Abstract
The utility model discloses a slipway dragging device with compensating function, comprising an adjusting plate rotating shaft seat, a rotating shaft, an adjusting plate, a dragging pin, a screw rotating shaft seat, a shaft, an adjusting screw, a rolling screw rod, a nut, a nut seat and a fastening piece. The adjusting plate rotating shaft seat and the screw rotating shaft seat are fixed on the bottom surface of a slipway; the rotating shaft and the shaft are respectively fixed on the adjusting plate rotating shaft seat and the screw rotating shaft seat through set screws; the adjusting plate can rotate around the rotating shaft and the adjusting screw can rotate around the shaft in the free state; the dragging pin is fixed on the adjusting plate, is matched with the nut seat and can move up and down in a pin hole of the nut seat; and the nut is arranged in the rolling screw rod and is fixed on the nut seat. Because the gasket adjustment is replaced by the spiral adjustment, the adjustment is continuous and convenient, and the mounting precision and the mounting efficiency are improved. Because the connection between the nut seat and the slipway is changed into movable connection, and a certain processing error is allowed, and the processing cost is reduced.
Description
Technical field
The utility model relates to the material manufacture field, particularly a kind of slide unit actuator with compensate function.
Background technology
The material process equipment often utilizes ball-screw nut (worm drive) to drive slide unit and realizes moving forward and backward on line slideway, so that slide unit switches between each station.The slide unit bottom is installed slide block and is moved along line slideway, and ball-screw is by the frame support frame, and by the driven by servomotor rotation, feed screw nut is fixed in nut seat, and nut seat is connected with slide unit, and nut drags the slide unit rectilinear motion.Existing slide unit actuator (feed screw nut seat) is fixedlyed connected with being connected to of slide unit, shown in Chinese patent CN200810195920.8.The slide unit that ball-screw drives requires very high to the depth of parallelism of leading screw and slide unit guide rail and leading screw axis.In order to reach the requirement of the above-mentioned depth of parallelism: the measure of taking mainly contains 1) to the strict requirement on machining accuracy of supporting seat stationary plane proposition at feed screw nut seat and leading screw two ends, this certainly will increase processing cost.2) between the supporting seat and its stationary plane between feed screw nut seat and the slide unit bottom surface and leading screw two ends, the shimming adjustment, this adjustment is a phase step type, adjusts both inconveniences, precision is not high yet.
The utility model content
At the problems referred to above, the utility model provides a kind of slide unit actuator with compensate function, replace the pad adjustment with adjustable diameter and screw adjusting, make adjust become continuously, convenient, improve installation accuracy and installation effectiveness, being connected between nut seat and slide unit made into to flexibly connect, in the slide unit moving process, with flexibly connecting the discrepancy in elevation that compensates leading screw axis and the not parallel generation of slide unit guide rail automatically, promptly allow mismachining tolerance to a certain degree to exist, thereby will hang down processing cost.
For achieving the above object, the utility model is by the following technical solutions:
A kind of slide unit actuator with compensate function, it comprises adjusts the plate shaft seat, rotating shaft, adjust plate, drag pin, the screw rod shaft seat, axle, adjust screw rod, rolling lead screw, nut and nut seat and securing member, adjust plate shaft seat and screw rod shaft seat and be fixed in the slide unit bottom surface, rotating shaft and axle are separately fixed at by holding screw and adjust on plate shaft seat and the screw rod shaft seat, adjusting plate under the free state can rotate around the shaft, adjusting screw rod can pivot, dragging pin is fixed on the adjustment plate, and cooperate with nut seat, dragging pin can move up and down in the pin-and-hole of nut seat, rolling lead screw is equipped with nut, and nut is fixed on the nut seat.Adjusting plate is being long lumbar hole with adjusting the screw rod junction, adjusts screw rod and can slide therein.
The operation principle of the slide unit actuator of band compensate function is as follows:
Adjusting plate is being long lumbar hole with adjusting the screw rod junction, adjusting screw rod can slide therein, adjust plate shaft seat, rotating shaft, adjustment plate, screw rod shaft seat, axle and adjust screw rod and constitute typical four-bar mechanism, the angle of plate can be adjusted in the position of adjusting the screw rod top nut, also just adjusted and dragged the angle of pin with respect to the leading screw axis, this adjustment is carried out continuously by nut, can adjust to accurately vertical with the leading screw axis with dragging pin.
In the slide unit moving process, if because of leading screw and guide rail not parallel, make leading screw center line and guide level produce difference in height in former and later two positions, because dragging pin can move up and down in the pin-and-hole of nut seat, and that the length that makes whole actuator adapts to the discrepancy in elevation automatically is required, can not produce leading screw is produced additional bending moment.Therefore played the effect of compensation mismachining tolerance, can make machining accuracy reduce decrease machining cost.
The utlity model has following advantage: easy to adjust, adjust precision and efficiency of assembling height, processing cost is low.

The specific embodiment
As Fig. 1～shown in Figure 3, a kind of slide unit actuator with compensate function, it comprises adjusts plate shaft seat 3, rotating shaft 4, adjust plate 5, drag pin 6, screw rod shaft seat 7, axle 8, adjust screw rod 9, rolling lead screw 10, nut 1, nut seat 2 and securing member, adjust plate shaft seat 3 and screw rod shaft seat 7 and be fixed in the slide unit bottom surface, rotating shaft 4 and axle 8 are separately fixed at by holding screw and adjust on plate shaft seat 3 and the screw rod shaft seat 7, adjust plate 54 rotations around the shaft under the free state, adjusting screw rod 9 can be around axle 8 rotation, dragging pin 6 is fixed on the adjustment plate 5, and cooperate with nut seat 2, dragging pin 6 can move up and down in the pin-and-hole of nut seat 2,10 are equipped with nut 1 on the rolling lead screw, and nut 1 is fixed on the nut seat 2.
Adjusting plate 5 is being long lumbar hole with adjusting screw rod 9 junctions, adjusting screw rod 9 can slide therein, adjust plate shaft seat 3, rotating shaft 4, adjustment plate 5, screw rod shaft seat 7, axle 8 and adjust screw rod 9 and constitute typical four-bar mechanism, the angle of plate 5 can be adjusted in the position of adjusting screw rod 8 top nuts 1, also just adjusted and dragged the angle of pin 6 with respect to the leading screw axis, this adjustment is carried out continuously by nut 1, can adjust to accurately vertical with the leading screw axis with dragging pin 6.
