[0001] The present invention relates to the field of machining, and particularly relates to an adjustable fixing device for machining. Background Art
[0002] When machining long-axis cylindrical parts, a fixing fixture is generally required to clamp and fix them. However, the existing fixing fixtures generally have the following defects. For example, it is not convenient to collect debris. At the same time, after the fixture clamps and fixes the product, it may move accidentally, resulting in the clamped product slipping out of the fixture and falling heavily on the workbench, thereby causing greater damage to the product and the equipment. Summary of the Invention
[0003] The purpose of the present invention is to provide an adjustable fixing device for machining.
[0004] The technical problems of the present invention are mainly solved by the following technical solutions:
[0005] An adjustable fixing device for machining, comprising a workbench:
[0006] A collecting hopper is arranged at the bottom of the workbench. A long-strip sliding opening is arranged on the side wall of the workbench directly above the opening of the collecting hopper. Slide seats are arranged on both sides inside the sliding opening. The slide seats are driven by electric push rods. A baffle extending outside the sliding opening is arranged at the top of the slide seat. A U-shaped plate located directly above the sliding opening is arranged on one side of the baffle. Two groups of U-shaped plates are arranged up and down错开, and the two groups of U-shaped plates seal the sliding opening. The top side wall of the U-shaped plate is a mesh structure. A vertical plate on the same side as the corresponding U-shaped plate is arranged on one side of the top of the baffle. A circular hole for the cylinder to pass through is opened on the vertical plate. A set of arc grooves are correspondingly arranged on the inner arc wall of the circular hole and the outer arc wall of the cylinder. A number of balls are evenly arranged in the two groups of arc grooves. A positioning mechanism is arranged on the cylinder on one side of the vertical plate. A screw tube is screwed on the cylinder on the other side of the vertical plate. A cylinder is sleeved outside one end of the screw tube. The positioning mechanism includes a toothed ring sleeved on the cylinder. A triangular locking seat is embedded in one of the tooth grooves of the toothed ring. A slide rod is arranged on the locking seat. A convex block through which the slide rod passes is arranged on the vertical plate. A spring is sleeved on the slide rod between the convex block and the locking seat.
[0007] Preferably, a pulley group is fixed to the bottom of the lower U-shaped plate through a vertical rod. A slide rail adapted to the pulley group is arranged in the collecting hopper, and the slide rail is fixed in the collecting hopper through a mounting rod.
[0008] Preferably, a handle is arranged on the outer wall of the cylinder. One end of the cylinder extends to the outside of the screw tube, and the cylinder is fixedly connected to the screw tube.
[0009] Preferably, a turntable is provided at one end of the cylinder on the same side as the toothed ring, and a rubber protective pad is provided at the other end of the cylinder.
[0010] Preferably, a polygonal through-hole for the sliding rod to pass through is provided on the bump, wherein the size of the sliding rod is adapted to the size of the through-hole, and a limiting block with a diameter larger than the through-hole is further provided at the end of the sliding rod.
[0011] Preferably, the width of the baffle is greater than the width of the sliding opening. A chute communicating with the outer space is provided on the top surface of the workbench directly below the baffle, and a slider located in the chute is provided at the bottom of the baffle.
[0012] The beneficial effects of the present invention are as follows: During processing in the present invention, the generated debris falls on the top surface of the U-shaped plate. The debris falls into the aggregate hopper through the aperture on the top side wall of the U-shaped plate for collection. When the two cylinders clamp and fix the rod during use, the screw tube can be rotated to rotate towards the rod, thereby driving the cylinder to move and sleeving on the end of the rod. In actual operation, if the diameter of the rod is not greater than the diameter of the cylinder, then even if the rod may slip between the two cylinders, it will fall on the inner bottom wall of the cylinder and be supported and fixed by it, preventing it from hitting the workbench. Since the height difference between the bottom end of the cylinder and the inner bottom end of the cylinder is small, the damage probability of the product can be maximally reduced, thereby protecting its safety.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the accompanying drawings.
[0019] An adjustable fixing device for machining includes a workbench 1:
[0020] A collecting hopper 2 is arranged at the bottom of the workbench 1. On the side wall of the workbench 1 directly above the opening of the collecting hopper 2, there is a long strip-shaped sliding opening 3. On both sides inside the sliding opening 3, there are sliding seats 4. The sliding seats 4 are driven by electric push rods 5. At the top of the sliding seat 4, there is a baffle 6 extending outside the sliding opening 3. On one side of the baffle 6, there is a U-shaped plate 7 located directly above the sliding opening 3. Two groups of U-shaped plates 7 are arranged up and down错开, and the two groups of U-shaped plates 7 seal the sliding opening 3. The top side wall of the U-shaped plate 7 is a mesh structure;
[0021] On one side of the top of the baffle 6, there is a vertical plate 8 on the same side as the corresponding U-shaped plate 7. A circular hole for a cylinder 9 to pass through is opened on the vertical plate 8. A set of arc-shaped grooves are correspondingly arranged on the inner arc wall of the circular hole and the outer arc wall of the cylinder 9. A number of ball bearings 10 are evenly arranged in the two groups of arc-shaped grooves. A positioning mechanism 11 is arranged on the cylinder 9 on one side of the vertical plate 8. On the cylinder 9 on the other side of the vertical plate 8, there is a screw tube 12 screwed, and a cylinder 13 is sleeved outside one end of the screw tube 12;
[0022] The positioning mechanism 11 includes a toothed ring 111 sleeved on the cylinder 9. In one set of tooth grooves of the toothed ring 111, a triangular locking seat 112 is embedded. A sliding rod 113 is arranged on the locking seat 112. On the vertical plate 8, there is a convex block 115 through which the sliding rod 113 passes, and a spring 114 is sleeved on the sliding rod 113 between the convex block 115 and the locking seat 112.
