Detailed Description
Referring to fig. 1 to 5, the utility model provides a tool magazine reversing device with magnetic attraction locking function, which comprises a pressure cylinder 10, a connecting member 20, a moving member 30 and a magnetic member 40.
The cylinder 10 is specifically a cylinder or a hydraulic cylinder, and in the present embodiment, a cylinder is used for description. The cylinder 10 has a first end 11 and a second end 12, and the second end 12 extends to form a retractable piston rod 13. Wherein, a fixing seat 50 is disposed on one side of the power cylinder 10, so that the power cylinder 10 is combined and fixed on the tool magazine 1; the second end 12 of the cylinder 10 is provided with two guide holes 14.
The connecting member 20 is a rectangular plate, the connecting member 20 is mounted at the end of the piston rod 13 and is connected to the tool sheath 2 through a tool reversing block 21, wherein the tool sheath 2 has a pivot 2a pivotally mounted on the tool magazine 1, the tool sheath 2 further has a roller 2b clamped on the tool reversing block 21, when the piston rod 13 of the hydraulic cylinder 10 is in the retracted position, the tool sheath 2 is generally horizontal as shown in fig. 5, the tool sheath 2 is at the higher position, and as shown in fig. 4, when the piston rod 13 of the hydraulic cylinder 10 is in the extended position, the tool sheath 2 is vertical and at the lower position.
The moving component 30 is slidably disposed on the periphery of the cylinder 10 parallel to the moving direction of the piston rod 13, and the moving component 30 has a connecting end 31 and a magnetic end 32, the connecting end 31 and the piston rod 13 are jointly connected to the connecting member 20, and when the piston rod 13 is actuated, the moving component 30 generates a sliding motion relative to the cylinder 10. In the present embodiment, the moving component 30 is two guide rods 33 and is disposed through the guide hole 14, and the connecting end 31 and the magnetic end 32 are disposed at two ends of the guide rods 33, respectively.
The magnetic member 40, specifically a strong magnet, is disposed at the first end 11, and the magnetic member 40 can magnetically attract the magnetic end 32 to lock the piston rod 13, so as to prevent the knife pouch 2 from falling down. In this embodiment, the magnetic attraction of the magnetic member 40 is greater than the sum of the weights of the knife sheath 2 and the knife, and when the piston rod 13 is in the retracted position relative to the hydraulic cylinder 10, the magnetic end 32 of the moving assembly 30 is attracted by the magnetic member 40, so as to avoid the problem that the knife sheath 2 droops due to the fact that the piston rod 13 slides out of the hydraulic cylinder 10 due to the gravity of the knife sheath 2 or the knife sheath 2 with the knife when the hydraulic cylinder 10 is under no pressure (if the air pressure is insufficient).
In the embodiment, the second magnetic plate 41 is installed at the first end 11, and the magnetic end 32 is a first magnetic plate, and the second magnetic plate 41 bears the strong magnet, so that the magnetic member 40 and the first magnetic plate attract each other. In other embodiments, the magnetic member 40 and the first magnetic plate can be a combination of two magnetically attracted magnets or a combination of a magnet and a magnetically conductive metal, which can achieve the same magnetic attraction effect.
In other embodiments, the first magnetic plate is U-shaped, the concave portion of the first magnetic plate corresponds to the periphery of the cylinder 10, one end of the guide rod 33 is locked to the connecting member 20, and the other end is locked to the first magnetic plate; the second magnetic plate 41 is U-shaped, which is substantially similar to the first magnetic plate, and the strong magnets are four and each of disk shape, and further include two large strong magnets 42 and two small strong magnets 43, which are respectively disposed on both sides of the second magnetic plate 41 in a group of one large magnet and one small magnet.
As shown in fig. 5, when the piston rod 13 is in the retracted position relative to the hydraulic cylinder 10, the large strong magnet 42 and the small strong magnet 43 of the magnetic member 40 attract the magnetic end 32 (i.e. the first magnetic plate) of the moving assembly 30, so as to form a locking effect, and under the condition that the air pressure of the hydraulic cylinder 10 is insufficient or is not pressurized, the piston rod 13 slides out of the hydraulic cylinder 10 due to the weight of the single knife sheath 2 or the sum of the weights of the single knife sheath 2 and the single tool, so that the knife sheath 2 sags, which affects the tool changing operation of the tool changing arm, and related risks are avoided.
The utility model discloses simple structure, the cost is compared and is low in knowing auto-lock cylinder, sees through simultaneously that the looks of removing subassembly 30 and magnetic part 40 is inhaled and form the locking outside, removes the guide that subassembly 30 can regard as the flexible action of piston rod 13, makes the back knife action more reliable and stable.
