The track body 11 can be manufactured by adopting a process of hard oxidation of the surface of an aluminum alloy. The process of surface hardness oxidation can improve the hardness, wear resistance, insulation and other properties of the rail, which are known to those skilled in the art, and will not be described herein.

The rail through hole 12 may be a bolt hole for mounting a bolt, and the rail may be mounted on a device using the rail by passing the bolt through the rail through hole 12.

The section of the track groove 13 is trapezoid which gradually expands from inside to outside. The track groove 13 has a top surface 131, and first and second side surfaces 132, 133 on opposite sides of the top surface. The top surface 131, the first side surface 132, and the second side surface 133 form the track groove 13, and the track groove 13 is configured to abut the adjustable roller assembly 30 and the fixed roller assembly 40, and the ash removal baffle 50.

The sliding table 20 comprises a sliding table body 21, at least one kidney-shaped step hole 22 arranged on the sliding table body 21, at least one round step hole 23 arranged on the sliding table body 21, and a plurality of equipment through holes 24 arranged on the sliding table body 21. The slide body 21 is used for installing equipment such as a manipulator and the like which need to move along the track 10. Therefore, the structure of the slide table body 21 can be designed according to actual needs.

The kidney-shaped stepped hole 22 is a hole specially processed for adjusting the distance between the adjusting roller assembly 30 and the rail groove 13, which is a well known technology for those skilled in the art, and will not be described herein. The length direction of the kidney-shaped stepped hole 22 is perpendicular to the moving direction of the sliding table body 21. The working principle of the kidney-shaped stepped hole 22 and the adjustable roller assembly 30 to adjust the tightness between the adjustable roller assembly 30 and the rail groove 13 will be described below together with the adjustable roller assembly 30.

The circular stepped hole 23 is a hole specially formed for fixing the fixed roller assembly 40, which is a well known technology to those skilled in the art, and will not be described herein. The working principle of the circular stepped hole 23 to fix the fixed roller assembly 40 will be described below together with the fixed roller assembly 40.

The apparatus through hole 24 is provided on the slide table body 21. The device through hole 24 may be used to connect a power device, such as an engine, for driving the sliding table body 21 to move, which is a prior art and will not be described herein.

The adjustable roller assembly 30 comprises a roller 31 having an outer contour matching the rail groove 13, at least one rolling bearing 32 provided in the roller 31, an upper clamping block 33 provided in the kidney-shaped stepped hole 22, a lower clamping block 34 passing through the rolling bearing 32 and abutting against the kidney-shaped stepped hole 22, a first fixing screw 35 for fixing the upper and lower clamping blocks 33, 34 to the kidney-shaped stepped hole 22, and a second fixing screw 36 for providing the rolling bearing 32 to the lower clamping block 34.

The roller 31 may be made of a plastic material such as resin. The resin has the advantages of light material and abrasion resistance, thereby being capable of well prolonging the service life of the roller 31.

The rolling bearing 32 is a prior art, which is a precision mechanical element for changing the sliding friction of operation into rolling friction, thereby reducing friction loss, and is a well known technology for those skilled in the art, and will not be described herein. The rolling bearing 32 can change the sliding friction when the sliding table body 21 moves into the rolling friction when the roller 31 rotates through the lower clamping block 34 connected with the rolling bearing 32 and the sliding table body 21 in the moving process of the roller 31, so that the friction force born by the roller 31 becomes smaller. As the friction force applied to the roller 31 becomes smaller, the driving force required for the roller 31 becomes smaller, so that the moving speed of the slide table 21 becomes faster without changing the power of the apparatus. In this embodiment, the roller assembly 30 includes two rolling bearings 32, a spacer 37 is disposed between the two rolling bearings 32, and the spacer 37 is used to separate the two rolling bearings 32, so as to avoid mutual abrasion between the two rolling bearings 32 and thus affect the service life of the rolling bearings 32.

The dimension of the upper clamping block 33 perpendicular to the moving direction of the rail is smaller than the dimension of the waist-shaped stepped hole 22 in the length direction, so that the upper clamping block 33 can be adjusted in the waist-shaped stepped hole 22 in the direction perpendicular to the rail body 11 according to the requirement.

