[0023] The following will describe in detail the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0024] Please refer to Figures 1-4 , Figure 1 which is a schematic three-dimensional structure diagram of an oil injection device for a CDC shock absorber provided by an embodiment of the present utility model; Figure 2 which is a partial structure diagram of a code scanning component in an oil injection device for a CDC shock absorber provided by an embodiment of the present utility model; Figure 3 which is a schematic three-dimensional structure diagram of an oil injection component in an oil injection device for a CDC shock absorber provided by an embodiment of the present utility model; Figure 4 is Figure 3 The enlarged view at position A in. The oil injection device 1 for a CDC shock absorber of the present utility model includes a support assembly 11, a clamping seat 12, a code scanning component 13, and an oil injection component 14. The support assembly 11 includes a fixed seat 111 and a rotating table 112. The rotating table 112 is rotatably connected to the fixed seat 111. The clamping seat 12 is fixed to the rotating table 112 to clamp the CDC shock absorber 2. The code scanning component 13 and the oil injection component 14 are arranged around the fixed seat 111 on the outer side of the rotating table 112. When the rotating table 112 rotates, it drives the CDC shock absorber 2 to sequentially pass through the code scanning component 13 and the oil injection component 14. The code scanning component 13 includes a first bracket 131, a first support plate 132, and a code scanning gun 133. The first bracket 131 is fixed to the fixed seat 111. The first support plate 132 is slidably connected to the first bracket 131. The code scanning gun 133 is fixed to the first support plate 132.

[0025] When performing an oil injection operation on the CDC shock absorber 2, first manually place the CDC shock absorber 2 on the clamping seat 12 to fix the CDC shock absorber 2. Then, by rotating the rotating table 112, the CDC shock absorber 2 is rotated to the position of the code scanning component 13. When the code scanning gun 133 scans the two-dimensional code on the CDC shock absorber 2, the information of the CDC shock absorber 2 can be recorded, and the recorded information is transmitted to the oil injection component 14 so that the oil injection component 14 can temporarily store the code scanning record. When the rotating table 112 is rotated again to make the CDC shock absorber 2 rotate to the position of the oil injection component 14, the oil injection component 14 can retrieve the temporarily stored code scanning record to inject oil into the CDC shock absorber 2, so as to facilitate subsequent code scanning and tracing of the oil injection volume and whether oil has been injected into the CDC shock absorber 2 by scanning the two-dimensional code on the CDC shock absorber 2.

[0026] By fixing the barcode scanner 133 on the first support plate 132 and fixing the first support plate 132 on the first bracket 131, it is convenient to adjust the height of the barcode scanner 133 by adjusting the position of the first support plate 132 on the first bracket 131, so that the barcode scanner 133 can automatically scan the two-dimensional codes with different heights and the CDC shock absorbers 2 with different lengths. Combining with the rotation of the turntable 112, the CDC shock absorber 2 after being scanned is rotated to the oil injection assembly 14 for oil injection, thus realizing the automatic operation of scanning and oil injection for the CDC shock absorber. Compared with the manual barcode scanning method, the oil injection device 1 of the present utility model can improve the barcode scanning efficiency of the CDC shock absorber 2, and further improve the oil injection efficiency of the CDC shock absorber 2.

[0027] In the above embodiment, a driving device connected to the turntable 112 is provided on the fixed seat 111 to drive the turntable 112 to rotate according to a set program, thereby adjusting the position of the clamping seat 12, facilitating the loading and unloading operations of the CDC shock absorber 2 by the operator, and cooperating with the barcode scanning assembly 13 and the oil injection assembly 14 arranged around the turntable 112 to realize the automatic barcode scanning and automatic oil injection operations of the CDC shock absorber 2, improving the barcode scanning and oil injection efficiency. Among them, the driving device includes any one of a cam divider, a servo motor, and a stepping motor to drive the turntable 112 to rotate.

[0028] In an embodiment of the present utility model, the barcode scanning assembly 13 further includes a first driving member, and the first driving member is fixed on the first bracket 131 and connected to the first support plate 132 to drive the first support plate 132 to move up and down on the first bracket 131.

[0029] By driving the first bracket 131 to move up and down by the first driving member, the height of the barcode scanner 133 is adjusted, so that the barcode scanner 133 can scan two-dimensional codes with different heights and CDC shock absorbers 2 with different lengths. When performing barcode scanning, the barcode scanner 133 scans the CDC shock absorber 2 at the current height to detect whether there is a two-dimensional code at the current height. When the barcode scanner 133 does not scan the two-dimensional code, the first driving member drives the first bracket 131 to rise or fall to detect and scan the two-dimensional code at different heights, improving the flexibility of the barcode scanner 133 during barcode scanning.

