Description

Technical Field

[0001] This invention belongs to the field of welding and processing technology for pre-embedded electrical conduits, and particularly relates to a welding fixture for pre-embedded electrical components in prefabricated buildings. Background Technology

[0002] In electrical installation engineering of prefabricated buildings, electrical pre-embedded sleeves are key components that ensure that pipelines meet the requirements of insulation, waterproofing, fireproofing and subsequent maintenance when passing through prefabricated building components (such as walls, floors and beams).

[0003] In the manufacturing and processing of electrical conduits, a key technological requirement exists: multiple wing rings must be welded equidistantly onto the conduit surface, ensuring that the wing rings remain coaxially fixed to the conduit while maintaining their perpendicularity. Currently, the traditional electrical conduit welding fixtures commonly used in the industry follow a fixed operating procedure when performing conduit welding and fixing: first, multiple wing rings are pre-fitted onto designated areas of the conduit, then the conduit with the wing rings fitted is placed onto the fixture. Next, the fixture must complete three core operations in stages: first, the conduit is positioned and clamped to ensure it does not shift during welding; second, the spacing between the wing rings is calibrated and fixed individually using the fixture's adjustment structure to ensure the spacing meets design standards; and third, the concentricity of the wing rings and the conduit is adjusted, while simultaneously verifying and ensuring that the wing rings remain perpendicular to prevent skewing.

[0004] However, this traditional clamping operation mode has obvious drawbacks: the entire process requires multiple stops and adjustments, the operation steps are cumbersome and require a high level of operator proficiency. Not only is it easy for human error to affect product accuracy, but more importantly, in batch processing scenarios, it will significantly extend the processing cycle of a single sleeve, seriously restricting the improvement of overall production efficiency.

[0005] Therefore, there is an urgent need for a prefabricated building electrical embedded component welding fixture to quickly and coaxially position the body of the electrical conduit and multiple wing rings at equal distances, so as to improve the welding processing efficiency of the electrical conduit.

The connecting blocks are fixedly connected to the lower side of the corresponding slide plate. Two guide rods that are symmetrical in left and right are also fixedly mounted on the upper side of the base. The guide rods are slidably connected to both slide plates. A motor is fixedly mounted on the front side of the base. The output shaft of the motor is fixedly connected to one end of the double-ended screw.

[0011] According to an advantageous embodiment, a sliding groove is provided on the upper side of the connecting seat, and the spacing adjustment component includes a double-headed screw three rotatably disposed in the sliding groove one. Two connecting blocks three that are symmetrical and have opposite thread directions are threadedly connected to the double-headed screw three, and the connecting blocks three are fixedly connected to the corresponding guide side plate.

[0012] According to an advantageous embodiment, the spacing adjustment assembly three includes a fixed seat one fixedly disposed on the side wall of the guide side plate, a sliding groove two provided on the fixed seat one, a one-way screw one rotatably disposed in the sliding groove two, a connecting block four threadedly connected to the one-way screw one, the connecting block four slidably connected to the sliding groove two, and a fixed seat two fixedly disposed on the connecting block four, a sliding groove three provided on the fixed seat two, a one-way screw two rotatably disposed in the sliding groove three, a sliding seat threadedly connected to the one-way screw two, the sliding seat slidably connected to the sliding groove three, and the sliding seat fixedly connected to the corresponding lifting block two.

[0013] According to an advantageous embodiment, guide rods three are fixedly provided on the side wall of the guide side plate on both the front and rear sides of the fixed seat one, and the fixed seat two is slidably connected to the corresponding guide rods three through a connecting plate.

[0014] According to an advantageous embodiment, the height adjustment assembly includes a rectangular column fixedly mounted on a connecting seat, with a one-way screw three threadedly connected to the upper end of the rectangular column.

