DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] like Figures 1-17 As shown: A multi-channel machining center includes a base 6, three sets of vertical frames 1 are set on the base 6, and a top seat 101 is fixed on the top of each vertical frame 1. The tool magazine 2 is hinged to the front end of the top seat 101 through a hinge block 213 set by its own connecting arm 203. The tool disk 201 of the tool magazine 2 is surrounded by a plurality of tools 3 elastically clamped by tool clamps 204. A tool cover 208 is fixed above the tool clamps 204. The back plate 202 of the tool magazine 2 is formed with an opening. The vertical frame 1 is provided with a movable The lifting seat 4 is located above the opening of the tool magazine 2; when the lifting seat 4 moves downward, the tool magazine 2 will swing outward, and a tool 3 located at the opening can be separated from the tool magazine 2 and assembled on the main shaft 5 of the lifting seat 4. The tool 3 can adjust its own height up and down through the lifting seat 4 to approach the processing table 8 that can be moved forward and backward or left and right in front of the stand 1. After being driven to rotate by the spindle motor 501, the tool 3 can perform processing actions such as cutting, drilling, and tapping on the workpiece placed on the processing table 8.

[0040] Furthermore, the tool disc 201 can rotate relative to the tool magazine 2 as a whole to switch the designated tool 3 to move to the opening to be combined with the spindle 5. Figure 2-Figure 8 As shown, the above-mentioned connecting arm 203 of the tool magazine 2 is equipped with a fixed shaft 223, and the cutter disc 201 is rotatably sleeved on the fixed shaft 223 through a bearing. A connecting seat 205 is provided at the end of the fixed shaft 223 away from the connecting arm 203. The fixed shaft 223 is locked and fixed to the middle part of the connecting seat 205 by means of fasteners. A cutter disc motor 215 and a worm 225 are respectively installed at both ends of the connecting seat 205, and the two are driven by a synchronous wheel 235 and a synchronous belt 245 arranged on the side of the connecting seat 205. When the worm 225 is driven to rotate by the cutter disc motor 215, the rotor 206 locked on the cutter disc 201 can be driven and cooperated with it through the roller 216 provided by itself, thereby driving the cutter disc 201 to rotate.

[0041] Specifically, a boss 211 is formed in the center of the above-mentioned cutter disc 201, and the cutter disc shaft 221 extending upward from the boss 211 is used to be socketed and combined with the fixed shaft 223. The cutter disc shaft 221 is formed with a plurality of ribs on the side, and the rotor 206 is locked above the ribs with the help of fasteners, thereby achieving mutual fixation with the cutter disc 201. At the same time, since the connecting seat 205 for installing the above-mentioned cutter disc motor 215 and worm gear 225 is locked at the front end of the fixed shaft 223, the front end of the fixed shaft 223 is loaded with a large load, and the entire drive device is prone to falling risk. Therefore, a sleeve 207 is fixedly provided at the boss 211 in the center of the cutter disc 201. The sleeve 207 is mutually engaged with a chip guard plate 255 locked at the rear side of the connecting seat 205 for preventing processing debris from splashing onto the cutter disc 201. If this is done, without affecting the rotation of the tool magazine 2, the sleeve 207 can use the chip guard plate 255 to assist in supporting the driving part at the front end of the fixed shaft 223, share some pressure, and thus reduce the above-mentioned falling risk.

[0042] Specifically, an outer cover 265 is fixed to the front side of the connecting seat 205. The outer cover 265 and the chip guard plate 255 can form a chamber together to protect the cutter motor 215 and the worm 225 to reduce the erosion caused by dust and debris. At the same time, the edges of the outer cover 265 and the chip guard plate 255 are correspondingly formed with edging and flanges. The edging of the outer cover 265 is also separated from the cutter cover 208 by a certain gap. Figure 7 As shown, due to the presence of the edging and the flange, a larger concave cavity is formed between the edge of the chamber and the knife cover. When inspecting the cutter motor 215 and related drive components, the human hand can grasp the edge of the outer cover 265 more stably through the concave cavity, thereby avoiding the impact on other components caused by its own weight after removal.

[0043] Specifically, the outer sides of the synchronous wheel 235 and the synchronous belt 245 are also protected by a synchronous belt guard 275 provided on the side of the connecting seat 205. Of course, the synchronous belt guard 275 is also provided with an avoidance groove on the side close to the rotor 206 to avoid interference with the rotor 206.

[0044] Furthermore, the swing of the tool magazine 2 is achieved by a guide plate 401 fixed laterally to the lifting seat 4, as shown in FIG. Figures 9-11 As shown, the guide plate 401 is formed with two guide surfaces 411 at the upper and lower parts. The guide surface 411 at the lower part is arranged in a Z-shaped curve, and the guide surface 411 at the higher part is a slope with a lower slope. The connecting arm 203 of the tool magazine 2 has an ear 233, and the guide wheel 243 installed on the ear 233 can fit the two guide surfaces 411 of the guide plate 401 and cooperate with each other. When the spindle 5 of the lifting seat 4 is combined with the designated tool 3 of the tool magazine 2 and moves downward, the guide wheel 243 first cooperates with the Z-shaped guide surface 411, so that the tool magazine 2 can immediately swing outward to a large extent so that the tool 3 can be separated from the tool clamp 204. During the subsequent movement of the lifting seat 4, the guide wheel 243 cooperates with the guide surface at the upper part of the guide plate 401, so that the tool magazine 2 only has to swing slightly to avoid the lifting seat 4; conversely, when the lifting seat 4 moves upward and needs to return the designated tool 3 combined with its spindle 5 to the tool magazine 2, the guide wheel 243 cooperates with the Z-shaped guide surface 411, so that the tool magazine 2 can immediately swing inward to a large extent. At this time, the tool clamp 204 will be elastically stretched open by the tool 3 on the spindle 5, so that the tool 3 can be clamped back to its position.

