DETAILED DESCRIPTION

[0051] The application will be further described below in conjunction with the drawings.

[0052] In the description of the present application, it should be understood that the orientation description, such as the orientation or position relationship indicated by up, down, front, back, left, right and the like, is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as a limitation on the present application that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0053] The toothed claw milling weld joint process disclosed in the embodiments of the present application is used to improve the processing efficiency of multiple toothed claws 5, and three toothed claws 5 are taken as an example in the embodiments of the present application.

[0054] A toothed claw milling weld joint process comprises the following steps:

[0055] Positioning, positioning by abutting against the first mounting plane 5111 and the second mounting plane 5112 of the toothed claw 5, and ensuring that the three toothed claws 5 are all positioned;

[0056] Clamping, arranging the three toothed claws 5 in sequence in the circumferential direction, and simultaneously applying force to the tail parts 52 on the three toothed claws 5 to ensure that the three toothed claws 5 are clamped at equal angles in the circumferential direction;

[0057] Milling, sequentially milling the toothed claws 5 two by two until two weld joints are milled on each of the three toothed claws 5;

[0058] The implementation principle of the milling and welding process of the toothed palm in this embodiment is as follows: the first mounting plane 5111 and the second mounting plane 5112 of the toothed palm 5 are used for abutment and positioning. After all three toothed palms 5 are positioned, force is applied to the tails 52 of the three toothed palms 5 at the same time so that the three toothed palms 5 are clamped at the same time. Under the state of multiple toothed palms 5 being clamped, the toothed palms 5 are continuously milled in pairs until two weld seams are milled on each toothed palm 5. The process designed in this way can improve the processing efficiency of the toothed palms 5.

[0059] This application also discloses a milling and welding machine capable of performing the above-described milling and welding process for toothed teeth. It is used to mill two weld seams on each of a plurality of toothed teeth 5; here, we continue to use three toothed teeth 5 as an example. (Refer to...) Figure 2 The tooth milling welding equipment includes a mounting plate 1, on which a frustum plate 11 is provided, combined with... Figure 3 The top of the frustum plate 11 is used to place three toothed claws 5, and the frustum plate 11 can rotate on the mounting plate 1; a positioning element 12 is provided at the center of the top of the frustum plate 11, which is used to position the three toothed claws 5 at equal angles along the circumferential direction; the mounting plate 1 is also provided with a drive mechanism 2 for driving the frustum plate 11 to rotate and a milling mechanism 3 for milling two toothed claws 5 at the same time; the frustum plate 11 is also provided with a clamping mechanism 4 for clamping the three toothed claws 5 at the same time.

[0060] First, place the three toothed plates 5 on the frustum plate 11, ensuring that all three toothed plates 5 abut against the positioning member 12. Then, drive the clamping mechanism 4 to clamp the three toothed plates 5 simultaneously. At this time, drive the milling mechanism 3 to mill weld seams on the two toothed plates 5 to be milled. After the weld seams are milled, drive the drive mechanism 2 to rotate the frustum plate 11 and then perform milling again. Repeat the above operation to mill the three toothed plates 5 relatively quickly.

[0061] Reference Figure 4 The positioning component 12 is a Y-shaped positioning frame. Three positioning areas 110 are formed circumferentially between the side wall of the Y-shaped positioning frame and the upper surface of the frustum plate 11. Within each positioning area 110, the positioning component 12 has adjacent first positioning surfaces 121 and second positioning surfaces 122. Both the first and second positioning surfaces 121 are perpendicular to the horizontal plane, and the minimum included angle between them is 120°. Figure 1 The first positioning surface 121 is used to fit with the first mounting surface 5111, and the second positioning surface 122 is used to fit with the second mounting surface 5112. The first positioning surface 121 and the second positioning surface 122 are used to position the palm 5.

[0062] The positioning process of the three toothed palps 5 is the same, taking one of the toothed palps 5 as an example: first, the toothed palp 5 needs to be placed in the positioning area 110, and then the first positioning surface 121 is made to be in close contact with the first installation plane 5111, and the second positioning surface 122 is made to be in close contact with the second installation plane 5112, so that the positioning is completed.

[0063] Referring to Figure 4 , the upper end surface of the positioning member 12 is provided with a downwardly non-penetrating matching hole 123, which helps to put in a screw. The positioning member 12 is installed on the circular table plate 11 by the screw. When milling toothed palps 5 of different sizes is required, different sizes of positioning members 12 can be replaced to ensure that the three toothed palps 5 are positioned.

