Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and more specifically, to a precision grinding equipment for processing hydraulic cylinder parts for engineering machinery vehicles. Background Technology

[0002] In the manufacturing process of hydraulic cylinders for construction machinery vehicles, components (such as piston rods and cylinder barrels) usually need to undergo precision grinding to ensure their surface finish, dimensional accuracy, and sealing performance.

[0003] Based on the above, the inventors have discovered that traditional precision grinding equipment typically uses metal jaws or mechanical clamping to hold and fix parts during processing. These methods are generally difficult to control the clamping force. If the clamping force is too high, it is easy to leave indentations or scratches on precision parts, affecting product quality. If the clamping force is too low, the parts cannot be clamped, affecting the grinding operation and making it inconvenient to use. At the same time, fine metal dust is usually generated during the precision grinding process. Traditional precision grinding equipment mostly uses dust removal fans for dust removal, and the dust removal port is usually fixed and difficult to dynamically adjust with the position of the grinding head, resulting in dust dispersion and poor dust removal effect. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a precision grinding equipment for processing hydraulic cylinder parts for engineering machinery vehicles, in order to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a precision grinding equipment for processing hydraulic cylinder parts for engineering machinery vehicles. It can use a lifting cylinder to drive the grinding mechanism to move upward and gradually approach the parts for grinding operations. An electrostatic adsorption plate is used to adsorb and collect the dust generated during grinding, greatly improving the dust removal effect. At the same time, a tensioning airbag is added, and the inflation and deflation valve are used to control the expansion and contraction of the tensioning airbag to wrap the end of the parts, thereby fixing the parts and preventing indentations or scratches on precision parts, ensuring product quality.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A precision grinding equipment for machining hydraulic cylinder parts for engineering machinery vehicles includes a base, a lower guide frame fixedly connected to the top of the base, an upper guide frame fixedly connected to the top of the lower guide frame, a movable frame slidably connected to the outer periphery of the lower guide frame, two lifting cylinders vertically mounted on the movable frame, and a dust collection groove fixedly connected between the tops of the two lifting cylinders. Electrostatic adsorption plates are fixedly connected to both ends of the dust collection groove, and a grinding mechanism is provided in the middle of the dust collection groove. A slide block is slidably connected to the outer periphery of the upper guide frame, and a movable seat is fixedly connected to the top of the slide block. A fixed seat is fixedly connected to the top of one end of the base. Both the movable seat and the fixed seat are rotatably connected to a positioning plate via a pin, and a tensioning airbag is installed inside the positioning plate.

[0009] Furthermore, the two electrostatic adsorption plates are relatively symmetrical and are arranged at an angle.

[0010] Furthermore, the polishing mechanism includes a polishing motor fixedly installed at the bottom of the dust collection tank, the output shaft of the polishing motor extending to the top of the dust collection tank, and connected to a polishing head via a key.

[0011] Furthermore, a support is fixedly connected to the top of the base, and two pulleys are rotatably connected to the top of the two supports via pins. The two pulleys are connected by a synchronous belt drive. The outer periphery of the synchronous belt is fixedly connected to the outer periphery of the moving frame via a fixing member. A servo motor is installed at the bottom of one of the supports, and the output shaft of the servo motor is connected to the corresponding pin drive via a coupling.

[0012] Furthermore, a drive motor is mounted on the top of the fixed base, and the drive motor is connected to the pin shaft on the fixed base via a coupling.

[0013] Furthermore, a positioning cylinder is fixedly connected to one end of the upper guide frame, and the output end of the positioning cylinder is fixedly connected to one side of the slide.

[0014] Furthermore, a connecting tube is fixed to and connected to the outer periphery of the tensioning airbag, one end of which extends to the outside of the positioning plate and is fixedly installed with an inflatable airbag, and a deflation valve is installed on the inflatable airbag.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this scheme, by setting up the lifting cylinder, the lifting cylinder can drive the grinding mechanism to move up, so that the grinding head gradually approaches the parts and performs grinding operations. The two electrostatic adsorption plates are symmetrical to each other and can generate electrostatic adsorption force after being energized. When they approach the parts during the grinding process, the dust generated by the grinding head can be quickly adsorbed and collected, greatly improving its dust removal effect.

