Description

Technical Field

[0001] The utility model relates to the technical field of correction fixtures, in particular to a correction fixture with a wedge-shaped chuck. Background Art

[0002] Melamine veneer, whose full name is melamine impregnated film paper veneer artificial board, is a decorative board made by soaking paper with different colors or textures in ecological board resin adhesive, then drying it to a certain degree of solidification, and laying it on the surface of particleboard, moisture-proof board, medium-density fiberboard, plywood, blockboard or other hard fiberboard, and then hot pressing it.

[0003] In the production of hot-pressed melamine board veneer, the melamine board substrate needs to be grabbed from the storage station, corrected, and then accurately placed on the board feed mechanism of the press to facilitate the press to laminat. Currently, most of the production methods are traditional, with manual handling of the board, which is labor-intensive and inefficient.

[0004] The existing mechanical grasping devices have the disadvantages of inaccurate calibration and high failure rate because their clamps are fixed or do not have the grasping ability. Therefore, the grasping reliability needs to be improved.

[0005] Therefore, for the melamine board substrate feeding correction grabbing operation, it is necessary to study a device with excellent performance and stable state to improve production efficiency. Utility Model Content

[0037] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0038] The connection method can be bonding, welding, bolt connection and other existing methods, depending on actual needs.

[0039] Example 1

[0040] See also Figures 1 to 9 In this embodiment, a correction fixture with a wedge-shaped chuck is provided.

[0041] The correction fixture 2 is installed together with the self-lubricating graphite copper sleeve 202 through the fixture guide rod 201. The self-lubricating graphite copper sleeve 202 is fixedly connected to the main body of the correction frame 1 by bolts. The fixture guide rod 201 can slide freely up and down along the axis of the self-lubricating graphite copper sleeve 202. A compression spring 203 is installed below the self-lubricating graphite copper sleeve 202, and the compression spring 203 is sleeved on the fixture guide rod 201 to provide a reset elastic force for the downward movement of the fixture guide rod 201 to prevent it from getting stuck. A nut is installed at the upper end of the fixture guide rod 201 to prevent it from getting loose, and the lower end is pressed against the fixture mounting rod 204 through the guide rod mounting plate 207. The guide rod mounting plate 207 is fixedly connected to the fixture mounting rod 204 by bolts.

[0042] Two calibration cylinders 206 are provided for each set of clamps, and are fixedly mounted on the clamp mounting rod 204 through a cylinder fixing seat 205. The cylinder fixing seat 205 and the clamp mounting rod 204 are fixedly connected by bolts.

[0043] A clamp roller 211 is installed on the clamp plate 208. The clamp plate 208 is connected to the clamp cylinder 213 through a Y joint. The slider of the linear guide rail 212 is installed on the clamp plate 208 through bolts. The clamp shaft 209 is installed on the mounting hole at the end of the clamp plate 208, and the clamp shaft 209 is installed with a hexagonal nut to prevent loosening. The clamp shaft 209 is installed in the round hole of the wedge chuck 210, and the wedge chuck 210 can rotate around the axis of the clamp shaft 209.

[0044] The linear guide rail 212 is mounted on the fixture mounting rod 204 by means of bolts, and is located between the clamping cylinder 213 and the fixture mounting rod 204 to save installation space.

[0045] The clamping cylinder 213 is a double-acting cylinder with its tail connected in series, and its two ends are connected to the clamping plate pulling plates 208 at both ends of the correction fixture 2 through Y joints.

[0046] Each set of correction 1 is equipped with two sets of correction fixtures 2, which are installed on both sides of the correction frame.

[0047] Here’s how it works:

[0048] When the utility model is used, the correction frame 1 reaches the storage position of the plate 3, the correction frame 1 descends, the correction fixture 2 and the fixture roller 211 contact the plate 3, and the correction fixture 2 is pressed on the surface of the plate 3 as a whole.

[0049] As the correction frame 1 continues to descend, the compression spring 203 of the correction fixture 2 is compressed, and the correction fixture 2 rises relative to the correction frame 1 along the axis direction of the fixture guide rod 201 until the correction frame 1 reaches the lower limit and stops. After the correction frame 1 reaches the lower limit, the clamping cylinder 213 of the correction fixture 2 is actuated and retracted, driving the wedge-shaped chuck 210 to retract inward along the linear guide rail 212, and the wedge-shaped chuck 210 clamps the plate 3. At this time, the wedge-shaped edge of the wedge-shaped chuck 210 clamps the middle position of the plate 3.

[0050] After the clamping is completed, the correction frame 1 grabs the plate 3 and rises together. After the grabbed plate 3 leaves the storage station, the cylinder rods of the correction cylinders 206 on both sides of the correction fixture 2 are pushed out at the same time and pressed against the clamp plate pull plate 208. The clamp plate pull plate 208 drives the wedge-shaped chuck 210 to automatically calibrate to the middle position. Finally, the Y-direction position calibration of the plate 3 relative to the correction frame 1 is completed, and the correction frame 1 moves to the plate placing station to place the plate.

[0051] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
