Description

Technical Field

[0001] This invention relates to the field of cleaning equipment, and more particularly to a cleaning device for the internal cavity of a diesel engine cylinder block. Background Technology

[0002] In the field of diesel engine cylinder block machining, internal cavity cleaning is a crucial step in ensuring product performance. Current cleaning devices generally suffer from poor adaptability; their fixed clamping structures are incompatible with the shaft hole dimensions of different cylinder block models, requiring frequent fixture changes, resulting in complex and inefficient operations. Furthermore, the fixed cleaning path leads to dead zones in complex areas such as the corners and shaft holes, especially for irregularly shaped cavities, where the high-pressure water jet coverage is limited, resulting in incomplete cleaning. In addition, existing equipment often separates the clamping and cleaning processes, requiring additional treatment of the shaft hole area, leading to redundant processes. Moreover, high-pressure cleaning can easily cause secondary contamination or damage to the internal cavity due to water jet impact and splashing of particulate impurities. These problems make it difficult for existing devices to meet the high-precision machining requirements of diesel engine cylinder blocks in terms of versatility, cleaning efficiency, and safety. Therefore, we propose an internal cavity cleaning device for diesel engine cylinder block machining to solve the aforementioned problems. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention overcomes the limitations of traditional cleaning equipment in terms of poor compatibility with cylinder component models. By using an electric guide rail to drive the slide to adjust the spacing, combined with the outward expansion design of the six-jaw chuck, it can accurately adapt to the shaft hole size of different cylinder component models, achieving stable clamping. At the same time, the slide moves along the annular groove, causing the cleaning components to surround the cylinder. With the deflection of the rotating seat and the adjustment of the spacing of the cleaning components by the electric push rod, it ensures that the cleaning components enter the inner cavity of various cylinders vertically and can move inside for cleaning, achieving thorough cleaning of the four corner areas. This greatly improves the versatility and cleaning coverage of the equipment, achieving adaptive clamping and all-round cleaning synergy, and is compatible with multiple cylinder models.

[0016] 2. This invention differs from the existing technology in that clamping and cleaning are separated. During the clamping process, the pump inside the mounting base sprays cleaning fluid through the clamping block opening. The inclined opening allows the cleaning fluid to be sprayed into the shaft holes at both ends of the cylinder from the gap between the clamping blocks. Through the alternating operation of clamping one end and cleaning the other end, the cleaning dead corners of the shaft hole are cleaned in a targeted manner, avoiding the problem of incomplete cleaning caused by the special structure of the shaft hole in traditional equipment. This achieves simultaneous clamping and local cleaning, overcoming the cleaning dead corners of the shaft hole.

[0017] 3. This invention innovatively adopts a multi-dimensional driven cleaning path design. The servo motor drives the cleaning cylinder to rotate 360°, and the electric push rod drives its axial reciprocating motion. In conjunction with the hub motor, the corrugated ring rotates, forcing the water outlet to move back and forth, forming a dynamically changing "cleaning water column". This design effectively expands the water column coverage area, breaks the limitations of traditional fixed path cleaning, reduces dead corners in the inner cavity, significantly improves the cleaning effect on the inner cavity of the cylinder parts, realizes a multi-dimensional dynamic cleaning path, and improves water column coverage and cleaning efficiency.

[0018] 4. During the cleaning process, this invention converts part of the cleaning liquid into foam through the nozzle and sprays it onto both sides of the "cleaning water column" to form a protective layer. This prevents the impact of the high-pressure water column from splashing up particulate impurities that could damage the surrounding inner cavity. At the same time, with the help of the gear transmission and magnetic control structure linked by the corrugated ring, the nozzle moves back and forth along the limiting rod. Due to the difference in magnetic force of the magnetic blocks, different movement distances are formed, ensuring that the foam accurately covers both sides of the water column. This improves cleaning safety while enhancing the targeting and comprehensiveness of foam protection, achieving a combination of foam protection and dynamic spraying to ensure cleaning safety.

