Description

Technical Field

[0001] The utility model relates to the technical field of bit production and processing, and particularly relates to a bit feeding device. Background Art

[0002] A bit usually refers to a screwdriver head installed on an electric drill or a hammer drill for screwing or unscrewing screws, also known as an electric screwdriver, which is used for tightening or loosening screws and belongs to a small electric tool. The types of bits include flat head, cross head, Phillips head, star head, square head, hex head, Y head, etc. Among them, flat head and cross head are the most commonly used types. Although hex head is not commonly used, it is often used in occasions where multi-angle force is required. Bits are widely used, including engineering, machinery, household appliance maintenance, production line operations, etc. The high-strength bit has the characteristics of high hardness and strong magnetism, and can easily pick up screws and extend the service life.

[0003] The main body of the bit is in a hexagonal head structure, and after processing, the corresponding specifications will be marked on one side of its main body. When the bit is placed in the corresponding position of the bit box, the marked position will also face upward for the user to use. However, due to the hexagonal head structure of the main body of the bit, during the feeding process, the marked positions on the main body of the bit are disordered, and it is impossible to make all the marked positions face upward, resulting in the bit being unable to be quickly placed in the bit box. It is necessary to flip the bit to make the marked position face upward before use, which is time-consuming and laborious, and greatly reduces the efficiency of bit tray loading.

[0004] Therefore, it is very necessary to improve the existing technology. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the utility model provides a bit feeding device, which has the effects of simple structure. When there is no bit with the mark facing upward in the storage box, the bits in the storage box are flipped by vibration, so that the marks of some bits face upward for the required bit tray loading, effectively improving the efficiency of bit tray loading.

[0006] To achieve the above object, the utility model provides the following technical solution: a bit feeding device, including a device body, characterized in that: the device body includes a bit flipping mechanism and a number of bit feeding mechanisms adapted to the bit flipping mechanism. The bit flipping mechanism includes a flexible vibrating disk and a number of bit storage boxes adapted to the flexible vibrating disk. The bit storage box is integrally arranged in a rectangular structure, and a storage groove adapted to it is opened on the bit storage box. Different specifications of marked bits are stored in each bit storage box, and the bits in the bit storage box are flipped by the up and down vibration of the flexible vibrating disk below it.

[0007] By adopting the above technical solution, when the bit is being placed on the bit tray and there are no bits with the mark facing up in the bit storage box, the flexible vibrating disk vibrates up and down to flip the bits in the bit storage box. Since the vibration can only flip some of the bits to make the mark face up, the number of bits in the bit storage box cannot be too small, and the bit replenishing mechanism replenishes the bits in a timely manner.

[0008] The present utility model is further configured as follows: The flexible vibrating disk includes a vibrating bottom box and a number of vibrating structures adapted to the bit storage box. The vibrating assembly includes a vibrating panel and vibrating motors located on the front and rear sides of the vibrating panel. The vibrating motors are connected to the vibrating panel through motor springs. A locking cylinder adapted to the vibrating motor is further provided on one side of the vibrating motor. The piston rod of the locking cylinder is fixedly connected to the vibrating panel. The locking cylinder and the vibrating motor are respectively fixedly connected to the vibrating bottom box through a cylinder mounting block and a motor mounting block. A suitable control circuit board and a small air pump are also provided in the vibrating bottom box. The small air pump is connected to the locking cylinder through an air delivery hose.

[0009] By adopting the above technical solution, the vibrating motor, the motor spring and the locking cylinder cooperate with each other to ensure that the bits in the bit storage box can vibrate up and down to achieve the flipping effect, and at the same time avoid the bits being vibrated out of the bit storage box due to excessive up and down vibration amplitude, ensuring the smooth progress of bit placement on the tray.

[0010] The present utility model is further configured as follows: The bit replenishing mechanism includes a linear feeder and a bit magazine adapted to the linear feeder. The top of the linear feeder is fixedly connected to the bit magazine through a magazine connecting plate. The cross-section of the bit magazine is arranged in an L-shaped structure. A bit feeding port adapted to the bit storage box is opened on one side of the bit magazine. The bit feeding port adopts an arc transition slanting downwards. A magazine baffle is further provided on one side of the bit magazine close to the bit feeding port. The magazine baffle and the bottom of the bit magazine form a bit feeding groove. The height of the bit feeding groove is greater than the height of one bit and less than the height of two bits.

[0011] By adopting the above technical solution, when the number of bits in the bit storage box is too small, the linear feeder drives the bit magazine to vibrate back and forth. The bits in the bit magazine vibrate out from the bit feeding groove and fall into the bit storage box to ensure the number of bits inside. The height of the bit feeding groove being greater than the height of one bit and less than the height of two bits can prevent too many bits from vibrating into the bit storage box at one time in the bit magazine, thus affecting the flipping effect of the bits in the bit storage box and further affecting the bit placement effect.

