Description

Technical Field

[0001] The invention relates to a floating washer assembly. Background Art

[0002] Thin-walled parts, such as round tubes, are usually processed with washers and positioning mandrels. The positioning mandrel passes through the washers, and then the thin-walled parts are put on the positioning mandrel. Pressure is applied to one end of the thin-walled parts, while the other end is supported on the washers under the action of pressure. Since the inner hole and end face of thin-walled parts are not perpendicular, the thin-walled parts are easily deformed by pressure, making the thin-walled parts unqualified. For this reason, floating washers are often used to avoid such problems. In the prior art, there are two types of floating washers commonly used. The first type of floating washers is a floating washer with two arc-shaped support strips, and the end faces of thin-walled parts are supported on the arc-shaped support strips. The disadvantage of this type of floating washers is that the floating is not flexible enough and can only float in a specific direction, and there are only two points of contact with the end faces of thin-walled parts, and the rigidity is insufficient. The other type of floating washers includes a base and a spherical floating block. A spherical groove is provided on the base, and the floating block fits in the spherical groove. The floating block can rotate in the spherical groove. This type of floating washer can float in any direction, but the disadvantage is that due to the large friction between the floating block and the base, the floating block cannot rotate quickly, resulting in insufficient flexibility. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a floating washer assembly, in which the floating block can float in any direction and has good flexibility and rigidity.

[0004] In order to solve the above technical problems, the technical solutions provided by the present invention are as follows:

[0005] A floating washer assembly comprises: a fixed seat, a connecting plate, a floating block, a first pin body and a second pin body, the connecting plate is provided with an avoidance hole, the connecting plate is located between the fixed seat and the floating block, the fixed seat and the connecting plate are movably connected, the floating block and the connecting plate are movably connected, and there is a gap between the connecting plate and the fixed seat, and there is a gap between the floating block and the connecting plate; a first accommodating cavity is provided between the connecting plate and the floating block, a second accommodating cavity is provided between the fixed seat and the connecting plate, two of the first accommodating cavity and two of the second accommodating cavity are provided, the first pin body is installed in the first accommodating cavity, the second pin body is installed in the second accommodating cavity, the axis lines of the two first pin bodies are in the same straight line and pass through the center of the avoidance hole, the axis lines of the two second pin bodies are in the same straight line and pass through the center of the avoidance hole, and the two first pin bodies and the two second pin bodies are cross-arranged.

[0008] Preferably, it also includes a limit pin, which is fixed on the floating block or the fixed seat, and one end of the limit pin abuts against the first pin body or the second pin body to fix the first pin body or the second pin body on the connecting plate.

[0009] Preferably, both the floating block and the fixed seat are provided with mounting holes, the limiting pin is located in the mounting hole, and the limiting pin is interference fit with the mounting hole.

[0010] Preferably: it also includes an elastic sealing ring, the outer ring of the floating block is provided with a protective sleeve, and the protective sleeve is arranged on the outer sides of the connecting piece and the fixing seat; the elastic sealing ring is installed on the outer side of the fixing seat, and the elastic sealing ring contacts the inner wall of the protective sleeve.

[0011] Preferably: it also includes a connecting member, a stopper is provided at the end of the connecting member, a fifth groove and a first through hole connected to the fifth groove are provided on the floating block, a second through hole is provided on the connecting plate, a threaded hole is provided on the fixing seat, the connecting member passes through the first through hole and the second through hole and is threadedly connected to the threaded holes, and the stopper is located in the fifth groove; there is a gap between the connecting member and the inner walls of the first through hole and the second through hole, and there is a gap between the stopper and the inner wall of the fifth groove.

[0035] like Figure 1 — Fig. 9 As shown,

[0036] Embodiment 1:

[0037] A floating washer assembly, comprising:

[0038] A fixed seat 1, a connecting piece 2, a floating block 3, a first pin body 4 and a second pin body 5, the connecting piece 2 is provided with an avoidance hole, the connecting piece 2 is located between the fixed seat 1 and the floating block 3, the fixed seat 1 and the connecting piece 2 are movably connected, the floating block 3 and the connecting piece 2 are movably connected, and there is a gap between the connecting piece 2 and the fixed seat 1, and there is a gap between the floating block 3 and the connecting piece 2; a first accommodating cavity is provided between the connecting piece 2 and the floating block 3, a second accommodating cavity is provided between the fixed seat 1 and the connecting piece 2, two first accommodating cavities and two second accommodating cavities are provided, the first pin body 4 is installed in the first accommodating cavity, the second pin body 5 is installed in the second accommodating cavity, the axis lines of the two first pin bodies 4 are in the same straight line and pass through the center of the avoidance hole, the axis lines of the two second pin bodies 5 are in the same straight line and pass through the center of the avoidance hole, and the two first pin bodies 4 and the two second pin bodies 5 are arranged in a cross. Specifically, the first pin body 4 and the second pin body 5 are both cylindrical pins, and the shapes of the inner walls of the first accommodating cavity and the second accommodating cavity correspond to the surface shapes of the first pin body 4 and the second pin body 5, and are both arc-shaped. Specifically, the fixed seat 1 and the floating block 3 are also provided with avoidance holes which are connected with the avoidance holes on the connecting piece 2 for the positioning core shaft to pass through.

