Description
Technical field
The utility model belongs to cylinder jacket processing technique field, more particularly to a kind of cylinder cover inner hole Knurling device.
Background technology
Cylinder jacket is the kernel component of engine work, except bearing high temperature, high pressure in the work of fuel engines
Adverse circumstances outside, vital effect is played in the work to engine.Interior surface of cylinder liner is due to by high-temperature high-pressure fuel gas
Effect and with the piston contact of high-speed motion and easily wear, if long-time low temperature operates, it will cause bad generation of burning
Carbon distribution, carbon distribution begin to extend from cylinder jacket top, cylinder jacket top is produced serious abrasive wear, are at present reduction cylinder jacket
Carbon distribution is worn, and generally use cylinder jacket and scrapes the mode that carbocyclic ring is used cooperatively, but both parts are being manufactured, assemble, made
It is extremely inconvenient during, also increase the cost of cylinder jacket component.
By setting twill groove to play a part of scraping carbocyclic ring on the inwall of cylinder set upper side, start so as to be effectively improved
The discharge of machine, but there is presently no the device for forming twill groove on cylinder liner internal wall with annular knurl technology mode.
The content of the invention
The purpose of the utility model is to solve above-mentioned problems of the prior art, and proposes a kind of cylinder cover inner hole
Knurling device, the annular knurl on the inwall of cylinder set upper side is realized so as to form twill groove to play a part of scraping carbocyclic ring, this reality
Adopted the technical scheme that with new to reach above-mentioned purpose：A kind of cylinder cover inner hole Knurling device, including hydraulic machine,
Motor is fixed with hydraulic machine, terminal pad is coaxially installed with machine shaft, swivel head is coaxially installed with terminal pad,
The elastic expansion-sleeve for fixing cylinder jacket is coaxially installed with swivel head, the left side for being used for fixing cylinder jacket is provided with swivel head
Detent mechanism, it is provided with terminal pad and is used to fix the right detent mechanism of cylinder jacket；Mobile mechanical arm is provided with hydraulic machine,
Mobile mechanical arm bottom is rotatably connected to knife bar by rolling bearing, and the central shaft of the knife bar and the central shaft of cylinder jacket are put down
OK, it is fixed with knurling tool in knife bar one end relative with swivel head.
Preferably, the left detent mechanism includes the circular column being fixed on swivel head, is provided with circular column and is used to block
The firmly first annular step of cylinder jacket left end, the right detent mechanism include the support arm being fixed in terminal pad, the support
The right-hand member of arm is provided with the second ring-shaped step for being used for blocking cylinder jacket right-hand member.
Had the beneficial effect that possessed by the utility model：Pass through matching somebody with somebody for left detent mechanism, elastic expansion-sleeve and right detent mechanism
Cooperation with reached to the circumferential and axial of cylinder jacket being accurately positioned and it is fixed, ensure that the coaxial of machine shaft and cylinder jacket
Degree requires, improves annular knurl quality processed；Detent mechanism and right detent mechanism also act the protective effect to cylinder jacket simultaneously, keep away
Exempt from the problem of to the damage of cylinder jacket inside and outside circle, deformation occur occurring " allow knife " phenomenon during annular knurl, it is achieved thereby that in gas
Annular knurl on the inwall of cylinder sleeve upper end is to play a part of scraping carbocyclic ring.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model includes hydraulic machine, motor is fixed with hydraulic machine, on machine shaft
Terminal pad 1 is coaxially installed with, swivel head 10 is coaxially installed with terminal pad 1, is coaxially installed with swivel head 10 for solid
Determine the elastic expansion-sleeve 9 of cylinder jacket 8, the left detent mechanism for being used for fixing cylinder jacket 8 is provided with swivel head 10, in terminal pad 1
Provided with for fixing 8 right detent mechanism of cylinder jacket；Mobile mechanical arm 4 is provided with hydraulic machine, is led in the bottom of mobile mechanical arm 4
Cross rolling bearing 5 and be rotatably connected to knife bar 6, the central shaft of the knife bar 6 is parallel with the central shaft of cylinder jacket 8, in knife bar 6 and rotation
The relative one end of rotary head 10 is fixed with knurling tool 7.
The left detent mechanism includes the circular column 2 being fixed on swivel head 10, is provided with circular column 2 and is used to block gas
The first annular step of the left end of cylinder sleeve 8, the right detent mechanism include the support arm 3 being fixed in terminal pad 1, the support arm
3 right-hand member is provided with the second ring-shaped step for being used for blocking the right-hand member of cylinder jacket 8.
The utility model when in use, will be arranged on terminal pad 1 after swivel head 10 and the hot charging of elastic expansion-sleeve 9, then will treat
Annular knurl cylinder jacket 8 is enclosed on elastic expansion-sleeve 9, circumferential to carrying out under the mating reaction of circular column 2, elastic expansion-sleeve 9 and support arm 3
Positioning with axial direction is fixed, and mobile mechanical arm 4 is moved up and down under hydraulic control, and knurling tool 7 is pressed on into the end of cylinder jacket 8
On the inwall in portion, and reach designed pressure value, finally start motor, machine shaft is taken offence with 30 revs/min of rotating speed band
Cylinder sleeve 8 rotates, so as to produce required annular knurl on the inwall of the end of cylinder jacket 8.
Reached by the mating reaction of left detent mechanism, elastic expansion-sleeve 9 and right detent mechanism to the circumference of cylinder jacket 8 and
Axial direction being accurately positioned and fixing, and ensure that machine shaft and the axiality requirement of cylinder jacket 8, improves annular knurl quality processed；Together
When detent mechanism and right detent mechanism also act protective effect to cylinder jacket 8, avoid occurring during annular knurl " allow knife "
There is the problem of to the damage of the inside and outside circle of cylinder jacket 8, deformation in phenomenon, it is achieved thereby that annular knurl on the inwall of cylinder set upper side is to rise
To the effect for scraping carbocyclic ring.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：
It can still modify to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacement, but these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the utility model technology
The spirit and scope of scheme.
