[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0027] Example 1:
[0028] like Figure 1 As shown, a cleaning fixture with an automatic extension function includes a base 1, a support block 2, a mounting baffle 3, and a telescopic cylinder 4. The support block 2 is connected to the upper part of the base 1. A through hole 2.1 is horizontally opened in the upper part of the support block 2.1. The telescopic cylinder 4 is sleeved in the through hole 2.1. The mounting baffle 3 is sleeved on the left side of the telescopic cylinder 4. The mounting baffle 3 is connected to the left side of the support block 2. A water flow cavity 1.1 is horizontally opened in the left part of the base 1. A water flow cavity 2.2 is opened in the lower part of the support block 2. A water flow cavity 4.1 is opened in the right part of the telescopic cylinder 4. The water flow cavity 1.1, the water flow cavity 2.1, the through hole 2.1, and the water flow cavity 4.1 are interconnected.
[0029] Specifically, when cleaning the workpiece is required, the part to be cleaned 7 is fixed on the base 1, and then the entire cleaning fixture is installed into the cleaning tank to fix the position of the part to be cleaned 7 for easy cleaning. By connecting the cleaning fluid nozzle to the inlet of the water flow chamber 1.1 of the cleaning fixture, during cleaning, the cleaning fluid enters the cavity between the support block 2 and the left side of the telescopic cylinder 4, and the inner cavity of the telescopic cylinder 4, respectively, through the water flow chamber 1.1 and the water flow chamber 2.1. The cleaning fluid forms a certain pressure in the cavity between the support block 2 and the left side of the telescopic cylinder 4, pushing the telescopic cylinder 4 to the right, so that the right side of the telescopic cylinder 4 extends into the hole of the part to be cleaned, until the telescopic cylinder 4 is blocked by the baffle 3. The cleaning fluid enters the hole of the part 7 to be cleaned through the inner cavity of the telescopic cylinder 4 to clean the inner hole of the part. During the cleaning process, the cleaning fluid maintains a certain pressure, and the cleaning fluid also maintains a certain pressure in the cavity between the support block 2 and the left side of the telescopic cylinder 4. This keeps the telescopic cylinder 4 in the extended position, preventing it from being pushed back by the turbulent flow of the cleaning fluid and detaching from the channel of the part being cleaned, thus avoiding the situation where the cleaning fluid cannot fully clean the inner hole of the part 7. After cleaning, the cleaning fixture is removed from the cleaning tank, and the telescopic cylinder 4 is pulled to the left to be pulled out from the part 7, thus removing the part 7 and completing the cleaning process. The automatic cleaning of the part 7 is achieved using water pressure, resulting in excellent cleaning effect.
[0030] Example 2:
[0031] In the embodiment 1, the water flow cavity two 2.2 comprises a main cavity one 2.21 and a sub-cavity one 2.22, the main cavity one 2.21 is vertically arranged, the lower part of the main cavity one 2.21 is communicated with the water flow cavity one 1.1; the middle part of the main cavity one 2.21 is communicated with the cavity between the left part of the telescopic cylinder 4 and the support block 2 through the sub-cavity one 2.22; the upper part of the main cavity one 2.21 is communicated with the water flow cavity three 4.1.
[0032] Specifically, the cleaning liquid in the water flow cavity one 1.1 is introduced to the water flow cavity three 4.1 through the main cavity one 2.21; the cleaning liquid in the water flow cavity one 1.1 is introduced to the cavity between the left part of the telescopic cylinder 4 and the support block 2 through the sub-cavity one 2.22, which is simple in structure.
[0033] Preferably, the left part of the telescopic cylinder 4 is in a stepped shape, and the outer diameter of the stepped shape increases from outside to inside.
[0034] Specifically, the stepped shape with the outer diameter increasing from outside to inside can form a cavity between the telescopic cylinder 4, the mounting baffle 3 and the support block 2 after the telescopic cylinder 4 is pulled to the left to a position where it cannot move due to the mounting baffle 3, so that the cleaning liquid in the sub-cavity one 2.22 enters and forms a pressure cleaning liquid to push the telescopic cylinder 4 to move to the right, which is simple in structure.
[0035] Preferably, the water flow cavity three 4.1 is upwardly formed along the central axis of the right part of the telescopic cylinder 4, the telescopic cylinder 4 at the left part of the water flow cavity three 4.1 is vertically formed with a water flow cavity four 4.2, and the main cavity one 2.21, the water flow cavity four 4.2 and the water flow cavity three 4.1 are communicated.
