Description

Technical Field

[0001] This invention belongs to the field of automated parts cleaning technology, specifically relating to a cleaning device for small and medium-sized end cap parts. Background Technology

[0002] With the increasing development of manufacturing and the continuous evolution of machining centers, the relatively primitive manual cleaning of parts has gradually disappeared in front-line manufacturing, replaced by more efficient specialized cleaning machines. Traditional cleaning machines can be roughly divided into three types: The first type is the traditional through-feed cleaning machine. During cleaning, the workpiece passes through numerous fixed nozzles, which spray washing liquid to clean the workpiece. The workpiece only moves on a conveyor belt, resulting in a limited cleaning area and generally poor cleaning effect. Furthermore, through-feed cleaning machines are typically large and require a significant floor space, which is inconvenient in practical applications. The second type is the rotary sweeping spray machine. When the device moves, the parts remain stationary. The nozzles are connected to a rotating body that rotates at a constant speed. Water flows across the cleaning surface of the parts. Except when the water flow is perpendicular to the workpiece plane, the impact force is greatest; at other times, due to angular deviations, the water flow is not significant. The impact force is reduced to zero, and the impact force is minimal at the boundaries on both sides of the part, making it difficult to accurately clean every point to be cleaned during the cleaning process; the third method is fixed-point direct spraying, where the part and the nozzle are fixed. By adjusting the number, position and angle of the nozzles, the water flow is directly aimed vertically at the point on the part that needs to be cleaned. This method is generally used for cleaning important parts. The nozzles are specially customized for the part. Although fixed-point direct spraying can achieve cleaning of specific points to a certain extent, its tooling design is often only for specific parts and lacks sufficient adaptability, making it unsuitable for parts of different specifications. Summary of the Invention

[0003] The present invention aims to provide a cleaning device for small and medium-sized end cap parts, and to solve various technical problems existing in the existing cleaning machines.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A small and medium-sized end cap parts cleaning device includes a frame and a control system. The frame is equipped with a parts clamping assembly, an angle-adjustable spray assembly, a split pump and a washing liquid tank.

[0006] At least one set of part clamping assemblies is provided, which are used to clamp and fix the parts to be cleaned;

[0007] The angle-adjustable spraying assembly includes a channel steel mounting body and a rotary drive mechanism. Several nozzles are provided on the channel steel mounting body. All the nozzles are arranged side by side in the vertical direction and face the part clamping assembly. The rotary drive mechanism is used to drive the channel steel mounting body to rotate around its length.

[0008] The inlet of the split pump is connected to the washing liquid tank through the inlet pipe, and the outlet of the split pump is connected to all the nozzles through the outlet pipe.

[0009] The control system is connected to the rotary drive mechanism and the split pump control.

[0010] Furthermore, the part clamping assembly includes a servo motor and a turntable clamp. The servo motor is mounted on the frame via a servo motor connector, and the turntable clamp is set on the spindle of the servo motor. The turntable clamp is provided with several positioning pins and positioning ridges, and the control system is connected to the servo motor.

[0011] Furthermore, the aforementioned small and medium-sized end cap parts cleaning device also includes a wastewater recovery mechanism, which includes a funnel and a wastewater tank. A rectangular opening is provided on the top of the frame, and the funnel is a four-sided pyramidal structure. The top of the funnel is installed in the rectangular opening, and a leakage hole is provided at the center of the bottom of the funnel. The wastewater tank is located on the frame below the funnel.

[0012] The angle-adjustable injection assembly and the part clamping assembly are both located above the funnel.

[0013] Furthermore, the wastewater tank is connected to the inlet of the split pump via a delivery pipeline, and a filter is installed on the delivery pipeline, with a filter element inside the filter.

[0014] Furthermore, a vertical tube is fixed to the leakage hole of the funnel by a bracket; the lower end of the channel steel mounting body is installed on the upper end of the vertical tube by rotation, and the liquid outlet pipe passes through the vertical tube;

[0015] The rotation drive mechanism consists of a connecting seat and four sets of electric cylinder push assemblies. The connecting seat has a rectangular structure, and its four corners are connected to the lower end of the channel steel mounting body by pins. The four sets of electric cylinder push assemblies are evenly distributed at the rectangular opening. Each set of electric cylinder push assemblies includes an electric push rod and a mounting seat.

[0016] Compared with existing technologies, the advantages of this invention are as follows: This invention is mainly aimed at parts that need to be cleaned after machining. It mainly includes a frame, a part clamping assembly, an angle-adjustable spray assembly, a split pump, and a washing liquid tank, etc., with a small overall footprint, allowing it to be directly embedded into the entire production line, thereby improving production efficiency and flexibility; This invention can perform more detailed cleaning on each part, ensuring that each part is thoroughly cleaned; This invention eliminates the need to design and manufacture corresponding nozzle tooling for each part of different specifications, which not only saves manufacturing costs but also greatly improves the versatility and flexibility of the cleaning device, enabling it to adapt to the cleaning needs of parts of various specifications.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The present invention will be further described in detail below with reference to the embodiments.

[0024] like Figure 1-4 As shown, a specific embodiment of the cleaning device for small and medium-sized end cap parts provided by the present invention is as follows:

[0025] A small and medium-sized end cap parts cleaning device includes a frame 1 and a control system. The frame 1 is equipped with a parts clamping assembly 2, an angle-adjustable spray assembly, a split pump 3 and a washing liquid tank.

