Each system as described above will be described in detail with reference to the accompanying drawings for each system configuration as follows.

First, referring to the valve body drive system 10, the attached figure 4 is a front view showing the overall configuration of the valve body drive system 10, the oil storage tank 11 in the upper portion of the main body 101 is 4 A driving motor 13 supported by two posts 12 and fixedly installed at a predetermined height, and fixedly supported at the bottom plate of the main body 101 while being connected to a separate power source at the bottom thereof, the driving motor 13 of which The oil pump 14 which is operated by the electric motor through the drive side and the coupling, suctions and pressurizes the oil in the oil storage tank 11, and the oil pressure control of the role which keeps oil pressure constant by preventing excessive pressure rise in a hydraulic circuit. A hydraulic block equipped with a valve 15, a hydraulic system 16 indicating the same, a plurality of connectors 18 for binding the oil tube 17, and a solenoid valve 19 for regulating opening and closing of the oil passage therein. (20A) Respectively, it is provided.

Here, the front and both side portions of the oil storage tank 11, respectively, the oil level checker 21 and the oil supply and recovery oil tube 17 for displaying the level of the oil amount filled therein is bound The connector 18 is mounted, and the upper surface portion is provided with two oil circulation pipes 22 for receiving the oil used in the valve body mounting system 30 again.

This oil storage tank 11 is shown in detail in FIG. That is, the oil circulation pipe 22 is connected to each of the two holes (11-11A) formed on both sides of the upper portion of the oil storage tank 11 and at the same time the oil supply and recovery oil tubes (17A and 17C) The float switch 11-2, which is connected to the respective holes 11-1B formed on both side portions of the oil storage tank 11, is an oil shortage warning device inside the oil storage tank 11; One side of the oil storage tank 11 is mounted, and the heater 11-3 as the oil heating means is mounted so that the heat transfer coil, which is the heat transfer medium, is positioned inside. Reference numeral 11-4 denotes a drain hole of the oil storage tank 11.

Under such a configuration, the oil tube 17A connected from the oil supply connector 18 of the oil storage tank 11 is connected to the oil inlet of the oil pump 14 (for example, the oil tube 17A at this time is Larger diameter than other oil tubes 17B to 17F). The oil tube 17B from the oil outlet of the oil pump 14 is connected to one end connector 18 of the hydraulic block 20A, which is a kind of distributor, and from each connector 18 of the hydraulic block 20A. The extending oil tubes 17C, 17D, 17E, and 17F have hydraulic circuits connected to the oil return connector 18 of the oil storage tank 11 and the hydraulic block 20B of the valve body mounting system 30, respectively. Will be done.

Therefore, when the oil pump 14 is operated in accordance with the driving of the drive motor 13, oil introduced into the oil passage inside the hydraulic block 20A is controlled by the oil pressure control valve 15 to the oil tube 17C. The hydraulic block 20B of the valve body mounting system 30 through the oil tubes 17D, 17E, and 17F, which are respectively connected to the three connectors 18 at the same time, is made to be recovered to the oil storage tank 11 through. ) Will be supplied.

The process of switching the flow of oil and intermittent supply of oil in the hydraulic block 20A is performed by the control of the solenoid valve 19 mounted on the upper surface of the hydraulic block 20A. The operation of the oil pump 14, that is, is made in conjunction with the drive of the drive motor 13.

In particular, as shown in Figure 6, the oil storage tank 11 is provided with a heater (11-3) using an oil heating means, for example, a heating coil, the valve body tester 100 of the present invention It is possible to maintain a temperature of 70 ° C to 80 ° C to obtain an approximate result to the actual vehicle. In addition, the heater is operated under the control of the equipment control system 80, the operating state is displayed in the ON / OFF state through the monitor 81 which is one of the test value output means, the drive motor 13 When the normal rotation is controlled to maintain the set temperature and at the same time select the stop of the drive motor 13 through the additional function is controlled to 20 ℃ lower than the set temperature.

