[0031] As shown in Figure 1 The embodiment provides a cutting device, which comprises a guide seat 1, a cutting assembly 2 and a limiting assembly 3.
[0032] As shown in Figure 1 The above-mentioned guide seat 1 is, for example, a long strip type block structure or a long strip type plate structure with a certain thickness. The guide seat 1 extends along the first direction X1.
[0033] The cutting assembly 2 is slidingly connected to the guide base 1 in the first direction X1, that is, the cutting assembly 2 can slide along the extension direction of the guide base 1. For example, the guide base 1 is provided with a sliding rail extending in the first direction X1, and the cutting assembly 2 is provided with a sliding part matched with the sliding rail, so that the sliding connection between the guide base 1 and the cutting assembly 2 is realized by the cooperation between the sliding part and the sliding rail. Alternatively, the guide base 1 is provided with a sliding groove extending in the first direction X1, and the cutting assembly 2 is provided with a sliding block matched with the sliding groove, so that the sliding connection between the guide base 1 and the cutting assembly 2 is realized by the cooperation between the sliding block and the sliding groove. In the second direction X2, at least part of the cutting assembly 2 protrudes from the side of the guide base 1 close to the object to be cut, that is, as shown in the view angle, part of the cutting assembly 2 protrudes from the lower surface of the guide base 1. The second direction X2 is arranged at an angle with the first direction X1, for example, the angle is 90°. Figure 1
[0034] The limiting assembly 3 is slidingly connected to the guide base 1 in the first direction X1, that is, the cutting assembly 2 can slide along the extension direction of the guide base 1. For example, the limiting assembly 3 and the guide base 1 are slidingly connected by the cooperation between the sliding groove and the sliding block, and the specific connection mode can refer to the sliding connection mode between the cutting assembly 2 and the guide base 1, which will not be described herein. The limiting assembly 3 can be locked to the guide base 1, and is used for limiting the cutting assembly 2 in the first direction X1. For example, in the first direction X1, the cutting assembly 2 abuts against the limiting assembly 3, so that the cutting assembly 2 cannot slide in the first direction X1, that is, the cutting assembly 2 is limited in the first direction X1.
[0035] Thus, the cutting device provided by the embodiment has the following advantages. When cutting operation is needed, the guide seat 1 is first placed on the object to be cut and linearly positioned, then the limiting assembly 3 is moved on the guide seat 1 in the first direction X1 and the length (preset length) to be cut is determined, after that, the limiting assembly 3 is locked on the guide seat 1, finally, the worker operates to move the cutting assembly 2 on the guide seat 1 in the first direction X1, for example, the worker pushes the cutting assembly 2, with the movement of the cutting assembly 2, the part of the cutting assembly 2 protruding from the guide seat 1 can cut the object to be cut, until the cutting assembly 2 abuts against the limiting assembly 3 and cannot continue to move in the first direction X1, thus the cutting operation of the preset length is completed. In the above cutting operation process, the guide seat 1 needs to be linearly positioned only once, and the worker only needs to push the cutting assembly 2 once to complete the cutting of the object to be cut of the preset length, without the need for multiple people to linearly position the cutting device multiple times, and without the need for multiple people to perform cutting operation multiple times, thus the cutting efficiency is improved and the labor cost is reduced. In the above cutting process, the worker pushes the cutting assembly 2 to perform cutting operation without holding the cutting tool, thus the safety hazard in the cutting process is reduced.
[0036] In some embodiments, in combination with Figure 1 、 Figure 2 , the guide seat 1 is provided with the first sliding groove 11 extending in the first direction X1, it is easy to understand that the first sliding groove 11 extends in the first direction X1 while the opening direction of the slot is parallel to the third direction X3, the first direction X1, the second direction X2 and the third direction X3 are arranged at an angle with each other, for example, the angle is 90°. In other words, taking the view angle shown in Figure 1 as an example, the first sliding groove 11 extends in the extension direction of the guide seat 1, and the opening direction of the slot is parallel to the horizontal direction. The limiting assembly 3 is slidingly connected to the first sliding groove 11.
