Description

Technical Field

[0001] This utility model relates to the technical field of hinge processing, and in particular to a fusion mechanism for a hinge assembly machine. Background Technology

[0002] Hinges are used to install on two relatively independent objects, such as windows and window frames, doors and door frames. Hinges utilize the principle of their relative rotation to allow two relatively independent objects to rotate around an axis between open and closed states. In the assembly process of automated hinge production, hinge assembly machines are used to assemble hinge parts to form a complete hinge. During the hinge assembly process, the hinge assembly machine needs to position each component before assembling it, so that each station assembles according to the preset position, realizing the assembly of each hinge part into a whole. In existing hinge assembly machines, such as patent application number 202510075574.3, an assembly device for a hinge inner strip assembly is described, including a torsion spring feeding station, a pin insertion station, a torsion spring feeding mechanism, and a pin insertion mechanism. Both the torsion spring feeding station and the pin insertion station are located on a rotating disk. The torsion spring feeding mechanism feeds the torsion spring at the torsion spring feeding station and assembles the torsion spring into a preset position. The pin insertion mechanism feeds the pin at the pin insertion station and assembles the pin into a preset position. (See the accompanying drawings for details.) It is known that the torsion spring feeding and nail insertion processes are carried out at two separate workstations. That is, two workstations need to be set up on the turntable for the torsion spring feeding workstation and the nail insertion workstation. Both torsion spring feeding and nail insertion are two necessary processes in hinge assembly. Completing the two processes through two workstations is the usual design. However, this will cause the turntable to need to reserve two workstations for the two processes, and will also cause the overall structure of the hinge assembly machine to be less compact, resulting in a large space occupation of the hinge assembly machine. Therefore, this utility model provides a solution that can reduce the number of workstations in the hinge assembly machine. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fusion mechanism for a hinge assembly machine.

[0004] To achieve the above objectives, this utility model discloses a fusion mechanism for a hinge assembly machine, including a base, a rotating disk rotatably connected to the top surface of the base, and a first fusion mechanism assembled with the base. The rotating disk has a first fusion station corresponding to the first fusion mechanism. The first fusion mechanism has a clamping position and an assembly position. The first fusion mechanism includes a through rod, a first gripper, and a second gripper. The first gripper clamps a connector from the clamping position to the assembly position. A torsion spring is placed at the assembly position. The through rod outputs a connecting rod towards the torsion spring and the connector. The connecting rod passes between the hinge hole of the torsion spring and the hinge hole of the connector to form an assembly. The second gripper includes a first gripping finger and a second gripping finger. The first gripping finger and the second gripping finger approach each other to clamp the connector, thereby clamping the assembly from the assembly position to the first fusion station.

[0005] The first fusion mechanism is provided with a push position and includes a push block. The material of the torsion spring is placed in the push position, and the push block pushes the torsion spring from the push position to the assembly position in preparation for installation with the torsion spring and the connecting rod to form the assembly.

[0006] The first fusion mechanism includes a top block with a clamping groove. The side of the clamping groove extends through the top surface of the top block. The clamping position is located in the clamping groove, and the opening of the clamping groove faces the material direction of the connector. After the connector is placed in the clamping groove, one end of the connector is exposed outside the clamping groove so that the first gripper can clamp the connector to the assembly position.

[0007] The first fusion mechanism includes a receiving component, the top surface of which is provided with a groove, the push position is located at the opening of the groove, the opening of which faces the material direction of the torsion spring, and the assembly position is located at the end of the groove.

[0008] The receiving component has an assembly hole, the axis of which is coaxial with the axis of the hinge hole of the torsion spring and the hinge hole of the connecting component at the assembly position. The assembly hole extends from the side wall of the receiving component to the slide groove. The through rod is slidably connected to the assembly hole. After the connecting component moves to the assembly position, the through rod outputs the connecting rod through the assembly hole toward the hinge hole of the torsion spring and the hinge hole of the connecting component to form the assembly.

[0009] The second gripper includes an arc groove component. The bottom surface of the arc groove component has an arc-shaped groove that is adapted to the arc arm portion of the torsion spring. The top surface of the arc groove component has a protruding limiting portion. The side of the limiting portion is tangent to the groove surface of the arc-shaped groove. When the second gripper clamps the assembly, the arc arm portion of the torsion spring is placed in the arc-shaped groove, and the bottom surface of the limiting portion abuts against the straight arm portion of the torsion spring.

