[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0034] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0035] Reference Figures 1-6 As shown, an end gear disk machining positioning fixture includes: a placement disk 101 for placing the end gear disk body 100 and a rotation mechanism 200 for driving the placement disk 101 to rotate to achieve machining of the end gear disk body 100 at various angles;

[0036] The rotating mechanism 200 includes: a rotating component that drives the placement disk 101 to rotate around a vertical axis and a rotating component that drives the placement disk 101 to rotate around a horizontal axis. The placement disk 101 is provided with multiple sets of adjustable spacing limiting mechanisms 300 for limiting the end toothed disk body 100.

[0037] In use, the end gear disc body 100 to be processed is placed on the placement plate 101 of the positioning fixture. Based on the size of the end gear disc body 100 and processing requirements, the spacing of the multiple sets of limiting mechanisms 300 on the placement plate 101 is adjusted to ensure that the end gear disc body 100 is stably limited in the predetermined position. The rotating component in the rotating mechanism 200 is activated, driving the placement plate 101 to rotate around the vertical axis, allowing the end gear disc body 100 to rotate around the vertical axis for processing from different angles. Depending on processing requirements, the rotating component in the rotating mechanism 200 is activated in a timely manner, driving the placement plate 101 to rotate around the horizontal axis to further adjust the processing angle of the end gear disc body 100 and achieve more complex processing requirements. Driven by the rotating mechanism 200, the placement plate 101 can rotate around the vertical and horizontal axes, enabling processing of the end gear disc body 100 at various angles. This design reduces the time spent manually adjusting the workpiece position and improves processing efficiency.

[0038] Reference Figures 2-3 As shown, the rotating component includes: a mounting bracket 204, a rotary motor 205, a driving gear 206, and a driven gear 208; wherein,

[0039] The mounting bracket 204 is vertically rotatably equipped with a drive shaft 207. The placement disk 101 is fixedly mounted on the top of the drive shaft 207. The mounting bracket 204 is fixedly equipped with a rotary motor 205. The output shaft of the rotary motor 205 is vertically upward and is fixedly fitted with a drive gear 206. The drive shaft 207 is fixedly fitted with a driven gear 208 that meshes with the drive gear 206. The mounting bracket 204 is equipped with a rotating component that drives the mounting bracket 204 to rotate around a horizontal axis.

[0040] In the above scheme, when in use, the rotary motor 205 is started, its output shaft starts to rotate and drives the drive gear 206 to rotate. The drive gear 206 meshes with the driven gear 208, thereby driving the driven gear 208 and the drive shaft 207 fixed thereto to rotate. The rotation of the drive shaft 207 drives the placement disk 101 fixed at its top and the end gear disk body 100 placed on it to rotate around the drive shaft 207, so that processing can be performed from different angles.

[0041] Reference Figures 2-3 As shown, the rotating component includes: a bracket 201, a drive motor 202, and a rotating shaft 203; wherein,

[0042] The mounting bracket 204 is rotatably mounted on the support 201 via the rotating shaft 203. The support 201 is fixedly equipped with a drive motor 202. The output shaft of the drive motor 202 is horizontally positioned and its top end is fixedly connected to the rotating shaft 203 via a coupling.

[0043] In the above scheme, when in use, the drive motor 202 starts, and its output shaft begins to rotate. The output shaft of the drive motor 202 drives the rotating shaft 203 to rotate via a coupling. The rotation of the rotating shaft 203 causes the mounting bracket 204 to rotate around the axis of the rotating shaft 203. As the mounting bracket 204 rotates, the placement disk 101 and its end gear disk also adjust their angles, thus allowing processing from different angles. Through the design of the rotating component, the rotation of the placement disk 101 and the end gear disk on the horizontal plane is realized, enhancing the flexibility of processing.

[0044] Reference Figures 4-6 As shown, each set of limiting mechanisms 300 includes: a slider 309, a limiting plate 310, and a moving part; wherein,

[0045] The placement tray 101 has a groove 305 along its diameter direction. A slider 309 is slidably disposed in the groove 305. A limiting plate 310 is fixedly disposed on the upper surface of the slider 309 and contacts the side of the end gear plate body 100. A horizontal limiting groove 311 is also provided on the inner side wall of the groove 305 for the slider 309 to slide. The placement tray 101 is provided with a moving part that drives the slider 309 to slide in the groove 305.

[0046] In the above scheme, the end gear disk body 100 is placed on the placement plate 101. At this time, the limiting plate 310 maintains a certain distance from the side of the end gear disk body 100. The actuating moving component drives the slider 309 to slide within the slide groove 305. Simultaneously, the slider 309 maintains stable horizontal movement under the constraint of the limiting slide groove 311. The sliding of the slider 309 further drives the limiting plate 310 to move closer to the side of the end gear disk body 100 until it reaches the predetermined limiting position. During the processing of the end gear disk body 100, the limiting plate 310 keeps the side of the end gear disk body 100 in a limiting position to prevent it from shaking or moving. According to processing needs, the position of the limiting plate 310 can be adjusted in time to adapt to end gear disk bodies 100 of different sizes or different processing angles.

[0047] Reference Figures 4-6 As shown, the moving component includes: a second gear 304, a rack 306, and a driving component; wherein,

[0048] The placement tray 101 is vertically rotatable with a rotating shaft 303. A second gear 304 is fixedly sleeved on the rotating shaft 303. A rack 306 that meshes with the second gear 304 is slidably provided on the inner top wall of the placement tray 101. The slider 309 is fixedly mounted on the rack 306. The placement tray 101 is provided with a driving component that drives the rotating shaft 303 to rotate.

