Description

Technical Field

[0001] This invention relates to the field of clamping equipment technology, and in particular to a clamping fixture for a locking hook reinforcing plate assembly. Background Technology

[0002] In recent years, with the rapid development of my country's economy and automotive industry, people's demands for automobile quality, performance, and a sleek, beautiful, and dynamic body design have been increasing. The performance requirements for the hood have also risen. The hood lock hook reinforcement assembly, located between the inner and outer panels of the hood, is primarily used for welding the lock hook to itself and then to the inner hood panel, ensuring a stable and reliable connection between the hood and the vehicle body.

[0003] The automotive hood latch reinforcement plate assembly includes the hood latch reinforcement plate assembly and the latches.

[0039] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] The following is for reference. Figures 1-9 The fixture 100 of the lock hook reinforcing plate assembly 200 according to an embodiment of the present invention is described. The lock hook reinforcing plate assembly 200 includes a lock hook 8 and a reinforcing plate 7 welded together. The reinforcing plate 7 includes a first plate surface and a second plate surface opposite to each other. The lock hook 8 is welded to the second plate surface.

[0041] In the existing technology, the welding length between the lock hook and the reinforcing plate is too long, and the welding requires full welding, which causes the reinforcing plate to undergo severe deformation after welding, and cannot meet the quality requirements of the lock hook reinforcing plate assembly.

[0042] The fixture 100 of this invention is used to clamp the reinforcing plate 7 and the locking hook 8, so that the locking hook 8 and the reinforcing plate 7 can be welded together to form the locking hook reinforcing plate assembly 200. The fixture 100 of this invention fixes and limits the reinforcing plate 7 and the locking hook 8, which can reduce the deformation of the reinforcing plate 7 during welding and improve the product quality of the locking hook reinforcing plate assembly 200.

[0043] The fixture 100 includes: a base 1, a positioning component 2, a plate clamping pair 3, and a locking hook clamping component 4. The base 1 is the base of the fixture 100. The positioning component 2, the plate clamping pair 3, and the locking hook clamping component 4 are all located on the base 1. The base 1 serves to support and fix the fixture.

[0044] The positioning component 2 is used to position the reinforcing plate 7 so that it can be clamped and fixed later. It can be understood that the locking hook 8 is welded to the reinforcing plate 7. Therefore, positioning the reinforcing plate 7 by the positioning component 2 also facilitates the subsequent clamping and fixing of the locking hook 8, so that the position between the locking hook 8 and the reinforcing plate 7 can be fixed before welding.

[0045] The plate clamping pair 3 is used to clamp and fix the positioned reinforcing plate 7. Each plate clamping pair 3 includes a pressing block 31 and a supporting block 32 arranged opposite each other. The supporting block 32 is used to press against the first plate surface, and the pressing block 31 is used to press against the second plate surface. The pressing block 31 and the supporting block 32 together apply pressure to the reinforcing plate 7 to clamp and fix the reinforcing plate 7. After the positioning assembly 2 positions the reinforcing plate 7, the plate clamping pair 3 clamps and fixes the reinforcing plate 7, and the reinforcing plate 7 is fixed and limited.

[0046] like Figure 1 and Figure 3 As shown, the clamping block 31 is located above the support block 32, and the clamping block 31 and the support block 32 are directly opposite each other in the vertical direction. When the plate clamping pair 3 clamps and fixes the reinforcing plate 7, the first plate surface of the reinforcing plate 7 is located below, and the second plate surface is located above. The support block 32 is used to press against the first plate surface, and the clamping block 31 is used to press against the second plate surface. The vertical direction here is based on the orientation shown in the accompanying drawings. This is only for the convenience of describing the invention and simplifying the description, and is not intended to indicate or imply that the plate clamping pair 3 has a specific orientation, or is constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the invention.

[0047] The plate clamping pairs 3 include multiple pairs, which are suitable for being arranged at multiple corners of the reinforcing plate 7. The plate clamping pairs 3 clamp and fix the corners of the reinforcing plate 7, which not only fixes and limits the reinforcing plate 7, but also reduces the amount of deformation of the reinforcing plate 7 during welding. At least two plate clamping pairs 3 are arranged at at least one corner to form over-constraint on the corners of the reinforcing plate 7. The plate clamping pairs 3 not only clamp and fix the corners of the reinforcing plate 7, but also clamp and fix the adjacent parts of the corners, such as the edges of the reinforcing plate 7, further reducing the amount of deformation of the reinforcing plate 7 during welding and improving the product quality of the locking hook reinforcing plate assembly 200.

