Buffer rod surfacing centering tool

Abstract

The utility model relates to the technical field of buffer rod surfacing, in particular to a buffer rod surfacing centering tool which comprises a workbench used for supporting a device. The buffer rod main body is arranged at the upper top end of the workbench; due to the fact that the driving mechanism is arranged, due to the fact that the sizes of the two ends of the buffer rod body are different, in order to improve the stability of the buffer rod body in the machining process, the two ends of the buffer rod body need to be clamped, and due to the fact that the main clamping mechanism and the auxiliary clamping mechanism are the same in structure, when used, the buffer rod body is clamped. One end of the buffer rod body is clamped through the main clamping mechanism, then kinetic energy is switched through the driving mechanism, the kinetic energy of the driving mechanism is switched to the auxiliary clamping mechanism due to the fact that the first threaded rod of the main clamping mechanism has the self-locking performance, and therefore the kinetic energy can be freely switched in the using process; and therefore, the buffer rod main body is further clamped, and the stability in the machining process is ensured.

Description

Technical Field

[0001] This utility model relates to the field of buffer rod overlay welding technology, specifically a buffer rod overlay welding centering tool. Background Technology

[0002] Buffer bar welding is an important surface treatment method in modern machinery manufacturing. It is widely used to improve the wear resistance and extend the service life of components. Buffer bars are typically used to absorb impact loads, reduce vibration and noise during equipment operation, and thus protect other mechanical parts. With the improvement of industrial automation and mechanization, the performance requirements for buffer bars are also becoming increasingly stringent.

[0003] The patent with publication number 1 discloses a wind turbine centering fixture, which includes a support plate and a handle fixedly disposed on one side of the surface of the support plate. It also includes a housing bolted to the surface of the support plate and a lifting mechanism body disposed in the inner cavity of the housing for lifting. A lifting block is fixedly disposed on one side of the surface of the lifting mechanism body. An adjusting plate is disposed in the inner cavity of the lifting block. An adjusting mechanism for changing the angle of the adjusting plate is disposed in the inner cavity of the lifting block.

[0004] In the processing of components such as buffer rods with different dimensions at both ends, it is necessary to ensure their stability during processing in order to guarantee processing accuracy and quality. Currently, there are certain limitations in clamping and fixing such components with different dimensions at both ends. Due to the different dimensions at both ends of the component, clamping only one end is difficult to meet the stability requirements required during processing, which can easily lead to shaking or displacement of the component during processing, thereby affecting processing accuracy and product quality.

[0011] The drive mechanism, located at the top of the worktable, regulates the kinetic energy of the main clamping mechanism and the auxiliary clamping mechanism.

The outer wall of the reciprocating frame is threaded with a limiting pin to limit the position of the connecting frame.

[0014] As a further preferred embodiment of this technical solution, the auxiliary clamping mechanism is disposed at the top of the worktable and located on one side of the main clamping mechanism. The structure of the auxiliary clamping mechanism is the same as that of the main clamping mechanism. The auxiliary clamping mechanism includes two bearing frames symmetrically and fixedly connected to the top of the worktable. A second threaded rod is rotatably sleeved inside the two bearing frames, and the two are rotatably sleeved through the bearing. A second synchronous wheel is fixedly sleeved on the outer wall of the second threaded rod.

[0015] As a further preferred embodiment of this technical solution, a side plate is fixedly connected to the outer side wall of the workbench, and the side plate is integrally formed with the workbench.

