Description

Multidirectional anticollision compressor Technical Field The invention relates to the technical field of compressors, in particular to a multidirectional anti-collision compressor. Background The inside spring shock-absorbing structure that adopts of totally closed small-size piston compressor, when the compressor and the utensil transportation that is equipped with the compressor, the pump body part can shake certainly, because shake the pump body and the casing part of compressor and produce the collision, ideal state is guaranteed after the transportation: 1. the relative position of the mechanical part of the pump body and the motor cannot be changed after collision, otherwise, the starting capability and efficiency of the compressor can be reduced when the motor air gap becomes uneven; 2. the form and position tolerance of the moving part cannot be changed, the impact force exceeds the strength of the structure, the structure is permanently deformed to damage the form and position tolerance, the performance is reduced, and the abrasion and even the jamming risks are accelerated; 3. foreign matters (such as scrap iron, plastic scraps and the like) cannot be generated, otherwise, the compressor cannot be operated or the service life is shortened. Particularly, the requirements on the field of refrigerators can be met when the device is used for lying and transporting, damping springs are not arranged in the lying direction generally, the free travel is larger (the distance between a pump body and a shell is generally 4-6mm, the impact distance in the direction in which the damping springs are arranged in the forward direction can be generally designed to be 2-3 mm), and the impact force of the lying and transporting is larger; 4. the compressor for mobile use scenarios, such as on-board refrigeration appliances, should also have low impact noise. The prior compressor anticollision part is designed on a frame, the frame is an iron casting, a crankshaft hole and a cylinder hole are designed on the frame, a plurality of anticollision point blanks are designed on the horizontal direction and the vertical upward direction of the compressor to be integrally cast, and the points are used as anticollision points during transportation. To solve problem 1, a high strength high tightening torque screw connection (usually at least 10.9 grade screws, tightening torque above 10N/M, fine threads) is used between the frame and the motor stator to bear the impact force, and the thread quality is strictly controlled in the manufacturing process. Under the adverse factors of poor transportation road conditions, long distance, thread defects and the like, the screw can still be invalid; in order to solve the problem 2, the frame design needs to consider enough rigidity and strength, so that the frame cannot be damaged when bearing impact energy and deformation cannot damage the form and position tolerance of the moving part, and the frame design is thick and heavy and pays cost; In order to solve problem 3, the distance between the anti-collision point and the shell is reduced, and the impact energy is reduced, but at least more than 3mm is required to accommodate various accumulated tolerances in the manufacturing process and the impact of the pump body during the running and stopping of the compressor to ensure that the shell is not collided. However, as the anti-collision points are formed by casting and have rough surfaces, particularly when lying and transporting, the impact energy is concentrated at the anti-collision points, the impact force born by the anti-collision points is larger than that when the anti-collision points are placed at the using positions, and the quality risk of generating foreign matters is large; To solve problem 4, a non-metallic material anti-collision structure is added to reduce the collision noise, so that the collision noise is ensured to be reduced in all directions, a plurality of non-metallic collision points are required to be designed, and the cost is increased. Based on the above circumstances, the present invention provides a multi-directional anti-collision compressor, which can effectively solve one or more of the above problems.
