Description

Technical Field

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

[0002] A collet is a locking device for clamping cutting tools or workpieces, commonly used on milling machines and machining centers. It clamps the tool through elastic deformation, making it suitable for high-speed cutting and high-efficiency machining. A collet generally consists of an outer sleeve, a clamping nut, and a spring collet. In use, the spring collet is placed inside the outer sleeve, the tool shaft is then inserted into the spring collet, and finally, the clamping nut on the outer sleeve is tightened, causing radial compression of the spring collet and thus clamping the tool or workpiece.

[0003] Currently, when processing the elastic chuck of the collet, the bar stock is first clamped on the three-jaw chuck of the machine tool. Then, the outer shape and inner hole of the elastic chuck are machined by turning. After that, two sets of gaps are cut at equal intervals along the circumference of the bar stock by cutting. The two sets of gaps are arranged alternately, so that one set of gaps penetrates the top of the elastic chuck and the other set of gaps penetrates the bottom of the elastic chuck.

[0004] In existing technologies, when cutting bar stock, the cutting can only be done by rotating the bar stock and cutting it point by point. This results in low processing efficiency. Furthermore, during the cutting process, metal chips on the bar stock are easily splashed into the inner hole of the bar stock. This causes the hot chips to adhere to the inner wall of the inner hole of the bar stock, resulting in unevenness on the inner surface of the elastic collet and thus reducing the stability of the collet in holding the workpiece. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a machine tool workpiece processing technology, including the following steps: S1, the worker centers and clamps the bar stock on the three-jaw chuck of the machine tool, then rotates the bar stock through the three-jaw chuck, and at the same time performs turning processing on the outer and inner sides of the bar stock through a cutting tool.

[0006] S2. Move the cutting device to the outside of the bar stock, start the cutting device to cut all the cutting positions on the bar stock simultaneously, and at the same time protect the inside of the bar stock through the cutting device.

[0007] S3. After cutting, the bar stock is rotated by a three-jaw chuck so that the cutting device cleans the debris inside the bar stock.

[0008] S4. Move the cutting device to the initial position and use the cutting tool to cut the processed collet off the bar stock.

[0010] The cutting mechanism includes an outer moving frame that slides left and right on the outside of the mounting bracket, and an inner moving frame that slides left and right on the inside of the mounting bracket. Extension plates are fixedly installed at equal intervals along the circumference on the left side of both the outer and inner moving frames.

[0013] In one possible implementation, the protective assembly includes a protective shell that is radially slidably disposed on the outside of the cleaning brush plate along the fixed sleeve. A return spring is disposed between the protective shell and the cleaning brush plate. The left side of the fixed sleeve has straight grooves evenly spaced along its circumference. The protective shell slides inside the straight grooves via a protruding post on its right side. A rotating post is rotatably disposed inside the fixed sleeve. Right-angled trapezoidal grooves are evenly spaced along its circumference on the left side of the rotating post. The protruding post is inserted into the right-angled trapezoidal grooves. A driving part for driving the rotation of the rotating post is disposed on the right side.

[0014] In one possible implementation, the drive unit includes an active turntable rotatably disposed on the right side of the rotating column. The left side of the active turntable has hemispherical grooves evenly spaced along its circumference. The right side of the rotating column has limiting steel balls that slide left and right inside it at equal intervals along its circumference. An active spring is disposed between the limiting steel balls and the rotating column. The active turntable is connected to the output shaft of the actuator motor via a belt. An arc-shaped friction plate that abuts against the outer surface of the rotating column is slidably disposed on the right side of the mounting bracket. A push spring is disposed between the arc-shaped friction plate and the mounting bracket.

[0015] In one possible implementation, the moving assembly includes a position plate that is slidably disposed between the upper parts of the outer moving frame and the inner moving frame. A synchronous gear is rotatably disposed in the middle of the right side of the position plate. Moving racks that mesh with the synchronous gear are slidably disposed in the upper and lower parts of the right side of the position plate. The upper moving rack is fixedly connected to the outer moving frame, and the lower moving rack is fixedly connected to the inner moving frame. A first electric push rod is fixedly installed on the right side of the position plate. The telescopic section of the first electric push rod is fixedly connected to the inner moving frame. A second electric push rod is fixedly installed on the upper right side of the mounting bracket. The telescopic section of the second electric push rod is fixedly connected to the position plate.

