Abstract
The utility model relates to a pulley weights used for dismantling the bearing coat, which comprises a center adjusting block positioned in the middle, two telescopic adjusting arms which are symmetrically connected in the screw way in screw holes at the two sides of the center adjusting block, and two sections of working arms which are fixed on the outer ends of the two telescopic adjusting arms. The two telescopic adjusting arms and the two sections of working arms corresponding to the two telescopic adjusting arms are symmetrical. The vertical direction of the center adjusting block and the two telescopic adjusting arms is arranged with a screw hole which is internally arranged with a feed screw, the tail end of the feed screw is arranged with a gusset handle, the two sides of the center adjusting block is opposite to the screw hole which is connected in the screw way with the telescopic adjusting arms in the screw thread direction. The center adjusting block is arranged with two pairs of telescopic adjusting arms and working arms, according to demands, the center adjusting block is rotated positively or negatively to make the working arms flexed behind an axle sleeve, the position is aimed at, and the feed screw is arranged in the adjusting block and rotated by the gusset handle, and then the axle sleeve can be drawn out accurately and quickly, while the whole structure of the original assembly is not damaged, the working efficiency of the bearing maintain is improved in gemination.
Description
Technical field
The utility model relates to a kind of specific purpose tool, relates in particular to a kind of dismounting bearing outside chest expander.
Background technology
In the past, automobile was run into through regular meeting and to be renewed bearing and bad bearing is got the situation of not coming out in maintenance.The bearing of these cars all is embedded in the housing, can't draw with general chest expander.As: the clutch spindle guide bearing, very difficult during taking-up.Particularly when site construction, occur this type of fault at the scene and do not have specific purpose tool, sometimes get to come out, both lost time, spend fund again.So research and development one cover bearing overcoat chest expander change seems necessary.
The utility model content
At the problems referred to above, task of the present utility model provides a kind of dismounting bearing outside chest expander, facilitates the use a cover simple tools, removes bearing outside easily.
For finishing above-mentioned task, the technical solution of the utility model is: a kind of dismounting bearing outside chest expander, center adjustment piece in the middle of this chest expander comprises, two sections fixing respectively working arms of external end head of symmetry is spirally connected in the screw of center adjustment piece both sides two telescopic joint arms and two expansion plunger arms, two telescopic arms and two sections corresponding mutual left-right symmetry of working arm thereof, be provided with a screw at center adjustment piece and two expansion plunger arm vertical direction, the screw inside spin is equipped with a leading screw, the tail end of leading screw is provided with force application handle, and center adjustment piece both sides are opposite with the screw hand of spiral that expansion plunger arm is spirally connected.
Described working arm is the two section arched arms corresponding with the bearing outside radian, and the interior camber line mid point of arched arm and the external end head of telescopic adjustment wall are fixed together, and make expansion plunger arm be in the radial direction of arched arm.
The tail end of described leading screw is fixed with a contiguous block, is provided with an open-work vertical with leading screw in the contiguous block, and force application handle is slided to be installed in this open-work and is assembled together with leading screw.
Spiro rod section at two expansion plunger arms is respectively fitted with a locking nut.
The center adjustment piece has been installed two pairs of flexible arm and working arms adjusted, as required, forward or reverse center adjustment piece, can make working arm flexible behind axle sleeve, aligned position is loaded onto leading screw again in regulating block, use the force application handle rotational lead screw again, can be accurately, rapidly axle sleeve is pulled out, and do not damage the overall structure of former assembly, significantly improve bearing maintenance work efficient.This chest expander is reasonable in design, simple to operate, time saving and energy saving, stable performance, reduced maintenance cost.Under chest expander is arranged in pairs or groups the situation of a plurality of working arms, can draw the bearing outside of various models, and cost is low, easy to carry, be fit to vehicle and construct, go out etc. to use under the situation, have good popularizing application prospect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, is example with the clutch spindle guide bearing with removing the bearing outside chest expander, 6 rib blooms with 3cm*2cm*2cm are made center adjustment piece 1, vertically beat the open-work of diameter 0.8cm from the center, the positive silk of one end cover, the anti-silk of other end cover is laterally broken the open-work mantle fiber of diameter 1cm again and is put on leading screw 7 from the regulating block center.Do two same flexible arms 2 of adjusting respectively, the flexible arm 2 diameter 0.8cm that adjusts, the round steel of long 2cm, the silk of a headgear 1.5cm of one is joined a lock nut 5, diameter 0.8cm of other end welding, the circular arc type working arm 4 of arc length 3cm.In addition, with long 15cm, the round steel of diameter 1cm, front end 10cm place mantle fiber is made leading screw 7, and the round steel of a diameter 2cm of rear end welding is laterally beaten the hole of 1cm and made contiguous block 6, be provided with an open-work vertical with leading screw 7 in the contiguous block 6, sliding in the open-work installs force application handle 9 and is assembled together with leading screw 7.
During work, two working arms are put in the bearing outside, rotation regulating block screw makes its outside swelling, the locking lock nut, and rotating threaded shaft is pulled out bearing outside then.