[0048] By setting multiple plate clamping pairs 3, the reinforcing plate 7 is subjected to uniform force, which can firmly fix the reinforcing plate 7. In addition, the multiple plate clamping pairs 3 form over-constraint on the edges and corners of the reinforcing plate 7, which can reduce the amount of deformation of the reinforcing plate 7 during welding and improve the product quality of the locking hook reinforcing plate assembly 200.

[0049] Optionally, multiple plate clamping pairs 3 are arranged at each corner of the reinforcing plate 7, with two plate clamping pairs 3 arranged at each corner to form over-constraint on the corner of the reinforcing plate 7, ensuring uniform stress on the reinforcing plate 7 and reducing the deformation of the reinforcing plate 7 during welding. Alternatively, at least one corner is provided with three plate clamping pairs, which not only fix the corner of the reinforcing plate 7 but also fix the two sides forming the corner, further securing the reinforcing plate 7.

[0050] The hook clamping assembly 4 is used to clamp the hook 8. After the positioning assembly 2 positions the reinforcing plate 7, the hook clamping assembly 4 keeps the hook 8 and the reinforcing plate 7 relatively fixed, so that the hook 8 and the reinforcing plate 7 can be welded together to form the hook reinforcing plate assembly 200. Alternatively, after the plate clamping pair 3 clamps and fixes the reinforcing plate 7, the hook clamping assembly 4 keeps the hook 8 and the reinforcing plate 7 relatively fixed, so that the hook 8 and the reinforcing plate 7 can be welded together to form the hook reinforcing plate assembly 200. By setting the hook clamping assembly 4, the hook 8 and the reinforcing plate 7 can be kept relatively fixed, the hook 8 and the reinforcing plate 7 can be accurately positioned, which facilitates the welding of the hook 8 and the reinforcing plate 7, avoids the positional displacement of the hook 8, and improves the product quality of the hook reinforcing plate assembly 200.

[0051] According to an embodiment of the present invention, the fixture 100 clamps and fixes the positioned reinforcing plate 7 by setting multiple plate clamping pairs 3. The reinforcing plate 7 is subjected to uniform force, which can firmly fix the reinforcing plate 7. In addition, the multiple plate clamping pairs 3 form over-constraint on the edges and corners of the reinforcing plate 7, which can reduce the deformation of the reinforcing plate 7 during welding and improve the product quality of the locking hook reinforcing plate assembly 200. Furthermore, by setting the locking hook clamping assembly 4, the locking hook 8 and the reinforcing plate 7 are kept relatively fixed, which improves the working stability of the welding process and improves the product quality of the locking hook reinforcing plate assembly 200.

[0052] like Figure 1 and Figure 4 As shown, the locking hook 8 includes a locking ring section 81 and a connecting section 82 connecting the locking ring section 81. The connecting section 82 is used for welding and connecting the reinforcing plate 7. There are two connecting sections 82, which are respectively connected to the two ends of the locking ring section 81. Each connecting section 82 is welded with two sections of carbon dioxide shielded welding. The connecting section 82 is fully welded continuously to the reinforcing plate 7 along its length. The surface must be free of pores and impurities.

[0053] like Figure 4 As shown, the second plate surface of the reinforcing plate 7 is recessed towards the first plate surface to form a hook groove 71. The hook 8 is disposed in the hook groove 71 and welded to the reinforcing plate 7. By setting the hook groove 71, the hook 8 can be pre-positioned, ensuring accurate and uniform welding positions between the hook 8 and the reinforcing plate 7, thus improving the product quality of the hook reinforcing plate assembly 200. The hook clamping assembly 4 is used to clamp the hook 8, positioning it within the hook groove 71 and keeping the hook 8 relatively fixed to the reinforcing plate 7, so that the hook 8 and the reinforcing plate 7 are welded together to form the hook reinforcing plate assembly 200.

[0054] like Figure 4 As shown, the connecting section 82 is set in the locking hook groove 71 to pre-position the locking hook 8, and the connecting section 82 is used to weld the reinforcing plate 7. There are two connecting sections 82, and correspondingly, there are also two locking hook grooves 71.

