[0021] For example, see Figures 1 to 5 The present embodiment provides a double-station alternating grinding device, which includes a workbench 1, a grinding device 2, a bracket 3, an X-axis moving mechanism 4, a first Y-axis moving mechanism 5, a second Y-axis moving mechanism 6, a Z-axis moving mechanism 7, a grinding sheet replacement device 8, a first grinding table 9 and a second grinding table 10.

[0022] The first Y-axis moving mechanism 5, the second Y-axis moving mechanism 6 and the grinding sheet replacement device 8 are arranged on the workbench 1. Preferably, a guardrail 11 is provided on the periphery of the workbench 1, and an operation opening is provided on the front of the guardrail 11. It is used to protect the safety of the operator and prevent accidental contact with the equipment running parts. An operation opening is provided on the front of the guardrail 11, which is convenient for the operator to observe the equipment running status and perform necessary operations or maintenance.

[0023] The first grinding table 9 and the second grinding table 10 are respectively arranged on the first Y-axis moving mechanism 5 and the second Y-axis moving mechanism 6, and are driven by them to move in the Y-axis direction. Specifically, the first Y-axis moving mechanism 5 includes a Y-axis substrate 51, a Y-axis slide rail 52, a Y-axis slider 53, a Y-axis slide seat 54, a Y-axis motor 55 and a Y-axis ball screw pair 56. The Y-axis slide rail 52 is arranged on the Y-axis substrate 51, and the Y-axis slide seat 54 is movably arranged on the Y-axis slide rail 52 through the Y-axis slider 53. The Y-axis motor 55 is arranged on the Y-axis substrate 51, and drives the Y-axis slide seat 54 to reciprocate in the Y-axis direction through the Y-axis ball screw pair 56. When the Y-axis motor 55 rotates, the Y-axis ball screw pair 56 converts the rotational motion into the linear reciprocating motion of the Y-axis slide seat 54, thereby driving the first grinding table 9 to move in the X-axis direction.

[0024] The first grinding table 9 includes a lower seat 91 and an upper seat 92. The upper seat 92 is overlapped with the lower seat 91 to form a vacuum chamber. The upper surface of the upper seat 92 is provided with a placement position 921 consistent with the outer contour of the workpiece, and the bottom surface of the placement position 921 is provided with a suction hole connected to the vacuum chamber. The lower seat 91 is provided with a connecting hole connected to the vacuum chamber, which can be connected to a vacuum source, so that the workpiece is firmly adsorbed on the placement position 921 by vacuuming.

[0025] In this embodiment, the structure of the second Y-axis moving mechanism 6 is preferably consistent with the structure of the first Y-axis moving mechanism 5. The structure of the second grinding table 10 is preferably consistent with the structure of the first grinding table 9, which is conducive to standardized production and easy to produce.

[0026] The X-axis moving mechanism 4 is arranged on the workbench 1 through the bracket 3. Specifically, the X-axis moving mechanism 4 includes an X-axis substrate 41, an X-axis slide rail 42, an X-axis slider 43, an X-axis slide seat 44, an X-axis motor 45 and an X-axis ball screw pair 46. The X-axis slide rail 42 is arranged on the X-axis substrate 41. The X-axis slide seat 44 is movably arranged on the X-axis slide rail 42 through the X-axis slider 43. The X-axis motor 45 is arranged on the X-axis substrate 41 and drives the X-axis slide seat 44 to reciprocate in the X-axis direction through the X-axis ball screw pair 46. When the X-axis motor 45 rotates, the X-axis ball screw pair 46 converts the rotational motion into the linear reciprocating motion of the X-axis slide seat 44, thereby driving the grinding device 2 to move in the X-axis direction. The bracket 3 includes two pillars 31, the lower ends of the two pillars 31 are fixed to the workbench 1 through a fixing seat 32, and the upper ends are connected to the two ends of the back side of the X-axis substrate 41 through a mounting seat 33, so that the mounting is firm and the structural stability is good.

