Description

Technical Field

[0001] The present invention relates to the technical field of metal processing, and particularly to a cutting machine for processing parts. Background Art

[0002] In the processing of metal parts, especially aluminum components, cutting and grinding are two key processes. Traditional cutting and processing equipment mainly focuses on achieving efficient fixed-length cutting of materials, and usually uses a cutting disc as the main cutting tool. However, due to problems such as tool wear during cutting, burrs generated in the heat-affected zone, or rough cut-off surfaces, the end of the workpiece after cutting needs to be further ground to meet assembly or functional requirements.

[0003] In the prior art, the grinding operation is often set as an independent process after cutting, and the workpiece needs to be transported from the cutting station to the grinding station for subsequent processing. This separated processing mode has obvious drawbacks: firstly, the processing rhythm is segmented, and it is necessary to interrupt the operation for transfer, greatly reducing the production efficiency; secondly, the equipment layout is complex, and manual or mechanical intervention is frequent, increasing the labor intensity and the risk of errors; thirdly, the cut-off surface is prone to oxidation or collision damage during the transportation process, affecting the subsequent grinding quality and consistency. In addition, the end face structure of the cutting disc is usually flat or solid-closed, lacking an effective chip guiding structure, and the chips are not discharged smoothly, easily blocking the cutting area and affecting the processing stability and tool life.

[0004] Therefore, the prior art still has problems such as low production efficiency, interference in functional areas, low chip removal efficiency, and insufficient grinding in the integrated collaborative operation of cutting and grinding. Based on this, we propose a cutting machine for processing parts. Summary of the Invention

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

[0006] To achieve the above object, the present invention provides the following technical solution: A cutting machine for processing parts includes a machine frame. A cutting groove is opened along the length direction at the upper end of the machine frame. An installation frame is slidably assembled along the length direction of the cutting groove directly below the cutting groove. A rotatable cutting disc is installed inside the installation frame, and the cutting disc extends into the cutting groove. Activity chambers are opened on both sides of the cutting disc. A grinding ring is slidably assembled in the activity chamber along a direction perpendicular to the cutting disc, and a flat portion is provided on the end face of the grinding ring; during the cutting operation, the grinding ring is embedded in the activity chamber, and a temporary cutting chamber with a groove structure is formed between the outer surface of the grinding ring and the inner wall of the activity chamber; during the grinding operation, 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 part.

[0007] Preferably, a first sprocket is fixedly sleeved on the center of the cutting disc through a sleeve, a motor is installed inside the mounting frame, a motor shaft of the motor is fixedly sleeved with a second sprocket, 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 a piston rod of the electric cylinder is fixedly connected to the mounting frame.

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

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

[0011] Preferably, in the initial state, the end face of the grinding ring and the end face of the cutting disc are flush; as the cutting operation progresses, the two grinding rings move synchronously towards the direction close to 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 corresponding to the position of the mounting frame, and a guide rod is fixedly installed at the position of the mounting frame corresponding to the guide plate; the guide plate is slidably assembled inside the frame in the vertical direction, a guide groove is provided on the end face of the guide plate close to the guide rod, and the lifting rod is slidably assembled in the guide groove; a rising convex block is fixedly installed on one side of the upper end of the guide plate, a spring is fixedly installed on the other side of the lower end of the guide plate, the end faces of the rising convex block and the spring close to each other are inclined outwardly, and both the rising convex block and the spring are adapted to the guide rod.

[0013] Preferably, the guide groove is sequentially connected end to end by an operation section, a descending section, a reset section and a rising section, the operation section is of an outwardly inclined structure, both the descending section and the rising section are arranged in the vertical direction, and the reset section is composed of an inclined portion and a horizontal portion, and the inclined portion is inclined in the direction away from the lifting rod.

[0014] Compared with the prior art, the present invention provides a parts processing cutting machine, which has the following beneficial effects: (1) In the present invention, during the forward movement of the cutting disc, precise cutting of the aluminum material is completed. When the cutting disc completes the operation and returns backward, the two grinding rings move synchronously away from the cutting disc and protrude from the end face of the cutting disc, actively fitting the cut end of the aluminum material for grinding. A gap is formed between the cutting disc and the end face of the workpiece, effectively avoiding the interference of the cutting disc on the grinding process, preventing the cutting edge from scratching the already ground surface, and at the same time enabling the grinding ring to fully contact the end face, improving the grinding uniformity and surface quality.

[0015] (2)During the grinding operation, the grinding ring protrudes from the cutting disc, spatially isolating the grinding function area from the cutting function area, forming a stable processing rhythm, which is conducive to realizing automatic control and optimizing the motion path logic.

