Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine blade production equipment, and in particular to an automatic grinding machine for the root of the mold seam of wind turbine blades. Background Technology

[0002] Wind turbine blades are made by merging and bonding two prefabricated half-blades into a single blade. The joint between the two prefabricated half-blades (commonly known as PS and SS) to be merged and bonded is made by hand lay-up, which results in significant height differences. Before merging and bonding these two prefabricated half-blades, the higher part of the hand lay-up needs to be cut flat.

[0003] Currently, the industry mainly uses angle grinders for cutting, which is time-consuming, labor-intensive, and causes serious pollution, which is detrimental to workers' health and makes it difficult to control product quality. Utility Model Content

[0004] In order to solve the above-mentioned problems of the prior art, the present invention provides an automatic grinding machine for the root of the mold seam of wind turbine blades that can be hoisted, moved and installed on the flange edge that needs to be cut, and can automatically grind the higher part of the prefabricated half sheet on the hand lay-up.

[0005] To achieve the above objectives, an automatic grinding machine for the root of the mold joint of wind turbine blades is characterized by comprising:

[0006] The frame, from top to bottom, includes a crossbeam with lifting points, a pair of crossbeam legs, and a pair of leg supports suitable for welding and fixing to one side of the wind turbine blade mold. The crossbeam legs and the leg supports are connected by quick-connect clamps.

[0007] The grinding system is a three-axis linkage system comprising an X-axis unit, a Z-axis unit, a Y-axis unit, and an electrical control box. The X-axis unit is configured to be slidably mounted on a crossbeam laterally, and the Z-axis unit is configured to be slidably mounted on the X-axis unit vertically. The Y-axis unit includes a Y-axis frame configured to be slidably mounted on the Z-axis unit, a grinding motor mounted on the Y-axis frame via a motor mounting base, a grinding roller cover mounted below the grinding motor on the motor mounting base, a grinding roller mounted on the grinding roller cover via a grinding roller bearing, and a belt connecting the grinding motor and the grinding roller. The electrical control box is mounted on the X-axis unit.

[0008] In this invention, the automatic grinding machine for the root of the wind turbine blade mold seam is hoisted and moved by a crane via lifting points on the frame, and is lifted to the flange edge that needs to be cut. The split design of the frame allows the lower support leg to be welded to one side of the wind turbine blade mold. Therefore, when grinding is needed, the crane can be used to move the other parts of the automatic grinding machine for the root of the wind turbine blade mold seam above the support leg, and a quick clamp can be used to quickly connect the crossbeam support leg and the support leg. Through the aforementioned three-axis linkage structure of the grinding system, grinding can be successfully achieved, the structure is stable, and the movement of each axis is convenient.

[0009] Furthermore, the X-axis unit includes a pair of X-axis slide rails mounted on the crossbeam, an X-axis rack mounted on the crossbeam and located between the pair of X-axis slide rails, an X-axis bracket with an X-axis slider engaging with the X-axis slide rails, an X-axis drive mechanism mounted on the X-axis bracket, and a Z-axis bracket mounted on the X-axis bracket. The X-axis drive mechanism includes a reducer and an X-axis motor mounted on the reducer. The reducer is mounted on the X-axis bracket and has a drive gear meshing with the X-axis rack. The electrical control box is mounted on the X-axis bracket via an electrical control box bracket.

[0010] With the above structural configuration, the X-axis unit, driven by the X-axis motor and through the cooperation of gears and racks, can move efficiently and stably along the X-axis.

[0011] Furthermore, the Z-axis unit includes a Z-axis mounting bracket, a Z-axis slide, and a Z-axis motor. The Z-axis mounting bracket is fixed to the Z-axis support on one side and has a pair of Z-axis slide rails, a Z-axis lead screw located between the pair of Z-axis slide rails, and the aforementioned Z-axis motor that drives and connects to the Z-axis lead screw on the other side. The Z-axis slide has a pair of Z-axis sliders that are slidably connected to the pair of Z-axis slide rails and a Z-axis nut that is screwed to the Z-axis lead screw on one side.

