[0052] As Figures 1-3As shown, the integral high-precision double-end chamfering device also comprises a lateral adjusting mechanism 1 mounted on the plate edge sealing machine rack for adjusting the lateral position of the double-end chamfering assembly during operation. The lateral adjusting mechanism 1 comprises a mounting plate 11 fixed to the plate edge sealing machine rack. The rear side of the mounting plate 11 is provided with a lateral drive motor 12. The output end of the lateral drive motor 12 is connected with a main gear 13. A speed reducer is arranged between the lateral drive motor 12 and the main gear 13. The main gear 13 is horizontally connected with a driven gear 15 through a toothed belt 14. The center of the two sides of the driven gear 15 is fixed to the plate edge sealing machine rack through a connecting rod. The connecting rod is rotatably connected with the driven gear 15. During operation, when the plate strip is tracked and chamfered, the main gear 13 is driven to rotate by the lateral drive motor 12, and then the driven gear 15 is synchronously rotated by the toothed belt 14. Thus, the toothed belt 14 can be rotated by the main gear 13 and the driven gear 15. The vertical adjusting mechanism 2 and the double-end chamfering assembly are moved along with the plate by the fixed clamping plate 16 through the rotation of the toothed belt 14, so as to facilitate the tracking chamfering operation of the chamfering cutter 44.

The cylinder barrel of the tracking air cylinder 6 is fixed with a connecting seat 61. The extension end of the tracking air cylinder 6 is fixed to the side of the fixed clamping plate 16. The purpose of adding the tracking air cylinder 6 is to eliminate the tracking error of the double-end chamfering assembly during chamfering operation, and to ensure the stable pressure of the double-end chamfering assembly on the plate. During the tracking chamfering process of the front end of the plate strip, the tracking air cylinder 6 is beneficial to maintaining the pressure between the front end of the plate strip and the positioning ring, thereby improving the chamfering precision, and buffering the impact force of the plate on the double-end chamfering assembly at the moment of contact. When the tail end of the plate strip is tracked and chamfered, the contraction force of the tracking air cylinder 6 is beneficial to pressing the tail end of the plate strip by the positioning ring, thereby reducing the synchronization error of the tracking speed of the double-end chamfering assembly and the advancing speed of the plate, improving the chamfering precision. It should be noted that the tracking air cylinder 6 and the pressing air cylinder 32 are both conventional air cylinders.

[0054] As shown in Figure 3 and 4As shown, the transverse adjusting mechanism 1 further comprises two transverse sliding rails 17 fixed with the plate edge sealing machine frame, and a L-shaped fixed plate 19 is connected with the two transverse sliding rails 17 through common sliding connection, two transverse sliding seats 18 are installed on the front side of the L-shaped fixed plate 19 corresponding to the two transverse sliding rails 17, and the L-shaped fixed plate 19 slides on the transverse sliding rails 17 through the transverse sliding seats 18. When the transverse adjusting mechanism 1 works, the L-shaped fixed plate 19 will move on the two transverse sliding rails 17 through the fixed clamping plate 16 and the connecting seat 61, and the L-shaped fixed plate 19 will simultaneously drive the vertical adjusting mechanism 2 to move horizontally. Moreover, the lower end of the L-shaped fixed plate 19 is fixed with the upper end surface of the connecting seat 61 (as shown in Figure 6 By using the sliding positioning of the upper end of the L-shaped fixed plate 19 and the two transverse sliding rails 17, the connection stability of the fixed clamping plate 16 on the toothed belt 14 can be ensured, and the stability of the tracking cylinder 6 during use is also facilitated, so that the bearing force of the fixed clamping plate 16, the connecting seat 61 and the L-shaped fixed plate 19 on the toothed belt 14 is not too large, and the deformation of the toothed belt 14 is not too large, thereby affecting the vertical operation of the double-end chamfering assembly.

The vertical adjusting mechanism 2 comprises a vertical driving motor 21 installed on the lower end of the rear side of the L-shaped fixed plate 19 and a vertical positioning plate 24 on the rear side of the L-shaped fixed plate 19. A vertical sliding rail 25 is installed on the front surface of the vertical positioning plate 24, a vertical sliding seat 26 is installed on the rear side of the L-shaped fixed plate 19 corresponding to the vertical sliding rail 25, the vertical positioning plate 24 slides on the vertical sliding seat 26 through the vertical sliding rail 25, a vertical driving gear 22 is connected with the output end of the vertical driving motor 21, a rack plate 23 is vertically installed on one side of the vertical positioning plate 24, and the teeth on the surface of the rack plate 23 are engaged with the teeth on the surface of the vertical driving gear 22. During the operation of the double-end chamfering assembly, the vertical driving motor 21 is controlled to work in the forward direction, so as to drive the vertical driving gear 22 to rotate, and the vertical driving gear 22 drives the rack plate 23 to drive the vertical positioning plate 24 to rise. When the vertical positioning plate 24 rises, it vertically rises in the vertical sliding seat 26 through the vertical sliding rail 25. Thus, the double-end chamfering assembly can be driven to move upward through the L-shaped connecting plate 31, and vice versa, so as to realize the lifting adjustment of the double-end chamfering assembly.

