Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a pin-stopping mechanism and its pin conveying device. Background Technology

[0002] During the feeding process, the upper and lower pins in the guide trough need to be locked separately. Two locking mechanisms operate independently, allowing the pins to be fed one by one. For example, a pin screening device, as described in patent application number 202322429897.7, includes a mounting frame. A fixed frame is fixedly mounted on the top of the mounting frame. A detection hole is provided on the side wall of the fixed frame. A guiding mechanism is fixedly mounted on the top of the fixed frame. A detection component is fixedly mounted on the side wall of the fixed frame. A cutting mechanism is fixedly mounted on the top of the mounting frame. A blocking mechanism is fixedly mounted on the bottom of the mounting frame. A discharge pipe penetrating the surface of the mounting frame is fixedly connected to the bottom of the mounting frame. The length of the pins is detected by the detection component. Pins that meet the length requirements are moved into the discharge pipe by the cutting mechanism and proceed to the next processing step. Pins that do not meet the length requirements are collected in a waste collection box through the cooperation of the cutting mechanism and the blocking mechanism. Although this design also includes two telescopic components 14 to lock different pins at the top and bottom, it uses a large-diameter push rod to directly lock the pins. This push rod is prone to damage over time due to wear and requires regular inspection and replacement. Furthermore, the push rod in this design is difficult to disassemble and has high maintenance costs.

[0003] Therefore, the technical problem that this application needs to solve is: how to improve the maintenance efficiency of the push rod. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a pin-stopping mechanism. This solution does not use a guide rod to directly press the pin, but the guide rod only serves as a guide. A blocking component is set on the guide rod to clamp the pin, which can reduce costs. The blocking component uses less material and is cheaper. Moreover, the blocking component can be detached and installed, making it easier to replace and maintain.

[0005] Specifically, this utility model proposes a pin-stopping mechanism, comprising: a guide seat, wherein a first discharge hole is provided vertically through the guide seat, and a clamping channel communicating with the first discharge hole is provided on the guide seat, the width of the clamping channel being smaller than the diameter of the pin; a telescopic member, wherein a guide rod is installed on the output shaft of the telescopic member, the length direction of the guide rod being parallel to the length direction of the clamping channel; and a blocking component, wherein the blocking component is slidably installed in the clamping channel, and an extension arm is provided at one end of the blocking component near the telescopic member, the extension arm being detachably installed on the guide rod.

[0006] Preferably, the blocking component is a strip plate, which is slidably disposed in the abutment channel, and the extension arm is disposed at one end of the strip plate near the telescopic member.

[0007] Preferably, the guide rod is provided with a plug groove, and the extension arm is plugged into the plug groove.

[0008] Preferably, a baffle is fixed to the end of the guide rod away from the telescopic member, and a return spring is provided between the baffle and the guide seat, and the return spring is located on the side of the guide seat away from the telescopic member.

[0009] Preferably, there are two blocking components, which are arranged vertically; there are also two telescopic components used to control the operation of different blocking components.

[0010] In addition, this application also proposes a pin conveying device, including the aforementioned pin blocking mechanism.

[0011] Furthermore, it also includes a support frame for mounting the pin stop mechanism.

[0012] Furthermore, it also includes a cutting assembly, which comprises:

[0013] A push cylinder, which is mounted on the side plate of the support frame;

[0014] A movable plate is mounted on a side plate via a slide rail assembly, and the movable plate is connected to the output shaft of the push cylinder via a drive connection.

[0015] A clamping cylinder is mounted on the movable plate;

[0016] A pusher seat, wherein a second discharge hole is provided through the pusher seat in the vertical direction, the second discharge hole being used to receive pins falling from the first discharge hole;

[0017] The support frame has a baffle plate located at the bottom of the pusher seat to prevent the pin from moving downwards.

[0018] Preferably, the pusher seat is provided with a detection channel in the horizontal direction that communicates with the second discharge through hole, and the detection channel is used so that the light from the photoelectric sensor can illuminate the pin in the second discharge through hole.

[0019] Preferably, the number of pin-stopping mechanisms installed on the support frame is two, and the number of cutting components is two. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0029] like Figures 1 to 4 As shown, this embodiment proposes a pin-stopping mechanism, including: a guide seat 11, which has a first discharge hole 12 extending vertically through it, and a clamping channel 13 communicating with the first discharge hole 12 on the guide seat 11, the width of the clamping channel 13 being smaller than the diameter of the pin; a telescopic member 14, on the output shaft of the telescopic member 14, a guide rod 15 is mounted, the length direction of the guide rod 15 being parallel to the length direction of the clamping channel 13; and a blocking component 16, which is slidably installed in the clamping channel 13, and an extension arm 17 is provided at one end of the blocking component 16 near the telescopic member 14, the extension arm 17 being detachably installed on the guide rod 15.

