Description

Technical Field

[0001] This invention relates to the field of metalworking machine tool technology, specifically to a track-type linear beveling machine. Background Technology

[0002] Beveling machines are automated equipment used for beveling materials such as steel, cast iron, hard plastics, and non-ferrous metals before welding. They are mainly divided into two categories: pipe beveling machines and automatic flat beveling machines. The track linear beveling machine is one type of automatic flat beveling machine. This equipment adopts a two-stage clutch and motor integrated structure, and achieves frictionless processing through double ball flexible positioning technology. The equipment uses the rolling shear cutting principle for processing, and is equipped with limiters to guide the linear travel path. Some models are controlled by PLC technology to improve processing accuracy and efficiency, and non-standard customization can be made according to requirements.

[0003] Track-mounted beveling machines are widely used for cold milling of welded beveling in steel plates. However, since steel plates often have notched edges after blanking, existing beveling machines experience sudden load changes when milling steel plates with notched edges. This causes changes in cutting resistance at the notched position, resulting in tool imbalance. As the machine travels along the track, the instantaneous force changes on the cutting side, causing tool vibration and leading to local bending and offset of the beveling straightness. Furthermore, the instantaneous impact of recutting can easily damage the tool and reduce its service life.

[0004] Therefore, based on the above problems, we invented a track-type straight beveling machine. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a track-type linear beveling machine to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a track-type linear beveling machine, comprising a beveling machine body, wherein a polishing assembly and a track are mounted on the beveling machine body; The polishing assembly includes an L-shaped plate, a transmission assembly, a detection assembly, a synchronization assembly, and a polishing mechanism. The detection assembly and the transmission assembly are connected by a transmission mechanism. The synchronization component includes a frame, in which two second gears are rotatably mounted and meshed. A slide groove is provided on the top of the frame, and the transmission component is slidably mounted with the slide groove. The slide groove and the frame are fixedly connected by a connector. Both the transmission component and the track are provided with toothed grooves that mesh with the second gears. The polishing mechanism includes a mounting base installed on the transmission component, a second shaft rotatably mounted on the mounting base, a grinder and a third gear fixedly mounted on the second shaft, and an L-shaped rod installed on the detection component, the L-shaped rod having a tooth groove that meshes with the third gear.

[0007] Furthermore, the detection component includes a rod body one, which slides through an L-shaped plate and is equipped with a detection wheel. A rod body two is slidably passed through the L-shaped plate. The rod body one and the rod body two are connected by a transmission mechanism. A plate body three is fixedly connected to the lower end of the rod body two. The plate body three is slidably installed with the transmission component.

[0008] Furthermore, the transmission mechanism includes a plate three that is slidably mounted with the transmission assembly. A rod two is fixedly mounted on the upper end of the plate three. The rod two is slidably mounted through the L-shaped plate. A shaft one is mounted on the L-shaped plate. A first gear and a ratchet are coaxially mounted on the shaft one. The rod two has a tooth groove that meshes with the first gear. A reset groove is provided inside the rod one. A ratchet plate is slidably mounted in the reset groove. The ratchet plate has ratchet teeth that mesh with the ratchet. A cylinder is mounted on the rod one. The power shaft of the cylinder passes through the rod one and is fixedly connected to the ratchet plate.

[0009] Furthermore, the detection wheel is set at an angle.

[0010] Furthermore, the transmission component includes a vertical plate, a first plate, and a second plate. The second plate is fixedly connected to the upper end of the vertical plate, the first plate is fixedly connected to the lower end of the vertical plate, the second plate and the third plate are slidably installed, the mounting base is fixedly installed to the second plate, the slide groove is slidably installed to the first plate, the lower end of the first plate is provided with a toothed groove that meshes with the second gear, a U-shaped plate is vertically slidably installed outside the vertical plate, and the U-shaped plate is horizontally slidably installed to the L-shaped plate.

[0011] Furthermore, the shaft and the L-shaped plate are rotatably mounted together via a spiral spring.

[0012] Furthermore, a rod three is installed on the frame, and the rod three is slidably installed with the beveling machine body.

