Description

Technical Field

[0001] This utility model relates to the field of fixtures, and in particular to a fixture for controlling the deformation of Stellite weld overlay parts. Background Technology

[0002] Stellite is a hard alloy resistant to various types of wear, corrosion, and high-temperature oxidation. It is commonly referred to as a cobalt-chromium-tungsten (molybdenum) alloy or a cobalt-based alloy. Stellite alloys are primarily composed of cobalt, containing significant amounts of nickel, chromium, and tungsten, and small amounts of molybdenum, niobium, tantalum, titanium, lanthanum, and occasionally iron. Depending on the alloy composition, they can be made into welding wires or powders for hardfacing, thermal spraying, and spray welding, or into castings, forgings, and powder metallurgy parts.

[0003] Currently, Chinese utility model patent CN219293741U discloses an anti-deformation fixture for automotive parts processing. While this fixture can fix parts and prevent displacement during Stellite welding, it has other problems in use, such as poor side deformation prevention. The heat generated during welding causes localized thermal expansion, leading to upward warping on the sides, increasing the burden of subsequent repairs. Furthermore, it lacks welding position adjustment functionality. When the welding position of the part is irregular, personnel cannot complete the full welding from the front of the fixture; they must first complete the welding area on the front, remove the part, rotate it once, and then re-fix it, which is time-consuming and labor-intensive. To solve these problems, we propose a Stellite welding part deformation control fixture. Utility Model Content

[0004] The purpose of this invention is to provide a deformation control fixture for Stellite weld overlay parts, which solves the problems of poor control effect and lack of welding position adjustment function of existing fixtures.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a Stellite weld overlay part deformation control fixture, including a fixed frame and a clamping mechanism. The top of the fixed frame is provided with two fixed plates, and a threaded rod is threadedly connected to the top of the fixed plate. A control block is installed at the bottom end of the threaded rod, and guide rods are symmetrically welded to the top of the control block. A housing is provided on one side of the fixed frame, and a rotating shaft welded to the fixed frame is rotatably connected inside the housing. A gear is fixedly sleeved on the surface of the rotating shaft, and a limit plate is engaged with the top of the gear. A limit spring is bolted between the top of the limit plate and the housing through a spring fixing plate.

[0006] The above technical solution can improve the control effect of parts, prevent the sides of parts from warping upward due to heat, ensure the quality of parts after welding, and has high practicality. At the same time, it can also have the function of adjusting the welding position, which is simple and convenient to operate, improves the work efficiency of personnel, and has good flexibility.

[0007] The present invention is further configured such that: the clamping mechanism includes a bidirectional screw, one end of which is rotatably connected to the inside of the fixed frame via a bearing; two threaded plates are threadedly connected to the surface of the bidirectional screw; two clamping plates are provided on the top of the fixed frame; connecting plates are symmetrically bolted to the back-to-back sides of the two clamping plates; and the bottom of the connecting plate is bolted to the top of the threaded plate.

[0008] By adopting the above technical solution, the parts can be fixed by setting up a bidirectional screw, a threaded plate, a clamping plate and a connecting plate, and the parts can be prevented from shifting during the welding process.

[0009] The present invention is further configured such that: a slide rail is bolted inside the fixed frame, and a slider that is slidably connected to the slide rail is welded to the bottom of the threaded plate.

[0010] By adopting the above technical solution, the threaded plate can be limited by the setting of slide rail and slider, preventing the threaded plate from flipping over during left and right movement.

[0011] The present invention is further configured such that: the other end of the bidirectional screw extends through to the outside of the fixed frame and is equipped with a first throttle, and the top end of the threaded rod is equipped with a second throttle.

[0012] By adopting the above technical solution, the setting of the first and second throttles facilitates the rotation of the bidirectional screw and the threaded rod by personnel.

[0013] The present invention is further configured such that: telescopic rods are symmetrically installed between the top of the limiting plate and the shell.

[0014] By adopting the above technical solution, the limit plate can be limited by the telescopic rod to prevent it from tilting during its up and down movement.

[0015] The present invention is further configured such that: a fixing rod is welded to the top of the limiting plate, and the other end of the fixing rod extends through to the outside of the housing and is fitted with a pull plate.

[0016] By adopting the above technical solution, the setting of the fixing rod and the pull plate makes it easy for personnel to pull the limiting plate upward to separate it from the gear.

[0017] The present invention is further configured such that: mounting plates are installed on both the front and back of the housing, and mounting holes are provided on the top of the mounting plates.

[0018] By adopting the above technical solution, the installation plate and mounting holes make it easy for personnel to fix the housing to the workbench with screws.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model involves first placing the part on a fixed frame, then holding the first handle to rotate the bidirectional screw. The rotation of the bidirectional screw causes two threaded plates and a clamping plate to move inwards synchronously. The inward movement of the clamping plates initially clamps and fixes the part. Then, holding the second handle rotates the threaded rod. The rotation of the threaded rod causes a control block to move downwards, pressing against the side edge of the part. This improves the control of the part, prevents the side edge from warping upwards due to heat, and ensures the quality of the part after welding. It is highly practical.

