Description

Technical Field

[0001] The invention relates to the technical field of coupling processing, and in particular to an assembly device and an assembly method of a coupling. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part, rotates together during the transmission of motion and power, and does not disengage under normal circumstances. A cross-shaft universal coupling is a commonly used coupling, which can transmit torque and motion when there is a certain angular offset between the two shaft axes. This coupling has good spatial adaptability and compensation capabilities, and is widely used in various mechanical equipment. The cross-shaft universal coupling includes a cross shaft, a welded fork, a flange fork and a bearing. Among them, the cross shaft is used to bear axial loads, transmit torque, and allow relative rotation between the two shafts. The welded fork and the flange fork are both matched with the cross shaft to transmit torque. The bearing is used to reduce friction, improve transmission efficiency, and extend the service life of the coupling.

[0003] The patent document with publication number CN216178172U discloses a cross-axis universal coupling cross-axis assembly and fork assembly device, including a base and a single-column press and a lifting workbench arranged in the middle position of the base. A linear guide is arranged horizontally on the upper surface of the base, and a flip and rotary mechanism and a lifting tug frame are slidably arranged on both sides of the linear guide. The single-column press includes a pressure column that can move up and down, and a positioning tool corresponding to the pressure column is movably arranged on the lifting workbench. The patent can quickly realize the clamping, phase adjustment and pre-assembly of the flange fork and the cross-axis assembly through the flip and rotary mechanism. At the same time, the spline shaft assembly or the spline sleeve assembly can be quickly placed horizontally through the lifting tug frame. After the whole shaft is pre-assembled, the bearings are pressed in one by one through the single-column press, which is fast and efficient.

[0004] However, when pressing the bearing into the pre-assembled cross-shaft assembly, it is necessary to ensure that the flange fork, the welding fork and the cross-shaft are aligned with the axis line so that the bearing can be pressed in smoothly. When pressing the bearing in, the above patent document requires manual adjustment of the position of the cross-shaft to ensure that the cross-shaft, the welding fork and the flange fork are assembled in place. The labor intensity is high and the assembly accuracy cannot be guaranteed, which causes the coupling to shake easily during subsequent use, thereby affecting the service life of the coupling.

[0039] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] like Figures 1 to 7As shown, an assembly device for a coupling of the present invention comprises a frame 1, a clamping mechanism is provided on the frame 1, the clamping mechanism comprises two sets of clamping components for clamping a welding fork 41 and a flange fork 42 respectively, the clamping centers of the two sets of clamping components are coaxially arranged, the clamping component for clamping the welding fork 41 comprises a fixing seat 11 and a plurality of clamping rods 12, a side of the fixing seat 11 facing the frame 1 is provided with an installation groove 111, and the plurality of clamping rods 12 are uniformly arranged along the circumference of the installation groove 111 It is arranged in the mounting groove 111, and multiple clamping rods 12 can be synchronously moved in the direction close to or away from the axis of the mounting groove 111. The clamping assembly for clamping the flange fork 42 includes a fixed seat 13, a mounting plate 14 and multiple clamping rods 15. The multiple clamping rods 15 are evenly arranged on the mounting plate 14 along the circumference of the mounting plate 14, and the multiple clamping rods 15 can be synchronously moved in the direction close to or away from the axis of the mounting plate 14. A positioning mechanism and a pushing mechanism are also provided on the frame 1.

[0041] The positioning mechanism includes two groups of positioning components arranged relatively to each other in an upper and lower direction, each group of positioning components includes a moving seat 21, a driving member 22 for driving the moving seat 21 to move up and down, a plurality of positioning members 23 and two positioning rods 24, a plurality of positioning members 23 are evenly arranged at one end of the moving seat 21 facing the other positioning component along the circumference of the moving seat 21, and each positioning member 23 can move along the radial direction of the moving seat 21, and the width of the positioning member 23 gradually decreases in the direction away from the moving seat 21 to form a tip, the positioning rod 24 is slidably arranged on the moving seat 21, and each positioning rod 24 includes a horizontally arranged rod 1 241 and a longitudinally arranged rod 242, when the two groups of positioning components approach each other, the two positioning rods 24 in the same group of positioning components can be synchronously moved in a direction close to the axis of the moving seat 21, and in this process, the welding fork 41 and the flange fork 42 are adjusted respectively by the rod 1 241 and the rod 2 242.

