Description

[0002] The oil pipe joint is a component used to connect the oil pipe. It connects two or more sections of the oil pipe together to form a complete oil circuit system to ensure that the oil can flow smoothly in the oil pipe. The oil pipe joint needs to have good sealing performance to prevent oil leakage and ensure the normal operation of the system. Therefore, the oil pipe joint needs to be polished during processing to prevent burrs or sharp edges on the oil pipe joint from damaging the oil pipe or affecting the sealing.

DETAILED DESCRIPTION

[0035] Reference Figure 1-Figure 13 The present invention proposes an automatic processing device for a hydraulic oil pipe joint, comprising a main body block 1, two clamping rods 2 are slidably installed on one side of the main body block 1, the spacing between the two clamping rods 2 can be adjusted, and the sides of the two clamping rods 2 that are close to each other are fixedly connected with an extrusion block 3, and a soft file 4 is rotatably connected between the two extrusion blocks 3. When the two clamping rods 2 are close to each other, the soft file 4 can be squeezed and bent; the main body of the soft file 4 is a soft memory metal, and its polishing surface is tungsten steel or diamond particles. During specific operation, find a standard oil pipe joint with a smooth surface and no impurities, place the soft file 4 against the oil pipe joint, adjust the two clamping rods 2 to be close to each other to clamp the oil pipe joint, and when the two clamping rods 2 are close to each other, the two extrusion blocks 3 are driven to move close to each other, and the two extrusion blocks 3 move close to each other to squeeze the soft file 4, and the soft file 4 is squeezed, deformed and bent to form an arc line that fits the surface of the oil pipe joint.

[0036] In actual situations, most of the oil pipe joints are cylindrical. When grinding the surface of the cylindrical oil pipe joints, using a flat file or other tools may cause the oil pipe joints to be over-ground and cause quality problems with the oil pipe joints. If a fixed-size tool is used, it is impossible to grind oil pipe joints of different diameters, so the following design is used.

[0037] like Figure 1 and Figure 2 As shown in the figure, a positioning mechanism is installed between the main block 1 and the soft file 4, and the positioning mechanism can fix the deformation of the soft file 4; when the soft file 4 is squeezed and deformed to fit the surface of the standard oil pipe joint, the shape of the soft file 4 is fixed by the positioning mechanism, thereby reducing the deformation of the soft file 4 during the grinding process and causing the oil pipe joint to be over-ground, thereby ensuring the grinding quality of the oil pipe joint.

[0038] In actual operation, whether using a flat file or a special arc file to grind the oil pipe joint, after the waste edges or surface particles are ground off, if the grinding operation continues, it is easy to cause over-grinding of the oil pipe joint, affecting the quality of the oil pipe joint. Therefore, the following design is made.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, a limit adjustment structure is installed on the main block 1, and the limit adjustment structure is used to prevent the soft file 4 from over-grinding the oil pipe joint; when the shape of the soft file 4 is adjusted, the limit adjustment structure changes with the shape of the soft file 4, so that the limit adjustment structure abuts against the surface of the oil pipe joint. When the soft file 4 completes grinding the waste edges and particles on the surface of the oil pipe joint and continues grinding, the soft file 4 cannot continue to grind the surface of the oil pipe joint due to the limit adjustment structure abutting against the surface of the oil pipe joint, thereby reducing excessive grinding of the oil pipe joint.

[0040] An adjustment structure is installed on the main block 1, and the adjustment structure can adjust the distance between the two clamping rods 2. The adjustment structure can also adjust the positioning mechanism to deform along with the deformation of the soft file 4. The adjustment structure can also adjust the limit adjustment structure. In actual operation, it is necessary to adjust the distance between the two clamping rods 2, and the two clamping rods 2 need to clamp the oil pipe joint, so as to limit the movement direction of the soft file 4 and reduce the skewness of the soft file 4 during the grinding process. In addition, it is necessary to adjust the limit adjustment structure, and at the same time, it is also necessary to fix the shape of the soft file 4 unchanged through the positioning mechanism. If adjustments are made one by one, it will take a lot of time, which will affect the processing efficiency.

