Description

Technical Field

[0001] This utility model relates to supporting equipment for CNC machining centers, and more particularly to a cleaning and drying machine for automotive steering gear rods. Background Technology

[0002] The automotive steering gear rod, machined by a CNC machining center, has a complex structure including blind holes, threaded holes, flow channels, and steps. Therefore, impurities such as chips generated during machining are easily trapped in these structures. The presence of these impurities can affect subsequent assembly. For example, if impurities are present in the threaded hole, the robotic arm may encounter increased resistance when automatically tightening the screw. When this resistance reaches the robotic arm's set value, the program will automatically assume the screw is already tightened, mistaking a loose screw for a tightened one and proceeding to the next instruction. Therefore, to prevent impurities from affecting subsequent assembly, the automotive steering gear rod needs to be cleaned and dried after machining. Currently, ultrasonic cleaning is used to clean the steering gear rod, followed by manual drying by workers at a drying station. The above methods have disadvantages such as cumbersome operation, high labor intensity, low cleaning and drying efficiency, high labor costs, low degree of automation, and large space occupation.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will enable those skilled in the art to fully understand the scope of this disclosure.

[0025] Where there is no conflict, the various embodiments of this disclosure and the features thereof in the embodiments may be combined with each other. Example 1

[0026] For ease of description, this embodiment uses Figure 1 The left-hand direction is defined as "back". Figure 1 The right-hand direction is defined as "front". Figure 4 The top is defined as "left". Figure 4 The term "right" is defined below. In the description of this utility model, it should be noted that the terms "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figure 1 As shown, the automotive steering gear pole cleaning and drying machine described in this embodiment includes: a frame 1, with a housing 11 surrounding the frame 1. The housing 11 is fixed to the frame 1, and the frame 1 and all components of the automotive steering gear pole cleaning and drying machine are covered by the housing 11 to improve cleanliness and aesthetics. A processing chamber 2 is fixedly installed on the frame 1. The processing chamber 2 has a drain outlet at its bottom. The side wall of the processing chamber 2 has a side feed inlet 21 that communicates with the inner cavity of the processing chamber 2. A side opening is provided on the housing 11 opposite to the side feed inlet 21. A side-opening door device 3 is provided at the side opening to open or close the side feed inlet 21.

[0028] The function of the side-opening door device 3 is to open or close the side feed inlet 21. Since the side-opening door device 3 is mounted on the housing 11, this dictates that the processing chamber 2 must be located close to the inner wall of the housing 11. This embodiment uses... Figure 1 Taking the processing chamber 2 located near the inner wall of the front side panel of the housing 11 as an example, the side feed port 21 is located on the front side panel of the processing chamber 2, the side opening is located on the front side panel of the housing 11, and the side-opening door device is installed on the front side panel of the housing 11.

[0029] A rotating fixture seat 4 is provided at the bottom of the inner cavity of the processing chamber 2. The rotating fixture seat 4 has a bottom clamping fixture 5 for clamping the bottom of the car steering gear rod 10. The rotating fixture seat 4 is installed at the bottom of the inner cavity of the processing chamber 2 through a rotating support structure. A suspension support seat 6 is provided at the top of the inner cavity of the processing chamber 2. The suspension support seat 6 has a top clamping fixture 7 for clamping the top of the car steering gear rod 10. The suspension support seat 6 is suspended above the bottom clamping fixture 5 through a vertical displacement adjustment device, and the suspension support seat 6 can be moved up and down to the desired position through the vertical displacement adjustment device and then maintained in that position.

[0030] The rotating fixture 4 is driven to rotate by a rotating drive device. During the rotation, it can drive the car steering rod 10, which is clamped between the top clamping fixture 7 and the bottom clamping fixture 5, to rotate together.

[0031] A nozzle assembly is installed inside the processing chamber 2. Each nozzle in the nozzle assembly faces the steering gear lever 10, which is clamped between the top clamping fixture 7 and the bottom clamping fixture 5. Each fluid medium inlet in the nozzle assembly is connected to a branch pipe, and each branch pipe is connected to the spray water supply system and the compressed air supply system respectively through a corresponding water-air switching valve. The water-air switching valve is a two-inlet, one-outlet valve, a conventional valve that can be purchased directly from the market. The first inlet of the water-air switching valve is connected to the outlet of the spray water supply system, and the second inlet is connected to the outlet of the compressed air supply system. The water-air switching valve allows the nozzle assembly to switch between spray cleaning and air drying. That is, when the spray water supply system is connected to each nozzle assembly through the corresponding water-air switching valve, each nozzle assembly sprays spray water; when the compressed air supply system is connected to each nozzle assembly through the corresponding water-air switching valve, each nozzle assembly sprays compressed air.