[0010] The arc groove component has a relief groove, which is a through groove that extends through the arc groove. The axial included angle of the relief groove and the arc groove is equal to the axial included angle of the connector and the torsion spring. The end of the connector passes through the relief groove. The first clamping finger and the second clamping finger clamp the end of the connector so that the second clamping claw can clamp the connector.

[0011] The second gripper includes a positioning element located outside the relief groove. The first gripper finger and the second gripper finger are located outside the relief groove. When the second gripper grips the assembly, the bottom surface of the positioning element abuts against the top surface of the end of the connector.

[0012] The first fusion mechanism includes a pin-through assembly, which includes a guide pin, a pin-driving component, and a clamp. The pin-driving component outputs a connecting pin. The clamp holds the pin-driving component and moves it toward the first fusion station. The guide pin moves toward the first fusion station. The pin-driving component and the guide pin move toward the first fusion station. The pin-driving component outputs a first connecting pin. The guide pin guides the first connecting pin to move and brings out the rod-through component to install the first connecting pin on the arm body seat, so that the connecting component and the torsion spring are hinged to the arm body seat.

[0013] The first fusion mechanism includes a first slide for inputting materials, the first slide is directed toward the clamping position to input the connector, and the output port of the first slide is connected to the clamping position.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the torsion spring is placed in the assembly position, the first gripper drives the connector from the clamping position to the assembly position, and the through rod outputs the connecting rod towards the hinge hole of the torsion spring and the hinge hole of the connector, so that the connecting rod is inserted between the hinge hole of the torsion spring and the hinge hole of the connector to complete the assembly of the torsion spring and the connector, thereby forming an assembly. The second gripper then drives the assembled torsion spring and connector from the assembly position to the first fusion position. After the second gripper clamps the connector, it moves upward. The connector abuts against the connecting rod to drive the connecting rod to move upward. The connecting rod abuts against the torsion spring to drive the torsion spring to move upward. The above are the processes of installing the connector onto the arm base and installing the torsion spring onto the arm base. The nailing component and the guide pin component work together to install the first connecting nail output by the chuck onto the arm body seat, so that the connecting component and the torsion spring are hinged to the arm body seat, thereby completing the hinged connection of the connecting component and the torsion spring into the arm body seat. The above is the nailing process between the connecting component, the torsion spring and the arm body seat. With the above setup, the processes of installing the connector to the boom seat, installing the torsion spring to the boom seat, and threading the connector, torsion spring, and boom seat through the bolts are all integrated into the first fusion station for assembly, improving the compactness of the hinge assembly machine and reducing the space occupied by the hinge assembly machine.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will be combined with... Figure 1-17 The accompanying drawings provide a further detailed description of this utility model.

[0018] This utility model relates to the assembly of hinged arm components, such as... Figure 3 As shown, a hinge arm assembly is mounted on the fixture 98. The hinge arm assembly includes an arm base 91, a torsion spring 92, a connector 93, a rocker arm 94, a first connecting pin 95, and a second connecting pin 96. The torsion spring 92 is sleeved on the outside of the first connecting pin 95, and the connector 93 is also sleeved on the outside of the first connecting pin 95. The connector 93 is located in the middle of the first connecting pin 95, that is, the connector 93 rotates around the first connecting pin 95. The rocker arm 94 is sleeved on the outside of the second connecting pin 96, that is, the rocker arm 94 rotates around the second connecting pin 96. The first connecting pin 95 and the second connecting pin 96 are then riveted to the arm base 91, thereby completing the assembly of the hinge arm assembly.

