Abstract
The utility model discloses an internal thread tapping device for a deep blind hole, which comprises a drill machine main shaft and a screw tap. The internal thread tapping device is characterized by including a connecting rod connected between the drill machine main shaft and the screw tap, a friction type tapping collet is mounted on the drill machine main shaft, an insertion hole for the plug-in connection of the screw tap is formed at the lower end of the connecting rod, a bolt for locking the screw tap is arranged on the side surface of the insertion hole, and the upper end of the connecting rod is fixedly connected with the friction type tapping collet. The arrangement of the connecting rod leads to increased working length of the screw tap, and the connection of the collet helps ensure the mechanically driven tapping. The device has the following advantages: the processing efficiency and the processing precision are greatly improved; the processing time for each screw hole is 30 seconds, one tenth of the time for manual tapping with the traditional screw tap with a standard length; and the work intensity of operators is greatly reduced. The internal thread tapping device can be widely applied in the thread processing for a compressor cylinder, a flywheel, a coupler and other parts.
Description
Technical field
The utility model relates to the thread tapping field of tool of machinery manufacturing industry, particularly a kind of degree of depth blind hole internal thread chasing bar.
Background technology
In the cylinder part design of high pressure compressor, the cylinder end face has one group of screw thread to be used for fixing cylinder head and water jacket, and its screw adopts blind threaded design, because its degree of depth is dark, lean on casing wall near, boring and tapping be difficulty relatively.The length of M30 die hob is less than the height of cylinder, in the top uropore that withstands on screw tap, clips screw tap side's tenon with spanner and carries out tapping by manual work during tapping, attacks half-turn, unloads lower ejector lever and attacks, bit by bit attacks, and accomplishes until tapping; Tapping time of each screw needs 5 minutes, and the labour intensity of this manual tapping is very big, and often six screws are done on workpiece, and the operative employee will grind bubble on hand.In addition, part such as flywheel, shaft coupling also has similar designing requirement.
The utility model content
The purpose of the utility model is to provide a kind of degree of depth blind hole internal thread chasing bar, is intended to solve the problem that existing standard length screw tap can't machining.
The purpose of the utility model is achieved through following technical scheme, and a kind of degree of depth blind hole internal thread chasing bar comprises drill press spindle and screw tap; It is characterized in that; Also comprise a connecting rod that is connected between drill press spindle and the screw tap, a chuck is installed on the said drill press spindle, the lower end of said connecting rod is provided with the jack that supplies said screw tap to peg graft; The side of said jack is provided with the bolt of locking screw tap, and the upper end of said connecting rod is fixedly connected with said chuck.
The further technical scheme of the utility model is that said chuck is the friction-type tap holder.
The utility model increases the active length of screw tap, through the connected mode of chuck through installing the mode of connecting rod additional; Guarantee the Mechanical Driven tapping; This device significantly improves working (machining) efficiency and machining accuracy, is 1/10th of the manual tapping of existing standard length screw tap 30 seconds process times of each screw; Significantly reduce operating personnel's working strength, can be widely used in the screw thread processing of parts such as compresser cylinder, flywheel, shaft coupling.

The specific embodiment
As shown in Figure 1, a kind of degree of depth blind hole internal thread chasing bar comprises drill press spindle 1, connecting rod 3 and screw tap 4; A chuck 2 is installed on the drill press spindle 1, and chuck 2 is selected the friction-type tap holder for use, and the upper end of connecting rod 3 is inserted in the chuck 2 and fixed; The jack 31 that supplies screw tap 4 to peg graft is offered in the lower end of connecting rod 3; Screw tap 4 is selected the M30 die hob for use, and the side of jack 31 is provided with the bolt 5 that is used to lock screw tap 4, and bolt 5 is selected the M8 bolt for use.
As shown in Figure 2, add man-hour, the workpiece 6 that at first will process is fixed on the frock 7, utilizes the Z3050 radial drilling machine to cooperate this device to carrying out mechanical tapping in the blind hole on the workpiece then, and machinable workpiece comprises compresser cylinder, flywheel, shaft coupling etc.
The foregoing description is merely a preferred embodiments of the utility model; The technical conceive and the essential implementation of the utility model have been specified; Be not to be that protection domain to the utility model limits; All any simple modification and equivalent structure transformation or modifications of being done according to the utility model spirit all should be encompassed within the protection domain of the utility model.
Claims (2)
1. degree of depth blind hole internal thread chasing bar; Comprise drill press spindle and screw tap, it is characterized in that, also comprise a connecting rod that is connected between drill press spindle and the screw tap; A chuck is installed on the said drill press spindle; The lower end of said connecting rod is provided with the jack that supplies said screw tap to peg graft, and the side of said jack is provided with the bolt of locking screw tap, and the upper end of said connecting rod is fixedly connected with said chuck.
2. a kind of degree of depth blind hole internal thread chasing bar according to claim 1 is characterized in that said chuck is the friction-type tap holder.
