Description

Technical Field

[0001] This utility model belongs to the field of fully automatic screw drill technology, specifically a fully automatic screw drill with a positioning structure. Background Technology

[0002] A printing press is a machine for printing text and images. Modern printing presses generally consist of mechanisms for plate mounting, inking, printing, and paper feeding. The working principle is as follows: First, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Ink is then applied manually or by the printing press to the areas with text and images on the printing plate, and the ink is directly or indirectly transferred to paper or other substrates, thus reproducing a printed product identical to the printing plate. In the printing press production process, screw drills are important tools used for machining printing press parts.

[0003] Existing screw drills for printing press processing can drill holes in printing press parts by rotating the drill bit and applying pressure to the parts. However, they cannot effectively control the drilling depth and cannot meet the different drilling depth requirements of printing press parts. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic screw drill with a positioning structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fully automatic screw drill with a positioning structure is provided, including a processing table. A waste bin is movably connected to the lower part of the processing table. A fixed frame is fixedly connected to the top of the processing table. A drill is fixedly connected to the lower part of the fixed frame. The drill includes a motor fixedly connected to the lower part of the fixed frame. A fixed plate is fixedly connected to the lower part of the motor. A sliding column is fixedly connected to the lower part of the fixed plate. A fixed sleeve is fixedly connected to the lower part of the sliding column. A pressure cylinder is fixedly connected to the lower part of the fixed sleeve. A rotating shaft is fixedly connected to the output end of the motor. A screw is movably connected to the outer side of the rotating shaft. A lifting plate is movably connected to the outer side of the sliding column. The lifting plate includes a disc body movably connected to the outer side of the sliding column. A column hole is provided inside the disc body. A pressure shell is fixedly connected to the lower part of the disc body. A lifting block is movably connected to the inner side of the disc body. A lifting hole is provided inside the lifting block. Bolts are threadedly connected to both sides of the lifting block.

[0006] Optionally, the processing table includes a table body, with waste holes on both sides of the table body and a through hole in the middle of the table body, and a support column fixedly connected to the lower part of the table body.

[0007] Optionally, the waste bin includes a box body movably connected to the lower part of the platform, and a handle is fixedly connected to the front side of the box body.

[0008] Optionally, the fixing frame includes a fixing column fixedly connected to the top of the platform, a top plate fixedly connected to the top of the fixing column, a hydraulic telescopic rod fixedly connected inside the top plate, and a fixing plate fixedly connected to the lower end of the hydraulic telescopic rod.

[0009] Optionally, the fixed sleeve includes a sleeve body fixedly connected to the lower part of the sliding column, a rotating sleeve movably connected to the inner side of the sleeve body, a pressure column movably connected to the upper part of the rotating sleeve, an insert block movably connected to the inside of the rotating sleeve, an inclined groove provided on the top of the insert block, a screw hole provided in the middle of the inside of the rotating sleeve, and a spring fixedly connected between the rotating sleeve and the insert block.

[0010] Optionally, the screw includes a rod body movably connected to the outside of the rotating shaft, the rod body having a shaft groove inside, and lifting grooves on both sides of the outside of the rod body, with a drill bit fixedly connected to the lower end of the rod body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, by setting up a drilling tool, facilitates the positioning of the drill bit, allowing for adjustment of the drilling depth. During use, the screw is raised to its highest position, at which point the lower end of the drill bit and the lower end of the pressure cylinder are on the same horizontal plane. The position of the lifting plate is adjusted according to the required drilling depth. Loosening the bolts allows the lifting block to rise and fall outside the screw, thereby adjusting the overall height of the lifting plate. This adjustment ensures the distance between the pressure shell and the rotating sleeve matches the drilling depth. Tightening the bolts then secures the lifting plate against the screw. The workpiece is then placed on the processing table, aligning the drilling position with the through hole. Starting the motor causes the rotating shaft to drive the screw to rotate. The thread on the outer side of the screw matches the threaded hole. The rotation of the screw, both forward and reverse, allows for... The screw can move up and down inside the lifting block and outside the rotating shaft. When the screw rotates, it drives the lifting block to rotate inside the disc. When the screw moves up and down, it drives the lifting disc to move up and down. As the screw descends, the lifting disc descends, and the drill bit descends. Through continuous descent, the lifting disc can be inserted into the fixed sleeve, preventing the screw from moving further down. At the same time, the pressure shell can squeeze the pressure column, which forces the insert block to move into the rotating sleeve and detach from the sleeve. At this time, driven by the screw, the rotating sleeve can rotate inside the sleeve, allowing the screw to rotate smoothly after it stops moving up and down. The distance the lifting disc descends is equal to the distance the drill bit extends out of the pressure cylinder. The drilling depth can be controlled by adjusting the position of the lifting disc.

