DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below through specific embodiments:

[0019] like Figure 1 as well as Figure 3 As shown, an embodiment of the present invention provides a multi-station external gear ring drilling device, comprising a drilling chamber 1, a positioning and clamping mechanism 2, a position adjustment mechanism 3, a flushing and cooling system 4, and a drilling rig 5;

[0020] Wherein, the positioning and clamping mechanism 2 is arranged in the middle of the drilling chamber 1 and is used to position and fix the outer gear ring;

[0021] The position adjustment mechanism 3 is arranged in the drilling chamber 1 and connected to the positioning and clamping mechanism 2, and is used to rotate or vertically move the positioning and clamping mechanism 2;

[0022] The flushing and cooling system 4 is arranged in the drilling chamber 1 and distributed outside the positioning and clamping mechanism 2, and is used for flushing and cooling the outer gear ring during processing;

[0023] There are multiple drilling rigs 5 and they are all placed in the drilling chamber 1 , and the multiple drilling rigs 5 are circumferentially distributed outside the positioning and clamping mechanism 2 .

[0024] In this embodiment:

[0025] The drilling chamber 1 includes a base and a protective cover arranged above the base. A door can be set on the front side of the protective cover. The staff can open this door to observe the positioning and clamping mechanism 2, position adjustment mechanism 3, flushing and cooling system 4, and drilling machine 5 in the protective cover. A hole can also be opened on the top of the protective cover. This multi-station external gear ring drilling equipment can be used with a robot. The robot grabs an external gear ring and extends it into the protective cover through this hole. The external gear ring is placed on the positioning and clamping mechanism 2 to position and fix it. Then, multiple drilling machines 5 are used to drill holes in the external gear ring simultaneously, and the flushing and cooling system 4 is used to cool the drilling process and remove waste chips. At the same time, the position adjustment mechanism 3 rotates or moves the positioning and clamping mechanism 2 vertically, thereby driving the fixed external gear ring to rotate a certain angle or adjust a certain height along the circumferential direction or axial direction of the external gear ring to efficiently drill a number of required holes on the external gear ring. After drilling is completed, the robot extends through this hole again to remove the processed external gear ring, thereby continuously processing.

[0026] In consideration of space layout and other factors, five drills 5 are used in this embodiment, each of which is equipped with a cooling nozzle. When the drill 5 is drilling, the cooling nozzle sprays coolant onto the drill bit of the drill 5 to cool the drill bit, preventing it from overheating during drilling, thereby improving the drilling quality of the outer gear ring.

[0027] like Figure 1 As shown, according to another embodiment of the present invention, the multi-station external gear ring drilling equipment further includes an auxiliary positioning structure 6, which is arranged in the drilling chamber 1 and located on the outside side of the positioning clamping mechanism 2, and is used to abut against the external gear ring during external gear ring processing.

[0028] When the outer gear ring is in the process of drilling, the auxiliary positioning structure 6 is offset against the outer side of the outer gear ring to improve the stability of the outer gear ring during the drilling process, thereby improving the drilling quality and accuracy of the outer gear ring to meet the high requirements of production; when the outer gear ring completes a drilling and needs to adjust the position of the outer gear ring, the auxiliary positioning structure 6 is disengaged from the outer gear ring and offsets it, and the auxiliary positioning structure 6 will not hinder the adjustment of the outer gear ring.

[0029] In this embodiment:

[0030] The auxiliary positioning structure 6 includes a telescoping device 61 . The telescoping device 61 is disposed in the drilling chamber 1 and an active end thereof is fixedly connected to a positioning rod 62 arranged toward the positioning clamping mechanism 2 .

[0031] Here, the retractor 61 may be a pneumatic cylinder to move the positioning rod 62, thereby causing the positioning rod 62 to abut against the outer side of the outer gear ring or to disengage from the outer gear ring. The flattened active end of the positioning rod 62 allows it to extend into the tooth groove of the outer gear ring, creating a larger contact area. This helps improve the stability of the outer gear ring when the positioning rod 62 abuts against the outer gear ring, further enhancing the processing quality of the outer gear ring.

[0032] like Figure 1 As shown, according to another embodiment of the present invention, a multi-station external gear ring drilling equipment, wherein the flushing and cooling system 4 includes a buffer box 41, and the buffer box 41 is multiple and circumferentially arranged on the outside of the positioning and clamping mechanism 2 and multiple buffer boxes 41 are connected, and each buffer box 41 is arranged with multiple spray pipes 42.

