Description

Forgings Curve Inspection Device {Forgings Curve Inspection Device}

The present invention relates to a device for checking the bending state of the forging, and more particularly, the fixing chuck is coupled to the table so that the forging rod is rotated in a coupled state, and the coupling rod is configured to be rotatably coupled to the upper surface of the table to be spaced apart from the fixing chuck. The gauge is in contact with the outer circumferential surface of the forged bar to be rotated by combining the mounting rod with a mounting bracket using a bracket provided with a gauge for measuring the bending state in contact with the outer circumferential surface of the forging rod to be measured when the rod is rotated in the fixed chuck direction Since the bending of the forging rod is measured at, the bending of the forging rod can be precisely measured and the processing of the universal joint, which is a post-processing, can be easily performed by using the forged rod that has been measured. Install a control rod at the bottom to contact the stopper Thus, the gauge equipped with the measuring rod installed on the mounting rod can always measure the bending or groove or unprocessed portion of the forging rod at the same rotation angle, while increasing the reliability of the measurement value, and the measuring instrument can be rotated forging Since the entire outer circumferential surface of the rod is measured, the bent or grooved or unprocessed portion can be accurately measured by the measurer and displayed through a gauge.The fixed chuck combined with the forged rod to be measured by the rotating means is automatically rotated. As the measuring device measures the bending of the forged bar to be measured while being moved to the upper and lower parts of the rod by the lifting means, the measuring part can be used to reduce the measurement error while measuring the forged bar part to be measured. Accurately measure by the operator and display through the gauge It relates to a forged warpage inspection apparatus.

In general, the universal joint is to transmit the rotational force of the steering wheel of the vehicle to the steering column, the universal joint is connected to the pinion gear shaft to transmit the rotational force of the steering column to the pinion gear shaft.

In addition, the rotational force of the pinion gear is converted into a linear motion through the rack gear is transmitted to the left and right wheels through the rack bar to generate a steering force.

That is, the universal joint is installed between the column module coupled to the steering wheel and steering column to generate a rotational force, and the chassis module coupled to the gear box and suspension to operate the wheel.

Universal joint for steering device of the vehicle is coupled to the column module to generate a rotational force, a driven yoke that receives the driving force of the drive yoke and transmits to the chassis module, and transfers the rotational force between the driven yoke and the drive yoke At the same time, the slip joint is configured to allow slip.

7 illustrates a conventional universal joint, and reference numeral 200 denotes a universal joint.

The universal joint 200 is roughly divided into the yoke 210 and the connecting rod 220 to which the yoke 210 is coupled.

The yoke 210 is coupled to one end of the connecting rod 220 constituting the universal joint 220 in the '' 'shape, the fastening hole 211 is formed on both sides of the yoke 210.

In this way, a spline 230 having a mount 231 and a groove 232 is formed in the connection rod 220 to which the yoke 210 having the fastening hole 211 is coupled.

The spline 230 is formed on the outer circumferential surface of the connecting rod 220 as shown in (a) of FIG. 7 or is formed on the inner circumferential surface of the connecting rod 220 as shown in (b) of FIG.

That is, when the connecting rod 220 is formed on the solid shaft as shown in Figure 7 (a) is formed on the outer peripheral surface of the connecting rod 220,

As shown in FIG. 7B, when the connecting rod 220 is formed on the hollow shaft, the connecting rod 220 is formed on the inner circumferential surface of the connecting rod 220.

Therefore, although the connecting rod 220 with the spline 230 is not shown in the drawing, the steel ball is internally coupled to the spline tube so that the steering force is transmitted to the sharp module so that the driver can drive in the desired direction. For this reason, it is important that the forged rod (P1) forged before the spline 210 is formed is precisely forged vertically.

That is, if the forged bar (P1) is forged to be bent to one side as shown in Fig. 8 (a), as shown in Figs. 7 (a), (b) by the bent portion of the forging bar (P1) The spline 230 may not be formed on the outer circumferential surface and the inner circumferential surface of the connecting rod 220, and thus, the rotational force of the steering wheel may not be accurately cut by the pinion gear shaft.

In addition, the forged bar (P) is not forged to produce a spline 230 at the same depth by the groove during the forging process so that the groove is generated, as shown in Figure 8, because of the pinion gear as described above There was a problem that could not be correctly transferred to the axis.