[0012] The present utility model is further configured as follows: A bin support adapted to the bin baffle is fixedly provided in the bit bin. The bin support and the bin baffle are fixedly connected to each other by adjusting bolts. Baffle mounting holes and baffle limiting grooves adapted to the adjusting bolts are respectively provided on the bin support and the bin baffle, and the baffle limiting groove is arranged in a vertical long strip structure.

[0013] By adopting the above technical solution, the height of the bit feeding chute is adjusted by the cooperation of the adjusting bolt and the bin baffle to adapt to bits of different specifications and models for replenishing materials.

[0014] The present utility model is further configured as follows: A bin support adapted to the bin baffle is fixedly provided in the bit bin. A baffle chute adapted to the bin baffle is provided on the bin support. An adjusting motor adapted thereto is also fixedly connected to the bin support. A lifting structure is arranged between the bin baffle and the adjusting motor. The lifting structure includes a lower lifting rod and an upper lifting rod sleeved outside the lower lifting rod. The upper lifting rod and the lower lifting rod are movably connected to each other in a threaded manner. The upper lifting rod and the lower lifting rod are respectively fixedly connected to the upper end of the hopper baffle and the output shaft of the adjusting motor. A baffle lug adapted to the upper lifting rod is fixedly provided at the upper end of the hopper baffle.

[0015] By adopting the above technical solution, the forward and reverse rotation of the adjusting motor drives the lifting structure to expand and contract to control the lifting of the bin baffle, so as to quickly adjust the height of the bit feeding chute to adapt to bits of different specifications and models for replenishing materials and improve work efficiency.

[0016] The present utility model is further configured as follows: The device body is also provided with a controller adapted to the bit flipping mechanism and the bit replenishing mechanism.

[0017] By adopting the above technical solution, the controller is used to control the bit flipping mechanism to flip the bit and the bit replenishing mechanism to replenish the bit to ensure the smooth progress of bit tray loading.

[0018] In summary, the present utility model has the following beneficial effects:

[0019] 1. When the bits are being loaded into the bit box and there are no bits with the mark facing up in the bit storage box, the flexible vibrating disk vibrates up and down to flip the bits in the bit storage box. Since only some bits can be flipped to face up by vibration, the number of bits in the bit storage box cannot be too small, and the bit replenishing mechanism replenishes the bits in a timely manner.

[0020] 2. The vibration motor, motor spring and locking cylinder cooperate with each other to ensure that the bits in the bit storage box can vibrate up and down to achieve the flipping effect, and avoid excessive up and down vibration amplitude causing the bits to vibrate out of the bit storage box, thereby ensuring the smooth bit placement; the height of the bit feeding trough is greater than the height of one bit and less than the height of two bits, which can avoid too many bits in the bit hopper from vibrating at one time and entering the bit storage box, thereby affecting the flipping effect of the bits in the bit storage box, and then affecting the bit placement effect.

DETAILED DESCRIPTION

[0029] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0030] Example 1 discloses a bit feeding device. As shown in Figures 1 to 5 the figure, it includes a device body, which includes a bit flipping mechanism 1 and several bit replenishing mechanisms 2 adapted to the bit flipping mechanism 1. The bit flipping mechanism 1 includes a flexible vibrating disk 11 and several bit storage boxes 12 adapted to the flexible vibrating disk 11. The bit storage box 12 is integrally arranged in a rectangular structure, and a storage groove 121 adapted to it is opened on the bit storage box 12. Different specifications of marked bits are stored in each bit storage box 12. When the bits are being placed on the bit tray and there are no bits with the mark facing up in the bit storage box 12, the flexible vibrating disk 11 below it can vibrate up and down to flip the bits in the bit storage box 12. Since the main body of the bit is arranged in a hexagonal head structure, there is a probability problem during the flipping process, and it is impossible and cannot make all the marks of the bits in the bit storage box 12 face up through one vibration. Only some bits can be flipped to make the marks face up for the bit placement on the tray. Therefore, the number of bits in the bit storage box 12 cannot be too small, and the bit replenishing mechanism 2 needs to replenish the bits in time. During the up and down vibration of the flexible vibrating disk 11, the vibration amplitude is small to prevent the bits from vibrating out of the bit storage box 12.

[0031] The flexible vibrating disk 11 includes a vibrating bottom box 111 and several vibrating structures 112 adapted to the bit storage box 12. The vibrating assembly includes a vibrating panel 112a and vibrating motors 112b located on the front and back sides of the vibrating panel 112a. The vibrating motors 112b are connected to the vibrating panel 112a through motor springs 112c. A locking cylinder 112d adapted to it is also arranged on one side of the vibrating motor 112b. The piston rod of the locking cylinder 112d is fixedly connected to the vibrating panel 112a. The locking cylinder 112d and the vibrating motor 112b are respectively fixedly connected to the vibrating bottom box 111 through a cylinder mounting block 112e and a motor mounting block 112f. The bit storage box 12 generates up and down vibration through the vibrating assembly to drive the bits inside it to flip. At the same time, the vibrating motor 112b, the motor spring 112c, and the locking cylinder 112d cooperate with each other to ensure that the bits in the bit storage box 12 can vibrate up and down to achieve the flipping effect, and also prevent the bits from vibrating out of the bit storage box 12 due to excessive up and down vibration amplitude, ensuring the smooth progress of bit placement on the tray.

