[0045] In the related art, a large number of mechanical connectors are welded on the cladding type embedded parts, and the mechanical connectors are usually a rotating body structure. The embedded parts welded with a large number of mechanical connectors need to be vertically installed on the large steel structure wall plate. There are a large number of mechanical connectors on the embedded parts, which are arranged closely. During installation, each mechanical connector needs to be able to penetrate the predetermined opening on the large steel structure wall and fit tightly with the large steel structure wall.

[0046] However, the embedded parts have a special structure, and some of them are large in size and weight, which exceeds the stroke or tightening force of the existing machine tool fixtures. As a result, the existing milling processing equipment has the disadvantages of difficulty in fixing the weld feet of mechanical connectors, low efficiency and high cost.

[0047] In addition, when welding mechanical connectors to embedded parts, the weld feet cannot be accurately controlled, and the size of the weld feet is often larger than the diameter of the mechanical connector, that is, the weld feet usually protrude from the outer surface of the mechanical connector. In addition, the tolerance of the wall opening size is small, and the tolerance of the mechanical connector diameter plus the weld foot size and the large steel structure wall opening is 1.5mm. Therefore, during the actual installation of embedded parts, the mechanical connector weld feet are often too large to penetrate the wall, resulting in difficulties in the installation of embedded parts. Therefore, the size of the mechanical connector weld feet needs to be corrected.

[0048] In view of this, the present application provides a weld leg milling device, including a guide, a milling machine body, a milling head and an adjusting member, wherein the guide is used to connect with a mechanical connector, the milling machine body is movably arranged on the guide, the milling head is arranged on the milling machine body, the milling head is at least used to mill the weld leg of the mechanical connector, and the adjusting member is arranged on the guide, and the adjusting member drives the milling machine body to approach or move away from the mechanical connector. The adjusting member can drive the milling machine body to slide along the guide, and the milling machine body can drive the milling head to approach or move away from the mechanical connector to achieve the adjustment of the feed and retract and the feed amount, so as to facilitate the milling of the weld leg of the mechanical connector, so that the mechanical connector can smoothly penetrate the wall, so as to facilitate the installation of the embedded parts.

[0049] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0050] See also Figure 1 The mechanical connector 5 used for milling in the present application comprises a sleeve 501, a first end of the sleeve 501 is provided with a tapered threaded hole 502, a second end of the sleeve 501 is welded to the embedded part 6 to form a weld foot 503, and the size of the weld foot 503 at the maximum diameter is larger than the outer diameter of the sleeve 501, that is, the weld foot 503 protrudes from the outer wall surface of the sleeve 501. The first end of the sleeve 501 is arranged opposite to the second end of the sleeve 501.

[0051] It should be noted that the present application can be used for the milling of weld legs of mechanical connectors during the installation phase of large steel structures and nuclear power equipment, and can also be used for milling processing before assembly of mechanical equipment with similar assembly requirements, and has a wide range of applications.

[0052] See also Figure 2-Figure 5 The present application provides a weld foot milling device, comprising a guide member 3, a milling machine body 1, a milling head 4 and an adjusting member 2, wherein the guide member 3 is used to be connected to a mechanical connector 5, and the milling machine body 1 is movably arranged on the guide member 3. Specifically, the guide member 3 and the mechanical connector 5 are detachably connected, that is, when the weld foot milling device mills the weld foot 503, the guide member 3 is fixedly connected to the mechanical connector 5; after the milling is completed, the guide member 3 is removed from the mechanical connector 5. The milling machine body 1 is slidably arranged on the guide member 3, and the milling machine body 1 can move along the length extension direction of the guide member 3.

[0053] In some embodiments of the present application, the milling head 4 is disposed on the milling machine body 1, and the milling head 4 is at least used to mill the weld feet 503 of the mechanical connector 5. Specifically, the milling head 4 is connected to the milling machine body 1, and the milling machine body 1 is located between the adjustment member 2 and the milling head 4. When the milling machine body 1 moves along the length extension direction of the guide member 3, the milling head 4 can move synchronously with the milling machine body 1.

