The present invention relates to a reverse knife device, and more particularly to a knife storage device with a magnetic lock.

Pressing, the tool magazine's tool magazine is in the process of changing the tool. It is most afraid that the power cylinder suddenly pushes out the telescopic rod due to insufficient pressure, and the knife sleeve automatically slides down, which in turn affects the tool change operation. Therefore, in order to avoid such a problem, for example, Taiwan Patent No. M349815 discloses a tool magazine linkage rapid tool change mechanism, wherein the cylinder is provided with a self-locking device, and the self-locking device can lock the cylinder piston rod in the cylinder during the spindle machining. And when the machining needs to change the knife, it is opened to increase the safety of the tool machining.

However, the self-locking device uses a pressure cylinder, such as a cylinder, so that the installation cost is high, and the equipment cost burden is invisibly increased.

In order to solve the above problems, the present invention discloses a tool magazine reversing device with magnetic locking, which forms a lock by mutual magnetic attraction between the moving component and the magnetic member when the piston rod is in the retracted position, so as to avoid pressure loss of the cylinder. At the same time, the knife sleeve is drooped due to the weight, so as to avoid affecting the tool change operation.

In order to achieve the above object, in the present embodiment, a knife-locking device with a magnetic lock is provided, which comprises a pressure cylinder, a connecting member, a moving component and a magnetic member. The pressure cylinder has a first end and a second end, and the second end defines a telescopic piston rod; the connecting member is coupled to the end of the piston rod for connecting the knife sleeve; and the moving component is parallel to the moving direction of the piston rod The sliding component is disposed on the periphery of the pressure cylinder, and the moving component has a connecting end and a magnetic end, the connecting end is coupled to the connecting member; the magnetic component is disposed at the first end of the pressure cylinder, and the magnetic component is magnetically attracted to the magnetic end To lock the piston rod to avoid sagging the sleeve.

In another embodiment of the present invention, the magnetic end is a first magnetic plate, and the magnetic member is a strong magnet disposed at the first end.

In another embodiment of the present invention, a fixing base is further included, one side of which is connected to the pressure cylinder and the other side of which is coupled to the tool magazine.

Thereby, when the piston rod of the present invention is in the retracted position, the magnetic member can attract the magnetic end of the moving component to form a locking function, and the piston rod can be prevented from slipping out if the pressure of the cylinder is insufficient or the pressure is lost. The pressure cylinder causes the knife sleeve to sag, affecting the tool change operation of the tool change arm.

Moreover, the creation structure is simple, the cost is low, the installation is fast, and the industry is competitive.

The exemplified embodiments of the present invention are described in detail below with reference to the accompanying drawings, and are not intended to limit the technical principles of the present invention to the specific disclosed embodiments, and the scope of the present invention is limited only by the scope of the patent application, including alternatives, modifications, and Equivalent.

Referring to FIG. 1 to FIG. 5, the present invention is a knife-locking device with a magnetic lock, which comprises a pressure cylinder 10, a connecting member 20, a moving assembly 30 and a magnetic member 40. The tool magazine with the magnetic lock is provided in the tool magazine 1 to match the tool change operation.

The cylinder 10 is a cylinder or a hydraulic cylinder, and is illustrated by a cylinder in the present embodiment. The pressure cylinder 10 has a first end 11 and a second end 12, and the second end 12 defines a telescopic piston rod 13. There is a fixing seat 50 on one side of the pressure cylinder 10, so that the pressure cylinder 10 is fixedly coupled to the tool magazine 1; the pressure cylinder 10 is provided with two guiding holes 14 at the second end 12.

The connecting member 20 is formed in a rectangular plate shape, and the connecting member 20 is coupled to the end of the piston rod 13 and connected to the knife sleeve 2 through a falling block 21, wherein the knife sleeve 2 has a pivot 2a and is pivoted In the tool magazine 1, the knife sleeve 2 further has a roller 2b and is clamped to the inverted knife block 21. When the piston rod 13 of the pressure cylinder 10 is in the retracted position, the knife sleeve 2 is horizontal as shown in FIG. At this time, the knife sleeve 2 is at a higher position, and as shown in Fig. 4, when the piston rod 13 of the cylinder 10 is in the extended position, the knife sleeve 2 is vertically and at a lower position.

The moving assembly 30 is disposed on the periphery of the cylinder 10 in a sliding direction parallel to the moving direction of the piston rod 13, and the moving assembly 30 has a connecting end 31 and a magnetic end 32. The connecting end 31 and the piston rod 13 are coupled to each other. When the piston rod 13 is actuated, the moving assembly 30 is slidably moved relative to the cylinder 10. In the present embodiment, the moving component 30 is a two guiding rods 33 extending through the guiding holes 14 , and the connecting end 31 and the magnetic end 32 are respectively disposed at two ends of the guiding rod 33 .

The magnetic member 40 is a strong magnet and is disposed at the first end 11. The magnetic member 40 is magnetically attracted to the magnetic end 32 for locking the piston rod 13 to prevent the knife sleeve 2 from falling. In the present embodiment, the magnetic force of the magnetic member 40 is greater than the weight of the knife sleeve 2 and the cutter, and is used to attract the magnetic force of the moving assembly 30 by the magnetic member 40 when the piston rod 13 is in the retracted position relative to the cylinder 10. The end 32, thereby avoiding the pressure loss of the pressure cylinder 10 (such as insufficient air pressure), without causing the piston rod 13 to slide out of the pressure cylinder 10 due to the gravity of the knife sleeve 2 or the cutter sleeve 2 provided with the cutter, thereby causing the knife sleeve 2 The problem of sagging occurs.

The present invention further includes a second magnetic plate 41 coupled to the first end 11, and the magnetic end 32 is a first magnetic plate, and the second magnetic plate 41 carries the strong magnet to make the magnetic member 40 and the first magnetic The plates are sucked.

In the present embodiment, the first magnetic plate is U-shaped, and the concave portion thereof corresponds to the circumference of the pressure cylinder 10, and the guiding rod 33 is locked at one end to the connecting member 20 and the other end is locked to the first magnetic plate; The second magnetic plate 41 has a U shape, which is substantially similar to the first magnetic plate. The strong magnets are four and each has a disk shape. The strong magnet further includes two large powerful magnets 42 and two small powerful magnets 43. They are respectively disposed on both sides of the second magnetic plate 41 in a group of one large and one small.

As shown in FIG. 5, when the piston rod 13 is in the retracted position relative to the cylinder 10, the large-strength magnet 42 and the small-powerful magnet 43 of the magnetic member 40 attract the magnetic end 32 of the moving assembly 30 (ie, the first magnetic plate). ), the locking action is thus formed, and in the case where the air pressure of the cylinder 10 is insufficient or the pressure is lost, the piston rod 13 is slid out due to the weight of a single pocket 2 or the weight and influence of a single pocket 2 and a single cutter. The pressure cylinder 10 causes the knife sleeve 2 to sag, affecting the tool change operation of the tool change arm, and eliminating the associated risks.

Moreover, the creation structure is simple, the cost is lower than that of the conventional self-locking cylinder, and the locking component is formed by the suction of the moving component 30 and the magnetic component 40, and the moving component 30 can also serve as a guide for the expansion and contraction of the piston rod 13. Lead, so that the reverse knife action is more stable and reliable.
