Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 - Figure 3The utility model provides an embodiment: a gear tooth density detection device, including a support platform 1 for supporting the overall device, a support plate 3 is fixedly connected to the upper surface of the support platform 1, a scale plate 5 is fixedly connected to the upper surface of the support platform 1, and a scale is marked on the upper surface of the scale plate 5. The scale is symmetrically distributed front and back with the center line of the support plate 3. A counting component is arranged inside the support plate 3. The counting component can accurately measure the number of teeth of the gear body 2. A distance measuring component is arranged on the upper surface of the support platform 1. The distance measuring component has two groups and is symmetrically distributed front and back with the center line of the support platform 1. The distance measuring component can accurately measure the diameter of the gear body 2. The counting component includes a rotating shaft 41. The lower half of the rotating shaft 41 is cylindrical. The rotating shaft 41 A protrusion is provided at the left end of the upper half, and the centers of the gear body 2 and the rotating shaft 41 are on the same vertical line. The gear body 2 is installed on the outer wall of the rotating shaft 41. When the rotating shaft 41 rotates, the gear body 2 will be driven to rotate. The upper surface of the rotating shaft 41 is penetrated by and fixedly connected with a handle 42. The right surface of the handle 42 is provided with a protrusion for easy alignment. Rotating the handle 42 can drive the rotating shaft 41 to rotate. The upper surface of the support plate 3 is penetrated by and slidably connected with a positioning block 43, which slides in the left and right directions. The right surface of the positioning block 43 is penetrated by and threadedly connected with a threaded rod 44. The right surface of the threaded rod 44 is fixedly connected with a turntable 45. A handle is provided on the right surface of the turntable 45 for easy gripping. The handle is located on the right surface of the turntable 45 away from the center of the circle.

[0033] Reference Figure 1 - Figure 3 The counting component also includes an insert block 47. The inner wall of the positioning block 43 is elastically connected to a round rod 46 through a torsion spring 48. A shift block 49 is fixedly connected to the rear surface of the round rod 46. When the round rod 46 rotates, it will drive the shift block 49 to rotate. A rubber pad 411 is fixedly connected to the inner wall of the bottom end of the positioning block 43. When the shift block 49 rotates, it will squeeze the rubber pad 411 to cause the rubber pad 411 to deform. A sensor 412 is fixedly connected to the inner wall of the bottom end of the positioning block 43. The deformed rubber pad 411 squeezes the sensor 412. The sensor 412 is electrically connected to an external counting electronic component. When the squeezing is released, the rubber pad 411 will reset due to its own elasticity, so that the sensor 412 will not be squeezed. At this time, the sensor 412 will count when it is squeezed again, and the data will increase once each time it is squeezed.

[0034] Reference Figure 1 , Figure 4 , Figure 5The distance measuring component includes a slide plate 61, and a clamp plate 64 is penetrated and slidably connected to the rear surface of the slide plate 61. The clamp plate 64 is directly in contact with the gear body 2. A cylindrical protrusion is provided on the front surface of the clamp plate 64, and the protrusion is connected to the slide plate 61. An annular groove 602 is provided at the rear end of the outer wall of the clamp plate 64. A positioning ring 65 is fixedly connected to the inner wall of the top of the slide plate 61. The shape, spacing and size of the annular groove 602 and the positioning ring 65 match. The inner wall of the slide plate 61 is elastically connected to a block 63 through a compression spring 62, and a clamping groove 601 is provided on the right surface of the scale plate 5.

[0035] Reference Figure 1 , Figure 4 , Figure 5 The slide plate 61 is slidably connected to the upper surface of the support platform 1, and the slide plate 61 slides in the front-to-back direction along the upper surface of the support platform 1. The positioning ring 65 is set to a rubber material. When squeezed by an external force, the positioning ring 65 will be deformed. The positioning ring 65 is inserted into the inner wall of the annular groove 602. The rear surface of the block 63 is opened as an inclined surface. When the inclined surface of the block 63 is squeezed, the block 63 will move to the right. The block 63 is set to be L-shaped.

[0036] Reference Figure 1 , Figure 4 , Figure 5 The block 63 passes through and is slidably connected to the left surface of the slide plate 61. The upper surface of the block 63 passes through the upper surface of the slide plate 61. One end of the compression spring 62 is fixedly connected to the right surface of the block 63. The other end of the compression spring 62 is fixedly connected to the inner wall of the right side of the slide plate 61. When the block 63 moves to the right, it will squeeze the compression spring 62 to generate a reaction force. The block 63 is inserted into the inner wall of the slot 601 to limit the slide plate 61.

