Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to an electrode cap grinding machine. Background Technology

[0002] Resistance welding technology is widely used in various metal joining fields. Among them, the electrode cap is a key component of the welding equipment, and the condition of its end face directly affects the welding quality and stability. Electrode caps are usually made of conductive and wear-resistant materials such as chromium zirconium copper. However, during the welding process, due to repeated exposure to high temperature, high pressure and strong current, its end face will inevitably wear, deform or oxidize, resulting in increased contact resistance and reduced weld quality.

[0003] Generally, after welding about 30-50 weld points, the end face of the electrode cap begins to deteriorate, requiring re-grinding to restore its original shape and finish. Current methods mainly rely on automated electrode cap re-grinding devices, such as removing the wear layer through milling.

[0004] However, the unique installation position of the electrode cap in welding equipment such as "double-head single-sided welding machines" makes it difficult to directly apply existing general-purpose automatic electrode cap grinding devices. Therefore, developing a device capable of performing grinding operations specifically for the electrode caps of double-head single-sided welding machines to improve production efficiency is a pressing technical problem in this field.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0034] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0035] like Figures 1-6As shown in the figure, an electrode cap grinding machine provided by this utility model includes a grinding head 10, a drive source, a first grinding tool 12 and a second grinding tool 13 connected to the drive source respectively, the drive source being adapted to drive the first grinding tool 12 and the second grinding tool 13 to rotate, so as to grind the corresponding electrode cap of the double-headed single-sided welding machine; a lifting assembly 20 connected to the grinding head 10, the lifting assembly 20 being used to drive the grinding head 10 to move relative to the electrode cap along a predetermined trajectory; and a control assembly 30 electrically connected to the drive source and the lifting assembly 20 respectively, the control assembly 30 being used to control the drive source and the lifting assembly 20 respectively.

[0036] In this embodiment, the grinding head 10 is the core component for performing electrode cap grinding operations. The grinding head 10 contains a drive source. The drive source can be a motor 11, a pneumatic motor, or other device capable of providing rotational power. The drive source is connected to the first grinding tool 12 and the second grinding tool 13 via a suitable transmission connection.

[0037] These two regrinding tools are components that directly contact and cut the electrode caps. The function of the drive source is to drive the first regrinding tool 12 and the second regrinding tool 13 to rotate synchronously. Through the rotation of the regrinding tools, effective cutting and regrinding operations can be performed on the two corresponding electrode caps on the double-head single-sided welding machine. For example, when the two electrode caps of the double-head single-sided welding machine need regrinding, the two regrinding tools can be aligned with the two electrode caps respectively.

[0038] The lifting assembly 20 is securely connected to the grinding head 10, allowing the grinding head 10 to move along with the lifting assembly 20 as a load. The lifting assembly 20 drives the grinding head 10 to move along a predetermined trajectory relative to the electrode cap to be ground. This "movement along a predetermined trajectory" includes at least: before grinding begins, moving the grinding head 10 from an initial or standby position to a working position near the electrode cap, so that the first grinding tool 12 and the second grinding tool 13 can effectively contact the corresponding electrode cap or maintain an appropriate grinding distance; during grinding, it may also include fine-tuning feed movements; and after grinding is completed, removing the grinding head 10 from the working position and returning it to the initial or standby position. This movement along the predetermined trajectory can be a vertical lifting motion.

[0039] The control component 30 is electrically connected to both the drive source and the lifting component 20. The core function of the control component 30 is to control the drive source and the lifting component 20 according to preset program logic, sensor signals, or other external commands. Specifically, the control component 30 can control the start and stop of the drive source, thereby controlling the rotational state of the first regrinding tool 12 and the second regrinding tool 13. Simultaneously, the control component 30 can control the lifting component 20 to execute specific motion sequences, such as driving the regrinding head 10 to rise to the regrinding position, staying at the regrinding position for a predetermined time, and then driving the regrinding head 10 to descend and reset. Through the coordinated control of the drive source and the lifting component 20, this regrinding machine can automatically complete the regrinding cycle of the two electrode caps of a double-headed single-sided welding machine.