[0024] Reference Figures 1 to 5The present invention will now be described. A fully automatic screw drill with a positioning structure includes a processing table 1. A waste bin 2 is movably connected to the lower part of the processing table 1. A fixed frame 4 is fixedly connected to the top of the processing table 1. A drill 3 is fixedly connected to the lower part of the fixed frame 4. The drill 3 includes a motor 308 fixedly connected to the lower part of the fixed frame 4. A fixed plate 307 is fixedly connected to the lower part of the motor 308. A sliding column 304 is fixedly connected to the lower part of the fixed plate 307. The sliding column 304 is used to ensure greater stability when the lifting plate 305 is raised and lowered, and to allow the plate 305 to rotate. A fixed sleeve 302 is fixedly connected to the lower part of the sliding column 304. A pressure cylinder 301 is fixedly connected to the lower part of the fixed sleeve 302. The pressure cylinder 301 is used to contact the printing machine components. A rotating shaft 3 is fixedly connected to the output end of the motor 308. 06. A limiting groove is provided on the outer side of the rotating shaft 306, which is adapted to the shaft groove 3032, so that the rotating shaft 306 can drive the screw 303 to rotate, and the screw 303 can move up and down on the outer side of the rotating shaft 306. The screw 303 is movably connected to the outer side of the rotating shaft 306, and a lifting plate 305 is movably connected to the outer side of the sliding column 304. The lifting plate 305 includes a plate body 3055 movably connected to the outer side of the sliding column 304. The plate body 3055 has a column hole 3054 inside, which is used for the plate body 3055 to move up and down on the outer side of the sliding column 304. A pressure shell 3056 is fixedly connected to the lower part of the plate body 3055. The height of the pressure shell 3056 is equal to the distance from the top of the sleeve 3021 to the top of the rotating sleeve 3022, ensuring that the pressure shell 3056 can move up and down. The pressure column 3023 is pressed into the fixed sleeve 302. A lifting block 3051 is movably connected to the inner side of the disc 3055. The lifting block 3051 has a lifting hole 3052 inside, used for lifting and lowering the screw 303 from the outside. Bolts 3053 are threaded onto both sides of the lifting block 3051. During use, the screw 303 is raised to its highest position, at which point the lower end of the drill bit 3034 and the lower end of the pressure cylinder 301 are at the same horizontal plane. The position of the lifting disc 305 is adjusted according to the required drilling depth. Loosening the bolts 3053 allows the lifting block 3051 to rise and fall from the outside of the screw 303. This lifting and lowering allows for adjustment of the overall height of the lifting disc 305. This adjustment allows for the pressing... The distance between the housing 3056 and the rotating sleeve 3022 is the same as the drilling depth. Then, by tightening the bolt 3053, the lifting plate 305 is fixed to the screw 303. The workpiece is then placed on the processing table 1, with the drilling position corresponding to the through hole 104. The motor 308 is started, causing the rotating shaft 306 to drive the screw 303 to rotate. The screw 303 is threadedly connected to the sleeve 3021. The screw 303 can move up and down inside the lifting block 3051 and outside the rotating shaft 306 by rotating forward and backward. When the screw 303 rotates, it drives the lifting block 3051 to rotate inside the plate 3055. Furthermore, when the screw 303 moves up and down, it drives the lifting plate 305 to move up and down. When the screw 303 descends...The lifting plate 305 descends, simultaneously lowering the drill bit 3. Through continuous descent, the lifting plate 305 inserts into the fixed sleeve 302, preventing the screw 303 from moving further downwards. Simultaneously, the pressure shell 3056 presses against the pressure column 3023, causing the insert block 3024 to move into the rotating sleeve 3022, thus detaching it from the sleeve 3021. At this point, driven by the screw 303, the rotating sleeve 3022 rotates inside the sleeve 3021, allowing the screw 303 to rotate smoothly after the lifting stops. The distance the lifting plate 305 descends is equal to the distance the drill bit 3034 extends out of the pressure cylinder 301. Adjusting the position of the lifting plate 305 controls the drilling depth of the drill bit 3034.

