Description

Technical Field

[0001] This utility model relates to the technical field of leak prevention devices, and in particular to a leak prevention device for a corrosion-resistant tailstock screw. Background Technology

[0002] Etching machines in the plate-making industry and spray towers in the chemical industry, which operate in environments requiring spraying and atomization and rotary transmission, employ a leak-proof device on the tailstock screw of the etching machine. This device uses a rubber ring smaller than the screw diameter instead of the commonly used skeleton oil seal or O-ring for sealing and leak prevention, along with a double-layer protection with a water-slinging ring, to achieve the desired leak-proof effect. To check if the tailstock is properly tightened, the etching machine needs to move back and forth to provide an electrical signal (moving back and forth on the tailstock shaft would require wiring, which is inconvenient and prone to corrosion). Therefore, the movement is implemented on the screw.

[0003] However, existing corrosion machine tailstock screws commonly use skeleton oil seals and O-rings for leak prevention. Due to elasticity issues, excessive oscillation leads to a loss of sealing performance. Furthermore, the back-and-forth movement makes leakage more likely, resulting in corrosion of the wall and bearings. In view of this, we propose a leak prevention device for corrosion machine tailstock screws. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a leak-proof device for the corrosion-resistant tailstock screw.

[0005] The technical solution of this utility model is as follows: A leak-proof device for a corrosion-resistant tailstock screw rod, comprising a titanium screw rod, a front cover, a front rubber ring, a water-slinging ring, a rear rubber ring, and a plastic inner liner fitted on the outer surface wall of the titanium screw rod. A wall panel is provided on the side wall of the plastic inner liner, and a screw rod bearing seat is installed on the back wall of the wall panel. A bearing is provided inside the screw rod bearing seat, and a wall panel is installed on the open surface of the screw rod bearing seat. A proximity switch is installed on one side outer wall of the screw rod bearing seat. An iron ring is arranged at the end of the titanium screw rod, and a positioning ring is fitted on the outer surface wall of the titanium screw rod. A butterfly spring is connected to the side wall of the positioning ring.

[0006] Preferably, the front rubber ring is disposed between the front cover and the sleeve, and the two side walls of the front rubber ring are connected to the opposite side walls of the front cover and the sleeve.

[0007] Preferably, a sleeve is provided between the front rubber ring and the rear rubber ring, the rear rubber ring is disposed between the sleeve and the opposite wall of the plastic inner liner, and the two side walls of the rear rubber ring are connected to the sleeve and the opposite wall of the plastic inner liner.

[0008] Preferably, the water-spinning ring is disposed inside the sleeve, the water-spinning ring is sleeved on the outer surface wall of the titanium wire rod, and the outer surface wall of the water-spinning ring is connected to the inner surface wall of the sleeve.

[0009] Preferably, the bearing is sleeved on the titanium screw, and the outer surface wall of the bearing is connected to the inner surface wall of the screw bearing seat.

[0010] Preferably, a protruding cylinder is connected to one end of the titanium wire rod, and the iron ring is fitted onto the protruding cylinder.

[0011] Preferably, a support frame is connected to the side wall of the lead screw bearing seat, and a screw is connected to the bottom wall of the proximity switch, with a nut fitted onto the screw.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This invention utilizes the forward and backward movement of a titanium screw to move the front cover, front rubber ring, water-slinging ring, sleeve, rear rubber ring, and plastic inner liner. These components, in conjunction with the screw, contact the outer wall of the wall panel, sealing the other side of the wall panel. This reduces the risk of media entering the screw bearing seat, improves sealing performance in non-working states, and prevents media from corroding the internal structure of the wall panel. Furthermore, the position of the iron ring corresponds to the position of the proximity switch, further enhancing sealing performance during reset, thus achieving automatic detection of the protective effect.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example

