Description

Technical Field

[0001] This utility model relates to the field of machine tool accessory technology, specifically a single-sided adjustable center rest. Background Technology

[0002] In machine tool processing, such as on a deep hole drilling and boring machine, when clamping the workpiece, a triangular center rest is usually used to clamp the workpiece. For example, a machine tool processing center rest disclosed in CN208811556U has three clamping mechanisms set in the triangular position of the center rest to clamp the workpiece in the center. When adjustment is required, personnel need to move to different positions where the clamping mechanisms are located to make adjustments, which means they need to go over the machine tool. The adjustment process is cumbersome and poses certain safety risks. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 like Figures 1-3 As shown, the single-sided adjustable center frame in this embodiment is used in conjunction with a machine tool, mainly for clamping workpieces and adjusting the clamping position. It mainly consists of a main frame body 10, a first claw body 20 rotatably disposed at the lower part of the main frame body 10, a first adjustment component 50 disposed at the end of the first claw body 20, a second claw body 30 rotatably disposed at the top of the main frame body 10, a second adjustment component 60 disposed at the end of the second claw body 30, a third claw body 40 movably disposed in the middle of the main frame body 10, and a third adjustment component 70 disposed at the end of the third claw body 40. The first adjustment component 50 can adjust the height and drive the first claw body 20 to rotate, the second adjustment component 60 can adjust the height and drive the second claw body 30 to rotate, and the third adjustment component 70 is used to drive the third claw body 40 to make a horizontal linear movement. The workpiece is thus adjustablely clamped between the first claw body 20, the second claw body 30, and the third claw body 40.

[0019] A base 90 is provided below the main frame 10 for support. The main frame 10 is roughly C-shaped. The first claw 20, the second claw 30 and the third claw 40 are all located on the same side of the main frame 10 at the end that mates with the workpiece.

[0020] Specifically, both the first adjustment component 50 and the second adjustment component 60 include an adjustment body 51 and an adjustment plate 52. The adjustment body 51 and the adjustment plate 52 are threadedly connected to form a nut-screw structure. The adjustment plate 52 is located on one side of the main frame 10. The adjustment body 51 is slidably engaged with the first claw body 20 and the second claw body 30. The ends of the first claw body 20 and the second claw body 30 are provided with inwardly recessed grooves 21. The end of the adjustment body 51 is inserted into the groove 21 and can slide within the groove 21. The groove 21 can be semi-circular, while the end of the adjustment body 51 can be machined into a spherical shape. The sliding of the two together can reduce friction. Thus, by rotating the adjustment body 51, its linear displacement can be achieved, thereby driving the first claw body 20 and the second claw body 30 to rotate.

[0021] Correspondingly, the top and bottom of the main frame 10 are provided with clearance holes 11, which allow the first claw body 20 and the second claw body 30 to rotate.

[0022] Furthermore, the third adjustment component 70 includes a rotating body 71 and a linkage 72. The rotating body 71 is restricted to one side of the main frame 10 and can only rotate. One end of the linkage 72 passes through the rotating body 71 and is threadedly engaged with the rotating body 71. The other end of the linkage 72 is connected to the third claw body 40. The linkage 72 is restricted within the main frame 10 and can only make linear displacement. The rotating body 71 is provided with a rotating handle 73. Applying force to the rotating handle 73 can drive the rotating body 71 to rotate. By holding the rotating handle 73, the rotating body 71 is driven to rotate. The linkage 72 is restricted to linear motion by the main frame 10 under the drive of the rotating body 71, and then drives the third claw body 40 to move.

[0023] In order to achieve the in-situ rotation of the rotating body 71, the main frame 10 is provided with a mounting groove, which is used to accommodate part of the rotating body 71. The mounting groove is covered with a limiting plate 13, which covers part of the rotating body 71. The rotating body 71 is restricted to a fixed position by the cooperation between the mounting groove and the limiting plate 13.

[0024] Furthermore, a through hole 12 is provided in the middle of the main frame 10, and the third claw body 40 and the linkage body 72 can move linearly within the through hole 12, and can only move linearly.

[0025] Of course, rollers 80 are rotatably connected to the ends of the first claw body 20, the second claw body 30, and the third claw body 40, and the rollers 80 contact and cooperate with the workpiece.

[0026] Here, the first claw body 20 and the second claw body 30 are rotatably connected to the main frame body 10 through the pin 101, and are generally V-shaped to facilitate rotational movement.

[0027] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
