And the indexing mechanism 13 is connected with the indexing disc 11, so that the indexing disc 11 is driven to move at the same angle.

The positioning mechanism 12 can provide a consistent positioning reference surface for the rocker arm assembly 6, which is beneficial to ensuring the consistency of the position of the rocker arm assembly 6 during assembly, and indirectly ensures the positioning accuracy and subsequent assembly accuracy. The angle of rotation of the index plate 11 can be determined according to the number of the positioning mechanisms 12, so that the index mechanism 13 can accurately rotate the index plate 11 to a proper angle. Therefore, the positioning mechanism 12 can stay at the corresponding station, so that a worker or other devices can conveniently perform corresponding processes, and parts on the positioning mechanism 12 can be accurately operated. Thus, a positioning device 1 capable of realizing precise assembly can be formed, so that the assembly work of the rocker arm assembly 6 can be completed accurately and rapidly. The repeated circulation action is beneficial to improving the whole assembly efficiency.

In a possible embodiment, the positioning mechanism 12 comprises a positioning element 121, a stop 122 and a slider 123. The positioning member 121, the positioning member 121 is provided with a positioning groove.

A sliding member 123 having a slot for receiving the rocker arm assembly 6, the sliding member 123 being movably connected to the positioning member 121 for adjusting the position of the slot relative to the positioning slot.

Thus, the position of the rocker arm assembly 6 during assembly can be ensured through the stop part 122, the position reliability of the rocker arm assembly 6 is further ensured, the precision of the later period during operation of the rocker arm assembly 6 is improved, and the assembly efficiency and the assembly quality are improved. The arrangement of the sliding part 123 is beneficial to adapting to the assembly requirements of different stations, and has better flexibility and practicability.

The stop member 122 may be partially disposed in the positioning groove, or may be disposed in the positioning groove as a whole, and specifically may be flexibly disposed according to the specification of the positioning member 121 and the specification of the rocker arm assembly 6.

In one embodiment, in the plurality of sets of positioning mechanisms 12, pushing mechanisms 14 are disposed below at least two sets of positioning mechanisms 12 in a one-to-one correspondence; the pushing mechanism 14 is connected to the slider 123 to adjust the position of the slot.

And a fourth linear driver 143 having a movable end detachably coupled to the push plate 142 to move the push plate 142 closer to or away from the push stage 141. Therefore, when the push plate 142 touches the push table 141, the sliding member 123 can be driven to move, thereby realizing the adjustment of the slot position. For example, after the rocker arm 63 is put on the positioning mechanism 12, the slider 123 may bring the needle valve element 61 located in the slot hole close to the rocker arm 63, and the needle valve element 61 may be locked in the insertion hole of the rocker arm 63, so as to realize the assembling work of the rocker arm 63 and the needle valve element 61.

Further, the fourth linear driver 143 may be configured as a cylinder. Of course, the fourth linear actuator 143 may be configured as any suitable linear actuator such as a hydraulic cylinder and a linear actuator, and the disclosure is not limited thereto.

In the present disclosure, the push plate 142 can be configured in any suitable configuration.

In one possible design, the pushing plate 142 includes a horizontal section and vertical sections respectively disposed at two ends of the horizontal section, and the pushing platform 141 is disposed between the two vertical sections, i.e., the pushing platform 141 is located above the horizontal section. Thus, the pushing or pulling action of the pushing table 141 can be realized by changing the moving direction of the linear driver, and one structure, two functions and good practicability can be realized.

In another possible design, i.e. in at least two groups of pushing mechanisms 14, the pushing plate 142 of one group of pushing mechanisms 14 is arranged on the side close to the center of the indexing disk 11, in which case the sliding member 123 can be driven to move towards the outside when the movable end of the fourth linear driver 143 moves towards the outside (the side away from the center of the indexing disk 11); the push plates 142 of the other group of pushing mechanisms 14 are arranged on the side close to the edge of the indexing disk 11, in which case the slide 123 is driven to move towards the inside when the movable end of the fourth linear actuator 143 moves towards the inside (the side pointing towards the center of the indexing disk 11). Therefore, the position of the sliding member 123 can be flexibly adjusted according to the station where the positioning mechanism 12 is located.

In yet another embodiment, the pushing mechanism 14 can be configured as an electrostrictive or magnetostrictive member, i.e., the length of the electrostrictive or magnetostrictive member is switched by switching the power-on and power-off states, and the sliding member 123 is indirectly driven to move, so that the flexible adjustment of the slot hole position can be realized. In this regard, conventional modifications of the prior art may be made by those skilled in the art, and the disclosure is not limited thereto.

In yet another embodiment, the pushing mechanism 14 may also be configured as a combination of a motor and a screw transmission mechanism, whereby the rotation of the motor is converted into the linear movement of the screw to adjust the position of the slider 123. That is, under the technical idea of the present disclosure, a person skilled in the art can flexibly assemble the pushing mechanism 14 according to the application environment, and the present disclosure does not limit this.

