Description

Technical Field

[0001] This utility model relates to the field of bulldozer bearing processing technology, and in particular to a convenient welding fixture for bulldozer bearings. Background Technology

[0002] Because bulldozer bearings are welded from bulldozer valve supports and positioning plates, stress deformation occurs during conventional splicing and welding. This stress is released and deformation occurs after machining to remove excess material. The difficulty in welding bulldozer bearings lies in the thin and lightweight steel frame structure, which poses a risk of welding deformation and detachment. High positional accuracy is required, with height control within 0.1mm and lateral positional error within 0.2mm as specified in the drawings. Conventional arc welding cannot guarantee deformation prevention, and positional accuracy cannot be effectively guaranteed. Subsequent use of gas-shielded welding significantly improved the welding process, but positional accuracy still could not be guaranteed. This resulted in uneven milling surfaces or uneven machining stops during subsequent processing, severely affecting the flexibility of gear engagement, causing jamming, and failing to meet the design accuracy requirements, ultimately leading to product scrap. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a convenient welding fixture for bulldozer supports, which addresses the above-mentioned shortcomings of the existing technology. It can quickly perform clamping and welding while ensuring positional accuracy, and effectively prevents subsequent deformation. It is convenient to use and highly practical.

[0004] The technical solution adopted by this utility model is: a convenient welding fixture for a bulldozer support, including a base plate, with limiting plates at both ends of the rear side of the base plate that are perpendicularly connected to the base plate, and side plates perpendicular to the base plate on both sides of the limiting plates. The base plate is provided with two pins for positioning the bulldozer support, and the pins are perpendicularly connected to the base plate. The side plates are provided with positioning grooves in the middle that correspond to the positioning plates, and the positioning plates are installed in the positioning grooves. The rear side of the side plates is provided with a clamping assembly for pressing the positioning plates.

[0005] As a further improvement, the clamping assembly includes a clamping plate and a clamping screw. The clamping plate is fixedly arranged on the rear side of the side plate, and the lower end of the clamping plate is connected to the base plate. The clamping screw is threadedly connected to the clamping plate and passes through the positioning groove to contact the positioning plate.

[0006] Furthermore, the length of the positioning groove is the same as the width of the positioning plate.

[0007] Furthermore, multiple pin holes are provided on both sides of the base plate, and the pins are movably inserted into the base plate.

[0008] Furthermore, the perpendicularity between the base plate and the limiting plate is between 0.01mm and 0.02mm.

[0009] Furthermore, the base plate and the limiting plate are connected by connecting screws, which pass through the limiting plate and are threaded into the base plate.

[0010] Furthermore, a clearance groove is provided on the side plate below the positioning groove.

[0011] Beneficial effects

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] This utility model discloses a convenient welding fixture for bulldozer supports. In use, the positioning plate is first placed in the positioning groove, then the pins on both sides are inserted into the appropriate pin holes. The bulldozer valve support is then installed on the base plate according to the pin limits. The clamping screws are then tightened, pushing the positioning plate to press against the bulldozer valve support, ensuring a tight and fixed fit between the positioning plate and the support. This effectively prevents tensile deformation after welding. The pins serve to fix and press the bulldozer valve support, preventing loosening and displacement, and ensuring the welding position accuracy of the positioning plate. The side plate, with a positioning groove, ensures the positioning plate is fixed during welding. The positioning groove also ensures a consistent width with the positioning plate, effectively preventing incorrect installation and providing an error-proof function. The entire installation process is simple and quick. The positioning plate and bulldozer valve support are both restricted, effectively guaranteeing positional accuracy. After welding, the clamping screws, side plate, and pins provide limiting and clamping, effectively preventing deformation after welding and improving product quality. This fixture is highly practical and has a wide range of applications. Attached Figure Description

