[0003] A Chinese patent with publication number CN219223673U discloses a milling machine for manufacturing and processing automobile inspection tools. By adding a clamping plate and a bidirectional screw, and adding an electric telescopic rod and a connecting rod, the two sets of clamping plates can be driven simultaneously to fix the automobile inspection tool through the cooperation of the clamping plate and the bidirectional screw.

An S-shaped member 4 is arranged on the upper side of the table 1, and a motor 5 is fixedly installed on the lower end surface of the table 1. A fixing mechanism is arranged on the lower side of the table 1, and the fixing mechanism comprises a stabilizing component 1 arranged on the outer side of the S-shaped member 4, and the stabilizing component 1 comprises a cross bar 16 fixedly installed on the end of the output shaft of the motor 5, and a slide groove 28 is provided on the upper end surface of the cross bar 16, and a slide groove 7 is provided on the upper end surface of the table 1, and a slider 19 is slidably connected inside the slide groove 8, and a transmission column 10 is rotatably connected to the upper end surface of the slider 9, and a slider 29 is slidably connected inside the slide groove 7, and the transmission column 10 is fixedly connected to the slider 29, and a clamping plate 11 is fixedly installed on the upper end of the transmission column 10.

[0027] First, place the S-shaped member 4 on the upper side of the table 1, and then start the motor 5 so that the output shaft of the motor 5 drives the cross bar 16 and the cross bar 28 to rotate synchronously, and the slider 19 rotatably connected to the lower end of the transmission column 10 is slidably connected to the slide groove 28 provided on the cross bar 6, and the transmission column 10 is fixedly connected to the slider 29 slidably connected inside the slide groove 7. Therefore, when the cross bar 16 deflects around the motor 5, the slide groove 17 and the slide groove 28 cooperate with each other to drive the splint 11 on the transmission column 10 to move toward the S-shaped member 4. The two groups of splints 11 correspond to the two concave arcs of the S-shaped member 4 respectively, and the two groups of splints 11 cooperate with each other to preliminarily fix the S-shaped member 4.

[0028] The fixing mechanism also includes a stabilizing component 2 arranged corresponding to the stabilizing component 1, and the stabilizing component 2 includes a slide rail 13 fixedly installed on the upper end surface of the table 1, and the upper end surface of the slide rail 13 is slidably connected with a transmission frame 12, one end of the transmission frame 12 is fixedly connected to the clamp 1 11, and the other end of the transmission frame 12 is fixedly installed with a clamp 2 14, and the clamp 2 14 is arranged on the other side of the S-shaped member 4.

[0029] When the splint 11 approaches the S-shaped part 4, the splint 2 14 will be carried by the transmission frame 12 to the outer arc edge of the S-shaped part 4 synchronously. The transmission frame 12 is slidably connected to the slide rail 13, and the slide rail 13 supports the transmission frame 12. Each group of splints 11 cooperates with a group of splints 2 14 to reinforce the auxiliary splints 11.

[0030] The fixing mechanism also includes an end fixing piece arranged inside the clamp plate 11, and the end fixing piece includes a gear ring 15 arranged on the lower side of the table 1, the gear ring 15 is slidably connected to the support leg 2, and a cross bar 28 is fixedly installed between the gear ring 15 and the cross bar 6.

[0031] A gear 16 is meshed inside the gear ring 15 , a shaft 17 is fixedly mounted on the upper end surface of the gear 16 , a cam 18 is provided at the end of the S-shaped member 4 , and the shaft 17 extends to the upper side of the table 1 and is fixedly connected to the cam 18 .

[0032] There are two groups of stabilizing components 1 and stabilizing components 2, which are arranged in a circumferentially dispersed manner corresponding to each other. There are two groups of end fixing members, which are respectively arranged at both ends of the S-shaped member 4.

[0033] The displacement of the second crossbar 28 will carry the gear ring 15 to rotate synchronously, and the gear ring 15 is meshed with the gear 16 on the rotating shaft 17, so the rotating shaft 17 will rotate synchronously, and the cam 18 fixedly mounted on the rotating shaft 17 will rotate synchronously, and the protrusions on the cam 18 will synchronously abut against the two ends of the S-shaped member 4 when the clamp plate 1 11 and the clamp plate 2 14 clamp and fix the S-shaped member 4, thereby strengthening the fixation of the S-shaped member 4 and improving the stability of the S-shaped member 4.

[0034] The fixing mechanism also includes an auxiliary extension piece arranged inside the first clamp plate 11, and the auxiliary extension piece includes a sliding cavity 27 opened inside the second slider 29. A storage cavity 24 is opened inside the first clamp plate 11, and a connecting cavity 19 is provided between the storage cavity 24 and the sliding cavity 27.

