DETAILED DESCRIPTION

[0024] The following embodiments are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0025] like Figure 1 to Figure 5As shown, the nut closing positioning device of the utility model includes a base 10, a first guide rail portion 31, a second guide rail portion 32 and an elastic pressing member 20. The first guide rail portion 31 and the second guide rail portion 32 are arranged on the base 10 and extend along the first direction X. The first guide rail portion 31 and the second guide rail portion 32 are spaced to form a guide groove 40, which is used for the workpiece to be limited and moved, so as to facilitate the workpiece to be processed to be pushed into the positioning point, and the processed workpiece is pushed out from the positioning point, so as to facilitate the processing of the next workpiece. The elastic pressing member 20 is arranged in the guide groove 40, and the elastic pressing member 20 always has a tendency to drive the workpiece entering the guide groove 40 to be pressed against the guide groove 40 along the second direction Y different from the first direction X, so that the workpiece entering the elastic pressing member 20 and the guide groove 40 is pressed and cannot move, thereby achieving the fixation of the workpiece and facilitating the processing of the workpiece.

[0026] When the workpiece enters the guide groove 40, when the elastic pressing member 20 does not provide any action, the workpiece is relatively movable in the guide groove 40 and is easy to push; when the workpiece enters the action range of the elastic pressing member 20, the elastic pressing member 20 presses the workpiece between the elastic pressing member 20 and the guide groove 40, so that it is in a relatively fixed state due to static friction. At this time, in the second direction Y, the freedom of movement of the workpiece is restricted, and the workpiece is fixed, so that it is convenient to process the workpiece. When the processing is completed, under the action of a certain external force, the workpiece can be pushed out from the current position along the first direction X to facilitate the processing of the next workpiece, thereby realizing continuous processing.

[0027] Furthermore, if Figure 1 As shown, the elastic pressing member 20 is arranged at the bottom of the guide groove 40, and the elastic pressing member 20 always has a tendency to drive the workpiece entering between the guide groove 40 and the elastic pressing member 20 to press against the top of the guide groove 40 along the second direction Y perpendicular to the first direction X. In this way, the freedom of movement of the workpiece in the second direction Y can be better restricted, thereby facilitating the improvement of processing accuracy.

[0028] Furthermore, if Figure 1 As shown, the elastic pressing member 20 includes a pushing plate 21 and a spring 22 .

[0029] The push plate 21 is arranged in the guide groove 40 and has a degree of freedom of movement at least in the second direction Y. The spring 22 is arranged between the push plate 21 and the base 10, and the spring 22 always has a tendency to drive the push plate 21 away from the base 10. When the workpiece enters the action range of the elastic pressing member 20, the workpiece will press the elastic pressing member 20 in the direction opposite to the second direction Y, and the elastic pressing member 20 will apply a pressing force along the second direction Y to the workpiece, so that the degree of freedom of the workpiece in the second direction Y is restricted, thereby achieving the fixation of the workpiece and facilitating the processing of the workpiece.

[0030] In order to facilitate the setting of the push plate 21, Figure 2 , Figure 3 , Figure 4 As shown, a movable hole 11 is provided on the base 10 , the push plate 21 is movably provided in the movable hole 11 , and the spring 22 is provided in the push plate 21 and the movable hole 11 .

[0031] Further, for the convenience of installation, a first hole portion 111 and a second hole portion 112 are provided on the movable hole 11. The first hole portion 111 and the second hole portion 112 are connected to each other, and the axial direction thereof is arranged along the second direction Y. Accordingly, the push plate 21 includes a base portion 212 and a positioning portion 211, which are fixedly connected or integrally formed. The positioning portion 211 is protrudingly provided on the base portion 212, and a step structure is formed between the positioning portion 211 and the base portion 212.

[0032] The positioning portion 211 is movably disposed in the first hole 111 , the base portion 212 is movably disposed in the second hole 112 , and the base portion 212 cannot pass through the first hole 111 .

[0033] The push plate 21 is movably arranged in the movable hole 11 in a substantially shape-matched manner, and the push plate 21 has a certain degree of freedom of movement in the second direction Y. The degree of freedom in directions other than the second direction Y may be restricted or not, and the specific degree of freedom may be set according to needs. Preferably, the degree of freedom of the push plate 21 in directions other than the second direction Y is restricted.

[0034] The shape of the base 212 is not limited. In this embodiment, the base 212 is circular, and the second hole 112 matches the shape of the base 212 and is also circular.

[0035] The positioning portion 211 is extended as a whole along the first direction X, and its specific shape is not limited. In this embodiment, it is in a long strip shape and is arranged on the diameter line of the base 212. Correspondingly, the first hole portion 111 is a strip-shaped hole.

[0036] Furthermore, if Figure 1 As shown, in order to facilitate the installation of the push plate 21 on the base 10 , the base 10 includes a base 12 and a fixing block 13 .

[0037] The base 10 has any shape and is used to support and install the fixing block 13 and the first guide rail portion 31 and the second guide rail portion 32 .

[0038] The fixing block 13 is fixedly mounted on the base 10, for example, by bolting to achieve fixed connection. The fixing block 13 is provided with the movable hole 11, and the movable hole 11 penetrates the fixing block 13 along the second direction Y. During installation, the elastic pressing member 20 is first installed between the fixing block 13 and the base 12, and then the fixing block 13 and the base 12 are fixed.

