Description

Technical Field

[0001] This utility model relates to the field of cutting machine guard technology, and in particular to a novel quick-installation structure for a cutting machine guard. Background Technology

[0002] In the field of modern machining, cutting machines are widely used as key equipment in industries such as metal processing, wood processing, and stone processing. Currently, most cutting machine guards are fixed to the machine housing using the traditional method of screws. Specifically, during assembly, operators need to use tools such as screwdrivers and wrenches to pass multiple screws sequentially through the pre-drilled mounting holes on the guard and screw them into the corresponding threaded holes on the machine housing, ensuring a secure and snug fit through repeated tightening. The structural feature of this fixing method is that it relies on the mechanical engagement of the screws and threaded holes to achieve a certain degree of stability.

[0003] However, the above methods have certain drawbacks. First, the operation process is relatively cumbersome, requiring each screw to be unscrewed or tightened individually each time the cover is disassembled or installed, consuming considerable time and manpower. Second, it places high demands on the operator's working space; in confined spaces such as inside pipes or within equipment compartments, screwdrivers are difficult to maneuver, making screw disassembly and installation extremely difficult, hindering equipment maintenance and on-site operations. Third, because the cover is fixed in a relatively fixed position by the screws, it restricts the range of motion of the cutting machine's blades, making it difficult to increase the cutting depth and meet the processing needs of complex workpieces or thick materials. Therefore, a new quick-installation structure for the cutter's cover needs to be designed.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides a novel quick-install structure for the protective cover of a cutting machine, which solves the problems of traditional cutting machine protective covers being fixed with screws, resulting in cumbersome operation, difficulty in disassembling and assembling in confined spaces, and limitations on cutting depth.

[0006] This utility model embodiment adopts the following technical solution: a novel quick-release structure for a cutting machine's protective cover. It includes a protective cover top cover, a protective cover body, and an iron base plate. The iron base plate has two sets of protrusions with a pre-existing gap between them. A fixing pin is installed between the two sets of protrusions. One end of the protective cover body is mounted on the fixing pin via a movable sleeve. The protective cover top cover is connected to the protective cover body by a first screw. A notched arc groove is formed on the surface of the protective cover top cover, fitting snugly against the side wall of the protective cover body. A depth adjustment frame is installed on the iron base plate, with a small gap between the depth adjustment frame and the protective cover top cover. A fixing limiting part is fixed on the inner wall of the protective cover top cover, with a hexagonal nut embedded inside. A locking screw passes through the groove, with one end of the locking screw threaded through the protective cover top cover and engaged with the hexagonal nut in the limiting part. A washer is fitted onto the shaft of the locking screw. A limiting block is installed on the inner wall of the protective cover top cover, and a corresponding limiting groove is formed on the protective cover body. A limiting elastic positioning part for controlling the tightening / loosening of the depth adjustment frame and the protective cover top cover is provided in the limiting groove.

[0007] Furthermore, the elastic positioning part includes a quick-adjustment knob that is slidably embedded in the limiting groove, and the quick-adjustment knob part is partially accommodated in the space enclosed by the protective cover body and the protective cover top cover;

[0008] A contact portion extends from the quick-adjustment knob into the body of the protective cover. A spring connects the contact portion to the inner wall of the protective cover. In the initial state, the spring, through elastic compression, makes the contact portion of the quick-adjustment knob press against the inner wall of the limiting block away from the side of the depth adjustment frame. At the same time, the quick-adjustment knob body is in contact with the inner wall of the limiting groove, with the help of the spring preload and the L-shaped limiting structure.

[0009] Furthermore, the top cover of the protective cover is made of plastic.

[0010] Furthermore, the depth adjustment frame is provided with scale markings along the arc direction of the arc-shaped limiting plate, and the scale markings are adapted to the notch arc groove of the protective cover and the adjustment trajectory of the quick-adjustment knob.

[0011] Furthermore, the upper cover of the protective cover has an arc-shaped contour structure.

