Description

Technical Field

[0001] This utility model belongs to the field of vehicle parts production and connecting fixture technology, and particularly relates to a T-shaped fixture block. Background Technology

[0002] As a complex structural unit, the manufacture of an automobile body requires the precise connection of hundreds of stamped parts through processes such as FDS (Fused Self-Drilling), riveting, spot welding, and projection welding. With increasingly fierce technological competition in the automotive manufacturing industry, the industry's demands for body design precision and production efficiency continue to rise. Fixtures, as core tools for fixing and positioning components in vehicle production, must not only ensure the accuracy and consistency of the manufacturing and assembly processes but also help workpieces maintain the correct position throughout the manufacturing process through reliable positioning and clamping mechanisms. This ensures product quality, improves labor productivity, and reduces the labor intensity of operators. Among these processes, FDS joining technology has become an indispensable key process for connecting body parts due to its high single-sided operation efficiency, compatibility with a wide range of materials, high connection strength, good shock resistance, and clean, debris-free working environment.

[0003] However, in actual production, the characteristics of the FDS connection process present many challenges to existing fixtures: On the one hand, the operating pressure of FDS equipment can reach more than 3500N, which cannot be operated by hand and needs to be coordinated with robots. This requires the fixture and the connected parts to have sufficient support and strength. However, traditional fixtures mostly use triangular seats or conventional angle irons as support components. The support surface of the triangular seat is not complete and the support force is unbalanced. Under high pressure, it is easy to cause the parts to bend and deform. Conventional angle irons often block the screw position and interfere with the FDS connection operation. On the other hand, traditional support components lack a dedicated X-axis positioning design, relying solely on friction on the support surface to limit component displacement. During FDS high-pressure operation, components are prone to shifting or deviating along the X-axis, affecting connection accuracy. Furthermore, a single support component provides insufficient support when subjected to the lateral force of FDS high pressure, making it difficult to effectively resist bending caused by lateral forces. Additionally, some fixtures use multiple sets of bolts to connect support components, resulting in time-consuming assembly and disassembly, and the bolts are prone to loosening due to equipment vibration, leading to support misalignment. Therefore, we propose a T-shaped fixture block. Utility Model Content

[0004] The purpose of this utility model is to provide a T-shaped clamp block to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a T-shaped clamp block, comprising: The operating table has a U-shaped structure. Multiple sets of evenly distributed triangular support brackets are symmetrically fixed to the inner wall of the operating table. A square iron block is fixed to the upper surface of the triangular support bracket by bolts. A support plate is set directly above the square iron block. The support plate has an T-shaped structure. FDS connecting parts are set on the upper surface of multiple support plates. An X-axis positioning mechanism is provided on the inner wall of the operating table, located between two adjacent sets of support plates. A Y-axis clamping mechanism is provided directly above the operating table and located on the outside of multiple support plates.

[0006] Preferably, a retaining sleeve is fixed on the upper surface of the square iron block, and an insert block is fixed on the lower surface of the support plate at a position corresponding to the retaining sleeve. The retaining sleeve and the insert block are inserted into each other. An insertion hole is provided on the side wall of the retaining sleeve, and a pin is inserted into the insertion hole. The insert block is fixed to the retaining sleeve by the pin. A limiting component for constraining the pin is provided inside the retaining sleeve.

[0007] Preferably, the limiting component includes: Two storage slots are symmetrically located on both sides of the inner wall of one of the sockets. A sliding groove is provided inside the sleeve and outside the storage slot. A locking block is slidably installed in the storage slot. A sliding plate is slidably installed in the sliding groove. A connecting rod is fixedly installed between the locking block and the sliding plate. A return spring is provided on the side of the sliding plate away from the locking block. A locking groove is provided on the outer circumference of the pin at the corresponding position of the two locking blocks. The two locking blocks engage with the locking groove.

[0008] Preferably, the card slot has rounded corners on its sides, the card block has a C-shaped cross-section, and guide surfaces are symmetrically arranged on both sides of the card block, with the rounded corners slidingly engaging with the guide surfaces.

[0009] Preferably, the X-axis positioning mechanism includes: A crossbar is fixedly installed on the inner wall of the operating table and located between two adjacent sets of support plates. A T-shaped block is fixed on the upper surface of the crossbar, a protrusion is fixed on the upper surface of the T-shaped block, and a positioning block is fixed at the middle of the upper surface of the protrusion.

