DETAILED DESCRIPTION

[0021] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. It should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0023] like Figure 1 to Figure 2 As shown, a preferred embodiment of the utility model provides a hydraulic clamping device with a monitoring function, which includes a monitoring frame 1 and two groups of hydraulic monitoring mechanisms 2 that are symmetrically arranged on the left and right. The hydraulic monitoring mechanism 2 includes a hydraulic component 21, a clamping component 22, an infrared transmitter 23 and an infrared receiver 24. One end of the hydraulic component 21 is fixedly connected to the monitoring frame 1, the piston rod of the hydraulic component 21 is connected to the clamping component 22, the infrared transmitter 23 is fixed on the clamping component 22, and an infrared receiver 24 is provided above the infrared transmitter 23; when the piston rods of the left and right hydraulic components 21 are extended, the clamping component 22 can be driven to clamp the workpiece.

[0024] During operation, the hydraulic component 21 is driven to extend, and the clamping component 22 is driven to move synchronously, so as to clamp and fix the workpiece. By setting the infrared transmitter 23 and the infrared receiver 24, the clamping position of the clamping plate 221 can be detected when the clamping plate 221 is in a static clamping state, realizing the monitoring function, so that when the clamping side is offset, it can be discovered by the operator in time, avoiding the hydraulic pressure of the hydraulic cylinder 211 from being too low to cause contraction, ensuring the clamping effect, and also avoiding the occurrence of safety accidents. By adopting the utility model, the hydraulic clamping device has a monitoring function, ensuring the clamping effect, and avoiding the occurrence of safety accidents.

[0025] Exemplarily, the hydraulic assembly 21 includes a hydraulic cylinder 211 and a hydraulic pump 212, the hydraulic pump 212 is fixed on the monitoring frame 1, the hydraulic cylinder 211 is connected to the hydraulic pump 212, and a pressure sensor 213 is provided on the hydraulic assembly 21. In specific use, the hydraulic assembly 21 is used to ensure the clamping action of the clamping member on the workpiece, and the internal pressure of the hydraulic assembly 21 is detected by the pressure sensor 213, which can realize low-pressure detection of the hydraulic cylinder 211, thereby realizing a dual monitoring effect, further avoiding the hydraulic pressure of the hydraulic cylinder 211 being too low to cause contraction and affect the clamping effect.

[0026] For example, Figure 3 As shown, the clamping assembly 22 includes a clamping plate 221 and a suction cup 222. One end of the clamping plate 221 is connected to the hydraulic cylinder 211. The other end of the clamping plate 221 is provided with a first mounting groove 223. The suction cup 222 is fixed in the first mounting groove 223. The infrared emitter 23 is fixed on the upper end of the clamping plate 221. Through the provision of the suction cup 222, the clamping member of the hydraulic cylinder 211 can still be attracted to the workpiece in a loose state, so that the workpiece remains in a relatively stable state, thereby facilitating the continued clamping action after the workpiece is adjusted.

[0027] Exemplarily, in order to ensure the cooperation between the clamping plate 221 and the workpiece, an anti-slip pad 224 is provided at one end of the clamping plate 221 close to the suction cup 222 .

[0028] Exemplarily, a hydraulic clamping device with monitoring function also includes a magnetic suction component 25, the magnetic suction component 25 includes a metal plate 251 and an electromagnetic adsorption plate 252, the metal plate 251 is fixed on the clamping plate 221, the electromagnetic adsorption plate 252 is fixed on the hydraulic cylinder 211, and the metal plate 251 is connected with the electromagnetic adsorption plate 252. Through the cooperation of the metal plate 251 and the electromagnetic adsorption plate 252, the clamping plate 221 and the hydraulic cylinder 211 can be fixed, so that the clamping position can be installed, and it is also convenient for replacement.

[0029] It can be understood that when power is turned on, the electromagnetic adsorption plate 252 can generate magnetic force under the action of the coil, so that the metal plate 251 and the electromagnetic adsorption plate 252 attract each other, thereby realizing the connection between the clamping plate 221 and the hydraulic cylinder 211; when power is turned off, the electromagnetic adsorption plate 252 is separated from the metal plate 251, and the clamping plate 221 can be separated from the hydraulic cylinder 211.

[0030] In this embodiment, an insertion groove 253 for the hydraulic cylinder 211 to extend into is provided on one side of the clamping plate 221 facing the hydraulic cylinder 211 , and the metal plate 251 is fixed in the insertion groove 253 .

[0031] Specifically, the monitoring frame 1 includes an upper monitoring frame 11 and a lower monitoring frame 12, the upper monitoring frame 11 is plugged into the lower monitoring frame 12, and the upper ends of both sides of the lower monitoring frame 12 are provided with second mounting grooves 13, the hydraulic pump 212 is fixed in the second mounting grooves 13, and the hydraulic cylinder 211 is connected to the lower monitoring frame 12.

[0032] Exemplarily, the infrared receiver 24 is connected to the upper monitoring frame 111 through a pneumatic telescopic rod 26, and the telescopic end of the pneumatic telescopic rod 26 is fixedly connected to the infrared receiver 24; when the pneumatic telescopic rod 26 is extended, it can drive the infrared receiver 24 to move. During operation, the position of the infrared receiver 24 is adjusted according to the actual position of the infrared transmitter 23, so that the infrared transmitter 23 and the infrared receiver 24 are opposite to each other, so as to detect the clamping position of the clamping plate 221, and avoid the hydraulic pressure of the hydraulic cylinder 211 being too low to cause contraction, thereby affecting the clamping effect.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" 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 an indirect connection 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.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
