Description

Vertical machining center main box fixed scraping and grinding bracket

technical field

The utility model belongs to the technical field of assembly of the spindle box sequence of a numerically controlled vertical machining center, in particular to a fixed scraping and grinding support for the main box of a vertical machining center.

Background technique

The assembly of the spindle box sequence of the vertical machining center requires turning the spindle box over, scraping the spindle mounting surface, and installing the spindle into the spindle mounting hole. At the assembly site, the headstock is often put down by placing wood or rubber under the headstock. In this way, there is a risk of damage to the punching cylinder seat protruding from the headstock when it falls to the ground. There have also been cases where the collision between the punching cylinder seat and the ground caused the headstock to be scrapped. In addition, due to the limitation of the shape and structure of the spindle box, the spindle mounting hole is not vertically upward when the spindle box is put down, which causes a certain inconvenience for the operator to scrape and grind the spindle mounting surface. When the spindle is installed into the spindle hole in an inclined direction, the assembly process is not smooth. It is necessary to tap the spindle with tools such as a leather hammer to make it smoothly installed into the spindle box.

Utility model content

In order to solve the above technical problems, a fixed scraping and grinding bracket for the main box of a vertical machining center is provided, which solves the problems that the main sequence assembly process of the vertical machining center is not smooth and there are certain hidden quality risks.

In order to achieve the above purpose, the technical scheme of the present invention is as follows: a vertical machining center main box fixed scraping and grinding support, the spindle box scraping and grinding support includes a front support and a rear support, and the height of the front support is less than the height of the rear support.

The headstock scraping and grinding frame is provided with a pressure plate, and the pressure plate is connected with the headstock through a coupling structure to limit the position of the headstock.

The upper end surfaces of the front support and the rear support are provided with rubber skins.

A limit structure is welded on one side of the front support, and the limit structure is located on the side opposite to the direction of the front support and the rear support.

The limiting structure is an L-shaped side baffle.

The coupling structure includes a screw rod and a nut, the screw rod penetrates the pressing plate, and the nut is screwed on the screw rod.

The beneficial effects of the present utility model are:

To solve the problem that the main sequence assembly process of the vertical machining center is not smooth and there are certain hidden dangers in quality, the headstock can be balanced on the ground by scraping the headstock and fixed with a pressure plate.

The front support and rear support are designed with steps, which can effectively protect the cutter cylinder seat, and at the same time, the spindle installation surface can be in a horizontal position, which is convenient for the operator to scrape and grind. When installing the spindle, it can ensure that the spindle falls into the spindle installation hole in a vertical direction. Inside.

The main body is welded with square steel pipes, with simple structure, convenient manufacture, low cost, and easy to popularize in the production workshop of machine tools;

The utility model fully considers the convenience and safety of the operator when using it, which can improve production efficiency and eliminate potential safety hazards;

The utility model protects the vulnerable positions of the parts, and can effectively reduce the failure rate.

Detailed ways

As shown in Figures 1-5, a vertical machining center main box has a fixed scraping and grinding bracket. The scraping and grinding bracket 1 of the spindle box is provided with a pressure plate 4. position is limited.

The headstock scraping and grinding frame 1 includes a front support 14 and a rear support 15. The height of the front support 14 is less than the height of the rear support 15. The upper end surfaces of the two are provided with rubber sheets 5, which play the role of shock absorption and anti-friction, and are compatible with the headstock. 7 will not cause damage to the surface of the headstock 7 when contacted.

An L-shaped side baffle 9 is welded on one side of the front support 14. When the spindle box 7 is placed on the spindle box scraping and grinding frame 1, the position of the spindle box 7 is limited, which solves the problem of the spindle box 7 caused by the inaccurate position of the spindle box. The problem of damage caused by the contact between the knife cylinder seat 8 on the 7 and the ground.

The coupling structure includes a screw 3 and a nut 2. After the spindle box 7 is placed on the spindle box scraping and grinding frame 1, the pressure plate 4 is placed on the spindle box 7, and the nuts 2 on the screw 3 on both sides are tightened to fix the spindle box 7 on the spindle. On the box scraping and grinding frame 1, the spindle mounting surface of the spindle box 7 can be scraped and ground at this time.

The working principle of the utility model is:

The front support 14 and the rear support 15 of the headstock scraping and grinding frame 1 adopt a stepped structure and are glued with rubber 5; when the headstock 7 is lifted by the cloth rope 6 and falls on the headstock scraping and grinding frame 1, it is blocked by the side plate 9 for positioning; when the spindle box 7 falls stably, the knife cylinder seat 8 can be protected to prevent it from being damaged due to contact with the ground; place the pressure plate 4 on the spindle box 7, and tighten the nuts 2 on both sides of the screws 3 , fix the spindle box 7 on the spindle box scraping and grinding frame 1, at this time, the spindle mounting surface of the spindle box 7 can be scraped and ground; 10 falls into the spindle mounting hole 13 of the spindle box 7 in a vertical direction to complete the assembly.

The utility model can protect the protruding cutter cylinder seat on the spindle box, and the spindle box is fixed by the pressure plate, which can ensure the safety of the operator in the process of scraping and grinding and the installation process of the spindle, and the utility model fully considers the spindle box. The shape and structure of the spindle box can be in the same line as the direction in which the spindle falls, so that the spindle can be installed smoothly.
