Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hinge and articulated joint repair tools, in particular to a hinge and articulated joint repair device. Background Art
[0002] The articulated joint is a key component connecting the front and rear frames of an articulated truck, playing a vital role in connection and support. Due to its complex operating environment, the bearing, as a vulnerable component of the articulated joint, often suffers from increased wear due to harsh working conditions or prolonged use, resulting in the need for frequent repair or replacement. In some cases, when the articulated joint's bearing seat is excessively worn, traditional replacement and repair methods may increase the repair cost and downtime of the articulated truck. To reduce repair costs and downtime, a feasible solution is to use laser repair technology. This technology repairs the bearing seat through laser welding or laser cladding to restore it to the designed size and surface condition. However, during the laser welding process of the articulated joint and the bearing ring, the staff needs to use a bracket to control the concentricity between the bearing ring and the articulated joint. The adjustment process is relatively cumbersome, and the staff needs to adjust the bracket multiple times to ensure the correct alignment of the articulated joint and the bearing ring. This not only increases the repair time, but also increases the concentricity error, resulting in the concentricity of the repaired bearing seat not meeting the standard. Utility Model Content

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0018] See also Figure 1-5 The present invention provides an embodiment of a hinge joint maintenance device, comprising a chassis 1 and an I-beam 2 fixed at the top of the chassis 1, and a double-roller support for supporting the hinge joint is installed on one side of the top of the I-beam 2, the double-roller support is a vertical plate 3 fixed to one side of the top of the I-beam 2, and two main rollers 4 symmetrically rotatably installed on the outer wall of one side of the vertical plate 3. The hinge joint to be laser welded and repaired is placed on the two main rollers 4 and its placement is ensured to be stable.
[0019] Two symmetrical right-angle arms 6 are fixed to the outer wall of one side of the I-beam 2, and an inverted T-shaped slide 8 is slidably installed on the top of the two right-angle arms 6, and a screw electric lifting module 10 is installed on the outer wall of one side of the inverted T-shaped slide 8. A connecting plate 9 is installed at the movable end of the screw electric lifting module 10, and two symmetrical auxiliary rollers 11 are installed on the outer wall of the connecting plate 9 close to the side of the I-beam 2. An X-axis horizontal pushing unit 7 for pulling the inverted T-shaped slide 8 for horizontal sliding is installed on the top of the I-beam 2. A control panel 5 is installed on one side of the surface of the I-beam 2, and the output end of the control panel 5 is electrically connected to the X-axis horizontal pushing unit 7 and the input end of the screw electric lifting module 10;
[0020] By adjusting the action positions of the X-axis push unit 7 and the lead screw electric lifting module 10, it is possible to flexibly cope with various sizes and structures of hinge joints and bearing rings without having to redesign the support structure for each case;
[0021] The main roller 4 and auxiliary roller 11 are both made of stainless steel. The stainless steel main roller 4 and auxiliary roller 11 can withstand large forces and pressures without being easily deformed or damaged, thus ensuring stability and accuracy during the repair process.
[0022] A dovetail track is fixed to the top of the right-angle arm 6, and a sliding sleeve that slides with the dovetail track is installed at the bottom of the inverted T-shaped slide 8. The X-axis push unit 7 is an electric push rod installed at the bottom of the I-beam 2. A boss is installed at the top of the piston rod of the electric push rod, and the top of the boss is fixedly connected to the bottom of the inverted T-shaped slide 8.
[0023] The X-axis push unit 7 uses an electric push rod, which pulls the inverted T-shaped slide 8, connecting plate 9, auxiliary roller 11 and other workpieces to move horizontally. During this process, the guide rail at the top of the right-angle arm 6 allows the inverted T-shaped slide 8 to be pulled stably, so that the repaired bearing ring and hinge joint maintain a stable position during the welding or cladding process, which helps to control the welding quality and the consistency of the repair effect.
[0024] The screw electric lifting module 10 includes a lower convex plate 1001, an upper convex plate 1002 and a servo motor 1003 installed on the outer wall of one side of the inverted T-shaped slide 8, a one-way screw 1004 is rotatably installed between the lower convex plate 1001 and the upper convex plate 1002, and a nut pair 1005 is installed at the threaded part of one end of the surface of the one-way screw 1004. The outer wall of one side of the nut pair 1005 is fixedly connected to the back of the connecting plate 9, and the top of the one-way screw 1004 is fixedly connected to the output end of the servo motor 1003 through a coupling. The staff turns on the servo motor 1003 through the control panel 5 to work, and the rotational power of the servo motor 1003 is transmitted to the one-way screw 1004, and the one-way screw 1004 drives the nut pair 1005, the connecting plate 9 and the auxiliary roller 11 to rise and fall, so as to control the height of the bearing ring, thereby ensuring that the alignment accuracy and concentricity of the bearing ring and the hinge joint meet the welding requirements.
[0025] When the embodiment of the present application is in use, the staff first places the hinge joint to be laser welded and repaired on the two main rollers 4 and ensures that it is placed stably. Then the staff places the bearing ring on the two auxiliary rollers 11 so that the hinge joint and the bearing ring are opposite to each other. After the two workpieces are arranged, the staff turns on the X-axis horizontal push unit 7 and the screw electric lifting module 10 through the control panel 5 to work, and controls the vertical height of the connecting plate 9 and the auxiliary roller 11 through the screw electric lifting module 10 until the hinge joint and the bearing ring are in a concentric state. The inverted T-shaped slide 8, the connecting plate 9 and the auxiliary roller 11 are pulled by the X-axis horizontal push unit 7. And the workpieces such as the bearing ring are moved horizontally until the bearing ring is mounted on the hinge joint, and then the staff can use the laser welding device to perform laser welding on the hinge joint and the bearing ring. The device can adjust the horizontal position and vertical height of the auxiliary roller 11 and the bearing ring through the precise control of the X-axis horizontal pushing unit 7 and the screw electric lifting module 10, ensuring that the alignment accuracy and concentricity of the bearing ring and the hinge joint meet the design requirements, so that the size and shape of the repaired bearing seat meet the standard, and the automatic adjustment function of the X-axis horizontal pushing unit 7 and the screw electric lifting module 10 makes the adjustment process faster and more accurate, reducing the possibility of human operation errors.
