Description

A kind of automobile brake drum provision for disengagement
Technical field
The utility model relates to auto repair facility equipment, is specifically related to a kind of automobile brake drum provision for disengagement.
Background technology
After running car a period of time, need regular or irregularly to check brake apparatus, keep in repair and safeguard, brake drum is as the vitals in brake apparatus, it is tight with on hub spindle, because working space is too small, in unloading process and difficulty, there is the multiple equipment about dismounting brake drum present stage, but it all also exists many deficiencies, common are following several situation: 1. equipment is not easy to adjustment, for different vehicles, cannot ensure axiality, larger active force can be produced in unloading process, even cause distortion; 2. gripper mechanism grips is unreasonable, adopts the point cantact parts such as clamping screws more, cause whole clamping device to act on a bit, have destructive wound for brake drum in existing equipment; 3. actuating unit design is unreasonable, cannot ensure axiality, cause brake rim or hub spindle to be damaged.
Summary of the invention
For above-mentioned Problems existing and deficiency, the utility model provides the automobile brake drum provision for disengagement that a kind of reasonable in design, axiality are good, be convenient to adjustment.
For solving the problem, the technical scheme taked is:
A kind of automobile brake drum provision for disengagement, comprise base, be arranged on the crane on base, be arranged on the gripper shoe on crane top, described gripper shoe is provided with riser, riser is fixed with dismounting hydraulic jack, the output of described dismounting hydraulic jack toward the outer side, and be fixed with push pedal at output, the rear portion of described dismounting hydraulic jack is fixed with a push rod, described push rod is arranged with brake drum hold-fast body, described brake drum hold-fast body comprises hollow cylindrical sleeve body, the axially uniform multiple tracks wedge-shaped impression be opened on sleeve body internal face, with the wedge shape compact heap be arranged in wedge-shaped impression, the inner surface of described wedge shape compact heap and axis being parallel, at least two pull bars are provided with between described sleeve body and push pedal, described riser offers the guide through hole of mating with pull bar.
Described crane comprises two ends respectively at gripper shoe and the hinged elevating lever of base and the raise-lower hydraulic oil cylinder that is arranged in the middle part of elevating lever and between base, and the described elevating lever between gripper shoe and base is at least two groups be arranged in parallel.
Friction line is provided with inside described wedge shape compact heap.
adopt technique scheme, acquired beneficial effect is:
The utility model is by the design to elevating mechanism, thus ensure that the levelness of whole working equipment, design for dismounting hydraulic jack, brake drum hold-fast body effectively can ensure the reasonability clamped, avoid causing damage to brake drum, simultaneously when dismantling, the axiality of whole process can be ensured, avoid that skew occurs and hub spindle is caused damage.Whole device structure is reasonable in design, good clamping effect, and axiality is good, effectively can improve structural behaviour and the Practical Performance of product.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
Fig. 2 be in Fig. 1 A-A to structural representation.
Fig. 3 is brake drum hold-fast body and the structural representation dismantling hydraulic jack.
Sequence number in figure: 1 be base plate, 2 be gripper shoe, 3 be riser, 4 for dismounting hydraulic jack, 5 be push pedal, 6 be push rod, 7 be sleeve body, 8 be wedge-shaped impression, 9 be wedge shape compact heap, 10 be pull bar, 11 be raise-lower hydraulic oil cylinder, 12 for elevating lever.
Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described, but the utility model is not limited to these embodiments.
See Fig. 1-Fig. 3, a kind of automobile brake drum provision for disengagement of the utility model, comprise base 1, the crane be arranged on base 1, be arranged on the gripper shoe 2 on crane top, described crane comprises two ends respectively at gripper shoe and the hinged elevating lever 12 of base and the raise-lower hydraulic oil cylinder 11 that is arranged in the middle part of elevating lever 12 and between base 1, and the described elevating lever 12 between gripper shoe 2 and base 1 is at least two groups be arranged in parallel.
Described gripper shoe 2 is provided with riser 3, riser 3 is fixed with dismounting hydraulic jack 4, the output of described dismounting hydraulic jack 4 toward the outer side, and be fixed with push pedal 5 at output, the rear portion of described dismounting hydraulic jack 4 is fixed with a push rod 6, described push rod 6 is arranged with brake drum hold-fast body, described brake drum hold-fast body comprises hollow cylindrical sleeve body 7, the axially uniform multiple tracks wedge-shaped impression 8 be opened on sleeve body 7 internal face, with the wedge shape compact heap 9 be arranged in wedge-shaped impression 8, the inner surface of described wedge shape compact heap 9 and axis being parallel, friction line is provided with inside described wedge shape compact heap 9.Be provided with at least two pull bars 10 between described sleeve body 7 and push pedal 5, described riser 3 offer the guide through hole of mating with pull bar 10.
The utility model is to the design of elevating mechanism, thus ensure that the levelness of whole working equipment, design for dismounting hydraulic jack, brake drum hold-fast body effectively can ensure the reasonability clamped, avoid causing damage to brake drum, simultaneously when dismantling, the axiality of whole process can be ensured, avoid that skew occurs and hub spindle is caused damage.Whole device structure is reasonable in design, good clamping effect, and axiality is good, effectively can improve structural behaviour and the Practical Performance of product.
