Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a torque detection device for refrigerator production. Background Art

[0002] For example, the compressor is a crucial component of a refrigerator's refrigeration system, and torque is a crucial indicator of its performance. During the production and manufacturing of refrigerators, torque testing of the compressor is necessary to ensure product quality meets requirements. Several devices have been designed to assist with torque testing.

[0003] For example, the patent with publication number "CN113865769A" discloses a torque detection device for refrigerator compressor production, including a base, a rotating component, a conveying mechanism, a shipping component, a fixing component and a support plate. The two shipping components can fix the boxed compressors to a certain extent during the shipping process of the refrigerator compressor to prevent the refrigerator compressor from falling during the shipping process; the distance between the two shipping components can be flexibly adjusted, so that refrigerator compressors of different sizes and models can be placed between the two shipping components. The patent with application number "CN2022109994074" discloses a torque detection device for refrigerator compressor production, including: a body; a workbench arranged on the top of the body, and the top of the body close to the workbench is slidably connected to a support arm through a guide rail; a movable seat arranged on the inner side of the support arm, and a torque tester is installed on the side wall of the movable seat, and the torque tester is located above the workbench; a lifting assembly, the lifting assembly is arranged on the support arm, and the lifting assembly is used to drive the movable seat to move up and down. The present invention can make the connecting rod drive the workbench to rotate through the cooperation of structures such as a fixed frame, a screw rod, a threaded barrel and a connecting rod, so that the workbench drives the refrigerator compressor to rotate, and then the output end angle of the refrigerator compressor can be adjusted so that it is in the same vertical direction as the detection end of the torque tester, effectively correcting the position deviation and greatly improving the use effect of the equipment.

[0004] All of the above devices are capable of securing the compressor and performing torque detection after delivery. However, their overall structure is relatively complex, with numerous components. Furthermore, since the transmission force application point is located below, while the compressor clamping point is located above, this directly reduces clamping reliability. Furthermore, the significant offset force on the transmission components places a heavy burden on them and is prone to significant wear. Furthermore, the lack of auxiliary components during compressor positioning makes high-precision positioning difficult. Utility Model Content
