Description

Technical Field

[0001] This application relates to the field of machining center technology, and in particular to an intelligent self-cleaning machining center. Background Technology

[0002] In the field of modern machining, machining centers, as a highly automated multi-functional machine tool, are widely used in various industries. During the machining process, machining centers inevitably generate a large amount of metal scrap, chips, and impurities such as coolant. If these impurities are not cleaned in time, they will affect the machining accuracy of the machining center.

[0003] A common type of vertical machining center includes a worktable with several parallel slots on its upper surface along the horizontal direction. When cleaning the worktable, air blowing equipment is usually used to blow away the debris on the surface of the worktable, but a large amount of debris will still remain in the slots of the machining platform. At this time, the staff needs to clean each slot in turn, which is time-consuming, labor-intensive, and increases the workload. Utility Model Content

[0004] To facilitate the cleaning of all slots on the workbench, save manpower, and reduce the labor intensity of workers, this application provides an intelligent self-cleaning machining center.

[0005] The intelligent self-cleaning machining center provided in this application adopts the following technical solution:

[0006] An intelligent self-cleaning machining center includes a base and a worktable. The worktable is located on top of the base. The upper surface of the worktable has several parallel slots along a horizontal direction. A guide rail parallel to the slots is fixedly installed on the side wall of the worktable. A sliding block is slidably installed within the guide rail. A sliding assembly for driving the sliding block is provided in the guide rail. An upwardly extending bracket is connected to the sliding block. A connecting shaft perpendicular to the slots in a horizontal direction is provided on the bracket. The connecting shaft is located above the worktable. Several brush rollers are fixedly installed on the connecting shaft. Each brush roller corresponds to one slot. Brush bristles are provided on the peripheral wall of each brush roller, extending into the slot and contacting the inner wall of the slot.

[0007] By adopting the above technical solution, the sliding component can drive the sliding block to slide within the guide rail, thereby moving the bracket, connecting shaft, and brush roller along the direction of the groove. During the movement of the brush roller, the bristles clean the inner wall of the groove, collecting the residual waste in the groove towards one end and finally pushing it out of the groove. Compared with the traditional manual cleaning method, it eliminates the need for staff to manually clean each groove sequentially, saving manpower and reducing the labor intensity of workers.

[0008] Preferably, the connecting shaft is rotatably connected to the bracket, and the bracket is provided with a rotating component for driving the rotating shaft to rotate.

[0009] By adopting the above technical solution, the rotating component can drive the connecting shaft to rotate, thereby driving all the brush rollers to rotate. When the brush rollers rotate while moving along the groove to clean, the rotating bristles can generate a stronger scraping and sweeping force for stubborn debris attached to the inner wall of the groove. Compared with brush rollers that only move in a straight line, it can more effectively peel the debris off the inner wall of the groove, further improving the cleaning effect of debris in the groove.

[0010] Preferably, the rotating assembly includes a rack, a reversing gear, and a drive gear. The rack is fixed to the top of the guide rail and is parallel to the guide rail, with the teeth of the rack facing upwards. The drive gear is coaxially fixed to the connecting shaft. The reversing gear rotates on the side wall of the bracket and is located between the drive gear and the rack. The bottom of the reversing gear meshes with the rack, and the top of the reversing gear meshes with the drive gear.

[0011] By adopting the above technical solution, when the sliding component drives the sliding block to slide within the guide rail, the bracket moves accordingly. During the movement of the bracket, the reversing gear rolls along the rack, and the rolling of the reversing gear drives the drive gear to rotate, ultimately driving the brush roller to rotate. In addition, the reversing gear can reverse the rotation direction of the drive gear, ensuring that the rotation direction of the brush roller and the movement direction of the sliding block are coordinated. For example, when the sliding block moves to the left, the waste is concentrated on the left side of the brush roller. The motion transmitted by the reversing gear causes the drive gear to rotate clockwise, thereby causing the brush bristles of the brush roller to peel off the waste and push the waste to the left side of the brush roller (i.e., the final discharge direction of the waste), which is more conducive to the discharge of waste.

[0012] Preferably, the sliding assembly includes a lead screw, which is parallel to the guide rail, rotates within the guide rail, and is threadedly engaged with the sliding block.

[0013] By adopting the above technical solution, when the lead screw rotates, due to the threaded engagement between the lead screw and the sliding block, according to the lead screw transmission principle, the rotational motion of the lead screw can be converted into the linear motion of the sliding block within the guide rail, and the lead screw transmission has high stability.

