Description

Technical Field

[0001] This utility model relates to the field of electrode grinding technology, specifically to an electrode grinding mechanism. Background Technology

[0002] After a period of use, welding machine electrodes will deform and oxidize. Electrode regrinding can remove oxides, dirt and wear layers from the electrode surface, ensuring good contact between the electrode and the workpiece during welding, thereby obtaining consistent welding results and higher welding quality. At the same time, regular electrode regrinding can slow down the wear rate of the electrode, extend the service life of the electrode, reduce the frequency of electrode replacement, and thus save costs.

[0003] A search revealed that utility model patent CN217800917U discloses a spot welding electrode grinding machine, comprising a grinding machine and a column. A slot is formed on the upper surface of the outer wall of the column, and a base is installed at the bottom of the column. A positioning mechanism is installed on the upper surface of the outer wall of the column. The structure is reasonable; by providing a positioning mechanism, it is installed on the outer wall of the column on the grinding machine. Utilizing the height-adjustable and elastically fixed effect of the positioning mechanism, when the height of the grinding components on the positioning mechanism needs to be adjusted, the height of the grinding components on the outer wall of the column can be moved according to the operator's needs, and then elastically fixed. This effectively solves the problem of cumbersome disassembly and assembly caused by the need for fastening bolts after the grinding components have been adjusted. This makes the spot welding electrode grinding machine easy to adjust and position, improving its performance.

[0004] However, the above patent still has the following shortcomings: although the height of the grinding machine can be adjusted, it can only be fixed at a few heights corresponding to the slot, which is not very practical; in addition, a certain amount of copper shavings will be generated when grinding the electrode, and it is not convenient to completely collect the copper shavings by the cutting disc alone. Therefore, we have proposed an electrode grinding mechanism. Utility Model Content

[0027] In this embodiment, the lifting seat 5 is limited by the movable sleeve between the column 2 and the lifting seat 5, so that the lifting seat 5 can only move along the axial direction of the lead screw 4. In addition, the electrode grinder 10 is the prior art. The electrode grinder 10 includes two grinding tool holders so that the tools on the two grinding tool holders can grind the vertical and horizontal electrodes.

[0028] For details, please refer to Figure 1 , Figure 2 and Figure 4 The dust collection mechanism 9 includes a collection box 12 fixedly connected to the top surface of the support plate 8. A suction pump 13 is fixedly installed at one end of the collection box 12. The input end of the suction pump 13 extends into the inner cavity of the collection box 12. A shaping hose 14 is fixedly sleeved at the other end of the collection box 12. A dust collection cover 15 is fixedly connected to the end of the shaping hose 14. A filter screen 16 is fixedly sleeved in the inner cavity of the collection box 12.

[0029] In this embodiment, the shaped hose 14 can be used to pull the dust suction cover 15 to the side of the motor grinding area so that the suction force of the dust suction cover 15 can be used to suck the copper dust generated during grinding into the inner cavity of the collection box 12 for collection.

[0030] For details, please refer to Figure 2The end of the lifting seat 5 is provided with a slot 21 and multiple mounting holes 22. The end of the connecting seat 6 is movably sleeved into the inner cavity of the slot 21 and is provided with multiple screw holes 23. The inner cavity of the mounting hole 22 is fitted with a bolt 24, and the bottom end of the bolt 24 is threaded into the inner cavity of the screw hole 23.

[0031] In this embodiment, the L-shaped bracket 7 is installed on the lifting seat 5 by the cooperation of the slot 21, mounting hole 22, screw hole 23 and bolt 24.

[0032] For details, please refer to Figure 3 A push handle 18 is fixedly connected to the top surface of the base plate 1, and a control panel 19 is fixedly installed on the push handle 18.

[0033] In this embodiment, the device is pushed by holding the push handle 18, and the device is controlled by the control panel 19.

[0034] For details, please refer to Figure 2 Multiple self-locking casters 11 are fixedly installed on the bottom surface of the base plate 1.

[0035] In this embodiment, the self-locking casters 11 are used to support the mechanism, and the self-locking casters 11 are used to drive the device to move. The self-locking function of the self-locking casters 11 can be used to fix the position of the mechanism.

[0036] For details, please refer to Figure 4 The outer side of the collection box 12 is hinged with a sealing door 17.

[0037] In this embodiment, the copper shavings collected in the collection box 12 are cleaned by opening the sealed door 17.

[0038] Working principle: In use, first, hold the push handle 18 to push the mechanism, and use the self-locking casters 11 to move the mechanism. At the same time, start the brake motor 20 to drive the lead screw 4 to rotate. Through the threaded engagement between the lead screw 4 and the lifting seat 5, the lifting seat 5 moves up and down. The lifting seat 5 drives the electrode grinder 10 to move up and down synchronously, so that the end of the motor to be ground is inserted into the tool on the electrode grinder 10. Then, pull the chip suction cover 15 to stretch the shaping hose 14, so that the chip suction cover 15 is placed on the side of the electrode to be ground. Finally, use the electrode grinder 10 to grind the electrode. At the same time, start the suction pump 13 to draw air into the inner cavity of the collection box 12. The negative pressure in the inner cavity of the collection box 12 causes the shaping hose 14 and the chip suction cover 15 to generate suction. The suction of the chip suction cover 15 sucks the copper chips generated during electrode grinding into the inner cavity of the collection box 12. The filter screen 16 intercepts the copper chips in the inner cavity of the collection box 12.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
