[0027] Example 1

[0028] Please see Figures 1-7 As shown, this embodiment proposes a machining bench drill, including a bench drill main unit 1 and a protective cover 2 assembled below the bench drill main unit 1, and a docking box 5 assembled on the rear side of the protective cover 2. A drill chuck 103 is rotatably installed on the front side of the bottom of the bench drill main unit 1, and a drill bit 104 is fixedly installed inside the drill chuck 103. A feed handle 105 is rotatably installed on the front side of one side of the bench drill main unit 1. A support column 101 is fixedly installed on the rear side of the bottom of the bench drill main unit 1, and a base 102 is fixedly installed on the bottom of the support column 101. An mounting plate 6 is fixedly installed on the back of the protective cover 2, and the mounting plate 6 is fixedly installed on the outer wall of the support column 101. A liquid guide pipe 3 is fixedly connected to one side of the protective cover 2, and one end of the liquid guide pipe 3 extends into the interior of the protective cover 2 and is fixedly installed with a cooling nozzle 301.

[0029] In use, the support column 101 and base 102 support the bench drill main unit 1. The drive structure inside the bench drill main unit 1 drives the drill chuck 103 to rotate, and the drill chuck 103 can install and fix the drill bit 104. Thus, when the drill chuck 103 rotates, it can synchronously drive the drill bit 104 to rotate. The feed handle 105 is connected to the push mechanism inside the bench drill main unit 1. The operator can lower the drill chuck 103 and drill bit 104 by operating the feed handle 105, so that the drill bit 104 can perform drilling operations on the workpiece on the bench drill table. The back of the mounting plate 6 is fixedly installed on the outer wall of the support column 101, and the protective cover 2... The protective cover 2 is fixedly installed on the front of the mounting plate 6 and is fitted over the outside of the drill chuck 103 and drill bit 104. The protective cover 2 can shield and protect the drill chuck 103 and drill bit 104 when they rise and reset. The fluid guide pipe 3 is fixedly connected to one side of the protective cover 2 and is connected to the external cutting fluid delivery mechanism. The cutting fluid can be transmitted through the fluid guide pipe 3 and discharged through the cooling nozzle 301. The cooling nozzle 301 can spray the cutting fluid onto the surface of the drill bit 104, thereby realizing automatic cooling of the drill bit 104, increasing the functionality of the bench drill, reducing the workload of personnel, and improving the efficiency of bench drill operation.

[0030] Example 2

[0031] Based on Example 1, such as Figures 1-7 As shown, a rotary motor 207 is fixedly installed at the bottom of the back of the protective cover 2. A liquid collection box 201 that works with the protective cover 2 is fixedly installed at the output end of the rotary motor 207. A drain hole 202 is provided at the center of the liquid collection box 201. A closing plate 203 is movably installed above the drain hole 202. A protruding rod 204 extending to the bottom of the liquid collection box 201 is fixedly installed at the bottom of the closing plate 203. A fixing plate 602 is fixedly installed at the bottom of the mounting plate 6. A docking box 5 is fixedly installed at one end of the fixing plate 602. A shovel plate 501 that works with the protruding rod 204 is fixedly installed at the top of the docking box 5. A drain pipe 503 is fixedly connected to the bottom of the docking box 5.

[0032] In use, the rotary motor 207 is fixedly installed at the bottom of the back of the protective cover 2. A liquid collection box 201 is fixedly installed at the output end of the rotary motor 207. The rotary motor 207 is connected to the control mechanism inside the bench drill via a wire. When the drill chuck 103 and the drill bit 104 rise, the control mechanism of the bench drill sends a reverse command to the rotary motor 207, which moves the liquid collection box 201 to the bottom of the protective cover 2. The liquid collection box 201 can collect the cutting fluid dripping from the cooling nozzle 301 when spraying the drill bit 104, preventing excess cutting fluid from dripping directly. To prevent contamination of the workpiece surface on the bench drill table, this design enhances the functionality of the bench drill and improves the stability of the drill bit 104 during automatic cooling. When the drill chuck 103 and drill bit 104 descend, the control mechanism of the bench drill sends a forward rotation command to the rotary motor 207, which rotates the liquid collection box 201 to one side, thus preventing the drill chuck 103 and drill bit 104 from contacting the liquid collection box 201 during descent. A fixing plate 602 is fixedly installed on the bottom of the mounting plate 6, and a docking box 5 is fixedly installed on one end of the fixing plate 602. When the liquid collection box 201 passes through... When driven by the rotary motor 207, the fluid collection box 201 moves to the top of the docking box 5. A drain hole 202 is provided at the bottom of the drain hole 202, and a closing plate 203 is movably installed on the top of the drain hole 202. The closing plate 203 can close the drain hole 202, thus ensuring stable storage of cutting fluid in the collection box 201. A protruding rod 204 is fixedly installed at the bottom of the closing plate 203, and the bottom of the protruding rod 204 extends below the bottom of the collection box 201. Therefore, when the collection box 201 moves the top of the docking box 5, the fluid inside the docking box 5... The shovel plate 501 can lift the protruding rod 204, and the protruding rod 204 can simultaneously drive the closing plate 203 to lift. The lifting of the closing plate 203 can open the drain hole 202, thereby allowing the cutting fluid collected inside the collection box 201 to be discharged into the docking box 5. The bottom of the docking box 5 is fixedly connected to the drain pipe 503, which can conduct and discharge the cutting fluid recovered inside the docking box 5, realizing the function of automatic discharge of collected cutting fluid and avoiding the need for staff to manually clean it regularly.

