Description

Technical Field

[0001] The invention relates to the technical field of compound machine tools, in particular to a multifunctional compound machine tool for laboratory use. Background Art

[0002] In a laboratory environment, machining tasks have their own particularity and diversity requirements. Existing conventional machine tools are difficult to fully meet these requirements and have many obvious defects.

[0003] Traditional machine tools have relatively single functions. For example, ordinary milling machines can only perform milling processing, and drilling machines are limited to drilling operations. In laboratories, research projects often involve the manufacture of complex workpieces or the processing of samples. These workpieces often require a combination of multiple different processes. When using existing machine tools, the workpieces have to be transferred back and forth between machine tools with different functions. In this process, each time the workpiece is clamped on a new machine tool, it is inevitable that clamping errors will occur, because the clamping systems of different machine tools are different. Even small deviations will have a serious negative impact on the final processing accuracy when accumulated, resulting in a significant reduction in the accuracy of the experimental results. At the same time, frequent clamping operations are extremely time-consuming, greatly reducing the overall processing efficiency and extending the experimental cycle, which is extremely unfavorable for time-sensitive scientific research projects.

[0004] In addition, in order to cope with various possible processing needs, if the laboratory uses existing machine tools, it will need to purchase a large number of different types of machine tool equipment, which not only greatly increases the cost of equipment purchase, but also many machine tools occupy a huge area, and the limited space of the laboratory is occupied. In a laboratory environment with tight space resources, this will cause a chaotic space layout and may even affect the placement and operation of other experimental equipment, which is not conducive to the overall planning and efficient operation of the laboratory.

[0005] To this end, we propose a multifunctional composite machine tool based on laboratory use. Summary of the invention

[0006] The purpose of the present invention is to provide a multifunctional composite machine tool for laboratory use.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multifunctional compound machine tool for laboratory use, comprising a box body, a through hole 1 is opened in the middle of the top of the box body, a pillar is arranged at the center of the through hole 1, the bottom of the pillar is fixedly connected to the bottom plate of the box body, each side of the pillar is provided with a linear guide rail, and the linear guide rail is provided with corresponding processing equipment, and a base is also provided on the top of the box body, an inner gear type slewing bearing is provided on the inner periphery of the base, an inner ring is provided on the inner side of the inner gear type slewing bearing, an outer ring is provided on the outer side of the inner gear type slewing bearing, and the outer ring is fixed to the inner periphery of the base, a motor is provided at the bottom of the base, a driving gear is provided at the output end of the top of the motor, and the driving gear is meshed with the gear ring provided on the inner ring for transmission, a turntable is fixedly connected to the top of the inner ring, a plurality of groups of clamping assemblies are provided on the top of the turntable, and the plurality of groups of clamping assemblies are fixed to the top of the turntable in a ring array;

[0008] The clamping assembly includes a clamping seat, a bidirectional screw and a clamping block. The two ends of the bidirectional screw are rotatably connected to bearings provided on both sides of the clamping seat. The bottom ends of the two clamping blocks are provided with threaded holes, which are respectively matched with the threads at the two ends of the bidirectional screw.

[0009] As a further solution of the present invention: the pillar is in a regular quadrangular prism structure, and the four linear guide rails are respectively fixed to four side surfaces of the pillar.

[0010] As a further solution of the present invention: processing equipment with different functions are respectively installed on the sliders of the four linear guide rails.

[0011] As a further solution of the present invention: a plurality of cushion blocks are provided on the top of the box body, and the cushion blocks are fixedly connected to the base.

[0012] As a further solution of the present invention: a second through hole is opened in the middle of the base, and the inner wall of the base is tightly fitted with the outer wall of the internal gear slewing bearing.

[0013] As a further solution of the present invention: the top of the inner ring of the internal gear slewing bearing is fastened to the bottom of the turntable by bolts, and a third opening is opened in the middle of the turntable.

[0014] As a further solution of the present invention: the clamping components are provided with four groups, and the bottoms of the four groups of clamping components are provided with corresponding cross modules, and the cross modules are used to adjust the positions of the clamping components in the X-axis direction and the Y-axis direction.

[0015] As a further solution of the present invention: the upper module slider 2 in the cross module is fixedly connected to the bottom of the clamping seat.

[0016] As a further solution of the present invention: a limit block is provided on the top of the clamp seat, and two limit grooves corresponding to the threads at both ends of the bidirectional screw are opened on the top of the limit block, and the limit grooves are located directly above the bidirectional screw, and the inner wall of the limit groove is in a close-fitting sliding fit with the outer wall of the clamping block.

