Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a multi-layer clamping mechanism for deburring a forklift. Background Technology

[0002] In modern machining, especially in the automotive parts and transmission systems industries, the fork, as a crucial connecting or transmission component, has a significant impact on the assembly accuracy and operational stability of the entire system due to its surface quality. Deburring is an indispensable step in the fork manufacturing process, primarily aimed at removing burrs and flash remaining on edges, holes, or joints after casting, forging, or machining, ensuring surface finish, assembly accuracy, and operational safety. Traditional fork deburring relies heavily on manual operation or single-station clamping equipment, which is not only inefficient but also struggles to guarantee consistency and processing quality for each workpiece. With the continuous improvement of production automation and intelligence, the industry is gradually adopting dedicated deburring equipment for batch processing of forks and other parts. However, in actual production, existing deburring equipment often suffers from problems such as simple structure, limited clamping capacity, insufficient positioning accuracy, and unstable clamping. Especially when facing the demand for processing multiple varieties and large quantities of forks, traditional clamping methods struggle to achieve efficient multi-station synchronous operations, limiting overall production efficiency and increasing the labor intensity of operators and the risk of processing quality fluctuations.

[0003] Chinese patent discloses a deburring device (publication number: CN 218837097 U) including a worktable, a support, and a grinding assembly, as well as a protective assembly. The protective assembly includes a clamping plate, a mounting shell, a guard, a spring, a locking component, a driving component, and a cleaning component. However, this deburring device suffers from problems such as a small number of items that can be clamped at a time, unstable positioning and clamping, a simple structure, and the inability to achieve efficient synchronous operation of multiple stations, which affects processing efficiency, consistency, and automation level. Therefore, a multi-layer clamping mechanism for a fork deburring device is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems that traditional deburring equipment for segmented forks generally suffers from a small number of clamping operations per operation, unstable positioning and clamping, simple structure, and inability to achieve efficient synchronous operation of multiple stations, which affects processing efficiency, consistency and automation level. Therefore, a multi-layer clamping mechanism for deburring equipment for segmented forks is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The multi-layer clamping mechanism of the deburring equipment for forks of this utility model includes a vertically arranged main frame, characterized in that: the main frame has an embedded rectangular opening at its center, the back of the main frame has a multi-layer window plate corresponding to the embedded rectangular opening, the multi-layer window plate has multiple clamping windows from top to bottom, a multi-layer clamping plate is provided on one side of the multi-layer window plate, the multi-layer clamping plate has multiple square clamping positions for placing fork workpieces, positioning guide rails are provided on both sides of the multi-layer clamping plate and are associated with the multi-layer window plate, and a driving component is provided on the top of the multi-layer clamping plate. The vertical frame and embedded opening structure provides a reasonable spatial layout for deburring, facilitating the entry of machining tools or observation of the internal workpiece status. The multi-layered window plates and clamping windows effectively support and functionally partition the internal clamping structure, which is beneficial for precise positioning during machining. The design of multiple square clamping positions allows the mechanism to clamp multiple fork-type workpieces simultaneously, laying the foundation for batch processing. The associated design of the positioning guide rail and window plates ensures the positional accuracy and structural stability of the clamping plates during movement or fixation. The overall structure adopts a layered and modular design, which facilitates later maintenance, adjustment and expansion.

[0006] Preferably, the driving assembly includes a driving cylinder, which includes a piston cylinder and a piston rod associated with the piston cylinder. One end of the piston rod is provided with a pressure block, which is associated with the top of the multi-layer clamping plate. The cylinder-driven method offers fast response and simple control, making it suitable for use with automated production lines. The linkage design between the piston rod and the pressure block ensures uniform pressure is applied to the entire clamping plate, guaranteeing that all fork-type workpieces at all clamping positions are clamped synchronously. The direct interaction between the pressure block and the top of the clamping plate ensures effective transmission of clamping force, improving the stability of the workpiece during processing.

[0007] Preferably, a connecting block is provided at the center of the top inner wall of the square clamping position, a positioning fixture is provided on one side of the connecting block, a limiting fixture is provided below the positioning fixture, and a segmented fork workpiece is provided between the positioning fixture and the limiting fixture. Through the combined structure of the positioning fixture and the limiting fixture, multi-directional and multi-angle positioning and clamping of the segmented fork workpiece can be achieved, effectively preventing workpiece displacement or rotation during processing. The connecting block serves as the fixed foundation of the fixture, ensuring the structural stability and installation accuracy of the fixture itself. The workpiece is stably clamped between the two fixtures, which not only improves the safety during processing but also ensures the accuracy and consistency of deburring. Preferably, the outer wall of the embedded rectangular opening is provided with a rectangular frame, and the rectangular frame is provided with a plurality of bolt holes for connection. The rectangular frame enhances the structural strength and edge protection of the embedded opening, which helps to maintain the stability of the overall mechanism; the bolt holes enable detachable connection, allowing components such as multi-layer window panels and clamping mechanisms to be easily installed, disassembled and maintained, thus improving the serviceability of the equipment.

