[0002] The universal joint of engineering machinery is usually used in low-speed and high-load working conditions. The universal joint of engineering machinery is used in conjunction with a wing-shaped sleeve and a cross shaft. Among them, the wing-shaped sleeve has multiple needle rollers, shaft end washers and needle roller washers inside.

[0003] At present, the processing of airfoil sleeves is usually completed on machine tools by turning the main shaft neck, drilling the center hole and turning the end plane. During installation, the operator first places the shaft end gasket and needle roller gasket at the bottom of the center hole, then applies grease to the inner raceway of the center hole, and places the needle rollers close to the grease at the installation location in turn. In this way, the workload is huge, resulting in the inability to effectively control the installation dimensions of the shaft end gasket and needle roller gasket. It is often the case that multiple shaft end gaskets or needle roller gaskets are installed, and the shaft end gasket and the needle roller gasket are in the opposite position, resulting in unsatisfactory assembly effect and low assembly efficiency. Therefore, it is very necessary to improve the installation efficiency of the airfoil sleeve and ensure the processing quality of the airfoil sleeve.

[0004] At present, the existing processing and assembly of wing-shaped bushings on the market is that the operator places the shaft end gasket and the needle roller gasket in sequence at the bottom of the center hole. Since the shaft end gasket and the needle roller gasket cannot be accurately positioned during installation, it is easy to cause the installation dimensions of the shaft end gasket and the needle roller gasket not to meet the use requirements during the assembly process, thereby affecting the operating state of the needle roller, resulting in the quality of the engineering machinery universal joint not meeting the use requirements.

The second gasket is sleeved in the second installation area B through the second center hole, and the end of the second elastic component B1 away from the assembly axis is abutted against the inner wall of the second center hole.

[0051] In this embodiment, a positioning mechanism 1 is provided, and the positioning mechanism 1 is used to position the first gasket and the second gasket. A first mounting area A and a second mounting area B are formed on the positioning mounting portion 12 on the side where the assembly axis is away from the first positioning mounting plate 11, and the outer diameter of the first mounting area A is greater than the outer diameter of the second mounting area B, and the first mounting area A is arranged close to the side where the first positioning mounting plate 11 is located, and the second mounting area B is arranged away from the side where the first positioning mounting plate 11 is located, so that the first gasket and the second gasket can be assembled on the positioning mounting portion 12 at the same time, that is, the first gasket is assembled in the first mounting area A, and the second gasket is assembled in the second mounting area B.

[0052] Furthermore, the first gasket is a needle roller gasket, and the middle part of the first gasket has a first center hole extending axially along the assembly axis. The first gasket can be sleeved on the first installation area A through the first center hole, and the first installation area A is provided with a first elastic component A1 on the outer peripheral side, so that the end of the first elastic component A1 away from the side where the assembly axis is located abuts against the inner side wall of the first center hole, thereby completing the fastening of the first gasket to the first installation area A; the second gasket is an axial end gasket, and the middle part of the second gasket has a second center hole extending axially along the assembly axis.

In the present application, the diameter of the first center hole is larger than the diameter of the second center hole, and the outer diameter of the second gasket is larger than the diameter of the first center hole. Through the above-mentioned arrangement, after the first gasket is assembled in the first installation area A, the second gasket can be assembled in the second installation area B, so that the installation position of the first gasket will not be wrong during the assembly process, thereby further improving the assembly efficiency; furthermore, when the first gasket and the second gasket need to be installed on the wing-shaped sleeve, the first gasket can be moved downward, and then the first gasket can drive the second gasket to be installed on the bottom of the center hole of the wing-shaped sleeve, so that the first gasket and the second gasket can be accurately installed.

[0053] Through the above arrangement, the shaft end gasket and the needle roller gasket can be positioned more tightly at the same time during the assembly process, and there is no need to design a more complicated structure to limit the shaft end gasket and the needle roller gasket.

[0054] In some embodiments, the positioning mechanism 1 further includes a first positioning unit, the first positioning unit further includes a first driving component 131 and a guide sleeve 132 located on one side of the first driving component 131, the first driving component 131 is fixed on the first positioning mounting plate 11, and the guide sleeve 132 is sleeved on the assembly shaft;

[0055] The first driving component 131 is used to push the guide sleeve 132 to reciprocate between the first position and the second position along the axial direction of the assembly shaft; wherein, when the guide sleeve 132 is located at the first position, the guide sleeve 132 is arranged away from the positioning mounting portion 12; when the guide sleeve 132 moves from the first position toward the second position, the guide sleeve 132 contacts the first gasket and forces the first gasket and the second gasket to be separated from the positioning mounting portion 12.

[0056] Furthermore, the first positioning and mounting plate 11 includes a main body, a first side portion and a second side portion, wherein the first side portion and the second side portion are arranged at opposite ends of the main body, and the first side portion and the second side portion are arranged perpendicular to the main body;

[0057] The first driving component 131 includes a first cylinder and a first pushing block, one end of the assembly shaft is fixed to the first side portion, the first cylinder is fixed to the second side portion, the output shaft of the first cylinder passes through the second side portion and is fixedly connected to the first pushing block, and a plurality of support columns extend outward from the other end of the first pushing block, each of the support columns passes through the first side portion and is fixedly connected to the guide sleeve 132.

[0058] In this embodiment, the first drive component 131 can be a cylinder or an electric cylinder, and the present application prefers the first cylinder. The main body of the first drive component 131 is detachably fixed on the first positioning mounting plate 11, and the output shaft of the first drive component 131 is fixedly connected to the guide sleeve 132 and is coaxially arranged with the assembly axis, and the end of the output shaft of the first drive component 131 is arranged toward the side where the positioning mounting portion 12 is located, and the guide sleeve 132 is sleeved on the assembly shaft.

