Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a milling fixture for a pull rod fork. Background Art

[0002] As a key component of automotive parts, the tie rod fork plays a vital role in the production of the whole vehicle. This part not only needs to meet the high standards of structural strength and safety, but also must undergo high-precision processing to meet the stringent requirements of modern automobiles for performance and reliability. The manufacturing process of the tie rod fork is a complex and delicate process, which usually includes multiple steps. Among them, casting the blank is the starting stage, which provides a solid foundation for subsequent machining. After the blank casting is completed, the machining of the working surface becomes a key step to ensure the dimensional accuracy, shape and surface quality of the part. In the machining process, the M12 internal threaded hole and the end face with a diameter of 20 are usually the earliest completed machining surfaces. The completion of these machining surfaces marks the initial forming of the tie rod fork and lays the foundation for subsequent machining steps. However, for the tie rod fork, the milling of the 12.5 and 28 side surfaces is a crucial part of the subsequent processing. In order to ensure the smooth progress of the milling process, a special tie rod fork milling fixture is required. This fixture can stably fix the tie rod fork so that it will not move or deform during the milling process, thereby ensuring the machining accuracy and quality.

[0003] In current manufacturing technology, the milling fixture processing of the tie rod fork generally adopts the traditional bench marking method, followed by clamping and alignment processing on the machine tool with the help of a three-jaw chuck. However, this traditional method has significant limitations and shortcomings, which seriously restricts the improvement of processing efficiency and precision.

[0004] First, the inherent subjectivity and uncertainty of the marking process make it difficult to stably control the marking accuracy. Different operators have different skill levels and experience, so it is difficult to ensure the consistency and accuracy of marking, which directly affects the positioning accuracy and overall quality of subsequent processing.

[0005] Secondly, as a clamping tool, the three-jaw chuck is difficult to ensure uniformity and stability of the clamping force when clamping the tie rod fork. During the processing, the cutting force may cause the tie rod fork to move slightly or deform, which seriously affects the processing accuracy and product quality.

[0006] Finally, the alignment process is cumbersome and time-consuming. Before processing, the pull rod fork must be adjusted and positioned multiple times to ensure its concentricity with the machine tool spindle, which not only increases the labor intensity of the operator, but also reduces the overall production efficiency and increases the manufacturing cost.

[0007] Based on the above defects, a milling fixture for a pull rod fork is proposed to solve the above problems. Utility Model Content

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Combination Figure 1-Figure 5 As shown, a milling fixture for a pull rod fork of the utility model comprises a pull rod fork body 1, wherein one end of the pull rod fork body 1 is further provided with a threaded hole 2.

[0042] A clamp body base 3, one end of which is placed on the table, and the pull rod fork body 1 can be placed on the other side surface of the clamp body base 3;

[0043] The threaded pins 4 are fixedly mounted on the side surface of the clamp body base 3 away from the table surface, and the number of the threaded pins 4 is two, wherein the pull rod fork body 1 is connected to the outer side of the threaded pins 4 to connect the pull rod fork body 1 and the clamp body base 3 to each other;

[0044] The anti-rotation limiter 5 is disposed on the clamp body base 3 and contacts the surface of the pull rod fork body 1. The limiter 5 is used to abut against the surface of the pull rod fork body 1 to prevent the pull rod fork body 1 and the clamp body base 3 from relative axial rotation.

[0045] The pressure plate 6 is placed at the opening of the pull rod fork body 1, and locking bolts 7 which are interconnected with the clamp base 3 are provided at both ends. The opening of the pull rod fork body 1 can be limited and fixed by the pressure plate 6 and the locking bolts 7 to avoid displacement during milling.

