Description

Technical Field

[0001] The utility model belongs to the field of impeller processing, in particular to a turntable used for punching an injection port of an impeller. Background Art

[0002] In electricity and energy, a rotor refers to the component of a wind turbine that converts wind energy into mechanical energy. The crossflow impellers in air conditioners are composed of multiple rotors, commonly known as mid-rotor rotors. Mid-rotor rotors are typically formed in one go using injection molding. For later assembly and use, a stamping mechanism is required to remove the injection port from the formed rotor.

[0003] In the prior art, a rotating table is generally provided on a machine platform, and a circle of material seats are provided on the rotating table. The material seats are used to place the middle-wind wheel, and a punching mechanism is provided on the machine platform facing the rotating table. When the injection port on the middle-wind wheel is to be removed, the rotating table rotates one station, and the current material seat rotates to the bottom of the punching mechanism. The punching mechanism punches the middle-wind wheel in the current material seat to remove the injection port. After the punching is completed, the rotating table rotates one position, and the punching mechanism punches the next middle-wind wheel. Although this can also complete the punching of the injection port on the middle-wind wheel well, it cannot guarantee that it will be completed in one go. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a turntable for punching the injection port of the middle wind wheel, aiming to solve the problem that the existing turntable for punching the injection port of the middle wind wheel cannot guarantee that the injection port on the wind wheel can be punched in one go.

[0015] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0017] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0018] Combine Figure 1-3 As shown, the turntable includes a machine 1, a rotatable turntable 2 is provided on the machine 1, a belt loading platform 3 and a belt unloading platform 4 are respectively provided on the machine 1 facing the turntable 2, and a transfer assembly 5 is provided between the belt loading platform 3 and the belt unloading platform 4 and the turntable 2, a circle of notches is opened on the turntable 2, a carrier plate 6 is provided on the notch, and a pair of rotating seats 7 are rotatably provided on each carrier plate 6, a chuck 8 is provided above the rotating seat 7, and a pulley 9 and a linkage wheel 10 are provided from top to bottom below, and a belt 11 is sleeved between the same pair of pulleys 9, and a linkage mechanism is also provided on the machine 1 facing the turntable 2, and the linkage mechanism drives the same pair of linkage wheels to rotate.

[0019] The impeller is generally formed in one piece using injection molding. For later assembly and use, the impeller requires a stamping mechanism to remove the injection port. In this embodiment, a stamping mechanism is provided on the machine corresponding to the linkage mechanism.

[0020] When using this turntable to complete the punching of the injection port of the wind wheel, the turntable first rotates counterclockwise. When the turntable rotates one station, if the current rotating seat rotates to the punching station, the turntable stops rotating and remains stationary. The punching shaft of the punching mechanism punches the injection ports of the two wind wheels. When the punching is completed, the punching shaft is still in contact with the wind wheel. The linkage mechanism drives the two rotating seats to rotate. The wind wheel rotates synchronously, and the punching shaft does not move. Under the action of the punching shaft, the burrs remaining at the injection port can be cleaned, making the injection port of the wind wheel smoother, thereby improving the punching effect. When the punching is completely completed, the turntable rotates one station again, and the next rotating seat rotates to the punching station to wait for punching.

[0021] In this structure, a pair of chucks are provided on each rotating disk to clamp the impeller, which can improve the overall stamping effect and facilitate deburring of the injection port of the impeller.

[0022] During the stamping process, when the rotating seat rotates to the unloading position, the pair of impellers on the rotating seat have completed the stamping. The chuck on the rotating seat releases the impellers, and the corresponding transfer assembly transfers the two impellers to the belt unloading platform to complete the unloading. When the rotating seat rotates to the loading station, the rotating seat is in an unloaded state, and another transfer assembly moves the impellers on the belt loading platform toward the rotating seat. After the impellers are transferred to the chuck on it, the chuck clamps them.

