Abstract
The invention relates to a ram assembly method, in particular to a ram assembly method for a multifunctional precise boring-milling machine. The method comprises the following steps: a, detecting deflection which is generated by the ram moving relatively to a sliding frame due to self weight; b, processing a spacer between the ram and the sliding frame according to the deflection detected in the previous step so that the upper surface of the spacer is an inclined surface; and c, mounting the spacer on the sliding frame so that the inclined surface of the spacer contacts with a friction surface at the bottom of the ram. The ram assembly method for the multifunctional precise boring-milling machine enables the spacer with the inclined surface to be mounted at the bottom of the ram so that a sliding track of the ram can gradually change upwards along with the increase of a sliding distance of the ram when the ram slids outwards if the self weight deformation of the ram is omitted. In fact, due to the influence of the self weight deformation of the ram, the gradually upward change amount of the ram along with the increase of the sliding distance of the ram just counteracts the self weight deflection so as to improve the processing precision of equipment.
Description
Technical field
The present invention relates to a kind of assembly method of ram, particularly a kind of ram assembly method for multifunctional precise boring-milling machine.
Background technology
Ram is parts commonly used in the machining apparatus, and ram can reciprocatingly slide with respect to the balladeur train on the lathe at work.When sliding with respect to balladeur train error can appear as the horizontally disposed ram of existing multifunctional precise boring-milling machine, its reason is because the ram deadweight produces, when ram slides into ultimate range, the deflection maximum that the ram front end is downward, this deflection increases and increases along with sliding distance.Owing to the existence of this deflection, had a strong impact on the machining accuracy of equipment.
Summary of the invention
The purpose of this invention is to provide and a kind ofly eliminate ram, overcome the deficiencies in the prior art owing to the deflection that deadweight is produced, improve the ram assembly method for multifunctional precise boring-milling machine of machining accuracy.
Ram assembly method for multifunctional precise boring-milling machine of the present invention is characterized in that: comprise the steps:
A, the deflection that is produced owing to deadweight when the detection ram moves with respect to balladeur train;
B, according to the adjusting pad between deflection that above-mentioned steps detected processing ram and the balladeur train, make to be the inclined plane above the adjusting pad;
C, adjusting pad is installed on the balladeur train, the inclined plane above the adjusting pad is contacted with the attrition surface of ram bottom.
The detection of wherein said deflection is that the multifunctional precise boring-milling machine column is moved to vertical workbench centre position, at the anterior saddle of ram place by the fixing amesdial of support, workbench is provided with leveling ruler and amesdial matches, and mobile ram also writes down the amesdial reading and measures described deflection.
The processing of wherein said adjusting pad is that adjusting pad is fixed on the flat mill pad tire, the one end pad that will grind the pad tire according to deflection rises, make the bottom surface and the horizontal plane of mill pad tire form the oblique angle, filled up height and adapted, utilized grinding machine processing to grind plane on the adjusting pad of pad tire top with deflection.
Ram assembly method for multifunctional precise boring-milling machine of the present invention, because the adjusting pad on inclined plane is arranged in the ram bottom surface, when ram outwards slides, if ignore ram deadweight distortion, the increase that the track that ram slides should be along with the ram sliding distance upwards changes gradually, but the influence of ram deadweight distortion is in fact arranged,, improved the machining accuracy of equipment along with the amount that the increase of ram sliding distance upwards changes has gradually just been offset the deadweight deflection.
Description of drawings
Fig. 1 is the structural representation of multifunctional precise boring-milling machine of the present invention;
Fig. 2 is the structural representation of processing adjusting pad on mill pad tire.
The specific embodiment
As shown in Figure 1, 2: step is as follows:
A, the deflection that is produced owing to deadweight when detection ram 2 moves with respect to balladeur train 4 earlier; Detection method is: multifunctional precise boring-milling machine column 1 is moved to vertical workbench centre position, at ram 2 anterior saddle places by the fixing amesdial 6 of support, workbench is provided with leveling ruler 5 and matches with amesdial 6, and mobile ram 2 and the reading that writes down on the amesdial 6 measure the downward deflection that ram 2 outwards slides and produced owing to deadweight.
B, according to the adjusting pad 3 between deflection that above-mentioned steps detected processing ram 2 and the balladeur train 4, making above the adjusting pad 3 is the inclined plane.Wherein adjusting pad 3 is four settings at interval.The processing method of adjusting pad 3 is: utilize screw that adjusting pad 3 is fixed in the place, last plane of flat mill pad tire 7, the adjusting pad 3 of the leftmost side is identical with the distance that is installed on the multifunctional precise boring-milling machine balladeur train 4 with distance between the adjusting pad 3 of the rightmost side; The one end pad that will be fixed on the mill pad tire 7 on the Grinder bench according to the above-mentioned deflection that records rises, make the bottom surface and the horizontal plane of mill pad tire 7 form oblique angle B, filled up height and adapted, utilized grinding machine processing to grind plane on the adjusting pad 3 of pad tire 7 tops with deflection.
C, adjusting pad is installed on the balladeur train, the inclined plane above the adjusting pad is contacted with the attrition surface of ram bottom.
Because adjusting pad 3 is to process on the mill pad tire 7 that tilts, when the bottom surface of adjusting pad 3 is in level on balladeur train 4, plane then is an inclined plane on it, install when back ram 2 outwards slides on adjusting pad 3 and offset the downward distortion that is produced owing to the ram deadweight, improved the machining accuracy of equipment.
