Description

Technical Field

[0001] This invention belongs to the field of automotive parts processing technology, specifically a buffer rack structure for automotive parts processing workpieces. Background Technology

[0002] With the rapid development of the automotive manufacturing industry and the widespread adoption of automated production lines, the requirements for processing precision, production efficiency, and material flow management of automotive parts are constantly increasing. Rod-shaped workpieces, as core components of automotive chassis, transmission systems, and steering systems, are characterized by diverse length specifications, high surface precision requirements, and complex processing procedures. Between multiple processes such as turning, grinding, heat treatment, painting, and final assembly, extensive transfers, temporary storage, and cycle time buffering are needed to balance the differences in processing speed between processes and avoid production line congestion or downtime. Buffer racks, as key tooling for material buffering between processes, directly affect the processing quality, production efficiency, and workshop management costs of automotive parts due to their structural rationality, clamping stability, ease of operation, and space utilization.

[0003] Currently, most traditional rod-shaped workpiece buffer devices use simple fixed brackets, open racks, or ordinary pallets, which have many obvious shortcomings in actual production use: First, most buffer racks lack reliable clamping and limiting structures. The rod-shaped workpieces are simply placed on the support surface, and they are prone to rolling, shifting, colliding and squeezing during transportation or storage, resulting in defects such as scratches, dents, and deformation on the workpiece surface, which seriously affects the dimensional accuracy and appearance quality of precision workpieces; Second, buffer racks with clamping functions mostly use motor-driven, pneumatic clamping, or manual bolt locking methods, which are not only complex in structure and high in manufacturing cost, but also require external power or air supply, limiting installation and usage scenarios.

[0050] Example

[0051] Please see Figures 1-6 As shown, the present invention provides a technical solution: a buffer rack structure for processing automotive parts, comprising:

[0052] Support frame 1 is used to support rod-shaped workpieces;

[0053] The self-locking mechanism includes a clamp 201 slidably connected to the support frame 1 for limiting the rod;

[0054] The unlocking structure includes a pull rod 302 that slides through the support frame 1 and is used to unlock the fixed clamping plate 201;

[0055] The splicing component includes a splicing groove 401 arranged on the support frame 1 for splicing multiple sets of support frames 1.

[0056] The system features automatic clamping and fixing of rod-shaped workpieces via a self-locking mechanism, rapid release and removal of workpieces via an unlocking structure, and multi-frame stacking via splicing components. It integrates the functions of temporary storage, positioning, unlocking, and three-dimensional storage of rod-shaped workpieces, combining the three core functions of clamping, unlocking, and splicing. The system is simple in structure, easy to use, and meets the needs of temporary storage and circulation on the automotive rod-shaped parts processing line.

[0057] In this embodiment, specifically: the self-locking mechanism further includes: a movable rod 202, fixedly arranged on one side of the clamping plate 201, used to control the movement of the clamping plate 201, and the movable rod 202 is slidably connected to the support frame 1; a side oil cavity 203, opened and arranged in the support frame 1, used to accommodate the movable rod 202, and one end of the movable rod 202 is piston-connected in the side oil cavity 203; a compression spring 204, sleeved on one end of the movable rod 202 in the side oil cavity 203, with one end fixedly arranged on the support frame 1 and the other end fixedly arranged on the movable rod 202; and an oil supply pipe 205, opened and arranged in the support frame 1.

[0058] It should be noted that the clamping plate 201 is fixedly connected to the movable rod 202. The end of the movable rod 202 is in the form of a piston and engages with the side oil chamber 203. The oil pressure pushes the movable rod 202 to move the clamping plate 201. The compression spring 204 provides the restoring force for the movable rod 202. The oil supply pipe 205 is used for the directional delivery of hydraulic oil, forming a hydraulically driven clamping and restoring transmission structure. The hydraulic and spring are used for driving, resulting in uniform clamping force and smooth operation. Reliable transmission can be achieved without the need for a motor or cylinder.

