Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a cutting device for producing brake discs with a fixed structure. Background Technology

[0002] The brake disc is a key component of a car's braking system. It is usually a metal disc mounted on the wheel hub. Its main function is to achieve vehicle braking through friction with the brake pads. When the driver presses the brake pedal, the brake caliper presses the brake pads firmly against the rotating brake disc, generating strong friction that rapidly reduces the speed of the brake disc, thereby slowing the wheels down until they come to a stop. This ensures that the vehicle can brake in a timely and effective manner when needed, ensuring driving safety.

[0003] Chinese Patent Publication No. CN217529406U discloses a cutting device for automobile brake disc production, including a base, a cutting mechanism, and a controller. Side plates are fixedly connected to both sides of the upper surface of the base. The cutting mechanism is installed at the top of the side plates. A moving mechanism is installed near the bottom of the adjacent surfaces of the two side plates, and a clamping mechanism is installed on the moving mechanism. This utility model places the workpiece on two support rods. The controller opens a second electric telescopic rod, which moves downwards. The two sides of the clamping groove are tangent to the two sides of the workpiece, and the workpiece is also tangent to the two support rods, thus forming an inscribed circle of a quadrilateral. Therefore, when clamping cylindrical workpieces, slippage is avoided, improving cutting efficiency. The clamping mechanism is fixedly mounted on the moving mechanism, facilitating its reciprocating movement and providing convenience during use.

[0004] Although the existing device can clamp cylindrical workpieces, it cannot adjust the distance between the support rods. When in use, the support rods cannot accommodate some smaller brake discs and cannot provide effective support, which makes it inconvenient for workers to perform cutting operations, resulting in low applicability of the existing device.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Reference Figure 1-5 A cutting device for brake disc production with a fixed structure includes a device housing 1. A processing cavity 2 is formed inside the device housing 1. A fixing assembly 3 is disposed inside the processing cavity 2. The fixing assembly 3 includes an electric push rod 301, a clamping plate 302, a limiting groove 303, a limiting slider 304, a rubber pad 305, a transmission column 306, a transmission disc 307, a transmission groove 308, a transmission gear 309, a second electric push rod 310, and a rack 311. The first electric push rod 301 is fixedly installed on the left inner wall of the processing cavity 2. The clamping plate 302 is fixedly connected to the telescopic end of the first electric push rod 301. The limiting groove 303 is formed at the end of the clamping plate 302 away from the first electric push rod 301. The first limiting slider 304 is slidably connected to... Inside the limiting slide groove 303, a rubber pad 305 is fixedly connected to the side of the limiting slider 304. A transmission column 306 is fixedly connected to the left end of the limiting slider 304 near the electric push rod 301 and located inside the clamping plate 302. A transmission disc 307 is rotatably connected to the inside of the clamping plate 302. A transmission groove 308 is opened inside the transmission disc 307. The transmission column 306 is located inside the transmission groove 308. A transmission gear 309 is fixedly connected to the end of the transmission disc 307 connected to the clamping plate 302. An electric push rod 310 is fixedly installed on the outer surface of the clamping plate 302. The telescopic end of the electric push rod 310 extends into the inside of the clamping plate 302, and a rack 311 is fixedly installed on the telescopic end of the electric push rod 310.

[0025] The limiting slide groove 303 is arranged in a rectangular array. The transmission groove 308 is adapted to the transmission column 306. Through the installation of the rubber pad 305, the limiting slide 304 can not only increase the friction with the workpiece during the clamping process, but also protect the surface of the workpiece. The installation of the electric push rod 301 can drive the clamping plate 302 and other components to move left and right, thereby completing the left and right adjustment of the workpiece position. The setting of the fixing component 3, by activating the electric push rod 310, causes the extension end of the electric push rod 310 to drive... As rack 311 descends, it synchronously drives transmission gear 309 to rotate clockwise, which in turn drives transmission disc 307 to rotate clockwise. Simultaneously, transmission disc 307, through transmission groove 308, actuates transmission column 306, causing limit slider 304 to move within limit groove 303, thus clamping and fixing the workpiece. Furthermore, electric push rod 301 can be activated, extending its telescopic end to adjust the workpiece's position left or right. This invention, through the transmission of electric push rod 310, causes transmission disc 307 to rotate, driving limit slider 304 to clamp the workpiece. This not only effectively improves the safety and stability of workpiece placement but also significantly enhances applicability to workpieces of different sizes, facilitating cutting operations for workers.

