Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a work transfer / positioning device for positioning and mounting a work transferred by a work transfer device on a work mounting portion such as a mold.

[0002]

[Prior art]

 As an example, an apparatus for conveying a work such as a metal part to a mold for insert molding is shown in FIG. 2 and will be described below. First, an insert work 102 such as a metal member is placed inside the mold 101 to form a cavity 103 for molding a molded product. A positioning pin 104 for accurately positioning and fixing the insert work 102 is fixed inside the cavity 103. Further, inside the cavity 102, there is formed a loose fitting hole 105 into which a second positioning pin attached to a work transfer device described later is loosely fitted.

On the other hand, a second positioning pin 108 that performs accurate positioning when holding the work 102 is fixed to the work holding member 107 of the work transfer device 106. The work transfer device 106 is fixed to a tool shaft of a robot or an automatic machine. Further, as shown in FIG. 3, the insert work 102 is provided with a hole 102a into which the mold side positioning pin 104 is loosely fitted and a hole 102b into which the second holding pin 108 on the work holding member side is fitted. ing.

[Problems to be solved by the device]

 In general, many insert works 102 have holes formed in advance. Therefore, the positioning pins 104 of the mold 101 are fixed to the positions of the holes by using the holes. However, the second positioning pin 105 of the work holding member 107 must be newly installed, and the hole 102b into which the second positioning pin 105 is inserted must be formed in the insert work 102. It was As a result, the cost of manufacturing the work transfer device and the cost of processing the holes of the insert work were high, and the finished product was also expensive.

[0005]

[Means for Solving the Problems]

 The present invention is intended to solve the above problems, and a work positioning member is provided on a work mounting portion such as a die, and a work positioning hole into which the work positioning member is fitted is provided in the work. A work positioning hole is formed in the work holding member of the transfer device at the same position as the work positioning member of the work mounting portion, and the work holding projection is slidably inserted into the work positioning member of the work mounting portion. Is characterized in that the work holding protrusion of the transfer device is pushed and slid to be fitted into the work positioning hole of the work holding member.

【Example】

 FIG. 1 shows an embodiment of the present invention, which will be described below. First, an insert work 2 such as a metal member is placed inside the mold 1 to form a cavity 3 in which a molded product is molded. Then, inside the cavity 3, a positioning pin 4 for accurately positioning and fixing the insert work 2 is fixed to the position of the hole 2a formed in the insert work 2 in advance.

On the other hand, in the work holding member 6 of the work transfer device 5 attached to the tool shaft of the robot or the like, the second positioning pin 7 for performing accurate positioning when holding the work 2 has the work positioning hole 11 The flange portion 9 of the head, which is inserted into the work holding member so as not to fall off from the work holding member, is inserted into the hole 12 communicating with the fitting hole 11 and is slidably arranged. The second positioning pin 7 is urged outward by the elastic member 8 so as to always project from the work holding member 6. Further, the second positioning pin 7 is installed at the same position so as to come into contact with the positioning pin 4 of the mold 1. Reference numeral 10 is a suction hole for sucking and holding the insert work 2, and the holding means of the insert work 2 can be selected from appropriately known means such as an open-close type chuck claw and an electromagnet type.

Next, the operation will be described. The insert work 2 is positioned by the second positioning pin 7 from a work magazine or the like, and is conveyed above the mold 1. Next, the work holding member 6 (work transfer device 5) is lowered, and the second positioning pin 7 comes into contact with the positioning pin 4 on the die side by this lowering operation. When the work holding member 6 is lowered in this state, the second positioning pin 7 is fitted into the work positioning hole 11 of the work holding member 6 against the elastic member 8. This completes the transfer of the insert work 2 into the mold.

In the present embodiment, the work in which the insert work is preliminarily formed with holes is targeted, but one hole may be processed even if the holes are not formed in advance. That is, in the present invention, the work positioning hole in the work transfer device and the work positioning hole in the die are made the same (also used).

[0010]

[Effect of device]

 According to the present invention, a work positioning member is provided on a work placing portion such as a die, and a work positioning hole into which the work positioning member is fitted is provided in a work. A work positioning hole is formed at the same position as the work positioning member of the mounting part, and the work holding projection is slidably inserted, and the work positioning member of the work mounting part is the work holding projection of the transfer device. Since it is pushed and slid to fit into the work positioning hole of the work holding member, a work positioning pin is inserted into the work in addition to the mold side positioning pin. Since neither an insertion hole is provided separately nor a recess is provided on the die side, the device and the work itself can be manufactured at low cost, and the product itself can also be provided at low cost.