[0012] Furthermore, the limiting block is an inverted L-shape.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] A novel quick-release structure for a cutting machine's protective cover allows for flexible rotation of the cover body through the engagement of two sets of protrusions on the iron base plate and fixing pins. Combined with the curved surface adaptation and minute gap between the depth adjustment frame and the cover's upper cover, it provides guidance for adjusting the cutting depth. The notch groove fits snugly against the side wall of the cover body to form an arc-shaped limiting structure, enhancing the overall stability and reliability of the protection. During operation, the limiting elastic positioning part, locking screws, hexagonal nuts, and other components work together, allowing for quick tightening or loosening of the depth adjustment frame and the cover's upper cover via a simple sliding quick-adjustment knob. This eliminates the need for complex tools, significantly improving operational efficiency and adapting to cutting operations of materials of different thicknesses and types.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1 to 5 As shown, this utility model embodiment provides a novel quick-release structure for a cutting machine's protective cover, including a protective cover top cover 1, a protective cover body 5, and an iron base plate 8;

[0027] The iron base plate 8 has two sets of protrusions 801 with a certain gap, and a fixing pin 7 is fixedly installed between the two sets of protrusions 801. One end of the protective cover body 5 is installed on the fixing pin 7 by a movable sleeve. This connection method allows the protective cover body 5 to rotate flexibly with the fixing pin 7 as the axis.

[0028] The upper cover 1 of the protective cover is rigidly fixed to the body 5 of the protective cover by two sets of first screws 6, and the two constitute an arc-shaped protective component. The upper cover 1 of the protective cover has an arc-shaped contour structure, and its surface is provided with a notch arc groove 101. The notch arc groove 101 fits against the side wall of the body 5 of the protective cover to form an arc-shaped limiting structure.

[0029] Meanwhile, at one end of the iron base plate 8 away from the protrusion 801, a depth adjustment frame 9 composed of a fixing block and an arc-shaped limiting plate is fixedly installed. The curvature of the arc-shaped limiting plate is perfectly matched with the notch arc groove 101, and a small gap is left between the depth adjustment frame 9 and the upper cover 1 of the protective cover. The trajectory guidance during the cutting depth adjustment is realized through the arc surface adaptation. With the pin connection and locking structure between the protective cover and the iron base plate 8, a stable and adjustable protective structure is constructed.

[0030] Furthermore, an inverted "L"-shaped limiting block 102 is fixedly installed on the inner wall of the protective cover 1, and a limiting groove 501 is correspondingly opened on the protective cover body 5. An elastic positioning part is provided in the limiting groove 501. The elastic positioning part includes a quick-adjustment knob 4 that is slidably embedded in the limiting groove 501. The quick-adjustment knob 4 is partially accommodated in the space enclosed by the protective cover body 5 and the protective cover 1.

[0031] Furthermore, a contact portion (not shown in the figure) extends from the quick-adjustment knob 4 into the protective cover body 5. A spring 12 is connected between the contact portion and the inner wall of the protective cover cover 1. In the initial state, the spring 12 uses elastic compression force to make the contact portion of the quick-adjustment knob 4 press against the inner wall of the limiting block 102 away from the side of the depth adjustment frame 9. At the same time, the body of the quick-adjustment knob 4 is in contact with the inner wall of the limiting groove 501. With the help of the pre-tightening force of the spring 12 and the "L"-shaped limiting structure, the quick-adjustment knob 4 can be accurately positioned and stably slidably adjusted.

[0032] The inner wall of the protective cover 1 is fixed with a limiting part 103, which is fitted with a hexagonal nut 3. At the same time, a locking screw 11 passes through the waist groove 901. One end of the locking screw 11 passes through the protective cover 1 and is screwed into the hexagonal nut 3 in the limiting part 103. Meanwhile, the shaft of the locking screw 11 is fitted with a washer 10. After assembly, the washer 10 fits tightly against the outside of the depth adjustment frame 9. Through the limiting part 103 limiting the nut, the threaded connection between the locking screw 11 and the nut, and the pressure bearing effect of the washer 10, the fastening / loosening control of the depth adjustment frame 9 and the protective cover assembly is realized, providing a stable and adjustable connection structure for cutting depth adjustment.

