Description

Technical Field

[0001] This utility model relates to the technical field of screw hole processing equipment, specifically to a tapping machine for processing screw holes in aluminum parts. Background Technology

[0002] An electric tapping machine is a machine tool that can tap the internal threads of various small and large aluminum parts, including coarse, fine, and non-standard pitch fastening connection threads, transmission connection threads, and pipe threads, in both forward and reverse rotation. This type of machine tool belongs to the category of flexible tapping and its significant feature is that it can be operated with a folding arm, making it suitable for tapping threads below M42.

[0003] However, when an electric tapping machine is performing tapping operations, the chips tend to fly everywhere, which is troublesome to clean up. Furthermore, the flying chips can easily splash onto the operator's body or even into their eyes, posing a certain safety hazard. Utility Model Content

[0004] To solve the above-mentioned technical problems, a tapping machine for machining screw holes in aluminum parts is provided. This solves the problem that in the prior art, electric tapping machines tend to scatter chips everywhere during tapping operations, which is troublesome to clean up and can easily splash chips onto the operator's body or even into their eyes, posing a certain safety hazard.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a tapping machine for machining screw holes in aluminum parts, including a base, a bracket fixed in an inverted L shape on the side of the top surface of the base, and a cylinder installed on the inner wall of the top of the bracket. A motor is installed on the telescopic end of the cylinder, and a drill bit is fixed on the output end of the motor. It also includes a protective mechanism to prevent debris from splashing and interfering with the machining process.

[0006] The protective mechanism includes a telescopic cover sleeve covering the outside of the motor and an annular connecting plate fastened to the cylinder telescopic rod. The telescopic cover sleeve is composed of a fixed sleeve detachably disposed on the bottom surface of the annular connecting plate and a movable sleeve slidably disposed on the outer wall of the fixed sleeve. The lowest end of the movable sleeve is located below the bottom end of the drill bit. A vacuum cleaner is installed on the top surface of the base, and a vacuuming component that cooperates with the vacuum cleaner is provided on the movable sleeve.

[0007] Preferably, the inner wall of the movable sleeve is provided with a plurality of movable grooves, and elastic elements are provided in the movable grooves.

[0008] Preferably, the elastic element includes a slider slidably disposed inside the movable groove, and a compression spring is fixed between the slider and the inner wall of the bottom end of the movable groove.

[0009] Preferably, the vacuuming assembly includes a vacuuming ring seat fixed around the bottom of the outer wall of the movable sleeve and a plurality of vacuuming heads arranged around the inner wall of the movable sleeve. One end of each vacuuming head is fixedly inserted into the inner side of the vacuuming ring seat, and a connecting tube is fixedly connected between the vacuuming ring seat and the suction end of the vacuum cleaner.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] (1) By setting up a protective mechanism, when the drill bit moves down to tap the slot of the aluminum part at the telescopic end of the cylinder, the telescopic shield and the annular connecting plate in the protective mechanism can move down together with the drill bit. Then the movable sleeve contacts the surface of the aluminum part in advance, and during the further downward movement of the drill bit, it is squeezed in the opposite direction and slides up relative to the outer wall of the fixed sleeve. In this way, the telescopic shield retracts, and without affecting the downward tapping of the drill bit, it can effectively cooperate with the annular connecting plate to provide a relatively closed tapping environment for the drill bit, so that the chips can be concentrated in the telescopic shield, avoiding a large amount of chips generated during tapping from splashing and affecting the processing.

[0012] (2) By setting the elastic element, when the movable sleeve accompanies the drill bit down to contact the aluminum part, and during the further downward movement of the drill bit, it is subjected to reverse compression and slides up relative to the outer wall of the fixed sleeve, the slider can simultaneously fix the sleeve to slide down the inner side of the movable groove and compress the slider deformation. In this way, the elastic force of the slider can effectively provide a certain downward pressure to the movable sleeve, thereby enhancing the clamping effect of the movable sleeve on the aluminum part and relatively improving the stability of the aluminum part during processing.

[0013] (3) By setting up the dust collection component and the dust collector, when the drill bit is tapping under the protection of the telescopic shield and the annular connecting plate, the dust collector is turned on. The suction end of the dust collector is continuously attracted by the connecting pipe to the inside of the dust collection ring seat, so that the dust collection head continuously sucks up and handles the debris generated during the drill bit tapping process. This eliminates the need for manual subsequent separate handling of debris, reduces labor intensity, and enhances practicality. Attached Figure Description

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Reference Figure 1-3 As shown, a tapping machine for machining screw holes in aluminum parts includes a base 1, a bracket 2 fixed in an inverted L shape on the side of the top surface of the base 1, and a cylinder 3 installed on the inner wall of the top of the bracket 2. A motor 4 is installed on the telescopic end of the cylinder 3, and a drill bit 5 is fixed on the output end of the motor 4.

