Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an automatic nut feeding device. Background Art

[0002] Nuts are a kind of parts that must be used in all mechanical manufacturing and assembly. At present, nuts are generally loaded manually. When the operator needs to use a nut, he takes a nut from a pile of nuts, adjusts the position of the nut and transports it to the corresponding mold for the next assembly. This way of working is very wasteful of manpower and time, and the production efficiency is extremely low, which indirectly increases the production cost and does not conform to the scale, industrialization and automation of modern industry. Therefore, it is necessary to develop a device that can realize automatic nut loading, which is conducive to the development and progress of industrial automation. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned defects in the prior art and provide an automatic nut feeding device. The utility model realizes automatic feeding through a feeding component, positions and conveys the nuts through a dislocation component, and finally the first feeding component and the second feeding component cooperate to feed the nuts to the next process for processing, thereby realizing the automation of feeding, eliminating the need for manual auxiliary feeding, reducing labor costs, and improving production efficiency.

[0004] In order to achieve the above object, the utility model provides a nut automatic feeding device, comprising:

[0005] A feeding assembly, which is used for adjusting the direction of the nut and conveying the nut;

[0006] A rack, wherein a slide rail is provided on the rack;

[0007] A dislocation component slidably disposed on the slide rail, wherein the dislocation component is provided with a conveying channel matched with the nut, and the conveying channel is provided with a feed inlet, and the feed inlet is connected to the feeding component;

[0008] A first feeding assembly slidably disposed on the slide rail, wherein the first feeding assembly is provided with a push rod, the diameter of the push rod being smaller than the diameter of the inner hole of the nut, so that the push rod can penetrate into the inner hole of the nut;

[0009] A second feeding assembly is slidably arranged on the slide rail, and the second feeding assembly is arranged between the offset assembly and the first feeding assembly. The second feeding assembly is provided with a push rod, and the push rod is provided with a through hole for passing the push rod. The central axis of the push rod, the central axis of the push rod and the central axis of the conveying channel are all on the same horizontal line.

[0010] Furthermore, the dislocation component includes: a first slider connected to the slide rail, a dislocation seat fixedly arranged on the first slider, the conveying channel arranged on the dislocation seat, a staggered structure arranged on the dislocation seat, the staggered structure arranged on the conveying channel, a first guide shaft fixedly connected to one side of the dislocation seat, and a first guide stopper arranged on the other side of the first guide shaft away from the dislocation seat. The coordination of the first slider and the slide rail enables the dislocation component to move freely along the slide rail, and the staggered structure enables the nut to be positioned to ensure that only one nut can be input at a time, and the nut entering the conveying channel can be limited to prevent the nut from falling, thereby ensuring the stability of the feeding operation.

[0011] Furthermore, the side wing of the dislocation seat is fixedly connected with a dislocation connection seat, and the dislocation structure includes a dislocation block and a dislocation spring connected with the dislocation block. The dislocation seat is provided with a mounting hole penetrating the inner wall of the conveying channel, one end of the dislocation block is connected with the mounting hole and placed in the conveying channel, and the other end of the dislocation block away from the mounting hole is provided with a dislocation spring, and the dislocation spring is fixedly connected with the dislocation connection seat. The dislocation block can limit the nut entering the conveying channel so that the nut will not fall.

[0012] Furthermore, one end of the dislocation block is provided with an inclined guide portion and a top connection portion connected to the inclined guide portion, and an arc transition portion is provided between the inclined guide portion and the top connection portion, and the inclined guide portion is adjacent to the feed port. The provision of the inclined guide portion can better cooperate with the delivery of the push rod and the push rod, so that during the movement of the nut, the nut squeezes the inclined guide portion to retract it into the installation hole without blocking the main nut. The provision of the arc transition portion prevents the dislocation block from causing damage to the nut, and the transition is more natural.

[0013] Furthermore, the second feed assembly includes: a third slider slidably arranged on the slide rail, the third slider is estimated to have a second feed fixed seat, the push rod is fixedly connected to the second feed fixed seat, one side of the second feed fixed seat is connected to the first guide shaft through a sliding bearing, the other side of the second feed fixed seat is fixedly connected to the second guide shaft, and the second guide shaft is arranged on the other side away from the second feed fixed seat.

[0015] Furthermore, the end of the ejector rod away from the other end of the first feed fixing seat is a tapered structure, and the length of the ejector rod is greater than the push rod. The tapered structure enables the ejector rod to better penetrate the inner hole of the nut, and cooperate with the push rod to feed the nut; in particular, the ejector rod is longer than the push rod to form a length difference between the two, ensuring that the nut first penetrates the ejector rod and then is ejected by the push rod, thereby ensuring the stable operation of each process.

