Description

Technical Field

[0001] The invention relates to the technical field of elevator hydraulic buffer processing equipment, in particular to an elevator hydraulic buffer spring press machine. Background Art

[0002] The main function of the elevator hydraulic buffer is to absorb and slow down the impact energy of the car when the car descends at an excessive speed due to loss of control or failure, or hits the pit at an abnormal speed due to other reasons during the operation of the elevator, to prevent damage to the mechanism caused by hard collision, thereby protecting the safety of passengers and equipment. When producing and processing the elevator hydraulic buffer, the buffer's spring needs to be pressed onto the upper part of the plunger assembly, and then threaded and sealed with the plunger cap, thereby improving the processing efficiency of the elevator hydraulic buffer.

[0003] In the prior art, such as the invention patent disclosed in the publication number: CN113334055B, a press-fitting machine for assembling elevator hydraulic buffer springs, including: a press-fitting table; a plunger assembly positioning and feeding mechanism; a spring feeding conveyor; a plunger cap conveyor; a spring plunger cap picking and pressing mechanism; the spring plunger cap picking and pressing mechanism is arranged directly above the plunger assembly positioning and feeding mechanism, and the spring feeding conveyor and the plunger cap conveyor are symmetrically arranged on both sides of the spring plunger cap picking and pressing mechanism; the spring plunger cap picking and pressing mechanism includes: a top rectangular frame; a translation lifting assembly; a pressing and picking assembly. The equipment can automatically assemble the elevator hydraulic buffer and can automatically compress the spring to connect the plunger caps to the plunger caps, saving labor and improving efficiency.

[0004] Although the above patented device can press the spring into the plunger assembly, when the above device feeds the pressed spring, since the spring body is an elastic structure, the arranged guided feeding method of the conveyor can easily cause the spring to fall over, and also reduces the stability of the clamping and positioning of the device.

At the same time, when the above device assembles the spring and the plunger assembly, the device needs to avoid the position, resulting in a long bottleneck time in the processing procedure of the above device, reducing the overall processing speed of the spring and plunger assembly of the device. Therefore, an elevator hydraulic buffer spring press machine is needed to solve the above problems. Summary of the invention

When the newly loaded plunger assembly 11 is clamped and limited, the two groups of positioning slides 3241 can be displaced centripetally under the meshing guide of the transmission gear 325, so that the two groups of limiting clamps 3242 can clamp and limit the plunger assembly 11, and the closed bottom plate 321 located at the bottom of the threaded slide 322 can synchronously close and limit the bottom of the plunger assembly 11 when the limiting clamp 3242 clamps the plunger assembly 11, thereby further improving the stability of limiting and clamping the plunger assembly 11.

[0061] like Fig.11 When the threaded slide 322 drives the two sets of limiting clamps 3242 to completely limit the plunger assembly 11, the closed bottom plate 321 and the bottom of the limiting rotating sleeve 327 are completely fitted and closed, and the top of the limiting clamp 3242 is stepped, which can provide sufficient guiding basis for the loading of the spring 10, and can also provide sufficient operating space for the subsequent three-jaw chuck 55 to drive the plunger cap 9 to close the upper part of the plunger assembly 11.

[0062] like Fig.13 , Fig.14 , Fig.15 and Fig.16 The driving gear 57 located in the middle is meshed and connected with the six groups of driven gears 53, which can effectively improve the transmission efficiency and stability of the equipment. The three-jaw chuck 55, the limiting clamp 3242 and the fixing clamp 422 are all coaxially arranged, which can facilitate the subsequent three-jaw chuck 55 to drive the plunger cap 9 to quickly and accurately align the threaded sealing of the plunger assembly 11 inside the limiting clamp 3242, and also facilitate the subsequent assembled plunger assembly 11 to be quickly and accurately guided to the fixing clamp 422 for unloading, thereby improving the guiding accuracy of the plunger assembly 11. The fixing clamp 422 is fixedly connected with the plunger assembly 11 through the positioning baffle 421, and the positioning baffle 421 can stably limit the assembled plunger assembly 11 to prevent the plunger assembly 11 from falling off during unloading.

