Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1 and 2, the utility model discloses a floating seat positioning assembly, including the anchor clamps body 3, fixed baseplate 4 and floating seat 2, fixed baseplate 4 passes through bolt detachably fixed mounting on anchor clamps body 3. Taking the direction shown in fig. 1 as a reference, the middle part of the fixed base 4 is provided with a vertical clearance hole 42, and the clearance hole 42 penetrates through the whole fixed base 4 from top to bottom.

As shown in fig. 1, a T-shaped circular hole 21 is formed in the center of the floating seat 2 from top to bottom, and the T-shaped circular hole 21 is large in top and small in bottom. The T-shaped circular hole 21 is arranged coaxially with the clearance hole 42 of the fixed base 4. The fixing base 4 is vertically provided with a limiting part 41, the limiting part 41 protrudes upwards to extend into the T-shaped round hole 21 and extends to the step surface of the large-diameter section and the small-diameter section of the T-shaped round hole 21, and the outer side wall of the limiting part 41 is in sliding fit with the side wall of the T-shaped round hole 21.

As shown in fig. 1, a gap is formed between the top surface of the lower portion of the fixed base 4 and the bottom surface of the slide floating base 2. The bottom of the floating seat 2 protrudes outwards to form a limit bulge 22, and the clamp body 3 is provided with a limit flange 31 close to the floating seat 2. The limit flange 31 is located above the limit protrusion 22 and is used to limit the limit position of the limit protrusion 22 moving upwards, and limit the upward stroke of the floating seat 2. Naturally, the downward travel of the floating platform 2 is limited by the fixed base 4.

In the scheme, a plurality of elastic connecting pieces are arranged between the lower part of the fixed base 4 and the floating seat 2. In the present embodiment, three elastic connecting members are explained. A plurality of guide holes 23 are vertically formed in the floating seat 2, and each elastic connecting piece corresponds to one guide hole 23 from top to bottom. Each elastic connecting piece comprises a guide screw 8 and a pressure spring 9, the guide screw 8 penetrates through the fixed base 4 from bottom to top and then extends into the guide hole 23 of the floating base 2, the tail part of the guide screw 8 is in threaded connection with the fixed base 4, but the head part of the guide screw 8 is in up-and-down sliding fit with the floating base 2. And the compression spring 9 is telescopically sleeved on the guide screw 8, and the compression spring 9 is positioned between the fixed base 4 and the floating seat 2.

As shown in fig. 1, three elastic connecting pieces are uniformly arranged along the circumferential direction of the clearance hole 42 of the fixed base 4. When the floating seat 2 is pressed downwards, the floating seat 2 slides upwards and downwards along the cavity wall of the sliding cavity; the pressure on the floating seat 2 is stopped, and the floating seat 2 slides upwards under the action of the pressure spring 9. The specific implementation principle of the scheme is as follows: as shown in fig. 1, the cylindrical protruding portion of the part 1 is inserted into the large diameter section of the T-shaped circular hole 21 from top to bottom according to the direction shown in the figure, the part 1 is radially limited and fixed by the large upper hole of the T-shaped circular hole 21, meanwhile, the part 1 continues to be downward until being attached to the step surface of the T-shaped circular hole 21, and then the T-shaped circular hole 21 continues to be capable of axially limiting and fixing the cylindrical protruding portion of the part 1. This solution is more effective, in particular with respect to the spacing and fixing of the part 1 with conical projections, as shown in figure 2.

As shown in fig. 1 and 2, for the connection between the guide screw 8 and the floating seat 2, the guide screw 8 may penetrate the floating seat 2, or of course, may penetrate the floating seat 2. When the guide screw 8 penetrates through the floating seat 2, the guide hole 23 is a through hole, the contact section of the guide screw 8 and the floating seat 2 is prolonged, and further the guide screw 8 can better perform sliding limit on the floating seat 2, but metal chips generated by processing the part 1 are easily clamped into the guide hole 23; when the guide screw 8 does not penetrate through the floating seat 2, the contact section of the guide screw 8 and the floating seat 2 is shortened, which easily causes deviation of the up-and-down sliding of the floating seat 2.

In this solution, as shown in fig. 1, in the case where the guide screw 8 does not penetrate the floating seat 2, the floating seat 2 can be better restrained by adding the sliding column 5 between the fixed base 4 and the floating seat 2. A hexagon screw 6 is in threaded connection with the fixed base 4, the hexagon screw 6 penetrates through the fixed base 4 from bottom to top, meanwhile, a blind hole 24 is formed in the floating seat 2, the blind hole 24 is parallel to the axis of the chip removal hole 42, and the hole opening of the blind hole 24 faces downwards; the blind hole 24 is coaxial with the hexagon screw 6, the sliding column 5 is inserted into the blind hole 24, the sliding column 5 is in up-and-down sliding fit with the blind hole 24, and the sliding column 5 is fixed with the upper part of the hexagon screw 6 through threads. As shown in fig. 1, the sliding column 5 must also be slidably mounted up and down between the floating mount 2 and the fixed base 4.

As shown in fig. 2, in the case that the guide hole 23 penetrates the floating seat 2 upwards, the floating seat 2 can be guided and limited by additionally arranging the sliding column 5, and the guide screw 8 can be further guided and stabilized by additionally arranging the countersunk screw 7. As shown in fig. 2, a countersunk screw 7 is provided at the step surface of the T-shaped circular hole 21, the countersunk screw 7 penetrates through the guide hole 23 from top to bottom, the countersunk screw 7 is screwed with the floating seat 2, and the lower end of the countersunk screw 7 abuts against the guide screw 8. The guide screw 8 is pressed by the countersunk head screw 7, so that the guide screw 8 can be more firmly connected with the fixed base 4, the reverse friction force is provided for the guide screw 8, and particularly, metal scraps can be prevented from entering the guide hole 23.

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 present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