[0039] Further, for convenience of installing the spring 22, as Figure 1 , Figure 4 As shown, a first positioning groove 2121 is provided on a side surface of the base 212 facing the base 10, and a second positioning groove 121 is provided on a position of the base 12 facing the movable hole 11. The first positioning groove 2121 and the second positioning groove 121 are located opposite to each other. One end of the spring 22 is disposed in the first positioning groove 2121, and the other end of the spring 22 is installed in the second positioning groove 121.

[0040] The shapes of the first positioning groove 2121 and the second positioning groove 121 are not limited. In this embodiment, they are circular grooves.

[0041] Furthermore, if Figure 1 As shown, in order to facilitate the workpiece to enter the positioning point, the positioning portion 211 is provided with a guiding inclined surface 2111 and a receiving surface 2112. The guiding inclined surface 2111 is inclined relative to the first direction X and the second direction Y, and is used to guide the workpiece entering the guide groove 40 to the receiving surface 2112 through the inclined surface. The receiving surface 2112 is closer to the top of the guide groove 40. Therefore, when the workpiece enters the receiving surface 2112 through the guiding inclined surface 2111, the workpiece is tightened under the action of the elastic tightening member 20, and its degree of freedom in the second direction Y is restricted, so that the workpiece is fixed.

[0042] The included angle between the guiding inclined surface 2111 and the second direction Y is an obtuse angle. The included angle between the guiding inclined surface 2111 and the first direction X is an acute angle.

[0043] The receiving surface 2112 may be a plane or a non-plane. In this embodiment, the receiving surface 2112 is a plane connected to the guiding inclined surface 2111 , and the receiving surface 2112 is parallel to the first direction X and perpendicular to the second direction Y.

[0044] Further, to facilitate the workpiece to enter the guide groove 40 and the positioning point, as Figure 2 As shown, the guide groove 40 includes a first groove portion 41 and a second groove portion 42. The width of the first groove portion 41 is greater than the width of the second groove portion 42. The width refers to the distance between the first guide rail portion 31 and the second guide rail portion 32. The elastic pressing member 20 is arranged at the bottom of the second groove portion 42. When the workpiece needs to be processed, the workpiece first enters the first groove portion 41 along the first direction X and then enters the second groove portion 42. In the second groove portion 42, the workpiece is pressed by the elastic pressing member 20 to achieve relative fixation of the position.

[0045] The width of the first groove portion 41 is greater than that of the second groove portion 42 , and a flared structure may be formed before the second groove portion 42 , thereby facilitating pushing the workpiece into the guide groove 40 .

[0046] like Figure 2 , Figure 5 As shown, in order to restrict the workpiece in the guide groove 40, protruding ridges 43 are provided on the opposite side walls of the guide groove 40. The ridges 43 are arranged along the first direction X and are spaced a certain distance from the bottom of the guide groove 40. The ridges 43 are spaced from each other to form a through space 50, which is connected to the inside of the guide groove 40. The ridges 43 can restrict the workpiece to prevent the workpiece from being ejected along the second direction Y.

[0047] The convex edge 43 is at least disposed at a position of the guide groove 40 opposite to the elastic pressing member 20, and the convex edge 43 can limit the workpiece at least at this position, so that the convex edge 43 can cooperate with the elastic pressing member 20 at this position to constrain the freedom of the workpiece in the second direction Y. In some embodiments, the convex edge 43 can be disposed in the entire length direction of the guide groove 40. In this embodiment, the convex edge 43 is disposed on the second groove portion 42.

[0048] Furthermore, in order to push the workpiece, the nut closing and positioning device of the utility model further includes a push rod 60. The push rod 60 is used to push the workpiece into or out of the guide groove 40. The push rod 60 is movably arranged along the first direction X and connected to the driving device. It can move along the first direction X and in the direction opposite to the first direction X under the drive of the driving device, so as to enter or exit the guide groove 40.

[0049] In order to facilitate pushing the nut, a recess 61 is provided on one side of the push rod 60 facing the guide groove 40 , and the recess 61 is in an inwardly concave arc shape.

[0050] When the nut closing and positioning device of the utility model is working, its working mode is as follows:

[0051] When the push rod 60 is located at the initial position, that is, outside the guide groove 40, the workpiece to be processed is placed into the starting end of the guide groove 40, that is, the starting position of the first groove portion 41;

[0052] The push rod 60 is driven by the driving device to move along the first direction X, thereby pushing the workpiece to the elastic pressing member 20; the workpiece enters the receiving surface 2112 along the guiding inclined surface 2111 of the elastic pressing member 20, and under the pushing of the elastic pressing member 20, the workpiece is pressed between the convex edge 43 of the limiting groove and the pushing plate 21 of the elastic pressing member 20;

[0053] The push rod 60 is driven by the driving device to move in a direction opposite to the first direction X, thereby withdrawing from the limiting groove and returning to the starting position, so as to facilitate the processing of the workpiece by the processing device;

[0054] The processing equipment located above the workpiece processes the workpiece; after the processing is completed, the processing equipment returns to its starting position;

[0055] Then repeat the above steps, the push rod 60 pushes the next workpiece into the guide groove 40, pushes the current workpiece along the first direction X to the position of the elastic guide member, and uses the current workpiece to push away the workpiece that has been processed in the previous step, thereby facilitating the processing of the current workpiece.

[0056] The utility model utilizes the elastic pressing member 20 to tighten and limit the workpiece, which can realize rapid loading and unloading of materials and greatly improve the processing efficiency.

[0057] Although the present invention is disclosed through the above embodiments, the scope of the present invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the present invention.
