Abstract
The utility model relates to a processing device of a reducer, in particular to an inner bore grinding fixture special for a bore type worm of a reducer, and mainly solves the technical problems that a three-jaw chuck is used for clamping an excircle for grinding an inner bore of a worm, the coaxiality of the inner bore and the excircle cannot meet requirements of a drawing when a locating sleeve is used for locating a little end, and an elastic chuck and the like cannot be used when the worm is provided with steps. The fixture comprises a fixture body (1) and is characterized in that the excircle of the fixture body (1) is provided with a Morse taper (2), a center (3) capable of abutting the little end face of the worm is penetrated in the fixture body (1) , a V-shaped locating block (4) is arranged at one end of the fixture body (1), and a platen (6) is fixed above the V-shaped locating block through a set screw (5).
Description
Technical field
The utility model relates to a kind of process equipment of decelerator, especially relates to a kind of decelerator cellular type worm screw Special grinding internal clamp.
Background technology
At present, the gear reduction unit of being used widely, worm-gear speed reducer, be subject to volume restrictions, its speed ratio is less than normal, and its transmission direction is generally parallel input and output and can not satisfies some existing large speed ratios mini-plant that has again the vertical-transmission direction to require that slows down and install and use.Chinese patent discloses a kind of double worm gear reducing mechanism (Granted publication number: CN 201250880Y), it comprises worm type of reduction gearing, be provided with two worm type of reduction gearings, worm screw on two worm type of reduction gearings links together by the adjustable shaft coupling of axial rotation angle, realizes synchronization; Have at least one worm screw two ends all to stretch out in himself reducer shell in two worm type of reduction gearings, with a end that shaft coupling is not installed on this worm screw power shaft as this reducing gear; Output shaft on each worm type of reduction gearing is connected with respectively a pinion; Pinion simultaneously and the gear wheel engaged transmission, and with the power transmission shaft at the gear wheel place output shaft as this reducing gear; The two ends of the worm screw of two worm type of reduction gearings all stretch out in the separately housing of decelerator itself, two worm type of reduction gearings and connected pinion respectively, has respectively identical specification, the shaft coupling that employed axial rotation angle is adjustable is made of two half a couplers, some screws evenly distribute on one of them half a coupler, corresponding described screw is provided with the slotted hole of some arcs on another half a coupler, is fastenedly connected by screw between two half a couplers.At present this worm screw of processing is generally used excircle orientation, and with the direct clamping cylindrical of scroll chuck, when small end was located with positioning sleeve, because the accuracy limitations of chuck own, endoporus and outer circles did not reach drawing requirement.The other high precision elastic chuck on the market, clamping range is less, if worm screw is provided with step, then can not use collet.
The utility model content
The utility model provides a kind of decelerator cellular type worm screw Special grinding internal clamp, it mainly is to solve the existing grinding worm endoporus of prior art with the direct clamping cylindrical of scroll chuck, when small end is located with positioning sleeve, endoporus and outer circles do not reach drawing requirement, and when worm screw is provided with step, can not use the first-class technical problem of elastic clip.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Decelerator cellular type worm screw Special grinding internal clamp of the present utility model, comprise clamp body, the cylindrical of described clamp body is provided with Morse's taper, the inner cross-under of clamp body has can withstand the top of worm screw small end face, clamp body one end is provided with the V-type locating piece, and V-type locating piece top is fixed with pressing plate by holding screw.These anchor clamps cooperate with inner circle mill spindle taper hole with the cylindrical Morse's taper, install to lathe and go forward, and the school mixes up and beats first.When workpiece was installed, the top worm screw small end center hole that heads into anchor clamps utilized the effect of top tail compression spring, the step of large cylindrical one end of worm screw withstands the V-type locating piece, rotate at last pressing plate, the oval styletable of square toes is fixed with holding screw, grinds at last inner bore of worm.
As preferably, describedly toply be connected with the adjusting double-screw bolt by the first hexagon socket cap head screw, regulate double-screw bolt and be threaded in clamp body inside, regulate double-screw bolt and top between be provided with Compress Spring.Regulate double-screw bolt by turn, can be so that toply withstand worm screw.
As preferably, described V-type locating piece also is provided with straight pin by the second hexagon socket cap head screw jockey body on the V-type locating piece.Can play the positioning action of V-type locating piece on clamp body by straight pin.
Therefore, the utility model is installed simple, need not the school after being installed on the internal grinder to transfer, and directly the anchor clamps outer cone is cooperated with tapered bore of machine tool spindle; Clamping workpiece is convenient, worm screw is headed into to clamp behind the anchor clamps get final product grinding, whole installation steps simple and fast; Use these anchor clamps than the workpiece with three-jaw clamping processing, its endoporus and outer circles have significantly raising.

The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the decelerator cellular type worm screw Special grinding internal clamp that this is routine, such as Fig. 1, Fig. 2, a clamp body 1 is arranged, the cylindrical of clamp body is provided with Morse's taper 2, the inner cross-under of clamp body has can withstand top 3 of worm screw small end face, clamp body one end is provided with V-type locating piece 4, and the V-type locating piece also is provided with straight pin 11 by the second hexagon socket cap head screw 10 jockey bodies on the V-type locating piece.V-type locating piece top is fixed with pressing plate 6 by holding screw 5.Top being connected with by the first hexagon socket cap head screw 7 regulated double-screw bolt 8, regulates double-screw bolt and is threaded in clamp body inside, regulate double-screw bolt and top between be provided with Compress Spring 9.
Install to lathe and go forward, the school mixes up and beats first.When workpiece is installed, top 3 of anchor clamps are headed into worm screw 12 small end center holes, utilize the effect of top tail compression spring 9, the step of large cylindrical one end of worm screw withstands V-type locating piece 4, rotate at last pressing plate 6, the oval styletable of square toes is fixing with holding screw 5, grinds at last inner bore of worm.
