[0024] A preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.

[0025] See also Figures 1 to 6 The present application provides a turntable drill bit processing transfer device, which is used for processing, testing and boxing transfer of drill bits. It includes a frame 1, on which a turntable 2 and a first driving assembly 3 for driving the turntable 2 to rotate are provided. The turntable 2 is provided with at least four material placement troughs 21 in a circular array. When the turntable 2 drives the material placement troughs 21 to rotate, each material placement trough 21 circulates and transports drill bits in sequence between the loading station A, the processing station B, the testing station C and the unloading station D; a loading mechanism 4 for continuously providing drill bits to the loading station A is provided on the side of the loading station A; and a lifting and unloading mechanism 5 for lifting the drill bits located at the unloading station D and collecting them into the transfer hopper 51 is provided on the unloading station D.

[0026] Specifically, the first drive assembly 3 uses a divider, which can maintain sufficient torque when rotating at a low speed to ensure that the turntable 2 does not swing and rotates smoothly. The turntable 2 is connected to the main shaft of the divider, and the turntable 2 drives the material trough 21 thereon to rotate synchronously. The material trough 21 on the turntable 2 can be set according to the number of production stations. The present embodiment has four material troughs 21 arranged along the radial direction of the turntable 2 and evenly spaced, and the width of the material trough 21 is consistent with the diameter of the drill shank. The other four material troughs 21 are respectively arranged corresponding to the loading station A, the processing station B, the inspection station C and the unloading station D. The rotation of the turntable 2 drives the material trough 21 to circulate in the above four stations, and when it rotates to the unloading station D, it is collected in the transfer hopper 51. That is, the divider uses a 90° divider, and when the drill bit is transported to the feeding station A through the feeding mechanism 4, one of the four feeding slots 21 docks with the feeding slot 11, and the feeding mechanism 4 transports the drill bit from the feeding slot 11 into the feeding slot 21. The processing station B and the inspection station C can be integrated by selecting corresponding equipment according to production needs, which will not be described in detail in this article.

[0027] Furthermore, the feeding mechanism 4 includes a feeding conveyor belt 41 arranged radially along the turntable 2, and a second driving assembly 42 driving the feeding conveyor belt 41 to rotate; when the feeding conveyor belt 41 rotates synchronously with the turntable 2, the drill bits on the feeding conveyor belt 41 can be transferred one by one to the material placement trough 21 located on the feeding station A. The feeding conveyor belt 41 is inclined at a certain angle to the horizontal plane, and a conveying trough 411 is provided on the upper end surface close to the feeding conveyor belt 41, and the width of the conveying trough 411 is slightly larger than the diameter of the drill bit shank. The angle between the feeding conveyor belt 41 and the horizontal plane is 30-45°.

[0028] Specifically, the angle between the feeding conveyor belt 41 and the horizontal plane is 30°. The feeding conveyor belt 41 is tilted so that the center of gravity of the drill bit is at an angle of 30° to the vertical direction. At the same time, the limit of the conveying trough 411 is used to ensure that the drill bit does not roll during the conveying process; the second drive component 42 uses a DD motor to ensure the stability of the conveying process. Each feeding trough 21 is docked with the feeding trough 11 at the feeding station A, so the feeding frequency of the feeding conveyor belt 41 is the same as the rotation frequency of the turntable 2, that is, after the turntable 2 drives the feeding trough 21 to rotate from the feeding station A to the processing station B, the feeding conveyor belt 41 conveys a drill bit to the feeding trough 21.

[0029] Furthermore, the lifting and unloading mechanism 5 also includes a lifting and loading assembly 52, a lifting and loading channel 53 and a swing self-resetting assembly 54. The lifting and loading assembly 52 is arranged below the frame 1, and is used to lift the drill bit in the material trough 21 located on the unloading station D upward to the transfer hopper 51; the lifting and loading channel 53 is arranged between the turntable 2 and the transfer hopper 51, and the lower end is connected to the material trough 21 located at the unloading station, and the upper end is connected to the feed port 511 of the transfer hopper 51; the swing self-resetting assembly 54 is arranged in the lifting and loading channel 53, and is used to prevent the drill bit placed in the transfer hopper 51 from falling. The lifting and loading assembly 52 includes a lifting cylinder 521 vertically arranged below the turntable 2, and a U-shaped push plate 522 connected to the end of the piston rod of the lifting cylinder 521, and a lifting channel 211 matching the U-shaped push plate 522 is opened at the bottom of the material trough 21.

[0030] Specifically, each material trough 21 has a lifting channel 211 at the bottom thereof that matches the U-shaped push plate 522. Therefore, the material trough 21 not only supports the drill bit placed therein, but also provides a channel for the end of the U-shaped push plate 522 to vertically pass through the material trough 21 and lift the drill bit in the material trough 21 upward. Among them, the U-shaped push plate 522, the material trough 21 located at the unloading station D, the lifting material channel 53, and the feed 511 of the transfer hopper 51 are all on the same vertical plane, and the material trough 21, the lifting material channel 53, and the feed 511 are consistent with the shank diameter and overall length of the drill bit.

[0031] Furthermore, a plurality of spaced limiting grooves 531 are provided on one side wall of the lifting and feeding channel 53, and the swing self-resetting assembly 54 comprises a swing arm 541, a hinge shaft 542, a reset spring 543 and a spring support block 544. The swing arm 541 is rotatably connected to the limiting groove 531 through the hinge shaft 542. The swing arm 541 is placed in the lifting and feeding channel 53. The side wall is a slope 5411 that tilts upward and outward from bottom to top, and a spring positioning block 5412 is provided on the upper part of the other side wall; the spring support block 544 is provided directly below the spring positioning block 5412, and the reset spring 543 is provided between the spring support block 544 and the spring positioning block 5412. The lower part of the transfer hopper 51 is provided with a feed port 511 that matches the drill bit, and an avoidance slot 512 for avoiding the swing arm 541.

[0032] Specifically, the movement process of the drill bit on the loading trough 21 located at the unloading station D is as follows: the lifting cylinder 521 drives the U-shaped pushing plate 522 to lift the drill bit upward through the lifting and feeding channel 53, and enter the transfer hopper 51 from the feeding port 511 of the transfer hopper 51. When the drill bit passes through the lifting and feeding channel 53, the swing arm 541 tilts toward the side of the reset spring 543 under the action of the upward lifting force, and the feeding port 511 of the transfer hopper 51 is opened, and the reset spring 543 is compressed by the force; when the drill bit enters the transfer hopper 51, the U-shaped pushing plate 522 falls back downward. At this time, the swing arm 541 is reset under the action of the elastic force of the reset spring 543, so that its top stops on the feeding port 511 of the transfer hopper 51, thereby preventing the drill bit in the transfer hopper 51 from falling.

[0033] To summarize, the turntable drill bit processing transfer device provided in the present application uses a turntable structure to transfer the drill bit in a rotating manner, and different processing equipment is arranged on the transfer path to process the drill bit. The structure is compact, and the transfer time is saved and the transfer efficiency is improved. The drill bit is lifted to the transfer silo for collection through jacking-type unloading for subsequent equipment processing. The structure is simple and the working reliability is high.
