Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] Figure 1 This is a schematic diagram of the clamp positioning structure used in a specific embodiment of this application. Figure 2 for Figure 1 The exploded view of the clamp positioning structure shown. Figure 3 for Figure 1 A partial schematic diagram of the clamp positioning structure is shown. Figures 1 to 3 As shown, the fixture positioning structure includes a base 1, two clamping mechanisms and a drive mechanism.

[0025] The base 1 has two opposing and spaced-apart slide rails 10, and each slide rail 10 has two opposing and spaced-apart slide rail seats 16. The base 1 is usually fixed in a designated position, for example, the bottom of the base 1 is connected to the clamp base by a fixing pin. After positioning, the base 1 and the clamp base are connected by bolts. The slide rails 10 are located on the top of the base 1, extending along the length of the base 1, and the two slide rails 10 are parallel to each other along the width of the base 1. The slide rails 10 are connected to the base 1 by fixing pins and bolts. After initial positioning, the position of the slide rails 10 is positioned using fixing pins and then connected to the base 1 by bolts. Each slide rail 10 has two slide rail seats 16, and the positions of the slide rail seats 16 on the two slide rails 10 are one-to-one. The slide rail seats 16 can reciprocate along the slide rail 10.

[0026] Each clamping mechanism connects to the slide rail seat 16 on the same side of two slide rails 10. The clamping mechanism is equipped with an angle seat 9, allowing the two clamping mechanisms to move closer or further apart via the angle seats 9 to extract or release the mating component. The clamping mechanism is connected to the slide rail seat 16 on the same side of the two slide rails 10. When the two slide rail seats 16 below the clamping mechanism reciprocate along the two slide rails 10, the clamping mechanism achieves reciprocating movement relative to the slide rails 10. The two clamping mechanisms can move closer together to extract or clamp the mating component; the two clamping mechanisms can also move further apart to release the mating component. The mating component includes, but is not limited to, the second crossbeam of the frame assembly.

[0027] In one embodiment of this application, the corner bracket 9 is structurally matched with the second crossbeam of the frame assembly. The corner bracket 9 includes a horizontal corner bracket 9 plate and a vertical corner bracket 9 plate. The horizontal corner bracket 9 plate is disposed on top of the clamping mechanism. A groove is provided on the outer side of the connection between the horizontal and vertical corner bracket 9 plates, and reinforcing ribs are provided on the inner side of the connection between the two connection points. The horizontal and vertical corner bracket 9 plates contact the second crossbeam of the frame assembly through their outer sides. The vertical corner bracket 9 plate of the corner bracket 9 is provided with multiple positioning mechanisms, such as a clearance groove at the top of the vertical corner bracket 9 plate, multiple rows of horizontal and / or vertical positioning holes, mounting holes, and support arms. The two corner brackets 9 can stably clamp the second crossbeam of the frame assembly.

[0028] In one embodiment of this application, the two corner brackets 9 have similar structures, that is, the horizontal corner bracket 9 plates have the same structure, but the vertical corner bracket 9 plates have different structures. One of the vertical corner bracket 9 plates has a mounting hole and a longer support arm. The top of this vertical corner bracket 9 plate has a centrally located extension plate, and the two sides of the extension plate form clearance grooves with the vertical corner bracket 9 plate respectively. The other vertical corner bracket 9 plate does not have a mounting hole and the support arm has a relatively shorter length. The top of this vertical corner bracket 9 plate has an extension plate, and the vertical corner bracket 9 plate forms a clearance groove on one side of the extension plate.

[0029] The drive mechanism is used to drive two clamping mechanisms to reciprocate along the slide rail 10, and can lock or unlock the relative position of the two clamping mechanisms. The drive mechanism can drive the clamping mechanisms to reciprocate, adjusting their relative position and the distance between them. When the clamping mechanism achieves positioning and picks up the mating part, the drive mechanism drives the two clamping mechanisms closer together to lock the position of the mating part. When the mating part is assembled or the operation is completed, the drive mechanism drives the two clamping mechanisms away from each other to release the mating part.

