Description

Technical Field

[0001] This disclosure relates to the field of vehicle component handling, and more specifically, to a handling fixture. Background Technology

[0002] The assembly line commonly used in OEMs is a static, integrated assembly process, which includes key components of the lower body, such as the front and rear suspensions, powertrain, and battery pack. These key components are typically supplied in modular form. However, modularly supplied products are generally large in size and weight. During loading, unloading, handling, and off-site transportation, necessary transport packaging and securing measures must be taken based on various factors such as component shape, weight, and road conditions. Forklift and truck suspension systems are designed only for their maximum load capacity, and bumpy roads or large road debris can still cause impacts on transported modular products. If the local rigidity of large, heavy assemblies not in their complete vehicle state is insufficient, it can lead to product deformation and failure to meet the final assembly quality requirements. Utility Model Content

[0003] The purpose of this disclosure is to provide a handling fixture that reduces the possibility of product component deformation when the transport road surface affects the transportation of modularly supplied vehicle components.

[0004] To achieve the above objectives, this disclosure provides a handling fixture, comprising: Base; A tray, positioned above the base, has positioning elements on its upper surface for engaging with the component to be transported; and The support assembly includes a buffer connected between the tray and the base, the buffer being capable of providing a force on the tray in the opposite direction of displacement when the tray is displaced relative to the base.

[0005] Optionally, the positioning element includes: A support base, connected to the pallet, is used to support the parts to be transported; and A positioning post, connected to the support base, is used to extend into and engage with the component to be transported.

[0006] Optionally, the positioning elements are multiple elements arranged at intervals.

[0007] Optionally, the number of support components is multiple, and they are arranged at intervals between the base and the tray.

[0008] Optionally, the buffer includes a shock absorber and a spring arranged adjacent to each other.

[0009] Optionally, there may be multiple shock absorbers and springs, and they may be arranged in a one-to-one correspondence.

[0010] Optionally, the support assembly further includes a core rod and a guide sleeve that are slidable relative to each other in the height direction, wherein the guide sleeve is sleeved on the outside of the core rod, the core rod is disposed on one of the base or the tray, and the guide sleeve is disposed on the other.

[0011] Optionally, the pallet is further provided with two first clamping members disposed opposite each other in a first direction for clamping the component to be transported in the first direction.

[0012] Optionally, the pallet is further provided with two second clamping members disposed opposite each other in the second direction for clamping the component to be transported in the second direction.

[0013] Optionally, two lifting lugs for cooperating with lifting equipment are provided opposite each other at the edge of the base.

[0014] The above technical solution incorporates a support structure with a first buffer between the base and the pallet. This prevents impact deformation of the components being transported due to bumps and impacts, ensuring the accuracy of the components. It also simplifies the transport process, saves time, improves efficiency, and reduces the risk of collisions during transport, achieving stable load-bearing and buffer protection for the components being transported. Furthermore, the positioning elements on the pallet can position the components being transported, restricting their movement path and reducing frictional damage caused by bumps and displacement between the components and the pallet during transport. This further ensures the accuracy of the components being transported and improves the reliability of the transport operation.

[0015] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0020] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" are defined for the actual arrangement direction of the handling fixture during use, and directional terms such as "inner" and "outer" are defined for the outline of the corresponding components. The terms "first," "second," etc., are used to distinguish different components and do not indicate sequence or importance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.

[0021] According to one embodiment of this disclosure, such as Figure 1 and Figure 2 As shown, a handling fixture is provided, including a base 1, a pallet 2, and a support assembly 3. The pallet 2 can be disposed above the base 1, and the upper surface of the pallet 2 is provided with a positioning element 21 for cooperating with the component 4 to be handled. The support assembly 3 may include a buffer element connected between the pallet 2 and the base 1. The buffer element can provide a force on the pallet 2 opposite to the direction of displacement when the pallet 2 is displaced relative to the base 1. When the pallet 2 moves away from the base 1 due to bumps, the buffer element can provide a force that pulls the pallet 2 toward the base 1. When the pallet 2 moves toward the base 1 due to bumps, the buffer element can provide a force that moves the pallet 2 away from the base 1. For example, when the pallet 2 moves upward, the buffer element can provide a force that moves the pallet 2 downward. When the pallet 2 moves downward and to the left at the same time, the buffer element can provide a force that moves the pallet upward and to the right. It should be noted that the component 4 to be handled can be a vehicle frame, front suspension, rear suspension, or a large component such as a powertrain or battery pack. This disclosure does not limit this.

