Description

Technical Field

[0001] This utility model belongs to the field of fixtures, specifically relating to a fixture tooling for fine-tuning the angle of a car's front armrest. Background Technology

[0002] In modern automobile manufacturing, every detail of the design and assembly is aimed at enhancing the user's driving experience and comfort. As an indispensable part of the vehicle interior, the front armrest not only provides additional support but also plays a crucial role in optimizing space utilization, enhancing passenger comfort, and creating a personalized interior atmosphere. Therefore, ensuring the accuracy of its installation angle is paramount, as it directly affects the comfort of the driver and passengers' arms, thus impacting the overall driving and riding experience.

[0003] To achieve multi-level frame adjustment, automotive front armrests often have various adjustment holes of different angles on the sheet metal frame to accommodate angle adjustments in different environments. However, when positioning and installing sheet metal parts and frames with different angle adjustment holes, the traditional method involves using multiple sets of fixtures to position and clamp the adjustment holes at different angles. This not only increases the manufacturing cost of the fixtures but also makes the fixture replacement operation relatively cumbersome, increasing the intensity of manual labor and affecting overall production efficiency. Furthermore, it is difficult to ensure the stability and accuracy of the positioning and clamping of the frame and sheet metal parts during frequent replacement operations, ultimately affecting the overall product quality of the automotive front armrest. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is: to propose a fixture for fine-tuning the angle of the front armrest of an automobile, which can realize the positioning and clamping of the adjustment holes of different angles on the sheet metal parts, has a simple overall structure, is convenient and quick to operate, and improves the versatility and flexibility of the fixture.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a fixture for fine-tuning the angle of a car front armrest. The car front armrest includes a frame and a sheet metal part. The sheet metal part extends outside the frame and has an adjustment hole formed at its end for adjusting the angle of the front armrest. The fixture includes a fixture table.

[0006] A positioning mechanism and a clamping mechanism are provided on the tooling table. The positioning mechanism is used to limit the relative placement position between the skeleton and the sheet metal part, so that when the sheet metal part moves to fit against the side wall of the skeleton, the clamping mechanism can fix the skeleton and the sheet metal part on the tooling table.

[0007] An adjustment mechanism and a stop mechanism are provided on the tooling table. A rotating seat is movably mounted on the adjustment mechanism. A locking block is connected to the movable end of the stop mechanism. The locking block passes through the rotating seat and is movably inserted into the adjustment hole to limit the displacement of the sheet metal part relative to the skeleton.

[0008] The locking block can rotate synchronously with the rotating seat when it rotates relative to the adjusting mechanism, so that the locking block is aligned with the adjusting hole and can be movably inserted into the adjusting hole to adapt to the positioning and clamping of the sheet metal part at different angles of the adjusting hole.

[0009] In the aforementioned fixture for fine-tuning the angle of a car front armrest, the adjustment mechanism further includes a positioning seat and a first adjustment member and a second adjustment member symmetrically arranged thereon. The positioning seat is disposed on the fixture table, and the rotating seat is rotatably disposed within the positioning seat. The two ends of the rotating seat are respectively movably abutted against the first adjustment member and the second adjustment member to drive the rotating seat to rotate relative to the positioning seat and adjust it to the required angle.

[0010] In the above-mentioned angle fine-tuning fixture for a car front armrest, both the first adjusting member and the second adjusting member include an adjusting rod and a locking nut. The adjusting rod passes through the positioning seat and movably abuts against the end of the rotating seat. When the rotating seat rotates to the required angle, the locking nut restricts the movement of the adjusting rod.

[0011] In the aforementioned angle fine-tuning fixture for a car front armrest, the positioning seat has a circular hole and a square hole. The square holes are symmetrically distributed on both sides of the circular hole in the radial direction and are interconnected. A rotating part is formed in the middle of the rotating seat. A first adjusting part and a second adjusting part are symmetrically connected on both sides of the rotating part. The rotating part is movably disposed in the circular hole, so that the first adjusting member can extend into the square hole and move against the first adjusting part, and the second adjusting member extends into the square hole and moves against the second adjusting part.

