[0024] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] As mentioned in the background technology, in order to solve the problems in the prior art, this application proposes a multi-station vertical honing machine tool, please refer to Figure 1 As shown, including:

[0027] A bed 7, on which a processing turntable 6 is arranged, and the processing turntable 6 is provided with a plurality of processing stations 61 for clamping a workpiece to be processed;

[0028] A mounting frame, used for mounting a spindle box 4, the spindle box 4 is mounted on the mounting frame through a lifting mechanism, the spindle box 4 is provided with a plurality of machining axes, each machining axis is equipped with a honing tool 5;

[0029] An escape space is formed between the mounting frame and the bed 7, and the processing turntable 6 is at least partially embedded in the escape space, so that the orthographic projection of the lifting axis of the lifting mechanism on the first plane is located in the central pitch circle area; the first plane is a plane perpendicular to the main axis of the spindle box 4; the central pitch circle area is the area formed by the intersection line of the central axis of all processing axes and the first plane.

[0030] In this embodiment, six machining axes are selected to be arranged on the spindle box 4 , and each machining axis can drive its own honing tool 5 to hone the workpiece to be processed in the corresponding machining station 61 below it.

[0031] Specifically, the lifting mechanism includes a screw, a sliding seat, and two lifting guide rails 33. The lifting axis refers to the screw, and in the present embodiment, the lifting mechanism adopts a screw slider structure: lifting guide rails 33 are provided on both sides of the middle of the beam, and the sliding part of the main spindle box is slidably clamped on one side of the beam through the lifting guide rails on the one hand, and is fixedly connected to the slider threaded on the screw on the other hand; the screw coaxially connected to the output shaft of the lifting motor is in the beam and is not visible in the figure; the sliding part of the main spindle box, the lifting guide rail 33, and the screw form an integrated lifting main body structure all in the center pitch circle area; in the present embodiment, the diameter of the center pitch circle area is 620 mm, and the lifting guide rail 33 and the screw are in a circle with a diameter of 440 mm in the present embodiment.

[0032] Specifically, the bed 7 is the honing machine itself, on which a rotatable processing turntable 6 is arranged. The processing turntable 6 is circular, and each of the processing stations 61 is distributed on the outer circumference of the circle. Each of the processing stations 61 has its own clamping assembly for clamping the workpiece to be processed. The workpiece to be processed is placed on the processing station 61 and fixed by the clamping assembly of the processing station 61. The hole to be honed of the workpiece to be processed is aligned with the central axis of the processing station 61. During the honing process, all the processing stations 61 can be fully filled with components to be processed, or they can be placed selectively. A control mechanism for controlling the rotation of the processing turntable 6 is also installed on the bed 7. The control mechanism controls the processing turntable 6 rotates and stops, the whole processing process is: first, by rotating the processing turntable 6, each workpiece to be processed is placed in turn in the processing station 61, and clamped by the clamping assembly. When a circle of the processing stations 61 is full, the processing turntable 6 is controlled to stop rotating. At this time, the axis of the hole to be honed of each workpiece to be processed on the processing turntable 6 is aligned with the axis of the processing axis of the corresponding honing tool 5 directly above it. At this time, the lifting mechanism drives the spindle box 4 to descend, driving all the honing tools 5 to descend. The honing tool 5 is driven to rotate by its own driving motor to hone the hole to be honed of each workpiece. After the honing of this batch of workpieces to be processed is completed, they are taken out and then processed in the same way in a cycle for the next batch of workpieces to be processed.

[0033] Since the column of the traditional vertical honing machine is a solid structure installed on the bed, the processing turntable 6 needs to be set on the bed on one side of the column, so it is necessary to use a suspended spindle box 4, only one side wall of the spindle box 4 can be slidably connected to the column 2 perpendicular to the machine tool, and the other areas are suspended from the column 2, so that the several honing tools installed on the spindle box can be aligned with the processing stations on the processing turntable. However, if it is set in this way, the distance from the processing axis of each honing tool installed on the spindle box to the lifting axis of the lifting mechanism is not equal, and the spindle box 4 with a larger dead weight is connected to the One side of the column 2 will be relatively stable, while the other protruding side will gradually sink as the use time becomes longer, causing the spindle box 4 that was originally perpendicular to the column 2 to have a certain tilt angle. Specifically, the farther away from the column 2, the more serious the sinking. This will cause the relative heights of the honing tools 5 set on the suspended spindle box to be inconsistent with the processing turntable 6. In this way, when the lifting mechanism is controlled to descend the spindle box 4 to a certain height to hone the workpiece to be processed in the processing turntable 6, the processing heights of the honing tools 5 are inconsistent, and there will be differences in the processing accuracy of this batch of workpieces to be processed, which will damage the honing effect.

