[0001] This invention relates to the field of steering gear housing positioning device technology, specifically a five-axis linkage floating positioning precision machining device for steering gear housing. Background Technology

[0002] The steering gear is the core component of a car's steering system. It is the device through which the driver controls the vehicle's steering using the steering wheel.

[0010] In a preferred embodiment, the present invention may be further configured such that: a circular hole is provided in the end of the protective plate facing the column head, and a second bolt is inserted into the circular hole, and the second bolt is threaded into the column head.

[0011] In a preferred embodiment, the present invention can be further configured such that: the number of stabilizing pads is four, and the outer wall of the top of the stabilizing pad has an arc-shaped structure, which is used to provide stabilizing support for the arc surface of the inner side of the shell blank after inversion.

[0012] In a preferred embodiment, the present invention may be further configured such that: the stabilizing pad has an insertion hole inside, and the second leg and the third leg are adapted to pass through the insertion hole.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a five-axis linkage floating positioning precision machining device for a steering gear housing. Example 1:

[0024] Combination Figures 1 to 9 As shown, the present invention provides a five-axis linkage floating positioning precision machining device for a steering gear housing, including a lifting mechanism 100, an in-housing positioning mechanism 200 mounted on the lifting mechanism 100, a housing hole alignment mechanism 300 mounted on the in-housing positioning mechanism 200, and a housing blank 400 clamped in the in-housing positioning mechanism 200 and the housing hole alignment mechanism 300. The in-housing positioning mechanism 200 is used to quickly fix and clamp the undercut housing blank 400. The housing hole alignment mechanism 300 is used to control and locate the undercut housing blank 400 and enhance the stability of the housing blank 400 after clamping. The lifting mechanism 100 is used to adjust the angle of the clamped housing blank 400 to facilitate the subsequent machining of holes.

[0025] The internal positioning mechanism 200 includes a column head 210, a column 2102 installed inside the column head 210, a second hydraulic component 220 installed inside the column head 210, a slide 240 movably installed inside the column 2102, and a hydraulic rod inside the second hydraulic component 220 installed inside the slide 240. A base plate 250 is installed outside the column head 210, and two protective plates 2502 are provided on the top of the base plate 250. A stabilizing pad 270 is movably installed inside the two protective plates 2502. The outer wall of the stabilizing pad 270 has a recess... An arc-edge sliding roller 2701 is movably installed in the groove. A top-edge sliding roller 2702 is movably installed in the groove at the top of the stabilizing pad 270. A clamp 2703 is inserted into the bottom of the stabilizing pad 270. A horizontally placed reinforcing spring 280 is connected between the stabilizing pad 270 and the end of the base plate 250. A third support leg 2602 is movably installed in the clamp 2703. A first support leg 260 is movably installed on the slide block 240, and a second support leg 2601 is movably installed on the first support leg 260 and the third support leg 2602. There are four stabilizing pads 270, and the outer wall of the top of the stabilizing pad 270 is arc-shaped, which is used to provide stabilizing support for the arc surface inside the shell blank 400 after inversion. The shell hole alignment mechanism 300 includes a truss 310 set at the bottom of the column head 210, a horizontal plate 320 movably installed inside the truss 310, a side hole positioning frame 340 installed inside the horizontal plate 320, a vertical rod 350 fixedly installed inside the side hole positioning frame 340, and a shaft hole positioning frame 360 ​​installed on the vertical rod 350.

[0026] The second hydraulic component 220 is operated via the cloud until the hydraulic rod inside the second hydraulic component 220 retracts and drives the slide 240 to descend. The four first legs 260, which are movably mounted on the slide 240, will push the second legs 2601 and the third legs 2602 to retract in a coordinated manner. Finally, the four evenly distributed stabilizing pads 270 will move laterally along the inner side of the four sets of guard plates 2502 until the four stabilizing pads 270 retract to their minimum extent. Then, the side hole positioning frame 340 is controlled to flip outward along the horizontal plate 320. Because the damping of the extended vertical rod inside the side hole positioning frame 340 and the internal hole of the horizontal plate 320 is large, the rotated side hole positioning frame 340 will maintain a constant angle. Then, the shell blank 400 is inverted and placed outside the retracted four stabilizing pads 270. Next, the second hydraulic component 220 is operated until the hydraulic rod inside the second hydraulic component 220 is reset and extended. Under the push of the above-mentioned linkage components, the four evenly distributed stabilizing pads 270 will quickly expand outward and quickly calibrate and fix the shell blanks 400 with different diameters and widths. Then, the side hole positioning frame 340 is reset until the cylindrical end inside the shaft hole positioning frame 360 ​​is aligned and pressed with the top of the inverted shell blank 400. As the position of the shaft hole positioning frame 360 ​​is determined, the side hole positioning frame 340 will also remain parallel to the shaft hole positioning frame 360, which facilitates the quick positioning of the control position of the side of the shell blank 400. This process can be used in conjunction with an external drilling device to accurately locate the top and side holes of the inverted shell blank 400, facilitating efficient drilling operations by the external drilling device. At the same time, it can enhance the straightness of the internal hole walls of the shell blank 400 by preventing the drill bit from shaking after it enters the shell blank 400. Example 2:

