[0027] See also Figure 1-Figure 5 The present invention provides a steering cylinder inner bore honing device, comprising a base 100, a mounting base plate 101 mounted on the upper surface of the base 100, a plurality of hollow shafts 102 rotatably mounted on the upper surface of the mounting base plate 101, a plurality of through slots 103 coaxially arranged inside the hollow shafts 102, a first wedge block 104 disposed inside the through slots 103, a pressure ring 105 disposed on the upper side of the hollow shaft 102, a plurality of second wedge blocks 106 mounted on the lower surface of the pressure ring 105, the second wedge blocks 106 matching the first wedge blocks 104, and a fixing mechanism 200 disposed between the pressure ring 105 and the hollow shaft 102. A driving mechanism 300 capable of driving the plurality of hollow shafts 102 to rotate simultaneously is disposed on the upper surface of the mounting base plate 101. A U-shaped frame 107 is installed on the upper surface of the base 100, and a first hydraulic cylinder 108 is installed on the upper surface of the U-shaped frame 107. A cross plate 109 is installed at the end of the telescopic end of the first hydraulic cylinder 108. A plurality of connecting rods 110 are installed on the lower surface of the cross plate 109, and a honing head 111 is installed at the end of the connecting rod 110.

[0028] During use, multiple cylinders are first inserted into multiple hollow rotating shafts 102 respectively, and then the pressure ring 105 is pressed down to make the second wedge block 106 squeeze the first wedge block 104, and then drive multiple first wedge blocks 104 to clamp on the outside of the cylinder, and fix the position of the pressure ring 105 through the fixing mechanism 200, so as to achieve the purpose of fixing the cylinder, and then the driving mechanism 300 drives the multiple cylinders to rotate simultaneously, and starts the first hydraulic cylinder 108 to drive the cross plate 109 to descend, and the cross plate 109 drives multiple honing heads 111 to be inserted into the interior of the cylinder at the same time, and the cylinder itself rotates, and the first hydraulic cylinder 108 drives the honing head 111 to move back and forth in the cylinder, thereby achieving the purpose of honing multiple cylinders at the same time, greatly improving work efficiency, and being suitable for mass production processing needs. After honing is completed, it is only necessary to release the fixation of the pressure ring 105 through the fixing mechanism 200, and the cylinder can be pulled out from the hollow rotating shaft 102.

[0029] Specifically, the fixing mechanism 200 includes a first guide rod 201 installed on the upper surface of the hollow shaft 102, a first sleeve 207 is installed on the inner wall of the pressure ring 105, and the first sleeve 207 is slidably installed on the outer surface of the first guide rod 201, the outer surface of the first guide rod 201 is provided with a socket 202, the interior of the pressure ring 105 is provided with an inner groove 203, the interior of the inner groove 203 is provided with a plug rod 204, and the end of the plug rod 204 matches the socket 202, the outer surface of the plug rod 204 is provided with a shoulder 205, and the outer surface of the plug rod 204 is sleeved with a first spring 206, the two ends of the first spring 206 respectively abut against the shoulder 205 and the inner wall of the inner groove 203, when the oil cylinder is inserted into the hollow shaft 102, it moves downward By pressing the pressure ring 105, the pressure ring 105 drives multiple second wedge blocks 106 to squeeze multiple first wedge blocks 104 at the same time, and in the process of pressing the pressure ring 105 downward, the end of the insertion rod 204 is driven to slide along the outer surface of the first sliding sleeve 207. When the insertion rod 204 slides to align with the insertion hole 202, under the elastic force of the first spring 206, the insertion rod 204 can be driven to automatically insert into the insertion hole 202, thereby fixing the pressure ring 105. At this time, multiple first wedge blocks 104 are simultaneously pressed against the outer surface of the oil cylinder to achieve the purpose of fixing it in the center. When the insertion rod 204 is pulled outward so that its end is pulled out of the insertion hole 202, the fixation of the pressure ring 105 can be released, making it easy to remove the oil cylinder from the hollow rotating shaft 102.

[0030] Specifically, the driving mechanism 300 includes two side plates 301 installed on the upper surface of the mounting base 101, and a connecting shaft 302 is rotatably connected between the two side plates 301. A plurality of worms 303 are provided on the outer surface of the connecting shaft 302, and a worm wheel 304 is installed on the outer surface of the hollow rotating shaft 102, and the worm wheel 304 is meshed with the worm 303. A motor 305 is installed on the outer surface of one side of the side plates 301, and the output shaft of the motor 305 is connected to the connecting shaft 302. When the motor 305 is started, it drives the connecting shaft 302 to rotate, and then drives the plurality of worms 303 to rotate at the same time. Since the worm 303 and the worm wheel 304 are meshed with each other, the purpose of driving the hollow rotating shaft 102 to rotate is achieved.

[0031] When the first wedge block 104 is squeezed by the second wedge block 106 and moves toward the inner side of the hollow rotating shaft 102, the first wedge block 104 drives the abutment block 402 to compress the second spring 403. Therefore, when the fixing mechanism 200 releases the fixation of the pressure ring 105, the compressed second spring 403 releases the elastic force, thereby pushing the first wedge block 104 to move outward and separating it from the outer surface of the oil cylinder, thereby facilitating the removal of the oil cylinder from the hollow rotating shaft 102.

[0032] Specifically, both sides of the surface of the horizontal plate 109 are provided with a clearance groove 500, and both sides of the lower surface of the U-shaped frame 107 are installed with a second hydraulic cylinder 501, and the second hydraulic cylinder 501 is arranged in the clearance groove 500. The ends of the telescopic ends of the two second hydraulic cylinders 501 are jointly installed with a pressure plate 502, and a plurality of rotating rings 503 are rotatably installed on the surface of the pressure plate 502, and the rotating ring 503, the honing head 111 and the hollow rotating shaft 102 are coaxially arranged. When the cylinder is centered and fixed, the clearance groove 500 is started first, and the clearance groove 500 drives the pressure plate 502 to descend, and presses the rotating ring 503 on the top of the cylinder, which serves the purpose of secondary fixation of the cylinder, thereby ensuring the stability of the cylinder during the honing process and improving the honing quality.

[0033] Specifically, the upper surface of the hollow rotating shaft 102 is connected to the second guide rod 600, and the inner wall of the pressure ring 105 is installed with a second sliding sleeve 601. The second sliding sleeve 601 is slidably installed on the outer surface of the second guide rod 600. Through the setting of the second guide rod 600 and the second sliding sleeve 601, the limiting effect on the pressure ring 105 can be improved, so that it can be raised and lowered smoothly, and ensure that the degree of extrusion of each second wedge block 106 on the first wedge block 104 is consistent.

[0034] Specifically, limiting grooves are provided on the inner walls on both sides of the U-shaped frame 107, and limiting sliders are provided on both sides of the cross plate 109 and the pressure plate 502. The limiting sliders are arranged in the limiting grooves. By setting the limiting grooves and the limiting sliders, the stability of the cross plate 109 and the pressure plate 502 during lifting and lowering can be improved, thereby improving the honing effect.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