[0019] This utility model provides a centering fixture for welding a buffer rod, which has the following advantages:

[0020] This utility model incorporates a driving mechanism that powers both the main and auxiliary clamping mechanisms. Since the two ends of the buffer rod body have different dimensions, both ends need to be clamped to increase stability during processing. Because the main and auxiliary clamping mechanisms have identical structures, the main clamping mechanism first clamps one end of the buffer rod body. Then, the driving mechanism switches the kinetic energy. Due to the self-locking nature of the first threaded rod, the main clamping mechanism transfers its kinetic energy to the auxiliary clamping mechanism. This allows for free switching of kinetic energy during use, further clamping the buffer rod body and ensuring stability during processing. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] This utility model provides a technical solution: such as Figures 1 to 5 As shown, in this embodiment, a buffer rod welding centering fixture includes a worktable 1 for supporting the device; a buffer rod body 4 disposed at the top of the worktable 1; a main clamping mechanism 2 disposed at the top of the worktable 1 and initially limiting the buffer rod body 4; an auxiliary clamping mechanism 3 disposed at the top of the worktable 1 and further limiting the buffer rod body 4, and the main clamping mechanism 2 and the auxiliary clamping mechanism 3 have the same structure; and a driving mechanism 5 disposed at the top of the worktable 1 to regulate the kinetic energy of the main clamping mechanism 2 and the auxiliary clamping mechanism 3.

[0029] Furthermore, the main clamping mechanism 2 and the auxiliary clamping mechanism 3 are also located at the top of the worktable 1, respectively achieving the initial and secondary limiting of the buffer rod body 4. The two have the same structure, which can be easily adjusted and maintained, improving the flexibility and adaptability of the tooling. The drive mechanism 5 is located at the top of the worktable 1 and is mainly responsible for regulating the kinetic energy of the main clamping mechanism 2 and the auxiliary clamping mechanism 3. It can accurately control the clamping force and position to ensure the stability of the buffer rod during the welding process, thereby ensuring the uniformity and consistency of the welding.

[0030] like Figure 1 and Figure 2 As shown, the main clamping mechanism 2 includes two fixed frames 211 symmetrically fixedly connected to the top of the worktable 1. Guide rods 22 are fixedly connected inside the two fixed frames 211. Two bearing frames 21 are symmetrically fixedly connected to the top of the worktable 1. A first threaded rod 23 is rotatably sleeved inside the two bearing frames 21, and the two are rotatably sleeved through the bearing. A first synchronous wheel 24 is fixedly sleeved on the outer wall of the first threaded rod 23.

[0031] Furthermore, the guide rod 22 fixedly connected inside the fixed frame 211 plays a guiding and limiting role, ensuring the smoothness of the clamping and releasing process. The first threaded rod 23 rotatably sleeved inside the bearing frame 21 reduces frictional resistance and improves the flexibility and response speed of the mechanism through the rotation design of the bearing. The first synchronous wheel 24 fixedly sleeved on the outer wall of the first threaded rod 23 is connected to the drive mechanism 5, realizing the synchronous control of the main clamping mechanism 2.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the outer wall of the first threaded rod 23 is symmetrically threaded with two reciprocating frames 25, and the reciprocating frames 25 are slidably connected to the guide rod 22. The upper top of the reciprocating frame 25 is slidably connected with a connecting frame 26. The opposite side of the two connecting frames 26 is fixedly connected with a clamping plate 27 that contacts the outer wall of the buffer rod body 4. The outer wall of the reciprocating frame 25 is threaded with a limiting pin 28 to limit the connecting frame 26.

[0033] Furthermore, the two reciprocating frames 25, symmetrically threaded on the outer wall of the first threaded rod 23, constitute an important moving component of the main clamping mechanism 2. The reciprocating frames 25, through their sliding sleeve design with the guide rod 22, ensure their stability and flexibility during operation, enabling the main clamping mechanism 2 to respond quickly under different working conditions, thereby improving clamping efficiency and accuracy. The limiting pins 28 threaded on the outer wall of the reciprocating frames 25 provide an effective limiting function for the connecting frame 26, ensuring that the reciprocating frames 25 move within a specific range, preventing damage to the mechanism due to excessive movement, and ensuring the controllability of the clamping process.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the auxiliary clamping mechanism 3 is located at the top of the workbench 1 and on one side of the main clamping mechanism 2. The structure of the auxiliary clamping mechanism 3 is the same as that of the main clamping mechanism 2. The auxiliary clamping mechanism 3 includes two bearing brackets 21 symmetrically and fixedly connected to the top of the workbench 1. The two bearing brackets 21 are rotatably sleeved with a second threaded rod 31 inside, and the two are rotatably sleeved through the bearing. The outer wall of the second threaded rod 31 is fixedly sleeved with a second synchronous wheel 32.

