[0010] The bed is also provided with a counting system for detecting the number of piston rings on the column.

[0011] The second object of the present invention is to provide an operating method of a special machine tool for CNC milling and slicing of piston rings, and the specific operating method includes the following steps:

[0012] S1. Identify the number of piston rings on the column by the counting system, and according to the identification result, add or reduce piston rings so that the number of piston rings on the column meets the standard requirement;

[0013] S2, the telescopic cylinder contracts, the telescopic rod moves backward, driving the elastic clamping plate to approach the column and away from the wedge plate, so that the elastic clamping plate clamps the piston ring on the column, at this time the movable inclined plate is inactive, and the connecting rope is loose;

The bottom support plate 6 and the movable inclined plate 4 are both used to support and sleeve the piston ring on the column 3. The bottom of the column 3 is provided with a pressure cone 7 that moves longitudinally in the accommodation space. The pressure cone 7 is wide at the top and narrow at the bottom, and is sandwiched between the movable inclined plate 4 and the bottom support plate 6. The movable inclined plate 4 can be moved away from the bottom support plate 6 by the movable member to release the restriction on the piston ring on the column 3, and the pressure cone 7 and the column 3 can move downward;

[0039] An elastic clamping plate 5, a telescopic rod 9 and a buffer connected to the telescopic rod 9 are also provided above the base plate 2. The top of the telescopic rod 9 is rotatably connected to the elastic clamping plate 5. A connecting rope 8 for pulling the movable inclined plate 4 is provided between the telescopic rod 9 and the movable inclined plate 4. The buffer is used to firstly enable the elastic clamping plate 5 to clamp the piston ring on the column 3 when the movable inclined plate 4 is away from the bottom supporting plate 6, and then enable the elastic clamping plate 5 to move upward while the pressing cone 7 and the column 3 move downward.

[0040] The bed 1 is also provided with a counting system for detecting the number of piston rings on the column 3 .

[0041] Furthermore, the elastic clamping plate 5 includes two clamping arms hinged to each other at the front, and the hinge axis of the clamping arm is rotatably connected to the top of the telescopic rod 9.

[0042] The movable part includes two sliding plates 10 respectively arranged on the left and right sides of the pressing cone 7. The rear end of the sliding plate 10 is connected and fixed to the movable inclined plate 4. The bottom support plate 6 is provided with a sliding groove 11 that slides with the sliding plate 10. The bottom support plate 6 is also provided with a movable plug rod that is rotatably connected to the base plate 2. When the sliding plate 10 slides in the sliding groove 11, the bottom support plate 6 is adaptively rotated through the movable plug rod.

[0043] It should be noted that when the bottom support plate 6 is adaptively rotated by the movable plug rod, the bottom support plate 6 is no longer in contact with the outer wall surface of the pressing cone 7, and the downward movement of the pressing cone 7 is not affected.

[0044] In some embodiments, the bottom support plate 6 includes two bottom support units spaced apart from each other, the sliding groove 11 is arranged on the bottom support unit at a position corresponding to the sliding plate 10, and the movable insertion rod is correspondingly arranged on the left side of the left bottom support unit and the right side of the right bottom support unit, so that the sliding plate 10 slides more smoothly in the sliding groove 11.

[0045] A tension spring 12 and a telescopic limiting rod 13 for resetting the pressing cone 7 are provided between the base plate 2 and the pressing cone 7 .

[0046] The buffer member includes a power member and a connecting rod 14 for driving the telescopic rod 9 to move forward and backward. One end of the connecting rod 14 is connected and fixed to the top of the telescopic rod 9.

A wedge plate 15 that presses against the elastic clamping plate 5 is fixedly connected to the base plate 2. The telescopic rod 9 is provided with a lifting member that drives the telescopic rod 9 to move upward.

[0047] The power member drives the telescopic rod 9 to move forward and backward, and a through slot corresponding to the telescopic rod 9 is provided on the base plate 2 to allow the telescopic rod 9 to move forward and backward.

[0048] When the telescopic rod 9 moves backward, the connecting rod 14 drives the elastic clamping plate 5 to move and approach the piston ring, and the moving elastic clamping plate 5 gradually moves away from the wedge plate 15. At this time, the wedge plate 15 is released from the pressure on the elastic clamping plate 5. Under the reset elastic action of the torsion spring rod 25, the elastic clamping plate 5 rotates with the torsion spring rod 25 as the rotating axis (that is, the front ends of the two clamping arms rotate toward the wedge plate 15, and the angle between the rear ends of the two clamping arms gradually decreases, so that the elastic clamping plate 5 clamps the movable ring);

[0049] The power member includes a telescopic cylinder 16 connected and fixed in the accommodating space, the telescopic end of the telescopic cylinder 16 is fixedly connected to a U-shaped plate 17, the movable inclined plate 4 is fixedly connected to a sleeve 18 sleeved with the U-shaped plate 17, and the U-shaped plate 17 is connected and fixed to the telescopic rod 9.

