Description

An elastic head mechanism for switching between grinding and polishing

technical field

The utility model relates to the technical field of grinding and polishing, in particular to an elastic head mechanism for switching between grinding and polishing.

Background technique

With the expansion of the application range of ultra-precision machining and the continuous improvement of its application precision, higher requirements are put forward for the instruments and means of ultra-precision machining. As a means of final processing, ultra-precision machining technology has attracted more and more attention from the scientific research circles around the world. Therefore, it is necessary to master the material removal mechanism in the ultra-precision machining process and develop a series of experimental devices for this aspect of processing on this basis. appears to be particularly important.

In ultra-precision machining equipment, it is necessary to frequently switch the tightness of the clamping device to adjust the different processing states of the workpiece, which is convenient for the experimenter to record the experimental data. In traditional processing devices, the elastic device is often composed of many complicated mechanisms or parts. To complete a clamping or loosening action of the clamping device, it takes a lot of time for the experimenter to perform a series of tedious operations. Like this, not only wasted the precious time of the experimenter, but also increased the possibility that the experiment process takes place dangerous.

Therefore, it is particularly important to design an elastic head mechanism for switching between grinding and polishing that is convenient to adjust, saves time and is safe to operate.

Utility model content

The purpose of this utility model is to solve the deficiencies of the prior art, and propose an elastic head mechanism for switching between grinding and polishing, which is installed at the clamping device of the ultra-precision processing device, which is convenient to adjust, easy to operate, labor-saving, labor-saving, and safe. high sex.

The utility model achieves the above object through the following technical solutions: an elastic head mechanism for switching between grinding and polishing, including a spherical connection seat, a ball seat, a fixing screw and a polishing disc, the bottom of the ball seat is fixedly connected with the polishing disc, and the ball seat The top of the ball seat is provided with a groove matching the bottom of the ball seat, and the ball seat is set in the groove on the top of the ball seat and can slide up and down along the groove; the surface of the ball seat is along the circumference There are a plurality of key grooves in the direction, and the ball seat is provided with threaded holes corresponding to the positions of the above-mentioned multiple key grooves one by one for the fixing screws along the circumferential direction; when the fixing screws are not tightened, the spherical connecting seat and the spherical seat are in the In the state of relative movement, the height of the polishing disc fixedly connected with the ball seat can be adjusted by sliding the spherical connection seat up and down in the groove on the top of the ball seat; The fixing screw is tightened until the fixing screw tightens the groove, so that the spherical connection seat and the ball seat are in a state of being incapable of relative movement.

Further, there are four keyways on the spherical connecting seat and four threaded holes on the ball seat.

Further, the width of the keyway on the spherical connection seat is the same as the diameter of the threaded hole on the ball seat.

Further, the polishing disc is fixed on the bottom of the ball seat by bolts.

The beneficial effect of the utility model is that: compared with the previous designs, the utility model has the characteristics of resource saving, cost saving, simple operation, safer and more efficient; when the processing device needs to adjust the tightness of the workpiece, the experimenter only needs to It is necessary to adjust the tightness of the fixing screw to easily achieve the purpose of controlling the tightness of the fixture. Use a screwdriver to tighten the fixing screw to the top tight keyway, and the device will reach the clamping state; otherwise, the device will be in the loosening state.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 1 to 4, an elastic head mechanism for grinding and polishing switching includes a spherical connection seat 1, a ball seat 2, a fixing screw 4 and a polishing disc 5, the bottom of the ball seat 2 is fixedly connected to the polishing disc 5, The polishing disc 5 is fixed on the bottom of the ball seat 2 by bolts. The top of the spherical connection seat 1 is connected to a driving device that drives the polishing disc 5 to rotate.

The top of the ball seat 2 is provided with a groove that matches the bottom of the ball seat 1, and the ball seat 1 is set in the groove on the top of the ball seat 2 and can slide up and down along the groove; The surface of the connecting seat 1 is provided with four keyways 3 along the circumferential direction, and the spherical seat 2 is provided with threaded holes corresponding to the positions of the above four keyways 3 along the circumferential direction for the fixing screws 4 to match. The width of the keyway 3 on the connecting seat 1 is the same as the diameter of the threaded hole on the ball seat 2 .

When the fixing screw 4 is not tightened, the spherical connection seat 1 and the spherical body seat 2 are in a relatively movable state, and the spherical connection seat 1 slides up and down in the groove at the top of the spherical body seat 2 to adjust the position of the polishing disc 5 fixedly connected to the spherical body seat 2. Height; when the fixing screw 4 is tightened, the keyway 3 and the threaded hole are in one-to-one alignment state, and the fixing screw 4 is manually tightened until the fixing screw 4 is tight against the groove, so that the spherical connection seat 1 and the ball seat 2 cannot move relative to each other state.

The above-described embodiments are only preferred embodiments of the present utility model, and are not limitations to the technical solutions of the present utility model. As long as the technical solutions that can be realized on the basis of the above-mentioned embodiments without creative work, all should be regarded as falling into the scope of this invention. within the protection scope of utility model patents.
