TECHNICAL FIELD

[0001] The present application relates to the technical field of part cleaning, in particular to a part cleaning device. BACKGROUND

[0002] At present, in order to clean the pollutants on the surface of metal parts, metal part cleaning machines have been widely used in industry.

[0003] However, the existing cleaning machines on the market all need to use cleaning agents to clean metal parts, and the residues of cleaning agents after cleaning have a great impact on the environment and human health and safety, and are highly polluting. In addition, the existing cleaning machines on the market also have the disadvantages of high energy consumption, high noise, large floor area, etc., and are not suitable for the cleaning needs of some existing parts (metal parts with low degreasing requirements, only need to remove the residual oil and foreign matter on the surface).

[0004] Therefore, it is urgent to develop a technology to solve the above technical problems. SUMMARY

[0005] The purpose of the present application is to provide a part cleaning device to solve the technical defects of the prior art.

[0006] Therefore, the present application provides a part cleaning device, which comprises a hollow device box.

[0007] The front side of the device box is open, and a transparent front end cover is arranged thereon in a covering manner.

[0008] The inner cavity of the device box is provided with a horizontally distributed mounting table at the upper part.

[0009] The longitudinal middle part of the mounting table is provided with a horizontally distributed equipment mounting opening.

[0010] The front and rear sides of the horizontal middle part of the equipment mounting opening are welded and fixed with the upper end of the hollow intermediate pipe.

[0011] A reference base connecting rod is vertically and penetratively arranged in the intermediate pipe.

[0012] The top of the reference base connecting rod is provided with a reference base.

[0013] The reference base is located in the inner cavity of the device box.

[0014] The top of the reference base is provided with a vertically distributed workpiece to be cleaned.

[0015] A circular ring-shaped air knife is fixedly arranged above the device box.

[0016] The bottom of the air knife is surrounded by a downwardly open air outlet.

[0017] The top of the device box is provided with a vertical workpiece passing opening corresponding to the central through hole of the air knife;

[0018] The lower part of the device box is provided with a mechanical delay valve;

[0019] The mechanical delay valve is located directly below the reference base connecting rod.

[0020] From the above technical scheme provided by the present application, compared with the prior art, the present application provides a part cleaning device which is designed scientifically and can conveniently and reliably clean metal parts (specifically shaft parts, which are metal parts with low degreasing requirements and only need to remove residual oil and foreign matter on the surface) without using cleaning agents. The present application uses compressed air to directly clean the surface of the workpiece, which is safe and environmentally friendly, has no pollution, and also eliminates the energy consumption caused by the need to heat the cleaning agent in existing cleaning devices, achieving good technical effects of energy saving and emission reduction, and having great practical significance.

[0021] The device of the present application is a small and economical cleaning device for shaft parts. The present application uses counterweights and pulley devices to make a non-powered lifting mechanism to achieve the function of automatically lifting the workpiece after it is placed in the reference. At the same time, the present application uses an air knife device to install the air knife above the workpiece, which achieves the cleaning effect of the workpiece during the lifting and lowering process of the workpiece.

[0022] After inspection, the part cleaning device of the present application has small overall floor area, light weight, and convenient operation, and can be used in places with high production space requirements

[0023] After inspection, the part cleaning device of the present application has high safety and environmental protection. Since no solvent is used as a cleaning agent, and no electrical control and power device is needed like existing cleaning devices, the environmental and safety hazards caused by the use of toxic and dangerous chemicals (i.e. cleaning agents) are eliminated, and the risk of injury by power machinery is also eliminated.

[0051] The reference base 5 is located in the inner cavity of the device box 3;

[0052] The top of the reference base 5 is provided with a vertically distributed workpiece 17 to be cleaned (that is, the shaft part to be cleaned, which is a metal part with low degreasing requirement, only needing to remove the residual oil and foreign matter on the surface);

[0053] A circular air knife 1 is fixedly arranged above the device box 3;

[0054] The bottom of the air knife 1 is provided with a downwardly open air outlet;

[0055] The top of the device box 3 is provided with a vertically penetrating workpiece passing opening 303 corresponding to the center through hole of the air knife 1, which is used for passing the workpiece 17.

