Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile part processing, and specifically relates to a multi-angle positioning press fitting device. BACKGROUND

[0002] In traditional manufacturing, the knuckle, as an important component of the automobile steering system, its machining precision and efficiency are directly related to the performance and safety of the whole vehicle. The knuckle has a complex structure, usually containing multiple planes, hole positions and profile surfaces that need to be precisely machined. These features are often distributed at different angles and positions. Therefore, the processing of the knuckle puts high requirements on the flexibility and multifunctionality of the equipment.

[0003] However, the traditional press fitting equipment is usually single in design, mainly focusing on realizing a certain specific process or a certain angle of machining task. Such equipment usually uses fixed tooling fixtures and tool paths, which is difficult to adapt to the multi-angle and multi-feature machining requirements of the knuckle. Specifically, the traditional press fitting equipment has the following limitations:

[0004] Limited machining angle: due to the limitations of equipment structure and tooling design, the traditional press fitting equipment can usually only process a certain specific angle or surface of the knuckle. If other angle features need to be processed, the tooling must be adjusted, the fixture must be replaced, or even the knuckle must be removed from the equipment and reinstalled at another angle, which not only consumes time and effort, but also increases the risk of processing errors.

[0005] Low processing efficiency: due to the need for multiple installations and adjustments, the traditional press fitting equipment is low in efficiency when processing the knuckle. Each time the equipment is reinstalled, accurate centering and positioning are required, which not only prolongs the processing cycle, but also may cause inconsistencies in processing accuracy.

[0006] High cost: multiple installations and adjustments not only increase labor costs, but also increase material costs due to the rising scrap rate caused by processing errors. In addition, the traditional press fitting equipment often lacks intelligent and automated functions, further limiting production efficiency and cost control. INVENTION CONTENTS

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the following will combine the drawing in the utility model embodiment, and the technical scheme in the utility model embodiment is clearly and completely described, obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment. The components of the utility model embodiment described and shown in the drawing here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiment of the utility model provided in the drawing is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the utility model.

[0027] It should be noted that: similar signs and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0028] In the above description of this utility model, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0030] Please see Figures 1-4 This utility model provides a technical solution: a multi-angle positioning and pressing device, including a base 1, a fixed seat 2 detachably connected to the top surface of the base 1, a bearing seat 3 provided on the top surface of the fixed seat 2, the bearing seat 3 being used to position the steering knuckle 4, and the top surfaces of both the fixed seat 2 and the bearing seat 3 being inclined.

[0031] A hydraulic cylinder 5 is mounted on the bottom surface of the base 1. A piston rod 6 is connected to the output direction of the hydraulic cylinder 5. The end of the piston rod 6 away from the hydraulic cylinder 5 passes through the top surface of the base 1. A fixed seat 2 and a bearing seat 3 are sleeved on the piston rod 6. A first limiting component 8 for limiting the steering knuckle 4 is also sleeved on the piston rod 6.

[0032] When machining the steering knuckle 4, firstly, the bearing hole of the steering knuckle 4 is precisely assembled onto the bearing seat 3 on the top surface of the fixed seat 2 through the piston rod 6, ensuring that there is an appropriate clearance fit between them. The fixed seat 2 and the bearing seat 3 are tilted in the same direction, and the steering knuckle 4 is also tilted after being installed on the bearing seat 3, thus exposing all the angles of the multiple parts of the steering knuckle 4 that need to be machined. Then, the first limiting component 8 is fitted onto the piston rod 6, and the hydraulic cylinder 5 is activated. The hydraulic cylinder 5 controls the piston rod 6 to change from an extended state to a retracted state. During the retraction process, the piston rod 6 presses against the first limiting component 8. Under the combined action of the first limiting component 8 and the fixed seat 2, the steering knuckle 4 is clamped and fixed. Finally, the steering knuckle 4 is machined at multiple angles using machining equipment.

[0033] In this process, the fixed seat 2 with an inclined angle cooperates with the bearing seat 3 to securely install the steering knuckle 4 on the bearing seat 3 in an inclined posture, ensuring that the part to be processed is fully exposed, thereby reducing the number of clamping operations on the steering knuckle 4 and reducing the labor intensity of the workers, while improving the processing accuracy of the steering knuckle 4.

[0034] In this embodiment: the first limiting component 8 includes a first limiting block 81 and a second limiting block 82. The first limiting block 81 is provided with multiple first limiting rods 83, and the top surface of the first limiting block 81 abuts against the bottom surface of the second limiting block 82.

[0035] In this technical solution, the bearing hole of the steering knuckle 4 is provided with connecting holes around it that are adapted to the second first limiting rod 83.

