Description

Technical Field

[0001] This utility model belongs to the field of positioning pin feeding technology, specifically relating to a positioning pin feeding mechanism. Background Technology

[0002] As a key positioning component, industrial mechanical locating pins are widely used in automobile manufacturing, aerospace, precision instruments, and other fields. Their core function is to ensure the geometric accuracy and repeatability of equipment assembly through high-precision fitting. In traditional production processes, the loading of locating pins often relies on manual operation or semi-automatic mechanical devices, which results in problems such as low efficiency, fluctuations in positioning accuracy due to human factors, and insufficient stability during high-speed continuous operation.

[0003] Currently, most existing methods for feeding locating pins employ blowing technology, which uses a pneumatic device to blow the locating pins into designated positions. However, this method has the following drawbacks:

[0004] 1. Easy to jam or not blown to the target position: Due to unstable airflow or deviation of the positioning pin posture, the positioning pin is easy to get stuck in the material tube or not reach the target position accurately.

[0005] 2. Severe wear of the material tube: During the blowing process, the positioning pin rubs frequently with the material tube (usually a polyurethane transparent tube), causing the material tube to wear out quickly and requiring frequent replacement, which increases maintenance costs;

[0006] 3. Low reliability: The blowing method relies on the stability of air pressure. Environmental changes (such as temperature and humidity) can easily affect the feeding accuracy, making it difficult to adapt to the needs of high-cycle production.

[0007] To address the aforementioned issues, this application proposes a positioning pin feeding mechanism. Utility Model Content

[0008] To address the aforementioned problems in the existing technology, this utility model provides a positioning pin feeding mechanism, which features stable feeding through physical pushing and posture adjustment, reduces reliance on pneumatic components, and extends the service life of the feed tube.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a positioning pin feeding mechanism, comprising a first frame, on which a vibratory feeder and a linear vibratory conveyor are respectively mounted, the horizontal feeding track on the linear vibratory conveyor being connected to the discharge end of the vibratory feeder, and a second frame located on the side of the linear vibratory conveyor away from the vibratory feeder, a rotary cylinder being fixedly connected to the top of the second frame, and a tilting seat being fixed to the output end of the rotary cylinder, the tilting seat being located on the side of the horizontal feeding track away from the vibratory feeder, the positioning pin fed in by the horizontal feeding track being rotated from a horizontal state to a vertical state by the rotation of the tilting seat driven by the rotary cylinder.

[0010] As a preferred technical solution of this utility model, the flipping seat is provided with interconnected pin holes and push holes along the radial direction. At least part of the positioning pin can be inserted into the pin hole. The push hole is provided with a push rod adapted to it. The top of the push rod is formed with a part that can penetrate the pin hole. After the push rod is inserted into the push hole, the positioning pin is pushed out in a vertical state.

[0011] As a preferred technical solution of this utility model, a slide cylinder is fixed to the side of the second frame by a bracket, and the push rod is fixed to the output end of the slide cylinder, and both are in a vertical state.

[0012] As a preferred technical solution of this utility model, the side of the flip base is provided with a sensing hole perpendicular to the pin hole, and a proximity switch for sensing the positioning pin is installed on the side of the flip base, and the front end of the proximity switch is located in the sensing hole.

[0013] As a preferred technical solution of this utility model, the flipping seat is an overall "D" shaped structure, wherein the arc-shaped part is always in contact with the discharge end of the horizontal feeding track.

[0014] As a preferred embodiment of this utility model, the push rod is chrome-plated and has an arc-shaped top.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model uses mechanical pushing instead of pneumatic blowing to solve the problems of material jamming and incomplete blowing, effectively ensuring the success rate of feeding and improving the reliability of the feeding mechanism;

[0017] This invention eliminates the traditional polyurethane material tube and adopts a rigid push rod, which effectively reduces the wear rate, extends the maintenance cycle, and consequently extends the service life.

