Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and in particular relates to a turning device suitable for large-aperture optical lenses. Background Art

[0002] Flipping devices are common operating equipment in industrial production, used to change the position or orientation of a workpiece during the production process. Especially when processing the surface of an object, the object must be flipped before processing can proceed. Taking large-aperture optical lenses as an example, existing flipping devices for large-aperture optical lenses include a support frame and hanging plates mounted on either side of the frame. The large-aperture optical lens is mounted in a fixture equipped with a pair of workpiece lifting shafts. These shafts must be inserted into the two hanging plates to lift and flip the workpiece. Before the workpiece lifting shafts can be inserted into the two hanging shafts, one hanging plate must be removed. The two hanging plates can then be inserted into the workpiece lifting shafts. The removed hanging plates must then be installed. Only after installation is complete can the workpiece be lifted and flipped. The entire flipping process is cumbersome, time-consuming, and inefficient. Because both the support frame and hanging plates are made of metal, the lifting weight is heavy. With the rapid development of industrial automation and intelligentization, the requirements for flipping speed, stability, and ease of operation of flipping devices such as large-aperture optical lenses are becoming increasingly stringent. Summary of the Invention

[0003] In order to overcome the defects of low efficiency and large lifting weight of the existing turning device, the utility model provides a turning device suitable for large-aperture optical lenses. By improving the existing turning device, a detachable lifting shaft is used in combination with a lifting belt to achieve rapid lifting.

[0004] The technical solution adopted by the utility model is: a flip device suitable for large-diameter optical lenses, comprising: a support mechanism and a suspension mechanism for cooperating with the flipping,

The support plates are symmetrically arranged. The support blocks are fixed between the two support plates and spaced apart along the length of the support plates. The reinforcing ribs 7 are fixed to the bottoms of the two symmetrically arranged support blocks. The lifting shafts are symmetrically and detachably arranged on the support plates.

[0006] The suspension mechanism for cooperating with the flipping is used to suspend the workpiece and cooperate with the flipping, and includes: a sling, one end of which is a free end for connecting with the workpiece; an end of the sling away from the free end is sleeved on the lifting shaft to connect the sling with the support plate;

[0007] At least one pair of lower side guard plates are provided on the outer side of the reinforcing ribs along the layout direction of the sling, and an accommodating cavity for restricting the left and right displacement of the sling is provided in the lower side guard plates.

[0008] Preferably, there are at least three support blocks arranged at intervals, and the support block located at the center of the support plate is the central support block, and the support blocks located at both ends of the support plate are end support blocks.

[0015] The beneficial effects of the utility model are:

[0016] 1. The utility model adopts a portal support mechanism and a sling, which effectively improves the bearing capacity and stability of the overall structure of the device without increasing the lifting weight too much. The application of the sling effectively solves the cumbersome current situation of the flipping operation of the existing large-aperture optical lens after lifting. The upper part of the sling is constrained by setting a side guard plate to avoid the sling from slipping when the workpiece is lifted or flipped. At the same time, it also reduces the amplitude of the swing of the workpiece during the movement, providing a guarantee for the smooth flipping of the workpiece.

[0022] like Figure 1 and Figure 2 As shown, the present invention is a flipping device suitable for large-diameter optical lenses. The flipping device is used in conjunction with a crane. This application only optimizes the structure of the flipping device. The flipping device includes a support mechanism and a suspension mechanism for flipping. The support mechanism is used to enhance the overall rigidity and stability of the structure. The suspension mechanism for flipping is used to suspend and flip a workpiece 10. The workpiece 10 refers to a fixture that carries a large-diameter optical lens. A pair of workpiece lifting shafts 9 are provided on the fixture. The shafts are connected to the suspension mechanism for flipping to achieve the lifting and flipping of the workpiece 10.