[0018] (2) In this solution, by adding a tensioning airbag and coordinating the inflation airbag and deflation valve to control the expansion and contraction of the tensioning airbag, after placing the end of the accessory inside the tensioning airbag, the inflation airbag is pressed to inflate the tensioning airbag, so that the end of the accessory is wrapped by the tensioning airbag, thus fixing the accessory. During the fixing process of the tensioning airbag, the tensioning airbag is a flexible material, which can avoid leaving indentations or scratches on precision accessories, thus ensuring the quality of the product.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0047] Example:

[0048] Please see Figures 1-4 A precision grinding equipment for machining hydraulic cylinder parts for engineering machinery vehicles includes a base 1, a lower guide frame 2 fixedly connected to the top of the base 1, an upper guide frame 3 fixedly connected to the top of the lower guide frame 2, a movable frame 4 slidably connected to the outer periphery of the lower guide frame 2, two lifting cylinders 5 vertically mounted on the movable frame 4, and a dust collection groove 6 fixedly connected between the tops of the two lifting cylinders 5, electrostatic adsorption plates 7 fixedly connected to both ends of the dust collection groove 6, a grinding mechanism 8 provided in the middle of the dust collection groove 6, a slide seat 9 slidably connected to the outer periphery of the upper guide frame 3, a movable seat 10 fixedly connected to the top of the slide seat 9, a fixed seat 11 fixedly connected to the top of one end of the base 1, and a positioning plate 12 rotatably connected to both the movable seat 10 and the fixed seat 11 via a pin, with a tensioning airbag 13 installed inside the positioning plate 12.

[0049] See Figure 3 Two electrostatic adsorption plates 7 are arranged symmetrically and at an angle. Each electrostatic adsorption plate 7 includes a base plate, an electrode layer, a contact layer, and a conductive coating. During use, the base plate can be made of insulating material, and the electrode layer includes a positive electrode region, a negative electrode region, and an insulating region between the positive and negative electrode regions. When an external power supply device applies voltage, the insulating region between the positive and negative electrode regions becomes a capacitor region. The accumulated charge in the capacitor region generates electrostatic adsorption force. The contact layer is located on the surface of the electrode layer and is designed to prevent electrostatic breakdown.

[0050] See Figure 3The grinding mechanism 8 includes a grinding motor 801 fixedly installed at the bottom of the dust collection tank 6. The output shaft of the grinding motor 801 extends to the top of the dust collection tank 6 and is connected to a grinding head 802 by a key.

[0051] See Figure 2 The top of the base 1 is fixedly connected to a support 14. The tops of the two supports 14 are rotatably connected to pulleys 15 via pins. The two pulleys 15 are connected by a synchronous belt 16. The outer periphery of the synchronous belt 16 is fixedly connected to the outer periphery of the moving frame 4 via a fastener. A servo motor 17 is installed at the bottom of one of the supports 14. The output shaft of the servo motor 17 is connected to the corresponding pin via a coupling. In use, the servo motor 17 drives the pulley 15 to rotate. Under the action of the synchronous belt 16, the grinding mechanism 8 on the moving frame 4 can move horizontally to achieve grinding treatment of various parts.

[0052] See Figure 4 A drive motor 18 is installed on the top of the fixed base 11. The drive motor 18 is connected to the pin shaft on the fixed base 11 through a coupling. In use, after the accessory is fixed by the tension airbag 13, it can be rotated by the drive motor 18.

[0053] See Figure 1 One end of the upper guide frame 3 is fixedly connected to a positioning cylinder 19. The output end of the positioning cylinder 19 is fixedly connected to one side of the slide 9. In use, the position of the positioning plate 12 located on the slide 9 can be adjusted by setting the positioning cylinder 19 so that it can be adapted to accessories of different sizes.

[0054] See Figure 4 A connecting tube 20 is fixed to and connected to the outer periphery of the tensioning airbag 13. One end of the connecting tube 20 extends to the outside of the positioning plate 12 and is fixedly installed with an inflatable airbag 21. An air release valve 22 is installed on the inflatable airbag 21. In use, the tensioning airbag 13 can be inflated by the inflatable airbag 21 to expand and wrap and fix the accessories. The air release valve 22 can release the air in the tensioning airbag 13, making it easy to remove the accessories.

[0055] In use: Place the end of the accessory inside the two positioning plates 12, then press the corresponding inflatable airbag 21 to inflate the tensioning airbag 13. The tensioning airbag 13 expands after inflation, tightly wrapping the end of the accessory within the positioning plate 12, thus securing the accessory. During the securing process, the tensioning airbag 13, being a flexible material, prevents indentations or scratches on precision parts, ensuring product quality. Next, start the grinding motor 801, causing it to drive the grinding head 802 to rotate. Then, the lifting cylinder 5 moves the grinding motor 801 and grinding head 802 upwards on the dust collection tank 6, causing them to... The grinding head 802 performs grinding operations on the parts. At this time, the two electrostatic adsorption plates 7 generate electrostatic adsorption force after being energized. When they are close to the parts during the grinding process, the dust generated by the grinding head 802 can be quickly adsorbed and collected, greatly improving its dust removal effect. At the same time, the servo motor 17 drives the pulley 15, and with the cooperation of the synchronous belt 16, the grinding mechanism 8 on the moving frame 4 can move horizontally. The drive motor 18 drives the positioning plate 12 to rotate the parts, so that all parts of the parts can be fully ground. Finally, after the grinding is completed, the air release valve 22 is pressed to release the air in the tension air bag 13. At this time, the tension air bag 13 contracts, and the parts can be removed.