[0035] Furthermore, the auxiliary clamping mechanism 3 is located at the top of the worktable 1, on one side of the main clamping mechanism 2, and is designed to further enhance the stability and accuracy of clamping. The auxiliary clamping mechanism 3 includes two bearing brackets 21 that are symmetrically fixedly connected to the top of the worktable 1, providing a stable support base for the second threaded rod 31.

[0036] like Figure 1 , Figure 3 and Figure 4As shown, a side plate 11 is fixedly connected to the outer wall of the worktable 1, and the side plate 11 is integrally formed with the worktable 1. The drive mechanism 5 includes a drive motor 51 fixedly connected to the top of the side plate 11. A drive shaft 52 is fixedly connected to the output end of the drive motor 51. A spline groove 521 is opened on the outer wall of the drive shaft 52. Two first chucks 53 are symmetrically rotated and sleeved on the outer wall of the drive shaft 52. The two first chucks 53 are located at both ends of the spline groove 521. A third synchronous wheel 531 is fixedly connected to the side of the two first chucks 53 that is far away from each other.

[0037] Furthermore, the outer wall of the drive shaft 52 is provided with a spline groove 521. This design can effectively combine with other transmission components to ensure stable torque transmission and reduce energy loss. The two first chucks 53 are located at both ends of the spline groove 521 to ensure a balanced force distribution and make the transmission process smoother.

[0038] like Figure 3 and Figure 4 As shown, one of the third synchronous pulleys 531 is sleeved with the outer wall of the first synchronous pulley 24 and is connected to a first synchronous belt 241 for transmission. The other third synchronous pulley 531 is sleeved with the outer wall of the second synchronous pulley 32 and is connected to a second synchronous belt 33 for transmission. A bidirectional chuck 55 is slidably sleeved on the outer wall of the drive shaft 52 at the position of the spline groove 521. The bidirectional chuck 55 engages with the two first chucks 53 for transmission.

[0039] Furthermore, one of the third synchronous pulleys 531 is sleeved with the outer wall of the first synchronous pulley 24 and connected to a first synchronous belt 241 for transmission, ensuring effective linkage between the drive mechanism 5 and the main clamping mechanism 2, thereby improving overall work efficiency. The other third synchronous pulley 531 is sleeved with the outer wall of the second synchronous pulley 32 and connected to a second synchronous belt 33 for transmission, ensuring the synchronous operation of the auxiliary clamping mechanism 3. This design enables the main clamping mechanism 2 and the auxiliary clamping mechanism 3 to work in coordination according to a predetermined trajectory and speed, thereby improving overall clamping performance, reducing the risk of misalignment between different mechanisms, and ensuring the stability of the workpiece during processing. The bidirectional chuck 55 engages with the two first chucks 53 respectively, enabling bidirectional clamping during clamping, increasing the clamping force on the workpiece, and accelerating the operation response time.

[0040] like Figure 4 and Figure 5As shown, two sets of auxiliary frames 54 are symmetrically fixedly connected to the top of the workbench 1. Each set consists of two auxiliary frames 54. An electric push rod 541 is fixedly connected inside the two auxiliary frames 54. A chuck seat 56 is rotatably sleeved on the outer wall of the bidirectional chuck 55. A connecting rod 562 is symmetrically fixedly connected inside the chuck seat 56. The chuck seat 56 rotates and sleeves the bidirectional chuck 55 through the connecting rod 562. Two side ears 561 are symmetrically fixedly connected to the outer wall of the chuck seat 56. The telescopic end of the electric push rod 541 is fixedly connected to the outer wall of the side ears 561.

