The description and claims do not take the difference in name as a way of distinguishing between components, but rather take the difference in functionality of the components as a criterion for distinguishing. As used throughout the specification and claims, the word "comprise" and "comprises" are to be construed as "including, but not limited to"; by "substantially" is meant that a person skilled in the art can solve the technical problem within a certain error range, essentially achieving the technical effect.

Referring to fig. 1, an embodiment of the application provides a turning device 100, where the turning device 100 is used to implement a turning action of a workpiece 200, so as to facilitate double-sided processing of the workpiece 200 or facilitate assembly of the workpiece 200.

In this embodiment, the flipping device 100 may include a mounting base 10, a clamping mechanism 30, a rotating mechanism 50, and a telescopic supporting mechanism 70. The turning device 100 is placed or fixed on a horizontal table in a normal use state by the mounting base 10. The clamping mechanism 30 is rotatably disposed on the mounting base 10, and the clamping mechanism 30 is used for clamping the workpiece 200 to be turned over. The rotating mechanism 50 is arranged on the mounting seat 10 and is connected with the clamping mechanism 30 in a transmission way, and the rotating mechanism 50 is used for driving the clamping mechanism 30 to turn over. The telescopic support mechanism 70 includes a telescopic frame 72 and a support frame 74, and the support frame 74 is connected to the telescopic frame 72 and located at one side of the clamping mechanism 30. The telescopic frame 72 is used for driving the supporting frame 74 to be close to the clamping mechanism 30 so as to support the workpiece 200, and the telescopic frame 72 is used for driving the supporting frame 74 to be far away from the clamping mechanism 30 so as to give way to the workpiece 200 when the clamping mechanism 30 is overturned.

When the turning device 100 is used, a worker may place the workpiece 200 to be turned over on the clamping mechanism 30 using a traveling crane, and clamp the workpiece 200 using the clamping mechanism 30. The support frame 74 of the telescopic support mechanism 70 abuts against the bottom of the workpiece 200 to support the workpiece 200, and at this time, the first surface of the workpiece 200 can be machined and assembled. When the workpiece 200 needs to be turned over, the telescopic frame 72 drives the support frame 74 to move away from the workpiece 200 (namely away from the clamping mechanism 30), until the distance between the support frame 74 and the workpiece 200 is enough for the workpiece 200 to be turned over, the rotating mechanism 50 is started, and the clamping mechanism 30 is controlled to be turned over, so that the workpiece 200 is driven to be turned over. After the workpiece 200 is turned in place, the telescopic frame 72 drives the supporting frame 74 to move close to the workpiece 200 (i.e. close to the clamping mechanism 30) until the supporting frame 74 is abutted against the workpiece 200 again to support the workpiece 200, and at this time, the second face of the workpiece 200 can be machined and assembled. After completion, the clamping mechanism 30 releases the constraint on the work piece 200 and the worker can transport the completed work piece 200 to the finished product storage location again by the traveling crane.

In some embodiments, the support frame 74 may be detachably connected to the expansion bracket 72, in which embodiment the mounting base 10 may be provided with a relief space 11, the support frame 74 traversing the relief space 11 to support the bottom of the workpiece 200, when the workpiece 74 needs to be turned, the support frame 74 only needs to be moved slightly away from the workpiece 200, and then the support frame 74 is detached to be disengaged from the relief space 11, so that the workpiece 200 may be turned by means of the empty space of the relief space 11, and thus the support frame 74 for supporting the workpiece 200 does not affect the turning of the workpiece 200, while saving the stroke of the expansion bracket 72 and reducing the overall volume of the turning device 100. When support is required, the support frame 74 is mounted to the telescopic frame 72, and then the telescopic frame 72 drives the support frame 74 to move close to the workpiece 200 (i.e., close to the clamping mechanism 30) until the support frame 74 is again abutted against the workpiece 200 to support the workpiece 200.

The workpiece 200 is clamped and the turnover motion is carried out on the turnover device 100, the telescopic supporting mechanism 70 can support the workpiece 200, the turnover of the workpiece 200 is not hindered, a worker does not need to utilize the wood Fang Diangao workpiece for multiple times to realize turnover, and the processing and assembling efficiency of the workpiece 200 is improved. Meanwhile, an operator can turn over the track away from the workpiece 200, so that the operation safety is improved.

The number of the buffers 34 is four, and the four buffers 34 are arranged substantially uniformly in the circumferential direction of the clip 32.

The specific type of the telescopic driving unit 721 is not limited in this specification, and for example, the telescopic driving unit 721 may be a cylinder, an electric cylinder, a linear motor, a lifter, or the like. In the present embodiment, the telescopic driving element 721 is a lifter.

When the workpiece 200 needs to be turned over, a worker can start the telescopic driving element 721 to enable the mounting frame 723 to descend, the mounting frame 723 drives the supporting frame 74 to move away from the workpiece 200 until the distance between the supporting frame 74 and the workpiece 200 is enough for the workpiece 200 to be turned over, and the rotating mechanism 50 is started to control the clamping mechanism 30 to be turned over, so that the workpiece 200 is driven to be turned over.