[0037] In combination with Figure 3 、 Figure 4 , the limiting assembly 3 includes the sliding piece 31, the stop piece 32 and the locking piece 4. The sliding piece 31 is slidingly connected to the first sliding groove 11, for example, the first sliding groove 11 is a dovetail sliding groove, and the sliding piece 31 is a dovetail sliding block matched with the first sliding groove 11.
[0038] The aforementioned stop 32 is fixedly connected to the sliding member 31 and is located outside the first groove 11. The stop 32 is, for example, elongated in shape, and is fixedly connected to the sliding member 31, for example, by bolts or welding. The stop 32 can abut against the aforementioned cutting assembly 2 in the first direction X1.
[0039] The aforementioned locking member 4 passes through both the sliding member 31 and the stop member 32 along the third direction X3 and is connected to the aforementioned guide seat 1 to lock the sliding member 31, the stop member 32 and the aforementioned guide seat 1. Here, the connection between the locking member 4 and the guide seat 1 is, for example, abutment or bolt connection. The locking element 4 is, for example, a bolt. The locking element 4 is used to lock the position of the sliding element 31 and the stop element 32. For example, after the locking element 4 passes through the sliding element 31 and the stop element 32, the end of the locking element 4 near the first slide groove 11 abuts against the bottom of the first slide groove 11. The friction between the end of the locking element 4 and the bottom of the first slide groove 11 locks the position of the sliding element 31 and the stop element 32 in the first direction X1. Alternatively, multiple locking holes adapted to the locking element 4 are evenly provided along the first direction X1 at the bottom of the first slide groove 11. After the locking element 4 passes through the sliding element 31 and the stop element 32, the end of the locking element 4 near the first slide groove 11 is inserted into the corresponding locking hole at the bottom of the first slide groove 11. The locking element 4 and the locking hole can also lock the position of the sliding element 31 and the stop element 32 in the first direction X1 by plugging and connecting them.
[0040] In the aforementioned cutting device, a first groove 11 extending along the first direction X1 is provided on the guide seat 1, and the limiting component 3 is configured as follows: a sliding member 31 is slidably connected to the first groove 11; a stop member 32 is fixedly connected to the sliding member 31 and can abut against the cutting component 2 in the first direction X1; and a locking member 4 passes through both the sliding member 31 and the stop member 32 along the third direction X3. This allows the locking member 4 to lock the positions of the sliding member 31 and the stop member 32 in the first direction X1. Thus, when the cutting component 2 abuts against the stop member 32, the stop member 32 can limit the cutting component 2 in the first direction X1. The structure is simple and easy to use.
[0041] In some embodiments, combined with Figure 1 , Figure 2 As shown, the guide seat 1 is provided with a second slide groove 12 extending along the first direction X1, and the first slide groove 11 and the second slide groove 12 are arranged along the second direction X2.
[0042] The aforementioned cutting assembly 2 includes a cutting blade 21, a roller 22, and a rotating shaft 23.
[0043] The cutting knife 21 is, for example, a rectangular blade or a circular blade, and is connected to the rotating shaft 23. In the second direction X2, at least part of the cutting knife 21 protrudes from the side of the guide seat 1 close to the object to be cut, that is, as shown in the view angle, part of the cutting knife 21 protrudes from the lower surface of the guide seat 1. Figure 2
[0044] The roller 22 is arranged in the second sliding groove 12, and is rotationally connected to the rotating shaft 23. The axis of the roller 22 is arranged in parallel with the third direction X3. It is not difficult to understand that, in order to enable the roller 22 to smoothly roll in the second sliding groove 12, in the second direction X2, there is a gap between the outer contour of the roller 22 and the upper sidewall in the groove body of the second sliding groove 12.
