[0002] The multi-way valve adopts a unified modular design, providing reliable system solutions for engineering vehicle manufacturers. Users can combine the valve body in different ways according to functional requirements, which is simple and reliable. It can be a simple load-sensitive manual multi-way valve, or an electro-hydraulic proportional control valve with non-saturation function that is independent of load and pump flow.

[0003] After the multi-way valve body casting is cooled and formed, a grinding device is needed to grind the surface of the multi-way valve body casting in order to improve the production quality of the multi-way valve body casting.

[0004] The existing technology has the following problems:

[0005] In actual use, the existing device makes it difficult to adjust the position of the valve body casting during grinding, which means that the grinding disc can only be ground in a fixed position, thus reducing the effectiveness of the device and reducing grinding efficiency. At the same time, it is inconvenient to collect the iron filings generated during grinding, causing the iron filings to be scattered on the installation platform, requiring manual cleaning of the iron filings afterward, which increases the labor intensity of the workers. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A grinding device for machining multi-way valve body castings includes a mounting platform. A moving mechanism is mounted on the upper end of the mounting platform, and a support frame is connected to the upper end of the moving mechanism. Screw sleeves are symmetrically fixed to both sides of the support frame. A screw rod is threaded into the internal part of each screw sleeve. A knob is fixedly connected to the top of the screw rod, and a clamping plate is rotatably mounted on the bottom of the screw rod. A bracket is fixedly mounted at the rear end of the mounting platform.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] like Figure 1-5As shown, this utility model provides a grinding device for processing multi-way valve body castings, including a mounting platform 1. A moving mechanism 2 is mounted on the upper end of the mounting platform 1. A support frame 3 is connected to the upper end of the moving mechanism 2. Screw sleeves 4 are symmetrically fixedly connected to both sides of the support frame 3. A screw rod 5 is threadedly connected inside the screw sleeve 4. A knob 6 is fixedly connected to the top of the screw rod 5. A clamping plate 7 is rotatably mounted on the bottom of the screw rod 5. A bracket 8 is fixedly mounted at the rear end of the mounting platform 1. A dust collection mechanism 9 is mounted on the lower side of the rear end of the bracket 8. A dust collection hood 10 is fixedly connected to the lower side of the front end of the bracket 8. A hydraulic cylinder 11 is fixedly mounted on the top of the bracket 8. A mounting frame 12 is fixedly connected to the bottom of the output rod of the hydraulic cylinder 11. A motor 13 is fixedly mounted inside the mounting frame 12. A grinding disc 14 is driven by the output rod of the motor 13. Side plates 15 are symmetrically fixedly connected to both sides of the mounting frame 12. Limiting rods 23 are symmetrically fixedly connected to the inner wall of the top of the bracket 8.

[0026] The inner side of the clamping plate 7 is glued with a rubber anti-slip pad, and the surface of the side plate 15 is slidably connected to the outside of the side rod 16.

[0027] When clamping the valve body casting with clamping plate 7, the rubber anti-slip pads first contact the two sides of the valve body casting. The rubber anti-slip pads can increase the friction between clamping plate 7 and valve body casting, thereby improving the clamping effect and avoiding clamping marks on valve body casting. When mounting bracket 12 moves up and down, it will drive side plate 15 to slide synchronously on side rod 16, thereby improving the stability of mounting bracket 12 during movement.

[0028] like Figure 3 As shown, the moving mechanism 2 includes a lead screw 21, the two ends of which are rotatably connected to the inner middle of the mounting platform 1. The lead screw 21 is threadedly connected to a threaded seat 22. Limiting rods 23 are symmetrically fixedly installed on the inner front and rear sides of the mounting platform 1. Limiting blocks 24 are slidably installed on the outer side of the limiting rods 23. A handle 25 is rotatably installed on the right end of the mounting platform 1. Multiple sets of through holes are opened in a circular shape on the outer side of the handle 25. Insertion rods 26 are movably inserted into the inside of the through holes. Multiple sets of insertion holes 27 are opened in a circular shape on the right side surface of the mounting platform 1.

