Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting fixture. Background Technology

[0002] Aluminum sheet refers to rectangular plates rolled from aluminum ingots. It is categorized into pure aluminum sheets, alloy aluminum sheets, thin aluminum sheets, medium-thick aluminum sheets, and patterned aluminum sheets. During aluminum sheet production, cutting is necessary. For example, patent CN215035554U discloses a clamping fixture for aluminum sheet cutting, including a mounting plate. The upper surface of the mounting plate has positioning holes around its perimeter for fixing to the cutting table. A slit is located in the middle of the mounting plate, and clamping plates are symmetrically arranged on both sides of the slit for holding the aluminum sheet during cutting. This clamping fixture ensures stable clamping force, prevents loosening, reduces damage to the table and wear on the cutting wheels, and improves production quality and efficiency. However, this device only clamps the aluminum sheet from both sides for easy cutting and cannot cut the aluminum sheet to a fixed length as needed. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1 to 7As shown, a cutting fixture includes: a base 1, a limiting plate 2, a clamping assembly, and a cutting assembly; the base 1 is provided with a first control structure for controlling the limiting plate 2 to slide along the length direction of the base 1 on its upper surface; the base 1 is provided with a clearance groove 11; the cutting assembly includes a circular saw blade 3, which is disposed above the clearance groove 11; the limiting plate 2 is disposed on one side of the clearance groove 11; the clamping assembly includes two clamping vertical blocks 4. Block 4 is symmetrically arranged at both ends on the other side of the clearance groove 11; a side notch 41 is provided on the side of the two clamping vertical blocks 4 that are close to each other, and a horizontal plate 5 is elastically arranged in the side notch 41 along the vertical direction. A second control structure is provided on the clamping vertical block 4 to control the downward movement of the horizontal plate 5. One end of the horizontal plate 5 extends out of the side notch 41 and is horizontally fixedly connected to two pressure plates 51. The pressure plates 51 are perpendicular to the horizontal plate 5, and the two pressure plates 51 are respectively located above the two sides of the clearance groove 11.

[0027] An clearance groove 11 is provided to allow space for the circular saw blade 3 to cut, preventing damage to the base 1 during cutting. Two clamping vertical blocks 4 are provided to clamp and fix the two sides of the board. A horizontal plate 5 and a pressure plate 51 are provided. When the second control horizontal plate 5 is moved downward, it can drive the pressure plate 51 to move downward, which can press the placed board tightly. At this time, the thickness of the board is greater than the distance between the bottom of the side notch 41 and the base 1, and the two pressure plates 51 are located above the clearance groove 11 on both sides, so they will not interfere with the cutting of the circular saw blade 3.

[0028] In use, the position of the limiting plate 2 on the base 1 is first controlled by the first control structure, that is, the distance between the limiting plate 2 and the clearance groove 11 is determined. Then the plate is placed on the base 1 so that the plate is between the two clamping vertical blocks 4, with one end of the plate abutting against the limiting plate 2. Then the two clamping vertical blocks 4 are controlled to move closer to each other to clamp the two sides of the plate. The second control structure controls the horizontal plate 5 to drive the pressure plate 51 to move downward until it presses down on the upper surface of the plate. Then the cutting component is started to cut.

[0029] One end of the board abuts against the limiting plate 2, and the other end is clamped by the clamping vertical block 4 to hold the side of the board. The second control structure controls the pressure plate 51 to press the board downward. The circular saw 3 of the cutting component cuts the board. The position of the limiting plate 2 is changed by the first control structure, which changes the distance between the limiting plate 2 and the clearance groove 11, thereby changing the length of the cut board. The board is cut to a fixed length according to the requirements.

