DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5 A drilling fixture includes a base 100, on which a support member 200 for carrying a workpiece 101 and a fixing member 300 for fixing the workpiece 101 on the support member 200 are provided. Specifically, the support member 200 includes a support plate 210, and the support plate 210 includes a first plate body 211, the first plate body 211 is provided with a second plate body 212 extending vertically, and the second plate body 212 is provided with a third plate body 213 extending horizontally so that the third plate body 213 is suspended. The first plate body 211 is detachably connected to the base 100, and the workpiece 101 is placed on the third plate body 213, so that the workpiece 101 is suspended relative to the base 100, so as to facilitate the drilling equipment to reduce the drilling of the workpiece 101 in the horizontal direction and the vertical direction. At the same time, through the movement of multiple support members 200, workpieces 101 of different shapes can be supported, so as to adapt to workpieces 101 of different shapes.

[0023] The base 100 is provided with a plurality of guide grooves 110, and the guide grooves 110 include a groove body 111 and an opening 112 disposed on the surface of the base 100 so that the groove body 111 is connected to the outside. The fixing member 300 includes a fixing plate 370, and a telescopic rod 330 threadedly matched with the fixing plate 370 is provided on the fixing plate 370, and the telescopic rod 330 extends into the groove body 111 through the opening 112, and a second stopper 331 is provided at one end of the telescopic rod 330 extending into the groove body 111, and the diameter of the second stopper 331 is greater than the width of the opening 112 so that it can be locked with the opening 112. When fixing the workpiece 101, the fixing plate 370 fits with the edge of the upper surface of the workpiece 101, and the telescopic rod 330 is rotated to make the second stopper 331 move upward and lock with the opening 112, so that the fixing plate 370 is locked with the workpiece 101 and the movement of the workpiece 101 is restricted, so that the workpiece 101 is fixed.

[0024] The first plate body 211 is provided with a first through hole, and the first through hole corresponds to the position of the opening 112 when the support member 200 is fixed. A support rod 220 passes through the first through hole, and the support rod 220 passes through the opening 112 and extends into the slot body 111. The support rod 220 is placed at one end of the slot body 111 and is provided with a first limiter 221, and the support rod 220 is provided with a thread. The diameter of the first limiter 221 is greater than the width of the opening 112 so that the first limiter 221 can be locked with the opening 112. The first nut 230 is threadedly matched with the support rod 220. When the first nut 230 is rotated, the support rod 220 moves upward so that the first limiter 221 is locked with the opening 112, thereby fixing the first plate body 211 and the base 100. When the position of the support member 200 needs to be moved, the first nut 230 can be loosened.

[0025] The fixing member 300 further includes a cylinder 310, in which a telescopic cavity 311 is provided, in which a connecting rod 320 is inserted, and the connecting rod 320 is fixed to the fixing plate 370. A spring 312 is provided between the bottom of the telescopic cavity 311 and the connecting rod 320 to push the connecting rod 320 to move toward the outside of the telescopic cavity 311, and the cylinder 310 is fixed to the base 100. When fixing the workpiece 101, the fixing member 300 is set at the edge of the workpiece 101 so that the fixing plate 370 is located above the workpiece 101, and at the same time, the telescopic rod 330 passes through the opening 112, so that the second limit plate 340 is placed in the groove body 111. After it is in place, the telescopic rod 330 is rotated to move the telescopic rod 330 upward so that the second limit member 331 is locked with the opening 112, and then the telescopic rod 330 is continued to be rotated to move the fixing plate 370 downward. At this time, the fixing plate drives the connecting rod to move downward and compresses the spring 312, so that the workpiece 101 is clamped between the fixing plate 370 and the support member 200, which can prevent the workpiece 101 from deflecting.

[0026] A portion of the cylinder 310 is provided with a limit plate 340 extending outward, and a second through hole 341 is provided on the limit plate 340. When the fixing member 300 is installed, the second through hole 341 corresponds to the position of the opening 112. A fixing rod 350 passes through the second through hole 341, and the fixing rod 350 also passes through the opening 112 and extends into the slot body 111. The fixing rod 350 extends into the slot and is provided with a third limit member 351. The diameter of the third limit member 351 is greater than the width of the opening 112 so that the third limit member 351 can be locked with the opening. At the same time, a thread and a second nut 360 matched with the thread are provided on the fixing rod 350. When the second nut 360 is rotated, the fixing rod 350 moves upward so that the third limit member 351 is locked with the opening 112, and then when the second nut 360 is tightened, the limit plate 340 is fixed to the base 100, so that the fixing member 300 is fixed to the base 100. When the position of the fixing member 300 needs to be moved, the second nut 360 can be loosened.
