In the production process, the grinding of the solid shaft is crucial. It not only affects the appearance quality of the shaft, but is also directly related to the wear resistance, corrosion resistance and service life of the shaft. The traditional solid shaft grinding method mainly relies on manual operation, such as grinding with a handheld grinding wheel. This method has problems such as low production efficiency due to differences in workers' experience. With the development of automated grinding equipment, advanced CNC technology and precise mechanical structure have been used to greatly improve production efficiency and product quality.

[0003] However, the existing grinding equipment still has some limitations in its design. For example, a single device can only grind a single real shaft during grinding, which leads to low efficiency.

DETAILED DESCRIPTION

[0018] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Reference Figure 1 and Figure 2 The present invention provides a grinding device for solid shaft production, comprising a rotating power machine base 1 and a fixed base 3. A plurality of rotating clamping arms 2 are rotatably sleeved on one side of the rotating power machine base 1. The plurality of rotating clamping arms 2 are distributed in a ring shape along the output shaft of the rotating power machine base 1. The output shaft of the rotating power machine base 1 is connected to the rotating clamping arms 2 through a transmission mechanism 2 6. A plurality of pressing clamp arms 4 are installed inside the fixed seat 3, and the output ends of the plurality of pressing clamp arms 4 are respectively aligned with the plurality of rotating clamp arms 2 in transverse direction. The rotating clamp arms 2 and the pressing clamp arms 4 are used to clamp the real shaft a of the grinding piece and realize self-centering and anti-slipping. A grinding mechanism 5 is installed on the side of the fixed seat 3 facing the rotating power machine base 1, and the other end of the grinding mechanism 5 is connected to the output shaft of the rotating power machine base 1. The rotating power machine base 1 drives the grinding mechanism 5 to rotate for grinding the surfaces of the plurality of real shafts a; The grinding mechanism 5 rotates to realize self-propelled axial grinding along the real axis a, and the transmission mechanism 2 6 is used to transmit the torque of the rotating power machine base 1 to make the plurality of rotating clamping arms 2 rotate in different directions, so as to realize the circumferential grinding of the real axis a by the grinding mechanism 5.

[0020] When in use, the real shafts a of the grinding parts can be clamped and fixed by the plurality of rotating clamp arms 2 and the pressing clamp arms 4, and the power output by the rotating power machine base 1 drives the grinding mechanism 5 to rotate at high speed, and contacts with the plurality of real shafts a on the circumferential side for grinding. In this process, the rotating force of the rotating power machine base 1 drives the plurality of rotating clamp arms 2 to rotate in opposite directions through the transmission mechanism 2 6, and the friction force of the rotating clamp arms 2 in contact with the end faces of the real shaft a can make the rotating clamp arms 2 reach the real shaft a for rotation. At this time, the circumferential surfaces of the plurality of real shafts a can be contacted with the grinding mechanism 5 to realize circumferential grinding, and the grinding mechanism 5 is driven by the rotating power machine base 1 to rotate at high speed to perform self-propelled grinding along the axial direction of the real shaft a, thereby enabling the equipment to realize multi-station processing and improve the processing efficiency of the real shaft grinding process. In addition, a single power can be used to realize the circumferential and axial grinding requirements of the real shaft a, which is suitable for the grinding processing of shafts, columns and pipes.

[0021] Reference Figure 3 The grinding mechanism 5 includes an end block 51 and a rotary column 52. Two threaded shafts 53 are rotatably sleeved on the inner sides of the end block 51 and the rotary column 52. A grinding disc 54 is threadedly sleeved on the side walls of the two threaded shafts 53. The end block 51 is fixedly connected to the end face of the output shaft of the rotating power machine base 1. A fixed disc 56 is rotatably sleeved on the side wall of the rotary column 52. A transmission mechanism 55 is fixedly connected to one side of the fixed disc 56. The fixed disc 56 is fixedly installed on one side of the fixed base 3. The rotary column 52 is transmission-connected to the two threaded shafts 53 through the transmission mechanism 55. The transmission mechanism 55 is used to transmit the torque of the rotary column 52 to rotate the two threaded shafts 53.

[0022] Through the connection relationship between the end block 51, the rotary column 52, and the threaded shaft 53, when the rotary power base 1 outputs rotary power, the two threaded shafts 53 can be made to revolve. At this time, the revolution of the two threaded shafts 53 can make the grinding disc 54 rotate at high speed to grind the real shaft a. In this process, the rotational force of the rotary column 52 is transmitted through the transmission mechanism 55, so that the two threaded shafts 53 revolve and rotate at the same time. Due to the threaded connection relationship between the threaded shaft 53 and the grinding disc 54, the grinding disc 54 can be displaced laterally, thereby realizing grinding along the axial direction of the real shaft a.

