Technical Field

[0001] The utility model relates to the technical field of a locking mechanism for a sloping top workpiece, in particular to a locking mechanism for a sloping top workpiece. Background Art

[0002] When enterprises use machine tools to process square bevel workpieces, since the milling cutter can only move in the vertical direction, in order to ensure the processing quality, they can only use flat-nose pliers to clamp the square bevel workpiece, and use a calibrator to correct its inclination angle. This results in low clamping efficiency and difficulty in ensuring the angle of the square bevel workpiece, which in turn leads to low groove processing accuracy. At the same time, the manual operation time is long and the stability is poor, which is not conducive to batch processing. In view of this, we propose a locking mechanism for bevel workpieces.

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.

[0024] Example 1

[0025] See also Figure 1-Figure 4 As shown, the present embodiment provides a kind of inclined top type workpiece locking mechanism, including a base 1, the bottom surface of the base 1 is plugged with an angle block 2, the top inclined surface of the angle block 2 is slidably connected with a workpiece body 3, the side wall of the base 1 is provided with a balanced clamping mechanism 4, the balanced clamping mechanism 4 cooperates with the inner wall of the base 1 to clamp and fix the workpiece body 3, the side wall of the base 1 is provided with a storage groove 5, the inner wall of the storage groove 5 is slidably connected with a moving box 6, the bottom surface of the moving box 6 is hinged with a baffle 7, and one side of the baffle 7 is against the inner wall of the moving box 6, the inner wall of the moving box 6 limits the baffle 7 from flipping in the direction away from the base 1, and the other side of the baffle 7 is against the end of the workpiece body 3 located at a lower position. The baffle plate 7 blocks the workpiece body 3 from sliding downward along the top inclined surface of the angle block 2, so that the baffle plate 7 remains in a state perpendicular to the moving box 6. A displacement mechanism 8 is provided on one side of the moving box 6. The displacement mechanism 8 adjusts and locks the position of the moving box 6 in the storage slot 5. When the locking mechanism is in an idle state, the displacement mechanism 8 drives the moving box 6 to move a distance away from the base 1, and then the baffle plate 7 is flipped to the inside of the moving box 6, and then the displacement mechanism 8 drives the moving box 6 and the baffle plate 7 to move in the opposite direction, so that the moving box 6 and the baffle plate 7 can be completely stored in the storage slot 5, thereby reducing the space occupied by the locking mechanism and facilitating the storage of the locking mechanism.

[0026] In order to clamp and fix the workpiece whose side wall is non-planar, the structure of the balanced clamping mechanism 4 is refined. The balanced clamping mechanism 4 includes a mounting groove 41 opened on the side wall of the base 1, and two movable rods 42 are arranged inside the mounting groove 41. One end of the two movable rods 42 located in the base 1 is fixedly connected to a U-shaped clamping plate 45, and the other end of the movable rod 42 is fixedly connected to an end plate 43, and a spring 44 is fixedly connected between the end plate 43 and the inner wall of the mounting groove 41. The balanced clamping mechanism 4 also includes a bolt 46 threadedly connected to the side wall of the base 1, and one end of the bolt 46 located in the base 1 is against the side wall of the U-shaped clamping plate 45, so that the workpiece body 3 is placed at the angle After the top inclined surface of the degree block 2 is raised, the side of the workpiece body 3 opposite to the U-shaped clamp 45 is abutted against the inner wall of the base 1, and then the bolt 46 is turned. The part of the bolt 46 located in the base 1 is extended, so that the bolt 46 pushes the U-shaped clamp 45 to move in the direction close to the workpiece body 3. When one end of the U-shaped clamp 45 is abutted against one side of the workpiece body 3, the U-shaped clamp 45 drives the end plate 43 to deviate from the original axial direction of the movable rod 42 through the movable rod 42, and the spring 44 undergoes elastic deformation synchronously until both ends of the U-shaped clamp 45 are abutted against one side of the workpiece body 3, and the U-shaped clamp 45 cooperates with the inner wall of the base 1 to clamp and fix the workpiece body 3.

[0027] The position of the mobile box 6 in the storage slot 5 can be adjusted horizontally, and the position of the mobile box 6 is locked after the position is adjusted. The structure of the displacement mechanism 8 is refined. The displacement mechanism 8 includes a rack 81 fixedly connected to one side of the mobile box 6. One side of the base 1 is provided with an assembly slot connected to the storage slot 5. The inner wall of the assembly slot is rotatably connected to a gear 82, and the gear 82 is meshed with the rack 81. The top of the gear 82 is fixedly connected to a worm gear 83. The inner wall of the assembly slot is rotatably connected to a worm 84, and the worm 84 is meshed with the worm gear 83. When the worm 84 is turned, the worm gear 83 drives the worm gear 83 to rotate. The movable gear 82 rotates, and then through the meshing transmission of the gear 82 and the rack 81, the mobile box 6 is driven to slide horizontally along the inner wall of the storage groove 5. After the mobile box 6 is moved to the predetermined position, the self-locking property of the worm 84 and the worm wheel 83 makes it impossible for human power to push the mobile box 6 to move, thereby achieving the purpose of locking the position of the mobile box 6. A protrusion is fixedly connected to the bottom of the mobile box 6, and the side section of the storage groove 5 is an L-shaped structure. The protrusion is slidably connected to the inner wall of the storage groove 5. The protrusion further limits the moving path of the mobile box 6 in the storage groove 5, ensuring the stable meshing of the gear 82 and the rack 81.

[0028] In order to be able to quickly insert the angle block 2 into the base 1 from top to bottom and limit the horizontal movement of the angle block 2 in the base 1, a plurality of slots are opened in the bottom array of the base 1, and a plurality of pins are fixedly connected to the lower surface array of the angle block 2, and the plurality of pins are respectively abutted against the inner walls of the plurality of slots, and the lower surface of the base 1 is abutted against the bottom surface of the base 1. By inserting the plurality of pins into the plurality of slots respectively, the angle block 2 can be quickly inserted into the base 1, which effectively saves manual operation time and improves production efficiency.

[0029] In summary, the working principle of the present scheme is as follows: after the angle block 2 is plugged and fixed inside the base 1, the workpiece body 3 is placed on the top inclined surface of the angle block 2, and the side of the workpiece body 3 opposite to the U-shaped clamp 45 is abutted against the inner wall of the base 1, and the end of the workpiece body 3 located at the lower position is abutted against one side of the baffle 7, and the bolt 46 is turned until both ends of the U-shaped clamp 45 are abutted against one side of the workpiece body 3, and the U-shaped clamp 45 cooperates with the inner wall of the base 1 to clamp and fix the workpiece body 3, so that the locking mechanism can achieve the purpose of quickly clamping the workpiece. When the locking mechanism is in an idle state, the worm 84 is turned to make the moving box 6 move a distance away from the base 1, and then the baffle 7 is flipped to the inside of the moving box 6, and then the worm 84 is turned in the opposite direction to make the moving box 6 and the baffle 7 move in the opposite direction, and the moving box 6 and the baffle 7 are completely stored in the storage slot 5, thereby reducing the space occupied by the locking mechanism and facilitating the storage of the locking mechanism.
