Abstract
The utility model provides a main shaft unclamping device capable of repositioning and the main shaft unclamping device capable of repositioning is used for a digital processing center. An unclamping cylinder is equipped with an unclamping rod. The unclamping rod is straightly opposite to the center of a main shaft of a main shaft box. An installation plate is fixed on the main shaft box. The installation plate connects with the unclamping cylinder integrally. A spring return device is installed on the installation plate. A support rod of the spring return device is fixed on the installation plate. A spring is sleeved on the support rod. A fixed gasket is fixed on an upper end part of the spring. The spring return device is designed to arrange on the installation plate of the unclamping plate. When the unclamping rod impacts the main shaft, a great impact force is generated by the unclamping rod to the main shaft. At the same time, the main shaft generates great reacting force to the unclamping cylinder and the installation plate. The unclamping plate and the installation plate move upward to make the impact force on the main shaft unloaded. Thus, a main shaft bearing is not impacted. After the unclamping process is finished, the main shaft is repositioned through the spring. Only the spring return device is adopted in the unclamping device in the utility model. The main shaft unclamping device capable of repositioning has a simple structure. The service lifetime of the main shaft bearing can be prolonged effectively. And the maintenance rate and the maintenance cost of a machine tool can be reduced.
Description
Technical field
The utility model relates to the numerical control machine tool technique field, is a kind of numerical control machining center main shaft that adopts spring reset resetting means of forging a knife specifically.
Background technology
At present, known main shaft tool striking device mainly is made up of knife striking cylinder, forge a knife bar and installing plate.When needs were forged a knife, the bar of forging a knife directly impacted main shaft, but main shaft does not have relief arrangement, and all impact forces are all carried by main shaft bearing, and main shaft bearing is easy to impaired, has increased maintenance cost and man-hour.
Summary of the invention
Be prone to deficiency impaired and can't off-load in order to overcome existing main shaft bearing, the goal of the invention of the utility model is to provide a kind of main shaft resetting means of forging a knife, and to reduce the main shaft load that is hit, prolongs the life-span of main shaft bearing.
For realizing above-mentioned purpose, in the knife striking cylinder of the utility model the bar of forging a knife is housed, the bar of forging a knife is over against the alignment of shafts of main spindle box, and installing plate is fixed on the main spindle box, and installing plate and knife striking cylinder are connected as a single entity, and it is characterized in that: spring reverse motion is housed on the installing plate.
The support bar of said spring reverse motion is fixed on the installing plate, is with spring on the support bar, and setting-up piece is equipped with in the upper end of spring.
The utility model has designed spring reverse motion in the installing plate of knife striking cylinder; When the bar of forging a knife impacted main shaft, the pole pair main shaft of forging a knife produced very big impulsive force, and main shaft produces very big reaction force to knife striking cylinder and installing plate simultaneously; Knife striking cylinder and installing plate move upward; The impulsive force of main shaft can be unloaded, can not impact main shaft bearing, forge a knife to accomplish and pass through spring reset afterwards.
The utility model has compared with prior art only adopted spring reverse motion in the tool striking device, simple in structure, can effectively solve the service life that prolongs main shaft bearing, reduces machine upkeep rate and maintenance cost.
Description of drawings
Fig. 1 is the utility model structural perspective;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the enlarged drawing of the broken section I-I of Fig. 2.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, the bar 5 of forging a knife is housed in the knife striking cylinder 4, the hydraulic system of the bar 5 of forging a knife through lathe drives and moves, and the bar 5 of forging a knife is over against main shaft 6 centers of main spindle box 1, and installing plate 2 is fixed on the main spindle box 1, and installing plate 2 is connected as a single entity with knife striking cylinder 4; The support bar 7 of spring reverse motion 3 is fixed on the main spindle box 1; Be with spring 8 on the support bar 7; The lower end of spring 8 contacts with the upper surface of installing plate 2, and the upper end uses setting-up piece 9 and support bar 7 to be solidified as a whole, and support bar 7 is fixed on the main spindle box 1 through thread connecting mode.
When knife striking cylinder 4 oil-feeds are forged a knife; The bar 5 of forging a knife stretches out with main shaft 6 tops and contacts, and main shaft 6 was forged a knife when pressure increased, and the reaction force of main shaft 6 moves upward installing plate 2 and knife striking cylinder 4; The impulsive force of main shaft 6 can be unloaded through spring reverse motion 3; Can not impact the bearing of main shaft 6, but the action of forging a knife makes installing plate 2 and knife striking cylinder 4 recover initial conditions through spring 8 after accomplishing, the whole process of forging a knife is accomplished.