[0045] The rotating shaft 23 extends along the third direction X3. One end of the rotating shaft 23 is rotationally connected to the roller 22, for example, in the following manner: a bearing is arranged on the rotating shaft 23, and a mounting hole is arranged at the center of the roller 22 and is adapted to the bearing, and the roller 22 is mounted on the outer ring of the bearing through the mounting hole, so that the roller 22 and the rotating shaft 23 are rotationally connected through the bearing. The other end of the rotating shaft 23 is connected to the cutting knife 21, for example, in the following manner: welding or threaded connection. It is not difficult to understand that, when the cutting knife 21 is a circular blade, the connection between the rotating shaft 23 and the cutting knife 21 can also be rotational connection.
[0046] In the cutting device, by arranging the cutting assembly 2 as the cutting knife 21, the roller 22 arranged in the second sliding groove 12, and the rotating shaft 23 extending along the third direction X3, the cutting action is realized by pushing the rotating shaft 23 and enabling the cutting knife 21 to move in the first direction X1, and the sliding motion of the cutting assembly 2 in the second sliding groove 12 is changed into rolling motion by arranging the roller 22, which reduces the friction between the cutting assembly 2 and the second sliding groove 12, facilitates the movement of the cutting assembly 2 in the first direction X1, and further facilitates the use of the cutting device.
[0047] In some embodiments, as shown in Figure 2 , Figure 4 As shown, the cutting assembly 2 further comprises a fixing member 24. The fixing member 24 comprises a connecting portion 241 and a limiting portion 242. The limiting portion 242 is in the shape of a cylindrical block, and the limiting portion 242 and the cutting knife 21 are arranged on opposite sides of the guide seat 1. The connecting portion 241 is in the shape of a cylindrical rod, and the connecting portion 241 is arranged in the groove bottom of the second sliding groove 12 along the second direction X2, and the two ends of the connecting portion 241 are fixedly connected with the rotating shaft 23 and the limiting portion 242, respectively. The connecting portion 241 and the rotating shaft 23 are connected by welding or screwing, and the connecting portion 241 and the limiting portion 242 are connected by screwing or welding.
[0048] The fixing member 24 can move along the first direction X1, and the limiting portion 242 can abut against the stopper 32 along the first direction X1, so that the fixing member 24 cannot continue to move along the first direction X1, and the stopper 32 of the limiting assembly 3 can limit the movement of the cutting assembly 2 along the first direction X1. It is understood that, in order to facilitate the movement of the fixing member 24 along the first direction X1, a long strip-shaped opening is arranged in the groove bottom of the second sliding groove 12, and the fixing member 24 is fixedly connected with the rotating shaft 23 through the opening.
[0049] In the cutting device, the fixing member 24 comprising the connecting portion 241 and the limiting portion 242 is arranged in the cutting assembly 2, the rotating shaft 23 is connected with the limiting portion 242 through the connecting portion 241 to fix the rotating shaft 23 and prevent the rotating shaft 23 from being separated from the second sliding groove 12, and the limiting portion 242 abuts against the stopper 32 to limit the movement of the cutting assembly 2 along the first direction X1, so that the cutting device has a simple structure, is convenient to manufacture, and is convenient to install and use.
[0050] In some embodiments, in combination with Figure 3 , Figure 4As shown, the cutting device further comprises a guide 5, for example in the form of a long strip-shaped plate structure, extending along the first direction X1 and arranged between the limiting portion 242 and the guide seat 1. The two ends of the guide 5 in the first direction X1 are fixedly connected to the guide seat 1, for example by bolts. Through the above arrangement, the gap between the limiting portion 242 and the guide seat 1 can be reduced, avoiding the cutting assembly 2 from shaking when sliding along the guide seat 1, and providing a guiding effect for the cutting assembly 2. At the same time, the guide 5 can avoid the limiting portion 242 directly contacting the guide seat 1, avoiding wear between the limiting portion 242 and the guide seat 1 after long-term use. Moreover, through the above arrangement, even if the guide 5 is worn by the limiting portion 242 after long-term use, the guide 5 can be replaced, without the need to replace the entire guide seat 1, facilitating maintenance and repair, and reducing material costs.
