Description

Technical Field

[0001] The present application belongs to the technical field of drilling and cutting equipment, and specifically relates to a table structure of a drilling and cutting machine. Background Art

[0002] In material production, drilling and cutting are often used. Usually, drilling and cutting machines are used to perform drilling and cutting operations on materials. When drilling and cutting, the head of the drilling and cutting machine needs to be accurately aligned with the material, and the material is drilled and cut according to the preset drilling and cutting position. When drilling and cutting materials, slight vibration or displacement of the material will cause the head to deviate, thereby affecting the drilling and cutting accuracy. Therefore, higher requirements are placed on the placement stability of the material. Traditional drilling and cutting machines use clamps to clamp and fix the material, thereby improving the drilling and cutting stability of the material. However, due to the influence of the machine body processing accuracy, the flatness of the material bearing table is usually not high, which can easily cause the material to be placed tilted, thereby affecting the drilling and cutting accuracy of the material.

[0006] The table structure of the drilling and cutting machine described in this application also includes the following additional technical features:

[0007] Along the span direction of the crossbeam, the plurality of material supporting members installed on the front processing material platform and the plurality of material supporting members installed on the rear processing material platform are arranged alternately.

[0008] The front processing material platform and the rear processing material platform are respectively provided with support plates located below the material support member, and the support plates are installed with top screws to adjust the material support member to move up and down through the top screws.

[0009] The material support is provided with a waist-shaped hole whose long axis extends in the vertical direction. The front processing material table and the rear processing material table are respectively provided with threaded holes corresponding to the waist-shaped hole. The material support is loosened or locked by threaded fasteners passing through the waist-shaped holes and cooperating with the threaded holes.

[0010] The front processing material platform includes multiple front loading platforms, and the multiple front loading platforms are arranged at intervals along the extension direction of the crossbeam. The rear processing material platform includes multiple rear loading platforms, and the multiple rear loading platforms are arranged at intervals along the extension direction of the crossbeam. The front loading platforms and the rear loading platforms are arranged opposite to each other in the front-to-back direction, and each of the front loading platforms and each of the rear loading platforms are installed with material supports.

[0011] The front loading platform and the rear loading platform extend in the front-to-back direction, the material support installed on the front loading platform is located at one end of the front loading platform close to the rear loading platform, and the material support installed on the rear loading platform is located at one end of the rear loading platform close to the front loading platform.

[0012] The front processing material platform, the rear processing material platform and the material support are all equipped with material carrying rollers.

[0013] The front processing platform is equipped with a plurality of material-carrying rollers, which are distributed on two opposite sides of the front processing platform; the rear processing platform is equipped with a plurality of material-carrying rollers, which are distributed on two opposite sides of the rear processing platform.

[0014] The front processing material platform and the rear processing material platform are respectively detachably mounted on the frame.

[0015] The loading platform and the unloading platform are both equipped with material guiding rollers.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0017] 1. The table structure of the drilling and cutting machine of the present application includes a loading table located at the front side of the combined machine head, an unloading table at the rear side of the combined machine head, and a processing table located between the loading table and the unloading table. When processing materials, the materials are transported to the processing table through the loading table, and then transported out through the unloading table after the material processing is completed, thereby realizing the streamlined operation of drilling and cutting materials and greatly improving the continuity of drilling and cutting of materials; and the processing table of the present application includes a front processing table and a rear processing table. The drilling and cutting machine can choose to respectively set the combined machine head at the corresponding positions of the front processing table and the rear processing table, so as to drill and cut the materials from the front processing table and the rear processing table at the same time, thereby greatly improving the drilling and cutting efficiency of the materials; in addition, by respectively installing material support members that can move up and down in the vertical direction at the front processing table and the rear processing table, when the materials are transported to the processing table, the materials can be easily cut. When the material table is reached, the material support is controlled to lift the material, and the flatness of the material placement is adjusted by controlling the vertical height of the material support located on the front processing table and the rear processing table, so that the material is carried in a relatively flat position. On the one hand, the processing accuracy during drilling and cutting is improved, and the probability of inaccurate drilling and cutting positioning caused by the tilted material placement is reduced; on the other hand, the material is lifted to a certain height under the support of the material support, avoiding obstruction to the material by the loading table, unloading table or other components on the frame, thereby providing a guarantee for the stability of the material drilling and cutting work; and when the material drilling and cutting work is completed, the material support plate can be controlled to descend until the bottom surface of the material is flush with the top surface of the unloading table, and the drilled and cut material can be operated to be sent out of the drilling and cutting machine through the unloading table, thus realizing the continuous processing of the material by the drilling and cutting machine.

