[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments:

[0029] like Figures 1 to 7 A multi-station flipping fixture is shown, comprising: a base 100, a four-jaw chuck 110 mounted on the top and end face of the base 100, a T-plate 120 clamped on the top of the four-jaw chuck 110, an extension plate 130 bolted to the top of the T-plate 120, a clamp 140 mounted on the top of the extension plate 130, and a collection assembly 200 for collecting debris provided on the outer side of the T-plate 120.

[0030] The collecting component 200 includes an outer cone 210 sleeved on the outside of the T-plate 120. Multiple sets of arc-shaped plates 240 are rotatably provided at the top edge of the outer cone 210. The multiple sets of arc-shaped plates 240 are evenly distributed along the arc trajectory of the outer cone 210. An inner cone 220 is slidably provided at the bottom of the outer cone 210. A square opening 230 matching the external dimensions of the T-plate 120 is reserved at the center of the inner cone 220. A filter screen 260 is movably fitted on the inner wall of the inner cone 220. A drain hole 270 for discharging coolant is opened at the bottom of the inner cone 220.

[0031] Select a suitable thickness of the heightening plate 130 and fix it on the top of the T plate 120. Fix the clamp 140 on the top of the heightening plate 130. At the same time, put the T plate 120 into the outer cone barrel 210 from top to bottom. At this time, the T plate 120 and the heightening plate 130 are located in the square opening 230, while the clamp 140 is located above the center of the inner cone barrel 220. Then, place the T plate 120 in the middle of the top of the four-jaw chuck 100. Use tools to control the four jaws to converge and clamp the T plate. Finally, push the arc-shaped piece 240 inward. Multiple sets of arc-shaped pieces 240 will bend inward, thereby reducing the space at the top of the outer cone barrel 210 and preventing chips and coolant from splashing around during cutting. This effectively prevents chips from entering the four-jaw chuck 110 and causing difficulties in manual cleaning.

[0032] Alternatively, the T-plate 120 can be placed in the four-claw baking tray 110 on the end face of the base 100 to process the side of the workpiece, thereby saving the trouble of changing the workpiece and indirectly improving the processing efficiency of the workpiece.

[0033] With the cooperation of the outer cone 210 and the top arc-shaped plate 240, the debris falls downward into the inner cone 220, while the filter screen 260 blocks the metal debris, keeping it separate from the coolant, making it easier to remove the metal debris and coolant separately later.

[0034] Please refer to this carefully. Figure 4 The filter screen 260 is inclined from the edge to the center, and the center of the filter screen 260 is raised.

[0035] The inclined filter screen 260 prevents the processing debris from spreading flat on the top of the filter screen 260 and causing blockage. Combined with the raised center position, the metal debris is located at the lowest point of the filter screen 260 surface, allowing coolant to pass through from the higher area of ​​the filter screen 260.

[0036] Please refer to this carefully. Figure 3 The top of the inner cone 220 is fixed with a drain pipe 250 that is connected to the drain hole 270, and a sealing cap is threaded to the bottom outer wall of the drain pipe 250.

[0037] The drain pipe 250 guides the coolant to a designated container, while the sealing cap blocks the drain pipe 250, allowing the coolant to be temporarily stored in the inner cone 220.

[0038] Please refer to this carefully. Figure 6 Multiple sets of constraint blocks 221 are fixed to the curved outer wall of the inner cone barrel 220, and constraint grooves 211 are provided on the inner wall of the outer cone barrel 210 for the constraint blocks 221 to slide.

[0039] By using the constraint block 221 and the constraint groove 121 to limit the placement of the inner cone 220, the inner cone 220 will not rotate when the outer cylinder 210 is sleeved on the outside of the T plate 120, so that the placement of the outer cone 220 is unrestricted.

[0040] Please refer to this carefully. Figure 1 and Figure 7 The arc-shaped plate 240 is rotated to the top of the outer cone 210 by a damping shaft. The two adjacent sets of arc-shaped plates 240 are arranged in an inward and outward staggered manner. The outer wall of the adjacent arc-shaped plates 240 on the same side is reserved with a notch 241.

[0041] The damping shaft can increase the connecting force between the arc-shaped plate 240 and the outer cone barrel 210, ensuring that the arc-shaped plate 240 can stand upright on the top of the outer cone barrel 210, so that the workpiece can be picked up and put down without restriction. The notch 241 ensures that it can converge towards the center without restriction, and can reduce the top diameter of the outer cone barrel 210.

[0042] Please refer to this carefully. Figure 1 The bottom of the outer cone barrel 210 is in contact with the jaws on the top of the four-jaw chuck 110.

[0043] The cone 210 provides support, allowing it to be stably positioned on top of the four-jaw chuck 110, and collects metal scraps and coolant.

[0044] The T-plate 120 is bolted to the heightening plate 130 from the bottom, and the heightening plate 130 and the clamp 140 are detachably connected by screws.

[0045] The heightening plate 130 can be easily disassembled and replaced with a heightening plate suitable for the workpiece thickness, allowing the cutting tool on the machine tool to process the workpiece, and the collection component 200 can be easily removed to clean the internal metal shavings and coolant.

[0046] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
