Description

Technical Field

[0001] This invention relates to the field of workpiece processing technology, and specifically to a milling and chamfering machine. Background Technology

[0002] The milling and chamfering machine is an automated device widely used in the field of machining. Its main function is to complete two key processes on the workpiece: milling grooves and chamfering the edges. In a typical application scenario, the processing object is a hollow tubular blank. The processing flow is usually as follows: First, the hollow blank is firmly fixed by a special fixture. Then, the fixture moves the blank along a predetermined path to the milling station. The high-speed rotating milling cutter completes the milling of cross-shaped grooves on the tube wall. After the milling is completed, the fixture continues to move the workpiece to the chamfering station, where the chamfering cutter chamfers the ends of the blank or the edges of the grooves.

[0003] While the integrated milling and chamfering machining method described above is widely used, in actual production, chamfering cutters are usually designed to be relatively long to ensure machining range and rigidity. These cutters are typically mounted by directly fixing their shank to the output shaft of the drive motor via a connecting flange. This leaves the chamfering cutter in a cantilevered state during machining. During prolonged continuous chamfering operations on a workpiece, the suspended chamfering cutter continuously bears the cutting reaction force from the workpiece. As working time accumulates, the cutter and its connecting components will experience slight vibrations and offsets due to material fatigue and stress deformation. This offset is directly transmitted to the machined surface, causing the chamfered dimensions to gradually deviate from the design standards, severely affecting product consistency and machining accuracy. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a milling and chamfering machine that effectively solves the problem that in existing technologies, during long-term continuous chamfering operations on blanks, the suspended chamfering cutter continuously bears the cutting reaction force from the workpiece. As the working time accumulates, the cutter and its connecting parts will experience slight vibrations and offsets due to material fatigue and stress deformation. This offset will be directly transmitted to the machined surface, causing the chamfered dimensions of subsequent machining to gradually deviate from the design standards, seriously affecting product consistency and machining accuracy.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a milling and chamfering machine, comprising: The base has slide rails on it in the left and right directions, and a limiting fixture for clamping and fixing the blank is slidably mounted on the slide rails. A milling machine unit is set on a base and located on the moving path of a limiting fixture. The milling machine unit includes two supports symmetrically arranged according to the slide rail, and each support is equipped with two sets of cutters in different directions. The chamfering unit has two units, which are symmetrically arranged according to the slide rail. The chamfering unit includes a support base fixedly mounted on a base, a slide table mounted on the support base, and an execution component mounted on the slide table to perform chamfering work on the blank material; The actuator includes a motor and a chamfering cutter mounted on the output shaft of the motor via a connecting sleeve. The top of the chamfering cutter is machined into a conical shape. A support frame is fixedly mounted on the support base, and an adjustment component is provided on the support frame to support the chamfering cutter during the machining process.

[0006] Furthermore, a motor base is slidably mounted on the slide table, the motor is located inside the motor base, and an arc-shaped groove is provided on the support frame corresponding to the position of the motor, and a support member is provided on the side of the support frame near the slide rail.

[0007] Furthermore, the support includes a base frame fixedly mounted on the support bracket, a mounting collar fixedly mounted at the top of the base frame, and a mounting plate fixedly mounted on the side of the base frame near the slide rail.

[0008] Furthermore, a sliding groove is provided on the mounting plate along the front-back direction, and a sliding rod extending in the front-back direction is fixedly installed inside the sliding groove. An adjusting seat connected to the inner wall of the sliding groove is slidably sleeved on the outer circumference of the sliding rod through a top pressure spring. A telescopic plate is provided on the connecting sleeve, and the telescopic plate slides through the mounting plate and is connected to the adjusting seat.

[0009] Furthermore, the adjusting component includes an adjusting collar that is fixedly connected to the mounting collar and sleeved on the outer circumference of the chamfering cutter. The inner circumference of the adjusting collar is provided with several receiving grooves along the front-back direction. Each receiving groove is provided with several balls that are rolled and connected to the outer circumference of the chamfering cutter along the circumference direction.