[0037] Reference Figure 1 - Figure 3 The threaded rod 44 passes through and is rotatably connected to the right surface of the support platform 1. The threaded rod 44 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The threaded rod 44 has a self-locking property. The rotation of the threaded rod 44 can drive the positioning block 43 to slide. The self-locking property of the threaded rod 44 can ensure the stability of the positioning block 43. The rotating shaft 41 passes through and is rotatably connected to the upper surface of the support plate 3.

[0038] Reference Figure 1 - Figure 3 The round rod 46 passes through and is rotatably connected to the upper surface of the positioning block 43. One end of the torsion spring 48 is fixedly connected to the front surface of the round rod 46, and the other end of the round rod 46 is fixedly connected to the inner wall of the front side of the positioning block 43. When the round rod 46 rotates, the torsion spring 48 will be squeezed to generate a reaction force. The right surface of the insert block 47 is fixedly connected to the left surface of the round rod 46. When the insert block 47 is moved, the round rod 46 will be driven to rotate.

[0039] Reference Figure 1 - Figure 3 The left surface of the plug block 47 is set as a slope. When the slope of the plug block 47 is squeezed, the plug block 47 will rotate around the round rod 46. The plug block 47 is clamped with the gear body 2. When the gear body 2 rotates, it will squeeze the plug block 47. The rubber pad 411 is located on the left side of the sensor 412.

[0040] Working principle: When the device is used, first adjust the position of the plug block 47 according to the size of the gear body 2 to be detected. During adjustment, rotate the turntable 45 to drive the threaded rod 44 to rotate, and the rotating threaded rod 44 will drive the positioning block 43 to move to the right. The positioning block 43 moving to the right will drive the round rod 46 and the plug block 47 to move to the right. Similarly, if the round rod 46 and the plug block 47 need to be moved to the left, just rotate the turntable 45 in the opposite direction. When it is adjusted to the appropriate position, stop rotating the turntable 45. The positioning block 43 will be fixed at the current position due to the self-locking property of the threaded rod 44, and the round rod 46 and the plug block 47 will be stabilized.

[0041] Then the gear body 2 is mounted on the rotating shaft 41. At this time, the insert block 47 will be stuck in the gap of the gear body 2 teeth. Then the slide plate 61 is moved toward the center of the support platform 1. During the movement, the inclined surface of the block 63 will be squeezed. The inclined surface of the block 63 will be squeezed and move rightward to squeeze the compression spring 62 to generate a reaction force, and will be separated from the slot 601 to release the limit. When the clamping plate 64 contacts the gear body 2, the slide plate 61 is stopped, and the reaction force of the compression spring 62 will push the block 63 to plug into the nearest slot 601. , limit the compression spring 62, because only one side of the block 63 is a slope, it can play a one-way limiting role, and then rotate the handle 42 to drive the rotating shaft 41 and the gear body 2 to rotate. Since the initial position of the gear body 2 is not the longest point of its diameter, the rotating gear body 2 will squeeze the clamping plate 64 to make the clamping plate 64 retract into the slide plate 61, and the positioning ring 65 will be inserted into the annular groove 602 to limit the clamping plate 64, and then the diameter of the gear body 2 is obtained according to the value on the scale plate 5 that is flush with the clamping plate 64.

[0042] When the gear body 2 rotates, the insert block 47 will be moved, and the insert block 47 will drive the round rod 46 to rotate. The rotating round rod 46 will squeeze the torsion spring 48 to generate a reaction force, and will also drive the shift block 49 to swing and squeeze the rubber pad 411 so that the rubber pad 411 squeezes the sensor 412 to count. When a tooth of the gear body 2 turns over, the squeezing of the insert block 47 will be released, and the reaction force of the torsion spring 48 will drive the insert block 47, the round rod 46 and the shift block 49 to reset, and the rubber pad 411 will also release the squeezing of the sensor 412 due to its own elasticity. After one rotation, the number of teeth of the gear body 2 can be understood according to the value measured by the sensor 412, and then the tooth density can be accurately calculated according to the diameter and the number of teeth.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