[0032] A suitable control circuit board 113 and a small air pump 114 are also arranged in the vibrating bottom box 111. The small air pump 114 is connected to the locking cylinder 112d through an air delivery hose. The control circuit board 113 and the small air pump 114 cooperate with each other to control the vibrating assembly to vibrate up and down, so that the bits in the bit storage box 12 achieve the flipping effect.

[0033] The batch head feeding mechanism 2 includes a linear feeder 21 and a batch head silo 22 matched with the linear feeder 21. The top of the linear feeder 21 is fixedly connected to the batch head silo 22 by setting a silo connecting plate 211. The cross section of the batch head silo 22 is L-shaped. A batch head feeding port 221 matched with the batch head storage box 12 is provided on one side of the batch head silo 22. A downward slanting arc transition is adopted at the batch head discharge port. A silo baffle 222 is also provided on the side of the batch head silo 22 near the batch head discharge port. The silo baffle 222 and the bottom of the batch head silo 22 form a batch head feeding trough 223. The batch head feeding trough The height of 223 is greater than the height of one batch head and less than the height of two batch heads. When the number of batch heads in the batch head storage box 12 is too small, the linear feeder 21 drives the batch head bin 22 to vibrate back and forth, and the batch heads in the batch head bin 22 are vibrated out from the batch head feeding trough 223 and fall into the batch head storage box 12 to ensure the number of batch heads inside it. The height of the batch head feeding trough 223 is greater than the height of one batch head and less than the height of two batch heads, which can prevent too many batch heads in the batch head bin 22 from vibrating at one time and entering the batch head storage box 12, thereby affecting the flipping effect of the batch heads in the batch head storage box 12, and then affecting the effect of the batch head display.

[0034] A silo bracket 224 matched with the silo baffle 222 is fixedly provided in the batch head silo 22. The silo bracket 224 and the silo baffle 222 are fixedly connected to each other by setting an adjusting bolt, and the silo bracket 224 and the silo baffle 222 are respectively provided with a baffle mounting hole 224a and a baffle limiting groove 222a matched with the adjusting bolt. The baffle limiting groove 222a is arranged in a vertical long strip structure. The height of the batch head feeding trough 223 is adjusted by adjusting the bolt and the silo baffle 222 to adapt to the batch heads of different specifications and models for refilling.

[0035] The device body is also provided with a controller (not shown in the drawings) adapted to the bit flipping mechanism 1 and the bit feeding mechanism 2. The controller can be manually controlled or automatically controlled to control the bit flipping mechanism 1 to flip the bit and the bit feeding mechanism 2 to feed.

[0036] The working process is as follows: when there are no batch heads with marks facing upwards in the batch head storage box 12 during the process of arranging batch heads, the batch head storage box 12 generates up and down vibrations through the vibration component to drive the batch heads inside it to flip and vibrate up and down, so that the batch heads in the batch head storage box 12 are flipped. Although it is not possible to make all the batch heads marked upwards in the batch head storage box 12, some batch heads can be flipped so that the marks face upwards to meet the needs of arranging batch heads. At the same time, when the number of batch heads in the batch head storage box 12 is small, the linear feeder 21 drives the batch head hopper 22 to vibrate back and forth, and the batch heads in the batch head hopper 22 are vibrated out of the batch head feeding trough 223 and fall into the batch head storage box 12 to ensure the number of batch heads inside it and ensure that the batch heads are smoothly arranged on the plate.

[0037] Embodiment 2. The difference between this embodiment and Embodiment 1 is that, as Figure 6 and 7 shown, a bin support 224 adapted to the bin baffle 222 is fixedly installed in the bit bin 22. A baffle chute 224b adapted to the bin baffle 222 is provided on the bin support 224. An adjusting motor 224c adapted thereto is also fixedly connected to the bin support 224. A lifting structure 225 is provided between the bin baffle 222 and the adjusting motor 224c. The lifting structure 225 includes a lower lifting rod 225b and an upper lifting rod 225a sleeved outside the lower lifting rod 225b. The upper lifting rod 225a and the lower lifting rod 225b are movably connected to each other in a threaded manner, and the upper lifting rod and the lower lifting rod 225b are respectively fixedly connected to the upper end of the hopper baffle and the output shaft of the adjusting motor 224c. A baffle lug 222b adapted to the upper lifting rod 225a is fixedly installed at the upper end of the hopper baffle. By driving the lifting structure 225 to expand and contract through the forward and reverse rotation of the adjusting motor 224c, the lifting of the bin baffle 222 is controlled, so as to adjust the height of the bit feeding chute 223 to adapt to bits of different specifications and models for replenishing materials, avoiding the tediousness of manually adjusting the adjusting screw and the bin baffle 222 in Embodiment 1 and improving work efficiency.

[0038] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention shall be included in the protection scope of the present invention.
