Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tools, and specifically relates to an automatic unloading device for CNC machine tools. Background Technology

[0002] Numerical control machine tools are a type of automated machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the numerical control device through an information carrier for machining parts.

[0003] Chinese patent CN215903149U discloses an automatic loading and unloading clamping device for CNC machine tools, including two support plates. Each support plate has a first slide opening on its front side. A first slider is engaged with the inner wall of each first slide opening. The front sides of the two first sliders are fixedly connected to a crossbeam. A second slide opening is opened on the upper surface of the crossbeam. A second slider is engaged with the inner wall of the second slide opening.

[0004] Most of the automatic unloading devices for CNC machine tools in this utility model and existing technologies can adjust the clamping range according to the size of the workpiece. However, when unloading the workpiece, it cannot be placed in the processing area at the time of unloading. It needs to be picked up and placed manually, which increases manpower consumption and wastes resources. At the same time, during the processing of the workpiece, the waste chips cannot be disposed of in time. The accumulated waste chips are easy to cover the surface of the workpiece, resulting in inaccurate workpiece processing and thus affecting the processing quality of the workpiece.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an automatic unloading device for CNC machine tools to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to an automatic unloading device for CNC machine tools, comprising a processing plate and workpieces. A welding plate is fixedly mounted on the top of the processing plate, and a rotating assembly is provided thereon. An unloading assembly is provided at one end of the welding plate. The unloading assembly includes a cylinder, a support plate, a push plate, and a storage bin. The cylinder drives the push plate to reciprocate horizontally through the support plate. Several workpieces are disposed inside the storage bin. The rotating assembly includes a second motor, a bearing plate, and a chip removal groove. The second motor can drive the bearing plate to rotate. A clamping assembly is provided on the top of the bearing plate. The clamping assembly includes a first clamping block, a second clamping block, and a rotating shaft. The rotating shaft can drive the first clamping block and the second clamping block to rotate in opposite directions. One end of the rotating shaft is fixedly connected to the first motor.

[0009] Preferably, the feeding assembly further includes connectors, one end of the two connectors being fixedly connected to the welding plate, and the other end being fixedly connected to the storage tank.

[0010] Preferably, the clamping assembly further includes a fixing block, which is fixedly connected to the top of the support plate.

[0011] Preferably, the clamping assembly further includes a driven shaft, a main gear, and a secondary gear. The rotating shaft and the driven shaft are both rotatably connected to the bearing plate. The first clamping block and the main gear are sleeved on the rotating shaft, and the second clamping block and the secondary gear are sleeved on the driven shaft. The main gear meshes with the secondary gear.

[0012] Preferably, the mounting end of the cylinder is fixedly connected to the welding plate, the support plate is fixedly connected to the output end of the cylinder, and the push plate is fixedly connected to the support plate.

[0013] Preferably, a support frame is fixedly installed at the bottom of the processing plate, the mounting end of the second motor is fixedly connected to the support frame, and the output end of the second motor is fixedly connected to the bottom of the bearing plate.

[0014] Preferably, a baffle is fixedly installed on the top of the processing plate.

[0015] Preferably, the bottom of the support frame is provided with a number of self-locking casters.

[0016] This utility model has the following beneficial effects:

[0017] When a workpiece needs to be processed, the cylinder is activated. When the output end of the cylinder extends, it pushes the support plate to move horizontally. When the support plate moves, it drives the push plate to move. When the push plate moves, it abuts against the workpiece and pushes the workpiece to move. At the same time, the support plate can support the workpiece to be processed, avoiding the situation of incorrect stacking of subsequent workpieces, reducing the time for workers to sort the workpieces, and thus improving work efficiency. By repeatedly pushing the workpiece with the cylinder, the automatic unloading function is achieved, which can save manpower and resources.

