Description

[0033] like Figures 2 to 5 As shown, a rapid positioning support plate device comprises a gantry 1;

[0034] A Y-axis moving mechanism 2, which is arranged on the gantry 1;

[0035] A Z-axis lifting mechanism 3, which is arranged on the Y-axis moving mechanism 2;

[0036] The side-thrust mechanism 4 is arranged on the Z-axis lifting mechanism 3, and the side-thrust mechanism 4 includes a mounting member 41, a side-thrust cylinder 42 and a push plate 43. One end of the mounting member 41 is connected to the Z-axis lifting mechanism 3, and the other end thereof is connected to the side-thrust cylinder 42. The output end of the side-thrust cylinder 42 is connected to the push plate 43, so that: after the Y-axis moving mechanism 2 drives the side-thrust mechanism 4 to approach the workpiece 5 to be positioned, the Z-axis lifting mechanism 3 drives the side-thrust mechanism 4 to descend, and after the side-thrust cylinder 42 pushes out and drives the push plate 43 to contact the workpiece 5, it drives the workpiece 5 to move to the baffle 61 on the contact machine tool 6 to achieve positioning.

[0037] The rapid positioning device in the prior art is as follows Figure 1 As shown, at A, the device is positioning a large plate (large-sized workpiece); at B, the device is positioning a small plate (small-sized workpiece). As shown in the schematic diagram at B, when cutting a smaller workpiece, the cylinder and push plate on the side of the machine tool and the cylinder and push plate on the gantry are required to be driven in coordination to complete the positioning (the arrows indicate the first process, the second process and the third process when positioning the small plate). Since the above two groups of structures both use a fixed push plate cylinder structure, under the premise that there are large differences in the sizes of different workpieces being cut, the cylinder will need a longer stroke, and due to the influence of the installation space, the stroke of the cylinder is also limited, which will ultimately limit the positioning of the device when positioning the small plate.

[0038] In this solution, the side push mechanism 4 moves synchronously with the Y-axis moving mechanism 2 on the gantry 1 along the Y-axis. When the workpiece 5 is of the size to be positioned, the side push mechanism 4 is lowered to the side of the workpiece 5 along with the Z-axis lifting mechanism 3, and then the side push cylinder 42 is pushed out for positioning, and the cylinder drives the workpiece 5 on one side of the push plate 43 to perform a plate-backing action. This structure is different from the traditional fixed range size backing plate. The above device can realize full-size backing plate positioning, and can be positioned at any position on the Y-axis, so that the positioning of small workpieces 5 is no longer limited, and the above structure is relatively simple and easy to maintain.

[0039] The workpiece 5 may be a plate, that is, the rapid positioning plate support device of the present solution is particularly suitable for rapid positioning of various types of plates.

[0040] Furthermore, the mounting member 41 is provided with a reinforcing rib 411. In order to ensure the connection stability of the side thrust mechanism 4, the present solution provides a reinforcing rib 411 on the mounting member 41, the mounting member 41 is composed of a vertical plate and a horizontal plate, the reinforcing rib 411 is provided between the vertical plate and the horizontal plate, the reinforcing rib 411 is respectively connected to the vertical plate and the horizontal plate, the strength of the mounting member 41 is improved, and the side thrust mechanism 4 can be used for a long time.

[0041] Further, the Z-axis lifting mechanism 3 includes a first lifting component 31, and the side thrust mechanism 4 is arranged on the first lifting component 31;

[0042] The first lifting assembly 31 includes a first mounting frame 311, a first driving member 312, a first slider 313, a first slide rail 314 and a first mounting plate 315. The first mounting frame 311 is arranged on the Y-axis moving mechanism 2. The first driving member 312 is arranged on the first mounting frame 311, and its output end is connected to the first mounting plate 315. The first mounting frame 311 is provided with a vertical first slide rail 314. The first slider 313 is movably arranged on the first slide rail 314. The first mounting plate 315 is arranged on the first slider 313.

[0043] In the first lifting assembly 31, the first driving member 312 drives the side push mechanism 4 to perform lifting movement, so as to realize the rapid positioning of the workpiece 5. The first lifting assembly 31 can be a screw structure (the first driving member 312 is a motor in this case), which has the advantages of impact resistance, high reliability, high precision and convenient maintenance. The first lifting assembly 31 of the screw structure realizes the height adjustment of the side push mechanism 4. When the thickness of the workpiece 5 or the thickness of the pad under the workpiece 5 is inconsistent, the screw structure is convenient for adjusting the height of the side push mechanism 4 up and down.

[0044] Furthermore, the Z-axis lifting mechanism 3 further includes a second lifting assembly 32, the second lifting assembly 32 is arranged on the first mounting plate 315, and the side thrust mechanism 4 is arranged on the second lifting assembly 32;

[0045] The second lifting assembly 32 includes a second driving member 321, a second slider 322, a second slide rail 323 and a second mounting plate 324. The second driving member 321 is arranged on the first mounting plate 315, and its output end is connected to the second mounting plate 324. The first mounting plate 315 is also provided with a vertical second slide rail 323. The second slider 322 is movably arranged on the second slide rail 323, and the second mounting plate 324 is arranged on the second slider 322.

