[0014] A surface treatment process for automotive parts, characterized by comprising the following steps:

[0016] Step 2: Start the first motor to rotate the first mounting frame 180°, and then place another automotive front axle casting between the other two clamping plates for clamping and fixing.

[0017] Step 3: Start the grinding mechanism, which will then grind the surface of the clamped front axle casting. After grinding, the front axle casting will be manually removed.

[0018] The beneficial effects of this invention are:

[0019] (1) By driving the first motor to rotate the first shaft, the first shaft drives the second shaft to rotate through the first gear and the second gear, the second shaft drives the first mounting frame to flip, and at the same time, the cylinder on the mounting shaft drives the mounting plate, adjusting bolt and clamping plate to clamp and fix the front axle of the automobile front axle casting. Then, the first transmission mechanism drives the mounting shaft to rotate, so that two automobile front axle castings can be clamped and fixed at one time, and castings of different sizes can be clamped and fixed at the same time. At the same time, the clamped castings can be flipped, so that the subsequent grinding mechanism can grind the surfaces of the two castings.

[0020] (2) The transmission plate is moved forward, backward, left and right by the adjustment mechanism. Then, the second transmission mechanism in the first and second transmission boxes drives the second transmission shaft to rotate. The second transmission shaft drives the grinding box to move up and down. The drive mechanism in the grinding box drives the mounting tube and the grinding disc to rotate and grind. This allows two surfaces on two castings to be ground at the same time, which greatly improves the grinding efficiency of the castings. At the same time, the mounting shaft drives the castings to rotate, so as to grind all surfaces on the outer surface of the castings. At the same time, grinding is carried out in the grinding fluid in the box. At the same time, air is supplied to the mounting tube to spray air at the grinding position, thereby improving the fluidity of the grinding fluid at the grinding position, accelerating the heat dissipation at the grinding position, and also accelerating the flow of grinding debris, thus greatly improving the grinding effect of the castings.

[0021] (3) Gas is introduced into the first transmission box and the second transmission box through the air inlet pipe. Then, the first transmission pipe and the second transmission box introduce the gas into the grinding box through the hose, thereby dissipating heat from the second transmission mechanism and the drive mechanism in the first transmission box and the second transmission box, thus greatly improving the heat dissipation effect of the second transmission mechanism and the drive mechanism and ensuring the normal operation of the device.

[0022] (4) By introducing the grinding fluid into the settling tank, then adding flocculant into the settling tank, and then mixing the flocculant with the grinding fluid through the stirring mechanism, the grinding fluid is then subjected to flocculation and sedimentation. The purified grinding fluid is then sucked into the buffer tank through the first liquid pump, suction plate, filter screen and cleaning brush rod. The grinding fluid in the installation box is then introduced into the settling tank. The purified grinding fluid is then introduced into the installation box through the second liquid pump and pipeline, thereby realizing the automatic purification treatment of the grinding fluid and realizing the recycling of the grinding fluid. At the same time, the metal particles in the grinding fluid are effectively purified by the sedimentation method. Attached Figure Description

An adjusting bolt 11 is threaded onto the mounting plate 10, and one end of the adjusting bolt 11 is fixedly connected to a clamping plate 12. A grinding mechanism is provided inside the mounting box 1. By placing the formed automotive front axle casting into the mounting box 1 containing grinding fluid, the cylinder 9 on the mounting shaft 8 inside the first mounting frame 7 drives the mounting plate 10 to move. The mounting plate 10 is then moved by... Adjusting bolt 11 moves clamping plate 12, which then clamps and fixes the casting front axle. Next, first motor 2 drives first rotating shaft 3 to rotate. First rotating shaft 3, through first gear 4 and second gear 5, drives second rotating shaft 6 to rotate. Second rotating shaft 6 rotates first mounting frame 7 180°, allowing another casting front axle to be placed between the other two clamping plates 12 within the first mounting frame 7.

