The color-changing valve is usually located in the robot's arm, close to the atomizer, and is integrated by multiple color-changing blocks, each of which can switch two colors. The color-changing valve group realizes the switching of paint colors by controlling the opening and closing of the microvalve. The microvalve is opened under the action of compressed air, allowing the paint to flow from one pipeline into the common channel, and then enter the gear pump through the voltage stabilizer, and finally atomized through the rotary cup under the action of high-voltage static electricity and shaping air and attached to the surface of the vehicle body. As spraying robots gradually replace manual spraying, and the types of color-changing valves are diverse, therefore, for the disassembly and assembly of some special color-changing valves such as SAMES color-changing valves and UP valves, ordinary valve disassembly tools such as wrenches, screwdrivers or pliers are used in the process of disassembly, because the valve disassembly tools cannot fully fit the valve, and the valve body 7 is mainly made of plastic, the above-mentioned valve disassembly tools are easy to cause damage to the valve body 7.

[0023] The following is combined with Figure 1-4 The embodiments of the present utility model are described in detail.

[0024] Example 1

[0025] The utility model relates to a valve dismantling tool for a color-changing valve, which is used for being sleeved on one end of the color-changing valve connected to an air pipe to separate the color-changing valve from a color-changing valve block, and the one end of the color-changing valve connected to the air pipe is in a stepped shape. The valve dismantling tool for the color-changing valve comprises a rod body 1, and the rod body 1 has a working end 11 and a screwing end 12, and the working end 11 and the screwing end 12 are respectively located at two ends of the rod body 1; along the length direction of the rod body 1, the working end 11 is sequentially provided with a first groove 2 and a second groove 2 from the outside to the inside, and the side walls of the first groove 2 and the second groove 3 are in a stepped shape, and the stepped side walls match the stepped shape of one end of the color-changing valve connected to the air pipe.

[0026] Specifically, Figure 1 As shown, the valve removal tool in the present application includes a rod body 1, and the shape of the rod body 1 can be a rectangular cylinder or a triangular cylinder or a main body of other shapes, preferably a cylinder. Figure 5 As shown, the color-changing valve in the present application includes a valve body 7, the left end of the valve body 7 is a valve connection end 71, which is connected to the color-changing valve block, and the right end of the valve body 7 is an air connection end 72, which is connected to the air pipe, and the air connection end 72 is stepped. The rod body 1 includes a working end 11 that matches the shape of the air connection end 72 of the valve body 7 and a screwing end 12 for screwing the rod body 1 to realize the disassembly of the valve body 7; wherein, in order to make the valve disassembly tool fit the color-changing valve, the working end 11 is configured to include a first groove 2 and a second groove 3 opened along the length direction of the rod body 1, and the side walls of the first groove 2 and the second groove 3 form a step-like shape that matches the air connection end 72 of the valve body 7, that is, the straight-line distance from the side wall of the first groove 2 to the center line of the rod body 1 is greater than the straight-line distance from the side wall of the second groove 3 to the center line of the rod body 1, so that the valve disassembly tool can be directly sleeved outside the air connection end 72 of the valve body 7, which not only protects the valve body 7, but also facilitates the disassembly of the valve body 7.

[0027] It should be noted that the shape of the first groove 2 and the second groove 3 can be circular or partially arc-shaped, that is, the inner walls on the two opposite sides are arc-shaped, and the rest are straight; or most of the inner walls are arc-shaped, and the rest are straight, etc., as long as the air connecting end 72 can be embedded in the first groove 2 and the second groove 3 and part or all of the outer wall of the color-changing valve matches the inner wall of the first groove 2 and the second groove 3. Of course, the size of the above two grooves can be designed according to actual needs, so that the valve removal tool can adapt to the air connecting end 72 of the color-changing valve of different sizes and shapes.

[0028] When the color-changing valve needs to be disassembled, the working end 11 is sleeved on the air-connecting end 72 of the color-changing valve, and then the screwing end 12 is screwed to remove or install the color-changing valve. During the screwing process, tools such as a wrench can be used for screwing, or manual screwing can be used. The screwing method can be selected according to the on-site conditions.

