Description

Technical Field

[0001] The utility model relates to the field of electrode cap disassembly mechanisms, in particular to an electrode cap disassembly mechanism. Background Art

[0002] The electrode cap is a type of welding electrode used for resistance welding equipment, such as fixed spot welders, hanging spot welders, and manipulator spot welders. Because it is placed on the electrode connecting rod, it is called an electrode cap. After a certain number of welding, it needs to be repaired or replaced due to wear and tear, and is a welding consumable part. In the welding of automotive sheet metal, after the welding machine or welding clamp has been working for a period of time, the surface of the electrode cap at the end will be oxidized or will be sticky with impurities, affecting the quality of the weld. Therefore, the electrode cap must be replaced regularly.

[0003] Existing electrode cap replacement equipment, such as the electrode cap grinding and replacement machine disclosed in Patent No. CN220612617U, fixes the electrode cap by removing the teeth in the riser, and removes the electrode cap on the electrode connecting rod by transmitting torque, which can save a lot of labor expenses. When used in conjunction with a welding robot, it can realize full automation of welding and improve production efficiency.

[0004] However, due to the design of the riser teeth for removing the electrode cap, the replacement equipment needs to be equipped with two cap removal ports for forward rotation cap removal and reverse rotation cap removal respectively. Such a design not only increases the size of the replacement equipment, but also increases the step of the robot moving the motor connecting rod when used in conjunction with a robot, which places high requirements on the positioning of the robot and easily reduces production efficiency. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an electrode cap disassembly mechanism, which reduces the number of configurations of the cap disassembly openings, reduces the size of the disassembly mechanism, and improves the disassembly efficiency of the electrode cap.

[0006] The technical solution of the utility model is achieved in this way:

[0007] An electrode cap removal mechanism comprises: a cap removal platform driven gear, a transmission assembly driven gear and a driving cylinder driven gear, the cap removal platform driven gear comprises a cap removal port driven gear, a columnar caliper driven gear arranged on the inner wall of the cap removal port driven gear, and an avoidance portion driven gear for providing an accommodation space for the columnar caliper driven gear, the transmission assembly driven gear is transmission-connected to the cap removal platform driven gear, and the driving cylinder driven gear drives the cap removal port driven gear to rotate via the transmission assembly driven gear.

[0008] As a preferred embodiment, the cap removal station driven gear includes a fixed part driven gear, a driven gear and a rotating part driven gear, the fixed part driven gear abuts against the transmission assembly driven gear, and the rotating part driven gear is installed on the fixed part driven gear.

[0009] As a preferred embodiment, the cap removal driven gear is arranged on the rotating part driven gear, and the outer surface of the rotating part driven gear is sleeved with a driven gear.

[0010] As a preferred embodiment, a transmission gear, driven gear and driven gear are arranged inside the fixed part driven gear, and the transmission gear, driven gear and driven gear are meshed with the driven gear, driven gear and driven gear to drive the unloading port driven gear and driven gear to rotate.

[0011] As a preferred embodiment, the transmission assembly driven gear includes a transmission connecting rod driven gear and a transmission cavity driven gear that accommodates the transmission connecting rod driven gear, and the transmission connecting rod driven gear is provided with a plurality of latching teeth driven gear.

[0012] As a preferred embodiment, one end of the transmission connecting rod driven gear is transmission connected to the driving cylinder driven gear, and one end of the fixed part driven gear extends into the transmission cavity driven gear for fixation.

[0013] As a preferred implementation manner, one side of the transmission connecting rod driven gear driven gear provided with the latching gear driven gear driven gear meshes with the transmission gear driven gear driven gear driven gear in the fixed part driven gear driven gear driven gear.

[0014] As a preferred embodiment, the fixed part driven gear driven gear driven gear includes an upper cover plate driven gear driven gear driven gear and a lower cover plate driven gear driven gear driven gear, and the upper cover plate driven gear driven gear driven gear and the lower cover plate driven gear driven gear driven gear are covered to form a cavity for accommodating the driven gear driven gear driven gear and the transmission gear driven gear driven gear driven gear.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] (1) The utility model provides an electrode cap removal mechanism that replaces the traditional one-way rotating teeth by improving the caliper structure of the cap removal opening. The traditional cap removal opening can only perform one-way rotating cap removal due to its tooth structure. When the caps need to be removed at both ends of the electrode connecting rod, at least two cap removal openings need to be configured, which increases the production cost and increases the size of the equipment. One round of cap removal work needs to be completed at the two cap removal openings, which also increases the labor cost. When the cap removal work is performed in conjunction with a robot, the two cap removal openings need to be positioned and the rotation direction set, resulting in a decrease in work efficiency. The present application fixes the electrode cap by a columnar caliper, and can complete the cap removal operation of rotating in any direction without adding a cap removal opening or increasing the operation steps. It can reduce the size of the equipment while improving work efficiency. It can also reduce the complexity of the operation when working in conjunction with a robot.