[0016] In one possible implementation, the fixing component includes a rotating disk rotatably disposed on the left side of the mounting bracket, with abutment members equidistantly disposed on the left side of the rotating disk along its circumference and sliding radially thereon, an active disk plate rotatably disposed on the left side of the rotating disk, and an end face thread disposed on the right side of the active disk plate, the active disk plate being threadedly engaged with the abutment members.

[0017] In one possible implementation, the lifting assembly includes a movable ear seat that is slidably disposed on the insertion tube. A first connecting rod is hinged at equal intervals along the circumference of the movable ear seat. The right end of the first connecting rod is hinged to a cleaning brush plate at a corresponding position.

[0018] In one possible implementation, the limiting component includes a support plate fixedly installed on the outer right side of the cleaning brush plate, a limiting plate fixedly installed on the side of the support plate away from the cleaning brush plate, the left side of the limiting plate being in the same plane as the left side of the insertion tube, and abutment blocks fixedly installed on both sides of the movable frame.

[0019] The beneficial effects of this invention are as follows:

[0020] I. The present invention employs a moving component that can simultaneously move the cutting saw blades on the outer moving frame and the inner moving frame, so that the cutting saw blades on the outer moving frame and the inner moving frame can simultaneously cut the two sets of gaps on the elastic chuck, thereby greatly reducing the processing time and improving the processing efficiency.

[0021] Second, this invention uses a lifting component to drive a cleaning brush plate against the inner wall of the elastic chuck. The cleaning brush plate and the protective component can guide the debris generated during cutting, causing the high-temperature metal debris to splash onto the sponge. The sponge then buffers and absorbs the metal debris, preventing it from bouncing again and collecting it. After cutting, by moving the protective component and rotating the elastic chuck, the cleaning brush plate can sweep and clean the inner wall of the elastic chuck, further ensuring the flatness of the inner wall of the elastic chuck and increasing the stability of the subsequent workpiece clamping by the collet.

[0022] Third, the protective component of this invention can guide metal debris during cutting and protect the cleaning brush plate at the same time, preventing high-temperature debris from adhering to the bristles of the cleaning brush plate, which would cause the metal debris to scratch the inner wall of the elastic chuck when the cleaning brush plate brushes against it.

[0023] Fourth, the present invention can automatically determine the feed depth of the cutting saw blade according to the inner diameter of the elastic chuck by using the limiting component, so that the cutting saw blade can automatically cut through elastic chucks of various inner diameters, which increases the adaptability of the present invention, and saves the adjustment steps of the cutting saw blade feed depth by means of adaptive method, thereby further increasing the processing efficiency.

[0024] Fifth, the fixing component of this invention can fix the mounting bracket at the coaxial position of the bar, which increases the stability of the mounting bracket, prevents the cutting saw blade from shaking during cutting, and ensures the cutting effect. In addition, the fixing component can increase the coaxiality of the outer moving frame, the inner moving frame and the bar, thereby further ensuring the cutting effect of the cutting saw blade.

[0043] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] See Figure 1 A machine tool workpiece machining process includes the following steps:

[0045] S1. The worker centers and clamps the bar stock onto the three-jaw chuck of the machine tool, then rotates the bar stock through the three-jaw chuck while simultaneously machining the outer and inner sides of the bar stock with a cutting tool.

[0046] S2. Move the cutting device to the outside of the bar stock, start the cutting device to cut all the cutting positions on the bar stock simultaneously, and at the same time protect the inside of the bar stock through the cutting device.

[0047] S3. After cutting, the bar stock is rotated by a three-jaw chuck so that the cutting device cleans the debris inside the bar stock.

