Description

Technical Field

[0001] This application relates to the field of acupuncture needle processing, and more specifically, to a precision processing device for acupuncture needles that can collect waste materials. Background Technology

[0002] Acupuncture needles typically consist of a needle body, a needle tip, a needle handle, and / or a cannula. The needle tip is located at the front end of the needle body, and the needle handle is located at the rear end. Both the needle body and the needle tip are smooth, while the needle handle is often threaded. Used in traditional Chinese medicine acupuncture treatment, the needle tip is cut using laser cutting equipment during the manufacturing process.

[0003] Patent document CN110842356A discloses a laser machine tool for automatic waste cleaning. This invention relates to the field of laser machine tool technology and discloses a laser machine tool for automatic waste cleaning, including a machine body. An inverted "U"-shaped support frame is fixedly connected to the center of the upper part of the machine body. A cylinder is fixedly connected to the bottom of the inner frame of the support frame, and a laser head is fixedly connected to the piston end of the cylinder. A dual-axis motor and a collection box are fixedly connected to the top of the outer frame of the support frame. Both ends of the dual-axis motor are connected to a waste suction mechanism via couplings. The mechanism is connected to the collection box; the chip suction mechanism includes a support plate, a reciprocating lead screw, a lead screw slider, a chip suction pipe with an opening at the lower end, a fan, a battery, and a bellows. The support plate is fixedly connected to the upper end of the machine body. One end of the reciprocating lead screw is connected to one output end of a dual-axis motor through a coupling. The above-mentioned application uses a laser head to cut materials. However, the angle of the laser head is not easy to adjust. When it is necessary to cut a conical structure at the needle tip position, it is not convenient to cut by adjusting the angle of the laser head, which is not convenient for precision machining.

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0019] See Figures 1-8This embodiment provides a precision machining device for acupuncture needles that can collect waste materials. It includes a base plate 1, a laser beam generator 2 fixedly connected to the top of the base plate 1, a cutting head 3 located on the left side of the laser beam generator 2, and an optical cable (not shown) connecting the laser beam generator 2 and the cutting head 3. A material carrier 6 is fixedly connected to the top of the base plate 1, and an adjustment assembly 4 is located on the top of the base plate 1. The adjustment assembly 4 includes a support base 401 with an annular support. The support base 401 is fixedly connected to the left side of the laser beam generator 2. A rotating seat 402 is rotatably connected to the inner surface of the support base 401. The rotating seat 402 is connected to the inner surface of the annular support on the support base 401 via a bearing, allowing the rotating seat 402 to rotate on the inner surface of the annular support on the support base 401. A first support plate 403 is fixedly connected below the rotating seat 402. A first gear 404 is rotatably connected to the front of the first support plate 403. A connecting column 405 is fixedly connected to the front of the first gear 404. The connecting column 405 is fixedly connected to the top of the cutting head 3. The cutting head 3 is eccentrically positioned between itself and the rotation axis of the rotating seat 402 in a vertical state. A cover assembly 7 is provided on the front of the first gear 404. A drive assembly 5 is provided above the laser beam generator 2. The drive assembly 5 includes a hydraulic push rod 501, which is fixedly connected to the top of the laser beam generator 2. The hydraulic push rod 501 is used to drive the lifting seat 502 to rise and fall. The upper end of the hydraulic push rod 501 is fixedly connected to the lifting seat 502, which is L-shaped. 02 Two connecting rods 503 are fixedly connected to both sides of the laser beam generator 2. A lifting frame 504, H-shaped, is fixedly connected to the lower end of each connecting rod 503. The lifting frame 504 is slidably connected to the left side of the laser beam generator 2. A slide rail is provided on the left side of the laser beam generator 2 for the vertical sliding of the lifting frame 504. A limit block is provided at the lower end of the slide rail. Two connecting arms 505 are fixedly connected to the left side of the lifting frame 504. A rotating shaft 514 is positioned between the two connecting arms 505. An adjusting ring 506 is fixedly connected to the left end of each connecting arm 505. The inner surface of the adjusting ring 506 is inclined. A second support plate 507 is fixedly connected below the rotating seat 402. The second support plate 507 has a tooth for passing through. The opening of bar 511 allows the right side of the second support plate 507 to pass through a limiting rod 508. A limiting block is provided at the left end of the limiting rod 508 to prevent it from coming off the second support plate 507. A ball bearing seat 509 is fixedly connected to the right end of the limiting rod 508. A spring 510 is elastically connected between the ball bearing seat 509 and the second support plate 507. Under normal conditions, the spring 510 will apply elastic force to push the ball bearing seat 509 toward the inner surface of the adjusting ring 506. A rack 511 is fixedly connected to the left side of the ball bearing seat 509. The rack 511 meshes with the lower part of the first gear 404. A ball bearing 512 is slidably connected to the inner surface of the ball bearing seat 509. The ball bearing 512 can rotate arbitrarily 360 degrees on the inner surface of the ball bearing seat 509. The ball bearing 512 is slidably connected to the inner surface of the adjusting ring 506.

