Abstract
The utility model discloses a counterweight balancing device of a processing center, which comprises a nitrogen tank, a gas pipe and a balancing cylinder. The gas pipe is communicated with a gas outlet of the nitrogen tank and a lower cylinder body of the balancing cylinder, the balancing cylinder is arranged vertically, and a piston rod extends out of the lower cylinder body and is fixed to a spindle. The counterweight balancing device can guarantee load balance when a spindle motor of the processing center moves, the spindle moves up and down stably in a vertical direction without impact, power consumption is less, response speed is fast, accordingly, energy is saved, processing precision is improved, and the counterweight balancing device is easy to be controlled.
Description
Technical field
The utility model relates to the counterweight balancing device that a kind of machining center is used.
Background technology
Along with constantly popularizing of machining center, make extensive Precision Machining be achieved.The vertical machining centre balance weight mechanism mainly still adopts balancing weight to solve the counterweigh problem that main shaft moves vertically at present; Principle is: when the spindle motor driving main shaft moves up and down; Balancing weight is connected with main shaft and drives main shaft through chain and moves up and down; Help overcomes the gravity effect of main shaft, reduces spindle motor and promotes the required power of main shaft, and reduce the quick downslide problem that possibly occur when moving down.Like Chinese patent ZL201020103046.3 disclosed " a kind of device that moves up and down that is used for the machining center balancing weight "; This device comprises column; The top of said column is provided with the guide pillar support near the left end place, and the bottom of guide pillar support is provided with the balancing weight guide pillar, and the bottom of balancing weight guide pillar is connected with said column through the guide pillar lower carriage; The right side of balancing weight guide pillar is provided with balancing weight, is connected through linear bearing between balancing weight and the balancing weight guide pillar.Between balancing weight guide pillar and balancing weight, increase linear bearing; It is more stable that balancing weight is moved up and down at a high speed; But still there is following defective in this mode: 1) the balancing weight volume is big; It is big to move inertia, is easy to generate mechanical shock, vibration and noise when mobile, influences the machining accuracy of lathe easily; 2) counterweight end and mobile terminal exist weight difference to be difficult for regulating; 3) balancing weight is easy to generate double swerve, causes the instability of machining accuracy, is difficult for improving the machining accuracy and the surface quality of product.
The utility model content
The purpose of the utility model is to solve the problem that prior art exists, and the counterweight balancing device that provides a kind of novel machining center to use can be guaranteed the precision of processing, and simple in structure, and it is convenient to implement.
The technical scheme that realizes the utility model purpose is a kind of counterweight balancing device of machining center, comprises nitrogen pot, tracheae and balance cylinder; Said tracheae is communicated with the gas outlet of nitrogen pot and the bottom cylinder body of balance cylinder; Said balance cylinder vertically is provided with, and piston rod stretches out the bottom cylinder body and fixes with main shaft.
Said nitrogen pot is fixed on the side of machining center column through the nitrogen pot support; Said balance cylinder is fixed on the top of machining center column through the cylinder support.
The counterweight balancing device of above-mentioned machining center also comprises the controlling organization of the gas outlet switching of controlling nitrogen pot.
Adopted technique scheme, the utlity model has following beneficial effect: the utility model can guarantee spindle motor balancing the load when mobile of machining center, and main shaft moves down steadily in vertical direction; Do not have and impact; Power consumption is few, and response speed is fast, thereby has saved the energy; Improve machining accuracy, and be easy to control.
Description of drawings
For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing
Fig. 1 is the structural representation of the utility model.
Label in the accompanying drawing is:
Nitrogen pot 1, nitrogen pot support 11, tracheae 2, balance cylinder 3, piston rod 31, machining center column 4, main shaft 5, spindle motor 6, line slideway 7.
The specific embodiment
(embodiment 1)
See Fig. 1, the counterweight balancing device of the machining center of present embodiment comprises the controlling organization that the gas outlet of nitrogen pot 1, tracheae 2, balance cylinder 3 and control nitrogen pot 1 opens and closes.Nitrogen pot 1 is fixed on the side of machining center column 4 through nitrogen pot support 11.Tracheae 2 is communicated with the gas outlet of nitrogen pot 1 and the bottom cylinder body of balance cylinder 3; Balance cylinder 3 vertically is provided with, and is fixed on the top of machining center column 4 through cylinder support 31, and piston rod 31 stretches out bottom cylinder body and fixing with main shaft 5.
During work; Spindle motor 6 on being positioned at main shaft 5 is just changeing when driving main shaft 5 and on line slideway 7, moving up, and controlling organization is opened the gas outlet of nitrogen pot 1, and high pressure nitrogen gets into the bottom cylinder body of balance cylinders 3 through tracheae 2; The piston rod 31 of balance cylinder 3 is moved up; Move thereby drive on the main shaft 5, help spindle motor 6 to overcome the gravity effect of main shaft, reduce spindle motor 6 lifting main shafts 5 required power and export.Otherwise when spindle motor 6 counter-rotatings, when drive main shaft 5 moved down on line slideway 7, the gas of balance cylinder 3 bottom cylinder bodies had been compressed interception, the quick downslide problem that minimizing possibly occur when moving down because of main shaft 5.Defective such as big with regard to the impact of having avoided traditional balancing weight to bring like this, that noise is big has improved the stability and the machining accuracy of lathe.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
