Description

Technical Field

[0001] The utility model relates to the field of pressure beam lifting, in particular to a lifting device and an edge grinding machine. Background Art

[0002] At present, in addition to using a beam belt to transport and support the workpiece, the pressure beam device is also used to press and transport the upper surface of the workpiece, so that the workpiece will not shake left and right during the processing to ensure the processing size accuracy. The pressure beam device uses a rotating arm device as support and drive.

[0003] like Figure 1 As shown, the support plate of the swivel arm device 1' is installed on the crossbeam 3', one end of the swivel arm is installed on the support plate as the rotation center, and the other end is connected to the cylinder and the pressure beam 2' respectively, and is driven to rise and fall by the cylinder, thereby driving the pressure beam to rise and fall. However, due to structural limitations, the stroke of the swivel arm device is limited, so it is required that the workpiece 10' in the longitudinal direction, that is, the thickness, cannot exceed the stroke of the swivel arm device (≤30mm). If the size is adjusted on the existing structure to increase the lifting stroke of the pressure beam, on the one hand, it will cause the size of each part to be increased to meet the requirements of the swivel arm rotation angle, and on the other hand, if the swivel arm rotation angle is too large, it may cause the swivel arm and the swivel arm fixed axis to be poorly stressed when the pressure beam presses the workpiece, and it is not durable.

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0029] See also Figure 2-5 , the utility model discloses a lifting device, including a rotating arm mechanism 1 and a lifting mechanism for lifting the rotating arm mechanism 1;

[0030] The lifting mechanism comprises a support frame 2 and a lifting power mechanism and a transmission assembly mounted on the support frame 2, wherein the lifting power mechanism is connected to the transmission assembly, and the transmission assembly is connected to the rotating arm mechanism 1;

[0031] The lifting power mechanism drives the transmission assembly to drive the rotating arm mechanism 1 to lift.

[0032] The lifting device of the utility model is based on the original arm mechanism, and the lifting mechanism is added. Through the cooperation of the lifting power mechanism and the transmission assembly, the longitudinal stroke of the arm mechanism can be increased, thereby expanding the processing range and making the thickness range of the workpiece that can be processed larger. The original arm mechanism structure remains unchanged, ensuring that the force condition remains unchanged when the pressure beam presses the workpiece, and also ensuring its durability.

[0033] The swing arm mechanism 1 comprises a support plate 13, a swing arm 11 and a swing arm power mechanism 12 mounted on the support plate 13, wherein the swing arm 11 is connected to the swing arm power mechanism 12. The swing arm power mechanism 12 is a cylinder. A pressure beam shaft is provided on the swing arm, and the swing arm is connected to the pressure beam through the pressure beam shaft.

[0034] Specifically, one end of the rotating arm 11 is a supporting end 111, and the other end is a lifting end 112. The supporting end 111 is movably connected to the support plate 13, and the lifting end 112 is movably connected to the rotating arm power mechanism 12. Preferably, the supporting end 111 is hinged to the support plate 13, and the lifting end 112 is movably connected to the rotating arm power mechanism 12 through a connecting assembly. The pressure beam shaft is arranged on the lifting end. Driven by the rotating arm power mechanism, the lifting end rotates around the hinge shaft of the supporting end and the support plate, and lifts and lowers, driving the pressure beam on the pressure beam shaft to rise and fall. At the same time, the pressure beam shaft is used to transmit power, so that the pressure beam presses the workpiece on the crossbeam. The rotating arm power mechanism uses the rotating arm to transmit power to the pressure beam, which not only ensures the effective connection with the pressure beam, but also can use the rotating arm to drive the pressure beam to rise and fall, and can ensure that the pressure is transmitted to the pressure beam through the lifting end, and then the pressure beam presses the workpiece on the crossbeam. Its structure is simple, space-saving, and effective pressure is applied.

[0035] like Figure 4 As shown, the connection assembly includes a slider 141 and a slider seat 142, the slider 141 and the slider seat 142 are slidably connected, the slider 141 is connected to the swing arm power mechanism 12, and the slider seat 142 is arranged on the lifting end 112. The setting of the connection assembly facilitates the connection between the output end of the swing arm power mechanism and the lifting end of the swing arm, and converts the longitudinal movement of the swing arm power mechanism output end into an arc line movement of the lifting end rotating around the support end, effectively transmits power, and realizes the lifting and lowering of the lifting end, i.e., the pressure beam. It has a simple structure and reliable power transmission.

Specifically, the screw nut 8 is installed on the support plate 13. The lifting power mechanism drives the screw rod to rotate, so that the screw nut moves back and forth along the screw rod, thereby driving the swivel mechanism to rise and fall. Compared with the existing swivel mechanism directly fixed on the crossbeam, the utility model lifts the swivel mechanism through the lifting mechanism, so that the swivel mechanism as a whole increases the distance from the crossbeam, increases the distance between the swivel arm and the crossbeam, and increases the stroke of the swivel arm in the longitudinal direction, so that a thicker workpiece can be placed between the pressure beam and the crossbeam, thereby ensuring that the processing range is expanded under the original force conditions.

Specifically, the reducer 3 is connected to the support plate 13 of the first tumbler mechanism 1a through a transmission assembly. The reducer drives the first tumbler mechanism to rise and fall using the transmission assembly.

Among them, the reducer is connected to the second support frame through another group of transmission assemblies to drive the second tumbler mechanism to rise and fall as a whole. The reducer and the reducer are connected through the connecting assembly to realize power transmission, so as to ensure that the first tumbler mechanism and the second tumbler mechanism can be raised and lowered synchronously, thereby ensuring that the pressure beam as a whole can be raised and lowered synchronously.

[0042] Among them, Figure 5 As shown, the connecting assembly 5 includes a coupling 51 and a connecting shaft 52, the reducer 3 is connected to the connecting shaft 52 through the coupling 51, and the reducer 4 is connected to the connecting shaft 52 through the coupling 51, so as to realize synchronous lifting and lowering of the first rotating arm mechanism and the second rotating arm mechanism.

[0043] Preferably, if Figure 5As shown, the utility model further comprises an encoder 6 mounted on the first support frame 2a, and the encoder 6 is connected to the reducer 3. The encoder can be used to monitor the operation of the reducer, so as to control the movement stroke of the rotating arm mechanism.

Specifically, the first support frame 2a and the second support frame 2b are respectively fixedly connected to the crossbeam, and the pressure beam 9 is respectively connected to the first swivel mechanism 1a and the second swivel mechanism 1b. The specific structure of the lifting device is as described above and will not be repeated here.
