In order to perfect the first guide rail set 3, in an embodiment, the first guide rail set 3 includes a plurality of first sliding blocks 302 and first sliding rails 301, the plurality of first sliding blocks 302 are slidably disposed on the first sliding rails 301, and the plurality of first sliding blocks 302 are connected with the grinding housing 601, it should be noted that in this scheme, each first sliding rail 301 is provided with two first sliding blocks 302, and the two first sliding blocks 302 are respectively connected with the edges of the front end and the rear end of the grinding bottom plate 1.
The key point of the embodiment is that the first guide rail group 3 comprises two first sliding blocks 302 and a first sliding rail 301, the grinding bottom plate 1 moves on the first sliding rail 301 through the two first sliding blocks 302, the first sliding rail 301 plays a role in guiding in the moving process of the grinding bottom plate 1, and the position of the grinding bottom plate 1 is prevented from shifting in the moving process; in addition, the first rail 301 also serves as a support during the movement of the grinding floor 1, since the first rail 301 has a very high load-carrying capacity for forces acting perpendicular to the rail surface. It should be noted that, because the grinding assembly 6 applies an additional vertical force to the front end of the grinding bottom plate 1 when the workpiece is ground by the grinding assembly 6, this can lead to deformation of the front end of the grinding bottom plate 1, in order to avoid deformation of the front end of the grinding bottom plate 1 due to excessive pressure, in this embodiment, each first sliding rail 301 is provided with two first sliding blocks 302, and the two first sliding blocks 302 are respectively connected with the edges of the front end and the rear end of the grinding bottom plate 1, when the workpiece is ground by the grinding assembly 6, the grinding assembly 6 can apply an additional vertical force to the front end of the grinding bottom plate 1, at this time, since the front end and the rear end of the grinding bottom plate 1 are respectively connected with the first sliding blocks 302, at this time, the force applied to the front end of the grinding bottom plate 1 is only shared to the whole grinding bottom plate 1, so that the force born by the front end of the grinding bottom plate 1 is greatly reduced, and deformation of the front end of the grinding bottom plate 1 due to excessive pressure is avoided.
In order to perfect the first slide rail 301, in an embodiment, the first slide rail 301 includes a slide rail housing 303 and a bearing block 304, the bearing block 304 is disposed in the slide rail housing 303, and a space is reserved between the slide rail housing 303 and the bearing block 304 for placing hydraulic oil, the slide rail housing 303 is connected with a hydraulic pump through an oil pipe, when the hydraulic pump injects hydraulic oil into the slide rail housing 303, the bearing block 304 disposed in the slide rail housing 303 is lifted up due to the increase of hydraulic oil until the bearing block 304 abuts against the first slide block 302, and at the moment, the hydraulic pump stops injecting hydraulic oil and keeps hydraulic oil in the slide rail housing 303, so that the bearing block 304 always keeps abutting against the first slide block 302; when the hydraulic pump pumps hydraulic oil out of the slide rail housing 303, the bearing block 304 arranged in the slide rail housing 303 is lowered due to the reduction of the hydraulic oil until the bearing block 304 is no longer propped against the first sliding block 302; in this way, the lifting of the carrier block 304 in the slide rail housing 303 is achieved.
The key point of the embodiment is that, because the sliding rail adopted by the first guide rail group 3 in the scheme is a ball linear sliding rail, the sliding rail has the advantages that a plurality of ball connections are arranged between the first sliding block 302 and the first sliding rail 301, and the sliding between the first sliding rail 301 and the first sliding block 302 is changed from the original surface friction to the linear friction in the connection mode, so that the friction resistance is greatly reduced, and the movement of the grinding mechanism arranged on the first guide rail group 3 is convenient; however, due to such design, the initial surface contact between the first slider 302 and the first sliding rail 301 is changed into the line contact, and the bottom surface of the first slider 302 is not abutted against the top surface of the first sliding rail 301, so that the contact area between the first slider 302 and the first sliding rail 301 is reduced, the bearing pressure in unit area is increased, especially, when the grinding assembly 6 is used for processing a workpiece, the grinding mechanism can generate a downward acting force, and at the moment, the pressure applied to the first slider 302 is larger, so that the structure of the first slider 302 is easy to deform irrecoverably.
Based on this, in order to not only reduce the sliding friction between the first slider 302 and the first sliding rail 301, but also avoid that the grinding assembly 6 has enough bearing area between the first slider 302 and the first sliding rail 301 when machining a workpiece, so that the acting force of the first slider 302 in the unit bearing area is reduced, therefore, the first sliding rail 301 in the scheme is composed of two parts of the sliding rail housing 303 and the bearing block 304, when the grinding assembly 6 needs to move, the first slider 302 does not abut against the bearing block 304 at this time, and at this time, the grinding assembly 6 can easily move because the friction between the first slider 302 and the first sliding rail 301 is linear friction; when the grinding assembly 6 needs to process a workpiece, at this time, the first sliding block 302 abuts against the bearing block 304, so that the contact area between the first sliding block 302 and the first sliding rail 301 is increased, the bearing pressure in unit area is reduced, at this time, the pressure born by the first sliding block 302 is reduced, the structure of the first sliding block 302 is not easy to deform in an irrecoverable manner, and the service life of the first sliding block 302 is better protected.
In addition, it should be noted that, when the top surface of the bearing block 304 abuts against the bottom surface of the first slider 302, the contact area between the first slider 302 and the first sliding rail 301 is increased, the bearing pressure in a unit area is reduced, and meanwhile, due to the fact that the top surface of the bearing block 304 is provided with a plurality of protrusions and the bottom surface of the first slider 302 is also provided with grooves matched with a plurality of protrusions, the static friction force between the bearing block 304 and the first slider 302 is increased, so that the relative position between the first slider 302 and the first sliding rail 301 can be stabilized when the grinding assembly 6 grinds a workpiece, and the machining precision of the grinding assembly 6 is ensured.
