Description

Technical Field

[0001] The present invention relates to a cutting mechanism, in particular to a cutting mechanism used in the field of oil production equipment processing. Background Art

[0002] The oil extraction machine is a kind of machine equipment for oil extraction, commonly known as the "knocking machine", which uses pressure to make the oil come out of the well. The oil extraction machine needs to be equipped with an appropriate oil pipe during the processing process. During the processing of the oil pipe, it needs to be cut. The traditional equipment has poor effect and needs further improvement.

[0003] The specification of Chinese patent CN108176891A discloses an oil pipe cutting device for an oil production machine, comprising a base, a processing plate, a driving mechanism, a plurality of clamping parts, a first rack, and a cutting part; a slide groove is provided on the base; the processing plate is slidably connected to the slide groove; the driving mechanism is used to drive the processing plate to move along the length direction of the slide groove; the plurality of clamping parts are sequentially distributed along the length direction of the slide groove, the clamping part comprises a mounting plate, a rotating shaft, a driven gear, a plurality of threaded rods, and two clamping units, the mounting plate is mounted on the processing plate, the rotating shaft is rotatably connected to the mounting plate; the driven gear is mounted on the rotating shaft; the plurality of threaded rods are sequentially distributed along the axial direction of the rotating shaft, and the plurality of threaded rods are all connected to the rotating shaft; the two clamping units are symmetrically distributed about the plurality of threaded rods, the clamping unit comprises a clamping plate, a plurality of connecting pipes, and the clamping plate is respectively threadedly connected to the plurality of threaded rods through the plurality of connecting pipes; the first rack is arranged along the length direction of the slide groove, and the first rack is meshed with the driven gear; the cutting part is used for cutting the oil pipe.

[0004] Most of the above-mentioned cutting devices and other cutting devices similar to the above-mentioned cutting devices can only cut the oil pipe. After cutting the oil pipe, due to the presence of fine scratches on the cut end surface of the oil pipe, it needs to be further polished to meet the subsequent use requirements. Only then can the cut oil pipe be obtained. In the prior art, the cut oil pipe usually needs to be transferred and polished using another polishing device, which not only increases the processing time, but also increases the cost of the processing equipment, and it is difficult to further improve the processing efficiency.

[0005] There are also some devices in the prior art that are equipped with both a cutting mechanism and a grinding mechanism, but they usually use two power sources to drive the cutting mechanism and the grinding mechanism to operate respectively, which also increases the energy consumption during processing; at the same time, most of the devices equipped with the cutting mechanism and the grinding mechanism cannot adjust the angle, and are difficult to be used in oil pipe cutting operations of different diameters.

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to provide a cutting mechanism for oil production equipment processing that can simultaneously cut and grind oil pipes, save equipment costs and energy consumption during processing, and be able to adapt to processing operations of oil pipes of different diameters.

[0007] In order to solve the above problems, the present invention provides a cutting mechanism for oil production equipment processing, including a cutting table, on which a support wheel and a mounting support are installed, the support wheel is used to rotatably support the oil pipe to be cut, and a cutting and grinding integrated mechanism is installed on the upper end of the mounting support, and the cutting and grinding integrated mechanism includes:

[0008] A mounting shell, the mounting shell is rotatably mounted on the upper end of the mounting support;

[0009] A protective shell, the protective shell is fixed to one side of the mounting shell;

[0010] A cutting wheel, the cutting wheel is rotatably mounted in the mounting shell;

[0011] A grinding wheel, which is also rotatably mounted in the mounting housing;

[0012] A main motor, which is fixed on one side of the protective shell;

[0013] The transmission structure is installed in the protective shell, and the main motor drives the cutting wheel and the grinding wheel to rotate simultaneously through the transmission structure;

[0014] A driving mechanism, the driving mechanism is installed on the inner side of the mounting shell away from the protective shell, and the driving mechanism is used to drive the grinding wheel to move along a certain arc and form different angles with the cutting wheel;

[0015] When the driving mechanism drives the grinding wheel to rotate along a certain arc, the transmission structure always plays a transmission role in driving the cutting wheel and the grinding wheel to rotate simultaneously.

