Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a keyway machining table for a CNC lathe. Background Technology

[0002] Keyways are mainly located on drive shafts. A groove that matches the key is machined on the shaft or in the hole to fit and install the key in order to transmit torque.

[0003] Currently, keyway machining on CNC lathes mainly involves clamping the workpiece and then controlling the milling cutter to move relative to the workpiece to mill the groove. However, this method is mainly suitable for machining the outer keyway and is no longer applicable for machining the inner keyway. At the same time, the debris generated during the machining of the inner keyway will remain in the inner cavity of the workpiece and cause blockage, requiring multiple machine stops to clean the debris during the machining process. Therefore, this invention proposes a CNC lathe keyway machining table that can solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a keyway machining table for CNC lathes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a keyway machining table for a CNC lathe, comprising:

[0006] A seat beam on which a chuck for holding a workpiece is mounted, the chuck being fixedly abutted against the outer ring of the workpiece;

[0007] The supporting frame is movably connected to the seat beam;

[0008] A movable frame is located on a support frame. The movable frame is connected to a first moving rod and a second moving rod. A blade is installed at one end of the first moving rod. The second moving rod is connected to a liner rod through an adjustment component. A cleaning component is disposed on the liner rod. The cleaning component includes a ring body connected to the liner rod. A brush body is arranged around the outside of the ring body.

[0009] The power mechanism includes a motion component and a drive component. The motion component is used to adjust the coordinate position of the support frame on the seat beam. The drive component is used to drive the first moving rod and the bushing to reciprocate laterally in the inner cavity of the workpiece, so that the first moving rod processes the keyway in the inner cavity through the cutter head, and the bushing cleans the machining debris in the inner cavity of the workpiece through the cleaning component.

[0010] As a preferred embodiment of the present invention, the motion component includes a first screw, which extends longitudinally and is screwed with a longitudinal plate, the longitudinal plate being fixedly connected to the support frame.

[0011] As a preferred embodiment of the present invention, the motion component further includes a second screw, which is rotatably connected to the seat beam. The second screw extends laterally and is screwed to a horizontal plate. The first screw is rotatably connected to the horizontal plate, and the first screw and the second screw are respectively connected to a rotation source.

[0012] As a preferred technical solution of the present invention, the adjustment component includes a pad plate disposed on the second moving rod and a telescopic source mounted on the pad plate. The pad plate extends vertically upward, and the movable end of the telescopic source is connected to the bushing, so that the bushing forms a chip accumulation position below the side of the first moving rod away from the cutter head. When machining the keyway, the telescopic source drives the bushing away from the first moving rod, causing the center line of the ring body to overlap with the center line of the inner cavity of the workpiece, so that the brush body expands outward and makes uniform contact with the inner cavity wall of the workpiece.

[0013] As a preferred technical solution of the present invention, the driving component includes a guide rail and a power source disposed on the seat beam. The movable frame is slidably connected to the guide rail. The output shaft of the power source is connected to a swing arm. The swing arm is fitted with a sliding plate. The sliding plate is fixedly connected to the movable frame. The power source drives the swing arm to rotate around the output shaft, so that the swing arm moves along the fitting groove of the sliding plate.

[0014] As a preferred technical solution of the present invention, the cleaning component further includes an airbag disposed on the ring body. The airbag has an air inlet at the tail end and an air outlet at the head end. The air outlet is connected to a pipe passing through the ring body. The outer ring of the airbag is provided with a plurality of support straps. Each support strap has an insert section and an inlet section. The insert section can be inserted into the inlet section to make the support straps connect into a ring to support the airbag with toughness.

[0015] As a preferred technical solution of the present invention, the ring body is further provided with an elastic ring band, which can cover the airbag into a strip shape, so that the airbag can be inserted into the inner cavity from the front end of the workpiece and then removed from the rear end.