[0012] In the aforementioned angle fine-tuning fixture for a car front armrest, the stopping mechanism further includes:

[0013] A fixed base is provided on the tooling table, and a horizontally placed driving component is disposed on the fixed base;

[0014] A connecting block is connected to the output end of the drive unit. The connecting block is provided with a mounting groove and an anti-detachment component. An extension block is formed at the end of the locking block. The anti-detachment component can move through the extension block when the extension block is inserted into the mounting groove to prevent the extension block from detaching from the mounting groove.

[0015] In the aforementioned angle fine-tuning fixture for a car front armrest, the top and bottom walls of the extension block are not in contact with the mounting groove, and a waist-shaped clearance hole is provided in the extension block, through which the anti-detachment component passes.

[0016] In the aforementioned angle fine-tuning fixture for a car front armrest, an anti-misalignment block is also connected in the mounting groove. A guide hole is provided in the first adjustment part, and the anti-misalignment block moves through the guide hole so that the sheet metal part can overlap the end of the anti-misalignment block.

[0017] In the aforementioned angle fine-tuning fixture for a car front armrest, the positioning seat is provided with a locking groove and a locking block. The length direction of the locking groove is tangent to the circular hole and is connected to it. The top end of the rotating part is provided with a groove, and the locking block is disposed in the locking groove and extends movably into the groove to restrict the displacement of the rotating part along the axial direction of the circular hole.

[0018] In the aforementioned angle fine-tuning fixture for a car front armrest, the positioning mechanism includes:

[0019] A support base is provided on the tooling table;

[0020] Positioning posts and positioning blocks are distributed on the support base. The frame is provided with positioning holes and conical holes. The positioning posts are movably inserted into the positioning holes, and the positioning blocks are movably abutted against the inner wall of the conical holes to restrict the frame on the support base.

[0021] Limiting seats are distributed at both ends of the support seat, and a positioning groove is formed between the limiting seats and the support seat to allow the sheet metal part to be placed and movably attached to the side wall of the frame.

[0022] A contour block and a limiting block are disposed on the side wall of the positioning seat. A contour groove is formed on the contour block so that the end of the sheet metal part can move and abut against the contour groove. An arc-shaped extension is formed at the top of the limiting block. One side of the sheet metal part moves and fits tightly against the positioning seat, and the other side moves and fits tightly against the arc-shaped extension.

[0023] In the aforementioned angle fine-tuning fixture for a car front armrest, the clamping mechanism includes:

[0024] A first clamping cylinder is mounted on the tooling table, and a clamping block is connected to the output end of the first clamping cylinder.

[0025] A connecting seat is provided on the tooling table. The end of the clamping block near the first clamping cylinder is hinged to a connecting plate. The end of the connecting plate away from the clamping block is movably hinged to the connecting seat, so that when the first clamping cylinder is driven, it can drive the clamping block to move closer to or away from the skeleton.

[0026] The second clamping cylinder is movably disposed at the bottom of the tooling table, and the output end of the second clamping cylinder is connected to a clamping block;

[0027] A connecting rod is provided on the top wall of the tooling table. An extension plate is symmetrically provided at the end of the connecting rod. A through slot is provided on the tooling table. The clamping block passes through the through slot and is movably hinged to the extension plate, so that when the second clamping cylinder is driven, it can drive the clamping block to rotate relative to the extension plate, so that the top of the clamping block can movably clamp the sheet metal part against the positioning seat.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) The present invention provides a micro-adjustment fixture for the angle of the front armrest of an automobile. By adjusting the horizontal height of the two adjustment parts through the first adjustment part and the second adjustment part, the rotating seat can drive the locking block to rotate synchronously during the rotation process. This ensures that the locking block can be accurately aligned with the adjustment hole and inserted into it regardless of the angle of the adjustment hole on the sheet metal part, thereby achieving effective fixation at different angle positions. The overall operation is simple and quick, and it can adapt to the needs of various angle adjustments. It effectively improves the versatility and flexibility of the fixture, and also provides a guarantee for production efficiency and final product quality.

