Description

{A yoke loading apparatus}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yoke loading apparatus, and more particularly, to a yoke loading apparatus for moving a yoke in a sort and posture to a machining position.

Among the major parts of the automotive electric power steering system (MDPS), the column and the in-shaft are long and complicated, and the precision is high, so that molding is very difficult. However, precision and rigidity are required in manufacturing the automobile.

The torsion joint yoke, which is one of the major components of the steering column, is manufactured by welding a hot-rolled steel sheet after bending the yoke. The yoke is manufactured by welding a ring having a square shape inside to transmit the rotational force of the yoke to the shaft To the inside of the yoke. At this time, when the yoke is bent, an accurate roundness is not obtained. Therefore, the space between the shaft and the yoke is filled with resin to increase the surface pressure so that the shaft and the yoke do not rotate.

However, as described above, since the yoke is welded by bending the plate, there is a problem that only one product is required to be machined in one cycle, resulting in a significant deterioration in productivity. Further, since the weld portion is weak when the yoke is twisted, There is also a big problem to occur.

Moreover, since the product is produced through several component joining operations together with the above-described welding operation, there is a problem that the product cost increases as well as the product cost, and since the yoke is manufactured using the heavy-weight hot-rolled steel sheet, The product is not competitive.

FIG. 1 shows a steering yoke 10 manufactured by forging to solve the above-mentioned problems. The yoke body 11 and the yoke body 11 are connected to each other by a fork And a pair of wing portions 12 and 13 branched and symmetrically formed. A serration hole (14) for connecting to the serration portion (27) of the shaft portion (23) is formed through the yoke body (11). At both end portions of the shaft portion 23, serration portions 25 and 27 are formed, respectively. A cutout 15 is formed in the serration hole 14 to one of the wing portions 12 so that the cutout portion 14 can be inserted into both ends of the yoke body 11, 16 are formed.

A universal joint 21 connected to the steering gear side is coupled to the wing portions 12 and 13. To this end, engagement holes 12a and 13a corresponding to each other are formed at the ends of the wing portions 12 and 13 do.

The wing portions 12 and 13 are formed at equal intervals symmetrically with respect to the center of the serration holes 14 and the yoke body 11 has a serration hole 14, First and second short side faces s1 and s2 and first and second long side faces s3 and s4 on the basis of the center C of the first and second short sides. A bolt coupling hole 16 is formed to penetrate the first and second short side surfaces s1 and s2 and a cutout portion 14 is formed in the first long side surface s3. The first and second short side faces s1 and s2 are formed so as to maintain the same distance from each other with the center c of the serration hole 14 as the center and the first and second long side faces s3 and s4 And are formed at different distances. That is, the first long side face s3 formed with the cut portion 14 is formed so that the distance from the center long side c4 is greater than the second long side face s4 located on the opposite side.

In order to process the yoke 10 having the above-described structure, a forged work piece (yoke structure before machining) is supplied to the machining system and must be precisely machined through various machining steps. In order to achieve this, it is necessary to automatically align and load the workpiece through the automation and supply it to the machining system, thereby improving productivity and precise machining.

Meanwhile, the yoke 10 may have various sizes depending on the type of vehicle to which it is applied. Since the shape of the yoke 10 is asymmetric with respect to the serration hole, it is necessary to supply the yoke 10 in a precise direction and size .

Conventionally, when the worker selects the type (size) of the workpiece by manual operation of the workpiece, determines the posture (direction) of the selected workpiece and mounts the workpiece at the loading position, And the yoke was supplied through a process of picking up and moving it to the machining position.

However, if the worker selects the type of the workpiece by manual operation and determines the direction and stores it, the workpiece to be supplied should not be supplied due to the operator's mistake. If the workpiece is misdirected, There is a problem that a malfunction is caused as well as a failure of the entire system and the operation of the entire system is stopped, and a wrongly inserted workpiece is found and removed. Therefore, not only is it a cause of the system failure, but also the productivity is lowered due to the interruption of the operation, and the cost is increased because the manager has to supply it by hand.

The second sensor 160 is supported on a sensor support bracket 161 installed on the base 50 and is loaded on the yoke seating portion 133a at the second loading position B, And a contact sensor 163 for sensing the size of the yoke 10. That is, the contact sensor 163 is installed on the upper end of the sensor supporting bracket 161 and moves toward the yoke 10 to contact the yoke 10, thereby detecting the size of the yoke 10 based on the moving distance Called " contact probe ". The second sensor 160 may include a non-contact sensor in addition to the contact sensor. The non-contact sensor may be a laser sensor, an ultrasonic sensor, or the like. The second sensor 160 may include a vision sensor (including a camera) It is of course also possible to confirm the size and type of the recording medium 10.