Referring to the operation of the valve body drive system 10 configured as described above, since the oil storage tank 11 must first be filled with oil, the oil level checker 21 mounted on the front part of the oil storage tank 11 is described. Fill oil up to the top. Here, such oil levels should be checked from time to time. For example, when the oil is insufficient in the oil storage tank 11, air may be sucked into the oil pump 14 and various hydraulic circuits, which may cause a fatal failure, so that the valve body tester 100 of the present invention may have a float switch 11-2. Even if the oil level is insufficient while the equipment is running, the operation is stopped and a warning message is displayed to the user, but before starting the operation, always check whether the oil is up to the top of the oil level checker 21. Make sure the oil does not drop below half the oil level checker (21).

In addition, the oil filled in the oil storage tank 11 is heated until the temperature of 70 ° C ~ 80 ° C is maintained by the heater 11-3 therein, the oil in a state where the appropriate temperature is reached As the drive motor 13 is rotated, the oil is sucked by the oil pump 14 through the oil tube 17A and pumped to the oil block 20A communicating therewith. At this time, the oil pump 14 is to be rotated in a predetermined direction, and when the re-installation of the power line and repair of the entire power line of the workplace must be adjusted to the rotation direction again.

In addition, the oil pumped from the oil pump 14 to the hydraulic block 20A through the oil tube 17B is a solenoid for controlling the opening and closing of the oil passage through various oil passages formed in the hydraulic block 20A. The valve body is mounted via an oil tube 17, in particular three oil tubes 17D, 17E, 17F, which is sent to each connector 18 and connected to each connector 18 by the operation of the valve 19. It is sent to the hydraulic block 20B of the system 30. At this time, when the pressure in the hydraulic block 20A, that is, the hydraulic circuit is excessively increased, the hydraulic control valve 15 installed in the oil passage between the oil pump 14 and the hydraulic block 20A on the hydraulic block 20A is opened. Since part of the oil is returned to the oil storage tank 11 through the oil tube 17C, the oil pressure in the hydraulic circuit is always kept constant.

Next, with reference to the valve body mounting system 30, the accompanying drawings, Figure 1 is a front view showing the overall configuration of the valve body tester 100, in particular, shows a detailed configuration of the valve body mounting system 30.

The valve body mounting system 30 is composed of up, down conveying means, up and down conveying guide means and valve body fixing means, and hydraulic supply means, wherein the up and down conveying means is the base ( 102 is provided with an integrated upper support plate 32 and a lower support plate 33 which are supported while maintaining a predetermined interval up and down through the four columns 31 at the top, and the bottom of the lower support plate 33 is impacted and While the vibration damping member 34 is inserted and installed, a hydraulic cylinder 35 is vertically installed at the center of the upper surface of the upper support plate 32. The hydraulic cylinder 35 has a cylinder rod having an upper support plate 32. It is installed so as to be located between the lower support plate 33 and the cylinder rod of the hydraulic cylinder 35, the oil supply plate 36, two pressure plates 37 are sequentially mounted from the bottom portion is mounted Plate-shaped bracket (38) is fastened and fixed hydraulic cylinder With the operation of the (35) consists of a configuration that is to move up and down.

In particular, the oil supply plate 26 which is in direct contact with the valve body is formed in the form of c so as to be in close contact with the oil inlet formed along the outer end while avoiding interference with various valves configured in the center of the valve body. The bottom surface of the valve body is provided with a number of oil holes corresponding to the positions corresponding to the oil inlets of the various valves constituting the valve body, for example, the pressure regulating valve and the directional valve, so that oil can be supplied to each of the valve bodies. It becomes possible.

In addition, the upper and lower conveying guide means is composed of four guide shafts 39, each of these guide shafts 39 between the upper support plate 32 and the lower support plate 33 is vertically It is installed so as to be fastened and fastened, and the inner side of the column 31 supporting the upper support plate 32 and the lower support plate 33 is composed of a configuration that is installed in a mutually symmetrical form, for example, a rectangular symmetrical form.