[0054] In some embodiments of the present application, the adjusting member 2 is disposed on the guide member 3, and the adjusting member 2 drives the milling machine body 1 to approach or move away from the mechanical connector 5. In the process of the milling machine body 1 approaching or moving away from the mechanical connector 5, the milling machine body 1 synchronously drives the milling head 4 to approach or move away from the mechanical connector 5, so that the milling head 4 can mill the weld foot 503 of the mechanical connector 5.

[0055] It should be noted that the adjusting member 2 can drive the milling machine body 1 to slide along the guide member 3 to drive the milling head 4 to approach or move away from the mechanical connector 5. The milling head 4 can approach the mechanical connector 5 and contact the weld foot 503 to facilitate milling the weld foot 503. The milling head 4 can be away from the mechanical connector 5 to facilitate separation of the guide member 3 from the mechanical connector 5 after the milling is completed.

[0056] See also Figure 2 In some embodiments of the present application, the milling machine body 1 includes a motor 101, a transmission assembly and a chuck 103. The transmission assembly includes a driving bevel gear and a driven bevel gear meshing with each other, the motor 101 is connected to the driving bevel gear, the driven bevel gear is connected to the chuck 103, and the driven bevel gear is a hollow structure.

[0057] Specifically, the rotating shaft of the motor 101 can be connected to the driving bevel gear through a key, and the rotating shaft of the motor 101 is arranged parallel to the rotating shaft of the driving bevel gear. The driving bevel gear and the driven bevel gear can be used to transmit motion and power between two intersecting axes, wherein the rotation axis of the driving bevel gear and the rotation axis of the driven bevel gear form an angle of 90°.

[0058] It should be noted that the motor 101 can drive the active bevel gear to rotate, and the active bevel gear drives the driven bevel gear to rotate. The driven bevel gear is connected to the chuck 103, and the driven bevel gear can drive the chuck 103 to rotate synchronously.

[0059] In some embodiments of the present application, the number of teeth of the active bevel gear is less than the number of teeth of the driven bevel gear, so that the transmission assembly can reduce the rotation speed of the motor 101 and increase the torque.

[0060] In some embodiments of the present application, a through hole is provided at the center position of the driven bevel gear, and the guide member 3 passes through the through hole of the driven bevel gear.

[0061] See also Figure 2-Figure 5 In some embodiments of the present application, the milling machine body 1 further includes a housing 102, a driving bevel gear and a driven bevel gear are installed in the housing 102, a chuck 103 is connected to the housing 102, and the housing 102 is connected to the adjusting member 2. For example, the outer housing of the motor 101 can be fixedly connected to the housing 102, and specifically, the outer housing of the motor 101 can be connected to the housing 102 by bolt connection or interference fit.

[0062] In some embodiments of the present application, one end of the chuck 103 facing the housing 102 can be rotatably connected to the housing 102 , and the chuck 103 and the housing 102 do not separate from each other in the length extension direction of the guide member 3 .

[0063] In some embodiments of the present application, when the driven bevel gear drives the chuck 103 to rotate synchronously, the chuck 103 can rotate around the housing 102. The housing 102 is rotatably connected to the adjusting member 2, and the housing 102 and the adjusting member 2 do not separate from each other in the length extension direction of the guide member 3.

[0064] It should be noted that the driving bevel gear and the driven bevel gear are located in the housing 102, and the housing 102 can protect the driving bevel gear and the driven bevel gear, isolate dust, and reduce or avoid contact between the driving bevel gear and the driven bevel gear and external dust.

[0065] See also Figure 2 and Figure 8 In some embodiments of the present application, the guide member 3 includes a middle section 301, a guide strip is provided on the outer wall of the middle section 301, an extension direction of the guide strip is parallel to the axial direction of the guide member 3, and a guide groove cooperating with the guide strip is provided on the milling machine body 1.

[0066] Specifically, the middle section 301 may be cylindrical. At least one guide bar is disposed on the outer wall surface of the middle section 301. When there are multiple guide bars, the multiple guide bars may be evenly distributed on the outer wall surface of the middle section 301 around the circumference.

