Abstract

The present invention relates to a grinding jig configured to easily and precisely grind the heat treatment angle step pins required throughout the injection mold industry. The present invention, which consists of a main body, a movable body, and a spring-loaded pressing plate, rotates a fixed sieve at the center of the main body. The tilt connecting plate connected to the angle control part fitted to the screw rod is connected to the tilted position at the center of the movable body. When the screw rod is rotated, the angle adjusting part reciprocates in equilibrium, and the tilt connecting plate moves at the tilted end. In the present invention configured to rotate the movable body holding the rotating pin fixed to the main body in the movable body to move up and down at an angle, the "∨" grooved support plate is fixedly coupled to the movable body, the pressing plate thereon The fitting protrusion formed at one end is formed in the fitting groove formed at one end of the support plate. When the spring-coupled pressing plate is lifted from the opposite end coupled by the haptic pin, it is configured to move up and down in an angular space with the "∨" groove support plate, and utilizes the work space to pin the "∨" groove that matches the pin size to be ground. Place the spring-loaded presser plate lightly and place the curved surface of the pin on both sides of the groove, and the upper part touches the spring-loaded presser plate lightly. While the pin is rotated at the same time as the grinding stone and slowly rotated to grind, the present invention is configured to grind the angle step pins in accordance with the angle scale engraved on the body by turning the screw rod with a hexagon wrench. Rather than using the angle scale, triangulation is used to calculate the angle and draw the block under the angle calculation pin. It is here results in a double effect features configured to allow a precise angular grinding step pin.

The present invention relates to a "grinding jig" for easily and precisely grinding a small heat treatment angle stepped pin. In detail, the three core parts consisting of a main body, a movable body, and a spring-loaded pressing plate are combined to provide a mutual connection operation. Through this, the angle step pin can be easily and precisely ground.

Conventional mold manufacturing industry uses the method of grinding two square blocks on the magnetic table with a little less than the size of the pin on the magnetic table and pressing them with one hand to turn the pin with the other hand. Not only can not be ground, but the skilled workers have the disadvantages of grinding because of the risk of physical injury.

It is difficult to adjust the angle of the pin, and it is difficult to adjust the angle of the drill by inserting the pin into it and rotating it by inserting the drill hole in one block by the method different from the above. Therefore, when manufacturing the pin with an angle, grinding the grinding stone to the angle bar dressing (angle adjustment grinding stone) to grind to the angle, it is inconvenient to use the grinding pin according to the grinding stone angle. In another method, the heat treatment pin is used to reduce the hardness of the heat treatment on the lathe and process it into a bite. This method also has low heat treatment hardness, making pins easy to wear and rough surfaces, making them unsuitable for heat treatment molds. In addition, the existing roller type step pin grinding jig is placed on the pin where two rollers are engaged and pushed with a bearing, then the roller is rotated by hand, but there is a flaw in which angle step cannot be processed without vibration due to vibration and flow. Technologists avoid the use at the site and use the old-fashioned grinding method using blocks that are inconvenient and injured due to lack of useful value.

In order to solve the above drawbacks, it was created in a completely different form from the existing products, and the pins are placed in the grooves of various sizes, large and small, on the grinding jig support plate composed of the main body, the movable body and the spring coupling pressing plate. After pressing, adjust the angle by turning the main body screw rod, and then rotate the pin while grinding the pin tightly against the length adjusting plate, and help to develop precise and cutting-edge parts that are miniaturized and require durability by grinding the exact angle and step dimension. The purpose is to provide an angle step pin grinding jig.
