Description

Technical Field

[0001] The utility model relates to the technical field of gears, in particular to a gear shaft end face and inner hole detection device. Background Art

[0002] As is known to all, gears refer to mechanical elements with gears on the wheel rim that continuously mesh to transmit motion and power. The transmission between gears is a mechanical transmission that utilizes the mutual meshing of the gear teeth of the two gears to transmit power and motion. According to the relative position of the gear axes, they are divided into parallel axis cylindrical gear transmission, intersecting axis bevel gear transmission and staggered axis helical gear transmission. They have the characteristics of compact structure, high efficiency and long service life.

[0003] Among all mechanical transmissions, gear transmission is the most widely used and has an accurate instantaneous transmission ratio. Secondly, after the gear is produced, its end face and inner hole values ​​will be tested by a gear testing device to determine whether they meet the standard values, making it more accurate in subsequent meshing movement.

[0004] During the inspection process of the gear detection device, it is necessary to first fix it on the table of the detection device. However, the fixing parts on the detection device can usually only fix gears of one specification, and cannot fix gears of different specifications. As a result, the detection device can only detect gear parts of the same specification, which brings certain shortcomings to the gear detection device. Utility Model Content

[0005] In view of the above problems existing in the prior art, one aspect of the present invention is to provide a gear shaft end face and inner hole detection device to solve the above deficiencies of the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a gear shaft end face and inner hole detection device, including a workbench and a detection table, and also includes: a fixed plate, which is arranged on the detection table; at least three fixed protrusions are slidably arranged in the circumferential direction of the fixed plate; an adjusting rod, which is connected to the fixed plate, and a connecting plate is connected to the adjusting rod; each of the fixed protrusions is hinged to the connecting plate through a connecting rod.

[0007] Preferably, a plurality of second through slots are formed in the circumferential direction of the fixed disk, and each of the second through slots is a rectangular structure.

[0008] Preferably, a slide rail is provided in each of the second through grooves.

[0009] Preferably, each of the fixed protruding rods is provided with a sliding seat that slidably cooperates with each of the sliding rails.

[0010] Preferably, a detector is also provided on the detection platform.

[0011] Preferably, a detection pointer is provided on the detector.

[0012] Preferably, when the adjusting rod descends, the connecting disk causes the fixing protrusions to retract toward the center of the fixing disk through the connecting rods.

[0013] In the above technical scheme, a gear shaft end face and inner hole detection device provided by the utility model has the following beneficial effects: when it is necessary to detect gears of other specifications, the utility model can rotate the adjusting rod to make it descend through threaded transmission with the fixed disk. During the descending process of the adjusting rod, it links the fixed convex rod through the connecting rod hinged on the connecting disk, forcing it to move toward the center of the fixed disk, thereby reducing the diameter of the circle between the three fixed convex rods, that is, it can adapt to gears of other specifications. The device adapts to gears of different specifications by adjusting the size of the center diameter of the circle between the fixed convex rods, so that gears of different specifications can be fixed for detection, weakening or even avoiding the problem that gears of different specifications cannot be fixed, resulting in the detection device being able to detect gear parts of the same specification, which brings certain shortcomings to the gear detection device.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] See also Figure 1-5 The gear shaft end face and inner hole detection device is used to solve the problem that during the detection process of the gear detection device, it is necessary to first fix it on the table of the detection device, and the fixing parts on the detection device can usually only fix gears of one specification, and cannot fix gears of different specifications, resulting in the detection device being able to only detect gear parts of the same specification, which brings certain deficiencies to the gear detection device.

[0024] As a further technical solution proposed by the present invention, the workbench 1 and the testing table 2 are further provided, and also include: a fixed plate 5, which is arranged on the testing table 2; at least three fixed protruding rods 6 are slidably arranged on the circumference of the fixed plate 5; an adjusting rod 7, which is connected to the fixed plate 5, and a connecting plate 7.1 is connected to the adjusting rod 7; each fixed protruding rod 6 is hinged to the connecting plate 7.1 through a connecting rod 6.2, and further, the adjusting rod 7 is connected to the fixed plate 5 through a thread, such as Figure 2 As shown in the state, the adjusting rod 7 is rotatably connected with the connecting disk 7.1, so that the adjusting rod 7 and the fixed disk 5 do not interfere with each other when the threaded transmission descends. Specifically, when it is necessary to detect gears of other specifications, the adjusting rod 7 is rotated to make it descend with the threaded transmission of the fixed disk 5. During the descent of the adjusting rod 7, it is linked with the fixed protruding rod 6 through the connecting rod 6.2 hinged on the connecting disk 7.1, forcing it to move toward the center of the fixed disk 5, so that the circle diameter between the three fixed protruding rods 6 is reduced (and vice versa), that is, it can adapt to gears of other specifications. The device adapts to gears of different specifications by adjusting the center diameter size between the fixed protruding rods, so that gears of different specifications can be fixed for detection, which weakens or even avoids the problem that it is impossible to fix gears of different specifications, resulting in the detection device being able to detect gear parts of the same specification, which brings certain shortcomings to the gear detection device.

[0025] In another embodiment of the utility model, at least three first through slots 2.1 are provided on the workbench 1, which facilitate each connecting rod 6.2 to pass through and connect with the connecting plate 7.1. Figure 3 Status shown.

[0026] In another embodiment of the utility model, a plurality of second through grooves 5.1 are opened on the circumference of the fixed disk 5, and each second through groove 5.1 is specifically a rectangular structure. Furthermore, the second through groove 5.1 is used to place a fixed protruding rod 6, which is used to fix the gear for subsequent detection. The fixed protruding rod 6 is adapted to the opening on the detection gear, and the two are snap-fitted for installation before subsequent detection work is carried out. This is the prior art and will not be described in detail.

[0027] In another embodiment of the utility model, preferably, each second through groove 5.1 is provided with a slide rail 5.2, and each fixed protrusion 6 is provided with a slide seat 6.1 that slidably cooperates with each slide rail 5.2. Furthermore, the slide rail 5.2 provided in each second through groove 5.1 is used to slidably cooperate with the slide seat 6.1 to improve the stability and smoothness of the fixed protrusion 6 during sliding adjustment.

[0028] In another embodiment of the present invention, a detector 3 is further provided on the detection platform 2, and a detection pointer 4 is provided on the detector 3. Figure 1 As shown in the state, the detector 3 and the detection pointer 4 are used to detect the values ​​of the end face and the inner hole of the gear to determine whether they meet the standard values. This is the existing technology and will not be described in detail.

[0029] In another embodiment of the utility model, preferably, when the adjusting rod 7 descends, the connecting disk 7.1 causes each fixed convex rod 6 to retract toward the center of the fixed disk 5 through each connecting rod 6.2. When the adjusting rod 7 descends, the connecting rod 6.2 drives the fixed convex rod 6 to move toward the center of the fixed disk 5, thereby adjusting the center diameter size between each fixed convex rod 6, and when the adjusting rod 7 rises, the center diameter size between each fixed convex rod 6 is expanded. That is, the device can adapt to gears with different center diameter sizes by adjusting the size of the center of the circle between the fixed convex rods 6, so that gears of different specifications can be fixedly mounted on the testing table 2 for testing.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
