[0018] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0019] Embodiment 1: An extrusion positioning assembly comprises: a fixed seat 9, a groove 1 is provided on the end surface of one end of the fixed seat 9, one end of an elastic member 2 is embedded in the groove 1 and contacts with the bottom surface of the groove 1, the other end of the elastic member 2 is connected to a push block 3 located outside the fixed seat 9, when the elastic member 2 is in a naturally relaxed state, a first gap 71 is formed between the surface of the push block 3 facing the fixed seat 9 and the fixed seat 9.

[0020] A mounting hole 4 that penetrates the groove 1 is provided on the end face of the other end of the above-mentioned fixed seat 9. One end of a movable rod 5 passes through the mounting hole 4 and the groove 1 in sequence and is connected to the push block 3. The other end of the movable rod 5 that is in sliding contact with the inner wall of the mounting hole 4 is connected to a retaining ring 6 arranged on the outside of the fixed seat 9. The length of the movable rod 5 between the push block 3 and the bottom surface of the groove 1 is shorter than the length of the elastic member 2 in a naturally relaxed state, so that the elastic member 2 mounted on the outside of the movable rod 5 is always in a compressed state.

[0021] When the retaining ring 6 is pressed and contacted with the end surface of one end of the fixing seat 9, a second gap 72 is formed between the surface of the push block 3 facing the fixing seat 9 and the fixing seat 9, and the second gap 72 is smaller than the first gap 71;

[0022] The movable rod 5 is fixedly connected to the push block 3 and the retaining ring 6 by bolts; a gasket 8 is arranged between the movable rod 5 and the push block 3;

[0023] When in use, the relative movement between the fixed seat and the workpiece to be clamped and positioned causes the push block to move along with the fixed seat toward the workpiece until it contacts the workpiece surface;

[0024] The elastic member 2 is a spring. Before the push block contacts the workpiece, the spring in the extrusion state is not subjected to external force. The retaining ring is pulled by the movable rod to maintain extrusion contact with the end surface of one end of the fixed seat, and at this time, the interval formed between the push block and the fixed seat is the largest.

[0025] When the push block contacts the workpiece, it is subjected to the reaction force from the workpiece and squeezes the spring, pushing the movable rod to move so that the retaining ring is separated from the fixed seat and the interval between the push block and the fixed seat is reduced, and at the same time, the elastic extrusion positioning of the workpiece is achieved. In this process, the elastic part in the extrusion state provides a certain pre-pressure for the push block to improve the stability of the push block at the moment of contact with the object, and the elastic part is limited and guided by the movable rod to avoid the situation where the push block is offset and cannot contact the object surface due to deformation of the elastic part.

[0026] Embodiment 2: An extrusion positioning assembly, comprising: a fixed seat 9, a groove 1 is formed on the end surface of one end of the fixed seat 9, one end of an elastic member 2 is embedded in the groove 1 and contacts the bottom surface of the groove 1, the other end of the elastic member 2 is connected to a push block 3 located outside the fixed seat 9, when the elastic member 2 is in a naturally relaxed state, a first gap 71 is formed between the surface of the push block 3 facing the fixed seat 9 and the fixed seat 9;

[0027] When in use, the relative movement between the fixed seat and the workpiece to be clamped and positioned causes the push block to move along with the fixed seat toward the workpiece until it contacts the workpiece surface;

[0028] When the push block contacts the workpiece, it receives the reaction force from the workpiece and compresses the spring, so that the distance between the push block and the fixed seat is reduced, and at the same time, the elastic extrusion positioning of the workpiece is achieved.

[0029] A mounting hole 4 that penetrates the groove 1 is provided on the end face of the other end of the above-mentioned fixed seat 9. One end of a movable rod 5 passes through the mounting hole 4 and the groove 1 in sequence and is connected to the push block 3. The other end of the movable rod 5 that is in sliding contact with the inner wall of the mounting hole 4 is connected to a retaining ring 6 arranged on the outside of the fixed seat 9. The length of the movable rod 5 between the push block 3 and the bottom surface of the groove 1 is shorter than the length of the elastic member 2 in a naturally relaxed state, so that the elastic member 2 mounted on the outside of the movable rod 5 is always in a compressed state.

[0030] The elastic member 2 is a spring. Before the push block contacts the workpiece, the spring is not subjected to external force, and the interval formed between the push block and the fixed seat is the largest.

[0031] A gasket 8 is arranged between the movable rod 5 and the push block 3 .

[0032] At least one edge of the push block 3 has a folded edge portion 31 extending along the axial direction of the movable rod 5 .

[0033] The surface of the folded edge portion 31 facing the fixing seat 9 is in sliding contact with the outer surface of the fixing seat 9 .

[0034] One side of the main body 91 of the fixing seat 9 has an external connection portion 92 for connecting to the outside.

[0035] By adopting the above-mentioned extrusion positioning component, it is possible to achieve elastic extrusion positioning of the object to be positioned through the extension and contraction of the push block and the elastic member, thereby avoiding damage or position displacement of the object due to hard contact, and improving the stability and reliability of positioning the object; further, it is possible to provide a certain pre-pressure to improve the stability of the push block at the moment of contact with the object, and effectively avoid the situation where the push block is offset due to deformation of the elastic member and cannot contact the surface of the object, thereby further improving the stability of object clamping.

[0036] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
