For example, a linear guide rail structure of a numerically controlled machine tool with the patent publication number CN203817772U includes a linear guide rail 1, a large carriage 2, and a small carriage 6. The linear guide rails 1 are symmetrically arranged on both sides of the upper surface of the large carriage 2.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In this application, a load-bearing inlaid steel guide rail and load-bearing rolling elements are arranged between the cross beam and the slide plate, breaking through the single sliding track or single rolling guide rail structure of the traditional guide rail, perfectly combining the rolling guide rail and the sliding guide rail, not only realizing the compounding of the structure, but also giving full play to the transmission advantages of these two guide rails. The main load-bearing guide rail of the cross beam adopts the cooperation of the load-bearing inlaid steel guide rail and the load-bearing rolling elements, which not only has high load-bearing capacity, high rigidity and wear resistance, but also the rolling elements and the inlaid steel guide rail have rolling friction, with a small friction coefficient, improving the response ability of the movement; the vertical guiding surface of the cross beam guide rail adopts a sliding hard rail, and the corresponding slide plate adopts a plastic-lined structure. Not only is the cross-sectional dimension of the slide rail design large, but the plastic-lined track surface has high wear characteristics and large shock absorption capacity; at the same time, an auxiliary load-bearing inlaid steel guide rail is arranged near the cutting processing area at the lower part of the cross beam, and the corresponding slide plate adopts an adjustable load-bearing rolling element for cooperation, which can further improve the stability during cutting processing and provide guarantee for the high-rigidity cutting of the machine tool.

[0016] 2. The movable end of the grating sensor is installed on the slide plate and the fixed end is installed on the cross beam, so that it can detect whether the slide plate moves. When the slide plate moves, the grating sensor is triggered and the solenoid valve is controlled by the PLC controller, so that the solenoid valve is opened and the air inlet pump is used for air inlet operation, so that the inside of the air delivery pipe receives gas and is respectively conveyed to each branch pipe, realizing the delivery of cooling gas. Among them, when the slide plate stops, it can be judged by the grating sensor and the solenoid valve is closed to end the delivery of cooling gas. Through the above structure, automatic cooling can be carried out during the movement of the slide plate, and the cooling ends when the slide plate stops. Among them, heat will be generated by the friction between the slide plate and the load-bearing inlaid steel guide rail during movement. In order to avoid the occurrence of slight deformation between the load-bearing inlaid steel guide rail and the cross beam due to heat change, through active cooling, the load-bearing inlaid steel guide rail and the cross beam can be in a stable temperature environment, thus avoiding the problem of the decrease in the movement accuracy of the slide plate or the service life of the load-bearing inlaid steel guide rail caused by slight deformation.

[0017] 3. Each load-bearing rolling element is in contact with the surface of the adjacent load-bearing inlaid steel guide rail and has a rolling friction movement. Among them, the heat dissipation exhaust port is arranged between every two load-bearing rolling elements, so that when the cooling gas is discharged from the heat dissipation exhaust port, the gas can dissipate heat from the load-bearing inlaid steel guide rail, which can avoid the accumulation of heat caused by the inability of the load-bearing inlaid steel guide rail to dissipate heat actively, and further avoid the occurrence of thermal deformation between the load-bearing inlaid steel guide rail and the cross beam, so as to ensure the stable operation of the slide plate under the continuous operation of the machine tool and avoid the decrease of the processing accuracy caused by thermal deformation.

[0018] 4. The motor can be started and stopped through the PLC controller, so that the control motor drives the lead screw to rotate. The moving frame is movably connected to the adjusting groove, and when the lead screw rotates, it is in threaded cooperation with the nut sleeve, so that the movement of the moving frame can be adjusted. A number of rubber pads are arranged at the bottom of the moving frame, and each rubber pad corresponds to the adjacent first through hole and the air inlet valve, so that when the air flow enters the air inlet valve, it will pass through a number of second through holes. The distribution density of the number of second through holes is set from high to low. When the moving frame moves, the flow rate of the air flow entering will be adjusted, so that the intensity of the cooling air flow can be adjusted as needed. When the air flow is modulated to the maximum, the air flow can be discharged from the heat dissipation outlet to clean the surface of the load-bearing hardened steel guide rail at the current position, so that the surface impurities will be discharged from one side, and the sliding plate is in a moving state to dissipate heat and assist in cleaning the passed position.

The main load-bearing guide rail of the cross beam 1 uses the cooperation of the load-bearing inlaid steel guide rail 5 and the load-bearing rolling elements 603, which not only has high load-bearing capacity, high rigidity, and wear resistance, but also the rolling elements and the inlaid steel guide rail have rolling friction, with a small friction coefficient, improving the response ability of the movement; the vertical guiding surface of the guide rail of the cross beam 1 uses a sliding hard rail, and the corresponding slide plate 2 uses a plastic-lined structure, not only the designed cross-sectional size of the slide rail is large, but also the plastic-lined rail surface has high wear characteristics and large shock absorption capacity; at the same time, an auxiliary load-bearing inlaid steel guide rail 5 is arranged near the cutting processing area at the lower part of the cross beam 1, and the corresponding slide plate 2 uses adjustable load-bearing rolling elements 603 for cooperation, which can further improve the stability during cutting processing and provide guarantee for high-rigidity cutting of the machine tool.

