Description

Technical Field

[0001] This utility model belongs to the field of machining technology, specifically relating to a drilling device for machining. Background Technology

[0002] In the machining system, drilling is a crucial fundamental process that runs through the entire process from basic parts manufacturing to precision equipment assembly. Hole structure is a core feature of parts such as housings and brackets. Drilling achieves hole formation by rotating a drill bit to cut the material, providing the foundation for component connections (such as bolt holes) and functional structures (such as oil passage holes).

[0003] Drilling equipment uses a motor or other motor to drive the drill bit to rotate at high speed (main motion) and feed axially. It removes material using cutting edges and uses spiral grooves for chip removal and coolant for cooling. Although it is a roughing process (with an accuracy of around IT10-IT13), it is a prerequisite for subsequent finishing processes such as reaming and boring. Its high efficiency and adaptability to various materials (steel, aluminum, etc.) make mass production possible and significantly improve manufacturing efficiency.

[0004] Existing drilling equipment often requires users to manually adjust the clamping mechanisms on both sides to fix the position of mechanical parts during processing. Manual clamping can lead to differences in processing accuracy due to experience and conditions, resulting in scrap and rework due to hole position deviation. In addition, manual clamping is inefficient and can easily affect the efficiency of drilling processing. Utility Model Content

[0005] The purpose of this utility model is to provide a drilling device for machining, which aims to solve the problem that existing drilling equipment often requires users to manually adjust the clamping mechanisms on both sides to fix the position when machining mechanical parts. Manual clamping is prone to differences in machining accuracy due to experience and condition, which leads to scrap and rework due to hole position deviation. In addition, manual clamping is inefficient and easily affects the efficiency of drilling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for machining, comprising a drilling machine body, a drill bit assembly mounted on the top of the drilling machine body, a cabinet door rotatably connected to the lower end of the drilling machine body via a hinge, a mounting frame connected to the top surface of the drilling machine body, a motor mounted on one side surface of the mounting frame, a bidirectional lead screw connected to the output end surface of the motor, the other side of the bidirectional lead screw being sleeved in a bearing connected to the surface of the mounting frame, a moving rod slidably connected to the surface of the mounting frame, one end of the moving rod being threadedly connected to the bidirectional lead screw, a slot being formed on the surface of the other end of the moving rod, a connecting frame being inserted into the slot, the moving rod being threadedly connected to the surface of the connecting frame via bolts, a clamping frame connected to the other side surface of the connecting frame, the bottom of the clamping frame abutting against the surface of the drilling machine body's operating table, a chip groove being formed on the surface of the drilling machine body's operating table, a scrap box abutting against the bottom surface of the drilling machine body's operating table, and sliding grooves being formed on both sides of the scrap box.

[0007] As a preferred embodiment of the drilling device for machining according to this utility model, the mounting frame has two sets of rectangular through slots opened laterally on its surface, and the shape and size of the through slots are adapted to the moving rod.

[0008] As a preferred embodiment of the drilling device for machining according to this utility model, the clamping frame has a "V" shaped structure, and rubber strips are bonded to its inner wall surface at equal intervals.

[0009] As a preferred embodiment of the drilling device for machining according to this utility model, the surface of the slide is movably inserted into the surface of the side block, the other side surface of the side block is connected to the inner wall of the lower end of the drilling machine body, and one side surface of the waste box abuts against the cabinet door.

[0010] As a preferred embodiment of the drilling device for machining according to this utility model, the side block is a "T"-shaped integrated structure, the shape and size of which are adapted to the slide groove, and the side block is made of rubber.

[0011] As a preferred embodiment of the drilling device for machining according to this utility model, the moving rod, slot, connecting frame, bolt and clamping frame form a threaded connection structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By cooperating with the mounting bracket, motor, double-acting lead screw, moving rod, slot, connecting bracket, bolt, and clamping bracket, the mechanical parts to be processed are placed on the operating table of the drilling machine body. Then, the motor drives the two clamping brackets on the connected double-acting lead screw to clamp and fix the mechanical parts, thereby facilitating the drill bit assembly to perform precise drilling on the surface of the parts and improving the efficiency and quality of drilling.

[0014] By utilizing the interplay between the chip trough, waste box, chute, and side blocks, the chips generated during processing fall through the chip trough into the waste box below for collection. This prevents waste from accumulating on the drilling machine's operating table, facilitates centralized chip collection, and eliminates the need for frequent manual cleaning of the operating table surface. Post-processing cleaning simply requires removing the chip box and emptying the chips, saving labor and time costs. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-5This utility model provides the following technical solution: a drilling device for machining, including a drilling machine body 1, a drill bit assembly 2 mounted on the top of the drilling machine body 1, a cabinet door 3 rotatably connected to the lower end of the drilling machine body 1 via a hinge, a mounting frame 4 connected to the top surface of the drilling machine body 1, a motor 5 mounted on one side surface of the mounting frame 4, a bidirectional lead screw 6 connected to the output end surface of the motor 5, the other side of the bidirectional lead screw 6 being sleeved in a bearing connected to the surface of the mounting frame 4, a moving rod 7 slidably connected to the surface of the mounting frame 4, one end of the moving rod 7 being threadedly connected to the bidirectional lead screw 6, a slot 8 being formed on the surface of the other end of the moving rod 7, a connecting frame 9 being inserted into the surface of the slot 8, and the connecting frame 9... The moving rod 7 is connected to the surface by bolt 10. The other side of the connecting frame 9 is connected to the clamping frame 11. The bottom of the clamping frame 11 abuts against the surface of the operating table of the drilling machine body 1. The surface of the operating table of the drilling machine body 1 is provided with a chip groove 12. The bottom surface of the operating table of the drilling machine body 1 abuts against the waste box 13. The two sides of the waste box 13 are provided with sliding grooves 14. In this design, the drilling machine body 1, the drill bit assembly 2 and the cabinet door 3 constitute the main body of the hydraulic drilling machine. A large number of related components are set in the main body of the hydraulic drilling machine. Since they are existing technologies and the core content of this technical solution is not related to them, they will not be described in detail in this technical solution.

