Abstract
The utility model discloses a chuck master capable of fast opening/closing, which can adjust a handle axis and a chuck axis to a reasonable position conveniently according to an operator's requirement. The utility model is composed of a handle, an upper master body, a spring, a gear rack, a triangle head key, an elliptic [al] cam, a set screw, a circlip, and a lower master body. When the gear rack is free from exogenic action, the upper master body and the lower master body are connected together by a spline; when the gear rack is under the exogenic action, the triangle head key in the upper master body is disengaged from a spline groove by the action of a transmission mechanism to disengage the upper master body from the lower master body, and the position of the handle axis on the upper master body can be adjusted when the lower master is in an immovable state.
Description
The utility model relates to a kind of improved chuck handle, particularly a kind of chuck handle that can quickly opening and closing.
Existing chuck handle is made up of wrench body and handle, and wrench body is a monoblock type, and the whole of use are this structures now.The square tenon of chuck wrench is inserted in the square hole of bevel pinion on the chuck, claw is moved, finish clamping work by the rotating chuck spanner.Because wrench body is to fixedly connected with handle, so the position between square tenon and the handle axis is constant.Again because the square hole position on the chuck bevel pinion is a size with diameter of work changes, therefore, just there are an angle in handle axis and chuck axis during each clamping workpiece on horizontal plane, are baseline with the chuck axis, just clockwise turn to.Because operator's position is constant, have only when this angle equals 0-25 °, just to be best firmly state.If surpass this scope, will make the operator be difficult to effective clamping work pieces.If undue force also may damage operator's health.Though the operator can be by selecting some angle with rational scopes that reaches of 3 bevel pinions on the chuck, this must cause muscle power and waste of time, and can make the operator produce boredom.
The purpose of this utility model is to provide a kind of chuck handle that can quickly opening and closing, and it can adjust to rational position with handle axis and chuck axis according to operator's needs.
It is as follows that the utility model is implemented main case: it is owing to handle, upper ejector lever body, spring, tooth bar, triangular joint bond, elliptic cam, dog screw, jump ring, lower ejector lever body are formed.Handle is set in the circular hole at upper ejector lever body top, outwards placing spring and tooth bar in the obstructed circular hole at upper ejector lever body middle part successively from the lining, the gear at the elliptic cam top in tooth bar and the upper ejector lever body bottom step hole is meshed, elliptic cam is stuck in the circular hole of upper ejector lever body by jump ring, can only rotate and can not move.In the step hole outside one symmetrical rectangle groove is arranged, place a pair of triangular joint bond in the groove, its profile of tooth is the involute that pressure angle equals 45 °.One flat blind hole is arranged in the lower ejector lever, and top, hole is inserted with 60 ° of-90 ° of serrations, and the lower side in the hole has a screw, is rotary with a socket cap dog screw in the hole.
The utility model advantage is: owing to only need disengagement that the control tooth bar just can finish chuck handle and engage, so use is convenient especially; Reliable in action, compact conformation, cost is lower.

This device is made up of upper ejector lever body (2) and lower ejector lever body (9) two large divisions.One cylindrical hole is radially arranged at last wrench body (2) top, and handle (1) is by in the interference load hole.Be placed with spring (4) and tooth bar (3) respectively in the radially obstructed circular hole at upper ejector lever body (2) middle part, tooth bar (3) is made by a cylinder, and right-hand member is fixed with a plastic button.Upper ejector lever body (2) bottom is a stage, one cylindrical step hole is arranged in it, an elliptic cam (6) is housed in the hole, the difference of its major axis and minor axis is greater than 2 times spline tooth depth, elliptic cam (6) top is-6-9 tooth cylindric straight-tooth gear to be meshed with tooth bar (3).Elliptic cam (6) is spacing by jump ring (8), and it can not be moved vertically.There is a symmetrical rectangle groove in the step hole outside, places a pair of triangular joint bond (5) in the groove, and the length of singly-bound from middle line to a corresponding end equals half of difference that footpath the spline deducts elliptic cam (6) long axis length.Lower ejector lever body (9) inside is a flat blind hole, and the first half in hole is inserted with 60 ° of-90 ° of serrations of 30 or 32 or 34 teeth.The bottom outside in hole has a location screw (7), and the socket cap on the dog screw (7) snaps in the locating slot of upper ejector lever body (2) bottom, upper ejector lever body (2) and lower ejector lever body (9) can only be rotated mutually, and can not move mutually.Lower ejector lever body (9) lower end is a square tenon.
Under shown position, tooth bar (3) is subjected to spring (4) effect to be in extreme position, the major axis of elliptic cam this moment (6) overlaps with triangular joint bond (5) symmetrical center line, the trigonocephalia part of triangular joint bond (5) is fitted tightly with 60 ° of-90 ° of bougainvillea keyways, simultaneously owing to oval stopping of protruding (6) makes triangular joint bond (5) not withdraw from from keyway, upper ejector lever body (2) just one is surpassing by keyed engagement with lower ejector lever body (9), and turning handle (1) just can drive lower ejector lever body (9) and rotate synchronously with upper ejector lever body (2).
Press the button of carry-over bar (3) right-hand member, after rotating 90 °, gear driven elliptic cam (6) by elliptic cam (6) upper end stopped stop motion, at this moment the minor axis of elliptic cam (6) overlaps with the symmetrical center line of triangular joint bond (5), because gapped existence, and the gap is greater than 2 times spline tooth depth, so triangular joint bond (5) just withdraws from from 60 ° of-90 ° of serrations fully, upper ejector lever body (2) is just thrown off voluntarily with lower ejector lever body (9), this moment, turning handle (1) just can make upper ejector lever body (2) rotate again, and lower ejector lever body (9) is motionless, also just can adjust the angle between handle axis and the chuck axis as required.
Claims (3)
1, chuck handle that can quickly opening and closing is characterized in that: be made up of upper ejector lever body (2) and lower ejector lever body (9) two large divisions.
2, the chuck handle of stipulating by claim 1, it is characterized in that placing spring (4) and tooth bar (3) respectively in the obstructed circular hole at upper ejector lever body (2) middle part, the gear of elliptic cam (6) upper end in tooth bar (3) and upper ejector lever body (2) the bottom step hole is meshed, elliptic cam (6) is stuck in the upper ejector lever body by jump ring (8), in the step hole outside one symmetrical rectangle groove is arranged, place a pair of triangular joint bond in the groove, its profile of tooth is the involute that pressure angle equals 45 °.
3, by the chuck handle of claim 1 regulation, it is characterized in that a flat blind hole is arranged in the lower ejector lever body (9), it is 60 °-90 ° serration that top, hole is inserted with profile of tooth, and the lower side in the hole has a screw, is rotary with certain position screw in the hole.