[0061] The two first lugs 61 are located between the two pulley fixed supports 90;

[0062] A counterweight 10 is arranged below each pulley 9;

[0063] The top of each counterweight 10 is provided with a second lifting lug 62;

[0064] The second lifting lug 62 of each counterweight 10 is connected to the first lifting lug 61 on the same side through a traction rope 13, and the traction rope 13 passes through the pulley 9 on the same side.

[0065] It should be noted that the upper end of the pulley 9 and the pulley fixing support 90 is pivotally connected using a connecting pin.

[0066] It should be noted that one end of the traction rope 13 is connected to the second lifting lug of the counterweight, vertically upward, then passes through the pulley 9, and the other end is connected to the first lifting lug of the reference base connecting rod vertically downward, so that the two sides of the reference base connecting rod are connected to the counterweight through the two traction ropes, and the function of balancing the center of gravity of the device is achieved.

[0067] Specifically, the left and right sides of each counterweight 10 are respectively provided with a vertically distributed counterweight limiting block 11;

[0068] The rear side of the counterweight limiting block 11 is fixedly connected (such as welded) to the rear panel of the device box 3;

[0069] It should be noted that the counterweight 10 is vertically placed in the device box 3, and the counterweight limiting block 11 is welded on the device box 3, which prevents the counterweight 10 from shifting or being stuck during the up and down movement. The transverse gap between the two counterweight limiting blocks 11 on both sides of each counterweight 10 is slightly larger than the transverse width of the counterweight 10.

[0070] Specifically, the middle and lower radial outer sides of the reference base connecting rod 6 are respectively welded with a circular first limiting block 81 and a second limiting block 82;

[0071] The second limiting block 82 is located directly below the intermediate conduit 70;

[0072] The first limiting block 81 is located in the inner cavity of the intermediate conduit 70;

[0073] The outer diameter of the first limiting block 81 is smaller than the inner diameter of the cylindrical intermediate conduit 70;

[0074] The outer diameter of the second limiting block 82 is greater than the inner diameter of the intermediate conduit 70;

[0075] The radial outer wall of the reference base connecting rod 6 is sleeved with a helical spring 7;

[0076] The bottom center of the intermediate conduit 70 is provided with a reference base connecting rod through hole;

[0077] The diameter of the reference base connecting rod through hole is greater than the outer diameter of the reference base connecting rod 6 and less than the outer diameter of the spring 7;

[0078] The top of the spring 7 is in contact with the bottom surface of the first limiting baffle 81;

[0079] The bottom of the spring 7 is in contact with the top side of the bottom of the intermediate guide pipe 70;

[0080] The spring 7 is located between the first limiting baffle 81 and the reference base connecting rod through hole of the bottom of the intermediate guide pipe 70.

[0081] In a specific implementation, the outer diameter of the first limiting baffle 81 is greater than the outer diameter of the spring 7;

[0082] In a specific implementation, the two first lugs 61 are located directly above the first limiting baffle 81;

[0083] It should be noted that for the present application, the intermediate guide pipe 70 passes through the reference base connecting rod 6, and the reference base connecting rod 6 has the first limiting baffle 81 and the second limiting baffle 82 distributed upward and downward, which can ensure that the reference base connecting rod 6 does not exceed the stroke when moving vertically up and down in the intermediate guide pipe 70 (i.e., a circular pipe).

[0084] It should be noted that between the reference base connecting rod 6 and the intermediate guide pipe 70 (i.e., a circular pipe), the spring 7 is provided, which is worn on the reference base connecting rod 6 and in contact with the inside of the intermediate guide pipe 70 (i.e., a circular pipe) on the outside. The spring 7 functions to automatically lift the reference base connecting rod 6, the reference base 5 thereon, and the workpiece 17 placed on the reference base 5 upward and reset under the action of the restoring force when the reference base connecting rod 6 moves downward to the lowest point.

