Description

Technical Field

[0001] This invention relates to the field of curtain wall installation technology, specifically to a positioning device for curtain wall installation. Background Technology

[0002] The installation process of a curtain wall can be roughly divided into three stages: the embedded parts stage, the keel installation stage, and the panel installation stage. Among them, the keel installation stage is the core link of the curtain wall project. By connecting the keel with the embedded parts, a rigid network is formed to ensure the stability and precision of the structure.

[0003] During the keel installation phase, it is necessary to first install adapters on the embedded parts, and then connect the vertical keels to the adapters using bolts. Therefore, the installation and positioning of the adapters on the embedded parts is crucial, directly affecting the structural safety, installation accuracy, and subsequent maintenance performance of the entire curtain wall system. It can be said that the accurate positioning of the adapters is the "benchmark starting point" for the installation of the curtain wall keels and even the panels. Accumulated deviations will lead to serious problems such as subsequent keel twisting, misalignment of panels, sealing failure, and even poor load transfer.

[0004] In actual construction, the positioning of the adapter components presents the following problems: First, the fixing process requires the use of laser line projectors and laser plumb bobs to locate the adapter components, and temporary fixation is achieved through manual support and spot welding. After verification, a full weld is then performed between the adapter component and the embedded part. However, if the verification fails (i.e., the adapter component's position is incorrect), the original weld points must be removed using an angle grinder to ensure complete separation of the adapter component from the embedded part. This process is then repeated after repositioning. This not only increases the number of steps, labor, and material costs, but the repeated grinding and secondary welding also reduces the material's mechanical properties, creating safety hazards for the subsequently installed keel support. Second, the verification stage still relies on laser line projectors and laser plumb bobs, making it difficult to directly verify the position between adjacent adapter components. This may lead to errors during actual installation, resulting in error accumulation. Summary of the Invention

[0005] The purpose of this invention is to provide a positioning device for curtain wall installation, so as to solve at least one technical problem existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for curtain wall installation, comprising: a positioning block and an installation assembly capable of assembling the positioning block onto the mounting surface of an embedded plate, wherein the positioning block has two parallel magnetic reference surfaces on both sides, and the magnetic reference surfaces provide a reference contact surface for the adapter; a three-dimensional adjustment assembly disposed between the positioning block and the installation assembly, wherein the positioning block can be angled in three-dimensional space through the three-dimensional adjustment assembly; a positioning part disposed at the top of the positioning block and a calibration part disposed at the bottom of the positioning block, wherein the positioning part can emit two mutually perpendicular laser reference lines, and the bottom surface of the calibration part has a cross-shaped landing surface, and the landing surface has two states: first, a planar state in which the landing surface is flush with the bottom surface of the calibration part, and in the planar state, the laser reference lines can be directly projected onto the landing surface; second, a recessed state in which the landing surface is retracted into the calibration part, and in the recessed state, the laser reference lines need to pass through the cross groove before projecting onto the landing surface.

[0007] Optionally, the positioning part includes four recessed holes and at least two laser emitting pens formed on the top of the positioning block. The four recessed holes are arranged in a cross shape, and each laser emitting pen can be detachably installed in the recessed hole.

[0008] Optionally, the calibration unit includes a bottom frame fixedly installed at the bottom of the positioning block. The bottom of the bottom frame has an inner cavity, and multiple first barcode plates and multiple second barcode plates are slidably installed in the inner cavity.

The first barcode plates and the second barcode plates are connected to the inner wall of the inner cavity by springs. Adjacent first barcode plates are slidably connected to each other, and adjacent second barcode plates are slidably connected to each other.

[0009] Optionally, both the first and second barcode plates have arc-shaped grooves on their bottom surfaces.

[0010] Optionally, the positioning block consists of a first housing and a second housing assembled together. The three-dimensional adjustment assembly includes a fixing ring fixed on the mounting assembly. A bearing seat is rotatably mounted inside the fixing ring. A horizontal shaft is rotatably mounted on the side of the bearing seat away from the fixing ring. A vertical shaft is rotatably mounted on the outer wall of the horizontal shaft. The horizontal shaft passes through the vertical shaft and forms a cross shape with the vertical shaft. The outer wall of the second housing has a through-hole groove. The outer wall of the first housing has two holes that can extend into the holes. The two ends of the vertical shaft are rotatably mounted in the two holes, respectively.