[0030] In the above embodiment, the first driving member includes any one of a servo motor, a stepping motor, and a linear cylinder to drive the first support plate 132 to move up and down on the first bracket 131.

[0031] In an embodiment of the present utility model, the code scanning assembly 13 further includes at least two reversing seats and at least two connecting rods. The reversing seats are provided with two connecting holes for connecting the two connecting rods, and the directions of the two connecting holes are perpendicular to each other. One of the connecting rods is fixedly connected to the first support plate 132, and the other connecting rod is fixedly connected to the code scanning gun 133.

[0032] By using at least two reversing seats and at least two connecting rods to connect between the first bracket 131 and the code scanning gun 133, the angle of the code scanning gun 133 can be adjusted by adjusting the angle of the connecting rod on the reversing seat, so that the code scanning gun 133 can detect the two-dimensional code on the CDC shock absorber 2 from different angles, improving the flexibility of the code scanning gun 133 when scanning the code.

[0033] Please refer to Figure 2 , in an embodiment of the present utility model, the number of reversing seats is two, namely reversing seat d and reversing seat e, and the number of connecting rods is three, namely connecting rod a, connecting rod b and connecting rod c. Among them, one end of connecting rod a is connected to connecting hole d1 on reversing seat d, and the other end is connected to connecting hole e1 on reversing seat e. One end of connecting rod b is connected to connecting hole d2 on reversing seat d, and the other end is connected to the first support plate 132. One end of connecting rod c is connected to connecting hole e2 on reversing seat e, and the other end is connected to the code scanning gun 133. Thus, by rotating connecting rod a, the code scanning gun 133 can rotate around connecting rod a to adjust the code scanning angle of the code scanning gun 133. By rotating connecting rod b, the code scanning gun 133 can rotate around connecting rod b to adjust the code scanning angle of the code scanning gun 133. By rotating connecting rod c, the code scanning gun 133 can rotate around connecting rod c to adjust the code scanning angle of the code scanning gun 133.

[0034] In an embodiment of the present utility model, the oil injection assembly 14 includes a second bracket 1401, a second support plate 1402, a second driving member 1403 and an oil injection pipe 1404. The second bracket 1401 is fixed on the fixed seat 111. The second support plate 1402 is slidably connected to the second bracket 1401. The second driving member 1403 is fixed on the second bracket 1401 and connected to the second support plate 1402 to drive the second support plate 1402 to move up and down on the second bracket 1401. The oil injection pipe 1404 is fixed on the second bracket 1401 and communicated with an external fuel tank.

[0035] By slidably connecting the second support plate 1402 to the second support 1401 and connecting the second driving member 1403 to the second support plate 1402, the second support plate 1402 is driven to lift under the action of the second driving member 1403. By arranging the oil injection pipe 1404 on the second support plate 1402, the oil injection pipe 1404 is driven to lift when the second support plate 1402 lifts. Furthermore, when injecting oil into the CDC shock absorber 2, the second driving member 1403 drives the second support plate 1402 to descend, and the oil injection pipe 1404 is moved to the upper end of the CDC shock absorber 2, so that the oil fluid is injected into the interior of the CDC shock absorber 2 from the oil injection pipe 1404. After the oil injection is completed, the second driving member 1403 drives the second support plate 1402 to rise, so that when the turntable 112 rotates, the CDC shock absorber 2 is driven to be located below the oil injection pipe 1404, thereby realizing the automatic oil injection operation of the CDC shock absorber 2 and improving the oil injection efficiency.

[0036] In the above embodiment, the second driving member 1403 includes any one of a servo motor, a stepper motor, and a linear cylinder to drive the second support plate 1402 to lift on the second support 1401.

[0037] Please refer to Figure 3 and Figure 4 In the embodiment of the present utility model, the oil injection assembly 14 further includes an oil receiving plate 1405 and an oil receiving driving member 1406 fixed on the second support plate 1402. The oil receiving driving member 1406 is connected to the oil receiving plate 1405 to drive the oil receiving plate 1405 to move to the outlet of the oil injection pipe 1404 to close or open the outlet of the oil injection pipe 1404. When the oil receiving driving member 1406 drives the oil receiving plate 1405 to extend, the oil receiving plate 1405 closes the outlet of the main pipe to prevent the oil fluid on the oil injection pipe 1404 from dripping onto the fixing seat 111. When the oil receiving driving member 1406 drives the oil receiving plate 1405 to retract, the outlet of the oil injection pipe 1404 is opened, so that the oil fluid in the oil injection pipe 1404 can be injected into the CDC shock absorber 2.

