Description

Technical Field

[0001] This invention relates to the field of automated machining, and in particular to a high-efficiency grinding equipment for shaft parts. Background Technology

[0002] A type of bearing, such as Figure 16 As shown, the shaft includes a shaft body 7, which comprises a shaft shaft 71 and a shaft tail 72. A shaft hole is provided on the shaft shaft 71. The outer diameter of the shaft body 7 needs to be ground using grinding equipment to ensure the surface roughness of the sidewalls.

[0003] Traditional grinding equipment can only grind one shaft 7 at a time, which results in low processing efficiency. Therefore, it is necessary to develop a new type of grinding equipment that can grind two shafts 7 to improve grinding efficiency. Summary of the Invention

[0004] This application provides a high-efficiency grinding equipment for shaft parts, which can process two shafts simultaneously with high processing efficiency.

[0005] The technical solution of the high-efficiency grinding equipment for shaft parts provided in this application is as follows:

[0006] A high-efficiency grinding equipment for shaft parts includes a conveying mechanism for conveying shafts, a grinding machine, and a clamping and transporting device. The grinding machine is provided with a mounting table, on which two headstocks are slidably mounted. The mounting table is also provided with two sets of drive mechanisms for driving the headstocks to move. A fixed frame is provided on the mounting table, located between the two headstocks. Two rotating shafts are rotatably mounted on the fixed frame, symmetrically arranged on both sides of the fixed frame. Each of the two rotating shafts has a tapered head at the end away from the fixed frame, and the tapered head is used to insert into a shaft hole located on the shaft body.

[0007] The clamping and transporting device is used to clamp two shafts on the conveying mechanism and transport the two shafts to the position between the corresponding rotating shaft and the corresponding head frame, so that the axis of the two shafts coincides with the axis of the two rotating shafts; subsequently, the two head frames move closer to each other and press the two shafts against the two rotating shafts, so that the two rotating shafts are inserted into the shaft holes on the two shafts respectively.

[0008] After the shaft grinding is completed, the clamping and transporting device clamps the two shafts, and the two headstocks move in opposite directions. Then, the clamping and transporting device drives the two shafts to move away from the two rotating shafts. During this process, the cone head forces the two shafts to move relative to the clamping and transporting device along their respective length directions, thereby disengaging from the two rotating shafts.

[0009] By adopting the above technical solution, automatic feeding and clamping of two shafts can be achieved, enabling the grinding machine to process two shafts simultaneously.

[0010] Preferably, the conveying mechanism includes a housing, two rollers rotatably connected to both ends of the housing, a first motor mounted on the housing and used to drive one of the rollers to rotate, and a lifting assembly located inside the housing. Sprockets are fitted onto both ends of the two rollers, and chains are fitted onto the two sprockets on the same side. Multiple placement blocks are provided on the chains, and each placement block has a receiving groove for accommodating shafts. When multiple shafts are placed on the two chains, the shafts are arranged along the length of the housing, and the axes of the shafts are parallel. The lifting assembly is used to lift the two shafts located at the ends of the housing, facilitating the clamping and conveying device to clamp the two shafts.

[0011] By adopting the above technical solution, automatic transmission of the shaft can be achieved.

[0012] Preferably, the lifting assembly includes a mounting plate slidably disposed on the housing along the height direction of the housing, two lifting rods disposed on the mounting plate, and a cylinder disposed inside the housing for driving the mounting plate to slide; the ends of the two lifting rods away from the mounting plate are located between two chains, and two receiving grooves are provided on the ends of the two lifting rods away from the mounting plate for accommodating shafts, and the two shafts located at the end of the housing are respectively located directly above the four receiving grooves.

[0013] By adopting the above technical solution, the two shafts to be processed are raised so that the clamping and transporting device mechanism will not come into contact with other shafts when clamping the shafts.

[0014] Preferably, the clamping and transporting device includes a mounting frame, a Y-axis linear module mounted on the mounting frame, a Z-axis linear module mounted on the slider of the Y-axis linear module, a mounting base mounted on the slider of the Z-axis linear module, a first pneumatic gripper mounted on the mounting base, a second pneumatic gripper slidably mounted on the mounting base, and a control mechanism mounted on the mounting base for controlling the movement of the second pneumatic gripper; when the first pneumatic gripper and the second pneumatic gripper clamp two shafts, the axes of the two clamped shafts are parallel; after the second pneumatic gripper clamps the shafts, the control mechanism drives the second pneumatic gripper to move, and after the second pneumatic gripper stops moving, the axes of the two clamped shafts coincide.

[0015] By adopting the above technical solution, after the first starting gripper and the second pneumatic gripper clamp the two lifted shafts, the control mechanism drives the second pneumatic gripper to move, so that the shafts clamped by the second pneumatic gripper move and change position, and finally make the axes of the two shafts coincide, which facilitates material loading.

