Description
Technical field
The utility model relates to a kind of frock clamp, particularly relates to a kind of frock clamp automobile axle shaft being added to man-hour.
Background technology
The two ends of automobile axle shaft have centre bore to need grinding, two when carrying out lathe process to automobile axle shaft, general way adopts the direct clamping disk(-sc) portion of scroll chuck, and then hold out against the other end with thimble, there is following defect in this mode: it adopts manual operation scroll chuck to clamp, and operator's working strength is large, efficiency is low, and manual operation, exist individual differences factor cause insufficient clamping force and add man-hour occur loosen, affect crudy; Cannot ensure half shaft centre line and thimble on the same line in addition, cause machining benchmark to be forbidden, percent defective is higher.
Utility model content
Because the above-mentioned defect of prior art, when technical problem to be solved in the utility model is to provide a kind of automobile axle shaft two ends endoporus attrition process, can the positioning datum of unified automobile axle shaft, and can Quick-clamped, reduce clamping non-cutting time, the frock clamp of raising the efficiency.
For achieving the above object, the utility model provides a kind of frock clamp, it is characterized in that, comprises the base of fixture, the described left and right sides, base upper surface is provided with the left and right clamp structure of Parallel Symmetric; Described clamp structure comprises support cylinder that described base upper surface is fixedly connected with and two back-up blocks, locking briquetting, the support of inverted U, motor and screw mandrel; Described support cylinder top is provided with the first arc-shaped notch of clamping automobile axle shaft bottom; Two described back-up blocks are arranged on the both sides, front and back of support cylinder and symmetrical relative to support cylinder center line; The contiguous support cylinder side of two described back-up blocks is provided with the T-slot mouth of vertical direction; Two described back-up blocks are fixedly connected with away from the inner side of support cylinder side with inverted U support; Described motor is fixed on cradle top; Described motor output shaft is fixedly connected with screw mandrel upper end; Described screw mandrel lower end is connected with a joggle with the screwed hole of locking briquetting upper end; Described locking briquetting bottom is provided with second arc-shaped notch on clamping automobile axle shaft top; Described both sides, locking briquetting top are provided with the T-shaped projection coordinated with T-slot mouth.
Further, two described back-up blocks are deviated from support cylinder side and are fixedly connected with by screw with inside support two.
Compared to existing technology, the beneficial effects of the utility model are: it is simple that the utility model has structure, easy to operate, automatically can realize clamping, thus reduce labour intensity, raise the efficiency; Two the first arc-shaped notch of the Parallel Symmetric on two support cylinder tops are as positioning datum simultaneously, when on automobile axle shaft, two positions are compressed simultaneously, realize positioning datum unified, thus reduce the position error of central shaft on automobile axle shaft, improve crudy and production efficiency.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figures 1 to 6, a kind of frock clamp, is characterized in that, comprises the base 1 of fixture, the described left and right sides, base 1 upper surface is provided with the left and right clamp structure of Parallel Symmetric; Described clamp structure comprises support cylinder 2 that described base 1 upper surface is fixedly connected with and two back-up blocks 11, locking briquetting 4, the support 5 of inverted U, motor 6 and screw mandrel 7; Described support cylinder 2 top is provided with the first arc-shaped notch 21 of clamping automobile axle shaft 10 bottom; Two described back-up blocks 11 are arranged on the both sides, front and back of support cylinder 2 and symmetrical relative to support cylinder 2 center line; Contiguous support cylinder 2 side of two described back-up blocks 11 is provided with the T-slot mouth 31 of vertical direction; Two described back-up blocks 11 are fixedly connected with the inner side screw 15 of inverted U support 5 away from support cylinder 2 side; Described motor 6 is fixed on support 5 top; Described motor 6 output shaft is fixedly connected with screw mandrel 7 upper end; Described screw mandrel 7 lower end is connected with a joggle with the screwed hole 43 of locking briquetting 4 upper end; Described locking briquetting 4 bottom is provided with second arc-shaped notch 41 on clamping automobile axle shaft 10 top; Described both sides, locking briquetting 4 top are provided with coordinate with T-slot mouth 31 T-shaped protruding 42.
During use, as shown in Figures 1 to 6, base 1 is fixed on the workbench of attrition process lathe, automobile axle shaft 10 is placed in first arc-shaped notch 21 on two support cylinder 2 tops; Open two motors 6, motor 6 drives screw mandrel 7 to rotate by 7 output shafts, and then screw mandrel 7 lower end is connected with a joggle with locking briquetting 4 threaded upper ends; Screw mandrel 7 act under drive locking briquetting 4 on both sides T-shaped protruding 42 along T-slot 31 slide straight down; Finally make two the second arc-shaped notch 41 and two the first arc-shaped notch 21 that the top and the bottom at automobile axle shaft 10 two ends are all compressed, realize Automatic-clamping, then close two motors 6; Because the first arc-shaped notch 21 center of now two support cylinder 2 of fixture is coaxial with the alignment of shafts of lathe, and two the first arc-shaped notch 21 are fixed, so during automobile axle shaft clamping, the center line of the two ends endoporus on its automobile axle shaft 10 is all consistent with machine tool chief axis, therefore can guarantee the accuracy of its machining benchmark.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
