Abstract

The invention discloses a device for quickly centering and clamping motors during test and provides a device which can quickly replace tested motors and ensure that newly mounted motors are not required to be re-centered. The device comprises a centering box, a torque sensor seat and a flange plate. During machining, by taking a bottom surface of a box as a reference, two holes which are machined at one time in two sides of the box are parallel to the bottom surface and perpendicular to a plane on which motors are arranged, so that the error accuracy is less than 0.03mm during centering and mounting; the torque sensor seat is fixed with the box to form a whole and coaxial with motor mounting holes after being mounted; and when the motors are replaced, the newly mounted motors are not required to be re-adjusted.

Description

A kind of electromechanical testing quick centring clamp device

Affiliated technical field

The present invention relates to describedly according to claim 1, relate to a kind of quick centring for the engine bench test motor clamp device is installed.

Background technology

When traditional streamline rolled off the production line the engine bench test of motor, motor centering need to comprise the centering instrument of complex and expensive and take human resources, and takies a large amount of time.If need simultaneously to measure a plurality of motors, just need to use a plurality of stand operation repetitives, to waste time and energy, and can not guarantee the degree of accuracy of centering, the mistake probability is larger.

Summary of the invention

In order to overcome above deficiency, after only need processing installation, this electromechanical testing quick centring clamp device need not long-time centering, can realize the installation of many motors quick-detachment, required time reduce to be installed as much as possible and to be guaranteed the degree of accuracy of centering, and can avoid the detection mistake that caused by the centering out of true.Simultaneously, this apparatus structure is simple, can greatly reduce cost.

Embodiment

The present invention is mainly by the centering casing, ring flange, and torque sensor seat three parts form.

Ring flange; Mainly by the dish-type base, register pin, bearing, transmission shaft, motor positioning disk five parts form.Such as Fig. 1 (1), during the processing ring flange, take tank floor as thick benchmark, the outstanding and at right angle setting motor plane of a tubulose is done in parallel bottom surface.This position is used for the Primary Location of motor and makes things convenient for subsequent installation to be the dish-type base.The tubular protrusion position in the place ahead is that pre-installation during for the docking of ring flange and casing is prepared on the base, makes ring flange can be suspended on casing when not tightening the screw temporarily and saves manpower, provides simultaneously a rough centering to connect benchmark.Such as Fig. 1 (2), 4 screw holes are for being connected and fixed with the centering casing, after finishing for the ring flange centering of specific motor, being fixed on the centering casing.As be that motor of the same type is changed, then this ring flange need not dismounting, only needs to change motor and can realize high precision, and centering is installed fast.Two register pins that object is motor of Fig. 1 (3) add man-hour according to the demand variable-size of motor.In order to make the errorless Fast Installation of motor installation direction, the size of two register pins is not identical.Show that such as Fig. 2 (3) pin is positioned between motor and Fig. 1 (6) the motor positioning disk, the position can change with different motors.Present motor be on the turning axle symmetria bilateralis position each one, diameter is respectively 64mm and 8mm.Area, can be used for fixing with casing such as (2) four fixed orifices of Fig. 2 greater than centering casing mounting hole less than the area of centering casing installed surface, is used for the motor location such as (1) two pin of Fig. 2.The pin size is respectively 64mm and 8mm, and size can change according to different motors.Fig. 1 (4) and (5) are respectively bearing and transmission shaft, are pressed into the dish-type base during installation, such as need different motors are installed, can be according to the concrete size of new motor, and again processing.Fig. 2 (1) and (2) have shown bearing and the transmission shaft after being pressed into the dish-type base.Actual effect after ring flange and motor are fixed as one as shown in Figure 3.Each ring flange need not dismounting after for the first time centering installs and fixes with the centering casing, unique what need dismounting and change is test or load motor.Because the centering between the transmission shaft has been realized and any change do not occurred when changing motor, also just need not again to carry out centering after next motor is installed on the ring flange, can directly debug and test.And only needing to tighten motor fixing screw behind the alignment finger position when motor is installed can compress, and this has just realized quick centring and clamping synchronously.

The centering casing; Such as Fig. 4 (1), be generally the hollow metal object of a rectangular parallelepiped, the installed surface in the casing both sides perpendicular to ring flange is installed through hole and four pairs of screw mounting holes by machine work by two of the disposable processing of boring machine.Owing to be to carry out one processing by boring machine, can guarantee the precision of 0.03mm.When the ring flange of installation diagram 4 (3), can guarantee the transmission shaft error of centralization less than 0.03mm like this, and reduce the time consumption of centering.During installation, torque sensor base and the casing of Fig. 5 (2) is fixed in a plane, adjusts the torque sensor base, two round ends of torque sensor and the turning axle of load and testing of electric motors are on the position of centering.Then by (1) two connector of Fig. 5 with load motor, torque sensor, testing of electric motors connects as one.Like this after installation, torque sensor and two motor coaxles, and when changing motor, need not that torque sensor is done any adjustment and can realize centering.And can for the ease of changing torque sensor or attractive in appearance, with the tank surface hollow out, make torque sensor more directly perceived.Mounting means as shown in Figure 4, Fig. 6 is the design sketch after integral installation is finished.

The torque sensor seat; Such as Fig. 4 (2), be fixed on the pedestal on the casing, be used for the mounting torque sensor.Carry out centering when installing for the first time and adjust, adjust after finishing coaxially with the motor mounting hole, and do not need to make any change during the installation of motor afterwards.

Carry out because the design mainly is the quick centring for the flange motor, do not carry out explanatory notes so there is any synoptic diagram that the centering of horizontal machine is installed.If any one motor is horizontal, then with the motor front panel angle bar plate of benchmark processing is set.This angle bar plate and ring flange mate, and design ring flange again and cooperate with casing.The base plate of can harmonizing when mounted according to demand cooperates with the motor bottom surface, and for guaranteeing motor shaft to level, angle bar plate requirement on machining accuracy is in 0.03mm; Need on the angle bar plate to be combined with motor and ring flange perpendicular to the punching of motor installed surface and design adapter sleeve, perhaps motor directly passes the angle bar plate and directly is connected with transmission shaft on the ring flange, according to different motor specific designs.
