Description

Technical Field

[0001] This utility model relates to the field of machining center technology, and in particular to a machining center capable of multi-directional machining. Background Technology

[0002] In the field of machining, machining centers, as automated equipment integrating multiple machining functions such as milling, boring, and drilling, are widely used in the processing of various precision parts. The spindle layout of machining centers is mostly vertical, with its spindle direction fixed and always perpendicular to the worktable. This structure can efficiently and stably complete the operation when machining the upper surface of the workpiece. However, when machining the side of the workpiece is required, the operator usually needs to remove the workpiece from the clamping device, readjust the clamping direction, and then clamp it again. In addition, the tool needs to be re-set to determine the relative position of the tool and the workpiece. This is not only cumbersome and time-consuming, reducing machining efficiency, but also the repeated clamping and tool setting operations can easily introduce positioning errors, leading to a decrease in machining accuracy. Frequent disassembly of the workpiece may also cause damage to the workpiece surface, affecting product quality. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] In view of the problems existing in the above and / or existing machining centers capable of multi-directional processing, this utility model is proposed.

[0005] Therefore, the problem that this utility model aims to solve is that the machining center, due to the fixed spindle direction, requires frequent changes in clamping direction and re-tool setting when machining the side of the workpiece, which is complicated and reduces machining efficiency.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a machining center capable of multi-directional machining. The multi-directional machining center includes a main component 100, including a frame 101. A spindle box 102 is provided on the frame 101. A flange 103 is fixed to the bottom of the spindle box 102. A clamping mechanism 104 is provided inside the spindle box 102. A spindle is provided inside the spindle box 102. The clamping mechanism 104 uses hydraulic clamping to clamp the chuck of the tool holder, so that the rotation of the spindle can drive the rotation of the tool head. The lifting and translation of the spindle box 102 are CNC controlled and can move precisely. This is prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0032] A reversing seat 105 is provided on one side of the frame 101. A set of bevel gears is provided inside the reversing seat 105 to change the transmission direction. Through the engagement of the bevel gears, the vertical rotational motion of the main shaft is changed into a rotational motion parallel to the ground. A side cutter 106 is provided on one side of the reversing seat 105. There are two mutually perpendicular rotating shafts inside the reversing seat 105. One end of the rotating shaft perpendicular to the ground is the same as the tool holder chuck. Therefore, the main shaft in the spindle box 102 can be rotated through the clamping mechanism 104, which can drive the rotating shaft perpendicular to the ground in the reversing seat 105 to rotate. Through the bevel gears, the rotating shaft parallel to the ground in the reversing seat 105 is driven to rotate. This shaft is connected to the side cutter 106, thereby driving the side cutter 106 to rotate. In this way, the two end faces of the workpiece near the frame 101 can be processed.

[0033] When the spindle inside the spindle box 102 rotates, the outer casing of the reversing seat 105 does not rotate; only the internal rotating shaft and bevel gear rotate. This is existing technology, and this solution will not elaborate further. Moreover, those skilled in the art can clearly understand the working principle.

[0034] A worktable 107 is provided below the frame 101. The workpiece is placed on the worktable 107, which is a magnetic table surface. The workpiece is fixed by magnetic attraction and will not obstruct the side of the workpiece, thus facilitating the processing of the side of the workpiece. This is existing technology and will not be described in detail here. Moreover, those skilled in the art can clearly understand the working principle.

[0035] Mounting assembly 200, located below spindle box 102, includes mounting component 201 for connecting spindle box 102 to reversing seat 105, thereby transmitting the rotational motion of the spindle to side tool 106 for machining the side of workpiece.

[0036] Mounting component 201 includes a mounting plate 2011 fixed to the top of the reversing seat 105. The mounting plate 2011 has a through hole 2011-1. A fixing pin 2012 and a fixing post 2013 are fixed on the flange 103. The arrangement of these two components ensures that the rotating shaft perpendicular to the ground inside the reversing seat 105 can be collinear with the spindle located in the spindle box 102. The fixing pin 2012 and the fixing post 2013 can be inserted into the through hole 2011-1.

[0037] The reversing seat 105 is initially positioned away from the worktable 107. The position of the spindle box 102 is adjusted until the flange 103 and the fixed plate 2011 are coaxial. Then, the spindle box 102 is lowered, and the fixed pin 2012 and the fixed column 2013 are lowered synchronously and enter the through hole 2011-1. Then, the clamping mechanism 104 is activated to clamp the top of the vertical shaft in the reversing seat 105 and connect the internal rotating shaft.

[0038] Example 2

[0039] Reference Figures 6-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the mounting assembly 200 also includes a locking element 202 located on one side of the fixing post 2013. The locking element 202 is used to lock the relative position of the flange 103 and the fixing plate 2011, and to assist in connecting the spindle box 102 and the reversing seat 105, so as to prevent the reversing seat 105 from falling directly and being damaged in the event of an accidental failure of the clamping mechanism 104.