[0011] Optionally, a first locking rod is threaded into the first screw hole on the outer wall of the fixing ring, and the first locking rod can abut against the shaft seat. A third screw hole is provided on the outer wall of the first housing, and a third locking rod is threaded into the third screw hole. The end of the third locking rod extends into the mating groove and abuts against the vertical shaft. A T-shaped hole is provided inside the shaft seat. A top rod is slidably installed on the vertical section of the T-shaped hole. The horizontal section of the T-shaped hole is set as a second screw hole, and a second locking rod is threaded into the second screw hole. The contact end between the second locking rod and the top rod is set as a conical end.

[0012] Optionally, both ends of the vertical shaft are provided with telescopic pins that can elastically extend and retract.

[0013] Optionally, the positioning block is provided with limiting parts on both sides, and the two limiting parts can move closer or further apart from each other.

The two ends of the second bidirectional screw pass through the two claws respectively and are threadedly connected to the through-hole of the two claws. The outer wall of the support plate is provided as a magnetic suction surface.

[0014] Optionally, at least two insertion rods are fixed on the side of the limiting part near the first housing. The side wall of the first housing has insertion holes for the insertion rods to pass through and slide. The outer wall of the first housing also has threaded holes. An adjusting bolt is rotatably installed inside the first housing, and the adjusting bolt is threadedly engaged with the threaded holes.

[0015] Optionally, the mounting assembly includes an I-shaped component with guide rods fixed on both the upper and lower sides. A clamping plate is slidably mounted on the outer wall of the guide rod. Scales are provided on both outer walls of the I-shaped component and the side walls of the clamping plate. A first bidirectional screw is rotatably mounted inside the middle vertical rod of the I-shaped component. The two ends of the first bidirectional screw pass through the two clamping plates respectively and are threadedly connected to the through-holes of the clamping plates.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] I. This invention provides a pre-fixed plane for the adapter by using the magnetic reference surfaces on both sides of the positioning block. It utilizes the cooperation of the laser reference line and the crosshair landing point to achieve precise three-dimensional positioning, allowing the adapter to be directly fully welded after magnetic attachment, eliminating the need for the repetitive steps of "temporary spot welding → inspection → adjustment → re-spot welding" in traditional construction. Simultaneously, the positioning block effectively fills and positions the vertical keel between the two adapters, ensuring the surface contact accuracy between the adapter and the subsequent keel installation. This avoids positioning deviations caused by thermal deformation from multiple welding operations, improving the installation efficiency and positioning accuracy of the adapter.

[0018] Second, this invention only requires absolute positioning of the first positioning block. Subsequent positioning blocks are then calibrated in a chain-like manner through the laser reference line and the calibration section of the previous positioning block. Multi-point positioning along the Y-axis is completed sequentially using the relative positional relationship between adjacent positioning blocks. This calibration method transforms complex absolute spatial positioning into simple relative position retesting. Operators only need to observe the landing point of the laser spot on the barcode board to determine the direction of deviation, and fine-tune the angle in the XZ, XY, and YZ planes using a three-dimensional adjustment component. No professional measuring instruments or complex calculations are required, significantly reducing the technical skill requirements for operators and minimizing accumulated errors during the reference transfer process.

[0019] Third, the installation assembly of this invention adopts an I-beam design, which not only enables quick clamping and fixing of the positioning block and the embedded plate, but also physically separates the welding area of ​​the adapter, containing welding slag and reducing spatter contamination. More importantly, the contact surface between the I-beam and the embedded plate can be designed with a heat-conducting layer and heat dissipation fins. During the welding process, a heat-conducting layer is formed between the weld point and the chemical anchor, effectively blocking and dispersing the transfer of welding heat to the chemical anchor position, avoiding the deterioration of the mechanical properties of the chemical anchor due to high temperature, and thus ensuring the long-term reliability of the connection between the embedded part and the main structure.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 2This invention provides a technical solution: a positioning device for curtain wall installation, comprising: a positioning block 2 and an installation component 1 capable of assembling the positioning block 2 onto the mounting surface of the embedded plate 7. The positioning block 2 has two parallel magnetic reference surfaces on both sides, and the magnetic reference surfaces provide a reference contact surface for the adapter 8. A three-dimensional adjustment component 6 is provided between the positioning block 2 and the installation component 1, and the positioning block 2 can be adjusted in three-dimensional space through the three-dimensional adjustment component 6. The top of the positioning block 2 is provided with a positioning part 5 and the bottom is provided with a calibration part 4. The positioning part 5 can emit two mutually perpendicular laser reference lines. The bottom surface of the calibration part 4 is provided with a cross-shaped landing surface, and the landing surface has two states: first, a planar state where the landing surface is flush with the bottom surface of the calibration part 4, and in the planar state, the laser reference line can be directly projected onto the landing surface; second, a recessed state where the landing surface is retracted into the calibration part 4, and in the recessed state, the laser reference line needs to pass through the cross groove before projecting onto the landing surface.

[0037] When using this positioning device, the positioning block 2 first needs to be assembled onto the mounting surface of the embedded plate 7 using the mounting component 1. The parallel magnetic reference surfaces on both sides of the positioning block 2 provide a pre-fixed plane for the adapter 8. Currently, most adapters 8 commonly used in the market are L-shaped, and their installation state is as follows: Figure 13 and 14 As shown, where Figure 13 This demonstrates the contact state between the plane of adapter 8 and the plane of embedded plate 7, while Figure 14 The display shows the L-shaped end face of the adapter 8 in contact with the plane of the embedded plate 7. The similarity between the two installation states is that after the adapter 8 is fixed, it is in surface contact with the vertical keel, and then it is installed by bolt fixing. Therefore, the design of the positioning block 2 is equivalent to filling the vertical keel between the two adapters 8 in the positioning stage, and also provides a foundation for the subsequent positioning work.

[0038] During positioning, the positioning blocks 2 are installed sequentially on the vertically embedded plate 7, such as... Figure 1 As shown, the first positioning block 2 is then positioned spatially using existing external equipment such as laser line projectors and laser plumb lines. This can be achieved using existing methods, such as aligning the edge line of the positioning block 2 with the laser line projector's line, or measuring the distance between it and the wall or embedded plate 7 using tools like a square. Simultaneously, the three-dimensional adjustment component 6 is used to adjust the position of the positioning block 2 until it is calibrated in its spatial state. Once the first positioning block 2 is positioned, subsequent positioning blocks 2 can be positioned using the first positioning block 2 as a reference, rather than being positioned individually. The specific positioning method is as follows:

[0039] To facilitate the subsequent description of directions and planes, the horizontal direction is set as the X-axis, the vertical direction as the Y-axis, and the direction perpendicular to the embedded plate 7 as the Z-axis.

[0040] Two mutually perpendicular laser reference lines are projected upwards from the positioning part 5 of the lower curtain wall installation positioning device and illuminated on the cross-shaped landing surface of the calibration part 4 of the upper curtain wall installation positioning device. The cross-shaped landing surface can be a complete cross-shaped landing surface or a landing surface in the X and Y axes arranged in a cross shape, i.e., an incomplete cross-shaped landing surface. Both states are acceptable. The landing surface is initially planar, i.e., the landing surface is flush with the bottom surface of the calibration part 4, so that the laser reference lines can fall on the calibration part 4. Subsequently, the positioning block 2 is angularly adjusted in the XZ plane by the three-dimensional adjustment component 6 so that the laser reference lines coincide with the landing surface.

