For a better understanding of the technical solutions and advantages of the present application, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. The specific embodiments described herein are merely illustrative of the present application and are not intended to be limiting of the present application. In addition, the technical features mentioned in the embodiments of the present application described below may be combined and used unless they conflict with each other, thereby constituting other embodiments within the scope of the present application.
FIG. 1 shows a cross-sectional view of an assembly tool according to one embodiment of the present application. An assembly tool 100 as shown in fig. 1 may be used to assemble a hollow stud to a mounting base. The hollow post may be a post for mounting an optical tracking system in a medical procedure navigation system, having a hollow cavity. The hollow stud may be fitted by the fitting tool 100 to a mounting base which may have a first through hole for the hollow stud to pass through and mate with the outer surface of the hollow stud.
As shown in fig. 1, the assembly tool 100 may include a fixing bar 110, a rotary push bar 120, and a base 130. A first external thread is provided at the upper end of the fixing rod 110, a second external thread is provided at the lower end, and the mounting base is provided near the lower end of the fixing rod. In the process of assembling the hollow upright to the mounting base, the fixing rod 110 can penetrate through the hollow cavity of the hollow upright, that is, the hollow upright is sleeved outside the fixing rod 110.
The rotary push rod 120 has a second through-hole 121 in a direction perpendicular to the length direction thereof, and as shown in fig. 1, the second through-hole 121 is located at a central portion of the rotary push rod 120 and allows the upper end of the fixing rod 110 to pass therethrough. A first internal thread matched with the first external thread at the upper end of the fixing rod 110 is arranged in the second through hole 121. In the process of assembling the hollow column to the mounting base, the upper end of the fixing rod 110 may pass through the second through hole 121 of the rotary push rod 120, and the rotary push rod 120 may be rotated on the fixing rod 110 by the cooperation of the first internal thread and the first external thread. As the rotating push rod 120 rotates around the fixing rod 110 to make the rotating push rod 120 move downward relative to the fixing rod 110, the rotating push rod 120 can directly or indirectly push the hollow upright post sleeved outside the fixing rod 110 to move downward.
The base 130 has a non-penetrating hole 131 and an abutting portion 132, and as shown in fig. 1, the non-penetrating hole 131 is located at a central portion of the base 130 and allows the lower end of the fixing rod 110 to extend thereinto. A second internal thread engaged with the second external thread of the lower end of the fixing rod 110 is provided in the non-penetration hole 131. In the process of assembling the hollow upright to the mounting base, the base 130 is located below the mounting base, that is, the mounting base is located between the base 130 and the hollow upright sleeved outside the fixing rod 110. The lower end of the fixing rod 110 may be screwed into the non-through hole 131 by the matching of the second internal thread and the second external thread, so that the fixing rod 110 may be fixedly screwed with respect to the base 130, that is, the fixing rod 110 may be fixed with respect to the base 130. The abutting portion 132 may abut against a lower surface of the mounting base to fix the base 130 and the fixing rod 110 relative to the mounting base.
Fig. 2 shows a schematic cross-sectional view of a hollow upright and a mounting base when assembled with an assembly tool according to an embodiment of the present application. As shown in fig. 1 and 2, the process of assembling the hollow shaft 200 to the mounting base 300 using the assembling tool 100 is as follows: the hollow shaft 200 is first aligned and gently placed on the through-hole (i.e., the first through-hole) of the mounting base 300, and the fixing rod 110 of the assembly tool 100 is passed through the hollow cavity of the hollow shaft 200 and the through-hole of the mounting base 300, with the lower end of the fixing rod 110 protruding downward from the through-hole of the mounting base 300. Then, the lower end of the fixing rod 110 is fixedly coupled to the base 130 by means of a screw, and the base 130 is located under the mounting base 300. The rotary push rod 120 of the assembly tool 100 is then rotatably coupled to the upper end of the fixing rod 110 by screw-fitting, and the fixing rod 110 (together with the base 130) is moved upward with respect to the rotary push rod 120 and the hollow shaft 200 and the mounting base 300 by pushing the rotary push rod 120 to rotate around the fixing rod 110, that is, there is no relative movement between the hollow shaft 200 and the mounting base 300. As the mount 130 located below the mount base 300 is continuously raised with respect to the mount base 300, the abutting portion 132 of the mount 130 abuts against the lower surface of the mount base 300. Then, the rotating push rod 120 is continuously pushed to rotate around the fixing rod 110, and the rotating push rod 120 can directly or indirectly push the hollow upright 200 sleeved outside the fixing rod 110 to move downwards relative to the fixing rod 110 along with the rotating push rod 120. Since the mounting base 300 is abutted by the abutting portion 132 of the base 130 at this time, relative movement between the mounting base 300 and the base 130 and the fixing rod 110 will not occur any more, and therefore the hollow upright 200 will move downward relative to the mounting base 300 along with the rotating push rod 120, so that the hollow upright 200 is gradually fitted into the through hole of the mounting base 300 and forms an interference fit.