[0067] A guide groove cooperating with the guide strip is arranged inside the housing 102 of the milling machine body 1. At least one guide groove is arranged. When there are multiple guide grooves, the multiple guide grooves correspond to the multiple guide strips one by one, and the multiple guide grooves are evenly distributed on the housing 102.

[0068] In some embodiments of the present application, the surface of the guide strip away from the outer wall of the middle section 301 can be a plane or an arc surface. When the surface of the guide strip away from the outer wall of the middle section 301 is an arc surface, the contact area between the guide strip and the guide groove can be reduced, thereby reducing the friction between the guide strip and the guide groove, so that the sliding between the guide member 3 and the milling machine body 1 is smoother.

[0069] In some embodiments of the present application, a guide groove is provided in the middle section 301 of the guide member 3, and a guide strip matching the guide groove is provided in the milling machine body 1.

[0070] For example, the number of guide bars and guide grooves may be two, three, four, five or six.

[0071] See also Figure 2 and Figure 8 In some embodiments of the present application, the guide member 3 includes a threaded section 302 connected to the middle section 301 , the adjusting member 2 is sleeved on the threaded section 302 , and the adjusting member 2 is threadedly connected to the threaded section 302 .

[0072] In some embodiments of the present application, the middle section 301 and the threaded section 302 can be fixedly connected by integral molding or welding. When the middle section 301 and the threaded section 302 are integrally molded, the production process can be simplified, the assembly time can be reduced, the production efficiency can be improved, and the integrity and durability of the guide member 3 can be enhanced.

[0073] In some embodiments of the present application, a threaded through hole is set at the center position of the adjusting member 2, and an external thread is set on the threaded segment 302. The threaded through hole of the adjusting member 2 is inserted into the external thread of the threaded segment 302 so that the adjusting member 2 is threadedly connected to the threaded segment 302, and the threaded connection between the adjusting member 2 and the threaded segment 302 is self-locking.

[0074] It should be noted that the adjusting member 2 can be rotated manually. The clockwise or counterclockwise rotation of the adjusting member 2 can drive the milling machine body 1 to slide along the length extension direction of the guide member 3. The milling machine body 1 can drive the milling head 4 to approach or move away from the mechanical connector 5, thereby realizing the adjustment of feed and retract as well as feed amount, so as to facilitate milling of the weld foot 503 of the mechanical connector 5.

[0075] See also Figure 2 In some embodiments of the present application, the milling head 4 includes a cutter disc 401, and one end of the cutter disc 401 facing the adjusting member 2 is connected to the chuck 103. When the chuck 103 rotates around the housing 102 driven by the driven bevel gear, the chuck 103 can drive the cutter disc 401 to rotate together.

[0076] In some embodiments of the present application, a cross protrusion is provided at one end of the cutter disc 401 facing the chuck 103, and a cross groove is provided at one end of the chuck 103 facing the cutter disc 401. The cross protrusion of the cutter disc 401 cooperates with the cross groove of the chuck 103 and is fixed by a fixing member. The fixing member may be a bolt or a screw. The cutter disc 401 is detachably connected to the chuck 103. When the cutter disc 401 needs to be replaced, the cutter disc 401 can be removed from the chuck 103.

[0077] Specifically, the cross protrusion of the cutter disc 401 is inserted into the cross groove of the chuck 103, and a bolt hole is set at the bottom of the cross groove. After the bolt is screwed into the bolt hole, the cross protrusion is squeezed to achieve a fixed connection between the cutter disc 401 and the chuck 103; the bolt is loosened so that it no longer squeezes the cross protrusion, and the cutter disc 401 can be removed. For example, the bolt hole can be a bolt hole with a diameter of 6 mm, the bolt can be a hexagon socket high-strength bolt, the number of bolts can be eight, and the four squeezed pieces of the cross protrusion are squeezed by two bolts respectively to achieve a fixed connection between the cutter disc 401 and the chuck 103.

[0078] See also Figure 2 , Figure 6-Figure 7In some embodiments of the present application, a through hole 404 is provided at the center of the cutter disc 401, and the through hole 404 of the cutter disc 401 penetrates the cutter disc 401 along the extension direction of the rotary axis of the cutter disc 401. The through hole 404 of the cutter disc 401 can be sleeved on the mechanical connector 5. The guide member 3 passes through the through hole 404 of the cutter disc 401 and is connected to the mechanical connector 5.

