Technical Field
[0001] This utility model relates to the field of grinding technology, and in particular to a rotating table structure for a frustum surface grinder. Background Technology
[0002] Grinding machines are one of the most common pieces of equipment in machining centers. They consist of a worktable that holds the workpiece in place and cutting tools that grind the workpiece. Vertical grinding machines typically use a rotary table with an electromagnetic chuck to hold the workpiece in place. The rotary table rotates the workpiece, and the cutting tools perform the corresponding machining operations on the workpiece.
[0003] In existing technologies, such as the rotary table of a rotary surface grinder disclosed in Chinese Patent Publication No. CN221911103U, problems such as poor stability, large overall size, complex assembly, and difficulty in controlling precision are solved. This rotary table of a rotary surface grinder includes a base, on which a rotating stage is mounted. The base and the rotating stage are axially limited and circumferentially rotated. An electromagnetic chuck is mounted on the rotating stage, and an electromagnetic chuck power supply assembly connected to the electromagnetic chuck is mounted on the base. A stator module is mounted on the base, and a rotor module that cooperates with the stator module is mounted on the rotating stage. The rotation of the rotating stage is directly driven by the stator and rotor modules, achieving good stability, simple assembly, small size, and precise and rapid rotation control.
[0004] When a workpiece is processed by a grinding machine, it needs to be placed on the worktable first, and then the grinding mechanism grinds the workpiece on the worktable. However, the position of the worktable is fixed, which means that when the workpiece on the top of the worktable needs to be changed for grinding, the workpiece needs to be disassembled and then fixed again, which leads to the problem of cumbersome workpiece repositioning. Therefore, a rotating worktable structure for a rotary table surface grinder is needed to solve this problem. Utility Model Content
[0005] The purpose of this invention is to provide a rotating worktable structure for a frustum surface grinder, which enables the worktable to rotate.

[0012] A further feature of this invention is that the L-plate is internally threaded with a screw, and a pressure block is rotatably connected to the bottom of the screw.
[0013] By adopting the above technical solution, after the workpiece is placed on the top of the worktable, the screw is rotated, causing the screw to move inside the L-plate. The screw drives the pressure block to move, and the pressure block applies pressure to the workpiece, thereby fixing the workpiece above the worktable.
[0014] A further feature of this invention is that an anti-slip layer is fixedly connected to the bottom of the pressure block, and an anti-slip protrusion is fixedly connected to the outside of the anti-slip layer.
[0015] By adopting the above technical solution, the anti-slip layer and the anti-slip pad respectively contact both sides of the workpiece, and the friction is increased by the anti-slip layer and the anti-slip pad to prevent the workpiece from shifting during the grinding process.
[0016] A further feature of this invention is that the number of pressing blocks is four, and the four pressing blocks are distributed in a circular array.
[0017] By adopting the above technical solution, four pressure blocks are distributed in four directions on the top of the worktable, which can clamp the workpiece in four directions and have high clamping stability.
[0018] A further feature of this invention is that the number of screws is four, and each of the four screws has a handle fixedly connected to its top.
[0019] By adopting the above technical solution, the four screws are rotatably connected inside the four L-plates, and it is convenient to rotate the screws by holding the handle.
[0020] A further feature of this invention is that a motor frame is fixedly connected to the outside of the support plate, and the motor is fixedly connected to the inside of the motor frame.
[0021] By adopting the above technical solution, the motor is fixed to the outside of the support plate by the motor frame, which improves the stability of the motor during operation.
[0022] A further feature of this invention is that the internal thread of the support plate is connected to a bolt, and an anti-slip pad is sleeved on the middle of the bolt.
[0023] By adopting the above technical solution, the bolts are threaded into the interior of the support plate, so that the bolts extend into the base surface, thereby fixing the support plate and the shell to the base surface.
[0024] A further feature of this invention is that the number of bolts is eight, and the eight bolts are divided into four groups.
[0025] By adopting the above technical solution, there are four support plates, which are distributed around the bottom of the shell. Each support plate has two bolts connected to its internal thread.
[0026] The beneficial effects of this utility model are:
[0027] 1. This utility model, through the arrangement of a shell, support plate, bearing shell, bearing, worktable, motor, gear, gear disk, circular track, ring, and casters, allows the worktable to rotate within the shell via a bearing. When grinding a workpiece, the workpiece is placed on top of the worktable. When repositioning the workpiece, the motor is activated, driving the gear to rotate. The gear disk is fixed in a groove inside the worktable, and the gear meshes with the gear disk. The motor drives the gear and gear disk to mesh, allowing the worktable to rotate within the bearing. This enables the repositioning of the workpiece on top of the worktable, allowing for automatic workpiece adjustment during grinding, improving grinding efficiency and convenience. The middle of the worktable is supported by casters that extend into and slide within the circular track. When the worktable rotates, the casters travel within the circular track, ensuring stability during rotation.
[0028] 2. This utility model, through the arrangement of anti-slip pads, mounting blocks, L-plates, screws, pressure blocks, and anti-slip layers, allows the workpiece to be fixed above the worktable after it is placed on the top of the worktable. Rotating the screw causes it to move within the L-plate, which in turn moves the pressure blocks, applying pressure to the workpiece. The anti-slip layer and anti-slip pads contact both sides of the workpiece, increasing friction and preventing workpiece displacement during grinding. Four pressure blocks are distributed at the four positions on the top of the worktable, providing clamping stability to the workpiece from all four directions. Attached Figure Description

The middle of the worktable 5 is supported by casters 11. Extending into and slidingly connected to the circular track 9, the caster wheel 11 moves within the circular track 9 when the worktable 5 rotates, ensuring stability during rotation. An anti-slip pad 12 is fixedly connected to the top of the worktable 5, with anti-slip particles on its exterior. The anti-slip pad 12 and anti-slip particles increase friction, preventing workpiece displacement during grinding. A mounting block 13 is fixedly connected to the top edge of the anti-slip pad 12, and four L-plates 14 are fixedly connected to the top of the mounting blocks 13. These four L-plates 14 are fixed above the four mounting blocks 13. A screw 15 is threaded into the interior of each L-plate 14, and a pressure block 16 is rotatably connected to the bottom of the screw 15. When the workpiece... After being placed on top of the worktable 5, the screw 15 is rotated, causing it to move inside the L-plate 14. The screw 15 drives the pressure block 16 to move, applying pressure to the workpiece and thus fixing it above the worktable 5. An anti-slip layer 17 is fixedly connected to the bottom of the pressure block 16, and anti-slip protrusions are fixedly connected to the outside of the anti-slip layer 17. The anti-slip layer 17 and the anti-slip pad 12 contact both sides of the workpiece, increasing friction and preventing the workpiece from shifting during grinding.

The screw 15 drives the pressure block 16 to move, and the pressure block 16 applies pressure to the workpiece, thereby fixing the workpiece above the worktable 5. The anti-slip layer 17 and the anti-slip pad 12 contact the two sides of the workpiece respectively, and the anti-slip layer 17 and the anti-slip pad 12 increase the friction and prevent the workpiece from shifting during grinding. The four pressure blocks 16 are distributed in the four directions on the top of the worktable 5, thereby forming a clamping effect on the workpiece in four directions, and the clamping stability is high.
