Abstract

The utility model discloses a test machine for inspecting a front drive axle of a tractor. The machine is characterized in that a vibration sensor, a condenser microphone, an oil gun and three oil drip pans are mounted on the top of a test bench; brake devices are respectively installed on the front and the rear sides of the oil drip pans on the left and the right sides; V-shaped blocks are installed on the front and the back sides of the oil drip pan in the middle respectively, and adjustable supports are installed on the left and the right sides of the middle oil drip pan respectively; a rotating shaft of a variable-frequency speed-regulating motor is fixedly connected to a shaft coupling by a bolt; and the shaft coupling is connected to one end of a connecting shaft, the other end of which is sleeved in a spline sleeve. Through the above arrangement, the test machine achieves comprehensive inspection testing of a front drive axle of a large or medium power tractor. Semi-automatic operations needing only one worker are achieved; the test period is shortened; the labor intensity of workers is reduced; the production efficiency is improved; and various test data of the drive axle in an operating state are reflected truthfully.

Description

A kind of tractor drive front axle test experience machine

Technical field

The utility model relates to a kind of experiment machine that detects use, is a kind of machine that detects simulation test before dispatching from the factory for big-and-middle horsepower tractor drive front axle specifically.

Background technology

The tractor drive front axle assembly steering of big-and-middle horsepower on domestic market, in the testing process before dispatching from the factory, the method for employing is single, needs many people's operations, has the shortcomings such as automaticity is very low, detection efficiency slow, project detection is single.

Summary of the invention

The purpose of this utility model is that a kind of detection simulation test machine addressing the above problem is provided.

To achieve these goals, the utility model is installed respectively vibration transducer, condenser microphone, filling gun and three oil drain pans at the table top of experiment table, wherein clamping device is installed respectively in the both sides, front and back of the oil drain pan of the left and right sides, V-block and adjustable supports are installed respectively in the front and back of the oil drain pan in centre position and the left and right sides, frequency-conversion and speed-regulation motor is arranged on the table top of experiment table, the rotating shaft of frequency-conversion and speed-regulation motor is fixed together by bolt and shaft coupling, shaft coupling connects with one end of coupling spindle, and the other end of coupling spindle is enclosed within spline housing.

By above setting, the utility model has been realized the function that big-and-middle horsepower tractor drive front axle is carried out to comprehensive detection experiment, integrate multinomial test item, vibration transducer, condenser microphone and frequency-conversion and speed-regulation motor are connected with computer, can realize the semi-automatic movingization operation that only needs a people, shorten the test period, reduce labor strength, improve production efficiency, reacted more truly Tractor Driving Axle various test figures under operating condition.

Accompanying drawing explanation

Now by reference to the accompanying drawings the utility model is described further.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the working state schematic representation that the utility model detects simulation test tractor drive front axle.

In figure: 1, experiment table, 2, vibration transducer, 3, condenser microphone, 4, filling gun, 5, oil drain pan, 6, clamping device, 7, V-block, 8, adjustable supports, 9, frequency-conversion and speed-regulation motor, 10, shaft coupling, 11, coupling spindle, 12, spline housing.

Embodiment

As Fig. 1, shown in 2, the utility model is installed respectively vibration transducer 2 at the table top of experiment table 1, condenser microphone 3, filling gun 4 and three oil drain pans 5, wherein clamping device 6 is installed respectively in the both sides, front and back of the oil drain pan 5 of the left and right sides, V-block 7 and adjustable supports 8 are installed respectively in the front and back of the oil drain pan 5 in centre position and the left and right sides, frequency-conversion and speed-regulation motor 9 is arranged on the table top of experiment table 1, the rotating shaft of frequency-conversion and speed-regulation motor 9 is fixed together by bolt and shaft coupling 10, shaft coupling 10 connects with one end of coupling spindle 11, the other end of coupling spindle 11 is enclosed within spline housing 12.

By above setting, vibration transducer 2, condenser microphone 3, clamping device 6 and frequency-conversion and speed-regulation motor 9 are connected with computer by wire, tractor drive front axle is placed on two adjustable supports 8 and V-block 7 fixing, because tractor drive front axle itself is very heavy, therefore without compression, frequency-conversion and speed-regulation motor 9 is connected with the spline bevel gear shaft of tractor drive front axle with spline housing 12 by shaft coupling 10, spline housing 12 slides on coupling spindle 11, can make spline housing 12 engage or depart from the spline bevel gear shaft of tractor drive front axle, conveniently assemble and disassemble tractor drive front axle, and by the distance that regulates spline housing 12 to slide on coupling spindle 11, better meet the tractor drive front axle that handling vary in size.

Frequency-conversion and speed-regulation motor 9 is connected with computer by wire, by the multistep speed regulation of Keyboard Control frequency-conversion and speed-regulation motor 9, and positive and negative rotation, and then realize the different rotating speeds of tractor drive front axle under forward and rollover states, react more really the operational situation of tractor drive front axle under complex working condition.

The clamping device 6 of testing table 1 left and right sides is connected with computer, in the time detecting the differential of left and right two wheel hubs, the clamping device 6 of the left and right sides is braked respectively left and right wheel hub by computer control, the rotating speed of left and right wheel hub is imported in computer and is processed by photoelectric encoder, export by display, can directly judge that tractor drive front axle the right and left differential is whether in scope of design.

Vibration transducer 2 is connected with computer with condenser microphone 3, and the data that vibration transducer 2 and condenser microphone 3 are detected are processed, and judges that whether product is qualified, then outputs on display.