Simultaneously, adjusting bolt 11 can be rotated according to the size of the front axle, moving clamping plate 12 to the appropriate position, thus achieving… The device clamps and fixes front axles of different sizes, and can clamp and fix two casting front axles at the same time. At the same time, the first transmission mechanism drives the mounting shaft 8 to rotate, thereby rotating the clamped castings and grinding each surface of the castings. Then, the grinding mechanism grinds the surfaces of the two castings simultaneously, which greatly improves the grinding efficiency of the casting front axle surfaces. At the same time, the castings are immersed in grinding fluid for grinding, which greatly improves the cooling and lubrication effect during grinding, thereby achieving precise grinding of the casting surfaces and improving the grinding effect of the casting surfaces.

A first transmission box 22 is fixedly connected to one side of the transmission plate 21, and a second transmission box 23 is fixedly connected to one side of the first transmission box 22 via a connecting column. An air pipe is fixedly connected between the first transmission box 22 and the second transmission box 23. A first transmission shaft 24 is rotatably connected inside both the first transmission box 22 and the second transmission box 23. A second transmission mechanism is drivenly connected to the outer surface of the first transmission shaft 24. Both ends of the first transmission shaft 24 are fixedly connected to first threaded rods 25 with opposite threads. A threaded sleeve 26 is threadedly fitted to the outer surface of the first threaded rod 25. The first transmission box 22 has...

The drive mechanism inside the grinding box 28 rotates the mounting tube 29, which in turn rotates the grinding disc 290. The grinding disc 290 polishes the burrs on the surface of the casting, allowing simultaneous polishing of two surfaces on two castings. After polishing, the first transmission mechanism rotates the mounting shaft 8, and then the other two surfaces of each casting are polished simultaneously. This greatly improves the polishing efficiency of the casting front axle on the automobile front axle. Simultaneously, air is supplied to the intake pipe 295 during polishing. The air enters the first transmission box 22 and the second transmission box 23 through the intake pipe 295 and pipes, and then the grinding box 28 is circulated through hoses on the first and second transmission boxes 22 and 23.Subsequently, gas enters the mounting pipe 29 inside the grinding box 28. Under the action of air pressure, it pushes open the sealing baffle 292, at which point the spring 293 stretches. The gas then exits through the mounting pipe 29 and the vent hole 291 on the grinding disc 290. The exiting gas impacts the grinding area, thus promptly flushing away the debris generated during grinding. Simultaneously, it improves the fluidity of the grinding fluid during grinding, thereby enhancing the heat dissipation effect of the grinding fluid on the grinding area. It also promptly removes grinding debris, significantly improving the grinding effect of the grinding disc 290 on the casting. Furthermore, since the second transmission mechanism and drive mechanism also generate a large amount of heat during operation, the gas introduced into the first transmission box 22, the second transmission box 23, and the grinding box 28 also carries away the heat from these components, dissipating heat from the second transmission mechanism and drive mechanism, preventing overheating and motor damage, and ensuring the normal operation of the grinding mechanism.

[0047] A surface treatment process for automotive parts includes the following steps:

[0048] Step 1: Add grinding fluid into the mounting box 1, then place the automotive front axle casting between the two clamping plates 12 in the mounting box 1, and then start the cylinder 9 to clamp and fix the automotive front axle casting.

[0049] Step 2: Start the first motor 2 to drive the first mounting frame 7 to rotate 180°, and then put another automotive front axle casting between the other two clamping plates 12 for clamping and fixing.

[0050] Step 3: Start the grinding mechanism, which will then grind the surface of the clamped front axle casting. After grinding, the front axle casting will be manually removed.

[0051] The working principle of this invention is as follows: A pre-formed automotive front axle casting is placed into a mounting box 1 containing grinding fluid. Then, a cylinder 9 on the mounting shaft 8 within the first mounting frame 7 moves the mounting plate 10. The mounting plate 10 moves the clamping plate 12 via adjusting bolts 11, clamping and fixing the casting front axle. Next, a first motor 2 drives a first rotating shaft 3 to rotate. The first rotating shaft 3, via a first gear 4 and a second gear 5, drives a second rotating shaft 6 to rotate. The second rotating shaft 6 rotates the first mounting frame 7 180°. Another casting front axle is then placed between the other two clamping plates 12 within the first mounting frame 7, and the cylinder 9 clamps and fixes the casting front axle. Simultaneously, according to… The size adjustment bolt 11 of the front axle rotates and moves the clamping plate 12 to a suitable position, thereby clamping and fixing front axles of different sizes. At the same time, it can clamp and fix two casting front axles at one time. Simultaneously, the first transmission mechanism drives the mounting shaft 8 to rotate, thereby rotating the clamped castings and grinding all surfaces of the castings. Then, the grinding mechanism grinds the surfaces of the two castings simultaneously, which greatly improves the grinding efficiency of the casting front axle surface. At the same time, the castings are immersed in grinding fluid for grinding, which greatly improves the cooling and lubrication effect during grinding, thereby achieving precise grinding of the casting surface and improving the grinding effect of the casting surface.