[0033] Specifically, the upper cover 1 of the protective cover is made of plastic;

[0034] Specifically, the depth adjustment frame 9 is provided with scale markings along the arc direction of the arc-shaped limiting plate. The scale markings are adapted to the notch arc groove 101 of the protective cover 1 and the adjustment trajectory of the quick-adjustment knob 4. The operator can observe the scale and control the angle of rotation of the protective cover assembly around the fixing pin 7 by sliding the quick-adjustment knob 4 and tightening the locking screw 11, thereby quantitatively adjusting the cutting depth and achieving precise adaptation to cutting operations of materials of different thicknesses and types.

[0035] During assembly, the iron base plate 8 forms a hinge fulcrum with the protective cover body 5 through two sets of protrusions 801 and fixing pins 7, allowing the protective cover body 5 to rotate around the fixing pins 7. The protective cover top cover 1 is rigidly fixed to the protective cover body 5 by the first screw 6, forming an arc-shaped protective component. Its notch arc groove 101 fits against the side wall of the protective cover body 5, forming an arc-shaped limiting structure. The depth adjustment frame 9 is fixed to the end of the iron base plate 8. Its arc-shaped limiting plate matches the arc of the notch arc groove 101 and leaves a small gap with the protective cover top cover 1 to guide the rotation trajectory of the protective cover.

[0036] The quick-adjustment knob 4 is embedded in the limiting groove 501 of the protective cover body 5 and is connected to the spring 12 through the contact part. In the initial state, the spring 12 is pre-tightened, so that the contact part of the quick-adjustment knob 4 is in close contact with the inner wall of the "L"-shaped limiting block 102 (the side away from the depth adjustment frame 9), ensuring that the quick-adjustment knob is stably positioned. The locking screw 11 passes through the waist groove 901 of the depth adjustment frame 9 and is screwed into the hexagonal nut 3 in the upper cover 1 of the protective cover. The protective cover assembly is locked to the iron base plate 8 through the washer 10. At this time, the position of the protective cover is fixed and the cutting depth is locked.

[0037] When the cutting depth needs to be adjusted, the operator moves the quick-adjustment knob 4 to the right, overcoming the preload of the spring 12 and moving its contact part towards the depth adjustment frame 9. This compresses the spring 12 and stores elastic potential energy. The movement of the quick-adjustment knob 4 pushes the limiting part 103 of the cover 1 through the contact part, causing the hexagonal nut 3 to move to the right. This causes the locking screw 11 to move to the right simultaneously, and the washer 10 disengages from the outside of the depth adjustment frame 9, releasing the lock on the cover assembly. At this time, the cover body 5 and the cover 1 are unrestrained and can rotate around the fixing pin 7. Because the arc-shaped limiting plate of the depth adjustment frame 9 matches the arc surface of the notch groove 101, the cover assembly rotates along a preset arc trajectory, preventing wobbling. By observing the scale markings on the depth adjustment frame 9 and combining the sliding distance of the quick-adjustment knob 4, the operator can precisely control the rotation angle of the cover, achieving quantitative adjustment of the cutting depth (such as increasing or decreasing the relative height between the iron base plate and the cover).

[0038] After adjusting to the target depth, release the quick-adjustment knob 4. The spring 12 releases its elastic potential energy, pushing the quick-adjustment knob 4 to reset to the left. The contact part re-adheres tightly to the inner wall of the "L"-shaped limiting block 102, restoring the initial positioning state. At the same time, the hexagonal nut 3 moves to the left along with the cover 1, causing the locking screw 11 to reset. The washer 10 again tightly adheres to the outside of the depth adjustment frame 9, and the cover assembly is rigidly locked to the iron base plate 8 through the threaded connection. At this time, the rotational freedom of the cover is restricted, the cutting depth is fixed, and stable cutting operations can be performed. The entire process, through the elastic linkage of the spring 12, the arc-shaped guide structure, and the scale markings, achieves a highly efficient operating cycle of rapid unlocking, precise adjustment, and reliable locking, meeting the flexible adaptation needs of cutting depths for different materials.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
