Description

Automatic Burr Rejecting Apparatus of Union I Using Flexible Jig}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic burr removal device for a union eye using a flexible jig, and in particular, a burr generated during internal diameter processing of a union eye used for a fuel supply hose of a vehicle fuel supply line is flexible. ) It is related with Union Eye Automatic Burr Removal Device which can be removed automatically without using the jig by using Jig.

Union Eye, for example, is a type of connector that is used to supply gasoline to an engine, mounted on a fuel supply hose that connects to the engine from a fuel tank of a small car.

The process of the union eye processing is roughly described. First of all, the raw material is supplied to finish the outer diameter machining and the counter boring process in the bar feeder, and then the inner diameter is processed to the micron precision and The burr is automatically removed by drilling.

Figure 1 is a perspective view showing a process for removing the burr by drilling the inner diameter groove of the union eye, the union eye 30 is supplied to the burr removing device from the vibrating parts feeder (31) The burr 30b was removed by using the drilling machine 34 after the position was set at the machining position of the burr removing device by a pair of fixing jigs 32 and 33 installed on the bottom surface 35 where the position was fixed.

In this case, the orientation of the union eye 30 must be accurate as shown in FIG. 2 so that the burr 30b can be removed by processing within an error range that satisfies the specification.

However, even if a micron error occurs, the central axis 40 of the union eye 30 is largely deviated from the processing shaft 41 of the burr removing device as shown in FIG. There is a problem that the poor processing occurs frequently.

This is because the hole 30a of the union eye 30 is perpendicular to the micron precision at the orientation of the reamer (end mill) 34a of the drilling machine 34 during the drilling operation for removing the burr. This is because it is necessary to change the direction of the union eye while firmly supporting the union eye 30 by the fixing jigs 32 and 33 on the reference surface (bottom surface) 35 in the state. Accordingly, variations can occur in three parameters: the direction of the reamer 34a, the vertical angle of the union eye hole 30a, and the bottom 35 horizontal.

However, when Union Eye's product is mounted on the fuel supply line of the vehicle and used, if the defective workpiece is used, it is a safety-related component that can cause the fire of the vehicle and damage the passengers. It is required to set the machining defect rate of to zero.

Therefore, in order to meet the requirements of the industry, the machining defect rate should be zero, but burr generation is a variable that has a decisive effect on quality in Union Eye's production process. In order to meet these stringent processing conditions, burrs have been manually removed. That is, conventionally, the union eye 30, which is processed in an automatic lathe, is supplied with a reamer (end mill tool) 34a on a drilling machine 34, and the worker rotates the medium eye in a state of rotating the union eye 30. The burr 30b was removed by directly pushing the reamer 34a to change the position of the left and right sides up and down.

Therefore, the conventional processing method has a problem that can cause an increase in manufacturing cost and lower price competitiveness due to low productivity, employment of high-skilled workers, damage to workers due to manual work.

Accordingly, the present invention has been made in view of the problems of the prior art, the purpose of which is to remove the burr of the union eye automatically in the state of supporting the union eye using a flexible jig of the burr generated during the inner diameter processing of the union eye It is to provide Union Bur automatic removal device that can be processed without generating defective products.

For example, it is installed using a proximity switch.

In addition, the flexible jig device 70 for supporting the clamping device 60 to be able to flow in the left and right and up and down directions about the axis within a limited range of the lower surface is disposed on the upper surface (20a) of the support frame 20 and the center A large through hole 9a is formed in the groove, and a circular groove 9b is formed upward in the periphery adjacent to the through hole, so that a plurality of balls 8 can flow from side to side within the 0.1 mm range in the groove 9b. The outer circumferential part is supported by the fixing plate 13 for the ball supporting plate 9 which accommodates this. The fixing plate 13 is fixed by a plurality of fixing bolts on the top of the support frame 20.

The upper portion of the ball support plate 9 is accommodated at intervals of 0.1 mm each from the left and right of the through hole 9a of the ball support plate 9, and the bottom surface of the outer circumference portion flows to the plurality of balls 8. A first flow plate 7 is placed which is possible. In this case, since each ball 8 has a diameter larger than the depth of the groove 9b, the first flow plate 7 is movably supported on the ball support plate 9 with low frictional force.

In addition, the first flow plate 7 has a cylindrical columnar portion 7a extending upward from the center, and through the center of the cylindrical columnar portion 7a through the union eye 30 by the reamer 34a. The burr discharge hole 10 for discharging the burr 30b removed from () is formed.

The operation of the automatic burr removal device of the union eye according to the present invention configured as described above will be described in detail.