[0063] Working principle: Before use, the staff can position the external robot arm close to the spring feeding device 2, so as to facilitate the subsequent simultaneous introduction of multiple groups of plunger assemblies 11 into the guide device 3 for feeding operations. At the same time, the feeding module of the plunger cap 9 can be positioned at the rear of the fixed top plate 6, so as to facilitate the subsequent feeding operations of batches of plunger caps 9. The staff can introduce multiple groups of plunger caps 9 to be pressed into the spring feeding device 2, so as to facilitate the subsequent continuous provision of springs for feeding the guide device 3. When the plunger assembly 11 is fed, Figure 6 and Figure 7 As shown, in the initial state, the flip card seat 31 is located at the bottom. At this time, the six groups of pre-pressing devices 324 on the upper part of the limit device 32 are just at the same level and directly opposite to the external feeding robot arm. Then the external robot arm can guide the plunger assembly 11 to the top of the six groups of pre-pressing devices 324, and then the robot arm can guide the plunger assembly 11 between the two groups of pre-pressing devices 324. Fig.10 and Fig.11 , the reduction motor 323 is started, the reduction motor 323 can drive the active bevel gear 329 at the bottom to rotate, and the active bevel gear 329 can synchronously drive the six sets of driven bevel gears 3211 to rotate, and the driven bevel gears 3211 can synchronously drive the six sets of fixed screw rods 3210 to rotate, and the six sets of fixed screw rods 3210 can synchronously drive the six sets of threaded slides 322 to synchronously centrifugal displacement, the threaded slide 322 can synchronously drive the closed bottom plate 321 and the positioning slide 3241 to synchronously move outward, and the positioning slide 3241 can synchronously drive the transmission rack 32 47 and the limiting clamp 3242 are synchronously moved outward, and the bottoms of the two sets of relative positioning slides 3241 are meshed with each other through the transmission rack 3247 and the transmission gear 325, so that the two sets of limiting clamps 3242 can be synchronously displaced toward the middle plunger assembly 11 under the guide of the transmission gear 325 until the two sets of limiting clamps 3242 have completed the limiting of the plunger assembly 11. At the same time, the closed bottom plate 321 located at the bottom of the limiting clamp 3242 can limit the bottom of the plunger assembly 11, thereby completing the clamping and limiting operation of the plunger assembly 11. After the clamping is completed, Figure 7 At this time, the servo motor 37 can synchronously drive the two sets of transmission screws 310 to rotate through the synchronous pulley 35 and the synchronous belt 36. The two sets of transmission screws 310 can be threadedly connected with the threaded sleeve 33, thereby driving the flip card seat 31 and the two sets of limit devices 32 to lift. When lifted to the top, the spring loading and pre-pressing begins. Figure 5 Haowei Fig.11After the limit device 32 is lifted to the specified position, the guide cylinder 21 is started, and the guide cylinder 21 can drive the alignment chuck 24 to move downward. When the alignment chuck 24 moves to the position where it fits with the upper part of the two sets of pre-pressing devices 324, the spring lower bin 22, the two sets of limit clamps 3242 and the plunger assembly 11 are coaxial, and then the stepper motor 25 is started. The stepper motor 25 can synchronously drive the six sets of closed guide plates 29 and the guide slide shaft 210 to move centripetally through the transmission turntable 28 and the guide slide groove 27, and the six sets of closed guide plates 29 can release the spring lower bin 22. The bottom opening of the silo 22 is limited. At this time, the springs 10 inside the spring lower silo 22 can be introduced one by one along the spring lower silo 22 into the space between the two sets of limiting clamps 3242. The two sets of limiting clamps 3242 can axially limit the springs 10 so that the springs 10 can be stably sleeved to the outside of the plunger assembly 11. After the springs 10 are led out from the spring lower silo 22, the stepper motor 25 is synchronously reversed and started, so that the six sets of closed guide plates 29 can close the bottom of the spring lower silo 22 again, thereby completing the unloading operation of a single spring 10. Fig.11 and Fig.12 When the spring 10 is pre-stressed, in the initial state, the pre-stressing card plate 3248 is retracted inside the ball slide 3244, and the ball slide 3244 is at the top inside the limiting clamp 3242. When the spring 10 is limited inside the two sets of limiting clamps 3242, the two sets of double-axis cylinders 3245 can drive the pre-stressing card plate 3248 to be guided out, thereby completing the top limit of the spring 10. At the same time, the micro motor 3246 can drive the two sets of pre-stressing card plates 3248 to move the spring 10 downward through the support screw 3243. Figure 7After the pre-pressing is completed, the swing cylinder 38 is started, and the swing cylinder 38 can drive the guide clamp 39 and the two sets of limit devices 32 to flip 180 degrees, so that the plunger assembly 11 and the pre-pressed spring 10 can be coaxially aligned with the press-fitting device 5. When the top of the plunger assembly 11 is closed, the six sets of three-claw chucks 55 can clamp and limit the six sets of plunger caps 9 provided by the external feeding module, and then the press-fitting cylinder 51 can drive the transmission guide seat 58 and the six sets of three-claw chucks 55 to move downward synchronously. When the three-claw chuck 55 drives the plunger cap 9 to be positioned to the upper part of the plunger assembly 11, the screw at the bottom of the plunger cap 9 can be just inserted into the prefabricated threaded hole at the top of the plunger assembly 11, and the alignment chassis 52 continues Continuously move downward, at this time the spring guide seat 54 is in a compressed state, providing sufficient elastic force to support the threaded connection between the plunger cap 9 and the plunger assembly 11, and at the same time the transmission motor 56 is started, and the transmission motor 56 can synchronously drive the six groups of driven gears 53 to rotate through the driving gear 57, and the six groups of driven gears 53 can synchronously drive the six groups of plunger caps 9 to threadedly connect with the plunger assembly 11. After the plunger cap 9 is limited, the three-claw chuck 55 releases the limit on the plunger cap 9, and at the same time the press-fitting cylinder 51 can drive the alignment chassis 52 to lift and reset, and at this time the double-axis cylinder 3245 can release the pre-pressure on the spring 10 through the pre-pressure card plate 3248, thereby completing the press-fitting operation on the spring 10. After the press-fitting is completed, Figure 7 The servo motor 37 drives the transmission screw 310 to reverse through the synchronous pulley 35 and the synchronous belt 36, so that the flip card seat 31 moves downward. Fig.14 , the alignment device 42 can drive the threaded guide seat 43 and the alignment device 42 to rise synchronously, so that the six groups of alignment devices 42 can be coaxially aligned with the six groups of clamped and pressed plunger assemblies 11, and then the reduction motor 323 can synchronously drive the six groups of pre-pressing devices 324 to release the limit on the plunger assembly 11. At this time, the plunger assembly 11 can fall between the two groups of fixed clamps 422 through the limiting rotating sleeve 327 at the bottom of the pressing chuck 326, and the positioning baffle 421 can limit the bottom of the plunger assembly 11. Then the alignment device 42 can drive the six groups of alignment devices 42 and the plunger assembly 11 to move down to the upper part of the conveyor 45, and the fixed clamp 422 is automatically opened under the drive of the clamping cylinder 424, and the plunger assembly 11 pressed inside the fixed clamp 422 is introduced into the upper part of the conveyor 45 for export.