[0018] 2. As a preferred embodiment of the present application, since the material will be subjected to vibration impact during drilling and cutting, the material will tend to be relatively displaced with the material support under the vibration impact, affecting the support accuracy of the material and thus affecting the drilling and cutting accuracy. The multiple material supports installed on the front processing platform and the multiple material supports installed on the rear processing platform are arranged alternately, so that the projections of the material support located on the front processing platform and the material support located on the rear processing platform on the vertical plane are misaligned. When the material tends to move on the material support, for example, the material tends to move from the direction of the front processing platform to the direction of the rear processing platform, due to the misalignment of the material supports at both ends, the sliding stress transmitted from the front side to the rear side of the material cannot be effectively transmitted, thereby hindering the sliding of the material and improving the support stability of the material support for the material.

[0019] 3. As a preferred embodiment of the present application, by providing a support plate and a top screw, and lifting or lowering the support plate by the top screw to control the up and down movement of the material support, the lifting area of ​​the material support surface is increased, and the movement stability of the material support is improved, so that the material support located on the front processing material table and the material product located on the rear processing material table can be more accurately adjusted in vertical height, which helps to improve the flatness of material placement; in addition, when the material is subjected to vibration impact during the drilling and cutting process, this part of the vibration impact will diffuse and transmit downward through the material support, and the support plate supports the material support, which can play a role in uniformly conducting the vibration potential energy in the material support, which helps to quickly transmit and dissipate the vibration potential energy and impact potential energy of the material, further improve the placement stability of the material, and help to improve the drilling and cutting accuracy.

[0020] 4. As a preferred embodiment of the present application, a waist-shaped hole with a long axis extending in the vertical direction is provided. On the one hand, a detachable connection between the material support and the front processing material table and the rear processing material table is realized through threaded fasteners. When the height of the material support needs to be adjusted, the threaded fasteners can be loosened to adjust the height of the material support. On the other hand, the long axis of the waist-shaped hole extends in the vertical direction, which increases the overlapping length of the threaded hole and the waist-shaped hole in the vertical direction, thereby increasing the adjustable range of the material support in the vertical direction.

[0021] 5. As a preferred embodiment of the present application, by respectively arranging a plurality of front loading platforms on the front processing platform, and a plurality of rear loading platforms on the rear processing platform, and respectively arranging material supports on each front loading platform and the rear loading platform, on the one hand, the contact area between the material and the material support can be increased, thereby improving the support stability of the material; on the other hand, when the volume of the material is large, the plurality of material supports can jointly assume the function of carrying the material, thereby increasing the total contact area between the material support and the material, so that the material can be stably drilled and cut under the joint support of the plurality of material supports.

[0022] 6. As a preferred embodiment of the present application, rollers are arranged on the front processing platform and the rear processing platform to facilitate the transportation of materials from the loading platform to the front processing platform, the transportation of materials from the rear processing platform to the lower platform, and the adjustment of the position of materials at the processing platform. The rollers are driven by rolling friction between the materials, which, on the one hand, reduces the wear on the bottom surface of the materials and helps to maintain the integrity of the materials; on the other hand, it reduces the resistance encountered during the transportation of materials, thereby improving the loading efficiency, unloading efficiency, and position adjustment efficiency of the materials at the processing platform.

[0048] Embodiment 1: The projections of the multiple material support members 8 installed on the front processing platform 71 and the multiple material support members 8 installed on the rear processing platform 72 along the length direction of the beam 1 overlap.

[0049] Implementation method 2: Figure 2 , Figure 3As shown, along the span direction of the beam 1, the plurality of material supports 8 installed on the front processing platform 71 and the plurality of material supports 8 installed on the rear processing platform 72 are arranged alternately. Since the material is subjected to vibration impact during drilling and cutting, the material tends to be relatively displaced with the material supports 8 under vibration impact, affecting the support accuracy of the material, thereby affecting the drilling and cutting accuracy. The plurality of material supports 8 installed on the front processing platform 71 and the plurality of material supports 8 installed on the rear processing platform 72 are arranged alternately, so that the projections of the material supports 8 located on the front processing platform 71 and the material supports 8 located on the rear processing platform 72 on the vertical plane are misaligned. When the material tends to move on the material supports 8, for example, when the material tends to move from the front processing platform 71 to the rear processing platform 72, due to the misalignment of the material supports 8 at both ends, the sliding stress transmitted from the front side to the rear side of the material cannot be effectively transmitted, thereby hindering the sliding of the material and improving the support stability of the material supports 8 on the material.