[0024] The main model of the hydraulic drilling machine in this solution is: D8513 hydraulic drilling machine.

[0025] In use: When the main body of the hydraulic drilling machine is working, the motor drives the spindle to rotate via belt, pulley, and spline pair. At the same time, the hydraulic station provides the prime mover. Through the oil cylinder mechanism and speed control valve inside the spindle, the conversion between fast feed and working feed is realized. The working feed speed is changed by adjusting the speed control valve knob. The upper and lower limit travel switches are used to control the spindle reset position and drilling depth, respectively, so as to perform drilling processing on the mechanical parts held by the clamping frame 11 on the operating table on the surface of the drilling machine body 1.

[0026] Preferably, two sets of rectangular through slots are opened horizontally on the surface of the mounting bracket 4, and the shape and size of the through slots are adapted to the moving rod 7.

[0027] In practical use, when the motor 5 starts, its output end drives the connected bidirectional lead screw 6 to rotate in the sleeved bearing, thereby causing the two moving rods 7 threaded on the bidirectional lead screw 6 to move towards the middle at the same time. The moving rods 7 move in the through slot opened on the mounting bracket 4, thereby limiting the range of movement of the moving rods 7.

[0028] Preferably, the clamping frame 11 has a "V" shaped structure, and rubber strips are bonded to its inner wall surface at equal intervals.

[0029] In practical use, the rubber strips on the inner wall of the clamping frame 11 abut against both sides of the surface of the mechanical parts, thereby increasing the friction between the two and making the clamped mechanical parts more stable.

[0030] Preferably, the surface of the slide 14 is movably inserted into the surface of the side block 15, the other side surface of the side block 15 is connected to the lower inner wall of the drilling machine body 1, and one side surface of the waste box 13 abuts against the cabinet door 3.

[0031] In practical use, hold the handle at the bottom of the waste box 13 and pull the waste box 13 outward, so that the sliding grooves 14 on both sides of it disengage from the sleeved side blocks 15, and then take out the waste box 13 to uniformly process the debris collected inside.

[0032] Preferably, the side block 15 is a "T"-shaped integrated structure, the shape and size of which are adapted to the groove 14, and the side block 15 is made of rubber.

[0033] In practical use, after cleaning the debris inside the waste box 13, the above operation is repeated so that the rubber side block 15 can increase the friction between it and the waste box 13, thereby fixing the connection of the waste box 13 on the side block 15.

[0034] Preferably, the moving rod 7, slot 8, connecting frame 9, bolt 10 and clamping frame 11 form a threaded connection structure.

[0035] In practical use, select the appropriate clamping frame 11 according to the size of the mechanical parts to be drilled, and then insert the connecting frame 9 connected on one side of the two clamping frames 11 into the slot 8 respectively. Then, use bolts 10 to thread the moving rod 7 and the connecting frame 9 that are inserted together, thereby fixing the position of the two clamping frames 11 on one side of the mounting frame 4.

[0036] Working principle: When drilling is required on a mechanical part, select the appropriate clamping frame 11 according to the size of the mechanical part to be drilled. Then, insert the connecting frame 9 connected to one side of the two clamping frames 11 into the slot 8 respectively. Then, use bolts 10 to thread the inserted moving rod 7 and the connecting frame 9 together, thereby fixing the position of the two clamping frames 11 on one side of the mounting frame 4. Then, place the mechanical part to be processed on the operating table on the top of the drilling machine body 1, and start the motor 5. When the motor 5 starts, its output end drives the connected double-acting screw 6 to rotate in the sleeved bearing, thereby causing the two moving rods 7 threaded on the double-acting screw 6 to move towards the middle at the same time, until the two sides of the clamping frame 11 abut against the two sides of the mechanical part respectively. Then, the motor 5 stops running and... The internal electromagnetic brake locks the connected bidirectional lead screw 6, thereby fixing the two clamping frames 11 to hold the mechanical parts. Then, the drill assembly 2 drills the mechanical parts placed at its bottom. The debris generated during drilling falls directly into the waste box 13 through the debris groove 12 below, preventing debris from accumulating on the operating table at the top of the drilling machine body 1. After processing is completed, the cabinet door 3 can be opened by rotating the hinge connecting the drilling machine body 1 and the cabinet door 3. Then, the handle at the bottom of the waste box 13 can be grasped and pulled outward to disengage the sliding grooves 14 on both sides from the sleeved side blocks 15. The waste box 13 can then be taken out and the debris collected inside can be processed uniformly so that the debris generated during subsequent processing can continue to be collected.

[0037] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
