Description

Technical Field

[0002] The bearing seat is an engineering accessory that can bear comprehensive loads. It has the characteristics of compact structure, flexible rotation, and easy installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is the so-called bearing seat. When the shaft and the bearing seat are installed, the bearing needs to be assembled. Therefore, the bearing seat should be provided with a mounting hole for installing the bearing, such as Figure 1 A common bearing seat has two mounting holes for mounting the bearing, and the holes are located on both sides of the bearing seat. In order to process the two mounting holes, the usual practice is to install the bearing seat on a milling machine twice and mill it twice in succession to process the two mounting holes.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 7 As shown, a processing equipment dedicated to the production of outer spherical bearing seats includes a machine body 6, a control box 7, an operation panel 10, a workbench 4, a spindle 8 and a clamping assembly. The control box 7 and the operation panel 10 are respectively installed on the side and front of the machine body 6. The workbench 4 is slidably arranged on the machine body 6. There are two spindles 8 and two clamping assemblies. The spindle 8 is installed on the machine body 6. The clamping assembly includes a mounting frame 12, a positioning plate 21 and a cylinder 9. The mounting frame 12 and the positioning plate 21 are fixed on the workbench 4. The cylinder 9 is fixed on the mounting frame 12. A pressing plate 11 for pressing the bearing seat 1 is arranged on the piston of the cylinder 9. A positioning column 22 for positioning the bearing seat 1 is arranged on the positioning plate 21. A first driving assembly is provided for driving the workbench 4 to slide horizontally, and a second driving assembly is also provided on the inner side of the fuselage 6 for driving the main shaft 8 to rotate. A tool shaft 5 is provided on the main shaft 8, and the extension line of the axis of the tool shaft 5 is located between the pressure plate 11 and the positioning plate 21. The tool shaft 5 is provided with at least two mounting grooves 13 along its length direction. A cutting assembly 23 for processing the mounting hole 2 of the bearing seat 1 is rotatably provided in the mounting groove 13. A power assembly for driving the cutting assembly 23 to rotate is provided in the tool shaft 5. The cutting assembly 23 has two states: perpendicular to the tool shaft 5 and accommodated in the mounting groove 13, and the minimum distance between the two cutting assemblies 23 along the length direction of the tool shaft 5 is greater than the thickness of the bearing seat 1.

[0025] The cutting assembly 23 includes a tool holder 25, an end facing tool 24 and a rotating shaft 35. The end facing tool 24 is detachably mounted on the tool holder 25. The rotating shaft 35 is fixedly connected to the tool holder 25, and both ends of the rotating shaft 35 are rotatably connected to the tool shaft 5. When the tool holder 25 is rotated to be perpendicular to the tool shaft 5, the side of the tool holder 25 abuts against the side of the mounting groove 13. The end facing tool 24 and the tool holder 25 are detachable, and can be easily replaced after the end facing tool 24 is worn. When the end facing tool 24 is processing the mounting hole 2 of the bearing seat 1, the tool holder 25 abuts against the side of the mounting groove 13, thereby providing force support for the tool holder 25, avoiding the force acting on the end facing tool 24 during cutting to be concentrated on the gear 34 and the annular gear block 39, and the overall structure is more stable and reliable.

[0026] The power assembly includes a gear 34, a movable sleeve 28, a hydraulic cylinder 29, a piston plate 26, a spring 27, a guide tube 17 and an oil inlet pipe 14. The gear 34 is fixed to the middle of the tool holder 25. The hydraulic cylinder 29 has two oil storage chambers 36. The piston plate 26 is provided with two and is slidably arranged in the two oil storage chambers 36 respectively. The guide tube 17 is connected to the two oil storage chambers 36, and one end of the guide tube 17 extends to the outside of the main shaft 8. The oil inlet pipe 14 is a three-way pipe structure, and the first flow channel of the oil inlet pipe 14 is connected to the oil storage chamber 36. The first flow port is provided with an oil inlet control valve 15, the second flow port is provided with an oil discharge control valve 16, the third flow port is rotatably connected with the guide pipe 17, two movable sleeves 28 are provided, and are slidably arranged on the outside of the hydraulic cylinder 29, the movable sleeve 28 has an annular gear block 39 that cooperates with the gear 34, and the movable sleeve 28 is provided with a convex rod 40, one end of the convex rod 40 passes through the hydraulic cylinder 29 and is fixedly connected with the piston plate 26, the spring 27 is sleeved on the outside of the convex rod 40, and exerts a force on the piston plate 26 to move away from the movable sleeve 28. The force of the movable sleeve 28, the oil inlet control valve 15 and the oil storage control valve respectively control the oil inlet and oil discharge of the oil storage chamber 36. When the oil pressure in the oil storage chamber 36 increases, the piston plate 26 pushes the convex rod 40 and the movable sleeve 28 to slide. Relying on the cooperation of the annular gear block 39 and the gear 34, the tool holder 25 drives the end face turning tool 24 to rotate 90°, so that the end face turning tool 24 rotates from the mounting groove 13 to a state perpendicular to the tool shaft 5. In order to ensure the stability of the end face turning tool 24 during processing, the oil in the oil storage chamber 36 is The pressure needs to be maintained at a relatively high value, so that the end turning tool 24 will not drive the movable sleeve 28 to slide in the opposite direction when it is subjected to processing resistance. After the mounting hole 2 is processed, the oil pressure in the oil storage chamber 36 is reduced, and the spring 27 acts on the piston plate 26 to make the convex rod 40 drive the movable sleeve 28 to slide in the opposite direction. In this way, the gear 34 drives the tool holder 25 and the end turning tool 24 to rotate into the mounting groove 13, so that the end turning tool 24 can be stored, thereby facilitating the subsequent disassembly of the bearing seat 1.

