[0002] A pin is a product that can position and fasten components. It has two types: cylindrical and conical. When installing a pin on a component, the press-fitting method or the method of knocking it in with soft metal is usually used. Pins can be divided into split pins, taper pins, straight pins, and grooved pins.

[0003] Nowadays, when pressing a pin into a component, it is first necessary to use a pressing and positioning mechanism to fix the component to prevent deviation during pin pressing. Most positioning mechanisms are fixed on the workbench of the pin press, which easily leads to the inability to replace the positioning mechanism when pressing pins for different components, making the model of the positioning mechanism not match the component, greatly affecting the later work efficiency and having a poor use effect. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when pressing a pin into a component nowadays, it is first necessary to use a pressing and positioning mechanism to fix the component to prevent deviation during pin pressing. Most positioning mechanisms are fixed on the workbench of the pin press, which easily leads to the inability to replace the positioning mechanism when pressing pins for different components, making the model of the positioning mechanism not match the component, greatly affecting the later work efficiency and having a poor use effect, and to propose a pin pressing and positioning mechanism.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A pin pressing and positioning mechanism, including an installation base, a positioning base, and a positioning module. A positioning module is arranged on the top surface of the positioning base. A chute is arranged on the top surface of the installation base. A slider is fixedly installed at the top of the positioning base. Quick-release components are arranged at the bottoms on both sides of the positioning base. A cleaning component is arranged on the inner wall of the chute.

[0006] As a further description of the above technical scheme:

[0007] The quick-release component includes an arcuate plate fixedly installed at the bottoms on both sides of the positioning base. A fixing plate is slidably installed on the inner wall of the arcuate plate. A limit pin is fixedly installed on one side of the fixing plate.

[0008] As a further description of the above technical scheme:

[0009] On the other side of the fixed plate, a support rod is fixedly installed. The support rod passes through a through hole provided on the outer wall of the bow-shaped plate, and a circular plate is fixedly installed at the other end of the support rod.

[0010] As a further description of the above technical solution:

[0011] A pull rod is fixedly installed on the outer wall of the circular plate. A first spring is sleeved on the outer wall of the support rod. One end of the first spring is fixedly installed on the outer wall of the fixed plate, and the other end of the first spring is fixedly installed on the inner wall of the bow-shaped plate.

[0012] As a further description of the above technical solution:

[0013] The cleaning assembly includes a cleaning plate. The cleaning plate is slidably installed on the inner wall of the chute. A cleaning brush is fixedly installed at the bottom of the cleaning plate, and a telescopic rod is fixedly installed on the outer wall of the cleaning plate.

[0014] As a further description of the above technical solution:

[0015] The other end of the telescopic rod is fixedly installed with a baffle. A bottom block is fixedly installed at the bottom of the baffle, and a second spring is sleeved on the outer wall of the telescopic rod.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, by providing a quick-release assembly, when replacing different models of positioning modules on the installation base, only need to pull the pull rod. The pull rod drives the circular plate to displace, the circular plate drives the support rod to displace, and the support rod also drives the fixed plate to displace at the same time, so that the fixed plate squeezes the first spring to form a compressed state. The fixed plate also drives the limit pin to displace at the same time, and the limit pin moves out from the limit holes provided on both sides of the installation base, and then moves the slider out of the chute, so that the slider drives the positioning base to displace, and replaces the old positioning mechanism with a new one. Through this design, the replacement of different models of positioning mechanisms is effectively realized, avoiding the mismatch between the model of the positioning mechanism and the parts, and preventing the difference between the model of the positioning mechanism and the parts from affecting the later work efficiency, and the use effect is good.

[0018] 2. In the present utility model, by providing a cleaning component, when installing a positioning mechanism of a new model, the slider provided at the bottom of the positioning base is aligned with the chute. When the slider is installed inside the chute, during this process, the slider pushes the cleaning plate. While the cleaning plate is displaced, it drives the cleaning brush to be displaced on the inner wall of the chute, and at the same time, the cleaning plate presses the second spring to form a compressed state. Since the length of the slider is slightly shorter than that of the chute, the cleaning plate stops at one end inside the chute. Through this design, it effectively realizes the cleaning of the chute that is difficult to clean, eliminating the need for staff to clean it, greatly reducing the labor intensity of manual work, and having good use effects.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0026] Please refer to Figures 1-4, the utility model provides a technical solution: a pin pressing and positioning mechanism, which includes an installation base 1, a positioning base 2 and a positioning module 3. A positioning module 3 is arranged on the top surface of the positioning base 2. A chute 7 is arranged on the top surface of the installation base 1. A slider 6 is fixedly installed at the top of the positioning base 2. Quick-release components 4 are arranged at the bottoms on both sides of the positioning base 2. A cleaning component 5 is arranged on the inner wall of the chute 7;

