Description

Technical Field

[0001] The utility model relates to the technical field of radar housing processing, in particular to a radar housing scratch-resistant test mechanism. Background Technique

[0002] Radar metal housings play a crucial role in radar systems. They are not only the first line of defense to protect sensitive internal electronic components of the radar from external environmental factors but also need to meet specific electrical and mechanical performance requirements. Radar housings are widely used in multiple fields such as military, civil aviation, meteorological monitoring, traffic monitoring, security systems, and industrial automation. Their design and manufacturing need to strictly comply with relevant industry standards and specifications.

[0003] The scratch test of the radar housing is an important test to evaluate the surface wear resistance and scratch resistance of the housing material and its coating. This test is usually carried out during the new product development stage to ensure that the housing and its coating will not be easily damaged in the expected use environment and maintain their functionality and appearance.

[0004] When the existing scratch test device is in use, it usually only has the test function for one type of scratch head and cannot test scratch heads of multiple materials in one test. When it is necessary to test scratch heads of other materials, the staff needs to remove the scratch assembly, then replace the scratch head of a different material, and then reassemble the scratch assembly. This not only makes the operation process cumbersome but also reduces the test efficiency. Therefore, in order to solve the above-mentioned technical problems, a radar housing scratch-resistant test mechanism is proposed. Content of the Utility Model

[0005] The purpose of the utility model is achieved in the following way: A radar housing scratch-resistant test mechanism includes a mounting frame, a scratch assembly, and a placement assembly. The scratch assembly is installed at the upper end of the mounting frame, and the placement assembly is arranged at the lower end of the mounting frame. The scratch assembly includes a transfer disk and a driving motor. The transfer disk is rotatably arranged in the middle of the mounting frame through an inclined shaft. The top surface of the inclined shaft is a horizontal plane, and the bottom surface of the inclined shaft is an inclined surface. The top surface of the transfer disk is in contact with the bottom surface of the inclined shaft. The bottom surface of the transfer disk is evenly and obliquely distributed with a first chuck, a second chuck, and a third chuck. The first chuck, the second chuck, and the third chuck are provided with a plurality of positioning ball heads on the transfer disk. The positioning ball heads are distributed between the bottom surface of the inclined shaft and the top surface of the transfer disk. An installation groove is provided at a position on the top surface of the transfer disk close to the positioning ball heads. A return spring is arranged in the installation groove and is connected to the positioning ball head. A positioning groove is opened at a position on the bottom surface of the inclined shaft close to the installation groove. A part of the positioning ball head protrudes out of the installation groove. The top surface of the transfer disk is connected to the bottom surface of the inclined shaft through a rotating shaft. Threaded holes are evenly distributed at positions on the bottom surface of the transfer disk close to the first chuck, the second chuck, and the third chuck; among them, the first chuck is perpendicular to the magnetic suction seat.

[0006] In the above description, for a further solution, the drive motor is installed at both ends of the top surface of the mounting frame. Screws are provided at positions on both ends of the mounting frame close to the drive motor. The upper ends of the screws pass through the mounting frame and are connected to the drive motor, and the lower ends of the screws are rotatably connected to the lower ends of the mounting frame. A scale column is provided on one side of the screw. The screw is used to drive the transfer plate to move up and down, and the scale column is used to display the thickness of the outer shell and the moving distance of the transfer plate.

[0007] In the above description, for a further solution, a connection block is installed on the top surface of the inclined shaft. One side of the connection block is connected to a connecting plate. The connecting plate is movably connected to the screw through a connecting rod and a movable plate. An installation sleeve matching the connecting rod is provided on the side of the connecting plate away from the connection block. The installation sleeve is fixedly connected to the connecting rod. The two ends of the connecting rod extend towards the screw. The movable plate is fixed at the two ends of the connecting rod and is threadedly connected to the screw. The movable plate is used to be connected to the screw to provide the effect of moving up and down.

[0008] In the above description, for a further solution, the placing assembly includes a movable table, a magnetic attraction seat and a traction motor. The traction motor is arranged on one side of the lower end of the mounting frame. The movable table is movably arranged in the middle of the lower end of the mounting frame. Guide rods are installed at the lower end of the mounting frame, and the two ends of the guide rods are fixedly connected to the mounting frame. A guide sleeve matching the guide rod is provided at a position on the bottom of the movable table close to the guide rod. The magnetic attraction seat is used to place the product and magnetically attract the product at the same time to achieve the effect of fixing the product.

[0009] In the above description, for a further solution, a pulley is provided on the side of the lower end of the mounting frame away from the traction motor. The pulley is connected to the lower end of the mounting frame through a mounting block. The traction motor is connected to the pulley through a belt passing through the mounting frame.

When it is necessary to replace the scratching heads of different materials for testing, the operator only needs to turn the transfer disk. When the force is sufficient, the positioning ball head will be retracted into the installation groove. When retracting, the compression spring will contract. After a part of the positioning ball head protruding from the positioning groove is retracted into the installation groove, the transfer disk can be rotated. When the positioning ball head moves into the next positioning groove, the compression spring will reset and push a part of the positioning ball head to protrude from the installation groove, and the protruding part will enter the positioning groove, achieving the effect of positioning and fixing through the positioning groove, completing the function of replacing scratching heads of different materials. Without the need to disassemble the scratching component, a quick replacement function is provided, reducing the operation process and improving the testing efficiency.
