Abstract
The utility model relates to a mandrel processing fixture for rotating gear of shaft with a large center hole, which belongs to the technic field of the mechanical invention. The utility model comprises a mandrel and a lock component. The lock component is sleeved on the tail of the mandrel. In the middle of the mandrel is provided with a fixed part and a taper hole is provided at the front end of the mandrel. The processing fixture is used in processing shafts with the large center hole. When processing the solid shaft, a top center hole is opened on the center of the shaft and the processed substance is fixed by the center of the top center shaft of the lathe. The utility model has the advantages of simply structure, easy assembly and high processing precision and so on.
Description
Technical field
The utility model relates to a kind of big centre hole axis gear hobbing mandrel processing tool, and especially a kind of machining frock of big centre hole axis belongs to the technical field of machine-building.
Technical background
Some solid shaftings add on lathe and in the end in week center hole are set usually man-hour, by the processed axle of top pinning, make processed axle can keep alignment preferably man-hour adding, but when processed axle has big centre bore, original stationary center lost efficacy to centre bore, shortcomings such as it is difficult to cause processed axle to be fixed in the process of processing, and the processing precise degree is difficult to assurance, and alignment is bad.The patent No. is a kind of anchor clamps with machined into workpiece centre hole of CN96224842.8, it is by hinged with three joints, inner fastening fixedly semicircular cylinder and the movable semicircular cylinder of folder workpiece clamp, and with the fixing chuck and two semicircular cylinders are fastened as one and the fastener composition of clamping work pieces of the affixed annular of fixing semicircular cylinder.It also has a thrust adjusting device of being made up of screw rod, fixed block, the movable regulating block of boss shape and retainer nut.Use these anchor clamps processing work centre bore, the work efficiency height, the precision height, and can process the workpiece of various different profiles and size.Though said method work efficiency height, high its complex structure of precision will be reequiped described fixture when inconvenience and use are installed.
Summary of the invention
It is a kind of simple in structure, easy for installation that the utility model purpose is to provide, and adds the high frock of the good machining accuracy of axiality in man-hour, solved the problems referred to above that prior art exists.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs:
A kind of big centre hole axis gear hobbing mandrel processing tool is characterized in that comprising mandrel and locking member, and described locking member is enclosed within the two ends of mandrel, and described mandrel middle part is provided with fixed part, and the front end of mandrel is provided with bellmouth.This processing tool is the axle clamp for machining that is used to have big centre bore.Offer heart hole, top during real mandrel in the center of axle in processing, surely living object to be processed by the tail spindle center on the lathe gets final product, it is then difficult fixing when object to be processed has centre bore, the utility model adopts a frock to come transition to fix, be about to workpiece to be machined and be fixed on and make the coaxial same core of workpiece to be machined and fixing tool on the frock, and connection side's rule of frock and lathe employing routine techniques scheme.Described fixed part can be that a taper taper seat in the mandrel setting also can be that some the distribution symmetrically has the rib of tapering, it can also be the taper sheath that is provided with internal thread, it also can be simple nut, described locking member can be that a nut also can be the combination of nut and coning sleeve, described coning sleeve is smooth to be sleeved on the mandrel, and the rear side that nut is arranged on coning sleeve makes coning sleeve with workpiece to be machined lock jail by nut in the rotation of mandrel.
As preferably, described locking member is a locking nut, and described mandrel end has the screw thread that cooperates with nut.Locking member is a locking nut, and the threaded portion on locking nut and the mandrel cooperates, and nut is directly pushed processed parts forward in nut check, by the back thrust that the tight lock part with the mandrel front end produces processed parts is fixed.
As preferably, a coning sleeve is arranged before the described locking nut, described coning sleeve is enclosed within on the mandrel.After being provided with coning sleeve, the front end of coning sleeve can insert in the centre bore of processed parts, and the suffered clamping force of processed parts that this hook is made a show of power radially evenly distributes, and the concentricity of processed parts and mandrel is higher.
As preferably, described fixed part is a circular cone tapering face.Directly the middle part with mandrel is made into the tapering face, and the littler and processed parts of longer cone angle that can do of tapering face cooperate better like this.
As preferably, described fixed part is a coning sleeve, and described coning sleeve is provided with internal thread, and the corresponding site of described mandrel is provided with the outer rib-loop that cooperates with coning sleeve.The inside of fixed part is provided with the screw thread that cooperates with the mandrel body, and the outside is the tapering face.
As preferably, described locking member is a locking nut, and described mandrel end has the screw thread that cooperates with nut, and described locking nut front end has coning sleeve, and described fixed part is the tapering face on the mandrel at middle part, and described coning sleeve is smooth to be socketed on the mandrel.
Therefore, the utlity model has the structure assembling simply, the axiality height adds work efficiency height in man-hour, and precision is also than characteristics such as height.
Description of drawings
Accompanying drawing 1 is the structural representations of the processed parts of the utility model when being installed on the frock.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings 1, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, a kind of processing tool of big centre hole axis, it is made of mandrel 1 and locking nut 2, the middle part of mandrel 1 is a fixed part 4, and it is the part of taper seat, and its cone angle is 60 degree, on mandrel and locking nut 2 corresponding positions screw thread that matches with mandrel 1 is arranged, the locking nut front end has a coning sleeve 3, coning sleeve 3 and mandrel 1 smooth socket, and the center at the two ends of mandrel 1 all is provided with heart hole, top 5.Processed parts 6 are enclosed within put coning sleeve 3 on the mandrel 1 then, locking nut pushes away before with coning sleeve, thereby processed parts 6 are stuck between fixed part 4 and the coning sleeve 3.Be provided with heart hole, top 5 in the rear and front end of mandrel 1, the apical axis on the lathe locks frock and processes processed parts 6.
