Abstract
The utility model relates to a ceramic tube for sleeving, which is used for fixing a pin when in sealing of the pin in a color glass screen production line. The ceramic tube is in a cap structure, while the outer diameter of a joint position of the ceramic tube with a pin is larger than those of other portions of the ceramic tube, the outer diameter of the joint position of the ceramic tube with the pin is increased by 1mm to 4mm, the inner diameters of other portions of the ceramic tube are reduced to increase wall thickness, the wall thickness reaches 2mm-4mm, and a lead angle of 26 +/- 1 degrees is arranged at the inner-diameter position of the ceramic tube on the joint face of the ceramic tube with the pin. Therefore, the ceramic tube has the advantages of low data fluctuation of the inner face of a glass screen, long replacement cycle, reduced possibility of batch defective glass screens, and relieved labor intensity.
Description
Technical field
The used suit earthenware of fixing pin when the utility model relates in a kind of colored glass screen production line the sealing-in pin.
Background technology
When the pin sealing-in, supply with glass screen pin by the earthenware of pin machine, because earthenware often is in the condition of high temperature (more than 1000 ℃), the comparison fragility of change fractures easily, in addition, there is chamfering in pin at head and shoulder joint.There are the following problems for earthenware originally:
1. the chamfering at end fixing pin place is below 25 °, and the degree of depth is more shallow less than 1mm, and it is unstable that pin shoulder and earthenware are engaged, and directly has influence on pin sealing temperature and glass screen data stability.
2. the earthenware inner chamber is too big, is 6mm, makes that its body tube wall is too thin, has only 1.9mm, fractures easily, and fixing pin place, end is thinner simultaneously, and is very easily damaged.
Particularly earthenware is used to a certain degree, all the more so behind the oxide of appearance adhesion, just because of above-mentioned 2 points, cause the frequent replacing of earthenware needs,, and in the replacing process, cause accident in batches easily because the earthenware cost is higher, so, if can there be a kind of sealed state stable, the life-span, long earthenware updated, and can improve the sealing-in quality greatly and reduced production costs.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of glass screen inner face data fluctuations little, and the replacement cycle is long, reduces the glass screen probability of defective in batches, the suit earthenware that reduces labor intensity.
The technical scheme that its technical problem that solves the utility model adopts is: earthenware is a kind of earthenware and the dowelled joint place external diameter cap-like structure greater than earthenware other parts external diameter.Described earthenware cap-like structure is: at earthenware and dowelled joint place thickening earthenware external diameter, its diameter increases 1-4mm, in the earthenware other parts, reduces internal diameter to increase wall thickness, and thickness reaches 2-4mm.On earthenware and dowelled joint face, be provided with lead angle at earthenware internal diameter position, its angle is 26 ± 1 °, the degree of depth is 1.0--5mm.The force part is thickeied processing: at earthenware and dowelled joint place, adopt the way that increases the pin external diameter, make its diameter increase 1-4mm, in the earthenware other parts, employing reduces internal diameter to increase the way of wall thickness, make thickness reach 2-4mm,, make the earthenware integral thickness increase by above way.On earthenware and dowelled joint face, at earthenware internal diameter position, design an enough big lead angle, its angle is 26 ± 1 °, the degree of depth is 1.0--5mm, make present various pin shoulder can both with the earthenware fluid-tight engagement.
The utlity model has following good effect:
1. a suit earthenware by increase the way of internal diameter, external diameter respectively at different parts, increases the earthenware integral thickness, has reduced because of the damaged probability of changing of earthenware, and the life-span prolongs greatly.
2. by the unique lead angle of design, it is tightr to make that earthenware and pin shoulder engage, glass screen data are stable more and improved the sealing-in shape of pin, and it is bad and change the probability of earthenware according to shakiness or sealing-in shape to have reduced factor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model and dowelled joint schematic diagram.
Fig. 2 is the schematic diagram of suit earthenware on fastener of band pin.
Among the figure: 1, earthenware other parts external diameter, 2, internal diameter, 3, thickening earthenware external diameter, 4, the earthenware internal diameter, 5, lead angle, 6, earthenware, 7, pin, 8, fastener.
Embodiment
As shown in Figure 1, 2, earthenware of the present utility model is a kind of earthenware (6) and the cap-like structure of dowelled joint place external diameter (3) greater than earthenware other parts external diameter (1).Described ground earthenware cap-like structure is: at earthenware (6) and pin (7) joint (head) thickening earthenware external diameter (3), its diameter increases 1-4mm, at earthenware other parts (root), reduces internal diameter (2) to increase wall thickness, and thickness reaches 2-4mm.On earthenware and dowelled joint face, be provided with lead angle (5) at earthenware internal diameter (4) position, its angle is 26 ± 1 °, the degree of depth is 1.0--5mm.
The suit earthenware is fixed on its fastener (8), pin (7) is contained on the earthenware (6),, reduced damaged probability because this earthenware integral thickness increases; At earthenware internal diameter and pin binding site, design an enough big lead angle (5), make present various pin shoulder can both with the earthenware fluid-tight engagement, make data more stable, improved the grade of product.
Claims (3)
1. suit earthenware is characterized in that: earthenware is a kind of earthenware (6) and the cap-like structure of pin (7) joint external diameter greater than earthenware other parts external diameter (1).
2. a kind of suit earthenware according to claim 1, it is characterized in that: described earthenware cap-like structure is: at earthenware (6) and pin (7) joint thickening earthenware external diameter (3), its diameter increases 1-4mm, in the earthenware other parts, reduce internal diameter (2) to increase wall thickness, thickness reaches 2-4mm.
3. a kind of suit earthenware according to claim 1 is characterized in that: on earthenware (6) and pin (7) composition surface, be provided with lead angle (5) at earthenware internal diameter (4) position, its angle is 26 ± 1 °, and the degree of depth is 1.0--5mm.