[0018] At this point, the first motor is started. The output end of the first motor rotates, driving the rotating shaft to rotate. When the rotating shaft rotates, it drives the first clamping block and the second clamping block to rotate in opposite directions. This reverses the relative rotation of the first clamping block and the second clamping block, allowing them to quickly fix the workpiece. Then, the operator drills a hole in the workpiece and starts the output end of the second motor to rotate in the opposite direction to the drilling equipment. The rotation of the second motor drives the support plate to rotate. When the support plate rotates, it drives the workpiece to rotate through the clamping components, thereby increasing the rotation speed of the workpiece and accelerating the drilling speed. This further improves the workpiece processing efficiency and also removes the waste generated during drilling from the top of the support plate, preventing excessive accumulation of waste and ensuring that the workpiece is not affected by waste during processing, thus improving the processing effect.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figure 1-4 As shown, this utility model is an automatic unloading device for CNC machine tools, including a processing plate 1 and workpieces 10. A welding plate 2 is fixedly installed on the top of the processing plate 1, and a rotating assembly 3 is provided. An unloading assembly 5 is provided at one end of the welding plate 2. The unloading assembly 5 includes a cylinder 501, a support plate 502, a push plate 503, and a storage bin 504. The cylinder 501 drives the push plate 503 to reciprocate horizontally through the support plate 502. Several workpieces 10 are arranged inside the storage bin 504. The rotating assembly 3 includes a first... The system includes a second motor 301, a support plate 302, and a chip removal groove 303. The second motor 301 can drive the support plate 302 to rotate. The chip removal groove 303 is provided on the inner side of the support plate 302. A clamping assembly 6 is provided on the top of the support plate 302. The clamping assembly 6 includes a first clamping block 601, a second clamping block 602, and a rotating shaft 603. The rotating shaft 603 can drive the first clamping block 601 and the second clamping block 602 to rotate in opposite directions. One end of the rotating shaft 603 is fixedly connected to the first motor 607.

[0030] When workpiece 10 needs to be processed, the operator first places several workpieces 10 into the storage bin 504 in sequence, and then starts the cylinder 501. When the output end of the cylinder 501 extends, it pushes the support plate 502 to move horizontally. When the support plate 502 moves, it drives the push plate 503 to move. When the push plate 503 moves, it abuts against the workpiece 10 and pushes the workpiece 10 to move. At the same time, the support plate 502 can support the workpiece 10 to be processed, avoid the situation of stacking errors of the workpieces 10, reduce the time for the operator to sort the workpieces 10, and thus improve work efficiency. When the output end of the cylinder 501 moves to the maximum limit, the workpiece 10 falls into the processing groove on the top of the bearing plate 302 under the action of inertia. By repeatedly pushing the workpiece 10 by the cylinder 501, the automatic unloading function is achieved, which can save manpower and resources.

[0031] At this time, the first motor 607 is started. The output end of the first motor 607 rotates, driving the rotating shaft 603 to rotate. When the rotating shaft 603 rotates, it drives the first clamping block 601 and the second clamping block 602 to rotate in opposite directions. This allows the first clamping block 601 and the second clamping block 602 to quickly fix the workpiece 10 after they rotate in opposite directions, reducing the time of each rotation and further improving work efficiency. Then, the operator drills a hole in the workpiece 10 and starts the output end of the second motor 301 to rotate in the opposite direction to the drilling equipment. The rotation of the output end of the second motor 301 drives the support plate 302 to rotate. When the support plate 302 rotates, it drives the workpiece 10 to rotate through the clamping assembly 6, thereby increasing the rotation of the workpiece 10 and speeding up the drilling speed. This further improves the workpiece processing efficiency and also cleans the waste generated during drilling from the top of the support plate 302, preventing excessive accumulation of waste. This ensures that the workpiece 10 is not affected by waste during processing and improves the processing effect.

[0032] The top of the support plate 302 is provided with a processing groove, and the chip removal groove 303 is opened on the outer wall of the processing groove.

[0033] In one embodiment, the feeding assembly 5 further includes connectors 505, one end of which is fixedly connected to the welding plate 2, and the other end is fixedly connected to the storage tank 504.

[0034] The welding plate 2 is fixed to the storage tank 504 by several connectors 505.

[0035] In one embodiment, the clamping assembly 6 further includes a fixing block 608, which is fixedly connected to the top of the support plate 302.

[0036] The fixed block 608 can support the rotating shaft 603, the driven shaft 604 and the first motor 607, thereby improving stability.