[0036] In use, after the steering knuckle 4 is installed on the bearing seat 3, the first limiting block 81 and the second limiting block 82 are respectively sleeved on the piston rod 6, and the first limiting rod 83 on the bottom surface of the first limiting block 81 is inserted into the connecting hole on the steering knuckle 4, so as to facilitate the pressing and fixing of the steering knuckle 4 and prevent the first limiting block 81 from loosening.

[0037] In this embodiment: a second limiting rod 84 is connected to the top surface of the bearing seat 3. One end of the second limiting rod 84 is connected to the top surface of the bearing seat 3, and the other end extends upward. The first limiting block 81 and the second limiting block 82 are provided with limiting holes 85 that are adapted to the second limiting rod 84.

[0038] When the steering knuckle 4 is installed and fixed, and the first limiting block 81 and the second limiting block 82 are fitted on it, the limiting holes 85 opened on the first limiting block 81 and the second limiting block 82 are aligned with the second limiting rod 84, so that the first limiting block 81 and the second limiting block 82 can accurately position the steering knuckle 4 and improve the machining accuracy of the steering knuckle 4.

[0039] In this embodiment: the end of the piston rod 6 away from the oil cylinder 5 is connected to a first threaded rod 7, and a bolt 9 is threaded on the first threaded rod 7.

[0040] In this technical solution, a first through hole is provided on the first limiting block 81, and the diameter of the first through hole is larger than the diameter of the first threaded rod 7 and the piston rod 6. A second through hole is provided on the second limiting block 82, and the diameter of the second through hole is larger than the diameter of the first threaded rod 7 and smaller than the diameter of the piston rod 6. An opening communicating with the second through hole is provided on the second limiting block 82, and the diameter of the bolt 9 is larger than the diameter of the second through hole.

[0041] In use, first screw the threaded portion of bolt 9 onto the first threaded rod 7, ensuring its position is above the second limiting block 82. Then, place the first limiting block 81 and the second limiting block 82 onto the piston rod 6. Next, activate the hydraulic cylinder 5, which controls the piston rod 6 to gradually transition from its extended state to its retracted state. During this process, the piston rod 6 synchronously pulls the first threaded rod 7 and the connected bolt 9 downwards. This movement continues until the bottom surface of bolt 9 contacts the top surface of the second limiting block 82, generating a resisting force. At this point, combined with the action of the fixing seat 2, the upper and lower sides of the steering knuckle 4 will be firmly clamped and fixed.

[0042] In this embodiment: the base 1 has a plurality of first threaded holes 10, and the bottom surface of the fixed base 2 has a plurality of second threaded holes 11 that are adapted to the first threaded holes 10. The first threaded holes 10 and the second threaded holes 11 are internally threaded with a second threaded rod 12.

[0043] After multiple batches of steering knuckles 4 are processed, the fixed seat 2 and bearing seat 3 will wear out. Therefore, in order to ensure the clamping state of the steering knuckle 4 during the processing, the worn fixed seat 2 and bearing seat 3 need to be replaced. This can be done by rotating the second threaded rod 12 to remove it from the first threaded hole 10 and the second threaded hole 11, thereby removing the fixed seat 2 and bearing seat 3 from the base 1 for replacement.

[0044] In this embodiment, a second limiting component 13 is also included. The second limiting component 13 is installed on the top surface of the base 1, and the mounting hole of the steering knuckle 4 is fitted onto the second limiting component 13.

[0045] When assembling the steering knuckle 4, it is necessary to ensure that the bearing hole of the steering knuckle 4 is precisely aligned and inserted into the bearing housing 3. At the same time, the mounting hole on the steering knuckle 4 must also be properly fitted onto the second limiting component 13. This installation method not only effectively limits the range of motion of the steering knuckle 4, but also significantly enhances the stable positioning of the steering knuckle 4 in the device, thereby helping to improve the accuracy of machining operations.

[0046] In this embodiment: the second limiting component 13 includes a mounting base 131 and a third limiting rod 132. The third limiting rod 132 is mounted on the top surface of the mounting base 131 and is in an inclined state.

[0047] When the steering knuckle 4 is assembled onto the inclined fixed seat 2 and bearing seat 3, it will also tilt accordingly. Simultaneously, the mounting holes on the steering knuckle 4 will be inclined and fitted onto the equally inclined third limiting rod 132. This design not only ensures the stability and accuracy of the steering knuckle 4 during assembly, but also provides additional support and positioning through the inclined limiting rod, further enhancing the stability and machining accuracy of the entire assembly structure.

[0048] 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 it. 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 spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
