Description

Technical Field

[0001] The invention relates to the technical field of automobile flywheel housing casting, in particular to a special hanger for automobile flywheel housing casting and a use method thereof. Background Art

[0002] The automobile flywheel is a disc-shaped part with a large moment of inertia, which acts like an energy storage device. For a four-stroke engine, work is performed once every four piston strokes, that is, only the power stroke performs work, while the exhaust, intake and compression strokes all consume work. Shot blasting is an important part of the casting process of automobile flywheel housings. It is achieved by shot blasting machines. The high-speed projectiles thrown by the shot blasting machine are used to clean or strengthen the surface of the casting. The shot blasting machine can simultaneously perform sand dropping, core removal and cleaning operations on the castings. When the shot blasting machine is operating, the flywheel housing needs to be placed on a rack, and then the rack and the workpiece are synchronously fed into the shot blasting machine.

[0003] However, after the existing automobile flywheel housing casting bracket is processed once, it needs to be taken out again, and the workpiece angle needs to be adjusted before it is put into the equipment for processing again. This reciprocating process can ensure that the shot blasting is thorough, and the efficiency is low. Therefore, it does not meet the existing needs. In this regard, we propose a special bracket for automobile flywheel housing casting and a method for using the same. Summary of the invention

[0014] Preferably, the method for using the special bracket for casting a flywheel housing of an automobile comprises the following steps:

[0015] Step 1: During operation, hang the flywheel housing of the car on the hanging rods around the pillars, make the flywheel housing close to the limit plate at one end of the hanging rod, and use the hand wheel to rotate the screw on the clamping seat so that the rubber head at one end of the screw presses the flywheel housing to achieve the effect of squeezing and fixing;

[0016] Step 2: After the flywheel housing is mounted, adjust the number of counterweights on the base according to the current overall weight of the rack to lower the center of gravity of the rack;

[0017] Step 3: Connect the hanging ring on the upper end of the hanger to the hanging mechanism, and rely on the hanging mechanism to lift the hanger together with the workpiece into the shot blasting machine;

[0018] Step 4: Start the shot blasting machine and use the high-speed projectiles thrown by the shot blasting machine to clean and strengthen the surface of the workpiece. During the treatment, the stepper motor at the lower end of the rack is driven to drive the column and the surrounding hanging rods to rotate, and the processing angle of the workpiece is continuously adjusted to make the shot blasting more comprehensive and thorough;

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention sets a driving bin at the lower end of the rack, in which a stepper motor is installed, and the output end of the stepper motor is connected to the column of the rack by transmission. After the rack is hoisted to the shot blasting machine, the stepper motor can drive the column and the surrounding hanging rods to rotate, and continuously adjust the position of the workpiece to facilitate multi-angle contact between the workpiece and the high-speed projectile thrown by the shot blasting machine, so as to achieve a comprehensive shot blasting effect. Compared with the prior art, there is no need to take out the rack many times, adjust the angle and then put it back into the equipment, so the manpower consumption is reduced and the efficiency is high.

[0022] 2. By setting a limit plate and a clamping seat at one end of the hanging rod, when in use, the flywheel housing of the car is hung on the hanging rods around the column, so that the flywheel housing is close to the limit plate at one end of the hanging rod, and the screw on the clamping seat is rotated by the hand wheel to make the rubber head at one end of the screw press the flywheel housing to achieve the effect of squeezing and fixing, thereby reducing the high-speed projectile impacting the workpiece during shot blasting, causing the workpiece to fall off from the bracket.

[0023] 3. By setting a water pipe at the upper end of the hanger, after shot blasting, the external water pipe can be connected to the water pipe connecting valve on the outside of the water pipe, so that clean water enters the cross spray pipe along the water pipe, and the water is sprayed onto the workpiece through the nozzle to achieve a quick cleaning effect. Because there are three groups of hanging rods from bottom to top, and the length gradually decreases, the upper layer will not cover the lower layer during cleaning.

[0024] 4. By installing threaded rods on both sides of the upper surface of the base, when the bracket is in use, the weight of the base can be adjusted by installing counterweights on the threaded rods to lower the center of gravity of the bracket. Compared with conventional brackets, the processing stability is significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS