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-9The device shown is a cleaning device for the internal cavity of a diesel engine cylinder block. It includes a housing 101, inside which a worktable 104 is installed. An electric guide rail 110 is installed at the top center of the worktable 104. Slides 105 are provided on both sides of the top of the electric guide rail 110. Mounting seats 116 are installed on the upper part of the adjacent side of each slide 105. A six-jaw chuck 126 is installed in the middle of each mounting seat 116. Multiple clamping blocks 121 are provided at the end of each six-jaw chuck 126. A stepper motor 127 is installed on one side of each six-jaw chuck 126 for adjusting the position of the clamping blocks 121. Fixed seats 124 are provided on the outer side of each six-jaw chuck 126, each mounted on one side of the mounting seat 116. Connecting rings 123 are rotatably connected to the ends of each fixed seat 124. The ends of the connecting rings 123 are fixed... The fixed base 124 is connected with evenly distributed connecting pipes 122. The end of each connecting pipe 122 away from the connecting ring 123 is connected to the clamping block 121. The side of each clamping block 121 close to each other is provided with evenly distributed openings 125. The internal channels of each opening 125 are all set in an inclined state. The top of each fixed base 124 is fixedly connected with a conduit 115. The clamping blocks 121 are used to clamp the cylinder body 109. The front and rear sides of the middle of the housing 101 are provided with observation windows 102. The front side of the housing 101 is equipped with a control panel 103. The control panel 103 is used to control the other driving components. The end of each conduit 115 away from the fixed base 124 is connected to the inside of the mounting base 116. The inside of each mounting base 116 is provided with a cavity for storing cleaning fluid. The inside of each mounting base 116 is equipped with a pump body. The pump body is connected to the conduit 115.

[0031] Furthermore, in specific implementation, the internal cavity of the cylinder block 109 can be cleaned using a cleaning machine. During operation, the cylinder block 109 can be placed inside the housing 101 through the observation window 102. Before this, the electric guide rail 110 needs to be started via the control panel 103. The threaded rod on the electric guide rail 110 is rotated by the end motor, which can move the slides 105 on both sides closer or further apart, allowing the cylinder block 109 to be moved into the housing 101 and placed between the slides 105 on both sides. Then, the electric guide rail 110 is started to bring the slides 105 closer together, and the clamping blocks 121 on the six-jaw chuck 126 can extend into the machining shaft holes on both sides of the cylinder block 109. Finally, the stepper motor 12 is started via the control panel 103. 7. The stepper motor 127 drives the six-jaw chuck 126 to work, thereby causing the clamping blocks 121 to expand outward. The clamping blocks 121 on both sides of the six-jaw chuck 126 can stably clamp the cylinder body 109. During the clamping process, the pump inside the mounting base 116 pumps cleaning fluid into the fixed base 124. The cleaning fluid can be sprayed out through the port 125 through the connecting ring 123, connecting pipe 122 and clamping blocks 121. The inclined port 125 allows the cleaning fluid to pass through the gap between the clamping blocks 121 and spray into the shaft holes at both ends of the cylinder body 109. By controlling the alternation of clamping one end and cleaning the other end, the shaft holes at both ends of the cylinder body 109 can be cleaned, achieving focused cleaning of cleaning dead corners, which is beneficial for practical use.

[0032] Among them, annular grooves 106 are opened on the outer side of the adjacent end of the slide 105, and multiple slide seats 111 are provided on the inner side of the annular grooves 106. The annular grooves 106 are provided with toothed grooves 117 and limiting grooves 120. Gears 118 are provided inside the slide seats 111. The bottom of the gears 118 are meshed with the toothed grooves 117. A motor is installed at the end of the slide seats 111. A rotating seat 112 is installed at the motor drive end. Guide rods 113 are fixedly connected to both sides of the adjacent end of the rotating seat 112. Multiple fixing plates 108 are slidably connected in the middle of the guide rods 113. A cleaning component is provided at the bottom of the fixing plates 108. A servo motor 114 is installed at the top of the fixing plates 108. Electric push rods 107 are installed between the fixing plates 108. The outer fixing plates 108 are connected to the rotating seat 112 through the electric push rods 107.

