Description

[0001] This invention relates to the field of cutting and processing technology, specifically a crossbeam assembly that can adjust its processing position back and forth during cutting and processing. Background Technology

[0002] In cutting processes, a crossbeam assembly capable of adjusting the processing position typically includes a movable crossbeam that can move along the processing direction on the machine tool bed to accommodate the processing requirements of materials of different lengths. In the prior art, gears can be installed on the crossbeam assembly, and racks can be installed on both sides of the machine tool. The crossbeam can move back and forth along the machine tool through the meshing transmission of the racks and gears, thereby achieving the purpose of adjusting the processing position.

[0003] However, the racks on both sides of the machine tool are always exposed to the air. If dust is generated during the production process, the dust will gradually fall into the gap between the adjacent teeth of the rack. Over time, a large amount of dust will accumulate. When the equipment is processing, the gears will come into contact with the dust as they move along the rack. The presence of dust will increase the friction between the gear and rack contact surfaces, further aggravating the wear.

Detailed Implementation

[0029] Please see Figures 1-11In this embodiment of the invention, a crossbeam assembly capable of adjusting the processing position during cutting includes a machine tool 1. A bed rack 2 is axially symmetrically arranged on both sides of the machine tool 1. Side frames 3 are axially symmetrically slidably arranged on both sides of the machine tool 1. Rotating gears 4 and transmission gears 5 are rotatably arranged within each of the two side frames 3. The rotating gears 4 and transmission gears 5 are connected by a belt 6. The rotating gears 4 mesh with the bed rack 2. The two transmission gears 5 are connected by a spindle 7. A drive gear 8 is rotatably arranged within one of the side frames 3, meshing with one of the transmission gears 5. Multiple cleaning components 9 are arranged on one side of the bed rack 2 on the machine tool 1. A drive rack 10 is arranged at the bottom of the side frame 3 and is connected to the cleaning components 9. The two side frames 3 are connected by a crossbeam. Processing components can be arranged on the crossbeam, and these components can move laterally, rotate, vibrate, etc., on the crossbeam to process objects placed on the machine tool 1. The machine tool employs a variety of processing methods. Starting the motor of drive gear 8 causes drive gear 5 to rotate, which in turn drives belt 6 and the rotating gear 4 on the same side. Simultaneously, the rotation of transmission gear 5 drives spindle 7, which in turn drives transmission gear 5, belt 6, and rotating gear 4 on the other side. Rotating gear 4 meshes with bed rack 2, enabling the side frame 3 and crossbeam to move back and forth along the machine tool 1, allowing for adjustment of the processing position. Since bed rack 2 is constantly exposed to air, dust in the workshop gradually accumulates in the gaps between adjacent teeth. During rotation, the presence of dust increases wear on rotating gear 4, affecting the transmission accuracy and service life of rotating gear 4 and bed rack 2. Therefore, drive rack 10 can be installed at the bottom of side frame 3. Drive rack 10 first engages with the front cleaning component 9, causing the cleaning component 9 to clean bed rack 2. After removing dust, rotating gear 4 then contacts bed rack 2, reducing wear. Multiple cleaning components 9 are provided, each corresponding to the gaps between adjacent teeth of bed rack 2.

[0030] See Figures 6-10As shown, in this embodiment, preferably, the cleaning component 9 includes a movable frame 91. Cleaning plates 92 are axially symmetrically and movably arranged on both sides of the movable frame 91. A connecting rod 93 is movably connected to one side of the cleaning plate 92 via a ball joint. A horizontal plate 94 is fixedly connected to the end of the connecting rod 93 away from the cleaning plate 92. A fixed plate 95 is fixedly arranged above the horizontal plate 94. A movable plate 96 is laterally and movably arranged through the center of the fixed plate 95. One end of the movable plate 96 is fixedly connected to the cleaning plate 92. In the initial state, the movable frame 91 is in contact with the bottom of the gap between adjacent teeth of the bed rack 2. The length of the movable frame 91 is less than the length of the gap. When cleaning is required, the movable frame 91 moves upward. During the upward movement of the movable frame 91 along the gap, the cleaning plates 92 move outward from the movable frame 91. The cleaning plates 92 on both sides move to the outside. Initially, the cleaning plates 92 are vertically arranged within the movable frame 91. After moving to the outside, the cleaning plates 92 move laterally. The movable plate 96 is located above the connecting rod 93. The connecting rod 93 is movably connected to the central ball joint of the cleaning plate 92. The movement of the movable plate 96 along the fixed plate 95 will cause the cleaning plate 92 to rotate clockwise, so that the cleaning plates 92 on both sides maintain the same inclination angle with the racks on both sides of the interval. That is, the lateral movement of the movable plate 96 will cause the cleaning plate 92 to rotate. The cleaning plate 92 can be adjusted in angle relative to the connecting rod 93. After the inclination is the same, the movable plate 96 will no longer move. The cleaning plate 92 will abut against the two sides of the interval. The movable frame 91 continues to move upward, and the cleaning plate 92 will also gradually move to both sides to ensure that it always abuts against the two sides of the interval. During the upward movement of the movable frame 91, the interval can be cleaned and dust removed. When the movable frame 91 moves to the highest point of the interval, it moves to one side. Then the rotating gear 4 meshes with the rack 2 of the bed in this part. It will not affect the movement of the rotating gear 4. The horizontal plate 94 provides support for the fixed plate 95 and the connecting rod 93.

