Technical Field

[0001] The present application relates to the technical field of welding, and in particular to an automatic grinding device for a roller welding electrode wheel. Background Art

[0002] Welding is a commonly used method for connecting metals. Roller welding (also known as projection welding) is a type of resistance welding, mainly used for welding and fixing two welding tapes (also known as workpieces).

[0003] In the prior art, a roller welding machine is used to complete the roller welding of two welding tapes (metal thin tapes). The roller welding machine includes a frame, a cylinder and an electrode wheel arranged on the frame. The electrode wheel includes two relatively arranged first electrode wheels and a second electrode wheel. The first electrode wheel is fixedly arranged on the frame, the cylinder is fixedly arranged on the frame, the second electrode wheel is arranged on the driving end of the cylinder, and the cylinder drives the second motor wheel to approach or move away from the second motor wheel.

[0004] When the roller welding machine welds two welding tapes, the two welding tapes are arranged between the first electrode wheel and the second electrode wheel. The cylinder drives the second electrode wheel to move towards the first electrode wheel, so that the first motor wheel and the second motor wheel squeeze the welding tape. The welding tape advances driven by the roller, and the current is connected intermittently, and finally a resistance welding of a continuous weld seam is completed.

[0005] However, during the process of welding the workpiece by the electrode wheel, some welding slag will adhere to the electrode wheel. Therefore, when the electrode wheel rolls and presses the workpiece for welding, it will affect the welding quality of the workpiece. Summary of the Utility Model

[0006] In order to improve the welding quality of the roller welding of the welding tape, the present application provides an automatic grinding device for a roller welding electrode wheel.

[0007] The automatic grinding device for a roller welding electrode wheel provided by the present application adopts the following technical solutions:

[0008] An automatic grinding device for a roller welding electrode wheel, the automatic grinding device is installed on the frame of the roller welding machine, and the automatic grinding device is used to grind the welding slag on the surface of the electrode wheel; it includes a linear reciprocating driving member along the axial direction of the electrode wheel, a mounting platform and a grinding assembly; the linear reciprocating driving member is fixedly arranged on the frame of the roller welding machine, the mounting platform is fixedly arranged on the driving end of the linear reciprocating driving member, the grinding assembly is fixedly arranged on the side of the mounting platform away from the linear reciprocating driving member, and the grinding assembly includes a grinding wheel and a grinding wheel frame; the grinding wheel frame is fixedly arranged on the mounting platform, the grinding wheel is installed on the grinding wheel frame, and the linear reciprocating driving member drives the grinding wheel to linearly reciprocate along the axial direction of the electrode wheel to grind the welding slag on the electrode wheel.

[0009] By adopting the above technical solution, when the electrode wheel rolls and welds the welded parts, the driving end of the linear reciprocating driving member drives the grinding assembly to move radially towards the electrode wheel, so that there is a small avoidance gap between the grinding wheel and the electrode wheel; thus, when the electrode wheel is adhered with welding slag, the grinding wheel can grind the welding slag on the electrode wheel to clean the welding slag and other impurities on the electrode wheel; thereby improving the welding quality of the two welded parts, reducing the damage to the electrode wheel at the same time, and prolonging the service life of the electrode wheel.

The motor is fixedly arranged on the side of the mounting platform away from the linear reciprocating driving member. The grinding wheel is rotatably connected to the grinding wheel frame. The transmission belt is sleeved on the grinding wheel and the motor. The motor drives the grinding wheel to rotate through the transmission belt.

[0011] By adopting the above technical solution, the motor drives the grinding wheel to rotate through the transmission belt, so that the rotating grinding wheel can grind the welding slag adhered to the electrode wheel, which can improve the cleaning effect of the grinding assembly on the welding slag.

[0013] By adopting the above technical solution, an elastic member is arranged between the first mounting plate and the second mounting plate, so as to endow the mounting platform with a certain flexible deformation ability.

[0022] Optionally, the linear reciprocating driving member is a hand-operated screw jack.