[0020] In practical use, the metal rod-shaped raw material is first fixed on the clamp 8 on the loading platform 6. Then, the hydraulic push rod 501 is activated to drive the lifting seat 502 to descend. The descent of the lifting seat 502 will drive the connecting rod 503 to lower the lifting frame 504 on the slide rail to the left of the laser beam generator 2. The descent of the lifting frame 504 will drive the connecting arm 505 to lower the adjusting ring 506. At this time, the inner diameter of the adjusting ring 506 at the horizontal plane of the ball 512 will decrease. The adjusting ring 506 will push against the ball 512, thereby driving the ball seat 509 to move to the left. This will cause the limiting rod 508 to slide to the right within the second support plate 507, thereby compressing the spring 510. The leftward movement of the ball seat 509 will also drive the rack 511 to move to the left. The rack 511 will then... The first gear 404 is rotated clockwise. The clockwise rotation of the first gear 404 will drive the connecting column 405 to shift the cutting head 3 to the left by a certain angle, so as to facilitate the cutting of a conical needle tip. When new material needs to be placed, the hydraulic push rod 501 is activated to drive the lifting seat 502 to rise. At this time, the lifting frame 504 will drive the connecting arm 505 to raise the adjusting ring 506. The inner diameter of the adjusting ring 506 at the horizontal plane of the ball 512 will expand. The compressed spring 510 will release its elastic force and push against the ball seat 509 to make the ball 512 fit against the inner surface of the adjusting ring 506. At this time, the rack 511 will move to the right. The rack 511 will drive the first gear 404 to rotate counterclockwise, which will drive the connecting column 405 to make the cutting head 3 vertical again. Example 2

[0021] See Figures 4-8Based on Embodiment 1, the drive assembly 5 further includes a motor 513, with its output end facing downwards. The motor 513 is fixedly connected to the left side of the lifting seat 502. A limiting plate 516 movably passes through the top of the lifting seat 502, limiting the lifting seat 502 during lifting. The limiting plate 516 is fixedly connected to the top of the laser beam generator 2. A rotating shaft 514 is fixedly connected to the output end of the motor 513 via a coupling, enabling the motor 513 to drive the rotating shaft 514 to rotate. The rotating shaft 514 movably passes through the top of the support base 401, which has a through hole for the rotating shaft 514. A first inclined plate is fixedly connected to the outer surface of the rotating shaft 514. The gear 515 and the adjusting assembly 4 also include a third helical gear 406, which is fixedly connected to the outer surface of the rotating seat 402. A second helical gear 407 is meshed on the left side of the third helical gear 406. The second helical gear 407 is rotatably connected to the upper part of the support seat 401. The second helical gear 407 is adapted to the first helical gear 515. After the first helical gear 515 is lowered, it can mesh with the second helical gear 407. The covering assembly 7 includes a second gear 701, which is rotatably connected to the front of the first support plate 403. The second gear 701 meshes with the upper part of the first gear 404. A blocking seat 702 is fixedly connected to the front of the second gear 701. The blocking seat 702 is L-shaped.

