Description

Technical Field

[0001] This utility model relates to the field of automated machine tool loading and unloading technology, specifically to a machine tool loading and unloading machine. Background Technology

[0002] In modern manufacturing, machine tools are the core equipment for precision machining of parts. To improve production efficiency, reduce labor costs, and ensure operational safety, automating the loading and unloading of machine tools has become an inevitable trend, and machine tool loading and unloading machines are key equipment for realizing this process.

[0003] In existing technologies, common automatic material handling solutions for machine tools are usually completed manually or by robotic arms. When robotic arms are used, the blanks are usually placed manually in advance and then picked up by the robotic arm. The finished products are also picked up by the robotic arm and placed in a fixed position, and then processed manually. There is no good integration with the conveying mechanism. Some factories have combined the conveying mechanism with the robotic arm, but the conveying mechanism usually uses a single-layer belt conveyor line. Generally, two independent conveyor lines are set up to handle blank input and finished product output respectively, which is lacking in space utilization and efficiency.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a machine tool loading and unloading machine. By setting up a transverse conveying component with an upper conveyor belt and a lower conveyor belt, combined with a pair of longitudinal conveying components that can transfer workpieces between the upper and lower conveyor belts, and a robotic arm equipped with a special support mechanism clamping component at the end, the machine tool can realize the cyclic conveying of blanks and finished products in the same area, which significantly improves space utilization and production efficiency.

[0006] Technical Solution: This utility model provides a machine tool loading and unloading machine including a conveying mechanism and a robot arm. The robot arm is used to grab a blank part from the conveying mechanism onto the machine tool. After the machine tool processes it into a finished part, the robot arm grabs the finished part back to the conveying mechanism. The end of the robot arm is equipped with a gripping component, which is adapted to the blank part and the finished part. The conveying mechanism includes a pair of longitudinal conveying components and a transverse conveying component. The transverse conveying component includes a frame, an upper conveyor belt, and a lower conveyor belt. The upper and lower conveyor belts are arranged sequentially on the frame in a vertical direction. The pair of longitudinal conveying components are used to transport the blank part and the finished part between the upper and lower conveyor belts. The conveying mechanism includes a pair of longitudinal conveying components and a transverse conveying component. The transverse conveying component has an upper conveyor belt and a lower conveyor belt arranged vertically on its frame. The longitudinal conveying component can transport blanks and finished products between the upper and lower conveyor belts, forming a three-dimensional material transport network. It can orderly transport blanks to the gripping position of the robot arm, and at the same time, retrieve finished products from the robot arm and transport them to the subsequent processing stage, ensuring the continuous flow of materials during the machine tool's loading and unloading process. The gripping component installed at the end of the robot arm is adapted to the blanks and finished products, and can achieve stable gripping according to the shape, size and other characteristics of the workpiece.

[0007] Furthermore, in this application, a machine tool material handling and unloading machine includes a gripping assembly comprising a mounting plate connected to a rotating shaft at the end of a robotic arm. A pair of clamping plates are mounted on the mounting plate along the axial direction of the rotating shaft, and a pair of horizontal plates are positioned between the clamping plates. These horizontal plates are radially arranged along the rotating shaft, and a pair of first cylinders are mounted on each horizontal plate. A supporting mechanism is mounted at the output end of each first cylinder. A pair of blank holes are provided on the blank workpiece, and the supporting mechanism is used to extend into the blank holes, expand, and then abut against the inner wall of the blank holes. The gripping assembly enables targeted gripping of workpieces with holes. The mounting plate is connected to the rotating shaft of the robotic arm and its angle can be adjusted with the rotating shaft. The pair of clamping plates and the horizontal plates form a support frame. The first cylinders drive the supporting mechanism to extend and retract radially along the rotating shaft, precisely matching the position of the blank holes on the blank workpiece. The expanding action forms a stable abutment against the inner wall of the hole, making it suitable for gripping workpieces with specific hole structures.

