DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] Example 1, reference Figure 1~Figure 3 , which is the first embodiment of the present invention, provides a chip suction device for a tubular workpiece cutting device, which can absorb the waste chips generated during the cutting of the tubular workpiece, thereby preventing the waste chips from splashing and affecting the efficiency and safety of the cutting operation, and includes a chip suction mechanism 100.

[0026] Specifically, the chip suction mechanism 100 includes a mounting plate 101, on the outer surface of which a first magnet 102 is mounted. The mounting plate 101 can be adsorbed on the outer side of the cutting device by the magnetic force of the first magnet 102, and its position can be adjusted at will to achieve better adaptability between the chip suction device and the cutting device. A back plate 103 is connected to the other side surface of the mounting plate 101, and there is a certain space gap between the mounting plate 101 and the back plate 103. At the same time, a main adjusting member 104 and a sub-adjusting member 105 are sequentially mounted at the same height on the inner side surface of the back plate 103, and a chip suction member 106 is connected to the outer sides of the main adjusting member 104 and the sub-adjusting member 105. At the same time, an isolation net 107 for isolating waste chips is also installed at the outer opening of the chip suction member 106.

[0027] Furthermore, the main adjusting member 104 includes a first retaining ring 104a rotatably embedded in the back plate 103, and the end face of the first retaining ring 104a is coaxially connected with a main connecting tooth piece 104b, and a positioning hole 104c is left at the center of the surface of the main connecting tooth piece 104b on the same side as the first retaining ring 104a, and the positioning hole 104c is arranged in a ring array with respect to the main connecting tooth piece 104b, and at the same time, an elastic piece 103a matching the positioning hole 104c is symmetrically arranged in the groove on the inner side of the back plate 103.

[0028] The auxiliary adjusting member 105 includes a second retaining ring 105a rotatably embedded in the back plate 103, and the end face of the second retaining ring 105a is coaxially connected with a secondary connecting tooth piece 105b. The main connecting tooth piece 104b and the secondary connecting tooth piece 105b can be freely rotated while ensuring the connection with the back plate 103 through the first retaining ring 104a and the second retaining ring 105a respectively. At the same time, the main connecting tooth piece 104b and the secondary connecting tooth piece 105b are meshed, so that when any connecting tooth piece rotates, it can drive the other connecting tooth piece to rotate in the opposite direction, thereby achieving the purpose of synchronously adjusting the angle between the two chip suction members 106, so as to improve the chip suction effect on tubular workpieces of different sizes.

[0029] The chip suction member 106 includes a chip suction box 106a which is opened toward one side of the mounting plate 101, and the chip suction box 106a is arranged in an arc shape so that it can better adapt to the outside of the tubular workpiece, and a plurality of second magnets 106b are arranged in an array along the extension direction on the inner bottom surface of the chip suction box 106a, and the second magnets 106b can absorb the metal debris splashed during the cutting process through their own magnetic force.

[0030] Among them, the elastic sheet 103a is made of deformable material, so that the connection state between the positioning port 104c and the elastic sheet 103a can be adjusted by the deformation of the elastic sheet 103a itself, that is, when the elastic sheet 103a bounces up, the elastic sheet 103a and the positioning port 104c are engaged, so as to realize the positioning of the main connecting tooth sheet 104b, and then under the meshing cooperation of the main connecting tooth sheet 104b and the auxiliary connecting tooth sheet 105b, when the main connecting tooth sheet 104b is locked, the auxiliary connecting tooth sheet 105b can be locked, thereby completing the angle adjustment and locking of the chip suction parts 106 on both sides, which is convenient for the chip suction equipment to be used with tubular workpieces of different sizes.

[0031] When in use, the elastic sheet 103a is pressed toward the groove in the back plate 103 to release the engagement between the elastic sheet 103a and the positioning hole 104c on the main connecting tooth sheet 104b. At this time, the user can rotate the main connecting tooth sheet 104b and adjust the chip suction pieces 106 on both sides through the engagement between the main connecting tooth sheet 104b and the auxiliary connecting tooth sheet 105b. The angle between the two chip suction pieces 106 is adjusted to match the size of the tubular workpiece. Subsequently, the chip suction device is adsorbed on the cutting device through the first magnet 102, and the chip suction device is arranged above the tubular workpiece. Before suctioning the chips, chip suction devices need to be respectively arranged on both sides of the cutting device, so that the chips can be adsorbed and collected during the cutting process. During cutting, the second magnet 106b in the chip suction box 106a adsorbs the chips to the isolation net 107 through magnetic force, thereby realizing the collection of the chips, and the chips on the isolation net 107 can be cleaned after the cutting is completed.

