Description

Technical Field

[0001] The invention belongs to the technical field of barrel processing, and in particular, relates to a barrel processing device. Background Art

[0002] For the processing of the inner holes at both ends of the cylindrical parts, the original processing method is to use hydraulic three-claw clamping at one end, place a core tire in the inner hole, use a nylon open jacket on the outer edge, and use a combination of an aluminum alloy ring sleeve and a nylon cone ring at the other end to put the ring on the outer circle of the part. During the processing, the center frame is used to support the outer circle of the circle to process the end face, inner hole shape and thread of the part. After one end is processed, turn around and process the shape, thread and total length of the other end.

[0003] However, this method has many disadvantages: first, the turning process requires the parts to be clamped twice, which not only increases the labor intensity and prolongs the processing cycle, but also affects the processing accuracy of both ends of the product; second, since there is an error of about 2mm in the diameter of the cylinder, the clamping tightness is inconsistent, which can easily cause the parts to vibrate during processing, and then produce vibration marks, affecting the processing accuracy; third, the inconsistency of the wall thickness of the parts also aggravates the instability of the shape and size; finally, the overall processing process is cumbersome, which reduces production efficiency and yield rate.

[0004] In view of this, there is an urgent need for a new barrel processing device that can improve processing accuracy and stability by optimizing the clamping method, reduce vibration and errors during processing, improve product quality, and at the same time significantly shorten the processing cycle, reduce labor intensity, and improve production efficiency.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings.

[0033] like Figure 1-Figure 7As shown, this embodiment provides a barrel processing device, including a frame 1, a clamping mechanism 2, a processing mechanism 3, a blower mechanism 4 and an air suction mechanism 5. The clamping mechanism 2 is arranged on the frame 1, and the barrel to be processed is installed in the middle of the clamping mechanism 2. The processing mechanism 3 is arranged on the frame 1 and can move bidirectionally on the frame 1. The blower mechanism 4 and the air suction mechanism 5 are both connected to the frame 1 and the clamping mechanism 2. After the barrel is clamped from the inside by the clamping mechanism 2, the air suction mechanism 5 cooperates with the frame 1 and the clamping mechanism 2 to further fix the barrel by sucking away the air between the clamping mechanism 2 and the part fitting surface. The processing mechanism 3 slides on the frame 1 to process both ends of the barrel. During this period, the blower mechanism 4 cooperates with the frame 1 and the clamping mechanism 2 to blow the debris and dust generated during the processing away from the processing surface in time to avoid obstruction to the processing and affect the processing accuracy.

[0034] The rack 1 is used as a supporting structure, mainly for carrying other components, such as Figure 1 and Figure 2 As shown, the frame 1 includes a mounting frame 11, a lathe body 12, two vent frames 13, two vent annular columns 14, two groups of brackets 15 and a combination box 16. The mounting frame 11 is fixedly connected to both ends of the lathe body 12, one of the vent frames 13 is fixedly connected to one side of the lathe body 12, and the other vent frame 13 is slidably arranged on the other side of the lathe body 12. The two vent frames 13 are perpendicular to the lathe body 12, and each vent frame 13 is provided with a cylindrical hole. The vent annular column 14 is rotatably arranged in the above-mentioned cylindrical hole and is sealed with the vent frame 13. The two vent annular columns 14 are fixedly connected to the clamping mechanism 2 through the corresponding brackets 15 respectively, so that the vent annular column 14 moves with the clamping mechanism 2, wherein the cylindrical hole, the vent annular column 14 and the clamping mechanism 2 are coaxial. The mounting frame 11 and the lathe body 12 are used to carry other components, and the ventilation hole frame 13 and the ventilation annular column 14 together constitute an air flow channel system, which converts static ventilation into dynamic ventilation to assist in realizing the functions of the blowing mechanism 4 and the suction mechanism 5.