[0016] In the above-mentioned cutting mechanism for oil production equipment processing, the main motor is used to drive the cutting wheel and the grinding wheel to rotate simultaneously through the transmission structure, so that the end face of the cut oil pipe can be ground while the oil pipe is cut, thereby completing the cutting and grinding operations at one time, which can save the processing time of grinding the oil pipe after cutting, so that the oil pipe after cutting is also ground at the same time, thereby improving the processing efficiency;

[0017] At the same time, under the premise of ensuring that the transmission structure always plays a transmission role in driving the cutting wheel and the grinding wheel to rotate simultaneously, the driving mechanism is used to drive the grinding wheel to move along a certain arc, so that different angles can be formed between the grinding wheel and the cutting wheel, so that it can fit oil pipes with different arcs and adapt to the simultaneous cutting and grinding of oil pipes with different outer diameters. This can expand the scope of application of the cutting mechanism used for oil production equipment processing and enhance its practicality.

[0018] As a further supplement to the present application, the transmission structure includes a driving gear, a cutting driven gear and a grinding driven gear, the driving gear is fixed to the output shaft of the main motor through a transmission shaft, the cutting driven gear is fixed to the cutting wheel through a transmission shaft, the grinding driven gear is connected to the grinding wheel through a transmission shaft, and the driving gear is meshed with the cutting driven gear and the grinding driven gear respectively;

[0019] The driving mechanism drives the grinding wheel to rotate along the axis of the transmission shaft on the driving gear.

[0020] When the main motor is started, the main motor drives the driving gear to rotate through one of the transmission shafts, and the driving gear drives the cutting driven gear and the grinding driven gear to rotate at the same time. The cutting driven gear and the grinding driven gear respectively drive the cutting wheel and the grinding wheel to rotate through the other two transmission shafts, thereby achieving the purpose of driving the cutting wheel and the grinding wheel to rotate at the same time, thereby achieving the purpose of cutting and grinding the oil pipe at the same time.

[0021] As a further supplement to this application, the driving mechanism includes:

[0022] Auxiliary motor;

[0023] A mounting block, one side of which is fixed to one end of the auxiliary motor;

[0024] A fixed shaft, one end of which is rotatably connected to one side of the mounting block, and the other end of which is fixed to the inner wall of the mounting shell;

[0025] A lead screw which is rotatably connected to the other side of the mounting block and fixed to the output shaft of the auxiliary motor;

[0026] A slider, wherein the slider is threadedly sleeved on the lead screw;

[0027] The sleeve ring is fixed to one side of the sliding block and is rotatably sleeved on one end of a transmission shaft on the grinding wheel.

[0028] As a further supplement to the present application, a distance connecting piece is installed between the transmission shaft on the driving gear and the transmission shaft on the grinding wheel. The distance connecting piece consists of a middle section support and two end circular rings. The two end circular rings of the distance connecting piece are respectively sleeved on one end of the transmission shaft on the driving gear and one end of the transmission shaft on the grinding wheel. The distance connecting piece is installed at the end of the transmission shaft away from the sleeve.

[0029] After the auxiliary motor is started, the auxiliary motor drives the lead screw to rotate, and the lead screw rotates to drive the slider to slide along the axis of the lead screw. At this time, the slider drives the transmission shaft on the grinding wheel to move along the axis of the lead screw through the collar. Since the auxiliary motor and the lead screw are both installed on the mounting block, and the mounting block is rotatably mounted on the fixed shaft, at the same time, the transmission shaft on the grinding wheel is restricted by the fixed-distance connecting piece to only make circular motion along the transmission shaft on the driving gear. Therefore, when the slider slides along the axis of the lead screw, the lead screw is restricted by the deflection direction of the collar and deflects along the axis of the fixed shaft, so that the grinding wheel can rotate along the axis of the transmission shaft on the driving gear, and the grinding driven gear is always meshed with the driving gear, so as to achieve stable transmission and drive the grinding wheel to move in a certain arc, thereby changing the angle between the grinding wheel and the cutting wheel, and achieving the purpose of cutting and grinding oil pipes with different outer diameters.

[0030] As a further supplement to the present application, anti-bias structures are installed on both sides of the grinding wheel. The anti-bias structures are composed of two groups of identical and symmetrically arranged anti-bias units. The anti-bias units are used to sense whether the center point of the grinding wheel is offset.

[0031] As a further supplement to the present application, the anti-bias unit includes:

[0032] A fixed sleeve plate, the fixed sleeve plate is fixedly mounted on the transmission shaft;

[0033] A movable sleeve plate, which is fixed to one side of the grinding wheel;

[0034] A compression spring, with two ends of the compression spring being respectively fixed to one side of the fixed sleeve plate and one side of the movable sleeve plate;

[0035] The pressure-sensitive sensor is fixed on a side of the fixed sleeve plate close to the movable sleeve plate, and the sensing end of the pressure-sensitive sensor is in contact with one side of the movable sleeve plate.