[0010] Furthermore, the outer circumferential wall of the adjusting collar is provided with a clearance groove, and a cleaning scraper is provided inside the clearance groove through a torsion spring. In the initial state, the cleaning scraper is in close contact with the inclined surface of the chamfering knife.

[0011] Furthermore, a guide groove is provided on the side wall of the cleaning scraper away from the chamfering blade, and a linkage block is fixedly installed inside the guide groove.

[0012] Furthermore, the adjusting seat and the linkage block are connected by a hinge plate, that is, the two ends of the hinge plate are rotatably connected to the linkage block and the adjusting seat respectively.

[0013] The technical solution provided by this invention has the following advantages compared with the prior art: Before the chamfering cutter operates, it first passes through an adjusting ring. Several ball bearings are mounted on the material-bearing ring inside the adjusting ring, supporting the cutter shank. When the chamfering cutter processes the workpiece, the cutting reaction force from the workpiece attempts to cause vibration and displacement of the cantilevered cutter. However, the shank is stably supported by the ball bearings inside the adjusting ring, greatly enhancing the radial rigidity of the cutter. This rolling support design fundamentally solves the problem of minor vibration and displacement caused by fatigue in cantilevered cutters. It is equivalent to adding a stable, low-friction auxiliary support point to the free end of the chamfering cutter, effectively suppressing chatter during long-term continuous operation, thus ensuring that the machined chamfer dimensions always conform to the design standards.

[0018] The present invention will be further described below with reference to embodiments. Example

[0019] Please see Figure 1 - Figure 10 The present invention provides a technical solution: a milling and chamfering machine, comprising: The base 1 has a slide rail 11 on it along the left and right directions, and a limiting clamp 2 for clamping and fixing the blank 100 is slidably arranged on the slide rail 11. The milling machine unit 3 is set on the base 1 and located on the moving path of the limiting fixture 2. The milling machine unit 3 includes two supports 31 symmetrically arranged according to the slide rail 11. Each support 31 is provided with two sets of cutters 32 in different directions. Chamfering unit 4, there are two chamfering units 4 and they are symmetrically arranged according to slide rail 11; The chamfering unit 4 includes a support base 41 fixedly mounted on the base 1, a slide table 42 mounted on the support base 41, and an execution component 43 mounted on the slide table 42 to perform chamfering work on the blank 100. The execution component 43 includes a motor 431 and a chamfering cutter 432 mounted on the output shaft of the motor 431 via a connecting sleeve 433. The top of the chamfering cutter 432 is machined into a conical shape. A support frame 434 is fixedly mounted on the support base 41. An adjustment component 435 is mounted on the support frame 434 to support the chamfering cutter 432 during the machining process.

[0020] A motor base 421 is slidably mounted on the slide table 42, and a motor 431 is mounted inside the motor base 421. An arc-shaped groove 4341 is provided on the support frame 434 corresponding to the position of the motor 431, and a support member 436 is provided on the side of the support frame 434 near the slide rail 11.

[0021] The support member 436 includes a base frame 4361 fixedly mounted on the support frame 434. A mounting collar 4362 is fixedly mounted on the top of the base frame 4361. A mounting plate 4363 is also fixedly mounted on the side of the base frame 4361 near the slide rail 11.

[0022] The mounting plate 4363 has a sliding groove 4364 along the front-back direction. A sliding rod 4365 extending in the front-back direction is fixedly installed inside the sliding groove 4364. An adjusting seat 4366 is slidably sleeved on the outer circumference of the sliding rod 4365 and connected to the inner wall of the sliding groove 4364 through a top pressure spring 4367. A telescopic plate 4368 is provided on the connecting sleeve 433. The telescopic plate 4368 slides through the mounting plate 4363 and is connected to the adjusting seat 4366.

[0023] The adjusting member 435 includes an adjusting collar 4351 that is fixedly connected to the mounting collar 4362 and sleeved on the outer circumference of the chamfering cutter 432. The inner circumference of the adjusting collar 4351 is provided with a number of receiving grooves along the front-back direction. Each receiving groove is provided with a number of balls 4352 that are rollingly connected to the outer circumference of the chamfering cutter 432 along the circumferential direction.

