The blade is usually made of pure titanium, titanium alloy, stainless steel or carbon steel and is generally disposable, while the handle can be reused. The assembly of medical cutting heads is a high-precision assembly; glue is applied before assembly and the blades are baked in an oven after assembly.

[0003] In the existing technology, the assembly of the cutter head is mostly done by simple observation and squeezing, which is inconvenient and the accuracy of the assembly is not good, thus affecting the assembly effect of the cutter head. Utility Model Content

[0004] The purpose of this utility model is to provide a high-precision assembly mechanism for a cutting head robot, so as to solve the problem mentioned in the background art that the assembly of cutting heads is mostly done by simple observation and squeezing, which is inconvenient and has poor accuracy, thus affecting the assembly effect of the cutting head.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a positioning cylinder, one side of the moving end of the positioning cylinder being fixedly connected to one side of a fixed frame; a vacuum generating assembly is provided on the top of the fixed frame, the vacuum generating assembly including a vacuum generator, a connecting pipe, and a vacuum suction cup; one side of the fixed frame is fixedly connected to one side of a pressing cylinder; a pre-pressing mechanism is provided on the moving end of the pressing cylinder, the pre-pressing mechanism including a pre-pressing plate, a limiting rod, a first magnet, a second magnet, a connecting rod, and a rubber sheet; and a detection mechanism is provided on one side of the fixed frame, the detection mechanism including a protective shell, a detection guide camera, and a light source.

[0006] In a preferred embodiment, the top of the mounting bracket is fixedly connected to the bottom of the vacuum generator, the air inlet of the vacuum generator is fixedly connected to the top of the connecting pipe, and the bottom of the connecting pipe is fixedly connected to the top of the vacuum suction cup.

[0007] In a preferred embodiment, the movable end of the pressing cylinder is fixedly connected to one side of the pre-pressing plate, and the top of the pre-pressing plate is fixedly connected to the bottom of the limiting rod.

[0008] In a preferred embodiment, the top of the limiting rod is fixedly connected to the inner wall of the fixing frame, and the bottom of the pre-pressing plate is provided with an installation port, the inner wall of which is fixedly connected to the top of the first magnet.

[0009] In a preferred embodiment, the bottom of the first magnet is movably connected to the top of the second magnet, and the bottom of the second magnet is fixedly connected to the top of the connecting rod.

[0010] In a preferred embodiment, the bottom of the connecting rod is fixedly connected to the top of the rubber sheet, and the bottom of the connecting tube extends to the bottom of the pre-pressure plate.

[0011] In a preferred embodiment, the limiting rod consists of a hollow sleeve and a fixing rod, and the top of the fixing rod is fixedly connected to the inner wall of the fixing frame.

[0012] In a preferred embodiment, one side of the mounting bracket is fixedly connected to one side of the protective shell, and the inner wall of the protective shell is fixedly connected to the outer wall of the detection and guidance camera, and the bottom of the protective shell is fixedly connected to the top of the light source.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model involves illuminating the bottom with a light source, detecting the position using a detection and guidance camera, and then moving the fixing frame to the top of the cutter head by activating a positioning cylinder. A pneumatic pressing cylinder then drives a pre-pressure plate to initially compress the cutter head via a limiting rod. Simultaneously, the bottom of a rubber sheet contacts the cutter head. Once the cutter head has been initially compressed, a vacuum generator is activated to adsorb and stabilize the cutter head through a connecting pipe and a vacuum suction cup. The positioning and pushing action of the detection and guidance camera's positioning cylinder, along with the downward compression of the pressing cylinder, facilitates the assembly of the cutter head and increases the accuracy during assembly.

[0015] 2. In this utility model, when the rubber sheet needs to be replaced, the rubber sheet can be directly removed, so that the connecting rod is away from the inside of the pre-pressure plate. At the same time, the second magnet and the first magnet are separated. The new rubber sheet is placed at the bottom of the pre-pressure plate through the connecting rod. The first magnet and the second magnet come into contact with each other, thereby stabilizing the rubber sheet. The rubber sheet increases the stability of the cutter head during pre-pressure and facilitates the replacement of the rubber sheet. Attached Figure Description
