[0002] The steering gear steel tube is an important component of the automobile steering gear. The steering gear steel tube is in the shape of a long round tube. Before its assembly, it is necessary to open an assembly groove on the circumference of one end of the steering gear steel tube to facilitate the later assembly of the steering gear steel tube.

[0003] The existing method of opening an assembly groove in a steering gear steel pipe is mainly to manually hold an angle grinder in one hand and hold the steering gear steel pipe in the other hand, and grind and cut the assembly groove along the circumference of one end of the steering gear steel pipe. The manual hand-held angle grinder is used for cutting, which is not only time-consuming and labor-intensive, but also has a high labor workload. The efficiency of grinding and cutting the assembly groove is low, and the angle grinder is easy to cut the fingers of the staff during cutting, which poses a certain safety risk. On the other hand, the manual hand-held angle grinder has poor stability when cutting, and the hand-held angle grinder is easy to slip, resulting in a skewed incision, which affects the consistency of the product. Therefore, it is necessary to improve it. Summary of the invention

DETAILED DESCRIPTION

[0019] As attached Figure 1-5 Shown

[0020] The steering gear steel pipe groove milling device comprises a frame 1, a slide plate 2 and a workpiece pushing mechanism. The frame 1 is symmetrically fixedly mounted with a first slide rail 3, the cross section of the first slide rail 3 is in a dovetail shape, an empty groove 4 is arranged on the frame 1 between the first slide rails 3, a transmission screw rod 5 is movably mounted in the empty groove 4 through a bearing, one end of the transmission screw rod 5 extends to the outside of the frame 1, and a hand wheel 6 is mounted on the transmission screw rod 5 extending to the outside of the frame 1. When working, the transmission screw rod 5 can be driven to rotate forward or reverse by rotating the hand wheel 6.

[0021] A slide plate 2 is slidably installed on the slide rail, and a dovetail groove is provided at the corresponding position of the slide plate 2 and the first slide rail 3. The dovetail groove of the slide plate 2 is slidably connected with the first slide rail 3. The slide plate 2 is a rectangular plate, and a connecting block 7 is fixedly installed at the corresponding position of the slide plate 2 and the empty slot 4. The connecting block 7 extends into the empty slot 4, and an assembly hole is provided on the connecting block 7 extending into the empty slot 4. A lead screw nut is fixedly installed in the assembly hole, and the lead screw nut is threadedly connected with the transmission screw 5. During operation, when the transmission screw 5 rotates forward or reversely, under the limiting action of the lead screw nut, the slide plate 2 can slide left or right along the axial direction of the transmission screw 5.

[0022] The slide plate 2 is provided with a workpiece pushing mechanism, which includes a fixed seat 8, a base plate 9 and a pushing plate 10. The fixed seat 8 is fixedly mounted on the slide plate 2, and a base plate 9 is fixedly mounted on the slide plate 2 on one side of the fixed seat 8. A second slide rail 11 is symmetrically arranged on the base plate 9. The cross-section of the second slide rail 11 is in a dovetail shape. The pushing plate 10 is slidably mounted on the second slide rail 11. Dovetail grooves are arranged at corresponding positions of the pushing plate 10 and the second slide rail 11. The dovetail groove of the pushing plate 10 is slidably connected with the second slide rail 11. When working, the pushing plate 10 can slide along the axial direction of the second slide rail 11.

[0023] A rotating shaft 12 is movably inserted on the top of the fixed seat 8 through a bearing, and a gear 13 is fixedly installed on the rotating shaft 12. A rack 14 is fixedly installed on one side edge of the pushing plate 10 corresponding to the gear 13. The gear 13 and the rack 14 are meshed and connected. During operation, when the gear 13 rotates, the rack 14 and the pushing plate 10 are driven to slide along the axial direction of the slide rail under the cooperation of the gear 13 and the rack 14.

[0024] A push rod 15 is arranged on the circumference of the gear 13 , and the purpose of such arrangement is to facilitate the staff to drive the gear 13 to rotate through the push rod 15 .

[0025] A limit rod 16 is provided on the circumference of the gear 13 on one side of the push rod 15, and a stop rod 17 is installed on the slide plate 2 on one side of the gear 13. The stop rod 17 is intermittently contacted and connected with the limit rod 16. When working, the stop rod is used to limit the limit rod 16, thereby limiting the gear 13 through the limit rod 16, so that after the gear 13 rotates into place, it stops rotating immediately due to the restriction of the limit rod 16.

