Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and more specifically, to a rear floor clamp that can be used by multiple vehicle models. Background Technology

[0002] With the increasing penetration of new energy vehicles and the growing number of cars on the road, major automakers are updating their models more frequently to improve quality and efficiency in the manufacturing process. To quickly gain customer attention and enhance quality competitiveness, automakers are required to shorten new car development cycles while improving component quality and body-in-white precision. During the body-in-white prototyping process, the lower body is assembled from approximately 38 welded parts, such as the left and right front and rear longitudinal beams, left and right door sills, and left and right A-pillar inner panels. These parts are generally assembled into a front engine compartment assembly, a front floor assembly, and a rear floor assembly. Assembling these three assemblies together forms the lower body. For the rear floor assembly, its front part needs to connect with the front... The floor assembly connection requires the installation of rear fenders and C-pillars at the top and rear bumper beams at the rear. Controlling the height accuracy of the rear fenders and C-pillars during installation is difficult, leading to potential deviations. Furthermore, existing fixtures are generally designed for individual parts of the same vehicle model; different parts within the same model require different fixtures, and even parts in the same area across different models require different fixtures. The limited production volume of prototype body-in-white and frequent model changes further complicate the installation process during the prototyping phase, resulting in low efficiency and impacting the body-in-white prototyping schedule, ultimately failing to meet the needs of new vehicle development. Utility Model Content

[0003] To overcome the shortcomings of the prior art, such as low installation efficiency of body-in-white parts and inability to meet installation requirements, this utility model provides a rear floor clamp that can be used by multiple vehicle models. It also provides an installation reference for various parts of the rear floor assembly, thereby improving installation efficiency and accuracy.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a rear floor clamp for multiple vehicle models, comprising: a support frame, movable components respectively disposed on both sides and the rear of the support frame, side brackets and rear brackets respectively mounted on the movable ends of the movable components, mounting plates respectively adjustablely mounted on the support frame, the side brackets and the rear bracket, handles respectively mounted on both sides of the mounting plate, and clamping components, positioning components and position calibrators; the side brackets are respectively disposed on both sides of the support frame, and at least two movable components are connected to the bottom of the side brackets and the rear bracket; the mounting plate is provided with a rectangular array of multiple mounting holes, the clamping components and the positioning components are respectively mounted on the mounting plate through the mounting holes, the position calibrators are used to provide an installation reference for the clamping components and the positioning components, and the position calibrators are respectively disposed on the side brackets, the rear bracket and the four corners of the support frame.

[0005] The clamping and positioning components mounted on the support frame are used to clamp and position the parts at the bottom of the rear floor assembly. Side supports are provided on both sides of the support frame. The clamping and positioning components mounted on the side supports are used to clamp and position the fenders, C-pillars, and other parts located on the upper sides. The clamping and positioning components mounted on the rear support are used to clamp and position the rear parts of the rear floor assembly and the rear bumper. To achieve simultaneous installation of parts in various locations, both the side and rear supports are mounted on the support frame via movable components. These components can then be moved to provide installation space for the parts at the bottom of the rear floor assembly. Furthermore, to accommodate multiple vehicle models, mounting plates are installed on the support frame, side supports, and rear support. The clamping and positioning components are mounted on these mounting plates, allowing for adjustment of the clamping and positioning component positions. The mounting plates can be adjusted in various ways, such as using clamps, providing multiple mounting holes on the bottom and side supports, or using sliding grooves.

[0006] The mounting plate is equipped with multiple mounting holes arranged in a rectangular array, facilitating the determination of the installation position and further improving the adjustability and precision of the clamping and positioning components. Furthermore, a handle is provided on the mounting plate. Specifically, the mounting plate is detachably connected to the support frame, side brackets, and rear brackets. When significant differences exist between parts on different vehicle models, requiring direct replacement of the clamping and positioning components, the mounting plate can be removed along with the clamping and positioning components mounted on it. Then, the mounting plate with the required clamping and positioning components can be installed, enabling quick switching between different vehicle models. The handle facilitates the removal of the mounting plate, clamping, and positioning components together, simplifying vehicle model switching and installation. For fine-tuning the mounting plate's position, the handle can be used to pull or push the mounting plate, making operation more convenient. To ensure the accuracy of the installation positions of the clamping and positioning components, position calibration components are installed on the support frame, side brackets, and rear brackets. The position calibration components have positioning references. When this matching sample is initially assembled or the vehicle model is changed, a laser tracker is used to determine and check the installation positions of each clamping and positioning component with each position calibration component as a coordinate reference, so as to ensure installation accuracy, thereby improving the clamping and positioning accuracy of the parts and improving the installation accuracy of the rear floor assembly.

