The utility model discloses a kind of vertical car centralizer of improvement, comprise power clamp head main body (1), center disc spring (2), hold-down head (3), telescopic claw (4), little chuck pulls pawl (5), little chuck pull plate (6), telescopic head (7), lathe drawhead (8), power clamp head main body (1) is bolted on jig basis, telescopic head (7) is connected with lathe oil cylinder pull bar, telescopic claw (4) and little chuck pull pawl (5) to be connected, little chuck pulls pawl (5) to be connected with little chuck pull plate (6), little chuck pull plate (6) is connected with fixture radial sledge, hold-down head (3) is connected with telescopic head (7), center disc spring (2) is installed in telescopic head.The utility model center location structure is simple, saves the large connectors of former fixture, can reach the object of stabilizing clip precision, and the simplification of fixture spare part, can accomplish that fixture overhauls less peopleization operation, easily recover.
Description
Technical field
The utility model relates to positioner, is mainly used in working clamp for wheel location.
Background technology
At present, domestic general vertical Che Yixu automatic wheel clamp for machining is linked formed by float plate, vertical car slide, spring, linear bearing.In jig main body, floating disc moves up and down, and pulls fixture location-plate upper saddle to realize radially sliding location.There is the shortcomings such as maintenance period is short, spare part loss large, fixture parts replacement confirms Precision Time length, fixture maintenance duration, the time between overhauls(TBO) is too short, the difficult recovery of the abnormal collision of lathe in this fixture, and clamp precision generation deviation, the inclined car waste product of easy generation, balance ultra-poor products, ultra-poor products etc. of beating, seriously delay machined yield rate.
Summary of the invention
In order to solve the problem, the utility model provides a kind of vertical car centralizer of improvement.
The vertical car centralizer improved, comprise power clamp head main body, center disc spring, hold-down head, telescopic claw, little chuck pulls pawl, little chuck pull plate, telescopic head, lathe drawhead.Power clamp head main body is bolted on jig basis, telescopic head is connected with lathe oil cylinder pull bar, telescopic claw pulls pawl to be connected with little chuck, little chuck pulls pawl to be connected with little chuck pull plate, little chuck pull plate is connected with fixture radial sledge, hold-down head is connected with telescopic head, and center disc spring is installed in telescopic head.During clamping and release, oil cylinder pull bar upwards, action downwards, promote hold-down head, telescopic head move up and down, drive telescopic claw 4 to connect little chuck and pull pawl, little chuck pull plate stretching motion.
The utility model is by " floating disc in jig main body moves up and down and pulls slide " in prior art, change to center power collet movement, center location structure is simple, save the large connectors of former fixture, the object of stabilizing clip precision can be reached, and the simplification of fixture spare part, can accomplish that fixture overhauls less peopleization operation, easily recover.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-power clamp head main body, 2-center disc spring, 3-hold-down head, 7-telescopic head, 4-telescopic claw, the little chuck of 5-pulls pawl, the little chuck pull plate of 6-, 8-lathe drawhead.
Detailed description of the invention
The vertical car centralizer improved, comprise power clamp head main body 1, center disc spring 2, hold-down head 3, telescopic claw 4, little chuck pulls pawl 5, little chuck pull plate 6, telescopic head 7, lathe drawhead 8.Power clamp head main body 1 is bolted on jig basis, telescopic head 7 is connected with lathe oil cylinder pull bar, telescopic claw 4 and little chuck pull pawl 5 to be connected, little chuck pulls pawl 5 to be connected with little chuck pull plate 6, little chuck pull plate 6 is connected with fixture radial sledge, hold-down head 3 is connected with telescopic head 7, and center disc spring 2 is installed in telescopic head.During clamping and release, oil cylinder pull bar upwards, action downwards, promote hold-down head 3, telescopic head 7 move up and down, drive telescopic claw 4 to connect little chuck and pull pawl 5, little chuck pull plate 6 stretching motion.
The utility model arranges power chuck, connects slide by pulling claw, chuck stretch realize slide slip tension location.
When lathe unclamps, first clamp upwards action by telescopic head 7, by the structure that hold-down head 3 is connected with telescopic head 7, upwards jack-up, center disc spring 2 compressed, telescopic claw 4, in the upwards action of hold-down head 3 inclined-plane, guides little chuck to pull pawl 5 and little chuck pull plate 6 to unclamp radially outward action.
During lathe clamping, first clamp downward action by telescopic head 7, by the structure that hold-down head 3 is connected with telescopic head 7, upwards jack-up, center disc spring 2 compressed, telescopic claw 4 is the downward action in inclined-plane in hold-down head 3, guides little chuck to pull pawl 5 and little chuck pull plate 6 to unclamp radially outward action.
Claims (1)
1. the vertical car centralizer improved, comprise power clamp head main body (1), center disc spring (2), hold-down head (3), telescopic claw (4), little chuck pulls pawl (5), little chuck pull plate (6), telescopic head (7), lathe drawhead (8), it is characterized in that: power clamp head main body (1) is bolted on jig basis, telescopic head (7) is connected with lathe oil cylinder pull bar, telescopic claw (4) and little chuck pull pawl (5) to be connected, little chuck pulls pawl (5) to be connected with little chuck pull plate (6), little chuck pull plate (6) is connected with fixture radial sledge, hold-down head (3) is connected with telescopic head (7), center disc spring (2) is installed in telescopic head.