[0032] In summary, through the cooperation between the main adjusting member 104 and the auxiliary adjusting member 105, a single rotation of the main adjusting member 104 can realize the synchronous adjustment of the chip suction members 106 on both sides, which can meet the chip suction needs of workpieces of different sizes. Under the setting of the elastic sheet 103a, the main adjusting member 104 and the auxiliary adjusting member 105 are limited to ensure the stability of the chip suction equipment during use.

[0033] Example 2, reference Figure 1~Figure 4 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a chip suction device 100 for a tubular workpiece cutting device, which solves the problem that the chips on the isolation net 107 are inconvenient to clean due to the magnetic force of the second magnet 106b. It includes a main opening and closing member 108, an auxiliary opening and closing member 109 and a covering member 110.

[0034] Specifically, the chip suction mechanism 100 also includes a main opening and closing member 108 and a secondary opening and closing member 109 which are sequentially arranged on the inner surface of the mounting plate 101, and a covering member 110 located on the outside of the main opening and closing member 108, and covering members 110 are installed inside the chip suction members 106 on both sides, and the two covering members 110 cooperate with the main opening and closing member 108 and the secondary opening and closing member 109 respectively.

[0035] Furthermore, the main opening and closing member 108 includes a main opening and closing snap ring 108a movably embedded in the interior of the mounting plate 101 , and the end surface of the main opening and closing snap ring 108a is coaxially connected with the driving tooth 108b.

[0036] The auxiliary opening and closing member 109 includes an auxiliary opening and closing snap ring 109 a rotatably embedded in the mounting plate 101 , and the end surface of the auxiliary opening and closing snap ring 109 a is coaxially connected with a driven tooth 109 b .

[0037] The cover 110 includes a lining plate 110a disposed inside the dust suction box 106a, a plurality of holes 110b are sequentially disposed on the lining plate 110a, and a plurality of opening and closing plates 110c are sequentially hingedly disposed on the outer surface of the hole 110b, the opening and closing plates 110c are matched with the hole 110b, and a driving tooth 110d is coaxially disposed above the opening and closing plates 110c along the hinge point. It should be noted that the position of the opening and closing plates 110c corresponds to the second magnet 106b, and the opening and closing plates 110c are made of a material with a high magnetic susceptibility. When the opening and closing plates 110c are aligned with the second magnet 106b, the second magnet 106b is rotated. b is used for covering, the magnetic force of the second magnet 106b acts on the opening and closing plate 110c, and it is difficult to affect the isolation net 107 and the waste chips in the outside world. When the opening and closing plate 110c is opened, the magnetic force of the second magnet 106b can pass through the opening on the lining plate 110a to exert magnetic force on the outside world. At the same time, the outer sides of the multiple driving teeth 110d are simultaneously matched with a rack 110e, and a traction rod 110f is arranged at the end of the rack 110e. One end of the traction rod 110f of the two sets of covering members 110 is respectively hinged with the active tooth 108b and the driven tooth 109b.

[0038] Furthermore, the active teeth 108b and the driven teeth 109b are meshed together, so that when the active teeth 108b rotate, the meshing transmission between them and the driven teeth 109b can realize synchronous rotation of the active teeth 108b and the driven teeth 109b, thereby realizing synchronous control of the internal covering parts 110 of the dust suction boxes 106a on both sides.

[0039] Preferably, the rack 110e is arranged in an arc shape along the bending direction of the dust suction box 106a, and the plurality of driving teeth 110d connected to the outer side of the rack 110e are meshed along the rack, and at the same time, the two ends of the connecting rod 202c110f are respectively hinged to the rack 110e and the active tooth 108b, so that when the active tooth 108b rotates, the rack 110e can move under the transmission of the connecting rod 202c110f, and through the cooperation with the driving tooth 110d, the opening and closing plate 1 10c rotates to achieve the shielding or offset of the opening and closing plate 110c relative to the second magnet 106b. When the opening and closing plate 110c blocks the second magnet 106b, the magnetic force of the second magnet 106b can be isolated. At this time, the debris on the isolation net 107 is not affected by the magnetic force and can fall off smoothly for the user to clean. When the opening and closing plate 110c is offset relative to the second magnet 106b, the magnetic force of the second magnet 106b passes through the lining plate 110a to adsorb the debris, thereby collecting the debris.