[0036] As a further supplement to the present application, a square limiting convex strip is integrally formed in the middle of the transmission shaft on the grinding wheel. The limiting convex strip movably passes through the grinding wheel and the movable sleeves on both sides of the grinding wheel. The two ends of the limiting convex strip are respectively fixed to one side of the two fixed sleeves.

[0037] As another improvement of the present application, two grinding wheels are provided, a gap is provided between the two grinding wheels, a plurality of separation clamps are provided in the gap between the two grinding wheels, and the plurality of separation clamps are all clamped on the transmission shaft and clamped by the two grinding wheels.

[0038] In summary, the main motor is used to drive the cutting wheel and the grinding wheel to rotate at the same time through the transmission structure. Specifically, when the main motor is started, the main motor drives the driving gear to rotate through one of the transmission shafts, and the driving gear drives the cutting driven gear and the grinding driven gear to rotate at the same time. The cutting driven gear and the grinding driven gear drive the cutting wheel and the grinding wheel to rotate through the other two transmission shafts respectively, so as to achieve the simultaneous driving of the cutting wheel and the grinding wheel to rotate, and the oil pipe end face can be polished at the same time after cutting, so as to complete the cutting and polishing operations at one time, which can save the processing time of polishing the oil pipe after cutting, so that the oil pipe after cutting is also polished at the same time, thereby improving the processing efficiency;

[0039] At the same time, under the premise of ensuring that the transmission structure always plays a transmission role in driving the cutting wheel and the grinding wheel to rotate simultaneously, a driving mechanism is used to drive the grinding wheel to move along a certain arc. Specifically, after the auxiliary motor is started, the auxiliary motor drives the lead screw to rotate, and when the lead screw rotates, it drives the slider to slide along the axis of the lead screw. At this time, the slider drives the transmission shaft on the grinding wheel to move along the axis of the lead screw through the collar. Since the auxiliary motor and the lead screw are both installed on the mounting block, and the mounting block is rotatably installed on the fixed shaft, at the same time, the fixed-distance connecting piece restricts the transmission shaft on the grinding wheel to only make circular motion along the transmission shaft on the driving gear. Therefore When the slider slides along the axis of the lead screw, the lead screw is limited by the deflection direction of the collar and deflects along the axis of the fixed shaft, so that the grinding wheel can rotate along the axis of the transmission shaft on the driving gear, and the grinding driven gear is always meshed with the driving gear, so that stable transmission can be achieved and the grinding wheel can be driven to move in a certain arc, so that different angles can be formed between the grinding wheel and the cutting wheel, so that oil pipes with different arcs can be fitted, and oil pipes with different outer diameters can be cut and polished at the same time, which can expand the application range of the cutting mechanism used for oil production equipment processing and enhance its practicality.

[0052] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0053] The first implementation method:

[0054] The present invention provides a cutting mechanism for oil production equipment processing, see Figure 1-Figure 4 , including a cutting table 100, on which a support wheel 200 and a mounting support 300 are mounted, the support wheel 200 is used to rotatably support the oil pipe to be cut, and a cutting and grinding integrated mechanism 400 is mounted on the upper end of the mounting support 300, and the cutting and grinding integrated mechanism 400 includes:

[0055] A mounting shell 1, the mounting shell 1 is rotatably mounted on the upper end of the mounting support 300;

[0056] A protective shell 2, the protective shell 2 is fixed to one side of the mounting shell 1;

[0057] A cutting wheel 3 is rotatably mounted in the mounting shell 1;

[0058] A grinding wheel 4 is also rotatably mounted in the mounting shell 1;

[0059] A main motor 5, which is fixed to one side of the protective shell 2;

[0060] The transmission structure 6 is installed in the protective shell 2, and the main motor 5 drives the cutting wheel 3 and the grinding wheel 4 to rotate simultaneously through the transmission structure 6;

[0061] The driving mechanism 7 is installed on the inner side of the mounting shell 1 away from the protective shell 2, and the driving mechanism 7 is used to drive the grinding wheel 4 to move along a certain arc and form different angles with the cutting wheel 3;

[0062] When the driving mechanism 7 drives the grinding wheel 4 to rotate along a certain arc, the transmission structure 6 always plays a transmission role in driving the cutting wheel 3 and the grinding wheel 4 to rotate simultaneously.

