Description

Technical Field

[0001] This utility model relates to the field of steering gear manufacturing technology, and in particular to a steering gear housing milling processing device. Background Technology

[0002] As a crucial component in automobiles, the steering gear requires multiple clamping and adjustment of the machining plane during milling due to the presence of multiple holes distributed at different angles within the housing. A search revealed CN222327435U, which discloses a machining fixture for automotive steering gears. While this device can quickly clamp the gears and adjust the spacing between the limiting blocks to accommodate steering gears of different lengths, it still suffers from the following problems: Each time the machining angle is adjusted, the workpiece needs to be loosened, re-aligned, and then clamped again. This process, due to frequent clamping, can easily lead to the accumulation of errors, resulting in a decrease in machining accuracy. When adjusting the machining angle, the lack of angle markings to assist in the adjustment requires the use of auxiliary instruments, which wastes a lot of machining time and reduces machining efficiency. Therefore, a milling device for steering gear housing is proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for repeated clamping leading to reduced machining accuracy and the lack of angle markings to assist in adjusting machining angles. Therefore, this invention proposes a milling device for steering gear housings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A milling apparatus for steering gear housing includes a base, on the top of which a support seat and two guide rails are fixedly connected; A retaining ring is fixedly connected to the top of the support base; The rotary adjustment mechanism includes a gear ring rotatably connected to the inner side of the circumference of a fixed ring, a spur gear rotatably connected to one side of the fixed ring, an angle scale fixedly connected to the other side of the fixed ring, an adjustment handle fixedly connected to one end of the spur gear, the gear ring and the spur gear meshing with each other, and a rotary clamping assembly installed on the inner side of the circumference of the gear ring for fixing the steering gear housing. An auxiliary clamping mechanism is installed on top of the two guide rails to assist in securing the steering gear housing.

[0005] In one possible design, the rotary clamping assembly includes a rotating ring rotatably connected to the inner circumference of a gear ring, and multiple pairs of guide tubes are fixedly connected to the inner circumference of the gear ring, with a radial push plate slidably connected to one end of each pair of guide tubes.

[0006] In one possible design, a motor is fixedly connected to one end of the gear ring, and a bevel gear is fixedly connected to one end of the motor output shaft. The two ends of the rotating ring are respectively provided with conical teeth and equidistant radial spiral grooves, and the bevel gear meshes with the conical teeth.

[0007] In one possible design, the centripetal pusher includes an arc-shaped pressure plate, a connecting block, two guide rods, and multiple equidistant arc-shaped sliders. The connecting block and one side of the arc-shaped pressure plate are fixed together. The two guide rods and multiple equidistant arc-shaped sliders are all fixedly connected to the surface of the connecting block. The two guide rods are slidably connected to the inner circumference of a corresponding pair of guide tubes. The multiple equidistant arc-shaped sliders cooperate with equidistant radial spiral grooves.

[0008] In one possible design, the rotary clamping assembly includes a sliding seat slidably connected to the top of two guide rails, a support plate fixedly connected between the two sides of the sliding seat, two pairs of supports fixedly connected to one side of the support plate, a bidirectional screw rotatably connected between each pair of supports, and two symmetrically arranged arc-shaped clamping plates threaded between the two bidirectional screws.

[0009] In one possible design, each arc-shaped clamp is threaded to the corresponding bidirectional screw at both ends. The threads of the two arc-shaped clamps are opposite in direction and symmetrically distributed. One side of one arc-shaped clamp is threaded with two set screws, and the end faces of the two set screws abut against the outer circumference of the bidirectional screw.

[0010] In one possible design, a handle is fixedly connected to one end of each of the two bidirectional screws.

[0011] In one possible design, a ring-shaped protective cover is fixedly connected to one side of the retaining ring.

[0012] In this application: When the motor is started, its output shaft drives the bevel gear to rotate. The bevel gear meshes with the conical teeth at one end of the rotating ring, thereby converting the horizontal rotational motion of the motor into the rotation of the rotating ring inside the gear ring. The equidistant radial spiral grooves at the other end of the rotating ring rotate accordingly. The arc-shaped sliders fixed on multiple radial push plates are respectively embedded in these spiral grooves. When the spiral grooves rotate, they drive all the radial push plates to move radially in a straight line along the guide tube at equal distances towards the center of the steering gear housing until the steering gear housing is initially clamped. Since the spiral grooves are equidistant and radially designed, the arc-shaped pressure plates on the radial push plates fix the steering gear housing in the center position. After clamping is completed, when adjusting the angle later, it is not necessary to release the rotating clamping assembly from the driver housing, avoiding the risk of reduced workpiece machining accuracy due to repeated clamping. Rotating the handle drives the bidirectional screw to rotate. Since the internal threads of the two arc-shaped clamping plates are in opposite directions, they will move towards or away from each other on the bidirectional screw, thereby clamping the workpiece from both sides and providing strong auxiliary clamping to further clamp the steering gear housing. Tighten the set screw so that its end is tightly against the circumferential surface of the bidirectional screw. Through friction, the clamping mechanism is prevented from rotating under machining vibration. The locking provided by the auxiliary clamping mechanism ensures that the steering gear housing does not rotate during the cutting process, which would reduce the machining accuracy. When it is necessary to adjust the workpiece machining angle, the operator can unlock the auxiliary clamping mechanism by rotating the handle. The operator can then turn the adjustment handle to drive the spur gear to rotate. The spur gear drives the meshing gear ring to rotate within the fixed ring. Since the entire rotating clamping assembly is integrated on the gear ring, the rotating clamping assembly and the steering gear housing can be regarded as a whole. When adjusting the angle, the operator can refer to the angle scale on the side of the fixed ring for precise angle positioning without the need for external measuring tools, which greatly improves the adjustment efficiency. After adjusting the angle, rotate the handle to lock the auxiliary clamping mechanism onto the steering gear housing again, and then you can process the next machining plane. For steering gear housings with a large length-to-diameter ratio, a movable auxiliary clamping mechanism can be used. This mechanism slides on the guide rail via a sliding seat and can be flexibly adjusted to a suitable support position.

