Workpiece-pressing jig

Abstract

The invention discloses a workpiece-pressing jig. The jig comprises a jig table (1), an air cylinder (2) and a pressure plate (6). The jig is characterized in that the jig also comprises a guide sleeve (3), a fixing seat (4), a guide pin (5) and a pressure plate locking device, wherein the guide sleeve (3) is arranged on the cylinder shaft (2.1) of the air cylinder (2), the fixing seat (4) is used to fix the guide sleeve (3) on the jig table (1); the guide sleeve (3) comprises a guide groove (3.1), the guide groove (3.1) comprises a spiral groove part (3.1.1) and a straight-flute part (3.1.2); the guide pin (5) penetrates through the guide groove (3.1) to be fixed on the cylinder shaft (2.1); and the pressure plate (6) is locked on the end of the cylinder shaft (2.1) by the pressure plate locking device. By using the workpiece-pressing jig, the pressure plate fixed on the cylinder shaft can lean to one side so that the workpiece on the jig table can have larger space in vertical direction, the operation can be convenient and the clamping rate can be greatly improved.

Description

technical field [0001] The invention relates to a fixture, in particular to a workpiece pressing fixture. Background technique [0002] In the machining of parts, it is generally necessary to position and compress the workpiece first. At present, the commonly used workpiece clamping method usually uses nuts and bolts for compression and fixation. Although this method is simple, it is time-consuming and laborious to use. At present, there is also a compression fixture that uses cylinder locking. As power to compress the workpiece, a common structure is as follows: a pressure plate is installed and fixed at the end of the cylinder shaft. When the cylinder is opened, the workpiece is installed under the pressure plate. After positioning, the cylinder retracts to compress the workpiece. Although this structure improves the clamping speed to a certain extent and saves labor compared with the traditional nut and bolt fixing method, when in use, since the workpiece should be place...

Problems solved by technology

At present, the commonly used workpiece clamping method usually uses nuts and bolts for compression and fixation. Although this method is simple, it is time-consuming and laborious to use. At present, there is also a compression fixture that uses cylinder locking. As power to compress the workpiece, a common structure is as follows: a pressure plate is installed and fixed at the end of the cylinder shaft, and the workpiece is installed under the pressure plate when the cylinder is opened. After positioning, the cylinder retracts to compress the workpiece.

Although this structure improves the clamping speed to a certain extent and saves labor compared with the traditional nut and bolt fixing method, when in use, since the workpiece should be placed under the pressure plate, the pressure plate, as a necessary part, can be clamped in a narrow However, the space affects the clamping speed. Therefore, it is necessary to improve the clamping fixture to further increase the clamping speed.
