Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and more specifically to a parts processing and cutting machine. Background Technology

[0002] In the processing of metal parts, especially aluminum components, cutting and grinding are two key processes. Traditional cutting equipment mainly focuses on achieving efficient, fixed-length cutting of materials, typically using a cutting disc as the primary cutting tool. However, due to issues such as tool wear, burrs in the heat-affected zone, or rough cut surfaces during the cutting process, the ends of the cut workpieces need further grinding to meet assembly or functional requirements.

[0003] In existing technologies, grinding is often performed as a separate process after cutting, requiring the workpiece to be transported from the cutting station to the grinding station for further processing. This separate processing mode has significant drawbacks: First, the processing cycle is fragmented, necessitating interruptions for transfer, which significantly reduces production efficiency; second, the equipment layout is complex, requiring frequent manual or mechanical intervention, increasing labor intensity and the risk of errors; third, the cut surface is prone to oxidation or collision damage during transport, affecting the quality and consistency of subsequent grinding. Furthermore, the end face structure of the cutting disc is usually planar or solidly closed, lacking an effective chip guiding structure, resulting in poor chip removal, easy clogging of the cutting area, and impact on processing stability and tool life.

[0004] Therefore, existing technologies still suffer from problems such as low production efficiency, functional area interference, low chip removal efficiency, and insufficient grinding in the integrated collaborative operation of cutting and grinding. Based on this, we propose a parts processing cutting machine. Summary of the Invention

[0005] In order to solve the technical problems existing in the prior art, the present invention provides a parts processing and cutting machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a parts processing and cutting machine, comprising a frame, a cutting groove formed at the upper end of the frame along its length, a mounting frame slidably mounted below the cutting groove along its length, a rotatable cutting disc installed inside the mounting frame, the cutting disc extending into the cutting groove, movable chambers formed on both sides of the cutting disc, and grinding rings slidably mounted in the movable chambers in a direction perpendicular to the cutting disc, the end face of the grinding rings having a flat portion; during cutting operations, the grinding rings are embedded in the movable chambers, and a temporary cutting cavity with a groove structure is formed between the outer surface of the grinding rings and the inner wall of the movable chambers; during grinding operations, the two grinding rings move synchronously in a straight line away from the cutting disc until they protrude from the end face of the cutting disc and contact the cross-section of the parts.

[0007] Preferably, a first sprocket is fixedly sleeved at the center of the cutting disc via a sleeve, a motor is installed inside the mounting frame, a second sprocket is fixedly sleeved on the motor shaft of the motor, and a chain belt is sleeved between the second sprocket and the first sprocket.

[0008] Preferably, an electric cylinder is fixedly installed inside the frame, and the piston rod of the electric cylinder is fixedly connected to the mounting bracket.

[0009] Preferably, a movable shaft is slidably sleeved inside the sleeve, and one end of the movable shaft is fixedly connected to the grinding ring; the outer circumferential surface of the movable shaft is integrally formed with ribs along its axial direction, the inner wall of the sleeve is provided with ribs, and the inner wall of the sleeve is provided with guide grooves that are adapted to the ribs.

[0010] Preferably, the outer surface edge of the grinding ring is provided with an inwardly inclined bevel; the depth of the temporary cutting cavity gradually increases from the inside to the outside.

[0011] Preferably, in the initial state, the end face of the grinding ring and the end face of the cutting disc remain flush; as the cutting operation proceeds, the two grinding rings move synchronously toward the cutting disc.

[0012] Preferably, a lifting rod is installed at the other end of the movable shaft; a guide plate is fixedly installed inside the frame at the position corresponding to the mounting bracket, and a guide rod is fixedly installed in the mounting bracket at the position corresponding to the guide plate; the guide plate is slidably assembled inside the frame in the vertical direction, and a guide groove is opened on the end face of the guide plate near the guide rod, and the lifting rod is slidably assembled in the guide groove; a rising protrusion is fixedly installed on one side of the upper end of the guide plate, and a spring is fixedly installed on the other side of the lower end of the guide plate, and the end faces of the rising protrusion and the spring that are close to each other are inclined outwards, and both the rising protrusion and the spring are adapted to the guide rod.

[0013] Preferably, the guide groove consists of a working section, a descending section, a resetting section, and an ascending section connected in series. The working section has an outwardly inclined structure, the descending section and the ascending section are both arranged in the vertical direction, and the resetting section consists of an inclined part and a horizontal part, with the inclined part inclined in the direction away from the lifting rod.

[0014] Compared with the prior art, the present invention provides a parts processing and cutting machine, which has the following beneficial effects:

[0015] (1) In this invention, the aluminum material is precisely cut during the forward movement of the cutting disc. When the cutting disc returns to its original position after completing the operation, the two grinding rings move synchronously away from the cutting disc and protrude from the end face of the cutting disc. They actively fit against the cut end of the aluminum material for grinding. A gap is formed between the cutting disc and the end face of the workpiece, which effectively avoids interference from the cutting disc in the grinding process and prevents the cutting edge from scratching the ground surface. At the same time, the grinding rings can fully contact the end face, improving the grinding uniformity and surface quality.

