Description

Technical Field

[0002] Cutting is the process of using a tool to remove excess material from the workpiece to obtain parts that meet the requirements in terms of shape, dimensional accuracy and surface quality.

[0003] In this regard, China applied for patent number: CN202211246237.9, which discloses a CNC machine tool with a chip guiding structure, including a base frame, a frame, a working machine tool, a bracket, a light-transmitting plate and a control panel, etc. A frame is fixed on the top of the base frame, and a working machine tool capable of cutting plates is installed on one side of the frame. A bracket for placing plates is symmetrically slidably provided in the frame, and a light-transmitting plate is rotatably provided on the frame. A control panel is provided on the frame at the lower side of the light-transmitting plate, and the working machine tool is electrically connected to the control panel. The scraper is used to scrape and clean the debris on the rotating plate, and the cleaning effect is more obvious. The debris is not easy to fall to other places. At the same time, the guide groove can be cleaned to avoid clogging by residual debris.

[0004] The CNC machine tool is provided with a rotatable rotating plate and a scraping mechanism to guide the debris for unified collection. However, in actual use, some larger debris will fall on the rotating plate and get stuck in the groove on the surface. When the scraping mechanism is used to clean the debris on the rotating plate, since part of the debris is located in the groove, the movement of the scraping mechanism cannot press the debris into the groove, and the debris cannot be taken out of the groove, so that the debris will be stuck between the scraping mechanism and the rotating plate. As the scraping mechanism moves, the debris will scratch the rotating plate, making the use effect of the device unsatisfactory and affecting the user experience of the device.

[0005] Therefore, in order to solve the above problems, a fastener cutting device with a chip cleaning function is proposed. Summary of the invention

As the scraping mechanism moves, the debris will scratch the rotating plate, making the use effect of the device unsatisfactory and affecting the use experience of the device.

[0010] Preferably, a material guiding structure is installed inside the box body, and the material guiding structure includes a material trough, the material trough is movably installed on the inner side of the movable trough, the bottom surface of the material trough is fixedly connected with a fixing column, the right side wall of the material trough is fixedly connected with a fixing plate, the side wall of the fixing plate is integrally formed with a convex strip, a rotating shaft is movably installed on the right side wall of the box body through a bearing, a second sprocket is welded to the middle part of the rotating shaft, a chain is sleeved on the outer side of the second sprocket, discs are welded to the left and right ends of the rotating shaft, and a convex ball is integrally formed on the surface of the disc.

[0011] Preferably, two groups of movable plates are provided, and the two groups of movable plates are installed front and back, the surface of the guide block is in contact with the inner wall of the box body, and one end of the coil spring is fixedly connected to the inner wall of the worm gear cylinder.

[0012] Preferably, the worm gear cylinder is movably mounted inside the housing via a bearing, the worm is meshed with the worm gear cylinder, and the output end of the motor is fixedly connected to the worm.

[0013] Preferably, the end of the block is exposed from the inner wall of the box, the top surface of the block fits with the bottom surface of the guide block, the slot and the inclined groove cooperate with the arc-shaped insertion rod, and one end of the spring is fixedly connected to the inner wall of the box.

[0014] Preferably, the material trough is in a state of being lower on the left and higher on the right, the fixed column is movably installed in the inner wall of the movable trough through a bearing, and the fixed plate is exposed from the right side wall of the box body through the movable trough.

[0015] Preferably, the upper end of the chain is sleeved on the outer side of the first sprocket, the convex balls and the convex strips cooperate with each other, and the two groups of convex balls are arranged at 90 degrees.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the movable plate arranged on the cutting equipment of the present invention can be deflected downward, and the cutting chips can be poured into the material trough. In combination with the limiting structure, the cutting chips on the surface can be separated from the movable plate under the action of inertia during the deflection process, and fall onto the movable plate under the action of gravity, which can enhance the movement effect of the cutting chips on the movable plate, reduce the accumulation of cutting chips on the movable plate, and improve the cleaning effect of the cutting chips.

[0017] A rotating structure, a limiting structure and a material guiding structure are provided. The motor is started to drive the worm to rotate. The worm is meshed with the worm gear cylinder. When the worm rotates, the worm gear cylinder is driven to rotate. When the worm gear cylinder rotates, the movable plate is driven to deflect through the coil spring, and the guide block on the movable plate is stuck on the top surface of the clamping block. The guide block is limited by the clamping block, so the movable plate cannot be deflected immediately. Then, when the worm gear cylinder is driven by the worm, it will rotate relative to the movable plate on the outside and drive the coil spring to undergo elastic deformation.

