Description

A form grinder

technical field

The invention relates to the technical field of processing machine tools, in particular to a forming grinder.

Background technique

A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Form grinding machine is a kind of machine tool used to process the special-shaped surface of the workpiece in the grinding machine.

The current forming grinder includes a base, a workbench, a grinding mechanism, and a front and rear adjustment mechanism; the grinding mechanism includes a main shaft, a main shaft support, a grinding wheel, a first adjustment handwheel, a first screw mandrel, and a motor; the workbench is installed on On the base, the motor is fixed in the middle of the bracket, the output shaft of the motor is connected to the main shaft, the grinding wheel is installed on the main shaft, the bottom of the first screw rod is screwed with the mounting block fixed on the motor, and the first wire The top of the rod is screwed with the first adjusting handwheel. During work, the first adjustment handwheel can adjust the up and down position of the grinding wheel.

The forming grinder with the above structure has the following disadvantages: since there is only one emery wheel, it can only be ground once during processing, and the workpiece with a large allowance cannot be ground at one time, and it needs to be processed twice, so that the processing efficiency is relatively high. Low, low precision.

Contents of the invention

The technical problem to be solved by the present invention is to provide a profile grinder with high processing efficiency and high precision.

The technical solution of the present invention is to provide a form grinding machine with the following structure, including a base, a first workbench, a second workbench, a first grinding mechanism and a first front-rear position adjustment mechanism; the grinding mechanism includes a main shaft , bracket, grinding wheel, first adjusting handwheel, first screw mandrel, motor; the first workbench is installed on the base, the motor is fixed in the middle of the bracket, the output shaft of the motor is connected with the main shaft, and the The grinding wheel is installed on the main shaft, the bottom of the first screw rod is screwed with the mounting block fixed on the motor, and the top of the first screw rod is screwed with the first adjusting hand wheel; it is characterized in that it also includes another A set of matching second grinding mechanism and second front and rear position adjustment mechanism, the second grinding mechanism is slidingly fitted on the base, the first and second grinding mechanisms are arranged side by side laterally, the first and second The axes of the main shafts of the two grinding mechanisms are parallel, and the second workbench is also provided with a feeding device.

After adopting the above structure, compared with the prior art, the present invention has the following advantages: because a new group of matching grinding mechanism and front and rear position adjustment mechanism are newly added, that is to say, there are two grinding wheels, and the two grinding wheels can be adjusted separately. The workpiece can be roughly ground and finely ground, and the workpiece with a large allowance can be ground in place at one time without having to process it twice, so that the processing efficiency and precision are high. Since the workbench is also provided with a feeding device, the material can be automatically fed to the clamps on the workbench during processing, thereby improving work efficiency.

As an improvement, the front and rear position adjustment mechanisms all include a mounting block fixed at the bottom of the bracket, a second hand wheel and a second lead screw, the second lead screw is screwed into the threaded hole on the mounting block, and the second hand wheel The wheel is set at the outer end of the second lead screw. Since the grinding mechanism can be adjusted forward and backward through their respective front and rear position adjustment mechanisms, that is, without moving the worktable, two sets of grinding mechanisms can be moved respectively, so that the two grinding wheels can be guaranteed in a straight line.

As an improvement, the sliding fit between the brackets of the two sets of grinding mechanisms and the base means that the base is provided with four T-shaped guide rails, and the bottom of the bracket is provided with T-shaped grooves for sliding fit of the corresponding T-shaped guide rails. , through the sliding connection between the bracket and the guide rail on the base, so that the movement accuracy of the bracket is high, and the processing accuracy of the product is improved.

As an improvement, the feeding device includes a housing that can be arranged on the second workbench, a first feeding roller and a second feeding roller that protrude from the housing and rotate in opposite directions, a first rotating shaft arranged in the housing, a second Two rotating shafts, a third lead screw, a fourth lead screw, a first adjustment handle and a second adjustment handle; the first feeding roller is connected to the first rotating shaft, the second feeding roller is connected to the second rotating shaft, and the first feeding roller is connected to the second rotating shaft. The bottom end of the three leading screws is connected with the first rotating shaft, the top end of the third leading screw is connected with the first adjusting handle, the top end of the fourth leading screw is connected with the second rotating shaft, and the bottom end of the fourth leading screw Connect with the second adjustment handle. The first adjustment handle and the second adjustment handle with the above structure can adjust the first feeding roller and the second feeding roller respectively, and the adjustment is convenient.
