Description

Technical Field

[0001] The invention relates to the field of assembly equipment, in particular to an assembly equipment for a corrugated pipe set. Background Art

[0002] Both ends of the bellows need to be assembled with components such as hexagonal nuts, steel sleeves, conical nuts and plastic retaining rings. If manual assembly is used, the efficiency is too low. There are currently related automated assembly equipment, but the assembly action requirements of the aforementioned components are different. For example, hexagonal nuts, steel sleeves and conical nuts can be directly put on, but plastic retaining rings need to be rotated and fixed on. Therefore, the existing equipment is either very complicated or can only assemble single components. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a bellows kit assembly device, by which the components of the bellows are assembled in multiple steps and positions, and the overall assembly process is smoother and more efficient.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a bellows kit assembly device includes a turntable, a positioning device, a frame, a feeding device and a loading device;

[0005] A plurality of the positioning devices are distributed in a circle on the turntable;

[0006] The frame corresponds to a part or all of the positioning devices provided with the feeding device;

[0007] The frame is provided with a loading device, and the loading device is arranged in a one-to-one correspondence with the feeding device.

[0008] When assembling the present solution, the end of the bellows is fixed to the positioning device, the object is taken out from the feeding device through the loading assembly, and then the object is placed at the end of the bellows and assembled in the loading assembly.

[0009] A feeding device provides a component supply, and multiple feeding devices and charging devices are used to assemble the components at the end of the bellows in steps. After the previous component of the bellows is assembled, the turntable drives the bellows to rotate to the next feeding device and charging device to assemble the next component.

[0010] By assembling the components of the bellows in multiple steps and positions, the overall assembly process becomes smoother and more efficient.

[0011] Preferably, the positioning devices are divided into several groups, and the positioning devices in the same group are respectively arranged corresponding to the two ends of the corrugated pipe. Assembling the two ends of the corrugated pipe at the same time can significantly improve the assembly efficiency.

[0012] Preferably, the turntable is rotatably matched with the frame, and the turntable is driven by a first motor. The first motor can more conveniently drive the turntable to rotate step by step, and the corrugated pipe is rotated and transported according to the workstation.

[0013] Preferably, the positioning device comprises a push block, a clamping arm and a reset rod;

[0014] The push block is slidably matched with the first slide rail;

[0015] The two clamp arms are slidably matched with the second slide rail, and the second slide rail and the first slide rail are arranged vertically relative to each other;

[0016] The rear ends of the two clamp arms are connected to the push block through connecting rods, and the front ends of the two clamp arms are respectively provided with clamping openings that match each other;

[0017] The reset rod is arranged in parallel with the second slide rail, and the two ends of the reset rod are respectively slidably matched with the two clamp arms. The two ends of the reset rod are respectively covered with preload springs, and the preload springs drive the two clamp arms to slide toward the middle.

[0018] The push block is connected to the clamping arms through connecting rods, so the push block slides relative to the two clamping arms, and the push block drives the clamping arms to close and separate. The front end of the clamping arm is provided with a clamping opening to facilitate clamping the end of the corrugated pipe.

[0019] Preferably, the feeding device comprises a vibrating plate, a sliding trough, a loading slide and a material moving block;

[0020] A feed port is provided on one end side wall of the feeding slideway, and the vibrating plate is connected to the feed port through the slide trough;

[0021] The other end of the feeding slideway is provided with an execution position;

[0022] The material shifting block is slidably matched with the loading slideway, and the material shifting block is provided with a material shifting notch for accommodating a single component corresponding to the feeding port. The material shifting block is driven by the second cylinder so that the material shifting notch reciprocates between the feeding port and the execution position.

[0023] The components can be neatly arranged and fed to the feed port through the sliding trough by the vibration plate. The components enter the material transfer gap through the feed port. After the components enter the material transfer gap, the second cylinder drives the material transfer block to push the components to the execution position. The components are at the execution position for the loading device to pick up and assemble at a fixed point.

[0024] Preferably, the loading device comprises an X-axis guide rail assembly, a Z-axis guide rail assembly and an actuator assembly;

[0025] The X-axis guide rail assembly includes an X-axis slide rail and an X-axis moving part slidably matched with the X-axis slide rail;

[0026] The X-axis slide rail is arranged across the positioning device and the feeding device;

[0027] The Z-axis guide rail assembly includes a Z-axis slide rail and a Z-axis moving part slidably matched with the Z-axis slide rail;

[0028] The Z-axis slide rail is arranged on the X-axis moving part;

[0029] The execution component is fixed to the Z-axis moving part.

