Description

Technical Field

[0001] This utility model relates to the field of lathe equipment technology, specifically to a rotary worktable for a cutting and grinding machine for fused alumina bricks. Background Technology

[0002] With the rapid development and upgrading of the manufacturing industry, and the continuous progress and innovation of CNC machine tool technology, the market demand for rotary worktables for machining continues to increase. Among them, the demand for rotary worktables in the field of machining fused alumina bricks is more urgent. Because fused alumina bricks are relatively hard, machining them takes a long time, and the clamping stability of the worktable is required to be high. Moreover, the cost of purchasing specific equipment is high. At the same time, the weight and volume of fused alumina bricks that are generally machined are large, making calibration and movement during lathe machining quite troublesome. Therefore, it is particularly important to provide a rotary worktable for cutting, grinding and drilling machines for fused alumina bricks that is stable in locking, can be installed and disassembled independently, and can be easily moved. Utility Model Content

[0003] The purpose of this utility model is to provide a rotary worktable for a cutting and grinding machine for fused alumina bricks, which is convenient for locking and moving.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotary table for a cutting and grinding machine for fused alumina bricks, comprising an upper rotary table, the bottom of which is rotatably connected to a base, a locking mechanism fixedly connected to the top of the base along the outer side of the upper rotary table, and a displacement mechanism slidably connected to the lower part of the base through a bracket, the two ends of which are rotatably connected to the original worktable. Through the cooperation of the locking mechanism and the displacement mechanism, the upper rotary table can move freely and be locked and positioned above the original worktable.

[0005] Preferably, the base has a π-shaped structure, and end ears are provided on the front and rear sides of the base. The height of the end ears is slightly higher than the thickness of the support. Two limiting blocks are fixedly connected to the bottom middle of the base. The outer side of the limiting blocks is tightly attached to the inner surface of the support. The end ears, in conjunction with clamps, etc., are used to fix the base to the original worktable, and the limiting blocks are used to limit the displacement mechanism.

[0006] Preferably, the locking mechanism includes a locking ring, which is an open-ring structure. One end of the locking ring is rotatably connected to the locking handle. A locking block is fixed to the inner side of the locking handle, and a locking groove is formed on the outer side of the other end of the locking ring.

[0007] Preferably, the card block and the card slot are connected by an interference fit, and the locking function of the locking mechanism is achieved by pressing the card block into the card slot.

[0008] Preferably, the locking mechanism includes multiple clamping blocks. A gap is maintained between one side of each clamping block and the outer wall of the upper turntable. The clamping block is embedded and slidably connected to one side of the U-shaped block. A top rod is fixed to the other side of the clamping block. The top rod passes through one side of the U-shaped block and is fitted with a spring. One end of the spring is fixed to the inner wall of the U-shaped block, and the other end of the spring is fixed to a limiting ring. The limiting ring is fixed to the other side of the top rod. The tail end of the top rod is in contact with the locking ring, so that the locking mechanism can lock the upper turntable from multiple directions, improving the balance and stability of the locking force. When the locking state is released, the spring can pull the clamping block back into the U-shaped block to prevent affecting the rotation of the upper turntable.

[0009] Preferably, the displacement mechanism includes two supports, which are fixedly connected by a bridge. The supports have n-shaped protrusions on both sides, and a screw is threaded through the top of the n-shaped protrusion. The bottom of the screw is rotatably connected to the top of the wheel frame through a bearing. A first roller is rotatably connected inside the wheel frame. The tail end of the support extends vertically downward to the lower part of the original worktable and is rotatably connected to a second roller on its inner side, so as to facilitate the movement of the support back and forth on the original worktable.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention, through the installation of a locking mechanism, utilizes a combination of a locking handle, a locking block, a locking ring, a clamping block, and a U-shaped block to simultaneously lock the rotating worktable from multiple directions. This results in a more balanced and stable clamping force, eliminating the need for complicated operating procedures and significantly improving work efficiency. Furthermore, the installation of a displacement mechanism allows the rotating worktable to move freely above the original worktable surface, eliminating the previous requirement to repeatedly adjust the position of the fused alumina bricks on the worktable using an overhead crane. This greatly reduces workload and the potential for safety hazards due to improper operation of the hoisting equipment, thus ensuring the safety of workers. Attached Figure Description

