Abstract
The utility model relates to a jig, particularly to a jig used for processing a Root's blower rotor. The two ends of a mandrel are connected with bearing seats, one end of the mandrel extends out of the bearing seat and is fixedly provided with a gear, the gear is engaged with the rack installed on the body of a planning machine, and a workpiece to be processed is installed on the mandrel between the two bearing seats. The jig is characterized in that the jig can realize the processing of an involute impeller of the Root's blower rotor on the planning machine. During processing, the impeller, as a workpiece to be processed, is fixed on a workbench of the planning machine through the bearing seats and the mandrel; and when the workbench carries out horizontal movement, the engagement of the gear installed on the mandrel with the rack fixedly installed on the body of the planning machine drives the impeller to rotate, in the way, the straight-line motion of a planer tool and the rotation of the workpiece form compound movement, so as to form an involute on the surface of the impeller. The jig can conveniently realize the processing of the involute.
Description
Technical field
The utility model relates to a kind of anchor clamps, especially for the anchor clamps of roots blower rotor processing.
Background technology
Rotor is the vital part of roots blower, and it is made up of impeller and axle, and the section molded lines of impeller has involute-type, circular arc type, gerotor type and envelope line style etc.The number of sheets of impeller mostly is two leaves, also can make three leaves or leafy.Roots blower can be thought two special gear engagements of having only two or more teeth, realizes the revolution volume-variation.Because its curvilinear plane broad, required precision is high again, and it is very difficult to adopt forming-tool to process, and is difficult to reach machining accuracy.And adopt machining center to add man-hour, the processing cost height.
Summary of the invention
The purpose of this utility model provides a kind of roots blower rotor clamp for machining easy, that processing cost is low of processing.
Scheme of the present utility model is as follows: a kind of roots blower rotor clamp for machining, the two ends that it is characterized in that mandrel link to each other with bearing block, the mandrel projecting shaft bearing of an end and be installed with gear wherein, gear and the tooth bar engagement that is installed on the planer lathe bed, processed workpiece are installed on the mandrel between the diaxon bearing.
Between workpiece on the mandrel and bearing block, be set with axle sleeve.
Bearing block is fixedly mounted on the workbench of planer.
Characteristics of the present utility model are to utilize these anchor clamps can realize the processing of the involute impeller of roots blower rotor on planer.Adding the workpiece to be machined in man-hour---impeller is fixed on the workbench of planer by bearing block and mandrel, when workbench moves horizontally, mesh by the tooth bar that is installed in the gear on the mandrel and be fixedly mounted on the planer lathe bed, the impeller rotation, the compound motion that rotation forms of the rectilinear motion of planing tool and workpiece just can form involute in impeller surface like this.Because it is fixing that workpiece to be machined positions by mandrel, in process, can guarantee that the pivot of workpiece overlaps with the pivot of mandrel, has improved the installation accuracy of process like this.Can conveniently realize the processing of involute by these anchor clamps.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, bearing block 4 is fixedly mounted on the workbench 6 of planer, the two ends of mandrel 8 are fixed on the bearing block 4, the mandrel left end is installed with gear 3, gear 3 is meshing with each other with the tooth bar 2 that is installed on the planer lathe bed 1, processed workpiece 5 is installed on the mandrel between the diaxon bearing, the mandrel right-hand member be set with axle sleeve 7, by axle sleeve with axial location between workpiece 5 and the bearing block 4.When the workbench of planer moves horizontally,, realized the rotation of workpiece by being meshing with each other of gear, tooth bar.