[0032] In this embodiment, the spray water supply system can be any commercially available system that meets the function of spray cleaning; when the spray cleaning requires the water temperature to reach a certain temperature (above room temperature), a commercially available spray water supply system that can heat the spray water can be selected. The compressed air supply system can be any commercially available compressed air supply system that meets the function of supplying compressed air for water drying.

[0033] The automotive steering gear rod cleaning and drying machine is typically placed next to a CNC machining center, supplemented by a robotic arm. The robotic arm removes the CNC-machined automotive steering gear rod 10, and the side-opening door device 3 opens the side inlet 21. The robotic arm places the removed automotive steering gear rod 10 onto the bottom clamping fixture 5. After the top clamping fixture 7 completes clamping, the robotic arm leaves, and the side-opening door device 3 closes the side inlet 21. Then, the water supply system is connected to each nozzle group via water-air switching valves, spraying and cleaning the automotive steering gear rod 10 clamped between the top clamping fixture 7 and the bottom clamping fixture 5. After spraying and cleaning, the system is switched to compressed air supply system via water-air switching valves, connecting to each nozzle group, to air-dry the automotive steering gear rod 10 clamped between the top clamping fixture 7 and the bottom clamping fixture 5. During the spraying and air-drying process, the automotive steering gear rod 10 rotates at a set speed under the drive of the rotary drive device. After drying, the rotary drive device stops driving, and the side-opening door device 3 opens the side feed port 21. The robot grabs the car steering rod 10 clamped between the top clamping fixture 7 and the bottom clamping fixture 5. The top clamping fixture 7 moves upward and disengages from the car steering rod 10. The robot takes the car steering rod 10 out of the processing chamber 2 and sends it to the next workstation or to the designated collection area. Then, the next car steering rod taken out from the CNC machining center can be sprayed cleaned and air-dried.

[0034] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the structure of the side-opening door device 3 in this embodiment is as follows: a side door frame 31 is fixedly installed on the inner side wall of the housing 11 located on the left and right sides of the side opening or on the inner side wall of the processing chamber 2 located on the left and right sides of the side feed inlet 21. The side door frame 31 has an inwardly recessed groove 32. The left and right sides of the movable door 36 are respectively movably engaged in the groove 32 of the corresponding side door frame 31. The movable door 36 is installed on the housing 1 by a vertical drive device, and the movable door 36 can move upward along the groove 32 to open the side opening and the side feed inlet 21 or move downward along the groove to close the side opening and the side feed inlet 21 under the drive of the vertical drive device.

[0035] The vertical drive device described in this embodiment has the following structure: a vertical cylinder 33 is fixed to the outer wall of the housing 11 via an upper mounting base 34, and the piston rod end of the vertical cylinder 33 is fixed to the outer wall of the movable door 36 via a lower mounting base 35. The moving direction of the piston rod of the vertical cylinder 33 is the same as the moving direction of the movable door 36 along the slide groove 32. When the piston rod of the vertical cylinder 33 extends downward, it pushes the movable door 36 to move downward along the slide groove, closing the side feed port 21. Conversely, when the piston rod of the vertical cylinder 33 retracts upward, it pulls the movable door 36 to move upward along the slide groove, opening the side feed port 21.

[0036] The movable door 36 can be positioned in three ways. The first way is that the processing chamber 2 has its own front panel, without relying on the front panel of the housing 11 to form part of the processing chamber 2, and there is a gap between the front panel of the processing chamber 2 and the front panel of the housing 11. The two side door frames 31 are located on the inner side walls of the housing 11 on the left and right sides of the side opening. In this case, the movable door 36 is located in the gap between the front panel of the processing chamber 2 and the front panel of the housing 11.

[0037] The second form of the movable door 36 is: the processing chamber 2 borrows the front side plate of the housing 11, that is, the four side plates of the processing chamber 2 are formed by the combination of its own three side plates and the front side plate of the housing 11. At this time, the three side plates of the processing chamber 2, the front side plate of the housing 11, the bottom plate of the processing chamber 2 and the bottom plate of the processing chamber 2 form a box structure with a closed cavity. The two side door frames 31 are located on the inner side wall of the processing chamber 2 on the left and right sides of the side feed port 21. At this time, the movable door 36 is located inside the processing chamber 2.

