Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of mechanical processing equipment, and particularly relates to a brittle pipe thread groove milling device. BACKGROUND

[0002] Brittle pipe refers to a pipe that is prone to breakage when subjected to a certain impact or vibration. Common types include ceramic pipes. The pipe is moved to a milling machine for thread groove processing, then moved to a thread detector for detection, and finally moved to a discharge rack to complete the thread groove processing. When moving the pipe, a fixed clamping method is usually used. Common methods for clamping and fixing the pipe include three-jaw air cylinders and internal support chucks. The three-jaw air cylinder applies force from the outside to the inside of the pipe to keep it fixed. The internal support chuck applies force from the inside to the outside of the pipe to keep it fixed. Thread detectors are usually divided into internal thread detectors and external thread detectors, which detect internal and external threaded pipes, respectively.

[0003] The existing brittle pipe thread groove milling device generally uses a fixed clamping method for the pipe. When a three-jaw air cylinder is used to clamp a pipe with external threads, the external threads are easily damaged by direct extrusion from the three-jaw air cylinder. When an internal support chuck is used to clamp a pipe with internal threads, the internal threads are easily damaged by direct extrusion from the internal support chuck, reducing the quality of the thread groove. The device cannot conveniently switch between clamping and fixing methods, lacks convenience, and when detecting threads, the pipe is usually clamped and fixed in a specified position before being detected by the thread detector. After detection, the pipe needs to be clamped and moved to the discharge rack again. Multiple clamping of the pipe can cause the thread grooves on the pipe to be extruded and deformed, reducing the quality of the thread grooves and the reliability of the device. SUMMARY

[0064] Embodiment 2

[0065] Referring to Figures 1-21 , the second embodiment of the present application is based on the previous embodiment.

[0066] As Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 18 shown, the clamping mechanism 5 includes a rotating disc 501, a first driving source 502, a three-jaw cylinder a 503, a three-jaw cylinder b 504, a first inner support chuck 505 and a second inner support chuck 506, the rotating disc 501 is rotatably connected to the housing 3, the first driving source 502 is fixedly connected to the housing 3, the output end of the first driving source 502 is fixedly connected with the rotating disc 501, the three-jaw cylinder a 503, the three-jaw cylinder b 504, the first inner support chuck 505 and the second inner support chuck 506 are all fixedly connected to the rotating disc 501.

[0067] It should be noted that the three-jaw cylinder a 503 and the three-jaw cylinder b 504 are of the same specification, and the first inner support chuck 505 and the second inner support chuck 506 are of the same specification.

[0068] According to the above structure, the first driving source 502 works to drive the output end to rotate the rotating disc 501, the rotating disc 501 drives the three-jaw cylinder a 503, the three-jaw cylinder b 504, the first inner support chuck 505 and the second inner support chuck 506 to rotate, which is convenient for the three-jaw cylinder a 503, the three-jaw cylinder b 504, the first inner support chuck 505 and the second inner support chuck 506 to rotate to the upper end of the rotating disc 501 to correspond to the clamping end of the moving mechanism 7, and is convenient for the three-jaw cylinder a 503, the three-jaw cylinder b 504, the first inner support chuck 505 and the second inner support chuck 506 to rotate to the lower end of the rotating disc 501 to correspond to the clamping end of the milling machine 1, thereby improving the convenience, the three-jaw cylinder a 503 and the three-jaw cylinder b 504 are used for clamping the inner threaded pipe, and the first inner support chuck 505 and the second inner support chuck 506 are used for clamping the outer threaded pipe, one of which fails to rotate the rotating disc 501 to switch to the other to continue to work, thereby avoiding the need to stop and replace due to a single failure, and improving the reliability.

[0069] As shown in Figure 2 , Figure 3 , Figure 6 and Figure 8 , the detection mechanism 6 includes a horizontal moving plate 601, an inner thread detector 602 and an outer thread detector 603, the horizontal moving plate 601 is slidingly connected to the housing 3, and the inner thread detector 602 and the outer thread detector 603 are fixedly connected to the horizontal moving plate 601.

[0070] It should be noted that the inner thread detector 602 and the outer thread detector 603 are arranged in the horizontal direction on the horizontal moving plate 601, the inner thread detector 602 is used for detecting the brittle pipe with inner threads, and the outer thread detector 603 is used for detecting the brittle pipe with outer threads.