[0018] When the worm gear cylinder rotates, it will drive the guide rail to rotate, and the arc-shaped plug rod is slidably connected to the guide rail. Therefore, when the worm gear cylinder drives the guide rail to rotate, the arc-shaped plug rod will slide on the guide rail in the opposite direction of rotation. When the arc-shaped plug rod moves to one end of the guide rail, the rotation of the worm gear cylinder can drive the arc-shaped plug rod to deflect through the guide rail, and the end of the arc-shaped plug rod is inserted into the slot. As the worm gear cylinder continues to rotate, it will drive the arc-shaped plug rod to push the inclined slot, so that the card block is retracted into the inner wall of the box body and squeezes the spring, and the card block is moved away from the bottom surface of the guide block, so that the card block releases the limit on the guide block, so the movable plate and the guide block are The movable plate and the guide block are in a movable state, so the movable plate and the guide block will suddenly deflect inside the box body under the elastic action of the coil spring, and the chips on the movable plate will be fixed first under the action of inertia, so the chips will separate from the movable plate and then fall down, and the movable plate is rotating. After the rotation, the relative position of the chips and the movable plate changes, so the chips will fall toward the end of the movable plate, causing the chips to vibrate on the movable plate, which can improve the moving effect of the chips on the movable plate, reduce the accumulation of chips on the movable plate, and improve the cleaning effect of the chips. The chips falling from the movable plate will be collected in the material trough;

[0019] When the movable plate rises up and resets, the motor reverses, driving the worm gear cylinder to reverse, and the worm gear cylinder drives the movable plate to rotate in the opposite direction and reset first through the coil spring, and when the worm gear cylinder drives the guide rail to deflect, the guide rail will rotate relative to the arc plug rod, so that when the movable plate moves, the arc plug rod remains stationary and continues to push the inclined slot, and the block continues to shrink in the inner wall of the box, so that the movable plate can drive the guide block to move smoothly without being restricted by the block, and when the guide block moves to the upper side of the inclined slot, the arc plug rod moves to the other end of the guide rail, and the continued rotation of the worm gear cylinder drives the arc plug rod to disengage from the slot, and the block extends out and resets under the action of the spring, and when the lower movable plate descends and rotates, the guide block is supported and limited at the lower side;

[0020] When the worm rotates, it drives the first sprocket to rotate. The first sprocket drives the second sprocket and the rotating shaft to rotate through the chain. The rotating shaft drives the discs and convex balls at both ends to rotate. The two groups of convex balls are arranged at ninety degrees. Therefore, when one group of convex balls contacts the convex strips, the other group of convex balls separates from the convex strips. When the two groups of convex balls rotate, they cooperate with the two groups of convex strips to drive the material trough to reciprocate in a fan shape through the fixed column on the inner side of the movable trough, so that the cutting chips in the material trough can be shaken to the left end for unified cleaning.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-9 , an embodiment provided by the present invention:

[0033] The box body 1, movable door 12 and motor 28 used in the present application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described here in detail.

[0034] A fastener cutting device with a chip cleaning function comprises: a box body 1, movable grooves 11 are provided on the left and right side walls of the box body 1, and a movable door 12 is installed on the front of the box body 1;

[0035] A rotating structure 2 is installed on the inner side of the box body 1. The rotating structure 2 includes a movable plate 21. The movable plate 21 is rotatably installed on the inner side of the box body 1 through a rotating shaft. Guide blocks 22 are integrally formed on the left and right side walls of the movable plate 21. A coil spring 23 is fixedly connected to the outer wall of the rotating shaft of the movable plate 21. A worm gear cylinder 24 is sleeved on the outer side of the rotating shaft of the movable plate 21. A guide rail 25 is welded on the outer wall of the worm gear cylinder 24. An arc-shaped plug rod 26 is slidably installed on the surface of the guide rail 25. The left and right side walls of the box body 1 are movably installed with bearings. The worm 27 and the motor 28 are fixedly mounted on the rear wall of the box body 1, and a first sprocket 29 is welded to the middle of the worm 27. The movable plate 21 can be deflected downward to pour the cuttings into the material trough 41. In conjunction with the limiting structure 3, during the deflection process, the cuttings on the surface can be separated from the movable plate 21 by inertia and fall onto the movable plate 21 under the action of gravity, which can improve the moving effect of the cuttings on the movable plate 21, reduce the accumulation of cuttings on the movable plate 21, and improve the cleaning effect of the cuttings.

