Description

Technical Field

[0001] This utility model relates to the field of vehicle platform processing technology, specifically a limiting tooling for vehicle platform processing. Background Technology

[0002] Vehicle-mounted platform drilling equipment is a specialized piece of equipment used for drilling operations on vehicle-mounted platforms, such as automobiles, trucks, and engineering vehicles, or on their on-board processing platforms or parts. Its design must be adapted to the vibration, space constraints, and processing accuracy requirements of the vehicle-mounted environment.

[0003] Existing patent CN213163229U provides a positioning fixture for drilling automotive parts. It involves placing the part to be drilled on the upper end of a first and second measuring pad, within the area between a sliding plate and a second fixed plate. After the workpiece is placed stably, the turntable and rotating rod are manually rotated, causing a first threaded rod to move spirally within the threaded through-hole of the first fixed plate, pushing the sliding plate towards the second fixed plate, thereby clamping the part within the sliding plate and the second fixed plate. However, this method requires repeated manual tightening to ensure clamping, resulting in a long fixing time for a single workpiece. Furthermore, the clamping force is entirely controlled by feel; too loose and it easily slips, too tight and it may deform the workpiece, especially affecting easily deformable materials such as aluminum alloys. It also lacks the ability to quantitatively determine whether the workpiece is completely fixed, often resulting in a loose clamp, where the surface is clamped but there are actually tiny gaps, causing slight movement of the workpiece during drilling and producing defective holes. Therefore, a limiting fixture for machining on an automotive platform is proposed. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a limiting fixture for processing vehicle-mounted platforms, solving the problem of inconvenient positioning during processing of vehicle-mounted platforms.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a limiting fixture for processing on a vehicle platform, comprising a processing platform, wherein four sliding grooves are provided on the upper surface of the processing platform; The processing platform is equipped with a limiting mechanism, which includes a moving gantry, drilling equipment, motor, worm gear, worm wheel, transmission roller, disc, first support rod, second support rod, T-shaped moving block, sliding roller, fixed plate, clamping plate, and spring.

[0006] Preferably, the movable gantry frame is disposed on the outer surface of the processing platform, and the drilling equipment is slidably sleeved on the outer surface of the movable gantry frame.

[0007] Preferably, the motor is fixedly installed in the inner wall of the processing platform, and the worm gear is fixedly installed at the output end of the motor.

[0008] Preferably, the worm gear is meshed with the outer surface of the worm, and the transmission roller is fixedly sleeved on the inner surface of the worm gear.

[0009] Preferably, the disc is fixedly mounted on the upper end of the transmission roller, and four first support rods are fixedly mounted on the outer surface of the disc.

[0010] Preferably, the four second rods are rotatably connected to the ends of the four first rods away from the disk.

[0011] Preferably, the four T-shaped moving blocks are rotatably connected to the upper ends of the four second support rods, and the vertical plates of the four T-shaped moving blocks are slidably sleeved in the inner walls of the four sliding grooves.

[0012] Preferably, the four sliding rollers are respectively slidably sleeved in the inner wall of the four T-shaped moving block cross plate, and the four fixed plates are respectively fixedly installed on the opposite ends of the four sliding rollers.

[0013] Preferably, the four clamps are fixedly installed at opposite ends of the four sliding rollers.

[0014] Preferably, the four springs are respectively fixedly installed on the opposite sides of the four clamping plates, and the opposite ends of the four springs are respectively fixedly installed on the opposite sides of the four T-shaped moving block cross plates.

[0015] (III) Beneficial Effects Compared with the prior art, this utility model provides a limiting fixture for processing on a vehicle platform, which has the following beneficial effects: 1. The limiting fixture processed by this vehicle-mounted platform is driven by a motor through a worm gear and worm wheel transmission, which drives the disc to rotate via the transmission roller. This causes the four first support rods to move in a circular motion synchronously. Then, the second support rods link the T-shaped moving blocks to slide along the slide groove, ultimately causing the four sets of clamping plates to move closer to or further away from the machining center at the same time. This ensures that the clamping force is applied evenly from all sides. Combined with the elastic force generated by the compression spring of the sliding roller, it can adapt to workpieces of different sizes and avoid workpiece deformation caused by rigid clamping, thus significantly improving the limiting stability.

