DETAILED DESCRIPTION

[0023] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0024] like Figure 1-6As shown, the present invention provides a technical solution: a shell spray repair device for engine remanufacturing, comprising a mounting base 1, a rotating groove 101 is provided on the top of the mounting base 1, an annular slide groove 102 is provided on the bottom of the rotating groove 101, a rotating motor 103 is embedded and fixedly installed on the bottom of the mounting base 1, a rotating gear 104 is fixedly installed on the output end of the rotating motor 103, a rotating gear 2 105 is meshed on the surface of the rotating gear 104, and the rotating gear 2 105 is rotatably connected with the mounting base 1, and the rotating motor 103 is provided to control the rotating motor 103 to rotate, so as to drive the rotating gear 104 at the output end of the rotating motor 103 to rotate, thereby controlling the rotating gear 2 105 meshed with the rotating gear 104 to rotate synchronously, so that the placement turntable 106 on the top of the rotating gear 2 105 rotates inside the rotating groove 101, and the engine shell placed on the top of the placement turntable 106 is adjusted to face the strip nozzle 5.

[0025] The top of the rotating gear 105 extends to the inside of the rotating groove 101, and a placing turntable 106 is fixedly installed therein. A plurality of groups of rotating balls 107 are inlaid and rollingly installed at the bottom of the placing turntable 106. The rotating balls 107 correspond to the positions of the annular slide groove 102, and the rotating balls 107 are slidably connected inside the annular slide groove 102. Because the annular slide groove 102 and the rotating balls 107 are provided, when the placing turntable 106 rotates inside the rotating groove 101 along with the rotating gear 105, the rotating balls 107 at the bottom of the placing turntable 106 are driven to roll inside the annular slide groove 102, thereby reducing the friction between the placing turntable 106 and the bottom of the rotating groove 101 when the placing turntable 106 rotates inside the rotating groove 101.

[0026] Electric push rods 2 are fixedly installed at the four corners of the top of the mounting base 1, and a clamping top plate 3 is fixedly installed on the top of the four groups of electric push rods 2, and the clamping top plate 3 corresponds to the position of the mounting base 1. A connecting ring 301 is provided at the central position of the top of the clamping top plate 3, and four groups of clamping columns 302 are fixedly installed at the bottom of the connecting ring 301 at equal angles, and the bottom ends of the four groups of clamping columns 302 pass through the clamping top plate 3 and are fixedly installed with a clamping plate 303. A clamping spring 305 is provided on the surface of the clamping column 302 located between the clamping top plate 3 and the clamping plate 303, and a clamping spring 305 is provided on the surface of the clamping column 302 between the clamping top plate 3 and the clamping plate 303. By providing an electric push rod 2 and a clamping spring 305, after the engine casing is placed on the top of the placing turntable 106 corresponding to the position of the clamping turntable 306, the electric push rod 2 is controlled to contract and drive the clamping top plate 3 to move down and press against the top of the engine casing until the clamping turntable 306 presses against the top of the engine casing, so that the clamping spring 305 is squeezed and deformed, and the clamping turntable 306 is pressed against the top of the engine casing under the rebound action of the clamping spring 305, thereby pressing the engine casing between the placing turntable 106 and the clamping turntable 306.

[0027] A plurality of groups of rotating balls 304 are inlaid and installed at equal angles at the bottom of the pressing plate 303. A pressing turntable 306 is installed at the bottom of the pressing plate 303. A second annular groove 307 is provided on the top of the pressing turntable 306. The second annular groove 307 corresponds to the position of the second rotating ball 304. Since the second rotating ball 304 and the second annular groove 307 are provided, after the pressing turntable 306 is pressed on the top of the engine casing, the pressing turntable 306 rotates synchronously with the engine casing, driving the second annular groove 307 to rotate at the bottom of the second rotating ball 304, so that the second rotating ball 304 rolls at the bottom of the pressing plate 303, thereby reducing the friction when the pressing plate 303 and the pressing turntable 306 rotate relative to each other.

[0028] A retaining ring 308 is fixedly installed on the top of the clamping turntable 306, and the retaining ring 308 is slidably connected to the surface of the clamping plate 303. Because of the retaining ring 308, when the clamping turntable 306 is pressed on the top of the engine casing, the top of the retaining ring 308 is in close contact with the clamping top plate 3. When the strip nozzle 5 sprays the surface of the engine casing, excess paint sprayed onto the clamping turntable 306 is blocked by the retaining ring 308, preventing excess paint from being sprayed on the surface of the clamping column 302 and the clamping spring 305.

[0029] The mounting side frames 4 are symmetrically fixedly installed on both sides of the top of the mounting base 1, a limited sliding bar 401 is fixedly installed on one side of the inner side frame 4, a limited sliding bar 402 is fixedly installed on the top of the mounting side frame 4, a moving seat 403 is slidably installed on the surface of the limited sliding bar 401, and a moving seat 404 is slidably installed on the surface of the limited sliding bar 402, and a rotating connecting frame 405 is provided between the moving seat 403 and the moving seat 404. 02, under the connecting action of the rotating connecting frame 405, the moving seat 1 403 and the moving seat 2 404 are driven to slide on the surfaces of the corresponding limiting slide bar 1 401 and the limiting slide bar 2 402, and the movement of the moving seat 1 403 and the moving seat 2 404 is limited to ensure that the rotating connecting frame 405 will not tilt or deflect when pulling the moving seat 1 403 and the moving seat 2 404 to move, and at the same time, it is convenient to adjust the height of the strip nozzle 5 between the two groups of moving seats 1 403 between the two groups of mounting side frames 4.