[0031] See Figures 9-10 As shown, in this embodiment, preferably, the center of the moving plate 96 has an inclined groove 961, and a lifting plate 11 is movably disposed in the inclined groove 961. A lifting rod 12 is fixedly connected to the bottom of the lifting plate 11, and the end of the lifting rod 12 away from the lifting plate 11 movably passes through the fixed plate 95 and the horizontal plate 94. When the moving frame 91 moves upward along the interval and the cleaning plates 92 on both sides move outward from the moving frame 91, the lifting rod 12 moves downward. The downward movement of the lifting rod 12 will drive the lifting plate 11 to move downward. With the cooperation between the lifting plate 11 and the inclined groove 961 of the moving plate 96, the moving plate 96 can drive the cleaning plate 92 to rotate clockwise, so that the tilt angle of the cleaning plate 92 matches the two sides of the interval. The cleaning plate 92 can fit more tightly with the two sides of the interval, which can improve the cleaning effect on the bed rack 2. In this step, the vertical movement of the lifting rod 12 can adjust the angle of the cleaning plate 92 so that it can match the two sides of the interval.

[0032] See Figures 7-9 As shown, in this embodiment, preferably, a vertical plate 13 is fixedly connected to one side of the horizontal plate 94, and a rotating rod 14 is movably connected through the vertical plate 13. A cam 15 is fixedly sleeved on the outer side of the rotating rod 14, and the cam 15 is fixedly connected to the lifting rod 12. When the moving frame 91 moves intermittently upward and the cleaning plates 92 on both sides move outward from the moving frame 91, the rotating rod 14 is rotated. The rotating rod 14 rotates at a certain angle, which can drive the cam 15 to rotate. The rotation of the cam 15 can drive the lifting rod 12 to move downward, thereby driving the moving plate 96 to move laterally, so that the cleaning plate 92 rotates clockwise to adjust the tilt angle of the cleaning plate 92. The vertical plate 13 provides support for the rotating rod 14.

[0033] See Figures 7-9 As shown, in this embodiment, preferably, a limiting groove 141 is formed on the outer side of the rotating rod 14. The limiting groove 141 consists of two straight grooves and one curved groove. A limiting rod 16 is movably fitted inside the limiting groove 141, and one end of the limiting rod 16 is fixedly connected to the inner wall of the moving frame 91. When the cleaning plate 92 moves outward along the moving frame 91, it will drive the horizontal plate 94, the vertical plate 13, and the rotating rod 14 to move synchronously. In the initial state, the limiting rod 16 is fitted with one of the straight grooves. During this process, the rotating rod 14 will not rotate. That is, the cleaning plate 92 moves to the outside of the moving frame 91 in this short time. Then, the curved groove section of the limiting groove 141 formed by the rotating rod 14 fits with the limiting rod 16, thereby driving the cleaning plate 92 to move outward. Rotating rod 14 rotates, which in turn drives cam 15 to rotate, causing cleaning plate 92 to tilt. Once the tilt angle of cleaning plate 92 is determined, it will fit against the two sides of the intermittent. Since the two sides of the intermittent are tilted, forming an inverted trapezoidal shape, the moving frame 91 must keep moving cleaning plate 92 to both sides during the upward movement to ensure that cleaning plate 92 always fits against the two sides of the intermittent. This ensures cleaning efficiency. During this process, limiting rod 16 fits against another straight section of limiting groove 141, and rotating rod 14 will not rotate. Through the cooperation of limiting groove 141 and limiting rod 16, the tilt angle of cleaning plate 92 can be adjusted when it moves to both sides of the intermittent, allowing it to fit more tightly against the intermittent.