[0023] Reference Figure 4 , the transmission mechanism 1 55 includes a fixed shell 551 and a fixed arm plate 552. The fixed shell 551 is fixedly connected to one side of the grinding disc 54, and the fixed arm plate 552 is fixedly connected to the end face of the rotating column 1 52. One side of the fixed arm plate 552 is rotatably connected with two active side columns 553, and one end of the two active side columns 553 is fixedly connected with a gear 1 554. The inner wall of the fixed shell 551 is fixedly connected with a fixed gear 555. The fixed gear 555 is located at the gap between the two gears 1 554 and meshes with the two gears 1 554. One side of the fixed arm plate 552 is also rotatably connected with two driven side columns 556. One end of the two driven side columns 556 is fixedly connected with a gear 3 558, and the other end passes through the fixed arm plate 552, the rotating column 1 52 and is connected to the two threaded shafts 53. The side walls of the two active side columns 553 are fixedly connected with gears 2 557, and the two gears 2 557 are respectively meshed with the two gears 3 558; The number of teeth of gear one 554 is greater than the number of teeth of fixed gear 555 , and the number of teeth of gear three 558 is greater than the number of teeth of gear two 557 .

[0024] When the rotating column 1 52 rotates, it drives the two active side columns 553 to revolve, and the two active side columns 553 revolve to make the two gears 1 554 roll on the side wall of the fixed gear 555. Because the gear 1 554 is meshing with the fixed gear 555, the gear 1 554 rotates along the side wall of the fixed gear 555. At this time, the two active side columns 553 are driven to rotate by the two gears 1 554. The meshing relationship between the gear 2 557 and the gear 3 558 makes the two active side columns 553 rotate. The two driven side columns 556 are driven to rotate, and the two threaded shafts 53 are rotated by the rotation of the two driven side columns 556, thereby realizing the transmission effect of the transmission mechanism 1 55; in this process, the transmission deceleration effect can be achieved through the difference in the number of teeth between the gear 1 554 and the fixed gear 555, and the deceleration transmission is performed again through the difference in the number of teeth between the gear 2 557 and the gear 3 558. This setting can greatly reduce the rotation speed of the two threaded shafts 53, avoiding the situation that the lateral movement speed of the grinding disk 54 is too fast, resulting in incomplete circumferential grinding of the real axis a.

[0025] Reference Figure 5The grinding disc 54 includes a middle disc 541, and a plurality of side grooves 542 are opened on the periphery of the middle disc 541. A plurality of grinding contacts 543 are slidably sleeved inside the plurality of side grooves 542. The side walls of the plurality of grinding contacts 543 are fixedly connected with T-shaped sliders 545. The inner walls of the plurality of side grooves 542 are opened with T-shaped slide grooves, and the T-shaped slide grooves 545 are slidably sleeved in the T-shaped slide grooves. A threaded hole is opened on one side of the grinding contact 543 and penetrates to the other side of the T-shaped slide groove, and a threaded rod 546 is threadedly sleeved in the threaded hole.

[0026] Since the diameter of the real axis a of the grinding piece will affect the distance from its side wall to the grinding disc 54, the structure of the grinding disc 54 is optimized, and grinding is performed by contacting the real axis a with a plurality of grinding contacts 543. The grinding contacts 543 are slidable in the side grooves 542, so that the distance between the grinding end of the grinding disc 54 and the grinding piece can be adjusted, so that the device can match shaft grinding pieces of more diameters. The threaded rod 546 is used to tighten the position of the grinding contact 543 in the side grooves 542, and the T-shaped slider 545 prevents the grinding contact 543 from falling off.

[0027] Reference Figure 5 A frosted pad 544 is fixedly connected to one end of the threaded rod 546 toward the T-shaped slot. When the threaded rod 546 is rotated to press against the inner wall of the T-shaped slot to tighten the position of the grinding contact 543, the frosted pad 544 contacts the inner wall of the T-shaped slot to increase the friction force, so that the position of the grinding contact 543 can be locked more tightly.

[0028] Reference Figure 6 The transmission mechanism 2 6 includes a central gear 61, a plurality of planetary gears 62, a retainer 63, and a plurality of rotary pillars 2 64. The retainer 63 is fixedly connected to the inner wall of the rotating power machine base 1, and the retainer 63 is movably sleeved on the side wall of the output shaft of the rotating power machine base 1. The central gear 61 is fixedly connected to the side wall of the output shaft of the rotating power machine base 1, and a plurality of rotary pillars 2 64 are rotatably sleeved on one side of the retainer 63. A plurality of planetary gears 62 are fixedly connected to the side walls of the plurality of rotary pillars 2 64. A plurality of planetary gears 62 are meshed with the central gear 61, and one end of a plurality of rotating clamping arms 2 away from the fixed base 3 is respectively connected to the plurality of rotary pillars 2 64.