[0027] The hydraulic cylinder 29 includes a cylinder body 33 and a cylinder head 31. Two cylinder heads 31 are provided and fixedly connected to the cylinder body 33 by bolts. The guide pipe 17 is installed on one of the cylinder heads 31. A limit column 37 for limiting the sliding distance of the two piston plates 26 is provided in the cylinder body 33. A boss 41 penetrating the piston plate 26 is provided in the middle of the cylinder body 33. A guide hole 30 is provided between the two bosses 41. The guide hole 30 connects the two oil storage chambers 36. The cylinder body 33 has a position corresponding to the position between the two cutting assemblies 23 and the cutter assembly 23. The annular convex 32 matches the inner hole of the shaft 5, and the piston plate 26 is slidably installed on the boss 41. Such a design can make the two oil storage chambers 36 smoothly realize oil circuit communication, and make the two piston plates 26 approach each other when the oil pressure increases, and make the two piston plates 26 move away from each other when the oil pressure decreases. The limit column 37 can control the sliding distance of the piston plate 26. Combined with the module, number of teeth and rotation angle of the gear 34, the length of the sliding distance can be accurately controlled to achieve the effect of rotating the end turning tool 24 90°.

[0028] The movable sleeve 28 includes two semi-cylindrical combination sleeves 38, each combination sleeve 38 has at least two protruding rods 40, and the two combination sleeves 38 are spliced ​​to form a complete movable sleeve 28. The split structure can facilitate the movable sleeve 28 to be installed on the hydraulic cylinder 29, and the manufacturing difficulty of the movable sleeve 28 is smaller.

[0029] There are four mounting grooves 13 and four cutting assemblies 23, and every two mounting grooves 13 are symmetrically distributed at 180° with the same position of the cutter shaft 5 as the center. Two cutting assemblies 23 process the mounting hole 2 of the same bearing seat 1, which can effectively speed up the cutting speed and thus greatly improve the processing efficiency. At the same time, the two mounting grooves 13 pass through the entire cutter shaft 5, so that when cutting the mounting hole 2 of the bearing seat 1, the iron filings generated can pass through the mounting grooves 13 smoothly, and will not accumulate in the cutter shaft 5 to affect the sliding of the movable sleeve 28.

[0030] The first driving assembly includes a first motor 3 and a screw, both ends of which are rotatably connected to the fuselage 6, and the screw is fixed on the output shaft of the first motor 3, and the middle part of the screw is threadedly connected to the workbench 4. The first motor 3 drives the screw to rotate, so that the workbench 4 can move horizontally on the fuselage 6, thereby smoothly realizing the processing and disassembly of the mounting hole 2 of the bearing seat 1.

[0031] The second driving assembly includes a second motor 18, a driving pulley 19, a driven pulley 42 and a belt 20. The driving pulley 19 is fixed on the output shaft of the second motor 18, the driven pulley 42 is fixed on the main shaft 8, and the belt 20 is sleeved on the outer sides of the driving pulley 19 and the driven pulley 42. When the second motor 18 drives the driving pulley 19 to rotate, it can rely on the belt 20 to drive the driven pulley 42 and the main shaft 8 to rotate, which can drive the tool shaft 5 to rotate, so that the end turning tool 24 can cut the mounting hole 2 of the bearing seat 1.

[0032] There are two groups of spindles 8 and clamping assemblies, which are arranged side by side on the workbench 4. The two spindles 8 are equipped with tool shafts 5, so that the two bearing seats 1 can be processed separately, one for clamping and the other for processing, thereby saving waiting time and further improving the processing efficiency of the bearing seat 1.

[0033] Working principle: When machining the mounting hole 2 of the bearing seat 1, the bearing seat 1 is positioned by the positioning column 22 on the positioning plate 21, and the pressure plate 11 is driven by the oil cylinder 9 to press the bearing seat 1. In the initial state, the cutting assembly 23 is located in the mounting groove 13, and then the first driving assembly drives the workbench 4 and the bearing seat 1 to slide horizontally and approach the knife shaft 5 until the bearing seat 1 moves to the position between the two cutting assemblies 23. At this time, the oil inlet control valve 15 is opened, and the hydraulic oil is passed into the two oil storage chambers 36 through the guide pipe 17. As the oil pressure increases, the piston plate 26 drives the movable sleeve 28 to slide under the push of the hydraulic oil, relying on the annular gear block. The meshing of gear 39 with gear 34 causes the tool holder 25 and the end face turning tool 24 to rotate 90°, and all cutting components 23 are rotated to a state perpendicular to the tool shaft 5. The distance between two different cutting components 23 in the length direction of the tool shaft 5 is greater than the thickness of the bearing seat 1. The spindle 8 is driven to rotate by the second driving component, so that the tool shaft 5 drives the end face turning tool 24 to rotate, and the first driving component drives the bearing seat 1 to move horizontally. The cutting components 23 on both sides of the bearing seat 1 complete the processing of the two mounting holes 2 in succession without the need for secondary clamping, and the two spindles 8 and tool shafts 5 can complete the processing of the two bearing seats 1, so that the processing efficiency is greatly improved.