[0035] Specifically, Figure 3As shown, each vent frame 13 is provided with a circle of first air suction grooves 131 and a circle of first blowing grooves 132 on the side of its cylindrical hole, the first air suction grooves 131 are located on the side of the cylindrical hole away from the part, and the first blowing grooves 132 are located on the side of the cylindrical hole close to the part, and each ventilation annular column 14 is also provided with a circle of second air suction grooves 141 and a circle of second blowing grooves 142. When the vent frame 13 is tightly matched with the ventilation annular column 14, the first air suction grooves 131 and the second air suction grooves 141 are tightly matched, and the first blowing grooves 132 are located on the side of the cylindrical hole close to the part. The groove 132 is closely matched with the second blowing groove 142. Two holes are provided on the top of the vent frame 13, which are connected with the first suction groove 131 and the first blowing groove 132 respectively. Three holes are evenly provided on both sides of the ventilation annular column 14, of which the three holes on one side close to the part are connected with the second blowing groove 142, and the three holes on the other side are connected with the second suction groove 141. The external airflow is introduced from the vent frame 13, and can be drawn out from the ventilation annular column 14 through the cooperation of the vent frame 13 and the ventilation annular column 14, and vice versa. Through the ingenious cooperation and slot design of the vent frame 13 and the ventilation annular column 14, the external airflow is introduced through the vent frame 13 and distributed to the suction groove or the blowing groove according to demand. The ventilation annular column 14 rotates with the clamping mechanism 2, changing the relative position between the slot and the hole, and realizing dynamic adjustment of the airflow path.

[0036] The clamping mechanism 2 is used to firmly clamp the parts from the inside to avoid errors and deformations during processing. Specifically, Figure 1As shown, the clamping mechanism 2 includes a hydraulic chuck 21, a first extended claw 22, a rotating member 23, a three-claw cylinder 24, a second extended claw 25, two inner support members 26, a tailstock 27 and a first telescopic cylinder 28. The hydraulic chuck 21 is mounted at one end of the lathe body 12 and is driven to move by a driving device inside the lathe body 12. This is a prior art of the lathe and will not be described here. The first extended claw 22 and the second extended claw 25 are both composed of three identical extended members. The three extension pieces of the first extension claw 22 are fixedly connected to the claws of the hydraulic chuck 21, and the cylinder is clamped from the inside with the movement of the hydraulic chuck 21. The first telescopic cylinder 28 is fixedly installed on the side of the lathe body 12 away from the hydraulic chuck 21, and is fixedly connected to one side of the lower end of the tailstock 27. The other side of the lower end of the tailstock 27 is fixedly connected to the sliding vent frame 13, so that the vent frame 13 slides on the lathe body 12 with the tailstock 27, and one end of the rotating member 23 The tailstock 27 is rotatably connected to the side of the part facing the tailstock 27, and a driving device is arranged inside the tailstock 27. The driving device is used to drive the rotating member 23 to rotate, including but not limited to a driving motor. A three-claw cylinder 24 is fixedly installed on the other end of the rotating member 23. The three extensions of the second extension claw 25 are fixedly connected to the clamping claws of the three-claw cylinder 24. The cylinder body is clamped from the inside with the movement of the three-claw cylinder 24. A bearing is used in the middle of the rotating member 23 to realize axial rotation. The inner support member 26 is annular as a whole and can be equally divided into three completely identical arc segments. The outer diameters of the extensions of the first extension claw 22 and the second extension claw 25 match the inner diameters of the corresponding arc segments and are connected together, so that the two inner support members 26 are respectively installed on the first extension claw 22 and the second extension claw 25. The outer circle of the inner support member 26 is processed according to the inner hole size of the standard part, and the ring width is designed according to the size of the processing mechanism 3 and the distance of the thread turning back. In this embodiment, the inner support member 26 is made of nylon material. Among them, the hydraulic chuck 21 cooperates with the first extended jaw 22, and the three-jaw cylinder 24 cooperates with the second extended jaw 25 to achieve clamping of the two ends of the part from the inside to the outside. The tail stock 27 is pushed by the first telescopic cylinder 28 to determine the processing depth of the cylindrical part and install the part. The hydraulic chuck 21 and the rotating part 23 rotate synchronously, driving the clamping mechanism 2 to rotate, and then driving the processed part to rotate. With the cooperation of the processing mechanism 3, the thread processing of the inner holes at both ends of the part can be achieved. The internal support member 26 clamps the part by internally supporting and tightening the part. This avoids the interference caused by the original clamping method (the clamping method described in the background technology) during the processing, and the part must be processed twice. At the same time, the stability of the part during the processing is improved, the clamping of parts with different outer diameters is met, the processing error caused by the wall thickness error of the part is reduced, and the processing accuracy and the stability of the processing shape and size of the part are improved.

