[0023] The utility model will be further described below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, the side bearing disassembly and assembly device of one embodiment of the utility model comprises a disassembly and assembly platform 1, a transfer mechanical arm 2, a detection platform 3 and a detection mechanical arm 4. The disassembly and assembly platform 1 and the detection platform 3 are respectively arranged on both sides of the transfer mechanical arm 2, and the transfer mechanical arm 2 and the detection mechanical arm 4 are respectively arranged on both sides of the detection platform 3. An electromagnet 5 is arranged at one end of the transfer mechanical arm 2, and a camera 6 is arranged at one end of the detection mechanical arm 4. The disassembly and assembly platform 1 comprises a frame 11, and a lifting assembly 12 and a clamping assembly 13 are arranged on the frame 11. The clamping assembly 13 is arranged above the lifting assembly 12, and the clamping assembly 13 comprises a pair of clamping arms 131 for clamping the side bearing body 71. A spring is arranged inside the side bearing body 71, and the side bearing body 71 is a composite part of rubber and metal, and the side bearing seat 72 is a steel part, so the side bearing body 71 and the side bearing seat 72 can be adsorbed by the electromagnet 5, and the transfer of the side bearing 7 is realized by the transfer mechanical arm 2. The camera 6 is a 3D camera, which can perform structured light detection on the assembled side bearing 7 to determine whether the side bearing 7 is assembled in place.

[0025] The disassembly and assembly platform 1 can realize the disassembly and assembly of the side bearing 7 through the cooperation of the lifting component 12 and the clamping component 13. The transfer robot arm 2 can move the side bearing 7 to the disassembly and assembly platform 1 with the help of the electromagnet 5 and transfer the assembled side bearing 7 to the inspection platform 3. The inspection robot arm 4 then uses the camera 6 to perform an appearance inspection on the assembled side bearing 7. After the inspection is completed, the transfer robot arm 2 will separate the qualified products from the unqualified products, thereby realizing the disassembly, assembly and inspection of the side bearing 7, reducing labor intensity and improving work efficiency.

[0026] The disassembly process of the side bearing 7 is as follows: the transfer robot arm 2 places the side bearing 7 to be disassembled on the lifting assembly 12, the lifting assembly 12 lifts the side bearing 7 to the disassembly position, the two clamping arms 131 move toward each other, clamp the side bearing body 71 and deform it, and the side bearing body 71 and the side bearing seat 72 change from an interference fit to a clearance fit. At this time, the lifting assembly 12 causes the side bearing seat 72 to descend, and the side bearing body 71 is separated from the side bearing seat 72. Subsequently, the two clamping arms 131 move in opposite directions, and the side bearing body 71 is separated from the clamping arms 131. The disassembled side bearing body 71 can be removed by using the transfer robot arm 2.

[0027] The assembly process of the side bearing 7 is as follows: the transfer robot arm 2 is used to place the side bearing seat 72 and the side bearing body 71 to be assembled on the lifting assembly 12, the lifting assembly 12 raises the side bearing seat 72 and the side bearing body 71 to the set position, the two clamping arms 131 move towards each other, clamp the side bearing body 71 and deform it, at this time the lifting assembly 12 continues to raise the side bearing seat 72 to press the side bearing body 71 into the side bearing seat 72, then the two clamping arms 131 move in the opposite direction to release the side bearing body 71 to fix the side bearing body 71 in the side bearing seat 72, the lifting assembly 12 lowers the assembled side bearing 7, and the transfer robot arm 2 transfers the assembled side bearing 7 to the inspection table 3 for inspection.

[0028] like Figure 2 and Figure 3 As shown, the clamping assembly 13 further includes a lead screw 132, the threads at both ends of the lead screw 132 have opposite rotation directions, and two clamping arms 131 are respectively arranged at both ends of the lead screw 132. The clamping arms 131 are threadedly connected to the lead screw 132, and since the threads at both ends of the lead screw 132 have opposite rotation directions, when the lead screw 132 rotates, the movement directions of the two clamping arms 131 are also opposite, so that the two clamping arms 131 can move closer to or farther from each other.

[0029] Furthermore, the clamping assembly 13 further includes a first guide rail 133 and a first slider 134 disposed on the first guide rail 133. The first guide rail 133 is disposed in parallel with the lead screw 132, and the clamping arm 131 is connected to the first slider 134. In order to deform the side bearing body 71, the clamping arm 131 needs to exert a larger clamping force. By disposing the clamping arm 131 on the first slider 134, the stability of the clamping arm 131 and the structural reliability of the clamping assembly 13 can be improved.

[0030] like Figure 3 As shown, the first guide rail 133 and the lead screw 132 are both arranged horizontally, and the first guide rail 133 is located below the lead screw 132. The first guide rail 133 is closer to the force point of the clamping arm 131, which greatly reduces the shear force on the lead screw 132 and effectively protects the lead screw 132.

[0031] like Figure 4As shown, the frame 11 is also provided with a reduction motor 135, which is connected to the lead screw 132. The reduction motor 135 drives the lead screw 132 to rotate and can provide a large torque.

[0032] like Figure 4 and Figure 5 As shown, the lifting assembly 12 includes a cylinder 121, a bearing platform 122, a second guide rail 123 and a second slider 124. One end of the cylinder 121 is fixed to the frame 11, and the other end of the cylinder 121 is connected to the bearing platform 122. The second slider 124 is slidably disposed on the second guide rail 123 and connected to one side of the bearing platform 122. The second guide rail 123 is vertically disposed. The cylinder 121 can drive the bearing platform 122 to move up and down, and the second guide rail 123 and the second slider 124 can keep the bearing platform 122 straight up and down, thereby improving the stability of the bearing platform 122.

[0033] like Figure 3 As shown, a positioning plate 125 is also provided on the top surface of the carrier 122, and the cross section of the positioning plate 125 is stepped. When the transfer robot 2 places the side bearing 7 on the positioning plate 125, the stepped structure of the positioning plate 125 can limit one side of the side bearing 7, so that the side bearing 7 is accurately positioned to smoothly carry out subsequent disassembly or assembly operations.

[0034] like Figure 3 As shown, the frame 11 is also detachably provided with a pad 126, which is arranged just above the lifting platform and between the two clamping arms 131. When the disassembling and assembling platform 1 is working, the side bearing body 71 will impact and squeeze the pad 126, so the pad 126 can protect the frame 11. The pad 126 is fixed to the frame 11 with bolts, which is also convenient when the pad 126 needs to be replaced.

[0035] The transfer robot 2 and the detection robot 4 are both six-axis robots with high flexibility, so that the transfer robot 2 can meet the needs of moving the side bearing 7, and the detection robot 4 can also enable the camera 6 to detect the side bearing 7 on the detection platform 3 at a variety of different angles, so that the detection results are accurate and reliable.

[0036] like Figure 4 and Figure 5 As shown, a limiting protrusion 1311 is provided on the end surface of the clamp arm 131, and the limiting protrusion 1311 is in a long strip shape and is horizontally arranged at the top of the end surface. When assembling the side bearing 7, the bearing platform 122 will lift the side bearing seat 72, and the side bearing seat 72 will lift the side bearing body 71 upward. The limiting protrusion 1311 on the clamp arm 131 can limit the side bearing body 71, preventing the side bearing body 71 from detaching from the clamp arm 131, and ensuring the smooth assembly of the side bearing 7.

[0037] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
