Description

Technical Field

[0001] This application relates to the technical field of measurement tooling, and particularly to a measuring tool for the inner and outer diameters of a casing product. Background Art

[0002] In the machining of parts on a lathe, there are often many dimensions that cannot be directly measured and can only be indirectly measured by dial indicator. When using a dial indicator, it is generally impossible for an ordinary lathe to quickly and accurately find the highest point in the radial direction of the workpiece. For the inner and outer diameters of products with high tolerance requirements, directly using a dial indicator to calculate the drop value cannot guarantee the accuracy. Conventional dial indicator measurement can only be used for rough tolerance or for checking the height difference in the Z direction. Summary of the Utility Model

[0006] Optionally, a dovetail-shaped slide rail is arranged at the bottom of the fixed slide base, and a dovetail-shaped chute matching the dovetail-shaped slide rail is arranged on the slider.

[0007] Optionally, the measuring bracket includes a magnetic base, a connecting bracket and a dial indicator mounting base. The magnetic base is adsorbed on the slider, one end of the connecting bracket is connected to the magnetic base, and the other end is connected to the dial indicator mounting base. The dial indicator is fixedly arranged on the dial indicator mounting base.

[0008] Optionally, a baffle is fixedly installed on one side of the fixed slide base through a bolt, and a washer is sleeved on one end of the bolt extending into the inner side of the baffle.

The machine tool spindle drives the dial indicator to contact the product to be measured, and the slider drives the dial indicator to move along the edge of the product to be measured. The point where the maximum value measured by the dial indicator is located is the highest point of the product, so as to quickly and accurately measure the position of the highest point of the product.

[0014] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0015] It should be noted that all directional indications (such as up, down, left, right, front, back,...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, the directional indications will also change accordingly.

[0016] In the present application, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0017] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B at the same time. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0018] Refer to the attached Figure 1, an embodiment of the present application provides a measuring tool for the inner and outer diameters of a casing product, including a fixed slide base 1, a slider 2, a measuring bracket, and a dial indicator 9. Among them, the fixed slide base 1 is an L-shaped structure, and its vertical section is assembled on the machine tool spindle, so that the measuring tool is brought close to and contacted with the workpiece to be measured through the movement of the machine tool spindle. A dovetail rail 101 is integrally formed at the bottom of the horizontal section of the fixed slide base 1. The slider 2 is provided with a dovetail groove and is slidably mounted on the dovetail rail 101 through the dovetail groove, so that it can slide horizontally on the fixed slide base 1. A baffle 3 is fixedly installed on one side of the fixed slide base 1 through a bolt 5. The baffle 3 enables the slider 2 to be installed only from one side of the dovetail rail 101 and restricts the slider 2 from sliding out on the other side. A washer 4 is provided at one end of the bolt 5 installed on the baffle 3 that extends into the inner side of the baffle 3, which can play a buffering role during the process of moving the slider 2.

[0019] Among the above, the measuring bracket includes a magnetic base 6, a connecting bracket 7, and a dial indicator mounting seat 8. The magnetic base 6 is adsorbed on the slider 2. One end of the connecting bracket 7 is fixedly connected to the magnetic base 6, and the other end is connected to the dial indicator mounting seat 8. The dial indicator mounting seat 8 is provided with a mounting hole, and the dial indicator 9 is inserted into the mounting hole and fixed to the dial indicator mounting seat 8.

[0020] From the above, for a measuring tool for the inner and outer diameters of a casing product provided by an embodiment of the present application, when in use, first, the fixed slider 2 is assembled on the machine tool spindle, the slider 2 is installed on the dovetail rail 101, the magnetic base 6 is adsorbed on the slider 2, and then the machine tool spindle is moved to make the dial indicator 9 contact the workpiece to be measured. At this time, the measuring head of the dial indicator 9 is pressed and a reading will be shown on the dial indicator 9. Then, by moving the slider 2, the dial indicator 9 is driven to move. During the movement, the dial indicator 9 remains in contact with the workpiece to be measured and shows different readings. Since the highest point of the workpiece is relatively protruding, it will cause a large deformation of the dial indicator 9 due to extrusion. Therefore, the reading of the dial indicator 9 is the largest at the highest point. Therefore, by finding the point where the reading of the dial indicator 9 is the largest, the highest point of the workpiece can be obtained.

[0021] It can be seen that for a measuring tool for the inner and outer diameters of a casing product proposed by an embodiment of the present application, by setting the fixed slide base 1 to be connected to the machine tool spindle, the machine tool spindle is used to drive the dial indicator 9 to contact the product to be measured, the slider 2 is used to drive the dial indicator 9 to move along the edge of the product to be measured, and the point where the maximum value measured by the dial indicator 9 is located is the highest point of the product, so as to quickly and accurately measure the position of the highest point of the product.

[0022] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
