Detailed Description

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, a GD121A tool post correction tool includes a base plate 1, an upper plate 4 and a tool post 8.

As shown in fig. 1-7, the tool holder 8 is placed on the base plate 1, and the base plate 1 is connected to the upper plate 4 by bolts 5, so that the tool holder 8 is fixed and immovable. The base plate 1 is provided with a base plate step 2, the tool rest 8 positions the inner diameter of the tool rest 8 through a step side line 14 of the base plate step 2, an inner diameter side line 15 of the tool rest 8 is overlapped with the step side line 14 of the base plate step 2, the upper plate 4 covers the tool rest 8 from the upper side, and the upper plate 4, the tool rest 8 and the lower plate 1 are fixed through a bolt fixing hole 16 formed in the lower plate 1 through a bolt 5.

As shown in fig. 2, 7 and 8, the tool holder 8 is approximately cylindrical, and a plurality of shearing blades 9 uniformly extend from the surface of the tool holder. The bolt 10 acts on a bolt hole 17 of the holder 8 for fastening the insert. The base plate 1 is provided with a base plate inner groove 6, and the upper plate 4 is provided with an upper plate inner groove 7. Each shearing knife 9 corresponds to one chassis inner groove 6 and one upper disc inner groove 7, and the positions of the chassis inner groove 6 and the upper disc inner groove 7 correspond to each other;

in another embodiment, the number of shearing knives 9 is 17.

In another embodiment, the shearing blade 9 is rectangular.

In another embodiment, a rectangular shear knife is clamped between the inner recesses of the bottom plate and the upper plate, and the rectangular shear knife is translatable.

In another embodiment, both sides of the rectangular cutting blade move along the length of the inner grooves of the bottom plate and the upper plate respectively.

The circle where the outer circle 12 of the inner groove of the chassis 6 on the tooling chassis 1 and the outer circle 13 of the inner groove of the upper disc 7 on the tooling upper disc 4 are located are concentric. The position of the shearing knife 9 can be corrected when the blade edge of the shearing knife 9 is simultaneously contacted with the groove edges of the bottom disc inner groove 6 and the upper disc inner groove 7. The plurality of shearing knives 9 mounted on the knife rest 8 can be pushed and pulled respectively in the direction away from or close to the knife rest, the position can be adjusted by pulling outwards or pushing inwards, and the position of the shearing knives 9 can be corrected by making the blade edge of one shearing knife 9 contact the groove edge of the inner groove 6 in the chassis and the groove edge of the inner groove 7 in the upper disc at the same time.

The center of the upper disc 4 is provided with a bolt groove 11, the center of the lower disc 1 is provided with a bolt fixing hole 16, the bolt groove 11 in the center of the upper disc 4 and the bolt fixing hole 16 in the center of the lower disc 1 are concentric, the center of the tool rest is provided with a bolt fixing hole 3, a bolt 5 successively penetrates through the bolt groove 11 in the upper disc 4 and the bolt fixing hole 3 in the center of the tool rest and is fixedly connected with the lower disc 1 through the bolt fixing hole 16 (the bolt 5 is in threaded connection with the bolt fixing hole 16), and therefore the upper disc 4, the tool rest 8 and the lower disc 1 are fixedly connected.

By pulling the cutting blade 9 provided in the cutter holder 8 outward (i.e., in a direction away from the surface of the cutter holder), the blade edge of the cutting blade 9 is simultaneously brought into contact with the groove edge of the bottom plate inner groove 6 (refer to the outer edge of the bottom plate inner groove 6, i.e., the position pointed to by reference numeral 6 in fig. 3), i.e., the cutting blade is caused to translate leftward until the bottom plate inner groove left edge (fig. 3)), and the groove edge of the top plate inner groove 7 (refer to the outer edge of the top plate inner groove 7, i.e., the position pointed to by reference numeral 7 in fig. 3, and the cutting blade is also caused to translate leftward until the bottom plate inner groove left edge (fig. 3)), the positions of the bottom plate inner groove 6 and the top plate inner groove 7 correspond to each other, and correction of the cutter holder (the position of the cutting blade 9) can be achieved while ensuring that the blade edge of the cutting blade 9 is simultaneously brought into contact. Similarly, pushing inward translates the shear blade to the right (fig. 3). Finally, the bolt 10 is fastened, so that the correction of one shearing knife can be completed, all 17 shearing knives can be corrected in place by analogy (the correction in place means that the cutting positions of each shearing knife and the paper cutting wheel are the same), and the correction work of the whole knife rest is completed. The corrected cutter with the shearing cutter) frame is loaded into the equipment, and the alignment work of the whole cutter frame can be completed only by aligning the matching between one shearing cutter and the paper cutting wheel. The process groove is arranged beside the groove 6 in the base plate and used for reducing the contact surface of the blade and the base plate, and the process groove is also positioned on the base plate.

The utility model discloses the device has realized: the accurate quick adjustment of knife rest can reduce the experience requirement to professional technical staff adjustment knife rest effectively, the adjustment time in the maintenance has been saved simultaneously, about 2 hours are saved in the adjustment of every set of knife rest, and, the adjustment precision of knife rest has been improved, can guarantee through the frock that every shears the sword the same with the cutting position of cut paper wheel, cutting accuracy has been improved, cigarette quality has been guaranteed, reduce the wearing and tearing of shearing the sword, the life of shearing the blade has been prolonged, moreover, the steam generator is simple in structure and reliable, high durability and convenient use and dismantlement are accomodate, it is little to dismantle back frock occupation space, and the steam generator is easy to popularize and use.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