[0030] Furthermore, such as Figures 1 to 6As shown, the second control structure includes a first threaded rod 61 and a first motor 62. The lower end of the first threaded rod 61 is rotatably connected to the bottom of the side notch 41, and the upper end extends upward and connects to the output end of the first motor 62. The horizontal plate 5 is provided with a threaded through hole that mates with the first threaded rod 61, and also has a vertical rod 63. The vertical rod 63 passes vertically through the horizontal plate 5 and is fixedly connected inside the side notch 41. Compression springs 64 are fitted on both the first threaded rod 61 and the vertical rod 63, and the compression springs 64 are located below the horizontal plate 5. Under normal conditions, the elastic force of the compression springs 64 will cause the horizontal plate 5 to move upward away from the bottom of the side notch 41, and the pressure plate 51 will also move upward. When it is necessary to press the plate, the first motor 62 is controlled to drive the first threaded rod 61 to rotate. Due to the restriction of the vertical rod 63, the horizontal plate 5 can only move in the vertical direction. The horizontal plate 5 is controlled to move downward, the compression springs 64 are compressed, and the pressure plate 51 is driven downward until the plate is pressed down.

[0031] Furthermore, such as Figures 1 to 3 As shown, the first control structure includes a second threaded rod 71, a sliding plate 72, and a second motor 73. A long strip-shaped groove 12 is provided on the base 1. The lower end of the sliding plate 72 is slidably connected to the long strip-shaped groove 12, and its upper end is fixedly connected to the limiting plate 2 on the side near the clearance groove 11. A cavity is provided inside the base 1, and the cavity communicates with the long strip-shaped groove 12. The second threaded rod 71 is rotatably disposed in the cavity along the axis of the second threaded rod 71. One end of the second threaded rod 71 extends out of the base 1 and is fixedly connected to the output end of the second motor 73. A control nut 74 is threadedly connected to the second threaded rod 71, and the control nut 74 is fixedly connected to the sliding plate 72. The slide plate 72 is slidably connected in the elongated slide groove 12. The sliding direction of the slide plate 72 is parallel to the second threaded rod 71. The elongated slide groove 12 restricts the slide plate 72, so that the slide plate 72 can only move along the elongated slide groove 12. The control nut 74 is connected to the slide plate 72. The control nut 74 can only move along the length direction of the second threaded rod 71. When the second motor 73 drives the second threaded rod 71 to rotate, the control nut 74 drives the slide plate 72 to move, thereby changing the position of the limiting plate 2, thus changing the length of the cut plate.

[0032] Furthermore, such as Figure 1 , Figure 3 and Figure 4As shown, the clamping assembly includes a rotating rod 81 and a third motor 82. The base 1 has a clamping groove 13 parallel to the clearance groove 11. The rotating rod 81 is rotatably connected within the clamping groove 13. One end of the rotating rod 81 is fixedly connected to the output shaft of the third motor 82. Two clamping vertical blocks 4 are respectively disposed at both ends of the rotating rod 81. The rotating rod 81 has two external thread sections with opposite thread directions. The bottom of each clamping vertical block 4 is threadedly connected to the corresponding external thread section. The bottom of each clamping vertical block 4 has a threaded hole through which the rotating rod 81 passes. The threaded hole engages with the corresponding external thread. When the rotating rod 81 rotates, it can drive the two clamping vertical blocks 4 to move closer or further apart, thereby clamping plates of different widths.

[0033] Furthermore, such as Figures 1 to 3 As shown, two limiting plates 2 are provided, and the sides of the two limiting plates 2 near the clearance groove 11 are located on the same plane. In use, the plate simultaneously abuts against the sides of the two limiting plates 2, improving stability.

[0034] Furthermore, such as Figures 1 to 4 and Figure 7 As shown, the cutting assembly includes a support frame 91, a placement block 92, a telescopic rod 93, and a cutting motor. The placement block 92 is horizontally slidably connected to the support frame 91 along the width direction of the base 1. The telescopic rod 93 is fixed to the placement block 92, with its free end pointing downwards and connected to a connecting plate. The cutting motor is fixed to the connecting plate, and its output end is connected to the circular saw blade 3. Specifically, the support frame 91 has a transverse groove, and one side of the placement block 92 is slidably connected to the transverse groove. The movement of the placement block 92 is achieved by a rotating screw and a matching threaded hole on the placement block 92. The telescopic rod 93 allows adjustment of the downward movement distance of the lower circular saw blade 3 according to different movable materials, facilitating the pressing of materials of different thicknesses.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
