DETAILED DESCRIPTION

[0022] The present invention is described in detail below in conjunction with specific embodiments.

[0023] In the present utility model, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0024] like Figures 2 to 8 The utility model provides a gripping robot for taking out a steering wheel casting, comprising a base 1, a gripping robot 2 is mounted on the base 1, a steering wheel gripping assembly 3 is mounted on the gripping robot 2, the steering wheel gripping assembly 3 comprises a gripping frame 31, a positioning probe 32, an auxiliary driving member 33 and an auxiliary clamp 34, the gripping frame 31 is fixedly mounted on the gripping robot 2, the positioning probe 32 is mounted on the gripping frame 31, the positioning probe 32 is used to probe into the center of the steering wheel casting and resist the steering wheel casting; the auxiliary driving member 33 and the auxiliary clamp 34 are both mounted on the gripping frame 31, and the auxiliary clamp 34 can slide on the gripping frame 31, and the auxiliary clamp 34 can clamp the pouring port of the steering wheel casting under the drive of the auxiliary driving member 33.

[0025] In this embodiment, a claw assembly is provided on the clamping frame 31 near the positioning probe 32, and the claw assembly includes a claw sleeve 35 and a claw driving member 38. The claw driving member 38 is fixedly mounted on the clamping frame 31, and the claw driving member 38 is used to drive the claw sleeves 35 to move closer to or away from each other.

[0026] In this embodiment, a support pad 37 is provided near the positioning probe 32 , and the support pad 37 is fixedly mounted on the claw driving member 38 .

[0027] In this embodiment, a groove 36 is provided on the claw sleeve 35 and is matched with the bridge arm 43 of the steering wheel casting.

[0028] Through the above design scheme, when the steering wheel casting needs to be taken out of the furnace, the positioning probe 32 is inserted into the bearing seat mounting portion 41 for preliminary positioning, and then the auxiliary clamp 34 is extended to press against the casting port 42. Since there is an inclined surface at the casting port 42, the auxiliary clamp 34 will gradually press against the steering wheel casting during the extension process until the auxiliary clamp 34 cooperates with the positioning probe 32 to clamp the steering wheel casting.

[0029] Through the above design, the claw sleeve 35 can clamp the steering wheel casting to prevent it from falling; when the positioning probe 32 and the auxiliary clamp 34 clamp the steering wheel casting from the mold, the positioning probe 32 cooperates with the auxiliary clamp 34 to retract the steering wheel casting a short distance so that the groove 36 can be aligned with the steering wheel casting. As the claw sleeve 35 shrinks, the steering wheel casting will be clamped in the groove 36 to fully clamp it, and then the positioning probe 32 and the auxiliary clamp 34 are retracted to avoid long-term work damage to the positioning probe 32 and the auxiliary clamp 34. The support pad 37 can play a positioning role, so that the steering wheel casting can be aligned with the groove 36.

[0030] In this embodiment, a side end clamping assembly 39 is provided on the clamping frame 31, and the side end clamping assembly 39 includes a side end clamping driving member 391 and a side end caliper 392. The side end clamping driving member 391 is installed on the clamping frame 31, and the side end clamping driving member 391 is used to drive the side end calipers 392 to move closer to or away from each other.

[0031] Through the above design scheme, the side caliper 392 can clamp the outer ring 44 of the steering wheel casting when necessary. Since clamping the outer ring 44 will cause uneven force on the steering wheel casting when it is out of the furnace and thus affect the quality of the steering wheel casting, the side caliper 392 is only suitable for working when the auxiliary clamp 34 and the positioning probe 32 have difficulty clamping the steering wheel casting when an accident occurs to the steering wheel casting, ensuring that defective products can be clamped out of the mold in the event of an accident.

[0032] In this embodiment, the auxiliary clamp 34 includes a gear set, an extension drive member 344 and a washer 345. The gear set includes a transverse rack 341, a longitudinal rack 343 and a bridging gear 342. The bridging gear 342 is hinged on the clamping frame 31. The auxiliary drive member 33 is used to drive the transverse rack 341 to move horizontally. The transverse rack 341 drives the longitudinal rack 343 to move vertically through the bridging gear 342. The extension drive member 344 is installed on the longitudinal rack 343. The extension drive member 344 is used to clamp the washer 345. The washer 345 is used to resist the casting mouth of the steering wheel casting.

[0033] According to the above design, since the washer 345 needs to clamp the steering wheel casting, the temperature of the newly formed steering wheel casting is relatively high. After working for a certain period of time, the washer 345 will be worn and thus affect the clamping effect. When the washer 345 needs to be replaced, the extension drive member 344 contracts to make the washer 345 automatically fall off, and then automatically goes to the placement area under the control of the robot to replace the washer 345. In this embodiment, the transverse rack 341 and the longitudinal rack 343 can stably slide on the clamping frame 31 through the cooperation of the slider and the slide rail.

[0034] In this embodiment, the gripping robot 2 includes a turning platform 21, a swing arm 22, a transfer portion 23, a turning arm 24 and a connecting seat 25 which are connected in sequence. The turning platform 21 is installed on the base 1, and the connecting seat 25 is connected to the clamping frame 31.

[0035] The utility model provides a gripping robot for taking out a steering wheel casting. Compared with the prior art, when gripping a formed steering wheel casting, a positioning probe 32 extends into a circular hole at the center of the steering wheel casting, and can also hold the steering wheel casting while positioning, and then cooperates with an auxiliary clamp 34 to take the steering wheel casting out of the mold; after taking out the steering wheel casting, the positioning probe 32 and the auxiliary clamp 34 drive the steering wheel casting back a short distance so that the steering wheel casting is aligned with the groove 36, so that the claw sleeve 35 can firmly clamp the steering wheel casting.

[0036] In the absence of conflict, the above-mentioned embodiments and features of the embodiments may be combined with each other.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