[0030] (2) The non-contact design of the top and bottom walls of the extension block with the mounting groove ensures that there is enough space for the locking block to be finely adjusted relative to the positioning seat. At the same time, the anti-slip part with the through waist-shaped clearance hole can prevent the extension block from falling out of the mounting groove and ensure the stability of the locking block when rotating with the rotating part. This effectively prevents the extension block and the connecting block from getting stuck, which would affect the smoothness of the locking block angle adjustment.

[0031] (3) The locking block can be inserted into the locking groove and the recess at the same time, thereby effectively restricting the displacement of the rotating part along the axis of the circular hole, and preventing the rotating part from extending out of the positioning seat and affecting the stability of the locking block when positioning and clamping the sheet metal part.

[0044] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0045] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0046] like Figures 1 to 6 As shown, this utility model discloses a fixture for fine-tuning the angle of a car front armrest. The car front armrest includes a frame 10 and a sheet metal part 11. The sheet metal part 11 extends beyond the frame 10 and has an adjustment hole 110 at its end for adjusting the angle of the front armrest. The fixture includes a fixture table 2; a positioning mechanism 3; and a clamping mechanism 4, which are mounted on the fixture table 2. The positioning mechanism 3 limits the relative placement of the frame 10 and the sheet metal part 11, so that when the sheet metal part 11 moves to fit against the side wall of the frame 10, the clamping mechanism 4 fixes the frame 10 and the sheet metal part 11 on the fixture table 2. The adjusting mechanism 5 and the stopping mechanism 6 are set on the tooling table 2. The adjusting mechanism 5 is movably mounted with a rotating seat 50. The moving end of the stopping mechanism 6 is connected to a locking block 60. The locking block 60 passes through the rotating seat 50 and is movably inserted into the adjusting hole 110 to limit the displacement of the sheet metal part 11 relative to the frame 10. The locking block 60 can rotate synchronously when the rotating seat 50 rotates relative to the adjusting mechanism 5, so that the locking block 60 is aligned with the adjusting hole 110 and can be movably inserted into the adjusting hole 110 to adapt to the positioning and clamping of the sheet metal part 11 at different angles of the adjusting hole 110.

[0047] This embodiment primarily aims to achieve the positioning and clamping of the frame 10 and sheet metal part 11 on the front armrest of a car. Before starting, a worker or robot can place the sheet metal part 11 and the frame 10 on the positioning mechanism 3 of the tooling table 2. Through the initial positioning between the two, it is effectively ensured that the sheet metal part 11 is tightly attached to the side wall of the frame 10, thereby ensuring the subsequent assembly quality. As the clamping mechanism 4 restricts the relative position between the two, it ensures that no displacement will occur during subsequent operations. It is worth noting that the sheet metal parts 11 on different front armrests of cars have different angle adjustment holes 110. These adjustment holes 110 can realize the adjustment of the position of the frame 10. In order to accommodate the positioning and clamping of sheet metal parts 11 with different adjustment holes 110, this embodiment can adjust the angle of the locking block 60 by rotating the seat 50 before the locking block 60 is positioned and clamped to the adjustment hole 110. Specifically, as shown in the figure... Figures 1 to 3As shown, the worker can control the adjusting mechanism 5 to rotate the rotating seat 50 according to the required angle of the adjusting hole 110. Since the locking block 60 is inserted into the rotating seat 50 (but not into the adjusting hole 110), the locking block 60 can rotate synchronously, thus aligning the locking block 60 with the adjusting hole 110 formed at the end of the sheet metal part 11. Once the required angle is reached, the moving end of the stop mechanism 6 can continue to push the locking block 60, inserting it into the adjusting hole 110 of the sheet metal part 11, effectively preventing unnecessary displacement of the sheet metal part 11 relative to the frame 10. Therefore, this fixture can indirectly adjust the angle of the locking block 60 through the rotating seat 50, allowing it to adapt to different angles of the adjusting hole 110. The overall operation is simple and quick, and multiple angle adjustment needs can be met on one fixture, effectively improving the versatility and flexibility of the fixture, while also ensuring production efficiency and final product quality.