[0026] A workpiece fixing mechanism is installed on the workpiece pushing mechanism, and the workpiece fixing mechanism includes an assembly seat 18 and a screw 19. The cross-section of the assembly seat 18 is in a "concave" shape. A tightening plate 20 is arranged in the groove of the assembly seat 18. The tightening plate 20 is a rectangular plate. The bottom end of the tightening plate 20 is connected in sliding contact with the inner bottom surface of the groove of the assembly seat 18. A threaded hole is arranged on the assembly seat 18 on one side of the tightening plate 20. The screw 19 is threadedly inserted in the threaded hole. A movable seat 22 is movably installed at one end of the screw 19. The movable seat 22 is fixedly connected to the tightening plate 20. A rotating drum 21 is fixedly installed at the other end of the screw 19. When working, the staff can drive the screw 19 to rotate through the rotating drum 21.

[0027] An assembly plate 23 is fixedly mounted on the frame 1 at one end of the slide rail, and a grinding and cutting mechanism is mounted on the assembly plate 23. The grinding and cutting mechanism includes a drive motor 24 and a slot milling blade 28. The drive motor 24 is fixedly mounted on the assembly plate 23. A fixing bar 26 is fixedly mounted on the assembly plate 23 on one side of the drive motor 24. A shaft rod 27 is movably mounted on the fixing bar 26. A slot milling blade 28 is fixedly mounted on one end of the shaft rod 27. The slot milling blade 28 is arranged corresponding to the push plate 10.

[0028] A driven pulley 30 is fixedly mounted on the other end of the shaft 27 , and a driving pulley 29 is fixedly mounted on the transmission shaft of the driving motor 24 corresponding to the driven pulley 30 . The driving pulley 29 and the driven pulley 30 are connected via a transmission belt 25 .

[0029] When the groove milling device is used, first, one end of the steering gear steel pipe 31 to be processed is placed between the top clamping plate 20 and the groove side wall of the assembly seat 18, and then the rotating drum 21 is rotated, and the rotating drum 21 drives the screw 19 to rotate. Under the cooperation of the screw 19 and the threaded hole of the assembly seat 18, the screw 19 pushes the top clamping plate 20 to move closer to the groove side wall of the assembly seat 18, thereby clamping the steering gear steel pipe 31 under the cooperation of the top clamping plate 20 and the groove side wall of the assembly seat 18.

[0030] After the steering gear steel tube 31 is clamped, the transmission screw 5 is driven to rotate through the hand wheel 6, and the transmission screw 5 drives the slide plate 2 to slide along the axial direction of the first slide rail 3, so that the steering gear steel tube 31 corresponds to the groove milling blade 28. After the correspondence is completed, the drive motor 24 is started, and the drive motor 24 drives the active pulley 29 to rotate. Under the transmission action of the transmission belt 25, the active pulley 29 drives the driven pulley 30 to rotate, and the driven pulley 30 drives the groove milling blade 28 to rotate synchronously through the shaft 27.

[0031] At this time, the staff drives the gear 13 to rotate through the push rod 15. When the gear 13 rotates, with the cooperation of the gear 13 and the rack 14, the rack 14 and the push plate 10 are driven to slide toward the milling blade 28 along the axial direction of the slide rail until the steering gear steel pipe 31 contacts the milling blade 28, and the milling operation can be started. Until the stop rod 17 on the gear 13 contacts the limit rod 16, the stop rod forms a limit on the limit rod 16, thereby limiting the gear 13 through the limit rod 16, so that the gear 13 stops rotating immediately. At this time, the milling blade 28 completes the operation of milling the assembly groove 32 on one end of the steering gear steel pipe 31, and the gear 13 is reset by the push rod 15, and the steering gear steel pipe 31 with the assembly groove 32 milled is removed, thereby completing the milling operation of the steering gear steel pipe 31, replacing the next steering gear steel pipe 31 to be processed, and the milling operation of the steering gear steel pipe 31 can be repeated.

[0032] The steering gear steel pipe groove milling device drives the slide plate 2 to slide along the first slide rail 3 through the cooperation of the slide plate 2, the first slide rail 3, the transmission screw 5 and the hand wheel 6, thereby adjusting the relative positions of the workpiece pushing mechanism and the workpiece fixing mechanism on the slide plate 2 and the groove milling blade 28, so as to facilitate the correspondence between the groove milling blade 28 and the steering gear steel pipe 31. The assembly seat 18, the screw 19 and the top plate 20 of the workpiece fixing mechanism cooperate with each other to achieve the clamping of the steering gear steel pipe 31. The push rod 15, the fixing seat 8, the base plate 9 and the pushing plate 10 of the workpiece pushing mechanism drive the workpiece fixing mechanism and the steering gear steel pipe 31 to move toward the groove milling blade 28, thereby starting the groove milling operation. The groove milling device effectively reduces manual labor, improves grinding and cutting efficiency, and avoids the problem of incision deviation and affecting product consistency.
