Abstract
The invention discloses an automatic knife-forging unloading device for processing a central main spindle, which comprises a main spindle arranged on a main spindle box by a bearing; a central spindle is arranged in the main spindle, the lower end of the central spindle is fitted with a broach mechanism, and a knife-forging cylinder is arranged above the central spindle; the lower end of a piston rod fitted with the knife-forging cylinder is connected with a top pressing end, and a disc spring in the main spindle is sleeved outside the central spindle; the knife-forging cylinder is fixedly connected to an unloading seat, and a guide rod is fixed on the main spindle box and fitted with the unloading seat; the unloading seat is pressed on the main spindle box by a spring sleeved on the guide rod, and the upper end of the main spindle is fixedly connected with an unloading disc, and a gap is formed between the part below the outer side of the upper end of the unloading disc and the part above a step in the unloading seat. In the process of forging a knife, the main spindle of the device does not bear frequent axial forces, thereby prolonging the service time of the bearing of the main spindle and reducing the operation cost.
Description
Technical field
The present invention relates to a kind of Mechanical Processing Center main shaft with the relief arrangement of forging a knife automatically.
Background technology
The machining center main shaft is that main spindle box is arranged with the relief arrangement structure of forging a knife automatically at present, by bearing main shaft is installed on the main spindle box, be provided with mandrel in the main shaft, the lower end and the tool-broaching mechanism of mandrel match, there is the dish spring to be sleeved on the mandrel outside in the main shaft, the oil cylinder of forging a knife on main spindle box above the mandrel, the piston-rod lower end head that matches with the oil cylinder of forging a knife connects the roof pressure termination.When forging a knife, the oil cylinder piston bar of forging a knife moves down, roof pressure termination roof pressure mandrel upper end, and the axial force that mandrel is born can be applied on the main shaft bearing, and main shaft bearing frequently is subjected to the active force of knife striking cylinder, has a strong impact on the service life of main shaft bearing.
Summary of the invention
The machining center main shaft that when the purpose of this invention is to provide a kind of mandrel and being subjected to roof pressure, main shaft bearing is not subjected to axial force, can prolong main shaft bearing service life, reduce maintenance time, reduce production costs overcomes the deficiencies in the prior art with the relief arrangement of forging a knife automatically.
Machining center main shaft of the present invention is with the relief arrangement of forging a knife automatically, comprise by bearing and be installed in main shaft on the main spindle box, be provided with mandrel in the main shaft, the lower end and the tool-broaching mechanism of mandrel match, the oil cylinder of above mandrel, forging a knife, the piston-rod lower end head that matches with the oil cylinder of forging a knife connects the roof pressure termination, there is the dish spring to be sleeved on the mandrel outside in the main shaft, the described oil cylinder of forging a knife is fixedly connected on the off-load seat, be fixed with guide post on main spindle box, guide post and off-load seat match, and the spring that is sleeved on the guide post is pressed in the off-load seat on the main spindle box, main shaft upper end is fixedly connected with the off-load dish, the outside, upper end of off-load dish following and above the off-load seat inner side step between gapped.
Machining center main shaft of the present invention is with the relief arrangement of forging a knife automatically, when forging a knife, because the off-load seat is not fixedlyed connected with main spindle box, the off-load seat overcomes upwards action of spring force, thereby the upper end outside of having eliminated the off-load dish is following and above the off-load seat inner side step between the gap, main shaft off-load dish and off-load seated connection are touched, active force is not passed to main shaft bearing, after the action of forging a knife is finished, the oil cylinder piston counteragent of forging a knife, thereby the action downwards under the effect of spring force of off-load seat makes main shaft off-load dish and off-load seat produce the gap, finishes the action of forging a knife, and main shaft runs well, in the process of forging a knife, main shaft does not bear frequent axial force, thereby prolongs the service life of main shaft bearing, has reduced operating cost.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention;
The specific embodiment
As shown in Figure 1: 10 is main spindle box, on main spindle box 10, main shaft 9 is installed by rack sleeve 8 and lower bearing 6, intermediate bearing 7, upper bearing (metal) 15,9 endoporus places are equipped with mandrel 11 at main shaft, and the lower end of mandrel 11 and tool-broaching mechanism 16 match, and tool-broaching mechanism 16 is used for installing or unloading bottom tool.The oil cylinder 1 of forging a knife above mandrel 9, the piston-rod lower end head thread that matches with the oil cylinder 1 of forging a knife is connected with roof pressure termination 2.Dish spring 5 is arranged in the main shaft 9, and dish spring 5 is sleeved on the outside of mandrel 11.The oil cylinder 1 usefulness bolt fixed mode of forging a knife is connected on the off-load seat 4, on main spindle box 10, be fixed with guide post 12, between guide post 12 and the main spindle box 10 for being threaded, hole on guide post 12 and the off-load seat 4 matches, there is pole cap the upper end of guide post 12, and the spring 13 that is sleeved on the guide post 12 is pressed in off-load seat 4 on the main spindle box 10.Main shaft 9 upper end bolts are fixedly connected with off-load dish 14, the outside, the upper end of off-load dish 14 following and above off-load seat 4 inner side step between gapped 3.
When forging a knife, because off-load seat 4 is not fixedlyed connected with main spindle box 10, off-load seat 4 overcomes the upwards action of elastic force of spring 13, thereby the upper end outside of having eliminated off-load dish 14 is following and above off-load seat 4 inner side step between gap 3, main shaft off-load dish and off-load seated connection are touched, active force is not passed to each bearing that main shaft is installed, after the action of forging a knife is finished, the oil cylinder piston counteragent of forging a knife, thereby off-load seat 4 action downwards under the effect of spring 13 makes main shaft off-load dish 14 and off-load seat 4 produce gap 13, finish the action of forging a knife, main shaft 9 can run well.
