In practice, the headgear 200 of the present invention is of a construction known to those skilled in the art and therefore will not be described in detail herein. In order to improve the control capability of the guideway platform 400 and precisely control the movement thereof, the present invention has been designed specifically for the guideway platform 400.
Specifically, as shown in fig. 1 and 3, the rail platform 400 includes: the grinding wheel machine comprises a platform body 410, an oil inlet pipe 420 and a guide rail seat 430 matched with a guide rail 110, wherein the platform body 410 is provided with a placing plane 411, a grinding wheel frame 300 is installed on the placing plane 411, the guide rail seat 430 is provided with a sliding guide groove 440, the oil inlet pipe 420 is communicated with the sliding guide groove 440, and the guide rail 110 part of a base 100 is accommodated in the sliding guide groove 440. In use, the grinding wheel carriage 300 is mounted on the rail platform 400, preferably, the grinding wheel carriage 300 is mounted on the placing plane 411 through bolts (not shown), and the placing plane 411 is provided with mounting through holes 412 matched with the bolts.
In this embodiment, as shown in fig. 4, 5 and 6, the slide guide groove 440 has three groove walls, an oil chamber 441 (shown in fig. 6) is opened on the groove wall of the slide guide groove 440, and the oil chamber 441 is communicated with the oil inlet pipe 420. When in use, hydraulic oil is injected into the oil chamber 441 through the oil inlet pipe 420, and an oil film is formed between the guide rail 110 and the groove wall of the sliding guide groove 440 to reduce friction force, and a specific working principle will be described below.
In the present embodiment, as shown in fig. 3, an oil storage tank 120 is opened on the base 100, and the oil storage tank 120 is used for collecting and storing the hydraulic oil overflowing from the oil chamber 441, so as to recycle the hydraulic oil later.
In the present embodiment, as shown in fig. 3, the driving device 500 includes a motor 510, a lead screw 520, and a nut holder 530. The motor 510 is mounted on the base 100, the nut holder 530 is in driving connection with the motor 510 through the lead screw 520, and the nut holder 530 is fixedly connected to the platform body 410. Preferably, one end of the screw 520 is connected to the motor 510 through a coupling 521, and the other end of the screw 520 is disposed on the base 100 through a bearing (not shown).
The working principle of the grinding machine 10 with hydraulic rail platform of the present invention will be explained below with reference to the embodiment:
when the device is installed, the guide rail platform 400 is installed on the guide rail 110 of the base 100, the guide rail 110 is partially accommodated in the sliding guide groove 440 of the guide rail seat 430, and at this time, three groove walls of the sliding guide groove 440 are in contact with the guide rail 110;
in operation, as shown in fig. 6 and 7, high-pressure hydraulic oil is injected from the oil pipe 420 into the oil chamber 441 of the rail base 430, so that the oil chamber 441 is filled with hydraulic oil. Because the guide rail 110 is pressed on the wall of the sliding guide groove 440, that is, the guide rail 110 covers the oil chamber 441, under the action of hydraulic pressure, the hydraulic oil will lift the guide rail 110 and overflow from the oil chamber 441, and finally flow into the oil storage groove 120 of the base 100;
after the hydraulic oil realizes stable circulation, a layer of stable oil film, namely a pressure oil film, is formed between the guide rail 110 and the oil chamber 441, so that the guide rail 110 is not in direct contact with the groove wall of the sliding guide groove 440 any more. When the motor 510 drives the screw 520 to rotate, the nut seat 530 can drive the guide rail platform 400 to move, and the guide rail platform 400 only needs to overcome a very small liquid friction force due to the existence of the pressure oil film. Therefore, the clamping pause of the guide rail platform 400 during movement can be reduced or even eliminated, so that the guide rail platform 400 can accurately move to a required position, and the processing precision of the grinding machine is improved.
It should be noted that, as shown in fig. 6 and 7, in the guide rail platform 400 of the present invention, the oil chambers 441 are distributed on three wall surfaces of the sliding guide groove 440, and hydraulic oil is injected into the oil chambers 441 from the oil pipe 420, so that pressure oil films can be formed on all three surfaces of the sliding guide groove 440, which are in contact with the guide rail 110, and thus, the guide rail 110 and the guide rail base 430 can be ensured not to be in direct contact. Moreover, the hydraulic oil is injected into the oil cavity 441 and overflows by adopting a high-pressure injection mode, instead of a traditional lubricating oil smearing mode, so that a pressure oil film formed between friction surfaces is more stable, and the pressure oil film is ensured to have a certain thickness and to be enough for supporting the guide rail platform 400 and the grinding wheel frame 300.
In one embodiment, as shown in fig. 6, an oil drainage groove 431 is further formed in the rail seat 430, and the oil drainage groove 431 is located between two groove walls of the sliding guide groove 440, so that the oil drainage groove 431 can guide the direction of overflowing hydraulic oil.
In one embodiment, as shown in fig. 2 and 3, the guide rail platform 400 includes an organ guard 450, and the organ guard 450 is disposed at both ends of the platform body 410, so that it is possible to prevent debris generated during processing from falling on the guide rail 110 and prevent hydraulic oil from being splashed out when the guide rail platform 400 moves.
In one embodiment, as shown in FIG. 1, the wheel carriage 300 is provided with a guard frame 320, and the grinding wheel 310 is partially received in the guard frame 320. Therefore, the object or the personnel can be prevented from mistakenly touching the grinding wheel 310 rotating at a high speed during working, and further safety accidents are prevented. Preferably, the grinding wheel carriage 300 is further provided with a hook 330, so that the grinding wheel carriage 300 can be conveniently lifted or carried when being installed.
In summary, according to the grinding machine 10 with the hydraulic guide rail platform, the guide rail platform 400 is prevented from being in direct contact with the guide rail 110, the friction force applied to the guide rail platform 440 during movement is reduced, the moving accuracy of the guide rail platform 400 is further improved, and the machining accuracy of the grinding machine is improved.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
