An intelligent punching device

Abstract

The invention discloses an intelligent punching device, which comprises a framework, wherein a rotating mechanism, two or more than two cutting modules and a controller are arranged on the framework; the rotating mechanism is provided with a rotating tray; the two or more than two cutting modules are arranged on the rotating tray along the circumferential direction; each cutting module comprises a cutter blade, an ascending and descending motor and a pressure sensor; the ascending and descending motor is used for driving the cutter blade to ascend and descend; the pressure sensor is arranged between the cutter blade and the ascending and descending motor and is used for detecting the cutter blade pressure; the controller is used for receiving the pressure signal of the pressure sensor, and simultaneously controls the ascending and descending motor and the rotating mechanism according to the pressure signal. The intelligent punching device has the advantages that the structure is simple; the manufacturing cost of the device is low; the operation is convenient; the intelligent integration degree is high; on the premise of not destroying a target external structure, the hole manufacturing is automatically completed according to the design requirements; in addition, the hole size is adjustable.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to an intelligent punching device for animal thin-walled bones, skulls and the like. Background technique [0002] In major universities or scientific research institutions, all scientific researchers engaged in the field of biological materials, in order to verify the superiority of the materials and prove their good regenerative repair performance, need to conduct in vivo experiments on the materials, that is, put the manufactured materials into animals. In the body, after a long period of cultivation, the material is taken out, and the performance of the material is verified through a series of testing techniques. Before that, it is necessary to artificially create a defect in the animal body, and then put the material in, and the skull defect is repaired. The experiment is a very common experiment used to verify the performance of materials. U...

Problems solved by technology

[0003] At present, the machine used to open the hole is usually a hand-held grinder. The upper head is replaced with a ring drill, and then the operator holds the grinder at the designated position, and the foot switch controls the rotation of the grinder. Control the grinding head to move to the inside of the skull to drill holes. In this process, the size of the hole is controlled by the size of the ring drill, and the depth of the hole is the thickness of the skull wall. The thickness of the skull wall of each animal is different. For the operator, he can only slowly control the movement of the grinding head, first move it according to the predetermined distance to see if the skull can be taken out, if not, then move a certain distance, and then wait until the skull is taken out, this process is time-consuming It is laborious, and the drilling efficiency is very low. If the moving speed is too fast, the drill bit will penetrate the skull wall, and the end of the drill bit will directly damage the dura mater, and even the brain tissue of the animal. The most common is to destroy the blood vessels in the brain, causing massive bleeding , the animal loses too much blood and dies, even if the bleeding is stopped sometimes, the blood vessels in the brain will be blocked, causing the rabbit to die directly, or the animal is paralyzed by destroying the brain tissue, and the animal will die after a short time, etc., and the animal The skull is not in a regular shape, and its wall thickness is different on the same animal, but the end face of the drill bit is flat, and when the hole is drilled, there will be a place with a thin wall. When the depth of the drill is just right, other thick places will be insufficient. It is impossible to remove the skull, and it needs to be drilled again. At this time, the original thin wall will be too deep, destroying the dura mater and brain tissue. Mortality, but for novices, the mortality rate of animals is very high at the beginning, drilling depends largely on the operator's skills, which is very unfavorable for the promotion and use of the machine, a good machine should be No matter who operates it, the same effect can be achieved, more depends on the machine itself
