Abstract
Description
Technical Field
[0001] This utility model relates to the field of workpiece positioning technology, and in particular to a workpiece anti-floating positioning device. Background Technology
[0002] In the field of machining, especially when milling, drilling, and tapping lightweight or less rigid materials such as aluminum alloys and composite materials, the workpiece is prone to running, shaking, or even floating away from the positioning reference due to the influence of cutting forces, vibrations, and cutting fluid impacts. This type of "floating" problem not only significantly reduces machining accuracy, leading to workpiece dimensional deviations and loss of form and position tolerances, but may also cause machining failure or even part scrap.
[0003] Currently, the most common workpiece clamping methods used in the industry include mechanical vises and vacuum chucks. While mechanical vises offer high clamping reliability, their clamping force is mainly concentrated on the sides of the jaws, providing weak rigid support for the central area of the workpiece. When machining the central area, the cutting force can easily cause elastic deformation or localized lifting of the workpiece, affecting machining consistency. Vacuum chucks rely on sealing and suction force to fix the workpiece, but for workpieces with rough surfaces, complex geometries, or those requiring through-hole machining, effective sealing often fails to achieve a proper seal, resulting in a loss of suction force and limited positioning capability. Utility Model Content
[0004] Based on this, the present invention provides a workpiece anti-floating positioning device with a simple structure and convenient use. Through the synergistic action of the X-axis positioning block and X-axis pressure head, the Y-axis fixed clamping block and Y-axis moving clamping block, and the Z-axis pressure block, the workpiece is clamped in three axial directions, effectively preventing the workpiece from floating and greatly improving clamping accuracy and processing quality.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0014] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0016] Please see Figures 1 to 6 The workpiece anti-floating positioning device according to one embodiment of the present utility model includes a worktable 10, an X-axis positioning component 20 installed on the top surface of the worktable 10, and a Y-axis positioning component 30 and a Z-axis positioning component 40 installed on one side of the bearing component 10.
[0017] The workbench 10 is provided with two through holes 11 spaced apart. Support blocks 12 are connected to the outer side of each through hole 11 on the top surface of the workbench 10. The two support blocks 12 are used to support the workpiece 50.
[0018] The X-axis positioning assembly 20 includes an X-axis positioning block 21 installed on the outside of one support block 12 and an X-axis pressure head 22 movably installed on the outside of another support block 12; the X-axis positioning block 21 and the X-axis pressure head 22 are arranged opposite to each other.
[0019] In this embodiment, the X-axis indenter 22 is connected to the worktable 10 via an X-axis push-pull cylinder 23 to achieve movable installation of the X-axis indenter 22. After the workpiece is placed in position, the X-axis push-pull cylinder 23 drives the X-axis indenter 22 to abut against the workpiece 50, thereby clamping the workpiece 50 in the X-axis direction. Figure 1 and Figure 2 As shown.
[0020] The Y-axis positioning assembly 30 includes a Y-axis fixed clamping block 31 fixedly installed at one end of each through hole 11, a Y-axis movable clamping block 32 opposite to the Y-axis fixed clamping block 31, connecting rods 33 connecting each Y-axis movable clamping block 32, Y-axis push-pull cylinders 34 hinged to each connecting rod 33, two cantilever arms 35 parallelly and spaced apart from the worktable 10, and a support rod 36 connected to the ends of the two cantilever arms 35; the support rod 36 is used to connect the Y-axis push-pull cylinder 34. The workpiece 50 is located between the Y-axis fixed clamping block 31 and the Y-axis movable clamping block 32. The Y-axis push-pull cylinder 34 drives the Y-axis movable clamping block 32 closer to the Y-axis fixed clamping block 31 to clamp the workpiece 50 in the Y-axis direction. Figure 1 and Figure 2 As shown.
[0021] Specifically, such as Figure 2 and Figure 6 As shown, the connecting rod 33 passes through the through hole 11. The middle part of the connecting rod 33 is used to hinge the worktable 10. The top of the connecting rod 33 is connected to the Y-axis movable clamping block 32. The bottom end of the connecting rod 33 is hinged to the piston rod of the Y-axis push-pull cylinder 34, and the cylinder of the Y-axis push-pull cylinder 34 is hinged to the support rod 36.
[0022] The Z-axis positioning assembly 40 includes a base 41 fixedly connected to one side of the worktable 10, a lifting cylinder 42 mounted on the base 41, and a Z-axis pressing block 43 connected to the piston rod of the lifting cylinder 42; the Z-axis pressing block 43 is used to abut against the workpiece 50.
[0023] Specifically, such as Figure 1 As shown, the workpiece 50 has a through hole 51 in the middle, and the Z-axis pressure block 43 is used to clamp the workpiece 50 after being inserted into the through hole 51.
[0024] Furthermore, in this embodiment, the Z-axis pressure block 43 is located between two Y-axis fixed clamping blocks 31, and the lifting cylinder 42 is located between two Y-axis push-pull cylinders 34.
[0025] The above-mentioned workpiece anti-floating positioning device has a simple structure and is easy to use. Through the coordinated action of the X-axis positioning block 21 and the X-axis pressure head 22, the Y-axis fixed clamping block 31 and the Y-axis moving clamping block 32, and the Z-axis pressure block 43, the workpiece 50 is clamped in three axial directions, which effectively prevents the workpiece 50 from floating and greatly improves the clamping accuracy and processing quality.
[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
