Description

[0002] In modern manufacturing, processing metal rods into columnar parts is a common and basic processing technology. In order to ensure the quality of the columnar parts after processing and forming, after the metal rods are cut, the cross-section of the generated columnar parts often needs to be ground and polished.

[0003] The relevant machine tool equipment in the prior art usually adopts a high-speed rotating cutting tool to realize the cutting operation of the metal rod, and uses a grinding disc to grind and polish the cut surface after the cutting is completed. In the actual operation process, since the metal rod is conveyed into the machine tool equipment along the central axis direction, and the cutting and grinding working surface is perpendicular to the axial conveying direction of the metal rod, the conveying of the metal rod has to be suspended during the cutting and grinding process. Only after the cutting and grinding are completed, the feeding and conveying of the metal rod can be resumed. During this period, the equipment has a lot of idle time, and the processing mode of frequently interrupting the metal rod conveying greatly restricts the production efficiency and increases the processing time of a single columnar part, which makes it difficult to meet the current growing demand for efficient production.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment: This embodiment provides a parts processing and cutting machine, see Figure 1 - Fig.10Specifically, it includes a base 1, two front and rear symmetrically arranged conveying wheels 2 are rotatably installed on the top right side of the base 1, a metal rod for processing into a columnar part is clamped between the front and rear conveying wheels 2, a synchronous moving mechanism located on the left side of the two conveying wheels 2 is installed on the top of the base 1, and the synchronous moving mechanism includes an outer frame 3 installed on the top of the base 1 for transverse sliding, a first electric clamp 301 is installed on the right end of the outer frame 3, a lifting platform 302 for lifting up and down is installed in the outer frame 3, and a horizontally arranged rotating shaft 303 is rotatably installed in the lifting platform 302, a cutting wheel 304 is fixedly installed on the right end of the rotating shaft 303, and a sleeve located on the left side of the cutting wheel 304 is sleeved on the rotating shaft 303 The outer frame 3 is provided with a first V-shaped block 308 which is evenly distributed from right to left. The back of the outer frame 3 is provided with a first connecting plate 4 which is fixedly installed. A second electric push rod 401 which is located on the left side of the synchronous moving mechanism is laterally fixedly provided at the rear of the top of the base 1. The telescopic end of the second electric push rod 401 faces the first connecting plate 4. A first chamfering mechanism which is located on the left side of the synchronous moving mechanism is installed at the top of the base 1. A second chamfering mechanism which is located on the lower side of the first chamfering mechanism is provided.

[0021] When the device is in use, the staff connects the device to an external power supply so that the external power supply provides power support for the device. Then the staff can control the device to start, cut, grind and chamfer the edges of the long and straight metal rod, and process the long and straight metal rod into a plurality of cylindrical parts of equal length. During the processing, the long and straight metal rod is inserted between two front and rear symmetrical conveying wheels 2. Through the relative rotation of the two conveying wheels 2, the metal rod is continuously conveyed from right to left at a uniform speed. When the metal rod enters the predetermined position in the synchronous moving mechanism, the first electric clamp 301 installed at the right end of the outer frame 3 is controlled to start and clamp on the metal rod. In the process of the metal rod being conveyed to the left at a uniform speed, the outer frame 3 is driven to move synchronously to the left. During this process, the servo motor installed at one end of the lifting platform 302 is powered on and started. The driving shaft of the servo motor is connected to the rotating shaft 303, which drives the rotating shaft 303 to drive the cutting wheel 304 and the grinding wheel 304. The grinding wheel 306 rotates at a high speed, and synchronously, the first electric push rod 307 installed on the outer frame 3 is powered on and started, controlling the lifting platform 302 to move downward in the outer frame 3, thereby driving the high-speed rotating cutting wheel 304 and the grinding wheel 306 to move downward synchronously. Along with the downward movement of the high-speed rotating cutting wheel 304, the cutting operation of the metal rod can be completed during the transportation process. The distance between the grinding wheel 306 and the cutting wheel 304 is consistent with the length of a single columnar part. When the cutting wheel 304 moves downward to cut the metal rod to generate a new columnar part, the grinding wheel 306 moves downward synchronously, intrudes between the above-mentioned columnar part and the previous columnar part, and grinds the left end wall of the above-mentioned columnar part box and the right end of the previous columnar part. After the cutting is completed, the first electric push rod 307 controls the lifting platform 302 to move up and reset, so that the cutting wheel 304 moves up and out of the range of the metal rod. Synchronously, the grinding wheel 306 moves up and out of the range of the columnar part.

