Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and more specifically relates to a hoop welding jig that is convenient for fixing. Background Technique

[0002] A hoop welding jig is a tool or device specifically used for welding hoops, and it plays an important role as one of the most common iron accessories in the power system. The design of the hoop requires welding a special-shaped rib plate at the arc bending part to enhance its strength. The design and manufacture of this welding jig take into account the dimensional coordinate points of the outer shape of the welded parts to ensure the accuracy and efficiency of the welding process.

[0003] The existing hoop welding jig has no fixing function. This indicates that the hoop welding jig may not be able to meet specific welding requirements, lacks targeted design, and has no structure for fixing the hoop during welding, which greatly affects the flexibility of use and welding efficiency. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a hoop welding jig that is convenient for fixing, which has the advantage of being convenient for fixing.

A first sliding rod is arranged in the through holes. A first spring is sleeved outside the first sliding rod. A clamping plate is arranged at one end of the first sliding rod close to the hoop plate. The two ends of the first spring are respectively fixedly connected with the installation part and the clamping plate;

[0007] Fixing parts are respectively arranged on the front and rear sides of the welding plate. A number of second through holes are provided in the fixing parts. A second sliding rod is arranged in the second through holes. A second spring is sleeved outside the second sliding rod. A fixing plate is arranged at one end of the second sliding rod close to the hoop plate. The two ends of the second spring are respectively fixedly connected with the fixing plate and the fixing part.

[0008] The advantages of this solution are at least as follows: To ensure the positioning and limiting of the hoop component during the welding process, the welding jig of the present utility model is provided with clamping plates on both the front and rear sides of the hoop plate. When welding is required, first place the hoop component between the clamping plates, and the clamping plates apply pressure to the hoop component due to the principle of spring one, thereby strengthening the hoop component to a certain extent. By using structural components such as the mounting part, clamping plates, and spring one in cooperation, the hoop component can be firmly fixed at the corresponding support points, thereby improving the stability of the entire structure. This fixing method can ensure the construction efficiency during the welding process. By providing a fixing plate on the welding plate, and the fixing plate cooperating with spring two, it can further strengthen the wing plate that needs to be welded to the hoop component, ensuring that the wing plate is stably strengthened on the welding plate, ensuring the position and attitude of the welded parts, thereby guaranteeing the welding quality of the contact surface between the hoop component and the wing plate, and avoiding welding defects caused by inaccurate position or movement of the wing plate, which can greatly improve the construction efficiency. The design of the clamping plates and the fixing plate not only ensures the stability of the hoop but also facilitates the operation of the construction personnel and shortens the construction period.

[0009] The present utility model is further configured such that: on the side of the welding plate away from the hoop plate, there are respectively provided fastening parts, the fastening parts are provided with threaded holes, screw rods are threadedly connected in the threaded holes, one end of each screw rod is provided with a connecting plate, the end of the connecting plate is rotatably connected with a fastening plate, and the end of the screw rod away from the fastening plate is fixedly connected with an adjusting part.

[0010] The advantages of this solution are at least as follows: By adjusting the adjusting part, the fastening plate can assist in fixing the wing plate. With the dual fixation of the fixing plate, the contact surface between the hoop component and the wing plate can be made closer, improving the welding accuracy.

[0011] The present utility model is further configured such that: on the end face of the fastening plate, there are provided a number of spring threes, and one end of each spring three away from the fastening plate is fixedly connected with a buffer plate.

[0012] The advantages of this solution are at least as follows: By providing the buffer plate, when the fastening plate makes secondary auxiliary fixation on the wing plate, the buffer plate can well relieve the direct pressure of the fastening plate on the wing plate, avoiding excessive pressure on the wing plate caused by over-adjusting the fastening plate and resulting in sliding of the mutual contact surface between the wing plate and the hoop component.

[0013] The present utility model is further configured such that: on the welding plate, there is provided a chute, and on the end face of the fastening plate on the side close to the welding plate, there extends a slider that cooperates with the chute.

[0014] The advantages of this solution are at least as follows: By providing a sliding groove and a sliding block, even if the screw becomes loose due to long-term use of the threaded hole, the sliding block provided on the fastening plate can still be in sliding fit with the sliding groove, ensuring that the fastening plate moves linearly towards the wing plate, avoiding uneven fixing force of the fastening plate on the wing plate, preventing the wing plate from being skewed, and reducing the welding accuracy.

