[0022] The following provides a detailed description of the specific embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model and do not limit the present utility model.
[0023] Please refer to Figures 1 - 3 , Figure 1 which is a perspective structural view of the sleeve assembly device provided by the embodiment of the present utility model; Figure 2 which is a partial perspective structural view of the sleeve assembly device provided by the embodiment of the present utility model; Figure 3 is Figure 2Enlarged view of area A in []. The sleeve assembly device 1 of the present utility model includes a frame 11, a first positioning seat 12, a lifting assembly 13 and a clamping assembly 14. The first positioning seat 12 is installed on the frame 11, and a jack for inserting the first sleeve 2 is provided on the first positioning seat 12. The lifting assembly 13 includes a fixed frame 131, a movable frame 132 and a lifting driving member 133. The fixed frame 131 is fixed on the frame 11. The movable frame 132 is slidably connected to the fixed frame 131, and a second positioning seat 15 for inserting the second sleeve 3 is installed on the movable frame 132. The lifting driving member 133 is fixed on the fixed frame 131 and connected to the movable frame 132 to drive the movable frame 132 to lift and lower. The clamping assembly 14 is fixed on the frame 11 to clamp the first sleeve 2. The first positioning seat 12, the second positioning seat 15 and the clamping assembly 14 are coaxially arranged in the vertical direction.
[0024] When performing the sleeve assembly operation, first, an operator inserts the first sleeve 2 into the jack on the first positioning seat 12 and controls the clamping assembly 14 to clamp the first sleeve 2 to keep the position of the first sleeve 2 fixed. At this time, the operator takes the second sleeve 3 and inserts the top of the second sleeve 3 into the second positioning seat 15, so that the bottom of the second sleeve 3 is sleeved with the first sleeve 2. Subsequently, by controlling the lifting driving member 133 to drive the movable frame 132 to descend, the second sleeve 3 can be driven to descend under the pressing of the movable frame 132 and the second sleeve 3 is sleeved around the first sleeve 2 to achieve the assembly of the first sleeve 2 and the second sleeve 3.
[0025] Since the first positioning seat 12, the second positioning seat 15 and the clamping assembly 14 are coaxially arranged in the vertical direction, when assembling the first sleeve 2 and the second sleeve 3, the coaxiality of the first sleeve 2 and the second sleeve 3 can be ensured, so as to avoid the situation that the first sleeve 2 and the second sleeve 3 are not concentric, which may lead to defective or waste products in the assembled CDC shock absorber. Compared with the manual assembly method, the sleeve assembly device 1 of the present utility model can improve the efficiency of sleeve assembly and reduce the defective rate and waste rate of sleeve assembly at the same time.
[0026] In the embodiment of the present utility model, the first sleeve 2 is an intermediate cylinder, and the second sleeve 3 is a working cylinder, so that under the action of the lifting driving member 133, the working cylinder is extruded to descend and the working cylinder is sleeved around the intermediate cylinder. In other embodiments, the first sleeve 2 is a working cylinder, and the second sleeve 3 is an intermediate cylinder, so that under the action of the lifting driving member 133, the intermediate cylinder is extruded to descend and the intermediate cylinder is pressed into the working cylinder.
[0027] In an embodiment of the present utility model, the sleeve assembly device 1 further includes a pressure sensor 16, and the pressure sensor 16 is disposed between the second positioning seat 15 and the movable frame 132 to detect the pressure when the movable frame 132 presses the second sleeve 3.
[0028] The pressure sensor 16 is used to detect the pressure when the movable frame 132 descends and presses the second sleeve 3, so that the operator can judge whether there is a problem of edge cutting in the assembly of the first sleeve 2 and the second sleeve 3 according to the pressure detected by the pressure sensor 16. Furthermore, when there is an edge cutting problem, it is convenient for the operator to adjust the operation procedure of the sleeve assembly device 1 in time to avoid affecting the yield of batch sleeve assembly due to multiple edge cutting problems in continuous operation.
