Technical Field

[0001] The utility model relates to the field of radar bracket welding detection, in particular to an auxiliary tool for measuring the pulling force of a radar bracket after welding. Background Art

[0002] The pull-out force verification test of the bumper assembly radar bracket after welding caused damage to the radar product. The internal organizational problem analysis confirmed that the radar was damaged by directly fixing it on the radar. It was also proposed to design and develop a special tool for measuring the radar bracket, using the tool instead of the radar to measure the pull-out force. Summary of the invention

[0003] According to the above technical problems, the purpose of the present invention is that the traditional pull-out force gauge directly acts on the radar product, causing damage to the product during the tensile test. Through the installation of this positioning module, the positioning module replaces the radar installation state, and the pull-out force gauge can be used to act on the end ring of the tool to achieve accurate measurement of the pull-out force of the radar bracket.

[0004] The utility model provides an auxiliary tool for measuring the pull-out force of a radar bracket after welding, which is characterized by comprising a positioning block, a sliding pressing block and a lifting ring, wherein a lifting ring is fixed to one end of the positioning block, a movable protrusion is arranged at the other end of the positioning block, and a sliding pressing block is movably installed on the positioning block.

[0005] A groove is provided on the positioning block, baffles are provided at both ends of the groove, a spring is installed in the groove, a movable protrusion is fixed to the front end of the spring, baffles are provided on both sides of the movable protrusion, and after installation, the baffle is located at the rear side of the baffle, and the baffle blocks the baffle to prevent the movable protrusion from falling off.

[0006] The lifting ring is provided with a fixing groove.

[0007] A latex ring is arranged between the sliding pressing block and the positioning block.

[0008] A placement groove is arranged on the inner side of the sliding pressing block.

[0009] The positioning block and the sliding pressing block are made of aluminum alloy material, and the lifting ring is a standard metal lifting ring (M5).

[0010] In order to adapt to the repeated use of pull-out force testing, the whole is made of aluminum alloy to ensure that it will not be damaged after long-term high-frequency use. In order to facilitate the use between different QC lines, the measuring tool structure is simple and easy to operate, and it is light in weight and small in size for easy carrying.

[0011] This tool is a tool for measuring the pull-out force of the radar bracket after welding. It is characterized by the fact that the measuring tool consists of a positioning block, a sliding clamping block, a lifting ring, and components. The positioning block is connected to the lifting ring, and the sliding clamping block slides on the positioning block. The positioning block is inserted into the radar bracket, and the two protrusions of the positioning block are inserted into the groove of the radar bracket. The sliding clamping block is moved to the radar bracket to clamp it, and the pull-out force gauge is hooked on the lifting ring. The vertical angle is visually adjusted and the pull-out force is measured.

[0012] The beneficial effects of the utility model are as follows: the utility model innovates the traditional pull-out force test method after parts assembly. Since the current pull-out force test method for radar brackets is to hook the radar with a pull-out force gauge for measurement, the radar product is damaged after the pull-out force of the radar bracket is tested due to insufficient product strength, resulting in cost waste. The development and use of this measuring tool solves the problem of insufficient strength of traditional measurements. Through the positioning module measurement, the measuring tool replaces the radar after installation, and accurate values ​​can be measured by the pull-out force gauge. Combined with the pull-out tolerance requirements, it is easier to judge whether the welding state of the radar bracket meets the requirements.

[0013] When the utility model is used, it can replace the actual product installation and then perform the pull-out force test. The measuring tool can directly measure the pull-out force instead of the radar installation state, realize non-damage radar products, quickly detect the pull-out force after welding, and determine whether the radar bracket welding state is qualified or not.

[0014] The positioning block is connected to the lifting ring, and the sliding clamping block slides on the positioning block. The positioning block is inserted into the radar bracket, and the two protrusions of the positioning block are inserted into the grooves of the radar bracket. The sliding clamping block moves to the radar bracket to clamp it, and the pull-out force gauge hooks the lifting ring. The vertical angle is visually adjusted and the pull-out force is measured. Through the installation of this positioning module, the measurement tool replaces the state after the radar is installed, and the accurate value can be measured by the pull-out force gauge. Combined with the tensile force tolerance requirements, it is easier to judge whether the welding state of the radar bracket meets the requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Example 1

[0023] The utility model relates to an auxiliary tool for measuring the pull-out force of a radar bracket after welding, which can conveniently install and clamp parts onto the radar bracket. The tool comprises a positioning block, a sliding pressing block and a lifting ring.

[0024] A lifting ring is fixed on one end of the positioning block to facilitate the hanging and carrying of the tool. A movable protrusion is designed on the other end of the positioning block. This innovative design enables the tool to firmly contact the welding part of the radar bracket. A sliding clamping block is also movably installed on the surface of the positioning block. This design enables the tool to apply appropriate pressure to the radar bracket as needed to ensure the accuracy of the measurement.

[0025] A groove is specially provided on the positioning block, and baffles are provided at both ends of the groove. A spring is installed inside the groove, and a moving protrusion is fixed at the front end of the spring. Baffles are provided on both sides of the moving protrusion, and these baffles are arranged at the rear side of the baffle. The baffle prevents the moving protrusion from falling off, and the moving protrusion is firmly fixed on the positioning block.

[0026] The lifting ring is provided with a fixing groove, which not only enhances the structural stability of the lifting ring, but also facilitates the connection with the lifting equipment.

[0027] In order to further improve the durability and adaptability of the tool, a latex ring is provided between the sliding pressing block and the positioning block to prevent damage caused by friction between the two.

[0028] In addition, a card slot is designed on the inner side of the sliding clamping block, which can better fold the radar bracket when fixing, making the radar bracket more stably fixed and facilitating the detection of the radar direct welding effect.

[0029] Example 2

[0030] Prepare the welded radar bracket to be tested, and insert the positioning block into the radar bracket. The positioning block has two obvious protrusions, and the function of these two protrusions is to accurately fit into the corresponding grooves on the radar bracket. In this way, the positioning block can be firmly fixed on the radar bracket, and the clamping block is slid down to clamp the radar bracket. The function of this clamping block is to prevent the radar bracket from expanding and deforming under the condition of tension. One end of the pull-out force gauge will hook the lifting ring. Before measuring the pull-out force, visually adjust the vertical angle. Make sure that the direction of the pull applied by the pull-out force gauge is consistent with the installation direction of the radar bracket and the positioning block, so as to obtain accurate pull-out force data. During the measurement process, it is necessary to maintain the stability of the pull-out force gauge to avoid the influence of external factors on the measurement results. At the same time, it is also necessary to record the value of the pull-out force for subsequent analysis and comparison.
