Description

Table type pneumatic tapping machine

Technical Field

The utility model relates to an equipment processing device, in particular to desk-top pneumatic tapping machine.

Background

The tapping machine is a machine tool for processing internal threads by using a screw tap, and is an internal thread processing machine tool which is most widely applied.

The pneumatic tapping machine is one of tapping machines, and the pneumatic tapping machine adopts the compressed air drive, utilizes less atmospheric pressure and tolerance can output great torsion, can be to materials tapping such as steel, iron, copper, aluminium and plastics, and the collet chuck is from taking overload device, and the tap damage is less, and the thread precision is high, easy operation. Most pneumatic tapping machines need a manual aperture of beating when using, and the material of required tapping is pressed to the hand, aims at the aperture and carries out the tapping, because most pneumatic tapping machines can not fix the material of required tapping, leads to the tapping machine to probably deviate the position of required tapping in the screw hole of tapping on the material, beats a aperture in advance and play the location, drills down along the aperture, avoids taking place the skew at the tapping process.

Therefore, the fixing device is provided for simply fixing the workpiece, thereby simplifying the processing steps.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a desk-top pneumatic tapping machine.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a desk-top pneumatic tapping machine, includes base, support and drill bit, be provided with the fixed station on the base, the fixed station surface is provided with the rubber pad, the rubber pad thinks from the central point and thickens gradually all around, the rubber pad minimum is provided with the through-hole that runs through its thickness, the fixed station extends with the position department of through-hole and forms the second through-hole, the through-hole extends to second through-hole department and is provided with the intubate.

Preferably, the device further comprises an air pump connected with the cannula.

Preferably, the rubber pad comprises an abutting plate and a rubber pad layer.

Preferably, the abutting plate is recessed from the periphery to the through hole, and the rubber cushion layer is horizontally arranged.

Preferably, the fixed platform and the base are arranged in parallel, and a tapping seam is formed between the fixed platform and the base.

Preferably, the rubber cushions are provided in four groups.

Preferably, a scraper is provided on a surface of the base facing the fixed base.

To sum up, the utility model discloses following beneficial effect has:

when the processing fixture is used, a plate to be processed is placed on the surface of the fixing table, then air is pumped from the insertion tube by the air pump, and a cavity between the rubber cushion layer and the butt plate is in a negative pressure state in the air pumping process, so that the processed plate is adsorbed and fixed; after the tapping, take off the air pump, leak tapping rubbish from the through-hole to the tapping seam again, recycle the scraper blade and strike off.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Example (b):

a desk-top pneumatic tapping machine, as shown in fig. 1, includes base 1, support 2 and drill bit 3, is provided with fixed station 4 on the base 1, and fixed station 4 surface is provided with rubber pad 41, and rubber pad 41 is the thickening gradually all around from the central point, and the rubber pad 41 the lowest point is provided with the through-hole 42 that runs through its thickness, and fixed station 4 extends with the position department of through-hole 42 and forms second through-hole 421, and through-hole 42 extends to second through-hole 421 punishment and is provided with intubate 422.

As shown in fig. 1, an air pump 43 connected to cannula 422 is also included.

As shown in fig. 1, the rubber pad 41 includes an abutting plate 411 and a rubber pad layer 412.

As shown in fig. 1 and 2, the abutting plate 411 is recessed from the periphery to the through hole 42, the rubber pad 412 is horizontally disposed, in this embodiment, the rubber pad 412 is square, and a through groove is cut along a diagonal line on the surface of the rubber pad 412, so that the rubber pad 412 is divided into four groups.

As shown in fig. 1, the fixing table 4 is disposed parallel to the base 1, and a tapping slit 11 is formed between the fixing table 4 and the base 1.

As shown in fig. 1, a scraper 12 is provided on a surface of the base 1 facing the fixed base 4, and the scraped waste is removed by the scraper 12.
