Description
Technical Field
The invention relates to the technical field of jaw machining equipment, in particular to a lathe jaw grinding device and a machining method.
Background
The clamping jaw is a mechanical device used for clamping a workpiece on a machine tool, the workpiece is clamped by radial movement of the movable clamping jaws uniformly distributed on the chuck, a machining tool of the machine tool can machine the workpiece conveniently, and the machining precision of the clamping jaw can directly influence the stability of the clamping jaw on the workpiece, so that the machining quality of the workpiece can be influenced.
The existing jaws are usually three jaws, as shown in fig. 1, the three jaws include a step-shaped jaw body, on which a table top, a positive arc and a negative arc are arranged, the table top is three planes at the step-shaped position of the jaw body, the negative arc is a vertical surface between the table tops, and the positive arc is a vertical surface at a position opposite to the negative arc.
When carrying out adding man-hour of jack catch, the mesa to the jack catch, positive arc and anti-arc are polished, the horizontal grinder who adopts mostly goes on when polishing, the grinding machine is including feeding the bed body, it is circular to rotate on the bed body and be connected with the clamping dish, the clamping dish is, a plurality of clamping grooves have been seted up on the clamping dish, a plurality of clamping grooves are radial setting with the centre of a circle of clamping dish as the center, the one end that the centre of a circle was kept away from in every clamping groove all runs through the circumference side of clamping dish, the relative position department of clamping dish is provided with grinding machanism, grinding machanism includes the bracket, fixedly connected with has the motor of actuating lever on the bracket, fixedly connected with beats on the end of emery wheel, it sets up towards the clamping dish to polish the wheel, be provided with drive mechanism on the bed body, drive.
When polishing, firstly, a resin polishing wheel is arranged on the driving rod, then the clamping jaws are arranged in the clamping groove of the clamping plate one by one, and during clamping, the positive arc of each clamping jaw is kept to deviate from the circle center of the clamping plate. Then the motor drives the grinding wheel to rotate, meanwhile, the transmission mechanism drives the grinding wheel to be close to a single claw on the clamping disc, three claws are firstly ground, after the grinding of the single claw is finished, the clamping disc is rotated to be switched to the next claw, when the three claws on the clamping disc are completely ground, workers need to grind and process a positive arc and a reverse arc, the positive arc and the reverse arc are used as the most using positions of the claws, so that more accurate processing precision is needed, the hardness of the resin grinding wheel is difficult to meet the processing requirements of the positive arc and the reverse arc, then the grinding wheel made of white corundum materials with higher hardness and higher manufacturing cost needs to be replaced to grind and process the positive arc and the reverse arc, and the alternate use of the grinding wheel made of resin materials and the white corundum grinding wheel made of white corundum materials is the most extensive method for reducing the production cost of the claws at present.
Firstly, a polishing wheel made of resin materials used at present is detached, then the polishing wheel made of white corundum materials is replaced, then the polishing surface of the polishing wheel is repaired, after the repair is completed, the polishing wheel directly processes the reverse arcs of the clamping jaws, after the reverse arc processing is completed, the polishing wheel made of white corundum materials continuously used by workers carries out the processing of the positive arcs, before the positive arc processing is carried out, the workers need to replace the fixed positions of the clamping jaws on the clamping disc, the positive arcs of the clamping jaws are arranged towards the circle center of the clamping disc, and then the polishing wheel made of white corundum materials processes the positive arcs.
In the process of implementing the prior art, the inventor finds that the prior art has the following defects:
when the processing process of the clamping jaws is carried out, the grinding wheel needs to be replaced once, the placing mode of the clamping jaws on the clamping plate needs to be turned once, and the worker needs to carry out the adjusting process of the equipment twice in total, so that the labor steps of the worker are increased, the working duration of the worker is increased, the production efficiency of the worker is reduced, and the production rhythm of a factory is slowed down.
