Description

Technical Field

[0001] The utility model relates to the technical field of assembly jigs, and specifically relates to a servo vehicle frame assembly jig. Background Art

[0002] In the rapid development of the automobile manufacturing industry, the precise assembly of the vehicle frame assembly is a key link to ensure the performance and quality of the whole vehicle. As the skeleton of the vehicle, the precise docking and fixing of its various components are crucial for the stability, safety and driving experience of the whole vehicle. However, in the existing vehicle frame assembly process, the widely used fixture design often relies on a single pulley system to drive the movement of the longitudinal beam, and this traditional method has exposed some significant technical bottlenecks in practical applications.

[0003] The traditional fixture adopts the way that the pulley is in direct contact with the longitudinal beam, as Figure 5 shown, and drives the longitudinal beam to move along the predetermined track by the rolling of the pulley. However, there is a fundamental problem with this design: the friction between the pulley and the longitudinal beam completely depends on the weight of the longitudinal beam itself and the resistance generated during the movement. In actual operation, due to the influence of various factors such as the material of the longitudinal beam, the surface state, and the load change, this dependent friction is often difficult to maintain stability, resulting in the following problems:

[0004] Insufficient friction: In the case where the longitudinal beam is light in weight, the friction between the pulley and the longitudinal beam may not be sufficient to overcome the movement resistance, thus causing a slipping phenomenon. Slipping will not only cause uneven movement speed of the longitudinal beam, but also result in deviation of the movement position, affecting the assembly accuracy.

[0005] Limited positioning accuracy: Due to the existence of the slipping problem, it is difficult for the traditional fixture to meet the high-precision requirements when positioning the longitudinal beam. Even if the initial position is set accurately, the cumulative error caused by slipping during the movement will gradually increase, ultimately affecting the overall quality of the vehicle frame assembly.

[0006] Therefore, a servo vehicle frame assembly jig is needed to overcome the occurrence of the above problems. Summary of the Utility Model

[0007] In order to solve the above problems, the embodiment of the utility model provides a servo vehicle frame assembly jig, achieving the purpose of solving the problems proposed in the background art.

[0008] The embodiment of the utility model specifically adopts the following technical solutions to achieve the above purpose: a servo vehicle frame assembly jig, including a base, and a clamping assembly for clamping the longitudinal beam is arranged on the base;

[0009] The clamping assembly includes a housing arranged on the base, a first pulley rotatably connected inside the housing for clamping inside the longitudinal beam, a second pulley arranged inside the housing for clamping inside the longitudinal beam, a transmission assembly arranged inside the housing for drivingly connecting the first pulley and the second pulley, a motor arranged inside the housing for driving the first pulley to rotate, and an electric push rod arranged inside the housing for driving the second pulley to move up and down; when the motor drives the first pulley to rotate, the second pulley is driven to rotate through the transmission assembly.

[0010] The transmission assembly includes a first gear fixedly connected to the first pulley, a first connecting plate rotatably arranged on the first gear, a second gear rotatably arranged on the first connecting plate and meshing with the first gear, a second sprocket fixedly connected to the second gear, a second connecting plate rotatably arranged on the second gear, a first sprocket rotatably arranged on the second connecting plate, and a chain arranged on the first sprocket and the second sprocket; the first sprocket is fixedly connected to the second pulley.

[0011] The first pulley is located directly above the second pulley.

[0012] A chute is formed on the housing, and the second pulley is slidably arranged inside the chute.

[0013] A baffle for covering the chute is rotatably connected to the second pulley.

[0014] The beneficial effects of the embodiments of the present utility model are as follows:

[0015] During actual use, after placing the longitudinal beam on the first pulley, the electric push rod pushes the second pulley to move, so as to clamp the longitudinal beam through the first pulley and the second pulley. Subsequently, the motor drives the first pulley to rotate, and then the second pulley is synchronously driven to rotate through the transmission assembly, so that the longitudinal beam can be driven to move by the rotation of the first pulley and the second pulley; in this application, the pressure between the pulley and the longitudinal beam not only depends on the self-weight of the longitudinal beam, but also the pressure provided by the electric push rod, thereby increasing the friction between the pulley and the longitudinal beam, avoiding slipping due to insufficient friction, facilitating driving the longitudinal beam to move, and facilitating accurate positioning of the longitudinal beam.

