[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figure 1 , Figure 2 The figure shows a specific embodiment of the piston rod rotating groove oiling device (hereinafter referred to as the oiling device) provided by the utility model, which is used to automatically oil the rotating groove of the piston rod, wherein the rotating groove of the piston rod includes a partially straight groove body extending along the axial direction and an arc-shaped groove body located at one end of the straight groove body.

[0027] The oiling device includes a supporting body 10 for supporting a piston rod A to be oiled, and the supporting body 10 can rotate under the drive of a rotary drive unit 20; a rotary pressure head 30 that cooperates with the supporting body 10 to enable the piston rod A to be oiled to rotate reliably, and the rotary pressure head 30 moves along a first direction under the action of a first linear drive unit 31 to press the piston rod A to be oiled. When working, one end of the piston rod A to be oiled is fixedly connected to the supporting body 10, and the other end is rotatably connected to the supporting groove of the rotary pressure head 30, and can rotate with the supporting body 10. When it rotates to a set position, the oiling operation of the rotating groove of the piston rod A to be oiled is realized.

[0028] The oiling device includes a clamping oiling portion 40, which includes a first clamping portion 40a and a second clamping portion 40b located on both sides of a piston rod A to be oiled, and the first clamping portion 40a and the second clamping portion 40b move in a straight line under the action of a clamping driving portion 41 to clamp the piston rod A to be oiled, and an oiling channel is provided on the first clamping portion 40a; an oiling pipeline 44, which is slidably connected to the oiling channel of the first clamping portion 40a, and the oiling pipeline 44 extends from the inner side of the first clamping portion 40a to the rotating groove of the piston rod A to be oiled under the action of an oiling driving portion 46, and the oiling pipeline 44 is connected to a lubricating oil supply pump, and the oiling operation of the piston rod A to be oiled is realized by controlling the opening and closing of the lubricating oil supply pump.

[0029] When the above-mentioned oiling device is used to oil the piston rod A to be oiled, the piston rod A to be oiled is first fixed on the supporting body 10, the rotary pressure head 30 is controlled to press against the upper side of the piston rod A to be oiled, the rotary drive part 20 is controlled to be turned on, and the piston rod A to be oiled is rotated to the set position, and the clamping drive part 41 is controlled to clamp the rod body of the piston rod A to be oiled with the first clamping part 40a and the second clamping part 40b, and then the oiling drive part 46 is controlled to make the oiling pipeline 44 extend into the rotating groove of the piston rod A to be oiled, and the lubricating oil supply pump is controlled to be turned on, and the lubricating oil flows from the oiling pipeline 44 into the rotating groove of the piston rod A to be oiled, thereby realizing the automatic oiling operation of the piston rod A to be oiled.

[0030] Specifically, in an optional implementation manner, Figure 3 , Figure 4 The first clamping part 40a and the second clamping part 40b respectively include a support seat body 42 and a clamping body 43 detachably connected to the support seat body 42. Specifically, the support seat body 42 is provided with a plug-in slot, and the clamping body 43 is plugged into the plug-in slot of the support seat body 42 and the two are fixedly connected by a positioning pin 45. The clamping body 43 is provided with a semicircular groove matching the size of the piston rod A to be oiled, and the two clamping parts move synchronously toward the rod body direction of the piston rod A to be oiled to achieve the clamping operation of the piston rod A to be oiled. By setting the clamping part as a split detachable structure, by replacing the clamping body 43, it is convenient to clamp piston rods with different rod diameters.

[0031] Specifically, in an optional embodiment, the clamping driving part 41 is a second cylinder installed on the sliding seat 50, and the second cylinder is a double piston rod cylinder, and the two cylinder rods extend or retract in opposite directions. One of the piston rods acts on the support seat body 42 of the first clamping part 40a, and the other piston rod acts on the support seat body 42 of the second clamping part 40b. When the piston rod of the second cylinder is synchronously extended, the first clamping part 40a and the second clamping part 40b are in the unlocking position, and when the piston rod of the second cylinder is synchronously retracted, the first clamping part 40a and the second clamping part 40b are in the clamping position, so as to clamp the piston rod A to be oiled.

