Description

Technical Field

[0001] The utility model relates to the technical field of sheet material clamping fixtures, in particular to a sheet material clamping fixture with high-precision positioning. Background Art

[0002] Sheet metal refers to a semi-finished product of smooth flat metal rolled from a slab. Its length and width are much greater than its thickness. When processing sheet metal, a fixture is an indispensable process equipment. During the processing, the fixture is used to position and clamp the workpiece to ensure that the workpiece maintains the correct position relative to the machine tool during the processing, which directly affects the accuracy, productivity and manufacturing cost of part processing.

[0003] Some existing clamps, for example, use a powerful air cylinder to drive two total arms to move the two total arms close to the clamp that clamps the sheet through a clamping plate. This type of clamp can only clamp the sheet in the center, which has great limitations and low precision. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a digital printing machine board module, which solves some of the existing clamps that exist today, such as a clamp that drives two total movable arms through a high-power cylinder to make the two total movable arms close to the clamp that clamps the sheet material through a clamping plate. This type of clamp can only clamp the sheet material in the center, which has large limitations and low precision.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-precision positioning sheet metal clamping fixture, comprising a mounting seat, two total arms are slidably arranged on the lower surface of the mounting seat, and multiple left clamping plates and right clamping plates are arranged on the two total arms, and the left clamping plates and the right clamping plates are located on the upper surface of the mounting seat, and the left clamping plates and the right clamping plates are symmetrical and staggered one by one. The lower surface of the mounting seat is fixedly connected to a fixing frame, and one side of the fixing frame is fixedly connected to a cylinder, and the cylinders are respectively fixedly connected to the two total arms, and the two cylinders face different directions.

[0006] In one example, sliding seats are fixedly provided on the upper surfaces of the two main movable arms, and all the sliding seats are arranged in an array. The sliding seats are slidably connected to sliding rails, and the sliding rails are fixedly connected to the mounting seats.

[0007] In one example, the sliding seats and the slide rails on the two total movable arms are tilted at the same tilt angle, and the two cylinders are tilted at the same tilt angle as the slide rails.

[0008] In one example, the total boom includes a transverse mounting plate, which is fixedly connected to a sliding seat, one side of the transverse mounting plate is fixedly connected to a vertical mounting plate, each of the vertical mounting plates is fixedly connected to a plurality of fixed seats, and a left clamping plate and a right clamping plate are fixedly connected to the upper surface of the mounting seat.

[0009] In one example, a slope is provided on one side of the left clamping plate opposite to the right clamping plate, and the slopes on the two left clamping plates are parallel to the slopes on the right clamping plate.

[0010] In one example, the inclination angle of all the slide rails, the slide seat and the cylinder is 45°.

[0011] In one example, the upper surface of the mounting seat is fixedly connected to multiple adsorption seats, all of the adsorption seats are arranged in an array, the left clamping plate and the right clamping plate are relatively located between two adsorption seats, all of the adsorption seats are provided with circular through holes, and a suction component is provided in the mounting seat, which is connected to the adsorption seat.

[0012] In one example, the suction assembly includes a circular pipe, which is located inside the mounting base. The circular pipe and the mounting base are both provided with a circular through groove connected to the circular through hole. One end of the circular pipe is fixedly connected to a pipe joint, and the other end of the pipe joint is connected to a vacuum device.

[0013] Beneficial effects of the utility model:

[0014] 1. Two cylinders are set to control two main arms respectively. When clamping, one cylinder can first drive the main arm to fix the position, then place the sheet, and then another cylinder drives another main arm to clamp the sheet. The two main arms operate separately, which is conducive to improving the clamping accuracy and can clamp different positions of the sheet, which is conducive to improving the flexibility of the device and expanding the scope of use of the device;

[0015] 2. By setting up an adsorption seat, when placing the sheet, the sheet is adsorbed by the adsorption seat, and then another cylinder drives another total arm to move, and the sheet is clamped and fixed by the left clamping plate and the right clamping plate. By setting up the adsorption seat, it can be avoided that when one cylinder drives the total arm to fix the position and the other cylinder drives the other total arm to move and clamp the sheet, the sheet is prevented from being skewed or detached from the upper surface of the mounting seat.

