[0034] Such as Figure 1-2As shown, in an embodiment of a positioning mechanism, the positioning mechanism includes a support member 1, a first clamping assembly, and a second clamping assembly. A placement groove 11 for placing a workpiece is formed in the support member 1. The placement groove 11 has a first side wall 111 and a first end wall 112 that are arranged at an angle. The first clamping assembly includes a first clamping module 21 and a first driving module. At least a part of the first clamping module 21 is located within the area of the placement groove 11. The output end of the first driving module is connected to the first clamping module 21 and is used to drive the first clamping module 21 to approach or move away from the first side wall 111. The second clamping assembly includes a second clamping module 31 and a second driving module. At least a part of the second clamping module 31 is located within the area of the placement groove 11. The output end of the second driving module is connected to the second clamping module 31 and is used to drive the second clamping module 31 to approach or move away from the first end wall 112.

[0035] In this embodiment, a first driving module is provided in the first clamping assembly. The first clamping module 21 can first approach the first side wall 111 under the drive of the first driving module, achieving the effect of avoiding interference to facilitate the placement of the workpiece into the placement groove 11. Then, the first clamping module 21 is driven to move away from the first side wall 111 and press against the workpiece. Similarly, the second clamping module 31 can press against the workpiece under the drive of the second driving module, cooperating with the inner wall of the placement groove 11, thereby being able to position and fix the workpiece and avoid deviation during the processing, solving the technical problem that the deviation of the workpiece during processing affects the processing effect.

[0036] In a specific embodiment of the first driving module, the first driving module includes a first driving module 22 and a first reset member 23. The output end of the first driving module 22 is connected to the first clamping module 21. The movement of the first driving module 22 driving the first clamping module 21 to approach the first side wall 111 can store energy in the first reset member 23, and the release of the stored energy in the first reset member 23 can cause the first clamping module 21 to press against the workpiece.

[0037] In this embodiment, by providing the first reset member 23, an automatic rebound effect can be achieved, enabling the first clamping module 21 to elastically abut against the workpiece. This can not only reduce energy consumption but also achieve a better clamping effect. Moreover, the first reset member 23 can be set to be in an energy storage state when the first clamping module 21 abuts against the workpiece, which can improve the effect of avoiding deviation.

[0038] In a specific embodiment of the second driving module, the second driving module includes a second driving module 32 and a second reset member 33. The output end of the second driving module 32 is connected to the second clamping module 31. The movement of the second driving module 32 driving the second clamping module 31 to approach the first end wall 112 can store energy in the second reset member 33, and the release of the stored energy in the second reset member 33 can cause the second clamping module 31 to press against the workpiece.

[0039] In this embodiment, similar to the previous embodiments, by providing the second reset member 33, an automatic spring-back effect can be achieved, enabling the second clamping module 31 to elastically abut against the workpiece. This can not only reduce energy consumption but also achieve a better clamping effect. Moreover, the second reset member 33 can be arranged in a state of storing energy when the second clamping module 31 abuts against the workpiece, which can improve the effect of preventing deviation.

[0040] Specifically in combination with the previous embodiments, both the first reset member 23 and the second reset member 33 can be springs. Additionally, in a specific embodiment where the first drive module and the second drive module are applied simultaneously, the effect of automatically resetting and clamping the workpiece can be achieved simultaneously.

[0041] In an embodiment of the positioning mechanism, the number of the placement grooves 11 is multiple, and the placement grooves 11 are arranged at intervals on the support member 1.

[0042] In this embodiment, by providing multiple placement grooves 11, multiple workpieces can be placed, facilitating one-time processing positioning or batch positioning and fixing.

[0043] It can be understood that when the shape of the placement groove 11 is generally rectangular, the placement groove 11 can have opposite first side walls 111 and second side walls, as well as opposite first end walls 112 and second end walls. The shape of the placement groove 11 is preferably matched with the shape of the workpiece. For example, when there are protrusions on the side of the workpiece, corresponding grooves are provided.

[0044] In an embodiment of the positioning mechanism, the number of the first clamping modules 21 is multiple, and each first clamping component is arranged in one-to-one correspondence with each placement groove 11. And / or, the number of the second clamping modules 31 is multiple, and each second clamping component is arranged in one-to-one correspondence with each placement groove 11.

[0045] In this embodiment, when multiple first clamping modules 21 are provided, one side wall of the workpiece can be clamped simultaneously. When multiple second clamping modules 31 are provided, one end of the workpiece can be clamped simultaneously. And when both multiple first clamping modules 21 and multiple second clamping modules 31 are provided, multiple workpieces can be positioned and fixed simultaneously, thereby improving the positioning efficiency. Cooperating with multiple processing mechanisms, multiple workpieces can be processed simultaneously.

[0046] In an embodiment of the positioning mechanism, the first clamping component further includes a first connecting member 24, the first clamping module 21 is arranged on the first connecting member 24, and the output end of the first drive module is connected to the first connecting member 24. And / or, the second clamping component further includes a second connecting member, the second clamping module 31 is arranged on the second connecting member, and the output end of the second drive module is connected to the second connecting member.

[0047] In this embodiment, different from the previous embodiments, in the previous embodiments, multiple first clamping components and / or multiple second clamping components were provided, that is, multiple were individual drive sources. In this embodiment, by providing a first connecting member 24, the first clamping modules 21 can all be arranged on the first connecting member 24, so as to share a first drive module. Similarly, the second clamping modules 31 are all arranged on the second connecting member, so as to share a second drive module.

[0048] In an embodiment of the positioning mechanism, a first hole 113 is formed at the bottom of the placement groove 11, and a second hole 12 communicating with the placement groove 11 is formed at a position on the support member 1 close to the first end wall 112. The first clamping module 21 passes through the first hole 113, and the second clamping module 31 passes through the second hole 12.