[0023] By adopting the above technical solution, the staff can move the grinding assembly by manually rotating the handwheel of the hand-operated screw jack, thereby facilitating the staff to accurately control the moving position of the grinding assembly.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When the electrode wheel rolls and welds the welded part, the driving end of the linear reciprocating driving member drives the grinding assembly to reciprocate axially along the electrode wheel, so that there is a small clearance between the grinding wheel and the electrode wheel; thus, when there is welding slag adhered to the electrode wheel, the grinding wheel can grind the welding slag on the electrode wheel to clean the welding slag and other impurities on the electrode wheel; thereby improving the welding quality of the two solder tapes, reducing the damage to the electrode wheel at the same time, and prolonging the service life of the electrode wheel;

[0026] 2. The motor drives the grinding wheel to rotate through a transmission belt, so as to use the rotating grinding wheel to grind the welding slag adhered to the electrode wheel, which can improve the cleaning effect of the grinding assembly on the welding slag;

[0027] 3. By providing an elastic member between the first mounting plate and the second mounting plate, a certain flexible deformation ability is imparted to the mounting platform. Thus, when the welding slag is large and the adhesion strength between the welding slag and the electrode wheel is high, the adjustable flexible deformation ability of the mounting platform can be utilized to enable the grinding wheel to move slightly. The grinding wheel can apply a radial pressure to the welding slag, improving the grinding effect of the grinding wheel on the welding slag. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following Figures 1-4 further elaborates on this application in conjunction with the attached

[0034] This application embodiment discloses an automatic grinding device for a roll welding electrode wheel. Referring to Figure 1 , the automatic grinding device for the roll welding electrode wheel is used on the seam welder 1. Since the seam welder 1 is not the main inventive point of this application and there are many specific implementation manners of the seam welder 1 in the prior art, this application does not describe the specific structure of the seam welder 1 in detail, but only describes the main structure of the seam welder 1 to assist in explaining the working principle of the automatic grinding device of this application.

[0035] Referring to Figure 1, the seam welder 1 includes a frame 11, and electrode wheels 12 disposed on the frame 11. The electrode wheels 12 include two relatively arranged first electrode wheels 121 and second electrode wheels 122. When the seam welder 1 welds two welding tapes 2 (metal thin tapes, also known as workpieces), the two welding tapes 2 are disposed between the first electrode wheel 121 and the second electrode wheel 122. The first motor wheel and the second motor wheel squeeze the welding tape 2, and the welding tape 2 advances driven by the rollers. The current is switched on intermittently, and finally a resistance weld of a continuous weld seam is formed. However, during the process of welding the welding tape 2 by the electrode wheels 12, some welding slag will adhere to the electrode wheels 12. Thus, when the electrode wheels 12 roll and press the welding tape 2 for welding, the welding quality of the welding tape 2 will be affected. An automatic grinding device in this application is used to clean the welding slag on the electrode wheels 12.

[0036] Referring to Figure 1 , the automatic grinding device for the roller welding electrode wheels is installed on the frame 11 of the seam welder 1. The automatic grinding device includes a linear reciprocating drive member 3 along the axial direction of the electrode wheel, a mounting platform 4, and a grinding assembly 5. The linear reciprocating drive member 3 is fixedly disposed on the frame 11 of the seam welder 1, the mounting platform 4 is fixedly disposed at the drive end of the linear reciprocating drive member 3, and the grinding assembly 5 is fixedly disposed on the side of the mounting platform 4 away from the linear reciprocating drive member 3.

[0037] The linear reciprocating drive member 3 is one of an oil cylinder, a cylinder or an electric push rod. In this embodiment, the linear reciprocating drive member 3 is a cylinder.

[0038] In other embodiments, the linear reciprocating drive member 3 can also be a hand-operated screw lift. Thus, the staff can move the grinding assembly 5 by manually rotating the handwheel of the hand-operated screw lift, so as to facilitate the staff to accurately control the moving position of the grinding assembly 5.

[0039] Referring to Figure 1 and Figure 2 , there are two grinding assemblies 5, and the two grinding assemblies 5 are respectively used to grind the welding slag on the first electrode wheel 121 and the second electrode wheel 122. Taking the grinding assembly 5 grinding the welding slag on the first electrode wheel 121 as an example in this embodiment, the structure and working principle of the grinding assembly 5 are explained.

[0040] Referring to Figure 1 and Figure 2 , the grinding assembly 5 includes a grinding wheel 51, a grinding wheel frame body 52, a motor 53, and a transmission belt 54. The grinding wheel frame body 52 is fixedly disposed on the mounting platform 4, the grinding wheel 51 is installed on the grinding wheel frame body 52, and the grinding wheel 51 is rotationally connected to the grinding wheel 51 frame. The motor 53 is fixedly disposed on the side of the mounting platform 4 away from the linear reciprocating drive member 3, the transmission belt 54 is sleeved on the grinding wheel 51 and the motor 53, and the motor 53 drives the grinding wheel 51 to rotate through the transmission belt 54.