[0010] Preferably, the Y-axis clamping mechanism includes: Two clamping plates are symmetrically arranged on the upper front and rear sides of the operating table. Side plates are symmetrically fixed on the upper surface of the operating table. The clamping plates are located on the inner side of the side plates. Electric push rods are symmetrically fixed on the outer wall of the side plates, and the telescopic rod end of the electric push rod passes through the side plate and is fixed to the inner clamping plate.

[0011] Preferably, the inner sidewall of the clamping plate is provided with a protective pad.

[0012] Preferably, the top height of the positioning block is 2-8 cm higher than the top surface of the support plate in the vertical direction.

[0013] The beneficial effects of this utility model are: 1. This T-shaped clamp block, through the use of a T-shaped support plate, effectively supports the FDS connecting parts on the Z-axis, solving the technical problems of incomplete support surface and unbalanced support force of traditional triangular seats, which lead to bending and deformation of parts during FDS high-pressure (above 3500N) operation, as well as the technical pain points of conventional angle iron blocking the position of screws; its T-shaped structure can provide Z-axis support to prevent parts from falling, and form a complete Y-axis support surface to offset lateral forces, while avoiding the screw layout area, ensuring no interference in FDS connection, and significantly improving the connection accuracy and pass rate of parts.

[0014] 2. This T-shaped clamp block, relying on the X-axis positioning structure of "positioning block with the top 2-8CM higher than the support plate + lateral protrusion of the support plate", solves the problem that traditional support components without dedicated X-axis positioning design are prone to parts moving or deviating along the X-axis; the two form a dual constraint of "pre-positioning + auxiliary limiting", which can accurately limit the X-axis displacement of the parts, completely avoid X-axis deviation, and further ensure the positional accuracy of the parts during the FDS connection process.

[0015] 3. This T-shaped clamping block, with its Y-axis clamping system of "electric push rod driving clamping plate + support plate Y-axis support", solves the problem of insufficient support force and easy bending deformation of parts when the traditional single support component is subjected to FDS high pressure lateral force. The two together form a dual guarantee of "active clamping + passive support", which can completely offset the high pressure lateral force, effectively prevent the bending deformation of parts, and greatly improve the connection stability and production quality of parts.

[0018] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0019] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0020] Example 1: This example provides a T-shaped clamp block, including: The operating table 1 has a square-shaped structure. Multiple sets of evenly distributed triangular support brackets 2 are symmetrically fixed on the inner wall of the operating table 1. Square iron blocks 3 are fixed to the upper surface of the triangular support brackets 2 by bolts. A support plate 5 is set directly above the square iron blocks 3. The support plate 5 has an earth-shaped structure. FDS connecting parts are set on the upper surface of multiple support plates 5. An X-axis positioning mechanism is provided on the inner wall of the operating table 1, located between two adjacent sets of support plates 5. A Y-axis clamping mechanism is provided directly above the operating table 1 and located on the outside of the multiple support plates 5.

[0021] Among them, the U-shaped structure of the operating table 1 provides a stable installation foundation for the whole device, the evenly distributed triangular brackets 2 ensure balanced support for the opposing iron blocks 3, and the core support plate 5 adopts a T-shaped structure. Compared with the problems of incomplete support surface and unbalanced support force of traditional triangular bracket standard parts, its T-shaped contour can fully fit with the lower surface of the FDS connecting parts, providing sufficient Z-direction support to prevent parts from falling off, and forming a complete Y-direction support surface through lateral protrusions, avoiding bending and deformation of parts under high pressure of 3500N or more in the FDS equipment; at the same time, the T-shaped structure of the support plate 5 avoids the FDS screw arrangement area, solving the defect of traditional conventional angle iron blocking the screw position, and ensuring that the screw installation is free of interference.

[0022] The X-axis positioning mechanism directly restricts the movement of the parts along the X-axis, preventing X-axis deviation. The Y-axis clamping mechanism applies clamping force from the outside, forming a bidirectional constraint with the Y-axis support of the support plate 5, further enhancing the Y-axis clamping stability. Compared with traditional support components, the overall positioning is more accurate, the support is more comprehensive, and the scrap rate of parts is significantly reduced.

[0023] Example 2: This example provides a T-shaped clamp block. In addition to the technical solutions of the above examples, it also has the following technical features: a sleeve 4 is fixed on the upper surface of the square iron block 3, and an insert block 6 is fixed on the lower surface of the support plate 5 at the position corresponding to the sleeve 4. The sleeve 4 and the insert block 6 are inserted and engaged. An insertion hole 7 is provided on the side wall of the sleeve 4. A pin 8 is inserted and installed in the insertion hole 7. The insert block 6 is fixed to the sleeve 4 by the pin 8. A limiting component for constraining the pin 8 is provided inside the sleeve 4.

