[0002] The automobile engine is a device that provides power for the car. It is the heart of the car and determines the car's power, economy, stability and environmental protection. According to different power sources, automobile engines can be divided into diesel engines, gasoline engines, electric car motors and hybrid power, etc. The main body of the engine is the supporting frame for installing pistons, crankshafts and other parts and accessories. It connects each cylinder and crankcase into one. The part at the bottom of the cylinder block used to install the crankshaft is called the crankcase. The crankcase is divided into an upper crankcase and a lower crankcase.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figures 1 to 4 As shown, this embodiment provides a fixture for oil pan processing, including:

[0031] A bottom plate 1, with a plurality of slide grooves 2 evenly arranged at four corners of the bottom plate 1, the slide grooves 2 are arranged opposite to each other and extend from the middle of the bottom plate 1 to the outside;

[0032] A plurality of positioning components, the positioning components comprising a sliding column 3, the sliding column 3 is slidably connected to the inside of the sliding groove 2;

[0033] A plurality of clamping components are evenly fixed to the edge of the bottom plate 1, and the clamping components include a hydraulic telescopic rod 4, the bottom of the hydraulic telescopic rod 4 is fixed to the bottom plate 1, and the top movable end of the hydraulic telescopic rod 4 is connected to a clamping head 5;

[0034] The rotating assembly is fixed to the center of the bottom surface of the bottom plate 1;

[0035] The supporting assembly is disposed below the bottom plate 1 and is fixedly connected to the rotating assembly.

[0036] When the oil pan is clamped by the clamping tool of the present application, the oil pan is first placed at the center of the bottom plate 1, and then the sliding posts 3 are respectively moved inwards until the outer walls of the sliding posts 3 abut against the edge of the oil pan, and a plurality of sliding posts 3 jointly define the plane position of the oil pan; then the clamping assembly is adjusted, and then the clamping assembly is retracted so that the clamping head 5 abuts against the top surface of the oil pan to limit the vertical position of the oil pan, thereby fixing the oil pan, and the sliding posts 3 can move closer to and away from the center of the bottom plate 1, and can also adjust the distance from the center of the bottom plate 1 respectively, so as to adapt to oil pans of different sizes and shapes, and the clamping assembly can also be retracted to adapt to oil pans of different bottom thicknesses. Therefore, the present application can adapt to oil pans of different shapes and sizes and clamp them firmly; the rotating assembly can drive the entire bottom plate 1 to rotate, so that when the oil pan is processed, the person can process it from different angles without moving; the supporting assembly can increase the height of the clamping tool to adapt to the height of the person, so as to facilitate the processing operation.

[0037] To further optimize the solution, the positioning assembly also includes a movable block 6, which is fixedly connected to the bottom of the sliding column 3. A movable groove 7 is fixedly connected to the bottom of the base plate 1 corresponding to the movable block 6. The movable block 6 is slidably connected in the movable groove 7. The center thread of the movable block 6 is connected to a screw rod 8. One end of the screw rod 8 is rotatably connected to the end plate of the movable groove 7, and the other end extends out of the movable groove 7 to be transmission-connected to the output end of the movable motor 9. The movable motor 9 is fixedly connected to the bottom surface of the base plate 1.

[0038] The movable motor 9 drives the screw 8 to rotate, so that the movable block 6 slides in the movable groove 7, and then drives the sliding column 3 to slide in the sliding groove, so that the sliding column 3 gradually approaches or moves away from the edge of the oil pan, forming a position limit or relaxation in the plane direction of the oil pan.

[0039] To further optimize the solution, the clamping head 5 and the top of the hydraulic telescopic rod 4 are movably connected through a fixed block 10 and an extension rod 18. The fixed block 10 is fixedly connected to the top of the hydraulic telescopic rod 4, and the extension rod 18 is threadedly connected to the middle part of the fixed block 10. One end of the extension rod 18 is fixedly connected to a rotating handle 11, and the other end is fixedly connected to the clamping head 5.

[0040] The clamping head 5 is fixedly connected to one end of the extension rod 18. The extension rod 18 can be moved in the fixed block 10 by rotating the rotating handle 11 at the other end of the extension rod 18, thereby changing the distance between the clamping head 5 and the center of the bottom plate 1, so as to facilitate adjustment for oil pans of different sizes, so that the clamping block is located at the top of the oil pan, so that the clamping head 5 can clamp the oil pan on the bottom plate 1 after the hydraulic telescopic rod 4 is contracted.

[0041] According to a further optimized solution, the outsides of the clamping head 5 and the sliding column 3 are wrapped with buffer pads.

[0042] The buffer pad can protect the oil pan and the clamping head 5 or the sliding column 3 from hard collision or wear, thereby extending the service life of the clamp and ensuring product quality.

[0043] According to a further optimized solution, the support assembly includes a support plate 12 , a plurality of support columns 13 are circumferentially fixedly connected to the bottom of the support plate 12 , and the rotating assembly is fixedly connected to the support plate 12 .

[0044] Furthermore, when the support plate 12 and the base plate 1 rotate, the structures below do not interfere with each other. On the one hand, the support assembly increases the height of the fixture workbench to facilitate processing operations, and on the other hand, it provides a position for the installation of the rotating motor 15.

[0045] A further optimized solution is that the rotating assembly includes a rotating shaft 14 and a rotating motor 15, the output end of the rotating motor 15 is transmission connected to the rotating shaft 14, the top of the rotating shaft 14 is fixedly connected to the center of the bottom surface of the base plate 1, the rotating motor 15 is fixedly connected to the bottom end of the support plate 12, and the bottom of the rotating shaft 14 passes through the support plate 12 and is transmission connected to the rotating motor 15.

[0046] The rotating motor 15 drives the rotating shaft 14 to rotate, thereby rotating the bottom plate 1, so that the staff can process the oil pan from different angles.

[0047] According to a further optimized solution, the rotating shaft 14 and the supporting plate 12 are rotatably connected via a bearing 17 .

[0048] The use of the bearing 17 for rotational connection reduces the friction force during the rotation process, thus saving energy and effort.

[0049] According to a further optimized solution, a plurality of fixing rods 16 are fixedly connected to the bottom surface of the bottom plate 1 , and the fixing rods 16 extend from the center of the bottom plate 1 to the edge of the bottom plate 1 .

[0050] The fixing rods 16 increase the strength of the bottom plate 1 and prevent the bottom plate 1 from bending.
