Description

Technical Field

[0002] The linear guide rail is a precision component in a machine tool, generally used in high-precision or high-speed linear reciprocating motion occasions. After the linear guide rail and the first slider are assembled, it is necessary to measure their parallelism. Taking a 1-meter-long guide rail as an example, the parallelism requirement is within 0.01 mm. When the parallelism is unqualified after the assembly of the linear guide rail and the first slider, it is necessary to grind the bottom surface of the linear guide rail.

Since the feed of this method for grinding the linear guide rail is uneven, the accuracy of the bottom surface of the ground linear guide rail cannot meet the requirements, and there are certain safety hazards in manually pushing the linear guide rail.

Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

If this specific posture changes, the directional indications will also change accordingly.

[0033] In addition, the descriptions involving "first", "second", etc. in the present application are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0034] By providing a grinding mechanism for the bottom surface of a linear guide rail in the embodiments of the present application, the technical problems of insufficient precision and safety in manual grinding of the guide rail in the prior art are solved.

[0035] The overall idea of the technical solutions in the embodiments of the present application to solve the above technical problems is as follows:

[0036] As Figures 1-5 shown, the present application provides a grinding mechanism for the bottom surface of a linear guide rail, including:

[0037] A bed surface 100, on which a grinding mechanism 200 is installed;

[0038] A propulsion mechanism 1, which includes a driving component and a fixed platform 14. The driving component is installed on the bed surface 100, and the fixed platform 14 is installed on the driving component;

[0039] A push rod mechanism 2, which clamps the guide rail 300 and is correspondingly arranged at the output end of the grinding mechanism 200. The push rod mechanism 2 is installed on the fixed platform 14, and the driving component is used to drive the guide rail 300 to translate.

[0040] The grinding mechanism 200 is fixedly installed on the bed surface 100. The propulsion mechanism 1 drives the guide rail 300 to move horizontally, so that the grinding mechanism 200 grinds the plane of the guide rail 300, enabling the guide rail 300 to be fed evenly, improving the grinding precision of the bottom surface of the guide rail, and reducing the safety hazards of manual operation.

[0041] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0042] Preferably, asFigures 1-4 As shown, the driving assembly includes a base 11, a first slide rail 12, a first slider 13, and a translation motor 15. The base 11 is installed on the bed surface 100, the first slide rail 12 is installed on the base 11, the first slider 13 is slidably arranged on the first slide rail 12, the fixed platform 14 is installed on the first slider 13, a rack 16 is fixedly arranged on the base 11, the translation motor 15 is installed on the fixed platform 14, and the output shaft of the translation motor 15 meshes with the rack 16 through a gear 17. In this embodiment, the output shaft of the translation motor 15 cooperates with the rack 16 through a helical gear 17.

[0043] When the translation motor 15 rotates, the gear 17 - rack 16 mechanism drives the fixed platform 14 to move on the first slide rail 12. Furthermore, the fixed platform 14 drives the push - rod mechanism 2 to carry the guide rail to move horizontally. The overall structure is simple and the moving efficiency is improved.

[0044] Preferably, as Figures 1-3 , Figure 5 shown, the push - rod mechanism 2 includes a connecting rod 21, an adjustable block 22, and a push - rod head 24. There are two connecting rods 21 which are fixedly arranged on both sides of the fixed platform 14. The adjustable block 22 is slidably arranged on the connecting rod 21. The adjustable block 22 is fixedly connected to the connecting rod 21 through a locking bolt. The push - rod head 24 is fixedly arranged on the adjustable block 22. The two push - rod heads 24 clamp the guide rail 300.

[0045] First, place the guide rail between the two push - rod heads 24, then adjust the position of the adjustable block 22 on the connecting rod 21 to make the push - rod heads 24 clamp the guide rail. It is best to lock the adjustable block 22 on the connecting rod 21 through a bolt to fix the guide rail.

[0046] The push - rod mechanism 2 further includes a reference slider 4. The reference slider 4 is arranged on the bed surface 100, and the guide rail penetrates through the reference slider 4.

