Description

Technical Field

[0001] The invention relates to the technical field of piston ring numerical control milling machine structures, in particular to a piston ring numerical control milling and slicing machine. Background Art

[0002] The piston ring CNC milling and slicing machine is a CNC special machine tool specially used for the milling and slicing of piston ring blanks. After production, the piston rings are counted by the counting device on the machine tool to facilitate subsequent quantitative transportation and packaging.

[0003] Since there is an error in the thickness of the piston ring, there may be a deviation in the thickness after a fixed number of piston rings are stacked. However, the method of obtaining a fixed number of piston rings by calculating the thickness is not accurate enough, and the number of piston rings on the column where the piston rings are placed is often insufficient or excessive.

[0004] Existing piston ring CNC milling and slicing machines do not have the function of automatically increasing or decreasing the piston rings on the column. Manual increase or decrease of piston rings is required to ensure a fixed number for each batch. The operation is time-consuming and labor-intensive, and has low accuracy, making it difficult to ensure a fixed number.

[0005] Therefore, we propose a CNC milling and slicing machine for piston rings. Summary of the invention

[0006] The object of the present invention is to provide a piston ring CNC milling and slicing machine to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides a piston ring CNC milling and slicing machine tool, the main body of which is a bed with a power transmission device inside, and a base plate is provided on the bed; a plurality of columns for sleeved piston rings are provided above the base plate, and a counting system for detecting the number of piston rings on the columns is provided on the bed;

[0008] The base plate is provided with a ring supplementing mechanism for supplementing the number of piston rings on the column and a ring reduction mechanism for reducing the number of piston rings on the column;

[0009] The base plate is also provided with a driving mechanism that provides power for the ring-filling mechanism and the ring-reducing mechanism. The driving mechanism is provided with a switching component that controls the driving mechanism to drive the ring-filling mechanism or the ring-reducing mechanism, and the switching component and the driving mechanism are both electrically connected to the counting system.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The number of piston rings is detected by the counting system. When the number of piston rings is insufficient, the incomplete bevel gear is engaged with the inner gear ring. At this time, the self-rotating rod and the push plate do not rotate. The motor rotates counterclockwise to drive the plug-in plate to move, and the piston ring in the ring-releasing part is taken out and put on the column, thereby completing the increase of the number of piston rings on the column.

[0012] When the number of piston rings exceeds the limit, the plug-in board does not operate by cooperating with the driving part, and the rotating rod reciprocates at a certain angle, cooperating with the lifting assembly and the push plate to push the piston ring at the bottom of the column out of the column, thereby completing the reduction of the number of piston rings;

[0013] This method increases the efficiency of the device and saves time and effort by collecting images and coordinating the addition, removal and transportation of piston rings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0034] like Figure 1-5 FIG. 1 is a schematic diagram of a piston ring CNC milling and slicing machine tool according to an embodiment of the present invention: Embodiment 1

[0035] A numerically controlled milling slicing machine for piston rings, with the main body being a machine tool bed 1 internally provided with a power transmission device. A base plate 2 is provided on the machine tool bed 1; a plurality of columns 3 for sleeving piston rings 100 are provided on the base plate 2, and a counting system for detecting the number of piston rings 100 on the columns 3 is provided on the machine tool bed 1.

[0036] A ring supplementing mechanism 4 for supplementing the number of piston rings 100 on the columns 3 and a ring reducing mechanism 5 for reducing the number of piston rings 100 on the columns 3 are provided on the base plate 2;

[0037] A driving mechanism 6 for providing power to the ring supplementing mechanism 4 and the ring reducing mechanism 5 is further provided on the base plate 2.

[0038] Preferably, the column 3 is composed of a plurality of frustum columns, and the side of the column 3 is uneven, so that a plurality of piston rings 100 sleeved on the column 3 are distributed in a certain staggering manner, that is, there is a stagger between two adjacent piston rings 100 on the column 3, so as to facilitate the counting system to accurately measure the piston rings 100 on the column 3. A guide column 300 in a frustum structure is fixedly connected to the top of the column 3, which is convenient for the piston rings 100 on the plugging plate 421 to be accurately sleeved on the guide column 300 and the column 3 under circular motion.

