes a connecting ring 1, an installation cylinder 2 installed on the right side of the connecting ring 1, a disassembly component installed on the top surface of the installation cylinder 2, and an installation component installed inside the installation cylinder 2.
[0026] The mounting assembly includes a mounting post 3, with insertion holes 5 on both its upper and lower surfaces. An elastic retractable post 6 is installed inside each insertion hole 5, and a mounting ball 7 is mounted on the top surface of the elastic retractable post 6. The outer surface of the mounting post 3 is provided with a matching thread 4. The mounting post 3 is installed inside the mounting cylinder 2 via the matching thread 4. A mounting pad 8 is fixedly connected to the right side of the mounting post 3. A stabilizing ring 9 is installed to the right side of the mounting pad 8, and a drill bit body 10 is fixedly connected to the right side of the stabilizing ring 9. During installation, the mounting ball 7 is first squeezed to allow the mounting post 3 to enter the interior of the mounting cylinder 2. Then, the mounting post 3 is rotated so that the adapter thread 4 is threaded into the inner wall of the mounting cylinder 2. When the mounting pad 8 abuts against the right side of the mounting cylinder 2, the mounting ball 7 enters the interior of the adapter cylinder 11. At this point, the mounting post 3 and the drill bit body 10 can be installed quickly and efficiently. The mounting pad 8 is elastic and is stably clamped between the mounting cylinder 2 and the stabilizing ring 9 under compression, thus facilitating the quick installation of the drill bit body 10. The fit between the elastically contracting post 6, the mounting ball 7, and the adapter cylinder 11 provides a positioning effect when installing the mounting post 3.
[0027] The disassembly assembly includes an adapter cylinder 11, which is installed on the upper and lower surfaces of the mounting cylinder 2 and is compatible with the insertion hole 5. A pressing post 12 is inserted inside the adapter cylinder 11, and a positioning ring 14 is installed on the inner wall of the adapter cylinder 11, which is compatible with the pressing post 12. During disassembly, the two sets of pressing posts 12 are manually pressed. The pressing post 12 causes the positioning ring 14 to move downwards, which in turn causes the contact head 15 to move downwards and contact the top surface of the mounting ball 7. The pressure from the contact head 15 compresses and retracts the mounting ball 7 and the elastic contraction post 6, causing them to disengage from the adapter cylinder 11. Rotating the mounting post 3 then causes the mounting ball 7 to contact the inner wall of the mounting cylinder 2, allowing for quick disassembly. This makes overall disassembly convenient.
[0028] An elastic telescopic cylinder 13 is installed on the top surface of the positioning ring 14. An abutment spring is installed inside the elastic telescopic cylinder 13. An abutment head 15 is fixedly connected to the lower end surface of the pressing column 12. After the elastic telescopic cylinder 6 and the mounting ball 7 are moved away from the interior of the adapter cylinder 11 by the pressing of the abutment head 15, the pressing column 12 can automatically return to its original position after the pressing is released due to the elastic setting of the elastic telescopic cylinder 13. Therefore, the overall operation is relatively convenient.
[0029] Reinforcing side plates 16 are installed on the front and rear surfaces of both the mounting pad 8 and the stabilizing ring 9. The reinforcing side plates 16 have threaded grooves 17 inside, and threaded posts 18 are threaded into these grooves. Abutment pads 19 are installed on the back of the threaded posts 18. An adapter groove 20 is also provided on the back of the reinforcing side plates 16, and the adapter groove 20 and the abutment pad 19 are mutually compatible. When the mounting post 3 is fully installed inside the mounting cylinder 2, the installation of the mounting pad 8 and the stabilizing ring 9 will also cause the reinforcing side plates 16 to rotate. At this time, the reinforcing side plates 16 are fully fitted onto the front and rear surfaces of the mounting cylinder 2. Then, rotating the threaded post 18 inside the threaded groove 17 will cause the abutment pads 19 to fit against the front and rear surfaces of the mounting cylinder 2. Therefore, inside the adapter groove 20, the abutment pads 19 can stably abut against the front and rear surfaces of the mounting cylinder 2, further improving the stability of the mounting cylinder 2 and the mounting post 3 during installation.
[0030] Working principle: During installation, the mounting ball 7 is first squeezed to allow the mounting post 3 to enter the interior of the mounting cylinder 2. Then, the mounting post 3 is rotated so that the adapter thread 4 is threaded into the inner wall of the mounting cylinder 2. When the mounting pad 8 abuts against the right side of the mounting cylinder 2, the mounting ball 7 enters the interior of the adapter cylinder 11. At this time, the mounting post 3 and the drill bit body 10 can be installed quickly and at a fast speed. At the same time, the mounting pad 8 is elastic. When the mounting pad 8 is squeezed, it is stably clamped between the mounting cylinder 2 and the stabilizing ring 9, thus facilitating the quick installation of the drill bit body 10. The installation is achieved through the elastic contraction of the mounting post 6, the mounting ball 7 and the adapter cylinder 11.
[0031] During disassembly, the two sets of pressing columns 12 are manually pressed. This causes the positioning ring 14 to move downwards, and the pressing column 12 causes the contact head 15 to move downwards and contact the top surface of the mounting ball 7. The pressure from the contact head 15 compresses the mounting ball 7 and the elastic contraction column 6, causing them to detach from the adapter cylinder 11. The mounting column 3 is then rotated, causing the mounting ball 7 to contact the inner wall of the mounting cylinder 2. Rotating the mounting column 3 allows for quick disassembly, making overall disassembly convenient. After the contact head 15 presses the elastic contraction column 6 and the mounting ball 7 away from the adapter cylinder 11, the pressing column 12 automatically returns to its original position due to the elasticity of the elastic telescopic cylinder 13. This is the working principle of this utility model.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
