Description

Technical Field

[0001] This utility model relates to the field of steering knuckle processing technology, specifically a distribution-type positioning bridge plate tooling for steering knuckle processing. Background Technology

[0002] The machining process for automotive parts is quite complicated. Due to the special shape of automotive parts (such as various types of steering knuckles), grinding and drilling multiple angles and end faces pose a significant challenge to traditional CNC machine tools. If the machining end face or drilling surface is changed, not only the cutting tool but also the machining seat and fixture must be changed, which takes a long time and reduces the machining efficiency.

[0003] Currently, the machining efficiency of grinding or drilling various types of steering knuckles for automobiles is low. It requires disassembling and replacing individual parts before reprocessing, without the ability to adjust on the mounting base, or even disassembling the entire mounting base, resulting in low efficiency. For example, CN11911560B discloses a rotary fixture for machining automotive steering knuckles, including a base, a tilting mechanism, and a clamping mechanism. The tilting mechanism includes a tilting seat and a tilting drive assembly. The tilting drive assembly is mounted on the base, and the tilting seat is mounted on the tilting drive assembly. The tilting seat has a clearance groove for one end of the steering knuckle to pass through. The clamping mechanism is mounted on the tilting seat and is used to clamp the steering knuckle. This rotary fixture, through the design of the tilting and clamping mechanisms, achieves multi-faceted machining of the steering knuckle, improving machining efficiency and accuracy. This application has the effect of improving machining efficiency; however, when machining different types of steering knuckles, the entire fixture needs to be disassembled, and the position of the positioning effects or positioning parts on the fixture cannot be adjusted, resulting in low replacement efficiency.

[0004] Therefore, it is necessary to design a distribution-type positioning bridge plate tooling for steering knuckle machining to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a distribution-type positioning bridge plate tooling for steering knuckle machining, so as to solve the problem mentioned in the background art that the entire tooling needs to be disassembled when changing the machined parts, which wastes time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A distribution-type positioning bridge plate tooling for steering knuckle machining includes a bridge plate tooling body. Both ends of the bridge plate tooling body are connected to the positioner base. A positioning seat is installed on the bridge plate tooling body. Several fastening bolt holes and positioning insertion holes are distributed in a circular array on the positioning seat. The positioning insertion holes are connected to the positioning component through a clamping mechanism. The top ball on the positioning component abuts against the steering knuckle workpiece. A circular hole in the middle of the steering knuckle workpiece passes through a shaft on a pressure plate. The shaft on the pressure plate extends out of the outer end of the steering knuckle workpiece and is threadedly connected to a limiting component. The pressure plate is connected in the mounting base.

[0007] Compared with the prior art, the beneficial effects of this utility model are: by setting a clamping mechanism in multiple positioning holes, this utility model fixes the tapered part and ball head structure at the end of the positioning part, realizes the fixed connection between the positioning part and the mounting base, facilitates quick disassembly, achieves flexible adjustment, and improves the replacement efficiency of the parts.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0011] like Figures 1-6As shown, this utility model discloses a distribution-type positioning bridge plate tooling for steering knuckle processing, including a bridge plate tooling body 1. Both ends of the bridge plate tooling body 1 are connected to the positioner base 2. A positioning seat 3 is installed on the bridge plate tooling body 1. Several fastening bolt holes and positioning insertion holes 301 are distributed in a circular array on the positioning seat 3. The positioning insertion holes 301 are connected to the positioning component 8 through a clamping mechanism. The top ball 804 on the positioning component 8 abuts against the steering knuckle workpiece 7. The circular hole in the middle of the steering knuckle workpiece 7 passes through the shaft on the pressure plate 5. The shaft on the pressure plate 5 extends out of the outer end of the steering knuckle workpiece 7 and is threadedly connected to the limiting component 6. The pressure plate 5 is connected in the mounting base 4.

[0012] Multiple positioning seats 3 can be installed on the main body 1 of the bridge plate tooling to process the steering knuckle workpiece 7 synchronously. The distributed processing and independent processing space improve work efficiency and save time for changing tooling.

[0013] like Figure 5 and Figure 6 As shown, the clamping mechanism includes a washer groove 302 in the middle of the positioning insertion hole 301, and an ejection hole 304 extending through the bottom of the positioning insertion hole 301. The end of the ejection hole 304 is blocked by the inner sleeve 303. The ejection hole 304 is provided to facilitate the subsequent replacement of the inner sleeve 303. Simply remove the elastic retaining ring from the hole, and then insert a steel needle into the ejection hole 304 to assist in ejecting the inner sleeve 303. An elastic clamp 305 is connected inside the inner sleeve 303. The size of the elastic clamp 305 is adapted to the diameter of the ball head structure 802. The ball head structure 802 is fixed on the tapered member 801 on the positioning member 8. The diameter of the washer groove 302 matches the diameter of the elastic retaining ring that mates with the end of the inner sleeve 303. The inner sleeve 303 of this invention is positioned in the positioning insertion hole 301 by the elastic retaining ring. The inner sleeve 303 is open towards the opening of the positioning hole 301. In practical applications, the length of the inner sleeve 303 is half the depth of the positioning hole 301, and the diameter of the positioning hole 301 is greater than the width of the tapered part 801.

[0014] When the positioning member 8 is inserted into the positioning socket 301, the ball head structure 802 engages with the elastic clamp 305, ending the insertion action and completing the connection between the positioning member 8 and the positioning seat 3. This invention allows the inner sleeve 303 to be pre-placed into the positioning socket 301 as needed.

[0015] Multiple positioning seats 3 can be installed on the bridge plate tooling body 1. These positioning seats 3 are arranged symmetrically about the center of the bridge plate tooling body 1. The steering knuckle workpiece 7 has multiple locations requiring drilling and grinding, and these locations can abut against the top balls 804 on the positioning component 8. The positioning component 8 can match multiple positioning holes 301. The end of the positioning component 8 near the steering knuckle workpiece 7 is a truncated cone shape, with a recess at its truncated cone end. A spring is installed in this recess for the top balls 804 to extend into. The position of the positioning component 8 can be adjusted according to the position of the holes machined on the steering knuckle workpiece 7. Multiple positioning holes 301 are distributed on the positioning seat 3 for the installation and selection of the positioning component 8.

[0016] Working principle: First, the positioning component 8 is pre-installed into the positioning socket 301 at the appropriate position. After the positioning component 8 is inserted into the appropriate positioning socket 301, the ball head structure 802 on the conical component 801 gradually opens the elastic clamp 305, finally allowing the ball head structure 802 to smoothly engage with the elastic clamp 305, completing the connection between the positioning component 8 and the corresponding positioning socket 301. The steering knuckle workpiece 7 that needs to be ground or drilled is placed on the pressure plate 5, with the central hole aligned with the threaded rod of the pressure plate 5. Then, the limiting component 6 is rotated and installed onto the pressure plate 5, so that the top ball 804 can abut against one of the positions of the steering knuckle workpiece 7 that needs to be ground or drilled, thus initially fixing the steering knuckle workpiece 7. When it is necessary to disassemble the positioning component 8, the ball head structure 802 is pulled out forcefully to loosen the engagement with the elastic clamp 305, or a steel needle is inserted into the ejection hole 304 to eject the entire inner sleeve 303.

[0017] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
