Abstract
Description
Technical Field
[0001] This utility model relates to the field of bolt processing technology, specifically a self-cleaning bolt grinding tool. Background Technology
[0002] A bolt is a type of fastener consisting of a head and a shank (a cylinder with external threads). It needs to be used with a nut to fasten two parts with through holes. In the bolt manufacturing process, grinding is a key step in improving the surface quality and precision of the bolt.
[0003] A related technology (publication number: CN219747326U) discloses a grinding device for the sharp end of a track bolt. The disclosed technical solution is as follows: the track bolt is fixed on the rotating block by tightening the bolt. According to the height of the end of the track bolt, the grinding wheel is controlled by a lifting motor to move vertically so that the height of the grinding wheel is the same as the end of the track bolt, which facilitates the grinding wheel to grind the end of the track bolt. When the distance between the track bolt and the grinding wheel is far, the working platform is moved by a screw motor, so that the track bolt on the working platform moves laterally to get closer to the grinding wheel, which facilitates the grinding wheel to grind.
[0004] The above-disclosed technical solutions reveal the following problems: a large amount of metal chips are generated during the grinding process. If these chips are not dealt with in time on the processing table, they will accumulate and affect subsequent processing. In response, we propose a self-cleaning bolt grinding tool.
[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content
[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the problem of cleaning after bolt grinding in the prior art, this utility model provides a self-cleaning bolt grinding tool. It employs a self-cleaning structure combined with a sieving structure to ensure a clean processing environment. The specific technical solution is as follows:
[0007] A self-cleaning bolt grinding tool includes a processing table, a filter chamber fixedly connected to the bottom of the processing table, a discharge hopper fixedly connected to the bottom of the filter chamber, a material drop groove extending into the inner cavity of the filter chamber from the top of the processing table, a cleaning scraper fitted to the bottom of the inner wall of the processing table, and a scraping assembly for driving the cleaning scraper to slide circumferentially on the processing table. A grinding machine is arranged above the processing table, and an electric push rod is fixedly connected to the outer wall of the processing table, with a clamp fixedly connected to the movable end of the electric push rod facing the grinding machine.
[0008] In the above technical solution, a sieve plate is embedded in the inner cavity of the filter chamber, a replacement slot is opened on the outer wall of the filter chamber, and a slot door covering the outside of the replacement slot is rotatably provided on the outer wall of the filter chamber. A fixing member for locking on the outer wall of the filter chamber is provided on the slot door, and a vibrating sieve assembly for driving the sieve plate to vibrate is provided on the discharge hopper.
[0009] The vibrating screen assembly includes a slide rod disposed at the bottom of the screen plate, a pusher seat fixedly connected to the bottom end of the slide rod, the slide rod passing through the bottom of the discharge hopper and extending outward, an elastic element sleeved on the outer wall of the slide rod being disposed between the pusher seat and the discharge hopper, and support legs being uniformly fixedly connected to the bottom of the discharge hopper, with cams rotatably disposed on the side walls of the support legs and conforming to the bottom of the pusher seat.
[0010] The clamp includes a base fixed to the movable end of the electric push rod, a clamping plate fixed to the side wall of the base, a threaded post fixed to the side wall of the clamping plate, a locking seat threaded to the outer wall of the threaded post, and a clamping movable plate located between the locking seat and the clamping plate sleeved on the outside of the threaded post.
[0011] A clamping cavity is formed between the fixed clamping plate and the movable clamping plate.
[0012] The scraping assembly includes a rotating shaft rotatably disposed at the center of the inner wall of the processing table, and the cleaning scraper is sleeved on the outer wall of the rotating shaft. A base platform located above the rotating shaft is fixedly installed on the outer wall of the processing table, and the grinder is fixedly installed at the bottom of the base platform.
[0013] The lower end of the rotating shaft is rotatably mounted on the machining table via a tapered seat.
[0014] The bottom of the sieve plate is fixedly connected to a docking seat, and the slide rod is threadedly connected to the bottom of the docking seat.
[0015] A discharge pipe is fixedly connected to the bottom of the discharge hopper.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. The scraping component allows the cleaning scraper to slide continuously circumferentially against the bottom of the inner wall of the processing table. As it scrapes the debris on the processing table in a continuous circumferential motion, the cleaning scraper pushes the debris to the discharge chute. The debris enters the filter chamber through the discharge chute and is then discharged to the outside through the discharge hopper. This ensures that the debris on the processing table is cleaned in a timely manner, preventing the debris from accumulating on the processing table and thus avoiding any impact on subsequent processing.
[0018] 2. Fix the bolt with a clamp, then connect the grinder and the electric push rod to the power supply. The movable end of the electric push rod drives the bolt to move towards the grinder through the clamp, thereby grinding the bolt. The debris from the process falls onto the processing table, making the bolt grinding process more convenient.
