Description

Technical Field

[0001] The utility model relates to the technical field of automobile part processing, and more specifically, the utility model relates to a cutting device for automobile part production. Background Technique

[0002] Automobile parts are accessories that make up an automobile and are widely used in automobile maintenance and parts replacement. The shapes and sizes of automobile parts vary, including various materials, with wear parts and precision parts. Most automobile parts are metal products, and generally metal products formed by casting. Therefore, after the automobile parts are cast, a cutting device is required to optimize the required shape.

[0003] In the process flow of automobile part processing, the parts need to be cut according to the requirements of the drawings. However, the existing cutting devices cut the parts in the vertical direction without changing the orientation and inclination angle of the tool head. Sometimes, the cutting depths on the surface of the parts are different and the shapes are various, and quality problems such as uneven cutting surfaces, burrs, and cracks may occur during cutting. If the angle is too large or too small, excessive chips or excessive material loss may occur during cutting, thereby increasing costs and resource consumption. The existing devices are relatively single in use. Therefore, it is necessary to propose a welding device for part processing to improve and optimize it. Content of the Utility Model

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figures 1 to 7 shown, the present utility model provides a cutting device for automobile part production, including a U-shaped base 1, and an operating table 2 is slidably mounted on the top of the U-shaped base 1;

[0031] A fixing mechanism is slidably mounted on the top of the U-shaped base 1;

[0032] An adjusting mechanism is fixedly mounted inside the U-shaped base 1;

[0033] A rotating mechanism is slidably mounted inside the U-shaped base 1 and is arranged above the adjusting mechanism;

[0034] Among them, the rotating mechanism includes a rotating component and a linkage component. The rotating component includes a hydraulic cylinder 9 arranged inside the U-shaped base 1. An installation base 10 is hingedly mounted on the output shaft of the hydraulic cylinder 9. A driving motor 11 is fixedly mounted on the top of the installation base 10. A cutting knife 12 is fixedly mounted on the output shaft of the driving motor 11. A fixed block 14 is hingedly mounted at the bottom end of the installation base 10. A motor 2 13 is fixedly mounted on the left side of the fixed block 14. A lead screw 17 is fixedly mounted inside the fixed block 14. The left end of the U-shaped base 1 penetrates through the fixed block 14 and is fixedly connected to the output shaft of the motor 2 13.

[0035] When the staff is working, first place the parts to be cut on the operating table 2, then start the cylinder 3. The downward extension of the cylinder 3 drives the fixed block 14 to move downward, so as to fix the parts and prevent poor cutting quality caused by instability during cutting. Then, by starting the second motor 13, the second motor 13 drives the rotation of the lead screw 17, so that the internal thread block 15 and the nut connecting frame 18 slide on the lead screw 17. The sliding of the internal thread block 15 causes the right side of the mounting base 10 to be jacked up, thereby driving the angle of the cutting tool 12 in the mounting base 10 to change to the required angle. In addition, the same-direction rotation of the nut connecting frame 18 causes the nut connecting frame 18 to pull the operating table 2 to slide to the right, so that the cutting tool 12 is exactly aligned with the angle cutting edge of the operating table 2 for cutting. Then, by starting the hydraulic cylinder 9, the cutting tool 12 can rise to the position where it can cut. After that, start the driving motor 11 and the first motor 5. The driving motor 11 makes the cutting tool 12 operate. The first motor 5 drives the internal thread slider 8 to slide on the threaded rod 6 and under the limit of the limit rod 7, thereby driving the hydraulic cylinder 9 and the cutting tool 12 on the hydraulic cylinder 9 to slide to the right to cut other positions of the parts, so as to facilitate adjusting the cutting position and improve the cutting efficiency.

[0036] Through the power of the driving motor 11 and the second motor 13, the cutting tool 12 can adjust its angle through the movement of the internal thread block 15 to meet the cutting requirements. In this way, multi-angle adjustment is realized, more precise cutting is achieved, the replacement of the cutting tool 12 is reduced, the efficiency is improved, and the flexibility of the device is increased. Compared with the traditional device, through the rotation mechanism, the cooperation of the lead screw 17 and the internal thread block 15 enables the cutting tool 12 to adjust the angle well and be synchronized with the cutting edge groove on the operating table 2 at the same time, avoiding uneven cutting surfaces and meeting the cutting requirements of complex parts. Moreover, inaccurate angles may cause excessive chips or excessive material loss during the cutting process, greatly reducing the wear of the cutting tool, resulting in a shortened tool life and increasing the frequency and cost of replacing the tool.