[0059] In this embodiment, specifically: the clamping plate 201 is provided in two sets, and is arranged opposite to each other on the support frame 1.

[0060] It should also be understood that the two sets of clamping plates 201 are arranged opposite to each other on the support frame 1. Under the action of hydraulic pressure, they synchronously close towards the center, clamping and limiting the rod-shaped workpiece from both sides at the same time. The symmetrical clamping makes the workpiece subjected to balanced force, accurate positioning, and not easy to deviate or roll. It is suitable for the stable storage of long rod-shaped auto parts.

[0061] In this embodiment, specifically: the bottom of the clamping plate 201 is T-shaped, the support frame 1 is provided with a matching T-shaped groove, and the upper end of the clamping plate 201 is provided with a slot, and a rubber layer is provided in the slot.

[0062] In addition, the bottom of the clamping plate 201 adopts a T-shaped structure that slides in conjunction with the T-shaped groove of the support frame 1 to ensure that the clamping plate 201 moves smoothly and does not derail; the upper end of the clamping plate 201 is provided with a slot and a rubber layer is added to fit in close contact with the surface of the rod-shaped workpiece, which improves the movement accuracy and stability of the clamping plate 201. The rubber layer plays a role in anti-slip, buffering and anti-scratch, protecting the appearance and dimensional accuracy of the precision workpiece.

[0063] In this embodiment, the self-locking mechanism specifically includes: a main oil chamber 206, which is disposed on the support frame 1; a pressure rod 207, which is slidably connected to the support frame 1, and the lower end of the pressure rod 207 is piston-connected to the main oil chamber 206; a return spring 208, which is sleeved on the lower end of the pressure rod 207, with its upper end fixedly disposed on the support frame 1 and its lower end fixedly disposed on the pressure rod 207; and a one-way valve 209, which is disposed on the lower end of the pressure rod 207.

[0064] The workpiece's own weight presses down on the pressure rod 207, which moves down along the main oil chamber 206 and squeezes the hydraulic oil. The return spring 208 is used to lift and reset the pressure rod 207. The one-way valve 209 controls the unidirectional flow of the oil to prevent backflow after clamping. The workpiece's own weight can generate the clamping driving force, achieving self-locking without power. The one-way valve 209 ensures that the clamped state does not loosen, making it safe and reliable.

[0065] In this embodiment, specifically: the lower ends of the side oil chamber 203 and the main oil chamber 206 are connected through an oil supply pipe 205.

[0066] It should be noted that the lower end of the main oil chamber 206 is connected to the lower ends of the two side oil chambers 203 through the oil supply pipe 205. When the pressure rod 207 is pressed down, the oil inside the main oil chamber 206 enters the two side oil chambers 203 simultaneously through the oil supply pipe 205, pushing the movable rod 202 and the clamping plate 201 to move. The oil circuit is smoothly connected, the pressure is transmitted synchronously, and the two clamping plates 201 close at the same time, with consistent clamping action and high positioning accuracy.

[0067] In this embodiment, the unlocking structure further includes: an oil return pipe 301, which is provided on the support frame 1; an oil passage hole 303, which is provided at both ends of the pull rod 302, for controlling the opening and closing of the oil return pipe 301; and a tension spring 304, which is fixedly provided on the support frame 1 at one end and fixedly provided on the pull rod 302 at the other end.

[0068] In addition, the return oil pipe 301 connects the main oil chamber 206 and the upper end of the side oil chamber 203. The pull rod 302 slides laterally and controls the opening and closing of the return oil pipe 301 through the oil passage 303. The tension spring 304 makes the pull rod 302 automatically reset after being released. The oil circuit can be switched by simply pulling the pull rod 302, realizing one-button unlocking.

[0069] In this embodiment, specifically: the upper ends of the side oil chamber 203 and the main oil chamber 206 are connected through the return oil pipe 301.

