Technical Field
[0001] This utility model relates to the field of automotive parts forging post-processing technology, specifically to a grinding device for tie rod blanks used in automotive parts forging. Background Technology
[0002] Tie rods are critical connecting components in automotive steering and suspension systems, and their quality and precision directly affect a vehicle's handling and safety. During manufacturing, tie rods are typically forged to achieve excellent mechanical properties. However, the forged tie rod blanks often retain irregularities such as oxide scale, burrs, and flash, requiring grinding before subsequent machining and assembly processes. Traditional grinding methods rely heavily on manual labor or simple stationary grinding equipment, resulting in low efficiency, inconsistent grinding quality, high labor intensity for workers, and potential dust hazards. To address these issues, several automated grinding solutions have been proposed in existing technologies.
[0003] For example, a grinding device for automotive shaft parts, with application number CN202322912898.7 and authorization announcement date of 20240813, specifically relates to the field of automotive parts processing technology. It includes a processing table with a protective box on top. An electric slide rail is installed inside the protective box. This invention, through a collection mechanism, can be linked with a motor to continuously drive the fan blades to generate negative pressure suction, thereby drawing debris and dust into the collection frame for filtration and collection, facilitating centralized processing. Simultaneously, it can continuously drive the connecting parts to push and pull the push rod, causing the piston to squeeze water in the pump cylinder, then guiding the water to the spray frame and spraying it out through the nozzle, thereby rinsing and cooling the grinding parts and grinding area, achieving a dust reduction effect and preventing the grinding parts from overheating during prolonged use, thus extending their service life. Through a fixing component, it can be linked with a motor to drive the parts to rotate for grinding at different locations. It is also adaptable to the processing of shaft parts of different diameters and lengths, with a wide range of applications.
[0004] The simple design of the clamping device for automated grinding of transmission cannot flexibly adapt to tie rod blanks of different sizes and shapes, resulting in unstable clamping and easy shaking or displacement of the workpiece during grinding. In addition, traditional grinding devices often have a fixed structure and cannot simultaneously realize the rotation of the workpiece and the multi-directional movement of the grinding head, resulting in incomplete grinding coverage and uneven surface quality. Therefore, it is urgent to design a grinding device for tie rod blanks for automotive parts forging to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a grinding device for tie rod blanks used in automotive parts forging, so as to solve the above-mentioned shortcomings in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A grinding device for forging tie rod blanks of automotive parts includes a base assembly, a clamping assembly, and a grinding assembly. The clamping assembly and the grinding assembly are disposed on top of the base assembly. The clamping assembly includes a right sliding plate and a left sliding plate. A rotating seat one is mounted on one outer wall of the right sliding plate via a bearing, and a rotating seat two is mounted on one outer wall of the left sliding plate via a bearing. Support rods are bolted to one outer wall of both rotating seats one and two, and a limit rod is threadedly fixed to one outer wall of the support rod. A rotating electric... The machine has a rotary motor whose output end is fixedly connected to a rotary seat two via a flat key. The seat assembly includes a base, a sliding groove on one side of the top of the base, and two guide rods installed inside the sliding groove via bolts. A double-acting screw is installed inside the sliding groove via bearings. The right sliding plate and the left sliding plate are slidably mounted on the two guide rods, and the right sliding plate and the left sliding plate are threaded to both ends of the double-acting screw. A drive motor is installed on one side of the outer wall of the base via bolts, and the output end of the drive motor is fixedly connected to one end of the double-acting screw via a coupling.
[0007] Furthermore, a groove is provided on the other side of the top of the base, and two smooth rods are installed inside the groove by bolts. A feed screw is installed between the two sides of the inner wall of the groove by bearings.
[0008] Furthermore, a feed motor is bolted to one side of the outer wall of the base, and the output end of the feed motor is fixedly connected to one end of the feed screw through a coupling.
[0009] Furthermore, the grinding assembly includes a sliding seat, which is slidably mounted on two guide rods and is threadedly connected to the feed screw.
[0010] Furthermore, a support frame is bolted to the center of one side of the top of the sliding seat, and a lifting cylinder is bolted to the center of the top of the support frame.
[0011] Furthermore, a connecting frame is slidably mounted on the support frame, and the output end of the lifting cylinder is fixedly connected to the connecting frame by bolts.