[0022] In practical use, when the first gear 404 rotates clockwise, it also drives the second gear 701 to rotate counterclockwise. The counterclockwise rotation of the second gear 701 causes the blocking seat 702 to shift to the right, moving it away from under the cutting head 3 to allow the cutting head 3 to operate. Simultaneously, as the hydraulic push rod 501 lowers the lifting seat 502, it also lowers the motor 513. The lowering of the motor 513 causes the rotating shaft 514 to lower, which in turn causes the first helical gear 515 to lower. After lowering, the first helical gear 515 meshes with the second helical gear 407. At this point, the motor 513 is activated, causing the rotating shaft 514 to rotate. The rotation of the rotating shaft 514 then drives the first helical gear 515 to rotate, which in turn drives the second helical gear 407 to rotate. The rotation of the second helical gear 407 drives the third helical gear 406 to rotate, which in turn drives the rotating seat 402 to rotate within the support seat 401. The rotation of the rotating seat 402 drives the first support plate 403, the first gear 404, the connecting column 405, and the cutting head 3 to rotate. The rotation of the rotating seat 402 also drives the second support plate 507 and the limiting rod 508 to make the balls 512 on the ball bearing seat 509 roll on the inner surface of the adjusting ring 506. At this time, the laser beam generator 2 is activated to make the cutting head 3 emit a laser beam to cut the tip of the acupuncture needle. After the cutting is completed, the counterclockwise rotation of the first gear 404 drives the second gear 701 to rotate clockwise, making the blocking seat 702 vertical. At this time, the blocking seat 702 will block the bottom of the vertical cutting head 3, thus achieving the purpose of safety during loading and unloading. Example 3

[0023] See Figures 5-8Based on Embodiment 1, a clamp 8 is provided above the loading platform 6. A gap is left between the clamping plate in the clamp 8 and the top of the loading platform 6. A cleaning component 9 is provided above the loading platform 6. The cleaning component 9 includes a support plate 901, which is fixedly connected to the top of the base plate 1. A reciprocating screw 902 is rotatably connected to the right side of the support plate 901. A screw nut 903 is threaded onto the outer surface of the reciprocating screw 902. The rotation of the reciprocating screw 902 can drive the screw nut 903 to move back and forth left and right. The screw nut 903 is fixedly connected to a connecting plate 904 below it. The connecting plate 904 is L-shaped and movably passes through the right side of the support plate 901. The left end of the connecting plate 904 is fixedly connected to a scraper 905 with a triangular cross-section. The scraper 905 is positioned in the space between the clamping plate in the fixture 8 and the loading platform 6. The scraper 905 movably fits against the top of the loading platform 6. When the scraper 905 slides on the loading platform 6, it can scrape off the slag on the loading platform 6. A connecting assembly 10 is provided on the right side of the lead screw 902. The connecting assembly 10 includes a bevel gear 101, specifically a spiral bevel gear 101. The bevel gear 101 is fixedly connected to the right end of the reciprocating lead screw 902. A limit shaft bracket 102 is rotatably connected to the right side of the bevel gear 101. The limit shaft bracket 102 is slidably connected to the outer surface of the rotating shaft 514. The limit shaft bracket 102 includes a bushing and a connecting post. The rotating shaft 514 is movably fitted inside the bushing on the limit shaft bracket 102. The limiting shaft bracket 102 is fixedly connected to the left side of the laser beam generator 2. The connecting assembly 10 also includes a face gear 103, which is fixedly connected to the outer surface of the rotating shaft 514. The face gear 103 meshes with the bevel gear 101 below. When the rotating shaft 514 descends, the bevel gear 101 will separate from the face gear 103. A collection box 11 is provided on the left side of the loading platform 6. The collection box 11 is used to collect molten slag. The collection box 11 is movably attached to the top of the base plate 1 and is placed on the base plate 1.

[0024] In practical use, as the rotating shaft 514 descends, it slides downward within the limiting shaft bracket 102. Simultaneously, the descent of the rotating shaft 514 also causes the face gear 103 to descend, disengaging it from the bevel gear 101. When slag removal is required after cutting, the hydraulic push rod 501 is activated to raise the lifting seat 502, causing the motor 513 to raise the rotating shaft 514. The rotating shaft 514 then engages the face gear 103 with the bevel gear 101, while simultaneously disengaging the first helical gear 515 on the rotating shaft 514 from the second... When the helical gear 407 meshes, the motor 513 is started to drive the rotating shaft 514 to rotate. The rotation of the rotating shaft 514 will drive the face gear 103 to rotate. The rotation of the face gear 103 will drive the bevel gear 101 to rotate. The rotation of the bevel gear 101 will drive the reciprocating screw 902 to rotate. The rotation of the reciprocating screw 902 will drive the screw nut 903 to move back and forth. The screw nut 903 will drive the connecting plate 904 to make the shovel bar 905 repeatedly shovel above the loading platform 6 and push the slag shoveled down into the collection box 11 for collection.

[0025] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