[0055] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the lock hook clamping assembly 4 includes two shaped blocks 41 located on opposite sides of the lock ring section 81. The two shaped blocks 41 are arranged in a direction parallel to the reinforcing plate 7. The shaped blocks 41 on both sides form shaped grooves 411, which are used to cover the two ends of the lock ring section 81.

[0056] The two shaped blocks 41 work together to apply pressure to the locking hook 8, clamping and fixing it in place, thus keeping the locking hook 8 relatively fixed to the reinforcing plate 7. A shaped groove 411 is formed on the shaped block 41, which covers both ends of the locking ring section 81. By providing the shaped groove 411, the contact area between the shaped block 41 and the locking hook 8 can be increased, thereby improving the clamping stability of the shaped block 41 on the locking hook 8.

[0057] In some embodiments, such as Figure 4 As shown, the locking ring segment 81 comprises three cylindrical segments connected in sequence: a first locking ring segment 811, a second locking ring segment 812, and a third locking ring segment 813. All three segments are constructed as cylindrical sections. The shaped groove 411 is a semi-circular groove with a diameter greater than or equal to the diameter of the cylindrical segment. The shaped groove 411 can enclose the locking ring segment 81, improving the clamping stability of the shaped block 41 on the locking hook 8.

[0058] In some specific embodiments of the present invention, such as Figure 4 and Figure 5 As shown, when the reinforcing plate 7 is placed horizontally, the first plate surface of the reinforcing plate 7 is located at the bottom, and the second plate surface is located at the top. The connecting section 82 of the locking hook 8 is used for welding connection to the second plate surface. The connecting section 82 extends horizontally, and the first locking ring section 811 and the third locking ring section 813 connected to the connecting section 82 extend in the vertical direction, and the first locking ring section 811 and the third locking ring section 813 are spaced apart in the horizontal direction.

[0059] Symbol block 41 consists of two elements, such as... Figure 5 As shown, the first symbol block 41a and the second symbol block 41b are both located above the reinforcing plate 7 and are spaced apart in the left-right direction. The first symbol block 41a is used to cooperate with the first locking ring segment 811, and the second symbol block 41b is used to cooperate with the third locking ring segment 813. The first symbol block 41a applies pressure to the first locking ring segment 811 from left to right, and the second symbol block 41b applies pressure to the third locking ring segment 813 from right to left. The first symbol block 41a and the second symbol block 41b together apply inward pressure to the locking hook 8 to clamp and fix the locking hook 8. The first symbol block 41a and the second symbol block 41b are directly opposite each other in the horizontal direction, and the directions applied to the locking ring are opposite and directly opposite to improve the clamping stability of the symbol block 41 on the locking hook 8.

[0060] The right side wall of the first symbol block 41a has a symbol groove 411, and the left side wall of the second symbol block 41b has a symbol groove 411. The symbol groove 411 extends in the vertical direction in the same direction as the first locking ring segment 811 and the third locking ring segment 813. The symbol groove 411 can cover the locking ring segment 81, thereby improving the clamping stability of the symbol block 41 on the locking hook 8.

[0061] In some embodiments of the present invention, such as Figure 3 As shown, the lock hook clamping assembly 4 also includes a lock hook positioning member 42 located between the two shaped blocks 41. The lock ring segment 81 includes three cylindrical segments connected in sequence. The two shaped blocks 41 respectively cooperate with the two outer segments of the lock ring segment 81, and the lock hook positioning member 42 cooperates with the middle segment of the lock ring segment 81. The lock hook positioning member 42 forms a lock hook 8 positioning groove on the side facing the reinforcing plate 7, and the middle part of the lock ring segment 81 is locked in the lock hook 8 positioning groove.

[0062] In some specific embodiments of the present invention, such as Figure 4 and Figure 5As shown, when the reinforcing plate 7 is placed horizontally, the first and second shaped blocks 41a and 41b are both located above the reinforcing plate 7. The locking hook positioning member 42 is located between the two shaped blocks 41a and also above the reinforcing plate 7. The locking hook positioning member 42 is used to cooperate with the second locking ring segment 812. The first and third locking ring segments 811 and 813 are spaced apart in the left-right direction. The second locking ring segment 812 connects the first and third locking ring segments 811 and extends in the left-right direction. The bottom wall of the locking hook positioning member 42 is provided with a locking hook 8 positioning groove, which also extends in the left-right direction. The locking hook 8 positioning groove locks the second locking ring segment 812 and limits the locking hook 8 in the up-down direction.