[0059] Further, the first positioning mounting plate 11 has a main body, which can be installed on other equipment to realize that the positioning mechanism 1 can be used in conjunction with other equipment. The first side edge and the second side edge are vertically extended from the opposite ends of the main body, and one end of the assembly shaft is fixed on the first side edge and is arranged away from the second side edge. The first driving assembly 131 includes a first cylinder and a first push block, the first cylinder is fixed on the second side edge and is arranged away from the first side edge, so that the output shaft of the first cylinder passes through the second side edge and is fixedly connected to the first push block, and the other end of the first push block extends outward with a plurality of support columns, each of which passes through the first side edge and is fixedly connected to the guide sleeve 132. In the present application, the first cylinder pushes the first push block to drive the guide sleeve 132 to reciprocate between the first position and the second position along the axial direction of the assembly shaft, wherein when the guide sleeve 132 is located in the first position, the guide sleeve 132 is arranged away from the positioning mounting portion 12, and the positioning installation of the first gasket and the second gasket can be completed at this time. When the guide sleeve 132 moves from the first position toward the second position, the guide sleeve 132 contacts the first gasket and forces the first gasket to contact and abut against the second gasket to be separated from the positioning and mounting portion 12, thereby being installed at the bottom of the center hole of the airfoil sleeve.

[0060] In some embodiments, a step is formed at one end of the first installation area A close to the first positioning installation plate 11, and when the first gasket is sleeved on the first installation area A, one end of the first gasket abuts against the step surface of the step;

[0061] The value of the ratio K1 between the axial distance of the first installation area A along the assembly axis and the thickness of the first gasket is: 0.8≤K1≤1.1.

[0062] Furthermore, a ratio K2 of the distance of the second installation area B along the axial direction of the assembly axis to the thickness of the second gasket is set to: 1≤K1≤1.3.

[0063] In this embodiment, through the above arrangement, when it is necessary to accurately sleeve the first gasket on the first installation area A of the positioning installation part 12, the first center hole of the first gasket can be manually aligned with the positioning installation part 12 of the assembly axis, and then the first gasket is pushed to move along the axial direction of the assembly axis toward the side where the positioning installation part 12 is located, so as to force the first center hole of the first gasket to be sleeved on the outer periphery of the first installation area A, or the first gasket is aligned with the above structure and installed on the positioning installation part 12 by means of a mechanical arm or the like. In this application, since the ratio K1 between the distance of the first installation area A along the axial direction of the assembly axis and the thickness of the first gasket is 0.8≤K1≤1.1, when the first gasket is sleeved on the first installation area A and one end of the first gasket contacts the step surface of the step, the first gasket can be accurately sleeved on the first installation area A, and when the first gasket and the second gasket are assembled, the first gasket will reduce the influence on the position accuracy of the second gasket during the downward movement; furthermore. The ratio K2 of the distance of the second installation area B along the axial direction of the assembly axis and the thickness of the second gasket is: 1≤K1≤1.3, so as to achieve precise positioning of the first gasket and the second gasket on the positioning installation part 12, and then further reduce the impact on the installation dimensions of the first gasket and the second gasket during the assembly process, so as to achieve effective control of the installation dimensions of the first gasket and the second gasket and improve the quality of the engineering machinery universal joint.

[0064] In some embodiments, the elastic component includes a pressing member and an elastic member, the first elastic component A1 includes a pressing member and an elastic member, a surface where the outer periphery of the first installation area A is located is concavely provided with a receiving groove, the pressing member is located in the receiving groove, and the pressing member is partially exposed at the open end of the receiving groove, one end of the elastic member is fixed to the bottom of the receiving groove, and the other end of the elastic member is fixed to the pressing member;

[0065] There are a plurality of first elastic components A1 , which are evenly distributed around the outer edge of the positioning and mounting portion 12 .

[0066] In this embodiment, the present application preferably provides three accommodating grooves, each of which is symmetrically arranged at intervals along the outer circumference of the positioning and mounting portion 12, so that each group of elastic components is symmetrically fixed in each accommodating groove.

[0067] Through the above arrangement, during the installation of the first gasket, the force applied to each clamping member by at least a portion of the inner circumference of the inner side wall of the first center hole of the first gasket will drive the elastic member to move inward, thereby putting the elastic member in a compressed state. Furthermore, the elastic member can apply a reaction force to the clamping member, so that the clamping member abuts against the inner side wall of the first center hole, so as to achieve extrusion of the inner wall of the first gasket and achieve precise positioning of the first gasket. In the present application, the accommodating grooves can also be set to two, three, five or more than six, and the present application is not limited thereto. Among them, the elastic member can be an elastic ball or a compression spring, and the clamping member can be a rolling ball, etc. In the present application, the first elastic component A1 can also be set to other implementable structures, and the present application is not limited thereto.

[0068] In this embodiment, through the above-mentioned structural setting, the three accommodating grooves are evenly distributed along the outer edge of the assembly axis on the first installation area A. When the first gasket is sleeved on the first installation area A through the first center hole, the force (i.e., the force) applied to each clamping member is more evenly distributed, further realizing the precise positioning of the first gasket.

[0069] In this embodiment, the three pressing members are of the same shape and size, so as to facilitate rapid processing and reduce the manufacturing cost of the elastic member.

[0070] In this embodiment, the structure of the second elastic component B1 is the same as that of the first elastic component A1, and the second elastic component B1 is connected to the second mounting area B in the same manner, which is not described in this application.
