Abstract

A tool magazine door guard device includes at least one guide rail, a telescopic door panel unit and at least one driving unit. The guide rail is disposed on a side of the magazine door and extends along a first axial direction and has a first end and a second end. The telescopic door panel unit has a positioning member, a linking member, a plurality of scales, and a shielding member connected to the scales. When the driving unit drives the linking member to approach the positioning member, the scales are in a condensation state. When the linking member is away from the positioning member, the scales are in an unfolded state. Thereby, the guard device can provide a better shielding effect for the magazine door, and can effectively prevent debris and cutting fluid from splashing to the tool magazine.

Description

Referring to FIG. 1 , FIG. 2 and FIG. 4 , an embodiment of the tool door door guard device of the present invention is disposed on the side of the tool magazine door 1 , and the tool magazine door 1 is defined by a door frame 101 , and the door frame 101 can be defined. The inner side 102 corresponding to a magazine (not shown) and the outer side 103 of a corresponding processing spindle (not shown) are formed. The protection device comprises a guide rail 10, a telescopic door panel unit 20 and a driving unit 30.

The guide rail 10 has a long rod shape and is fixed to the inner side 102 of the door frame 101 and extends along a first axial direction X, and has a first end 11 and a first end 11 opposite to the first end 11 The second end 12.

The retractable door panel unit 20 can cause the magazine door 1 to be sealed or opened, and has a pair of positioning members 21 corresponding to the second end 12 and positioned relative to the magazine door 1, along a first axial direction X. Conversely, the linking member 22 of the positioning member 21, a plurality of scales 23 which are disposed along the first axial direction X, a shielding member 24 connected to the scales 23 and corresponding to the inner side 102, and a plurality of the shielding members 24 The locking set 25 is secured to the scales 23. In conjunction with FIG. 3, each of the scales 23 has a connecting end portion 231 and a overlapping end portion 232 opposite the connecting end portion 231 along the first axial direction X. The shielding member 24 is disposed on the inner side of the scales 23 and has a plurality of fixing portions 241 respectively fixed to the connecting end portions 231 and a plurality of fixing portions are integrally connected to the fixing portions. In the shielding portion 242 on the 241 side, the shielding member 24 of the present embodiment is an integral cloth material, that is, the fixing portions 241 are integrally connected to the shielding portions 242. Each of the locking groups 25 has a clamping plate 251 for pressing the corresponding fixing portion 241 to the connecting end portions 231, and a plurality of rivets 252 for fastening the clamping plate 251 to the connecting end portions 231. A scale 23 at one side end is connected to the positioning member 21, and a scale 23 located at the other side end along the first axial direction is connected to the linking member 22. The linking member 22 has a slidably sleeved on the guide rail 10. Loop 221.

The driving unit 30 is spaced apart from the guide rail 10 along a second axial direction Y perpendicular to the first axial direction X, and can drive the linking member 22 to approach or away from the positioning member 21. The driving unit 30 of the embodiment is exemplified by a rodless cylinder, and has a cylinder 31 and a driving member 32 slidably disposed outside the cylinder 31 along the first axial direction X (rodless cylinder) The structure and the principle of operation are not within the scope of the present invention, and the internal structure diagram is not shown and will not be described again. The driving member 32 is connected to the linking member 22.

The actual use and operation of the guard device composed of the above-mentioned members will be described as follows: as shown in FIG. 1 to FIG. 4, the state in which the guard device is shielded from the magazine door 1 is explained. At this time, the link member 22 is in a state of being shielded. With respect to the positioning member 21, the connecting end portions 231 of the scales 23 are apart from each other and the scales 23 are in an unfolded state. The action of the overlapping end portions 232 of the scales 23 on the adjacent one of the scales 23 causes the erecting portions of the adjacent two scales 23 to be kept in close contact to prevent leakage. Plus the shield The arrangement of 24 can further achieve the effect of blocking fines and moisture from infiltrating into the inner side 102 from the outer side 103.

When the tool change operation is to be performed and the magazine door 1 is to be opened, the drive unit 30 can be activated, and the drive member 32 is caused to slide along the first axial direction X and on the cylinder block 31, the drive When the member 32 moves to bring the linking member 22 closer relative to the positioning member 21, the connecting end portions 231 of the scales 23 approach each other and the scales 23 are in a condensed state (see FIGS. 5 and 6). ). The loop 221 of the linking member 22 is sleeved on the guide rail 10 for smooth sliding.

Therefore, by using the scales 23 of the retractable door panel unit 20 and the arrangement of the shielding member 24, the scales 23 can be provided with a better shielding effect on the magazine door 1 when deployed, and can effectively prevent debris, The cutting fluid is sprayed onto the inner side 102 of the magazine door 1 to avoid damage to the machine parts and to reduce the trouble of cleaning.

It is worth mentioning that the driving unit 30 of the embodiment is an example of a rodless cylinder, but the rodless cylinder is not the only option, and the linkage 22 can be driven to approach or away from the positioning member 21. The institutions are applicable. In fact, the driving unit can also adopt a rod pressing cylinder having a cylinder body and a piston rod which is retractable with respect to the cylinder body and along the first axial direction, and the rod rod end is connected to The linkage (not shown). In addition, the driving unit may also include a rack extending along the first axial direction, a motor necessarily located at the linking member, and a gear (not shown) driven by the motor and engaged with the rack. Alternatively, the drive unit may also include a generation relative to the magazine door a positioning motor, a pair of pulleys respectively disposed on the first and second ends of the shaft, a belt wound around the pulleys and connected by the linking member, wherein a pulley is driven by the motor (not shown).

In summary, the tool door guard device of the present invention has a simple overall structure, is easy to manufacture, and can produce a better shielding effect, and can truly achieve the object of the present invention.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