[0007] Preferably, the clamping assembly includes a first connecting rod connected to the mounting plate, a first clamping block connected to the first connecting rod, a second connecting rod connected to the first connecting rod, a second clamping block connected to the second connecting rod, and a first bolt threaded through the second clamping block and connected to the second connecting rod. Both the first clamping block and the second clamping block are provided with contoured abutment surfaces. When the first bolt is tightened, the second clamping block moves toward the first clamping block and clamps the part.

[0008] Both the first and second connecting rods serve to connect and extend. The first and second clamping blocks are working components. The second clamping block is movably connected to the second connecting rod. Under the adjustment of tightening the first bolt, the second clamping block approaches the first clamping block and clamps the part. Both the first and second clamping blocks are provided with contoured abutment surfaces. The shape of the contoured abutment surfaces is set according to the contour of the part being clamped, in order to increase the contact area and improve clamping stability.

[0009] Preferably, the clamping assembly further includes a third connecting rod connected to the mounting plate, a fourth connecting rod connected to the third connecting rod, a second bolt threaded to the fourth connecting rod, a limiting ring fitted on the fourth connecting rod, a quick clamp connected to the fourth connecting rod, and a third clamping block connected to the clamping end of the quick clamp. When the quick clamp clamps, the third clamping block moves toward the first clamping block and clamps the part.

[0010] The clamping unit also features a third clamping block for gripping. A fourth connecting rod connected to the third clamping block can be adjusted in position relative to the third connecting rod, thereby adjusting the clamping distance of the third clamping block. The fourth connecting rod is axially positioned by a limiting ring and circumferentially fixed by a second bolt. Furthermore, the third clamping block is driven by a quick-release clamp, resulting in higher clamping efficiency. Quick-release clamps are common clamping mechanisms in the mechanical field, and can be classified as horizontal or vertical clamps based on their clamping method, and as manual or automatic clamps based on their driving method, allowing for selection based on specific needs. The third clamping block also works in conjunction with the first clamping block for clamping, and is primarily used for long-distance clamping. When the part is far from the clamping position, or when there is interference between the second clamping block and the part, the third clamping block is used. In cases where the contoured contact surface of the first clamping block is large, both the second and third clamping blocks can be used simultaneously to improve clamping stability.

[0011] Preferably, the positioning component includes a first positioning element, which includes a first positioning base connected to the mounting plate, a first positioning pin slidably connected to the first positioning base longitudinally, and a first lever. The first positioning base has an L-shaped groove on its side, and the first lever passes through the L-shaped groove and connects to the first positioning pin.

[0012] In the first positioning component, the first positioning pin slides longitudinally relative to the first positioning base. It extends when the part needs to be positioned and retracts when only support is needed, in order to adapt to different models and different parts. The L-shaped groove is used to limit the extension height of the first lever and the first positioning pin and to provide high-level support for the first lever and the first positioning pin, so as to prevent the first positioning pin from falling off.

[0013] Preferably, the positioning component includes a second positioning element, which includes a second positioning base connected to the mounting plate, a second positioning pin slidably connected to the second positioning base longitudinally, a second lever, and a fixing pin. The second positioning base has a vertical groove on its side, the second lever passes through the vertical groove and is fixedly connected to the second positioning pin, and both the second positioning base and the second positioning pin have pin holes. The pin passes through the pin holes to fix the second positioning pin.

[0014] The structure of the second positioning component is similar to that of the first positioning component. In the second positioning component, the second positioning pin extends out and is fixed by a fixing pin. It is used in positions where the operating space of the second lever is narrow and there is no room for rotation.

[0015] Preferably, the second positioning component further includes a lower pressure block fitted on the second positioning pin and a third bolt, wherein the third bolt passes through the top of the lower pressure block and is threadedly connected to the second positioning pin, and the third bolt is used to fix the lower pressure block on the second positioning pin.

