Description

Technical Field

[0001] The invention belongs to the technical field of ball socket liner grinding, and in particular relates to a grinding device for a spherical bushing for an automobile. Background Art

[0002] The fit between the ball head and the socket is a sliding surface contact, so in order to ensure smooth rotation of the contact parts, both the ball head and the socket need to be ground; compared with the outer surface of the ball head that needs to be ground, the grinding of the socket lining is more difficult; this is mainly because the internal space of the socket lining is larger than the opening and both are smooth curved surfaces, making it inconvenient for the tool to enter, and after entering, it is also inconvenient to adjust the direction of the tool base a second time in the narrow space. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a grinding device for a spherical bushing for an automobile, which can automatically change the angle of the grinding head through a smaller linkage structure after extending into the interior of the ball socket; if one wants to adjust the direction of the grinding head in a narrow space so that the working range of the smaller grinding head can radiate to the inner wall of the entire ball socket liner, a motor cannot be set at the end of the rotating spindle. In order to solve this problem, the present invention creatively proposes an adaptive rotary grinding mechanism, which can not only controllably adjust the direction of the deflection rod through the centrifugal force generated by the rotation of the rotating spindle, but also automatically adjust the extrusion pressure between the grinding head and the ball socket liner, thereby overcoming the technical contradiction that the extrusion pressure cannot be too large or too small; if the extrusion pressure is too small, the grinding efficiency will be seriously affected, and if the extrusion pressure is too large, the top grinding head will not be able to smoothly enter the ball socket liner.

[0004] Moreover, in order to simplify the operation steps and improve the clamping accuracy, the present invention also proposes a ball-and-socket automatic clamping mechanism, which can automatically adjust the direction and position of the circular shaft part during the clamping process through evenly arranged and synchronously moving transverse clamping blocks.

[0048] The ball and socket automatic clamping mechanism 2 includes a ball and socket body 22, a transverse clamping assembly 23 and a longitudinal pressure assembly 24. The transverse clamping assembly 23 is arranged in a ring on the main body bottom plate 4, the ball and socket body 22 is arranged on the transverse clamping assembly 23, and the longitudinal pressure assembly 24 is located above the transverse clamping assembly 23.

[0049] The socket liner 25 is actually divided into multiple areas. The grinding head 13 can grind different areas at different rotation speeds of the rotating spindle 15. By controlling the rotation speed of the rotating spindle 15, the progress and rhythm of the grinding can be controlled.

[0050] The ball socket body 22 is composed of a ball socket lining 25, a step portion 26 and a circular shaft portion 27. The adaptive torsion component 6 and the self-retractable pressure component 7 are located in the ball socket lining 25. The transverse clamping component 23 includes a bottom slide 28, a transverse clamping block 29 and an inclined slide 30. The bottom slide 28 is fixed to the main body bottom plate 4. The bottom of the transverse clamping block 29 is provided with a bottom slide bar 34. The transverse clamping block 29 is engaged and slidably arranged in the bottom slide 28 through the bottom slide bar 34. The transverse clamping block 29 is also provided with a slope slide bar 35. The inclined slide 30 is engaged and slidably arranged on the slope slide bar 35.

[0051] The longitudinal pressure assembly 24 includes an annular pressure plate 31, a pressure plate return spring 32 and a lifting guide bar 33. The inclined slide groove 30 is fixed to the annular pressure plate 31. The outer ring of the annular pressure plate 31 is evenly distributed with square notches 36. The lifting guide bar 33 is fixed to the main body bottom plate 4. The annular pressure plate 31 is slidably arranged on the lifting guide bar 33 through the square notches 36. The pressure plate return spring 32 is arranged between the annular pressure plate 31 and the main body bottom plate 4.

[0052] Through the linkage of the ball socket automatic clamping mechanism 2, the ball socket body 22 can be automatically clamped and fixed by applying pressure during the process of the adaptive rotary grinding mechanism 1 descending into the ball socket liner 25. During this process, the axial position of the ball socket body 22 can also be automatically adjusted, so that the ball socket body 22 and the rotating spindle 15 are automatically transformed into a coaxial arrangement state; and when the adaptive rotary grinding mechanism 1 rises and resets, the horizontal clamping block 29 can also be automatically withdrawn to facilitate the removal of the ball socket body 22.