[0049] In the above scheme, according to the processing needs, the driving component is started to drive the rotating shaft 303 to rotate. The second gear 304 on the rotating shaft 303 rotates together with the rotating shaft 303, meshes with the rack 306 and drives it to slide in the horizontal direction. The sliding of the rack 306 causes the slider 309 to slide in the slide groove 305, thereby causing the limiting plate 310 to move closer to or away from the side of the end gear plate body 100, so as to achieve the purpose of adjusting the limiting position.

[0050] Reference Figures 5-6 As shown, the driving component includes: a gear ring 301, a first gear 302, and a driving gear 308; wherein,

[0051] A gear ring 301 is rotatably mounted inside the placement disk 101. A first gear 302, which is parallel to the second gear 304 and meshes with the gear ring 301, is fixedly mounted on the rotating shaft 303. A motor 307 is fixedly mounted on the inner bottom wall of the placement disk 101. The output shaft of the motor 307 is vertically upward and a drive gear 308 that meshes with the gear ring 301 is fixedly mounted on it.

[0052] In use, the motor 307 is started, and its output shaft begins to rotate. The drive gear 308 fixed on the output shaft of the motor 307 rotates accordingly, meshing with the gear ring 301 and driving it to rotate. The rotation of the gear ring 301 drives the first gear 302 meshing with it to rotate. The first gear 302 is fixedly connected to the rotating shaft 303, so the rotating shaft 303 also rotates. The second gear 304 on the rotating shaft 303 rotates together with the rotating shaft 303, and then meshes with the rack 306 and drives it to slide. The sliding of the rack 306 causes the slider 309 and the limiting plate 310 to move, thereby adjusting the limiting position of the opposite end gear plate body 100.

[0053] Reference Figures 3-4 As shown, the limiting plate 310 is provided with a fixing component 400 for fixing the end toothed disc body 100 placed on the placement plate 101.

[0054] In the above solution, the fixing component 400 can firmly fix the end gear plate body 100 on the placement plate 101 to prevent it from shaking or moving during the processing, thereby improving the processing accuracy. By fixing the end gear plate body 100 with the fixing component 400, safety accidents caused by shaking or moving of the end gear plate body 100 during the processing can be avoided.

[0055] Reference Figure 4 and Figure 6As shown, the fixing component 400 includes: a fixing plate 402 and a screw 403; the screw 403 is threaded through the limiting plate 310, and the fixing plate 402 is rotatably mounted on the bottom surface of the screw 403 and contacts the surface of the end gear plate body 100. The limiting plate 310 has a limiting groove 401 on its side for the fixing plate 402 to slide.

[0056] In the above scheme, the end gear plate body 100 is placed on the placement plate 101, and the screw 403 is rotated. As the screw 403 rotates, the fixing plate 402 is pushed or pulled by the screw 403, slides in the limiting groove 401, and gradually approaches or moves away from the surface of the end gear plate body 100. When the fixing plate 402 contacts the surface of the end gear plate body 100, the screw 403 is rotated again, so that the fixing plate 402 applies a certain pressure to the end gear plate body 100 and fixes it on the placement plate 101. During the processing, the fixing plate 402 maintains a fixed state on the end gear plate body 100 to prevent it from shaking or moving.

[0057] Reference Figure 6 As shown, a handle 404 is fixedly provided at the top end of the screw 403.

[0058] In the above solution, the design of the handle 404 allows the worker to directly hold and rotate the screw 403 without using additional tools, which improves the convenience of operation. The position of the fixing plate 402 can be adjusted by directly rotating the handle 404, saving the time of using tools and reducing the processing cost.

[0059] In summary, the end gear disc machining positioning fixture provided by this utility model, when in use, places the end gear disc body 100 to be machined on the placement plate 101, starts the motor 307 inside the placement plate 101, and the output shaft of the motor 307 drives the drive gear 308 to rotate. Since the drive gear 308 meshes with the gear ring 301, the gear ring 301 rotates accordingly. The rotation of the gear ring 301 is transmitted to the rotating shaft 303 through the first gear 302, and the second gear 304 on the rotating shaft 303 rotates accordingly. Since the second gear 304 meshes with the rack 306, the rack 306 slides horizontally within the placement plate 101. The sliding of the rack 306 drives the slider 309 to move within the slide groove 305, thereby driving the limiting plate 310 to move closer to the end gear disc body 100. According to the size and shape of the end gear plate body 100, adjust the position of the limiting plate 310 to appropriately limit the end gear plate body 100. After the limiting plate 310 is adjusted to the appropriate position, rotate the screw 403 on the limiting plate 310. Since the screw 403 is threaded through the limiting plate 310 and rotatably assembled with the fixing plate 402, rotating the screw 403 will cause the fixing plate 402 to move downward and make close contact with the surface of the end gear plate body 100. The fixing plate 402 slides in the limiting groove 401 to ensure its stability during movement. Continue to rotate the screw 403 until the fixing plate 402 firmly fixes the end gear plate body 100 on the placement plate 101. Depending on the processing requirements, it may be necessary to adjust the orientation of the end gear plate body 100. At this time, start the drive motor 202 on the bracket 201. Its output shaft is connected to the rotating shaft 203 through the shaft coupling, driving the mounting bracket 204 to rotate around the horizontal axis. After the mounting bracket 204 rotates to the predetermined angle, start the rotary motor 205. The output shaft of the rotary motor 205 drives the drive gear 206 to rotate. Since the drive gear 206 meshes with the driven gear 208, the driven gear 208 rotates around the vertical axis. Through the cooperation of the two rotating parts, the placement disk 101 can be rotated and adjusted at any angle. After the end gear disk body 100 is adjusted to a suitable processing position, the processing equipment is started to process the end gear disk body 100.

[0060] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0061] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
