[0014] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0015] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0017] like Figures 1 to 3As shown, an automatic oiling and greasing machine for oil seals for shock absorbers includes a frame 1, an oiling mechanism 2 and a workpiece clamping mechanism 3. The frame 1 has a built-in machine table 11, and the oiling mechanism 2 and the workpiece clamping mechanism 3 are installed side by side on the machine table 11. The oiling mechanism 2 includes a greasing machine 21, a grease box 22 and a channel pipe 23. The greasing machine 21 is connected to the grease box 22 through the channel pipe 23. The upper end of the grease box 22 is open. The workpiece clamping mechanism 3 includes a positioning bracket 31, a rotary clamping member 32, The rotary motor 33, the positioning bracket 31 and the rotary clamping member 32 cooperate to press the workpiece 100, and the positioning bracket 31 and the rotary clamping member 32 are provided with ball bearings at the contact points with the workpiece 100. The output end of the rotary motor 33 is provided with a magnetic block, and the magnetic block is magnetically connected to the rear end of the workpiece 100. The rotary motor 33 drives the workpiece 100 to rotate between the positioning bracket 31 and the rotary clamping member 32 through the magnetic block, and the front end of the workpiece 100 abuts against the end of the grease box 22. Specifically, in this embodiment, the frame 1 is in the shape of a square frame, and has a built-in machine platform 11, which is used to support the oiling mechanism 2 and the workpiece clamping mechanism 3. The workpiece clamping mechanism 3 includes a positioning bracket 31, a rotary clamping member 32, and a rotary motor 33. During operation, the staff places the workpiece 100 on the positioning bracket 31, and then presses the rotary clamping member 32 downward to cooperate with the positioning bracket 31 to clamp the workpiece 100 to prevent the workpiece 100 from being unevenly oiled and misaligned. The grease injection machine 21 is connected to the grease box 22 through the channel tube 23. After the grease box 22 is filled with grease, in order to evenly apply grease to the front end surface of the workpiece 100 and avoid rotating the grease box and throwing away the grease, we apply oil by rotating the workpiece 100. The workpiece 100 is movably connected to the positioning bracket 31 and the rotary clamping member 32, specifically through ball or roller abutment. The end of the rotary motor 33 is provided with a magnetic block for magnetically connecting with the rear end of the workpiece 100. When the rotary motor 33 is started, it can drive the workpiece 100 to rotate. It can complete the oiling operation by rotating one circle in the grease box 22.

[0018] like Figure 2 As shown, arc notches 221 are provided at both ends of the grease box 22 , and the front end of the workpiece 100 is movably engaged at the arc notches 221 . The arc notches 221 play a limiting role to prevent the front end of the workpiece 100 from deflecting.

[0019] Specifically, a valve is provided on the channel tube 23, and the valve is a one-way valve, so that the grease can only flow downstream through the channel tube 23 and be injected into the grease box 22 from the grease injection machine 21 to avoid backflow.

[0020] like Figure 1 As shown, the frame 1 is also provided with a controller 12, and the controller 12 is controlled by a touch screen, so that the operator can adjust parameters according to the actual model and size of the workpiece 100, which is more convenient to use.

[0021] like Figure 3 As shown, the rotary clamping member 32 includes a clamping cylinder 321 and a clamping rod 322. The output end of the clamping cylinder 321 is connected to the clamping rod 322 to drive the clamping rod 322 to rise and fall. Specifically, when the clamping cylinder 321 drives the clamping rod 322 to move upward, the clamping rod 322 is separated from the positioning bracket 31, which is convenient for the operator to replace the oiled workpiece 100. After the replacement is completed, the clamping cylinder 321 drives the clamping rod 322 to reset, so that it cooperates with the positioning bracket 31 and re-presses the workpiece 100 to avoid radial vibration of the workpiece during application, resulting in poor contact between the front end and the grease box 22, resulting in uneven application.

[0022] Specifically, the frame 1 is formed by splicing aluminum alloy profiles, has high structural strength and is light in weight, and is easy to carry and move in a workshop.

[0023] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