[0008] Preferably, the multiple clamping windows on the multi-layer window plate are distributed at intervals along the vertical direction, and each clamping window is vertically aligned with a corresponding square clamping position. This vertically spaced distribution of the clamping windows creates a clear hierarchy in the multi-layer clamping structure, facilitating layer-by-layer or point-by-point operation of the machining tools. The one-to-one correspondence between each clamping window and clamping position ensures that each fork section workpiece can be accurately aligned with the machining area, avoiding offset or misalignment and improving machining accuracy.

[0009] Preferably, both the multi-layer clamping plate and the multi-layer window plate are made of carbon steel. Carbon steel has high strength and rigidity, which can withstand the pressure and vibration generated during the clamping process, ensuring the structural stability of the mechanism in long-term use; carbon steel also has good wear resistance and processing performance, making it suitable for use in industrial-grade deburring environments, and it is not easily deformed or damaged.

[0010] The advantages of this utility model are: This invention provides a multi-layer clamping mechanism specifically for deburring equipment for tow assemblies. Its vertically arranged main frame and embedded rectangular openings provide a reasonable structural space and tool access channel for deburring operations. Combined with multi-layer window plates on the back of the main frame and corresponding clamping windows, it achieves a reasonable layout and functional distinction between the processing and clamping areas. Simultaneously, by setting multi-layer clamping plates with square clamping positions on one side of the window plates, and configuring positioning and limiting fixtures in each clamping position, the tow assemblies can be independently and accurately positioned and securely clamped at multiple levels. This effectively avoids workpiece displacement or posture deviation caused by vibration or impact during processing, improving the accuracy and consistency of deburring. Furthermore, positioning guide rails on both sides of the clamping plates are linked to the window plates, ensuring the positional accuracy and structural stability of the clamping plates during vertical movement or fixing. Qualitatively, in conjunction with the cylinder, piston rod, and pressure block structure in the top drive assembly, the entire clamping plate can be quickly and evenly clamped and fixed, ensuring that all workpieces are in a stable clamping state during processing, thus improving the safety and reliability of the processing. The multi-layer clamping structure design allows the equipment to clamp multiple fork-type workpieces at once, significantly increasing the number of workpieces processed in a single operation and overall work efficiency. At the same time, the clamping plate and window plate are made of carbon steel, which has good structural strength, wear resistance, and deformation resistance, and can adapt to the high-intensity use environment in industrial production, extending the service life of the mechanism and reducing the frequency of maintenance. The overall structure adopts a modular and layered design concept, with reasonable layout and clear functions of each component, which is not only easy to install and debug, but also easy to maintain and expand functions later. Thus, while ensuring processing quality, it achieves efficient, stable, and safe multi-station fork deburring and clamping operations. Attached Figure Description

[0017] 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 scope of protection of the present utility model. Example

[0018] Please see Figure 1-4 As shown, a multi-layer clamping mechanism for a deburring device for a fork includes a vertically arranged main frame 1. The main frame 1 has an embedded rectangular opening 3 at its center, and a multi-layer window plate 10 corresponding to the embedded rectangular opening 3 is located on the back of the main frame 1. The multi-layer window plate 10 has multiple clamping windows 11 from top to bottom. A multi-layer clamping plate 8 is located on one side of the multi-layer window plate 10. The multi-layer clamping plate 8 has multiple square clamping positions 9 for placing fork workpieces 13. Positioning guide rails 7 are located on both sides of the multi-layer clamping plate 8 and are associated with the multi-layer window plate 10. A driving assembly is located at the top of the multi-layer clamping plate 8. The vertical frame and embedded opening structure provides a reasonable spatial layout for deburring, facilitating the entry of processing tools or observation of the internal workpiece status. The multi-layer window plate 10 and clamping window 11 effectively support and functionally partition the internal clamping structure, which is beneficial for precise positioning during processing. The design of multiple square clamping positions 9 allows the mechanism to clamp multiple segmented fork workpieces 13 simultaneously, laying the foundation for batch processing. The associated design of the positioning guide rail 7 and the window plate ensures the positional accuracy and structural stability of the clamping plate during movement or fixation. The overall structure adopts a layered and modular design, which facilitates later maintenance, adjustment and expansion.

[0019] In this embodiment, the driving component includes a driving cylinder, model SMC CQ2B32-100D, which is a commercially available product. The driving cylinder includes a piston cylinder 4 and a piston rod 5 associated with the piston cylinder 4. One end of the piston rod 5 is provided with a pressure block 6, which is associated with the top of the multi-layer clamping plate 8. The cylinder-driven method offers fast response and simple control, making it suitable for use with automated production lines. The linkage design between the piston rod 5 and the pressure block 6 ensures uniform pressure is applied to the entire clamping plate, guaranteeing that all fork workpieces 13 at all clamping positions are clamped synchronously. The direct interaction between the pressure block 6 and the top of the clamping plate ensures effective transmission of clamping force, improving the stability of the workpiece during processing.

