Description

Technical Field

[0001] This utility model relates to the field of boring machine columns, and more particularly to a support structure for a boring machine column. Background Technology

[0002] In the machining process, the boring machine is a key piece of equipment for realizing complex processes such as high-precision hole machining and plane milling. Its column structure is the foundation for supporting components such as the bearing seat and the worktable. It is directly related to the stability of the machining process of the bearing seat, the worktable and other components and the accuracy of the final product. The column needs to withstand multiple loads such as cutting force and the weight of the components during operation, and at the same time, it needs to cooperate with the machining axis to complete the position adjustment.

[0003] Therefore, the rationality and reliability of its support structure are important prerequisites for ensuring the efficient operation of the boring machine. However, the support structure of the traditional boring machine column still has shortcomings in practical applications.

[0004] First, the boring machine column needs to provide support for the spindle seat. This support is usually provided by the slide rail and screw on the boring machine column. The support points of the spindle seat and the screw are fixed. During long-term use, the spindle seat is prone to slight deformation due to the heavier end away from the column under the action of leverage, which in turn affects the machining accuracy.

[0005] To address this issue, a support structure for the boring machine column is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a support structure for a boring machine column, which aims to improve the problem in the existing technology where the spindle seat is supported only by the slide rail and screw, the support point is fixed, and the far end is heavy and easily deformed by the lever action, thus affecting the machining accuracy.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a support structure for a boring machine column, including a support frame, a drive motor is provided at the top of the support frame, a drive screw is fixedly connected to the output shaft of the drive motor, a positioning sleeve is threadedly connected to the outer wall of the drive screw, a shaft seat is fixedly connected to the upper section of the outer wall of the positioning sleeve, a slide rail is fixedly connected to the front surface of the support frame, a reinforcing component is provided inside the support frame, and a support component is provided at the front end of the support frame; The support assembly includes a support base, which is fixedly connected to the outer wall of the positioning sleeve. A first slot is provided on the front surface of the support base, and a first insert is inserted into the inner wall of the first slot. A support plate is fixedly connected to the upper surface of the first insert. A second slot is provided on the front surface of the bearing seat, and a second insert is fixedly connected to the upper surface of the support plate.

[0008] As a further description of the above technical solution: The support assembly also includes a slide rod that passes through and is slidably connected to the lower surface of the support base. The inner wall of the bottom end of the support base is elastically connected to a slide plate via an elastic element. A limit block is fixedly connected to the upper surface of the slide plate, and a handle is fixedly connected to the lower surface of the slide rod.

[0009] As a further description of the above technical solution: The reinforcement component includes multiple sets of reinforcement blocks, which are fixedly connected in an array to the inner surface of the support frame. The outer wall of the support frame is fixedly connected with a reinforcement plate.

[0010] As a further description of the above technical solution: The drive screw passes through and is rotatably connected to the inner surface of the support frame, and the bearing seat is slidably connected to the outer wall of the slide rail.

[0011] As a further description of the above technical solution: The first and second inserts are configured in an "I" shape, and the first and second slots are configured in a "T" shape.

[0012] As a further description of the above technical solution: The sliding plate is slidably connected to the inner wall of the support base, and the limiting block is engaged with the left side of the first insert block.

[0013] As a further description of the above technical solution: The left end of the limiting block is set as an inclined surface that is lower on the left and higher on the right.

[0014] As a further description of the above technical solution: The end of the reinforcing block furthest from the support frame is fixedly connected to the reinforcing plate, and the reinforcing block is configured as an "X".

[0015] This utility model has the following beneficial effects: 1. In this utility model, by cooperating with the support components, the first insert, the second insert, the first slot, and the second slot are connected to form a triangular stable structure with the support plate. This can disperse the load at the far end of the bearing seat, enhance the stability of the support structure, alleviate the deformation problem caused by the lever action, and ensure the processing accuracy of the device.

[0016] 2. In this utility model, through the cooperation of the reinforcing components, multiple sets of "X-shaped" reinforcing blocks are connected to the reinforcing plate. Since the thickness of the reinforcing blocks is greater than that of the traditional boring machine column support, and the triangular support formed by the array distribution can enhance the overall strength and deformation resistance of the column, the formation of the cavity reduces the structural weight, achieving a balance between high strength and lightweight, and ensuring the stability of the column in use.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a boring machine column support structure, including a support frame 1 for supporting the overall device. The support frame 1 is the inner frame of the column. A drive motor 2 is provided at the top of the support frame 1. The output shaft of the drive motor 2 is fixedly connected to a drive screw 3. Both the drive motor 2 and the drive screw 3 are used to drive a shaft seat 5. Both are existing technologies and can be implemented by those skilled in the art. Since they are existing technologies, they will not be described in detail in this case. A positioning sleeve 4 is threadedly connected to the outer wall of the drive screw 3. When the drive motor 2 drives the drive screw 3 to rotate, it will drive the positioning sleeve 4 to move longitudinally. A shaft seat 5 is fixedly connected to the upper section of the outer wall of the positioning sleeve 4. The shaft seat 5 is part of the column. A slide rail 6 is fixedly connected to the front surface of the support frame 1 to provide guidance for the shaft seat 5. A reinforcing component 7 to enhance the strength of the column is provided inside the support frame 1. A support component 8 to enhance the stability of the column support is provided at the front end of the support frame 1. The support component 8 can strengthen the support of the shaft seat 5 to ensure the stability of the shaft seat 5 when it moves longitudinally.

