Description

Technical Field

[0001] This invention relates to the field of automotive parts processing equipment, and in particular to a flipping fixture mechanism driven by linear gears. Background Technology

[0002] In the process of processing the automotive floor crossbeam assembly (also known as the automotive floor 6# crossbeam assembly), our company needs to flip the entire part according to the different welding positions to meet the welding requirements of the welding gun. However, traditional welding fixtures require manual methods to complete the flipping action, which not only fails to improve work efficiency but also increases the risk to operators.

[0003] The welding fixtures for automotive floor crossbeam assemblies are usually quite heavy. In this case, traditional tilting mechanisms are prone to structural instability and instability, which can lead to serious safety accidents and even personal injury or death.

[0004] The relatively complex flipping structure can also have an adverse impact on the cost control of parts. At this time, the inventor needs to conduct relevant research on how to balance cost and good flipping performance. Summary of the Invention

[0104] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific embodiments.

[0105] Example 1: An embodiment of the present invention provides a flipping clamp mechanism driven by linear gears, see [link to example]. Figure 1-32 As shown, it includes: a frame 1, a tooling tilting cavity 2, a tooling plate frame structure 3, a suspension ear assembly 4, a reinforcing component assembly clamping unit 5, a floor beam assembly clamping unit 6, a disc assembly 7, a left bearing seat 8, a right bearing seat 9, a left bearing seat adjusting device 10, a right bearing seat adjusting device 11, a drive gear 12, a horizontal support plate 13, a motion track 14, a slider 15, a horizontal T-block 16, a rack 29, a drive device 30, a stop buffer assembly, and a control module, which is connected to the drive device and drive cylinder, etc.

[0106] See also Figure 1 The frame 1 can be assembled from metal tubes, including but not limited to welding assembly and assembly with bolts and studs. In this embodiment, the frame, as the load-bearing body of the entire equipment, mainly includes a left frame 1-1, a right frame 1-2, and a bottom frame 1-3 set on the left and right frames. This frame structure can achieve lightweighting while ensuring the strength of the overall structure. The left frame, right frame, and bottom frame enclose and form the tooling tilting cavity 2, which provides a guarantee for welding operations at different angles of the parts. The tooling unit is one of the core structures of this equipment. Different accessories are arranged on it to meet the fixing needs of the parts to be processed. The tooling unit includes a U-shaped tooling plate frame structure 3. The use of a plate frame structure can avoid the problem of difficult tilting operation due to excessive weight, and the large weight also increases the difficulty of transportation of the equipment to varying degrees. Suspension ear assemblies 4 are distributed on the left and right sides of the tooling frame structure, allowing the main body of the frame structure to be suspended in the tooling flipping cavity 2. A reinforcing component assembly-clamping unit 5 is provided on the right side of the tooling frame structure, and floor beam assembly clamping units 6 distributed on the left side of the reinforcing component assembly-clamping unit are provided on the left side of the tooling frame structure. Figure 1 The document specifies reinforcement component P1 and floor beam assembly P2. (Reinforcement component P1 needs to be welded to floor beam assembly P2 in subsequent processes. The reason for welding them to other fixtures later is that welding on this fixture would cause interference issues; therefore, reinforcement component P1 needs to be pulled out and welded separately.) See also... Figure 11The tooling frame structure 3 of the linear gear-driven flipping fixture mechanism provided by this invention is a rectangular frame 3-1. This rectangular frame has a left longitudinal beam, a right longitudinal beam, and a front and rear crossbeam positioned between the longitudinal beams. The rectangular frame is welded from rectangular metal tubing. A horizontal U-shaped plate 3-2 is provided on the right side of the rectangular frame. The notch in the horizontal U-shaped plate 3-2 allows the corresponding cylinder assembly to be located there, improving space utilization while reducing the weight of the tooling fixture. The horizontal U-shaped plate 3-2 fixes the L-shaped suspension portion 4-6 of the suspension ear assembly 4. The L-shaped suspension portion 4-6 is welded from metal plates or assembled with bolts. Triangular reinforcing ribs are added to the mutually perpendicular transition surfaces to improve structural strength. The rectangular frame has a right longitudinal beam 3-3 made of metal square tubes and a left longitudinal beam 3-4 made of metal square tubes. The presence of the two longitudinal beams increases the installation stability of the middle strip plate and the left working plate. The right longitudinal beam is equipped with a middle strip plate 3-5. The large gap between the middle strip plate 3-5 and the horizontal U-shaped plate 3-2 can reduce the self-weight of the tooling fixture, and the corresponding cylinder assembly can be arranged in this large gap. On the left side of the rectangular frame, there is a left working plate 3-6 with a hollow structure. This left working plate is the plate structure with the largest area on the tooling fixture. The self-weight is reduced by the hollow structure. The horizontal U-shaped plate is used to arrange the reinforcing component assembly - clamping unit 5. The floor beam assembly clamping unit 6 is arranged at the left working plate and the middle strip plate.

