Description
Technical Field
[0001] The utility model belongs to the technical field of slow wire processing fixtures, in particular to a test piece for cutting and clamping a workpiece. Background Art
[0002] In existing slow-feed wire processing, for thinner test pieces, a single test piece is processed on the equipment, which is prone to breakage during the processing. In order to avoid damage to the test piece, multiple test pieces are often stacked for testing in actual operation. However, when multiple test pieces are stacked together, the test pieces are prone to deviation or displacement during processing, resulting in low processing accuracy and failure to meet application requirements. Utility Model Content
[0003] In order to improve the accuracy when multiple test pieces are stacked and processed, the present application provides a test piece cutting and clamping workpiece.
[0004] The present application provides a test piece for cutting and clamping a workpiece using the following technical solution:
[0005] It comprises an upper clamping plate and a lower clamping plate for clamping the test piece, the upper clamping plate and the lower clamping plate have the same shape, and are provided with a circle of stud holes spaced apart near their respective edges, and limiting studs and leveling studs are passed through the stud holes.
[0006] By adopting the above technical scheme, through the setting of the upper clamping plate and the lower clamping plate, the upper clamping plate and the lower clamping plate are the main bodies used to clamp the test pieces, and the upper clamping plate and the lower clamping plate are arranged with a circle of stud holes spaced near their respective edges, and the stud holes are penetrated by limiting studs and leveling studs. The upper clamping plate and the lower clamping plate can be fixed by the limiting studs and the leveling studs, so that multiple stacked test pieces can be clamped and fixed, which achieves the technical effect of fixing the test pieces and preventing the test pieces from shifting during the processing.
[0007] In a specific possible implementation scheme, the upper clamping plate and the lower clamping plate are aligned with through holes to form wire feeding holes.
[0008] By adopting the above technical solution, wire feeding holes are opened on the upper clamping plate and the lower clamping plate, which facilitates the wire feeding machine to perform wire feeding processing and plays a role in positioning the equipment.
[0009] In a specific possible implementation scheme, the leveling stud includes a bottom threaded portion, which is opened at the bottom position of the leveling stud, and the bottom threaded portion is divided upward into two branches to form two clamping portions, and grooves are opened on the opposite surfaces of the two clamping portions to form a vertical groove.
[0010] By adopting the above technical solution, by opening a bottom thread portion on the leveling stud, it is helpful to connect the leveling stud through threads. The bottom thread is divided upward into two branches to form two clamping parts. The clamping part forms a vertical groove by opening a groove. The two clamping parts are separated to form a spacing between the clamping parts, which is convenient for the clamping parts to play a clamping role and form a moving space for the clamping parts to approach or move away from each other.
[0011] In a specific possible implementation manner, a wedge block is installed in the vertical groove, and the wedge block is configured to be in the shape of a rectangular block.
[0012] By adopting the above technical solution, a wedge block is installed in the vertical groove. When the wedge block contacts the test piece, it can be pressed against the test piece. The wedge block is installed in the vertical groove. The vertical groove can be clamped by two clamping parts to fix the wedge block, thereby limiting the position of the test piece between the upper clamping plate and the lower clamping plate, thereby improving the fixing firmness of the upper clamping plate and the lower clamping plate to the test piece.
[0013] In a specific possible implementation manner, a top thread portion is provided at one end of the two clamping portions away from the bottom thread portion, and a gap which is narrow at the top and wide at the bottom is formed between the two top thread portions.
[0014] By adopting the above technical solution, a gap which is narrow at the top and wide at the bottom is set between the top thread parts. By setting the gap, a movement space is provided for the movement between the two top thread parts. When the top thread parts are threadedly connected with the nut, as the nut is tightened, the two top thread parts approach each other, thereby making the clamping parts approach each other, and finally realizing the clamping function.
[0015] In a specific implementation scheme, the upper splint is provided with a through slot to form a first through slot and a second through slot, the extension lines of the first through slot and the second through slot are perpendicular to each other, and the first through slot and the second through slot are provided on the side of the limiting stud away from the edge of the upper splint.
[0016] By adopting the above technical solution, by opening the first through slot and the second through slot on the upper clamping plate, the extension lines of the first through slot and the second through slot are perpendicular to each other, so that the setting positions of the first through slot and the second through slot match the shape of the test piece.
[0017] In a specific possible implementation manner, a groove is formed at a position where the lower clamping plate is aligned with the first through slot to form a first groove, and a groove is formed at a position where the lower clamping plate is aligned with the second through slot to form a second groove.
[0018] By adopting the above technical solution, through the arrangement of the first groove and the second groove, they can cooperate with the first through groove and the second through groove to play a fixing role.
[0019] In a specific possible implementation scheme, a first baffle is installed in the first through slot, and one end of the first baffle away from the upper clamping plate is inserted into the first groove; a second baffle is installed in the second through slot, and the length of the second baffle is shorter than that of the first baffle, and one end of the second baffle away from the upper clamping plate is inserted into the second groove.