[0041] Subsequently, the landing surface switches to a concave state. In this concave state, the landing surface retracts into the calibration section 4 to form a cross-shaped groove. Similarly, this cross-shaped groove can be a cross-shaped groove, or it can be an incomplete cross-shaped groove where the extended lines of the arc grooves 46 in the X and Y axes are arranged in a cross shape. In this case, the mutually perpendicular laser reference lines need to pass through the grooves in the X and Z axes respectively before landing on the landing surface. Figure 7 As shown, L represents the path of the laser beam. A laser beam of path L can completely pass through the groove and illuminate the landing surface. This means that the laser beam has no angular deviation in the YZ plane, and therefore the landing point of the laser beam can completely fall on the landing surface. However, if part of the laser beam of path L falls on the inner wall of the groove, that is... Figure 8 If the laser beam cannot completely land on the landing surface at position N, then the three-dimensional adjustment component 6 is needed to adjust the angle of positioning block 2 in the XY plane and YZ plane until the laser beams in the X-axis and Y-axis directions can completely land on the landing surface. At this point, the positioning of the second positioning block 2 is completed, as is the positioning of the magnetic reference surfaces on both sides of positioning block 2. Then, the third positioning block 2 is positioned with the second positioning block 2 as the reference, and so on, to complete the positioning of positioning block 2 in the Y-axis direction. Then, the adapter 8 is magnetically attracted to the magnetic reference surface, and its edge line is kept coincident or parallel with the edge line of the magnetic reference surface to complete the positioning of the adapter 8 and the keel contact surface. Then, the adapter 8 is moved along the Z-axis direction to make it fit with the embedded plate 7, and then full welding can be performed directly.

[0042] In this way, the positioning of the adapter 8 can be achieved by positioning the positioning block 2. Moreover, by using the calibration positioning between adjacent positioning blocks 2, only the first positioning block 2 needs to be positioned, and then the subsequent positioning blocks 2 can be calibrated in sequence. After the adapter 8 is magnetically attracted to the magnetic reference surface on both sides of the positioning block 2, it can be fully welded. There is no need to perform spot welding and repeated inspection. This reduces the number of procedures while ensuring the positioning accuracy of the adapter 8, thereby ensuring the accuracy of the subsequent vertical keel installation.

[0043] The positioning part 5 includes four recessed holes 51 and at least two laser emitting pens 52 on the top of the positioning block 2. The four recessed holes 51 are arranged in a cross shape, and each laser emitting pen 52 can be detachably installed in the recessed hole 51.

[0044] like Figure 2 and Figure 4 The laser lines are formed by emitting laser lines using laser emitting pens 52. There are two ways to do this. First, two laser emitting pens 52 can emit two laser lines that are perpendicular to each other. The two laser emitting pens 52 need to be inserted into two adjacent recesses 51 respectively. In this way, the laser lines emitted by the two laser emitting pens 52 can project a cross laser line at the bottom of the upper calibration part 4, thereby achieving the above-mentioned calibration and positioning purpose. The specific state is not shown in the figure. However, this method requires calibration of the perpendicularity of the laser projection lines emitted by the two laser emitting pens 52 after they are inserted, which is more troublesome. It is necessary to directly fix the laser emitting pens 52 to ensure that the laser projection lines emitted by the two are perpendicular.

[0045] Therefore, the second method, which is more preferred, is adopted in this case. That is, two laser emitting pens 52 emit a laser beam respectively, and the two laser emitting pens 52 are inserted into two corresponding recesses 51 respectively. In this way, the laser beams emitted by the two laser emitting pens 52 will project two light spots at the bottom of the calibration part 4 above, and the line connecting the two light spots can determine a horizontal line. Similarly, when the two laser emitting pens 52 are installed in the other two corresponding recesses 51, the line connecting the two light spots can determine another horizontal line, so the effect of cross-shaped projection can also be achieved, and the above-mentioned calibration and positioning purpose can also be achieved. Alternatively, four laser emitting pens 52 can be installed directly to form four light spots. In this case, two laser emitting pens 52 will be used as an example for description.