[0053] The adaptive rotary grinding mechanism 1 includes a beam assembly 5, an adaptive torsion assembly 6 and a self-telescopic pressure assembly 7. The beam assembly 5 is arranged on the lifting execution assembly 38, the adaptive torsion assembly 6 is rotatably arranged at the bottom of the beam assembly 5, and the self-telescopic pressure assembly 7 is symmetrically arranged at both ends of the adaptive torsion assembly 6.

[0054] The adaptive rotary grinding mechanism 1 can actively control the horizontal angle of the self-retractable pressure component 7 according to the rotation speed, so that the grinding range of the adaptive rotary grinding mechanism 1 can cover the entire inner wall of the ball socket liner 25 during the rotation process.

[0055] The crossbeam assembly 5 includes a crossbeam body 8 and a rotating motor 9. The crossbeam body 8 is arranged on the lifting execution assembly 38. The rotating motor 9 is arranged in the middle position of the crossbeam body 8. A rotating spindle 15 is provided below the rotating motor 9. A bottom fork frame 16 is provided at the end of the rotating spindle 15. A fork frame bottom circular hole 17 is provided at the end of the bottom fork frame 16.

[0056] The angle of the self-telescopic pressure-applying assembly 7 can be actively controlled by adjusting the rotation speed of the rotating main shaft 15; the adaptive torsion assembly 6 has the function of applying elastic force and automatic reset, and can overcome the elastic force of the torsion spring 11 to rotate the deflection center axis 10 when the rotating main shaft 15 rotates at high speed. After the rotating main shaft 15 stops rotating, the self-telescopic pressure-applying assembly 7 will be reset to a slightly tilted state under the elastic force of the torsion spring 11 of the adaptive torsion assembly 6.

[0057] The adaptive torsion assembly 6 includes a deflection center shaft 10, a torsion spring 11 and a deflection rod 12. The deflection center shaft 10 is rotatably arranged in the circular hole 17 at the bottom of the fork frame. End rings 18 are symmetrically provided at both ends of the deflection center shaft 10. The torsion spring 11 is provided between the end ring 18 and the bottom fork frame 16. The deflection rod 12 is fixed to the deflection center shaft 10. Square sliding rod portions 19 are symmetrically provided at both ends of the deflection rod 12.

[0058] The self-retractable pressure assembly 7 includes a grinding head 13 and a telescopic spring 14. The grinding head 13 is composed of an arc portion 20 and a sleeve portion 21. The sleeve portion 21 is engaged and slidably arranged on the square slide rod portion 19. The telescopic spring 14 is arranged between the square slide rod portion 19 and the sleeve portion 21.

[0059] The deflection rod 12 is slightly tilted in the initial state, and can control the rotation direction of the deflection rod 12 when the rotating spindle 15 rotates. On the other hand, through the combination of the elastic force of the telescopic spring 14 and the centrifugal force of the grinding head 13, the extension range of the grinding head 13 and the pressure of the grinding head 13 on the inner wall of the ball socket liner 25 can be adjusted and controlled.

[0060] like Figure 12As shown, since the rotating spindle 15 is in a vertical direction, the centrifugal force of the rotating spindle 15 is in the horizontal plane, that is, OA. OA can be divided into a force OB along the square slide portion 19 and a force OC perpendicular to the square slide portion 19. OC has no effect on the extension and retraction of the grinding head 13, while OB can overcome the elastic force of the telescopic spring 14 and make the grinding head 13 tend to extend. When the rotating speed of the rotating spindle 15 is greater, the deflection rod 12 is closer to the horizontal, and the value of OB is also greater.

[0061] like Figure 13 As shown, the ball socket liner 25 is divided into multiple areas, wherein the top opening area d does not have any solid body and does not need to be polished; the bottom area b corresponding to the top opening is ground by the rotation of the lower grinding head 13. At this time, since the centrifugal force along the square slide rod portion 19 is small, and the upper grinding head 13 does not contact the inner wall of the ball socket liner 25, the elastic force of the lower telescopic spring 14 can be increased by actively lowering the crossbeam body 8, thereby increasing the squeezing force between the grinding head 13 and the ball socket liner 25.