[0032] Specifically, in an optional implementation manner, Figure 4 As shown, the support seat body 42 of the first clamping part 40a and the clamping body 43 are respectively provided with oiling channels, and the oiling pipeline 44 includes a first oil pipe 441 arranged in the oiling channel of the support seat body 42 and a second oil pipe 442 arranged in the oiling channel of the clamping body 43, and the second oil pipe 442 pushes the first oil pipe 441 under the action of the oiling drive part 46 to make it extend out of the clamping body 43.

[0033] The oiling drive unit 46 is a first cylinder installed on the support seat body 42, and the second oil pipe 442 is fixedly connected to the oil pipe support block 47 in a partial area outside the support seat body 42, and the piston rod of the first cylinder acts on the oil pipe support block 47 to drive the second oil pipe 442 to slide relative to the support seat body 42. Specifically, when the piston rod of the first cylinder is extended, the second oil pipe 442 moves relative to the support seat body 42 in a direction away from the first oil pipe 441, and when the piston rod of the first cylinder is retracted, the second oil pipe 442 moves relative to the support seat body 42 in a direction close to the first oil pipe 441 until it pushes against the first oil pipe 441 to the outside of the clamping body 43.

[0034] Specifically, in order to keep the first oil pipe 441 on the inner side of the clamping body 43 in the initial state, so as to realize the reliable clamping of the piston rod A to be oiled by the first clamping part 40a and the second clamping part 40b, a reset member 48 is provided between the first oil pipe 441 and the clamping body 43, and the reset member 48 can be selected as a compression spring; in the initial state, the first oil pipe 441 is located as a whole on the inner side of the clamping body 43 under the action of the reset member 48; in the working state (i.e., the oiling state), the second oil pipe 442 overcomes the action of the reset member 48 and pushes against the first oil pipe 441 so that a part of its area extends out of the clamping body 43.

[0035] When the oiling operation of the piston rod A to be oiled is completed, the oiling pipeline 44 needs to be closed to block the oil supply. The oil pipe support block 47 is provided with a mounting hole connected to the oiling pipeline 44. The oil pipe support block 47 is provided with a control valve block 49. The control valve block 49 has a retractable valve stem 491. The valve stem 491 can be extended into the first oil pipe 441 along the mounting hole to block the fluid in the first oil pipe 441.

[0036] Since the rotating groove of the piston rod A to be oiled extends a certain distance along the axial direction, in order to make the lubricating oil coating more uniform in different areas of the rotating groove, the oil coating device also includes a second linear driving part 60 that drives the clamping and oiling part 40 to move along the first direction, and the output end of the second linear driving part 60 acts on the sliding seat 50, and the clamping driving part 41 is fixed on the sliding seat 50. The second linear driving part 60 drives the sliding seat 50 to move linearly, thereby driving the clamping and oiling part 40 to clamp on the piston rod A to be oiled, so as to realize the clamping and oiling operation along the axial direction. More specifically, the second linear driving part 60 is a linear electric cylinder.

[0037] In order to make the piston rod A to be oiled reliably rotate to the set oiling position, the oiling device also includes a position detection device 70 and a control unit. The position detection device 70 includes a transmitting end and a receiving end. The transmitting end of the position detection device 70 transmits a light signal toward the piston rod. The control unit determines whether the piston rod A to be oiled rotates to the set position according to the feedback signal of the receiving end of the position detection device 70. When the piston rod A to be oiled rotates with the support body 10, when it rotates to the first set position, the rotation groove of the piston rod A to be oiled is directly opposite to the transmitting end and the receiving end of the position detection device 70. Since the distance of the bottom of the rotation groove relative to the position detection device 70 is different from the distance of other positions of the oiling piston rod relative to the position detection device 70, the feedback signal of the output end of the position detection device 70 changes, and the control unit determines whether the piston rod A to be oiled rotates to the set position according to the feedback signal.

[0038] Specifically, in an optional embodiment, the rotary drive unit 20 is a rotary electric cylinder, and the rotary drive unit 20 is installed on a sliding platform 80. The sliding platform 80 moves along the second direction under the action of a third linear drive unit 90. The third linear drive unit 90 is a third air cylinder. The piston rod of the third air cylinder is extended or retracted to control the switching of the sliding platform 80 between the first working position and the second working position.

[0039] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present utility model.