[0038] The third form of the movable door 36 is: the processing chamber 2 has its own front side plate, without relying on the front side plate of the housing 11 to form part of the processing chamber 2, and the front side plate of the processing chamber 2 is in close contact with the front side plate of the housing 11 without any gap between them. The two side door frames 31 are located on the inner side wall of the processing chamber 2 on the left and right sides of the side feed port 21. In this case, the movable door 36 is also located inside the processing chamber 2.

[0039] In actual operation, considering factors such as leakage of the spray cleaning fluid medium, the second and third configurations of the movable door 36 are preferred.

[0040] The movable door 36 can be a regular, non-transparent door structure, or it can have a transparent, transparent window on the door. Setting a transparent, transparent window allows operators to clearly observe the spray cleaning and air drying operations in the treatment chamber 2.

[0041] This equipment combines spray cleaning and air drying functions, and has the advantages of compact structure, small footprint, simple operation, comprehensive functions, high degree of automation, high work efficiency, and good cleaning and drying effect.

[0042] Example 2 The automotive steering gear rod cleaning and drying machine described in this embodiment includes: a frame 1, with a housing 11 surrounding the frame 1. A processing chamber 2 is fixedly mounted on the frame 1. The side wall of the processing chamber 2 has a side feed inlet 21 communicating with the inner cavity of the processing chamber 2. A side opening is provided on the housing 11 opposite to the side feed inlet 21. A side-opening door device 3 is provided at the side opening to open or close the side feed inlet 21.

[0043] A rotating fixture seat 4 is provided at the bottom of the inner cavity of the processing chamber 2. The rotating fixture seat 4 has a bottom clamping fixture 5 for clamping the bottom of the car steering gear rod 10. The rotating fixture seat 4 is installed at the bottom of the inner cavity of the processing chamber 2 through a rotating support structure. A suspension support seat 6 is provided at the top of the inner cavity of the processing chamber 2. The suspension support seat 6 has a top clamping fixture 7 for clamping the top of the car steering gear rod 10. The suspension support seat 6 is suspended above the bottom clamping fixture 5 through a vertical displacement adjustment device, and the suspension support seat 6 can be moved up and down to the desired position through the vertical displacement adjustment device and then maintained in that position.

[0044] The rotating fixture 4 is driven to rotate by a rotating drive device. During the rotation, it can drive the car steering rod 10, which is clamped between the top clamping fixture 7 and the bottom clamping fixture 5, to rotate together.

[0045] like Figure 1 and Figure 2 As shown, the structure of the rotating tooling base 4 in this embodiment includes: a rotating support shaft 41, and the bottom clamping tool 5 is fixed on the rotating support shaft 41.

[0046] like Figure 2 and Figure 3 As shown, the rotating support structure includes: a fixed base 42 fixed in a mounting through hole at the bottom of the processing chamber 2; a vertically arranged rotating support shaft 41 supported in a support hole of the fixed base 42 by a bearing assembly; a sealing cover 43 fitted onto the rotating support shaft 41; the sealing cover 43 being fixedly connected to the top of the fixed base 42; and the sealing cover 43 and the rotating support shaft 41, as well as the sealing cover 43 and the fixed base 42, are sealed by corresponding sealing components. The sealing components can be commercially available sealing structures, as long as they meet the sealing requirements set here. The top of the rotating support shaft 41 extends beyond the top of the sealing cover 43. At this time, the bottom clamping fixture 5 is located above the fixed base 42.

[0047] The structure of the rotary drive device includes: a drive motor 44 fixed on the frame 1, and the drive motor 44 is connected to a rotary support shaft 41 extending out of the bottom of the fixed base 42 through a transmission structure.

[0048] The transmission structure can be belt drive, chain drive, etc. Here, we take synchronous belt drive as an example. The main drive synchronous pulley 45 is fixedly installed on the output shaft of the drive motor 44, and the driven synchronous pulley 46 is fixedly installed on the rotating part 41 below the extended fixed seat 42. The synchronous belt 47 is wound around the main drive synchronous pulley 45 and the driven synchronous pulley 46 to form a synchronous belt drive.

[0049] The automotive steering rod 10 has a main cylindrical channel that runs through the length of the automotive steering rod 10. This main channel is located in the central region of the automotive steering rod 10. When clamping the automotive steering rod 10, this main channel serves as the clamping area. The bottom clamping fixture 5 clamps the bottom region of the main channel, and the top clamping fixture 7 clamps the top region of the main channel. When the rotating fixture seat 4 is driven to rotate by the rotating drive device, causing the automotive steering rod 10, clamped between the top clamping fixture 7 and the bottom clamping fixture 5, to rotate together, the rotation center of the automotive steering rod 10 is at the center line of the main channel.