[0085] In the present application, in a specific implementation, the front end cover 16 is a transparent cover plate.

[0086] It should be noted that the frontmost part of the device box is a layer of transparent acrylic cover plate as the front end cover 16.

[0087] In the present application, in a specific implementation, the top center position of the reference base 5 has a limiting protrusion protruding upward;

[0088] The lower end of the workpiece 17 has a downwardly open groove;

[0089] The shape and size of the limiting protrusion correspond to and match the shape and size of the groove at the lower end of the workpiece 17;

[0090] The limiting protrusion is inserted into the groove at the lower end of the workpiece 17.

[0091] Need to explain, the reference base 5 is the platform of the workpiece, the upper limit of the protruding just can and the workpiece 17 to be processed, ensure the workpiece after the placement of the stable.

[0092] In the present application, the two sides of the air knife 1 are connected with the upper end of the air knife mounting support frame 2 respectively.

[0093] The lower end of the air knife mounting support frame 2 is fixedly connected with the top of the mounting table 301 on the two sides of the front and rear after penetrating the workpiece through the opening 303.

[0094] Need to explain, the air knife mounting support frame 2, used to install the air knife 1, as the connecting piece between the air knife 1 and the mounting table 301 of the box body, through the bending and punching of stainless steel plate.

[0095] In the specific implementation, the bottom of the air knife 1 has a bolt mounting hole.

[0096] The air knife mounting support frame 2 is provided with a bolt through hole at the position corresponding to the bolt mounting hole at the bottom of the air knife 1.

[0097] The air knife mounting support frame 2 is fixedly connected with the bottom of the air knife 1 through the bolt.

[0098] The bolt is screwed and fixedly connected with the corresponding bolt mounting hole (which is an internal thread hole) after passing through the bolt through hole from bottom to top.

[0099] Need to explain, the air knife mounting frame 2 is a metal plate welded by an L-shaped plate and a U-shaped plate, and a bolt mounting hole is also arranged at the lower end of the air knife mounting support frame. The air knife mounting frame is installed on the mounting table 301 of the device box 3 by using the bolt.

[0100] In the present application, the bottom of the device box 3 is provided with a residual liquid collection outlet 14.

[0101] The residual liquid collection outlet 14 is in communication with the liquid inlet of the hollow external residual liquid collection container.

[0102] Need to explain, in the present application, the residual liquid collection outlet 14 is used as the collection port of the waste oil liquid cleaned out of the workpiece 17, that is, as the oil liquid recovery port, for collecting the oil liquid remaining after the workpiece is blown clean.

[0103] In the specific implementation, referring to Figure 6 As shown in the figure, the lower part of the left side panel of the device box 3 is provided with a pipeline inlet and outlet 304.

[0104] The upper part of the pipeline inlet and outlet 304 is provided with an inclined backflow plate 305.

[0105] Further, the transverse distance between the backflow plate 305 and the left side panel of the device box 3 gradually increases from top to bottom.

[0106] It should be noted that, for the present application, see Figure 5b As shown, under the action of the air flow blown by the air knife 1 (the flow direction A of the air flow, see Figure 5b As shown), the oil stains blown by the air knife 1 on the workpiece 17 will flow downward along the left and right inner walls of the box 3, and finally reach the bottom of the device box 3, and then flow out from the residual liquid collection outlet 14

[0107] Because the backflow plate 305 is arranged at the upper part of the pipeline inlet and outlet 304 (i.e. the opening), it can prevent the blown oil stains from flowing out of the device box of the present application from the pipeline inlet and outlet 304 (i.e. the opening).

[0108] In the present application, specifically, a mechanical delay valve 12 is arranged at the lower part of the device box 3.

