Description

Technical Field

[0001] The utility model relates to the field of static pressure guide rails, in particular to a static pressure guide rail with a protective device. Background Art

[0002] The hydrostatic guide rail forms a load-bearing oil film by inputting lubricating oil with a certain pressure into the oil cavity on the guide rail surface through a throttle, so that the guide rail surfaces are in a pure liquid friction state. The guide rail sliding friction coefficient is lower and the stability is better. Therefore, it is widely used in various precision equipment. With the development of industry, more and more hydrostatic guide rails are produced and applied, such as the double V-shaped liquid hydrostatic guide rail disclosed by the China Patent Network (public announcement number CN217045408U). The hydrostatic guide rail of this type of device is provided with a cooling mechanism, and the coolant is continuously fed into the cooling pipe through an external cooling device. The coolant is in the serpentine pipe of the cooling pipe. During the flow process, the winding setting of the pipe increases the coolant retention time, so that the coolant can take away more heat conducted on the heat absorbing plate, thereby reducing the temperature of the hydraulic oil inside the slider, and thus reducing the frequency of hydraulic system failures caused by overheating of the hydraulic oil.

[0003] However, the hydrostatic guide rails described in the aforementioned patents and currently used in the market still have some shortcomings. The existing method of using external devices to achieve hydrostatic guide rail temperature protection has high installation and operating costs and significant limitations. Furthermore, when the hydrostatic guide rail has a long braking distance, the connection between the external device and the hydrostatic guide rail becomes cumbersome. Therefore, those skilled in the art have provided a hydrostatic guide rail with a protective device to address the issues raised in the above-mentioned background art. Utility Model Content

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A static pressure guide rail with a protective device includes a bottom support platform;

[0006] The guide rails are symmetrically arranged above the frame of the bottom support platform, and the guide rails of each set of guide rails are slidably connected to the guide platform;

[0007] A heat conducting plate is installed between the two opposite groups of guide slides, and a refrigeration plate is installed below the plate frame of the heat conducting plate;

[0008] A heat conducting coil is installed inside the plate frame of the heat conducting plate, and a cooling coil is installed inside the plate frame of the refrigeration plate, and the cooling coil and the heat conducting coil are connected through a circulation pump installed on the side wall of the refrigeration plate;

[0009] A plurality of cooling fans are arranged on one side of the plate frame of the cooling plate, and a transmission shaft opposite to the cooling fans is arranged inside the plate frame of the cooling plate;

[0010] A braking mechanism for driving a circulating pump and a cooling fan is provided between the bottom support platform and the refrigeration plate.

[0011] As a further technical solution of the present invention: the braking mechanism includes a brake rack installed on the bottom support platform along the direction of the guide slide rail and a brake gear installed on the side wall of the refrigeration plate, and the brake rack and the brake gear are engaged with each other for transmission. One side of the brake gear is engaged with the first differential gear A, and the first differential gear A is engaged with the first differential gear B installed at one end of the transmission shaft rod for transmission. The other side of the brake gear is engaged with the second differential gear A, and the second differential gear A is engaged with the second differential gear B installed on the pump shaft of the circulating pump for transmission.

[0012] As a further technical solution of the present invention: the tooth length of the braking rack is the same as the guide rail length of the guide rail.

[0013] As a further technical solution of the present invention: a transmission worm gear is installed on the central axis of the blades of each group of cooling fans, and the shaft of the transmission shaft is arranged with transmission worms that are opposite to the transmission worm gears one by one.

[0014] As a further technical solution of the present invention: the heat-conducting coil and the cooling coil are both U-shaped coil structures, and the plate frame of the heat-conducting plate is filled with a heat-conducting medium that wraps the heat-conducting coil.

[0015] As a further technical solution of the present invention: the bottom frame of the refrigeration plate is provided with a ventilation window.

[0016] The utility model provides a static pressure guide rail with a protective device, which has the following advantages compared with the prior art.

[0017] Beneficial effects:

[0018] The hydrostatic guide rail of this design is based on the passive transmission of the braking mechanism. When the hydrostatic guide rail slides, it operates synchronously. On the one hand, it controls the braking of the circulating pump to circulate the coolant in the cooling coil into the heat transfer coil. By utilizing the direct contact between the heat transfer plate and the guide slide, the guide slide is cooled and cooled to avoid excessive oil pressure of the lubricating oil in the guide slide, dripping, seepage, etc., thereby improving the operation stability of the hydrostatic guide rail. On the other hand, it controls the operation of the cooling fan to drive the external cold air circulation to cool the cooling coil, forming a self-operating cooling protection state. The self-protection work of the hydrostatic guide rail can be completed without external equipment. The installation cost is lower and the installation limitation is smaller.

The tooth length of the brake rack 8 is the same as the guide rail length of the guide slide 2. When the combination of the guide slide 3 and the support platform 4 slides along the guide slide 2, it drives the combination of the heat conduction plate 5 and the refrigeration plate 6 to slide synchronously, and then drives the brake gear 9 to slide synchronously. By utilizing the meshing transmission of the brake gear 9 and the brake rack 8, the brake gear 9 keeps rotating while sliding. As a driving source, on the one hand, it utilizes the meshing transmission with the first differential gear A10 and the first differential gear B11 to promote the linkage operation of the combination of the drive shaft 19 and the cooling fan 7.