[0064] Referring to Figure 3 and Figure 4 , the clamping mechanism 4 includes a disc plate 41, which is provided at the central position of the bottom end of the circular table plate 11 and is an integral part of the circular table plate 11. The disc plate 41 can rotate synchronously with the circular table plate 11. The installation plate 1 is provided with a receiving groove 13 for the disc plate 41 to be placed in. At this time, the lower end surface of the circular table plate 11 is in abutment with the upper end surface of the installation plate 1, and the disc plate 41 is located in the receiving groove 13.

[0065] Referring to Figure 5 and Figure 6 , the disc plate 41 is internally provided with a cavity 411 that penetrates into the interior of the circular table portion. The cavity 411 is provided with a gear 42, which is coaxially arranged with the circular table plate 11 and can rotate. In order to achieve simultaneous clamping of the three toothed palps 5, three racks 43 are sequentially arranged between the gear 42 and the disc plate 41 in the circumferential direction. Each rack 43 is internally provided with a through guide hole 432. Each guide hole 432 is provided with a guide rod 45. Each guide rod 45 is supported in the cavity 411 by a fixed block. The guide rod 45 is used to guide the movement direction of the rack 43. Each rack 43 cooperates with the gear 42. Each rack 43 is provided with a clamping block 44 on the upper end surface for clamping the toothed palp 5. The rack 43 is provided with a plurality of inclined grooves 431. The clamping block 44 is provided with a plurality of inclined edges 441. The inclined edges 441 are clamped in the inclined grooves 431. In combination Figure 3 , each clamping block 44 extends to one side of the positioning member 12. The circular table plate 11 is provided with a guide groove 112 corresponding to each clamping block 44, which penetrates into the cavity 411. The clamping block 44 is provided in the guide groove 112. The guide groove 112 is used to guide the movement direction of the clamping block 44, so that the clamping block 44 can move towards or away from the positioning member 12. The clamping surface of the clamping block 44 is also provided with a rubber pad 442, which is used to protect the structure of the toothed palp 5.

[0066] To clamp the three toothpads 5 on the positioning member 12, the gear 42 needs to be rotated clockwise, which will drive the three racks 43 to move simultaneously. Through the cooperation of the inclined edges 441 and the inclined grooves 431, the simultaneous movement of the three racks 43 will drive the three clamping blocks 44 to move towards the positioning member 12, at which time the action of simultaneously clamping the three toothpads 5 by the three clamping blocks 44 can be realized.

[0067] With reference to Figure 5 and Figure 6 , in order to facilitate the rotation of the gear 42, the leftmost rack 43 and the cooperating guide rod 45 are threadedly connected, and rotating the guide rod 45 can make the rack 43 move transversely; in order to facilitate the rotation of the guide rod 45, the end of the guide rod 45 is also provided with a driven bevel gear 46 coaxial with the guide rod 45, and a driving bevel gear 47 is cooperatively arranged on the driven bevel gear 46. The upper end surface of the driving bevel gear 47 is provided with a driving rod 48 extending upward to the outside, and the top of the driving rod 48 is fixedly provided with a rotating disc 49. The driving rod 48 and the circular table plate 11 are movably arranged and provided with a bearing for supporting the driving rod 48. The upper end surface of the rotating disc 49 is provided with a square countersunk hole 491, which can facilitate the rotation of the rotating disc 49 with a tool.

[0068] To facilitate the rotation of the gear 42, the rotating disc 49 needs to be rotated, which will drive the driving rod 48 to rotate, and then drive the driving bevel gear 47, the driven bevel gear 46 and the guide rod 45 to rotate. The rotation of the guide rod 45 will drive the rack 43 cooperating with it to move, and the movement of the rack 43 will drive the gear 42 to rotate.

[0069] With reference to Figure 7 , the milling mechanism 3 comprises a first moving member 31, which is a gas cylinder. The first moving member 31 is arranged on the mounting plate 1 to the right of the circular table plate 11. A fixed plate 32 is arranged on the output end of the first moving member 31, and a second moving member 33 is fixedly arranged on the fixed plate 32. The second moving member 33 is also a gas cylinder. The first moving member 31 is used to drive the fixed plate 32 to move transversely and reciprocally, so as to drive the second moving member 33 to move transversely and reciprocally. A fixed frame is arranged on the output end of the second moving member 33, and the second moving member 33 is used to drive the fixed frame to move in the vertical direction. At least two disc cutters 34 for milling welds are arranged on the fixed frame. In the embodiment of the present application, two disc cutters 34 are arranged in parallel and at the same height. A motor can be used to drive the two disc cutters 34 to rotate. The specific driving structure is a prior art, and therefore will not be described here.