[0026] The parts clamping assembly 2 is provided in two sets. The parts clamping assembly 2 is used to clamp and fix the parts 4 to be cleaned. The parts clamping assembly 2 includes a servo motor 5 and a turntable clamp 6. The servo motor 5 is mounted on the frame 1 through the servo motor connector 7. The turntable clamp 6 is set on the spindle of the servo motor 5. The turntable clamp 6 is provided with several positioning pins 8 and positioning edges 9. The parts 4 to be cleaned can be clamped and fixed through the positioning pins 8 and positioning edges 9. The control system is connected to the servo motor 5. The servo motor 5 drives the turntable clamp 6 to rotate at a precise small angle and constant speed, ensuring the stability and consistency of the rotation process.

[0027] The angle-adjustable spray assembly includes a channel steel mounting body 10 and a rotation drive mechanism. Several nozzles 11 are provided on the channel steel mounting body 10. All the nozzles 11 are arranged side by side in the vertical direction and face the part clamping assembly 2, so that the nozzles 11 can spray a strong water flow in the direction of the part clamping assembly 2. At the same time, the rotation drive mechanism is used to drive the channel steel mounting body 10 to rotate around its length direction, so that the nozzles 11 on the channel steel mounting body 10 rotate.

[0028] The inlet of the split pump 3 is connected to the washing liquid tank through the inlet pipe, and the outlet of the split pump 3 is connected to all the nozzles 11 through the outlet pipe 13; the control system is connected to the rotation drive mechanism and the split pump 3, and the control system can be a PLC controller.

[0029] The working process of a small and medium-sized end cap parts cleaning device in this embodiment is as follows: The split pump 3 is started, and the split pump 3 starts to work, drawing the washing liquid from the washing liquid tank and delivering it to the nozzle 11 through the liquid outlet pipe 13. The nozzle 11 then sprays high-pressure washing liquid to ensure that the dirt on the surface of the parts 4 can be effectively removed. In addition, under the drive of the rotation drive mechanism, the channel steel mounting body 10 can rotate, driving the nozzle 11 to rotate, so that the washing liquid sprayed by the nozzle 11 can evenly cover every corner of the parts 4. At the same time, under the drive of the servo motor 5, the turntable clamp 6 and the parts 4 on it will also rotate at a certain angle to ensure that the washing water flow can be continuously and vertically aimed at the points on the parts 4 that need to be cleaned for cleaning, so as to achieve a thorough cleaning effect.

[0030] As another embodiment of the present invention, the small and medium-sized end cap parts cleaning device in this embodiment also includes a sewage recovery mechanism. The sewage recovery mechanism includes a funnel 14 and a sewage tank 15. A rectangular opening is provided on the top of the frame 1. The funnel 14 has a four-sided pyramidal structure. The top of the funnel 14 is installed in the rectangular opening. A leakage hole is provided at the center of the bottom of the funnel 14. The sewage tank 15 is provided on the frame 1 below the funnel 14.

[0031] The angle-adjustable spray assembly and the parts clamping assembly 2 are both located above the funnel 14. The wastewater tank 15 is connected to the inlet of the split pump 3 via a delivery pipe, and a filter 17 is installed on the delivery pipe, with a filter element inside the filter 17.

[0032] When the washing liquid is sprayed from the nozzle 11, some of the washing liquid will fall into the funnel 14 along with the dirt on the surface of the part 4. Then, it will fall into the wastewater tank 15 through the leakage hole at the bottom of the funnel 14. After being filtered by the filter 17, the clean washing liquid can be pumped out and reused by the split pump 3. This design not only avoids the sprayed washing liquid from splashing everywhere and causing pollution, but also enables the washing liquid to be recycled.

[0033] In addition, the structure and installation of the rotation drive mechanism in this embodiment are as follows: the vertical tube 18 is fixed to the leakage hole of the funnel 14 by a bracket; the lower end of the channel steel mounting body 10 is installed on the upper end of the vertical tube 18 by rotation, and the liquid outlet pipe 13 passes through the vertical tube 18.

[0034] The rotation drive mechanism consists of a connecting seat 19 and four sets of electric cylinder push assemblies. The connecting seat 19 has a rectangular structure, and its four corners are connected to the lower end of the channel steel mounting body 10 by pins 20. The four sets of electric cylinder push assemblies are evenly distributed at the rectangular opening. Each set of electric cylinder push assemblies includes an electric push rod 21 and a mounting seat 22. The mounting seat 22 is fixed on the frame 1, and the electric push rod 21 is mounted on the mounting seat 22. The push rod end of the electric push rod 21 is hinged to the pin 20. The control system is connected to the four sets of electric cylinder push assemblies.

[0035] When the channel steel mounting body 10 needs to be rotated, the control system controls the four sets of electric push rods 21 to extend and retract synchronously and equally. This coordinated movement can effectively drive the channel steel mounting body 10 equipped with nozzles 11 to rotate. During this process, the rotation of the channel steel mounting body 10 is smooth and uniform, ensuring stable water jetting. Unlike traditional designs, this invention simplifies the assembly process of components by separating the water pipe and the rotation drive mechanism, reducing the use of materials and thus effectively reducing the overall manufacturing cost. In addition, this improved design also brings higher reliability and maintainability.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