[0016] The pressure block is set to press down and clamp the positioning part, achieving both positioning and clamping effects. Tightening the third bolt will achieve the pressing and clamping effect.

[0017] Preferably, the movable component includes a movable bracket connected to the support frame, a slide rail assembly mounted on the movable bracket, a support plate mounted on the movable end of the slide rail assembly, a pin seat mounted on the top of the movable bracket, a first pin hole respectively provided on the movable bracket, a second pin hole provided on the pin seat, and a positioning pin slidably connected to the first pin hole. Both the first pin hole and the second pin hole are provided with bushings of the same inner diameter.

[0018] The movable bracket is fixedly mounted on the support frame. The slide rail assembly includes a slide rail and a slider, with the slide rail fixedly mounted on the movable bracket and the support plate mounted on the slider, allowing the mounting plate to move relative to the support frame. A pin seat is fixedly mounted on the top of the movable bracket, with positioning pins passing through the first and second pin holes to fix the support plate relative to the movable bracket. To ensure the accuracy of the support plate's fixed position, bushings are provided in both the first and second pin holes, with the positioning pins passing through these bushings to secure the support plate. Specifically, multiple pin seats are installed according to the required positioning position, with at least two.

[0019] Preferably, the movable bracket is provided with a protrusion, the first pin hole is provided on the protrusion, the bottom surface of the protrusion is provided with a first anti-collision slope on both sides, and the top surface of the pin seat is provided with a second anti-collision slope on both sides. The first anti-collision slope and the second anti-collision slope are used to prevent the movable bracket from colliding with the pin seat when it moves.

[0020] Both the side and tail brackets require the installation of numerous clamping and positioning components, resulting in a relatively heavy overall weight. Consequently, the side and tail brackets may undergo slight deformation, potentially causing them to collide with the pin seat during movement. Therefore, a first anti-collision ramp and a second anti-collision ramp are respectively provided on both sides of the protrusion and the pin seat to prevent collisions.

[0021] Preferably, the support frame, the side bracket, and the tail bracket are all assembled from aluminum profiles, and the bottom of the support frame is also provided with casters.

[0022] Aluminum profiles are commonly used components in modern industry. They have axial grooves on their sides. During installation, a special nut for aluminum profiles is placed into the groove, and external parts are connected to the special nut for aluminum profiles to install. This allows for adjustable installation of the mounting plate, which can be moved arbitrarily along the axis of the aluminum profile for easy position adjustment. At the same time, the bottom of the support frame is equipped with casters to facilitate the overall movement of this matching sample frame.

[0023] Preferably, both the side bracket and the tail bracket include a horizontal frame mounted on the moving end of the moving component, a vertical frame fixedly connected to the horizontal frame, and a triangular reinforcing frame disposed on the back of the vertical frame, wherein the triangular reinforcing frame is connected to the moving end of the moving component.

[0024] Both the horizontal and vertical frames can be used to install clamping and positioning components. The triangular reinforcement frame connects to both the vertical frame and the moving end of the moving component, providing lateral fixation and support for the vertical frame, preventing it from tilting and ensuring accuracy.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. Clamping and positioning components are installed on the support frame, side brackets, and rear brackets respectively to clamp and position all components of the rear floor assembly. Position calibration components are set to provide positioning references for all clamping and positioning components, ensuring the installation accuracy of each clamping and positioning component. This ensures that there is a dimensional relationship between all parts of the rear floor assembly, significantly reducing the installation error of each part, improving the overall installation accuracy of the rear floor assembly, and also improving installation efficiency.

[0027] 2. The mounting plate is detachable and has handles on both sides. When it is necessary to switch vehicle models, the mounting plate, clamping components, and positioning components can be removed together. Use the handles to remove the mounting plate and then install the mounting plate with the required clamping and positioning components. This allows for quick switching between different vehicle models and improves installation efficiency during the trial production stage. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0037] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0038] Example 1

[0039] like Figure 1 As shown, a rear floor clamp shared by multiple vehicle models includes: a support frame 1, movable components 2 respectively disposed on both sides and the rear of the support frame 1, side brackets 3 and rear brackets 4 respectively mounted on the movable ends of the movable components 2, mounting plates 5 respectively adjustablely mounted on the support frame 1, side brackets 3 and rear brackets 4, handles 6 respectively mounted on both sides of the mounting plate 5, and clamping components 7, positioning components 8 and position calibrators 9; side brackets 3 are respectively disposed on both sides of the support frame 1, and at least two movable components 2 are connected to the bottom of both the side brackets 3 and the rear bracket 4; the mounting plate 5 has a rectangular array of multiple mounting holes, and the clamping components 7 and positioning components 8 are respectively mounted on the mounting plate 5 through the mounting holes; the position calibrators 9 are used to provide an installation reference for the clamping components 7 and positioning components 8; and position calibrators 9 are respectively disposed on the side brackets 3, the rear brackets 4 and the four corners of the support frame 1.

