[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 3 As shown, the automatic retrieving device for special pump oil seals described in Example 1 includes a bracket 1, on which are provided a discharge tray 2 and a sheath storage mechanism 11, which are arranged side by side and cooperate with each other. The discharge tray 2 is used to store oil seals 14; the sheath storage mechanism 11 is used to store sheaths 9. The bracket 1 is provided with a movable and liftable retrieving mechanism for clamping the oil seal 14 from the discharge tray 2 and fitting it onto the sheath 9 on the sheath storage mechanism 11. The discharge tray 2 is provided with a plurality of oil seal discharge countersinks 21, in which the oil seals can be stored and positioned by the oil seal discharge countersinks 21, making it easier for the retrieving mechanism to grasp the oil seals. The discharge tray 2 is rotatably mounted on the bracket 1, and a drive motor is provided on the bracket 1 to drive the rotation of the discharge tray 2, thereby facilitating the sequential rotation of the oil seal discharge countersinks 21 containing the oil seals 14 to a position convenient for the retrieving mechanism to grasp. The sheath storage mechanism 11 is movably inserted with the sheath 9.

[0024] like Figure 5 As shown, the upper end of the sleeve 9 is conical, which is convenient for the oil seal 14 to be inserted. A clamping groove is left on the neck for easy clamping to ensure that the sleeve 9 will not fall off when taking and placing. The internal through hole of the sleeve 9 is convenient for the oil seal to be inserted into the gear shaft during assembly to protect the oil seal from being damaged.

[0025] The retrieving mechanism further comprises a movable plate 12 that is movably mounted on the support 1, an air gripper 7 that is lifted and connected to the movable plate 12, and two clamping blocks 8 connected to the working ends of the air gripper 7. The two clamping blocks 8 are symmetrically arranged to open and close. The air gripper 7 is connected to the movable plate 12 via a lifting cylinder 6. The movable plate 12 is connected to the support 1 via a movable drive mechanism.

[0026] Example 2 is different from Example 1 in that Figure 2 and Figure 3 As shown, the two clamping blocks 8 are each provided with an oil seal clamping portion 81 for clamping the oil seal 14 and a sheath clamping portion 82 for clamping the sheath 9 .

[0027] Specifically, if Figure 4As shown, the oil seal clamping portion 81 is a circular arc-shaped groove provided on the clamping block 8. This groove conforms to the outer shape of one side of the oil seal, allowing the two symmetrically arranged clamping blocks 8 to clamp both sides of the oil seal 14. The axis of the circular arc-shaped groove is vertically oriented. A fan-shaped baffle 83 is provided at the top of the arc-shaped groove, with a circular arc-shaped notch at the top corner of the fan-shaped baffle. This arc-shaped notch prevents the fan-shaped baffle 83 from interfering with the sheath 9. A stopper 84 is provided on the clamping block 8, located on one side of the fan-shaped baffle 83 and cooperating with it. A V-shaped sheath clamping portion 82 is formed between the side edges of the fan-shaped baffle 83 and the stopper 84, allowing the two symmetrically arranged clamping blocks 8 to easily clamp onto the clamping groove of the sheath 9, thereby stably retaining the sheath 9. Furthermore, the fan-shaped baffle 83 is of a certain length, ensuring that the sheath clamping portion and the oil seal clamping portion are offset by a certain gap to prevent interference.

[0028] Example 3 is different from Example 1 in that Figure 1 As shown, the sheath storage mechanism 11 is provided with an oil tank 111 for storing oil, and the oil tank 111 is located on the side of the sheath storage mechanism 11 close to the discharge tray 2, so that the material taking mechanism can immerse the oil seal 14 in oil in the oil tank 111 after clamping the oil seal 14, and then put the oil seal 14 on the sheath 9.

[0029] Example 4 is different from Example 1 in that Figure 2 As shown, a pressing mechanism is provided on the movable plate 12. The pressing mechanism is provided on one side of the material taking mechanism. After the material taking mechanism assembles the oil seal 14 and the sleeve 9, the assembled oil seal 14 and the sleeve 9 are clamped and moved to the top of the product to be assembled, i.e., the special pump. The assembled oil seal 14 and the sleeve 9 are pressed into the special pump by the pressing mechanism.

[0030] Specifically, the pressing mechanism includes a pressing head 15 and a pressing driving member 13 for driving the pressing head 15 to move up and down. The pressing driving member 13 is a pneumatic cylinder, an electric push rod or an oil cylinder.

[0031] Example 5 is different from Example 1 in that Figure 2 As shown, photoelectric sensing mechanisms 10 are provided on both sides of the sheath storage mechanism 11 for sensing whether the oil seal 14 and the sheath 9 are assembled in place.

[0032] Example 6 is different from Example 1 in that Figure 2As shown, the movable drive mechanism comprises a screw 4 rotatably mounted on a bracket 1, a drive motor 3 that drives the screw 4, and a screw block threadedly connected to the screw 4. The screw 4 is positioned along the direction of movement of the reclaiming mechanism. The screw block is fixedly connected to the movable plate 12. The rotation of the screw 4 drives the movable plate 12, thereby driving the reclaiming mechanism. A matching slide rail 5 and slider are provided between the bracket 1 and the movable plate 12 to limit the movement of the movable plate 12.

[0033] In addition, the device is also equipped with a PLC controller connected to various driving mechanisms as well as motors, air grippers, etc.

[0034] When the device is in use, under the control of the PLC, the clamping block 8 and the lifting cylinder 6 of the feeding mechanism will stop above the oil seal feeding position, and the lifting cylinder 6 will move downward, thereby driving the clamping block 8 to the oil seal and clamping the oil seal, and then the lifting cylinder 6 will move in the opposite direction, and the oil seal clamped by the clamping block 8 will be separated from the discharge tray 2, and then the PLC controls the feeding mechanism to immerse the oil in the oil tank 11, and after immersion in oil, the oil seal will be passed onto the sheath 9. The photoelectric sensing mechanism 10 is used to sense whether the assembly is in place. After the assembly is completed, the feeding mechanism will send the oil seal and the sheath to the pressing position above the product to be assembled, and the pressing drive 13 will press down, and the pressure head 15 installed thereon will press the oil seal into the product.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
