Detailed Description
For a better understanding and practice, the following detailed description of the embodiments is given in conjunction with the accompanying drawings; the examples are given solely for the purpose of illustration and are not intended to limit the scope of the invention.
As shown in fig. 1, 2, 3 and 4, the tool for quickly clamping and hoisting the automobile brake drum consists of a rotating member 1, an opening member 2, a cylindrical pin 3 and a split pin 4, wherein the cylindrical pin 3 and the split pin 4 are standard members and have low cost; the rotating part 1 is a 10mm thick steel plate welding assembly, a plurality of hanging holes 5 are machined in the left side plate of the rotating part 1, a hung part can be horizontally hung by selecting different hanging holes 5, a phi 17 first cylindrical pin hole 6 is machined in the middle, a top plate 7 is welded below the rotating part 1, the plate thickness is 2mm, when the brake drum is hung, a clamping effect is achieved, and a reaction force is formed by the weight of the brake drum, so that the brake drum is clamped; the right-most side is welded with the handrail 8 which is bent by phi 10 round steel, so that an operator can conveniently and quickly align to the clamped part of the brake drum, and the efficiency is improved; the split part 2 is a 10mm thick steel plate welding assembly, a phi 17 second cylindrical pin hole 9 is machined in the upper surface of the split part 2, two support blocks 10 are welded in the middle, a top plate 11 is welded on the lower left side, the plate thickness is 2mm, the strength is low, and the split part can deform along with the inner wall of the brake drum in the use process, so that the machining surface of the brake drum is not damaged; two end faces of the opening piece 2 are opposite, and a reaction force is formed when the brake drum is hung, so that the brake drum is clamped; installing a rotating piece 1 into the middle of an opening piece 2, aligning a first cylindrical pin hole 6 on the rotating piece 1 with a second cylindrical pin hole 9 on the opening piece 2, installing a cylindrical pin 3 in the middle, connecting the rotating piece 1 with the opening piece 2 through the cylindrical pin 3, installing a split pin 4 on the cylindrical pin 3, and locking the cylindrical pin 3 through the split pin 4; the rotating member 1 can be flexibly rotated.
The utility model discloses an instrument of tight handling car brake drum of quick clamp, in operation, the hoist is hung downthehole in the hanging on the rotating member, the handrail is held to the operator with the hand, place the instrument on the brake drum wall, then start the hoist, the rotating member receives ascending power and takes place the rotation, the roof can push up on the brake drum outer wall, power effect to certain degree left, the roof on the brake drum inner wall contacts the opening member, the opening member also follows thereupon rotatory certain angle, its opening lower extreme withstands behind the brake drum outer wall, form a reaction force system each other, thereby press from both sides tight hoist with the brake drum, if the brake drum is not level, can select different hanging hole, hoist up to the level.
Calculating a hanging hole selection method:
knowing that the brake drum radius is R, the mass is M0, the hanger mass is M1, if the hanger is hung in the positive center position, the left side mass is a North M0, the right side mass is a south M0+ M1, the right side is overweight, in order to hang the level, the hanger position needs to be moved to the right, and the brake drum offset part mass after moving to the right is M2, therefore, the following results can be obtained:
when the left and right masses are the same, the brake drum can be horizontally lifted, namely:
½M0+M2=½M0-M2+M1
to obtain: m2= as M1
Let the ratio of the offset to the mass of the brake drum be N
N=M2÷M0=½M1÷M0
Looking down the brake drum, the brake drum is a whole circle, the total angle is 360 degrees, and the angle occupied by the offset part is Y degrees
Y°=360°×N=360°×½M1÷M0
The circumference C =2 pi × R of the brake drum, and the arc length of Y ° is set to L:
L=Y°÷360°×C=½M1÷M0×2π×R
measuring a point of As L from the center line, horizontally projecting the point to the radius, vertically corresponding to the hanger, and finding a balance point.
The balance point can not reach a complete horizontal state, but can meet the production requirement.