In the present invention, through the coordinated action of clamping mechanism one and clamping mechanism two, the tube body of the pre-fitted wing ring only needs to be initially placed on the central protrusion of clamping mechanism one. Subsequently, by driving the sliding plate closer through the clamping sliding component, the horizontal guidance and vertical positioning of the wing ring, the equidistant adjustment of adjacent wing rings, the height lifting of the tube body and wing ring, and the front and rear centering of the tube body and wing ring can be completed simultaneously. There is no need to manually calibrate the wing ring spacing one by one or repeatedly adjust the concentricity, which can shorten the processing time of a single sleeve, thereby greatly shortening the cycle of electrical sleeves in mass production.

[0017] 2. In this invention, the sloping surfaces of the two symmetrical guide side plates form the feed guide ports. The two corresponding feed guide ports are close to each other and can automatically guide and clamp the wing rings to ensure the verticality of the wing rings and the spacing between adjacent wing rings.

[0018] 3. In this invention, when the two lifting blocks one and the two lifting blocks two are close to each other, they can simultaneously center the wing ring and the tube body and lift them to different predetermined heights, ensuring that the central axes of the tube body, wing ring and pressure plate are coincident and achieving strict coaxiality.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will now be described in further detail.

[0026] Please refer to the following: Figure 1A welding fixture for prefabricated building electrical embedded parts is disclosed, used to weld three wing rings 5 ​​onto a pipe body 4 to form an electrical conduit. The fixture includes a base 1, with clamping mechanisms 1 and 2 on both sides of the base 1 for fixing the two ends of the pipe body 4, and clamping mechanism 2 and 3 on the upper side of the base 1 for simultaneously positioning the sidewalls of the pipe body 4 and the sidewalls of the wing rings 5. The three wing rings 5 ​​are pre-fitted onto the pipe body 4, and then the pipe body 4 with the wing rings 5 ​​is placed on the clamping mechanism 1 and 2. The positions of the three wing rings 5 ​​are roughly adjusted so that they are aligned with the corresponding positions of the clamping mechanism 2 and 3. The clamping mechanism 2 and 3 first adjust the height of the pipe body 4 and the wing rings 5, as well as the horizontal and vertical positions of the wing rings 5. Then, the clamping mechanism 1 and 2 clamp and fix the pipe body 4, which has been raised to the predetermined position, in a centered manner. Then, it can be used with external welding equipment to weld the connection between the wing rings 5 ​​and the pipe body 4.

[0027] See Figures 1-3 The clamping mechanism 2 includes supports on the left and right sides of the base 1. An electric push rod 21 is fixedly installed on the support. The telescopic end of the electric push rod 21 passes through the support and is fixedly connected to a motor 22. The output shaft of the motor 22 is fixedly connected to a pressure plate 23. A central protrusion 24 is fixedly installed on the opposite sides of the two pressure plates 23.

[0028] In actual operation, the two ends of the tube body 4 are respectively fitted onto the surface of the central protrusion 24 at the center position of the corresponding pressure plate 23 to provide initial support for the tube body 4. Subsequently, after the tube body 4 and the wing ring 5 are positioned by the clamping mechanism 2 3, the two pressure plates 23 are driven by their respective electric push rods 21 to push the tube body 4 to the center, so that the pressure plate 23 and the ends of the tube body 4 are pressed together. During the welding process, the pressure plate 23 can be driven by the motor 1 22 to rotate the tube body 4, and the connection between the wing ring 5 and the tube body 4 can be completely welded.