[0016] As a preferred technical solution of the present invention, a portion of the elastic ring can be turned outward and sleeved on the rear end of the workpiece, so that when the liner moves back and forth in the inner cavity of the workpiece, it pulls the airbag and another portion of the elastic ring to move back and forth into and out of the inner cavity of the workpiece. When the airbag enters the inner cavity, it contacts the other portion of the elastic ring and is squeezed by the inner cavity of the workpiece, which is used to reduce the volume of the airbag after being squeezed and discharge the air inside from the air outlet to blow the debris outward.

[0017] The present invention also provides a keyway processing method, specifically including the following steps:

[0018] S1. Clamp the outer ring of the workpiece with a chuck, and extend both ends of the workpiece out of the chuck;

[0019] S2. Adjust the coordinate position of the support frame on the seat beam through the motion component so that the cutter head and the ring body enter the inner cavity of the workpiece;

[0020] S3. Control the drive assembly to work, so that the first moving rod drives the cutter head to move laterally and reciprocally in the inner cavity of the workpiece to process the keyway, and the bushing drives the brush body to move laterally and reciprocally in the inner cavity of the workpiece to clean the processing debris.

[0021] Compared with the prior art, the beneficial effects of the present invention are: the present invention uses a drive assembly to make the first moving rod drive the cutting head to move laterally and reciprocally in the inner cavity of the workpiece to process the keyway;

[0022] With the combined action of brushing away debris and airflow blowing away debris, debris can be quickly discharged from the workpiece cavity during the machining of keyways, avoiding debris accumulation. This prevents a large number of debris from being dragged back and forth in the workpiece cavity during machining, thus avoiding numerous scratches in the workpiece cavity and keyway. This ensures the machining accuracy of the keyway in the workpiece cavity and improves the machining efficiency of the keyway in the workpiece cavity. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The present invention aims to automatically discharge machining debris while machining the keyway in the inner cavity of a workpiece, without having to stop the machine to clean the debris during the machining process. Please refer to the following embodiments for details.

[0034] Example 1

[0035] A keyway machining table for a CNC lathe is provided, comprising a seat beam 100, a support frame 300, a moving frame 400, and a power mechanism.

[0036] Please see Figure 1 A chuck 200 for clamping the workpiece is installed on the seat beam 100. The chuck 200 is fixed against the outer ring of the workpiece. The chuck 200 is open at both ends. A multi-jaw chuck 200 or other clamping disc that can be obtained from the existing market can be selected. The workpiece is kept stable by clamping the outer ring of the workpiece, so that the two ends of the workpiece can extend out when clamped, that is, it will not obstruct the inner cavity of the workpiece.

[0037] Please see Figure 1 , Figure 3 , Figure 5The support frame 300 is movably connected to the seat beam 100. The movable frame 400 is located on the support frame 300. The movable frame 400 is connected to a first moving rod 410 and a second moving rod 420. A cutter head 411 is installed at one end of the first moving rod 410. The second moving rod 420 is connected to a liner rod 430 through an adjusting component 600. A cleaning component 700 is arranged on the liner rod 430. The cleaning component 700 includes a ring body 710 connected to the liner rod 430. A brush body 711 is arranged around the outside of the ring body 710. The brush body 711 is preferably a soft brush that can move and contact the inner cavity wall of the workpiece to brush off the processing debris adhering to the inner cavity wall of the workpiece.

[0038] Please see Figure 1 The power mechanism includes a motion component 500 and a drive component 800. The motion component 500 is used to adjust the coordinate position of the support frame 300 on the seat beam 100. The drive component 800 is used to drive the first moving rod 410 and the bushing 430 to reciprocate laterally in the inner cavity of the workpiece, so that the first moving rod 410 processes the keyway in the inner cavity through the cutter head 411, and the bushing 430 cleans the machining debris in the inner cavity of the workpiece through the cleaning component 700.