[0022] Then, the first electric clamp 301 releases its clamping of the metal rod, so that the outer frame 3 is no longer firmly connected to the metal rod, and the second electric push rod 401 is powered on and started, and its telescopic end moves to the right at high speed, acting on the first connecting plate 4, pushing the outer frame 3 to the right and resetting it to the initial position. The speed of the outer frame 3 moving to the right and resetting under the push of the second electric push rod 401 is much faster than the speed of the metal rod being transported to the left. When the outer frame 3 moves to the right and resetting, the first electric clamp 301 just corresponds to the next predetermined clamping position on the metal rod, and the lifting platform 302 clamps the metal rod again, so that the synchronous moving mechanism moves synchronously with the metal rod again. During the synchronous movement process, the operation of cutting the metal rod into columnar parts of equal length and the operation of grinding the cross section of the columnar parts are realized.

[0023] The device is implemented by sliding an outer frame 3 on the top of a base 1 along the conveying direction of the metal rod, and installing a first electric clamp 301 for clamping the metal rod at one end of the outer frame 3, so that after the first electric clamp 301 clamps the metal rod, the synchronous moving mechanism can move synchronously with the metal rod, and with the help of the high-speed push of the second electric push rod 401, the synchronous moving mechanism is driven to move in the opposite direction and reset. In the cycle, the synchronous movement of the cutting wheel 304 and the grinding wheel 306 and the metal rod can be achieved during the axial conveying of the metal rod, and then the cutting of the metal rod and the grinding of the cut surface are completed during the movement. There is no need to intermittently convey the metal rod, which can effectively improve the efficiency of the metal rod being cut and ground to a fixed length. Then, the columnar part generated by the fixed-length cutting of the metal rod continues to move to the left, and is processed by the first chamfering mechanism and the second chamfering mechanism in turn, so as to achieve the chamfering operation on the edge positions of the cut surfaces at both ends of the columnar part.

[0024] In the specific implementation process, Figure 2 As shown, a circumferential groove is provided in the middle of the cylindrical surface of the conveying wheel 2, and a gear 201 is fixedly installed at the lower end of each conveying wheel 2, and the two gears 201 are meshed with each other. When the device is in use, the circumferential groove provided on the cylindrical surface of the conveying wheel 2 is adapted to the outer size of the metal rod, which allows the metal rod to be embedded in the groove during the conveying process, which is beneficial to increasing the contact area between the conveying wheel 2 and the metal rod. A servo motor is installed inside the right end of the base 1, and the driving shaft of the servo motor is connected to one of the conveying wheels 2. The conveying wheel 2 is driven to rotate by the servo motor. Since the gears 201 are fixedly installed at the lower ends of the two conveying wheels 2, and the two gears 201 are meshed with each other, the synchronous relative rotation of the two conveying wheels 2 is more stable. Through the stable synchronous relative rotation of the two conveying wheels 2, stable conveying of the metal rod can be achieved.

[0025] In the specific implementation process, Figure 3As shown, the outer shape of the rotating shaft 303 is set to a prismatic structure, and the sleeve 305 is slidably sleeved on the rotating shaft 303. The sleeve 305 is fastened to the rotating shaft 303 by bolts. When the device is used, the inner size of the sleeve 305 is adapted to the outer size of the rotating shaft 303, so that the sleeve 305 can only be axially slidably adjusted on the rotating shaft 303, and the sleeve 305 and the rotating shaft 303 will not rotate relative to each other in the radial direction, thereby ensuring the stability of the grinding wheel 306 being driven to rotate at high speed. During the high-speed rotation of the rotating shaft 303, it will drive the sleeve 305 sleeved on its outer side to rotate synchronously, thereby driving the fixed installation The grinding wheel 306 on the sleeve 305 rotates synchronously at high speed to grind the cross-section of the columnar part. The thickness of the grinding wheel 306 is consistent with the thickness of the cutting wheel 304, so that the grinding wheel 306 can more stably and smoothly enter between two adjacent columnar parts for grinding processing. Since the sleeve 305 can slide axially along the rotating shaft 303, the staff can adjust the distance between the cutting wheel 304 and the grinding wheel 306 according to the length of the columnar part formed by the processing. After adjustment, it only needs to be tightened again with bolts. The operation is flexible and convenient, which improves the production applicability of the device to a certain extent.