[0014] Preferably, the sliding assembly further includes a motor, which is fixedly connected to the guide rail, and the drive shaft of the motor is coaxially fixed with the lead screw.

[0015] By adopting the above technical solution, the motor provides stable and controllable power for the rotation of the lead screw. After the motor starts, the motor drive shaft drives the lead screw to rotate, which in turn drives the sliding block engaged with the thread on the lead screw to move linearly in the guide rail, realizing the movement of the brush roller along the groove direction. The motor enables the entire self-cleaning process to be automatically controlled. The intelligence level of the equipment can be improved by controlling the motor's opening, closing, speed and direction.

[0016] Preferably, a hinge shaft is fixedly provided on the side wall of the sliding block, the bottom of the bracket is rotatably connected to the hinge shaft, and a locking component is provided between the sliding block and the bracket to fix the sliding block and the bracket.

[0017] By adopting the above technical solution, when cleaning the workbench, the sliding block and the bracket are fixed by the locking component to ensure the stability between the sliding frame and the bracket, thereby ensuring the stability of the brush roller; after the workbench is cleaned, the sliding block moves to one end of the slide rail. At this time, the connection between the sliding frame and the bracket is released by the locking component, so that the bracket can rotate and the connecting shaft and the brush roller on the connecting shaft are moved away from the top of the workbench, so as not to obstruct the operation on the workbench.

[0018] Preferably, the locking component includes a pin that penetrates the side wall of the bracket and is slidably connected to the bracket. The side wall of the sliding block has a pin hole, and the pin extends into the pin hole and abuts against the side wall of the pin hole.

[0019] By adopting the above technical solution, when it is necessary to fix the sliding block and the bracket, the pin is inserted into the pin hole on the side wall of the sliding block. The pin abuts against the side wall of the pin hole, fixing the bracket and the sliding block together and preventing the bracket from rotating arbitrarily around the hinge axis.

[0020] Preferably, the locking assembly further includes a tension spring and a pull head. The pull head is fixed to the end of the pin away from the pin hole. The tension spring is located between the pull head and the bracket. One end of the tension spring is fixedly connected to the pull head, and the other end of the tension spring is fixedly connected to the bracket. The tension spring drives the pull head to move closer to the bracket.

[0021] By adopting the above technical solution, the tension spring applies a pulling force towards the bracket to the pull head, ensuring that the pin is always subjected to a force towards the pin hole after insertion. This ensures that the pin remains stably within the pin hole, and even if vibration occurs during cleaning, the pin is less likely to come out of the pin hole due to vibration, thus improving the reliability and stability of the locking component. When it is necessary to remove the pin, the operator only needs to pull the pull head to overcome the tension spring force, which will allow the pin to be pulled out of the pin hole and disengage from the socket.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting guide rails, sliding blocks, sliding components, brackets, connecting shafts, and brush rollers, the sliding components drive the sliding blocks to move along the opening direction of the groove. The brush rollers move with the sliding blocks, and the bristles of the brush rollers penetrate deep into the groove to clean up residual waste. The waste is then pushed out to one end of the groove, saving manpower and reducing the labor intensity of workers.

[0024] 2. By setting up a rack, reversing gear, drive gear, lead screw, and motor, the motor drives the lead screw to rotate, which in turn moves the sliding block along the guide rail. At the same time, the rack, reversing gear, and drive gear cooperate with each other to make the brush roller move and rotate at the same time, thereby enhancing the cleaning effect on waste.

[0025] 3. By setting up a hinge shaft, pin, pin hole, tension spring, and pull head, when cleaning the worktable, the pin is inserted into the pin hole, and the tension spring is used to fix the bracket and sliding block to prevent the brush roller from shaking. After the worktable is cleaned, the pull head is pulled to remove the pin, so that the bracket can be deflected and the brush roller and connecting shaft are moved away from the top of the worktable.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses an intelligent self-cleaning machining center. (Refer to...) Figure 1It includes a base 1 and a worktable 2. The worktable 2 is located on top of the base 1. The upper surface of the worktable 2 has several parallel slots 21 opened in the horizontal direction. A guide rail 22 parallel to the slots 21 is fixedly installed on the side wall of the worktable 2. A sliding block 221 is slidably installed in the guide rail 22. A sliding component 3 for driving the sliding block 221 to slide is provided in the guide rail 22.

[0032] Reference Figure 1 and Figure 2 A bracket 4 extending upward is connected to the sliding block 221. Specifically, a hinge shaft 2211 is fixedly installed on the side wall of the sliding block 221, and the bottom of the bracket 4 is rotatably connected to the hinge shaft 2211.

