Description

Technical Field

[0001] The utility model relates to the field of scraping knives, in particular to an electric scraping knife. Background Technique

[0002] An electric scraping knife is an electric scraping tool suitable for scraping harder materials. It is applicable to scraping and processing of machine tool guide surfaces, sealing mating surfaces of mechanical equipment, flat plates, planes, etc., and can replace traditional manual scraping, which is more labor-saving.

[0003] However, the existing electric scraping knives can only move back and forth in the extending and shortening directions. They scrape the machine tool guide surface by the forward impact of the scraping knife. However, the scraping area is relatively small and the flexibility is relatively insufficient. Therefore, the utility model provides an electric scraping knife. Content of the Utility Model

[0004] The purpose of the utility model is to provide an electric scraping knife to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] An electric scraping knife includes a housing and a rotatable rotating assembly, an adjusting assembly and a scraping knife assembly arranged inside the housing, wherein the scraping knife assembly extends out from the end of the housing; the adjusting assembly and the scraping knife assembly are fixedly connected, the rotating assembly is inserted into the adjusting assembly, and the adjusting assembly is driven by the rotating assembly to drive the scraping knife assembly to move horizontally and vertically;

[0007] The adjusting assembly includes a moving part with a hollow middle part in the vertical direction and a bearing. The bearing is installed at the end of the moving part, and the scraping knife assembly is fixedly connected to the end of the moving part connected to the bearing;

[0008] The rotating assembly includes a turntable, rotating rods fixedly connected to both ends of the turntable and a rotating shaft; the rotating shaft is eccentrically connected to the turntable and is inserted into the hollow part of the moving part. By eccentric rotation, the rotating shaft can drive the moving part to move longitudinally in a direction perpendicular to the rotating shaft;

[0009] The width of the turntable is an uneven width with a gradually changing distance, and the outer wall of the bearing is in contact with the side surface of the turntable near the outer wall. As the turntable rotates, the distance between the bearing and the rotating rod changes accordingly, so as to realize the horizontal movement of the bearing.

[0010] Preferably, connecting rods extend from the end of the moving part and the bearing for fixedly connecting to the middle of the bearing. There is a distance between the end of the moving part close to the bearing and the bearing for connecting the scraping knife assembly.

[0011] Preferably, the scraper blade assembly includes a scraper blade body and a connecting portion. One end of the connecting portion is fixedly connected to one end of the scraper blade body, and the other end is hollowed out in the middle horizontally. The bearing is located at the hollowed-out portion; the connecting rod passes through the middle vertically of the connecting portion and is fixedly connected; the other end of the scraper blade body extends to the outside of the housing.

[0012] Preferably, the width distance between the turntable and the bearing in contact is cyclically and alternately changed through two cycles of increasing to decreasing and decreasing to increasing. When the width distance of the turntable is in the increasing-to-decreasing cycle, the scraper blade assembly can move toward the rotating rod direction following the rotation of the turntable; when the width distance of the turntable is in the decreasing-to-increasing cycle, the turntable drives the scraper blade assembly to move away from the rotating rod.

[0013] Preferably, the rotating assembly further includes a driving structure fixedly connected to the end of the rotating rod away from the turntable to drive the rotating rod to rotate.

[0014] Preferably, a rotating shaft protrudes from the middle of the end of the turntable close to the moving portion. The rotating shaft is fixedly connected to the rotating rod, and the rotating rod is connected at a non-central position of the rotating shaft.

[0015] Preferably, the outer wall of the rotating rod contacts the inner wall of the hollowed-out portion of the connecting portion; the hollowed-out width of the moving portion is greater than the diameter of the rotating rod.

[0016] Preferably, the moving portion is preferably cylindrical with a circular cross-section.

[0017] Preferably, a nut is bolted to the end of the rotating rod away from the turntable to prevent the moving portion from disengaging from the rotating rod during lateral movement.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] The structure of the present utility model is simple. The rotating rod is inserted into the moving portion, and through the eccentric connection of the rotating rod, the moving portion follows the eccentric rotation of the rotating rod, thereby realizing the longitudinal movement of the moving portion, which can drive the scraper blade assembly to perform longitudinal movement. That is, in addition to the scraper blade assembly being able to extend out of the housing for front and back impacts, it can also move left and right, greatly improving the flexibility of the scraper blade and the scraping area.

