Description

Technical Field

[0001] This utility model relates to the technical field of parts clamping, and in particular to a clamping mechanism. Background Technology

[0002] In recent years, with the increasing demand for high-precision machining in fields such as new energy vehicles and aerospace, parts clamping devices have become core tooling equipment to ensure machining accuracy and efficiency, and their performance directly affects product quality and production stability.

[0003] For example, Chinese utility model patent CN202021350710.4 describes a part thickness clamping mechanism. By connecting the component and forming a floating gap between the bottom of the groove and the floating pressure block, it can adapt to the clamping operation of parts of different thicknesses. However, it is inconvenient to fix the parts placed on the support block, which makes it easy for the parts on the support block to shift when clamping the parts, resulting in clamping failure and reducing the working efficiency of the clamping mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a clamping mechanism to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] A clamping mechanism includes a clamping assembly, the clamping assembly comprising: a support block disposed on the top of a mounting base; a cylinder disposed on one side of the support block; a connector disposed on the top of the cylinder; a pressure block disposed on the bottom of the connector and located above the support block; a fixing assembly disposed on the top of the support block, the fixing assembly comprising: a rotating rod passing through the outside of the support block and rotatably connected to the support block; a bevel gear disposed at one end of the rotating rod and located inside the support block; a double-threaded rod passing through the bevel gear; a movable block sleeved on the outside of the double-threaded rod and passing through the top of the support block, the top of the support block having a through groove for engaging the movable block; and a clamping frame disposed on the top of the movable block and located on the top of the support block.

[0007] Optionally, the outer side of the rotating rod is provided with a thread, and a threaded sleeve is provided on the thread and sleeved on the outer side of the rotating rod.

[0008] Optionally, a compression plate is provided on one side of the threaded sleeve and is located outside the support block.

[0009] Optionally, an anti-slip pad is provided between the extrusion plate and the support block.

[0010] Optionally, the bottom of the clamping frame is provided with a slider, and the top of the support block is provided with a groove that cooperates with the slider.

[0011] Optionally, a silicone pad is provided on the inner side of the clamping frame.

[0012] Optionally, a positioning rod is provided at the bottom of the pressure block, and a through hole is provided on the support block to cooperate with the positioning rod.

[0013] Optionally, the bottom of the positioning rod is provided with a limiting plate that matches the through hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By rotating the rotating rod, the rotating rod meshes with the double-threaded rod through a bevel gear, causing the double-threaded rod to rotate. The rotating double-threaded rod drives the moving block to move relative to the double-threaded rod. The moving block moves relative to the rod, causing the clamping frame to clamp the outside of the support block, thus clamping and fixing the position of the support block and increasing the stability of the support block placed on top of the support block.

[0023] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to 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.

[0024] 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 the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Given that in the current technology, it is inconvenient to fix the parts placed on the support block, the parts on the support block are prone to displacement when the parts are clamped, resulting in failure to clamp the parts and thus reducing the working efficiency of the clamping mechanism.

[0026] like Figure 1-3 As shown, this utility model embodiment provides a clamping mechanism, including a clamping assembly 1. The clamping assembly 1 includes: a support block 12 disposed on the top of a mounting base 11; a cylinder 13 disposed on one side of the support block 12; a connector 14 disposed on the top of the cylinder 13; a pressure block 15 disposed on the bottom of the connector 14 and located above the support block 12; and a fixing assembly 2 disposed on the top of the support block 12. The fixing assembly 2 includes: a rotating rod 21 passing through the outside of the support block 12 and rotatably connected to the support block 12; a bevel gear 22 disposed at one end of the rotating rod 21 and located inside the support block 12; a bidirectional threaded rod 23 passing through the bevel gear 22; a moving block 231 sleeved on the outside of the bidirectional threaded rod 23 and passing through the top of the support block 12, the top of the support block 12 being provided with a through groove 232 that mates with the moving block 231; and a clamping frame 24 disposed on the top of the moving block 231 and located on the top of the support block 12.

[0027] In use, the part is placed on top of the support block 12, and then the rotating rod 21 is rotated. The rotating rod 21 is connected to the double-threaded rod 23 through the bevel gear 22, which drives the double-threaded rod 23 to rotate. The rotating double-threaded rod 23 drives the moving block 231 to move relative to the double-threaded rod 23. The moving block 231 drives the clamping frame 24 to clamp the outside of the support block 12, thereby clamping and fixing the position of the support block 12 and increasing the stability of the support block 12 placed on top of the support block 12. Finally, the cylinder 13 is activated. The cylinder 13 pushes the pressure block 15 downward through the connecting piece 14, thereby pressing the part on the support block 12.

[0028] Specifically, the parts are rectangular automotive components and thin-walled parts (such as housings and welded parts).

[0029] Specifically, the bidirectional threaded rod 23 is threadedly connected to the movable block 231.

[0030] Specifically, the structure of connector 14 is an L-shaped steel plate.

[0031] Furthermore, the outer side of the rotating rod 21 is provided with a thread 25, and a threaded sleeve 251 is provided on the thread 25 and sleeved on the outer side of the rotating rod 21. When the rotating rod 21 is rotated to push the clamping frame 24 to clamp the fixed support block 12, the threaded sleeve 251 is rotated. The rotating threaded sleeve 251 moves and squeezes towards the outer wall of the support block 12 through the thread 25, thereby squeezing and locking the rotating rod 21.

[0032] Furthermore, a pressing plate 26 is provided on one side of the threaded sleeve 251 and is located outside the support block 12, which increases the area of ​​the pressing plate 26 pressing the outer wall of the support block 12 and improves the stability of pressing and locking the rotating rod 21.

[0033] Furthermore, an anti-slip pad 261 is provided between the extrusion plate 26 and the support block 12, which increases the anti-slip properties of the extrusion plate 26 pressing against the outer wall of the support block 12.

[0034] Furthermore, a slider 27 is provided at the bottom of the clamping frame 24, and a groove 271 that matches the slider 27 is provided at the top of the support block 12, so that the clamping frame 24 and the support block 12 are slidably connected, which increases the stability of the movement of the clamping frame 24 driven by the moving block 231.

[0035] Furthermore, a silicone pad 28 is provided on the inner side of the clamping frame 24 to protect the parts and prevent the clamping frame 24 from scratching the surface of the parts when clamping.

[0036] Furthermore, a positioning rod 16 is provided at the bottom of the pressure block 15, and a through hole 161 is provided on the support block 12 to cooperate with the positioning rod 16, so as to position the pressure block 15 to move up and down and prevent the pressure block 15 from shifting when it moves up and down.

[0037] Furthermore, a limiting plate 162 is provided at the bottom of the positioning rod 16 to fit the through hole 161, thereby limiting the positioning rod 16 and preventing it from disengaging from the through hole 161 when it moves upward.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
