Description

Fixtures for auxiliary machining of oblique holes in square tool holders

technical field

The utility model relates to a clamp, in particular to a clamp used for auxiliary processing of inclined holes of a square tool holder.

Background technique

At present, the clamping effect of the traditional square turret oblique hole fixture is poor, so that the workpiece is affected by the cutting force and inertial force during the processing and changes the original position of the workpiece, thereby affecting the machining accuracy of the workpiece. The finished product rate of the workpiece will be affected, and it needs to be repaired later, which will increase the work intensity of the technicians and affect the production progress. At the same time, some workpieces will be scrapped due to the failure of the repair, which will affect the efficiency of the enterprise.

Utility model content

The utility model aims to solve the above-mentioned shortcomings of the prior art, and provides a fixture with reasonable structure and convenient use for assisting in the processing of inclined holes of square tool holders, which ensures the stability of the clamping, ensures the processing accuracy, improves the yield, and is convenient and fast.

The technical solution adopted by the utility model to solve the technical problem: the clamp used for auxiliary processing of the inclined hole of the square tool holder includes a clamp body, the clamp body is provided with a positioning bolt for clamping the workpiece, and the front end of the positioning bolt is provided with a clamp The clamping nut for tightening the workpiece is screwed on the positioning bolt; the top of the clamping body is provided with a shaft seat, the shaft seat is rotatably connected with a drill template, and a drill sleeve is inserted in the drill template. In this way, the positioning bolt is used to install the workpiece, and the clamping nut is used to fix the workpiece, so that the performance is stable during processing. In order to prevent the drill bit from deflecting when drilling inclined holes, the drill sleeve is used and made into a quick change form to complete the processing content of drilling, expanding and reaming. At the same time, the drilling template can be turned over, and the drilling template is used to limit the position of the workpiece to further ensure stability. Sex, making the processing effect better.

For further improvement, there is a notch at the upper end of the drill sleeve; a threaded hole is opened on the drill template, and a set screw is screwed in the threaded hole, and the upper part of the set screw is stuck in the notch. In this way, the position of the drill sleeve is fixed by the set screw, so that the drill sleeve is not affected by the stress generated during processing. While ensuring the processing accuracy, it can also protect the drill bit, prevent the drill bit from being damaged, extend the service life, and reduce the cost.

As a further improvement, a washer is provided outside the positioning bolt. In this way, the washer serves to protect the surface of the workpiece being scratched by the clamping nut and to distribute the pressure of the clamping nut on the workpiece.

As a further improvement, slots are provided on the washer, and the washer is inserted outside the set bolt through the slot. In this way, the setting of the slot facilitates the quick installation of the washer on the positioning bolt, which breaks away from the traditional installation method of inserting through a round hole and speeds up the installation efficiency.

For further improvement, a positioning block is installed on the clamp body. In this way, the setting of the positioning block facilitates the rapid installation of the workpiece, ensures the accuracy of the installation position, improves efficiency, saves time, and at the same time ensures the processing quality without processing deviation.

Further improvement, the upper end surface of the positioning block and the center line of the positioning bolt are set at 60°. In this way, there is a deviation in the angle between the outer end face and the end face of each workpiece, generally 60° is the standard angle, and the positioning block can also be adjusted according to the measured angle, so that the end face and the upper end face of the positioning block are closely attached combine.

The beneficial effects of the utility model are: the utility model has a simple structure and is easy to operate. It is used for special fixed drilling molds and for processing inclined holes of lathe tool holders, which reduces costs, improves production efficiency, and expands the usability of lathes. It is worth popularizing .
