[0002] Car tie rods, such as Figure 1 The image shows a crucial component for automotive steering. It has internal threads at both ends and connects to the tie rod assembly. It is secured using a clamp with an open slot, and the clamp has a locking screw. The R-slot on the tie rod is designed to prevent the locking screw from rotating and to facilitate assembly and locking.

[0003] In the process of realizing this utility model, the inventors discovered that:

[0004] In actual manufacturing, the R-groove on the tie rod is generally machined using an end mill, which is inefficient due to single-piece production. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, this utility model provides a processing device for R-groove of horizontal tie rod in a fast vertical drilling machine.

[0006] Inventive concept: Consider placing two horizontal tie rods side by side, as... Figure 2 As shown, a partition is added and fixed in the middle, which can be directly processed with a drill bit. Two parts can be processed at the same time with one drill bit, and the two ends can be processed separately or both ends can be processed at the same time by moving left and right.

[0007] Therefore, the technical solution of this utility model is: a processing device for a rapid vertical drilling horizontal tie rod R-groove, comprising a worktable and a bench drill, wherein the bench drill is fixed on the worktable, characterized in that: two bench drills are provided, mirror-symmetrically arranged on both sides of the worktable.

[0008] Each base located below the bench drill has a base plate. On the outer side of the opposite base plate is a positioning seat. On the outer wall of the positioning seat is a slidingly fitted pull block. A slidingly fitted pull rod passes through the pull block. The pull rod extends through the positioning seat towards the other side of the bench drill and is threaded to the end of the rod. The pull block and the positioning block can slide up and down along the positioning seat and are fastened to the positioning seat by the pull rod. The front end of the positioning block has a horizontal positioning plate that matches the opening slot of the horizontal pull rod. The horizontal positioning plate is inserted into the opening slots of the two horizontal pull rods. The horizontal positioning plate has a clearance cavity. On the inner side of the opposite base plate is a middle positioning block. The middle positioning block has an inverted T-shaped structure. The two sides of its vertical plate cooperate with the horizontal section to form the support surface of the two horizontal pull rods to be processed.

[0009] Cylinders are provided on the front and rear sides of the base plate, and top blocks are provided at the piston rod ends of the cylinders. The top blocks are directly opposite the center of the right angle between the two sides of the middle positioning block.

[0010] The T-shaped right-angled surfaces of the top block and the middle positioning block together form the clamping part of the outer circumference of the tie rod, and the horizontal positioning plate forms the limiting part that restricts the circumferential rotation of the tie rod.

[0011] Preferably, the positioning seat has a through square groove, and the pull rod passes through one end of the groove via a pull block. The positioning block has a protrusion on the side near the positioning seat, which slides up and down within the groove. The protrusion has a threaded hole for connecting the pull rod. This design accommodates horizontal pull rods of different pipe diameters, facilitating adjustment of the height of the horizontal positioning plate.

[0012] Preferably, the vertical projection of the drill bit of the bench drill is located at the vertical section of the intermediate positioning block, where a clearance groove is provided. This avoids interference when the drill bit moves downward.

[0013] Preferably, the base plate is provided with a bracket, the bracket is provided with a cylinder support seat, and the cylinder is provided with the cylinder support seat to ensure the installation angle of the cylinder.

[0014] Preferably, the positioning seat is further provided with a drill template, and a drill die sleeve is provided on the drill template at a position corresponding to the drill bit, to ensure that the workpiece is drilled in the correct position.

[0015] Beneficial effects: This utility model can place two workpieces side by side on both sides of the middle positioning block of the inverted T-shaped structure. The horizontal positioning plate is simultaneously inserted into the opening slots of the two horizontal tie rods to effectively prevent rotation. Then, it is clamped and fixed by a cylinder. Thus, two workpieces can be processed at the same time using a drill bit, which improves efficiency and is suitable for mass production. Moreover, processing two parallel rods results in more uniform force distribution than processing a single rod, saving tools and reducing costs. Attached Figure Description

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings, but this embodiment should not be construed as a limitation of this utility model.

[0027] This utility model is as follows Figures 3 to 9 As shown:

[0028] A machining device for a rapid vertical drill horizontal tie rod R-groove includes a worktable 1 and a bench drill 2. The bench drill is fixed on the worktable, and two bench drills are provided, mirror-symmetrically arranged on both sides of the worktable.