Therefore, the respective corner portions of the bracket 38 are respectively penetrated to the four guide shafts 39 on both front and rear sides through the bearing 40, so that the bracket 38 according to the operation of the hydraulic cylinder 35 can be obtained. And, in particular, the oil supply plate 36 and the two pressure plates 37, which are integrally formed with the guide plate 39, can be guided correctly by the guide shaft 39.

In addition, in the valve body fixing means, the body level plate 41 and the pin fixing plate 42 are sequentially stacked on the upper surface of the lower support plate 33, and a plurality of body fixing pins 43 serving as a jig thereon are provided. It consists of a vertical installation with a certain position. For example, (b) of FIG. 2 of the accompanying drawings shows the configuration of the installation position of the body fixing pin 43 well, that is, the pin fixing plate 42 and the body level which are stacked on the center of the lower support plate 33 in the upper and lower layers. The plate 41 is placed and a number of body retaining pins 43 (eg, seven body retaining pins 54 are installed in the embodiment of the present invention) across the front of the pin retaining plate 42. When installed under the transmission case, they are installed at positions set to fit the seat surface for fastening the bolts.

In addition, the hydraulic pressure supply means that the sensor block 45, which is equipped with a predetermined number of hydraulic sensors 44, by using the posts 49 on both sides of the hydraulic cylinder (above the upper and lower brackets 38 of the transfer means ( 35 is installed to the rear of the main body base 102, the hydraulic block 20B having three connectors 46 on the upper and lower sides and integrally move up and down with the bracket 38, respectively. For example, the sensor block 45 and the hydraulic block 20B are installed and fixed to the outside of the column 31 positioned on the left side of the upper and lower transfer means, and the oil cleaner 47 for removing impurities contained in oil is provided. The oil tubes 48B and 48C extend from the two other connectors 46 of the hydraulic block 20B at the same time and are interconnected by the oil tube 48A with the oil tubes 48A and 48C respectively. It consists of a configuration that is connected to the upper and lower ports (35-1) each has.

In addition, the sensor block 45 and the hydraulic block 20B are fixedly installed by posts 49 on both sides, and in particular, the hydraulic sensor 44 mounted on the sensor block 45 is the sensor block 45. It is mounted side by side in the longitudinal direction of the oil transport pipe 50 is extended from each of the hydraulic sensors 44, the oil supply via the two pressing plates 37 of the upper and lower transfer means Three oil pipes (3) connected to the plate (36) and mounted on the lower side of the hydraulic block (20B) are connected from the hydraulic block (20A) of the valve body drive system (10). 17D, 17E, and 17F) are respectively bound.

In addition, the components of the upper and lower conveying means, the upper and lower conveying guide means and the valve body fixing means except for the hydraulic cylinder 35 in the valve body mounting system 30 are three transparent windows 51 and one surface. Since it is sealed by the housing 53 which has the transparent door 52, it is possible to prevent the oil from scattering to the outside during operation. That is, the housing 53 is a box on the main body base 102 to be wrapped around the four columns 31 supporting the upper support plate 32 and the lower support plate 33 of the upper and lower transfer means. Type housing frame 53-1 is installed, and both sides and rear side of the housing frame 53-1 are closed with a transparent window 51 so that the operator can observe the working situation therein and at the front of the valve It is made of a structure closed with a transparent door 52 for mounting and removal of the body.

Referring to the operation of the valve body mounting system 30 configured as described above, the valve body is first mounted on the valve body mounting system 30. That is, the O-ring of the LOW-REVERSE BREAKE oil pressure passage in the upper center of the valve body is installed and the manual shift control valve is installed deeply in place. In addition, four solenoid valves, which are mounted together on one side of the valve body, for example, a pressure regulating solenoid valve, a shift switching solenoid valve, and the like, face upwards, and the manual valve faces the front. It is placed on the body fixing pin 43 of the valve body fixing means.