[0037] Among them, small collection cabinets 32 are fixedly installed on the left and right sides of the operating table 2 respectively, a collection cabinet 33 is fixedly installed at the bottom end of the U-shaped base 1, and a fixing plate 22 is fixedly installed on the front surface of the operating table 2;

[0038] The cleaning mechanism is slidably installed on the front surface of the fixing plate 22;

[0039] The cleaning mechanism includes an adjustment component and a limit component. The adjustment component includes teeth 23 fixedly arranged on the front of a fixed plate 22. A connecting block 25 is slidably installed on the top of the fixed plate 22. The bottom of the connecting block 25 is connected to the fixed plate 22 by snapping. A movable mounting frame 24 is fixedly installed on the front of the connecting block 25. A mounting slide 29 is slidably installed on the front of the movable mounting frame 24. A motor 30 is fixedly installed on the inner wall of the mounting slide 29. A rotating shaft 31 is fixedly installed on the output shaft of the motor 30. A gear 27 is fixedly installed on the other end of the rotating shaft 31. The gear 27 is meshed with the teeth 23. A scraper 26 is fixedly installed on the back of the connecting block 25.

[0040] After the staff completes the cutting operation, part of the debris generated during cutting will fall into the collection cabinet 33 through the blade groove 34, and the remaining debris will be driven by starting the motor 30 to drive the gear 27 to rotate, and rotate along with the meshing teeth 23. Since the gear 27 is fixed to the mounting slide 29, the mounting slide 29 can slide on the movable mounting frame 24 according to the slide groove 28, limit the trajectory of the gear 27 and support the rotation of the gear, thereby driving the movable mounting frame 24 to move accordingly. The movable mounting frame 24 drives the connecting block 25 to slide on the top of the fixed plate 22, thereby driving the scraper 26 to scrape on the operating table 2. When the gear 27 moves to the lower teeth 23, the gear will bring the movable mounting frame 24 and the scraper 26 back for scraping, and small collection cabinets 32 are set on both sides of the scraping of the operating table 2 to collect the remaining debris for subsequent processing.

[0041] The power of the motor 30 drives the gear to rotate, so that the scraper 26 can swing back and forth on the operating table 2 to increase the cleaning force. Compared with the traditional device, the device uses the cleaning mechanism and the reciprocating motion of the scraper 26 to effectively remove the debris on the surface of the device, prevent the debris from long-term accumulation and adhesion on the surface of the device, so as to maintain the normal operation of the equipment, and through the reciprocating scraping, the cleaning effect is better, ensuring that the device can operate efficiently, reducing damage to the device, and increasing the service life of the device.

[0042] The limiting assembly includes slide grooves 28 respectively provided on the left and right sides of the movable mounting frame 24 , and the side surfaces of the mounting slide 29 extend into the two slide grooves 28 and are slidably connected with the slide grooves 28 .

[0043] The device of the utility model is provided with a slide groove 28, so that the installation slide 29 slides in the slide groove 28 and establishes a connection with the movable installation frame 24, thereby driving the movement of the movable installation frame 24, ensuring that the device works within a specific range of movement, and improving the safety of operation.

[0044] Among them, the fixing mechanism includes two cylinders 3 fixedly installed on the top of the operating table 2. The output shafts of the two cylinders 3 both extend into the operating table 2, and fixing blocks 14 are fixedly installed on the output shafts of the two cylinders 3 respectively.

[0045] In the device of the utility model, by starting the cylinder 3, the downward elongation of the cylinder 3 drives the fixing block 14 to move downward, thereby fixing the components and preventing poor cutting quality caused by instability during cutting.

[0046] Among them, the adjusting mechanism includes a first motor 5 fixedly installed on the right side of the U-shaped base 1. A threaded rod 6 is rotatably installed inside the U-shaped base 1. The right end of the threaded rod 6 extends outside the U-shaped base 1 and is fixedly connected to the output shaft of the first motor 5. An internally threaded slider 8 is sleeved on the outer wall of the threaded rod 6. A limiting rod 7 is fixedly installed inside the U-shaped base 1. The internally threaded slider 8 is slidably connected to the outer wall of the limiting rod 7. The top end of the internally threaded slider 8 is fixedly connected to the hydraulic cylinder 9.

[0047] In the device of the utility model, by starting the first motor 5, the first motor 5 drives the internally threaded slider 8 to slide on the threaded rod 6 and under the limitation of the limiting rod 7, thereby driving the hydraulic cylinder 9 and the cutting knife 12 on the hydraulic cylinder 9 to slide to the right to cut other positions of the component, so as to facilitate adjusting the cutting position and improving the cutting efficiency.

[0048] Among them, a cutting edge groove 34 is formed on the operating table 2, and the size of the cutting edge groove 34 is adapted to the cutting knife 12.

[0049] In the device of the utility model, by ensuring that a suitable cutting edge groove 34 corresponds to the cutting knife 12 when changing the angle of the cutting knife 12, the component is cut.