[0030] Each clamping mechanism is connected to a slide rail seat 16 on the same side of two slide rails 10. The four slide rail seats 16 are divided into two groups of traveling units by the two clamping mechanisms. When the two slide rail seats 16 below the clamping mechanism reciprocate along the two slide rails 10, the clamping mechanism achieves reciprocating movement relative to the slide rails 10. The drive mechanism can drive the clamping mechanisms to reciprocate, and to move closer or further apart, to adjust the relative position of the clamping mechanisms and the distance between the two clamping mechanisms. When the clamping mechanism achieves positioning and picks up the mating part, the drive mechanism drives the two clamping mechanisms to move closer together to lock the position of the mating part. When the mating part is assembled or the operation is completed, the drive mechanism drives the two clamping mechanisms to move away from each other to release the mating part.

[0031] Using the aforementioned clamping positioning structure, the slide rail seat 16 on the slide rail 10 can slide synchronously under the action of the drive mechanism, enabling the clamping mechanism to quickly and accurately position and extract or release the mating parts at the designated location. In particular, the use of the angle seat 9 can solve the inconvenience caused by the spatial and posture defects of the components of the second crossbeam of the frame assembly on the clamp, avoid the problems of long assembly time and difficulty in assembly caused by the use of traditional positioning mechanisms, improve the convenience of operation, quickly complete synchronous positioning, and improve the efficiency of disassembly and assembly.

[0032] To improve operational accuracy, the drive mechanism optionally includes a first drive mechanism 7 and a second drive mechanism. The first drive mechanism 7 drives the two clamping mechanisms to move synchronously; the second drive mechanism locks or unlocks the relative positions of the two clamping mechanisms to release or extract the mating parts. The first drive mechanism 7 is located on the same side of the two slide rails 10, and by driving the two clamping mechanisms or the two clamping mechanisms to move relative to the slide rail seats 16 below, it achieves synchronous movement of the four slide rail seats 16. The second drive mechanism is located between the two slide rails 10, and by driving the two clamping mechanisms to move towards or away from each other, it achieves clamping or releasing actions on the mating parts. The first drive mechanism 7 and the second drive mechanism cooperate to realize the movement and locking steps of the clamping mechanisms, thereby achieving precise control of the clamping mechanisms.

[0033] Optionally, the first drive mechanism 7 includes a handle 71, a first connecting rod 72, a second connecting rod 73, a first connecting seat 74, and a second connecting seat 75. The handle 71 and the first connecting seat 74 are respectively connected to opposite ends of the first connecting rod 72. The first connecting seat 74 is fixed to the slide rail seat 16 or the clamping mechanism. The second connecting rod 73 is rotatably connected to the first connecting rod 72 and is connected to the slide rail seat 16 or the clamping mechanism through the second connecting seat 75. When force is applied to the handle 71, the handle 71 drives the first connecting rod 72, and the first connecting rod 72 drives the second connecting rod 73 to move synchronously. The first connecting rod 72 and the second connecting rod 73 respectively drive the two clamping mechanisms or the four slide rail seats 16 to move synchronously through the first connecting seat 74 and the second connecting seat 75, so as to achieve the purpose of synchronous movement of the slide rail seats 16. At the same time, the second connecting rod 73 and the first connecting rod 72 are rotatably connected, and the distance between the two clamping mechanisms is relatively increased, which facilitates the release or loading of mating parts.

[0034] In one embodiment of this application, the first connecting rod 72 is a broken line segment, and the second connecting rod 73 is a straight line segment. The upper end of the first connecting rod 72 is threadedly connected to the handle 71, and the lower end of the first connecting rod 72 is bolted to the first connecting seat 74, and is connected to the slide rail seat 16 or the clamping mechanism through the first connecting seat 74. The upper end of the second connecting rod 73 is rotatably connected to the first connecting rod 72, and the lower end of the second connecting rod 73 is connected to the second connecting seat 75, and is connected to the slide rail seat 16 or the clamping mechanism through the second connecting seat 75.