[0016] 2. The limiting fixture processed by this vehicle-mounted platform can control the reciprocating sliding of the T-shaped moving block through the transmission relationship of components such as worm gear, worm, transmission roller, and disc by rotating the motor in both forward and reverse directions. This achieves automatic clamping and releasing of the clamping plate without manual intervention. The elastic restoring characteristics of the spring ensure the continuity of the action. Combined with the drilling equipment on the mobile gantry, the position can be flexibly adjusted, which greatly shortens the single processing cycle time and improves the batch processing efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a new technical solution: a limiting tooling for processing on a vehicle platform, including a processing platform 1, and four sliding grooves 16 are provided on the upper surface of the processing platform 1; The processing platform 1 is equipped with a limiting mechanism, which includes a movable gantry frame 2, a drilling device 3, a motor 4, a worm gear 5, a worm wheel 6, a transmission roller 7, a disc 8, a first support rod 9, a second support rod 10, a T-shaped moving block 11, a sliding roller 12, a fixed plate 13, a clamping plate 14, and a spring 15.

[0021] Furthermore, the movable gantry 2 is set on the outer surface of the processing platform 1, and the drilling equipment 3 is slidably sleeved on the outer surface of the movable gantry 2.

[0022] Furthermore, the motor 4 is fixedly installed in the inner wall of the processing platform 1, and the worm gear 5 is fixedly installed at the output end of the motor 4.

[0023] Furthermore, the worm gear 6 is meshed with the outer surface of the worm 5, and the transmission roller 7 is fixedly sleeved on the inner surface of the worm gear 6.

[0024] Furthermore, the disc 8 is fixedly mounted on the upper end of the transmission roller 7, and four first support rods 9 are fixedly mounted on the outer surface of the disc 8.

[0025] Furthermore, the four second support rods 10 are rotatably connected to the ends of the four first support rods 9 that are away from the disk 8.

[0026] Furthermore, the four T-shaped movable blocks 11 are rotatably connected to the upper ends of the four second support rods 10, and the vertical plates of the four T-shaped movable blocks 11 are slidably sleeved in the inner walls of the four sliding grooves 16.

[0027] Furthermore, the four sliding rollers 12 are respectively slidably sleeved in the inner wall of the four T-shaped moving blocks 11, and the four fixed plates 13 are respectively fixedly installed at the opposite ends of the four sliding rollers 12.

[0028] Furthermore, the four clamping plates 14 are respectively fixedly installed at the opposite ends of the four sliding rollers 12.

