Description

Technical Field

[0001] The utility model relates to a grinding device, in particular to a grinding device for a welding gun electrode cap. Background Art

[0002] The welding gun electrode cap grinding machine is a device specially used for grinding the welding gun electrode cap. During the welding process, the welding gun electrode cap will gradually wear out due to high temperature, friction and other factors. In order to ensure the welding quality and efficiency, the electrode cap needs to be regularly ground.

[0003] At present, when the welding gun electrode cap grinding machine is used, the welding gun electrode cap grinding machine is manually fixed on the ground, and then the robot grabs the welding gun and grinds the welding gun electrode cap at a fixed position. With the optimization of production lines, the welding gun is installed on a fixed frame, and the robot grabs the workpiece and grinds it on the welding gun.

[0004] However, the prior art has the following technical problems during use:

[0005] (1) When the robot grabs the workpiece onto the welding gun, it is necessary to manually pause the grinder and change the position of the grinder before the robot can grab the workpiece. Therefore, manual entry into the production line during the grinding process not only affects the production line's operating efficiency, but also consumes a lot of manpower and time.

[0006] (2) When the grinder is not working, the position of the grinder is changed manually. Since the grinder has a certain weight, it is easy to swing. During the swinging process, it is easy for the grinder to hit the welding gun head, thereby causing damage to the grinder or welding gun.

[0007] Therefore, there is an urgent need for a grinding device for the welding gun electrode cap that can solve the above problems. Summary of the invention

[0008] The utility model overcomes the shortcomings of the prior art and provides a grinding device for a welding gun electrode cap. To achieve the above purpose, the utility model adopts a technical solution as follows: a grinding device for a welding gun electrode cap, comprising: a driving mechanism, an adjusting mechanism connected to the driving mechanism, a rotating shaft, a swing arm, a grinding mechanism, and a floating mechanism connected to the grinding mechanism.

[0009] In a preferred embodiment of the utility model, the adjustment mechanism includes a first rotating rod, a second rotating rod, and a connecting rod connecting the first rotating rod and the second rotating rod; the connecting rod includes a sleeve rod and a retractable rod; the retractable rod can slide in the sleeve rod, and the two ends of the retractable rod are respectively rotatably connected to the first rotating rod and the second rotating rod, and one end of the second rotating rod is connected to the swing arm rod through the rotating shaft.

[0010] In a preferred embodiment of the utility model, the grinding mechanism is installed at the swing arm rod, and the grinding mechanism can slide on the swing arm rod.

[0011] In a preferred embodiment of the utility model, the floating mechanism includes a guide rod, a slider, a spring and a cylinder; the slider is slidably connected to the guide rod, the spring is provided on one side of the slider, the cylinder drives the slider to slide on the guide rod, and the grinding mechanism is connected to the spring.

[0012] In a preferred embodiment of the utility model, the grinding mechanism comprises a grinding machine and a floating seat; the grinding machine is installed at the floating seat, and both ends of the floating seat are connected to the spring.

[0013] In a preferred embodiment of the utility model, the driving mechanism includes a driving motor and a reducer; the driving motor is connected to the reducer, and the reducer is connected to the first rotating rod.

[0014] In a preferred embodiment of the present invention, the length of the second rotating rod is greater than the length of the first rotating rod.

[0015] In a preferred embodiment of the utility model, the driving mechanism and the adjusting mechanism are both installed on the base, and the swing arm is located on one side of the driving mechanism.

[0016] In a preferred embodiment of the utility model, the minimum value of the angle formed between the swing arm and the base is 20° to 30°.

[0017] In a preferred embodiment of the present invention, the maximum value of the angle formed between the swing arm and the base is 100° to 110°.

[0018] In a preferred embodiment of the utility model, the grinding mechanism and the swing arm are relatively parallel.

[0019] In a preferred embodiment of the utility model, the guide rod, the sliding block and the spring are provided in two groups, and are respectively arranged on both sides of the floating seat.

[0020] The utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0021] (1) By providing a driving mechanism, an adjusting mechanism, a swing arm, and a grinding mechanism, when in use, the swing arm is under the action of the driving mechanism and the adjusting mechanism, so that the grinding mechanism can move back and forth on the swing arm, which can not only meet the grinding work of the welding machine electrode cap, but also achieve effective avoidance, so that it is convenient for the welding gun to grab the workpiece for welding, thereby improving the production line start-up efficiency and reducing the labor cost consumed by grinding. Thus, the problems of low production line start-up efficiency and serious labor consumption in the prior art are solved.

[0022] (2) By providing a guide rod, a slider, a spring and a cylinder, when in use, the spring floating mechanism driven by the cylinder can effectively prevent the grinder from colliding with the welding gun head during the movement of the swing arm, thereby preventing the grinder or the welding gun head from being damaged.

Under the action of the driving mechanism and the adjustment mechanism, the swing arm 3 realizes the reciprocating motion of the grinding mechanism 4 on the swing arm 3, so that it can not only meet the grinding work of the welding machine electrode cap, but also realize effective avoidance, so that it is convenient for the welding gun to grab the workpiece for welding, thereby improving the production line start-up efficiency and reducing the labor cost consumed by grinding.

[0042] In one embodiment, the driving mechanism 1 comprises a driving motor 1.1 and a reducer 1.2; the driving motor 1.1 is connected to the reducer 1.2, and the reducer 1.2 is connected to the first rotating rod 2.1. The length of the second rotating rod 2.3 is greater than that of the first rotating rod 2.1.

[0043] In one embodiment, the length of the second rotating rod 2.3 is preferably 1.5 times the length of the first rotating rod 2.1.

[0044] like Figure 3 and Figure 4 As shown, the driving mechanism 1 and the adjusting mechanism 2 are both installed at the base, and the swing arm 3 is located at one side of the driving mechanism 1. The grinding mechanism 4 is installed at the swing arm 3, and the grinding mechanism 4 can slide on the swing arm 3.

[0046] In one embodiment, the maximum angle formed between the swing arm 3 and the base is 100° to 110°. In one embodiment, the maximum angle formed between the swing arm 3 and the base is preferably 100°. This can effectively prevent the grinder 4.1 from colliding with the welding gun head during the movement of the swing arm 3, thereby preventing the grinder 4.1 or the welding gun head from being damaged.

[0047] In one embodiment, the grinding mechanism 4 is relatively parallel to the swing arm 3. The guide rod 6.1, the slide block 6.2 and the spring 6.3 are each provided in two groups, and are respectively provided on both sides of the floating seat 4.2.

At the same time, during the adjustment process, the slider 6.2 and the spring 6.3 can reduce the impact force of the grinding machine 4.1 during the movement, thereby avoiding the grinding machine 4.1 from colliding with the welding gun head.
