Description

Technical Field

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

[0002] During the drill bit production process, the manufacturer needs to put its own factory logo on the drill bit to indicate that the drill bit is produced by itself. 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, thereby completing 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 drill bit production process. However, in this way, the manufacturer does not have the corresponding supply freedom during 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 bits. Summary of the invention

[0007] As a further improvement of the present invention, the clamp disk includes a main disk, an auxiliary disk and a rotating shaft. The rotating shaft is rotatably arranged on the frame. The main disk and the auxiliary disk are coaxially sleeved on the rotating shaft.

The fixed frame is fixed at a position of the frame relative to the clamp disk at one end of the body rotation assembly, and the body of the motor can be translatedly arranged on the fixed frame to slide and connect or separate the head rotation seat with the drill head.

[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 3As shown, a drill bit laser marking machine of the present embodiment includes a frame 1, a drill bit positioning device 2 arranged on the frame 1, and a laser marking head 3 arranged above the drill bit positioning device 2. During marking, the drill bit is arranged in the drill bit positioning device 2, and the laser marking head 3 uses a laser to mark the mark on the drill bit in the drill bit positioning device 2. During the use of the drill bit laser marking machine of the present embodiment, the drill bit is first gradually transported to the drill bit positioning device 2 by an external feeding device. In the present embodiment, a ramp track transportation method is adopted, and the drill bit is gradually transported to the drill bit positioning device 2 by its own gravity, and then the drill bit is positioned by the drill bit positioning device 2, so that the laser marking head can mark the drill bit, thereby achieving an effect of marking on the drill bit. Therefore, compared with the extrusion marking method used in the prior art, it is not necessary to mark during the drill bit production process, and the marking can be performed after the drill bit production is completed, thereby avoiding the problem of high costs caused by redundant drill bits.

[0020] As an improved specific implementation method, the drill bit positioning device 2 includes a fixture disk 21, a rotating mechanism 22 and a marking rotating mechanism 23, and the rotating mechanism 22 and the marking rotating mechanism 23 are both arranged on the frame 1. The fixture disk 21 can be rotatably arranged below the laser marking head 3 and driven to rotate by the rotating mechanism 22. A groove 214 for embedding the drill bit is opened on its circumference, so that it is driven by the rotating mechanism 22 to rotate and convert the drill bit position below the laser marking head 3. The marking rotating mechanism 23 drives the drill bit to rotate for marking during marking. By using the setting of the groove 214 on the fixture disk 21, the positioning of the drill bit can be simply and effectively achieved. By setting 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. By setting the marking rotating mechanism 23, the drill bit can be driven to rotate during the marking process, so that the drill bit can achieve the effect of all-round marking.

The unloading lever 12 in this embodiment adopts a rotating shaft, and then uses a cylinder to promote the rotation of the rotating shaft to achieve the action. At the same time, the cylinder is connected to the controller to achieve synchronous action with the clamp disk 21. 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.

The lifting sleeve 2318 is retractable to shrink the column 2316 for positioning. Through the setting of the lifting sleeve 2318, the height of the head rotating seat 2313 can be adjusted by adjusting the height of the fixed plate 2314, so that the drill positioning device 2 can adapt to drills of different diameters, thereby effectively increasing the application range of the drill laser marking machine.

Through the setting of the driven seat 2323, it can effectively cooperate with the head rotating seat 2313 to achieve the connection with the drill bit by supporting the two ends of the drill bit, so that the head rotating seat 2313 can better rotate with the drill bit, and this connection method only requires the head rotating seat 2313 and the driven seat 2323 to contact with the drill bit, and does not need to form a nested structure, which increases the fault tolerance of the connection, so that the head rotating seat 2313 can better drive the drill bit to rotate.
