Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-12 As shown: A tool magazine swing mechanism for a drilling and tapping machine includes a frame 1 and a tool magazine 2. A top seat 102 is fixed on the top of the frame 1. The tool magazine 2 is hinged to the front end of the top seat 102 via a hinge block 213 on its connecting arm 203. The tool disc 201 of the tool magazine 2 is surrounded by several tools 3. Its back plate 202 forms an opening. A vertically movable lifting seat 4 provided on the frame 1 is located above the opening of the tool magazine 2. When the lifting seat 4 moves downward, the tool magazine 2 can swing. A tool 3 located at the opening can detach from the tool magazine 2 and combine with the spindle 5 of the lifting seat 4. The tool 3 can approach the workpiece to be processed under the action of the lifting seat 4 and perform processing by rotating the spindle motor 501.

[0032] Furthermore, the swinging of the tool magazine 2 is achieved by a guide plate 402 that is laterally fixed to the lifting base 4, as shown above. Figure 2 As shown, the guide plate 402 has two guide surfaces 412, one at the bottom and one at the top. The guide surface 412 at the bottom is arranged in a Z-shaped curve, while the guide surface 412 at the top is a slope with a lower gradient. The connecting arm 203 of the tool magazine 2 has an ear 233. The guide wheel 243 installed on the ear 233 can fit against the two guide surfaces 412 of the guide plate 402 and cooperate with them. When the main shaft 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 412, so that the tool magazine 2 can immediately swing with a large amplitude so that the tool 3 can be disengaged from the tool holder 204. During the subsequent movement of the lifting seat 4, the guide wheel 243 cooperates with the guide surface at the top of the guide plate 402, so that the tool magazine 2 only swings with a small amplitude to avoid the lifting seat 4.

[0033] Furthermore, the aforementioned tool 3 is clamped by the tool holder 204 on the tool magazine 2's tool head 201, and thus mounted on the tool head 201 for selection by the spindle 5. For example... Figures 10-12 As shown, the cutter head 201 has several protrusions 211 evenly spaced along its outer edge, and adjacent protrusions 211 together form a limiting groove. The cutter clamp 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 head 201 by several fasteners. The other end is hinged to 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 cutter 3. When the cutter... When the tool magazine 2 swings outward or inward due to the guide plate 402 of the lifting seat 4, the clamping wheel 234 of the corresponding tool holder 204 of the tool holder 3 used to cooperate with the tool 3 can cooperate with the clamping groove of the tool 3, thereby forcing the clamping arm 224 to open. When the lifting seat 4 moves down, the opening of the clamping arm 224 can allow the designated tool 3 to disengage from the tool magazine 2. The tool 3 can move closer to the workpiece to be processed along with the spindle 5. When the lifting seat 4 moves up, the opening of the clamping arm 224 can allow the designated tool 3 on the spindle 5 to be clamped again and return to the tool magazine 2.

[0034] Specifically, a blade cover 208 is provided above the plurality of blade clips 204 arranged around the outer edge of the cutter head 201. The inner edge of the blade cover 208 has a plurality of fastening holes that correspond to the clamping rods 214 of the blade clips 204. Fasteners can pass through the fastening holes and connect to the blade clips 204 so that the blade cover 208 and the blade clips 204 are fixed to each other. Of course, in this design, the fasteners used to fix the clamping rods 214 to the cutter head 201 and the fasteners used to fix the blade cover 208 can be the same or different fasteners, but it is preferred that they are different fasteners to avoid affecting the disassembly and assembly of each other.

[0035] Furthermore, the aforementioned tool turret 201 can rotate relative to the tool magazine 2 as a whole to switch the designated tool 3 to the opening for combination with the spindle 5. For example... Figures 6-9 As shown, the tool magazine 2 has a fixed shaft 223 installed on the connecting arm 203. The tool disc 201 is rotatably mounted on the fixed shaft 223 via bearings. 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 to the middle of the connecting seat 205 by means of fasteners. A tool disc motor 215 and a worm gear 225 are respectively installed at both ends of the connecting seat 205. The two are driven by the synchronous pulley 235 and the synchronous belt 245 arranged laterally on the connecting seat 205. When the worm gear 225 is driven to rotate by the tool disc motor 215, the rotor 206 locked on the tool disc 201 can be driven to rotate by its own rollers 216.

[0036] Specifically, a boss 221 is formed at the center of the cutter head 201. The cutter head shaft 231 extending upward from the boss 221 is used to be sleeved and combined with the fixed shaft 223. Several ribs are formed laterally on the cutter head shaft 231. The rotor 206 is locked above the ribs by means of fasteners, thereby achieving mutual fixation with the cutter head 201. Meanwhile, since the connecting seat 205 for mounting the aforementioned cutter head 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 under a large load, and the entire drive unit is prone to falling. Therefore, a sleeve 207 is also fixedly fitted at the boss 221 at the center of the cutter head 201. The sleeve 207 is fitted with a chip baffle 255 locked behind the connecting seat 205 to prevent machining debris from splashing onto the cutter head 201. If this is done, without affecting the rotation of the tool magazine 2, the sleeve 207 can use the chip baffle 255 to provide auxiliary support to the drive part at the front end of the fixed shaft 223, sharing some of the pressure, thereby reducing the aforementioned risk of falling.

[0037] Specifically, the outer sides of the aforementioned synchronous pulley 235 and synchronous belt 245 are also protected by a synchronous belt cover 275 provided on the side of the connecting seat 205. Of course, the synchronous belt cover 275 also has an avoidance groove on the side near the rotor 206 to avoid interference with the rotor 206.

[0038] Specifically, an outer cover 265 is fixed to the front side of the aforementioned connecting seat 205. The outer cover 265 and the chip baffle 255 together form a chamber to protect the cutter head motor 215 and the worm gear 225, so as to reduce the erosion caused by dust and debris, thereby extending the service life of the equipment.

[0039] Furthermore, a lead screw 101 driven to rotate by a lead screw motor 121 is longitudinally arranged in the middle of the above-mentioned upright frame 1. The lead screw 101 is driven to rotate by the lead screw motor 121 located at the top of the upright frame 1. The lifting seat 4 is slidably mounted on the front side of the upright frame 1 via a slider and a guide rail. A clamping ring 401 is integrally formed on its back, and the clamping ring 401 is engaged with a threaded block 111 on the lead screw 101. When the lead screw 101 rotates, the threaded block 111 can drive the lifting seat 4 to move up and down, and drive the tool magazine 2 to make corresponding swinging movements through the guide plate 402.

[0040] Furthermore, the 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-lobed claw structure. The main shaft 5 has a tool-clamping arm 502 that is hinged relative to the lifting seat 4, and the top seat 102 is fixed with a block 112 with an arc surface. The roller 512 at the end of the tool-clamping arm 502 can cooperate with the block 112 to control the main shaft 5 to clamp or release the designated tool 3. Of course, the tool-clamping arm 502 can also be elastically connected to the lifting seat 4 through a tool-clamping arm spring (not shown in the figure) to realize its own reset action (the tool-clamping arm 502 is existing technology, and its specific principle will not be described in detail in this article).

[0041] Furthermore, the fixed installation between the above components can be achieved using various types of screws as fasteners.

[0042] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