The third loading unit 140 is for picking up the yoke 10 moved to the third loading position C and moving it to a position to be processed, that is, to the index 200. Here, the tertiary loading unit 140 may have various configurations. For example, the tertiary loading unit 140 may have the same or similar configuration as the other components except for the rotary drive unit 127 in the secondary loading unit 130. That is, the tertiary loading unit 140 includes a clamper section 141 for clamping the yoke 10, an elevation driving section 143 for vertically moving the clamper section 141 up and down, and an elevation driving section 143 And a rectilinear driving unit 145 for rectilinear movement.

The clamper part 141 has a clamper 141a that clamps the outer side of the yoke 10 and clamps the clamper 141a and a clamper supporting part 141b that supports the clamper 141a.

The clamper supporting portion 141b is connected to and supported by the elevating driving portion 143 and is moved up and down by the elevating driving portion 143. [

The driving unit 145c may include an LM guider installed between the support frame 146 and the linear movable member 145b. In addition, various types of known actuators may be used.

The third loading unit 140 having the above configuration clamps the yoke 10 moved to the second loading position C by the second loading unit 130 to clamp the predetermined To the mounting position. Here, the specific configuration of the tertiary loading unit 140 is not limited to the present invention, and various modifications are of course possible.

The controller 170 controls the driving of the primary, secondary and secondary loading units 120, 130 and 140 to control the yoke 10 from the yoke hopper 110 to the index 200 in a correct posture. That is, the control unit 170 controls the driving of the primary loading unit 120 based on the information transmitted from the first sensor 150. Specifically, when the yoke 10 'whose direction is changed is detected After the corresponding yoke 10 'is chucked, the rotation driving unit 127 is driven and rotated to rotate at an angle of 90 degrees so that the direction of the yoke 10' becomes a normal direction. Then, the yoke 10 'is moved to the second loading position B to be seated on the yoke seating portion 133a.

When the yoke 10 'is seated on the yoke seating portion 133a, the second sensor 150 is operated to detect the type of the yoke 10'. That is, by sensing the yoke 10 'by the contact method, the size and type of the yoke 10' are confirmed, and the confirmed information is transmitted to the controller 170.

The controller 170 receives the sensing information from the second sensor 150 and determines whether the yoke 10 'is a yoke of a size set to be machined and determines whether the yoke 10' The second loading unit 130 is driven to move the yoke 20 'at the second loading position B to the third loading position C. [

On the contrary, if it is determined that the supplied yoke 10 'is not the kind of yoke set for machining, the control unit 170 outputs an alarm Signal so that the manager or the operator can remove the yoke supplied from the yoke mounting portion 133a by mistake. Here, the output unit 180 may include at least one of a speaker, a warning light, and a display unit. Accordingly, the operator recognizes that the alarm signal, that is, the yoke is erroneously entered through the output unit 180, and separates and removes the yoke 10 'of the yoke seating portion 133a. Therefore, it is possible to prevent another type of yoke from entering the index 200, and to prevent the malfunction of the machining system and the occurrence of breakdowns.

When the yoke 10 'of the set type is moved to the third loading position C, the controller 170 drives the third loading unit 140 to move the yoke 10', which is moved to the second loading position C, 10 ') to the index 200 side.

As described above, according to the yoke loading apparatus 100 according to the embodiment of the present invention, when the yoke 10 is supplied from the yoke feed hopper 110 to the index 200, the yoke feed hopper 110 The direction of the yoke 10 is changed to the second loading position B while the second yoke 10 is moved in the second loading position B to the second sensor 160 So that the kind of the yoke 10 can be confirmed. Accordingly, when a yoke of a different type than that of the set type is supplied, an alarm signal is output through the output unit 180 to be removed by the operator. Before the operator removes the alarm signal, the controller 170 controls the secondary loading unit 130 It is possible to prevent the faulty or malfunctioning of the machining system and to prevent the malfunctioning of the system entirely due to the erroneously fed yoke 10. [ It is possible to fundamentally solve the problems such as stopping the operation of the apparatus, and improve the productivity and productivity of the product.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Those skilled in the art will readily appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.