[0039] Example 2

[0040] Based on Embodiment 1, a keyway machining table for CNC lathes is provided:

[0041] Please see Figure 5 , Figure 6 The cleaning component 700 also includes an airbag 720 disposed on the ring body 710. The airbag 720 has an air inlet 721 at its tail end and an air outlet 722 at its head end. The air outlet 722 is connected to a pipe 723 passing through the ring body 710. The outer ring of the airbag 720 is provided with several support straps 730. Each support strap 730 has a insertion section 731 and an inlet section 732. The insertion section 731 can be inserted into the inlet section 732 to connect the support straps 730 into a ring, which can resiliently support the airbag 720. Both the air inlet 721 and the air outlet 722 are unidirectional. The air inlet 721 can only allow air to enter. The air outlet 722 can only discharge air. The support band 730 is a metal band with toughness. The insertion segment 731 is located at one end of the support band 730, and the inlet segment 732 is located at the other end of the support band 730. The insertion segment 731 is inserted into the inlet segment 732, so that the support band 730 is connected into a ring and toughly supports the airbag 720. Thus, the airbag 720 is in an inflated state and can draw in air through the air inlet 721. When the support band 730 is subjected to circumferential force, the insertion segment 731 continues to be inserted into the inlet segment 732, so that the inner diameter of the connected ring support band 730 is reduced. Thus, the airbag 720 is in a compressed state and can discharge air through the air outlet 722.

[0042] Please see Figure 7Before machining the keyway, the airbag 720 naturally expands under the toughness of several support straps 730. It needs to be compressed before passing through the inner cavity of the workpiece. If it is compressed manually, it is inconvenient to operate. At the same time, if the airbag 720 passes directly through the inner cavity of the workpiece, it will rub against the inner cavity wall and cause it to break and leak air. Therefore, the ring body 710 is also provided with an elastic ring 740. The elastic ring 740 can cover the airbag 720 into a strip shape, so that the airbag 720 can enter the inner cavity from the front end of the workpiece and then move out from the rear end. The elastic ring 740 can be made of rubber material, so that the airbag 720 can pass through the inner cavity of the workpiece conveniently and without damage.

[0043] Please see Figure 8 A portion of the elastic band 740 can be folded outwards and fitted onto the rear end of the workpiece. This allows the liner 430 to pull the airbag 720 and the other portion of the elastic band 740 back and forth into and out of the workpiece cavity as the liner 430 reciprocates within the cavity. When the airbag 720 enters the cavity, it contacts the other portion of the elastic band 740 and is compressed by the workpiece cavity. This compression reduces the volume of the airbag 720, allowing the internal air to be expelled from the outlet 722, blowing debris outwards. By folding outwards and fitting the other portion of the elastic band 740 onto the rear end of the workpiece, it allows the other portion of the elastic band 740 to enter the workpiece cavity simultaneously with the airbag 720, acting as an intermediate separator. This prevents the airbag 720 from directly contacting the workpiece. The inner wall of the workpiece reduces wear on the airbag 720. When the airbag 720 moves out of the inner cavity, another part of the elastic ring 740 flips outward and detaches from the airbag 720. The airbag 720 expands and draws in air under the toughness of several support bands 730, preparing for the next entry into the inner cavity of the workpiece. Thus, with the combined action of the moving brush body 711 removing debris and the airflow blowing away debris, the debris can be quickly discharged from the inner cavity of the workpiece during the machining of the keyway, avoiding debris accumulation. That is, it avoids a large number of debris being dragged back and forth in the inner cavity of the workpiece during the machining process, causing a large number of scratches in the inner cavity and keyway of the workpiece, ensuring the machining accuracy of the keyway in the inner cavity of the workpiece, and improving the machining efficiency of the keyway in the inner cavity of the workpiece.

