Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically a bidirectional clamping device. Background Technology

[0002] In manual welding, drilling, screw driving, and other processes, using fixtures to clamp the workpiece can improve the stability of the operation and the product yield.

[0003] The most common type of clamp is the standard elbow clamp, which can only clamp on one side. Therefore, elbow clamps need to be set around the product to be processed (at least on both sides) to achieve the clamping function. Since setting up multiple elbow clamps requires more installation space and working space, and also does not improve work efficiency, those skilled in the art have been continuously striving to find clamps with small working space requirements and high work efficiency. Utility Model Content

[0004] In order to overcome the defects in the prior art, this utility model provides a bidirectional clamping device, which is easy to install and operate and improves work efficiency.

[0005] This application discloses a bidirectional clamping device, comprising:

[0006] The clamping seat has a first receiving cavity for accommodating the product, the first receiving cavity including a first clamping plate and a second clamping plate disposed opposite to each other;

[0007] The movable clamping plate extends into the first receiving cavity and clamps the product together with the first clamping plate or the second clamping plate.

[0008] A cam drive mechanism includes a cam seat, a cam mounted on the cam seat via a rotating shaft, a drive assembly that is penetrated by the rotating shaft and movably connected to the cam, and a swing arm connected to the rotating shaft. The movable clamp is connected to the drive assembly.

[0009] Specifically, the clamping seat further includes a base plate, and the first clamping plate and the second clamping plate are disposed opposite to each other on the base plate, and the base plate, the first clamping plate and the second clamping plate form the first receiving cavity.

[0010] Specifically, the base plate is provided with a first slide groove and a second slide groove that are interconnected. At least a portion of the drive assembly extends into the first slide groove. One end of the movable clamp is located above the second slide groove, and the other end of the movable clamp extends into the second slide groove and extends into the first slide groove to connect with the drive assembly.

[0011] Specifically, the drive assembly includes a first sliding plate, a second sliding plate, and a connector for connecting the first sliding plate and the second sliding plate. The first sliding plate is slidably connected to the cam seat. The first sliding plate is provided with a second receiving cavity. The rotating shaft passes through the second receiving cavity and the cam is installed in the second receiving cavity. The second sliding plate is connected to the movable clamping plate.

[0012] Specifically, the cam seat is provided with a third sliding groove, and the first sliding plate is disposed in the third sliding groove.

[0013] Specifically, the cam seat is further provided with a third receiving cavity that communicates with the third slide groove, and the swing arm is rotatably disposed in the third receiving cavity.

[0014] Specifically, the third receiving cavity has a mounting hole on the wall facing the clamping seat. A damping post and a spring are provided in the mounting hole. One end of the damping post is located outside the mounting hole to abut against the swing arm, and the other end of the damping post located inside the mounting hole abuts against the spring.

[0015] Specifically, the connector includes a first connecting rod, a second connecting rod, and a floating joint for connecting the first connecting rod and the second connecting rod. The other end of the first connecting rod is connected to the first sliding plate, and the other end of the second connecting rod is connected to the second sliding plate.

[0016] Specifically, a handle is also connected to the end of the swing arm that is away from the pivot.

[0017] Specifically, the device also includes a base, on which the clamping seat and the cam drive mechanism are both mounted.

[0018] This utility model has at least the following beneficial effects:

[0019] 1. The required installation and operating space is small. Especially when there is only one side of the working environment with installation and operating space and no space on the other side, the bidirectional clamping device of this solution can solve the clamping problem of the product to be processed.

[0020] 2. The clamping device of this solution drives the movable clamping plate to move between the first clamping plate and the second clamping plate through the drive component. When the movable clamping plate and the first clamping plate cooperate to clamp the first product, the second product to be processed can be placed between the second clamping plate and the movable clamping plate at the same time. Thus, when the drive component drives the movable clamping plate away from the first clamping plate to release the processed first product, the movable clamping plate can move further to cooperate with the second clamping plate to clamp the second product, which effectively improves work efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "fixing," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "below," and "over" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "rear", "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 application 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 limiting the scope of protection of this application.

[0035] Furthermore, the terms "first" and "second" are used only to distinguish between different terms in description and do not have any special meaning.

[0036] Combination Figures 1 to 3As shown, the bidirectional clamping device of this embodiment mainly includes: a clamping seat 1, a movable clamping plate 2, and a cam drive mechanism 3. The clamping seat 1 has a first receiving cavity for accommodating the product to be processed. This first receiving cavity includes a first clamping plate 11 and a second clamping plate 12 disposed opposite to each other. The movable clamping plate 2 extends into the first receiving cavity. Driven by the cam drive mechanism 3, the movable clamping plate 2 approaches the first clamping plate 11 or the second clamping plate 12, thereby clamping the product to be processed together with the first clamping plate 11 or the second clamping plate 12. Specifically, the cam drive mechanism 3 includes: a cam seat 31, a rotating shaft 32, a cam 33, a drive assembly, and a swing arm 35; the rotating shaft 32 is rotatably connected to the cam seat 31, and the rotating shaft 32 passes through both the cam 33 and the drive assembly. The cam 33 is fixedly connected to the rotating shaft 32, and the drive assembly is movably connected to the cam 33. That is, the drive assembly can move linearly relative to the rotating shaft 32 and the cam seat 31. The movable clamping plate 2 is connected to the drive assembly and can move linearly with the drive assembly, thereby driving the movable clamping plate 2 to approach the first clamping plate 11 or the second clamping plate 12.

[0037] By adopting the above solution, the bidirectional clamping device of this embodiment has the following advantages:

[0038] 1. The required installation and operating space is small. Especially when there is only one side of the working environment with installation and operating space and no space on the other side, the bidirectional clamping device of this solution can solve the clamping problem of the product to be processed.

