Description

TECHNICAL FIELD

[0001] The application relates to a shot blasting device technical field, in particular to an aluminum alloy cylinder head water cavity shot blasting strengthening device. BACKGROUND

[0002] The aluminum alloy cylinder head is a key component of an engine, and the internal water cavity bears the important role of cooling the engine. In the long-term use process, the inner wall of the water cavity is prone to cracks and other defects due to fatigue stress, which affects the service life and safety of the engine. The shot blasting strengthening technology is an effective means to improve the surface strength and fatigue life of metal parts. By spraying high-speed pellets onto the surface of the parts, plastic deformation is generated on the surface, residual compressive stress is formed, and the generation and expansion of cracks are inhibited.

[0003] After the traditional shot blasting equipment is used for shot blasting strengthening treatment of the aluminum alloy cylinder head water cavity, in order to improve the detection accuracy of the subsequent sealing surface flatness, the workpiece needs to be manually transported to a special cleaning equipment for treatment. This operation process not only increases the complexity of the process, but also consumes manpower. Moreover, because the shot blasting equipment and the cleaning equipment are independently arranged, the total floor area is large, the space utilization rate of the production site is low, and the overall process convenience is insufficient.

[0027] The water inlet of the water gun 8 is connected to a water delivery hose 801, and the other end of the water delivery hose 801 is connected to the water outlet of the water delivery equipment.

[0028] Example 2, based on Example 1, such as Figure 1 ,Figure 4 and Figure 8 As shown, the sealing assembly 5 includes a negative pressure cylinder 501, which is installed on the top of the housing 1. The rear end of the negative pressure cylinder 501 is connected to an air supply pipe 502, and the other end of the air supply pipe 502 is connected to a frame-shaped airbag 503. The frame-shaped airbag 503 is fixedly connected to a rectangular opening on the partition plate 106 and is located outside the rotary transposition plate 201. The sealing assembly 5 also includes a support plate 504, which is fixedly connected to the top left side of the housing 1. An electric cylinder B505 is installed on the front end of the support plate 504. The telescopic rod of the electric cylinder B505 passes through the support plate 504, and the rear end of the telescopic rod of the electric cylinder B505 is fixedly connected to... There is a piston 506, and the piston 506 is located inside the negative pressure cylinder 501. Through the setting of the sealing component 5, after the rotation mechanism 3 and the flipping mechanism 4 on both sides complete the exchange, the telescopic rod of the electric cylinder B505 is extended, pushing the piston 506 to move backward in the negative pressure cylinder 501, and forcing the gas inside the negative pressure cylinder 501 into the frame-shaped airbag 503 to expand it. The expanded frame-shaped airbag 503 fits tightly with the rotating shift plate 201, realizing an effective seal between the rotating shift plate 201 and the rectangular opening on the partition 106. This allows the shot peening strengthening device to perform shot peening strengthening and cleaning operations at the same time, improving the shot peening strengthening efficiency of the aluminum alloy cylinder head 9.

[0029] The working principle of this invention is as follows: In use, firstly, a support (such as a wooden block) is placed in the middle of the upper end face of a circular turntable 302 on the left. Then, the aluminum alloy cylinder head 9 to be shot-peened is placed on the upper part of the support, so that the aluminum alloy cylinder head 9 is between the rotating clamping block 406 and the rotating block 408. Then, the clamping screw 404 is rotated. At this time, the clamping screw 404 moves the clamping plate 405 and the rotating clamping block 406 towards the rotating block 408 under the action of the thread. The aluminum alloy cylinder head 9 is clamped and fixed by the rubber pad 4010 on the opposite side of the rotating block 408 and the rotating clamping block 406. Then, the support is removed from between the bottom of the aluminum alloy cylinder head 9 and the upper end face of the circular turntable 302. Then, the left side door is closed, and high-speed shot is sprayed into the water cavity of the aluminum alloy cylinder head 9 by the shot peening gun 7 to strengthen the water cavity. During the shot peening process of the water cavity of the aluminum alloy cylinder head 9, the telescopic rod of the left electric cylinder C602 is controlled by the control box 102 to move left and right, along with the left and right sliding seats 603, the front and rear sliding seats 605 and the shot peening gun 7. The telescopic rod of the left electric cylinder D604 is also controlled by the control box 102 to move back and forth, along with the front and rear sliding seats 605 and the shot peening gun 7. This allows the shot peening gun 7 to be automatically adjusted to the appropriate position according to the position of the water cavity of the aluminum alloy cylinder head 9, eliminating the need for manual operation and greatly improving the convenience of the shot peening process.

[0030] Furthermore, during the shot peening process, the rotary motor 303 can be controlled by the control box 102 to rotate the circular turntable 302, the flipping mechanism 4, and the aluminum alloy cylinder head 9 horizontally, thereby adjusting the horizontal angle of the aluminum alloy cylinder head 9. Then, the control box 102 controls the motor 409 to rotate forward and backward, driving the worm, worm wheel, transverse rotating shaft 407, and rotating block 408 to rotate forward and backward, thereby adjusting the vertical tilt angle of the aluminum alloy cylinder head 9, thus improving the shot peening effect of this shot peening device.

[0031] After the aluminum alloy cylinder head 9 water cavity has undergone shot peening strengthening treatment, the telescopic rod of electric cylinder B505 is retracted by control box 102, causing piston 506 to move forward linearly inside negative pressure cylinder 501. This draws gas from inside frame-shaped airbag 503 into negative pressure cylinder 501 via air supply pipe 502. At this time, frame-shaped airbag 503 is in a deflated state and is not in contact with rotary shift plate 201. Then, the telescopic rod of electric cylinder A206 is extended by control box 102, causing rack 207 to move to the left. This drives gear 204, vertical shaft 202, and rotary shift plate 201 to rotate clockwise. When the telescopic rod of electric cylinder A206 extends to its limit position, rotary shift plate 201 rotates 180 degrees clockwise. At this time, rotary shift plate 201 carries two L-shaped support frames 20 3. The two rotating mechanisms 3, the two flipping mechanisms 4, and the aluminum alloy cylinder head 9 rotate 180 degrees clockwise, bringing the shot-peened aluminum alloy cylinder head 9 into the right-side chamber of the housing 1. Then, the telescopic rod of the electric cylinder B505 is extended by the control box 102, causing the piston 506 to move backward linearly inside the negative pressure cylinder 501. This pushes the gas inside the negative pressure cylinder 501 into the frame-shaped airbag 503 through the air supply pipe 502. At this time, the frame-shaped airbag 503 is in an inflated state and is in close contact with the rotating transposition plate 201, so that the rotating transposition plate 201 and the rectangular opening of the partition 106 are effectively sealed. This allows the shot-peening device to perform shot-peening and cleaning work simultaneously, further improving the efficiency of shot-peening the aluminum alloy cylinder head 9.

[0032] Next, the cleaning solution is delivered to the inside of the water spray gun 8 through the water supply hose 801 via an external water supply device. Then, the cleaning solution is sprayed onto the water cavity and sealing surface of the aluminum alloy cylinder head 9 through the water spray gun 8 to wash away the shot and other particles in the water cavity and sealing surface of the aluminum alloy cylinder head 9. In the process of transferring the aluminum alloy cylinder head 9, since there is no need for manual transfer, it not only greatly reduces the complexity of the process and saves manpower for handling, but also effectively reduces the overall footprint because this shot peening strengthening device adopts an integrated design of shot peening and cleaning, thereby improving the space utilization rate of the production site and enhancing the convenience of the overall process.