[0063] Based on the above structure, the main motor 5 is used to drive the cutting wheel 3 and the grinding wheel 4 to rotate simultaneously through the transmission structure 6, so that the end surface of the cut oil pipe can be ground while the oil pipe is cut, so that the cutting and grinding operations are completed at one time, which can save the processing time of grinding the oil pipe after cutting, so that the oil pipe after cutting is also ground, thereby improving the processing efficiency;

[0064] At the same time, under the premise of ensuring that the transmission structure 6 always plays a transmission role in driving the cutting wheel 3 and the grinding wheel 4 to rotate simultaneously, the driving mechanism 7 is used to drive the grinding wheel 4 to move along a certain arc, so that different angles can be formed between the grinding wheel 4 and the cutting wheel 3, so that they can fit oil pipes with different arcs, that is, different outer diameters, and adapt to the simultaneous cutting and grinding of oil pipes with different outer diameters, which can expand the scope of application of the cutting mechanism used for oil production equipment processing and enhance its practicality.

[0065] Figure 3 The transmission structure 6 is shown to include a driving gear 61, a cutting driven gear 62 and a grinding driven gear 63. The driving gear 61 is fixed to the output shaft of the main motor 5 through a transmission shaft 9, the cutting driven gear 62 is fixed to the cutting wheel 3 through the transmission shaft 9, and the grinding driven gear 63 is connected to the grinding wheel 4 through the transmission shaft 9. The driving gear 61 is meshed with the cutting driven gear 62 and the grinding driven gear 63 respectively.

[0066] The driving mechanism 7 drives the grinding wheel 4 to rotate along the axis of the transmission shaft 9 on the driving gear 61 .

[0067] Through the arrangement of the driving gear 61, the cutting driven gear 62 and the grinding driven gear 63, when the main motor 5 is started, the main motor 5 drives the driving gear 61 to rotate through one of the transmission shafts 9, and the driving gear 61 simultaneously drives the cutting driven gear 62 and the grinding driven gear 63 to rotate, and the cutting driven gear 62 and the grinding driven gear 63 respectively drive the cutting wheel 3 and the grinding wheel 4 to rotate through the other two transmission shafts 9, thereby achieving the purpose of driving the cutting wheel 3 and the grinding wheel 4 to rotate at the same time, thereby achieving the purpose of simultaneously cutting and grinding the oil pipe.

[0068] Figure 4-Figure 5 The driving mechanism 7 is shown to include:

[0069] Auxiliary motor 71;

[0070] A mounting block 72, one side of the mounting block 72 is fixed to one end of the auxiliary motor 71;

[0071] A fixed shaft 73, one end of which is rotatably connected to one side of the mounting block 72, and the other end of which is fixed to the inner wall of the mounting shell 1;

[0072] A lead screw 74, which is rotatably connected to the other side of the mounting block 72 and fixed to the output shaft of the auxiliary motor 71;

[0073] A slider 75, wherein the slider 75 is threadedly sleeved on the lead screw 74;

[0074] The sleeve ring 76 is fixed to one side of the slider 75 , and the sleeve ring 76 is rotatably sleeved on one end of the transmission shaft 9 on the grinding wheel 4 .

[0075] Figure 3 It is shown that a distance connecting piece 64 is installed between the transmission shaft 9 on the driving gear 61 and the transmission shaft 9 on the grinding wheel 4. The distance connecting piece 64 is composed of a middle section support and two end circular rings. The two end circular rings of the distance connecting piece 64 are respectively sleeved on one end of the transmission shaft 9 on the driving gear 61 and one end of the transmission shaft 9 on the grinding wheel 4. The distance connecting piece 64 is installed at the end of the transmission shaft 9 away from the collar 76.

[0076] By means of the arrangement of the fixed-distance connection piece 64, the auxiliary motor 71, the mounting block 72, the fixed shaft 73, the lead screw 74, the slider 75 and the collar 76, after the auxiliary motor 71 is started, the auxiliary motor 71 drives the lead screw 74 to rotate, and when the lead screw 74 rotates, the slider 75 is driven to slide along the axis of the lead screw 74. At this time, the slider 75 drives the transmission shaft 9 on the grinding wheel 4 to move along the axis of the lead screw 74 through the collar 76. Since the auxiliary motor 71 and the lead screw 74 are both mounted on the mounting block 72, and the mounting block 72 is rotatably mounted on the fixed shaft 73, at the same time, the fixed-distance connection piece 64 limits the transmission shaft 9 on the grinding wheel 4. It can only make circular motion along the transmission shaft 9 on the driving gear 61. Therefore, when the slider 75 slides along the axis of the lead screw 74, the lead screw 74 is limited by the deflection direction of the ring 76 to produce a deflection along the axis of the fixed shaft 73, so that the grinding wheel 4 can rotate along the axis of the transmission shaft 9 on the driving gear 61, and the grinding driven gear 63 is always engaged with the driving gear 61, so as to achieve stable transmission and drive the grinding wheel 4 to move in a certain arc, thereby changing the angle between the grinding wheel 4 and the cutting wheel 3, and achieving the purpose of cutting and grinding oil pipes with different outer diameters.