[0016] (3)A temporary chip chamber is provided at the end of the cutting disc. This chamber has an inclined surface structure with an increasing depth from the inside to the outside, so that as the cutting progresses, it can dynamically adapt to the gradually increasing chip volume, enhance the natural chip discharge ability, avoid chip jamming and high-temperature heat accumulation in the cutting area, and at the same time maintain a reasonable strength distribution of the cutting disc structure, effectively improving cutting stability and tool life.

[0017] (4)During the cutting operation, the grinding ring moves towards the direction close to the cutting disc and partially embeds into the cutting disc, thereby dynamically increasing the depth of the temporary chip chamber, enabling a large amount of debris 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 caused by chip accumulation; in addition, the deeper chip chamber enhances the heat release channel, improves the heat dissipation effect in the contact area between the cutting disc and the components, reduces the adverse impact of cutting heat on tool life and section quality, and helps to improve processing stability.

[0018] (5)The combined action of the temporary chip chamber and the grinding ring improves the overall processing quality, beat continuity, and system operation reliability of the device, realizes the integrated and efficient processing of cutting and grinding, reduces manual intervention, improves production efficiency, and has good industrial application prospects.

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can 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 present invention, but only represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0022] This embodiment proposes a parts processing cutting machine, such as Figures 1 to 12As shown in the figure, it includes a machine frame 1. A cutting groove 2 is provided at the upper end of the machine frame 1 along its length direction. A mounting frame 5 is slidably assembled along the length direction of the cutting groove 2 directly below the cutting groove 2. A rotatable cutting disc 3 is installed inside the mounting frame 5, and the cutting disc 3 extends into the cutting groove 2. Clamping cylinder groups 7 for clamping components are also provided on both sides of the cutting groove 2. In this embodiment, a first sprocket 33 is fixedly sleeved on the center of the cutting disc 3 through a sleeve 32. A motor 36 is installed inside the mounting frame 5, and a second sprocket 34 is fixedly sleeved on the motor shaft of the motor 36. A chain belt 35 is sleeved between the second sprocket 34 and the first sprocket 33. An electric cylinder 6 is fixedly installed inside the machine frame 1, and the piston rod of the electric cylinder 6 is fixedly connected to the mounting frame 5. When performing the cutting operation of the component, first place the component to be cut on one side of the cutting disc 3, fix the component through the clamping cylinder groups 7, start the motor 36, drive the cutting disc 3 to rotate at a high speed through the motor 36, and then start the electric cylinder 6. The piston rod of the electric cylinder 6 extends and drives the cutting disc 3 to move along the cutting groove 2 and towards the component until the cutting disc 3 contacts the component, and use the cutting force generated by its high-speed rotation to perform the cutting operation on the component. After the cutting is completed, since the cutting tool will wear during use, there are often burrs or unevenness on the end of the component after cutting, and it is necessary to remove the burrs and finish the surface of the component end face. Therefore, in the present invention, movable chambers 31 are provided on both sides of the cutting disc 3. A polishing ring 4 is slidably assembled in the movable chamber 31 along the direction perpendicular to the cutting disc 3. A flat portion 44 is provided on the end face of the polishing ring 4. After the cutting operation is completed, the piston rod of the electric cylinder 6 contracts and drives the cutting disc 3 to reset. During this process, the two polishing rings 4 move linearly in the direction away from the cutting disc 3 synchronously until the flat portion 44 protrudes from the end face of the cutting disc 3 and contacts the cross section of the component, and actively fits the cut surface of the component for polishing operation. During this process, in the area where the polishing ring 4 is far from the cutting disc 3, it helps to isolate the heat source, so that the polishing operation is carried out in a relatively cooled state, preventing polishing errors or "gelatinization" on the surface of the polishing layer caused by factors such as thermal expansion and contraction and thermal adhesion. In this embodiment, a cross link 43 is provided in the middle area of the polishing ring 4, and the cross link 43 is slidably assembled in the movable chamber 31 to limit the movement stroke of the polishing ring 43 through the cross link 43. Fixedly installed at the center of both ends of the polishing ring 4 are sleeves 32. A movable shaft 45 is slidably sleeved in the sleeve 32, and one end of the movable shaft 45 is fixedly connected to the polishing ring 4. Ribs are integrally formed on the outer circumferential surface of the movable shaft 45 along its axial direction, and guide grooves are provided on the inner wall of the sleeve 32. The ribs and the guide grooves enable the movable shaft 45 to rotate and also perform linear movement in the sleeve 32.

