Description

Technical Field

[0001] This utility model relates to the field of inspection tool technology, and in particular to a dial indicator type tooling inspection tool. Background Technology

[0002] The contact support is an important component in a circuit breaker. This part is a stamped component, as shown in the instruction manual. Figure 5 As shown, dimensions a and b on the part are critical dimensions. The accuracy of these dimensions affects the reliability of the slow reset performance of the product mechanism. However, they cannot be accurately measured with vernier calipers. If a projector is used for measurement, it is not only inefficient but also cannot meet the requirements of process inspection in the production process. In view of the above-mentioned defects, this application is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a dial indicator-type tooling fixture that solves the current problems of difficulty in measuring key dimensions of contacts and low measurement efficiency.

[0004] To address the aforementioned problems, this utility model provides a dial indicator-type tooling fixture, comprising a limiting plate, a support body, a positioning shaft, and a top dial indicator support structure. One end of the positioning shaft is connected to the support body, while the other end is open for loading the part to be measured into the positioning shaft. The support body supports the part to be measured and keeps it in position. The contact support is installed at the positioning shaft and can rotate around the positioning shaft, thus eliminating the need for the contact support to be installed at a specific angle. The distance between the axis of the positioning shaft and the limiting plate is the standard size of the part to be measured. The top dial indicator support structure is used to install the top dial indicator.

[0005] According to one embodiment of the present invention, the dial indicator tooling fixture further includes a top dial indicator, which can be installed at the top dial indicator support structure to measure the part to be measured. The measuring end of the top dial indicator contacts one side of the contact support, and the other side of the contact support contacts the limiting plate. The measurement is completed by reading the top dial indicator.

[0006] According to one embodiment of the present invention, the top table support structure includes a top table mounting hole and a top table fixing component. The top table is installed at the top table mounting hole and fixed by the top table fixing component.

[0007] According to one embodiment of the present invention, the top surface fixing assembly includes bolts and bolt holes, and is fixed by tightening the bolts.

[0008] According to one embodiment of the present invention, the bolt holes are provided in two or more sets, which are respectively located in different positions, so that the bolts can be installed in a convenient and suitable position to fix the top surface.

[0009] According to one embodiment of the present invention, the limiting plate, the support body, and the top support structure are all mounted on the base.

[0010] According to one embodiment of the present invention, the limiting plate is movable and used to adjust the distance between it and the positioning shaft. For example, several limiting plate installation positions are provided on the base so that it can support the detection of contacts of different sizes and models.

[0011] According to one embodiment of the present invention, the open end of the positioning shaft has a tapered portion, which facilitates the insertion of the contact support.

[0012] The beneficial effects of this utility model are that by setting a limiting plate, a support body, and a positioning shaft, the positioning shaft is used for the contact support to be installed on the positioning shaft. The contact support can rotate around the positioning shaft as the center when it is installed at the positioning shaft. Therefore, it is not necessary to install the contact support at a specific angle. The horizontal distance between the axis of the positioning shaft and the limiting plate is the standard dimension 'a' of the part to be measured. The measuring end of the top gauge contacts one side of the contact support, and the other side of the contact support contacts the limiting plate. The measurement is completed by reading the top gauge, which greatly improves the measurement efficiency and the accuracy of the measurement results. Attached Figure Description

The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0020] Example 1:

[0021] A dial indicator type tooling inspection fixture, such as Figure 1It includes a base 1, a limiting plate 2, a support body 3, a positioning shaft 4, a top surface support structure 5, and a top surface 6. The limiting plate 2, the support body 3, and the top surface support structure 5 are all installed on the base 1, and the base 1 can be placed stably on the workbench.

[0022] The support body 3 is preferably a cylinder. One end of the positioning shaft 4 is connected to the top of the support body 3, and the other end is open for the contact support 7 to be inserted into the positioning shaft 4. The upper end face of the support body 3 is used to support the contact support 7 and keep it in position. The contact support 7 can rotate about the positioning shaft 4 after being installed at the positioning shaft 4, so it is not necessary to install the contact support 7 at a specific angle. Figure 3 The horizontal distance between the axis of the positioning shaft 4 and the limiting plate 2 is the standard dimension a of the part to be measured.

[0023] The top gauge support structure 5 is used to install the top gauge 6. The top gauge 6 can be installed on the top gauge support structure 5 to measure the part to be measured. The top gauge support structure 5 includes a top gauge mounting hole 52 and a top gauge fixing component 51 set on the support block. The top gauge 6 is installed at the top gauge mounting hole 52. In this embodiment, the top gauge fixing component 51 includes bolts and bolt holes. It is fixed by tightening the bolts. There are two or more sets of bolt holes, which are set in different positions. The bolts can be installed at a convenient and suitable position to fix the top gauge.

[0024] Place the sample on the tooling fixture to calibrate the top gauge. Gently pull the handle of the top gauge 6 outward and then release it. Record the reading at this time as c, which serves as the reference value. A tolerance of ±0.05mm is allowed. The contact support 7, which is subsequently processed, is installed on the positioning shaft 4. The measuring end 62 of the top gauge 6 contacts one side of the contact support 7, and the other side of the contact support 7 contacts the limiting plate 2. The measurement of the top gauge 6 is completed. If the reading meets c ± 0.05, it is a qualified product.

[0025] Example 2:

[0026] Based on Embodiment 1, in this embodiment, in order to adapt to the detection work of contact support 7 of different sizes and models, the limiting plate 2 is movable and used to adjust the distance between it and the positioning shaft 4. The movable method can be selected by setting several installation positions of the limiting plate 2 on the base 1, and installing the limiting plate 2 in different positions for adjustment so that it can detect contact support 7 of different sizes and models.

[0027] Preferably, the open end of the positioning shaft 4 has a tapered portion to facilitate the insertion of the contact support 7.

[0028] Optionally, the positioning shaft 4 can be configured such that its diameter gradually decreases from one end to the other. The top support structure 5 is configured as a telescopic rod, which can accommodate different types of contact supports 7 mounted on the positioning shaft 4. The structure of the telescopic rod allows the top meter 6 to be adjusted in height.
