Description

Technical Field

[0001] The utility model belongs to the technical field of glass production equipment and relates to a set tool for a rubber ring on a glass transmission roller. Background Art

[0002] In glass production, transmission rollers are needed to transport glass to various branches. The rubber rings of the rollers are mostly made of rubber. During long-term use, the rubber rings will age, wear, twist and deform, causing the glass to jump or even deviate during transmission. At this time, it is very costly to replace the entire roller. If the roller body itself is not deformed, the roller can be repaired by replacing the rubber ring. The traditional way is to cut off the old rubber ring, first install the new rubber ring on a conical sleeve. There is a 1mm step at the end of the conical sleeve. After it is put into the head of the conical fixture, a clamping device with a circular ring is used to press the rubber ring into the fixture. Finally, the entire fixture is put on the roller, and then the rubber ring is knocked out of the fixture and put on the roller. Then it is knocked to the installation position where glue has been applied.

[0003] Existing technical problems:

[0004] Since the inner diameter of the rubber ring is smaller than the outer diameter of the tapered clamp, the process of pressing the rubber ring from the tapered sleeve to the head of the tapered clamp is very difficult and requires very large and uniform force. Once too much force is used, the rubber ring may be deformed and damaged and become unusable. Utility Model Content

[0005] The purpose of the present invention is to provide a set tool for rubber rings on glass conveying rollers in response to the above-mentioned problems existing in the existing technology. The technical problem to be solved by the present invention is how to make the installation operation of the rubber rings on the glass conveying rollers easier.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a set tool for a rubber ring on a glass transmission roller, the glass transmission roller includes a roller body and a mounting short shaft located at the end of the roller body, the diameter of the mounting short shaft is smaller than the diameter of the roller body, and is characterized in that the set tool includes a positioning cylinder that can be sleeved on the short shaft and a cylinder body slidably connected to the outside of the positioning cylinder, the inner end of the cylinder body has a support cylinder with an outer diameter greater than the diameter of the roller body, the inner end of the support cylinder has a guide cylinder, the guide cylinder includes a plurality of fins, the fins and the guide cylinder are connected by an elastic member, each fin can be enclosed into a tapered cylinder with the small diameter end facing the roller body, and the support cylinder is externally threaded with a pushing disk.

[0007] Furthermore, a liquid cavity is formed between the cylinder body and the positioning cylinder, and the positioning cylinder has a connecting pipe connected to the liquid cavity. The connecting pipe is connected to a hydraulic pump, and the hydraulic pump can control the relative movement of the cylinder body and the positioning cylinder by extracting the hydraulic oil in the liquid cavity or supplying hydraulic oil into the liquid cavity.

[0008] This solution aims to more easily fit the rubber ring on the roller body. Specifically, the rubber ring is first inserted from the small diameter end of the guide cylinder and squeezed to the support cylinder. At this time, the positioning cylinder can be controlled not to exert squeezing force on the fins, and the fins are in a state that can easily bend inward at the elastic member. After the rubber ring is fitted, the positioning cylinder is fitted on the mounting short shaft and the positioning cylinder is pressed until the fins are almost close to the end face of the roller body. Subsequently, the positioning cylinder and the cylinder body are controlled to approach each other so that the positioning cylinder squeezes the fins, causing the conical cylinder structure composed of the fins to gradually tend to a cylindrical shape. At this time, the rubber ring can be supported inward to a state where the diameter is larger than the outer diameter of the roller. Finally, the pushing disk is rotated to move the rubber ring on the support cylinder, thereby realizing the transfer of the rubber ring from the support cylinder to the roller body, until the rubber ring is almost on the roller body, completing the fitting of the rubber ring on the roller body. Afterwards, the position of the rubber ring on the roller body can be adjusted by using other tools. The relatively difficult step of supporting the rubber ring outward to fit it on the roller body can be achieved by this tool. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0012] like Figure 1 The set tool shown in the figure, the glass transmission roller includes a roller body 1 and a mounting short shaft 2 located at the end of the roller body 1, the diameter of the mounting short shaft 2 is smaller than the diameter of the roller body 1, the set tool includes a positioning cylinder 3 that can be sleeved on the short shaft and a cylinder body 4 slidably connected to the outside of the positioning cylinder 3, the inner end of the cylinder body 4 has a support cylinder 5 with an outer diameter larger than the diameter of the roller body 1, the inner end of the support cylinder 5 has a guide cylinder, the guide cylinder includes a plurality of fins 6, the fins 6 and the guide cylinder are connected by an elastic member 7, the elastic member 7 is a thin area between the fins 6 and the guide cylinder, which is made of metal, each fin 6 can be enclosed into a conical cylinder with the small diameter end facing the roller body 1, and the support cylinder 5 is externally threaded with a pushing disk 8.

[0013] A liquid chamber 9 is formed between the cylinder body 4 and the positioning cylinder 3. The positioning cylinder 3 has a pipe connected to the liquid chamber 9. The pipe is connected to a hydraulic pump. The hydraulic pump can control the relative movement of the cylinder body 4 and the positioning cylinder 3 by extracting or injecting hydraulic oil into the liquid chamber 9. In other words, the relative movement between the cylinder body 4 and the positioning cylinder 3 is driven by hydraulic means.

[0014] This solution is designed to easily fit the rubber ring 10 on the roller body 1. Specifically, first insert the rubber ring 10 from the small diameter end of the guide cylinder and squeeze it to the support cylinder 5. At this time, the positioning cylinder 3 can be controlled not to exert pressure on the fin 6, and the fin 6 is in a state that can be easily bent inward at the elastic member 7. After the rubber ring 10 is fitted, the positioning cylinder 3 is fitted on the mounting short shaft 2 and pressed until the fin 6 is almost close to the end face of the roller body 1. Subsequently, the positioning cylinder 3 and the cylinder body 4 are controlled to move closer to each other so that the positioning cylinder 3 squeezes the fin 6, resulting in the fin 6 forming a The conical structure gradually tends to be cylindrical. At this time, the rubber ring 10 can be supported inwardly to a state where the diameter is larger than the outer diameter of the roller body 1. Finally, the pushing disk 8 is rotated to move the rubber ring 10 on the support tube 5, thereby realizing the transfer of the rubber ring 10 from the support tube 5 to the roller body 1, until the rubber ring 10 is almost located on the roller body 1, completing the sleeve installation of the rubber ring 10 on the roller body 1. Afterwards, the position of the rubber ring 10 on the roller body 1 can be adjusted by using other tools. The relatively difficult step of supporting the rubber ring 10 outwardly to sleeve it on the roller body 1 can be achieved by this tool.
