Description

Technical Field

[0001] This utility model relates to a skateboard support adjustment mechanism in an automobile factory, specifically to a rear support adjustment mechanism for the bottom of a skateboard and a skateboard. Background Technology

[0002] Slide production lines are widely used in automobile assembly plants. Producing multiple car models on the same line is a common production model adopted by various automakers today, necessitating automated adjustment of the slide supports for each model. Traditionally, the adjustment mechanism is located directly above the slide, occupying a separate workstation several stations before the transfer station. This requires pre-judging the car model to be produced, which can easily lead to errors, especially if several pre-adjusted slides are not used during holidays, resulting in data loss. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a rear support adjustment mechanism for the bottom of a skateboard and a skateboard itself. By arranging the rear support adjustment mechanism at the bottom of the skateboard, vehicle model judgment and rear support adjustment can be achieved at the transition point.

[0004] To solve the above-mentioned technical problems, this utility model provides a rear support adjustment mechanism for the bottom of a skateboard, including a bottom frame. A linear guide rail and multiple detection switches are provided on the bottom frame. The multiple detection switches are used to detect the position of the rear support of the skateboard. A sliding bracket is provided on the linear guide rail. A lifting mechanism and a driving mechanism are provided on the sliding bracket. The driving mechanism is used to drive the sliding bracket and the lifting mechanism to move along the linear guide rail. The lifting mechanism is used to cooperate with the connecting shaft of the rear support to lift the connecting shaft, thereby unlocking the rear support of the skateboard from the skateboard and adjusting the position of the rear support.

[0005] In some embodiments, the top of the lifting mechanism is provided with a coupling groove for coupling with a coupling shaft, and the upper end of the coupling groove is provided with a chamfer.

[0006] In some embodiments, the mating groove is fitted to the mating shaft on both sides parallel to the linear guide rail, and a gap is provided between the mating groove and the mating shaft on both sides perpendicular to the linear guide rail.

[0007] In some embodiments, the drive mechanism includes a motor, a rack is provided on the bottom frame, and a gear on the output shaft of the motor engages with the rack to drive the sliding bracket to move along a linear guide rail.

[0008] In some embodiments, a coding ruler detection mechanism is provided on the bottom frame, which is used to verify the actual position of the sliding bracket.

[0009] In some embodiments, the lifting mechanism is provided with two position switches, which are used to detect whether the cylinder has been lifted to the correct position and lowered to the correct position, respectively.

[0010] On the other hand, this utility model provides a skateboard for cooperating with the rear support adjustment mechanism at the bottom of the skateboard. The skateboard is provided with slide rails and slide grooves. Two slide rails are provided, and the slide grooves are arranged in parallel between the two slide rails. Positioning teeth are provided on both sides of the skateboard near the slide grooves. A rear support is slidably provided on the slide rails. A connecting shaft is slidably elastically provided in the middle of the rear support. One end of the connecting shaft extends downward into the slide groove for cooperating with the lifting mechanism. The connecting shaft is provided with mating teeth that cooperate with the positioning teeth.

[0011] In some embodiments, a sliding hole is provided in the middle of the rear support, a connecting shaft is slidably arranged in the sliding hole, a spring is sleeved on the connecting shaft, a positioning plate is fixedly arranged on the connecting shaft, one end of the spring abuts against the rear support, and the other end of the spring abuts against the positioning plate, pressing the positioning plate onto the positioning teeth, and a mating tooth is provided on the lower surface of the positioning plate, the mating tooth meshing with the positioning tooth.

[0012] In some embodiments, the end of the connecting shaft that mates with the lifting mechanism is chamfered.

[0013] In some embodiments, a signal plate is provided on the coupling shaft, the signal plate being used to cooperate with a detection switch.

[0014] The beneficial effects of this utility model are as follows: 1. The rear support adjustment mechanism of this utility model is directly arranged under the slide plate, without the need to occupy a separate workstation, thus optimizing the overall layout, reducing the equipment footprint, and making it suitable for production environments with limited space.

