Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a camera bracket machining fixture. Background Technology

[0002] In the manufacturing process of camera brackets, precision machining is a crucial step in ensuring product dimensional accuracy and assembly performance. Traditional machining methods typically employ general-purpose fixtures with three-jaw chucks or flat-jaw vises for clamping. However, due to the complex, irregular structure of camera brackets, especially those with concave sections, bevels, and irregular contours, general-purpose fixtures struggle to achieve stable and reliable positioning and clamping. Existing positioning methods often suffer from the following drawbacks: first, the lack of dedicated positioning surfaces for the specific structure of camera brackets leads to easy workpiece displacement; second, the clamping force is applied in a single direction, making it difficult to simultaneously address the fixation requirements of the sides and bottom; and third, vibration and displacement caused by cutting forces during machining affect machining accuracy. Furthermore, the adjustment mechanisms of conventional fixtures are cumbersome to operate and cannot quickly adapt to the machining requirements of different camera bracket models. These shortcomings not only result in low machining efficiency but can also lead to workpiece scrap due to positioning errors. Therefore, there is an urgent need to develop a dedicated fixture capable of multi-directional positioning, stable clamping, and convenient operation to meet the technical requirements of high-precision machining of camera brackets.

[0040] The following is for reference. Figures 1-4 A camera bracket machining fixture is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0041] like Figure 1 As shown, the camera bracket 130 machining fixture mainly consists of a base plate 100, a positioning block 120, a clamping mechanism, and a support block 200. The base plate 100 has a machining opening 110 that matches the contour of the camera bracket 130. This design provides ample operating space for machining and facilitates observation of the workpiece and chip removal during processing. A positioning block 120 is located on one side of the machining opening 110. Its side near the machining opening 110 is precision-machined to form a plane 140 and a slope 150 at a certain angle. The plane 140 contacts the main body of the camera bracket 130 for primary positioning, while the slope 150 matches the tilting characteristics of the workpiece for auxiliary positioning. Specifically, as... Figure 4 As shown, a protrusion 170 is also provided on the positioning plane 140, which precisely matches the recess 160 of the camera bracket 130. The concave-convex interlocking structure further restricts the workpiece's degree of freedom and ensures positioning accuracy. The positioning block 120 is fixedly connected to the base plate 100 through the first mounting hole 240 and the first bolt (not shown in the figure). The bolt installation method facilitates the adjustment of the position of the positioning block 120 according to the workpiece size.

[0042] Specifically, a clamping mechanism is provided on the other side of the machining opening 110. This mechanism includes a rectangular clamping block 180 and a clamping cylinder 190 that drives the clamping block 180. The clamping cylinder 190 is securely mounted on the base plate 100 through a second mounting hole 250 and a second bolt (not shown in the figure). Its output end is connected to the clamping block 180 through three parallel output rods 260. This multi-rod connection design ensures that the clamping force is evenly distributed on the workpiece surface. When the cylinder is activated, the clamping block 180 pushes the camera bracket 130 as a whole towards the positioning block 120, so that the workpiece is simultaneously in close contact with the plane 140 and the inclined surface 150 of the positioning block 120. The direction of the clamping force is precisely calculated to ensure sufficient clamping strength without causing workpiece deformation. On the other side between the positioning block 120 and the clamping mechanism, a support block 200 is provided. A support step 210 is machined on its top to support the overhanging end of the camera bracket 130, achieving three-point support positioning. The support block 200 is fixed to the base plate 100 through the third bolt hole 270 and the third bolt (not shown in the figure) for easy height adjustment. The support block 200 has two parallel threaded holes 220 on its side, and an adjustable positioning bolt 230 is installed in each threaded hole 220. By tightening the bolt, its end contacts the bottom side of the camera bracket 130 to form a lateral limit.

[0043] To further enhance the adaptability of the fixture, such as Figure 3 As shown, the rotary base 280 is provided with a mounting groove 290 for mounting to the side of the base plate 100. The rotary base 280 adopts a high-strength bearing structure, enabling the entire fixture to rotate around its axis, facilitating multi-angle machining. Figure 2 As shown, the support plate 300 effectively distributes the force during rotation, preventing deformation of the base plate 100. All mounting contact surfaces are ground to ensure a 140-degree flatness and perpendicularity of the mating surfaces. All bolt connections are designed to prevent loosening, ensuring a stable connection even under processing vibration.

[0044] The working process of this fixture is as follows: First, loosen the clamping cylinder 190 and the positioning bolt 230, and place the camera bracket 130 on the stepped surface of the support block 200; adjust the position of the workpiece so that its concave part 160 engages with the protrusion 170 of the positioning block 120, while ensuring that the workpiece body is in complete contact with the positioning plane 140 and the inclined plane 150; activate the clamping cylinder 190 to press the workpiece body with the pressure block 180; finally, tighten the positioning bolts 230 on both sides to complete the lateral fixation. The fixture angle can be rotated as needed during processing. Throughout the process, the workpiece is simultaneously positioned by the plane 140, the inclined plane 150, and the protrusion 170 of the positioning block 120, the clamping mechanism applies pressure evenly at multiple points, and the support block 200 and the positioning bolt 230 provide auxiliary limiting, forming a stable clamping solution in all directions.

[0045] The overall benefits of this fixture are reflected in the following aspects: Through the synergistic effect of the composite positioning structure and multi-directional clamping device, the positioning problem during the machining of the irregularly shaped camera bracket 130 is completely solved. Its unique three-level positioning system (plane 140-sloping surface 150-protrusion 170) ensures the spatial positioning accuracy of the workpiece; the three-output rod 260 clamping mechanism achieves deformation-free clamping; and the adjustable support structure and double positioning bolt 230 design effectively suppress machining vibration. The addition of a rotation function expands the machining range, and the modular installation method improves the fixture's adaptability. The overall structure ensures rigidity while also considering ease of operation, significantly improving the machining accuracy and production efficiency of the camera bracket 130.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
