Description

Crankshaft shot blasting machine

technical field

The utility model relates to a surface treatment device, in particular to a crankshaft shot blasting cleaning machine.

Background technique

In the foundry industry, with the rapid development of the automobile industry, the sand removal and cleaning process requirements for castings such as the crankshaft of the automobile engine part that have an important impact on product performance have increased accordingly. The current cleaning of the crankshaft generally uses a hook-type shot blasting machine to perform shot blasting on the workpiece. The workpiece on the spreader is surface cleaned. However, the shot blasting machine with this structure has the following defects: (1) waste of energy and low efficiency: the crankshaft rotates around the center of the spreader, there is a fixed part of the area that accepts the high-speed direct shot of the steel shot, and a part of the area can only accept the low-speed shot of the steel shot Scattering causes the projectile energy received by the surface of the workpiece to be uneven, so some places on the outer surface of the workpiece are hit excessively, and some places are not cleaned thoroughly. In order to clean the workpiece, the working time of the shot blasting machine can only be extended, resulting in a waste of energy and time. (2) The cleaned workpiece has a dark side, and the quality is not ideal: when the crankshaft is placed on the spreader, the contact surface with the spreader is hardly thrown by the steel shot, so the cleaned workpiece has a dark side, and the cleaning quality is not high.

The technical scheme of the utility model is: a crankshaft shot blasting cleaning machine, including a shot blasting device arranged above the shot blasting chamber, characterized in that: the shot blasting chamber is provided with two sets of symmetrically arranged workpiece rotation devices 1 and a workpiece Autorotation device II; the workpiece autorotation device I and workpiece autorotation device II are fixedly connected by the rotating body assembly arranged on both sides of the shot blasting chamber; the rotating body assembly includes the left end plate of the rotating body, the right end plate of the rotating body and the rotating body The motor, the left end plate of the rotating body and the right end plate of the rotating body are connected to the base through bearings; The workpiece rotation device II is connected.

The workpiece rotation device includes a left end plate of the workpiece rotation device and a right end plate of the workpiece rotation device. Axes I, II, III, and IV are installed between the two end plates, and a motor is installed at the right end of the shaft I. The motor passes through Sprocket Ⅴ and sprocket Ⅵ drive each shaft to rotate.

There is a sprocket mechanism between the left end plate of the rotating body and the left end plate of the workpiece rotating device, and the sprocket mechanism is composed of sprocket I, sprocket III, sprocket II and multiple chains.

A crankshaft support plate is installed in the middle of the shafts II, III and IV.

Four blasting devices are installed on the top of the blasting chamber.

The side of the shot blasting chamber is provided with a feeding port, and an loading and unloading arm of an industrial robot is provided at the feeding port.

The beneficial effect of the utility model can be obtained through the above scheme: since the workpiece is transported to the loading position of the industrial robot through the feeding mechanism, the workpiece is grabbed by the industrial robot and put into the unloading station, and the rotation of the shot blasting chamber The device rotates the workpiece to the blasting station for shot blasting. During the rotation, a sprocket mechanism is designed to ensure that the workpiece is always in a horizontal state. During shot blasting, the workpiece rotation device makes the workpiece (crankshaft) rotate around its own axis, so that the workpiece is always within the optimal throwing distance. At the shot blasting station, while the shot blasting is being cleaned, the industrial robot takes out the previous workpiece from the unloading station, and puts the next workpiece into the unloading station, so as to realize the synchronization of shot blasting cleaning and loading and unloading . The workpiece rotation device and the double-station rotation device ensure that the projectile energy received by the workpiece surface is uniform, effectively avoiding the unsatisfactory quality of the dark side of the workpiece, and at the same time greatly improving the working efficiency of the equipment and avoiding waste of energy and time.

It can be seen that the utility model has substantive features and progress compared with the prior art, and the beneficial effects of its implementation are also obvious.

Detailed ways:

In order to better understand the utility model, the implementation of the utility model will be explained in detail below in conjunction with the accompanying drawings.

Specific embodiments: as shown in Figures 1 and 2, a crankshaft shot blasting machine includes a shot blasting chamber 6, and four blasting devices 7 are installed on the top of the shot blasting chamber 6. The shot blasting chamber 6 is provided with two sets of symmetrically arranged workpiece rotation devices I 13 and workpiece rotation devices II 14; The body assembly 9 is fixedly connected; the rotating body assembly 9 includes the rotating body left end plate 5, the rotating body right end plate 8 and the rotating body motor 10, and the rotating body left end plate 5 and the rotating body right end plate 8 are connected to the base 1 through bearings Connected; the left end plate 5 of the rotating body and the right end plate 8 of the rotating body correspond to two circular holes respectively, and are connected with the workpiece rotation device I 13 and the workpiece rotation device II 14 through bearings and rollers.
