Description

A kind of synchronization lifting mechanism for measuring machinery
Technical field:
This utility model relates generally to a kind of synchronization lifting mechanism for measuring machinery.
Background technology:
In the structure of machinery measured by part X-ray measuring machine etc., need the overall dimensions according to measured piece, head will be measured solid It is scheduled on moving beam, controls moving beam by elevating mechanism and lift and in position position, by being fixed on mobile horizontal stroke Device on beam adjusts and controls to measure that head rotates, the mode such as flexible detects.During device fabrication, installation and debugging, Equipment uses, in running and require easy and simple to handle in maintenance and repair servicing operations, simultaneously should be time saving and energy saving, low cost, Efficiency is high.
During equipment runs and uses, the control to moving beam lifting is requisite, and requires running During steadily reliable, it is simple to operate and control, owing to the own wt of moving beam is relatively big, especially for the survey of large-scale workpiece Amount device deadweight can be bigger, in moving beam lifting process, requires running stability, the stress equalization of whole equipment relatively Height, rate of occurrence of equipment failure should be low simultaneously, it is simple to safeguards.
Prior art:
A) existing mechanism is typically with one group of screw mandrel and adds one group of line slideway, it is achieved the lifting of moving beam and location. Motor is connected with screw mandrel in the outside of whole device layout, the screw mandrel in this structure and the equal discontinuity equalization of guide rail, makes for a long time Strengthen, with abrasion, the equipment that affects to run.
B) or two groups of screw mandrels add two groups of line slideways, two motors independent control it is connected respectively with screw mandrel in equipment both sides The mode of system, it is achieved the lifting of moving beam and location, this kind of scheme solves the problem of moving beam discontinuity equalization, just Function it is capable of in the case of Chang, but under cover risk, electric fault once occurs, a motor is out of control, can cause two groups of silks Bar runs asynchronous, causes stuck, serious wear or device damage, additionally, the program adds one group of motor reducer and control System processed, the manufacture of equipment, operation and maintenance cost increase, Technical Economy is the highest, does not meets the requirement of energy efficiency.
Utility model content:
This utility model purpose is contemplated to make up the defect of prior art, solution be discontinuity equalization and run not The problem synchronized, it is provided that a kind of synchronization lifting mechanism for measuring machinery, it is simple to safeguard.
This utility model is achieved through the following technical solutions:
A kind of synchronization lifting mechanism for measuring machinery, it is characterised in that: include the frame of frame-type, frame top Fixed cross beam in the middle of motor is installed, motor by being connected with the left and right transverse axis of synchronous axial system on reducer output shaft, The outer end of left and right transverse axis fixed cover respectively is equipped with transverse axis bevel gear;It is fixed with left and right guide rail on frame left and right pillar, left and right leads On rail, slip cap is equipped with moving beam;The two ends of moving beam are provided with feed screw nut, are installed with left and right screw mandrel respectively, left and right The top of screw mandrel fixed cover respectively equipped with the contrary screw mandrel bevel gear of installation direction, described screw mandrel bevel gear respectively with corresponding horizontal stroke Shaft bevel gears engaged transmission.
A kind of synchronization lifting mechanism for measuring machinery, it is characterised in that: it is provided with outside described motor with its transmission even The decelerator connect, the output shaft two ends of decelerator are connected with left and right cross shaft driving respectively.
This utility model is symmetrical layout, has two groups of screw mandrels and two groups of line slideways, solves moving beam liter Stress equalization problem during fall.
The positive and negative installation of this utility model ingenious utilization bevel gear set, by the rotation of two screw mandrels of a driven by motor, Achieving the lifting to moving beam and the synchronicity of location control, simplify the basic structure of product, economical and practical, cost is not Height, can improve the operation stability of product after improvement, reduce equipment attrition, improves and installs the work efficiency safeguarded.
A motor in this utility model is installed on the centre position of a whole set of instrument, while optimizing force structure, makes Uniform force in moving beam lifting process, reduces number of motors, decreases control process, reduces fault rate, fall Low cost.
The utility model has the advantages that:
This utility model is simple and reliable for structure, has strong adaptability, uses the features such as simple, convenient, efficient, low cost, Convenient for installation and maintenance, the stress equalization of mobile measurement, synchronization lifting can well be realized, greatly improve stable equipment operation Property and reliability, be a kind of ideal synchronization lifting mechanism.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is this utility model internal structure schematic diagram.
Detailed description of the invention:
See accompanying drawing.
A kind of synchronization lifting mechanism for measuring machinery, includes the frame 10 of frame-type, the fixing horizontal stroke of frame top Being provided with motor 4 in the middle of beam, the output shaft of motor 4 is connected with left and right transverse axis 3, the outer end of described left and right transverse axis is respectively Fixed cover is equipped with transverse axis bevel gear 2;Being fixed with left and right guide rail 7 on frame left and right pillar, on left and right guide rail 7, slip cap is equipped with shifting Dynamic crossbeam 8;The two ends of moving beam 8 are provided with feed screw nut, are installed with left and right screw mandrel 9,6, the top of left and right screw mandrel 9,6 respectively Portion's respectively fixed cover is equipped with the contrary screw mandrel bevel gear 1,5 of installation direction, and described screw mandrel bevel gear is bored with corresponding transverse axis respectively Meshed transmission gear.
Being provided with the decelerator being in transmission connection with it outside motor, the output shaft two ends of decelerator pass with left and right transverse axis respectively It is dynamically connected.
The power source of elevating mechanism is motor 4 and reductor, and power is delivered to the transverse axis of the left and right sides by two groups of transverse axis 3 At bevel gear 2, two groups of transverse axis bevel gears 2 engage change power transmission with screw mandrel bevel gear (anti-dress) 1 and screw mandrel bevel gear (formal dress) 5 Direction, drive screw mandrel 6 and screw mandrel 9 synchronous axial system, thus promote the lifting of moving beam.The guiding of moving beam lifting is by a left side Right two groups of symmetrical line slideways 7 realize, and the power of moving beam is realized by screw mandrel 6 and the screw mandrel 9 of symmetrical distribution, Such layout ensure that beam force equalizes, it is possible to moving up and down of steady and smooth, uses a driven by motor two groups simultaneously Screw mandrel realizes the lifting of moving beam, it is ensured that synchronicity, contributes to the operation that device systems is reliable and stable.