[0039] 2. The clamping device of this solution drives the movable clamping plate 2 to move between the first clamping plate 11 and the second clamping plate 12 via a drive assembly. When the movable clamping plate 2 and the first clamping plate 11 cooperate to clamp the first product, the second product to be processed can be placed between the second clamping plate 12 and the movable clamping plate 2 at the same time. Thus, when the drive assembly drives the movable clamping plate 2 away from the first clamping plate 11 to release the processed first product, the movable clamping plate 2 can move further to cooperate with the second clamping plate 12 to clamp the second product, effectively improving work efficiency.

[0040] like Figure 2 and Figure 3 As shown, the clamping seat 1 in this embodiment also includes a base plate 13. A first clamping plate 11 and a second clamping plate 12 are disposed opposite to each other on the base plate 13. The first clamping plate 11, the second clamping plate 12, and the base plate 13 together form the aforementioned first receiving cavity for accommodating the product. When the movable clamping plate 2 and the first clamping plate 11 jointly clamp the product, the distance between the movable clamping plate 2 and the second clamping plate 12 is greater than the distance between the movable clamping plate 2 and the first clamping plate 11, and vice versa. This facilitates the loading and unloading of the product to be processed.

[0041] like Figure 2 and Figure 3As shown, the base plate 13 of this embodiment is provided with a first sliding groove 131 and a second sliding groove 132 that are interconnected. At least a portion of the drive assembly extends into the first sliding groove 131, and one end of the movable clamp 2 is located above the second sliding groove 132, while the other end extends into the second sliding groove 132 and into the first sliding groove 131 to connect with the drive assembly. Specifically, the first sliding groove 131 is preferably horizontally arranged and can pass through both ends of the base 4; the second sliding groove 132 is preferably vertically arranged, and its center can coincide with the center of the first receiving cavity.

[0042] Combination Figures 4 to 6 As shown, the driving assembly of this embodiment includes a first sliding plate 341, a second sliding plate 342, and a connector 343. The connector 343 is used to connect the first sliding plate 341 and the second sliding plate 342. The first sliding plate 341 is slidably connected to the cam seat 31 and has a second receiving cavity 3411. The aforementioned rotating shaft 32 passes through the second receiving cavity 3411 to connect the cam 33 located in the second receiving cavity 3411. The outer wall of the cam 33 abuts against the inner wall of the second receiving cavity 3411, thereby realizing the driving of the first sliding plate 341 (that is, the driving assembly) by the cam 33. The end of the second sliding plate 342 facing away from the connector 343 passes through the aforementioned first sliding groove 131 and is connected to the movable clamping plate 2.

[0043] like Figure 7 As shown, the cam seat 31 of this embodiment is provided with a third slide groove 311, and the first sliding plate 341 of the drive assembly is slidably disposed within the third slide groove 311. Preferably, the third slide groove 311 also extends through both ends of the cam seat 31. Further, the cam seat 31 is also provided with a third receiving cavity 312 communicating with the third slide groove 311, and the rocker arm 35 is disposed within the third receiving cavity 312. The third receiving cavity 312 has only one wall surface, with the rest open, to ensure that the rocker arm 35 can rotate within the third receiving cavity 312, and the two ends of the wall surface can also appropriately restrict the rotation of the rocker arm 35.

[0044] Furthermore, such as Figure 7 As shown, the third receiving cavity 312 of this embodiment has a mounting hole 313 on the wall surface (i.e., the aforementioned wall surface) facing the clamping seat 1. Figure 2 As shown, a damping post 36 and a spring 37 are provided inside the mounting hole 313. One end of the damping post 36 is located outside the mounting hole 313 to abut against the rocker arm 35, and the other end is located inside the mounting hole 313, where it abuts against the spring 37. Specifically, the mounting hole 313 can be a through hole or a blind hole. When the mounting hole 313 is a through hole, a baffle 38 needs to be provided on the cam seat 31 to limit the movement of the spring 37 (e.g., ...). Figure 2 and Figure 6 (As shown).

[0045] like Figure 4 and Figure 6 As shown, the connector 343 in this embodiment includes: a first connecting rod 3431, a second connecting rod 3432, and a floating joint 3433 for connecting the two. The end of the first connecting rod 3431 facing away from the floating joint 3433 is connected to the first sliding plate 341, and the end of the second connecting rod 3432 facing away from the floating joint 3433 is connected to the second sliding plate 342.

[0046] like Figure 6 As shown, the swing arm 35 in this embodiment is also provided with a handle 39 on the end opposite to the pivot 32 for operation by personnel.

[0047] like Figure 1 As shown, the bidirectional clamping device in this embodiment also includes a base 4, on which the clamping seat 1 and the cam drive mechanism 3 are both mounted.

[0048] Preferably, the cam 33 is provided with a mechanical dead point, which can realize three positions: the middle position (the distance between the movable clamping plate 2 and the first clamping plate 11 and the second clamping plate 12 is equal, and the product is not clamped), the front clamping position (the movable clamping plate 2 and the first clamping plate 11 clamp the product together), and the rear clamping position (the movable clamping plate 2 and the second clamping plate 12 clamp the product together).

[0049] In summary, the working process of the bidirectional clamping device in this embodiment is as follows: the first product is placed between the first clamping plate 11 and the movable clamping plate 2, and the operator swings the swing arm 35 to clamp the first product with the movable clamping plate 2. Before the first product is finished or removed, the second product is placed between the second clamping plate 12 and the movable clamping plate 2. When the operator rotates the swing arm 35 to remove the first product, the second product can be clamped at the same time. The above actions are repeated.

[0050] This utility model uses specific embodiments to illustrate the principle and implementation of the utility model. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