[0016] (2) During the grinding operation, the grinding ring protrudes from the cutting disc, which spatially isolates the grinding functional area from the cutting functional area, forming a stable processing rhythm, which is conducive to realizing automated control and motion path logic optimization.

[0017] (3) A temporary chip chamber is provided at the end of the cutting disc. The chamber has a sloping structure with increasing depth from the inside to the outside, which can dynamically adapt to the increasing chip volume as the cutting progress progresses, enhance the natural chip discharge capability, avoid chip blockage and high temperature heat accumulation in the cutting zone, and at the same time maintain a reasonable strength distribution of the cutting disc structure, effectively improving cutting stability and tool life.

[0018] (4) During the cutting operation, the grinding ring moves towards the cutting disc and partially embeds itself into the cutting disc, thereby dynamically increasing the depth of the temporary chip cavity. This allows a large number of chips generated during the cutting process to be discharged smoothly, avoiding blockage of the cutting path, interference of the cutting disc, or a decrease in cutting efficiency due to chip accumulation. In addition, the deeper chip cavity enhances the heat release channel, improves the heat dissipation effect of the contact area between the cutting disc and the parts, reduces the adverse effects of cutting heat on tool life and cross-sectional quality, and helps to improve machining stability.

[0019] (5) The temporary chip chamber and the grinding ring work together to improve the overall processing quality, cycle continuity and system operation reliability of the device, realize the integrated and efficient processing of cutting and grinding, reduce manual intervention, improve production efficiency and have good industrial application prospects.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] This embodiment proposes a parts processing and cutting machine, such as... Figures 1 to 12As shown, the device includes a frame 1. A cutting groove 2 is formed at the upper end of the frame 1 along its length. A mounting frame 5 is slidably mounted below the cutting groove 2 along its length. A rotatable cutting disc 3 is installed inside the mounting frame 5, extending into the cutting groove 2. Clamping cylinder assemblies 7 for holding parts are also provided on both sides of the cutting groove 2. In this embodiment, a first sprocket 33 is fixedly sleeved at the center of the cutting disc 3 via a sleeve 32. A motor 36 is installed inside the mounting frame 5, and a second sprocket 33 is fixedly sleeved on the motor shaft of the motor 36. A chain belt 35 is sleeved between the sprocket 34, the second sprocket 34, and the first sprocket 33. An electric cylinder 6 is fixedly installed inside the frame 1, and the piston rod of the electric cylinder 6 is fixedly connected to the mounting bracket 5. When performing the cutting operation, the part to be cut is first placed on one side of the cutting disc 3, and the part is fixed by the clamping cylinder assembly 7. The motor 36 is started, driving the cutting disc 3 to rotate at high speed. Then, the electric cylinder 6 is started, and the piston rod of the electric cylinder 6 extends, driving the cutting disc 3 along the cutting groove 2 and towards the part. When the cutting disc 3 comes into contact with the component, the cutting force generated by its high-speed rotation is used to cut the component. After cutting, due to wear of the cutting tool during use, the ends of the cut components often have burrs or roughness. It is necessary to remove burrs and finish the surface of the component. Therefore, in this invention, movable chambers 31 are provided on both sides of the cutting disc 3. Grinding rings 4 are slidably mounted in the movable chambers 31 in a direction perpendicular to the cutting disc 3. The end face of the grinding rings 4 is provided with a flat part 44. After the cutting operation is completed, the piston rod of the electric cylinder 6 retracts and drives the cutting disc 3 to return to its original position. During this process, the two grinding rings 4 move in a straight line in a direction away from the cutting disc 3 until the flat part 44 protrudes from the end face of the cutting disc 3 and contacts the cross-section of the component. They actively conform to the cut surface of the component to perform grinding operation. During this process, the grinding rings 4 are away from the area of ​​the cutting disc 3, which helps to isolate the heat source and allows the grinding operation to be carried out in a relatively cooled state, preventing grinding errors or "pasteurization" of the grinding layer surface caused by factors such as thermal expansion and contraction and thermal adhesion. In this embodiment, a cross link 43 is provided in the middle region of the grinding ring 4. The cross link 43 is slidably assembled in the movable chamber 31, and the movement stroke of the grinding ring 43 is limited by the cross link 43. A sleeve 32 is fixedly installed at the center of both ends of the grinding ring 4. A movable shaft 45 is slidably sleeved in the sleeve 32. One end of the movable shaft 45 is fixedly connected to the grinding ring 4. Ribs are integrally formed on the outer circumference of the movable shaft 45 along its axial direction. Ribs are provided on the inner wall of the sleeve 32. Guide grooves adapted to the ribs are provided on the inner wall of the sleeve 32. The ribs and guide grooves enable the movable shaft 45 to both rotate and move linearly within the sleeve 32.

[0040] During the cutting process, chips accumulate in the cutting area between the grinding ring 4 and the cross-section of the part, which increases cutting resistance and heat accumulation. To address this, during the cutting process, the grinding ring 4 is embedded in the movable chamber 31, forming a temporary cutting cavity 41 with a groove structure between the outer surface of the grinding ring 4 and the inner wall of the movable chamber 31. The temporary cutting cavity 41 provides a larger chip space for the cutting area, preventing chips from accumulating between the cutting disc 3 and the part, and reducing cutting resistance and heat accumulation.