[0013] Furthermore, the second shaft is rotatably mounted to the mounting base via a spiral spring.

[0014] Furthermore, the ratchet teeth on the ratchet plate are arranged in an array and face upwards.

[0015] Furthermore, the parameters of the third gear and the second gear are the same.

[0016] Compared with the prior art, the present invention provides a track-type linear beveling machine, which has the following advantages: This invention uses an inclined detection wheel to identify notches on the edge of a steel plate in real time. By keeping the grinder stationary relative to the steel plate and polishing the inner wall of the notch, the notch can be pre-processed into a gentle transition slope. This allows the load on the tool to change slowly when cutting at the notch, effectively reducing processing vibration, avoiding bending and deviation of the bevel straightness, reducing tool wear from instantaneous impact, and extending tool life.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figure 1 A track-type linear beveling machine includes a beveling machine body 100, on which a polishing assembly 200 and a track 300 are mounted. It should be noted that the beveling machine body 100 is the overall load-bearing base of the equipment, undertaking the installation, positioning and load-bearing functions of various functional components, ensuring the stability of the overall operation of the equipment. The polishing component 200 is used to inspect and polish the notch on the edge of the steel plate to be beveling, so that a gentle slope chamfer is formed at the notch. When the beveling machine body 100 is cutting at the notch, the cutting tool gradually reduces the depth of cut and then gradually increases the depth of cut. The cutting load rises and falls smoothly, protecting the cutting tool, reducing tool wear and vibration, and preventing the bevel edge from bending and shifting.

[0021] like Figure 3 As shown, the polishing component 200 serves as a processing compensation component for the equipment. It is mainly used to adapt to the processing conditions of steel plate notch defects and to balance the equipment setup. Specifically, it includes an L-shaped plate body 210, a transmission component 220, a detection component 230, a synchronization component 240, and a polishing mechanism 250. The detection component 230 and the transmission component 220 are connected by a transmission mechanism. The transmission component 220 is used to support the polishing mechanism 250 and the detection component 230 to complete the overall displacement adjustment, thereby achieving adaptive processing position.

[0022] like Figure 3 As shown, the detection component 230 is used to detect the notch condition on the processed surface of the steel plate, providing a detection signal for subsequent polishing compensation. Specifically, it includes a rod 231, which slides through the L-shaped plate 210 and is equipped with a detection wheel 232. It should be noted that the detection wheel 232 is inclined, and the angle between the central axis of the detection wheel 232 and the horizontal plane is 45°. The inclined structure allows the detection wheel 232 to always be in contact with the edge of the steel plate, accurately detecting the notch on the edge of the steel plate. A return spring is installed between the rod 231 and the L-shaped plate 210. A position sensor is concealed on the detection wheel 232 to sense whether the position of the detection wheel 232 has changed. A rod 233 slides through the L-shaped plate 210, and the rod 231 and the rod 233 are connected by a transmission mechanism. The lower end of the rod 233 is fixedly connected to a plate 234, which is slidably installed with the transmission component 220.

[0023] It should be noted that the detection component 230 uses the detection wheel 232 to detect whether the steel plate has any gap defects in real time, and after detecting a defect, it transmits a defect signal to polish the gap position in advance to avoid instantaneous force imbalance of the tool.

[0024] like Figure 3 and Figure 7As shown, the transmission mechanism can achieve real-time linkage between detection and adjustment, and can adaptively adapt to defect conditions without manual intervention, thereby avoiding the problem of force imbalance caused by sudden changes in resistance at the notch. Specifically, it includes a plate 234 that is slidably installed with the transmission component 220. A rod 233 is fixedly installed at the upper end of the plate 234. The rod 233 slides through the L-shaped plate 210. A shaft 235 is installed on the L-shaped plate 210. It should be noted that the shaft 235 and the L-shaped plate 210 are rotatably installed through a spiral spring. The spiral spring can provide elastic reset torque to the shaft 235. After polishing, the shaft 235 automatically resets, realizing the cyclic operation of the structure. A first gear is coaxially installed on the shaft 235. 236 and ratchet 237, the second rod 233 is provided with a tooth groove that meshes with the first gear 236, the first rod 231 is provided with a reset groove, and a ratchet plate 238 is slidably installed in the reset groove. It should be noted that the ratchet plate 238 can slide horizontally back and forth along the inside of the reset groove to realize telescopic adjustment. The ratchet plate 238 is provided with ratchet teeth that mesh with the ratchet 237. It should be noted that the ratchet teeth on the ratchet plate 238 are arranged in an array and face upward. Through the one-way meshing of the ratchet 237 and the ratchet teeth, one-way locking and precise transmission of the transmission structure can be realized, avoiding adjustment deviation caused by reverse movement of the structure. A cylinder 239 is installed on the first rod 231. The power shaft of the cylinder 239 passes through the first rod 231 and is fixedly connected to the ratchet plate 238.

