Description

Technical Field

[0001] This utility model relates to the field of handle screw technology, and in particular to a detection device for handle screws. Background Technology

[0002] A handle screw is a screw mechanical component with a handle, mainly used for manual adjustment or fixing. It combines the linear motion characteristics of a screw with the ease of operation of a handle. It consists of two parts: a screw and a handle (rotating handle). Rotating the handle drives the screw to rotate. The outer diameter of the thread is a key dimension for the fit between the screw and the nut / threaded hole. Inspecting the outer diameter can prevent the assembly from being too tight (jammed) or too loose (loose). When inspecting the outer diameter of a handle screw, a testing device is used to measure the outer diameter of the screw.

[0003] The detection devices for handle screws in the existing technology have the following drawbacks in actual use: When inspecting the handle screw, it is necessary to position the handle screw. The existing handle screw inspection devices have a complicated and time-consuming operation process for positioning the handle screw, which reduces the overall efficiency of handle screw inspection and is inconvenient for inspecting handle screws of different diameters and lengths. Utility Model Content

[0004] In view of the existing technology, the positioning of the handle screw is required when testing the handle screw. The operation process of positioning the handle screw in the existing handle screw testing device is relatively complicated and time-consuming, which reduces the overall efficiency of handle screw testing and is inconvenient for testing handle screws of different diameters and lengths. This utility model provides a testing device for handle screws.

[0005] The technical solution adopted by this utility model is: a detection device for a handle screw, including a detection platform, a positioning component on the top of the detection platform, the positioning component including a positioning box, a positioning block, a sliding groove, a cylinder, and a mounting base, one of the mounting bases being fixedly mounted on the outer wall of the top of the detection platform, and the other mounting base being slidably connected to the top of the detection platform, one end of the positioning block being provided with a moving block located inside the positioning box, a guide rod being provided on the inner wall of the positioning box, and the moving block being slidably sleeved on the outside of the guide rod, a spring being provided on the inner wall of the positioning box and connected to the moving block, the positioning block being fixedly mounted on the outer wall of the positioning box, the cylinder being fixedly mounted on the outer wall of the positioning box, and the cylinder being slidably sleeved on the outer wall of the positioning box.

A cylinder is fixedly installed on the outer wall of the testing platform, and the slider is installed on the output end of the cylinder.

[0006] Furthermore, a detection assembly is provided on the top of the detection platform, the detection assembly including a movable frame, a top holding plate, a limiting groove and a cylinder.

[0007] Furthermore, the movable frame has an internal cavity, and a compression plate is slidably connected inside the cavity.

[0008] Furthermore, the outer wall of the extrusion plate is provided with a connecting block that is connected to the top holding plate, the outer wall of the extrusion plate is provided with an infrared ranging receiver, and the inner wall of the moving frame is provided with an infrared ranging transmitter.

[0019] In order to solve the problems existing in the background art, this application proposes the following technical solution: a detection device for a handle screw.

[0020] The specific technical solution includes a testing platform 1, with a positioning assembly 2 on its top. The positioning assembly 2 includes a positioning box 201, a positioning block 203, a slide groove 211, a cylinder 212, and a mounting base 213. One mounting base 213 is fixedly mounted on the outer wall of the top of the testing platform 1, and the other mounting base 213 is slidably connected to the top of the testing platform 1. One end of the positioning block 203 has a moving block 202 located inside the positioning box 201. A guide rod 204 is provided on the inner wall of the positioning box 201, and the moving block 202 is slidably sleeved on the outside of the guide rod 204. A spring 205 connected to the moving block 202 is provided on the inner wall of the positioning box 201. A translation plate 206 is provided inside the positioning box 201, and a pressing block 207 is fixedly mounted on the outer wall of the translation plate 206. Threads are threaded onto the outer wall of the positioning box 201.

A cylinder 212 is fixedly installed on the outer wall of the testing table 1, and the slider 210 is provided on the output end of the cylinder 212. The positioning component 2 can fix the handle screw at multiple points simultaneously, making the positioning process of the handle screw more convenient and efficient. It can also fix handle screws of different diameters and lengths, making it more widely applicable.

[0021] In specific implementations, such as Figure 1 , 3 and Figure 4As shown, a detection component 3 is provided on the top of the detection table 1. The detection component 3 includes a moving frame 301, a top holding plate 304, a limiting groove 310, and a cylinder 312. The detection component 3 is used to detect whether the outer diameter of the handle screw is too large or too small.

[0022] Furthermore, the movable frame 301 has a cavity 302 inside, and a compression plate 303 is slidably connected inside the cavity 302.

[0023] Furthermore, the outer wall of the extrusion plate 303 is provided with a connecting block 305 connected to the top holding plate 304, the outer wall of the extrusion plate 303 is provided with an infrared ranging receiver 309, and the inner wall of the moving frame 301 is provided with an infrared ranging transmitter 308. The infrared ranging receiver 309 receives the signal emitted by the infrared ranging transmitter 308 and can detect the distance between the two, thereby detecting whether the outer diameter of the handle screw is too large or too small.

[0024] Furthermore, an anti-deviation rod 306 is fixedly installed inside the cavity 302, and the extrusion plate 303 is slidably sleeved on the outside of the anti-deviation rod 306. A second spring 307 connected to the extrusion plate 303 is provided on the inner wall of the cavity 302.

The control mechanism 4 is used for signal processing, data display or control of cylinder 212, motor 214, infrared ranging transmitter 308, infrared ranging receiver 309 and cylinder 312.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: In use, the end of the handle screw with the handle is inserted between multiple positioning blocks 203 of the positioning component 2 fixed on the testing table 1, and the handle passes between two positioning blocks 203. Activating cylinder 212 moves the slider 210 and mounting base 213 of one of the positioning components 2, allowing the positioning component 2 sliding on the testing table 1 to move towards the other positioning component 2. The multiple positioning blocks 203 of the positioning component 2 sliding on the testing table 1 surround the end of the handle screw without the handle. Rotating the pressing screw 208 moves the translation plate 206, which in turn moves the pressing block 207 to press against the inclined surface of the moving block 202. This allows the moving block 202 to synchronously move the positioning blocks 203, enabling multiple positioning blocks 203 to move simultaneously and press and position the end of the handle screw. Through the two positioning components 2, multiple points at both ends of the handle screw can be positioned. The positioning and operation process is very convenient, which can shorten the operation time and improve the overall efficiency of handle screw detection. It can also make the handle screw positioning more stable and can position handle screws of different diameters and lengths, making it more widely applicable. When the motor 214 is turned on, the positioning box 201 rotates, which in turn drives the handle screw to rotate. The outer diameter of the handle screw will be held against the top plate 304. If the outer diameter of the handle screw is too large or too small, the top plate 304 will move, and the distance measured in real time by the infrared ranging transmitter 308 and the infrared ranging receiver 309 will change, thus detecting whether the outer diameter of the handle screw at that point is too large or too small. When the cylinder 312 is turned on, the limit block 311 moves, which in turn drives the moving frame 301 to move. It can detect the outer diameter of the handle screw at different positions, making it very convenient to use.