[0023] As Figure 1 shown, a pulley group 14 is fixed to the bottom of the lower U-shaped plate 7 through a vertical rod 15. A slide rail 16 adapted to the pulley group 14 is arranged in the collecting hopper 2, and the slide rail 16 is fixed in the collecting hopper 2 through a mounting rod 17. The mounting rod 17, the slide rail 16, the roller group 14 and the vertical rod 15 play a role in supporting and fixing the suspended U-shaped plate 7. When the electric push rod 5 drives the sliding seat 4 to drive the baffle 6 and the lower U-shaped plate 7 to move, it will drive the roller group 14 to slide on the slide rail 16 through the vertical rod 15 to prevent the above components from affecting the normal movement of the U-shaped plate 7.
[0024] As Figure 3 shown, a handle is arranged on the outer wall of the cylinder 13. One end of the cylinder 13 extends to the outside of the screw tube 12, and the cylinder 13 is fixedly connected to the screw tube 12.
[0025] In this embodiment, a turntable 18 is provided at one end of the cylinder 9 on the same side as the toothed ring 111, and a rubber protective pad is provided at the other end of the cylinder 9.
[0026] As Figure 3 shown, a polygonal through-hole for the slide bar 113 to pass through is provided on the bump 115. The size of the slide bar 113 is adapted to the size of the through-hole, and a limit block 116 with a diameter larger than the through-hole is further provided at the end of the slide bar 113.
[0027] In this embodiment, the width of the baffle 6 is greater than the width of the sliding opening 3. A chute 19 communicating with the outer space is provided on the top surface of the workbench 1 directly below the baffle 6, and a slider 20 located in the chute 19 is provided at the bottom of the baffle 6. When the baffle 6 is driven by an external force to move, it will drive the slider 20 to slide in the chute 19, so as to facilitate its movement while preventing the moving baffle 6 from moving forward and backward by the way of the chute 19 against the slider 20.
[0028] The working principle of the present invention: When in use, the long-axis bar is placed between the two cylinders 9. The electric push rod 5 drives the corresponding slide seat 4 to slide in the sliding opening 3, thereby reducing the distance between the two vertical plates 8 and the two cylinders 9, so that the displaced cylinders 9 clamp and fix the bar for processing;
[0029] When the slide seat 4 moves, it drives the baffle 6 to move, and the baffle 6 will drive the corresponding U-shaped plate 7 to move. The sliding opening 3 on the back of the vertical plate 8 is sealed by the baffle 6, and the sliding opening 3 between the two vertical plates 8 is sealed by the U-shaped plate 7 to prevent tools or parts from falling into the sliding opening 3. The debris generated during processing falls on the top surface of the U-shaped plate 7. The debris falls into the aggregate hopper 2 through the aperture on the top side wall of the U-shaped plate 7 for collection, or the debris on the top of the U-shaped plate 7 can also be dropped through its aperture by manual intervention;
[0030] During the above process, the spring 114 stretches and pushes the locking seat 112 to embed into one of the tooth grooves of the tooth ring 111, thereby locking and fixing the tooth ring 111 and the cylinder 9 to prevent the cylinder 9 from rotating in the circular hole and the arc groove on the ball 10, thereby fixing the rod clamped and fixed by the two groups of cylinders 9 to prevent the clamped and fixed rod from rotating. When it is necessary to process different end faces of the rod, it is only necessary to pull the slide bar 113 upwards and drive the locking seat 112 to move upwards. The rod 110 is pulled out from the tooth groove of the gear ring 111, and the spring 114 is compressed at the same time. Then, people can rotate the cylinder 9 to drive the arc groove on its outer arc wall to rotate on the ball 10, and then the rod clamped and fixed by the two groups of cylinders 9 can be rotated and adjusted, so as to facilitate the processing of different end faces. Finally, the slide bar 113 is released, and the locking seat 112 is pushed by the stretching force of the spring 114 to be embedded in the tooth groove of the gear ring 111 to lock and fix the gear ring 111, the cylinder 9 and the rod.
[0031] During use, after the two groups of cylinders 9 clamp and fix the rod, the screw 12 can be rotated to rotate it toward the rod, thereby driving the cylinder 13 to move and sleeve the end of the rod. In actual operation, the diameter of the rod is not greater than the diameter of the cylinder 9. Even if the rod may slip from between the two groups of cylinders 9, it will fall on the inner bottom wall of the cylinder 13 and be supported and fixed by it to prevent it from falling on the workbench 1. Since the height difference between the bottom end of the cylinder 9 and the inner bottom end of the cylinder 13 is small, the probability of damage to the product can be minimized to protect its safety. When processing the end of the rod, the screw 12 is rotated outward to drive the cylinder 13 to slide out from the end of the rod for processing.
[0032] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