[0025] It should be noted that the transmission mechanism drives the ratchet plate 238 to extend and retract via the cylinder 239, which can precisely control the engagement and disengagement state of the ratchet 237. In conjunction with the return spring and the spiral spring, it ensures that the equipment can quickly return to the standard machining state after leaving the defective working condition, effectively improving the flexibility and stability of the equipment's working condition adaptation, avoiding sudden changes in tool load caused by instantaneous impact of the notch, and reducing the probability of tool damage.

[0026] like Figure 2 As shown, the transmission component 220 includes a vertical plate 221, a first plate 222, and a second plate 223. The second plate 223 is fixedly connected to the upper end of the vertical plate 221 to form an upper support mounting platform. The first plate 222 is fixedly connected to the lower end of the vertical plate 221 to form a lower sliding platform. The second plate 223 is slidably installed with the third plate 234. The mounting base 252 is fixedly installed with the second plate 223. The slide groove 242 is slidably installed with the first plate 222. The lower end of the first plate 222 is provided with a toothed groove that meshes with the second gear 244. A U-shaped plate 224 is vertically slidably installed outside the vertical plate 221. The U-shaped plate 224 is horizontally slidably installed with the L-shaped plate 210.

[0027] It should be noted that the vertical plate 221 is the main support frame of the transmission component 220, which plays the role of vertical load bearing and guidance. The transmission component 220 realizes the displacement adjustment of the overall structure through vertical and horizontal sliding, so that the equipment can simultaneously polish the notch of the steel plate while processing the bevel of the steel plate, without slowing down or even stopping the equipment, thus improving the processing efficiency of the equipment on the steel plate.

[0028] like Figure 5 As shown, the synchronization component 240 is used to realize the synchronous linkage of the walking and polishing operations of the beveling machine body 100, so that the equipment can polish and repair the notch position during the walking process, and compensate for the processing deviation caused by the notch defect. Specifically, it includes a frame 241, which adopts a frame structure, has high stability, and ensures the coaxiality and stability of the internal gear transmission. It should be noted that a rod 260 is installed on the frame 241, and the rod 260 is slidably installed with the beveling machine body 100. Two second gears 244 are rotatably installed inside the frame 241, and the two second gears 244 are meshed. A slide groove 242 is provided on the top of the frame 241, and the transmission component 220 is slidably installed with the slide groove 242. The slide groove 242 and the frame 241 are fixedly connected by a connector 243. It should be noted that the slide groove 242 and the frame 241 are connected as an integral structure by the connector 243. Both the transmission component 220 and the track 300 are provided with tooth grooves that mesh with the second gears 244.

[0029] Through the aforementioned technical features and the synchronous transmission structure of double gear meshing, the synchronous linkage between equipment track walking and polishing operation is achieved, ensuring that the equipment's walking speed and polishing adjustment rhythm are the same, and avoiding processing deviations caused by asynchronous processes.

