[0002] A fixture is a tool for fixing the workpiece to be processed to prevent the workpiece from shaking during the processing, thereby improving the processing accuracy of the workpiece. In traditional technology, the workpiece is generally clamped by a vise. Since the vise pushes the workpiece to resist the fixed surface, the workpiece is fixed by clamping the opposite surface of the workpiece, that is, the installation position of one side of the workpiece can be calculated through the fixed surface that the workpiece resists. However, when the workpiece is fixed by a vise, only the installation position of one side of the workpiece can be determined after the workpiece is fixed. For the position of the adjacent surfaces of the workpiece, the tool position of the workpiece needs to be confirmed by tool setting, which increases the time for confirming the tool position before processing the workpiece, and increases the overall processing time of the workpiece.

[0032] like Figure 1 As shown, it is a quick positioning fixture 100 shown in the present invention.

[0033] like Figure 1As shown, the rapid positioning fixture 100 includes: a base 10, a positioning frame 20, a guide frame 30, an auxiliary positioning assembly 40 and a clamping positioning assembly 50, wherein the base 10 is used to install the positioning frame 20 and the guide frame 30, the positioning frame 20 and the guide frame 30 are spaced to form a limiting space 60 for placing the workpiece, the auxiliary positioning assembly 40 pushes the workpiece to abut against the positioning frame 20 along the first direction F1, and the clamping positioning assembly 50 pushes the workpiece to abut against the positioning frame 20 along the second direction F2 to achieve positioning of the workpiece, the first direction F1 and the second direction F2 are arranged perpendicular to each other, and the initial position of the workpiece can be effectively calculated through the surface of the positioning frame 20 abutting against the workpiece along the first direction F1 and the second direction F2, thereby reducing the time for confirming the tool position point, reducing the overall processing time of the workpiece, and achieving the purpose of improving the processing efficiency of the workpiece.

[0034] Below, combined Figures 1 to 3 , the above-mentioned rapid positioning fixture 100 is further explained.

[0035] like Figure 1 As shown, the base 10 includes a base body 11 and a pad 12. The base body 11 is connected to the positioning frame 20 and the guide frame 30. The pad 12 is set in the limiting space 60 to support the workpiece to improve the applicability to workpieces of different thicknesses.

[0036] like Figure 1 As shown, the positioning frame 20 includes a limit block 21, a fixed arm 22 and a support arm 23. The limit block 21 is connected to the base 10, the fixed arm 22 is connected to the limit block 21, the support arm 23 is spaced apart from the fixed arm 22, and is threadedly connected to the auxiliary positioning assembly 40, wherein the positioning frame 20 has a first positioning surface 221 and a second positioning surface 211, the first positioning surface 221 is provided on the fixed arm 22, and the second positioning surface 211 is provided on the limit block 21.

[0037] like Figures 1 to 2 As shown, the guide frame 30 includes a frame body 31 and a cover plate 32 . The frame body 31 is connected to the base 10 , and the cover plate 32 is connected to the frame body 31 and forms a sliding groove with the frame body 31 .

[0038] like Figure 3As shown, the auxiliary positioning assembly 40 includes an auxiliary actuator 41 and a flexible pad 42. The auxiliary actuator 41 is installed on the positioning frame 20 and drives the flexible pad 42 to approach or move away from the first positioning surface 221 along the first direction F1. The flexible pad 42 is arranged in the limiting space 60 for contacting the workpiece, wherein the flexible pad 42 is selected to be rubber. When the flexible pad 42 pushes the workpiece to resist the first positioning surface 221, when the clamping positioning assembly 50 is pushed along the second direction F2, the flexible pad 42 is slightly deformed by the thrust of the clamping positioning assembly 50, thereby causing the workpiece to move along the second direction F2 until the workpiece contacts the second positioning surface 211, thereby achieving fixation of the workpiece.

[0039] Specifically, if Figure 3 As shown, the auxiliary actuator 41 includes an auxiliary screw 411, a mounting block 412 and a connecting member 413, wherein the auxiliary screw 411 is threadedly connected to the support arm 23 of the positioning frame 20, and the mounting block 412 is installed on the auxiliary screw 411. The connecting member 413 is a bolt, and is passed through the flexible pad 42 and the mounting block 412 and connected to the auxiliary screw 411 to fix the flexible pad 42 on the mounting block 412. More specifically, the flexible pad 42 includes a contact portion and an extension portion, and the extension portion and the mounting block 412 is abutted, and the mounting block 412 is provided with a mounting groove 414 for accommodating the extension portion. In order to facilitate the installation of the connecting member 413, the flexible pad 42 is provided with a through hole 423 and an avoidance hole 424 connected to the through hole 423. The connecting member 413 passes through the through hole 423 and abuts against the inner wall of the avoidance hole 424. Furthermore, the auxiliary actuator 41 also includes a rotating rod 43, which is connected to the end of the auxiliary screw 411 away from the mounting block 412 to facilitate the control of the rotation of the auxiliary screw 411.

[0040] like Figure 2 As shown, the clamping positioning assembly 50 includes a clamping screw 51 and a clamping block 52. The clamping screw 51 is threadedly connected to the guide frame 30. The clamping block 52 is rotatably connected to the clamping screw 51 and is slidably connected to the slide groove of the guide frame 30. Specifically, the clamping block 52 is provided with a movable groove 521 and a through groove 522 connected to the movable groove 521. The clamping screw 51 includes a clamping ring 511, a transfer rod 512 and a threaded rod 513. The clamping ring 511 is movably connected to the movable groove 521. The transfer rod 512 is passed through the through groove 522 and is connected to the threaded rod 513. The threaded rod 513 is threadedly connected to the guide frame 30.

[0041] When the quick positioning fixture 100 provided by the present application is used: the workpiece is placed in the limited space 60, the rotating rod 43 is rotated, the auxiliary screw 411 is driven to push the mounting block 412, and the flexible pad 42 on the mounting block 412 moves along the first direction F1 until the workpiece is pushed to abut against the first positioning surface 221 of the positioning frame 20, and then the pressing screw 51 is rotated to push the pressing block 52 to move in the sliding groove of the guide frame 30 along the second direction F2, and the workpiece is pushed to move along the second direction F2. Under the influence of the thrust provided by the pressing and positioning assembly 50, the flexible pad 42 generates a slight The workpiece is slightly deformed until it contacts the second positioning surface 211. It should be noted that the auxiliary positioning component 40 is only an auxiliary positioning component, used to push the workpiece to contact the first positioning surface 221, so as to calculate the installation position of the workpiece. The main clamping force on the workpiece is the clamping positioning component 50, which pushes the workpiece to contact the second positioning surface 211 through the pressure block 52 to achieve complete fixation of the workpiece, that is, the clamping positioning component 50 provides the main clamping force on the workpiece. When the clamping positioning component 50 and the positioning frame 20 cooperate to clamp the workpiece, the workpiece is fixed.

[0042] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.