[0070] To mill the toothpads 5, the first moving member 31 needs to be driven to drive the two disc cutters 34 to approach the toothpads 5, and then the second driving member 23 can be driven to make the two disc cutters 34 mill the two welds from top to bottom along the vertical direction.

[0071] Referring to Figure 7 Specifically, each two adjacent positioning areas 110 are provided with a cutting area 113, and two disc cutters 34 can simultaneously mill the positions to be milled on the adjacent two toothed palps 5 in the same cutting area 113, that is, a weld can be milled on each of the two adjacent toothed palps, and since the two disc cutters 34 are arranged in parallel and at the same height, the two welds have the same length and are parallel, which can minimize the damage to the side wall of the toothed palps 5 caused by welding when the three toothed palps are welded and assembled into a drill bit, thereby facilitating the subsequent installation of the drill bit.

[0072] Referring to Figure 8 The driving mechanism 2 comprises a mounting frame 21 arranged on the mounting plate 1, and the mounting frame 21 is provided with a first driving member 22, which is a pneumatic cylinder. The output end of the first driving member 22 is provided with a second driving member 23, which is a rotary pneumatic cylinder. The first driving member 22 is used to drive the second driving member 23 to make vertical reciprocating motion. The output end of the second driving member 23 is provided with a matching block 24 inserted into the matching hole 123, and the second driving member 23 is used to drive the matching block 24 to be inserted into the matching hole 123, so as to drive the circular table plate 11 to rotate at a fixed angle of 120°.

[0073] Referring to Figure 9 and Figure 10 In order to ensure that the circular table plate 11 can rotate relative to the mounting plate 1, the bottom of the circular table plate 11 is circumferentially fixed with a plurality of accommodating members 114, each of which is movably provided with a rolling body 1141. The mounting plate 1 is provided with a ring groove 14, and each of the accommodating members 114 is located in the ring groove 14 and the bottom of the rolling body 1141 is attached to the inner bottom of the ring groove 14. A plurality of rolling bodies 1141 can assist the rotation of the circular table plate 11. The bottom of the disc plate 41 is also provided with a plurality of clamping hooks 412, and the bottom surface of the accommodating groove 13 is provided with a circular ring groove 15, and the circular ring groove 15 is provided with a ring belt 111 for clamping the clamping hooks 412. The ring belt 111 is used to prevent the bottom of the rolling body 1141 from being separated from the inner bottom of the ring groove 14.

[0074] In order to make the circular table plate 11 rotate, the first driving member 22 needs to drive the second driving member 23 to move downward so that the matching block 24 is inserted into the matching hole 123, and then the second driving member 23 is driven to rotate the matching block 24, which in turn drives the circular table plate 11 to rotate and makes the two disc cutters 34 reach the three cutting areas 113 in turn, thereby realizing the milling rotation of the two toothed palps 5.

[0075] The implementation principle of the toothed pallet milling weld seam process in the embodiment of the application is as follows: firstly, the three toothed pallets 5 are respectively placed in the three positioning areas 110, and each toothed pallet 5 is attached to the positioning member 12 to complete positioning, then the tool is used to rotate the rotating disc 49 clockwise to rotate the gear 42 clockwise, at this time, the gear 42 drives the three clamping blocks 44 to move towards the positioning member 12, and the three clamping blocks 44 simultaneously clamp the three toothed pallets 5, then the first moving member 31 is driven to drive the two disc knives 34 to reach the cutting area 113, then the second driving member 23 is driven to drive the two disc knives 34 to mill two weld seams from top to bottom along the vertical direction, after the milling is completed, the second driving member 23 is driven to reset, then the first driving member 22 is driven to drive the second driving member 23 to move downwards so that the matching block 24 is inserted into the matching hole 123, and the second driving member 23 is driven to drive the matching block 24 to rotate 120°, the rotation of the matching block 24 drives the circular table plate 11 to rotate 120°, then the above operation is repeatedly completed, and the two disc knives 34 can reach the three milling areas in turn to mill the toothed pallets 5 two by two.

[0076] The embodiments of the specific implementation are the preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
