Abstract
The utility model discloses a fixture for a deflection instrument. The fixture comprises a stepped shaft, wherein the stepped shaft comprises a shaft a, a shaft shoulder and a shaft b, the shaft a and the shaft b are positioned at both ends of the stepped shaft, a positioning hole is respectively arranged on the end faces of the shaft a and the shaft b and is coaxial with the stepped shaft, and a three-jaw chuck is fixed on the shaft b. The utility model provides a special fixture used on a deflection instrument. In this way, radial runout detection can be carried out on workpieces with larger shaft holes, such as a flywheel and the like, by using a common deflection instrument, and the diameter of the three-jaw chuck is adjustable, so that the application range of the utility model is enhanced, and the universality is stronger.
Description
Technical field
The utility model relates to the engine detection range, especially relates to a kind of anchor clamps of using when utilizing the diameter run-out of beat instrument testing automobile part.
Background technology
Most of revolving part on the automobile need carry out diameter run-out to it usually during fabrication and detect, with the dynamic balance performance of test revolving part.Beat instrument instrument commonly used when detecting diameter run-out, the monitor station of beat instrument is provided with thimble or the register pin that matches with the turning axle upper shaft hole, makes axle around its rotation, utilizes gauge head to the axle test of layouting then.If but axis holes such as test flywheel are bigger, in the time of can't using the part of thimble positioning and fixing, owing to lack anchor clamps, can cause difficulty to testing.The Chinese utility model patent instructions of the CN2727691Y of on September 21st, 2005 bulletin discloses a kind of bent axle comprehensive detection device, and two cover push pin device are installed on the base of this device, is used for the positioning and fixing bent axle.This device can be used for detecting parts such as bent axle, but when detecting the beating of parts such as flywheel if desired, because the axis hole on the flywheel is bigger, can't use thimble to locate and fix, so just, the range of application to this device has caused restriction, universal not strong, when detecting, also need other equipment to come the bigger part of axis holes such as flywheel is tested, cost is higher.
The utility model content
The utility model mainly is to solve the beat instrument that exists in the prior art when detecting the bigger part of axis hole such as flywheel, can't use thimble to locate and fix, the problem that testing has difficulties, a kind of beat instrument anchor clamps are provided, these anchor clamps can be installed on the beat instrument, the convenient diameter run-out that detects parts such as flywheel.
In order to solve the problems of the technologies described above, the utility model has adopted a kind of like this beat instrument anchor clamps, described anchor clamps comprise a multidiameter, described multidiameter comprises an a, the shaft shoulder and axle b, described axle a and axle b are positioned at the two ends of multidiameter, on the end face of described axle a and axle b a pilot hole is set respectively, described pilot hole is coaxial with described multidiameter, fixes a scroll chuck on described axle b.Utilize on thimble on the beat instrument and the multidiameter location of the cooperation between the pilot hole and fix these anchor clamps, because pilot hole is coaxial with multidiameter, the described dynamic balance performance that can guarantee these anchor clamps.Fixed a scroll chuck on the axle b, utilized the shaft shoulder to carry out spacing it.Because scroll chuck can be regulated the radial position of three pawls, just can detect the diameter of the axis hole size adjustment scroll chuck of workpiece as required.The utility model provides the unit clamp that uses on a kind of beat instrument, can use common beat instrument that the big workpiece of axis holes such as flywheel is carried out diameter run-out like this detects, and the diameter of scroll chuck is adjustable, and then has improved range of application of the present utility model, and versatility is stronger.
As preferably, the end of described axle b comprises a thread spindle, is provided with stop nut on described thread spindle.After on the scroll chuck workpiece being installed, can utilize stop nut with Work-sheet pressing, improve the stability when detecting, improve security simultaneously, workpiece is difficult for landing.
As preferably, between described stop nut and described scroll chuck, circular baffle plate is set.Increased the contact area between stop nut and the workpiece like this, when improving stability maintenance, can also avoid the scuffing of nut workpiece.
The beneficial effects of the utility model have provided the unit clamp that uses on a kind of beat instrument, can use common beat instrument that the big workpiece of axis holes such as flywheel is carried out diameter run-out like this detects, and the diameter of scroll chuck is adjustable, and then having improved range of application of the present utility model, versatility is stronger.Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of beat instrument of the present utility model comprises a multidiameter 1 and a scroll chuck 2 with anchor clamps, described multidiameter comprises an a11, the shaft shoulder 12 and axle b13, and described axle a11 and axle b13 are positioned at the two ends of described multidiameter 1, and described scroll chuck 2 is fixed on the described axle b13.The end of described axle b13 comprises a thread spindle 4, and circular baffle plate 3 and stop nut 6 are set on the thread spindle 4, on the end face of the thread spindle 4 of described axle b13 and axle a11 pilot hole 5 is set respectively, and described pilot hole 5 is coaxial with multidiameter 1.
During test, the axis hole of workpiece is arranged on the scroll chuck, regulates the radial position of three pawls on the scroll chuck, location and fixation workpiece, circular baffle plate and stop nut are installed on the thread spindle of axle b, fastening nut utilize circular baffle plate with Work-sheet pressing on scroll chuck.Utilize on thimble on the beat instrument and the multidiameter location of the cooperation between the pilot hole and fix these anchor clamps, because pilot hole is coaxial with multidiameter, the described dynamic balance performance that can guarantee these anchor clamps.The utility model provides the unit clamp that uses on a kind of beat instrument, can use common beat instrument that the big workpiece of axis holes such as flywheel is carried out diameter run-out like this detects, and the diameter of scroll chuck is adjustable, and then has improved range of application of the present utility model, and versatility is stronger.
