[0080] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of the present invention, but it is not intended to limit the scope of protection of the claims attached to the present invention.

[0081] like Figure 1 As shown, the automatic drilling and tapping device for both ends of shaft parts of the present invention comprises a first bracket 100 and a second bracket 200, and the first bracket 100 and the second bracket 200 are arranged opposite to each other to support the components of the whole device. The automatic drilling and tapping device for both ends of shaft parts of the present invention also comprises a progressive material transfer mechanism 300, a support mechanism 400, a drilling mechanism 500, a tapping mechanism 600 and a slag blowing mechanism 700, wherein the progressive material transfer mechanism 300 is arranged between the first bracket 100 and the second bracket 200, and the support mechanism 400, the drilling mechanism 500, the tapping mechanism 600 and the slag blowing mechanism 700 are connected to the first bracket 100 and the second bracket 200 respectively.

[0082] The progressive material moving mechanism 300 has a progressive material moving direction X, and includes a first end 300a and a second end 300b arranged along the progressive material moving direction X, the first end 300a being a loading end, and the second end 300b being a unloading end. The support mechanism 400 is relatively arranged on the first bracket 100 and the second bracket 200 along the progressive material moving direction X, that is, the support mechanism 400 is two or two groups. There are at least two drilling mechanisms 500, tapping mechanisms 600 and slag blowing mechanisms 700, respectively, and are relatively arranged on the first bracket 100 and the second bracket 200 along an axis parallel direction Y perpendicular to the progressive material moving direction X, so as to perform drilling, tapping and slag blowing operations, respectively. The drilling mechanism 500, the tapping mechanism 600 and the slag blowing mechanism 700 are sequentially arranged on the outside of the support mechanism 400 along the progressive material moving direction X, as shown in FIG. Figure 1 As shown, on the first bracket 100, the drilling mechanism 500a, the tapping mechanism 600a and the slag blowing mechanism 700a are sequentially arranged on the outer side of the support mechanism 400a away from the progressive material moving mechanism 300 along the progressive material moving direction X; on the second bracket 200, the drilling mechanism 500b, the tapping mechanism 600b and the slag blowing mechanism 700b are sequentially arranged on the outer side of the support mechanism 400b away from the progressive material moving mechanism 300 along the progressive material moving direction X. Generally speaking, the support mechanism 400a, the drilling mechanism 500a, the tapping mechanism 600a and the slag blowing mechanism 700a are axially symmetrical with the support mechanism 400, the drilling mechanism 500b, the tapping mechanism 600b and the slag blowing mechanism 700b with the center line of the progressive material moving mechanism 300 along the progressive material moving direction X as the axis, and the drilling, tapping, slag blowing and material moving mechanisms are operated simultaneously to realize simultaneous processing of both ends of the workpiece.

[0083] In detail, the progressive material transfer mechanism 300 loads the workpiece from the first end 300a, and progressively transfers the workpiece along the progressive material transfer direction X and supports the workpiece at each processing station through the support mechanism 400a. At each processing station, the drilling mechanism 500, the tapping mechanism 600 and the slag blowing mechanism 700 respectively perform drilling, tapping and slag blowing on both ends of the workpiece until the progressive material transfer mechanism 300 advances the workpiece to the second end 300b for unloading.

[0084] The automatic drilling and tapping equipment for both ends of shaft parts of the present invention saves time and effort, has high efficiency, and has high processing quality stability, and is particularly suitable for the needs of large-scale processing.

[0085] Furthermore, the automatic drilling and tapping equipment for both ends of shaft parts of the present invention further includes a loading device 10 and a unloading device 20 respectively provided at the first end 300a and the second end 300b.

[0086] The automatic drilling and tapping equipment at both ends of shaft parts of the present invention is connected with the automatic loading and unloading devices of shaft parts to realize the continuous production of automatic loading, processing and unloading of parts, and the unloading device can be combined with subsequent processing equipment to form an intelligent production line.

[0087] The first bracket 100 or the second bracket 200 is a movable bracket that can move along the axis parallel direction Y. Figure 2 As shown, the first bracket 100 and the second bracket 200 are arranged on the equipment frame 801, the first bracket 100 is a movable bracket, and the second bracket 200 is a fixed bracket, that is, the first bracket 100 is movably connected to the equipment frame 801, and the second bracket 200 is fixedly connected to the equipment frame 801. The first bracket 100 is moved along the axis parallel direction Y through, for example, a linear guide 802 and a travel motor 803 driving the linear guide 802.

[0088] During the movement of the first bracket 100 along the axis-parallel direction Y, the supporting mechanism 400a, the drilling mechanism 500a, the tapping mechanism 600a and the slag blowing mechanism 700a fixed thereon and a part of the progressive material moving mechanism 300 fixed thereon follow and realize reciprocating movement to adjust the distance between the first bracket 100 and the second bracket 200 to cope with the processing of workpieces of different lengths.