[0018] like Figure 1As shown, the present invention proposes a corrosion prevention device for a tailstock screw, which includes a titanium screw 1, a front cover 2 located at the opening of a sleeve 5, and a front rubber ring 3 disposed between the front cover 2 and the sleeve 5, such that the two side walls of the front rubber ring 3 are fixedly connected to the opposite side walls of the front cover 2 and the sleeve 5. The front rubber ring 3, the front cover 2 and the sleeve 5 are all sleeved on the outer surface wall of the titanium screw 1 and are not fixedly connected to the outer surface wall of the titanium screw 1. The front rubber ring 3 plays a role in improving the sealing. The water-spinning ring 4 is located inside the sleeve 5 and is sleeved on the outer surface wall of the titanium wire rod 1. The outer surface wall of the water-spinning ring 4 is fixedly connected to the inner surface wall of the sleeve 5, which plays an auxiliary role in the installation and positioning of the sleeve 5. The plastic inner liner 7 is located at the opening on the other side of the sleeve 5. The rear rubber ring 6 is set between the plastic inner liner 7 and the sleeve 5. The two side walls of the rear rubber ring 6 are fixedly connected to the opposite side walls of the sleeve 5 and the plastic inner liner 7, which further improves the sealing between the sleeve 5 and the plastic inner liner 7.

[0019] Furthermore, the wall panel 8 is located on the side wall of the plastic inner liner 7, and a first through hole is provided on the wall panel 8. One end of the titanium wire rod 1 passes through the first through hole to prevent the titanium wire rod 1 from moving back and forth. The opening surface of the screw bearing seat 11 is fixedly connected to the side wall of the wall panel 8. The bearing 9 is set inside the screw bearing seat 11, and the outer surface wall of the bearing 9 is connected to the inner surface wall of the screw bearing seat 11. The bearing 9 is sleeved on the outer surface wall of the titanium wire rod 1. The bearing 9 and the titanium wire rod 1 are connected by a gap, so that the inner surface wall of the bearing 9 and the outer surface wall of the titanium wire rod 1 are in a non-fixed connection state.

[0020] Furthermore, the butterfly spring 10 is sleeved on the titanium screw 1 and is not connected to the outer surface wall of the titanium screw 1. One end of the butterfly spring 10 is located on the inner surface of the screw bearing seat 11, and the other end is located on the side wall of the positioning ring fixedly sleeved on the outer surface wall of the titanium screw 1. One end of the butterfly spring 10 is connected to the side wall of the inner surface of the screw bearing seat 11, while the other end of the butterfly spring 10 is also connected to the side wall of the positioning ring. This facilitates the movement of the positioning ring with the assistance of the butterfly spring 10. The positioning ring is not connected to the inner surface wall of the titanium screw 1 and is located on the side wall of the inner ring structure of the bearing 9, which helps to hold the inner ring structure of the bearing 9 and improve the stability of the inner ring structure of the bearing 9.

[0021] Furthermore, a sealing sliding hole is provided on the side wall of the lead screw bearing seat 11, one end of the titanium lead screw 1 passes through the sealing sliding hole, and the end of the titanium lead screw 1 is fixedly installed on the protruding cylinder. The iron ring 12 is fixedly sleeved on the outer surface wall of the protruding cylinder. The support frame is located on the outside of the lead screw bearing seat 11. The lead screw bearing seat 11 is L-shaped, and the vertical structure outer wall of the lead screw bearing seat 11 is fixedly connected to the side wall of the lead screw bearing seat 11. The proximity switch 13 is located on the horizontal structure of the support frame. The horizontal structure of the support frame has a positioning hole. A screw is fixedly connected to the bottom of the proximity switch 13. The bottom end of the screw passes through the positioning hole opened on the horizontal structure of the support frame. The nut is located below the horizontal structure of the support frame and is also sleeved on the screw for mounting and positioning the proximity switch 13.

[0022] In this embodiment, the movement of the titanium screw 1 causes the sleeve 5 to move using the water-spinning ring 4. Since the front cover 2, front rubber ring 3, rear rubber ring 6, and plastic inner liner 7 are all fixedly installed on both sides of the sleeve 5, the plastic inner liner 7 can contact the side wall of the wall panel 8 under the action of the titanium screw 1, thereby achieving the purpose of sealing the opening of the titanium screw 1. This achieves sealing protection for the opening of the wall panel 8 and the inside of the screw bearing seat 11, reducing the risk of the medium entering the opening of the wall panel 8 and the screw bearing seat 11, preventing the medium from corroding and damaging the internal structure of the wall panel 8 and the screw bearing seat 11, and further improving the protection effect on the bearing 9. At the same time, the movement of the iron ring 12 allows the proximity switch 13 to detect the position of the iron ring 12, which is beneficial for detecting the clamped and sealed state of the wall panel 8.

[0023] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