[0020] By adopting the above technical solution, by setting the first baffle and the second baffle, the first baffle and the second baffle can provide a plane for the test piece to be leveled and regularized, so that multiple stacked test pieces can be aligned and set, which helps to improve the processing accuracy of the test pieces and make the processed shapes of the test pieces the same.
[0021] In summary, this application includes the following beneficial technical effects:
[0022] 1. By setting the upper clamping plate and the lower clamping plate, the upper clamping plate and the lower clamping plate provide a clamping plane for the test piece, and stud holes are opened on the upper clamping plate and the lower clamping plate. By setting the stud holes, limiting studs and leveling studs are passed through the stud holes. By setting the limiting studs and leveling studs, the upper clamping plate and the lower clamping plate can be fixed, so that the test piece is clamped and fixed, preventing multiple test pieces stacked together from being displaced during processing.
[0023] 2. By setting the leveling stud and the first baffle and the second baffle, the leveling stud includes two clamping parts, and a vertical groove is formed between the two clamping parts. By pushing the wedge block and the test piece tightly, the test piece is connected with the first baffle and the second baffle, and multiple stacked test pieces are aligned. The test piece is limited and fixed by the first baffle, the second baffle and the wedge block, so that the test piece is fixed more firmly, which helps to improve the accuracy of processing.

DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-Figure 4 This application is described in further detail.
[0030] The directional words such as "upper", "lower", "left", "right", "front" and "back" in this application only represent the relative positions in the drawings. They are for the convenience of describing this application and do not represent the absolute positions of parts and should not be regarded as limitations on this application.
[0031] The embodiment of the present application discloses a test piece for cutting and clamping a workpiece.
[0032] like Figure 1 As shown, a test piece cutting and clamping workpiece of the present embodiment includes an upper clamping plate 1 and a lower clamping plate 2, and the upper clamping plate 1 and the lower clamping plate 2 are set to be rectangles of the same shape. The upper clamping plate 1 and the lower clamping plate 2 are used to clamp the test piece 3 to be processed. The test piece 3 is a thin sheet, and its shape is a rectangle slightly smaller than the upper clamping plate 1 and the lower clamping plate 2. In the embodiment of the present application, the test piece 3 is processed in multiple stacks. Through holes are opened at aligned positions on the upper clamping plate 1 and the lower clamping plate 2 to form a wire feeding hole 11. The wire feeding hole 11 is the starting point of the wire feeding processing of the slow wire feeding machine, and plays a positioning role in the processing of the processing equipment. The upper clamping plate 1 and the lower clamping plate 2 are provided with a circle of stud holes 21 spaced apart near their respective edges. The provision of the stud holes 21 facilitates the threaded connection between the upper clamping plate 1 and the lower clamping plate 2. When the wire-cutting machine is actually used for processing, the stud holes 21 are opened near the edges of the upper clamping plate 1 and the lower clamping plate 2, which can prevent the wire-cutting machine from cutting the stud holes 21, thereby making it impossible for the upper clamping plate 1 and the lower clamping plate 2 to be threadedly connected, causing the upper clamping plate 1 and the lower clamping plate 2 to fail to clamp the test piece 3.
[0033] Reference Figure 1 and Figure 3 A limiting stud 27 is inserted into the stud holes 21 at a long side and a short side adjacent to the upper clamping plate 1 and the lower clamping plate 2. A plurality of limiting studs 27 are provided, and the plurality of limiting studs 27 together form an L shape. The limiting stud 27 is provided with threads at the top and bottom, wherein the top thread of the limiting stud 27 is inserted into the stud hole 21 of the upper clamping plate 1, and the bottom thread of the limiting stud 27 is inserted into the stud hole 21 of the lower clamping plate 2. The middle part of the limiting stud 27 is set to be a smooth cylindrical shape.
[0034] The top and bottom threads of the limiting stud 27 are connected with nuts, which are threadedly connected to the top and bottom threads of the limiting stud 27, so that the upper clamping plate 1 and the lower clamping plate 2 can be fixedly connected. When the test piece 3 is set between the upper clamping plate 1 and the lower clamping plate 2, the test piece 3 can be clamped.
