Description

Technical Field

[0001] This utility model relates to the field of positioner tilting table technology, specifically to an adjustable-angle positioner tilting table. Background Technology

[0002] Adjustable angle flipping tables are core equipment used in industrial manufacturing to adjust the posture of workpieces. Their background technology involves multiple disciplines such as mechanical design, automation control, and materials science. They aim to solve the limitations of traditional equipment in terms of flexibility, precision, safety, and efficiency. Early positioners were mostly manual or simple two-position flipping devices, which relied on manual operation and could not be linked with robot systems, resulting in low welding or assembly efficiency. In situations where only two-position flipping is required, traditional equipment cannot achieve automated program control, while introducing fully automatic positioners would result in cost waste.

[0003] According to Chinese patent document CN218051132U, a welding positioner flipping device includes a base with symmetrically arranged frames on the base. The bottom end of the frame is connected and fixed to the bottom end of a hydraulic pump, and the upper end of the hydraulic pump is connected and fixed to a mounting block. A motor is connected and fixed to the mounting block, and the output end of the motor is connected and fixed to one end of a turntable. The other end of the turntable is connected and fixed to a main positioning device. Auxiliary positioning devices are symmetrically arranged on the main positioning device. A sliding groove is opened at the opposite end of the frame. This structure allows for the replacement of clamping components, making the device suitable for clamping various welding parts of different specifications. After replacing the clamping components, the nut can be self-locked to prevent the nut from loosening during welding and causing danger.

[0004] The device is fixed by manually rotating the nut during use, which is inconvenient. After the angle is adjusted, the motor needs to be continuously powered to ensure that the position is fixed after rotation, resulting in energy waste. Utility Model Content

[0005] This invention provides an adjustable-angle positioner tilting table, which can effectively solve the problems in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An adjustable-angle positioner tilting platform includes a mounting base. Mounting brackets are fixedly connected to both sides of the mounting base's surface. A rotating shaft is rotatably connected between the two mounting brackets. A fixed base for fixing the positioner is fixedly connected to the outside of the rotating shaft. A motor for adjusting the angle of the fixed base is fixedly connected to the surface of one of the mounting brackets. The end of the rotating shaft near the motor extends through to the outside of the mounting bracket and is fixedly connected to the motor's output end. A locking mechanism is fixedly connected to the opposite side surfaces of the two mounting brackets. A rotating mechanism is provided on both the left and right sides near the fixed base. A protective mechanism is provided between the rotating mechanism and the locking mechanism.

[0007] Preferably, the rotating mechanism includes a fixed disk, four extension rods arranged in a circular array are fixedly connected to one side surface of the fixed disk, a friction disk for friction is fixedly connected to one end of the multiple extension rods away from the fixed disk, and two connecting rods are fixedly connected to the same side surface of the fixed disk and the extension rods.

[0008] Preferably, the locking mechanism includes an annular connecting block with a cavity inside. A first clamping plate and a second clamping plate for locking the friction disc are slidably connected inside the annular connecting block. Four hydraulic telescopic rods for moving the first clamping plate and the second clamping plate are arranged in a circular array between the outer walls of the first clamping plate and the inner wall of the annular connecting block. An oil tank for storing hydraulic oil is fixedly connected to the top of the mounting frame. A cylinder is fixedly connected to the outer wall of the oil tank, with the extended end of the cylinder penetrating into the interior of the oil tank. A hydraulic oil pipe is provided between the oil tank and the annular connecting block. The end of the hydraulic oil pipe away from the oil tank penetrates into the interior of the annular connecting block and is fixedly connected to the hydraulic telescopic rods. A scale for viewing the rotation angle is fixedly connected to the outer wall of the annular connecting block near the fixed disc. An annular push plate is fixedly connected to the surface of the second clamping plate near the fixed disc.

[0009] Preferably, the friction disc is located inside the annular connecting block and between clamping plate one and clamping plate two.

[0010] Preferably, the protection mechanism includes a connecting ring with two symmetrically formed mounting grooves on its surface. Two springs are symmetrically arranged on the inner wall of each mounting groove, and each spring has a stop plate at its end away from the inner wall of the mounting groove. Two sliding plates are fixedly connected to the outer wall of the connecting ring, and the sliding plates are slidably connected inside the annular connecting block. The sliding plates have an L-shaped cross-section. An annular push plate presses against the surface of the shorter end of the sliding plate. Two symmetrical limiting rods are slidably connected inside the connecting ring, and both ends of the limiting rods extend to the outside of the connecting ring. One end of the connecting ring abuts against the surface of the annular push plate.