[0063] In some embodiments, the second locking ring segment 812 is also constructed as a cylindrical segment, the positioning groove of the locking hook 8 is a semi-circular groove, and the diameter of the positioning groove of the locking hook 8 is greater than or equal to the diameter of the second locking ring segment 812. The positioning groove of the locking hook 8 can cover the second locking ring segment 812, which can increase the contact area between the locking hook positioning member 42 and the locking hook 8, and improve the clamping stability of the locking hook 8 by the shaped block 41.

[0064] Understandably, the reinforcing plate 7 is placed horizontally, and the locking hook 8 is located above the reinforcing plate 7 and positioned within the locking hook groove 71, which pre-positions the locking hook 8. Two shaped blocks 41 press the locking hook 8 inwards, limiting its horizontal position. The locking hook positioning component 42 presses the locking hook 8 against the reinforcing plate 7 from top to bottom, thus limiting its vertical position. The locking hook clamping assembly 4 positions the locking hook 8 within the locking hook groove 71, maintaining its relative fixation to the reinforcing plate 7, improving the stability of the welding process, and enhancing the product quality of the locking hook reinforcing plate assembly 200.

[0065] In some embodiments, at least one of the shaped block 41 and the hook positioning member 42 is movable relative to the hook 8. During the process of the hook 8 being placed in the hook groove 71, the shaped block 41 and the hook positioning member 42 can avoid the movement path of the hook 8, thus avoiding interference with the hook 8 and facilitating the use of the fixture 100. After the hook 8 is placed in the hook groove 71, the shaped block 41 and the hook positioning member 42 are moved to fix the hook 8, making it convenient to use. After the hook 8 and the reinforcing plate 7 are welded to form the hook reinforcing plate assembly 200, the shaped block 41 and the hook positioning member 42 can move relative to the hook reinforcing plate assembly 200 to release the restriction on the hook reinforcing plate assembly 200, making it convenient to remove the hook reinforcing plate assembly 200 from the fixture 100.

[0066] In some embodiments of the present invention, such as Figure 3 and Figure 5As shown, the locking hook clamping assembly 4 also includes two rotating arms 43, which are rotatably connected to the base 1, and each of the two rotating arms 43 is connected to a symbol block 41 at one end adjacent to the other.

[0067] Positioning component 2 and plate clamping pair 3 are mounted on base 1. After positioning component 2 positions reinforcing plate 7, reinforcing plate 7 is fixed relative to base 1. Locking hook 8 is mounted in locking hook groove 71, and locking hook 8 is also fixed relative to base 1. Rotating arm 43 can rotate relative to base 1, and the shaped block 41 mounted on rotating arm 43 can move relative to the positioned locking hook 8, thereby setting locking hook 8 in locking hook groove 71 and then fixing locking hook 8, facilitating the use of fixture 100. Furthermore, rotating arm 43 can rotate relative to base 1, and the shaped block 41 mounted on rotating arm 43 can move relative to the welded locking hook reinforcing plate assembly 200, so as to release the limitation on locking hook reinforcing plate assembly 200 and facilitate the removal of locking hook reinforcing plate assembly 200 from fixture 100.

[0068] In some embodiments of the present invention, the hook positioning member 42 is connected to one of the rotating arms 43. Similarly, the hook positioning member 42 disposed on the rotating arm 43 can move relative to the positioned hook 8, thereby enabling the hook 8 to be placed in the hook groove 71 and then fixed, and facilitating the release of the limit on the hook reinforcing plate assembly 200, facilitating the use of the fixture 100, and making it easy to remove the hook reinforcing plate assembly 200 from the fixture 100. In addition, by disposing of the hook positioning member 42 on the rotating arm 43, by driving the rotating arm 43 to rotate relative to the base 1, the shape block 41 and the hook positioning member 42 can be moved simultaneously, which is convenient to use and eliminates the need for additional components to drive the hook positioning member 42 to move, thus reducing manufacturing costs.

[0069] In some specific embodiments of the present invention, such as Figure 3 and Figure 8 As shown, the locking hook positioning component 42 is connected to the rotating arm 43 where the second symbol block 41b is located, and the locking hook positioning component 42 is connected to the second symbol block 41b. The rotating arm 43 drives the second symbol block 41b to move while also driving the locking hook positioning component 42 to move.