[0012] With the above structural design, the Z-axis slide of the Z-axis unit can move efficiently and stably in the Z-axis direction under the drive of the Z-axis motor and through the cooperation of the lead screw and nut.

[0013] Furthermore, a pair of Y-axis slide rails, a Y-axis lead screw located between the pair of Y-axis slide rails, and a Y-axis motor driving the Y-axis lead screw are mounted on the other side of the Z-axis slide. In addition, a Y-axis slide is mounted on the Y-axis frame, and a pair of Y-axis sliders that are slidably connected to the pair of Y-axis slide rails and a Y-axis nut that is screwed to the Y-axis lead screw are mounted on the Y-axis slide.

[0014] With the above structural design, the Y-axis frame can move efficiently and stably in the Y-axis direction under the drive of the Y-axis motor through the cooperation of the lead screw and nut.

[0015] Furthermore, the polishing system also includes a vacuum cleaner, which is mounted on the X-axis bracket of the X-axis unit via a vacuum cleaner bracket. The Y-axis unit also includes a vacuum hood mounted on the polishing roller housing. The vacuum cleaner is connected to the vacuum hood via a vacuum hose. In addition, the polishing surface of the polishing roller is provided with S-shaped grooves.

[0016] With the above-mentioned structural design, the chips and dust discharged during the grinding process can be sucked into the vacuum cleaner at any time, which greatly improves the working environment and reduces environmental pollution; the S-shaped grooves on the grinding surface of the grinding roller greatly facilitate chip discharge while grinding, thus improving grinding efficiency.

[0017] Furthermore, it also includes a detachable twist lock for auxiliary connection of the crossbeam leg and the leg bracket. The bottom of the crossbeam leg has a base plate with an upper rectangular through hole, and the top of the leg bracket has a top plate with a lower rectangular through hole. The upper and lower rectangular through holes are aligned to form a rectangular through hole. The detachable twist lock is installed on the top plate of the leg bracket and includes a twist head with an irregular end that can be manually switched between a locked position and an unlocked position. In the locked position, the twist head passes through the rectangular through hole, and its irregular end is located above the base plate of the crossbeam leg and spans the rectangular through hole, thereby locking the crossbeam leg and the leg bracket together. In the unlocked position, the irregular end of the twist head faces the rectangular through hole, allowing the twist head to disengage from the base plate of the crossbeam leg to unlock the lock on the crossbeam leg and the leg bracket.

[0018] In this invention, the detachable twist lock adds an extra layer of security to the connection between the crossbeam leg and the leg bracket. Moreover, the detachable twist lock has a simple locking structure for the connection between the crossbeam leg and the leg bracket, and is easy to operate.

[0019] Furthermore, the detachable twist lock includes:

[0020] A fixed plate is provided with a pair of supporting columns, a pair of limiting blocks and an intermediate stop block located between the pair of limiting blocks, and the intermediate stop block and the pair of limiting blocks form a pair of handle limiting spaces;

[0021] A floating plate is located on a pair of support columns of a fixed plate and is fastened to the fixed plate by fixing bolts passing through the pair of support columns. The floating plate is provided with a central support column and a first central through hole passing through the central support column and the floating plate. A handle operation space is formed between the floating plate and the fixed plate.

[0022] The torsion head includes a torsion head cylindrical body that passes through the first central through hole and the aforementioned irregular end supported above the central support column, wherein the torsion head cylindrical body is fitted with a limit fastener at its position below the floating plate.

[0023] The handle is pivotally mounted on the cylindrical body of the toggle head below the limiting fastener. This allows the handle to rotate with the toggle head within the handle operating space to switch the irregular end of the toggle head between the locked and unlocked positions. On the other hand, it allows the handle to be limited within one of the handle limiting spaces in the locked and unlocked positions, respectively.