[0041] Based on the above scheme, if the depth of the temporary cutting cavity 41 is shallow, as the chips formed during the cutting process accumulate rapidly, if the residual chips remain in the cutting path, they are easily pressed repeatedly into the cutting surface, causing scratches, burrs, or even chipping of the cross-section. It will also lead to increased friction between the grinding ring 4 and the chips, resulting in increased heat generation during cutting, which can easily cause the tool to burn or break. If the depth of the temporary cutting cavity 41 is deep, the structural strength of the central area of ​​the grinding ring 4 will be reduced, affecting the rigidity and service life of the grinding ring 4. In addition, the chip capacity is much greater than the actual requirement, resulting in machining redundancy and wasted costs. Therefore, in this embodiment, an inwardly inclined beveled surface 42 is provided at the outer surface edge of the grinding ring 4. The depth of the temporary cutting cavity 41 gradually increases from the inside to the outside through the movable chamber 31. The chips are initially concentrated in the shallow groove area of ​​the temporary cutting cavity 41. As the cutting area increases, the chips can transition to a deeper area. Under the combined action of centrifugal force and gravity, the chips are discharged outward along the depth gradient, reducing chip backflow and accumulation, and reducing the risk of chip blockage and overheating.

[0042] The inclined structure of the movable chamber 31 provides guidance, allowing chips to slide naturally along the slope and be discharged. In the initial cutting stage, the contact area is small and the amount of chips is small, so the chip chamber only needs to maintain a small space capacity. As the cutting progresses, the material contact area expands and the amount of chips increases rapidly. At this time, a larger cavity is needed to accommodate the chips and a faster discharge path. Therefore, in this invention, in the initial state, the end face of the grinding ring 4 and the end face of the cutting disk 3 are kept flush. During the cutting operation, the two grinding rings 4 move synchronously toward the cutting disk 3, so that the depth of the temporary cutting chamber 41 gradually increases, the space capacity and chip discharge speed are increased simultaneously, and the adaptability and versatility of the temporary cutting chamber 41 to different working conditions are improved.

[0043] In addition, to further improve the coordination between cutting and grinding operations, this invention transforms the linear reciprocating motion of the grinding ring 4 into the relative motion of two grinding rings 4. Specifically, a lifting rod 46 is installed at the other end of the movable shaft 45; a guide plate 9 is fixedly installed inside the frame 1 at a position corresponding to the mounting bracket 5, and a guide rod 8 is fixedly installed in the mounting bracket 5 at a position corresponding to the guide plate 9; the guide plate 9 is slidably assembled inside the frame 1 in the vertical direction, and a guide groove 93 is opened on the end face of the guide plate 9 near the guide rod 8, and the lifting rod 46 is slidably assembled in the guide groove 93; the upper end of the guide plate 9... A rising protrusion 91 is fixedly installed on one side, and a spring 92 is fixedly installed on the other side of the lower end of the guide plate 9. The end faces of the rising protrusion 91 and the spring 92 that are close to each other are inclined outwards. The rising protrusion 91 and the spring 92 are both adapted to the guide rod 8. The guide groove 93 is composed of a working section 931, a descending section 932, a reset section 933 and a rising section 934 connected in series. The working section 931 has an outwardly inclined structure. The descending section 932 and the rising section 934 are both set in the vertical direction. The reset section 933 is composed of an inclined part and a horizontal part. The inclined part is inclined in the direction away from the lifting rod 46. Initially, the lifting rod 46 is located at the junction of the working section 931 and the rising section 934. As the cutting operation progresses, 939 moves from the working section 931 towards the descending section 932. At this time, since the working section 931 is inclined towards the lifting rod 46, the other end of the lifting rod 46 drives the grinding ring 4 to move towards the cutting disc 3, increasing the depth of the temporary cutting cavity 41 to accommodate the gradually increasing amount of debris. Simultaneously, the guide rod 8 moves towards the rising protrusion 91. When the lifting rod 46 moves to the junction of the working section 931 and the descending section 932, the guide rod 8 just contacts the rising protrusion 91. At this time, the guide plate 9 moves vertically upward, and the lifting rod 46 moves along the descending section 932 towards the reset section 93. 3. During the movement, the spring 92 is in a compressed state. When the lifting rod 46 moves to the junction of the descending section 932 and the reset section 933, the cutting operation is completed. As the piston rod of the electric cylinder 6 retracts, the lifting rod 46 moves along the reset section 933. When the lifting rod 46 enters the inclined section, since the inclined section is tilted away from the grinding ring 4, the other end of the lifting rod 46 drives the grinding ring 4 to move away from the cutting disc 3. When the lifting rod 46 enters the horizontal section, the grinding ring 4 contacts the cross-section of the part for grinding. When the lifting rod 46 moves to the junction of the reset section 933 and the rising section 934, the spring 92 applies a downward force to the guide plate 9, and the lifting rod 46 moves to the initial position through 94, waiting for the next cutting operation.