In order to improve the accuracy of the operation of the swing arm assembly 6, the positioning mechanism 12 may further include a guide plate 124, the guide plate 124 may be detachably connected to the positioning member 121, and a guide hole 125 opposite to the positioning slot may be formed in the guide plate 124. In this way, the positioning pin 64 in the rocker arm assembly 6 can be accurately inserted into the fitting hole site of the rocker arm 63, and the fitting quality is ensured.

In one embodiment, the positioning mechanisms 12 are arranged in four sets, with the angle of rotation between adjacent positioning mechanisms 12 being 90 °. Thus, the index plate 11 rotates by 90 ° as well.

In the present disclosure, a threaded hole or a countersunk hole is provided in the positioning mechanism 12, and the positioning mechanism 12 is detachably attached to the index plate 11 by a bolt or a screw. In order to ensure the positioning reliability, at least three groups of threaded holes or countersunk holes are arranged, so that the stability and the reliability of the position of the positioning mechanism 12 can be ensured when the positioning mechanism rotates, and the positioning accuracy is prevented from being influenced by vibration.

In other embodiments, the positioning mechanism 12 may be connected to the index plate 11 in a snap-fit manner, for which a person skilled in the art may flexibly set the positioning mechanism according to actual needs.

In an alternative embodiment, the indexing mechanism 13 is configured as a cam divider. Of course, the cam divider may be directly used as the indexing mechanism 13, or a mechanical structure may be further provided on the index plate 11 in the area below each positioning mechanism 12 on the basis of the above, so that the rotation accuracy of the index plate 11 is ensured by the cooperation of the mechanical structure and the cam divider. For example, a groove is formed in the bottom of the dividing plate 11, a boss which can move in the vertical direction is further arranged below the dividing plate 11, and when the dividing plate 11 rotates to 90 degrees, the boss can be quickly clamped into the groove, so that the position of the dividing plate 11 is locked, the positioning accuracy is prevented from being influenced by the fact that the dividing plate continues to rotate under the action of inertia, and the position accuracy of the positioning mechanism 12 is guaranteed.

Specifically, the cam indexer is configured as a four-position indexer, model number RU60 DF-04.

In one specific embodiment provided by the present disclosure, the positioning apparatus 1 may further include a fourth detection mechanism and a fourth controller.

The fourth controller is respectively connected with the indexing mechanism 13 and the fourth detection mechanism in a communication mode so as to control the indexing mechanism 13 to execute corresponding actions according to the current position of the positioning mechanism 12. For example, when the positioning mechanism 12 is detected to be at the target station, the indexing mechanism 13 stops rotating so as to enable the device corresponding to the current station to operate the positioning mechanism 12, and after the operation is completed, the indexing mechanism 13 drives the indexing disc 11 to rotate so as to enable the positioning mechanism 12 to move to the next station. Thus, the position of the positioning mechanism 12 is regulated and controlled in real time, and intelligent control is realized.

In one specific embodiment provided by the present disclosure, the fourth detection mechanism may be configured as a fourth displacement sensor or a fourth distance sensor, and of course, both the fourth displacement sensor and the fourth distance sensor may be configured.

Of course, wired transmission of data may also be achieved through a communication cable or the like, which is not limited by the present disclosure.

According to a second aspect of the present disclosure, there is provided a feed device for a rocker arm in a diaphragm carburetor. The feeding device 2 can feed the swing arm 63 into the positioning device 1 provided in the first aspect, thereby improving the assembly efficiency and the assembly accuracy. Fig. 1 to 13 show one embodiment, and the structure of the feeding device 2 will be described in detail below with reference to the drawings.

Referring to fig. 1 to 13, the feeding device for the rocker arm in the diaphragm carburetor includes an adjusting mechanism 21, an adsorption mechanism 22, a transmission mechanism 23, and an epicyclic mechanism 24.

And an adjusting mechanism 21 for aligning the plurality of swing arms 63 in the same posture and outputting the swing arms 63 in a single row. And an adsorption mechanism 22 for picking up the swing arm 63 from the pick-up position and releasing the swing arm 63 from the discharge position, the adsorption mechanism 22 having a suction nozzle for adsorbing the swing arm 63. One end of the transmission mechanism 23 is communicated with the output port of the adjusting mechanism 21, and the other end is communicated to the material taking position, so that the rocker arms 63 output by the adjusting mechanism 21 are conveyed to the material taking position in a single row at the same posture. And the movable end of the turnover mechanism 24 is connected to the adsorption mechanism 22 and is used for driving the adsorption mechanism 22 to move between the material taking position and the material placing position.

The working process of the feeding device 2 can be summarized as follows: the adjustment mechanism 21 integrates a plurality of rocker arms 63 having different postures into rocker arms 63 having the same posture, and derives them in a single row. Since the transfer mechanism 23 communicates with the adjustment mechanism 21, the swing arms 63 having the same posture can be conveyed to the adsorption mechanism 22. And the suction mechanism 22 is driven by the revolving mechanism 24 to suck the rocker arm 63 from the material taking position on the conveying mechanism 23, align the rocker arm 63 with the corresponding station, and release the rocker arm 63, so that the rocker arm 63 can be placed in the positioning mechanism 12 in the positioning device 1 provided in the first aspect. Thereby, the feeding work of the swing arm 63 is completed.