[0048] The adjustment mechanism 5 also includes a positioning seat 51 and a first adjustment member 52 and a second adjustment member 53 symmetrically arranged thereon. The positioning seat 51 is set on the tooling table 2, and the rotating seat 50 is rotatably set inside the positioning seat 51. The two ends of the rotating seat 50 are respectively movably abutted against the first adjustment member 52 and the second adjustment member 53, so as to drive the rotating seat 50 to rotate relative to the positioning seat 51 and adjust it to the required angle.

[0049] like Figures 1 to 3 As shown, with the locking block 60 inserted into the rotating seat 50, the operator can adjust the first adjusting member 52 and the second adjusting member 53 separately or simultaneously. Since the first adjusting member 52 and the second adjusting member 53 are symmetrically arranged, they will apply equal but opposite forces to the rotating seat 50. This allows the rotating seat 50 to rotate smoothly within the positioning seat 51, thereby driving the locking block 60 to rotate synchronously to the required angle. This ensures that when the moving end of the stop mechanism 6 pushes the locking block 60 to move towards the sheet metal part 11, it can be accurately inserted into the adjusting hole 110, thus fixing the relative position between the sheet metal part 11 and the frame 10, and providing assurance for the subsequent assembly quality.

[0050] Both the first adjusting member 52 and the second adjusting member 53 include an adjusting rod 540 and a locking nut 541. The adjusting rod 540 passes through the positioning seat 51 and moves against the end of the rotating seat 50. When the rotating seat 50 rotates to the required angle, the locking nut 541 restricts the movement of the adjusting rod 540.

[0051] Preferably, such as Figure 2As shown, for the rotation adjustment of the rotating seat 50, the first adjusting member 52 and the second adjusting member 53 in this embodiment both use adjusting rods 540 and locking nuts 541. Specifically, when it is necessary to adjust the angle of the locking block 60 (at this time, the locking block 60 is inserted into the rotating seat 50), the operator can adjust any adjusting rod 540 on the rotating seat 50. That is, by moving the adjusting rod 540 in the vertical direction, for example, when any adjusting rod 540 moves downward to apply rotational force to the rotating seat 50, the other adjusting rod 540 can move upward in the vertical direction to provide space for the rotating seat 50 to rotate. At the same time, when the two adjusting rods 540 are pressed against both ends of the rotating seat 50, the stability of the rotating seat 50 after adjustment is effectively ensured. This also serves as a guide and limiter when the locking block 60 is subsequently inserted into the adjusting hole 110. It should be noted that the adjusting rod 540 in this embodiment can be realized by using a hexagonal screw and a locking nut 541 through threaded engagement. When the adjusting rod 540 adjusts the rotating seat 50 to the required angle, the locking nut 541 can be used to ensure the stability of the adjusting rod 540.

[0052] The positioning seat 51 has a circular hole 510 and a square hole 511. The square holes 511 are symmetrically distributed on both sides of the circular hole 510 in the radial direction and are interconnected. A rotating part 500 is formed in the middle of the rotating seat 50. A first adjusting part 501 and a second adjusting part 502 are symmetrically connected on both sides of the rotating part 500. The rotating part 500 is movably disposed in the circular hole 510, so that the first adjusting member 52 can extend into the square hole 511 and move against the first adjusting part 501. The second adjusting member 53 extends into the square hole 511 and moves against the second adjusting member 53.

[0053] like Figures 1 to 3As shown, during the angle adjustment of the locking block 60, the locking block 60 can be pre-push into the rotating seat 50 by the movable end of the stop mechanism 6. At this time, the operator can adjust the angle of the adjustment hole 110 by pressing the first adjustment part 501 or the second adjustment part 502 downwards through the adjustment rod 540 on one side. Relying on the rotation of the rotating part 500 in the circular hole 510, the second adjustment part 502 or the first adjustment part 501 rotates synchronously with the rotating part 500 as the adjustment rod 540 on the other side is raised, thereby adjusting the locking block 60 inserted inside to the required angle. It can be seen that the cooperation between the circular hole 510 and the rotating part 500 provides central positioning, allowing the rotating seat 50 to rotate around a fixed axis, improving the accuracy of angle adjustment. The design of the square hole 511 facilitates the installation and disassembly of the overall structure of the rotating seat 50, and effectively restricts the movement path of the first adjustment part 501 and the second adjustment part 502 while ensuring that the adjustment part has sufficient space for angle adjustment, ensuring stability and reliability during the adjustment process. It should be noted that in this embodiment, the vertical opening height of the square hole 511 is greater than the vertical thickness of the first adjustment part 501 and the second adjustment part 502, which effectively prevents positional interference when the first adjustment part 501 and the second adjustment part 502 rotate with the rotating part 500, thereby improving the smoothness of the rotating seat 50 driving the locking block 60 to adjust the angle.