[0050] Furthermore, one end of the connecting rope 8 is connected to the movable inclined plate 4 , and the other end of the connecting rope 8 is connected to the U-shaped plate 17 .

[0051] The lifting member includes a first connecting rod 19 connected and fixed to the base plate 2, a second connecting rod 20 is penetrated through the telescopic rod 9, and an obliquely arranged sliding rod 21 is also provided between the first connecting rod 19 and the second connecting rod 20, the top end of the sliding rod 21 is connected to the first connecting rod 19, and the bottom end of the sliding rod 21 is connected to the second connecting rod 20, and the thickness of the sliding rod 21 is smaller than the first connecting rod 19 and the second connecting rod 20, and a matching member is provided on the top of the pressure cone 7 for cooperating with the telescopic rod 9 when lifting.

[0052] The mating piece includes a mating plate 22 connected and fixed to the bottom of the column 3 , a mating groove 23 slidably mated with the mating plate 22 is formed on the top surface of the pressing cone 7 , and a compression spring 24 connected to the mating plate 22 is hung in the mating groove 23 .

[0053] The counting system includes a fixed rod 26 connected to the movable inclined plate 4, and a paddle plate 27 cooperating with a piston ring is rotatably connected to the fixed rod 26. An elastic compression member 28 is provided between the fixed rod 26 and the paddle plate 27. A pressing plate 29 is provided on the paddle plate 27. A pot piece 30 is provided on the fixed rod 26 to press and cooperate with the pressing plate 29, and the pot piece 30 cooperates with the background computing platform signal.

[0054] An operating method of a special machine tool for CNC milling and slicing of piston rings, using the above-mentioned special machine tool for CNC milling and slicing of piston rings, the specific operating method includes the following steps;

[0055] S1. Identify the number of piston rings on the column 3 by the counting system (the piston rings are inserted into the column 3 by the feeding system, which is a common technology on machine tools and will not be described in detail), and according to the identification result, add or reduce the piston rings (add by the external first manipulator) so that the number of piston rings on the column 3 meets the standard requirements;

[0056] S2, the telescopic cylinder 16 contracts, the telescopic rod 9 moves backward, driving the elastic clamping plate 5 to approach the column 3 and away from the wedge plate 15, so that the elastic clamping plate 5 clamps the piston ring on the column 3, at this time the movable inclined plate 4 is inactive, and the connecting rope 8 is loose;

[0057] S3, the telescopic cylinder 16 continues to contract, driving the connecting rope 8 from being relaxed to being stretched straight, and at this time the telescopic rod 9 is close to the bottom end of the sliding rod 21;

[0058] S4, the telescopic cylinder 16 continues to contract, the movable inclined plate 4 moves away from the bottom supporting plate 6, the telescopic rod 9 moves backward along the slide rod 21 and stretches adaptively, thereby driving the elastic clamping plate 5 clamping the piston ring to move upward, and the column 3 moves along the direction of the matching groove 23. At the same time, the column 3 moves downward with the pressing cone 7 under the action of the tension spring 12, thereby causing the elastic clamping plate 5 clamping the piston ring to be separated from the column 3;

[0059] S5, opening the elastic clamping plate 5 (through an external second manipulator), and transferring the piston rings whose quantity reaches the standard requirement to the packaging process.

[0060] When the piston rings are inserted into the pillar 3 one by one, the piston rings fall downward after contacting the paddle plate 27. Under the action of the elastic compression member 28, the paddle plate 27 is rotated and reset, that is, it reciprocates at a certain angle, so that the pressing plate 29 presses the pot piece 30 once. Each time the pot piece 30 is pressed, it is recorded by the background calculation platform, thereby realizing the function of counting the number of piston rings inserted on the pillar 3;

[0061] It is worth noting that when the movable inclined plate 4 moves backward with the telescopic cylinder 16, the paddle plate 27 moves synchronously away from the piston ring to avoid the paddle plate 27 causing obstruction when the elastic clamping plate 5 drives the piston ring to move upward.

[0062] Among the piston rings inserted into the column 3, the piston ring at the bottom is in pressure contact with the movable inclined plate 4, the bottom supporting plate 6, the sliding plate 10 and the top surface of the pressing cone 7 at the same time;

[0063] Under the action of the power member, the movable inclined plate 4 slides backward and drives the two sliding plates 10 to move. Under the action of the sliding groove 11, the movable inclined plate 4 is moved away from the bottom supporting plate 6. In this way, the movable inclined plate 4, the bottom supporting plate 6 and the sliding plate 10 are separated from the bottom supporting effect on the bottom of the piston ring.

