The silicon nitride push rod bar itself is in a fixed state when clamped, which affects the processing efficiency of the silicon nitride push rod bar. For this reason, we propose a forming device for processing ultra-long silicon nitride push rods. Utility Model Content

[0014] (1) A forming device for processing an extra-long silicon nitride push rod. In this scheme, the silicon nitride rod can first pass through the first group of clamping bins and the grinding wheel sleeve and the inside of the second group of clamping bins. At this time, the multiple groups of bolt mechanisms inside the two groups of clamping tables are rotated and adjusted to each other through the control handle, so that the movable clamping ball at the end of the bolt mechanism is pressed against the outer surface of the silicon nitride rod through the damping pad to clamp and limit the silicon nitride rod. When the motor is started, the motor can drive the control gear to engage and rotate through the driving gear. At the same time, the grinding wheel sleeve can be driven to grind the periphery of the silicon nitride rod accordingly. The end of the silicon nitride rod can be directly pushed by force, so that the silicon nitride rod slides under the deformation of the damping pad around the movable clamping ball and the clamping stability of the silicon nitride rod is ensured at the same time. When the silicon nitride rod moves, it can be directly ground through the grinding wheel sleeve, so that when the silicon nitride rod slides out of the grinding wheel sleeve as a whole, the feeding and grinding processing can be completed at the same time, thereby achieving the effect of improving the forming processing efficiency of the silicon nitride rod.

The internal thread of the screw groove 6 is connected with a bolt mechanism 7. A spherical groove 9 is opened at the end of the bolt mechanism 7. The spherical groove 9 is a three-quarter hollow spherical groove body. An active card ball 10 is arranged inside the spherical groove 9. The outer sleeve of the movable clamping ball 10 is provided with a damping pad 11 which fits with the inner wall of the spherical groove 9. The other end of the bolt mechanism 7 is equipped with a control handle 8 for controlling the bolt mechanism 7. The damping pad 11 itself has a deformation characteristic. When the bolt mechanism 7 is rotated by rotating the control handle 8, the movable clamping ball 10 at the end of the bolt mechanism 7 is in a mutually fitting and extruded state with the outer surface of the silicon nitride rod 5 through the damping pad 11.

[0029] In this scheme, the silicon nitride rod 5 can first pass through the first group of clamping bins 4 and the grinding wheel sleeve 15 as well as the inside of the second group of clamping bins 4. At this time, the multiple groups of bolt mechanisms 7 inside the two groups of clamping tables 2 are rotated and adjusted mutually through the control handle 8, so that the movable clamping ball 10 at the end of the bolt mechanism 7 is mutually pressed against the outer surface of the silicon nitride rod 5 through the damping pad 11, so that the silicon nitride rod 5 is clamped and limited. When the motor 17 is started, the motor 17 can drive the control gear 16 to engage and rotate through the driving gear 18, and at the same time, the grinding wheel sleeve 15 can be driven to grind the outer periphery of the silicon nitride rod 5 accordingly, and the end of the silicon nitride rod 5 can be directly pushed by force, so that the silicon nitride rod 5 slides under the deformation of the damping pad 11 outside the movable clamping ball 10 and at the same time ensures the clamping stability of the silicon nitride rod 5. When the silicon nitride rod 5 is moved, it can be directly ground by the grinding wheel sleeve 15, so that the feeding and grinding processing can be completed at the same time when the silicon nitride rod 5 slides out from the grinding wheel sleeve 15 as a whole, thereby improving the forming processing efficiency of the silicon nitride rod 5. When processing silicon nitride rods 5 of different diameters and thicknesses, the multiple groups of bolt mechanisms 7 inside the clamp table 2 can be rotated and adjusted to clamp and fix the silicon nitride rods 5 of different diameters, and the grinding assembly 23 can be directly slid and removed from the assembly slot 19 through the assembly clamp 20, and the grinding assembly 23 with the grinding wheel sleeve 15 of the appropriate size can be replaced and reinstalled, and fixed with the internal thread of the vertical plate 12 through the fixing bolt 22, so that the silicon nitride rods 5 of different diameters can be clamped and ground accordingly.