[0011] Preferably, the connecting rod is sleeved between the two abutment plates, and two limiting grooves are formed on the surface of the fixed plate near the limiting rod.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: This utility model utilizes a locking mechanism composed of a cylinder, hydraulic telescopic rod, clamping plate, and friction disc. After angle adjustment, the rotating shaft can be mechanically locked and fixed. Even after the motor is powered off, the positioner remains stable, avoiding the energy waste of continuous motor power supply in traditional equipment. This reduces manual operation steps, improves ease of use, and the dial can intuitively display the rotation angle between the rotating shaft and the fixed base. Operators can accurately control the positioner's posture, preventing workpiece misalignment or equipment damage caused by uncontrolled angle.

[0013] This utility model uses a spring and abutment in the protection mechanism, along with a pressure sensor in the mounting slot, to monitor the weight of the positioner in real time. When the weight exceeds the upper limit of the locking mechanism, it can provide an early warning to prevent accidental rotation. The motor drives the rotating shaft to rotate, which can be linked with the robot welding and assembly system. It replaces the traditional manual simple flipping device, reduces human intervention, and improves overall work efficiency. Attached Figure Description

[0016] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments: like Figure 1As shown, this utility model provides an adjustable angle positioner tilting platform, including a mounting base 1. Mounting brackets 2 are fixedly connected to both sides of the surface of the mounting base 1. A rotating shaft 8 is rotatably connected between the two mounting brackets 2. A fixed base 6 for fixing the positioner is fixedly connected to the outside of the rotating shaft 8. A motor 7 for adjusting the angle of the fixed base 6 is fixedly connected to the surface of one of the mounting brackets 2. The end of the rotating shaft 8 near the motor 7 extends to the outside of the mounting bracket 2 and is fixedly connected to the output end of the motor 7. A locking mechanism 3 is fixedly connected to the opposite side of the surfaces of the two mounting brackets 2. A rotating mechanism 5 is provided on both the left and right sides near the fixed base 6. A protective mechanism 4 is provided between the rotating mechanism 5 and the locking mechanism 3. First, the positioner is fixed on the fixed base 6. The motor 7 drives the rotating shaft 8 and the fixed base 6 to rotate, adjusting the angle of the positioner. After the angle is adjusted, the locking mechanism 3 fixes the device 8 and the fixed base 6, ensuring that the position of the positioner will not change after the motor 7 is powered off.

[0017] like Figure 2 As shown, the rotating mechanism 5 includes a fixed disk 51. Four extension rods 53 arranged in a circular array are fixedly connected to one side surface of the fixed disk 51. The ends of the extension rods 53 away from the fixed disk 51 are fixedly connected to a friction disk 52 for friction. Two connecting rods 54 are fixedly connected to the same side surface of the fixed disk 51 and the extension rods 53. The fixed disk 51 is fixedly connected to the rotating shaft 8. When the rotating shaft 8 rotates, it drives the rotating mechanism 5 to rotate together. The friction disk 52 is annular, and the diameter of the middle of the annulus is larger than the diameter of the rotating shaft 8. The friction disk 52 is located inside the locking mechanism 3 and provides a large frictional force to fix the rotating shaft 8.

[0018] like Figure 3 As shown, the locking mechanism 3 includes an annular connecting block 31, which has an internal cavity. Inside the annular connecting block 31, clamping plates 32 and 33 for locking the friction disc 52 are slidably connected. Four hydraulic telescopic rods 34 for moving clamping plates 32 and 33 are arranged in a circular array between the outer walls of clamping plates 32 and 33 and the inner wall of the annular connecting block 31. An oil tank 36 for storing hydraulic oil is fixedly connected to the top of the mounting frame 2. The outer surface of the oil tank 36... A cylinder 37 is fixedly connected to the wall, and the extended end of the cylinder 37 extends into the interior of the oil tank 36. A hydraulic oil pipe 39 is provided between the oil tank 36 and the annular connecting block 31. The end of the hydraulic oil pipe 39 away from the oil tank 36 extends into the interior of the annular connecting block 31 and is fixedly connected to the hydraulic telescopic rod 34. A scale 38 for viewing the rotation angle is fixedly connected to the outer wall of the annular connecting block 31 near the fixed plate 51. An annular push plate 35 is fixedly connected to the surface of the clamping plate 33 near the fixed plate 51.