[0046] First, one end of the tie rod fork body 1 has a threaded hole 2, which is the key part for connecting with the clamp. One end of the clamp base 3 is placed on the processing table to provide stable support for the clamp. Next, the threaded pin 4 is fixedly installed on the side surface of the clamp base 3 away from the table as the main connecting component. The two threaded pins 4 ensure that the tie rod fork body 1 can be firmly connected to the clamp base 3. Through the cooperation between the threaded pins 4 and the threaded holes 2 on the tie rod fork body 1, the tie rod fork body 1 is tightly fixed on the clamp base 3 to prevent horizontal displacement during the processing. However, the fixation of the threaded pins 4 alone is not enough to ensure the stability of the tie rod fork body 1 during the processing. Therefore, the anti-rotation limiter 5 is arranged on the clamp base 3 and contacts the surface of the tie rod fork body 1. The function of this anti-rotation limiter 5 is to prevent relative axial rotation between the tie rod fork body 1 and the clamp base 3. Rotation, during the processing, even if affected by the cutting force, the anti-rotation limit member 5 can ensure that the pull rod fork body 1 maintains a stable position. In addition, the pressure plate member 6 is placed at the opening of the pull rod fork body 1, which is used to limit and fix the opening part of the pull rod fork. Both ends of the pressure plate member 6 are provided with locking bolts 7 which are interconnected with the clamp base 3. By adjusting the locking bolts 7, the degree of clamping of the opening part of the pull rod fork body 1 by the pressure plate member 6 can be adjusted. This design ensures that the pull rod fork will not be deformed or displaced at the opening due to cutting force or other external factors during the processing. In summary, the milling fixture of the pull rod fork described is fixed by the fixed connection of the threaded pin 4, the anti-rotation design of the anti-rotation limit member 5 and the fixing of the pressure plate member 6 and the opening of the locking bolt 7, so as to achieve all-round and stable fixation of the pull rod fork body 1 during the processing, thereby solving the problems of low processing accuracy and poor stability mentioned in the background technology.

[0047] In a preferred embodiment, the present invention can be further configured as follows: Figure 1-Figure 5As shown; the outer side of the threaded pin 4 is provided with an external thread matched with the threaded hole 2, and the pull rod fork body 1 is connected to the outer side of the threaded pin 4 through the threaded hole 2 and the external thread. The threaded pin 4 serves as a connecting component between the clamp and the pull rod fork body 1, and its outer side is designed with an external thread. These external threads are matched with the internal threads in the threaded hole 2 set at one end of the pull rod fork body 1. In fact, the "internal thread" here refers to the threaded feature of the threaded hole 2 on the pull rod fork body 1 itself, which is functionally equivalent to the internal thread. When the pull rod fork body 1 needs to be fixed on the clamp body, first place the clamp body base 3 on the processing table, and then place the pull rod fork body 1 on the other side surface of the clamp body base 3. Next, align the threaded pin 4 with the threaded hole 2 on the pull rod fork body 1, and rotate the threaded pin 4 so that its external thread and the internal thread of the threaded hole 2 engage with each other. Due to the precise design of parameters such as pitch and helix angle, the connection between the threaded pin 4 and the tie rod fork body 1 will be very tight and stable. With the further rotation of the threaded pin 4, the contact area between its external thread and the internal thread of the tie rod fork body 1 gradually increases, and the friction force also increases accordingly. This design not only ensures the stable fixation of the tie rod fork body 1 in the horizontal direction, but also prevents it from axial displacement or rotation due to cutting force or other external forces to a certain extent. In addition, by adjusting the screw-in depth of the threaded pin 4, the clamping force of the tie rod fork body 1 can also be precisely controlled. This design enables the clamp to adapt to tie rod fork bodies 1 of different specifications and sizes, thereby improving the versatility and flexibility of the clamp, and achieving stable and precise fixation of the tie rod fork body 1 through threaded connection, effectively solving the problems of unstable fixture fixation and low machining accuracy mentioned in the background technology.

