Description

Technical Field

[0001] This invention belongs to the field of machining technology, specifically, it relates to a burr-free machining equipment and process for lightweight cable tray profiles. Background Technology

[0002] Lightweight cable trays are widely used in communications, power, and other fields. During the processing of their profiles, deburring the cut edges is a crucial step in ensuring product quality and installation safety. Currently, the deburring process for lightweight cable tray profiles still presents many inconveniences, resulting in low processing efficiency and difficulty in meeting the demands of mass production.

[0003] In existing technologies, the processing method for cutting and deburring lightweight cable tray profiles is usually quite cumbersome. The specific process is as follows: first, the profile is fixed by a clamping mechanism and a fixed-length cut is completed. After the cut is completed, the clamping mechanism must be unlocked and the position of the profile must be manually adjusted so that the cut surfaces at both ends of the profile are aligned with the grinding components. After the adjustment is in place, the clamping mechanism is locked again, and then the grinding components can be started to grind the profile cut surfaces, thereby achieving the synchronous grinding effect of the cut surfaces at both ends.

[0004] However, after each cutting, the unlocking-repositioning-locking operation needs to be repeated, which is cumbersome and takes up a lot of manual time. This not only increases the labor intensity of operators, but also significantly reduces the overall processing efficiency, making it difficult to meet the needs of mass production.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A lightweight cable tray profile cutting burr-free processing device includes a worktable with a base mounted on it. A pair of telescopic arms are rotatably mounted on the bottom of the worktable, and a connecting frame is inserted into each telescopic arm. A fixing block is mounted on the top of the connecting frame. A clamping component is mounted on one end of the fixing block, and a slider is inserted into the other end of the fixing block. A pair of switching guide rails are provided on the inner side wall of the base, and the switching guide rails are slidably connected to the side wall of the slider. The rotation directions of the pair of switching guide rails are different. When the telescopic arms rotate relative to each other, they drive the two fixing blocks to slide along different switching guide rails respectively, so that the cut workpieces are stacked vertically, which facilitates synchronous grinding and deburring. A cam is rotatably mounted on the bottom of the workbench, and the cam is used to drive the telescopic arm to deflect. A guide plate is inserted into the bottom of the worktable, and the guide plate fits against the guide block installed on the telescopic arm. The guide block has an inclined surface. The guide plate is slidably connected to a groove on the surface of the cam, and the groove has a ramp. When the cam rotates, the groove drives the guide plate to press the inclined surface, causing the telescopic arm to move outward, thereby driving the clamping assembly to slide to both sides first, so as to avoid interference with the workpiece during the rotation of the clamping assembly.

[0007] In a preferred embodiment of the present invention, the bottom of the workbench is provided with four support legs, the bottom of the four support legs is provided with anti-slip pads, the bottom of the support legs is provided with several pairs of reinforcing ribs, and the several pairs of reinforcing ribs are in the shape of a square. The workbench is also provided with a slide, and a grinding component is provided on the slide. The bottom of the workbench is provided with a collection frame, and the collection frame is used to collect grinding debris.

[0008] In a preferred embodiment of the present invention, the clamping assembly includes a fixing plate, the side wall of which is welded to the outer wall of the fixing block, and a clamping plate is vertically inserted into the outer wall of the fixing block. The side wall of the clamping plate and the fixing plate are locked together by the same screw, and the clamping plate and the fixing plate are used to clamp the workpiece. A boss is also installed on the worktable, and the bottom of the fixing plate overlaps the outer wall of the boss.

[0009] In a preferred embodiment of the present invention, a plug rod is installed on the slider, the plug rod is movably inserted into the side wall of the fixed block, and a compression spring is sleeved on the outer wall of the plug rod. One end of the compression spring is engaged with the side wall of the slider, and the other end of the compression spring is engaged with the outer wall of the fixed block.

[0010] In a preferred embodiment of the present invention, a positioning shaft is provided at the rotation center of the telescopic arm, the positioning shaft is rotatably connected to the bottom of the worktable, a swing arm is rotatably mounted on the outer wall of the telescopic arm, a fixed frame is rotatably mounted on the swing arm, a top rod is mounted on the fixed frame, the top rod is horizontally inserted into the worktable, and a limit plate is installed at the end of the top rod, the end of the limit plate is chamfered, and the arc surface of the limit plate fits against the outer wall of the cam. The outer wall of the cam is also provided with an arc surface, and when the arc surface separates from the top rod, the groove corresponds to the guide plate.

