Detailed Description
The utility model will be further explained with reference to the drawings.
Example 1: referring to fig. 1 to 7, the reverse pressing mechanism for rapidly clamping and loosening the automobile part comprises a base 1, wherein a horizontal through hole is formed in the base 1, a pressing screw rod 2 in sliding fit with the through hole is arranged in the through hole, a pressing nut 3 is arranged at one end of the pressing screw rod 2, the other end of the pressing screw rod is connected with a vertical pressing block 4, the top of the pressing block 4 is connected with the pressing screw rod 2, and the bottom of the pressing block is used for pressing the automobile part 6 on the base 1;
the automobile part 6 is provided with a horizontal positioning hole, a first pin hole 10 and a second pin hole 11 are respectively arranged at the positions, corresponding to the positioning hole, of the base 1 and the pressing plate, a positioning pin 5 is arranged on the base 1, the tail part of the positioning pin 5 sequentially penetrates through the first pin hole 10 and the positioning hole from one end far away from the pressing plate and then is inserted into the second pin hole 11, and the part, located in the second pin hole 11, of the tail part of the positioning pin 5 is an adjusting section;
a gasket 7 is sleeved on the compression screw rod 2 between the compression nut 3 and the base 1 in a penetrating manner, the gasket 7 is vertically arranged in an elliptical ring shape and comprises an upper part 8 and a lower part 9, the upper part 8 is thickened at one side of the gasket 7 and forms a step with the lower part 9, the height difference of the step is D, and the gasket 7 can move up and down to enable the upper part 8 and the lower part 9 to be respectively positioned between the compression nut 3 and the base 1;
when the upper part 8 is located between the gland nut 3 and the base 1, the length of the adjustment segment is L, and D > L.
The positioning pin 5 is a step-shaped positioning pin, the tail part is small, and the head part is large.
Comparing fig. 3 and 4, it can be seen that the gasket 7 is located on the left side of the base 1, and when the upper portion 8 of the gasket 7 is located between the base 1 and the pressing plate, the pressing screw 2 on the right side of the base 1 is shorter, so that the pressing plate is closer to the base 1 for pressing the automobile part 6. When the lower part 9 of the shim 7 is located between the base 1 and the pressure plate, the hold-down screw 2 on the right side of the base 1 is longer, making the pressure plate further away from the base 1 for loosening of the car part 6.
Since the height difference between the upper portion 8 and the lower portion 9 of the spacer 7 is D, the range of the length change of the pressing screw 2 on the right side of the base 1 is also D.
When the automobile parts 6 are to be loaded or unloaded, the length of the compression screw rod 2 on the right side of the base 1 is increased, the positioning pin 5 is not in contact with the pressure plate, and then the pressure plate is rotated to the position above the compression screw rod 2 without shielding the automobile parts 6.
When the automobile part 6 is required to be pressed, the length of the pressing screw rod 2 on the right side of the base 1 is shortened, the adjusting section of the positioning pin 5 is inserted into the second pin hole 11, and the pressing plate is contacted with the automobile part 6.
As shown in fig. 3, when the automobile part 6 is pressed, the upper part 8 of the gasket 7 is used for cushioning pressing. As soon as the compression nut 3 is loosened, the upper part 8 of the washer 7 will automatically rotate due to gravity, leaving the lighter lower part 9 above the upper part 8, as shown in fig. 4. The compression nut 3, the compression screw 2 and the pressing block 4 can be quickly withdrawn by utilizing the height difference of the steps of the gasket 7, and the quick compression and the loosening are realized through the height difference of the steps of the gasket 7.
In addition, after the compression nut 3 is loosened, the compression nut 3 is not screwed, the compression screw 2 can be moved left and right in the through hole and rotated, the compression screw 2 can be rotated, the pressing plate is rotated above the compression screw 2, and the position of the base 1 where the automobile part 6 is assembled is exposed and used for assembling and disassembling the automobile part 6.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