[0054] The stopping mechanism 6 also includes: a fixed base 61, which is set on the tooling table 2, and a horizontally placed driving member 62 is arranged on the fixed base 61; a connecting block 63, which is connected to the output end of the driving member 62, and a mounting groove 630 and an anti-detachment member 631 are provided in the connecting block 63; an extension block 600 is formed at the end of the locking block 60; the anti-detachment member 631 can move through the extension block 600 when the extension block 600 is inserted into the mounting groove 630, so as to prevent the extension block 600 from detaching from the mounting groove 630.

[0055] like Figures 1 to 3As shown, after the adjustment rod 540 completes the angle adjustment of the first adjustment part 501 and the second adjustment part 502, the output end of the drive member 62 can insert the locking block 60 into the adjustment hole 110 at the adjusted angle through the connecting block 63 to fix the position of the sheet metal part 11 relative to the frame 10. In this process, in order to make the locking block 60 fit the adjustment hole 110 on the sheet metal part 11, it is necessary to ensure that the shape of the locking block 60 and the shape of the adjustment hole 110 are consistent (in this embodiment, a quincunx design is adopted, that is, the hole through which the locking block 60 passes in the rotating part 500, the locking block 60, and the adjustment hole 110 are all quincunx-shaped). The mounting groove 630 on the connecting block 63 serves as a guide for the installation of the extension block 600. At the same time, the anti-detachment member 631 passes through the extension block 600 and the mounting groove 630, effectively preventing the locking block 60 from accidentally detaching during operation and ensuring the reliability of the connection between the extension block 600 and the connecting block 63. Furthermore, this embodiment achieves an automated locking process through the drive component 62, reducing manual operation and lowering the operational difficulty. Preferably, the anti-loosening component 631 in this embodiment mainly consists of an anti-loosening nut 231 and an internal hexagon screw. After the internal hexagon screw passes through the mounting groove 630 and the extension block 600, it can be tightened to the bottom wall of the connecting block 63 by the anti-loosening nut 231 on the internal hexagon screw, ensuring the stability of the extension block 600 and the connecting block 63 during assembly.

[0056] More preferably, such as Figure 2 and Figure 3 As shown, in this embodiment, the top and bottom walls of the extension block 600 are not in contact with the mounting groove 630. This design significantly reduces the friction between the two, allowing the locking block 60 to move in and out of the mounting groove 630 more smoothly, thus improving operational efficiency. It is worth noting that a waist-shaped clearance hole 600a is provided in the extension block 600. The length direction of the waist-shaped clearance hole 600a is exactly perpendicular to the moving direction of the locking block 60. By using the anti-disengagement component 631 passing through the waist-shaped clearance hole 600a, the displacement of the extension block 600 relative to the anti-disengagement component 631 along the moving direction of the locking block 60 can be effectively restricted. It is also because of the existence of the waist-shaped clearance hole 600a that a certain tolerance range is allowed, so that even if there are slight manufacturing or assembly errors, the anti-disengagement component 631 can still pass smoothly through the extension block 600, improving the accuracy of locking. On the other hand, during the rotation of the locking block 60 by the rotating part 500, a certain space is provided for the extension block 600 to rotate synchronously with the locking block 60 in the mounting groove 630, which effectively avoids the smoothness and stability of the locking block 60 when adjusting the angle with the rotating part 500 due to positional interference between the extension block 600 and the connecting block 63.

