Description

Technical Field

[0001] This utility model belongs to the technical field of boring machine equipment, specifically the rotary table of a boring machine. Background Technology

[0002] A boring machine is a machine tool that mainly uses a boring bar to bore pre-drilled holes in a workpiece. Usually, the rotation of the boring bar is the main motion, and the movement of the boring bar or the workpiece is the feed motion, so as to realize the boring process of pre-drilled holes on the workpiece. It is widely used in the field of machining.

[0003] The boring machine table is a key component in machine tool processing used to fix the workpiece and bear the machining chips. It is connected to the slot on the worktable by a fixed fixture, and the part to be machined is fixed on the worktable using the fixed fixture. However, the boring machine table in the prior art is a fixed structure. When different surfaces of the part need to be machined, the part needs to be removed from the fixed fixture, and then the relative surfaces between the part and the tool need to be adjusted. After that, the fixed fixture needs to be used again to clamp the part. This repeated operation makes the process cumbersome and affects the machining efficiency.

[0004] Therefore, this utility model provides a boring machine rotary table. Utility Model Content

[0005] To overcome the shortcomings of the prior art and solve the problem that the boring machine table in the prior art is a fixed structure, when different surfaces of the part need to be machined, the part needs to be removed from the fixed fixture, and then the relative surfaces between the part and the tool need to be adjusted. After that, the fixed fixture needs to be used again to clamp the part. This repeated operation makes the process cumbersome and affects the machining efficiency. Therefore, the proposed boring machine rotary table is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The boring machine rotary table of this utility model includes a base plate, a through hole in the middle of the base plate, an anti-wear component in the through hole, a rotating shaft mounted on the anti-wear component, a table surface fixed to the top of the rotating shaft, multiple positioning holes in both the base plate and the table surface, fixing pins placed in the positioning holes, a support component and a protective component on the top of the base plate, a gripping component on the side wall of the table surface, and a reinforcing component at the bottom of the fixing pin. Through the above structure, the base plate, table surface, positioning holes, and fixing pins cooperate to facilitate the rotation of the fixed fixture and parts mounted on the table surface, thereby changing the surface of the parts relative to the cutting tool, reducing the need to remove the parts from the fixed fixture for changing the surface and then re-clamping, which leads to a cumbersome process and low processing efficiency.

[0007] Preferably, the support assembly includes multiple support seats, which are arranged in a circumferential array on the top of the base plate. A swivel ball is installed on the top of each support seat, and the swivel ball contacts the bottom of the tabletop. Through the above structure, the support seats and the swivel ball connect the base plate and the tabletop, and the stability of the tabletop position can be improved by providing support at multiple points.

[0008] Preferably, the wear-resistant component includes a bearing, the outer ring of which is mounted on the inner wall of the through hole, and the rotating shaft is mounted on the inner ring of the bearing. With the above structure, the bearing is mounted between the base plate and the rotating shaft, which can convert the sliding friction between the rotating shaft and the base plate into rolling friction, thereby reducing the wear between the base plate and the rotating shaft.

[0009] Preferably, the protective component includes a retaining ring, which is fixed to the top of the base plate. The top of the retaining ring is infinitely close to the bottom of the countertop. With the above structure, the retaining ring is installed between the base plate and the countertop, which can effectively prevent debris from entering the gap between the base plate and the countertop, thereby reducing the adhesion of debris to the internal structure of the base plate and the countertop, which could lead to contamination and blockage.

[0010] Preferably, the gripping assembly includes multiple extension rods, which are fixed to the side wall of the tabletop. The extension rods are correspondingly arranged with the positioning holes. With the above structure, the extension rods can provide a position for applying force from the side when rotating the tabletop, and the operator's hand can firmly grip the extension rods to reduce slippage, thereby improving the convenience and stability when rotating the tabletop.

[0011] Preferably, the reinforcing component includes a magnet, which is installed at the bottom of the fixing pin. With the above structure, the magnet is attracted to the bottom of the positioning hole on the base plate, which can improve the stability of the fixing pin in the positioning hole, thereby reducing the possibility of the fixing pin coming out of the positioning hole during processing.

[0012] Preferably, the tabletop surface is provided with a nitride coating. Through the above structure, the nitride coating on the tabletop surface can significantly improve the wear resistance of the tabletop surface, thereby reducing the wear of the tabletop surface.

[0013] The beneficial effects of this utility model are as follows: 1. The boring machine rotary table of this utility model, through the cooperation of the base plate, table surface, positioning hole and fixing pin, can facilitate the rotation of the fixed fixture and parts installed on the table surface, thereby changing the surface of the parts relative to the cutting tool, so as to reduce the need to remove the parts from the fixed fixture for changing the surface and then clamping them, which leads to a more cumbersome process and low processing efficiency.

[0014] 2. The boring machine rotary table of this utility model is connected between the base plate and the table surface by a support base and a universal ball joint. The stability of the table surface position can be improved by providing support at multiple points. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] like Figures 1 to 5As shown in the embodiment of this utility model, the rotary table of the boring machine includes a base plate 1. A through hole 11 is provided in the center of the base plate 1. An anti-wear component is provided within the through hole 11. A rotating shaft 12 is mounted on the anti-wear component. A table surface 13 is fixedly connected to the top of the rotating shaft 12. Multiple positioning holes 14 are provided on both the base plate 1 and the table surface 13. Fixing pins 15 are placed within the positioning holes 14. A support component and a protective component are provided on the top of the base plate 1. A gripping component is provided on the side wall of the table surface 13. A reinforcing component is provided at the bottom of the fixing pins 15. During operation, after the base plate 1 is installed on the boring machine, a workpiece fixing fixture is installed on the table surface 13, and then the workpiece is clamped using the fixing fixture. When machining is required... When changing the surface of a part to be machined, first remove the fixing pin 15 from the positioning hole 14. Then, rotate the table 13 to rotate the fixture and the part, thereby changing the relative surface of the part and the boring tool. Then, align the base plate 1 with the positioning hole 14 on the table 13, and insert the fixing pin 15 into the positioning hole 14 to fix the position of the table 13. Through the above structure, the cooperation of the base plate 1, table 13, positioning hole 14, and fixing pin 15 makes it easy to rotate the fixture and the part mounted on the table 13, thereby changing the surface of the part relative to the tool. This reduces the need to remove the fixture from the part to change the surface and then clamp it again, which would otherwise result in a cumbersome process and low machining efficiency.