[0027] Combination Figure 2 , Figure 3 as well as Figure 7 As shown, based on Embodiment 1, the lifting mechanism 100 includes a load-bearing frame 110, a load-bearing shaft 1101 installed inside the load-bearing frame 110, a lever arm 130 movably installed on the guide rod at the outer end of the load-bearing frame 110, a positioning shaft 1301 inserted into the slot inside the lever arm 130, and a first hydraulic component 120 connected to the load-bearing shaft 1101 and the positioning shaft 1301, a bearing 140 installed on the rod segment at the top of the lever arm 130, and a combination bolt 1302 installed in the rod segment at the top of the lever arm 130. A double-acting screw 330 is movably installed inside the plate end at the bottom of the truss 310. A gear disk 3101 is fixedly installed on the truss 310, and the threaded section of the double-acting screw 330 is threaded inside the plate end at the bottom of the horizontal plate 320. The truss 310 is installed outside the bearing 140. The side hole positioning frame 340 is composed of an extended vertical rod and a T-shaped plate segment. The cylindrical end of the T-shaped plate segment is provided with a marking hole for controlling and positioning the side of the shell blank 400 after the inverted shape. The cylindrical end of the shaft hole positioning frame 360 ​​is provided with a hole, and the cylindrical end of the shaft hole positioning frame 360 ​​is aligned with the top of the shell blank 400 after the inverted shape for marking and positioning the shaft hole at the top of the shell blank 400.

[0028] Preferably, the plate end of the load-bearing frame 110 away from the lever arm 130 is provided with two elliptical slots, and the plate end of the load-bearing frame 110 away from the lever arm 130 is fixedly installed on the workbench or machine tool by expansion bolts, and the pipe section at the bottom of the column head 210 is inserted into the rod section at the top of the lever arm 130, and the column head 210 and the rod section at the top of the lever arm 130 are fixed by combination bolts 1302, and the gear 2302 is adapted to mesh with the gear disk 3101; After the motor 2301 starts and runs, its internal transmission shaft, in conjunction with the gear 2302, will drive the gear disk 3101 and the truss 310. Finally, the truss 310 and the horizontal plate 320 will rotate at a constant speed around the bearing 140. The horizontal plate 320, after rotating at a constant speed, will drive the side hole positioning frame 340, the vertical rod 350 and the shaft hole positioning frame 360 ​​to accurately locate the holes along the outer surface of the inverted shell blank 400. This ensures that the shell blank 400 is securely clamped, while also reducing the problem of large-area interference to the outer surface of the inverted shell blank 400. Example 3:

[0029] Combination Figures 3 to 9 As shown, in the above embodiment, a housing 230 is fixedly installed at the bottom of the column head 210, a motor 2301 is fixedly installed inside the housing 230, and a gear 2302 is fixedly installed on the drive shaft inside the motor 2301. The internal thread of the column head 210 is fitted with two first bolts 2101, and the first bolts 2101 are used to fix the second hydraulic component 220; The side of the column head 210 is provided with a vertical groove, and the rectangular protrusion at the inner end of the base plate 250 is adapted to be snapped into the vertical groove. Four symmetrically distributed studs 2501 are fixedly installed on the top of the inner end of the base plate 250, and a limiting transverse groove is provided inside the base plate 250. The first leg 260 and the second leg 2601 are adapted to pass through the limiting transverse groove. A round hole is provided in the end of the guard plate 2502 facing the column head 210, and a second bolt 2503 is inserted into the round hole. The second bolt 2503 is threaded into the column head 210. The stabilizing pad 270 has an insertion hole inside, and the second leg 2601 and the third leg 2602 are adapted to pass through the insertion hole.

