Description

Technical Field

[0001] This utility model relates to the technical field of dual-station tapping machines, specifically a dual-station tapping machine with a protective structure. Background Technology

[0002] A dual-head tapping machine is an industrial device used for efficient internal thread processing. Its core feature is its ability to operate simultaneously at two stations. A search revealed a dual-station tapping machine in patent publication CN222307597U. This machine requires clamping two workpieces and then simultaneously tapping them using two tapping heads. After tapping, the workpieces are removed, and the process is repeated with a new workpiece. This method does not allow for material preparation during the tapping process, resulting in low tapping efficiency. Furthermore, the tapping process easily generates flying debris, which not only contaminates the operating environment but also poses safety hazards to operators. Therefore, a dual-station tapping machine with a protective structure is designed to facilitate material preparation during the tapping process, further improving tapping efficiency. It also allows for easy covering of the tapping area and collection of tapped debris. Summary of the Invention

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] Please see Figure 1-7 A dual-station tapping machine with a protective structure includes an operating table 1 with two chip outlets. Each of the two chip outlets has a simultaneously lifting and lowering arc-shaped tapping cover 2 on its opposite side. A tapping mechanism is horizontally arranged on the arc-shaped tapping cover 2. A self-rotating dual-station clamping structure is arranged on the outer side of each of the two chip outlets. The dual-station clamping structure includes two arc-shaped clamping covers 24 fixedly connected by a rotating frame 23. Each arc-shaped clamping cover 24 has a clamping mechanism and a self-rotating mechanism that drives the rotating frame 23 to rotate. A top cover 6 is fixedly connected to the top of the arc-shaped tapping cover 2. The arc-shaped tapping cover 2, the arc-shaped clamping cover 24, and the top cover 6 form a protective structure that covers the top of the chip outlets. A chip collection structure communicating with the bottom of the two chip outlets is also provided at the bottom of the operating table 1.

[0026] Specifically, the clamping mechanism includes two symmetrically arranged clamping blocks 25. One clamping block 25 is fixedly mounted on the arc-shaped clamping cover 24, and the other clamping block 25 is connected to the arc-shaped clamping cover 24 through a clamping drive cylinder 26. A guide post 27 is fixedly mounted on one of the clamping blocks 25 to guide and slide with the other clamping block 25. The guide post 27 facilitates the clamping of the workpiece by the two clamping blocks 25. The guide post 27 also facilitates the guidance and support of the two clamping blocks 25 after clamping, thereby increasing the stability of the overall structure.

[0027] Specifically, the self-rotating mechanism includes a support frame 21 fixedly installed on the operating table 1. A rotary motor 22 that drives the rotating frame 23 to rotate is fixedly installed on the support frame 21. When the rotary motor 22 is started, the output shaft of the rotary motor 22 rotates 180 degrees clockwise or counterclockwise, thereby driving the two arc-shaped clamping covers 24 to change positions.

[0028] Specifically, the tapping mechanism includes a U-shaped frame fixedly mounted on the arc-shaped tapping cover 2. A tapping feed drive cylinder 4 is fixedly mounted on the U-shaped frame. A tapping motor housing 5, which is sealed and slidably fitted with the arc-shaped tapping cover 2, is fixedly mounted on the output shaft of the tapping feed drive cylinder 4. A tapping head 3 is rotatably connected to the tapping motor housing 5 through the tapping motor. Starting the tapping motor facilitates the rotation of the tapping head 3. The setting of the tapping motor housing 5 facilitates the protection of the tapping motor and improves the sealing performance of the arc-shaped tapping cover 2. The tapping feed drive cylinder 4 facilitates the horizontal feeding movement of the tapping motor housing 5 and the tapping head 3 towards the workpiece.

