[0002] Elastic pins, also known as elastic cylindrical pins and spring pins, are headless hollow cylindrical bodies with axial slots and chamfered ends. They are used for positioning, connection, and fixation between parts. They need to have good elasticity and shear resistance. The outer diameter of this type of pin is slightly larger than the assembly hole diameter. During the installation of forklifts, it is often necessary to install elastic pins for positioning, connection, or positioning. The elastic pins are connected with the elastic pin holes on the installation shaft. This structure is simple and the elastic pins are not easy to fall off, which is very practical.

DETAILED DESCRIPTION

[0040] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0041] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0042] like Figures 1 to 8 As shown, the present invention provides an assembly device for a pin shaft and an elastic pin, comprising:

[0043] A first discharging mechanism 100 is used as a discharging mechanism for the pin shaft, and a first discharging channel is provided on the first discharging mechanism 100, wherein a hopper 110 for storing the pin shaft is provided at one end of the first discharging channel, and a discharging pipe 120 is provided at the other end of the first discharging channel;

[0044] A second discharging mechanism 200 is a discharging mechanism for an elastic pin, and a second discharging channel is provided on the second discharging mechanism 200, wherein a vibration plate 210 for storing the elastic pin is provided at one end of the second discharging channel, a positioning seat 220 connected to the discharging pipe 120 is provided at the other end of the second discharging channel, and a first pushing channel and a second pushing channel are provided on the positioning seat 220, which are perpendicular to each other and connected to each other;

[0045] The first pushing mechanism 300 and the positioning seat 220 are respectively located at the two ends of the discharge pipe 120. The pin shaft on the discharge pipe 120 is pushed into the positioning seat 220 by the first pushing mechanism 300, so that the elastic pin hole on the pin shaft is aligned with the second pushing channel;

[0046] The second pushing mechanism 400 is disposed on the first pushing channel, and the elastic pin is pushed onto the second pushing channel by the second pushing mechanism 400;

[0047] The third pushing mechanism 500 is disposed on the second pushing channel, and the elastic pin is inserted into the elastic pin hole of the pin shaft in the positioning seat 220 through the third pushing mechanism 500.

[0048] The present invention provides an assembly device for a pin shaft and an elastic pin, which realizes the discharging of the pin shaft and the elastic pin through a first discharging mechanism 100 and a second discharging mechanism 200 respectively, and inserts the elastic pin into the elastic pin hole of the pin shaft through a first pushing mechanism 300, a second pushing mechanism 400 and a third pushing mechanism 500, thereby realizing the automatic assembly of the pin shaft and the elastic pin, improving the assembly efficiency of the two and reducing the labor intensity.

[0049] Preferably, since the pin shaft is arranged in a columnar structure, in order to prevent the pin shaft from not rotating when the elastic pin is inserted into the elastic pin hole, it is necessary to position the pin shaft before the elastic pin is inserted into the elastic pin hole to prevent it from rotating. Therefore, a positioning motor 230 is installed on the positioning seat 220, and a positioning tube 240 is connected to the output end of the positioning motor 230, wherein the positioning tube 240 is inserted into the positioning seat 220 and forms a plug-in fit with the elastic pin hole on the pin shaft in the positioning seat 220.

[0050] Further preferably, when the elastic pin is pushed into the elastic pin hole by the third pushing mechanism 500, if the positioning tube 240 is always in the elastic pin hole, as the third pushing mechanism 500 continues to push the elastic pin into the elastic pin hole, on the one hand, the elastic pin and the positioning tube 240 will collide, causing damage to the elastic pin, the positioning tube 240 and the positioning motor 230, and on the other hand, the elastic pin will not be able to be plugged into place. Therefore, when the elastic pin is partially inserted into the elastic pin hole, a signal needs to be given to the positioning motor 230 to prompt the positioning motor 230 to start and withdraw the positioning tube 240 from the elastic pin hole. Therefore, a proximity switch 250 is installed on the third pushing mechanism 500, wherein the proximity switch 250 is aligned with the output end of the third pushing mechanism 500. When the output end of the third pushing mechanism 500 pushes the elastic pin out a certain distance (this distance can ensure that the elastic pin has been partially inserted into the elastic pin hole), the proximity switch 250 is triggered to drive the positioning motor 230 to work, thereby pulling the positioning tube 240 out of the elastic pin hole to avoid the collision between the positioning tube 240 and the elastic pin, thereby improving the service life of the positioning motor 230 and the positioning tube 240, avoiding the waste of the elastic pin, and ensuring that the elastic pin is plugged in place.