[0029] In an embodiment of the present utility model, the sleeve assembly device 1 further includes a curve screen 17, and the curve screen 17 is in signal connection with the pressure sensor 16 to display the pressure curve detected by the pressure sensor 16. Furthermore, it is convenient for the operator to judge whether there is an edge cutting problem in the assembly of the first sleeve 2 and the second sleeve 3 by observing the pressure curve on the curve screen 17. That is, when the pressure curve is a smooth curve, there is no edge cutting problem in the assembly of the first sleeve 2 and the second sleeve 3. When the pressure curve jumps, there is an edge cutting problem in the assembly of the first sleeve 2 and the second sleeve 3. Furthermore, when there is an edge cutting problem, it is convenient for the operator to adjust the operation procedure of the sleeve assembly device 1 in time to avoid affecting the yield of batch sleeve assembly due to multiple edge cutting problems in continuous operation.
[0030] Please refer to Figure 3 In an embodiment of the present utility model, the clamping assembly 14 includes a clamping base 141, a clamping driving member 142 and clamping jaws 143. The clamping base 141 is fixed on the frame 11 for the clamping driving member 142 to be installed. The clamping jaws 143 are symmetrically installed on the left and right sides of the clamping driving member 142 for the clamping driving member 142 to drive the two clamping jaws 143 to approach or move away from each other simultaneously.
[0031] The clamping base 141 provides support for the clamping driving member 142 to make the position of the clamping driving member 142 close to the top of the first sleeve 2. After the clamping driving member 142 drives the clamping jaws 143 to clamp the first sleeve 2, the position of the first sleeve 2 can be fixed. Cooperating with the insertion fit between the bottom of the first sleeve 2 and the first positioning seat 12, the first sleeve 2 can be prevented from tilting in the vertical direction. Furthermore, when the lifting driving member 133 drives the movable frame 132 to squeeze the second sleeve 3, the second sleeve 3 can be inserted into the first sleeve 2 in the vertical direction to improve the yield of sleeve assembly and avoid the problems of defective products and waste caused by the non-concentricity of the first sleeve 2 and the second sleeve 3.
[0032] When the driving member drives the two jaws 143 to approach simultaneously, the two jaws 143 can jointly clamp the first sleeve 2. At this time, it is convenient to perform the sleeve assembly operation. The second cylinder can be sleeved on the first sleeve 2. When the driving member drives the jaws 143 to move away simultaneously, the two jaws 143 can release the first sleeve 2, so that the operator can take out the assembled first sleeve 2 and second sleeve 3 to perform the operation of the next process.
[0033] In an embodiment of the present invention, the lifting driving member 133 further includes any one of a cylinder, an electric cylinder, and a hydraulic cylinder, so as to drive the movable frame 132 to lift under the drive of the lifting driving member 133, and squeeze the second sleeve 3 and the first sleeve 2 for sleeving during the process of the movable frame 132 descending, thereby realizing the sleeve assembly operation of the first sleeve 2 and the second sleeve 3.
[0034] In another embodiment of the present invention, the lifting assembly 13 further includes a lead screw 134 and a sliding nut. The lifting driving member 133 is a motor. One end of the lead screw 134 is connected to the lifting driving member 133, and the other end is rotatably connected to the frame 11. The sliding nut is installed on the movable frame 132 and is threadedly connected to the lead screw 134.
[0035] By connecting the two ends of the lead screw 134 to the lifting driving member 133 and the frame 11 respectively, the lead screw 134 is driven to rotate under the drive of the lifting driving member 133. By installing the sliding nut on the movable frame 132, the lead screw 134 can pass through the sliding nut, and when the lead screw 134 rotates, the sliding nut together with the movable frame 132 is driven to lift synchronously, so that the movable frame 132 slides on the fixed frame 131. By controlling the forward and reverse rotation of the lifting driving member 133, the rising and falling of the movable frame 132 are controlled. When the movable frame 132 descends, the movable frame 132 can squeeze the second sleeve 3 and the first sleeve 2 for sleeving, thereby realizing the sleeve assembly operation of the first sleeve 2 and the second sleeve 3.
[0036] Please refer to Figure 2 , in an embodiment of the present invention, the sleeve assembly device 1 further includes an opposed photoelectric sensor 18. The opposed photoelectric sensor 18 is installed on the frame 11 on both sides of the first positioning seat 12 to detect the first sleeve 2 on the first positioning seat 12. The opposed photoelectric sensor 18 is signal-connected to the clamping assembly 14 to control the clamping assembly 14 to clamp the first sleeve 2.
