Description

Technical Field

[0001] This application relates to the field of hydraulic cylinder parts manufacturing technology, and more specifically, to a clamping device for hydraulic cylinder parts manufacturing. Background Technology

[0002] A hydraulic cylinder, also known as a hydraulic cylinder, is a linear motion actuator whose output force is proportional to the effective area of ​​the piston and the pressure difference between its two sides. It is an energy conversion device that converts hydraulic energy into reciprocating linear motion mechanical energy. It mainly consists of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffer device, and an exhaust device. When manufacturing and processing hydraulic cylinder parts, in order to ensure the stability of the part blanks during processing, it is often necessary to use a clamping device to fix them, so as to ensure the stable and high-precision production and processing of hydraulic cylinder parts.

[0003] A search revealed that patent CN219945371U discloses a clamping device for the production of hydraulic cylinder parts, relating to the field of hydraulic cylinder part manufacturing technology. The device includes: an outer housing; a clamping assembly fixedly installed on the inner surface of the outer housing; an air guide assembly fixedly installed on the front side of the outer housing; a control device fixedly installed on the front right side of the outer housing; and a chip removal and filtering assembly fixedly installed on the bottom back side of the outer housing. This invention, through the clamping assembly, can clamp and fix the hydraulic cylinder part blank for processing, ensuring flexible contact with the part and preventing wear. Furthermore, the outer housing concentrates the debris generated during part processing, and the air guide assembly and chip removal and filtering assembly work together to collect the debris. The coordinated use of related components on the chip removal and filtering assembly makes debris removal more convenient and labor-saving, thereby reducing the operating cost of the device.

[0004] The aforementioned patent collects debris using a single air-guiding fan, which results in dead airflow areas on both sides of the inner wall of the outer casing. This causes debris to accumulate continuously in these areas, significantly increasing the difficulty of cleaning the inside of the outer casing. Furthermore, the accumulated debris may enter the transmission components during equipment operation, exacerbating mechanical wear and hindering normal equipment operation. Utility Model Content

[0005] To address the aforementioned problems, this application provides a clamping device for the production of hydraulic cylinder parts.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Reference Figures 1-9 A clamping device for the production of hydraulic cylinder parts includes a housing 1, a clamping assembly inside the housing 1, and a cleaning assembly at the bottom of the inner side of the housing 1.

[0033] The cleaning assembly includes a scraper 13, and an electric push rod 5 is provided on one side of the inside of the housing 1. The number of scrapers 13 is set to two, and the electric push rod 5 is used to drive the two scrapers 13 to scrape off the debris on the bottom wall of the housing 1.

[0034] Reference Figures 1-9 The cleaning assembly also includes guide fans 3, which are used to directionally clean debris inside the housing 1. Multiple guide fans 3 are provided, positioned on one side of the inner wall of the housing 1. A cavity 4 is formed at the bottom of the housing 1. An electric push rod 5 is fixedly installed on one side of the inner wall of the cavity 4. A slide groove 10 is formed on one side of the cavity 4, and a sliding plate 6 is slidably connected inside the slide groove 10. One side of the sliding plate 6 is fixedly connected to the output end of the electric push rod 5. Racks 7 are fixedly connected to both sides of the sliding plate 6. The interior of the cavity 4 has racks 7 on both sides. A rotating shaft 8 is rotatably connected, and gears 9 are fixedly connected to the outer walls of both rotating shafts 8. Each gear 9 meshes with a corresponding rack 7. Placement slots 11 are provided on both sides of the inner wall of the housing 1. The top of each rack 7 passes through the top of the cavity 4 and is fixedly connected to a connecting seat 12. A slot 14 is provided on one side of each connecting seat 12. A locking block 15 is fixedly connected to one end of each scraper 13. Each slot 14 and the corresponding locking block 15 are inserted into each other with an interference fit. The two connecting seats 12 and the scraper 13 are located inside the corresponding placement slots 11.

[0035] The cleaning component can remove debris produced during the machining of cylinder component blanks. Specifically, after the cylinder component blanks are machined, multiple guide fans 3 are activated to blow away debris adhering to the surfaces of the components and clamping blocks 23. The airflow helps to peel these debris from the machined parts, and the airflow guides the debris towards the collection box, initially guiding its movement. Next, the output end of the electric push rod 5 is extended, pushing the slide plate 6 to slide within the groove 10. The racks 7 on both sides of the slide plate 6 follow the movement of the slide plate. The movement of the rack 7 is due to the meshing of the gear 9 on the rotating shaft 8, which drives the two rotating shafts 8 to rotate, thereby causing the connecting seat 12 at the top of the rack 7 to move synchronously. Since the connecting seat 12 is in interference fit with the locking block 15 through the slot 14, it moves the scraper 13, which will drive the two scrapers 13 to rotate in opposite directions, scraping away the debris accumulated on the bottom wall of the housing 1. With the combined effect of the guide fan 3 blowing away the debris and guiding the airflow direction, and the scraper 13 scraping away the debris on the bottom wall, the debris generated during the processing is thoroughly cleaned, allowing the debris to be collected more efficiently to the designated location.

