Description

Technical Field

[0001] The utility model relates to the technical field of automobile fixtures, and more specifically to a tooling fixture for processing automobile shells. Background Art

[0002] The automobile body shell needs to be fixed with a clamp during processing to ensure the stability of the shell during processing.

[0003] The existing clamp can only fix the body shell in one position. When the outer processing of the shell is completed and the inner processing needs to be carried out, manpower is required to flip the shell, which is troublesome, time-consuming and labor-intensive. The existing patent is a tooling fixture for fixing the automobile body shell. The patent authorization number is CN214518841U. The motor drives the screw rod to rotate, so that the slider connected to the screw rod thread moves to the right, the slider drives a placement plate to move to the right, and drives another placement plate to move to the right through the connecting plate. The two placement plates drive the body shell to move to the right, and the body shell is extended. At this time, the inside of the body shell can be processed from the bottom of the body shell.

[0004] However, in patent authorization number CN214518841U, when it is necessary to process the inside of the car body shell, the motor drives the screw to rotate, so that the slider connected to the screw thread moves to the right, the slider drives a placement plate to move to the right, and the connecting plate drives another placement plate to move to the right. The two placement plates drive the car body shell to move to the right, and the car body shell is extended. Since the movement of the placement plate will form a cantilever structure with the support platform, and the placement plate has no support, it is easy to cause the placement plate to bend, which will cause danger to the personnel working on the inside of the car body shell. Therefore, we propose a tooling fixture for processing automobile shells to solve the above-mentioned problems. Utility Model Content

[0030] Example

[0031] See also Figure 1-4A tooling fixture for processing an automobile shell comprises a placing frame 1, a mounting frame 2 symmetrically fixedly connected to the top of the placing frame 1, and a clamping cylinder 3 symmetrically installed at the mounting frame 2. A supporting platform 4 is installed below the placing frame 1, and an extended supporting frame 5 with a frame-shaped structure is welded to the end of the supporting platform 4. A slide rail 6 extending to the end of the extended supporting frame 5 is symmetrically installed on the edge of the upper surface of the supporting platform 4;

[0032] The lower surface of the placement rack 1 is symmetrically fixedly connected with a slide block 7 which is slidably connected with the slide rail 6;

[0033] The outer side walls of the support platform 4 and the extension support frame 5 are rotatably connected with a driven gear 8 and a driving gear 9, respectively. A transmission steel belt 10 is transmission-connected between the driving gear 9 and the driven gear 8, and the transmission steel belt 10 is transmission-connected with the placement frame 1. The inner side wall of the extension support frame 5 is installed with a servo motor 11 whose power output end is transmission-connected with the driving gear 9;

[0034] A square steel 14 is welded to the bottom of the welding point between the support platform 4 and the extended support frame 5;

[0035] It should be noted that when the fixture for processing the automobile shell is used, the automobile shell is placed on the placement frame 1 and located between the mounting frames 2 and is clamped and fixed by the clamping cylinder 3;

[0036] When the inside of the vehicle body shell needs to be processed, an external control device is connected to the servo motor 11, and the control device is used to control the forward and reverse rotation of the power output end of the servo motor 11. The power output end of the servo motor 11 drives the active gear 9 to rotate clockwise, and cooperates with the driven gear 8 to make the transmission steel belt 10 operate, so that the slider 7 cooperates with the slide rail 6 to slide, and the placement rack 1 moves toward the extended support rack 5. The structural strength of the welding point between the support platform 4 and the extended support rack 5 is strengthened by using square steel 14, so that the placement rack 1 is always supported by the structure after changing its orientation, thereby ensuring the safety of workers when working on the inside of the vehicle body shell.

[0037] like Figure 1 As shown, the bottom edge of the support platform 4 and the extension support frame 5 away from the square steel 14 is symmetrically installed with a lifting hydraulic cylinder 15;

[0038] It should be noted that, by utilizing the external hydraulic control device of the jacking hydraulic cylinder 15 to control the extension and retraction of the movable end of the jacking hydraulic cylinder 15, the jacking hydraulic cylinder 15 is utilized to jack up the support platform 4 and the extension support frame 5 to a certain height, thereby facilitating the workers to enter the inner side of the extension support frame 5 to perform operations on the inner side of the vehicle shell.

[0039] like Figure 1 As shown, a rib plate having an isosceles trapezoidal structure is fixedly connected to the joint of the mounting frame 2 and the placing frame 1 and to one side away from the movable end of the clamping cylinder 3;

[0040] It should be noted that the structural strength of the joint between the mounting frame 2 and the placement frame 1 is improved by using the ribs, thereby preventing the mounting frame 2 from bending and deforming when the clamping cylinder 3 is working.

[0041] like Figure 1 , Figure 2 As shown, a slide groove is provided on the top of the slide rail 6, and the slide groove and the slider 7 are clearance-matched;

[0042] It should be noted that the stability of the slider 7 and the slide rail 6 during the sliding process is ensured, thereby ensuring the stability of the placement rack 1 during the translation process.

[0043] like Figure 1 As shown, a connecting ear 13 is installed on the top of the transmission steel belt 10, and a mounting hole is provided on the surface of the connecting ear 13. A connecting rod 12 plugged and connected to the mounting hole is fixedly connected to the side wall of the placement rack 1 close to the connecting ear 13;

[0044] It should be noted that the placement rack 1 can be driven to move synchronously by the operation of the transmission steel belt 10 and the combination of the connection ear 13 and the connection rod 12 .

[0045] like Figure 4 As shown, the middle section of the square steel 14 corresponds to the welding section of the support platform 4 and the extended support frame 5;

[0046] It should be noted that the square steel 14 can be evenly stressed, thereby enhancing the structural strength of the welding point between the support platform 4 and the extended support frame 5 .

[0047] When in use: place the car shell on the placement rack 1 and between the mounting racks 2 and clamp and fix it using the clamping cylinder 3;

[0048] When the interior of the vehicle body shell needs to be processed, an external control device is connected to the servo motor 11, and the control device is used to control the forward and reverse rotation of the power output end of the servo motor 11. The power output end of the servo motor 11 drives the active gear 9 to rotate clockwise, and cooperates with the driven gear 8 to make the transmission steel belt 10 operate, so that the slider 7 cooperates with the slide rail 6 to slide, and the placement rack 1 moves toward the extended support rack 5. The structural strength of the welding point between the support platform 4 and the extended support rack 5 is strengthened by using square steel 14, so that the placement rack 1 is always supported by the structure after changing its orientation.

[0049] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
