Description

Technical Field

[0001] The invention relates to the technical field of thrust spherical bearings, and in particular to a concave spherical surface and center solid body assembly. Background Art

[0002] During the production process of thrust spherical plain bearings, the end face of the outer ring needs to be processed and inspected, and the vertical distance between the end face and the center of the concave spherical surface of the outer ring needs to be controlled within an appropriate range. However, since the concave spherical surface of the outer ring is virtualized on the outer ring, it is difficult to accurately mark the precise position of the center point of the concave spherical surface of the outer ring with the existing technology, resulting in the inability to quickly and accurately measure the vertical distance between the end face of the concave spherical surface of the outer ring and the center point of the concave spherical surface. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a concave spherical center physical device, which mainly solves the technical problem that it is difficult to accurately measure the vertical distance between the center point of the concave spherical surface of the outer ring of the thrust spherical bearing and the end face of the concave spherical surface.

[0004] To achieve the above object, the present invention is achieved through the following technical solutions:

[0005] A concave spherical surface center solidification device comprises a contact surface seat and a solidification rod, wherein an annular protrusion for contacting the concave spherical surface to be measured is formed at the bottom of the contact surface seat, and a central through hole located at the center of the annular protrusion is formed on the contact surface seat, and the lower end portion of the solidification rod is inserted into the central through hole of the contact surface seat, and the solidification rod is a telescopic rod structure with adjustable and lockable length, a solidification ball head is arranged at the top of the solidification rod, and a contact surface ball head is arranged at the bottom of the solidification rod, the centers of the solidification ball head and the contact surface ball head are both located on the central axis of the solidification rod, and a locking structure for locking the solidification rod with a pre-adjusted length to the contact surface seat is arranged between the contact surface seat and the solidification rod.

[0006] Furthermore, the annular end portion on the bottom of the annular protrusion for contacting with the concave spherical surface has a rounded structure.

[0007] Furthermore, the locking structure includes a locking cone sleeve, a locking nut sleeve, and an inner tapered hole and an outer threaded portion formed at the upper end of the contact surface seat, the inner tapered hole is coaxially arranged with the central through hole, the locking cone sleeve is sleeved on the materialized rod, the locking nut sleeve can be axially rotatably sleeved on the materialized rod, and the upper end of the locking nut sleeve forms a limiting end portion and abuts against the upper end of the locking cone sleeve, an inner threaded portion matching the outer threaded portion on the contact surface seat is provided on the inner wall of the locking nut sleeve, and the locking nut sleeve is threadedly connected to the upper end of the contact surface seat through the threaded cooperation of the outer threaded portion and the inner threaded portion, so that when the locking nut sleeve is tightened, the locking cone sleeve can be squeezed toward the inner direction of the inner tapered hole on the contact surface seat through the limiting end portion of the locking nut sleeve, thereby causing the locking cone sleeve to shrink and hold the materialized rod tightly.

[0008] Further, an annular groove is formed in the set screw bushing, and a plurality of screws are connected to the peripheral wall of the set screw nut sleeve and laterally inserted into the annular groove. When the set screw nut sleeve is rotated, the set screw nut sleeve can drive the set screw bushing to withdraw from the inner tapered hole of the contact seat through the mutual cooperation of the screws and the annular groove, so as to release the clamping effect of the set screw bushing on the solidified rod.

[0009] Further, the concave spherical surface is the concave spherical surface structure of the outer ring of the thrust joint bearing.

[0010] Further, the solidified rod includes an upper rod portion and a lower rod portion. The upper rod portion and the lower rod portion are coaxially threadedly connected together through mutually adapted internal and external thread structures to form a telescopic rod structure with adjustable length.

[0011] Further, a sizing nut is screwed on the lower rod portion.

[0012] Further, the solidified ball head is arranged at the top of the upper rod portion, and the contact ball head is arranged at the bottom of the lower rod portion.

[0013] Further, the outer diameter of the upper rod portion is adapted to the aperture of the central through hole on the contact seat.

[0014] The above technical solutions have the following advantages or beneficial effects:

[0015] In the concave spherical center solidified tooling of the present invention, an annular protrusion is arranged at the bottom of the contact seat, and a central through hole is formed in the contact seat. The lower end of the solidified rod is inserted through the central through hole. And a solidified ball head and a contact ball head are respectively arranged at the top and the bottom of the solidified rod. During use, first, the telescopic solidified rod is adjusted to a suitable length according to the radius of the concave spherical surface, and then the contact surface and the solidified rod are assembled together, and the annular protrusion of the contact seat and the contact ball head of the solidified rod are simultaneously abutted against the concave spherical surface to be measured. Then, the solidified rod and the contact seat are locked together through the locking structure. At this time, the center of the solidified ball head on the solidified rod can coincide with the center point of the concave spherical surface and solidify it. After that, the vertical distance A value between the center point of the concave spherical surface and the end surface of the concave spherical surface can be quickly and conveniently measured by using a measuring tool.

