Description

Drilling tool for four-way pipe
Technical Field
The utility model relates to the field of pipe fitting machining tools, in particular to a drilling tool for a four-way pipe.
Background
As is well known, the mold and the tool are widely used in the machining technology and manufacturing field, and the mold and the tool are processed to play the most important role in the manufacturing process of four-way drilling. Once the four-way drill is not well manufactured, the four-way drill becomes waste, the position degree required in the four-way drill machining is +/-0.05 mm, the four-way drill cannot be out of tolerance, the precision requirement cannot be guaranteed by a common machining method, the four-way drill is different each time, and in addition, the drill is not easy to position on the cambered surface.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides the drilling tool for the four-way pipe, which can ensure the machining precision requirement and ensure the same quality of each machining.
The technical scheme adopted for solving the technical problems is as follows: a drilling tool for a four-way pipe is provided with a clamping jig and is characterized in that two V-shaped cushion blocks are longitudinally and parallelly fixed at the front end and the rear end of the middle part of the upper surface of the clamping jig respectively, a backing plate with the same height is transversely fixed at the left end and the right end of the middle part of the upper surface of the clamping jig respectively, the axes of the two backing plates and the transverse central line of the clamping jig deviate backwards by an angle, a cylindrical pin is vertically arranged at the four corner positions of the upper surface of the clamping jig respectively, the cylindrical pin is fixed through hexagonal nuts on the back of the clamping jig, the circular arc surfaces of the cylindrical pins are tangent to the front long side and the rear long side of the clamping jig respectively, pressing plates are fixed on the left side and the right side of the rear part of the upper surface of the clamping jig respectively through supporting screws, strip-shaped limiting grooves are machined on the pressing plates, the lower ends of inner hexagonal cylindrical bolts penetrate through the limiting grooves of the pressing plates and are rotatably arranged in the pressing screw holes of the clamping jig, the end face drilling templates are fixed on the outer sides of the corresponding two V-shaped cushion blocks through inner hexagonal bolts, and the middle parts of the end face drilling templates are uniformly distributed in a circular arrangement mode at intervals.
The four-way pipe processing device has the advantages of being convenient to operate, reducing the requirement on operators, being capable of being used for multiple times, being high in utilization rate, improving the processing speed, guaranteeing the positioning accuracy and quality of workpieces, and being capable of realizing batch processing production of the four-way pipe.
Drawings
The utility model will be further described with reference to the drawings and examples.
Fig. 1 is a schematic diagram of the structure of the present utility model, and is also a perspective view.
Fig. 2 is a top view of the present utility model.
Fig. 3 is a top perspective view of the present utility model.