[0018] The rotary cylinder, tilting seat, and proximity switch of this invention ensure the orientation of the positioning pin and ensure that it enters the material handling station in a vertical state. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Please see Figures 1-4 The present invention provides the following technical solution: a positioning pin feeding mechanism, including a first frame 1, on which a vibratory feeder 2 and a linear vibratory conveyor 3 are respectively installed. The horizontal feeding track 31 on the linear vibratory conveyor 3 is connected to the discharge end of the vibratory feeder 2. The mechanism also includes a second frame 4 located on the side of the linear vibratory conveyor 3 away from the vibratory feeder 2. A rotary cylinder 5 is fixedly connected to the top of the second frame 4. A flipping seat 6 is fixed to the output end of the rotary cylinder 5. The flipping seat 6 is located at the end of the horizontal feeding track 31 away from the vibratory feeder 2. The positioning pin 10 fed by the horizontal feeding track 31 is rotated from a horizontal state to a vertical state by rotating the flipping seat 6 driven by the rotary cylinder 5.

[0028] Specifically, the flipping seat 6 has interconnected pin holes 61 and push holes 62 along the radial direction. At least a portion of the positioning pin 10 can be inserted into the pin hole 61. The push hole 62 is provided with a push rod 8 that is adapted to it. The top of the push rod 8 has a part that can pass through the pin hole 61. After the push rod 8 is inserted into the push hole 62, the positioning pin 10 is pushed out in a vertical state. The push hole 62 can pre-position the push rod 8 to ensure the accuracy when the positioning pin 10 is pushed out.

[0029] Specifically, a slide cylinder 7 is fixed to the side of the second frame 4 by a bracket. The push rod 8 is fixed to the output end of the slide cylinder 7, and both are in a vertical state. The slide cylinder 7 and the push rod 8 work together to push the vertical positioning pin 10 out of the pin hole 61 and then the external material handling mechanism completes the gripping.

[0030] Specifically, the side of the flip base 6 has a sensing hole 63 perpendicular to the pin hole 61. The side of the flip base 6 is equipped with a proximity switch 9 that senses the positioning pin 10 in place, and the front end of the proximity switch 9 is located in the sensing hole 63. The proximity switch 9 is used to sense whether the positioning pin 10 is in place, and the signal is transmitted to the PCL. The PCL is electrically connected to the rotary cylinder 5 and the slide cylinder 7 to ensure accurate action timing.

[0031] Specifically, the flipping seat 6 has an overall "D" shaped structure, in which the arc part is always in contact with the discharge end of the horizontal feeding track 31. The "D" shape ensures the connection between the flipping seat 6 and the horizontal feeding track 31 when the flipping seat 6 rotates back and forth, and at the same time avoids the phenomenon of material jamming.

[0032] Specifically, the push rod 8 is chrome-plated and has an arc-shaped top. The surface of the push rod 8 is plated with hard chrome, which has better wear resistance. The arc-shaped top makes it easier to insert and reduces frictional resistance.

[0033] The working principle and usage process of this utility model are as follows: The positioning pin is placed in the vibratory feeder 2. The vibratory feeder 2 and the linear vibratory conveyor 3 are started. Under the action of the vibratory feeder 2, the positioning pin is conveyed to the horizontal feeding track 31. Under the action of the linear vibratory conveyor 3, the positioning pin is conveyed towards the tilting seat 6. Under the vibration of the linear vibratory conveyor 3, the positioning pin enters the pin hole 61. At this time, the proximity switch 9 senses that the positioning pin is in place. Then, the rotary cylinder 5 is started to drive the tilting seat 6 and the positioning pin to rotate upward to a vertical state. The slide cylinder 7 moves the push rod 8 upward. When the push rod 8 enters the push hole 62, it is precisely positioned and then pushes the positioning pin upward from the pin hole 61. The external material picking mechanism completes the grabbing. Then, the slide cylinder 7 drives the push rod 8 to reset downward. The rotary cylinder 5 drives the tilting seat 6 to reset in the opposite direction and continues the feeding action.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