Detailed Implementation

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Please see Figure 1-4 A rotary table for a cutting and grinding machine for fused alumina bricks includes an upper rotary table 1. The bottom of the upper rotary table 1 is rotatably connected to a base 2. A locking mechanism 3 is fixedly connected to the top of the base 2 along the outer side of the upper rotary table 1. A displacement mechanism 4 is slidably connected to the lower part of the base 2 through a bracket 401. The two ends of the displacement mechanism 4 are rotatably connected to the original worktable 5. Through the cooperation of the locking mechanism 3 and the displacement mechanism 4, the upper rotary table 1 can move freely and be locked and positioned above the original worktable 5.

[0020] The base 2 has a π-shaped structure. The base 2 has end ears 201 on the front and rear sides. The height of the end ears 201 is slightly higher than the thickness of the support 401. Two limiting blocks 202 are fixed to the bottom middle of the base 2. The outer side of the limiting blocks 202 is tightly attached to the inner surface of the support 401. The end ears 201, together with clamps, etc., are used to fix the base 2 on the original worktable 5. The limiting blocks 202 are used to limit the displacement mechanism 4.

[0021] The locking mechanism 3 includes a locking ring 303, which is an open-loop structure. One end of the locking ring 303 is rotatably connected to the locking handle 301. A locking block 302 is fixedly connected to the inner side of the locking handle 301, and a locking groove 3031 is provided on the outer side of the other end of the locking ring 303.

[0022] The locking block 302 and the slot 3031 are connected by an interference fit, and the locking mechanism 3 achieves its locking function by pressing the locking block 302 into the slot 3031.

[0023] The locking mechanism 3 includes multiple clamping blocks 304. A gap is maintained between one side of each clamping block 304 and the outer wall of the upper turntable 1. Each clamping block 304 is embedded in and slidably connected to one side of a U-shaped block 305. A top rod 306 is fixedly connected to the other side of each clamping block 304. The top rod passes through one side of the U-shaped block 305 and is fitted with a spring 307. One end of the spring 307 is fixedly connected to the inner wall of the U-shaped block 305, and the other end is fixedly connected to a limiting ring 308. The limiting ring 308 is fixedly connected to the other side of the top rod 306. The tail end of the top rod 306 contacts and connects to a locking ring 303, allowing the locking mechanism 3 to lock the upper turntable 1 from multiple directions, improving the balance and stability of the locking force. When the locking is released, the spring 307 can pull the clamping block 304 back into the U-shaped block 305 to prevent affecting the rotation of the upper turntable.

[0024] The displacement mechanism 4 includes two supports 401, which are fixedly connected by a bridge 406. Each support 401 has an n-shaped protrusion 4011 on both sides. The top of the n-shaped protrusion 4011 is threadedly connected to a screw 402. The bottom of the screw 402 is rotatably connected to the top of a wheel frame 403 via a bearing. A first roller 404 is rotatably connected inside the wheel frame 403. The tail end of the support 401 extends vertically downward to the lower part of the original worktable 5 and is rotatably connected to a second roller 405 on its inner side, so as to facilitate the movement of the support 401 back and forth on the original worktable 5.

[0025] Working principle: During the positioning and calibration process, firstly, the n-shaped protrusions 4011 on both sides of the bracket 401 are aligned with the edges of the original worktable 5 and slid in for installation. Tighten the screw 402 so that the second roller 405 contacts the bottom surface of the original worktable 5. At this time, the bracket 401 can move freely back and forth on the original worktable 5. Then, the limiting block 202 under the base 2 is aligned with the inside of the bracket 401 and installed. At this time, the base 2 can slide left and right above the bracket 401 to meet the working position requirements. During the locking process, firstly, the screw 402 is tightened so that the lower middle surface of the bracket 401 contacts the upper surface of the original worktable 5. At this time, the end ear 201 of the base 2 contacts the upper surface of the original worktable 5. The base 2 is fixed to the original worktable 5 by the clamp. Finally, the locking handle 301 is pressed into the slot 3031. At this time, the locking ring 303 tightens inward, driving the push rod 306 to move inward. At the same time, the push rod 306 drives the clamping block 304 to move inward and contact the outer wall of the upper turntable 1 to achieve the locking purpose.
