Technical Field

The utility model relates to the technical field of spot welding equipment, in particular to a novel high-efficiency spot welding table capable of preventing welding spot deviation.

Background Art

Spot welding refers to a welding method that uses a cylindrical electrode to form a weld between the contact surfaces of two overlapping workpieces. During spot welding, pressure is first applied to make the workpieces in close contact, and then the current is turned on. The contact between the workpieces melts under the action of resistance heat, and the weld is formed after cooling. Spot welding is mainly used for welding of sheet metal stampings with a thickness of less than 4mm, and is particularly suitable for welding automobile bodies, carriages, and aircraft fuselages. However, it cannot weld containers that require sealing.

In order to ensure a tight connection between workpieces, a large number of welding spots are required to maintain a stable connection between workpieces when spot welding the workpieces. In some small chemical plants, manual handheld clamps are mostly used to complete the welding of workpieces when spot welding welding products. Due to the large number of welding spots, it is more laborious for employees to hold the clamps for welding, and the welding position is easily offset, resulting in incorrect welding spot positions, resulting in unqualified or scrapped products. Therefore, a new type of high-efficiency spot welding station with anti-welding spot offset is proposed to solve the above problems.

Please refer to Figures 1-5, a novel high-efficiency spot welding station for preventing solder joint deviation in this embodiment includes a positioning plate 16;

A connecting seat 6 is supported on the upper end surface of the positioning plate 16. The connecting seat 6 is L-shaped and a third stopper 5 is installed on one side of its upper part. The top surface of the third stopper 5 is arranged horizontally with the connecting plate 1; a second insulating plate 11 is installed on the upper end surface of the positioning plate 16, and an insulating sleeve 14 is inserted into the second insulating plate 11 and fixed to the upper end surface of the positioning plate 16 through the insulating sleeve 14; a connecting block 10 is installed on the upper end surface of the second insulating plate 11, and a plurality of second insulating sleeves 15 are inserted into the connecting block 10. A third insulating plate 13 is installed on one side of the connecting block 10, and the third insulating plate 13 is arranged between the connecting seat 6 and the connecting block 10. A fourth stopper 12 is installed on the other side of the connecting block 10, and the fourth stopper 12 is arranged perpendicular to the positioning plate 16.

An insulating plate 9 is installed on the lower end surface of the positioning plate 16, and the lower end surface of the insulating sleeve 14 passes through the positioning plate 16 and extends to the bottom of the positioning plate 16 and the end is connected to the bottom connecting seat 7. A first stopper 3 is also installed on the side of the positioning plate 16 away from the connecting seat 6.

In this embodiment, by installing the second insulating plate 11 and the bottom connecting seat 7, the overall static electricity of the spot welding table can be reduced during the actual spot welding process to prevent the static electricity attached to the table surface from injuring the operator during spot welding. At the same time, by blocking the travel of the connecting plate 1 between the first stopper 3 and the third stopper 5, the failure of spot welding caused by excessive sliding distance of the connecting plate 1 during sliding spot welding can be avoided.

Please refer to Figure 1. In order to reduce the labor of manually holding the clamp to weld the workpiece and improve the welding accuracy and welding quality, the upper end surface of the positioning plate 16 in this embodiment is provided with a mounting plate 2; the upper end surface of the mounting plate 2 is provided with two sets of linear guide rails 21 along its horizontal direction; a slider is slidably provided on the linear guide rail 21, and a connecting plate 1 is installed on the slider; a positioning shaft 17 is provided on the lower end surface of the mounting plate 2, and a spring is sleeved on the outer side of the positioning shaft 17, and a hole is opened on the side ear plate of the positioning plate 16 for the positioning shaft 17 to pass through, and the lower end of the positioning shaft 17 extends and is inserted into the side connecting block 18; a second stopper 4 is installed on the lower end surface of the side connecting block 18, and a plurality of positioning pin holes are opened on the connecting plate 1, and pins 8 are inserted into the positioning pin holes; slots are opened on the connecting plate 1 and the positioning plate 16.