[0030] like Figure 4 and Figure 6 As shown, the polishing mechanism 250 includes a mounting base 252 installed on the transmission component 220. The mounting base 252 serves as the fixed base of the polishing mechanism 250 and can be adjusted synchronously with the transmission component 220 to ensure accurate polishing position. A shaft 253 is rotatably mounted on the mounting base 252. It is worth mentioning that the shaft 253 and the mounting base 252 are rotatably mounted through a spiral spring. It should be noted that the spiral spring can provide a reset function for the shaft 253. After polishing, the shaft 253 returns to its initial position under the restoring force of the spiral spring. A grinding machine 251 and a third gear 254 are fixedly mounted on the shaft 253. An L-shaped rod 255 is installed on the detection component 230. The L-shaped rod 255 has a tooth groove that meshes with the third gear 254. It should be noted that the parameters of the third gear 254 and the second gear 244 are the same. When polishing the steel plate, the polishing machine 251 is kept relatively stationary with respect to the steel plate to accurately polish the notch.

[0031] Through the above technical features, the gear and rack meshing of the L-shaped rod 255 and the third gear 254 can convert the displacement adjustment of the detection component 230 into the angle fine adjustment of the grinder 251, polishing the notch of the steel plate and forming an inclined surface at the notch. When beveling the notch, the instantaneous change of the load on the tool is small, avoiding damage to the tool, extending the tool life, and avoiding tool vibration. The beveling effect at the notch is better.

[0032] Working principle: 1) Notch detection: When beveling the steel plate, the beveling machine body 100 moves and processes along the edge of the fixed steel plate. At this time, the detection wheel 232 rolls at the edge of the steel plate. When the detection wheel 232 rolls to the notch, the detection wheel 232 is suspended in the air. Under the action of the return spring, the rod 231 descends and drives the detection wheel 232 to descend, so that the detection wheel 232 abuts against the inside of the notch. At this time, the ratchet 237 slips on the ratchet teeth on the ratchet plate 238. At this time, the notch can be detected and the power supply of the grinding machine 251 is connected. 2) Polishing the notch: As the beveling machine body 100 continues to process the steel plate, the detection wheel 232 continues to advance forward and leave the notch. At this time, the detection wheel 232 moves upward relative to the L-shaped plate 210. The detection wheel 232 drives the rod 1 231 to rise and fall, and the rod 1 231 drives the ratchet plate 238 to rise and fall. The ratchet teeth on the ratchet plate 238 drive the ratchet wheel 237 to rotate. Under the coaxial action of the shaft 1 235, the ratchet wheel 237 drives the first gear 236 to rotate. The first gear 236 drives the rod 233 to fall. The rod 233 drives the synchronization component 240 to fall through the plate 3 234 and the transmission component 220. At this time, the second gear 244 located on the lower side of the synchronization component 240 meshes with the tooth groove on the track 300. It should be noted that at this time, the notch moves to the bottom of the grinding machine 251. Since the track 300 moves relative to the synchronization component 240, the tooth groove will drive the rotation of the gear. The second gear 244 rotates, and the two second gears 244 drive and move the first plate 222. The first plate 222 drives the second plate 223 to move through the vertical plate 221. The second plate 223 moves through the mounting base 252 and the grinding machine 251. It should be noted that the moving speed of the second plate 223 relative to the third plate 234 is the same as the moving speed of the beveling machine body 100 but in the opposite direction. That is, the relative position of the second plate 223 and the steel plate remains unchanged. Since the second plate 223 moves relative to the third plate 234, that is, the second plate 223 moves relative to the L-shaped rod 255, the L-shaped rod 255 drives the third gear 254 to rotate. The third gear 254 drives the grinding machine 251 to rotate around the central axis of the second shaft 253 through the shaft 253 until the grinding machine 251 rotates 180°. The grinding machine 251 can complete the polishing of the inner wall of the notch during the rotation process. 3) Reset: After the grinder 251 rotates 180°, the edge polishing work is completed. At this time, the cylinder 239 drives the ratchet plate 238 to move, so that the ratchet teeth on the ratchet plate 238 are separated from the ratchet wheel 237. The shaft 235 is reset under the action of the spiral spring. The grinder 251 rises and pulls away from the steel plate. The second gear 244 is separated from the tooth groove. At the same time, the grinder 251 is reset under the action of the spiral spring and rotates to the initial position. After the reset is completed, the cylinder 239 drives the ratchet plate 238 to reset, so that the ratchet teeth are engaged with the ratchet wheel 237, and the gap detection of the steel plate continues.