[0019] This utility model provides a fusion mechanism for a hinge assembly machine adapted to the automated assembly of the aforementioned hinge arm assembly. The mechanism includes a base 991, a rotating disk 992, an arm support loading mechanism 1, a first fusion mechanism 2, a connector oiling mechanism 3, a second fusion mechanism 4, a first riveting mechanism 5, a second riveting mechanism 6, a rocker arm oiling mechanism 7, and a discharge mechanism 8. The rotating disk 992 is rotatably connected to the top surface of the base 991. Along its circumference, the rotating disk 992 is sequentially equipped with an arm support loading station, a first fusion station 205, a connector oiling station, a second fusion station, a first riveting station, a second riveting station, a rocker arm oiling station, and a discharge station. Each of these stations is equipped with a suitable fixture. 98. The boom seat loading mechanism 1 is assembled on the base 991 and corresponds to the boom seat loading station. The first fusion mechanism 2 is assembled on the base 991 and corresponds to the first fusion station 205.

The rocker arm oiling mechanism 7 is assembled on the base 991 and corresponds to the rocker arm 94 oiling station. The discharge mechanism 8 is assembled on the base 991 and corresponds to the discharge station.

[0020] This utility model improves the first fusion mechanism 2, which is used to assemble the connector 93 and the torsion spring 92 to the arm base 91. The rotating disk 992 is rotatably connected to the top surface of the base 991 and is driven to rotate by a motor installed on the base 991. The first fusion mechanism 2 is assembled with the base 991. The rotating disk 992 has a first fusion station 205 corresponding to the first fusion mechanism 2. The first fusion station 205 is located on the top surface of the rotating disk 992 and is close to the outer periphery. The first fusion mechanism 2 has a clamping position 201 for clamping the connector 93 to be assembled and an assembly position 203 for assembling the connector 93 and the torsion spring 92. The first fusion mechanism 2 includes a through rod 204, a first gripper 21 for clamping the connector 93 and driving the connector 93 from the clamping position 201 to the assembly position 203, and a gripper 21 for clamping the assembled torsion spring 92 and the connector 93 and driving them from the assembly position 203 to the first fusion position 203. The second gripper 22 of the assembly station 205 moves back and forth between the clamping position 201 and the assembly position 203. The connecting rod 97 is output from the through rod 204 towards the hinge hole of the torsion spring 92 and the hinge hole of the connector 93, so that the connecting rod 97 is inserted between the hinge hole of the torsion spring 92 and the hinge hole of the connector 93 to complete the assembly of the torsion spring 92 and the connector 93, thereby forming the assembly 931. The second gripper 22 then moves the assembled torsion spring 92 and connector 93 from... Assembly station 203 is driven to first fusion station 205. After the second gripper 22 clamps the connector 93, it moves upward. The connector 93 abuts against the connecting rod 97 to drive the connecting rod 97 to move upward. The connecting rod 97 abuts against the torsion spring 92 to drive the torsion spring 92 to move upward. That is, the second gripper 22 moves back and forth between assembly station 203 and first fusion station 205. The above are the processes of installing the connector 93 onto the arm base 91 and the torsion spring 92 onto the arm base 91.

[0021] The first fusion mechanism 2 also includes a pin-insertion assembly 23, which includes a pin guide 231, a pin-driving component 234, a pin-insertion cylinder 235, and a clamp 233. The pin-insertion cylinder 235 is mounted on the base 991 and drives the pin guide 231 to move toward the hinge hole of the connector 93, the torsion spring 92, and the arm base 91. The clamp 233 is provided with an input pin hole 236 for outputting the first connecting pin 95. The clamp 233 clamps and connects the pin-driving component 234. The pin-driving component 234 is provided with an output pin hole for outputting the first connecting pin 95 toward the hinge hole. The clamp 233 is driven by the cylinder, and the clamp 233 drives the pin-driving component 234 to move toward the first fusion station 205. At the same time, the output pin hole of the pin-driving component 234 is aligned with the hinge hole of the arm base 91, and the first connecting pin 95 is output. That is, the pin-driving component 234 outputs the first connecting pin 95 to the connector 93 and the torsion spring 92 mounted on the arm base 91. When the first connecting pin 95 is connected, the pin-passing cylinder 235 drives the guide pin 231 to move toward the hinge hole. The guide pin 231 extends into the hinge hole, guiding the through rod 204 of the assembly out of the hinge hole and disengaging it from the arm seat 91. At the same time, it cooperates with the nail-driving component 234 to guide the first connecting pin 95 through the hinge hole, hinge the connecting component 93, the torsion spring 92, and the arm seat 91. Through the above arrangement, the nail-driving component 234 and the guide pin 231 cooperate. The first connecting nail 95 output from the nailing component 234 is installed on the arm body seat 91, so that the connecting component 93 and the torsion spring 92 are hinged to the arm body seat 91, thereby completing the hinged connection of the connecting component 93 and the torsion spring 92 into the arm body seat 91. The above is the nailing process between the connecting component 93, the torsion spring 92 and the arm body seat 91. The cooperation between the nailing component 234 and the guide pin component 231 to connect the first connecting nail 95 to the arm body seat 91 is the prior art, and will not be described in detail here.