[0024] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0025] See Figures 1 to 4 , the embodiment of the present invention discloses a servo vehicle frame assembly assembly fixture, including a base 1, and a clamping assembly 2 for clamping the longitudinal beam is arranged on the base 1; the base 1 is arranged on an electric guide rail, so as to drive the device to move through the electric guide rail;

[0026] The clamping assembly 2 includes a housing 21 arranged on the base 1, a pulley one 22 rotatably connected inside the housing 21 for clamping inside the longitudinal beam, a pulley two 23 arranged inside the housing 21 for clamping inside the longitudinal beam, a transmission assembly 24 arranged inside the housing 21 for drivingly connecting the pulley one 22 and the pulley two 23, a motor 25 arranged inside the housing 21 for driving the pulley one 22 to rotate, and an electric push rod 26 arranged inside the housing 21 for driving the pulley two 23 to move up and down; when the motor 25 drives the pulley one 22 to rotate, the pulley two 23 is driven to rotate through the transmission assembly 24;

[0027] In actual use, after placing the longitudinal beam on the pulley one 22, the electric push rod 26 pushes the pulley two 23 to move, so as to clamp the longitudinal beam through the pulley one 22 and the pulley two 23, and then the motor 25 drives the pulley one 22 to rotate, so as to synchronously drive the pulley two 23 to rotate through the transmission assembly 24, and the longitudinal beam can be driven to move through the rotation of the pulley one 22 and the pulley two 23; in this application, the pressure between the pulley and the longitudinal beam not only depends on the self-weight of the longitudinal beam, but also the pressure provided by the electric push rod 26, so as to increase the friction between the pulley and the longitudinal beam, avoid slipping due to insufficient friction, facilitate driving the longitudinal beam to move, and facilitate the precise positioning of the longitudinal beam.

[0028] As a further description of this application:

[0029] The transmission assembly 24 includes a first gear 241 fixedly connected to the first pulley 22, a first connecting plate 242 rotatably arranged on the first gear 241, a second gear 243 rotatably arranged on the first connecting plate 242 and meshing with the first gear 241, a second sprocket 244 fixedly connected to the second gear 243, a second connecting plate 245 rotatably arranged on the second gear 243, a first sprocket 246 rotatably arranged on the second connecting plate 245, and a chain 247 arranged on the first sprocket 246 and the second sprocket 244; the first sprocket 246 is fixedly connected to the second pulley 23;

[0030] When the motor 25 drives the first pulley 22 to move, the first gear 241 drives the second gear 243 to rotate, so as to drive the first sprocket 246 to rotate through the second sprocket 244, and the purpose of driving the second pulley 23 to rotate can be achieved;

[0031] When the second pulley 23 moves, the first connecting plate 242 and the second connecting plate 245 rotate, causing the included angle between the first connecting plate 242 and the second connecting plate 245 to change. The first gear 241 and the second gear 243 always maintain a meshing relationship, so as to ensure that when the second pulley 23 moves, the first pulley 22 can still drive the second pulley 23 to rotate through the transmission assembly 24;

[0032] By setting the transmission assembly 24, a single motor 25 can be used to drive the first pulley 22 and the second pulley 23 to rotate, reducing the setting of the motor 25 and facilitating ensuring that the rotational speeds of the first pulley 22 and the second pulley 23 are consistent.

[0033] As a further description of the present application:

[0034] The first pulley 22 is located directly above the second pulley 23. When the longitudinal beam is placed on the first pulley 22, since the first pulley 22 is above, the longitudinal beam is supported by the first pulley 22 at this time. At this time, when the second pulley 23 moves downward, it is squeezed along the gravity direction of the longitudinal beam, so that the movement of the second pulley 23 does not need to resist the gravity of the longitudinal beam, which is convenient for the electric push rod 26 to drive the second pulley 23 to move.

[0035] As a further description of the present application:

[0036] A chute 3 is formed on the housing 21, and the second pulley 23 is slidably arranged inside the chute 3. A baffle 4 for covering the chute 3 is rotatably connected to the second pulley 23; by setting the baffle 4, when the second pulley 23 moves to any position, the baffle 4 can block the chute 3, thereby preventing foreign matters from invading the inside of the housing 21 through the chute 3.

[0037] As a description of the use of the present application:

[0038] Such as Figure 1As shown, the longitudinal beam is positioned and conveyed to the workbench by this device, and the longitudinal beam is positioned by the clamping components at various places in the conveying table, so as to fit and position the welding positions of each part of the vehicle frame, thus facilitating the later welding assistance for the vehicle frame.