[0039] In this way, when in use, the fixing seat 1 is fixed, the positioning mandrel passes through the avoidance hole, and then the thin-walled part is sleeved on the positioning mandrel, and the end face of the thin-walled part is supported on the floating block 3. Since the floating block 3 is supported on the first pin body 4, the floating block 3 can be tilted toward both sides of the first pin body 4, but cannot be tilted toward the area near the first pin body 4. At the same time, since the connecting piece 2 can be tilted toward both sides of the second pin body 5, but cannot be tilted toward the area near the first pin body 4, since the axis lines of the two first pin bodies 4 are perpendicular to the axis lines of the two second pin bodies 5, the tilting range of the connecting piece 2 covers the area near the first pin body 4, and the tilting range of the floating block 3 covers the area near the second pin body 5, so that the floating block 3 can be tilted in any direction of 360 degrees; at the same time, since the first pin body 4 and the second pin body 5 are used as support, the floating is flexible and responsive; in addition, since the end face of the entire thin-walled part is in contact with the floating block 3, the rigidity of the floating washer assembly is good, so that the floating block can float in any direction and has good flexibility and rigidity.

[0040] In addition, the front and back sides of the connecting piece 2 are respectively provided with a first groove 22 and a second groove 23, the back side of the floating block 3 is provided with a third groove 31, and the front side of the fixing seat 1 is provided with a fourth groove 11. The first groove 22 and the third groove 31 are combined to form a first accommodation cavity, and the second groove 23 and the fourth groove 11 are combined to form a second accommodation cavity. Specifically, the first groove 22, the second groove 23, the third groove 31 and the fourth groove 11 are all arc grooves.

[0041] In addition, the first groove 22 and the second groove 23 are connected to the surface of the connecting piece 2 , the third groove 31 is connected to the surface of the floating block 3 , and the fourth groove 11 is connected to the surface of the fixing seat 1 .

[0042] In this way, after assembling the floating block 3, the connecting plate 2 and the fixed seat 1, the first pin body 4 can be inserted into the first accommodating cavity, and then the second pin body 5 can be inserted into the second accommodating cavity, instead of first placing the first pin body 4 into the first groove 22 and the fourth groove 11, and then connecting the floating block 3, the connecting plate 2 and the fixed seat 1. This will cause the first pin body 4 and the second pin body 5 to be placed inaccurately, and during the assembly process, the first pin body 4 will fall out of the first groove 22, and the second pin body 5 will fall out of the fourth groove 11.

[0043] In addition, it also includes a limit pin 6, which is fixed on the floating block 3 or the fixed seat 1, and one end of the limit pin 6 rests on the first pin body 4 or the second pin body 5 to fix the first pin body 4 or the second pin body 5 on the connecting plate 2.

[0044] In this way, it is possible to prevent the first pin body 4 from falling out of the first accommodating cavity and the second pin body 5 from falling out of the second accommodating cavity.

[0045] In addition, both the floating block 3 and the fixed seat 1 are provided with mounting holes, the limiting pin 6 is located in the mounting hole, and the limiting pin 6 is interference fit with the mounting hole.

[0046] This makes it easier to assemble the limiting pin 6 .

[0047] Embodiment 2:

[0048] In this embodiment, an elastic sealing ring 7 is further included, and a protective sleeve 32 is provided on the outer ring of the floating block 3. The protective sleeve 32 is sleeved on the outer sides of the connecting piece 2 and the fixing seat 1; the elastic sealing ring 7 is installed on the outer side of the fixing seat 1, and the elastic sealing ring 7 contacts the inner wall of the protective sleeve 32. Specifically, the elastic sealing ring 7 is made of rubber material.

[0049] In this way, the floating block 3 can better fit with thin-walled parts under the elastic force of the elastic sealing ring 7. At the same time, the elastic sealing ring 7 can also prevent debris from entering the gap between the fixed seat 1, the connecting piece 2, and the floating block 3, as well as the first accommodating cavity and the second accommodating cavity, thereby affecting the floating of the floating block 3.

[0050] In addition, it also includes a connecting member 8, a stopper 81 is provided at the end of the connecting member 8, a fifth groove 33 and a first through hole 34 connected to the fifth groove 33 are provided on the floating block 3, a second through hole 24 is provided on the connecting plate 2, and a threaded hole 12 is provided on the fixing seat 1, the connecting member 8 passes through the first through hole 34 and the second through hole 24 and is threadedly connected to the threaded hole 12, and the stopper 81 is located in the fifth groove 33; there is a gap between the connecting member 8 and the inner walls of the first through hole 34 and the second through hole 24, and there is a gap between the stopper 81 and the inner wall of the fifth groove 33.

[0051] In this way, a movable connection between the floating block 3, the connecting piece 2 and the fixing seat 1 can be achieved.

[0052] In addition, the floating block 3 is provided with a third through hole 35 , the connecting piece 2 is provided with a fourth through hole 21 , and the fixing seat 1 is provided with a sixth groove 13 and a fifth through hole 14 communicating with the sixth groove 13 .

[0053] In this way, when fixing the floating washer assembly, bolts can be inserted into the third through hole 35, the fourth through hole 21 and the fifth through hole 14 to connect with other components, thereby fixing the entire floating washer assembly.

[0054] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
