Description

Technical Field

[0001] The invention relates to the technical field of single-station cylinder cleaning machines, and in particular to a lifting and rotating mechanism and a cleaning device of a single-station cylinder cleaning machine. Background Art

[0002] During the engine production process, the engine cylinder block needs to be cleaned after each processing step is completed and before each assembly step to remove debris, dust and other impurities on the cylinder block to ensure the quality and stability of the mounting surfaces of the cylinder block and other components.

[0003] Due to the complex structure of the engine and the processing surfaces on the top, bottom, front, back, left, and right, all six sides of the engine need to be cleaned. To ensure the cleaning quality of the engine, after the top, front, back, left, and right sides are cleaned, the bottom of the engine needs to be turned over. At the same time, after cleaning, there is a lot of cleaning liquid in the blind hole of the engine, so the engine needs to be rotated to pour out the cleaning liquid in the blind hole.

[0004] Existing cylinder cleaning machines mainly use a robot to rotate the cylinder. Although the robot is more flexible, it is expensive, occupies a large space, and each rotation requires the lifting door of the cleaning machine to be opened, wasting a lot of time. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a lifting and rotating mechanism and a cylinder cleaning device for a single-station cylinder cleaning machine, which realizes the flipping of the cylinder inside the cleaning chamber, reduces the production cost of the cleaning equipment, and reduces the floor space occupied by the cleaning equipment.

[0006] The present invention is achieved through the following technical solutions:

[0007] A lifting and rotating mechanism for a single-station cylinder cleaning machine is provided, comprising a mounting frame and a lifting cylinder, wherein a lifting plate driven by the lifting cylinder is vertically slidably connected to the mounting frame via a guide rail, a rotating shaft penetrating the lifting plate is rotatably mounted on one side of the mounting frame via a rotating support, one end of the rotating shaft is connected to the output shaft of a rotating motor via a reducer, a rotating plate is fixed to the other end of the rotating shaft, and a locating pin for matching with a locating hole on the cylinder body and a rotating clamping cylinder for clamping the cylinder body are respectively mounted on the rotating plate on the side opposite to the rotating shaft.

[0008] This solution provides a rotating plate. After the rotary clamping cylinder clamps the cylinder body, the rotating motor drives the rotating shaft to rotate the rotating plate 180 degrees, and the cylinder body is flipped over to facilitate cleaning of the last side of the cylinder body, thereby realizing the flipping of the cylinder body inside the cleaning chamber. Compared with the prior art using a manipulator, the production cost of the cleaning equipment is reduced, and the floor space occupied by the cleaning equipment is reduced.

[0009] Furthermore, a distance sensor for detecting the distance between the cylinder body and the rotating plate and a pressure difference sensor for detecting the clamping degree between the cylinder body and the rotating plate are respectively installed on the rotating plate.

[0010] The distance sensor and the pressure difference sensor cooperate to locate the position of the cylinder body. The distance sensor is used to detect whether the cylinder body is close to the rotating plate, and the pressure difference sensor is used to detect whether the rotating clamping cylinder clamps the cylinder body and the rotating plate.

[0011] Furthermore, a cylinder support rod matching other positioning holes on the cylinder body is fixed on the rotating plate.

[0012] The cylinder support rod protects the cylinder to prevent the cylinder from hitting the cleaning chamber when the cylinder falls off accidentally.

[0013] Furthermore, two vertical guide rails are arranged on the mounting frame, and sliding blocks respectively matched with the vertical guide rails are fixed on the lifting plate.

[0014] The two vertical guide rails on the mounting frame cooperate with the sliders provided on the lifting plate to realize the vertical movement of the lifting plate, thereby driving the rotating plate and the cylinder body to be lifted as a whole, so as to facilitate the flipping of the cylinder body.

[0015] Furthermore, one end of the rotating support is fixed to the lifting plate, and the other end of the rotating support is equipped with a reducer and a rotating motor through a fixing frame, and the rotating support is rotatably connected to the rotating shaft through an angular contact bearing.

[0016] An angular contact bearing is arranged inside the rotating support to facilitate the rotational connection of the rotating shaft. The rotating support is installed with a reducer through a fixed frame. The reducer is used to adjust the speed of the rotating motor and increase the torque.