[0024] The outer circumferential wall of the adjusting collar 4351 is provided with a relief groove 4353. A cleaning scraper 4354 is provided inside the relief groove 4353 through a torsion spring. In the initial state, the cleaning scraper 4354 is in close contact with the inclined surface of the chamfering blade 432.

[0025] A guide groove 4355 is provided on the side wall of the cleaning scraper 4354 away from the chamfering blade 432, and a linkage block 4356 is fixedly installed inside the guide groove 4355.

[0026] The adjusting seat 4366 and the linkage block 4356 are connected by a hinge plate 437, that is, the two ends of the hinge plate 437 are rotatably connected to the linkage block 4356 and the adjusting seat 4366 respectively.

[0027] In specific work: In actual production, the chamfering cutter 432 is usually designed to be relatively long to ensure processing range and rigidity. The common installation method for this type of cutter is to directly fix its shank to the output shaft of the drive motor 431 via a connecting flange. This leaves the chamfering cutter 432 in a cantilevered state during processing. During prolonged continuous chamfering of the blank 100, the suspended chamfering cutter 432 continuously bears the cutting reaction force from the workpiece. With accumulated working time, the cutter and its connecting components will experience slight vibrations and offsets due to material fatigue and stress deformation. These offsets are directly transmitted to the processed surface, causing the chamfered dimensions to gradually deviate from the design standards, seriously affecting product consistency and processing accuracy. Therefore, the milling and chamfering machine's support frame 434 is equipped with an adjusting component 435. During operation, the adjusting component 435 supports the chamfering cutter 432 shank, preventing slight vibrations during operation.

[0028] Specifically, before the work begins, the chamfering cutter 432 is installed on the output shaft of the motor 431 via the connecting sleeve 433. During installation, the chamfering cutter 432 first passes through the adjusting sleeve 4351 set on the mounting sleeve 4362 (both the adjusting sleeve 4351 and the mounting sleeve 4362 are concentric with the output shaft of the motor 431. The inner circumference of the adjusting sleeve 4351 is provided with a receiving groove, and a material-bearing ring is fixedly set in the receiving groove. Several balls 4352 are rotatably set on the inner circumference of the material-bearing ring. During the installation of the chamfering cutter 432, the sliding friction is changed to rolling friction by the several balls 4352, thereby reducing the resistance of the chamfering cutter 432 during the installation process). After installation, the milling and chamfering work on the blank 100 is realized.

[0029] Two symmetrically arranged supports 31 are provided on the base 1, and each support 31 is equipped with a tool set 32 ​​(each tool set 32 ​​includes two milling cutters symmetrically arranged with respect to the limiting clamp 2, but the milling cutters of different sets are arranged in different directions, that is, the two tool sets 32 adopt a transverse and a longitudinal arrangement). After the blank 100 is limited, the limiting clamp 2 drives the blank 100 to move along the slide rail 11 to the position of the milling cutter. The milling cutters in different directions are used to mill the grooves at both ends of the blank 100. Then, the limiting clamp 2 drives the blank 100 to continue moving to the position of the chamfering cutter 432. The chamfering cutters 432 on both sides are used to chamfer the ends of the blank 100. The base 1 is provided with a support seat 41 and a slide table 42. The motor 431 and the chamfering sleeve are mounted on the slide table 42 via the motor seat 421. In the initial state, the chamfering cutters 432 on both sides are far apart. As the blank 100 moves to the chamfering station, the motor seats 421 on both sides synchronously drive the corresponding chamfering cutters 432 to move closer. Since the chamfering cutter 432 is always located inside the adjusting collar 4351, the chamfering cutter 432 is supported by the adjusting collar 4351 and the mounting collar 4362 during the operation of the chamfering cutter 432. This prevents the suspended chamfering cutter 432 from vibrating or slightly shifting due to force, thus laying the foundation for the consistency of the blank 100 processing.

