Detailed Implementation

[0032] The present invention will be described in detail below with reference to specific embodiments.

[0033] This utility model provides a machining fixture for automotive front pusharms, mainly used to achieve... Figure 1 The quick-clamping and fixing mechanism shown allows for the machining of various holes or end faces, thereby improving the machining efficiency of the automotive front pusharm and ensuring the machining quality of the corresponding machined parts.

[0034] like Figure 2 As shown, its main structure includes a positioning component 1, a pressure plate component 2, and a clamping component 3;

[0035] The positioning component is used to quickly position and accurately locate the front pusharm of an automobile, ensuring that it can be fixedly supported in the correct position, facilitating continuous machining on CNC machine tools and other equipment, reducing the need for repetitive tool setting and alignment, and providing an effective support area to ensure that machining can be completed smoothly.

[0036] like Figure 2 , Figure 3 , Figure 4 As shown, the positioning component 1 includes a base plate 10 and a support block located on the base plate 10;

[0037] The base plate 10 is set horizontally, and a front push arm positioning hole 10a is provided in the bottom of the base plate 10 to match the lower bushing 9a at the lower end of the front push arm 9. A positioning groove 10b corresponding to the outer annular plate surface 9b of the lower bushing 9a is dug out in the upper section of the front push arm positioning hole 10a. An clearance hole 10c corresponding to the four front push arm fixing holes 9c at the edge of the positioning groove 10b is dug out at the edge of the annular plate surface 9b.

[0038] The support block is located behind the front push arm positioning hole 10a, and its side is provided with a positioning plane for positioning the upper side of the front push arm 9.

[0039] The pressure plate assembly 2 includes several pressure plates disposed on the left and right sides of the front push arm positioning hole 10a;

[0040] The clamping assembly 3 is located on the base plate 10 and is directly opposite the support block, and includes: cylinder mounting seat 30, dual-axis cylinder 31, connecting shaft 32, and C-shaped pressure plate 33;

[0041] The cylinder mounting base 30 is fixed on the base plate 10. The dual-shaft cylinder 31 is located on the top of the cylinder mounting base 30 and the cylinder axial support block extends out. The connecting shaft 32 is horizontally set and its two ends are fixed on the two shafts of the dual-shaft cylinder 31. The C-shaped pressure plate 33 has a connecting hole in the middle and is sleeved on the connecting shaft 31 through the connecting hole.

[0042] like Figure 5 , Figure 6 As shown, in order to improve processing efficiency and realize batch continuous processing of automotive front push arms, this embodiment adopts a multi-station structure design scheme. Specifically, the base plate 10 is provided with a plurality of front push arm positioning holes 10a evenly arranged in the left and right directions.

[0043] There are multiple support blocks, including a middle positioning block 11 with positioning planes on both the left and right sides and an end positioning block 12 with a positioning plane on only one side.

[0044] There are multiple clamping components 3, which are located between two intermediate positioning blocks 11 or between an intermediate positioning block 11 and an end positioning block 12.

[0045] The cylinder mounting base 30 has two dual-shaft cylinders on its top, which extend horizontally to the left and right sides respectively.

[0046] To ensure stable clamping and fixing of the vehicle's front pusharm, in this embodiment, the pressure plate includes L-shaped pressure plates 20 located on both sides and a strip-shaped pressure plate 21 located in the middle. The L-shaped pressure plates 20 and the strip-shaped pressure plate 21 cooperate with each other to wrap around the lower end of the vehicle's front pusharm, ensuring that it can be fixed in the front pusharm positioning hole 10a.

[0047] In particular, to improve clamping efficiency and simplify the assembly difficulty of the intermediate area pressure plate in multi-station operation, an automated clamping method can be adopted to improve the assembly method of the intermediate area pressure plate, including: a strip-shaped pressure block 40 located between adjacent front push arm positioning holes 10a and a servo cylinder 41 for pushing the strip-shaped pressure block 40 up and down; wherein the strip-shaped pressure block 40 is fixedly mounted on the cylinder shaft of the servo cylinder 41.

[0048] In actual use, the support block needs to be able to stably clamp the upper U-shaped wall area of ​​the front push arm of the car. To ensure the effectiveness of the clamping, the support block itself needs to be stably connected to the base plate. As a conventional solution, in order to simplify the processing difficulty and ensure the structural stability after assembly, in this embodiment, the support block includes a connecting part 16 connected to the base plate 10 at the bottom and a positioning part 17 located at the top of the connecting part 16.

[0049] The connecting part 16 is provided with at least three support block positioning holes, and the base plate 10 is provided with corresponding through holes. The connecting part 16 is fixed by bolt and nut groups provided in the support block positioning holes and through holes.

[0050] Specifically, to facilitate accurate positioning before processing and rapid assessment of the clamping effect, this embodiment incorporates a strip-shaped horizontal positioning part 11a for positioning the automotive front pusharm, taking advantage of the U-shaped horizontal end face structure at the upper end of the automotive front pusharm. By measuring the height and levelness of the top plane of the strip-shaped horizontal positioning part relative to the horizontal end face of the automotive front pusharm, the clamping accuracy and effectiveness can be quickly detected and analyzed, ensuring the effectiveness of the clamping.

[0051] Specifically, in some process flows, to facilitate the machining of the end face of the front axle cylinder of the automobile and the structural movement during textile processing, a positioning pin 14 is installed in the positioning hole 10a of the front push arm. This is to further improve its positioning and fixing strength.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