[0057] The positioning seat 51 is provided with a locking groove 512 and a locking block 513. The length direction of the locking groove 512 is tangent to the circular hole 510 and is connected to it. The top end of the rotating part 500 is provided with a groove 500a. The locking block 513 is disposed in the locking groove 512 and extends movably into the groove 500a to limit the displacement of the rotating part 500 along the axial direction of the circular hole 510.

[0058] More preferably, to ensure that the rotating seat 50 only drives the locking block 60 to rotate in the radial direction of the circular hole 510, this embodiment effectively restricts the displacement of the rotating part 500 along the axial direction of the circular hole 510 by inserting the locking block 513 into the locking groove 512 and the recess 500a. The locking block 513 also provides additional constraint, preventing axial displacement of the rotating seat 50 due to external forces during operation, thus enhancing the stability of the structure. It should be noted that when the locking block 513 extends into the recess 500a, it only contacts the two side walls of the recess 500a, not the bottom wall. This ensures that the rotating part 500 has sufficient rotational space to drive the first adjusting part 501 and the second adjusting part 502 to rotate, making the angle adjustment of the locking block 60 smoother. It also facilitates the subsequent disassembly or maintenance of the locking block 513 and the rotating seat 50, extending the service life of the fixture.

[0059] More preferably, such as Figure 2 and Figure 3 As shown, this embodiment also includes an anti-misalignment block 64 connected within the mounting slot 630. A guide hole 501a is provided in the first adjustment part 501. When the driving member 62 drives the connecting block 63 to move, the anti-misalignment block 64 can move through the guide hole 501a, providing additional guidance and ensuring that locking can only be performed when the sheet metal part 11 is in the correct position. This avoids assembly errors caused by incorrect positioning and enhances the stability of the structure. It should be noted that in this embodiment, the installation and removal of the anti-misalignment block 64 and the connecting block 63 can also be achieved using an anti-detachment member 631, whose structure and working principle are the same as described above, and will not be elaborated further here.

[0060] More preferably, such as Figure 2 and Figure 3As shown, in this embodiment, adjustment seats 23 located on both sides of the positioning seat 51 can also be set on the tooling table 2. Each adjustment seat 23 is equipped with an adjustment screw 230 and a nut 231. The adjustment screw 230 is pressed against the side wall of the positioning seat 51, and the positioning seat 51 is restricted to the adjusted position after the nut 231 on the adjustment screw 230 is tightened. This realizes the fine adjustment of the positioning seat 51 on the tooling table 2, so as to compensate for the errors generated during the manufacturing and processing of the rotating seat 50 or the positioning seat 51, and ensure that the locking block 60 can be accurately and quickly inserted into the adjustment hole 110 after adjusting the required angle, so as to complete the positioning and clamping of the sheet metal part 11.

[0061] The positioning mechanism 3 includes: a support base 30, mounted on the tooling table 2; positioning pins 31 and positioning blocks 32, distributed on the support base 30; a positioning hole 100 and a conical hole 101 are provided on the frame 10, the positioning pin 31 is movably inserted into the positioning hole 100, and the positioning block 32 movably abuts against the inner wall of the conical hole 101 to restrict the frame 10 on the support base 30; and limiting seats 33, distributed at both ends of the support base 30, with the limiting seats 33 and the support base 30 sharing a common... The positioning seat 51 has a positioning groove 340 for placing the sheet metal part 11 and allowing it to move and fit tightly against the side wall of the frame 10; the contour block 35 and the limiting block 36 are set on the side wall of the positioning seat 51, the contour block 35 has a contour groove 350 for allowing the end of the sheet metal part 11 to move and abut against the contour groove 350; the top of the limiting block 36 has an arc-shaped extension 360, one side of the sheet metal part 11 moves and fits tightly against the positioning seat 51, and the other side moves and fits tightly against the arc-shaped extension 360.

