[0039] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0040] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.
[0041] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In some descriptions of utility models, "a plurality of" means two or more, unless otherwise explicitly specified.
[0043] Combination Figure 1 and Figure 2 A limiting mechanism includes a first limiting member 110, a second limiting member 120, and a plurality of elastic pressing structures 140.
[0044] The first limiting member 110 and the second limiting member 120 are arranged opposite to each other, and a receiving space 130 is formed between the first limiting member 110 and the second limiting member 120. The receiving space 130 is used to receive the workpieces 500 stacked together. Specifically, the workpieces 500 can be sequentially loaded into the receiving space 130 and can be stacked together sequentially under the action of the receiving space 130.
[0045] In some embodiments, the workpiece 500 may have a portion of its structure located within the accommodating space 130, while the majority of its other structure may be located outside the accommodating space 130. For example, when the workpiece 500 is a ring-shaped structure such as a steel strip, one side of the steel strip may be located within the accommodating space 130. In other embodiments, the workpiece 500 may also be entirely located within the accommodating space 130.
[0046] Multiple elastic clamping structures 140 are respectively disposed on the first limiting member 110 near the second limiting member 120. The elastic clamping structures 140 are used to clamp the workpiece 500 onto the second limiting member 120 respectively.
[0047] Specifically, multiple elastic pressing structures 140 are spaced apart on the first limiting member 110 along the stacking direction of the workpieces 500 in the accommodating space 130, and the spacing between two adjacent elastic pressing structures 140 is adapted to the size of the workpieces 500, so that each elastic pressing structure 140 can press a corresponding workpiece 500 onto the second limiting member 120.
[0048] It is understood that the spacing between two adjacent elastic clamping structures 140 can be adapted to the height dimension of the workpiece 500 (which is also the dimension of the workpiece 500 in the stacking direction). In this way, when the workpieces 500 are loaded one by one into the accommodating space 130, the workpieces 500 can be stacked together. At this time, each elastic clamping structure 140 can correspond exactly to one workpiece 500 and elastically clamp the workpiece 500 onto the second limiting member 120.
[0049] In the aforementioned limiting mechanism 100, a first limiting member 110 and a second limiting member 120 are arranged opposite to each other, forming an accommodating space 130 between the first limiting member 110 and the second limiting member 120. On the side of the first limiting member 110 near the second limiting member 120, multiple elastic pressing structures 140 are respectively arranged at intervals along the stacking direction of the workpieces 500 in the accommodating space 130. This allows the elastic pressing structures 140 to elastically press each workpiece 500 stacked together in the accommodating space 130 onto the second limiting member 120, thereby positioning each workpiece 500 stacked together in the accommodating space 130. In this way, there will be no gap between the workpiece 500 and the first limiting member 110 and the second limiting member 120 in the accommodating space 130, ensuring the stability of the stacked workpieces 500.
[0050] See Figure 3 The elastic structure may include a clamping member 141 and an elastic member (not shown in the figure). The clamping member 141 is disposed on the first limiting member 110 through the elastic member. Under the action of the elastic member, the clamping member 141 presses the workpiece 500 on the second limiting member 120.
[0051] Furthermore, during the process of loading the workpiece 500 into the accommodating space 130 and removing the workpiece 500 from the accommodating space 130, the portion of the clamping member 141 that contacts the workpiece 500 is configured as a guide slope.
[0052] Understandably, the clamping member 141 can move towards the second limiting member 120 under the action of the elastic member to press the workpiece 500 against the second limiting member 120. Therefore, the clamping member 141 is located in the accommodating space 130 under the action of the elastic member. Thus, when the workpiece 500 is loaded into the accommodating space 130 or when the workpiece 500 is taken out of the accommodating space 130, the clamping member 141 will block the workpiece 500. Therefore, setting the part of the clamping member 141 that contacts the workpiece 500 as a guide slope can make the workpiece 500 generate a pushing force on the clamping member 141 when it is loaded or taken out, so that the clamping member 141 can drive the elastic member to contract, which facilitates the loading and unloading of the workpiece 500.
