Problems solved by technology

Since the placement accuracy of the oil hole drill is very high and difficult to operate, the error of the oil hole processed in this way is relatively large, and the reject rate is high
In addition, for different types of crankshafts, the oil hole angles, main shaft diameters and connecting rod diameters are different, which results in the use of different drilling jigs for different types of crankshafts. High, many fixture replacement times, low efficiency and other defects

Embodiment Construction

[0030] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0031] like figure 1 As shown, the angle-adjustable crankshaft oil hole drilling jig mainly includes a support base 1, a guide plate 2, a clamp body 3, an N-jaw chuck 4 (a four-jaw chuck is used in the embodiment), an adjusting screw rod 6, and an angle adjusting gear 10 And positioning mechanism 12. The clamping mechanism clamps and fixes the crankshaft 5 on the clamp body 3 . The clamping mechanism and the position adjustment mechanism are fixedly connected with screws 8, and the positioning mechanism and the support base are fixedly connected with fastening screws 11.

[0032] like figure 2As shown, the clamping mechanism includes a four-jaw chuck and a rotary handle 15 . The four-jaw chuck is a commonly used chuck and mainly includes a chuck body 14, a chuck through hole 13, a reinforcing rib 16 and jaws 17. When the rotary handle 15 is turne...

Abstract

The invention discloses an angle-adjustable crankshaft oil hole drilling clamp which comprises a clamping mechanism and an angle adjusting mechanism. The clamping mechanism comprises an N-claw chuck and a rotating handle. The N-claw chuck comprises clamping claws and a chuck body. The angle adjusting mechanism comprises a supporting base, an angle adjusting gear and a guiding plate. A base bolt hole is arranged on the supporting base, a gear bolt hole is arranged at the center of the angle adjusting gear, a guiding plate bolt hole is arranged on the guiding plate, and a fastening bolt penetrates through the guiding plate bolt hole, the gear bolt hole and the base bolt hole sequentially to fixedly connect the guiding plate and the angel adjusting gear with the supporting base. The angle adjusting gear drives the guiding plate to rotate on the supporting base, and the upper surface of the guiding plate is connected with the bottom of the chuck body. The crankshaft oil hole drilling clamp can machine oil holes with different angles without replacing clamps.

Description

technical field [0001] The invention relates to a jig, in particular to a jig used for drilling crankshaft oil holes. Background technique [0002] The crankshaft oil hole is generally fixed and placed, and the oil hole drill moves back and forth relative to the crankshaft to drill oil holes in different parts. Since the placement accuracy of the oil hole drill is very high and difficult to operate, the oil hole processed in this way has a large error and a high reject rate. In addition, for different types of crankshafts, the oil hole angles, main shaft diameters and connecting rod diameters are different, which results in the use of different drilling jigs for different types of crankshafts. High, many fixture replacement times, low efficiency and other defects. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a crankshaft oil hole drilling jig that can process oil holes at different angles without changing th...