DETAILED DESCRIPTION

[0021] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0022] like Figure 1 to Figure 4 As shown, the embodiment of the utility model proposes a high-precision positioning sheet material clamping fixture, including a mounting seat 1, two total arms 2 are slidably arranged on the lower surface of the mounting seat 1, and a plurality of left clamping plates 3 and right clamping plates 4 are arranged on the two total arms 2, the left clamping plates 3 and the right clamping plates 4 are located on the upper surface of the mounting seat 1, the left clamping plates 3 and the right clamping plates 4 are symmetrical and staggered, the lower surface of the mounting seat 1 is fixedly connected to the fixing frame 5, one side of the fixing frame 5 is fixedly connected to the cylinder 6, the cylinder 6 is fixedly connected to the two total arms 2 respectively, the two cylinders 6 face different directions, the left clamping plate 3 and the right clamping plate 4 are opposite to each other. The inclined surfaces 9 are parallel to the inclined surfaces 9 on the two left clamping plates 3 and the right clamping plates 4, and the two cylinders 6 control one total arm 2 respectively. When clamping the plate, the two cylinders 6 drive one total arm 2 respectively. When sliding in opposite directions and the two total arms 2 gradually move away from each other, the left clamping plate 3 and the right clamping plate 4 are driven to move in opposite directions, and the inclined surfaces 9 on the left clamping plate 3 and the right clamping plate 4 are gradually approached to clamp and fix the middle plate. Most of the existing ones use a strong cylinder 6 to drive the two total arms 2 to move toward each other at the same time to clamp the plate. This method can only clamp the plate in the center. The present scheme controls the two total arms 2 respectively by setting two cylinders 6. When clamping, one cylinder 6 can first drive the total arm 2 to fix the position, and then place the plate, and then the other cylinder 6 drives the other total arm 2 to clamp the plate. The two total arms 2 operate separately, which is beneficial to improve the clamping accuracy, and can clamp different positions of the plate, which is beneficial to improve the flexibility of the device and increase the scope of use of the device.

[0023] like Figure 2 , Figure 3 and Figure 4As shown, sliding seats 7 are fixedly arranged on the upper surfaces of the two total arms 2, and all the sliding seats 7 are arranged in an array. The sliding seats 7 are slidably connected to the slide rails 8, and the slide rails 8 are fixedly connected to the mounting seat 1. The sliding seats 7 and the slide rails 8 on the two total arms 2 are tilted at the same inclination angle, and the two cylinders 6 are tilted at the same inclination angle as the slide rails 8. The inclination angle of all the slide rails 8, the sliding seats 7 and the cylinders 6 is 45°. Through the slide rails 8 and the sliding seats 7 with the same inclination angle, the moving directions of the two total arms 2 are made parallel, so that the two total arms 2 can drive the left clamping plate 3 and the right clamping plate 4 to clamp and fix the plate.

[0024] like Figure 3 and Figure 4 As shown, the total boom 2 includes a transverse mounting plate 21, which is fixedly connected to the sliding seat 7, one side of the transverse mounting plate 21 is fixedly connected to the vertical mounting plate 22, and multiple fixing seats 23 are fixedly connected to the vertical mounting plate 22, the left clamping plate 3 and the right clamping plate 4 are fixedly connected to the upper surface of the mounting seat 1, the transverse mounting plate 21 is located at the bottom of the mounting seat 1, the left clamping plate 3 and the right clamping plate 4 are installed on the vertical mounting plate 22, and are located on the surface of the mounting plate, the cylinder 6 drives the transverse mounting plate 21 to move, and the transverse mounting plate 21 drives the vertical mounting plate 22 to move to clamp the plate, and the equipment driving the left clamping plate 3 and the right clamping plate 4 is located below the mounting seat 1 to avoid occupying the area on the upper surface of the mounting seat 1 for clamping the plate.

[0025] like Figure 4 As shown, the upper surface of the mounting seat 1 is fixedly connected to a plurality of adsorption seats 10, and all the adsorption seats 10 are arranged in an array, the left clamping plate 3 and the right clamping plate 4 are located one by one between the two adsorption seats 10, and all the adsorption seats 10 are provided with circular through holes 11, and a suction component 12 is provided in the mounting seat 1, and the suction component 12 is connected to the adsorption seat 10, and the suction component 12 includes a circular pipe 121, and the circular pipe 121 is located inside the mounting seat 1, and the circular pipe 121 and the mounting seat 1 are provided with a circular through groove connected to the circular through hole 11, one end of the circular pipe 121 is fixedly connected to the pipe joint 122, and the other end of the pipe joint 122 is connected to the exhaust device, and is used When the vacuum device is used to evacuate air, suction is generated in the circular through hole 11 on the adsorption seat 10 through the circular pipe 121 and the circular through groove. When clamping the sheet material, one of the cylinders 6 can first drive the total arm 2 to fix the position, and then place the sheet material. The sheet material is adsorbed by the adsorption seat 10, and then the other total arm 2 is driven by another cylinder 6 to move, and the sheet material is clamped and fixed by the left clamping plate 3 and the right clamping plate 4. By setting the adsorption seat 10, it can be avoided that when one cylinder 6 drives the total arm 2 to fix the position and the other cylinder 6 drives the other total arm 2 to move to clamp the sheet material, the sheet material is prevented from being skewed or detached from the upper surface of the mounting seat 1.

[0026] The working principle and use process of the utility model are as follows: two cylinders 6 control a total arm 2 respectively. When clamping a plate, the two cylinders 6 drive a total arm 2 to slide in opposite directions respectively. When the two total arms 2 gradually move away from each other, the left clamping plate 3 and the right clamping plate 4 are driven to move in opposite directions. The inclined surfaces 9 on the left clamping plate 3 and the right clamping plate 4 gradually approach each other to clamp and fix the plate in the middle. Alternatively, one of the cylinders 6 can first drive the total arm 2 to fix the position, and then place the plate, and adsorb the plate through the adsorption seat 10, and then the other total arm 2 can be driven by the other cylinder 6 to move, and the plate can be clamped and fixed through the left clamping plate 3 and the right clamping plate 4.

[0027] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