[0079] It should be noted that the cutter disc 401 is sleeved on the outside of the mechanical connector 5, and the cutter disc 401 has an automatic centering function, which can realize automatic centering of the cutter disc 401 and the mechanical connector 5, so that the positioning is fast during milling processing and the cutter disc 401 is stable.

[0080] In some embodiments of the present application, the diameter of the through hole 404 of the cutter head 401 is slightly larger than the outer diameter of the sleeve 501. During milling, the through hole 404 of the cutter head 401 can play a role in end fixing and guiding.

[0081] It should be noted that the through hole 404 of the cutter disc 401 is sleeved on the sleeve 501 of the mechanical connector 5, and the mechanical connector 5 is welded to the embedded part 6. The weld foot milling equipment can utilize the self-stabilizing processing of the embedded part 6. During processing, it is only necessary to insert the cutter disc 401 into the sleeve 501 of the mechanical connector 5 for processing. It has the advantages of simple processing, high efficiency, low cost and high flexibility.

[0082] See also Figure 2 and Figure 6 In some embodiments of the present application, a blade 403 is provided at one end of the cutter disc 401 away from the adjusting member 2, and the blade 403 is connected to the cutter disc 401 through a connecting member 402. Specifically, a blade mounting area can be provided on the cutter disc 401, and the blade 403 can be mounted on the blade mounting area through the connecting member 402, so that the milling process of the welding foot 503 of the mechanical connecting member 5 with a specific size can be realized. It should be noted that the connecting member 402 can be a screw or a bolt, etc.

[0083] In some embodiments of the present application, the connection between the blade 403 and the cutter head 401 can be detachable, which is convenient for replacing the blade 403. When the blade 403 is damaged, it is not necessary to replace the entire milling head 4, but only the blade 403, which reduces costs.

[0084] See also Figure 2 and Figure 4-Figure 6 In some embodiments of the present application, multiple blades 403 are evenly distributed around the circumference. Multiple blades 403 evenly distributed around the circumference can improve the balance of the milling head 4 during milling and improve the milling quality. The number of blades 403 should not be too many or too few. For example, the number of blades 403 can be three or four. The number of blades 403 can be adjusted according to the cutting material, processing speed, etc., and the shape of the blades 403 can be adjusted according to the milling structure.

[0085] It should be noted that when the number of blades 403 is too large, there are more connection points on the cutter head 401, which reduces the overall strength of the milling head 4; when the number of blades 403 is too small, the weld feet 503 of the mechanical connector 5 cannot be fully milled.

[0086] It should be noted that a special cutter head 401 and a blade 403 can be customized according to the size of the weld foot 503 of the mechanical connector 5 .

[0087] See also Figure 2 and Figure 8 In some embodiments of the present application, the guide member 3 includes a conical section 303 connected to the middle section 301 , and the conical section 303 is located at one end of the middle section 301 away from the threaded section 302 .

[0088] In some embodiments of the present application, the middle section 301 and the conical section 303 can be fixedly connected by integral molding or welding. When the middle section 301 and the conical section 303 are integrally molded, the production process can be simplified, the assembly time can be reduced, the production efficiency can be improved, and the integrity and durability of the guide member 3 can be enhanced.

[0089] In some embodiments of the present application, the end of the conical segment 303 close to the middle segment 301 is the first end of the conical segment 303, the end of the conical segment 303 away from the middle segment 301 is the second end of the conical segment 303, and the diameter of the first end of the conical segment 303 is greater than the diameter of the second end of the conical segment 303. The outer wall surface of the conical segment 303 is provided with a conical thread, and the conical thread of the conical segment 303 is connected to the conical threaded hole 502 of the mechanical connector 5.

[0090] The conical section 303 of the guide member 3 is connected to the conical threaded hole 502 of the mechanical connector 5, and the through hole 404 of the cutter disc 401 is sleeved on the mechanical connector 5, that is, the weld leg milling and cutting equipment and the mechanical connector 5 are connected by threads and cooperated through positioning holes, making the assembly and disassembly of the weld leg milling and cutting equipment and the mechanical connector 5 more convenient and less costly.

