Abstract
The utility model discloses a multifunctional mechanical hydraulic balance device which comprises a hydraulic cylinder, a connecting bracket and a hydraulic loop, wherein the connecting bracket is connected with the end of a piston rod of the hydraulic cylinder and is connected with a plurality of moving parts to be balanced to balance the dead weight of the moving parts, and the hydraulic loop is connected with the hydraulic cylinder to control the forward movement and the backward movement of the piston rod. The cost of the device is low, the machining requirement of the device is low, and the economic benefit is higher.
Description
Technical field
The utility model relates to a kind of multi-function mechanical-hydraulic bascule, specifically relates to a kind of multi-function hydraulic balance device that is applied to machining tool toolbox and crossbeam, main spindle box, ram, lifting industry etc.
Background technology
Bascule is to be used for device that knife rest etc. needs balance carrying out the major part of balance, and traditional balanced controls mainly are the counter weight type balanced controls that the design feature according to the balance object is provided with, and are simple in structure, but the dynamic equilibrium effect is bad.
Because existing balanced controls are installed in above the body of plant equipment, have strengthened the whole height of plant equipment, have reduced the kinetic stability and the dynamic response that are balanced moving component.
Because the counterweight dynamic stability of existing balanced controls is poor, be difficult to keep the constancy of the dynamic application of force, and then very difficult assurance needs the stationarity of workpiece in motion process of balance again.
When moving component was done the bottom and top feed motion under ball-screw drags, existing bascule can't play the effect of balance exercise parts deadweight.The power that leading screw bears is bigger, and it is steadily poor comparatively speaking to move, the service life of having reduced leading screw.
Summary of the invention
Therefore, the utility model is poor at the counterbalance effect of existing counter weight type balanced controls, and especially the defective of dynamic effect difference provides a kind of cost low, low to processing request, and the higher multi-function mechanical-hydraulic bascule of economic benefit.
The technical solution adopted in the utility model is:
The multi-function mechanical-hydraulic bascule of the utility model, comprise hydraulic cylinder, be connected this hydraulic cylinder the piston rod end be used to be connected on the movable part of ready to balance connection support with the deadweight of balance exercise parts, and be connected on the described hydraulic cylinder hydraulic circuit with the positive and negative motion of control piston bar.
Multi-function mechanical-hydraulic bascule according to technical solutions of the utility model can be provided with in the both sides of moving component under user mode, when moving component such as doing bottom and top feed when motion under the dragging of ball-screw, oil cylinder can play the effect of balance exercise parts.This balance mode is few than the factor of the existing required consideration of balanced controls, and cost can significantly reduce.And its balance exercise parts realize by supporting, and are lower to the requirement of processing, thereby, improved the economic benefit of this mechanical-hydraulic bascule on the whole.
Above-mentioned multi-function mechanical-hydraulic bascule, described hydraulic circuit is provided with overflow valve.
Above-mentioned multi-function mechanical-hydraulic bascule, the valve of the positive and negative motion of control piston bar of described hydraulic circuit is a magnetic valve, this magnetic valve is synchronous with the control assembly of controlled motion component movement under user mode.
Above-mentioned multi-function mechanical-hydraulic bascule, described connection support is installed on the described piston rod by the packing ring of nut and configuration.
Above-mentioned multi-function mechanical-hydraulic bascule, described connection support is provided with the counterbore corresponding to described packing ring.
Above-mentioned multi-function mechanical-hydraulic bascule, described packing ring comprise spheric washer and the taper faced washer that pairing is used.
Above-mentioned multi-function mechanical-hydraulic bascule, described packing ring branch occupy and connect each the one group of setting of support both sides.
Description of drawings
Below in conjunction with Figure of description in detail the technical solution of the utility model is described in detail, wherein:
Fig. 1 is the structural representation according to a kind of multi-function mechanical-hydraulic bascule of technical solutions of the utility model.
Among the figure: 1, nut, 2, connect support, 3, spheric washer, 4, taper faced washer, 5, piston rod, 6, ring flange, 7, cylinder body, 8, oil pipe, 9, ring flange.
The specific embodiment
With reference to explanation accompanying drawing 1, it shows a kind of multi-function mechanical-hydraulic bascule, comprise hydraulic cylinder, be connected this hydraulic cylinder piston rod 5 ends be used to be connected on the movable part of ready to balance connection support 2 with the deadweight of balance exercise parts, and be connected on the described hydraulic cylinder hydraulic circuit with the positive and negative motion of control piston bar.
Multi-function hydraulic balance device adopts the mode of piston and piston rod static pressure supporting movement parts, its course of work is exactly: the endoporus that inner chamber of cylinder block piston and piston rod pass fairlead and upper cylinder cover stretches out cylinder body, descending on the cylinder cap and other end oil-in and oil-out, design has oil distributing ring and oil outlet on the fairlead, be provided with the balancing cylinder device in the both sides of moving component, when moving component was done the bottom and top feed motion under ball-screw drags, balancing cylinder played the effect of balance exercise parts deadweight.
Because the operating steadily of hydraulic system, therefore, in addition the both forward and reverse directions motion of the moving component of balance steadily, reaction is fast.And adopt hydraulic drive and piston place static pressure support concept, can obtain very large operational forces or work distance.And hydraulic cylinder not and miscellaneous part form friction pair, have anti-leak friction free function, thereby alleviate the power that leading screw bears, prolong leading screw service life.In addition, its low cost of manufacture, the economic benefit height, the operation maintenance is also more convenient.
In order to keep the pressure of hydro-cushion oil cylinder, constant pressure, described hydraulic circuit is provided with overflow valve, need to guarantee the stability of workpiece in motion process of balance.
Dynamic response requirement in view of moving component, the valve of the positive and negative motion of control piston bar of described hydraulic circuit is a magnetic valve, this magnetic valve is synchronous with the control assembly of controlled motion component movement under user mode, synchronously be to realize very easily in Electromagnetic Control, input moment of control signal finishes, and is also very accurate so as to the dynamic stability that realizes.
In order to improve the reliability of connection, described connection support is installed on the described piston rod by the packing ring of nut 1 and configuration.
Further, described connection support is provided with the counterbore corresponding to described packing ring, reduces the negative effect of vibration to connecting.
Preferably, described packing ring comprises spheric washer 3 and the taper faced washer 4 that pairing is used, to obtain better to connect effect.
Preferably, described packing ring branch occupy and connects each the one group of setting of support both sides.