[0027] The grinding device 2 is arranged on the X-axis moving mechanism 4 through the Z-axis moving mechanism 7, and is driven by the X-axis moving mechanism 4 to reciprocate between the first grinding table 9, the second grinding table 10 and the grinding sheet replacement device 8. The grinding device 2 is preferably a pneumatic angle grinder, which uses compressed air to drive the grinding sheet to rotate at high speed, and is suitable for high-intensity grinding operations.

[0028] The grinding sheet replacement device 8 includes a base 81, a top seat 82, a floating seat 83, a buffer component 84, a guide rod 85, a guide sleeve seat 86 and a material unloading blade 87. A plurality of guide rods 85 are vertically arranged on the base 81 and enclose a sheet storage area for storing grinding sheets. The top seat 82 is arranged on the guide rods 85 and is provided with a sheet taking opening corresponding to the sheet storage area. The edge of the top seat 82 is provided with a material unloading notch. The material unloading blade 87 is horizontally arranged on the material unloading notch. The floating seat 83 is movably arranged on the guide rods 85 through the guide sleeve seat 86 and can freely rise and fall in the sheet storage area. The buffer component 84 is located on the base 81 and abuts against the bottom surface of the floating seat 83. The buffer component 84 is a cylinder or a spring, which can provide appropriate buffering force to reduce the possibility of the grinding disc on the grinding device 2 being damaged due to impact when it is pressed downward and attached to the grinding sheet.

[0029] The grinding sheet is a piece of sandpaper or scouring pad with Velcro on the back. Several grinding sheets are stacked and placed on the floating seat 83. When the grinding sheet needs to be replaced, the X-axis moving mechanism 4 and the Z-axis moving mechanism 7 cooperate to drive the grinding device 2 to move directly to the unloading blade 87, so that the pasting position between the grinding disc on the grinding device 2 and the old sandpaper is just aligned with the unloading blade 87. The X-axis moving mechanism 4 continuously drives the grinding device 2 to move to the unloading blade 87, so that the unloading blade 87 is inserted between the grinding disc and the old sandpaper until the unloading blade 87 separates the old sandpaper from the grinding disc, so as to achieve the purpose of peeling off the old sandpaper; at this time, the grinding disc of the grinding device 2 also happens to move to the sheet taking opening position, and the Z-axis moving mechanism 7 drives the grinding device 2 downward, so that the grinding disc is pressed on the grinding sheet located on the floating seat 83, and the new sandpaper is pasted, and no manual operation is required, so that the automatic replacement of sandpaper is realized. Preferably, the unloading blade 87 is fixed on the upper surface of the top seat 82, and the unloading blade 87 and the film taking opening are arranged in sequence along the X-axis direction, so that when the X-axis moving mechanism 4 drives the grinding device 2 to move toward the film taking opening, the unloading blade 87 can be used to peel off the old sandpaper, which effectively simplifies the peeling action and further improves work efficiency.

[0030] During operation, the first grinding table 9 and the second grinding table 10 are both located at the loading and unloading position near the operation opening in the initial state. The workpiece is first placed on the first grinding table 9, and the first Y-axis moving mechanism 5 drives the first grinding table 9 to move to the first grinding station. The Z-axis moving mechanism 7 drives the grinding device 2 downward to grind the workpiece on the first grinding table 9; at this time, the grinding time of the first grinding station can be used to place the workpiece on the second grinding table 10, and the second Y-axis moving mechanism 6 directly drives the second grinding table 10 to move to the second grinding station. When the first grinding station is finished, the grinding device 2 is driven to move to the second grinding station and grind the workpiece on the second grinding table 10 through the cooperation of the Z-axis moving mechanism 7 and the X-axis moving mechanism 4. Then, the first Y-axis moving mechanism 5 drives the first grinding table 9 to move to the loading and unloading position near the operation opening. At this time, the workpiece can be placed on the first grinding table 9 by utilizing the grinding time of the second grinding station, and the second grinding table 10 can be directly driven to move to the second grinding station by the second Y-axis moving mechanism 6. In this way, the entire production process can be carried out seamlessly, avoiding interruptions and pauses, realizing alternate processing of workpieces, and improving equipment utilization and production efficiency.
