Example three:
fig. 7-8, a cartilage slicing knife. The present embodiment is a structural improvement of the first embodiment.
The cutter guide block 40 which presses costal cartilage from the upper end is arranged in the material placing groove, the width K3 of the cutter guide block corresponds to the width K2 of the material placing groove, and the cutter guide block can be embedded into the material placing groove in a sliding fit mode. Bolt holes 47 are respectively arranged at two ends of the cutter guide block, the bolt holes 47 are stepped holes, and pressure regulating springs 46 are arranged in the bolt holes 47. The base plate is provided with screw holes 37 at positions corresponding to the bolt holes 47. Guide block bolts 45 are arranged at two ends of the cutter guide block, the guide block bolts 45 are screwed into the screw holes 37 of the base, and the cutter guide block is pressed on the costal cartilage through pressure regulating springs 46 by the guide block bolts.
The cutter guide block is provided with two blade guide grooves 41 corresponding to one blade 21, and the blade 21 is slidably fitted to the blade guide grooves and penetrates the blade guide grooves to cut costal cartilage.
The cutter guide block compacts the costal cartilage from the upper end through the elastic force of the pressure regulating spring, so that proper pressure can be obtained, the fixation and modification of the costal cartilage are further improved, and the costal cartilage is prevented from being loosened and deformed when being cut. The mode of compacting the costal cartilage with a relatively rigid force adopts the pressure regulating spring to obtain a stable costal cartilage fixing effect, can also avoid the costal cartilage from being deformed by overlarge compression, and ensures that the cut cartilage pieces are relatively regular. The blade guide groove of the cutter guide block can control the blade to accurately move along the cutting path, and the blade is prevented from generating horizontal displacement and deformation, so that the cutting quality is ensured.
This embodiment is because adopted the cutter guide block to lead the cutter, no longer need the cutter arbor with put the corresponding and sliding fit of size of silo.
Example four:
fig. 9, a cartilage slicing knife. This embodiment is a structural alternative to the first embodiment.
In the scheme of the first embodiment, the bottom of the material placing groove is a plane. In this embodiment, the bottom of the material-holding groove is a V-shaped groove 34, and the cutting empty groove is arranged in the middle of the V-shaped groove.
The V-shaped groove at the bottom of the material placing groove has a positioning effect on cylindrical materials, particularly cylindrical costal cartilage with a regular shape, the cylindrical costal cartilage can be conveniently placed in the material placing groove, and even if the cylindrical costal cartilage is kept at a proper position, the cutter guide block 40 presses the costal cartilage from the upper end, so that a stable cutting process can be realized. In this embodiment, the side positioning block 70 in the first embodiment can be eliminated, and the operation of cutting the cartilage is simplified.
If the costal cartilage needs to be further fixed, lateral positioning screws which press the costal cartilage can be arranged on the two sides of the material placing groove. In this embodiment, lateral positioning screws 36 pressing costal cartilage are disposed on both sides of the material placing groove, and the lateral positioning screws 36 replace the lateral positioning blocks 70.
Example five:
as shown in fig. 10 to 13, this embodiment is a structural replacement of the third embodiment.
In this embodiment, the cutter 20 is mounted on the cutter bar 50, the front end of the cutter bar is hinged to the bottom plate 60 through the rotating shaft 61 to form a guillotine structure, and the cutter bar drives the cutter to cut into the costal cartilage downwards.
The base 30 is provided with a material placing groove 34 for placing costal cartilage, the bottom of the material placing groove is a V-shaped groove, and the bottom of the material placing groove is provided with a cutting empty groove 32.
A cutter guide block 40 is arranged on the cutter bar. The width K1 of the cutter guide block corresponds to the width K2 of the material placing groove, and the cutter guide block can enter the material placing groove in a sliding fit manner and press costal cartilage from the upper end. The cutter guide block is provided with two blade guide grooves 41, each blade guide groove corresponds to one blade of the cutter, the blades are in sliding fit with the blade guide grooves, and the blades can penetrate through the blade guide grooves and extend out of the blade guide grooves to cut costal cartilage.
the cutter guide block is provided with two connecting rods 42, the cutter guide block is connected with the cutter bar through the connecting rods, a pressure spring 43 is arranged between the cutter guide block and the cutter bar, the cutter bar is provided with a connecting rod hole 51 which is a long hole, the connecting rod 42 is provided with threads, the connecting rod penetrates through the connecting rod hole, the end of the connecting rod is connected with the cutter bar through a nut 44, and the nut 44 is a check nut.
In the natural state, the cutting edge of the cutter is within the blade guide groove, as shown in fig. 13.
As shown in fig. 11, in order to further improve the fixing effect or adjust the position of costal cartilage, two lateral positioning screws 36 are arranged on each side of the two sides of the material placing groove.
During operation, the costal cartilage is placed in the material placing groove, so that the lower end of the costal cartilage is in good contact with the bottom surface of the material placing groove (namely, the contact surface is kept as large as possible), and for the costal cartilage with a regular shape, the material placing groove with the V-shaped groove on the bottom surface can have a good positioning effect. If the fixing effect is required to be further improved or the position of the costal cartilage is required to be adjusted, the costal cartilage can be further fixed at two ends through lateral positioning screws. Then the cutter bar is moved downwards, so that the cutter guide block enters the material placing groove and is contacted with costal cartilage. The cutter guide block is contacted with the costal cartilage through the elastic force action of the pressure spring, and the bottom surface of the cutter guide block can keep a better contact state with the costal cartilage. Because the cutting edge of the cutter is kept in the blade guide groove in a natural state, when the bottom surface of the cutter guide block is contacted with the costal cartilage, a distance exists between the cutting edge of the cutter and the costal cartilage. When the cutter bar drives the cutter to move downwards continuously, the cutter guide block is compacted on the costal cartilage by the elastic force generated by the contraction of the pressure spring. And then the cutting edge of the cutter continues to move downwards to extend out of the cutter guide block to cut the rib cartilage, and the cutting edge finally enters a cutting empty groove at the bottom of the material placing groove to finish the cutting of the cartilage sheet.
Compared with the three phases of the embodiment, in the embodiment, the cutter guide block can compact the costal cartilage when driven by the cutter bar to move downwards, the cutter guide block is not required to be compacted into the costal cartilage by special operation, the cutter bar is directly pressed downwards to complete the cutting operation, and the cutting operation process can be obviously simplified.