Referring to fig. 2 and 4, in some embodiments, the support frame 74 may be detachably connected between the two horizontal portions 7234, in which embodiment the support frame 74 only needs to be slightly moved away from the workpiece 200, and then the support frame 74 is detached to also not affect the turning of the workpiece 200, while saving the stroke of the telescopic driving member 721 and reducing the overall volume of the turning device 100. Specifically, the horizontal portion 7234 is provided with mounting notches 7236, and the two mounting notches 7236 of the two horizontal portions 7234 are arranged at intervals along the axial direction B of the first rotating shaft 54. Two ends of the supporting frame 74 are respectively embedded into two mounting notches 7236. The support frame 74 can be quickly and conveniently assembled and disassembled with the mounting frame 723 through the mounting notch 7236. The specific structure of the support 74 is not limited in this specification, and for example, the support 74 may be plate-shaped, column-shaped, or tubular. In this embodiment, the support 74 is a square tube. The number of the supporting frames 74 may be two, and the two supporting frames 74 are connected between the two horizontal portions 7234 and are arranged at intervals in parallel in the extending direction of the horizontal portions 7234. The two support brackets 74 enhance the support of the workpiece 200.

When the workpiece 200 needs to be turned over, a worker may activate the telescopic drive 721 to lower the mounting bracket 723, the mounting bracket 723 drives the support brackets 74 to move away from the workpiece 200, and then the two support brackets 74 are pulled out from the mounting notches 7236. The rotating mechanism 50 is started to control the clamping mechanism 30 to turn over, so that the workpiece 200 is driven to turn over. After the workpiece 200 is turned over, a worker installs the two support frames 74 under the workpiece 200 from the installation notch 7236, and starts the telescopic driving element 721 again to enable the installation frame 723 to ascend, and the installation frame 723 drives the support frames 74 to move close to the workpiece 200 until the support frames 74 are abutted against the workpiece 200, so that a supporting effect is achieved.

It should be understood that "an element abuts against another element" in this specification, it should be understood that the two may abut directly or indirectly (e.g., when there is an intervening element therebetween), e.g., the other element is mounted on the intervening element, and the element may abut against the intervening element, thereby "abutting against the other element". In this embodiment, the turning device 100 may further include a protection pad 80, where the protection pad 80 is disposed on a side of the support frame 74 facing the clamping mechanism 30. When the supporting frame 74 plays a supporting role, the supporting frame 74 indirectly abuts against the workpiece 200 through the protection pad 80. The protection pad 80 is used to protect the workpiece 200, reducing the possibility of damage to the painted surface of the workpiece 200. The specific material of the protection pad 80 is not limited in this specification, and for example, the protection pad 80 may be made of nylon, rubber, sponge, etc., and in this embodiment, the protection pad 80 is made of nylon plate.

In this embodiment, the telescopic support mechanism 70 may further include a fixing base 76 and a guiding telescopic rod 78, the telescopic driving element 721 is installed on the fixing base 76, the fixing base 76 and the mounting frame 723 are relatively spaced, and two ends of the guiding telescopic rod 78 are respectively connected to the fixing base 76 and the mounting frame 723. The fixing base 76 may be fixedly installed on a table surface on which the tilting device 100 is placed in a normal use state, and the fixing base 76 is used for improving the stability of installation of the telescopic driving element 721. The fixing base 76 is disposed at a distance from the horizontal portion 7234, and has a substantially rectangular plate shape. The horizontal portions 7234 of the holders 76 are arranged in one-to-one correspondence. Two telescopic drives 721 on the same side of the clamping mechanism 30 are fixedly connected to a fixed base 76.

A guide telescopic rod 78 is connected between the fixing base 76 and its corresponding horizontal portion 7234, the guide telescopic rod 78 serving to provide a guide for the movement of the mounting bracket 723. As an example, the guide telescoping rod 78 may include a rod sleeve 781 and a rod 783, the rod 783 slidably disposed within the rod sleeve 781, either one of the rod 783 and the rod sleeve 781 being connected to the horizontal portion 7234 and the other being connected to the anchor block 76. When the support bracket 74 is abutted against the workpiece 200, the rod body 783 still has at least a part of structure located in the rod sleeve 781. The number of the guiding telescopic rods 78 is also two, and the two guiding telescopic rods 78 are respectively positioned at two sides of the clamping mechanism 30 and are arranged in one-to-one correspondence with the two fixing seats 76. The two guide telescoping rods 78 further enhance the stability of telescoping the telescoping support mechanism 70.

When the turnover device 100 provided by the embodiment of the application is used, a worker can place the workpiece 200 to be turned into the clamping channel 321 of the clamping piece 32 by adopting the crane equipment, and the clamping piece 32 holds the workpiece 200 tightly. The worker activates the telescopic drive 721 to lower the mounting bracket 723, the mounting bracket 723 drives the support brackets 74 to move away from the workpiece 200, and then the two support brackets 74 are withdrawn from the mounting notches 7236 to give way to the rotation of the workpiece 200. The worker manually rotates the hand wheel 521, and the hand wheel 521 drives the first rotation shaft 54 and the clamping member 32 to rotate through the speed reducer 523. After the workpiece 200 is turned in place, a worker installs the two support frames 74 under the workpiece 200 from the installation notch 7236, and starts the telescopic driving element 721 again to enable the installation frame 723 to ascend, and the installation frame 723 drives the support frames 74 to move close to the workpiece 200 until the support frames 74 are abutted against the workpiece 200, so that a supporting effect is achieved, and at the moment, the second face of the workpiece 200 can be machined and assembled. After completion, the clamping mechanism 30 releases the constraint on the work piece 200 and the worker can transport the completed work piece 200 to the finished product storage location again by the traveling crane.