[0029] As a variation, an anti-slip pattern can be provided on the screwing end 12 to increase the friction when holding the valve removal tool and prevent slipping due to sweat or grease on the hand during use; a rotating handle can also be provided on the screwing end 12 to facilitate the user to rotate to loosen or tighten the color-changing valve. If the valve removal tool is operated using a tool such as a wrench, the screwing end 12 can be set to an outer hexagonal or inner hexagonal shape, and both can realize the screwing of the valve removal tool.

[0030] Example 2

[0031] This embodiment is an improvement on the embodiment 1, the difference being that the rod body 1 is cylindrical, the first groove 2 and the second groove 3 are opened along the center line of the axial direction of the rod body 1, the first groove 2 and the second groove 3 are both circular, and the diameter of the first groove 2 is greater than the diameter of the second groove 3.

[0032] Specifically, since the cylindrical rod body 1 can better disperse the pressure due to its symmetry, the rod body 1 is designed to be cylindrical with better bending resistance in the present application, that is, the first groove 2 and the second groove 3 are opened along the center line of the axial direction of the rod body 1, so that after being sleeved outside the air connecting end 72 of the color changing valve, the entire whole is more stable, and when the valve disassembly tool is screwed, the forces in all directions are balanced, which is not easy to damage the valve disassembly tool or the valve body 7.

[0033] Example 3

[0034] This embodiment is an improvement on the basis of Embodiment 2, the difference being that, on the inner wall of the first groove 2, a fixing column 4 for cooperating with the color-changing valve is provided in a direction parallel to the depth direction of the first groove 2, and the fixing columns 4 are at least two and are symmetrically provided on the inner wall of the first groove 2.

[0035] Specifically, in order to further fit the valve disassembly tool to the valve body 7 and ensure that the color-changing valve can be firmly fixed at a predetermined position when inserted into the first groove 2, it is convenient to disassemble the color-changing valve. Figure 1-3 and Figure 5 As shown, a fixing column 4 for cooperating with the groove 8 on the gas receiving end 72 is arranged on the inner wall of the first groove 2 in a direction parallel to the depth direction of the first groove 2. This symmetrical layout not only ensures the stability of the structure, but also makes the insertion and removal of the color changing valve easier.

[0036] There are at least two fixing columns 4 symmetrically arranged on the inner wall of the first groove 2. The number of the fixing columns 4 can also be adjusted accordingly according to the structure of the color-changing valve. For example, if there are four grooves on the color-changing valve, the number of the fixing columns 4 is also set to four.

[0037] Example 4

[0038] This embodiment is an improvement on the basis of the embodiment 3, the difference being that the fixing column 4 is cylindrical, and the center line of each fixing column 4 in the axial direction is parallel to the center line of the first groove 2 in the axial direction; in the radial direction of the fixing column 4, half of the fixing column 4 is embedded in the rod body 1, and the other half of the fixing column 4 is located in the first groove 2.

[0039] Specifically, in order to make the fixing column 4 fit better with the groove 8 on the gas connecting end 72, the fixing column 4 is set to be cylindrical, and all the fixing columns 4 are set in parallel. At the same time, the center line of the axial direction of each fixing column 4 is parallel to the center line of the axial direction of the first groove 2. In this way, when the valve removal tool is rotated, the axial directions of the fixing column 4 and the first groove 2 and even the entire rod body 1 are in a straight line, so that the entire valve removal tool is subjected to balanced force.

[0040] More specifically, Figure 3 As shown, the fixing column 4 is arranged inside the rod body 1, half of the fixing column 4 is embedded in the rod body 1, and the other half is located in the first groove 2, that is, the cylindrical fixing column 4 is cut along the axial direction and divided into two halves, one half is located in the rod body 1, and the other half is located in the first groove 2. In this way, when the fixing column 4 is subjected to a radial force within a certain range, for example, when the force is applied when the rod body 1 is screwed, a certain elastic deformation can occur, thereby playing a role of buffering and shock absorption, which not only improves the seismic performance of the structure, but also enables the rod body 1 to better protect the internal components from damage when it is impacted by external forces.