[0022] The connector 93 is placed on the clamping position 201. After the torsion spring 92 is driven to the assembly position 203, the first gripper 21 clamps the connector 93 on the clamping position 201 and clamps the connector 93 onto the assembly position 203. At the same time, the hinge hole of the connector 93 is aligned with the hinge hole of the torsion spring 92. The through rod 204 then outputs the connecting rod 97 towards the connector 93 and the torsion spring 92, so that the connecting rod 97 is located between the hinge hole of the connector 93 and the hinge hole of the torsion spring 92. Thus, the connector 93 and the torsion spring 92 form an assembly 931 to complete the assembly of the connector 93 and the torsion spring 92. The second gripper 22 then clamps the assembled connector 93 and the torsion spring 92 to the first fusion station 205, and then installs the assembled connector 93 and the torsion spring 92 onto the arm body seat 91.

[0023] With the above settings, the processes of installing the connector 93 onto the armrest 91, installing the torsion spring 92 onto the armrest 91, and threading the connector 93, torsion spring 92, and armrest 91 through the nail are all integrated into the first fusion station 205 for assembly, thereby improving the compactness of the hinge assembly machine and reducing the space occupied by the hinge assembly machine.

[0024] The first fusion mechanism 2 is provided with a push position 202 and includes a push block 273. The push block 273 moves back and forth between the push position 202 and the assembly position 203. The push block 273 pushes the torsion spring 92 to be assembled toward the assembly position 203. Through the above settings, the automation level of driving the torsion spring 92 is improved.

[0025] The first fusion mechanism 2 includes a first slide 241 for inputting a connector 93 toward the clamping position 201. The input port of the first slide 241 is connected to the first vibratory plate 242, and the output port of the first slide 241 is connected to the clamping position 201. The first vibratory plate 242 is used to feed the connector 93, and the first slide 241 is used to transfer the connector 93 from the first vibratory plate 242 to the clamping position 201.

[0026] The first fusion mechanism 2 includes a second slide 243 for inputting a torsion spring 92 toward the push position 202. The input port of the second slide 243 is connected to the second vibratory plate 244, and the output port of the second slide 243 is connected to the push position 202. The second vibratory plate 244 is used to feed the torsion spring 92 to be assembled, and the second slide 243 is used to transfer the torsion spring 92 from the second vibratory plate 244 to the push position 202.

[0027] The first fusion mechanism 2 includes a top block 25, which is vertically driven by a lifting cylinder 252 to achieve vertical reciprocating motion. The top block 25 has a clamping slot 251, the opening of which faces the output port of the first slide rail 241, and the clamping slot 251 extends through the top surface of the top block 25. The clamping position 201 is located in the clamping slot 251. The connecting member 93 slides into the clamping slot 251 through the first slide rail 241, that is, into the clamping position 201, and part of the connecting member 93 is exposed outside the clamping slot 251. The first gripper 21 clamps the connector 93 on one side of the second slide 243 facing downwards. After the connector 93 enters the clamping slot 251 through the first slide 241, the lifting cylinder 252 drives the top block 25 to move upwards, so that the connector 93 also moves upwards. The first gripper 21 then clamps the exposed part of the connector 93. At the same time, the lifting cylinder 252 drives the top block 25 to reset downwards to make room for the first gripper 21. The first gripper 21 then clamps the connector 93 and moves it toward the assembly position 203 to place the connector 93 into the assembly position 203.