[0107] See Figure 1 The suspension ear assembly of the tooling plate frame structure is provided with a coaxially distributed disc assembly 7. The disc in this disc assembly is integrally formed from metal, and the disc has 12 groups of stop block fixing holes arranged in a circular array. Each group of stop block fixing holes consists of two rows and three columns of circular holes. Since the entire disc has 12 groups of stop block fixing holes, the included angle between adjacent groups of stop block fixing holes is 30°. This distribution is beneficial for installing stop blocks at different positions according to the needs of the part to be processed. In this embodiment, Figure 2 The group of fixing holes for the first fixing block 17 is defined as the No. 1 fixing hole group, along the counterclockwise direction of the disk ( Figure 2 (The direction indicated by the middle arrow W is counterclockwise) are, in sequence, the fixing hole groups of stop blocks No. 2, No. 3, ... No. 12. In this embodiment, a second stop block 18 is installed in the fixing hole group of stop blocks No. 3. Figure 1-2 The state shown is the first working state of the part to be processed. At this time, the tooling plate is in a horizontal state, and the second stop block 18 is in the stop position (cooperating with the first stop buffer assembly R1, detailed description below). When the first stop block is raised and the disc rotates 90 degrees clockwise, the first stop block 17 can be used in conjunction with the second stop buffer assembly R2. This fixture has only two working positions, namely... Figure 1 The tooling plate shown is in a horizontal position, and another workstation is along... Figure 2 Rotate 90 degrees clockwise. At this point, the first stop block engages, and the tooling plate is positioned in the vertical device (i.e., perpendicular to the workpiece). Figure 1 (The states shown are perpendicular to each other). The left frame is equipped with a left bearing housing 8, and the left bearing housing is fitted with one of the disc assemblies connected to the tooling frame structure (i.e., Figure 1 (In the state of the left-side disk assembly), the left bearing housing is equipped with a left bearing housing adjustment device 10, which can adjust the position of the left bearing housing in the X and Y directions. Figure 1 (The left-right direction is defined as the X direction, and the front-back direction as the Y direction). By fine-tuning the position of the bearing housing, the coaxiality of the shaft installation can be improved, and the displacement of the bearing housing caused by vibration can be reduced. See also Figure 2 A drive gear 12 is mounted on the left bearing housing 8 at the end furthest from the disc assembly. This drive gear is suspended to facilitate engagement with the rack below. A horizontal support plate 13 with supporting ribs is provided on the side of the left frame. The support ribs ensure the installation strength of the horizontal support plate and improve the overall shape of the equipment. A motion track 14 is provided on the horizontal support plate, which is distributed along the length of the horizontal support plate. The motion track is rectangular and fixed to the horizontal support plate with bolts. A slider 15 is provided on the motion track, which can move back and forth along the motion track. The movement of the slider in conjunction with the track can improve the stability of the moving object under heavy load. The slider is provided with a horizontal T-block 16. See below. Figure 8 The horizontal T-block 16 has a lower flange 16a and an upper flange 16b, with the back sides of the two flanges on the same plane. The width and height of the lower flange are smaller than those of the upper flange. A web 16c is vertically distributed between the lower and upper flanges, and a T-shaped notch 16d is provided at one end of each web. This T-shaped notch can better hold force and prevent the connector from detaching. This horizontal T-block can improve lateral force resistance and prevent the slider from detaching from the track. The horizontal T-block is equipped with a rack 29 that meshes with the drive gear. The length of the rack is shorter than the length of the horizontal T-block. A drive device 30 is mounted on one end of the horizontal support plate via a cylinder mounting seat. The drive device includes, but is not limited to, a linear drive cylinder. The drive device can drive the rack to move, which in turn drives the drive gear to rotate, ultimately realizing the rotation of the disc assembly and thus achieving the overall tilting action of the tooling equipment. The linear drive cylinder is connected to the horizontal T-block. The components on the left frame enable the active movement of the left-side disc assembly, while the right frame is driven. The right frame is equipped with a right bearing seat 9, which mounts another disc assembly connected to the tooling frame structure (i.e., Figure 1 The right bearing housing is equipped with a right bearing housing adjustment device 11, which works on the same principle as the left bearing housing adjustment device, and will not be described in detail here.

[0108] See Figure 2-3 As shown, a first stop block 17 and a second stop block 18 with an included angle of 90 degrees are provided on the outer side of the disc assembly near the left bearing housing. These two stop blocks allow the entire tooling fixture to buffer and stop during two working operations, preventing instability such as wobbling. Stop buffer assemblies are symmetrically arranged along the left bearing housing on the left frame. Figure 2 As can be seen, the stop and buffer components are the first stop and buffer component R1 and the second stop and buffer component R2. These two sets of stop and buffer components are located at the two ends of the frame (i.e., on both sides of the left disc assembly). Each stop and buffer component includes a Z-shaped support 19, a rotary cylinder 20, a C-shaped arm 21, an L-shaped upper pressure block 22, a middle pressure block 23, an L-shaped lower pressure block 24, a buffer device mounting base 25, a buffer device 26, and a stop top block 27. These components achieve both stopping and buffering effects, preventing damage to the equipment and the associated risk of loss of control. The Z-shaped support 19 is located at the end of the left frame, allowing the rotary cylinder to be suspended without occupying space. The rotary cylinder 20 is suspended at the head of the Z-shaped support. (See [reference]). Figure 3-4 The rotary cylinder is connected to a C-shaped arm 21, which is connected to an L-shaped upper pressure block 22 of the pressure head assembly. The L-shaped upper pressure block is connected to a middle pressure block 23 of the pressure head assembly, and the middle pressure block is connected to an L-shaped lower pressure block 24 of the pressure head assembly. The L-shaped lower pressure block presses against the stop surface of the corresponding stop block in different working states. When in the stop rotation state, the tooling fixture will not rotate in any direction, and the stationary state remains stable. Meanwhile, a buffer device mounting base 25 is provided on the inner side of the left frame near the Z-shaped support. The buffer device mounting base is equipped with a buffer device 26 that cooperates with the stop block, such as a buffer rod assembly with a buffer spring. The buffer device mounting base 25 is equipped with a stop top block 27 that cooperates with the stop block. It is worth mentioning that the buffer device here allows the stop block to press down on the buffer rod assembly and slowly stop, while the stop top block 27 plays a rigid stopping and limiting role. At this time, the corresponding rigid stopping mechanism of the stop block is in rigid contact with it to complete the positioning and stopping of the disc assembly in the clockwise direction, while the counterclockwise direction is achieved by relying on the stop block to achieve positioning and stopping.

