Description

Technical Field

[0001] The invention relates to a positioning device, and more particularly to a laser marking drill bit positioning device. Background Art

[0002] During the production process of drill bits, manufacturers need to put their own factory logo on the drill bits to indicate that the drill bits are produced by themselves. Since the drill bits are all produced by integrated forging, the existing marking method is to use a marking head to forcibly squeeze it onto the drill bit, thereby forming a groove on the drill bit that is the same as the logo, so as to complete the marking on the drill bit. However, if the above marking process is performed after the drill bit is completed, it is easy to cause the drill bit to deform, making the drill bit unusable. Therefore, in the prior art, the logo is directly stamped onto the drill bit during the production process of the drill bit. However, in this way, the manufacturer does not have the corresponding supply freedom in the supply process. When there is a change in order, it often leads to the problem that the excess marked drill bits cannot be sold, which increases the production cost of the drill bit. In the direct laser marking method, the existing laser marking workbench is a platform structure, and the existing drill bit is cylindrical as a whole, so it cannot be directly placed on the workbench for laser marking, and workers are required to mark by hand, which greatly reduces the efficiency of laser marking of the drill bit.

[0018] The present invention will be further described below in conjunction with the embodiments given in the accompanying drawings, wherein the drill head and body involved in this embodiment are: the part where the drill bit is connected to the external device is the head, and the part where the drill bit drills into the external object is the body.

[0019] Reference Figures 1 to 3 As shown, a laser marking drill bit positioning device of the present embodiment includes a fixture disk 21 and a rotating mechanism 22. The rotating mechanism 22 is arranged on the frame of the laser marking machine. The fixture disk 21 can be rotatably arranged under the laser marking head and is driven to rotate by the rotating mechanism 22. A groove 214 for embedding the drill bit is opened on its circumference, so that it can be driven by the rotating mechanism 22 to rotate and convert the drill bit position under the laser marking head. The marking rotating mechanism 23 drives the drill bit to rotate during marking. The setting of the embedding groove 214 on the fixture disk 21 can simply and effectively realize the positioning of the drill bit. Through the setting of the rotating mechanism 22 and the marking rotating mechanism 23, different drill bits can be replaced to the bottom of the laser marking head by rotating the fixture disk 21, thereby realizing the laser marking position conversion.

[0020] As an improved specific implementation method, the rotating mechanism 22 includes a rotating motor 221 and a gear box 222. The rotating shaft of the rotating motor 221 is connected to the input shaft of the gear box 222. The gear box 222 has a first output shaft and a second output shaft. The first output shaft and the fixture disk 21 are linked by a belt. A feed port 11 is provided on the external frame near the fixture disk 21. A feed port 11 is provided with a flippable feed lever 12 on the edge of the feed port 11.

A fixed sleeve is provided on the second output shaft. There is a counting disk 2222, and the second output shaft rotates with the counting disk 2222 to pass through the counting sensor 2221, so that the counting sensor 2221 senses the count. Through the setting of the gear box 222, it is possible to use a rotating motor 221 to drive the clamp disk 21, and the drill bit can be simply and effectively pushed off the clamp disk 21 by flipping the unloading lever 12. In this way, the overall marking efficiency can be increased by increasing the rotation speed of the rotating motor 221. Through the setting of the counting sensor 2221 and the counting disk 2222, the drill bits completed in the marking process can be counted, which is convenient for the subsequent supply situation and further avoids the problem of waste caused by excessive production of drill bits.

[0021] As an improved specific implementation method, the lower end of the unloading rod 12 is fixedly connected with a rotating shaft, and the end of the rotating shaft away from the unloading rod 12 is sleeved with a long swing block, and a unloading cylinder is provided under the clamp disk 21, and the push rod of the unloading cylinder is hinged to the end of the swing block facing away from the rotating shaft to promote the rotation of the rotating shaft, thereby driving the unloading rod 12 to flip. The unloading rod 12 in this embodiment adopts a method of setting a rotating shaft and then using a cylinder to push the rotating shaft to rotate to achieve the action. At the same time, the cylinder is connected to the controller to achieve synchronous action with the clamp disk 21, so that the action of the unloading rod 12 and the rotation of the clamp disk 21 can be effectively coordinated, thereby effectively improving the marking and discharge speed of the drill bit.

In this way, double-part positioning of the drill bit can be achieved, which increases the stability of the drill bit during the marking process and enables the laser marking head to better mark the drill bit.

[0023] As an improved specific implementation method, magnets are provided at the bottom of the head groove 2141 and the body groove 2142 to attract the head and body of the drill bit. Through the setting of the magnets, the drill bit can be effectively positioned by adsorption, and after positioning, the drill bit can still rotate.

The overall structure is simple and easy to implement. In addition, the setting of the slide rail 2317 can ensure that the translation plate 2315 is translated along the axis of the clamp disk 21 during the translation process, so it can also ensure that the translation of the head rotating seat 2313 is also translated along the axis of the clamp disk 21, so that the head rotating seat 2313 can be better connected or separated from the head of the drill bit.
