Technical Field

[0001] This utility model relates to the field of quality inspection measuring tools, specifically a measuring tool device for testing universal joint shells. Background Technology

[0002] Measuring tools and equipment generally refer to various tools, devices, and equipment used for measurement in manufacturing and scientific research. In the field of automobile manufacturing, measuring tools and equipment are even more essential. Automobiles contain a large number of parts, and the dimensions of each part need to meet the standards to ensure stable operation after the parts are assembled. Therefore, dimensional inspection is also unavoidable when producing universal joint housings.

[0003] The measuring tools and methods for detecting the outer diameter and height of universal joint housings are very common in the field of machining. Dial indicators, lever indicators, vernier calipers or height gauges are commonly used for measurement. However, the universal joint housing has a cavity that needs to be measured in depth. The above measuring tools cannot directly measure this depth. Therefore, in order to facilitate the detection of the cavity depth of the universal joint housing, our company has designed and proposed a special measuring tool for detecting universal joint housings. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a measuring tool for testing universal joint housings, which facilitates the quality measurement of the cavity depth of universal joint housings.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A measuring tool for testing universal joint housings includes a fixed base, on which a positioning cylinder for placing an inverted universal joint housing is vertically fixed. The front of the positioning cylinder is vertically provided with an opening clearance groove, the width of which is greater than the diameter of the shaft of the universal joint housing. The top of the inner wall of the positioning cylinder is provided with a positioning ramp that matches the shape of the outer wall of the universal joint housing.

[0007] The fixed base is also vertically fixed with a column located on one side of the positioning cylinder. A bracket is horizontally fixed on the top of the column, and a dial indicator located directly above the universal joint housing is vertically mounted on the bracket.

[0008] The surface of the column is rotatably fitted with a movable sleeve. The upper end of the movable sleeve is horizontally fixed with a connecting arm. The end of the connecting arm is fixed with a limiting seat that can rotate around the column to directly below the dial indicator. An extension rod is vertically and movably inserted into the limiting seat. The lower end of the extension rod is supported on the bottom of the inner wall of the universal joint housing, and the upper end of the extension rod is supported on the bottom of the dial indicator's measuring rod.

[0009] Preferably, the bottom of the positioning cylinder is provided with an integrally constructed widened flange for connection with the fixed base.

[0010] Preferably, the column is a smooth cylindrical rod, and the top and bottom of the movable sleeve are both inlaid with bearings installed on the surface of the column.

[0011] Preferably, the extension rod is a smooth round rod with a hemispherical lower end and an integrally fixed connecting cap at the upper end, the connecting cap being disc-shaped.

[0012] Preferably, the limiting seat is movably sleeved on the surface of the extension rod through a limiting hole set vertically in the center, and the top of the limiting seat is provided with a limiting groove that matches the shape of the connecting cap.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention features a positioning cylinder for positioning an inverted universal joint housing. A height-adjustable extension rod is inserted into the cavity of the universal joint housing and supported at the bottom of the inner wall. Each type of universal joint housing corresponds to a specific measuring tool. A dial indicator with a fixed installation height measures the difference between the upper end of the extension rod and the standard height. Since the length of the extension rod is fixed, it is convenient to check whether the depth of the universal joint housing cavity meets the standard. The structure is simple, easy to use, and suitable for widespread application. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5 As shown, this utility model provides a technical solution: a measuring tool for testing universal joint housings, including a fixed base 1, a positioning cylinder 3 for placing an inverted universal joint housing 2 is vertically fixed on the fixed base 1, and the bottom of the positioning cylinder 3 is provided with an integrated structure for connecting to the fixed base 1 with a widened flange 303, which increases the diameter of the fixed position, improves the structural stability, and helps to ensure that the position is vertical.

[0023] The front of the positioning cylinder 3 is vertically provided with an opening relief groove 301. The width of the opening relief groove 301 is greater than the shaft diameter of the universal joint housing 2, which makes it convenient to install the inverted universal joint housing 2 into the positioning cylinder 3 from the front. The top of the inner wall of the positioning cylinder 3 is provided with a positioning ramp 302 that matches the shape of the outer wall of the universal joint housing 2. The shape and size match well, which has a good positioning effect on the inverted universal joint housing 2.

