Description
Technical Field
[0001] This utility model relates to the field of transfer equipment technology, and in particular to a transfer fixture for KD loose parts with front and rear overhangs. Background Technology
[0002] In the automotive manufacturing industry and related parts production, the efficient transfer of KD (knock-down kit) parts plays a crucial role in the smooth operation of the entire production process. The front and rear suspensions, as important components of KD parts, require particularly careful handling during transfer. These components are not only structurally complex but also demand extremely high precision in vehicle assembly. Timely and safe transfer of these parts to designated workstations ensures production line continuity, reduces downtime caused by untimely parts supply, effectively improves production efficiency, and lowers overall production costs.
[0003] Traditional transport fixtures are mostly designed with fixed dimensions and lack flexible and adjustable structures. However, due to factors such as the diversity of vehicle models and continuous design updates, the specifications of KD (knock-down kit) parts' front and rear overhangs vary greatly. When encountering larger parts, existing fixtures, due to the limited area of the placement plate, cannot provide sufficient load-bearing space, causing difficulties in transport. In such cases, companies often have to frequently change fixtures to accommodate different part sizes, or adopt additional splicing and reinforcement methods, which undoubtedly greatly reduces production efficiency and significantly increases production costs. Therefore, a KD parts front and rear overhang transport fixture is proposed. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a KD loose parts front and rear suspension transfer fixture, which aims to improve the problem that existing fixtures in the prior art cannot provide sufficient load-bearing space due to the limited area of the placement plate.

[0029] 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.
[0030] Reference Figures 1-3This utility model provides an embodiment of a KD (Knock-Down) parts rear-suspension transfer fixture, including a hydraulic forklift 1. The hydraulic forklift 1 is the mobile foundation of the entire transfer fixture, utilizing a hydraulic system to lift and transport goods. It features flexible operation and strong load-bearing capacity, enabling convenient transfer of the fixture and KD parts between different working areas with rear suspension. Four support plates 2 are fixedly connected to the front of the hydraulic forklift 1. The support plates 2 support and fix the placement plate 4. Multiple positioning holes 3 are formed on the surface of the support plates 2. The positioning holes 3 engage with subsequent locking rods 17 to fix and adjust the placement plate 4. A placement plate 4 is provided between the support plates 2. The placement plate 4 is used to place the front and rear overhangs of the KD parts, so as to facilitate the transfer of the front and rear overhangs of the KD parts. Extension components are provided on both the left and right sides of the placement plate 4. The extension components are used to extend the placement plate 4 to adapt to the front and rear overhangs of KD parts of different specifications. A drive component is provided on the front side of the placement plate 4. The drive component is used to drive the extension component to move, so that the extension component can extend or retract. A pressing component is provided at each of the four corners inside the placement plate 4. A fixing component is provided on both the front and rear sides inside the placement plate 4. The pressing component and the fixing component cooperate to fix and loosen the placement plate 4.
[0031] Reference Figure 2 The extension assembly includes two telescopic plates 5. The outer walls of the telescopic plates 5 are slidably connected to the inside of the placement plate 4. By sliding the telescopic plates 5 against the inner wall of the placement plate 4, the placement plate 4 can be extended or retracted. A baffle 6 is fixedly connected to the opposite side of each of the two telescopic plates 5. The baffle 6 is used to block the front and rear overhangs of the KD parts on the placement plate 4 to prevent the KD parts from falling off during transportation. A rack plate 7 is fixedly connected to the opposite side of each of the two telescopic plates 5. The rack plate 7 is used to cooperate with the subsequent gear 10 to generate movement and drive the telescopic plates 5 to slide.
[0032] Reference Figure 3 The drive assembly includes a motor 8 and a battery 9. The motor 8 is fixedly connected to the front side of the placement plate 4 and serves as a power source to provide power to the extension assembly. The battery 9 is fixedly connected to the bottom of the placement plate 4 and is electrically connected to the motor 8. The battery 9 is used to provide power support to the motor 8, thereby ensuring that the motor 8 can work normally. A gear 10 is fixedly connected to the output end of the motor 8, and the rotation generated by the motor 8 drives the gear 10 to rotate.
[0033] Reference Figure 3The extrusion assembly includes four pressing rods 11. The outer wall of each pressing rod 11 is slidably connected to the inside of the placement plate 4. The pressing rods 11 slide inside the placement plate 4, which facilitates the sliding of other components by pressing the pressing rods 11. A first limiting block 12 is fixedly connected to the outer wall of each pressing rod 11. The first limiting block 12 is used to limit the pressing rods 11 and prevent them from sliding out of the placement plate 4. A first spring 13 is fixedly connected to the bottom of the first limiting block 12. The first spring 13 is used to provide elastic force and store elastic potential energy after the pressing rod 11 is pressed. When the external force disappears, the stored potential energy is released, thereby pushing the first limiting block 12 to slide and reset. A wedge block 14 is fixedly connected to the bottom of each pressing rod 11. The wedge block 14 is used to cooperate with the subsequent wedge plate 18 to achieve the effect of pressing the pressing rod 11 to drive the locking rod 17 to slide.