[0028] The first fusion mechanism 2 includes a receiving member 27, the top surface of which is provided with a groove 271. The output port of the second slide 243 is connected to the groove opening 2712 of the groove 271. The push position 202 is located on the receiving member 27 and at the groove opening 2712. The push block 273 slides back and forth between the groove opening 2712 and the end of the groove 2713. The assembly position 203 is located at the end of the groove 271. The push cylinder 272 drives the push block 273 to slide back and forth between the push position 202 and the assembly position 203, so that the push block 273 drives the torsion spring 92 from the push position 202 to the assembly position 203.

[0029] The receiving part 27 has an assembly hole. The axis of the assembly hole is coaxial with the axis of the torsion spring 92 and the hinge hole of the connector 93 on the assembly position 203. The assembly hole extends from the receiving part 27 to the slide groove 271. The through rod 204 slides back and forth through the assembly hole. The through rod cylinder 206 drives the through rod 204 to pass through the assembly hole and output the connecting rod 97 to the torsion spring 92 and the connector 93 on the assembly position 203, so as to complete the connection between the torsion spring 92 and the connector 93, that is, the torsion spring 92 and the connector 93 form the assembly part 931.

[0030] This utility model includes a linear motor 229, a second gripper 22 connected to a slide of the linear motor 229, and a slide rail of the linear motor 229 connected to a mounting plate 228. The linear motor 229 includes a horizontal linear motor and a vertical linear motor to drive the second gripper 22 to move horizontally and vertically.

[0031] The second gripper 22 includes a first gripper finger 221, a second gripper finger 222, and an arcuate groove 223. The first gripper finger 221 and the second gripper finger 222 clamp the connecting member 93 close to each other. The arcuate groove 223 is located between the first gripper finger 221 and the second gripper finger 222. The arcuate groove 223 has an arcuate groove 224 that matches the arcuate arm portion 923 of the torsion spring 92. The arcuate groove 224 is located on the bottom surface of the arcuate groove 223. A limiting portion 225 protrudes from the top surface of the arcuate groove 223. The side of the limiting portion 225 is tangent to the groove surface of the arcuate groove 224, and the bottom surface of the limiting portion 225 abuts against the straight arm portion of the torsion spring 92. After the first gripper finger 221 and the second gripper finger 222 clamp the connecting member 93, the torsion spring 92... The arc arm portion 923 is located in the arc groove 224. The arc arm portion 923 of the torsion spring 92 matches the arc groove 224. At the same time, since the weight of the U-shaped portion 921 of the torsion spring 92 is greater than that of the two straight arms 922 of the torsion spring 92, the U-shaped portion 921 of the torsion spring 92 will rotate downward under the action of gravity, and the two straight arms 922 of the torsion spring 92 will rotate upward. After the first clamping finger 221 and the second clamping finger 222 clamp the connector 93, the limiting portion 225 abuts against the straight arm portion 922 of the torsion spring 92, which can prevent the straight arm portion 922 of the torsion spring 92 from rotating upward, thus preventing the risk of misalignment of the torsion spring 92 due to rotation, so that the torsion spring 92 and the connector 93 are installed in the arm seat 91 according to the preset position.

[0032] The arc groove 223 has a relief groove 227, which is a through groove that extends to the arc groove 224. When the second gripper 22 clamps the connector 93, one end of the connector 93 passes through the relief groove 227 so that the first gripper finger 221 and the second gripper finger 222 clamp the connector 93 to improve the matching degree between the connector 93 and the preset position.

[0033] The second gripper 22 also includes a positioning element 226, which is located outside the first gripper finger 221 and the second gripper finger 222. The bottom surface of the positioning element 226 abuts against one end of the connector 93. When the first gripper finger 221 and the second gripper finger 222 grip the connector 93, one end of the connector 93 abuts against the bottom surface of the positioning element 226, further improving the matching degree between the connector 93 and the preset position.

[0034] The positioning member 226 has a receiving groove 2261 on the side facing the connector 93. The receiving groove 2261 extends to the bottom surface of the positioning member 226, and one end of the connector 93 is located in the receiving groove 2261 to further limit the position of the connector 93.

[0035] Torsion spring 92 is a double torsion spring, and connector 93 is located between the two sub-torsion springs.

[0036] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They cannot be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit of the main technical solution of this utility model should be covered within the protection scope of this utility model.