[0030] When picking up materials, the X-axis moving part drives the Z-axis guide rail assembly to move between the positioning device and the feeding device. When it moves to the top of the feeding device and the specific actuator is above the actuator position, the Z-axis guide rail assembly drives the actuator downward to take the component located at the actuator position. After driving the component upward, the X-axis moving part drives the Z-axis guide rail assembly to the top of the positioning device, and the specific actuator is located above the clamping mouth. Then the component is assembled downward to the port of the bellows. The above is to realize the picking up and assembly of the component.

[0031] Preferably, the actuator is a loading actuator and / or a charging actuator. Different actuators are used for different component assembly requirements to realize step-by-step assembly of components according to different processes and workstations.

[0036] The active expansion sleeve is covered with the slide cylinder, and the slide cylinder is driven by the third cylinder.

[0037] When taking materials, the first positioning pin drives the active expansion sleeve downward to clamp the component hole, and the active expansion sleeve will clamp the component from the inside to the outside, and then transport the component upward to the port of the bellows of the positioning device. The first positioning pin first enters the bellows, and then the slide slides downward to slide the component from the active expansion sleeve into the port of the bellows, thereby achieving assembly.

[0038] Preferably, the active expansion sleeve comprises an upper fixed portion and a lower expansion portion; the fixed portion is fixed to the first positioning pin, and the expansion portion comprises a plurality of circumferentially distributed expansion petals.

[0039] The fixing portion can better fix the expansion flap, so that the expansion flap can provide sufficient elastic expansion.

[0040] Preferably, the loading actuator includes a fixing platform, a guide cylinder, a passive expansion sleeve, and a second positioning pin;

[0041] The fixed platform is vertically provided with a guide cylinder, the guide cylinder is rotatably matched with the fixed platform, the guide cylinder is provided with a driven wheel on the outside, the driven wheel is connected with the driving wheel through a synchronous belt, and the driving wheel is driven by the second motor;

[0042] The passive expansion sleeve is fixedly connected to the lower end of the guide cylinder;

[0043] The guide cylinder is provided with a second positioning pin, which can slide axially but not rotate circumferentially relative to the guide cylinder, and the second positioning pin extends downward from the top of the guide cylinder to the bottom of the passive expansion sleeve, and the side wall of the second positioning pin is provided with a tapered section which is thin at the top and thick at the bottom corresponding to the lower end of the expansion sleeve;

[0044] The lower end of the second positioning pin is configured as a conical structure, and the upper end of the second positioning pin is connected to the output end of the third cylinder for relative rotation.

[0045] It is suitable for taking materials that need to be rotated and assembled with the bellows. The second locating pin drives the active expansion sleeve downward into the component hole, and the second locating pin is driven to slide upward by the third cylinder. Since the second locating pin is provided with a tapered section, it will drive the passive expansion sleeve to expand outward, thereby locking the component. The component is then transported to the bellows port at the execution position through the X-axis guide rail assembly and the Z-axis guide rail assembly. The guide cylinder and the passive expansion sleeve are then driven to rotate by the second motor, and the component fixed on the outside of the passive expansion sleeve is rotated and locked in the port of the bellows. Finally, the second locating pin is driven downward to slide by the third cylinder, so that the passive expansion sleeve releases the lock on the component.

[0046] Advantages of the present invention:

[0047] This solution can realize the assembly of components at the ports of bellows in steps and processes for different types of components. At the same time, the turntable can realize the simultaneous assembly of multiple bellows.

[0067] The frame is provided with a loading device 4 , and the loading device 4 is arranged in a one-to-one correspondence with the feeding device 3 .

[0068] When assembling the present solution, the end of the bellows is fixed to the positioning device 2, the object is taken out from the feeding device 3 through the loading assembly, and then the object is placed at the end of the bellows and assembled in the loading assembly.

[0069] A feeding device 3 provides a component supply, and the components are assembled at the end of the bellows in steps through multiple feeding devices 3 and charging devices 4. After the previous component of the bellows is assembled, the turntable 1 drives the bellows to rotate to the next feeding device 3 and charging device 4 to assemble the next component.

[0070] By assembling the components of the bellows in multiple steps and positions, the overall assembly process becomes smoother and more efficient.

[0071] Combination Figure 2 As shown, the positioning devices 2 are divided into 6 groups, and the positioning devices 2 in the same group are respectively arranged corresponding to the two ends of the corrugated pipe. The two ends of the corrugated pipe are assembled at the same time, which can significantly improve the assembly efficiency.

[0072] The turntable 1 is rotatably matched with the frame, and the turntable 1 is driven by a first motor. The turntable 1 can be driven to rotate step by step more conveniently by the first motor, so that the corrugated pipe can be rotated and transported according to the workstation.

