Description

Pressure relief structure of knife magazine

The invention relates to a technical field related to a tool tool magazine, in particular to a pressure relief structure of a knife magazine with a silent knife.

The conventional knife magazine has a silent button mechanism, such as the Chinese Patent Publication No. I397453, 587973, etc., as shown in Figures 8 and 9, the structure generally includes a shaft 91 and a fixed end of the shaft 91 facing downward. A plate 92 and a tool change arm 93 coupled to the rotating shaft 91 and driven by the swivel are provided. Wherein, the plate 92 has a plurality of positioning holes 922 at a predetermined position toward the lower end surface. The two ends of the tool changing arm 93 respectively have oppositely facing knives 932, an actuating seat 934 that interacts with the abutting plate 92, and a knives 936 that are pivotally coupled with the actuating seat 934 and protruded from the knives 932. And the plurality of returning actuators 934 and the first and second elastic members 937 and 938 of the knives 936.

As can be seen from the description of the foregoing description, in the normal state, the movable seat 934 is pressed against the pressing plate 92, and the first elastic member 937 is compressed and the fastener shank 936 is retracted to press the second elastic member 938, only the change arm 93 When the actuator 934 is swung to the position of the corresponding positioning hole 922, the first and second elastic members 937 and 938 can be released, and this compression condition is normal, whether the tool change arm 93 is on standby on the machine tool. Or when it is placed in the warehouse as a material, the first and second elastic members 937 and 938 under such long-term compression are extremely susceptible to elastic fatigue due to prolonged compression, and the buckle holder 936 cannot be obtained once the elasticity is fatigued. A normal instant kick or retraction knife is achieved.

In view of the above problems and deficiencies of the prior art, the main object of the present invention is to provide a pressure relief structure for a knife magazine with a silent knife to overcome the above-mentioned shortcomings of the prior art.

According to the above object of the present invention, a pressure relief structure of a knife magazine without a sound knives is provided. The tool holder has a rotating shaft, a plate fixed to the lower end surface of the rotating shaft, and a driving shaft connected to and driven by the rotating shaft. a tool changing arm of the swinging pen, the two ends of the tool changing arm respectively have a buckle edge, a movable seat interacting with the abutting plate, a buckle bar coupled with the movable seat pivotally, and a plurality of returning movable seats and a buckle bar The first and second elastic members are characterized in that: the pressure relief structure comprises a plurality of pressure relief grooves, each of the pressure relief grooves is arranged in a ring shape with a concentric rotation axis, and the symmetric depression is formed on the lower end surface of the plate, and is located at Standby position of the tool change arm.

In the following, the embodiment of the pressure relief structure of the knife blank of the present invention will be further described with reference to the related drawings. To facilitate the understanding of the embodiments of the present invention, the same components are denoted by the same reference numerals.

Referring to Figures 1 to 7, the pressure relief structure of the knife magazine of the present invention has a sound-locking mechanism (conventional) including a rotating shaft 91 and a fixed end face of the rotating shaft 91. The plate 1, and a tool change arm 93 connected to the rotating shaft 91 and driven by the swivel. Wherein, the two ends of the tool changing arm 93 respectively have oppositely facing knives 932, an actuating seat 934 that interacts with the yoke 1 and a knives 936 that are pivotally coupled to the shank 932. And the plurality of returning actuators 934 and the first and second elastic members 937, 938 of the shank 936, wherein: The pressure relief structure includes a plurality of pressure relief grooves 12, and each of the pressure relief grooves 12 is arranged in a ring shape with a concentric rotation shaft 91, and is formed symmetrically on the lower end surface of the abutting plate 1 and is located at the standby end of the tool change arm 93. position. The relief grooves 12 extend at opposite sides and have at least one class of slopes.

Therefore, the above is a description of the components and assembly methods of the ball-type slip coiling ring according to a preferred embodiment of the present invention. The operating characteristics of the embodiment of the present invention are described below.

In the normal state, the tool changing arm 93 is in the standby position, that is, the actuating seat 934 of the tool changing arm 93 is abutted against the pressure releasing groove 12, so that the actuating seat 934 is interlocked with the buckle bar 936 to protrude from the blade opening 932 of the tool changing arm 93. The first and second elastic members 937, 938 are placed in a released state.

<tool change operation - in place>

When the tool change is performed, the rotary shaft 91 drives the change arm 93 toward the tool magazine (with the work The machine tool spindle (not shown) moves the tool change position; during the process, when the tool change arm 93 rotates, the action block 934 rotates, and the self-release pressure groove 12 is disengaged, and the end face of the resist plate 1 is pressed against Pushing the seat 934 downwardly, compressing the first elastic member 937 and interlocking the buckle lever 936 to retract to compress the second elastic member 938, thereby preventing the knife edge 932 of the tool change arm 93 from contacting the cutter 2, and the buckle lever 93 is The tool 2 forms a collision.

<tool change operation - drawing knife>

When the knife edge 932 of the tool change arm 93 is fastened to the tool 2 (conventional technique), the rotary shaft 91 moves the tool change arm 93 downward, and the cutter 2 is separated from the tool magazine by the cutter shaft.

<tool change operation - tool change>

The rotating shaft 91 rotates the tool changing arm 93 by 180 degrees, so that the tool 2 that is pulled out from the tool magazine and the main shaft is mutually exchanged, and the tool changing arm 93 is moved upward, so that the tool 2 on the tool changing arm 93 is respectively sleeved on the knife. The library and the spindle achieve the action of changing the knife.

<Back to pressure release position>

When the tool changing operation is completed, the rotating shaft 91 reversely rotates the tool changing arm 93, so that the actuating seat 934 of the tool changing arm 93 is displaced to the pressure releasing groove 12 of the plate 1, so that the first and second elastic members 937 938 returned to the release state again.

The above description is only for the preferred embodiment of the present invention, and is intended to clarify the features of the present invention, and is not intended to limit the scope of the embodiments of the present invention. Changes that are well known to those skilled in the art are still within the scope of the invention.
