The standard gear 23 is installed in the positioning taper sleeve 16-5 through a standard gear mandrel 16-6 and is pressed and fixed through a screw by the pressing sleeve 16-9. When the standard gear is installed, firstly, the jumping quantity of a lower standard gear mandrel is checked, a mark corresponding to a high-low point (the high point corresponds to the low point, the low point corresponds to the high point) of an upper standard gear is made, then the actual jumping quantity (such as a main sectional view diagram) of the standard gear is detected again after the standard gear is installed, the direction of the high-low point of the standard gear is horizontal (such as a overlooking diagram), and at the moment, the rotating angle of the motor is set to be an initial zero position. When the master gear engages the workpiece, the measurement system begins to acquire the value of the second displacement sensor 16-10, one tooth per revolution, until the workpiece makes one revolution. The standard gear and the installation positioning error thereof are compensated through the following graph, so that a more accurate detection result is obtained. Before the gear to be measured is meshed with the standard gear, the pressure of the second displacement sensor 16-10 and the anvil 16-12 is adjusted, and the pre-pressure is preferably 3/4 of the effective stroke of the sensor. When the standard gear is engaged with the measured tooth, the preload amount is reduced. And the sensor is protected.
Before the invention is used, installation and adjustment are carried out.
First, adjusting ground foot 1
The observation level gauge 26 enables the right side of the whole measuring table to be slightly higher, so that the measured gear is prevented from being driven by the measuring table to mount a workpiece point A from the initial time, and when the measured gear moves to a comprehensive detection point C rapidly, the sensor 16-10 and the measuring anvil 16-12 have larger displacement due to inertia.
Secondly, determining the coordinates of the installation position of the workpiece
The L size, i.e., the mounting position coordinates of the workpiece, is determined with the axis of the master gear 23 as the origin of coordinates. This position is convenient both for the mounting of the workpiece and for the adjustment of the character reading mechanism 8 and the photoelectric switch 8-8.
Thirdly, adjusting the photoelectric switch 8-8
When the workpiece is in the correct position, the switch can be triggered to judge whether the workpiece exists or not.
Adjusting character reader 8-1
When the workpiece is in the correct position, the height of the character reader is adjusted until the reading range is the whole lettering surface.
Fifthly, adjusting M value side head 9-7, photoelectric switch B, first displacement sensor 9-9 and adjusting marking machine 11
And when the measurement sliding table is moved to the point B of the M value measurement position, the position of the photoelectric switch is adjusted to ensure that the photoelectric switch has signal output. The adjustment of the M value side head 9-7 and the first displacement sensor 9-9 is described in an M value side head mechanism, and the marking machine is adjusted by the marking machine lifting platform 12 and the marking machine moving handle 14 to complete the determination of the marking position.
Sixthly, adjusting the second displacement sensor 16-10
The amount of pressure between the second displacement sensor 16-10 and the anvil 16-12 is adjusted and set to zero.
The specific implementation of the whole machine after the installation and debugging is as follows:
firstly, inputting parameters of the standard gear 23 and the measured gear 22 on the touch screen 13: the number of teeth and the modulus (according to this parameter the software can automatically calculate the L2 distance, i.e. the C point coordinate). When the measuring sliding table is positioned at the point A of the workpiece mounting position, a signal can be sent to the manipulator to mount the workpiece in a full-automatic state (semi-automatic manual feeding and discharging). When the gear 22 to be measured is installed in the workpiece positioning sleeve 21 and is detected by the photoelectric switch 8-8, a signal is sent to the character reader 8-1, the character reader 8-1 starts to read characters (information such as product drawing numbers and serial numbers) on the part to be measured, and meanwhile, the aperture value of the gear to be measured is also measured by a sensor built in the positioning sleeve (refer to a schematic diagram of a movable sliding table). All measurement results are sent to the marking machine.
The character reader 8-1 signals a control system after reading is finished, informs the servo motor 6 to rapidly move to a point C meshed with the standard gear 23 (if the character reader has no signal output within n seconds, namely the character is seriously damaged and can not be identified, a mechanical handle is instructed to grab or alarm a part to be detected and carry out manual operation to continue running), and two states are available after the point C is reached: normal engagement and abnormal engagement.
When normally engaged, the amount of compression between the second displacement sensor 16-10 and the anvil 16-12 varies within a small range, and the control system commands the rotation of the servo motor 18 and the synchronous operation of the two vision cameras 20-1 according to the amount of compression. Namely the detection of the measured gear indexing runout and the grinding tooth surface flaw.
When the gear is not normally engaged, the second displacement sensor 16-10 and the measuring anvil 16-12 are disengaged, at this time, the control system commands the servo motor 6 to drive the measuring sliding table to retreat, and commands the servo motor 18 to drive the standard gear 23 to slightly rotate for a certain angle after the retreat is finished. And commanding the servo motor 6 to drive the moving sliding table to the point C at the meshing position of the standard gear 23 again until the normal meshing state is reached and returning to the initial zero position of the servo motor to start measurement.
The standard gear 23 rotates to drive the measured gear 22 to rotate for more than one circle, and the run-out value of the indexing circle can be measured through the compression change of the second displacement sensor 16-10 and the measuring anvil 16-12. When the measured gear 22 rotates for more than one circle and the proximity switches 9-8 are triggered, the control system instructs the servo motor 6 to drive the measurement sliding table to move to the point B of the M value measurement position. After reaching point B, the photoelectric switch B is also triggered to feed air to the two needle cylinders 9-13. The needle cylinder drives an M value side head on the sliding table to measure an M value (a bar span distance) of the gear to be measured through a cylinder push block 9-12 connected with the sliding table 9-1. The measurement result of the M value is that the real M value of a machined part is measured by a universal measuring tool and is used as a standard (a mark is made to be used as a calibration piece). And the M value of the measured gear is obtained by calibrating the M value. Namely, when the calibrating piece and the measured gear are measured, the sum and difference operation after the compression quantity comparison between the first displacement sensor 9-9 and the sensor collision block 9-11 at two positions is carried out.
After the M value is measured, the needle cylinder 25 is cut off, and the two M value side heads retract simultaneously. The two first displacement sensors 9-9 and the sensor collision blocks 9-11 are disengaged simultaneously. The marking machine 11 starts to print and mark the data collected in the whole measuring process according to the requirement of the client.
The human-computer interaction of the whole measuring movement process and the visualization of the measuring result are realized by the touch screen 13 or the display 10 and the industrial personal computer.
It should be understood by those skilled in the art that the above description is only a preferred embodiment of the present invention, and not intended to limit the present invention, and any modification, combination, replacement, improvement made without departing from the spirit and principle of the present invention shall fall within the protection scope of the present invention.
