DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses an oil pan machining flip fixture. Figure 1-3 , a turning fixture for oil pan processing, comprises a bottom plate 1, a top outer wall of one end of the bottom plate 1 is fixedly connected with a fixed seat 2, a top outer wall of the end of the bottom plate 1 away from the fixed seat 2 is provided with a movable seat 3, the movable seat 3 and the middle inner wall of the fixed seat 2 near the top are rotatably connected with a rotating shaft 4, the two ends of the rotating shaft 4 respectively penetrate the movable seat 3 and the fixed seat 2, the opposite ends of the two rotating shafts 4 are fixedly connected with a clamping plate 5 for clamping the oil pan, a cylinder 14 is fixedly installed on the bottom outer wall of the movable seat 3, the output end of the cylinder 14 is fixedly connected to the outer wall of the fixed seat 2, the outer wall of the fixed seat 2 is installed with a turning mechanism for driving the clamping plate 5 to drive the oil pan to rotate, the turning mechanism comprises a worm gear 8 fixedly connected to one end of a rotating shaft 4 away from the clamping plate 5, the outer wall of the fixed seat 2 is fixedly connected with two shaft seats 9, the outer walls opposite to the two shaft seats 9 are rotatably connected with a worm 10, and the worm 10 is meshed with the worm wheel 8.

[0021] The flipping mechanism also includes a servo motor 11 fixedly mounted on the outer wall of the fixing seat 2 through a bracket. The end of the output shaft of the servo motor 11 passes through a shaft seat 9 and is fixedly connected to one end of the worm 10 .

[0022] The top outer wall of the bottom plate 1 is fixedly connected with two guide rails 12 , one end of the two guide rails 12 abuts against the outer wall of the fixed seat 2 , the outer walls of the two guide rails 12 are slidably connected with sliders 13 , and the movable seat 3 is fixedly connected to the top outer walls of the two sliders 13 .

[0023] The opposing outer walls of the two clamping plates 5 are installed with clamping blocks 6, and the opposing outer walls of the two clamping blocks 6 are provided with a plurality of friction grooves 7. The clamping blocks 6 are made of elastic rubber material and have a certain degree of softness. The plurality of friction grooves 7 can be embedded with the plurality of uneven edges of the oil pan, thereby increasing the friction force and firmly fixing the oil pan.

[0024] A plurality of fixing legs 15 are fixedly connected to the longer outer walls of the bottom plate 1 , and the plurality of fixing legs 15 are used to fix and support the bottom plate 1 .

[0025] The implementation principle of the oil pan processing flip fixture of the embodiment of the present application is as follows: when in use, the bottom plate 1 is fixed to a suitable processing position by bolts through a plurality of fixing feet 15, and then the oil pan is placed between the two clamping plates 5, and the cylinder 14 is started. The output end of the cylinder 14 contracts, and the cylinder 14 drives the movable seat 3 to move close to the fixed seat 2. When the movable seat 3 moves, it drives the two slide blocks 13 to slide on the outer walls of the two guide rails 12, which plays a limiting role, so that the movable seat 3 always moves linearly and stably, and it is difficult to shake. When the distance between the two clamping plates 5 is reduced, it drives the two clamping blocks 6 to clamp the two ends of the oil pan. Since the clamping blocks 6 have a certain degree of flexibility, the clamping blocks 6 can cover the end shape of the oil pan according to the end shape of the oil pan, increase the contact area with the two ends of the oil pan, and then firmly clamp the oil pan. At the same time, the plurality of friction lines 7 can be embedded with the plurality of uneven edges of the oil pan, further increasing the friction force, and preventing the oil pan from falling off. At this time, the oil pan can be processed and drilled by external processing equipment;

[0026] When one side of the oil pan is processed, the servo motor 11 can be started through the flipping mechanism, and the output end of the servo motor 11 drives the worm 10 to rotate on the inner walls of the two shaft seats 9, and then the worm 10 drives the worm wheel 8 engaged with it to rotate, and the worm wheel 8 drives the clamping plate 5 to rotate through the rotating shaft 4. Since the two clamping plates 5 and the oil pan are clamped to form a whole, the rotation of one clamping plate 5 causes the two clamping plates 5 to drive the oil pan to flip, and when the surface of the oil pan to be processed is flipped to the top, processing can be carried out, thereby achieving multi-faceted processing of the oil pan with one fixation.