[0030] Preferably, the stabilizing pad 270 has a fan-shaped structure, and its outer wall and top surface are both smooth coated. The arc-edge sliding roller 2701 and the top-edge sliding roller 2702 are both composed of stainless steel guide rods and stainless steel rotating rollers. The diameter of the stainless steel rotating roller inside the top-edge sliding roller 2702 is half the diameter of the stainless steel rotating roller inside the arc-edge sliding roller 2701, used to reduce the frictional resistance on the inner wall of the shell blank 400 after the inverted shape. When the four stabilizing pads 270 press against the inner wall of the shell blank 400... After being subjected to pressure, under the pressure of multiple arc-edge sliding rollers 2701 and top-edge sliding rollers 2702, the shell blank 400 will rotate in conjunction with the side hole positioning frame 340 and the shaft hole positioning frame 360. When the four stabilizing pads 270 continue to expand outward and fix the shell blank 400, the side hole positioning frame 340 and the shaft hole positioning frame 360 ​​will rotate along the outside of the shell blank 400. At this time, the shell blank 400 will not move in conjunction with the side hole positioning frame 340 and the shaft hole positioning frame 360 ​​after being overturned. The inner end of the reinforcing spring 280 is fixedly installed on the stabilizing pad 270, and the outer end of the reinforcing spring 280 is fixedly installed on the end of the base plate 250. The bottom surfaces of the two guard plates 2502 are welded to the two sides of the top of the base plate 250.

[0031] The working principle and usage process of this invention: The load-bearing frame 110 is fixedly installed on the side of the workbench using expansion bolts. Then, the first hydraulic component 120 is operated via the cloud. As the hydraulic sub-rod inside the first hydraulic component 120 contracts, it drives the positioning shaft 1301 and the lever arm 130 to flip upward. When the lever arm 130 is in a vertical state with the load-bearing frame 110, the side hole positioning frame 340, the vertical rod 350 and the shaft hole positioning frame 360 ​​are controlled to flip outward. Then, the shell blank 400 is inverted until it is placed outside the four evenly distributed stabilizing pads 270. The arc surface at the top of the stabilizing pad 270 fits against the inner wall of the shell blank 400. Then, the second hydraulic component 220 is activated. As the hydraulic rod inside the second hydraulic component 220 extends outward, the slide 240 installed on the hydraulic rod is pressed and drives the four first legs 260 to rise. The first legs 260 pull the second legs 2601 outward. The outward-extending second legs 2601 is pressed and pushes the third legs 2602 to extend laterally. Finally, the chuck 2703 and the stabilizing pads 270 will move laterally along the inner side of the two adjacent guard plates 2502. After the four stabilizing pads 270 extend outward at the same speed and at equal distances, the inverted shell blank 400 can be quickly calibrated and locked. After the shell blank 400 is locked and fixed, the side hole positioning frame 340, the vertical rod 350 and the shaft hole positioning frame 360 ​​are reset. During this process, the rotating bidirectional lead screw 330 is used to push the horizontal plate 320 until the horizontal plate 320 and the truss 310 are adapted to the shell blanks 400 with different diameters and widths, until the columnar end of the top plate of the side hole positioning frame 340 and the columnar end of the outer end of the shaft hole positioning frame 360 ​​are pressed against the side and top of the shell blank 400 respectively. At this time, the shell blank 400 with the inverted structure can be tightened in multiple directions. At this time, the cylindrical end in the shaft hole positioning frame 360 ​​and the cylindrical end in the side hole positioning frame 340 can provide accurate drilling marks for the drilling equipment, ensuring that the internal hole wall of the shell blank 400 always maintains a vertical structure, and avoiding the straightness of the internal hole of the shell blank 400 affected by the downward movement of the drill bit and tilting under the action of external force. During this period, the cloud-based motor 2301 is used to drive the gear disk 3101 and the truss 310 to rotate at a constant speed around the bearing 140 as the axis. The cylindrical end in the shaft hole positioning frame 360 ​​achieves stable rotation without leaving the center position of the top of the shell blank 400, while the cylindrical end in the side hole positioning frame 340 will quickly locate the hole along the side of the shell blank 400, ensuring the accuracy of the subsequent hole spacing and hole position on the side of the shell blank 400. Meanwhile, in order to improve the automation of the positioning device when working with the existing automatic drilling robot, the first hydraulic component 120 is operated. Its internal hydraulic rod can control the overall tilt angle of the internal positioning mechanism 200. The tilted internal positioning mechanism 200 and the shell blank 400 can work with the existing robot to achieve multi-angle and adaptable drilling operations.

[0032] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