[0035] Reference Figure 2 and Figure 3 The upper clamping plate 1 is provided with through slots to form a first through slot 12 and a second through slot 14, which are both arranged adjacent to the limiting stud 27, and are arranged on a side of the limiting stud 27 away from the edge of the upper clamping plate 1. The first through slot 12 is arranged close to a long side of the upper clamping plate 1, and the second through slot 14 is arranged close to a short side of the upper clamping plate 1, and the extension lines of the first through slot 12 and the second through slot 14 are perpendicular to each other. A groove is provided at a position aligned with the first through slot 12 on the lower clamping plate 2 to form a first groove 28, and a groove is provided at a position aligned with the second through slot 14 on the lower clamping plate 2 to form a second groove 29. A first baffle 13 is installed in the first through slot 12. The first baffle 13 is set in a rectangular plate shape. The first baffle 13 is vertically inserted into the first through slot 12, and the end of the first baffle 13 away from the upper clamping plate 1 is inserted into the first groove 28. The first groove 28 cooperates with the first through slot 12 to limit and install the first baffle 13. A second baffle 15 is installed in the second through slot 14. The length of the second baffle 15 is shorter than that of the first baffle 13. The second baffle 15 is vertically inserted into the second through slot 14, and the end of the second baffle 15 away from the upper clamping plate 1 is inserted into the second groove 29. The second through slot 14 and the second groove 29 are set to limit and install the second baffle 15. The extension lines of the first baffle 13 and the second baffle 15 are set vertically. When multiple test pieces 3 are stacked and clamped by the upper clamp 1 and the lower clamp 2, the two end faces of the test piece 3 close to the first baffle 13 and the second baffle 15 are respectively abutted against the first baffle 13 and the second baffle 15, so that the test piece 3 is leveled by the flat surface provided by the first baffle 13 and the second baffle 15.
[0036] Reference Figure 4, the upper clamping plate 1 and the lower clamping plate 2 are provided with leveling studs 23 in the stud holes 21 opposite to the limiting studs 27, and a plurality of leveling studs 23 are provided, and the plurality of leveling studs 23 form an L shape along the direction of the adjacent long side and the short side of the upper clamping plate 1 and the lower clamping plate 2. The leveling stud 23 includes a bottom threaded portion 25, and the bottom threaded portion 25 is provided at the bottom position of the leveling stud 23, and is used for threaded connection of the leveling stud 23. The bottom threaded portion 25 is divided upwardly and provided with two branches to form two clamping portions 26, and this setting can form a gap between the two clamping portions 26, and the setting of the gap facilitates the movement of the clamping portions 26. The relative surfaces of the two clamping portions 26 are provided with grooves to form a vertical groove 263, and a wedge block 24 is installed in the vertical groove 263, and the wedge block 24 is used in conjunction with the vertical groove 263. When in use, the operator needs to insert the vertical groove 263 into the vertical groove 263. The wedge block 24 is configured to be in a rectangular block shape, and the thickness of the wedge block 24 is configured to match the distance between the two clamping portions 26 . This configuration enables the wedge block 24 to be inserted into the vertical slot 263 .
[0037] The two clamping parts 26 are provided with a top threaded part 261 at one end away from the bottom threaded part 25. The two top threaded parts 261 are arranged to gradually approach each other upward, so that the top ends of the two top threaded parts 261 are close to each other and the bottom ends are separated, and a gap 262 with a narrow top and a wide bottom is formed between the two top threaded parts 261. The bottom threaded part 25 of the leveling stud 23 is installed in the stud hole 21 of the lower clamping plate 2, and the top threaded part 261 is installed in the stud hole 21 of the lower clamping plate 2, and the leveling stud 23 is threadedly fixed with a nut. When the nut is used to tighten the top threaded part 261, as the nut is tightened, the gap 262 becomes smaller, so that the two clamping parts 26 are close to each other, and the wedge block 24 is clamped in the vertical groove 263.
[0038] The implementation principle of the test piece cutting and clamping workpiece of this embodiment is as follows: the operator can stack multiple test pieces 3 together, put them between the upper clamping plate 1 and the lower clamping plate 2 to clamp them, and then insert the first baffle 13 and the second baffle 15 into the first through groove 12 and the second through groove 14 respectively, so that the bottom of the first baffle 13 and the second baffle 15 are respectively inserted into the first groove 28 and the second groove 29 for fixing. Push the test piece 3 toward the direction of the first baffle 13 and the second baffle 15 and contact the first baffle 13 and the second baffle 15, so that the test piece 3 is aligned and set. Insert the limit stud 27 into the stud hole 21, and tighten the limit stud 27 with a nut. Insert the leveling stud 23 into the stud hole 21, and thread the nut with the bottom threaded portion 25, then insert the wedge 24 into the vertical slot 263, and abut one end of the wedge 24 against the test piece 3. The operator can push the wedge 24 to make the wedge 24 and the test piece 3 tightly pressed, so that the two ends of the test piece 3 away from the wedge 24 are pressed against the first baffle 13 and the second baffle 15 respectively, so that multiple test pieces 3 are aligned along the direction of the upper clamping plate 1 and the lower clamping plate 2. Thread the nut with the top threaded portion 261, and when the nut is tightened, the gap 262 is reduced, the two clamping portions 26 are close to each other, and then the vertical slot 263 is reduced, the wedge 24 is clamped and fixed, and finally the test piece 3 is clamped and fixed, which is convenient for the subsequent cutting of the test piece 3 by the wire walking machine.
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
