Description
Technical field
The present invention relates to shake table, especially a kind of nothing is impacted, and vibration is steady, and noise is little, long service life, vertical circular motion vibration bench easy to maintenance.
Background technology
In the existing production, the shake table that the lost foam casting moulding is used all adopts a plurality of shock electric machines to hang over and implements vibration under the table top, and there are the following problems for this structure:
1. can only carry out X, Y, three direction vibrations of Z, molding sand motion in the horizontal direction has certain orientation, is unfavorable for that molding sand is filled to each position of mould form;
2. the exciting force of many vibrating motors, considerable part is cancelled out each other, and a plurality of vibrating motors are difficult to realize that synchronously exciting force produces cyclically-varying, causes vibration not steady;
3. shock electric machine vibrates with table top, causes that very easily loosening the and structural member of motor snaps or ftractures;
4 maintenance difficult.
Summary of the invention
The objective of the invention is at the used shake table of present lost foam casting moulding, all adopt a plurality of shock electric machines to hang over and implement vibration under the table top, exist the molding sand filling inhomogeneous, vibrate not steadily, the problem that motor is easily loosening and structural member easily snaps, ftractures provides a kind of lost foam casting modeling requirement that satisfies, vibration steadily, do not have and impact, vibrating noise is little, and installation, maintenance is vertical circular motion vibration bench easily.
Vertical circular motion vibration bench of the present invention comprises base, motor, transmission device, flexible clutch, vibrator, vibration table surface, fixed support, air spring and gripping mechanism.Base is provided with column.Column links to each other with vibration table surface by air spring.Motor is installed on the base obliquely.Vibrator is installed on the fixed support of vibration table bottom at a certain angle.Electric machine main shaft links to each other with flexible coupling by transmission device.Flexible coupling is connected with vibrator.
Vibrator can be single eccentric block vibration exciter, two eccentric block vibration exciter and multi-eccentric block exciter.
Transmission device can be belt transmission.
Gripping mechanism can be air clamper.
Flexible clutch and air spring can adopt routine techniques.
The axis of vibrator and the vertical line of vibration table surface are at an angle.This angle is determined according to different function requirements.
When the present invention worked, vibration table surface and top object thereof had produced certain frequency, certain amplitude and the horizontal circumference of certain vibration acceleration and the vibration of vertical direction.Vibration mode, vibration parameters can be realized by change vibrator orientation, the eccentric throw of eccentric block, the weight and the motor speed of eccentric block.
Result of use of the present invention:
1. vertical circular motion vibration bench can finely satisfy the requirement of lost foam casting moulding: vibration acceleration 1-2g, and amplitude 0.2-1.0mm, vibration frequency 30-60 hertz, vibration does not steadily have and impacts.
2. vibrating noise is little, has improved working environment.
3. installation, maintenance is convenient.
Structure be hit little, long service life.
Description of drawings
Fig. 1 is the structural map of vertical circular motion vibration bench of the present invention.
The specific embodiment
The invention will be further described below in conjunction with embodiment shown in the drawings.
As shown in Figure 1, vertical circular motion vibration bench of the present invention comprises base 5, motor 7, transmission device 6, flexible clutch 2, vibrator 1, vibration table surface 3, fixed support 9, air spring 4 and gripping mechanism 8.Base 5 is provided with column.Column links to each other with vibration table surface 3 by air spring 4.Motor 7 is installed on the base 5 obliquely.Vibrator 1 is installed on the fixed support 9 of vibration table 3 bottoms obliquely.Electric machine main shaft links to each other with flexible coupling 2 by transmission device.Flexible coupling 2 is connected with vibrator 1.Vibrator 1 is two eccentric block vibration exciters.Transmission device 6 is a belt transmission.Gripping mechanism 8 can be air clamper.There is a guard shield 10 the shake table outside.
After sandbox is placed on the table top 3, by pneumatic chucking mechanism 8 chuckings.Make air spring 4 inflations, chucking cylinder action card tight sand case by pneumatic control system.Starter motor makes motor reach certain rotating speed by the frequency modulator in the electric-control system, passes through belt pulley, and---belt---belt pulley---flexible clutch drives vibrator 1.Rotate at a high speed with the vibrator eccentric block of the angled α of mesa shape, make vibration table surface 3 and top object thereof produce certain frequency, certain amplitude and the horizontal circumference of certain vibration acceleration and vibration vertically.Vibration mode, vibration parameters can be realized by the eccentric throw, weight and the motor speed that change vibrator orientation, eccentric block.
The frequency modulation speed change of the dynamo-electric machine of pneumatic chucking mechanism is routine techniques.
The axis of the two eccentric block vibration exciters 1 of the present invention and the vertical line of vibration table surface 3 be α at an angle.Established angle α can change at the 0-90 degree.When established angle is 0 when spending, vibrate to be horizontal circular motion, established angle then forms the synthetic of vertical and horizontal circular vibration greater than 0 degree, and increases with established angle, and the vertical vibration component strengthens, and horizontal circumference oscillating component constantly reduces.Established angle reaches 90 when spending, and then forms the horizontal vibration of a vertical vibration and a direction.
The turning cylinder of vibrator 1, and is connected with transmission device 6 and motor 7 by the break-in flexible clutch on support 9 by bearing fixing.Transmission device 6 and motor 7 do not participate in vibration.
In, the small vibration platform adopts a Daepori three-way motor to drive a cover vibrator, vibration is steadily.Can adopt multiple electric motors to drive many cover vibrators for large vibration table and implement vibration, a plurality of rotating speed of motor are consistent as far as possible, and perhaps, a motor drives many cover vibrators by synchronous belt, makes each vibrator synchronization, to obtain stationary vibration.
The eccentric block of vibrator 1 is adjustable.Adjust motor speed by frequency modulator, and then adjust vibration frequency and exciting force.
Can on the display screen of switch board, show vibration parameters at any time at vibration table surface certain position sensor installation.
Vertical circular motion vibration bench of the present invention is driven and the angled vibrator of mesa shape by flexible clutch by fixed common electric machine, makes table top form vertical circular motion, has overcome a series of problems that existence is closed in traditional vibration.