[0026] In the specific implementation process, Figure 3 and Figure 6 - Figure 8As shown, the two first V-shaped blocks 308 located on the far left and the far right are fixedly connected to the outer frame 3, and the remaining first V-shaped blocks 308 are slidably connected to the bottom end wall of the outer frame 3. A transversely arranged first spring 309 is fixedly connected between two adjacent first V-shaped blocks 308, and a vertically arranged stud 310 is screwed on the first V-shaped block 308. When the device is in use, when the metal rod is inserted into the synchronous moving mechanism, it will be erected on the many first V-shaped blocks 308 installed in the middle position of the bottom end wall of the outer frame 3. Through the support of the many first V-shaped blocks 308, the stability of the horizontal leftward conveying of the metal rod and the columnar parts generated by cutting can be effectively guaranteed. At the same time, through the support of the many first V-shaped blocks 308, the stability of the metal rod cutting operation caused by the downward pressure of the cutting wheel 304 can be guaranteed. Among the many first V-shaped blocks 308, except for the two first V-shaped blocks 308 on the far left and the far right that are fixedly connected to the bottom end wall of the outer frame 3, The remaining first V-shaped blocks 308 can all be slid to fine-tune their positions. By adjusting the sliding of the first V-shaped blocks 308, the first V-shaped blocks 308 can be avoided from being directly below the grinding wheel 306, which is beneficial to ensuring the stability of the device during operation. Each slidable first V-shaped block 308 is threaded with a vertically arranged stud 310. After the stud 310 is rotated and moved, the movable first V-shaped block 308 can be fixedly connected to the bottom end wall of the outer frame 3. By fixing a first spring 309 between two adjacent first V-shaped blocks 308, when adjusting the numerous slidable first V-shaped blocks 308, the staff only needs to fix the two first V-shaped blocks 308 closest to the left and right sides below the grinding wheel 306. The remaining slidable first V-shaped blocks 308 can be adaptively and evenly distributed under the elastic connection of the first spring 309, which is beneficial to improving the operational flexibility of the device when adjusting the numerous first V-shaped blocks 308.

[0027] In the specific implementation process, Figure 4 , Figure 6 - Figure 7 and Fig. 9 As shown, the first chamfering mechanism includes a first slide 5 slidably installed on the left side of the top of the base 1, and a second electric clamp 501 is installed in the first slide 5, a first supporting frame 502 is arranged on the left side of the first slide 5, and a first grinding disc 503 is rotatably installed on the side of the first supporting frame 502 close to the first slide 5, and a conical groove is provided at the axial position of the first grinding disc 503 close to the first slide 5, a first through groove 505 is provided on the left side of the top of the base 1 below the first slide 5, a second connecting plate 6 is fixedly installed on the front end wall of the first slide 5, and a third electric push rod 601 is fixedly installed on the top of the base 1 and is transversely arranged on the right side of the second connecting plate 6, and the telescopic end of the third electric push rod 601 is connected to the second connecting plate 6.

[0028] When the device is in use, the numerous columnar parts formed by cutting at the left end of the metal rod are transported to the left in an orderly manner under the continuous leftward movement of the metal rod, and the columnar parts enter the first chamfering mechanism under continuous push, and then the second electric clamp 501 installed in the first slide 5 is powered on and started to clamp the columnar parts, so that the columnar parts are firmly connected to the first slide 5, accompanied by continuous pushing on the right side, so that the first slide 5 drives the first carrier 502 to move left synchronously, and the left end of the columnar part clamped in the second electric clamp 501 enters the conical groove on the right side of the first grinding disc 503 and contacts the inner end wall of the conical groove. At this time, the columnar part and the first grinding disc 503 are on the same central axis, and a servo motor is installed on the first carrier 502, which is used to drive the first grinding disc 503 to rotate at high speed. During the high-speed rotation of the first grinding disc 503, the edge position of the left cross-section of the columnar part is ground and chamfered, so that the columnar part completes the first grinding and chamfering.

[0029] During the process of the first slide 5 moving to the left, the third electric push rod 601 is powered on and started, and its telescopic end moves rapidly to the left, pushing the first slide 5 to move rapidly to the left, so that the speed of the first slide 5 moving to the left is greater than the conveying speed of the metal rod, thereby separating the columnar part clamped in the second electric clamp 501 from the unclamped columnar part on its right side. After the first grinding wheel 503 grinds and chamfers the left end of the columnar part, the second electric clamp 501 releases the clamping of the columnar part. Under the action of gravity, the columnar part that has completed the chamfering process once falls downward through the first through groove 505 into the second chamfering mechanism, ready for the second chamfering process. After the second electric clamp 501 releases the clamping of the columnar part, the telescopic end of the third electric push rod 601 moves in the opposite direction and resets, driving the first slide 5 to move rapidly to the right and reset, ready for grinding and chamfering the left end of the next columnar part.

