Technical Field

The invention relates to the field of grinding equipment, in particular to a double-floating grinding head and a clamping device.

Background

The lamp holder is a connector which is connected with the tail end of a lamp wire and used for installing a bulb, and is a connecting part of a light source and an external power supply, and the light source is connected with electricity through the lamp holder to generate a light-emitting phenomenon. Can be divided into plastic cement electric wooden lamp holder, ceramic lamp holder, metal lamp holder and wooden lamp holder according to the material. Among them, the ceramic base is a commonly used one. Referring to fig. 1, in the process of manufacturing the ceramic lamp holder S1, the surface of the rolled blank needs to be polished and trimmed to be smooth, which is called a trimming process in the manufacturing process. Referring to fig. 2, most of the traditional fettling procedures adopt manual fettling, and a few of the traditional fettling procedures use a motor to drive a traditional grinding head S2 to rotate and fettle. Because the ceramic lamp holder S1 is made of ceramic, the ceramic lamp holder is hard in characteristic but also brittle, when the ceramic lamp holder S1 is ground by using the motor to drive the traditional grinding head S2, the traditional grinding head S2 is in rigid contact with the ceramic lamp holder S1, and no radial and axial avoiding space exists, so that the ceramic lamp holder S1 is easily damaged and broken, and the ceramic lamp holder S1 is rarely used and mostly subjected to manual blank grinding.

Disclosure of Invention

The invention provides a double-floating grinding head, which solves the defects that the traditional grinding head used in the prior ceramic lamp holder blank-trimming procedure is in rigid contact when the ceramic lamp holder is trimmed, has no radial and axial avoiding space and is easy to damage the ceramic lamp holder.

The technical scheme of the invention is realized as follows:

a double-floating grinding head comprises a hollow grinding head pipe body, wherein at least two axial floating clamping grooves are formed in the side wall of an upper pipe part of the grinding head pipe body, the axial floating clamping grooves are used for being connected with a clamping device, and the clamping device is connected in the axial floating clamping grooves and can float along the axial direction of the grinding head pipe body; at least two grooves are uniformly formed in the side wall of the lower pipe portion of the grinding head pipe body along the axial direction, the grooves are communicated to the lower end face of the grinding head pipe body, the grooves are used for separating the lower portion of the grinding head pipe body into at least two grinding discs, and the grinding discs can elastically swing along the radial direction.

Wherein, the thickness of the upper pipe part of the grinding head pipe body and the grinding disc is 1 mm.

Wherein, the material of bistrique body is spring steel.

The axial floating clamping groove is a rectangular groove.

The side wall of the upper pipe part of the grinding head pipe body is also provided with an inlet groove, one end of the inlet groove is communicated with the upper end face of the grinding head pipe body, the other end of the inlet groove is communicated with the axial floating clamping groove, and the inlet groove and the axial floating clamping groove are arranged in an L shape.

In addition, the invention also provides a clamping device which is used for matching with the axial floating clamping groove of any one of claims 1 to 4 and comprises a clamping joint, wherein the clamping joint is provided with a transverse spring hole, a spring is sleeved in the spring hole, the outer end of the spring is contacted with a clamping column, the side surface of the clamping column is provided with an axial limiting sliding groove, the clamping joint is connected with a jackscrew or a bolt matched with the limiting sliding groove, the clamping joint is used for being sleeved in the grinding head pipe body, and the clamping column is used for being clamped into the axial floating clamping groove.

And the inner end surface of the clamping column is provided with a spring positioning groove matched with the spring.

The clamping head is characterized in that a shaft connecting hole is formed in the upper end face of the clamping head, and a fixing bolt communicated with the shaft connecting hole is arranged on the side face of the clamping head.

The invention has the beneficial effects that: the grinding head pipe body can float up and down along the axial direction, the grinding disc can float left and right along the radial direction, floating avoiding spaces are provided on the axial direction and the radial direction when the ceramic lamp holder is ground, and the grinding disc can be prevented from damaging the ceramic lamp holder; the clamping device can be well matched with the axial floating clamping groove, and the clamping is simple and convenient.