[0048] S4. Move the cutting device to the initial position and use the cutting tool to cut the processed collet off the bar stock.

[0049] Steps S2 and S3 are completed using a machine tool workpiece processing device, see reference. Figure 2 , Figure 5 and Figure 10 The machine tool workpiece processing device includes an electric slide block 1, an installation bracket 2 fixedly mounted on the upper part of the electric slide block 1, a slitting mechanism 3 for simultaneously cutting all cutting points of the bar stock on the installation bracket 2, and a chip removal mechanism 4 for protecting and cleaning the inside of the bar stock inside the installation bracket 2.

[0050] When it is necessary to cut the bar stock, the electric slider 1 is moved to the left, so that the electric slider 1 drives the mounting bracket 2 to move and cover the outside of the three-jaw chuck. Then, the mounting bracket 2 is fixed on the coaxial position of the three-jaw chuck by the cutting mechanism 3. Then, the bar stock is cut again by the cutting mechanism 3, and then the debris inside the bar stock is cleaned by the chip removal mechanism 4.

[0051] See Figure 2 , Figure 11 and Figure 15 The chip removal mechanism 4 includes a fixed sleeve 41 fixedly installed at the axial position of the mounting bracket 2, and an insertion tube 42 fixedly installed on the left side.

[0052] When the mounting bracket 2 moves to the left, the mounting bracket 2 drives the insertion tube 42 to be inserted into the inner hole of the bar through the fixing sleeve 41. When the left side of the insertion tube 42 abuts against the left side of the inside of the bar, the mounting bracket 2 stops moving.

[0053] See Figure 2 , Figure 3 and Figure 4 The slitting mechanism 3 includes a fixing component 38 disposed on the left side of the mounting bracket 2 for fixing its position. The fixing component 38 includes a rotating disk 381 rotatably disposed on the left side of the mounting bracket 2. Abutment members 382 that slide radially are disposed at equal intervals along the circumference of the rotating disk 381. An active disk plate 383 is rotatably disposed on the left side of the rotating disk 381. An end face thread is disposed on the right side of the active disk plate 383. The active disk plate 383 and the abutment members 382 are threadedly engaged.

[0054] When the left side of the insertion tube 42 abuts against the left side of the inside of the bar stock, the mounting bracket 2 drives the rotating disk 381 to move to the outside of the three-jaw chuck. Then, the operator holds the rotating disk 381 still and manually rotates the active disk plate 383, causing the active disk plate 383 to drive the abutment 382 to move radially inward, so that the abutment 382 abuts against the outside of the three-jaw chuck, thereby fixing the rotating disk 381 in the coaxial position of the bar stock. At the same time, the rotating disk 381 drives the mounting bracket 2 to be fixed in the coaxial position of the bar stock.

[0055] See Figure 2 , Figure 5 , Figure 6 and Figure 8 The cutting mechanism 3 also includes an outer movable frame 31 that is slidably disposed on the outside of the mounting bracket 2, and an inner movable frame 32 that is slidably disposed on the inside of the mounting bracket 2. An extension plate 33 is fixedly installed on the left side of both the outer movable frame 31 and the inner movable frame 32 at equal intervals along their circumference. A movable frame 34 is slidably disposed on the side of the extension plate 33 away from the outer movable frame 31 and the inner movable frame 32 along the radial direction of the mounting bracket 2. A cutting saw blade 35 is rotatably disposed at one end of the movable frame 34 near the axis of the mounting bracket 2.

[0056] When the mounting bracket 2 is fixed at the coaxial position of the bar stock, the mounting bracket 2 drives the outer moving frame 31 and the inner moving frame 32 to be synchronously located at the coaxial position of the bar stock, so that the outer moving frame 31 and the inner moving frame 32 drive the cutting saw blade 35 to surround the outside of the bar stock through the extension plate 33 and the moving frame 34.

[0057] See Figure 2 , Figure 10 , Figure 13 , Figure 14 and Figure 16 The cleaning mechanism 4 also includes cleaning brushes 43 that are equally spaced along the circumference of the insertion tube 42 on its outer side. The cleaning brushes 43 are slidably connected to the insertion tube 42 along the radial direction via a lifting assembly 44.

