Description

Technical Field

[0001] This utility model belongs to the field of fixture and tooling technology, specifically a fixture and tooling for irregularly shaped parts. Background Technology

[0002] Fixtures for irregularly shaped parts are process equipment used to clamp irregularly shaped workpieces. Through the rational design of positioning elements and clamping mechanisms, fixtures ensure that irregularly shaped parts are accurately and stably positioned during processing, preventing displacement and vibration. They can improve processing accuracy and efficiency, reduce labor intensity, and are widely used in fields such as machinery manufacturing and aerospace. They are important process equipment to ensure the processing quality of irregularly shaped parts and the smooth progress of production.

[0003] Currently, when existing fixtures for irregularly shaped parts clamp and fix the workpiece for processing, if it is necessary to flip the workpiece to adjust the processing angle, the operator still needs to manually flip the workpiece and then re-clamp and fix it. This is not only time-consuming and labor-intensive, but also inefficient. In addition, the waste generated during the processing of the workpiece also needs to be manually cleaned up, which greatly increases the workload of the operators. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a fixture for irregularly shaped parts, which solves the problem that when the existing fixtures for irregularly shaped parts are used to clamp and fix the workpiece for processing, if it is necessary to flip the workpiece to adjust the processing angle, the operator still needs to manually flip the workpiece and then re-clamp and fix it. This is not only time-consuming and labor-intensive, but also inefficient. In addition, the waste generated during the processing of the workpiece also needs to be manually cleaned up, which greatly increases the workload of the operator.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for irregularly shaped parts, including a worktable with a movable groove. Two bidirectional screws are mounted inside the movable groove via bearings. Two movable blocks are threaded onto the bidirectional screws. A movable plate is fixedly mounted on each movable block. The movable plate is slidably mounted within the movable groove. A protective box is fixedly mounted on the movable plate. A motor is fixedly mounted inside the protective box. A rotating shaft is rotatably connected to the output shaft of the motor. A turntable is mounted on one end of the rotating shaft that passes through the movable plate. A gripper is fixedly mounted on the turntable. Two connecting rods are fixedly mounted on the movable plate near the movable groove. A cleaning plate is fixedly mounted on each connecting rod and slidably mounted within the movable groove.

[0006] As a further embodiment of this utility model: a grooved wheel is installed at one end of the bidirectional screw that passes through the worktable, and a belt is sleeved on the grooved wheel.

[0007] As a further embodiment of this utility model: the grooved wheel is provided with a mounting box, and the mounting box is fixedly installed on the workbench.

[0008] As a further embodiment of this utility model: the mounting box is provided with a handle, one end of which passes through the mounting box and is connected to the grooved wheel, and the four corners of the workbench base are fixedly installed with support columns.

[0009] As a further embodiment of this utility model: a material discharge port is provided on the workbench, and two brackets are fixedly installed at the bottom of the workbench.

[0010] As a further embodiment of this utility model: a collection box is slidably mounted on the bracket, and a handle is fixedly mounted on the collection box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This irregular-shaped part fixture, equipped with a motor, a moving plate, bidirectional screws, and grippers, operates as follows: During operation, the operator rotates a handle, which in turn rotates a pulley. This pulley, in turn, rotates a belt, which in turn rotates two bidirectional screws synchronously. The rotation of these screws causes threaded moving blocks to move, which in turn move two moving plates and their mounted components towards each other until the grippers clamp and secure the workpiece. When the workpiece needs to be flipped to adjust its angle, the operator turns on the motor. The motor's output shaft rotates a rotating shaft, which in turn rotates a turntable. This rotation of the turntable, in turn, rotates the grippers fixed on it, causing the clamped workpiece to rotate synchronously. This allows for flipping and adjusting the machining angle without the need for manual workpiece flipping and re-clamping, saving time and effort and improving work efficiency.

[0013] 2. This irregular part fixture, through the setting of connecting rods, cleaning plates, handles, and collection boxes, allows for the following operation: when the operator rotates the bidirectional screw via the handle, the two moving plates move towards each other, thereby moving the two connecting rods. The movement of the connecting rods causes the cleaning plates fixedly installed on them to move. Since the cleaning plates are close to the moving grooves, the movement of the cleaning plates pushes the waste generated from the previous workpiece to move synchronously until the waste is pushed into the discharge port. The waste will then enter the collection box through the discharge port due to gravity, facilitating subsequent processing by the operator. This eliminates the need for manual waste handling and reduces the workload of the operator. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a fixture for irregularly shaped parts, including a workbench 1, a material discharge port 7 on the workbench 1, two brackets 5 fixedly installed at the bottom of the workbench 1, a collection box 6 slidably installed on the brackets 5, and a handle 10 fixedly installed on the collection box 6.