[0071] According to the above mechanism, after the horizontal moving plate 601 slides on the housing 3, the horizontal moving plate 601 drives the inner thread detector 602 and the outer thread detector 603 to slide in the horizontal direction, so that the inner thread detector 602 or the outer thread detector 603 corresponds to the clamping end of the moving mechanism 7, thereby switching the thread detection type of the detection mechanism 6 on the machined pipe, facilitating the thread detection on the brittle pipe with inner threads or the brittle pipe with outer threads, improving the convenience and the efficiency of thread detection in the thread groove processing.

[0073] It should be noted that the cross-sectional shape of the first sliding groove 301 and the first sliding bar 6011 is T-shaped.

[0074] According to the above structure, the first sliding groove 301 cooperates with the first sliding bar 6011 to make the sliding process of the transverse plate 601 on the shell 3 more stable.

[0075] As shown in Figure 2 , Figure 3 , Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 18 and Figure 19 , one side of the transverse plate 601 is provided with a second driving source 604, which is fixedly connected to the shell 3.

The lower side of the first gear 605 is provided with a rack 606, which is fixedly connected to the transverse plate 601. The rack 606 is engaged with the first gear 605.

[0076] It should be noted that the rack 606 and the outer side of the first gear 605 are provided with a cover plate, which is fixedly connected to the transverse plate 601, for reducing the entry of dust and other impurities into the inside of the transverse plate 601 to cause damage to the rack 606 and the first gear 605.

[0077] According to the above structure, the second driving source 604 works and the output end drives the first gear 605 to rotate. The first gear 605 drives the transverse plate 601 to slide on the shell 3 through the rack 606, which facilitates the switching of the inner thread detector 602 or the outer thread detector 603 for thread detection of the pipe.

[0078] As shown in Figure 8 , Figure 9 , Figure 11 and Figure 19 , the inside of the transverse plate 601 is provided with a sliding hole 6012. One side of the first gear 605 is fixedly connected with a cylinder 6051. The sliding hole 6012 is in sliding cooperation with the cylinder 6051.

[0079] It should be noted that the sliding hole 6012 and the cylinder 6051 also rotate together.

[0080] According to the above structure, when the first gear 605 drives the transverse plate 601 to slide along the shell 3 through the rack 606, the first gear 605 and the transverse plate 601 move relatively. The cylinder 6051 cooperates with the sliding hole 6012 to make the relative movement between the first gear 605 and the transverse plate 601 more stable.

[0081] As shown in Figures 2-3 ,Figure 6 、 Figures 12-18 and Figures 20-21 As shown in FIGS. 7A and 7B, the moving mechanism 7 comprises a cover 701, a rotating block 702, a connecting plate 703, a lifting plate 704, a three-jaw cylinder c705 and a third inner support chuck 706. The cover 701 is fixedly installed on the sliding plate 4. The rotating block 702 is rotatably connected inside the cover 701. The connecting plate 703 is fixedly connected inside the rotating block 702. The lifting plate 704 is slidably connected inside the connecting plate 703. The three-jaw cylinder c705 and the third inner support chuck 706 are both fixedly connected on the lifting plate 704.

[0082] It should be noted that the upper portion of the cover 701 is threadedly connected with a check ring for preventing the rotating block 702 from moving upward out of the cover 701. A rectangular hole is formed in the rotating block 702, which is adapted to the outer wall of the connecting plate 703. The rotating block 702 is threadedly connected with the connecting plate 703. A circular hole is formed in the sliding plate 4, which is arranged below the rotating block 702. The diameter of the circular hole is smaller than the diameter of the rotating block 702 and larger than the diagonal of the rectangular hole.

[0083] As shown in FIGS. 7A and 7B, Figure 3 、 Figure 6 、 Figure 12 、 Figure 14 、 Figure 15 、 Figure 17 、 Figure 18 and Figure 20 The top of the connecting plate 703 is fixedly connected with a third driving source 707. The output end of the third driving source 707 is fixedly connected with a lead screw 708, which is rotatably connected with the lifting plate 704. The outer portion of the lead screw 708 is threadedly connected with a sliding block 709, which is fixedly connected with the lifting plate 704.

[0084] It should be noted that the lower end of the lead screw 708 is provided with a lead screw support seat, which is fixedly installed on the connecting plate 703 and rotatably connected with the lower end of the lead screw 708.