[0058] See Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15The lifting assembly 44 includes a movable ear 441 that is slidably mounted on the insertion tube 42. A first connecting rod 442 is hinged at equal intervals along the circumference of the movable ear 441. The right end of the first connecting rod 442 is hinged to a cleaning brush plate 43 at a corresponding position. A movable block 443 is slidably mounted on the side of the cleaning brush plate 43 near the insertion tube 42. A second connecting rod 444 is hinged to the movable block 443. The right end of the second connecting rod 444 is hinged to the insertion tube 42. The middle parts of the first connecting rod 442 and the second connecting rod 444 at corresponding positions are rotatably connected to each other. An adjusting threaded rod 445 is rotatably mounted inside the insertion tube 42. The adjusting threaded rod 445 is threadedly connected to the movable ear 441.

[0059] After the mounting bracket 2 is fixed in position, the operator manually rotates the adjusting threaded rod 445, causing the adjusting threaded rod 445 to move the movable ear 441 to the right. The movable ear 441 pushes the first connecting rod 442. Since the first connecting rod 442 and the second connecting rod 444 form a scissor-type lifting structure, the first connecting rod 442 and the second connecting rod 444 together drive the cleaning brush plate 43 to move away from the insertion tube 42, so that the side of the cleaning brush plate 43 away from the insertion tube 42 abuts against the inner wall of the bar stock.

[0060] See Figure 13 , Figure 16 and Figure 17 The cleaning mechanism 4 also includes a sponge 45 fixedly installed on the outside of the insertion tube 42 and located between two adjacent cleaning brush plates 43. A protective component 46 is provided on the fixed sleeve 41 to protect the cleaning brush plates 43. The protective component 46 includes a protective shell 461 that is slidably disposed on the outside of the cleaning brush plates 43 along the radial direction of the fixed sleeve 41. A return spring is provided between the protective shell 461 and the cleaning brush plates 43.

[0061] When the cleaning brush plate 43 abuts against the inner wall of the bar stock, the cleaning brush plate 43, through the return spring, drives the protective shell 461 to abut against the inner wall of the bar stock, so that the protective shell 461 covers the outside of the cleaning brush plate 43, preventing metal debris from splashing onto the cleaning brush plate 43 during cutting. The two adjacent protective shells 461 and the cleaning brush plate 43 are located on both sides of the bar stock to be cut. At this time, the sponge 45 corresponds to the bar stock to be cut, so that the protective shell 461 and the cleaning brush plate 43 can guide the metal debris during cutting onto the sponge 45, thereby allowing the sponge 45 to receive the metal debris.

[0062] See Figure 6 , Figure 8 , Figure 10 and Figure 13The cleaning mechanism 4 also includes a limiting component 47 disposed on the cleaning brush plate 43 for limiting the movement frame 34. The limiting component 47 includes a support plate 471 fixedly installed on the outer right side of the cleaning brush plate 43. A limiting plate 472 is fixedly installed on the side of the support plate 471 away from the cleaning brush plate 43. The left side of the limiting plate 472 is in the same plane as the left side of the insertion tube 42. Abutment blocks 473 are fixedly installed on both sides of the movement frame 34.

[0063] When the cleaning brush plate 43 abuts against the inner wall of the bar stock, the cleaning brush plate 43 drives the limiting plate 472 to move outward to the corresponding position through the support plate 471.