[0020] In this embodiment, a connecting block is provided at the center of the top inner wall of the square clamping position 9, a positioning fixture 12 is provided on one side of the connecting block, a limiting fixture 14 is provided below the positioning fixture 12, and a segmented fork workpiece 13 is provided between the positioning fixture 12 and the limiting fixture 14. Through the combined structure of the positioning fixture 12 and the limiting fixture 14, the segmented fork workpiece 13 can be positioned and clamped in multiple directions and at multiple angles, effectively preventing displacement or rotation of the workpiece during processing; the connecting block serves as the fixed foundation of the fixture, ensuring the structural stability and installation accuracy of the fixture itself; the workpiece is stably clamped between the two fixtures, which not only improves the safety of the processing process, but also ensures the accuracy and consistency of deburring processing; In this embodiment, the outer wall of the embedded rectangular opening 3 is provided with a rectangular frame 2, and the rectangular frame 2 is provided with a plurality of bolt holes for connection. The rectangular frame 2 enhances the structural strength and edge protection of the embedded opening, which helps to maintain the stability of the overall mechanism; the bolt holes enable detachable connection, which allows components such as the multi-layer window panel 10 and the clamping mechanism to be easily installed, disassembled and maintained, thereby improving the serviceability of the equipment.

[0021] In this embodiment, multiple clamping windows 11 on the multi-layer window plate 10 are distributed at intervals along the vertical direction, and each clamping window 11 is vertically corresponding to a corresponding square clamping position 9. The vertically spaced distribution of the clamping windows 11 makes the multi-layer clamping structure clearly layered, which is beneficial for the machining tools to operate layer by layer or at fixed points; the one-to-one correspondence between each clamping window 11 and the clamping position ensures that each section workpiece 13 can be accurately aligned with the machining area, avoiding offset or misalignment and improving machining accuracy.

[0022] In this embodiment, both the multi-layer clamping plate 8 and the multi-layer window plate 10 are made of carbon steel. Carbon steel has high strength and rigidity, and can withstand the pressure and vibration generated during the clamping process, ensuring the structural stability of the mechanism in long-term use; carbon steel also has good wear resistance and processing performance, making it suitable for use in industrial-grade deburring environments, and it is not easily deformed or damaged.

[0023] The implementation principle of this embodiment is as follows: During operation, the operator or the feeding device sequentially places the segmented fork workpiece 13 into the square clamping positions 9 of the multi-layer clamping plate 8. Each clamping position is equipped with a connecting block, which is associated with both the positioning fixture 12 and the positioning guide rail 7 for vertical movement. The positioning fixture 12 can be adjusted in position by the connecting block and cooperates with the limiting fixture 14 below. The limiting fixture 14 is designed to be replaceable according to the size of different segmented fork workpieces 13 to accommodate various specifications of workpieces. A certain floating gap is maintained between the positioning fixture 12 and the limiting fixture 14. The operator manually or automatically installs the positioning fixture 12 and the limiting fixture 14 on the upper and lower sides of the workpiece, and they work together to clamp and position the segmented fork workpiece 13 from both above and below or inside and outside directions, ensuring that the segmented fork maintains a fixed posture in the clamping position and preventing displacement during processing.

[0024] Subsequently, the multi-layer clamping plate 8, which clamps the fork workpiece 13, is associated with the multi-layer window plate 10 on the back of the main frame 1 through the positioning guide rails 7 set on both sides, so as to achieve precise positioning and stable guidance of the clamping plate in the vertical direction, and ensure that each clamping position and the corresponding clamping window 11 on the multi-layer window plate 10 are precisely aligned in the vertical direction, providing an accurate positioning basis for subsequent processing.

[0025] After the clamping plate completes the loading and positioning of the workpiece, the drive assembly located at the top of the multi-layer clamping plate 8 begins to operate. The cylinder in this drive assembly, under air pressure, pushes the piston rod 5 downwards. The pressure block 6 at the end of the piston rod 5 contacts the top of the multi-layer clamping plate 8 and applies downward pressure, thereby synchronously clamping and fixing the entire clamping plate and all the segmented fork workpieces 13 on it. During this process, the connecting block moves downwards along with the clamping plate, and the positioning fixture 12 and the limiting fixture 14 cooperate to clamp the workpiece, ensuring that all workpieces are in a stable clamping state during processing, thus improving the safety and reliability of the processing.

[0026] During the processing, the deburring equipment's processing tools deburr each section of the workpiece 13 one by one or simultaneously. Since each clamping window 11 corresponds to a clamping position in the vertical direction, the processing tools can accurately act on the target workpiece without interfering with other workpieces or the mechanism itself.

[0027] After processing is completed, the drive cylinder reverses its movement, the piston rod 5 retracts, and the pressure block 6 releases the pressure on the clamping plate. At this time, the operator or automated device can take out the deburred fork workpiece 13 and replace the corresponding limit fixture 14 according to the specifications of the next batch of workpieces, and then repeat the clamping process.
