Abstract
The utility model provides a clamp for a biscuit of a ceramic discharge tube shell, which comprises a core rod (1), a fixed core rod seat (2), a movable core rod seat (3) and a rotary jaw (6), wherein two elastic rubber cushions (4, 5) are sleeved on the core rod (1); the movable core rod seat (3) comprises a sliding head (31) and an ejector pin seat (33) which are connected through a bearing (32); the ejector pin seat (33) is assembled with an ejector pin (7); one end of the core rod (1) is in interference fit or integrated with the fixed core rod seat (2); the other end of the core rod (1) is in clearance fit with the sliding head (31); and the rotary jaw (6) is connected with the end of the fixed core rod seat (2), which is not connected with the core rod (1). The clamp can be arranged on a small instrument lathe to clamp the biscuit to rotate together so as to avoid damage of clamping to the biscuit of the ceramic discharge tube shell and enable the biscuit to bear a centrifugal force which is generated due to high speed rotation, thereby avoiding crack caused by vibration and ensuring the ceramic biscuit to rotate at high speed without being damaged in the grinding process.
Description
Technical field
The utility model relates to a kind of anchor clamps of biscuit of ceramics, the anchor clamps of the tubular ceramic biscuit thick in the middle of a kind of more precisely clamping, that two ends are thin.
Background technology
Alumina transparent ceramic is since coming out the sixties in last century, and crystalline ceramics is widely used in the discharge vessel of high-intensity gas discharge lamp.At the beginning of the nineties in last century, people have proposed a kind of new discharge vessel structure, and the thin structure in promptly middle thick (formation discharge space) two ends prevents that electrode from being corroded by high-temperature gas.One need carry out the surface finish processing to the biscuit of this crystalline ceramics pipe before sintering, and reduces the processing capacity in later stage.Because the biscuit of ceramics intensity of this structure is very low, the chucking power that can bear is very little; Therefore, the thin tube part branch at two ends ruptures easily when the rotation polishing.Therefore, need a kind of suitable anchor clamps, make it can bear clamping and rotate the destruction of being brought.
The utility model content
The purpose of this utility model be to provide a kind of when guaranteeing that the discharge vessel biscuit can be realized polishing high speed rotating and the anchor clamps that are not destroyed.
The technical solution adopted in the utility model is: a kind of anchor clamps of ceramic discharge shell biscuit, it is characterized in that, and comprise core bar (1), fixed core pole socket (2), slide core pole socket (3) and a rotary pawl (6) that is with two resilient rubbber cushions (4,5); Slide core pole socket (3) comprises slide head (31) and the thimble seat (33) that connects by bearing (32), thimble seat (33) and thimble (7) assembling; One end of core bar (1) and fixed core pole socket (2) interference fit or one-body molded, the other end and slide head (31) matched in clearance; An end that is not connected core bar (1) on rotary pawl (6) and the fixed core pole socket (2) connects.
Further, the internal diameter of resilient rubbber cushion (4,5) is slightly less than the diameter of core bar (1).
The utility model in use, the biscuit (8) of the ceramic discharge shell of want clamping is enclosed within the middle of the core bar (1), two rubber blankets (4,5) that are enclosed within on the core bar withstand the two ends of biscuit (8) respectively by the elastic force of thimble, utilize rubber to produce bigger frictional force and drive biscuit (8) and rotate with core bar (1).
The beneficial effects of the utility model are: these anchor clamps can be installed on the miniature instrument lathe, the clamping biscuit rotates together, avoided the breakage of clamping itself, made biscuit can bear the centrifugal force that high speed rotating produces, thereby avoid because of breaking that vibrations cause to the biscuit of ceramic discharge shell; Make biscuit of ceramics in when polishing high speed rotating and not being destroyed.
Description of drawings
Fig. 1 is the profilograph of the utility model one specific embodiment.
Among the figure: 1. core bar, 2. fixed core pole socket, 3. slide core pole socket, 4. rubber blanket, 5. rubber blanket, 6. rotary pawl, 7. thimble, the 8. biscuit of ceramic discharge shell, 31. slide heads, 32. bearings, 33. thimble seats.
The specific embodiment
Further set forth the utility model below in conjunction with specific embodiment, should be understood that these embodiment only be used to the utility model is described and be not used in the restriction protection domain of the present utility model.
As shown in Figure 1, the anchor clamps of a kind of ceramic discharge shell biscuit of the present utility model comprise core bar 1, fixed core pole socket 2, slide core pole socket 3 and a rotary pawl 6 that is with two resilient rubbber cushions 4,5.Slide core pole socket 3 comprises slide head 31 and the thimble seat 33 that connects by bearing 32, and the effect of bearing 32 is isolated rotations; Thimble seat 33 and thimble 7 assemblings.One end of core bar 1 and fixed core pole socket 2 interference fit or one-body molded play fixing and gearing, the other end of core bar 1 and slide head 31 matched in clearance.An end that is not connected core bar 1 on rotary pawl 6 and the fixed core pole socket 2 connects.
During use, the biscuit 8 of the ceramic discharge shell of clamping is enclosed between rubber blanket 4 and the rubber blanket 5, utilizes rubber to produce bigger frictional force and drive biscuit 8 and rotate with core bar 1.When changing workpiece, at first remove thimble 7, take off slide core pole socket 3 and rubber blanket 5 successively, change biscuit 8 then, then load onto rubber blanket 5 and slide core pole socket 3 successively, at last thimble 7 is withstood thimble seat 33.
Usually the diameter of core bar 1 make core bar can pass biscuit, but the endoporus at biscuit 8 two ends and the gap between the core bar 1 is no more than 0.2mm according to the two ends internal orifice dimension decision of the biscuit 8 of want clamping.
Further, the internal diameter of rubber blanket 4,5 is more smaller than core bar 1 diameter, but can slide on core bar under the active force of thimble.
Claims (2)
1. the anchor clamps of a ceramic discharge shell biscuit is characterized in that, comprise core bar (1), fixed core pole socket (2), slide core pole socket (3) and a rotary pawl (6) that is with two resilient rubbber cushions (4,5); Slide core pole socket (3) comprises slide head (31) and the thimble seat (33) that connects by bearing (32), thimble seat (33) and thimble (7) assembling; One end of core bar (1) and fixed core pole socket (2) interference fit or one-body molded, the other end and slide head (31) matched in clearance; An end that is not connected core bar (1) on rotary pawl (6) and the fixed core pole socket (2) connects.
2. the anchor clamps of ceramic discharge shell biscuit as claimed in claim 1 is characterized in that, the internal diameter of resilient rubbber cushion (4,5) is slightly less than the diameter of core bar (1).