[0109] See Figure 5-6In the linear gear-driven flipping clamp mechanism provided by this invention, both the first stop block and the second stop block have a square block 17-18a connected to the disc body of the disc assembly, which can, for example, enable bolt connection between the two. The square block 17-18a is vertically connected to the rectangular block 17-18b. This large-head structure is perpendicular to the square block 17-18a, which facilitates lateral stopping. The height of the rectangular block is less than that of the square block. The rectangular block has a flat stop surface 17-18c and a flat buffer surface 17-18d. A hard buffer block 17-18e is provided near the step formed by the rectangular block and the square block on the buffer surface. This hard buffer block 17-18e cooperates with the stop top block 27 for stopping and positioning. The lower part of the hard buffer block is V-shaped or C-shaped to reduce the contact area between the two.

[0110] The tilting clamp mechanism driven by linear gears provided in this invention requires adjustment of the bearing housing's position in the X and Y axes. (See [link to relevant documentation]). Figure 7 Both the left and right bearing housing adjustment devices have symmetrically distributed end adjustment pads 10-11a on the bearing housing. These square metal end adjustment pads are bolted to the frame. There is a gap 'a' between the end adjustment pads 10-11a and the bearing housing, with 'a' being 3-5 cm. Side adjustment pads 10-11b are symmetrically distributed on the sides of the bearing housing, perpendicular to the end adjustment pads. These three pads form a protective space for the bearing housing to be placed, and the upper surface of the frame supports the bearing housing. The end adjustment pads are equipped with end adjustment bolts 10-11c, which, by tightening or loosening, adjust the bearing housing's position in the X-axis direction, maximizing installation accuracy and extending the equipment's lifespan and stability. The side adjustment pads are vertically mounted with side adjustment bolts 10-11d, which adjust the bearing housing's position in the Y-axis direction. Alternatively, a side adjustment bolt can be installed on only one side adjustment pad to improve adjustment efficiency.

[0111] See Figure 9The suspension ear assembly has four quick-locking mechanisms 28, which assist in replacing the tooling fixture itself. Due to the use of a strip-type docking structure and a pre-positioning followed by locking installation method, the double-safety fixing mode improves the stability and reliability of the tooling fixture installation, preventing safety accidents during installation. Specifically, the quick-locking mechanism includes a horizontal locking strip 28-1 located on the upper semicircle of the inner side of the disc assembly. This horizontal locking strip not only provides torsional resistance to the disc structure, but also, due to its long strip shape and surface contact, increases the contact area between the docking mechanisms, distributing the stress surface and reducing damage to the disc structure caused by local overload. The disc assembly has a rectangular inner groove, which improves the overall effect of the horizontal locking strip and the disc assembly. After the horizontal locking strip and the disc assembly are locked with bolts, the sidewall of the groove disperses the force on the horizontal locking strip during torsion. See [link to relevant documentation]. Figure 10 The horizontal locking strip is bolted to the disc assembly. Symmetrical rectangular notches 28-2 are located at both ends of the horizontal locking strip, allowing flat bolt heads to be quickly inserted without deflection. This avoids the need for simultaneous use of tools below to prevent rotation when tightening nuts, improving installation safety. The horizontal locking strip has locking holes 28-3 passing through the two side walls of the rectangular notches. After tightening, a secondary locking structure, such as a locking pin, is inserted through these holes. This prevents the locking bolts from falling off during tooling fixture rotation, enhancing the overall structural reliability. A D-shaped positioning hole 28-5 is provided in the middle of the horizontal locking bar. This D-shaped positioning hole 28-5 can accommodate a D-shaped insert block structure (not shown in the figure). The D-shaped insert block structure has bolt holes for mates with bolts. The secondary insertion of the D-shaped insert block structure ensures that it will not deflect. The different bolt holes within it avoid the problem of mismatch when assembling bolts with different outer diameters. More importantly, this D-shaped insert block structure can indirectly transmit force, improving the wedge strength with the positioning bolt and preventing the risk of breakage due to excessive displacement. Symmetrically distributed on both sides of the D-shaped positioning hole are excess positioning holes 28-6. Inserting corresponding bolts at these locations can improve the structural strength. Correspondingly, the suspension ear assembly 4 in this embodiment has an ear stacking block 4-1 that overlaps the horizontal locking bar. The two achieve surface contact, increasing the contact area to distribute the weight of the tooling fixture and prevent overload of the suspension ear assembly, which could lead to structural instability. The ear-shaped overlapping block is provided with an ear-shaped overlapping block notch 4-2 that mates with the rectangular notch. After the horizontal locking strip overlaps with the ear-shaped overlapping block, a positioning and tightening bolt assembly 28-4 is provided at the rectangular notch and the ear-shaped overlapping block notch. The upper part of the positioning and tightening bolt assembly 28-4 uses a lock nut and a washer to achieve a tightening effect. Here, the positioning and tightening bolt assembly mainly serves a positioning function, and during the initial assembly process, the working fixture is in a position where... Figure 1 In the horizontal position, the positioning set bolt assembly has a square head that matches the rectangular notch to prevent the set bolt from deflecting. After the two pressure blocks are positioned and fixed by the washer and nut, the square head is provided with a through hole that matches the locking hole. A secondary locking pin is installed in this through hole and the locking hole. The secondary locking pin provides a secondary safety and fixation effect for the positioning set bolt assembly. The ear stacking block 4-1 is provided with an upper positioning hole 4-3 that matches the D-shaped middle positioning hole. The ear stacking block has upper allowance positioning holes 4-4 symmetrically distributed on both sides of the upper positioning hole. The edge of the upper positioning hole is provided with a positioning bolt fixing screw hole 4-5. A middle positioning bolt 28-7 is provided at the upper positioning hole and the D-shaped middle positioning hole. The head of the middle positioning bolt 28-7 can be fixed to the positioning bolt fixing screw hole 4-5 by two screws to improve its own fixing stability.