[0038] In the embodiment of the present utility model, the oil injection assembly 14 further includes an oil temperature sensor, a return oil tank, an oil fluid circulation valve, and an oil fluid circulation three-way pipe 1407. The three pipe orifices of the oil fluid circulation three-way pipe 1407 are respectively communicated with the oil injection pipe 1404, the return oil tank, and an external oil tank. The oil temperature sensor is installed on the oil fluid circulation three-way pipe and is electrically connected to the oil fluid circulation valve to trigger the oil fluid circulation valve to open the oil path between the oil fluid circulation three-way pipe 1407 and the return oil tank and close the oil path between the oil fluid circulation three-way pipe 1407 and the oil injection pipe 1404 when detecting that the temperature of the oil fluid is higher than a preset value.

[0039] When refueling the CDC shock absorber 2, the temperature of the oil is detected by an oil temperature sensor. When the temperature is higher than the preset value, the oil circulation valve is triggered to open the oil circuit between the oil circulation tee 1407 and the oil return tank, and at the same time, the oil circuit between the oil circulation tee 1407 and the fuel injection pipe 1404 is closed, so that the oil flows into the oil return tank for cooling, avoiding excessive oil temperature and affecting the service life and quality of the CDC shock absorber 2. When the oil temperature sensor detects that the temperature of the oil is less than or equal to the preset value, the oil circulation valve is triggered to close the oil circuit between the oil circulation tee 1407 and the oil return tank, and at the same time, the oil circuit between the oil circulation tee 1407 and the fuel injection pipe 1404 is opened, so that the oil enters the fuel injection pipe 1404 and refuels the CDC shock absorber 2, realizing automatic refueling of the CDC shock absorber 2 and improving the refueling efficiency.

[0040] In an embodiment of the present invention, the fuel injection assembly 14 further includes a third bracket 1408, a third driving member 1409, and an oil storage cylinder 1410. The third bracket 1408 is fixed on the fixed seat 111. The third driving member 1409 and the oil storage cylinder 1410 are respectively fixed on the upper and lower sides of the third bracket 1408. The oil storage cylinder is provided with an oil inlet and an oil outlet. The oil inlet is communicated with an external oil tank, and the oil outlet is communicated with the oil circulation tee 1407. The third driving member 1409 is connected to the oil storage cylinder 1410 to drive the oil injection cylinder to pump oil.

[0041] When refueling the CDC shock absorber 2, when the third driving member 1409 is driven to extend, the third driving member 1409 extends into the oil storage cylinder 1410 and squeezes the oil to be extruded from the oil outlet, and the extruded oil enters the oil circulation tee 1407. Under the cooperation of the oil temperature sensor and the oil circulation valve, the oil enters the oil return tank or enters the CDC shock absorber 2 from the fuel injection port. When the third driving member 1409 is driven to contract, the third driving member 1409 retracts from the oil storage cylinder 1410, and the oil storage cylinder 1410 sucks oil from the oil inlet to the external oil tank to prepare for subsequent refueling operations.

[0042] In the above embodiment, the third driving member 1409 includes any one of a servo electric cylinder, a hydraulic cylinder, and a pneumatic cylinder, so that the third driving member 1409 expands and contracts in the oil storage cylinder 1410 to realize the oil pumping operation of the main oil cylinder.

[0043] In an embodiment of the present invention, the fuel injection assembly 14 further includes a pressure sensor 1411 fixed on the oil outlet to detect the oil pressure in the oil outlet, avoiding the explosion of the oil storage cylinder 1410 due to excessive oil pressure.

[0044] In an embodiment of the present utility model, the clamping seat 12 includes an upper clamping jaw 121, a lower clamping jaw 122, and a fourth bracket 123. The fourth bracket 123 is fixed on the rotating table 112.

[0045] By clamping the upper and lower sides of the CDC shock absorber 2 with the upper clamping jaw 121 and the lower clamping jaw 122 respectively, the CDC shock absorber 2 can be kept in a vertical state when fixed on the clamping seat 12, so as to facilitate the oil injection assembly 14 to inject oil into the CDC shock absorber 2 from the upper side of the CDC shock absorber 2. At the same time, it is also convenient for the operator to perform the loading and unloading operations.

[0046] In an embodiment of the present utility model, the number of the clamping seats 12 is set to at least two, and at least two clamping seats 12 are evenly distributed along the circumferential direction of the rotating table 112, so as to place the CDC shock absorbers 2 on at least two clamping seats 12 respectively, thereby realizing the simultaneous carrying out of the code scanning and oil injection operations on the CDC shock absorbers 2. That is, when the rotating table 112 rotates and one clamping seat 12 is located at the code scanning assembly 13 and the other clamping seat 12 is located at the oil injection assembly 14, the code scanning assembly 13 can scan the code of the CDC shock absorber 2 on the clamping seat 12, and the oil injection assembly 14 can inject oil into the CDC shock absorber 2 on the clamping seat 12, so as to improve the simultaneous carrying out of the code scanning and oil injection on the CDC shock absorbers 2 and improve the code scanning and oil injection efficiency.
