Description

Technical Field

[0001] The invention relates to the technical field of valve core processing, in particular to a deburring device for processing a flow control valve core. Background Art

[0002] The flow control valve, also known as the 400X flow control valve, is a multifunctional valve that uses a high-precision pilot control method to control flow. During the production process of the flow control valve spool, the inner wall of the spool contains a large number of burrs that need to be removed. There are many methods for deburring, and abrasive flow polishing is an excellent deburring method.

[0003] The valve core in the existing technology is mainly composed of components such as a valve stem, a valve head and a valve seat. Generally, abrasive flow polishing is used to deburr the valve core, and the valve seat is also deburred. During processing, the abrasive flow is directly injected into the inside of the valve seat to achieve the corresponding polishing effect. Although this method will not affect the valve seat, if the valve seat is deburred only by flow, some abrasive flow will inevitably remain in the prefabricated groove of the valve seat. If these residual abrasive flows are not cleaned, the subsequent processing effect will be greatly affected.

[0004] Therefore, the existing demand is not met, and we propose a deburring device for processing the valve core of a flow control valve. Summary of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] For example 1, please refer to Figures 1-11 A deburring device for processing a flow control valve core comprises a processing table 1, a mounting plate 102 is mounted on the processing table 1, a material storage box 103 is provided on the mounting plate 102, and a material storage box 103 is provided on the mounting plate 102. Figure 2 It can be seen that a driving motor is installed on the mounting plate 102, and a fixed connection is formed between the output end of the driving motor and the transmission screw, and the material storage box 103 is connected to the transmission screw through a connecting piece. Therefore, when the user needs to deburr the valve core, the user only needs to start the driving motor, and the material storage box 103 will move down on the transmission screw and gradually approach the storage piece 101.

[0036] It should be noted that a positioning piece for positioning and clamping the valve core is provided on the storage piece 101. The positioning piece is a positioning component commonly used by people in this field. Users can adjust it according to actual conditions and their own needs. It will not be elaborated here. That is to say, before the storage box 103 moves downward, the user only needs to use the positioning piece to install the valve core to be deburred on the storage piece 101.

[0037] Since a storage cavity for holding the abrasive flow is provided inside the storage box 103, when the storage box 103 moves down to the position of the placement piece 101 and is completely in contact with the table surface of the processing table 1, the user can control the drive motor to stop rotating. Since a pressing piece 108 is also provided inside the storage box 103, the pressing piece 108 is an existing technology for squeezing the abrasive flow by people in this field. The user can adjust it according to actual conditions and will not go into details here. That is to say, when the storage box 103 is completely in contact with the placement piece 101, the user can control the pressing piece 108 to discharge the abrasive flow temporarily stored in the storage cavity out of the storage box 103 and into the valve core prefabricated groove provided on the placement piece 101. In this way, the burrs inside the valve core can be effectively removed through the flow of the abrasive flow.

[0038] Example 2: This example is an improvement based on Example 1. For details, please refer to Figures 1-11 When the driving components are the liquid storage capsule 205, the liquid storage tank 104 and the liquid injection tube 105, refer to Figure 4 It can be seen that the pressing member 108 is also connected to the first connecting rod 106, and the other end of the first connecting rod 106 is fixedly connected to the corresponding first extrusion plate 112, and the first extrusion plate 112 is slidably set inside the liquid storage tank 104. It should be noted that a certain amount of hydraulic oil is set inside each liquid storage tank 104. Therefore, when the pressing member 108 squeezes the abrasive flow, the first connecting rod 106 will also synchronously drive the first extrusion plate 112 to squeeze the hydraulic oil set inside the liquid storage tank 104.

[0039] See Figure 5 It can be seen that a connecting pipe 115 is fixedly installed on the liquid storage tank 104, and the connecting pipe 115 is connected to the liquid storage tank 104, and a first extrusion member 119 is slidably provided inside the connecting pipe 115, and a second spring 116 is provided between the first extrusion member 119 and the connecting pipe 115. It should be noted that the second spring 116 is always in a stretched state, and a limit block 117 is also provided inside the connecting pipe 115, that is, when the first extrusion member 119 is subjected to the return elastic force of the second spring 116 to Figure 6 When the middle liquid outlet 118 moves in the direction of the first extrusion member 119 , the first extrusion member 119 will be restricted by the limiting block 117 , thereby allowing the first extrusion member 119 to complete the blocking of the liquid outlet 118 , and this blocking is continuous.

