[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Reference Figure 1-Figure 2 The utility model provides an embodiment: a standard subway driver's cab skeleton tooling, including a processing table 1, a stabilizing plate 2 is fixedly connected to the front side of the inner wall of the processing table 1, a middle block 3 is fixedly connected to the middle of the stabilizing plate 2, a first motor 4 is fixedly connected to the inner wall of the middle block 3, and a driving gear 5 is fixedly connected to the output end of the first motor 4. Slide blocks 6 are slidably connected to both sides of the inner wall of the stabilizing plate 2, and tooth plates 7 are fixedly connected to the adjacent diagonal sides of the two slide blocks 6. An extension block 10 is fixedly connected to the top of the slide block 6, and a contact plate 8 is fixedly connected to the inner wall of the extension block 10. Limiting grooves 9 are provided on both sides of the left and right sides of the middle block 3, a matching plate 13 is fixedly connected to the top of the processing table 1, a positioning frame 11 is fixedly connected to the top front side of the matching plate 13, and an adjustment component is arranged on the top of the matching plate 13.
[0030] The corresponding welded left and right components are placed according to the shape of one side of the matching plate 13. In order to ensure that the welding position between the components is always stable, the first motor 4 can be turned on to output power to drive the driving gear 5 to rotate, and then the driving gear 5 is contact-transmitted with the sliders 6 meshed on both sides, and then the sliders 6 on both sides are driven to approach in a similar direction under the limit of the middle block 3 until the contact plates 8 on both sides are in contact with the left and right components respectively, thereby completing the position locking.
[0031] The plurality of tooth plates 7 are meshedly connected with the driving gear 5 . Through such a design, power transmission can be achieved, so that the sliders 6 on both sides are pulled to move synchronously and repel each other, and the driving gear 5 is rotatably connected to the inner wall of the middle block 3 .
[0032] The tooth plate 7 is slidably connected to the inner wall of the limit groove 9. Through the setting of the limit grooves 9 on both sides, the tooth plate 7 can be stably and continuously meshed with the driving gear 5. The slider 6 is slidably connected to the left and right sides of the middle block 3, and the displacement of the sliders 6 on both sides is limited to a minimum range.
[0033] The outer wall of the contact plate 8 is covered with foam, which effectively reduces the friction on the outer surface of the installation component and improves the product quality.
[0034] Reference Figure 3 The adjustment component includes a stabilizing column 12, which is fixedly connected to the top of the matching plate 13. A second motor 14 is fixedly connected to the rear side of the inner wall of the processing table 1, and a screw rod 15 is fixedly connected to the output end of the second motor 14. The outer wall of the screw rod 15 is threadedly connected to a glass supporting platform 19, and the top of the outer wall of the screw rod 15 is threadedly connected to a first bevel gear 16. Second bevel gears 17 are rotatably connected to both sides of the top of the inner wall of the stabilizing column 12, and a pulley 18 is fixedly connected to the front side of the outer wall of the second bevel gear 17.
[0035] When welding is completed and the glass is ready to be installed, the glass can be installed on the glass bearing platform 19 first, and then corresponding to the different installation heights of the driver's cab frame glass, the second motor 14 is started to output power to drive the glass bearing platform 19 to achieve up and down lifting under the limit of the stabilizing column 12. The first bevel gear 16 and the second bevel gear 17 are meshingly connected, and during the single-sided lifting process, the meshing connection between the first bevel gear 16 and the second bevel gear 17 is used, and multiple pulleys 18 are connected by belts. The belt power transmission between the pulleys 18 allows the screw rod 15 on the other side to rotate, and then the threaded anticipation of the limit of the stabilizing column 12 is used to achieve the effect of synchronous and stable lifting of the left and right sides, thereby reducing the pressure on the staff and achieving a quick installation effect.
[0036] The glass support platform 19 is slidably connected to the outer wall of the stabilizing column 12 . The groove-shaped setting on one side of the stabilizing column 12 allows the glass support platform 19 to maintain its position during the threaded connection and to achieve a lifting effect along the thread of the screw rod 15 .
[0037] Working principle:
[0038] When the staff is installing and welding the local subway cab frame tooling, first, ensure that the welded left and right parts are correctly placed according to the shape of one side of the matching plate 13. In order to maintain the stability of the welding position between the parts, the first motor 4 can be started, and the driving gear 5 can be driven to rotate by the power output. The driving gear 5 is engaged with the sliders 6 on both sides, so that the sliders 6 move toward each other under the limit of the middle block 3 until the contact plate 8 is in close contact with the left and right parts, thereby ensuring the position is fixed.
[0039] After welding is completed, when preparing to install the glass, first place the glass on the glass bearing platform 19. According to the requirements of the installation height of the cab frame glass, start the second motor 14 so that its output power drives the glass bearing platform 19 to move up and down under the limit of the stabilizing column 12. In this process, the screw rod 15 on the other side rotates through the meshing of the first bevel gear 16 and the second bevel gear 17, and the belt transmission between the pulleys 18. Under the limit of the thread and the stabilizing column 12, the left and right sides achieve a synchronous and stable lifting effect, thereby reducing the operating pressure of the staff and improving the installation efficiency.
[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