[0024] The fixed plate, through its aforementioned structural design, can be securely fastened to the floating plate, forming a handle operating space and a pair of handle limiting spaces. The structure of the floating plate, the toggle head, and the handle allows the irregularly shaped end of the toggle head to switch between locked and unlocked positions. The central support column on the floating plate and the upper limit fastener on the toggle head's cylindrical body below the floating plate limit the vertical position of the toggle head. The pivotable mounting structure of the handle relative to the toggle head's cylindrical body allows the handle to both rotate the toggle head and move in and out of the handle limiting spaces. The entire lock system uses no springs, gears, or other similar structures, making it simple, detachable, and easy to use.

[0025] Furthermore, the cylindrical body of the torsion head is provided with a washer mounting groove, in which a stop washer for a round nut is installed. The washer mounting groove is located above the limiting fastener, which is a round nut.

[0026] The above structural design prevents the torsion head from detaching from the floating plate.

[0027] Furthermore, the aforementioned irregular end of the twisting head has a cuboid locking part. When the irregular end is in the locked position, the cuboid locking part spans the rectangular through hole; when the irregular end is in the unlocked position, the cuboid locking part faces the rectangular through hole.

[0028] With the above structural arrangement, in the locked position, the irregular end is staggered relative to the rectangular through hole of the crossbeam leg and the leg bracket, so that it cannot be disengaged from the rectangular through hole; while in the unlocked position, the cuboid locking part is directly opposite the rectangular through hole, so that it can be disengaged from the rectangular through hole, that is, the crossbeam leg located above can be disengaged from the interference and locking of the irregular end.

[0029] Furthermore, the central support column of the floating plate is configured as a rectangular column that can pass through the rectangular through hole. When the irregular end is in the locked position, the cuboid locking part of the irregular end is cross-shaped with the rectangular column and thus offset by 90°; when the irregular end is in the unlocked position, the cuboid locking part is aligned with the rectangular column.

[0030] With the above structural design, the irregular end of the torsion head can be supported on the central support column of the floating plate in both the locked and unlocked positions. Furthermore, the central support column of the floating plate can enter the rectangular through hole of the crossbeam leg and the leg bracket to maintain support for the irregular end head at all times.

[0031] Furthermore, the cylindrical body of the toggle head has a round nut mounting part below the washer mounting groove. The outer circumference of the round nut mounting part is provided with external threads to cooperate with the limiting fastener. In addition, the cylindrical body of the toggle head has a handle bearing part below the round nut mounting part. The diameter of the handle bearing part is smaller than the diameter of the round nut mounting part.

[0032] The above structural design allows the limiting fastener to pass smoothly through the handle bearing part and be tightened onto the round nut mounting part.

[0033] Furthermore, the handle has a handle mounting portion with flat sides at one end. The handle bearing portion of the toggle head cylindrical body is provided with a longitudinally extending handle operating slot corresponding to the handle mounting portion. The handle mounting portion of the handle is mounted to the toggle head cylindrical body within the handle operating slot via a connecting bolt. Thus, the handle can drive the toggle head to rotate, and its handle mounting portion can pivot around the connecting bolt within the handle operating slot, thereby allowing the handle to pivot around the connecting bolt to move out of or into the handle limiting space on the fixed plate.

[0034] Furthermore, the floating plate is adapted to be detachably mounted below on the bottom surface of the top plate of the outrigger support via fastening bolts.

[0035] In the aforementioned locked position, the detachable twist lock is fixed to the top plate of the outrigger bracket via a floating plate, and through a rectangular through hole spanning the beam outrigger and outrigger bracket above via a special-shaped end, thereby locking the beam outrigger and outrigger bracket together.

[0036] Furthermore, a pair of support columns of the fixed plate are arranged at intervals and a pair of column center holes are provided on it. The fixing bolts are hexagonal socket head cap bolts with shoulder bolts. A pair of bolt fixing holes are provided on the floating plate accordingly. The fixing bolts pass through the column center holes from the bottom of the fixed plate and are fastened in the bolt fixing holes.

[0037] The above structural design allows the floating plate and the fixed plate to be fixedly connected together.

[0038] Furthermore, a second central through hole is provided on the fixing plate corresponding to the first central through hole. The second central through hole is configured to allow the twisted cylindrical body to pass through, and the second central through hole is located between a pair of supporting columns.

