Abstract
The utility model relates to a machine tool main spindle head automatic balancing mechanism, which comprises an air storage tank (1) and a balancing cylinder (2), wherein, the balancing cylinder (2) is vertically arranged and is divided by a piston (21) into an upper cylinder body and a lower cylinder body, and the piston (21) is provided with a piston rod (22) which is connected with a main spindle head (3), and the air storage tank (1) is communicated with the lower cylinder body of the balancing cylinder (2), and a priority reducing valve (4) and a pressure regulating valve (5) are arranged between the air storage tank (1) and the balancing cylinder (2). The automatic balancing mechanism has high balancing precision, small volume, low energy consumption and low maintenance cost, and can easily reach 120 m/min after being applied to a numeric-control device, and is stable to run, and is the development trend for the balancing way of the processing center in the future.
Description
Technical field
The utility model belongs to lathe headstock balance field, particularly relates to a kind of lathe headstock balanced controls.
Background technology
Work in-process in the heart, the balance mode of main spindle box is varied, amplifies balance, counterweight balance, oil pressure balance etc. such as servomotor, but various balance modes all have the pluses and minuses of oneself, servomotor amplifies the balance screw rod and strengthens, and nut strengthens, and the speed of service is very fast; But temperature rise is fast and high, and power consumption is big, the maintenance cost height; The counterweight balance cost is low, but speed is slow and unstable; Oil pressure counterweight speed is medium, the reaction be not quick enough and precision not high.The quality of balance is to the machine tool capability important influence, and existing multiple balance mode to lathe generally speaking, all can't reach optimum state, makes machine tool capability can not get maximum performance, influenced machining accuracy and usefulness.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of lathe headstock autobalance, to improve the effect of balance, promotes the machining accuracy and the usefulness of vertical machining centre.
A kind of lathe headstock autobalance, comprise air accumulator (1) and compensating cylinder (2), described compensating cylinder (2) is vertically placed, be separated into upper and lower two cylinder bodies by piston (21), the piston rod (22) that is equipped with on the described piston (21) links to each other with main spindle box (3), air accumulator (1) is communicated with the lower cylinder body of compensating cylinder (2), and constant pressure pressure-reducing valve (4) and pressure regulator valve (5) are housed between air accumulator (1) and the compensating cylinder (2).
Described air accumulator (1) and pneumatic booster body (6) are communicated with.
Beneficial effect
The utility model balance quality height, and volume is little, low power consuming, maintenance cost are low, is applied on the numerical control device, can reach 120m/min easily, and motion stabilization is the developing direction of following machining center balance mode simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 1, a kind of lathe headstock autobalance, comprise air accumulator 1 and compensating cylinder 2, described compensating cylinder 2 is vertically placed, be separated into upper and lower two cylinder bodies by piston 21, the piston rod 22 that is equipped with on the described piston 21 links to each other with main spindle box 3, and air accumulator 1 is communicated with the lower cylinder body of compensating cylinder 2, constant pressure pressure-reducing valve 4 and pressure regulator valve 5 are housed between air accumulator 1 and the compensating cylinder 2, and described air accumulator 1 and pneumatic booster body 6 are communicated with.
After source of the gas enters pneumatic booster body 6, give air accumulator 1 supercharging, the pressure weighing apparatus of final air accumulator 1 fixes on a fixed numeric values.In balanced controls, the lower cylinder body that air accumulator 1 balances cylinder 2 feeds Compressed Gas, gives the thrust that steam-cylinder piston 21 makes progress, and makes the active force of 22 pairs of main spindle boxes 3 of piston rod consistent with the gravity of main spindle box 3.When moving on the main spindle box 3, air accumulator 1 to the quick air feed of lower cylinder body, guarantees that main spindle box 3 still is in poised state by pressure regulator valve 5; When main spindle box 3 moved down, for guaranteeing main spindle box 3 stress balances, level pressure subtracted 4 and presses the automatic earial drainage of valve, guarantees that compensating cylinder internal pressure weighing apparatus is fixed.
Claims (2)
1. lathe headstock autobalance, it is characterized in that: comprise air accumulator (1) and compensating cylinder (2), described compensating cylinder (2) is vertically placed, be separated into upper and lower two cylinder bodies by piston (21), the piston rod (22) that is equipped with on the described piston (21) links to each other with main spindle box (3), air accumulator (1) is communicated with the lower cylinder body of compensating cylinder (2), and constant pressure pressure-reducing valve (4) and pressure regulator valve (5) are housed between air accumulator (1) and the compensating cylinder (2).
