Description

Technical Field

[0001] This utility model mainly relates to the field of gear inspection technology, specifically a gear pitch outer diameter inspection fixture. Background Technology

[0002] Gears are a common mechanical transmission element used to transmit power and motion. They achieve rotational motion and torque transmission between two or more shafts through the meshing of teeth.

[0003] Gears, as a common mechanical transmission component, often exhibit a certain degree of complexity in shape and structure. In some cases, the design and manufacture of gears may require meeting very specific requirements, resulting in their shape and dimensions exceeding the conventional standard range. Due to their irregular shape, conventional measurement methods cannot be directly applied to the measurement of gear pitch and outer diameter. Utility Model Content

[0004] This utility model mainly provides a gear pitch outer diameter inspection fixture to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A gear pitch outer diameter gauge tooling includes a mounting plate, the surface of which has three sliding grooves, and positioning components are assembled inside the sliding grooves. Fixing components are connected to the ends of the three sliding grooves of the mounting plate.

[0007] Preferably, the positioning component includes a positioning block, a spring, a fixing block, and a first connecting groove. The positioning block is assembled inside the groove via a slide rail, and one end of the positioning block is fixedly connected to a spring, and one end of the spring is fixedly connected to a fixing block. The fixing block is assembled inside the groove via a slide rail, and one end of the fixing block has a first connecting groove.

[0008] Preferably, the fixing component includes a baffle, a first fixing groove, a second connecting groove, and a second fixing groove. The mounting plate is connected to a baffle at each of the three sliding groove ends, and the baffle has a first fixing groove on both sides. The baffle has a second connecting groove between two first fixing grooves.

[0009] The mounting plate has a second fixing groove on both sides of the end of the slide.

[0010] Preferably, the three grooves are evenly distributed on the surface of the mounting plate, and the length direction of the grooves is arranged radially with respect to the center point of the mounting plate.

[0011] Preferably, the dimensions of the first connecting groove match the dimensions of the second connecting groove, for connecting the fixing block to the baffle by bolts.

[0012] Preferably, the dimensions of the first fixing groove match the dimensions of the second fixing groove, for connecting the mounting plate and the baffle by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By placing the gear on three positioning blocks and utilizing the elastic buffering effect of the springs, not only can the impact force generated when the gear is placed be effectively absorbed, but the relative position between the positioning blocks and the fixed blocks can also be ensured to be stable. In the scenario of measuring irregular gears, the diameter of the center circle of the positioning block can be accurately measured by a two-dimensional measuring device, thereby indirectly obtaining the outer diameter of the gear pitch.

[0015] 2. The baffle is fixed to one side of the mounting plate by bolts passing through the first fixing groove and the second fixing groove. The fixing block is fixedly connected to the baffle by bolts passing through the first connecting groove, the second connecting groove and the baffle. According to the shape of the gear, the positioning block and the fixing block are selected to achieve quick installation, fixing and disassembly.

[0021] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0022] Please refer to the appendix carefully. Figure 1-3A gear pitch outer diameter inspection fixture includes a mounting plate 1. Three grooves 2 are evenly distributed on the surface of the mounting plate 1, and their length direction is radially arranged with respect to the center point of the mounting plate 1. This arrangement better accommodates the inspection needs of gears of different sizes. A positioning component 3 is installed inside each groove 2. The positioning component 3 includes a positioning block 301, a spring 302, a fixing block 303, and a first connecting groove 304. The positioning block 301 is mounted inside the groove 2 via a slide rail. One end of the positioning block 301 is fixedly connected to the spring 302, while the other end of the spring 302 is fixedly connected to the fixing block 303. The fixing block 303 is also mounted inside the groove 2 via a slide rail, ensuring its stability and mobility within the groove. One end of the fixing block 303 has a first connecting groove 304, facilitating subsequent connections. The mounting plate 1 is connected to the end of each of the three grooves 2. A fixing component 4 is provided, which includes a baffle 401, a first fixing groove 402, a second connecting groove 403, and a second fixing groove 404. The mounting plate 1 is connected to the baffle 401 at each end of the three sliding grooves 2. The baffle 401 has a first fixing groove 402 on both sides. Between two first fixing grooves 402, the baffle 401 also has a second connecting groove 403. The mounting plate 1 has a second fixing groove 404 on both sides of the end of the sliding groove 2. The size of the first connecting groove 304 matches the size of the second connecting groove 403, so that the two can be connected by bolts, thereby tightly connecting the fixing block 303 and the baffle 401 together. The size of the first fixing groove 402 matches the size of the second fixing groove 404, so that the two can be firmly connected to the mounting plate 1 and the baffle 401 by bolts, ensuring the stability and reliability of the entire device during use.

[0023] The specific operation method of this utility model is as follows:

[0024] The gear is placed on three positioning blocks 301, which are mounted on the mounting plate 1 via slide rails. The positioning blocks 301 and the fixed blocks 303 are connected by springs 302. The elasticity of the springs 302 can buffer the impact force generated when the gear is placed to a certain extent, and also ensure the relative position stability between the positioning blocks 301 and the fixed blocks 303. The fixed blocks 303 are also mounted on the mounting plate 1 via slide rails. The baffle 401 is fixed to one side of the mounting plate 1 by bolts passing through the first fixed groove 402 and the second fixed groove 404. The fixed blocks 303 are fixedly connected to the second fixed groove and the baffle 401 by bolts passing through the first connecting groove 304, so as to avoid displacement during inspection and inaccurate measurement results. The diameter of the center circle of the three positioning blocks 301 is measured by a two-dimensional measuring instrument to achieve the purpose of inspecting the pitch outer diameter.

[0025] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