[0017] (2) The utility model uses an electrode cap removal mechanism that drives an air cylinder to replace the traditional motor drive. Due to the inertia of the motor, the traditional motor drive still takes a while to stop after rotation, and the cap removal operation does not require multiple rounds of rotation to complete. Compared with the motor drive, the air cylinder drive controls the number of rotations through the stroke of the transmission connecting rod, thereby accurately completing the cap removal work and reducing power consumption and machine wear. At the same time, the cylinder start-up instead of the motor drive can avoid the risk of electric shock, and has high practicality and safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", "fourth", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] See also Figures 1 to 5 The utility model discloses an electrode cap disassembly mechanism, including a cap removal platform 1, a transmission assembly 2 and a driving cylinder 3. The cap removal platform 1 includes a cap removal opening 11, a columnar caliper 12 arranged on the inner wall of the cap removal opening 11 and an avoidance portion 13 for providing an accommodation space for the columnar caliper 12. The transmission assembly 2 is connected to the cap removal platform 1 in a transmission manner, and the driving cylinder 3 drives the cap removal opening 11 to rotate through the transmission assembly 2.

[0029] Specifically, compared with the traditional toothed caliper, the cylindrical caliper 12 has an arc-shaped surface, which can not only clamp the electrode cap inserted into the cap removal port 11, but also complete the rotational cap removal operation in any direction. Compared with the traditional toothed caliper structure, the number of cap removal ports 11 can be reduced when completing the same cap removal work, and completing the cap removal operation at the same cap removal port 11 is compared to first rotating the cap through the first cap removal port 11 forwardly and then rotating the cap through the second cap removal port reversely, which can improve the work efficiency of cap removal and reduce the volume of the electrode cap disassembly mechanism.

[0030] Furthermore, an avoidance portion 13 is provided next to the columnar caliper 12. When the columnar caliper 12 is needed to engage the inserted electrode cap, the columnar caliper 12 slides out from the avoidance portion 13 to fix the electrode cap. When not in operation, in order to avoid damage to personnel and equipment caused by accidental touch, the columnar caliper 12 is retracted into the avoidance portion 13 until it is needed to work and then extended to fix the electrode cap.

[0031] As a preferred embodiment, the cap removal platform 1 includes a fixed portion 101 and a rotating portion 102 , the fixed portion 101 abuts against the transmission assembly 2 , and the rotating portion 102 is installed on the fixed portion 101 .

[0032] As a preferred embodiment, the cap removal port 11 is provided on the rotating part 102 , and a driven gear 14 is sleeved on the outer surface of the rotating part 103 .

[0033] As a preferred embodiment, a transmission gear 15 is disposed in the fixing portion 101 , and the transmission gear 15 engages with the driven gear 14 to drive the cap removal opening 11 to rotate.

[0034] As a preferred embodiment, the transmission assembly 2 includes a transmission connecting rod 21 and a transmission cavity 22 for accommodating the transmission connecting rod 21 , and a plurality of latching teeth 23 are provided on the transmission connecting rod 21 .

[0035] Specifically, the transmission connecting rod 21 can be used to notify the stroke of the transmission connecting rod 21 through the cylinder, so as to accurately control the number of rotations of the cap removal port 11, which can save the production drive cost and reduce the waste of drive cost.

[0036] Furthermore, the use of a driving cylinder 3 instead of a traditional motor drive can avoid the risk of electric shock in the cap removal mechanism. In addition to the risk to personnel, the presence of a conductive medium in the working environment that touches the motor, i.e., the structure connected to the motor, will easily cause the risk of electric shock. Therefore, the implementation method of the driving cylinder 3 can not only provide a precise power source for the electrode cap removal operation, but also ensure production safety.

[0037] As a preferred implementation, one end of the transmission connecting rod 21 is transmission-connected to the driving cylinder 3 , and one end of the fixing portion 101 extends into the transmission cavity 22 for fixing.

[0038] As a preferred implementation, the side of the transmission connecting rod 21 provided with the latching teeth 23 meshes with the transmission gear 15 in the fixing portion 101 .

[0039] As a preferred implementation, the fixing portion 101 includes an upper cover plate 103 and a lower cover plate 104 , and the upper cover plate 103 and the lower cover plate 104 are overlapped to form a cavity for accommodating the driven gear 14 and the transmission gear 15 .

[0040] The utility model discloses an electrode cap disassembly mechanism. The utility model discloses an electrode cap disassembly mechanism. The electrode cap disassembly mechanism replaces the traditional one-way rotating teeth by improving the caliper structure of the cap removal opening. The traditional cap removal opening can only perform one-way rotating cap removal due to the structure of the teeth. When the caps need to be removed at both ends of the electrode connecting rod, at least two cap removal openings need to be configured, which increases the production cost and makes the equipment larger. One round of cap removal work needs to be completed at the two cap removal openings, which also increases the labor cost. When the robot is used to perform the cap removal work, the two cap removal openings need to be positioned and the rotation direction set, resulting in reduced work efficiency. The present application fixes the electrode cap by a columnar caliper, and can complete the rotational cap removal operation in any direction without adding a cap removal opening and increasing the operation steps. The equipment can be reduced in size while improving work efficiency. The complexity of the operation can also be reduced when the robot is used.

[0041] The utility model discloses an electrode cap removal mechanism that replaces the traditional motor drive mode with a driving cylinder. The traditional motor drive still needs a period of time to stop after rotation due to the inertia of the motor, and the cap removal operation can be completed without multiple rounds of rotation. Compared with the motor drive, the cylinder drive controls the number of rotations through the stroke of the transmission connecting rod, thereby accurately completing the cap removal work and reducing power consumption and machine wear. At the same time, the cylinder start-up instead of the motor drive can avoid the risk of electric shock, and has high practicality and safety.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