[0029] When the rotary power base 1 outputs a rotational force, it drives the central gear 61 to rotate. Through the meshing relationship between the central gear 61 and the rotary column 64, the central gear 61 can drive several planetary gears 62 to rotate in opposite directions, and the rotary column 64 is driven to rotate by the planetary gears 62. Due to the connection relationship between the rotating clamping arm 2 and the rotary column 64, the transmission effect of the transmission mechanism 2 6 is realized, so that several rotating clamping arms 2 rotate in opposite directions.

[0030] Reference Figure 7The pressing clamp arm 4 is composed of an electric cylinder 41 and a movable clamp 42. The movable clamp 42 is rotatably sleeved at the output end of the electric cylinder 41. The rotating clamp arm 2 is composed of a main rotating arm 21 and a fixed clamp 22. The fixed clamp 22 is fixedly connected at one end of the main rotating arm 21.

[0031] The movable chuck 42 is displaced by the output of the electric cylinder 41, so that the distance between the movable chuck 42 and the fixed chuck 22 is reduced, and the grinding piece a is placed between the fixed chuck 22 and the movable chuck 42. The fixed chuck 22 and the movable chuck 42 are pressed against the two ends of the solid shaft a to achieve a clamping effect. When the real shaft a is driven to rotate by rotating the clamp arm 2, the movable chuck 42 rotates on the output shaft of the electric cylinder 41 to avoid affecting the electric cylinder 41. The electric cylinder 41 is not the only implementation method and can be replaced by a pneumatic cylinder, an oil cylinder or a threaded telescopic mechanism.

[0032] Reference Figure 7 The inner sides of the fixed chuck 22 and the movable chuck 42 are both provided with conical grooves.

[0033] Through this arrangement, when the fixed chuck 22 and the movable chuck 42 are close to and pressed against the two ends of the real shaft a, the two ends of the real shaft a enter into the conical grooves of the fixed chuck 22 and the movable chuck 42. According to the characteristics of the conical grooves, the two ends of the real shaft a can be centered to ensure that the real shaft a is parallel to the grinding mechanism 5 after being fixed. In addition, it can also prevent the real shaft a from being separated from between the fixed chuck 22 and the movable chuck 42 when being subjected to force during grinding.

[0034] Reference Figure 8 A positioning ring 421 is provided on the inner wall of the dynamic chuck 42, and an annular groove is provided on the side wall of the output shaft of the electric cylinder 41. The positioning ring 421 is embedded in the annular groove. A plurality of balls 422 distributed in an annular shape are provided on the inner wall of the dynamic chuck 42 facing the end face of the output shaft of the electric cylinder 41. The plurality of balls 422 are in contact with the end face of the output shaft of the electric cylinder 41.

[0035] By setting a positioning ring 421 and cooperating with the annular groove on the output shaft of the electric cylinder 41, the movable chuck 42 can be prevented from falling off. When the equipment is grinding, the rotating clamp arm 2 will drive the real shaft a to rotate. When the movable chuck 42 and the fixed chuck 22 are pressed against the end face of the real shaft a, the movable chuck 42 will be subjected to a reverse force and a large friction force generated by the electric cylinder 41, which affects its rotation. By setting a plurality of ball bearings 422, the rotational friction force of the movable chuck 42 can be greatly reduced.

[0036] Reference Fig. 9An axial hole 221 connected to the conical groove of the main rotating arm 21 is provided inside the fixed chuck 22, an outer cylinder 222 is slidably sleeved inside the axial hole 221, a threaded inner column 223 is threadedly sleeved on the inner wall of the outer cylinder 222, a knob 224 is provided on the side wall of the fixed chuck 22 that penetrates into the axial hole 221, an output end of the knob 224 is transmission-connected to one end of the threaded inner column 223 through a bevel gear transmission group 225, and a frosted pad 226 is fixedly connected to one end of the outer cylinder 222 that enters the conical groove.

[0037] Since the rotating clamp arm 2 needs to drive the real shaft a to rotate through friction, through the structural setting of the fixed clamp head 22, when one end of the real shaft a enters the conical groove of the main rotating arm 21, the threaded inner column 223 is rotated by rotating the knob 224 under the transmission effect of the bevel gear transmission group 225, and the outer cylinder 222 can be displaced according to the thread relationship, driving the frosted pad 226 to press against the end face of the real shaft a, thereby increasing the friction force to prevent slipping. A positioning strip is set on the side wall of the outer cylinder 222, and a positioning groove that fits with the positioning strip is set on the inner wall of the shaft hole 221, which can avoid the inability to move due to the friction force following the rotation of the threaded inner column 223.

The above embodiments and descriptions are only for explaining the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
