Description

Technical Field

[0001] The utility model relates to an adjustable jig for welding a rack or a support frame. Background Art

[0002] In the manufacturing industry, welding, as a commonly used connection method, has the characteristics of high joint strength, high production efficiency, and excellent corrosion resistance. During the welding process, in order to facilitate the welding work of the parts to be processed, it is necessary to first limit the parts to be processed through a fixture. However, the existing fixtures generally have poor versatility and cannot adapt to workpieces of different sizes for clamping. Generally, workpieces of different sizes need to be adapted to different fixtures. At the same time, the fixed sizes of the existing fixtures are relatively single, and can only correspond to a unique size or be fixed in the horizontal direction, resulting in limited use and poor flexibility. Summary of the Utility Model

[0003] The utility model improves the above problems, that is, the technical problem to be solved by the utility model is to provide an adjustable jig for welding a rack or a support frame, which has a simple structure and is convenient to use.

[0004] The utility model is composed of a welding platform and a fixed baffle arranged on the surface of the welding platform. A clamping mechanism is arranged beside the fixed baffle. The fixed baffle and the clamping mechanism are both detachably connected to the welding platform. The clamping mechanism includes a longitudinal clamping mechanism and a transverse clamping mechanism. There is a transverse clamping space for limiting the workpiece between the transverse clamping mechanism and the fixed baffle. The longitudinal clamping mechanism is used to press above the transverse clamping space to form a longitudinal clamping space.

[0005] Further, the longitudinal clamping mechanism includes a vertical plate, a bottom plate arranged at the lower part of the vertical plate, and an upper mounting plate arranged at the upper part of the vertical plate. A lower mounting plate is arranged on the bottom plate. The transverse clamping mechanism is mounted on the bottom plate. A longitudinal screw rod is arranged on the surface of the vertical plate close to the fixed baffle. Slide bars are arranged on both sides of the longitudinal screw rod. A lifting seat is arranged on the longitudinal screw rod and the two slide bars. A longitudinal cylinder is arranged on the lifting seat. A pressing block is arranged at the output shaft of the longitudinal cylinder. The pressing block extends outwards above the transverse clamping space.

[0006] Further, a threaded hole for cooperating with the longitudinal screw rod is arranged in the middle of the lifting seat. Light holes for the slide bars to pass through are arranged on both sides of the lifting seat.

[0007] Further, both ends of the slide bar are respectively connected to the upper mounting plate and the lower mounting plate. The lower end of the screw rod is rotationally matched with the lower mounting plate. The upper end of the screw rod penetrates through the upper mounting plate and extends upwards. A hand wheel is arranged at the upper end of the screw rod.

[0008] Further, the transverse clamping mechanism includes a movable baffle plate arranged parallel to the fixed baffle plate. The movable baffle plate is driven by a transverse air cylinder to move closer to or away from the fixed baffle plate so as to adjust the size of the transverse clamping space.

[0009] Further, a plurality of through holes are provided on the welding platform. Screws for passing through the through holes are provided below the fixed baffle plate and the clamping mechanism, and fixing nuts are provided at the lower ends of the screws.

[0010] Further, the fixed baffle plate includes an L-shaped plate and reinforcing ribs provided on the L-shaped plate.

[0011] Further, a longitudinal air cylinder manual valve is provided outside the longitudinal air cylinder.

[0012] Further, a transverse air cylinder manual valve is provided outside the transverse air cylinder.

[0013] Compared with the prior art, the utility model has the following beneficial effects: The device has a simple structure and is convenient to use. During installation, according to the actual welding limit requirements, select a suitable installation position, pass the screw below the fixed baffle plate through the through hole of the welding platform and fasten it with a fixing nut; also pass the screw below the clamping mechanism through the through hole of the welding platform and fasten it with a fixing nut. According to the through holes on the welding platform, the position of the fixture can be adjusted arbitrarily to correspond to workpieces of different sizes, reducing the cost of fixture production; during clamping and limiting, by placing the corresponding workpieces in different transverse clamping spaces respectively, the two workpieces are made to contact; by driving the movable plate close to the fixed baffle plate through the transverse air cylinder, the workpiece is clamped to complete the horizontal direction limit of the workpiece; by rotating the screw, the lifting seat, the longitudinal air cylinder of the lifting seat and the pressing block are first lifted and lowered to an appropriate height to ensure that the top travel of the longitudinal air cylinder can clamp the workpiece, and then the pressing block is driven to lift and lower through the longitudinal air cylinder to press the workpiece in the transverse clamping space, so as to realize the vertical direction limit of the workpiece. After the workpiece is limited, the workpiece can be welded, thus realizing the clamping and limiting of workpieces of different heights and the horizontal pressing of workpieces of different sizes, which can effectively improve the welding precision and welding effect, reduce the production cost and improve the production efficiency.