[0027] The quick-release component 4 includes an arcuate plate 41, which is fixedly installed at the bottoms on both sides of the positioning base 2. A fixing plate 42 is slidably installed on the inner wall of the arcuate plate 41. A limit pin 43 is fixedly installed on one side of the fixing plate 42. A support rod 44 is fixedly installed on the other side of the fixing plate 42. The support rod 44 passes through a through hole arranged on the outer wall of the arcuate plate 41. The other end of the support rod 44 is fixedly installed with a circular plate 46. A pull rod 47 is fixedly installed on the outer wall of the circular plate 46. A first spring 45 is sleeved on the outer wall of the support rod 44. One end of the first spring 45 is fixedly installed on the outer wall of the fixing plate 42, and the other end of the first spring 45 is fixedly installed on the inner wall of the arcuate plate 41;

[0028] The specific implementation method is: when replacing the positioning module 3 of different models on the installation base 1, only need to pull the pull rod 47. The pull rod 47 drives the circular plate 46 to displace. The circular plate 46 drives the support rod 44 to displace. The support rod 44 also drives the fixing plate 42 to displace at the same time, so that the fixing plate 42 squeezes the first spring 45 to form a compressed state. The fixing plate 42 also drives the limit pin 43 to displace at the same time. The limit pin 43 moves out from the limit holes arranged on both sides of the installation base 1, and then moves out of the slider 6 from the chute 7, so that the slider 6 drives the positioning base 2 to displace, and replaces the old positioning mechanism with a new one.

[0029] The cleaning component 5 includes a cleaning plate 51, which is slidably installed on the inner wall of the chute 7. A cleaning brush 52 is fixedly installed at the bottom of the cleaning plate 51. A telescopic rod 53 is fixedly installed on the outer wall of the cleaning plate 51. The other end of the telescopic rod 53 is fixedly installed with a baffle 55. A bottom block 56 is fixedly installed at the bottom of the baffle 55. A second spring 54 is sleeved on the outer wall of the telescopic rod 53;

[0030] The specific implementation method is: when installing a new type of positioning mechanism, the slider 6 arranged at the bottom of the positioning base is aligned with the chute 7. When the slider 6 is installed into the chute 7, during this process, the slider 6 pushes the cleaning plate 51. When the cleaning plate 51 displaces, it drives the cleaning brush 52 to displace on the inner wall of the chute 7. The cleaning plate 51 also squeezes the second spring 54 to form a compressed state. Because the length of the slider 6 is slightly shorter than that of the chute 7, the cleaning plate 51 displaces to the end inside the chute 7 and stops.

[0031] Working principle: When replacing the positioning module 3 of different models on the installation base 1, only need to pull the pull rod 47. The pull rod 47 drives the circular plate 46 to displace, the circular plate 46 drives the support rod 44 to displace, and the support rod 44 also drives the fixed plate 42 to displace at the same time, so that the fixed plate 42 squeezes the first spring 45 to form a compressed state of the first spring 45. The fixed plate 42 also drives the limit pin 43 to displace at the same time. The limit pin 43 moves out of the limit holes arranged on both sides of the installation base 1, and then moves the slider 6 out of the chute 7, so that the slider 6 drives the positioning base 2 to displace, replacing the old positioning mechanism with a new one. When installing a new type of positioning mechanism, the slider 6 arranged at the bottom of the positioning base is aligned with the chute 7. When the slider 6 is installed inside the chute 7, during this process, the slider 6 pushes the cleaning plate 51, and the cleaning plate 51 drives the cleaning brush 52 to displace on the inner wall of the chute 7 while displacing. The cleaning plate 51 also squeezes the second spring 54 to form a compressed state. Because the length of the slider 6 is slightly shorter than that of the chute 7, the cleaning plate 51 stops at one end inside the chute 7 when it displaces.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
