Description

Technical field:

[0001] The utility model relates to the technical field related to motor processing equipment, and more specifically to a conveying frame for a rotating shaft of a roller motor. Background technology:

[0002] Roller motors are specifically designed for demanding applications such as high torque loads, high ambient temperatures, humidity, and dust. Roller motors are low-speed motors designed for direct connection to the rollers. A wide range of pole numbers and frequencies means that a gearbox is often not required.

[0003] The spindle is long and generally requires multiple processing steps. During the processing, it is necessary to place the spindle in a transport vehicle after the previous step is completed. After a certain amount of spindles are placed in the transport vehicle, they are manually pushed to the processing equipment of the subsequent processing steps, and then gradually taken out for processing. This is inefficient and has poor results.

[0004] Moreover, some existing methods use automated equipment, which uses continuous automatic conveying equipment to transport the parts completed by the previous equipment to the next process, wherein loading and unloading are both operated by robots to achieve continuous processing. In the existing spindle processing process, the equipment that needs to be processed in each process is generally arranged in front and back. The spindle processed by the previous equipment can be moved to the next equipment for processing in the next process. Therefore, a transmission device will be set between the two.

The screw portion of the fixing bolt is inserted into the corresponding elongated through groove and screwed to the corresponding fixed connecting plate 111. The adjusting connecting block 31 is clamped between the corresponding fixed connecting plate 111 and the bottom surface of the rotating part of the bolt.

[0043] Connecting beams 19 extending frontward and rearward are provided between the left, middle and right parts of the two side beams 11. The front and rear ends of the connecting beams 19 are welded and fixed to the inner side walls of the side beams 11. A horizontal connecting plate 191 is fixed to the top surface of the connecting beam 19. Adjustment plates 192 are placed at the front and rear of the middle part of the top surface of the horizontal connecting plate 191. A plurality of elongated adjustment through holes are formed on the rear part of the adjustment plate 192. The screw parts of the fixing bolts are inserted into the corresponding elongated adjustment through holes and screwed to the corresponding horizontal connecting plates 191. The adjustment plates 192 are clamped between the rotating part of the fixing bolts and the top surface of the horizontal connecting plate 191.

[0044] A support block 193 is formed or fixed on the front top surface of the adjustment plate 192, and a through groove is formed in the middle of the top surface of the support block 193. Multiple transmission rollers 194 are in the through groove. The two ends of the pin shaft fixed in the middle of the transmission roller 194 extend out of the front and rear ends of the transmission roller 194 and are inserted into the through holes formed on the inner side walls on the front and rear sides of the through groove. The top surface of the transmission roller 194 is higher than the top surface of the support block 193, and the bottom surface of the upper chain part of the chain 14 is pressed against the top surface of the corresponding transmission roller 194.

[0045] When this embodiment is in use, the robot of the previous process places the processed spindle into the triangular slot 24 formed in the middle of the top surface of the vertical plate of the two movable support seats 23 (the push rod of the lifting cylinder 20 is pushed upward at this time, so that the top of the two vertical plates is higher than the top surface of the chain 14). At this time, the spindle is inserted into the two triangular slots 24 and rests on the inner side wall of the corresponding triangular slot 24. Then, the push rod of the lifting cylinder 20 retracts (it is controlled by the control host, which can be used in the previous process to place the processed spindle into the triangular slot 24). 2 to 5 seconds after the main shaft is placed, the push rod of the lifting cylinder 20 is automatically retracted). During retraction, the main shaft will lean against the top surface of the upper chain part of the two chains 14, and the reduction motor 17 will be operated to transport it backward. Then, the push rod of the lifting cylinder 20 is pushed out and returned to its position (it is generally lifted and returned to its position about 5 seconds after retraction). During the conveying process, the bottom surface of the upper chain part of the chain 14 is pressed against the top surface of the corresponding transmission roller 194, so that it can still operate normally after being pressed against the main shaft to achieve conveying.

[0046] Until it is pressed against the upper left wall of the right vertical plate and limited, at this time, the sensing end of the proximity switch 4 senses the main shaft, indicating that it has been delivered to the position. At this time, the host computer controls the subsequent manipulator to grab it and carry out subsequent processing, which is very convenient. When it is transported on the chain 14, there is a gap between the two adjacent main shafts to ensure that after the previous main shaft is grabbed, the next main shaft will not be transported over, so as not to affect the normal grabbing of the previous main shaft.

[0047] In this embodiment, when the main shaft is being transported, the two limiting beams 30 are used to limit the main shaft so as to ensure normal transportation.

[0048] By loosening the corresponding fixing bolts, the positions of the two limiting beams 30 can be moved to meet the position limits of the front and rear ends when conveying spindles of different lengths;

[0049] By loosening the corresponding bolts, the front and rear positions of the adjustment plate 192 can be adjusted to ensure that the bottom surface of the upper chain portion of the chain 14 is pressed against the top surface of the corresponding transmission roller 194, and then the bolts can be tightened.

[0050] The positions of the two movable support seats 23 in this embodiment can also be adjusted. It only requires holding the pressing block 216 and moving the telescopic rod 215 to the right, so that the connecting plate 217 is pressed and adsorbed on the annular permanent magnet part 2. At this time, the return spring 1 is compressed and the positioning clamping part 218 is moved out of the corresponding positioning groove. At this time, manually turning the hand wheel 213 causes the adjusting screw 212 to rotate, so that the two movable support seats 23 can be moved closer or farther away, meeting the distance position adjustment between the vertical plates of the two movable support seats 23 and meeting the support placement requirements of different spindles. For example, some spindles have a large diameter portion in the middle, which needs to be between the two vertical plates, otherwise it will be in the triangular slot 24 of the vertical plate. Due to its large diameter, it cannot be completely in the triangular slot 24, and it may not be able to be placed steadily when placed, thereby falling from the vertical plate. Since the length of the large diameter portion in the middle of spindles of different models is different, it is necessary to adjust the position of the two movable support seats 23.

[0051] After the adjustment is completed, the pressing block 216 is pushed to separate the connecting plate 217 from the annular permanent magnet part 2. At this time, the positioning clamping part 218 can be inserted into the corresponding positioning groove through the action of the reset spring 1 to achieve positioning, so that the handwheel 213 cannot be rotated. When its positioning clamping part 218 cannot be inserted into the corresponding positioning groove, it is necessary to manually rotate the handwheel 213 to move the nearest positioning groove into place so that the positioning clamping part 218 is inserted into the positioning groove. The fine-tuning at this time does not affect the distance between the two vertical plates, that is, the fine-tuning at this time does not change the distance between the two vertical plates much, and does not affect its normal use.
