Z-direction positioning clamp supportive of leftward-rightward rotating and fine tuning

Abstract

A Z-direction positioning clamp supportive of leftward-rightward rotating and fine tuning comprises a mounting and clamping platform and a Z-direction positioning device. A mounting and clamping groove is formed in a workbench of the mounting and clamping platform, workpieces are placed on two sides of a transverse direction in the mounting and clamping groove respectively, the Z-direction positioning device is vertically mounted in the mounting and clamping groove along a transverse center line position of the mounting and clamping groove and comprises a Z-direction driving mechanism, a Z-direction connecting shaft, a rotating shaft connecting seat, a pressing plate and a rotating shaft, the rotating shaft is fixedly connected with the pressing plate through a nut to enable the pressing plate to rotate along with the rotating shaft and to enable a gap to be reserved between the pressing plate and the upper surface of a connecting platform, and the gap is equal to amplitude of leftward-rightward rotating and fine tuning of the pressing plate. The Z-direction positioning clamp can mount and clamp multiple workpieces at one time, is not limited by own size deviation of workpiece batches and is good in clamping effect, and machining accuracy of each workpiece is guaranteed.

Description

technical field [0001] The invention relates to the field of machining fixtures, in particular to a Z-direction positioning fixture capable of turning left and right for fine adjustment. Background technique [0002] In the process of workpiece processing, it is necessary to use fixtures to clamp and position the workpiece. In small batch production and processing, the fixture structure is generally required to save costs. A workpiece is clamped and positioned, and the work efficiency is low. [0003] The existing down-pressing fixture for clamping and positioning multiple workpieces is controlled by a cylinder, and the workpieces on both sides are positioned and clamped in the slot. The workpieces on both sides must be of the same model and specification, but the workpieces There will inevitably be a certain size deviation between them. If the size error of the workpiece on both sides is greater than 1mm, the existing press-down fixture can only clamp and position the work...

[0002] In the process of workpiece processing, it is necessary to use fixtures to clamp and position the workpiece. In small batch production and processing, the fixture structure is generally required to save costs. The workpiece is clamped and positioned, and the work efficiency is low.

[0003] The existing down-pressing fixture for clamping and positioning multiple workpieces is controlled by a cylinder, and the workpieces on both sides are positioned and clamped in the slot. The workpieces on both sides must be of the same model and specification, but the workpieces There will inevitably be a certain size deviation between them. If the size error of the workpiece on both sides is greater than 1mm, the existing press-down fixture can only clamp and position the workpiece with a large size, while the workpiece with a small size on the other side cannot be clamped. , will lead to low machining accuracy for small workpieces, and the greater the error, the lower the machining accuracy
