[0017] In order to solve the above technical problems, Figure 1-3 As shown, the utility model designs an ultrasonic knife tooling fixture, including a base plate 1, a supporting block 2, a first pressure block 3, a second pressure block 4, a third pressure block 5, a lifting drive mechanism 6, and a limiting pressing assembly. Two groups of lifting drive mechanisms 6 are provided on the left side of the base plate 1 and are connected to the first pressure block 3, two groups of lifting drive mechanisms 6 are provided in the middle of the base plate 1 and are connected to the second pressure block 4, and one group of lifting drive mechanisms 6 is provided on the right side of the base plate 1 and is connected to the third pressure block 5. The two first pressure blocks 3 are used to press the head of the ultrasonic knife rod 7, the two second pressure blocks 4 are used to press the middle part of the ultrasonic knife rod 7, and the third pressure block 5 is used to press the tail of the ultrasonic knife rod 7. By combining the three groups of lifting drive mechanisms 6 with the corresponding pressure blocks, precise pressing of the three parts of the ultrasonic knife rod 7 is achieved, which effectively improves the clamping stability of the fixture, avoids the displacement of the ultrasonic knife rod 7 during processing, and ensures processing accuracy.

[0018] A V-shaped limiting groove is provided on the top of each support block 2, and the V-shaped limiting grooves of each support block 2 overlap with each other. The support block 2 is used to support the ultrasonic knife rod 7 through the V-shaped limiting groove. The V-shaped groove can conveniently place and fix cylindrical workpieces. The operation is simple and fast, and the clamping time is reduced. The design of the limiting and clamping assembly enables the support block 2 to be accurately limited. Combined with the use of the V-shaped limiting groove, the accurate positioning of the ultrasonic knife rod 7 during the processing is ensured, and the processing error caused by inaccurate limiting is prevented.

[0019] A card slot is also provided on the leftmost support block 2, in which a positioning block 8 is fixed. A spherical positioning protrusion 9 is provided at one end of the positioning block 8, and the spherical positioning protrusion 9 is adapted to the inner hole of the sleeve at the head of the ultrasonic knife rod 7. A limiting plate 10 and a baffle 11 are also provided in sequence on the rightmost side of the base plate 1. The tail rod body of the ultrasonic knife rod 7 passes through the positioning hole of the limiting plate 10 and contacts the surface of the baffle 11. The spherical positioning protrusion is adapted to the inner hole of the sleeve at the head of the ultrasonic knife rod 7, providing highly precise positioning to ensure that the position of the knife rod in the fixture is accurate. Through the design of the limiting plate 10 and the baffle 11, the knife rod is more stable during the processing, reducing the potential risks caused by the movement of the knife rod.

The lifting drive mechanism 6 adopts a rotary downward pressure cylinder, which has a simple structure, convenient operation, and is easy to realize automatic control, which reduces the complexity of manual operation and improves work efficiency.

[0021] The cam 12 is fixed to the bottom plate 1 by a double bolt, and the double bolt fixing method of the cam 12 and the support block 13 enhances the stability and reliability of the entire cam 12. The cam 12 is fixed to the bottom plate 1 by a single bolt, and the side opposite to the cam 12 is a plane, and the support block 2 is engaged between the cam 14 and the fixed block 12. The other side of the cam 12 is provided with a downward pressure guide slope, and the support block 13 is provided with a supporting slope adapted to the downward pressure guide slope. The design of the downward pressure guide slope and the supporting slope enables the pressing block to smoothly perform the downward pressure action and push the cam 14 to press the support block 2 from one side, and the positioning of the support block 2 is more stable.

[0022] It is further preferred in this embodiment that a connecting plate 15 is installed at the front end of the third pressure block 5, and two forward-protruding pressure columns 16 are provided on both sides of the connecting plate 15, so that the clamping is more uniform, which can reduce the damage to the tool rod caused by excessive local pressure, and extend the service life of the tool rod.