[0051] Further preferably, a blanking chute 260 is provided below the positioning seat 220. When the elastic pin and the pin shaft are assembled, the assembled product is pushed out of the positioning seat 220 and enters the blanking chute 260 under the action of the first pushing mechanism 300 to realize product output.

[0052] Preferably, since the pin is arranged in a columnar structure, and the axial direction of the elastic pin hole on the pin is perpendicular to the axial direction of the pin, and the pin is transported in a rolling manner during the transportation on the first discharge channel, in order to ensure that the elastic pin can be accurately inserted into the elastic pin hole, the axial direction of the elastic pin hole of the pin on the discharge pipe 120 must be aligned with the second push channel. Therefore, a reversing mechanism 600 is arranged at one end of the discharge pipe 120. When the axial direction of the elastic pin hole is not parallel to the second push channel, the reversing mechanism 600 drives the pin to rotate until the axial direction of the elastic pin hole is aligned with the second push channel, thereby ensuring that the elastic pin can be accurately inserted into the elastic pin hole under the push of the third push mechanism 500.

[0053] Further preferably, the reversing mechanism 600 includes: a motor mounting seat 610, which is L-shaped and one end of which is connected to the positioning seat 220; a reversing motor 620, which is mounted on the other end of the motor mounting seat 610, and the output end of the reversing motor 620 is connected to a first synchronous wheel 630; a second synchronous wheel 640, which is mounted on the motor mounting seat 610 and is arranged up and down with the first synchronous wheel 630, wherein the axial direction of the second synchronous wheel 640 is parallel to the axial direction of the first synchronous wheel 630; two bearing seats 650, which are respectively located on both sides of the discharge pipe 120, and each bearing seat 650 is connected to a bearing 660, wherein the first synchronous wheel 6 30. The second synchronous wheel 640 and the two bearings 660 are located in the same vertical plane; the synchronous belt 670 is arranged in a ring shape, one end of the synchronous belt 670 is connected to the first synchronous wheel 630, and the other end of the synchronous belt 670 is synchronously connected to the second synchronous wheel 640 through two bearings 660, forming an "A" type structure, wherein the synchronous belts 670 on both sides of the first synchronous wheel 630 form a clamping fit with the pin shaft on the discharge pipe 120, and the first synchronous wheel 630 is driven to rotate through the reversing motor 620, and the pin shaft is driven to rotate through the cooperation of the synchronous belt 670, the second synchronous wheel 640 and the two bearings 660, thereby changing the axial direction of the elastic pin hole.

[0054] Further preferably, in order to adjust the tension of the synchronous belt 670 and ensure that there is always a constant clamping force between the synchronous belt 670 and the pin shaft, an adjustment mechanism for adjusting the tension of the synchronous belt 670 is required, and the adjustment mechanism can adjust the tension of the synchronous belt 670 by adjusting the relative distance between the first synchronous wheel 630 and the second synchronous wheel 640, or by adjusting the relative distance between the two bearing seats 650 (bearings 660). Therefore, the adjustment mechanism is divided into a first adjustment mechanism 700 and a second adjustment mechanism 800, wherein the first adjustment mechanism 700 is used to adjust the relative distance between the first synchronous wheel 630 and the second synchronous wheel 640, and the second adjustment mechanism 800 is used to adjust the relative distance between the two bearing seats 650 (bearings 660).