[0011] In a preferred embodiment of the present invention, a limiting seat is installed at the bottom of the workbench, the push rod passes through the limiting seat, and a limiting spring is sleeved on the outer wall of the push rod. One end of the limiting spring is engaged with the side wall of the limiting seat, and the other end of the limiting spring is engaged with the side wall of the limiting plate. The limiting spring is used to drive the side wall of the push rod to fit against the side wall of the cam.

[0012] In a preferred embodiment of the present invention, a drive motor is mounted on the worktable, and a transmission shaft is mounted on the output end of the drive motor. The transmission shaft movably passes through the worktable, and the end of the transmission shaft is connected to the rotation center of the cam.

[0013] In a preferred embodiment of the present invention, a bracket is installed on the guide plate, a slide plate is installed on the side wall of the bracket, a slide rod is movably installed through the slide plate, the bottom of the slide rod is installed on the workbench, a pressure plate is installed on the top of the slide rod, and a compression spring is sleeved on the slide rod. One end of the compression spring is engaged with the pressure plate, and the other end of the compression spring is engaged with the slide plate.

[0014] In a preferred embodiment of the present invention, a timing frame is mounted on the bracket, a push rod is mounted on the timing frame, and the end of the push rod is in contact with the surface of the groove. The compression spring is used to drive the push rod to correspond with the groove.

[0015] A burr-free machining process for lightweight cable tray profiles includes the following steps: Step 1: Check the stability of the support legs and anti-slip pads at the bottom of the workbench, confirm that the reinforcing ribs are firmly connected, and ensure that the limit springs, compression springs, and squeeze springs are in normal elasticity. Step 2: The operator places the lightweight cable tray profile to be processed between the fixed plate and the clamping plate, adjusts the position of the profile to be cut, and locks the clamping plate and the fixed plate by tightening the bolts to firmly clamp the profile. Step 3: Start the external cutting mechanism to perform a fixed-length cutting operation on the clamped and fixed profile. The debris generated during the cutting process will fall naturally and be collected by the collection box at the bottom of the workbench. After the cutting is completed, turn off the external cutting mechanism and wait for the subsequent relocation operation. Step 4: Profile shifting and adjustment. Start the drive motor. The drive motor drives the cam to rotate through the transmission shaft. The arc-shaped surface of the outer wall of the cam gradually separates from the push rod. The groove on its surface corresponds to the push rod on the guide plate. The compression spring drives the guide plate to move to the bottom of the worktable. The guide plate presses the inclined surface on the guide block, pushing the telescopic arm to move outward around the positioning axis. This drives the connecting frame, fixing block and clamping assembly to move outward synchronously. Due to the different rotation directions of the switching guide rails, the telescopic arms at both ends drive the corresponding clamping assemblies and profiles to rotate upward and downward respectively. Finally, the profiles at both ends rotate to the same vertical plane, in a vertically stacked state, with the profile cut facing the grinding assembly. Step 5: Grinding and finishing the cut edges. Activate the grinding component on the slide block. The grinding component simultaneously grinds the cut edges of the vertically stacked profiles to remove burrs and flash. The waste generated during grinding falls into the collection box for centralized processing.

[0016] Compared with the prior art, the present invention has the following advantages: This invention integrates profile clamping, fixed-length cutting, displacement adjustment, and simultaneous grinding and deburring processes through the coordinated linkage of components such as cams, telescopic arms, and guide plates. It eliminates the need for frequent manual transfer of profiles and uses switching guides with different rotation directions to quickly rotate the cut profiles to the same vertical plane for stacking. The grinding component can simultaneously process multiple profile cuts, significantly shortening the processing cycle and effectively solving the problems of disconnected and inefficient traditional processing processes, thereby improving the batch processing efficiency of lightweight cable tray profiles.