[0033] Reference Figure 2 and Figure 3 A locking component 6 is provided between the sliding block 221 and the bracket 4 to fix the sliding block 221 and the bracket 4. Specifically, the locking component 6 includes a pin 61, a tension spring 63, and a pull head 64. The pin 61 passes through the side wall of the bracket 4 and is slidably connected to the bracket 4. In this application, a limiting block is integrally formed on the side wall of the pin 61, and a limiting groove is formed in the bracket 4. The limiting block slides in the limiting groove, and both ends of the pin 61 pass through the side wall of the bracket 4 and extend out of the limiting groove.

[0034] Reference Figure 2 and Figure 3 A pin hole 62 is provided on the side wall of the sliding block 221. One end of the pin 61 extends into the pin hole 62 and abuts against the side wall of the pin hole 62. In addition, a constraint hole 65 is also provided on the side wall of the sliding block 221. The pin 61 can also extend into the constraint hole 65. The constraint hole 65 and the pin hole 62 are 180 degrees apart in the circumferential direction of the hinge shaft 2211. When the pin 61 is inserted into the constraint hole 65, the bracket 4 extends downward from the sliding block 221.

[0035] Reference Figure 2The support 4 is equipped with a connecting shaft 41 perpendicular to the slot 21 in the horizontal direction. The connecting shaft 41 is located above the worktable 2. Several brush rollers 411 are fixedly mounted on the connecting shaft 41, each corresponding to a slot 21. The peripheral wall of the brush roller 411 is provided with bristles that extend into the slot 21 and contact the inner wall of the slot 21. The connecting shaft 41 is rotatably connected to the support 4. The support 4 is equipped with a rotating assembly 5 for driving the rotating shaft to rotate. Specifically, the rotating assembly 5 includes a rack 51, a reversing gear 52, and a drive gear 53. The rack 51 is fixed to the top of the guide rail 22 and is parallel to the guide rail 22, with the teeth of the rack 51 facing upwards. The drive gear 53 is coaxially fixed to the connecting shaft 41. The reversing gear 52 rotates on the side wall of the support 4 and is located between the drive gear 53 and the rack 51. The bottom of the reversing gear 52 meshes with the rack 51, and the top of the reversing gear 52 meshes with the drive gear 53. In this application, as the sliding block slides to the end of the guide rail, the reversing gear can disengage from the rack.

[0036] To achieve automatic movement of the brush roller 411 along the groove 21, refer to Figure 1 The sliding assembly 3 includes a lead screw 31 and a motor 32. The lead screw 31 is parallel to the guide rail 22 and rotates within the guide rail 22. The lead screw 31 is threadedly engaged with the sliding block 221. The motor 32 is fixedly connected to the guide rail 22, and the drive shaft of the motor 32 is coaxially fixed with the lead screw 31. The motor 32 is a servo motor and is electrically connected to the controller of the machining center.

[0037] The implementation principle of an intelligent self-cleaning machining center according to an embodiment of this application is as follows: When it is necessary to clean the slot 21 of the workbench 2, the pin 61 is first inserted into the pin hole 62. Under the action of the tension spring 63, the pin 61 is stably held in the pin hole 62, so that the bracket 4 and the sliding block 221 are relatively fixed. At this time, the brush roller 411 on the connecting shaft 41 is located above the workbench 2. Then the motor 32 is started. The motor 32 drives the lead screw 31 to rotate. The lead screw 31 drives the sliding block 221 to slide in the guide rail 22. The sliding block 221 drives the bracket 4, the connecting shaft 41 and the brush roller 411 to move along the slot 21. During the movement of the bracket 4, the reversing gear 52 rolls along the rack 51. The rolling of the reversing gear 52 drives the drive gear 53 to rotate. The drive gear 53 drives the connecting shaft 41 to rotate, thereby causing the brush roller 411 to rotate while moving along the slot 21. The bristles on the rotating brush roller 411 clean the inner wall of the slot 21, collecting the remaining debris along the slot 21 to one end and finally pushing it out of the slot 21. After the cleaning is completed, the sliding block 221 is located at the end of the guide rail 22. Pulling the pull head 64 overcomes the tension of the tension spring 63 and pulls the pin 61 out of the pin hole 62. At this time, the bracket 4 can rotate around the hinge shaft 2211, moving the connecting shaft 41 and the brush roller 411 away from the worktable 2, and inserting the pin 61 into the constraint hole 65. The connecting shaft 41 and the brush roller 411 do not hinder subsequent processing operations on the worktable 2.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