[0020] At the same time, the width distance of the turntable is a gradually changing unequal-width distance, and the width distance is alternately changed through increasing to decreasing and decreasing to increasing. The turntable contacts the outer wall of the bearing connected to the end of the moving portion. As the turntable rotates, it can make the bearing drive the rotating assembly to change accordingly, realizing the lateral movement of the scraper blade assembly, and can be carried out before and after the left and right movement of the scraper blade assembly, with higher flexibility and a relatively larger scraping area.

Detailed implementation mode Embodiment 1

[0027] Please refer to Figures 1-4 , the present utility model provides a technical solution: an electric shovel flower knife, including a housing 1 and a rotatable rotating component 2, adjusting component 3 and shovel blade component 4 arranged inside the housing 1, wherein the shovel blade component 4 extends out from the end of the housing 1; the adjusting component 3 and the shovel blade component 4 are fixedly connected, the rotating component 2 is inserted into the adjusting component 3, and the rotation of the rotating component 2 drives the adjusting component 3 to move horizontally and vertically, so as to drive the shovel blade component 4 to move horizontally and longitudinally;

[0028] The adjusting component 3 includes a moving part 31 and a bearing 32. The middle part of the moving part 31 is hollowed out vertically, and the width of the hollowed out part extends to both sides. A connecting rod extends from the end of the moving part 31 for fixedly connecting with the middle part of the bearing 32. There is a certain distance between the bearing 32 and the end of the moving part 31 for fixedly connecting with the shovel blade component 4; the shovel blade component 4 includes a shovel blade main body 41 and a connecting part 42. One end of the connecting part 42 is fixedly connected with one end of the shovel blade main body 41, and the other end is hollowed out in the middle horizontally. The bearing 32 is located at the hollowed out part; the connecting rod passes through the middle part of the connecting part 42 vertically and is fixedly connected; the other end of the shovel blade main body 41 extends to the outside of the housing 1;

[0029] The rotating assembly 2 includes a rotating rod 21, a rotating disc 22, and a rotating bar 23. One end of the rotating disc 22 is fixedly connected to the rotating rod 21, and the other end protrudes with a rotating shaft 221 for fixedly connecting to the rotating bar 23. The rotating bar 23 is not connected to the center of the rotating shaft 221, realizing an eccentric connection. Thus, the rotation of the rotating shaft 221 drives the rotating bar 23 to achieve eccentric rotation; the rotating bar 23 is inserted into the hollow part of the moving part 31, and the outer wall of the rotating bar 23 contacts the inner wall of the hollow part. When the rotating bar 23 performs eccentric rotation, it can drive the moving part 31 to perform longitudinal movement in the direction perpendicular to the rotating bar 23, thereby driving the longitudinal movement of the connecting part 42 and the cutter body 41; the moving part 31 preferably has a cylindrical cross-section; the rotating assembly 2 further includes a driving structure, and the driving structure is fixedly connected to the end of the rotating rod 21 away from the rotating disc 22 to drive the rotation of the rotating rod 21;

[0030] The width distance of the rotating disc 22 is a gradually changing unequal-width distance (see Figure 3 ), and the outer wall of the bearing 32 remains in contact with the side surface of the rotating disc 22 near the outer wall. As the rotating disc 22 rotates, the width distance of the contact between the rotating disc 22 and the bearing 32 changes alternately in two cycles of increasing to decreasing and decreasing to increasing. When the width distance of the contact between the rotating disc 22 and the bearing 32 is in the cycle of decreasing to increasing, the rotating disc 22 will push the bearing 32 to move away from the rotating disc 22, and the bearing 32 simultaneously drives the moving part 31 and the cutter assembly 4 to move. When the width distance of the contact between the rotating disc 22 and the bearing 32 is in the cycle of increasing to decreasing, the cutter assembly 4 can push the bearing 32 and the moving part 31 to move towards the rotating disc 22, so that the rotating disc 22 and the bearing 32 always remain in contact, thereby realizing the lateral movement of the cutter assembly 4; therefore, when the rotating disc 22 rotates, the cutter assembly 4 can simultaneously realize lateral movement and longitudinal movement. Embodiment 2

[0031] Based on Embodiment 1, as Figure 5 shown, a nut 24 is bolted to the end of the rotating bar 23 away from the rotating disc 22 to prevent the moving part 31 from detaching from the rotating bar 23 during lateral movement.
