[0027] It needs to be pointed out that the hydraulic cylinder sleeve assembly line of the present utility model takes the cleaning and assembly of the sleeve parts of hydraulic cylinder as an example, and is not limited to the use range of the present utility model. The assembly line of the present utility model can also be used for cleaning and assembling other parts suitable for the present assembly line.

[0028] Truss manipulator 1 includes truss and manipulator 14, wherein the truss is used to control the movement of manipulator 14, so that manipulator 14 can grab the parts on cleaning assembly conveying line 2 or special tool 3;Manipulator 14 corresponds to the corresponding parts, such as chuck design for corresponding sleeve parts.

[0029] The first end and the last end of the cleaning and assembling conveying line 2 are arranged in the grabbing range of the truss manipulator 1, and the special tooling 3 is also arranged in the grabbing range below the truss manipulator 1; in this way, the truss manipulator 1 can grab the parts from the special tooling 3 to the cleaning and assembling conveying line 2 to complete the feeding, and can also grab the parts from the cleaning and assembling conveying line 2 to the special tooling 3 to complete the discharging.

[0030] The cleaning and assembling conveying line 2 adopts a single conveying line to continuously complete the cleaning and assembling of the parts on the same conveying line; the cleaning and assembling conveying line 2 is sequentially provided with the demagnetization device 21, the ultrasonic cleaning device 22 and the assembling station 23 from the first end to the last end, and the assembling station 23 can be manually assembled.

[0031] According to the above, the hydraulic cylinder disc sleeve assembly line has the following advantages: first, compared with the automatic mechanical arm, the truss manipulator 1 has large load and low cost, and can continuously carry large parts for feeding and discharging on the cleaning and assembling conveying line 2; second, the demagnetization device 21 can remove the iron filings adhered to the surface of the machined parts such as the disc sleeve of the hydraulic cylinder; third, compared with the atomizing nozzle, the cleaning of the ultrasonic cleaning device 22 is more thorough and comprehensive, and can complete the cleaning work with high quality; fourth, compared with the rotary table, the conveying line is more suitable for the automatic transportation and cleaning of large parts, and the assembling station can also be arranged on the conveying line.

[0032] Based on the above, the first end and the last end of the cleaning and assembling conveying line 2 are both in the grabbing range of the single truss manipulator 1, so that the single truss manipulator 1 can complete the feeding and discharging of the single cleaning and assembling conveying line 2, which can save more space and cost compared with the common truss manipulator 1 arranged at both ends of the single conveying line; further, the single cleaning and assembling conveying line 2 adopts a ring-shaped or U-shaped return structure, so that the first end and the last end of the single cleaning and assembling conveying line 2 are both in the grabbing range of the single truss manipulator 1; as an optimization, the cleaning and assembling conveying line 2 adopts a U-shaped conveying line, and the conveying lines at the first end and the last end are arranged in parallel and below the single truss manipulator 1, which can reduce the occupied space of the conveying line.

[0033] Based on the above, the truss manipulator 1 adopts an I-shaped three-axis truss, the X\Y\Z three axes of the truss are arranged perpendicular to each other, the truss is provided with a single moving cross beam 11, two parallel fixed cross beams 12 and a single sliding longitudinal beam 13, and the manipulator 14 is arranged at the bottom end of the sliding longitudinal beam 13, wherein the length direction of the moving cross beam 11 is the X axis, the length direction of the fixed cross beam 12 is the Y axis, and the length direction of the sliding longitudinal beam 13 is the Z axis; the I-shaped three-axis truss has the advantages of small space occupation, large load and fast movement, and is more suitable for feeding and discharging on the single cleaning and assembly conveying line 2. If the cleaning and assembly conveying line 2 adopts a U-shaped conveying line and the first end and the last end of the conveying line are both below a single truss manipulator 1, the first end and the last end of the cleaning and assembly conveying line 2 can be close to the two ends of the moving cross beam 11 (i.e. the two ends of the X axis and between the two parallel fixed cross beams 12).

[0034] Based on the above, the cleaning and assembly conveying line 2 adopts a conveying chain, which has the advantage of large gap and is more suitable for cleaning process; when the conveying chain passes through the ultrasonic cleaning equipment 22, the conveying chain and the parts can quickly drain the water after passing through the cleaning liquid; when the conveying chain passes through the hot air drying equipment 24 and the strong wind cooling equipment 25 mentioned below, more airflow can be passed through faster, increasing the drying / cooling efficiency.

[0035] Based on the above, the truss manipulator 1 is provided with a 3D vision device, which assists the truss manipulator 1 in grabbing the workpiece to feed and discharge from the cleaning and assembly conveying line 2.

[0036] Based on the above, between the ultrasonic cleaning equipment 22 and the assembly station 23 on the cleaning and assembly conveying line 2, there are also a hot air drying equipment 24 and a strong wind cooling equipment 25 in sequence; by separately arranging the hot air drying equipment 24 and the strong wind cooling equipment 25, higher power hot air drying equipment can be used for drying, and then the strong wind cooling equipment 25 is used for cooling, which improves the overall speed of drying and prevents the risk of burns when manual assembly is used later.