[0056] As shown in Figure 8 and 9As shown, the vertical adjusting mechanism 2 further comprises an L-shaped connecting plate 31 installed on the rear side of the vertical positioning plate 24, and a U-shaped groove is formed between the L-shaped connecting plate 31 and the vertical positioning plate 24, and two limiting rods are symmetrically installed in the U-shaped groove between the L-shaped connecting plate 31 and the vertical positioning plate 24, and a transverse adjusting seat 33 is slidably connected to the two limiting rods; a pressing cylinder 32 is installed on the rear side of the L-shaped connecting plate 31, and the extension end of the pressing cylinder 32 extends through the L-shaped connecting plate 31 into the U-shaped groove and is fixed to the rear side of the transverse adjusting seat 33, and when the extension end of the pressing cylinder 32 is extended, it will push the transverse adjusting seat 33 to slide on the two limiting rods towards the vertical positioning plate 24, and the purpose of adding the pressing cylinder 32 is to push the L-shaped connecting plate 31 to approach the plate during operation by the extension of the pressing cylinder 32, and then the inner positioning ring 42 is pressed against the side of the plate, and since the inner positioning ring 42 of the double-end chamfer assembly has a bevel on the edge, it is convenient to extrude the inner positioning ring 42, thereby realizing the pressing and accurate positioning of the plate and the inner positioning ring 42, which is beneficial to improve the positioning accuracy and the chamfer accuracy and quality of the product.

[0057] As shown in Figure 10 and 11 The design of the integrated high-precision double-end chamfering device also comprises a tool bit adjusting assembly 3 connected to the vertical adjusting mechanism 2, which can adjust the size of the double-end chamfering assembly in the transverse and vertical directions before use, and the tool bit adjusting assembly 3 comprises a vertical positioning seat 7 fixed to the middle of the outer side of the transverse adjusting seat 33, the vertical positioning seat 7 is L-shaped, and a vertical adjusting screw 71 penetrates the top of the vertical positioning seat 7, the top end of the vertical adjusting screw 71 is provided with a knob, the bottom end of the vertical adjusting screw 71 is rotatably connected with a lifting plate 72, the side surface of the lifting plate 72 is slidably connected to the vertical positioning seat 7, and the vertical adjusting screw 71 is threadedly connected to the top of the vertical positioning seat 7, so that the position of the chamfering cutter 44 can be adjusted according to the size of the plate before use of the entire device, and the vertical direction can be adjusted by twisting the knob to drive the vertical adjusting screw 71 to rotate, and when the vertical adjusting screw 71 rotates, the lifting plate 72 will be lifted along the side surface of the vertical positioning seat 7 since it is threadedly connected to the top of the vertical positioning seat 7, and the chamfering motor 45 and the chamfering cutter 44 will be lifted by the lifting plate 72, which facilitates the adjustment of the position of the chamfering cutter 44 on the tool holder 4.

[0058] As shown in Figure 11As shown, the tool bit adjusting assembly 3 further comprises a mounting plate two 8 fixed on the other side of the lifting plate 72, and a positioning slide rod is symmetrically mounted on the rear side of the mounting plate two 8, and a guide seat 83 is slidably connected to the two positioning slide rods, a transverse adjusting screw 81 is connected through the middle part of the guide seat 83, one end of the transverse adjusting screw 81 is also provided with a knob, the transverse adjusting screw 81 is rotationally connected with the guide seat 83, one end of the transverse adjusting screw 81 penetrates through the mounting plate two 8 and is threadedly connected therewith, and a groove for the transverse adjusting screw 81 to extend is also formed in the side of the lifting plate 72 corresponding to the transverse adjusting screw 81; the bottom end of the guide seat 83 is fixedly connected with a motor slide rail 82, one end of the motor slide rail 82 is perpendicularly fixed with the guide seat 83, and the upper surface of the motor slide rail 82 is slidably connected with the lower surface of the lifting plate 72, and the bottom of the motor slide rail 82 is fixed with the chamfering motor 45;

[0059] When it is necessary to adjust the transverse position of the chamfering cutter 44, that is, to adjust the distance of the chamfering cutter 44 extending out of the tool shell 4, the knob on the transverse adjusting screw 81 can be twisted to screw into the mounting plate two 8 and extend into the groove, at this time, the transverse adjusting screw 81 will be close to the mounting plate two 8 synchronously with the guide seat 83, and since the guide seat 83 is slidably connected to the positioning slide rod, the stability of the guide seat 83 during movement can be ensured, when the guide seat 83 moves, the motor slide rail 82 will slide on the lower surface of the lifting plate 72, and the motor slide rail 82 drives the chamfering motor 45 and the chamfering cutter 44 to adjust the transverse position in the tool shell 4.