[0112] The detailed structure of each clamping unit is described in detail below.

[0113] Before describing the clamping unit 5 of the reinforcing component assembly, let's briefly describe the reinforcing component assembly 1 that needs to be press-fitted, see [link to relevant documentation]. Figure 33 The reinforcing component P1 has a front protrusion P1-1, a web P1-2, a left side plate P1-3, a right side plate P1-4, and a rear side plate P1-5. The rear side plate P1-5 is welded to the left side plate P1-3 and the right side plate P1-4, respectively, at the right folded edge P1-3-1 and left folded edge P1-4-1 of the left side plate and right side plate, respectively. The web P1-2 has a central hole P1-2-1. Two rear openings P1-2-2 are located near the rear side plate P1-5 on the web P1-2. The upper and front edges of both the left side plate P1-3 and the right side plate P1-4 have folded edges. Figure 33 The text provides the solder joint position X of the reinforcing component assembly one, where the solder joint X is located at the junction with... Figure 1 When the tooling fixture shown is in a horizontal position, it is used in conjunction with the welding machine to complete the welding operation (the weld points of the parts on the horizontal plane parallel to the base plate of the tooling are...). Figure 1 Welding is performed in the horizontal position shown by using a welding torch, and the weld points on the part on the plane perpendicular to the tooling base plate are... Figure 1 Welding is performed after the state shown is flipped 90 degrees.

[0114] See Figure 12The present invention provides a linear gear-driven flipping clamping mechanism, in which the reinforcing component assembly—clamping unit 5—includes a first L-shaped base 5-1, a first irregularly shaped support plate 5-2, a first driving cylinder 5-3, a web pressing assembly 5-4, and a first support assembly 5-5. The first L-shaped base 5-1, bolted to the horizontal U-shaped plate, includes a horizontal base plate fixed to the horizontal U-shaped plate and a vertical plate welded to it. Both are vertically installed and equipped with triangular reinforcing ribs. The entire first L-shaped base 5-1 is located near the right end longitudinal beam and rear cross beam corner of the rectangular frame 3-1. The first irregularly shaped support plate 5-2 is laterally fixed to the first L-shaped base. The first irregularly shaped support plate 5-2 and the vertical plate of the first L-shaped base are not on the same vertical plane; this staggered distribution improves space utilization efficiency, and the bolted fixing facilitates disassembly, installation, and maintenance. (See also...) Figure 13 The first irregularly shaped support plate 5-2 has a gun-shaped support part 5-2a. The spine of the gun-shaped support part 5-2a can serve as a support for fixing the corresponding structure. The tail of the gun-shaped support part 5-2a is provided with an upper protrusion plate 5-2b and a tail protrusion suspension part 5-2c. The upper protrusion plate 5-2b can be equipped with positioning guides and other structures as needed to improve the stability of long parts under cylinder drive. The first drive cylinder 5-3 is vertically installed at the tail protrusion suspension part 5-2c. The first drive cylinder 5-3 serves as the power part of the clamping unit of the reinforcing component assembly 1 to complete the pressing action. The first drive cylinder 5-3 is connected to the control module and is connected to the pressing assembly 5-4 on the web of the reinforcing component assembly 1. The tail of the pressing assembly on the web is connected to the first drive cylinder 5-3 through a rotating shaft assembly. As the first drive cylinder 5-3 extends and retracts, the reinforcing component assembly 1 is pressed. After the welding action is completed, the reinforcing component assembly 1 can be removed by opening the pressing assembly 5-4 on the web. See also Figure 14 The pressing assembly 5-4 on the web of the reinforcing component assembly one includes: a first upper pressing drive arm 5-4a connected to the first drive cylinder via a connecting seat; a first upper abdominal block 5-4b disposed on the abdomen of the first upper pressing drive arm 5-4a; a first L-shaped lower pressing block 5-4c disposed on the first upper abdominal block and symmetrically distributed; a first L-shaped front adapter block 5-4d disposed at the front end of the first upper pressing drive arm; and a first front pressing head 5-4e disposed on the first L-shaped front adapter block. The backs of the two first L-shaped lower pressing blocks 5-4c are fixed to the first upper pressing drive arm 5-4a via a first upper abdominal block 5-4b to achieve synchronous pressing action. The two first L-shaped lower pressing blocks 5-4c are fitted and pressed into the position where the front protrusion P1-1 of the reinforcing component assembly one is connected to the front edge of the web of the reinforcing component assembly one through a point structure adaptation. By pressing the upper surface of the front edge of the web of the reinforcing component assembly one, the reinforcing component assembly one is prevented from moving in the height direction of the tooling fixture. Figure 1 (The vertical direction is the height direction). See also Figure 17The first front pressure head 5-4e has a first front pressure head fixing seat 5-4e-1 connected to the first L-shaped front adapter block, a first front pressure head bottom pressure block 5-4e-2 disposed on the first front pressure head fixing seat (for pressing the surface of the rear part of the web plate P1-2 of the reinforcing component assembly), and a first front pressure head side pressure block 5-4e-3 disposed on the first front pressure head fixing seat (for pressing the inner side of the rear side plate P1-5 of the reinforcing component assembly). The upper protruding plate 5-2b is equipped with a guide positioning block 5-2b-1 and a positioning guide clamping plate 5-2b-2 that cooperate with the first upper pressing drive arm. The guide positioning block 5-2b-1 is a block-shaped body with a trapezoidal upper cross section, while the positioning guide clamping plate 5-2b-2 is a plate-shaped component arranged opposite to it. The gap between the oppositely arranged plate-shaped components is used to achieve lateral limiting and guidance of the upper pressing drive arm during the opening and closing process. The first upper pressing drive arm 5-4a is equipped with a belly pressure guide head 5-4f that cooperates with the guide positioning block 5-2b-1 and has a trapezoidal groove at the bottom. This mutual guiding structure can provide a better guiding effect during the falling process of the upper pressing drive arm.

