Abstract
Description
Technical Field
[0001] This utility model specifically relates to a tooling for three-dimensional inspection of parts, belonging to the field of mechanical inspection technology. Background Technology
[0002] Parts specifically refer to independent, single objects used in the mechanical manufacturing field for assembling into machines. Their definition encompasses three dimensions: structurally, they are indivisible basic units; functionally, they serve as the foundation for components and the entire machine; and in the manufacturing process, production can be completed without additional assembly steps. Depending on the application, they can be categorized into bearing components such as bushings and bearing shells, fastening elements such as nuts and bolts, and transmission components such as crankshafts and gears.
[0003] In the three-dimensional dimension inspection of mechanical parts, tooling is used to fix and position the parts to ensure the accuracy of the inspection. However, the existing tooling has poor versatility and is often only suitable for one or a few sizes and shapes of parts. When inspecting different parts, the tooling needs to be changed, which increases costs and reduces efficiency. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a tooling for three-dimensional inspection of parts, including a mounting frame. The outer surface of the mounting frame has two mounting holes of the same size. A fixing component is installed inside the mounting frame. The fixing component includes a motor mounted on the outer surface of the mounting frame. A lead screw is fixedly connected to the output end of the motor, and the end of the lead screw away from the motor is rotatably connected to the outer surface of the mounting frame. Two movable plates are threadedly connected to the outer surface of the lead screw. Movable frames are fixedly connected to the upper surfaces of both movable plates, and the movable frames are slidably connected to the outer surface of the mounting frame. An inspection mechanism for inspecting parts is mounted on the outer surface of the mounting frame.
[0005] Furthermore, the fixing component also includes two sets of grooves formed on the outer surface of the mounting frame, each set of grooves having a sliding rod slidably connected inside, and the other end of the sliding rod being connected to the inner wall of the movable frame.
[0006] Furthermore, a set of pressure rods is slidably connected to the outer surfaces of both movable frames, and a circular plate is fixedly connected to the ends of the two sets of pressure rods that are far apart from each other, and a spring is installed between the circular plate and the movable frame.
[0007] Furthermore, a limiting plate is fixedly connected to the outer surface of each of the pressing rods, and a clamping pad is fixedly connected to the end of each of the two sets of pressing rods that are close to each other.
[0008] Furthermore, each of the clamping pads is made of rubber, and the clamping pads are located above the lead screw.
[0009] Beneficial effects:
[0010] By using a mounting bracket and a fixing component, the fixing component can fix parts of different sizes and shapes, so that tooling does not need to be changed during inspection, thereby reducing costs and improving the efficiency of processing parts.
[0011] The starting motor is set up by cooperating with a motor, lead screw, moving plate, moving frame, groove, slide rod, pressure rod, circular plate, spring, limiting plate, and clamping pads. Its output end drives the lead screw to rotate. The distance between the two moving frames can be adjusted by the engagement of the lead screw and the moving plate. When the two clamping pads contact the part, the spring is pulled open, and the pressure rod slides accordingly. The limiting plate restricts the movement range of the pressure rod, ultimately fixing the part. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3 As shown, a tooling for three-dimensional inspection of a part includes a mounting frame 1. The outer surface of the mounting frame 1 has two mounting holes 2 of the same size. The mounting holes 2 can be used to install bolts, thereby fixing the mounting frame 1 and ensuring its normal use in the future.
[0018] The mounting bracket 1 has a fixing component 3 installed inside. The fixing component 3 includes a motor 301 installed on the outer surface of the mounting bracket 1. The output end of the motor 301 is fixedly connected to a lead screw 302, and the end of the lead screw 302 away from the motor 301 is rotatably connected to the outer surface of the mounting bracket 1. After the motor 301 is started, it can drive the lead screw 302 to rotate. The rotatable connection design between the lead screw 302 and the mounting bracket 1 can effectively ensure the stability and smoothness of the subsequent rotation of the lead screw 302.
[0019] The outer surface of the lead screw 302 is threadedly connected to two moving plates 303. The lead screw 302 and the moving plates 303 are connected by a threaded design, which can precisely adjust the distance between the moving plates 303 and provide a reliable guarantee for the stable operation of the subsequent device.
[0020] The upper surfaces of the two movable plates 303 are fixedly connected with movable frames 304, and the movable frames 304 are slidably connected to the outer surface of the mounting frame 1. The movable frames 304 and the mounting frame 1 adopt a sliding connection design, which can effectively guide the movement of the movable frames 304, thereby ensuring the stability and accuracy of the subsequent movement of the movable frames 304.
[0021] The fixing component 3 also includes two sets of grooves 305 formed on the outer surface of the mounting bracket 1. Each set of grooves 305 has a sliding rod 306 slidably connected inside, and the other end of the sliding rod 306 is connected to the inner wall of the moving frame 304. Through the sliding connection between the grooves 305 and the sliding rod 306, the movement of the moving frame 304 can be guided to a certain extent, thereby ensuring the subsequent use effect of the moving frame 304.
[0022] A set of holding rods 307 are slidably connected to the outer surfaces of the two movable frames 304. A circular plate 308 is fixedly connected to the ends of the two sets of holding rods 307 that are far apart from each other. A spring 309 is installed between the circular plate 308 and the movable frame 304. The spring 309 can provide a certain reset capability for the holding rods 307, thereby facilitating subsequent fixing work.
[0023] Each pressure rod 307 has a limiting plate 310 fixedly connected to its outer surface. The limiting plate 310 can effectively limit the movement of the pressure rod 307, thereby ensuring the reliability of the pressure rod 307 in subsequent use.
[0024] Each of the two sets of clamping rods 307 has a clamping pad 311 fixedly connected to one end of each other. Each clamping pad 311 is made of rubber and is located above the lead screw 302. The clamping pads 311 ensure the effectiveness of clamping parts, thus facilitating subsequent testing.
[0025] The outer surface of the mounting bracket 1 is equipped with a detection mechanism 4 for inspecting parts. The detection mechanism 4 can detect the fixed parts, thereby ensuring that the parts can be used in subsequent processes.
[0026] As a technical optimization of this utility model, when inspecting the parts, the motor 301 is first started, and the output end of the motor 301 drives the lead screw 302 to rotate. Then, by using the meshing between the lead screw 302 and the moving plate 303, the distance between the two moving frames 304 can be adjusted. When the two clamping pads 311 move to contact the parts, the spring 309 will be pulled open. During the process, the holding rod 307 will slide. Then, the limiting plate 310 limits the holding rod 307, and the movement of the holding rod 307 to a certain range will be restricted, thereby realizing the fixing of the parts. Finally, the inspection mechanism 4 is started to start the processing of the parts.
