Tibia outer side locking plate finish machining positioning and drilling device

Abstract

The invention discloses a tibia outer side locking plate finish machining positioning and drilling device. The device comprises a base, a workbench is fixed to the surface of the top end of the base,a mounting frame is fixed to a cavity of the base, a forward and reverse rotation motor is fixed to the inner side of the mounting frame, and an output shaft of the forward and reverse rotation motoris rotationally connected with a rotating shaft. The rotating shaft rotationally penetrates through the outer wall of the bottom end of the workbench, the rotating shaft extends to a cavity of the workbench, a third bevel gear is fixed to the tail end of the rotating shaft, and the two sides of the third bevel gear are in engaged connection with a first bevel gear and a second bevel gear correspondingly. Through the arrangement of the forward and reverse rotation motor, the distance between clamping mechanisms can be conveniently and rapidly adjusted, and the positioning effect of the clampingmechanisms on a locking steel plate is guaranteed; through the arrangement of fan blades, wind power generated when the fan blades rotate can cool the forward and reverse rotation motor in a workingstate; and through the arrangement of the fan blades, a drill bit can be conveniently and rapidly replaced, and the drilling effect of the drill bit on the locking steel plate is guaranteed.

Description

technical field [0001] The invention relates to the technical field of positioning drilling devices, in particular to a positioning drilling device for finishing the lateral tibial locking plate. Background technique [0002] Locking plate, is a fracture fixation device with locking threaded holes. The locking plate makes the combination of bone and plate stronger, making the amputated limb more stable after reduction. The positioning drilling device is needed in the processing and production of the locked steel plate; the positioning drilling device refers to the general name of the equipment used to process holes on solid materials. Common drilling devices include electric drills, drilling machines, etc. With further development, the efficiency of the drilling device has also been greatly improved. [0003] However, there are still some disadvantages in the existing tibial lateral locking plate finishing and positioning drilling device. When drilling the locking plate, t...

Problems solved by technology

[0003] However, there are still some disadvantages in the existing tibial lateral locking plate finishing and positioning drilling device. When drilling the locking plate, the distance between the second clamping plate and the first clamping plate cannot be adjusted according to the size of the locking plate. The problem of adjusting; in addition, when the reversing motor is working, it will generate a certain amount of heat, and there is a problem that it cannot dissipate heat. In addition, when the drill bit is used for a long time, the surface of the drill bit will be worn to varying degrees, which is inconvenient Disassembly problem, for which we propose a positioning drilling device for finishing the lateral tibial locking plate