[0070] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, each rotating arm 43 is equipped with a handrail 44, and the user can rotate the rotating arm 43 relative to the base 1 by manipulating the handrail 44.

[0071] In other embodiments of the invention, the fixture 100 includes a motor that drives the rotating arm 43 to rotate relative to the base 1.

[0072] In some embodiments of the present invention, such as Figure 5 As shown, the base 1 also has two stop arms 11 corresponding to each rotating arm 43. Each stop arm 11 has a stop groove. When the hook clamping assembly 4 clamps the hook 8, the rotating arm 43 is inserted into the stop groove. The rotating arm 43 can rotate relative to the base 1, and the shaped block 41 and the hook positioning member 42 can move relative to the positioned hook 8 for easy use. By setting the stop arm 11, the stop arm 11 can limit the rotation stroke of the rotating arm 43. When the hook clamping assembly 4 keeps the hook 8 fixed to the reinforcing plate 7, the stop arm 11 will position the rotating arm 43 so that the hook clamping assembly 4 is held in the position of clamping the hook 8.

[0073] When the hook clamping assembly 4 clamps the hook 8, the rotating arm 43 is inserted into the stop groove, and the rotating arm 43 cannot continue to rotate in the direction close to the base 1. After the locking block 41 and the hook positioning member 42 lock the ring segment 81 respectively, the rotating arm 43 is limited, and the hook clamping assembly 4 is held in the position of clamping the hook 8. The hook clamping assembly 4 keeps the hook 8 and the reinforcing plate 7 relatively fixed, improves the working stability of the welding process, and improves the product quality of the hook reinforcing plate assembly 200.

[0074] The following is for reference. Figures 1-4 The present invention describes the process of fixing the locking hook 8 and the reinforcing plate 7 relative to each other in a specific embodiment.

[0075] The reinforcing plate 7 is positioned by the positioning component 2, and is placed horizontally with its first surface at the bottom and its second surface at the top. The two rotating arms 43 are rotated away from the base 1 to open up the space above the reinforcing plate 7, so that the locking hook 8 can be placed in the locking hook groove 71.

[0076] After the locking hook 8 is placed in the locking hook groove 71, the two rotating arms 43 are driven by the handle 44 to rotate towards the base 1. When the rotating arm 43 is inserted into the stop groove, the first shaped block 41a on the rotating arm 43 cooperates with the first locking ring section 811, and the second shaped block 41b on the rotating arm 43 cooperates with the third locking ring section 813. The first shaped block 41a applies pressure to the first locking ring section 811 from left to right, and the second shaped block 41b applies pressure to the third locking ring section 813 from right to left. The locking hook positioning member 42 on the second shaped block 41b presses the second locking ring section 812 onto the reinforcing plate 7 from top to bottom. The locking hook clamping assembly 4 positions the locking hook 8 in the locking hook groove 71, keeping the locking hook 8 and the reinforcing plate 7 relatively fixed.

[0077] In some embodiments of the present invention, such as Figure 7 and Figure 8As shown, the positioning component 2 includes: a first column 21, the end face of the first column 21 is used to press against the first plate surface, a positioning groove 211 is provided on the end face of the first column 21, a part of the reinforcing plate 7 protrudes downward and is located in the positioning groove 211, and the lower end of the locking hook 8 is located at the position where the reinforcing plate 7 protrudes downward.

[0078] The first column 21 is used to position the reinforcing plate 7 for subsequent clamping and fixing. A portion of the reinforcing plate 7 protrudes downward to form a locking hook groove 71 on the second plate surface. A locking hook 8 is disposed in the locking hook groove 71 and welded to the reinforcing plate 7. By setting the locking hook groove 71, the locking hook 8 can be pre-positioned, ensuring accurate and uniform welding positions between the locking hook 8 and the reinforcing plate 7, thus improving the product quality of the locking hook reinforcing plate assembly 200. The first plate surface corresponding to the locking hook groove 71 is located within the positioning groove 211. The positioning groove 211 on the first column 21 and the locking hook groove 71 on the reinforcing plate 7 cooperate with each other to position the reinforcing plate 7.

[0079] In some specific embodiments of the present invention, there are two first columns 21, and the first column 21 is provided with two locking hook grooves 71 in a one-to-one correspondence. The first plate surface corresponding to the locking hook groove 71 is located in the positioning groove 211.

