[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments.

When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0031] like Figures 1 to 5As shown, an oil ring production device includes: a frame, a cylinder 11 installed on the top of the frame, a cutting assembly 4 for cutting the oil ring, and a regulator 5 for adjusting the height of the oil ring.

[0032] This device is used in conjunction with cutting and grinding equipment to facilitate cutting of heated cylindrical oil pipes, providing convenience for subsequent production processes and increasing the production efficiency and molding quality of subsequent devices.

[0033] The output end of the cylinder 11 is fixedly connected to the push block 12, and the cylinder 11 is fixedly connected to the frame. The push block 12 is provided with square grooves on both sides near the bottom. The push block 12 is driven to move by the output end of the cylinder 11, and the square groove opened at the bottom of the push block 12 drives the object installed in the square groove to move.

[0034] The clamping assembly 3 is rotatably connected to one side of the frame; the clamping assembly 3 consists of a rotating shaft 31, a first bearing 32 slidably installed in the square groove opened by the push block 12, and a second bearing 33 rotatably installed in the square groove opened by the clamping jaw. The first bearing 32 and the second bearing 33 are correspondingly installed in the corresponding square grooves and are connected to each other by a bearing fixing block. They rotate around the rotating shaft 31, and by applying force to the push block 12, the push block 12 moves downward, and the push block 12 pushes the first bearing 32 and the second bearing 33 installed in the square groove. The bearing fixing block rotates clockwise along the rotating axis, driving the left and right clamping jaws to open to both sides, thereby facilitating the placement of the material at the center of the clamping jaw.

[0035] A reset mechanism 2 is slidably connected to one side of the frame; the reset mechanism 2 includes: a sliding block 21 sliding on one side of the frame, the sliding block 21 is fixedly connected to the push block 12, a blocking ring 22 that helps to fix the sliding block 21, and a spring 23 that helps to reset the sliding block 21. When the force applied to the push block 12 is cancelled, the spring 23 pushes the push block 12 to move upward, and the push block 12 drives the second bearing 33 in the groove of the push block 12. The bearing fixing block rotates counterclockwise along the rotation axis, driving the left and right chucks to clamp the material, which is convenient for clamping the material. At the same time, the cylinder 11 does not work during clamping, reducing energy consumption.

[0036] The cutting assembly 4 is composed of a gear bar 41, a transmission wheel 42 meshing with the gear bar 41, a cutting head 44 for cutting the oil ring, and a rotator 43 for driving the oil ring to cut, and the rotator 43 includes a bidirectional screw 431, and the transmission wheel 42 is fixedly connected to one end of the bidirectional screw 431, and a shaft sleeve 432 threadedly connected to the bidirectional screw 431, the shaft sleeve 432 is divided into two groups and distributed along the center line of the bidirectional screw 431, and the bottom of the two groups of shaft sleeves 432 are fixedly connected with a connecting rod 433, the gear bar 41 is installed on one side of the sliding block 21, when the sliding block 21 slides down When the gears 43 are in motion, the rack is driven to move downward, and when the rack moves, the transmission wheel 42 is driven to rotate, causing the bidirectional screw 431 to rotate. At the same time, the two sets of threads on the bidirectional screw 431 are set in opposite directions, so that the shaft sleeves 432 connected at both ends of the bidirectional threads move toward the center synchronously. The connecting rod 433 at the bottom of the shaft sleeve 432 drives the cutting head 44 to perform secondary clamping and cutting on the heated oil pipe. The secondary positioning improves the accuracy of the oil pipe in the center position, which facilitates accurate cutting of the oil pipe. The residue generated during cutting will fall onto the cutting head 44 as the cutting head 44 moves left and right, making it easy to collect the residue generated during cutting.

[0037] It should be noted here that the oil pipe is heated and then cooled to shape. The main function of heating is to change the stress state of the material, reduce the residual stress generated during the cutting process, and improve the stability and service life of the oil ring. At the same time, the cutting of the material is more precise after it cools. The inner wall of the chuck at the top of the cutting head 44 is made of flexible material, such as soft silicone, to prevent damage to the surface of the oil ring when clamping it.

