Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of machining tools, and more specifically, to an automatic grinding and machining device for plunger pump fittings. Background Art

[0002] A plunger pump is a common positive displacement hydraulic pump that realizes the suction and discharge of liquid through the reciprocating motion of a plunger in a cylinder block. It is characterized by high pressure, high efficiency, and compact structure. There are multiple pipelines for liquid transportation connected to the plunger pump, so there are many connecting pipe fittings that cooperate with the plunger pump.

[0003] Since these pipe fittings need to withstand a large pressure during use, while ensuring their own hardness, machining accuracy is also very important. The traditional machining method is to fix the pipe fittings and then grind multiple positions on the pipe fittings through a multi-axis machine tool. However, since machining is required at different positions at multiple angles on the pipe fittings, the pipe fittings need to be repeatedly adjusted and fixed during machining, which results in low machining efficiency. At the same time, there may be an angular error during each fixation, affecting machining accuracy. Therefore, a device that can meet the multi-angle machining of pipe fittings is needed to improve machining efficiency. Summary of the Invention

[0004] To overcome the above defects, embodiments of the present disclosure provide an automatic grinding and machining device for plunger pump fittings, which is used to solve the technical problem that when some machine tools in the prior art perform multi-angle machining on pipe fittings, it is necessary to manually change the angle multiple times, resulting in low efficiency.

[0018] The following further elaborates on the present disclosure in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are merely for explaining the present disclosure and not for limiting the present disclosure.

[0023] In addition, in the description of this application, terms such as "first" and "second" are only used for distinguishing descriptions, and cannot be construed as indicating or implying relative importance.

[0024] As Figures 1 to 7 shown, it shows an automatic grinding processing device for a plunger pump fitting in an embodiment of the present disclosure, including a machine tool 1 and a fixed platform 2. The fixed platform 2 is slidably arranged on the machine tool 1, and further includes a support plate member 3, a docking rotating shaft 4, a pipe rotating mechanism, a docking pin 5 and a pressing and locking mechanism. There are multiple support plate members 3, and the multiple support plate members 3 are fixedly installed in the fixed platform 2. The docking rotating shaft 4 is rotatably connected to the support plate member 3, and the docking rotating shaft 4 is detachably connected to the pipe. The pipe is sleeved on the docking rotating shaft 4 and can rotate. A pipe rotating mechanism is rotatably connected to each docking rotating shaft 4. The pipe rotating mechanism is detachably connected to the pipe, and the pipe rotating mechanism is used to drive the pipe to rotate axially. There are multiple docking pins 5, and the docking pins 5 are fixedly connected to the support plate member 3. When the docking rotating shaft 4 drives the pipe rotating mechanism to rotate, the docking pins 5 are docked with the pipe rotating mechanism. The pressing and locking mechanism is fixedly connected to one end of the support plate member 3 away from the docking rotating shaft 4. There is a pressing and locking mechanism on each support plate member 3, and the pressing and locking mechanism is used to tightly fix the pipe during processing. The pipe is fixed on the docking rotating shaft 4, and the pipe rotating mechanism drives the pipe to rotate to adjust the processing angle. After rotating to a suitable angle, the pipe is clamped and fixed by the pressing and locking mechanism to prevent it from rotating during processing. When the pipe rotates, the pressing and locking mechanism can loosen the pipe to enable it to rotate.

[0025] As Figures 3 to 6As shown in the figure, a rotating shaft sleeve 6 is provided on the docking rotating shaft 4 and rotatably sleeved on the docking rotating shaft 4. The pipe fitting is detachably connected to the rotating shaft sleeve 6. The pipe fitting rotating mechanism is rotatably connected to the docking rotating shaft 4 on the side of the rotating shaft sleeve 6 close to the support plate member 3. When installing the pipe fitting, the central position of the pipe fitting is sleeved on the rotating shaft sleeve 6, and the pipe fitting can axially rotate on the docking rotating shaft 4 through the rotating shaft sleeve 6 so as to facilitate processing at various angles. When loading and unloading the pipe fitting, rotating the docking rotating shaft 4 to an inclined state enables convenient docking.