[0030] In the specific implementation process, Figure 5 - Figure 7 and Fig. 9 - Fig.10As shown, the second chamfering mechanism includes a platform 7 fixedly mounted on the lower left side of the base 1, and a second slide 701 located directly below the first through slot 505 is slidably mounted on the platform 7, a third electric clamp 702 is mounted in the second slide 701, a V-shaped table 703 is fixedly mounted on the left side of the top of the platform 7, a support block 705 adapted to the V-shaped table 703 is mounted on the right side of the second slide 701, and a second bearing frame 706 is arranged on the right side of the support block 705, and a second grinding disc 707 is rotatably mounted on the side of the second bearing frame 706 close to the second slide 701, and A conical groove is provided at the axial position of the second grinding disc 707 near the second slide 701, and a second through groove 709 is provided on the platform 7 below the second slide 701. The bottom of the first slide 5 and the top of the second slide 701 are both arranged as through-type structures. A third connecting plate 602 vertically arranged on the right side of the second connecting plate 6 is fixedly installed on the front end wall of the second slide 701, and the third connecting plate 602 is fixedly connected to the telescopic end of the third electric push rod 601, and a magnet 603 that magnetically attracts the second connecting plate 6 is fixed on the third connecting plate 602.

[0031] When the device is used, the columnar part falls and enters the second chamfering mechanism. Due to the support of the V-shaped table 703 and the support block 705, the columnar part that falls can be in a horizontal and vertical state. Then the third electric clamp 702 installed in the second slide 701 is powered on to clamp the falling columnar part. During the reset process of the first slide 5 moving to the right by the third electric push rod 601, the second slide 701 will be driven to move to the right synchronously, thereby causing the columnar part clamped in the third electric clamp 702 in the second slide 701 to move to the right synchronously. The right end of the columnar part enters the conical groove opened on the left side of the second grinding disc 707. A servo motor is fixedly installed on the second supporting frame 706. The servo motor is used to drive the second grinding disc 707 to rotate at high speed to achieve grinding and chamfering of the edge position of the cross section of the right end of the columnar part. After the secondary chamfering is completed, the third electric clamp 702 releases the clamping of the columnar part. Under the action of gravity, the columnar part falls downward through the second through groove 709 and is exported. Then the third electric push rod 601 pushes the platform 7 to move to the left and reset, preparing to grind and chamfer the right end of the next columnar part.

[0032] In the specific implementation process, Figure 4 , Figure 5 and Figure 7As shown, the first carrier 502 is slidably connected to the base 1, a transversely arranged second spring 504 is fixedly connected between the first slide 5 and the first carrier 502, the second carrier 706 is slidably connected to the platform 7, and a transversely arranged third spring 708 is fixedly connected to the right side of the second carrier 706, and the right end of the third spring 708 is fixedly connected to the platform 7. When the device is in use, since the first carrier 502 is slidably connected to the base 1 and is fixedly connected to the first slide 5 through the second spring 504, the columnar part can be stably moved continuously to the left before being clamped by the second electric clamp 501, so that the conical groove opened on the first grinding disc 503 can adaptively fit tightly with the left end of the columnar part, which is beneficial to ensure the stability of the device when grinding and chamfering the left end of the columnar part.

[0033] At the same time, since the telescopic end of the third electric push rod 601 is directly fixedly connected to the third connecting plate 602 fixed on the second slide 701, and the second connecting plate 6 fixed on the first slide 5 is magnetically connected to the third connecting plate 602 through the magnet 603, when the telescopic end of the third electric push rod 601 moves to the left, it can synchronously push the first slide 5 and the second slide 701 to move to the left. When the telescopic end of the third electric push rod 601 moves to the right, it can drive the first slide 5 and the second slide 701 to move right synchronously for a period of time. When the first slide 5 moves to the right to the extreme position, the magnet 603 can be separated from the second connecting plate 6. At this time, the third electric push rod 601 can continue to drive the second slide 701 to move to the right, and cooperate with the third spring 708 to elastically support the second carrier frame 706, so that the right end of the columnar part clamped in the third electric clamp 702 can be more stably and tightly fitted with the conical groove opened on the second grinding disc 707, which is conducive to ensuring the stability of the device when grinding and chamfering the right end of the columnar part.

[0034] In the specific implementation process, Figure 7 As shown, a fourth electric push rod 704 pointing vertically upward is fixedly installed on the right side of the second slide 701, and a support block 705 is fixedly installed on the telescopic end of the fourth electric push rod 704. When the device is in use, after the third electric clamp 702 releases the clamping of the columnar part, in order to ensure that the columnar part can fall smoothly, the telescopic end of the fourth electric push rod 704 installed on the right side of the second slide 701 will extend upward, driving the support block 705 to move upward, driving the columnar part to be in a tilted state, so as to facilitate the smoothness and stability of the falling and discharging of the columnar part after grinding and chamfering.