[0034] In view of the defects of the prior art, the design concept of this scheme is as follows: by cleverly designing the mounting frame for mounting the spindle box 4 installed on the bed, so that it directly forms an avoidance space with the bed, the avoidance space can embed a part of the processing turntable 6 into the avoidance space, reduce the laying area of ​​the components on the bed 7, and improve the compactness of the structure, and then adaptably make the positive projection of the lifting axis of the lifting mechanism on the first plane located in the central pitch circle area, so that the distance between the center of the lifting mechanism and each processing axis is basically consistent. By mounting the spindle box 4 on the outside of the lifting mechanism on the crossbeam 1 in a surrounding and wrapped form, shortening the width of the spindle box 4 extending outward, ensuring that the extended area can be effectively supported by one side of the rigid connection, effectively avoiding the sinking phenomenon caused by the heavy weight of the spindle box 4, and the arrangement of the honing tool 5 is also uniformly distributed around the lifting axis of the lifting mechanism in a circumferential array distribution manner, ensuring that the distance from the processing axis of each honing tool 5 to the lifting axis is equal along the radial direction. In this way, even if the spindle box 4 sinks to the outside after a long time of use, each honing tool 5 is on the same outer circumference relative to the lifting axis. Figure 3 As shown, they sink to the same degree, so that the force on the machining axis of each honing tool is stable, effectively ensuring the machining accuracy. The ingenious structural design of this solution not only compacts the structure of the originally bulky and large traditional honing machine tool, but also ensures the force stability of the honing tool machining axis and improves the machining accuracy.

[0035] In a preferred embodiment, the mounting frame includes a crossbeam 1 and a column, and the crossbeam 1 is mounted on the bed 7 through the column 2; the processing turntable 6 is located slightly below one side of the crossbeam 1; the lifting mechanism includes at least a counterweight cylinder 32, and the counterweight cylinder 32 is mounted on the crossbeam 1 and is arranged on the same side of the crossbeam 1 as the processing turntable 6.

[0036] In a preferred embodiment, two columns 2 are provided, and each column 2 is provided with a mounting portion 21 on one side of the exposed surface of the machine tool. The mounting portion 21 can selectively install a reserved line body and / or a feeding mechanism 9 and / or a flipping mechanism 10. The flipping mechanism 10 is away from the feeding mechanism 9 side, and a brushing mechanism 11 is also provided on the bed 7.

[0037] In a preferred embodiment, on the inner opposite surfaces of the two columns 2, a loading robot arm 8 is provided on the column 2 on the side where the loading mechanism 9 is installed, and a unloading robot arm is provided on the column 2 on the side where the flipping mechanism 10 is installed.

[0038] In a preferred embodiment, a feeding cylinder 12 and a feeding guide rail 13 are provided on one side of the bed 7 of the brushing mechanism 11, and the feeding cylinder 12 is used to drive the workpiece to be processed after brushing to be transported along the feeding guide rail 13 to the feeding conveying line.

[0039] Specifically, the traditional honing machine tool adopts the form of a single column 2, and the spindle box 4 is suspended on one side of the single column 2. For such a solid single column 2, if the spindle box 4 fails or the honing tool 5 needs to be replaced, the maintenance and replacement personnel can only stand on both sides of the column 2 to repair the spindle box 4 and replace the tool. Such a structure causes many inconveniences to the maintenance and replacement work.

[0040] In consideration of facilitating maintenance and replacement of components, the original single column 2 of the honing machine is designed as a gate type in this application, that is, the two columns 2 are arranged opposite to each other along the fast direction of the bed 7, and the crossbeam 1 is arranged between the two columns 2. Thus, an escape space is formed between the two columns 2 and at the bottom of the crossbeam 1. Since the escape space is open at the front and back, it can provide maintenance space for maintenance and replacement personnel, which is convenient for maintenance. The escape space can also provide an escape space for the processing turntable 6 to rotate. In the prior art, since the single column 2 is a solid structure, the processing turntable 6 can only be arranged on the bed 7 on the side of the single column 2 where the spindle box 4 is suspended. In this way, the laying range will become larger. It can be understood that from a top-down perspective, please refer to Figure 3 As shown, the parts arranged on the bed 7 have a large laying range and no common area, while the door-shaped column 2 of the present application is designed so that the processing turntable 6 can be partially embedded in the avoidance space, thus reducing the laying range of the parts on the bed 7 and making the layout between the parts more reasonable.

[0041] For further information, please refer to Figure 2As shown, the two columns 2 also have the mounting portion 21, and the mounting portion 21 can be installed with a reserved line body and / or a feeding mechanism 9 and / or a turning mechanism 10 according to the working conditions. The turning mechanism 10 is away from the feeding mechanism 9 side. A brushing mechanism 11 is also provided on the bed 7. The honing machine can choose manual loading, fully automatic loading and semi-automatic loading. When manual loading and unloading are selected, there is no need to install those mechanisms on the mounting portion 21, and it can be done manually. When a process needs to be performed automatically, it is necessary to install the mechanism used in the process. For example, in order to improve the honing efficiency, it is necessary to load, turn, and clean the flow. The process is fully automatic. At this time, the feeding mechanism 9 is set on the mounting part 21 of the outer side surface of one of the columns 2, and the turning mechanism 10 is set on the mounting part 21 of the outer side surface of the other column 2. The reserved line body can be selectively set on the mounting part 21 of any column 2. On the column 2 where the feeding mechanism 9 is installed, the feeding robot arm 8 is installed in the avoidance space, and the avoidance space can provide a movement space for the feeding robot arm 8. On the column 2 where the turning mechanism 10 is installed, the unloading robot arm is installed in the avoidance space. The reserved line body is used to arrange the working line of the machine tool.