[0115] See also Figure 12 as well as Figure 15-16 The first support component 5-5, mounted on the first irregular-shaped support plate, provides good support for the entire reinforcement assembly. When used in conjunction with the pressing component, it can fix the reinforcement assembly on a tooling fixture. The first support component 5-5 includes a first T-shaped block 5-5a mounted on the spine of the gun-shaped support section; two opposing first L-shaped upper support blocks 5-5b mounted on the first T-shaped block and cooperating with the first L-shaped pressing block (acting to press against the lower surface of the front edge of the web of the reinforcement assembly); Y-shaped side tops 5-5c symmetrically mounted on the gun-shaped support section 5-2a (acting to press against the outer surfaces of the left and right side plates of the reinforcement assembly P1); a positioning post mounting seat 5-5d mounted on the gun-shaped support section 5-2a; and positioning posts 5-5e mounted on the positioning post mounting seat (acting to press against the two rear... The structure includes a fixed effect of the opening and fitting, a first side top block 5-5f set on the end face of the gun-type bearing part 5-2a (which serves to press against the outer side of the rear side plate of the reinforcing component assembly 1 P1), and a rear top block 5-5g of the web plate of the reinforcing component assembly 1 set on the spine of the gun-type bearing part 5-2a and distributed near the first side top block. The rear top block 5-5g of the web plate of the reinforcing component assembly 1 presses against the lower surface of the web plate of the reinforcing component assembly 1 between the rear openings P1-2-2 of the two web plates of the reinforcing component assembly 1. With the above structure, the reinforcing component assembly 1 can be positioned and fixed on the tooling fixture in a relatively convenient way, and it is also convenient to open and remove the welded reinforcing component assembly 1.

[0116] Before describing the floor beam assembly clamping unit 6, let's briefly describe the structure of the floor beam assembly. See [link to relevant documentation]. Figure 34The floor beam assembly includes a U-shaped main body P2-1, a first side wing P2-2, a second side wing P2-3, and a third side wing P2-4. It should be noted that an inner support component P2-5 is welded into the groove of the main body P2-1; the weld point X is shown in the figure.

[0117] See Figure 18 The floor beam assembly clamping unit 6 provided by this invention, which employs a linear gear-driven flipping clamping mechanism, includes: a floor beam assembly main body clamping portion 6-1, a floor beam assembly side wing one clamping portion 6-2, a floor beam assembly side wing two clamping portion 6-3, and a floor beam assembly side wing three clamping portion 6-4. Figure 18 The following components are specified: floor beam assembly main body P2-1, floor beam assembly side wing one P2-2, floor beam assembly side wing two P2-3, and floor beam assembly side wing three P2-4. Floor beam assembly side wing one P2-2, floor beam assembly side wing two P2-3, and floor beam assembly side wing three P2-4 need to be welded to the side plate of the floor beam assembly main body. (See also...) Figure 19 The main clamping part 6-1 of the floor beam assembly includes a right base 6-1a of the main body of the floor beam assembly, which is set on the middle strip plate. The right base 6-1a of the main body of the floor beam assembly has a stepped top and a right protruding tail. A suspended second drive cylinder 6-1b is installed on the right protruding tail. The suspension structure greatly reduces the space occupied by the second drive cylinder in the entire clamping fixture. The second upper pressing drive arm 6-1c is connected to the second drive cylinder. The second upper pressing drive arm 6-1c is equipped with a second abdominal guide block 6-1c-1. When the second upper pressing drive arm 6-1c is pressed down, it can both guide and buffer. The upper step of the right base 6-1a of the floor beam assembly body is equipped with a second lower guide block 6-1a-1 that cooperates with the second abdominal guide block 6-1c-1, and a second limiting clamp 6-1a-2 that limits the second upper pressing drive arm 6-1c. The second limiting clamp 6-1a-2 can prevent the second upper pressing drive arm 6-1c from being offset to the left or right, greatly improving the stability of the movement of the second upper pressing drive arm 6-1c, improving work efficiency, and avoiding displacement during the movement process that would affect the fixing effect on the workpiece.

