Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A boneless coil mechanical testing device: referring to fig. 1 and 2, the base comprises a base 1 with a T-shaped groove, a T-shaped nut 2 is placed in the T-shaped groove of the base 1, the T-shaped nut 2 is used for fixing relevant parts on the base 1, only one T-shaped nut 2 is shown in fig. 1, and other T-shaped nuts are omitted. The first screw 4 fixes the upright 3 to the base 1.

The main shaft 5 is inserted into the hole at the upper end of the upright post 3, and the main shaft 5 is fixed on the upright post 3 through the spring retainer ring 10, the first gasket 9, the second gasket 8, the spring washer 7 and the first nut 6.

The right end of the main shaft 5 is provided with a hole, a second screw 20 sequentially penetrates through a left lower gland 21, the main shaft 5, a left upper gland 11 and a spring washer 12, the glands are all provided with semicircular holes to be matched with the main shaft 5, and the left lower gland 21 and the left upper gland 11 can be fixed on the main shaft 5 by screwing a second nut 13 (see a partial enlarged view in fig. 3).

The shaft sleeve 17 is inserted into the shaft at the right end of the main shaft 5, the shaft sleeve 17 is provided with a boss, the boss is provided with two threaded holes, and the two threaded holes are symmetrically distributed at 180 degrees. The right lower gland 18 and the right upper gland 16 are both provided with semicircular holes to be matched with the main shaft 5; the right lower gland 18 and the right upper gland 16 are both processed with semicircular grooves to be matched with bosses of the shaft sleeve 17. The right lower gland 18 and the right upper gland 16 are fixed on the shaft sleeve 17 by a third screw 19 and a fourth screw 15 respectively.

The shaft sleeve 17 is connected with an inner nut at the left end of the S-shaped tension sensor 22 through an external thread at the right end of the shaft sleeve, the S-shaped tension sensor 22 is fixed on the support 23 through a fifth screw 24, the support 23 is fixed on the moving platform 25 through a screw, and the moving platform 25, the guide rail 26, the lead screw 41, the lead screw nut 29, the coupler 27, the first vertical plate 28, the second vertical plate 30, the bottom plate 33, the L-shaped support 32 and the motor 31 form a linear moving platform.
