Description

Technical Field

[0001] This utility model belongs to the technical field of quick installation auxiliary equipment for gear hobbing, specifically relating to a quick clamping fixture for gear hobbing that can greatly improve the installation speed and accuracy of the gear hobbing shaft while having high working efficiency. Background Technology

[0002] As attached Figure 1 When hobbing the gear hobbing shaft 1 and its hobbing section 11, if there is no tooling, it can only be installed and positioned on the hobbing machine. Each hobbing shaft 1 must be installed and positioned, and each installation and positioning requires calibration with a dial indicator. This calibration work requires high skill from the operator and has very low work efficiency, which cannot meet the needs of mass production.

[0003] To address this, we developed a high-speed hobbing clamping fixture that significantly improves the installation speed and accuracy of hobbing shafts while maintaining high working efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a quick clamping fixture for gear hobbing that can greatly improve the installation speed and accuracy of the gear hobbing shaft while also increasing working efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-clamping fixture for gear hobbing, comprising a main body and a sleeve clamp; the main body has a central through hole; the diameter of the central through hole gradually decreases from top to bottom; the sleeve clamp is disposed above the central through hole; a base is disposed at the lower part of the main body; a ejector pin is disposed on the base; the center line of the ejector pin coincides with the center line of the central through hole; when the sleeve clamp moves downward relative to the central through hole, the sleeve clamp is pressed, thereby clamping the gear hobbing shaft inside the sleeve clamp.

[0006] Preferably, the base is fixedly connected to the sleeve clamp; a hydraulic pull rod is provided at the lower part of the base.

[0007] Preferably, the centerline of the hydraulic pull rod coincides with the centerline of the ejector pin.

[0008] Preferably, the lower part of the central through hole is further provided with a section with a constant hole diameter to ensure the strength of the main body.

[0009] Compared with the prior art, this utility model provides a quick clamping fixture for gear hobbing, which has the following advantages:

[0010] The quick-clamping fixture for gear hobbing described in this utility model facilitates the relative movement of the sleeve clamp and the central through hole of the main body to achieve quick clamping of the gear hobbing shaft. At the same time, it uses the lower ejector pin and the inner wall of the sleeve clamp for positioning. This utility model can greatly improve the installation speed and accuracy of the gear hobbing shaft. In addition, after one calibration, it can be repeatedly produced, resulting in high work efficiency. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 This utility model provides a technical solution: a quick clamping fixture for gear hobbing, including a main body 2 and a sleeve clamp 3; the main body 2 has a central through hole 21; the diameter of the central through hole 21 gradually decreases from top to bottom; in this embodiment, the lower part of the central through hole 21 is also provided with a section with a constant diameter to ensure the strength of the main body 2; the sleeve clamp 3 is located on the upper part of the central through hole 21; the lower part of the main body 2 is provided with a base 4; a pin 5 is provided on the base 4; the base 4 is fixedly connected to the sleeve clamp 3; a hydraulic pull rod 6 is provided on the lower part of the base 4; the center line of the pin 5, the center line of the sleeve clamp 3, and the center line of the central through hole 21 coincide; when the sleeve clamp 3 moves downward relative to the central through hole 21, the sleeve clamp 3 is pressed, thereby clamping the gear hobbing shaft 1 inside the sleeve clamp 3.

[0016] In this embodiment, the centerline of the hydraulic lever 6 coincides with the centerline of the ejector pin 5.

[0017] In use, the main body 2 is vertically fixed on the workbench. After calibration, the hobbing shaft 1 is inserted into the open sleeve clamp 3, exposing the hobbing part 11. The lower part of the hobbing shaft 1 is held in place by the ejector pin 5. At this time, the hydraulic device is activated and the hydraulic rod 6 is pulled down, which moves the sleeve clamp 3 downward relative to the central through hole 21. The sleeve clamp 3 is then pressed, thereby clamping the hobbing shaft 1 inside the sleeve clamp 3. This allows for quick installation and positioning of the hobbing shaft 1, and the hobbing part 11 can be hobbed immediately upon startup, greatly improving installation speed and accuracy. Furthermore, subsequent installations of the hobbing shaft 1 do not require calibration of the main body 2, avoiding repeated calibration, resulting in high work efficiency and significantly reduced requirements for operators.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The quick clamping fixture for gear hobbing described in this utility model facilitates the relative movement of the sleeve clamp 3 and the central through hole 21 of the main body 2 to quickly clamp the gear hobbing shaft 1. At the same time, it uses the lower ejector pin 5 and the inner wall of the sleeve clamp 3 for positioning. This utility model can greatly improve the installation speed and accuracy of the gear hobbing shaft 1. In addition, after one calibration, it can be repeatedly produced, resulting in high work efficiency.