[0039] The ring supplementing mechanism 4 includes a limit frame plate 40 fixedly arranged on the base plate 2. A ring dropping port 401 is formed on the limit frame plate 40, and a ring placing member 41 for accommodating the piston rings 100 is arranged above the ring dropping port 401;

[0040] A ring taking member 42 is also slidably connected to the limit frame plate 40. The driving mechanism 6 can drive the ring taking member 42 to perform a circumferential movement along the circumferential side of the limit frame plate 40, so that the ring taking member 42 first takes the piston rings 100 in the ring placing member 41 through the ring dropping port 401, sleeved the piston rings 100 on the column 3, and finally makes the ring taking member 42 separate from the column 3.

[0041] Preferably, the ring placing member 41 is composed of two arc-shaped plates 410 and a connecting rod 411 located between the two arc-shaped plates 410, and one of the arc-shaped plates 410 is fixedly connected to the limit frame plate 40.

[0042] The limit frame plate 40 is in a shape of a Chinese character 'hui'; the ring taking member 42 includes a sliding plate 420 slidable between the inner circle and the outer circle of the limit frame plate 40, two L-shaped plugging plates 421 and a connecting rod 422;

[0043] One end of the sliding plate 420 is connected and fixed to a plug-in plate 421, and the other end of the sliding plate 420 is connected and fixed to another plug-in plate 421 through a connecting rod 422. The plug-in plate 421 is provided with a plug-in groove that cooperates with the piston ring 100. A telescopic plate 423 with a tension spring inside is provided on the side of the sliding plate 420. One end of the telescopic plate 423 is rotatably connected to the connecting rod 422, and the other end of the telescopic plate 423 is fixed with a matching part 43 that cooperates with the driving mechanism 6.

[0044] Furthermore, the two plug-in plates 421 are arranged opposite to each other. When the ring taking member 42 passes through the ring dropping opening 401 , the plug-in grooves in the two plug-in plates 421 jointly take a piston ring 100 in the ring placing member 41 .

[0045] It is worth noting that the movable plug board 421 is always in a horizontal state, and the plug slot is always oriented toward the column 3. When the sliding plate 420 slides in the limiting frame plate 40, the limiting frame plate 40 is in a U-shaped shape, so the sliding plate 420 will not flip and rotate, and the sliding plate 420 will always remain in a horizontal state, thereby ensuring that the plug board 421 is always in a horizontal state;

[0046] The horizontally movable plug-in plate 421 first passes through the ring-releasing member 41, and then the plug-in groove is inserted into the piston ring 100 at the bottom of the ring-releasing member 41, and the piston ring 100 is driven to move. Then, when the plug-in plate 421 drives the piston ring 100 to move downward, the piston ring 100 is driven to be inserted into the column 3. Finally, the plug-in plate 421 is away from the column 3, and the plug-in plate 421 is away from the piston ring 100 inserted into the column 3, thereby completing the increase in the number of piston rings 100 on the column 3.

[0047] The ring reducing mechanism 5 includes a self-rotating rod 51 rotatably connected to the base plate 2, a lifting assembly 52 supported at the bottom of the column 3, and a driving member 53 that cooperates with the driving mechanism 6 and is used to realize the reciprocating rotation of the self-rotating rod 51;

[0048] The self-rotating rod 51 is also provided with a push assembly that cooperates with the bottom of the column 3, and there is a gap between the bottom surface of the column 3 and the top surface of the base plate 2 for the push assembly to pass through; the push assembly includes a push plate 540 fixedly arranged at the lower part of the self-rotating rod 51 and a guide block 541 fixedly connected to the lower side of the push plate 540, and the guide block 541 and the lifting assembly 52 are provided with induction sensors that cooperate with each other, and the top surface of the base plate 2 is provided with a matching groove 200 with an arc structure and slidingly matched with the guide block 541;

[0049] The mating driving member 53 acts on the rotating rod 51, so that the rotating rod 51 drives the guide block 541 to slide back and forth in the mating groove 200, wherein the guide block 541 makes the lifting assembly 52 cooperate with the push plate 540 to rise and fall through the induction sensor, so that the push plate 540 can smoothly pass through the gap between the bottom surface of the column 3 and the top surface of the base plate 2, and push the piston ring 100 out of the bottom of the column 3, thereby reducing the number of piston rings 100 on the column 3.

[0050] The lifting assembly 52 includes two telescopic cylinders 520 correspondingly arranged below the column 3. A suction plate 521 that cooperates with the bottom of the column 3 is fixedly connected to the telescopic shaft of the telescopic cylinder 520, and the two telescopic cylinders 520 are distributed with a gap.

[0051] Furthermore, the telescopic cylinder 520 is electrically connected to a counting system.