[0029] Furthermore, four springs 15 are respectively fixedly installed on the opposite sides of the four clamping plates 14, and the opposite ends of the four springs 15 are respectively fixedly installed on the opposite sides of the cross plates of the four T-shaped moving blocks 11. When the motor 4 is started, the output end of the motor 4 drives the worm 5 to rotate. Since the worm wheel 6 is meshed with the outer surface of the worm 5, the rotation of the worm 5 will drive the worm wheel 6 to rotate. The transmission roller 7 is fixedly sleeved on the inner surface of the worm wheel 6, so the transmission roller 7 rotates together with the worm wheel 6. The disc 8 is fixedly installed on the upper end of the transmission roller 7. The rotation of the transmission roller 7 drives the disc 8 to rotate synchronously. The four first support rods 9 are fixed on the outer surface of the disc 8 and make circumferential motion with the rotation of the disc 8. At this time, the second support rod 10, which is rotatably connected to the first support rod 9, is driven, thereby pulling or pushing the T-shaped moving block 11 rotatably connected to it. Since the vertical plate of the T-shaped moving block 11 is slidably sleeved in the inner wall of the slide groove 16, the T-shaped moving block 11 slides along the slide groove 16 towards or away from the machining center under the action of the second support rod 10. When the T-shaped moving block 11 moves, the sliding roller 12 on its horizontal plate moves accordingly, driving the fixed plate 13 and the clamping plate 14 to move synchronously. When clamping the workpiece, as the T-shaped moving block 11 approaches the machining center, the clamping plate 14 first contacts the workpiece. As it continues to move, the sliding roller 12 slides on the inner wall of the horizontal plate of the T-shaped moving block 11, and the spring 15 is compressed, generating elastic force, which makes the clamping plate 14 tightly press against the workpiece, achieving stable positioning. During the machining process, the drilling device 3 can slide on the outer surface of the moving gantry 2 to adjust its position and perform drilling operations on the workpiece after it is positioned. After machining is completed, the motor 4 reverses, and through the above transmission relationship, it drives each component to move in the opposite direction. The T-shaped moving block 11 moves away from the machining center, the spring 15 returns to its original state, and the clamping plate 14 releases the workpiece, completing one machining cycle. The limiting fixture processed by this vehicle-mounted platform uses a motor-driven worm gear and worm wheel transmission to drive the disk to rotate via the transmission roller. This causes the four first support rods 9 to move in a circular motion synchronously. Then, the second support rod 10 links the T-shaped moving block 11 to slide along the slide groove 16, ultimately causing the four sets of clamping plates 14 to move closer to or further away from the machining center at the same time. This ensures that the clamping force is applied evenly from all sides. Combined with the elastic force generated by the compression spring 15 of the sliding roller 12, it can adapt to workpieces of different sizes and avoid workpiece deformation caused by rigid clamping, significantly improving the limiting stability. The limiting fixture processed by this vehicle-mounted platform can control the reciprocating sliding of the T-shaped moving block 11 through the transmission relationship of components such as the worm wheel 5, worm 6, transmission roller 7, and disk 8 by the forward and reverse rotation of the motor 4, realizing the automatic clamping and releasing of the clamping plate 14. The whole process does not require manual intervention, and the elastic restoring characteristic of the spring 15 ensures the continuity of the action. Combined with the drilling equipment 3 on the mobile gantry 2, the position can be flexibly adjusted, greatly shortening the single processing cycle time and improving the batch processing efficiency.

