DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] like Figure 1 The fixture shown is suitable for grinding various types of butt welding electrode tips, and includes a length adjustment device 11, a height adjustment device 12 and an angle adjustment device 13.

[0030] There are five height adjustment devices 12 , which are arranged side by side above the angle adjustment device 13 , and the height adjustment device 12 as a whole can rotate along with the angle adjustment device 13 to adjust the angle.

[0031] There are five length adjustment devices 11, which are arranged side by side and correspond one to one above the multiple height adjustment devices 12, and each length adjustment device 11 can be moved and adjusted in height along with the corresponding height adjustment device 12 below.

[0032] The length adjustment device 11 can adjust the extension length of the electrode tip and thus adjust the grinding length of the electrode tip.

[0033] like Figure 2 As shown, the length adjustment device 11 includes a length adjustment seat body 111, a top screw 112 and an adjusting bolt 114. The length adjustment seat body 111 is connected to the top of the height adjustment device 12 by a fixing bolt 113, and adaptation to multiple electrode head products is achieved by replacing different types of electrode head grinding length adjustment devices. An inner cavity that is adapted to the outer contour of the electrode head is provided in the length adjustment seat body 111, and the tail end of the electrode head is inserted into the inner cavity of the length adjustment seat body 111. The adjusting bolt 114 is tightened to the tail end of the electrode head through a threaded hole, and the grinding length of the electrode head is adjusted by moving the adjusting bolt back and forth. After the grinding length adjustment is completed, the electrode head body is locked by the top screw 112 at the top of the length adjustment seat body 111.

[0034] like Figure 3 As shown, the height adjustment device 12 includes a height adjustment seat body 121, a wedge-shaped height adjustment block A122, a wedge-shaped height adjustment block B123, a height adjustment knob 124, a fastening bolt 125, a fixing screw and a spring 127.

[0035] The bottom of the height adjustment seat body 121 is hollowed out and placed on the bottom plate 126. The wedge-shaped height adjustment block A122 is arranged in the height adjustment seat body 121 and is fixedly connected to the height adjustment seat body 121 by fixing screws, and the inclined surface of the wedge-shaped height adjustment block A122 faces downward. The wedge-shaped height adjustment block B123 is arranged in the height adjustment seat body 121 and placed on the bottom plate 126. The inclined surface of the wedge-shaped height adjustment block B123 faces upward and fits with the inclined surface of the wedge-shaped height adjustment block A122. The height adjustment knob 124 is arranged on the height adjustment seat body 121 on one side of the wedge-shaped height adjustment block B123. The height adjustment knob 124 pushes the wedge-shaped height adjustment block B123 forward to squeeze the wedge-shaped height adjustment block A122, thereby adjusting the height of the height adjustment seat body 121, and then driving the overall height of the electrode head.

[0036] There are multiple fastening bolts 125, the head of the fastening bolt 125 is a threaded part, and the rest is a smooth surface. The head of the fastening bolt 125 passes through the base plate 126 from bottom to top and is fixedly connected to the height adjustment seat body 121 through the threaded part of the head. A spring 127 is sleeved on the smooth surface of the fastening bolt 125 between the bolt head at the tail of the fastening bolt 125 and the base plate 126. The elastic force of the spring 127 pulls the height adjustment device 12 down as a whole and close to the base plate 126.

[0037] like Figure 4 As shown, there are two angle adjustment devices 13, which are symmetrically arranged below the two sides of the base plate 126. The angle adjustment device 13 includes a semicircular dial 131, a screw 133, a fixing seat 134 and a positioning pin bracket 135. The arc surface of the semicircular dial 131 faces downward, and a gear 132 is provided on the arc surface. The screw 133 is provided below the semicircular dial 131, and the screw 133 is engaged with the gear 132. The rotation of the screw 133 drives the dial 131 to rotate and adjust the angle. There are two positioning pin brackets 135 symmetrically arranged on both sides of the semicircular dial 131, and a positioning pin is connected between the two positioning pin brackets 135. An arc groove is provided on the semicircular dial 131, and the positioning pin is provided in the arc groove. Both sides of the bottom plate 126 are respectively fixed above the two semicircular scale plates 131 of the angle adjustment devices 13 , so that the bottom plate 126 rotates with the scale plates 131 to adjust the angle.

[0038] The working principle is to place the electrode tip into the electrode tip grinding length adjustment device. Turn the tail bolt to adjust the tip of each electrode tip to the same height, then tighten the top screw to lock the electrode tip. After the electrode tip length is adjusted, turn the worm of the electrode tip grinding angle adjustment device to adjust the electrode tip angle parallel to the grinding wheel. Once the electrode tip grinding surface is parallel to the grinding wheel, use the bolts to push the wedge-shaped height adjustment block up and down to adjust the grinding surface of each electrode tip to the same height. After adjustment, begin grinding the electrode tip. After grinding is completed, loosen the top screw and remove it, completing the grinding process.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
