Abstract
The utility model provides a clamp for grinding a hole on a shaft. The clamp comprises a jacket seat and a spring jacket, wherein a central through hole is positioned in the jacket seat, a conical opening is positioned at one end of the central through hole, the spring jacket comprises a tail section and a throat section, the outer wall of the end of the throat section is in a conical shape, the spring jacket is sleeved in the central through hole of the jacket seat and can axially move in the central through hole, and the outer wall of the end of the throat section of the spring jacket is matched with the conical opening of the central through hole. The outer wall of the end of the throat section of the spring jacket is matched with the conical opening of the central through hole, so that when a corrected part is inserted into the spring jacket, the spring jacket is in a clamp state to clamp a standard part. Thus, a three-claw chunk is substituted, work efficiency for replacing parts is improved, and product accuracy and product quality are also improved.
Description
Technical field
The utility model relates to fixture, relates in particular to a kind of fixture for axle spare grinding out.
Background technology
The endoporus of machining shaft spare all will be used the three-jaw fluid-pressure chuck basically at present, directly directly begin to grind endoporus with scroll chuck clamp shaft series products benchmark place, because axis products itself is long, bare terminal end is longly not outstanding when the length that adds scroll chuck just makes grinding out, thereby can not guarantee the axiality of the endoporus of processing and axle cylindrical, cause the precision of interior hole dimension and quality all not to reach requirement.A machine tool needs often to change dissimilar product, not only can not repair the assurance clamp precision when repairing scroll chuck, has also reduced production efficiency.
The utility model content
The technical problem that the utility model solves is: a kind of fixture for axle spare grinding out is provided, need not repaiies scroll chuck in the replacing product on lathe, can improve production efficiency.
The technical solution of the utility model is: a kind of fixture for axle spare grinding out, comprise chuck seat and spring chuck, described chuck seat is provided with central hole, one end of this central hole has conical uncovered, described spring chuck comprises rear and reducing section, it is conical that the end outer wall of described reducing section is, and described spring chuck can axially movablely be set in the central hole of described chuck seat, and conical uncovered the matching of the end outer wall of the reducing section of spring chuck and described central hole.
The rear of spring chuck extends the central hole of described chuck seat, and the end face of described rear is fixed with pull bar.
Pull bar is fixed on the end face of described rear by a terminal pad.
The bottom of spring chuck is fixed with top.
Top top body, dead head and the top conical points body of comprising.
The outer surface of spring chuck is provided with and extends axially groove, and described chuck seat is provided with radial screw, and described screw screws in described groove and and described groove gapped space.
The beneficial effects of the utility model are: a kind of fixture for axle spare grinding out, comprise chuck seat and spring chuck, the chuck seat is provided with central hole, described spring chuck comprises rear and reducing section, the spring chuck can axially movablely be set in the central hole of described chuck seat, because an end of this central hole has conical uncovered, it is conical that the end outer wall of described reducing section is, and the end outer wall of the reducing section of spring chuck and conical uncovered the matching of described central hole, thereby be clamped condition at the process medi-spring chuck that uses.
The rear of spring chuck extends the central hole of described chuck seat, the end face of described rear is fixed with pull bar, pull bar is fixed on the end face of described rear by a terminal pad, the bottom of spring chuck is fixed with top, top top body, dead head and the top conical points body of comprising.The described top rear that is fixed on described spring chuck.
Extend axially groove because the outer surface of spring chuck is provided with, described chuck seat is provided with radial screw, described screw screw in described groove and and described groove gapped space, thereby make chuck seat and spring chuck can only move left and right and can not rotate.
When using the utility model, spring chuck and toply backward move together, due to and conical uncovered the matching of the end outer wall of the reducing section of spring chuck and described central hole, when the check and correction part inserts the spring chuck, the spring chuck is in clamped condition, clamp the check and correction part, then the top centre bore the inside that withstands on the check and correction part, after the check and correction part is proofreaied and correct fixture, just can process product, thereby substituted scroll chuck, not only improved the operating efficiency of changing part when changing product, and in precision with also be improved qualitatively.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top structural representation in the utility model;
Fig. 3 is use state diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to Fig. 1, Fig. 2, a kind of fixture for axle spare grinding out, comprise chuck seat 1 and spring chuck 2, chuck seat 1 is provided with central hole, described spring chuck 2 comprises rear and reducing section, spring chuck 2 can axially movablely be set in the central hole of described chuck seat 1, because an end of this central hole has conical uncovered, it is conical that the end outer wall of described reducing section is, and the end outer wall of the reducing section of spring chuck 2 and conical uncovered the matching of described central hole, thereby be clamped condition at the process medi-spring chuck 2 that uses.
The rear of spring chuck 2 extends the central hole of described chuck seat 1, the end face of described rear is fixed with pull bar 3, pull bar 3 is fixed on the end face of described rear by a terminal pad 4, the bottom of spring chuck 2 is fixed with top 5, top 5 and comprises top body 5b, dead head 5a and top conical points body 5c.Described top 5 are fixed on the rear of described spring chuck 2.
Extend axially groove because the outer surface of spring chuck 2 is provided with, described chuck seat 1 is provided with radial screw 7, described screw 7 screw in described grooves and and described groove gapped space, thereby make chuck seat 1 and spring chuck 2 can only move left and right and can not rotate.
to use like this referring to Fig. 3 the utility model, first ring flange 8 directly is connected on the main shaft of lathe, the debugging lathe, then pack into and proofread part 9, due to and conical uncovered the matching of the end outer wall of the reducing section of spring chuck 2 and described central hole, when top 5 withstand on the centre bore of check and correction part 9, top 5 and spring chuck 2 move backward, spring chuck 2 will be proofreaded part 9 and clamp, then begin fixture is proofreaded, check and correction just can be processed product later, when changing product, only need replacing pull bar 3 and spring chuck 2 just can process, thereby not at the needs scroll chuck.
