In order to solve this technical problem, an automatic glass tube punching device is proposed.

[0031] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] Example 1 See also Figures 1 to 4, a structural diagram of an automatic glass tube punching device provided in Example 1 of the present invention, the automatic glass tube punching device comprises: a large combing machine 1 for conveying glass tubes and a punching mechanism; the large combing machine 1 for conveying glass tubes 2 to be punched, the punching mechanism comprises a front and rear adjustment component 3 arranged at the bottom, the output end of the front and rear adjustment component 3 is installed with a left and right sliding device 4, the output end of the left and right sliding device 4 is installed on a bottom mounting bracket 5, a lower lifting adjustment mechanism 6 is installed on the bottom mounting bracket 5, and an upper lifting adjustment mechanism 9 is installed on the output end of the bottom mounting bracket 5; an angle correction flipping mechanism 8 is installed at the output end of the upper lifting adjustment mechanism 9, and a punching gun component 7 is installed at the adjustment end of the angle correction flipping mechanism 8.

The front and rear adjustment components 3 are provided to realize the front and rear adjustment, and the left and right sliding devices 4 are provided to realize the left and right sliding adjustment; the lower lifting and adjusting mechanism 6 is installed at the output end of the left and right sliding devices 4 through the bottom mounting bracket 5, so that the glass tube positioning card plate does not collide with the glass tube transported by the glass tube combing machine when it moves with the left and right sliding devices 4, and the glass tube is positioned and fixed before punching; the distance from the punching gun component 7 to the glass tube is controlled by the upper lifting and adjusting mechanism 9, so as to realize the success rate of punching; the angle of the punching gun component 7 is conveniently adjusted by the angle correction and flipping mechanism 8, so as to realize the adjustment of the installation angle of the burner gun mounting base plate, and realize the angle between the punching burner on the punching burner and the axis of the glass tube, so as to try to realize that the axis of the burner and the axis of the glass tube are perpendicular when punching.

[0034] like Figure 2 As shown, as a preferred embodiment of the present invention, the front-back adjustment assembly 3 includes a welding base 31, an adjustment screw 32, a screw nut mounting plate 33 and a support rail 34; the two ends of the adjustment screw 32 are rotatably mounted on the welding base 31, the support rail 34 is fixedly mounted on the welding base 31, the adjustment screw 32 is arranged in parallel with the support rail 34, the nut on the screw nut mounting plate 33 is arranged through the adjustment screw 32, and the screw nut mounting plate 33 is slidably arranged on the support rail 34. The left-right sliding device 4 is installed on the screw nut mounting plate 33, so that the left-right sliding device 4 can move forward and backward to meet the process requirements for drilling holes in glass tubes of different lengths.

[0035] As a preferred embodiment of the present invention, the left and right sliding device 4 is installed on the screw nut mounting plate 33 on the front and rear adjustment component 3 by a set of servo-driven linear modules. Specifically, the left and right sliding device 4 includes a servo motor, a coupling, a slider guide assembly, a mounting seat plate and a slider mounting plate, which are prior arts and will not be introduced in detail here. The screw nut mounting plate 33 can be connected to the left and right sliding device 4 by bolts, and through servo drive, the accurate positioning of the glass tube punching and the glass tube conveying mechanism is realized. Because the glass tube is conveyed by a set of teeth on the large glass tube combing machine, the bottom mounting assembly of the punching machine is required to realize the accurate positioning of multiple glass tubes that need to be punched.

[0036] As a preferred embodiment of the present invention, the bottom mounting bracket 5 is mounted on the servo slider of the left and right sliding device 4 by bolts, so that the left and right sliding device 4 can drive the bottom mounting bracket 5 to move along with the glass tube 2 to be punched.

[0037] like Figure 3 As shown, as a preferred embodiment of the present invention, the bottom mounting bracket 5 includes a lower connecting plate 51, a lower lifting cylinder 52 and a lower mounting bracket 53, the lower connecting plate 51 is installed at the output end of the left and right sliding device 4, the lower mounting bracket 53 is installed on the left and right sliding device 4 through the lower connecting plate 51, and the lower lifting cylinder 52 is fixedly installed on the lower mounting bracket 53; the lower lifting cylinder 52 is also provided with a cylinder stroke adjustment device 54 to adjust the stroke of the lower lifting cylinder 52.

