Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece positioning, in particular to a radial drill steel pre-clamping mechanism. Background Art

[0002] A radial drilling machine is a drilling machine in which the rocker arm can rotate and rise and fall around the column, and the spindle box usually moves horizontally on the rocker arm.

[0003] When the radial drill is processing a long steel, it is necessary to perform equidistant drilling on the long steel.

[0004] During the processing, when the position of the steel needs to be adjusted, the position of the steel is changed by manually pushing and pulling the steel. Each movement will cause the axis position of the hole to be drilled on the steel to deviate from the radial drill bit, requiring repeated corrections, resulting in low steel processing efficiency.

[0005] Therefore, we propose a sample cutting machine to solve the existing problems. Utility Model Content

[0008] Preferably, a bolt is threadedly mounted on the side ring, and one end of the bolt passes through the side ring.

[0009] Preferably, roller grooves matching the lower rollers and upper rollers are respectively formed on the upper surface of the bed and the lower surface of the upper beam, and each of the lower rollers and upper rollers is rotatably mounted on each roller groove.

[0010] Preferably, the lifting assembly is composed of a chassis, a slide, a slider and a screw, the screw is rotatably installed in the back plate, the slide is opened in the middle position of the back plate, the slider is slidably installed in the slide and is in a threaded engagement state between the screws, and the other end of the slider is fixed to the upper beam.

[0013] Preferably, the lower surface of the bed is provided with supporting feet, and the supporting feet are distributed in a rectangular array on the lower surface of the bed.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The steel pre-clamping mechanism of the radial drill can place the long-distance steel to be processed on the bed, and then control the upper beam to move downward through the lifting assembly, so that the upper roller and the lower roller clamp the steel. At this time, the distance between the side rings of the upper roller and the lower roller is adjusted according to the width of the steel, so that each side ring is against the side of the steel, and the steel is limited in the vertical direction by the upper roller and the lower roller, and the steel is limited in the horizontal direction by the side ring;

[0016] At this time, the personnel manually push the steel, and the steel can only move along a straight line to the radial drill bed surface, and then the position of the steel is fixed by the positioning structure on the radial drill, and finally the steel is drilled by the radial drill;

[0017] The utility model pre-clamps the steel by limiting the position between mechanical structures, forcing the steel to move only in a straight line, thereby preventing the axis position of the hole to be drilled on the steel from deviating from the rocker drill bit when the steel moves, thereby improving the processing efficiency of the steel.

The rollers 14 are between them, and each of the side rings 9 is on the side of the steel piece 3. The long-distance steel to be processed can be placed on the bed 1, so that the upper roller 14 and the lower roller 8 clamp the steel, and each of the side rings 9 is against the side of the steel. The steel is limited in the vertical direction by the upper roller 14 and the lower roller 8, and in the horizontal direction by the side rings 9. At this time, the steel is manually pushed, and the steel can only move along a straight line to the radial drilling bed surface 7, and the radial drill performs equidistant drilling processing on the steel.

[0025] A bolt 10 is threadedly installed on the side ring 9, and one end of the bolt 10 passes through the side ring 9. When the position of the side ring 9 is determined, the bolt 10 is rotated so that the bolt 10 abuts against the surface of the lower roller 8 and the upper roller 14, thereby fixing the position of the side ring 9.

Through the cooperation of the above structure, an external power supply is connected so that the motor drives the screw 13 to rotate. Under the action of the screw principle, the rotation of the screw 13 can be converted into the lifting action of the slider 12.
