DETAILED DESCRIPTION

[0026] A machine tool constant pressure equipment provided by the utility model will be described in detail below in combination with the drawings and specific embodiments. Meanwhile, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best, preferred embodiments, and other alternative ways can also be adopted by the skilled in the art to implement some known technologies; and the drawings are only used to describe the embodiments more specifically, and are not intended to specifically limit the utility model.

[0027] As Figure 1 - Figure 7 shown, the embodiment of the utility model provides a machine tool constant pressure equipment, including: bottom plate 1;Buffer area 6, set up on bottom plate 1;Pump body 4, set up on buffer area 6;Connecting piece 8, the output end of being set up in pump body 4 is communicated;Conveying pipe 5, set up in connecting piece 8 is communicated;Connecting piece 8 includes outer layer 81, middle layer 82 and inner layer 83;Spiral groove 86, set up in middle layer 82, and close to inner layer 83;A plurality of flexible damping pieces 85, one end is set up in spiral groove 86, the other end is connected with inner layer 83, and flexible damping piece 85 is fan-shaped;Magnetorheological material 87, fill in flexible damping piece 85;Outer layer 81 is double-layer center shape;Electromagnetic coil 84, set up in outer layer 81.

[0028] The pressure sensor is arranged on the conveying pipe 5. When the pressure is too high, it means that the output or working condition of the pump body 4 abnormally fluctuates, the electromagnetic coil 84 increases the current, the magnetorheological material 87 is under the action of the strong magnetic field, the damping force of the flexible damping sheet 85 is rapidly increased, the vibration is strongly inhibited, and the flow rate and the pressure are rapidly returned to the normal track. Conversely, if the pressure is slightly low, the electromagnetic coil 84 appropriately reduces the current, the flexible damping sheet 85 is flexibly adapted, and it is ensured that the cooling liquid still flows smoothly and stably. The frequency converter is arranged on the pump body 4 and is electrically connected with the pressure sensor. By arranging the spiral groove 86, a relatively stable placement space can be provided for the flexible damping sheet 85, the position of the flexible damping sheet 85 is more fixed, when the pipeline vibrates, the flexible damping sheet 85 is subjected to extrusion and shearing action in the spiral groove 86, due to the limitation of the groove, the deformation direction and degree of the flexible damping sheet 85 can be controlled to some extent, so that the damping performance can be more effectively played.

[0029] By arranging the flexible damping sheet 85 in a fan shape, the deformation ability of the flexible damping sheet 85 in different directions is different when the pipeline vibrates, in the main vibration direction of the pipeline, more flexible damping sheets 85 with larger central angles can provide greater damping force, effectively inhibit the vibration in this direction, and the fan-shaped structure enables the flexible damping sheet 85 to generate shearing force in different directions during deformation. This multi-directional damping effect can better adapt to complex vibration conditions.

[0030] The inner layer 83 is composed of rubber material; the middle layer 82 is composed of stainless steel material. By arranging the inner layer 83, the main function of the rubber material is to provide flexible connection and preliminary buffering, which will be elastically deformed with the slight vibration and displacement of the pipeline. By arranging the middle layer 82, the stainless steel material provides firm support for the connecting piece 8, ensuring the structural integrity of the connecting piece 8 when it bears the pulsating pressure and the scouring of the cooling liquid for a long time. The outer layer 81 is made of protective material and has shielding effect, avoiding interference to the outside when the electromagnetic coil 84 works.

By arranging the soundproof frame 2, sound-absorbing materials such as sound-absorbing cotton, foamed plastic or other porous sound-absorbing materials are used. When the noise generated by the pump body 4 enters the sound-absorbing material, the sound wave causes the air in the pore to vibrate. Due to the friction between the air and the sound-absorbing material and the repeated compression and expansion of the air in the pore, the sound energy will gradually be converted into heat energy and consumed. The movable door is arranged on the soundproof frame 2, which is convenient for opening to replace or repair the internal equipment.

[0035] Further comprising: a slide rod 67 arranged in the mounting frame 61; two slide blocks 68 symmetrically arranged on the slide rod 67.

[0037] By arranging the tension spring 66, when the two slide blocks 68 move close to each other, the tension spring 66 is extruded to store elastic energy, when the two slide blocks 68 move away from each other, the tension spring 66 releases the elastic energy; by arranging the limiting cylinder 65, the deformation range of the tension spring 66 is limited, so as to avoid excessive stretching or compression of the spring when subjected to excessive force.