[0015] The present utility model is further configured such that: Limiting portions are respectively provided at the ends of the first sliding rod and the second sliding rod away from the hoop plate.

[0016] The advantages of this solution are at least as follows: The provision of the limiting portions can ensure that the sliding processes of the first sliding rod and the second sliding rod do not deviate from the mounting portion and the fixing portion, and are used to restrict or limit the directional displacement of the first sliding rod and the second sliding rod.

[0017] The present utility model is further configured such that: A rubber strip is provided on the end face of the clamping plate near the hoop plate.

[0018] The advantages of this solution are at least as follows: By providing the rubber strip, the friction between the clamping plate and the hoop assembly can be increased, and it also has a good fixing function, which can ensure the tight connection between the clamping plate and the component, and prevent the hoop assembly from sliding on the hoop plate.

[0019] The present utility model is further configured such that: Anti-slip pads are respectively embedded on the end faces of the buffer plate and the fixing plate on the side near the hoop plate.

[0020] The advantages of this solution are at least as follows: By providing the anti-slip pads, on the one hand, the friction between the fixing plate and the buffer plate and the wing plate can be increased, and on the other hand, it can also prevent the spatter during the welding process from sticking to the contact surfaces between the fastening plate, the fixing plate and the wing plate and causing adhesion to the wing plate. It also has high elasticity and can maintain flexibility even in a low-temperature environment, avoiding affecting the construction efficiency.

[0021] The present utility model is further configured such that: Both the hoop plate and the welding plate are made of high-carbon steel material.

[0022] The advantages of this solution are at least as follows: Due to the non-sticky property of the high-carbon steel material, even if the spatter during the welding process adheres to the hoop plate or the welding plate, it can be relatively easily cleaned, ensuring the smoothness and flatness of the welding plate and improving the welding quality.

[0023] In summary, the present utility model has at least the following advantages:

[0024] 1. By setting the fastening part and adjusting the adjusting part, the fastening plate can assist in fixing the wing plate. With the dual fixation of the fixing plate, the contact surface between the hoop assembly and the wing plate can be made closer, improving the welding accuracy. By setting the buffer plate, when the fastening plate makes a secondary auxiliary fixation on the wing plate, the buffer plate can well relieve the direct pressure of the fastening plate on the wing plate, avoiding excessive pressure on the wing plate caused by over-adjusting the fastening plate and preventing sliding on the mutual contact surface between the wing plate and the hoop assembly.

[0025] 2. By setting the chute and the slider, even if the screw rod becomes loose due to long-term use of the threaded hole, the slider on the fastening plate can still make a sliding fit with the chute, ensuring that the fastening plate moves linearly towards the wing plate, avoiding uneven fixing force of the fastening plate on the wing plate and preventing the wing plate from being skewed, which may lead to a decrease in welding accuracy. The setting of the limiting part can ensure that the sliding processes of the first slide bar and the second slide bar do not deviate from the installation part and the fixing part, and is used to restrict or limit the directional displacement of the first slide bar and the second slide bar.