Therefore, since the abutting portion 132 of the base 130 fixedly connected with the fixing rod 110 abuts against the mounting base 300 upwards, the mounting base 300 is fixed relative to the fixing rod 110, and the rotating push rod 120 directly or indirectly pushes the hollow upright 200 downwards, so that the hollow upright 200 moves downwards relative to the fixing rod 110, the base 130 and the mounting base 300, thereby realizing the assembly of the hollow upright 200 and the mounting base 300, and forming an interference fit. By using the assembling tool, the mode of knocking by a heavy object in the prior art can be effectively replaced to realize the assembly between the hollow upright post and the mounting base 300. The operation process using the assembling tool is time-saving and labor-saving, and does not cause any damage to the hollow pillar and the mounting base 300, nor generate noise. Moreover, the assembly tool can ensure that the hollow upright post and the mounting base 300 are assembled in place, and can also accurately control the distance that the hollow upright post protrudes downward from the through hole of the mounting base 300.
FIG. 3 shows a cross-sectional view of a base of an assembly tool according to one embodiment of the present application. As shown in fig. 3, the base 130 may include a first base member 130A and a second base member 130B. The second base member 130B is disposed around the first base member 130A, and the first base member 130A and the second base member 130B can be fixedly connected by screws, or can be connected by other methods, such as welding, riveting, or the like, or the first base member 130A and the second base member 130B can be integrally formed.
As shown in fig. 3, the non-penetrating hole 131 is located in the first base member 130A, for example, at the center of the first base member 130A. The first base member 130A is smaller in size than the hollow cavity of the hollow stud such that the first base member 130A may extend into the hollow cavity of the hollow stud during assembly of the hollow stud to the mounting base.
FIG. 4 shows a schematic cross-sectional view of a base and hollow upright of an assembly tool as assembled according to one embodiment of the present application. As shown in fig. 3 and 4, the second base member 130B includes a stopper bottom plate 133 and an abutting portion 132. The abutting portion 132 is disposed around the first base member 130A, and the limiting bottom plate 133 is disposed under the first base member 130A and integrally formed with the abutting portion 132 to form the second base member 130B. The limit bottom plate 133 and the first base member 130A may be fixedly connected by screwing or the like, or may be integrally formed. In the process of assembling the hollow upright 200 to the mounting base, the abutting portion 132 is located outside the hollow upright 200, and the hollow upright 200 can gradually move downward along the gap between the abutting portions 132 of the first and second seat members 130A and 130B and abut against the restraining bottom plate 133, so that the restraining bottom plate 133 defines the lowest position of the hollow upright 200. When the lower surface S1 of the hollow upright 200 abuts against the upper surface S2 of the limiting bottom plate 133, the hollow upright 200 cannot move downward any more, and at this time, the rotating push rod 120 cannot be rotated around the fixing rod 110 and moved downward, that is, is assembled in place. At this time, the distance by which the lower end of the hollow upright 200 protrudes downward out of the through hole of the mounting base is approximately the distance between the lower surface S1 of the hollow upright 200 shown in fig. 4 (flush with the upper abutting surface of the abutting portion 132 in fig. 4) and the upper surface S2 of the stopper bottom plate 133.
