Description

Technical Field

[0001] This utility model relates to the field of automotive sunroof guide rail technology, specifically a high-precision metal cutting device. Background Technology

[0002] When processing sunroof guide rails, a sawing machine is needed to remove excess material and cut the sunroof guide rails to the appropriate length. After all the guide rails are processed, the guide rails of different lengths are assembled together to form a complete car sunroof guide rail, which controls the guiding movement of the car sunroof and facilitates the opening and closing of the sunroof.

[0003] Chinese patent CN221639671U discloses a cutting device for automotive sunroof guide rails, relating to the field of automotive sunroof guide rail processing technology. The device includes a shelf; a first sliding frame is slidably connected to the top of the shelf, and a second sliding frame is slidably connected to the top front end of the first sliding frame. The front end of the second sliding frame has an L-shaped design, and a reversing frame is fixedly connected to the middle position of the upper part of the second sliding frame. This patent uses a motor to drive a cutting blade to rotate, and a lateral and longitudinal movement mechanism to bring the cutting blade close to the automotive sunroof guide rail for cutting.

[0004] The existing technology uses a motor to drive a rotating cutting blade, which is then moved laterally and longitudinally to bring the blade close to the sunroof rail for cutting. However, this cutting method often results in burrs at the cut edge of the sunroof rail. These burrs not only affect the appearance quality of the sunroof rail, but more importantly, they compromise the flatness and precision of the rail surface, negatively impacting the assembly precision with other components and reducing the overall performance and sealing of the sunroof. To eliminate these burrs and ensure the quality of the sunroof rail, the current process requires sending the cut sunroof rail to a grinding machine for polishing. However, this subsequent polishing operation has several inconveniences. On the one hand, the polishing process increases the complexity and cycle time of the entire production process, significantly reducing production efficiency. The transfer from the cutting equipment to the grinding machine is not only time-consuming but also increases the risk of damage to the workpiece during transport. On the other hand, the polishing operation requires additional manpower and equipment, increasing production costs. Moreover, the quality stability of manual polishing is difficult to guarantee; different operators may produce different results, further affecting the consistency of the sunroof rail's quality. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision metal cutting device. By setting a cutting disc and a grinding disc, and switching the positions of the cutting disc and the grinding disc by a switching device, the burrs on the cut surface of the car sunroof guide rail can be removed after cutting.

[0006] To address the problems of existing technologies, this utility model provides a high-precision metal cutting device for cutting automotive sunroof rails. The device includes a main body, a clamping device at the center of the main body, and a cutting device on the back of the clamping device for cutting the automotive sunroof rails. The clamping device includes at least two clamping components that can synchronously move closer or further apart. The cutting device includes a cutting component that can move up and down, comprising a cutting blade and a grinding blade, and further includes a switching device for switching the positions of the cutting blade and the grinding blade.

[0007] Preferably, the switching device includes a connecting plate, and the cutting disc and the grinding disc are respectively disposed at both ends of the connecting plate. The cutting device includes a lifting plate that can move up and down. The switching device also includes a first rotary drive component fixed on the lifting plate and used to drive the connecting plate to rotate, and the output end of the first rotary drive component is connected to the center position of the connecting plate.

[0008] Preferably, a driven wheel is connected to the center of the cutting disc and the grinding disc, a second rotary drive is fixed to the front end of the lifting plate, and a drive wheel is connected to the output end of the second rotary drive. The drive wheel and the driven wheel are connected by a belt.

[0009] Preferably, the cutting device includes a first moving mechanism for moving the cutting component in the lateral direction along the sunroof guide rail of the vehicle, and a second moving mechanism for moving the cutting component up and down is provided on the first moving mechanism, and the lifting plate is provided on the second moving mechanism.

[0010] Preferably, the clamping assembly includes a support plate that can slide on the main body and is used to support the sunroof guide rail. The support plate is provided with two clamping members that move synchronously and can fix the sunroof guide rail. A sliding rod is connected to the clamping member. The support plate is also provided with a connecting block that can cooperate with the sliding rod. A support block is also provided on the side of the support plate. The clamping device also includes a synchronization component for driving the two clamping assemblies to move synchronously.

[0011] Preferably, the clamping assembly further includes a connecting rod rotatably mounted on the support block, and both ends of the connecting rod are provided with sliding grooves. The end of the sliding rod away from the clamping member is provided with a shaft that can engage with the sliding groove at the top of the connecting rod.

[0012] Preferably, the clamping assembly further includes a second telescopic drive member fixed to the bottom of the support plate, and the output end of the second telescopic drive member is provided with a shaft that can cooperate with the sliding groove at the bottom end of the connecting rod.

