Description
Technical field
The utility model relates to automobile production and makes the field, relates in particular to a kind of vacuum booster back casing sealing gland frock.
Background technology
Vacuum booster is the brake power assist unit in the brake system of car, be the critical component in the brake system of car, its inside has a middle part that the diaphragm of push rod is housed, and cavity is separated into two parts, a part communicates with atmosphere, and another part links to each other with engine air inlet tube by pipeline.During its work, suck the principle of air when utilizing engine operation, cause a side cavity of vacuum booster to form vacuum, this chamber will form pressure differential with respect to another chamber normal air, even this pressure differential is very little, but because the area of diaphragm is bigger, still can produces very big thrust and promote diaphragm to vacuum one lateral movement, utilize pressure differential to strengthen retrothrust.For example the patent No. is 201220371458.4 the disclosed vacuum booster of utility model patent, comprise procapsid and the back casing that is connected with procapsid, be fixed with the diaphragm that the chamber between procapsid and the back casing is separated into ante-chamber and back cavity between procapsid and the back casing, the back casing center is equipped with input and tries hard to recommend bar, input is tried hard to recommend bar and is provided with and tries hard to recommend the inner that control valve assembly between bar and the back casing and input try hard to recommend bar in input and be fixed with the air valve seat, the control valve assembly comprises control valve, be provided with the push rod return spring that makes input try hard to recommend the bar return between control valve and the back casing, input is tried hard to recommend fixedly the push rod pad on the bar, one end of push rod return spring acts on the control valve, and the other end of push rod return spring is conflicted on the push rod pad.
The back casing of vacuum booster need be installed sealing gland, and the particular location of this sealing gland plays the effect of sealing between back casing and valve body, is to stop atmosphere from the seal that the booster rear portion enters, and guarantees booster back cavity and atmospheric isolation.If poor sealing, the brake power-assisted will lose efficacy, and the personal safety meeting is encroached on, and phenomenons such as burn into damage can appear in the booster inner body simultaneously.When vacuum booster was installed, the postpone housing of back casing sealing gland, back casing sealing gland gripper shoe, back casing sealing gland stopper ring need being packed into usually played sealing function.And in the prior art, when installing, the back casing sealing gland normally finishes by hand, need into back casing and carry out craft and compress will be packed after back casing sealing gland, back casing sealing gland gripper shoe, the alignment of back casing sealing gland stopper ring, the one side inefficiency, can't satisfy the large-scale production demand, manual compressing takes time and effort on the other hand, needs a large amount of human costs.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly can be when the back casing sealing gland is installed automatically back casing sealing gland, back casing sealing gland gripper shoe, back casing sealing gland stopper ring be pressed on vacuum booster back casing sealing gland frock in the back casing.
For addressing the above problem, a kind of vacuum booster back casing sealing gland frock of the present utility model, it is characterized in that: comprise horizontally disposed base plate, fixedly be useful on the positioner of placing back casing on the base plate, also vertically be provided with riser on the base plate, the top of riser has been horizontally disposed with gusset piece, and vertical direction fixedly has cylinder on this gusset piece, the clutch end of cylinder fixedly has pressure head, and this pressure head is positioned at the vertical top of described positioner; Described positioner comprises the tubular support that is fixed on the base plate, and the inside of this support is inserted with stair-stepping first locating shaft, and described support upper end is equipped with positioning sleeve, and this positioning sleeve is positioned at the described first locating shaft top; The axis of described first locating shaft is provided with the hole, is inserted with stair-stepping second locating shaft in the hole.
Vacuum booster back casing sealing gland frock of the present utility model, in use, back casing is placed on the positioner positions, again back casing sealing gland gripper shoe, back casing sealing gland, back casing sealing gland stopper ring are put into back casing successively, startup cylinder drive pressure head moves down rapidly to be pounded on back casing, start cylinder and reset, pound repeatedly and hit, no longer come off until sealing gland.Vacuum booster back casing sealing gland frock of the present utility model, accurate positioning, error is little, saves human cost, and efficient stable, adapts to the demand of large-scale industrial production.
Description of drawings
Fig. 1 is the structural representation of the utility model vacuum booster back casing sealing gland frock.
Fig. 2 is back casing and sealing gland assembly structure schematic diagram.
The specific embodiment
In order to make those skilled in the art person understand technical solutions of the utility model better, the utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 1, a kind of vacuum booster back casing sealing gland frock of the present utility model, comprise horizontally disposed base plate 1, fixedly be useful on the positioner of placing back casing on the base plate 1, also vertically be provided with riser 2 on the base plate 1, the top of riser 2 has been horizontally disposed with gusset piece 3, and vertical direction fixedly has cylinder 4 on this gusset piece 3, the clutch end of cylinder 4 fixedly has pressure head 5, and this pressure head 5 is positioned at the vertical top of described positioner.
Described positioner comprises the tubular support 6 that is fixed on the base plate 1, and the inside of this support 6 is inserted with stair-stepping first locating shaft 7, and described support 6 upper ends are equipped with positioning sleeve 8, and this positioning sleeve 8 is positioned at described first locating shaft 7 tops; The axis of described first locating shaft 7 is provided with the hole, is inserted with stair-stepping second locating shaft 9 in the hole.
Vacuum booster back casing sealing gland frock of the present utility model, in use, as shown in Figure 2, back casing 10 is placed on the positioner positions, again back casing sealing gland gripper shoe 11, back casing sealing gland 12, back casing sealing gland stopper ring 13 are put into back casing successively, startup cylinder drive pressure head moves down rapidly to be pounded on back casing, starts cylinder and resets, pound repeatedly and hit, no longer come off until sealing gland.Vacuum booster back casing sealing gland frock of the present utility model, accurate positioning, error is little, saves human cost, and efficient stable, adapts to the demand of large-scale industrial production.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