[0017] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0021] Example 1:

[0022] like Figures 1 to 7 As shown, a lightweight cable tray profile cutting burr-free processing equipment includes a workbench 1, a base 5 mounted on the workbench 1, a pair of telescopic arms 16 rotating at the bottom of the workbench 1, and a connecting frame 15 inserted into each telescopic arm 16. A fixing block 8 is mounted on the top of the connecting frame 15. A clamping component is mounted on one end of the fixing block 8, and a slider 7 is inserted into the other end of the fixing block 8. A pair of switching guide rails 6 are provided on the inner side wall of the base 5, and the switching guide rails 6 are slidably connected to the side wall of the slider 7. The rotation directions of the pair of switching guide rails 6 are different. When the telescopic arms 16 rotate relative to each other, they drive the two fixing blocks 8 to slide along different switching guide rails 6 respectively, so that the cut workpieces are stacked vertically, which is convenient for synchronous grinding and deburring. A cam 24 is rotatably mounted on the bottom of the workbench 1, and the cam 24 is used to drive the telescopic arm 16 to deflect. A guide plate 28 is inserted into the bottom of the worktable 1, and the guide plate 28 fits against the guide block 29 installed on the telescopic arm 16. The guide block 29 has an inclined surface 30. The guide plate 28 is slidably connected to the groove 38 on the surface of the cam 24, and the groove 38 has a ramp. When the cam 24 rotates, the groove drives the guide plate 28 to press the inclined surface, causing the telescopic arm 16 to move outward, thereby driving the clamping assembly to slide to both sides first, so as to avoid interference with the workpiece during the rotation of the clamping assembly.

[0023] like Figures 1 to 7 As shown in the specific embodiment, the workbench 1 has four support legs 2 installed at its bottom, with anti-slip pads on the bottom of each support leg 2. Several pairs of reinforcing ribs 3 are also installed on the bottom of each support leg 2, and these reinforcing ribs 3 are U-shaped. A slide 39 is also installed on the workbench 1, and a grinding component is mounted on the slide 39. A collection frame 4 is installed at the bottom of the workbench 1 to collect grinding debris. The four support legs 2 ensure the stability of the workbench 1, the anti-slip pads prevent slippage during operation, the U-shaped reinforcing ribs 3 enhance the structural strength of the support legs 2 and extend the service life of the equipment, the slide 39 allows the grinding component to move flexibly to adapt to grinding needs in different positions, and the collection frame 4 collects debris in a concentrated manner, keeping the processing environment clean and facilitating debris recycling.

[0024] like Figures 1 to 7As shown, the clamping assembly further includes a fixing plate 11. The sidewall of the fixing plate 11 is welded to the outer wall of the fixing block 8. A clamping plate 12 is vertically inserted into the outer wall of the fixing block 8. The sidewall of the clamping plate 12 is locked to the fixing plate 11 by the same tightening bolt 13. The clamping plate 12 and the fixing plate 11 are used to clamp the workpiece. A boss 14 is also installed on the worktable 1, and the bottom of the fixing plate 11 overlaps the outer wall of the boss 14. The fixing plate 11 and the clamping plate 12 are locked by the tightening bolt 13, which can achieve a firm clamping of profiles of different specifications. The welded connection between the fixing plate 11 and the fixing block 8 ensures the structural stability of the clamping assembly. The boss 14 can support the fixing plate 11, ensuring the horizontal stability of the profile in the clamping state, avoiding profile displacement during cutting, and improving processing accuracy.

[0025] Example 2:

[0026] The difference between the above embodiments and this embodiment is that: Figures 1 to 7 As shown, a rod 9 is installed on the slider 7, and the rod 9 is movably inserted into the side wall of the fixed block 8. A compression spring 10 is sleeved on the outer wall of the rod 9, with one end of the compression spring 10 engaged with the side wall of the slider 7 and the other end engaged with the outer wall of the fixed block 8. The movable engagement between the rod 9 and the fixed block 8 enables a flexible connection between the slider 7 and the fixed block 8. The compression spring 10 provides buffering and adaptive adjustment when the slider 7 slides along the switching guide rail 6, avoiding rigid collisions during slider 7 sliding, ensuring smooth movement of the fixed block 8 and clamping components, reducing component wear, and extending the service life of the equipment.