[0041] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown in, the positioning mechanism includes a lifting block 5, a connecting plate 6, a telescopic assembly and a locking assembly; a lifting groove 9 is provided in the main body block 1, which is slidably matched with the lifting block 5, the top of the connecting plate 6 is fixedly connected to the lifting block 5, and the other end of the connecting plate 6 is rotatably connected to the middle of the top surface of the soft file 4, and the number of telescopic assemblies is multiple, and multiple telescopic assemblies are connected between the soft file 4 and the lifting block 5, and multiple telescopic assemblies are symmetrically arranged on both sides of the connecting plate 6; the locking assembly is used to fix the telescopic assembly, and the telescopic assembly includes a No. 1 inclined panel 7 and a No. 2 inclined panel 8; the top of the No. 1 inclined panel 7 is fixedly connected to the bottom of the lifting block 5, the inclined surface of the No. 1 inclined panel 7 and the inclined surface of the No. 2 inclined panel 8 are slidably matched, and the bottom end of the No. 2 inclined panel 8 is rotatably connected to the top surface of the soft file 4. In actual conditions, as Figure 7 As shown in FIG, the back of the soft file 4 is fixedly connected with a plurality of connectors, and the connecting plate 6 is rotatably connected to the middle row of connectors ( Figure 7 The connecting heads parallel to the width direction of the soft file 4 are in one row), the second inclined plate 8 is rotatably connected with the other rows of connecting heads. Because when the soft file 4 is bent, the horizontal distance between the two adjacent rows of connecting heads will become smaller, which requires the spacing between the two adjacent second inclined plates 8 to also become smaller, that is, the first inclined plate 7 and the second inclined plate 8 are rotated from Figure 1 The state in is transformed into Figure 2 In the state, since the relative positions of the multiple No. 1 inclined plates 7 will not change, the inclined surfaces of the No. 2 inclined plates 8 and the No. 1 inclined plates 7 slide in cooperation. When the No. 2 inclined plate 8 slides on the inclined surface of the No. 1 inclined plate 7, the greater the displacement of the No. 2 inclined plate 8 on the inclined surface of the No. 1 inclined plate 7, the smaller the spacing between the side surfaces of the No. 2 inclined plate 8 and the No. 1 inclined plate 7 that are opposite to each other. When the soft file 4 is bent, the spacing between the connectors farther away from the position of the connecting plate 6 is smaller, and thus the corresponding displacement between the No. 1 inclined plate 7 and the No. 2 inclined plate 8 is also greater. After adjusting the shape of the soft file 4, the positions of the No. 1 inclined plate 7 and the No. 2 inclined plate 8 are fixed by the locking assembly, thereby ensuring that the shape of the soft file 4 does not change during the grinding process. Due to the design of multiple rows of connectors, the soft file 4 is not easily affected by friction during the grinding process and is not easily hollowed out and deformed in the middle position, thereby ensuring the grinding effect of the oil pipe joint.

[0042] like Figure 1 , Figure 4 and Figure 8As shown in, the locking assembly includes a locking plate 18, a locking screw 19 and a tension spring 20; a moving groove that slides with the locking plate 18 is provided on the inner wall of one side of the transverse groove 11, and one end of the locking screw 19 is threadedly penetrates the main block 1 and is rotatably connected to the locking plate 18. Both sides of the locking plate 18 are fixedly connected to side blocks, and a limiting slide groove that slides with the side block is provided in the main block 1. The tension spring 20 is located in the limiting slide groove, and the two ends of the tension spring 20 are respectively fixedly connected to the side blocks and the inner walls of the limiting slide groove. The locking screw 19 is tightened to drive the locking plate 18 to slide in the moving groove. When the locking plate 18 abuts against the side surfaces of the No. 1 inclined plate 7 and the No. 2 inclined plate 8, the positions of the No. 1 inclined plate 7 and the No. 2 inclined plate 8 are fixed by friction. When necessary, friction surfaces or teeth are set on the sides of the No. 1 inclined plate 7 and the No. 2 inclined plate 8 to increase friction and ensure the locking effect.

