[0002] Automobile engines provide power for automobiles by converting other forms of energy into mechanical energy. Depending on the power source, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors and hybrid power. Common gasoline engines and diesel engines are both reciprocating piston internal combustion engines, which convert the chemical energy of fuel into mechanical energy of piston movement and output power to the outside.

[0003] Since the engine consists of many parts, the engine cylinder block needs to be fixed when assembling or maintaining the engine to prevent the cylinder block from sliding during assembly and maintenance. However, some current maintenance platforms are fixed, which makes it difficult to adjust the height according to the operator's needs, resulting in reduced practicality. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a fixing and clamping device for automobile engine parts, which solves the problem that some current maintenance platforms are fixed and cannot be adjusted in height according to the operator's needs, resulting in reduced practicality.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing and clamping device for automobile engine parts, comprising a base, a mounting plate connected to the base, a support column connected to the top of the base, a hollow column connected to the center of the top of the base, a lifting column slidably connected in the hollow column, a fixed platform connected to the lifting column, a first slide groove provided on the fixed platform, a second slide groove provided on the fixed platform, a first threaded rod rotatably connected in the second slide groove, a rotating wheel connected to one end of the first threaded rod, a moving block installed on the first threaded rod, and a threaded sleeve installed on the moving block;

[0008] As a further solution of the utility model: a return spring is connected below the pressure plate, one end of the return spring is connected to the slider, the slider and the moving block are both I-shaped and fit with the first slide groove and the second slide groove respectively.

[0009] As a further solution of the utility model: a sliding hole is opened on the support column, a smooth rod is connected below the fixed platform, and the smooth rod is slidably connected to the support column through the sliding hole.

[0010] As a further solution of the utility model: a limiting groove is provided on the inner wall of the hollow column, and a limiting strip is connected to the outer wall of the lifting column.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a fixing and clamping device for automobile engine parts, comprising a base 1, a mounting plate 2 is connected to the base 1, a supporting column 3 is connected above the base 1, a hollow column 4 is connected at the center above the base 1, a lifting column 5 is slidably connected in the hollow column 4, a threaded hole 30 is provided in the lifting column 5, a second threaded rod 28 is threadedly matched with the threaded hole 30, a threaded sleeve 12 is threadedly matched with the first threaded rod 9, a universal wheel 32 is installed below the base 1, and the lifting column 5 can move in the hollow column 4 through the threaded match between the second threaded rod 28 and the threaded hole 30, thereby raising the height of the fixing platform 6 to adapt to different usage requirements, and the universal wheel 32 can facilitate the staff to move the fixing and clamping device.

[0022] A limiting groove 29 is provided on the inner wall of the hollow column 4, and a limiting strip 31 is connected to the outer wall of the lifting column 5. A total of four limiting strips 31 are symmetrical about the axis of the lifting column 5 and are slidably connected to the limiting groove 29. When the lifting column 5 moves in the hollow column 4, the limiting strips 31 will move together in the limiting groove 29, thereby guiding and limiting the movement of the lifting column 5 to prevent the lifting column 5 from rotating.

[0023] A fixed platform 6 is connected to the lifting column 5, a sliding hole 23 is provided on the supporting column 3, a smooth rod 24 is connected below the fixed platform 6, the smooth rod 24 is slidably connected to the supporting column 3 through the sliding hole 23, and the movement of the fixed platform 6 is assisted by the sliding of the smooth rod 24 in the supporting column 3, so that the fixed platform 6 moves smoothly and the fixed platform 6 is prevented from tilting and causing the cylinder body to slide.

[0024] A first slide groove 7 is provided on the fixed platform 6, and a second slide groove 8 is provided on the fixed platform 6. A first threaded rod 9 is rotatably connected in the second slide groove 8, and a rotating wheel 10 is connected to one end of the first threaded rod 9. A moving block 11 is installed on the first threaded rod 9, and a threaded sleeve 12 is installed on the moving block 11. A connecting plate 13 is connected to the moving block 11, and a sliding rod 14 is slidably connected to the connecting plate 13. A clamping plate 15 is connected to one end of the sliding rod 14, and a connecting spring 16 is connected to one end of the sliding rod 14. One end of the connecting spring 16 is connected to the connecting plate 13, and a rubber pad 17 is connected to the clamping plate 15. The rubber pad 17 is provided with anti-skid patterns. The contact between the clamping plate 15 and the engine cylinder block is buffered by the rubber pad 17 to prevent the clamping plate 15 from scratching and damaging the cylinder block, and the rubber pad 17 can also increase the friction between the cylinder block and the cylinder block, thereby preventing the cylinder block from sliding.

[0025] A slider 18 is slidably installed in the first slide groove 7, and a threaded column 19 is connected to the slider 18. A pressure plate 20 is slidably connected to the threaded column 19. A fastening nut 21 is threadedly connected to the threaded column 19. A return spring 22 is connected below the pressure plate 20, and one end of the return spring 22 is connected to the slider 18. The slider 18 and the moving block 11 are both I-shaped and fit with the first slide groove 7 and the second slide groove 8 respectively. A motor 25 is installed on the mounting plate 2, and the output shaft of the motor 25 is connected to a first bevel gear 26, and the first bevel gear 26 is meshedly connected to the second bevel gear 27. The second bevel gear 27 is connected to a second threaded rod 28. By screwing the fastening nut 21, the fastening nut 21 presses down the pressure plate 20, prompting the pressure plate 20 to press and fix the edge of the engine cylinder block, thereby further fixing the cylinder block to prevent the cylinder block from sliding.

[0026] The working principle of the utility model is:

[0027] After placing the engine cylinder block on the fixed platform 6, the rotating wheel 10 is turned to rotate the first threaded rod 9, so that the moving block 11 moves along the first threaded rod 9 through the threaded sleeve 12, so that the clamping plate 15 contacts the cylinder block, thereby clamping and fixing the cylinder block. When the clamping plate 15 contacts the cylinder block, the clamping plate 15 pushes the sliding rod 14 to move, so that the sliding rod 14 can stretch the connecting spring 16, so that the clamping plate 15 can fit with the cylinder block through the rebound of the connecting spring 16. Then the staff pushes the slider 18 to move to adjust the position of the pressure plate 20 on the fixed platform 6, and tightens the fastening nut 21 to tighten the fastening nut. The nut 21 presses down the pressure plate 20, causing the pressure plate 20 to press and fix the edge of the engine cylinder body, thereby further fixing the cylinder body, and then starting the motor 25 to rotate the first bevel gear 26, and the first bevel gear 26 is engaged with the second bevel gear 27 to drive the second threaded rod 28 to rotate, so that the lifting column 5 can move in the hollow column 4 through the threaded cooperation between the second threaded rod 28 and the threaded hole 30, thereby raising the overall height of the fixed platform 6 to meet the usage requirements of different operators, and when the fixed platform 6 rises, the smooth rod 24 will slide together in the support column 3, so that the fixed platform 6 can move smoothly.