[0021] like Figure 2 and Figure 4 As shown, the support assembly includes multiple support seats 2, which are arranged in a circular array on the top of the base plate 1. A universal ball 21 is installed on the top of each support seat 2, and the universal ball 21 contacts the bottom of the tabletop 13. During operation, when the tabletop 13 rotates, it will drive the universal ball 21 to rotate. When the tabletop 13 is stationary, the support seats 2 and the universal ball 21 will support it from the bottom of the tabletop 13. Through the above structure, the support seats 2 and the universal ball 21 connect the base plate 1 and the tabletop 13. The stability of the tabletop 13 position can be improved by providing support at multiple points.

[0022] like Figure 3 and Figure 4 As shown, the anti-wear component includes a bearing 3. The outer ring of the bearing 3 is installed on the inner wall of the through hole 11, and the rotating shaft 12 is installed on the inner ring of the bearing 3. During operation, when the table 13 rotates, it will drive the rotating shaft 12 to rotate together. At this time, the rotating shaft 12 will drive the inner ring of the bearing 3 to rotate. Through the above structure, the bearing 3 is installed between the base plate 1 and the rotating shaft 12, which can convert the sliding friction between the rotating shaft 12 and the base plate 1 into rolling friction, thereby reducing the wear between the base plate 1 and the rotating shaft 12.

[0023] like Figure 3As shown, the protective component includes a retaining ring 4, which is fixed to the top of the base plate 1. The top of the retaining ring 4 is very close to the bottom of the tabletop 13. During operation, when the tool cuts the parts, a lot of debris is generated. When the debris enters the gap between the base plate 1 and the tabletop 13, the retaining ring 4 installed between the base plate 1 and the tabletop 13 can block the debris. Through the above structure, the retaining ring 4 installed between the base plate 1 and the tabletop 13 can effectively prevent debris from entering the gap between the base plate 1 and the tabletop 13, thereby reducing the adhesion of debris to the internal structure of the base plate 1 and the tabletop 13, which could lead to contamination and jamming.

[0024] like Figure 1 As shown, the gripping assembly includes multiple extension rods 5, which are fixed to the side wall of the tabletop 13. The extension rods 5 are correspondingly arranged with the positioning holes 14. During operation, when rotating the tabletop 13, the operator can grip the extension rods 5 to apply force, thereby driving the tabletop 13 to rotate. Through the above structure, the extension rods 5 can provide a position for applying force from the side when rotating the tabletop 13. The operator's hands can firmly grip the extension rods 5 to reduce slippage, thereby improving the convenience and stability when rotating the tabletop 13.

[0025] like Figure 5 As shown, the reinforcement component includes a magnet 6, which is installed at the bottom of the fixing pin 15. During operation, after the fixing pin 15 is inserted into the positioning hole 14, the magnet 6 at the bottom of the fixing pin 15 will be attracted to the bottom of the positioning hole 14 on the base plate 1. Through the above structure, the magnet 6 is attracted to the bottom of the positioning hole 14 on the base plate 1, which can improve the stability of the fixing pin 15 in the positioning hole 14, thereby reducing the possibility of the fixing pin 15 coming out of the positioning hole 14 during processing.

[0026] like Figure 1 As shown, the surface of the tabletop 13 is provided with a nitride coating. Through the above structure, the nitride coating on the surface of the tabletop 13 can significantly improve the wear resistance of the surface of the tabletop 13, thereby reducing the wear on the surface of the tabletop 13.

[0027] Working principle: After mounting the base plate 1 on the boring machine, the workpiece fixing fixture is mounted on the table 13. The workpiece is then clamped using the fixing fixture. When it is necessary to change the surface to be machined on the workpiece, first remove the fixing pin 15 from the positioning hole 14. Then, rotate the table 13 to rotate the fixing fixture and the workpiece, thereby changing the relative surface between the workpiece and the boring machine tool. Then, align the base plate 1 with the positioning hole 14 on the table 13, and insert the fixing pin 15 into the positioning hole 14 to fix the position of the table 13. When the table 13 rotates, it will drive the universal ball 21 to rotate. When the table 13 is stopped, the support base 2 and the universal ball 21 rotate. The ball 21 is supported from the bottom of the table 13. When the table 13 rotates, it will drive the shaft 12 to rotate as well. At this time, the shaft 12 will drive the inner ring of the bearing 3 to rotate. When the tool cuts the part, it will generate a lot of debris. When the debris enters the gap between the base plate 1 and the table 13, the retaining ring 4 is installed between the base plate 1 and the table 13 to block the debris. When rotating the table 13, the operator can hold the extension rod 5 to apply force, thereby driving the table 13 to rotate. After the fixing pin 15 is inserted into the positioning hole 14, the magnet 6 at the bottom of the fixing pin 15 will be attracted to the bottom of the positioning hole 14 on the base plate 1.
