Problems solved by technology

However, whether it is liquid sandblasting or high-pressure water jet sandblasting, the principle is to use the high-speed impact of abrasives to remove surface attachments. If the splines at both ends of the constant velocity universal joint drive shaft are not protected, they will be damaged by abrasives. Imprints will be produced due to impact, which will affect the surface finish and surface accuracy, thereby affecting the performance of the car and even causing safety hazards
At present, there is no equipment for blasting surface cleaning that can meet the requirements

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 and figure 2 As shown, the sandblasting machine for the transmission shaft of the present invention includes a frame 1 and a sandblasting mechanism 6 installed on the frame 1. The sandblasting mechanism 6 includes a reciprocating mechanism positioned at the top of the frame 1 and a reciprocating The spray head connected by the kinematic mechanism, the reciprocating stroke, reciprocating speed, spraying distance and spraying angle of the sandblasting mechanism 6 are adjustable. There are two sets of positioning assemblies 8 for placing the transmission shaft 4 below the sandblasting mechanism 6. The connecting lines of the two sets of positioning assemblies 8 are parallel to the horizontal plane. The distance between the two sets of positioning assemblies 8 is equal to the distance between the splines at both ...

Abstract

The invention discloses a sand spraying machine for a transmission shaft. The sand spraying machine comprises a machine frame and a sand spraying mechanism which is arranged on the machine frame; two groups of poisoning assemblies for placing the transmission shaft are placed below the sand spraying mechanism; the distance between two groups of poisoning assemblies is equal to the distance between splines at two ends of the transmission shaft; each group of the positioning assemblies comprises two rotation pieces which are opposite to each other; and a distance is reserved between two rotation pieces and is smaller than the diameter, at the spline, of the transmission shaft. The sand spraying machine has a simple structure, can spray sand uniformly, and avoid the phenomenon that the splines at two ends of the transmission shaft can be prevented from being impacted by an adhesive.

Description

technical field [0001] The invention mainly relates to the field of sandblasting equipment, in particular to a sandblasting machine used for transmission shafts. Background technique [0002] The constant velocity universal joint drive shaft is one of the main components in the chassis transmission system, and it is often used in cars with front-engine front-wheel drive, front-engine rear-wheel drive or four-wheel drive. Damage, wear, corrosion, deformation and loss of dynamic balance of drive shaft parts will cause abnormal noise and vibration during driving, and in severe cases, it will cause damage to related components and cause safety accidents. [0003] Since the constant velocity universal joint transmission shaft of the automobile is exposed in the atmosphere, it is often corroded and rusted due to atmospheric moisture or pollutants. , Before the anti-corrosion treatment of the surface coating, it is necessary to remove the oil, rust and other attachments on the sur...
