Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, and particularly relates to a frame fixture. Background Art

[0002] The frame is a framework structure straddling the front and rear axles of an automobile, commonly known as the crossbeam. It is the base of the automobile and generally consists of two longitudinal beams and several crossbeams. Supported by the suspension device, front axle and rear axle on the wheels, the frame must have sufficient strength and stiffness to withstand the load of the automobile and the impact transmitted from the wheels. The function of the frame is to support and connect each assembly of the automobile, keep each assembly in a relatively correct position, and bear various loads inside and outside the automobile.

[0003] When manufacturing automobiles at present, fixtures are needed to fix the frame for assembly. The positions of the existing fixtures for frame assembly are fixed and cannot adapt to frames of different sizes. Different fixtures are required for manufacturing and assembling different frames, which will increase the production cost and reduce the production efficiency.

[0004] To solve this technical problem, relevant technical personnel designed a frame fixture as shown in CN220945092U. By adding gears to the fixture and racks to the bottom plate, and through the transmission of gears and racks, the fixture is driven by a motor to move, so as to adjust the position between the fixtures. However, since the motor rotates continuously to drive the fixture to move continuously, it is easy to stop too early or too late and difficult to stop at the required position. The accuracy of the fixture position after movement needs to be improved. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the utility model provides a frame fixture to solve the technical problem that in the existing frame fixture applicable to frames of various lengths, it is difficult for the fixture to stop at the required position mentioned in the above background art.

[0006] To solve this technical problem, the technical solution adopted by the utility model is as follows:

[0008] A plurality of the fixed fixtures are provided and fixed on the base, a plurality of the sliding fixtures are provided and slidably connected to the base, and the racks are respectively arranged on both sides of the base;

[0009] The driving mechanism is arranged on the sliding fixture, and the driving mechanism includes a driving component and a driven component which are respectively rotatably arranged on the sliding fixture. The rotation of the driving component can drive the driven component to rotate intermittently, and the rotation of the driven component can make the sliding fixture slide by extruding the rack.

[0010] Further, the driven assembly includes a driven rotating rod, a sprocket wheel, and a gear; the driven rotating rod is rotatably connected to the sliding fixture, the sprocket wheel and the gear are respectively coaxially fixed on the driven rotating rod, the gear meshes with the rack, and the rotation of the driving assembly can intermittently drive the sprocket wheel to rotate.

[0011] Further, the driving assembly includes a motor, a driving rotating rod, a turntable, and a toggle rod; the motor is arranged on the sliding fixture, the driving rotating rod is coaxially fixed on the output shaft of the motor, the turntable is coaxially fixed at one end of the driving rotating rod away from the motor, the toggle rod is eccentrically fixed on the turntable, and can intermittently drive the sprocket wheel to rotate.

[0012] Further, an arc-shaped block is also fixed on the turntable, the arc-shaped block and the toggle rod alternately contact the sprocket wheel, and the arc-shaped block can limit the rotation of the sprocket wheel.

[0013] Further, flexible pads are also provided on the clamping plates of the fixed fixture and the sliding fixture.

[0014] Compared with the prior art, the advantages of the present application are as follows:

[0015] In the present application, the rotation of the driving assembly causes the driven assembly to rotate intermittently, and further causes the sliding fixture to slide intermittently, so that the operator has enough time to stop the sliding of the sliding fixture and avoid the sliding fixture moving outside the required range.

[0024] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0025] Please also read Figure 1 and Figure 2 , this embodiment provides a frame clamp, characterized in that it includes a base 1, a fixed clamp 2, a sliding clamp 3, a driving mechanism 4 and a rack 5;

[0026] A plurality of fixed clamps 2 are provided and fixed on the base 1, a plurality of sliding clamps 3 are provided and slidably connected to the base 1, and racks 5 are respectively provided on both sides of the fixed base 1; specifically, a fixed clamp 2 and a sliding clamp 3 are respectively provided on both sides of the base 1, and the distance between adjacent clamps can be changed by sliding the sliding clamp 3 to adapt to frames of different lengths.

[0027] The driving mechanism 4 is arranged on the sliding clamp 3, and the driving mechanism 4 includes a driving component 41 and a driven component 42 which are rotatably arranged on the sliding clamp 3 respectively. The rotation of the driving component 41 can drive the driven component 42 to rotate intermittently, and the rotation of the driven component 42 can make the sliding clamp 3 slide by squeezing the rack 5.

[0028] In the present application, the rotation of the driving component 41 causes the driven component 42 to rotate intermittently, thereby causing the sliding clamp 3 to slide intermittently, so that the operator has enough time to stop the sliding of the sliding clamp 3 and prevent the sliding clamp 3 from moving out of the desired range.

[0029] In other embodiments, the driven assembly 42 includes a driven rotating rod 421, a groove wheel 422 and a gear 423; the driven rotating rod 421 is rotatably connected to the sliding fixture 3, the groove wheel 422 and the gear 423 are coaxially fixed on the driven rotating rod 421, respectively, the gear 423 is meshed with the rack 5, and the rotation of the driving assembly 41 can intermittently drive the groove wheel 422 to rotate. Since the groove wheel 422 and the gear 423 are coaxially fixed on the driven rotating rod 421, respectively, when the driving assembly 41 drives the groove wheel 422 to rotate, the groove wheel 422 drives the driven rotating rod 421 to rotate, and then drives the gear 423 to rotate. Since the gear 423 is meshed with the rack 5, the rack 5 is fixed, and the gear 423 moves along the rack 5, thereby driving the sliding fixture 3 to slide.

[0030] In other solutions, the driving component 41 includes a motor 411, a driving rotating rod 412, a turntable 413 and a toggling rod 414; the motor 411 is arranged on the sliding fixture 3, the driving rotating rod 412 is coaxially fixed on the output shaft of the motor 411, the turntable 413 is coaxially fixed on one end of the driving rotating rod 412 away from the motor 411, the toggling rod 414 is eccentrically fixed on the turntable 413, and can intermittently drive the grooved pulley 422 to rotate. It should be understood that the motor can hold its output shaft when it stops working.

[0031] In other solutions, an arc-shaped block 415 is also fixed on the turntable. The arc-shaped block 415 and the toggling rod 414 alternately contact the grooved pulley 422, and the arc-shaped block 415 can limit the rotation of the grooved pulley 422. By providing the arc-shaped block 415, it is possible to prevent the grooved pulley 422 from accidentally rotating when the toggling rod 414 moves away.

[0032] In other solutions, flexible pads 6 are also provided on the clamping plates of the fixed fixture 2 and the sliding fixture 3. The flexible pads 6 can reduce the wear on the vehicle frame during clamping. The above vehicle frame fixture can give the operator enough time to stop the fixture at the required position by intermittently moving the fixture.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