Through the technical scheme, the rocker arm 63 can be placed in the tool (namely the positioning mechanism 12 provided by the first aspect) corresponding to the material placing position in the same posture, so that the accuracy and consistency of the position of the rocker arm 63 during assembly can be ensured, and the assembly quality and the assembly efficiency are favorably ensured. Therefore, the method can replace the traditional operation mode, can meet the production requirement of quality and quantity guarantee, can ensure the productivity even under the condition of larger production requirement, and can meet the requirement of industrial production.

It should be noted that the material taking position is a position where the adsorption mechanism 22 sucks the rocker arm 63, and in the present disclosure, the material taking position is located on the conveying mechanism 23; the discharging position is the position where the adsorption mechanism 22 releases the rocker arm 63, and in the present disclosure, the discharging position is located on the positioning device 1.

In the embodiments provided by the present disclosure, the transport mechanism 23 may be configured in any suitable configuration.

In one embodiment, the transfer mechanism 23 may include a guide 231 and a vibrator 232. The guide 231 has a basic size in the Y direction, and the guide 231 is provided with a guide groove extending in the Y direction, and the guide groove is formed in a structure corresponding to the swing arm 63. And a vibrator 232 disposed at the bottom of the guide 231 for vibrating the guide 231 so that the swing arm 63 can move to the material taking position through the guide groove.

In this way, the rocker arm 63 can move along the guide slot by the power provided by the adjusting mechanism 21, and since the guide slot has a certain length, the rocker arm 63 is easy to stop or stack due to insufficient power during the movement of the guide slot, so that the rocker arm 63 is difficult to reach the material taking position smoothly. Therefore, by the vibration of the vibrator 232, it is possible to provide sufficient power to move the swing arm 63 to the material taking position along the extending direction of the guide groove. By the design, the rocker arm 63 can be rapidly and smoothly transmitted, the continuity of working beats is guaranteed, and the production efficiency is indirectly guaranteed.

In the present disclosure, the vibrator 232 is prior art, and those skilled in the art can make routine improvements on the basis of the commercially available vibrator 232.

In addition, in the present disclosure, the adjustment mechanism 21 is configured as a vibrating disk. Since the vibrating disk is prior art, it will not be described in detail here.

In one embodiment, the transfer mechanism 23 further includes a pressing plate 233, and the pressing plate 233 is disposed above the guide groove to define the position of the swing arm 63, thereby not only preventing the swing arm 63 from being released from the guide groove during movement, but also ensuring consistency of the posture of the swing arm 63 so that the suction mechanism 22 can effectively suck the swing arm 63.

The pressing plate 233 may be integrally formed with the guide 231, or may be connected to the guide 231 by any suitable fastening member such as a screw and a nut, and thus, those skilled in the art may flexibly set the pressing plate according to the application environment.

In the present disclosure, the transmission mechanism 23 further includes a stopper 234, and the stopper 234 is provided at an end of the guide groove to prevent the swing arm 63 from coming out of the guide groove. In other words, the stopper 234 can stop the swing arm 63 to prevent the swing arm 63 from spilling, which is a waste of resources.

In another embodiment, the transmission mechanism 23 may further include a transmission belt and a motor, that is, the transmission belt is driven by the rotation of the motor to move, so as to realize the transmission of the swing arm 63, and a person skilled in the art may also flexibly configure the transmission mechanism according to actual requirements, and the disclosure is only exemplary.

And a traverse unit 243 connected to an upper portion of the support base 241, wherein a movable end of the traverse unit 243 is movable in the X direction, and a movable end of the traverse unit 243 is connected to the lifting unit 242. In this way, the spatial position of the suction mechanism 22 can be adjusted by the movement of the lifting unit 242 and the traverse unit 243.

Specifically, the traverse assembly 243 may include a second linear actuator, a traverse rail, and a first guide shoe.

Wherein, the telescopic end of the second linear actuator is connected to the first guide block to drive the first guide block to move along the cross rail, thereby indirectly adjusting the position of the lifting assembly 242, that is, adjusting the position of the adsorption mechanism 22.

Accordingly, the lift assembly 242 may include a third linear drive, a vertical rail, and a second guide block. And a third linear actuator connected to the traverse assembly 243, and a telescopic end of the third linear actuator is movable in the Z direction. And the vertical rail is arranged on the third linear driver and extends along the Z direction. And a second guide block embedded on the vertical rail and connected to the adsorption mechanism 22. The telescopic end of the third linear actuator is connected to the second guide block to drive the second guide block to move along the vertical rail, thereby adjusting the position of the adsorption mechanism 22.

It should be noted that the second linear actuator and the third linear actuator may be configured as any of an air cylinder, a hydraulic cylinder, a linear module, and the like. The second linear actuator and the third linear actuator may be flexibly configured according to actual conditions by those skilled in the art, and therefore, detailed description thereof will not be provided herein.

In one embodiment, the suction mechanism 22 may include a second vacuum pump, a gun nozzle, and a suction cup. The gun nozzle is communicated with the vacuum pump. The sucking disc is arranged at the bottom of the gun nozzle and communicated with the gun nozzle.