[0040] Therefore, even if the pressing member 108 synchronously drives the first connecting rod 106 to move and drives the first extrusion plate 112 to squeeze the hydraulic oil, the hydraulic oil will not be discharged from the liquid storage tank 104. However, as the first connecting rod 106 continues to move, the pressure inside the liquid storage tank 104 will gradually increase. In order to prevent the first connecting rod 106 from being unable to move, a first spring 114 is provided at the bottom of the liquid storage tank 104, and a supporting plate 113 is connected to the first spring 114. That is to say, even if the hydraulic oil cannot be discharged from the liquid storage tank 104, the hydraulic oil can also squeeze the supporting plate 113, so that the first connecting rod 106 continues to drive the first extrusion plate 112 to move downward.

[0041] When the second extrusion member 125 provided on the first extrusion plate 112 contacts the first extrusion member 119 provided inside the connecting pipe 115, Figure 6 It can be seen that the first extrusion member 119 is provided with an extrusion slope, so the first extrusion member 119 will be squeezed by the second extrusion member 125, and then Figure 6The left shift in the process, it should be noted that a sliding plate is fixedly sleeved on the first extrusion member 119, and a through groove is provided on the sliding plate. The hydraulic oil can effectively pass through the sliding plate through the opening of the through groove. The setting of the sliding plate allows the first extrusion member 119 to move, and the first extrusion member 119 can only move in the corresponding horizontal direction after it moves, and will not deviate left and right during the movement, so as to prevent the first extrusion member 119 from being able to effectively complete the blocking of the liquid outlet 118 after it is reset. When the first extrusion member 119 completes the movement, the hydraulic oil will be discharged from the gap between the blocking end of the first extrusion member 119 and the connecting pipe 115, and injected into the liquid injection pipe 105 through the connecting hose. It should be noted that at this time, the abrasive flow arranged inside the storage box 103 has also completed the deburring effect on the valve core.

[0042] At the same time, when the first connecting rod 106 is subsequently reset, the first extrusion plate 112 connected to the first connecting rod 106 will also be reset synchronously, and the reset of the first extrusion plate 112 will generate a certain degree of negative pressure inside the liquid storage tank 104. Through this negative pressure, not only can the hydraulic oil discharged from the liquid storage tank 104 be returned to the inside of the liquid storage tank 104, but this negative pressure will also form a certain suction force on the blocking end of the first extrusion member 119, so that the second extrusion member 125 can release the pressure on the first extrusion member 119. 9, the first extrusion member 119 still does not reset, that is, before the first connecting rod 106 has not recovered all the hydraulic oil into the liquid storage tank 104, the first extrusion member 119 will never block the liquid outlet 118. When the hydraulic oil is completely recovered into the liquid storage tank 104, the negative pressure inside the liquid storage tank 104 will be released. At this time, the first extrusion member 119 can be reset accordingly through the reset elastic force of the second spring 116, so as to complete the blocking effect on the liquid outlet 118 again.

[0043] See Figure 7 It can be seen that the other end of the injection tube 105 is slidably set inside the connecting groove 107, and the other end of the connecting groove 107 is connected to the liquid storage bag 205 set inside the mounting sleeve 201 through the connecting pipe 204, that is, when the hydraulic oil inside the liquid storage tank 104 enters the injection tube 105, it will eventually be injected into the liquid storage bag 205.

[0044] Since the upper end of the liquid storage capsule 205 is fixedly connected to the lower end of the movable slide rod 207, it should be noted that the liquid storage capsule 205 is a corrugated liquid capsule. Through this setting, enough hydraulic oil can be stored inside the liquid storage capsule 205 to drive the movable slide rod 207 to move relatively long, and the movable slide rod 207 is slidably set inside the mounting sleeve 201. Therefore, as the liquid storage capsule 205 gradually expands, the movable slide rod 207 will slide upward inside the mounting sleeve 201.

[0045] Through the above arrangement, the movable slide rod 207 can be moved, and the movement of the movable slide rod 207 will also drive the cleaning disk 202 to complete the cleaning effect of the valve prefabricated groove and the object placement part 101.

