Description

Milling cutter disassembly tool

This creation is related to the milling cutter of the horizontal milling machine, or more specifically, a tool for disassembling and assembling the milling cutter.

As shown in the first figure, the milling cutter 1 of the known horizontal milling machine is set on the spindle 2 and opposite to the worktable, and the milling cutter 1 is fixed to the spindle 2 by a fixing assembly 3. The fixing assembly 3 includes a plurality of sleeves 4 and an end sleeve 5. Each sleeve 4 is successively sleeved on the spindle 2 to abut and fix the milling cutter 1. The end sleeve 5 is locked at the end of the spindle 2 (the end of the spindle 2 is provided with a thread) to fix each sleeve 4. As shown in the second figure, a clamping part 6 is provided at the end of the end sleeve 5, which is composed of two receiving surfaces 7 facing each other.

Since the end sleeves 5 are not common nut components, there are no suitable disassembly tools for disassembly and assembly. Therefore, when a worker wants to disassemble and assemble a milling cutter, he usually uses a conventional adjustable spanner with an adjustable opening width to disassemble and assemble the end sleeve 5. The method is to clamp the two receiving surfaces 7 of the end sleeve 5 with two jaws of the adjustable spanner, and then apply force to the adjustable spanner to rotate the end sleeve 5 and disassemble and assemble the end sleeve 5. Since the end sleeve 5 must be locked to prevent the milling cutter position from changing and affecting the machining accuracy of the workpiece, it is very difficult to simply use an adjustable wrench to apply force to disassemble or lock the end sleeve 5. Therefore, it is known that most workers will use an iron pipe to plug the handle of the adjustable wrench to facilitate force application. This method is very inconvenient and laborious. In addition, the two jaws of the adjustable wrench are easily loosened during the process of applying force to rotate the end sleeve 5, resulting in the need to re-clamp the end sleeve 5 with the two jaws of the adjustable wrench, which is very time-consuming and inconvenient.

Therefore, the creator created this "Milling Cutter Disassembly Tool" based on many years of innovative research and development and processing experience, which can solve the above-mentioned deficiencies.

The main purpose of this invention is to provide a milling cutter disassembly and assembly tool, which is convenient for connecting a tool to disassemble or lock the end sleeve, and easily completes the disassembly and installation of the milling cutter. It is more time-saving and labor-saving in operation, and has great practical value.

Therefore, in order to achieve the above-mentioned purpose, this invention provides a milling cutter disassembly tool, the milling cutter is set on a spindle of a horizontal milling machine and fixed by a fixing assembly, the fixing assembly includes a plurality of sleeves and an end sleeve, each sleeve is successively sleeved on the spindle to abut the milling cutter, the end sleeve is locked on the end of the spindle to fix each sleeve, and a clamping part is provided at the end thereof. The disassembly tool is used to disassemble or lock the end sleeve, one end of which is provided with a sleeve part and the other end is provided with a plug-in part, the sleeve part is complementary to the shape of the clamp part, and is used to make the sleeve part sleeved on the outside of the clamp part.

Preferably, the sleeve portion includes a recess and two clamping surfaces disposed opposite to the inner side of the recess. The recess can be sleeved on one end of the end sleeve to cover the clamping portion. The two clamping surfaces complement the shape of the clamping portion.

Preferably, the depth of the recess is greater than the distance that the clamping portion extends along the axial direction of the end sleeve.

Preferably, the cross-section of the recess and the end sleeve is circular.

Preferably, the clamping portion includes two opposite receiving surfaces, and the two clamping surfaces complementarily abut against the two receiving surfaces.

Preferably, the plug-in portion includes a receiving hole, and two clamping holes are relatively recessed inside the receiving hole. The receiving hole is for inserting a connecting block provided at one end of the tool, and the two clamping holes are for elastic clamping of two steel balls provided at two sides of the connecting block.