[0021] Reference Figure 1, Figure 3 , Figure 4 The support assembly 8 includes a support base 81, which is fixedly connected to the outer wall of the positioning sleeve 4. The support base 81 is located in the lower half of the outer wall of the positioning sleeve 4. A first slot 82 is provided on the front surface of the support base 81. A first insert 83 is inserted into the inner wall of the first slot 82. The first slot 82 penetrates the front and upper surfaces of the support base 81. A support plate 84 is fixedly connected to the upper surface of the first insert 83. The support plate 84 is inclined and can form a triangle with the bearing 5, the support base 81, and the positioning sleeve 4, which can improve stability. A second slot 85 is provided on the front surface of the bearing 5. The second slot 85 penetrates the lower and front surfaces of the bearing 5. A second insert 86 is fixedly connected to the upper surface of the support plate 84.

[0022] Reference Figure 1 , Figure 3 , Figure 4 The support assembly 8 also includes a slide rod 810, which is slidably connected to the lower surface of the support base 81. The slide rod 810 moves longitudinally. The inner wall of the bottom end of the support base 81 is elastically connected to a slide plate 89 through an elastic element 87. A limit block 88 is fixedly connected to the upper surface of the slide plate 89. The slide plate 89 and the limit block 88 move synchronously. A handle 811 is fixedly connected to the lower surface of the slide rod 810 for easy gripping. Pulling the handle 811 downwards can drive the slide rod 810 to move downwards.

[0023] Reference Figure 1 , Figure 3 , Figure 4 The drive screw 3 passes through and is rotatably connected to the inner surface of the support frame 1. The bearing seat 5 is slidably connected to the outer wall of the slide rail 6, which can ensure the stability of longitudinal movement. The first insertion block 83 and the second insertion block 86 are set in an "I" shape, and the first slot 82 and the second slot 85 are opened in a "T" shape. The slide plate 89 is slidably connected to the inner wall of the support seat 81. The limiting block 88 is engaged with the left side of the first insertion block 83, which can limit the first insertion block 83. The left end of the limiting block 88 is set as a slope that is lower on the left and higher on the right. When the first insertion block 83 is inserted, the slope of the limiting block 88 will be squeezed, and the limiting block 88 will move downward to release the obstruction. Therefore, the limiting block 88 can only provide a unidirectional limiting function for the first insertion block 83.

[0024] Reference Figure 1 - Figure 2The reinforcement component 7 includes multiple sets of reinforcement blocks 72, which are fixedly connected in an array to the inner surface of the support frame 1. A reinforcement plate 71 is fixedly connected to the outer wall of the support frame 1. The thickness of the reinforcement blocks 72 is greater than that of the conventional boring machine column support, which can ensure the stability of the support. The end of the reinforcement block 72 away from the support frame 1 is fixedly connected to the reinforcement plate 71. The reinforcement blocks 72 are set in an "X" shape, and cavities can be formed between the reinforcement blocks 72, which can reduce the overall weight and achieve lightweighting. In addition, multiple reinforcement blocks 72 are in contact with each other and can form multiple "small triangles" to ensure stability.

[0025] Working principle: After the drive motor 2 at the top of the support frame 1 is started, its output shaft drives the drive screw 3 to rotate, which in turn drives the positioning sleeve 4 to move longitudinally. The shaft seat 5 on the outer wall of the positioning sleeve 4 slides synchronously along the slide rail 6 on the front surface of the support frame 1, so as to realize the height adjustment of the shaft seat 5 and meet the position requirements of different processing scenarios.

[0026] The support plate 84 in the support assembly 8 is connected to the first slot 82 and the second slot 85 through the first insert 83 and the second insert 86 at both ends, respectively, to form a triangular stable structure, which enhances the stability of the bearing seat 5 and avoids shaking during the adjustment process.

[0027] When the first insert 83 is inserted into the first slot 82, it will press the inclined surface of the limiting block 88, causing the slide plate 89 to compress the elastic element 87 and move downward. After the first insert 83 is inserted, the elastic element 87 returns to its original position, causing the limiting block 88 to be locked into the left side of the first insert 83. If disassembly is required, the slide bar 810 is pulled down by the handle 811, causing the slide plate 89 and the limiting block 88 to move downward, and the support plate 84 can be pulled out after the lock is released.

[0028] In the reinforcement components 7 inside the support frame 1, multiple sets of "X-shaped" reinforcement blocks 72 are arranged in an array. One end is fixed to the inner surface of the support frame 1, and the other end is connected to the reinforcement plate 71 on the outer wall. The "X-shaped" structure forms multiple triangular support parts, which can reduce the overall weight while improving the strength of the support frame 1 and ensuring the stability of the column.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
