Bit upper ring device

The present invention provides a drill upper ring device, and more particularly a drill upper ring device for performing an upper ring on a straight path.

It is known that after a plurality of uses of the drill bit, the blade portion is liable to lose the drilling accuracy due to wear. In order to prolong the service life of the drill bit, a manufacturer has developed a drill grinding device, such as the Taiwan Patent Publication No. M444243, which discloses A plurality of clip drills are arranged radially on a turntable, and a feed zone, a feed detection zone, a grinding zone and a discharge detection zone are arranged in sequence around the turntable, and the clamp is clamped horizontally The drill bit is rotated by the turntable, and the drill bit is sequentially positioned in the feed zone, the feed detection zone, the grinding zone and the discharge detection zone to form a circulation loop, and a plurality of clamp drills arranged on the turntable, At the same time, the work is carried out in each work area to increase the work efficiency when the drill bit is operated.

When the drill bit is ground once, it is necessary to set the quasi-position ring, or the drill bit needs to re-adjust the position of the quasi-position ring after re-grinding. The traditional method is to manually perform the upper ring operation of the drill bit, thus causing the problem that the precision control is not easy. Developed, as disclosed in Taiwan Patent No. 448082, a precision automatic upper ring method for a drill bit for a PC board and a device thereof, which are provided with a feeding zone and a discharge zone on both sides of a processing turntable, and on the circumference of the turntable The drilling area, the push-drilling area, the upper ring area, the measuring area, the drilling area and the unloading area are respectively set up, and the continuous automatic process is replaced by the manual automatic process.

However, the above two are respectively rotary processing tools, and when the drill bit is to be sequentially ground and the upper ring is operated, it is necessary to pass through the above two Multiple work area stations cause too much time, which leads to a decrease in work efficiency. In this regard, it is generally difficult for a person skilled in the art to understand, but when the above-described cutting edge grinding device and the upper ring device are to be integrated, both of them are operated using a turntable, which causes difficulty in integration. Therefore, how to change the configuration of the work area station in the upper ring device so that the upper ring device can be integrated into the drill edge grinding device becomes a technical problem to be overcome.

In view of the above problems, the purpose of the present invention is to change the arrangement of the work area stations in the upper ring device so that the upper ring device can be integrated into the edge grinding device. Specifically, the technical means of the novel upper ring device includes a drill bit, and a positioning ring is disposed on the drill shoe, and the drill sliding seat is intermittently along a straight path on a machine table. Sliding and stopping; a pick-up point is located in the straight path, the drill slide can stop at the pick-up point; an upper loop point is located in the straight path and is located at the take-off point On one side, the drill slide can be stopped at the upper ring point, and the top and bottom of the upper ring point are oppositely disposed with a pressure ring rod and a push rod rod, and the pressure ring rod is pressed against the positioning slide ring The push pin pushes the drill bit upward; and a push drill point is located in the straight path, and between the take-up point and the upper ring point, the drill slide can stop at the push drill point, The push point is configured with a pin bar that pushes the bit down.

Accordingly, the novel upper ring device is a method of arranging a work station on a straight path instead of the conventional arrangement of the work station on the arc path, so that the upper ring device can be integrated into the drill grinding device to lift the drill. The working efficiency of the blade grinding device.

In a further implementation, the push pin is guided by a ball lead screw and driven by a driver to push the drill bit upward, wherein the push pin receives the guide of the ball lead screw via a sleeve So that the pusher bar can be moved upward by the drive. Accordingly, the ball lead screw is used to control the displacement amount of the push pin to push the bit upward, so as to accurately adjust the distance between the bottom of the level ring and the edge of the drill bit, thereby controlling the drill bit to be drilled. The depth of the hole.

In a further implementation, the needle bar is urged to move downward by a first pneumatic actuator. Accordingly, it is advantageous to adjust the position of the quasi-position ring on the drill bit.

In a further implementation, the pressure ring lever is pressed by a second air pressure driver to press the level ring on the drill shoe. Accordingly, when the push pin is pushed to move the bit upward, the position ring can be prevented from following the movement to adjust the distance between the bottom of the level ring and the edge of the drill bit.

In a further implementation, a grinder is further disposed on the adjacent side of the pick-up point, and the drill bit is moved by the grinder and then moved toward the position of the pick-up point by the rotation of a turntable. Accordingly, the drill is driven by the turntable to perform the upper ring work after the grinding.

In a further implementation, a charge coupled component is disposed between the grinder and the pick-up point, the charge-coupled component taking an image of the edge of the drill bit. Accordingly, the polishing quality of the drill blade portion is detected by the charge coupled device.

In a further implementation, the turntable is provided with at least one gripper, the gripper holding bit is positioned on the turntable, and the turntable drives the drill bit to intermittently move and stop in an arc machining path, wherein the grinder The charge coupled components are respectively located in the arc machining path. Accordingly, after the chuck is gripped, the gripper passes through the grinder and passes through the grinder and the charge coupled component.

In a further implementation, a mover is disposed between the turntable and the pick-up point, the gripper picking up the drill bit on the turntable and inserting it into the drill-slide slide at the pick-up point. Accordingly, the drill bit is inserted into the drill-sliding carriage by the gripper to perform the upper ring work of the drill bit.

The above content and the subsequent embodiments and the drawings are briefly described in order to further explain the technical means adopted by the present invention to solve the problem and the effects thereof. The relevant details of the present invention that can be implemented will also be explained in the subsequent detailed description and drawings.
