Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of magnetic workbenches, in particular to a magnetic workbench. Background Art
[0002] The working principle of a magnetic workbench is to pass a DC excitation current through an excitation coil, forming a closed magnetic circuit, which firmly attracts the workpiece to the workbench surface. When the excitation current of a traditional magnetic workbench is cut off, the workpiece remains attracted to the workbench due to residual magnetism, making it difficult to remove. In this case, a pulsating current must be passed through the excitation coil to demagnetize the workpiece. However, the electrical structure of a traditional magnetic workbench is easily damaged during the current switching process, so a new magnetic workbench was proposed. Utility Model Content

[0029] See also Figure 1 , a magnetic workbench includes a frame structure and an adjustment structure.
[0030] See also Figure 2 The frame structure includes a track 1, two rollers 2 distributed on the left and right are engaged above the track 1, and the same workbench 3 is connected to the two rollers 2 for common rotation. Two fixed blocks 4 and a first interface 6 and a second interface 7 are fixedly installed in front of the track 1. Two sliding rods 5 distributed up and down are fixedly installed between the two fixed blocks 4. The first interface 6 and the second interface 7 are located between the two fixed blocks 4 and behind the sliding rod 5.
[0031] See also Figure 3-6 The adjustment structure includes a slide plate 8, which is sleeved with two slide bars 5. Two support blocks 9 are fixedly mounted on the slide plate 8. Each support block 9 is rotatably connected to a bent rod 10. An input port 11 is installed at one end of the bent rod 10 away from the support block 9. A disc 12 is sleeved together at the opposite ends of the two bent rods 10. Two protrusions 13 are clamped inside the slide plate 8. A spring 14 is provided between each protrusion 13 and the slide plate 8. The front end of the protrusion 13 on the same side contacts the rear end of the bent rod 10. The disc 12 and the slide plate 8 are sleeved together with a steering wheel 15.
[0032] It should be noted that the steering wheel 15 is not only an adjustment device for left and right movement, but also a switch for demagnetization and magnetization.
[0033] In this embodiment, a hexagonal groove 1 is provided at the front end of the left roller 2, so that the roller 2 always maintains rolling friction with the track 1 during the left and right movement without slipping.
[0034] It should be noted that the workbench 3 can be moved left and right only when the steering wheel 15 is engaged with the groove of the roller 2, while the stability of the left and right movement of the device is ensured without slipping.
[0035] In this embodiment, the first interface 6 and the second interface 7 are respectively an excitation current terminal and a pulsating current terminal, and the input port 11 is a current input terminal.
[0036] It should be noted that when an excitation current is passed through the magnetic workbench 3, the workbench 3 will generate magnetic force. Cutting off the power cannot completely eliminate the magnetic force of the workbench 3. Only when a pulsating current is passed through it will the magnetic force completely disappear, and the workpiece can be easily removed.
[0037] In this embodiment, the skateboard 8 is provided with two left and right through holes 1 distributed up and down, two convex grooves 2 symmetrically about the center of the skateboard 8, and a through hole 2 in the middle. The protrusion 13 is clamped in the groove 1 and can move back and forth along the groove 2. The spring 14 is always in a compressed state, and the slide rod 5 is plugged into the skateboard 8 through the through hole 1.
[0038] It should be noted that the slide plate 8, as the core fixed part of the adjustment structure, ensures the stability of left and right movement through the slide rod 5. At the same time, the internally clamped protrusion 13 and the cooperation of the bent rod 10 and the support block 9 ensure the stable contact between the input port 11 and the first interface 6 or the second interface 7. At the same time, the steering wheel 15 and the roller 2 can be separated to prevent the problem of the workbench 3 moving due to the accidental turning of the steering wheel 15.
[0039] In this embodiment, the disc 12 is provided with two through holes 3 that are symmetrical about the axis of the disc 12 and a through hole 4 in the middle, and the adjustment assembly is a bilaterally symmetrical mirror structure.
[0040] It should be noted that the function of the disc 12 is to connect the two bent rods 10 so that the force is more evenly distributed when the workbench 3 is adjusted left and right, without causing unnecessary friction and collision between parts.
[0041] In this embodiment, a convex block is provided at one end of the bent rod 10 close to the disc 12, and the middle part of the bent rod 10 is rotatably connected to the support block 9. The two bent rods 10 are connected to the disc 12 having two through holes 3 through the convex block.
[0042] It should be noted that the function of the protrusion 13 is to clamp the disc 12 front and back to ensure the stability of the connection between the bent rod 10 and the disc 12. At the same time, the through hole three and the protruding block of the bent rod 10 should be clearance-fitted to ensure the stability of the device during movement.
[0043] In this embodiment, the front end of the steering wheel 15 is a circular ring structure, and the middle part is a shaft structure. Three round rods are provided at the front end of the shaft structure and are rotated about the axis of the shaft structure. The two ends of the round rods are fixedly mounted on the shaft structure and the circular ring structure respectively. Two snap rings are provided in the middle of the shaft structure, and the two snap rings are respectively located at the front and rear ends of the disc 12. A hexagonal protrusion 13 is provided at the rear end of the shaft structure, and can cooperate with the groove 1. The steering wheel 15 passes through the skateboard 8 and the disc 12 through the through hole 2 and the through hole 4, and is located just in front of the left roller 2.
[0044] It should be noted that the function of the clamping ring is to clamp at both ends of the disc 12, so that the front and rear ends of the steering wheel 15 are clamped. At the same time, the circular ring structure and the round rod of the steering wheel 15 ensure that the user can use it more labor-saving. The rotation of the steering wheel 15 can directly rotate the roller 2 and drive the adjustment structure to move left and right.
[0045] In summary, the magnetic workbench is provided with a curved rod 10 and a support block 9. When the steering wheel 15 is pushed backward, the square disc drives the circular disc 12 to move backward. At this time, due to the principle of leverage, the two opposite ends of the curved rods 10 move forward. At this time, the rear end of the steering wheel 15 is plugged into and engaged with the groove of the roller 2. At this time, the workbench 3 can be moved left and right by manually turning the steering wheel 15. The workbench 3 is moved to the left end until the first interface 6 is located directly behind the left input port 11. At this time, release your hands, and the protrusion 13 moves the two curved rods 1 due to the action of the spring 14. 0 is pushed forward, and at the same time, the input ports 11 set on the opposite ends of the two bent rods 10 move backward. At this time, the input port 11 on the left is in contact with the first interface 6, so that the workbench 3 is fed with excitation current, generating magnetic force to fix the workpiece. At the same time, the steering wheel 15 moves forward and separates from the groove of the roller 2. At this time, the fixation of the workpiece is completed. When disassembling the workpiece, the workbench 3 is moved to the right until the second interface 7 contacts the input port 11 on the right end. When the input port 11 is not in contact with the first interface 6 and the second interface 7, the device is in a rest state.
[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
