Description

Technical Field

[0001] This utility model belongs to the technical field of feeding mechanisms, and in particular relates to a traction-type automatic lathe feeding mechanism. Background Technology

[0002] An automatic feeder is a feeding mechanism that operates automatically according to specified requirements and predetermined procedures. Humans only need to define the control requirements and procedures; direct operation is unnecessary. In other words, it moves items from one location to another automatically and accurately without human intervention. It typically includes detection devices and feeding devices. It is mainly used for conveying various materials and semi-finished industrial products, and can also automate production processes in conjunction with subsequent steps.

[0003] A traction-type rear feeding device for an automatic lathe, disclosed in the public notice (publication number: CN 211805062U), includes a linear feeding plate. The front end of the feeding plate is fixedly connected to the automatic lathe, and the rear end is supported by a support mechanism. A pusher seat is provided on the feeding plate, which slides along the feeding plate via a limiting structure. From front to back, the front end of the feeding plate is provided with a guide seat and a traction feeding mechanism. The guide seat has a through hole for sliding with the bar stock, and the traction feeding mechanism can pull the bar stock into the spindle of the automatic lathe. This invention solves the problem of high structural complexity and high equipment cost in existing automatic lathe rear feeding devices.

[0004] However, the feeding plate, support mechanism, sliding and other components in the above application cannot achieve automatic feeding and discharging. Therefore, we propose a traction-type automatic lathe feeding mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a traction-type automatic lathe feeding mechanism, which solves the existing problems through the design of the feeding device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a traction-type automatic lathe feeding mechanism, including a base, a lathe body fixedly connected to the top of the base, a pusher platform fixedly connected to the side of the base, and a feeding device provided on the top of the pusher platform.

[0008] Furthermore, the feeding device includes a fixed plate fixedly connected to the top of the pusher table. A three-phase asynchronous motor is fixedly connected to the side of the fixed plate, and a threaded rod is fixedly connected to the output shaft of the three-phase asynchronous motor. A limit rod is fixedly connected to the side of the fixed plate, and a threaded sleeve is threaded onto the circumferential surface of the threaded rod. A push rod is fixedly connected to the side of the threaded sleeve, and a push plate is fixedly connected to one end of the push rod. This design enables the feeding device to automatically feed materials onto the lathe, improving work efficiency and saving labor costs.

[0009] Furthermore, the threaded sleeve is slidably connected to the limiting rod, and a rotating shaft is rotatably connected to the side of the push plate. This design allows the threaded sleeve to reciprocate horizontally through the limiting action of the limiting rod.

[0010] Furthermore, a return torsion spring is fixedly connected to the circumference of the rotating shaft, and a folding plate is fixedly connected to one end of the return torsion spring. This design uses the return tension of the return torsion spring to rotate and reset the folding plate.

[0011] Furthermore, a discharge device is provided on the top of the pushing platform. The discharge device includes a material box with a feeding port on its top. A rotating shaft is rotatably connected to the top of the feeding port. A second return torsion spring is fixedly connected to the circumferential surface of the rotating shaft. A cover plate is rotatably connected to the side of the rotating shaft. A discharge port is provided on the side of the material box. A second rotating shaft is fixedly connected to the top of the discharge port. A third return torsion spring is fixedly connected to the circumferential surface of the second rotating shaft. A second cover plate is rotatably connected to the side of the second rotating shaft. This design enables the discharge device to automatically discharge materials, forming an automated system in conjunction with the feeding device.

[0012] Furthermore, one end of the third reset torsion spring is fixedly connected to the side of the second cover plate, and the initial state of the third reset torsion spring is a relaxed state. This design uses the second cover plate to control the discharge and stopping of material discharge.

[0013] Furthermore, the second reset torsion spring is initially in a relaxed state, and a push rod is fixedly connected to the top of the push plate. This design uses the push rod to strike the force-bearing column to open the second cover plate and achieve the effect of material discharge.

[0014] Furthermore, a force-bearing column is fixedly connected to the side of the second cover plate, and the side of the force-bearing column is located on the displacement trajectory of the top rod. This design uses the force on the force-bearing column to drive the second cover plate to achieve the effect of material discharge.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model achieves automatic feeding by using a three-phase asynchronous motor, a threaded rod, a threaded sleeve, a limiting rod, and other components in cooperation. The output shaft of the three-phase asynchronous motor rotates, driving the threaded rod to rotate. The rotation of the threaded rod drives the threaded sleeve to reciprocate horizontally under the restriction of the limiting rod. The reciprocating horizontal movement of the threaded sleeve drives the push rod to reciprocate horizontally, which in turn drives the push plate to reciprocate horizontally. The reciprocating horizontal movement of the push rod drives the folding plate to reciprocate horizontally, thereby achieving automatic feeding, improving work efficiency, and forming automation.

[0017] 2. This utility model utilizes a three-phase asynchronous motor, a threaded rod, a threaded sleeve, a limiting rod, and a material box, among other components, to work together to allow material to be fed into the material box from the inlet. The rotation of the output shaft of the three-phase asynchronous motor drives the threaded rod to rotate. The rotation of the threaded rod causes the threaded sleeve to reciprocate horizontally under the constraint of the limiting rod. The reciprocating horizontal movement of the threaded sleeve drives the push rod to reciprocate horizontally. The reciprocating horizontal movement of the push rod drives the push plate to reciprocate horizontally. The reciprocating horizontal movement of the push plate drives the top rod to reciprocate horizontally. The reciprocating horizontal movement of the top rod impacts the force-bearing column, causing the force-bearing column to rotate clockwise. Thus, the material is discharged through the outlet, achieving an automatic discharge effect and realizing automation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a traction-type automatic lathe feeding mechanism, including a base 1, a lathe body 2 fixedly connected to the top of the base 1, a pusher 3 fixedly connected to the side of the base 1, and a feeding device 4 provided on the top of the pusher 3.