[0050] like Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, the structure of the bottom clamping fixture 5 in this embodiment is as follows: a bottom fixture seat 51 is fixedly provided on the top of the rotating support shaft 41, and a jaw assembly that can extend into the main channel of the car steering gear rod 10 is provided on the bottom fixture seat 51. The jaw assembly consists of three to four clamping jaws 52, and each clamping jaw 52 is evenly distributed around the rotation center of the rotating fixture seat 51.

[0051] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the structure of the suspension support 6 in this embodiment includes: a suspension rod 61, and the top clamping fixture 7 is fixed on the suspension rod 61.

[0052] The vertical displacement adjustment device includes a displacement adjustment cylinder 62, which can be mounted on the frame 1 outside the top of the processing chamber 2, or on the top surface of the processing chamber 2. The piston rod of the displacement adjustment cylinder 62 passes through the first top through hole in the top of the processing chamber 2 and extends into the processing chamber 2, then is fixedly connected to the suspension rod 61 via a connecting plate 63. A guide sleeve assembly 64 is also provided on the frame 1 above the processing chamber 2. The upper part of the suspension rod 61 moves through the second top through hole in the top of the processing chamber 2 and then passes through the guide hole of the guide sleeve assembly 64. The guide sleeve assembly 64 guides the vertical movement of the suspension rod 61, serving a guiding function.

[0053] When the top clamping fixture 7 needs to clamp the steering gear rod 10, the piston rod of the displacement adjusting cylinder 62 extends downward, pushing the suspension rod 61 downward. This causes the top clamping fixture 7 to move downward closer to the steering gear rod 10 clamped on the bottom clamping fixture 5, until the top clamping fixture 7 also presses against the steering gear rod 10. Conversely, when the top clamping fixture 7 needs to release the steering gear rod 10, the piston rod of the displacement adjusting cylinder 62 retracts upward, pulling the suspension rod 61 upward. This causes the top clamping fixture 7 to move upward away from the steering gear rod 10.

[0054] like Figure 6 and Figure 7 As shown, the structure of the top clamping fixture 7 in this embodiment is as follows: a fixing sleeve 71 is fitted on the suspension rod 61, the top of the fixing sleeve 71 has an upper connecting part 75, and the upper connecting part 75 is fixed to the bottom of the connecting plate 63.

[0055] The top clamping fixture 7 described in the embodiment further includes a top jaw seat 72, on which a through mounting hole 73 is provided. The top jaw seat 72 is fitted onto the fixed sleeve 71 through the mounting hole 73. A lower limiting member 74 is provided at the bottom of the fixed sleeve 71 to prevent the top jaw seat 72 from falling off the fixed sleeve 71. To reduce friction between the mounting hole 73 and the fixed sleeve 71, a groove 731 can be formed in the middle section of the mounting hole, and the diameter of the groove 731 is larger than the diameter of the mounting hole 73.

[0056] A spring 76 is fitted onto the fixing sleeve 71 between the upper connecting part 75 and the top of the top claw seat 72. When the top claw seat 72 abuts against the lower limiting member 74, the spring 76 has a certain amount of deformation, and in this state, the spring 76 has an upward displacement. That is, when the top claw seat 72 abuts against the lower limiting member 74, the spring 76 is not in its natural state, but is under a certain pressure. At this time, in addition to pressing down against the lower limiting member 74 under its own weight, the top claw seat 72 is also subjected to a downward spring force exerted by the spring 76. In this state, if an upward force is applied to the top claw seat 72, this force will force the spring 76 to continue to deform, that is, the spring 76 has the ability to deform further. In this way, it can be ensured that the top clamping fixture 7 has a certain buffering force when pressing against the car steering gear rod 10, thus protecting the car steering gear rod 10.

[0057] The top claw seat 72 has several top claws 77 extending into the main channel of the vehicle steering gear rod 10. Each top claw 77 is evenly spaced around the axis of the mounting hole 73, and the bottom outer contour of each top claw 77 forms an inverted conical outer contour 78 that is larger at the top and smaller at the bottom. The central area around each top claw 77 has a gap, and the bottom of the suspension rod 61 passes through the gap and extends downward beyond each top claw 77.