[0062] As the rotation speed of the rotating spindle 15 increases, the deflection rod 12 continues to tend to be horizontal. During this process, the deflection center axis 10 remains at the center of the ball socket liner 25. The lower grinding head 13 grinds area c during rotation, and the upper grinding head 13 grinds area a during rotation. Since the grinding pressure at each position is different, the grinding amount can be controlled by the residence time at that position.

[0063] During use, the user first places the ball socket body 22 between each set of transverse clamping blocks 29, with the step portion 26 located above the transverse clamping blocks 29. The user then activates the lifting motor 39 to rotate the lifting screw 40, which in turn lowers the lifting outer sleeve 42 and the crossbeam body 8 through the threaded transmission of the lifting screw 40 and the lifting nut 46.

[0064] When the lifting outer sleeve 42 descends, the pressure spring 44 is first squeezed by the wing-type cross plate 43, and the elastic force of the pressure plate return spring 32 is overcome to make the annular pressure plate 31 descend along the lifting guide bar 33. When the annular pressure plate 31 descends, it is limited by the inclined slide groove 30 and the bottom slide groove 28, which can push each group of horizontal clamping blocks 29 to slide synchronously toward the center position, thereby achieving the clamping and fixing of the circular shaft portion 27. In addition, the axial position of the ball socket body 22 can be automatically adjusted during the clamping process, so that the ball socket body 22 is finally fixed in a position coaxial with the rotating main shaft 15.

[0065] After the transverse clamping block 29 clamps the circular shaft portion 27, the annular pressure plate 31 will no longer continue to descend. At this time, if the lifting outer sleeve 42 continues to descend, the deformation of the pressure spring 44 will maintain the squeezing force of the annular pressure plate 31 on the transverse clamping block 29.

[0066] After the adaptive torsion assembly 6 and the self-retractable pressure assembly 7 are inserted into the socket liner 25, the rotation motor 9 can be started. Since the deflection rod 12 has a small tilt angle in the initial state, as the rotation speed of the rotating main shaft 15 increases, the tilt angle of the deflection rod 12 will continue to approach the horizontal position.

[0067] Since the main shaft 15 is in a vertical direction, the centrifugal force of the main shaft 15 is on the horizontal plane. Figure 12 OA in the figure can be divided into a force OB along the square slide portion 19 and a force OC perpendicular to the square slide portion 19. OC has no effect on the extension and retraction of the grinding head 13, while OB can overcome the elastic force of the telescopic spring 14 and make the grinding head 13 tend to extend. When the rotation speed of the rotating spindle 15 is greater, the deflection rod 12 is closer to being horizontal, and the value of OB is also greater.

[0068] Grinding with the grinding head 13 below Figure 13 In area b, since the centrifugal force component along the square slide rod 19 is small, and the upper grinding head 13 does not contact the inner wall of the ball socket liner 25, the elastic force of the lower telescopic spring 14 can be increased by actively lowering the crossbeam body 8, thereby increasing the squeezing force between the grinding head 13 and the ball socket liner 25.

[0069] As the rotation speed of the rotating spindle 15 increases, the deflection rod 12 continues to tend to the horizontal. During this process, the deflection center axis 10 remains at the center of the ball socket liner 25. The grinding head 13 below rotates to Figure 13 The c area in the middle is ground, and the upper grinding head 13 is grinding the Figure 13 Since the grinding pressure at each position is different, the grinding amount can be controlled by controlling the duration of the rotation speed.

[0070] After the grinding is completed, the rotating motor 9 is turned off, and the rotating spindle 15 stops rotating. The deflection rod 12 will be reset to its initial state under the elastic force of the torsion spring 11. At this time, the adaptive torsion component 6 and the self-retractable pressure component 7 can be removed from the ball socket liner 25 by raising the lifting outer sleeve 42.

[0071] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