[0024] The insertion and connection of the sleeve 4 and the plug 6 enables the rapid assembly of the support plate 5 and the square iron block 3. Compared with the traditional support components that rely on multiple sets of bolts and are time-consuming to disassemble and assemble, this structure does not require complicated tools. The support plate 5 can be installed simply by inserting the pin 8, which greatly shortens the process time. Moreover, the T-shaped structure of the support plate 5 can be accurately positioned directly above the square iron block 3 through this connection method, ensuring that its support position corresponds completely with the stress point of the FDS connecting parts, and avoiding the support misalignment caused by the installation deviation of the traditional support components.

[0025] After the pin 8 passes through the insertion hole 7, it forms a rigid fixation between the sleeve 4 and the insertion block 6. With the help of the limiting component inside the sleeve 4, it can prevent the support plate 5 from shifting due to the vibration of the FDS equipment. Traditional support components are prone to support shifting due to loose bolts, which can lead to X-axis deviation or Y-axis support failure.

[0026] Under this connection system, the T-shaped structure of support plate 5 can maintain its multi-directional support advantage and further amplify its dual benefits of "high efficiency + precision" compared to traditional support components through rapid and stable assembly.

[0027] Example 3: This example provides a T-shaped clamp block, which, in addition to the technical solutions of the above examples, also has the following technical features, including a limiting component: Two storage slots 9 are symmetrically opened on both sides of the inner wall of one of the sockets 7. A sliding groove 10 is opened inside the sleeve 4 and located outside the storage slot 9. A locking block 11 is slidably installed in the storage slot 9. A sliding plate 12 is slidably installed in the sliding groove 10. A connecting rod 13 is fixedly installed between the locking block 11 and the sliding plate 12. A return spring 14 is provided on the side of the sliding plate 12 away from the locking block 11. A slot 15 is opened on the outer circumference of the pin 8 at the corresponding position of the two locking blocks 11. The two locking blocks 11 are engaged with the slot 15.

[0028] The storage groove 9 provides a stable sliding trajectory for the locking block 11. The cooperation between the sliding groove 10 and the sliding plate 12 ensures the precise movement of the locking block 11. When the pin 8 is inserted into the socket 7, the locking block 11 is locked into the slot 15 under the elastic force of the return spring 14, realizing the automatic limit of the pin 8. This structure completely solves the problem of easy loosening of traditional support fasteners. If the traditional support is loose, it will cause the support to shift, which will cause the part to deviate on the X-axis or the clamping force on the Y-axis to decrease. However, this limiting component can ensure that the pin 8 always stably fixes the sleeve 4 and the locking block 6, so that the T-shaped structure of the support plate 5 can maintain a precise support posture.

[0029] The support plate 5 has a lateral protrusion on its T-shape to prevent X-axis deviation. In conjunction with this limiting component, it can prevent support failure caused by the installation misalignment of the support plate 5 itself. Compared with the traditional support component design that "relies only on the support structure without additional fixing guarantee", this structure has better support stability and can withstand FDS high-pressure operation for a long time, preventing parts from deforming.

[0030] Example 4: This example provides a T-shaped clamp block, which, in addition to the technical solutions of the above examples, also has the following technical features: the side of the slot 15 is provided with a rounded arc edge 16, the cross-section of the clamp block 11 is C-shaped, and the two sides of the clamp block 11 are symmetrically provided with guide surfaces 17, and the rounded arc edge 16 and the guide surface 17 are slidably engaged.

[0031] The rounded edge 16 reduces the friction between the locking block 11 and the pin 8 during insertion and removal. The inclined guide surface 17 ensures that the locking block 11 slides smoothly when the pin 8 is inserted. This design makes the disassembly and assembly of the support plate 5 more convenient. Compared with the problem of easy wear of parts during disassembly and assembly of traditional support components, which leads to a decrease in subsequent installation accuracy, this structure can extend the service life of the support plate 5 and the pin 8, and ensure that the support plate 5 maintains a precise installation position for a long time. The rounded edge 16 and the guide surface 17 make it easy for operators to insert the pin 8 and pull the pin 8 out of the socket 7 when applying force.