In order to solve such a problem, the problem of the conventional forged bending state inspection device is that the forged bar (P1) is only measured with the naked eye, so that the bending or the groove of the forged bar (P1) cannot be easily measured. Was done.

In addition, in order to solve this problem, the bending of the forged bar (P1) forged by using a ruler formed in a straight line is measured, but when the bending portion of the forged bar (P1) is measured by using the ruler to measure from where Not only do the operators know, but the workers who do not measure the forged parts cannot find it.

The problem of not measuring a plurality of grooves formed in the forging bar P1 is not easy.

Therefore, the present invention for solving the above problems is configured to couple the fixed chuck to the table so that the forged rod is rotated in a coupled state, the mounting rod is rotatably coupled to the table top surface to be spaced apart from the fixed chuck, the mounting rod is fixed chuck The gauge is provided in contact with the outer circumferential surface of the forged bar to be measured when rotating in the direction coupled to the mounting rod using a bracket configured to measure the bending of the forged bar in contact with the outer circumferential surface of the forged bar to be rotated Since it is possible to measure the bending of the forged rod precisely, the finished forged rod can be easily processed by using the forged rod that has been measured, and the table has a stopper and a lower end of the rod installed at the stopper. Install and configure the control rod to be contacted, the side installed on the mounting rod The self-equipped gauge can always measure the bending or grooves or unmachined parts of the forged bar at the same angle of rotation, while reliably measuring the measured value to improve productivity. In addition, the measurer can measure the entire outer circumferential surface of the forged bar being rotated. Therefore, the bent state or groove or unprocessed part can be accurately measured by the measurer and displayed through the gauge, and the fixed chuck combined with the forged bar to be measured by the rotating means is automatically rotated, and the measurer measuring the bending of the forged bar Since the bending of the forged bar to be measured is measured by moving the upper and lower parts of the rod by lifting means, the measuring part can measure the forged bar part to be measured accurately by the measurer while reducing the measurement error. Forged warpage for display through It is an object to provide an inspection apparatus.

The present invention precisely measures the forged (bend or grooved or unprocessed) of the forged bar (P1) forged machining to find the defective product in advance to post-process using the forged bar (P1) It is to make it easy.

At this time, the forged bar (P1) coupled to the fixed chuck 20 is not shown in the figure, but it is revealed that it can be formed in a polygon other than a circle.

In addition, it is possible to measure the bending of the forging bar (P1) in the state in which the measuring device 131 provided in the gauge 130 installed in the mounting rod 100 is rotated to the same rotational position.

The measuring device for measuring the forged bar (P1) is forged from the fixed chuck 20 and the fixed chuck 20 is rotatably coupled to the table 10, the upper surface of the table 10, as shown in FIG.

The fixed chuck 20 to which the precision forged master forging bar P or the forging bar P1 to be measured is coupled forms a chuck coupling part 30 that is bearing-coupled to the upper surface of the table 10 as shown in FIG. 1, The chuck body 40 is coupled to the upper surface of the chuck coupling portion 30 by a bolt.

Since the chuck body 40 is coupled to the upper surface of the chuck coupling portion 30 by using a bolt, the chuck body is provided with a fitting groove 141 made to fit the diameter of the forging bar (P1) to be measured. 40 is easy to replace, the chuck coupling portion 30 is composed of a plurality of rotary knobs 31 at equal intervals to facilitate the rotation of the fixed chuck 20 coupled to the forging bar (P) (P1). Let's do it.

Gauge 130 is provided with a measurer 131 for measuring the bending of the forged bar (P) (P1) coupled to the fixed chuck 20 is installed rod (rotation) installed on the table 10 as shown in FIG. It is coupled to the outer circumferential surface of the 100 using the bracket (120).

The bracket 120 coupling the gauge 130 to the mounting rod 100 forms a coupling hole 180 to force the bracket 120 into the outer circumferential surface of the mounting rod 100 to be coupled to the bracket 2120. At one end of the gap adjusting groove 121 is formed so that the coupling hole 180 is in communication with the coupling end 182 on one side of the bracket 120, by screwing the bolt to the coupling end 182 to the bracket 120 is fixedly coupled to the outer circumferential surface of the mounting rod (100).