[0012] Furthermore, a grinding motor is bolted to one side of the top of the connecting frame, and a spring telescopic rod is bolted to the output end of the grinding motor, and a grinding wheel is bolted to the output end of the spring telescopic rod.
[0013] Furthermore, the connecting frame has mounting slots on both sides of its top, and two sliding rods are installed in each of the two mounting slots by bolts. A rectangular housing is slidably installed between the two sliding rods in the same mounting slot, and through holes are provided on both sides of the rectangular housing. A placement slot is provided on one side of the top of the connecting frame, and a lead screw motor is installed in the placement slot and one end of the connecting frame by bolts. The lead screw of the lead screw motor extends into the mounting slot, and the lead screw of the lead screw motor is threadedly connected to the rectangular housing.
[0014] In the above technical solution, the present invention provides a grinding device for tie rod blanks used in automotive parts forging, which has the following advantages: This invention uses a drive motor to rotate a bidirectional lead screw, which in turn drives the right and left sliding plates to move synchronously in opposite directions or in opposite directions along the guide rod. This automatically adjusts the distance between the two limit rods, allowing for quick adaptation and stable clamping of pull rod blanks of different lengths. This effectively solves the problems of poor adaptability and unstable clamping of traditional clamps.
[0015] This invention uses a rotary motor to drive the workpiece to rotate at a constant speed around its axis, so that the grinding wheel can evenly cover the entire outer surface of the workpiece, effectively solving the problem of incomplete grinding coverage and improving the grinding quality.
[0016] The grinding assembly of this invention is driven by a feed motor to feed longitudinally along the polishing rod, and the grinding wheel is vertically raised and lowered by a lifting cylinder.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] like Figure 1-4 As shown in the figure, a grinding device for tie rod blanks used in automotive parts forging provided by this utility model includes a base assembly 1, a clamping assembly 2, and a grinding assembly 3. The clamping assembly 2 and the grinding assembly 3 are disposed on the top of the base assembly 1. The clamping assembly 2 includes a right sliding plate 13 and a left sliding plate 14. A rotating seat 15 is mounted on one side of the outer wall of the right sliding plate 13 via a bearing. A rotating seat 2 18 is mounted on one side of the outer wall of the left sliding plate 14 via a bearing. Support rods 16 are bolted to one side of the outer wall of both the rotating seat 15 and the rotating seat 2 18. A limit rod 17 is threadedly fixed to one side of the outer wall of the support rod 16. A limit rod 17 is threadedly fixed to one side of the outer wall of the left sliding plate 14 via a bolt. A rotary motor 19 is fixedly mounted on a bolt, and the output end of the rotary motor 19 is fixedly connected to the rotary seat 18 via a flat key. The seat assembly 1 includes a base 4. A sliding groove 5 is provided on one side of the top of the base 4, and two guide rods 6 are installed inside the sliding groove 5 by bolts. A bidirectional lead screw 7 is installed inside the sliding groove 5 via bearings. A right sliding plate 13 and a left sliding plate 14 are slidably mounted on the two guide rods 6, and the right sliding plate 13 and the left sliding plate 14 are threadedly connected to both ends of the bidirectional lead screw 7. A drive motor 11 is installed on one side of the outer wall of the base 4 by bolts, and the output end of the drive motor 11 is fixedly connected to one end of the bidirectional lead screw 7 via a coupling.
