Description

Technical Field

[0001] This utility model relates to the field of processing and positioning technology, and in particular to a fixing device for processing a front crossbeam bracket. Background Technology

[0002] Machining fixation restricts the workpiece's degrees of freedom of movement, ensuring that it maintains a precise position during machining. This prevents positional shifts caused by external factors such as vibration and cutting forces, thus guaranteeing machining accuracy and stability.

[0003] When processing and fixing the front crossbeam bracket, the traditional method is to use bolts. However, since the crossbeam processing requires drilling holes in the surface, metal shavings will adhere to the bolt surface, thus affecting the fixing effect. Therefore, a fixing device for processing the front crossbeam bracket is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems raised by the prior art by proposing a fixing device for processing a front crossbeam bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fixing device for processing a front crossbeam bracket includes a fixing plate, an mounting plate fixedly connected to the surface of the fixing plate, a protective sleeve slidably connected to the inner wall of the fixing plate, a protective plate fixedly connected to the surface of the protective sleeve, a front beam body placed between the fixing plate and the protective plate, and a positioning and pressing mechanism provided on the inner wall of the fixing plate.

[0006] Preferably, the positioning and pressing mechanism includes a fixed shaft fixedly connected to the inner wall of the mounting plate, a toggle lever rotatably connected to the surface of the fixed shaft, a rotating shaft fixedly connected to the inner wall of the mounting plate, a first connecting rod rotatably connected to the surface of the rotating shaft, and an anti-slip sleeve fixedly connected to the surface of the toggle lever.

[0007] Furthermore, a second link is rotatably connected to the inner wall of the first link, and the surface of the second link is rotatably connected to the surface of the actuating rod.

[0008] Preferably, a third link is rotatably connected to the inner wall of the second link, a first pressing plate is rotatably connected to the inner wall of the third link, and a pair of limiting plates are fixedly connected to the inner wall of the fixed plate, with the surfaces of the pair of limiting plates in contact with the surface of the first pressing plate.

[0009] Furthermore, a positioning plate is fixedly connected to the surface of the protective plate, and a second pressing plate is slidably connected to the inner wall of the positioning plate. The surface of the second pressing plate and the surface of the first pressing plate are fixedly connected to the same connecting plate.

[0010] Preferably, the inner wall of the protective plate is threaded with a threaded rod, one end of which is rotatably connected to the inner wall of the fixed plate, and one end of which is fixedly connected to a rotating shaft.

[0011] The beneficial effects of this utility model are as follows: The operator rotates the lever around the fixed axis, which drives the third link to descend via the second link. When the first pressing plate descends, it drives the second pressing plate to descend via the connecting plate. The first pressing plate and the positioning plate together press down on the upper surface of the front beam body to keep it fixed, which facilitates subsequent drilling operations on the front beam body. At the same time, the protective sleeve protects the threaded rod to prevent external debris from adhering to the surface of the threaded rod and affecting the movement of the protective plate. The advantage of this is that it achieves a quick and self-locking clamping effect. Attached Figure Description

[0021] In this utility model, reference is made to Figure 2 The inner wall of the second link 9 is rotatably connected to the third link 10, the inner wall of the third link 10 is rotatably connected to the first pressing plate 15, and the inner wall of the fixed plate 1 is fixedly connected to a pair of limiting plates 16, the surfaces of the pair of limiting plates 16 are in contact with the surface of the first pressing plate 15.

[0022] By setting the third link 10, the first pressing plate 15 is driven to move. The first pressing plate 15 presses the upper surface of the front beam body 4 to maintain stability.

[0023] In this utility model, reference is made to Figure 2 A positioning plate 12 is fixedly connected to the surface of the protective plate 2. A second pressing plate 11 is slidably connected to the inner wall of the positioning plate 12.