[0027] like Figures 1 to 7 As shown, in a specific embodiment, a positioning shaft 17 is provided at the rotation center of the telescopic arm 16. The positioning shaft 17 is rotatably connected to the bottom of the worktable 1. A swing arm 18 is rotatably mounted on the outer wall of the telescopic arm 16. A fixed frame 19 is rotatably mounted on the swing arm 18. A top rod 20 is mounted on the fixed frame 19. The top rod 20 is horizontally inserted into the worktable 1. A limit plate 23 is installed at the end of the top rod 20. The end of the limit plate 23 is chamfered. The arc surface of the limit plate 23 fits against the outer wall of the cam 24. The outer wall of the cam 24 is also provided with an arc surface 27. When the arc surface 27 separates from the top rod 20, the groove 38 corresponds to the guide plate 28. The positioning shaft 17 can serve as the rotation fulcrum of the telescopic arm 16, ensuring the precise deflection of the telescopic arm 16. The rotational connection between the swing arm 18 and the fixed frame 19 enables flexible linkage between the displacement of the top rod 20 and the deflection of the telescopic arm 16. The arc surface of the limiting plate 23 fits against the cam 24 to ensure linkage stability. The chamfering treatment reduces wear on the limiting plate 23 and the cam 24. The arc surface 27 can limit the top rod 20 during the cutting stage, ensuring that the clamping assembly maintains its initial position and ensuring cutting accuracy.

[0028] like Figures 1 to 7As shown, furthermore, a limiting seat 21 is installed at the bottom of the worktable 1. The push rod 20 passes through the limiting seat 21. A limiting spring 22 is sleeved on the outer wall of the push rod 20. One end of the limiting spring 22 is engaged with the side wall of the limiting seat 21, and the other end is engaged with the side wall of the limiting plate 23. The limiting spring 22 is used to drive the side wall of the push rod 20 to fit against the side wall of the cam 24. The limiting seat 21 can guide and limit the movement of the push rod 20, preventing the push rod 20 from deviating. The elastic force of the limiting spring 22 can always push the limiting plate 23 to fit tightly against the outer wall of the cam 24, ensuring that the push rod 20 can be accurately driven to move when the cam 24 rotates, ensuring the reliability of the linkage and avoiding the phenomenon of linkage jamming.

[0029] Example 3:

[0030] The difference between the above embodiments and this embodiment is that: Figures 1 to 7 As shown, a drive motor 25 is installed on the worktable 1, and a transmission shaft 26 is installed at the output end of the drive motor 25. The transmission shaft 26 movably passes through the worktable 1, and its end is connected to the rotation center of the cam 24. The drive motor 25 provides a stable driving force, which is precisely transmitted to the cam 24 through the transmission shaft 26, causing the cam 24 to rotate at a uniform speed. This ensures the synchronization of the cam 24 with other components, thereby ensuring that the outward movement and deflection of the telescopic arm 16 are precise and controllable, and improving the stability and consistency of the equipment processing.

[0031] like Figures 1 to 7 As shown, in a specific embodiment, a bracket 31 is installed on the guide plate 28, a slide plate 32 is installed on the side wall of the bracket 31, a slide rod 33 is movably installed through the slide plate 32, the bottom of the slide rod 33 is installed on the worktable 1, a pressure plate 34 is installed on the top of the slide rod 33, and a compression spring 35 is sleeved on the slide rod 33. One end of the compression spring 35 is engaged with the pressure plate 34, and the other end of the compression spring 35 is engaged with the slide plate 32. The bracket 31 can achieve a firm connection between the guide plate 28 and the slide plate 32. The slide rod 33 can guide the movement of the slide plate 32, ensuring that the vertical movement of the guide plate 28 is stable. The pressure plate 34 can limit the compression spring 35. The elastic force of the compression spring 35 can drive the slide plate 32 to move the guide plate 28 downward, ensuring that the guide plate 28 and the inclined surface 30 of the guide block 29 are tightly fitted, ensuring smooth compression transmission.

[0032] like Figures 1 to 7As shown, a synchronization frame 36 is further mounted on the bracket 31, and a push rod 37 is mounted on the synchronization frame 36. The end of the push rod 37 is in contact with the surface of the groove 38. A compression spring 35 is used to drive the push rod 37 to correspond with the groove 38. The synchronization frame 36 ensures that the push rod 37 and the guide plate 28 move synchronously. The contact between the push rod 37 and the groove 38 enables precise linkage between the rotation of the cam 24 and the movement of the guide plate 28. The compression spring 35 drives the push rod 37 to always be in contact with the groove 38, avoiding the phenomenon of linkage disengagement, ensuring that the guide plate 28 can respond to the rotation of the cam 24 in a timely manner, and ensuring smooth connection of equipment processes.

