When the precision is adjusted correctly, glue is filled between the upright post and the plane of the glue-filling high-block tool, the upright post is installed after the glue-filling high-block tool is removed, and the precision is still unchanged.

In order to achieve the above purpose, the technical scheme of the utility model is as follows: a glue pouring tool for a slide block attaching surface of a linear guide rail is characterized in that glue pouring high blocks are fixed on a guide rail slide block through a plurality of glue pouring high blocks fastening screws, sealing rubber rings are arranged at bosses of the glue pouring high blocks fastening screws, stand columns are arranged above the glue pouring high blocks, glue pouring high blocks and the stand columns form glue pouring spaces, the stand columns are connected with the guide rail slide block through fixing screws, the sealing rubber rings are arranged at the bottoms of the fixing screws, and glue pouring openings are formed in the stand columns.

Preferably, the glue pouring tool for the bonding surface of the slider of the linear guide rail is characterized in that the upper and lower adjusting screws penetrate through the vertical column downwards along the Z-axis direction to be in contact with the glue pouring high blocks, and the front and rear adjusting screws penetrate through the vertical column along the Y-axis direction to be in contact with the glue pouring high blocks.

Preferably, foretell linear guide's slider binding face department encapsulating frock, its characterized in that, the encapsulating space is equipped with joint strip all around.

Preferably, foretell linear guide's slider binding face department encapsulating frock, its characterized in that is equipped with the exhaust hole that communicates with the encapsulating space on the stand.

The utility model has the advantages that:

1. the utility model provides a difference of the difference in height of the front and back guide rail of lathe bed and the frock of scraping leads to the internal stress that the faying face of the stand after the scraping produced with the slider. The actual height difference of the bed guide rail is utilized for glue pouring, so that the height difference of the front and rear sliding block joint surfaces of the upright post is completely consistent with the height difference of the front and rear surfaces of the bed guide rail. And ensuring that the guide rail sliding block has no internal stress after being assembled.

2. The utility model discloses avoided the stand to scrape and need to exceed the difficult technology of operation that 1.5 meters's stand overturns repeatedly. The efficiency is improved by more than 50%.

3. The utility model is suitable for a connect after the alignment relative relationship between each large-scale part of lathe through the encapsulating mode. The machining precision and the machining difficulty of parts are reduced, the precision zero-approaching is realized through fine adjustment, and the precision of the machine tool is effectively improved.

4. The utility model discloses optimized horizontal machining center's parts machining structure, improved the installation and the precision adjustment method of stand, improved the assembly precision of lathe more than 20%, assembly efficiency has improved more than 50%. The capacity requirement of at least 50 horizontal machining centers every year is ensured, and a feasible technical scheme is provided for three-year planning of more than 200 annual production centers. This frock greatly reduced the intensity of labour of artifical scraping, reduced the safety risk that the stand upset brought simultaneously, more improved the product precision through technological innovation, promoted company's product competitiveness, the high-quality development of helping hand enterprise.
