Description

[Technical field]

[0001] The invention belongs to the technical field of assembly line production tooling design, and in particular relates to a rapid transfer and positioning mechanism for tooling used in a production line. [Background technology]

[0002] With the reform of Industry 4.0, the manufacturing industry is gradually developing towards intelligent manufacturing. Various automation equipment and automated assembly lines are emerging one after another. To achieve fully automated production, automatic material transportation is essential. On the automatic assembly production line, tooling used to carry the components for gradual assembly is indispensable. However, the transfer efficiency of the tooling directly affects the assembly efficiency; the positioning of the tooling directly affects the assembly accuracy and the quality of the assembled product. Therefore, the rapid transfer and precise positioning of the tooling are of great significance for fully automatic assembly and fully automatic processing.

[0003] In the prior art, some tools are directly placed on the conveyor line, and when they reach the assembly station or processing station, the tooling is positioned through a blocking mechanism and a lifting and positioning mechanism; some tools are equipped with a driving gear, which cooperates with a rack track to achieve tooling transfer, and then cooperates with a blocking and positioning mechanism to achieve positioning. In the above methods, transfer and positioning are basically two separate functional modules, and the structure is relatively complex. The overall size and weight of the tooling are large, and the energy consumption is high. Blocking and lifting mechanisms are set on the assembly line, and many external auxiliary mechanisms are required to achieve tooling transfer and positioning, resulting in high production costs.

[0004] Therefore, it is necessary to provide a new rapid transfer and positioning mechanism for tooling of a production line to solve the above problems. [Summary of the invention]

A second flip plate is fixedly mounted on the flip block, and the second positioning member is fixed on the second flip plate to achieve synchronous rotation with the second rotating shaft and axial movement relative to the second rotating shaft.

[0009] Furthermore, the tooling transfer and positioning device includes a horizontal transfer block driven by the driving member to move axially along the second rotating shaft, and the horizontal transfer block is provided with an open slot facing the second rotating shaft. The flip block is inserted into or disengaged from the slot during the flipping process of the second rotating shaft, thereby realizing the opening or release of the axial drive.

[Specific implementation method]

[0027] Example:

[0028] Please refer to Figure 1-Figure 5The present embodiment provides a rapid transfer and positioning mechanism 100 for tooling for a production line, which includes a guide rail 1 for supporting and guiding the movement of the tooling, a plurality of tooling 2 moving on the guide rail 1, a tooling single-side positioning device 3 arranged on one side of the guide rail 1 and corresponding to the position of the processing workstation, and a tooling transfer and positioning device 4 arranged on the other side of the guide rail 1 and realizing the transfer and positioning of the tooling 2.

[0029] In one embodiment, a slide rail is provided on the guide rail 1, and a slider sliding on the slide rail is provided on the lower surface of the tool 2. In another embodiment, a slide rail is provided on the guide rail 1, and a roller 21 is provided on the tool 2 to clamp the slide rail from the outside and slide on the slide rail.

[0030] A circular arc groove 22 is provided on both side surfaces of the tooling 2 .

[0031] The tooling unilateral positioning device 3 comprises a first cylinder 31, a first rotating shaft 32 driven to rotate by the first cylinder 31, a first flip plate 33 fixed on the first rotating shaft 32, and a first positioning member 34 fixed on the first flip plate 33 and inserted into the arc groove 22. One end of the first cylinder 31 is hinged on a fixed seat and the other end is hinged to a swing arm 35, the swing arm 35 is fixed to one end of the first rotating shaft 32, and the first rotating shaft 32 is rotatably mounted on a fixed seat. The first cylinder 31 realizes the rotation of the swing arm 35 through the telescopic movement of the piston rod, and rotates with the first rotating shaft 32, thereby realizing the flipping of the first flip plate 33 around the axis of the first rotating shaft 32. Under the flipping of the first flip plate 33, the first positioning member 34 reciprocates in or out of the arc groove 22 to realize the positioning of the tooling 2 on one side. By designing a first flip plate 33 with a length corresponding to the distance between multiple workstations and arranging multiple first positioning members 34 on the first flip plate 33, it is possible to simultaneously achieve single-sided positioning of multiple tooling 2. Thus, one driving cylinder is used to achieve single-sided positioning of multiple tooling, which saves the number of parts, simplifies the structure, reduces costs, and better achieves synchronization.