[0015] 2. The lifting mechanism of this utility model simultaneously unlocks the rear support and the sliding plate, and connects the rear support and the rear support adjustment mechanism, when lifting the connecting shaft, simplifying the operation process. It reduces the number of mechanism movements, lowers control complexity, and improves adjustment reliability.

[0016] 3. The lifting mechanism of this utility model adopts an oblong structure for its connecting groove. Its width along the direction parallel to the linear guide rail is small, fitting snugly against the connecting shaft, ensuring the accuracy of the rear support position adjustment when the sliding bracket moves. The connecting groove has a larger width along the direction perpendicular to the linear guide rail, with a gap between it and the connecting shaft, which can accommodate errors during actual installation and operation, enhancing the system's adaptability and stability.

Detailed Implementation

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] In the prior art, the rear support 14 and the slide plate 1 are locked together using a locking groove mechanism. This invention improves upon this by using a toothed plate for locking. Figure 1 , 2 As shown, the rear support adjustment mechanism 2 of this utility model is arranged below the slide plate 1, as follows. Figure 3 , 4 As shown in Figure 5, the slide plate 1 is provided with slide rails 11 and slide grooves 12. Two slide rails 11 are provided, and the slide grooves 12 are arranged parallel between the two slide rails 11. Positioning teeth 13 are provided on both sides of the slide plate 1 near the slide grooves 12. A rear support 14 is slidably mounted on the slide rails 11. The rear support 14 is used to support the rear skirt of the vehicle body, as shown in Figure 5. Figure 6, 7 As shown, a sliding hole is opened in the middle of the rear support 14, and a connecting shaft 15 is slidably installed in the sliding hole. One end of the connecting shaft 15 passes through the sliding groove 12 and is used to cooperate with the lifting mechanism 25. A signal plate 18 is installed at the end of the connecting shaft 15 that passes through the sliding groove 12. A spring 16 is sleeved on the connecting shaft 15, and a positioning plate 17 is fixedly installed on the connecting shaft 15. One end of the spring 16 abuts against the rear support 14, and the other end of the spring 16 abuts against the positioning plate 17, pressing the positioning plate 17 onto the positioning teeth 13. The lower surface of the positioning plate 17 is provided with mating teeth, which mesh with the positioning teeth 13.

[0021] Under the action of spring 16, the positioning plate 17 of the connecting shaft 15 meshes with the positioning tooth 13, preventing the connecting shaft 15 from moving relative to the slide plate 1. Since the connecting shaft 15 is arranged in the sliding hole of the rear support 14, the rear support 14 cannot move relative to the slide plate 1. When it is necessary to adjust the position of the rear support 14, the connecting shaft 15 is lifted by the rear support adjustment mechanism 2, causing the positioning plate 17 to squeeze the spring 16 and rise, causing the mating tooth to separate from the positioning tooth 13. At this time, the rear support 14 can be moved to adjust its position, thereby adapting to different vehicle models.

[0022] Because the rear support 14 and the slide plate 1 are locked together using a toothed plate structure, the lifting displacement required to release the lock has been adjusted from the original 30mm+ to approximately 5mm, i.e., a 5mm lift. This allows the positioning plate 17 to disengage from the positioning teeth 13, facilitating the adjustment mechanism to switch between the locking and unlocking states with a smaller lifting stroke. Of course, the lifting distance depends on the specific design of the positioning teeth 13.

[0023] like Figure 8 , 11 As shown, the rear support adjustment mechanism 2 includes a bottom frame 21, on which a linear guide rail 22 and multiple detection switches 23 are mounted. The multiple detection switches 23 are used to detect the position of the slide plate 1. A sliding bracket 24 is mounted on the linear guide rail 22. A lifting mechanism 25 and a drive mechanism 26 are mounted on the sliding bracket 24. The drive mechanism 26 is a motor and is used to drive the sliding bracket 24 to move along the linear guide rail 22. The motor is equipped with an encoder to actively calculate the required displacement. The lifting mechanism 25 is a cylinder and is used to cooperate with the connecting shaft 15 of the slide plate 1 to lift the connecting shaft 15, thereby unlocking the rear support 14 of the slide plate 1 from the slide plate 1.

