Description

Technical Field

[0001] This utility model relates to the technical field of mill-turn couplings, and in particular to a mill-turn coupling. Background Technology

[0002] The twin-spindle twin-turret milling and turning machine tool is a high-performance, high-precision composite machining equipment. In the twin-spindle twin-turret milling and turning machine tool, a coupling needs to be installed at the connection between the motor and the lead screw. The coupling acts as an "error compensator" and a "torque transmitter" between the motor and the lead screw, which can ensure the transmission accuracy and stability of the twin-spindle twin-turret milling and turning machine tool.

[0003] Flange couplings are commonly used rigid couplings. They consist of two flanged half-couplings, which are then assembled into one unit using multiple sets of bolts. Disassembling and assembling flange couplings requires the use of tools such as wrenches and the sequential tightening of multiple sets of bolts and nuts, making the process cumbersome and inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a milling and turning coupling to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A milling and turning coupling is installed between a motor and a lead screw in a milling and turning machine. The coupling body consists of a first half-coupling, a second half-coupling, and an intermediate washer. The outer side wall of the first half-coupling has a first threaded groove, the outer side wall of the second half-coupling has a second threaded groove, and the outer side wall of the intermediate washer has a third threaded groove.

[0007] The mounting assembly, which is mounted on the coupling body, is used to connect and secure the first half-coupling, the second half-coupling, and the intermediate washer.

[0008] Preferably, the first half-coupling and the second half-coupling each have multiple sets of positioning grooves and rod holes on the side that is close to each other.

[0009] Preferably, the intermediate washer has several positioning rings, which are respectively embedded in the positioning grooves of the first half coupling and the second half coupling, and each of the positioning rings of the intermediate washer has a ring opening.

[0010] Preferably, the mounting components include:

[0011] The internally threaded cylinder has its threads installed on the first threaded groove on the outer wall of the first half-coupling, the second threaded groove on the outer wall of the second half-coupling, and the third threaded groove on the intermediate washer. One side of its inner wall has a rotating groove.

[0012] A swivel ring, which is rotatably installed in a groove on one side of the inner wall of the internally threaded cylinder;

[0013] Several positioning rods are fixedly installed on one side of the rotating ring, and their other ends pass through multiple sets of positioning grooves and rod holes on the first half coupling and the second half coupling, as well as multiple ring openings on the intermediate washer.

[0014] Preferably, the cross-section of the rotating groove on the internal threaded cylinder is L-shaped, and the rotating ring is adapted to the rotating groove.

[0015] Preferably, the outer wall of the internally threaded cylinder has several flanges, which are distributed in a circumferential array.

[0016] Preferably, both the first half-coupling and the second half-coupling of the coupling body have an end, and both the first half-coupling and the second half-coupling have mounting holes on their ends.

[0017] In this application, when the installer screws the internal threaded cylinder to the left, several positioning rods on one side of the swivel pass through multiple sets of positioning grooves and rod holes on the first and second half couplings and multiple ring openings on the intermediate washer. At the same time, the internal threaded cylinder is threaded onto the first threaded groove on the outer wall of the first half coupling, the second threaded groove on the outer wall of the second half coupling, and the third threaded groove of the intermediate washer, thus achieving the connection and fixation between the first half coupling, the second half coupling, and the intermediate washer. This avoids the need to use wrenches or other auxiliary tools to tighten multiple sets of bolts and nuts. The disassembly method of the coupling body in this application can achieve the disassembly or installation of the first half coupling, the second half coupling, and the intermediate washer simply by screwing the internal threaded cylinder, making the operation simple and quick.

[0025] Traditional flanged couplings consist of two flanged half-couplings, which are then assembled into a single unit using multiple sets of bolts. Disassembly and assembly of these couplings requires tools such as wrenches and the sequential tightening of multiple sets of bolts and nuts, making the process cumbersome and inconvenient. To address these issues, this embodiment discloses a coupling for milling and turning operations, installed between the motor and the lead screw on a milling and turning machine. Figure 5 As shown; including: such as Figure 4 The coupling body 100 and mounting assembly 200 are shown.

The first half coupling 110 and the second half coupling 120 each have multiple sets of positioning grooves 1001 and rod holes 1002 on their respective sides. The intermediate washer 130 has several positioning rings 1302, which are respectively embedded in the positioning grooves 1001 of the first half coupling 110 and the second half coupling 120. Each of the positioning rings 1302 of the intermediate washer 130 has a ring opening 1303.