[0017] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The present invention fixes linear guide rails on the four sides of the pillar, and processing equipment with different functions is installed on each linear guide slider. This layout enables the machine tool to process the workpiece in multiple directions. For example, the processing equipment on one side can perform milling processing, and the other side can perform drilling processing, etc. At the same time, the clamping assembly on the turntable can clamp the workpiece for rotation in the circumferential direction. With the processing equipment on different sides, all-round and multi-process processing of the workpiece can be achieved. In addition, due to the arrangement of the linear guide rail and the turntable, the position of the processing equipment and the angle of the workpiece can be flexibly adjusted, which means that different processing methods can be combined according to different processing requirements. For example, the turntable is first used to rotate the workpiece to a suitable angle, and one processing equipment is used for rough processing, and then the workpiece is rotated, and another processing equipment is used for fine processing, thereby achieving seamless connection of multiple processing techniques, meeting the requirements of complex processing tasks, and greatly increasing the functional diversity of the machine tool;

[0019] 2. The cross module and the clamping assembly in the present invention cooperate with each other, so that various parts of the workpiece can be quickly and accurately sent to the processing position of the processing equipment without re-clamping the workpiece, thereby improving the processing efficiency and processing accuracy. The cross module moves the workpiece to a new position in the plane by accurately controlling the displacement of the clamping seat in the X-axis and Y-axis directions. At the same time, since the turntable can drive the clamping assembly and the workpiece to rotate in the circumferential direction, combined with the plane adjustment of the cross module, it can meet the processing requirements of different parts of the workpiece;

[0020] 3. The present invention integrates a variety of processing equipment with different functions into one machine tool structure, which effectively saves space. The entire machine tool is based on a box, the pillar is located in the middle of the top of the box, the linear guide rail is set on the side of the pillar, the turntable and the clamping assembly are located in the top area of ​​the box above the pillar. This layout makes the various components closely combined without excessive space waste. By integrating a variety of processing equipment on the linear guide rail of the pillar and using the clamping assembly on the turntable to achieve multi-angle processing of the workpiece, it is avoided to set up large equipment and corresponding workpiece clamping areas for each processing function. For example, there is no need to set up independent machine tools and clamping stations for different processing functions such as milling and drilling, which reduces the space occupation caused by the dispersion of equipment, so that places with limited space such as laboratories can use space more effectively.

[0021] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

DETAILED DESCRIPTION

[0029] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0030] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Please refer to the attached Figure 1 -Attached Figure 6The present invention is a multifunctional compound machine tool for laboratory use, comprising a box body 1, a through hole 11 is opened in the middle of the top of the box body 1, a pillar 2 is arranged at the center of the through hole 11, the bottom of the pillar 2 is fixedly connected to the bottom plate of the box body 1, each side of the pillar 2 is provided with a linear guide 3, and the linear guide 3 is provided with corresponding processing equipment. This multi-faceted arrangement of the linear guide 3 can realize a variety of processing operations in different directions and types on a single machine tool, greatly increasing the functionality of the machine tool, eliminating the need to transfer the workpiece on multiple machine tools with different functions, saving processing time and labor costs, a base 4 is also arranged on the top of the box body 1, an inner gear slewing bearing 5 is arranged on the inner periphery of the base 4, an inner ring 51 is arranged on the inner side of the inner gear slewing bearing 5, and the inner gear An outer ring 52 is provided on the outer side of the internal gear slewing bearing 5, and the outer ring 52 is fixed to the inner periphery of the base 4. A motor 6 is provided at the bottom of the base 4. A driving gear 61 is provided at the output end of the top of the motor 6. The driving gear 61 is meshed with a gear ring 511 provided on the inner ring 51 for transmission. A turntable 7 is fixedly connected to the top of the inner ring 51. The motor 6 is meshed with the gear ring 511 of the inner ring 51 of the internal gear slewing bearing 5 through the driving gear 61, so that the turntable 7 can rotate smoothly. A plurality of clamping assemblies 8 are provided on the top of the turntable 7, and the plurality of clamping assemblies 8 are fixed on the top of the turntable 7 in a ring array. This layout makes it easy to process workpieces at different positions, and the processing position can be quickly switched by rotating the turntable 7 during the processing, thereby improving the processing efficiency.

[0032] The clamping assembly 8 includes a clamping seat 81, a bidirectional screw 82 and a clamping block 83. The two ends of the bidirectional screw 82 are rotatably connected to the bearings provided on both sides of the clamping seat 81. The bottom ends of the two clamping blocks 83 are provided with threaded holes, which are respectively matched with the threads at the two ends of the bidirectional screw 82. This structural design can conveniently and accurately adjust the distance between the clamping blocks 83 by rotating the bidirectional screw 82, so that workpieces of different sizes can be firmly clamped, thereby improving the adaptability of the machine tool to different workpieces.

[0033] In the first embodiment, the support 2 is a regular quadrangular prism structure, and four linear guide rails 3 are respectively fixed to the four sides of the support 2, and processing equipment with different functions are respectively installed on the sliders 31 of the four linear guide rails 3;

[0034] Specifically, processing equipment with different functions are installed on the sliders of the four linear guides 3 respectively. This design allows each processing equipment to be flexibly moved along the linear guides 3, which is convenient for adjusting the position of the processing equipment according to specific processing requirements, and realizes the orderly execution of multiple processing processes on the same workpiece, thereby enhancing the versatility and flexibility of the machine tool.

