The auxiliary equipment for welding of mining machinery and equipment includes a frame and two fixing devices for fixing workpieces. Both of the fixing devices are equipped with angle adjustment devices for changing the angle of the fixing devices. One of the angle adjustment devices is equipped with an X-axial motion device for moving it along the X-axis, and the other angle adjustment device is equipped with a Z-axial motion device for moving it along the Z-axis; the angle and position of the other workpiece are adjusted by another angle adjustment device, the Z-axial motion device and the Y-axial motion device, so that the two workpieces are welded together, and then one of the fixing devices releases the workpiece, and then clamps and fixes the other workpieces for continuous welding. This arrangement can flexibly adjust the position and angle of the parts and has a wide range of applications.

When the telescopic plate contacts the working plate, the telescopic plate will be compressed. When the telescopic plate is compressed, the triangular block will be driven to move.

[0007] According to the above technical solution, a No. 1 spring is arranged between the triangular stopper and the No. 3 slide groove, and the wheel is parallel to the welding head. When the staff pulls up the telescopic sleeve, the triangular stopper will be popped out by the No. 1 spring to continue to limit the telescopic sleeve.

[0008] According to the above technical solution, the telescopic sleeve contacts the triangular stopper, and the triangular block contacts the triangular stopper. When the triangular block moves, the limit on the triangular stopper is released, so that the telescopic sleeve can move downward.

[0010] According to the above technical solution, the blocking block contacts the blocking groove, and the telescopic column contacts the limiting ring. When the blocking block contacts the blocking groove, the parallel frame is limited to prevent the parallel frame from moving at will.

[0011] According to the above technical solution, the inclined block contacts the inclined surface block, and the pushing block contacts the straight plate. The movement of the inclined block will press the inclined surface block, and the movement of the pushing block will push the straight plate.

[0012] The cam is fixedly mounted on a rear portion of the workpiece, and the cam is secured on a rear portion of the workpiece with a clamping plate, a thin straight rod, a thin vertical rod, a dispersing block, a collecting basket, a semi-cylinder, a heat sink, a sliding plate, a block plate, a telescopic rod, a shrinking block and a contact block. The telescopic rod slides through the interior of the working plate. The clamping plate is fixedly mounted on one end of the telescopic rod, the shrinking block is fixedly mounted on the other end of the telescopic rod, the contact block is fixedly mounted on a side of the shrinking block away from the parallel frame, one end of the thin straight rod is fixedly mounted on a side of the parallel frame close to the contact block, the thin vertical rod is fixedly mounted on the top of the other end of the thin straight rod, the dispersing block is rotatably mounted on the top of the thin vertical rod, the collecting basket is fixedly mounted on the right side of the frame, the heat sink is fixedly mounted on the back side of the collecting basket, the sliding plate is fixedly mounted on the top of the collecting basket, the block plate is fixedly mounted on the top of the collecting basket, and the semi-cylinder is fixedly mounted on the top of the sliding plate.

[0013] According to the above technical solution, the working plate contacts the semi-cylinder, and the loosening block contacts the contact block. When the working plate contacts the semi-cylinder, vibration will be generated to remove iron filings on the weld, and the loosening block will loosen the contact block.

[0014] The present invention provides an auxiliary device for welding mining machinery and equipment. It has the following beneficial effects: (1) In the invention, the limiting column and the telescopic sleeve move. When the telescopic plate contacts the working plate, the telescopic plate will be compressed. When the telescopic plate is compressed, the triangular block will be driven to move. When the triangular block moves, the triangular stopper on the limiting column will be squeezed. When the workpiece is being welded, the sparks and spatters generated during the welding process can be effectively reduced. When the wheel moves, the soft iron sheet will be driven to move, which can help the staff to better align the welding head with the weld. At the same time, the soft iron sheet can also remove the iron filings from the weld just after welding.

[0015] (2) In this invention, when the pressure block is not in contact with the inclined block, the working plate will shake up and down on the telescopic column, which is beneficial to the subsequent vibration removal of iron chips. When the straight plate moves, it will push the wide and narrow plates to move. When the wide and narrow plates move, they will drive the positioning blocks to limit the parallel frames on the straight cylinders. The fixation of the workbench can greatly improve the welding process and prevent unnecessary damage to the objects due to careless touch by the workers during the welding process.

[0016] (3) In the invention, when the clamping plate moves, it drives the telescopic rod to move, and when the telescopic rod moves, it drives the shrinking block to move, and when the shrinking block moves, it drives the contact block to move. When the contact block moves to the position of the thin straight rod, the restriction on the shrinking block can be loosened to shorten the time for workers to replace the objects that have just been processed. When the working plate moves to the sliding plate, it will contact the semi-cylinder. When the working plate contacts the semi-cylinder, it will vibrate. When the working plate vibrates, the iron chips generated by the object during welding will be shaken off, and the heat sink above will blow the iron chips into the collection basket. When the iron chips are blown, they will be blocked by the block plate and fall into the collection box. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The blocking block 905 contacts the blocking groove, and the telescopic column 910 contacts the limiting ring 907. When the blocking block 905 contacts the blocking groove, the parallel frame 6 is limited to prevent the parallel frame 6 from moving at will.