[0029] See Figures 1-5The clamping mechanism 2 3 includes two sliding plates 31 slidably mounted on the upper side of the base 1 and symmetrically arranged front and back via a clamping sliding assembly 32. Three connecting seats 33 are arranged on the sliding plates 31 along their length direction. The left and right connecting seats 33 on the same sliding plate 31 are slidably mounted on the sliding plate 31 via a spacing adjustment assembly 1 34. A triangular lifting block 1 35 is fixedly arranged on the opposite side of the two corresponding connecting seats 33. Two left and right symmetrical guide side plates 37 are slidably mounted on the upper side of the connecting seats 33 via a spacing adjustment assembly 2 36. The side of the two adjacent guide side plates 37 away from the sliding plate 31 is set as a ramp surface. The side of the two corresponding guide side plates 37 away from each other is slidably mounted with a triangular lifting block 2 39 via a spacing adjustment assembly 38. The side of the two corresponding connecting seats 33 away from each other is mounted with a spring telescopic baffle 311 via a height adjustment assembly 310. The sloping surfaces of two adjacent guide side plates 37 form a feed guide port. The initial position of the wing ring 5 is between the feed guide ports formed by the two guide side plates 37 on one side. When the two sets of guide side plates 37 on the front and rear sides of the wing ring 5 move toward the wing ring 5 at the same time, the two feed guide ports move closer to each other and guide the front and rear sides of the wing ring 5. Finally, the wing ring 5 moves relative to the pipe body 4 and clamps the wing ring 5 between the four guide side plates 37, ensuring that the wing ring 5 is vertically in the designated position.

[0030] In specific operation, in order to quickly position the three wing rings 5 ​​on the tube body 4, the front and rear slide plates 31 are driven to move closer to each other by the clamping sliding assembly 32, thereby causing the connecting seat 33 on the front and rear slide plates 31 to move towards the side wall of the tube body 4.

[0031] First, the sloping surfaces of two adjacent guide side plates 37 form a feed guide port. The initial position of the wing ring 5 is between the feed guide ports formed by the two guide side plates 37 on one side. When the two sets of guide side plates 37 on the front and rear sides of the wing ring 5 move towards the wing ring 5 simultaneously under the drive of the corresponding connecting seat 33, the two feed guide ports on the front and rear sides of the wing ring 5 approach each other to guide the front and rear sides of the wing ring 5. Finally, the wing ring 5 moves relative to the tube body 4 and is clamped between the four guide side plates 37, ensuring that the wing ring 5 is vertically in the specified position and that the distance between adjacent wing rings 5 ​​remains unchanged.

[0032] The connecting seat 33 will also cause the corresponding lifting blocks 35 to move closer to each other. After the wing ring 5 is guided by the guide side plate 37, the two corresponding lifting blocks 35 and the two corresponding lifting blocks 39 continue to move closer to each other.

[0033] The two corresponding lifting blocks 35 together abut against the front and rear outer walls of the wing ring 5, which has been vertically limited. Since the lifting blocks 35 are triangular, when the two corresponding lifting blocks 35 approach each other, the ramp surface of the lifting blocks 35 can gradually push the corresponding wing ring 5 upward to a certain height. At this time, the upper half of the front and rear outer walls of the wing ring 5 abuts against the corresponding spring telescopic baffle 311, improving the stability of the wing ring 5 during the initial welding. Moreover, the ramp surfaces of the two corresponding lifting blocks 35 together form a V-shaped lower support surface, allowing the wing ring 5 to rise to the predetermined height while being centered in the front-rear direction.

[0034] When the wing ring 5 is centered, the two corresponding lifting blocks 39 at the front and rear can simultaneously move closer to each other to center the tube body 4 in the same way and lift it to a certain height. This allows the tube body 4 and the wing ring 5 to be centered and lifted to the corresponding height at the same time, so that the central axis of the tube body 4 coincides with the central axis of the wing ring 5 and the central axis of the pressure plate 23, making the wing ring 5 coaxially fitted on the surface of the tube body 4. The lower part of the outer peripheral wall of the wing ring 5 is supported by the lifting block 35, while its left and right sides are limited by the guide side plates 37. The lower part of the outer peripheral wall of the tube body 4 is supported by the lifting block 39. Then, the two pressure plates 23 on the left and right sides of the tube body 4 can move closer to each other, pushing the tube body 4 to be centered and aligned in the left and right directions. At this time, the three wing rings 5 ​​remain vertical and coaxial with the tube body 4, and the three wing rings 5 ​​are evenly distributed at a predetermined distance.

