Embodiment 1

[0041] Such as Figure 1-3 The automatic positioning fixture system shown includes a machine tool base 1 and a working guide rail 2 and a fixture guide rail 3 installed in parallel on the machine tool base 1. The working guide rail 2 and the fixture guide rail 3 are separated by a certain distance; The dragging module 4 of 41, the pressing pin 41 is a retractable structure, and the dragging module 4 is controlled by the numerical control system; one end of the fixture guide rail 3 is fixedly installed with the end face positioning fixture 5, and the other end is slidably installed with the end face clamping fixture 7, between the two A plurality of automatic positioning fixtures 6 with detent plates 61 are slidably installed on the fixture guide rail 3. The depressor plates 61 match the detent pins 41, and the depressor pins 41 are telescopically installed on the side of the drag module 4 facing the fixture guide rail 3. The depressing plate 61 is fixedly installed on the side...

Embodiment 2

[0062] On the basis of Embodiment 1, the bottom of the automatic positioning fixture 6 is provided with a protective device 62 for clamping or loosening the fixture guide rail, such as Figure 4 As shown, the protection device 62 is a pneumatic or hydraulic or electric actuator, and the protection device 62 can be a guide rail clamp. When the protection device 62 is opened, the automatic positioning fixture 6 can move freely on the fixture guide rail 3 , and when the protection device 62 is closed, the position of the automatic positioning fixture 6 on the fixture guide rail 3 is locked.

[0063] The automatic positioning fixture system 6 also includes a positioning module, and the positioning module includes a tool path post-processing module, a machine tool fixture PLC and a numerical control system positioning subroutine module; Process the file, and transmit the generated processing file to the CNC system; the CNC system positioning subroutine module is located in the CNC ...

Abstract

The invention discloses an automatic positioning clamp system and a positioning method thereof. The automatic positioning clamp system comprises a machine tool base and further comprises work guide rails and clamp guide rails, wherein the work guide rails and the clamp guide rails are arranged on the machine tool base in parallel. Each work guide rail is provided with a dragging module with a press pin in a sliding manner, wherein the press pin is of a telescopic structure. An end face positioning clamp is fixedly arranged at one end of each clamp guide rail, an end face clamping clamp is arranged at the other end of each clamp guide rail in a sliding manner, wherein a plurality of automatic positioning clamps with press pin plates are arranged between the two clamps in a sliding manner, and the press pin plates are matched with the press pin. According to the provided automatic positioning clamp system and the positioning method thereof, universality of the clamps can be effectively improved, the positions of the multiple automatic positioning clamps are automatically arranged according to the size of workpieces, the error of manual positioning clamps is reduced, and the positioning precision and the efficiency of the clamps are improved.

Description

technical field [0001] The invention belongs to the technical field of machine tool fixtures, in particular to an automatic positioning fixture system and a positioning method thereof. Background technique [0002] In the current five-axis processing machine tools, especially large-scale five-axis profile processing machine tools, the workpiece size is large and the rigidity is low, and more support and clamping fixtures are required. At present, most of them use special fixtures, or manually measure and position fixtures. There will be large errors in the manual measurement and recording process, which may cause a collision accident, and the manual placement of fixtures is a waste of time. In order to improve the versatility of fixtures, processing safety and processing efficiency, it is of great practical value to design an automatic positioning fixture system. Contents of the invention [0003] In order to solve the above technical problems, the present invention provi...