[0023] During the cutting operation, debris accumulates in the cutting area between the grinding ring 4 and the cross-section of the component, thereby increasing the cutting resistance and heat accumulation. Therefore, during the cutting operation, the grinding ring 4 is embedded in the movable chamber 31, so that a temporary cutting chamber 41 with a groove structure is formed between the outer surface of the grinding ring 4 and the inner wall of the movable chamber 31. The temporary cutting chamber 41 provides a larger chip-holding space for the cutting area, preventing debris from accumulating between the cutting disc 3 and the component, and reducing the cutting resistance and heat accumulation.

[0024] Based on the above solution, if the depth of the temporary cutting chamber 41 is relatively shallow, as the debris formed during the cutting process accumulates rapidly, if the residual chips remain in the cutting path, they are easily pressed into the cutting surface repeatedly, causing scratches, burrs, and even chipping on the edge of the cross-section. It will also lead to increased friction between the grinding ring 4 and the debris, resulting in an increase in the cutting heat generation, and being prone to tool burning and tool breakage. If the depth of the temporary cutting chamber 41 is relatively 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-holding capacity is much larger than the actual requirement, causing processing redundancy and wasting costs. Therefore, in this embodiment, an inclined surface portion 42 that inclines inward is provided at the outer surface edge of the grinding ring 4; through the movable chamber 31, the depth of the temporary cutting chamber 41 gradually increases from the inside to the outside. The chips initially concentrate in the shallow groove area of the temporary cutting chamber 41. As the cutting area increases, the chips can transition to deeper areas. 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 jamming and overheating.

[0025] Through the guiding action generated by the inclined surface structure of the movable chamber 31, the chips naturally slide out along the slope. In the initial cutting stage, the contact area is small and the chip amount is small, and the chip removal chamber only needs to maintain a small space capacity; as the cutting progresses, the material contact area expands and the chips increase rapidly. At this time, a larger cavity is required for accommodation and a faster discharge path. Therefore, in the present invention, in the initial state, the end surface of the grinding ring 4 and the end surface of the cutting disc 3 are flush; during the cutting operation, the two grinding rings 4 move synchronously towards the direction close to the cutting disc 3, so that the depth of the temporary cutting chamber 41 gradually increases, and the space capacity and chip discharge speed are improved synchronously, enhancing the self-adaptability and versatility of the temporary cutting chamber 41 to different working conditions.

[0026] In addition, in order to further improve the coordination between the cutting operation and the grinding operation, in the present invention, the linear reciprocating motion of the grinding ring 4 is converted 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 corresponding to the position of the mounting bracket 5, and a guide rod 8 is fixedly installed at the position of the mounting bracket 5 corresponding to the guide plate 9; the guide plate 9 is slidably assembled inside the frame 1 in the vertical direction, a guide groove 93 is formed in the end face of the guide plate 9 close to the guide rod 8, and the lifting rod 46 is slidably assembled in the guide groove 93; a rising convex block 91 is fixedly installed on one side of the upper end of the guide plate 9, 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 convex block 91 and the spring 92 close to each other are inclined outwardly, and both the rising convex block 91 and the spring 92 are adapted to the guide rod 8; the guide groove 93 is sequentially connected end to end by an operation section 931, a descending section 932, a reset section 933 and a rising section 934. The operation section 931 has an outwardly inclined structure, and both the descending section 932 and the rising section 934 are arranged in the vertical direction. The reset section 933 is composed of an inclined part and a horizontal part, and the inclined part is inclined in a direction away from the lifting rod 46. In the initial state, the lifting rod 46 is located at the junction of the operation section 931 and the rising section 934. As the cutting operation progresses, 939 moves from the operation section 931 towards the descending section 932. At this time, since the operation section 931 is inclined in a direction close to the lifting rod 46, the other end of the lifting rod 46 drives the grinding ring 4 to move towards the direction close to the cutting disc 3, so that the depth of the temporary cutting cavity 41 increases to adapt to the gradually increasing amount of debris. At the same time, the guide rod 8 moves towards the direction close to the rising convex block 91; when the lifting rod 46 moves to the junction of the operation section 931 and the descending section 932, the guide rod 8 just contacts the rising convex block 91. At this time, the guide plate 9 moves upward in the vertical direction, and the lifting rod 46 moves along the descending section 932 towards the reset section 933, and at the same time 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 contracts, the lifting rod 46 moves along the reset section 933. When the lifting rod 46 enters the inclined section, since the inclined section is inclined in a direction 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 component for grinding operation; when the lifting rod 46 moves to the junction of the reset section 933 and the rising section 934, the spring 92 exerts a downward force on the guide plate 9, and the lifting rod 46 moves to the initial position through 94, waiting for the next cutting operation.