[0030] In the batch and continuous chamfering process of blank 100, the high-speed friction between the chamfering cutter 432 and the workpiece generates a large amount of heat, causing the tool surface temperature to rise sharply. This results in fine metal chips adhering to the cutting edge of the chamfering cutter 432. As the working time continues, this layer of metal chips alters the original geometry and cutting edge shape of the chamfering cutter 432. When the irregularly shaped chamfering cutter 432 continues to process the blank 100, the actual chamfer width, depth, and angle will deviate significantly from the design values. This is because the accumulation of metal chips is a gradual and continuous process. The problem of controllable process is often only discovered after a considerable number of workpieces have been processed, which can easily lead to batch dimensional abnormalities in the entire batch of products. Based on this, the adjusting collar 4351 of the milling and chamfering machine is provided with a clearance groove 4353, and a cleaning scraper 4354 is provided inside the clearance groove 4353 through a torsion spring. In the initial state, when the blank 100 has not yet moved to the chamfering station, the cleaning scraper 4354 is in close contact with the processing surface of the chamfering cutter 432. The continuous rotation of the chamfering cutter 432 driven by the motor 431 causes the cleaning scraper 4354 to remove the metal chips adhering to the processing surface of the chamfering cutter 432.

[0031] Specifically, the mounting plate 4363 has a sliding groove 4364, and an adjusting seat 4366 is slidably disposed inside the sliding groove 4364 and connected to the inner wall of the sliding groove 4364 via a top pressure spring 4367. The adjusting seat 4366 is connected to the connecting sleeve 433 via a telescopic plate 4368. In the initial state, due to the force of the torsion spring, the cleaning scraper 4354 is in an inclined state. A hinge plate 437 is hinged between the linkage block 4356 and the adjusting seat 4366, which can effectively avoid... The problem of weakening spring force after long-term operation is addressed by the fact that when the motor base 421 has not moved, the telescopic plate 4368 is in its natural state. It will pull the hinge plate 437 through the adjusting seat 4366, thereby applying an upward force to the cleaning scraper 4354 through the hinge plate 437. This ensures that the cleaning scraper 4354 can always be in close contact with the working surface of the chamfering blade 432, and avoids the problem of the cleaning scraper 4354 being bounced off by the force from metal shavings during the cleaning process.

[0032] When the blank 100 moves to the chamfering station, the motor seats 421 on both sides move closer together. During the movement, the chamfering blade 432 pushes against the cleaning scraper 4354 through its gradually increasing outer diameter, causing the cleaning scraper 4354 to gradually change from an initial inclined position to a horizontal position. During this process, the hinge plate 437 becomes an auxiliary component and pulls the cleaning scraper 4354 simultaneously, thereby improving the smoothness of the chamfering blade 432's extension. (Specifically, the chamfering blade 432 and the connecting sleeve 433 are mounted on the output shaft of the motor 431 and move synchronously with the motor 431. The support frame 434 is fixedly mounted on the support base 41, and the base frame 4361 is fixedly mounted on the support frame 434. Therefore, the mounting ring 4362 fixedly connected to the base frame 4361 and the adjusting ring 4351 located inside the mounting ring 4362 do not move.) During its movement, the chamfering blade 432 gradually pushes the cleaning scraper 4354. A bearing ring is rotatably mounted on the connecting sleeve 433, and several circular rods are mounted on the bearing ring. The other ends of these circular rods slide through the mounting plate 4363 and connect to the telescopic plate 4368. It should be noted that the spring force on the telescopic plate 4368 is greater than the force of the top-pressure spring 4367. Therefore, during its movement, the connecting sleeve 433 pushes the telescopic plate 4368 through the circular rods. The telescopic plate 4368 then drives the adjusting seat 4366 to slide along the outer wall of the slide rod 4365, compressing the top-pressure spring 4367. Since the length of the hinge plate 437 remains constant, when the adjusting seat 4366 moves, it simultaneously pulls the cleaning scraper 4354 through the hinge plate 437, allowing the cleaning scraper 4354 to rotate more smoothly around the groove 4353.

[0033] After the chamfering of a single blank 100 is completed, the chamfering blades 432 on both sides are reset. During the reset process, the telescopic plate 4368 is reset first under force, while the cleaning scraper 4354 gradually rotates around the relief groove 4353 under the dual action of the torsion spring and the hinge plate 437, and finally comes into close contact with the working surface of the chamfering blade 432. As the chamfering blade 432 continues to rotate, the cleaning of metal chips from the cutting edge is completed.