[0042] Specifically, the welding fork 41 to be assembled is inserted into the mounting groove 111 on the fixing seat 11, and the welding fork 41 is clamped by a plurality of clamping rods 12. At the same time, the flange fork 42 to be assembled is placed on the side of the mounting plate 14 facing the other clamping component, and the flange fork 42 is clamped by a plurality of clamping rods 2 15. At this time, the axis of the welding fork 41 is consistent with the axis of the flange fork 42, and the cross shaft 43 is at the lower end of the space formed by the welding fork 41 and the flange fork 42 under the action of gravity, and the position of the cross shaft 43 in the horizontal direction may also be different. The deviation is caused. At this time, the driving member 1 22 drives the moving seat 21 to move in the direction close to the cross shaft 43, and drives the positioning member 23 and the positioning rod 24 provided on the moving seat 21 to move synchronously, until the rod 1 241 in the positioning rod 24 contacts the welding fork 41. At this time, the moving seat 21 continues to move, and the two positioning rods 24 in the same group of positioning components can be synchronously moved in the direction close to the axis of the moving seat 21, so that the rod 242 in the positioning rod 24 contacts the flange fork 42. In this process, the positioning member 23 is inserted into the connecting hole on the flange fork 42 and the cross shaft 4 3, and as the positioning member 23 continues to move toward the direction close to the cross shaft 43, the position of the cross shaft 43 in the horizontal direction can be adjusted by multiple positioning members 23, so that the axis of the longitudinal axis in the cross shaft 43 is consistent with the axis of the connecting hole on the flange fork head 42. In addition, in the process of the two groups of positioning components approaching each other, the rod 1 241 on the positioning rods 24 in the two groups of positioning components can be respectively contacted with the upper and lower sides of the welding fork head 41 to adjust the welding fork head 41, and at the same time, the rod 2 242 on the two positioning rods 24 in the same group of positioning components can be separately The flange yoke 42 is contacted with the left and right sides respectively, and the flange yoke 42 is adjusted. At the same time, the positioning members 23 in the two sets of positioning components are brought close to each other to adjust the longitudinal position of the cross shaft 43, so that the axis of the horizontal axis in the cross shaft 43 is consistent with the axis of the connecting hole on the welding yoke 41, and the positioning of the cross shaft 43 is completed. The axis of each axis of the cross shaft 43 is respectively consistent with the axis of the connecting hole on the welding yoke 41 and the flange yoke 42, so as to ensure the smooth assembly of the subsequent bearing 44, reduce the additional wear and vibration caused by the misalignment of the axis, and thus increase the service life of the coupling.

[0043] The pushing mechanism includes two groups of pushing components arranged opposite to each other on the left and right sides. Each group of pushing components includes a pushing plate 31, a driving member 32 for driving the pushing plate 31 to move, and a plurality of clamping members 33 for clamping the bearing 44. Each clamping member 33 is an elastic telescopic structure.

[0044] Specifically, after the welding fork 41 and the flange fork 42 are clamped by the clamping mechanism, and the cross shaft 43 is positioned by the positioning mechanism, the push plate 31 is driven by the driving member 32 to move in the direction close to the cross shaft 43, and the bearings 44 clamped by the multiple clamping members 33 are driven to move synchronously until the push plate 31 contacts the welding fork 41. At this time, the bearings 44 on both sides are completely pushed into the connecting holes on the welding fork 41, and then the two groups of clamping components are synchronously rotated 90 degrees around the clamping center to drive the welding fork 41, the flange fork 42 and the cross shaft 43 to synchronously rotate 90 degrees, and then the other two bearings 44 are installed into the connecting holes on the flange fork 42 through the pushing mechanism, so as to realize the assembly process of the coupling. Among them, the rotation of the clamping component is a prior art and will not be repeated here.

[0045] It should be noted that a plurality of slide grooves 211 are provided at opposite ends of the moving seat 21 in the two groups of positioning assemblies. The plurality of slide grooves 211 are evenly spaced along the circumference of the moving seat 21, and each slide groove 211 is arranged along the radial direction of the moving seat 21. The plurality of positioning members 23 are respectively slidably arranged in the plurality of slide grooves 211, and a spring 1 is connected between the slide grooves 211 to drive the positioning member 23 to reset.