[0077] Figure 6 It is shown that both sides of the grinding wheel 4 are equipped with an anti-deflection structure 8, which is composed of two groups of identical and symmetrically arranged anti-deflection units. The anti-deflection unit is used to sense whether the center point of the grinding wheel 4 is offset. The anti-deflection unit includes:

[0078] A fixed sleeve 81, the fixed sleeve 81 is fixedly sleeved on the transmission shaft 9;

[0079] A movable sleeve plate 82, the movable sleeve plate 82 is fixed to one side of the grinding wheel 4;

[0080] A compression spring 83, two ends of which are respectively fixed to one side of the fixed sleeve plate 81 and one side of the movable sleeve plate 82;

[0081] The pressure-sensitive sensor 84 is fixed to one side of the fixed sleeve 81 close to the movable sleeve 82. The sensing end of the pressure-sensitive sensor 84 is in contact with one side of the movable sleeve 82. The pressure-sensitive sensor 84 is electrically connected to an external control terminal (not shown in the figure). The external control terminal adopts a programmable industrial controller commonly used in the prior art and suitable for this embodiment, which can meet the needs of controlling the start and stop of the main motor 5 and the auxiliary motor 71 and the operating mode (adjustment of the speed and direction).

[0082] By setting the fixed sleeve 81, the movable sleeve 82, the compression spring 83 and the pressure-sensitive sensor 84, under normal circumstances, the compression springs 83 on both sides of the grinding wheel 4 make the grinding wheel 4 located in the middle position (i.e., the position corresponding to the cutting wheel 3). When the grinding wheel 4 is subjected to force and deviates axially along the transmission shaft 9, the movable sleeve 82 on one side will be forced to move closer to the fixed sleeve 81, so that the pressure-sensitive sensor 84 installed on this side is pressurized. When the pressure exceeds the set threshold, it means that there is a large defect in the cutting end face of the oil pipe at this location (the cutting end face is uneven). The pressure-sensitive sensor 84 transmits the signal to the external control terminal and issues an alarm, so that the staff can find the disadvantage and stop the cutting operation, and promptly troubleshoot the problem to avoid the expansion of losses in subsequent cutting operations.

[0083] It should be noted that, according to usage requirements, when the pressure-sensitive sensor 84 receives a large pressure, the signal can be transmitted to the external control terminal, and the control terminal directly controls the main motor 5 and the auxiliary motor 71 to shut down, thereby directly terminating the cutting and grinding operations, and timely avoiding further expansion of losses in the current cutting operation.

[0084] Figure 6 It is shown that a square limiting convex strip 91 is integrally formed in the middle of the transmission shaft 9 on the grinding wheel 4. The limiting convex strip 91 movably passes through the grinding wheel 4 and the movable sleeves 82 on both sides of the grinding wheel 4. The two ends of the limiting convex strip 91 are respectively fixed to one side of the two fixed sleeves 81.

[0085] By setting the limiting convex strip 91, it is possible to simultaneously drive the grinding wheel 4 to rotate through the transmission shaft 9 and allow the grinding wheel 4 to have a certain deviation, thereby cooperating with the anti-deviation structure 8 to achieve the purpose of warning when defects occur on the end face of the oil pipe after cutting.

[0086] Second implementation method:

[0087] Fig. 9 Another cutting mechanism for oil production equipment processing is shown, which is different from the embodiment in that:

[0088] Two grinding wheels 4 are provided, and there is a gap between the two grinding wheels 4. A plurality of partition clamps 92 are provided in the gap between the two grinding wheels 4. The plurality of partition clamps 92 are all clamped on the transmission shaft 9 and clamped by the two grinding wheels 4. By providing two grinding wheels 4 and a partition clamp 92 between the two grinding wheels 4, the spacing between the two grinding wheels 4 can be changed to adapt to oil pipe cutting gaps of different widths. Effective grinding and anti-deviation warning operations can be performed on cutting gaps of different widths.

[0089] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
