Abstract
Description
Technical Field
[0001] This utility model relates to the field of gear clamps, specifically to a gear internal and external tooth synchronous alignment clamp. Background Technology
[0002] One such Figure 1 The gear shown has internal and external teeth. The upper part has internal and external straight teeth. The internal teeth are machined first. Since multiple lubricating oil holes (6) distributed along the tooth groove need to be machined on the gear circumference, it is necessary to ensure that the tooth groove of the internal tooth and the tooth groove of the external tooth are opposite. When machining the external tooth, the internal tooth needs to be aligned so that the tooth grooves of the internal and external teeth are aligned after machining. Therefore, a fixture for synchronous alignment of the internal and external teeth of the gear needs to be designed. Summary of the Invention
[0003] To address the shortcomings of the existing technology, this utility model provides a gear internal and external gear synchronous alignment fixture, which is easy to clamp and can be used to realize the alignment machining of internal and external gears.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A gear internal and external gear synchronous alignment fixture, characterized in that it includes a base, a fixture base plate, a positioning seat, a gear anti-rotation block, and a pressure plate, wherein the fixture base plate is disposed on the top surface of the base, the positioning seat is disposed in the middle of the top surface of the fixture base plate and has a positioning part in the middle, the gear anti-rotation block is disposed on the top surface of the positioning seat and the axis of symmetry of the gear anti-rotation block is perpendicular to and intersects the axis of the positioning seat, one end of the gear anti-rotation block has a single tooth structure and the other end has a double tooth structure, both of which mesh with the internal gear teeth, and the pressure plate is disposed above the positioning seat for pressing the gear blank onto the fixture base plate.
[0006] Furthermore, a screw is provided at the center of the pressure plate to connect with the positioning seat.
[0007] Furthermore, the anti-rotation block is secured to the positioning seat by screws.
[0008] The advantages of this utility model include: simple structure, convenient clamping, and it can ensure that the external teeth of the gear are aligned with the tooth grooves of the internal teeth after machining. Attached Figure Description

[0011] Figure 3 This is a cross-sectional structural diagram of an embodiment of the present utility model. Detailed Implementation
[0012] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0013] One such Figure 2-3 The gear internal and external gear synchronous alignment fixture shown includes a base 1, a fixture base plate 2, a positioning seat 3, a gear anti-rotation block 4, and a pressure plate 5. The fixture base plate 2 is fixedly mounted on the top surface of the base 1, which determines the installation height for gear clamping. The positioning seat 3 is located in the center of the top surface of the fixture base plate 2, and has a positioning part 31 in the center for center positioning of the smooth inner hole of the gear. The gear anti-rotation block 4 is located on the top surface of the positioning seat 3 and is secured to the positioning seat 3 with screws. The axis of symmetry of the gear anti-rotation block 4 is perpendicular to and intersects the axis of the positioning seat 3. One end of the gear anti-rotation block 4 has a single-tooth structure, and the other end has a double-tooth structure. Both the single-tooth and double-tooth structures mesh with the internal teeth of the gear to limit the circumferential rotation of the gear.
[0014] The pressure plate 5 is positioned above the positioning seat 3 and is used to press the gear blank onto the fixture base plate 2. A screw is located at the center of the pressure plate 5 to connect it to the positioning seat 3.
[0015] The principle of this utility model is to first install the fixture on the gear shaping equipment, and then use the single-tooth or double-tooth structure on the anti-rotation block 4 to align with the gear shaping cutter. After the tool setting is completed, the gear with the machined internal teeth is clamped on the fixture, so that its internal teeth are meshed with the single-tooth and double-tooth structures. This ensures that the root parts of the internal and external teeth are aligned when the external teeth are machined, which is beneficial for the subsequent machining of radially penetrating lubricating oil holes.
[0016] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
