Abstract
The utility model provides a tapping device. The tapping device comprises a fixing device and a rotating device, wherein the fixing device comprises a horizontal plate, a vertical plate, a first fixing block, a second fixing block and a third fixing block; the horizontal plate is fixed on a workbench; the vertical plate is perpendicularly arranged in the middle of the horizontal plate; the first fixing block, the second fixing block and the third fixing block are arranged on the right side of the horizontal plate; a track is arranged at the connecting part of the horizontal plate and the third fixing block; the rotating device comprises a rotating disk and gears; a rotating handle is arranged on the rotating disk; the rotating disk is connected with a first gear; a third gear penetrates through the vertical plate, and is connected with the fixing device; a tapping head is arranged at the front end of the fixing device. The tapping device has the benefits that when the conventional tapping device is adopted for workpiece tapping, a worker can control the third fixing block to move on a sliding track as required, and can easily control the tapping speed; the gears with gradually decreasing radiuses are adopted to drive the tapping head to rotate, labor of the worker can be relieved, and the effect of getting twofold results with half the effort is improved.
Description
Technical field
The utility model belongs to field of machining, especially relates to a kind of chasing bar.
Background technology
In existing threading apparatus, there are tap wrench, electric threading and hand tapping, tap wrench can for some workpiece of bulk processing, but for accuracy, require slightly higher often because of location, forbidden to cause defect ware and increase, although electric threading machine accuracy is high, its price is more expensive again, hand tapping is for different workpiece, be divided into again transversary with vertical structure, for the chasing bar of transversary, deposit again in use problem of effort.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, simple to operate, chasing bar that price is lower, is especially applicable to the workpiece of the horizontal tapping of needs.
The technical solution of the utility model is: a kind of chasing bar, comprise fixture and tumbler, fixture comprises level board, vertical plate, the first fixed block, the second fixed block and the 3rd fixed block, level board is fixed on workbench, vertical plate is vertical at the centre of level board, is provided with the first fixed block, the second fixed block and the 3rd fixed block on the right side of level board, level board is provided with track with the position that the 3rd fixed block is connected, tumbler comprises rotating disc and gear, rotating disc is provided with rotating handles, rotating disc is connected with the first gear, the first gear is fixed on vertical plate through vertical plate, the second gear is meshed and is connected with the first gear, the second gear is fixed on vertical plate through vertical plate, the 3rd gear is meshed and is connected with the second gear, the 3rd gear is connected with fixture through vertical plate, the front end of fixture is provided with tapping-head, the diameter of described the first gear is greater than the second gear, the diameter of described the second gear is greater than the second gear.
Further, to be fixed on the mode on vertical plate be that bolt and nut is fixed for described the first gear and the second gear.
Further, described fixture is the buckle structure of clamping, comprises the ring of two semicircles, and semicircular ring one end is fixed by connecting axle, and the other end is fixed by buckle and draw-in groove.
Advantage and the good effect that the utlity model has are: while using existing threading apparatus to carry out tapping to workpiece, workman can control the 3rd movement of fixed block on slideway as required, easily controls the speed of tapping; The gear driven tapping-head being reduced gradually by radius, rotational alleviates exerting oneself of workman, reaches power half merit effect doubly.