[0038] like Figure 3As shown, as a preferred embodiment of the present invention, the lower lifting and adjusting mechanism 6 includes a glass tube positioning plate 62; the glass tube positioning plate 62 is installed at the output end of the lower mounting bracket 53, and a glass tube positioning plate adjusting device 61 is also provided on the glass tube positioning plate 62. The glass tube positioning plate adjusting device 61 is also a prior art and will not be introduced in detail here. The glass tube positioning plate adjusting device 61 is provided to achieve fine adjustment of the upper and lower heights of the glass tube positioning plate 62 for different glass tube diameters. The cylinder stroke adjusting device 54 can achieve positioning adjustment for different glass tube diameters. The lower lifting and adjusting mechanism 6 is installed on the bottom mounting bracket 5. When the glass tube 2 to be punched is relatively still placed in the triangular groove on the glass tube positioning plate 62, the lower lifting cylinder 52 extends to drive the glass tube positioning plate 62 to lift the glass tube 2 to be punched, thereby achieving relative positioning and fixation of the glass tube. When a group of glass tubes is punched, the lower lifting cylinder 52 is retracted, driving the glass tube positioning plate 62 to drop and miss the unpunched glass tubes on the glass tube transmission large combing machine 1, and the left and right sliding device 4 drives the lower lifting adjustment mechanism 6 to enter the next group of glass tubes with holes, repeating the above actions to achieve the positioning of the glass tubes to be punched 2. The main components of the lower lifting adjustment mechanism 6 are the glass tube positioning plate 62 and the glass tube positioning plate adjustment device 61. The main function of the glass tube positioning plate adjustment device 61 is to achieve fine adjustment of the upper and lower heights of the glass tube positioning plate 62 for different glass tube diameters.

[0039] like Figure 4 As shown, as a preferred embodiment of the present invention, the upper lifting adjustment mechanism 9 includes an upper mounting bracket 91, a slider pressure plate 92, an upper lifting slider 94, a slider mounting seat 95 and an upper lifting guide rail 96; the upper mounting bracket 91 is mounted on the lower mounting bracket 53 of the bottom mounting bracket 5; the upper lifting guide rail 96 is mounted on the upper mounting bracket 91 for sliding up and down, the slider mounting seat 95 is mounted on the upper mounting bracket 91, the upper lifting slider 94 is mounted on the slider mounting seat 95, and an adjusting screw 93 is also provided between the slider mounting seat 95 and the upper lifting slider 94, and the upper lifting slider 94 is mounted on the upper mounting bracket 91 through the adjusting screw 93. The upper lifting guide rail 96 is mounted on the upper mounting bracket 91, mainly to provide a positioning guide for the lifting of the angle correction flipping mechanism 8.

[0040] like Figure 4As shown, as a preferred embodiment of the present invention, the angle correction flipping mechanism 8 includes a punching gun mounting seat 81, a side plate 82, a top mounting plate 83, an upper lifting cylinder 84 and an angle adjustment screw 85; the upper lifting cylinder 84 is fixedly mounted on the slider mounting seat 95, and the output end of the upper lifting cylinder 84 is connected to the top mounting plate 83, and side plates 82 are arranged on both sides of the top mounting plate 83, and the side plates 82 are installed on adjacent upper lifting guide rails 96. The two sides of one end of the punching gun mounting seat 81 are respectively rotatably mounted on the adjacent side plates 82, and the punching gun mounting seat 81 is arranged between the two side plates 82, and angle adjustment screws 85 are arranged on both sides of the other end of the side plate 82, and the angle adjustment screws 85 are arranged through the adjustment holes on the side plates 82, and the angle adjustment screws 85 are clearance-matched with the adjustment holes. In this way, the inclination angle of the punching gun mounting seat 81 can be adjusted by the angle adjustment screw 85. When the punching gun mounting seat 81 is adjusted to a suitable angle, the position of the punching gun mounting seat 81 is locked by rotating the angle adjustment screw 85.

[0041] As a preferred embodiment of the present invention, the punching gun assembly 7 is fixedly mounted on the punching gun mounting seat 81. The installation angle of the punching gun mounting seat 81 can be achieved by adjusting the angle adjustment screw 85, and the angle of the punching gun assembly 7 relative to the axial direction of the glass tube 2 to be punched can be achieved. The punching process requires that it needs to be as vertical as possible.

[0042] The working principle of the present invention is: The glass tube 2 to be punched is transferred to the punching position by the glass tube teeth on the glass tube conveying large combing machine 1, and the front and rear adjustment component 3 adjusts the front and rear position of the punching gun component 7 according to the different lengths of the glass tubes to meet the punching position requirements of the glass tube 2 to be punched. Usually, a row of multiple glass tubes 2 to be punched are conveyed on the glass tube conveying large combing machine 1. Because the glass tube conveying large combing machine 1 is a mechanism that moves forward at a uniform speed, but there is a relatively static distance between the punching gun component 7 and the glass tube 2 to be punched, the left and right sliding devices 4 are required to drive the punching gun component 7 to be relatively static and vertical to the top of the glass tube 7 to be punched. When the punching mechanism punches a group of glass tubes 2 to be punched (usually 3-6 tubes are a group, and the punching machine can achieve the requirement of punching 1-8 glass tubes at the same time) according to the process requirements, the left and right sliding devices 4 quickly move the punching gun component 7 to enter the next group of glass tubes 7 to be punched, and the cycle is repeated to achieve continuous punching of the glass tubes 2 to be punched.
