Description

Technical Field

[0001] This utility model relates to the field of circulating feeding technology, and in particular to a station tooling component and a multi-station circulating hopper with station tooling component. Background Technology

[0002] Tooling components are key parts that support, position, and fix workpieces for production and processing. In order to achieve continuous production, tooling needs to be efficiently and accurately transferred between various processing, inspection, and assembly stations.

[0003] Therefore, the tooling conveying solutions commonly used in workshops often adopt a "dedicated machine for dedicated use" model, that is, custom-developed conveying equipment (one-to-one matching) for tooling with different structures, sizes, and specifications. This solution is applicable to production lines with a single type of tooling, but with the increasing demand for diversified products and production processes, the types and structures of tooling components used in workshops are becoming more varied, leading to the following drawbacks: 1) Low space utilization: Each new type of tooling requires a separate conveyor line or a dedicated piece of equipment. These single-function devices occupy a significant amount of floor and overhead space in the workshop, resulting in a waste of workshop area; 2) High equipment costs: Repeated design, manufacturing and procurement of non-standard equipment leads to a sharp increase in both initial investment and subsequent maintenance costs; 3) The system has extremely poor flexibility: once the product is changed, the original special conveying equipment is often unable to adapt to the new tooling and will face obsolescence or require a lot of cost to modify.

[0004] In summary, this utility model designs a workstation tooling component and a multi-station circulating hopper with workstation tooling component that can overcome the above-mentioned defects of the prior art. Utility Model Content

The other side of the workpiece positioning head is provided with a positioning protrusion two. As a further improvement, the tooling plate and the workpiece positioning head are detachably fixed, and the tooling plate has support arms extending outward on both sides, which are used to cooperate with the lifting mechanism of the end of the conveying equipment.

[0007] As a further improvement, the positioning tray and tooling plate are detachable and fixed, and the positioning tray is also equipped with symmetrically arranged positioning posts.

[0008] As a further improvement, a positioning groove is provided on the contact surface between the tooling plate and the workpiece positioning head, which mates with the positioning protrusion on the workpiece positioning head.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 A workstation tooling component is provided to address the diverse types and structures of tooling components. One workstation tooling component can be used for multiple workstation toolings, requiring only one conveyor device to match, thus saving production workshop space.

[0019] The components, arranged from top to bottom, are: workstation fixture 10, workpiece positioning head 20, fixture plate 30, and fixture positioning tray 40. The workpiece positioning head 20 has a positioning protrusion 21 on its contact surface with the station fixture 10. The positioning protrusion 21 matches the structure of the station fixture 10 and is used for the placement of the station fixture 10. The other side of the workpiece positioning head 20 has a positioning protrusion 22. The tooling plate 30 is detachably fixed to the workpiece positioning head 20. Supporting arms 31 extend outward from both sides of the tooling plate 30. The supporting arms 31 are used to cooperate with the lifting mechanism of the end of the conveying equipment. Positioning tray 40 is detachably fixed to tooling plate 30, and positioning posts 41 are symmetrically arranged on positioning tray 40.

[0020] As a further improvement, a positioning groove 32 is provided on the contact surface between the tooling plate 30 and the workpiece positioning head 20, and the positioning groove 32 cooperates with the positioning protrusion 22 on the workpiece positioning head 20.

[0021] As a further improvement, the tooling plate 30 is also provided with mounting holes 33.

[0022] As a further improvement, the positioning post 41 is a pin.

[0023] In this embodiment, the workstation tooling assembly consists of three main components that can be detachably installed. The three main components, from top to bottom, are the workpiece positioning head 20, the tooling plate 30, and the tooling positioning tray 40.

[0024] The specific connection method is as follows: 1) The workpiece positioning head 20 and the tooling plate 30 are detachably fixed. The workpiece positioning head 20 cooperates with the positioning groove 32 on the tooling plate 30 through the positioning protrusion 21, so that the workpiece positioning head 20 and the positioning protrusion 21 can be detachably fixed.

[0025] In practical operation, simply align the positioning protrusion 21 of the workpiece positioning head 20 directly with the positioning groove 32 on the tooling plate 30 to achieve detachable fixing of the workpiece positioning head 20 and the tooling plate 30. Moreover, the installation and disassembly are convenient. If the size or type of the workpiece changes, the workpiece positioning head 20 can be redesigned according to the size of the workpiece. Ultimately, this tooling assembly can be applied to various types of workpieces, and one conveying device can correspond to various types of workpieces.

[0026] 2) The tooling plate 30 and the tooling positioning tray 40 are detachably fixed. The tooling plate 30 is provided with mounting hole 33, and the tooling positioning tray 40 is provided with mounting hole 42 corresponding to mounting hole 33. The tooling plate 30 and the tooling positioning tray 40 can be detachably fixed through mounting hole 33 and mounting hole 42.