[0040] With the above structure, the electrode cap grinding machine provided in this embodiment uses a grinding head 10 containing a first grinding tool 12 and a second grinding tool 13 to adapt to the structure of a double-head welding machine. The lifting assembly 20 drives the grinding head 10 to move along a predetermined trajectory to perform the grinding action, thereby effectively solving the problem in the background art that general-purpose grinding machines are difficult to grind the electrode caps of double-head single-sided welding machines.

[0041] In one embodiment, the drive source includes a motor 11 and a gear transmission mechanism, wherein the motor 11 is connected to the first shaving tool 12 and the second shaving tool 13 respectively through the gear transmission mechanism.

[0042] In this embodiment, the driving source specifically includes a motor 11 and a gear transmission mechanism.

[0043] The motor 11 serves as the power source for the rotation of the grinding tools in the entire grinding head 10, and the output shaft of the motor 11 provides the initial rotational power.

[0044] A gear transmission mechanism is positioned between the motor 11 and the first regrinding tool 12 and the second regrinding tool 13. Its function is to stably and reliably transmit the rotational motion and power of the motor 11 to these two regrinding tools. Specifically, the output shaft of the motor 11 is connected to the input portion of the gear transmission mechanism, while the output portion of the gear transmission mechanism is connected to the first regrinding tool 12 and the second regrinding tool 13, respectively, thereby driving their rotation. Through the gear transmission mechanism, torque transmission can be achieved, ensuring the movement of the first regrinding tool 12 and the second regrinding tool 13.

[0045] The combination of motor 11 and gear transmission mechanism is used as the drive source, which has a relatively simple and compact structure, high transmission efficiency, and can provide sufficient grinding torque. When the control component 30 controls the motor 11 to start, the power generated by the motor 11 is transmitted to the first grinding tool 12 and the second grinding tool 13 through the gear transmission mechanism, causing them to rotate and perform grinding operations on the electrode cap.

[0046] In one embodiment, the gear transmission mechanism includes a motor gear 111 connected to the output shaft of the motor 11, a linkage gear 112 coaxially arranged with the motor gear 111, and a driven gear 113 meshing with the linkage gear 112. The driven gear 113 is meshed with the first grinding tool 12 and the second grinding tool 13 respectively.

[0047] In this embodiment, the gear transmission mechanism specifically includes a motor gear 111, a linkage gear 112, and a driven gear 113.

[0048] The motor gear 111 is directly connected to the output shaft of the motor 11, or fixedly connected to the output shaft of the motor 11 via a coupling or other means. When the motor 11 rotates, the motor gear 111 rotates accordingly, serving as the power input end of the entire gear transmission mechanism. The linkage gear 112 is coaxially and fixedly connected to the motor gear 111, and rotates together with the motor gear 111. This means that the linkage gear 112 rotates together with the motor gear 111, and its function is to transmit power to the subsequent driven gear 113.

[0049] Driven gear 113 meshes with driven gear 112. When motor 11 drives motor gear 111 and its coaxial driven gear 112 to rotate, driven gear 112 subsequently drives driven gear 113 to rotate. Driven gear 113 is configured to mesh with first shaving tool 12 and second shaving tool 13 respectively. This means that after receiving power from driven gear 112, driven gear 113 distributes and transmits this power to first shaving tool 12 and second shaving tool 13, enabling them to rotate simultaneously for shaving operations. For example, driven gear 113 can mesh directly with different sectors of its circumference or through different portions of its tooth profile, simultaneously with the teeth of first shaving tool 12 and second shaving tool 13. In this way, one driven gear 113 can effectively drive two shaving tools to rotate synchronously. This transmission design is compact and reliably transmits power from driven gear 112 to the two shaving tools.

