Description

Thin slice part grinding tool

Technical Field

The utility model relates to an auxiliary fixtures that thin slice parts machining used, concretely relates to thin slice parts grinding frock.

Background

The friction plate, sample plate, thin plate and other sheet parts commonly used in machining are poor in rigidity, difficult to dissipate heat, bent after heat treatment, easy to warp during clamping and grinding, and are usually ground and machined on a surface grinding machine by adopting a magnetic chuck.

As shown in fig. 1, an elastic pad 300 is disposed between an electromagnetic disk 100 and a thin sheet member 200. When the thin sheet part 200 is tightly sucked, the elastic pad 300 is compressed to support the thin sheet part 200 to a certain extent, so that elastic deformation can be reduced when the thin sheet part 200 is ground. However, since the electromagnetic disk 100 has an adsorption force, the ground thin sheet part 200 still has a certain elastic deformation after grinding, and the thin sheet part 200 is in complete sealing contact with the elastic gasket 300, so that heat dissipation is difficult during grinding, and warping of the thin sheet part 200 may be caused during grinding.

The scheme of the elastic gasket 300 has limited effect, cannot completely meet the grinding requirement, needs to repeatedly turn over and grind two surfaces on the basis of the elastic gasket 300 to ensure the processing precision, and has low processing efficiency and high working strength, thus being not suitable for processing workpieces in large batches.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the problem of radiating difficulty in the thin slice part grinding process, provide a thin slice part grinding frock.

In order to achieve the above object, the present invention provides the following technical solutions:

the utility model provides a thin slice part grinding frock, includes the base, the base is the ascending spill container of opening, be arranged with the bulb support column in the base in the matrix, be equipped with the spring between support column and the spill container bottom, the end is used for contacting the thin slice part.

When the thin sheet part grinding tool is applied, the thin sheet part grinding tool is arranged on a magnetic workbench of a grinding machine, and when the thin sheet part is placed on the tool in the scheme under the magnetic adsorption state of the workbench, the end of the support column can be matched with the shape of the lower surface of the thin sheet part under the action of the spring, so that the thin sheet part and the tool form a whole.

After the thin sheet part is installed, the lower surface of the thin sheet part is in point contact with the upper hemispherical end of the support column, and an air circulation or cooling liquid storage space is formed between the ends of the plurality of support columns on the lower surface of the thin sheet part, so that heat dissipation of the processed part is facilitated.

In the process of grinding the thin sheet part, the spring below the supporting column enables the end head on the supporting column and the thin sheet part to be always kept in a tightly-pressed state, and cooling liquid of the grinding machine can flow through the gaps, so that the thin sheet part can be sufficiently cooled through the cooling liquid in the grinding process.

Furthermore, the lateral wall of base exceeds the support column, and the department of the portion of exceeding is equipped with first screw, and the overlap joint has first screw in the first screw.

When the thin sheet part is placed on the thin sheet part grinding tool, a first screw is additionally arranged through a first screw hole, and the thin sheet part is limited from the side surface. In the process of grinding the thin sheet part, the friction force generated by the grinding wheel has the tendency of pushing the part to move forwards, and the first screw arranged in the side direction of the thin sheet part can prevent the thin sheet part from sliding, so that the processing safety is ensured.

Furthermore, the supporting column is of a circular columnar structure, and a spring hole for installing the spring is formed in the supporting column; the support columns are paved on the inner bottom surface of the base. The characteristic that only line contact is formed among the closely distributed circular columns is utilized, the whole heat dissipation area is increased, and the heat dissipation effect is improved; simultaneously, the spring is installed through the spring hole of support column, can effectively reduce overall height, improves stability.

Furthermore, an annular groove is formed in the inner wall of the base, and a C-shaped ring is arranged in the annular groove; a second screw hole is formed in the side wall of the base at the position opposite to the C-shaped ring, a second screw is matched in the second screw hole, and the second screw is abutted to the C-shaped ring; all of the support posts are located within the C-ring.

And adjusting a second screw abutted to the C-shaped ring, and contracting the second screw to enable the C-shaped ring to tightly hold the plurality of supporting columns so as to form a whole.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the support column upper end in this scheme forms the gap of a plurality of intercommunications with the thin slice part, and at grinding thin slice part in-process, the spring under the support column makes end and the thin slice part on the support column remain the tight state in top all the time, and the coolant liquid alright of grinding machine circulate in following these gaps for the thin slice part can fully dispel the heat at the in-process of grinding.

2. The first screw is arranged in the side direction of the thin sheet part to block the thin sheet part, so that the position of the thin sheet part is unchanged in the whole grinding process, and the state is stable. The support column can be held tightly to the C shape ring of second screw cooperation, for the thin slice part provides good grinding environment in grinding process, improves production efficiency and product quality.
