Description

Technical Field

[0001] This utility model belongs to the field of composite material machining technology, specifically relating to an automatic traction device for grinding the thickness of thin-walled composite structural parts. Background Technology

[0002] The base strip structural components in the radome use composite blanks with uneven thickness during the forming process, requiring grinding to correct the thickness. Traditionally, the base strip is manually pulled forward to achieve the desired thickness across the entire surface. However, this manual pulling results in uneven traction, making it impossible to guarantee uniform movement and causing surface ripples. Consequently, the thickness may not meet requirements, leading to low processing yield and efficiency. Utility Model Content

[0003] This invention addresses the problem of uneven traction force and inconsistent speed movement of base plates caused by manual pulling, resulting in wavy surfaces on the base plates. It provides an automatic traction device that can replace manual traction in base plate grinding. This device achieves uniform speed movement during the base plate thickness grinding process, ensuring the accuracy of base plate thickness processing, improving the pass rate of base plate thickness processing, and reducing the cost of base plate manufacturing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automatic traction device for thickness grinding of thin-walled composite structural parts, comprising: The drive mechanism provides driving force for the entire device; The transmission mechanism, mounted on the base, has two meshing gears and two mounting shafts; The traction mechanism has two opposing rollers, which are fixedly connected to the mounting shaft, and there is a certain gap between the two rollers.

[0005] As a further embodiment of this utility model: the transmission mechanism includes a fixed part and a movable part. The fixed part includes a first gear and a first mounting shaft. The first mounting shaft is mounted on the base through a bearing. One end of the first mounting shaft is fixedly connected to the output end of the drive mechanism, and the other end is interference-fitted with the first gear. The movable part includes a mounting seat, a second gear, and a second mounting shaft. The mounting seat and the base form a slider-rail mechanism. The second mounting shaft is mounted on the mounting seat through a bearing and is interference-fitted with the second gear.

[0006] As a further embodiment of this utility model, it also includes an adjustment mechanism, which has a screw, a pressure ring and a spring. The screw is threaded into the base, one end of the pressure ring is connected to the screw and the other end is connected to the mounting base, and the spring is sleeved on the pressure ring.

[0007] As a further embodiment of this utility model: at least two fixing nuts are provided on the base, and the screw is threadedly engaged with the fixing nuts.

[0008] As a further embodiment of this utility model, the two ends of the spring abut against the base and the mounting seat respectively, providing elastic force.

[0009] As a further embodiment of this utility model, knurling is provided on the outer surface of the roller.

[0010] As a further embodiment of this utility model: the drive mechanism includes a distribution box and a geared motor connected to each other, the distribution box includes a transformer, a leakage current protector and a speed regulator, and the output end of the geared motor is connected to a first mounting shaft.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: 1. This application effectively solves the problems of ripple phenomenon and uneven thickness in the base plate thickness grinding process.

[0012] 2. This application features a simple structure, is easy to operate and disassemble, and provides valuable reference for similar thickness grinding processes in the future. It has achieved excellent quality and economic benefits.

[0013] 3. The structure of this application mainly consists of a transformer, speed controller, geared motor, gears, and rollers. This automatic traction device inserts one end of the base strip blank between two rollers, and adjusts the clamping force of the rollers on the base strip using screws and pressure rings. The transformer adjusts the voltage to 36V, driving the geared motor. The driving force of the drive mechanism comes from the geared motor, which drives the gears, which in turn drive the rollers through bearings. The traction force is provided by the friction of the rollers. This achieves uniform grinding motion of the base strip. It solves the problems of uneven traction force and inconsistent speed during the grinding process caused by manual traction of the base strip, resulting in ripples on the base strip surface. It also ensures uniform base strip thickness and improves the processing qualification rate.

[0014] 4. This application uses an adjustment mechanism to move the movable part, changing the gap between the two rollers to accommodate base strips of different thicknesses. The spring allows for elastic adjustment of the gap, thereby increasing friction and improving the traction of the base strip. Attached Figure Description
