Abstract
The invention relates to a gravity center displacement balance device of a square ram of a main shaft box of a floor-type boring and milling machine. The balance device comprises a gravity hammer, a balance oil cylinder, a hydraulic proportioning valve and a numerical control system, wherein the balance oil cylinder is arranged on the front upper side of a power head case body, and the balance oil cylinder is connected with the gravity hammer through a plate type chain and connected with the numerical control system through the hydraulic proportioning valve. The balance device has a simple and reasonable structure, is convenient to operate, controls the oil pressure of the balance oil cylinder through the numerical control system, achieves the effect of controlling drop of the main shaft due to outward extension of the square ram under the action of the gravity hammer, improves the machining precision of equipment and ensures the precision of equipment.
Description
Technical field
The present invention relates to a kind of console mode boring and milling machine, specifically, relate to the displacement of center of gravity bascule of a kind of console mode boring and milling machine main spindle box side ram.
Background technology
At present, domestic console mode boring and milling machine has vast market, and the core position of console mode boring and milling machine is a unit head, and how its precision is concerning the precision of whole lathe.The side's of being equipped with ram in the unit head casing; Along with the difference of processing work, square ram need repeat overhanging and the expanding-contracting action of regaining, because of square ram dead weight very heavy; And its extension is different along with the difference of processing work; It is unbalance that this has just caused unit head on former balance basis, to occur, and sag appears in the side's of causing ram, has a strong impact on the machining accuracy of equipment.The present domestic multiple processing method that has, effect is all undesirable.
Summary of the invention
The objective of the invention is to existing provides a kind of solution simple in structure, effective because of the overhanging displacement of center of gravity bascule of the unbalance problem of unit head gravity afterwards of square ram because of workpiece difference side ram extension difference causes the problems referred to above such as unit head is unbalance.
Technical scheme of the present invention is: the displacement of center of gravity bascule of a kind of console mode boring and milling machine main spindle box side ram; This bascule comprises gravity drop hammer, balancing cylinder, hydraulic proportion valve and digital control system; Balancing cylinder is installed in the front upper place of unit head casing; Balancing cylinder links to each other with gravity drop hammer through board-like chain, and is connected with digital control system through hydraulic proportion valve.
Preferably, this bascule also is provided with a fuel tank, and this fuel tank is connected with balancing cylinder, is the balancing cylinder fuel feeding.
Preferably, hydraulic proportion valve is provided with an amplifier, and this amplifier is connected with digital control system.
Preferably, an end of board-like chain is connected with balancing cylinder, and the other end passes two sprocket wheels and is connected with gravity drop hammer.
The invention has the beneficial effects as follows: the present invention is simple and reasonable for structure; Easy to operate; Through the oil pressure of digital control system control balancing cylinder, and the effect through gravity drop hammer, realize that control side's ram is because of the overhanging main shaft sagging problem that causes; Improve the machining accuracy of equipment, guaranteed the precision of equipment simultaneously.
Description of drawings
Accompanying drawing 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
The displacement of center of gravity bascule of a kind of console mode boring and milling machine main spindle box side ram; This bascule comprises gravity drop hammer 1, balancing cylinder 2, hydraulic proportion valve 3 and digital control system; Balancing cylinder 2 is installed in the front upper place of unit head casing 4; Balancing cylinder 2 links to each other with gravity drop hammer 1 through board-like chain 5, and is connected with digital control system through hydraulic proportion valve 3.This bascule also is provided with a fuel tank 6, and this fuel tank 6 is connected with balancing cylinder 2, is balancing cylinder 2 fuel feeding.Hydraulic proportion valve 3 is provided with an amplifier, and this amplifier is connected with digital control system.One end of board-like chain 5 is connected with balancing cylinder 2, and the other end passes two sprocket wheels 8 and is connected with gravity drop hammer 1.
Operation principle: behind square ram 7 overhanging certain-lengths; Digital control system will be given aanalogvoltage of amplifier, by amplifier control hydraulic proportion valve 3, thus the oil pressure of control balancing cylinder 2; And the effect through gravity drop hammer 1, reach control side's ram 7 owing to overhanging cause sagging.
