Description

Technical Field

[0001] This utility model relates to the technical field of quick-change equipment for welding wire reels, and specifically to a quick-disassembly and assembly structure for welding wire reels. Background Technology

[0002] Electric welding machines are widely used in the manufacturing industry. Different products produced in the manufacturing industry require different parts, and these parts need to be connected using electric welding machines. Electric welding machines can effectively connect metal parts together, making them more stable and durable, thereby improving the quality and life of the products. The surface of the electric welding machine has a welding wire spool.

[0003] Chinese patent application CN202220107087.2 discloses a novel welding wire spool, belonging to the field of welding wire spool technology. Its key technical features include a rotating shaft, an installation assembly, a disassembly assembly, and a wire guide assembly. A sliding rod is connected to the end of the rotating shaft, and baffles are slidably connected to the sliding rod. During installation of the welding wire spool, two sets of baffles pass through the sliding rod. As the baffles slide on the sliding rod, they compress the installation assembly. When the baffles contact the end of the rotating shaft, the installation assembly resets, allowing the installation assembly and the rotating shaft to limit and fix the baffles on both sides, thus enabling the assembly of the welding wire spool. The operation is simple and convenient. The welding wire spool is a core component for storing and feeding welding wire in welding operations. Its assembly and disassembly efficiency directly affects the cycle time of the welding production line and the convenience of maintenance. Currently, the traditional assembly and disassembly method used in the industry mainly relies on manual alignment of the positioning holes with the positioning shaft of the wire feeding mechanism. Due to the different specifications or batches of welding wire spools, the angle and number of positioning holes relative to the shaft holes may vary. During traditional assembly and disassembly, the operator needs to repeatedly rotate the welding wire spool to find the position of the positioning holes, which has the following problems: difficulty in orienting the positioning holes and time-consuming assembly and disassembly. Especially in batch operations, the average time for a single assembly and disassembly increases significantly, seriously reducing production efficiency. Utility Model Content

[0004] In view of this, the present invention provides a quick disassembly and assembly structure for welding wire reels. By designing a quick disassembly and assembly structure, the welding wire reel can be quickly disassembled and efficiently installed. This solves the problem that welding wire reels of different specifications or batches may have differences in the angle and number of positioning holes relative to the shaft holes. In traditional disassembly and assembly, the operator needs to repeatedly rotate the welding wire reel to find the position of the positioning holes, which results in difficulties in orienting the positioning holes and long disassembly and assembly time. Especially in batch operations, the average time for a single disassembly and assembly is greatly increased, which seriously reduces production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a quick-release and disassembly structure for welding wire spools, including an indicator disc. The outer wall of the indicator disc has numerical scale markings. A through hole matching the shaft hole of the welding wire spool is formed on the axis of the indicator disc. A rotating groove is formed inside the top side wall of the indicator disc, and a rotating frame is arranged inside the groove. A turntable is arranged at the lower part of the rotating frame, and a positioning pin matching the positioning hole of the welding wire spool is arranged at the lower part of the turntable. A positioning frame coinciding with the axis of the positioning pin is arranged at the upper part of the turntable. This utility model can achieve quick orientation and marking of the positioning holes on different welding wire spools through the numerical scale markings on the indicator disc, the rotating frame, and the positioning pin at the lower part of the rotating frame. This facilitates the operator to quickly and accurately install new welding wire spools pre-loaded into the indicator disc, and also facilitates efficient disassembly and marking of welding wire spools that need to be disassembled, making the operation more convenient and efficient.

[0006] The positioning frame is U-shaped, with one vertical part of the positioning frame located on the upper part of the turntable, and the other vertical part of the positioning frame fitting against the outer wall of the marking plate. The width of the positioning frame is less than the distance between two adjacent scale markings. This utility model can rotate the positioning frame and rotate the rotating frame together to realize the rotation adjustment of the position of the positioning pin, which facilitates the rapid positioning and angle determination of the welding wire spools with different positioning holes, and facilitates the rapid and efficient installation and positioning of new welding wire spools.

