Description

Technical Field

[0002] For some materials, during the processing operation, it is often required that the materials are in a suitable position and angle. Therefore, from the loading process, a positioning mechanism is needed to pre-position the materials. However, when the materials are being processed, the positioning mechanism needs to release the limit to prevent interference with the processing operation of the materials. After the materials are processed, they will be removed by unloading, and new materials need to be loaded again. The positioning mechanism needs to re-pre-position the new materials. Running repeatedly in this way, the operation is cumbersome, the processing efficiency is not high enough, and it is not conducive to the smooth flow of materials between various processes.

It only needs to slide the sliding block in one direction on the rotating bracket, which is simple to operate, which is convenient for the workpiece to be processed at the working station, and can quickly create positioning conditions for the new workpiece at the loading station, thereby realizing cyclic rapid loading, ensuring the smooth flow of workpieces between each process, and improving processing efficiency.

The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0026] In the description of the present utility model, unless otherwise clearly defined, terms such as "arrangement", "installation", and "connection" shall be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0027] Referring to Figures 1 to 7 , the present utility model discloses a circulating feeding and positioning device, which includes a frame 1, a rotating bracket 2, a rotating mechanism 3, two supporting platforms 4, and a sliding block 6.

[0028] Referring to Figure 2 , the rotating bracket 2 is installed on the frame 1 through the rotating mechanism 3, and the rotating bracket 2 can horizontally rotate 180° relative to the frame 1.

[0029] Among them, the frame 1 has a feeding station 11 and an operating station 12. The two supporting platforms 4 are arranged on the rotating bracket 2 at intervals in the front-rear direction and are respectively located at the feeding station 11 and the operating station 12. Each supporting platform 4 can rotate and switch between the feeding station 11 and the operating station 12. The supporting platform 4 located at the feeding station 11 is configured to place the workpiece 5, and the supporting platform 4 located at the operating station 12 is configured to support the workpiece 5 for operation.

[0030] It can be understood that the device adopts the method of circulating and rotating the supporting platform 4, and the two supporting platforms 4 on the rotating bracket 2 respectively rotate and switch in a cycle between the feeding station 11 and the operating station 12.

[0031] Referring to Figure 1 , Figure 6 and Figure 7 , the workpiece 5 has a limited portion 51. Two limiting portions 61 are respectively arranged at the front and rear ends of the sliding block 6, and the two limiting portions 61 respectively face the two supporting platforms 4 and are used to limit and constrain the limited portion 51 of the workpiece 5.

[0032] Referring to Figures 4 to 6 , the sliding block 6 is slidably connected to the rotating bracket 2 and can move between the two supporting platforms 4, so that one of the limiting portions 61 approaches the feeding station 11 to cooperate with the corresponding supporting platform 4 to position and place the workpiece 5, and at the same time, the other limiting portion 61 moves away from the operating station 12 to release the constraint on the workpiece 5 supported on the corresponding supporting platform 4.

[0033] Since the limiting portion 61 of the sliding block 6 can limit and constrain the limited portion 51 of the workpiece 5, the sliding block 6 is moved between the two supporting platforms 4 to make one of the limiting portions 61 close to the loading station 11 to cooperate with the corresponding supporting platform 4 to position and place the workpiece 5, and at the same time, the other limiting portion 61 will be moved away from the working station 12 to release the constraint on the workpiece 5 supported on the corresponding supporting platform 4. It is only necessary to slide the sliding block 6 in one direction on the rotating bracket 2. The operation is simple, which not only facilitates the processing of the workpiece 5 at the working station 12, but also can quickly create positioning conditions for the new workpiece 5 at the loading station 11, thereby realizing cyclic rapid loading, ensuring the smooth flow of the workpiece 5 between the various processes, and improving the processing efficiency.

[0034] In some embodiments of the present invention, referring to Figure 1 , Figure 5 and Figure 6 The bottom of the workpiece 5 has a cylindrical groove 52, and the supporting platform 4 is provided with a cylindrical boss 41, and the cylindrical boss 41 is inserted into the cylindrical groove 52. When the limiting portion 61 releases the constrained portion 51 of the workpiece 5, the workpiece 5 can rotate freely relative to the cylindrical boss 41. Therefore, the limiting portion 61 cooperates with the supporting platform 4 to support and limit the workpiece 5.

[0035] The limited portion 51 may be a lug, and the limited portion 61 may be a positioning notch.

[0036] In some embodiments, reference Figure 4 A guide rail 21 and a linear drive mechanism 22 are installed on the rotating bracket 2. The guide rail 21 extends in the front-to-back direction. The sliding block 6 is slidably installed on the guide rail 21. The linear drive mechanism 22 is transmission-connected to the sliding block 6. The linear drive mechanism 22 can drive the sliding block 6 to slide on the guide rail 21.

[0037] The linear drive mechanism 22 may specifically be a linear cylinder.

[0038] Reference Figure 4 and Figure 5 In some embodiments, a first stopped portion 62 is provided on the sliding block 6, and the rotating bracket 2 is provided with a first stopper 23 in front of and behind the first stopped portion 62. Both sets of first stoppers 23 can cooperate to block the first stopped portion 62 to limit the moving range of the sliding block 6, thereby assisting the linear drive mechanism 22 and ensuring the accuracy of the extreme position of the sliding block 6.

[0039] Reference Figure 2 The rotating mechanism 3 can be specifically a rotating cylinder, wherein the cylinder body of the rotating mechanism 3 is fixedly mounted on the frame 1, and the rotating bracket 2 is mounted on the rotating output end of the rotating mechanism 3. By controlling the rotation angle of the rotating mechanism 3, the rotating bracket 2 can be horizontally reciprocated by 180° relative to the frame 1.

[0040] Referring to Figure 3 , in some embodiments, the rotating bracket 2 is extended with a second stopper portion 24, and the machine frame 1 is provided with second stoppers 13 at both ends of the rotation path of the second stopper portion 24. Both groups of second stoppers 13 can cooperate to block the second stopper portion 24, so as to assist the rotating mechanism 3 and ensure the position accuracy of the rotating bracket 2 at the loading station 11 and the working station 12.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0042] Certainly, the present utility model is not limited to the above embodiments. Those skilled in the art can also make equivalent deformations or substitutions without departing from the spirit of the present utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
