Abstract
A turning type drill jig comprises a body. A positioning supporting boss is arranged on one side of the body, a hole is arranged at the center of the positioning supporting boss, an auxiliary positioning support is mounted in the hole, the top of the auxiliary positioning support is provided with a platform face, a locking nut is mounted on a lower portion of the positioning support, a bolt hole is arranged on the body close to the positioning supporting boss, and a positioning pin is mounted on the bolt hole. The turning type drill jig is used on a vertical type drilling machine and can be used for processing reaming and end face of the reaming on a lever arm, in order to prevent deformation of workpieces during processing, the auxiliary positioning support is adopted, and when the auxiliary positioning support contacts with the workpieces, the workpieces are locked by the nut. When drilling of one hole of the lever arm is finished, another hole is drilled by turning the turning type drill jig. The turning type drill jig is suitable for large-scale production.
Description
Technical field
The utility model relates to the auxiliary clamp that uses in the drilling machine process.
Background technology
Drilling machine need to carry out twice the location when the fraising of processing lever arm, and because lever arm itself is not axially symmetric structure, all can produce certain error in the time of twice location, particularly whether twice locating shaft be identical, whether the fraising of processing is parallel to each other, and all can affect the precision of the rear part of processing.
The utility model content
The purpose of this utility model provides a kind of positioning fixture of secondary process lever arm.
The technical solution adopted in the utility model is:
Convertible drill jig, comprise body, be provided with the positioning supports boss in a side of body, at the center drilling of positioning supports boss and auxiliary positioning is installed supports, the top that described auxiliary positioning supports has flat surface, in the bottom of described positioning supports locking nut is installed; Near described positioning supports boss body has bolt hole, at bolt hole alignment pin is installed.
The external diameter of described alignment pin equals the internal diameter of lever arm centre bore to be processed.
Be provided with the adjustable supporting nail at described body rear wall, the upper side of the flat surface that described adjustable supporting nail and described auxiliary positioning support.
These anchor clamps use on upright drill, can be used for fraising and end face thereof on the processing lever arm, add the distortion in man-hour for preventing workpiece, have adopted the auxiliary positioning support, when auxiliary positioning supports with after workpiece contacts, use nut check.
When having bored a hole of lever arm, come drilling another one hole in upset.These anchor clamps are fit to popular production in batches.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the front view of the described convertible drill jig of the utility model embodiment.
Fig. 2 is the top view of the described convertible drill jig of the utility model embodiment.
Fig. 3 is the side view of the described convertible drill jig of the utility model embodiment.
The specific embodiment
As Figure 1-3, the described convertible drill jig of the utility model embodiment, comprise body 1, side at body 1 is provided with positioning supports boss 2, at the center drilling of positioning supports boss 2 and auxiliary positioning is installed supports 3, the top of described auxiliary positioning support 3 has flat surface, in the bottom of described positioning supports 3 locking nut 4 is installed; Near described positioning supports boss 2 body has bolt hole, at bolt hole alignment pin 5 is installed.
The external diameter of described alignment pin 5 equals the internal diameter of lever arm 6 centre bores to be processed.
Be provided with adjustable supporting nail 7 at described body 1 rear wall, the upper side of the flat surface of described adjustable supporting nail 7 and described auxiliary positioning support 3.
These anchor clamps use on upright drill, can be used for fraising and end face thereof on the processing lever arm, add the distortion in man-hour for preventing workpiece, have adopted the auxiliary positioning support, when auxiliary positioning supports with after workpiece contacts, use nut check.
When having bored a hole of lever arm, come drilling another one hole in upset.These anchor clamps are fit to popular production in batches.