[0026] 3. By setting the rubber strip, the friction between the clamping plate and the hoop assembly can be increased, and it also has a good fixing function, which can ensure the tight connection between the clamping plate and the component, preventing the hoop assembly from sliding on the hoop plate. By setting the anti-slip pad, on the one hand, it can not only increase the friction between the fixing plate and the buffer plate and the wing plate, on the other hand, it can also prevent the splashes during the welding process from sticking to the mutual contact surfaces of the fastening plate, the fixing plate and the wing plate, resulting in adhesion to the wing plate. It also has high elasticity and can maintain flexibility even in low-temperature environments, avoiding affecting the construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A hoop welding fixture convenient for fixing, as Figure 1 shown, includes a fixture body 1. The fixture body 1 includes a hoop plate and a welding plate 3. Installation parts 4 are respectively extended and arranged on the front and rear sides of the hoop plate. A number of through holes are provided in the installation parts 4. A first sliding rod 5 is arranged in the through holes. A first spring 6 is sleeved outside the first sliding rod 5. A clamping plate 7 is arranged at one end of the first sliding rod 5 close to the hoop plate. The two ends of the first spring 6 are respectively fixedly connected with the installation part 4 and the clamping plate 7. Fixing parts 8 are respectively arranged on the front and rear sides of the welding plate 3. A number of second through holes are provided in the fixing parts 8. A second sliding rod 9 is arranged in the second through holes. A second spring 10 is sleeved outside the second sliding rod 9. A fixing plate 11 is arranged at one end of the second sliding rod 9 close to the hoop plate. The two ends of the second spring 10 are respectively fixedly connected with the fixing plate 11 and the fixing part 8. When welding is required, first place the hoop assembly between the clamping plates 7. The clamping plates 7 apply pressure to the hoop assembly due to the principle of the first spring 6, so as to reinforce the hoop assembly to a certain extent. Through the cooperation of structural parts such as the installation part 4, the clamping plate 7 and the first spring 6, the hoop assembly can be firmly fixed on the corresponding support points, thereby improving the stability of the whole structure. This fixing method can ensure the construction efficiency during the welding process. By providing the fixing plate 11 on the welding plate 3, the fixing plate 11 and the second spring 10 cooperate with each other to further reinforce the wing plate that needs to be welded with the hoop assembly, ensure that the wing plate is stably reinforced on the welding plate 3, can ensure the position and posture of the welded parts, thereby ensuring the welding quality of the contact surface between the hoop assembly and the wing plate, and can avoid welding defects caused by inaccurate position or movement of the wing plate, and can greatly improve the construction efficiency. The design of the clamping plate 7 and the fixing plate 11 not only ensures the stability of the hoop, but also is convenient for the construction personnel to operate and shortens the construction period.

[0033] On the side of the welding plate 3 far from the hoop plate, tightening parts 12 are respectively arranged. Threaded holes are provided in the tightening parts 12.

By providing the rubber strip 22, the friction between the clamping plate 7 and the hoop assembly can be increased, and it also has a good fixing function, ensuring a tight connection between the clamping plate 7 and the component, and preventing the hoop assembly from slipping on the hoop plate.

[0038] Anti-slip pads 23 are respectively embedded in the end faces of the buffer plate 18 and the fixing plate 11 toward the hoop plate. By providing the anti-slip pads 23, on the one hand, it can not only increase the friction between the fixing plate 11 and the buffer plate 18 and the wing plate, but on the other hand, it can also prevent the splashes during the welding process from sticking to the contact surfaces between the fastening plate 15, the fixing plate 11 and the wing plate and causing adhesion to the wing plate. It also has high elasticity and can maintain flexibility even in low-temperature environments, avoiding affecting the construction efficiency.

[0039] Both the hoop plate and the welding plate 3 are made of high-carbon steel material. Due to the non-sticky characteristics of the high-carbon steel material, even if the splashes during the welding process adhere to the hoop plate or the welding plate 3, it can be relatively easily cleaned, ensuring the smoothness of the welding plate 3 and improving the welding quality.

[0040] The working process and beneficial effects of the present utility model are as follows: To ensure the positioning and limiting of the hoop assembly during the welding process, the welding jig of the present utility model is provided with clamping plates 7 on both the front and rear sides of the hoop plate. When welding is required, first place the hoop assembly between the clamping plates 7.

This fixing method can ensure the construction efficiency during the welding process. By providing a fixing plate 11 on the welding plate 3, and the fixing plate 11 cooperating with spring 2 10, further reinforcement can be provided to the wing plate that needs to be welded to the hoop assembly, ensuring that the wing plate is stably reinforced on the welding plate 3, being able to ensure the position and attitude of the welded parts, thereby guaranteeing the welding quality of the contact surface between the hoop assembly and the wing plate, and avoiding welding defects caused by inaccurate position or movement of the wing plate, which can greatly improve the construction efficiency. The design of the clamping plates 7 and the fixing plate 11 not only ensures the stability of the hoop but also facilitates the operation of the construction personnel, shortening the construction cycle. The installation and fixing structure on the hoop welding jig can not only improve the welding accuracy and efficiency, enhance the rigidity and stability of the structure, but also improve the product quality, improve the working conditions, and has good versatility and flexibility, being applicable to various welding technologies.
