Technical Field

[0001] This application relates to the technical field of part processing, and particularly to a flipping fixture for part processing. Background Art

[0002] When processing parts, a fixture is required to stably clamp the parts in advance and then perform related processing operations. Although the current fixtures have the functions of clamping and flipping, due to the different parts and specifications to be processed, the clamping blocks and chucks on the fixture need to be replaced in a timely manner. Before using the fixture, the parts are clamped. After being clamped stably, the parts are flipped by rotating the motor.

[0003] However, in the actual use process, due to the different parts and specifications to be processed, the clamping blocks and chucks on the fixture need to be replaced in a timely manner. When replacing, the screws need to be loosened for replacement, and after replacement, the screws need to be tightened. This is very time-consuming and laborious during the production process.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

Detailed Description of the Embodiment

[0019] The following is a further detailed description of the present application with reference to the attached Figures 1-3 to further illustrate the present application in detail.

[0020] An embodiment of the present application discloses a flipping fixture for machining parts. Refer to Figures 1-3, A flipping fixture for part processing, comprising a support frame 2. A clamping assembly 3 is rotatably installed on the support frame 2. The bottom of the support frame 2 is bolted with a sliding table 1. The sliding table 1 is sleeved on the guide rail above the processing table and can move along the X-axis direction, flexibly adjusting the positions of the support frame 2 and the clamping assembly 3. By arranging two support frames 2 on the workbench, the two ends of the workpiece can be clamped synchronously to ensure the stability of the workpiece flipping. The clamping assembly 3 includes a chuck 301 rotatably installed on the support frame 2. Four clamping members 304 that can move radially are installed on the chuck 301. The workpiece is fixedly clamped by the clamping members 304.

[0021] Referring to Figure 1 , the chuck 301 includes a connecting ring 3012 rotatably installed on the support frame 2. A housing 3011 is rollingly installed at one end of the connecting ring 3012. A cavity is installed on the housing 3011. Four T-shaped grooves are radially formed on the housing 3011. The four clamping members 304 are slidably installed in the T-shaped grooves. The T-shaped grooves are used to guide the clamping members 304, so that the clamping members 304 can smoothly move along the radial direction of the chuck 301.

[0022] Referring to Figure 1 , the clamping member 304 includes a T-shaped block 3041 installed in the T-shaped groove. A clamping plate 3042 is hinged to the T-shaped block 3041 through a damping rotating shaft. Anti-slip pads are arranged on the surfaces of the clamping plate 3042 and the T-shaped block 3041 to increase the friction between the clamping member 304 and the workpiece and prevent the workpiece from sliding.

[0023] Referring to Figure 2 , a rotating ring 302 is rotatably installed in the cavity. The rotating ring 302 and the T-shaped block 3041 are connected by a tooth groove structure for transmission. In this solution, the tooth groove structure is designed as follows: a planar thread is provided on one side of the rotating ring 302 close to the clamping member 304, and a tooth groove matching the planar thread is provided on the T-shaped block 3041. By rotating the rotating ring 302 to drive the T-shaped block 3041 to slide along the T-shaped groove, the position adjustment of the T-shaped block 3041 is realized. A number of teeth are installed on the side of the rotating ring 302 far from the clamping member 304, and the teeth are evenly distributed along the circumferential direction of the rotating ring 302.

[0024] Referring to Figure 3A driving rod 303 is rotatably installed in the shell 3011. The driving rod 303 includes a rotating rod 3031 rotatably installed in the cavity, and the driving rod 303 and the rotating ring 302 are transmitted through a tooth structure. In this solution, the tooth structure is designed as follows: a tooth groove used in conjunction with the teeth is provided on the rotating rod 3031, and the end of the rotating rod 3031 passes through the shell 3011 and is connected to a screw handle 3032. By screwing the screw handle 3032, the rotating rod 3031 is rotated, thereby driving the rotating ring 302 to rotate, driving the clamping member 304 to move along the circumferential direction, and radially clamping the workpiece.

[0025] Reference Figure 2 There is still a driving device 4 on the support frame 2. The driving device 4 is connected to the connecting ring 3012 through a transmission component. The transmission component is configured as a gear set 5. The gear set 5 includes an outer gear ring 501 and a gear 502 that mesh with each other. The gear 502 is installed at the output end of the driving device 4, and the outer gear ring 501 is installed on the connecting ring 3012. The driving device 4 can use a motor reducer to drive the outer gear ring 501 and the gear 502 to rotate through the driving device 4, thereby driving the connecting ring 3012 and the housing 3011 to rotate, so that the clamping member 304 and the workpiece rotate to complete the flipping operation of the workpiece.

[0026] The implementation principle of a flip fixture for parts processing in the embodiment of the present application is:

[0027] When it is necessary to clamp a special-shaped workpiece or a rod, the clamping plate 3042 is flipped to the side away from the workpiece, and the rotating ring 302 is rotated by twisting the handle 3032 of the driving rod 303, thereby driving the T-shaped clamping block 3041 to move radially to achieve multi-point concentric clamping of the workpiece; when it is necessary to clamp a flat part, the clamping plate 3042 is flipped to the side close to the workpiece, and the plane symmetrical clamping of the workpiece is also achieved by twisting the handle 3032 of the driving rod 303. When it is necessary to flip the workpiece, the driving device 4 is started, and the gear 502 and the outer gear ring 501 are driven to rotate by the driving device 4, thereby driving the chuck 301 and the clamping member 304 to rotate, thereby achieving flipping of the workpiece.