[0038] An adjuster 5 is installed at the bottom of the frame; the adjuster 5 includes a rotating motor 51, an output end of the rotating motor 51 is provided with a bevel gear 1, a threaded rod 52 meshing with the output end of the rotating motor 51, and a bevel gear 2 is provided on the top of the threaded rod 52, the bevel gear 1 and the bevel gear 2 are meshed with each other, and the bottom of the threaded rod 52 is rotatably connected to the frame, and a placement device 53 threadedly connected to the threaded rod 52, by starting the rotating motor 51, the threaded rod 52 is rotated, and the height of the placement device 53 can be adjusted, thereby adjusting the height of the oil pipe on the placement device 53, and assisting in adjusting the oil pipe cutting distance.

[0039] As a further improvement, the rotating motor 51 can be replaced with a manual rotation mode. By manually driving the gears, the height of the oil pipe can be adjusted more conveniently and can be adjusted at will, but it consumes manpower and can be adjusted according to actual working conditions.

[0040] As an extension of this patent, it also includes: a detection unit for detecting the cutting height of the oil ring; an information processing end for analyzing the data after detection by the detection end; a control unit for controlling the clamping height of the oil ring; the detection unit is electrically connected to the information processing end; the information processing end is electrically connected to the control unit, and the position of the work material before clamping, the height of the work material during clamping, and the position and height of the work material after clamping are monitored in real time through a CCD camera; and an electrical signal is transmitted to the control unit, and the control unit gives different control feedback according to different stages. For example, when the work material is placed on the placement table, when the clamping claw clamps the work material, the rotating motor 51 is controlled to rotate, thereby adjusting the height of the placement plate and assisting in cutting the work material; after the rotation time is determined, the historical data is transmitted to the information processing end for backup processing, thereby implementing automatic control of the work material.

[0041] In this embodiment, the real-time height of the oil pipe is detected by the detection end of the oil pipe position, and the inner diameter and outer diameter of the oil pipe are calculated at the same time. At the same time, the cutting speed of the cutting head 44 on the oil pipe is calculated. The steps for calculating the cutting speed of the cutting head 44 based on the inner diameter and outer diameter of the oil pipe are as follows:

[0042] S1. Set the state of the oil pipe height change ΔH1;

[0043] S2 extracts the voltages A1 and A2 of the rotating motor 51 and the cylinder 11;

[0044] S3 real-time acquisition of the initial height h1 of the tubing when the tubing height is not adjusted, and the height h2 of the tubing when the tubing is cut on the placement device 53;

[0045] S4 introduces the inner diameter w1 and outer diameter w2 of the oil pipe to calculate the actual length Δw of the oil pipe to be cut, and calculates the speed Δn required by the cutting head 44 according to the inner and outer diameters;

[0046] S5. Calculate the voltage adjustment value ΔA based on the comparison of the values ​​of h1 and h2 respectively.

[0047] When the bagged particles h1 differ from the reference value H, ΔA1 = h1 - (H + ΔW);

[0048] The controller compares ΔA with the set parameters and controls the voltage output to the rotating motor 51 through the voltage output fed back by ΔS. When it is detected that the oil pipe height is equal to the reference value, the voltage output to the rotating motor 51 is 0; thereby automatically adjusting the speed of the cutting head 44, cutting oil pipes of different thicknesses, and preventing energy waste.

[0049] Working principle: By controlling the pressing amplitude of the cylinder 11 and the voltage of the rotating motor 51, the clamping block is controlled to clamp the work material for positioning, and then the cutting head 44 is controlled to cut the work material and collect the cut debris to improve the accuracy of the work material forming. The speed required for the cutting head 44 to cut the work material can be calculated according to the different diameters of the work material, so that the work material can be cut more accurately to prevent damage to the work material.

[0050] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.

It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.

[0051] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
