Description

Technical Field

[0001] The utility model relates to the field of drilling and tapping of die castings, in particular to a drilling and tapping dual-purpose machine for processing die castings. Background Art

[0002] Die castings are metal parts manufactured through the die-casting process. After the die castings are initially manufactured into blanks, operators need to drill and tap the blanks to facilitate the installation of screws and nuts, thereby installing the die castings. When using a drilling and tapping machine to process die castings, both drilling and tapping operations can be completed by simply replacing the drill bit and tap.

[0003] Currently, when drilling a die-casting with a drill, the die-casting is usually drilled directly to the desired position. However, since the waste chips generated by drilling are not cleaned in time, the friction between the waste chips and the drill bit will increase the wear of the drill bit and shorten the service life of the drill bit. If the drill bit is drilled at a high speed, the wear of the drill bit will be further aggravated. In addition, the accumulation of waste chips in the drilling area will interfere with the normal cutting of the drill bit, resulting in uneven drilling, inaccurate size or deterioration of surface quality. Therefore, in order to solve the above problems, a drilling and tapping machine for die-casting processing is proposed. Utility Model Content

[0004] In order to make up for the shortcomings of the prior art, which is the problem that waste chips are not cleaned in time, resulting in reduced drilling accuracy and reduced service life of the drill bit, the utility model provides a drilling and tapping machine for die casting processing.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a drilling and tapping machine for die casting processing, comprising a base, a hydraulic rod fixedly mounted on the top of the base, an output end of the top of the hydraulic rod fixedly connected to an operating table, a drill clamp rotatably connected to the bottom end of the front side of the operating table, a processing device clamped at the bottom end of the drill clamp, and a cleaning assembly provided on the surface of the hydraulic rod;

[0006] The cleaning assembly includes a connecting sleeve that is sleeved on the surface of the hydraulic rod, the front side of the connecting sleeve is fixedly connected to a connecting plate, the front end of the connecting plate is fixedly connected to a processing table, an airbag is provided at the top of the connecting plate, the left and right sides of the connecting plate are fixedly connected to straps, the interior of the airbag is fixedly connected to a reset spring, and the rear end of the airbag is fixedly connected to a one-way inflation valve.

[0007] Preferably, the processing table is located below the drill clamp, and a through hole compatible with the processing device is opened on the surface of the processing table. The drill clamp drives the processing device to move downward and drill and tap the die-casting.

[0008] Preferably, the strap is wrapped around and connected to the surface of the airbag, and the strap defines the position of the airbag. The upper and lower ends of the return spring are fixedly connected to the upper and lower ends of the inner wall of the airbag respectively.

[0009] Preferably, the one-way inflation valve allows gas to flow only from the outside to the inside of the airbag. When the external pressure disappears, the return spring releases energy to push the airbag back to its original position. At this time, external air is sucked into the inside of the airbag through the one-way inflation valve.

[0010] Preferably, the front end of the airbag is fixedly connected to an air guide tube, the front end of the air guide tube is fixedly connected to a hollow plate, the left and right sides of the front end of the hollow plate are fixedly connected to guide plates, exhaust holes are provided on the surface of the guide plate, the bottom end of the operating table is fixedly connected to a buffer spring, and the bottom end of the buffer spring is fixedly connected to a pressure plate.

[0011] Preferably, the rear end of the air guide tube is connected to the air bag, and the front end of the air guide tube is connected to the hollow plate. The bottom end of the hollow plate is attached to the rear side of the top of the processing table. The air inside the air bag is discharged to the hollow plate through the air guide tube, and then the air is sprayed from the exhaust hole inside the hollow plate to the die-casting on the top of the processing table, thereby removing the waste chips generated on the surface of the die-casting.

[0012] Preferably, the bottom end of the pressing plate is in contact with the top of the airbag, and when the pressing plate moves downward along with the operating table, the pressing plate presses the airbag and causes the air inside the airbag to be ejected.

