[0002] In the automotive electronic parts manufacturing industry, the residual burrs in the small holes of valve body parts have always been a difficult problem for major parts suppliers to deal with. Traditionally, special parts valve body cleaning equipment is used to remove the residual burrs in small holes. The main cleaning method is to clamp the valve body into a cleaning fixture and flush it through a four-axis device.

This causes many residual burrs to be flushed into the one-way dead end of the valve body and cannot be flushed out. In order to achieve synchronous linkage flushing of multiple surfaces, it is necessary to solve the problem of how to generate flushing pulse water flow during the flushing process.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] like Figures 1 to 5As shown, the utility model provides an adjustable pulse flushing device for flushing the small holes penetrating the inside of the valve body, which mainly includes a driving mechanism 2, a distribution mechanism 1 and an actuator 3, a total of three parts. Among them, the actuator 3 includes a valve body positioning seat 31 for positioning the valve body 300. The valve body positioning seat is provided with a plurality of oil circuit plates corresponding to each side of the valve body, and the valve body positioning seat 31 is provided with water channel holes 311 that are connected to the small holes penetrating the various sides of the valve body, that is, the oil circuit plates are provided with water channel holes corresponding to the small holes on the valve body surface, which can be connected by pipelines. When the high-pressure water source comes through the actuator, each high-pressure water source will flush the small holes penetrating the inside of the valve body along the water channel holes, and at the same time, the burrs flushed away will be flushed out of the product along the water channel holes, so as to achieve the purpose of cleaning the product.

[0033] The distribution mechanism is the core part of the adjustable pulse flushing device. The distribution mechanism 1 includes an oil circuit distribution seat 12 with a central inner hole 121 and a steering piston 13 rotatably connected to the central inner hole. The steering piston 13 is provided with a piston water inlet 132 and a piston water outlet 133 which are always in a connected state. The oil circuit distribution seat 12 is provided with a distribution seat water inlet 122 and a distribution seat water outlet 123 which are connected to the central inner hole 121. There are at least two distribution seat water outlets 123 distributed along the circumference of the oil circuit distribution seat. The distribution seat water inlet 122 is connected to a high-pressure water source, that is, the distribution seat water inlet 122 and the distribution seat water outlet 123 are connected through the central inner hole 121. The piston water inlet 132 is always connected to the distribution seat water inlet 122 during the rotation of the steering piston 13, so that the high-pressure water source is always connected to the distribution seat water inlet 122, the piston water inlet 132 and the piston water outlet 133.

[0034] In order to realize that the piston water outlet 133 is connected with one of the distribution seat water outlets 123 after the rotation direction. The piston water outlet 133 corresponds to the distribution seat water outlet 123 in height position. Every time the steering piston rotates a set angle, the piston water outlet 133 rotates a direction to connect with one of the distribution seat water outlets 123 on the oil circuit distribution seat, so that the high-pressure water source is output to the distribution seat water outlet 123 in different directions through the steering piston 13. In this way, the piston water outlet and the two adjacent distribution seat water outlets on the oil circuit distribution seat can be switched on and off, that is, the first distribution seat water outlet is disconnected, and the second distribution seat water outlet is connected, so that the high-pressure water source is output at the distribution seat water outlets in different directions. As the rotation speed of the steering piston increases, the pulse output of the high-pressure water source can be realized, and then the valve body is pulse-cleaned after passing through the water channel hole.

[0035] When the driving mechanism transmits power to the steering piston, the steering piston will rotate according to the set speed, so that the piston water outlet 133 is aligned with the corresponding distribution seat water outlet 123, and the distribution seat water outlets in different positions can be switched accurately and in real time to achieve the flushing water supply of the required pipeline.

[0036] Specifically, a guide hole 131 extending along the central axis in the up-down direction is provided at the center of the steering piston 13, and the piston water inlet 132 and the piston water outlet 133 both extend along the radial direction of the piston, and the guide hole 131 communicates with the piston water inlet 132 and the piston water outlet 133. The lower end of the guide hole passes through the lower end surface of the steering piston and is equipped with a sealing plug, and the upper end of the guide hole is communicated with the piston water outlet, which is located on the upper side of the piston water inlet, extends radially and vertically penetrates the guide hole.

[0037] In order to ensure that the high-pressure water source is always connected to the piston water inlet, the steering piston 13 is circumferentially provided with an annular flow channel groove 134 connected to the piston water inlet 132, and the distribution seat water inlet 122 is fixed at the radial outer side of the steering piston and is connected to the annular flow channel groove. Therefore, during the rotation of the steering piston, the distribution seat water inlet 122 is always connected to the annular flow channel groove.

[0038] Furthermore, the distribution mechanism 1 also includes bearings 135 installed at the shaft shoulders of both ends of the steering piston 13. For example, deep groove ball bearings. The deep groove ball bearings are installed after the steering piston is installed and installed together into the central inner hole. The steering piston is rolled by the bearings to ensure that the steering piston does not wear unevenly when rotating and reduce abnormal rotation noise.

[0039] In order to prevent water leakage, the distribution mechanism 1 further includes O-rings 136 installed in the outer cylindrical sealing grooves at both ends of the steering piston 13. Of course, other sealing rings can also be used. In addition, the piston water inlet 132 and the piston water outlet 133 are both located between the upper and lower O-rings 136. Therefore, during the rotation of the piston, the O-rings are used to seal to ensure that there is no leakage during the transmission of high-pressure water.