[0089] The drilling mechanism 500 is a plurality of relatively arranged groups, for example Figure 1 In the embodiment shown, the drilling mechanism 500 includes a group of drilling mechanisms 500a1, 500b1 for bottom hole processing and a group of drilling mechanisms 500a2, 500b2 for hole expansion processing. In the present invention, the drilling mechanism 500, the tapping mechanism 600 and the slag blowing mechanism 700 can be set as one or more groups to meet the process requirements.

[0090] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the structures of the drilling mechanism 500 and the tapping mechanism 600 are the same, and drilling or tapping can be achieved by replacing the working parts. Taking the working part as a drill bit as an example, the drilling mechanism 500 includes a drill bit 510, a chuck 520, a support seat 530, a dynamic torque sensor 540, a rotating motor 550, a propulsion screw 560 and a propulsion motor 570. The drill bit 510 is fixed in the chuck 520, and the chuck 520 is connected to the support seat 530. The support seat 530 is connected to the rotating motor 550 through the dynamic torque sensor 540, and the rotating motor 550 drives the drill bit 510 to rotate. When the drill bit 510 is replaced with a tap, the tapping mechanism 600 is formed.

[0091] The dynamic torque sensor 540 is used to detect the dynamic torque value changes during drilling or tapping. During normal operation, the torque value may have a small floating change. Through the data mutation, it is judged whether the drill bit and tap state need to be replaced. The propulsion motor 570 rotates to drive the propulsion screw 560 to realize the reciprocating movement of the drill bit or tap of the working part. In addition, according to the tap parameters, the propulsion motor 570 cooperates with the component rotation motor 550 to realize the processing of threads with different pitches by changing the motor rotation speed.

[0092] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, specifically, the slag blowing mechanism 700 includes a slag blowing port 710, a moving plate 720, a support plate 730, a guide rail 740 and a moving cylinder 750. The guide rail 740 and the moving cylinder 750 are fixed on the support plate 730. The slag blowing port 710 is fixed on the moving plate 720. The moving plate 720 can reciprocate along the guide rail 740 by the drive of the moving cylinder 750. Compressed air can be introduced into the slag blowing port 710 to clean the residual iron chips and coolant left by the end surface of the workpiece.

[0093] like Figure 1 and Figure 2 As shown, the support mechanism 400 includes a drilling support station 410, a tapping support station 420 and a slag blowing support station 430 corresponding to the drilling mechanism 500, the tapping mechanism 600 and the slag blowing mechanism 400 respectively. Figure 1 As shown, the support mechanism 400 has two sets of drilling support stations 410, one set of tapping support stations 420, and one set of slag blowing support stations 430. It should be noted that the number and position of the drilling support stations 410, the tapping support stations 420, and the slag blowing support stations 430 are specifically determined according to the number and position of the drilling mechanism 500, the tapping mechanism 600, and the slag blowing mechanism 700. The drilling support stations 410, the tapping support stations 420, and the slag blowing support stations 430 can be, for example, V-block shaped to limit the workpiece at the process position, but the present invention is not limited thereto.

[0094] In one embodiment of the present invention, Figure 2 and Figures 5 to 7As shown, the progressive material transfer mechanism 300 is a parallelogram mechanism, and the progressive material transfer mechanism 300 includes a material transfer plate 330, and the material transfer plate 330 is formed by the connecting rod of the parallelogram mechanism. There are multiple material transfer seats 340 on the material transfer plate 330, and the material transfer seat 340 has a pick-up position A and a placement position B. Along the progressive material transfer direction X, the pick-up position A and the placement position B correspond to two adjacent workstations respectively. In detail, the progressive material transfer mechanism 300 also includes a driving member 310 and a swing rod 320, and the driving member 310 is fixed on the first bracket 100 and the second bracket 200. The driving member 310 drives two parallel swing rods 320 to swing, so that the material transfer plate 330 connected to the swing rod 320 has different height positions and realizes reciprocating material transfer action. Wherein, along the progressive material transfer direction X, the placement position B is located in front of the pick-up position A. The stepping distance from the pick-up position A to the placement position B is equal to the distance between two adjacent workstations of the support mechanism 400. That is, when the material transfer plate 330 drives the plurality of material transfer seats 340 from the pick-up position A to the highest position C to the placement position B, each material transfer seat 340 picks up the workpiece at the previous station and lifts it up and then sequentially moves it to the next station to realize the workpiece progressive movement function. The material transfer seat 340 is, for example, a V-shaped seat structure.

[0095] The driving member 310 is, for example, a sprocket drive assembly, including a power sprocket 311, a tensioning sprocket 312, a synchronous sprocket 313, a chain 314 and a driving motor 315. The driving motor 315 drives the power sprocket 311. The power sprocket 311 drives the synchronous sprocket 313 to rotate through the chain 314. The tensioning sprocket 312 tensions the chain 314 to ensure that the moving side and the fixed side rotate synchronously. The tensioning sprocket 314 can be tightened automatically or manually.