[0050] Among them, two installation chutes 20 are formed on the top inner wall of the U-shaped base 1, and the left and right sides of the operating table 2 respectively extend into the two installation chutes 20.

[0051] In the device of the utility model, by ensuring that the operating table 2 can slide smoothly and in a track on the U-shaped base 1 through the installation chutes 20.

[0052] Among them, the linkage assembly includes an internally threaded block 15 and a nut connection frame 18 slidably sleeved on the outer wall of the lead screw 17. The internally threaded block 15 is located on the left side of the nut connection frame 18. A hinge plate 16 is hingedly installed at the top of the internally threaded block 15. The other end of the hinge plate 16 is hingedly connected to the bottom end of the installation base 10. A sliding tooth groove 21 is formed on the back of the operating table 2, and a moving tooth block 19 is slidably installed in the sliding tooth groove 21. The top end of the nut connection frame 18 is slidably connected to the moving tooth block 19.

[0053] The working principle and usage process of the utility model:

[0054] When the staff is working, they first place the parts to be cut on the operating table 2, and then start the cylinder 3. The downward extension of the cylinder 3 moves the fixing block 14 downward, thereby fixing the parts to prevent instability during cutting and poor cutting quality. Then, the motor 13 is started, and the motor 13 drives the screw 17 to rotate, so that the internal thread block 15 and the nut connecting frame 18 slide on the screw 17. The sliding of the internal thread block 15 makes the right side of the mounting base 10 push up, thereby driving the angle of the cutting knife 12 in the mounting base 10 to change to the required angle. In addition, the nut connecting frame 1 The same-direction rotation of 8 causes the nut connecting frame 18 to pull the operating table 2 to slide to the right, so that the cutting knife 12 is just aligned with the angle of the operating table 2 for cutting, and then the hydraulic cylinder 9 is started to make the cutting knife 12 rise to a position where it can cut, and then the drive motor 11 and the motor 5 are started. The drive motor 11 makes the cutting knife 12 work, and the internal thread slider 8 is driven by the motor 5 to slide on the threaded rod 6 and under the limit of the limit rod 7, thereby driving the hydraulic cylinder 9 and the cutting knife 12 on the hydraulic cylinder 9 to slide to the right to cut other positions of the parts, thereby facilitating the adjustment of the cutting position and improving the cutting efficiency.

[0055] By driving the power of the motor 11 and the motor 2 13, the cutting knife 12 can adjust its angle by moving the internal thread block 15 to meet the cutting requirements. In this way, multi-angle adjustment can be achieved, more precise cutting can be achieved, and the replacement of the cutting knife 12 can be reduced, efficiency can be improved, and the flexibility of the device can be increased. Compared with the traditional device, the device uses a rotating mechanism, and the cooperation of the lead screw 17 and the internal thread block 15 allows the cutting knife 12 to adjust the angle and synchronize with the blade groove on the operating table 2 at the same time, avoiding uneven cutting surface and meeting the cutting requirements of complex parts. In addition, if the angle is inaccurate, excessive chips or excessive material loss may be generated during the cutting process, which greatly reduces the wear of the cutting tool, resulting in a shortened tool life and an increased frequency and cost of tool replacement.

[0056] After the staff completes the cutting operation, part of the debris generated during cutting will fall into the collection cabinet 33 through the blade groove 34, and the remaining debris will be driven by starting the motor 30 to drive the gear 27 to rotate, and rotate along with the meshing teeth 23. Since the gear 27 is fixed to the mounting slide 29, the mounting slide 29 can slide on the movable mounting frame 24 according to the slide groove 28, limit the trajectory of the gear 27 and support the rotation of the gear, thereby driving the movable mounting frame 24 to move accordingly. The movable mounting frame 24 drives the connecting block 25 to slide on the top of the fixed plate 22, thereby driving the scraper 26 to scrape on the operating table 2. When the gear 27 moves to the lower teeth 23, the gear will bring the movable mounting frame 24 and the scraper 26 back for scraping, and small collection cabinets 32 are set on both sides of the scraping of the operating table 2 to collect the remaining debris for subsequent processing.

[0057] The power of the motor 30 drives the gear to rotate, so that the scraper 26 can swing back and forth on the operating table 2 to increase the cleaning force. Compared with the traditional device, the device uses the cleaning mechanism and the reciprocating motion of the scraper 26 to effectively remove the debris on the surface of the device, prevent the debris from long-term accumulation and adhesion on the surface of the device, so as to maintain the normal operation of the equipment, and through the reciprocating scraping, the cleaning effect is better, ensuring that the device can operate efficiently, reducing damage to the device, and increasing the service life of the device.
