Abstract
The utility model relates to the technical field of shaft machining, in particular to a concentric grinding fixture. The concentric grinding fixture comprises a speed reducing box, wherein a transmission motor is arranged on the back surface of the speed reducing box, two rotating wheels are horizontally arranged on the front surface of the speed reducing box, and the speed reducing box is provided with a support frame. A pressing wheel and a control mechanism are arranged at one end of the support frame, and the other end of the support frame is connected with the speed reducing box in a hinged mode. The speed reducing box is provided with a backing which can move in the longitudinal direction. According to the concentric grinding fixture, a circle center of a product shaft is positioned in a three-point mode through the double rotating wheels and the pressing wheel, and the rotating wheels drive the product shaft to autorotate. The concentric grinding fixture is machined on the same base surface through the product shaft, and the machining requirement of the concentricity and the surface smoothness of the product shaft is met.
Description
Technical field
The utility model relates to the axle processing technique field, particularly a kind of concentric grinding jig.
Background technology
Grinding is mainly carried out at cylindrical grinder with one heart, in order to outside cylinder, outer cone and the shaft shoulder end face of grinding shaft-like workpiece, but the inefficiency of cylindrical grinder, machining accuracy is not high, and product clamping trouble is so that the cost of peripheral milling is high; In order to address the above problem, generally adopt the fixing mode of corresponding anchor clamps in the production and processing.
The utility model content
The purpose of this utility model is to provide a kind of compact conformation, easy to operate for the defective of prior art and deficiency, a kind of concentric grinding jig that machining accuracy is higher.
For achieving the above object, the utility model is by the following technical solutions:
A kind of concentric grinding jig described in the utility model, comprise reduction box, the described reduction box back side is provided with driving motor, the reduction box front is provided with symmetrical two runners, and described reduction box upper surface vertically has groove, and described groove center line is between two runners, the surface is lower than respectively outer rim on two runners about groove, reduction box is provided with fixed mechanism, and fixed mechanism one end is provided with the pinch roller that cooperates with runner, but is provided with the backer of longitudinally-moving in the groove of reduction box.
Further, described fixed mechanism comprises support, and described support one end is provided with depression bar, and the support other end and reduction box are hinged.
Further, the cross section of described runner is I shape, and two runners are in the same way interlock setting.
Further, described pinch roller vertically is located between the flange of runner.
The utility model beneficial effect is: the utility model is by the center of circle of double runner and pinch roller three-point fix product axle, and the rotation of driven by rotating wheel product axle is processed at same basal plane by the product axle, satisfies the processing request of product shaft concentricity and surface smoothness.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Among the figure:
1, driving motor; 2, reduction box; 3, depression bar; 4, support;
5, pinch roller; 6, product axle; 7, runner; 8, backer.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of concentric grinding jig described in the utility model, comprise reduction box 2, described reduction box 2 back sides are provided with driving motor 1, reduction box 2 fronts are provided with symmetrical two runners 7, described reduction box 2 upper surfaces vertically have groove, described groove center line is between two runners 7, the surface is lower than respectively outer rim on two runners 7 about groove, reduction box 2 is provided with fixed mechanism, fixed mechanism one end is provided with the pinch roller 5 that cooperates with runner 7, but is provided with the backer 8 of longitudinally-moving in the groove of reduction box 2; Described fixed mechanism comprises support 4, and described support 4 one ends are provided with depression bar 3, and support 4 other ends and reduction box 2 are hinged.
Above-mentioned modular construction the utility model agent structure
The cross section of described runner 7 is I shape, and two runners 7 are in the same way interlock setting; Described pinch roller 5 vertically is located between the flange of runner 7.
Operation principle: product axle 6 is placed reduction box 2 grooves, product axle 6 processing ends place the upper outer rim otch of two runners 7, support 4 drives pinch roller 5 downwards and cooperates radially fixed product axle 6 with runner 7, backer's 8 axial restraint product axles 6 other ends, open driving motor 1 and drive runner 7 by reduction box 2 speed changes, make product axle 6 low speed rotation, open grinding machine and carry out grinding.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
