Abstract
Description
Technical Field
[0001] The utility model relates to a linear guide rail assembly tooling, in particular to a linear guide rail adjusting device. Background Art
[0002] When two or more linear guide rails are installed in parallel, it is necessary to adjust the straightness of the linear guide rails, and then ensure the parallelism of the two linear guide rails, so that the moving parts can move smoothly. Especially in precision measuring equipment, the parallelism and straightness of multiple guide rails are required to be relatively high.
[0003] The existing installation methods mainly include groove positioning and pin positioning. Groove positioning is to machine a groove matching the linear guide rail on the base for fixing the linear guide rail. The accuracy requirement of this groove is relatively high, resulting in high processing cost and great processing difficulty. Pin positioning is mainly to open a plurality of pin holes on the base, and then realize the positioning of the linear guide rail through pins. However, due to machining errors and dimensional errors of the pins in pin positioning, the understanding error is relatively large. If machining errors are provided, the processing cost and detection cost are relatively high. Therefore, the effect of pin positioning is relatively poor.
[0004] Whether using groove positioning or pin positioning, when assembling the linear guide rail, it is necessary to adjust the straightness of the linear guide rail and the parallelism between the two guide rails. First, ensure the straightness of the reference guide rail. During installation, determine the positioning reference, and then gradually measure and lock the screws on the linear guide rail. This method requires repeated measurement of the straightness of the linear guide rail. Since the guide rail will also undergo slight deformation when the screws are locked, the straightness needs to be adjusted repeatedly. When installing another guide rail, the parallelism also needs to be detected. Therefore, the assembly efficiency of the linear guide rail is very low and the assembly cost is relatively high. Summary of the Utility Model
[0005] To solve the problems of relatively low assembly efficiency and relatively high assembly cost of the above-mentioned linear guide rail, the utility model provides a linear guide rail adjusting device, and the specific technical solution is as follows:
[0006] A linear guide rail adjusting device includes: positioning pins symmetrically arranged on both sides of the linear guide rail; and countersunk head screws symmetrically arranged on both sides of the linear guide rail, and the conical surface of the countersunk head screw is movably abutted against the outer circular surface of the positioning pin; wherein, the countersunk head screw pushes the positioning pin through the conical surface to adjust the linear guide rail.
[0007] Preferably, both the positioning pins and the countersunk head screws are symmetrically located on both sides of the fixing holes of the linear guide rail.
[0008] Compared with the prior art, the utility model has the following beneficial effects:
[0009] A linear guide rail adjusting device provided by the utility model adjusts the straightness and parallelism of the linear guide rail from both sides of the linear guide rail by means of countersunk head screws to extrude the positioning pins, realizes the precise positioning of the linear guide rail, can effectively avoid the linear guide rail from undergoing minute deformation when the linear guide rail is locked, eliminates the need for repeatedly adjusting the linear guide rail, greatly improves the assembly efficiency of the linear guide rail, and reduces the assembly cost.

[0015] The present utility model will be further described below in conjunction with the accompanying drawings.
[0016] As Figures 1 to 5 shown, a linear guide rail adjusting device includes a positioning pin 4 and a countersunk head screw 5. The positioning pins 4 are symmetrically located on both sides of the linear guide rail 3, and the countersunk head screws 5 are symmetrically arranged on both sides of the linear guide rail 3. Moreover, the conical surface 51 of the countersunk head screw 5 is movably abutted against the outer circular surface of the positioning pin 4, and the countersunk head screws 5 and the positioning pins 4 are in one-to-one correspondence. The countersunk head screw 5 pushes the positioning pin 4 through the conical surface 51 to adjust the linear guide rail 3. Among them, both the positioning pin 4 and the countersunk head screw 5 are symmetrically located on both sides of the fixing hole 31 of the linear guide rail 3.
[0017] When adjusting, first install the fixing screw into the fixing hole 31 of the linear guide 3, and connect it with the fixing threaded hole on the base 1, the fixing screw is in a slightly locked state, then install the fixed countersunk screw 5 into the positioning threaded hole 11, and place the positioning pin 4 between the countersunk screw 5 and the linear guide 3. When adjusting the linear guide 3, the position of the linear guide 3 is adjusted by rotating the countersunk screw 5, the conical surface 51 of the countersunk screw 5 pushes the positioning pin 4, and the positioning pin 4 pushes the linear guide 3, and the accurate positioning of the linear guide 3 is achieved by coordinating the countersunk screws 5 on both sides of the adjusting fixing hole 31, and then the fixing screws are completely locked. At this time, since both sides of the linear guide 3 are positioned, the linear guide 3 will not be slightly deformed when the fixing screws are locked, which ensures the positioning accuracy of the linear guide 3, greatly reduces the adjustment time, improves the assembly efficiency of the linear guide 3, reduces the assembly cost of the linear guide 3, and facilitates the adjustment of the linear guide 3 during later maintenance. At the same time, the structure is simple, and since standard parts are used, the cost is greatly reduced.
