The utility model belongs to ordinary drilling and milling machine, involving the bed, slide, ram, universal milling head structure optimization and upgrading.
At present, the domestic drilling and milling machine presents many varieties, many styles, but the overall rigidity of the machine is not ideal, simple structure, small processing range, processing is not flexible, poor machine stability. The universal rotary milling head mechanism of the invention can realize multi-angle machining completely, the processing flexibility is increased, the processing range is greatly increased, and the column mechanism adopts multi-stage gear transmission mode, which can realize 12 speed change and can meet various processing speed requirements. Sliding box through the multi-stage gear drive can achieve multi-stage speed, can adapt to a variety of processing speed requirements.
The contents of the invention
In view of the above shortcomings, the utility model provides the improvement measures. Can make the milling machine to maximize the processing advantages.
The technical scheme of the utility model is a universal rotary head drilling and milling machine, which comprises a base mechanism 1, a pillar mechanism 2, a lifting slide mechanism 3, a swing slide mechanism 4, a table mechanism 5, a ram box mechanism 6, A head mechanism 7, a rocker arm and an operation panel mechanism 8, a power distribution system mechanism 9, an embedded walker mechanism 10, and a slide seat mechanism.
Characterized in that the pillar mechanism 2 is located above the base mechanism 1 and is fixed with six screws. The lifting and lowering carriage mechanism 3 is supported by a rectangular dovetail and fixed to the pillar mechanism 3 by means of a pressing plate which can be moved up and down on the column guide rail by a vertical guide rail driven by an elevating screw. The rotary carriage mechanism 4 is fixed to the lifting carriage mechanism 3 by means of a dovetail fit, and the rotary carriage is fixed together with the lifting slide through the press plate, and the rotary carriage can be moved forward and backward by the horizontal screw drive. The table mechanism 5 is fixed to the swivel slide 4 by means of a 55 degree swallows fit and the longitudinal extension of the table is achieved by means of a longitudinal screw. The ram mechanism 6 is fixed to the ram seat mechanism 11 by means of a 55-degree dovetail fit, and a sliding groove is applied to form a rectangular groove in which the linear rack is fitted in and out of the groove through a gear shaft fixed to the seat To achieve the front and rear movement of the ram. The universal milling head mechanism 7 is fixed to the ram mechanism 6 by means of a rotary disk.
The utility model has the advantages of:
1, pillar body 2 with four-axis multi-stage gear transmission, through the gear with the milling can be achieved 12-level speed, greatly meet the customer’s processing needs, flexible processing methods. The overall height of the column to achieve Z to increase the trip to increase the scope of processing.
2, lift the slider body 3 in the original slide on the basis of the front end of a gap to accommodate the submerged knife device. The swing carriage mechanism 4 is divided into upper and lower parts by means of four T-bolts connected to each other and can achieve around 45 degrees rotation, so that processing range and processing capacity greatly enhanced.
3, the table body 5 lengthened, so that X to increase the trip to achieve the scope of processing increased.
4, the sliding box mechanism 6 adopts the gear transmission form, there are multi-level gear drive can achieve 12 speed, the bottom of the slide box has a vertical motor connected to provide power, greatly increasing the processing flexibility, fast and stable Sex. The lower part of the box through the 55-degree dovetail way with the ram seat with a rectangular groove in the tail surface, the embedded in a straight row of racks, fixed on the seat by the gear shaft and the meshing of the rack to achieve the front and rear movement.
5, the universal milling machine body 7 with the mutual cooperation of the two can rotate each other through the 90 degrees of a pair of chrysanthemum bevel gears to achieve transmission, can achieve any angle of space processing needs, processing flexible and fast. The universal head is fixed to the front end of the ram by means of a connecting plate which connects the gears in the ram box with the gears in the universal head through a spline shaft.
6, rocker arm with multi-section welded steel forming, through the square flange fixed in the top of the column behind. Operation box with 45 degrees backward tilt produced, beautiful appearance, the top through a flange and rocker connection. Bakelite U-type fixed in the lower part of the operation box, easy to drag and drop operation.
7, the distribution system is the entire machine tool power supply system, the use of electrical components fixed to galvanized steel plate, the entire electric plate fixed in the lower part of the column.