[0025] Furthermore, the processing table 1 includes a table body 101. Both sides of the table body 101 are provided with waste holes 103. The waste holes 103 are used for the passage of waste generated during drilling, so that the waste can enter the waste box 2. The table body 101 has a through hole 104 in the middle, which is used for the passage of the drill bit 3034. The lower part of the table body 101 is fixedly connected to a support column 102, which is used to support the table body 101.

[0026] Furthermore, the waste bin 2 includes a box 201 movably connected to the lower part of the platform 101. The box 201 is used to collect the debris generated by drilling. A handle 202 is fixedly connected to the front side of the box 201. The box 201 can move under the platform 101, which facilitates the loading and unloading of the box 201 and thus facilitates the centralized processing of the waste collected in the waste bin 2.

[0027] Furthermore, the fixing frame 4 includes a fixing column 402 fixedly connected to the top of the platform 101. A top plate 401 is fixedly connected to the top of the fixing column 402. A hydraulic telescopic rod 403 is fixedly connected inside the top plate 401. A fixing plate 404 is fixedly connected to the lower end of the hydraulic telescopic rod 403. By controlling the hydraulic telescopic rod 403, the fixing plate 404 can be driven to descend, thereby allowing the drill 3 to descend, and the drill bit 3034 to descend and contact the workpiece. As the drill bit 3034 rotates, it drills a hole in the workpiece. As the drill bit 3034 continuously drills in, the pressure cylinder 301 continuously descends. When the pressure cylinder 301 contacts the workpiece, the drilling is completed.

[0028] Furthermore, the fixed sleeve 302 includes a sleeve body 3021 fixedly connected to the lower part of the sliding column 304. The inner side of the sleeve body 3021 has a slot for inserting the insertion block 3024. A rotating sleeve 3022 is movably connected to the inner side of the sleeve body 3021. A pressure column 3023 is movably connected to the upper part of the rotating sleeve 3022. The insertion block 3024 is movably connected inside the rotating sleeve 3022. The top of the insertion block 3024 has a slanted groove 3025, which is slanted. By pressing the pressure column 3023 downwards, the insertion block 3024 can retract into the rotating sleeve 3022, allowing the rotating sleeve 3022 to rotate inside the sleeve body 3021. A screw hole 3026 is provided in the middle of the interior of the rotating sleeve 3022. A spring 30 is fixedly connected between the rotating sleeve 3022 and the insertion block 3024. 27. When the drilling depth needs to be readjusted, loosen the bolt 3053 to allow the lifting plate 305 to move away from the fixed sleeve 302, so that the pressure shell 3056 releases the pressure on the pressure column 3023. By rotating the screw 303 in the opposite direction, the friction force causes the screw 303 to drive the rotating sleeve 3022 to rotate. The rotation causes the insertion block 3024 to correspond to the groove on the inner side of the sleeve 3021, and under the action of the spring 3027, the insertion block 3024 can be inserted into the groove on the inner side of the sleeve 3021, thereby fixing the rotating sleeve 3022. Then, the reverse rotation causes the screw 303 to move upward to the top so that the lower end of the drill bit 3034 is on the same horizontal plane as the lower part of the pressure cylinder 301. At this time, the position of the lifting plate 305 can be readjusted.

[0029] Furthermore, the screw 303 includes a rod 3031 movably connected to the outside of the rotating shaft 306. The rod 3031 has a shaft groove 3032 inside, which is used for the insertion of the rotating shaft 306, so that the rotating shaft 306 can drive the screw 303 to rotate and the screw 303 can be raised and lowered outside the rotating shaft 306. Both sides of the outer side of the rod 3031 are provided with lifting grooves 3033. The lower end of the rod 3031 is fixedly connected to a drill bit 3034. The lifting grooves 3033 are used to prevent the lifting block 3051 from rotating relative to the screw 303.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