[0026] As Figures 3 to 6 As shown in the figure, the pipe fitting rotating mechanism includes a worm gear 9, an extension bracket 10, an umbrella-shaped plate 11, and a positioning groove 12. The worm gear 9 is rotatably sleeved on the docking rotating shaft 4. A plurality of extension brackets 10 are provided, and the plurality of extension brackets 10 are fixedly installed on the side of the worm gear 9 close to the rotating shaft sleeve 6. The plurality of extension brackets 10 are all detachably connected to the pipe fitting. The umbrella-shaped plate 11 is fixedly installed on the side of the worm gear 9 where the extension brackets 10 are provided. The positioning groove 12 is opened on the side of the worm gear 9 away from the extension brackets 10, and the positioning groove 12 is detachably connected to the docking pin 5. Support arms for fixing are provided on both sides of the pipe fitting, and the two extension brackets 10 can penetrate through the support arms to fix the pipe body. By rotating the worm gear 9, the rotation of the pipe body can be driven. Through the positioning groove 12, when the docking rotating shaft 4 rotates to replace the pipe fitting, the docking pin 5 can extend into the positioning groove 12, causing the worm gear 9 to be separated from the worm 22, but the rotation angle of the worm gear 9 does not change. After replacing the pipe fitting, rotate the docking rotating shaft 4 to make the worm gear 9 dock with the worm 22. At this time, the rotation angle of the worm gear 9 also remains fixed. The umbrella-shaped plate 11 can prevent chips generated during processing from falling into the drive groove 7. Chips between the worm gear 9 and the worm 22 will affect the accuracy of driving the rotation of the pipe fitting. At the same time, since the worm gear 9 cannot drive the worm 22 to rotate, the worm 22 can also lock the rotation of the pipe fitting during the grinding of the pipe fitting. By pressing the locking mechanism to fix the pipe fitting, it can also prevent the pipe fitting from wobbling due to the gap between the worm gear 9 and the worm 22.

[0027] As Figures 3 to 6As shown in the figure, the pressing and locking mechanism includes a support bracket 13, a pressing plate bracket 14, a stretching rod 16 and a stretching hole 18. The support bracket 13 is fixedly connected to the support plate member 3. The support bracket 13 can be in contact with one end of the pipe fitting away from the docking rotating shaft 4. The pressing plate bracket 14 is fixedly connected to the support plate member 3. A pressing plate 15 is rotatably connected to the pressing plate bracket 14. The pressing plate 15 is arranged above the support bracket 13. The stretching rod 16 is rotatably connected to the pressing plate 15. A stretching hook 17 is arranged at one end of the stretching rod 16 away from the pressing plate 15. The stretching hole 18 is opened on the support plate member 3. The stretching hole 18 is opened between the support bracket 13 and the pressing plate bracket 14. The stretching hole 18 communicates with the positioning groove 12. The stretching hook 17 can extend into the positioning groove 12 through the stretching hole 18. A lifting block 19 and a lifting roller 20 are arranged in the support bracket 13. The lifting block 19 is slidably arranged in the support bracket 13. A spring is connected between the lifting block 19 and the support plate member 3. The lifting roller 20 is rotatably connected to the lifting block 19. The lifting roller 20 can slide upward to be in contact with the pipe fitting. After the pipe fitting is installed, the pipe fitting is in contact with the support bracket 13. Then the pressing plate 15 is rotated so that the stretching hook 17 extends into the stretching hole 18. At this time, the pressing plate 15 is in contact with the pipe fitting. When the extrusion rod 23 is not in contact with the stretching hook 17, the spring pushes the lifting roller 20 to support the pipe fitting, so that the lifting roller 20 is in contact with the pipe fitting. When the pipe fitting rotates with the worm gear 9, the pipe fitting is in contact with the lifting roller 20, avoiding the contact between the support bracket 13 and the pipe fitting from affecting the rotation of the pipe fitting. By extruding the stretching hook 17 with the extrusion rod 23, the stretching rod 16 can be pulled to press the pressing plate 15 against the pipe fitting. At this time, the pressing plate 15 and the support bracket 13 fix the pipe fitting, and at the same time, the lifting roller 20 and the lifting block 19 are pressed into the support bracket 13. A support plate is arranged on the side of the stretching hole 18. When the extrusion rod 23 extrudes the stretching hook 17, the support plate supports the stretching rod 16 to prevent the stretching rod 16 from tilting.