[0007] The turntable has a groove at the bottom, and a slider is slidably installed inside the groove. The lower part of the slider is connected to the upper part of the positioning pin. This utility model can slide along the groove with the positioning pin at the bottom of the slider, which is convenient for the rapid orientation of positioning holes in different diameter ranges, and for the rapid orientation installation or removal of welding wire spools in different positioning hole positions, making the operation more convenient.

[0008] The locating pin has an upper opening that is larger than the lower opening, which facilitates the smooth insertion of the locating pin into the locating hole.

[0009] The upper part of the positioning frame is equipped with a grip, which makes it easy for the operator to hold the positioning frame and rotate the rotating frame and the turntable below it, so as to adjust the position of the positioning pin.

[0010] The grip part has a cylindrical structure.

[0011] The lowest point of the locating pin is lower than the lowest point of the marking plate, which facilitates pre-alignment with the locating hole position for quick installation and guidance of the locating pin.

[0012] The upper part of the label plate is also evenly distributed with multiple light-removal holes, which helps to reduce the weight of the label plate.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. Solves the problem of low positioning accuracy and greatly improves disassembly and assembly efficiency: This utility model can quickly align the welding wire spool positioning hole with the positioning pin through the scale markings on the marking plate and the positioning frame through directional adjustment, avoiding the tedious operation of repeated rotation alignment in the past; the conical structure and height design of the positioning pin form a dual guide, which greatly shortens the disassembly and assembly time of a single time, greatly improves efficiency, and ensures the continuity of the production line.

[0014] 2. Solve the problem of insufficient adaptability and improve versatility: This utility model can flexibly adjust the horizontal position of the positioning pin by sliding the slider along the slide groove, and is compatible with various welding wire spools with positioning hole diameters ranging from 5-20mm and positioning hole spacing from 100-500mm. There is no need to change auxiliary tools, reducing equipment investment costs and meeting the needs of rapid switching of multiple specifications of welding wire.

[0015] 3. Solve the problem of laborious operation and improve safety: This utility model can provide a stable force point through the cylindrical grip part to avoid slipping; the marking plate is made of aluminum alloy and has light removal holes, and the overall weight is reduced by 40%-60% compared with traditional metal auxiliary tools, making operation more labor-saving, while reducing the risk of equipment falling and improving work safety.

[0016] 4. Solve the problem of poor positioning and guidance, and improve the success rate of disassembly and assembly: This utility model can pre-guide the positioning pin by having its lowest point lower than the marking plate and extending it into the positioning hole area in advance; the upper flared opening expands the alignment tolerance range, and even if there is a slight angular deviation, it can be inserted smoothly, greatly reducing the jamming rate; the lower cylindrical structure fits tightly with the positioning hole, ensuring that the welding wire spool does not loosen after installation, and improving the stability of welding wire feeding.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0020] like Figure 1-4 As shown: This embodiment provides a quick-assembly and disassembly structure for a welding wire spool, including a marking disc 100. The outer wall of the marking disc 100 is provided with numerical scale markings 101. A through hole 102, adapted to the shaft hole of the welding wire spool, is opened on the axis of the marking disc 100, allowing it to be fitted onto the welding wire spool shaft for positioning. Circular light-removing holes 104 are evenly distributed on the upper part to further reduce weight and operational load. A rotating groove 103 is opened in the top side wall of the marking disc 100, and a rotating frame 200 is arranged inside the rotating groove 103. A turntable 300 is arranged at the lower part of the rotating frame 200, and a positioning pin 400, adapted to the positioning hole of the welding wire spool, is arranged at the lower part of the turntable 300. A positioning frame 500, coinciding with the axis of the positioning pin 400, is arranged at the upper part of the turntable 300. The marking disc 100 is made of ABS engineering plastic by injection molding, and the scale markings 101 are made of... Laser engraving is applied to the outer wall of the marking disc 100 with a scale accuracy of 1° to ensure clear and accurate directional readings. The rotating frame 200 and the turntable 300 are integrally stamped from 304 stainless steel. The rotating groove 103 is an annular groove, and the clearance between the rotating frame 200 and the inner wall of the rotating groove 103 is ≤0.1mm to ensure that the rotating frame 200 drives the turntable 300 to rotate smoothly. This utility model can use the numerical scale markings 101 on the marking disc 100, in conjunction with the rotating frame 200 and the positioning pins 400 at the bottom of the rotating frame 200, to quickly orient and mark the positioning holes on different welding wire discs. This allows operators to quickly and accurately install new welding wire discs pre-loaded into the marking disc 100, and also facilitates efficient disassembly and positioning marking of welding wire discs that need to be disassembled, making the operation more convenient and efficient.

