Description

Technical Field

[0002] A wheel stopper, also known as a brake or parking brake, is a device used to prevent a vehicle from accidentally sliding after it has stopped. The shell of the wheel stopper includes a supporting shell and a contact plate. The supporting shell contacts the ground through bolts or friction. An arc-shaped mounting groove is provided at the upper end of the supporting shell. The contact plate is fixedly connected to the mounting groove by welding. When in use, the contact plate is placed in a position in contact with the wheel. In order to ensure the braking performance of the wheel stopper, the shell of the wheel stopper is generally made of metal, and an anti-skid plate is adhered to the lower end of the supporting shell and the upper end of the contact plate.

[0003] In the prior art, when welding the wheel stopper shell, the installation groove at the upper end of the support shell is generally polished first, and then the lower end of the contact plate is polished, and then the contact plate is placed in the installation groove of the support shell, and finally the worker uses a hand-held welding gun to weld.

[0036] Specifically, several fourth electric telescopic rods 311 on the side of the fixed rod 39 drive the grinding plate 312 to contact the supporting shell and grind along the mounting groove. During grinding, the pressure sensor 313 can control the side of the grinding plate 312 to fit the supporting shell for grinding. At the same time, the controller can record the moving trajectory of the fixed rod 39, thereby obtaining the accurate trajectory of the mounting groove.

[0037] In this embodiment, a welding mechanism 4 for welding the polished shell is disposed at the upper end of the main body plate 1 .

[0038] The welding mechanism 4 includes two first limit blocks 41 slidably matched with the third limit groove 32, the upper ends of the two first limit blocks 41 are respectively fixedly connected with the fifth electric telescopic rod 42, the telescopic ends of the two fifth electric telescopic rods 42 are respectively fixedly connected with the sixth electric telescopic rod 43, the telescopic ends of the two sixth electric telescopic rods 43 are respectively fixedly connected with the third fixed body 44, the inner side surfaces of the two third fixed bodies 44 are respectively provided with fourth empty grooves 45, welding guns 47 are respectively rotatably arranged in the two fourth empty grooves 45, the sides of the two third fixed bodies 44 are respectively fixedly connected with the sixth motor 46, and the transmission shaft ends of the two sixth motors 46 are respectively fixedly connected to the sides of the welding gun 47.

[0039] Specifically, the two sixth electric telescopic rods 43 drive the welding gun 47 to move to a position close to the weld, and at the same time the sixth motor 46 drives the welding gun 47 to rotate to align with the weld, so as to weld the contact plate and the support shell with high efficiency. By moving according to the trajectory of the fitting surface, the quality of welding by the welding gun 47 can be ensured.

[0040] In this embodiment, a second clamping mechanism 5 for clamping the supporting shell is disposed at the upper end of the main body plate 1 .

[0041] The second clamping mechanism 5 includes a second limit block 51 that is slidably matched with the first limit groove 22. The second limit block 51 is arranged with the first threaded rod 23 by threaded matching. The thread on the side of the first threaded rod 23 consists of threads with opposite rotation directions at both ends. The upper end of the second limit block 51 is fixedly connected to the seventh electric telescopic rod 52, and the telescopic end of the seventh electric telescopic rod 52 is fixedly connected to the double-axis electric telescopic rod 53. The telescopic ends of the double-axis electric telescopic rod 53 are respectively fixedly connected to connecting plates 54, and the inner sides of the two connecting plates 54 are respectively fixedly connected to extrusion plates 55.

[0042] Specifically, the shell is placed above the double-axis electric telescopic rod 53 with the installation groove facing upward, and then the double-axis electric telescopic rod 53 is retracted. The double-axis electric telescopic rod 53 drives the extrusion plate 55 to squeeze the side of the supporting shell through the connecting plate 54, thereby fixing the supporting shell.

[0043] When in use, the main body plate 1 is placed on a horizontal plane, and then the contact plate and the support shell are fixed first. When fixing the support shell, the shell is placed above the double-axis electric telescopic rod 53 in a manner with the mounting slot facing upward. Then the double-axis electric telescopic rod 53 is retracted, and the double-axis electric telescopic rod 53 drives the extrusion plate 55 to squeeze the side of the support shell through the connecting plate 54, thereby fixing the support shell, and starting the third motor 212. The third motor 212 drives the second threaded rod 211 to rotate, and the second threaded rod 211 drives the two second limiting bodies 213 to move in coordination. At the same time, the two second limiting bodies 213 are threadedly matched with the side surfaces of the second threaded rod 211. The rotation directions are different, so the third motor 212 drives the two second limiting bodies 213 to move symmetrically to a position convenient for clamping the contact plate, and then extends the two second electric telescopic rods 214 at the same time. The two second electric telescopic rods 214 drive the flexible ring 220 on the side of the second fixed body 215 to contact the side of the contact plate, and at the same time start the air pump 218. The air pump 218 reduces the pressure in the area between the partition 217 and the contact plate, thereby firmly fixing the contact plate, and then the second motor 26 drives the rotating rod 210 to rotate, thereby rotating the contact plate to an angle that fits with the mounting groove of the support shell, thereby improving the efficiency and accuracy of clamping and improving the fit of subsequent grinding.

[0044] Then, the two fourth motors 31 are started, and the two fourth motors 31 drive the third threaded rods 33 to rotate, and the third threaded rods 33 cooperate to drive the two third limit bodies 35 to move to a position close to the installation slot, and then the fifth motor 36 is started, and the fifth motor 36 drives the fixed rod 39 to rotate, and several fourth electric telescopic rods 311 on the side of the fixed rod 39 drive the grinding plate 312 to contact with the supporting shell, and grind along the installation slot. During grinding, the pressure sensor 313 can control the side of the grinding plate 312 to fit with the supporting shell for grinding, and at the same time, the controller can The moving trajectory of the rod 39 is recorded to obtain the accurate trajectory of the installation groove. After the grinding is completed, the fourth motor 31 drives the fixed rod 39 to move to a position close to the contact plate, and the fifth motor 36 drives the fixed rod 39 to grind the side of the contact plate. During grinding, several pressure sensors 313 can ensure that the side of the grinding plate 312 fits with the side of the contact plate, and ensure that the fixed rod 39 grinds the side of the contact plate according to the trajectory of the installation groove, and ensure that the side of the contact plate after grinding can be completely fitted with the installation groove of the support shell, thereby improving the connection strength of subsequent welding.

[0045] When the side of the contact plate and the mounting groove of the support shell are polished, the two third electric telescopic rods 34 drive the fixing rod 39 to rise, and then the first motor 21 is started. Since the rotation directions of the side of the first threaded rod 23 are different, the first limit body 24 and the second limit block 51 can be driven to move inward at the same time, driving the side of the contact plate to contact and fit together with the mounting groove of the support shell. Then, the fourth motor 31 drives the first limit block 41 to move to the welding surface, and the two sixth electric telescopic rods 43 drive the welding gun 47 to move to a position close to the weld. At the same time, the sixth motor 46 drives the welding gun 47 to rotate to align with the weld, and the contact plate and the support shell are welded with high efficiency. By moving according to the trajectory of the fitting surface, the quality of welding by the welding gun 47 can be guaranteed.