[0016] Preferably, the control mechanism includes a first lead screw rotatably mounted on a mounting base, a second motor mounted on the mounting base for driving the first lead screw to rotate, and a threaded block threadedly connected to the first lead screw. The mounting base has a sliding groove, and the threaded block is slidably mounted in the sliding groove and connected to a second pneumatic gripper.

[0017] By adopting the above technical solution, the second motor rotates to drive the first lead screw to rotate, and when the first lead screw rotates, it drives the second pneumatic gripper to slide.

[0018] Preferably, the drive mechanism includes a second lead screw rotatably mounted on the mounting platform and a third motor mounted on the mounting platform for driving the second lead screw to rotate, and the headstock is threadedly connected to the second lead screw.

[0019] By adopting the above technical solution, the rotation of the third motor controls the rotation of the second lead screw, and the rotation of the second lead screw drives the head frame to slide.

[0020] The main technical effects of this invention are reflected in the following aspects:

[0021] 1. This invention uses two frame heads to press two shafts against two rotating shafts to achieve automatic feeding of the two shafts;

[0022] 2. This invention achieves automatic displacement and unloading of two shafts through the cooperation of a cone head and a clamping and conveying device;

[0023] 3. The present invention provides a lifting component to lift the two shafts to be processed, so that the clamping and transporting device mechanism will not collide with other shafts when clamping the shafts. Attached Figure Description

Detailed Implementation

[0041] The present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this application can be more easily understood and mastered.

[0042] Reference Figures 1-3 This embodiment of a high-efficiency grinding equipment for shaft parts includes a conveying mechanism 1 for conveying shaft 7, a grinding machine 2, and a clamping and transporting device 3. The conveying mechanism 1 includes a housing 11, two rollers 12 rotatably connected to both ends of the housing 11, and a first motor 13 mounted on the housing 11 for driving one of the rollers 12 to rotate.

[0043] Reference Figures 1-4 Both ends of the two rotating rollers 12 are fitted with sprockets 14, and chains 15 are fitted on the two sprockets 14 on the same side. Each chain 15 has multiple placement blocks 16, and each placement block 16 has a receiving groove 17 for accommodating the shaft 7. When the shaft 7 is placed on the two chains 15, the shaft body 71 and the shaft tail 72 should be placed in the corresponding receiving grooves 17 of the two chains 15 respectively. When multiple shafts 7 are placed on two chains 15, the multiple shafts 7 are arranged along the length of the housing 11 and the axes of the multiple shafts 7 are all parallel.

[0044] Reference Figure 2 and Figure 3 When the first motor 13 starts, it drives one of the rollers 12 to rotate. The rotation of the roller 12 drives the sprockets 14 sleeved on both ends to rotate. The rotation of the sprockets 14 drives the two chains 15 to transmit power. The two chains 15 drive the shaft 7 to transmit power along the length of the housing 11.

[0045] Reference Figures 1-4 The conveying mechanism 1 also includes a lifting assembly 5, which is used to lift the two shafts 7 located at the end of the housing 11, facilitating the clamping and transporting device 3 to clamp the two shafts 7. The lifting assembly 5 includes a mounting plate 51 slidably mounted on the housing 11 along its height direction, two lifting rods 52 mounted on the mounting plate 51, and a cylinder 53 located inside the housing 11 for driving the mounting plate 51 to slide. The mounting plate 51 is connected to the piston rod of the cylinder 53. When the two lifting rods 52 are not raised, the ends of the two lifting rods 52 away from the mounting plate 51 are located between the two chains 15. Each end of the two lifting rods 52 away from the mounting plate 51 has two receiving grooves 54 for accommodating the shafts 7. The spacing between the two receiving grooves 54 on the same lifting rod is adapted to the support spacing of the shafts 7 on the chains. When the two shafts 7 to be processed are conveyed to the end of the housing 11, these two shafts 7 are located directly above the two lifting rods 52, and the two receiving slots 54 on each lifting rod 52 are directly below the two shafts 7 to be processed. In this embodiment, the end of the housing 11 refers to the end near the grinding machine 2.

[0046] Reference Figure 1 and Figure 5 The grinding machine 2 is equipped with a mounting table 21, on which two headstocks 22 are slidably mounted along the Y-axis. The mounting table 21 also has two sets of drive mechanisms 4 for driving the headstocks 22. Each drive mechanism 4 includes a second lead screw 41 rotatably mounted on the mounting table 21 and a third motor 42 mounted on the mounting table 21 for driving the second lead screw 41. The two headstocks 22 are threadedly connected to the two second lead screws 41. (The headstock 22 is a well-known component in the field of grinding machines 2, and its internal structure is not described in this embodiment.)

