Description

Chuck vertical fixing seat

Technical Field

The utility model belongs to the technical field of mechanical equipment, and particularly relates to a chuck vertical fixing seat.

Background

In the field of machining, there are many sets of inner holes of workpieces to be inserted and cut into key slots, and the prior clamping of the sets of workpieces is to fix a flat-nose pliers for machine on a machine tool workbench, then to clamp two end faces of a phi 250 chuck by the flat-nose pliers for machine, and then to clamp the sets of workpieces on the chuck. The flat jaw phi 250 chuck has a small area on both end faces due to interference from chuck jaws, thereby creating the following disadvantages: firstly, rigidity is not enough, shivering and jumping knife phenomenon is easy to generate when the key groove of the workpiece is inserted and cut, the roughness of each surface of the processed key groove cannot meet the requirement, and the cutting edge is easy to damage. Secondly, the vertical precision of the jaw of the flat tongs is affected, so that the perpendicularity error of the clamped chuck end face is large, the depths of two ends of a key slot cut out by slotting are inconsistent, and the requirements of a workpiece drawing are not met.

Part description: 1. the device comprises a seat body, 2, socket head cap screws I and 3, a scale ring, 4, a chuck, 5, a flat key, 6, a shaft sleeve, 7, a circular sleeve pad, 8, socket head cap screws II and 9, a positioning key, 10, a locking nut, 11, socket head cap screws III and 12, a handle, 13, a hexagonal nut, 14, a gasket, 15, a T-shaped bolt, 16 and a machine tool workbench.

Description of the embodiments

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-2: the utility model provides a perpendicular fixing base of chuck, includes pedestal 1, be equipped with axle sleeve 6 in the pedestal 1 centre bore, be equipped with scale ring 3 on the step of axle sleeve 6 left side department, be equipped with chuck 4 through socket head cap screw I2 on the tang bench of scale ring 3 left end, be equipped with flat key 5 on the axle sleeve 6 excircle, axle sleeve 6 pass through flat key 5 with precision clearance fit of pedestal 1, axle sleeve 6 right-hand member is equipped with the external screw thread, is equipped with round sleeve pad 7 and lock nut 10 through the external screw thread, lock nut 10 right-hand member face one side be equipped with handle 12 size matched with open slot, handle 12 foraminiferous one end is equipped with the open slot through socket head cap screw III 11, and pedestal 1 below both ends are equipped with T-shaped open slot, are equipped with location key 9 through socket head cap screw II 8 in the open slot.

The using method comprises the following steps: the lower surface of the base 1 is placed in a proper position on a machine tool workbench, and the left vertical surface of the base 1 faces the machine tool rest. The positioning key 9 below the positioning key is placed in a T-shaped groove in the middle of a machine tool workbench 16, the T-shaped bolt 15 is placed in the T-shaped groove in the middle of the machine tool workbench and the opening groove of the base body 1, and the hexagonal nut 13 is screwed to fix the base body 1.