[0041] The implementation principle of an automatic grinding device for a roll welding electrode wheel in an embodiment of the present application is as follows:

[0042] Referring to Figure 1 and Figure 2 , when the electrode wheel 12 roll-welds the welding strip 2, the driving end of the linear reciprocating driving member 3 drives the grinding assembly 5 to move radially towards the first electrode wheel 121, so that there is a small clearance between the grinding wheel 51 and the first electrode wheel 121; thus, when there is welding slag adhering to the first electrode wheel 121, the grinding wheel 51 can grind the welding slag on the electrode wheel 12 to remove the welding slag and other impurities on the first electrode wheel 121; thereby improving the welding quality of the two welding strips 2, reducing the damage to the first electrode wheel 121, and increasing the service life of the first electrode wheel 121.

[0043] Referring to Figure 1 and Figure 2 , the electric motor 53 drives the grinding wheel 51 to rotate through the transmission belt 54, so that the rotating grinding wheel 51 can grind the welding slag adhering to the electrode wheel 12, which can improve the cleaning effect of the grinding assembly 5 on the welding slag.

[0044] Referring to Figure 1 and Figure 2 , in addition, by installing the grinding assembly 5 on the frame 11 of the roll welding machine 1, the welding slag on the first electrode wheel 121 can be inclined in time; reducing subsequent manual grinding input, reducing labor costs and the occurrence of safety accidents.

[0045] Embodiment 2

[0046] The difference between this Embodiment 2 and Embodiment 1 is that:

[0047] Referring to Figure 3 and Figure 4 , the installation platform 4 includes a fixedly connected first mounting plate 41, an elastic member, and a second mounting plate 43, and the elastic member is fixed between the first mounting plate 41 and the second mounting plate 43; the first mounting plate 41 is fixed to the driving end of the linear reciprocating driving member 3, and the grinding assembly 5 is fixed to the second mounting plate 43.

[0048] Referring to Figure 3 , in addition, the installation platform 4 further includes a fastening bolt 44 and a fastening nut 45. Installation holes for the fastening bolt 44 to pass through are opened at the corners of the first mounting plate 41 and the second mounting plate 43, and the fastening bolt 44 is threadedly connected to the fastening nut 45 to force the first mounting plate 41 and the second mounting plate 43 to squeeze the elastic member.

[0049] Referring to Figure 3 and Figure 4, in this embodiment, the elastic member is a spring 42, and several elastic members are arranged at intervals. A plurality of limiting columns 46 are provided on one side of the first mounting plate 41 close to the second mounting plate 43. The spring 42 is sleeved on the outer periphery of the limiting column 46, and an avoidance gap is provided between the limiting column 46 and the second mounting plate 43; thereby, the position of the spring 42 is constrained by the limiting column 46 to achieve adjustable pressure, thereby improving the stability of the operation of the automatic grinding device.

[0050] Refer to Figure 3 and Figure 4 , at the same time, the first mounting plate 41 is provided with a first limiting groove 411 for accommodating the spring 42, and the second mounting plate 43 is provided with a second limiting groove 431 for accommodating the spring 42; the ends of the spring 42 are constrained by the first limiting groove 411 and the second limiting groove, so as to facilitate the staff to assemble the mounting platform 4. The mounting platform 4 further includes a first bonding member 47 and a second bonding member 48. The first bonding member 47 is used to bond the spring 42 to the first mounting plate 41, and the second bonding member 48 is used to bond the spring 42 to the second mounting plate 43. That is, the positions of both ends of the spring 42 are further fixed by the first bonding member 47 and the second bonding member 48. On the one hand, it is convenient for the staff to assemble the mounting platform 4; on the other hand, it can also improve the stability of the operation of the automatic grinding device.

[0051] In other embodiments, the elastic member can also be an airbag, a disc spring 42, a silica gel plate with holes, and other elastic structures.

[0052] The implementation principle of an automatic grinding device for a roll welding electrode wheel in an embodiment of the present application is as follows:

[0053] By providing an elastic member between the first mounting plate 41 and the second mounting plate 43, a certain flexible deformation ability is given to the mounting platform 4. Thus, when the welding slag is large and the bonding strength between the welding slag and the electrode wheel 12 is large, the flexible deformation ability of the mounting platform 4 can be utilized, so that the grinding wheel 51 can move slightly along the radial direction of the electrode wheel, and the grinding wheel 51 can apply adjustable different pressures to the welding slag, improving the grinding effect of the grinding wheel 51 on the welding slag.

[0054] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
