Description

Technical Field

[0001] This utility model relates to the technical field of tool fixing devices, and in particular to a tool fixing device for machining the keyway inside the gearbox of an oil press. Background Technology

[0002] As is well known, the tool fixing device for machining the keyway in the gearbox of an oil press mainly functions to accurately and securely install the tools (such as keyway milling cutters) required for machining the keyway on the power output component of the machining equipment, ensuring that the tools will not loosen, shift, or vibrate during high-speed rotation or feeding.

[0003] However, the tool fixing device used in the traditional oil press gearbox keyway machining equipment usually adopts bolt fastening and other methods. During the machining process, the tool is prone to loosening due to the vibration of the cutting force. Therefore, technical improvement is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a tool fixing device for processing the keyway inside the gearbox of an oil press. When in use, the tool fixing device for processing the keyway inside the gearbox of an oil press uses a synchronous motor to drive the screw to rotate, which in turn drives its threaded sleeve plate and moving rod to move laterally. Subsequently, the push block pushes the slide plate to extend, which can indirectly change the lateral distance between the two main plates and thus change its overall isolation radius to adapt to construction machinery of different sizes.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A tool fixing device for machining the keyway inside the gearbox of an oil press includes a main body. The front end of the outer wall of the main body is fitted with an outer sleeve. A spring is fitted on the outer wall of the outer sleeve. A clamping sleeve is fitted in the middle of the outer wall of the outer sleeve. The outer wall of the clamping sleeve fits against the rear end of the inner wall of the outer sleeve. A main body sleeve is provided on the inner wall of the clamping sleeve. A clamping tongue is fixedly connected to the rear end of the main body sleeve. Multiple springs are provided at the inner edge of the clamping tongue. A round nut is threadedly connected to the front end of the outer sleeve.

[0007] Compared with the existing tool fixing device for machining the internal keyway of the gearbox in an oil press, the tool fixing device for machining the internal keyway of the gearbox in an oil press, through the cooperation of the clamping sleeve and the clamping tongue, combined with the elastic force of the second spring, can form a uniform radial clamping force on the tool, avoiding the problem of force concentration caused by traditional single bolt clamping, reducing the "chatter" or displacement of the tool during high-speed cutting. The sleeve structure of the outer sleeve and the main body, combined with the preload of the first spring, can buffer the axial impact force during the cutting process and enhance the overall rigidity.

[0008] Furthermore, the main body, outer sleeve, and clamping sleeve are all made of 45mm round steel.

[0009] Through the above technical solution, the 45 round steel has high strength, hardness and wear resistance, which can ensure that the device is not easily deformed or damaged when subjected to cutting force, vibration and impact, thereby improving the rigidity and durability of the overall structure.

[0010] Furthermore, the main body sleeve is made of 200r round steel;

[0011] The above technical solution uses 200r round steel to produce materials with high hardness and wear resistance, thereby improving the overall service life.

[0012] Furthermore, the clamping tongue is made of 9GrSi round steel;

[0013] The above technical solution utilizes the high wear resistance of 9CrSi to reduce deformation or wear caused by long-term clamping, ensuring stable clamping accuracy of the tool and avoiding tool loosening caused by wear of the clamping tongue.

[0014] Furthermore, both spring one and spring two are made of steel wire;

[0015] The above technical solution utilizes the excellent elasticity, toughness, and fatigue resistance of steel wire, making it suitable for manufacturing spring-like parts and ensuring that they maintain stable elastic force during long-term compression and rebound.

[0016] Furthermore, the main body sleeve is connected to the rear end thread of the outer wall of the main body by screws;

[0017] The above technical solution allows for easy installation, disassembly, and replacement of the main body sleeve via screws. When the main body sleeve is worn or needs to be adapted to different sizes of cutting tools, it can be quickly repaired or replaced.