The mounting rod 100 to which the gauge 130 is coupled to the bracket 120 is rotated at the upper surface of the table 10 so that the lower end of the mounting rod 100 forms a rotating part 110 which is bearing-coupled with the table 10. And a stopper 140 fixedly coupled to the upper surface of the table 10 to be spaced apart from the rotating part 110, and a stopper capable of controlling a rotation angle of the installation rod 100 that is rotated on the outer circumferential surface of the rotating part 110. 140).

The stopper 140 and the control rod 140 are coupled to the rotary part 110 provided at the lower end of the table 10 and the installation rod 100, respectively, and installed due to the control rod 140 contacting the stopper 141. It is possible to control the rotation angle of the (100), which is due to the gauge 130 as shown in Figure 4 (b) at the same rotation angle measured by the master forging bar (P) as shown in Figure 4 (a) The provided measurer 131 is positioned.

At this time, the rotating part 110 to facilitate the rotation of the installation rod 100 in the direction in which the fixed chuck 20 is formed by forming a rotary knob 111 as shown in Figures 1 to 4.

When explaining the preferred operating state of the present invention configured as described above is as follows.

First, in a state in which the master forging bar P is coupled to the fixed chuck 20, the gauge 130 is set to zero by contacting the measurer 131 provided in the gauge 130 with the forging bar P.

Referring to setting the gauge 130 to zero, the master forged bar (P), which is precisely processed as shown in FIG. 4 (a), is forcibly inserted into the fitting groove 41 of the fixed chuck 20.

When the master forging bar (P) is forcibly coupled to the fixed chuck 20, the operator to measure the forging bar using the rotary knob 111 provided in the mounting rod 100 as shown in Figure 3 (b) By rotating the mounting rod 100 in the counterclockwise direction, the control rod 141 provided in the rotating unit 110 contacts the stopper 140 fixedly coupled to the upper surface of the table 10.

At the same time as the control rod 141 contacts the stopper 140, the measurer 131 provided in the gauge 130 displays the measured value measured on the gauge 130 while contacting the outer circumferential surface of the master forging rod P. , The operator zeroes the measured value displayed on the gauge 130 by using a control switch (not shown).

The structure of displaying the value to be measured on the gauge 130 due to the measurer 131 and the structure of zero setting the gauge 130 by using a control switch (not shown) are well-known techniques and will not be described in detail. Shall be.

After setting the gauge 130 to zero, the operator grasps the rotary knob 111 provided in the rotating unit 110 by hand and rotates the installation rod 100 in a clockwise direction to control the rod 141 in contact with the stopper 140. Depart from.

When the control rod 141 is detached from the stopper 140 and the measuring rod 131 in contact with the forging bar P is released from the forging bar P1.

When the measurer 131 is separated from the master forging bar (P), the operator separates the master forging bar (P) from the fixed chuck 20, the forging bar (P1) to be measured as shown in Figure 4 (b) It fits into the fitting groove 41 provided in the fixed chuck (20).

When the forging bar P1 is forcibly coupled to the fixed chuck 20, the worker uses the rotary knob 110 provided on the rotating part 110 to install the control rod 141 again in contact with the stopper 140. It rotates in the direction installed in the fixed chuck 20 so that the measurer 131 provided in the gauge 130 is in contact with the forging bar (P1) coupled to the fixed chuck 20.

As such, when there is no change in the gauge 130 displaying the measured value in the state in which the measurer 131 is in contact with the forging bar P1 to be measured, the operator hands the rotary knob 31 provided in the chuck coupling part 30. The fixed chuck 20 is rotated in one direction in the state of holding.

At this time, the measurer 131 may measure the bending of the forged bar P1 to be measured to be rotated in a state in which the rotation angle, which is the measuring position, is not changed due to the control rod 141 in contact with the stopper 140.

When the bending occurs in the forging bar P1 to be measured as shown in FIG. 4B, the gauge 131 moves as much as the bending, so that the gauge 130 displays a value to be measured by the measurer 131. Forged rod (P1) is easy to find.

