[0001] The utility model relates to the technical field of processing tooling, in particular to a processing tooling for a steering tie rod arm. Background Technique

[0002] The steering tie rod is an important part in the automobile steering mechanism, which directly affects the steering stability, running safety and tire service life of the automobile. The steering tie rod is divided into two categories, namely the steering straight tie rod and the steering cross tie rod. The steering straight tie rod undertakes the task of transmitting the movement of the steering rocker arm to the steering knuckle arm; the steering cross tie rod is the bottom edge of the steering trapezoid mechanism and is a key component to ensure the correct movement relationship of the left and right steering wheels. During the production and processing of the steering tie rod arm, it needs to be fixed by processing tooling to facilitate subsequent processing.

[0003] However, during the use of the existing processing tooling, different sizes of steering tie rod arms require different models of processing tooling to be designed, and it is not easy for the processing tooling to stably clamp and fix different sizes of steering tie rod arms. Therefore, those skilled in the art provide a processing tooling for a steering tie rod arm to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to provide a processing tooling for a steering tie rod arm to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0007] The fixing mechanism includes a cast iron fixing block, a first clamping frame is fixed on one side of the cast iron fixing block, a guiding frame is fixed on one side of the cast iron fixing block, a moving mounting block is movably sleeved on the outside of the guiding frame, a second clamping frame is fixed on the side of the moving mounting block close to the first clamping frame, a mounting connection head is embedded and fixed on one side of the moving mounting block, a threaded fixing block is installed on the top of the second metal block, an internal thread is opened inside the threaded fixing block, and a self-locking threaded rod passing through the other side of the threaded fixing block is threadedly connected to one side of the threaded fixing block, and a handle frame is fixed at the end of the self-locking threaded rod away from the mounting connection head.

[0008] As a further solution of the utility model: The stabilizing mechanism includes a fixed outer shell, a support spring is fixed on the inner bottom wall of the fixed outer shell, a low-carbon steel block is arranged on the top of the support spring, a plastic plate is fixed on one side of the low-carbon steel block, a support frame is installed on the top of the low-carbon steel block, a rubber anti-slip sleeve is fixed on the top of the support frame, and a roller sleeve is fixed at one end of the low-carbon steel block.

[0009] As a further solution of the utility model: A limit roller is rotatably connected inside the roller sleeve through a rotating shaft, and a through groove for the plastic plate to move is opened inside the fixed outer shell.

[0010] As a further solution of the utility model: The fixed outer shell is fixedly connected to the second metal block, and a through hole for the support frame to move is opened inside the fixed outer shell.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The device is provided with a fixing mechanism. When machining and positioning the steering tie rod arm, one end of the steering tie rod arm can be inserted between the first clamping frame and the second clamping frame. After the handle frame rotates, it drives the self-locking threaded rod to rotate. When the self-locking threaded rod is used, the threaded fixing block is provided with an internal thread, and a 30° bevel is opened at the root of the internal thread of the threaded fixing block, and its pitch diameter is increased compared with the ordinary thread. When the self-locking threaded rod is screwed into the threaded fixing block, the top of the external thread of the self-locking threaded rod will contact the 30° bevel at the root of the internal thread of the threaded fixing block to generate a clamping force. This contact is carried out along the helix on the entire length of the thread. Therefore, it has a good centering effect, keeps the bolt and the threaded hole in good concentricity, and makes the threads not generate relative lateral movement. Therefore, it will not be loosened under vibration and lateral load, thus ensuring the stable clamping and fixing of the steering tie rod arm. By stably clamping the outside of the steering tie rod arm through the second clamping frame and the first clamping frame, the steering tie rod arm of different sizes can be stably clamped and fixed, which is beneficial to the machining of the steering tie rod arm;

[0015] 2. The device is provided with a stabilizing mechanism. When it is not necessary to rotate the handle frame and the self-locking threaded rod, the plastic plate can be loosened, and the low-carbon steel block is pushed upward by the support spring inside the fixed housing. The support frame drives the upper surface of the rubber anti-slip sleeve to fit against the outside of the self-locking threaded rod, thereby completing the bottom reinforcement of the self-locking threaded rod and playing an auxiliary reinforcement role.