[0040] The clamping assembly 7 and positioning assembly 8 mounted on the support frame 1 are used to clamp and position the parts at the bottom of the rear floor assembly. Side supports 3 are provided on both sides of the support frame 1. The clamping assembly 7 and positioning assembly 8 mounted on the side supports 3 are used to clamp and position the fenders, C-pillars, and other parts located on the upper sides. The clamping assembly 7 and positioning assembly 8 mounted on the rear support 4 are used to clamp and position the rear parts of the rear floor assembly and the rear bumper, etc. To achieve simultaneous installation of parts in various locations, both the side supports 3 and the rear support 4 are mounted on the support frame 1 via the moving assembly 2. Furthermore, the side brackets 3 and rear brackets 4 can be moved apart by the movable component 2 to provide installation space for the bottom parts of the rear floor assembly. At the same time, in order to adapt to multiple vehicle models, mounting plates 5 are installed on the support frame 1, side brackets 3 and rear brackets 4 respectively. Clamping components 7 and positioning components 8 are installed on the mounting plates 5 respectively, thereby realizing the adjustment of the clamping and positioning components 8. There are multiple adjustable installation methods for mounting plates 5, such as using clamp installation, or setting multiple mounting holes on the bottom bracket and side bracket, or setting sliding grooves, etc.

[0041] Multiple mounting holes are provided on the mounting plate 5 in a rectangular array, which facilitates the determination of the installation position and further improves the adjustability and precision of the clamping component 7 and the positioning component 8. In addition, a handle 6 is provided on the mounting plate 5. Specifically, the mounting plate 5 is detachably connected to the support frame 1, the side bracket 3, and the rear bracket 4. When the differences between parts of different vehicle models are too large and it is necessary to directly replace the clamping component 7 and the positioning component 8, the mounting plate 5 can be removed directly, along with the clamping component 7 and the positioning component 8 installed on the mounting plate 5. Then, the mounting plate 5 with the required clamping component 7 and the positioning component 8 can be replaced, realizing quick switching between different vehicle models. The handle 6 makes it easy to remove the mounting plate 5, the clamping component 7, and the positioning component 8 together, which is convenient for vehicle model switching and installation. When making fine adjustments to the position of the mounting plate 5, the mounting plate 5 can also be pulled or pushed by the handle 6, making the operation more convenient. To ensure the accuracy of the installation positions of the clamping components 7 and the positioning components 8, position calibration components 9 are installed on the support frame 1, the side bracket 3, and the rear bracket 4. The position calibration components 9 are equipped with positioning references. When this matching sample frame is initially assembled or the vehicle model is changed, a laser tracker is used to determine and check the installation positions of each clamping component 7 and the positioning components 8 with each position calibration component 9 as a coordinate reference, so as to ensure the installation accuracy, thereby improving the clamping and positioning accuracy of the parts and improving the installation accuracy of the rear floor assembly.

[0042] The beneficial effects of this embodiment are as follows: Clamping components 7 and positioning components 8 are installed on the support frame 1, side bracket 3, and rear bracket 4 respectively to clamp and position all components of the rear floor assembly. Position calibration components 9 provide positioning references for all clamping components 7 and positioning components 8, ensuring the installation accuracy of each clamping component 7 and positioning component 8. This ensures dimensional correlation between all parts of the rear floor assembly, significantly reducing installation errors and improving the overall installation accuracy and efficiency of the rear floor assembly. The mounting plate 5 is detachable and has handles 6 on both sides. When switching vehicle models, the mounting plate 5, clamping components 7, and positioning components 8 are removed together. The handles 6 are used to remove the mounting plate 5, and then the mounting plate 5 with the required clamping components 7 and positioning components 8 is installed, enabling rapid switching between different vehicle models and improving installation efficiency during the trial production stage.

