Detailed Description

The present invention will be further described with reference to the accompanying drawings. Embodiments of the present invention include, but are not limited to, the following examples.

Example 1:

the embodiment aims to solve the technical problems that the existing clamping process pointed out in the background art is mostly carried out manually, the automation degree is low, the clamping speed is low, and the machining efficiency is reduced.

referring to fig. 1-3, a welding clamping device, including base 1, holding strip 5, still include telescopic link 2, base 1 for have be used for fixing a position the work piece the reference surface and can fix on corresponding platform can, holding strip 5 its shape does not do the restriction, have be used for compressing tightly the reference surface of work piece can, should fix a position the work piece and compress tightly the reference surface of work piece and can be the inclined plane, plane or perpendicular, carry out corresponding design according to the work piece setpoint, telescopic link 2 goes up and down and is used for driving holding strip 5 to be close to base 1 and carries out the work piece centre gripping, telescopic link 2 is one of hydraulic stem, pneumatic rod, electric telescopic link, screw rod elevating system, these are all the prior art that frock clamp field technical personnel are familiar, the description is omitted herein. The moving mode of holding strip 5 can be directly by 2 vertical drive lifts of telescopic link and carry out the centre gripping, also can be for 2 pulling holding strips 5 of telescopic link carry out the pivoted mode and carry out the centre gripping.

The clamping strip 5 rotates for clamping and has two designs:

The first method comprises the following steps: referring to fig. 1, set up the articulated seat of upset 3 and be used for the upset of holding strip 5 between base 1 and holding strip 5, the center of rotation of the articulated seat of upset 3 is for articulating the department with base 1, and telescopic link 2 is articulated with holding strip 5, goes up and down through telescopic link 2 and stimulates holding strip 5 and rotates around the articulated department of the articulated seat of upset 3 with base 1.

second (not shown): holding strip 5 directly articulates on base 1, and telescopic link 2 also articulates and does on base 1 simultaneously, rotates around its articulated department with base 1 when telescopic link 2 goes up and down to the movement track of its pitch arc when cooperation holding strip 5 rotates, realizes that 2 lifts and pulls holding strip 5 of telescopic link with this and rotates the purpose that carries out the clamping to the work piece.

The articulated seat of upset has been lacked for first mode to the second mode, nevertheless need correspond for first mode base 1 and set up articulated mounted position, and base 1 structure is more complicated, has the articulated seat of upset simultaneously and can promote base 1 and holding strip 5 distance each other a little, is convenient for carry out corresponding clamp splice 6 and lower clamp splice 7 installation to embodiment 3 and arranges.

And meanwhile, at least one leaning seat 4 is arranged on the base 1, a groove which is matched with the rotating surface of the holding strip 5 in the same plane and the shape of the holding strip 5 is formed in the leaning seat 4, and the holding strip 5 is embedded into the groove of the leaning seat 4 when rotating and falling down, so that the accuracy of the clamping position of the holding strip 5 is ensured.

The working process is as follows: the workpiece is placed on the base 1, the telescopic rod 2 drives the clamping strips 5 to lift or rotate, the clamping strips 5 are close to and compress the workpiece, meanwhile, the clamping strips 5 partially fall into the grooves of the leaning seats 4, and the process of automatically clamping the workpiece in a single point mode is completed.

Example 2:

The embodiment aims to solve the technical problems that manual clamping pointed out in the background art causes workpiece position deviation, clamping position is not accurate, welding position accuracy cannot be guaranteed, and qualified rate of welded products is low.

Referring to fig. 4, the other parts of this embodiment are the same as embodiment 1, and the difference from embodiment 1 is that: install locating lever 8 on base 1, locating lever 8 can pass the preset hole that is used for the location on the plate-shaped workpiece, so can realize the quick accurate fixed to work piece clamping position.

Example 3:

The embodiment aims to solve the technical problem that if the sizes of parts such as a floor, an engine compartment side beam cover plate, an engine compartment side plate and the like are changed, corresponding tool fixtures need to be redesigned.

Other parts of the present embodiment are the same as those of the other embodiments, and the present embodiment is different from the other embodiments in that: an upper clamping block 6 is detachably arranged on the clamping strip 5, and a lower clamping block 7 corresponding to the upper clamping block 6 is arranged on the base 1. The opposite surfaces of the upper clamping block 6 and the lower clamping block 7 are horizontal surfaces, inclined surfaces, curved surfaces or vertical surfaces, referring to fig. 1, the opposite surfaces of the pair of upper clamping block 6 and the lower clamping block 7 are horizontal surfaces, and the opposite surfaces of the other pair of upper clamping block 6 and the lower clamping block 7 are approximately vertical inclined surfaces, so that a punched special-shaped workpiece with inclined surfaces and horizontal surfaces can be clamped and positioned. Referring to fig. 4 again, the opposite surfaces of the two pairs of upper clamping blocks 6 and the lower clamping blocks 7 are horizontal surfaces, so that the horizontal position of the workpiece is better clamped. Referring to fig. 5 again, one surface of the pair of upper clamping blocks 6 opposite to the lower clamping blocks 7 is a horizontal surface, and the other surface of the pair of upper clamping blocks 6 opposite to the lower clamping blocks 7 is an inclined surface, so that the punched special-shaped workpiece with the inclined surface and the horizontal surface can be clamped and positioned. Although not shown in the drawings, the surface of the upper clamp block 6 facing the lower clamp block 7 is a vertical surface, the surface of the upper clamp block 6 facing the lower clamp block 7 may be a vertical surface, and the vertical surface portion of the workpiece may be clamped.

therefore, workpieces in different shapes can be automatically clamped by only replacing the smaller upper clamping block 6 and the smaller lower clamping block 7 without changing the base 1 and the clamping strip 5, the situation that the clamp needs to be redesigned after the clamped workpieces are changed is avoided, meanwhile, the clamping reference surface of the clamp can be simplified by the upper clamping block 6 and the lower clamping block 7, and the area of the machined reference surface is reduced.

Example 4:

The embodiment aims to solve the technical problems that the tool clamp pointed out in the background technology only clamps the welded part, the welded part cannot be positioned, the process time for manually adjusting the welded part is long, the accuracy is low, and the welding quality and the welding speed are caused to be double-low.

Referring to fig. 6 to 8, the other parts of the present embodiment are the same as the other embodiments, and the differences from the other embodiments are as follows: a welding part fixing seat 10 is arranged on the base 1, and a welding guide seat 9 is arranged on the holding strip 5.

The welding part fixing seat 10 has a function of fixing the welding part to be welded, such as locking by screws, compressing by springs, etc., and the welding guide seat 9 is used for guiding the welding head of the welding tool to approach the welding position, and generally, a circular hole is provided in the welding guide seat 9, so as to guide or directly mount the welding tool thereon. The welding quality and the welding yield are improved by fixing the welded piece and guiding the welding device.
