Description
Technical Field
[0001] The utility model belongs to the field of guide rail grinding, in particular to a double-sided grinding clamping tool for a linear guide rail. Background Art
[0002] In the field of precision manufacturing, linear guides are key components and are widely used in various types of high-precision mechanical equipment. The accuracy, smoothness and surface quality of linear guides have a decisive influence on reducing friction and noise and ensuring the high-precision operation of equipment. Therefore, grinding is particularly important in the production and processing of linear guides.
[0003] At present, in the grinding process of linear guides, the commonly used grinding method is to clamp multiple linear guides on the workbench in sequence, and use a grinder to grind one side of the linear guide. After one side is ground, the linear guide needs to be removed from the workbench, turned over, and then re-clamped to grind the other side. This grinding method has obvious disadvantages:
[0004] 1. Low efficiency: Since the linear guide rail needs to be clamped twice, the entire grinding process takes a lot of time and manpower, resulting in low grinding efficiency.
[0005] 2. High labor intensity: During the grinding process, workers need to frequently load, unload and flip the linear guide rails, which increases the labor intensity and may also lead to errors and damage due to improper operation.
[0006] 3. Precision is difficult to guarantee: secondary clamping may cause the position of the linear guide to change, thus affecting the accuracy and consistency of grinding. Utility Model Content

[0030] A double-sided grinding clamping tool for a linear guide rail comprises a base 1 and a flip frame 2, wherein the base 1 is fixedly connected with pillars 11 at both ends, and a bearing seat 13 is provided on the pillars 11; a connecting shaft 21 is fixedly connected with each end of the flip frame 2, and the connecting shaft 21 is installed in the bearing seat 13, a motor 12 is installed on one of the pillars 11, a reducer is connected to one side of the motor 12, and the output shaft of the reducer is connected to the connecting shaft 21; a fixed plate 22 is provided at the rear end of the flip frame 2, and a movable plate 23 is provided at the front end, and a second screw 29 is threadedly connected to one end of the flip frame 2, and the second screw 29 is abutted against the movable plate 23; a clamping plate 24 is provided on the inner side of the flip frame 2, and a first screw 26 is rotatably connected to the middle part of the clamping plate 24, and the first screw 26 is threadedly connected to the left side of the flip frame 2.
[0031] Furthermore, the right inner wall of the flip frame 2 and the inner side of the clamping plate 24 are both provided with a limit strip 25, and the limit strip 25 is clamped in the guide groove 31 on the left and right sides of the linear guide 3. The inner sides of the fixed plate 22 and the movable plate 23 are both provided with a limit block 232, and the limit block 232 is clamped in the through hole formed by the guide groove 31 at the end of the linear guide 3. The limit strip 25 and the limit block 232 limit the displacement of the linear guide in the up and down directions, thereby avoiding the up and down jumping of the linear guide and ensuring the stability of the linear guide after clamping and the quality of grinding.
[0032] Furthermore, guide rods 27 are provided at both ends of the clamping plate 24, and springs 28 are sleeved on the outside of the guide rods 27. One end of the spring 28 is against the clamping plate 24, and the other end of the spring 28 is against the inner wall of the flip frame 2. The spring 28 allows the two ends of the clamping plate 24 to remain against the linear guide rail, thereby ensuring the stability of the clamping tool in clamping the linear guide rail.
[0033] Furthermore, the limit clamping strip 25 and the limit clamping block 232 are both prismatic structures with a small front end and a large rear end, and are suitable for use in clamping linear guide rails of different specifications.
[0034] Furthermore, both the fixed plate 22 and the movable plate 23 are provided with an adjustment groove 231, and one end of the limit block 232 is fixedly connected with a stud 233, the stud 233 is gap-installed in the adjustment groove 231, and a fastening nut 234 is threadedly connected to the stud 233, so as to facilitate the adjustment of the position of the limit block 232 according to the linear guide rails of different widths.
[0035] Furthermore, level bubbles 30 are provided on the upper and lower sides of the flip frame 2, which are convenient for intuitively judging the horizontality of the flip frame 2 after flipping. Support rods 14 are provided at the four corners of the base 1, and an adjusting rod 15 is provided on the support rod 14.

During this clamping process, it should be ensured that the limit clamping strip 25 is clamped in the guide groove 31 on the left and right sides of the linear guide 3; then the second screw 29 is rotated so that the movable plate 23 and the fixed plate 22 clamp the front and rear sides of the linear guide 3. During this clamping process, it should be ensured that the limit clamping block 232 is clamped in the through hole formed by the guide groove 31 at the end of the linear guide 3; the motor 12 drives the flip frame 2 to flip 90 degrees through the reducer, so that the grinding surface of the linear guide is in a horizontal position, and then the height of the corresponding position adjustment rod 15 is adjusted according to the display of the level bubble 30 to keep the flip frame 2 horizontal. After one side of the linear guide 3 is ground, the adjusting rod 15 is retracted into the supporting rod 14, and the motor 12 drives the flip frame 2 to flip 180 degrees through the reducer. After the horizontality of the flip frame 2 is adjusted again using the adjusting rod 15, the other side of the linear guide 3 is ground, reducing the number of clamping times of the linear guide 3, thereby improving the grinding efficiency and quality.
