[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0028] This application provides a tooling for detecting the arc depth of an external planetary gear blank, which can solve the problem that the depth accuracy of the assembly surface of the product under test is low and it is inconvenient to use.

[0029] Reference Figure 1The application discloses a detection tool for the arc depth of an outer planet wheel blank, which comprises a handheld handle, a fixed seat, a digital dial gauge and a movable test plate. The fixed seat and the digital dial gauge are arranged at two ends of the length direction of the handheld handle, and the fixed seat is fixedly connected to the handheld handle. The digital dial gauge is movably arranged at the other end of the handheld handle. The movable test plate is arranged at one end of the handheld handle where the fixed seat is arranged, and the movable test plate is connected to the digital dial gauge through a reciprocating pushing piece. When an operator holds the handheld handle and pushes the digital dial gauge, the digital dial gauge can push the movable test plate to extend away from the fixed seat through the reciprocating pushing piece. The cross-sectional dimension of the fixed seat is not less than the cross-sectional dimension of a product to be detected. In use, the fixed seat is abutted against the surface of the product to be detected. The cross-sectional dimension of the movable test plate is adapted to the cross-sectional dimension of the assembly bottom surface of the product to be detected. The operator pushes the digital dial gauge, so that the movable test plate moves away from the fixed seat, i.e. moves towards the inside of the product to be detected. Since the cross section of the movable test plate is adapted to the cross-sectional dimension of the assembly surface, when the digital dial gauge cannot continue to push the movable test plate to move, the movable test plate has contacted the assembly surface of the product to be detected. At this time, the reading of the digital dial gauge plus the distance between the movable test plate and the fixed seat is the distance of the assembly surface of the product to be detected. The detection tool is convenient to use, and the precision of the assembly surface depth of the product to be detected is greatly improved. The problem that the precision of the assembly surface depth of the product to be detected is low and the detection tool is inconvenient to use is solved.

[0030] More specifically, in one embodiment of the application, a containing groove is formed in the handheld handle along the axial direction of the handheld handle. The fixed seat is coaxially fixed to the outer side of the handheld handle. The movable test plate is also coaxially arranged at one end of the handheld handle where the fixed seat is arranged, and the extension end of the movable test plate extends into the containing groove of the handheld handle. The detection end of the digital dial gauge extends into the containing groove from the other end of the length direction of the containing groove, and is connected to the extension end of the movable test plate through the reciprocating pushing piece.

[0031] The reciprocating pushing piece can be a connecting spring. The two ends of the connecting spring are respectively connected to the detection end of the digital dial gauge and the extension end of the movable test plate. The connecting spring has the property of elasticity, so that the digital dial gauge can be bounced back to the initial position after the measurement is completed, and the detection tool can be repeatedly used.

[0032] Further, the reciprocating pusher further comprises a push mounting rod 15, the push mounting rod 15 is slidingly arranged in the accommodating groove, a digital gauge mounting groove 151 is formed on one end of the push mounting rod 15 towards the digital dial gauge 12, so that the digital dial gauge 12 can be more stably fixed on the push mounting rod 15, and a test end mounting groove 152 is formed on one end of the push mounting rod 15 towards the movable test plate 13, so that the extended end of the movable test plate 13 can be more stably fixed on the push mounting rod 15. The connecting spring 14 is sleeved on the push mounting rod 15, and one end of the connecting spring 14 is connected to the other end of the accommodating groove and the push mounting rod 15. In an embodiment of the present application, the connecting spring 14 is specifically a compression spring, when the operator pushes the digital dial gauge 12, the push mounting rod 15 slides in the accommodating groove towards the end away from the digital dial gauge 12, the connecting spring 14 is compressed by the pushing, and the connecting spring 14 cannot continue to be compressed when it is compressed to the compression limit, thereby pushing the movable test plate 13 to move towards the inside of the product to be tested 2. When the operator completes the measurement, the connecting spring 14 returns to the initial state and drives the push mounting rod 15 to return to the initial position, thereby making the movable test plate 13 return to the initial position, so as to facilitate the operator to perform the next depth measurement of the assembly surface of the product to be tested 2, the structure is simple and convenient to use. In other embodiments, the connecting spring 14 can also be a tension spring, and the type of the connecting spring 14 can be flexibly replaced according to actual needs.

[0033] Further, in an embodiment of the present application, when the handheld handle 1, the fixed seat 11 and the movable test plate 13 are made of rigid alloy materials, such as stainless steel, aluminum alloy and the like, all of which have the advantages of good strength and corrosion resistance. Among them, stainless steel is known for its excellent strength and corrosion resistance, and can maintain structural integrity and functional stability for a long time in harsh environments, which is particularly important for detection tools that need to frequently contact corrosive substances or be used in humid and dusty environments. Aluminum alloy has the advantages of light weight, high strength, good thermal conductivity and oxidation resistance, which can not only reduce the weight of the entire detection tool and facilitate the operator to hold it for a long time, but also effectively resist material deformation caused by temperature changes to ensure the accuracy of the test.

[0034] In actual production, the choice of stainless steel or aluminum alloy is not only to meet the basic strength and durability requirements of the handheld handle 1, the fixed seat 11 and the movable test plate 13, but also to customize the design according to the actual application scene. For example, in the factory environment where higher strength support and more stringent corrosion resistance are required, stainless steel may be a more suitable choice for the production of handheld handle 1, fixed seat 11 and movable test plate 13, because it can maintain the stability of material performance under extreme conditions. On the contrary, if the operator needs to move the handheld detection tool frequently, reducing weight to improve operational flexibility becomes the primary consideration, and aluminum alloy is more ideal because of its lighter mass density and sufficient mechanical strength.

[0035] In addition, the selection of specific materials also needs to consider factors such as cost-effectiveness, ease of processing, and environmental protection requirements. Although stainless steel has excellent performance, it is relatively high in cost and the processing process may be more complex; while aluminum alloy is relatively economical and easy to process, at the same time it meets the environmental protection concept of sustainable development. Therefore, when deciding which rigid alloy material to use, all factors must be fully evaluated to ensure that the selected material can not only meet the functional requirements of the tooling, but also meet the cost-effectiveness and environmental protection standards.

[0036] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. Unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be broadly understood, for example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements.