[0035] A force plate 20 is provided on the front side of the second slider 29, a piston plate 23 is slidably connected inside the sliding cavity 27, a transmission rod 21 is fixedly installed between the piston plate 23 and the force plate 20, and a spring 22 is fixedly installed between the force plate 20 and the second slider 29.

[0036] The two ends of the storage cavity 24 are slidably connected with extension rods 25 , and auxiliary plates 26 are fixedly mounted on the ends of the extension rods 25 .

[0037] When the slider 29 slides toward the S-shaped member 4 inside the slide groove 7, the force plate 20 at one end of the transmission rod 21 will first contact and abut against the inner wall of the slide groove 7, so that the piston plate 23 at the other end of the transmission rod 21 will be displaced inside the slide cavity 27, and then the gas inside the slide cavity 27 will be discharged into the storage cavity 24 through the connecting cavity 19, and then the two groups of extension rods 25 slidably connected inside the storage cavity 24 will be ejected, and the auxiliary plate 26 arranged at the end of the extension rod 25 will be extended synchronously with the extension rod 25, thereby expanding the contact area between the splint 11 and the S-shaped rod, thereby improving stability.

[0038] In practical applications, the existing equipment has poor fixing effect on workpieces, especially those with complex shapes such as S-shaped parts 4, which has an adverse effect on the quality of the final product. Due to its unique geometric shape, the S-shaped part 4 requires a more stable and precise fixing method to ensure that it will not be displaced or deformed during the processing, thereby ensuring the accuracy and quality of the product. Therefore, this solution has significantly improved the fixing effect of the S-shaped part 4 by setting up a special fixing mechanism and designing a specific fixing structure for the special S-shaped part 4. This solution creatively introduces a multi-layer fixing mechanism, which not only enhances the fixing stability, but also ensures that the S-shaped part 4 will not be displaced or deformed during the processing, thereby further improving the accuracy and quality of the product. This optimized design effectively meets the needs of high-precision manufacturing, while improving production efficiency and the qualified rate of finished products.

[0039] Method of use: First, place the S-shaped member 4 on the upper side of the table 1, then start the motor 5, so that the output shaft of the motor 5 drives the crossbar 1 6 and the crossbar 2 28 to rotate synchronously, the slider 1 9 rotatably connected to the lower end of the transmission column 10 is slidably connected to the slide groove 2 8 provided on the crossbar 1 6, and the transmission column 10 is fixedly connected to the slider 2 29 slidably connected inside the slide groove 1 7, so when the crossbar 1 6 deflects around the motor 5, the slide groove 1 7 and the slide groove 2 8 cooperate with each other to drive the clamping plate 1 11 on the transmission column 10 to move toward the S-shaped member 4, and the two groups of clamping plates 1 11 are respectively arranged corresponding to the two concave arcs of the S-shaped member 4, and the two groups of clamping plates 1 11 cooperate with each other to preliminarily fix the S-shaped member 4;

[0040] When the clamping plate 11 approaches the S-shaped member 4, the clamping plate 2 14 will be carried by the transmission frame 12 to the outer arc edge of the S-shaped member 4 simultaneously. The transmission frame 12 is slidably connected with the slide rail 13, and the slide rail 13 supports the transmission frame 12. Each group of clamping plates 11 cooperates with a group of clamping plates 2 14 to reinforce the auxiliary clamping plates 11.

[0041] Secondly, the displacement of the second crossbar 28 will carry the gear ring 15 to rotate synchronously, and the gear ring 15 is meshed with the gear 16 on the rotating shaft 17, so the rotating shaft 17 will rotate synchronously, and the cam 18 fixedly installed on the rotating shaft 17 will rotate synchronously. When the first clamping plate 11 and the second clamping plate 14 clamp the S-shaped member 4, the protrusions on the cam 18 will synchronously abut against the two ends of the S-shaped member 4, thereby strengthening the fixation of the S-shaped member 4 and improving the stability of the S-shaped member 4;

[0042] When the slider 29 slides toward the S-shaped member 4 inside the slide groove 7, the force plate 20 at one end of the transmission rod 21 will first contact and abut against the inner wall of the slide groove 7, so that the piston plate 23 at the other end of the transmission rod 21 will be displaced inside the slide cavity 27, and then the gas inside the slide cavity 27 will be discharged into the storage cavity 24 through the connecting cavity 19, and then the two groups of extension rods 25 slidably connected inside the storage cavity 24 will be ejected, and the auxiliary plate 26 arranged at the end of the extension rod 25 will be extended synchronously with the extension rod 25, thereby expanding the contact area between the splint 11 and the S-shaped rod, thereby improving stability.

[0043] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
