[0036] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0037] refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a rotary table surface grinder, comprising a machine body 1 and a grinding assembly 2 disposed on the machine body 1. The grinding assembly 2 is used to grind the workpiece to be ground. It also includes a rotary working mechanism 3 and a linear working mechanism 4. The rotary working platform is disposed below the grinding assembly 2. The rotary working mechanism 3 is used to fix the workpiece to be ground and enable the workpiece to be ground to rotate circumferentially. The linear working mechanism 4 is used to drive the rotary working mechanism 3 to achieve reciprocating movement in the horizontal direction.
[0038] refer to Figure 1 , Figure 2 and Figure 3The rotary working mechanism 3 includes a support base 31, a rotary table 33 rotatably connected to the support base 31 via a rotating component 32, and a driving component 34 that drives the rotary table 33 to rotate. The rotary table 33 is located below the grinding assembly 2. The rotary table 33 is used to fix the workpiece to be ground and to make the workpiece to be ground rotate circumferentially. The rotary table 33 is a magnetic rotary table 33. The workpiece to be ground is magnetically attracted to the rotary table 33. The workpiece to be ground is a disc-type workpiece, such as an eccentric disc.
[0039] refer to Figure 1 , Figure 2 and Figure 3 The rotating component 32 includes a frustum mold base 321 and a main shaft 322 mounted on a support base 31. The main shaft 322 is rotatably connected to the frustum mold base 321 via a bearing assembly 323. The upper end face of the main shaft 322 is flush with the upper end face of the frustum mold base 321. The rotary table 33 is detachably connected to the upper end face of the main shaft 322 via bolts.
[0040] refer to Figure 1 , Figure 2 and Figure 3 The drive unit 34 is located on one side of the rotary table 33. The drive unit 34 includes a geared motor 341, a synchronous pulley I 342, a synchronous pulley II 343, and a synchronous belt 344 connecting the synchronous pulley I 342 and the synchronous pulley II 343. The geared motor 341 is inverted on the support base 31, and the drive shaft of the geared motor 341 rotates through the support base 31. The synchronous belt 344 pulley I 342 is located on the drive shaft of the geared motor 341. The bottom end of the main shaft 322 rotates through the support base 31, and the synchronous pulley II 343 is sleeved on the bottom of the main shaft 322.
[0041] refer to Figure 1 , Figure 2 and Figure 3 The upper end face of the frustum mold base 321 is provided with an O-ring groove, and a sealing ring 5 is embedded in the O-ring groove. The horizontal length of the rotary table 33 is greater than the horizontal length of the frustum mold base 321. When the rotary table 33 is installed on the upper end face of the spindle 322, the lower end face of the rotary table 33 presses against the upper end face of the frustum mold base 321. At this time, the sealing ring 5 plays a sealing role to prevent the cutting fluid from entering the interior of the frustum mold base 321 when grinding disc-shaped workpieces.
[0042] refer to Figure 1 , Figure 2 and Figure 3 When the rotary working mechanism 3 is working, the workpiece to be ground is magnetically attracted on the rotary table 33, and the driving component 34 drives the rotary table 33 to rotate circumferentially. At the same time, the grinding component 2 works to realize circumferential grinding of the workpiece to be ground.
[0043] refer to Figure 1 , Figure 2and Figure 3 The linear working mechanism 4 includes a support base 41, a ball screw assembly 42, a drive motor 43 that drives the ball screw assembly 42, and a sliding plate 44. The support base 41 has an opening at its upper end, and the ball screw assembly 42 is rotatably connected within the opening 6. The support base 41 also has a placement cavity 7 for housing the drive motor 43. One end of the screw in the ball screw assembly 42 extends into the placement cavity 7 and connects to the rotation shaft of the drive motor 43. The bottom end of the sliding plate 44 is connected to the balls in the ball screw assembly 42. A support base 31 is fixed to the upper surface of the sliding plate 44. The upper surface of the support base 41 has at least one guide protrusion 8, and the lower surface of the sliding plate 44 has a guide groove 9 that mates with the guide protrusion 8. If there are two guide protrusions 8, then there are also two guide grooves 9 on the lower surface of the sliding plate 44. The two guide grooves 9 are located on opposite sides of the width of the lower surface of the sliding plate 44. The stability of the sliding plate 44 is ensured by the cooperation between the guide protrusion 8 and the guide groove 9.
[0044] refer to Figure 1 , Figure 2 and Figure 3 When the product to be ground needs to be linearly ground, the drive motor 43 drives the screw in the ball screw assembly 42 to rotate, thereby causing the balls in the ball screw assembly 42 to move along the length of the screw, which in turn drives the rotary worktable set on the sliding plate 44 to move linearly. At this time, it cooperates with the grinding assembly 2 to realize the linear grinding of the grinding assembly 2.
[0045] In summary, this rotary table surface grinder integrates circumferential and linear grinding into one unit, enabling both circumferential and linear grinding of the workpiece. When switching between circumferential and linear grinding, the product does not need to be removed, allowing for continuous processing and thus improving processing efficiency. It also reduces the amount of equipment required, saving costs. Furthermore, it reduces the number of personnel needed, saving on labor costs.