[0053] For example, the portion of the clamping member 141 located in the accommodating space 130 can be made into an arc surface, or the portion of the clamping member 141 located in the accommodating space 130 can be made into a spherical surface. In this way, the portion of the clamping member 141 that contacts the workpiece 500 is an arc surface, which facilitates the loading and unloading of the workpiece 500, and also facilitates the relative movement between the workpiece 500 and the clamping member 141 when the clamped workpiece 500 is moved.
[0054] Furthermore, in order to facilitate the connection between the clamping member 141 and the first limiting member 110 via the elastic member, the elastic clamping structure 140 may also include a mounting base 142. The mounting base 142 is provided with a guide groove (not shown in the figure), the clamping member 141 is disposed in the guide groove, and an elastic member is provided between the part of the clamping member 141 in the guide groove and the mounting base 142. The mounting base 142 is connected to the first limiting member 110.
[0055] Specifically, during assembly, the clamping member 141 can be first set on the mounting base 142 through the elastic member to form the whole of the elastic clamping structure 140, and then the whole is set on the first limiting member 110 through the mounting base 142.
[0056] In addition, the mounting base 142 is provided with a guide groove, and the clamping member 141 is disposed in the guide groove. The guide groove can guide the clamping member 141 when it is subjected to the elastic force of the elastic member and the thrust applied by the workpiece 500, so as to ensure the stability of the movement of the clamping member 141.
[0057] See Figure 2 In some embodiments, a mounting hole 111 may be provided on the first limiting member 110, and the mounting base 142 is disposed in the mounting hole 111.
[0058] Understandably, during assembly, the mounting base 142 can be housed within the mounting hole 111, with only a portion of the clamping member 141 exposed above the first limiting member 110. This reduces the space occupied by the elastic clamping structure 140 in the accommodating space 130, allowing the first limiting member 110 to be positioned closer to the second limiting member 120. While ensuring that the accommodating space 130 can accommodate the workpiece 500, the width of the accommodating space 130 is minimized, which is beneficial for the accommodating space 130 to limit the workpiece 500. At the same time, the limiting mechanism 100 can be made more compact.
[0059] Furthermore, the mounting base 142 is also provided with a fixing hole 112 communicating with the mounting hole 111, and the fixing hole 112 is perpendicular to the mounting hole 111. The fixing hole 112 is used to install a locking member to fix the mounting base 142 in the mounting hole 111. The locking member can be a ferrule, which can be used to press the mounting base 142 against the mounting hole 111 to fix the mounting base 142. The above structure facilitates…
[0060] See Figure 1 and Figure 2 The limiting mechanism 100 may also include a support structure 150, which is used to connect with the first limiting member 110 to provide support for the first limiting member 110.
[0061] Furthermore, the support structure 150 may include a support column 151 and a connector 152. The support column 151 is disposed on one side of the first limiting member 110 and extends along the stacking direction of the workpiece 500. One end of the connector 152 is connected to the first limiting member 110, and the other end of the connector 152 is connected to the support column 151, and its position can be adjusted along the extending direction of the support column 151.
[0062] Specifically, since the support column 151 extends along the stacking direction parallel to the workpiece 500, by changing the position of the connector 152 in the extension direction of the support column 151, the position of the first limiting member 110 connected to the connector 152 in the direction parallel to the stacking direction of the workpiece 500 can be changed.
[0063] It is understood that by changing the position of the first limiting member 110, the position of each elastic pressing structure 140 on the first limiting member 110 can be changed, so as to ensure that each elastic pressing structure 140 can accurately press the corresponding workpiece 500 onto the second limiting member 120. For example, by adjusting the position of the elastic pressing structure 140 by the first limiting member 110, each elastic pressing structure 140 can be pressed precisely onto the center of the workpiece 500 and onto the second limiting member 120. In this way, even if there are dimensional errors or gaps between the stacked workpieces 500, it can still be ensured that each elastic pressing structure 140 can accurately press the corresponding workpiece 500 onto the second limiting member.
[0064] In some embodiments, the connector 152 can be a locking block, one end of which can be fixedly connected to the first limiting member 110 structure, and the other end of which can be adjusted to be connected to the support column 151 by locking.