First, when the start switch of the automatic burr removal device is turned on, the reamer 34a of the drilling machine 34 starts to rotate by an internal rotary motor, and at the same time, a plurality of union eyes 30 to be burred are processed. ) Is supplied to the vibrating parts feeder 31, the union eye 30 is automatically aligned by the vibration is transferred along the guide rail 36 to the processing line position as shown in FIG.

The drive cylinder 1 of the loading / unloading device 50 then moves the piston forward until the position sensor S2 detects the forward position of the piston. Accordingly, the supply guide jig 2 installed at the distal end of the piston rod 1a supplies the union eye 30 to the machining position, and when the position detecting sensor S2 detects the forward position, the controller of the control system responds thereto. The feed guide jig 2 of the drive cylinder 1 is reversed, and the fixing cylinder 4 is operated to advance the movable support member 3 so as to move with the recess 12a of the fixed support member 12. The union eye 30 is fixedly supported between the grooves 3a of the support member 3.

When the position sensor S4 detects the advance of the piston in accordance with the advancement of the movable support member 3, the controller recognizes that the union eye 30 is fixed and the driving cylinder 34b of the drilling machine 34 is completed. ), The reamer 34a is lowered until the position detecting sensor S6 detects that the piston reaches the lowered position.

In this case, the reamer 34a has a diameter of 12.26mm and rotates about the processing shaft 41 and descends, and the union eye 30 to be burnished has an inner diameter of 12.3mm and is about 0.02 in the upper and lower portions of the inner circumference. It is fixed by the clamping device 60 in the state in which the burr 30b protrudes in mm length.

Accordingly, as the reamer 34a descends downwardly through the hole 30a of the union eye 30, a plurality of vertical blades 34c formed on the outer circumference of the reamer 34a come into contact with the burr 30b to bring the union eye into contact with the union eye. A downward momentary force is applied to the 30 and at the same time a rotation moment is applied in the rotational direction of the reamer 34a.

After that, when the position sensor S6 detects the lowered position of the piston, the drive cylinder 34b is driven in the opposite direction according to the control of the controller until the position of the piston is detected by the position sensor S5. Emer 34a is raised. When the reamer 34a rises to its original position while rotating in the lowered position, the upward moment is applied to the union eye 30 and the remaining burr 30b, and a rotation moment is applied.

However, the clamping device 60 supporting the union eye 30 is fixed to the second flow plate 14 in which the fixed support member 12 and the movable support device 61 can move left and right and up and down, and have a second flow. Since the plate 14 is ball-socketed to the column portion 7a of the first flow plate 7 which can flow left and right, the union eye 30, the clamping device 60, and the flexible jig device 70 are described above. According to one rotational moment, the movement is left and right within the above limited range, that is, 0.1 mm range, and in particular, the union eye 30, the clamping device 60, and the second flow plate ( 14) the left and right and up and down movement is made at the same time.

Therefore, the union eye 30 moves in a limited range to the left and right and up and down in conjunction with the falling and rising of the reamer 34a, so that the upper and lower burrs 30b formed on the inner circumferential surface of the union eye 30 are completely removed. It falls to the burr collection hole 20b of the support frame 20 through the burr discharge hole 10 of the first and second flow plates 7 and 14.

In this case, since the whole of the flexible jig device 70 receives the rotation moment in the state in which the flow is possible, the center axis 40 of the union eye 30 is 0.1 to the left and right about the machining axis 41 of the reamer 34a. It was confirmed that a number of experiments resulted in setting the flow width of mm to achieve the optimum burr removal without cutting the inner circumference of the union eye 30.

On the other hand, when the rising position of the piston is detected by the position detecting sensor S5, the operation of the driving cylinder 34b is stopped, the fixing cylinder 4 is operated to reverse the movable supporting member 3, and the processed union is completed. Unlock the child 30.

Subsequently, when the position detecting sensor S3 detects the backward of the movable support member 3, the controller determines that one cycle of the one union eye 30 is completed and repeatedly loads / unloads from the beginning of one cycle of machining. The loading device 50 is driven. Accordingly, as the new union eye 30 is transferred to the machining position, the union eye 30 is pushed out of the finished union eye 30 and is automatically stored in the product box.

When the burr processing process is repeated under the control of the controller, the union eye 30, which has been processed, has a defect rate of zero, and productivity can be improved by about 3.6 times as compared with the conventional one. The product is processed completely automatically without the need.

As described above, the present invention can process a product with high productivity without the occurrence of defective products by automatically removing the burr of the union eye while supporting the union eye using the flexible jig of the burr generated during the inner diameter processing of the union eye. .

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and is not limited to the spirit of the present invention. Various changes and modifications can be made by those who have