[0027] In this embodiment, the workstation tooling assembly, through the detachable assembly of the workpiece positioning head 20, tooling plate 30, and tooling positioning tray 40, enables it to meet the transportation needs of tooling assemblies with various size and structural changes with a single transportation setup. Furthermore, the workpiece positioning head 20 cooperates with the positioning groove 32 on the tooling plate 30 through the positioning protrusion 21, making assembly simple and enabling stable transportation of the workpiece.

[0028] During operation, simply place the workstation fixture 10 on the workpiece positioning head 20, and then place the workpiece positioning head 20 on the fixture plate 30 to achieve the fixed placement of the workpiece fixture 10; then place the symmetrically arranged positioning pins 41 on the positioning tray 40 into the insertion holes 511 of the conveyor chain 51 on the circulating hopper 50 (the positions of the positioning pins 41 and the insertion holes 511 are matched).

[0029] Furthermore, the positions of tooling components at adjacent workstations on the circulating material hopper 50 can be adjusted according to actual needs, making operation convenient.

[0030] Example 2 The difference between Example 2 and Example 1 is as follows: 1) The workstation fixture 10 is annular, and the inner surface of the workstation fixture 10 is provided with several internal toothed grooves 11. 2) The outer edge of the positioning protrusion 22 of the workpiece positioning head 20 is provided with at least two tooth grooves 2 corresponding to the inner tooth groove 11.

[0031] 3) The upper end face of the second tooth groove is provided with a guide slope.

[0032] In this embodiment, the outer edge of the positioning protrusion 22 of the workpiece positioning head 20 is provided with two tooth grooves corresponding to the inner tooth groove 11, and the upper end surface of the tooth groove is provided with a guide slope 221.

[0033] During assembly, the guiding slope 221 allows the positioning protrusion 22 of the workpiece positioning head 20 to be easily and smoothly guided into the inner ring of the workstation fixture 10. Once both are in place, the two external toothed grooves 21 precisely engage with the two corresponding internal toothed grooves 11 on the inner circumferential surface of the workstation fixture 10.

[0034] The interlocking of the teeth effectively restricts the workpiece's degrees of freedom in all directions within the horizontal plane, ensuring that the workpiece will not move radially or rotate circumferentially during transport, thus achieving extremely high positioning accuracy and transport stability.

[0035] The required fixing function is achieved with minimal mechanical contact points, greatly reducing frictional loss caused by excessive contact area and significantly reducing the risk of scratches and wear on the inner surface (precision mating surface) of the workpiece. When subjected to transportation vibrations, the toothed interlocking structure can disperse and transmit vibration energy through limited, robust contact points, avoiding wear (fretting wear) caused by micro-vibrations between large-area friction pairs, and further protecting the contact surface of the workpiece.

[0036] Example 3 A multi-station circulating hopper with station tooling components, the circulating hopper 50 includes station tooling components and a conveyor chain 51, the insertion hole 511 on the conveyor chain 51 cooperates with the positioning post 41 on the station tooling components.

[0037] A multi-station circulating silo with station tooling components, the circulating silo 50 includes a frame 52, a circulating conveying system, several station tooling components and a lifting device 53.

[0038] The circulating conveying system mainly includes a closed-loop conveying chain 51 driven by a drive mechanism (such as a motor). The conveying chain 51 is provided with a number of insertion holes 511.

[0039] The workstation tooling assembly engages with the insertion hole 511 on the conveyor chain 51 via the positioning post 41 at its bottom, allowing the workstation tooling assembly to circulate together with the conveyor chain 51.

[0040] Furthermore, the circulating silo is also equipped with a lifting device.

[0041] The lifting devices are symmetrically arranged on both sides of the running path of the conveyor chain 51, corresponding to the loading and unloading stations in the processing system. When the conveyor chain 51 carrying the station tooling assembly reaches the designated loading / unloading station, the conveyor chain 51 stops running. Subsequently, the lifting devices actuate, vertically lifting the station tooling assembly upwards, separating it from the conveyor chain 51 and raising it to a predetermined height. This predetermined height is configured to facilitate precise gripping of the workpiece (or the entire station tooling assembly) by a robotic arm or automated gripping device and transfer it to the next processing station. After gripping, the lifting devices descend, causing the station tooling assembly to fall back onto the conveyor chain 51, or it will fall back after waiting for a new workpiece to be placed, and the system then resumes cyclic operation.

[0042] The aforementioned lifting device can employ any existing technology capable of achieving stable vertical lifting, such as, but not limited to, a cylinder-driven lifting mechanism, a servo motor-driven screw slide mechanism, an electric push rod mechanism, or a scissor lift platform.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