[0037] The processing mechanism 3 is used to process both ends of the part, specifically, Figure 1 and Figure 2 As shown, the processing mechanism 3 includes a tool holder 31, a second telescopic cylinder 32, a heightening member 33, a third telescopic cylinder 34, a tool head assembly 35 and a first motor 36, wherein the tool holder 31 is an F-shaped structure, which is placed horizontally on one side of the lathe body 12, the second telescopic cylinder 32 is fixedly mounted on the end of the mounting frame 11 close to the tailstock 27, the tool holder 31 is fixedly connected to the second telescopic cylinder 32, the heightening member 33 and the third telescopic cylinder 34 are respectively arranged on the tool holder 31, the heightening member 33 and the third telescopic cylinder 34 are connected, the heightening member 33 slides longitudinally on the tool holder 31 under the pull of the third telescopic cylinder 34, a square space is opened on the heightening member 33, the first motor 36 is placed in the above-mentioned square space, the output shaft of the first motor 36 is fixedly connected to the tool head assembly 35, the tool head assembly 35 is controlled to rotate, and the left and right ends of the cylinder can be processed. The tool holder 31 serves as the basic support member of the processing mechanism 3, and is used to drive the processing mechanism 3 to move back and forth along one side of the lathe body 12. The heightening member 33 is used to increase the tool head assembly 35 to a processing height. The above-mentioned processing height is the starting position of the processing, which is the height of the part axis in this embodiment. In addition, the heightening member 33 can also drive the tool head assembly 35 to slide in a direction perpendicular to the part, so that the tool head assembly 35 can be aligned with the processing position, and the tool head assembly 35 can rotate axially. At the same time, it can move in two directions driven by the tool holder 31 and the heightening member 33, so that both ends of the part can be processed, avoiding manual re-clamping of the parts and improving the processing efficiency.

[0038] Specifically, during the barrel processing, both ends of the barrel need to be processed, and there may be multiple processing requirements at both ends of the barrel. In order to avoid manual tool change resulting in reduced efficiency and loss of precision, such as Figure 4 As shown, the cutter head assembly 35 includes a first cutter head 351, a second cutter head 352, a rotating tool holder 353, a second motor 354 and a cutter holder 355, wherein one end of the cutter holder 355 is fixedly mounted on the output shaft of the first motor 36, and the other end is provided with an opening, and the rotating tool holder 353 is placed in the above opening. In the present embodiment, two cutter heads are provided, the first cutter head 351 and the second cutter head 352, and the two cutter heads are fixedly connected to the outer edge of the rotating tool holder 353. It should be noted that the number and type of cutter heads are determined according to the processing requirements and are not limited to two types. A space is provided at the lower position of the cutter holder 355 corresponding to the rotating tool holder 353 for placing the second motor 354. The rotating tool holder 353 is fixedly connected to the output shaft of the second motor 354 to realize the replacement of the first cutter head 351 and the second cutter head 352.