[0039] The installation of the twist head is made more convenient by the second center through hole on the fixing plate.

[0040] These and other aspects of the present invention will be more clearly illustrated by referring to the embodiments described below. Attached Figure Description

[0061] The specific embodiments of this utility model will now be described in conjunction with the accompanying drawings.

[0062] like Figures 1 to 8 As shown, an automatic grinding machine 100 for the root of the mold joint of a wind turbine blade according to a specific embodiment of the present invention includes a frame and a grinding system, wherein:

[0063] The frame, from top to bottom, includes a crossbeam 101 with a suspension point 111, a pair of crossbeam legs 1, and a pair of leg supports 2 suitable for welding and fixing to one side of the wind turbine blade mold 300. The crossbeam legs 1 and the leg supports 2 are connected by quick-connect clamps 3.

[0064] The grinding system is configured as a three-axis linkage system, including an X-axis unit 5, a Z-axis unit 6, a Y-axis unit 7, and an electrical control box 8. The X-axis unit 5 is slidably mounted laterally on a crossbeam 101. The Z-axis unit 6 is slidably mounted vertically on the X-axis unit 5. The Y-axis unit 7 includes a Y-axis frame 71 slidably mounted longitudinally on the Z-axis unit 6 and a grinding roller unit 70. The grinding roller unit 70 includes a grinding motor 73 mounted on the Y-axis frame 71 via a motor mounting base 72, a grinding roller housing 74 mounted below the grinding motor 73 on the motor mounting base 72, a grinding roller 76 mounted on the grinding roller housing 74 via a grinding roller bearing 75, and a belt (not shown in the figure, only a belt cover 77 and a synchronous pulley 78 for mounting the belt are shown). In this embodiment, the electrical control box 8 is mounted on the X-axis unit 5.

[0065] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the X-axis unit 5 includes a pair of X-axis slide rails 51 disposed on the crossbeam 101, an X-axis rack 53 disposed on the crossbeam 101 and located between the pair of X-axis slide rails 51, an X-axis bracket 55 with an X-axis slider 551 engaging with the X-axis slide rails 51, an X-axis drive mechanism mounted on the X-axis bracket 55, and a Z-axis bracket 58 mounted on the X-axis bracket 55. The X-axis drive mechanism includes a reducer 57 and an X-axis motor 59 mounted on the reducer 57. The reducer 57 is mounted on the X-axis bracket 55 and has a drive gear 573 meshing with the X-axis rack 53 (see...). Figure 3 The electrical control box 8 is mounted on the X-axis bracket 55 via the electrical control box bracket 80.

[0066] It should be noted that in this embodiment, the grinding surface of the grinding roller 76 is provided with an S-shaped groove (not shown in the figure). It should also be noted that in this embodiment, the lifting point 111 may not be directly disposed on the crossbeam 101, but may be directly mounted on the X-axis bracket 55, and then slidably mounted on the crossbeam 101 via the X-axis bracket 55, as shown below. Figure 1 and Figure 5 As shown.

[0067] like Figure 5 As shown, and refer to Figure 3In this embodiment, the Z-axis unit 6 includes a Z-axis mounting bracket 62, a Z-axis slide 64, and a Z-axis motor 66. The Z-axis mounting bracket 62 is fixed to a Z-axis support 58 on one side, and a pair of Z-axis slide rails 621, a Z-axis lead screw (not shown), and the aforementioned Z-axis motor 66 driving the Z-axis lead screw are arranged on the other side. The Z-axis slide 64 is equipped with a pair of Z-axis sliders 641 slidably connected to the pair of Z-axis slide rails 621, and a Z-axis nut 65 screwed to the Z-axis lead screw. Through this structural arrangement, the Z-axis slide 64 of the Z-axis unit 6 can move efficiently and stably along the Z-axis mounting bracket 62 under the drive of the Z-axis motor 66 and through the structural cooperation of the lead screw and nut.

