Description
Technical Field
[0001] This utility model relates to the field of oil pan processing technology, specifically to a gripper structure applicable to oil pans. Background Technology
[0002] The oil pan is the lower part of the crankcase, also known as the lower crankcase. Located at the bottom of the engine, it is bolted to the crankcase, with gaskets at the connection to ensure a seal. It is mostly made of stamped thin steel sheet, while more complex models are cast iron or aluminum alloy. It has an internal oil baffle, a dipstick on the side, and a drain plug at the bottom. Its main functions include storing lubricating oil, sealing the crankcase, dissipating heat, settling impurities, and providing lubrication.
[0003] During assembly and maintenance, the oil pan needs to be fixed with clamps. Due to the complex external structure of the oil pan, there are currently problems such as difficulty in clamping and damage to the oil pan during the clamping process. In addition, conventional clamps usually only have a clamping function, which is relatively simple. After clamping the oil pan, the angle of the oil pan cannot be adjusted, resulting in poor flexibility. Therefore, we propose a claw structure suitable for oil pans to solve the existing shortcomings. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1-5As shown, this utility model provides a technical solution: a gripper structure suitable for oil pans, including a base 1, a movable plate 2 slidably connected to the top of the base 1, an adjustment component 3 between the base 1 and the movable plate 2, connecting rods 4 fixedly connected to the four corners of the top of the movable plate 2, an mounting plate 5 fixedly connected to the top of the connecting rods 4, an oil pan workpiece 6 mounted on the top of the mounting plate 5, a first positioning block 7 fixedly connected to one side of the upper surface of the mounting plate 5, two second positioning blocks 8 fixedly connected to the other side of the upper surface of the mounting plate 5, a gripper assembly 9 provided on the bottom side of the mounting plate 5, mounting holes 10 opened around the surface of the base 1, the outer side of the first positioning block 7 fitting against the outer side of the oil pan workpiece 6, and the outer side of the second positioning block 8 fitting against the outer side of the oil pan workpiece 6.
[0023] In use, first fix the base 1 through the mounting hole 10, place the oil pan workpiece 6 on the top of the mounting plate 5, and make the two sides of the oil pan workpiece 6 fit against the first positioning block 7 and the second positioning block 8 respectively. Then, clamp the other two sides of the oil pan workpiece 6 through the gripper assembly 9 to fix the oil pan workpiece 6, which makes it convenient for personnel to clamp the oil pan workpiece 6. After the oil pan workpiece 6 is fixed, the adjustment assembly 3 can be used to drive the oil pan workpiece 6 to swing back and forth to adjust the angle of the oil pan workpiece 6.
[0024] like Figure 1 and Figure 2 As shown, the adjustment assembly 3 includes a guide block 301, a slider 302, a semi-circular toothed plate 303, a fixed plate 304, a worm gear 305, and a drive motor 306. The bottom end of the guide block 301 is fixedly connected to the top end of the base 1. The top end of the slider 302 is fixedly connected to the bottom end of the movable plate 2. The bottom of the slider 302 is slidably connected to the outside of the guide block 301. The bottom end of the semi-circular toothed plate 303 is fixedly connected to the top end of the base 1. There are two fixed plates 304. The top ends of the fixed plates 304 are fixedly connected to both sides of the bottom end of the movable plate 2. The worm gear 305 is rotatably connected between the two fixed plates 304. The worm gear 305 meshes with the semi-circular toothed plate 303 of the fixed plate 304. One end of the drive motor 306 is fixedly connected to the outside of one of the fixed plates 304. The output shaft of the drive motor 306 is fixedly connected to one end of the worm gear 305.
[0025] The angle of the oil pan can be adjusted after clamping by the setting adjustment component 3. By starting the drive motor 306, the worm 305 is driven to rotate. Since the worm 305 meshes with the semi-circular toothed plate 303, and with the guiding effect of the slider 302 and the guide block 301, the worm 305 can be driven to move along the semi-circular toothed plate 303, thereby driving the movable plate 2 to rotate and adjust the angle of the oil pan workpiece 6.
[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the gripper assembly 9 includes a sliding plate 901, a sliding plate 902, a positioning claw 903, a protective pad 904, a rotating disk 905, a slide groove 906, a sliding rod 907, a sliding rod 908, a drive cylinder 909, and a guide rail 910. The bottom end of the sliding plate 901 is slidably connected to the top end of the mounting plate 5, and the bottom end of the sliding plate 902 is slidably connected to the top end of the mounting plate 5. There are two positioning claws 903, and the bottom ends of the two positioning claws 903 are respectively fixedly connected to one end of the sliding plate 901 and the sliding plate 902. The outer side of the protective pad 904 is fixedly connected to the top end of the positioning claw 903. The top end of the rotating disk 905 is rotatably connected to the mounting plate 5. At the bottom end of plate 5, a groove 906 is formed inside the rotating disk 905. The bottom end of slide rod 1 907 is fixedly connected to the top end of slide plate 1 901, and the bottom end of slide rod 2 908 is fixedly connected to the top end of slide plate 2 902. Slide rod 2 908 and slide rod 1 907 are respectively located inside the two grooves 906. The bottom end of drive cylinder 909 is fixedly connected to the top end of movable plate 2, and the output shaft of drive cylinder 909 is fixedly connected to one end of slide plate 1 901. There are two guide rails 910. The bottom end of guide rail 910 is fixedly connected to the top end of movable plate 2, and the top ends of the two guide rails 910 are slidably connected to slide plate 1 901 and slide plate 2 902 respectively.
[0027] By starting the drive cylinder 909, the sliding plate 901 moves horizontally. In conjunction with the sliding rod 907, the sliding groove 906, the rotating disk 905, and the sliding rod 908, the sliding plate 901 and the sliding plate 902 can be moved simultaneously, so that the two positioning claws 903 abut against the other two sides of the oil pan workpiece 6.
[0028] Working principle: In use, firstly, fix the base 1 through the mounting hole 10, place the oil pan workpiece 6 on the top of the mounting plate 5, and make the two sides of the oil pan workpiece 6 fit against the first positioning block 7 and the second positioning block 8 respectively. Then, start the drive cylinder 909 to drive the sliding plate 901 to move horizontally, and at the same time make the sliding rod 907 slide in the sliding groove 906, which in turn drives the rotating disk 905 to rotate, and makes the sliding rod 908 also slide in the sliding groove 906. This can simultaneously drive the sliding plate 901 and the sliding plate 902 to move, which can drive the positioning claws 903 at one end of the sliding plate 901 and the sliding plate 902 to move towards the oil pan workpiece 6. Finally, the two positioning claws 903 abut against the other two sides of the oil pan workpiece 6, fixing the oil pan workpiece 6, which is convenient for personnel to clamp the oil pan workpiece 6. During the clamping process, the protective pad 904 can protect the oil pan workpiece 6 to avoid injury.
[0029] When the angle of the oil pan workpiece 6 needs to be adjusted after it is fixed, the drive motor 306 is started to rotate, which drives the worm gear 305 to rotate. Since the worm gear 305 meshes with the semi-circular toothed plate 303, and with the guiding effect of the slider 302 and the guide block 301, the worm gear 305 can be moved along the semi-circular toothed plate 303, which in turn drives the movable plate 2 to rotate, thereby causing the oil pan workpiece 6 to swing back and forth, adjusting the angle of the oil pan workpiece 6 and improving the flexibility of the device.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