[0085] According to the above structure, when the third driving source 707 works, the output end drives the lead screw 708 to rotate on the connecting plate 703. The lead screw 708 drives the sliding block 709 to move up and down along the axis of the lead screw 708. The sliding block 709 drives the lifting plate 704 to slide up and down on the connecting plate 703. The lifting plate 704 drives the three-jaw cylinder c705 and the third inner support chuck 706 to move up and down on the sliding plate 4. Thus, the three-jaw cylinder c705 or the third inner support chuck 706 can be corresponded with the clamping mechanism 5 or the detection mechanism 6, so that the moving mechanism 7 can move the pipe between the clamping mechanism 5 and the detection mechanism 6.

[0086] AsFigure 3 , Figures 12-14 , Figures 16-18 , Figures 20-21 As shown, a fourth motor 710 is fixedly connected to the outside of the cover 701, and a second gear 711 is fixedly connected to the output end of the fourth motor 710. A third gear 712 is fixedly connected to the outside of the rotating block 702, and the third gear 712 meshes with the second gear 711.

[0087] It should be noted that the third gear 712 and the rotating block 702 are welded together.

[0088] According to the above structure, after the fourth motor 710 is working, the output end drives the second gear 711 to rotate. The second gear 711 drives the rotating block 702 to rotate inside the cover 701 through the third gear 712. The rotating block 702 drives the connecting plate 703 to rotate. The connecting plate 703 drives the lifting plate 704 to rotate inside the sliding plate 4, which facilitates the adjustment of the orientation of the three-jaw cylinder c705 and the third inner support chuck 706, facilitates the movement of the pipe at the loading rack 10 to the side close to the clamping mechanism 5, and facilitates the movement of the pipe from the detection mechanism 6 to the unloading rack 20.

[0089] like Figures 1-6 , Figure 12 , Figure 14 and Figure 18 As shown, a baffle 401 is fixedly connected to one side of the sliding plate 4, one end of the pneumatic telescopic rod 8 is fixedly connected to the baffle 401, and the other end of the pneumatic telescopic rod 8 is fixedly connected to the housing 3. A set of second slide bars 302 is fixedly connected to the top of the housing 3, and a set of second slide grooves 402 is opened at the bottom of the sliding plate 4. The second slide grooves 402 are slidably connected to the second slide bars 302.

[0090] It should be noted that the cross-sectional shape of the second slide 402 and the second slide bar 302 is T-shaped. The milling machine tool 1 is equipped with 3 housings. The three-axis gantry robot 2 is a double-arm three-axis gantry robot. The loading rack 10 is a double-layer pallet type material rack. The unloading rack 20 is a plastic mesh belt type material rack. A position sensor is installed on the unloading rack 20.

[0091] According to the above structure, the second slide groove 402 and the second slide bar 302 cooperate to make the sliding plate 4 slide on the housing 3 more stable.

[0092] The working principle of the present application is that the machined pipe is clamped on the milling machine 1, and the pipe to be processed is placed on the feeding rack 10. First, the pipe to be processed is moved to the clamping mechanism 5 by the moving mechanism 7, the clamping mechanism 5 exchanges the machined pipe and the pipe to be processed with the milling machine 1, the milling machine 1 processes the thread groove of the pipe to be processed, the machined pipe is moved to the detection mechanism 6 by the moving mechanism 7 to accept thread detection, and after detection, the machined pipe is moved to the discharging rack 20 by the moving mechanism 7. Then the moving mechanism 7 moves the next pipe to be processed on the feeding rack 10 to the clamping mechanism 5, so as to realize the thread groove processing of the brittle pipe with automatic feeding and discharging. In this process, the clamping mechanism 5 can switch the way of clamping and fixing the pipe, improve the convenience and the quality of the thread groove, the moving mechanism 7 can reduce the clamping times of the brittle pipe when detecting the thread, improve the quality of the thread groove, and the detection mechanism 6 can switch to internal thread detection or external thread detection, improve the efficiency of thread detection in thread groove processing.

[0093] It should be noted that the first driving source, the second driving source and the third driving source are motors, and specific selection can be made according to actual conditions.

[0094] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should be considered as the protection scope of the present application. The structures, devices and operation methods not specifically described and explained in the present application, such as without special description and limitation, are implemented according to the conventional means in the art.
