Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a flexible tapping machine for machining. Background Technology

[0002] Tapping machines are among the most common machining equipment. They can machine internal threads and screws on the inner surfaces of holes in various parts such as machine housings, equipment end faces, nuts, and flanges, using through holes or blind holes of different specifications. Tapping machines are divided into rigid and flexible types. Rigid tapping is mainly used in CNC machining centers and other equipment with precise synchronous feed functions to meet the needs of high-speed machining. Rigid tapping relies entirely on the rigidity of the metal support and has no buffer. It has a high cutting speed and can be re-tapping after machining, but it is prone to tool breakage. Flexible tapping uses a floating telescopic tool holder. The elastic device of the flexible tap tool holder can replenish the feed of the tap in time, which can effectively protect the tap from breaking. However, the speed is slow and it cannot be re-tapping.

[0003] A search revealed Chinese Patent Publication No. CN220533152U, which discloses a flexible tapping machine. The machine includes a support device for supporting and extending the tapping mechanism. A drive device for driving and flexible tapping is installed on the top of the support device. The machine also includes a tapping device installed at the bottom of the drive device for three-part tapping and for adjusting the tapping diameter by sliding centripetally. The tapping device includes a mounting handle, and a tapping head is slidably mounted on the bottom of the mounting handle.

[0004] After tapping, debris may adhere to the outer wall of the tap tip. If not cleaned in time, it may affect the accuracy of the next tapping operation. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5 As shown, a flexible tapping machine for machining includes a worktable 1. A chip collection groove is provided on the top of the worktable 1, and a placement groove is provided on the rear side of the worktable 1. The placement groove is connected to the chip collection groove, and a collection box 6 is placed in the placement groove. A pull ring is fixedly connected to the rear side of the collection box 6. An clearance hole 101 is provided on the top of the worktable 1. A frame 2 is bolted to the top of the worktable 1. Two sets of clamping assemblies are symmetrically arranged on the side of the frame 2 that are close to each other. The clamping assembly includes a first hydraulic cylinder 301 fixedly connected to the side wall of the frame 2. A clamping plate 302 is fixedly connected to one end of the first hydraulic cylinder 301.

[0026] A tapping mechanism is provided above the workbench 1. The tapping mechanism includes a tapping head 406 and a second hydraulic cylinder 401 fixedly connected to the top of the frame 2. A mounting plate 402 is fixedly connected to the bottom of the second hydraulic cylinder 401. A rotary motor 403 is bolted to the bottom of the mounting plate 402. A horizontal plate 404 is fixedly connected to the output end of the rotary motor 403. A tool holder 405 is fixedly connected to the bottom of the horizontal plate 404. The tapping head 406 is connected inside the tool holder 405. The tool holder 405 adopts a floating telescopic tool holder commonly used on tapping machines.

[0027] A cleaning mechanism is provided on the frame 2. The cleaning mechanism includes an electric push rod 501 fixedly connected to the side wall of the frame 2. A vertical plate 502 is fixedly connected to the movable end of the electric push rod 501. Two mounting strips 503 are fixedly connected to the side of the vertical plate 502 near the tapping head 406. The mounting strips 503 are elastic and are arranged one after the other. The tapping head 406 is located between the two mounting strips 503. A brush plate 504 is fixedly connected to the side of the two mounting strips 503 that are close to each other. Several bristles are fixedly connected to the brush plate 504. The brush plate 504 is located at the end of the mounting strip 503 near the tapping head 406.

[0028] The cleaning mechanism also includes an auxiliary component for scraping away debris trapped in the bristles. The auxiliary component includes a mounting block 506, which is V-shaped with its tip facing the tapping head 406. When the brush plate 504 is squeezed by the mounting block 506, the ends of the two mounting strips 503 move away from each other and undergo elastic deformation, which facilitates the falling of debris between the two brush plates 504. The mounting block 506 is fixedly connected to the frame 2 by a connecting bracket 505. Several scraping teeth 507 are fixedly connected to the front and rear side walls of the mounting block 506. The brush plate 504 and the mounting block 506 are distributed on both sides of the tapping head 406, and the scraping teeth 507 scrape away the debris trapped in the bristles.

[0029] Working principle: In use, place the workpiece on top of the worktable 1, aligning the tapping position of the workpiece with the clearance hole 101. Control the first hydraulic cylinder 301 to clamp the workpiece with the two clamping plates 302. Start the rotary motor 403, which drives the horizontal plate 404 to rotate the tool holder 405 and the tapping head 406. Then, control the second hydraulic cylinder 401 to move the tapping head 406 downward. After the tapping head 406 contacts the workpiece, tapping begins. After tapping is completed, turn off the rotary motor 403. Control the second hydraulic cylinder 401 to move the tapping head 406 upward to the initial height. Control the first hydraulic cylinder 301 to release the workpiece with the clamping plates 302, and remove the workpiece. Control the electric push rod 501 to drive the vertical plate 502. The mounting strip 503 moves, and the brush plate 504 on the mounting strip 503 cleans the debris around the tapping head 406 to avoid affecting the accuracy of the next tapping. The mounting strip 503 continues to move. When the brush plate 504 is squeezed by the mounting block 506, the ends of the two mounting strips 503 move away from each other and undergo elastic deformation, which makes it easier for the debris between the two brush plates 504 to fall off. The bristles on the brush plate 504 and the scraping teeth 507 on the mounting block 506 interweave with each other. The scraping teeth 507 scrape off the debris trapped in the bristles. Then, by controlling the electric push rod 501, the vertical plate 502 drives the mounting strip 503 to reset. When tapping again, the bottom of the workpiece is pushed from front to back against the worktable 1, and the debris cleaned on the worktable 1 is pushed into the collection box 6.