[0047] Reference Figure 1 , Figure 5 and Figure 6 A mounting platform 21 is equipped with a fixing frame 23, which is located between two head frames 22. Two rotating shafts 24 are rotatably mounted on the fixing frame 23, and the two rotating shafts 24 are symmetrically arranged on both sides of the fixing frame 23. Each of the two rotating shafts 24 has a conical head 25 at the end away from the fixing frame 23, which is used to insert into the shaft hole of the shaft body 7.

[0048] Reference Figure 1 , Figure 4 , Figures 7-9 The clamping and transporting device 3 is used to clamp the two shafts 7 on the conveying mechanism 1 and transport the two shafts 7 to the positions between the corresponding rotating shaft 24 and the corresponding headstock 22, so that the axes of the two shafts 7 coincide with the axes of the two rotating shafts 24. The clamping and transporting device 3 includes a mounting frame 31, a Y-axis linear module 32 mounted on the mounting frame 31, a Z-axis linear module 33 mounted on the slider of the Y-axis linear module 32, a mounting base 34 mounted on the slider of the Z-axis linear module 33, a first pneumatic gripper 35 mounted on the mounting base 34, and a second pneumatic gripper 36 slidably mounted on the mounting base 34. The Y-axis linear module 32 is located at the end of the housing 11 and above the grinding machine 2.

[0049] Reference Figure 7 and Figure 8 The Y-axis linear module 32 includes a first slide 321 slidably connected to a mounting bracket 31 along the Y-axis direction, a rack 322 mounted on the mounting bracket 31, a fourth motor 323 mounted on the first slide 321, and a gear 324 mounted on the shaft 24 of the fourth motor 323. The gear 324 meshes with the rack 322, and the fourth motor 323 is a servo motor. When the fourth motor 323 starts, it drives the gear 324 to rotate, and when the gear 324 rotates, it drives the first slide 321 to slide on the mounting bracket 31.

[0050] Reference Figure 7 and Figure 8The Z-axis linear module 33 includes a second slide 331 slidably connected to a first slide 321 along the Z-axis direction, a rack 332 mounted on the second slide 331, a fifth motor 333 mounted on the first slide 321, and a gear 334 mounted on the shaft 24 of the fifth motor 333. The gear 334 meshes with the rack 332. The fifth motor 333 is a servo motor. When the fifth motor 333 starts, it drives the gear 334 to rotate. When the gear 334 rotates, it drives the second slide 331 to slide on the first slide 321. A mounting base 34 is located at the bottom end of the second slide 331.

[0051] Reference Figure 9 and Figure 10 The clamping and transporting device 3 also includes a control mechanism 6 mounted on the mounting base 34 for controlling the movement of the second pneumatic gripper 36. The control mechanism 6 includes a first lead screw 61 rotatably mounted on the mounting base 34, a second motor 62 mounted on the mounting base 34 for driving the first lead screw 61 to rotate, and a threaded block 63 threadedly connected to the first lead screw 61. A groove 37 is provided on the mounting base 34, and the threaded block 63 is slidably disposed within the groove 37 along the axial direction of the first lead screw 61. The bottom of the threaded block 63 is connected to the second pneumatic gripper 36.

[0052] Reference Figure 4 , Figure 9 and Figure 11 When the first pneumatic gripper 35 and the second pneumatic gripper 36 clamp two shafts 7, the axes of the two clamped shafts 7 are parallel. After the second pneumatic gripper 36 clamps the shafts 7, the second motor 62 starts and drives the first lead screw 61 to rotate, thereby causing the second pneumatic gripper 36 to slide until the axes of the two clamped shafts 7 coincide.

[0053] Reference Figure 1 A conveyor 8 is placed between the grinding machine 2 and the housing 11. The shaft 7 that has been ground on the outer diameter will be placed on the conveyor 8 and then transported away.

[0054] Reference Figures 1-15 The complete processing technology of the equipment in this application is as follows:

[0055] First, the technicians place multiple shafts 7 on two chains 15. Two shafts 7 to be processed in the same group are placed side by side on the chains 15, with opposite orientations, so that the shaft body 71 of one shaft corresponds to the shaft tail 72 of the other. This placement ensures that after the second pneumatic gripper 36 clamps and moves the shaft 7, the two shaft holes 73 on the two shafts 7 being processed in the same group can be aligned.

[0056] After the shaft 7 is in place, the fourth motor 323 starts rotating forward, driving the first slide 321 to slide, so that the mounting base 34 moves to above the end of the housing 11. Then the piston rod of the cylinder 53 extends, driving the mounting plate 51 and the two lifting rods 52 to move upward. When the two lifting rods 52 move upward, they will lift the two shafts 7. Then the fifth motor 333 starts rotating forward, driving the second slide 331 and the mounting base 34 to move downward.