[0064] On the other hand, since the movable inclined plate 4 is away from the bottom support plate 6 and the restriction on the pressure cone 7 is released, the pressure cone 7 drives the column 3 to move downward under the action of the gravity of the pressure cone 7 and the column 3 and the tension of the tension spring 12, which, in conjunction with the lifting piece, is more conducive to the piston ring to separate from the column 3.

[0065] The tension spring 12 allows the pressure cone 7 to keep moving vertically downward, and cooperates with the downward gravity effect of the column 3 and the pressure cone 7 to help the vertical downward movement of the column 3. The telescopic limit rod 13 is preferably an electric push rod, and the output end of the electric push rod is fixedly connected to the bottom of the pressure cone 7. When the pressure cone 7 needs to be reset, the electric push rod is driven by the power transmission device provided in the machine tool, and pushes the pressure cone 7 to move upward.

[0066] The working principle of the special machine tool for piston ring numerical control milling and slicing of the present invention is roughly as follows:

[0067] By starting the telescopic cylinder 16, the telescopic cylinder 16 is contracted, driving the U-shaped plate 17 to move closer to the telescopic cylinder 16;

[0068] The U-shaped plate 17 moves, first driving the telescopic rod 9 to move backward, so that the elastic clamping plate 5 moves close to the piston ring and clamps the piston ring. At this time, the connecting rope 8 is gradually straightened from the relaxed state, the movable inclined plate 4 is still inactive at this time, and the column 3 remains in place;

[0069] The U-shaped plate 17 continues to move, and then the connecting rope 8 is straightened, and at the same time the telescopic rod 9 contacts the sliding rod 21;

[0070] The U-shaped plate 17 continues to move, and then the elastic clamping plate 5 holding the piston ring moves upward at an angle, and the movable inclined plate 4 also moves towards the telescopic cylinder 16, so that the movable inclined plate 4 is away from the bottom supporting plate 6 and the column 3 moves downward, that is, the piston ring is moved upward by the lifting member and moved downward by the column 3, and the piston ring is separated from the column 3 by two-way cooperation.

[0071] The telescopic rod 9, under the action of the second connecting rod 20 in the lifting member, drives the elastic clamping plate 5 to move horizontally, thereby clamping the piston ring on the column 3;

[0072] When the elastic clamping plate 5 holding the piston ring moves on the inclined slide bar 21, the telescopic cylinder 16 continues to drive the telescopic rod 9 to move horizontally, and under the guidance of the slide bar 21, drives the telescopic rod 9 to extend upward, so that the elastic clamping plate 5 holding the piston ring moves obliquely upward through the connecting rod 14, and the piston ring is separated from the column 3 through the action of the matching piece, so that the piston rings that meet the standard quantity can be transferred to the packaging process later;

[0073] The thickness of the slide bar 21 is relatively small, so as to ensure that the slide bar 21 slides with the through hole of the telescopic rod 9, and the through hole is used for sliding with the first connecting rod 19, the second connecting rod 20 and the slide bar 21;

[0074] Furthermore, the telescopic rod 9 is provided with two sets of guide wheels at the through hole through which the second connecting rod 20 is passed. The two sets of guide wheels are respectively arranged on the upper and lower sides of the inner wall of the hole, and cooperate with the first connecting rod 19, the second connecting rod 20 and the sliding rod 21 to reduce the friction between the telescopic rod 9 and the first connecting rod 19, the second connecting rod 20 and the sliding rod 21.

[0075] When the elastic clamping plate 5 that clamps the piston ring moves on the inclined slide rod 21, and at the same time the movable inclined plate 4 moves away from the bottom supporting plate 6, the elastic clamping plate 5 moves obliquely upward toward the telescopic cylinder 16, driving the piston ring on the column 3 to move upward synchronously. In order to prevent the moving piston ring from being blocked by the column 3, the column 3 and the matching plate 22 slide along the matching groove 23 under the action of the movement of the piston ring, and the compression spring 24 is compressed, so that the piston ring is easy to detach from the column 3 (matching the downward movement of the column 3, two-way matching).

[0076] When the piston ring on the elastic clamping plate 5 that has separated from the column 3 is taken out, it is extended and reset by the telescopic cylinder 16. Under the action of the sliding rod 21, the connecting rod 14 and the elastic clamping plate 5 are first tilted downward and then move horizontally forward. The elastic clamping plate 5 is close to the wedge plate 15, and the front end of the elastic clamping plate 5 cooperates with the rear side surface of the wedge plate 15 to reset the elastic clamping plate 5 (that is, the wedge surface on the rear side of the wedge plate 15 is inserted into the angle formed by the front ends of the two clamping arms in the elastic clamping plate 5, so that the angle of the front ends of the two clamping arms is reopened to a certain angle). Finally, the telescopic limit rod 13 pushes the pressing cone 7 to reset the pressing cone 7 and the column 3 together.

[0077] In some embodiments, a through hole is provided in the base plate 2 to facilitate cleaning and prevent accumulation of debris and dust.

[0078] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0079] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
