Background
The gear grinding processing is needed in the parts of the sewing machine, and the workpiece structure is as follows: including square tip 11, the connecting portion 10 and the gerar grinding tip 8 of bending, grind the spaced tooth 7 of department on the surface of gerar grinding tip, because the shape is different at this structure both ends, and middle shape is also irregular, so adopt traditional anchor clamps to hardly press from both sides it tight, even press from both sides tightly occasionally, because the exogenic action when gerar grinding, to the different striking of work piece, in case the problem that the work piece misplaces appears, can lead to the failure of gerar grinding processing, lead to scrapping of work piece.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide the square tip that withstands the work piece through the active grab, through the grinding teeth tip's of the spacing work piece of recess lateral wall and side kicking block a sewing machine grinding teeth processing frock.
The utility model adopts the technical proposal that:
the utility model provides a sewing machine gear grinding processing frock which characterized in that: the clamp comprises a clamp seat and a quick clamp, wherein a groove is formed in the surface of the front end of the clamp seat, the surface of the left side of the groove clamps the square end of a workpiece, the surface of the right side of the groove clamps the end part of a grinding tooth of the workpiece, and the clamping part of the quick clamp arranged on the clamp seat tightly supports the workpiece in a groove.
And moreover, a vertical side top block is arranged in the clamp seat beside the groove at the end part of the grinding tooth, and the upper end of the side top block props against the surface of the rear end of the end part of the grinding tooth.
And moreover, the left surface of the groove is provided with a vertical fixed block, the right surface of the fixed block is provided with a recess, and the square end part is embedded into the recess.
Furthermore, a longitudinal adjusting screw rod is arranged on the rear end face of the clamp seat, a rotating disc is arranged at the end part of the adjusting screw rod, which is positioned on the rear end face of the clamp seat, and the end part of the adjusting screw rod, which is positioned in the clamp seat, is meshed and connected with the top block on the vertical side of the book.
Furthermore, the front end face of the clamp seat on the left side of the groove is provided with an inclined bulge, the quick clamp is fixed on the inclined plane of the inclined bulge, and the clamping part of the quick clamp is tightly pressed against the surface of the square end part and the surface of the connecting part.
The utility model has the advantages that:
the utility model discloses in, the square tip of work piece is fixed through the sunken square tip of clamping part with the active grab of fixed block, the gear grinding tip of work piece is fixed through recess right side lateral wall and side kicking block, through the connecting portion between the tight square tip in clamping part top and the gear grinding tip, from this with work piece monolithic stationary on the anchor clamps seat, because the mutually supporting of parts such as side kicking block, clamping part, even under the effect of external force when the gear grinding, also can guarantee that the work piece remains stable, machining efficiency and machining precision have been improved.