[0080] In some embodiments of the present invention, such as Figure 7 and Figure 8 As shown, the positioning component 2 includes at least one second post 22, each second post 22 having at least one positioning pin 221 for insertion into a positioning hole in the reinforcing plate 7. The positioning pin 221 on the second post 22 passes through the positioning hole in the reinforcing plate 7 to position the reinforcing plate 7.

[0081] In some specific embodiments of the present invention, two spaced-apart positioning holes are provided on the reinforcing plate 7. Correspondingly, the positioning component 2 includes two positioning pins 221, which correspond one-to-one with the positioning holes and pass through the positioning holes to further position the reinforcing plate 7. Compared with a design that only provides one positioning pin 221 to cooperate with the positioning hole, providing two positioning pins 221 to cooperate with the positioning hole can prevent the reinforcing plate 7 from rotating relative to the positioning pins 221, thus improving the stability of the reinforcing plate 7.

[0082] In some embodiments of the present invention, the fixture 100 further includes a lifting platform 5, which is mounted on the base 1 and is movable relative to the base 1. All support blocks 32 are mounted on the lifting platform 5, and the clamping block 31 is located above the support blocks 32. The lifting platform 5 can move all support blocks 32 closer to or away from the clamping block 31. When the lifting platform 5 moves all support blocks 32 upward, it can drive all plate clamping pairs 3 and reinforcing plates 7 to clamp and fix them.

[0083] In some embodiments of the present invention, the reinforcing plate 7 is positioned on the lifting platform 5, and the support block 32 is adapted to support the reinforcing plate 7 after positioning. After the positioning assembly 2 positions the reinforcing plate 7, the lifting platform 5 drives all the support blocks 32 to rise, the support blocks 32 press against the first plate surface, and the clamping block 31 presses against the second plate surface. The clamping block 31 and the support block 32 together apply pressure to the reinforcing plate 7 to clamp and fix the reinforcing plate 7. After the locking hook 8 and the reinforcing plate 7 are welded into the locking hook reinforcing plate assembly 200, the lifting platform 5 drives all the support blocks 32 to fall, thereby removing the fixation of the reinforcing plate 7 and facilitating the removal of the locking hook reinforcing plate assembly 200 from the fixture 100.

[0084] In some embodiments of the present invention, the positioning component 2 is disposed on the lifting platform 5, thereby positioning the reinforcing plate 7 on the lifting platform 5. For example... Figure 7 and Figure 8 As shown, two first columns 21 extending in the vertical direction are provided on the lifting platform 5, and positioning grooves 211 are provided on the end faces of the first columns 21. Two second columns 22 extending in the vertical direction are also provided on the lifting platform 5, and each second column 22 is provided with a positioning pin 221. The first columns 21 and the second columns 22 together position the reinforcing plate 7 on the lifting platform 5.

[0085] In some embodiments of the present invention, the lifting platform 5 is further provided with a plurality of support columns 51, and each support column 51 is provided with a support block 32 at its top. For example... Figure 7 and Figure 8 As shown, when the first column 21 and the second column 22 position the reinforcing plate 7 on the lifting platform 5, the reinforcing plate 7 is placed on the support column 51, and the support block 32 at the top of the support column 51 jointly supports the reinforcing plate 7 after it is positioned.

[0086] In some embodiments of the present invention, such as Figure 3 , Figure 8 and Figure 9 As shown, the base 1 is provided with two parallel connecting rods 12, which are located above the support block 32. Each connecting rod 12 is connected to two clamping blocks 31 at both ends. Therefore, the fixture 100 of this embodiment includes eight clamping blocks 31, and the clamping blocks 31 and the support blocks 32 are arranged in a one-to-one correspondence. Correspondingly, the lifting platform 5 is provided with eight support columns 51, and the top of each support column 51 is provided with a support block 32. The eight clamping blocks 31 and the eight support blocks 32 are arranged facing each other in the vertical direction.

[0087] like Figure 1 and Figure 4As shown, the reinforcing plate 7 is a quadrilateral plate. The fixture 100 of this embodiment includes eight plate clamping pairs 3. The eight plate clamping pairs 3 are respectively arranged at the four corners of the reinforcing plate 7, and two plate clamping pairs 3 are arranged at each corner to form over-constraint on the corners of the reinforcing plate 7. The reinforcing plate 7 is subjected to uniform force, reducing the deformation of the reinforcing plate 7 during the welding process.