[0033] like Figure 6 and Figure 7 As shown, a support plate 206 is fixedly installed on the upper part of the inner wall of the liquid collection box 201, and a support spring 205 is fixedly installed on the bottom of one end of the support plate 206.

[0034] In use, the support plate 206 can be used to install and fix the support spring 205. The bottom of the support spring 205 contacts the closing plate 203, so that the closing plate 203 can be elastically pressed down and closed by the support spring 205, which ensures the tightness of the closing plate 203 in closing the drain hole 202 and avoids leakage. It also facilitates the resetting and closing of the closing plate 203 after opening.

[0035] like Figures 1-5 As shown, one end of the liquid guide tube 3 is fixedly connected to the liquid inlet connector 302, and one end of the liquid outlet tube 503 is fixedly connected to the liquid outlet connector 504.

[0036] In use, the inlet connector 302 facilitates the connection of the fluid guide pipe 3 to the external cutting fluid supply mechanism, and the drain connector 504 facilitates the connection of the drain pipe 503 to the external recovery tank, thus improving the convenience of use.

[0037] like Figures 1-4 As shown, a support rod 4 is fixedly installed on one side of the top of the base 102, and multiple sets of fixing rings 401 are fixedly installed on the outer wall of the support rod 4.

[0038] In use, the support rod 4 is fixedly installed on one side of the top of the base 102. The fixing ring 401 installed on the outer wall of the support rod 4 is connected to the liquid guide pipe 3 and the liquid drain pipe 503. Thus, the liquid guide pipe 3 and the liquid drain pipe 503 can be supported and fixed through the support rod 4 and the fixing ring 401 to ensure the stability of the liquid guide pipe 3 and the liquid drain pipe 503 during operation.

[0039] like Figure 7 As shown, a slot 502 is provided on one side of the top of the docking box 5 to cooperate with the protruding rod 204.

[0040] In use, the slot 502 facilitates the passage of the protrusion 204 when the liquid collection box 201 moves to the top of the docking box 5, avoiding the situation where the bottom of the protrusion 204 cannot move to the top of the docking box 5 because it is lower than the bottom of the liquid collection box 201, thus ensuring the stability of the cutting fluid in the liquid collection box 201 when it is discharged into the docking box 5.

[0041] like Figures 1-4 As shown, a locking shaft 601 is installed on the external thread of the mounting plate 6.

[0042] In use, the front of the locking shaft 601 abuts against the outer wall of the support column 101, thereby locking the mounting plate 6 on the outer wall of the support column 101. Loosening the locking shaft 601 makes it easier for workers to adjust the height of the mounting plate 6 during operation, thus improving the convenience of adjusting the height of the mounting plate 6.

[0043] Working principle: When the drill chuck 103 rises and resets, the cooling nozzle 301 sprays cutting fluid onto the surface of the drill bit 104, achieving automatic cooling of the drill bit 104 after operation. The protective cover 2 protects the cooling nozzle 301 during operation, preventing cutting fluid from being sprayed onto the outside. When the drill chuck 103 and drill bit 104 descend, the rotary motor 207 rotates the lower collection box 201 and rotates it above the docking box 5, thus facilitating the descent of the drill chuck 103 and drill bit 104 to drill the workpiece on the bench drill table. When the collection box 201 is rotated above the docking box 5, the shovel plate 501 can be lifted by the protruding rod 204. When the protruding rod 204 is lifted, the closing plate 203 is lifted, thereby opening the drain hole 202, facilitating the drainage of the cutting fluid collected inside the collection box 201 into the interior of the docking box 5, and then discharged through the drain pipe 503.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