[0047] The guide rail 300 penetrates through the reference slider 4. Combining with the push - rod heads 24 on both sides of the guide rail, the guide rail is restricted both horizontally and vertically and can be stably fixed.

[0048] Furthermore, as Figures 1-3 , Figure 6 shown, the grinding mechanism further includes a servo - feed mechanism 3. The servo - feed mechanism 3 is located directly below the guide rail 300. The servo - feed mechanism 3 includes a feed motor 30, a lead - screw assembly, and a flat plate 36. A second slide rail 38 is arranged on the bed surface 100. The flat plate 36 is slidably arranged on the second slide rail 38 through a second slider 39. The reference slider 4 is fixedly arranged on the flat plate 36. The feed motor 30 is fixedly arranged on the bed surface 100. The servo - feed mechanism 3 is connected between the feed motor 30 and the flat plate 36.

[0049] The screw assembly includes a motor seat 31, a screw support seat 37, a ball screw 32 and a ball nut 33. The motor seat 31 and the screw support seat 37 are fixedly arranged on the bed surface 100. The motor seat 31 and the screw support seat 37 are located on both sides of the flat plate 36. The feed motor 30 is installed on the motor seat 31. One end of the ball screw 32 is connected to the output shaft of the feed motor 30 through a coupling 34. The other end of the ball screw 32 is rotatably connected to the screw support seat 37. The ball nut 33 is installed on the ball screw 32. The ball nut 33 is fixedly connected to the flat plate 36 through a nut seat 35.

[0050] After the push rod mechanism 2 clamps the guide rail, the propulsion mechanism 1 translates to grind the guide rail. In the initial state of grinding, the reference slider 4 is located directly below the grinding mechanism 200. When the propulsion mechanism 1 drives the end of the guide rail to move to the reference slider 4, in order to prevent the guide rail from slipping off the reference slider 4, the feed motor 30 drives the ball screw 32 to rotate, so that the ball nut 33 drives the plate 36 to move horizontally, so that the reference slider 4 on the plate 36 avoids the end of the guide rail, and then the grinding mechanism 200 can grind the end of the guide rail, and the guide rail will not detach from the reference slider 4.

[0051] Preferably, support roller frames 5 are provided on both sides of the grinding mechanism 200, and the support roller frames 5 are fixedly arranged on the bed surface 100, and the propulsion mechanism 1 can operably drive the guide rail to move on the support roller frames.

[0052] The support roller frame 5 is used to support the bottom surface of the linear guide rail when the guide rail is too long. When the guide rail moves left and right, one end is always supported on the support roller frame 5 to ensure stability when grinding the linear guide rail.

[0053] Working principle:

[0054] like Figure 7 As shown, the reference slider 4 is located directly below the grinding mechanism 200 in the initial state. Figure 7 As shown in ①, the reference slide block 4 does not move during grinding, and the guide rail is pushed to the right until Figure 7 ② When the linear guide rail end is 200 away from the grinding mechanism and the grinding wheel center length L is about to separate from the reference slider 4, the servo feed mechanism 3 drives the reference slider 4 and the linear guide rail to move to the right at the same time, passing the grinding wheel center, until the left section of the linear guide rail is completely ground. Figure 7 Then start to push the linear guide rail to the left, and at the same time, the servo feed mechanism 3 drives the reference slider 4 to move to the left and stop at the center of the grinding wheel, as shown in Figure 3. Figure 7 ④. Continue to push the linear guide to Figure 7⑥ position, at this time, a section with a length of L is also about to break away from the reference slider 4, and the operation process is the same as when grinding the left end of the linear guide rail. At this time, the grinding of the entire linear guide rail is completed, and repeating 2 - 3 times can complete the grinding of the entire linear guide rail.

[0055] The ground guide rail is as Figure 8 shown. Except for the lengths of L at both ends, the entire linear guide rail is ground above the reference slider 4 during grinding, and the reference slider 4 remains stationary, ensuring the parallelism between the two. The small sections of length L at both ends are at the two ends of the guide rail, and the slider will not move to this part during use, without affecting the overall use accuracy.

[0056] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be interpreted to include the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0057] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and its equivalent technologies, the present invention also intends to include these modifications and variations.