[0024] After the lifting mechanism 25 of this utility model is lifted, the rear support 14 is connected to the rear support adjustment mechanism 2, and the locking of the rear support 14 and the positioning tooth 13 on the slide plate 1 is released. One action realizes two functions.

[0025] like Figure 9As shown, the top of the lifting mechanism 25 is provided with a connecting groove 251, which is used to cooperate with the connecting shaft 15. The upper end of the connecting groove 251 is provided with a chamfer to facilitate the connection with the connecting shaft 15.

[0026] like Figure 9 As shown, the connecting groove 251 has an oblong structure, that is, the width of the connecting groove 251 along the direction parallel to the linear guide 22 is smaller than the width of the connecting groove 251 along the direction perpendicular to the linear guide 22. This ensures that after the connecting groove 251 is connected to the connecting shaft 15, the connecting groove 251 fits against the connecting shaft 15 on both sides parallel to the linear guide 22. This ensures that the position of the support 14 is highly accurate when the sliding bracket 24 moves and adjusts along the linear guide 22. A gap is set between the connecting groove 251 and the connecting shaft 15 on both sides perpendicular to the linear guide 22. The gap can be set to be large to cope with actual errors.

[0027] like Figure 8 As shown, a rack 27 is provided on the bottom frame 21, and the motor cooperates with the rack 27 to drive the sliding bracket 24 to move along the linear guide rail 22.

[0028] like Figure 11 As shown, a coding scale detection mechanism 28 is installed on the bottom frame 21. The coding scale detection mechanism 28 is used to verify the actual position of the sliding bracket 24. If the actual position exceeds the error range, an alarm is triggered or the mechanism is actively adjusted to correct it. The coding scale detection mechanism 28 is an existing structure.

[0029] like Figure 11 As shown, two position switches 29 are provided on the lifting mechanism 25. The two position switches 29 are used to detect whether the cylinder has been lifted and lowered to the correct positions.

[0030] The working principle of the rear support adjustment mechanism 2 is as follows: After the slide plate 1 enters the adjustment station (transfer station), the clamps on the slide plate 1 line clamp and position the slide plate 1. One of the detection switches 23 detects the numbering plate 18, and the drive mechanism 26 controls the sliding bracket 24 to move to the corresponding position, so that the lifting mechanism 25 is located directly below the connecting shaft 15.

[0031] After the vehicle model information is read, if the position of the rear support 14 matches the required position for the vehicle model, the position of the rear support 14 does not need to be adjusted. If they do not match, the sliding bracket 24 first moves to the position of the rear support 14. The accuracy of the position is ensured by the encoder detection mechanism 28. Then, the cylinder of the lifting mechanism 25 rises, pushing the coupling shaft 15 upward. The positioning plate 17 compresses the spring 16, and the positioning plate 17 separates from the positioning teeth 13, allowing the rear support 14 to move relative to the slide plate 1. Subsequently, the drive mechanism 26 drives the sliding bracket 24 and the rear support 14 to the target position of the rear support 14 required by the vehicle model. After the operation command is completed, if the actual position fed back by the encoder detection mechanism 28 is within the tolerance range, the cylinder of the lifting mechanism 25 descends, and the coupling shaft 15 descends accordingly. The positioning plate 17 re-engages with the positioning teeth 13 under the action of the spring 16, completing the locking.

[0032] The rear support adjustment mechanism 2 of this invention is located below the slide plate 1, and the rear support 14 is adjusted at the adapter position. Vehicle model recognition is also performed at the adapter position. After recognizing the vehicle model, the adapter is directly transferred, avoiding the problem of data loss. Furthermore, the rear support adjustment mechanism 2 is located below the slide plate 1 and does not occupy a separate workstation.

[0033] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