[0027] Continue as Figure 4As shown, in order to connect and install the first half-coupling 110, the second half-coupling 120, and the intermediate washer 130 of the coupling body 100, the outer side wall of the first half-coupling 110 has a first threaded groove 1101, the outer side wall of the second half-coupling 120 has a second threaded groove 1201, and the outer side wall of the intermediate washer 130 has a third threaded groove 1301; the mounting assembly 200 is disposed on the coupling body 100, and the mounting assembly 200 is used to connect and fix the first half-coupling 110, the second half-coupling 120, and the intermediate washer 130.

[0028] The mounting assembly 200 includes: an internally threaded cylinder 210, a swivel ring 220, and several positioning rods 230; the internally threaded cylinder 210 is threadedly mounted on the first threaded groove 1101 on the outer wall of the first half-coupling 110, the second threaded groove 1201 on the outer wall of the second half-coupling 120, and the third threaded groove 1301 of the intermediate washer 130, and has a swivel groove 2101 on one side of its inner wall, the swivel groove 2101 having an L-shaped cross-section; the swivel ring 220 is rotatably mounted in the swivel groove 2101 on one side of the inner wall of the internally threaded cylinder 210, and the swivel ring 220 is adapted to the swivel groove 2101; several positioning rods 230 are fixedly mounted on one side of the swivel ring 220, and their other ends pass through multiple sets of... The positioning groove 1001, rod hole 1002, and multiple annular openings 1303 on the intermediate washer 130 are all located within the positioning groove 1001, rod hole 1002, and multiple annular openings 1303 on the intermediate washer 130. When the internal threaded cylinder 210 is turned counterclockwise, several positioning rods 230 on one side of the rotating ring 220 pass through multiple sets of positioning grooves 1001, rod hole 1002, and multiple annular openings 1303 on the intermediate washer 130 on the first half coupling 110 and the second half coupling 120, respectively. At the same time, the internal threaded cylinder 210 is threaded onto the first threaded groove 1101 on the outer wall of the first half coupling 110, the second threaded groove 1201 on the outer wall of the second half coupling 120, and the third threaded groove 1301 on the intermediate washer 130, thereby achieving the connection and fixation between the first half coupling 110, the second half coupling 120, and the intermediate washer 130.

[0029] like Figure 1 As shown, the outer wall of the internally threaded cylinder 210 has several flanges 2102, which are arranged in a circumferential array; this allows the installer to hold the internally threaded cylinder 210 and adjust its rotation.

[0030] like Figure 3As shown, both the first half-coupling 110 and the second half-coupling 120 of the coupling body 100 have ends, and both ends of the first half-coupling 110 and the second half-coupling 120 have mounting holes 1003. When the output shaft of the motor extends into the round opening of the first half-coupling 110, the output shaft of the motor has a threaded hole, and a bolt is used to pass through the mounting hole 1003 on the end of the first half-coupling 110 and threaded into the threaded hole of the motor output shaft, thereby connecting the output shaft of the motor to the first half-coupling 110. When one end of the lead screw extends into the round opening of the second half-coupling 120, the lead screw has a threaded hole, and a bolt is used to pass through the mounting hole 1003 on the end of the second half-coupling 120 and threaded into the threaded hole of the lead screw, thereby connecting the lead screw to the second half-coupling 120. When the turning-milling compound motor is driven, torque is transmitted through the coupling body 100.

[0031] In this application, when the installer turns the internal threaded cylinder 210 counterclockwise, several positioning rods 230 on one side of the rotating ring 220 pass through multiple sets of positioning grooves 1001 and rod holes 1002 on the first half-coupling 110 and the second half-coupling 120, and multiple annular openings 1303 on the intermediate washer 130, respectively. Simultaneously, the internal threaded cylinder 210 is threaded into the first threaded groove 1101 on the outer wall of the first half-coupling 110 and the second threaded groove 120 on the outer wall of the second half-coupling 120. The first half-coupling 110, the second half-coupling 120, and the intermediate washer 130 are connected and fixed on the third threaded groove 1301 of the intermediate washer 130, avoiding the need to use wrenches or other auxiliary tools to tighten multiple sets of bolts and nuts. The disassembly method of the coupling body 100 in this application can be achieved by screwing the internal threaded cylinder 210 to disassemble or install the first half-coupling 110, the second half-coupling 120, and the intermediate washer 130, which is simple and quick to operate.
