Description

Vertical type roll end surface hole drilling tool

Technical Field

The utility model relates to a rectilinear roll end face hole drilling frock.

Background

In the roll production process, the end surface hole of the roll shaft is used for center correction in the subsequent machining of the roll. The existing processing of the end surface hole of the roll shaft is generally realized by flatly placing the roll on a workbench and boring the roll through a boring machine, and the conventional punching mode has the advantages of lower working efficiency, higher processing cost of the boring machine, easy deflection of the processed end surface hole and difficult hole position correction during processing.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides a can improve roll end face machining precision, improve work efficiency's rectilinear roll end face drilling frock.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a rectilinear roll end face hole drilling frock, has the bottom plate that can link firmly with the rocking arm drill workstation side, the bottom plate lower extreme install fixed V-arrangement piece, the bottom plate upper end is equipped with the removal V-arrangement piece that can control adjusting position, two parallel guide ways are seted up to the bottom plate upper end, remove the V-arrangement piece and establish on the guide way, be equipped with the guide pin between guide way and the removal V-arrangement piece bottom surface.

Specifically speaking, the bottom surface of the movable V-shaped block and the guide groove are provided with four guide pins which are distributed in a rectangular mode, a groove is formed in the middle of the movable V-shaped block, a locking bolt which is used for fixing the movable V-shaped block and the bottom plate after the movable V-shaped block is adjusted in place is arranged between the groove and the bottom plate, and a nut connected with the locking bolt is located in the groove.

In order to facilitate the firm connection, four mounting holes are formed in the bottom plate and are distributed in a rectangular shape.

The utility model has the advantages that: the utility model discloses an arrange the roll perpendicularly in between removing V-arrangement piece and the fixed V-arrangement piece, adjust through removing the V-arrangement piece and guarantee the roll straightness requirement that hangs down, adopt the rocking arm to bore the completion to the drilling in roll end face hole to be favorable to ensureing the perpendicular of roll end face hole, prevent the askew phenomenon of inclining, the correction of roll centre bore is added in convenient follow-up man-hour, improves work efficiency.

FIG. 3 is a schematic sectional view of B-B in FIG. 1.

In the figure: 1. the device comprises a base plate, 2 parts of a fixed V-shaped block, 3 parts of a movable V-shaped block, 4 parts of a guide groove, 5 parts of a guide pin, 6 parts of a groove, 7 parts of a locking bolt, 8 parts of a nut and 9 parts of a mounting hole.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The vertical roller end surface hole drilling tool shown in fig. 1-3 comprises a bottom plate 1 which can be fixedly connected with the side surface of a rocker arm drill workbench, and four mounting holes 9 which are distributed in a rectangular shape are formed in the bottom plate 1.

The lower end of the bottom plate 1 is provided with a fixed V-shaped block 2, the upper end of the bottom plate 1 is provided with a movable V-shaped block 3 which can be adjusted left and right, the upper end of the bottom plate 1 is provided with two parallel guide grooves 4, the movable V-shaped block 3 is arranged on the guide grooves 4,

the bottom surface of the movable V-shaped block 3 and the guide grooves 4 are provided with four guide pins 5 which are distributed in a rectangular shape, two guide pins 5 are arranged in each guide groove 4 and are respectively positioned at the left end and the right end of the movable V-shaped block 3, and the guide pins 5 are clamped into pin holes in the bottom surface of the movable V-shaped block 3.

A groove 6 is formed in the middle of the movable V-shaped block 3, a locking bolt 7 which is used for fixing the movable V-shaped block 3 and the bottom plate 1 after the movable V-shaped block 3 is adjusted in place is arranged between the groove 6 and the bottom plate 1, and a nut 8 connected with the locking bolt 7 is arranged in the groove 6.

During drilling, fix the bottom plate in the rocking arm drill workstation side through the mounting hole, the roll is arranged in perpendicularly and is removed between V-arrangement piece 3 and the fixed V-arrangement piece 2, and the one end that the roll needs to drill up, and the roll bottom can be arranged in subaerially, or sets up the parallels on ground and support the roll bottom, removes about removing V-arrangement piece 3 through removing, adjusts the roll straightness that hangs down, and it is fixed to remove V-arrangement piece 3 through locking bolt 7 and nut 8 after adjusting, adopts the rocking arm to bore the completion to roll end face hole.

Generally speaking, because roll dead weight reason, the roll need not to compress tightly during the drilling, but for guaranteeing that the drilling is stable, prevents that the roll accident from falling down, also can select a clamp plate for use, links firmly the clamp plate with the bottom plate through housing bolt and compresses tightly the roll.

The utility model discloses an arrange the roll perpendicularly in and remove between V-arrangement piece 3 and the fixed V-arrangement piece 2, adjust through removing V-arrangement piece 3 and guarantee the roll straightness requirement that hangs down, adopt the rocking arm to bore the drilling of accomplishing to roll end face hole to be favorable to ensureing the perpendicular of roll end face hole, prevent the askew phenomenon of inclining, make things convenient for the follow-up correction of adding man-hour roll centre bore, improve work efficiency.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
