Description

Technical Field

[0001] The utility model belongs to the field of feeding devices, and in particular relates to a continuous feeding device used for chamfering of bolts. Background Art

[0002] Bolts are a common fastener. In order to facilitate the connection between the bolt and the nut after the bolt thread is processed, the bolts generally need to be chamfered. Smaller bolts can be processed directly by cold heading when the bolts are formed, while larger bolts are generally made of thicker steel bars. A bolt chamfering machine is required for chamfering. When using a bolt chamfering machine to process bolts, manual loading and unloading are generally performed, resulting in low work efficiency.

[0003] A Chinese patent with announcement number CN216858247U discloses a continuous feeding device for bolt chamfering processing, including a bolt chamfering machine, the bolt chamfering machine including a three-jaw chuck and a tool holder, a positioning column is installed at the upper end of the front side of the three-jaw chuck, an inclined collecting channel is installed at the front side of the bolt chamfering machine, a pushing mechanism is installed at the rear side of the bolt chamfering machine, the pushing mechanism includes a pushing channel fixedly installed at the upper end of the rear side of the bolt chamfering machine, a pushing column is installed in the pushing channel, a loading mechanism is installed at the rear side of the bolt chamfering machine, the loading mechanism includes a holding box fixedly installed on one side of the upper end of the bolt chamfering machine, an inclined guide plate is installed between the holding box and the pushing channel, and a lifting platform is installed on the holding box. The beneficial effect of the present invention is that this device uses a storage box to place bolts, and more bolts can be stacked in the storage box, occupying a smaller area, and can realize automatic continuous loading, thereby improving work efficiency. However, the continuous feeding device for bolt chamfering processing in this application can only lift one bolt out at a time through the lifting platform, and cannot continuously discharge the material, which affects the loading effect.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] See also Figure 1-3 As shown, in this embodiment, a continuous feeding device for bolt chamfering processing is provided, including two mounting plates 1, a raw material box 2 is provided on the upper side of the two mounting plates 1, a belt conveyor 3 is provided between the two mounting plates 1, and a plurality of limit grooves 4 are arranged in an array along the transmission direction on the belt conveyor 3, a blanking port 5 is provided on the bottom surface of the raw material box 2, and a discharge port 6 is provided on the side of the raw material box 2, and the blanking port 5 is connected to the discharge port 6.

[0024] By placing the bolts neatly in the raw material box 2 and separating the two adjacent bolts in the horizontal direction by the dividing plate 7, the probability of horizontal misalignment of the bolts is reduced, and the placement efficiency is improved. The bolts fall into the limiting groove 4 on the upper side of the belt conveyor 3 through the drop port 5, and then the belt conveyor 3 continuously brings the bolts out of the raw material box 2 through the discharge port 6 in sequence, which facilitates continuous loading and improves the feeding efficiency.

[0025] In this embodiment, the bottom surface height of the raw material box 2 gradually decreases from the first end to the second end, and the drop port 5 and the discharge port 6 are arranged at the second end of the bottom surface of the raw material box 2, so that the bolts can pass through the drop port 5 and fall into the limiting groove 4 on the upper side of the belt conveyor 3, and then the bolts are continuously brought out of the raw material box 2 through the discharge port 6 through the belt conveyor 3, so as to facilitate continuous loading.

[0026] In this embodiment, there are multiple dividing plates 7 arrayed in the raw material box 2, with a spacing between adjacent dividing plates 7, and a spacing between the dividing plates 7 and the bottom surface of the inner wall of the raw material box 2, so that the lower part of the bolt falls in the limiting groove 4 and the upper part is in the blanking port 5. Two limiting plates 8 are slidably fitted in the raw material box 2, and a through hole 9 corresponding to the dividing plate 7 is provided on one side of the limiting plate 8. A U-shaped frame 10 corresponding to the limiting plate 8 is slidably fitted on one side of the raw material box 2. The U-shaped frame 10 extends into the raw material box 2 and is fixedly connected to the limiting plate 8 at one end. The side of the raw material box 2 is rotatably fitted with an adjusting handle bolt 11 threadedly fitted with the U-shaped frame 10, so that the U-shaped frame 10 can be driven to slide by adjusting the handle bolt 11, and then the limiting plate 8 can be driven to slide, so as to adjust the spacing between the two limiting plates 8 and to adapt to bolts of different lengths to be neatly placed in the raw material box 2.

[0027] In this embodiment, a bearing 12 corresponding to the adjusting handle bolt 11 is embedded in the side of the raw material box 2, and one end of the adjusting handle bolt 11 is provided with a smooth curved surface. One end of the adjusting handle bolt 11 is fixed in the bearing 12, so that the stability of the rotation of the adjusting handle bolt 11 can be improved through the bearing 12, and the stability of the sliding of the limit plate 8 driven by the adjusting handle bolt 11 can be improved.

[0028] In this embodiment, a transmission rod 13 is provided between the two adjustment handle bolts 11, which passes through the raw material box 2 and one of the partition plates 7. The thread directions of the two adjustment handle bolts 11 are opposite, so that the two adjustment handle bolts 11 can rotate synchronously by setting the transmission rod 13, thereby improving the convenience of adjusting the distance between the two limit plates 8.

[0029] Working principle: Place the bolts neatly in the raw material box 2, and separate the two adjacent bolts in the horizontal direction by the dividing plate 7 to reduce the probability of horizontal dislocation of the bolts and improve the placement efficiency.

Turn the adjustment handle bolt 11 to drive the U-shaped frame 10 to slide, and then drive the limit plate 8 to slide, so as to adjust the distance between the two limit plates 8, so as to adapt to the bolts of different lengths to be neatly placed in the raw material box 2.