[0034] Reference Figure 3 The fixing component includes a second limiting block 15, the outer wall of which is slidably connected to the inner wall of the placement plate 4. The second limiting block 15 is used to limit the locking rod 17 to prevent the locking rod 17 from sliding excessively and disengaging from the interior of the placement plate 4. A second spring 16 is fixedly connected to one side of the second limiting block 15 to provide elastic force, thereby pushing the second limiting block 15 to reset. The locking rod 17 is fixedly connected to the other side of the second limiting block 15. The locking rod 17 engages with the positioning hole 3 to fix the placement plate 4. An inclined plate 18 is fixedly connected to the outer wall of the locking rod 17. The inclined plate 18 slides under the push of the inclined block 14, further driving the locking rod 17 to slide, thereby releasing the locking rod 17 from the state of engagement with the positioning hole 3.
[0035] Reference Figure 2 The length of the telescopic plate 5 is less than half the length of the placement plate 4, which ensures that the telescopic plate 5 has enough sliding space in the placement plate 4 and avoids interference between the telescopic plate 5 and other components during the extension or retraction process. The rack plate 7 and the gear 10 mesh with each other to ensure that when the gear 10 rotates, it can effectively transmit the rotational motion to the rack plate 7, thereby driving the rack plate 7 to perform linear motion.
[0036] Reference Figure 3 The end of the first spring 13 away from the first limiting block 12 is fixedly connected to the inner wall of the placement plate 4, ensuring that when the first spring 13 releases the stored potential energy, it can effectively push the first limiting block 12 to slide, thereby driving the pressing rod 11 to slide. The inclined block 14 and the inclined plate 18 abut against each other, and the abutment enables the pressing component to convert the vertical pressure into the horizontal thrust, pushing the clamp rod 17 of the fixing component to move.
[0037] Reference Figure 3The locking rod 17 passes through the placement plate 4 and engages with the positioning hole 3. This engagement ensures a stable connection between the support plate 2 and the placement plate 4, guaranteeing the stability of the placement plate 4 during transport. The end of the second spring 16 away from the second limiting block 15 is fixedly connected to the inner wall of the placement plate 4, ensuring that when the second spring 16 releases its stored potential energy, it can effectively push the second limiting block 15 to slide, further driving the locking rod 17 to slide, thus engaging the locking rod 17 with the positioning hole 3.
[0038] Reference Figure 2 The outer wall of the rack plate 7 is slidably connected to the inside of the placement plate 4, ensuring that the rack plate 7 can slide smoothly inside the placement plate 4, thereby pushing the telescopic plate 5 to slide, achieving the effect of extending and retracting the placement plate 4.
[0039] Working principle: When it is necessary to transfer the front and rear suspensions of KD parts, the KD parts to be transferred are placed on the placement plate 4. Then, by pressing and lifting the hydraulic forklift 1, the front and rear suspensions of the KD parts can be transferred. When the specifications of the front and rear suspensions of the KD parts change, the motor 8 is started by powering on. When the motor 8 is powered on, it converts electrical energy into mechanical energy, thereby generating rotation. When the motor 8 rotates, it drives the gear 10 on its output end to rotate. The rotation of the gear 10, through meshing with the rack plate 7, converts the rotational motion into the linear motion of the rack plate 7, thereby driving the telescopic plate 5 to slide, extending or retracting the placement plate 4. At the same time, the pressing rod 11 can also be pressed to slide. When the pressing rod 11 slides, it drives the first limit block 12 to slide, and the sliding of the first limit block 12 controls the inclined block 1. 4. When the pressing rod 11 slides, it also drives the inclined block 14 to slide. The inclined block 14 and the inclined plate 18 abut against each other. Therefore, the downward sliding of the inclined block 14 will drive the inclined plate 18 to move laterally. When the inclined plate 18 slides, it will drive the locking rod 17 to slide, and at the same time drive the second limiting block 15 to slide, and compress the second spring 16, so that the second spring 16 stores potential energy. When the locking rod 17 disengages from the positioning hole 3, the height of the placement plate 4 can be adjusted. Then, the pressing rod 11 is released. At this time, the outer wall disappears, and the first spring 13 and the second spring 16 will release the stored potential energy, thereby pushing the second limiting block 15 and the first limiting block 12 to slide, so that the pressing rod 11 and the locking rod 17 are reset, and the locking rod 17 engages with the positioning hole 3 to fix the placement plate 4.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