[0073] Combination Figure 3 As shown, the positioning device 2 includes a push block 5, a clamping arm 6 and a reset rod 7.

[0074] The push block 5 is slidably matched with the first slide rail.

[0075] The two clamping arms 6 are slidably matched with the second slide rail, and the second slide rail and the first slide rail are arranged vertically relative to each other.

[0076] The rear ends of the two clamping arms 6 are connected to the push block 5 through connecting rods, and the front ends of the two clamping arms 6 are respectively provided with clamping openings 9 that match each other.

[0077] The reset rod 7 is arranged parallel to the second slide rail, and the two ends of the reset rod 7 are respectively slidably matched with the two clamping arms 6. The two outer sleeves of the reset rod 7 are provided with pre-tightening springs 8, and the pre-tightening springs 8 drive the two clamping arms 6 to slide toward the middle. Specifically, the outer end of the pre-tightening spring 8 is fixed to the reset rod 7, and the inner end of the pre-tightening spring 8 presses inward against the clamping arms 6.

[0078] The push block 5 is connected to the clamping arms 6 through connecting rods, so the push block 5 slides relative to the two clamping arms 6, and the push block 5 drives the clamping arms 6 to close and separate. The front end of the clamping arm 6 is provided with a clamping opening 9 to facilitate clamping the end of the corrugated pipe.

[0079] Combination Figure 4 and Figure 5 As shown, the feeding device 3 includes a vibrating plate 10 , a sliding trough 11 , a loading slide and a material moving block 12 .

[0080] A feed port is disposed on a side wall at one end of the loading slideway, and the vibration plate 10 is connected to the feed port through the slide trough 11 .

[0081] An execution position 13 is provided at the other end of the feeding slideway.

[0082] The material moving block 12 is slidably matched with the loading slideway. The material moving block 12 is provided with a material moving notch for accommodating a single component corresponding to the feed port. The material moving block 12 is driven by the second cylinder so that the material moving notch reciprocates between the feed port and the execution position 13.

[0083] The components can be neatly arranged through the vibration plate 10 and fed to the feed port through the slide trough 11. The components enter the material transfer gap through the feed port. After the components enter the material transfer gap, the second cylinder drives the material transfer block 12 to push the components to the execution position 13. The components are at the execution position 13 for the loading device 4 to pick up and assemble at a fixed point.

[0084] Combination Figure 6 As shown, the loading device 4 includes an X-axis guide rail assembly, a Z-axis guide rail assembly and an actuator assembly.

[0085] The X-axis guide rail assembly includes an X-axis slide rail 14 and an X-axis moving member 15 slidably matched with the X-axis slide rail 14 .

[0086] The X-axis slide rail 14 is arranged across the positioning device 2 and the feeding device 3 .

[0087] The Z-axis guide rail assembly includes a Z-axis slide rail 16 and a Z-axis moving member 17 slidably matched with the Z-axis slide rail 16 .

[0088] The Z-axis slide rail 16 is disposed on the X-axis moving member 15 .

[0089] The actuator is fixed to the Z-axis moving member 17 .

[0090] When picking up materials, the X-axis moving part 15 drives the Z-axis guide rail assembly to move between the positioning device 2 and the feeding device 3. When it moves to the top of the feeding device 3 and the specific execution component is above the execution position 13, the Z-axis guide rail assembly drives the execution component downward to take the component located at the execution position 13. After driving the component upward, the X-axis moving part 15 drives the Z-axis guide rail assembly to the top of the positioning device 2, and the specific execution component is located above the clamp 9, and then the component is assembled downward to the port of the bellows. The above is to realize the picking up and assembly of the components.

[0091] The actuators are feeding actuators and loading actuators. Different actuators are used for different component assembly requirements to realize step-by-step assembly of components according to different processes and workstations. The feeding actuator is used for components that do not need to rotate, such as the hexagonal nut 26, the steel sleeve and the conical nut 27, and the loading actuator is used for components that need to rotate, such as the plastic retainer.

[0092] Combination Figure 7 and Figure 8 As shown, the feeding actuator includes an end platform 18 , a first positioning pin 19 , an active expansion sleeve 21 and a slide cylinder 20 .

[0093] The end table 18 is fixed to the Z-axis moving member 17 .

[0094] The first positioning pin 19 is fixed downwardly to the Z-axis moving member 17 .

[0095] The active expansion sleeve 21 is disposed on the outer shell of the first positioning pin 19 , and the first positioning pin 19 below the active expansion sleeve 21 is configured as a conical structure.