[0050] This gear transmission mechanism, through the combination of motor gear 111, linkage gear 112 and driven gear 113, can effectively distribute and transmit the power of motor 11 to the first grinding tool 12 and the second grinding tool 13, thereby realizing the grinding of two electrode caps at the same time.

[0051] In one embodiment, the first grinding tool 12 and the second grinding tool 13 are both grinding gears. The grinding gear includes a gear body 121 and a grinding part 122 disposed on the gear body 121. The gear body 121 is meshed with the driven gear 113.

[0052] In this embodiment, both the first regrinding tool 12 and the second regrinding tool 13 are regrinding gears. Specifically, each regrinding gear includes a gear body 121 and a regrinding portion 122 disposed on the gear body 121.

[0053] The outer circumferential surface of the gear body 121 has teeth (tooth portion) for meshing with the driven gear 113 in the aforementioned gear transmission mechanism. Through this meshing connection, the power generated when the driven gear 113 rotates can be effectively transmitted to the grinding gear and drive the grinding gear to rotate.

[0054] The grinding section 122 is the part of the grinding gear that actually performs the grinding of the electrode cap. This grinding section 122 is located inside the gear body 121. The gear body 121 has a ring-shaped structure, and its inner surface or inner edge forms a grinding structure with cutting edges, grinding surfaces, or specific profiles. When the grinding gear rotates, the electrode cap is located inside the grinding gear, contacts the inner grinding section 122, and generates relative movement, thereby removing the wear layer, oxides, or deposits from the surface of the electrode cap, restoring the geometry and surface finish of the electrode cap.

[0055] The first regrinding tool 12 and the second regrinding tool 13 are designed as a regrinding gear structure comprising a gear body 121 and a regrinding section 122, primarily to achieve a reliable transmission connection with the driven gear 113 using the gear body 121. This integrated design allows for a more compact structure and more direct transmission.

[0056] In one embodiment, the grinding head 10 further includes a gearbox, a gear transmission mechanism is disposed inside the gearbox, and a through hole 141 is provided through the top of the gearbox downwards. The number and position of the through holes 141 match the first grinding tool 12 and the second grinding tool 13.

[0057] In this embodiment, the grinding head 10 also includes a gearbox. The gear transmission mechanism, namely the combination of motor gear 111, driving gear 112, and driven gear 113 described in the foregoing embodiments, is integrally disposed inside the gearbox. The gearbox provides a semi-enclosed housing space for these gears, which can protect the gears. The gearbox consists of an upper cover 142 and a lower cover 143 or other housing structure, which encloses the gear transmission mechanism.

[0058] To enable the first regrinding tool 12 and the second regrinding tool 13 to contact the external electrode cap for regrinding, a through hole 141 is provided downward through the top of the gearbox (e.g., the top cover 142). Here, "top" is relative and can also be understood as the side of the gearbox facing the regrinding direction of the regrinding tool. The number and position of the through holes 141 match the first regrinding tool 12 and the second regrinding tool 13. This means that the through holes 141 on the gearbox correspond precisely to the mounting positions of the first regrinding tool 12 and the second regrinding tool 13, allowing the regrinding portions 122 of these two regrinding tools to be exposed through the through holes 141, thereby contacting the electrode cap to be regrinded. This design protects the internal transmission mechanism while ensuring the normal operation of the regrinding tools.

[0059] In one embodiment, the center distance between the first regrinding tool 12 and the second regrinding tool 13 is configured to match the center distance between the two electrode caps of the double-headed single-sided welding machine.

[0060] In this embodiment, one of the core features of the dual-head single-sided welding machine is that it has two independent welding heads, each with an electrode cap. These two electrode caps act on the workpiece simultaneously during welding. The two electrode caps are fixedly mounted on the welding machine, and the center distance between them is a predetermined design parameter.