[0019] Third, after the debris is scraped off into the filter chamber by the circumferentially rotating cleaning scraper, the screen plate slides up and down on the inner wall of the filter chamber by the vibrating screen assembly. Large debris remains on the screen plate, while small debris is discharged to the outside through the discharge hopper. The vibrating screen plate prevents large debris from clogging the discharge pipe. Attached Figure Description

Detailed Implementation
[0026] 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.
[0027] The following are specific implementation cases and appendices. Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.
[0028] A self-cleaning bolt grinding tool includes a processing table 1, a filter chamber 2 fixedly connected to the bottom of the processing table 1, a discharge hopper 3 fixedly connected to the bottom of the filter chamber 2, and a material discharge chute 4 extending into the inner cavity of the filter chamber 2 from the top of the processing table 1. The processing table 1 is located in a recessed chamber structure, and the inner cavity of the processing table 1 is connected to the filter chamber 2 through the material discharge chute 4. The discharge hopper 3 is fixedly installed at the bottom of the filter chamber 2, and the inner cavities of the filter chamber 2 and the discharge hopper 3 are connected. A cleaning scraper 5 is attached to the bottom of the inner wall of the processing table 1, and a scraping assembly is provided on the processing table 1 to drive the cleaning scraper 5 to slide circumferentially. The scraping assembly causes the cleaning scraper 5 to slide continuously circumferentially against the bottom of the inner wall of the processing table 1. As the scraper continuously scrapes the debris on the processing table 1 circumferentially, the cleaning scraper 5 pushes the debris to the material discharge chute 4, through which the debris enters the interior of the filter chamber 2, and is then discharged to the outside through the discharge hopper 3. This ensures that the debris on the processing table 1 is cleaned up in a timely manner, preventing debris from accumulating on the processing table 1 and thus avoiding any impact on subsequent processing.
[0029] A grinding machine 27 is installed above the processing table 1. An electric push rod 6 is fixedly connected to the outer wall of the processing table 1, and a clamp facing the grinding machine 27 is fixedly connected to the movable end of the electric push rod 6. The electric push rod 6 is fixedly installed on the circumferential outer wall of the processing table 1 through a base frame, and the movable end of the electric push rod 6 points to the center of the processing table 1. The electric push rod 6 is used after being connected to an external power source through a wire.
[0030] The bolt is fixed by a clamp, and then the grinder 27 and the electric push rod 6 are connected to the power supply respectively. The movable end of the electric push rod 6 drives the bolt to move towards the grinder 27 through the clamp, thereby grinding the bolt. The debris from the process falls onto the processing table 1, making the bolt grinding process more convenient.
[0031] The filter chamber 2 has a screen plate 18 embedded in its inner cavity. A replacement slot 19 is formed on the outer wall of the filter chamber 2, and a door 8 is rotatably mounted on the outer wall of the filter chamber 2, covering the outside of the replacement slot 19. The door 8 is equipped with a fixing member 15 for locking onto the outer wall of the filter chamber 2. A vibrating screen assembly that drives the screen plate 18 to vibrate is mounted on the discharge hopper 3. The specifications of the screen plate 18 correspond to those of the filter chamber 2, allowing it to fit snugly against the inner wall of the filter chamber 2. A semi-circular replacement slot 19 is formed on the circumferential outer wall of the filter chamber 2, through which the screen plate 18 can be removed for replacement.
[0032] A rotating shaft is installed on the outer wall of the filter chamber 2 via a bracket. One end of the slot door 8 is fixedly sleeved on the outside of the rotating shaft through an opening in the mounting hole. The other end of the slot door 8 is fixedly installed with a locking seat 17. A locking bolt 15 is threaded onto the locking seat 17. After the slot door 8 is rotated to fit against the outside of the replacement slot 19, the locking bolt 15 on the locking seat 17 is turned to engage the locking bolt 15 in the bayonet on the outer wall of the filter chamber 2, thereby closing and locking the slot door 8.
[0033] After the debris is scraped into the filter chamber 2 by the circumferentially rotating cleaning scraper 5, the screen plate 18 slides up and down on the inner wall of the filter chamber 2 by the vibrating screen assembly. Large debris remains on the screen plate 18, while small debris is discharged to the outside through the discharge hopper 3. The vibrating screen plate 18 prevents large debris from clogging the discharge pipe 26, and the screened waste is taken out through the replacement trough 19.
