Description

Technical Field

[0001] This utility model relates to the technical field of steel mesh processing equipment, and in particular to a welding electrode assembly installation structure. Background Technology

[0002] When using resistance welding to weld steel mesh, linear actuators such as cylinders or hydraulic cylinders are often used to drive the two electrodes to press against each other, thereby conducting the welding circuit and causing the intersections of the steel bars to be fused together to form a steel mesh.

[0003] However, commonly used linear actuators such as cylinders often experience piston rod rotation during operation. If the electrode holder is not circular or has a nearly multi-directionally symmetrical cross-section, the welding electrode holder will rotate with the piston rod, causing a change in the electrode clamping position and preventing normal welding. Therefore, it is necessary to restrict the rotation of the electrode holder. Currently, a common method is to add a guide mounting seat with an anti-rotation rod. Existing solutions require high precision in all holes of the guide mounting seat because both the main guide rod and the anti-rotation rod are fixed. Otherwise, misalignment between the cylinder piston rod and the main guide rod may occur, and the anti-rotation rod may be unable to be installed even if the main guide rod can be installed. Increasing the fit clearance can improve assemblability, but it will also increase the clearance between components, leading to structural swaying or even impact. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a simple welding electrode assembly installation structure that is conducive to reducing the requirements for hole position accuracy and does not require increasing the fitting gap.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A welding electrode assembly mounting structure includes a telescopic drive component, a guide rod, an anti-rotation rod, a guide seat assembly, and an electrode assembly. The telescopic drive component is disposed on the guide seat assembly, and the guide rod and the anti-rotation rod pass through the guide seat assembly.

[0007] The telescopic drive component is connected to the guide rod via a spherical bearing, and / or the installation position of the telescopic drive component on the guide seat assembly is adjustable and connected to the guide rod;

[0008] The mounting position of the guide rod and / or the anti-rotation rod on the electrode assembly is adjustable.

[0009] As a further improvement to the above technical solution: the electrode assembly is provided with a positioning hole, one end of the anti-rotation rod is provided in the positioning hole and has an adjustable gap with the side wall of the positioning hole, the anti-rotation rod is provided with a slot, the electrode assembly is provided with a retaining plate, and the retaining plate is embedded in the slot.

[0010] As a further improvement to the above technical solution: the electrode assembly is provided with a first fastener that is adjustable in position, and the first fastener is connected to one end of the anti-rotation rod located in the positioning hole.

[0011] As a further improvement to the above technical solution: the anti-rotation rod is provided with a fixing plate, the fixing plate is provided with a second waist-shaped hole and is fixedly connected to the electrode assembly through a second fastener provided in the second waist-shaped hole.

[0012] As a further improvement to the above technical solution: a threaded adapter is provided between the telescopic drive and the spherical bearing, one end of the threaded adapter is threadedly connected to the telescopic drive, and the other end of the threaded adapter is threadedly connected to the spherical bearing.

[0013] As a further improvement to the above technical solution: the guide seat assembly includes a guide seat, a pad on the guide seat, and a mounting plate on the pad. The telescopic drive member is disposed on the mounting plate and passes through the pad. There is a gap between the pad and the telescopic drive member to form an operating area. The guide rod and the anti-rotation rod pass through the guide seat.

[0014] As a further improvement to the above technical solution: the pad is provided in two pieces and arranged opposite to each other on both sides of the telescopic drive member.

[0015] As a further improvement to the above technical solution: the pad is provided with a groove to form the operating area.

[0016] As a further improvement to the above technical solution: the electrode assembly includes a mounting base, an electrode seat connected to the mounting base, an insulating structure disposed between the mounting base and the electrode seat, and an electrode disposed on the electrode seat, wherein the guide rod and the anti-rotation rod are mounted on the mounting base.

[0017] As a further improvement to the above technical solution: the telescopic drive component is a pneumatic cylinder or a hydraulic cylinder.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] The welding electrode assembly installation structure disclosed in this utility model allows the telescopic drive component to reciprocate the electrode assembly via a guide rod, thereby pressing and welding the intersections of the reinforcing bars together. The guide rod and anti-rotation rod are inserted into the guide seat assembly, serving a guiding function and preventing rotation. Since the telescopic drive component is connected to the guide rod via a spherical bearing, and / or the installation position of the telescopic drive component on the guide seat is adjustable and directly connected to the guide rod, the tolerance for misalignment between the telescopic drive component and the guide rod can be increased. Because the installation position of the guide rod and / or anti-rotation rod on the electrode assembly is adjustable, during assembly, the anti-rotation rod (or guide rod) can be passed through the guide seat assembly first, and then fixed to the electrode assembly. This results in a simple structure with good assemblability, reducing the accuracy requirements of the holes on the guide seat assembly and eliminating the need for increased clearance, thus preventing shaking during use.

[0020] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] Figures 1 to 2 This illustration shows an embodiment of the welding electrode assembly mounting structure of this utility model. The welding electrode assembly mounting structure of this embodiment includes a telescopic drive component 1, a guide rod 2, an anti-rotation rod 3, a guide seat assembly 4, and an electrode assembly 5. The telescopic drive component 1 is mounted on the guide seat assembly 4. The guide rod 2 and the anti-rotation rod 3 pass through the guide seat assembly 4. The guide rod 2 is connected to the telescopic drive component 1 via a spherical bearing 61, ensuring a reliable connection and allowing for relative rotation with high flexibility. The mounting position of the anti-rotation rod 3 on the electrode assembly 5 is adjustable, while the guide rod 2 is welded to the electrode assembly 5. The telescopic drive component 1 can be a commonly used pneumatic cylinder or hydraulic cylinder, etc.