The lower clamp block 34 passes through the rolling bearing 32 and abuts against the waist-shaped stepped hole 22. The working principle of the upper clamping block 33, the lower clamping block 34, the kidney-shaped stepped hole 22, and the first fixing screw 35 for adjusting the tightness between the adjusting roller assembly 30 and the rail groove 13 will be described below together with the first fixing screw 35.

The first fixing screw 35 is used to fix the upper and lower clamp blocks 33, 34 to the kidney-shaped stepped hole 22. At this time, the regulating roller assembly 30 is fixed to the slide table body 21 by the first fixing screw 35. When the distance between the adjusting roller assembly 30 and the rail body 11 is not appropriate, the first fixing screw 35 may be loosened and then the positions of the upper and lower clamping blocks 33 and 34 and the kidney-shaped stepped hole 22 may be adjusted, so that the adjusting roller assembly 30 is tightly attached to the rail body 11, and after the position adjustment is completed, the first fixing screw 35 may be tightened again. In this way, the function of adjusting or compensating the slack between the roller assembly 30 and the rail body 11 is achieved.

The second fixing screw 36 is only used to fix the rolling bearing 22 on the lower clamping block 34, which is a prior art and will not be described in detail herein.

The stationary roller assembly 40 is a conventional technology, which is well known to those skilled in the art, and will not be described in detail herein.

The two ash cleaning scraping blades 51 are arranged on the ash cleaning baffle 50, and the outline of the ash cleaning scraping blades 51 is matched with the track groove 13 so as to achieve the purpose of full scraping. When the sliding table body 21 is driven to move by power, the adjusting roller assembly 30 and the fixed roller assembly 40, which are screwed with the sliding table body 21, also move. During the movement of the adjustment roller assembly 30, the rolling bearing 32 converts the sliding friction of the movement of the slide table body 21 into rolling friction of the rotation of the roller 31. The movement of the adjusting roller assembly 30 will drive the sliding table body 21 to move continuously, and the ash removal baffle 50 fixedly connected to the sliding table body 21 moves at this time. During the movement of the ash removal baffle 50, the ash removal scraper 51 can remove the accumulated ash in the track groove 13 contacted with the ash removal scraper 41 in a scraping manner, so that the running precision of the track is ensured. The ash removal baffle 50 is made of elastic materials, such as silica gel, rubber and the like, so that the ash removal baffle 50 has deformation capability, and the ash removal scraping blade 51 can be attached to the track groove 13 more tightly, so that the running precision of the track is further ensured.

Compared with the prior art, the guide rail with the gap compensation function provided by the utility model can adjust or compensate the gap between the adjusting roller assembly 40 and the rail 10 by utilizing the kidney-shaped step hole 22 and the upper and lower clamping blocks 33 and 34, so that the running precision of the rail can be ensured, and meanwhile, the ash removal baffle 50 arranged on the sliding table 20 can remove dust adhered to the rail 10 while the sliding table 20 runs, and the running precision of the rail can be further ensured. Specifically, since the length direction of the kidney-shaped stepped hole 22 is perpendicular to the moving direction of the sliding table 20, and the dimension of the upper clamping block 33 along the direction perpendicular to the moving direction of the sliding table 20 is smaller than the dimension of the kidney-shaped stepped hole 22 in the length direction, when adjustment is required, the relative position of the upper clamping block 33 and the kidney-shaped stepped hole 22 can be adjusted only by unscrewing the first fixing screw 35, so that the gap between the whole adjusting roller assembly 30 and the track 10 can be adjusted or compensated, and the purpose of adjusting the running accuracy of the track is achieved. For the ash removal baffle 50, since the ash removal scraping blade 51 with the outer contour matching with the track groove 13 is arranged on the ash removal baffle 50, when the sliding table 20 reciprocates, the ash removal scraping blade 51 can play a role in ash removal, thereby meeting the requirement of the user for ash removal.

The above is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model, and any modifications, equivalent substitutions or improvements within the spirit of the present utility model are intended to be covered by the claims of the present utility model.