[0029] The right end of the lead screw 21 is connected to the left end of the handle 25 for transmission, and the upper ends of the threaded seat 22 and the limiting block 24 are fixedly connected to the lower end of the support frame 3.

[0030] The insertion rod 26 is engaged with the insertion hole 27 and is movably connected.

[0031] When the threaded seat 22 drives the receiving frame to move, the receiving frame will drive the limiting block 24 to slide synchronously on the limiting rod 23, thereby limiting the threaded seat 22 and preventing it from rotating. The inserted rod 26 can pass through the through hole on the handle 25 and be inserted into the insertion hole 27, thereby limiting the handle 25 and preventing the handle 25 from rotating under the influence of external force.

[0032] like Figure 4-5 As shown, the vacuuming mechanism 9 includes a connecting seat 91. One end of the connecting seat 91 is fixedly installed on the lower rear end of the bracket 8. A vacuuming fan 92 is fixedly installed on one side of the upper end of the connecting seat 91. A dust collection box 93 is fixedly connected to the other side of the upper end of the connecting seat 91. A connected vacuuming pipe 94 is fixedly connected to the left side of the dust collection box 93. Positioning frames 95 are symmetrically fixedly connected to the upper and lower inner walls of the dust collection box 93. A filter plate 96 is movably installed inside the positioning frame 95.

[0033] The left end of the vacuum cleaner 92 is connected to the right end of the dust collection box 93 and they are interconnected. The front side of the dust collection box 93 is hinged with a door.

[0034] The top end of the suction pipe 94 passes through the bracket 8 and is fixedly connected to the rear end of the suction hood 10, and they are interconnected.

[0035] The filter plate 96 can filter the iron filings in the dust collection box 93, preventing the iron filings from damaging the dust collector fan 92. By opening the box door, it is convenient to clean the iron filings in the dust collection box 93.

[0036] The working principle of the grinding device for machining multi-way valve body castings will be explained in detail below.

[0037] like Figure 1-5As shown, when using this multi-way valve body casting grinding device, the valve body casting to be ground can first be placed on the support frame 3. Then, the knobs 6 on both sides can be rotated, causing the knobs 6 to drive the screw 5 to rotate within the screw sleeve 4. The screw 5 pushes the clamping plate 7 towards the valve body casting, so that the clamping plate 7 contacts both sides of the valve body casting, thereby positioning and clamping the valve body casting to prevent it from shifting during grinding and affecting the grinding effect. Next, the hydraulic cylinder 11 and the motor 13 can be started. The motor 13 can drive the grinding disc 14 to rotate, while the hydraulic cylinder 11 can push the mounting frame 12 to move downward, so that the mounting frame 12 drives the motor 13 and the grinding disc 14 to move synchronously, thereby allowing the rotating grinding disc 14 to contact the outside of the valve body casting, thus facilitating the deburring. When it is necessary to adjust the support frame 3... After positioning the valve body casting, the insertion rod 26 can be pulled out of the insertion hole 27. Then, the handle 25 can be rotated, causing the screw 21 to rotate. The screw 21 then drives the threaded seat 22 to move horizontally left and right, allowing the threaded seat 22 to drive the support frame and the valve body casting to move synchronously. This allows the position of the valve body casting to be adjusted, facilitating the grinding disc 14 to grind different positions of the valve body casting, thus improving the convenience of grinding. At the same time, the dust extraction fan 92 can be started, allowing the dust intake air to pass through the dust extraction hood 10 and the dust extraction pipe 94 to extract the iron filings generated during the grinding of the valve body casting. The extracted iron filings are then transported to the dust collection box 93 for storage, facilitating collection and preventing iron filings from scattering on the mounting platform 1. This eliminates the need for manual cleaning and improves the effectiveness of the device.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