[0055] Further preferably, the first adjustment mechanism 700 includes an adjustment hole 710 arranged on the motor mounting base 610, which is arranged in the shape of an oblong hole; a tensioning shaft 720, one end of which is connected to the second synchronization wheel 640, and the other end passes through the adjustment hole 710; a tensioning block 730, which is installed on the motor mounting base 610 and is located at one end of the adjustment hole 710; an adjustment rod 740, which passes through the tensioning block 730 and is connected to the tensioning shaft 720, wherein the adjustment rod 740 is threadedly matched with the tensioning block 730.

[0056] In this embodiment, the adjusting rod 740 is rotated to drive the tensioning shaft 720 to move up and down along the length direction of the adjusting hole 710 , thereby changing the relative distance between the first synchronous wheel 630 and the second synchronous wheel 640 .

[0057] Further preferably, the second adjustment mechanism 800 includes a U-shaped guide rail frame 810, wherein two bearing seats 650 are connected to both sides of the open end of the guide rail frame 810; a tensioning motor 820 is installed on one of the bearing seats 650, wherein the output end of the tensioning motor 820 is connected to the other bearing seat 650; and a guide rod 830, wherein both ends are respectively connected to the two bearing seats 650.

[0058] In this embodiment, the bearing seat 650 connected to the output end of the tensioning motor 820 is a movable bearing seat 650, and the bearing seat 650 installed as the tensioning motor 820 is a fixed bearing seat 650. The movable bearing seat 650 is driven by the tensioning motor 820 to move back and forth along the guide rod 830, thereby changing the relative distance between the two bearing seats 650 (bearings 660).

[0059] Preferably, in order to improve work efficiency and ensure that the pins are output uninterruptedly, a large number of pins are stored in the hopper 110 and are arranged in a superimposed manner. However, the pins and the elastic pins are assembled one-to-one, which requires that the pins need to be output one by one. Therefore, a material distribution mechanism 900 needs to be set at the discharge end of the hopper 110 to achieve the output of the pins one by one. The material distribution mechanism 900 includes a material distribution cylinder 910, which is installed on the hopper 110, and the output end of the material distribution cylinder 910 is connected to a bottom plate 920, wherein a plurality of movable plates 930 arranged at equal distances are connected to the bottom plate 920, and the movable plates 930 extend from bottom to top into the hopper 110; a plurality of fixed plates 940 are located between two adjacent movable plates 930, wherein the two ends of the fixed plates 940 are respectively connected to the two side walls of the hopper 110.

[0060] In this embodiment, when the material distribution cylinder 910 drives the base plate 920 to move up and down, the movable plate 930 connected to the base plate 920 moves up and down synchronously, so that the pins located in the hopper 110 move up one by one in a "climbing stairs" manner, and are finally output from the discharge port of the hopper 110.

[0061] For example, when only a single pin is left in the hopper 110, the material distribution cylinder 910 drives the movable plate 930 to move downward through the bottom plate 920, so that each movable plate 930 is misaligned with the adjacent fixed plate 940. When the lower edge of one of the movable plates 930 is flush with the bottom wall of the hopper 110, the pin in the hopper 110 rolls onto the movable plate 930, and then the material distribution cylinder 910 drives the movable plate 930 to move upward. When the movable plate 930 is flush with the adjacent fixed plate 940, the movement of the movable plate 930 is stopped. At this time, the pin rolls onto the fixed plate 940, and then the material distribution cylinder 910 continues to move downward and upward, thereby realizing the "stair-climbing" advance of the pin until it is output from the discharge port of the hopper 110.

[0062] Further preferably, the bottom wall of the hopper 110 is inclined to further facilitate the output of the pin.

[0063] Further preferably, the first discharging channel is arranged in a Z shape, and the first discharging channel includes a first discharging sub-channel, a second discharging sub-channel and a third discharging sub-channel which are interconnected, wherein a first discharging plate 130 is arranged on the first discharging sub-channel, a second discharging plate 140 is arranged on the third discharging sub-channel, and the first discharging plate 130 and the second discharging plate 140 are arranged in an upward and downward offset manner, a guide trough 150 is arranged between the first discharging plate 130 and the second discharging plate 140, and a conveying structure 160 is arranged on the guide trough 150 to transport the pin shaft in the first discharging plate 130 to the second discharging plate 140 via the guide trough 150.

