Abstract
The utility model discloses a manual spot welding joint error proofing mechanism. The manual spot welding joint error proofing mechanism comprises a clamp support, a welding gun pressure plate, a welding joint position stopper, a sensor triggering plate, a sensor, a spring telescoping mechanism and a back plate, wherein the clamp support is fixed with the back plate; the welding gun pressure plate is positioned above the back plate; the welding joint position stopper is positioned above the welding gun pressure plate; one end of the sensor triggering plate sleeves one end of the spring telescoping mechanism; the other end of the sensor triggering plate is connected with the welding joint position stopper; and the sensor is positioned below the spring telescoping mechanism. By using the manual spot welding joint error proofing mechanism, shortcomings existing in manual spot welding are overcome, and a robot spot welding effect is achieved by low cost.
Description
Technical field
The utility model relates to a kind of error prevention means, particularly relates to a kind of manual weld nugget error prevention means.
Background technology
Spot welding is that weldment is assembled into lap joint, and is pressed between two columnar electrodes, utilizes resistance heat fusing base metals, forms the electric resistance welding method of solder joint.Spot welding is mainly used in plate sheet welding, and manual spot welding is due to it, construction cycle and cheap equipment investment are widely used in automobile industry fast.But there is following defect in manual spot welding: one, number of welds cannot be controlled in process of production.Solder joint parameter in two, one work stations cannot be changed (all solder joints can only use a parameter), cannot be competent at for more complicated welding situation.Three, the position of solder joint is unstable, and owing to being Artificial Control, bond pad locations exists deviation and the low problem of precision.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of manual weld nugget error prevention means, and it solves the defect that manual spot welding exists, and originally obtains the effect of Robot Spot Welding with lower one-tenth.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of manual weld nugget error prevention means, it is characterized in that, it comprises fixture mount, welding gun pressing plate, bond pad locations block, sensor-triggered sheet, sensor, telescopic spring mechanism, backboard, fixture mount and backboard are fixed, welding gun pressing plate is positioned at the top of backboard, bond pad locations block is positioned at the top of welding gun pressing plate, one end of sensor-triggered sheet is enclosed within on the one end with telescopic spring mechanism, the other end of sensor-triggered sheet is connected with bond pad locations block, sensor is positioned at the below of telescopic spring mechanism.
Preferably, the structure of described sensor-triggered sheet is 90 degree bending structures.
Preferably, between described fixture mount and backboard, be to fix by least two the first bolts.
Preferably, the bottom of described fixture mount is provided with the second bolt.
Preferably, the top of described fixture mount is provided with an arc notch.
Preferably, described telescopic spring mechanism comprises spring and slide-bar, and spring housing is on slide-bar.
Preferably, described slide-bar is provided with a slide-bar cover.
Preferably, the top of described slide-bar cover is provided with cover plate.
Positive progressive effect of the present utility model is: the utility model solves the defect that manual spot welding exists, and originally obtains the effect of Robot Spot Welding with lower one-tenth.
Brief description of the drawings
Fig. 1 is the structural representation of the manual weld nugget error prevention means of the utility model.
Fig. 2 is the structural representation of the utility model medi-spring telescoping mechanism.
Detailed description of the invention
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the manual weld nugget error prevention means of the utility model comprises fixture mount 1, welding gun pressing plate 2, bond pad locations block 3, sensor-triggered sheet 4, sensor 5, telescopic spring mechanism 6, backboard 7, fixture mount 1 is fixing with backboard 7, welding gun pressing plate 2 is positioned at the top of backboard 7, bond pad locations block 3 is positioned at the top of welding gun pressing plate 2, one end of sensor-triggered sheet 4 is enclosed within on the one end with telescopic spring mechanism 6, the other end of sensor-triggered sheet 4 is connected with bond pad locations block 3, and sensor 5 is positioned at the below of telescopic spring mechanism 6.The structure of sensor-triggered sheet 4 is 90 degree bending structures.Between fixture mount 1 and backboard 7, be fixing, fixed like this by least two the first bolts 8.The bottom of fixture mount 1 is provided with the second bolt 9, and convenient like this and other elements are fixed.The top of fixture mount 1 is provided with an arc notch 10, facilitates like this movement of welding gun pressing plate 2 and the movement of bond pad locations block 3.As shown in Figure 2, telescopic spring mechanism comprises spring 61 and slide-bar 62, and spring 61 is enclosed within on slide-bar 62, so convenient slip.Slide-bar 62 is provided with a slide-bar cover 63, protects like this.The top of slide-bar cover 63 is provided with cover plate 11, can protect like this slide-bar 62 and slide-bar cover 63.
The position that act as fixing welding gun of bond pad locations block, ensure the accuracy of bond pad locations, in the time that welding gun leans on into whole error prevention means, spring contraction mechanism is pressed into, trigger the sensor of back location, PLC (Programmable Logic Controller, programmable logic controller (PLC)) can be according to the position of trigger sensor, send instruction to welding controller, export correct welding parameter.In the time that sensor is not triggered, the welding gun output of cannot discharging, when whole welding process does not complete, fixture cannot be opened automatically, prevents thus the risk of solder joint solder skip and wrong weldering.
The utility model has solved the existing quality risk of manual spot welding, controls position, parameter and the quantity of each solder joint by the combination of fixture mount and sensor, compared to traditional manual spot welding, has improved reliability and the scope of application thereof of manual spot welding; Compared to Robot Spot Welding, input cost and construction cycle are reduced.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect to solution of the present utility model further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