From this, adopt above-mentioned erecting tool to assemble cavity stand and mounting base, will ensure that the two assembles to target in place to the design size of distance between the upper surface of the last face of leaning on of accessible change portion of leaning on and spacing bottom plate adjusts the distance that the lower extreme of the cavity stand stretched out the through-hole of mounting base downwards when accomplishing the assembly. For example, the abutting surface of the abutting part can have a preset height difference with the limiting bottom plate.
Fig. 5 shows a schematic cross-sectional view of a stop, a plain bearing and a thrust bearing of an assembly tool. As shown in fig. 1, 2, and 5, the assembly tool 100 may further include a stopper 140. The stopper 140 has a third through hole 141 in the center, and the size of the third through hole 141 is larger than the size of the fixing rod 110 and smaller than the size of the hollow cavity of the hollow upright column 200, so that in the process of assembling the hollow upright column 200 to the mounting base, the stopper 140 can be sleeved on the fixing rod 110 between the hollow upright column 200 and the rotary push rod 120 (as shown in fig. 2), and the hollow upright column 200 is pushed to move downward by the driving of the rotary push rod 120. The stopper 140 has a stepped part 142 on the outer surface thereof, the size of the lower part of the stepped part 142 is smaller than that of the hollow cavity of the hollow shaft 200, and the size of the upper part of the stepped part 142 is larger than that of the hollow shaft 200. In the process of assembling the hollow upright to the mounting base, the step part 142 may abut against the hollow upright and push the hollow upright 200 to move downward by the driving of the rotary push rod 120. The presence of the stopper 140 prevents the rotary push rod 120 from directly contacting the hollow post to be assembled, thereby reducing wear therebetween and more precisely defining the moving position of the hollow post.
According to one embodiment of the present application, the assembly tool 100 may further include a slide bearing 150. The sliding bearing 150 is fitted in the third through hole 141 of the stopper 140 by interference fit and sleeved at a position adjacent to the hollow pillar. The sliding bearing 150 may be made of a flexible wear-resistant material, for example, Polyetheretherketone (PEEK) material, so as to form a soft-hard fit with the fixing rod 110, and the sliding bearing 150 has an inner diameter greater than an outer diameter of the first external thread at the upper end of the fixing rod 110.
Because the stopper 140 is sleeved outside the fixing rod 110 and generates sliding friction with the outer surface of the fixing rod 110 in the assembling process, the sliding bearing 150 arranged at the front part of the stopper 140 in the moving direction forms soft and hard fit with the fixing rod 110, so that the abrasion between components can be reduced, and the service life of the whole device can be prolonged.
According to an embodiment of the present application, the assembly tool 100 may further include a thrust bearing 160 partially fitted in the third through hole 141 of the stopper 140 by interference fit, and the thrust bearing 160 is sleeved on the fixing rod 110 at a position between the rotary push rod 120 and the stopper 140 and is capable of pushing the stopper 140 to move downward by the driving of the rotary push rod 120. The thrust bearing 160 may be made of a flexible wear-resistant material (e.g., a peek material), and the inner diameter of the thrust bearing 160 is greater than the outer diameter of the first external thread of the upper end of the fixing rod 110.
The thrust bearing 160 is disposed between the rotary push rod 120 and the stopper 140, so that direct contact between the two can be prevented, abrasion between the components is reduced, the service life of the entire device is prolonged, and the thrust bearing 160 is partially pressed into the through hole 141 of the stopper 140 through interference fit, so that tight fit between the components can be further ensured.
It should be noted that the above-mentioned embodiments described with reference to the drawings are only intended to illustrate the present application and not to limit the scope of the present application, and those skilled in the art should understand that modifications or equivalent substitutions made on the present application without departing from the spirit and scope of the present application should be included in the scope of the present application. Furthermore, unless the context indicates otherwise, words that appear in the singular include the plural and vice versa. Additionally, all or a portion of any embodiment may be utilized with all or a portion of any other embodiment, unless stated otherwise.