[0049] Combined with the previous embodiments, the shape of the placement groove 11 is preferably matched with the shape of the workpiece. Taking the workpiece as a rectangular shape as an example, in order to improve the matching degree with the workpiece, generally one side wall of the placement groove 11 is set to match the size and shape of the workpiece, and the distance between the end walls of two adjacent side walls is slightly larger than the length of the workpiece, so as to facilitate the placement of the workpiece. However, the margin is small and not enough to place the clamping module. Therefore, in this embodiment, by providing a first hole 113 at the bottom of the placement groove 11 and a second hole 12 at a position on the support member 1 outside the placement groove 11 and close to the first end wall 112, it is possible to facilitate the matching of the shape of the placement groove 11 with the workpiece, so as to achieve a better positioning and fixing effect. It can be understood that the depth of the placement groove 11 is less than the thickness of the workpiece, and the clamping module passing through the second hole 12 has a protrusion facing the placement groove 11 and capable of extending into the placement groove 11, so that it can abut against the workpiece.

[0050] In an embodiment of the positioning mechanism, the first drive module includes a first mounting seat 221, a transmission member 222, and a third drive member 223. The transmission member 222 is slidably mounted on the first mounting seat 221 and is connected to the first clamping module 21. One end of the first reset member 23 is connected to the first mounting seat 221, and the other end is connected to the transmission member 222. The third drive member 223 can drive the transmission member 222 to slide.

[0051] In this embodiment, specifically, the first mounting seat 221 can be L-shaped, so as to form a space separated from the transmission member 222. The transmission member 222 can be sleeved on a shaft for sliding, and the first reset member 23 is also sleeved on the shaft. In addition, combined with the previous embodiments, in this embodiment, by providing the transmission member 222, it is convenient to connect the transmission member 222 with the first connecting member 24. Both the transmission member 222 and the first connecting member 24 play a transmission role to drive the movement of the first clamping module 21 on the first connecting member 24.

[0052] In an embodiment of the positioning mechanism, the driving direction of the third driving member 223 is perpendicular to the sliding direction of the transmission member 222. The end face of the transmission member 222 facing the third driving member 223 is the first inclined surface 211, and the first inclined surface 211 is arranged at an acute angle with the sliding direction of the transmission member 222.

[0053] In this embodiment, by setting the driving direction of the third driving member 223 to be perpendicular to the sliding direction of the transmission member 222, when the third driving member 223 approaches the transmission member 222 from the distal end away from the transmission member 222 and contacts the transmission member 222, the inclined surface is used to drive the transmission member 222 to slide relative to the first mounting seat 221. In this way, the layout structure can be optimized, the effect of a compact layout can be achieved, and thus the usage space can be reduced.

[0054] It can be understood that the sliding direction of the transmission member 222 is the Figure 1 X direction in the attached

[0055] In an embodiment of the positioning mechanism, the second driving module includes a second mounting seat 321 and a second driving member 322. The second clamping module 31 is slidably connected to the second mounting seat 321. One end of the second reset member 33 is connected to the second mounting seat 321, and the other end is connected to the second clamping module 31. The second driving member 322 can drive the second clamping module 31 to slide.

[0056] In this embodiment, specifically, the second mounting seat 321 can be L-shaped, so that a space separated from the second clamping module 31 can be formed. The second clamping module 31 can be sleeved on a shaft to slide, and the second reset member 33 is also sleeved on the shaft. Different from the previous embodiment, in this embodiment, the second driving member 322 directly drives the second clamping module 31, so that the second connecting member can be not provided. When it is necessary to cooperate with a plurality of placement slots 11 to position and fix a plurality of workpieces, the number of second clamping components needs to be set to be multiple.

[0057] In an embodiment of the positioning mechanism, the driving direction of the second driving member 322 is perpendicular to the sliding direction of the second clamping module 31. The end face of the second clamping module 31 facing the second driving member 322 is the second inclined surface 311, and the second inclined surface 311 is arranged at an acute angle with the sliding direction of the second clamping module 31.

[0058] In this embodiment, by setting the driving direction of the second driving member 322 to be perpendicular to the sliding direction of the second clamping module 31, when the second driving member 322 approaches the second clamping module 31 from the distal end away from the second clamping module 31 and contacts the second clamping module 31, the inclined surface is used to drive the second clamping module 31 to slide relative to the second mounting seat 321. In this way, the layout structure can be optimized, the effect of a compact layout can be achieved, and thus the usage space can be reduced.

[0059] Combined with the previous embodiments, taking the moving direction of the first clamping module 21 as the X direction and the moving direction of the second clamping module 31 as the Y direction as an example, the driving directions of the third driving member 223 and the second driving member 322 can both be the Z direction. Preferably, the first clamping module 21 includes a plurality of clamping blocks arranged along the Y direction, so as to better position and fix the side of the workpiece. Since the second clamping module 31 abuts against the end side of the workpiece, it may include one clamping block. When the end side is relatively long, a plurality of clamping blocks may also be provided.

[0060] It can be understood that the sliding direction of the second clamping module 31 is the Figure 1 Y direction in the figure.

[0061] The present invention also relates to a processing device, including the positioning mechanism in the previous embodiments. The processing device further includes a processing component for processing the workpiece on the support member 1.

[0062] By adopting the positioning mechanism in the above embodiments, better positioning and fixing effects can be achieved, preventing the workpiece from shifting during the processing. Specifically, the processing device can be a welding device, and the processing component can be a welding component. By applying the positioning mechanism of the present invention in the welding field, it is possible to prevent the workpiece from shifting during welding, thereby improving the welding quality.

[0063] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0064] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
