Description

A kind of oblique feeler gauge for extrusion barrel measurement

technical field

The invention relates to the technical field of extrusion barrel measurement, and more specifically, relates to an inclined feeler gauge for extrusion barrel measurement.

Background technique

Feeler gauge, also known as micrometer or thickness gauge, is one of the measuring instruments used to check the gap. The cross section of the feeler gauge is a right triangle with a scale on the hypotenuse. The length of the short side is directly expressed in on the hypotenuse so that the size of the seam can be read directly. There are multiple pieces of feeler gauge with different thicknesses. When measuring, insert the thinner piece of feeler gauge into the gap under test first. If there is still a gap, select the thicker one and insert it in sequence until the feeler gauge just fits into the gap. Whether it is not loose or tight, the thickness of the feeler gauge is the size of the measured gap. If there is no feeler gauge of the required thickness, multiple pieces of feeler gauges can be used to superimpose, and the measured gap is the sum of the dimensions of each piece of feeler gauge.

When adjusting the center of the extrusion barrel of the extruder, it is necessary to use a feeler gauge to measure the gap between the inner wall of the extrusion barrel and the extrusion shaft, up, down, left and right. However, when workers use the feeler gauges of the prior art, they often need to try out feeler gauge pieces of various specifications, repeatedly insert the gap measurement, and exchange repeatedly. Convenience, low work efficiency.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The oblique feeler gauge used for extrusion cylinder measurement provided by the embodiment of the present application can refer to accompanying drawings 1 to 4 of the specification, including: a feeler gauge body 1 and a sliding body 2, and the sliding body 2 is along the length direction of the feeler gauge body 1 Sliding setting, the bottom surface of the feeler gauge body 1 is set as a horizontal plane, the top surface of the feeler gauge body 1 is set as an inclined surface, and the intersection between the top surface and the bottom surface forms an inclination angle. The extrusion cylinder 3, the end surface of the sliding body 2 and the end surface of the extrusion cylinder 3 are bonded.

It should be noted that the bottom surface of the feeler gauge body 1 intersects with the slope, and its shape is similar to a triangular prism, and the thickness of the feeler gauge body 1 increases from one end to the other end. When using the inclined feeler gauge for measurement, the end of the feeler gauge body 1 with a small thickness is inserted into the gap between the extrusion cylinder 3 and the extrusion shaft. When the feeler gauge body 1 cannot continue to be inserted into the gap, the sliding body 2 is moved until it slides The end surface of the body 2 close to the end of the extrusion cylinder 3 is attached to the end surface of the extrusion cylinder, then the position of the sliding body 2 relative to the feeler gauge body 1 is fixed, and then the oblique feeler gauge is pulled out, and the measurement gap value is read according to the position of the sliding body 2 , the inclined feeler gauge can be convenient for workers to measure and use, improve work efficiency, and can effectively reduce errors. The inclination angle of the top surface and the bottom surface of the oblique feeler gauge has a certain range. In the specific embodiment provided by the application, the length of the oblique feeler gauge is 200 millimeters, and the thickness is 20 millimeters. The ratio of the two is 10 to 1. The size can be set according to actual production needs, and this article does not make a limit.

As shown in accompanying drawings 1 and 2 of the specification, both sides of the feeler gauge body 1 are provided with slide rails 11 , the slide rails 11 are arranged along the length direction of the feeler gauge body 1 , and the sliding body 2 slides along the slide rails 11 . The sliding body 2 is slidably arranged relative to the feeler gauge body 1. In order to facilitate the stable sliding of the sliding body 2, two slide rails 11 are arranged in parallel on both sides of the feeler gauge body 1. groove, so that the sliding body 2 can move smoothly on the feeler gauge body 1.

The end surface of the sliding body 2 in contact with the extrusion cylinder 3 is perpendicular to the bottom surface. The sliding body 2 is close to one end of the extrusion cylinder 3. In order to ensure a close fit with the end surface of the extrusion cylinder 3, the end surface of the sliding body 2 is parallel to the end surface of the extrusion cylinder 3, perpendicular to the bottom surface of the feeler gauge body 1, and perpendicular to the feeler gauge body. The slope of 1 forms an obtuse angle, which enables accurate readings.

A scale is arranged on the inclined surface, and the scale corresponds to the thickness of the feeler gauge body 1 . After the measurement is completed, in order to facilitate the workers to read the results of the gap measurement, the slope of the feeler gauge body 1 is provided with a scale value, which is the same as the thickness of the feeler gauge body 1, so that the sliding body 2 faces the end surface of the extrusion cylinder 3 The value can be read at the position intersecting the slope of the feeler gauge body 1, which is the size of the gap.

The sliding body 2 is provided with a compression bolt 21, the compression bolt 21 is arranged along a direction perpendicular to the slope, and the bottom surface of the compression bolt 21 is parallel to the slope. The setting of the pressing bolt 21 can fix the position of the sliding body 2 relative to the feeler gauge body 1. The sliding body 2 is provided with a threaded through hole along the direction perpendicular to the slope of the feeler gauge body 1. The pressing bolt 21 is screwed into the threaded through hole, and the pressing When the tightening bolt 21 is tightened, the sliding body 2 is fixed relative to the feeler gauge body 1 , and when the pressing bolt 21 is loosened, the sliding body 2 slides relative to the feeler gauge body 1 . Before the measurement, unscrew the compression bolt 21, when the feeler gauge body 1 is inserted into the gap until it is stuck, so that the sliding body 2 is close to the end surface of the extrusion cylinder 3, at this time, tighten the compression bolt 21, so that the The feeler gauge body 1 prevents the sliding body 2 from moving, which affects the measurement effect, and can also ensure the accuracy of the measured value when the measurement is turned over. Of course, there are many ways to fix the sliding body 2. For example, a block is set on the sliding body 2, and the block is rotated so that the block is fixed relative to the feeler gauge body 1, as long as the sliding body 2 is fixed relative to the feeler gauge body 1. That’s it, and there is no limitation in this article.

The material of the feeler gauge body 1 is made of high-temperature-resistant and wear-resistant steel. Since the temperature of the feeler gauge body 1 is high when measuring in the extrusion cylinder 3, the material of the feeler gauge body 1 needs to be a material that is less affected by temperature and is not easily deformed. The body 1 of the feeler gauge will cause sliding friction between the body 1 of the feeler gauge and the extrusion cylinder 3 and/or the extrusion shaft. In order to reduce the wear of the body 1 of the feeler gauge, the material of the body 1 of the feeler gauge needs to have wear-resistant properties, such as Materials such as alloy tool steel can be used.

As shown in Figure 4 of the description, the steps of using the inclined feeler gauge for extrusion cylinder measurement provided by the present application include: loosening the compression bolt 21, sliding body 2 relative to the feeler gauge body 1; inserting the feeler gauge body 1 The gap between the extrusion cylinder 3 and the extrusion shaft until the feeler gauge body 1 is stuck; the sliding body 2 slides towards the extrusion cylinder 3 until the end faces of the two are attached to each other; tighten the compression bolt 21, and pull out the feeler gauge body 1. Read the measured value.