[0044] Example 3

[0045] Based on Embodiment 1 or Embodiment 2, a CNC lathe keyway machining table is provided:

[0046] Please see Figure 4 The adjustment assembly 600 includes a pad 610 disposed on the second moving rod 420 and a telescopic source 620 mounted on the pad 610. The pad 610 extends vertically upward, and the movable end of the telescopic source 620 is connected to the bushing 430, so that the bushing 430 forms a chip accumulation position below the side of the first moving rod 410 away from the cutter head 411. In other words, the chips generated from machining the keyway will not be blocked by the bushing 430. Thus, the chips generated from machining the keyway can be temporarily stored in the chip accumulation position area, which is convenient for subsequent discharge processing.

[0047] Please see Figure 4 As the machining of the keyway in the workpiece cavity needs to be gradually deepened, the brush body 711 will also gradually move closer to the machining keyway side, causing a gap between the brush body 711 and the inner wall of the workpiece cavity. Therefore, when machining the keyway, the telescopic source 620 drives the bushing 430 away from the first moving rod 410, causing the center line of the ring body 710 to overlap with the center line of the inner cavity of the workpiece, so that the brush body 711 expands outward and evenly contacts the inner wall of the workpiece cavity. The telescopic source 620 is preferably a miniature electric cylinder. The power supply wire of the telescopic source 620 can be passed through the pad 610 and the first moving rod 410 to avoid being scratched. In order to ensure the stability of the lateral displacement of the bushing 430 under the drive of the telescopic source 620, the pad 610 is provided with a telescopic rod 630 connected to the bushing 430.

[0048] Example 4

[0049] Based on any of the above embodiments, a CNC lathe keyway machining table is provided:

[0050] Please see Figure 3 The drive assembly 800 includes a guide rail 810 and a power source 820 mounted on the seat beam 100. The movable frame 400 is slidably connected to the guide rail 810. The output shaft of the power source 820 is connected to a swing arm 830. The swing arm 830 is fitted with a sliding plate 840. The sliding plate 840 is fixedly connected to the movable frame 400. The power source 820 drives the swing arm 830 to rotate around the output shaft, causing the swing arm 830 to move along the fitting groove of the sliding plate 840. The power source 820 is preferably a servo motor. By driving the swing arm 830 to rotate and move along the fitting groove of the sliding plate 840, the reciprocating motion of the sliding plate 840 drives the movable frame 400 to reciprocate on the guide rail 810, thereby driving the first moving rod 410 and the bushing 430 to reciprocate laterally in the inner cavity of the workpiece to realize the keyway machining and debris removal of the workpiece.

[0051] Please see Figure 2 The motion component 500 includes a first screw 510, which extends longitudinally and is screwed to a longitudinal plate 520. The longitudinal plate 520 is fixedly connected to the support frame 300. The motion component 500 also includes a second screw 530, which is rotatably connected to the seat beam 100. The second screw 530 extends laterally and is screwed to a horizontal plate 540. The first screw 510 is rotatably connected to the horizontal plate 540. The first screw 510 and the second screw 530 are respectively connected to a rotation source 550, preferably a motor. When machining the keyway, by driving the first screw 510 and the second screw 530 to rotate, the position of the support frame 300 on the seat beam 100 is adjusted, that is, the cutter head 411 can enter the inner cavity of the workpiece. During the machining of the keyway, the longitudinal position is gradually adjusted, and a keyway of the required depth can be machined.

[0052] Example 5

[0053] A keyway machining method specifically includes the following steps:

[0054] S1. Clamp the outer ring of the workpiece with chuck 200, and make both ends of the workpiece extend out of chuck 200;

[0055] S2. Adjust the coordinate position of the support frame 300 on the seat beam 100 by the motion component 500, so that the cutter head 411 and the ring body 710 enter the inner cavity of the workpiece.

[0056] S3. The control drive assembly 800 is activated, causing the first moving rod 410 to drive the cutter head 411 to reciprocate laterally in the inner cavity of the workpiece to process the keyway, and causing the bushing rod 430 to drive the brush body 711 to reciprocate laterally in the inner cavity of the workpiece through the ring body 710 to clean the processing debris.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