The three fixed housings 601 are respectively fixedly installed below the docking sleeve 21 and on the surfaces of the upper pressing plate 12 and the lower pressing plate 11. A rotating seat 602 is installed inside each fixed housing 601, and a number of load-bearing rolling elements 603 are installed inside the rotating seat 602. Each load-bearing rolling element 603 is in contact with the surface of the adjacent load-bearing hardened-steel guide rail 5; Adjustment grooves 604 and a number of diffusion grooves 6071 are respectively formed at the upper and lower ends on one side of the rotating seat 602. A partition plate 6072 is fixedly installed between the number of diffusion grooves 6071. A number of heat dissipation outlets 6022 are formed on one side of each diffusion groove 6071, and the heat dissipation outlets 6022 are distributed between two load-bearing rolling elements 603.

[0029] Since each load-bearing rolling element 603 is in contact with the surface of the adjacent load-bearing hardened-steel guide rail 5 and the movement therebetween is a rolling friction movement, and the heat dissipation outlets 6022 are arranged between every two load-bearing rolling elements 603, when the heat dissipation gas is discharged from the heat dissipation outlets 6022, the gas can dissipate heat from the load-bearing hardened-steel guide rail 5, which can prevent the load-bearing hardened-steel guide rail 5 from being unable to dissipate heat actively and causing heat accumulation, and further prevent the occurrence of thermal deformation between the load-bearing hardened-steel guide rail 5 and the cross beam 1, so as to ensure the stable operation of the sliding plate 2 when the machine tool is running continuously and avoid the decline of machining accuracy caused by thermal deformation.

[0030] In this application, a connecting sleeve 6011 is installed on one side of the fixed housing 601. The connecting sleeve 6011 is connected to the adjacent branch pipe 19. A transfer channel 6012 is formed inside the fixed housing 601, and the transfer channel 6012 is connected to the connecting sleeve 6011; A mating channel 6021 is formed on one side of the rotating seat 602. The mating channel 6021 is connected to the transfer channel 6012, and an extension pipe 606 is fixedly installed on one side of the mating channel 6021.

[0031] Among them, a ventilation pipe 6061 is fixedly installed inside the adjustment groove 604. The extension pipe 606 is connected to the ventilation pipe 6061, and a plurality of first through holes 6062 are opened at the lower end of the ventilation pipe 6061.

[0032] When the rotating seat 602 and the fixed shell 601 are combined, the cooperation channel 6021 is connected to the transfer channel 6012, so that the connecting sleeve 6011 can stably discharge the heat dissipation gas when connecting the branch pipe 19. And the ventilation pipe 6061 and a plurality of first through holes 6062 can all conduct gas transmission by using the extension pipe 606.

[0033] In this application, an intake valve 607 is fixedly installed at the upper end of each diffusion groove 6071. A moving frame 6054 is movably arranged inside the adjustment groove 604.

Since the moving frame 6054 is movably connected to the adjustment groove 604, and the lead screw 6052 rotates and is in threaded cooperation with the nut sleeve 6053 when rotating, the movement of the moving frame 6054 can be adjusted. Since a plurality of rubber pads 6055 are arranged at the bottom of the moving frame 6054, and each rubber pad 6055 corresponds to the adjacent first through holes 6062 and the intake valve 607, the air flow will pass through a plurality of second through holes 6056 when entering the intake valve 607. Since the distribution density of the plurality of second through holes 6056 is set from high to low, when the moving frame 6054 moves, the flow rate of the air flow entering will be adjusted, so that the intensity of the heat dissipation air flow can be adjusted according to needs. When the air flow modulation is the largest, the air flow can be discharged from the heat dissipation outlet 6022 to clean the surface of the load-bearing insert steel guide rail 5 at the current position, so that the surface impurities will be discharged from one side, and the slide plate 2 is in a moving state to perform heat dissipation and auxiliary cleaning treatment on the passing positions.

When the slide plate 2 moves, the grating sensor 20 is triggered and the solenoid valve 15 is controlled by the PLC controller 14, so that the solenoid valve 15 is opened and the air inlet pump 13 is used for air inlet operation, so that the inside of the air delivery pipe 17 receives gas and is respectively delivered to each branch pipe 19 to realize the delivery of heat dissipation gas; During heat dissipation, when the rotating seat 602 is combined with the fixed shell 601, the cooperation channel 6021 is connected to the transfer channel 6012, so that the connecting sleeve 6011 can stably discharge the heat dissipation gas when connecting the branch pipe 19, and the extension pipe 606 can make the ventilation pipe 6061 and a plurality of first through holes 6062 all conduct gas delivery; Before heat dissipation, according to needs, the PLC controller 14 can start and stop the control motor 605, so that the control motor 605 drives the screw rod 6052 to rotate. The movable frame 6054 is movably connected with the adjustment groove 604, and when the screw rod 6052 rotates, it is in threaded cooperation with the nut sleeve 6053, so that the movement of the movable frame 6054 can be adjusted. The bottom of the movable frame 6054 is provided with a plurality of rubber pads 6055, and each rubber pad 6055 corresponds to the adjacent first through hole 6062 and the air inlet valve 607, so that when the air flow enters the air inlet valve 607, it will pass through a plurality of second through holes 6056. The distribution density of the plurality of second through holes 6056 is set from high to low. When the movable frame 6054 moves, the flow rate of the air flow entering will be adjusted, so that the intensity of the heat dissipation air flow can be adjusted according to needs. When the air flow is modulated to the maximum, the air flow can be discharged from the heat dissipation outlet 6022 to clean the surface of the load-bearing steel-inlaid guide rail 5 at the current position; When the wind force is large, in order to prevent the air flow from not being discharged quickly, the baffle 6014 is pushed by the wind force to rotate the rotating shaft 6013, so that the discharge space can be temporarily enlarged, and the spring 6015 can cooperate with the rotating shaft 6013 to reset the baffle 6014 when the wind force decreases to prevent foreign impurities from entering.