[0035] See Figure 3 The sliding clamp assembly 32 includes a double-ended screw 321 rotatably mounted on a base 1 via two lugs. Two symmetrical connecting blocks 322 with opposite thread directions are threaded onto the double-ended screw 321. The connecting blocks 322 are fixedly connected to the lower side of their respective slide plates 31. Two symmetrical guide rods are also fixedly mounted on the upper side of the base 1, slidably connected to both slide plates 31. A motor is fixedly mounted on the front side of the base 1, with its output shaft fixedly connected to one end of the double-ended screw 321. The motor drives the double-ended screw 321 to rotate, causing the two connecting blocks 322 to move closer together, which in turn causes the corresponding connecting seats 33 on the two slide plates 31 to move closer together.

[0036] See Figure 1 , Figure 3 and Figure 4To meet the different welding spacing requirements of adjacent wing rings 5, the spacing adjustment component 34 includes a double-headed screw 341 rotatably mounted on the upper side of the slide plate 31 via two left and right lugs 341. A connecting block 342 is fixedly mounted on the lower side of the connecting seat 33. The left and right connecting blocks 342 are threadedly connected to the corresponding double-headed screw 341 in opposite directions. The double-headed screw 341 movably passes through the middle connecting block 342. The left and right connecting blocks 342 are slidably connected to the corresponding slide plate 31, and the middle connecting block 342 is fixedly connected to the corresponding slide plate 31. A guide rod 2 is also fixedly mounted on the slide plate 31, and the guide rod 2 is slidably connected to all the connecting blocks 342 on the same slide plate 31. The operator can rotate the double-headed screw 341 to move the left and right connecting blocks 342 relative to the middle connecting block 342, adjusting the distance between the left and right connecting seats 33 and the middle connecting seat 33, thereby adjusting the distance between the left and right adjacent lifting blocks 35 and the distance between the left and right adjacent sets of guide side plates 37.

[0037] See Figure 4 and Figure 5 To meet the guiding requirements of wing rings 5 ​​of different thicknesses, a groove is provided on the upper side of the connecting seat 33. The spacing adjustment component 36 includes a double-ended screw 361 rotatably disposed in the groove. Two connecting blocks 362, symmetrically arranged with opposite thread directions, are threaded onto the double-ended screw 361. The connecting blocks 362 are fixedly connected to the corresponding guide side plates 37. The operator can rotate the double-ended screw 361, so that the two connecting blocks 362 can drive their respective guide side plates 37 to move, controlling the left and right corresponding guide side plates 37 to move closer or further apart, adjusting the spacing between two adjacent guide side plates 37 to meet the guiding and positioning requirements of wing rings 5 ​​of different thicknesses.

[0038] See Figures 3-5 To meet the lifting height requirements of pipe bodies 4 and wing rings 5 ​​with different diameters, the spacing adjustment assembly 38 includes a fixed seat 381 fixedly mounted on the side wall of the guide side plate 37. The fixed seat 381 has a sliding groove 2. A one-way screw 382 is rotatably mounted in the sliding groove 2. A connecting block 383 is threadedly connected to the one-way screw 382. The connecting block 383 is slidably connected to the sliding groove 2. A fixed seat 384 is fixedly mounted on the connecting block 383. The fixed seat 384 has a sliding groove 3. A one-way screw 385 is rotatably mounted in the sliding groove 3. A slide block 386 is threadedly connected to the one-way screw 385. The slide block 386 is slidably connected to the sliding groove 3. The slide block 386 is fixedly connected to the corresponding lifting block 39. By controlling the rotation of one-way screw 382 and one-way screw 385, the height of lifting block 39 can be adjusted, and the initial distance between the two corresponding lifting blocks 39 can also be adjusted.