It can be understood that, in the present embodiment, an annular protrusion 11 is provided on the bottom of the contact surface seat 1, and a central through hole is opened on the contact surface seat 1, the lower end of the materialized rod 2 is inserted into the central through hole, and a materialized ball head 21 and a contact surface ball head 22 are respectively provided on the top and bottom of the materialized rod 2. When in use, the length-adjustable materialized rod 2 is first adjusted to a suitable length according to the radius of the concave spherical surface 4, and then the contact surface seat 1 and the materialized rod 2 are assembled together, and the annular protrusion 11 of the contact surface seat 1 and the contact surface ball head 22 of the materialized rod 2 are simultaneously abutted against the concave spherical surface 4 to be measured, and then the materialized rod 2 and the contact surface seat 1 are locked together by the locking structure 3. At this time, the center of the materialized ball head 21 on the materialized rod 2 can coincide with the center point of the concave spherical surface 4 and materialize it. Afterwards, the vertical distance A between the center point of the concave spherical surface 4 and the end face of the concave spherical surface 4 can be quickly and conveniently measured using a measuring tool.

[0027] Please refer to the attached Figure 3 , Attachment Figure 6 In one preferred embodiment, the annular end portion of the bottom of the annular protrusion 11 for contacting the concave spherical surface 4 is a rounded structure. It can be understood that by configuring the annular end portion of the bottom of the annular protrusion 11 as a rounded structure, an accurate point contact fit can be formed between the bottom of the annular protrusion 11 and the concave spherical surface 4 to be measured, which is conducive to improving the materialization accuracy of the center point of the concave spherical surface, and further improving the measurement accuracy of the vertical distance A between the center point and the end face.

The threaded connection to the upper end of the contact surface seat 1 ... However, those skilled in the art should understand that in other embodiments, the materialized rod 2 can also be locked with the contact surface seat 1 through other locking structures, which are not limited to the specific implementation methods disclosed in this embodiment. For example, by opening a radial locking hole on the side of the contact surface seat, the materialized rod 2 and the contact surface seat 1 are locked together by a fixing pin locked in the radial locking hole. As long as the contact surface ball head 22 on the bottom of the materialized rod 2 and the bottom of the annular protrusion 11 on the contact surface seat 1 are both in contact with the concave spherical surface 4, the materialized rod 2 and the contact surface seat 1 can be locked together by the locking structure to prevent relative movement.

[0029] Please refer to the attached Figure 1 To Attachment Figure 3 In one preferred embodiment, an annular groove is provided on the fixing cone sleeve 31, and a plurality of screws 33 are connected to the peripheral wall of the fixing nut sleeve 32 and are laterally inserted into the annular groove, so that when the fixing nut sleeve 32 is loosened, the fixing nut sleeve 32 can drive the fixing cone sleeve 31 to withdraw from the inner tapered hole of the contact surface seat 1 through the mutual cooperation between the screws 33 and the annular groove, so as to release the clamping effect of the fixing cone sleeve 31 on the materialized rod 2. With such a design, the concave spherical surface center solidification equipment can be applied to the solidification of concave spherical surfaces of various spherical surface radius sizes. Before use, the fixing nut sleeve 32 can be loosened to remove the solidified rod 2, and then the solidified rod 2 can be accurately adjusted to a suitable length by using an outside diameter micrometer, and then the solidified rod 2 is reset, and the annular protrusion 11 of the contact surface seat 1 is pressed against the concave spherical surface 4 to be measured. When the contact surface ball head 22 at the bottom of the solidified rod 2 abuts against the concave spherical surface 4, the fixing nut sleeve 32 can be tightened to lock the solidified rod 2 and the contact surface seat 1. Then, the vertical distance B between the top of the solidified ball head 21 and the outer ring end face can be measured by using a measuring tool, and the vertical distance A between the ball center point of the solidified ball head 21 (i.e., the ball center point of the concave spherical surface 4) and the outer ring end face is equal to B-RG.

[0030] Please refer to the attached Figure 5 , Attachment Figure 6, in a preferred embodiment, the concave spherical surface 4 is the concave spherical surface structure of the outer ring of the thrust joint bearing.

The upper rod portion 23 and the lower rod portion 24 are coaxially threadedly connected together through mutually adapted internal and external thread structures to form a telescopic rod structure with adjustable length. In this embodiment, preferably, a sizing nut 25 is screwed onto the lower rod portion 24. It can be understood that before use, the lengths of the upper rod portion 23 and the lower rod portion 24 are adjusted according to the spherical radius of the concave spherical surface 4.

[0033] Please refer to the appendix Figure 3 , in a preferred embodiment, the outer diameter of the upper rod portion 23 is adapted to the aperture diameter of the central perforation on the contact seat 1. It can be understood that by configuring the outer diameter of the upper rod portion 23 to be adapted to the aperture diameter of the central perforation on the contact seat 1, the insertion connection stability between the solid rod 2 and the contact seat 1 can be improved, which is conducive to improving the spherical center solidification accuracy and ensuring the accuracy of subsequent A value measurement.