[0029] Each base located below the bench drill is equipped with a base plate 3. On the opposite outer side of the base plate, there is a positioning seat 4. On the outer wall of the positioning seat, there is a slidingly fitted pull block 5. A slidingly fitted pull rod 6 passes through the pull block. The pull rod passes through the positioning seat and extends towards the other side of the bench drill. The end is threaded with a positioning block 7. The pull block and the positioning block can slide up and down along the positioning seat and are fastened to the positioning seat 4 by the pull rod. The front end of the positioning block 7 extends out with a horizontal positioning plate 71 that is adapted to the opening slot of the horizontal pull rod. The horizontal positioning plate is simultaneously inserted into the opening slot F of the two horizontal pull rods N. The horizontal positioning plate has a clearance cavity 72. On the inner side of the opposite base plate 3, there is a middle positioning block 8. The middle positioning block has an inverted T-shaped structure. The two sides of its vertical plate cooperate with the horizontal section to form the support surface of the two horizontal pull rods to be processed.

[0030] Cylinders 9 are provided on the front and rear sides of the base plate 3 respectively. The piston rod end of the cylinder is provided with a top block 10, which is directly opposite the center of the right angle between the two sides of the middle positioning block.

[0031] The T-shaped right-angled surfaces of the top block 10 and the middle positioning block 8 together form the clamping part of the outer circumference of the horizontal tie rod, and the horizontal positioning plate 71 forms the limiting part that restricts the circumferential rotation of the horizontal tie rod.

[0032] In this embodiment, the positioning seat 4 has a through square groove 41. The pull rod 6 passes through one end of the groove via a pull block. The positioning block 7 has a protrusion 73 on the side near the positioning seat. The protrusion slides up and down in the groove and has a threaded hole for connecting the pull rod 6. The pull block 5 has a protrusion on the side near the positioning seat and slides in the groove via the protrusion. The purpose is to accommodate horizontal pull rods of different pipe diameters and facilitate the adjustment of the height of the horizontal positioning plate.

[0033] In this embodiment, the vertical projection of the drill bit of the bench drill is located at the vertical section of the intermediate positioning block 8, where an avoidance groove 81 is provided. This avoids interference when the drill bit moves downward.

[0034] In this embodiment, a bracket 11 is provided on the base plate 3, a cylinder support seat 12 is provided on the bracket, and a cylinder 9 is provided on the cylinder support seat to ensure the installation angle of the cylinder.

[0035] In this embodiment, the positioning seat is also provided with a drill template 13, and a drill die sleeve 14 is provided on the drill template at a position corresponding to the drill bit. This ensures that the workpiece is drilled in the correct position.

[0036] The working principle of this utility model:

[0037] When the distance between the two positioning blocks is greater than the length of the horizontal tie rod, and the horizontal tie rod can be placed directly, first adjust the required drill bit to align with the drill jig sleeve. The drill bit can rotate freely inside the drill sleeve. Place the two horizontal tie rods on the middle positioning block 7 respectively. Move the horizontal tie rod to the left so that its opening slot is aligned with the horizontal positioning plate and locked onto the positioning block. Open the cylinder to clamp and hold the tie rod in place, and you can start drilling simultaneously. After the left side is processed, release the cylinder, and move the two horizontal tie rods to the right so that the opening of the other end of the horizontal tie rod is locked onto the positioning block. Use the cylinder on the other side to clamp and hold the tie rod in place, and start drilling on the right side. In this case, it is convenient to place and remove the horizontal tie rod. The disadvantage is that the two ends cannot be processed simultaneously.

[0038] When the spacing between the positioning blocks on both sides is adapted to the length of the horizontal tie rod, the horizontal tie rod can only be placed and removed in the front and back direction. It is necessary to ensure alignment and even force on both sides. However, the advantage is that it can achieve synchronous processing on both sides and does not require major changes to the equipment.

[0039] It should be noted that, based on the above technical solution, one side of the base plate can be set as a conventional structure that can move left and right and be fixed in place. This eliminates the need to move the horizontal tie rod left and right. Instead, one side of the base plate can be moved, clamped, and fixed to achieve simultaneous processing on both sides, further improving efficiency.

[0040] Any aspects not described in detail in this specification are techniques well-known in the art.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