[0033] In this embodiment:

[0034] There are three buffer boxes 41, which are distributed on the front, rear and right sides of the positioning and clamping mechanism 2.

[0035] Distributed on the left side of the positioning and clamping mechanism 2 for reasonable distribution; the front buffer box 41 and the right buffer box 41 as well as the right buffer box 41 and the rear buffer box 41 are connected by a conducting pipe, and one of the buffer boxes 41 is connected to a liquid inlet pipe to ensure that the three buffer boxes 41 are filled with flushing liquid with a certain pressure; during the processing of the outer gear ring, the flushing liquid is sprayed from each spray pipe 42, and the spray pipes 42 are adjusted to be arranged toward the outer gear ring, so as to cool the outer gear ring during processing and take away the waste chips generated during the processing. This multi-station outer gear ring drilling equipment can also be provided with a waste liquid collection system to collect the waste liquid generated during the processing of the outer gear ring to prevent the waste liquid from flowing around and affecting the working environment; the waste liquid can also be filtered through a filtration system and then reused.

[0036] like Figure 1 as well as Figure 3 As shown, according to another embodiment of the present invention, a multi-station external gear ring drilling device, wherein the position adjustment mechanism 3 includes a height adjuster 31, the height adjuster 31 is arranged in the drilling chamber 1 and the active end at the top thereof is fixedly connected to a rotator 32, and the active end of the rotator 32 is connected to the positioning clamping mechanism 2.

[0037] In this embodiment:

[0038] The height adjuster 31 can be a cylinder, and the rotator 32 can be a motor. The height adjuster 31 operates through the rotator 32 to drive the positioning clamping mechanism 2 to move in the vertical direction, thereby driving the outer gear ring in the processing process to move in the axial direction of the outer gear ring to drill different holes in the axial direction of the outer gear ring; the rotator 32 operates to rotate the positioning clamping mechanism 2 to drive the outer gear ring in the processing process to rotate in the circumferential direction of the outer gear ring, thereby adjusting the angle of the outer gear ring to process holes at different circumferential positions of the outer gear ring to efficiently complete the drilling requirements of the outer gear ring.

[0039] like Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, the multi-station external gear ring drilling device, wherein the positioning clamping mechanism 2 includes a multi-jaw chuck 21 and an axial position adjustment portion;

[0040] The multi-jaw chuck 21 is connected to the position adjustment mechanism 3 , and each jaw of the multi-jaw chuck 21 is connected to a positioning portion 22 located at the top thereof, and the multiple positioning portions 22 are cocircularly arranged.

[0041] In this embodiment:

[0042] If the multi-jaw chuck 21 is a three-jaw chuck, then there are also three corresponding positioning parts 22. The bottom of the chuck body of the three-jaw chuck is connected to the active end of the rotator 32 through a mounting seat. The outer ring gear is placed outside the three positioning parts 22. The three-jaw chuck is operated to move the three positioning parts 22 away from each other until the three positioning parts 22 abut against the inner side wall of the outer ring gear, thereby completing the positioning and fixing of the outer ring gear. After the outer ring gear is processed, the three-jaw chuck is operated to move the three positioning parts 22 toward each other. The three positioning parts 22 are disengaged from the inner side wall of the outer ring gear, and the outer ring gear can be removed. Here, the three positioning parts 22 can be three arc-shaped thick blocks, which cooperate to abut against the inner side of the outer ring gear to stably position and fix the outer ring gear.

[0043] When the drill bit of the drilling rig 5 is drilling, if an error occurs, the drill bit may drill a hole in the positioning portion 22, thereby damaging the positioning portion 22; here, the positioning portion 22 may also be other structures instead of an arc-shaped thick block; at this time, the axial position adjustment portion is connected to each positioning portion 22, and is used to synchronously adjust the axial contact position of multiple positioning portions 22 with the inner side of the fixed outer gear ring.

[0044] The three positioning parts 22 are synchronously adjusted by the axial position adjustment part so that the three positioning parts 22 can stagger the drilling positions of the outer gear ring to prevent the positioning parts 22 from being drilled.

[0045] Based on the above scheme:

[0046] Each of the positioning parts 22 used includes a positioning piece 221. There are two positioning pieces 221 and they are arranged in parallel up and down. The two positioning pieces 221 are connected to the corresponding claws of the multi-claw chuck 21. The axial position adjustment part is connected to both positioning pieces 221 to make the two positioning pieces 221 move toward or away from each other.