[0046] The second lifting assembly 32 is driven by the second driving member 321 to drive the entire second mounting plate 324 to be lifted and lowered along the second slide rail 323. When only the second lifting assembly 32 is set, the side push structure is set on the second mounting plate 324 and is lifted and lowered synchronously with the second mounting plate 324. The setting of the second lifting assembly 32 can expand the up and down stroke of the side push mechanism 4 in the Z-axis direction.

[0047] Furthermore, the Z-axis lifting mechanism 3 further includes a third lifting assembly 33, the third lifting assembly 33 is arranged on the second mounting plate 324, and the side thrust mechanism 4 is arranged on the third lifting assembly 33;

[0048] The third lifting assembly 33 includes a third driving member 331, a third slide rail 332, a third slider 333 and a connecting portion 334. The third driving member 331 is arranged on the second mounting plate 324, and the output end of the third driving member 331 is connected to the mounting member 41 through the connecting portion 334. The side of the second mounting plate 324 is provided with a vertical third slide rail 332. The third slider 333 is movably arranged on the third slide rail 332. The mounting member 41 is arranged on the third slider 333.

[0049] The Z-axis lifting mechanism 3 of the present solution includes three sets of lifting components, so that the height in the Z-axis direction can be adjusted, and can adapt to the effective positioning of workpieces 5 of various thicknesses.

[0050] The third driving member 331 of the third lifting assembly 33 is a lifting cylinder (mini cylinder) with a spring action, which can be freely raised and lowered, and has a small overall size and a short stroke. If the parameters of the entire device in the Z-axis direction are wrong, the third driving member 331 can be retracted under the action of external force to avoid damage caused by hard collision.

[0051] Furthermore, the Y-axis moving mechanism 2 includes a fourth driving member (servo motor), a fourth slide rail 21 and a fourth slider. The gantry 1 is provided with a transverse fourth slide rail 21. The fourth driving member is arranged on the gantry 1, and its output end is connected to the Z-axis lifting mechanism 3. The fourth slider is movably arranged on the fourth slide rail 21, and the Z-axis lifting mechanism 3 is arranged on the fourth slider. In the Y-axis moving mechanism 2, the fourth driving member drives the entire side thrust mechanism 4 to move along the fourth slide rail 21 on the Y-axis.

[0052] This solution does not use a Y-axis moving mechanism to push the plate, but instead uses a side push cylinder to push the plate. This is mainly because the actual width of the plate may vary, and there may be an error of several millimeters. If a servo motor is used to drive the plate directly against the plate and torque is used for identification, it is not easy to control whether the plate is in place.

[0053] Furthermore, both ends of the gantry 1 are provided with stoppers 11 for limiting the Z-axis lifting mechanism 3. In order to prevent the Z-axis lifting mechanism 3 and the side thrust mechanism 4 from moving beyond the limited stroke on the Y-axis, stoppers 11 are provided at both ends of the gantry 1. When reaching the limit stroke at both ends, the side of the Z-axis lifting mechanism 3 abuts against the stoppers 11 to prevent the Z-axis lifting mechanism 3 from continuing to move and achieve the limit. The structure is simple and the limit effect is good.

[0054] On the other hand, the utility model also provides a machining center, using any of the above-mentioned rapid positioning support plate devices. Figure 6 As shown, the machining center has the above-mentioned beneficial effects of the rapid positioning support plate device, which will not be described in detail here.

[0055] Furthermore, it also includes the machine tool 6; an X-axis moving mechanism, which is arranged on the machine tool 6, and the X-axis moving mechanism is provided with a fast positioning support plate device as described in any of the above items. Since the X-axis moving mechanism is additionally provided on the machine tool 6, the entire gantry 1 and the side thrust structure can be moved arbitrarily in the X-axis and Y-axis directions, so as to realize the fast positioning of the workpiece 5 at different positions on the machine tool 6. The X-axis moving mechanism can also be a cylinder, a slide rail and a slider structure.

[0056] Furthermore, the baffle 61 is provided on the side of the machine tool 6, and a lifting cylinder is also provided on the machine tool 6, and the output end of the lifting cylinder is connected to the baffle 61. The baffle 61 is usually arranged at the edge of the machine tool 6, and is used to prevent the plate 61 from moving to the outside of the machine tool 6. Since the thickness of the plate to be positioned may change, in order to adapt to the positioning of plates of more specifications, the baffle 61 is also arranged in a liftable form, and the baffle 61 is driven to rise and fall freely by the lifting cylinder. In this solution, the baffle 61 is usually arranged in a long strip shape, and two or three groups of lifting cylinders can be arranged under one baffle 61.

[0057] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