[0064] See Figure 5 , Figure 6 and Figure 7 The cutting mechanism 3 also includes a moving component 36 mounted on the mounting bracket 2 for driving the outer moving frame 31 and the inner moving frame 32 to move synchronously. The moving component 36 includes a position plate 361 that is slidably mounted on the upper part of the outer moving frame 31 and the inner moving frame 32. A synchronous gear 362 is rotatably mounted on the middle right side of the position plate 361. Moving racks 363 that mesh with the synchronous gear 362 are slidably mounted on the upper and lower right sides of the position plate 361. The upper moving rack 363 is fixedly connected to the outer moving frame 31, and the lower moving rack 363 is fixedly connected to the inner moving frame 32. A first electric push rod 364 is fixedly mounted on the right side of the position plate 361. The telescopic section of the first electric push rod 364 is fixedly connected to the inner moving frame 32. A second electric push rod 365 is fixedly mounted on the upper right side of the mounting bracket 2. The telescopic section of the second electric push rod 365 is fixedly connected to the position plate 361.

[0065] In the initial state, the telescopic section of the first electric push rod 364 is extended, causing the first electric push rod 364 to push the inner moving frame 32 to the left. The inner moving frame 32 drives the lower moving rack 363 to move to the left in sync. The lower moving rack 363 drives the synchronous gear 362 to rotate. The synchronous gear 362 drives the outer moving frame 31 to move to the right through the upper moving rack 363. Thus, the inner moving frame 32 and the outer moving frame 31 are initially in a position away from each other. The inner moving frame 32 and the outer moving frame 31 also drive the cutting saw blade 35 connected to them to be in a position away from each other.

[0066] When the cleaning brush plate 43 abuts against the inner wall of the bar stock, the telescopic section of the second electric push rod 365 extends, causing the second electric push rod 365 to move the position plate 361 to the left. The position plate 361 drives the inner moving frame 32 and the outer moving frame 31 to move to the left synchronously through the synchronous gear 362 and the moving rack 363. When the synchronous gear 362 moves to the middle of the bar stock to be cut, the extension of the telescopic section of the second electric push rod 365 stops, so that the inner moving frame 32 drives the cutting saw blade 35 connected to it to be located on the left side of the bar stock, while the outer moving frame 31 drives the cutting saw blade 35 connected to it to be located on the right side of the bar stock.

[0067] See Figure 5 , Figure 6 , Figure 8 and Figure 9 The cutting mechanism 3 also includes a feed assembly 37 mounted on the mounting bracket 2 for synchronously feeding all the moving frames 34. A power motor 39 is fixedly mounted on the moving frame 34, and the power motor 39 is connected to the cutting saw blade 35 at the corresponding position via a timing belt.

[0068] When the cutting saw blade 35 is positioned on both sides of the bar stock, the power motor 39 is started to drive the cutting saw blade 35 to begin rotating.

[0069] See Figure 2 , Figure 5 , Figure 6 , Figure 8 and Figure 9 The feed assembly 37 includes rotating rods 371 that are rotatably mounted on the mounting bracket 2 at equal intervals along its circumference. An active gear 372 is rotatably mounted on the left side of the extension plate 33. The active gear 372 is slidably sleeved on the outside of the rotating rods 371 at the corresponding position. A driven rack 373 is fixedly mounted on the moving frame 34. The active gear 372 meshes with the driven rack 373. The right ends of the rotating rods 371 are connected to each other by a belt. An actuator motor 374 is fixedly mounted on the right side of the mounting bracket 2. The output shaft of the actuator motor 374 is connected to one of the rotating rods 371 by a belt.

[0070] When the cutting saw blade 35 starts to rotate, the start-up motor 374 drives the rotating rod 371 connected to it to rotate, so that all the rotating rods 371 start to rotate synchronously through the belt. The rotating rods 371 drive the drive gear 372 on them to rotate. The drive gear 372 drives the moving frame 34 to move closer to the bar material radially through the driven rack 373, so that the moving frame 34 drives the rotating cutting saw blade 35 to cut the bar material.

[0071] When the moving frame 34 moves, the moving frame 34 drives the abutment block 473 on it to move synchronously. When the abutment block 473 moves to abut against the limit plate 472, the rotating actuator 374 stops. At this time, the cutting saw blade 35 is fed to cut through the bar. Then, the extension section of the first electric push rod 364 is retracted, which drives the inner moving frame 32 and the outer moving frame 31 to move closer to each other. This causes the inner moving frame 32 and the outer moving frame 31 to drive the cutting saw blade 35 connected to them to move to the left and right exchange positions, thereby completing the cutting of the bar and processing the right side of the bar into an elastic chuck.

