Abstract
The invention relates to a mechanical machining method and provides a machining method for axle holes of a cross beam body of a press machine. The method comprises the following steps of: carrying out heavy boring on each axle hole; carrying out fine boring on technology holes; installing shaft sleeves and mandrels in the technology holes; regulating a boring rod and mandrels to be coaxial; regulating central distances of the machined axle holes and the machined technology holes; and starting up and machining. The machining method can ensure the coaxiality and the depth of parallelism of the axle holes when being used for machining the axle holes of the cross beam body of the press machine, so that the rear-stage assembling of the press machine is more time-saving and labor-saving, the engagement among gears is good, and the operation precision of the press machine is improved effectively.
Description
Technical field
The present invention relates to a kind of machining process, be specifically related to the processing method in a kind of pressure machine cross-beam axon hole.
Background technology
The development of current automobile manufacture industry is maked rapid progress, so that the demand of the technology of process equipment and quantity improves constantly, provides the forcing press of strong backing more and more important as automobile manufacture industry.The running accuracy of forcing press has been directly connected to quality, precision and the mold use life-span of stamping parts.The precision of the performance of forcing press and its cross girder upper shaft hole has direct relation, the cross girder appearance and size of forcing press is larger, cross girder high speed shaft, jackshaft, slow-speed shaft are the gear engagement, its axis hole is many rows at pressure machine cross-beam to be arranged, and adds axiality and the depth of parallelism that must guarantee each axis hole man-hour.
Summary of the invention
The purpose of this invention is to provide a kind of easy and simple to handle, processing method of being easy to grasp and can guaranteeing each axis hole axiality and depth of parallelism required pressure machine cross girder axis hole on the pressure machine cross-beam body.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is: the processing method in pressure machine cross-beam axon hole, it is characterized in that: the method comprises the following steps:
(1) according to drawing requirement each axis hole of assigned address heavy boring on the pressure machine cross-beam body, surplus is left in each axis hole aperture of heavy boring;
(2) according to the fabrication hole of drawing requirement 30-40mm of right boring on the cross girder assigned address;
(3) axle sleeve and mandrel are installed in fabrication hole;
(4) at the boring bar head dial gauge is installed, allow the dial gauge gauge outfit near mandrel, start machine tool boring bar, the dial gauge gauge outfit is rotated around mandrel, observe the dial gauge number of degrees, require indicator in 0.05mm, to fluctuate, if stirring, indicator exceeds 0.05mm, then need to shut down and adjust boring bar, realize that boring bar is coaxial with fabrication hole, thereby guarantee that other axis hole and fabrication hole are coaxial;
(5) mobile boring bar passes axis hole to the axis hole position that needs processing with boring bar, measures the distance L of mandrel and boring bar with inside micrometer
1, calculating axis hole and fabrication hole centre-to-centre spacing is L=L
1+ D
1/ 2+ D
2/ 2, D wherein
1Be axle diameter, D
2Be the boring bar diameter, if the L value is different from the drawing nominal value, then travelling table is adjusted, until the L value is consistent with the drawing nominal value, and this axis hole of start right boring;
(6) process finishing moves to next processing axis hole with boring bar, and repeating step 5 gets final product.
Beneficial effect of the present invention is: adopt processing method provided by the invention to pressure cross girder axis hole
Processing axiality, the depth of parallelism that can guarantee each axis hole, is that the later stage assembling of forcing press is more time saving and energy saving, and engagement property is good between the gear, the running accuracy of Effective Raise forcing press.
Description of drawings
Accompanying drawing the invention provides the schematic diagram that method is processed for adopting.
Among the figure, 1, cross girder, 2, axle sleeve, 3, mandrel, 4, axis hole, 5, boring bar, 6, inside micrometer.
The specific embodiment
Be described further below in conjunction with the processing method of accompanying drawing to pressure machine cross-beam axon provided by the present invention hole.
As shown in drawings, need to process several axis holes 4 on the cross girder 1, shown in the drawings of the axis hole 4 of 5 need processing.
As shown in drawings, according to these these 5 axis holes of the assigned address heavy boring of 5 axis hole positions on the pressure machine cross-beam body of drawings marked, surplus is left with respect to the standard aperture in each axis hole aperture behind the heavy boring first;
As shown in drawings, according to the fabrication hole of drawing requirement 30-40mm of right boring on cross girder 1 assigned address, axle sleeve 2 and mandrel 3 are installed in fabrication hole;
At the boring bar head dial gauge is installed, allow the dial gauge gauge outfit near mandrel, start machine tool boring bar, the dial gauge gauge outfit is rotated around mandrel, observe the dial gauge number of degrees, require indicator in 0.05mm, to fluctuate, if stirring, indicator exceeds 0.05mm, then need to shut down and adjust boring bar, realize that boring bar is coaxial with fabrication hole, thereby guarantee other axis hole and fabrication hole coaxial (this operation is not shown);
As shown in drawings, mobile boring bar 5 passes axis hole 4 to axis hole 4 positions of needs processing with boring bar 5, measures the distance L of mandrel 3 and boring bar 5 with inside micrometer 6
1, calculating axis hole and fabrication hole centre-to-centre spacing is L=L
1+ D
1/ 2+ D
2/ 2, D wherein
1Be axle diameter, D
2Be the boring bar diameter, if the L value is different from the drawing nominal value, then travelling table is adjusted, until the L value is consistent with the drawing nominal value, and this axis hole of start right boring;
This axis hole process finishing moves to next processing axis hole with boring bar, duplicate measurements axis hole to be processed and fabrication hole centre-to-centre spacing L, and adjustment makes that the L value is consistent with the drawing nominal value can carry out the processing of this axis hole.
The processing method that this invention provides is not limited to 5 axis hole processing shown in the present embodiment, and the method for a plurality of axis hole processing is consistent with said method.
