Abstract
The utility model belongs to the technical field of mechanical tools, and particularly relates to a bulging fixture, which comprises a support plate, a connecting rod, a connecting plate, an expansion block, an ejector plate, a bearing and an ejector rod. Both the support plate and the connecting plate are round plate parts and connected together through the connecting rod, the connecting plate and the expansion block are connected together through screws, an inner conical face is arranged on the inner profile of the expansion block, an outer conical face is arranged on the outer periphery of the ejector plate, the bearing is mounted at the center of the ejector plate through a retainer ring, and the bearing and the ejector rod are connected together through a pressure cap and screws. Inner holes of thin-wall parts are supported under expansion of the expansion block, so that deformation of parts extruded by tools during external machining can be effectively avoided.
Description
Technical field
The utility model belongs to the machine tool technical field, particularly relates to a kind of bulging anchor clamps.
Background technology
In mechanical processing industry; Often run into the processing situation of thin-walled cover parts; Simple cylindrical clamping has caused the crimp of part, and the Cutting Force during cylindrical turning also can make part deformation, therefore designs a kind ofly can prevent effectively that the anchor clamps of thin-walled cover parts clamping deformation are necessary.
Summary of the invention
The objective of the invention is:
The purpose of the utility model provides a kind of bulging anchor clamps, and these anchor clamps can prevent effectively to prevent thin-walled cover parts clamping deformation.
Technical scheme of the present invention is:
This bulging anchor clamps comprise gripper shoe, connecting rod, connecting plate, the piece that rises, top board, bearing, push rod; Gripper shoe and connecting plate are the circular plate type part, link together through connecting rod, and connecting plate links together through screw with the piece that rises; The interior type of the piece that rises is shaped on inner conical surface; The top board cylindrical is shaped on male cone (strobilus masculinus), and the top board center is equipped with bearing through back-up ring, and bearing and push rod link together through gland and screw.
The invention has the beneficial effects as follows:
The utility model is through the tensioner effect of the piece that rises, and the endoporus of thin-walled parts is played the effect of support, can prevent effectively that cylindrical from adding the cutter distortion that extruding is taken place to part in man-hour.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention, and wherein, 1 is part, and 2 is gripper shoe, and 3 is hole in piece part; 4 for connecting club head, and 5 is connecting rod, and 6 is three-jaw chuck, and 7 for connecting club head, and 8 is screw; 9,10 is inner conical surface, and 11 is the top board male cone (strobilus masculinus), and 12,13 is top board; 14 is back-up ring, and 15 is bearing, and 16 is gland, and 17 is push rod, and 18 is screw.
Accompanying drawing 2 is a partial sectional view of the present invention, and wherein 19 are the piece that rises, and 20 are the piece that rises, and 21 are the piece that rises.
Accompanying drawing 3 is top board of the present invention and push rod syndeton sketch map.
The specific embodiment
Include these anchor clamps gripper shoe 2, connecting rod 5, connecting plate 12, the piece 19 that rises rise piece 20 rise piece 21, top board 13, bearing 15, push rod 17.Gripper shoe 2 is the circular plate type part with connecting plate 12; Bar head 4 and 7 through connecting rod 5 links together; Connecting plate 12 and the piece 19 that rises piece 20 piece 21 that rises that rises links together through screw 8, and the piece 19 that the rises piece 20 that rises rises that types are shaped on inner conical surface 10 in the piece 21, and top board 13 cylindricals are shaped on male cone (strobilus masculinus) 11; Top board 13 centers are equipped with bearing 15 through back-up ring 14, and bearing 15 links together through gland 16 and screw 18 with push rod 17.
The utility model in use, at first with part 1 clamping on three-jaw chuck 6, in part 1 hole 3 of jaw 6 one ends gripper shoe 2 is installed, prevent crimp.Push rod 17 with the pressure of outside through bearing 15 and top board 13 be delivered to the piece 19 that rises, on the piece 20 that rises, the piece 21 that rises, the piece 19 that rises, the piece 20 that rises, the part 1 that risen by piece 21 stress deformation tensioners have prevented the distortion of clamping.
