Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy shell aperture detection technology, and in particular to a go / no-go detection tool. Background Technology

[0002] In actual production, it is very time-consuming to measure each product individually using measuring instruments (such as vernier calipers, dial indicators, etc.) in large quantities.

[0003] Qualified aluminum alloy products have a measurement range, and those within this range are considered qualified. Go and no-go gauges are a type of gauge used as a measurement standard for large-scale inspection. Therefore, qualified products are generally measured using go and no-go gauges, and the two processes are carried out separately. The go gauge is the lower limit of the allowable deviation of the hole diameter, while the no-go gauge is the upper limit of the allowable deviation of the hole diameter.

[0004] However, if the go / no-go gauge is left lying on the surface of the testing station when not in use, it can easily cause wear on both ends of the gauge, which can lead to deviations in the test data over time. Utility Model Content

[0005] The purpose of this utility model is to provide a go / no-go testing tool, which solves the problem that when go / no-go gauges are not in use, they are placed arbitrarily on the surface of the testing table, which easily leads to wear on both ends of the go / no-go gauges and causes deviations in the test data over time.

[0006] To achieve the above objectives, this utility model provides a go / stop detection tool, comprising a main body, a support rod, a hook, a top rod, and a washer; the support rod is fixedly connected to the main body and located on the outside of the main body, the hook is fixedly connected to the support rod and located at the end of the support rod away from the main body, the top rod is fixedly connected to the main body and located at the end of the main body away from the support rod, and the washer is fixedly connected to the top rod and located at the end of the top rod away from the main body.

[0007] The go / no-go testing tool further includes a go gauge and a no-go gauge. The go gauge is fixedly connected to the main body and located at the end of the main body near the support rod. The no-go gauge is fixedly connected to the main body and located at the end of the main body away from the go gauge.

[0008] The end of both the go gauge and the stop gauge furthest from the main body is provided with a near-chamfer.

[0009] The go / stop detection tool also includes a handle, which is fixedly connected to the main body and located between the support rod and the top rod.

[0010] The surface of the grip is provided with anti-slip grooves.

[0011] This utility model discloses a go / no-go gauge testing tool. The main body provides overall support for the tool. The support rod supports the hook and the main body. The hook hangs the main body on a workbench. The top rod supports the pad, and the pad increases the friction between the top rod and the workbench. When the tool is not used for a short period, the main body is placed on the workbench surface, with the hook and pad in contact with the surface. The support rod and top rod provide support to the main body, preventing slippage of the main body, go gauge, and no-go gauge, thus avoiding damage to the go and no-go gauges. When the tool is not used for a long period, the main body is hung on the workbench using the support rod and hook. The top rod and pad support the bottom of the main body, keeping it vertical and preventing damage to the go and no-go gauges. This invention solves the problem of go and no-go gauges being carelessly placed on the surface of the testing table when not in use, which easily leads to wear at both ends and, over time, deviations in the test data.

[0015] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0016] The first embodiment of this application is as follows:

[0017] Please see Figure 1 , Figure 1This is a schematic diagram of the overall structure of the go / no-go testing tool according to the first embodiment of the present invention. The present invention provides a go / no-go testing tool, including a main body 101, a support rod 102, a hook 103, a top rod 104, a gasket 105, a go gauge 106, a no-go gauge 107, and a handle 109. The aforementioned solution solves the problem that when the go / no-go gauge is not in use, it is placed randomly on the surface of the testing table, which easily leads to wear on both ends of the go / no-go gauge, and over time, this leads to deviations in the testing data.

[0018] In this specific embodiment, the support rod 102 is fixedly connected to the main body 101 and located on the outside of the main body 101. The hook 103 is fixedly connected to the support rod 102 and located at the end of the support rod 102 away from the main body 101. The top rod 104 is fixedly connected to the main body 101 and located at the end of the main body 101 away from the support rod 102. The pad 105 is fixedly connected to the top rod 104 and located at the end of the top rod 104 away from the main body 101. The main body 101 provides support for the tool as a whole. The support rod 102 provides support for the hook 103 and the main body 101. The hook 103 is used to hang the main body 101 on the workbench. The top rod 104 provides support for the pad 105. The pad 105 is used to increase the weight of the tool. The friction between the top rod 104 and the worktable is used to prevent the main body 101 from slipping on the worktable surface when the testing tool is not in use for a short period of time. At this time, the hook 103 and the pad 105 are in contact with the worktable surface. The support rod 102 and the top rod 104 provide support for the main body 101, preventing the main body 101, the go gauge 106, and the no-go gauge 107 from slipping on the worktable and avoiding damage to the go gauge 106 and the no-go gauge 107. When the tool is not in use for a long time, the main body 101 is hung on the worktable by the support rod 102 and the hook 103. At this time, the top rod 104 and the pad 105 support the bottom of the main body 101, so that the main body 101 remains vertical after being hung up, avoiding damage to the go gauge 106 and the no-go gauge 107.

[0019] The go gauge 106 is fixedly connected to the body 101 and located at one end of the body 101 near the support rod 102. The stop gauge 107 is fixedly connected to the body 101 and located at one end of the body 101 away from the go gauge 106. The go gauge 106 is used to detect the size of the aluminum alloy hole, and its size is the lower limit of the allowable deviation of the hole diameter. The stop gauge 107 is used to detect the size of the aluminum alloy hole, and its size is the upper limit of the allowable deviation of the hole diameter. In use, the go gauge 106 is first inserted into the hole. If it cannot be inserted, the hole diameter is too small. If it can be inserted, the stop gauge 107 is then inserted into the hole. If the stop gauge 107 can be inserted into the hole, the hole diameter is too large. If the stop gauge 107 cannot be inserted into the hole, the hole diameter is qualified.

[0020] Secondly, both the go gauge 106 and the stop gauge 107 have a chamfer 108 at the end away from the main body 101. The chamfer 108 facilitates the guidance of the go gauge 106 and the stop gauge 107.

[0021] Furthermore, the go / stop detection tool also includes a handle 109, which is fixedly connected to the main body 101 and located between the support rod 102 and the top rod 104. The handle 109 facilitates the control of the main body 101.

[0022] Finally, the surface of the grip 109 is provided with anti-slip grooves 110 composed of multiple sets of positive spirals and multiple sets of negative spirals. The anti-slip grooves 110 are used to increase the friction between the grip 109 and the worker's hand.

[0023] Using the go / stop testing tool of this embodiment, the main body 101 provides support for the entire tool. The support rod 102 provides support for the hook 103 and the main body 101. The hook 103 is used to hang the main body 101 on the workbench. The top rod 104 provides support for the pad 105, which increases the friction between the top rod 104 and the workbench. When the testing tool is not used for a short period, the main body 101 is placed on the surface of the workbench. At this time, the hook 103 and the pad 105 are in contact with the workbench surface, and the support rod 102 and the top rod 104 provide support for the main body 101. The purpose of this design is to prevent the main body 101, the go gauge 106, and the no-go gauge 107 from sliding off the table, thus avoiding damage to the go gauge 106 and the no-go gauge 107. When the tool is not in use for a long time, the main body 101 can be hung on the workbench via the support rod 102 and the hook 103. At this time, the top rod 104 and the pad 105 support the bottom of the main body 101, keeping the main body 101 vertical after being hung up, thus avoiding damage to the go gauge 106 and the no-go gauge 107. This solves the problem that when the go and no-go gauges are not in use, they are easily placed on the surface of the testing table, which can easily lead to wear on both ends of the go and no-go gauges, resulting in deviations in the test data over time.

[0024] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