[0096] like Figure 2 and Figures 8 to 9As shown, the automatic drilling and tapping device for both ends of shaft parts of the present invention also includes a workpiece clamping mechanism 900 arranged above the support mechanism 400. The workpiece clamping mechanism 900 includes a clamping drive 910 and a clamping block 950 driven by the clamping drive 910. The clamping block 950 is arranged corresponding to the drilling support station 410, the tapping support station 420 and the slag blowing support station 430 of the support mechanism 400, so as to be able to clamp the workpiece located on the drilling support station 410, the tapping support station 420 and the slag blowing support station 430, so as to facilitate the drilling mechanism 500, the tapping mechanism 600 and the slag blowing mechanism 700 to process the workpiece. In detail, the clamping drive 910 is a clamping cylinder, the workpiece clamping mechanism 900 also includes a guide rod 920, a guide bearing 930 and a clamping bracket 940, and the workpiece clamping mechanism 900 is fixed on the first bracket 100 and the second bracket 200 through the clamping bracket 940. Under the telescopic action of the clamping cylinder, the clamping block 950 can be lifted up and down through the guide rod 920 passing through the guide bearing 930, so as to clamp the workpiece when the drilling mechanism 500, the tapping mechanism 600 and the slag blowing mechanism 700 are working, and release the workpiece when the progressive material moving mechanism 300 moves the material.

[0097] In summary, the specific working process of the automatic drilling and tapping device for both ends of shaft parts of the present invention is as follows:

[0098] The workpiece is in the loading position and is centered.

[0099] The progressive material transfer mechanism 300 moves the workpiece to the drilling station.

[0100] Under the action of the clamping driving member 910 , the clamping block 950 of the workpiece clamping mechanism 900 cooperates with the drilling support station portion 410 of the drilling station to clamp the workpiece to prevent the workpiece from rotating.

[0101] The propulsion motor 570 of the drilling mechanism 500 rotates, and drives the drill bit 510 to move through the propulsion screw 560, so as to achieve simultaneous drilling at both ends of the workpiece.

[0102] After the drilling is completed, the workpiece clamping mechanism, under the action of the clamping driving member 910, the clamping block 950 rises and separates from the workpiece.

[0103] The progressive material transfer mechanism 300 drives the swing rod 320 to rotate under the action of the driving member 310, and the material transfer seat 340 progressively transfers the workpiece to the next process according to the designed spacing.

[0104] According to the above steps, the drilling and tapping processes are repeated until the slag blowing station.

[0105] After the workpiece is moved to the slag blowing station, the workpiece clamping mechanism 900, under the action of the clamping driving member 910, the clamping block 950 cooperates with the slag blowing supporting station portion 430 to clamp the workpiece to prevent the workpiece from rotating.

[0106] The slag blowing port 710 of the slag blowing mechanism 700 is guided by the guide rail 740 to move forward under the action of the moving cylinder 750, and the slag blowing port 710 moves to the end of the workpiece, and the residue at the end of the workpiece is blown away by compressed air.

[0107] After the slag blowing process is completed, the workpiece clamping mechanism, under the action of the clamping driving member 910, the clamping block 950 rises and separates from the workpiece.

[0108] The progressive material transfer mechanism 300 drives the swing rod 320 to rotate under the action of the driving member 310, and the material transfer seat 340 progressively transfers the workpiece to the unloading station of the next process according to the designed spacing.

[0109] The single piece processing is now completed.

[0110] The present invention can continuously load materials, and each time the progressive material transfer mechanism 300 moves, the workpieces on each station are sequentially advanced to the next process, thereby realizing continuous production.

[0111] In summary, the method for automatic drilling and tapping at both ends of a shaft part of the present invention comprises the following steps:

[0112] S100, the workpiece is loaded from the first end;

[0113] S200, the workpiece is advanced to the drilling station corresponding to the drilling mechanism through the progressive material transfer mechanism, and the drilling mechanism performs drilling processing on both ends of the workpiece;

[0114] S300, the workpiece is advanced to the tapping station corresponding to the tapping mechanism through the progressive material transfer mechanism, and the tapping mechanism performs tapping processing on both ends of the workpiece;

[0115] S400, the workpiece is advanced to the slag blowing station corresponding to the slag blowing mechanism through the progressive material transfer mechanism, and the slag blowing mechanism blows and cleans the slag at both ends of the workpiece;

[0116] S500, the workpiece is advanced to the second end for unloading through the progressive material transfer mechanism.

[0117] The drilling process in step S200, the tapping process in step S300 and the slag blowing and cleaning in step S400 can be performed multiple times according to the process requirements.

[0118] Each time the progressive material transfer mechanism moves, each workpiece at each station is advanced to the next process according to the designed spacing for continuous production.

[0119] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