[0070] It should also be understood that the upper end of the side oil chamber 203 and the main oil chamber 206 are connected by the return oil pipe 301. When unlocking, the return oil pipe 301 is open, and the oil in the side oil chamber 203 can flow back to the main oil chamber 206, so that the oil pressure is unloaded and the clamping plate 201 is loosened, forming a complete closed hydraulic circuit, with the clamping and unlocking oil circuits being independent.

[0071] In this embodiment, specifically: the splicing component further includes: a splicing rod 402, which is fixedly arranged at the lower end of the support frame 1 and snapped into the splicing groove 401 opened in another set of support frames 1; a locking bolt 403, which is threaded through and connected to the support frame 1, and is used to limit the splicing rod 402 after insertion; and a locking hole 404, which is opened at the lower end of the splicing rod 402, and the locking bolt 403 is snapped into the locking hole 404.

[0072] The splicing rod 402 at the bottom of the frame is inserted into the splicing slot 401 at the top of another frame. The locking bolt 403 is tightened so that it is locked into the locking hole 404 of the splicing rod 402, thereby achieving positioning and locking of the upper and lower frames. The splicing positioning is accurate, the connection is firm, and the disassembly and assembly are quick. The storage space can be freely expanded according to the needs of the site.

[0073] In this embodiment, specifically: four sets of splicing slots 401 and four sets of splicing rods 402 are provided.

[0074] Working principle or structural principle: When in use, the rod-shaped workpiece to be stored is placed between the two sets of clamping plates 201 on the support frame 1. The workpiece's own weight will act downward on the pressure rod 207, pushing the pressure rod 207 to slide downward along the main oil chamber 206 on the support frame 1. The piston structure at the lower end of the pressure rod 207 squeezes the hydraulic oil inside the main oil chamber 206, causing the hydraulic oil to be transported to the side oil chambers 203 on both sides through the oil supply pipe 205. The oil pressure pushes the movable rod 202 in the side oil chamber 203 to move outward, thereby driving the two sets of clamping plates 201 to close in opposite directions along the T-shaped groove on the support frame 1, stably clamping and positioning the rod-shaped workpiece. At the same time, the one-way valve 209 set at the lower end of the pressure rod 207 can prevent the hydraulic oil from flowing back, keeping the clamping plates 201 in a clamped state, achieving the effect of automatic locking by relying on the workpiece's own weight.

[0075] When the workpiece needs to be removed, the pull rod 302 on the support frame 1 is pulled outward, aligning the oil passages 303 at both ends of the pull rod 302 with the return oil pipe 301 inside the support frame 1. The side oil chamber 203 and the main oil chamber 206 form a circuit through the return oil pipe 301. The movable rod 202, through the rebound action of the compression spring 204, pushes the hydraulic oil in the side oil chamber 203 back into the upper end of the main oil chamber 206 through the return oil pipe 301. The clamping plate 201 automatically opens, releasing the clamping constraint on the workpiece. At this time, the pressure... The rod 207 is still under pressure from the workpiece. After the workpiece is removed, the pressure rod 207 moves upward and resets due to the action of the return spring 208. At the same time as the pressure rod 207 moves upward, the hydraulic oil at the upper end of the main oil chamber 206 is squeezed into the lower end through the action of the one-way valve 209, thereby restoring it to the initial position. After the pull rod 302 is released, the pull rod 302 automatically resets under the action of the tension spring 304. The oil passage 303 and the return oil pipe 301 are staggered, the return oil pipe 301 is closed, and the device returns to the self-locking state.

[0076] Multiple support frames 1 can be combined and used by splicing them together. Align the splicing rod 402 at the bottom of one support frame 1 with the splicing groove 401 at the top of another support frame 1, and then tighten the locking bolt 403 on the support frame 1 so that the end of the locking bolt 403 is inserted into the locking hole 404 on the splicing rod 402. This completes the firm splicing and positioning of multiple sets of support frames 1, quickly forming a multi-layer three-dimensional buffer storage structure, realizing stable clamping, safe temporary storage and efficient three-dimensional storage of rod-shaped workpieces.
