Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, and particularly relates to an involute gear generating instrument. Background Art

[0002] The involute gear generating instrument plays an important role in the courses of mechanical principle (basic mechanical design) and the field of gear processing. By simulating the motion relationship and cutting process between the tool and the blank, people can intuitively observe the formation process of the involute tooth profile, which helps students deeply understand how the profile of the involute gear is formed through the cutting motion of the tool.

[0003] In the prior art, when students use the involute gear generating instrument, they need to manually move the rack cutter every time they draw. If the movement is not uniform enough, the aesthetics of the drawn gear will decline. If the movement distance is too large, students cannot completely draw the gear tooth shape, resulting in the inability to observe the undercut phenomenon. If the movement distance is too small, the drawn gear will be too dense, which wastes the learning time of students. Summary of the Utility Model

A first threaded block 106 is arranged in the limiting groove 105, and the first threaded block 106 is threadedly connected to the inner surface of the connecting plate 103.

[0034] Among them, the area of the end of the first threaded block 106 is larger than the area of the limiting groove 105. The user can adjust the position of the toothed knife 104 by loosening the first threaded block 106 and fix the position of the toothed knife 104 by tightening the first threaded block 106.

[0035] Preferably, the bearing component 100 further includes a rack 107 fixedly connected to one surface of the connecting plate 103. One surface of the support plate 101 is fixedly connected with a gear disc 108 through a bearing.

[0036] Among them, the teeth of the rack 107 mesh with the teeth of the gear disc 108. A certain gap is left between the toothed knife 104 and the tray 109. The user can place the drawing on the surface of the tray 109 by removing the second threaded block 110, and then fix the drawing by tightening the second threaded block 110.

[0037] During use, loosen the second threaded block 110, remove the second threaded block 110, place the drawing on the surface of the tray 109, then tighten the second threaded block 110 to fix the drawing.

[0039] Embodiment 2

[0040] Referring to Figure 3 and Figure 4 , this is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides the structure of the driving component 200 and an operation method for keeping the moving distance of the rack consistent each time.

[0041] Specifically, the driving component 200 further includes a first bevel gear 203 fixedly installed at the output end of the motor 202. The inner surface of the support plate 101 is fixedly connected with a coupling 204 through a bearing. One end of the coupling 204 penetrates to one side surface of the support plate 101 and is fixedly connected with one side surface of the gear disk 108. The other end of the coupling 204 penetrates to the other side of the inner surface of the sheet metal part 201.

[0042] Among them, the motor 202 is used to drive the first bevel gear 203 to rotate synchronously.

[0043] Furthermore, the driving component 200 further includes a second bevel gear 205 fixedly installed at the other end of the coupling 204. The number of teeth of the second bevel gear 205 is the same as that of the first bevel gear 203.

[0044] Among them, the teeth of the first bevel gear 203 mesh with the teeth of the second bevel gear 205. The second bevel gear 205 can reduce the rotation of the first bevel gear 203 and then transmit it to the coupling 204.

[0045] Preferably, the driving component 200 further includes a driving button 206 adaptively installed on one side surface of the sheet metal part 201. A camera 207 is fixedly installed on one side surface of the tray 109.

[0046] Among them, pressing the driving button 206 can make the output end of the motor 202 rotate a fixed number of turns. Each time the driving button 206 is pressed, the camera 207 will record for a period of time, and the video will be transmitted to the remote terminal through the app, so as to achieve the effect of supervising each student to independently complete the homework after class.

[0047] In use, press the drive button 206 to make the output end of the motor 202 drive the first bevel gear 203 to rotate a fixed number of turns. Then, through the cooperation of the first bevel gear 203 and the second bevel gear 205, the second bevel gear 205 decelerates the rotation of the first bevel gear 203 and transmits it to the coupling 204. While the coupling 204 drives the tray 109 and the drawing paper to rotate a fixed number of turns through the gear disk 108, through the cooperation of the rotation of the gear disk 108 and the rack 107, the tooth cutter 104 is driven to move a fixed distance, so as to effectively ensure that the moving distance of the rack each time remains the same, making the gears drawn by students on the paper more uniform and aesthetic. Each time the drive button 206 is pressed, the camera 207 records for a period of time, and the video is transmitted to the remote terminal through the app, so as to achieve the effect of supervising each student to complete the homework independently after class.

[0048] In summary, through the cooperation between the components in the drive assembly 200, it can effectively ensure that the moving distance of the rack 107 remains the same each time, so that the gears drawn by students on the paper are more uniform and aesthetic, so as to achieve the effect that students can completely observe the gear processing process and undercut phenomenon. At the same time, it can also supervise the situation of each student completing the homework independently after class.