[0035] In the specific implementation process, Figure 1 , Figure 6 and Figure 7As shown, a plurality of evenly distributed second V-shaped blocks 8 are installed at the top middle position of the base 1, and the plurality of second V-shaped blocks 8 are distributed from right to left between the outer frame 3 and the first slide 5. The second V-shaped block 8 on the leftmost side is fixedly connected to the base 1, and the remaining second V-shaped blocks 8 are slidably connected to the base 1. A transversely arranged fourth spring 801 is fixedly connected between two adjacent second V-shaped blocks 8. When the device is used, the plurality of columnar parts formed by cutting the metal rod can be smoothly transferred from the synchronous moving mechanism to the first chamfering mechanism through the support of the plurality of evenly distributed second V-shaped blocks 8. Among the numerous second V-shaped blocks 8, except for the leftmost second V-shaped block 8 fixedly connected to the base 1, the remaining second V-shaped blocks 8 are all slidably connected to the base 1, and two adjacent second V-shaped blocks 8 are elastically connected via a fourth spring 801, so that when the outer frame 3 moves to the left, the numerous slidable second V-shaped blocks 8 can slide to the left due to the leftward squeezing of the outer frame 3; when the outer frame 3 moves to the right to reset, the numerous second V-shaped blocks 8 move to the right and unfold again with the elastic support of the fourth spring 801, thereby realizing adaptive lifting of the columnar parts, which is beneficial to ensuring the stability of the device during operation.

[0036] Specifically, the working principle and operation method of the present invention are as follows: The metal rod is continuously and stably conveyed to the left under the synchronous relative rotation of the two gears 201. The metal rod enters the synchronous moving mechanism. After reaching the predetermined position, the first electric clamp 301 starts to clamp the metal rod to maintain the firm connection between the outer frame 3 and the metal rod, so that the synchronous moving mechanism can move to the left synchronously with the metal rod. During the synchronous movement, the lifting platform 302 drives the high-speed rotating cutting wheel 304 and the grinding wheel 306 to move downward. The cutting wheel 304 moves downward to cut the metal rod into columnar parts. The grinding wheel 306 moves downward to enter between the two ends of two adjacent columnar parts to grind and polish the cross-section of the end of the columnar parts. After a single cutting and grinding is completed, the first electric clamp 301 releases the clamping of the metal rod. Driven by the second electric push rod 401, the outer frame 3 quickly moves right and resets to prepare for the next cutting and grinding operation. After cutting and grinding, the numerous columnar parts move to the left along the central axis of the metal rod. Under the support of the numerous second V-shaped blocks 8, the columnar parts enter the first chamfering mechanism. Under continuous pushing, the left end of the leftmost columnar part is tightly fitted with the conical groove opened on the right side of the first grinding disc 503. Synchronously, the second electric clamp 501 is powered on to clamp the columnar part, and the third electric push rod 601 is powered on to drive the first slide 5 to drive the clamped columnar part to move quickly to the left, so that it is separated from the adjacent columnar part on the right. In this process, the first grinding disc 503 rotates at a high speed to complete the chamfering of the edge position of the cut surface of the left end of the clamped columnar part, and then the second electric clamp 501 releases the clamping of the columnar part. Under the action of gravity, the columnar part after one chamfer passes through the first through groove 505 and falls into the second chamfering mechanism. The first slide 5 is driven by the third electric push rod 601 to move right and reset, ready to chamfer the left end of the next columnar part. Under the support of the V-shaped table 703 and the support block 705 entering the second chamfering mechanism, it is clamped by the third electric clamp 702 in a horizontal posture. When the third electric push rod 601 drives the first slide 5 to move right and reset, the columnar part clamped by the third electric clamp 702 is driven to move right synchronously, and the right end of the columnar part is tightly fitted with the conical groove opened on the second grinding disc 707. With the help of the high-speed rotation of the second grinding disc 707, the chamfering of the right end of the columnar part is completed, and then the third electric clamp 702 releases the clamping of the columnar part, and with the help of the fourth electric push rod 704, the support block 705 is driven to move upward, so that the right end of the columnar part is tilted upward, which is convenient for the columnar part after the secondary chamfering to fall and be exported through the second through groove 709 more smoothly, and then the platform 7 is driven by the third electric push rod 601 to reset to the left, ready to chamfer the right end of the next columnar part.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