[0032] The T-shaped structure of the support plate 5 relies on precise installation to achieve the best support effect. If the installation is misaligned, the protrusion that prevents the X-axis from deviating will be misaligned with the parts, and the Y-axis support surface will also be unevenly stressed. The cooperation between the rounded corner 16 and the guide surface 17 ensures that the support plate 5 can be precisely aligned every time it is installed, so that the support advantage of the T-shaped structure is not compromised. Compared with the defect of traditional support components where "installation accuracy decreases with the number of uses", this structure can continuously guarantee the positioning and clamping effect.

[0033] Example 5: This example provides a T-shaped clamp block, which, in addition to the technical solutions of the above examples, also has the following technical features: the X-axis positioning mechanism includes: A crossbar 18 is fixedly installed on the inner wall of the operating table 1 and located between two adjacent sets of support plates 5. A T-shaped block 19 is fixed on the upper surface of the crossbar 18, a protrusion 20 is fixed on the upper surface of the T-shaped block 19, and a positioning block 21 is fixed at the middle of the upper surface of the protrusion 20.

[0034] Among them, the crossbar 18 and the T-block 19 provide a stable installation base for the positioning block 21. The height design of the positioning block 21 ensures that it contacts the part before the support plate 5 and directly performs X-axis pre-positioning of the part. Together with the side protrusion of the T-shaped structure of the support plate 5, the protrusion of the support plate 5 can form X-axis auxiliary constraint from the side of the part. The two form a dual X-axis anti-deviation system of "pre-positioning + auxiliary limit".

[0035] Traditional support components lack a dedicated X-axis positioning design and rely solely on friction on the support surface to prevent misalignment, which can easily lead to component movement under FDS high pressure. In this structure, the positioning block 21 first fixes the X-axis position, and the T-shaped protrusion of the support plate 5 further strengthens the constraint, completely solving the X-axis misalignment problem.

[0036] Meanwhile, the T-shaped structure of the support plate 5 avoids the installation area of ​​the positioning block 21, which does not affect the X-axis positioning and can give full play to the Y-axis support advantage. Compared with the problem of "positioning and support easily conflicting" of traditional support components, this design has better compatibility.

[0037] Example 6: This example provides a T-shaped clamping block, which, in addition to the technical solutions of the above examples, also has the following technical features: the Y-axis clamping mechanism includes: Two clamping plates 22 are symmetrically arranged on the upper front and rear sides of the operating table 1. Side plates 23 are symmetrically fixed on the upper surface of the operating table 1. The clamping plates 22 are located on the inner side of the side plates 23. Electric push rods 24 are symmetrically fixed on the outer wall of the side plates 23, and the telescopic rod end of the electric push rod 24 passes through the side plate 23 and is fixed to the inner clamping plate 22.

[0038] Among them, the side plate 23 provides a mounting carrier for the electric push rod 24. The electric push rod 24 drives the clamping plate 22 to apply a Y-axis clamping force to the part, forming a "active clamping + passive support" dual protection of the Y-axis with the Y-axis support surface of the support plate 5's T-shaped structure. Traditional support components rely on a single support surface to bear the Y-axis force, which can easily cause the part to bend due to insufficient support force. However, in this structure, the clamping plate 22 clamps from the outside and the support plate 5 supports from the inside, which can completely offset the high-pressure lateral force of the FDS equipment.

[0039] The Y-shaped support surface area of ​​the support plate 5 is much larger than that of traditional triangular seats or angle irons. Combined with the clamping force of the clamping plate 22, it can make the force on the parts evenly distributed and avoid deformation caused by local stress concentration. At the same time, the clamping plate 22 is located on the outside of the support plate 5, which does not cover the Y-shaped support area of ​​the support plate 5, nor does it interfere with the installation of FDS screws. Compared with the defects of traditional support components where "clamping structure covers the support or screw position", this design is more functional.

[0040] Example 7: This example provides a T-shaped clamp block, which, in addition to the technical solutions of the above examples, also has the following technical features: the inner sidewall of the clamping plate 22 is provided with a protective pad.

[0041] Among them, the protective pad on the inner wall of the clamping plate 22 not only prevents scratches on the surface of the parts, but also buffers the clamping force through elastic deformation. This design, together with the T-shaped structure of the support plate 5, forms a combination of "flexible protection + rigid support" - traditional support components either clamp too hard and damage the parts, or support too soft and easily deform. The T-shaped structure of the support plate 5 provides rigid Y-direction support to ensure that the parts do not bend, and the protective pad provides flexible clamping to ensure that the parts are not damaged.

