DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0030] The present application provides a pin assembly position adjustment device for adjusting the position of the pin assembly 5 installed on the transfer frame 6 through the aluminum row 62. The pin assembly 5 is arranged in multiple rows along the length direction of the transfer frame 6, and there is an adjustment gap between two adjacent rows of opposite pin assemblies 5, such as Figure 6 .

[0031] The device Figure 1As shown, it includes: a support plate 1 and a movable plate 2. The support plate 1 is mounted above the base 3, and the middle part of the support plate 1 is hollow to form a hollow area. The top of the support plate 1 is used to place the transfer rack 6; the movable plate 2 is located between the support plate 1 and the base 3, and is movably arranged on the base 3, and the moving direction of the movable plate 2 is consistent with the length direction of the transfer rack 6 placed on the support plate 1. A plurality of rows of push plates 21 are vertically arranged on the upper surface of the movable plate 2 along the moving direction of the movable plate 2, and the push plates 21 are located in the hollow area; when the transfer rack 6 is placed on the top of the support plate 1, each row of push plates 21 is respectively located in different adjustment gaps.

[0032] When the transfer rack 6 is placed on top of the support plate 1, the push plates 21 arranged on the upper surface of the movable plate 2 are located in the hollow area, and each row of push plates 21 are respectively located in different adjustment gaps. Then, the movable plate 2 reciprocates along the length direction of the transfer rack 6 on the base 3, driving the push plates 21 to press against the pin assemblies 5 arranged on both sides thereof, thereby adjusting the position of the pin assemblies 5 on the transfer rack 6, so that the inner ends of the pin assemblies are correctly located in the aluminum row and the outer ends are neatly arranged.

[0033] Preferably, when placing the transfer rack 6, in order to fix its position on the top of the support plate 1 and the pusher plates 21 are respectively located in different adjustment gaps, such as Figure 1 and Figure 6 As shown, a group of positioning pins 11 are installed on the upper surface of the support plate 1 and are arranged diagonally; a pair of positioning holes 61 are provided on the transfer frame 6, and the positioning holes 61 cooperate with the positioning pins 11 on the support plate to fix the position of the transfer frame 6 and make the push plate 21 located in different adjustment gaps respectively.

[0034] Preferably, based on practical applications, when placing the transfer rack 6, the push plate 21 should be located directly below the hollow area to avoid motion interference between the push plate 21 and the pin assembly 5 when placing the transfer rack 6. Figure 5 and Figure 3 As shown, the movable plate 2 is provided with a plurality of guide posts 42 which are slidably penetrated, and the bottom ends of the guide posts 42 are connected to support blocks 41, and the guide posts 42 are provided with support springs 43 which are connected between the support blocks 41 and the movable plate 2, and the support blocks 41 are in contact with the movable plate 2; the base 3 is provided with a plurality of columns 33, and the movable plate 2 is slidably penetrated by the columns 33. Figure 4As shown, after the transfer frame 6 is installed on the support plate 1, the positioning pin 11 cooperates with the positioning hole 61 on the transfer frame 6 to fix the position of the transfer frame 6 on the support plate 1. Under the action of the guide column 42 and the column 33, the support plate 1 and the transfer frame 6 descend along the guide column 42 due to their own gravity. At this time, the push plate 21 on the moving plate 2 passes through the hollow area of ​​the support plate 1, and the support spring 43 supports the support plate 1 and the transfer frame 6, and makes the support plate 1 stop at the position where the push plate 21 is just located in the adjustment gap. After adjusting the position of the pin assembly 5, remove the transfer frame 6, and restore the position of the support plate 1 under the action of the support spring 43.

[0035] Preferably, when the push plate 21 pushes against the outer end of the pin assembly 5, if the force is too great, the pin assembly will be damaged. Figure 2 As shown, each push plate 21 is provided with a fixed plate 22 on both sides perpendicular to the moving plate 2, and its bottom is connected to the moving plate 2; a push spring 23 is arranged between the push plate 21 and the fixed plate 22, and one end of the push spring 23 is connected to the push plate 21, and the other end is connected to the fixed plate 22. When the push plate 21 pushes against the rear end of the pin assembly 5, if the pushing force is too large, the pin assembly will be impacted. At this time, the impact force is transmitted to the push spring 23 along the push plate 21 and is mitigated by it, so as to avoid damage to the pin assembly 5 due to excessive pushing force.

[0036] Preferably, in order to limit the maximum height of the support plate 1 moving upward along the guide column 42, as Figure 1 As shown, a stopper 34 is fixedly provided on the top of the column 33 . After the transfer rack 6 is removed, the support plate 1 moves upward along the guide column 42 under the action of the support spring 43 , and its maximum height does not exceed the lower surface of the stopper 34 .

[0037] Preferably, in order to achieve the purpose of moving the movable plate 2 along the length direction of the transfer frame 6, the present embodiment adopts a guide groove, a guide block and the like. Figure 1 and Figure 7 As shown, the upper surface of the movable plate 2 is provided with a plurality of guide grooves 24, and the length direction of the guide grooves 24 is consistent with the moving direction of the movable plate 2; the lower surface of the support block 41 is provided with a guide block 44; the guide block 44 cooperates with the guide groove 24; the upper surface of the base 3 is provided with a guide rail 31 along the moving direction of the movable plate 2, and the lower surface of the movable plate 2 is provided with a matching groove 25 along the moving direction of the movable plate 2, and the matching groove 25 is used to cooperate with the guide rail 31. Due to the matching of the matching groove 25 and the guide rail 31, the movable plate 2 can move along the length direction of the transfer frame 6; under the action of the guide groove 24 and the guide block 44, the movable plate 2 can move along the length direction of the transfer frame 6 when the guide column 42 is provided.

[0038] Preferably, in order to achieve the purpose of reciprocating movement of the movable plate 2 in the length direction of the transfer frame 6, as Figure 1As shown, a pushing component 32 is installed on the upper surface of the base 3 and is located on one side of the moving plate 2 , and a movable end of the pushing component 32 is connected to the moving plate 2 .

[0039] Specifically, the pushing assembly can be pneumatic or hydraulic, or other linear mechanisms to perform reciprocating motion along a straight line. In this embodiment, the pushing assembly 32 includes a linear cylinder, whose movable end faces the moving direction of the moving plate 2 and is connected to the moving plate 2. When the linear cylinder is running, its movable end pushes the moving plate 2 to reciprocate, so that the push plate 21 respectively presses against the pin assemblies 5 arranged on both sides of the push plate 21, and adjusts the position of the pin assembly 5 on the transfer frame 6.

[0040] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
