Description

Technical Field

[0001] This utility model relates to the field of clamping structure technology, specifically to an automatic alignment and welding fixture for ceramic heating elements. Background Technology

[0002] In the production process of ceramic heating elements, welding is a key process. Currently, companies often rely on clamps to fix two sections of ceramic heating elements before welding them together.

[0003] Existing fixtures have significant shortcomings in axial alignment, making it difficult to accurately align two components axially, resulting in low welding precision. This not only affects the performance and quality of ceramic heating elements but may also cause safety hazards. For example, misalignment of the welding points may lead to uneven heating of the components during use, thereby shortening the service life of the components and even causing malfunctions such as component breakage.

[0004] To address this, an automatic alignment and welding fixture for ceramic heating elements is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: An automatic alignment and welding fixture for ceramic heating elements includes a frame and a ceramic heating element body. A hydraulic rod is provided on the top surface of the frame, and a limit frame is fixedly installed at the end of the telescopic part of the hydraulic rod. Rotary seats are rotatably installed on the bottom surface of the frame and the limit frame, respectively. A rotary drive assembly is rotatably installed on the two sets of rotating seats and the frame to drive the two sets of rotating seats to rotate synchronously. A self-alignment clamping assembly is provided on the surface of the rotating seat for automatically positioning and clamping the ceramic heating element body.

[0007] Furthermore, the rotary drive assembly includes a first motor fixedly mounted on the top surface of the frame, and the output end of the first motor is fixedly connected to a rotating shaft through the top surface of the frame. A first synchronous pulley is fixedly sleeved on the rotating part of the two sets of rotating seats, a second synchronous pulley is sleeved on the surface of the rotating shaft, and a first synchronous belt is sleeved on the surface of the first synchronous pulley and the second synchronous pulley.

[0008] Furthermore, the first synchronous pulley, the second synchronous pulley, and the first synchronous belt located on the upper side are located within the limiting frame, and the second synchronous pulley is movably sleeved on the surface of the rotating shaft, while the second synchronous pulley located on the lower side is fixedly sleeved on the surface of the rotating shaft.

[0009] Furthermore, the inner wall of the upper second synchronous pulley is provided with two sets of protrusions, and the surface of the rotating shaft is provided with two sets of grooves. The protrusions on the inner wall of the upper second synchronous pulley are located in the grooves on the surface of the rotating shaft, so that the upper second synchronous pulley is driven to rotate by the grooves and protrusions through the rotation of the rotating shaft, and the upper second synchronous pulley slides axially on the surface of the rotating shaft.

[0010] Furthermore, the two sets of self-aligning clamping components are arranged vertically and coaxially, and the self-aligning clamping components include a U-shaped seat fixedly installed on the surface of the rotating seat.

[0018] like Figures 1 to 5As shown, an automatic alignment and welding fixture for ceramic heating elements includes a frame 1 and a ceramic heating element body 7. A hydraulic rod 2 is provided on the top surface of the frame 1, and a limit frame 3 is fixedly installed at the end of the telescopic portion of the hydraulic rod 2. Rotary seats 4 are rotatably mounted on the bottom surface of the frame 1 and the limit frame 3, respectively. A rotary drive assembly 5 is rotatably mounted on the frame 1 and on the two sets of rotating seats 4 to drive the two sets of rotating seats 4 to rotate synchronously. Figure 1 , Figure 2 , Figure 3 As shown, specifically, the rotary drive assembly 5 includes a first motor 501 fixedly mounted on the top surface of the frame 1, and the output end of the first motor 501 is fixedly connected to a rotating shaft 502 through the top surface of the frame 1. A first synchronous pulley 503 is fixedly sleeved on the rotating parts of the two sets of rotating seats 4. A second synchronous pulley 504 is sleeved on the surface of the rotating shaft 502. A first synchronous belt 505 is sleeved on the surfaces of the first synchronous pulley 503 and the second synchronous pulley 504. The first synchronous pulley 503, the second synchronous pulley 504, and the first synchronous belt 505 located on the upper side are positioned within a certain range. The second synchronous wheel 504 is movably sleeved on the surface of the rotating shaft 502 within the frame 3. The lower second synchronous wheel 504 is fixedly sleeved on the surface of the rotating shaft 502. The inner wall of the upper second synchronous wheel 504 is provided with two sets of protrusions. The surface of the rotating shaft 502 is provided with two sets of grooves. The protrusions on the inner wall of the upper second synchronous wheel 504 are located in the grooves on the surface of the rotating shaft 502. The upper second synchronous wheel 504 is driven to rotate by the rotation of the rotating shaft 502 through the grooves and protrusions. The upper second synchronous wheel 504 slides axially on the surface of the rotating shaft 502.