[0040] When in use, by rotating the active tooth 108b, the driven tooth 109b rotates synchronously in the opposite direction, and the rack 110e is pulled by the traction rod 110f. While the racks 110e on both sides move, the rotation of the opening and closing plates 110c in the corresponding chip suction box 106a is controlled by means of the driving teeth 110d, so as to control the release and blocking of the magnetic force of the second magnet 106b. When the opening and closing plate 110c blocks the second magnet 106b, the magnetic force of the second magnetic force is difficult to release due to the combination of the opening and closing plate 110c and the lining plate 110a, so that the waste chips adsorbed on the isolation net 107 can fall freely without being affected by the magnetic force, which is convenient for users to clean and transfer the waste chips. When the opening and closing plate 110c is opened, the magnetic force of the second magnet 106b is released, and the waste chips can be adsorbed on the isolation net 107 by the magnetic force during the cutting process.

[0041] In summary, through the linkage cooperation between the main opening and closing member 108, the auxiliary opening and closing member 109 and the covering member 110, when the main opening and closing member 108 rotates, the covering member 110 can control the release and covering of the magnetic force of the second magnet 106b, thereby realizing the switching of the working state of the chip suction device between waste cleaning and waste adsorption.

[0042] Example 3, reference Figure 1 to Figure 6 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a regulating mechanism 200 for the chip suction device of the tubular workpiece cutting device, which solves the problem of inconvenience in controlling the use of the main adjusting member 104 and the main opening and closing member 108, and includes a control member 201, a linkage member 202 and a conversion member 203.

[0043] Specifically, the control component 201 includes a control rod 201a that passes through the back plate 103. The outer sleeve of the control rod 201a is provided with a pressure plate 201b, and the pressure plate 201b is arranged on the outside of the elastic sheet 103a. When the pressure plate 201b moves toward the direction of the elastic sheet 103a, the elastic sheet 103a can be squeezed to make the elastic sheet 103a deform and disengage from the positioning hole 104c on the surface of the main connecting tooth sheet 104b. That is, the main connecting tooth sheet 104b can be unlocked by moving the control rod 201a. At the same time, the end of the control rod 201a is coaxially connected with the rotating column 201c.

[0044] A first connecting sleeve 104d is provided on the other side surface of the main connecting tooth piece 104b, and two first limiting rings 104e are sequentially provided on the inner wall of the first connecting sleeve 104d. At the same time, a second connecting sleeve 108c is coaxially connected to the outer side surface of the active tooth 108b, and two second limiting rings 108d are sequentially provided inside the second connecting sleeve 108c. Linkage parts 202 and conversion parts 203 are both provided inside the first connecting sleeve 104d and the second connecting sleeve 108c. The two groups of linkage parts 202 and the conversion parts 203 are arranged in reverse, and the two groups of linkage parts 202 and the conversion parts 203 are respectively arranged between the two first limiting rings 104e and the second limiting rings 108d, so that the main adjusting part 104 and the main opening and closing part 108 are respectively controlled by the two groups of linkage parts 202 and the conversion parts 203 arranged up and down.

[0045] The linkage member 202 includes a rotating cylinder 202a, and two notches 202b are provided in a ring array on the outer side of the rotating cylinder 202a. Connecting rods 202c110f are provided inside the two notches 202b, and a stop block 202d is movably sleeved on the outer side of the connecting rods 202c110f.

[0046] The conversion member 203 includes a sleeve 203a rotatably disposed inside the rotating drum 202a. A compensation groove 203b is disposed on the inner wall of the sleeve 203a, and the end of the compensation groove 203b is connected to the approach groove 203c.