[0025] The inclined block 900 contacts the inclined surface block 901 , and the pushing block 902 contacts the straight plate 903 . The movement of the inclined block 900 will press the inclined surface block 901 , and the movement of the pushing block 902 will push the straight plate 903 .

[0026] The collecting mechanism comprises a clamping plate 001, a thin straight rod 002, a thin vertical rod 003, a dispersing block 004, a collecting basket 005, a semi-cylinder 006, a heat sink 007, a sliding plate 008, a stop plate 009, a telescopic rod 010, a shrinking block 011 and a contact block 012.

It can greatly shorten the time for staff to replace objects that have just been processed. When the working plate moves to the semi-cylinder 006, it will vibrate, and the iron filings generated by the object during welding will be shaken off. At the same time, the heat sink 007 will dissipate heat for the object to prevent the iron filings from sticking to the weld after cooling, which will affect the subsequent use of the workpiece and affect the subsequent work.

[0027] The working plate 5 contacts the semi-cylinder 006 , and the loosening block 004 contacts the contact block 012 . When the working plate 5 contacts the semi-cylinder 006 , vibration will be generated to remove iron filings on the weld, and the loosening block 004 will loosen the contact block 012 .

[0028] When this embodiment is working: adjust the machine column 2 on the frame 1, start the mover 3 to move the working plate 5 toward the collecting basket 005, start the rotator 4 to align the object with the welding head 7, when the machine column 2 moves, it will drive the telescopic plate 801, the limiting column 802 and the telescopic sleeve 803 to move, when the telescopic plate 801 contacts the working plate 5, the telescopic plate 801 will be compressed, when the telescopic plate 801 is compressed, it will drive the triangular block 804 to move, when the triangular block 804 moves, it will squeeze the triangular stopper 805 on the limiting column 802, when the triangular stopper 805 is squeezed, it will move It slides in the No. 3 slide groove. When the triangular stopper 805 moves, the limit on the telescopic sleeve 803 will be released. When the limit of the telescopic sleeve 803 is released, it will bounce downward to cover the object and the welding head 7 to prevent sparks from flying and causing harm to the staff. When the telescopic plate 801 moves, it will drive the wheel 806 to move. When the wheel 806 moves, it will drive the soft iron sheet 807 to move. When the soft iron sheet 807 contacts the object, the iron filings on the top will be shoveled away. When the telescopic sleeve 803 moves, it will drive the straight column 808 to move. When the straight column 808 moves, it will drive the pressing block 809 to move.

[0029] Starting the rotator 4 will drive the gear ring 909 to rotate, and the rotation of the gear ring 909 will drive the telescopic column 910 to rotate. When the telescopic column 910 rotates, it will drive the working plate 5 to rotate. When the working plate 5 is adjusted, it will be moved to the cutting position. When the pressing block 809 moves, the inclined block 900 will be pressed downward. When the inclined block 900 moves, the inclined surface block 901 will be pressed. When the inclined surface block 901 moves, the pushing block 902 will be driven to move. When the pushing block 902 moves, the straight plate 903 will be pushed. When the straight plate 903 moves, the wide and narrow plate 904 will be pushed. When the wide and narrow plate 904 moves, the positioning block 905 will be driven to the parallel frame 6 on the straight cylinder 908 When the wide and narrow plates 904 move, the push plate 906 will be pushed to move. When the push plate 906 moves, the limit ring 907 will be pushed to move in the sixth slide groove toward the telescopic column 910. Because when the limit ring 907 contacts the telescopic column 910, the friction between the limit ring 907 and the telescopic column 910 will increase, which can make the telescopic column 910 unable to rotate, thereby ensuring the welding accuracy of the workpiece on the working plate 5. When the pressure block 809 moves, it will squeeze the rotating plate 911. When it is pressed to a certain extent, the rotating plate 911 will rebound quickly, driving the folding plate 912 to move. When the folding plate 912 moves, it will drive the collision block 913 to quickly hit the object.

[0030] Start the heat sink 007. When the object is clamped by the clamping plate 001, the contraction block 011 is twisted upward to make the telescopic rod 010 contract upward to fix the clamping plate 001. When the working plate 5 moves, the clamping plate 001 will be driven to move. When the clamping plate 001 moves, the telescopic rod 010 will be driven to move. When the telescopic rod 010 moves, the contraction block 011 will be driven to move. When the contraction block 011 moves, the contact block 012 will be driven to move. When the contact block 012 moves to the position of the thin straight rod 002, it will contact the movable block 004 on the thin vertical rod 003 to make the contraction block 011 rotate in the opposite direction, thereby loosening the clamping plate 001. When the working plate 5 moves to the sliding plate 008, it will contact the semi-cylinder 006 to generate vibration. When the staff pushes the object to the collection basket 005, it will be blocked by the block plate 009 and fall into the collection basket 005 below.