[0060] As Figure 1 As shown, the integrated high-precision double-end chamfering device also comprises a detection support 5 mounted on the frame of the plate edge sealing machine, and a detection probe 51 is mounted on the front side of one end of the detection support 5, and the detection probe 51 corresponds to the plate strip on the transmission roller of the plate edge sealing machine, and when the front end of the plate strip is transmitted to the position, the detection probe 51 can send a signal to the control system of the plate edge sealing machine, so that the double-end chamfering device is controlled to work to realize the tracking chamfering operation on the front end of the plate strip, and when the plate strip is transmitted and the detection probe 51 cannot detect the plate strip, the detection probe 51 will synchronously transmit a signal to the control system to make the control system control the double-end chamfering device to chamfer the rear end of the plate strip, and it should be noted that the detection probe 51 can be but is not limited to an infrared probe or other industrial detection probe.

[0061] The working principle of the utility model is as follows: in use, first, according to the size of the plate, the transverse position and vertical position of the chamfering cutter 44 in the tool shell 4 are adjusted by using the tool bit adjusting assembly 3, and after the adjustment is completed, the double-end chamfering device is started to work.

[0062] Firstly, before the plate reaches, the double-end chamfering assembly is below the plate, and the guide wheel 41 is below the block of the baffle 9, always in the horizontal or upward angle position; while the chamfering cutter 44 is always in the rotating state.

[0063] When the front end of the plate reaches, the detection probe 51 detects the plate, and the horizontal adjusting mechanism 1 and the vertical adjusting mechanism 2 start to work. At this time, the front end of the plate contacts the guide wheel 41, and the outer positioning ring 43 and the inner positioning ring 42 contact and press the upper surface and the side surface of the plate, and the horizontal adjusting mechanism 1 drives the double-end chamfering assembly to rise, so that the chamfering cutter 44 moves upward from the bottom. During the upward movement of the chamfering cutter 44, the oval guide wheel 41 is pressed by the front end surface of the plate and rotates gradually to the vertical state. The side surface and the front section of the plate are positioned by the side surface of the inner positioning ring 42 and the outer positioning ring 43, and the chamfering cutter 44 contacts the plate at a right angle to realize chamfering. At the same time, the double-end chamfering device tracks the plate in the horizontal forward direction to realize tracking chamfering.

[0064] When the chamfering cutter 44 moves above the plate, i.e. the front end chamfering of the plate is completed, the chamfering cutter 44 is separated from the plate, and the double-end chamfering device is driven by the horizontal adjusting mechanism 1 to move backward to the original position. The oval guide wheel 41 is rotated to the horizontal state by the plate.

[0065] When the tail end of the plate passes through the detection probe 51 and the detection probe 51 cannot detect the signal, according to the set distance difference, i.e. when the tail end of the plate to be chamfered is separated from the side surface of the oval guide wheel 41, the vertical adjusting mechanism 2 drives the chamfering cutter 44 to move downward from the top. During the downward movement of the chamfering cutter 44, the oval guide wheel 41 is pressed by the rear end surface of the plate and rotates gradually to the vertical state. The side surface and the rear section of the plate are positioned by the side surface of the inner positioning ring 42 and the outer positioning ring 43, and the chamfering cutter 44 contacts the plate at a right angle to realize chamfering. At the same time, the double-end chamfering device is driven by the horizontal adjusting mechanism 1 to track the plate in the horizontal forward direction to realize tracking chamfering of the tail end of the plate.

[0066] When the chamfering cutter 44 moves below the plate, i.e. the rear end chamfering of the plate is completed, the chamfering cutter 44 is separated from the plate, and the oval guide wheel 41 is in the vertical state. The double-end chamfering device is driven by the horizontal adjusting mechanism 1 to move backward to the original position, and then is driven by the vertical adjusting mechanism 2 to move downward to the original position. After the reset, the lower end of the oval guide wheel 41 is blocked by the baffle 9, and the oval guide wheel 41 is rotated to the horizontal or upward angle state.

[0067] Therefore, the chamfering operation of the front end and the rear end of the strip can be completed, and it should be noted that the contact of the head or tail of the plate with the chamfering cutter 44 is accompanied by the rotation of the oval guide wheel 41, and the feeding process of the chamfering cutter 44 is gradual, and the gradual feeding of the same position is beneficial to the stability and smoothness of the chamfering, and the contact between the head or tail of the plate and the positioning ring during the movement is flexible, which is beneficial to reduce the shaking and improve the chamfering quality.