[0021] In use, place the aluminum part on the base 1 beforehand and adjust its position so that the hole to be processed on the aluminum part corresponds to the drill bit 5. Then turn on the cylinder 3 and the motor 4. The output end of the motor 4 continuously causes the drill bit 5 to rotate, and the extension end of the cylinder 3 causes the drill bit 5 to move toward the hole in the aluminum part. Thus, the rotating drill bit 5 can effectively perform thread processing on the hole in the aluminum part.

[0022] Furthermore, referring to Figure 2 and Figure 3 As shown, it is worth noting that a protective mechanism is also included to prevent debris from splashing and interfering with the processing.

[0023] The protective mechanism includes a telescopic cover sleeve covering the outside of the motor 4 and an annular connecting plate 8 fastened to the telescopic rod of the cylinder 3. The telescopic cover sleeve is composed of a fixed sleeve 6 detachably set on the bottom surface of the annular connecting plate 8 and a movable sleeve 7 slidably fitted on the outer wall of the fixed sleeve 6. The lowest end of the movable sleeve 7 is located below the bottom end of the drill bit 5.

[0024] With the protective mechanism in place, when the drill bit 5 moves downwards to tap the grooves in the aluminum part at the telescopic end of the cylinder 3, the telescopic shield and the annular connecting plate 8 in the protective mechanism can move downwards together with the drill bit 5. The movable sleeve 7 then contacts the surface of the aluminum part in advance, and during the further downward movement of the drill bit 5, it is squeezed in the opposite direction and slides upwards along the outer wall of the fixed sleeve 6. In this way, the telescopic shield retracts, and without affecting the downward tapping of the drill bit 5, it can effectively cooperate with the annular connecting plate 8 to provide a relatively sealed tapping environment for the drill bit 5, so that the chips can be concentrated in the telescopic shield, avoiding a large amount of chips generated during tapping from splashing and affecting the processing.

[0025] Furthermore, by utilizing the detachable connection between the annular connecting plate 8 and the fixed sleeve 6, the fixed sleeve 6 can be periodically disassembled and separated from the annular connecting plate 8, thereby facilitating manual maintenance of the drill bit 5 and enhancing its practicality.

[0026] Furthermore, referring to Figure 3 As shown, it is worth noting that several movable grooves 9 are arranged around the inner wall of the movable sleeve 7, and elastic elements are provided in the movable grooves 9.

[0027] The elastic element includes a slider 10 that is slidably disposed in the inner side of the movable groove 9, and a compression spring 11 is fixed between the slider 10 and the inner wall at the bottom of the movable groove 9.

[0028] By setting the elastic element, when the movable sleeve 7 accompanies the drill bit 5 down to contact the aluminum part, and during the further descent of the drill bit 5, it is subjected to reverse compression and slides up relative to the outer wall of the fixed sleeve 6, the slider 10 can simultaneously fix the sleeve 6 to slide down inside the movable groove 9 and compress the slider 10 to deform. In this way, the elastic force of the slider 10 can effectively provide a certain downward pressure to the movable sleeve 7, thereby enhancing the clamping effect of the movable sleeve 7 on the aluminum part and relatively improving the stability of the aluminum part during processing.

[0029] Furthermore, referring to Figure 1-3 As shown, it is worth noting that a vacuum cleaner 14 is installed on the top surface of the base 1, and a vacuuming component that cooperates with the vacuum cleaner 14 is provided on the movable sleeve 7.

[0030] The vacuuming assembly includes a vacuuming ring seat 12 that is fixed around the bottom of the outer wall of the movable sleeve 7 and a plurality of vacuuming heads 13 that are arranged around the inner wall of the movable sleeve 7. One end of the vacuuming head 13 is fixedly inserted into the inner side of the vacuuming ring seat 12, and a connecting tube 15 is fixedly connected between the vacuuming ring seat 12 and the suction end of the vacuum cleaner 14.

[0031] With the setup of the dust collection assembly and the vacuum cleaner 14, when the drill bit 5 is tapping under the protection of the telescopic shield and the annular connecting plate 8, the vacuum cleaner 14 is turned on. The suction end of the vacuum cleaner 14 continuously forms a suction force on the inside of the dust collection ring seat 12 through the connecting pipe 15, causing the dust collection head 13 to continuously suck up and process the debris generated by the drill bit 5 during the tapping process. This eliminates the need for manual subsequent separate processing of debris, reduces labor intensity, and enhances practicality.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