[0052] Furthermore, there is a gap between the bottom surface of the column 3 and the top surface of the base plate 2 for allowing the push plate 540 to pass through, and the gap is 1.5 times the height of the piston ring 100, so that the push plate 540 can only push out one piston ring 100 at a time.

[0053] In some embodiments, the base plate 2 is further provided with a collecting groove for receiving the piston ring 100 pushed out by the push plate 540 .

[0054] In some embodiments, the piston ring 100 pushed out by the push plate 540 is picked up manually or by an external machine and sent to the next process.

[0055] Furthermore, the adsorption plate 521 is preferably a magnetic plate, and a matching magnetic plate magnetically connected to the magnetic plate is embedded in the upper part of the bottom of the corresponding column 3. The bottom of the column 3 is an elastic rubber layer, which facilitates the piston ring 100 to push through the gap between the column 3 and the base plate 2 under the action of the push plate 540;

[0056] The driving mechanism 6 includes a motor 61 fixedly mounted on the base plate 2, the output shaft of the motor 61 is fixedly connected to a rotating rod 62, and the end of the rotating rod 62 is also provided with an incomplete bevel gear 64 meshing with the matching portion 43 and the matching driving member 53;

[0057] The incomplete bevel gear 64 and the matching portion 43 are located on the same horizontal axis.

[0058] Furthermore, the power transmission device in the bed 1 includes a power supply, and the motor 61 is connected to the power supply through a circuit.

[0059] Furthermore, the mating driving member 53 includes a servo motor, which is fixed on the base plate 2, and drives the self-rotating rod 51 to reciprocate through the servo motor;

[0060] The matching portion 43 includes an inner gear ring 430 connected to the telescopic plate 423 and a limiting cylinder 431 fixedly connected to the limiting frame plate 40 and rotating in cooperation with the inner gear ring 430 .

[0061] The counting system includes a central processing unit, a camera device and a light source which are connected to each other by signals. The light source irradiates the piston ring 100 on the column 3 , and the camera device captures the position of the piston ring 100 on the column 3 .

[0062] For details, please refer to the prior art: A piston ring 100-point counting system based on machine vision and its counting method in publication number CN104239950B;

[0063] The working principle of the present invention is roughly as follows:

[0064] When the counting system detects that the number of piston rings 100 on the column 3 does not meet the requirement:

[0065] If the number of piston rings 100 is insufficient, the motor 61 rotates counterclockwise, the servo motor does not rotate, the self-rotating rod 51 does not rotate, the incomplete bevel gear 64 drives the inner gear ring 430 to rotate counterclockwise, and the inner gear ring 430 then drives the ring taking member 42 to rotate counterclockwise. During the counterclockwise rotation of the ring taking member 42, the telescopic plate 423 is adaptively telescoped, so that the ring taking member 42 first passes through the ring drop opening 401 to take the piston ring 100 in the ring placing member 41, and then the piston ring 100 is inserted into the column 3, so as to replenish the piston ring 100;

[0066] If the number of piston rings 100 exceeds the limit, the motor 61 stops rotating and the servo motor rotates, driving the rotating rod 51 and the push plate 540 to rotate back and forth at a certain angle, and through the cooperation of the guide block 541 and the lifting assembly 52, the push plate 540 pushes out the piston ring 100 located at the bottom of the column 3, thereby reducing the piston ring 100 on the column 3.

[0067] The operation steps for reducing the number of piston rings 100 located at the bottom of the column 3 one by one by using the push plate 540 are as follows:

[0068] S1: In the initial state, the two adsorption plates 521 are supported at the bottom of the column 3, and then the push plate 540 on the right side rotates. At this time, the inductive sensor in the guide block 541 is close to the corresponding two positions of the inductive sensor on the telescopic cylinder 520 on the right side, so that the telescopic cylinder 520 on the right side shrinks longitudinally downward (the telescopic cylinder 520 shrinks downward until the inductive sensor can slide smoothly in the matching groove 200), and then the adsorption plate 521 on the right side is separated from the column 3, so that the push plate 540 pushes the piston ring 100 at the bottom of the column 3 to pass through the adsorption plate 521 on the right side (in the initial state, there is a gap between the bottom surface of the column 3 and the top surface of the base plate 2 for the push plate 540 to pass through, and the gap is 1.5 piston ring 100 heights, so that the push plate 540 only pushes out one piston ring 100 at a time);

[0069] S2: The push plate 540 continues to rotate, and the inductive sensor in the guide block 541 moves away from the inductive sensor on the right telescopic cylinder 520, so that the right telescopic cylinder 520 is reset and extended, so that the right suction plate 521 is reconnected and fixed to the column 3. At this time, the push plate 540 presses the piston ring 100 between the two suction plates 521.