[0036] Furthermore, a limiting structure 3 is installed inside the box body 1, and the limiting structure 3 includes a card block 31, which is slidably installed on the inner wall of the box body 1. A slot 32 is provided on the surface of the card block 31, and an inclined groove 33 is provided on the inner wall of the slot 32. A spring 34 is fixedly connected to the outer wall of the card block 31. The limiting structure 3 can block the rotating structure 2 when the rotating structure 2 moves, so that the movable plate 21 can move quickly under the elastic action of the coil spring 23, so that the cutting chips are separated from the movable plate 21 under the action of inertia and fall onto the movable plate 21 under the action of gravity, which can improve the moving effect of the cutting chips on the movable plate 21, reduce the accumulation of cutting chips on the movable plate 21, and improve the cleaning effect of the cutting chips.

[0037] Furthermore, a material guiding structure 4 is installed inside the box body 1, and the material guiding structure 4 includes a material trough 41, which is movably installed on the inner side of the movable trough 11, and a fixing column 42 is fixedly connected to the bottom surface of the material trough 41, and a fixing plate 43 is fixedly connected to the right side wall of the material trough 41, and a convex strip 44 is integrally formed on the side wall of the fixing plate 43. A rotating shaft 45 is movably installed on the right side wall of the box body 1 through a bearing, a second sprocket 46 is welded to the middle part of the rotating shaft 45, and a chain 47 is sleeved on the outer side of the second sprocket 46, and a disc 48 is welded to the left and right ends of the rotating shaft 45, and a convex ball 49 is integrally formed on the surface of the disc 48. The material guiding structure 4 can move together when the rotating structure 2 moves, and can guide the cutting chips to the left end for unified cleaning.

[0038] Furthermore, two groups of movable plates 21 are provided, and the two groups of movable plates 21 are installed front and back. The surface of the guide block 22 is in contact with the inner wall of the box body 1, and one end of the coil spring 23 is fixedly connected to the inner wall of the worm gear cylinder 24. The coil spring 23 provides power for the sudden movement of the movable plate 21, thereby improving the cleaning effect of the cutting chips.

[0039] Furthermore, the worm gear cylinder 24 is movably installed inside the housing 1 through a bearing, the worm 27 is meshed with the worm gear cylinder 24, and the output end of the motor 28 is fixedly connected to the worm 27. The motor 28 provides power for the rotation of the worm 27, and the rotation of the worm 27 can drive the worm gear cylinder 24 to rotate.

[0040] Furthermore, the end of the block 31 is exposed from the inner wall of the box body 1, the top surface of the block 31 is fitted with the bottom surface of the guide block 22, the slot 32 and the inclined groove 33 cooperate with the arc-shaped insertion rod 26, and one end of the spring 34 is fixedly connected to the inner wall of the box body 1. The block 31 can limit the guide block 22 on the lower side, so that when the worm gear cylinder 24 is active, the movable plate 21 cannot move, which is convenient for the deformation of the coil spring 23, so that the movable plate 21 can move quickly under the elastic action of the coil spring 23, thereby realizing efficient cleaning of cutting chips, and the arc-shaped insertion rod 26 can be inserted into the slot 32 and push the inclined groove 33 to move the block 31, and the spring 34 provides power for the reset of the block 31.

[0041] Furthermore, the material trough 41 is in a state of being lower on the left and higher on the right, the fixed column 42 is movably installed in the inner wall of the movable groove 11 through a bearing, the fixed plate 43 is exposed to the right side wall of the box body 1 through the movable groove 11, and the cutting chips can move to the left in the material trough 41. The fixed column 42 is a movable limiter at the left end of the material trough 41.

[0042] Furthermore, the upper end of the chain 47 is sleeved on the outer side of the first sprocket 29, the convex balls 49 cooperate with the convex strips 44, and the two groups of convex balls 49 are arranged at ninety degrees. The rotation of the first sprocket 29 can drive the second sprocket 46 to rotate through the chain 47. When one group of convex balls 49 contacts the convex strips 44, the other group of convex balls 49 separates from the convex strips 44, so that the two groups of convex balls 49 can cooperate with the two groups of convex strips 44 when rotating, and can drive the material trough 41 to reciprocate in a fan-shaped movement on the inner side of the movable groove 11 through the fixed column 42, and the cutting chips in the material trough 41 can be shaken to the left end for unified cleaning.