[0018] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0019] See Figure 1-3As shown, this utility model discloses a convenient welding fixture for a bulldozer support, comprising a base plate 1, with limiting plates 2 perpendicularly connected to the rear ends of the base plate 1, and side plates 4 perpendicular to the base plate 1 on the limiting plates 2. The base plate 1 has two pins 5 for positioning a bulldozer valve support 8, which are perpendicularly connected to the base plate 1. The side plates 4 have a positioning groove 10 corresponding to a positioning plate 9 in the middle, and the positioning plate 9 is installed in the positioning groove 10. A clamping assembly for pressing the positioning plate 9 is located on the rear side of the side plates 4. In use, the positioning plate 9 is first placed in the positioning groove 10, then the pins 5 on both sides are inserted into the appropriate pin holes 12. The bulldozer valve support 8 is then installed on the base plate 1 according to the limiting position of the pins 5. Finally, the clamping screws 6 are tightened, which push the positioning plate 9 to press... The bulldozer valve support 8 is tightened to ensure that the positioning plate 9 is firmly fixed to the bulldozer valve support 8, effectively avoiding tensile deformation after welding. The pin 5 is set to fix and press the bulldozer valve support 8, preventing loosening and displacement, and ensuring the welding position accuracy of the positioning plate. The side plate 4 is set, and the positioning groove 10 is opened on the side plate 4 to ensure the welding and fixing of the positioning plate 9. At the same time, the positioning groove 10 ensures that the width matches the positioning plate 9, effectively preventing the positioning plate 9 from being installed incorrectly, and playing a role in preventing errors. The entire installation process is simple and quick. The positioning plate and the bulldozer valve support 8 are restricted, which effectively ensures the position accuracy. After welding, the clamping screw 6, the side plate 4 and the pin 5 are used to limit and press, effectively preventing deformation after welding and improving product quality.

[0020] Specifically, the clamping assembly includes a clamping plate 7 and a clamping screw 6. The clamping plate 7 is fixedly arranged on the rear side of the side plate 4. The lower end of the clamping plate 7 is connected to the base plate 1. The clamping screw 6 is threadedly connected to the clamping plate 7. The clamping screw 6 passes through the positioning groove 10 and contacts the positioning plate 9. Tightening the clamping screw 6 pushes the positioning plate 9 to press the bulldozer valve support 8, ensuring that the positioning plate 9 and the bulldozer valve support 8 are tightly fixed, effectively avoiding tensile deformation after welding.

[0021] Preferably, the length of the positioning groove 10 is the same as the width of the positioning plate 9, which ensures that the width of the positioning plate 9 is consistent with that of the positioning plate 9, effectively avoiding the phenomenon of incorrect installation of the positioning plate 9, and playing a role in preventing errors.

[0022] Furthermore, multiple pin holes 12 are provided on both sides of the base plate 1, and the pins 5 are movably inserted into the base plate 1. Different pin holes 12 can be selected for use according to different models of bulldozer valve supports 8, so that the distance between the pins 5 on both sides is different, thereby meeting the needs of different models of bulldozer valve supports 8.

[0023] Furthermore, the perpendicularity between the base plate 1 and the limiting plate 2 is between 0.01mm and 0.02mm. The perpendicularity of the limiting plate 2 affects the side plate 4, and the perpendicularity of the side plate 4 ensures the quality of the product after welding.

[0024] Furthermore, the base plate 1 and the limiting plate 2 are connected by connecting screws 3. The connecting screws 3 pass through the limiting plate 2 and are threaded to the base plate 1. Using connecting screws 3 facilitates assembly and disassembly.

[0025] Furthermore, a clearance groove 11 is provided on the side plate 4 below the positioning groove 10, which facilitates the installation of the positioning plate 9 in the positioning groove 1 and also facilitates its removal after welding.

[0026] In this embodiment, a convenient welding fixture for a bulldozer support is used by first placing the positioning plate 9 in the positioning groove 10, then inserting the pins 5 on both sides into the appropriate pin holes 12, and then installing the bulldozer valve support 8 on the base plate 1 according to the positioning of the pins 5. Then, tightening the clamping screws 6 pushes the positioning plate 9 to press the bulldozer valve support 8, ensuring that the positioning plate 9 and the bulldozer valve support 8 are tightly fixed together, effectively avoiding tensile deformation after welding. The pins 5 serve to fix and press the bulldozer valve support 8, preventing loosening and displacement. To ensure the welding position accuracy of the positioning plate 9, a side plate 4 is installed with a positioning groove 10. This ensures the positioning plate 9 is fixed during welding and that the positioning groove 10 matches the width of the positioning plate 9, effectively preventing incorrect installation. The entire installation process is simple and quick. Both the positioning plate and the bulldozer valve support 8 are constrained, effectively guaranteeing positional accuracy. After welding, the clamping screws 6, side plate 4, and pins 5 are used for limiting and clamping, effectively preventing deformation after welding and improving product quality. This utility model's convenient welding fixture for bulldozer supports allows for quick clamping and welding while ensuring positional accuracy, effectively preventing subsequent deformation. It is characterized by ease of use and high practicality.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model, and these will not affect the implementation effect of the present utility model or the practicality of the patent.