[0070] S3: The push plate 540 continues to rotate, and the inductive sensor in the guide block 541 approaches the inductive sensor on the telescopic cylinder 520 on the left, so that the telescopic cylinder 520 on the left contracts, and the suction plate 521 on the left separates from the column 3, so that the push plate 540 presses the piston ring 100 at the bottom through the suction plate 521 on the left, so that the piston ring 100 is safely separated from the column 3, and the deduction work is completed;

[0071] It should be noted that, during this process, the two adsorption plates 521 cooperate with each other alternately, which ensures that the piston ring 100 is separated from the bottom of the column 3 and that the position of the column 3 remains unchanged. Embodiment 2

[0072] Please refer to Figure 6-Figure 18 , a piston ring CNC milling and slicing machine tool, based on the embodiment 1, the second embodiment also includes a switching component 7 arranged on the driving mechanism 6 and a movable sleeve 63 sleeved on the outer periphery of the rotating plug rod 62 (a limiting groove is provided on the rotating plug rod 62, and a limiting plate is provided in the movable sleeve 63 to slide with the limiting groove), the movable sleeve 63 can move circumferentially and axially relative to the rotating plug rod 62, and the end of the movable sleeve 63 is connected and fixed to the incomplete bevel gear 64; the switching component 7 controls the meshing matching portion 43 or the meshing matching driving member 53 of the incomplete bevel gear 64;

[0073] The switching assembly 7 includes a cylinder 71 fixed on the motor 61, and the output shaft of the cylinder 71 is fixedly connected with a movable plate 72, the movable plate 72 is rotatably connected to the movable sleeve 63, and the movable plate 72 drives the movable sleeve 63 to move along its axial direction under the drive of the cylinder 71.

[0074] The switching assembly 7 and the driving mechanism 6 are both electrically connected to the counting system;

[0075] In the second embodiment, the mating driving member 53 is two bevel gears 530 fixedly mounted on the upper end of the self-rotating rod 51, and the two bevel gears 530 are spaced apart from each other. The incomplete bevel gear 64 can mesh with the two bevel gears 530 through the switching assembly 7. Preferably, the tooth surfaces of the two bevel gears 530 are arranged opposite to each other. Driven by the driving mechanism 6, the mating driving member 53 causes the self-rotating rod 51 to drive the guide block 541 to slide back and forth in the mating groove 200;

[0076] When the incomplete bevel gear 64 meshes with the two bevel gears 530 , the motor 61 drives the incomplete bevel gear 64 to rotate, and acts on the two bevel gears 530 in sequence, so that the rotation rod 51 rotates clockwise and counterclockwise alternately.

[0077] Furthermore, the cylinder 71 is electrically connected to the counting system, and the cylinder 71 performs corresponding actions according to feedback from the counting system.

[0078] Furthermore, the power transmission device in the bed 1 also includes an air pump, and the cylinder 71 is connected to the air pump through an air path.

[0079] When the counting system detects that the number of piston rings 100 on the column 3 does not meet the requirement:

[0080] If the number of piston rings 100 is insufficient, the cylinder 71 is used to engage the incomplete bevel gear 64 with the inner gear ring 430, and the motor 61 is rotated counterclockwise. At this time, the rotation rod 51 does not rotate, and the incomplete bevel gear 64 drives the inner gear ring 430 to rotate counterclockwise, and the inner gear ring 430 then drives the ring taking member 42 to rotate counterclockwise. During the counterclockwise rotation of the ring taking member 42, the telescopic plate 423 is adaptively telescoped, so that the ring taking member 42 first passes through the ring drop opening 401 to take the piston ring 100 in the ring placing member 41, and then the piston ring 100 is inserted into the column 3, so as to replenish the piston ring 100;

[0081] If the number of piston rings 100 exceeds the limit, the incomplete bevel gear 64 is meshed with the two bevel gears 530 through the cylinder 71, and the motor 61 is rotated, driving the rotating rod 51 and the push plate 540 to reciprocate at a certain angle, and through the cooperation of the guide block 541 and the lifting assembly 52, the push plate 540 pushes out the piston ring 100 located at the bottom of the column 3, thereby reducing the piston ring 100 on the column 3.

[0082] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
