JPH02189401A - Jig for measuring squareness of carrier - Google Patents

Abstract

PURPOSE:To make measurement simple and easy by providing a fixing base for exclusive use in measurement of a carrier and a pick tester which is a measuring apparatus. CONSTITUTION:A measuring tool is provided to measure a carrier 1 and a carrier positioning base 2 is provided to set and position the carrier 1 so that the carrier 1 is always measured under constant conditions. A fixing base 3 holds the base 2 and a pick tester fixing base 5. For measurement, a pickup tester 4 is brought into touch with the measuring position of the carrier 1 and the bases 5 and 3 are allowed to butt against the wall and slide, when the value is read. Thus, the measurement can be rendered simple and easy.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a carrier squareness measuring jig, particularly a jig for measuring the squareness of a carrier that holds a print head of a printer. This invention relates to a carrier squareness measuring jig that can easily measure the squareness by fixing the carrier with one touch.

[Conventional technology]

Conventionally, the squareness of the carrier has been measured using a coordinate measuring machine or by cutting it and using a projector.

Measurement using a three-dimensional measuring machine lacks accuracy due to the roughness of the measurement surface, and measurement using a projector requires cutting the carrier.

[Problem to be solved by the invention]

However, in the case of the above-mentioned conventional measurement method, since the carrier is a mold when using a coordinate measuring machine, the disadvantage is that it lacks accuracy due to the influence of surface roughness depending on the location where the measuring tip hits. There is.

In addition, the method using a projector has the disadvantage that the measurement point is inside the carrier, so the measurement must be performed after cutting, and although the roughness of the surface can be checked, the carrier must be destroyed.

[Means to solve the problem]

The carrier squareness measurement jig of the present invention has a carrier positioning base that can fix the carrier with one touch, a fixed base that holds it, and a pick tester fixed base for measurement, and the carrier positioning base and the fixed base are connected to each other. The positional relationship is set so that the squareness becomes 0 when the pick tester fixed base is slid, and the squareness is measured by the value when the pick tester is applied, so the condition of the measurement surface can be confirmed with the pick tester. Therefore, it is configured so that it can output accurate values.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a perspective view showing a state in which a carrier for measurement is set in an embodiment of the present invention, Fig. 2 is a detailed perspective view of the carrier positioning base shown in Fig. 1, and Fig. 3 is the same as Fig. 1. It is a partial perspective view which shows the measurement state of the carrier using the example shown.

The carrier squareness measuring jig shown in FIG. 1 includes a carrier positioning base 2, a fixed base 3, a pick tester 4, and a pick tester fixed base 5.

The carrier squareness measuring jig shown in Fig. 1 is for measuring the carrier 1, and the carrier positioning base 2 is for setting the carrier 1 and always measuring the carrier 1 under constant conditions. Perform positioning for this purpose. The fixed base 3 holds the carrier positioning base 2 and the pick tester fixed base 5. When measuring, the pick tester 4 is placed on the measurement location of the carrier 1, and the pick tester is slid against the walls of the pick tester fixed base 5 and the fixed base 3 to read the value.

Note that when the carrier 1 is set on the carrier positioning base 2, it is set using the guide shaft part 6 and the rear stay part 7.

〔Effect of the invention〕

The carrier squareness measuring jig of the present invention has the effect of simplifying the measurement because it enables measurement by setting the fixed base dedicated to carrier measurement and the measuring device Pi with a single touch.
