Abstract
The utility model discloses a device for drawing a crankshaft timing gear, which comprises a screw rod, a drawing sleeve and clamp blocks. One end of the screw rod adopts a hexagon head, threads are formed on the rod body of the screw rod, and the other end thereof adopts a conical surface and is matched with the crankshaft head inner cone hole surface; the drawing sleeve adopting a thin-walled hollow structure is the main piece, wherein one end of the drawing sleeve is conducted with the screw rod through internal threads, large slotted holes are formed in the middle of the drawing sleeve, the dimension of the other end of the drawing sleeve with two slotted holes formed thereon is slightly larger than that of the timing gear; the clamp block is treated through heat so as to be strong and durable; and when in use, the clamp blocks are respectively placed into the two small slotted holes at one end of the drawing sleeve, and are jointed with the timing gear. By adopting the drawing device of the crankshaft timing gears, the assembled timing gears can be effectively drawn out, the mass loss can be lowered, and the cost can be effectively saved.
Description
Technical field
The utility model relates to a kind of device of doing over again, and relates in particular to a kind of device of drawing timing gears.
Background technology
Crankshaft timing gear and bent axle adopt interference fit, can well guarantee assembly quality after assembling.If but weak point is exactly an intractable after the misloading, and misloading takes place in reality is produced in batches frequently.This device will guarantee intact the pulling out of timing gears behind the misloading, the loss of avoiding misloading to bring effectively; And simple to operate, reliable, the convenient use.
Summary of the invention
This reality has novel purpose to be to provide a kind of device of drawing timing gears, comprising: screw rod, pull out the cover and fixture block, described screw rod one end is a turret head, the body of rod is a screw thread, the other end is the conical surface, matches with bent axle head internal taper hole face; Pulling out cover and be main body, is hollow-core construction, an end internal thread and screw rod conducting, and there is heavy slotted eye the centre, and other end size is slightly larger than timing gears and two slotted eyes is arranged; That this device has is easy and simple to handle, it is reliable to use, and effectively reduces the advantage of assembling loss.
Technical solution of the present utility model is such, comprises screw rod, pulls out cover, fixture block, it is characterized in that screw rod is that screw-threaded engagement connects with pulling out cover, and fixture block is stuck in to pull out in the cover slotted eye and fits with described timing gears.
Screw rod one end is a turret head, and shaft is a screw thread, and the other end is that the scalene cone and the bent axle crown overlay and close.
Pull out cover for the thin-walled hollow, an end endoporus is a screw thread, cooperates with screw rod, pulls out cover other end grooved hole and places fixture block, has big slotted eye to remove weight in the middle of pulling out cover.
Fixture block is through Overheating Treatment, and is durable, puts into two slotted eyes that pull out cover one end during use respectively, fits with timing gears, simple in structure, uses reliable.
Description of drawings
Fig. 1 is the profile that device of the present utility model pulls out cover.
Profile when Fig. 2 is device drawing of the present utility model.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
Among Fig. 1-Fig. 2, screw rod (1), pull out cover (2), timing gears (3), fixture block (4), bent axle (5).
The specific embodiment
Further specify the device of the utility model drawing timing gears below in conjunction with accompanying drawing.
As shown in Figure 2, among the utility model embodiment, the device of these drawing timing gears comprises: screw rod (1) with pull out cover (2) spiral marking connection, the interior angled end-face of an end applying bent axle (5) head, other end turret head outside.Two fixture blocks (4) insert respectively in the slotted eye that pulls out cover (2) end face and with timing gears and fit away from that end of screw rod (1).
In the present embodiment, the described cover (2) that pulls out is the hollow and thin-walled structure, satisfies the intensity of use, when hardness requires, by big dowel hole weight reduction, conveniently uses;
Detailed process: the urgent screw rod turret head of air pressure gun, make screw rod (1) other end be close to the interior angled end-face of bent axle head (5) earlier, make fixture block (4) chucking timing gears (3) and pull out cover (2); Continue urgently, pull out cover (2) under the effect of screw rod (1) screw thread power, slowly be pulled out, break away from bent axle (5), finish drawing until timing gears (3) with fixture block (4), timing gears (3).
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
Claims (3)
1. the device of drawing timing gears comprises: screw rod, pull out cover, fixture block, (1) is that screw-threaded engagement connects with pulling out cover (2) to it is characterized in that screw rod, fixture block (4) is stuck in and pulls out in cover (2) slotted eye and described timing gears (3) applying.
2. according to the device of the described drawing timing gears of claim 1, it is characterized in that screw rod (1) one end is a turret head, shaft is a screw thread, and the other end is that the scalene cone and bent axle (5) crown overlay and close.
3. according to the device of the described drawing timing gears of claim 1, it is characterized in that pulling out cover (2) and be the thin-walled hollow, an end endoporus is a screw thread, cooperates with screw rod, pulls out cover (2) other end grooved hole and places fixture block (4), and pulling out cover (2) centre has big slotted eye to go heavily.