[0068] For example Figure 5 As shown, and refer to Figure 3 In this embodiment, a pair of Y-axis slide rails 67, a Y-axis lead screw 68 located between the pair of Y-axis slide rails 67, and a Y-axis motor 69 driving the Y-axis lead screw 68 are mounted on the other side of the Z-axis slide 64. Furthermore, a Y-axis slide 79 is mounted on the Y-axis frame 71, and a pair of Y-axis sliders 797 slidably connected to the pair of Y-axis slide rails 67 and a Y-axis nut 799 screwed to the Y-axis lead screw 68 are mounted on the Y-axis slide 79. With this structural arrangement, under the drive of the Y-axis motor 69, the Y-axis unit 7 can move efficiently and stably in the Y-axis direction relative to the Z-axis slide 64 via the lead screw and nut structure.

[0069] like Figure 3 and Figure 4 As shown, in this embodiment, the grinding system also includes a vacuum cleaner 9, which is mounted on the X-axis bracket 55 of the X-axis unit 5 via a vacuum cleaner bracket 90. The Y-axis unit 7 also includes a dust collection cover 749 mounted on the grinding roller cover 74. The vacuum cleaner 9 is connected to the dust collection cover 749 via a vacuum hose (not shown). Through this structural arrangement, the chips and dust emitted during the grinding process can be sucked into the vacuum cleaner 9 at any time, greatly improving the working environment and reducing environmental pollution.

[0070] Compared with the traditional manual polishing production method, the core advantages of the above-mentioned structure of this utility model include: 1) Increased efficiency: 24-hour continuous operation, the speed can reach 3-5 times that of manual labor; 2) High consistency: eliminate human error and ensure stable quality of batch products; 3) Cost optimization: reduce reliance on manpower and reduce unit cost in the long term; 4) Safety: avoid the risk of workers being exposed to dust, noise and mechanical injury.

[0071] like Figures 9 to 19 As shown, and refer to Figure 1 and Figure 2As shown, in this embodiment, the connection between the crossbeam support leg 1 and the support leg bracket 2 of the automatic grinding machine 100 for the root of the wind turbine blade mold joint includes, in addition to the quick connection using a quick clamp 3, a detachable twist lock 4 for auxiliary connection of the crossbeam support leg 1 and the support leg bracket 2. Figures 16 to 19 As shown, the bottom of the crossbeam support leg 1 has a bottom plate 10 with an upper rectangular through hole, and the top of the support leg bracket 2 has a top plate 20 with a lower rectangular through hole. The upper and lower rectangular through holes are arranged opposite each other to form a rectangular through hole 12 (see...). Figure 17 and Figure 19 The detachable twist lock 4 is mounted on the top plate 20 of the outrigger bracket 2 and includes a locking position (see...). Figure 17 ) and unlock location (see Figure 19 The manually adjustable twist head 45, equipped with a shaped end 452, is positioned in the locked position. In this position, the twist head 45 passes through the rectangular through hole 12, with its shaped end 452 positioned above the base plate 10 of the crossbeam leg 1 and spanning the rectangular through hole 12, thereby locking the crossbeam leg 1 and the leg support 2 together. In the unlocked position, the shaped end 452 of the twist head 45 faces the rectangular through hole 12, allowing the twist head 45 to disengage from the base plate 10 of the crossbeam leg 1 to unlock the locking of the crossbeam leg 1 and the leg support 2. Specifically, in this embodiment, the twist head 45 disengages from the base plate 10 of the crossbeam leg 1 by moving the crossbeam leg 1 upwards, causing the base plate 10 of the crossbeam leg 1 to disengage from the twist head 45.

[0072] like Figure 10 and Figure 11 As shown, and refer to Figure 9 In this embodiment, the quick clamp 3 includes a clamp body 30 mounted on the top side of the support leg 2, a rotatable clamp 31 disposed on the clamp body 30, and a clamp hook 32 mounted on the bottom side of the crossbeam support leg 1 and cooperating with the rotatable clamp 31. After the crossbeam support leg 1 is placed on the support leg 2, the crossbeam support leg 1 and the support leg 2 can be quickly fixed together by rotating the rotatable clamp 31 and engaging it with the clamp hook 3. Since the quick clamp 3 is a standard part that can be purchased on the market and is not the focus of this invention, its specific structure will not be described in detail here.