[0062] like Figures 1 to 4As shown, during the installation of the frame 10, this embodiment has a support block 22 on the tooling table 2 that can be reciprocated vertically by a cylinder or hydraulic cylinder. The support block 22 is located between two support seats 30. It can provide stable support for the frame 10 as a whole, and also ensure that the frame 10 can slowly fall onto the support seats 30, thus buffering and protecting the mass of the frame 10. As the frame 10 gradually falls towards the support seats 30, the positioning pin 31 is inserted into the positioning hole 100, and the positioning block 32 is also pressed against the inner wall of the tapered hole 101. With the cooperation of the two, the precise positioning of the frame 10 and the sheet metal part 11 is ensured, the assembly error is reduced, and the product quality is improved. Regarding the installation and placement of the sheet metal part 11, the positioning groove 340 formed by the support base 30 and the limiting base 33 ensures that one end of the sheet metal part 11 can fall into the positioning groove 340 and stick to the side wall of the frame 10. At this time, the other end of the sheet metal part 11 also falls into the contour block 35. The contour groove 350 can play a preliminary positioning effect on the end of the sheet metal part 11. As the end of the sheet metal part 11 falls into the contour groove 350, the end of the sheet metal part 11 will inevitably gradually move and engage between the arc extension 360 formed by the positioning base 51 and the limiting block 36. The arc extension 360, in conjunction with the positioning base 51, further restricts the left and right displacement of the sheet metal part 11 in the contour groove 350, thereby ensuring that the overall structure of the sheet metal part 11 and the frame 10 are in the accurate assembly position. As can be seen, this embodiment, through a reasonable layout design, makes the installation of sheet metal parts 11 and frame 10 easier, reduces the difficulty of operation, improves work efficiency, and avoids the differences that occur during manual positioning and installation.

[0063] The clamping mechanism 4 includes: a first clamping cylinder 40, mounted on the tooling table 2, with a clamping block 400 connected to the output end of the first clamping cylinder 40; a connecting seat 21, mounted on the tooling table 2, with a connecting plate 401 hinged to the end of the clamping block 400 near the first clamping cylinder 40, and the end of the connecting plate 401 away from the clamping block 400 movably hinged to the connecting seat 21, so that when the first clamping cylinder 40 is driven, it can drive the clamping block 400 to move closer to or away from the frame 10; and a second clamping cylinder 41, movably mounted on the tooling table 2. At the bottom of the tooling table 2, the output end of the second pressing cylinder 41 is connected to a pressing block 410; the connecting rod 42 is set on the top wall of the tooling table 2, and the end of the connecting rod 42 is symmetrically provided with an extension plate 420. A through groove 20 is opened on the tooling table 2, and the pressing block 410 passes through the through groove 20 and is movably hinged to the extension plate 420, so that when the second pressing cylinder 41 is driven, it can drive the pressing block 410 to rotate relative to the extension plate 420, so that the top of the pressing block 410 can movably press the sheet metal part 11 against the positioning seat 51.

[0064] like Figure 1 , Figure 5 and Figure 6As shown, this embodiment also employs two methods to clamp the frame 10 and the sheet metal part 11. Specifically, after the positioning pin 31 and positioning block 32 have accurately positioned the frame 10, the output end of the first clamping cylinder 40 can push the clamping block 400 upward. Since the connecting plate 401 is hinged between the connecting seat 21 and the clamping block 400, the clamping block 400 will rotate along the hinge point, gradually approaching and finally clamping onto the frame 10, firmly fixing the frame 10 onto the support seat 30. Similarly, when the second clamping cylinder 41 is activated, its output end pushes the bottom end of the pressing block 410 along... Figure 5 Moving to the left, since the clamping block 410 passes through the through slot 20 on the tooling table 2 and is movably hinged to the extension plate 420 at the end of the connecting rod 42, the clamping block 410 will rotate at its hinge point with the extension plate 420, thereby causing the top of the clamping block 410 to move along... Figure 5 It gradually moves to the right and finally presses against the sheet metal part 11, firmly fixing it to the positioning seat 51. It can be seen that the pressing structure of the first pressing cylinder 40 is relatively simple, reducing manual operation; while the second pressing cylinder 41 uses the lever principle to enable the pressing block 410 to accurately and stably restrict the movement of the sheet metal part 11 relative to the frame 10, providing a guarantee for the subsequent product quality.