[0040] Furthermore, the oil circuit distribution seat 12 is installed on the distributor bottom plate 11, and the lower end of the central inner hole is provided with a positioning ring groove, and a bearing pad ring 137 is installed in the positioning ring groove. The upper end of the bearing pad ring presses the lower end surface of the bearing (i.e., the bearing installed at the position of the shaft shoulder at the lower end of the steering piston), and the lower end fits the distributor bottom plate. In this way, the shaft shoulder positions the upper end of the bearing, and the bearing pad ring fixes the lower end of the bearing to ensure that the bearing does not fall off when the steering piston rotates at high speed; at the same time, since there is a gap between the lower end of the steering piston and the distributor bottom plate, the bearing pad ring also positions the lower end of the steering piston to ensure the axial position of the steering piston.

[0041] In this embodiment, the oil circuit distribution seat 12 is a regular hexagonal structure, so that six distribution surfaces are formed in the circumferential direction, and the central inner hole 121 is located in the middle of the hexagon and is installed in conjunction with the steering piston 13. In addition, a distribution seat water outlet 123 is provided on each distribution surface for connecting and outputting with the actuator. And the two circumferentially adjacent distribution seat water outlets 123 are spaced 60 degrees apart, so that every time the steering piston rotates 60 degrees, a distribution seat water outlet 123 is switched for output. In addition, a distribution seat water inlet 122 is provided on at least one of the distribution surfaces, for example, two of the distribution surfaces are each provided with a distribution seat water inlet, and the two distribution seat water inlets are located on two distribution surfaces of the oil circuit distribution seat that are spaced at least one distribution surface in the circumferential direction, such as the first and fourth distribution surfaces. The two distribution seat water inlets can be connected to two high-pressure water sources at the same time to ensure stable output water pressure. Of course, the oil circuit distribution seat 12 can also be a regular quadrilateral structure, or a regular octagonal structure, etc.

[0042] The driving mechanism 2 is used to drive the steering piston 13 to rotate, and the driving mechanism 2 includes a driving motor 21, a reducer 22, a coupling 24, and a reducer mounting seat 23. The driving motor can be a servo motor, which is controlled by a pulse controller to achieve output of controllable speed. The pulse controller controls the driving motor to output at a set speed so that the steering piston rotates according to the set speed, thereby correspondingly controlling the pulse frequency of the pulse output of the distribution seat outlet in different directions of the high-pressure water source. Through program setting, the effect of pulse flushing of the valve body holes on two or more sides can be achieved. After repeated flushing, the burrs of the small holes inside the valve body can be easily flushed down, achieving the required valve body cleanliness requirements and meeting the needs of subsequent assembly.

[0043] In addition, the reducer mounting seat 23 is mounted on the oil distribution seat 12, and the reducer 22 is mounted on the reducer mounting seat 23. The input end of the reducer is connected to the output shaft of the drive motor 21, and the output end of the reducer is connected to the steering piston 13 through the coupling 24. Specifically, the servo motor output shaft and the reducer input end are keyed to transmit and convey the rotation speed, and the corresponding output torque is increased by the reducer to prevent the drive mechanism from being stuck due to insufficient driving torque. The reducer output end and the coupling are also connected through a keyway to convey the corresponding torque. The reducer end face corresponds to the reducer mounting seat mounting hole through the screw hole, and the fixing screws are connected to ensure that the drive mechanism is firmly installed.

[0044] In addition, threaded mounting holes are provided on the distributor base plate 11, and through holes are provided corresponding to the threaded mounting holes in the reducer mounting seat and the oil circuit distribution seat, which are connected with mounting screws, and the mounting screws are threadedly connected to the threaded mounting holes to ensure that the entire mechanism is more stable during operation.

[0045] like Figure 4 and Figure 5As shown, the actuator 3 also includes a side pressure block 32, a quick clamp 33, a quick clamp base 34 and a valve body positioning seat bottom plate 35. The valve body positioning seat 31 is installed on the valve body positioning seat bottom plate 35, and the quick clamp base 34 is arranged on the side of the valve body positioning seat. The quick clamp base 34 is installed with a quick clamp 33 for quickly fixing the valve body on the valve body positioning seat. The specific structure of the quick clamp can directly adopt the existing technology to quickly install and fix the valve body to ensure that the valve body will not shake when flushing the product. A valve body positioning groove is provided on the valve body positioning seat 31. Taking the positioning of the rectangular valve body as an example, the valve body positioning groove is a U-shaped structure and the opening is facing the horizontal side. Three oil circuit plates are arranged corresponding to the three valve body surfaces of the rectangular valve body, and each oil circuit plate has a water channel hole. The side pressure block 32 is arranged on the side of the valve body positioning seat. The side pressure block can be connected to the quick clamp, so that the valve body can be pressed at the opening position of the valve body positioning groove. Corresponding to the fourth valve body surface, the side pressure block 32 is also provided with water channel holes, corresponding to the small holes on the fourth valve body surface. When the high-pressure water source is connected, the small holes on the valve body surface corresponding to the valve body will be flushed through the water channel holes on the side pressure block. The bottom of the valve body positioning seat bottom plate 35 is provided with a threaded mounting hole, which cooperates with the mounting screw to fix the actuator in a specified position to ensure the stability of the mechanism when the high-pressure water passes through.

[0046] The flushing device of the utility model uses a servo motor to drive a rotating piston to realize the pulse flushing function of high-pressure water flow, and the pulse frequency can be adjusted according to the motor speed. It abandons the original traditional single-hole single-sided flushing method, and the flushing efficiency is greatly improved compared with before. The volume structure of the flushing device is also more compact, which is more convenient for the promotion and use of subsequent non-standard automated production lines.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
