Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation. A secondary grouting method for machine tool installation, which is carried out according to the following steps:

[0021] 1) Preparation

[0022] ①Three days before the second grouting, fill the foundation hole where the anchor bolts (5) are placed with water, and pump out the water on the day of the second grouting;

[0023] ②Adjust the adjustable shim (2) to the middle position through the adjusting bolt;

[0024] ③ Screw the nut (4) to the appropriate position of the anchor bolt (5), and ensure that the nut (1) has 7-15mm adjustment space;

[0025] 2) Secondary grouting

[0026] ① Lift the base of the machine tool, such as figure 1 Install the anchor bolts (5) as shown, and fix the anchor bolts (5), adjustable pad iron (2) and backing plate (3) on the machine tool base with nuts (1) and nuts (4), as shown in figure 2 As sho...

Abstract

The invention relates to a mother machine installation secondary grouting working method. The mother machine installation secondary grouting working method is performed according to the procedures: firstly, the preparation work for the secondary grouting, the base body of the mother machine is hanged up, the anchorage bolts are installed, the anchorage bolts, the adjustable iron pads and the backing plates are fixed on the base body of the mother machine through nuts, part of the adjustable iron pads and backing plates are positioned beside the foundation holes for supporting, and the foundation parts are hanged onto the supporting iron pads; secondly, the mother machine is roughly adjusted with a level meter; thirdly, the foundation secondary grouting is performed until the no hollow cavity or concave pit is found under the backing plate; fourthly, foundation maintenance is performed. Through the connection of the adjustable iron pads, the anchorage bolts and the backing plates with the foundation of the mother machine before the grouting in the invention, the secondary grouting is performed, to cause the foundation to be completely contacted with the adjustable iron pads, the foundation quality is guaranteed, the backing plates are grouted together with the foundation after the secondary grouting, and if the adjustable iron pad is damaged, the adjustable iron pad can be replaced arbitrarily, and the contacting effect of the adjustable iron pads with the foundation is not influenced.

Description

technical field [0001] The invention relates to a secondary grouting method for installing industrial equipment, in particular to a secondary grouting method for machine tool installation, which is used for the grouting process of foundations at anchor bolts when heavy machine tools are installed on formal foundations. Background technique [0002] In the past, when heavy-duty machine tools were installed on formal foundations, the anchor bolts were hung on the base of the machine tool, and then the base of the machine tool was placed on the base. Secondary grouting, wait until the cement in the anchor bolt hole is filled until it is flush with the ground. After the cement maintenance is completed, insert the adjustable pad iron at the anchor bolt. The foundation completed by this construction technology, due to the poor flatness of the cement foundation itself, cannot completely contact the foundation and the adjustable shim, and there is no surface contact between the fou...