[0052] The first transmission mechanism drives the mounting shaft 8 to rotate, clamping and fixing the two bottom surfaces of the two castings on the first mounting frame 7 in a relative position. The adjustment mechanism drives the transmission plate 21 to move precisely left, right, forward, and backward. Simultaneously, the second transmission mechanism drives the first transmission shaft 24 to rotate in both directions. The first transmission shaft 24 drives two threaded rods 25 with opposite threads to rotate in both directions. The threaded rods 25 drive the threaded sleeve 26 to move precisely up and down. The threaded sleeve 26 drives the grinding box 28 to move precisely up and down. The drive mechanism inside 8 drives the mounting tube 29 to rotate, which in turn drives the grinding disc 290 to rotate. The grinding disc 290 grinds the burrs on the surface of the casting, thus enabling simultaneous grinding of two surfaces on two castings. After grinding, the first transmission mechanism drives the mounting shaft 8 to rotate, and then the other two surfaces of each casting are ground simultaneously. This greatly improves the grinding efficiency of the casting front axle on the automobile front axle. At the same time, air is supplied to the intake pipe 295 during grinding. The air passes through the intake pipe 295 and the pipeline. The gas enters the first transmission box 22 and the second transmission box 23, and then gas is introduced into the grinding box 28 through the hoses on the first transmission box 22 and the second transmission box 23. The gas then enters the mounting pipe 29 inside the grinding box 28, and under the action of air pressure, it pushes open the sealing baffle 292. At this time, the spring 293 is stretched, and then the gas is discharged through the mounting pipe 29 and the vent 291 on the grinding disc 290. The discharged gas impacts the grinding position, thereby washing away the debris generated during grinding in time, and at the same time improving the flow of local grinding fluid during grinding. The grinding fluid improves the heat dissipation effect on the grinding position and removes grinding debris in time, thus greatly improving the grinding effect of the grinding disc 290 on the casting. At the same time, since the second transmission mechanism and the drive mechanism also generate a lot of heat during operation, the gas introduced into the first transmission box 22, the second transmission box 23 and the grinding box 28 will also remove the heat from the first transmission box 22, the second transmission box 23 and the grinding box 28 to dissipate heat from the second transmission mechanism and the drive mechanism, preventing overheating and damage to the motor, thereby ensuring the normal operation of the grinding mechanism.

[0053] After grinding for a period of time, the grinding fluid in the installation tank 1 is discharged into the settling tank 72 through the discharge pipe 71. Then, new grinding fluid is injected into the installation tank 1, and the grinding fluid settles in the settling tank 72. At the same time, flocculant is added to the settling tank 72, and then the mixture is stirred by the stirring mechanism to mix the metal particles in the grinding fluid with the flocculant. After stirring is stopped, the metal particles in the grinding fluid aggregate and settle in the flocculant tank, thereby purifying the grinding fluid. After a period of sedimentation and purification, the purified grinding fluid is discharged through the first liquid pump 75. The grinding fluid is filtered by the suction plate 73 and the filter screen 74, and then the purified grinding fluid is sucked into the buffer tank 76 through the pipeline for buffering. At the same time, the purified sediment is discharged through the discharge pipe. Then, the grinding fluid in the installation tank 1 is discharged into the sedimentation tank 72 through the discharge pipe 71. Then, the second liquid pump 77 pumps the grinding fluid in the buffer tank 76 into the installation tank 1 for reuse, thereby realizing the automatic purification treatment of the grinding fluid and realizing the recycling of the grinding fluid. At the same time, the sedimentation method is used to effectively purify the metal particles in the grinding fluid.