[0028] As Figures 5 to 7 shown, the driving component includes a driving seat 21, a worm 22, an extrusion rod 23, a motor 24 and a driving cylinder 25. The driving seat 21 is fixedly connected to the side of the support plate member 3. The worm 22 is rotatably connected in the driving groove 7. The extrusion rod 23 is slidably arranged in the adjusting groove 8. The extrusion rod 23 is detachably connected to a plurality of stretching hooks 17. The motor 24 is fixedly installed on the driving seat 21. The output end of the motor 24 is in transmission connection with the worm 22. The driving cylinder 25 is fixedly installed in the driving seat 21. The output end of the driving cylinder 25 is fixedly connected to the extrusion rod 23. The extrusion rod 23 is arranged in a shape similar to a ladder, and the inclined surface on the stretching hook 17 is extruded through the central connecting rod, thereby driving the stretching rod 16 to slide. The output end of the motor 24 drives the worm 22 to rotate through a gearbox.

[0029] As Figures 5 to 7As shown, a driving groove 7, an adjusting groove 8 and a driving component are provided on the support plate member 3. The driving groove 7 is opened on the support plate member 3 and is arranged on the side of the pipe fitting rotating mechanism. The adjusting groove 8 is opened on the support plate member 3 and is arranged on the side of the pressing and locking mechanism. The driving component is fixedly connected to the side of the support plate member 3. Both the driving groove 7 and the adjusting groove 8 are connected to the driving component. The driving component is used to drive the pipe fitting rotating mechanism and the pressing and locking mechanism. When the pipe fitting rotates until the docking pin 5 and the positioning groove 12 are separated, the worm gear 9 meshes with the worm 22, and the worm 22 can drive the worm gear 9 to rotate. When the extrusion rod 23 does not contact the stretching hook 17, the lifting roller 20 can push the pipe fitting upward through the spring. At this time, the pipe fitting is separated from the support bracket 13. The driving grooves 7 on multiple support plate members 3 are communicated with each other, and the adjusting grooves 8 are also communicated with each other. The driving groove 7 has an opening near the worm gear 9, so that the worm 22 and the worm gear 9 can be in contact. A groove is provided at the position of the support plate member 3 below the pipe fitting, and the groove is communicated with the fixed platform 2. Drill chips and cooling oil can flow into the groove.

[0030] In some examples, the worm gear 9 rotates and tilts through the docking rotating shaft 4. The docking pin 5 is inserted into the positioning groove 12, the pipe fitting is sleeved on the rotating shaft sleeve 6, the arm on the side of the pipe fitting is aligned with the extension bracket 10, and the pipe fitting is rotated to contact the support bracket 13. At this time, the positioning groove 12 is separated from the docking pin 5, and the stretching hook 17 is extended into the stretching hole 18. At this time, the spring pushes the lifting roller 20 to support the pipe fitting. The output end of the motor 24 can drive the worm 22 to rotate, and the worm 22 drives the worm gear 9 to rotate, so as to adjust the angle of the pipe fitting. Thus, processing at multiple angles can be satisfied. When the required angle is adjusted, the output end of the motor 24 stops rotating. The output end of the driving cylinder 25 extends to push the extrusion rod 23, and the extrusion rod 23 contacts and squeezes the stretching hook 17, so that the stretching rod 16 pulls the pressing plate 15 to press the pipe fitting. At this time, the pipe fitting is processed. When the pipe fitting rotates again, the output end of the driving cylinder 25 shortens, so that the pressing of the pressing plate 15 on the pipe fitting is not tight, and the lifting roller 20 supports the pipe fitting, and the worm 22 drives the turbine to adjust the angle.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and not to limit them. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered by the scope of the claims of the present disclosure.
