Description

Technical Field

[0001] This utility model relates to the field of gear hardness measurement technology, and in particular to a gear hardness measuring device. Background Technology

[0002] In modern industry, gears, as core components of mechanical transmission systems, directly affect transmission efficiency, wear resistance, and service life, thus impacting the overall performance and reliability of mechanical equipment. As manufacturing moves towards higher precision and intelligence, industries such as aerospace, automotive manufacturing, and energy equipment are placing increasingly stringent demands on gear quality, highlighting the limitations of traditional measurement methods in terms of efficiency, accuracy, and non-destructive testing.

[0003] In the existing technology, the gear hardness measuring device is placed directly on the table during use. However, simply placing it on the table may result in accidental movement or shaking during use, leading to inaccurate measurements or operational errors. This has significant limitations and poor practicality. Utility Model Content

[0004] This utility model mainly provides a gear hardness measuring device that can fix the position of the main body of the measuring device at a fixed point.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gear hardness measuring device, comprising a measuring device body, a base fixed on the inner bottom wall of the measuring device body, a rotating block rotatably connected to the top of the base, a stud internally threaded to the rotating block, a connecting column fixed to the top of the stud, a placement plate fixed to the top of the connecting column, a limiting block fixed on the inner bottom wall of the measuring device body, a limiting groove matching the limiting block being formed in both the connecting column and the stud, a housing installed at one end of the measuring device body, a clamping plate provided below the housing, and a drive structure for driving the clamping plate to move up and down inside the housing.

[0006] Preferably, the drive structure includes a motor located at the top of the chassis. The output end of the motor passes through the inner top wall of the chassis and is fixed with a screw. A movable plate is threaded onto the outer wall of the screw. A limit post is slidably connected to the end of the movable plate away from the screw. A connecting block is fixed to the bottom end of the movable plate. The bottom end of the connecting block passes through the chassis and is fixed to a clamping plate. By running the motor, the screw rotates, causing the movable plate to move up and down under the limit of the limit post, thereby driving the clamping plate connected to the connecting block to move up and down. When it is necessary to install the main body of the measuring device, simply place the edge of the table between the main body of the measuring device and the clamping plate. By moving the clamping plate upward, in conjunction with the bottom end of the main body of the measuring device, the main body of the measuring device is clamped and fixed, thus clamping and fixing it on the tabletop, preventing accidental movement during use, and improving stability.

[0007] Preferably, the top of the limiting block passes through the base and the rotating block and is inserted into the stud and the connecting post. The base has an opening that matches the stud. Multiple handles are fixed on the outer wall of the rotating block. The opening allows the base to have an opening for the stud to move up and down. The handles make it easy for the user to rotate the rotating block.

[0008] Preferably, the bottom end of the screw is rotatably connected to the housing, and both ends of the limiting post are fixed to the housing. By rotatably connecting the bottom end of the screw to the housing, both ends of the screw have a point of force, making its operation more stable.

[0009] Preferably, a mounting bracket is fixed to the top of the chassis, and the motor is mounted on the end of the mounting bracket facing the chassis. The mounting bracket provides a mounting point for the motor, making its operation more stable.

[0010] Preferably, mounting plates are fixed at both ends of the chassis, and both mounting plates are fixed to the main body of the measuring device by bolts. By setting the mounting plates and bolts, the chassis can be installed and disassembled as a whole, so that the chassis can be installed or not according to actual needs.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the operation of the motor drives the screw to rotate, causing the moving plate to move up and down under the limit of the limiting post. This, in turn, drives the clamping plate connected to the connecting block to move up and down. When it is necessary to install the main body of the measuring device, simply place the edge of the table between the main body of the measuring device and the clamping plate. By moving the clamping plate upward, in conjunction with the bottom end of the main body of the measuring device, the main body of the measuring device is clamped and fixed, thus securing it to the tabletop and preventing accidental movement during use, resulting in greater stability.

