Abstract
A clamp for processing a rotor comprises a cylinder, a clamp holder and an expansion sleeve, wherein the clamp holder is connected with the cylinder body through a connection block; a support rod is arranged on the front end of the clamp holder in a forward extension manner; a through -hole is formed on the axial centers of the clamp holder and the support rod, which has a conical outer wall; the expansion sleeve is sheathed on the outer wall of the expansion rod; the piston rod of the cylinder penetrates the through-hole and the front end wall of the expansion sleeve; two nuts are arranged on the front end of the piston rod to sandwich the front end wall of the expansion sleeve. A rotor to be processed is sheathed on the support rod and the expansion sleeve. When retracted, the piston of the cylinder drives the expansion sleeve to move toward the support rod, so that the expansion sleeve can be expanded by the conical surface of the support rod to support the rotor tightly, thereby achieving workpiece clamping. When protruded, the piston of the cylinder drives the expansion sleeve to withdraw from the support rod, so that the expansion sleeve is recovered to unclamp the rotor. The clamp has convenient operation, and can eliminate the gap between the outer side surface of the clamp and the rotor and enhance the rigidity of the clamp, thereby improving the processing accuracy.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to anchor clamps, particularly a kind of anchor clamps that are used for processing rotor.
Background technology:
In the prior art, locate in two ends of rotor by the Double Tops point when rotor is carried out the axial groove grinding, clamp by scroll chuck again,, had the problem of location because scroll chuck and Double Tops point all carry out axial location to rotor; Simultaneously, rotor is fixed on the anchor clamps by nut, and clamping and dismounting are all inconvenient, and artificial factor is bigger during clamping workpiece, and efficient is not high, and anchor clamps mandrel span is big, rigidity is bad, has influenced the machining accuracy of rotor.
Summary of the invention:
The purpose of this utility model is to provide a kind of anchor clamps that are used for processing rotor, and there was the location in the anchor clamps that the described this anchor clamps that are used for processing rotor will solve the prior art processing rotor, uses inconvenience and the not high technical problem of machining accuracy.
This anchor clamps of processing rotor that are used for of the present utility model are by cylinder, clamping seat and expansion set constitute, wherein, described clamping seat is connected with the cylinder body of described cylinder by a contiguous block, the front end of clamping seat extends forward and is provided with a support bar, the axle center of clamping seat and support bar is provided with a through hole, the outer wall of described support bar is tapered, described expansion set is set on the outer wall of support bar, the piston rod of cylinder passes the front bulkhead of described through hole and expansion set, the front end of piston rod is provided with screw thread, the front end of piston rod has one first nut and one second nut, and the front bulkhead of expansion set is between described first nut and second nut.
Further, the inwall of described expansion set is provided with the conical surface, and the two ends of expansion set are evenly equipped with three grooves separately, and the length direction of any described groove all is parallel to the axial of expansion set.
Further, the maximum outside diameter of described clamping seat is greater than the maximum gauge of support bar.
Operation principle of the present utility model is: rotor to be processed is set on support bar and the expansion set, and in abutting connection with the front end face of clamping seat, during the cylinder piston rod withdrawal, driving expansion set moves to support bar, the conical surface of support bar makes the expansion set distending, and the swelling rotor is finished a clamping of workpiece.After workpiece machined, cylinder piston rod stretched out, and drove expansion set and withdrawed from support bar, and expansion set recovers, and unclamps rotor, and workpiece just can take off.
The utility model and prior art compare, and its effect is actively with tangible.The utility model utilizes the air cylinder driven expansion set, utilizes expansion set that rotor is clamped and loosen, and is easy to operate, eliminated anchor clamps lateral surface and gap between rotor, strengthened the rigidity of anchor clamps, thereby improved machining accuracy.
Description of drawings:
Fig. 1 is the structural representation that is used for the anchor clamps of processing rotor of the present utility model.
Fig. 2 is the structural representation that is used for the anchor clamps expansion set of processing rotor of the present utility model.
The specific embodiment:
Embodiment 1:
As Fig. 1, shown in Figure 2, the anchor clamps that are used for processing rotor of the present utility model, by cylinder 1, clamping seat 2 and expansion set 3 constitute, wherein, described clamping seat 2 is connected with the cylinder body of described cylinder 1 by a contiguous block 4, the front end of clamping seat 2 extends forward and is provided with a support bar 21, the axle center of clamping seat 2 and support bar 21 is provided with a through hole, the outer wall of described support bar 21 is tapered, described expansion set 3 is set on the outer wall of support bar 21, the piston rod 6 of cylinder 1 passes the front bulkhead of described through hole and expansion set 3, the front end of piston rod 6 is provided with screw thread, the front end of piston rod 6 is combined with one first nut 7 and one second nut 8, and the front bulkhead of expansion set 3 is between described first nut 7 and second nut 8.
Further, the inwall of described expansion set 3 is provided with the conical surface, and the two ends of expansion set 3 are evenly equipped with three grooves 10 separately, and the length direction of any described groove 10 all is parallel to the axial of expansion set 3.
Further, the maximum outside diameter of described clamping seat 2 is greater than the maximum gauge of support bar 21.Clamping seat 2 is fixing with contiguous block 4 by bolt 5.
The course of work of the present utility model is: rotor 9 to be processed is set on support bar 21 and the expansion set 3, and in abutting connection with the front end face of clamping seat 2, during 6 withdrawals of cylinder 1 piston rod, driving expansion set 3 moves to support bar 21, the conical surface of support bar 21 makes expansion set 3 distendings, swelling rotor 9 is finished a clamping of workpiece.After workpiece machined, cylinder 1 piston rod 6 stretched out, and drove expansion set 3 and withdrawed from support bar 21, and expansion set 3 recovers, and unclamps rotor 9, and workpiece just can take off.