[0072] After the cutting is completed, the reverse motor 374 is reversed, causing the motor 374 to drive the cutting saw blade 35 away from the elastic chuck. Then the power motor 39 is stopped, causing the cutting saw blade 35 to stop rotating. At the same time, the extension section of the first electric push rod 364 is extended to the initial position, causing the inner moving frame 32 and the outer moving frame 31 to drive the cutting saw blade 35 connected to them to reset.

[0073] See Figure 10 , Figure 11 , Figure 13 , Figure 15 and Figure 17 The protective assembly 46 includes a protective shell 461 that is slidably disposed radially on the outside of the cleaning brush plate 43 along the fixed sleeve 41. A return spring is provided between the protective shell 461 and the cleaning brush plate 43. The left side of the fixed sleeve 41 has straight grooves at equal intervals along its circumference. The protective shell 461 slides inside the straight grooves through the protruding post on its right side. A rotating post 462 is rotatably disposed inside the fixed sleeve 41. Right-angled trapezoidal grooves 463 are provided at equal intervals along its circumference on the left side of the rotating post 462. The protruding post is inserted into the right-angled trapezoidal groove 463. A driving part 464 for driving the rotation of the rotating post 462 is provided on the right side of the rotating post 462.

[0074] See Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 15 and Figure 17 The drive unit 464 includes an active turntable 4641 rotatably disposed on the right side of the rotating column 462. The active turntable 4641 has hemispherical grooves evenly spaced along its circumference on its left side. The rotating column 462 has limiting steel balls 4642 slidably disposed inside it along its circumference on its right side. An active spring is disposed between the limiting steel balls 4642 and the rotating column 462. The active turntable 4641 is connected to the output shaft of the actuator motor 374 via a belt. An arc-shaped friction plate 4643 is slidably disposed on the right side of the mounting bracket 2, abutting against the outer surface of the rotating column 462. A push spring is disposed between the arc-shaped friction plate 4643 and the mounting bracket 2.

[0075] When the actuator motor 374 drives the cutting saw blade 35 to move inward, the actuator motor 374 synchronously drives the drive turntable 4641 to rotate, so that the drive turntable 4641 drives the rotating column 462 to rotate through the limiting steel ball 4642. The right-angled side of the right-angled trapezoidal groove 463 on the rotating column 462 abuts against the protruding column of the protective shell 461, so that the rotating column 462 cannot rotate. This causes the drive turntable 4641 to push the limiting steel ball 4642 to the left, so that the drive turntable 4641 cannot drive the rotating column 462 to rotate.

[0076] When the actuator motor 374 drives the cutting saw blade 35 to move outward, the drive turntable 4641 reverses, causing the inclined side of the right-angled trapezoidal groove 463 on the drive turntable 4641 to abut against the protruding post of the protective shell 461. This causes the inclined side of the right-angled trapezoidal groove 463 to push the protruding post of the protective shell 461 towards the insertion tube 42, thereby moving the protective shell 461 to a position where it no longer protects the cleaning brush plate 43. When the protective shell 461 moves to its maximum position towards the insertion tube 42, the drive turntable 4641 pushes the limiting steel ball 4642 to the left, preventing the drive turntable 4641 from driving the rotating column 462 to rotate. The push spring pushes the arc-shaped friction plate 4643 to always abut against the rotating column 462, thereby preventing the rotating column 462 from rotating without external force, and ensuring that the protective shell 461 does not contact the inner wall of the elastic chuck.

[0077] Once the protective shell 461 is no longer in contact with the inner wall of the elastic chuck, the three-jaw chuck is rotated, causing the elastic chuck to rotate, thereby allowing the cleaning brush plate 43 to brush and clean the inner wall of the elastic chuck.

[0078] In embodiments of the present invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0079] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," "installed," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, or a sliding connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