[0118] See also Figure 19 The Z-shaped second pressure block 6-1d, located at the front end of the second upper pressing drive arm 6-1c, can press down on the right folded edge of the floor beam assembly body. See [link / reference]. Figure 20The diagram shows the Z-shaped second pressure block from another direction. The tail of the Z-shaped second pressure block 6-1d has a bent section 6-1d-1 at the rear of the floor beam assembly body. The bent section 6-1d-1 has a lower pressure block 6-1d-2 at the right end of the rear edge of the floor beam assembly body. The web of the Z-shaped second pressure block 6-1d has two L-shaped lower pressure blocks 6-1d-3 at the right end of the front edge of the floor beam assembly body. The workpiece (referring to the floor beam assembly body) can be removed or pressed by raising or lowering the second upper pressing drive arm 6-1c.

[0119] exist Figure 19 As can be seen, the second T-shaped block 6-1e, located on the lower step of the right base 6-1a of the floor beam assembly, achieves a fixed support structure by cantilevering two cantilever arms, efficiently utilizing the height space of the clamp. The outer cantilever of the second T-shaped block 6-1e is equipped with an upper top block 6-1e-1 on the right end of the rear folded edge of the floor beam assembly body, which cooperates with the lower pressure block 6-1d-2 on the right end of the rear folded edge of the floor beam assembly body. The inner cantilever of the second T-shaped block 6-1e is equipped with an upper top block 6-1e-2 on the right end of the front folded edge of the floor beam assembly body, which cooperates with the lower pressure block on the right end of the front folded edge of the floor beam assembly body. Figure 19 The right side floor beam assembly body front folded edge right end pressure block 6-1d-3 is used to press the parts.

[0120] See Figure 20-21 A second positioning post assembly seat 6-1f is installed on the right base 6-1a of the main body of the floor beam assembly. The second positioning post assembly seat 6-1f is provided with a second positioning post 6-1f-1 that mates with the right end hole of the web plate of the main body of the floor beam assembly. The second positioning post 6-1f-1 can provide good positioning and fixation for the main body of the floor beam assembly. The top of the second positioning post 6-1f-1 is conical, which can better facilitate the movement of falling objects.

[0121] See Figure 22The left base 6-1g of the floor beam assembly body, located at the left end of the left working plate, serves as the bottom mounting structure for the left-side fixing structure of the floor beam assembly body. The left base 6-1g has a stepped top and a left protruding tail. A third drive cylinder 6-1h is mounted on the left protruding tail, serving as the power device for lifting or pressing down the left end fixing structure of the floor beam assembly body. The third upper pressing drive arm 6-1i, connected to the third drive cylinder, is equipped with a third abdominal guide block 6-1i-1. The upper stepped portion of the left base 6-1g of the floor beam assembly body is equipped with a third lower guide block 6-1g-1 that mates with the third abdominal guide block 6-1i-1, and a third limiting clamp 6-1g-2 that limits the movement of the third upper pressing drive arm 6-1i. The aforementioned structure serves to guide and buffer the third upper pressing drive arm 6-1i, as well as prevent lateral displacement, providing reliable and stable support for the efficient movement of the third upper pressing drive arm 6-1i. The head of the 7-shaped pressure head 6-1j, located at the front end of the third upper pressing drive arm 6-1i, has two lower pressure blocks 6-1j-1 at the left end of the front folded edge of the floor beam assembly body, and at the tail of the 7-shaped pressure head, there is a lower pressure block 6-1j-2 at the left end of the rear folded edge of the floor beam assembly body. The third T-block 6-1k, located at the lower step of the left base of the main body of the floor beam assembly, can be fixed to the corresponding support structure via two cantilever arms. The third T-block 6-1k is equipped with a top block 1-k-1 at the left end of the rear fold of the main body of the floor beam assembly, which mates with the lower pressure block 6-1j-1 at the left end of the front fold of the main body of the floor beam assembly. The rear cantilever of the third T-block 6-1k is equipped with a top block 6-1k-2 at the left end of the rear fold of the main body of the floor beam assembly, which mates with the lower pressure block 6-1j-2 at the left end of the rear fold of the main body of the floor beam assembly. See [link / reference needed]. Figure 23 The third T-block 6-1k is provided with a hole P2-1-1 on the left side of the web of the main body of the floor beam assembly. Figure 34 The L-shaped positioning rod 6-1k-3 (shown in the image) mates with this hole. The state of the top of the L-shaped positioning rod 6-1k-3 passing through the leftmost hole P2-1-1 in the web of the main body of the floor beam assembly can be seen in [reference needed]. Figure 34 This design improves part positioning and avoids issues such as part scrap due to welding errors. It is located on the left working plate and is connected to the left second hole P2-1-2 of the main web of the floor beam assembly (in...). Figure 34 The lifting positioning column assembly 6-1l, which matches the hole shown in the image, can accurately position the second hole on the left side of the web plate of the main body of the floor beam assembly. The lifting positioning column assembly 6-1l uses a lifting cylinder to drive a positioning column to achieve the positioning operation required with the second hole on the left side of the web plate of the main body of the floor beam assembly. Figure 34This shows the effect of the positioning post passing through the left second hole P2-1-2 in the web of the main body of the floor beam assembly. The top of the positioning post is conical. See also Figure 24 In the linear gear-driven flipping clamp mechanism provided by this invention, the clamping part 6-2 of the floor beam assembly side wing includes a floor beam assembly side wing support base 6-2a disposed on the left working plate. The floor beam assembly side wing support base 6-2a has a stepped top and a left protruding tail. A drive cylinder 6-2b is mounted on the left protruding tail. The upper pressing drive arm 6-2c connected to the drive cylinder 6-2b achieves the pressing and fixing effect on the floor beam assembly side wing. The upper pressing drive arm 6-2c has a Y-shaped pressure head 6-2c-1. The front part of the Y-shaped pressure head is provided with two floor beam assembly side wing web plate rear pressure blocks 6-2c-2, and the rear part of the Y-shaped pressure head is provided with a floor beam assembly side wing web plate front pressure block 6-2c-3 (see...). Figure 25 See also Figure 26 The lower step of the support base 6-2a of the side wing of the floor beam assembly is equipped with a Y-shaped suspension block 6-2d. The front of the Y-shaped suspension block has two front top blocks 6-2d-1 that mate with the rear pressure block 6-2c-2 of the web of the side wing of the floor beam assembly. The tail of the Y-shaped suspension block 6-2d has a front top block 6-2d-3 that mates with the front pressure block 6-2c-3 of the web of the side wing of the floor beam assembly. These components allow for the positioning and fixation of the side wing of the floor beam assembly on a fixture, ready for subsequent welding processes.

