Description

Technical Field

[0001] The utility model relates to the field of tooling, and more specifically, to a bracket flipping and lifting mechanism. Background Art

[0002] Many devices have the need to switch between workstations. For production devices under a single workstation, there is also the need to switch between the working position and the maintenance position. In addition to displacement, many existing workstation switching structures are often accompanied by posture rotation during the switching process, which makes the device susceptible to the impact of switching and is not conducive to maintaining the accuracy of high-precision devices.

[0003] There is an urgent need for a bracket flipping and lifting mechanism as a workstation switching mechanism to improve the stability of the mechanism during the workstation switching process, eliminate rotation, and avoid the impact of the mechanism caused by the switching displacement. Summary of the invention

[0004] The utility model provides a bracket flip lifting mechanism, which can ensure that the posture of the mechanism remains unchanged during the lifting process, thereby improving the stability of the mechanism during the movement process.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A bracket flipping and lifting mechanism is used to lift a lifting device, including a connecting rod mechanism, a fixed support and a telescopic driver. The lifting device is fixedly connected to the connecting bracket. The connecting rod mechanism includes two parallel connecting rods, one end of the two connecting rods is respectively hingedly connected to the connecting bracket, and the other end is respectively hingedly connected to the fixed support. The fixed end of the telescopic driver is arranged below the connecting rod mechanism and is rotatably connected to the fixed support. The telescopic end of the telescopic driver is hingedly connected to a connecting rod of the connecting rod mechanism. Through the drive of the telescopic driver, the connecting rod mechanism is pushed to drive the connecting bracket to rotate around the fixed support.

[0007] As the main force-bearing member, the four-link structure is subjected to the thrust from the telescopic drive and the pressure generated by the gravity of the connecting bracket and the lifting device. Through the hinge between it and the fixed support, the connecting bracket and the lifting device are rotated relative to the fixed support, thereby achieving the lifting purpose. On this basis, the two ends of the connecting rod are respectively hingedly connected to the connecting bracket and the fixed support. Since the positions of the hinge points on the connecting bracket and the fixed support remain unchanged, and the length of the connecting rod is not diagonal, a parallelogram is formed, so that the relative connecting rods are always parallel. Therefore, the sides of this quadrilateral between the hinge points on the connecting bracket and the fixed support are always parallel. In this way, during the movement, the posture of the connecting bracket and the lifting device thereon is always unchanged, which improves the stability of the mechanism during movement and reduces the impact on the mechanism during movement.

[0008] Preferably, an upper limit block and a lower limit block are provided on the fixed support, and when the quadrilateral mechanism is lifted or lowered to fit with the upper limit block or the lower limit block, the lifting device reaches a high position or a low position.

[0009] Preferably, a locking mechanism is also included, which includes a locking driver, the movement direction of the telescopic end of the locking driver is perpendicular to the movement direction of the connecting rod mechanism, the positioning adjustment block is arranged on the connecting rod, the positioning adjustment block is provided with a pin hole, and the telescopic end of the locking driver is inserted into the pin hole to lock the connecting rod mechanism.

[0010] Preferably, the positioning adjustment block is detachably connected to a connecting rod, and the connecting rod is provided with a plurality of positions for connecting the positioning adjustment block.

[0011] Preferably, a high position in-place sensor and a low position in-place sensor are provided on the fixed support.

[0012] Preferably, a contact block for abutting against the upper limit block or the lower limit block is provided on the connecting rod, and a side of the contact block away from the connecting rod is a convex curved surface.

[0013] Preferably, the telescopic drive is a cylinder.

[0014] Preferably, the locking actuator is a pneumatic cylinder.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) A parallelogram-shaped connecting rod is used to ensure that the posture of the connecting bracket and the lifting device on it remains unchanged during the lifting process, thereby improving the stability of the mechanism during movement and reducing the impact on the mechanism during movement;

[0017] (2) Use the locking mechanism to lock the connecting rod in the high position to ensure the stability of the lifting device. BRIEF DESCRIPTION OF THE DRAWINGS

Through the hinge between it and the fixed support 2, the connecting bracket 12 and the lifting device 1 are rotated relative to the fixed support 2, thereby achieving the lifting purpose. On this basis, the two ends of the connecting rod 4 are respectively hingedly connected to the connecting bracket 12 and the fixed support 2. Since the positions of the hinge points on the connecting bracket 12 and the fixed support 2 remain unchanged, and the length of the connecting rod 4 is not scalable, a parallelogram is formed. Therefore, the sides of this quadrilateral between the hinge points on the connecting bracket 12 and the fixed support 2 are always parallel. In this way, during the movement, the posture of the connecting bracket 12 and the lifting device 1 thereon is always unchanged, which improves the stability of the mechanism during movement and reduces the impact on the mechanism during movement.

The telescopic end of the telescopic drive 3 is hingedly connected to the connecting rod 4 by passing a connecting pin through the connector and the hinged joint.

[0035] An upper limit block 5 and a lower limit block 6 are provided on the fixed support 2. When the quadrilateral mechanism is lifted and lowered to fit with the upper limit block 5 or the lower limit block 6, the lifting device 1 reaches the high position 7 or the low position 8. A contact block 11 for fitting with the upper limit block 5 or the lower limit block 6 is provided on the connecting rod 4. The side of the contact block 11 away from the connecting rod 4 is a convex curved surface. The high position 7 and the low position 8 correspond to the working position and the maintenance position of the lifting device 1, respectively.

[0037] Ginseng Figure 3, and also includes a locking mechanism, the locking mechanism includes a locking driver 9, the movement direction of the telescopic end of the locking driver 9 is perpendicular to the movement direction of the connecting rod mechanism, the positioning adjustment block 10 is arranged on the connecting rod 4, and the positioning adjustment block 10 is provided with a latch hole, and the telescopic end of the locking driver 9 is inserted into the latch hole to lock the connecting rod mechanism. In some embodiments, the positioning adjustment block 10 is detachably connected to the connecting rod 4, and the connecting rod 4 is provided with several positions for connecting the positioning adjustment block 10, so that the specific high position 7 can be adjusted. Among them, the telescopic end of the locking driver 9 includes the telescopic end itself or the latch fixedly connected thereto, and this application is not limited to this.
