The shortcoming of this utility model is that the nuts of the device are limited by the nut placement seats, which has a limited tightening effect on the nuts. Summary of the Invention

[0004] The present invention aims to overcome the drawback in the prior art that placing nuts through placement grooves may easily lead to inadequate fastening effects, and provides a nut plate tapping fixture that clamps the nut plate through a lifting fixture.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A fixture for tapping a nut plate, comprising: Workbench; A support platform, wherein a working chamber is provided on the support platform; A clamping assembly, the clamping assembly being mounted at the upper end of the working chamber and being slidably connected to the support platform; A lifting assembly, the lifting assembly being placed in the working chamber and mounted on a workbench, the lifting assembly being detachably connected to the clamping assembly; A waste collection assembly, the waste collection assembly being mounted on the lifting assembly and corresponding to the clamping assembly; A grabbing assembly, the grabbing assembly is placed on one side of the support table and mounted on the workbench, the grabbing assembly corresponding to the clamping assembly; An arranging component is placed on the other side of the supporting platform and installed on the workbench.

[0006] The workbench is used to install the overall structure, and the nut plate is supported by a support platform installed on the workbench, and the nut plate is placed on the clamping assembly installed at the top of the working chamber of the support platform, and the clamping assembly is driven to rise and fall in the working chamber by the lifting assembly, and the nut plate is clamped by the lifting of the clamping assembly, and then the tapping machine corresponding to one side of the workbench is used for tapping. The tapping machine is an existing technology, which can correspond to the clamping assembly, and the clamping assembly is detachably connected to the lifting assembly, so that the clamping assembly can be disassembled and replaced. During the processing, the waste falling during the tapping process is collected by the waste collection assembly installed on the lifting assembly, thereby reducing the accumulation of waste in the dry working chamber, and a grabbing assembly is installed on one side of the support platform, which can be used to grab the processed nut plate, reducing manual operation and quickly removing the nut plate, and the arranging assembly installed on the other side can arrange and place the unprocessed nut plates, which is convenient for taking and placing, thereby achieving the purpose of clamping the nut plate by the lifting clamp.

[0007] Preferably, the support platform includes a mounting bar, a support block, and a lifting tube. The mounting bar is mounted on the bottom surface of the support block, the mounting bar is connected to the workbench, the lifting tube is mounted on the top of the support block, the working cavity passes through the support platform, and the lifting tube is connected to the support block. The support block of the support platform is mounted on the workbench via the mounting bar, the working cavity passes through the support block and is connected to the remaining lifting tube. A lifting assembly is mounted in the working cavity, and a clamping assembly is mounted in the lifting tube. The lifting tube is lifted by the support platform, and the lifting assembly is installed inside. This protects the lifting assembly, increases its service life, and ensures the stability of the support platform. This design can protect the internal devices.

[0008] Preferably, the clamping assembly includes a load-bearing column and a clamping column, the load-bearing column is placed in the lifting tube and is slidably connected to the lifting tube, the clamping column is truncated in shape, the end of the clamping column with a smaller diameter corresponds to the load-bearing column and is connected to the load-bearing column, the clamping assembly is provided with a through hole, the top surface of the clamping column is installed with a placement groove, and the clamping column is provided with a plurality of closing grooves distributed in a circumference. The force-bearing column of the clamping assembly is placed in the lifting tube and the diameters of the two are consistent, ensuring a smooth lifting process. The clamping column is driven to rise and fall by the force-bearing column, and the nut plate is placed in the placement groove at the top of the clamping column. Then the force-bearing column drives the clamping column to descend. Since the shape of the clamping column is truncated, the diameter of the upper end of the clamping column is larger than the diameter of the lifting tube. Since a closing groove is provided on the clamping column, the upper end of the clamping column can slide. In the process of the force-bearing column driving the clamping column to descend, the diameter of the clamping column will be squeezed to be consistent with the lifting tube, and the nut plate is clamped by closing the upper end of the clamping column inward to ensure the stability of the nut plate. The through hole opened on the clamping assembly facilitates the descent of the tapping drill bit and chip removal, and the nut plate can also be released after the clamping assembly rises. This design can fix the nut plate.

[0009] Preferably, the lifting assembly includes a pneumatic cylinder 1 and a connecting frame, the pneumatic cylinder 1 is installed on a workbench, the connecting frame includes a lifting plate and a connecting rod, the lifting plate is connected to the pneumatic end of the pneumatic cylinder 1, the connecting rod is provided with a plurality of connecting rods and distributed in a circumference, the lower end of the connecting rod is connected to the lifting plate, and the upper end of the connecting rod is detachably connected to the bottom surface of the load-bearing column. The lifting assembly installed in the working chamber drives the connecting frame to rise and fall through the pneumatic cylinder 1, the lifting plate of the connecting frame is connected to the pneumatic end of the pneumatic cylinder 1, the lifting plate is connected to the bottom surface of the load-bearing column through the connecting rod, and drives the load-bearing column to rise and fall through the connecting column, and external force is applied to the load-bearing column through a plurality of evenly distributed connecting plates, so that the force of the load-bearing column can be balanced, ensuring that the clamping assembly can stably clamp the nut plate. Such a design can lift and lower the clamping assembly.