[0036] Specifically, the water flow cavity three 4.1 is upwardly formed along the central axis of the right part of the telescopic cylinder 4, which is used to change the water flow direction of the cleaning liquid so that it enters the parts to be cleaned.
[0037] Preferably, the water flow cavity four 4.2 is in a two-layer stepped shape, and the outer diameter of the two-layer stepped shape increases from inside to outside.
[0038] Specifically, the stepped water flow cavity four 4.2 with the outer diameter increasing from inside to outside, the cleaning liquid enters the water flow cavity three 4.1 from the cavity with a large outer diameter to the cavity with a small outer diameter, which can improve the pressure of the cleaning liquid entering the water flow cavity three 4.1.
[0039] Preferably, the outer diameter of the main cavity one 2.21 < the maximum outer diameter of the water flow cavity four 4.2 < the distance between the main cavity one 2.21 and the outer side of the support block 2.
[0040] Specifically, the water flow cavity four 4.2 ensures that the cleaning liquid in the main cavity one 2.21 can still flow into the water flow cavity three 4.1 through the water flow cavity four 4.2 after the telescopic cylinder 4 moves right to the limit position of the mounting baffle 3, and then flows into the parts to be cleaned, and does not flow out from the water flow cavity four 4.2 to the outside of the telescopic cylinder 4 and the support block 2.
[0041] Preferably, the through hole 2.1, the main cavity one 2.21 and the sub-cavity one 2.22 are all in cylindrical shape.
[0042] Specifically, the cylindrical structure is simple and does not easily cause the cleaning liquid to deposit on the cavity wall.
[0043] Preferably, the left end of the telescopic cylinder 4 penetrates out of the mounting baffle 3, and the left end of the telescopic cylinder 4 is provided with a handle 6 connected thereto.
[0044] Specifically, when the telescopic cylinder 4 moves right, the handle 6 is clamped on the left side of the mounting baffle 3 to prevent the telescopic cylinder 4 from continuing to move right, thereby playing a limiting role.
[0045] Preferably, the handle 6 is in the shape of a circular truncated cone, the left end of the telescopic cylinder 4 is horizontally sleeved in the inside of the circular truncated cone, and the outer diameter of the circular truncated cone increases from inside to outside.
[0046] Specifically, the handle 6 in this shape has a simple structure and is convenient for limiting and pulling left.
[0047] Preferably, the right end of the telescopic cylinder 4 is provided with a collision stop ring 5 connected thereto.
[0048] Specifically, the collision stop ring 5 avoids damaging the parts to be cleaned when the telescopic cylinder 4 is inserted into the parts to be cleaned.
[0049] The working principle of the utility model is as follows:
[0050] When the workpiece needs to be cleaned, the parts to be cleaned are fixed on the base 1, then the whole cleaning tool is loaded into the cleaning box, and the cleaning liquid nozzle is docked at the inlet of the water flow cavity one 1.1 of the cleaning tool. Figure 2As shown, the cleaning liquid will enter the cleaning tool from the inlet of the cleaning liquid flow cavity 1.1 at a certain pressure, and flow along the hole in the cleaning tool. When the cleaning liquid flows into the support block 2, part of the cleaning liquid enters the cavity between the support block 2 and the left part of the telescopic cylinder 4 through the sub-cavity 2.22, and the cleaning liquid forms a certain pressure in the cavity between the support block 2 and the left part of the telescopic cylinder 4, which pushes the telescopic cylinder 4 to move rightwards, so that the right part of the telescopic cylinder 4 extends into the hole of the part to be cleaned, until the handle 6 is blocked by the mounting baffle 3; the other part of the cleaning liquid enters the water flow cavity three 4.1 through the main cavity 2.21 and the water flow cavity four 4.2, and the cleaning liquid changes direction in the water flow cavity three 4.1 and flows rightwards, and then flows into the hole and the cavity of the part to be cleaned, so as to clean the hole and the cavity of the part. During the cleaning process, the cleaning liquid maintains a certain pressure, and the cleaning liquid in the cavity between the support block 2 and the left part of the telescopic cylinder 4 also maintains a certain pressure, so that the telescopic cylinder 4 is kept in the extended position and cannot be pushed back by the turbulent flow of the cleaning liquid, and thus the cleaning liquid cannot fully clean the hole of the part to be cleaned. After the cleaning is completed, the cleaning tool is taken out of the cleaning box, the handle 6 is pulled leftwards, and the part to be cleaned is pulled out of the hole, and the part to be cleaned is removed, and the cleaning is completed.
[0051] The utility model can fully clean the hole and the cavity of the part to be cleaned, achieve the expected cleaning effect, and has good cleaning effect.
