Description

Technical Field

[0001] This application relates to the field of finishing tooling, and in particular to a tooling for finishing the burrs on a steering column cover. Background Technology

[0002] A steering column cover is a housing structure used to protect the steering column. It is usually installed on the outside of the steering column and forms a shell barrier to prevent external contaminants such as dust and water from entering the steering column, thus effectively protecting it.

[0003] In the prior art, referring to Figure 1-3 The steering column cover 5 is typically a shell structure with a cavity 51, and the shell is an open structure. Multiple connecting posts 52 are formed within the cavity 51. Each connecting post 52 has a mounting hole 53, one end of which extends into the interior of the connecting post 52, and the other end is located on the surface of the steering column cover 5. Normally, the connecting posts 52 and the shell are integrally injection molded. After molding, injection flash may sometimes exist at the edge of the opening of the steering column cover 5. To ensure that the steering column cover 5 can be properly installed on the outside of the steering column, flash removal is required. When removing flash from the steering column cover 5, tooling fixtures are usually used to secure the steering column cover 5.

[0004] However, in existing technologies, tooling fixtures typically require multiple jaws to hold the steering column cover in place. These jaws can interfere with subsequent flash trimming operations. Therefore, after trimming a portion of the flash, the jaws need to be released to clamp other parts of the steering column cover, thus completing the trimming of all flash. It is evident that trimming the flash of the steering column cover sometimes requires multiple clamping operations, resulting in a significant workload. Summary of the Invention

[0005] In order to reduce the amount of tooling clamping work during the trimming of the burrs on the steering column cover, this application provides a tooling for trimming the burrs on the steering column cover.

[0006] The tooling for trimming the burrs on a steering column cover provided in this application adopts the following technical solution:

[0007] A tooling for trimming the burrs on a steering column housing includes:

[0008] A locking assembly, comprising a locking element;

[0009] The support assembly is provided in multiple parts, the support assembly includes a support column and a support base, the support column is used to cooperate with the mounting hole of the steering column cover to be repaired to support and limit the steering column cover, and the support base is used to cooperate with the locking member.

[0010] A clamping assembly includes a clamping member and a fixing member, the clamping member being used to press the steering column housing towards the support assembly, the fixing member being connected to the clamping member, and the fixing member being configured to cooperate with the locking member;

[0011] The locking member is configured to simultaneously lock or unlock the support base and the fixing member under the same control state.

[0012] When the locking member is in the locked state, the locking member applies an adsorption force to the support base and the fixing member respectively, so that a first locking force is formed between the support assembly and the locking member, and the steering column housing is pressed and fixed by the clamping member, thereby restricting the movement of the support assembly relative to the locking member;

[0013] When the locking member is in the unlocked state, the attraction between the locking member and the support base and the fixing member is released, and the support assembly forms a magnetic attraction with the locking member through the auxiliary member disposed thereon, so as to form a second locking force between the support assembly and the locking member. The second locking force is less than the first locking force, and the support assembly maintains a stable relative position when no external force is applied, and can move relative to the locking member when an external force is applied.

[0014] Furthermore, the support column includes a tip, which is tapered and is used to mate with the mounting hole of the steering column housing to be repaired.

[0015] Furthermore, the locking element is an electromagnet, a metal layer is embedded in the bottom of the support base, and the fixing element is made of ferromagnetic material, so that the locking element can attract the support base and the fixing element respectively when energized.

[0016] Furthermore, the auxiliary component is disposed within the support base and connected to the support column. The auxiliary component is a magnetic component and is capable of moving within the support base in a direction close to or away from the locking component.

[0017] Furthermore, the auxiliary component is a magnetic component, and when the locking component is energized, a magnetic field distribution in the same direction as the auxiliary component is formed at the auxiliary component, so that the two generate a repulsive force, thereby driving the support column to move toward the steering column housing; when the locking component is de-energized, the auxiliary component and the locking component are attracted to each other through magnetic attraction.

[0018] Furthermore, the clamping component includes a vertical rod, a connecting rod, and a clamping rod. The two ends of the connecting rod are respectively connected to the vertical rod and the clamping rod. The vertical rod is disposed on the outside of the steering column housing, and the clamping rod extends into the cavity of the steering column housing to form a clamping structure that spans the edge of the housing.

[0019] Furthermore, the end of the clamping rod is configured as a spherical structure, which contacts the steering column housing to form a surface contact in the contact area.

[0020] Furthermore, the locking assembly also includes a base, and the locking element is fixedly disposed on the base.

[0021] Furthermore, the support base is made of non-metallic material.