[0058] At this time, the axis of the mounting hole 73 on the top claw seat 72, the axis of the suspension rod 6, and the axis of the rotating support shaft 41 are all on the same straight line. When the car steering rod 10 is clamped in the top clamping fixture 7 and the bottom clamping fixture 5, the center line of the main channel of the car steering rod 10 is also on the same straight line as the axis of the mounting hole 73 on the top claw seat 72, the axis of the suspension rod 6, and the axis of the rotating support shaft 41.

[0059] A nozzle assembly is installed inside the processing chamber 2, with each nozzle facing the steering gear lever 10 clamped between the top clamping fixture 7 and the bottom clamping fixture 5. Each fluid medium inlet in the nozzle assembly is connected to a branch pipe, which is connected to the spray water supply system and the compressed air supply system respectively via a corresponding water-air switching valve. The components of the spray water supply system and the compressed air supply system can be installed at the rear or lower part of the processing chamber to achieve a compact overall structure.

[0060] The nozzle group described in this embodiment includes: a first nozzle group, a second nozzle group, and several fixed nozzle groups.

[0061] The fixed nozzle groups are distributed within the inner cavity of the processing chamber 2, and each fixed nozzle 8 in each fixed nozzle group faces the steering gear rod 10 clamped between the top clamping fixture 7 and the bottom clamping fixture 5, as shown below. Figure 2 As shown.

[0062] The steering gear lever 10 is a slender structure, so the fixed nozzle assembly can include: at least one vertical spray manifold 9, with several fixed nozzles 8 spaced from top to bottom on each vertical spray manifold 9. Each fixed nozzle 8 faces the steering gear lever 10 clamped between the top clamping fixture 7 and the bottom clamping fixture 5. Each vertical spray manifold 9 is connected to a connecting pipe 91 that provides a fluid medium to the vertical spray manifold 9. Each vertical spray manifold 9 and its corresponding connecting pipe 91 are made of metal, and the overall structure is fixed and will not deform under the pressure of the fluid medium. Therefore, the corresponding vertical spray manifold 9 can be fixed by directly fixing the connecting pipe 91. Of course, auxiliary connecting pipes or auxiliary connecting rods 92 can also be added to further support the corresponding vertical spray manifold 9. The fixed connecting pipe 91 and the auxiliary connecting rod 92 can be directly fixed to the inner wall of the processing chamber 2 by the fixing component, or they can be sealed through the corresponding through hole on the inner wall of the processing chamber 2 and then fixed to the frame 1 outside the processing chamber 2 by the fixing component.

[0063] like Figure 7 As shown, the first nozzle group in this embodiment includes: a first nozzle 65; the suspension rod 61 is a hollow tube structure; the first nozzle 65 is fixedly disposed at the bottom of the suspension rod 61, and the fluid medium inlet of the first nozzle 65 is connected to the hollow tube outlet of the suspension rod 61, and the hollow tube inlet of the suspension rod 61 is the fluid medium inlet end of the first nozzle group.

[0064] like Figure 8 As shown, the second nozzle group in this embodiment includes: a second nozzle 48; the rotating support shaft 41 is a hollow tube structure; the second nozzle 48 is fixedly disposed on the top of the rotating support shaft 41, and the fluid medium inlet of the second nozzle 48 is connected to the hollow tube outlet of the rotating support shaft 41, and the hollow tube inlet of the rotating support shaft 41 is the fluid medium inlet end of the second nozzle group.

[0065] When the car steering gear rod 10 is clamped between the top clamping fixture 7 and the bottom clamping fixture 5, the first nozzle 65 extends into the main channel from the top of the main channel of the car steering gear rod 10, and the second nozzle 48 extends into the main channel from the bottom of the main channel of the car steering gear rod 10 to spray and clean the main channel and blow it dry.

[0066] A more preferred solution is to also include an automatic robotic arm for loading and unloading the car rotator rod 10 into the processing chamber 2. The robotic arm for automatically grasping items is a mature product in the field of intelligent technology; it only requires matching the gripper part of the robotic arm with the corresponding gripper for grasping items. This is a mature technology, so the structure of the robotic arm will not be described in detail here. The control components of the automatic robotic arm, the drive components of the side-opening door device, the drive components of the rotary drive device, the drive components of the vertical displacement adjustment device, the controllers of each water-air switching valve, and the opening and closing control components of the spray water supply system and the compressed air supply system are all connected to the main control system to achieve automatic loading, automatic spray cleaning, automatic air drying, and automatic material unloading. The entire process takes only about 90 seconds and has advantages such as compact structure, small footprint, simple operation, comprehensive functions, high degree of automation, high work efficiency, and good cleaning and drying effect.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