[0033] Furthermore, in specific implementation, the motor inside the slide 111 will start working, driving the gear 118 to rotate. Through the meshing between the gear 118 and the tooth groove 117, the two slides 111 can be driven to slide synchronously inside the annular groove 106, so that the cleaning component can perform cleaning work around the cylinder 109 along the annular groove 106. During this process, the motor installed at the end of the slide 111 can drive the rotating seat 112 to deflect, thereby realizing the deflection adjustment of the cleaning component. Furthermore, through the operation of each electric push rod 107, each fixed plate 108 can be driven to move along the guide rod 113, thereby adjusting the spacing between the cleaning components at the bottom of the fixed plate 108, so that the cleaning component can vertically enter the interior of different models of cylinder 109, thereby performing cleaning work inside the cylinder 109, and can perform moving cleaning inside the cylinder 109, thus thoroughly cleaning the four corner areas inside the cylinder 109, which is beneficial to practical use.

[0034] The cleaning components all include electric push rods 130, which are rotatably connected to the bottom of the fixed plate 108. The bottom drive end of the servo motor 114 is connected to the top of the electric push rod 130. The bottom telescopic end of the electric push rod 130 is fixedly connected to a cleaning cylinder 131. A hub motor is installed on the outer periphery of the telescopic end of the electric push rod 130. A connecting frame 132 is fixedly connected to the rotating part of the hub motor. A corrugated ring 137 is fixedly connected to the bottom of the connecting frame 132. A bottom ring 128 is fixedly connected to the bottom of the corrugated ring 137. A toothed groove 129 is opened on the lower part of the outer periphery of the bottom ring 128. The outer periphery of the cleaning cylinder 131 is fixedly connected to evenly distributed limit seats 133 and fixed frames. 140, the limiting seat 133 and the fixing frame 140 are alternately distributed. The inner side of the limiting seat 133 is provided with evenly distributed water outlets 134. The ends of the water outlets 134 are connected to the pump group inside the cleaning cylinder 131. The outer periphery of the water outlets 134 is equipped with connecting plates 138. The top of the connecting plates 138 is fixedly connected with a slide rod 143. The top of the slide rod 143 passes through the limiting seat 133. The slide rod 143 is slidably connected to the limiting seat 133. The top of the slide rod 143 is fixedly connected with a wear-resistant ball 141. The upper part of the outer periphery of the slide rod 143 is fitted with a return spring 142. The return spring 142 is located between the wear-resistant ball 141 and the limiting seat 133. The top of the wear-resistant ball 141 is in contact with the bottom ring 128.

[0035] Furthermore, in specific implementation, the internal pump unit of the cleaning cylinder 131 can draw the cleaning liquid inside the cleaning cylinder 131 and spray it out through the outlet 134. During this process, the servo motor 114 will start working, which will drive the electric push rod 130 and the bottom cleaning cylinder 131 to rotate, realizing 360° rotational cleaning of the inside of the cylinder 109. At the same time, the electric push rod 130 will start working simultaneously. The extension and retraction of the electric push rod 130 can drive the cleaning cylinder 131 to reciprocate axially inside the cylinder 109, further reducing cleaning dead angles. During the process, the hub motor on the outer periphery of the electric push rod 130 will start working, driving the connecting frame 132 to rotate. When the connecting frame 132 rotates, it will drive the bottom corrugated ring 137 to rotate, causing the corrugated ring 137 and the wear-resistant ball 141 to move relative to each other. Through the corrugated ring 137, the wear-resistant ball 141, the slide rod 143 and the connecting plate 138 can be forced to move back and forth, thereby driving the water outlet 134 to move back and forth. This can effectively increase the coverage area of ​​the "cleaning water column" and at the same time avoid the "cleaning water column" cleaning path being too rigid, which would affect the cleaning effect on the inner cavity of the cylinder part 109, and is beneficial to actual use.