[0021] 2. This utility model allows users to grasp the pull plate and pull it upwards. When the pull plate is pulled up, the fixing rod will drive the limiting plate to move upwards. When the limiting plate moves upwards, it will not only compress the limiting spring, causing it to deform and contract, but also separate from the gear, releasing the restriction on the gear. When the pull plate is pulled up to the bottom, the other hand can grasp the fixing frame and rotate it to the appropriate direction. It has the function of adjusting the welding position, is simple and convenient to operate, improves the work efficiency of personnel, and has good flexibility. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] refer to Figure 1 and Figure 2The Stellite weld overlay deformation control fixture includes a fixed frame 1 and a clamping mechanism 2. The fixed frame 1 has two fixed plates 3 on its top, with threaded rods 4 threadedly connected to the top of each plate 3. A control block 5 is installed at the bottom of the threaded rod 4, and guide rods 6 are symmetrically welded to the top of the control block 5. The fixture works by first placing the part onto the fixed frame 1, then holding the first handle 14 to rotate the bidirectional screw 21. The rotation of the bidirectional screw 21 causes the two threaded plates 22 and the clamping plate 23 to move inwards synchronously, initially clamping and fixing the part. Then, holding the second handle 15 rotates the threaded rod 4, causing the control block 5 to move downwards and press against the side edge of the part. This improves the control effect on the part, prevents the side edge from warping upwards due to heat, ensures the quality of the weld overlay, and is highly practical.

[0029] refer to Figure 1 and Figure 2 The clamping mechanism 2 includes a bidirectional screw 21. One end of the bidirectional screw 21 is rotatably connected to the inside of the fixed frame 1 via a bearing. Two threaded plates 22 are threadedly connected to the surface of the bidirectional screw 21. Two clamping plates 23 are provided on the top of the fixed frame 1. Connecting plates 24 are symmetrically bolted to the back-to-back sides of the two clamping plates 23. The bottom of the connecting plate 24 is bolted to the top of the threaded plate 22. Through the arrangement of the bidirectional screw 21, threaded plates 22, clamping plates 23 and connecting plates 24, the parts can be fixed to prevent them from shifting during the welding process.

[0030] refer to Figure 2 The fixed frame 1 is bolted with a slide rail 12. The bottom of the threaded plate 22 is welded with a slider 13 that is slidably connected to the slide rail 12. By setting the slide rail 12 and the slider 13, the threaded plate 22 can be limited to prevent it from flipping over during left and right movement.

[0031] refer to Figure 1 and Figure 2 The other end of the bidirectional screw 21 extends through the outside of the fixed frame 1 and is equipped with a first throttle 14. The top of the threaded rod 4 is equipped with a second throttle 15. The setting of the first throttle 14 and the second throttle 15 makes it easy for personnel to rotate the bidirectional screw 21 and the threaded rod 4.

[0032] Brief description of the usage process: First, place the part on the fixed frame 1. After placing the part, hold the first throttle 14 to drive the bidirectional screw 21 to rotate. When the bidirectional screw 21 rotates, it will drive the two threaded plates 22 and the clamping plate 23 to move inward synchronously. When the clamping plate 23 moves inward, it will initially clamp and fix the part. Then, hold the second throttle 15 to drive the threaded rod 4 to rotate. When the threaded rod 4 rotates, it will drive the control block 5 to move down and press the side edge of the part.

[0033] Example 2:

[0034] refer to Figure 1 , Figure 2 and Figure 3 The Stellite welding component deformation control fixture has a housing 7 on one side of the fixed frame 1. The housing 7 is rotatably connected to a rotating shaft 8 welded to the fixed frame 1. A gear 9 is fixedly sleeved on the surface of the rotating shaft 8. A limit plate 10 is engaged with the top of the gear 9. A limit spring 11 is bolted between the top of the limit plate 10 and the housing 7 through a spring fixing plate. By grasping the pull plate 18 and pulling it upward, the pull plate 18 will drive the limit plate 10 to move upward through the fixing rod 17. When the limit plate 10 moves upward, it will not only compress the limit spring 11, causing it to deform and contract, but also separate from the gear 9, releasing the restriction on the gear 9. After the pull plate 18 is pulled up to the bottom, the other hand can grasp the fixed frame 1 and rotate it to the appropriate direction. It has the function of adjusting the welding position, is simple and convenient to operate, improves the work efficiency of personnel, and has good flexibility.

[0035] refer to Figure 3 A telescopic rod 16 is symmetrically installed between the top of the limiting plate 10 and the housing 7. The telescopic rod 16 can limit the limiting plate 10 and prevent the limiting plate 10 from tilting during the up and down movement.

[0036] refer to Figure 1 , Figure 2 and Figure 3 A fixing rod 17 is welded to the top of the limiting plate 10. The other end of the fixing rod 17 extends through to the outside of the housing 7 and is fitted with a pull plate 18. With the fixing rod 17 and the pull plate 18, it is easy for personnel to pull the limiting plate 10 upward to separate it from the gear 9.

[0037] refer to Figure 1 Mounting plates 19 are installed on both the front and back of the housing 7. Mounting holes are provided on the top of the mounting plates 19. The mounting plates 19 and the mounting holes make it easy for personnel to fix the housing 7 to the workbench with screws.

[0038] Brief description of the usage process: By grasping the pull plate 18 with your hand and pulling it upward, the pull plate 18 will be fixed by the fixing rod 17 and drive the limiting plate 10 to move upward. When the limiting plate 10 moves upward, it will not only compress the limiting spring 11 to deform and contract, but also separate from the gear 9 to release the restriction on the gear 9. After the pull plate 18 is pulled up to the bottom, grasp the fixing frame 1 with your other hand and rotate it to the appropriate direction.
