Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
As shown in Figure 3, blade plate body 1 is the metallic plate of strip, and blade plate body is provided with the installing hole 11 of five spaced sets, and installing hole is screwed hole.At the screwed hole screw thread being arranged in centre, the first swivel nut 2 is installed, as shown in Figure 8, Figure 9, the first swivel nut 2 is circular metalwork, is provided with screw hole 21 at the center of the first swivel nut, the outer wall of the first swivel nut is provided with external screw thread 5, forcing screw 41 is installed in screw hole.The second swivel nut 3 is provided with at the installing hole being arranged in high order end and low order end, as shown in Figure 6, Figure 7, second swivel nut is circular metalwork, universal ball 31 is provided with at the center of the second swivel nut, universal ball inner wall smooth is used for setting pressure multi-directional ball 6, the outer wall of the second swivel nut is provided with external screw thread 5, to facilitate the connection of the second swivel nut and installing hole.As shown in Figure 4, the upper and lower end face of pressure multi-directional ball 6 is parallel, and the side of pressure multi-directional ball is spherical, and in pressure multi-directional ball, be provided with the first through hole 61, is provided with forcing screw 41 in the first through hole.In installing hole between two often adjacent forcing screws, also screw thread is provided with the second swivel nut 3, is provided with locking multi-directional ball 7 in this second swivel nut, and as shown in Figure 5, the upper and lower end face of locking multi-directional ball is parallel, and the side of locking multi-directional ball is spherical.Be provided with the second through hole 71 at the center of locking multi-directional ball, lock-screw 42 is installed in the second through hole.
As shown in Figure 1, Figure 2, shown in Figure 10, on blade plate body, be provided with five installing holes like this, in the installing hole of centre, be provided with the first swivel nut, in the first swivel nut, forcing screw is installed.In remaining four installing hole, be provided with the second swivel nut, in second swivel nut at two ends, pressure multi-directional ball be installed, in pressure multi-directional ball, forcing screw be installed.In two the second swivel nuts of centre, locking multi-directional ball is installed, in locking multi-directional ball, lock-screw is installed.
When vertical angles is pressurizeed time, in the installing hole in the middle of blade plate body, be screwed into the first swivel nut, the first through hole on the first swivel nut do not have female thread, is then directly screwed into forcing screw.Note, forcing screw and blade plate body contacts place, not with being threaded, being only used to pressurization and not being used to fix.
When the restriction due to skeletal structure needs that forcing screw is angled to be screwed into, this just needs to apply gimbal structure device, the pressurization multi-directional ball that this device is wrapped up by two the second swivel nuts be screwed into from blade plate body installing hole and the second swivel nut forms, pressurization multi-directional ball can freely be rotated in the second swivel nut, thus ensure the demand of different angles, the first through-hole wall in pressurization multi-directional ball is smooth, is only used to bear pressure.
When the restriction due to skeletal structure needs that lock screw is angled to be screwed into, this just needs to apply another gimbal structure device, the locking multi-directional ball that this device is wrapped up by two the second swivel nuts be screwed into from blade plate body installing hole and the second swivel nut forms, locking multi-directional ball can freely be rotated in the second swivel nut, thus ensure the demand of different angles, the second through hole in locking multi-directional ball is with female thread, and be provided with chamfering in one end of the first through hole, chamfering position is also threaded and plays locking action with the threaded engagement of the top cap end of lock-screw.
Because the shape of bone varies with each individual, in order to make blade plate body and people's bone better fit, to special manufacturing process be carried out when making blade plate body:
A, data acquisition, gather the digital image data of skeleton;
B, modeling, set up blade plate threedimensional model, obtains the outline data of blade plate threedimensional model;
C, on set up threedimensional model modify (due to gather skeletal image time be carry out on the basis of the skeleton damaged affect collection, so the blade plate model set up like this and suitable blade plate model have certain deviation, this just needs our artificial modifying to correct position to the blade plate threedimensional model of foundation);
D, instruction transformation, the Machining Instruction of design numerically controlled processing equipment;
E, blade plate molding, numerically controlled processing equipment, according to Machining Instruction, utilizes rapid shaping technique to prepare blade plate;
F, blade plate clamp automatic punching tapping;
G, blade plate deburring sterilization.
