Abstract
The utility model discloses a kind of gear box casing Boring fixture, comprise base and be arranged on the pressure head on base, base has through hole near the position of pore-forming, also comprise reinforcement clamping device, reinforcement clamping device is the first supporting rod arranged in a crossed manner and the second supporting rod, the middle part of the first supporting rod and the second supporting rod is installed with a rotating shaft, and the two ends of rotating shaft are connected in through hole, and the operating side of the first supporting rod and the second supporting rod is installed with adjusting bolt.The utility model clamps the reinforcement on pore-forming, focuses near pore-forming, can make what clamp the better effects if of location near pore-forming, like this when carrying out bore hole, prevent pore-forming from moving with boring cutter, improve the precision of bore hole.The adjusting bolt of reinforcement clamping device is arranged on outside base, handled easily.
Description
Technical field
The utility model belongs to the technical field of positioner.
Background technology
Bore hole is to forging, and cast out or the further processing of drilling bore hole, bore hole can expand aperture, improves precision, reduces surface roughness, can also correct the deflection of original axially bored line preferably.
When to gear box casing bore hole, first need to clamp housing, existing gear box casing Boring fixture is mostly it is considered that clamping to housing entirety, and when carrying out bore hole, boring cutter can carry out reaming on the basis of pore-forming, and stressed at this moment near pore-forming is maximum, as just housing integrally clamped, and emphasis does not clamp around bore hole, the precision of bore hole will certainly be affected.
The surrounding that the applicant observes the pore-forming place of gear box casing is equipped with reinforcement, even if carry out bore hole to pore-forming, also can not destroy reinforcement, and not use being clamped in gear box casing Boring of reinforcement part.
Utility model content
The utility model provides a kind of gear box casing Boring fixture, to solve in gear box casing Boring not to the problem that the reinforcement near pore-forming clamps.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:. a kind of gear box casing Boring fixture, comprise base and be arranged on the pressure head on base, base has through hole near the position of pore-forming, also comprise reinforcement clamping device, reinforcement clamping device is the first supporting rod arranged in a crossed manner and the second supporting rod, the middle part of the first supporting rod and the second supporting rod is installed with a rotating shaft, the two ends of rotating shaft are connected in through hole, and the operating side of the first supporting rod and the second supporting rod is installed with adjusting bolt.
The operating side of the first supporting rod and the second supporting rod refers to the one end be positioned at outside housing herein, and the bare terminal end of the first supporting rod and the second supporting rod refers to the one end being positioned at housing.The inner side of bare terminal end refers to the side contacted with reinforcement.
Unscrew adjusting bolt, the bare terminal end of the first supporting rod and the second supporting rod is opened, make the bare terminal end of the first supporting rod and the second supporting rod be positioned at the both sides of reinforcement, pressure head is used for housing entirety to compress, after housing compresses, then screw adjusting bolt, reinforcement place is clamped.
Compared with prior art, the utility model has the advantage of: the reinforcement on pore-forming is clamped, focus near pore-forming by what clamp, the better effects if of location near pore-forming can be made, like this when carrying out bore hole, preventing pore-forming from moving with boring cutter, improve the precision of bore hole.The adjusting bolt of reinforcement clamping device is arranged on outside base, handled easily.
Further, the inner side of the bare terminal end of the first supporting rod and the second supporting rod is provided with projection, because reinforcement is usually thinner, therefore when clamping reinforcement, distance between first supporting rod and the second supporting rod bare terminal end is usually less, easily inaccurate when being positioned by adjusting bolt.Therefore having added projection in the inner side of the bare terminal end of the first supporting rod and the second supporting rod, the distance between the first supporting rod and the second supporting rod bare terminal end increases, and adjusting bolt can be utilized to locate accurately.
Further, the inner side of projection is provided with rubber layer, prevents reinforcement from being pressed from both sides bad.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the structural representation of the utility model gear box casing Boring fixture embodiment.
Fig. 2 is the structural representation of the utility model gear box casing Boring fixture reinforcement clamp embodiment.
Detailed description of the invention
Reference numeral in Figure of description comprises: base 1, pressure head 2, first supporting rod 3, second supporting rod 4, rotating shaft 5, adjusting bolt 6, projection 7.
As shown in Figure 1, a kind of gear box casing Boring fixture in the present embodiment, comprise base 1, reinforcement clamping device and be arranged on base 1 by the pressure head moving up and down 2 of Driven by Hydraulic Cylinder.Base 1 has through hole near the position of pore-forming, and as shown in Figure 2, reinforcement clamping device is that the middle part of the first supporting rod 3 arranged in a crossed manner and the second supporting rod 4, first supporting rod 3 and the second supporting rod 4 is installed with a rotating shaft 5, and the two ends of rotating shaft 5 are connected in through hole.The operating side of the first supporting rod 3 and the second supporting rod 4 is installed with adjusting bolt 6, and the inner side of the bare terminal end of the first supporting rod 3 and the second supporting rod 4 is provided with projection 7, and the inner side of projection 7 is provided with rubber layer.
In use, adjusting bolt 6 unscrewed, the operating side of the first supporting rod 3 and the second supporting rod 4 is opened, the bare terminal end of the first supporting rod 3 and the second supporting rod 4 also can open simultaneously.The convex surface of housing is placed upward, and makes the bare terminal end of the first supporting rod 3 and the second supporting rod 4 be in the both sides of reinforcement.Housing compresses to pressing down by pressure head 2, after housing compresses, screw adjusting bolt 6 again, the operating side of the first supporting rod 3 and the second supporting rod 4 closes up, simultaneously the bare terminal end of the first supporting rod 3 and the second supporting rod 4 also can close up, and reinforcement place clamps by the projection 7 on the first supporting rod 3 and the second supporting rod 4.
Because reinforcement is usually thinner, therefore when clamping reinforcement, the distance between the first supporting rod 3 and the second supporting rod 4 bare terminal end is usually less, easily inaccurate when being positioned by adjusting bolt 6.Therefore having added projection 7 in the inner side of the bare terminal end of the first supporting rod 3 and the second supporting rod 4, the distance between the first supporting rod 3 and the second supporting rod 4 bare terminal end increases, and adjusting bolt 6 can be utilized to locate accurately.
For a person skilled in the art; under the prerequisite not departing from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