[0046] To match the light spots emitted by the laser pointer 52 and to determine whether the line connecting the two light spots lies on the crosshair landing surface of the calibration unit 4, multiple sets of crosshair landing surfaces are designed, such as... Figure 3 , Figure 5 and Figure 6As shown, the calibration unit 4 includes a bottom frame 41 fixedly installed at the bottom of the positioning block 2. The bottom of the bottom frame 41 has an inner cavity 42, and multiple first barcode plates 43 and multiple second barcode plates 44 are slidably installed in the inner cavity 42. The first barcode plates 43 and the second barcode plates 44 are vertically distributed, and the intersection of the two adopts a U-shaped design. The first barcode plates 43 and the second barcode plates 44 are connected to the inner wall of the inner cavity 42 by springs 45. Adjacent first barcode plates 43 are slidably connected to each other, and adjacent second barcode plates 44 are slidably connected to each other.

[0047] First, the mutually perpendicular first barcode plate 43 and second barcode plate 44 form the cross-shaped landing surface. However, due to the design of multiple barcode plates, there will be many sets of positions for the cross-shaped landing surface. Figure 3 For example, position a is the spot of the laser pointer 52. In a planar state, when the two spot points are on the same second barcode plate 44, it can be determined that the positioning block 2 is accurate in the XZ plane. Conversely, when the two spot points are not on the same second barcode plate 44, it is necessary to rotate and adjust in the XZ plane until the spot points are on the same second barcode plate 44, thus completing the positioning of the positioning block 2 in the XZ plane.

[0048] After positioning, press the second barcode plate 44 back, causing it to compress the spring 45 and form a recessed groove with the side wall of the surrounding second barcode plate 44, switching to the recessed state, as shown. Figure 7 As shown, the light spot will extend further as the second barcode plate 44 is pressed back. If the light spot still falls on the second barcode plate 44, then it can be determined that the positioning block 2 is accurate in the XY plane. If the light spot falls on the inner wall of the recessed groove, that is... Figure 8 If the position is as shown in the diagram (N), then rotational adjustment is needed in the XY plane. Simultaneously, the position of positioning block 2 in the X-axis direction must also be adjusted until the light spot falls completely on the pressed-back second barcode plate 44, and the light spot must fall on the center of the second barcode plate 44. Figure 3 As shown, the positioning block 2 can be positioned on the XY plane.

[0049] Similarly, when the two laser pointers 52 are inserted into the other two slots 51, the two light spots will fall on the first barcode plate 43, as shown. Figure 3The operation of the light spot shown in b is the same as described above. In the planar state, the positioning of the positioning block 2 on the XZ plane can be determined by observing whether the two light spot landing points are located on the same first barcode plate 43. This is also a retest of the XZ plane positioning. The difference is that when the first barcode plate 43 is pressed back and switched to the recessed state, whether the light spot landing point can completely fall on the pressed-back first barcode plate 43 reflects the accuracy of the positioning block 2 on the YZ plane. If it falls on the side wall of the recessed groove, the angle of the positioning block 2 on the YZ plane needs to be adjusted until the light spot landing point can completely fall on the pressed-back first barcode plate 43. However, there is another difference from the second barcode plate 44: the final light spot landing point does not necessarily have to fall on the middle first barcode plate 43. Figure 3 As shown in b, because the long slot on the adapter 8 allows the vertical keel and the adapter 8 to have a certain offset in the Z-axis direction, the two light spot landing points only need to be able to fall on the same first barcode plate 43, without needing to be calibrated further.

[0050] In this way, by calibrating on the three planes XZ, XY and YZ, the spatial positioning of the subsequent positioning block 2 can be completed, and thus the positioning of the adapter 8 can also be completed.

[0051] To enable operators to better observe the position of the light spot, arc-shaped grooves 46 are provided on the bottom surfaces of both the first barcode plate 43 and the second barcode plate 44. Figure 6 As shown, the arc-shaped groove 46 can make the light spot more concentrated, making it easier to observe whether it falls completely.

[0052] Moreover, it is worth mentioning that since the distance between adjacent positioning blocks 2 (i.e. adjacent embedded plates 7) is relatively large, if the positioning block 2 has an error in the XY plane, the degree of error will be amplified as the distance increases. As reflected in the spot landing point, after the second barcode plate 44 switches to the recessed state, the spot landing point will fall on the side wall of the recessed groove, which makes it easier for the operator to observe. Conversely, when the spot landing point can pass through the recessed groove and fall completely within the arc groove 46, the accuracy of the positioning block 2 will be higher.