[0042] The specific processing process is as follows: the loading mechanism 9 is connected to the loading conveyor line, the loading conveyor line is used to convey the workpiece to be processed, the loading robot arm 8 grabs the workpiece to be processed from the loading mechanism 9 and places it in one of the processing stations 61, the processing turntable 6 rotates, the loading robot arm 8 grabs another workpiece to be processed and places it on the next processing station 61, and honing is performed after it is full. After honing, the unloading robot arm grabs the honed workpiece to be processed in the processing station 61 and places it on the flipping mechanism 10. The flipping mechanism 10 flips the workpiece to be processed 180 degrees and then directly turns it to the brushing mechanism 11. After the brushing mechanism 11 processes the edge burrs and chamfers, the cleaned workpiece to be processed is conveyed to the unloading conveyor line along the unloading guide rail 13 through the unloading cylinder 12 and the unloading guide rail 13, completing the whole process.

[0043] It can be seen from the above processing that the operation process of the honing machine is relatively complicated, so there are also many necessary installation mechanisms. The existing technology usually installs components such as the reserved line body, the feeding mechanism 9, the turning mechanism 10, the brushing mechanism 11, the feeding robot arm 8, and the unloading robot arm on the bed 7, and spreads them out on the bed 7. This will cause the machine tool to be very large due to the dispersed structure layout, and the compatibility of the machine tool is poor. The door-shaped column 2 designed in this application can be set on the columns 2 on both sides, and these necessary mechanisms are separated from the bed 7. These mechanisms originally set in the extension direction of the bed 7 are arranged in the vertical direction, which optimizes the overall honing machine structure, makes the structure more compact, and reduces the size of the machine tool.

[0044] In a preferred embodiment, the lifting mechanism further includes a driving motor 31 and a lifting guide rail 33 . The driving motor 31 is used to drive the lifting shaft to rotate. The lifting shaft rotates and drives the spindle box 4 to move up and down along the lifting guide rail 33 .

[0045] Due to the heavy weight of the spindle box 4, the load of the drive motor 31 is too large if it is driven by the drive motor 31 to lift the spindle box 4. Therefore, the counterweight cylinder 32 is provided to reduce the load of the drive motor 31. The piston rod of the counterweight cylinder 32 is not shown in the figure. The piston rod should be connected to the boss 41 in the middle of the spindle box 4. The position of the boss 41 is the heaviest part of the spindle box 4 for the drive motor 31. The counterweight cylinder 32 is provided here for the best counterweight effect. Therefore, the counterweight cylinder 32 needs to adapt to the position of the spindle box 4.

[0046] Please refer to Figure 1 As shown, in this embodiment, the spindle box 4 is arranged on one side of the beam 1, and the corresponding counterweight cylinder 32 and the processing turntable 6 are also arranged on the same side. The processing turntable 6 is arranged below the beam 1. A part of the processing turntable 6 may fall into the avoidance space, or it may not fall into the avoidance space at all, which is determined by the area size of the processing turntable 6 that adapts to the spindle box 4.

[0047] In a preferred embodiment, the processing turntable 6 is disposed between the two upright columns 2 and directly below the crossbeam 1 ; the counterweight cylinder 32 is disposed directly above the crossbeam 1 .

[0048] In this embodiment, another setting form of the spindle box 4 is proposed. This form requires that the column 2 has a certain height, and the crossbeam 1 is higher than the bed 7. The spindle box 4 is arranged in the avoidance space directly below the crossbeam 1. At this time, the lifting mechanism is located in the center area of ​​the center pitch circle. If the height permits, it is the optimal arrangement scheme. In this embodiment, the honing tools 5 are subjected to very uniform force and the processing height is completely consistent, which improves the processing accuracy of the honing machine.

[0049] In a preferred embodiment, the crossbeam 1 and the column 2 are integrally formed, and the column 2 is mounted on the bed 7 .

[0050] Specifically, the cross beam 1 and the column 2 can be integrally formed, and the cross beam 1 and the bed 7 can be connected and fixed by installing the column 2 on the bed 7 .

[0051] In a preferred embodiment, the crossbeam 1, the column 2 and the bed 7 are integrally formed.

[0052] Specifically, the crossbeam 1, the column 2 and the bed 7 may also be integrally formed to enhance the overall rigidity.

[0053] In a preferred embodiment, weight-reducing holes are provided on both the upright column 2 and the cross beam 1 .

[0054] Specifically, the weight-reducing holes are formed integrally when processing the upright column 2 and the cross beam 1 , and the weight-reducing holes are used to reduce the dead weight of the upright column 2 and the cross beam 1 .

[0055] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and its core ideas of this application. The above is only the preferred implementation method of this application. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the scope of protection of this application.