[0043] Example 2

[0044] This embodiment further defines the features of Embodiment 1, and its difference from Embodiment 1 lies in:

[0045] like Figure 4As shown, the clamping assembly 7 includes a first connecting rod 701 connected to the mounting plate 5, a first clamping block 702 connected to the first connecting rod 701, a second connecting rod 703 connected to the first connecting rod 701, a second clamping block 704 connected to the second connecting rod 703, and a first bolt 705 threaded through the second clamping block 704 and the second connecting rod 703. The first clamping block 702 and the second clamping block 704 are respectively provided with a contoured abutment surface. When the first bolt 705 is tightened, the second clamping block 704 moves toward the first clamping block 702 and clamps the part. The clamping assembly 7 also includes a third connecting rod 706 connected to the mounting plate 5, a fourth connecting rod 707 connected to the third connecting rod 706, a second bolt 708 threadedly connected to the fourth connecting rod 707, a limiting ring 709 fitted on the fourth connecting rod 707, a quick clamp 710 connected to the fourth connecting rod 707, and a third clamping block 711 connected to the clamping end of the quick clamp 710. When the quick clamp 710 clamps, the third clamping block 711 moves toward the first clamping block 702 and clamps the part.

[0046] Both the first connecting rod 701 and the second connecting rod 703 serve to connect and extend. The first clamping block 702 and the second clamping block 704 are working parts. The second clamping block 704 is movably connected to the second connecting rod 703. Under the adjustment of tightening the first bolt 705, the second clamping block 704 approaches the first clamping block 702 and clamps the part. Both the first clamping block 702 and the second clamping block 704 are provided with contoured abutment surfaces. The shape of the contoured abutment surfaces is set according to the contour of the part being clamped, in order to increase the contact area and improve the clamping stability. The clamping unit is also equipped with a third clamping block 711 for clamping. The fourth connecting rod 707 connected to the third clamping block 711 can be adjusted in position relative to the third connecting rod 706, thereby adjusting the clamping distance of the third clamping block 711. The fourth connecting rod 707 is axially positioned by a limiting ring 709 and circumferentially fixed by a second bolt 708. In addition, the third clamping block 711 is driven by a quick clamp 710, which has higher clamping efficiency. The quick clamp 710 is a common clamping mechanism in the mechanical field. According to the clamping method, it can be divided into horizontal clamps and vertical clamps. According to the driving method, it can be divided into manual clamps or start-up clamps. The specific choice can be made according to the needs. The third clamping block 711 also works with the first clamping block 702 for clamping, and is preferentially used for long-distance clamping. When the part is clamped at a distance or when the second clamping block 704 interferes with the part, the third clamping block 711 is used for clamping. In some cases where the contour abutment surface of the first clamping block 702 is large, the second clamping block 704 and the third clamping block 711 can also be used simultaneously for clamping to improve clamping stability.

[0047] like Figure 5-6As shown, the positioning component 8 further includes a first positioning element 10, which includes a first positioning base 1001 connected to the mounting plate 5, a first positioning pin 1002 slidably connected to the first positioning base 1001 in the longitudinal direction, and a first lever 1003. The side of the first positioning base 1001 is provided with an L-shaped groove 1004, and the first lever 1003 passes through the L-shaped groove 1004 and is connected to the first positioning pin 1002. The positioning assembly 8 includes a second positioning element 11. The second positioning element 11 includes a second positioning base 1101 connected to the mounting plate 5, a second positioning pin 1102 slidably connected to the second positioning base 1101 longitudinally, a second lever 1103, and a fixing pin 1104. The second positioning base 1101 has a vertical groove 1105 on its side. The second lever 1103 passes through the vertical groove 1105 and is fixedly connected to the second positioning pin 1102. The second positioning base 1101 and the second positioning pin 1102 each have a pin hole. The pin passes through the pin hole to fix the second positioning pin 1102. The second positioning element 11 also includes a lower pressure block 1106 fitted on the second positioning pin 1102 and a third bolt 1107. The third bolt 1107 passes through the top of the lower pressure block 1106 and is threadedly connected to the second positioning pin 1102. The third bolt 1107 is used to fix the lower pressure block 1106 on the second positioning pin 1102.