[0029] Specifically, it also includes a lifting mechanism for adjusting the height of the two arc-shaped tapping covers 2. The lifting mechanism includes a support frame 7 fixedly installed on the operating table 1. A lifting frame 8, which is fixedly connected to the two arc-shaped tapping covers 2, is vertically guided and slidably fitted on the support frame 7. A lifting drive cylinder 9, whose output end is fixedly connected to the lifting frame 8, is vertically fixedly installed on the support frame 7. The lifting drive cylinder 9 facilitates the lifting operation of the lifting frame 8 and the two arc-shaped tapping covers 2 as a whole. The overall stability is improved by the guide sliding cooperation between the lifting frame 8 and the support frame 7. Furthermore, the tapping feed drive cylinder 4, the lifting drive cylinder 9, and the clamping drive cylinder 26 are all hydraulically driven or pneumatically driven, preferably hydraulically driven.

[0030] Specifically, the chip collection structure includes an exhaust fan 13 fixedly installed at the bottom of the operating table 1 via a placement frame 11. Chip guide sleeves 10 are fixedly installed at the bottom of each of the two chip outlets. Chip receiving cylinders 12 are placed on the placement frame 11 below each of the two chip guide sleeves 10. A limiting mechanism is provided on each chip guide sleeve 10 to limit the movement of the chip receiving cylinder 12. The input end of the exhaust fan 13 is fixedly connected to the two chip guide sleeves 10 via an exhaust duct network 15. The exhaust duct network 15 and the chip guide sleeves 10... A filter screen 14 is fixedly installed at the through-hole. By starting the exhaust fan 13, the debris is easily drawn down from the top of the chip outlet through the exhaust pipe network 15 and filtered by the filter screen 14, so that it is retained in the chip guide sleeve 10. After tapping is completed, the exhaust fan 13 can be turned off, and the debris falls into the chip collection cylinder 12. The chip collection cylinder 12 placed below the chip guide sleeve 10 is easily limited by the setting of the limiting mechanism to prevent it from moving during the chip collection process and causing the debris to run out.

[0031] Specifically, the limiting mechanism includes a retaining ring 16 that can slide vertically with the chip collection cylinder 12. A fixing plate 17 is fixedly installed on the chip guide sleeve 10. A guide slide post 18 that is fixedly connected to the retaining ring 16 is slidably fitted on the fixing plate 17. A limiting block 20 is fixedly installed on the top of the guide slide post 18. A compression spring 19 is sleeved on the guide slide post 18. The two sides of the compression spring 19 are fixedly connected to the fixing plate 17 and the retaining ring 16, respectively. The compression spring 19 allows the retaining ring 16 to have a downward pushing force, which can cover and position the chip collection cylinder 12 placed under the chip guide sleeve 10. When the chip collection cylinder 12 needs to be removed, the retaining ring 16 can be pushed upward under the action of the spring 19, so that the retaining ring 16 is completely moved out of the top of the chip collection cylinder 12. Then the chip collection cylinder 12 can be moved away from the bottom of the chip guide sleeve 10, which makes it easy to pour out the chips collected in the chip collection cylinder 12.

[0032] In operation, two operators are positioned on either side, simultaneously clamping the workpiece onto the outer clamping mechanism. The workpiece is then rotated to the chip outlet using a self-rotating dual-station clamping structure. Two arc-shaped tapping covers 2 are simultaneously lowered to the arc-shaped clamping cover 24, and the tapping mechanism and the clamped workpiece are covered above the chip outlet by the arc-shaped tapping cover 2, tapping feed drive cylinder 4, and top cover 6. The tapping mechanism is then activated to tap the workpiece. Simultaneously, the chip collection structure collects chips. Meanwhile, the operators on both sides continue to clamp the workpiece onto the outer clamping mechanism. After the previous tapping cycle is completed, the two arc-shaped tapping covers 2 are raised, and the two dual-station clamping structures rotate, moving the clamped workpiece to the chip outlet. This process is repeated. The operators can then remove the tapped workpiece and proceed with material preparation.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
