Description
Technical Field
The utility model relates to an anchor clamps, specifically speaking are tight work piece of clamp carry out the anchor clamps that the excircle ground to the work piece.
Background
In the prior art, an excircle grinding mandrel is usually designed for an excircle grinding tool for cake parts, a product is locked on the mandrel in a nut and gasket mode, and then the mandrels are tightly jacked by tops at two ends of a grinding machine for machining. However, in the conventional external grinding clamp, a certain gap exists between the tool and the product, which affects the machining precision of the product, and meanwhile, a lot of inconvenience is caused when the workpiece is assembled and disassembled. After the workpiece is clamped on the outer circle grinding clamp for rounding treatment, the workpiece is difficult to disassemble, and the whole assembly and disassembly are complicated.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides an external grinding fixture.
In order to solve the technical problem, the utility model discloses take following technical scheme:
the excircle grinding clamp comprises a mandrel fixedly connected with a machine tool, wherein an expansion sleeve is fixedly mounted on the mandrel, an expansion hole is formed in the expansion sleeve, a die sleeve is placed in the expansion hole, the die sleeve is provided with an extrusion hole convenient for tail cone extrusion, a screw hole penetrating through the die sleeve is formed in the die sleeve, a bolt is screwed in the screw hole, and the upper end of the bolt is exposed outside the die sleeve.
And a limiting block is arranged in the expansion sleeve and is positioned in the expansion hole area, and the bolt on the die sleeve is right opposite to the limiting block.
The expansion hole is in an inverted frustum shape, and the die sleeve is in a matched frustum shape.
The limiting block is connected with the expansion sleeve in a locking mode through a screw.
The limiting block is also provided with an elastic component, and the die sleeve is placed in the expansion hole and then abuts against the elastic component.
The elastic component is an elastic rubber block or a spring.
The utility model discloses utilize the die sleeve to receive the ejecting extrusion cover that expands in extrusion back to make the cover that expands extrude the work piece, fixed the work piece steadily, the rounding operation of the work piece of being convenient for, it is convenient to dismantle, circulated use.
Drawings
Fig. 1 is a schematic view of the cross-sectional structure of the workpiece assembly of the present invention.
Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in the accompanying drawing 1, the utility model discloses an excircle grinding clamp, include the dabber 1 with lathe fixed connection, there is the cover 2 that expands through screw fixed mounting in the dabber 1, and the hole of the cover 2 that expands and the excircle tight fit installation of dabber 1 have guaranteed that the tapering hole and the effect excircle of the cover 2 that expands are concentric with dabber 1, are equipped with the tapering hole in the cover 2 that expands, have placed die sleeve 4 in this tapering hole, and die sleeve 4 is equipped with the exhaust hole of the extrusion of the caudal vertebra of being convenient for, and the design has the screw that runs through this die sleeve in the die sleeve 4, installs bolt 7 in this screw, and bolt 7 upper end exposes in die sleeve 4 outsides. The workpiece 9 is sleeved on the expansion sleeve, after the die sleeve 4 is arranged in the expansion hole, the outer conical circle of the die sleeve 4 is matched with the inner conical hole of the expansion sleeve 2, the die sleeve 4 is extruded through the jacking force of the tail cone 8, and then the expansion sleeve 2 obtains outward expansion acting force, so that the expansion sleeve plays a stable fastening role on the workpiece. The dashed portion in fig. 1 is a workpiece.
The expansion sleeve 2 is internally provided with a limiting block 3, the limiting block 3 is positioned in an expansion hole area, a bolt on the die sleeve faces the limiting block, and the limiting block can prevent the extrusion stroke of the caudal vertebra from being too large, so that the expansion sleeve is deformed too much to damage a workpiece.
The expanding hole is in the shape of an inverted frustum, and the die sleeve is in the shape of a matched frustum, so that the extrusion deformation of the die sleeve is facilitated.
The limiting block 3 is connected with the expansion sleeve 2 in a locking mode through a screw 6, and installation and disassembly are convenient.
The limiting block 3 is further provided with an elastic component 10, and the die sleeve is placed in the expansion hole and then abuts against and presses the elastic component. The elastic component is an elastic rubber block or a spring. Along with the extrusion of caudal vertebra to the die sleeve, the die sleeve can be disconnected support against elastic component for elastic component produces the resilience, and behind the effort of cancellation caudal vertebra, the resilience force that elastic component produced can be bounced the stopper, helps taking out the die sleeve.
The utility model discloses in, place the compression mould cover in the tight hole that expands of cover, the work piece cover that will treat processing outside the cover expands, the dabber is fixed with the lathe, realizes holistic fixed Assembly. The extrusion piece caudal vertebra is crowded and is impressed in the die sleeve, continuous extrusion to form the extrusion effect that expands outward to the die sleeve, make the die sleeve outwards expand and form the effect that expands outward to the cover that expands, drive the cover that expands outwards, thereby play the fastening to the work piece. The workpiece can be rounded. After the machining is completed, the workpiece needs to be taken out at this time. The screw bolt is screwed to the bolt in the die sleeve to make the bolt move downwards continuously and the bolt is pushed upwards for ejection.
It should be noted that the above is only a preferred embodiment of the present invention, and the present invention is not limited to the above, and although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that the technical solutions described in the foregoing embodiments can be modified or some technical features can be replaced with equivalents, but any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