[0021] The workbench 1 has a movable groove 2. Inside the movable groove 2, two bidirectional screws 15 are installed through bearings. One end of the bidirectional screws 15 that passes through the workbench 1 is fitted with a grooved wheel 12, and a belt 13 is sleeved on the grooved wheel 12.

[0022] The grooved wheel 12 is provided with a mounting box 9, which is fixedly installed on the workbench 1. Because of the mounting box 9, dust and impurities can be prevented from getting on the surface of the grooved wheel 12 and the belt 13, thus avoiding affecting the work and improving the stability of the work.

[0023] The mounting box 9 is equipped with a handle 11. One end of the handle 11 passes through the mounting box 9 and is connected to the grooved wheel 12. Support columns 4 are fixedly installed at the four corners of the base of the workbench 1. Because of the handle 11, the grooved wheel 12 can be rotated through the handle 11. The grooved wheel 12 drives the belt 13 to rotate. The rotation of the belt 13 drives the two bidirectional screws 15 to rotate synchronously. The rotation of the two bidirectional screws 15 causes the moving block 14 connected to it to move. The movement of the moving block 14 drives the two moving plates 3 and the components installed on them to move towards each other until the gripper 21 clamps and fixes the workpiece. This can prevent the workpiece from loosening and shifting during processing, and at the same time facilitates the replacement of the workpiece.

[0024] Two moving blocks 14 are threadedly connected to the bidirectional screw 15. A moving plate 3 is fixedly installed on the moving block 14. The moving plate 3 is slidably installed in the moving groove 2. A protective box 8 is fixedly installed on the moving plate 3. A motor 16 is fixedly installed inside the protective box 8. Because of the motor 16, the output shaft of the motor 16 drives the rotating shaft 19 to rotate. The rotating shaft 19 drives the turntable 20 to rotate. The rotation of the turntable 20 drives the gripper 21 fixedly installed on it to rotate. The rotation of the gripper 21 drives the workpiece that is clamped and fixed to rotate synchronously, thereby flipping and adjusting the processing angle. There is no need for the operator to manually flip the workpiece and then re-clamp and fix it, which saves time and effort and improves work efficiency.

[0025] A rotating shaft 19 is rotatably connected to the output shaft of motor 16. A turntable 20 is installed at one end of the rotating shaft 19 that passes through the moving plate 3. A gripper 21 is fixedly installed on the turntable 20. Two connecting rods 18 are fixedly installed on the moving plate 3 near the moving groove 2. A cleaning plate 17 is fixedly installed on the connecting rods 18. Because of the cleaning plate 17, the moving plate 3 can move the cleaning plate 17, thereby pushing the waste generated by the previous workpiece to move synchronously until the waste is pushed into the discharge port 7. The waste will enter the collection box 6 through the discharge port 7 due to gravity. There is no need for the staff to manually handle the waste, which reduces the workload of the staff.

[0026] The cleaning plate 17 is slidably installed in the moving slot 2.

[0027] The working principle of this utility model is as follows: When working, the operator turns the handle 11, which drives the grooved wheel 12 to rotate. The grooved wheel 12 drives the belt 13 to rotate, which in turn drives the two bidirectional screws 15 to rotate synchronously. The rotation of the two bidirectional screws 15 causes the moving block 14 connected to them to move. The movement of the moving block 14 drives the two moving plates 3 and the components installed on them to move towards each other until the gripper 21 clamps and fixes the workpiece. When the workpiece needs to be flipped to adjust the angle, the operator turns on the motor 16. The output shaft of the motor 16 drives the rotating shaft 19 to rotate. The rotating shaft 19 drives the turntable 20 to rotate. The rotation of the turntable 20 drives the gripper 21 fixed on it to rotate. The rotation of the gripper 21 drives the workpiece clamped and fixed to rotate synchronously, thereby flipping and adjusting the processing angle.

[0028] When the operator drives the bidirectional screw 15 to rotate via the handle 11, the two moving plates 3 move toward each other, thereby driving the two connecting rods 18 to move. The movement of the connecting rods 18 drives the cleaning plate 17 fixedly installed on them to move. Since the cleaning plate 17 is close to the moving groove 2, the movement of the cleaning plate 17 will push the waste material generated by the previous workpiece to move synchronously until the waste material is pushed into the discharge port 7. The waste material will enter the collection box 6 through the discharge port 7 due to gravity, which is convenient for the operator to handle later.