[0013] The utility model is beneficial in that:

[0014] The utility model places the die-casting on the top of the processing table. When drilling or tapping the die-casting, the air bag is pressed and the air inside is sprayed toward the die-casting, so that the waste chips generated at the processing part of the die-casting are cleaned, thereby preventing the waste chips from accumulating and affecting the processing accuracy. In addition, after the waste chips are cleaned, they will not wear against the drill bit, thereby increasing the service life of the drill bit. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The following is combined with Figure 1-5 To further explain this application,

[0024] The embodiment of the present application discloses a drilling and tapping machine for die casting processing. Figure 1 A drilling and tapping machine for die casting processing includes a base 1, a hydraulic rod 2 is fixedly mounted on the top of the base 1, an output end of the top of the hydraulic rod 2 is fixedly connected to an operating table 31, a drill clamp 32 is rotatably connected to the bottom end of the front side of the operating table 31, and a processing device 33 is clamped at the bottom end of the drill clamp 32. The processing device 33 has two types of drill bits and taps. A cleaning component 4 is provided on the surface of the hydraulic rod 2;

[0025] Reference Figure 2-Figure 4The cleaning assembly 4 includes a connecting sleeve 41 that is sleeved on the surface of the hydraulic rod 2. The front side of the connecting sleeve 41 is fixedly connected to a connecting plate 42. The front end of the connecting plate 42 is fixedly connected to a processing table 43. The processing table 43 is located below the drill clamp 32. The surface of the processing table 43 is provided with a through hole that is compatible with the processing device 33. The drill clamp 32 drives the processing device 33 to move downward and drill and tap the die-casting. An air bag 44 is provided on the top of the connecting plate 42. The left and right sides of the connecting plate 42 are fixedly connected with a strap 45. The interior of the air bag 44 is fixed. A return spring 46 is fixedly connected, and a strap 45 is wrapped around and connected to the surface of the airbag 44. The strap 45 limits the position of the airbag 44. The upper and lower ends of the return spring 46 are fixedly connected to the upper and lower ends of the inner wall of the airbag 44 respectively. The rear end of the airbag 44 is fixedly connected to a one-way inflation valve 47. The one-way inflation valve 47 allows gas to flow only from the outside to the inside of the airbag 44. When the external pressure disappears, the return spring 46 releases energy and pushes the airbag 44 to return to its original position. At this time, external air is sucked into the inside of the airbag 44 through the one-way inflation valve 47.

[0026] Reference Figure 2-Figure 5 The front end of the air bag 44 is fixedly connected to an air guide tube 481, the front end of the air guide tube 481 is fixedly connected to a hollow plate 482, the left and right sides of the front end of the hollow plate 482 are fixedly connected to guide plates 483, the surface of the guide plate 483 is provided with exhaust holes 484, the rear end of the air guide tube 481 is connected to the air bag 44, the front end of the air guide tube 481 is connected to the hollow plate 482, the bottom end of the hollow plate 482 is attached to the rear side of the top of the processing table 43, and the air inside the air bag 44 is discharged to the hollow plate 482 through the air guide tube 481. Plate 482, and then the air is sprayed from the exhaust hole 484 inside the hollow plate 482 to the die-casting on the top of the processing table 43, thereby removing the waste chips generated on the surface of the die-casting. The bottom end of the operating table 31 is fixedly connected with a buffer spring 491, and the bottom end of the buffer spring 491 is fixedly connected with a pressure plate 492. The bottom end of the pressure plate 492 is in adaptive contact with the top of the airbag 44. When the pressure plate 492 moves downward with the operating table 31, the pressure plate 492 will press the airbag 44 and make the air inside the airbag 44 spray out.

[0027] Working principle: The operator places the die-casting on the top of the processing table 43, then installs the drill bit at the bottom of the drill clamp 32. At this time, the hydraulic rod 2 is driven to move the operating table 31 downward, and the motor inside the operating table 31 is driven to rotate the drill clamp 32 and the processing device 33 to drill the die-casting. After drilling is completed, the hydraulic rod 2 is first driven to move the processing device 33 away from the die-casting. Then, the drill bit is removed and the tap is installed. At this time, the equipment is operated again to tap the die-casting with the tap.

[0028] During the process of the operating table 31 moving downward in a cycle and driving the processing device 33 to operate on the die-casting, the operating table 31 will drive the buffer spring 491 and the pressure plate 492 to move downward. At this time, the pressure plate 492 will press down the airbag 44, causing the airbag 44 to be compressed. At this time, the airbag 44 will compress the internal return spring 46 and discharge the internal gas through the air guide pipe 481. The discharged gas will be sprayed into the interior of the hollow plate 482 through the air guide pipe 481, and then flow to the left and right sides of the hollow plate 482 under the guidance of the guide plate 483 inside the hollow plate 482, and will be ejected forward through the exhaust hole 484 during the gas flow. The gas ejected forward will be sprayed toward the die-casting. At this time, the flowing gas will blow the die-casting being processed, so that the waste chips generated by drilling and tapping on the surface of the die-casting are blown away from the die-casting, thereby facilitating subsequent drilling and tapping.

[0029] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