[0046] In some embodiments, the tip of the positioning member 23 has two inclined surfaces, with the inner side being the direction toward the axis of the movable seat 21. When the movable seats 21 in the two groups of positioning assemblies approach each other, the tip of the positioning member 23 can be inserted into the connecting hole on the flange fork 42, and the outer inclined surface contacts the flange fork 42, and the inner inclined surface contacts the cross shaft 43.

[0047] Specifically, Figures 1 to 4 As shown, when the moving seat 21 is driven by the driving member 22 to move in the direction close to the cross shaft 43, the positioning member 23 arranged in the slide groove 211 will be driven to move synchronously until the tip of the positioning member 23 is inserted into the connecting hole of the flange fork head 42, and as the moving seat 21 continues to move, the inclined surface facing outward can contact the flange fork head 42, and the inclined surface facing inward can contact the cross shaft 43, so that the position of the cross shaft 43 in the horizontal direction can be adjusted by the movement of the positioning member 23, so that the axis of the longitudinal axis in the cross shaft 43 is consistent with the axis of the connecting hole on the flange fork head 42. At the same time, by bringing the positioning members 23 in the two groups of positioning assemblies closer to each other, the position of the cross shaft 43 in the longitudinal direction can be adjusted, so that the axis of the horizontal axis in the cross shaft 43 is consistent with the axis of the connecting hole on the welding fork head 41, so as to realize the positioning of the cross shaft 43.

[0048] In some embodiments, two sides of the moving seat 21 are respectively provided with a second slide groove 212 for installing the positioning rod 24. The interior of the second slide groove 212 is in the shape of an inclined surface, with the end facing the center of the frame 1 as the upper end of the moving seat 21. The inclined surface gradually inclines from the upper end to the lower end of the moving seat 21 toward the direction close to the axis of the moving seat 21. The positioning rod 24 slides along the inclined surface and cooperates with the second slide groove 212, and a spring 2 is connected between the positioning rod 24 and the side wall of the second slide groove 212 to drive the positioning rod 24 to reset.

[0049] Specifically, Figures 2 to 7 As shown, when the moving seat 21 is driven by the driving member 1 22 to move in the direction close to the cross shaft 43, the positioning rod 24 arranged in the second slide groove 212 will be driven to move synchronously until the rod member 1 241 in the positioning rod 24 contacts the welding fork 41. At this time, the moving seat 21 continues to move, and the rod member 1 241 is blocked by the welding fork 41 and stops moving. Under the action of the inclined surface in the second slide groove 212, the positioning rod 24 moves in the direction close to the axis of the moving seat 21 until the rod member 242 in the positioning rod 24 contacts the flange fork 42. After the welding fork 41 and the flange fork 42 are clamped by two sets of clamping components respectively, If the welding fork 41 and the flange fork 42 are tilted, the two groups of positioning components can be brought closer to each other so that the rod 1 241 on the positioning rods 24 in the two groups of positioning components can contact the upper and lower sides of the welding fork 41 respectively, so as to adjust the welding fork 41 and adjust the welding fork 41 to a horizontal state. At the same time, the two positioning rods 24 in the same group of positioning components can be brought closer to each other and the rod 2 242 on the two positioning rods 24 in the same group of positioning components can contact the left and right sides of the flange fork 42 respectively, so as to adjust the flange fork 42 and adjust the flange fork 42 to a horizontal state, so as to ensure the smooth assembly of the subsequent bearing 44.

[0050] It should be noted that the rod member 242 is an elastic telescopic structure, so that the length of the rod member 242 can be adapted according to the distance between the moving seat 21 and the welding fork 41. When the rod member 1 241 in the positioning rod 24 contacts the welding fork 41 and the rod member 242 contacts the flange fork 42, if the moving seat 21 needs to continue to move toward the direction close to the cross axis 43, the rod member 242 will be forced to shrink to adapt to the distance between the moving seat 21 and the welding fork 41. After the positioning is completed, the rod member 242 will automatically return to its original length during the process of resetting the moving seat 21 driven by the driving member 1 22.