[0033] This invention also discloses a burr-free machining process for lightweight cable tray profiles, the steps of which are as follows: Step 1: Check the stability of the bottom support leg 2 and anti-slip pad of the workbench 1, confirm that the reinforcing rib 3 is firmly connected, and ensure that the limit spring 22, compression spring 10 and squeeze spring 35 are in normal elastic state. Step 2: The operator places the lightweight cable tray profile to be processed between the fixed plate 11 and the clamping plate 12, adjusts the position of the profile to be cut, and locks the clamping plate 12 and the fixed plate 11 by tightening the bolts 13 to firmly clamp the profile. Step 3: Start the external cutting mechanism to perform a fixed-length cutting operation on the clamped and fixed profile. The debris generated during the cutting process will fall naturally and be collected by the collection box 4 at the bottom of the workbench 1. After the cutting is completed, turn off the external cutting mechanism and wait for the subsequent relocation operation. Step 4: Profile shifting and adjustment. Start the drive motor 25. The drive motor 25 drives the cam 24 to rotate through the transmission shaft 26. The arc surface 27 of the outer wall of the cam 24 gradually separates from the push rod 20. The groove 38 on its surface corresponds to the push rod 37 on the guide plate 28. The compression spring 35 drives the guide plate 28 to move towards the bottom of the worktable 1. The guide plate 28 compresses the inclined surface 30 on the guide block 29, pushing the telescopic arm 16 to move outward around the positioning shaft 17. This drives the connecting frame 15, the fixing block 8, and the clamping assembly to move outward synchronously. Due to the different rotation directions of the switching guide rail 6, the telescopic arms 16 at both ends drive the corresponding clamping assembly and profile to rotate upward and downward respectively. Finally, the profiles at both ends rotate to the same vertical plane and are in a vertically stacked state, with the profile cut facing the grinding assembly. Step 5: Grinding and finishing the cuts. Start the grinding component on the slide 39. The grinding component grinds the cuts of the vertically stacked profiles simultaneously to remove burrs and flash. The waste generated by grinding falls into the collection box 4 for centralized processing.

[0034] The implementation principle of the lightweight cable tray profile burr-free cutting processing equipment of the present invention is as follows: During operation, the cable tray profile to be processed is first stably clamped and fixed by the clamping assembly. The operator places the profile between the fixing plate 11 and the clamping plate 12, and locks the clamping plate 12 and the fixing plate 11 by tightening the bolts 13, so that the profile is firmly clamped. The bottom of the fixing plate 11 overlaps on the boss 14 to ensure the horizontal stability of the profile in the clamping state, providing a foundation for subsequent cutting operations. At this time, the profile is in the cutting position, completing the positioning and fixing process of the profile.

[0035] After the profile is clamped, the external cutting mechanism performs a fixed-length cutting operation on the profile, and the debris generated by the cutting can be collected by the collection box 4 at the bottom of the worktable 1.

[0036] After cutting, the drive motor 25 starts and drives the cam 24 to rotate through the transmission shaft 26. During the rotation of the cam 24, the arc surface 27 of its outer wall gradually separates from the top rod 20. The groove 38 on the surface of the cam 24 corresponds to the push rod 37 on the guide plate 28. The compression spring 35 drives the guide plate 28 to move towards the bottom of the worktable 1 through the pressure plate 34, slide rod 33, slide plate 32 and bracket 31. The guide plate 28 and the inclined surface 30 on the guide block 29 press against each other, pushing the telescopic arm 16 to move outward around the positioning shaft 17. This drives the connecting frame 15, the fixing block 8 and the clamping assembly to move outward synchronously, avoiding interference between the clamping assembly and the structure on the worktable 1 when the profile is rotated, and ensuring smooth profile displacement.