[0045] Further, such as Figure 8 、 Figure 14-15 As shown, a number of protrusions 231 are formed at equal intervals on the outer edge of the cutter disc 201, and adjacent protrusions 231 together form a limiting groove. The tool holder 204 has a clamping rod 214 with a bent design. The end of the clamping rod 214 is installed in the limiting groove and is fixed to the cutter disc 201 by a number of fasteners. The other end is hinged with two clamping arms 224. The two clamping arms 224 are elastically opened and closed by clamping arm springs, and each clamping end is equipped with a clamping wheel 234 that matches the clamping groove of the tool 3; when the tool is When the magazine 2 is driven to swing outward or inward by the above-mentioned guide plate 401 of the lifting seat 4, the clamping wheel 234 of the corresponding tool clamp 204 used to cooperate with the designated tool 3 of the spindle 5 can cooperate with the clamping groove of the tool 3, thereby forcing the clamping arm 224 to open. When the lifting seat 4 moves downward, the clamping arm 224 opens to allow the designated tool 3 to be detached from the tool magazine 2, and the tool 3 can approach the workpiece to be processed with the spindle 5. When the lifting seat 4 moves upward, the clamping arm 224 opens to allow the designated tool 3 on the spindle 5 to be re-clamped and returned to the tool magazine 2.

[0046] Specifically, the inner edge of the knife cover 208 is provided with a plurality of fastening holes corresponding to the clamping rod 214 of the knife clamp 204, and the fasteners can pass through the fastening holes and be connected to the knife clamp 204, so that the knife cover 208 and the knife clamp 204 are fixed to each other; of course, in the present design, the fasteners used to fix the clamping rod 214 to the knife disc 201 and the fasteners used to fix the knife cover 208 can be the same or different fasteners, but are preferably different fasteners to avoid affecting the disassembly and assembly of each other.

[0047] Furthermore, the above-mentioned base 6 has two sets of Y-axis boss seats arranged in parallel for installing the Y-axis line rail, and a saddle 7 can be translated back and forth relative to the base 6 through the Y-axis line rail. The saddle 7 itself has two sets of X-axis boss seats arranged in parallel for installing the X-axis line rail, and the above-mentioned processing table 8 on which the workpiece can be placed can be translated left and right relative to the saddle 7 through the X-axis line rail.

[0048] Specifically, a drainage groove 601 is formed between the two groups of Y-axis bosses on the base 6. The drainage groove 601 is tilted toward the rear of the base 6 so that waste liquid generated during the processing can be discharged to the outside of the equipment.

[0049] Furthermore, the translational movement of the above-mentioned lifting seat 4, saddle 7, and processing table 8 is achieved by a screw rod 9 in combination with a screw motor 902. The lifting seat 4, saddle 7, and processing table 8 are each provided with a clamping ring 903. The clamping ring 903 can clamp the threaded block 901 on the corresponding screw rod 9 to drive the lifting seat 4, saddle 7, and processing table 8 to perform translational movement with the help of the threaded cooperation between the screw rod 9 and the threaded block 901.

[0050] Specifically, the above-mentioned screw motor 902 has a motor base 904, and its motor shaft and screw 9 respectively penetrate into the inner cavity of the motor base 904 from both sides of the motor base 904, and are connected to each other through claw plates 905 at the ends. The two connected claw plates 905 are jointly clamped with elastic plum blossom-shaped gaskets 906, and the gaskets 906 can fill the gaps between the claw plates 905; when the motor shaft rotates, it can drive the screw 9 to rotate through the claw plates 905. The presence of the gasket 906 can absorb the vibration generated during the rotation of the motor shaft, so that the screw 9 can drive more smoothly.

[0051] Specifically, the above-mentioned stand 1, base 6, and saddle 7 can also form a mounting platform on themselves for embedding the motor seat 904 of the corresponding screw motor 902. The motor seat 904 is locked with the mounting platform by the wing plates formed on both sides of itself. Of course, in order to avoid obstruction of the discharge of waste liquid from the drainage trough 601, the mounting seat provided on the base 6 can also be provided with a number of through drainage holes 602.

[0052] Furthermore, the above-mentioned main shaft 5 of the lifting seat 4 is combined and fixed with the designated tool 3 on the tool magazine 2 through its own four-petal claw structure. The main shaft 5 has a knife-beating arm 502 hingedly arranged relative to the lifting seat 4, and the top seat 101 is fixed with a bump block 111 with an arc surface. The roller 512 at the end of the knife-beating arm 502 can cooperate with the bump block 111 to control the main shaft 5 to achieve clamping or loosening of the designated tool 3. Of course, the knife-beating arm 502 can also be elastically connected to the lifting seat 4 through a knife-beating arm spring (not shown in the figure) to achieve its own resetting action (the knife-beating arm 502 belongs to the existing technology, and its specific principle is not described in detail in this article).

[0053] Furthermore, the fixed installation between the above components can be achieved by using various types of screws as fasteners.

[0054] The operation mode of this design is roughly the same as the existing technology. Simply put, it is to first switch the specified tool through the tool disc motor and move it to the opening of the tool magazine. After the lifting seat moves down to combine with the tool, it continues to move downward to drive the tool magazine to swing outward. The tool will be detached from the tool magazine and can be used to process the workpiece on the processing table as the spindle rotates.

[0055] It is understood that the present invention is described by some embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the guidance of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.

[0056] Therefore, the present invention is not limited to the specific embodiments disclosed herein.

[0057] All embodiments falling within the scope of the claims of this application are protected by the present invention.