[0041] The locking component 202 includes a cylinder 2021 fixed to a fixing post 2013, a first annular block 2022 fixed on the cylinder 2021, and a second annular block 2023 sleeved on the cylinder 2021. The second annular block 2023 can slide on the cylinder 2021, so the relative position between the first annular block 2022 and the second annular block 2023 can be changed.

[0042] Specifically, a first moving groove 2011-2 is provided on the fixed plate 2011, and a locking block 2024 is slidably arranged in the first moving groove 2011-2. The locking block 2024 is used to lock the relative position of the fixed plate 2011 and the flange 103. The first moving groove 2011-2 is connected to the through hole 2011-1, and two locking blocks 2024 are symmetrically arranged on both sides of the through hole 2011-1.

[0043] A first spring 2025 is fixed on one side of the locking block 2024, and the other end of the first spring 2025 is fixed in the first moving groove 2011-2. The first spring 2025 applies a continuous pushing force to the locking block 2024, so that a part of the locking block 2024 always protrudes into the through hole 2011-1. When the locking block 2024 is located between the first annular block 2022 and the second annular block 2023, the fixed plate 2011 and the flange 103 cannot be separated.

[0044] Specifically, the fixed column 2013 has a sliding groove 2013-1, and a second spring 2026 is installed in the sliding groove 2013-1. The two ends of the second spring 2026 are fixed to the second annular block 2023 and the inner wall of the sliding groove 2013-1, respectively. The second spring 2026 applies a continuous pulling force to the second annular block 2023 to ensure that the second annular block 2023 will not move downward due to its own weight when no other external force is applied.

[0045] Specifically, the first annular block 2022 and the second annular block 2023 have inclined surfaces with opposite inclination angles. When the two are fitted together, their inclined surfaces will join together to form a pointed tip.

[0046] Example 3

[0047] Reference Figures 4-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0048] Specifically, one end of the locking block 2024 is inclined. This inclination ensures that the shaft perpendicular to the ground within the reversing seat 105 is collinear with the main shaft located within the main spindle box 102. When the main spindle box 102 descends, the fixing pin 2012 and fixing column 2013 descend synchronously and enter the through hole 2011-1. The fixing column 2013 then moves the cylinder 2021, the first annular block 2022, and the second annular block 2023 synchronously into the through hole 2011-1. At this point, the inclined end face of the locking block 2024 first contacts the inclined surface of the first annular block 2022. The first annular block 2022 presses against the locking block 2024, compressing the first spring 2025 and locking the lock. Block 2024 will not obstruct the first annular block 2022 from continuing to descend. As the spindle box 102 descends, it drives the first annular block 2022 to continue to descend. When the first annular block 2022 no longer presses against the locking block 2024, the first spring 2025 resets, causing the locking block 2024 to move between the first annular block 2022 and the second annular block 2023. At this time, the movement of the spindle box 102 stops, and the upper end face of the first annular block 2022 will fit against the lower end face of the locking block 2024, thereby preventing the fixed plate 2011 and the flange 103 from separating. Then, the clamping mechanism 104 is activated to clamp the top of the vertical shaft in the reversing seat 105 and connect the internal rotating shaft.

[0049] Specifically, a rubber pad 2027 is fixed on the fixed plate 2011, and a through hole 2011-1 is also opened on the rubber pad 2027. The setting of the rubber pad 2027 allows the distance between the fixed plate 2011 and the flange 103 to be changed.

[0050] When it is necessary to separate the fixed plate 2011 from the flange 103, first release the clamping mechanism 104 to cut off the internal rotating shaft connection, and then control the spindle box 102 to move downward a short distance. Since the bottom of the reversing seat 105 is restricted from moving downward, the rubber pad 2027 will be compressed, and the fixed column 2013 will continue to descend, driving the cylinder 2021, the first annular block 2022 and the second annular block 2023 to descend. The end face of the second annular block 2023 will press against the inclined surface of the locking block 2024, thereby compressing the first spring 2025. The locking block 2024 will not hinder the descent of the second annular block 2023. When the lower end face of the second annular block 2023 separates from the lower end face of the locking block 2024, the first spring 2025 returns to its original state, and the locking block 2024 moves between the second annular block 2023 and the fixed column 2013.

[0051] Then, the spindle box 102 is controlled to move upward. Since the elastic force of the first spring 2025 is greater than that of the second spring 2026, the locking block 2024 will hinder the upward movement of the second annular block 2023, causing the second annular block 2023 to stretch. The second annular block 2023 slides downward along the cylinder 2021 relative to the fixed post 2013, so that the second annular block 2023 and the first annular block 2022 are in contact. The spindle box 102 continues to move upward. At this time, the first annular block 2022 will drive the second annular block 2023 to move upward. The inclined surface of the second annular block 2023 will squeeze the locking block 2024, causing the first spring 2025 to be compressed again, without hindering the upward movement of the second annular block 2023 and the first annular block 2022, thereby separating the fixed post 2013 from the through hole 2011-1.