[0030] Structural Description: Machining Platform 1: Machining Platform 1 is the basic support component of the entire limiting fixture, providing an installation and operating carrier for all other components. The four sliding grooves 16 on its surface provide a guide path for the sliding of the T-shaped moving block 11, ensuring the displacement stability of the limiting mechanism. At the same time, it carries the on-board platform workpiece to be processed and serves as the reference working surface for machining operations. Mobile gantry 2: The mobile gantry 2 is set on the outer surface of the processing platform 1 and serves as the installation support structure for the drilling equipment 3. It provides a sliding track for the drilling equipment 3, allowing the drilling equipment 3 to slide and adjust its position along its outer surface, thereby realizing the drilling of workpieces at different positions on the processing platform 1, expanding the processing range and flexibility. Drilling equipment 3: Drilling equipment 3 is slidably sleeved on the outer surface of the movable gantry 2. It is the component that directly performs the processing operation. With the support and guidance of the movable gantry 2, it can be adjusted to a suitable position to perform drilling operations on the workpiece to be processed. Its operation depends on the movement and positioning of the gantry and completes precise processing in conjunction with the limiting mechanism. Motor 4: Motor 4 is fixedly installed in the inner wall of the processing platform 1 and is the power source of the entire limit mechanism. It drives the worm 5 to rotate through the output end, converting electrical energy into mechanical energy, and providing power for the movement of subsequent components such as worm wheel 6 and transmission roller 7. It is the core power component for realizing automatic limit adjustment. Worm 5: Worm 5 is fixed at the output end of motor 4 and receives the power output of motor 4. It transmits the rotational motion of motor 4 to worm wheel 6 through meshing connection, realizing the direction and transmission of power. It is a key transmission component connecting motor 4 and subsequent transmission components, ensuring efficient power transmission. Worm Gear 6: Worm Gear 6 is meshed with the outer surface of worm 5 and fixedly connected to transmission roller 7. Driven by worm 5, it rotates, converting the horizontal rotational motion of worm 5 into its own vertical axis rotational motion, and at the same time driving transmission roller 7 to rotate synchronously, playing the role of power transmission and motion conversion. Transmission roller 7: The transmission roller 7 is fixedly sleeved on the inner surface of the worm wheel 6 and connected to the disc 8 at its upper end. It rotates under the drive of the worm wheel 6 and transmits the rotational motion of the worm wheel 6 to the disc 8. As an intermediate transmission component, it realizes the transmission of power from the worm wheel 6 to the disc 8 and ensures that the disc 8 rotates synchronously with the worm wheel 6. Disc 8: Disc 8 is fixed on the upper end of transmission roller 7, and four first support rods 9 are installed on its outer surface. When transmission roller 7 drives it to rotate, disc 8 pushes second support rods 10 through the first support rods 9, converting the rotational motion into a force that pushes T-shaped moving block 11 to move. It is a key conversion component for realizing synchronous adjustment of the limit mechanism. First support rod 9: Four first support rods 9 are fixed on the outer surface of the disk 8. One end is connected to the disk 8, and the other end is rotatably connected to the second support rod 10. When the disk 8 rotates, the first support rod 9, through its rotatable connection with the second support rod 10, converts the circular motion of the disk 8 into a pushing or pulling force that drives the second support rod 10, thereby driving the movement of subsequent components. Second support rod 10: Four second support rods 10 are respectively rotatably connected to the end of the first support rod 9 away from the disk 8, and the upper end is rotatably connected to the T-shaped moving block 11. It receives the force transmitted by the first support rod 9. Through the rotatable connection at both ends, the movement of the first support rod 9 is converted into the force that pushes the T-shaped moving block 11 to slide along the slide groove 16, thereby realizing the opening and closing adjustment of the limit mechanism. T-shaped moving block 11: The vertical plate of the T-shaped moving block 11 is slidably sleeved in the slide groove 16, and the horizontal plate is equipped with a sliding roller 12. Under the push of the second support rod 10, it slides along the slide groove 16, driving the sliding roller 12, clamping plate 14 and other components to move synchronously, realizing the initial limit range adjustment of workpieces of different sizes. Its T-shaped structure ensures sliding stability and component installation reliability. Sliding roller 12: The sliding roller 12 is slidably sleeved on the inner wall of the horizontal plate of the T-shaped moving block 11. The two ends are respectively connected to the fixed plate 13 and the clamping plate 14. It can slide along the horizontal plate of the T-shaped moving block 11. Under the action of the spring 15, it pushes the clamping plate 14 to clamp the workpiece. At the same time, it slides itself to provide buffer adjustment space for the clamping plate 14 to adapt to the slight differences on the surface of the workpiece. Fixed plate 13: Fixed plate 13 is fixed to the opposite end of sliding roller 12 and plays a limiting role for sliding roller 12. It prevents sliding roller 12 from slipping out of the horizontal plate of T-shaped moving block 11, ensuring that sliding roller 12 slides within a limited range. At the same time, it provides a mounting support point for spring 15, ensuring that the elastic force of spring 15 can effectively act on clamping plate 14. Clamping plate 14: The clamping plate 14 is fixed at the opposite end of the sliding roller 12 and is a limiting component that directly contacts the workpiece. Under the action of the spring 15, the clamping plate 14 tightly fits the surface of the workpiece, clamps and fixes the workpiece, and prevents the workpiece from shifting during processing. Its position is adjusted with the T-shaped moving block 11 and the sliding roller 12 to adapt to different workpiece sizes. Spring 15: Spring 15 is installed between clamping plate 14 and T-shaped moving block 11. It provides continuous elastic force to clamping plate 14. When clamping plate 14 contacts workpiece, spring 15 deforms and generates elastic force, so that clamping plate 14 clamps workpiece tightly. At the same time, it plays a buffering role to avoid excessive clamping force from damaging workpiece and to ensure the stability and safety of clamping. Slide 16: Slide 16 is formed on the upper surface of the processing platform 1 to provide a sliding track for the vertical plate of the T-shaped moving block 11. It restricts the movement direction of the T-shaped moving block 11, ensures that the four T-shaped moving blocks 11 move synchronously along the preset trajectory, and ensures the accuracy and stability of the limit mechanism adjustment. It is an important guide structure for realizing the centering and limiting of the workpiece.