[0041] Example 5

[0042] This embodiment is an improvement on the embodiment 1, the difference being that, at the screwing end 12, a first screwing portion 5 and a second screwing portion 6 are sequentially arranged along the center line of the axial direction of the rod body 1, and the first screwing portion 5, the second screwing portion 6 and the rod body 1 form a stepped shape.

[0043] Specifically, Figure 4 As shown, the screwing end 12 includes a first screwing portion 5 and a second screwing portion 6 arranged in sequence along the center line of the axial direction of the rod body 1. The first screwing portion 5, the second screwing portion 6 and the rod body 1 form a step shape, which is equivalent to the first screwing portion 5, the second screwing portion 6 and the rod body 1 being on the same center line, and the entire valve removal tool is more stable. The first screwing portion 5 and the second screwing portion 6 can both be protruding from the rod body 1, or can both be grooves opened on the rod body 1, or the first screwing portion 5 can be a groove opened on the rod body 1, and the second screwing portion 6 can be a protrusion on the rod body 1; when it is a protruding part, a tool such as a wrench can be used to screw the protruding part; when it is a groove, a wrench can be inserted into the groove to screw it. When screwing the screwing end 12, only the first screwing portion 5 can be screwed, or only the second screwing portion 6 can be screwed. There are various screwing methods and strong adaptability.

[0044] Example 6

[0045] This embodiment is an improvement on the basis of the embodiment 5, and the difference lies in that, in the first screwing portion 5, a third groove 51 is provided along the center line of the axial direction of the rod body 1; the second screwing portion 6 is a boss formed by protruding outward along the bottom of the first screwing portion 5, and the projection of the boss along the axial direction of the rod body 1 is located within the projection of the rod body 1 along its axial direction.

[0046] Specifically, Figure 4 As shown, the first screwing portion 5 is a third groove 51 opened along the center line of the axial direction of the rod body 1, and the second screwing portion 6 is a boss formed by protruding outward along the bottom of the first screwing portion 5, and the projection of the boss along the axial direction of the rod body 1 is located within the projection of the rod body 1 along its axial direction. The third groove 51 can be circular or other shapes such as an inner hexagon. When screwing through the third groove 51, a tool such as a round wrench or an inner hexagon wrench is inserted into the third groove 51 and screwed. The boss can be circular or other shapes such as an outer hexagon, so that when the valve removal tool is screwed through the boss, a tool such as an outer hexagon wrench can be used to clamp the outer periphery of the boss for screwing.

[0047] Example 7

[0048] This embodiment is an improvement made on the basis of the embodiment 6, the difference being that the third groove 51 is in an inner hexagonal shape, and the boss is in an outer hexagonal shape.

[0049] Specifically, in order to more conveniently disassemble the color-changing valve, Figure 4 As shown, the third groove 51 is set to an inner hexagon and the boss is set to an outer hexagon. In this way, the color-changing valve can be disassembled using only an inner hexagon wrench matching the third groove 51, or only an outer hexagon wrench matching the boss.

[0050] Example 8

[0051] This embodiment is an improvement made on the basis of Embodiment 7, the difference being that the valve disassembly tool for the color-changing valve is made of aluminum alloy.

[0052] Specifically, since the valve body 7 of the color-changing valve is usually made of plastic, in order to avoid the color-changing valve being damaged by the valve removal tool during the disassembly of the color-changing valve, the valve removal tool in the present application is made of aluminum alloy. This is because, generally speaking, aluminum alloy is softer and has a lower hardness than many plastic materials. Therefore, under normal circumstances, combined with correct usage methods and appropriate tool design, it is possible to ensure that the plastic valve body 7 is intact.

[0053] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