[0061] To enable simultaneous grinding of both electrode caps, this embodiment sets the center distance (i.e., the straight-line distance between the rotation centers of the two tools) of the first grinding tool 12 and the second grinding tool 13 to be the same as the center distance between the two electrode caps of the double-headed single-sided welding machine. This achieves the following effect: when the grinding head 10 moves to the working position via the lifting assembly 20, the first grinding tool 12 can accurately align with the first electrode cap, and the second grinding tool 13 can accurately align with the second electrode cap. Thus, once the drive source is activated, the two grinding tools can simultaneously grind their respective electrode caps without requiring additional translational adjustments to the grinding head 10 to align with the two electrode caps, thereby greatly improving grinding efficiency, simplifying the operation process, and ensuring the accuracy of the grinding position.

[0062] In one embodiment, a copper shavings collector 40 is also included. The copper shavings collector 40 includes a negative pressure device 41 disposed on one side of the grinding head 10, a collection bucket 42 communicating with the negative pressure device 41, and an air blowing module 43 disposed on the grinding head 10. The air blowing module 43 is used to blow the copper shavings generated during grinding toward the negative pressure device 41.

[0063] In this embodiment, the negative pressure device 41 is located near the grinding head 10. The function of the negative pressure device 41 is to generate suction to remove copper shavings generated during the grinding process. It can be a small fan, a vacuum generator, or other device capable of generating negative pressure airflow. Its installation near the grinding head 10 allows its suction port to be close to the source of copper shavings, namely the working areas of the first grinding tool 12 and the second grinding tool 13.

[0064] The collection bin 42 is connected to the negative pressure device 41 via a pipe. The suction generated by the negative pressure device 41 draws copper shavings through the pipe and collects them into the collection bin 42. The collection bin 42 is a container for temporarily storing the collected copper shavings and can be cleaned or replaced periodically. For easy installation and fixation, the collection bin 42 can be connected to other components of the overall structure of the grinding machine, such as the column 50.

[0065] The air blowing module 43 is mounted on the grinding head 10, located near the first grinding tool 12 and the second grinding tool 13, and its air blowing direction is directed towards the suction port of the negative pressure device 41. The function of the air blowing module 43 is to disperse copper shavings adhering to the electrode cap, grinding tools, or the surface near the grinding head 10 by spraying air during or after grinding, making them easier for the negative pressure device 41 to suck away, thereby improving the collection efficiency of copper shavings. The air source for the air blowing module 43 can be provided by an external compressed air device.

[0066] Through the active blowing of the air module 43 and the continuous suction of the negative pressure device 41, combined with the collection of the storage bucket 42, the copper shavings collector 40 in this embodiment can effectively remove and collect the copper shavings generated during the grinding process, keep the working area clean, and reduce the negative impact of copper shavings on the grinding machine and the environment.

[0067] In one embodiment, the system also includes a column 50, a lifting assembly 20 disposed on the column 50, the lifting assembly 20 including a cylinder 21 and a guide rail slider mechanism 22 connected to the cylinder 21, the guide rail slider mechanism 22 being connected to the grinding head 10.

[0068] In this embodiment, the grinding machine also includes a column 50. The column 50 serves as the main support structure of the grinding machine, comprising a horizontally positioned base and a support column vertically mounted on the base, providing a stable mounting reference for other moving parts. A lifting assembly 20 is integrally fixedly mounted on the column 50. The lifting assembly 20 includes a cylinder 21 and a guide rail slider mechanism 22 connected to the cylinder 21.

[0069] Cylinder 21 is the power source for the lifting assembly 20 and can be a pneumatic cylinder 21. One end of cylinder 21 is fixed to the fixed frame of the lifting assembly 20, and the other end is used to drive the lifting and lowering of the grinding head 10. By controlling the air passage to cylinder 21 through the control assembly 30, the piston rod of cylinder 21 can be extended or retracted, thereby providing the thrust or pull force required for the lifting and lowering movement.

[0070] The guide rail slider mechanism 22 is used to guide and support the vertical movement of the grinding head 10. The guide rail slider mechanism 22 includes a fixed part and a sliding part. The fixed part is fixedly connected to the column 50, and the sliding part is fixedly connected to the grinding head 10. The cylinder 21 is connected to the sliding part to drive it to perform lifting and lowering movements.