[0018] Furthermore, the front end of the spring abuts against the inner wall of the outer sleeve;

[0019] By using the above technical solution, the front end of spring one abuts against the inner wall of the outer sleeve, so that spring one can be in a pre-compressed state, forming a stable axial preload.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model proposes a tool fixing device for machining the internal keyway of the gearbox in an oil press. Compared with existing tool fixing devices for machining the internal keyway of the gearbox in an oil press, this tool fixing device, when in use, uses a clamping sleeve and a clamping tongue in cooperation with the elastic force of spring two to form a uniform radial clamping force on the tool. This avoids the problem of force concentration caused by traditional single bolt clamping, reduces the "chatter" or displacement of the tool during high-speed cutting, and the sleeve structure of the outer sleeve and the main body, combined with the preload of spring one, can buffer the axial impact force during the cutting process and enhance the overall rigidity.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Reference Figure 1-2 An embodiment of this utility model provides a tool fixing device for processing the keyway of the gearbox of an oil press, comprising a main body 1, an outer sleeve 2 sleeved on the front end of the outer wall of the main body 1, a spring 3 sleeved on the outer wall of the outer sleeve 2, a clamping sleeve 4 sleeved in the middle of the outer wall of the outer sleeve 2, the outer wall of the clamping sleeve 4 fitting against the rear end of the inner wall of the outer sleeve 2, a main body sleeve 5 provided on the inner wall of the clamping sleeve 4, a clamping tongue 6 fixedly connected to the rear end of the main body sleeve 5, a plurality of springs 7 provided at the inner edge of the clamping tongue 6, and a round nut threadedly connected to the front end of the outer sleeve 2.

[0028] Compared with existing tool fixing devices for machining keyways in gearboxes of oil presses, this tool fixing device for machining keyways in gearboxes of oil presses, when in use, uses the clamping sleeve 4 and clamping tongue 6 in conjunction with the elastic force of spring 7 to form a uniform radial clamping force on the tool. This avoids the problem of force concentration caused by traditional single bolt clamping, and reduces the "chatter" or displacement of the tool during high-speed cutting. The sleeve structure of the outer sleeve 2 and the main body 1, combined with the preload of spring 3, can buffer the axial impact force during the cutting process and enhance the overall rigidity.

[0029] The main body 1, outer sleeve 2, and clamping sleeve 4 are all made of 45mm round steel.

[0030] The high strength, hardness, and wear resistance of 45 round steel ensure that the device is not easily deformed or damaged when subjected to cutting forces, vibrations, and impacts, thus improving the rigidity and durability of the overall structure.

[0031] The main body sleeve 5 is made of 200r round steel;

[0032] Made from 200r round steel, it has high hardness and wear resistance, thus improving its overall service life.

[0033] The clamping tongue 6 is made of 9GrSi round steel.

[0034] The high wear resistance of 9CrSi can reduce deformation or wear caused by long-term clamping, ensure stable clamping accuracy of the tool, and avoid tool loosening caused by wear of the clamping tongue 6.

[0035] Both spring 1 (3) and spring 2 (7) are made of steel wire;

[0036] Steel wire has good elasticity, toughness and fatigue resistance, making it suitable for making spring-like parts, which can ensure that they maintain a stable elastic force during long-term compression and rebound.

[0037] The main body sleeve 5 is connected to the rear end thread of the outer wall of the main body 1 by screws;

[0038] The main body sleeve 5 is connected to the main body 1 by screws, which facilitates the installation, disassembly and replacement of the main body sleeve 5. When the main body sleeve 5 is worn or needs to be adapted to different specifications of tools, it can be quickly repaired or replaced.

[0039] The front end of spring 3 abuts against the inner wall of outer sleeve 2;

[0040] By having the front end of spring 3 abut against the inner wall of outer sleeve 2, spring 3 can be in a pre-compressed state, forming a stable axial preload.

[0041] Working principle: When in use, first place the tool in the clamping tongue 6, and push the outer sleeve 2 backward by rotating the round nut at the front end of the outer sleeve 2. The outer sleeve 2 drives the clamping sleeve 4 to squeeze the clamping tongue 6. At this time, the spring 7 inside the clamping tongue 6 is compressed by force, and the elastic force forms a uniform radial clamping of the tool. At the same time, the spring 3 at the front end is in a pre-compressed state against the inner wall of the outer sleeve 2, forming an axial preload to buffer the axial impact force during cutting.
