Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a punching support device for a copper sleeve of a medical X-ray tube rotor. Background Art

[0002] The copper sleeve of the rotor of the medical X-ray tube acts as a bridge connecting the bearing and the target plate, and also transfers the heat of the target plate and radiates it. The copper sleeve of the rotor of the medical X-ray tube needs to be punched during production, because the rotor inevitably has deviations during manufacturing and welding, causing the center of gravity to be not on the axis, and it will vibrate if it rotates at high speed. Punching is to remove some of the excess weight and return the overall center of gravity to the axis, so that the high-speed rotation is relatively stable.

[0003] Now when drilling holes on the rotor, the drill presses down to drill the holes, and the inner circular surface has no support, so the rotor is easily flattened and deformed, resulting in eccentric and unbalanced rotation of the rotor. Utility Model Content

[0004] In view of this, an embodiment of the utility model provides a medical X-ray tube heat dissipation device to reduce rotor deformation and ensure the cylindricity of the rotor.

[0006] Furthermore, the plunger includes column one and column two, column one is located at the front end of column two, the outer diameter of column one is smaller than the outer diameter of column two, the outer diameter of column one is smaller than or equal to the inner diameter of the rotor, and mounting hole one and mounting hole two are provided at the bottom of the plunger, mounting hole one is located at the front end, mounting hole two is located at the rear end, and the diameter of mounting hole one is larger than the diameter of mounting hole two.

[0007] Furthermore, two avoidance grooves parallel to the axis of the plunger are provided at the second mounting hole.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] As shown in the figure, the embodiment of the utility model discloses a punching support device for a copper sleeve of a rotor of a medical X-ray tube, comprising a base 1, a target plate placement groove 11 and a rotor placement groove 12 are provided on the base 1, a portion of the target plate 4 is placed at the target plate placement groove, a portion of the rotor 2 is placed at the rotor placement groove, the front end of the rotor 2 is connected to the target plate 4, the front end of the bearing 3 is connected to the rotor 2, the rear end of the bearing 3 is located in the plunger 6, the front end of the plunger 6 is located inside the rear end of the rotor 2, a pressing block 7 is provided at the upper end of the plunger 6, and both ends of the pressing block 7 are connected to the top of the base 1. The utility model arranges the plunger 6, and the front end of the plunger 6 is pressed against the inner surface of the rotor 2, so as to rigidly support the rotor, thereby reducing the deformation of the rotor and ensuring the cylindricity of the rotor.
