Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment technology, and more specifically to a four-axis internal zero-point exchange device. Background Technology

[0002] Currently, commonly known CNC machining equipment typically uses four-axis machining equipment. When machining workpieces, four-axis machining equipment often uses zero-point interchange fixtures to clamp the workpieces. Zero-point positioning is a unique positioning and locking device that can keep the zero point unchanged when the workpiece is moved from one station to another, from one process to another, or from one machine tool to another. This eliminates the need to recalibrate the zero point position when changing workpieces.

[0003] In current use, zero-point interchange fixtures for four-axis machining equipment typically require the disassembly and assembly of the flip plate and fixture carrier plate when changing workpieces. The usual disassembly and assembly method involves using a number of screws, which is a slow process and reduces the working efficiency of using zero-point interchange fixtures.

[0025] A zero-point exchange device for a quadcopter, please refer to [link / reference]. Figure 1-3The system includes a four-axis machine tool 100 and a loading machine 200. The four-axis machine tool 100 serves as a CNC machining device, and the loading machine 200 feeds materials onto it. The four-axis machine tool 100 and the loading machine 200 are connected by a signal connection to facilitate coordinated operation between the devices. The loading machine 200 is horizontally positioned and fixed against the front side of the four-axis machine tool 100. The front side of the four-axis machine tool 100 has an opening through which workpieces on the loading machine 200 can enter the four-axis machine tool 100 for processing. The loading machine 200 has a frame 210 that can be fixed to the ground. The frame 210 has two horizontally sliding moving components 220. Each moving component 220 has a tray 230 that can slide back and forth. The tray 230 has a rotatable zero-point exchange table 240. The four-axis machine tool 100 has a processing table 110 that can dock with the tray 230. The processing table 110 has a rotating mechanism 120 that docks with and drives the zero-point exchange table 240 to rotate. The loading machine 200 is fixed to the front of the four-axis machine tool 100; its horizontal structure reduces the floor space required. The area is small enough not to affect operator operation and facilitates loading onto the machine. After the loading machine 200 is fixed in position, the workpiece on the zero-point exchange table 240 can be horizontally moved to the front of the corresponding processing table 110 via the moving component 220. Then, the pallet 230 is pushed onto the processing table 110. After the zero-point exchange table 240 enters the processing table 110, it is rotatable via the rotating mechanism 120. After the zero-point exchange table 240 rotates to the processing angle, the product is processed on the processing table 110. After processing is completed, the pallet 230 can be pulled out to remove the workpiece. Both moving components 220 are equipped with pallets 230 and zero-point exchange tables 240. The two pallets 230 are used alternately to process the workpieces on the two zero-point exchange tables 240 respectively. While one is processing, the other is ready to be loaded. This switching of loading and unloading reduces the downtime of the four-axis machine tool 100, reduces the labor intensity of operators, optimizes the debugging time for switching products, and solves the problem of complex debugging for small batches of multi-variety products. Normally, before processing, the workpiece is usually fixed on the zero-point exchange table 240 by a fixture or directly. The zero-point exchange table 240 ensures that the workpiece remains stable during processing and is consistent with the zero point of the machining coordinate system of the four-axis machine tool 100 through precise positioning, which can reduce the error caused by repositioning and improve the machining accuracy.

