As shown in fig. 1, the ultrasonic spindle includes a cutter 101, an ultrasonic tool holder 102, a rotation shaft 103, a pull rod 104, an encoder gear 105 and a wireless receiving ring 100, the wireless receiving ring 100 is installed on the encoder gear 105, the encoder gear 105 is installed on the rotation shaft 103, the ultrasonic tool holder 102 and the rotation shaft 103 are connected and rotate together with the rotation shaft 103, the cutter 101 is fixedly connected to the ultrasonic tool holder 102, and other structures are not listed one by one. Of course, the wireless receiving ring 100 can be directly mounted on the rotating shaft 103 without the encoder gear 105.
As shown in fig. 2 and 3, the embodiment of the utility model provides a take wireless receiving ring of storage tank structure, including outer loop 1, diapire 2 and boss 3, outer loop 1 with diapire 2 is connected, outer loop 1 with diapire 2 can integrative punching press or cast molding, boss 3 sets up on the diapire 2, boss 3 is provided with central through-hole 7, central through-hole 7 runs through boss 3 with diapire 2, be provided with wire storage tank 6 on the boss 3.
In order to ensure that a wire can be connected to the coil in the wireless receiving ring, an annular accommodating space is provided between the boss 3 and the outer ring 1, and more importantly, the wire accommodating groove 6 communicates the central through hole 7 and the annular accommodating space. The annular receiving space is used for receiving ferrite (not shown), and the coil of the wireless receiving ring is wound in a containing groove in the ferrite.
The number of the wire accommodating grooves 6 is 2, and the wire accommodating grooves are symmetrically arranged to accommodate the positive wire and the negative wire respectively, so that the problem that the dynamic balance is poor when the spindle rotates at a high speed due to the arrangement of a single wire accommodating groove, and the processing stability of the ultrasonic knife handle 102 is affected can be avoided. In addition, during assembly, because the positive and negative leads are visible in the lead accommodating groove 6, the length of the leads can be cut off accurately and freely to meet the stroke requirement, and the assembly is obviously superior to the condition that the leads are arranged in the through holes in the push rods in a sealing mode and cannot be seen, and the leads in the pull rods can be broken by centrifugal force during high-speed rotation.
More importantly, an elastic pull-back structure (not shown) is arranged in the wire accommodating groove 6 and connected with the wire, so that the curled wire in the pull rod can be pulled back into the wire accommodating groove 6 (because of the stroke of the broach and the release broach, the wire cannot be returned into the wire accommodating groove 6 and is left in the through hole of the pull rod 104 when being stretched). The elasticity structure of pulling back can adopt the elastic component structure, and it can pull back the wire, consequently is not in the utility model discloses in enumerate, but be used for here to solve the problem of wire return the utility model discloses an innovation place.
Further, the top surface of the boss 3 is provided with a mounting hole 4, and the mounting hole 4 extends downward and penetrates the boss 3 and the bottom wall 2. More specifically, the wireless receiving ring is attached to the encoder gear 105 through the mounting hole 4.