[0008] Furthermore, in this application, a machine tool material handling and unloading machine includes a supporting mechanism comprising a body on which a pair of parallel clamping arms are mounted. Each clamping arm has a detachably mounted jaw. The body drives the clamping arms to move towards or away from each other. Initially, the pair of clamping arms are closed together. When the jaws extend into the blank hole, the body drives the clamping arms to move away from each other, at which point the jaws abut against the inner wall of the blank hole. When the blank is transferred to the machine tool processing position, the body drives the clamping arms to move towards each other, at which point the blank is released. The supporting mechanism achieves precise opening and closing of the jaws: initially, the clamping arms are closed, facilitating unobstructed insertion of the jaws into the blank hole; after entering the hole, the body drives the clamping arms to move away from each other, and the jaws open to abut against the inner wall of the hole, forming a stable grip; upon reaching the machine tool processing position, the clamping arms move towards each other to retract the jaws, achieving interference-free release of the workpiece.

[0009] Furthermore, in a machine tool material handling and unloading machine according to this application, the chuck is L-shaped, with one side mounted on the clamp arm and the other side extending outward, and a rubber sleeve fitted on the extension. The rubber sleeve fitted on the extension has elastic deformation characteristics, preventing the metal chuck from directly contacting the inner wall of the workpiece when the chuck abuts against the inner wall of the blank hole, thus preventing indentation.

[0010] Furthermore, in a machine tool material handling machine according to this application, both the upper and lower conveyor belts are equipped with several trays, and each tray has a set of limiting protrusions. The blank and finished parts are confined between the protrusions. The precise positioning of the limiting protrusions allows the robot arm to directly grasp the workpiece using preset coordinates without relying on a vision system for secondary alignment.

[0011] Furthermore, in this application, a machine tool loading and unloading machine includes a longitudinal conveying component comprising a frame and a linear drive mechanism. The frame is equipped with a set of slide rails, each with a corresponding slider. A short conveyor belt is mounted on the slider, parallel to both the upper and lower conveyor belts. The linear drive mechanism is mounted on the frame and connected to the short conveyor belt, driving its up-and-down movement. The upper conveyor belt transports blanks, with a pallet carrying the blanks being moved to a fixed position on the short conveyor belt. A robotic arm then picks up the blanks for machine tool processing. After processing, the finished product is picked up and placed on the pallet. The short conveyor belt then moves down parallel to the lower conveyor belt, reversing the flow and moving the pallet containing the finished product onto the lower conveyor belt. A worker, standing away from the robotic arm, removes the finished product and places the blank on an empty pallet. Finally, the short conveyor belt moves up again, moving the pallet containing the blank back onto the upper conveyor belt. The worker's loading and unloading operations can also be completed by the robotic arm, achieving fully automated operation.

[0012] Furthermore, in this application, a machine tool loading and unloading machine includes a linear drive mechanism comprising a drive motor, an adjusting seat, and a lead screw. The drive motor is mounted on the upper end of a vertical frame, and its output end is connected to the lead screw. The adjusting seat passes through the lead screw and is connected to the short conveyor belt. The output torque of the drive motor is converted into linear motion of the adjusting seat through the lead screw, thereby realizing the vertical lifting and lowering of the short conveyor belt.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] 1. The machine tool loading and unloading machine of this utility model is equipped with a transverse conveying component having an upper conveyor belt and a lower conveyor belt, and a pair of longitudinal conveying components that can transfer workpieces between the upper and lower conveyor belts, thus constructing a three-dimensional material transfer network. Raw parts and finished parts can be transported in an orderly cycle within the same area, which greatly improves space utilization and avoids the dependence on large areas of space required by traditional transport methods. Furthermore, the continuous flow of workpieces ensures the compactness of the production process, effectively improving production efficiency and shortening the production cycle.

[0015] 2. The machine tool loading and unloading machine of this utility model works in coordination with the pallet positioning system through the clamping component with end support mechanism. This achieves non-destructive gripping of workpieces with holes and eliminates the need for secondary alignment by the robot arm. It improves gripping accuracy and production efficiency while ensuring the surface quality of the workpiece. Attached Figure Description