[0042] In addition, the protective pad increases the friction with the parts, which can help prevent the parts from moving in the X direction. Together with the lateral protrusion of the support plate 5, it enhances the anti-deviation effect of the X axis. Compared with traditional support components that "only focus on the single function of support or clamping", this design takes into account both stability and protection, making the T-shaped support advantage of the support plate 5 more in line with actual production needs.

[0043] Example 8: This example provides a T-shaped clamp block, which, in addition to the technical solutions of the above examples, also has the following technical features: the top height of the positioning block 21 is 2-8 cm higher in the vertical direction than the height of the upper surface of the support plate 5 in the vertical direction.

[0044] The top of the positioning block 21 is 2-8 cm higher than the upper surface of the support plate 5. This size design ensures that the positioning block 21 contacts the X-axis reference surface of the part first, guiding the part to be accurately placed on the T-shaped support surface of the support plate 5, avoiding the misalignment of the support surface and the stress point of the support plate 5 due to the offset of the part placement. Traditional support components do not have this pre-positioning design, and the part is easy to be placed off-center, which in turn causes the X-axis to deviate or the Y-axis to be unevenly supported.

[0045] The T-shaped structure of the support plate 5 requires precise placement of parts to achieve the best effect: if the parts are skewed, the Z-axis support may be partially suspended, and the Y-axis support may be under force on one side. The height design of the positioning block 21 directly solves the problem of part placement accuracy, so that the T-shaped support surface of the support plate 5 can fully fit the parts. Compared with traditional support components that "rely on manual adjustment of part position, are inefficient and prone to errors", this design greatly improves assembly efficiency, while ensuring that the support advantages of the support plate 5 are fully utilized and reducing the failure rate of FDS connection.

[0046] Working principle: When using this T-shaped clamp block for FDS connection operations, the clamp is first pre-assembled: The square iron block 3 is fixed to the triangular support bracket 2 evenly distributed on the inner wall of the operating table 1 with bolts. Then, the insert block 6 of the support plate 5 is inserted into the sleeve 4 of the square iron block 3. The pin 8 is inserted through the insertion hole 7 to achieve the initial fixation of the support plate 5 and the square iron block 3. At this time, the locking block 11 of the limiting component inside the sleeve 4 is locked into the slot 15 of the pin 8 under the elastic force of the return spring 14, forming an axial constraint on the pin 8, ensuring that the support plate 5 is stably positioned directly above the square iron block 3, and the T-shaped structure of the support plate 5 is precisely aligned with the support requirement position of the FDS part to be connected.

[0047] Then, the FDS connecting parts are placed: the parts are placed on the upper surface of multiple support plates 5. Since the top height of the positioning block 21 is 2-8 cm higher than the upper surface of the support plate 5, the positioning block 21 contacts the parts before the support plate 5 and pre-positions them in the X direction. At the same time, the lateral protrusion of the T-shaped structure of the support plate 5 fits against the side of the parts, forming a double X-axis anti-deviation constraint of "pre-positioning + auxiliary limiting" to prevent the parts from moving along the X direction.

[0048] Next, the Y-axis clamping mechanism is activated: the electric push rod 24 on the side plate 23 drives the telescopic rod to extend, causing the inner clamping plate 22 to move towards the part until the inner wall of the clamping plate 22 or the protective pad is tightly attached to the outer periphery of the part, applying a Y-axis clamping force; at this time, the Y-axis support surface of the support plate 5 with its T-shape structure provides support from the inside of the part, forming a "active clamping + passive support" dual protection on the Y-axis with the clamping force on the outside of the clamping plate 22, which can offset the high pressure lateral force of more than 3500N generated during the operation of the FDS equipment and prevent the part from bending and deforming.

[0049] Next, the FDS connection operation is carried out: the FDS equipment connects the parts with screws. The T-shaped structure of the support plate 5 avoids the screw layout area and will not interfere with the screw installation. At the same time, the top support surface of the support plate 5 provides stable Z-axis support for the parts, preventing the parts from falling and ensuring the stability of the part position accuracy during the connection process.

[0050] After the operation is completed, the electric push rod 24 drives the clamp plate 22 to reset and release the parts, and pulls the pin 8 outward. The slot 15 of the pin 8 presses the guide surface 17 of the block 11, so that the block 11 compresses the reset spring 14 and disengages from the slot 15. After the pin 8 is pulled out, the connected parts can be removed, completing a single FDS connection operation cycle.

This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