[0017] A cleaning device using a lifting and rotating mechanism of a single-station cylinder cleaning machine includes a cleaning chamber, a first opening is provided on the front of the cleaning chamber, a second opening is provided on the back of the cleaning chamber, and a vertically movable accordion is fixed to the back through a mounting plate at the second opening, a third opening is provided on the mounting plate, a mounting frame is fixed outside the cleaning chamber and directly opposite to the back of the cleaning chamber, a rotating plate is arranged in the cleaning chamber, a rotating shaft passes through the cleaning chamber through the second opening and the third opening, and the rotating shaft is sealed and rotatably connected to the mounting plate at the third opening.

[0018] This solution is achieved by setting up a cleaning chamber in conjunction with a rotating mechanism for cleaning. The back of the rotating plate is sealed and cleaned by a straight-line accordion to prevent the cleaning liquid from overflowing from the cleaning chamber. The straight-line accordion is used for protection to avoid splashing of the cleaning liquid to the outside of the cleaning chamber, thereby ensuring the working environment of the factory production workshop.

[0019] Furthermore, a guide frame is provided between the rotating plate and the accordion for the air pipe of the rotating clamping cylinder and the sensor line to pass through.

[0020] The guide frame is used to store the air pipe and the line to prevent the air pipe or the line from being entangled or curled when the rotating plate rotates, thereby affecting the use.

[0021] Furthermore, it also includes a first conveying mechanism and a second conveying mechanism, the first conveying mechanism and the second conveying mechanism are vertically arranged, the second conveying mechanism is opposite to the opening of the cleaning chamber, one end of the second conveying mechanism extends to the inner wall on the side opposite to the opening, and the other end is connected to the end of the first conveying mechanism.

[0022] The first conveying mechanism is used to convey the cylinder body to be cleaned to the cleaning chamber, and the second conveying mechanism is used to convey the cylinder body to be cleaned into the cleaning chamber. The first conveying mechanism and the second conveying mechanism cooperate to realize automatic loading and unloading of the cylinder body, thereby improving the cleaning efficiency.

[0023] Preferably, a third conveying mechanism is further included, and the third conveying mechanism and the first conveying mechanism are located on the same straight line.

[0024] The third conveying mechanism is used to convey the cleaned cylinder body out of the cleaning chamber, thereby reducing manual labor intensity and improving cleaning efficiency.

[0025] Furthermore, the first conveying mechanism, the second conveying mechanism and the third conveying mechanism are all roller conveying lines.

[0026] The roller conveyor line has a simple structure and is easy to operate, which helps to reduce production costs.

[0027] Beneficial effects of the present invention:

[0028] Compared with the prior art, the present invention utilizes a positioning pin to position the cylinder body, a rotating clamping cylinder to clamp the cylinder body, and a rotating motor to drive the rotating plate and the cylinder body to flip 180 degrees as a whole, thereby realizing the flipping of the cylinder body inside the cleaning chamber. There is no need to open the lifting door of the cleaning chamber for each rotation, thereby saving cleaning time, while reducing the production cost of the cleaning equipment and the floor space occupied by the cleaning equipment.

[0029] The cleaning device adopts an accordion-like waterproof structure, which separates the cylinder lifting and rotation front and back, ensuring that the cleaning chamber is leak-proof and meeting the waterproof grade requirements for the rotating servo motor and lifting cylinder.

DETAILED DESCRIPTION

[0037] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0038] A lifting and rotating mechanism of a single-station cylinder cleaning machine includes a mounting frame 14 and a lifting cylinder 9. A lifting plate 10 driven by the lifting cylinder 9 is vertically slidably connected to the mounting frame 14 via a guide rail. Two vertical guide rails 19 are arranged on the mounting frame 14. Slide blocks 11 respectively matching the vertical guide rails 19 are fixed on the lifting plate 10.