[0013] Beneficial effects: In this utility model, the steering gear housing milling device uses components such as a radial push plate, a rotating ring, a gear ring, and a spur gear in cooperation. After the rotary clamping assembly completes the radial clamping of the steering gear housing, the adjustment handle can be rotated to drive the spur gear to rotate. Since the entire rotary clamping assembly is integrated on the gear ring, the rotary clamping assembly and the steering gear housing can be regarded as a whole, thereby adjusting the workpiece angle without having to release the rotary clamping assembly from the driver housing, avoiding lateral displacement of the workpiece due to repeated clamping, and greatly improving the machining accuracy of the workpiece. In this utility model, the steering gear housing milling device, through the coordinated use of components such as spur gear, gear ring, fixed ring, and angle scale, allows for precise angle positioning by referring to the angle scale on the side of the fixed ring when adjusting the workpiece rotation angle, without the need for external measuring tools, thus greatly improving the adjustment efficiency. In this invention, rotating the adjustment handle drives the rotating clamping component and the steering gear on the gear ring to rotate synchronously. There is no need to release the rotating clamping component from the driver housing, which improves the machining accuracy. During adjustment, the angle can be precisely positioned by referring to the angle scale on the side of the fixed ring, thus improving efficiency. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] In one implementation case, refer to Figures 1-6 A shell milling processing device includes: a base 1, with a support 2 and two guide rails 13 fixedly connected to the top of the base 1; In this embodiment, the fixing ring 5 is fixedly connected to the top of the support base 2; In particular, the rotary adjustment mechanism includes a gear ring 15 rotatably connected to the inner circumference of the fixed ring 5, a spur gear 16 rotatably connected to one side of the fixed ring 5, and an angle scale 501 fixedly connected to the other side of the fixed ring 5, which provides a reference when adjusting the rotation angle, eliminating the need for external measuring tools and greatly improving adjustment efficiency. One end of the spur gear 16 is fixedly connected to an adjustment handle 17, and the gear ring 15 and the spur gear 16 mesh with each other. A rotary clamping assembly is installed on the inner circumference of the gear ring 15 to fix the steering gear housing. An auxiliary clamping mechanism is installed on top of the two guide rails 13 to assist in fixing the steering gear housing.

[0018] It should be noted that the rotary clamping assembly includes a rotating ring 14 rotatably connected to the inner side of the toothed ring 15. Multiple pairs of guide tubes 20 are fixedly connected to the inner side of the toothed ring 15, and a radial push plate 4 is slidably connected to one end of each pair of guide tubes 20.

[0019] This application can be used in the field of steering gear manufacturing technology, or in other fields applicable to this application.

[0020] In another implementation case, refer to Figures 1-6 A milling device for steering gear housing is applied to the field of steering gear manufacturing technology. One end of the gear ring 15 is fixedly connected to a motor 19, and one end of the output shaft of the motor 19 is fixedly connected to a bevel gear 18. The two ends of the rotating ring 14 are respectively provided with bevel teeth 1401 and equidistant radial spiral grooves 1402. The bevel gear 18 meshes with the bevel teeth 1401 and drives the rotating ring 14 to rotate through the motor 19 to provide driving force.

[0021] In this embodiment, the centripetal push plate 4 includes an arc-shaped pressure plate 401, a connecting block 403, two guide rods 404, and multiple equidistant arc-shaped sliders 402. The connecting block 403 and one side of the arc-shaped pressure plate 401 are fixed together. The two guide rods 404 and multiple equidistant arc-shaped sliders 402 are all fixedly connected to the surface of the connecting block 403. The two guide rods 404 are respectively slidably connected to the inner circumference of a pair of corresponding guide tubes 20. The multiple equidistant arc-shaped sliders 402 cooperate with the equidistant radial spiral grooves 1402. When the rotating ring 14 rotates, it drives the centripetal push plate 4 to move centripetally and equally at equal intervals, ensuring that the steering gear housing and the rotating ring 14 are concentric and avoiding misalignment. During rotation, the steering gear housing will deviate, thereby reducing the machining accuracy.

[0022] In particular, the rotary clamping assembly includes a sliding seat 12 slidably connected to the top of the two guide rails 13, a support plate 11 fixedly connected between the two sides of the sliding seat 12, two pairs of supports 8 fixedly connected to one side of the support plate 11, a bidirectional screw 10 rotatably connected between each pair of supports 8, and two symmetrically arranged arc-shaped clamping plates 7 threadedly connected between the two bidirectional screws 10.

[0023] In addition, each arc-shaped clamp 7 is threaded to the corresponding bidirectional screw 10 at both ends. The threads of the two arc-shaped clamps 7 are opposite in direction and symmetrically distributed. One side of one arc-shaped clamp 7 is threaded with two set screws 9. The end faces of the two set screws 9 abut against the outer circumference of the bidirectional screw 10, and the position of the arc-shaped clamp 7 is locked by friction.

[0024] Each of the two bidirectional screws 10 has a handle 6 fixedly connected to one end, increasing the contact area with the worker's palm and making it easier for the worker to adjust.

[0025] It should be noted that a ring-shaped protective cover 3 is fixedly connected to one side of the fixed ring 5 to protect the internal mechanical transmission components such as the motor 19 from damage by external factors and to prevent accidental injury to personnel, thereby improving the service life and safety of the equipment.

[0026] However, as is well known to those skilled in the art, the working principle and wiring method of motor 19 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0027] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