[0022] Furthermore, the support column is axially adjustable on the support base to accommodate steering column housings of different sizes or different step heights, and its position is locked by the locking assembly after adjustment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When it is necessary to adjust the trimming fixture to ensure that all edges of the steering column cover to be trimmed can be trimmed, the steering column cover can be re-clamped simply by releasing the lock between the clamping parts and the locking assembly, moving the position of the clamping parts, and then re-locking them. The operation is relatively convenient and quick, eliminating the need for multiple clamping operations and greatly reducing the workload of the operators.

[0025] 2. Multiple support columns can adapt to mounting holes in various height areas;

[0026] 3. When the clamping component clamps the steering column housing, it forms an inverted "U" shape. The clamping rod extends into the cavity of the steering column housing. The clamping rod and the upright are located on both sides of the edge of the steering column housing, respectively. The clamping component as a whole only interferes with one side edge of the steering column housing, thereby reducing the number of times the clamping component needs to be re-fixed later.

[0037] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0039] Reference Figure 4 This application discloses an embodiment of a tooling for trimming the burrs on a steering column cover, comprising a locking assembly 1, a support assembly 2, and a clamping assembly 3. The locking assembly 1 is used to lock the positions of the support assembly 2 and the clamping assembly 3. The support assembly 2 supports the steering column cover 5 to be trimmed, and the clamping assembly 3 is used to clamp the steering column cover 5 towards the support assembly 2. The structure of the steering column cover 5 is as described above. Figures 1-3 .

[0040] Specifically, refer to Figures 4-6The locking assembly 1 includes a locking element 11. Multiple support assemblies 2 are provided, connected to the locking element 11. Each support assembly 2 includes a support column 21, which matches the mounting hole 53 of the steering column housing 5 to be repaired, providing support and limiting for the steering column housing 5. The clamping assembly 3 includes a clamping element 31, which, along with the support assemblies 2, is located on the upper and lower sides of the steering column housing 5 to be repaired. The clamping element 31 is used to clamp the steering column housing 5 towards the support assembly 2.

[0041] When the locking member 11 locks the clamping member 31, a first locking force exists between the locking member 11 and the support assembly 2. Under the action of the first locking force, the relative movement between the support assembly 2 and the locking member 11 is restricted. When the locking member 11 releases its lock on the clamping member 31, a second locking force exists between the locking member 11 and the support assembly 2, and the second locking force is less than the first locking force. Under the action of the second locking force: when there is no external force moving the support assembly 2, the relative position of the locking member 11 and the support assembly 2 remains locked; when there is an external force moving the support assembly 2, the support assembly 2 can move relative to the locking member 11.

[0042] It should be noted that the number of support components 2 can be 2, 3, 4, or even more, and is not limited in this embodiment. The end of the support column 21 extends into the mounting hole 53 on the steering column housing 5. The diameter of the support column 21 is larger than the diameter of the mounting hole 53, so the support column 21 cannot pass through the mounting hole 53. Therefore, when the steering column housing 5 is placed on the support column 21, the support column 21 can provide support for the steering column housing 5. After the locking member 11 locks the support component 2 with the first locking force, the position of the support column 21 is locked. By setting multiple support columns 21, the movement of the steering column housing 5 on the plane can be restricted. However, the limiting effect of multiple support columns 21 alone is not enough to restrict the movement of the steering column housing 5 along the axial direction of the support column 21. After the locking member 11 locks the clamping member 31, the movement of the steering column housing 5 along the axial direction of the support column 21 can be restricted under the action of the clamping member 31, thereby fully restricting the movement of the steering column housing 5.

[0043] As described above, when the worker needs to adjust the steering column housing 5, the support assembly 2 and the locking member 11 are engaged, and a second locking force exists between them. At this time, by moving the support assembly 2 with external force, the positions of the multiple support columns 21 are adjusted so that each support column 21 can engage with the multiple mounting holes 53 on the steering column housing 5. The multiple support columns 21 are inserted into the mounting holes 53 on the steering column housing 5, thus providing support for the steering column housing 5. At this time, a second locking force is generated between the support assembly 2 and the locking member 11, and under the action of this second locking force, the relative positions of the locking member 11 and the support columns 21 are maintained. Then, the clamping member 31 is used to clamp the steering column cover 5, causing the locking assembly 1 to lock the position of the clamping member 31. At this time, a first locking force is generated between the support assembly 2 and the locking member 11. Under the action of the first locking force, the relative movement between the support assembly 2 and the locking member 11 is restricted, and the movement of the steering column cover 5 is restricted, thus completing the clamping of the steering column cover 5. At this time, the operator can process the burrs on the edge of the steering column cover 5.

