Embodiment Construction

[0017] Referring to Fig. 1, Fig. 2 and Fig. 3, the sample punch calibration body 1 is approximately cuboid, and the middle part is retracted to facilitate the operator to hold. The upper and lower planes of the calibration body 1 are parallel planes, and the four corners of the lower end of the calibration body 1 pass The threaded connection is equipped with adjusting legs 6, each leg 6 is screwed with a set nut 7, after adjusting the length of the legs 6, it is tightened with the set nut 7 to prevent loosening, there is a vertical guide hole in the middle of the correction body 1, the correction body The two ends of the vertical guide hole of 1 are circular holes with enlarged diameters, the center line of the guide hole is perpendicular to the upper and lower sides and is on the geometric center of the correction body 1, the sample punch 3 is housed in the guide hole, and the middle guide of the sample punch 3 The rod part fits with the vertical guide hole of the correction b...

Abstract

A kind of sample puncher correction device has adjustable uphold feet set on the four corners below of the device, there is a vertical lead-hole in the central section, the transmit bar in the middle of the sample puncher is located in the lead-hole and clearance cooperation, the top of the sample puncher stretch beyond the upside of the device, there is a bulgy platform at the under of the sample puncher, fix a cap on the top of it, and sheath a press-spring on the top whose two ends uphold between the correction body and sample puncher cap, on the upside plane of the correction body set a air bubble gradient, at the center of a side on the underside plane set a observe window, set a multi-claw wheel at the transverse hatch on the wall which is between the enlarge diameter round hole and outside profile. The device makes the sample puncher keep the vertical station to the part, and can avoid deflect of the sample rush hole and assure the machining precision.

Description

Technical field: [0001] The invention relates to a fitter's sample punch correction device, which is used in the technical process of fitter's sample punching. Background technique: [0002] The proofing and punching process is an indispensable measure in the production process to ensure that the dimension boundary line in the process is not damaged and to improve the processing accuracy since the manufacturing industry. However, due to the absence of very precise sample punching tools, there are still product quality declines and unqualified products caused by errors in sample punching in production. Especially for hole processing, the factor of punching and guiding the drill bit is very large. The error of a single hole is 1-30 wires, and the error between holes is difficult to control. Invention content: [0003] The object of the present invention is to provide a sample punching calibrator, which solves the problem that the hole shape and position errors are easy to b...