[0065] See Figure 4 This application also provides a feeding device, including a base 200, a feeding mechanism 300, and a limiting mechanism 100 as described in the embodiments of this application. The feeding mechanism 300 and the limiting mechanism 100 are disposed on the base 200. The feeding mechanism 300 is vertically and flexibly disposed on the base 200. The workpiece 500, which is accommodated in the accommodating space 130, is supported by the feeding mechanism 300, and the feeding mechanism 300 can drive the workpiece 500 to move along its stacking direction to realize the feeding of the workpiece 500.
[0066] It is understood that the feeding mechanism 300 can support the bottom layer of workpieces 500 stacked in the accommodating space 130. When the feeding mechanism 300 moves the workpieces 500 along their stacking direction, it can move the top layer of workpieces 500 out of the accommodating space 130 to realize the feeding of workpieces 500.
[0067] It should also be noted that the feeding device adopts the limiting mechanism 100 in the embodiment of this application. Therefore, when the feeding mechanism 300 drives the workpiece 500 to move, each workpiece 500 will not tilt or cross with adjacent workpieces 500 during movement, and the feeding stability of the workpiece 500 is high.
[0068] See Figure 1 In some embodiments, the workpiece 500 is a ring structure, such as a steel strip. In order to ensure the stability of the overall feeding of the ring structure workpiece 500, the feeding device may include multiple limiting mechanisms 100, and at least one set of opposite sides of the workpiece 500 are respectively accommodated in the accommodating space 130.
[0069] Furthermore, the feeding device may also include a positioning mechanism 400, which is disposed opposite to the base 200 along a first direction, and a limiting mechanism 100 is disposed opposite to the base 200 along a second direction. The positioning mechanism 400 can be used to position the first pair of sides of the workpiece 500, and the second pair of sides of the workpiece 500 are accommodated within the accommodating space 130. The second pair of sides are adjacent to the first pair of sides, and the first direction is perpendicular to the second direction.
[0070] In some embodiments, the positioning mechanism 400 can be used to abut against the inner surface of the first opposite sides of the workpiece 500 to position the workpiece 500 in a first direction. In other embodiments, the positioning mechanism 400 can also be used to abut against the outer surface of the first opposite sides of the workpiece 500 to position the workpiece 500 in a first direction.
[0071] The positioning mechanism 400 can be a positioning rod extending in a direction parallel to the stacking direction of the workpiece 500.
[0072] In addition, the limiting mechanism 100 is disposed on the base 200 in the second direction, so that the two sides of the second opposite side of the workpiece 500 can be respectively accommodated in the corresponding accommodating space 130. The elastic pressing structure 140 on each limiting mechanism 100 presses the workpiece 500 on the second limiting member 120, thereby realizing the positioning of the workpiece 500 in the second direction.
[0073] See Figure 4 The feeding mechanism 300 may include a feeding drive structure 310, a support member 320, a transmission member 330, and a guide rod 340.
[0074] The guide rod 340 is mounted on the base 200 and can be located inside the workpiece 500 of the annular structure.
[0075] The support member 320 is movably sleeved on the guide rod 340, and the support member 320 is used to support the workpiece 500, while the guide rod 340 is used to guide the support member 320 when it moves.
[0076] The feeding drive structure 310 is driven to connect with the transmission component 330. The feeding drive structure 310 is used to drive the transmission component 330 to contact and abut against the support component 320, and to drive the support component 320 to move in a direction parallel to the stacking direction of the workpiece 500. The feeding drive structure 310 can be a lead screw drive structure.
[0077] It is understandable that the support member 320 can be moved by contacting and resisting with the transmission member 330, which makes it easy to replace the support member 320.
[0078] Furthermore, the support member 320 is provided with a clearance groove 321, and at least part of the positioning mechanism 400 and / or limiting mechanism 100 is located within the clearance groove 321.
[0079] It is understood that a clearance groove 321 is provided on the support member 320, and at least part of the positioning mechanism 400 and / or the limiting mechanism 100 is located in the clearance groove 321. In this way, it can be ensured that the support member 320 has a sufficiently large support surface to support the workpiece 500 to ensure the stability of moving the workpiece 500. At the same time, the support member 320 can also avoid interference with the positioning mechanism 400 and / or the limiting mechanism 100 when moving.
[0080] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of some utility models should be included within the protection scope of some utility models.