[0022] Through the above technical solution, a support component 3 with a buffer is set between the base 1 and the pallet 2 to avoid impact deformation of the component 4 to be transported due to bumps and impacts, ensuring the accuracy of the component 4 to be transported. At the same time, it simplifies the transportation process, saves time, improves efficiency, and reduces the risk of bumps and collisions during transportation, achieving stable bearing and buffer protection for the component 4 to be transported. In addition, the positioning component 21 set on the pallet 2 can position the component 4 to be transported, restrict its movement path, reduce frictional damage caused by bumps and displacement between the component 4 to be transported and the pallet 2 during transportation, further ensure the accuracy of the component 4 to be transported, and improve the reliability of the transportation operation.

[0023] It should be noted that there can be multiple support components 3, arranged at intervals between the base 1 and the pallet 2. Multiple spaced support components 3 can evenly distribute the weight of the pallet 2 and the component 4 to be transported onto the base 1, reducing the burden on individual support components 3, preventing damage to local structures due to excessive stress, and extending the service life of the tooling. Furthermore, the spaced arrangement allows the support force to cover a larger area of ​​the pallet 2, improving the overall stability of the pallet 2 and reducing pallet 2 tilting caused by center of gravity shift during transport. The number of support components 3 can be determined based on the actual size of the pallet 2 and the specifications of the component 4 to be transported. For example, when the pallet 2 is rectangular, the number of support components 3 can be set to four, all located at the corners of the pallet 2. Alternatively, multiple support components 3 can also be set in the center of the pallet 2; this disclosure does not limit this.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, the positioning element 21 may include a support base 211 and a positioning pin 212. The support base 211 can be connected to the pallet 2 to support the component 4 to be transported. The positioning pin 212 can be connected to the support base 211 to extend into and cooperate with the component 4 to be transported. Here, a positioning hole may be provided on the component 4 to be transported, and the positioning pin 212 may extend into the positioning hole to cooperate with it, thereby limiting the horizontal positioning of the component 4 to ensure the stability of the component 4 during transport. Alternatively, the positioning pin 212 may extend into the bolt holes or mounting holes that are already present on the component 4 to cooperate with it; this disclosure does not limit this.

[0025] In addition, such as Figure 2 As shown, the positioning element 21 can also be multiple spaced apart. Multiple spaced positioning elements 21 can fix the component 4 to be transported from multiple angles and positions, improve the limiting effect of the transport fixture on the component 4 to be transported, thereby improving the stability of the component 4 to be transported on the pallet 2, reducing the shaking amplitude during the transport process, and reducing the risk of friction damage between the component 4 to be transported and the pallet 2.

[0026] According to one embodiment of this disclosure, such as Figure 1 and Figure 2 As shown, the buffer can be composed of multiple components, which can be arranged in a coordinated manner to further enhance the buffering and shock absorption capabilities of the tooling. During the handling process, the component 4 to be handled may face vibrations and impacts of different intensities and frequencies. The arrangement of multiple buffers can improve the anti-bumping ability of the pallet 2, further enhance the buffering effect, and reduce the bumps and impacts experienced by the component 4 to be handled.

[0027] Here, multiple components can be of the same type of buffer, for example, each component can be a shock absorber. Multiple components can also be of different types of buffers; that is, each component can be a shock absorber 31 or a spring 32. Shock absorbers 31 and springs 32 can be arranged adjacent to each other. Shock absorber 31 can be a hydraulic shock absorber or a pneumatic shock absorber. Specifically, it can be a piston rod combined with a hydraulic cylinder or a pneumatic cylinder structure; this disclosure does not limit this. Shock absorber 31 can provide stable support for the tray 2, and can also absorb vibration energy through viscous damping, rapidly attenuating vibration. It can quickly suppress the reciprocating motion of the tray 2 after an impact, avoiding resonance. Spring 32 has good elastic deformation capability and can absorb most of the impact force through its own extension and contraction, playing a buffering role. Spring 32 can absorb impact energy through elastic deformation, but its energy dissipation rate is lower than that of shock absorber 31. Shock absorber 31 can dissipate energy quickly, but its rigidity is stronger than that of spring 32. Therefore, combining the two components for buffering can simultaneously obtain the advantages of both components and improve the buffering effect.

[0028] In addition, in each buffer component, there can be multiple shock absorbers 31 and springs 32, and the two are set in a one-to-one correspondence. In this way, the buffering effect between the tray 2 and the base 1 can be effectively improved.