However, if there is no bent portion in the forging bar (P1), the measuring device 131 in contact with the forging bar (P1) is hardly moved, thereby displaying on the gauge 130 displaying the measured value of the measuring device 131 The measured value also hardly changes.

Therefore, the operator is using the measured value displayed on the gauge 130 is whether the forging bar (P1) coupled to the fixed chuck 20 is normally forged or forged bar (P1) forged to be provided with bending, etc. You can judge.

 The forging bar (P1) to be measured as described above is measured by the forging bar (P1) of the forging bar (P1) measured by the measurer 131 provided in the gauge 130 in a state of being coupled to the fixed chuck 20 to be rotated ( Not only can P1) be precisely measured, but the effect of reducing the measurement time of the forged bar P1 to be measured can be expected.

In addition, the measurer 131 provided in the gauge 130 is the same rotation angle by the stopper 140 provided on the table 10 and the control rod 141 provided on the rotating unit 110 of the mounting rod 100. Since it is measured in, the position of the measuring device 131 to be measured of the forging bar (P1) can be prevented to the maximum, and thus the measured value of the forging bar (P1) displayed on the gauge 130 is reliable. By using the forging bar (P1) it can be expected to effect the effect of facilitating the processing of the universal joint is post-processing.

On the other hand, Figure 5 and Figure 6 is a forging bar (P) coupled to the fixed chuck 20 by installing a rotating means 50 and the lifting means 150 in the measuring device for measuring the forging bar (P1) of the present invention ( While rotating the P1) automatically, the operator 131 to measure the portion that the operator wants to measure the gauge 130.

The rotating means 50 is to automatically rotate the fixed chuck 20 is coupled to the forging rod, elevating means 150 is the installation height of the gauge 130 is provided with a measuring device 131 coupled to the mounting rod 100 To vary.

The rotating means 50, the rotary motor 70 is installed inside the table 10;

The connecting gear 61 is connected to the drive gear 71 provided in the rotation motor 70, the rotation shaft 60 is formed in the lower center of the fixed chuck 20;

The lifting means 150, the shaft hole 101 penetrating the center of the installation rod 100;

A lift motor 160 installed inside the table 10,

Rotating rod 170 is rotated by receiving the rotational force of the lifting motor 160, the bearing is coupled to penetrate the shaft hole 101;

A first screw thread 172 formed on the upper outer circumferential surface of the rotary rod 170;

A second screw thread 181 screwed to the first screw thread 172 is provided on an inner circumferential surface thereof, and is formed in the bracket 120 to allow the rotating rod 170 to pass therethrough;

The lower end is coupled to the rotating part 110 provided in the lower portion of the installation rod 100, the upper portion is coupled to penetrate through the bracket 120, the bracket 120 in the direction in which the rotating rod 170 is rotated, up and down A guide rod 190 for guiding vertical movement; characterized in that configured.

At this time, the rotary motor 70 constituting the rotating means 50 and the lifting motor 160 constituting the lifting means 150 are on / off by the control signal of the controller 1.

In addition, the rotation means 50 is provided with a contact sensor on the stopper 140 and the control rod 141 so that the control unit 1 operates the rotary motor 70 only when the stopper 140 and the control rod 141 are in contact with each other. It can be said.

When described the operating state of the combined rotation means 50 and the lifting means 150 configured as follows:

First, when the measuring height of the forging rod (P) (P1) coupled to the fixed chuck 20 and the height of the measuring member 131 of the gauge 130 coupled to the mounting rod 100 by the bracket 120, the same, The operator sets the gauge 130 to zero by contacting the measurer 131 with the outer circumferential surface of the master forging rod P coupled to the fixed chuck 20.

When the gauge 130 is set to zero, the operator stops the control rod 141 coupled to the rotating part 110 of the mounting rod 100 in a state in which the forging rod P1 to be measured to the fixed chuck 20 is coupled to the stopper 140. Rotate the mounting rod 100 in the direction of the fixed chuck 20 to be in contact with.

At the same time as the control rod 141 is in contact with the stopper 140, the measurer 131 is in contact with the outer circumferential surface of the forging rod (P1) to measure the bent portion of the forging rod (P1) to be displayed on the gauge 130.