[0043] Working principle: When in use, the fasteners in the box body 1 can be cut through the cutting mechanism, and the cutting chips generated during the processing can fall downward on the top surface of the two sets of movable plates 21;

[0044] After the processing is completed, the motor 28 is started to drive the worm 27 to rotate. The worm 27 meshes with the worm gear cylinder 24. When the worm 27 rotates, it drives the worm gear cylinder 24 to rotate. When the worm gear cylinder 24 rotates, the movable plate 21 is deflected by the coil spring 23, and the guide block 22 on the movable plate 21 is stuck on the top surface of the clamping block 31. The guide block 22 is limited by the clamping block 31, so the movable plate 21 cannot be deflected immediately. Then, when the worm gear cylinder 24 is driven by the worm 27, it will rotate relative to the movable plate 21 on the outside and drive the coil spring 23 to undergo elastic deformation.

[0045] When the worm gear cylinder 24 rotates, it will drive the guide rail 25 to rotate, and the arc-shaped plug rod 26 is slidably connected to the guide rail 25. Therefore, when the worm gear cylinder 24 drives the guide rail 25 to rotate, the arc-shaped plug rod 26 will slide on the guide rail 25 in the opposite direction of the rotation direction. When the arc-shaped plug rod 26 moves to one end of the guide rail 25, the rotation of the worm gear cylinder 24 can drive the arc-shaped plug rod 26 to deflect through the guide rail 25, and the end of the arc-shaped plug rod 26 is inserted in the slot 32. As the worm gear cylinder 24 continues to rotate, the arc-shaped plug rod 26 will be driven to push the inclined groove 33, so that the block 31 is retracted into the inner wall of the box body 1 and squeeze the spring 34, and the block 31 will move away from the bottom surface of the guide block 22, so that the block 31 releases the limit on the guide block 22. Therefore, the movable plate 21 and the guide block 22 are in a movable state, so the movable plate 21 and the guide block 22 will suddenly deflect on the inner side of the box body 1 under the elastic action of the coil spring 23, and the cutting chips on the movable plate 21 will be fixed first under the action of inertia, so the cutting chips will separate from the movable plate 21 and then fall down, and the movable plate 21 is rotating. After the rotation, the relative position of the cutting chips and the movable plate 21 changes, so the cutting chips will fall toward the end of the movable plate 21, so that the cutting chips vibrate on the movable plate 21, which can improve the moving effect of the cutting chips on the movable plate 21, reduce the accumulation of cutting chips on the movable plate 21, and improve the cleaning effect of the cutting chips. The cutting chips falling from the movable plate 21 will be collected in the material trough 41;

[0046] Since the arc-shaped insert rod 26 does not contact the lower group of blocks 31, the lower group of blocks 31 will be fixed, so the lower group of blocks 31 will still limit the guide block 22 at the lower side, so that the movable angle of the movable plate 21 is fixed, and the movable plate 21 can move step by step, thereby improving the vibration effect of the cutting chips;

[0047] When the movable plate 21 rises and resets, the motor 28 reverses, driving the worm gear cylinder 24 to reverse, and the worm gear cylinder 24 drives the movable plate 21 to rotate in the opposite direction and reset first through the coil spring 23. When the worm gear cylinder 24 drives the guide rail 25 to deflect, the guide rail 25 will rotate relative to the arc plug rod 26, so that when the movable plate 21 moves, the arc plug rod 26 remains stationary and continues to push the inclined slot 33, and the block 31 continues to shrink in the inner wall of the box body 1, so that the movable plate 21 can drive the guide block 22 to move smoothly without being restricted by the block 31. When the guide block 22 moves to the upper side of the inclined slot 33, the arc plug rod 26 moves to the other end of the guide rail 25, and the continued rotation of the worm gear cylinder 24 drives the arc plug rod 26 to disengage from the slot 32, and the block 31 extends out and resets under the action of the spring 34, so that when the lower movable plate 21 descends and rotates, the guide block 22 is supported and limited at the lower side;

[0048] When the worm 27 rotates, it drives the first sprocket 29 to rotate. The first sprocket 29 drives the second sprocket 46 and the rotating shaft 45 to rotate through the chain 47. The rotating shaft 45 drives the discs 48 and the convex balls 49 at both ends to rotate. The two groups of convex balls 49 are arranged at ninety degrees. Therefore, when one group of convex balls 49 contacts the convex strips 44, the other group of convex balls 49 is separated from the convex strips 44. When the two groups of convex balls 49 rotate, they can cooperate with the two groups of convex strips 44 to drive the material trough 41 to reciprocate in a fan-shaped manner on the inner side of the movable groove 11 through the fixed column 42, and the cutting chips in the material trough 41 can be shaken to the left end for unified cleaning.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