[0035] In the second embodiment, a plurality of cushion blocks 12 are provided on the top of the box body 1, and the cushion blocks 12 are fixedly connected to the base 4, a second through hole 41 is provided in the middle of the base 4, and the inner wall of the base 4 is closely fitted with the outer wall of the internal gear slewing bearing 5, the top of the inner ring 51 of the internal gear slewing bearing 5 is fixedly connected to the bottom of the turntable 7, and a third through hole 71 is provided in the middle of the turntable 7;

[0036] Specifically, there is a gap between adjacent pads 12, which is convenient for the arrangement of some lines, pipelines, etc. In addition, the provision of the second through-port 41 and the third through-port 71 facilitates the installation of some equipment components or the passage of lines and pipelines, making the internal structure of the machine tool more regular and convenient for maintenance and operation. The top of the inner ring 51 of the internal gear slewing bearing 5 is fastened to the bottom of the turntable 7 by bolts. This connection method ensures the firmness of the connection between the turntable 7 and the internal gear slewing bearing 5, so that the turntable 7 can stably drive the workpiece to rotate during the rotation process, which is conducive to the smooth progress of the processing.

[0037] In the third embodiment, the clamping assembly 8 is provided with four groups, and the bottom of the four groups of clamping assemblies 8 are provided with corresponding cross modules 9, and the cross modules 9 are used to adjust the position of the clamping assembly 8 in the X-axis direction and the Y-axis direction. The upper module slider 91 in the cross module 9 is fastened to the bottom of the clamping seat 81 by bolts, and a limit block 84 is provided on the top of the clamping seat 81. Two limit slots 841 corresponding to the threads at both ends of the bidirectional screw 82 are opened on the top of the limit block 84, and the limit slots 841 are located directly above the bidirectional screw 82, and the inner wall of the limit slot 841 is in a close-fitting sliding fit with the outer wall of the clamping block 83;

[0038] Specifically, the two linear motion modules of the cross module 9 are in a cross shape, wherein the upper module slider is fastened to the bottom of the clamp seat 81 by bolts, which enables the clamp seat 81 to move along with the cross module 9 in the X-axis and Y-axis directions. For the clamping assembly 8, since its position can be flexibly adjusted by the cross module 9, when it is necessary to clamp workpieces of different sizes and shapes, the cross module 9 can be used to accurately move the clamping assembly 8 to the appropriate position. Moreover, during the processing, if different parts of the workpiece need to be processed, the position of the clamping assembly 8 can be adjusted by the cross module 9. The position change of the workpiece in the plane can be achieved without re-disassembling and re-installing the workpiece. The setting of the limit block 84 can ensure that the clamping block 83 always maintains the correct direction during the movement to prevent it from being offset or skewed, further ensuring the stability and accuracy of the workpiece clamping, which is conducive to improving the processing quality.

[0039] Working principle:

[0040] First, in the workpiece clamping process, the position of the clamping assembly 8 is adjusted by the movement of the cross module 9 in the X-axis and Y-axis directions. Since one module in the cross module 9 is responsible for the X-axis movement and the other is responsible for the Y-axis movement, the module slider above it is fastened with the bottom bolts of the clamp seat 81, so that the clamp seat 81 can move accurately in the plane. After moving the clamp seat 81 to a suitable position, the bidirectional screw 82 in the clamping assembly 8 is rotated. Since the bidirectional screw 82 is rotatably connected with the bearings on both sides of the clamp seat 81, and the threaded holes at the bottom ends of the two clamping blocks 83 are threadedly adapted to the bidirectional screw 82, at the same time, under the guiding and limiting action of the limit block 84 at the top of the clamp seat 81 and the limit slot 841 on the clamping block 83, the two clamping blocks 83 move relative to or away from each other, thereby stably clamping workpieces of different sizes;

[0041] Secondly, in terms of adjustment of the processing position, the processing equipment with different functions installed on the sliders of the linear guide rails 3 on the four sides of the pillar 2 can be flexibly moved along the linear guide rails 3, and their positions can be adjusted according to the processing requirements. At the same time, the internal gear slewing bearing 5 in the base 4 works under the drive of the motor 6, and the driving gear 61 at the top output end of the motor 6 is meshed with the gear ring 511 of the inner ring 51 of the internal gear slewing bearing 5, driving the inner ring 51 of the internal gear slewing bearing 5 to rotate, thereby rotating the turntable 7 fastened to the top thereof, and the clamping components 8 and the clamped workpiece distributed in a ring array on the turntable 7 rotate accordingly, so that different parts of the workpiece can be adjusted to the action range of the processing equipment;

[0042] Finally, during the processing, various processing equipment starts to work. During processing, the linear guide 3 can be used to move the processing equipment, the turntable 7 can be used to rotate the workpiece, and the cross module 9 can be used to adjust the position of the clamping component 8 again. The coordinated cooperation of other operations allows the workpiece to be processed in a suitable posture in three-dimensional space. Since the overall structure of the machine tool is stable, including the box 1 supporting the base 4 through the pad 12 and the fastening connection between the various components, the vibration and error in the processing process are effectively reduced, and the processing accuracy is ensured, thereby realizing all-round, multi-process efficient and precise processing of the workpiece. At this point, the entire workflow is completed.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments.

[0046] It is apparent to those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and the changes still fall within the protection scope of the invention.
