DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figures 1 to 4 , the utility model provides a technical solution:

[0020] A CNC tooling fixture comprises a supporting platform, a frame 1 which is installed above the supporting platform and can be raised and lowered, hydraulic cylinders 2 which are symmetrically installed on both sides of the frame 1, a movable shaft connected to the output end of the hydraulic cylinder 2, and a clamping plate 3 which is connected to the end of the movable shaft away from the hydraulic cylinder 2. The supporting platform consists of a bracket 5 and a support 4 which is hinged to the bracket. The frame 1 is installed above the bracket 5, and a sliding mechanism is fixedly provided on one side. The support 4 is installed below the clamping plate 3, and a support rod 6 is movably connected between the bottom and the sliding mechanism. A chip storage box 7 for recycling waste is placed below the support rod 6, and a baffle for placing the chip storage box 7 is fixedly provided between the brackets 5.

[0021] During operation, when clamping the workpiece that needs to be supported, the workpiece is placed on the support 4 of the support platform for support, and then the hydraulic cylinder 2 is used to drive the clamping plate 3 to move and clamp the workpiece. When the processing is completed, the workpiece is taken out, and then the sliding mechanism is used to make the support rod 6 drive the support 4 to rotate downward, so that the waste falling on the support 4 during processing can fall into the chip storage box 7 for centralized recovery. When it is necessary to clamp the suspended workpiece, the position of the frame 1 can be adjusted upward first, so that the clamping plate 3 is away from the support 4, and the suspended workpiece is clamped and fixed by driving the clamping plate 3 to move. At this time, the support 4 located under the workpiece, on the one hand, plays a protective role, which can prevent the workpiece from causing greater damage when it falls. On the other hand, the waste generated by processing will fall on the support 4 in a concentrated manner. Finally, the support 4 is driven to rotate downward and opened, and the waste is centralized and recovered through the chip storage box 7.

[0022] Slots are provided on the outside of the bracket 5 and the support 4, and an insertion rod 9 is provided between the slots, and a storage cavity 10 for placing and storing the insertion rod 9 is installed on one side of the bracket 5. When working, when the support 4 is unfolded, the two ends of the bracket 5 can be inserted into the slots respectively for support, thereby improving the stability of work.

[0023] The sliding mechanism includes a fixed seat 11 fixedly installed on the inner side of the bracket 5, and a movable shaft 13 is rotatably installed inside the fixed seat 11. One end of the movable shaft 13 passes through the fixed seat 11 and is provided with an adjusting knob on the outside, and a spiral groove is provided on the outer surface. A sliding rod 12 is slidably connected to the spiral groove. A sliding groove slidably connected to the sliding rod 12 is provided on one side of the fixed seat 11. Both ends of the support rod 6 are movably connected to one end of the sliding rod 12 away from the movable shaft 13 and the bottom of the support 4 respectively. The movable shaft 13 can be driven to rotate by rotating the adjusting knob, so that the spiral groove drives the sliding rod 12 to move, and the sliding rod 12 drives the support rod 6 to move, thereby driving the bracket 5 to rotate upward or downward, thereby changing the position of the bracket 5.

[0024] The chip storage box 7 is a rectangular structure with an upper opening, a sieve plate 14 is detachably installed at the middle end thereof, and a sealing door is installed on one side of the sieve plate 14, so that waste materials falling into the chip storage box 7 can be screened, and the setting of the sealing door facilitates the installation of the sieve plate 14.

[0025] The middle part of the side wall of the chip storage box 7 is symmetrically provided with recessed blocks 15 at the same position, and the screen plate 14 is inserted between the recessed blocks 15, so that the screen plate 14 is easy to replace and clean.

[0026] The bottom of the frame 1 extends into the bracket 5 and is slidably connected to the inner wall of the bracket 5, and a rack 8 is installed on the outside. A gear 16 is meshed on one side of the rack 8. A motor for driving the gear 16 to rotate is installed inside the frame 1. The motor drives the gear 16 to rotate, and with the cooperation of the rack 8, the frame 1 is driven to be raised and lowered, so that the fixture can clamp the workpieces in two processing modes, namely, the workpieces that need to be suspended or supported.