[0036] The fixing frame 140 has a fixing strip 147 on the inner center of each fixing strip 147. Multiple magnetic blocks 139 and 148 are installed on the outer periphery of each fixing strip 147, with the magnetic blocks 139 and 148 distributed alternately. Rotating rods 119 are fixedly connected to the upper and lower parts of the fixing strip 147. Gears 136 are fixedly connected to the outer periphery of the upper rotating rod 119, and the gears 136 mesh with tooth grooves 129. Spray nozzles 135 are provided on both sides of the fixing strip 147, and connecting pieces 150 are fixedly connected to one side of each spray nozzle 135. The end of the connector 150 away from the nozzle 135 is connected to the pump unit inside the cleaning cylinder 131. The nozzle 135 is equipped with sliders 149 at the top and bottom. The sliders 149 are slidably connected inside the grooves 144. The upper and lower sides of the fixing frame 140 are provided with grooves 144. Limiting rods 145 are fixedly connected inside the grooves 144. The limiting rods 145 pass through the sliders 149 and are slidably connected to the sliders 149. Top springs 146 are sleeved on one side of the outer circumference of the limiting rods 145. The top springs 146 are all located on one side of the sliders 149.

[0037] Furthermore, in specific implementation, the pump unit inside the cleaning cylinder 131 can export a portion of the cleaning liquid through the connecting piece 150 and spray it out through the nozzle 135. The cleaning liquid is converted into foam when sprayed through the nozzle 135. The nozzle 135 can spray the foam onto both sides of the "cleaning water column" at the outlet 134, thereby protecting the surrounding areas of the cleaning part and preventing the impact of the "cleaning water column" from splashing up particulate impurities inside the cylinder 109, which could damage the surrounding inner cavity. This is beneficial for practical use. When the corrugated ring 137 rotates, it drives the bottom ring 128 fixed at the bottom to rotate. The toothed grooves 129 on the bottom ring 128 drive the meshing gears 136 to rotate synchronously. 36 can use the rotating rod 119 to drive the fixing strip 147 to rotate. When the fixing strip 147 rotates, the magnetic block 139 on the fixing strip 147 will cooperate with the magnetic coating on the nozzles 135 on both sides. Both magnetic block 139 and magnetic block 148 are magnetically attracted to the magnetic coating on the nozzles 135. The magnetic attraction can overcome the tension of the top spring 146, so that the nozzles 135 on both sides can move back and forth along the limiting rod 145. The magnetic blocks 139 and 148 are different in size and magnetic force, so that the nozzles 135 can move different distances. This allows the nozzles 135 to spray and cover both sides of the "cleaning water column" sprayed from the outlet 134 while moving to spray cleaning foam, which is beneficial for practical use.

[0038] Working principle:

[0039] In practical use, the internal cavity of the cylinder block 109 can be cleaned using a cleaning machine. During operation, the cylinder block 109 can be placed inside the housing 101 through the observation window 102. Before this, the electric guide rail 110 needs to be started via the control panel 103. The threaded rod on the electric guide rail 110 is rotated by the end motor, which can move the slides 105 on both sides closer or further apart, allowing the cylinder block 109 to be moved into the housing 101 and placed between the two slides 105. Then, the electric guide rail 110 is started to bring the slides 105 closer together, and the clamping blocks 121 on the six-jaw chuck 126 can extend into the machining shaft holes on both sides of the cylinder block 109. After that, the cylinder block 109 can be moved through the control panel 103. 3. Start the stepper motor 127. The stepper motor 127 drives the six-jaw chuck 126 to work, thereby causing the clamping blocks 121 to expand outward. The clamping blocks 121 on both sides of the six-jaw chuck 126 can stably clamp the cylinder body 109. Then, the motor inside the slide 111 will start working, driving the gear 118 to rotate. Through the meshing between the gear 118 and the tooth groove 117, the two slides 111 can drive the two slides 111 to slide synchronously inside the annular groove 106, so that the cleaning component can clean the cylinder body 109 along the annular groove 106. During this process, the motor installed at the end of the slide 111 can drive the rotating seat 112 to deflect, thereby realizing the deflection adjustment of the cleaning component. The operation of each electric push rod 107 drives each fixed plate 108 to move along the guide rod 113, thereby adjusting the spacing between the cleaning components at the bottom of the fixed plate 108. This allows the cleaning components to vertically enter the interior of different types of cylinder parts 109, enabling cleaning of the interior of the cylinder parts 109. Furthermore, the cleaning can be performed by moving the cleaning mechanism within the cylinder parts 109, ensuring thorough cleaning of the four corner areas, which is beneficial for practical use. During clamping, the pump inside the mounting base 116 pumps cleaning fluid into the fixed base 124, and the cleaning fluid is sprayed out through the port 125 via the connecting ring 123, connecting pipe 122, and clamping block 121. The inclined design... The inlet 125 allows the cleaning fluid to pass through the gap between the clamping blocks 121 and be sprayed into the shaft holes at both ends of the cylinder body 109. By controlling the alternation of clamping one end and cleaning the other, the shaft holes at both ends of the cylinder body 109 can be cleaned, achieving focused cleaning of hard-to-reach areas, which is beneficial for practical use. During the actual cleaning process, the pump unit inside the cleaning cylinder 131 can draw the cleaning fluid inside the cleaning cylinder 131 and spray it out through the outlet 134. During this process, the servo motor 114 will start working, which will drive the electric push rod 130 and the bottom cleaning cylinder 131 to rotate, achieving 360° rotational cleaning of the inside of the cylinder body 109. At the same time, the electric push rod 130 will start working simultaneously.The extension and retraction of the electric push rod 130 drives the cleaning cylinder 131 to reciprocate axially within the cylinder body 109, further reducing cleaning dead zones. During this process, the hub motor on the outer periphery of the electric push rod 130 starts working, driving the connecting frame 132 to rotate. The rotation of the connecting frame 132 drives the bottom corrugated ring 137 to rotate, causing relative movement between the corrugated ring 137 and the wear-resistant ball 141. The corrugated ring 137 forces the wear-resistant ball 141, the slide rod 143, and the connecting plate 138 to reciprocate, thereby driving the cleaning cylinder 131 to reciprocate. The reciprocating movement of the water outlet 134 effectively increases the coverage area of ​​the "cleaning water column" while preventing the cleaning path from becoming too rigid, which could affect the cleaning effect on the inner cavity of the cylinder 109. This is beneficial for practical use. During operation, the pump unit inside the cleaning cylinder 131 can export some of the cleaning fluid through the connecting plate 150 and spray it out through the nozzle 135. The cleaning fluid is converted into foam when sprayed through the nozzle 135, and the foam can be sprayed onto both sides of the "cleaning water column" at the water outlet 134, thereby achieving... The protection of the surrounding area of ​​the cleaning part prevents the impact of the "cleaning water column" from splashing particulate impurities inside the cylinder 109 and damaging the surrounding inner cavity, which is beneficial to actual use. When the corrugated ring 137 rotates, it will drive the bottom ring 128 fixed at the bottom to rotate. The toothed grooves 129 on the bottom ring 128 will drive the gears 136 meshing with it to rotate synchronously. The gears 136 can drive the fixed bar 147 to rotate via the rotating rod 119. When the fixed bar 147 rotates, the magnetic block 139 on the fixed bar 147 will interact with the spray on both sides. The magnetic coating on the nozzle 135 works in conjunction with magnetic blocks 139 and 148, which are magnetically attracted to the coating. This magnetic attraction overcomes the tension of the top spring 146, allowing the nozzles 135 on both sides to reciprocate along the limiting rod 145. The magnetic forces of magnetic blocks 139 and 148 are different, enabling the nozzles 135 to move different distances. This allows the nozzles 135 to effectively spray and cover both sides of the "cleaning water column" sprayed from the outlet 134 while simultaneously spraying cleaning foam, which is beneficial for practical use.