[0013] Preferably, the synchronization component includes a gear disposed at the bottom of the main body, and the synchronization component also includes two racks respectively connected to the support plate, the racks meshing with the gear, and the synchronization component also includes a first telescopic drive member fixed on the main body and used to drive one of the racks.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. This application includes a cutting assembly that integrates both cutting and grinding functions, enabling efficient cutting and grinding of automotive sunroof rails. In practical use, the cutting disc, as the primary cutting tool, quickly cuts the sunroof rail, ensuring a smooth cut surface. After cutting, if grinding is required to remove burrs and improve surface quality, the first rotary drive plays a crucial role. Driven by the first rotary drive, the connecting plate rotates around its axis, thus switching the positions of the cutting disc and the grinding disc. This allows for contact with the cut surface, uniformly removing burrs and micro-protrusions, resulting in a smoother and flatter surface, effectively improving production efficiency and product quality. This integrated cutting and grinding design avoids the cumbersome process of transferring the workpiece to a grinding machine for secondary processing after cutting, significantly shortening the production cycle and reducing production costs.

[0016] 2. This application also includes a synchronization component. The main function of the synchronization component is to quickly separate the sunroof guide rails after cutting, leaving sufficient space for subsequent deburring operations. Specifically, after the cutting component completes the cutting of the sunroof guide rail, the first telescopic drive component starts working, driving the rack to move linearly through its own telescopic movement. Since the rack and gear mesh with each other, according to the principle of gear transmission, when one rack moves, it drives the gear to rotate, and the rotation of the gear drives the other rack to move in the opposite direction. The two racks move in opposite directions simultaneously, thus separating the cut sunroof guide rails to both sides. This synchronous separation design is not only simple to operate and highly efficient, but also ensures that the cut sunroof guide rails are separated, providing sufficient space for subsequent finishing operations such as grinding, and avoiding processing difficulties and quality problems caused by insufficient space.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] Reference Figures 1-6 As shown, this utility model provides a high-precision metal cutting device for cutting automotive sunroof rails. It includes a main body 1, with a clamping device 2 at its center. A cutting device 3 for cutting the automotive sunroof rails is located on the back of the clamping device 2. The clamping device 2 includes at least two clamping components 22 that can synchronously move closer or further apart. The cutting device 3 includes a cutting component 34 that can move up and down. The cutting component 34 includes a cutting blade 343 and a grinding blade 344, and also includes a switching device for switching the positions of the cutting blade 343 and the grinding blade 344. The cutting component 34 is the core part of the cutting device 3, containing the cutting blade 343 and the grinding blade 344. The cutting blade 343 is used for initial cutting of the automotive sunroof rails, breaking them apart; the grinding blade 344 is used to grind the cut surface after cutting, removing burrs and improving the surface quality of the cut. In addition, the cutting assembly 34 is also equipped with a switching device that can switch the positions of the cutting disc 343 and the grinding disc 344 to achieve the switching between cutting and grinding functions.

[0026] The sunroof guide rail to be cut is placed in the clamping device 2. The clamping components 22 of the clamping device 2 move closer to each other synchronously, firmly clamping the guide rail and ensuring that it will not shift during the cutting process. Next, the cutting device 3 starts working. The cutting component 34 moves downward, bringing the cutting blade 343 into contact with the sunroof guide rail, and then rotates at high speed to cut the guide rail. After the cutting is completed, if it is necessary to polish the cut, the switching device is activated, switching the positions of the cutting blade 343 and the polishing blade 344 in the cutting component 34, rotating the polishing blade 344 to the working position. Then, the cutting component 34 moves again, bringing the polishing blade 344 into contact with the cut, polishing the burrs and uneven parts at the cut, and improving the quality of the cut.

[0027] The switching device includes a connecting plate 341, and the cutting disc 343 and the grinding disc 344 are respectively disposed at both ends of the connecting plate 341. The cutting device 3 includes a lifting plate 33 that can move up and down. The switching device also includes a first rotary drive 342 fixed on the lifting plate 33 and used to drive the connecting plate 341 to rotate, and the output end of the first rotary drive 342 is connected to the center position of the connecting plate 341.

[0028] The first rotary drive 342 is activated, and its output drives the connecting plate 341 to rotate around the center position. Since the cutting disc 343 and the grinding disc 344 are respectively installed at both ends of the connecting plate 341, the rotation of the connecting plate 341 causes the positions of the cutting disc 343 and the grinding disc 344 to change, rotating the grinding disc 344 to the working position.

