Abstract
The utility model relates to a fixture which comprises a fixture seat, wherein an elastic collet is arranged on the fixture seat; a threaded hole is arranged at the center of the fixture seat; a round hole is arranged at the center of the elastic collet, communicated with the threaded hole, and the same as the threaded hole in diameter; a conical screw rod is disposed in the round hole and the threaded hole; the small diameter end of the conical screw rod is matched with the threaded hole; the elastic collet is connected with the fixture seat through a fastening piece; and a handle is disposed at the major diameter end of the conical screw rod. When the fixture is used, a shaft sleeve to be machined is sleeved on the elastic collet first, and then the conical screw rod is screwed in the threaded hole and the major diameter end of the conical screw rod shoves the elastic collet open to achieve the purpose of clamping of the shaft sleeve to be machined. The fixture solves the problem that the end face of the shaft sleeve is pressed to be damaged due to the fact that a pneumatic pressure head of a former fixture directly presses the shaft sleeve rigidly, and greatly improves machining quality of the shaft sleeve.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly be a kind of anchor clamps that are used to process axle sleeve.
Background technology
Axle sleeve is a kind of important machine components, is used in widely on gear shaft or the bearing, and centralized positioning and the bearing that is used for fixing axle do not allowed it and be shifted because shake during running.Therefore axle sleeve is the hollow and annular body, need use anchor clamps man-hour adding.Anchor clamps in the past, shown in accompanying drawing 1, axle sleeve 1 to be processed is enclosed within on the protrusion cylinder of clamping fixture seat 2, through pneumatic pressure head 3 axle sleeve 1 is pressed on the clamping fixture seat 2 then.Such anchor clamps because being pressed on the axle sleeve to be processed 1 of pneumatic pressure head 3 direct rigidity is easy to the end face of axle sleeve to be processed 1 is weighed wounded, have influenced the quality of axle sleeve processing.
The utility model content
The utility model purpose is for the deficiency that overcomes prior art a kind of anchor clamps that improve the axle sleeve crudy to be provided.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of anchor clamps, comprise clamping fixture seat, and said clamping fixture seat is provided with collet; Said clamping fixture seat central authorities are provided with screwed hole; Said collet central authorities have circular hole; Said circular hole communicates with screwed hole, and Circularhole diameter is identical with the diameter of screwed hole; Be provided with conical screw in said circular hole and the screwed hole; The miner diameter end and the screwed hole of said conical screw are complementary.
Preferably, said collet is connected through securing member with clamping fixture seat.
Preferably, the bigger diameter end of said conical screw is provided with handle.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The anchor clamps of the utility model, because clamping fixture seat is provided with collet, clamping fixture seat central authorities are provided with screwed hole; Collet central authorities have circular hole, and circular hole communicates with screwed hole, and Circularhole diameter is identical with the diameter of screwed hole; Be provided with conical screw in circular hole and the screwed hole, the miner diameter end and the screwed hole of conical screw are complementary, during use; At first axle sleeve to be processed is enclosed within on the collet; Then conical screw is screwed in the screwed hole, the bigger diameter end of conical screw struts the purpose that clamps axle sleeve to be processed to reach with collet, has overcome being pressed on the axle sleeve the direct rigidity of pneumatic pressure head of anchor clamps in the past; The problem that causes the end face of axle sleeve to weigh wounded has improved the quality of axle sleeve processing greatly.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of the anchor clamps of prior art;
Accompanying drawing 2 is the structural representation of the anchor clamps of the utility model;
Accompanying drawing 3 is the user mode structural representation of the anchor clamps of the utility model;
Wherein: 1, axle sleeve to be processed; 2, clamping fixture seat; 3, pneumatic pressure head; 4, collet; 5, securing member; 6, screwed hole; 7, circular hole; 8, conical screw; 9, handle.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of anchor clamps of the utility model shown in accompanying drawing 2 comprise clamping fixture seat 2, and said clamping fixture seat 2 is provided with collet 4; Said collet 4 is connected through securing member 5 with clamping fixture seat 2; Said clamping fixture seat 2 central authorities are provided with screwed hole 6; Said collet 4 central authorities have circular hole 7; Said circular hole 7 communicates with screwed hole 6, and circular hole 7 diameters are identical with the diameter of screwed hole 6; Be provided with conical screw 8 in said circular hole 7 and the screwed hole 6; The miner diameter end of said conical screw 8 and screwed hole 6 are complementary; The bigger diameter end of said conical screw 8 is provided with handle 9.
Like the described a kind of anchor clamps of accompanying drawing 3 described the utility model, during use, at first axle sleeve to be processed 1 is enclosed within on the collet 4; Hold handle 9 then, with the taper spiral shell, 8 screw in the screwed hole 6; The bigger diameter end of conical screw 8 struts collet 4 purpose that clamps axle sleeve 1 to be processed to reach; Overcome anchor clamps in the past with being pressed on the axle sleeve to be processed 1 of pneumatic pressure head 3 direct rigidity, the problem that causes the end face of axle sleeve to be processed 1 to weigh wounded has improved the quality of axle sleeve processing greatly.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
