Abstract

The utility model relates to the technical field of machines, in particular to an angle ruler board for a lathe drilling tool of a V-shaped three-way joint. The angle ruler board for the lathe drilling tool of the V-shaped three-way joint comprises an angle ruler board body and is characterized in that a circular-truncated-cone-shaped groove is formed in the lower side of the center of the angle ruler board body and the bottom of the circle center of the circular-truncated-cone-shaped groove is provided with a through hole in a connected mode; four threaded holes are evenly formed in the periphery of the outer edge of the circular-truncated-cone-shaped groove; two sunk screw holes are respectively formed in the left side and the right side on the lower portion of the circular-truncated-cone-shaped groove, and a pin hole is formed between every two corresponding sunk screw holes. Compared with the prior art, the lathe positioning angle ruler board special for drilling of the V-shaped three-way joint is provided and the angle ruler board is matched with a bottom board, so that the V-shaped three-way joint is better fixedly clamped, difficulty of following drilling operation is reduced, the rejection rate of V-shaped three-way joints is reduced, and production efficiency is improved.

Description

A kind of angle square board of V-type threeway lathe boring frock
Technical field
The utility model relates to field of mechanical technique, specifically a kind of angle square board of V-type threeway lathe boring frock.
Background technology
Because the such parts of V-type threeway are not conventional parts, and the quantity of demand is few, therefore the processing for V-type threeway all positions processing in addition by hand by workman, and the boring of V-type threeway is operated in and is difficult on common lathe to realize, needing special location-plate to position clamping could hole, and does not have stationary device to process, locate, and this strengthens the difficulty of processing, be easy to cause the defective of product, cause scrapping.
Summary of the invention
The utility model is for overcoming the deficiencies in the prior art, providing special is the boring lathe positioning angle square plate of V-type threeway, angle square board matches with base plate, better V-type threeway is fixed to clamp, follow-up boring work has been reduced to difficulty, and the scrappage that has reduced V-type threeway, has improved production efficiency.
For achieving the above object, design a kind of angle square board of V-type threeway lathe boring frock, comprise angle square board body, it is characterized in that: the central downside that is positioned at angle square board body is provided with truncated cone-shaped groove, the bottom, the center of circle of truncated cone-shaped groove is connected with through hole; The outer rim surrounding that is positioned at truncated cone-shaped groove is laid with 4 screwed holes; The left and right sides that is positioned at truncated cone-shaped groove below is respectively equipped with 2 sunk screw holes, between 2 sunk screw holes, is provided with pin-and-hole.
A side that is positioned at the screwed hole of truncated cone-shaped groove top is provided with circular groove, and the center of circle of the screwed hole of the center of circle of circular groove and truncated cone-shaped groove top is positioned on same circumference.
Angle between the center of circle of screwed hole of the line in the center of circle of the center of circle of described circular groove and truncated cone-shaped groove and truncated cone-shaped groove top and the line in the center of circle of truncated cone-shaped groove is 30 °.
The left and right sides, top of described angle square board body is respectively equipped with another screwed hole.
The left and right sides, below of described angle square board body is respectively equipped with another sunk screw hole.
Compared with the existing technology, provide special is the boring lathe positioning angle square plate of V-type threeway to the utility model, and angle square board matches with base plate, better V-type threeway is fixed to clamp, follow-up boring work has been reduced to difficulty, and reduced the scrappage of V-type threeway, improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 be in Fig. 1 A-A to cutaway view.
Referring to Fig. 1, Fig. 2,1 is angle square board body, and 2 is circular groove, and 3 is screwed hole, and 4 is truncated cone-shaped groove, and 5 is through hole, and 6 is pin-and-hole, and 7 is sunk screw hole, and 8 is another sunk screw hole, and 9 is another screwed hole.
The specific embodiment
With reference to the accompanying drawings the utility model is described further below.
As Fig. 1, shown in Fig. 2, the central downside that is positioned at angle square board body 1 is provided with truncated cone-shaped groove 4, and the bottom, the center of circle of truncated cone-shaped groove 4 is connected with through hole 5; The outer rim surrounding that is positioned at truncated cone-shaped groove 4 is laid with 4 screwed holes 3; The left and right sides that is positioned at truncated cone-shaped groove 4 belows is respectively equipped with between sunk screw hole 7,7,2,2 sunk screw holes and is provided with pin-and-hole 6.
A side that is positioned at the screwed hole 3 of truncated cone-shaped groove 4 tops is provided with circular groove 2, and the center of circle of the screwed hole 3 of the center of circle of circular groove 2 and truncated cone-shaped groove 4 tops is positioned on same circumference.
Angle between the line in the center of circle of the screwed hole 3 of the line in the center of circle of the center of circle of circular groove 2 and truncated cone-shaped groove 4 and truncated cone-shaped groove 4 tops and the center of circle of truncated cone-shaped groove 4 is 30 °.
The left and right sides, top of angle square board body 1 is respectively equipped with another screwed hole 9.
The left and right sides, below of angle square board body 1 is respectively equipped with another sunk screw hole 8.
V-type threeway is fixed on base plate by fixture, and the rear side of base plate is fixed by angle square board body 1, so just V-type threeway better can be fixedly clamped, and facilitates follow-up boring work.
Providing special is the boring lathe positioning angle square plate of V-type threeway, and angle square board matches with base plate, better V-type threeway is fixed to clamp, and follow-up boring work has been reduced to difficulty, and has reduced the scrappage of V-type threeway, has improved production efficiency.