[0029] A driven wheel is connected to the center of the cutting disc 343 and the grinding disc 344. A second rotary drive 345 is fixed to the front end of the lifting plate 33, and a drive wheel is connected to the output end of the second rotary drive 345. The drive wheel and the driven wheel are connected by a belt.

[0030] At this time, the second rotary drive component 345 starts working, and its output end drives the drive wheel to rotate. The drive wheel drives the driven wheel connected to the center of the cutting disc 343 to rotate via a belt, thereby causing the cutting disc 343 to rotate at high speed and perform cutting operations on the guide rail. Similarly, through the transmission of the drive wheel and the belt, the driven wheel connected to the center of the grinding disc 344 is driven to rotate, causing the grinding disc 344 to rotate at high speed and grind the burrs and uneven parts at the cut, thereby improving the cut quality.

[0031] The cutting device 3 includes a first moving mechanism 31 that enables the cutting component 34 to move in the lateral direction of the car sunroof guide rail, and a second moving mechanism 32 that enables the cutting component 34 to move up and down is provided on the first moving mechanism 31, and the lifting plate 33 is provided on the second moving mechanism 32.

[0032] The first moving mechanism 31 functions to move the cutting assembly 34 laterally along the sunroof guide rail. The first moving mechanism 31 is typically equipped with a drive unit and transmission components, such as a motor, lead screw and nut assembly, or guide rail slider. By precisely controlling the operation of the drive unit, the cutting assembly 34 can be accurately positioned laterally for processing the guide rail at different locations. The second moving mechanism 32 functions to move the cutting assembly 34 vertically. The second moving mechanism 32 also has drive and transmission components, enabling precise control of the vertical position of the cutting assembly 34, ensuring accurate contact between the cutting disc 343 and the grinding disc 344 with the guide rail or cut, guaranteeing effective cutting and grinding.

[0033] The clamping assembly 22 includes a support plate 221 that can slide on the main body 1 and supports the sunroof guide rail. Two clamping members 222 that move synchronously and can fix the sunroof guide rail are provided on the support plate 221. A sliding rod 223 is connected to each clamping member 222. A connecting block 2211 that cooperates with the sliding rod 223 is also provided on the support plate 221. A support block 2212 is also provided on the side of the support plate 221. The clamping device 2 further includes a synchronizing assembly 21 for driving the two clamping assemblies 22 to move synchronously. The clamping assembly 22 also includes a connecting rod 224 rotatably mounted on the support block 2212. Both ends of the connecting rod 224 have sliding grooves. The end of the sliding rod 223 away from the clamping member 222 has a shaft that cooperates with the sliding groove at the top of the connecting rod 224. The clamping assembly 22 also includes a second telescopic drive member 225 fixed to the bottom of the support plate 221, and the output end of the second telescopic drive member 225 is provided with a shaft that can cooperate with the slide groove at the bottom of the connecting rod 224.

[0034] During the clamping process, the second telescopic drive component 225 begins to operate, extending and retracting at its output end, causing the connecting rod 224 to rotate around the support block 2212. The sliding groove at the top of the connecting rod 224 engages with the shaft at the end of the slide rod 223 away from the clamping component 222, while simultaneously, the sliding groove at the bottom of the connecting rod 224 engages with the shaft at the output end of the second telescopic drive component 225, thus causing the slide rod 223 and the clamping component 222 to move synchronously. Once the clamping component 222 has firmly clamped the sunroof guide rail, the operation of the synchronization assembly 21 and the second telescopic drive component 225 stops.

[0035] The synchronization component 21 includes a gear 213 disposed at the bottom of the main body 1. The synchronization component 21 also includes two racks 212 respectively connected to the support plate 221. The racks 212 mesh with the gears 213. The synchronization component 21 also includes a first telescopic drive member 211 fixed on the main body 1 and used to drive one of the racks 212.

[0036] After the cutting assembly 34 completes the cutting of the sunroof guide rail, the first telescopic drive component 211 begins to operate, driving the rack 212 to move linearly through its own telescopic movement. Since the rack 212 meshes with the gear 213, when one rack 212 moves, it drives the gear 213 to rotate, and the rotation of the gear 213 drives the other rack 212 to move in the opposite direction. The two racks 212 move simultaneously in opposite directions, causing the cut sunroof guide rail to separate to both sides. This synchronous separation design is not only simple and efficient to operate, but also ensures that the cut sunroof guide rail is separated, providing ample space for subsequent finishing operations such as grinding, and avoiding processing difficulties and quality problems caused by insufficient space.

[0037] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
