Description
Technical field
The utility model relates to a kind of fixture, specifically a kind of cam shaft gear tightens locking tooling.
Background technique
Process title: cam shaft gear assembly.
Process action: by the key on the keyway alignment cam axis on gear, then rotating gear makes it be directed at crankshaft
Timing indentation on gear, crankshaft toothed wheel are screwed into bolt locking cam shaft gear after engaging with cam shaft gear.
There are the problem of:
Electricity consumption rifle tightens cam shaft gear clamping screw, and cam shaft gear can be rotated and then.
Cam shaft gear clamping screw actual torque is less than electric rifle screw-down torque, and there are fictitious force squares.
Being put with a word bottle opener in two gears prevents cam shaft gear from rotating engagement place, takes a word to rise on the other hand on the other hand
By electric rifle, not only inconvenient there are also security risks.
Being risen with a word prevents gear from rotating, and can cause to damage to the flank of tooth, misoperation, which even will cause, collapses tooth.
Summary of the invention
The purpose of this utility model is to provide a kind of cam shaft gears to tighten locking tooling, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions:
A kind of cam shaft gear tightens locking tooling, including tooling ontology, locking pin, rotating handle, check lock lever, positioning
Pin, spacer pin, pilot hole and locking pin hole, tooling ontology are equipped with positioning pin, positioning pin at the L shape fallen, tooling ontology left side
It being fixedly connected with tooling ontology, tooling ontology bottom right side is equipped with check lock lever, and check lock lever is connect with tooling ontology by screw thread pair,
One end that check lock lever is located at tooling body exterior is equipped with rotating handle, and rotating handle is fixedly connected with check lock lever, and check lock lever is located at
One end of tooling body interior is conical surface shape, and tooling ontology right upper portion is provided with locking pin hole, locking pin hole axis and locking
Rod axis is vertical, engages and is inserted with locking pin in pin hole, and locking pin upper end is equipped with the groove cooperated with cam shaft gear and protrusion, card
Shotpin lower part be it is cylindric, locking pin lower part is provided with oblong pilot hole, and spacer pin passes through pilot hole and tooling ontology is fixed connects
It connects.
Further, the one end of the rotating handle far from check lock lever is hollow barrel-shaped.
Further, the rotating handle outer circle is equipped with anti-skidding annular knurl.
Compared with prior art, the utility model has the beneficial effects that
Cam shaft gear, which tightens locking tooling, 100% to realize when tightening wheel gear locking bolt that gear transfer can be eliminated
The fictitious force square formed after tightening makes screw-down torque be equal to the practical screw-down torque of bolt, reduces assembly cam shaft gear process
Security risk (gear rotation human body part is brought to be brought into weigh wounded), by the mounting hole and piece surface on engine, one
The support of one pin one of face guarantees that tooling can be stably placed on engine, prevents rundown process vibration from connect supporting point not with the flank of tooth
Touching and tooling falls off, improve the reliability that uses of tooling, reduce the labor intensity of operative employee, while can prevent with the anti-tooth of a word
Wheel rotation is damaged caused by gear, and the lift for engaging tooling is variable, and dismounting tooling is convenient, while can meet different gears
Demand is tightened, there is certain versatility.
Detailed description of the invention
Fig. 1 is the main view that a kind of cam shaft gear tightens locking tooling.
Fig. 2 is the left view that a kind of cam shaft gear tightens locking tooling.
Fig. 3 is the top view that a kind of cam shaft gear tightens locking tooling.
Fig. 4 is the locking engine cam gear structure schematic diagram that a kind of cam shaft gear tightens locking tooling.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Please refer to Fig. 1-4, a kind of cam shaft gear tightens locking tooling, including tooling ontology 3, locking pin 1, rotating handle
2, check lock lever 4, positioning pin 5, spacer pin 6, pilot hole 7 and locking pin hole 8, for tooling ontology 3 at the L shape fallen, tooling ontology 3 is left
Side is equipped with positioning pin 5, and positioning pin 5 is fixedly connected with tooling ontology 3, and 3 bottom right side of tooling ontology is equipped with check lock lever 4, check lock lever 4
It is connect with tooling ontology 3 by screw thread pair, check lock lever 4 is located at one end outside tooling ontology 3 equipped with rotating handle 2, rotates hand
Handle 2 is fixedly connected with check lock lever 4, and check lock lever 4 is located at one end inside tooling ontology 3 for conical surface shape, on 3 right side of tooling ontology
Portion is provided with locking pin hole 8, and locking 8 axis of pin hole is vertical with 4 axis of check lock lever, engages and is inserted with locking pin 1 in pin hole 8, engages pin 1
Upper end is equipped with the groove that cooperate with cam shaft gear and protrusion, locking 1 lower part of pin be it is cylindric, engage 1 lower part of pin be provided with it is oval
Shape pilot hole 7, spacer pin 6 pass through pilot hole 7 and are fixedly connected with tooling ontology 3.
Further, the one end of rotating handle 2 far from check lock lever 4 is hollow barrel-shaped.
Further, 2 outer circle of rotating handle is equipped with anti-skidding annular knurl.
The working principle of the utility model is:
The positioning pin 5 that cam shaft gear tightens locking tooling is inserted into the hole on engine, is made using the face on engine
For the support of tooling ontology 3, locking pin 1 blocks cam shaft gear, and rotation rotating handle 2 drives check lock lever 4 to rotate, so that check lock lever
The conical surface that 4 check lock levers 4 are located at one end inside tooling ontology 3 opens locking pin 1, and locking pin 1 holds out against cam shaft gear, then electric
Rifle tightens cam shaft gear clamping screw, and wheel gear locking bolt is to tighten clockwise, and the screwing force of bolt can make gear along up time
Needle transfer because gear transfer be it is unidirectional, then using locking pin 1 support withstand tooth form, cam shaft gear would not transfer.
The preferred embodiment of the patent is described in detail above, but this patent is not limited to above-mentioned embodiment party
Formula within the knowledge of one of ordinary skill in the art can also be under the premise of not departing from this patent objective
It makes a variety of changes.