Below, we will cite a preferred embodiment of this creation and provide a further detailed description with diagrams, including:

First, please refer to the second to fourth figures, which are a disassembly tool 10 of a milling cutter 1 of a preferred embodiment of the present invention. The milling cutter 1 is arranged on a spindle 2 of a horizontal milling machine and fixed by a fixing assembly 3 (the milling cutter used in the horizontal milling machine is a side milling cutter, etc.), and the spindle 2 is arranged horizontally above the worktable of the horizontal milling machine (not shown in the figure), so that when the spindle 2 rotates, the milling cutter 1 can be driven to process the workpiece on the worktable. The fixing assembly 3 is used to fix the milling cutter 1, and includes a plurality of sleeves 4 and an end sleeve 5. Each sleeve 4 is successively sleeved on the spindle 2 to abut and fix the milling cutter 1. The end sleeve 5 has a circular cross-section and is locked on the end of the spindle 2 to fix each sleeve 4. A clamping portion 6 is provided at the end thereof. The clamping portion 6 includes two opposite receiving surfaces 7 and is in a flat shape. The above-mentioned milling cutter 1 and spindle 2, sleeves 4 and end sleeves 5 of the fixing assembly 3 are generally the same as the known milling cutter and horizontal milling machine, and belong to the known technology. The detailed technical contents such as the structure and operation mode of each component will not be described here. The characteristics of this creation are:

The disassembly tool 10 is used for disassembling or locking the end sleeve 5, and includes a cylindrical body 12, one end of the body 12 is provided with a sleeve portion 14, and the other end is provided with a plug portion 16. The sleeve portion 14 is complementary to the shape of the clamping portion 6, and includes a recess 22 and two clamping surfaces 24 arranged on the inner side of the recess 22. The depth of the recess 22 is greater than that of the clamping portion. 6 is the distance extending axially along the end sleeve 5, so that the sleeve portion 14 can be sleeved on one end of the end sleeve 5 to cover the clamping portion 6. The two clamping surfaces 24 are mutually abutted against the two receiving surfaces of the clamping portion 6. The plug-in portion 16 includes a receiving hole 26, which is square in cross section and connected to the recess 22. The inner side of the receiving hole 26 is provided with two clamping holes 28 opposite to each other.

Thus, the usage, features and functions of the disassembly tool 10 of this invention are as follows:

As shown in FIG. 5, when the milling cutter 1 is to be disassembled, the recess 22 of the disassembly tool 10 is aligned with the clamping portion 6 of the end sleeve 5, and the two clamping surfaces 24 are aligned with the two receiving surfaces of the clamping portion 6. Then, the disassembly tool 10 can be placed on one end of the end sleeve 5, so that the recess 22 and the two clamping surfaces 24 completely fit the outer side of the end sleeve 5 and the clamping portion 6, and then a connecting block 8 of a tool 7 is inserted into the receiving hole 26 (the cross section of the connecting block 8 is also square). shaped), so that the two steel balls (not shown in the figure) provided on the two sides of the connecting block 8 are elastically clamped in each clamping hole 28 (a spring is provided inside the working end 8 to push the steel balls). The tool 7 can be a tool such as a torque wrench or a pneumatic tool with a connecting block 8 at one end, but is not limited to it. The present embodiment is a torque wrench, and the connecting block 8 is a connecting part of a tool such as a torque wrench or a pneumatic tool for inserting a tool head (such as a chuck of a wrench, etc.) or an extension rod. In this way, when the tool 7 is rotated (if the tool 7 is a pneumatic tool, its power output shaft rotates after startup), the disassembly tool 10 can drive the end sleeve 5 to rotate, and then the end sleeve 5 can be removed, and each sleeve 4 can be taken out and the milling cutter 1 can be removed from the central shaft 2.

On the contrary, after the milling cutter 1 is installed on the spindle 2, each sleeve 4 can be placed on the transverse shaft 2 to abut against the milling cutter 1, and then the end sleeve 5 is locked with the disassembly tool 10, and the installation of the milling cutter 1 is completed.

As can be seen from the above, the disassembly tool of the invention can be used to complementally sleeve the end sleeve of the fixed component through the structure of the sleeve part and the plug-in part, and the other end can be used to plug the connection block of the tool, so that the worker can rotate or drive the tool to rotate the disassembly tool, thereby disassembling or locking the end sleeve to complete the disassembly and installation of the milling cutter. Compared with the inconvenience of using a movable wrench to disassemble or lock the end sleeve, the invention is obviously more time-saving and labor-saving in operation, and has great practical value; therefore, the invention does meet the requirements of a new patent, and an application is filed in accordance with the law.

However, the above is only a preferred embodiment of this creation, and it cannot be used to limit the scope of protection of the patent application of this creation. For example, any simple equivalent changes and replacements made according to the scope of the patent application of this creation and the content of the specification should still fall within the scope of protection covered by the patent application of this creation.