[0030] The principle of the pin-stopping mechanism is existing technology, and this application will not elaborate on how it works. This application only explains which technical aspects have been improved.

[0031] This application does not use the guide rod 15 to directly press the pin. Instead, the guide rod 15 serves only as a guide, and a blocking component 16 is provided on the guide rod 15 to press the pin. The purpose of doing so is to reduce costs, as the blocking component 16 requires less material and is cheaper. Furthermore, the blocking component 16 is detachable and easier to replace and maintain.

[0032] Furthermore, the guide seat 11 is provided with a guide hole for slidingly mounting the guide rod 15.

[0033] In one embodiment of this invention, the blocking component 16 is a strip plate 18, which is slidably disposed in the abutment channel 13, and the extension arm 17 is disposed at one end of the strip plate 18 near the telescopic member 14.

[0034] Furthermore, the telescopic component 14 is made of electric cylinder, hydraulic cylinder or pneumatic cylinder.

[0035] In one embodiment of this invention, the guide rod 15 is provided with a plug-in groove 19, and the extension arm 17 is plugged into the plug-in groove 19.

[0036] This application adopts a plug-in installation method, which enables faster disassembly of the blocking component 16.

[0037] The travel of the output shaft of the telescopic component 14 is greater than the length of the blocking component 16, which facilitates the complete withdrawal of the blocking component 16 from the clamping channel 13.

[0038] When the telescopic component 14 needs to be tightened against the pin, the reciprocating stroke of the telescopic component 14 is very small, and it is only necessary to loosen the pin.

[0039] As one embodiment of this example, a baffle 20 is fixed to one end of the guide rod 15 away from the telescopic member 14, and a return spring 21 is provided between the baffle 20 and the guide seat 11, and the return spring 21 is located on the side of the guide seat 11 away from the telescopic member 14.

[0040] The return spring 21 is used to move the guide rod 15 toward the telescopic member 14. Its advantage is that the output shaft of the telescopic member 14 does not need to be fixed to the guide rod 15, and there may even be no connection between the telescopic member 14 and the guide rod 15. The driving force of the guide rod 15 can be achieved by the interaction force between the two.

[0041] In one embodiment of this invention, there are two blocking components 16 arranged vertically; there are also two telescopic components 14 used to control the operation of different blocking components 16. The working principle is the same as in the prior art: when the upper pin is locked, the lower pin drops, thus controlling that only one pin drops at a time.

[0042] In addition, this application also proposes a pin conveying device, including the aforementioned pin blocking mechanism.

[0043] Furthermore, it also includes a support frame 23, which is used to install the pin stop mechanism.

[0044] Furthermore, it also includes a cutting assembly 24, which includes:

[0045] Push cylinder 25, which is mounted on the side plate of the support frame 23;

[0046] The movable plate 26 is mounted on the side plate via a slide rail assembly, and the movable plate 26 is connected to the output shaft of the push cylinder 25 via a drive connection.

[0047] Clamping cylinder 27, which is mounted on the movable plate 26;

[0048] The pusher seat 28 is provided with a second material discharge through hole 22 in a vertical direction. The second material discharge through hole 22 is used to receive the pins falling from the first material discharge through hole 12.

[0049] The support frame 23 has a baffle plate 29, which is located at the bottom of the pusher seat 28 and is used to prevent the pin from moving downward.

[0050] The structure and working principle of the cutting component 24 are already conventional technologies, and this application will not go into detail about the working principle of the cutting component.

[0051] As one embodiment of this example, the pusher seat 28 is provided with a detection channel 30 that communicates with the second material discharge through hole 22 in the horizontal direction. The detection channel 30 is used so that the light from the photoelectric sensor 31 can illuminate the pin in the second material discharge through hole 22.

[0052] This solution improves the pusher seat 28, which can detect whether there is a pin in the second discharge through hole 22 through the photoelectric sensor 31.

[0053] In one embodiment of this invention, the number of pin-stopping mechanisms installed on the support frame 23 is two, and the number of cutting components 24 is two.

[0054] For ease of understanding, the relevant existing technologies are described below:

[0055] like Figure 5 As shown, a support plate 32 is provided on the side of the baffle plate 29 away from the push cylinder 25. The support plate 32 is installed on the ground or on the support frame 23 by means of a fixing rod, fixing frame or other fixing structure, or the support plate 32 is welded to the baffle plate 29. The support plate 32 is provided with a discharge channel 33 for conveying the cut pins.

[0056] Alternatively, this application may omit the support plate 32 and the discharge channel 33, and directly feed the pin into the processing position through the cutting assembly 24. A connecting plate is provided between the processing position and the support plate 32, and the upper surface of the connecting plate is flush with the upper surface of the support plate 32 to facilitate the movement of the pusher seat 28.

[0057] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
