Description

Technical Field

[0001] This utility model relates to the field of workpiece forming and positioning fixture technology, specifically a workpiece forming and positioning fixture. Background Technology

[0002] Workpiece forming and positioning refers to the method of determining the accurate position and orientation of a workpiece within processing equipment or assembly fixtures during the manufacturing process. Its core lies in selecting appropriate datum surfaces or feature points based on product drawings or process requirements, and using positioning elements to restrict the workpiece's degrees of freedom in space, ensuring a unique and correct positional relationship relative to the cutting tool or other components. This process typically involves the selection of positioning datums, the rational distribution of positioning points, and necessary constraints, aiming to ensure the accuracy and consistency of the workpiece's dimensions and shape during subsequent processing or assembly. It is a key technological step in ensuring manufacturing precision and product interchangeability.

[0003] In fixture classification, rotary fixtures and contact clamping fixtures are two common types. Contact clamping fixtures can be further divided into general-purpose and specific types. For specific parts, while general-purpose fixtures are widely applicable, their clamping efficiency and positioning accuracy are usually difficult to match those of specific fixtures designed specifically for that part. Therefore, for specific workpieces requiring rapid production, the use of specific fixtures becomes an inevitable choice. However, these fixtures also face a common problem in application: their ability to remove impurities is often insufficient, and chips and other impurities generated during machining tend to accumulate, which may affect the stability of clamping and the final machining quality of the workpiece.

[0028] This mechanism is used for quick clamping of specific workpieces. It features a simple structure and high functionality. The quick clamping mechanism 3 includes a turntable 301, which is fixedly connected to the inside of one side of the shaping table 2. A gripper 302 is rotatably connected to the upper side of the turntable 301. A spring 303 is fixedly connected to the middle of the upper side of the shaping table 2, and the spring 303 is fixedly connected to the lower surface of the gripper 302. A guide pin 304 is fixedly connected to the inside of one side of the gripper 302, and the guide pin 304 is located inside the spring 303. The outer wall of pin 304 is rotatably connected to an adapter sleeve 305. The lower surface of the shaping table 2 is fixedly connected to a housing 306. A dual-axis motor 307 is fixedly connected inside the housing 306. A screw 308 is fixedly connected to the output end of the dual-axis motor 307. The screw 308 is threadedly connected to the inner wall of the adapter sleeve 305. A workpiece table 309 is fixedly connected to one side of the shaping table 2. A limit station 310 is fixedly connected to the side of the gripper 302 near the workpiece table 309. A chip removal groove 311 is opened inside the workpiece table 309.

[0029] Furthermore, the adapter sleeve 305 has a threaded groove inside that mates with the threaded screw 308.

[0030] Furthermore, a U-shaped opening is provided on the middle side of the limiting platform 310.

[0031] Furthermore, a limiting block structure for cooperating with the workpiece is fixedly connected to the upper side of the limiting stage 310.

[0032] Example 2:

[0033] This mechanism is used to provide auxiliary cleaning for the equipment. It addresses the limitations of traditional equipment in handling processing interference caused by debris. (See also...) Figure 1-5Furthermore, in conjunction with Embodiment 1, the cleaning auxiliary mechanism 4 includes a fan blade 401 and multiple chip collection covers 408. The fan blade 401 is fixedly connected to the lower output end of the dual-axis motor 307. A wind duct 402 is sleeved on the outside of the fan blade 401. The wind duct 402 is fixedly connected to the lower surface of the casing 306. A debris collection cylinder 403 is fixedly connected to the lower side of the wind duct 402. A debris removal cylinder 404 is threadedly connected to the lower side of the debris collection cylinder 403. A filter plate 405 is fixedly connected inside the wind duct 402. The filter plate 405 is located below the fan blade 401. A suction cylinder 406 is connected inside the wind duct 402. The suction cylinder 406 is located below the filter plate 405. A diverter 407 is connected to one side of the suction cylinder 406. The chip collection covers 408 are fixedly connected to the lower surface of the workpiece table 309. All chip collection covers 408 are connected to the chip discharge groove 311 and the diverter 407.

[0034] Furthermore, the upper side of the air duct 402 is provided with multiple through holes.

[0035] Furthermore, the lower side of fan blade 401 is configured as a negative pressure output terminal.

[0036] In actual operation, when this device is used, the user places the workpiece on the upper side of the workpiece table 309 and engages the upper protrusion of the workpiece table 309 with the workpiece. Then, the user can start the dual-axis motor 307. The output of the upper end of the dual-axis motor 307 drives the screw 308 to rotate. The screw 308 and the adapter sleeve 305 form a threaded engagement, causing the height of the guide pin 304 to change. This allows the limiting table 310 to quickly clamp and release the workpiece, avoiding the time loss caused by adjusting the positioning. At the same time, the output of the lower end of the dual-axis motor 307 drives the fan blade 401 to generate negative pressure. The negative pressure acts directly on the processing area through the chip collection cover 408, allowing the chips to be drawn into the air duct 402. Meanwhile, the filter plate 405 of the air duct 402 can block the debris, causing the debris to accumulate inside the debris removal cylinder 404. The user can unscrew the debris removal cylinder 404, making the device simple in structure and convenient to operate.