[0034] It is worth emphasizing that this milling and chamfering machine has the following main advantages: Firstly, before the chamfering cutter 432 begins operation, it passes through the adjusting collar 4351. Several ball bearings 4352 are mounted on the material-bearing ring inside the adjusting collar 4351. The cutter shank of the chamfering cutter 432 is supported by these ball bearings 4352. When the chamfering cutter 432 is machining the blank 100, the cutting reaction force from the workpiece attempts to cause the cantilevered cutter to vibrate and deviate. However, at this time, the cutter shank is stably supported by the ball bearings 4352 inside the adjusting collar 4351, greatly enhancing the radial rigidity of the cutter. This rolling support design fundamentally solves the problem of minor vibrations and deviations caused by fatigue in cantilevered cutters. It is equivalent to adding a stable, low-friction auxiliary support point to the free end of the chamfering cutter 432, effectively suppressing chatter during long-term continuous operation, thereby ensuring that the machined chamfer dimensions always remain consistent with the design standards.

[0035] Secondly, when the chamfering cutter 432 is not in operation, the cleaning scraper 4354, under the combined action of the torsion spring and the hinge plate 437, remains in close contact with the cutting surface of the chamfering cutter 432. The motor 431 drives the chamfering cutter 432 to rotate continuously, allowing the cleaning scraper 4354 to remove metal chips adhering to it after the previous machining in real time. When the blank is 100mm from the workpiece and the chamfering cutter 432 feeds towards the workpiece, its increased outer diameter pushes the cleaning scraper 4354 to smoothly move aside without interfering with the machining. After machining is completed, the chamfering cutter 432 retracts, and the cleaning scraper 4354... The cleaning scraper 4354 immediately resets under the tension of the torsion spring and the hinge plate 437, and once again presses against the tool surface, preparing for the next cleaning. This dynamic and adaptive cleaning mechanism, through the cycle of "cleaning before processing, avoiding during processing, and resetting after processing", ensures that the chamfering tool 432 is in its optimal, chip-free original state before each processing. This fundamentally avoids batch dimensional anomalies caused by the built-up edge altering the tool geometry, and ensures that the chamfer width, depth, and angle of each workpiece meet the standards.

[0036] Thirdly, when the chamfering cutter 432 advances with the motor base 421, the cutter body pushes the cleaning scraper 4354. At the same time, the bearing ring connected to the connecting sleeve 433 pushes the telescopic plate 4368 through the circular rod. The telescopic plate 4368 then actively and synchronously pulls the cleaning scraper 4354 around the relief groove 4353 through the hinge plate 437, making the retraction action of the cleaning scraper 4354 very smooth and preventing it from jamming or popping off due to uneven force. This mechanical adaptive tool retraction design ensures a seamless connection between the cleaning and machining actions. It is not a passive process of being pushed away, but an active and coordinated retraction. This ensures that the cleaning scraper 4354 will not interfere with the tool or generate any additional resistance during the entire process of feeding and machining of the chamfering cutter 432, making the machining process smooth and stable.

[0037] Fourthly, during the reset process, the cleaning scraper 4354 receives a basic and continuous reset force from the torsion spring. The linkage mechanism, consisting of the telescopic plate 4368, the hinge plate 437, and the top pressure spring 4367, applies an additional upward pulling force to the cleaning scraper 4354 through the hinge plate 437, ensuring that it is tightly attached to the tool. Even if the torsion spring experiences slight force attenuation due to long-term operation, this linkage mechanism can still ensure that the cleaning scraper 4354 is reliably pressed against the surface of the chamfering tool 432. This redundant design of dual spring forces greatly improves the reliability of long-term operation of the equipment, fully considers the performance degradation problem that spring elements may experience under long-term, high-frequency operation, and avoids the loss of cleaning function due to the failure of a single spring, fundamentally ensuring the long-term stability of cleaning effect and processing quality.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
