Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic clamps, in particular to a multi-station hydraulic clamp for producing crankcases. Background Art

[0002] The crankcase is one of the important parts of a car. The crankcase includes an upper crankcase and a lower crankcase. The upper crankcase is cast as one piece with the cylinder block, and the lower crankcase is used to store lubricating oil and seal the upper crankcase, so it is also called the oil pan. The lower crankcase is subjected to very little force and is generally stamped from thin steel plates. Its shape depends on the overall layout of the engine and the capacity of the engine oil. During actual processing, the lower crankcase must be stably fixed to prevent the lower crankcase from moving or vibrating during processing, resulting in unstable processing quality and ensuring processing accuracy.

[0003] The publication number in the existing public technology is: CN212762319U. A double-station hydraulic clamp for crankcase processing comprises a base plate, a vertical plate is arranged on the rear side of the top of the base plate, a cross plate is arranged on the front side of the vertical plate, a mounting plate and a fixing plate are symmetrically arranged on the front sides of the cross plate, and the fixing plate is arranged between the mounting plate, a hydraulic cylinder is arranged between the mounting plate and the fixing plate, one end of the hydraulic cylinder is fixedly connected to the mounting plate, an output end of the hydraulic cylinder is fixedly connected to the fixing plate, a supporting plate is arranged on the rear side of the vertical plate, a motor box is arranged on the top of the supporting plate, and a motor is arranged in the motor box. The utility model has a simple structure and a reasonable design. The fixing plate is driven by the hydraulic cylinder to clamp and fix the crankcase, and during processing, the cross plate is driven by the motor to rotate the crankcase up and down, so that both sides can be processed after one clamping, and there is no need to load and unload again, which is highly practical.

[0004] However, the above patent still has certain disadvantages when in use: although the crankcase can be clamped and fixed by the fixing plate, the bottom of the crankcase lacks a supporting structure after clamping, and it is easy for the crankcase to break free from between the fixing plates due to the pressure from above during processing, resulting in the falling of the equipment and a threat to the safety of personnel. In addition, when the crankcase is being operated, the crankcase needs to be placed between the fixing plates. Due to the height difference between the fixing plates and the ground, it will be more laborious for personnel to carry it up, and manual operation also increases the operating risks of personnel. The overall safety of use is not very good.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0030] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0031] In one embodiment, a bottom plate 1, a horizontal plate 6 and a vertical plate 2, a vertical plate 2 is fixedly installed at a position on one side of the top of the bottom plate 1, a turntable 16 is provided in the middle position of the surface of the vertical plate 2, one end of the turntable 16 passes through one side of the vertical plate 2 and is connected to the first motor 10, lifting boxes 9 are symmetrically installed on both sides above the turntable 16 at the top position of the surface of the vertical plate 2, a brake motor 13 is fixedly installed at one side of the inside of the lifting box 9, a winding drum 11 is connected to one end of the brake motor 13, a cable 12 is wound and connected to the outer surface of the winding drum 11, one end of the cable 12 passes through one side of the lifting box 9 and is connected to a connecting rod 14, a clamp 15 is fixedly installed at the bottom position of the connecting rod 14, an adjusting groove 20 is opened in the middle position of the surface of the vertical plate 2 below the turntable 16, a threaded rod 19 is provided in the middle position inside the adjusting groove 20, a bearing platform 3 is sleeved on the outer periphery of the threaded rod 19, and one end of the threaded rod 19 passes through one side of the adjusting groove 20 and is connected to the second motor 21.

[0032] In one embodiment, a plurality of groups of limiting grooves 5 are symmetrically formed on the surfaces of both ends of the transverse plate 6 .

[0033] In one embodiment, a receiving groove 8 is provided on one side of the limiting groove 5 on the surface of the vertical plate 2 , a second hydraulic rod 17 is fixedly installed deep inside the receiving groove 8 , and a limiting plate 18 is fixedly installed at one end of the second hydraulic rod 17 .

[0034] In one embodiment, the size of the limit plate 18 is the same as the size of the limit slot 5. The same size ensures that the limit plate 18 can be smoothly moved to the internal position of the limit slot 5 to limit the cross plate 6, ensuring that it will not rotate when the crankcase is processed.

[0035] In one embodiment, a cavity is opened inside the base plate 1 for installing the second motor 21 .

[0036] In one embodiment, a groove is provided on the surface of the support platform 3, and the shape of the groove is the same as the shape of the crankcase surface. The support platform 3 is provided to support and limit the bottom of the crankcase to prevent the clamping plate 7 from falling off due to lack of support at the bottom.

[0037] In one embodiment, the cable 12 is made of metal material, which ensures the strength of the cable 12 during use.

[0038] Working principle: In actual use, when the crankcase required is to be produced and processed, the clamp 15 can be used to clamp the top two sides of the crankcase, and then the brake motor 13 inside the lifting box 9 is controlled to drive the winding drum 11 to rotate. At this time, the winding drum 11 can wind the cable 12 around the surface of the winding drum 11, and then lift the crankcase as a whole, which is convenient for the subsequent clamping operation of the clamping plate 7, and the bottom support platform 3 will also move up synchronously while the clamping rises. This can not only reduce the difficulty and strength of crankcase lifting, but also avoid damage to the crankcase when it falls off, and can effectively protect the crankcase. In the subsequent processing of the crankcase, it can also support the bottom of the crankcase, which can avoid the pressure from the top of the crankcase causing the crankcase to fall off from between the clamping plates 7. The fixing effect of the crankcase is improved to ensure the processing effect. Then, after the crankcase is lifted to the specified position, the ejection of the first hydraulic rod 4 on both sides of the cross plate 6 can drive the clamping plates 7 to approach each other, thereby realizing the clamping and fixing operation of the crankcase, which is convenient for subsequent processing. Then, after the clamping is completed, the ejection of the second hydraulic rod 17 on the side can make the surface limit plate 18 inserted into the limit groove 5 on the surface of the cross plate 6, thereby fixing the cross plate 6 to prevent movement during processing that affects the processing accuracy. Then, after one side is processed, all structures are evacuated, and the rotation of the turntable 16 can drive the cross plate 6 to flip, so that the other side of the crankcase faces upward, which is convenient for its secondary processing. The crankcase does not need to be disassembled to complete the comprehensive processing operation, which effectively improves the overall processing effect. The device as a whole has the advantages of convenient loading and unloading, high processing load and high safety.