[0048] In a preferred embodiment, the present invention can be further configured as follows: Figure 1-Figure 5As shown; a tool setting block 8 is connected to the side surface of the clamp base 3 away from the table surface through a fixing bolt, wherein the position of the tool setting block 8 is aligned with the opening position of the draw rod fork body 1. In the milling process of the draw rod fork, positioning accuracy and processing accuracy are crucial. In order to ensure that the milling tool can accurately perform processing according to the preset path, a precise reference point or reference surface is required to guide the movement of the tool. This is the key role played by the tool setting block 8. The tool setting block 8 is firmly connected to the side surface of the clamp base 3 away from the table surface through a fixing bolt, and its position is precisely designed to ensure that it is aligned with the opening position of the draw rod fork body 1. This means that when the draw rod fork body 1 is fixed on the clamp, its opening portion will directly face the tool setting block 8. Before the processing starts, the operator will use the milling tool to perform the tool setting operation. During this process, the tool will first align with the alignment The tool block 8 contacts the fork body 1 and determines its initial position and processing path through the guidance of the tool block 8. Since the position of the tool block 8 is precisely set and aligned with the opening position of the draw rod fork body 1, the tool can be accurately positioned to the position that needs to be processed. Next, when the processing starts, the milling tool will perform processing according to the preset path and parameters. Since there is the tool block 8 as a precise reference point, the tool can always maintain the correct processing position and direction, thereby ensuring the processing precision and accuracy. In addition, the use of the tool block 8 also improves the processing efficiency. Through a one-time tool setting operation, it can ensure that the position of the tool remains unchanged during the entire processing process, reducing the time waste and error accumulation caused by multiple tool settings. Through precise position setting and fixed connection, a reliable reference point is provided for the milling tool, thereby ensuring the high precision and accuracy of the draw rod fork processing.

[0049] In a preferred embodiment, the present invention can be further configured as follows: Figure 1-Figure 5 As shown; the anti-rotation limiter 5 includes:

[0050] A fixing seat 51, which is connected to the surface of the clamp body base 3 away from the table surface by connecting bolts, and the number and distribution position of the fixing seat 51 are adapted to the threaded pin 4;

[0051] The support rod 52 is arranged on the surface of the fixing seat 51, and a limit pin is arranged on the outer side of the support rod 52 to prevent the support rod 52 from being separated from the surface of the fixing seat 51;

[0052] The abutment seat 53 is fixedly mounted on one end of the support rod 52 and in contact with the surface of the pull rod fork body 1; and

[0053] The elastic member 54 is sleeved on the outer side of the support rod 52, one side surface of which is in contact with the abutment seat 53, and the other side surface is in contact with the fixed seat 51, wherein the abutment seat 53 is pressed against the surface of the pull rod fork body 1 under the elastic driving of the elastic member 54, and the anti-rotation limit member 5 is composed of the fixed seat 51, the support rod 52, the abutment seat 53 and the elastic member 54. The fixed seat 51 is firmly connected to the side surface of the clamp body base 3 away from the table surface by connecting bolts, and the number and distribution position of the fixed seat 51 are adapted to the threaded pin 4 to ensure that the anti-rotation limit member 5 can be evenly The support rod 52 is evenly distributed around the pull rod fork body 1 to provide stable support and limiting effects. The support rod 52 is set on the surface of the fixed seat 51 and serves as a connecting component between the abutment seat 53 and the fixed seat 51. In order to prevent the support rod 52 from detaching from the surface of the fixed seat 51 during processing, a limiting pin is also provided on its outer side. This design ensures the stability and reliability of the anti-rotation limiter 5 during use. The abutment seat 53 is fixedly installed on one side end of the support rod 52, which is in direct contact with the surface of the pull rod fork body 1. During processing, The abutment seat 53 will fit tightly on the surface of the rod fork body 1 to form a stable support point. The elastic member 54 is sleeved on the outer side of the support rod 52, and its one side surface is in contact with the abutment seat 53, and the other side surface is in contact with the fixed seat 51. Driven by the elasticity of the elastic member 54, the abutment seat 53 will be tightly pressed against the surface of the rod fork body 1. This design enables the anti-rotation limiter 5 to adapt to rod fork bodies 1 of different sizes and always maintain a stable contact force during the processing. When the rod fork body 1 is subjected to cutting force or other external forces At the same time, due to the elastic effect of the elastic member 54, the abutment seat 53 in the anti-rotation limit member 5 will be closely fitted with the surface of the pull rod fork body 1, thereby preventing it from axial rotation. At the same time, due to the elastic effect of the elastic member 54, the abutment seat 53 can also absorb vibration and impact to a certain extent, thereby protecting the pull rod fork body 1 from damage. In summary, the anti-rotation limit member 5 effectively solves the rotation problem that may occur in the pull rod fork during the processing through the synergistic effect of the fixed seat 51, the support rod 52, the abutment seat 53 and the elastic member 54, thereby improving the processing accuracy and product quality.