[0021] According to one embodiment of the present invention, such as Figure 1-4As shown, the positioning frame 500 is U-shaped. One of the vertical parts of the positioning frame 500 is located on the upper part of the turntable 300, and the other vertical part of the positioning frame 500 is in contact with the outer wall of the marking plate 100. The width of the positioning frame 500 is less than the distance between two adjacent scale markings 101. This utility model can rotate the positioning frame 500 and the rotating frame 200 together to adjust the position of the positioning pin 400, which facilitates the rapid positioning and angle setting of the welding wire spools with different positioning holes, and facilitates the rapid and efficient installation and positioning of new welding wire spools.

[0022] According to another embodiment of the present invention, such as Figure 1 and Figure 4 As shown, a groove 301 is provided at the lower part of the turntable 300. A slider 600 is slidably arranged inside the groove 301. The lower part of the slider 600 is connected to the upper part of the positioning pin 400. The groove 301 is a T-shaped groove, and the slider 600 is a T-shaped block adapted to the groove 301. Both are made of nylon 66 material. The outer side of the slider 600 is coated with polytetrafluoroethylene to reduce sliding friction and improve adjustment smoothness. This utility model allows the slider 600 to slide along the groove 301 with the positioning pin 400 below it, which is convenient for quick orientation of positioning holes in different diameter ranges and for quick orientation installation or removal of welding wire spools in different positioning hole positions, making operation more convenient.

[0023] The positioning pin 400 has a structure where the upper opening is larger than the lower opening. The positioning pin 400 is made of No. 45 steel after quenching and tempering. The upper opening is trumpet-shaped with a taper of 15°. The lower part is cylindrical, which is used to smoothly insert into the positioning hole of the welding wire spool and ensure the stability of the fit. This makes it easy to smoothly insert the positioning pin 400 into the positioning hole.

[0024] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the upper part of the positioning frame 500 is provided with a gripping part 700. The gripping part 700 has a cylindrical structure. The positioning frame 500 is made of Q235 steel and is fixedly connected to the turntable 300 by arc welding. The gripping part 700 is a nitrile rubber sleeve fitted on the upper part of the positioning frame 500. The surface is provided with anti-slip texture to improve gripping comfort and anti-slip effect. This makes it easy for the operator to grip the positioning frame 500 and rotate the rotating frame 200 and the turntable 300 below it, and to adjust the position of the positioning pin 400.

[0025] The lowest point of the positioning pin 400 is lower than the lowest point of the marking disc 100, which facilitates the pre-alignment of the positioning hole position to achieve quick installation and guidance of the positioning pin 400.

[0026] According to another embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the upper part of the marking disk 100 is also evenly provided with a plurality of light removal holes 104, which are evenly distributed along the circumference of the marking disk 100, and the number of them is 4-12. Figure 3 As shown, there are 8 light holes 104, which are used to reduce the weight of the labeling disk 100 and reduce the operating load, thus making it easier to reduce the weight of the labeling disk 100.

[0027] Working principle and usage of this utility model: First, it should be clarified that the quick-release device involved in this utility model is mainly used for the quick disassembly and installation of cable reels with positioning holes. This utility model takes the operation of welding wire reels in the disassembly and assembly process as an example to explain its working principle and usage method in detail. The working principle is as follows: This invention achieves rapid assembly and disassembly of the welding wire reel through the coordinated operation of "marking orientation - position adjustment - guiding positioning". The specific principle is as follows: The scale orientation principle marking disk 100 is fitted with the through hole 102 on the welding wire spool shaft. When the rotating frame 200 rotates along the rotating groove 103, the positioning frame 500 drives the positioning pin 400 to rotate synchronously. The part of the positioning frame 500 that fits against the outer side of the marking disk 100 can be used as a pointer to align with the numbers on the scale marking 101, so as to achieve precise adjustment of the angle of the positioning pin 400 and quickly match the angle position of the positioning hole of the welding wire spool.

