Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to an automated feeding fixture assembly. Background Technology

[0002] Fixtures are devices used to fix, position, and support workpieces during machining, ensuring that the workpiece remains stable during machining, thereby guaranteeing machining accuracy and efficiency.

[0003] The design and selection of fixtures directly affect machining quality, production efficiency, and operational safety.

[0004] Robots working with fixtures can perform complex machining of workpieces from multiple angles and in multiple postures.

[0005] For example, a six-axis robot is a highly flexible industrial robot with six rotary joints (or axes), allowing it to perform complex movements and operations in three-dimensional space.

[0006] This design enables six-axis robots to mimic the movements of a human arm, thus enabling them to perform highly repetitive and labor-intensive automated tasks. As a result, six-axis robots can significantly improve the speed and efficiency of production lines.

[0007] Moreover, six-axis robots can complete tasks with extremely high precision, reducing human error and ensuring consistent product quality.

[0008] Therefore, six-axis robots can provide modern manufacturing with multifunctional, efficient, and easily integrated solutions, helping companies cope with ever-changing market demands and technological challenges.

[0009] However, when existing fixtures work in conjunction with robots, the fixtures are usually placed directly in the robot's working area. This requires operators to enter the robot's working area to clamp the workpiece, which is not only cumbersome and inconvenient but also poses safety hazards. Furthermore, because the fixtures are stationary, the robot needs to perform more complex commands to complete the processing of the workpiece. Utility Model Content

[0010] The purpose of this invention is to address the aforementioned problems in existing technologies by providing an automated feeding fixture assembly that is highly automated and has a compact structure.

[0011] To achieve the above objectives, this utility model can be implemented through the following technical solutions:

[0012] An automated feeding fixture assembly includes a frame, characterized in that it further includes a conveyor rail, a base, a turntable assembly, and a drive component. The conveyor rail is laterally disposed on the upper part of the frame, the base is connected to the conveyor rail, the drive component is disposed between the base and the frame, and the drive component can drive the base to translate along the conveyor rail. The lower part of the turntable assembly is connected to the base, the turntable assembly has a positioning component for positioning the workpiece, and the turntable assembly can rotate relative to the base by a set angle.

[0013] In the aforementioned automated feeding fixture assembly, the conveying guide rail includes guide rail one and guide rail two, which are symmetrically located on both sides of the frame, and both guide rail one and guide rail two are connected to the lower part of the base.

[0014] In the aforementioned automated feeding fixture assembly, the frame is equipped with a position sensor that can be triggered when the base moves along the conveyor rail.

[0015] In the aforementioned automated feeding fixture assembly, a limit stop is fixedly connected to one end of the guide rail, and the base can touch the limit stop after moving along the guide rail.

[0016] In the aforementioned automated feed fixture assembly, the limiting stop includes a block-shaped body, the lower part of which has a connecting recess that matches the guide rail, a flexible limiting post connected to the side of the body, and a positioning pin threaded to the end of the body. The inner end of the positioning pin is located at the connecting recess and presses against one side of the guide rail.

[0017] In the aforementioned automated feeding fixture assembly, the body has a recessed connecting hole, and the inner end of the aforementioned limiting post matches the connecting hole and is embedded in the connecting hole.

[0018] In the aforementioned automated feeding fixture assembly, the connecting hole and the limiting pin form a limiting unit on the body. There are two limiting units, which are symmetrically located on both sides of the body.

[0019] The aforementioned automated feeding fixture assembly also includes a cover plate, the end of which is fixedly connected to the end of the frame and covers guide rail one and guide rail two.

[0020] In the aforementioned automated feeding fixture assembly, the base has an upwardly protruding connecting section, the lower part of the turntable assembly is fixedly connected to the connecting section, an avoidance channel is formed between the upper part of the base and the turntable assembly, and the middle part of the cover plate passes through the avoidance channel.

[0021] In the aforementioned automated feeding fixture assembly, the driving component includes a motor, a right-angle reducer, a gear, and a rack. The right-angle reducer is fixedly connected to the base, the motor is fixedly connected to the right-angle reducer, the gear is fixedly connected to the shaft of the right-angle reducer, and the rack is fixedly connected to the frame, meshing with the gear.

