Description

Technical Field

[0001] This utility model relates to mechanical positioning and clamping, and in particular to an automatic flipping and repositioning device, belonging to the field of mechanical technology. Background Technology

[0002] In the assembly and production of mechanical parts, there are many scenarios where the workpieces are quite large. For example, in one scenario, the workpiece is a conical cylinder, with varying sizes and weights ranging from 1000kg to 2000kg. The workpiece needs to be operated in multiple orientations, including horizontal, vertical, and oblique. Current workshop operations use overhead cranes to lift the workpiece, but this method has several drawbacks: first, the work area must be equipped with an overhead crane; second, the workpiece is not fixed during operation, and despite its weight, there is a risk of tipping over, posing a safety hazard; third, the workpiece needs to be suspended during oblique operations, resulting in instability; and fourth, it requires a significant amount of time to occupy the overhead crane. Therefore, for this type of application, it is necessary to develop corresponding devices to meet the operational requirements. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic flipping and repositioning device.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: an automatic flipping and repositioning device includes a base, a hinge seat fixedly installed at one end of the base, the body end of an electric push rod with self-locking mechanism hinged to the hinge seat, a U-shaped seat fixedly installed at the other end of the base, a rotating shaft tightly fitted at both ends to the inner ring of a bearing, the outer ring of the bearing tightly fitted to a bearing seat, the bearing seat fixedly connected to the U-shaped seat, a swing arm fixedly connected to the rotating shaft, the actuating end of the electric push rod hinged to the swing arm near its end, a flipping table fixedly connected to the rotating shaft, and at least two sets of movable workpiece fixing mechanisms arranged in the front-rear direction on the flipping table. It includes a lower arc-shaped groove seat and an upper arc-shaped groove seat. Both the lower and upper arc-shaped groove seats have arc-shaped grooves. Right-angle grooves are opened at the outer corners of the upper two sides of the lower arc-shaped groove seat. The end of the tension bolt is hinged in the right-angle groove through a hinge shaft in the horizontal front-back direction. The upper arc-shaped groove seat has side opening grooves on both sides. After the workpiece is placed on the lower arc-shaped groove seat, the tension bolt enters the opening groove from the side and is fixed together by the nut. T-shaped grooves are opened on both sides of the table surface of the turning table. The lower two sides of the lower arc-shaped groove seat are integrally provided with feet. Bolt holes are opened on the feet. The T-bolts located in the T-shaped grooves pass through the bolt holes and are tightened by nuts.

[0005] Furthermore, rubber pads are fixedly installed inside the arc-shaped grooves of both the upper and lower arc-shaped grooves.

[0006] Furthermore, a rear positioning seat is fixedly installed at the rear of the tilting table, and two bolts are fixedly connected to the front end face of the lower arc-shaped slot seat at the frontmost part. The front baffle passes through two holes and is mounted on the bolts. Positioning nuts are screwed onto the bolts at both the front and rear of the front baffle.

[0007] Furthermore, the workpiece fixing mechanism consists of three sets.

[0008] Furthermore, four rectangular hoisting columns are fixedly installed on the front and rear sides of the base.

[0016] The following description of the device is based on the tilting table as the horizontal direction.

[0017] An automatic flipping and repositioning clamping device includes a base 1. Four rectangular lifting columns 11 are fixedly installed on the front and rear sides of the base, allowing the device to move the workpiece to the next process. A hinge seat (not shown in the figure) is fixedly installed at one end of the base. The body end of a self-locking electric push rod 2 is hinged to the hinge seat. A U-shaped seat 3 is fixedly installed at the other end of the base. Both ends of a rotating shaft 4 are tightly fitted into the inner rings of bearings 6, and the outer rings of the bearings are tightly fitted into bearing seats 7. The bearing seats are fixedly connected to the U-shaped seat 3. A swing arm 5 is fixedly connected to the rotating shaft 4. The actuating end of the electric push rod 2 is hinged to the swing arm near its end. A flipping table 8 is fixedly connected to the rotating shaft. At least two sets of movable workpiece fixing mechanisms 9 are arranged in the front-rear direction on the flipping table. In this embodiment, there are three sets of workpiece fixing mechanisms. The lower arc-shaped groove seat 902 and the upper arc-shaped groove seat 901 are all equipped with rubber pads 906. This prevents the workpiece from being compressed and causing quality problems. Both the lower and upper arc-shaped groove seats have arc-shaped grooves. The upper two outer corners of the lower arc-shaped groove seat have right-angle grooves 903. The end of the tension bolt 905 is hinged in the right-angle groove through a hinge shaft in the horizontal front-back direction. The upper arc-shaped groove seat has side opening grooves 904 on both sides. After the workpiece is placed on the lower arc-shaped groove seat, the tension bolt 905 enters the opening groove from the side and is fixed together with nuts. T-shaped grooves 12 are provided on both sides of the table surface of the turning table. The lower two sides of the lower arc-shaped groove seat are integrally provided with feet 907. Bolt holes are provided on the feet. T-bolts 13 located in the T-shaped groove pass through the bolt holes and are tightened by nuts. A rear positioning seat 10 is fixedly installed at the rear of the tilting table. Two bolts 15 are fixedly connected to the front end face of the lower arc-shaped slot seat at the frontmost position. The front baffle 14 passes through two holes and is threaded onto the bolts. Positioning nuts are screwed onto the bolts at both the front and rear of the front baffle. Multiple sets of workpiece fixing mechanisms can be manufactured for workpieces of different specifications. During use, the corresponding workpiece corresponds to the corresponding workpiece fixing mechanism.

[0018] In this application, the electric linear actuator is model LAP120-800-TS, manufactured by a company in Shandong Province. It is a standard toothed screw actuator with self-locking function and a positional accuracy of 0.1mm. The effective stroke is 800mm, the rated output is 90kN, the motor power is 7.5kW, and the rated speed is 22mm / s. In this device, corresponding proximity switches can be installed at the horizontal and vertical positions of the tilting table to control the electric linear actuator to stop.

[0019] When using this device to load workpieces, select the corresponding workpiece fixing mechanism for different workpieces and fix it to the tilting platform with T-bolts and nuts. The rear end of the workpiece rests on the rear positioning seat. Loosen the nut on the tension bolt to remove the upper arc-shaped groove seat. Hoist the workpiece onto the lower arc-shaped groove seat and then install the upper arc-shaped groove seat. Tighten the tension bolt with the nut. Then, insert the front baffle into the two bolts and adjust the positioning nut so that the front baffle presses against the front end face of the workpiece.

[0020] During operation, the rotating shaft is driven by an electric push rod to rotate the tilting table and achieve the required angle.

[0021] After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications.