[0034] See Figures 5-7As shown, in this embodiment, preferably, a crossbar 17 is movably disposed within the movable frame 91, and a first gear 18 is fixedly sleeved on the outside of the crossbar 17. First racks 19 are meshed and driven on both the upper and lower sides of the first gear 18. The first racks 19 are fixedly connected to the vertical plate 13, and the two first racks 19 are slidably connected to the upper and lower inner walls of the movable frame 91, respectively. When the movable frame 91 is moved upward, the crossbar 17 is rotated, and the rotation of the crossbar 17 drives the first gear 18 to rotate. The rotation of the first gear 18 drives the two first racks 19 to move to both sides, thereby driving the vertical plate 13, rotating rod 14, crossbar 94, cam 15, and cleaning plate 92 on both sides to move synchronously. During the movement, the cleaning plate 92 will synchronously adjust its tilt angle as it moves towards the intermittent side.

[0035] See Figures 6-7 As shown, in this embodiment, preferably, a sleeve 20 is fixedly provided on the outer side of the movable frame 91, and the crossbar 17 movably passes through the sleeve 20. A notch 201 is provided on the outer side of the sleeve 20, and a second gear 21 is fixedly sleeved on the crossbar 17 at the notch 201. A second rack 22 is fixedly provided on one side of the bed rack 2 of the machine tool 1, and the second gear 21 meshes with the second rack 22 for transmission. When the sleeve 20 and the movable frame 91 are moved upward, the crossbar 17 and the second gear 21 will be driven upward during the movement. The movement of the frame 91 engages with the second rack 22. The rotation of the second gear 21 within the notch 201 causes the crossbar 17 to rotate. The rotation of the crossbar 17 causes the first gear 18 to rotate, thereby moving the cleaning plate 92. This allows the cleaning plate 92 to contact both sides of the intermittent area. As the frame 91 continues to move upward, the second gear 21 continues to engage with the second rack 22, causing the cleaning plate 92 to continue moving towards the side of the intermittent area during its ascent. This ensures that the cleaning plate 92 remains in contact with the side of the intermittent area, improving the cleaning quality of the intermittent dust.

[0036] See Figure 11As shown, in this embodiment, preferably, a movable rod 23 is fixedly connected to the side of the sleeve 20 away from the movable frame 91. A movable plate 24 is movably sleeved on the outside of the movable rod 23, and a movable frame 25 is fixedly connected to its end. A limiting frame 26 is movably sleeved on the outside of the movable plate 24, and the limiting frame 26 is fixedly connected to the machine tool 1. A rotating plate 27 is movably arranged inside the movable frame 25. Rotating the rotating plate 27 will cause the movable frame 25 to move upward first. The upward movement of the movable frame 25 will cause the movable rod 23 and the movable plate 24 to move upward simultaneously. The upward movement of the movable rod 23 will cause the sleeve 20 to move upward. The upward movement of the movable frame 91 allows the cleaning plate 92 to clean the intermittent dust. Continuous rotation of the rotating plate 27 will drive the movable frame 25 to move to the highest point and then move away from the bed rack 2. The lateral movement of the movable frame 25 will drive the movable rod 23 to move laterally along the movable plate 24, thereby moving the movable frame 91 to one side to avoid collision with the rotating gear 4. The limiting frame 26 is to ensure the stability of the up and down movement of the movable plate 24. In this step, the cooperation between the rotating plate 27 and the movable frame 25 enables the movable frame 91 to first move upward to clean the intermittent dust, and then move to one side to avoid collision with the rotating gear 4.

[0037] See Figure 11 As shown, in this embodiment, preferably, the machine tool 1 is fixedly provided with a positioning plate 28 on one side of the rotating plate 27. A round rod 29 is movably passed through the positioning plate 28, and one end of the round rod 29 is fixedly connected to the rotating plate 27. A first bevel gear 30 is fixedly provided at the other end of the round rod 29. A rotating shaft 31 is rotatably connected to one side of the positioning plate 28. A second bevel gear 32 is fixedly sleeved on the outside of the rotating shaft 31. The first bevel gear 30 and the second bevel gear 32 mesh and transmit power. Rotating the rotating shaft 31 causes the second bevel gear 32 to rotate, thereby causing the first bevel gear 30 and the round rod 29 to rotate. The rotation of the round rod 29 causes the rotating plate 27 to rotate. The rotation of the rotating plate 27 causes the movable frame 25 to move upward, realizing that the movable frame 91 moves upward first and then laterally. The positioning plate 28 provides support for the round rod 29.