[0022] The fixing mechanism 6 includes a cast iron fixing block 61. One side of the cast iron fixing block 61 is fixed with a first clamping frame 62, and one side of the cast iron fixing block 61 is fixed with a guide frame 63. A movable mounting block 64 is movably sleeved on the outer side of the guide frame 63. One side of the movable mounting block 64 close to the first clamping frame 62 is fixed with a second clamping frame 65. One side of the movable mounting block 64 is embedded and fixed with a mounting connector 66. A threaded fixing block 69 is mounted on the top of the second metal block 5. An internal thread is provided inside the threaded fixing block 69. One side of the threaded fixing block 69 is threadedly connected with a self-locking threaded rod 67 passing through the other side thereof. Anti-slip threads are provided on the inner walls of both the first clamping frame 62 and the second clamping frame 65. The self-locking threaded rod 67 and the mounting connector 66 are connected by a bearing. One end of the self-locking threaded rod 67 away from the mounting connector 66 is fixed with a handle frame 68. A 30° bevel is provided at the root of the internal thread of the threaded fixing block 69. The cast iron fixing block 61 and the first metal block 4 are fixedly connected.

[0023] As an implementation mode of the present utility model, the stabilizing mechanism 7 includes a fixed housing 71. A support spring 72 is fixed on the inner bottom wall of the fixed housing 71. A low-carbon steel block 73 is arranged on the top of the support spring 72. One side of the low-carbon steel block 73 is fixed with a plastic plate 74. A support frame 75 is mounted on the top of the low-carbon steel block 73. The fixed housing 71 and the second metal block 5 are fixedly connected. A through hole for the support frame 75 to move is provided inside the fixed housing 71. A rubber anti-slip sleeve 76 is fixed on the top of the support frame 75. One end of the low-carbon steel block 73 is fixed with a roller sleeve 77. A limiting roller 78 is rotatably connected inside the roller sleeve 77 through a rotating shaft. A through groove for the plastic plate 74 to move is provided inside the fixed housing 71.

[0024] The working principle of the present utility model is as follows: The device is provided with a fixing mechanism 6. When machining and positioning the steering tie rod arm, one end of the steering tie rod arm can be inserted between the first clamping frame 62 and the second clamping frame 65. At this time, the inner bottom wall of the first clamping frame 62 limits and supports one end of the steering tie rod arm. Then the user holds the handle frame 68 and rotates the handle frame 68. After the handle frame 68 rotates, it drives the self-locking threaded rod 67 to rotate. The self-locking threaded rod 67 is threadedly connected with the threaded fixing block 69, and the self-locking threaded rod 67 and the mounting connector 66 are connected through a bearing. As the self-locking threaded rod 67 rotates, it can drive the mounting connector 66 and the moving mounting block 64 to move horizontally. The moving mounting block 64 can move outside the guiding frame 63, playing a role in limiting. The second clamping frame 65 can clamp the outside of the steering tie rod arm. When the self-locking threaded rod 67 is in use, the threaded fixing block 69 is provided with internal threads, and a 30° bevel is provided at the root of the internal threads of the threaded fixing block 69, and its pitch diameter is increased compared with ordinary threads. When the self-locking threaded rod 67 is screwed into the threaded fixing block 69, the top of the external threads of the self-locking threaded rod 67 will contact the 30° bevel at the root of the internal threads of the threaded fixing block 69 to generate a clamping force. This contact is carried out along the helix over the entire length of the thread. Therefore, it has a good centering effect, maintains good concentricity between the bolt and the threaded hole, and prevents relative lateral movement between the threads. Therefore, it will not be loosened under vibration and lateral loads, thus ensuring stable clamping and fixing of the steering tie rod arm. The outside of the steering tie rod arm is stably clamped by the second clamping frame 65 and the first clamping frame 62, and the steering tie rod arm with different sizes can be stably clamped and fixed, which is beneficial to the machining of the steering tie rod arm; The device is provided with a stabilizing mechanism 7. When the user holds the handle frame 68 and rotates the handle frame 68, it is necessary to press down the plastic plate 74. The plastic plate 74 drives the low-carbon steel block 73 and the support frame 75 to move, avoiding the rubber anti-slip sleeve 76 on the top of the support frame 75 from affecting the normal rotation of the self-locking threaded rod 67. When the second clamping frame 65 and the first clamping frame 62 clamp the steering tie rod arm and there is no need to rotate the handle frame 68 and the self-locking threaded rod 67, the plastic plate 74 can be released. The support spring 72 in the fixed housing 71 pushes the low-carbon steel block 73 upward, and the support frame 75 drives the upper surface of the rubber anti-slip sleeve 76 to fit against the outside of the self-locking threaded rod 67, thus completing the bottom reinforcement of the self-locking threaded rod 67, playing an auxiliary reinforcement role.

[0025] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