[0039] See Figure 4 and Figure 5 Guide rods three are fixedly installed on the side wall of the guide side plate 37 on both the front and rear sides of the fixed seat 381. The fixed seat 384 is slidably connected to the corresponding guide rods three through a connecting plate. The guide rods three further connect the fixed seat 384 to the corresponding guide side plate 37, improving the stability of the fixed seat 384 when it drives the lifting block 39 to lift the tube body 4.

[0040] See Figure 4 and Figure 5 To facilitate limiting the movement of wing rings 5 ​​of different diameters, the height adjustment assembly 310 includes a rectangular column 3101 fixedly mounted on the connecting seat 33. A one-way screw 3102 is threadedly connected to the upper end of the rectangular column 3101. The one-way screw 3102 is rotatably connected to a spring telescopic baffle 311, and a limit stop 3103 is slidably inserted between the spring telescopic baffle 311 and the rectangular column 3101. The spring telescopic baffle 311 includes a plate body 1 rotatably connected to the one-way screw 3102, and a plate body 2 slidably inserted onto the plate body 1. Spring telescopic rods are provided on both the front and rear sides of the plate body 2 and the plate body 1. The operator controls the one-way screw 3102 to rotate relative to the rectangular column 3101 and the spring telescopic baffle 311, thereby moving the spring telescopic baffle 311 upwards and adjusting its height.

[0041] It should be noted that for each model of tube body 4 and wing ring 5, technicians will repeatedly experiment and adjust the spacing between adjacent guide side plates 37, the initial spacing between the corresponding front and rear lifting blocks 39, and the height difference between the corresponding lifting blocks 35 and lifting blocks 39 to ensure that tube body 4 and wing ring 5 can be accurately positioned.

[0042] Meanwhile, regarding the use of spacing adjustment components 1 (34), 2 (36), and 3 (38) in this solution during actual welding, the lifting block 1 (35), lifting block 2 (39), and guide side plate 37 only need to be adjusted according to the welding requirements of the batch of electrical bushings before processing all electrical bushings for a single batch. No repeated adjustments are required after the initial adjustment. During the actual welding process, the entire fixture only needs to move the clamping sliding component 32 to complete the clamping and positioning between the pipe body 4 and the multiple wing rings 5.

[0043] Compared to traditional clamps that require three separate steps to complete "clamping the tube body 4 → calibrating the spacing of the wing rings 5 ​​→ adjusting concentricity and verticality", with each step requiring pauses and adjustments, resulting in a fragmented operation process, this clamp achieves integrated operation of "synchronous positioning of the tube body 4 and wing rings 5" through the coordinated action of clamping mechanism 1 2 and clamping mechanism 2 3. Simply place the tube body 4 with the pre-fitted wing rings 5 ​​on the central protrusion 24 of clamping mechanism 1 2, and then drive the sliding plate 31 to move closer via the clamping sliding component 32. This simultaneously completes the horizontal guidance and vertical positioning of the wing rings 5, the equidistant adjustment of adjacent wing rings 5, the height increase of the tube body 4 and wing rings 5, and the front-to-back centering of the tube body 4 and wing rings 5, eliminating the need for manual calibration of the wing ring spacing or repeated adjustments to concentricity. This fixture significantly shortens the processing cycle of a single sleeve, and in mass production scenarios, it can significantly improve overall production efficiency. Meanwhile, the clamping sliding assembly 32, spacing adjustment assembly one 34, spacing adjustment assembly two 36, spacing adjustment assembly 38, and height adjustment assembly 310 in this solution are all composed of conventional ordinary mechanical parts, without using any high-cost precision mechanical parts. Only a one-time investment is required for long-term use; therefore, the cost of adding these structures is low, and compared to the efficiency improvement brought by welding large quantities of electrical sleeves, the cost of adding these structures is negligible. In summary, the above-mentioned technical solution of this invention is a specific improvement based entirely on the existing technology and aimed at solving the technical problems described above.