[0026] Furthermore, the moving component 220 is provided with a first slide rail 221, and the bottom of the pallet 230 is provided with a groove 231 that mates with the first slide rail 221. The groove 231 is formed by symmetrically fixed groove plates on the bottom of the pallet 230. There are two first slide rails 221, which are symmetrically arranged on the moving component 220. The pallet 230 can be inserted into the first slide rail 221 from the front side of the moving component 220 by aligning it with the groove 231. The first slide rail 221 is provided with multiple rollers that contact the bottom surface of the pallet 230. Through the action of the rollers, the operator can easily pull the pallet 230 back and forth, which is convenient for loading and unloading operations. Generally, a locking structure can also be provided between the moving component 220 and the pallet 230 to fix the pallet 230 on the moving component 220 when preparing to load materials. The processing table 110 is equipped with a second slide rail 111, the structure of which is similar to that of the first slide rail 221. The front side of the processing table 110 is equipped with a connecting slide rail 112 corresponding to the second slide rail 111. The connecting slide rail 112 extends forward to facilitate docking with the tray 230. Both the second slide rail 111 and the connecting slide rail 112 are equipped with rollers. When loading, the moving component 220 moves to the front side of the processing table 110, and the tray 230 is pushed backward and can slide onto the processing table 110 through the connecting slide rail 112 and the second slide rail 111 to achieve a smooth docking and make the loading operation more convenient.

[0027] Furthermore, the tray 230 is provided with two vertical support plates 232 connecting the two sides of the zero-point exchange table 240. A rotating shaft structure is provided so that the zero-point exchange table 240 can be rotatably connected to the vertical support plates 232. The rotating mechanism 120 is fixed to the right side of the processing table 110. The rotating mechanism is provided with a drive motor 121 that can be connected to and drive the zero-point exchange table 240 to rotate. The left side of the drive motor 121 and the right side of the zero-point exchange table 240 are provided with matching connection structures. The drive motor 121 is connected to and drives the zero-point exchange table 240 to rotate through the connection structures. The processing table 110 is equipped with a locking device 114 that can lock the connected tray 230. A cylinder assembly that can drive the tray 230 to move up and down is connected below the processing table 110. The cylinder assembly is not shown in the attached figure. The cylinder assembly and the locking device 114 are existing technologies and will not be described in detail. They are designed to cooperate with the rotating mechanism 120 to complete the loading and unloading. The processing table 110 is raised and lowered to the corresponding height by the cylinder assembly. The rotating mechanism 120 is connected to the zero point exchange table 240 and rotates to the processing angle. The locking device 114 locks the tray 230 to fix it in place. The machine tool starts processing. After processing is completed, the tray 230 can be raised and removed. Another tray 230 can be pushed into the machine tool for further processing.

[0028] Furthermore, the frame 210 is equipped with a horizontally mounted heavy-duty linear guide rail assembly 211. The two moving components 220 can be slidably connected to the frame 210 laterally through the heavy-duty linear guide rail assembly 211. The heavy-duty linear guide rail assembly 211 includes two linear guide rails, and the moving component 220 is equipped with multiple corresponding sliders, allowing the moving component 220 to slide horizontally on the frame 210. One of the two linear guide rails faces upward and the other faces forward, ensuring support and connection stability, and guaranteeing smooth sliding of the moving component 220. Using heavy-duty linear guide rails as guides has advantages such as large load capacity and smooth movement. The frame 210 is equipped with multiple positioning buckles 212, and the moving component 220 is equipped with a positioning handle 222 that can cooperate with the positioning buckles 212. Generally, the frame 210 needs to be equipped with three positioning buckles 212, located at the bottom of the upper horizontal slide rail. These three positioning buckles are distributed on the left, right, and center sides of the frame 210. When the moving component 220 reaches the position of the three positioning buckles 212, it can be fixed by the positioning handle 222, preventing the moving component 220 from sliding when not in use and ensuring stability during loading. The positioning handle 222 is connected by a pivot and a spring. Under the action of the spring, the positioning handle 222 maintains an upward force. By pulling down the positioning handle 222, the moving component 220 can be slid away from the positioning buckles 212. The positioning handle 222 can also be gripped by the operator to push the moving component 220 to slide. The bottom of the frame 210 is provided with multiple feet 213 for supporting and fixing to the ground. The feet 213 can stably support the frame 210, and the frame 210 can be fixed to the ground by screws on the feet 213, so that the feeder 200 remains stable and ensures accurate alignment with the four-axis machine tool 100.