[0043] like Figure 2 , Figure 3 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown in the figure, the limit adjustment structure includes a two-way hydraulic rod 10; a transverse groove 11 is opened on the main body block 1 to slide with the clamping rod 2, and the two-way hydraulic rod 10 is fixedly installed in the transverse groove 11. A reset spring is arranged in the two-way hydraulic rod 10, and the reset spring can drive the output shaft on the two-way hydraulic rod 10 to slide and reset; when the two clamping rods 2 move close to each other, the clamping rod 2 can squeeze one of the output shafts of the two-way hydraulic rod 10, and the other output shaft on the two-way hydraulic rod 10 extends out. In actual situations, when the soft file 4 grinds the waste edge or burr on the surface of the oil pipe joint, After that, one of the output shafts of the two-way hydraulic rod 10 is required to be against the surface of the oil pipe joint so that the soft file 4 cannot continue to grind the surface of the oil pipe joint. When the clamping rods 2 are close to each other, when grinding different oil pipe joints, the output shaft of the two-way hydraulic rod 10 extends to different lengths, and due to the changes between the oil pipe joints, its telescopic range will change slightly. In this way, the telescopic range of the output shaft of the two-way hydraulic rod 10 needs to change at different stages. The other output shaft of the two-way hydraulic rod 10 is composed of multiple telescopic output shafts 21 and filling columns, as shown in FIG. Fig.11 and Fig.12 As shown in the figure, a telescopic hole is provided in the chamber of the main body of the bidirectional hydraulic rod 10 to slide with the filling column. The length of the filling column is different, and the length of the filling column in the chamber of the bidirectional hydraulic rod 10 is also different. The telescopic output shaft 21 is fixedly installed at the end of the filling column. The cross-sectional view of the telescopic output shaft 21 is shown in FIG. Fig.12 As shown in , the telescopic output shaft 21 passes through the outside of the bidirectional hydraulic rod 10, as shown in Fig.11In the embodiment, the end of the telescopic output shaft 21 is squeezed by the clamping rod 2, so that the telescopic output shaft 21 and the filling column slide together, so that the telescopic column is retracted in the telescopic hole, so that the hydraulic cavity in the two-way hydraulic rod 10 becomes larger, and the other output shaft of the two-way hydraulic rod 10 is retracted in the two-way hydraulic rod 10. Assuming that there are 5 filling columns of different lengths, when the 5 filling columns are retracted at the same time, when one of the telescopic output shafts 21 is retracted into the shell of the two-way hydraulic rod 10, the locating pin at the end of the telescopic output shaft 21 is squeezed and retracted by the inner wall of the shell of the two-way hydraulic rod 10, so that the output shaft of the telescopic output shaft 21 can be retracted in the telescopic output shaft 21. At this time, the filling column cannot continue to retract. As the clamping rods 2 continue to move closer to each other, new telescopic columns gradually stop retracting, so that the telescopic length and telescopic amplitude of the other output shaft of the two-way hydraulic rod 10 change at different stages. After being fixed, the filling column will be locked by an electromagnet, so that the size of the hydraulic cavity of the two-way hydraulic rod 10 cannot be changed.

[0044] like Figure 2 and Figure 5 As shown in the figure, a through groove 12 is opened on the extrusion block 3, and the other output shaft of the two-way hydraulic rod 10 can slide in the through groove 12, so that the output shaft of the two-way hydraulic rod 10 and the clamping rod 2 can be on the same horizontal plane, thereby limiting the grinding trajectory of the soft file 4.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in, the adjustment structure includes a rack 13, a rotating rod 14 and a gear 15; a linear slide groove is provided in the main block 1, and the clamping rod 2 is fixedly mounted on the rack 13, and the rotating rod 14 is rotatably mounted on the main block 1, and one end of the rotating rod 14 extends into the linear slide groove, and the gear 15 is fixedly sleeved on the rotating rod 14, and the gear 15 is located in the linear slide groove, the rack 13 is meshed with the gear 15, and the two gears 15 pass through the center of the rotating rod 14 symmetrically; the adjustment structure also includes a threaded rod 16; the threaded rod 16 is fixedly connected to the top of the lifting block 5, and the end of the rotating rod 14 is provided with a threaded hole that is threadedly matched with the threaded rod 16, and a clamping sleeve 17 is rotatably sleeved on the clamping rod 2. In actual operation, a qualified oil pipe joint is taken out, and a straight soft file 4 is pressed against the oil pipe joint. The rotating rod 14 is rotated, and the rotating rod 14 drives the gear 15 to rotate. Due to the meshing of the gear 15 and the rack 13, the driving gear The strip 13 and the clamping rod 2 move toward each other synchronously. When the two clamping rods 2 approach each other, the two extrusion blocks 3 will be driven to move toward each other, and the soft file 4 will be squeezed and deformed by the two extrusion blocks 3. When the rotating rod 14 rotates, the threaded rod 16 and the rotating rod 14 are threadedly matched, so that the threaded rod 16 is retracted in the threaded hole, and the threaded rod 16 pulls the lifting block 5, and the lifting block 5 pulls the middle position of the connecting plate 6 and the soft file 4 to bend. Due to the bending of the soft file 4, the No. 1 inclined plate 7 and the connecting plate 6 move synchronously, and the No. 2 inclined plate 8 slides on the inclined surface of the No. 1 inclined plate 7, thereby adapting to the bending deformation of the soft file 4, so that the soft file 4 fits on the surface of the oil pipe joint. At the same time, the clamping sleeve 17 is clamped on both sides of the oil pipe joint. When the soft file 4 is ground, the friction between the oil pipe joint and the clamping rod 2 can be reduced, thereby reducing the wear on the oil pipe joint, ensuring the quality of the oil pipe joint, and also reducing the adjustment time and improving work efficiency.

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.