[0051] In some embodiments, as shown in Figure 1 , Figure 3 the cutting device further comprises a push rod 6, for example in the form of a cylindrical rod structure. The push rod 6 is fixedly connected to the end of the rotating shaft 23 and located on the side of the cutting knife 21 away from the roller 22. The fixed connection between the push rod 6 and the rotating shaft 23 is, for example, by threaded connection or welding. Through the above arrangement, when the worker performs the cutting operation, the entire cutting assembly 2 can be moved along the extension direction of the guide seat 1 by holding and pushing the push rod 6, thereby completing the cutting operation. In the above process, the push rod 6 extends upward, shortening the distance between the operator and the cutting device, so that the worker does not need to bend down or squat to push the cutting assembly 2, reducing the labor intensity of the worker, and improving the practicality of the cutting device.
[0052] In some embodiments, as shown in Figure 1 , Figure 3 the cutting device further comprises a support 7. The support 7 is fixedly connected to the two ends of the guide seat 1 in the first direction X1. The support 7 is used to provide support for the guide seat 1. For example, the support 7 comprises a connecting piece fixedly connected (for example, welded) to the guide seat 1 and a support 7 perpendicular to the connecting piece for supporting. That is, the connecting piece and the support 7 combine to form an L-shaped plate structure. Through the above arrangement, the size of the guide seat 1 in the third direction X1 is increased, thereby increasing the contact area with the object to be cut and improving the stability of the guide seat 1 during cutting.
[0053] In some embodiments, as shown in Figure 1 , Figure 3As shown in the drawings, the cutting device further comprises a pressing piece 8, for example, a circular plate structure. The pressing piece 8 is threadedly connected to the support piece 7 at a side close to the object to be cut. The pressing piece 8 is used to press the object to be cut. Through the above arrangement, the object to be cut can be pressed by the pressing piece 8 during the cutting operation, so as to avoid the movement of the object to be cut and cause the error of the cutting result. In addition, since the pressing piece 8 is threadedly connected to the support piece 7, the distance between the support piece 7 and the object to be cut can be adjusted by rotating the pressing piece 8 through the thread cooperation, so as to realize the adjustment of the height of the guide seat 1, and then the cutting depth of the cutting assembly 2 when cutting the object can be adjusted, so that the cutting assembly 2 can adapt to the cutting of the object to be cut with different thicknesses, and the applicability of the cutting device is improved.
[0054] In some embodiments, as shown in Figure 1 、 Figure 3 The cutting device further comprises a handle 9, for example, an inverted U-shaped structure. The handle 9 is arranged at both ends of the guide seat 1 in the first direction X1 and located at a side of the guide seat 1 away from the object to be cut, that is, the handle 9 is arranged on the upper side of the guide seat 1 in the view angle shown in the drawings. Through the above arrangement, when the work personnel straighten the guide seat 1 before the cutting operation, the guide seat 1 can be lifted and carried or adjusted in position by holding the handle 9, which is convenient to use and improves the practicability of the cutting device. Figure 1
[0055] In some embodiments, as shown in Figure 3 、 Figure 4 The guide seat 1 is provided with scale marks 10 arranged along the first direction X1. The scale marks 10 are arranged on the same side of the guide seat 1 as the limiting assembly 3. Through such arrangement, the work personnel can conveniently judge the position of the limiting assembly 3 on the guide seat 1, and conveniently cut the object to be cut with a preset length, which improves the practicability of the cutting device. The stop piece 32 has a sharp end pointing to the scale marks 10, which is convenient for the work personnel to visually judge the position of the stop piece 32 on the guide seat 1.