[0035] To prevent the slide rail seat 16 from detaching from the slide rail 10, optionally, the base 1 is provided with a first limiting block 2 and a second limiting block 12 that are opposite to each other and spaced apart. The first limiting block 2 and the second limiting block 12 are used to limit the maximum driving displacement of the first driving mechanism 7. The first driving mechanism 7 can drive the four slide rail seats 16 to move synchronously. The first limiting block 2 and the second limiting block 12 are respectively located at both ends or at preset positions in the length direction of the top of the base 1. By limiting the driving position of the first driving mechanism 7, the displacement of the slide rail seat 16 is limited.

[0036] In one embodiment of this application, the first limiting block 2 and the second limiting block 12 adopt the same or similar structures. The first limiting block 2 and the second limiting block 12 are symmetrically arranged along the length centerline of the base 1.

[0037] In one embodiment of this application, the first limiting block 2 and the second limiting block 12 have the same structure. Taking the first limiting block 2 as an example, the first limiting block 2 includes a horizontal block and a vertical block extending from one end of the horizontal block. The horizontal block is connected to the base 1 by bolts; the vertical block is used to prevent the first driving mechanism 7 from moving further.

[0038] To achieve precise control over extraction and release, the second drive mechanism optionally includes a cylinder, a fixed seat 15, and a movable seat 13. The fixed seat 15 and the movable seat 13 are respectively connected to two clamping mechanisms. The opposite ends of the cylinder are connected to the fixed seat 15 and the movable seat 13, respectively. The cylinder can drive the movable seat 13 to move the clamping mechanism above it closer to or away from the clamping mechanism above the fixed seat 15. The fixed end of the cylinder body is connected to the fixed seat 15, which is connected to one clamping mechanism. The movable end of the cylinder body is connected to the movable seat 13, which is connected to the other clamping mechanism. When the movable end of the cylinder body extends or retracts, it drives the movable seat 13 to reciprocate, allowing the clamping mechanism connected to the movable seat 13 to move closer to or away from the clamping mechanism connected to the fixed seat 15, thereby achieving the locking or unlocking action of the two clamping mechanisms.

[0039] In one embodiment of this application, the fixed seat 15 and the movable seat 13 adopt the same or similar structure. The fixed seat 15 includes a horizontal fixed plate and a vertical fixed plate. The horizontal fixed plate is connected to the clamping mechanism, and the vertical fixed plate is connected to the fixed end of the cylinder. The main difference between the movable seat 13 and the fixed seat 15 is that the vertical fixed plate of the movable seat 13 is provided with a clearance opening, which facilitates the enhancement of the connection strength between the cylinder and the movable seat 13.

[0040] In one embodiment of this application, the cylinder includes a cylinder body 14 and a cylinder connecting rod 17. The cylinder body 14 is connected to the cylinder connecting rod 17, and the cylinder connecting rod 17 is capable of reciprocating along the cylinder body 14. The free end of the cylinder body 14 is a fixed end, and the free end of the cylinder connecting rod 17 is a movable end.

[0041] To facilitate assembly and achieve good synchronization, the clamping mechanism optionally includes a mounting plate 8 and corner brackets 9 mounted on the mounting plate 8. The mounting plate 8 connects the slide rail seats 16 on the same side of the two slide rails 10. The mounting plate 8 is connected to the two slide rail seats 16 on the same side of the two slide rails 10. The mounting plate 8 and the slide rail seats 16 can be fixed together, such as by welding, or they can be detachably connected, such as by snap-fit ​​connection or bolt connection. The mounting plate 8 is T-shaped. The opposite ends of the horizontal plate of the T-shaped plate are connected to the slide rail seats 16 respectively. The vertical plate and the horizontal plate of the T-shaped plate together support the corner brackets 9 and the mounting fixed seat 15 or movable seat 13. The horizontal corner bracket 9 is bolted to the top surface of the mounting plate 8, and the fixed seat 15 or movable seat 13 is bolted to the bottom surface of the mounting plate 8.