[0039] The lifting plate 10 is rotatably mounted on one side of the mounting frame 14 through a rotating support 16 with a rotating shaft 15 penetrating the lifting plate 10. One end of the rotating shaft 15 is connected to the output shaft of the rotating motor 13 through a reducer 12. The rotating motor 13 is a servo motor. The other end of the rotating shaft 15 is fixed with a rotating plate 4. The rotating plate 4 is respectively installed with a positioning pin 1 for matching with the positioning hole on the cylinder body and a rotating clamping cylinder 2 for clamping the cylinder body on the side opposite to the rotating shaft 15. Among them; the positioning pin 1 includes at least two conical positioning pins, and the two positioning pins 1 are respectively fixed on the rotating plate 4. The rotating plate 4 is also fixed with a cylinder support rod 3 matching with other positioning holes on the cylinder body. The cylinder support rod 3 is arranged vertically with the rotating plate 4, and the other positioning holes on the cylinder body are used for the cylinder support rod 3 to pass through, which can protect the cylinder body and prevent the cylinder body from hitting the cleaning chamber when the cylinder body accidentally falls off.

[0040] The rotating plate 4 is respectively provided with a distance sensor 5 for detecting the distance between the cylinder body and the rotating plate 4 and a pressure difference sensor 20 for detecting the clamping degree between the cylinder body and the rotating plate 4. The distance sensor 5 positions the cylinder body laterally and cooperates with the pressure difference sensor 20 to detect the clamping condition of the cylinder body.

[0041] One end of the rotating support 16 is fixed to the lifting plate 10 , and the other end of the rotating support 16 is installed with a reducer 12 and a rotating motor 13 via a fixing frame 18 . The rotating support 16 is rotatably connected to the rotating shaft 15 via an angular contact bearing 17 .

[0042] A cleaning device using a lifting and rotating mechanism of a single-station cylinder cleaning machine includes a cleaning chamber 21, a first opening 22 is provided on the front of the cleaning chamber 21, a second opening is provided on the back of the cleaning chamber 21, and a vertically movable accordion 7 is fixed to the back through a mounting plate at the second opening, a third opening is provided on the mounting plate, a mounting frame 14 is fixed outside the cleaning chamber 21 and faces the back of the cleaning chamber 21, a rotating plate 4 is arranged in the cleaning chamber, a rotating shaft 4 passes through the cleaning chamber through the second opening and the third opening, and the rotating shaft 4 is sealed and rotatably connected to the mounting plate at the third opening.

[0043] A guide frame 6 for the air pipe of the rotating clamping cylinder 2 and the sensor line to pass through is also provided between the rotating plate 4 and the straight organ 7. The guide frame 6 can comb the air pipe of the cylinder to prevent the air pipe from being folded and blocked during the rotation process.

[0044] The cylinder cleaning device further includes a first conveying mechanism 23 and a second conveying mechanism 24, which are arranged vertically, and the second conveying mechanism 24 is directly opposite to the opening of the cleaning chamber 21, and one end of the second conveying mechanism 24 extends to the inner wall on the side opposite to the first opening 22, and the other end is connected to the end of the first conveying mechanism 24. It also includes a third conveying mechanism 25, which is located on the same straight line as the first conveying mechanism 23. Among them: the first conveying mechanism 23, the second conveying mechanism 24 and the third conveying mechanism 25 are all roller conveying lines.

[0045] The cylinder body is transported into the second transport mechanism 24 through the first transport mechanism 23, and the second transport mechanism 24 transports the cylinder body into the cleaning chamber 21 for cleaning. After the five surfaces of the cylinder body are cleaned, the cylinder body moves to the rotating station on one side of the cleaning chamber 21 where the rotating plate 4 is installed. After the cylinder body reaches the position, the positioning hole on the flywheel side cleaning surface of the cylinder body penetrates into the conical positioning pin 1, and the positioning surface on the conical positioning pin 1 and the positioning pin 1 perform lateral positioning for forward and backward movement. After the distance sensor 5 on the positioning pin 1 detects that the cylinder body is in place, the rotary clamping cylinder 2 performs rotary clamping, and the pressure difference sensor 20 can be used to detect the clamping degree of the rotary clamping cylinder 2 on the cylinder body. The lifting cylinder 9 lifts the cylinder body upward. After it is raised to a certain height, the lifting cylinder 9 detects that the cylinder is in place, and the servo motor 13 starts to drive the rotating shaft 15 to drive the rotating plate 4 to rotate, so that the cylinder body can be rotated. After rotating 180°, the upper surface of the cylinder body after flipping can be cleaned. In order to prevent the cleaning liquid from splashing outside the cleaning chamber during the cleaning process, a gusset 7 is used to protect it, thereby preventing the cleaning liquid from splashing outside the cleaning chamber and ensuring the working environment of the factory production workshop.