[0022] Compared with existing technologies, this automated feeding fixture assembly uses both position sensors and limit stops for dual limiting, effectively improving its stability. In the initial state, the turntable assembly for clamping the workpiece is located at one end of the frame. After the workpiece is clamped, the turntable assembly moves along the conveyor rail to the other end of the frame, demonstrating a high degree of automation.

[0023] In its practical application, one end of the frame is located outside the work area, while the other end is located inside. This allows operators to easily clamp and unclamp workpieces on the turntable assembly outside the work area. Once the turntable assembly is inside the work area, the workpieces clamped on it can be processed stably and quickly. It is evident that this design offers a high degree of automation, effectively eliminates the need for operators to be physically present in the work area, improves safety, and possesses significant practical value.

[0024] In addition, the cover plate in the whole assembly covers guide rail one and guide rail two, effectively preventing guide rail one and guide rail two from being exposed. This not only improves the compactness of the structure, but also provides a good dustproof effect, and appropriately improves its safety and stability.

[0025] Meanwhile, since the turntable assembly can rotate relative to the base, the rotating turntable assembly, when working with the robot, enables the workpiece to have a higher degree of freedom, thereby allowing for stable processing of various positions on the workpiece.

[0034] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0035] like Figure 1-6 As shown, this automated feeding fixture assembly includes a frame 1, a conveyor rail, a base 3, a turntable assembly 4, and a drive component. The conveyor rail is horizontally arranged on the upper part of the frame 1. The base 3 is connected to the conveyor rail. The drive component is arranged between the base 3 and the frame 1. The drive component can drive the base 3 to move horizontally along the conveyor rail. The lower part of the turntable assembly 4 is connected to the base 3. The turntable assembly has a positioning component for positioning the workpiece, and the turntable assembly 4 can rotate relative to the base 3 by a set angle.

[0036] The turntable assembly 4 is a commercially available component, which can rotate the workpiece located on it by a set angle. Therefore, the specific technical solution of the turntable assembly 4 will not be described in detail in this embodiment.

[0037] In the initial state, the base 3 and the turntable assembly 4 are located at one end of the frame 1, and this end of the frame 1 is outside the processing area. Operators can quickly and safely load and unload workpieces from the turntable assembly 4 outside the processing area.

[0038] Once the workpiece is stably mounted on the turntable assembly 4, the drive unit moves the base 3 from one end of the frame 1 to the other end. The turntable assembly 4, located on the base 3, moves together with the base 3, ultimately allowing the turntable assembly 4 and the workpiece on it to quickly enter the working area.

[0039] It can be seen that this clamping assembly can prevent operators from entering work areas with safety hazards, which not only effectively improves work safety, but also eliminates the need to transport workpieces over long distances, thus improving work efficiency and reducing the labor intensity of operators.

[0040] The conveying guide rails include guide rail 8 and guide rail 9, which are symmetrically located on both sides of the frame 1. Both guide rail 8 and guide rail 9 are connected to the lower part of the base 3.

[0041] Guide rail 1 (8) and guide rail 2 (9) are symmetrically located on both sides of the frame 1. The base 3 is connected to the guide rail slider 14. Guide rail 1 (8) and guide rail 2 (9) have corresponding guide rail sliders 14, and both guide rail 1 (8) and guide rail 2 (9) are connected to their respective guide rail sliders 14. The guide rail sliders 14 can appropriately increase the contact area between the base 3 and guide rail 1 (8) and between the base 3 and guide rail 2 (9), ultimately improving the stability of the base 3's movement.

[0042] The frame 1 is equipped with a position sensor 10, which can be triggered when the base 3 moves along the conveyor rail.

[0043] The position sensor 10 is connected to the drive component via a signal line. Once the position sensor is touched by the position sensor 10, a signal is sent to stop the drive component from moving, thus preventing the base 3 from moving excessively.