[0047] Among them, each positioning piece 221 is specifically an arc-shaped thin block, so that there is a larger contact area between the positioning piece 221 and the outer ring gear, thereby improving the positioning stability of the outer ring gear; the two positioning pieces 221 in each positioning part 22 are synchronously adjusted to move toward or away from each other through the axial position adjustment part to stagger the positions of the drill holes on the outer ring gear; at the same time, multiple positioning pieces 221 are cooperated to press against the inner side of the outer ring gear for positioning and fixing.

[0048] In the present invention:

[0049] Each positioning piece 221 is provided with an adjustment hole 222 along the movement direction of the corresponding claw. The axial position adjustment portion includes a guide rod 23, a movable block 24 and an adjustment structure.

[0050] Wherein, at least one of the guide rods 23 is connected between the two positioning pieces 221 in each positioning portion 22 and one end of the guide rod 23 is fixedly connected to the corresponding claw, and the other end of the guide rod 23 freely passes through the corresponding two positioning pieces 221;

[0051] The movable block 24 is arranged in each adjustment hole 222 so as to slide along the moving direction of the corresponding claw.

[0052] The adjustment structure is connected to each movable block 24 .

[0053] Here, there are two guide rods 23 between the two positioning pieces 221 in each positioning part 22, and they are arranged vertically at intervals. The two guide rods 23 guide the movement of the two positioning pieces 221, and the movable block 24 is slidably arranged in the adjustment hole 222. When the three-jaw chuck runs to drive the positioning piece 221 to move through the guide rod 23, the adjustment hole 222 provides a clearance space for the movable block 24 to prevent the movable block 24 from hindering the movement of the positioning piece 221; at the same time, the adjustment structure can also make the movable block 24 move to drive the two positioning pieces 221 in the three positioning parts 22 to move toward or away from each other, so that the positioning piece 221 is staggered from the position of the drilling hole on the outer gear ring, ensuring the safety of the positioning part 22 during the drilling process.

[0054] Furthermore, the adjustment structure used includes an adjustment screw 25 and a rotating shaft 26;

[0055] The adjusting screw 25 is threadedly connected between the two positioning pieces 221 in each positioning portion 22, and one end of the adjusting screw 25 is rotatably connected to the chuck body of the multi-jaw chuck 21;

[0056] The rotating shaft 26 is rotatably connected to the middle of the chuck body of the multi-jaw chuck 21 and is transmission-connected to each adjusting screw 25 .

[0057] Among them, one end of the rotating shaft 26 can be driven to rotate by a motor fixedly installed on the chuck body of the multi-jaw chuck 21, and a belt can be used to drive the rotating shaft 26 and one end of each adjusting screw 25 to make multiple rotating shafts 26 rotate synchronously, so that the two positioning plates 221 in each positioning part 22 move toward or away from each other, and the positioning plates 221 stagger the position of the drilling holes on the outer gear ring to ensure the safety of the positioning part 22 during the drilling process.

[0058] The specific operation process of this program is as follows:

[0059] 1. Use a manipulator to place the outer gear ring on the outside of multiple mounting parts. The rear multi-claw chuck 21 operates, and multiple mounting parts are used to position and fix the outer gear ring. The rear telescoping device 61 operates, and the positioning rod 62 abuts against the outer gear ring.

[0060] 2. The drilling machine 5, the cooling nozzle and the liquid spray pipe 42 are all operated to drill a hole in the outer wall of the outer gear ring;

[0061] 3. The telescopic device 61 runs in the reverse direction, the positioning rod 62 is disengaged from the outer gear ring and abuts against it, the rotator 32 runs, the outer gear ring rotates a certain angle, and then the telescopic device 61 runs again, the positioning rod 62 abuts against the outer gear ring, and holes are drilled at different positions along the circumferential direction of the outer gear ring;

[0062] 4. The telescopic device 61 is operated in the reverse direction again, the positioning rod 62 is disengaged from the outer gear ring and abuts against it, the height adjuster 31 is operated, the outer gear ring is adjusted to a certain height in the vertical direction, and at the same time the shaft 26 rotates to make the positioning piece 221 stagger the position of the drilling hole on the outer gear ring. Then the telescopic device 61 is operated again, the positioning rod 62 abuts against the outer gear ring, and the drilling machine 5 is used to drill holes at different positions along the axial direction on the outer side of the outer gear ring;

[0063] 5. After the outer gear ring is drilled, multiple mounting parts are separated from the outer gear ring, all equipment stops running, and the robot removes the outer gear ring.

[0064] The above process can be controlled and operated by a central controller for automatic and continuous processing.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