[0047] Preferably, the rotating column 201c is arranged in a prismatic shape, and the top opening of the rotating cylinder 202a cooperates with the rotating column 201c, so that when the rotating column 201c rotates with the control rod 201a, the rotating cylinder 202a and the control rod 201a can rotate synchronously, and two insertion heads 201d are sequentially arranged on the outside of the rotating column 201c, and the two insertion heads 201d can respectively cooperate with the compensation groove 203b and the approach groove 203c on the inner walls of the two sleeves 203a.

[0048] It is worth noting that the inner edge of the sleeve 203a is circular and its opening size is larger than the rotating column 201c. Therefore, when the rotating column 201c moves along its axial direction, the smooth rotation of the sleeve 203a can be guaranteed. At the same time, through the cooperation between the insertion head 201d and the compensation groove 203b, the synchronous rotation of the sleeve 203a and the rotating cylinder 202a when the control rod 201a rotates can be guaranteed, so as to achieve the stability of the relative state between the sleeve 203a and the block 202d.

[0049] The compensation groove 203b is arranged in a vertical groove shape, and the approach groove 203c is arranged in a spiral shape along the inner wall of the sleeve 203a. Initially, the insertion head 201d located inside the first connecting sleeve 104d is located in the middle section of the corresponding compensation groove 203b, and the insertion head 201d located in the second connecting sleeve 108c is located at the connection between the corresponding compensation groove 203b and the approach groove 203c, so that when the control rod 201a moves outward along the back plate 103, the insertion head 201d located inside the first connecting sleeve 104d is located in the middle section of the corresponding compensation groove 203b, and the insertion head 201d located inside the second connecting sleeve 108c is located at the connection between the corresponding compensation groove 203b and the approach groove 203c. The insertion head 201d inside the sleeve 104d can move with the control rod 201a to the connection between the compensation groove 203b and the approach groove 203c, and the displacement of the pressure plate 201b is compensated by the vertical distance of the movement of the insertion head 201d, so as to first release the rotation restriction of the elastic sheet 103a on the main connecting tooth piece 104b, and as the control rod 201a continues to move outward, the insertion head 201d cooperates with the approach groove 203c, and through the approach groove 203c, the pressure plate 201b is moved. c is spirally arranged, during the rising process of the insertion head 201d, the sleeve 203a is pushed to rotate by means of the approach groove 203c, and the outer edge of the sleeve 203a is arranged in an elliptical shape, so that when the sleeve 203a rotates, the relative position between the stop block 202d and the sleeve 203a changes, and the stop block 202d is pushed out by the outer wall of the sleeve 203a, so that the stop block 202d is tightly attached to the inner wall of the first connecting sleeve 104d, and the stop block 202d is made of rubber material, thereby, with the help of the friction force between the stop block 202d and the first connecting sleeve 104d, the first connecting sleeve 104d is driven to rotate synchronously while the control rod 201a rotates, so as to realize the rotation control of the main adjusting member 104, and when the control rod 201a moves outward, the insertion head 201d in the second connecting sleeve 108c moves along the compensation groove 203b at this time, ensuring that the linkage member 202 in the second connecting sleeve 108c is not affected; When the control rod 201a moves inward along the direction of the mounting plate 101, the insertion head 201d located in the second connecting sleeve 108c moves into the approach groove 203c. Then, with the cooperation of the approach groove 203c, the sleeve 203a located in the second connecting sleeve 108c can be pushed to rotate, thereby realizing the locking of the linkage member 202 and the second connecting sleeve 108c, and achieving the purpose of controlling the rotation of the main opening and closing member 108.

[0050] When in use, the connection switching between the linkage part 202 and the first connecting sleeve 104d and the second connecting sleeve 108c is achieved by pushing and pulling the control rod 201a inward and outward. Therefore, under the rotation of the control rod 201a, the operation of the main adjustment part 104 and the main opening and closing part 108 can be controlled respectively, thereby realizing the decentralized control of the opening size adjustment and the adsorption state conversion of the chip suction equipment.

[0051] In summary, through the linkage cooperation between the control part 201, the linkage part 202 and the conversion part 203, the opening size of the chip suction box 106a and the adsorption state conversion of the chip suction box 106a can be controlled by only pulling and rotating the control rod 201a, making the use of the chip suction equipment more convenient and efficient, and at the same time improving the adaptability between the chip suction equipment and tubular workpieces of different sizes.