[0051] In some embodiments, a plurality of slide grooves 311 are provided on one side of the push plate 31 facing the center of the frame 1. The plurality of slide grooves 311 are evenly spaced along the circumference of the push plate 31. Each slide groove 311 is arranged along the radial direction of the push plate 31. The plurality of clamping members 33 are respectively slidably arranged in the plurality of slide grooves 311.

[0052] Specifically, Figures 2 to 7 As shown, the push plate 31 is driven by the driving member 2 32 to move toward the direction close to the cross shaft 43, and the bearings 44 clamped by the multiple clamping members 33 are driven to move synchronously. When the end of the clamping member 33 away from the push plate 31 contacts the welding fork 41 or the flange fork 42, the clamping member 33 will be forced to shrink into the slide groove 3 311 until the push plate 31 contacts the welding fork 41 or the flange fork 42. At this time, the bearing 44 is completely pushed into the connecting hole on the welding fork 41 or the flange fork 42, thereby realizing the assembly process of the coupling.

[0053] In some embodiments, an adjustment plate 34 is provided on one side of the push plate 31 facing the center of the frame 1 . The adjustment plate 34 is a telescopic structure so that the thickness of the adjustment plate 34 can be adjusted.

[0054] Specifically, Figure 2 , Figure 5 and Figure 7 As shown, for some couplings that require the bearing 44 to be pushed into the connecting hole by a set distance, the thickness of the adjusting plate 34 can be adjusted to the required pushing distance, so that when the push plate 31 moves toward the direction close to the welding fork 41 or the flange fork 42, the clamped bearing 44 can be pushed into the connecting hole by a set distance through the setting of the adjusting plate 34, thereby improving the applicability of the equipment.

[0055] In some embodiments, the pushing assembly also includes a driving member three for driving the pushing plate 31 to rotate. When the bearing 44 needs to be pushed into the connecting hole, the pushing plate 31 is driven to rotate by the driving member three, and the bearings 44 clamped by multiple clamping members 33 are driven to rotate synchronously. While the bearing 44 rotates, the pushing plate 31 is driven by the driving member two 32 to move toward the direction close to the cross shaft 43, and the bearing 44 is driven to move synchronously until the bearing 44 is completely pushed into the connecting hole, and the rotation and pushing process is completed. Through the rotation and pushing of the bearing 44, the friction and wear between the bearing 44 and the welding fork 41, the flange fork 42 and the cross shaft 43 can be reduced.

[0056] like Figures 1 to 7 As shown, the present invention also provides a method for assembling a coupling using the above-mentioned assembly device, which specifically includes the following steps:

[0057] S1. Clamping: Clamp the welding fork 41 and the flange fork 42 respectively by two sets of clamping components, so that the axes of the welding fork 41 and the flange fork 42 are consistent;

[0058] S2, positioning: the moving seat 21 is driven to move by the driving member 22. During this process, the positioning member 23 can be inserted into the gap between the flange fork 42 and the cross shaft 43 to adjust the position of the cross shaft 43 in the horizontal direction so that the axis of the longitudinal axis in the cross shaft 43 is consistent with the axis of the connecting hole on the flange fork 42. At the same time, by bringing the two positioning components closer to each other, the position of the cross shaft 43 in the longitudinal direction is adjusted so that the axis of the horizontal axis in the cross shaft 43 is consistent with the axis of the connecting hole on the welding fork 41, so that the axis of each axis in the cross shaft 43 is consistent with the axis of the corresponding connecting hole, which is convenient for the subsequent assembly of the bearing 44;

[0059] S3, adjustment: when the two groups of positioning components are approaching each other, the positioning rods 24 in the two groups of positioning components will be driven to approach each other, and the two positioning rods 24 in the same group of positioning components will be synchronously moved in the direction close to the axis of the moving seat 21, so that the welding fork 41 and the flange fork 42 can be adjusted through the contact between the rod 1 241 and the welding fork 41, and the contact between the rod 242 and the flange fork 42, so as to further improve the assembly accuracy;

[0060] S4, assembly: push the bearing 44 into the connection holes on the welding fork 41 and the flange fork 42 to complete the assembly of the coupling.

[0061] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