[0041] Furthermore, each pair of auxiliary frames 54 forms a group, which can effectively support the electric push rod 541, thereby realizing the efficient operation of the mechanical components. The design of the chuck 56 is to rotate and engage the bidirectional chuck 55 through the internal connecting rod 562. When the telescopic end of the electric push rod 541 is working, it can push the chuck 56, thereby achieving the purpose of driving the chuck 56 to move. At the same time, it can engage with the two first chucks 53 respectively to achieve the purpose of transmission.

[0042] This utility model provides a buffer rod welding and centering fixture. The specific working principle is as follows: During the buffer rod welding and centering process, the drive mechanism 5 plays a core driving and energy switching role. At the start of work, the buffer rod body 4 is placed on the top of the workbench 1. The main clamping mechanism 2 first starts to clamp one end of the buffer rod body 4. The drive motor 51 runs, and its output end drives the drive shaft 52 to rotate. At this time, the bidirectional chuck 55, which is slidably sleeved on the outer wall of the drive shaft 52 through the spline groove 521, is in a specific position and only meshes with one of the first chucks 53 for transmission. The first chuck 53... The three synchronous pulleys 531 drive the first synchronous pulley 24 in the main clamping mechanism 2 to rotate through the first synchronous belt 241, thereby causing the first threaded rod 23 to rotate. Since the two reciprocating frames 25 symmetrically threaded on the outer wall of the first threaded rod 23 are slidably connected to the guide rod 22, under the action of the threads, the two reciprocating frames 25 move towards each other along the guide rod 22. The connecting frame 26 slidably connected to the top of the reciprocating frame 25 moves accordingly, causing the clamping plate 27 fixedly connected to one side of the two connecting frames 26 to approach one end of the buffer rod body 4, thereby achieving the initial limiting clamping of one end of the buffer rod body 4.

[0043] Because the first threaded rod 23 has self-locking properties, after the main clamping mechanism 2 completes the clamping of one end of the buffer rod body 4, the drive mechanism 5 switches the kinetic energy. The electric push rods 541 fixed inside the two sets of auxiliary frames 54 symmetrically fixedly connected to the top of the worktable 1 move, driving the side ears 561 fixedly connected to the telescopic ends to move, thereby causing the card seat 56 fixedly connected to the side ears 561 to move. The bidirectional chuck 55, which is rotated and sleeved by the connecting rod 562 symmetrically fixedly connected inside the card seat 56, slides at the position of the spline groove 521 of the drive shaft 52 and engages with another first chuck 53 for transmission. At this time, the third synchronous wheel 531 on the first chuck 53 drives the second synchronous wheel 32 in the auxiliary clamping mechanism 3 to rotate through the second synchronous belt 33, thereby causing the second threaded rod 31 in the auxiliary clamping mechanism 3 to rotate. The two reciprocating frames 25 symmetrically threaded on their outer walls move towards each other along the guide rod 22, driving the clamping plate 27 to approach the other end of the buffer rod body 4, thereby realizing the secondary limiting clamping of the other end of the buffer rod body 4.

[0044] By controlling the kinetic energy switching between the main clamping mechanism 2 and the auxiliary clamping mechanism 3 through the drive mechanism 5, and considering that the two ends of the buffer rod body 4 have different dimensions, the main clamping mechanism 2 and the auxiliary clamping mechanism 3 clamp the buffer rod body 4 from both ends respectively, which can effectively increase the stability of the buffer rod body 4 during the processing. The main clamping mechanism 2 maintains the clamping state by utilizing the self-locking property of the first threaded rod 23, and the drive mechanism 5 can freely switch the kinetic energy to the auxiliary clamping mechanism 3 as needed to further clamp the buffer rod body 4, ensuring that the position of the buffer rod body 4 is stable throughout the entire processing process, and providing a strong guarantee for high-quality welding and alignment processing.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