[0064] In this embodiment, the pins in the hopper 110 are output one by one to the first discharge plate 130 through the material distribution mechanism 900. Since the bottom of the first discharge plate 130 is inclined, the pins entering the first discharge plate 130 roll into the guide groove 150 due to gravity, and then are transported to the second discharge plate 140 through the conveying structure 160. Since the bottom of the second discharge plate 140 is inclined, the pins entering the second discharge plate 140 roll into the discharge pipe 120 due to gravity.

[0065] Further preferably, the conveying structure 160 includes a material guiding seat 161 , and a material guiding motor 162 is installed on the material guiding seat 161 , wherein the output end of the material guiding motor 162 is connected to a conveyor belt 163 , and the conveyor belt 163 is located at the bottom of the material guiding trough 150 .

[0066] Preferably, in order to ensure that the pin in the guide trough 150 can smoothly enter the second discharge plate 140, a pushing structure 170 is provided on the end of the guide trough 150 away from the first discharge plate 130, wherein the pushing structure 170 includes a fourth pushing cylinder 171 installed on the trough wall of the guide trough 150, wherein the output end of the fourth pushing cylinder 171 is connected to a pushing block 172, wherein the pushing block 172 is V-shaped on one side facing the guide trough. The fourth pushing cylinder 171 drives the pushing block 172 to push the pin in the guide trough 150 into the second discharge plate 140.

[0067] Further preferably, in order to be able to automatically trigger the fourth pushing cylinder 171, a proximity switch 250 is provided on one end of the guide trough 150 close to the fourth pushing cylinder 171. When the pin shaft is transported to the feed port of the second discharge plate 140 through the conveyor belt 163, the proximity switch 250 is triggered to start the fourth pushing cylinder 171, thereby pushing the pin shaft into the second discharge plate 140 through the pushing block 172.

[0068] Preferably, in order to allow the pin in the second discharge plate 140 to roll into the discharge pipe 120 accurately during the rolling process without flying out of the discharge pipe 120, two pressing plates 180 are provided on one end of the second discharge plate 140 close to the discharge pipe 120, and the two pressing plates 180 are arranged opposite to each other, wherein the pressing plates 180 are arranged in an L shape, so that the pin can smoothly enter the discharge pipe 120 along the inner side of the L-shaped pressing plate 180.

[0069] Preferably, the first pushing mechanism 300 includes a first pushing cylinder 310 , and the output end of the first pushing cylinder 310 is connected to a clamp 320 , wherein the clamp 320 is connected to a push rod 330 that nests with the discharge pipe 120 .

[0070] Preferably, the second pushing mechanism 400 includes a second pushing cylinder 410 , and an output end of the second pushing cylinder 410 is connected to a pushing plate 420 .

[0071] Preferably, the third pushing mechanism 500 includes a third pushing cylinder 510 , and a punching needle 520 is connected to the output end of the third pushing cylinder 510 .

[0072] The working principle of the assembly equipment of a pin shaft and an elastic pin provided by the present invention is as follows:

[0073] Discharging of the pin shaft: the material distribution cylinder 910 drives the movable plate 930 to move up and down, so that the pin shafts in the hopper 110 enter the first discharge plate 130 one by one, and roll down into the guide trough 150 smoothly. Then the guide motor 162 drives the conveyor belt 163 to rotate, and transports the pin shafts in the guide trough 150 to the feed port of the second discharge plate 140. Then, the fourth pushing cylinder 171 drives the pushing block 172 to push the pin shaft in the guide trough 150 into the second discharge plate 140, and rolls down into the discharge pipe 120 smoothly. Finally, the third pushing cylinder 510 drives the push rod 330 to insert the pin shaft part into the positioning seat 220, so that the elastic pin hole on the pin shaft is aligned with the second pushing channel.
