Abstract

The utility model provides a guiding rod with a rolling ball and counterweight cylinder integrated linkage mechanism for lifting equipment, which mainly comprises a base body, an oil hydraulic system and a control system. A counterweight cylinder of the oil hydraulic system is integrally matched with a guiding rod with a rolling ball of the control system. When the guiding rod with the rolling ball shifts, an oil hydraulic cylinder can instantly conduct synchronous movement with rapid reaction. The guiding rod and the oil hydraulic cylinder are positioned on the same axial line and thus lifting movement is balanced. In addition, the effective moving stroke of the guiding rod and the oil hydraulic cylinder is greatly reduced, an occupied space is small and flexural deformation can be avoided.

Description

The ball guide rod of jacking equipment and counterweight cylinder one interlinked mechanism
The utility model relates to a kind of processing work tool, especially refer to a kind of jacking equipment that drives the lifting of processing headstock, defeated by the ball guide rod with oil pressure counterweight cylinder, processed headstock lifting displacement and control, and do dynamic balancing, be swift in response, and save the ball guide rod and the counterweight cylinder one interlinked mechanism of the jacking equipment in the facility space that takies.
Generally process the facility of operation at relatively large object, because volume, the weight of large-sized object are huge, be difficult in processing is carried out, reach processing purpose by the displacement of control machined object, so mostly be the top to bottom, left and right, front and rear displacement of control processing headstock, so that the machined object that is fixed on board is processed, these facility classes are as planer-type machine-tool, bridge-type stone processing machine etc.
Because the processing headstock of these facility is with processing head, equipment such as CD-ROM drive motor are integrated and are set up in its crossbeam, its overall weight is often up to tens of even up to a hundred kilograms, make this processing head lifting if only rely on the transmission of ball guide rod, then for use diameter and depth of threat certainly will to be selected, the thick extremely thick ball guide rod of tooth could be competent at, this type of ball screw but is difficult to accurate control, and it moves a little, can't carry out the high processing operation of precision requirement, on the other hand, the processing headstock is when lifting, overall weight is all loaded by the ball guide rod, also cause its easy fatigue and service life short, and need to be equipped with power output, the motor beginning that moment of torsion is big can drive the ball screw action, thus, the more related weight that increases the weight of the processing headstock, so, these facility just cooperate the ball guide rod to drive the lifting of processing headstock by oil hydraulic cylinder, utilize oil hydraulic cylinder to support the weight of processing headstock, when the processing headstock is desired the lifting displacement, ordering about its lifting oil hydraulic cylinder with ball screw then cooperates this ball guide rod action lifting to bear the weight of processing headstock, can drive the lifting of processing headstock, this ball screw can be matched diameter and depth of threat, the thick less specification person of tooth, be beneficial to the lifting of accurate control processing headstock, only need jointly with general smaller power, the motor of moment of torsion can drive the action of ball guide rod smoothly, this class cooperates this ball guide rod to bear the oil hydraulic cylinder of main load, owing to can cooperate the weight of supporting the processing headstock, so the logical counterweight cylinder of being called.
Consult Fig. 1, for being equipped on the known jacking equipment of bridge-type stone processing machine crossbeam, it mainly comprises a support 1, one oil hydraulic system 2 and a control system 3, wherein, this support 1 sliding pivot is set up in crossbeam 9, edge is upright establishes four sleeve pipes 101 to this support 1 in abutting, this sleeve pipe 101 pivot respectively is with a pillar 102, these pillar 102 tops, the bottom respectively with two fixed heads, 103 interlockings, for connecing the CD-ROM drive motor 4 of establishing system of processing respectively, processing head 5, this oil hydraulic system 2 is communicated with oil storage tank by some pipelines 202 respectively by two oil hydraulic cylinders 201 and the oil pressure pump (not shown) constitutes, this support 1 is located in these oil hydraulic cylinder 201 location, and lay respectively at this crossbeam 9 both sides, push shaft 203 ends in these oil hydraulic cylinder 201 axle center join with this fixed head 103, for supporting this system of processing, this control system 3 is by two ball guide rods 301, one motor 302 constitutes, this each ball guide rod 301 is adjacent with this each oil hydraulic cylinder 201 respectively, these ball guide rod 301 two ends join with this each fixed head 103 respectively, this each ball guide rod 301 is swivel nut one leader casing 303 respectively, a be coupling belt pulley 304 and pivot of this leader casing 303 inserts in this support 1, this motor 302 passes through a reductor 305 interlocks one belt pulley 306 in addition, this belt pulley 304 is by other belt pulley 306 interlocks of driving belt 307 and this, to drive this ball guide rod 301 axial displacements.
During actual operation, the weight that supports the processing headstock by this oil hydraulic cylinder 201 makes it be positioned desired height, when the processing headstock is desired lifting to be taken in response to processing, this motor 302 is other this belt pulley 304 of belt pulley 306 interlocks by this, these leader casing 303 rotations, impel this ball guide rod 301 axial displacements, when these ball guide rod 301 axial displacements, push away, draw this fixed head 103 of interlock, and then the pressure of these oil hydraulic cylinder 201 inner oil storage space is changed, this equal pressure changes and impels this oil pressure pump action by perceptron, with to these oil hydraulic cylinder 201 delivering oils or impel the fluid in this oil hydraulic cylinder 201 to flow out, make this push shaft 203 along with these ball guide rod 301 actions, to provide support the holding power of processing headstock, to alleviate the load of this ball guide rod 301.
Though aforementioned known jacking equipment can be by the support of this oil hydraulic cylinder 201, alleviate the load of this ball guide rod 301, but, this oil hydraulic cylinder 201 is to borrow these ball guide rod 301 actions to cause its internal pressure to change, this oil pressure pump of Fang Qidong begins action to impel this oil hydraulic cylinder 201, the time point of the two origination action exists some gaps, and this oil hydraulic cylinder 201 is adjacent upright establishing with this ball guide rod 301, cause rising, produce deflection when falling action and be difficult to balance (as shown in Figure 2), and just because this ball guide rod 301 and these oil hydraulic cylinder 201 apart segment distances, when these ball guide rod 301 actions reach certain degree, oil liquid pressure in this oil hydraulic cylinder 201 just changes, can't be according to these ball guide rod 301 immediate responses, make this ball guide rod 301 still need bear suitable load, easily influence the accuracy that it uses service life and action, moreover, effective lifting travel when the effective action stroke of this ball guide rod 301 and this oil hydraulic cylinder 201 is the processing of processing headstock, cause its entire length excessive, on the one hand facility are taken up room greatly, with regard on the other hand, the length of this ball guide rod 301 and this oil hydraulic cylinder 201 is big, also is easy to generate the deflection deformation phenomenon.