[0046] Example 3: This example is an improvement based on Example 1. For details, please refer to Figures 1-11 , when the driving component is the driving cylinder 215, refer to Figure 3 It can be seen that since the output end of the driving cylinder 215 is directly fixedly connected to the bottom surface of the movable slide 207, when the storage box 103 completes the deburring effect on the valve core, the user can directly start the driving cylinder 215, so that the driving cylinder 215 drives the movable slide 207 to move upward directly. When the movable slide 207 moves upward, it will also drive the cleaning disk 202 to complete the cleaning effect of the valve prefabricated groove and the storage part 101.

[0047] Example 4: This example aims to solve the problem that in the prior art, when deburring the valve only by flow, some abrasive flow will inevitably remain in the valve prefabricated groove and the interior of the object holder 101. For details, please refer to Figures 1-11 The cleaning assembly 2 is composed of a mounting sleeve 201, a cleaning disc 202 and a movable slide rod 207. On the one hand, refer to Figure 7 It can be seen that a cleaning disc 202 is connected to the top of the movable slide bar 207, and the cleaning disc 202 is arranged directly below the object placement part 101. Therefore, when the movable slide bar 207 slides upward, the cleaning disc 202 will enter the through groove opened in the object placement part 101. Since the diameter of the cleaning disc 202 is slightly smaller than the diameter of the through groove opened in the object placement part 101, as the cleaning disc 202 moves upward, the abrasive flow remaining in the through groove of the object placement part 101 will be squeezed by the cleaning disc 202 and then discharged out of the object placement part 101 through the gap between the cleaning disc 202 and the through groove. This arrangement also effectively cleans the residual abrasive flow inside the object placement part 101, so that when the valve core is deburred next time, the interior of the object placement part 101 can be kept in a relatively clean state to prevent excessive residual abrasive flow inside the object placement part 101 from causing the subsequent abrasive flow to be unable to flow effectively, thereby affecting the deburring effect of the valve core.

[0048] At the same time, when the cleaning disk 202 moves to the inside of the prefabricated through groove of the valve core, since the diameter of the prefabricated through groove of the valve core is still slightly larger than the diameter of the cleaning disk 202, the abrasive flow remaining inside the valve core can also flow again through the gap between the two through the above-mentioned extrusion method, so that the residual abrasive flow can be used to further perform secondary grinding on the prefabricated through groove of the valve core, thereby improving the deburring efficiency of the prefabricated groove of the valve core to a certain extent.

[0049] See also Figure 7 It can be seen that one end of the second connecting rod 203 is connected to the movable slide rod 207, and the other end of the second connecting rod 203 is set inside the spiral groove 124 opened in the storage part 101 through the ball sliding. Therefore, when the movable slide rod 207 slides upward, the second connecting rod 203 will also move upward synchronously, and through the sliding between the ball and the liquid storage tank 104, it will also drive the storage part 101 set on the processing table 1 to rotate.

[0050] When the placement member 101 rotates, the abrasive flow remaining in the through groove of the placement member 101 can also be subjected to a certain degree of centrifugal force, so that the abrasive flow remaining in the through groove of the placement member 101 can be better cleaned and removed in conjunction with the movement of the cleaning disk 202. At the same time, the placement member 101 will also drive the valve core to rotate during the rotation process, thereby causing a certain amount of obstruction in the abrasive flow between the cleaning disk 202 and the prefabricated groove of the valve core, and causing the abrasive flow to generate a certain amount of torsional friction in the prefabricated groove of the valve core. In this way, the grinding effect on the inner wall of the prefabricated groove of the valve core is further improved.

[0051] See Figure 7 It can be seen that one end of the third connecting rod 206 is also provided inside the movable slide rod 207, and the other end of the third connecting rod 206 is slidably provided inside the limiting slide groove 123 provided on the inner wall of the processing table 1, see Figure 8 It can be seen that the limiting slide 123 is composed of a first moving position 1231 and a second moving position 1232, the first moving position 1231 and the second moving position 1232 are connected, and a part of the first moving position 1231 and the entire second moving position 1232 are provided with a limiting protrusion 1233. Therefore, when the moving slide 207 moves, the third connecting rod 206 provided inside the moving slide 207 will slide inside the first moving position 1231. When the third connecting rod 206 slides onto the limiting protrusion 1233, the third connecting rod 206 will be squeezed by the limiting protrusion 1233, so that Figure 9 Shift left in .