[0029] According to one embodiment of this disclosure, such as Figure 1 and Figure 2 As shown, the support assembly 3 may further include a core rod 33 and a guide sleeve 34 that can slide relative to each other along the height direction. The guide sleeve 34 can be sleeved on the outside of the core rod 33. The core rod 33 is disposed on either the base 1 or the tray 2, and the guide sleeve 34 is disposed on the other. Specifically, the core rod 33 can be disposed on the tray 2 and the guide sleeve 34 on the base 1, or vice versa. The relative sliding structure between the core rod 33 and the guide sleeve 34 provides horizontal limitation for the tray 2, thus playing a guiding role. This avoids lateral displacement during the buffering process and improves the uniformity of force distribution on the buffer component.

[0030] Here, a locking mechanism can also be provided between the core rod 33 and the guide sleeve 34. In scenarios with flat surfaces and minimal bumps, such as indoor environments, the pallet 2 experiences less bumping during transport, and the impact on the component 4 fixed on it is correspondingly reduced. In such cases, the buffer plays a less significant role. The core rod 33 and the guide sleeve 34 can be locked together to create a rigid connection between the pallet 2 and the base 1, thereby extending the service life of the buffer. The locking mechanism can be a pin. Both the guide sleeve 34 and the core rod 33 have multiple through holes along their extension direction. By inserting the pin into these through holes, the guide sleeve 34 and the core rod 33 can be locked together.

[0031] According to one embodiment of this disclosure, such as Figure 1 and Figure 2 As shown, the pallet 2 may also be provided with two first clamping members 22 arranged opposite each other in the first direction. These members can be used to clamp the component 4 to be transported in the first direction, thereby preventing the component 4 to be transported from sliding horizontally during transport, improving the fixing effect of the component 4 to be transported, and reducing damage to the component 4 to be transported. The first clamping members 22 can be fixed to the corresponding position of the pallet 2 by bolts according to the size and position of the component 4 to be transported when it has been placed on the pallet 2. Alternatively, they can be clamping plates with springs arranged opposite each other. The springs can provide a force to the clamping plates on the opposite side, so that they can clamp the structure located between the two clamping plates. This disclosure does not limit this. There can be multiple pairs of first clamping members 22, and the lines connecting each pair of first clamping members 22 are parallel lines. This disclosure does not limit this.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, the pallet 2 can also be provided with two second clamping members 23 arranged opposite each other in a second direction for clamping the component 4 to be transported in the second direction. Thus, the first clamping members 22 and the second clamping members 23 are arranged in a crisscrossing manner. Here, the crisscrossing arrangement of the first clamping members 22 and the second clamping members 23 means that the line connecting the two oppositely arranged first clamping members 22 intersects the line connecting the two oppositely arranged second clamping members 23. The included angle between the two lines can be a right angle or an acute angle; this disclosure does not limit this. In this way, the two first clamping members 22 and the two second clamping members 23 clamp the component 4 to be transported from multiple directions, further improving the fixing effect of the component 4 to be transported, preventing horizontal sliding of the component 4 during transport, and reducing damage to the component 4 to be transported.

[0033] The second clamping member 23 can be fixed to the corresponding position on the pallet 2 by bolts when the component 4 to be transported is already placed on the pallet 2, depending on the size and position of the component 4. Alternatively, it can be configured with opposing clamping plates equipped with springs, the springs providing a force that presses against the opposite clamping plates, thus clamping the structure located between the two clamping plates. This disclosure does not limit this. Multiple pairs of second clamping members 23 can also be provided, with the lines connecting each pair of second clamping members 23 being parallel lines. This disclosure does not limit this as well.

[0034] To improve the versatility of handling, such as Figure 1 and Figure 2As shown, two lifting lugs 11 can also be provided at the edge of the base 1 for use with lifting equipment. The design of the lifting lugs 11 enables the handling fixture to quickly cooperate with lifting equipment such as cranes and forklifts to achieve mechanized handling of lifting and hoisting. Here, when the area of ​​the pallet 2 is smaller than the area of ​​the base 1, that is, when the pallet 2 is located in the middle of the base 1, the lifting lugs 11 can be located at the edge of the upper surface of the base 1. When the area of ​​the pallet 2 is equal to the area of ​​the base 1, the lifting lugs 11 can be located at the side edge of the base 1, and this disclosure does not limit this.

[0036] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0037] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