[0054] In a preferred embodiment, the present invention can be further configured as follows: Figure 1-Figure 5As shown; the support rod 52 and the abutment seat 53 are combined into a T-shaped arrangement, wherein the abutment seat 53 has two protrusions fixedly installed on the surface of one side close to the pull rod fork body 1, and the two protrusions are in contact with the surface of the pull rod fork body 1. The support rod 52 and the abutment seat 53 are combined into a T-shaped structure. This design makes the anti-rotation limiter 5 more structurally stable and can better withstand the cutting force and other external forces from the processing process. At the same time, the T-shaped structure also increases the contact area between the abutment seat 53 and the pull rod fork body 1, thereby improving the stability. Two protrusions are fixedly installed on the surface of one side of the abutment seat 53 close to the pull rod fork body 1. The functions of these two protrusions are very critical. They are in direct contact with the surface of the pull rod fork body 1 to form multiple contact points. This multi-point contact design can more evenly distribute the clamping force and prevent the pull rod fork body 1 from being rotated. If twisting or rotation occurs during the processing, when the rod fork body 1 is placed on the clamp base 3, the abutment 53 of the anti-rotation limit member 5 will fit tightly against the surface of the rod fork body 1. At this time, the two protrusions will respectively press on the corresponding positions of the rod fork body 1 to form a stable support and limiting structure. During the processing, even if the rod fork body 1 is subjected to cutting force or other external forces, due to the T-shaped structure of the anti-rotation limit member 5 and the presence of two protrusions, these forces will be evenly dispersed to multiple contact points, thereby maintaining the stability and processing accuracy of the rod fork body 1. In addition, this design also has a certain degree of fault tolerance. Even if the size or shape of the rod fork body 1 changes slightly, due to the multi-point contact and the support of the T-shaped structure, the anti-rotation limit member 5 can still maintain a stable clamping effect, thereby ensuring the smooth progress of the processing process.

[0055] In a preferred embodiment, the present invention can be further configured as follows: Figure 1-Figure 5 As shown; the pressure plate member 6 comprises:

[0056] The pressure plate seat 61 is placed inside the opening position of the pull rod fork body 1, and two holes are processed on its surface;

[0057] The V-shaped block 62 is disposed in the hole of the pressure plate seat 61 and can rotate relative to the pressure plate seat 61. The number and distribution position of the V-shaped block 62 are adapted to the hole, wherein the V-shaped block 62 can abut against the opening of the pull rod fork body 1; and

[0058] There are two C-shaped seats 63, which are fixedly installed on the two side ends of the pressure plate seat 61, and the locking bolts 7 are placed on the inner side of the C-shaped seat 63. The pressure plate member 6 is mainly composed of the pressure plate seat 61, the V-shaped block 62 and the C-shaped seat 63, aiming to provide a more stable fixing effect and ensure the stability of the pull rod fork body 1 during the processing. The pressure plate seat 61 is placed on the inner side of the opening position of the pull rod fork body 1. The surface of the pressure plate seat 61 is processed with two holes, and these two holes are used to install the V-shaped blocks 62. The number and distribution position of the V-shaped blocks 62 are adapted to the holes on the pressure plate seat 61 to ensure that a V-shaped block 62 can be installed in each hole. The V-shaped block 62 is designed to be able to undergo relative rotational displacement with the pressure plate seat 61. This design allows the V-shaped block 62 to adaptively adjust its angle when it is under pressure to ensure that it fits more closely with the opening of the pull rod fork body 1. When the V-shaped block When 62 abuts against the opening of the pull rod fork body 1, they will form a stable supporting structure to prevent the pull rod fork body 1 from being displaced or rotated during the processing. In order to ensure the stability and fixing effect of the pressure plate 6, a C-shaped seat 63 is also designed. There are two C-shaped seats 63, which are fixedly mounted on the two side ends of the pressure plate seat 61 respectively. A locking bolt 7 is placed on the inner side of each C-shaped seat 63. By rotating the locking bolt 7, it can be tightly fitted with the pressure plate seat 61 and the V-block 62, so that the entire pressure plate member 6 is firmly fixed on the pull rod fork body 1. During the processing, even if the pull rod fork body 1 is subjected to cutting force or other external forces, due to the stable structure of the pressure plate member 6 and the tightening effect of the locking bolt 7, the pull rod fork body 1 can remain stable and motionless, which can not only improve the processing accuracy, but also extend the service life of the tool and reduce production costs.