[0044] When the clamping assembly 3 interferes with the edge of the steering column cover 5, preventing the operator from continuing to process the burrs on the edge of the steering column cover 5, it is necessary to release the locking assembly 1 from locking the clamping member 31. After the locking member 31 and the locking assembly 1 are released, under the action of the second locking force, the locking assembly 1 and the support assembly 2 can still maintain their relative positions. Without the use of external force, the support assembly 2 will not move, but the clamping member 31 can be moved. After moving the clamping member 31 to the position where the burrs on the steering column cover 5 have been processed, the locking assembly 1 can be re-locked to complete the re-clamping of the steering column cover 5. Therefore, when it is necessary to adjust the trimming fixture to ensure that all the edges of the steering column cover 5 to be trimmed can be trimmed, the re-clamping of the steering column cover 5 can be completed simply by releasing the lock between the clamping member 31 and the locking assembly 1, moving the position of the clamping member 31 and re-locking it. The operation is relatively convenient and quick, eliminating the need for multiple clamping operations and greatly reducing the clamping workload for staff.

[0045] In addition to the above, in this embodiment, the locking of the support component 2 and the locking of the clamping component 3 are both accomplished by the same locking component 1, which greatly simplifies the tooling structure and makes the tooling structure for trimming the burrs of the steering column housing 5 more concise and compact.

[0046] When using this trimming fixture to limit the position of steering column cover 5 to be trimmed, it is common to trim a batch of steering column cover 5 of the same type, with identical mounting holes 53 on the steering column cover 5. In this case, the clamping advantage of this trimming fixture is even more obvious. After the worker completes the initial locking of the support component 2, there is no need to move the support component 2 during subsequent clamping. Under the action of the second locking force, the position between the support component 2 and the locking member 11 can be maintained. It is only necessary to place the new steering column cover 5 to be trimmed on the support component 2, and then use the locking component 1 to lock the clamping member 31, so that the clamping member 31 presses the steering column cover 5 tightly, which greatly reduces the repetitive workload of clamping during the trimming of the steering column cover 5 and improves the efficiency of batch trimming of steering column cover 5.

[0047] For locking component 1, in some embodiments, refer to Figure 4-6 The locking assembly 1 may also include a base 12, with the locking element 11 fixedly connected to the base 12. The operator can connect the entire locking assembly 1 to the workbench via the base 12.

[0048] Furthermore, refer to Figure 4-6 The support column 21 includes a tapered tip that mates with the mounting hole 53 of the steering column housing 5 to be fitted. This design ensures that, firstly, the tapered shape provides self-centering, allowing the support column 21 to be well-coaxial with the mounting hole 53. Secondly, the support column 21 can accommodate mounting holes 53 of different sizes, increasing the applicability of this fitting.

[0049] Furthermore, refer to Figure 4-6 The support assembly 2 also includes a support base 22, to which the support column 21 is connected. When the locking member 11 locks against the clamping member 31, the locking member 11 attracts the support base 22 through suction, thereby generating the first locking force mentioned above between the locking member 11 and the support base 22, thus completing the locking of the support base 22 by the locking member 11. This arrangement, using suction to achieve locking between the locking member 11 and the support base 22, makes locking between them more convenient. Furthermore, the support base 22 increases the contact area between the support assembly 2 and the locking member 11, thereby increasing the stability of the locking between them.

[0050] In some embodiments, the locking element 11 can be an electromagnet, and the support base 22 itself is made of non-metallic material, with a metal layer 23 embedded at its bottom. The metal layer 23 can be made of iron. When the electromagnet is energized, it attracts the metal layer 23 at the bottom of the support base 22, locking the relative position between the electromagnet (locking element 11) and the support base 22. When the electromagnet is de-energized, the attractive force between the electromagnet and the support base 22 disappears, and the first locking force is released.

[0051] Furthermore, refer to Figure 4-7 The support column 21 and the support base 22 are slidably connected, and the sliding direction is along the direction of approaching or moving away from the locking member 11. An auxiliary member 4 is provided between the support column 21 and the locking member 11. When the locking member 11 releases its lock on the support base 22, the auxiliary member 4 adheres to the locking member 11 through attraction, so that a second locking force is generated between the support column 21 and the locking member 11. In some embodiments, the auxiliary member 4 is a magnetic block and the locking member 11 is an electromagnet. Thus, when the electromagnet (locking member 11) is de-energized, the first locking force between the electromagnet (locking member 11) and the support base 22 is released. At this time, the magnetic block (auxiliary member 4) is attracted to the ferromagnetic component in the locking member 11 or the ferromagnetic structure connected to it through magnetic attraction, so that the second locking force mentioned above is generated between the support column 21 and the electromagnet (locking member 11), thereby maintaining the relative position between the support assembly 2 and the electromagnet (locking member 11). It should be noted that the support base 22 of this application is made of non-metallic material. When the magnetic block (auxiliary member 4) moves in the inner cavity of the support base 22, whether it is close to or away from the locking member 11, no attraction force is generated between the magnetic block (auxiliary member 4) and the support base 22, and no interference is generated on the sliding stroke of the magnetic block (auxiliary member 4).