[0071] By employing a combination of column 50, cylinder 21, and guide rail slider mechanism 22, the vertical position of the grinding head 10 can be controlled to adapt to the grinding needs of electrode caps of different heights.

[0072] In one embodiment, the guide rail slider mechanism 22 includes a mounting plate 221, which is fixedly connected to the column 50. At least two parallel guide rails 222 are provided on one side of the mounting plate 221. The at least two guide rails 222 are slidably engaged with sliders 223, and the sliders 223 are connected to a connecting plate 224. The piston rods of the grinding head 10 and the cylinder 21 are fixedly connected to the connecting plate 224.

[0073] In this embodiment, the guide rail slider mechanism 22 includes a mounting plate 221 fixedly connected to the column 50, and two parallel, vertical guide rails 222 fixed to one side of the mounting plate 221. Each guide rail 222 has two sliders 223 slidably engaged. Here, the guide rail 222 is the aforementioned fixed part, and the slider 223 is the aforementioned sliding part.

[0074] The guide rail 222 is parallel to the column 50, and the slider 223 can slide linearly along the guide rail 222. The sliders 223 on the two guide rails 222 are connected to a connecting plate 224, which forms a stable moving platform on which the grinding head 10 is fixedly mounted.

[0075] The piston rod of cylinder 21 is connected to connecting plate 224. When cylinder 21 is activated, the thrust or pull it generates acts directly on connecting plate 224, thereby driving slider 223 and grinding head 10 fixed thereon to move synchronously up and down along two parallel guide rails 222. In this way, grinding head 10 can reach the preset grinding position or standby position.

[0076] In one embodiment, the control component 30 includes a lifting solenoid valve 31, a chip blowing solenoid valve 32, and a proximity switch 33; wherein, the lifting solenoid valve 31 is connected to the cylinder 21, the chip blowing solenoid valve 32 is connected to the air blowing module 43, and the proximity switch 33 is disposed on the mounting plate 221 for detecting the position of the grinding head 10 on a predetermined trajectory.

[0077] In this embodiment, the control component 30 specifically includes the following components:

[0078] Lifting solenoid valve 31: This solenoid valve is connected to the air passage of cylinder 21 in the lifting assembly 20 described in the previous embodiment. The control assembly 30 controls the energization and de-energization of the lifting solenoid valve 31 to switch the air intake and exhaust directions of cylinder 21, thereby controlling the extension and retraction of the piston rod of cylinder 21. This in turn drives the connecting plate 224 connected to cylinder 21 and the grinding head 10 fixed thereon to rise and fall to reach the grinding position or the standby position.

[0079] Slag blowing solenoid valve 32: This solenoid valve is connected to the air supply line of the air blowing module 43 in the copper slag collector described in the previous embodiment. The control component 30 controls the supply and cutoff of compressed air to the air blowing module 43 by controlling the energization and de-energization of the slag blowing solenoid valve 32. At a specific stage of the grinding process or after grinding is completed, the control component 30 drives the slag blowing solenoid valve 32 to open, causing the air blowing module 43 to spray airflow to sweep away copper slag from the electrode cap and surrounding area, assisting the negative pressure device 41 in collection.

[0080] Proximity switch 33: Proximity switch 33 is a sensor used to detect the position of an object. In this embodiment, a mounting plate 221 can be set on top to detect the upper limit of the grinding head 10. When the grinding head 10 moves upward to the predetermined position, the proximity switch 33 is triggered. After receiving the signal, the control component 30 can stop the action of the cylinder 21 or perform the next operation.

[0081] The control component 30 receives signals from sensors such as the proximity switch 33 according to the preset program logic, and controls the operation of the lifting solenoid valve 31 and the chip blowing solenoid valve 32 accordingly, thereby realizing the operation of the grinding machine.