[0039] Specifically, Figure 1-Figure 3 , Figure 5-Figure 7As shown, the hair blowing mechanism 4 includes a hair dryer 41, a first hair dryer hose 42, a second hair dryer hose 43, an air nozzle 44 and an air groove 45, and the air suction mechanism 5 includes an air pump 51, a first air suction hose 52, a second air suction hose 53, a circular hole 54 and an air groove 55, wherein the hair dryer 41 and the air pump 51 are both arranged in the combination box 16. In this embodiment, the hair dryer 41 is fixedly connected to the bottom of the combination box 16, and the air pump 51 is arranged on the hair dryer 41. Since both ends of the cylinder need to be processed, in addition to the hair dryer 41 and the air pump 51, the hair blowing mechanism 4 and the air suction mechanism 5 need to be arranged in two corresponding groups.

[0040] Specifically, Figure 1 As shown, both ends of the hair dryer 41 and the air pump 51 are connected with hoses for ventilation. Both ends of the hair dryer 41 are first blowing hoses 42, and both ends of the air pump 51 are first suction hoses 52. The first blowing hose 42 and the first suction hose 52 are respectively connected with two holes opened on the top of the ventilation hole frame 13, so that the first blowing hose 42 and the first blowing slot 132 can achieve airflow communication, and the first suction hose 52 and the first suction slot 131 can achieve airflow communication.

[0041] like Figure 2-Figure 3 , Figure 5-Figure 7As shown, three second blowing hoses 43 and second suction hoses 53 are provided in each group, and one end of the second blowing hose 43 is connected to three holes opened on one side of the ventilation annular column 14 close to the part, so that the second blowing hose 43 and the second blowing slot 142 can achieve airflow communication, and three groups of air nozzles 44 are evenly distributed on one side of the three arc segments of the inner support member 26 close to the tube mouth, and each group of air nozzles 44 is provided with a plurality of them, and are connected to the air slot 45 opened inside the corresponding arc segment, and the three extension pieces of the first extension claw 22 and the three matching ones are connected. The three arc segments cooperate to open three blowing channels that are connected, and the three extension pieces of the second extension claw 25 and the three arc segments that cooperate therewith cooperate to open three blowing channels that are connected, and the other end of the second blowing hose 43 passes through the corresponding blowing channels and is connected to the corresponding wind slot 45, so that the airflow in the blower 41 passes through the first blowing hose 42, the first blowing slot 132, the second blowing slot 142, the second blowing hose 43 and the wind slot 45 in sequence, and is discharged by the air nozzle 44, so as to blow away the debris during processing. Open, improve the processing accuracy; one end of the three second air suction hoses 53 is connected to the three holes opened on the side of the ventilation annular column 14 away from the parts, so that the second air suction hose 53 and the second air suction groove 141 can achieve airflow communication, and three groups of circular holes 54 are evenly distributed on the outer edges of the three arc segments of the inner support member 26, each group of circular holes 54 is provided with a plurality of holes, and are connected to the air groove 55 opened inside the corresponding arc segment, and three through-going air suction channels are opened in the three extension members of the first extension claw 22 and the three arc segments matched therewith. Three through-going air suction channels are formed in the three extension pieces of the second extension claw 25 and the three arc segments matched therewith. The other end of the second air suction hose 53 passes through the corresponding air suction channel and is connected with the corresponding air groove 55. Thus, the air flow passes through the circular hole 54, the air groove 55, the second air suction hose 53, the second air suction groove 141, the first air suction groove 131 and the first air suction hose 52 in sequence, and is sucked away by the air pump 51. The inner support member 26 is reinforced by suction to prevent the parts from vibrating and generating vibration marks during processing.

