Description
Technical field
This utility model designing mould manufacturing technology field, particularly refers to a kind of fixing point welder lower electrode wear extent detecting device.
Background technology
Bolt/nut welding domestic at present, for ensureing welding quality, prevent solder skip, wrong weldering, simultaneously in order to promote welding efficiency, having begun to realize automatization, with transfer robot, solid point welding machine welds, and job order is: 1. part passes through transfer robot, run above bottom electrode, develop with bottom electrode；2. cylinder drives and presses under upper electrode；3. transformator energising, welding.The running orbit of transfer robot is fixing, but the electrode of solid point welding machine, along with constantly welding has abrasion, make the locus of bottom electrode change.So that there is error in final welding track.
Current wear to electrodes detecting device, total wear extent of the upper and lower electrode of detection, the wear extent giving tacit consent to upper and lower electrode is suitable, then uses the half side-play amount as bottom electrode of total amount.Actually the wear extent of two electrodes is equal is a kind of perfect condition, the loss of upper and lower electrode can not be definitely equal, so the value of detection is inaccurate, the corresponding compensation of robot is not in place, following two situation can be caused: one is compensate excessively, part clashes into bottom electrode, causes part rejection.Serious even can cause damage to robot gripper.Two is compensate deficiency, and part and bottom electrode exist gap, causes that weak weldering/rosin joint/weld quick-fried quality accident of Denging occurs in part.
Summary of the invention
The purpose of this utility model seeks to provide a kind of can do corresponding reasonable compensation to the welding position of robot, it is ensured that the fixing point welder lower electrode wear extent detecting device that part welding is qualified.
For achieving the above object, the fixing point welder lower electrode wear extent detecting device designed by this utility model, including bottom support plate, it is characterised in that: described bottom support plate is provided be arranged in parallel first and transmits guide rail and the second transmission guide rail；Also including the first spring guide pillar and the second spring guide pillar, the lower end of described first spring guide pillar and the second spring guide pillar is transmitted guide rail and second as first respectively and is transmitted in guide rail；The side of described bottom support plate is provided with transmission cylinder and connecting plate, and the output piston bar of described transmission cylinder is connected by the lower end of connecting plate and the first spring guide pillar；
Also including bottom electrode detection plate, the two ends that plate is detected with bottom electrode respectively in the upper end of described first spring guide pillar and the upper end of the second spring guide pillar are connected；The lower surface of described bottom electrode detection plate is provided with displacement detecting plate；Also including displacement transducer, institute's displacement sensors is arranged on bottom electrode workbench and is placed in the lower section of displacement detecting plate.
The utility model has the advantage of: detecting device of the present utility model, can be used in the welding of automatic bolt/nut, the wear extent of detection fixing point welder lower electrode, value is fed back to transfer robot, corresponding reasonable compensation is done in the welding position of robot, it is ensured that part welding is qualified.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fixing point welder lower electrode wear extent detecting device shown in figure, including bottom support plate 1, bottom support plate 1 is provided be arranged in parallel first and transmits guide rail 4.1 and the second transmission guide rail 4.2；Also including the first spring guide pillar 5.1 and the second spring guide pillar 5.2, the lower end of the first spring guide pillar 5.1 and the second spring guide pillar 5.2 is transmitted guide rail 4.1 and second as first respectively and is transmitted in guide rail 4.2；The side of bottom support plate 1 is provided with transmission cylinder 3 and connecting plate 2, and the output piston bar of transmission cylinder 3 is connected with the lower end of the first spring guide pillar 5.1 by connecting plate 2；
Also including bottom electrode detection plate 6, the two ends that plate 6 is detected with bottom electrode respectively in the upper end of the first spring guide pillar 5.1 and the upper end of the second spring guide pillar 5.2 are connected；The lower surface of bottom electrode detection plate 6 is provided with displacement detecting plate 7；Also including displacement transducer 8, displacement transducer 8 is arranged on bottom electrode workbench and is placed in the lower section of displacement detecting plate 7.
Operation principle of the present utility model is as follows: this utility model individually detects the abrasion of bottom electrode.The detection method adopted is at upper electrode installation position displacement sensor, total wear extent of upper/lower electrode detected, by the half of total wear extent, it is used as the wear extent of bottom electrode, this value is fed back to robot, and by the computing of PLC, robot can make corresponding compensation in welding position.Cylinder links with upper electrode, and displacement transducer moves together with upper electrode, detection and distance between bottom electrode.
Testing agency is pushed to the operation interval of electrode by transmission cylinder, now goes up and presses under electrode, and electrode detection plate is displaced downwardly to fits with bottom electrode, drives displacement transducer work, measures the height of bottom electrode.Send the actual value of height and calibration value operation result to robot by network, during robot welding, be automatically adjusted the height of correspondence.
Control system of the present utility model all adopts PLC control, and work process is as follows:
Step one: the piston rod of transmission cylinder 3 stretches out, drives the first spring guide pillar 5.1 and the second spring guide pillar 5.2 to move forward between upper and lower electrode；
Step 2: press under electrode on welding machine, bottom electrode detection plate 6 develops with bottom electrode, and displacement transducer 8 depressed by displacement detecting plate 7；
Step 3: displacement transducer 8 counts；
Step 4: displacement transducer 8 by the numeric feedback that detects to PLC；
Step 5: on welding machine, electrode rises；
Step 6: the piston rod of transmission cylinder 3 is return, drives the first spring guide pillar 5.1 and the second spring guide pillar 5.2 to return.
1. on the welder lower electrode of solid point, install measurement sensor additional, directly detection bottom electrode wear extent in welding.
2., when welding, welding robot, according to actual value and calibration value computing numerical value, is automatically adjusted the height of correspondence.
3. signal is transmitted by network, and capacity of resisting disturbance is strong, by the little the beneficial effects of the utility model of electromagnetic environmental impact:
One, after stopping part and bottom electrode shock, causes the generation of waste product；
They are two years old, it is prevented that part and bottom electrode are not fitted, and cause the generation of defective products.