[0026] Furthermore, the interior of the processing cavity 2 is provided with a lifting assembly 4, which includes a second limiting slide groove 401, a threaded rod 402, a stepper motor 403, a second limiting slider 404, a placement table 405, a rotary motor 406, and a cutting blade 407. The second limiting slide groove 401 is opened on the inner right side of the processing cavity 2, the threaded rod 402 is rotatably connected to the interior of the second limiting slide groove 401, and the stepper motor 403 is fixedly installed on the top of the device housing 1.

[0027] The output end of the stepper motor 403 is connected to the threaded rod 402 for transmission. The second limiting slider 404 is slidably connected inside the second limiting groove 401 and threadedly connected to the threaded rod 402. The placement platform 405 is fixedly connected to the left side of the second limiting slider 404. The rotary motor 406 is fixedly installed on the top of the placement platform 405. The cutting blade 407 is fixedly installed on the transmission end of the rotary motor 406.

[0028] The second limiting slider 404 is adapted to the second limiting groove 401. The lifting assembly 4, by activating the stepper motor 403, drives the threaded rod 402 at its output end to rotate. During rotation, the second limiting slider 404 moves up and down due to its adaptation to the second limiting groove 401 and its threaded connection to the threaded rod 402. This movement allows for adjustment of the height of the cutting blade 407. When the cutting blade 407 is in the appropriate position, the rotary motor 406 is activated, causing the cutting blade 407 to rotate, thus performing the cutting operation on the workpiece. This invention, by using the stepper motor 403 to drive the rotation of the threaded rod 402, causes the second limiting slider 404 to move up and down, facilitating the adjustment of the cutting blade 407's height and effectively improving practicality and convenience.

[0029] Furthermore, a slag discharge groove 5 is provided on the lower surface of the processing cavity 2, a control panel 6 is fixedly installed on the front end of the device housing 1, and a protective door 7 is rotatably connected to the front end of the device housing 1 and above the control panel 6.

[0030] The protective door 7 has an observation slot 8 inside, and tempered glass is installed inside the observation slot 8. Support columns 9 are fixedly installed in a rectangular array at the bottom of the device housing 1, and support platforms 10 are fixedly connected to the bottom of the support columns 9.

[0031] The slag discharge trough 5 is used to discharge the debris generated during the cutting operation. The observation trough 8 allows the staff to observe the cutting status of the workpiece inside the processing chamber 2. The installation of the protective door 7 can prevent the debris generated during the cutting process from splashing, thus improving the safety of the staff.

[0032] Furthermore, the transmission groove 308 is arc-shaped, the limiting slider 304 is adapted to the limiting groove 303, and the rack 311 is meshed with the transmission gear 309.

[0033] In summary:

[0034] In use, the workpiece is first placed between the limiting sliders 304, and the electric push rod 310 is activated. The telescopic end of the electric push rod 310 drives the rack 311 to descend. When the rack 311 descends, it synchronously drives the transmission gear 309 to rotate clockwise, thereby driving the transmission disc 307 to rotate clockwise. While the transmission disc 307 is rotating, it moves the transmission column 306 through the transmission groove 308, thereby driving the limiting sliders 304 to move inside the limiting groove 303. Then, the workpiece to be processed can be clamped and fixed. In addition, the electric push rod 301 can be activated, so that the telescopic end of the electric push rod 301 extends, thereby adjusting the position of the workpiece left and right.

[0035] Next, the stepper motor 403 is started, causing the stepper motor 403 to drive the threaded rod 402 at the output end to rotate. During the rotation of the threaded rod 402, due to the matching of the limit slider 404 with the limit groove 401 and the threaded connection with the threaded rod 402, the limit slider 404 can be driven to move up and down. During the movement, the height of the cutting blade 407 can be adjusted. When the cutting blade 407 is in the appropriate position, the rotary motor 406 can be started, causing the rotary motor 406 to drive the cutting blade 407 to rotate, thereby performing the cutting operation on the workpiece to be processed.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
