[0011] In some embodiments, the first sliding sleeve is integrally formed on the sliding seat, and the notches are provided at three locations evenly distributed in an annular shape.

[0012] In some embodiments, the sliding fit structure includes a second sliding sleeve fixed on the sliding seat, a linear bearing is fixed in the second sliding sleeve, and the linear bearing is slidingly fitted with the sliding rod.

[0013] In some embodiments, two linear bearings are provided, and a bearing bushing is installed between the two linear bearings.

[0014] The beneficial effect of the present application is that the adjustment mechanism can accurately control the movement trajectory of the machine head through the articulation of the first connecting block and the second connecting block and the combination of the sliding rod, thereby ensuring the cutting straightness and improving the cutting accuracy.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0023] In the embodiments of this application, please refer to Figure 1-5 As shown, this composite sliding cutting machine mainly includes: a frame 1, on which a support arm 2 is installed; a cutting assembly, including a saw blade frame 3, a saw blade 4 and a motor 5, wherein the saw blade 4 and the motor 5 are installed on the saw blade frame 3, and the motor 5 is used to drive the saw blade 4; an adjusting mechanism, including a slide rod 6, a sliding seat 7, and a hinge, wherein the first end of the slide rod 6 is fixedly arranged on the support arm 2 and extends toward the saw blade frame 3; the saw blade frame 3 is hingedly arranged on the sliding seat 7, and the sliding seat 7 is slidably mounted on the slide rod 6, and the hinge is installed between the sliding seat 7 and the support arm 2.

[0024] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0025] like Figure 1 As shown, the slide bar 6 is installed on one side of the support arm 2 and the hinge, and a limiting portion 10 is provided at the second end of the slide bar 6 for limiting the position of the slide seat 7 to prevent the slide seat 7 from separating from the slide bar 6.

[0026] Specifically, the hinge includes a first connecting block 8 and a second connecting block 9 which are hinged to each other, the first connecting block 8 is hinged to the support arm 2 , and the second connecting block 9 is hinged to the sliding seat 7 .

[0027] Furthermore, a sliding matching structure 11 is provided between the sliding seat 7 and the sliding rod 6 for sliding connection between the sliding seat 7 and the sliding rod 6 , thereby driving the saw blade frame 3 to move.

[0028] like Figure 3 As shown, the sliding matching structure 11 includes a first sliding sleeve 1101 fixed on the sliding seat 7, and a plurality of slots 12 are formed on the first sliding sleeve 1101. A plurality of rollers 13 are installed in the slots 12 through an axle rod. The rolling surfaces of the rollers 13 keep in contact and close contact with the outer wall of the sliding rod 6, so as to reduce the friction between the sliding seat 7 and the sliding rod 6 during sliding, making the sliding smoother.

[0029] Specifically, the first sliding sleeve 1101 can be integrally formed on the sliding seat 7, or can be fixedly mounted on the sliding seat 7 via a connecting piece. The notches 12 are provided at three locations evenly distributed in an annular shape to achieve smoother sliding.

[0030] like Figure 4-5 As shown, the sliding fitting structure 11 includes a second sliding sleeve 1102 fixed on the sliding seat 7, and a linear bearing 14 is fixed in the second sliding sleeve 1102. The linear bearing 14 is slidingly fitted with the sliding rod 6. The friction force during sliding is reduced by reducing the contact area between the linear bearing 14 and the sliding rod 6, which makes the movement smoother and prolongs the service life of the components.

[0031] Furthermore, two linear bearings 14 are provided, and a bearing bushing 15 is installed between the two linear bearings 14 . The bearing bushing 15 provides smooth rotation support, thereby reducing component loss.

[0032] Furthermore, the saw blade frame 3 is provided with a first handle 16 and a second handle 17, which facilitates feeding the saw blade 4 and moving the cutting tool when the cutting machine is working.

[0033] Furthermore, a saw blade cover 18 is installed on the saw blade frame 3 to block the debris and dust splashed during cutting.

[0034] During use, the plate is placed at a suitable position, and the first handle 16 or the second handle 17 is pulled to drive the saw blade frame 3. The saw blade frame 3 slides on the slide rod 6 through the sliding seat 7 and the first connecting block 8 and the second connecting block 9 are hinged to achieve movement, and the saw blade frame 3 is rotated to feed the saw blade 4 downward for cutting.

[0035] The composite structure of the slide bar 6 and the hinge type is adopted to improve the cutting accuracy of the machine, while the cost is much lower than that of the hinge type structure.

[0036] So far, various embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed herein.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solution of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not drive the essence of the corresponding technical solutions away from the spirit and scope of the technical solutions of the embodiments of the present application.