[0042] The above is a barrel processing device provided by this embodiment, and its principle is:

[0043] Preparation work: install the two inner support members 26 on the first extended claw 22 and the second extended claw 25, check whether the vent frame 13 and the ventilation annular column 14 are tightly matched, and check whether the air circuit connection between the blower mechanism 4 and the suction mechanism 5 is correct. Place the processing mechanism 3 in the initial position, that is: the second telescopic cylinder 32 pulls the tool holder 31 to the rightmost side of the frame 1, and the third telescopic cylinder 34 pulls the heightening member 33, so that the tool head assembly 35 is away from the clamping mechanism 2 and rotated to a direction perpendicular to the part to be processed. Move the tooling at one end of the tailstock 27 to the vicinity of the hydraulic chuck 21, clamp a coaxial rod in the middle, and check whether the inner support tooling at both ends is coaxial.

[0044] After the preparation is completed, the positioning position of the cylinder clamping is set according to the shape, length and position of the inner hole that needs to be processed at both ends of the cylinder. The cylinder part to be processed is placed between the first extended claw 22 and the second extended claw 25, ensuring that the axis of the part is aligned with the center of the device, the hydraulic chuck 21 is started, and one end of the part is clamped by the first extended claw 22, the first telescopic cylinder 28 is started to push the tailstock 27 to slide, the position of the second extended claw 25 is adjusted, the processing depth is determined, and the three-claw cylinder 24 is started to clamp the other end of the part by the second extended claw 25. In this process, the inside of the part is tightened by the nylon inner support 26 to enhance the stability of the clamping, and the air pump 51 is started for suction, and the air between the inner support 26 and the part fitting surface is sucked away by the first suction hose 52 and the second suction hose 53 to generate negative pressure, thereby enhancing the stability of the clamping.

[0045] Before processing, Figure 2 As shown, the second telescopic cylinder 32 pushes the tool holder 31, so that the processing mechanism 3 moves to the end to be processed. In this embodiment, the left barrel mouth is processed first, and the cutter head assembly 35 is axially rotated counterclockwise to be parallel to the part. The third telescopic cylinder 34 pushes the heightening member 33 to move, so that the cutter head assembly 35 moves toward the part. Through the above principle, the position of the cutter head assembly 35 is adjusted so that the cutter head assembly 35 is aligned with the processing position of the part. Further, as shown in FIG. Figure 4 As shown, the first motor 36 is started, and the rotary tool holder 353 rotates so that the first tool head 351 is aligned with the processing position. In this embodiment, the first tool head 351 is used for processing threads.

[0046] After the processing starts, the blower mechanism 4 is started, the blower tube 41 works, the air flow is guided by the first blow hose 42 and the second blow hose 43, flows into the air groove 45, and is finally blown out evenly by the air nozzle 44. The driving device in the lathe body 12 and the driving device in the tailstock 27 drive the hydraulic chuck 21 and the rotating part 23 to rotate synchronously, thereby driving the processed cylinder to rotate. At the same time, the second telescopic cylinder 32 pushes the tool holder 31 to slide, so that the first tool head 351 can realize thread processing on the inner wall of the cylinder.

[0047] After completing the thread processing, start the first motor 36, and the rotating tool holder 353 rotates so that the second cutter head 352 is aligned with the processing position. In this embodiment, the second cutter head 352 is used to process the barrel mouth. The driving device in the lathe body 12 and the driving device in the tailstock 27 drive the hydraulic chuck 21 and the rotating part 23 to rotate synchronously, thereby driving the processed barrel to rotate. At the same time, the third telescopic cylinder 34 pushes the raising part 33 to slide to complete the barrel mouth processing.

[0048] After completing the processing of the left side of the barrel, the second telescopic cylinder 32 pulls the tool holder 31 to slide to the right side of the barrel, and rotates the tool head assembly 35 axially clockwise to be parallel to the part to process the right side thread and barrel. The specific steps are the same as the left side.

[0049] After all processing is completed, turn off the blower 41 and the air pump 51, turn off the hydraulic chuck 21 and the three-jaw cylinder 24, release the clamping of the parts, use the first telescopic cylinder 28 to return the tailstock 27 to its original position, remove the processed barrel, and complete all processing steps.

[0050] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention.