[0037] After the guide plate 28 completes the lateral movement of the telescopic arm 16, the cam 24 continues to rotate. Through the contact and linkage between its outer wall and the limiting plate 23, the cam 24 drives the deflection of the telescopic arm 16. The specific linkage process is as follows: When the cam 24 rotates, the contour change of its outer wall will push the limiting plate 23 to produce displacement. The limiting plate 23 is fixedly connected to the push rod 20, which in turn drives the push rod 20 to reciprocate within the limiting seat 21. The other end of the push rod 20 is connected to the fixing frame 19, which in turn is connected to the telescopic arm 16. The swing arm 18 is rotatably connected, so the displacement of the top rod 20 is transmitted to the telescopic arm 16 through the fixed frame 19 and the swing arm 18, driving a pair of telescopic arms 16 to deflect relative to each other around the positioning shaft 17. Since the rotation directions of a pair of switching guide rails 6 are different, the deflection directions of the two telescopic arms 16 are opposite: one end of the telescopic arm 16 drives the corresponding connecting frame 15, fixed block 8 and clamping assembly to rotate downward, while the other end of the telescopic arm 16 drives the corresponding connecting frame 15, fixed block 8 and clamping assembly to rotate upward.

[0038] During this deflection process, the top rod 20 always moves flexibly within the limit seat 21 in coordination with the movement trajectory of the telescopic arm 16, and the elastic force of the limit spring 22 always pushes the limit plate 23 to fit tightly against the outer wall of the cam 24, ensuring the linkage stability between the cam and the telescopic arm, thereby ensuring that the entire rotation process is smooth and without jamming; at the same time, the slider 7 at one end of the fixed block 8 slides in cooperation with the switching guide rail 6 on the inner wall of the base 5, and the two sliders 7 slide in a direction along their respective corresponding rotation guide rails. The insertion rod 9 and the compression spring 10 provide buffering and adaptive adjustment during the sliding process, further ensuring that the fixed block 8 moves smoothly, and finally drives the two sets of clamping components and the cutting profiles they clamp to move synchronously, so that the profiles at both ends rotate to the same vertical plane, in a vertically stacked state, and the profile cuts are uniformly facing the location of the grinding component.

[0039] Once the profiles are in place, the slide 39 on the workbench 1 drives the grinding component to simultaneously grind and deburr the vertically stacked profile cuts, removing burrs and flash from the cuts to ensure smooth and flat profile cuts. Waste generated during the grinding process also falls into the collection box 4 for centralized processing, completing a continuous operation of cutting, shifting, and grinding to remove burrs.

[0040] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

10. A burr-free machining process for lightweight cable tray profiles, characterized in that, The lightweight cable tray profile burr-free cutting processing equipment according to any one of claims 1 to 9, and the lightweight cable tray profile burr-free cutting processing process, comprises the following steps: Step 1: Check the stability of the bottom support legs (2) and anti-slip pads of the workbench (1), confirm that the reinforcing ribs (3) are firmly connected, and ensure that the limit springs (22), compression springs (10), and squeeze springs (35) are in normal elasticity. Step 2: The operator places the lightweight cable tray profile to be processed between the fixed plate (11) and the clamping plate (12), adjusts the position of the profile so that it is in the cutting position, and locks the clamping plate (12) and the fixed plate (11) by tightening the bolts (13) so that the profile is firmly clamped. Step 3: Start the external cutting mechanism to perform a fixed-length cutting operation on the clamped and fixed profile. The debris generated during the cutting process falls naturally and is collected by the collection box (4) at the bottom of the workbench (1). After the cutting is completed, turn off the external cutting mechanism and wait for the subsequent relocation operation. Step 4: Profile shifting and adjustment. Start the drive motor (25). The drive motor (25) drives the cam (24) to rotate through the transmission shaft (26). The arc surface (27) of the outer wall of the cam (24) gradually separates from the top rod (20). The groove (38) on its surface corresponds to the push rod (37) on the guide plate (28). The compression spring (35) drives the guide plate (28) to move towards the bottom of the worktable (1). The guide plate (28) compresses the inclined surface (30) on the guide block (29), pushing the telescopic arm (16) to move outward around the positioning shaft (17) as the center, driving the connecting frame (15), the fixing block (8) and the clamping assembly to move outward synchronously. Due to the different rotation directions of the switching guide rail (6), the telescopic arms (16) at both ends drive the corresponding clamping assembly and profile to rotate upward and downward respectively, so that the profiles at both ends rotate to the same vertical plane, in a vertical stacked state, and the profile cut faces the grinding assembly. Step 5: Grinding the cut to remove burrs and finish the cut. Start the grinding component on the slide (39). The grinding component grinds the cut of the vertically stacked profiles simultaneously to remove burrs and flash at the cut. The waste generated by grinding falls into the collection box (4) for centralized processing.