[0038] See Figure 4 and Figure 11As shown, in this embodiment, preferably, a third gear 33 is fixedly provided at the end of the rotating shaft 31. The third gear 33 meshes with the drive rack 10 for transmission. When it is necessary to adjust the position of the crossbeam and the side frame 3, the rotation of the rotating gear 4 will drive the side frame 3 to move. The movement of the side frame 3 will drive the drive rack 10 to move, thereby driving the third gear 33 to rotate. The rotation of the third gear 33 will drive the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 will drive the second bevel gear 32 to rotate, which will eventually drive the moving frame 91 to move. The drive rack 10 must first mesh with the third gear 33 in the direction of movement to pre-clean the bed rack 2 and ensure that wear is reduced when the rotating gear 4 meshes with the bed rack 2.

[0039] The working principle of this invention is as follows: the two side frames 3 are connected together by a crossbeam. A processing component can be mounted on the crossbeam, and this component can move laterally, rotate, vibrate, etc., enabling various processing of objects placed on the machine tool 1. The motor of the drive gear 8 is started, which drives the transmission gear 5 to rotate, thereby driving the belt 6 and the rotating gear 4 on the same side to rotate. Simultaneously, the rotation of the transmission gear 5 drives the spindle 7 to rotate, thereby driving the transmission gear 5, belt 6, and rotating gear 4 on the other side to rotate. The rotating gear 4 meshes with the bed rack 2, enabling the side frames 3 and the crossbeam to move back and forth along the machine tool 1, allowing adjustment of the processing position. Since the bed rack 2 is constantly exposed to the air, dust in the workshop will gradually accumulate on the bed. During the intervals between adjacent teeth of rack 2, the presence of dust during the rotation of rotating gear 4 increases wear, affecting the transmission accuracy and service life of rotating gear 4 and bed rack 2. Therefore, a drive rack 10 can be installed at the bottom of side frame 3. The drive rack 10 will first mesh with the third gear 33 in front, thereby driving the third gear 33 to rotate. The rotation of the third gear 33 drives the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 drives the second bevel gear 32 to rotate, thereby driving the first bevel gear 30 and the round rod 29 to rotate. The rotation of the round rod 29 drives the rotating plate 27 to rotate. The rotation of the rotating plate 27 will drive the movable frame 25 to move upward first. The upward movement of the movable frame 25 will drive the movable rod 23 and the movable plate 24 to move upward simultaneously. The upward movement of the movable rod 23 will drive the movable rod 23 to move upward. The sleeve 20 and the moving frame 91 move upwards. During this movement, the crossbar 17 and the second gear 21 move upwards and mesh with the second rack 22. The second gear 21 rotates within the notch 201, causing the crossbar 17 to rotate. The rotation of the crossbar 17 causes the first gear 18 to rotate. The rotation of the first gear 18 causes the upper and lower first racks 19 to move to both sides, thereby causing the vertical plates 13, rotating rods 14, horizontal plates 94, cams 15, and cleaning plates 92 to move synchronously. Initially, the limiting rod 16 is in contact with a section of the straight groove. During this process, the rotating rod 14 does not rotate. That is, the cleaning plate 92 moves to the outside of the moving frame 91 in this short time. Subsequently, the curved groove section of the limiting groove 141 opened by the rotating rod 14... The cleaning plate 92 is tilted by the cam 15 as it rotates around the limit rod 14, which in turn rotates the cam 15. Once the tilt angle of the cleaning plate 92 is determined, it will fit against the two sides of the intermittent. Since the two sides of the intermittent are tilted, forming an inverted trapezoidal shape, the cleaning plate 92 must be moved to both sides during the upward movement of the moving frame 91 to ensure that it remains in contact with the two sides of the intermittent. This ensures cleaning efficiency. During this process, the limit rod 16 is engaged with another straight section of the limit groove 141, and the rotating rod 14 will not rotate. Through the cooperation of the limit groove 141 and the limit rod 16, the tilt angle of the cleaning plate 92 can be adjusted as it moves towards the two sides of the intermittent, allowing for a tighter fit with the intermittent.It can perform intermittent dust removal. Continuous rotation of the rotating plate 27 will move the movable frame 25 to its highest position and then move it away from the bed rack 2. The lateral movement of the movable frame 25 will cause the movable rod 23 to move laterally along the movable plate 24, thereby moving the movable frame 91 to one side to avoid collision with the rotating gear 4.