At this time, the position of the valve body is adjusted so that the bolt connection seat surface of the valve body and the body fixing pin 43 are exactly matched, and the connector connected to each solenoid valve of the valve body is firmly engaged with the connector of the mission. When the mounting of the valve body is completed, the front transparent door 52 of the sealing housing 53 is closed and the load item or the comprehensive test of the individual operation is executed in the operation menu.

Therefore, when the execution key is operated in the control board 103 of the valve body tester 100 of the present invention, the drive motor 13 of the valve body drive system 10 starts to drive, and at the same time, the valve body mounting system 30 When the hydraulic pressure is supplied to the hydraulic cylinder 35 of the cylinder cylinder of the hydraulic cylinder 35, the bracket 38, the two pressure plates 37, and the oil supply plate 36, which are coupled with the hydraulic cylinder 35, are lowered and the valve body is lowered. At this time, the sensor block 45 which is integral with the bracket 38 is lowered together.

At this time, the descending process is made while receiving the guide of the guide shaft 39, which is bound to both sides of the bracket 38 before and after, while the lowering operation is performed while maintaining a horizontal state before, after, and left and right without shaking. You lose.

Thus, when the oil inlet surface of the valve body and the bottom surface of the oil supply plate 36 are brought into contact with each other, the hydraulic cylinder 35 pushes the bracket 38 and the two pressure plates 3 with high pressure. The valve body and the oil supply plate 36 are further compressed to prevent the oil from leaking between the upper and lower coupling surfaces.

At this time, until the valve body and the oil supply plate 36 are completely in contact with each other, the oil supply plate 36 is driven at a low pressure and at the same time the two members are completely in contact with each other, and the oil supply plate 36 is installed on one side upper support plate 32 of the hydraulic cylinder 36. Valve body and oil supply plate 36 from the moment the detected proximity switch 54 detects the lower limit position of the sensor block 45 representing the stroke of the hydraulic cylinder 36, for example, the forward limit position of the cylinder rod or the cylinder piston. Are pressed together at high pressure. However, if the valve body is not mounted on the body fixing pin 43 correctly or unstable, the proximity switch 54 does not sense the forward limit position of the hydraulic cylinder 36 and thus the oil supply plate 36. Since high pressure cannot be applied, a large pressure acts in a state in which the valve body is incorrectly mounted as described above, thereby preventing damage to the valve body or the oil supply plate 36.

As described above, the installation of the valve body is completed through the operation of the upper and lower conveying means, the upper and lower conveying guide means and the valve body fixing means in the valve body mounting system 30, and the operation of the manual lever operation unit 60 to be described later. When the binding between the manual valve of the valve body and the locking body 69 of the manual lever control unit 60 is completed, the oil is supplied to the valve body through the hydraulic supply means.

That is, the oil sent to the hydraulic block 20B of the valve body mounting system 30 by the three oil tubes 17D, 17E, and 17F of the valve body drive system 10 is the oil distribution in the hydraulic block 20B itself. According to the function, some of the oil is used as the working fluid of the hydraulic cylinder 36 as described above through the oil tube 47B, and the oil tube 48A is removed after impurities are removed while passing a certain amount through the oil cleaner 47. The oil supply plate 36 through the oil transfer pipe 50 by the intermittent action of the hydraulic sensor 44 is sent to each of the hydraulic sensors 44 of the sensor block 45 through which the opening and closing is selectively made, Then, the oil supply to the oil inlet of the valve body is made, and the oil supplied to the valve body is written into the working fluid of each valve according to the corresponding inspection item, and then again the oil storage tank of the valve body drive system 10. Unlucky as (11) It is.

On the other hand, Figure 2 is a plan view of the valve body tester 100 of the present invention, showing the configuration of the manual lever operation unit 60 installed in front of the valve body mounting system 30.

