Compare current barb clamping device, the device has overcome the problem that the slope phenomenon appears in auto parts, presss from both sides tight piece and the dogtooth that presss from both sides tight dish moreover and applies paint the surface that can protect auto parts after the rust inhibitor with a brush.

Description

A kind of auto parts hang welding fixture device

Technical field

The utility model relates to auto parts production unit field, is specifically related to a kind of auto parts and hangs welding fixture device.

Background technology

At present, the part of the middle with holes such as automobile hanging retaining plate, when assemble welding, all needs to use special barb gripping unit to position. The barb pin quantity of existing auto parts barb clamping positioning mechanism is two, and two barb pins become the angle of 180 ° to arrange, and when clamp operation, tilt phenomenon easily occurs in part, can not ensure that part can clamp and put in place, thus can affect welding operation.

Practical novel content

The purpose of this utility model is to provide a kind of auto parts to hang welding fixture device, ensures that auto parts there will not be tilt phenomenon when weld clamp.

For achieving the above object, base case of the present utility model is: a kind of auto parts hang welding fixture device, comprise the hanger bar, the upper disk surface that are fixedly connected with welding machine frame and it is positioned at two, hanger bar both sides barb and clamp mechanism, barb clamps mechanism and comprises support bar, motion bar and extension spring, the upper end of support bar is welded with hanger bar, the movable upper end of the lower end of support bar and motion bar is hinged, extension spring is fixedly installed between support bar and motion bar, and the lower end of motion bar is L-shaped.

Principle of work and the advantage of this scheme are: two barb apparatus river auto parts being arranged at hanger bar both sides catch on, extension spring provides tensile-elasticity to reach balance with the gravity with auto parts, the L-shaped motion bar of lower end contact with auto parts and by auto parts pillar stiffener. In the vertical direction, the clamping dish being welded on the lower end of hanger bar is supplied to auto parts reverse clamping force, interact by clamping dish and two motion bars like this, vertical direction and horizontal direction limit the displacement of auto parts, in whole process, barb clamps mechanism and provides the anchorage force of auto parts and the frictional force between clamping dish and auto parts, and such auto parts just when being clamped by this device, there will not be tilt phenomenon. Comparing existing barb gripping unit, this device overcomes the problem that tilt phenomenon occur in auto parts.

Prioritization scheme one: based on the preferred version of scheme, the lower card of clamping dish is provided with convex tooth.Convex tooth makes clamping dish more be conducive to clamping auto parts, prevents auto parts to tilt further.

Preferred version two: the preferably preferred version of, the angle that the lower end of motion bar is fixedly installed between motion bar is the clamping block of 90 °, and clamping block is connected with motion bar bolt. Employ clamping block can portable propelling bar processing, the most important thing is to regulate very easily the levelness one of two barbs clampings mechanisms to prevent auto parts from tilting when clamped. Because the levelness of auto parts when being clamped by this device just can be adjusted by the position between adjustment clamping block and motion bar. This operation also facilitating this device uses.

Preferred version three: the preferably preferred version of two, the outside surface of convex tooth and clamping block is also coated with and is brushed with rust-preventive agent. The clamping block having brushed rust-preventive agent is all the parts directly contacted with auto parts with clamping dish, so can protect the surface of auto parts after the convex tooth brushing rust-preventive agent of clamping block and clamping dish.

Prioritization scheme four: as the further optimization to prioritization scheme three, circular arc shape is arranged in the upper end of clamping block. The clamping block that circular arc shape is arranged in upper end can reduce contact area when clamping force is constant, is conducive to the welding operation of auto parts.

Accompanying drawing explanation

Fig. 1 is the structural representation that a kind of auto parts of the utility model hang welding fixture device embodiment.

Embodiment

Below by embodiment, the utility model is described in further detail:

Reference numeral in Figure of description comprises: hanger bar 1, clamping dish 2, support bar 3, extension spring 4, motion bar 5, clamping block 6, convex tooth 21.

Embodiment is substantially as shown in Figure 1: a kind of auto parts hang welding fixture device, comprises the hanger bar 1 being fixedly connected with original welding machine frame and two barbs clampings mechanisms, and two barbs clampings mechanisms are symmetricly set in the both sides of hanger bar 1. Barb clamps mechanism and comprises support bar 3, motion bar 5, extension spring 4 and clamping block 6, the upper end of support bar 3 is welded with hanger bar 1, the lower end of support bar 3 and the movable upper end of motion bar 5 are hinged, and extension spring 4 is fixedly installed between support bar 3 and motion bar 5. In the present embodiment, its motion bar 5 times ends supporting clamping effect of auto parts being fixedly installed clamping block 6, clamping block 6 is mounted by means of bolts on the lower end of motion bar 5, and the angle between clamping block 6 and motion bar 5 is set to 90 °. Like this, auto parts just can be caught on by the barb apparatus being arranged at hanger bar 1 both sides, but, even if auto parts are caught on, still there will be tilt phenomenon. So, in the present embodiment, the bottom of hanger bar 1 is provided with clamping dish 2, and the upper disk surface of clamping dish 2 welds with hanger bar 1, lower card is also provided with convex tooth 21. Jointly coordinate by clamping dish 2 and clamping block 6 and auto parts are caught on and it is suspended on aerial to complete the welding of auto parts.

Certainly, motion bar 5 is L-shaped in the present embodiment, do not use clamping block 6 still can reach the effect that auto parts are clamped aloft, but employ clamping block 6 can portable propelling bar 5 processing, the most important thing is to regulate very easily the levelness one of two barbs clampings mechanisms to prevent auto parts from tilting when clamped. As shown in Figure 1, circular arc shape is also arranged in the upper end of clamping block 6, clamps like this and will become linear contact lay by face contact when block 6 contacts with auto parts, reduces contact area when clamping force is constant, be conducive to the welding operation of auto parts.In order to protect auto parts injury-free, the convex tooth 21 of clamping dish 2 and the outside surface of clamping block 6 are also coated with and are brushed with rust-preventive agent.

Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this. Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, it is also possible to make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability that the utility model is implemented. The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification sheets etc. record the content that may be used for explaining claim.