[0073] like Figures 12 to 15 As shown, in this embodiment, the detachable twist lock 4 includes a fixed plate 41, a floating plate 43, a twist head 45, and a handle 47. The fixed plate 41 is provided with a pair of supporting columns 412, a pair of limiting blocks 414, and an intermediate stop block 416 located between the pair of limiting blocks 414. A pair of handle limiting spaces 415 are formed between the intermediate stop block 416 and the pair of limiting blocks 414.

[0074] The floating plate 43 is located on a pair of support columns 412 of the fixed plate 41 and is fastened to the fixed plate 41 by fixing bolts 42 passing through the pair of support columns 412. The floating plate 43 is provided with a central support column 432 and a first central through hole 430 passing through the central support column 432 and the floating plate 43. A handle operation space 44 is formed between the floating plate 43 and the fixed plate 41.

[0075] The twist head 45 includes a twist head cylindrical body 450 installed through the first central through hole 430 and an irregular end 452 supported above the central support column 432, wherein the twist head cylindrical body 450 is equipped with a limit fastener 46 at its position below the floating plate 43.

[0076] The handle 47 is pivotally mounted on the toggle head cylindrical body 450 below the limiting fastener 46, thereby enabling the handle to rotate with the toggle head 45 within the handle operating space 44, so as to achieve the locked position of the irregular end 452 (see Figure 12 , Figure 14 , Figure 16 and Figure 17 ) and unlock location (see Figure 15 , Figure 18 and Figure 19 On the one hand, the position conversion between the locked and unlocked positions allows the handle 47 to be limited within one of the handle limiting spaces 415 in both the locked and unlocked positions. Specifically, in this embodiment, the irregular end 452 is located within the left handle limiting space 415 in the locked position (e.g., Figure 12 As shown), the unlocked position is naturally within the right handle limiting space 415 (as shown). Figure 15 (As shown).

[0077] like Figure 13 , Figure 17 and Figure 19 As shown, a washer mounting groove 451 is provided on the cylindrical body 450 of the torsion head. A stop washer 461 for a round nut is installed in the washer mounting groove 451. The washer mounting groove 451 is located above the limiting fastener 46, which is a round nut.

[0078] like Figure 13 , Figure 14 As shown, the irregular end 452 has a cuboid locking part 4520. (As...) Figure 16 and Figure 17 As shown, when the irregular end 452 is in the locked position, the cuboid locking part 4520 spans the rectangular through hole 12 above the bottom plate 10 of the crossbeam leg 1, and is staggered relative to the rectangular through hole 12, so that it cannot disengage from the rectangular through hole 12, that is, the irregular end 452 interferes with the bottom plate 10 of the crossbeam leg 1; as Figure 18 and Figure 19 When the irregular end 452 is in the unlocked position, the cuboid locking part 4520 is directly opposite the rectangular through hole 12 formed on the crossbeam leg 1 and the leg bracket 2, so that it can disengage from the rectangular through hole 12. In other words, under this condition, the irregular end 452 no longer interferes with the crossbeam leg 1.

[0079] like Figures 13 to 14 As shown, in this embodiment, the central support column 432 of the floating plate 43 is configured as a rectangular column that can pass through the rectangular through hole 12. When the irregular end 452 is in the locked position, the cuboid locking part 4520 of the irregular end 452 intersects with the rectangular column-shaped central support column 432, thereby offsetting it by 90°. When the irregular end 452 is in the unlocked position, its cuboid locking part 4520 is aligned with the rectangular column-shaped central support column 432. With this structural arrangement, the irregular end 452 can be supported on the central support column 432 of the floating plate 43 in both the locked and unlocked positions.

