Description

Technical Field

[0001] The utility model relates to the technical field of milling and drilling tools, in particular to a drilling tool for machine tool milling. Background Art

[0002] A drilling tool is a tool used to drill through holes or blind holes in solid materials and can enlarge existing holes. This type of drilling tool is suitable for processing materials on various machine tools.

[0003] Drilling tools are usually used in conjunction with machine tools. They are tools used to drill holes in materials during machine tool milling processing. The specifications and sizes of the tools are fixed on the market. Under normal circumstances, the drill tool will rotate around the axis to perform drilling operations on the surface of the processed material. The drill tool is usually made of high-speed steel.

[0004] Existing drilling tools are usually installed with nuts and bolts. This installation method requires regular maintenance of the equipment. At the same time, if the machine tool space where the tool is installed is small, this installation method is more troublesome. When the nuts and bolts are installed and fixed in use, the drilling tool needs to be rotated to drill the workpiece, causing the installation part of the tool to loosen under long-term rotation, causing the tool to fall directly off the machine tool during the processing process, posing certain risks to nearby workers.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figures 1 to 5 , which is the first embodiment of the utility model, provides a technical solution: a drilling tool for machine tool milling, comprising a machine tool 1 and a lifting platform 2 arranged on the machine tool 1, the lifting platform 2 is used to lift the installed drilling tool 6 to process the workpiece, a starting motor 4 is arranged on the lifting platform 2, and a rotating shaft 41 is arranged on one side of the starting motor 4, a mounting cylinder 3 is arranged on the lifting platform 2, and a locking assembly 5 is arranged inside the mounting cylinder 3, the locking assembly 5 is used to lock the installed drilling tool 6, the drilling tool 6 is arranged in the locking assembly 5, and the drilling tool 6 and the locking assembly 5 are tightly fitted;

[0027] The locking assembly 5 includes a rotating wheel 51 arranged at one end of the rotating shaft 41 away from the starting motor 4, the rotating wheel 51 is used to rotate synchronously under the drive of the rotating shaft 41, a square extension rod 52 arranged on the other side of the rotating wheel 51, the square extension rod 52 is used to prevent the power on the rotating wheel 51 from being unable to be transmitted to the drilling tool 6, an elastic clamping plate 53 arranged on the other side of the square extension rod 52, one side of the elastic clamping plate 53 is a guide plate opened outward, when the elastic clamping plate 53 is received into the mounting tube 3, the mounting tube 3 can be used to clamp the drilling tool 6, an array of spherical rods 54 arranged on the elastic clamping plate 53, the spherical rods 54 are used to cooperate with the circulation groove 32 inside the mounting tube 3, and a first spring 55 arranged on the outside of the square extension rod 52, the first spring 55 is used to push the elastic clamping plate 53 out of the mounting tube 3 in the absence of external force.

[0028] A slide groove 31 is formed through the installation tube 3 , and the slide groove 31 is used to limit the lifting and lowering of the fixing rod 72 . A circulation groove 32 is formed inside the installation tube 3 , and the circulation groove 32 and the spherical rod 54 are engaged and slidable.

[0029] A rotating block 511 is provided on the rotating wheel 51, and the rotating block 511 is used to engage with the ratchet 71 so that the rotating wheel 51 can only rotate counterclockwise. A second spring 512 is provided on the rotating block 511 close to the rotating wheel 51, and the second spring 512 is fixedly connected to the rotating wheel 51. The second spring 512 is used to provide elastic force so that the rotating block 511 can always slide with the ratchet 71.

[0030] The cam 53 is then rotated counterclockwise to allow the spring 54 to move in a reverse direction and the spring 56 to move in a reverse direction, thereby locking the drill 6.

[0031] Example 2

[0032] See also Figures 1 to 5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0033] A bearing 42 is provided on the rotating shaft 41, and the bearing 42 is fixedly connected to the mounting tube 3. A transmission assembly 7 is provided on the mounting tube 3, and the transmission assembly 7 is used to engage with the rotating wheel 51 on the locking assembly 5 so that it will not affect the locked drilling tool 6 during the rotation process.

[0034] The transmission assembly 7 includes a ratchet 71 movably arranged inside the mounting tube 3, the ratchet 71 is used to engage with the rotating block 511 on the rotating wheel 51 to prevent the drilling tool 6 from falling off from the elastic clamp 53 during rotation, a fixed rod 72 symmetrically arranged on the ratchet 71, an L-shaped plate 73 arranged on the fixed rod 72, the L-shaped plate 73 is used to facilitate the lifting and lowering of the ratchet 71, and a sliding plate 74 arranged at the other end of the L-shaped plate 73.

[0035] A limiting rod 75 is provided through the L-shaped plate 73, and the limiting rod 75 is used to limit the lifting and lowering of the L-shaped plate 73. Support plates 76 are provided at both ends of the limiting rod 75, and the support plates 76 are fixedly connected to the mounting tube 3. A third spring 77 is sleeved on the outside of the limiting rod 75, and the third spring 77 is used to reset the ratchet 71 in the absence of external force, so that the rotating block 511 is engaged therein to form a one-way limiting state.

[0036] During use, when the drilling tool 6 has been installed in the installation tube 3, when the motor 4 is started to drive the rotating shaft 41 to rotate, the rotating block 511 on the rotating wheel 51 and the ratchet 71 will be disengaged in the clockwise rotation state, so that the clockwise rotating shaft 41 drives the elastic clamping plate 53 below to rotate, and the disengaged rotating wheel 51 and the installation tube 3 will not rotate synchronously. In this state, the elastic clamping plate 53 rotating clockwise can be further locked in the installation tube 3. When the locking state of the two is more secure, the friction between the spherical rod 54 and the circulation groove 32 can be used to lock the two. When the rotating shaft 41 rotates counterclockwise, the mounting tube 3 is driven to rotate synchronously, thereby driving the mounting tube 3 to rotate synchronously. In this state, the locking of the drilling tool 6 by the entire elastic clamp 53 is more stable. When the rotating shaft 41 rotates counterclockwise, the mounting tube 3 is driven to rotate synchronously, and the elastic clamp 53 will not extend out of the mounting tube 3, but the entire locking state will be maintained in the initial state. When the entire device stops working and the drilling tool 6 is replaced, the sliding plate 74 is pulled down to release the engagement between the rotating wheel 51 and the ratchet 71, and the mounting tube 3 is rotated clockwise, so that the elastic clamp 53 is extended to release the locking of the drilling tool 6, thereby facilitating the replacement of the drilling tool 6.

[0037] The remaining structures are the same as those of Example 1.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