[0122] In addition, lifting floor beam assembly side wing web front top block 6-2d-3 is installed on both sides of the floor beam assembly side wing web positioning rod assembly 6-2e, which uses a cylinder to drive the positioning rod to cooperate with the openings in the floor beam assembly side wing web to achieve the positioning and fixing effect. Figure 34 As can be seen from the image, there are openings in the side wing of the floor beam assembly and positioning rods located at the openings. The base of the positioning rod assembly for the side wing of the lifting floor beam assembly is fixed to the support base 6-2a of the side wing of the floor beam assembly. The positioning rod assembly for the side wing of the lifting floor beam assembly includes a cylinder fixed to the base of the positioning rod assembly for the side wing of the lifting floor beam assembly, a lifting platform 6-2e-1 set in the cylinder, symmetrically arranged lifting blocks 6-2e-2 on the side of the lifting platform, and positioning posts 6-2e-3 for the openings in the side wing of the floor beam assembly set in the lifting blocks (see [reference]). Figure 27 ).

[0123] See Figure 28The second clamping part 6-3 of the floor beam assembly side wing includes a first suspension support base 6-3a located at the cutout of the left working plate. A second drive cylinder 6-3b is mounted on the first suspension support base 6-3a. The upper top block assembly 6-3c on the left side of the second floor beam assembly side wing, located on the second drive cylinder, performs the top support function on the left side of the second floor beam assembly side wing. See [link / reference]. Figure 29 The upper left side block assembly 6-3c of the second side wing of the floor beam assembly is equipped with a positioning post 6-3c-1 that mates with the opening on the left side of the second side wing of the floor beam assembly; a T-shaped support 6-3c-2 mounted on the lower left side surface of the second side wing of the floor beam assembly; a Y-shaped support 6-3c-3 mounted on the lower left side surface of the second side wing of the floor beam assembly; and an upward-facing Z-shaped support 6-3c-4 mounted in the middle of the second side wing of the floor beam assembly. This structure provides support for the second side wing of the floor beam assembly. (Continue to see...) Figure 28 A second suspension support base 6-3d is installed at the cutout of the left working plate. A third drive cylinder 6-3e is installed on the second suspension support base 6-3d. An upper top block assembly 6-3f is located on the right side of the second side wing of the floor beam assembly of the third drive cylinder. This assembly includes a Z-shaped plate positioning head 6-3f-1, a central columnar support platform 6-3f-2 supported on the Z-shaped plate, and a rear support platform 6-3f-3 supported on the Z-shaped plate (see...). Figure 30 The Z-shaped plate P2-3-1 can be welded and fixed to the lower surface of the right side of the second side wing of the floor beam assembly through the above structure, and the Z-shaped plate extends to the web of the first reinforcing component for welding and fixing. In addition, the second Z-shaped pressure block is provided with a lower pressure block 6-3g of the second side wing of the floor beam assembly that presses down on the upper surface of the second side wing of the floor beam assembly and cooperates with the upper top block component on the right side of the second side wing of the floor beam assembly. Here, the pressing action is cleverly accomplished by using the existing cylinder structure (i.e., the pressing cylinder at the right end of the main body of the floor beam assembly; unless otherwise specified, the pressing cylinder used in this case is a rotary cylinder).

