Technical Field
[0001] The utility model relates to the technical field of steel-wood furniture processing clamping devices, in particular to a steel-wood furniture processing clamping device. Background Art
[0002] In a fixture, the device used to prevent the workpiece from displacement or vibration during machining is called a clamping device. The following requirements should be considered when designing a clamping device:
[0003] 1. The position of the workpiece does not change during the clamping process.
[0004] 2. The clamping force should be large enough to ensure that the workpiece does not move or vibrate during processing, and does not damage the workpiece surface or cause deformation.
[0005] 3. Easy to operate and quick clamping action to improve productivity; simple structure and easy to manufacture to reduce the cost of the fixture.
[0006] 4. It can self-lock, that is, it can keep the workpiece clamped after the original force is removed.
[0007] 5. Safe operation and low labor intensity.
[0008] When clamping steel and wood furniture, clamping devices are often used for fixing.
[0009] The inventor discovered during daily use of the clamping device that when using the clamping assembly, since the furniture is placed directly on the surface of the workbench for clamping, the furniture may shift during clamping, causing the position of the furniture to change during clamping, making processing inconvenient and causing an impact.

[0010] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a steel-wood furniture processing clamping device.
[0011] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a steel and wood furniture processing clamping device, comprising a bracket, the upper top of the bracket is fixedly connected to an operating table, the side of the bracket is fixedly connected to a fixed plate, the upper top of the fixed plate is slidably connected to a cylinder, the upper top fixing block of the cylinder is connected to a hydraulic rod, one end of the hydraulic rod is fixedly connected to a pressure plate, the upper top of the pressure plate is provided with an extension device, the surface of the operating table is provided with a limiting device, the limiting device includes a through hole opened on the surface of the operating table, a connecting pipe is fixedly connected below the through hole, one end of the connecting pipe is fixedly connected to an air pump, and the air pump is fixedly connected to the inside of the bracket.
[0012] The effect achieved by the above components is: under the action of the connecting pipe and the air pump, the furniture can be limited after being placed on the surface of the workbench, so that it will not shift during clamping. When the furniture needs to be clamped, the furniture is placed on the surface of the workbench, the cylinder is slid to the appropriate position on the surface of the fixed plate, and the cylinder is started, so that the hydraulic rod drives the pressure plate to move downward, thereby clamping and fixing the furniture.
[0013] Preferably, a baffle is fixedly connected to the inner wall of the through hole, a first spring is fixedly connected to the bottom of the baffle, and a locking ball is fixedly connected to one end of the first spring.
[0014] The effect achieved by the above components is: under the action of the card ball, the air between the furniture and the workbench is sucked away, and the card ball is reset under the action of the first spring, thereby sucking the furniture onto the surface of the workbench to limit its position.
[0015] Preferably, a round cover is inserted into the through hole, and a round ball is fixedly connected to the top of the round cover.
[0016] The effect achieved by the above components is that, under the action of the round cover, debris will not fall into the through hole and block the through hole.
[0017] Preferably, a snap ring is fixedly connected to the surface of the round cover, and the snap ring is a rubber ring.
[0018] The effect achieved by the above components is as follows: under the action of the clamping ring, the round cover can be firmly stuck in the through hole. When the furniture needs to be fixed, the round cover is pulled out, the furniture is placed on the surface of the workbench, and the air pump is started to discharge the gas through the connecting pipe. Under the action of the clamping ball, the air between the furniture and the workbench is sucked away. The clamping ball is reset under the action of the first spring, and then the furniture is sucked to the surface of the workbench for limiting the position, thereby achieving the limiting effect.
[0019] Preferably, the extension device includes a hinge rotatably connected to one end of the pressure plate, and one end of the hinge is fixedly connected to an extension rod.
[0020] The effect achieved by the above components is that under the action of the extension rod, the pressing plate can squeeze furniture of different sizes, avoiding the phenomenon that the furniture is too small to be squeezed.
[0021] Preferably, a rectangular strip is fixedly connected to the surface of the extension rod, and the rectangular strip is a rubber strip.
[0022] The effect achieved by the above components is that, under the action of the rectangular strip, the extension rod will not directly contact the furniture, thus avoiding the phenomenon of furniture being damaged due to squeezing overload.
[0023] Preferably, a rectangular plate is fixedly connected to the side surface of the extension rod, a clamping rod is inserted into the side surface of the rectangular plate, and a circular groove is opened on the side surface of the pressure plate.
[0024] The effect achieved by the above components is that under the action of the clamping rod, the extension rod can be fixed on one side of the pressure plate.
[0025] Preferably, a second spring is sleeved on the surface of the clamping rod, and two ends of the second spring are fixedly connected to the rectangular plate and one end of the clamping rod respectively.
[0026] The effect achieved by the above components is: under the action of the second spring, the clamping rod is self-locking and inserted into the circular groove for fixation. When smaller furniture needs to be clamped, one end of the extension rod is fitted together with one end of the pressure plate through the hinge. Under the action of the second spring, the clamping rod is self-locking and inserted into the circular groove for fixation. Under the action of the rectangular bar, the extension rod will not directly contact the furniture, avoiding the phenomenon of damage to the furniture caused by extrusion overload, thereby achieving the extension effect and avoiding the pressure plate from being unable to clamp smaller furniture.
[0027] Compared with the prior art, the advantages and positive effects of the present invention are:
[0028] In the utility model, by providing a limiting device, when it is necessary to fix the furniture, the round cover is pulled out, the furniture is placed on the surface of the operating table, the air pump is started to discharge the gas through the connecting pipe, and under the action of the locking ball, the air between the furniture and the operating table is sucked away, and the locking ball is reset under the action of the first spring, and then the furniture is sucked onto the surface of the operating table for limiting, thereby achieving the limiting effect, thereby solving the problem that the furniture cannot be limited before being clamped.
