A plurality of parts can be positioned and processed by one-time clamping through one set of clamp, the influence of human factors on the product quality is greatly reduced, the product quality is stable, the efficiency is obviously improved, the technical requirements on the professional of operators are obviously reduced, and the fixture has reference significance on the design of other product tools.

Description

Clamp for high-precision hole machining of universal shaft parts
Technical Field
The utility model belongs to the field of clamp machining, and relates to a clamp for machining high-precision holes of universal shaft parts.
Background
When a high-precision hole of a universal shaft part is processed in a machining center, the part is small, the precision requirement is high, the clamping is complex, the center needs to be corrected again in each machining process, the clamping efficiency is extremely low, the clamping is extremely unstable, and the requirement on the professional level of workers is high.
Disclosure of Invention
The purpose of the utility model is as follows: the utility model provides an anchor clamps that is used for universal axle class part high accuracy spot facing work, positioning accuracy is high, and the clamping is rectified conveniently, and a plurality of parts can be processed in clamping correction, reduce the influence of human factor to product quality.
The technical scheme of the utility model is as follows:
a clamp for processing high-precision holes of universal shaft parts comprises a base and a pressing plate; the base is provided with a universal shaft placing notch, the shapes of two ends of the notch are matched with the shape of a ball head of the universal shaft, and the middle section of the notch is a straight groove; the pressure plate is fastened on the straight groove A of the base through screws.
And cutter avoiding holes are respectively formed in the bottoms of the two ends of the notch.
The shape of the pressure plate is matched with that of the cylindrical section of the universal shaft.
The clamps may be arranged in a plurality of rows and columns.
And the base is provided with a clamp correcting hole.
One end of the notch is set to be a straight groove B.
The width of the straight groove B is larger than that of the straight groove A and is determined according to the shape of the universal shaft part.
And a gasket is arranged between the pressure plate and the screw.
The utility model has the beneficial effects that: this kind of universal shaft class part high accuracy spot facing work anchor clamps adopts the mode that two spheres compress tightly with the terminal surface location axle journal, convenient operation, and the practicality is strong, and positioning accuracy is high, and the centre gripping is stable, the not hard up phenomenon can not appear. A plurality of parts can be positioned and processed by one-time clamping through one set of clamp, the influence of human factors on the product quality is greatly reduced, the product quality is stable, the efficiency is obviously improved, the technical requirements on the professional of operators are obviously reduced, and the fixture has reference significance on the design of other product tools.
Description of the drawings:
FIG. 1 is a schematic structural diagram of a fixture for high-precision hole machining of universal shaft parts;
wherein, 1-base, 2-pressing plate.
Fig. 2 is a structural view of a multi-row and multi-column expansion jig of the jig shown in fig. 1.
Detailed Description
The following provides a more detailed description of the present invention through its specific embodiments.
As shown in fig. 1, comprises a base 1 and a pressure plate 2; the base 1 is provided with a universal shaft placing notch, the shapes of two ends of the notch are matched with the shape of a ball head of the universal shaft, and the middle section of the notch is a straight groove; the pressure plate 2 is fastened on the straight groove A of the base 1 through screws.
The bottom at notch both ends is equipped with the cutter respectively and dodges the hole, when processing work piece perforating hole, can avoid the cutter, reduces cutter wearing and tearing.
The appearance of the pressing plate 2 is matched with that of the cylindrical section of the universal shaft, so that the universal shaft can be better pressed, and the stability of clamping and positioning is ensured.
The clamp can be arranged in a multi-row and multi-column mode, and the working efficiency is improved according to the processing requirement.
The base 1 is provided with a clamp correcting hole for aligning the clamp and realizing one-time clamping correction processing of a plurality of parts.
One end of the notch can be set to be a straight groove B, so that the positioning is prevented from being exceeded, and various parts can be machined.
The width of the straight groove B is larger than that of the straight groove A and is determined according to the shape of the universal shaft part.
A gasket is arranged between the pressing plate 2 and the screw, so that the pressing plate is stressed more uniformly, and parts are not easy to wear.
The workpiece is placed on a notch of a base 1, circumferential positioning is achieved through circumferential positioning faces at two ends of the notch, one end of the workpiece is arc-shaped and straight-face combined to prevent over positioning, end face positioning is achieved on the bottom face of the notch, the workpiece is fixed in the notch of the base 1 through a pressing plate 2, a gasket and a screw, one clamp can clamp a plurality of parts at a time, the position of the clamp is aligned through a clamp correction hole, and the bottom end face of the notch of the base 1 is designed with a cutter avoiding hole to reduce cutter abrasion.