[0057] After the mounting base 34 stops moving, the two lifted shafts 7 are positioned between the jaws of the first pneumatic gripper 35 and the second pneumatic gripper 36, respectively. Then, the first pneumatic gripper 35 and the second pneumatic gripper 36 clamp the two shafts 7. When clamped, the two shafts 7 can move relative to the first pneumatic gripper 35 and the second pneumatic gripper 36 along their respective axial directions.

[0058] Then, the fifth motor 333 reverses to drive the mounting base 34 upwards, followed by the fourth motor 323 reversing to drive the mounting base 34 laterally above the grinding machine 2. Next, the second motor 62 starts, driving the first lead screw 61 to rotate forward, causing the second pneumatic gripper 36 to slide, thus changing the position of the shaft 7 held by the second pneumatic gripper 36, aligning the axes of the two gripped shafts 7, and positioning the two tails 72 of the two gripped shafts 7 opposite each other. Then, the fifth motor 333 rotates forward to drive the mounting base 34 downwards, moving the two shafts 7 between the two headstocks 22 and the two rotating shafts 24, aligning the axes of the two shafts 7 with the axes of the two rotating shafts 24, and positioning the two tails 72 of the two shafts 7 directly opposite the two rotating shafts 24.

[0059] Then, the two third motors 42 are started to make the two second lead screws 41 rotate forward, thereby driving the two head frames 22 to move closer to each other. During this process, the shaft heads of the two shafts 7 are first inserted into the two head frames 22 respectively. Then, the two head frames 22 push the two shafts 7 to move closer to each other, that is, the two shafts 7 move relative to the first pneumatic gripper 35 and the second pneumatic gripper 36. Finally, the two shafts 7 are pressed onto the two rotating shafts 24 by the two head frames 22, and the two cones 25 are inserted into the shaft holes on the shaft tails 72 of the two shafts 7 respectively.

[0060] Then the first pneumatic gripper 35 and the second pneumatic gripper 36 open, releasing the grip on the two shafts 7. Next, the fifth motor 333 reverses and drives the mounting base 34 to move upward, so that the first pneumatic gripper 35 and the second pneumatic gripper 36 move out of the grinding machine 2.

[0061] Then, the two headstocks 22 drive the two shafts 7 to rotate, and the two grinding wheels on the grinding machine 2 grind the outer diameter of the two shafts 7. After the two shafts 7 are ground, the two grinding wheels retract, and the two headstocks 22 stop rotating. The fifth motor 333 rotates forward to drive the mounting base 34 to move downward, so that the two machined shafts 7 are respectively positioned between the chucks of the first pneumatic gripper 35 and the second pneumatic gripper 36. Then, the first pneumatic gripper 35 and the second pneumatic gripper 36 clamp the two shafts 7.

[0062] Next, the two third motors 42 start to reverse the two second lead screws 41, thereby driving the two headstocks 22 to move away from each other and disconnect them from the two shafts 7. Then, the fifth motor 333 rotates forward to drive the mounting base 34 to move upward. During this process, the first pneumatic gripper 35 and the second pneumatic gripper 36 drive the two shafts 7 to move upward. During the upward movement of the two shafts 7, the two cones 25 force the two shafts 7 to move relative to the first pneumatic gripper 35 and the second pneumatic gripper 36 along their respective length directions, thereby disengaging from the two rotating shafts 24.

[0063] Next, the second motor 62 starts and drives the first lead screw 61 to reverse, causing the second pneumatic gripper 36 to slide and reset, thus changing the position of the shaft 7 held by the second pneumatic gripper 36. This makes the axes of the two gripped shafts 7 parallel. Then, the fourth motor 323 rotates forward and drives the mounting base 34 to move above the conveyor 8. Then, the fifth motor 333 rotates forward and drives the mounting base 34 to move downward. After the mounting base 34 stops moving downward, the first pneumatic gripper 35 and the second pneumatic gripper 36 release their grip on the two shafts 7, allowing the two shafts 7 to fall onto the conveyor belt of the conveyor 8.

[0064] During the process of placing the two machined shafts 7 onto the conveyor 8, the piston rod of cylinder 53 retracts, driving the mounting plate 51 and the two lifting rods 52 to move downwards and reset. Then, the first motor 13 starts, driving the two chains 15 to move, so that the two new shafts 7 to be machined move above the two receiving slots 54. Then, the piston rod of cylinder 53 extends, driving the mounting plate 51 and the two lifting rods 52 upwards.

[0065] After the two machined shafts 7 are placed on the conveyor 8, the Y-axis linear module 32 and the Z-axis linear module 33 start to drive the mounting base 34 to move, so that the first pneumatic gripper 35 and the second pneumatic gripper 36 clamp the two new shafts 7. Then, the above steps are repeated to transport the two shafts 7 to the grinding machine 2 to start the machining of the two new shafts 7.

[0066] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
