Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] A purging device for a gun barrel bearing part includes a support base 24 and a support frame 40, which are mounted on a mounting plate. A support plate 26 is mounted on the upper end of the support base 24. The support plate 26 has a lower workpiece positioning groove and a drain groove. The lower workpiece positioning groove is used to position the lower end of the workpiece. A slag box 25 is placed inside the support base 24. The slag box 25 is located below the support plate 26 and corresponds to the drain groove. The drain groove is used to collect the slag generated during purging. A square shell 28 is mounted on the support plate 26. The upper end of the square shell 28 is open and surrounds the lower workpiece positioning groove and the drain groove from all sides. The support frame 40 has a vertical track, on which a purge slide 37 slides. A purge servo cylinder 38 is mounted on the support frame 40, and its piston rod is connected to the purge slide 37. The purge servo cylinder 38 drives the purge slide 37 to slide up and down. A linear cylinder 36 is mounted horizontally on the purge slide 37, and a transition seat 30 is mounted on its piston rod. The linear cylinder 36 drives the transition seat 30 to extend and retract horizontally. The transition seat 30 is L-shaped. A (fixed) recoil guide sleeve 32 is erected on the flat plate. A recoil guide rod 31 is slidably fitted inside the recoil guide sleeve 32. A tension spring limiting plate 33 is fixed at the upper end of the recoil guide rod 31. A tension spring connecting screw 34 is provided on the tension spring limiting plate 33. A shaft pin is erected on the flat plate of the transition seat 30. A recoil spring 35 is connected between the tension spring connecting screw 34 and the shaft pin. Under normal conditions, the lower surface of the tension spring limiting plate 33 contacts the top surface of the vertical plate of the transition seat 30, limiting the lower limit position of the tension spring limiting plate 33. At this time, the recoil spring 35 is stretched and deformed to provide preload. A square blowing box cover 29 is fixed to the lower end of the reciprocating guide rod 31. The square blowing box cover 29 is used to cooperate with the square shell 28 to close the square shell 28 and prevent material residue from flying out during the blowing process. The upper workpiece positioning groove is provided on the inner side of the top wall of the square blowing box cover 29. The upper workpiece positioning groove is used to position the upper end of the workpiece. An air guide pipe 27 is erected on the plate of the transition seat 30. The lower end of the air guide pipe 27 extends downward into the interior of the square blowing box cover 29. The lower end of the air guide pipe 27 is used to extend into the inner hole of the workpiece for blowing. The upper end of the air guide pipe 27 is used to connect to the air source. After the square blowing box cover 29 moves downward to abut the upper end of the workpiece, the tension spring limiting plate 33 moves upward to disengage from the top wall of the vertical plate of the transition seat 30, and the reciprocating spring 35 is further stretched and deformed.

[0012] The square blow molding box cover 29 is able to be placed on the square housing 28 and removed through horizontal and vertical movements. The trough consists of multiple fan-shaped troughs distributed on the inner and outer sides of the workpiece positioning groove.

[0013] Specifically: The purging module 4 includes a support base 24, a slag box 25, a support plate 26, an air guide pipe 27, a square shell 28, a square slag box cover 29, a transition seat 30, a return guide rod 31, a return guide sleeve 32, a tension spring limiting plate 33, a tension spring connecting screw 34, a return spring 35, a linear cylinder 36, a purging slide 37, a purging servo electric cylinder 38, an L-shaped connecting block 39, and a support frame 40. This module mainly completes the purging of the inner hole of the workpiece, ensuring the cleanliness of the inner hole and providing a guarantee for the accuracy of the test results. The slag box 25 is placed in the support base 24, which is convenient for disassembly and cleaning of the residue and oil in the box. The upper end of the slag box 25 is close to the support plate 26. The support plate 26 has upper and lower workpiece positioning grooves and a fan-shaped drainage groove to facilitate positioning and the outflow of residue. At the same time, the square shell 28 is connected to the support plate 26 by a shaft pin to prevent residue and oil from splashing around during the purging process. The top of the square housing 28 has a square blowing box cover 29. There is a workpiece positioning groove on the inner end face of the cover. At the same time, there are return guide rods 31 connected in the grooves on both sides of the outer end face of the cover. The other end of the return guide rod 31 is embedded in the limiting groove of the tension spring limiting plate 33 and is connected by bolts. The return guide rod 31 passes through the return guide sleeve 32 and the transition seat 30 and connects to the square blowing box cover 29. The center of the transition seat 30 is connected to the air guide tube 27 and passes into the square blowing box cover 29. One end of the return spring 35 is connected to the tension spring connecting screw 34, and the other end is connected to the shaft pin of the transition seat 30. One spring is distributed symmetrically on the left and right sides. When the servo cylinder 38 drives the transition seat 30 downward, the two recoil springs 35 are pulled downward, causing the recoil guide rod 31 and the tension spring limiting plate 33 to move vertically downward (the recoil guide rod 31, within the recoil guide sleeve 32, prevents the recoil springs 35, tension spring limiting plate 33, and recoil guide rod 31 from swinging). This, in turn, causes the square blow box cover 29 to move downward together until the workpiece enters the upper workpiece positioning groove on the inner end face of the cover. The recoil springs 35 ensure, on the one hand, that the workpiece is tightly attached to the positioning groove, preventing circumferential movement of the workpiece's inner hole during cleaning, and on the other hand, prevent damage to the workpiece or equipment due to excessive downward movement of the servo cylinder. This invention automates the cleaning of gun barrel parts and is currently used as a pre-processing step in the automated inspection of gun barrel parts.

[0014] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