[0042] In one embodiment of this application, the bottom surfaces of the mounting plate 8 are connected to the slide rail seat 16 at opposite ends by fixing pins. After initial positioning, they are fixed by bolts. The top surface of the mounting plate 8 is connected to the horizontal corner seat 9 plate of the corner seat 9 by fixing pins. After initial positioning, it is fixed by bolts.

[0043] Optionally, the base 1 includes a bottom plate, a top plate, and a side wall disposed between the bottom plate and the top plate. The bottom plate is used to fix the base 1 in a designated position, and two slide rails 10 are distributed parallel to each other at opposite ends of the top plate. The top plate and the bottom plate are disposed opposite to each other, and the bottom plate is connected to the clamp base by a fixing pin. After positioning, the base 1 and the clamp base are connected by bolts. The top plate provides support for the slide rails 10 and the clamping mechanism above the slide rails 10.

[0044] In one embodiment of this application, the sidewall includes two first sidewalls extending along the length direction of the top plate and the bottom plate, and a second sidewall extending along the width direction of the top plate and the bottom plate. The opposite ends of the first sidewalls are connected to the top plate and the bottom plate, respectively, and clearance holes are provided on the first sidewalls. The second sidewall is only connected to the bottom plate, and a clearance space is provided between the top end of the second sidewall and the top plate. The cylinder is disposed within the space enclosed by the sidewalls, which facilitates the installation of the fixed seat 15 and the movable seat 13, and at the same time provides working space for the cylinder.

[0045] To further optimize the structure, optionally, a first groove and a second groove are provided on opposite sides of the top plate, respectively. Both the first and second grooves are positioned between the two slide rails 10, centrally located, and extend from the side edges towards the center. A fixed seat 15 is disposed within the first groove, and a second drive mechanism can drive the movable seat 13 to reciprocate within the second groove.

[0046] In one embodiment of this application, the top plate is H-shaped, two slide rails 10 are respectively installed on the two vertical plates of the H-shaped plate, and the fixing limit block 5 is set on the horizontal plate of the H-shaped plate.

[0047] To improve dustproof performance, the clamp positioning structure may optionally include: a fixed limiting block 5, a first slide rail 10 dustproof seat 3, and a second slide rail 10 dustproof seat 6. The fixed limiting block 5 is disposed on the base 1 and located between the first groove and the second groove. The first slide rail 10 dustproof seat 3 and the second slide rail 10 dustproof seat 6 are respectively disposed at opposite ends of the fixed limiting block 5 and are used to partially cover the two slide rails 10. The first slide rail 10 dustproof seat 3 and the second slide rail 10 dustproof seat 6 provide partial shielding between the two slide rail seats 16 on each side of the slide rail 10, preventing dust from entering the slide rail 10 and affecting the smooth movement of the slide rail seats 16.

[0048] In one embodiment of this application, the fixed limiting block 5 is fixed to the base 1 by bolts and is located between the first groove and the second groove.

[0049] In one embodiment of this application, the dustproof seat 3 of the first slide rail 10 and the dustproof seat 6 of the second slide rail 10 adopt the same or similar structure. The first limiting block 2 and the second limiting block 12 are symmetrically arranged along the width centerline of the base 1.

[0050] In one embodiment of this application, the first slide rail 10 dustproof seat 3 and the second slide rail 10 dustproof seat 6 adopt the same structure. Taking the first slide rail 10 dustproof seat 3 as an example, the first slide rail 10 dustproof seat 3 includes a horizontal plate and a vertical plate extending from one end of the horizontal plate. The vertical plate is connected to the side of the fixed limiting block 5 by bolts; the horizontal plate is used to provide a shielding function for the slide rail 10.

[0051] To improve positioning accuracy, the fixture positioning structure may optionally include a first sliding limit block 4 and a second sliding limit block 11. The first sliding limit block 4 and the second sliding limit block 11 are symmetrically connected to opposite sides of the fixed limit block 5 and are used to limit the movement positions of the two clamping mechanisms, respectively. When the first groove moves relative to the mounting plate 8 above it and contacts its adjacent fixed limit block 5, it will be unable to move further. Similarly, when the second groove moves relative to the mounting plate 8 above it and contacts its adjacent fixed limit block 5, it will be unable to move further.