[0082] In one embodiment, an electrical control cabinet 60 is also provided on the column 50. The electrical control cabinet 60 includes a contactor 61, an air switch 62, and a terminal block 63.

[0083] In this embodiment, the grinding machine also includes an electrical control cabinet 60. The electrical control cabinet 60 is the central hub of the entire grinding machine's electrical system, used to house, protect, and organize various electrical control components.

[0084] The electrical control cabinet 60 contains, but is not limited to, the following electrical components:

[0085] Contactor 61: This contactor 61 is electrically connected to the main circuit of the drive source. The control component 30 controls the coil of the contactor 61 to be energized or de-energized through its output signal, thereby controlling the closing and opening of the main contacts of the contactor 61, and thus realizing the start and stop control of the drive source.

[0086] Air switch 62 is installed at the power input terminal or on the main branch circuit of electrical control cabinet 60. Its main function is to act as a control switch for the main power supply of the grinding machine or important circuits, used to manually connect or disconnect the power supply.

[0087] It provides overload and short-circuit protection. When an overload or short-circuit fault occurs in the circuit, the air switch 62 can automatically trip, cut off the power supply, and protect the drive source, control components 30 and other electrical equipment from damage.

[0088] Terminal block 63: Terminal block 63 is used for wire connections within the electrical control cabinet 60 and between the electrical control cabinet 60 and external equipment, such as motor 11, solenoid valves, sensors, etc. All wires entering and exiting the electrical control cabinet 60, as well as the connection wires between various components within the cabinet, can be transferred and distributed through terminal block 63.

[0089] These electrical components, together with the control assembly 30 and drive source described in the foregoing embodiments, constitute the electrical control system of the grinding machine. The electrical control cabinet 60 may also include other necessary electrical components such as switching power supplies, relays, indicator lights, and buttons.

[0090] In one embodiment, the control component 30 is configured to, upon receiving a grinding instruction from the dual-head single-sided welding machine, control the lifting component 20 to move the grinding head 10 to the grinding position of the electrode cap, then control the drive source to drive the first grinding tool 12 and the second grinding tool 13 to rotate for cutting and grinding, and after the grinding is completed, control the drive source to stop and control the lifting component 20 to move the grinding head 10 back to its original position.

[0091] In this embodiment, the control component 30 is configured to execute the following automated grinding sequence:

[0092] Receive grinding command: This grinding command can be sent by the operator to the control component 30 via a button.

[0093] Moving to the grinding position: Once the control component 30 receives a valid grinding command, it will first activate the lifting component 20. The lifting component 20 drives the grinding head 10 to move upward from its standby position until it reaches the grinding position of the electrode cap. This grinding position is pre-set and calibrated to ensure that the first grinding tool 12 and the second grinding tool 13 can accurately align with and effectively contact the two electrode caps. Reaching this position can be confirmed by time control, encoder feedback, or detection by the proximity switch 33.

[0094] Execution of cutting and grinding: Once the control component 30 confirms that the grinding head 10 has reached the grinding position, it will control the drive source to start working. The drive source drives the first grinding tool 12 and the second grinding tool 13 to rotate synchronously through a gear transmission mechanism. The rotating grinding tools contact the surface of the electrode cap, perform cutting, remove the wear and oxide layer on the surface of the electrode cap, and restore its original geometry and working performance.

[0095] During this process, the control component 30 can simultaneously or intermittently activate the air blowing module 43 and the negative pressure device 41 to remove and collect the copper shavings generated during grinding.

[0096] Stop grinding and reset: When the preset grinding time is reached, the control component 30 first controls the drive source to stop working. Then, the control component 30 controls the lifting component 20 again to move the grinding head 10 back to its initial standby position. This reset action is also achieved by controlling the lifting solenoid valve 31.

[0097] With the above configuration, the control component 30 realizes automated control of the entire electrode cap grinding process. From receiving instructions, positioning, grinding, chip removal to resetting, no manual intervention is required, which improves production efficiency and the stability of grinding quality.

[0098] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