[0019] More specifically, when the first motor 501 operates, it drives the rotating shaft 502 to rotate. The rotating shaft 502 drives the two sets of second synchronous pulleys 504 to rotate. With the transmission action of the first synchronous belt 505, it drives the first synchronous pulley 503 to rotate synchronously, thereby realizing the synchronous rotation of the two sets of rotating seats 4. This synchronously drives the two ceramic heating element bodies 7 to rotate horizontally, ensuring that the welding operation between the two sets of ceramic heating element bodies 7 can be performed by the welding equipment. The first synchronous pulley 503, the second synchronous pulley 504, and the first synchronous belt 505 are located within the limiting frame 3, allowing the hydraulic rod 2 to be inserted. The telescopic movement enables the second synchronous wheel 504 to move axially along the surface of the rotating shaft 502, allowing ceramic heating element bodies 7 of different lengths to be connected and used. The upper second synchronous wheel 504 slides axially on the surface of the rotating shaft 502 and in the groove on its surface via the protrusion on its inner wall. This allows the second synchronous wheel 504 to move axially along the surface of the rotating shaft 502 via the telescopic movement of the hydraulic rod 2. At the same time, the rotating shaft 502 is rotatably inserted into the limiting frame 3. When the rotating shaft 502 rotates, the upper second synchronous wheel 504 is driven to rotate via the groove on the surface of the rotating shaft 502 and the protrusion on the inner wall of the second synchronous wheel 504.

[0020] The surface of the rotating base 4 is provided with a self-aligning clamping assembly 6 for automatically positioning and clamping the ceramic heating element body 7; such as Figure 3 and Figure 4 As shown, specifically, two sets of self-aligning clamping components 6 are arranged vertically and coaxially. The self-aligning clamping components 6 include a U-shaped seat 601 fixedly installed on the surface of the rotating seat 4. Two bidirectional threaded rods 602 are rotatably inserted into the two side walls of the U-shaped seat 601. A second motor 603 is fixedly installed on the inner wall of the U-shaped seat 601. A third synchronous wheel 604 is fixedly sleeved on the output end of the second motor 603 and the surface of the bidirectional threaded rod 602. A second synchronous belt 605 is sleeved on the surface of the two sets of third synchronous wheels 604. A movable side plate 606 is threadedly sleeved on the surface of the bidirectional threaded rod 602. The movable side plate 606 is slidably arranged in the through groove in the U-shaped seat 601. Clamping plates 607 are fixedly connected to the opposite surfaces of the movable side plates 606 by bolts. V-shaped openings are opened on the opposite surfaces of the two sets of clamping plates 607.

[0021] More specifically, the rotation of the second motor 603 drives the bidirectional threaded rod 602 to rotate via the third synchronous pulley 604 and the second synchronous belt 605. This causes the two sets of movable side plates 606 on its surface to move closer or further apart along its axial direction, thereby driving the movement of the two sets of V-shaped opening clamping plates 607. The V-shaped opening clamping plates 607 can better fit the outer surface of the ceramic heating element body 7, increasing the contact area and providing more stable radial support and clamping force. At the same time, they can also accommodate elements of different diameters. When the bidirectional threaded rod 602 rotates and drives the movable side plates 606 to move, the clamping plates 607 move accordingly. The V-shaped opening clamping plates 607 automatically adjust the clamping position of the ceramic heating element body 7 to achieve automatic centering clamping, thus enabling the coaxial fixation of the two sets of ceramic heating element bodies 7.

[0022] In summary: By fitting the end faces of the two ceramic heating element bodies 7 with the end faces of the self-aligning clamping assembly 6, the ceramic heating element bodies 7 are positioned within the self-aligning clamping assembly 6. The self-aligning clamping assembly 6 then automatically positions and clamps the ends of the ceramic heating element bodies 7. The extension of the telescopic part of the hydraulic rod 2 causes the welding ends of the ceramic heating element bodies 7 to fit together, achieving coaxial positioning and fixation of the two sets of ceramic heating element bodies 7. The rotation drive assembly 5 drives the two sets of rotating seats 4, the self-aligning clamping assembly 6, and the ceramic heating element bodies 7 to rotate synchronously, thereby enabling the ceramic heating element bodies 7 to rotate horizontally, assisting the welding personnel in welding the two sets of ceramic heating element bodies 7 using the welding equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