[0052] In one embodiment of this application, grooves are provided on opposite sides of the top of the fixed limiting block 5, and the first sliding limiting block 4 and the second sliding limiting block 11 are respectively disposed in the two grooves.

[0053] In one embodiment of this application, the first sliding limiting block 4 and the second sliding limiting block 11 adopt the same or similar structure. Taking the first limiting block 2 as an example, the first limiting block 2 is disposed in the groove and is connected to the fixed limiting block 5 by a fixing pin.

[0054] The following section further describes the usage process of the clamp positioning structure.

[0055] First, the drive handle 71 moves, driving the first connecting seat 74 and the second connecting seat 75 via the first link 72 and the second link 73 respectively. The first connecting seat 74 and the second connecting seat 75 drive the two clamping mechanisms to move synchronously along the slide rail 10. That is, the two mounting plates 8 simultaneously drive the four slide rail seats 16 to move along the slide rail 10. After moving to the designated position, the drive handle 71 stops. The cylinder is then activated, extending and retracting to drive the movable seat 13 closer to or away from the fixed seat 15, so as to drive the two clamping mechanisms closer to or further away from each other. For example, the cylinder drives the movable seat 13 away from the fixed seat 15, increasing the distance between the two clamping mechanisms and providing sufficient working space for the mating parts. After the mating parts are installed between the two corner seats 9, the cylinder drives the movable seat 13 closer to the fixed seat 15, decreasing the distance between the two clamping mechanisms to clamp and limit the mating parts. The drive handle 71 moves in the opposite direction, moving the whole assembly to the designated position or after assembly is completed. Then, the cylinder drives the movable seat 13 away from the fixed seat 15, increasing the distance between the two clamping mechanisms and releasing the mating parts.

[0056] Taking the second crossbeam component as an example, the second crossbeam component is placed in the tooling positioning position, and the drive handle 71 is moved. The handle 71 drives the first connecting seat 74 and the second connecting seat 75 respectively through the first connecting rod 72 and the second connecting rod 73. The first connecting seat 74 and the second connecting seat 75 drive the two clamping mechanisms to move synchronously along the slide rail 10. That is, the two mounting plates 8 simultaneously drive the four slide rail seats 16 to move along the slide rail 10. After moving to the designated position, the second crossbeam component is positioned between the two corner seats 9, and the drive handle 71 is stopped. The cylinder is started, and the cylinder drives the moving seat 13 to move closer to the fixed seat 15, that is, the distance between the two clamping mechanisms is reduced, so as to clamp and fix the second crossbeam component, so that the second crossbeam component is in place according to the theoretical reference of the fixture. Welding is performed by CO2 welding. After completion, the cylinder drives the moving seat 13 away from the fixed seat 15, that is, the distance between the two clamping mechanisms is increased, and the second crossbeam component is released.

[0057] This application also provides a clamp, which includes at least one clamp positioning structure as described above. The clamp can employ any of the clamp positioning structures described above, and will not be elaborated further here.

[0058] As can be seen from the above description and practice, the clamp positioning structure and clamp provided in this application have the following advantages compared with the prior art: Using the above-mentioned clamp positioning structure, under the action of the drive mechanism, the slide rail seat 16 on the slide rail 10 can slide synchronously, enabling the clamping mechanism to quickly and accurately position and extract or release the mating parts at the designated position. In particular, the use of the angle seat 9 can solve the inconvenience caused by the spatial and posture defects of the components of the second crossbeam of the frame assembly on the clamp, avoiding the problems of long assembly time and difficulty caused by the use of traditional positioning mechanisms, improving operational convenience, quickly completing synchronous positioning, and improving disassembly and assembly efficiency.

[0059] Those skilled in the art should understand that the above description is merely a specific embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the scope of this application should be included within the protection scope of this application.
