fig. 7 and 8: the base is rotated by 180 degrees.

In the figure: 1. a clamp cushion block, 2.1 inner hexagon bolts, 3 a clamp platform, 4 an outer hexagon wrench, 5 a small bevel gear with a handle, 6 a large bevel gear, 7 an inner hexagon wrench, 8 a top cover, 9 a base,

the specific implementation mode is as follows:

for the purpose of enhancing the understanding of the present invention, the following detailed description is made with reference to the accompanying drawings.

Example 1: referring to fig. 1, the dismounting tool for clamp cushion blocks of narrow lap welding machines comprises a large bevel gear 6, a small bevel gear 5 with a handle, an inner hexagonal wrench 7, a top cover 8 and a base 9, wherein a central hole of the large bevel gear is in a regular hexagon shape and is matched with the inner hexagonal wrench 7, the inner hexagonal wrench 7 slides in the central hole of the large bevel gear 6, and the top cover 8 and the base 9 are installed on a device body through bolts. The centre bore of top cap is the round hole, and interior hexagonal spanner 7 is downthehole rotation, and the central point of base 9 puts and interior hexagonal bolt's position distance 19mm, and is consistent with cushion construction bolt 2.1 and 2.2 skew cushion central point apart from putting, assembly and disassembly tools includes outer hexagonal spanner 4, and this outer hexagonal spanner 4 can directly pull interior hexagonal spanner 7, solves the problem that turns to spanner moment to the younger side, designs the counter bore on the base, just in time overlaps on the cushion, and spanner center and the eccentric distance in base center are exactly cushion construction bolt center and cushion central point apart from, and interior hexagonal spanner and gear wheel design become the feather key and connect. The hexagon is processed into to interior hexagonal spanner wholly, and big bevel gear hole is processed into interior hexagon, and interior hexagonal spanner can reciprocate by big bevel gear relatively like this, and the button head is handled at interior hexagonal spanner both ends, is convenient for fix a position. When the cushion block bolt is disassembled, the tool is sleeved on the cushion block, the tool is rotated to enable the handle to be basically perpendicular to the central line of the unit, and the wrench is pressed down by the tool, so that the positioning of the inner hexagonal wrench is completed. The upper part of the bolt is unscrewed by an external hexagonal wrench, and then the bolt is disassembled by a bevel gear steering wrench. Before another bolt is removed, the bevel gear steering wrench and the base are installed by rotating 180 degrees, and the bolt can be removed by using the same steps.

Installation and working process: referring to fig. 1-8, a clamp pad 1 of the welding machine shown in fig. 1 is fixed on a clamp platform 3 by two M6 hexagon socket head cap bolts 2.1 and 2.2, and the diameter of the pad is 60mm and is 0.3mm higher than the clamp platform. The distance between two hexagon socket head cap screws is 38mm, which is equivalent to 19mm from the center position. The cushion block disassembling tool consists of a large bevel gear 6 and a small bevel gear 5 with a handle, wherein the center hole of the large bevel gear is in a regular hexagon shape and is matched with an inner hexagonal wrench 7, and the inner hexagonal wrench 7 can slide in the center hole of the large bevel gear 6. Top cap 8 and base 9 pass through the bolt and install on the device body, and the centre bore of top cap is the round hole, and interior hexagonal wrench 7 can rotate in the hole, and the central point of base 9 puts and interior hexagonal bolt's position apart from 19mm, and it is unanimous with cushion mounting bolt 2.1 and 2.2 skew cushion central point put the distance. The device is also provided with an outer hexagon wrench 4 which can directly pull an inner hexagon wrench 7, so that the problem that the torque of the steering wrench is small is solved. Before the cushion block bolt 2.2 is disassembled, the base is installed according to the figure 5 and the figure 6, the base is sleeved on the cushion block at the moment, the inner hexagonal wrench 7 basically falls on the bolt 2.1, the rotating handle 5 can be disassembled, if the torque is not large enough, the outer hexagonal wrench 4 can be used for directly wrenching the inner hexagonal wrench 7, and after the inner hexagonal bolt 2.2 is loosened, the handle 5 continues to be rotated, and the bolt 2.2 is unscrewed. Since the allen wrench 7 can slide in the large bevel gear 6, the whole process is very smooth. After the hexagon socket head cap screw 2.2 is removed, the base 9 is mounted according to fig. 7 and 8, and the hexagon socket head cap screw 2.1 can be removed by the same operation.
