Description

Technical Field

[0001] This utility model relates to the field of steering gear housing processing technology, and in particular to a cutting and chamfering mechanism for processing steering gear housings. Background Technology

[0002] The function of the steering gear is to appropriately transform the steering torque and steering angle from the steering wheel (mainly by reducing speed and increasing torque) and then output them to the steering tie rod mechanism, thereby turning the car. Therefore, the steering gear is essentially a speed reduction transmission device. There are many types of steering gears, such as rack and pinion, recirculating ball, worm crank and pin, power steering, etc. When machining the steering gear housing, it is necessary to cut and chamfer it.

[0003] Among them, the existing chamfering equipment has a fixed chamfering depth when in use, which means that the chamfering process does not have a depth adjustment function. As a result, the chamfering equipment cannot adjust the chamfering depth according to the processing requirements of the steering gear housing, which limits the chamfering process and fails to meet the needs of customers.

[0004] Therefore, those skilled in the art have provided a cutting and chamfering mechanism for machining steering gear housings to solve the problems mentioned in the background art. Utility Model Content

[0017] Optionally, an anti-loosening washer is provided on one side of the limiting nut, and the outer surface of the anti-loosening washer is tightly fitted to the connection between the limiting nut and the movable frame.

[0018] By adopting the above technical solution, the anti-loosening washer can easily increase the friction between the limit nut and the movable frame, thereby improving the stability of the clamping and limiting.

[0033] In this embodiment: By setting up a concave frame 1, a rotating shaft 2, a chuck 3, and a drive assembly 14, the present invention can conveniently clamp and limit the rotation of the steering gear housing. By setting up an electric cylinder 4, a lifting plate 5, a vertical plate 6, a movable frame 7, a concave plate 8, a first rotary motor 9, a chamfering cutter 10, a stud 11, a limiting nut 12, and a scale 13, the steering gear housing can be conveniently chamfered. At the same time, the chamfering depth can be adjusted. By setting up the above structure, the chamfering depth adjustment function can be provided, thereby meeting the customer's usage needs and avoiding the limitations of chamfering.

[0034] Example 2:

[0035] Reference Figure 2The drive assembly 14 includes a second rotary motor 141. The output end of the second rotary motor 141 is fixedly connected to a drive gear 142. The right end of the rotating shaft 2 passes through the concave frame 1 and is fixedly connected to a driven gear 143. The drive gear 142 and the driven gear 143 mesh. A protective box 15 is fixedly connected to the right side of the concave frame 1.

[0036] In this embodiment: By setting a second rotary motor 141, a driving gear 142 and a driven gear 143, the present invention can facilitate the rotation of the rotating shaft 2.

[0037] The implementation principle of this utility model is as follows: When it is necessary to chamfer the steering gear housing, the operator clamps and limits the steering gear housing using the chuck 3. Then, according to the chamfer depth requirement of the steering gear housing, the operator moves the movable frame 7, so that the movable frame 7 drives the concave plate 8, the first rotary motor 9 and the chamfering cutting blade 10 to move vertically to the specified value position on the scale 13. Then, the operator rotates the limit nuts 12 on both sides in sequence, so that the limit nuts 12 drive the anti-loosening washer 17 to rotate and move on the threaded part of the stud 11 and press and contact the movable frame 7 at the connection point, thereby limiting the movable frame 7 and completing the adjustment of the chamfer depth of the chamfering cutting blade 10.

[0038] Next, the operator activates the external controllers of the first rotary motor 9 and the second rotary motor 141, causing the output of the first rotary motor 9 to drive the chamfering cutter 10 to rotate. Simultaneously, the output of the second rotary motor 141 drives the drive gear 142 to rotate, which in turn drives the driven gear 143 to rotate. The driven gear 143 then drives the rotating shaft 2 to rotate, which in turn drives the chuck 3 to rotate. This causes the chuck 3 to rotate the steering gear housing. Next, the operator activates the external controller of the electric cylinder 4, causing the telescopic end of the electric cylinder 4 to move the lifting plate 5 downwards. The lifting plate 5 then moves the vertical plate 6 and the movable frame 7 downwards, causing the movable frame 7 to move the concave plate 8 and the first rotary motor 9 downwards to a designated position. This allows the chamfering cutter 10, driven by the first rotary motor 9, to contact the rotating steering gear housing, thus achieving the chamfering of the steering gear housing. This device is simple to operate and allows for easy adjustment of the chamfering depth, meeting customer needs and avoiding limitations in chamfering.