[0052] Specifically, there are four sets of fixing pins 2012 and four sets of fixing posts 2013, which are staggered.

[0053] Specifically, it also includes a support assembly 300 for supporting the reversing seat 105, located on one side of the frame 101, including a placement frame 301, which is fixed to the frame 101 by multiple connecting rods. A support plate 302 is fixed on the placement frame 301. The placement frame 301 has slots 301-1 on both sides, the size of which corresponds to the side cutter 106, and the size of the reversing seat 105 corresponds to the inner wall size of the placement frame 301. The reversing seat 105 can be locked in the placement frame 301, thereby ensuring that the center position of the reversing seat 105 is the same each time it is placed, which facilitates connection with the spindle box 102. At the same time, the placement direction of the reversing seat 105 can be adjusted according to the position to be processed, thereby adjusting the direction of the side cutter 106 to meet the processing requirements.

[0054] Supporting columns 303 are fixed on the supporting plate 302. There are four supporting plates 302. When the reversing seat 105 is placed in the placement frame 301, the bottom of the fixing plate 2011 will contact the upper end of the supporting column 303, thereby supporting the reversing seat 105.

[0055] Specifically, a control mechanism 108 is provided on one side of the frame 101. The control mechanism 108 is used to control the position of the spindle box 102 and the rotation of the internal spindle. It can also control the clamping mechanism 104. This is prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0056] In use, when the upper surface of the workpiece is machined and the two end faces of the workpiece near the frame 101 need to be machined, the tool head originally located at the bottom of the spindle box 102 is first removed by the clamping mechanism 104. Then, the control mechanism 108 is operated to move the spindle box 102 directly above the placement frame 301, and the rotating shaft perpendicular to the ground in the reversing seat 105 is collinear with the spindle located in the spindle box 102. Then, the spindle box 102 is controlled to descend, and the fixing pin 2012 and the fixing post 2013 descend synchronously and enter the through hole 2011-1. At this time, the inclined end face of the locking block 2024 will first contact the inclined surface of the first annular block 2022. The first annular block 2022 squeezes the locking block 2024, causing the first spring 2025 to be compressed, and the lock... The fixed block 2024 will not obstruct the first annular block 2022 from continuing to descend. As the spindle box 102 descends, it drives the first annular block 2022 to continue to descend. When the first annular block 2022 no longer presses against the locking block 2024, the first spring 2025 resets, causing the locking block 2024 to move between the first annular block 2022 and the second annular block 2023. At this time, the movement of the spindle box 102 stops, and the upper end face of the first annular block 2022 will fit against the lower end face of the locking block 2024, thereby preventing the fixed plate 2011 and the flange 103 from separating. Then, the clamping mechanism 104 is activated to clamp the top of the vertical shaft in the reversing seat 105 and connect the internal rotating shaft. Then, the spindle box 102 is moved to the corresponding position to complete the side processing of the workpiece.

[0057] When it is necessary to separate the fixed plate 2011 and the flange 103, adjust the position of the spindle box 102 so that the reversing seat 105 is located inside the placement frame 301. Then, first release the clamping mechanism 104 to disconnect the internal rotating shaft connection. Then, control the spindle box 102 to move downward a short distance. Since the bottom of the reversing seat 105 is restricted from moving downward, the rubber pad 2027 will be compressed, the fixed column 2013 will continue to descend, and the end face of the second annular block 2023 will press against the inclined surface of the locking block 2024, thereby compressing the first spring 2025. The locking block 2024 will not hinder the descent of the second annular block 2023. When the lower end face of the second annular block 2023 separates from the lower end face of the locking block 2024, the first spring 2025 returns to its original state, and the locking block 2024 moves between the second annular block 2023 and the fixed column 2013.

[0058] Then, the spindle box 102 is controlled to move upward. Since the elastic force of the first spring 2025 is greater than that of the second spring 2026, the locking block 2024 will hinder the upward movement of the second annular block 2023, causing the second annular block 2023 to stretch. The second annular block 2023 slides downward along the cylinder 2021 relative to the fixed column 2013, so that the second annular block 2023 and the first annular block 2022 are in contact. The spindle box 102 continues to move upward. At this time, the first annular block 2022 will drive the second annular block 2023 to move upward. The inclined surface of the second annular block 2023 will squeeze the locking block 2024, causing the first spring 2025 to be compressed again, without hindering the upward movement of the second annular block 2023 and the first annular block 2022. This separates the fixed column 2013 from the through hole 2011-1, and separates the fixed plate 2011 from the flange 103, thereby completing the separation of the spindle box 102 and the reversing seat 105.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