[0088] In some embodiments of the present invention, the reinforcing plate 7 is adapted to be placed laterally on the fixture 100, such as... Figure 4 As shown, the reinforcing plate 7 includes flange areas 72 located at the four corners and raised areas 73 that protrude upwards relative to the flange areas 72. Figure 9 As shown, after the reinforcing plate 7 is positioned horizontally, the portion between the corners of the reinforcing plate 7 protrudes upward in the left-right direction to form a raised area 73. The height of the plate surface of the raised area 73 is higher than the height of the plate surface of the flange area 72.

[0089] Each corner of the reinforcing plate 7 is suitable for clamping two plate clamping pairs 3, one of which is clamped in the flange area 72 and the other in the raised area 73. The clamping block 31 in the raised area 73 is higher than the clamping block 31 in the flange area 72. The plate clamping pairs 3 clamped in the flange area 72 clamp and fix the reinforcing plate 7 at the four corners, and the four plate clamping pairs 3 clamped in the raised area 73 clamp and fix the edges extending in the left and right directions. The multiple plate clamping pairs 3 not only clamp and fix the reinforcing plate 7 at multiple locations, but also clamp and fix the plate surfaces of the reinforcing plate 7 at different heights, further fixing the reinforcing plate 7, reducing the deformation of the reinforcing plate 7 during welding, and improving the product quality of the locking hook reinforcing plate assembly 200.

[0090] The eight plate clamping pairs 3 are divided into two groups. The first group of plate clamping pairs 3 is clamped in the flange area 72 to clamp and fix the four corners of the reinforcing plate 7. The second group of plate clamping pairs 3 is added to the raised area 73 to clamp and fix the edge extending in the left and right direction. Each corner of the reinforcing plate 7 is suitable to be provided with one plate clamping pair 3 from the first group of plate clamping pairs 3 and one plate clamping pair 3 from the second group of plate clamping pairs 3.

[0091] In some specific embodiments of the present invention, such as Figure 2 , Figure 3 and Figure 9As shown, the connecting rod 12 extends in the front-to-back direction, and two clamping blocks 31 are connected to each end of the connecting rod 12. Taking the two clamping blocks 31 at one end of the connecting rod 12 as an example, the clamping block 31 of the first set of plate clamping pairs 3 is connected to the lower end of the connecting rod 12, and the clamping block 31 of the second set of plate clamping pairs 3 is connected to the upper end of the connecting rod 12. The clamping block 31 of the second set of plate clamping pairs 3 is higher than the clamping block 31 of the first set of plate clamping pairs 3. Correspondingly, eight support columns 51 are provided on the lifting platform 5. The support blocks 32 at the top of four support columns 51 are constructed as support blocks 32 of the first set of plate clamping pairs 3, and the support blocks 32 at the top of the other four support columns 51 are constructed as support blocks 32 of the second set of plate clamping pairs 3. The support blocks 32 of the second set of plate clamping pairs 3 are higher than the support blocks 32 of the first set of plate clamping pairs 3. The eight plate clamping pairs 3 not only clamp and fix the reinforcing plate 7 at multiple points, but also clamp and fix the reinforcing plate 7 at different heights, further fixing the reinforcing plate 7, reducing the amount of deformation of the reinforcing plate 7 during welding, and improving the product quality of the locking hook reinforcing plate assembly 200.

[0092] like Figure 3 As shown, in the left-right direction, the four plate clamping pairs 3 are arranged at intervals along the same straight line, the reinforcing plate 7 is subjected to uniform force, which can firmly fix the reinforcing plate 7 and reduce the amount of deformation generated by the reinforcing plate 7 during the welding process.

[0093] In some embodiments of the present invention, the connecting rod 12 is fixedly connected to the base 1, the position of the clamping block 31 on the connecting rod 12 and the base 1 is fixed, the lifting platform 5 can be raised and lowered relative to the base 1, and the lifting platform 5 can drive all the support blocks 32 to move closer to or away from the clamping block 31.

