Description

TECHNICAL FIELD

[0001] The utility model relates to cutting equipment technical field especially relates to a cutting device. BACKGROUND

[0002] Aluminum bar is a rectangular or square solid metal conductor, usually with a large cross-sectional area. Its shape is regular, generally long strip flat shape, like a relatively wide thick metal strip. For example, the aluminum bar used in some large power distribution cabinet, the width may be tens of millimeters, the thickness also has several millimeters to tens of millimeters, the appearance is relatively thick. Aluminum bar products are usually used for power transmission and distribution, and the insulating layer can prevent the aluminum bar from short circuiting with the surrounding metal objects or other conductive bodies. For example, in the power distribution cabinet, if the aluminum bars of different phase sequences do not have insulating layers, they are easy to contact each other and cause short circuit failure, causing electrical equipment damage and even fire and other serious consequences. The insulating layer can withstand a certain voltage to ensure the safe operation of the aluminum bar within the rated voltage range.

[0003] When the aluminum bar needs to be electrically connected, such as welding, crimping or using bolt connection, the insulating layer at the connection site needs to be removed. Because the insulating layer will hinder the good conduction of current, affecting the electrical performance of the connection. For example, in a substation, when different sections of aluminum bars are connected by bolts to form a busbar, the connecting surface must remove the insulating layer to allow the aluminum bars to directly contact each other, ensuring a low-resistance electrical connection to ensure efficient transmission of electrical energy. If the insulating layer is not removed, a large contact resistance will be generated at the connection site, causing heating and possibly causing electrical failure.

[0004] In the prior art, the insulating layer is first cut by laser, and then heated and peeled off. Due to the limitation of product structure, the laser cannot cut all areas, and manual cutting with a blade is required for secondary cutting. However, manual cutting is time-consuming and labor-intensive, and it is difficult to maintain production efficiency.

[0005] Therefore, there is an urgent need to provide a cutting device to solve the above problems. UTILITY MODEL CONTENTS

[0032] Further, the shell 11 is provided with a cavity, and the drive piece is arranged in the cavity, and the surface of the shell 11 is free of parts, so that the operator can hold the drive structure 1, and the integrity of the drive structure 1 is good.It should be noted that in the embodiment, the drive structure 1 is an electric grinder pen, which is a commonly used part in the prior art, and is convenient to purchase, and its use process will not be described here.

[0033] Optionally, the output end of the drive unit is connected to the center of the cutter head 21 to drive the rotation of the cutting mechanism around its own center, so that the cutting position of the blade 22 remains unchanged during the cutting process.

[0034] Furthermore, the cutting device also includes a mounting structure 3, a limiting structure 4, and a locking structure (not shown in the figure). The mounting structure 3 is connected to the housing 11. The limiting structure 4 includes a limiting member 41 and an adjusting member 42.

In the first direction, the distance between the other end of the limiting member 41 and the rotation axis of the cutting structure 2 is greater than the radius of the cutter head 21. By abutting the limiting member 41 against the workpiece to be cut and moving the adjusting member 42, and then locking the position of the adjusting member 42 on the mounting structure 3 using the locking structure, different fixed positions of the adjusting member 42 and the mounting structure 3 are achieved.

In other embodiments, the locking structure includes a fixing pin and two or more slots. The fixing pin is slidably connected to the mounting structure 3 and is detachably inserted into the slots. Two or more slots are spaced apart on the adjusting member 42 along the first direction.

By arranging the extension piece 43 connected with the limiting piece 41, the point at which the limiting piece 41 abuts against the to-be-cut piece is increased to a surface at which the extension piece 43 and the limiting piece 41 both abut against the to-be-cut piece, so as to avoid the to-be-cut piece from moving relative to the cutting structure 2, thereby losing the control of the cutting depth of the to-be-cut piece, and the relative stability of the cutting structure 2 and the to-be-cut piece is further improved, and the stability of the control of the cutting depth is further improved.

[0037] Optionally, the limiting structure 4 further comprises a connecting piece 44, the limiting piece 41 and the adjusting piece 42 are connected through the connecting piece 44, so that the connection between the adjusting piece 42 and the limiting piece 41 is more stable, and the integrity of the entire limiting structure 4 is better. In the embodiment, the adjusting piece 42 is fixedly connected with the connecting piece 44, and in other embodiments, the adjusting piece 42 is threadedly connected with the connecting piece 44.

[0038] Further, the number of the limiting pieces 41 is at least two, the number of the extension pieces 43 is at least two, the at least two extension pieces 43 correspond to the at least two limiting pieces 41 one by one, and the at least two extension pieces 43 abut against the to-be-cut piece, so as to further improve the fixing stability of the to-be-cut piece. In other embodiments, the at least two extension pieces 43 can be connected to the same limiting piece 41, or one extension piece 43 can be connected with the at least two limiting pieces 41. In the embodiment, the number of the limiting pieces 41 is two, and in other embodiments, the number of the limiting pieces 41 is three, four or five, etc.

[0039] Optionally, the number of the adjusting pieces 42 is at least two, the number of the locking structures is at least two, the at least two adjusting pieces 42 correspond to the at least two locking structures one by one, and the at least two adjusting pieces 42 are arranged on both sides of the cutter head 21, so as to prevent the fixing positions of the limiting pieces 41 on both sides of the cutter head 21 from being different, thereby causing the cutting depths to be different. The arrangement of the adjusting pieces 42 and the locking structures on both sides of the cutter head 21 makes the limiting adjustment of the limiting mechanism more stable. In the embodiment, the number of the adjusting pieces 42 is two, and in other embodiments, the number of the adjusting pieces 42 is three, four or five, etc.

[0040] Optionally, as shown in Figure 2 The cutting structure 2, the mounting structure 3 and the limiting piece 41 are located on the same side of the shell 11, so as to facilitate the observation of the cutting progress by the operator.

[0041] Optionally, as shown in Figure 1As shown, the mounting structure 3 comprises a first mounting piece 31 and a second mounting piece 32, the first mounting piece 31 is provided with a first through slot, the second mounting piece 32 is provided with a second through slot, the first mounting piece 31 is detachably connected with the second mounting piece 32, the slot opening of the first through slot and the slot opening of the second through slot are oppositely arranged, and the inner wall of the first through slot and the inner wall of the second through slot are clamped on the outer wall of the shell 11, thereby realizing the detachable connection between the shell 11 and the mounting structure 3, and further realizing the detachable connection between the driving structure 1 and the mounting structure 3, which is convenient for the maintenance of the driving structure 1 in the subsequent working environment.

[0042] Further, the first mounting piece 31 is provided with a through hole, and the connecting piece 44 is arranged in the through hole, so that the connecting piece 44 moves back and forth in the through hole along the first direction with the adjusting piece 42. Arranging the connecting piece 44 in the through hole avoids arranging the connecting piece 44 on the periphery of the mounting structure 3, which causes the connecting piece 44 to collide with the cutting structure 2, thereby achieving the effect of avoiding collision, and making the cutting device have better integrity.