[0030] Support plates 406 are symmetrically fixedly installed on both sides of the top of the side frame 4, and an adjusting stud 407 is rotatably installed between the two groups of support plates 406. The top of the movable seat 404 is threadedly connected to the surface of the adjusting stud 407, and one end of the adjusting stud 407 passes through the support plate 406 and is fixedly installed with a bevel gear 408. Due to the provision of the adjusting stud 407, the bevel gear 408 transmits the rotation of the double-output shaft motor 702 to the adjusting stud 407. When the adjusting stud 407 is controlled to rotate between the two groups of support plates 406, the movable seat 404 on the surface of the adjusting stud 407 is driven to slide on the surface of the limiting slide rod 402.

[0031] A strip-shaped spray head 5 is provided between the two sets of mounting side frames 4, and a baffle plate 6 is fixedly installed on one side of the top of the mounting base 1 between the two sets of mounting side frames 4. Due to the baffle plate 6, the strip-shaped spray head 5 sprays excess paint toward the engine housing toward the baffle plate 6 to prevent excess paint from flying around;

[0032] The top of the baffle plate 6 is fixedly installed with a mounting top plate 7 between the two groups of mounting side frames 4. Support plates 2 701 are symmetrically fixedly installed on both sides of the top of the mounting top plate 7, and a double-output shaft motor 702 is fixedly installed at the central position of the top of the mounting top plate 7. Rotating shafts 703 are symmetrically arranged on both sides of the double-output shaft motor 702. One end of the rotating shaft 703 passes through the supporting plate 2 701 and is fixedly installed with a bevel gear 2 704, and the bevel gear 2 704 is meshed with the bevel gear 1 408. By providing the double-output shaft motor 702 and the rotating shaft 703, the double-output shaft motor 702 is controlled to rotate, driving the two groups of rotating shafts 703 to rotate synchronously, so that the bevel gear 2 704 at one end of the two groups of rotating shafts 703 away from the double-output shaft motor 702 rotates synchronously, and the rotation is transmitted to the adjusting stud 407 through the meshing with the bevel gear 1 408, thereby controlling the two groups of adjusting studs 407 to rotate synchronously, driving the two groups of moving seats 2 404 to move synchronously on the corresponding surface of the limit slide bar 2 402.

[0033] The working principle of the present invention is:

[0034] The four groups of electric push rods 2 are controlled to extend at the same time, driving the pressing top plate 3 to move up and away from the mounting base 1 between the two groups of mounting side frames 4, so that the distance between the placement turntable 106 and the pressing turntable 306 is increased, and the engine casing is moved to the central position of the top of the placement turntable 106, and the pressing turntable 306 is suspended on the top of the engine casing, and the four groups of electric push rods 2 are controlled to shrink at the same time, driving the pressing top plate 3 to move down between the two groups of mounting side frames 4, until the pressing turntable 306 moves down and is close to the top of the engine casing, and the electric push rods 2 are controlled to continue to shrink, so that the pressing top plate 3 continues to compress the distance between the small pressing top plate 3 and the pressing plate 303, and the pressing spring 305 is squeezed and deformed, and the pressing turntable 306 is pressed against the top of the engine casing under the rebound action of the pressing spring 305, so that the engine casing is pressed and fixed between the placement turntable 106 and the pressing turntable 306;

[0035] The rotating motor 103 is started to control the rotating gear 104 to rotate, thereby controlling the rotating gear 2 105 meshing with the rotating gear 104 to rotate synchronously, so that the placement turntable 106 rotates inside the rotating groove 101, driving the engine housing on the top of the placement turntable 106 to rotate synchronously with the placement turntable 106, and at the same time, the pressing turntable 306 rotates synchronously with the engine housing on the top of the pressing plate 303, and at the same time, the strip nozzle 5 is started to spray the surface of the engine housing, and the double-output shaft motor 702 is controlled to drive the two sets of rotating shafts 703 to rotate synchronously, and the rotation of the double-output shaft motor 702 is transmitted through the bevel gear 1 408. The meshing of the bevel gear 704 is transmitted to the adjusting stud 407, which controls the two groups of adjusting studs 407 to rotate synchronously, so that the moving seat 404 slides on the surface of the corresponding adjusting stud 407 and the limiting slide bar 402, and the moving seat 403 is pulled up and down on the surface of the corresponding limiting slide bar 401 under the pull of the rotating connecting frame 405, driving the strip nozzle 5 between the two groups of moving seats 403 to move up and down between the two groups of mounting side frames 4, and spraying the surface of the engine casing fixed between the pressing turntable 306 and the placing turntable 106 up and down, so as to evenly spray different positions on the surface of the engine casing.