[0024] A column 4 located on one side of the positioning cylinder 3 is also vertically fixed on the fixed base 1. A bracket 5 is horizontally fixed on the top of the column 4. A dial indicator 6 located directly above the universal joint housing 2 is vertically installed on the bracket 5. The position of the dial indicator 6 is fixed. When its measuring rod 601 is squeezed to different degrees, its pointer will rotate at different amplitudes. Based on the magnitude of the rotation amplitude, the difference between the height of the detection position and the height of the standard position can be obtained.

[0025] The surface of the column 4 is rotatably fitted with a movable sleeve 7. The column 4 is a smooth cylindrical rod. The top and bottom of the movable sleeve 7 are inlaid with bearings 11 installed on the surface of the column 4. The upper end of the movable sleeve 7 is horizontally fixed with a connecting arm 8. The end of the connecting arm 8 is fixed with a limiting seat 9 that can rotate around the column 4 to directly below the dial indicator 6. An extension rod 10 is vertically and movably inserted into the limiting seat 9. By rotating it to the front or back, the inverted universal joint housing 2 can be installed and disassembled with minimal pressure on the measuring rod 601.

[0026] The lower end of the extension rod 10 is supported on the bottom of the inner wall of the universal joint housing 2, and the upper end of the extension rod 10 is supported on the bottom of the measuring rod 601 of the dial indicator 6. The extension rod 10 is a smooth round rod with a hemispherical lower end and an integrally fixed connecting cap 1001 at the upper end. The connecting cap 1001 is disc-shaped. The limiting seat 9 is movably sleeved on the surface of the extension rod 10 through a vertically set limiting hole 901 in the center. The top of the limiting seat 9 is provided with a limiting groove 902 that matches the shape of the connecting cap 1001. The extension rod 10 can be kept vertical under the action of the limiting seat 9.

[0027] In use, rotate the connecting arm 8 and the limiting seat 9 around the column 4 to the front, invert the universal joint shell 2, and put it on the outside of the extension rod 10 from bottom to top. Rotate the connecting arm 8, the limiting seat 9 and the inverted universal joint shell 2 around the column 4 to the back. When it moves to the vicinity of the positioning cylinder 3, pull the measuring rod 601 upward to make room for the connecting cap 1001 of the extension rod 10. Move the inverted universal joint shell 2 slightly upward and then move it backward so that the shaft of the universal joint shell 2 enters the interior of the positioning cylinder 3 from the opening relief groove 301. Under the action of the positioning ramp 302 with a matching shape and size, the inverted universal joint shell 2 is placed stably on the positioning cylinder 3.

[0028] Loosen the measuring rod 601 of the dial indicator 6 so that its lower end contacts the upper surface of the connecting cap 1001. Slightly and slowly swing the connecting arm 8 back and forth. When the pointer of the dial indicator 6 indicates the minimum value, the lower end of the extension rod 10 is supported at the bottom of the inner wall of the universal joint housing 2. Each model of universal joint housing 2 corresponds to a model of this measuring tool. Measure the difference between the height position of the upper end of the extension rod 10 and the standard height position by using the dial indicator 6 with a fixed installation height. Since the length of the extension rod 10 is fixed, it is convenient to detect and judge whether the depth of the universal joint housing 2 cavity meets the standard.

[0029] When sliding the universal joint housing 2, the operation steps are reversed. Pull the measuring rod 601 upward to make room for the connecting cap 1001 of the extension rod 10. Move the inverted universal joint housing 2 upward slightly and then move it forward. After removing the universal joint housing 2 from the positioning cylinder 3, the universal joint housing 2 can be removed from below the extension rod 10.

[0030] In this solution, dial gauge 6 is a common product on the market that is familiar to technical personnel in the relevant field. Its structural principle, working principle, and operation method should be considered existing known technology and will not be described here. In addition, all components in this solution are regularly inspected and maintained according to actual usage conditions, and all vulnerable parts are replaced during maintenance according to wear and tear and usage time to ensure normal operation.