[0044] A limit stop 11 is fixedly connected to the end of the guide rail 8, and the base 3 can touch the limit stop 11 after moving along the guide rail 8.

[0045] The limit stop 11 serves as a secondary safety measure. When the position sensor 10 malfunctions, the limit stop 11 can block the base, preventing the base 3 from falling.

[0046] The limiting stop 11 includes a block-shaped body 11a. The lower part of the body 11a has a connecting recess 11b that matches the guide rail 8. A flexible limiting post 11c is connected to the side of the body 11a. A positioning pin 11d is threaded to the end of the body 11a. The inner end of the positioning pin 11d is located at the connecting recess 11b and the inner end of the positioning pin 11d presses against the side of the guide rail 8.

[0047] Body 11a has two functions:

[0048] Firstly, it provides sufficient mounting space for the limiting post 11c;

[0049] Secondly, it is used to fix the guide rail 8, so that the limiting post 11c is indirectly fixedly connected to the guide rail 8.

[0050] The body has a recessed connection hole, and the inner end of the limiting post matches the connection hole and is embedded in the connection hole.

[0051] The connection hole further improves the connection stability between the limiting post 11c and the body 11a. In this embodiment, the limiting post 11c is made of rubber.

[0052] The aforementioned connecting hole and limiting pin 11d form a limiting unit on the body 11a. There are two limiting units, which are symmetrically located on both sides of the body.

[0053] The two symmetrically arranged limiting units can ensure that the base 3 is stably subjected to force.

[0054] It also includes a cover plate 12, the end of which is fixedly connected to the end of the frame 1 and covers the first guide rail 8 and the second guide rail 9.

[0055] Since both guide rail 18 and guide rail 29 are covered by cover plate 12, dust or other debris is prevented from accumulating on guide rail 18 and guide rail 29, effectively improving the moving stability of base 3.

[0056] The base 3 has an upwardly protruding connecting section 3a. The lower part of the turntable assembly 4 is fixedly connected to the connecting section 3a. An avoidance channel is formed between the upper part of the base 3 and the turntable assembly 4. The middle part of the cover plate 12 passes through the avoidance channel.

[0057] Since the end of the cover plate 12 is fixedly connected to the end of the frame 1, and the base 3 is limited, the base 3 will not move to the end of the frame 1. Therefore, this forms an effective avoidance, whereby the cover plate 12 not only covers the guide rail 8 and the guide rail 9, but also prevents the cover plate 12 from touching and getting stuck with the base 3.

[0058] The drive component includes a motor 15, a right-angle reducer 16, a gear 17, and a rack 18. The right-angle reducer 16 is fixedly connected to the base 3, the motor 15 is fixedly connected to the right-angle reducer 16, the gear 17 is fixedly connected to the shaft of the right-angle reducer 16, and the rack 18 is fixedly connected to the frame 1. The rack 18 meshes with the gear 17.

[0059] The motor 15 indirectly drives the gear 17 to run on the rack 18, enabling the base 3 to move smoothly along the conveyor rail on the frame 1. The right-angle reducer 16 is provided to avoid the motor 15 occupying too much space on the frame 1.

[0060] This automated feeding fixture assembly employs both a position sensor and limit stops for dual limiting, effectively improving its stability. Initially, the turntable assembly for clamping the workpiece is located at one end of the frame. After the workpiece is clamped, the turntable assembly moves along the conveyor rail to the other end of the frame, demonstrating a high degree of automation.

[0061] In its practical application, one end of the frame is located outside the work area, while the other end is located inside. This allows operators to easily clamp and unclamp workpieces on the turntable assembly outside the work area. Once the turntable assembly is inside the work area, the workpieces clamped on it can be processed stably and quickly. It is evident that this design offers a high degree of automation, effectively eliminates the need for operators to be physically present in the work area, improves safety, and possesses significant practical value.

[0062] In addition, the cover plate in the whole assembly covers guide rail one and guide rail two, effectively preventing guide rail one and guide rail two from being exposed, providing a good dustproof effect, and also appropriately improving its safety and stability.

[0063] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application are the same as or can be implemented using existing technologies, and will not be described in detail here.