Detailed Implementation

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Please see Figures 1-4This utility model provides a technical solution: a gear hardness measuring device, including a measuring device body 1, a base 2 fixed on the inner bottom wall of the measuring device body 1, a rotating block 3 rotatably connected to the top of the base 2, a stud 5 internally threaded onto the rotating block 3, a connecting post 6 fixed to the top of the stud 5, a placement plate 7 fixed to the top of the connecting post 6, a limiting block 8 fixed on the inner bottom wall of the measuring device body 1, and a limiting groove 9 matching the limiting block 8 being formed in both the connecting post 6 and the stud 5. A housing 11 is installed at one end of the measuring device body 1, a clamping plate 12 is provided below the housing 11, and a drive structure 13 for driving the clamping plate 12 to move up and down is provided inside the housing 11. In use, the gear to be measured is placed on the placement plate 7, so that the edge of the gear being measured is aligned with the output end of the measuring device body 1. By rotating the rotating block 3, the connecting column 6 and the stud 5 rise under the limit of the limiting block 8 and the limiting groove 9, so that the gear on the placement plate 7 abuts against the output end of the measuring device body 1. At this time, by controlling the measuring device body 1, the output end of the measuring device body 1 applies pressure to the measuring device, and the measurement status is displayed on the display screen built into the measuring device body 1, thus achieving the measurement effect. Through the operation of the drive structure 13, the clamping plate 12 can be driven to rise and fall as a whole. When it is necessary to install the measuring device body 1, simply place the edge of the table between the measuring device body 1 and the clamping plate 12. By moving the clamping plate 12 upward, in conjunction with the bottom end of the measuring device body 1, the measuring device body 1 is clamped and fixed, so that it is clamped and installed on the tabletop, avoiding accidental movement during use and making it more stable.

[0017] like Figure 1-4 As shown, the drive structure 13 includes a motor 1301 located at the top of the housing 11. The output end of the motor 1301 penetrates the inner top wall of the housing 11 and is fixed with a screw 1302. A movable plate 1303 is threaded onto the outer wall of the screw 1302. A limit post 1304 is slidably connected to one end of the movable plate 1303 away from the screw 1302. A connecting block 1305 is fixed to the bottom end of the movable plate 1303. The bottom end of the connecting block 1305 penetrates the housing 11 and is fixed to the clamping plate 12. The operation of the motor 1301 drives the screw... Rotation of 1302 causes the moving plate 1303 to move up and down under the limit of the limiting post 1304, thereby driving the clamping plate 12 connected to the connecting block 1305 to move up and down. When it is necessary to install the measuring device body 1, simply place the edge of the table between the measuring device body 1 and the clamping plate 12. By moving the clamping plate 12 upward, in conjunction with the bottom end of the measuring device body 1, the measuring device body 1 is clamped and fixed, so that it is clamped and installed on the tabletop, avoiding accidental movement during use and making it more stable.

[0018] like Figure 1-4As shown, the top of the limiting block 8 passes through the base 2 and the rotating block 3 and is inserted into the stud 5 and the connecting post 6. The base 2 has an opening 10 that matches the stud 5. Multiple handles 4 are fixed on the outer wall of the rotating block 3. The opening 10 allows the base 2 to have an opening 10 for the stud 5 to move up and down. The handles 4 make it easy for the user to rotate the rotating block 3.

[0019] like Figure 1-4 As shown, the bottom end of the screw 1302 is rotatably connected to the housing 11, and both ends of the limiting post 1304 are fixed to the housing 11. By rotatably connecting the bottom end of the screw 1302 to the housing 11, both ends of the screw 1302 have a point of force, making its operation more stable.

[0020] like Figure 1-4 As shown, a mounting bracket 14 is fixed to the top of the chassis 11. The motor 1301 is mounted on the end of the mounting bracket 14 facing the chassis 11. The mounting bracket 14 provides a mounting point for the motor 1301, making its operation more stable.

[0021] like Figure 1-4 As shown, mounting plates 15 are fixed at both ends of the chassis 11. Both mounting plates 15 are fixed to the main body 1 of the measuring device by bolts 16. With the mounting plates 15 and bolts 16, the chassis 11 can be installed and disassembled as a whole, so that the chassis 11 can be installed or not according to actual needs.

[0022] The usage and working principle of this device are as follows: When using the device, place the gear to be measured onto the placement plate 7, aligning the edge of the gear with the output end of the measuring device body 1. Then, by rotating the rotating block 3, the connecting column 6 and the stud 5 rise under the limiting blocks 8 and 9, causing the gear on the placement plate 7 to abut against the output end of the measuring device body 1. At this point, by controlling the measuring device body 1, pressure is applied to the gear at its output end. The measurement results are displayed on the screen built into the measuring device body 1, achieving the measurement effect. (The last sentence appears to be incomplete and possibly refers to a different device.) The operation of the machine 1301 drives the screw 1302 to rotate, causing the moving plate 1303 to move up and down under the limit of the limiting post 1304. This, in turn, drives the clamping plate 12 connected to the connecting block 1305 to move up and down. When it is necessary to install the measuring device body 1, simply place the edge of the table between the measuring device body 1 and the clamping plate 12. By moving the clamping plate 12 upward, in conjunction with the bottom end of the measuring device body 1, the measuring device body 1 is clamped and fixed, thus securing it on the tabletop and preventing accidental movement during use, resulting in greater stability.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
