Rotary table tool clamp

Abstract

The invention relates to the technical field of rotary table clamps, in particular to a rotary table tool clamp. The clamp comprises a device body, the device body comprises a rotary table body, a transmission shaft is installed at one end of the rotary table body, and the outer side of the transmission shaft is sleeved with a main bevel gear through a bearing. Through the arrangement of the transmission shaft, the main bevel gear, auxiliary bevel gears, threaded rods, movable lantern rings and chucks, the four auxiliary bevel gears are driven to rotate when the main bevel gear rotates, so that the four threaded rods can rotate at the same time, namely, the four chucks are driven to clamp a machined workpiece at the same time; and in addition, due to the fact that the four chucks move at the same time, it can be guaranteed that the four chucks can make contact with the workpiece at the same time, the situation that the workpiece generates a certain displacement stroke due to the fact that a single chuck makes contact with the workpiece is avoided, therefore the situation that the initial machining center of the workpiece is changed in the clamping process is avoided, and the workpiece machining quality of the device is guaranteed to a certain extent.

Description

technical field [0001] The invention relates to the technical field of turntable fixtures, in particular to turntable tooling fixtures. Background technique [0002] Fixture refers to the device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position to accept construction or inspection, also known as fixture. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. The fixture usually consists of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, a tool setting guide element (to determine the relative position of the tool and the workpiece or to guide the direction of the tool), and an indexing device (to enable the workpiece to be positioned in one installation. Complete the processing of several stations, there are two types of rotary indexing device and linear m...

Problems solved by technology

[0004] The object of the present invention is to provide a tooling fixture for a turntable to solve the above-mentioned background technology. The current clamping method that the turntable uses more often is to clamp with four claws and multiple claws. This clamping method can increase the force points of the workpiece. Reduce the probability of the workpiece being displaced by vibration during processing. At the same time, the clamping of multiple jaws is generally carried out sequentially, so that when this clamping method is advanced and fixed in sequence, it is easy to cause the initial position of the workpiece Changes will lead to changes in the positioning center of the workpiece, which will eventually require the staff to perform secondary centering or affect the precision quality of the finished product.