[0023] The support mechanism includes: a support plate 1, a support block 2, a lifting shaft 3 and a reinforcing rib 7. The support plate 1 is a plate-like structure, symmetrically arranged on both sides of the support blocks 2 arranged at intervals of "one line", and the support plate 1 and the support block 2 are fixedly connected by bolts 4. The support blocks 2 are an odd number of more than three. This embodiment is introduced by taking three support blocks 2 as an example, wherein: one support block 2 is located in the middle of the support plate 1, which is the center support block; the remaining support blocks 2 are located at both ends of the support block 2, which are end support blocks. There are two lifting shafts 3, which are symmetrically and detachably arranged on the support plate 1 and are located between the center support block and the end support block. Specifically, one end of each lifting shaft 3 is passed through and fixed to the support plate 1 by a nut. There are two symmetrically arranged reinforcing ribs 7, which are vertically fixed to the bottom of the two end support blocks 2 by bolts 4.

[0024] The suspension mechanism for cooperating with the flipping includes: a sling 5 and a side guard plate. The sling 5 is provided with a free end for establishing a connection with the workpiece 10. Specifically, a mounting hole is provided near the free end of the sling 5, and the mounting hole is used in conjunction with the workpiece lifting shaft 9 of the workpiece 10. The side of the sling 5 away from the free end is used to establish a connection with the support mechanism. Specifically, a positioning hole is provided on the side of the sling 5 away from the free end. The lifting shaft 3 passes through the positioning hole to establish a connection between the sling 5 and the support plate 1. The slings 5 ​​in this embodiment can be selected from two slings 5 ​​of equal length, or a longer sling 5 can be selected. When hoisting objects, whether one or two slings 5 ​​are selected, the connection method, role played and effect achieved in the flipping device are the same, but more possibilities are provided in terms of use.

[0025] Furthermore, in order to keep the lifted workpiece 10 in a relatively stable state during the movement and flipping process, to prevent the sling 5 from detaching from the reinforcing rib 7, and to reduce the swinging of the sling 5 during the movement and flipping, at least one pair of side guards are provided on the outside of each end support block and / or reinforcing rib 7. The side guards are welded to the outer side walls of the end support block and / or reinforcing rib 7. A receiving cavity for accommodating the sling 5 is formed between the side guards and the end support block and / or reinforcing rib 7, and the left and right displacement of the sling 5 is constrained by the receiving cavity. Specifically, the free end of the sling 5 passes through the side guard and establishes a connection with the workpiece 10. During the movement or flipping of the workpiece 10, the upper part of the sling 5 is always constrained in the side guard. Preferably, the side guards in this embodiment are two groups, namely, an upper side guard 6 and a lower side guard 8 arranged at intervals in the longitudinal direction. The upper side guard 6 is welded to the end support block, and the lower side guard 8 is welded to the reinforcing rib 7.

[0026] The two arms of the lifting hook are detachably fixed to the support plate 1 via the lifting shaft 3. When lifted by the crane, the arms form an inverted V shape. The lifting hook can be made of different materials, such as an integrally formed metal hook or a split articulated metal hook. The lifting hook can also be made of the same material as the lifting strap 5. The specific material selection and connection method are optional.

[0027] Working process:

[0028] like Figure 3 As shown, before lifting and flipping: First, separate the lifting shaft 3 from the support plate 1, insert the lifting belt 5 into the lifting shaft 3, and secure the lifting shaft 3 to the support plate 1 with nuts. Then, pass the free end of the lifting belt 5 through the upper side guard plate 6 and the lower side guard plate 8 in sequence to prevent the lifting belt 5 from sliding left or right during lifting or flipping. Finally, insert the two ends of the workpiece lifting shaft 9 into the mounting holes at the free ends of the upper lifting belt 5.

[0029] When lifting and flipping: After the workpiece 10 is lifted to an appropriate height and position, the workpiece 10 is flipped by manually pushing it within the range enclosed by the two slings 5 ​​and the support plate 1, and the slings 5 ​​will not interfere with the flipping of the lens.

[0030] After the flip is completed: after the flip is completed, the workpiece 10 is dropped and the sling 5 and the workpiece lifting shaft 9 can be separated.

The scope of protection of the present invention is not limited to these embodiments. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