[0019] The friction disc 52 is located inside the annular connecting block 31 and between clamping plate 1 32 and clamping plate 2 33. The cylinder 37 compresses the internal space of the oil tank 36, and the hydraulic oil in the oil tank 36 is forced into the hydraulic telescopic rod 34 through the hydraulic oil pipe 39, so that clamping plate 1 32 and clamping plate 2 33 approach and squeeze the friction disc 52. At this time, the friction disc 52 is subjected to the pressure and friction of the hydraulic telescopic rod 34, clamping plate 1 32 and clamping plate 2 33, which fixes the rotated shaft 8, ensuring that the position of the fixed base 6 and the positioner will not change after the motor 7 is powered off. The middle diameter of the annular connecting block 31 is larger than the diameter of the shaft 8, and the diameter on the side near the fixed disc 51 is larger than the diameter of the extension rod 53, ensuring that the rotating mechanism 5 can rotate normally. The rotation angle of the shaft 8 and the fixed base 6 can be displayed intuitively by using the scale 38 to prevent over-rotation.

[0020] like Figure 4 and Figure 5 As shown, the protection mechanism 4 includes a connecting ring 41. Two mounting grooves are symmetrically opened on the surface of the connecting ring 41. Two springs 43 are symmetrically arranged on the inner wall of the mounting groove. A stop plate 44 is provided at the end of each spring 43 away from the inner wall of the mounting groove. Two sliding plates 42 are fixedly connected to the outer wall of the connecting ring 41. The sliding plates 42 are slidably connected inside the annular connecting block 31. The cross-sectional shape of the sliding plate 42 is L-shaped. An annular push plate 35 presses on the surface of the shorter end of the sliding plate 42. Two symmetrical limiting rods 45 are slidably connected inside the connecting ring 41. Both ends of the limiting rods 45 extend to the outside of the connecting ring 41. One end of the connecting ring 41 abuts against the surface of the annular push plate 35.

[0021] The connecting rod 54 is sleeved between the two abutment plates 44, and two limiting grooves are opened on the surface of the fixed plate 51 near the limiting rod 45. The slide plate 42 is slidably connected to the inside of the annular connecting block 31. When the clamping plate 33 approaches the friction plate 52, the annular push plate 35 also approaches the L-shaped surface of the slide plate 42, at which time the connecting ring 41 is fixed.

[0022] When the structure needs to rotate, cylinder 37 draws the hydraulic oil in the hydraulic telescopic rod 34 back into the oil tank 36, and clamping plates 32 and 33 move away from the friction disc 52. At this time, motor 7 can drive the rotating shaft 8, fixed base 6, and rotating mechanism 5 to rotate. When clamping plate 33 moves away from the friction disc 52, the annular push plate 35 also moves away from the surface of the slide plate 42. At this time, the limiting rod 45 that is in contact with the annular push plate 35 will be pushed, and the end near the rotating mechanism 5 will be inserted into the limiting groove on the surface of the fixed disc 51 and rotate together with the rotating mechanism 5. After the rotation is completed, cylinder 37 controls clamping plates 32, 33, and the annular push plate 35. The rotating mechanism 5 and the protective mechanism 4 are fixed and restricted. The limiting rod 45 will not rotate with the fixed plate 51 after leaving the limiting hole connecting ring 41. If the positioner on the fixed base 6 exceeds the maximum gravity that the locking mechanism 3 can withstand, when the motor 7 is de-energized, the rotating shaft 8 will continue to rotate under the action of gravity, overcoming the pressure and friction of the locking mechanism 3. At this time, the fixed plate 51 will continue to rotate, causing the connecting rod 54 to compress the abutment plate 44 and the spring 43. A pressure sensor is installed inside the mounting groove. When the spring 43 is compressed, the pressure sensor detects the pressure change. At this time, the gravity exceeds the maximum value, preventing accidents during use.

[0023] The working principle of this utility model is as follows: the positioner is fixed on the fixed base 6, the motor 7 drives the rotating shaft 8 to rotate and adjust the angle. The angle change can be seen intuitively through the scale 38. After the angle adjustment is completed, the locking mechanism 3 fixes the rotating shaft 8 and the fixed base 6 through the friction plate 52 to ensure that the position of the motor 7 will not change after the power is cut off. The protection mechanism 4 can detect in time the situation where the locking mechanism 3 fails to fix the rotating shaft 8 and the fixed base 6, and prevent accidents during use.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