[0052] See Figure 10 It can be seen that the other end of the third connecting rod 206 is slidably connected to the third extrusion member 214, and the third extrusion member 214 is slidably arranged inside the movable slide rod 207. Figure 9 After the left shift in the third extrusion member 214 will also be synchronously Figure 10 Since both the third extrusion member 214 and the fourth connecting rod 212 are provided with an extrusion slope, the extrusion of the fourth connecting rod 212 by the third extrusion member 214 will also drive the fourth connecting rod 212 to move upward.

[0053] See Figure 11 It can be seen that the other end of the fourth connecting rod 212 is fixedly connected to the second extrusion plate 211, and the second extrusion plate 211 is arranged inside the cleaning disk 202. At the same time, since an airbag 209 is also provided inside the cleaning disk 202, and a wear-resistant contact piece 210 is provided on the outer surface of the airbag 209, when the fourth connecting rod 212 moves up, the second extrusion plate 211 will synchronously squeeze the airbag 209. When the airbag 209 is squeezed, the airbag 209 will expand accordingly, so that the contact piece 210 provided on the outer surface of the airbag 209 gradually extends out of the contact piece 210 and finally contacts the inner wall of the valve core prefabricated groove. It should be noted that at this time, the third connecting rod 206 has also moved to the connection between the first moving position 1231 and the upper end of the second moving position 1232, and enters the second moving position 1232.

[0054] It should be noted that the third link 206 is slidably arranged inside the third extrusion member 214. Therefore, even if the third link 206 slides from the first moving position 1231 into the second moving position 1232, the third link 206 will only slide on the third extrusion member 214 and will not affect the extrusion of the fourth link 212 by the third extrusion member 214. Moreover, since the limiting protrusion 1233 is provided inside the entire second moving position 1232, when the sliding rod 207 is reset and drives the third link 206 to reset, the third link 206 will still drive the third extrusion member 214 to press the fourth link 212. That is to say, when the sliding rod 207 is moved to reset and the cleaning disk 202 is driven to reset, the airbag 209 arranged inside the cleaning disk 202 is still in a squeezed state, that is, during the resetting process of the cleaning disk 202, the contact piece 210 connected to the airbag 209 will produce a certain degree of friction on the valve core prefabricated groove. It should be noted that the contact piece 210 is made of an elastic material, which can also be expanded into a ring. Through this arrangement, the cleaning disk 202 can use the contact piece 210 to polish the inside of the valve again during the resetting process, thereby further improving the efficiency of deburring the valve core.

[0055] And because the cleaning disk 202 will pass through the through groove opened in the object placement part 101 again during the resetting process, the contact part 210 connected by the inflated airbag 209 will also scrape the inner wall of the through groove opened in the object placement part 101 to a certain extent, thereby further improving the cleaning degree of the abrasive flow inside the object placement part 101.

[0056] When the third link 206 is pushed back into the first moving position 1231 again, the third link 206 will be released from the connection between the first moving position 1231 and the lower end of the second moving position 1232, and the first moving position 1231 here does not have a limiting protrusion 1233. Therefore, when the third link 206 slides into the first moving position 1231 again, the squeezing of the third link 206 will be released, and since a fourth spring 213 is provided between the fourth link 212 and the moving slide 207, when the squeezing of the third link 206 is released and the third squeezing member 214 is reset, the fourth link 212 will also be reset accordingly by the reset elastic force of the fourth spring 213, that is, the third squeezing member 214, the fourth link 212 and the airbag 209 will all be reset, so that the next time the moving slide 207 moves up, the above-mentioned movement effect can still be achieved.

[0057] It should be noted that the first and second moving positions 1231 and 1232 are connected by a first limiting flap 1234 and a second limiting flap 1235, respectively. Both the first limiting flap 1234 and the second limiting flap 1235 are rotatable, with the first limiting flap 1234 only rotating toward the second moving position 1232, and the second limiting flap 1235 only rotating toward the first moving position 1231. This arrangement prevents the third connecting rod 206 from returning to its original path during movement, thereby affecting the squeezing effect of the third extruding member 214 on the fourth connecting rod 212. It should also be noted that a user may also install a torsion spring at the rotatable connection between the first and second limiting flaps 1234 and 1235. This torsion spring arrangement allows the first and second limiting flaps 1234 and 1235 to instantly return to their original position after rotation, thereby limiting the movement trajectory of the third connecting rod 206 the next time the third connecting rod 206 moves.

[0058] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