[0034] It is worth noting that the vibrating screen assembly includes a slide rod 9 located at the bottom of the screen plate 18. A pusher seat 14 is fixedly connected to the bottom end of the slide rod 9. The slide rod 9 passes through the bottom of the discharge hopper 3 and extends outward. An elastic element 12 is provided between the pusher seat 14 and the discharge hopper 3, sleeved on the outer wall of the slide rod 9. The elastic element 12 can be a compression spring. The two ends of the elastic element 12 are respectively fixed to the bottom of the discharge hopper 3 and the top of the pusher seat 14. The elastic element 12 slides and extends against the outer wall of the slide rod 9. Support legs 28 are evenly fixed to the bottom of the discharge hopper 3. Cams 13 are rotatably provided on the side walls of the support legs 28, fitting against the bottom of the pusher seat 14. The motor is fixed to the outer wall of the corresponding support leg 28 through the frame. The cam 13 is fixedly sleeved on the outer wall of the motor output shaft through the mounting hole. The motor is connected to an external power source through wires.
[0035] The rotating cam 13 causes the pusher seat 14 to move, which in turn causes the pusher seat 14 to move the screen plate 18 via the slide rod 9. At this time, the elastic element 12 is compressed and generates elastic force. When the cam 13 rotates to the point where it is disengaged from the bottom of the pusher seat 14, the elastic force of the elastic element 12 causes the pusher seat 14 to move the screen plate 18 again via the slide rod 9, so that the screen plate 18 vibrates up and down once for every revolution of the cam 13.
[0036] In addition, the clamp includes a base 21 fixed to the movable end of the electric push rod 6. A clamping stationary plate 22 is fixed to the side wall of the base 21, and a threaded post 24 is fixed to the side wall of the clamping stationary plate 22. A locking seat 25 is threaded to the outer wall of the threaded post 24, and a clamping movable plate 23 is sleeved on the outside of the threaded post 24, located between the locking seat 25 and the clamping stationary plate 22. The movable end of the electric push rod 6 is vertically fixed to the surface of the base 21. A bent clamping stationary plate 22 is fixedly installed on the other side surface of the base 21. The threaded post 24 is vertically fixed to the surface of the clamping stationary plate 22. A through hole penetrating the inner cavity is opened on the surface of the clamping movable plate 23, and the clamping movable plate 23 is movably sleeved on the outside of the threaded post 24 through the opened through hole.
[0037] Place the bolt to be processed between the clamping stationary plate 22 and the clamping moving plate 23, and then tighten the locking seat 25 on the outer wall of the threaded post 24 to fix the bolt by the tightness of the locking seat 25. Fix it according to the bolt specifications and the grinding position.
[0038] In addition, a clamping cavity is formed between the clamping fixed plate 22 and the clamping moving plate 23. The transverse cross-sections of both the clamping fixed plate 22 and the clamping moving plate 23 are obtuse angles. The clamping cavity formed between the clamping fixed plate 22 and the clamping moving plate 23 ensures the stability of the bolt grinding process. At the same time, pads are installed on the inner walls of both the clamping fixed plate 22 and the clamping moving plate 23 to avoid damage to the bolt surface.
[0039] Furthermore, the scraping assembly includes a rotating shaft 10 rotatably disposed at the center of the inner wall of the processing table 1, and a cleaning scraper 5 sleeved on the outer wall of the rotating shaft 10. A base 7 located above the rotating shaft 10 is fixedly installed on the outer wall of the processing table 1, and a grinder 27 is fixedly installed at the bottom of the base 7. A motor is fixed on the top of the base 7 by a cover, and the output shaft of the motor is fixedly connected to one end of the rotating shaft 10. The base 7 is fixed to the circumferential outer wall of the processing table 1 by a semi-circular fixing bracket 11.
[0040] The motor is connected to an external power source via a wire. The output shaft of the motor drives the rotating shaft 10 to rotate, causing the cleaning scraper 5 to slide circumferentially against the bottom of the inner wall of the processing table 1, thereby processing the debris.
[0041] The lower end of the rotating shaft 10 is rotatably mounted on the machining table 1 via a tapered seat 16. The tapered seat 16 is fixedly installed at the center of the bottom of the inner wall of the machining table 1. Bearings are embedded in the opposite surfaces of the tapered seat 16 and the base 7. The two ends of the rotating shaft 10 are respectively embedded in the two bearings. The stability of the rotating shaft 10 is ensured by the base 7 and the tapered seat 16.
[0042] A docking seat 20 is fixedly connected to the bottom of the screen plate 18, and the slide rod 9 is threaded to the bottom of the docking seat 20. An external thread is opened on the outer wall of the top of the slide rod 9, and an internal thread groove is opened on the bottom of the docking seat 20, which makes the operation of changing the screen plate 18 convenient.
[0043] A discharge pipe 26 is fixedly connected to the bottom of the discharge hopper 3. The discharge pipe 26 is fixedly installed at the center of the bottom of the discharge hopper 3, and a valve is installed on the discharge pipe 26 to control the opening and closing of the discharge pipe 26.