[0028] The T-shaped groove 301 at the bottom of the multi-specification adaptability turntable 300 and the slider 600 form a sliding pair. Pushing the slider 600 can change the radial distance of the positioning pin 400 to adapt to the positioning holes of welding wire spools of different diameters. The polytetrafluoroethylene coating on the surface of the slider 600 reduces frictional resistance and ensures smooth adjustment, which can be completed without tools.

[0029] The guiding and positioning principle is that the lowest point of the positioning pin 400 is lower than that of the marking plate 100. During installation, it can be inserted into the area where the positioning hole of the welding wire spool is located in advance to form a preliminary guide. The upper flared opening expands the alignment range and guides the positioning pin 400 to be smoothly inserted into the positioning hole. The lower cylindrical structure is interference-fitted with the positioning hole to achieve a firm positioning of the welding wire spool.

[0030] The labor-saving operation principle and the non-slip grip 700 provide a comfortable force application point and reduce slippage during operation; the plastic material of the marking plate 100 and the design of the light-removing hole 104 reduce the overall weight and reduce the load on the operator's hands; the lever arm design of the U-shaped positioning frame 500 makes rotation more effortless and further improves the ease of operation.

[0031] The usage method is as follows: The specific steps for using this device are as follows; it is simple to operate and suitable for batch operations: Equipment preparation and inspection: Check the status of each component: confirm that the rotating frame 200 rotates smoothly, the slider 600 slides without jamming, the positioning pin 400 is not deformed, and the scale mark 101 is clear; according to the diameter of the positioning hole of the welding wire spool to be disassembled, push the slider 600 along the slide groove 301 to adjust the position of the positioning pin 400 so that it matches the diameter of the positioning hole.

[0032] For the installation and orientation of the marking disc 100, align the through hole 102 of the marking disc 100 with the shaft hole of the welding wire spool, and fit it onto the shaft of the welding wire spool, ensuring that the marking disc 100 is in close contact with the surface of the welding wire spool. The operator holds the marking disc 100 with one hand and grasps the grip part 700 of the positioning frame 500 with the other hand. Rotate the positioning frame 500 to drive the turntable 300 and the positioning pin 400 to rotate synchronously. Observe the scale numbers aligned with the part of the positioning frame 500 that is in contact with the marking disc 100 until the positioning pin 400 is aligned with the angle direction of the positioning hole of the welding wire spool.

[0033] During the wire spool installation, keep the positioning pin 400 aligned with the positioning hole angle, and push the wire spool together with the marking plate 100 toward the positioning shaft of the wire feeding mechanism of the welding machine. With its own height advantage and the guiding effect of the trumpet-shaped opening, the positioning pin 400 smoothly inserts into the positioning hole of the wire feeding mechanism. Continue to push the wire spool until the wire spool shaft hole is fully engaged with the positioning shaft of the wire feeding mechanism to complete the installation.

[0034] During the wire spool disassembly operation, the operator grasps the gripping part 700 of the positioning frame 500, rotates the positioning frame 500 in the opposite direction, causing the positioning pin 400 to rotate out of the positioning hole of the wire feeding mechanism; grasps the marking plate 100 or the edge of the wire spool, and pulls it outward to disengage the wire spool shaft hole from the positioning shaft of the wire feeding mechanism, thus completing the disassembly.

[0035] After the device is reset and stored, adjust the slider 600 to the center position of the positioning pin 400, rotate the positioning frame 500 to align the positioning pin 400 with the scale "0"; clean the dust or welding wire debris from the surface of the positioning pin 400, and place the device and welding wire spool together on a dry and ventilated storage rack to avoid damage to the components.

[0036] This invention enables rapid disassembly and efficient installation of welding wire reels by designing a quick disassembly and assembly structure. It solves the problem that welding wire reels of different specifications or batches may have differences in the angle and number of positioning holes relative to the shaft holes. In traditional disassembly and assembly, the operator needs to repeatedly rotate the welding wire reel to find the position of the positioning holes, which results in difficulties in orienting the positioning holes and long disassembly and assembly time. Especially in batch operations, the average time for a single disassembly and assembly is greatly increased, which seriously reduces production efficiency.

[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
