Description

Technical Field

[0001] This utility model relates to the field of parts tapping technology, specifically a tapping device for high-precision parts processing. Background Technology

[0002] High-precision components refer to parts or assemblies manufactured according to extremely strict tolerance requirements and high-quality standards during the manufacturing process. A tapping device is a tool system specifically used to machine internal threads on a workpiece. By using a tap to cut in a pre-drilled hole in the part, a precise thread shape can be created so that it can be mated with other parts with external threads to achieve the purpose of fastening or assembly.

[0003] During the tapping process, the friction between the tap and the workpiece material generates a lot of heat. High temperature will cause the tap material to soften and accelerate wear. Therefore, coolant is needed to control the tap temperature and extend its service life. Cooling usually requires the operator to manually pour or spray coolant onto the tapping area as needed, which is inefficient. Utility Model Content

[0023] Combination Figures 1-2 A high-precision parts machining tapping device includes a machining base 1, a side plate 2 fixedly connected to one side of the machining base 1, a top plate 3 fixedly connected to one side of the side plate 2, a first electric push rod 4 disposed at the bottom end of the top plate 3, a mounting base 41 fixedly connected to the telescopic end of the first electric push rod 4, a first motor 5 disposed inside the mounting base 41, and a tap 51 disposed at the output end of the first motor 5. A support plate 21 is fixedly connected to the side of the side plate 2 away from the top plate 3, and a cooling assembly 6 for cooling the tap 51 is disposed at the top of the support plate 21.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example 1:

[0026] Please see Figures 1-6 The cooling assembly 6 includes a water tank 61 fixedly installed on the top of the support plate 21, a water pump 62 located at the top of the water tank 61, a suction pipe 63 fixedly connected between the water tank 61 and the water pump 62, a water outlet hose 64 fixedly connected to the output end of the water pump 62, a connecting box 65 located at one end of the water outlet hose 64, a connecting pipe 66 located inside the connecting box 65, a connecting plate 69 fixedly connected to the bottom of the connecting box 65, a drain pipe 67 located below the connecting plate 69, and a nozzle 68 fixedly connected to one end of the drain pipe 67. One end of the connecting pipe 66 passes through the connecting box 65 and the water outlet hose 64. The water hose 64 is fixedly connected, and the other end of the connecting pipe 66 passes through the connecting slot box 65 and the connecting plate 69, and is rotatably connected to the drain pipe 67. The drain pipe 67 faces the tap 51. The water tank 61 is filled with coolant. Under the action of the water pump 62, the coolant enters the drain pipe 67 through the water outlet hose 64 and the connecting pipe 66 in sequence, and is finally sprayed out through the nozzle 68. The drain pipe 67 faces the tap 51 directly, ensuring that the coolant is sprayed directly onto the high-temperature area where the tap 51 contacts the part. This is efficient and convenient, effectively removes heat, reduces thermal damage and deformation of the tap 51, and helps control the temperature of the part.

[0027] The bottom of the connecting plate 69 is provided with a dust blowing assembly 8 for blowing away dust. The dust blowing assembly 8 includes a vertical plate 81 fixedly connected to the bottom of the connecting plate 69, a connecting block 82 fixedly connected to one side of the vertical plate 81, a motor 83 fixedly installed on one side of the connecting block 82, a drive wheel 84 fixedly connected to the output end of the motor 83, a driven wheel 85 meshing with one side of the drive wheel 84, a mounting plate 86 fixedly connected to the outer surface of the drain pipe 67, and a fan blade 87 fixedly connected to the outer surface of the mounting plate 86. The driven wheel 85 is fixedly connected to the outer surface of the drain pipe 67. The motor 83 drives the drive wheel 84 to rotate, which drives the driven wheel 85 to rotate, which in turn drives the drain pipe 67 to rotate, thereby driving the mounting plate 86 and the fan blade 87 to rotate. The rotation of the fan blade 87 facilitates the generation of a directional airflow that blows towards the tap 51, which not only improves the cooling effect but also facilitates the timely removal of debris, preventing debris from clogging during the tapping process and affecting the tapping effect.

[0028] A groove 22 is provided on one side of the side plate 2. A threaded rod 222 is provided inside the groove 22. A second motor 221 is fixedly installed at the bottom of the inner wall of the groove 22. One end of the threaded rod 222 is fixedly connected to the output end of the second motor 221, and the other end of the threaded rod 222 is rotatably connected to the inner wall of the groove 22. A slider 651 is threadedly connected to the outer surface of the threaded rod 222. The connecting slot box 65 is fixedly connected to the slider 651. The second motor 221 drives the threaded rod 222 to rotate. The rotation of the threaded rod 222 drives the slider 651 to move. The movement of the slider 651 drives the connecting slot box 65 to move, thereby driving the cooling component 6 and the chip blowing component 8 to move up and down, so as to adjust the height of the cooling component 6 and the chip blowing component 8 according to the position of the tap 51.

[0029] The top of the machining base 1 is provided with a fixing assembly 7 for fixing parts. The fixing assembly 7 includes a support block 71 fixedly connected to the top of the machining base 1, a second electric push rod 72 fixedly connected to one side of the support block 71, a clamping plate 73 fixedly connected to the telescopic end of the second electric push rod 72, a spring 74 fixedly connected to one side of the clamping plate 73, and a clamping pad 75 fixedly connected to one end of the spring 74. The clamping plate 73 is moved by the telescopic movement of the second electric push rod 72 to facilitate fixing the parts. The spring 74 provides elastic force for clamping, so that the clamping pad 75 can automatically adapt to the surface of the parts by the compression or extension of the spring 74 to provide appropriate clamping force.

[0030] The processing base 1 has a filter hole 11 at the top and a cavity 12 inside. The inner wall of the processing base 1 has a slide groove 13, and a collection tray 9 is slidably connected inside the slide groove 13. The filter hole 11, the cavity 12 and the slide groove 13 are all connected. The debris falling to the top of the processing base 1 can easily fall into the collection tray 9 through the filter hole 11. When the collection tray 9 is full or needs to be cleaned, it can be removed from the slide groove 13 for emptying or replacement simply by gently pulling the collection tray 9.

[0031] A filter plate 91 is fixedly connected inside the collection tray 9. The outer surface of the filter plate 91 has filter holes 911. The filter holes 911 on the filter plate 91 facilitate the passage of coolant while blocking larger solid particles, thus achieving effective separation of liquid and solid.

[0032] In use, the workpiece to be processed is placed on the top of the processing base 1. The second electric push rod 72 and spring 74 are used to fix the workpiece. The tap 51 is used to facilitate tapping. Under the action of the water pump 62, the coolant enters the drain pipe 67 through the outlet hose 64 and the connecting pipe 66 in sequence, and finally sprays out through the nozzle 68. The drain pipe 67 is directly facing the tap 51, ensuring that the coolant is directly sprayed onto the high-temperature area where the tap 51 contacts the workpiece. This is efficient, convenient, and facilitates the effective removal of heat. The motor 83 drives the drive wheel 84 to rotate, which in turn drives the driven wheel 85 to rotate. The driven wheel 85 rotates, which in turn drives the drain pipe 67 to rotate, thereby driving the mounting plate 86 and the fan blade 87 to rotate. This facilitates the generation of a directional airflow that blows towards the tap 51, which not only improves the cooling effect but also facilitates the timely removal of debris, preventing debris blockage during the tapping process. The debris falling to the top of the processing base 1 can easily fall into the collection tray 9 through the filter hole 11. Under the action of the filter plate 91, the coolant and debris particles are easily separated.