[0094] In other embodiments of the present invention, two connecting rods 12 are respectively connected to corresponding rotating arms 43. When the rotating arm 43 is inserted into the stop groove, the connecting rod on the rotating arm 43 is also limited, and the position between the clamping block 31 on the connecting rod 12 and the base 1 is fixed. At this time, the lifting platform 5 can be raised and lowered relative to the base 1, and the lifting platform 5 can drive all the support blocks 32 to move closer to or away from the clamping block 31. It is worth noting that when the rotating arm 43 is inserted into the stop groove, the clamping block 31 on the connecting rod 12 and the support block 32 are directly opposite each other in the vertical direction, and the lifting platform 5 can drive all the support blocks 32 to move closer to the clamping block 31 to stably clamp the reinforcing plate 7.

[0095] When the rotating arm 43 rotates in a direction away from the base 1, the rotating arm 43 can drive the connecting rod to open the upper space of the lifting platform 5, which makes it convenient to place the reinforcing plate 7 on the lifting platform 5 for positioning, avoids interference with the reinforcing plate 7, and facilitates the use of the fixture 100.

[0096] In some embodiments of the present invention, the fixture 100 further includes a cylinder connected to the lifting platform 5. The cylinder is used to drive the lifting platform 5 to move up and down, facilitating the use of the fixture 100.

[0097] In some embodiments of the present invention, such as Figure 1 As shown, the fixture 100 also includes a fixture push-button switch 6, which is electrically connected to the cylinder. The cylinder can be controlled by operating the fixture push-button switch 6.

[0098] In some specific embodiments of the present invention, the base 1 is disposed on a base plate, and the base plate is provided with a plurality of holes to facilitate the installation of the base 1.

[0099] The following is for reference. Figures 1-9 The working process of the fixture 100 in a specific embodiment of the present invention is described.

[0100] First, hold the two handrails 44 and rotate the two rotating arms 43 in a direction away from the base 1 to open up the space above the lifting platform 5.

[0101] Next, the reinforcing plate 7 is placed horizontally on the lifting platform 5 with the first plate surface facing down and the second plate surface facing up. The two positioning holes on the reinforcing plate 7 are inserted into the positioning pins 221 on the second column 22, and the first plate surface corresponding to the welding groove is placed in the positioning groove 211 on the first column 21 to complete the positioning of the reinforcing plate 7.

[0102] Subsequently, the locking hook 8 is placed in the locking hook groove 71, and the two rotating arms 43 are driven by the handle 44 to rotate towards the base 1. When the rotating arms 43 are inserted into the stop groove, the first shaped block 41a on the rotating arm 43 cooperates with the first locking ring segment 811, and the second shaped block 41b on the rotating arm 43 cooperates with the third locking ring segment 813. The first shaped block 41a applies pressure to the first locking ring segment 811 from left to right, and the second shaped block 41b applies pressure to the third locking ring segment 813 from right to left. The locking hook positioning member 42 on the second shaped block 41b presses the second locking ring segment 812 tightly from top to bottom. The locking hook clamping assembly 4 positions the locking hook 8 in the locking hook groove 71, keeping the locking hook 8 relatively fixed to the reinforcing plate 7, thus completing the positioning of the locking hook 8.

[0103] Then, the lifting platform 5 is driven upward by the cylinder. The lifting platform 5 drives all the support blocks 32 to rise. The support blocks 32 press against the first plate surface, and the clamping block 31 presses against the second plate surface. The clamping block 31 and the support block 32 together apply pressure to the reinforcing plate 7 to clamp and fix the reinforcing plate 7. At the same time, the support block 32 and the locking hook positioning member 42 together apply pressure to the locking hook 8 to clamp and fix the locking hook 8, thus completing the fixation of the reinforcing plate 7 and the locking hook 8.

[0104] Finally, the locking hook 8 is welded to the reinforcing plate 7 to form the locking hook reinforcing plate assembly 200, thus completing the manufacturing of the locking hook reinforcing plate assembly 200. By applying the fixture 100 of this invention, the deformation of the reinforcing plate 7 during welding can be reduced, improving the product quality of the locking hook reinforcing plate assembly 200.

[0105] The process of removing the hook reinforcement plate assembly 200 from the fixture 100 is simpler and the reverse of the above process. First, the lifting platform 5 is moved downward using a cylinder. Then, the two handrails 44 are held, and the two rotating arms 43 are rotated away from the base 1, thereby releasing the restriction on the hook reinforcement plate assembly 200. The hook 8 assembly and the reinforcement plate 7 assembly can then be removed from the lifting platform.
