先裝好直線導軌，以直線導軌的滑座為基準校正絲杠，再以絲杠兩端支承座安裝孔配作固定螺紋孔。用螺釘固定絲杠后，用磁力表座將千分表固定在直線導軌滑座上，測量絲杠、側母線和絲杠徑向跳動量，保證絲杠的平行度及跳動量在要求范圍內。

Install the linear guide rail first, calibrate the lead screw based on the sliding seat of the linear guide rail, and then match the mounting holes of the support seats at both ends of the lead screw as fixed threaded holes. After fixing the lead screw with a screw, use a magnetic meter holder to fix the dial indicator on the linear guide rail slide. Measure the radial runout of the lead screw, side bus, and lead screw to ensure that the parallelism and runout of the lead screw are within the required range.

重新配作支承座定位錐銷，裝好錐銷后再復檢一次。裝配各步驟采用的處理方法基本正確，檢測基準與工藝基準也相符，檢測量具精度也能滿足要求，被測要素也正確。整個裝配過程沒有問題，但通過在現場觀察，發現裝配工藝中仍存在以下問題:

Reassemble the bearing seat positioning taper pin, and recheck it after installing the taper pin. The processing methods used in each step of assembly are basically correct, the inspection benchmark is also consistent with the process benchmark, the accuracy of the inspection measuring tool can also meet the requirements, and the measured elements are also correct. There were no problems during the entire assembly process, but through on-site observation, it was found that the following problems still exist in the assembly process:

(1)使用手電鉆鉸孔時，由于鉸削余量較大，振動較厲害，雙手控制不穩，鉸刀擺動過大，造成錐孔鉸削后上大下小，錐度不是要求的1∶50。用涂色法進行檢查，發現錐銷與錐孔的接觸部位不正確，位置靠近小頭一端，不能保證良好的接觸精度，受到交變應力與振動時容易松動，從而導致定位精度下降。

(1) When using a hand electric drill to ream holes, due to large reaming allowance, severe vibration, unstable control of both hands, and excessive swing of the reamer, the taper of the tapered hole is not the required 1:50 after reaming. Using the color coating method for inspection, it was found that the contact position between the taper pin and the taper hole was incorrect, and the position was close to the small end, which could not ensure good contact accuracy. When subjected to alternating stress and vibration, it was easy to loosen, resulting in a decrease in positioning accuracy.

(2)機鉸后沒有留精鉸余量，也沒有進行手工精鉸。圓錐銷的配合都是依靠配合面的過盈產生摩擦力來定位的。由于機鉸后表面粗糙使實際過盈量減少，造成摩擦力不夠，自鎖性能下降，當受到交變應力與振動時容易松脫，從而導致定位精度下降。

(2) After machine reaming, there was no allowance for fine reaming, nor was manual fine reaming performed. The fitting of tapered pins is positioned by friction generated by interference on the mating surface. Due to the roughness of the surface after reaming, the actual interference amount decreases, resulting in insufficient friction, reduced self-locking performance, and easy loosening when subjected to alternating stress and vibration, resulting in reduced positioning accuracy.

(3)鉸孔時孔徑控制不嚴，鉸削過程中沒用錐銷試配，裝配時用銅棒輕輕敲入即可。由于不能保證足夠的過盈量，裝配后的摩擦力過小;受負荷及振動時易造成錐銷松動，失去定位作用，導致工作臺運動精度差。

(3) The hole diameter was not strictly controlled during reaming, and the taper pin was not used for trial fitting during the reaming process. During assembly, gently tap in with a copper rod. Due to insufficient interference, the friction force after assembly is too small; When subjected to load and vibration, it is easy to cause the taper pin to loosen and lose its positioning function, resulting in poor movement accuracy of the workbench.

(4)在鉆孔鉸孔等過程中，沒有進行防塵處理。雖然絲杠副帶有防塵圈，但鑄鐵粉塵非常細小，且易粘附在絲杠表面。如有少量進入絲杠副傳動面，粉塵的研磨作用會加劇絲杠副的磨損，導致絲杠精度下降，降低使用壽命。

(4) During the process of drilling and reaming, no dust prevention treatment was carried out. Although the lead screw pair has a dust ring, the cast iron dust is very small and easily adheres to the surface of the lead screw. If a small amount of dust enters the drive surface of the lead screw pair, the grinding effect of dust will exacerbate the wear of the lead screw pair, leading to a decline in lead screw accuracy and reduced service life.
