Description
Technical Field
[0001] The utility model belongs to the technical field of clamping tools, and particularly relates to an automatic clamping tool. Background Art
[0002] In the process of mechanical manufacturing, a device used to fix a processing object to make it occupy the correct position for construction or inspection is also called a fixture. Generally speaking, in any process of the technological process, a device used to quickly, conveniently and safely install a workpiece can be called a fixture. For example, welding fixtures, inspection fixtures, assembly fixtures, machine tools fixtures, etc. Among them, machine tool fixtures are the most common and are often simply referred to as fixtures. When machining a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the dimensions, geometric shapes and mutual position accuracies with other surfaces specified in the drawing, the workpiece must be installed and clamped firmly before machining.
[0003] In the prior art, the clamping tool for plate parts generally can only clamp the two sides, with poor clamping effect and low efficiency. And it is difficult to adjust the height after the clamping tool is installed. If there is a certain deviation during processing, generally the workpiece needs to be removed and fixed again, which is time-consuming and laborious and affects the efficiency. Therefore, an automatic clamping tool is improved and designed. Summary of the Utility Model
[0004] In view of the above deficiencies in the prior art, the utility model provides an automatic clamping tool to solve the problems in the above background art.

The plurality of clamping blocks are arranged in a circular array with the center of the base plate as the center of the circle; it further includes a linear actuator for driving the clamping blocks to approach or move away from the center of the base plate. The fixed end of the linear actuator is fixedly installed near the center of the base plate, and the movable end of the linear actuator is fixedly connected to the clamping block; it further includes a plurality of spacer blocks, and the spacer blocks are arranged between two adjacent clamping blocks.
[0007] By adopting the above structural design, the automatic clamping tool is used for automatically clamping a plate part. Specifically, the clamping tool includes a base plate, a plurality of clamping blocks movably installed on the base plate and a linear actuator for driving the clamping blocks to move. When in use, the plate part to be clamped is placed on the spacer blocks, and a plurality of linear actuators drive the clamping blocks to all move towards the center of the base plate, clamping the plate part on the spacer blocks from multiple directions, thereby realizing automatic clamping. Since a linear actuator is used for driving and clamping, when disassembling, the linear actuator is used again to drive the clamping blocks to move away from the center of the base plate, so that the plate part is disengaged from the clamping, and the plate part can be taken away, and the operation is very simple.
[0008] Further, the number of the cushion blocks and the clamping blocks is four each, and the cushion blocks are arranged near the edge of the substrate.

[0010] Further, the linear actuator is one of an electric telescopic rod or a hydraulic cylinder. In the actual implementation process, multiple linear actuators can be synchronously controlled to move by a controller, so that multiple linear actuators approach or move away from the center of the substrate simultaneously.
[0011] By adopting the above structural design, the clamping block of the automatic clamping tooling includes two L-shaped blocks, namely a first L-shaped block and a second L-shaped block as shown in the attached drawing.

The movable end of the linear actuator is fixedly connected to a shorter side of the second L-shaped block, and the top of the second L-shaped block is flush with the height of the cushion block. When clamping an object, the plate is located between the horizontal sides of the first L-shaped block and the second L-shaped block, and the vertical sides of multiple first L-shaped blocks press against the plate from different directions to form two groups of opposite clamping.
[0012] Further, a mounting seat is arranged on the substrate, and the linear actuator is fixedly installed on the mounting seat.
[0013] Further, it further includes a base. A connecting column is fixedly connected between the base and the substrate, and the number of the connecting columns is four. The four connecting columns are arranged in a circular array with the center of the substrate as the center of the circle.

[0026] Embodiment 1:
[0027] As Figures 1-3 shown, the present utility model. Specifically, an automatic clamping tooling includes a clamping tooling 1 for clamping a plate 01. The clamping tooling 1 includes a base plate 11 and a plurality of clamping blocks 13 movably installed on the base plate 11. The plurality of clamping blocks 13 are arranged in a circular array with the center of the base plate 11 as the center; it further includes a linear actuator 14 for driving the clamping blocks 13 to approach or move away from the center of the base plate 11. The fixed end of the linear actuator 14 is fixedly installed near the center of the base plate 11, and the movable end of the linear actuator 14 is fixedly connected to the clamping blocks 13; it further includes a plurality of spacer blocks 12, and the spacer blocks 12 are arranged between two adjacent clamping blocks 13. By adopting the above structural design, the automatic clamping tooling is used to automatically clamp the plate 01. Specifically, the clamping tooling 1 includes a base plate 11, a plurality of clamping blocks 13 movably installed on the base plate 11, and a linear actuator 14 for driving the clamping blocks 13 to move. When in use, the plate 01 to be clamped is placed on the spacer blocks 12, and the plurality of linear actuators 14 drive the clamping blocks 13 to all move towards the center of the base plate 11, and the plate 01 on the spacer blocks 12 is clamped from multiple directions, thus realizing automatic clamping. Since the linear actuator 14 is used for driving and clamping, when disassembling, the linear actuator 14 is used again to drive the clamping blocks 13 to move away from the center of the base plate 11, so that the plate 01 is disengaged from the clamping, and the plate 01 can be taken away. The operation is very simple.
[0028] In the actual implementation process, the number of spacer blocks 12 and clamping blocks 13 is four each, and the spacer blocks 12 are arranged near the edge of the substrate 11.

The movable end of the linear actuator 14 is fixedly connected to the shorter side of the second L-shaped block 132, and the top of the second L-shaped block 132 is flush with the height of the spacer block 12.
[0030] In the actual implementation process, the linear actuator 14 is one of an electric telescopic rod or a hydraulic cylinder. Multiple linear actuators 14 can be synchronously controlled to move by a controller, so that multiple linear actuators 14 approach or move away from the center of the substrate 11 at the same time. By adopting the above structural design, the clamping block 13 of the automatic clamping tooling includes two L-shaped blocks as shown in the attached drawing, namely the first L-shaped block 131 and the second L-shaped block 132. The first L-shaped block 131 is fixedly connected to the upper end of the longer side of the second L-shaped block 132. The movable end of the linear actuator 14 is fixedly connected to the shorter side of the second L-shaped block 132, and the top of the second L-shaped block 132 is flush with the height of the spacer block 12. When clamping an object, the plate 01 is located between the horizontal sides of the first L-shaped block 131 and the second L-shaped block 132, and the vertical sides of multiple first L-shaped blocks 131 press against the plate 01 from different directions to form two groups of opposite clamping.

Multiple linear actuators 14 drive the clamping block 13 to move towards the center of the substrate 11, and the plate 01 on the spacer block 12 is clamped from multiple directions, thereby realizing automatic clamping. Since the linear actuator 14 is used for driving and clamping, when disassembling, the linear actuator 14 is used again to drive the clamping block 13 to move away from the center of the substrate 11, so that the plate 01 is disengaged from the clamping, and then the plate 01 can be taken away. The operation is very simple.