In this embodiment, in actual use, a positioning plate 16 is installed at the lower electrode plate of the spot welding equipment, and the ear plate on the mounting plate 2 is plugged in with the positioning shaft 17 and the side connecting block 18 to complete the installation of the mounting plate 2 on the positioning plate 16. Through the cooperation between the two sets of linear guides 21 set on the mounting plate 2 and the connecting plate 1, when the fixture is fixed on the connecting plate 1 by a plurality of positioning bolts, the sliding of the linear guide 21 on the connecting plate 1 is utilized to cooperate with the operator to hold the fixture to weld the workpiece. When the operator pushes the fixture, it is restricted by the linear guide 21, and the fixture and the workpiece will always maintain a straight line movement, thereby completing the stable welding of the workpiece. The linear guide 21 is positioned and fixed by 4*M10 bolts, and the installation method should be kept perpendicular to the electrode rod, thereby ensuring that the workpiece and the welding point are always in horizontal movement, realizing precise control of the welding point, and the welding point position is achieved by changing the plug-in switching of the pin 8 on the connecting plate 1 to realize the installation of the fixture at different positions, thereby ensuring that the position of each welding point remains consistent.

Please refer to Figures 1 and 2. In order to quickly know the welding stroke distance during welding, two ear plates are protruding on both sides of the positioning plate 16 in this embodiment, and side connecting blocks 18 are installed on the lower end faces of the four ear plates. A ruler 19 is installed on the side faces of the two side connecting blocks 18 on the same side; a number of scale lines 20 are engraved on the ruler 19.

In this embodiment, in actual welding work, by setting the scale 19 on both sides of the side connecting block 18, the operator can directly observe the stroke distance of the current welding spot welding when performing sliding spot welding on the clamp, and then control the welding stroke, thereby further improving the efficiency and accuracy of welding, and there is no need for the staff to perform additional operations, and the operation is simple.

The working principle of the above embodiment is:

The first step is to install the positioning plate 16 at the lower electrode plate of the spot welding equipment, and at the same time, use the plug-in cooperation between the ear plate on the mounting plate 2 and the positioning shaft 17 and the side connecting block 18 to complete the installation of the mounting plate 2 on the positioning plate 16. Through the cooperation between the two sets of linear guides 21 set on the mounting plate 2 and the connecting plate 1, when the fixture is fixed on the connecting plate 1 through multiple positioning bolts, the sliding of the linear guide 21 on the connecting plate 1 is used to realize the linear push of the fixture, and then cooperate with the electrode rod to realize the linear spot welding of the workpiece on the fixture. The linear guide 21 is positioned and fixed by 4*M10 bolts, and the welding point position is achieved by changing the plug-in switching of the pin 8 on the connecting plate 1 to realize the installation of the fixture at different positions, thereby ensuring that the position of each welding point remains consistent. By opening a notch at the bottom of the connecting plate 1 to avoid the lower electrode rod, when the electrode cap is worn, through the mounting plate 2 The four springs on the side ensure compensation for the wear of grinding. The stroke of the spring is 10mm. The installation method of the connecting plate 1 is perpendicular to the electrode rod. By installing the clamp on the connecting plate 1 and cooperating with the linear guide 21 to give the connecting plate 1 sliding positioning, during spot welding, the position of the clamp is limited by the linear guide 21 and is always in linear movement. At the same time, with the observation of the ruler 19, the operator is always in linear welding when welding the workpiece on the clamp. Therefore, during welding, there will be no quality problems such as horseshoe points and edge welds caused by the offset of the welding angle due to the holding of the clamp before. At the same time, the clamp is fixed by the sliding connecting plate 1. After welding by sliding, it is convenient for employees to operate welding, saving employees' welding time and improving welding production efficiency. The welding rhythm is increased from 150 points per hour to 200 points.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