[0053] To facilitate easy adjustment of positioning block 2 in the X-axis direction, see... Figure 2 and Figure 4 The mounting assembly 1 includes an I-shaped component 11, with guide rods 12 fixed on both the upper and lower sides of the I-shaped component 11. A clamping plate 13 is slidably mounted on the outer wall of the guide rod 12. Scales are provided on both outer walls of the I-shaped component 11 and the side walls of the clamping plate 13. A first bidirectional screw 14 is rotatably mounted inside the middle vertical rod of the I-shaped component 11. The two ends of the first bidirectional screw 14 pass through the two clamping plates 13 respectively and are threadedly connected to the through points of the clamping plates 13.

[0054] During the installation phase, the I-beam 11 is attached to the outer wall of the embedded plate 7. By rotating the first bidirectional screw 14, the two clamping plates 13 are brought closer together by the threaded engagement, clamping and fixing the upper and lower sides of the embedded plate 7, so that the positioning block 2 can be assembled on the embedded plate 7. At the same time, the position of the positioning block 2 on the embedded plate 7 along the X-axis can be observed through the scale on both sides of the I-beam 11. The clamping plates 13 can be loosened and adjusted in the X-axis direction until the above-mentioned spot can fall on the second barcode plate 44 located in the middle.

[0055] Furthermore, the I-beam 11 can physically separate the welding area of ​​the adapter 8 on the embedded plate 7, which can also contain the welding slag during the subsequent welding process and reduce its splashing to the surrounding area. At the same time, a heat-conducting layer can be designed on the contact surface between the I-beam 11 and the embedded plate 7, and heat dissipation fins (not shown in the figure) can also be added to the I-beam 11. In this way, during the subsequent welding process, the I-beam 11 can form a heat-conducting layer between the weld point and the chemical anchor of the embedded plate 7, further reducing the amount of heat transferred to the chemical anchor position, thereby avoiding any impact on the performance of the chemical anchor.

[0056] In a further preferred embodiment, to make the rotation adjustment of the positioning block 2 more consistent, the adjustment position of the three-dimensional adjustment component 6 is designed to be at the center of the positioning block 2, such as... Figure 9 - Figure 12 As shown, the positioning block 2 is firstly composed of a first housing 21 and a second housing 22 that are assembled together, and the contact surfaces of the first housing 21 and the second housing 22 are provided with slots. The bottom frame 41 is connected by a top-formed connecting block 47. Figure 5 As shown, the bottom frame 41 is fastened between the first housing 21 and the second housing 22 to facilitate disassembly and installation. The three-dimensional adjustment component 6 includes a fixing ring 61 fixed on the mounting component 1. A bearing seat 62 is rotatably installed inside the fixing ring 61. A horizontal shaft 63 is rotatably installed on the side of the bearing seat 62 away from the fixing ring 61. A vertical shaft 64 is rotatably installed on the outer wall of the horizontal shaft 63, and the horizontal shaft 63 passes through the vertical shaft 64 and forms a cross shape with the vertical shaft 64. The outer wall of the second housing 22 has a through-hole groove 65. The outer wall of the first housing 21 is fixed with two hole seats 66 that can extend into the hole groove 65. The two ends of the vertical shaft 64 are rotatably installed in the two hole seats 66 respectively.

[0057] The vertical axis 64 is located on the vertical center line of the Y-axis of the positioning block 2, while the horizontal axis 63 is located on the horizontal center line of the X-axis of the positioning block 2, and the bearing seat 62 is located on the horizontal center line of the Z-axis. When the positioning block 2 is rotated in the XY plane, it rotates around the bearing seat 62 as the axis. When the positioning block 2 is rotated in the XZ plane, it rotates around the vertical axis 64 as the axis. When the positioning block 2 is rotated in the YZ plane, it rotates around the horizontal axis 63 as the axis.