[0032] The tooling transfer and positioning device 4 includes a driving member 41, a horizontal transfer block 42 driven by the driving member 41 to move left and right, a second rotating shaft 43 rotatable and axially movable on a fixed seat, a second cylinder 44 driving the second rotating shaft 43 to rotate, a second flip plate 45 fixed on the second rotating shaft 43, and a second positioning member 46 fixed on the second flip plate 45 and inserted into the arc groove 22. A flip block 48 is fixedly provided on the lower surface of the second flip plate 45, which is fixed to the second rotating shaft 43 by the flip block 48. An open slot 49 with one side facing the second rotating shaft 43 is provided on the horizontal transfer block 42. The flip block 48 is stuck in the slot 49. The slot 49 includes two limiting surfaces that limit the freedom of the flip block 48 in the left and right directions.

[0033] The rotating end of the driving member 41 is connected to a lead screw 412 , and the horizontal transfer block 42 is arranged on the lead screw 412 via a lead screw nut.

[0034] The outer circumferential surface of the second rotating shaft 43 is provided with an axially penetrating guide groove 47 in an annular manner, and the inner ring of the bearing supporting the second rotating shaft 43 is provided with a protrusion (not marked in the figure) that is inserted into the guide groove 47. One end of the second cylinder 44 is hinged on a fixed seat and the other end is hinged to a swing arm 410, and the other end of the swing arm 410 is sleeved on the second rotating shaft 43. One end of the second rotating shaft 43 is provided with a connecting block 411 that can move axially and rotate synchronously with respect to the second rotating shaft 43, and the connecting block 411 is fixedly connected to the swing arm 410. The connecting block 411 includes a through hole for the second rotating shaft 43 to pass through, and the inner wall surface of the through hole is provided with a protrusion that extends into the guide groove 47.

[0035] In this embodiment, the second rotating shaft 43 and the flip block 48 move axially synchronously. In another embodiment, the second rotating shaft 43 can be axially fixed, as long as the flip block 48 can achieve axial relative movement on the second rotating shaft 43, and the axial relative movement of the second rotating shaft 43 and the flip block 48 can adopt a guide rail groove structure to achieve sliding guidance and synchronous rotation drive.

[0036] Similarly, the second rotating shaft 43 and the connecting block 411 can also adopt synchronous axial movement or axial relative movement, and are arranged in coordination with the connection relationship between the second rotating shaft 43 and the flip block 48. When the second rotating shaft 43 and the flip block 48 move axially synchronously, the connecting block 411 and the second rotating shaft 43 are connected by an axial relative sliding structure, which can be specifically a guide rail and groove structure, that is, a groove or guide rail is set on the second rotating shaft 43, and a matching guide rail or groove is set on the inner wall surface of the through hole of the connecting block 411; when the second rotating shaft 43 and the flip block 48 move axially relative to each other, the connecting block 411 and the second rotating shaft 43 can adopt an axial relative sliding structure, or an axial fixed connection structure.

[0037] The first positioning member 34 and the second positioning member 46 can be a roller or a positioning column.

[0038] In this embodiment, the second rotating shaft 43 brings about the flipping of the second flip plate 45 to realize the two actions of the second positioning member 46 being inserted into the tooling 2 and detached from the tooling 2, thereby replacing the up and down movement of the positioning mechanism in the prior art. There is no need to set a large-size support plate to connect the left and right transfer drive members. During the left and right transfer drive, the left and right movement of the second positioning member 46 can be realized only through the cooperation of the card slot 49 in the horizontal transfer block 42 and the flip block 48. The guide groove 47 is provided on the second rotating shaft 43 to provide a prerequisite for the axial movement of the second positioning member 46; and the second cylinder 44, the swing arm 410 and the connecting block 411 are cooperated to realize the synchronous rotation of the second rotating shaft 43 and the swing arm 410 and the axial movement relative to the swing arm 410. The horizontal shifting of the tooling 2 can be achieved by only flipping the second rotating shaft 43 and shifting the second rotating shaft 43 to the left and right, which greatly improves the shifting speed of the tooling 2. The left and right moving distance of the second rotating shaft 43 is controlled by the servo drive in conjunction with the lead screw to ensure the movement accuracy of the tooling 2. When the tooling 2 is in place, the first positioning member 34 is inserted into the arc groove 22 on the other side of the tooling 2 by rotating the first rotating shaft 32, and the positioning is fast.

[0039] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
