Abstract

A grinding tool of a sheet part comprises a grinding base (1) and is characterized in that at least two rows of concave blind holes (2) are formed in the upper portion of the grinding base (1), the number of the blind holes (2) in each row is at least two, and the blind holes (2) are matched with the sheet part to be machined so that the sheet part to be machined can be horizontally placed on bottom planes in the concave blind holes (2), and the depth of each blind hole (2) is smaller than the thickness of the sheet part to be machined. The grinding tool has the advantages of being simple, high in machining efficiency and suitable for large-scale production.

Description

The sheet parts grinding fixture

Technical field

The utility model relates to the work support that is applicable to grinding machine or device usually, is related to the microstoning surface of the work and the device for machine tool that designs, refers to a kind of sheet parts grinding fixture especially.

Background technology

In some electric equipment products such as contact-making switch and temperature detector, use a lot of sheet parts, the some of them sheet parts has very high surface roughness and flatness requirement, generally need carry out grinding with surface grinding machine, but surface grinding machine generally all is to come the clamping sheet parts to process by magnetic force, and can't adopt existing surface grinding machine to come its thickness is processed for the nonmagnetic sheet parts that adopts non-magnetic material to make, in the prior art, thickness processing for nonmagnetic sheet parts, often to adopt the fixing method of screw, this method not only exists the low shortcoming of working (machining) efficiency, but also exists the crudy instability, problems such as frock complexity.Therefore, the mode of the nonmagnetic sheet parts thickness of existing processing can not satisfy the requirement of production.

Summary of the invention

At the shortcoming of prior art, the purpose of this utility model is to provide the sheet parts that a kind of frock is simple, working (machining) efficiency is high, be suitable for producing in batches grinding fixture.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of sheet parts grinding fixture is provided, include and grind seat, it is characterized in that: above the grinding seat, be provided with at least two row's spill blind holes, the blind hole number that every row's blind hole comprises is two at least, described blind hole and processed sheet parts match, make processed sheet parts can lie on the baseplane in the spill blind hole and the degree of depth of blind hole less than the thickness of processed sheet parts.The utility model arranges a considerable amount of sheet parts above the seat and places blind holes grinding, and the sheet parts of some is put into ground seat, and the circumferential wall of blind hole can effectively limit the movement of sheet parts, need not fixingly can carry out attrition process especially.

Emery wheel was unlikely to be ground to and grinds seat when the degree of depth of blind hole can make processing less than the thickness of processed sheet parts.

Further, some abaculus can be arranged, have some through holes, this abaculus to be embedded on the described abaculus and grind on the seat, the through hole on the abaculus forms blind hole at the grinding seat.

The beneficial effects of the utility model are: frock is simple, working (machining) efficiency is high, be suitable for batch process.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the second example structure schematic diagram of the present utility model.

Fig. 4 is the B-B cutaway view of Fig. 3.

Among the figure: 1 is that grinding seat, 2 is that blind hole, 3 is abaculus.

The specific embodiment

Referring to accompanying drawing, a kind of sheet parts grinding fixture of the utility model, include and grind seat 1, it is characterized in that: above grinding seat 1, be provided with at least two row's spill blind holes 2, the blind hole number that every row's blind hole 2 comprises is two at least, described blind hole 2 matches with processed sheet parts, make processed sheet parts can lie on the baseplane in the spill blind hole 2 and the degree of depth of blind hole 2 less than the thickness of processed sheet parts.

In embodiment of the present utility model, include some abaculus 3, on the described abaculus 3 some through holes are arranged, this abaculus is embedded in and grinds on the seat 1, and the through hole on the abaculus 3 is grinding seat 1 formation blind hole 2.

Claims

1. sheet parts grinding fixture, include and grind seat (1), it is characterized in that: be provided with at least two row's spill blind holes (2) in the top of grinding seat (1), the blind hole number that every row's blind hole (2) comprises is two at least, described blind hole (2) matches with processed sheet parts, make processed sheet parts can lie on the baseplane in the spill blind hole (2) and the degree of depth of blind hole (2) less than the thickness of processed sheet parts.

2. sheet parts grinding fixture according to claim 1, it is characterized in that: also include some abaculus (3), described abaculus has some through holes on (3), and this abaculus is embedded in and grinds on the seat (1), and the through hole on the abaculus (3) is grinding seat (1) formation blind hole (2).
