Description

Technical Field

[0001] This utility model belongs to the field of oil distribution plate technology, specifically relating to a handheld oil distribution plate grinding fixture. Background Technology

[0002] Currently, while power tools are available to grind the valve plate, they cannot replace manual grinding. The output power of a piston pump is largely affected by the fit between the cylinder block and the valve plate. Technicians can determine the fit by observing the contact points of the scratch marks. Furthermore, before reassembling the valve plate onto the piston pump, it needs to be ground to remove scratches and reduce its thickness to a certain extent. Then, it is reassembled and tested until the piston pump reaches the expected output power. Once the expected output power is achieved, the piston pump assembly is complete.

[0003] When grinding a single oil distribution plate, it is necessary to grind it manually. Manual grinding for a long time can easily cause fatigue, which reduces the grinding accuracy. Moreover, there is no special tool for holding the oil distribution plate in the existing tools. The operator can only hold the oil distribution plate by hand for grinding, which is not only easy to slip but also difficult to control the force and angle, which can easily lead to safety accidents and greatly reduce the efficiency of the work.

[0004] In traditional manual grinding methods, operators usually hold the oil distribution plate by hand, which is prone to slipping and shaking, resulting in uneven grinding and even damage to parts. In addition, traditional tools are difficult to adapt to oil distribution plates with different hole diameters and specifications, and changing parts is cumbersome and lacks versatility. Therefore, we propose a handheld oil distribution plate grinding fixture. Utility Model Content

[0023] Example 1

[0024] like Figures 1-4 As shown;

[0025] A handheld oil-dispensing disc grinding fixture includes a fixture body 1, a support plate 7, and a grinding disc 15. Both ends of the fixture body 1 are fixed with insertion rods 4, each with a threaded end 5. A rotating rod 2 is sleeved on the outside of the insertion rods 4. A linkage table 6 is connected to the bottom of the fixture body 1 via a bearing. Electric push rods 9 are installed on both sides of the linkage table 6. A positioning block 10 is connected to the drive end of the electric push rod 9. The support plate 7 is installed on the outside of the positioning block 10, and a positioning bolt 11 passes through the positioning block 10. A fixing rod 12 is fixed to the lower end of the rotating rod 2. A tension rod 13 is movably connected below the fixing rod 12. The grinding disc 15 is fixed below the tension rod 13, and a grinding plate 16 is fixed to the lower end of the grinding disc 15.

[0026] In this implementation plan: the support plate 7 is extended and retracted by the electric push rod 9 to adapt to oil distribution plates with different inner diameters. The anti-slip patch 8 enhances friction and prevents slippage. The support plate 7 can be quickly replaced to adapt to various specifications of oil distribution plates. The electric push rod 9 controls clamping and releasing, improving the efficiency of parts replacement.

[0027] In an optional embodiment, the rotating rod 2 has a thread inside that mates with the threaded end 5, and the rotating rod 2 is threadedly connected to the tooling body 1 via the plug rod 4.

[0028] In this implementation scheme, the force of the rotating handle 3 is reliably transmitted to the entire tooling body 1 through the threaded transmission engagement between the rotating rod 2 and the threaded end 5 at the end of the plug rod 4. The structure is simple, the transmission is stable, and slippage or disengagement between the rotating rod 2 and the tooling body 1 is avoided.

[0029] In an optional embodiment, a handle 3 is fixed on the rotating rod 2, and the linkage table 6 is connected to the tooling body 1 by a rolling bearing.

[0030] In this implementation plan: a dedicated handle 3 is fixedly installed on the rotating rod 2, which conforms to ergonomics and facilitates the operator's application of force and control. The linkage table 6 is connected to the tooling body 1 by a rolling bearing, which greatly reduces the frictional resistance when the tooling body 1 rotates, making the operation through the handle 3 more labor-saving, flexible and stable.

[0031] In an optional embodiment, the outer wall of the support plate 7 is provided with anti-slip patches 8.

[0032] In this implementation scheme: the anti-slip patch 8 can significantly increase the friction between the support plate 7 and the inner wall of the oil distribution plate, effectively preventing relative sliding or slippage during the grinding process.

[0033] In an optional embodiment, the support plate 7 is detachably connected to the positioning block 10 by positioning bolts 11.

[0034] In this implementation scheme: the detachable connection allows the tooling to quickly replace support plates 7 of different sizes or shapes, thereby adapting to oil distribution plates of various inner diameters, greatly enhancing the tooling's versatility and applicability, and making replacement operations simple and quick.

[0035] In an optional embodiment, the fixed rod 12 and the tension rod 13 are telescopically connected, and a positioning knob 14 is installed at the connection between the tension rod 13 and the fixed rod 12.

[0036] In this implementation scheme: the fixed rod 12 and the tension rod 13 adopt a telescopic structure and are locked by the positioning knob 14, realizing stepless adjustment of the grinding height. This allows the grinding disc 15 and the grinding plate 16 to accurately adapt to oil distribution discs of different thicknesses or different installation states, ensuring that the grinding plate 16 can always fit the grinding surface with the best pressure and contact area, greatly improving the grinding accuracy and processing quality.

[0037] Working principle:

[0038] Installation and adjustment: Install the support plate 7 onto the positioning block 10 using the positioning bolts 11. Select a suitable support plate 7 according to the inner diameter of the oil distribution plate. Then start the electric push rod 9 to push the positioning block 10 and the support plate 7 outward until the anti-slip patch 8 on the outer wall of the support plate 7 is in close contact with the inner wall of the oil distribution plate, thus achieving initial fixation and centering.

[0039] Adjust the height by loosening the positioning knob 14, adjusting the relative length of the tension rod 13 and the fixing rod 12, so that the grinding plate 16 is in contact with the oil distribution plate to be ground, and then tightening the positioning knob 14 to ensure the height is stable during the grinding process;

[0040] In the grinding operation, the operator holds the handle 3 and drives the entire tooling body 1 to rotate by rotating the rotating rod 2. The rotating rod 2 is connected to the tooling body 1 through the plug rod 4. The linkage table 6 is connected to the tooling body 1 through the bearing to ensure flexible rotation. The grinding disc 15 and the grinding plate 16 rotate with the tooling to achieve uniform grinding of the oil distribution plate surface.

[0041] After grinding, the electric push rod 9 retracts and the support plate 7 detaches from the inner wall of the oil distribution plate. The tooling can be easily removed, and the support plate 7 can be disassembled or the tension rod 13 can be adjusted for future use or replacement of parts.

[0042] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
