SUMMERY OF THE UTILITY MODEL

The utility model designs a set of marking off clamp aiming at various complex parts, one end of which adopts a three-jaw chuck structure and is used for clamping revolving body shaft parts, and the other end of which adopts a square box structure with a T-shaped groove and a V-shaped groove and is used for clamping plane parts and parts with special shapes; the marking clamp can rotate along two axes which are vertical to each other, the part rotating angle clamped by the three-jaw chuck and the square box is driven by the three-jaw chuck and the square box, and each rotating part is provided with scales, a pointer and a locking mechanism, so that the accuracy and the stability of turning are ensured, and the marking work of various types of parts can be smoothly completed.

The technical scheme of the utility model as follows:

a rotary composite marking clamp comprises a three-jaw chuck, a main body piece, a turnover shaft, a main body turnover switch, a pointer, a square box with a groove, a main body turnover piece and a base.

The three-jaw chuck is a clamping shaft part and can rotate along the axis; the three-jaw chuck is fixed at one end of the main body piece, and the other end of the main body piece is connected with the square box with the groove through the turnover shaft. The lower end of the main body part is fixed on the base through the main body overturning part. The dial is fixed on one side of the outer surface of the base. The inner side of the three-jaw chuck is provided with an angle.

The main body piece is a main body structure supporting part; the rotating shaft can rotate along the axis to drive the three-jaw chucks at the two ends and the square box to rotate; the main body overturning switch is internally provided with a gear structure and used for controlling the main body overturning part and the main body part to rotate; the pointer is fixed above the main body piece and used for determining the angle of the three-jaw chuck during rotation; the locking pin is arranged on the main body piece and used for locking the rotating state of the turnover shaft; the square box with the grooves is used for clamping plane parts and parts with special shapes;

the lower end of the main body overturning piece is of a rack structure and can rotate along the Y axis to drive the three-jaw chuck and the square box to rotate; the dial plate determines the rotation angle of the main body overturning piece; the base is used as a supporting piece and is matched with the main body overturning piece to rotate.

The utility model has the advantages that:

the clamp can complete the marking process of each angle and each surface of the part by one-time clamping, reduces the number of clamping teeth, is easy to realize reference unification, simplifies the marking work of the part with complex appearance, reduces the marking error, has stable state and greatly improves the accuracy of the marking process.

Detailed Description

The invention will now be further described with reference to the accompanying drawings

A rotary composite marking clamp comprises a three-jaw chuck 1, a main body part 2, a turnover shaft 3, a main body turnover switch 4, a pointer 5, a square box with a groove 7, a main body turnover part 8 and a base 10.

The three-jaw chuck 1 is a clamping shaft part and can rotate along the axis; the three-jaw chuck 1 is fixed at one end of the main body piece 2, and the other end of the main body piece 2 is connected with a square box 7 with a groove through a turnover shaft 3. The lower end of the main body part 2 is fixed on a base 10 through a main body overturning part 8. The dial plate 9 is fixed on one side of the outer surface of the base 10. The inner side of the three-jaw chuck 1 is provided with an angle.

The main body part 2 is a main body structure supporting part; the rotating shaft 3 can rotate along the axis to drive the three-jaw chucks at the two ends and the square box to rotate; the main body overturning switch 4 is internally provided with a gear structure and used for controlling the main body overturning part and the main body part to rotate; the pointer 5 is fixed above the main body piece 2 and is used for determining the angle of the three-jaw chuck during rotation; the locking pin 6 is arranged on the main body piece 2 and used for locking the rotating state of the turnover shaft; the square box with the grooves 7 is used for clamping plane parts and can also clamp parts with special shapes;

the lower end of the main body overturning part 8 is of a rack structure and can rotate along a Y-axis figure 3 to drive the three-jaw chuck and the square box to rotate; the dial 9 determines the rotation angle of the main body turnover piece; the base 10 serves as a support member to rotate in cooperation with the main body turning member.

This structure utilizes three-jaw (holding) chuck and square chest structure, carries out multi-functional clamping to the part, and the arbitrary one end of manual rotation can rotate in a flexible way, confirms accurate angle according to scale and pointer accuse, uses the fitting pin locking service position, both can realize on all kinds of parts the line process of circular, fillet class, can realize the multi-angle line process of complicated appearance part again.
