Abstract
The utility model discloses a tooling used in the drilling of connecting holes of bearing covers. The tooling comprises a bottom plate, and is characterized in that two sides of the bottom plate are provided with supporting bases, a drilling device with a hollow square structure is arranged between the supporting bases, and two ends of the drilling device are connected with the supporting bases on two sides of the drilling device through rotating shafts; the drilling device mainly comprises an upper drilling plate, a lower drilling plate, and connecting plates on two sides of the drilling device, and two through circular holes are formed in each of the upper drilling plate and the lower drilling plate; two threaded holes are formed between the two circular holes in the upper drilling plate, and bolts pass through the threaded holes; and pin shaft holes are formed in corresponding positions on the supporting bases and the connecting plates in the drilling device, and pin shafts are inserted into the pin shaft holes. Upper half parts of connecting holes of a bearing cover can be drilled by vertically placing the bearing cover in the drilling device with the hollow square structure and making the upper drilling plate upward; and the other half parts of the connecting holes of the bearing cover can be drilled by rotating the hollow square drilling device 180 degrees.
Description
Technical field
The utility model relates to a kind of frock, particularly a kind of brill bearing cap connecting hole frock.
Background technology
Bearing cap still needs multiple working procedure to finish the operations such as a series of milling flat, boring, fraising after by casting, because bearing cap both sides and reducing gearbox mating part are realized bolt by the bolt hole that bolt passes its both sides, but because this connecting hole is that shoulder hole and the degree of depth are darker, time processing is inconvenient.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of brill bearing cap connecting hole frock, and is simple in structure, is easy to the processing of connecting hole.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of brill bearing cap connecting hole frock, comprise base plate, its innovative point is: described base plate both sides are provided with supporting seat, be provided with the drilling equipment of hollow structure between described supporting seat, described drilling equipment two ends are connected with the supporting seat of both sides by rotating shaft; Described drilling equipment mainly is comprised of the connecting plate of upper perforated plate and lower perforated plate and both sides, be provided with on described upper perforated plate and the lower perforated plate and connect two circular holes, two corresponding on described upper perforated plate and lower perforated plate circular holes are on the same straight line in vertical direction, and the height between described upper perforated plate and lower perforated plate is slightly larger than the height of bearing cap; Be provided with two screwed holes in the middle of two circular holes on the described upper perforated plate, passed bolt in the described screwed hole; The corresponding position all has pin shaft hole on the connecting plate in described supporting seat and the drilling equipment, is inserted with bearing pin in the described pin shaft hole.
The utility model has the advantage of: by bearing cap vertically being placed the drilling equipment of hollow structure, bolt in two screwed holes in the utilization on the perforated plate props up the bearing cap sweep, thereby realize the location of bearing cap, upper perforated plate can be finished the boring of bearing cap connecting hole the first half up, when needs bore connecting hole the latter half, only need the bearing pin of supporting seat both sides is extracted out, rotation hollow drilling equipment 180 degree, so that lower perforated plate up, thereby finish the boring of second half part of bearing cap connecting hole.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a kind of front view that bores bearing cap connecting hole frock of the utility model.
Fig. 2 is a kind of left view that bores bearing cap connecting hole frock of the utility model.
Fig. 3 is a kind of top view that bores bearing cap connecting hole frock of the utility model.
Fig. 4 is a kind of state diagram of boring when perforated plate uses up on the bearing cap connecting hole frock of the utility model.
Fig. 5 is a kind of state diagram of boring when perforated plate uses down under the bearing cap connecting hole frock of the utility model.
The specific embodiment
Fig. 1, Fig. 2 and a kind of brill bearing cap connecting hole frock shown in Figure 3 comprise base plate 1, and base plate 1 both sides are provided with supporting seat 2,2 drilling equipments that are provided with the hollow structure of supporting seat, and the drilling equipment two ends are connected with the supporting seat 2 of both sides by rotating shaft 3.
Drilling equipment mainly is comprised of the connecting plate 6 of upper perforated plate 4 and lower perforated plate 5 and both sides, be provided with on upper perforated plate 4 and the lower perforated plate 5 and connect two circular holes 7, two corresponding on upper perforated plate 4 and the lower perforated plate 5 circular holes 7 are on the same straight line in vertical direction, and the height of 5 of upper perforated plate 4 and lower perforated plates is slightly larger than the height of bearing cap.
Be provided with two screwed holes in the middle of two circular holes 7 on the upper perforated plate 4, passed bolt 8 in the screwed hole, in order to prop up the bearing cap sweep.The corresponding position all has pin shaft hole on the connecting plate 6 in supporting seat 2 and the drilling equipment, is inserted with bearing pin 9 in the pin shaft hole.
During specific works, as shown in Figure 4, bearing cap is vertically placed the drilling equipment of hollow structure, bolt 8 in two screwed holes in the utilization on the perforated plate 4 props up the bearing cap sweep, thereby realize the location of bearing cap, upper perforated plate 4 can be finished the boring of bearing cap connecting hole 10 the first half up; When needs bore connecting hole 10 the latter half, as shown in Figure 5, only need the bearing pin 9 of supporting seat 2 both sides is extracted out, rotation hollow drilling equipment 180 degree, so that perforated plate 5 then inserts bearing pin 9 in the pin shaft holes down, thereby finish the boring of second half part of bearing cap connecting hole up.