[0109] The mechanical delay valve 12 is located directly below the reference base connecting rod 6.

[0110] Specifically, the left and right ends of the air knife 1 are respectively provided with an air nozzle 4.

[0111] It should be noted that the air nozzle 4 is connected to the air knife 1 through the external thread on the air nozzle connector, which supplies compressed air to the air knife, and there is one air nozzle on the left and one on the right, a total of two air nozzles.

[0112] Specifically, the two air nozzles 4 (each air nozzle is a two-way quick connector) are respectively connected to one end of a first connecting air pipe 151.

[0113] The other end of the two first connecting air pipes 151 is connected to the air outlet of the mechanical delay valve 12 after converging.

[0114] The air inlet of the mechanical delay valve 12 is connected to the air outlet of the external main air source (such as a compressed gas cylinder or an air compressor) through a hollow air inlet pipe 120.

[0115] Further, see Figure 7 As shown, the other end of the two first connecting air pipes 151 is respectively connected to the first interface and the second interface of a first three-way quick connector 41.

[0116] The third interface of the first three-way quick connector 41 is connected to one end of a second connecting air pipe 152.

[0117] The other end of the second connecting air pipe 152 is connected to the air outlet of the mechanical delay valve 12 through a second quick connector 42 (which is a two-way quick connector).

[0118] Further, the air inlet pipe 120 is connected with the air inlet of the mechanical delay valve 12 through the third quick connector 43.

[0119] Further, the air inlet pipe 120 and the second connecting air pipe 152 both pass through the pipe inlet and outlet 304 on the left side of the device box 3.

[0120] It should be noted that, for the present application, one end of the air inlet pipe 120 is connected with an external air source, and the other end is connected with the mechanical delay valve 12. After passing through the mechanical delay valve 12, the compressed air is discharged from the third quick connector 43, and then passes through the first three-way quick connector 41. Two air pipes (i.e., two first connecting air pipes 151) are branched from the other end of the first three-way quick connector 41, and then connected with the two quick connectors (i.e., air nozzles 4) of the air knife 1, respectively, so as to supply air to the air knife 1.

[0121] In specific implementation, the third quick connector 43 is an existing connector, which can be, for example, a special quick connecting air pipe pipe connector manufactured by SMC (China) Co., Ltd., with a model number of KQ2H.

[0122] The first three-way quick connector 41 is an existing connector, which can be, for example, a special quick connecting air pipe pipe connector manufactured by SMC (China) Co., Ltd., with a model number of KQ2U10.

[0123] In specific implementation, the upper and lower sides of the mechanical delay valve 12 are respectively embedded into the center through hole of the first mounting block 121 and the center through hole of the second mounting block 122.

[0124] The first mounting block 121 is located directly above the second mounting block 122.

[0125] The rear side of the first mounting block 121 and the rear side of the second mounting block 122 are fixedly connected (such as welded or other fixed connection methods) with the front side of the rear side panel of the device box 3.

[0126] It should be noted that the mechanical delay valve 12 is a mature valve in the prior art, which is used to control the opening or closing of the delivery gas pipe of the air supply (i.e., the main air source) of the air knife, that is, to control whether the compressed air is supplied to the air nozzle 4. The mechanical delay valve can be, for example, a mechanical delay valve with a model number of H862 produced by Wenzhou Cessna E-commerce Co., Ltd., which is a valve used to control the on-off of water and air.

[0127] It should be noted that the mechanical delay valve 12 is fixed on the device box 3 by the two mounting blocks. After the reference base connecting rod 6 moves to the lowest position, the bottom end of the reference base connecting rod 6 will push against the switch at the top of the mechanical delay valve 12, so as to open the valve.

[0128] The mechanical delay valve 12 is connected with the main air source at one end and connected with the air knife 1 through the air nozzle at the other end, and functions to control the opening and closing of the air source of the air knife.

[0129] In order to more clearly understand the technical solutions of the present application, the functions of some components are described below.