If the measured value displayed on the gauge 130 is hardly changed due to the measurer 131, the controller 1 sends a control signal to the rotary motor 70 installed inside the table 10 to operate the rotary motor 70. On works.

The rotational force of the rotary motor 70 is transmitted to the rotary shaft 60 provided with the connecting gear 61 engaged with the drive gear 71 of the rotary motor 70 fixed chuck coupled to the upper portion of the rotary shaft 60 It is to rotate the 20 in one direction.

Therefore, the measuring device 131 in contact with the outer circumferential surface of the forged bar (P1) is rotated by measuring the bent or the like of the forged bar (P1) in contact with the forged bar (P1) is rotated through the gauge 130 To be displayed.

If the measured value displayed on the gauge 130 does not change due to the measuring member 131 measuring the forged bar P1 being rotated, the forged bar P1 is normally forged and manufactured.

When the measured value displayed on the gauge 130 is changed by the measurer 131, the forging bar P1 is manufactured to be defective.

On the other hand, the measuring position of the forging bar (P) (P1) coupled to the fixed chuck 20 and the installation height of the gauge 130 with the measuring rod 131 coupled to the mounting rod 100 by the bracket 120 is mutually If it does not match, the control unit 1 sends a control signal to the lifting motor 160 of the lifting means 150 installed inside the table 10 to operate the lifting motor 160 On.

The rotary rod 170 having the connecting gear 171 connected to the driving gear 161 of the elevating motor 160 receives the rotational force of the elevating motor 160 and rotates forward and reverse in the left and right directions as shown in FIG. 6. do.

At this time, since the rotary rod 170 is bearing-coupled to the shaft hole 101 provided in the installation rod 100, only the rotary rod 170 is rotated by receiving the rotational force of the elevating motor 160.

Due to the rotation of the rotating rod 170, the bracket 120 screwed to the upper portion of the rotating rod 170 is moved up and down along the guide rod 190 coupled to the bracket 120, the gauge of the gauge 130 (131) The installation height can be changed.

That is, a first thread 172 is formed on the outer circumferential surface of the rotating rod 170, and a second thread 181, which is screwed to the first thread 172, is provided in the coupling hole 180 provided in the bracket 120. To form.

The guide rod 190 penetrating the bracket 120 is coupled to the upper surface of the rotating part 110 provided at the lower end of the installation rod 100.

Therefore, regardless of the direction in which the rotating rod 170 is rotated, the screw-coupled bracket 120 moves up and down along the guide rod 190 while being coupled to the rotating rod 170 by the bracket 120. The measurer 131 is to vary the installation height.

As such, the control rod 141 is moved to the stopper 140 after moving the installation height of the gauge 130 provided with the measurer 131 to the height of the forging bar P1 to be measured by the operator using the lifting means 150. The installation rod 100 rotates in the direction in which the fixed chuck 20 is coupled to be in contact.

At the same time as the control rod 141 is in contact with the stopper 140, the measurer 131 provided in the gauge 130 measures the bending of the forging rod P1 while being in contact with the outer surface of the forging rod P1. If there is no change in the gauge 130 displaying the measured value measured from the measurer 131, the control unit 1 sends a control signal to the rotary motor 70 constituting the rotating means 50 to rotate the rotary motor 70 On to operate the fixed chuck 20 received the rotational force of the rotary motor 70 to rotate in one direction.

At this time, the measurer 131 is able to precisely measure the forging bar (P1) to be measured because it maintains the state in contact with the forging bar (P1).

In this way, the rotating means 50 for automatically rotating the forging bar (P1) coupled to the fixed chuck 20 is installed, and the installation height of the gauge 130 is provided with a measurer 131 installed on the mounting rod 100 Since the lifting means 150 is formed, the bending of the forging bar P1 and the like can be automatically measured and displayed on the gauge 130, thereby reducing the measuring time of the forging bar P1. You can expect

In addition, the installation height of the gauge 130 for measuring the bending of the forging bar (P1), etc. can be easily changed to the desired height by the lifting means 150,

Therefore, the operator can measure the measurement of the forging bar (P1) more precisely by using the gauge 130 provided with the measuring device 131 that is moved up and down using the lifting means 150, thereby measuring By using the forged bar (P1) after the completion of the universal joint is processed can be expected to significantly reduce the defective rate.
