Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment manufacturing technology, and in particular to a device for rotating and turning automobile frames during processing. Background Technology

[0002] The car frame is made up of two main beams and crossbeams riveted together. Before the car frame is riveted together, the car beams must be rotated 180° with the openings of the channel steel facing down. This is usually done manually. Since each car beam weighs 220 kilograms, the employees in this position must be "strongmen". However, manually rotating the car beams is inefficient and labor-intensive for the workers.

[0003] Chinese utility model patent (authorization announcement number: CN203996544U, name: vehicle frame tilting device) has a lifting mechanism installed on the top crossbeam of the frame, and a tilting frame provided below the lifting mechanism. The lifting mechanism is connected to the tilting frame. A tilting motor is fixed on the tilting frame, and a drive sprocket is fixed on the output shaft of the tilting motor. An outer swing arm and an inner swing arm are hinged on the tilting frame below the drive sprocket. The upper ends of the outer swing arm and the upper ends of the inner swing arm are hinged to the tilting frame by the same pin. An outer connecting rod is hinged to the middle of the outer swing arm, and an inner connecting rod is hinged to the middle of the inner swing arm. A first tension spring, a second tension spring, a third tension spring, and a fourth tension spring are fixed on the tilting frame. An outer steering sprocket is rotatably installed at the lower end of the outer swing arm, and an inner steering sprocket is rotatably installed at the lower end of the inner swing arm. A tilting chain is provided on the drive sprocket, the outer steering sprocket, and the inner steering sprocket. This utility model has the advantages of simple structure, stable and reliable operation, convenient use and low cost. However, due to the large size and heavy weight of the frame, the line of sight is obstructed during the relocation and hoisting process. In addition, its large inertia makes it difficult to control the travel route, which can easily lead to collisions / accumulation with people or objects, resulting in accidents.

[0023] like Figure 1 and 2 As shown, a device for flipping and processing an automobile frame includes a left support 1 and a right support 2. The left support 1 is fixed to the ground, and the right support 2 is slidably mounted on the ground and slides towards the left support 1 (sliding via a guide rail and rollers, with brakes on the rollers to lock the right support 2 onto the guide rails). A left clamping member is rotatably mounted on the left support 1, and a right clamping member is rotatably mounted on the right support 2. The left and right clamping members have the same structure and are both located between the left support 1 and the right support 2. A spring 3 is sleeved on the rotating shaft of the left clamping member. A locking block 4 is fixed on the rotating shaft. The locking block 4 is located at the end away from the right bracket 2. A limiting groove 5 is opened on the left bracket 1 to engage the locking block 4. The locking block 4 is slid out of the limiting groove 5 by the compression spring 3. The frame is fixed between the two brackets by the clamping device. Then, the grinding and deburring operation begins. After the front grinding is completed, the right bracket 2 is pushed to the left, causing the locking block 4 to slide out of the limiting groove 5 and rotate 180 degrees. The right bracket 2 is then retracted, causing the locking block 4 to engage in the limiting groove 5 and lock the rotating shaft. The operation can then continue. The structure is simple and easy to use, and the operation is safe and the work efficiency is high.

[0024] In this embodiment, as Figure 1 and 2 As shown, the right clamping component includes a crossbeam 6 and a support arm 7. The crossbeam 6 is rotatably mounted on the right bracket 2. The support arm 7 is used to insert into the steel tube at the end of the car frame. A retaining ring is installed on the rotating shaft of the right clamping component. The retaining ring is used to fix the rotating shaft of the right clamping component axially to prevent the right clamping component from shifting during the grinding process and affecting the grinding operation.

[0025] In this embodiment, as Figure 1 and 3 As shown, the groove opening of the limiting groove 5 is chamfered, and the locking block 4 smoothly engages with the limiting groove 5 through the chamfer. When in use, it can be rotated about 180 degrees without the need for precise control of the rotation angle to lock it, which reduces the difficulty of using the device.

[0026] In this embodiment, as Figure 2 and 4As shown, a threaded hole 9 is provided on the support arm 7 along its extension direction. The threaded hole 9 passes through the crossbeam 6. A bolt 10 is screwed onto the crossbeam 6. The screw-in end of the bolt 10 is tapered. A locking hole is provided at the top of the support arm 7. The locking hole is connected to the threaded hole 9. A locking block 11 is inserted into the locking hole. The locking block 11 enters and exits the locking hole through the tapered end of the bolt 10. The locking block 11 locks the frame fitted on the support arm 7, preventing the frame from jumping during the grinding process.

[0027] In this embodiment, as Figure 1 and 2 As shown, a force-adding rod 12 is inserted into the rotating shaft of the right clamping part, and the retaining ring is located between the right bracket 2 and the force-adding rod 12. The lever principle allows the worker to easily and effortlessly perform the flipping, reducing the worker's labor intensity.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