[0059] In a preferred embodiment, the present invention can be further configured as follows: Figure 1-Figure 5As shown; connecting screw holes 9 that are compatible with locking bolts 7 are processed on the surface of the clamp body base 3, and the ends of the locking bolts 7 are threadedly connected to the inner sides of the connecting screw holes 9, wherein the number and distribution positions of the connecting screw holes 9 correspond one-to-one to the locking bolts 7, and an arc washer 10 is also provided between the locking bolts 7 and the C-shaped seat 63, and the arc washer 10 is sleeved on the outer side of the locking bolt 7, and connecting screw holes 9 that are compatible with the locking bolts 7 are processed on the surface of the clamp body base 3. The number and distribution positions of these connecting screw holes 9 correspond one-to-one to the locking bolts 7, ensuring that each locking bolt 7 can be accurately screwed into the corresponding connecting screw hole 9, and the C-shaped seats 63 in the pressure plate member 6 are located on both sides of the pressure plate seat 61, and are used to fix the pressure plate member 6 on the clamp body base 3. When the pressure plate member 6 is placed in the open position of the pull rod fork body 1, the locking bolt 7 passes through the C-shaped seat 63 and is screwed into the clamp In the connecting screw hole 9 on the specific base 3, an arc washer 10 is also arranged between the locking bolt 7 and the C-shaped seat 63. This arc washer 10 is sleeved on the outer side of the locking bolt 7. It has two main functions: one is to provide additional support and stability to enhance the connection strength between the locking bolt 7 and the C-shaped seat 63; the second is to enable the locking bolt 7 to be evenly stressed during the tightening process through its arc shape to avoid stress concentration, thereby extending the service life of the locking bolt 7. As the locking bolt 7 is gradually tightened, the pressure plate 6 is firmly fixed on the clamping base 3, and the opening of the pull rod fork body 1 is also tightly clamped by the V-block 62. This design not only ensures the stability of the pull rod fork body 1 during the processing process, but also can resist the impact of cutting force or other external forces to a certain extent, and prevent the pull rod fork body 1 from displacement or deformation.

[0060] The milling fixture of the pull rod fork is used to firmly fix the pull rod fork body 1 during the processing to prevent it from displacement or rotation during processing, so as to ensure the processing accuracy and product quality.

[0061] One end of the tie rod fork body 1 is threadedly connected to the threaded pin 4 on the clamp body base 3 through its built-in threaded hole 2. This connection method ensures a firm connection between the tie rod fork body 1 and the clamp body base 3, and allows the tie rod fork body 1 to be fine-tuned when necessary. In order to ensure that the tie rod fork body 1 does not rotate during the processing, an anti-rotation limiter 5 is provided. The anti-rotation limiter 5 consists of a fixed seat 51, a support rod 52, an abutment seat 53 and an elastic member 54. The fixed seat 51 is fixed to the clamp body base 3 by connecting bolts, and the support rod 52 passes through the fixed seat 51 and is prevented from detaching by a limit pin. The abutment seat 53 is installed at one end of the support rod 52 and abuts on the surface of the tie rod fork body 1 through the elastic force of the elastic member 54. This design ensures that the abutment seat 53 always maintains close contact with the tie rod fork body 1 to prevent it from rotating. In order to further enhance the fixing effect of the tie rod fork body 1, especially for its opening, a pressure plate member 6 is designed. The pressure plate member 6 includes a pressure plate seat 61, a V-shaped block 62 and a C-shaped seat 63. The pressure plate seat 61 is placed on the inner side of the opening position of the pull rod fork body 1, and the V-shaped block 62 is installed in the hole of the pressure plate seat 61, and can be rotated relative to the pressure plate seat 61 to adapt to pull rod fork bodies 1 of different shapes. The C-shaped seat 63 is fixed on both sides of the pressure plate seat 61, and is connected to the connecting screw holes 9 on the clamp body base 3 through the locking bolts 7. An arc washer 10 is also provided between the locking bolts 7 and the C-shaped seat 63 to provide additional support and stability. In addition, a tool setting block 8 is also connected to the clamp body base 3, and its position is aligned with the opening position of the pull rod fork body 1, so as to facilitate precise tool setting during the processing.