[0058] To ensure that the rotational adjustments of the three surfaces do not interfere with each other, it is necessary to fix the bearing 62, the horizontal axis 63, and the vertical axis 64, as follows: Figure 9-11 As shown, a first locking rod 611 is threaded into the first screw hole on the outer wall of the fixing ring 61, and the first locking rod 611 can abut against the bearing seat 62. A third screw hole is provided on the outer wall of the first housing 21, and a third locking rod 641 is threaded into the third screw hole. The end of the third locking rod 641 extends into the mating groove 65 and can abut against the vertical shaft 64. A T-shaped hole 634 is provided inside the bearing seat 62. A top rod 632 is slidably installed on the vertical section of the T-shaped hole 634. The horizontal section of the T-shaped hole 634 is set as a second screw hole, and a second locking rod 631 is threaded into the second screw hole. The contact end between the second locking rod 631 and the top rod 632 is set as a conical end 633.

[0059] The rotational locking of the shaft seat 62 is achieved by rotating the first locking rod 611 to press and fix it. The vertical shaft 64 is locked in the same way, by rotating the third locking rod 641 inside the first housing 21. The horizontal shaft 63 is locked as follows: Figure 11 As shown, by rotating the second locking rod 631, the cone end 633 at its end is used to press the top rod 632, and the top rod 632 is used to press and lock the horizontal shaft 63.

[0060] In this way, by locking each of them independently, the adjustment of positioning blocks 2 on different surfaces can be made independent of each other until they are fully positioned, at which point they can all be locked.

[0061] Both ends of the vertical shaft 64 are equipped with telescopic pins 67 that can elastically extend and retract, such as... Figure 12 As shown, the design of the telescopic pin 67 facilitates its installation with the inner hole seat 66 of the first housing 21.

[0062] In a further preferred embodiment, to accommodate vertical keels of different widths, the magnetic reference surfaces on both sides of the positioning block 2 are made adjustable, such as... Figure 3 and Figure 4 As shown, the positioning block 2 has limiting parts 3 on both sides, and the two limiting parts 3 can move closer or further apart. Each limiting part 3 includes a support plate 31 and grippers 32 slidably mounted on both sides of the support plate 31. A second bidirectional screw 33 is rotatably mounted inside the support plate 31. Both ends of the second bidirectional screw 33 pass through the two grippers 32 and are threadedly connected to the penetration points of the two grippers 32. The outer wall of the support plate 31 is provided as a magnetic surface. The magnetic surface can be achieved by embedding a fixed magnetic strip on the outer wall of the support plate 31, such as... Figure 4 As shown.

[0063] Among them, at least two insertion rods 34 are fixed on the side of the limiting part 3 near the first housing 21. The side wall of the first housing 21 is provided with insertion holes 36 for the insertion rods 34 to pass through and slide. The outer wall of the first housing 21 is also provided with threaded holes 37. An adjusting bolt 35 is rotatably installed inside the first housing 21. The adjusting bolt 35 can be screwed into the threaded hole 37 and threadedly engaged with the threaded hole 37.

[0064] After positioning and fixing the positioning block 2, insert the insertion rod 34 of the limiting part 3 into the insertion hole 36 on the side wall of the first housing 21, and screw the adjusting bolt 35 into the threaded hole 37. By turning the adjusting bolt 35, the distance between the limiting part 3 and the positioning block 2 can be adjusted, thereby adjusting the spacing between the two adapters 8 (according to the width of the keel). At the same time, the adjusting bolt 35 is embedded in the limiting part 3, such as... Figure 4 As shown, this is to avoid affecting the installation of adapter 8.

[0065] After adjustment, the adapter 8 is magnetically attached to the outer wall of the support plate 31. By rotating the second bidirectional screw 33, the two clamps 32 are brought closer together by the threaded engagement, and the edge of the adapter 8 is limited and positioned. Then, the adapter 8 is pushed towards the embedded plate 7 until the two contact. The clamps 32 are then further clamped and fixed. Then, depending on the degree of contact between the adapter 8 and the embedded plate 7, it is determined whether to directly weld the adapter 8 or add a shim before welding. This completes the positioning of the adapter 8 and the subsequent welding process.

[0066] After welding is completed, the positioning device can be completely removed from the embedded plate 7.

[0067] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0068] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