[0130] In the present application, the air knife 1 is a mature mechanical device in the prior art, which is used to blow off the oil liquid outside the workpiece 17; for example, a cleaning device (annular air knife) of model XH64 produced by Maiberson Technology (Shenzhen) Co., Ltd. can be used for cleaning various environments. In addition, air knives produced by other enterprises can also be used, as long as they can blow out strong and high-speed air flow downward, and can realize blowing off the oil liquid and foreign matter residues and other impurities outside the workpiece 17.

[0131] In the present application, the device box 3 is the shell of the entire mechanism, which is used to carry all the parts and install the related parts, and also serves as a function of recycling the waste oil liquid dripping from the workpiece 17;

[0132] In the present application, the reference base 5 is a work platform of the workpiece, which is a platform for carrying out workpiece processing and cleaning;

[0133] In the present application, the reference base connecting rod 6 is a main moving component, which is a main component for lifting and lowering the workpiece;

[0134] In the present application, the spring 7 is located outside the reference base connecting rod 6, which functions to provide a force for returning the workpiece;

[0135] In the present application, the second limit stop 82 is a limit for controlling the up-down operation of the mechanism;

[0136] In the present application, the pulley 9 is a component for guiding the movement of the traction rope 13;

[0137] In the present application, the counterweight 10 is a component for balancing the moving track of the workpiece;

[0138] In the present application, the counterweight limit stop 11 is used for guiding the counterweight in the up-down direction (i.e. the vertical direction) to move within a certain range;

[0139] In the present application, the traction rope 13 has two ends respectively connected with the counterweight 10 and the intermediate conduit 70.

[0140] In order to more clearly understand the technical solutions of the present application, the working principle of the present application is described below.

[0141] Referring to Figure 5aAs shown, in the initial state of the cleaning device provided by the present invention, the reference base 5 is located at the uppermost position, the counterweight 10 is located at the lowermost position, and the reference base connecting rod 6 and the reference base 5 at the top of the reference base connecting rod 6 are pulled by the traction rope 13.

[0142] See Figure 5b , Figure 5c As shown, when the workpiece 17 is placed on the reference base 5, the operator presses the workpiece 17 down by hand or with a tool that can press down. The workpiece 17 will move down together with the reference base 5 and the reference base connecting rod 6 until the lowest end of the reference base connecting rod 6 contacts the switch at the top of the mechanical delay valve 12, thus triggering the mechanical delay valve 12. During this process, the upper sections of the two traction ropes 13 are pulled into the intermediate guide tube 70 along the pulley 9.

[0143] When the mechanical delay valve 12 is triggered, compressed air is introduced into the air knife 1. According to the characteristics of the air knife 1, a downward air curtain is formed (the flow direction of the high-speed compressed airflow is as follows: A...). Figure 5b As shown), under the action of the air curtain, dirt on the surface of the workpiece (such as residual oil and foreign matter residue on the surface; the workpiece is a metal part that does not require high degreasing and only needs to remove residual oil and foreign matter residue on the surface) will be removed.

[0144] See Figure 5c As shown, after the workpiece is pressed to the lowest position, the hand is removed. Under the action of the counterweight 10 and the spring 7, the workpiece 17 and the reference base connecting rod 6 are subjected to an upward force and will move upward slowly and uniformly until the workpiece rises to the highest position (at this time, the top of the reference base 5 is in contact with the bottom of the air knife 1).

[0145] During the upward movement, all parts of the outer ring of the workpiece 17 can come into contact with the air curtain formed by the air knife (due to the action of the mechanical delay valve 12, the air knife will close after a delay). With the action of the air curtain and the up-and-down movement of the workpiece, the surface of the workpiece can be effectively cleaned.

[0146] Finally, the mechanical delay valve 12 will automatically stop the air supply, and the device of the present invention will end a cleaning operation and return to its initial state.

[0147] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