[0096] The active expansion sleeve 21 is covered with the slide cylinder 20 , and the slide cylinder 20 is driven by the third cylinder.

[0097] When taking the material, the first positioning pin 19 drives the active expansion sleeve 21 downward to clamp the component hole, and the active expansion sleeve 21 will clamp the component from the inside to the outside, and then transport the component upward to the port of the bellows of the positioning device 2. The first positioning pin 19 first enters the bellows, and then the slide 20 slides downward to slide the component from the active expansion sleeve 21 into the port of the bellows, thereby achieving assembly.

[0098] The active expansion sleeve 21 includes an upper fixed portion and a lower expansion portion. The fixed portion is fixed to the first positioning pin 19, and the expansion portion includes a plurality of expansion petals distributed circumferentially. In order to better allow the active expansion sleeve 21 to enter the component hole, the lower end of the active expansion sleeve 21 is set to a conical structure.

[0099] The fixing portion can better fix the expansion flap, so that the expansion flap can provide sufficient elastic expansion.

[0100] Combination Fig. 9 As shown, the loading actuator includes a fixing platform 22 , a guide cylinder 23 , a passive expansion sleeve 25 , and a second positioning pin 24 .

[0101] The fixed platform 22 is vertically provided with a guide cylinder 23, and the guide cylinder 23 is rotatably matched with the fixed platform 22. A driven wheel is provided outside the guide cylinder 23, and the driven wheel is connected to the driving wheel through a synchronous belt, and the driving wheel is driven by the second motor.

[0103] The guide cylinder 23 is provided with the second positioning pin 24, which can slide axially relative to the guide cylinder 23 but cannot rotate in a circle. In this embodiment, the second positioning pin 24 is splined with the guide cylinder to which it belongs, and the second positioning pin 24 extends downward from the top of the guide cylinder 23 to the bottom of the passive expansion sleeve 25. The side wall of the second positioning pin 24 is provided with a tapered section that is thin at the top and thick at the bottom corresponding to the lower end of the expansion sleeve.

[0104] The lower end of the second positioning pin 24 is configured as a conical structure, and the upper end of the second positioning pin 24 is connected to the output end of the third cylinder for relative rotation.

[0105] It is suitable for taking materials that need to be rotated and assembled with the bellows. The second positioning pin 24 drives the active expansion sleeve 21 downward into the component hole, and the second positioning pin 24 is driven to slide upward by the third cylinder. Since the second positioning pin 24 is provided with a tapered section, it will drive the passive expansion sleeve 25 to expand outward, thereby locking the component, and then transport the component to the bellows port of the execution position 13 through the X-axis guide rail assembly and the Z-axis guide rail assembly, and then the guide cylinder 23 and the passive expansion sleeve 25 are driven to rotate by the second motor, and the component fixed on the outside of the passive expansion sleeve 25 is rotated and locked in the port of the bellows, and finally the second positioning pin 24 is driven downward by the third cylinder to slide, so that the passive expansion sleeve 25 releases the lock on the component.

[0106] This solution can realize the assembly of components of different types at the port of the bellows in steps and processes. At the same time, the turntable 1 can realize the simultaneous assembly of multiple bellows. The whole assembly process is very smooth and efficient, which significantly improves the quality of assembly.

When the first push cylinder 29 drives the push block 5 to slide toward the clamp 9, the clamp 9 opens, and the two ends of the bellows are placed upward in the clamp 9, wherein the mouth of the bellows is upward against the upper limit plate 36, which is used to limit the upper end of the bellows, and then the first push cylinder 29 is driven in reverse, and the clamp 9 clamps the bellows.

[0109] The second group is used for buffering transition, and both ends of the bellows are fixed at this positioning device 2 respectively.

[0110] The third and fourth groups are provided with corresponding feeding actuators for assembling the hexagonal nut 26 and the steel sleeve.

The front end of the second slide bar 35 is vertically fixed with a push plate 31. The push plate 31 slides along the push block 5 toward the clamping opening 9. When the second push cylinder 30 drives the push block 5 of the sixth group positioning device 2 to slide toward the clamping opening 9, the clamping opening 9 opens, and at the same time, the push plate 31 moves toward the clamping opening 9 to push out the bellows, and the bellows falls off from the clamping opening 9. The second slide bar 35 between the push plate 31 and the second fixed plate 34 is covered with a return spring 32.

[0113] The frame is provided with an outer ring 28 corresponding to the outer periphery of the turntable 1, and the outer ring 28 is provided corresponding to the lower part of the clamping opening 9 of each group of positioning devices 2.