[0124] See Figure 31 The floor beam assembly side wing three clamping part 6-4 includes a floor beam assembly side wing three support base 6-4a located on the front side of the middle strip plate. The drive cylinder four 6-4b located on the floor beam assembly side wing three support base 6-4a serves as the power device for supporting the floor beam assembly side wing three. See Figure 32 The floor beam assembly side wing three upper block assembly 6-4c, which is located on the drive cylinder four, includes a front top block 6-4c-1 of the floor beam assembly side wing three and a rear top block 6-4c-3 mounted on the floor beam assembly side wing three. The front top block of the floor beam assembly side wing three is provided with a positioning post 6-4c-2 of the floor beam assembly side wing three, and the upper surface of the floor beam assembly side wing three is pressed against the front folded edge of the reinforcing member assembly one.

[0125] This invention uses a PLC as the control module, which is connected to each working cylinder. After welding a 0-degree weld point, the PLC system sends instructions to the relevant cylinders to rotate the welding fixture 90 degrees via a linear guide, thus completing the 90-degree weld point.

[0126] Example 2: This example is an improvement on Example 1. Because the first and second stop blocks are horizontally offset structures, the areas where the stop blocks are fixed by bolts are relatively thin. Long-term rigid impacts can easily lead to stress concentration and structural damage. Therefore, see [reference needed]. Figures 35-36 The L-shaped pressing block 24 includes a vertical head 24-1 and a horizontal body 24-2. The vertical head 24-1 and the horizontal body 24-2 adopt a separate elastic structure. The separate elastic structure can not only help improve the flexibility of the L-shaped pressing block itself, but more importantly, it can reduce the stress concentration damage caused by rigid collisions. The horizontal body of the L-shaped pressing block is provided with four guide shafts 24-3. The horizontal body is generally a rectangular block. The guide shafts 24-3 can be arranged in a two-row, two-column pattern on the right end of the horizontal body. The four guide shafts can improve the stability of operation. Each guide shaft is fitted with a guide spring 24-4, and the external part of the guide spring 24-4 is also limited by the guide spring mounting holes provided in the horizontal body. The lower part of the guide spring is connected to a lower spring-type guide rod 24-5 that can extend into the vertical head. The guide spring can suspend the lower spring-type guide rod directly below the guide shaft. The bottom of the lower spring-type guide rod has a T-shaped head 24-5a. This T-shaped head can ensure that the vertical head and the horizontal body in the split elastic structure are elastically connected. The vertical head is provided with a T-shaped hole that mates with the lower spring-type guide rod. The vertical head can be provided with an inverted T-shaped insertion groove that extends from the side wall of the vertical head to the T-shaped hole. This allows the T-shaped head structure to slide into the mounting hole of the lower spring-type guide rod from the inverted T-shaped insertion groove.

[0127] It is worth mentioning that the guide shaft is axially provided with a labyrinth-type vent hole 24-3a, and the bottom of the guide shaft is axially provided with a spring-loaded hole 34-3b. The top outer diameter of the lower spring-loaded guide rod matches the spring-loaded hole, and the labyrinth-type vent hole communicates with the spring-loaded hole. Since the top of the lower spring-loaded guide rod 24-5 is fitted with a spring-loaded hole, when the axial protrusion (which is located at the top of the lower spring-loaded guide rod and whose outer diameter matches the spring-loaded hole, and can be a circular rubber boss structure) enters the spring-loaded hole, it is difficult for the axial protrusion to enter and exit the spring-loaded hole because the air inside the spring-loaded hole cannot be discharged. The labyrinth-type vent hole can release the air slowly, allowing the axial protrusion to slowly enter the spring-loaded hole. The above-mentioned separate elastic structure flexibly presses the stop block, avoiding damage to the stop block from rigid collisions. At the same time, this flexible structure also protects the entire structure (rigid collisions not only easily damage the stop block, but also affect precision components such as cylinders due to long-term vibration).

[0128] Example 3: This example is an improvement on Example 1. The motion track 15 has motion track mounting holes, which are fitted with oil filler bolts to fix the motion track. Figure 37 As shown, the oil-filling bolt has a bolt body 15-a with an outer bolt. An operating port (not shown in the figure, but facilitates screwing and rotation with tools; this port may include, but is not limited to, a hexagonal operating port, refer to existing technology) is located at the top of the bolt body. A compression spring 15-b is located at the top of the compression spring, and a top ring 15-c is located at the top of the compression spring. An oil-collecting structure 15-d (which may be made of a material that absorbs lubricating oil, such as a sponge, refer to existing technology) is located between the top ring and the bolt body. In the installed state, there is a safety gap (preferably small) between the top ring and the top of the mounting hole of the motion track. A sealing ring 15-e (including, but not limited to, a rubber sealing ring, refer to existing technology) may be installed at the bolt body as needed. Tools can be used to screw the oil-filling bolt onto the motion track by passing through the compression spring (from the middle) and turning the operating port. After installation, lubricating oil is injected into the oil-filling bolt. The oil-collecting structure absorbs the lubricating oil. During daily use, when the rod presses down on the top ring, the lubricating oil at the oil-filling bolt will be squeezed out, and the overflowing oil lubricates the motion track. Because there is a safety clearance between the top ring and the top of the mounting hole in the motion track, the lubrication bolt will not affect the operation of the track. Lubrication can be added when the amount of lubricating oil at the lubrication bolt is insufficient. The lubrication bolt facilitates the use and maintenance of the motion track.