[0010] Preferably, a buckling plate is installed on the upper end of the connecting rod, and the buckling plate is fitted with the bottom surface of the load-bearing column. The bottom surface of the load-bearing column is installed with a plurality of fitting rings distributed in a circle, and the fitting rings correspond to the buckling plate one by one. The cross-sectional shape of the fitting ring is semicircular, and the fitting ring is fitted with the buckling plate. The bottom surface of the fitting ring is installed with a fixing plate, and the fixing plate is provided with a screwing groove, and the screwing groove matches the connecting rod. In order to replace and repair the clamping assembly, as well as to clean the working chamber, a buckling plate is installed at the top of the connecting plate. When installing the clamping assembly and connecting it with the lifting assembly, the bottom surface of the load-bearing column is fitted with the buckling plate, and then the clamping assembly is screwed. The load-bearing column rotates, and the buckling is rotated to fit with the fitting ring to limit the position of the load-bearing column. In the process of fitting the fitting plate and the buckling plate, the connecting rod rotates along the screwing groove of the fixed plate to fit the bottom surface of the buckling plate with the fixed plate, and the buckling plate is restricted between the fixed plate and the bottom surface of the load-bearing column to ensure that the buckling plate and the load-bearing column are fitted. The clamping assembly and the lifting assembly can be disassembled and assembled by rotating the clamping assembly. Such a design allows for disassembly and assembly of the clamping assembly.

[0011] Preferably, the waste collection assembly includes a collection bucket, which is placed on a lifting plate. The collection bucket corresponds to the through-hole of the clamping assembly. The lifting plate is provided with a plurality of circumferentially distributed limit blocks, which fit in with the side of the collection bucket. The collection bucket of the waste collection assembly is placed on the lifting plate of the lifting assembly, and receives debris from the tapping process by corresponding to the through-hole of the clamping assembly. In order to ensure that the collection bucket corresponds to the clamping assembly, a limit block is installed on the lifting plate. The limit block fits in with the side of the collection bucket, which can limit the collection bucket and ensure that the position of the collection bucket corresponds to the clamping assembly. Such a design can collect debris.

[0012] Preferably, an annular groove is installed on the inner wall of the collection bucket, and the cross-sectional shape of the annular groove is triangular. A lifting ring is provided on the inner wall of the collection bucket, and the shape of the lifting ring is circular arc. The two ends of the lifting ring are respectively connected to the rotation of the two sides of the collection bucket. A placement block is installed on the inner wall of the collection bucket, and the placement block corresponds to the collection bucket. Since the diameter of the lifting tube is small, it is not easy to take the collection bucket in and out. Therefore, an annular groove is installed on the inner wall of the collection bucket. The annular placement rod can correspond to the collection bucket, so that the collection bucket can be placed on the lifting plate to limit the position. The triangular shape of the annular groove can also quickly separate the placement rod and the collection bucket, so that the collection bucket can be accurately placed. When the collection bucket needs to be removed, it can be quickly removed by connecting it to the lifting ring through a hook. In order to facilitate the connection of the hook to the lifting ring, one side of the lifting ring is placed on the placement block to facilitate connection with the hook.

After the tapping machine has finished processing the nut plate, the clamping assembly releases the fixation of the nut plate, and one end of the L-shaped rotating rod corresponds to the clamping assembly. A flat plate is installed on the rotating rod, and the pneumatic cylinder 2 installed on the flat plate drives the bonding plate to fit the top surface of the clamping assembly, and then the electric push rod of the telescopic assembly is retracted, driving the U-shaped telescopic rod to move inward along the sliding groove on the bonding plate, and the corresponding side of the telescopic rod and the clamping assembly is inserted into the closing groove, and one side of the telescopic rod is placed under the nut plate, and several evenly distributed telescopic assemblies are placed under the nut plate to lower the nut plate and limit the nut plate to ensure that the nut plate is placed between the telescopic rods, and then the pneumatic cylinder 2 drives the bonding plate to rise, and drives the nut plate to rise away from the clamping assembly through the telescopic rod. This design can lift the nut plate.

[0014] Preferably, the rotating rod is mounted with a first gear, the workbench is mounted with a first motor, the motor shaft of the first motor is mounted with a second gear, and the first gear meshes with the second gear. After the nut plate is lifted, the nut plate needs to be moved. At this time, the first motor is activated, driving the second gear to rotate.
