Description

A shot blasting machine for the production of motor castings

Technical field

The invention relates to the technical field of motor housing processing equipment, specifically a shot blasting machine for the production of motor castings.

Background technique

Casting is a manufacturing process in which smelted metal liquid is poured into a mold and cooled and solidified to obtain parts with the required shape and performance. Motor casings are mostly produced by casting, and there are often burrs on the surface after production. Therefore, polishing is often used. The shot blasting machine strengthens the surface of the casting, and simultaneously shakes off the sand, removes the core and cleans the casting. Since the motor casing is similar to a cylindrical shape, most existing shot blasting machines spray continuously over a wide range and cannot fix the fixed point (point position) on the surface of the workpiece. ) for cleaning, that is, for equipment that does not require comprehensive shot blasting, point-based treatment is performed. However, because the parts that need to be treated are not the same, the injection direction needs to be adjusted and the steel shots after injection are recycled and continued to be sprayed. If If the existing equipment is used for comprehensive blasting treatment, the parts that do not need to be treated will be affected by the steel shot blasting. Therefore, a shot blasting machine is designed for the production of motor castings.

Embodiment: According to Figures 1-11 of the description, it can be seen that a shot blasting method of a shot blasting machine for motor casting production includes the following steps: Step (1): First, the motor shell can be passed through the second motor 175 in the firmware unit 17 Drive, drive the first screw rod 174 to rotate, drive the two clamping arms 176 to move relative, use the clamping hand 177 to clamp the motor housing for fixation, and then control the first cylinder 15 in the feeding structure 1 to make the feeding frame 14 move in the guide Move up the material box 11 and move the motor shell into the shot blasting box 20 and between the two sets of sandblasting components; step (2), you can also use the guide roller 13 between the guide frames 12 to prevent other workpieces to be used in the shot blasting box 20; step (3), by controlling the feeding pump 35 in the return structure 3 to drive, the particles in the collecting box 32 are extracted and transported to the material distribution box 34 on the bracket 33. The material distribution box 34 diverts the flow into the four spray barrels 273; step (4), simultaneously controls the shot blasting assembly 22 in the shot blasting structure 2 with the help of the controller 21, so that the fourth motor 274 drives the second gear 275 in the force application box 271 Rotate, force the force-applying gear rod 277 to move toward the spring 276, and squeeze the spring 276 in the force-applying cylinder 272 to accumulate force. At this time, the nozzle moves to the rear side of the feed port, and the particles can enter the spray cylinder 273. , and when the second half-toothed gear 275 cannot mesh with the force-applying gear rod 277, the force-applying gear rod 277 receives the reverse force of the spring 276, driving the ejection port 278 to pop up quickly, pushing the particles to be ejected, and achieving injection and shot blasting.

Enter the projectile; step (6), drive the first motor 172 on the rotating frame 171 through the four spray tubes 273 facing the motor housing to drive the turntable 173 to rotate, thereby driving the motor housing to rotate, thereby achieving comprehensive spray treatment ; The first hydraulic cylinder 18 can also be driven to drive the rotating frame 171 to flip and move on the folding seat 16, and the motor housing can be tilted to be parallel to the two relatively staggered and symmetrical injection tubes 273, so that the motor housing can be adjusted The inner wall of the inner wall is sprayed; step (7), fixed-point spraying can also be carried out according to the use requirements to prevent the shot blasting from affecting the appearance of other parts; then adjust the position of the motor housing workpiece according to the needs, and drive the throwing rack in the shot blasting assembly 22 The third motor 223 on the throwing rack 221 is driven to drive the second screw rod 222 to rotate, so that the moving rack 224 is forced to move relative or towards each other on the throwing rack 221, and is driven by the engagement between the moving rack 224 and the first gear 226. The pin arm 225 is driven to rotate, so that the injection tube 273 and the force-bearing tube in the shot blasting unit 227 are turned over and tilted, so that they are opposite to the injection part, and the shot blasting unit 227 can be driven independently to achieve fixed-point shot blasting;

In the above-mentioned fixed-point spraying, since the workpiece may not necessarily have defects at the same position after production, the inclination angle of the spray tube 273 relative to the workpiece is also different in the point-position spraying process, and according to actual needs, the inclination angle of the workpiece can also be controlled. Flip, tilt and rotate to cooperate, corresponding to the ejection end of the spray tube 273, and can independently drive a shot blasting unit 227 for spray processing; and the above operation drive does not need to be calibrated by the naked eye of the human body, and can be controlled using the existing technology You can adjust the drive using the device’s programming system;

In addition, this equipment can achieve comprehensive spray treatment of the workpiece, and can also perform positioning spray treatment on defects at different locations (the fixed point mentioned in this case is not the same part of the workpiece, but a location and point for the treatment part. bit processing).

Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art will understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principles and spirit of the invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