[0091] It should be noted that the guide member 3 sequentially passes through the milling machine body 1 and the milling head 4 and is connected to the mechanical connector 5. The guide member 3 connects the milling machine body 1 and the milling head 4 and the mechanical connector 5 in series, which has a simple structure, easy operation and high reliability.

[0092] See also Figure 2-Figure 5 In some embodiments of the present application, the outer wall surface of the adjusting member 2 is evenly distributed with handles 7. Specifically, the handles 7 are fixedly mounted on the outer wall surface of the adjusting member 2. Specifically, the handles 7 can be fixed to the outer wall surface of the adjusting member 2 by welding or screw connection.

[0093] It should be noted that when the handle 7 is fixed to the outer wall of the adjusting member 2 by welding, the connection strength between the outer wall of the adjusting member 2 and the handle 7 is high, and the handle 7 is not easy to fall off from the outer wall of the adjusting member 2. When the handle 7 is fixed to the outer wall of the adjusting member 2 by screws, the handle 7 and the adjusting member 2 are detachable. When the handle 7 is damaged, the handle 7 can be replaced alone without replacing the adjusting member 2, which saves costs.

[0094] In some embodiments of the present application, the rotation of the adjusting member 2 may also be achieved by other means. For example, the adjusting member 2 may be driven to rotate by an electric motor.

[0095] See also Figure 2 and Figure 8 In some embodiments of the present application, the guide member 3 further includes a stopper 304, which is connected to the end of the threaded segment 302 away from the middle segment 301. The stopper 304 is used to limit the travel of the adjusting member 2 on the threaded segment 302, so that the adjusting member 2 is not easily separated from the end of the threaded segment 302 away from the middle segment 301.

[0096] In some embodiments of the present application, the stopper 304 can be fixed to the threaded segment 302 by welding or integral molding. The connection strength between the stopper 304 and the threaded segment 302 is high, so that the stopper 304 and the threaded segment 302 are not easy to separate.

[0097] In some embodiments of the present application, the stopper 304 can be detachably connected to the threaded segment 302. For example, the stopper 304 is provided with a threaded hole on the end surface facing the threaded segment 302, and the threaded hole of the stopper 304 is threadedly connected to the threaded segment 302.

[0098] In some embodiments of the present application, the maximum diameter of the stopper 304 is greater than the maximum diameter of the threaded segment 302, so that the adjusting member 2 is blocked by the stopper 304 and is not easily separated from the end of the threaded segment 302 away from the middle segment 301. If the maximum diameter of the stopper 304 is less than or equal to the maximum diameter of the threaded segment 302, the adjusting member 2 is not blocked by the stopper 304 and is easily separated from the end of the threaded segment 302 away from the middle segment 301.

[0099] In some embodiments of the present application, the maximum diameter of the stopper 304 is smaller than the outer diameter of the adjusting member 2, so that the guide member 3 is not easy to affect the manual operating handle 7. If the maximum diameter of the stopper 304 is greater than or equal to the outer diameter of the adjusting member 2, the manual operating handle 7 will be affected due to the excessive size of the stopper 304.

[0100] Before use, first fix the blade 403 on the cutter disc 401 through the connecting piece 402, then connect the milling head 4 to the chuck 103, and then insert the guide piece 3 from the lower center of the milling head 4, and connect the upper part of the guide piece 3 to the adjusting piece 2 to complete the cutting preparation.

[0101] When in use, the milling head 4 is sleeved on the sleeve 501 of the mechanical connector 5. The guide member 3 passes through the center of the cutter head 401, and the tapered thread of the guide member 3 is threadedly connected with the tapered threaded hole 502 of the mechanical connector 5. At this time, the cutter head 401 and the guide member 3 play a dual fixed centering role. The adjusting member 2 is rotated, and the adjusting member 2 drives the milling body 1 and the milling head 4 to move up and down along the guide member 3. The motor 101 of the milling body 1 transmits power to the chuck 103 through the transmission assembly, and then transmits it to the milling head 4, so as to realize the milling of the weld foot 503 of the mechanical connector 5.