[0037] By signal - connecting the opposed - type photoelectric sensor 18 with the clamping assembly 14, when the opposed - type photoelectric sensor 18 detects that the first sleeve 2 is placed on the first positioning seat 12, the opposed - type photoelectric sensor 18 controls the clamping assembly 14 to clamp the first sleeve 2. Then, it is convenient for the operator to place the second sleeve 3 between the first sleeve 2 and the movable frame 132. When the lifting drive member 133 drives the movable frame 132 to descend, the second sleeve 3 is extruded and fitted onto the first sleeve 2. The action of the clamping assembly 14 clamping the first sleeve 2 is automatically controlled by the opposed - type photoelectric sensor 18, which can further improve the assembly efficiency of the sleeve assembly.
[0038] In the embodiment of the present invention, when the first sleeve 2 is placed on the first positioning seat 12, the first sleeve 2 can block the light beam emitted by the opposed - type photoelectric sensor 18. Then, it can be detected that the first sleeve 2 is placed on the first positioning seat 12. On the contrary, when the first sleeve 2 is not placed on the first positioning seat 12, the light beam emitted by the opposed - type photoelectric sensor 18 can be received by the opposed - type photoelectric sensor 18 on the other side. At this time, it can be detected that the first sleeve 2 is not placed on the first positioning seat 12.
[0039] In the embodiment of the present invention, the sleeve assembly device 1 further includes a detection bracket. The detection bracket is installed on the frame 11 on both sides of the first positioning seat 12, and the opposed - type photoelectric sensor 18 is slidably installed on the detection bracket.
[0040] By slidably installing the opposed - type photoelectric sensor 18 on the detection bracket, it is convenient to adjust the height position of the opposed - type photoelectric sensor 18. Then, the opposed - type photoelectric sensor 18 can detect the first sleeve 2 at different heights to adapt to the detection operation of first sleeves 2 with different lengths. Then, according to the detection result, the clamping assembly 14 is controlled to automatically clamp the first sleeve 2, improving the sleeve assembly efficiency.
[0041] To avoid the problem that the second sleeve 3 cannot be completely fitted onto the first sleeve 2 when the clamping assembly 14 clamps the first sleeve 2, when the lifting drive member 133 drives the movable frame 132 to descend to a preset position, the clamping assembly 14 can be controlled to release the first sleeve 2. Then, the lifting drive member 133 is continuously controlled to drive the movable frame 132 to descend until the bottom of the second sleeve 3 is in contact with the surface of the first positioning seat 12, so as to realize the assembly operation of the first sleeve 2 and the second sleeve 3.
[0042] In the embodiment of the present invention, the sleeve assembly device 1 further includes a proximity switch 10. The proximity switch 10 is installed on the fixed frame 131 to detect the position of the movable frame 132, and the proximity switch 10 is signal - connected with the clamping assembly 14 to control the clamping assembly 14 to release the first sleeve 2.
[0043] The position of the movable frame 132 is detected by the proximity switch 10, and the proximity switch 10 is signal-connected to the clamping assembly 14, so that when the proximity switch 10 detects that the movable frame 132 reaches the preset position, the proximity switch 10 is triggered to release the first sleeve 2, so that the lifting drive member 133 drives the movable frame 132 to descend and the bottom of the second sleeve 3 fits against the surface of the first positioning seat 12. The action of the clamping assembly 14 releasing the first sleeve 2 is automatically controlled by the proximity switch 10, which can further improve the assembly efficiency of the sleeve assembly.
[0044] In an embodiment of the present utility model, the sleeve assembly device 1 further includes a protective plate 19 and a protective door. The protective plate 19 and the protective door are jointly disposed around the lifting assembly 13 on the frame 11, and the protective door is hingedly connected to the frame 11.
[0045] By jointly disposing the protective door and the protective plate 19 around the frame 11, the protective effect on the operator during the sleeve assembly operation can be achieved. When material splashing occurs when the first sleeve 2 and the second sleeve 3 are not concentric, the protective door and the protective plate 19 provide protection for the operator, improving the operation safety of the operator.
[0046] By hingedly connecting the protective door to the frame 11, it is convenient for the operator to open or close the protective door, so as to perform the operations of loading and unloading when the protective door is open, and perform the sleeve assembly operation when the protective door is closed, improving the safety of the operator.

[0048] In the present utility model, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath", and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.