[0029] The feeding device 4 includes a fixed plate 41, which is fixedly connected to the top of the push table 3. A three-phase asynchronous motor 42 is fixedly connected to the side of the fixed plate 41. A threaded rod 43 is fixedly connected to the output shaft of the three-phase asynchronous motor 42. A limit rod 44 is fixedly connected to the side of the fixed plate 41. A threaded sleeve 45 is threadedly connected to the circumference of the threaded rod 43. A push rod 46 is fixedly connected to the side of the threaded sleeve 45. A push plate 47 is fixedly connected to one end of the push rod 46. This design enables the feeding device 4 to automatically feed materials to the lathe, improving work efficiency and saving labor costs.

[0030] The threaded sleeve 45 is slidably connected to the limiting rod 44, and the side of the push plate 47 is rotatably connected to the rotating shaft 48. This design allows the threaded sleeve 45 to reciprocate horizontally through the limiting action of the limiting rod 44.

[0031] A reset torsion spring 49 is fixedly connected to the circumferential surface of the rotating shaft 48, and a folding plate 410 is fixedly connected to one end of the reset torsion spring 49. This design allows the folding plate 410 to rotate and reset by the reset tension of the reset torsion spring 49.

[0032] The top of the push platform 3 is equipped with a discharge device 5, which includes a material box 51. The top of the material box 51 has a feed inlet 52, and a rotating shaft 53 is rotatably connected to the top of the feed inlet 52. A second return torsion spring 54 is fixedly connected to the circumferential surface of the rotating shaft 53. A cover plate 55 is rotatably connected to the side of the rotating shaft 53. The side of the material box 51 has a discharge outlet 56, and the top of the discharge outlet 56 is fixedly connected to a second rotating shaft 57. A third return torsion spring 58 is fixedly connected to the circumferential surface of the second rotating shaft 57, and a second cover plate 59 is rotatably connected to the side of the second rotating shaft 57. This design enables the discharge device 5 to automatically discharge materials, forming an automated system in conjunction with the feeding device 4.

[0033] One end of the third reset torsion spring 58 is fixedly connected to the side of the second cover plate 59, and the initial state of the third reset torsion spring 58 is a relaxed state. This design uses the second cover plate 59 to control the discharge and stop of discharge.

[0034] The second reset torsion spring 54 is initially in a relaxed state, and a push rod 510 is fixedly connected to the top of the push plate 47. This design uses the push rod 510 to strike the force-bearing column 511 to open the second cover plate 59 and achieve the effect of material discharge.

[0035] A force-bearing column 511 is fixedly connected to the side of the second cover plate 59, and the side of the force-bearing column 511 is located on the displacement trajectory of the top rod 510. This design uses the force-bearing column 511 to drive the second cover plate 59 to achieve the effect of material discharge.

[0036] A specific application of this embodiment is as follows: Starting the three-phase asynchronous motor 42 causes the output shaft of the motor to rotate, driving the threaded rod 43 to rotate. The rotation of the threaded rod 43 causes the threaded sleeve 45 to reciprocate horizontally under the constraint of the limiting rod 44. This reciprocating horizontal movement of the threaded sleeve 45 drives the push rod 46 to reciprocate horizontally, which in turn drives the push plate 47 to reciprocate horizontally. This reciprocating horizontal movement of the push rod 46 drives the folding plate 410 to reciprocate horizontally. When the folding plate 410 encounters the material box 51, it encounters resistance and folds. When the resistance is removed, the tension of the return torsion spring 49, through the rotating shaft 48, resets the folding plate 410, causing it to fit against the push plate 47, thus achieving automatic material feeding. This improves work efficiency and reduces labor costs.

[0037] A specific application of this embodiment is as follows: The cover plate 55 is opened, and material is poured into the material box 51 from the feed inlet 52. The cover plate 55 is then reset and closed by the reset pulling force of the second reset torsion spring 54. At this time, the three-phase asynchronous motor 42 is started. The output shaft of the three-phase asynchronous motor 42 rotates, driving the threaded rod 43 to rotate. The rotation of the threaded rod 43 drives the threaded sleeve 45 to reciprocate horizontally under the restriction of the limit rod 44. The reciprocating horizontal movement of the threaded sleeve 45 drives the push rod 46 to reciprocate horizontally. The reciprocating horizontal movement of the push rod 46 drives the push plate 47 to reciprocate horizontally. The horizontal motion of the push plate 47 drives the push rod 510 to reciprocate horizontally. The push rod 510 reciprocates horizontally and impacts the force column 511. The force column 511 is impacted, which causes the second cover plate 59 to rotate clockwise through the second rotating shaft 57. At this time, the material is discharged from the discharge port 56. When the force column 511 loses its impact force, the second cover plate 59 is driven by the reciprocating tension of the third reset torsion spring 58 to rotate counterclockwise through the rotating shaft 53 to reset and close, thereby achieving the effect of automatic material discharge and forming automated material discharge.
