Technical Field
The utility model relates to the field of machinary, a go up unloading clamping machine structure specifically says so.
Background
Along with the improvement of the efficiency of the batch production of the machined parts, the loading and unloading mechanism also needs to be simpler, more convenient and faster, wherein the clamping mechanism of the workpiece is the most important part, and particularly, the loading and unloading of the workpiece are very difficult for the workpiece with a through hole with a small diameter (less than 9mm), so that the loading and unloading clamping mechanism with the small inner circle diameter and wide application range needs to be designed.
Disclosure of Invention
In order to solve the technical problem, the utility model aims at providing an go up unloading clamping machine and construct has simple structure, adapts to the requirement of circle diameter in the aperture.
The specific technical scheme is as follows:
the inner circle small-diameter feeding and discharging clamping mechanism is characterized in that a cylinder is fixed on a connecting fixing plate, and the piston end of the cylinder is connected with the upper end of an expanding core nail through threads; the lower end of the push expansion core nail is conical, the upper end of the hollow shaft expansion sleeve is fixed on the connecting fixing plate, the lower part of the hollow shaft expansion sleeve is provided with a plurality of groups of partition grooves, and the internal shape of the hollow shaft expansion sleeve is matched with the appearance of the push expansion core nail; a workpiece pop-up sleeve is arranged outside the hollow shaft expansion sleeve, a limiting ring is arranged outside the push expansion core nail, and an inner hexagonal socket head cap screw penetrates through a through hole in the upper part of the workpiece pop-up sleeve and a through hole of the hollow shaft expansion sleeve and then is connected with a screw hole in the side face of the limiting ring; and a spring is arranged on the outer side of the hollow shaft expansion sleeve connecting the fixed plate and the workpiece ejection sleeve.
The lower part of the hollow shaft expansion sleeve is provided with a plurality of uniform parts, and a separation groove is arranged between the adjacent parts.
The lower outline shape of the hollow shaft expansion sleeve is matched with the inner outline shape of the inner hole of the workpiece.
In the automatic loading and unloading clamping mechanism with the small inner circle diameter, the hollow shaft expansion sleeve is made of nylon materials.
The utility model has the advantages that: the hollow shaft expansion sleeve is made of nylon materials, so that scratches and collision damages of inner holes of workpieces are effectively reduced.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a profile connection;
FIG. 3 is a schematic cross-sectional view taken at the location of FIG. 1A-A;
in the figure, 1, a workpiece ejecting sleeve, 2, a hollow shaft expanding sleeve, 3, an expanding core pushing nail, 4, a limiting ring, 5, an inner hexagonal socket head screw, 6, a spring, 7, a connecting fixing plate and 8, a cylinder.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings, as shown in the drawings, the cylinder 8 is fixed on the connecting fixing plate 7, and the piston end of the cylinder 8 is connected with the upper end of the expanding core nail 3 through a thread 31; the lower end of the push expansion core nail 3 is conical, the upper end of the hollow shaft expansion sleeve 2 is fixed on the connecting fixing plate 7, the lower part of the hollow shaft expansion sleeve 2 is provided with a plurality of groups of dividing grooves 21, and the inner shape of the lower end of the hollow shaft expansion sleeve 2 is matched with the appearance of the push expansion core nail 3 and is conical; a workpiece pop-up sleeve 1 is arranged outside the hollow shaft expansion sleeve 2, a limiting ring 4 is arranged outside the push-expansion core nail 3 to ensure the radial positioning of the push-expansion core nail, and an inner hexagonal socket head cap screw 5 is connected with a screw hole on the side surface of the limiting ring 4 after passing through a through hole on the upper part of the workpiece pop-up sleeve 1 and a through hole of the hollow shaft expansion sleeve 2; a spring 6 is arranged on the outer side of the hollow shaft expansion sleeve between the connecting fixing plate 7 and the workpiece popping sleeve 1.
As shown in fig. 3, the hollow expansion sleeve 2 is divided into a uniform plurality of parts at the lower part, and a separation groove 21 is formed between the adjacent parts.
In order to adapt to workpieces with inner holes of different shapes, the lower outline shape of the hollow shaft expansion sleeve 2 is matched with the inner outline shape of the inner hole of the workpiece.
In order to ensure the elasticity, the hollow shaft expansion sleeve 2 is made of nylon.
The utility model discloses a use method is: the workpiece 9 is positioned below the workpiece pop-up sleeve 1, when the workpiece pop-up sleeve 1 is pressed downwards to the workpiece 9, the hollow shaft expansion sleeve 2 is inserted into a through hole of the workpiece 9, the workpiece pop-up sleeve 1 moves upwards to compress the spring 6, after the hollow shaft expansion sleeve 2 is inserted to a preset depth of the workpiece, the air cylinder pushes the piston to move downwards, the core pushing and expanding nail 3 moves downwards along with the downward movement and is abutted against a conical part on the inner side of the lower part of the hollow shaft expansion sleeve 2, and because the upper part of the hollow shaft expansion sleeve 2 is fixed on the connecting and fixing plate 7 and does not move, the lower part of the hollow shaft expansion sleeve 2 is pushed by the lower part of the core pushing and expanding nail 3 to expand outwards, so that the outer side of the lower part of the hollow shaft expansion sleeve 2 is abutted against the; otherwise, the piston of the cylinder contracts, the hollow shaft expansion sleeve 2 is loosened from the inner side of the inner hole of the workpiece, and the workpiece is released under the action of the spring. The fixing of the workpiece during moving is realized through the method.