[0025] Specifically, in this embodiment, the assembly includes a base assembly 1, a clamping assembly 2, and a grinding assembly 3. The clamping assembly 2 and the grinding assembly 3 are disposed on the top of the base assembly 1. The clamping assembly 2 includes a right sliding plate 13 and a left sliding plate 14. A rotating seat 15 is mounted on one side of the outer wall of the right sliding plate 13 via a bearing, and a rotating seat 2 18 is mounted on one side of the outer wall of the left sliding plate 14 via a bearing. Support rods 16 are bolted to one side of the outer walls of both rotating seats 15 and rotating seats 2 18, and a limit rod 17 is threadedly fixed to one side of the outer wall of the support rod 16. Rotating seats 15 and rotating seats 2 18 are respectively mounted on the right sliding plate 13 via bearings. The left sliding plate 14 is used to ensure smooth rotation. The support rod 16 is fixed to the rotating seat 15 and the rotating seat 2 18 by bolts. The limiting rod 17 is threaded onto the support rod 16 and is used to hold the end of the blank. By adjusting the position of the limiting rod 17, blanks of different lengths can be adapted to achieve stable clamping. A rotary motor 19 is fixed to the outer wall of one side of the left sliding plate 14 by bolts. The rotary motor 19 is preferably a 60ST-M00630. When the rotary motor 19 is started, its output end is fixedly connected to the rotating seat 2 18 by a flat key, driving the rotating seat 2 18 to rotate. Since the blank is clamped on the rotating seat 15 and the rotating seat 2 18, the blank is held in place by the rotating seat 15 and the rotating seat 2 18. Between the two bases 18, the blank rotates uniformly around the axis, facilitating thorough grinding; and the output end of the rotary motor 19 is fixedly connected to the rotary base 18 via a flat key. The base assembly 1 includes a base 4, with a sliding groove 5 on one side of the top of the base 4. Two guide rods 6 are bolted inside the sliding groove 5, and a bidirectional lead screw 7 is mounted inside the sliding groove 5 via bearings. The right sliding plate 13 and the left sliding plate 14 are slidably mounted on the two guide rods 6, and the right sliding plate 13 and the left sliding plate 14 are threaded to both ends of the bidirectional lead screw 7. A drive motor 11 is bolted to the outer wall of one side of the base 4. The drive motor 11 is superior to... When the 57BYG-250 is selected, and the tie rod blank needs to be clamped, the drive motor 11 is started. Its output end drives the bidirectional lead screw 7 to rotate through the coupling. The two ends of the bidirectional lead screw 7 have opposite threads and are threadedly connected to the right sliding plate 13 and the left sliding plate 14. The right sliding plate 13 and the left sliding plate 14 are slidably mounted on the two guide rods 6. Therefore, the rotation of the bidirectional lead screw 7 drives the right sliding plate 13 and the left sliding plate 14 to move synchronously in opposite directions or in opposite directions along the guide rods 6, thereby adjusting the distance between the rotating seat 15 and the rotating seat 2 18. The output end of the drive motor 11 is fixedly connected to one end of the bidirectional lead screw 7 through the coupling.
[0026] This utility model provides a grinding device for tie rod blanks used in automotive parts forging. The device drives the bidirectional lead screw 7 to rotate via the drive motor 11, which in turn drives the right sliding plate 13 and the left sliding plate 14 to move synchronously towards or away from each other along the guide rod 6. This automatically adjusts the distance between the two limit rods 17, allowing for quick adaptation and stable clamping of tie rod blanks of different lengths. This effectively solves the problems of poor adaptability and unstable clamping of traditional fixtures.
[0027] In one embodiment provided by this utility model, such as Figure 2 As shown, a groove 8 is provided on the other side of the top of the base 4, and two smooth rods 9 are installed inside the groove 8 by bolts. A feed screw 10 is installed between the two sides of the inner wall of the groove 8 by bearings. A feed motor 12 is fixed to the outer wall of one side of the base 4 by bolts. The feed motor 12 is preferably 57BYG-250. When the feed motor 12 is started, its output end drives the feed screw 10 to rotate through the coupling. The sliding seat 20 is threadedly connected to the feed screw 10 and is slidably installed on the two smooth rods 9. Therefore, the rotation of the feed screw 10 drives the sliding seat 20 to move longitudinally along the smooth rod 9, realizing the feed movement of the grinding component 3. The output end of the feed motor 12 is fixedly connected to one end of the feed screw 10 through the coupling.
