Description

Tool magazine with brake mechanism

This creation is about a tool magazine structure, especially a tool magazine with a brake mechanism.

According to the conventional processing machine, in addition to a machining spindle, a tool change mechanism and a tool magazine are arranged, and the tool magazine has a cutter plate for mounting a plurality of machining type tools, whereby the machining machine is Depending on the machining operation, the tool on the cutter head is selected for use by the machining spindle, and the tool change operation is performed by the tool change mechanism.

However, in order to perform a tool change operation, the machine must first drive the tool magazine to rotate to select the tool to be replaced. When selected, the tool magazine stops rotating, so that the tool change mechanism can start the tool change operation, but When the tool magazine stops rotating, the situation that the cutter head continues to sway frequently occurs, which affects the accuracy of the tool change operation. Therefore, the existing tool magazine structure still needs to be improved, so that the relevant industry can solve it.

In order to solve the above problems, the present invention provides a tool magazine with a brake mechanism, and the brake mechanism can selectively engage the cutter head to stabilize the position of the cutter disc.

In order to achieve the above object, the tool magazine of the brake mechanism comprises: a base disposed on a machine tool; a power output shaft rotatably disposed on the base; and a cutter disk coupled to the output shaft, And a plurality of tools are installed on the periphery; and a brake mechanism is disposed on the base, and is electromagnetically switched between a release position and a bite position for respectively releasing and biting the cutter head, wherein the brake When the mechanism is energized, it is in the release position, and when the brake mechanism is in the power-off state, it is in the occlusion position.

The brake mechanism comprises an armature plate and a brake pad, and the brake pad is connected to the cutter disc. When the release position, the armature plate and the brake pad have a spacing. When the bit is engaged, the armature plate engages the brake pad. .

The brake mechanism further includes an elastic component. When the release position, the armature plate presses against the elastic component. When the position is engaged, the armature plate can be pushed by the elastic restoring force of the elastic component to engage the brake pad.

The brake mechanism further comprises an electric control unit and a coil electrically connected to the electronic control unit. When the release position, the electronic control unit is energized, so that the coil can generate a magnetic attraction to the armature plate, and the electronic control is performed when the position is engaged. The unit is in a de-energized state, causing the magnetic force of the coil to disappear.

The brake mechanism further includes a pedestal recessed with a receiving groove and a ring groove disposed beside the accommodating groove for respectively placing the elastic component and the coil, and the length of the elastic component in the normal state is greater than the capacity. The depth of the groove.

Thereby, when the output shaft stops rotating and the cutter disc stops rotating, the electronic control unit is in a power-off state, so that the magnetic force of the coil disappears, and at this time, the armature plate is not attracted by the magnetic force; The elastic restoring force pushes up to engage the brake pads to stabilize the position of the cutter disc, so as to avoid the continuous shaking of the cutter disc, thereby increasing the accuracy of the tool changer during the tool change operation.

For the convenience of the description, the central idea expressed in the column of the above novel content is expressed by a specific embodiment. The various items in the embodiments are set forth in proportion to the description and not in the

Referring to FIG. 1 to FIG. 4, the present invention provides a tool magazine 100 with a brake mechanism, which can be used in a machine tool (not shown), and preferably, the tool magazine 100 of the present invention is a swash plate. A tool magazine 100 comprising:

A base 10 is fixed on a machine tool (not shown) and has an accommodating space 11 at the center of the accommodating space 11 and has a barrel-shaped fixing portion 12 and a accommodating space. 11 The opposite side of the machine tool is open.

A drive motor 20 is disposed in the accommodating space 11 and has a power output shaft 30.

A cutter head 40 is coupled to the output shaft 30, and the accommodation space 11 is closed. The cutter head 40 is mounted with a plurality of clamp holders 41 on the periphery thereof, and each clamp holder 41 is provided with a cutter 42.

A brake mechanism 50 is disposed on the fixed portion 12 of the base 10 and includes an electronic control unit 51, a shaft 52, a base 53, a coil 54 electrically connected to the electronic control unit 51, and a spring element 55, an armature plate 56 and a brake pad 57, wherein the electronic control unit 51 and the shaft 52 are fixed in the fixed portion 12, and the base 53 and the armature plate 56 are sleeved on the shaft 52, the brake The sheet 57 is connected and fixed to the cutter head 40, and the armature plate 56 is located between the base 53 and the brake pad 57.

In addition, the pedestal 53 is provided with a receiving groove 58 and a ring groove 59 disposed adjacent to the receiving groove 58 toward one side of the armature plate 56, as shown in FIG. 2, for respectively providing the elastic member 55 and the coil 54. When the elastic element 55 is in the normal state, the length is greater than the depth of the accommodating groove 58, and when the electronic control unit 51 is in the energized state, the coil 54 can generate the magnetic force. Otherwise, when the electronic control unit 51 is in the power-off state, the coil is The magnetic force of 54 disappears, and the side of the armature plate 56 facing the base 53 can be attracted by the magnetic force generated by the coil 54 and can be pushed up by the elastic member 55.

The above is an overview of the structure and shape of the creation, and the use of the creation and the principle of its efficacy can be stated as follows:

When the tool change mechanism (not shown) of the machine tool is to be replaced, the drive motor 20 drives the output shaft 30 to rotate to drive the cutter head 40 to rotate. At this time, the electronic control unit 51 is In the energized state, the coil 54 generates a magnetic force to attract the armature plate 56, and the magnetic force of the coil 54 to attract the armature plate 56 is greater than the elastic restoring force of the elastic member 55. Therefore, the armature plate 56 is attracted by the magnetic force generated by the coil 54. After that, the elastic member 55 can be pressed, as shown in FIG. 2, and at this time, there is a distance D between the armature plate 56 and the brake pad 57, so that the integral brake mechanism 50 is located at the release position, so that the cutter head 40 can be Free swing.

When the tool machine selects the tool 42 to be replaced, the drive motor 20 stops acting to stop the rotation of the cutter head 40. At this time, the electronic control unit 51 is in a power-off state, so that the magnetic force of the coil 54 disappears. At this time, the armature plate 56 is not attracted by the magnetic force. On the contrary, it can be pushed by the elastic restoring force of the elastic member 55 to engage the brake pad 57. As shown in FIG. 4, the integral brake mechanism 50 is located at the occlusion position. The cutter head 40 can be stably fixed.

Therefore, the brake mechanism 50 of the present invention uses an electromagnetic method to switch between the release position and the bite position for respectively releasing and engaging the cutter head 40. After the cutter head 40 stops rotating, the armature plate 56 is used. By snapping the brake pad 57, the situation that the cutter head 40 is continuously swayed can be avoided, thereby increasing the accuracy of the tool changer during the tool change operation.

The above embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Any modification or change that is not in violation of the spirit of this creation is the scope of patent application for this creation.