[0016] Furthermore, an auxiliary stopper is provided on one side of the frame, a slot is provided at the end of the auxiliary stopper, an auxiliary stopper is fixed to the side wing of the second feed fixing seat, the auxiliary stopper is provided with a stopper extending downward, and the movement position of the stopper is set on the axis of the slot. The cooperation of the auxiliary stopper and the auxiliary stopper can ensure that the second feed fixing seat will not deviate during the reciprocating process, ensure that it can maintain a straight line operation, and improve the overall stability.

[0017] Furthermore, the frame is also fixedly connected with a feed auxiliary seat, the feed auxiliary seat is provided with an auxiliary material channel, the auxiliary material channel and the conveying material channel are perpendicular to each other and the two are connected to each other, a positioning line is provided on the feed auxiliary seat, and tightening torsion bars are provided on both sides of the positioning line.

[0021] 2. The dislocation assembly can be used to limit and position the nuts entering the conveying channel, so that the nuts can be placed in the conveying channel without falling. In particular, the dislocation spring setting can enable the dislocation block to extend and retract between the mounting holes. After the first nut is conveyed, the dislocation block can be immediately reset to limit the second nut entering the channel, thereby preventing multiple nuts from entering the conveying channel at the same time and affecting the feeding operation.

[0022] 3.

Figure 8 As shown, the end of the push rod 41 away from the other end of the first feed fixing seat 44 is a conical structure 411. The setting of the conical structure 411 can make it easier for the push rod 41 to pass through the inner hole of the nut. The length of the push rod 41 is greater than that of the push rod 51.

[0045] The second feeding assembly 5 is slidably arranged on the slide rail 11, such as Fig. 9As shown, the second feeding assembly 5 is arranged between the dislocation assembly 3 and the first feeding assembly 4, the second feeding assembly 5 is provided with a push rod 51, the push rod 51 is provided with a through hole 511 for passing the push rod 41, the central axis of the push rod 51, the central axis of the push rod 41 and the central axis of the conveying channel 31 are all on the same horizontal line, specifically, the second feeding assembly 5 includes: a third sliding block 52 slidably arranged on the slide rail 11, the third sliding block 52 is estimated to have a second feeding fixed seat 53, the push rod 51 is fixedly connected to the second feeding fixed seat 53, and one side of the second feeding fixed seat 53 is provided with a sliding The movable bearing is connected to the first guide shaft 35, and a second guide shaft 54 ​​is fixedly connected to the other side of the second feed fixing seat 53.

The shape of the auxiliary channel 13 matches the nut. The positioning line 15 on the auxiliary channel 13 will perform a secondary screening of the direction of the nut. Since the auxiliary seat is vertically arranged above the offset seat 34, after the nut enters the auxiliary channel 13, it will fall into the conveying channel 31 along the auxiliary channel 13. When the first nut enters the conveying channel 31, the inclined guide part 361 on the offset block 36 will abut against the nut, so that it cannot The push cylinder 43 starts to push the second slide block 42, which will drive the first feed fixing seat 44 to slide forward. At the same time, the push rod 41 fixed to the first feed fixing seat 44 will also move forward. When the push rod 41 reaches the nut position, the end of the push rod 41 will penetrate the inner hole of the nut. Since the inner diameter of the push rod 41 is smaller than the inner hole diameter of the nut, the nut will gradually be sleeved on the push rod 41 as the push rod 41 moves forward. When the nut is sleeved to a certain depth, the first feed fixing seat 44 will be connected with the second feed fixing seat 44. The push rod 51 will move forward against the front end face of the nut. The depth of the nut inserted into the push rod 41 is the same as the length difference between the push rod 41 and the push rod 51, which can be adjusted according to actual conditions. At this time, the push rod 51 will move forward against the nut. When the nut is displaced, the edge of the nut will gradually squeeze the dislocation block 36. Due to the setting of the inclined guide portion 361 of the dislocation block 36, the nut can smoothly move the inclined guide portion 361. 61 squeezes the dislocation block 36 to retract into the mounting hole 39. After the nut is completely moved, the outer edge of the push rod 51 will continue to squeeze the dislocation block 36 so that it cannot extend out of the conveying channel 31. Finally, the second feeding fixed seat 53 will abut against the dislocation seat 34 to drive the dislocation seat 34 to move forward, and the nut can be directly sent to the next process for reset. After resetting, the dislocation block 36 will pop up again under the action of the dislocation spring 37, and the next fallen nut will be clamped in place, and then the next feeding action will be performed, and the operation will be repeated.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