[0037] In one embodiment, the clamping assembly 6 further includes a driven shaft 604, a main gear 605, and a secondary gear 606. Both the rotating shaft 603 and the driven shaft 604 are rotatably connected to the support plate 302. The first clamping block 601 and the main gear 605 are sleeved on the rotating shaft 603, and the second clamping block 602 and the secondary gear 606 are sleeved on the driven shaft 604. The main gear 605 and the secondary gear 606 mesh.

[0038] When the rotating shaft 603 rotates, it drives the first clamping block 601 and the main gear 605 to rotate. When the main gear 605 rotates, it can drive the secondary gear 606 to reverse through meshing with the secondary gear 606. After the secondary gear 606 rotates, it drives the driven shaft 604 to rotate. After the driven shaft 604 rotates, it drives the second clamping block 602 to rotate. Thus, after the first clamping block 601 and the second clamping block 602 reverse relative to each other, the workpiece 10 can be quickly fixed, reducing the time of a single rotation and further improving work efficiency.

[0039] In one embodiment, the mounting end of the cylinder 501 is fixedly connected to the welding plate 2, the support plate 502 is fixedly connected to the output end of the cylinder 501, and the push plate 503 is fixedly connected to the support plate 502.

[0040] This prevents cylinder 501 from being suspended in the air, making the structure more rational.

[0041] In one embodiment, a support frame 7 is fixedly installed at the bottom of the processing plate 1, the mounting end of the second motor 301 is fixedly connected to the support frame 7, and the output end of the second motor 301 is fixedly connected to the bottom of the bearing plate 302.

[0042] The support frame 7 can support the processing plate 1 and the second motor 301, and at the same time raise the height of the processing plate 1, making it easier for the staff to operate.

[0043] In one embodiment, a baffle 8 is fixedly installed on the top of the processing plate 1.

[0044] After the waste chips are thrown out from the top of the support plate 302, they can be blocked by the baffle 8 and stored between the processing plate 1 and the baffle 8, which facilitates the subsequent waste chip treatment.

[0045] In one embodiment, the bottom of the support frame 7 is provided with several self-locking casters 9.

[0046] The self-locking omnidirectional wheel 9 is existing technology and will not be explained here.

[0047] Working principle:

[0048] When workpiece 10 needs to be processed, the operator first places several workpieces 10 into the storage bin 504 in sequence, and then starts the cylinder 501. When the output end of the cylinder 501 extends, it pushes the support plate 502 to move horizontally. When the support plate 502 moves, it drives the push plate 503 to move. When the push plate 503 moves, it abuts against the workpiece 10 and pushes the workpiece 10 to move. At the same time, the support plate 502 can support the workpiece 10 to be processed, avoid the situation of stacking errors of the workpieces 10, reduce the time for the operator to sort the workpieces 10, and thus improve work efficiency. When the output end of the cylinder 501 moves to the maximum limit, the workpiece 10 falls into the processing groove on the top of the bearing plate 302 under the action of inertia. By repeatedly pushing the workpiece 10 by the cylinder 501, the automatic unloading function is achieved, which can save manpower and resources.

[0049] At this time, the first motor 607 is started. After the output end of the first motor 607 rotates, it drives the rotating shaft 603 to rotate. When the rotating shaft 603 rotates, it drives the first clamping block 601 and the main gear 605 to rotate. When the main gear 605 rotates, it can drive the secondary gear 606 to rotate in reverse by meshing with it. After the secondary gear 606 rotates, it drives the driven shaft 604 to rotate. After the driven shaft 604 rotates, it drives the second clamping block 602 to rotate. Thus, after the first clamping block 601 and the second clamping block 602 rotate in opposite directions, the workpiece 10 can be quickly fixed, reducing the time of a single rotation and further improving performance. To improve work efficiency, the operator drills holes in workpiece 10 and starts the output of the second motor 301, which rotates in the opposite direction to the drilling equipment. The rotation of the output of the second motor 301 drives the support plate 302 to rotate. When the support plate 302 rotates, it drives the workpiece 10 to rotate through the clamping assembly 6, thereby increasing the rotation speed of workpiece 10 and accelerating the drilling speed. This further improves the workpiece processing efficiency and also cleans the waste generated during drilling from the top of the support plate 302, preventing excessive accumulation of waste and ensuring that workpiece 10 is not affected by waste during processing, thus improving the processing effect.