[0080] It should be noted that, Figure 9 This illustration shows an application scenario of the detachable twist lock of this embodiment, which is applied to the crossbeam support leg 1 and support leg bracket 2 of the automatic grinding machine 100 for the root of the wind turbine blade mold joint. It is used to assist in connecting the crossbeam support leg 1 and support leg bracket 2 in addition to the quick-connect clamp 3. For example... Figure 16 and Figure 18 As shown, the detachable twist lock 4 is installed on the top plate 20 of the outrigger bracket 2. Specifically, the floating plate 43 of the detachable twist lock 4 is installed on the top plate 20 of the outrigger bracket 2 from below via fastening bolts (not shown). In the locked position, the central support column 432 of the floating plate 43 passes through the rectangular through hole 12, and the irregular end 452 supported on it is located above the bottom plate 10 of the crossbeam leg 1 and spans the rectangular through hole 12, thereby locking the crossbeam leg 1 and the outrigger bracket 2 together. In the unlocked position, the irregular end 452 is directly opposite the rectangular through hole 12, so that the irregular end 452 no longer interferes with the bottom plate 20 of the crossbeam leg 2, thereby unlocking the locking of the crossbeam leg 1 and the outrigger bracket 2. In other words, under these circumstances, the crossbeam leg 1 can move upward to disengage from the lock of the leg bracket 2, or the floating plate 43 of the detachable twist lock 4 can be removed from the top plate 20 of the leg bracket 2, and then the entire detachable twist lock 4 can disengage downward from the rectangular through hole 12, thereby unlocking the lock on the crossbeam leg 1 and the leg bracket 2.

[0081] like Figure 13As shown, in this embodiment, the toggle head cylindrical body 450 has a round nut mounting portion 456 below the washer mounting groove 451. The outer circumferential surface of the round nut mounting portion 456 is provided with an external thread to cooperate with the limiting fastener 46. Furthermore, the toggle head cylindrical body 450 has a handle bearing portion 457 below the round nut mounting portion 456. The diameter of the handle bearing portion 457 is smaller than the diameter of the round nut mounting portion 456, so that the limiting fastener 46 can pass smoothly through the handle bearing portion 457 and be tightened onto the round nut mounting portion 456.

[0082] For example Figure 13 As shown, in this embodiment, the handle 47 has a handle mounting portion 470 with both sides being flat at one end. The handle bearing portion 457 of the toggle head cylindrical body 450 is provided with a longitudinally extending handle operating slot 4570 corresponding to the handle mounting portion 470. The handle mounting portion 470 of the handle 47 is mounted on the toggle head cylindrical body 450 within the handle operating slot 4570 via a connecting bolt (not shown, but it passes through the bolt hole 475 on the handle 47 and the bolt hole 458 on the toggle head 45). Thus, the handle 47 can drive the toggle head 45 to rotate, and its handle mounting portion 470 can pivot around the connecting bolt within the handle operating slot 4570, thereby allowing the handle 47 to pivot around the connecting bolt to move out of or into the handle limiting space 415 on the fixing plate 41.

[0083] like Figure 17 and Figure 19 As shown, in this embodiment, the floating plate 43 is adapted to be detachably fixed to the bottom surface of the lower workpiece of a locked pair of workpieces. Specifically, the floating plate 43 is adapted to be fixed via a threaded hole 431 passing through it (see...). Figure 14 The fastening bolts (not shown) are detachably mounted on the top plate 20 of the leg bracket 2 below.

[0084] For example Figure 13 As shown, in this embodiment, a pair of support columns 412 of the fixed plate 41 are arranged at intervals and are provided with a pair of column center holes 4120 that pass through the pair of support columns 412. The fixing bolt 42 that connects the fixed plate 41 and the floating plate 43 is an internal hexagonal socket head cap bolt. A pair of bolt fixing holes 434 are provided on the floating plate 43. The fixing bolt 42 passes through the column center holes 4120 from the bottom of the fixed plate 41 and is fastened in the bolt fixing holes 434.

[0085] For example Figure 13As shown, in this embodiment, a second central through hole 410 is provided on the fixing plate 41 corresponding to the first central through hole 430. The second central through hole 410 is configured to allow the twist head cylindrical body 450 to pass through, and the second central through hole 410 is located between a pair of supporting columns 412. The provision of the second central through hole 410 makes the installation of the twist head 45 more convenient.
