Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to a drilling machine for mechanical parts. Background Technology

[0002] A drilling machine is a machine tool that primarily uses a drill bit to machine holes in a workpiece. Typically, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. Drilling machines have a simple structure and relatively low machining accuracy. They can drill through holes and blind holes. By changing special cutting tools, they can also perform reaming, countersinking, boring, or tapping operations.

[0003] Currently, when drilling machines are used to drill holes in mechanical parts, cutting fluid is usually added to effectively cool and lubricate the drill bit, reducing friction and wear between the drill bit and the workpiece. However, existing drilling machines for mechanical parts usually require manual addition of cutting fluid by the operator. Manual addition of cutting fluid may cause the operator to come into contact with harmful substances due to hand tremors or shaking, which may easily endanger the operator's health.

[0004] Therefore, this utility model proposes a drilling machine for mechanical parts to solve the above problems. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a drilling machine for mechanical parts, which effectively solves the problem that in existing technologies, when drilling machines are used to drill holes in mechanical parts, operators need to manually add cutting fluid. Manually adding cutting fluid may cause operators to come into contact with harmful substances due to hand tremors or shaking, thus posing a health hazard to the operators.

[0006] This utility model provides a drilling machine for mechanical parts, including a protective shell. An electric push rod is fixedly connected to the inner wall of the protective shell. A liquid collecting plate is fixedly connected to the output end of the electric push rod. A drilling assembly is fixedly connected to the lower end of the liquid collecting plate. A first conductive block is fixedly connected to the inner wall of the protective shell. A support rod is fixedly connected to the outer wall of the output end of the electric push rod. A second conductive block matching the first conductive block is fixedly connected to the outer wall of the support rod. A fixing mechanism is installed on the outer wall of the protective shell. A liquid collecting tank is fixedly connected to the upper end of the protective shell. Cutting fluid is placed inside the liquid collecting tank. A first liquid outlet pipe is connected to the lower end of the liquid collecting tank. A solenoid valve is installed on the outer wall of the first liquid outlet pipe. Two second liquid outlet pipes with corresponding positions are connected to the lower end of the liquid collecting plate. Liquid outlet heads are connected to the lower ends of the two second liquid outlet pipes.

[0007] Furthermore, the fixing mechanism includes a geared motor connected to the outer wall of the protective housing, a bidirectional threaded rod rotatably connected to the inner wall of the protective housing, one end of the bidirectional threaded rod being fixedly connected to the output end of the geared motor, and two corresponding sliders being threaded onto the rod wall of the bidirectional threaded rod, with a fixing plate fixedly connected to the upper end of each slider.

[0008] Furthermore, a placement plate is fixedly connected to the inner wall of the protective shell, and a pre-fixing groove is provided at the upper end of the placement plate.

[0009] Furthermore, both the first conductive block and the second conductive block are electrically connected to the solenoid valve.

[0010] Furthermore, the outer wall of the placement plate has an opening that matches the fixing plate.

[0011] Furthermore, the lower end of the protective shell is fixedly connected to a plurality of legs that correspond to each other in position, and the lower ends of the plurality of legs are fixedly connected to rubber anti-slip pads.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: When drilling mechanical parts, the drilling assembly enables automatic supply of cutting fluid during the drilling process through the automatic contact of the first and second conductive blocks and the cooperation of the solenoid valve. This prevents workers from directly contacting harmful substances and effectively avoids harm to their health. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example: Refer to Figures 1 to 3 A drilling machine for mechanical parts includes a protective housing 1. An electric push rod 2 is fixedly connected to the inner wall of the protective housing 1. A liquid collecting plate 3 is fixedly connected to the output end of the electric push rod 2. A drilling assembly 4 is fixedly connected to the lower end of the liquid collecting plate 3. A first conductive block 5 is fixedly connected to the inner wall of the protective housing 1. A support rod 6 is fixedly connected to the outer wall of the output end of the electric push rod 2. A second conductive block 7, matching the first conductive block 5, is fixedly connected to the outer wall of the support rod 6. A fixing mechanism 9 is installed on the outer wall of the protective housing 1. A liquid collecting tank 10 is fixedly connected to the upper end of the protective housing 1. The liquid collecting tank 10 contains cutting fluid. The lower end of the liquid collecting tank 10 is connected to a first outlet... The outer wall of the first liquid outlet pipe 11 is equipped with a solenoid valve 12 (the solenoid valve 12 is a normally closed solenoid valve, which is existing technology and will not be described in detail here). The lower end of the liquid collection plate 3 is connected to two corresponding second liquid outlet pipes 13. The lower ends of the two second liquid outlet pipes 13 are connected to liquid outlet heads 14, so that when the drilling assembly 4 drills the mechanical parts, it can realize the automatic supply of cutting fluid during the drilling process with the automatic contact of the first conductive block 5 and the second conductive block 7 and the cooperation of the solenoid valve 12. This can prevent workers from directly contacting harmful substances and effectively avoid harm to the health of workers.

[0019] The fixing mechanism 9 includes a geared motor 91 connected to the outer wall of the protective housing 1. A bidirectional threaded rod 92 is rotatably connected to the inner wall of the protective housing 1. One end of the bidirectional threaded rod 92 is fixedly connected to the output end of the geared motor 91. Two sliders 93 with corresponding positions are threaded onto the rod wall of the bidirectional threaded rod 92. A fixing plate 94 is fixedly connected to the upper end of each slider 93.

[0020] The inner wall of the protective shell 1 is fixedly connected to a placement plate 8. The upper end of the placement plate 8 is provided with a pre-fixing groove 15. The design of the pre-fixing groove 15 makes it easier for the placement plate 8 to be aligned and fixed with the fixing plate 94, reducing the complexity of operation and improving the convenience of use.

[0021] Both the first conductive block 5 and the second conductive block 7 are electrically connected to the solenoid valve 12.

[0022] The outer wall of the placement plate 8 has an opening that matches the fixing plate 94.

[0023] The lower end of the protective shell 1 is fixedly connected to multiple support legs 16 at corresponding positions, and the lower ends of the multiple support legs 16 are all fixedly connected to rubber anti-slip pads 17.

[0024] The operating principle of this utility model is described as follows: When in use, the staff first place the mechanical parts in the pre-fixed groove 15, and then start the reduction motor 91, so that the output end of the reduction motor 91 drives the bidirectional threaded rod 92 to rotate. At this time, the two sliders 93 will drive the fixing plate 94 to move relative to each other, so that the two fixing plates 94 can limit the mechanical parts. Then, the electric push rod 2 is activated, causing its output end to move the drilling assembly 4 downwards via the liquid collection plate 3. During this downward movement, the output end of the electric push rod 2 moves the first conductive block 5 downwards via the support rod 6 until the first conductive block 5 contacts the second conductive block 7. Since the solenoid valve 12 is electrically connected to the first conductive block 5 and the second conductive block 7, it is activated, allowing the cutting fluid in the liquid collection tank 10 to flow out through the first outlet pipe 11, the liquid collection plate 3, and the second outlet pipe 13. Finally, the fluid flows through the outlet head 14 to the drilling point. This ensures that the drilling assembly 4 can automatically supply cutting fluid during drilling by automatically contacting the first conductive block 5 and the second conductive block 7 and cooperating with the solenoid valve 12. This prevents workers from directly contacting harmful substances and effectively avoids harm to their health.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