[0033] In this embodiment of the welding electrode assembly mounting structure, the telescopic drive component 1 can drive the electrode assembly 5 to reciprocate via the guide rod 2, thereby pressing and welding the intersection points of the reinforcing bars together. The guide rod 2 and the anti-rotation rod 3 are inserted into the guide seat assembly 4, which can play a guiding role and prevent rotation. Since the installation position of the anti-rotation rod 3 on the electrode assembly 5 is adjustable, during assembly, the anti-rotation rod 3 can be passed through the guide seat assembly 4 first, and then fixed to the electrode assembly 5. The structure is simple, has good assemblability, and helps to reduce the accuracy requirements of the holes on the guide seat assembly 4. It also eliminates the need to increase the fitting clearance and avoids shaking during use. Of course, in other embodiments, the installation position of the guide rod 2 on the electrode assembly 5 can also be adjustable, and the anti-rotation rod 3 can be welded to the electrode assembly 5; or the installation positions of both the guide rod 2 and the anti-rotation rod 3 on the electrode assembly 5 can be adjustable. Alternatively, the installation position of the telescopic drive component 1 on the guide seat assembly 4 is adjustable and directly connected to the guide rod 2. Adjusting the installation position of the telescopic drive component 1 can also help ensure the coaxiality between the telescopic drive component 1 and the guide rod 2. The specific adjustment method can be referred to the anti-rotation rod 3, which will not be elaborated further.

[0034] See details Figure 2 In this embodiment, the electrode assembly 5 is provided with a positioning hole 51. One end of the anti-rotation rod 3 (the lower end in this embodiment) is located in the positioning hole 51 and has an adjustable gap with the side wall of the positioning hole 51, reducing the assembly difficulty of the anti-rotation rod 3 on the electrode assembly 5. The anti-rotation rod 3 is provided with a slot 31, and the electrode assembly 5 is provided with a retaining plate 52, which is embedded in the slot 31. When the electrode assembly 5 moves back and forth, the anti-rotation rod 3 can be driven to move back and forth by the retaining plate 52 cooperating with the slot 31. Preferably, the retaining plate 52 is also installed on the electrode assembly 5 by a threaded fastener, and there is also a gap between the retaining plate 52 and the threaded fastener, which facilitates the adjustment of the installation position of the retaining plate 52, thereby adapting it to the anti-rotation rod 3.

[0035] Furthermore, in this embodiment, the electrode assembly 5 is provided with a first waist-shaped hole 53, and a first fastener 54 (such as a screw) is provided in the first waist-shaped hole 53. The first fastener 54 is connected to one end of the anti-rotation rod 3 located in the positioning hole 51, which can tighten the anti-rotation rod 3, effectively fix the anti-rotation rod 3, and facilitate disassembly.

[0036] Of course, in other embodiments, the first oblong hole 53 on the plate corresponding to the first fastener 54 can also be replaced by a round hole, but the position of the plate on the electrode assembly 5 is adjustable, and the position of the first fastener 54 can also be adjusted.

[0037] Furthermore, in this embodiment, a threaded adapter 62 is provided between the telescopic drive component 1 and the spherical bearing 61. One end of the threaded adapter 62 is threadedly connected to the telescopic drive component 1, and the other end is threadedly connected to the spherical bearing 61. By replacing the threaded adapter 62, the incompatibility problem between telescopic drive components 1 of different specifications and spherical bearings 61 can be solved, thus expanding the scope of application.

[0038] Further, in this embodiment, the guide seat assembly 4 includes a guide seat 41, a pad 42 disposed on the guide seat 41, and a mounting plate 43 disposed on the pad 42. The telescopic drive member 1 is disposed on the mounting plate 43 and passes through the pad 42. There is a gap between the pad 42 and the telescopic drive member 1 to form an operating area 44. The guide rod 2 and the anti-rotation rod 3 pass through the guide seat 41. The operating area 44 allows observation of whether the locking nut of the cylinder or hydraulic cylinder has become loose, and the piston rod can be rotated and fixed without disassembling the cylinder or hydraulic cylinder. The structure is simple and easy to use. Preferably, the pad 42 is a split structure, distributed on both sides of the telescopic drive member 1 to form the operating area 44. The structure is simple and easy to process. Of course, in other embodiments, the pad 42 can also be an integral structure with grooves to form the operating area 44.

[0039] Furthermore, in this embodiment, the electrode assembly 5 includes a mounting base 55, an electrode seat 56 connected to the mounting base 55 (e.g., by screws, bolts, etc.), an insulating structure 57 disposed between the mounting base 55 and the electrode seat 56, and an electrode 58 disposed on the electrode seat 56. The guide rod 2 and the anti-rotation rod 3 are mounted on the mounting base 55.

[0042] In this embodiment, the anti-rotation rod 3 is provided with a fixing plate 32, the fixing plate 32 is provided with a second waist-shaped hole 33 and is fixedly connected to the electrode assembly 5 through a second fastener 34 (such as a screw) provided in the second waist-shaped hole 33.

[0043] During assembly, the anti-rotation rod 3 can be passed through the guide seat assembly 4 first, and then the position of the second fastener 34 in the second waist-shaped hole 33 can be adjusted to align with the threaded hole on the mounting seat 55. Finally, the second fastener 34 is tightened to fix the anti-rotation rod 3 on the mounting seat 55. The structure is simple and has good assemblability, which helps to reduce the hole position accuracy requirements on the guide seat assembly 4 and does not require increasing the fitting clearance, thus avoiding shaking during use.

[0044] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