[0052] Furthermore, after the electromagnet (locking member 11) is energized, a magnetic field distribution with the same magnetization direction is formed at the auxiliary member 4, causing a repulsive force between the auxiliary member 4 and the locking member 11, thereby driving the auxiliary member 4 to move away from the locking member 11, and driving the support column 21 to push out towards the steering column housing 5, so as to release the magnetic attraction locking state between the auxiliary member 4 and the locking member 11, and restore the first locking force between the locking member 11 and the support base 22.

[0053] In some implementations, refer to Figure 4-6 The support base 22 is hollow, and the support column 21 and the support base 22 are inserted into each other, thereby realizing the sliding connection between the support column 21 and the support base 22.

[0054] When repairing the steering column cover 5, refer to Figure 4-6The steering column housing 5 and the support column 21 may be stepped on opposite sides, with the steering column housing 5 having a first stepped surface 54 and a second stepped surface 55. This requires the support column 21 that mates with the mounting hole 53 on the first stepped surface 54 and the support column 21 that mates with the mounting hole 53 on the second stepped surface 55 to have different heights. To solve this problem, when the locking member 11 locks the support seat 22, a thrust is generated between the auxiliary member 4 and the locking member 11. The auxiliary member 4 is used to push the support column 21 toward the steering column housing 5 to be repaired. In some embodiments, the auxiliary member 4 is a magnetic block, and the locking member 11 is an electromagnet. When the electromagnet (locking member 11) is energized, it attracts the support base 22. The magnetic poles of the side of the electromagnet (locking member 11) facing the magnetic block (auxiliary member 4) are the same as those of the side of the magnetic block (auxiliary member 4) facing the electromagnet (locking member 11). A repulsive force is formed between the electromagnet (locking member 11) and the magnetic block (auxiliary member 4), thereby completing the pushing of the magnetic block (auxiliary member 4) against the support column 21.

[0055] With this configuration, when the locking member 11 locks the support base 22, the support column 21 is pushed against the steering column housing 5 under the action of the auxiliary member 4, so that the support column 21 can slide relative to the support base 22 until it stops sliding after it is engaged with the mounting hole 53. This allows multiple support columns 21 to adapt to mounting holes 53 in various different height areas.

[0056] Furthermore, refer to Figure 4-6 The clamping assembly 3 also includes a fixing member 32, which is connected to the clamping member 31. The locking member 11 adheres to the fixing member 32 through suction to lock the position of the fixing member 32. With this configuration, locking between the locking member 11 and the fixing member 32 is relatively convenient, and after the locking member 11 releases its lock on the fixing member 32, the fixing member 32 can also move relatively easily relative to the locking member 11.

[0057] Furthermore, when the locking member 11 locks the support base 22 with the first locking force, the locking member 11 simultaneously locks the fixing member 32. When the locking member 11 releases its lock on the support base 22, it also releases its lock on the fixing member 32. In this embodiment, the fixing member 32 can be made of ferromagnetic material, while the locking member 11 can still be an electromagnet. Therefore, by combining the above, the simultaneous locking or releasing of the support base 22 and the fixing member 32 can be achieved simply by switching the electromagnet on and off, greatly reducing additional parts and making the overall trimming fixture more compact.

[0058] Furthermore, refer to Figure 4-6The clamping member 31 includes a vertical rod 311, a connecting rod 312, and a clamping rod 313 connected in sequence. The vertical rod 311 and the clamping rod 313 are spaced apart, and the connecting rod 312 is located between the vertical rod 311 and the clamping rod 313. The vertical rod 311 is connected to the fixing member 32. The clamping rod 313 is used to extend into the cavity 51 of the steering column housing 5 to clamp the steering column housing 5. The vertical rod 311 is located outside the steering column housing 5. With this arrangement, when the clamping member 31 clamps the steering column housing 5, it presents an inverted "U" shape. The clamping rod 313 extends into the cavity 51 of the steering column housing 5. The clamping rod 313 and the vertical rod 311 are located on both sides of the edge of the steering column housing 5, respectively. The clamping member 31 as a whole only interferes with one side edge of the steering column housing 5, thereby reducing the number of times the clamping member 31 needs to be re-fixed later.

[0059] Furthermore, refer to Figure 4-6 The end of the clamping rod 313 is spherically shaped, and the spherical surface of the end of the clamping rod 313 contacts the steering column housing 5 to be repaired. With this arrangement, when the clamping rod 313 clamps the steering column housing 5, it can greatly reduce the damage to the steering column housing 5 caused by the clamping rod 313.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