[0036] When the two scrapers 13 rotate 90 degrees in opposite directions toward the two corresponding placement slots 11, the output end of the electric push rod 5 stops extending. Then, when the output end of the electric push rod 5 begins to retract and pulls the two scrapers 13 back into the corresponding placement slots 11, the electric push rod 5 stops working.

[0037] The cleaning component uses a guide fan 3 to blow away debris from the surface of the parts and clamping block 23 and guide it to the collection box 2. Then, through the transmission of electric push rod 5, rack 7, gear 9, etc., the two scrapers 13 rotate precisely in opposite directions to scrape away debris from the bottom wall of the housing 1. The two work together to achieve comprehensive cleaning of debris, which not only avoids debris accumulation affecting the operation of the device and reduces the frequency of manual cleaning, but also ensures a clean processing environment, helps maintain the processing accuracy and quality of cylinder parts, improves production efficiency and reduces processing costs.

[0038] Reference Figures 1-5 Cylinders 22 are fixedly connected to both outer walls of the housing 1. The output ends of the two cylinders 22 pass through one side of the housing 1 and are fixedly connected to clamping plates 23.

[0039] The cylinder 22 drives the clamping plate 23 to quickly approach or move away, achieving stable and convenient clamping and releasing of the cylinder component blank, which helps to improve clamping efficiency and adapt to different specifications of components.

[0040] Reference Figure 2 , Figure 3 and Figure 7A collection box 2 is provided on one side of the housing 1. A through-hole 16 is provided on one side of the housing 1. An inclined plate 17 is provided on one side of the housing 1. The housing 1 is connected to the collection box 2 through the through-hole 16. A partition 18 is provided on one side of the collection box 2. A slot 20 is provided on one side of the collection box 2. The slot 20 is inserted into the partition 18. A baffle 19 is fixedly connected to the top of the partition 18. A handle 21 is fixedly connected to the top of the baffle 19.

[0041] By setting up a collection box 2, an opening 16, and an inclined plate 17, the inclined plate 17 can guide the debris to fall smoothly into the collection box 2 through the opening 16, achieving orderly collection of debris. Furthermore, through the cooperation of the partition 18, slot 20, baffle 19, and handle 21, the partition 18 can be quickly inserted and removed with the handle 21, facilitating centralized processing of debris in the collection box 2, improving the convenience and efficiency of debris collection and subsequent cleaning, keeping the surrounding environment of the device clean, and reducing the burden of manual cleaning.

[0042] Working principle: After the cylinder component blank is processed, multiple guide fans 3 are first activated to blow away the debris attached to the surface of the component and clamping block 23. The wind force is used to peel these debris off the surface of the processed part, and the airflow from the fans guides the debris into the collection box, initially guiding the movement of the debris. Then, the output end of the electric push rod 5 is extended, and its output end pushes the slide plate 6 to slide in the slide groove 10. The racks 7 on both sides of the slide plate 6 move accordingly. Because the racks 7 and the gears 9 on the rotating shaft 8... The meshing drives the two rotating shafts 8 to rotate, which in turn causes the connecting seat 12 at the top of the rack 7 to move synchronously. Since the connecting seat 12 is in interference fit with the locking block 15 through the slot 14, it moves the scraper 13, which in turn drives the two scrapers 13 to rotate in opposite directions, scraping away the debris accumulated on the bottom wall of the housing 1. With the combined effect of the guide fan 3 blowing away the debris and guiding the airflow, and the scraper 13 scraping away the debris on the bottom wall, the debris generated during the processing is thoroughly cleaned, allowing the debris to be collected more efficiently to the designated location.

[0043] When the two scrapers 13 rotate 90 degrees in opposite directions toward the two corresponding placement slots 11, the output end of the electric push rod 5 stops extending. Then, when the output end of the electric push rod 5 begins to retract and pulls the two scrapers 13 back into the corresponding placement slots 11, the electric push rod 5 stops working.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