The manual lever operation unit 60 has a control function for the manual valve of the valve body mounted on the valve body mounting system 30. That is, as shown in the sectional side view of the configuration of the manual lever operation unit 60 shown in FIG. 5, the structure has two plate-shaped supports inside the case body 61 fixedly installed on the main body base 102. The bracket 62 is installed vertically toward the front and the rear, and at the same time, a motor such as a step motor 63 is fixedly installed side by side, and is horizontally penetrating the front and rear support brackets 62 therebetween. Guide pins 63 which are horizontally movable upwards and ball screws 65 which are rotatable downwardly are installed in parallel to each other, and the guide pins 64 and the ball screws 65 are ball nuts. The belt pulleys 68 are attached to the motor shaft 67 of the step motor 63 at the same time as the one side front end of the ball screw 65 and are mutually bound by the 66, respectively. To the structure connected by the electric medium There adjuster.

Accordingly, when the step motor 63 is rotated by a predetermined step, the ball nut 66 is moved forward or backward in one direction by the electric contact of the ball contained between the ball screw 65 and the ball nut 66 and guided together. The pin 64 is also moved forward and backward.

In particular, the front end of the guide pin 64 is equipped with a locking body 70 which is mutually engaged with the manual shift control valve of the valve body to control the operation of the manual shift control valve. That is, the locking body 70 is a ring-shaped lever stopper 71 to be caught directly to the locking port (not shown) of the manual shift control valve and the height of the lever stopper 71 is adjusted by adjusting the height. The main body is composed of a handle 72, a buffer spring 73, and a body 74 having these built-in. When the guide pin 64 is advanced, the lever stopper 71 at the top end of the manual shift control valve As it is pushed forward against the rear end and is caught by the recessed recess of the inside thereof, it is integrally controlled with the guide pin 64 which is moved forward and backward in accordance with the driving of the step motor 63.

In more detail, when the valve body is mounted on the body fixing pin 43, which is the valve body fixing means of the valve body mounting system 30, the control board 103 of the valve body tester 100 is operated. The step motor 63 starts to be driven, and the locking body 70 of the guide pin 64 is engaged with the manual valve of the valve body through the linking operation of the ball screw 65 and the guide pin 64. In this state, after the duty test and the hydraulic test are performed on the valve body, the manual valve, which is integrally engaged with the guide pin 64, is reversed to the L position according to the reverse rotation driving of the step motor 63. If it is moved, the reference point is set at the operating point of the proximity sensor, and the motor is advanced again according to the forward rotation of the step motor 63, and then moved to the D or P position, and other tests in this state are performed.

At this time, in the process of binding with the locking body 70 and the manual valve of the guide pin 64, if the above-mentioned binding state is made before the valve body is completely fixed, the hydraulic pressure of the valve body mounting system 30 When the cylinder 35 is operated, the binding state is incorrect, so the function of the manual lever control unit 60, especially the forward and backward operation of the guide pin 64, is excessively loaded, so that the movement is not smoothly performed. You need to check the status.

Next, as described above, various test items for the valve body mounted on the valve body mounting system 30 are selected and performed, and then the equipment control for determining whether the valve body is defective with the test result value at this time and outputting the same. Referring to the system 80, the equipment control system 80 is the operating state of each valve of the valve body by means of a test condition input means through a connector connection connecting each valve of the valve body and the main computer It is input to the main computer (not shown), which is one of the representative test value comparison and analysis means, and the main computer determines whether the valve body is abnormal by comparing with the preset reference value based on the input value. The test result value or graph is configured to output control to the monitor 81 or a printer (not shown).

Here, looking at an example of a precision divider for generating a duty signal as one of the test value input means, the precision divider is to control the PCSV and DCCSV using the duty cycle (DUTY CYCLE) of the solenoid valve of the valve body In order to obtain an accurate duty signal for generating a frequency of 35HZ. That is, the pulse signal output from the precision divider for duty signal generation or the shift instruction signal transmitted from the computer is output through the solenoid valve driving circuit which is a current amplifying circuit to drive the solenoid valve of the valve body. The precision dispenser means a means for driving the valve body, and thus means for measuring the operating state of the solenoid valve, for example, a hydraulic sensor (converts oil pressure into an electrical signal), A / D.