[0048] In the first positioning component 10, the first positioning pin 1002 slides longitudinally relative to the first positioning base 1001. It extends when positioning the part is needed and retracts when only support is required, adapting to different vehicle models and parts. The L-shaped groove 1004 limits the extension height of the first lever 1003 and the first positioning pin 1002 and provides high-level support for the first lever 1003 and the first positioning pin 1002, preventing the first positioning pin 1002 from falling off. The structure of the second positioning component 11 is similar to that of the first positioning component 10. In the second positioning component 11, the second positioning pin 1102 is fixed by the fixing pin 1104 after extending. It is used in positions where the operating space of the second lever 1103 is narrow and there is no room for rotation. A pressure block 1106 is set to press down and clamp the positioning part, achieving both positioning and clamping effects. Tightening the third bolt 1107 achieves the pressing and clamping effect.

[0049] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0050] Example 3

[0051] Based on Example 1 or Example 2, Example 1 or Example 2 are further defined, with the following differences:

[0052] like Figure 1-3As shown, the movable component 2 includes a movable bracket 201 connected to the support frame 1, a slide rail assembly 202 mounted on the movable bracket 201, a support plate 203 mounted on the movable end of the slide rail assembly 202, a pin seat 204 mounted on the top of the movable bracket 201, a first pin hole respectively provided on the movable bracket 201, a second pin hole provided on the pin seat 204, and a positioning pin 205 slidably connected to the first pin hole. Both the first and second pin holes are respectively provided with bushings of the same inner diameter. The movable bracket 201 is provided with a protrusion 206, and the first pin hole is located on the protrusion 206. The bottom surface of the protrusion 206 has first anti-collision inclined surfaces 207 on both sides, and the top surface of the pin seat 204 has second anti-collision inclined surfaces 208 on both sides. The first and second anti-collision inclined surfaces 207 and 208 are used to prevent the movable bracket 201 from colliding with the pin seat 204 when it moves. The support frame 1, side bracket 3, and tail bracket 4 are all assembled from aluminum profiles, and the support frame 1 is also equipped with casters 12 at the bottom. The side bracket 3 and tail bracket 4 each include a horizontal frame 13 installed on the moving end of the moving component 2, a vertical frame 14 fixedly connected to the horizontal frame 13, and a triangular reinforcing frame 15 set on the back of the vertical frame 14. The triangular reinforcing frame 15 is connected to the moving end of the moving component 2.

[0053] The movable bracket 201 is fixedly mounted on the support frame 1. The slide rail assembly 202 includes a slide rail and a slider, wherein the slide rail is fixedly mounted on the movable bracket 201, and the support plate 203 is mounted on the slider, allowing the mounting plate 5 to move relative to the support frame 1. The pin seat 204 is fixedly mounted on the top of the movable bracket 201. The positioning pin 205 passes through the first pin hole and the second pin hole, fixing the support plate 203 relative to the movable bracket 201. Simultaneously, to ensure the accuracy of the fixed position of the support plate 203, bushings are provided in both the first and second pin holes, and the positioning pins 205 pass through the bushings to fix the support plate 203. Specifically, multiple pin seats 204 are installed according to the required positioning position, with at least two. Both the side bracket 3 and the tail bracket 4 require the installation of numerous clamping components 7 and positioning components 8, resulting in a relatively heavy overall weight. Therefore, the side bracket 3 and tail bracket 4 may undergo slight deformation, potentially colliding with the pin seat 204 during movement. To prevent this, a first anti-collision ramp 207 and a second anti-collision ramp 208 are respectively provided on both sides of the protrusion 206 and the pin seat 204. Aluminum profiles are commonly used components in modern industry. They have axial grooves on their sides. During installation, a special nut for the aluminum profile is placed into the groove, and the external parts are connected to the special nut for installation. This allows for adjustable installation of the mounting plate 5, enabling it to move freely along the aluminum profile axis for easy position adjustment. Simultaneously, the bottom of the support frame 1 is equipped with casters 12 for convenient overall movement of the matching sample frame. Both the horizontal frame 13 and the vertical frame 14 can be used to install the clamping assembly 7 and the positioning assembly 8. The triangular reinforcing frame 15 connects the vertical frame 14 and the moving end of the moving assembly 2, providing lateral fixation and support for the vertical frame 14, preventing the vertical frame 14 from tilting and ensuring accuracy.
