It is usually made of various materials such as metal, plastic, etc., and is customized according to specific application scenarios and requirements. The design of the jig takes into account the shape, size, weight of the workpiece and various factors in the processing or detection process to ensure that the workpiece can be stably and accurately positioned and fixed. In manufacturing, maintenance and detection and other links, the jig plays a crucial role, which can reduce the error of manual operation, improve production efficiency, and protect the workpiece from damage at the same time. Different types of jigs have different functions and characteristics, such as mechanical jigs, pneumatic jigs and hydraulic jigs, etc., which are suitable for different production environments and requirements. Therefore, the jig is an important and indispensable tool in industrial production. In the existing patent application with the application number CN202321764111.0, a combined fixture is proposed. Although it can freely adjust the position of the clamping block according to the size of the workpiece to be processed, so as to clamp and fix workpieces of different sizes, the bottom plate of this fixture has a certain volume and is an integral structure, resulting in certain inconvenience in the storage and transportation of the fixture. Therefore, a combined workpiece processing and positioning jig is needed to solve the above problems. Content of the Utility Model

There are two workpiece fixing pressing plates which are respectively fixedly installed at the upper ends of the telescopic rods of the two fixed cylinders. A connecting component is installed on the two groups of fixed jigs. The connecting component consists of a connecting substrate, mounting connecting rods, fixed springs and fixed teeth. There are two connecting substrates which are respectively fixedly installed at both ends of the fixed springs. There are four mounting connecting rods which are symmetrically fixedly installed in pairs at both ends of the two connecting substrates.

Detailed Embodiments

[0018] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a combined workpiece processing positioning fixture includes two sets of fixed fixtures 1. The fixed fixture 1 is composed of a bottom substrate 3, an upper substrate 4, a connecting bracket 5, a fixed cylinder 6 and a workpiece fixing pressing plate 13. The upper substrate 4 is located above the bottom substrate 3. The connecting bracket 5 connects the bottom substrate 3 and the upper substrate 4 together. There are two fixed cylinders 6 symmetrically inserted on the upper substrate 4. There are two workpiece fixing pressing plates 13 respectively fixed at the upper ends of the telescopic rods of the two fixed cylinders 6. A connecting component 2 is installed on the two sets of fixed fixtures 1. The connecting component 2 is composed of a connecting substrate 9, mounting connecting rods 10, fixed springs 11 and fixed teeth 12. There are two connecting substrates 9 respectively fixed at both ends of the fixed spring 11. There are four mounting connecting rods 10 and they are symmetrically fixed in pairs at both ends of the two connecting substrates 9. There are several fixed teeth 12 evenly fixed at one end of the four mounting connecting rods 10. When in use, the workpiece can be placed on the upper ends of the two upper substrates 4 of the two sets of fixed fixtures 1, and then the fixed cylinder 6 is started, so that the workpiece fixing pressing plate 13 is pressed on the upper end of the workpiece, and at this time the fixing of the workpiece is completed; the distance between the two sets of fixed fixtures 1 can be adjusted according to the size of the workpiece. The method is to first squeeze the two connecting substrates 9 on the connecting component 2, so that the two connecting substrates 9 approach each other. At this time, the fixed spring 11 will be compressed by the two connecting substrates 9. At the same time, the mounting connecting rods 10 and the fixed teeth 12 will move together with the connecting substrate 9, and finally until the fixed teeth 12 are removed from the tooth slot 8. At this time, the fixing of the fixed fixture 1 and the connecting component 2 will be released. Then the two sets of fixed fixtures 1 can be moved closer to or away from each other until the fixture can fix the workpiece. Then the connecting substrate 9 can be released. At this time, under the elastic force of the fixed spring 11, the two connecting substrates 9 will move away from each other, and finally the fixed teeth 12 will be stuck in the tooth slot 8. At this time, the adjustment of the distance between the two sets of fixed fixtures 1 is completed.

[0020] Finally, by setting a workpiece processing positioning fixture composed of two sets of fixed fixtures 1 and a connecting component 2, the fixture can not only clamp and fix workpieces of different sizes, but also can be disassembled to reduce the volume, thus bringing convenience to the storage and transportation of the fixture. By setting the connecting component 2 and making it cooperate with the connecting through hole 7 and the tooth slot 8 on the fixed fixture 1, the disassembly and assembly of the fixture can be relatively simple and convenient, thus improving the disassembly and assembly efficiency of the fixture.

[0021] Furthermore, the connecting bracket 5 on the fixing fixture 1 is fixedly connected to both the bottom substrate 3 and the upper substrate 4, the fixing cylinder 6 is fixedly connected to the upper substrate 4, the workpiece fixing pressing plate 13 is located above the upper substrate 4, two connecting through holes 7 are symmetrically formed in the bottom substrate 3 of the fixing fixture 1, the connecting through holes 7 penetrate through the inside and outside of the bottom substrate 3, a plurality of fixing teeth 12 are uniformly formed on the outer inner wall of the connecting through hole 7, the connecting substrate 9 and the fixing spring 11 on the connecting component 2 are both located between the two groups of fixing fixtures 1, the mounting connecting rod 10 on the connecting component 2 is movably inserted into the connecting through hole 7 formed in the bottom substrate 3, and the fixing teeth 12 on the connecting component 2 are engaged in the tooth grooves 8 formed on the outer inner wall of the connecting through hole 7. When it is necessary to adjust the distance between the two groups of fixing fixtures 1 or disassemble and store or transport this jig, the fixing between the fixing fixture 1 and the connecting component 2 can be released first. At this time, only the two connecting substrates 9 need to be moved closer to each other, so that the connecting substrate 9 drives the mounting connecting rod 10 and the fixing teeth 12 to move inward, and finally the fixing teeth 12 are removed from the tooth grooves 8. At this time, the fixing between the fixing fixture 1 and the connecting component 2 is completed, and then the fixing fixture 1 and the connecting component 2 can be relatively moved to adjust the distance between the two groups of fixing fixtures 1 or disassemble the fixing fixture 1 and the connecting component 2.