[0023] As a preferred structure, Figure 2 The linkage mechanism includes a base 12, a slide 13 is provided on the base 12, a connecting shaft 14 and a drive motor 15 are respectively provided for rotation inside and outside the slide 13, a driven wheel 16 is provided above the connecting shaft 14, and a driving wheel 17 is provided below the connecting shaft, a driving wheel 18 is provided on the driving shaft of the driving motor 15, and a transmission belt 20 is sleeved between the driving wheel 18 and the driven wheel 16, a sliding cylinder 19 is provided on the base 12, and a connecting rod 201 is provided on the driving shaft 191 of the sliding cylinder 19, which passes through the corresponding position of the slide and forms a baffle 21, a spring 22 is provided on the connecting rod 201 between the slide 13 and the driving shaft 191, and the driving shaft is thicker than the connecting rod.

[0024] When the rotating seat rotates to the punching station and the punching shaft completes the punching action on the impeller, the punching shaft is still in contact with the impeller. Then the linkage mechanism drives the two rotating seats to rotate. During this process, the punching shaft can remove the burrs remaining on the injection port.

[0025] Specifically, a sliding cylinder drives the slide a short distance toward the rotating table, causing the drive wheel to move toward the corresponding two interlocking wheels, positioned between them. When the drive wheel and the interlocking wheels come into contact, the drive motor drives the driving wheel, which in turn rotates under the influence of the transmission belt. The drive wheel drives the two interlocking wheels, which in turn rotate the two rotating seats synchronously, and thus the two intermediate wheels.

[0026] When the sliding cylinder drives the slide to slide a certain distance, the spring is gradually compressed during this process. When the spring is fully compressed, the driving wheel and the linkage wheel come into conflict. Under the preload of the spring, the linkage wheel can rotate more stably.

[0027] As a specific structure, such as Figure 3 The belt loading platform 3 is provided with two pairs of guide plates 23, and a loading channel is formed between the same pair of guide plates 23. A receiving platform 24 is provided at the tail of the belt loading platform 3, and a material guide groove 25 is formed on the side wall of the receiving platform 24 corresponding to the loading channel, and a drop opening 26 is opened at the bottom of the receiving platform 24 corresponding to the material guide groove 25.

[0028] In the above structure, a loading channel is formed between the same pair of guide plates, and each loading channel can be used to transport the blower wheel. The loading channel transports the blower wheel toward the receiving table one by one and in an orderly manner until the blower wheel passes through the guide groove on the same side and falls into the corresponding drop port. At this time, the corresponding transfer assembly can transfer the two blower wheels toward the rotating table.

[0029] The material transfer assembly 5 includes a material transfer platform 51, and sliding sleeves 52 are provided at the four corners of the material transfer platform 51. A sliding rod 53 is inserted into each sliding sleeve 52, and a top seat 54 is provided on the top of the sliding rod 53. A rotating cylinder 55 is provided on the top seat 54, and a driving shaft of the rotating cylinder 55 is provided with a pair of clamping hands 56. A lifting cylinder 57 is provided upward on the material transfer platform 51, and the driving shaft of the lifting cylinder 57 is connected to the top seat 54.

[0030] When using the corresponding material transfer assembly to transfer the air wheel in the blanking port to the chuck in the loading station and in an unloaded state, first the two clamping hands clamp the air wheel, then the lifting cylinder drives the top seat to move upward a short distance, and the air wheel moves away from the blanking port. The rotating cylinder drives the clamping hands to rotate toward the loading station. After rotating into place, the clamping hands move downward until the air wheel falls into the chuck and is clamped by it.

[0031] In addition, if Figure 2 The bottom surface of the rotary table 2 is provided with a circle of bottom blocks 27, and the machine table 1 is provided with a support seat 28 corresponding to the bottom blocks 27. The top of the support seat 28 is provided with a support wheel 29 for rotation, and the support wheel 29 supports the bottom blocks 27. When the rotary table rotates one station, the rotary table stops rotating, and the bottom blocks are re-supported by the corresponding support wheels, which can improve the stability of the stamping mechanism during stamping.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