[0028] In one embodiment provided by this utility model, such as Figure 4As shown, the grinding assembly 3 includes a sliding seat 20, which is slidably mounted on two polishing rods 9. The sliding seat 20 is threadedly connected to the feed screw 10. A support frame 21 is bolted to the center of one side of the top of the sliding seat 20, and a lifting cylinder 22 is bolted to the center of the top of the support frame 21. The lifting cylinder 22 is preferably SC32x100. A connecting frame 23 is slidably mounted on the support frame 21. The lifting cylinder 22 is fixed to the top of the support frame 21 by bolts, and its output end is connected to the connecting frame 23 by bolts, driving the connecting frame 23 to rise and fall, thereby adjusting the height of the grinding wheel 26. The output end of the lifting cylinder 22 is fixedly connected to the connecting frame 23 by bolts. A grinding motor 24 is bolted to one side of the top of the connecting frame 23. The grinding motor 24 is preferably a 775 motor. A spring telescopic rod 25 is bolted to the output end of the grinding motor 24. A grinding wheel 26 is bolted to the output end of the spring telescopic rod 25. When the grinding motor 24 is started, the grinding wheel 26 rotates, and the spring telescopic rod 25 provides constant contact. Pressure is applied to ensure uniform grinding. The connecting frame 23 has mounting slots 28 on both sides of its top, and two sliding rods 30 are bolted into each slot 28. A rectangular housing 29 is slidably mounted between the two sliding rods 30 within the same mounting slot 28, and through holes are provided on both sides of the rectangular housing 29. A placement slot 27 is provided on one side of the top of the connecting frame 23, and a lead screw motor 31 is bolted to one end of the placement slot 27 and the connecting frame 23. The lead screw motor 31 is preferably a 28BYJ-48. To reduce debris splashing, the top of the connecting frame 23 has two mounting slots 28, each... Two sliding rods 30 are bolted into the mounting groove 28. A rectangular housing 29 is slidably mounted on the sliding rods 30 and driven by a lead screw motor 31. The lead screw motor 31 is bolted to one end of the mounting groove 27 and the connecting bracket 23. Its lead screw extends into the mounting groove 28 and is threadedly connected to the rectangular housing 29. When the lead screw motor 31 is started, it drives the two rectangular housings 29 to move closer to each other along the sliding rods 30. After they merge, they cover the grinding wheel 26 and the grinding position of the blank, effectively preventing debris from flying. The lead screw of the lead screw motor 31 extends into the mounting groove 28 and is threadedly connected to the rectangular housing 29.
[0029] Working principle: Before grinding, the tie rod blank is placed between the two limiting rods 17 of the clamping assembly 2. The drive motor 11 is started, and the drive motor 11 drives the bidirectional lead screw 7 to rotate through the coupling. The rotation of the bidirectional lead screw 7 drives the right sliding plate 13 and the left sliding plate 14 to move synchronously towards or away from each other along the guide rod 6, thereby adjusting the distance between the support rods 16 on the first rotating seat 15 and the second rotating seat 18. The limiting rods 17 directly contact both ends of the blank, realizing rapid adaptation and stable clamping of blanks of different lengths. After clamping, the rotary motor 19 is started, and the rotary motor 19 drives the second rotating seat 18 to rotate, thereby driving the blank to rotate at a constant speed around its axis, preparing for full grinding. The grinding assembly 3 is driven by the feed motor 12. After the feed motor 12 is started, it drives the feed lead screw 10 to rotate, driving the sliding seat 20 to move longitudinally along the polishing rod 9. After the lifting cylinder 22 is started, it pushes the connecting frame 23 to rise and fall vertically, thereby adjusting the height position of the grinding wheel 26. After the grinding motor 24 is started, it drives the spring telescopic rod 25 and the grinding wheel 26 to rotate. The spring telescopic rod 25 provides constant contact pressure to ensure that the grinding wheel 26 maintains uniform contact with the surface of the blank. After the lead screw motor 31 is started, it drives the rectangular housing 29 to move horizontally along the slide rod 30, so that the two rectangular housings 29 merge together to cover the grinding wheel 26 and the grinding position of the blank, so that there will be no problem of a large amount of debris flying during grinding. While the blank is clamped and rotated by the clamping assembly 2, the grinding assembly 3 is driven by the feed motor 12 to move along the length of the blank. The vertical position of the grinding wheel 26 is adjusted by the lifting cylinder 22. The grinding wheel 26 performs uniform grinding on the surface of the blank driven by the rotating motor 19, covering the entire circumference. The elastic design of the spring telescopic rod 25 allows the grinding wheel 26 to adapt to the irregular areas of the blank surface, maintain constant pressure, and avoid over-grinding or omission. The whole process realizes comprehensive, efficient and precise grinding of the outer surface of the tie rod blank.
[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
