Embodiment Construction
[0015] Below in conjunction with accompanying drawing and embodiment example, the present invention will be further described:
[0016] like figure 1 A high-precision automatic clamp shown includes a clamp base 1, a spring outer cover 2 arranged on the upper part of the clamp base 1, a spring inner sleeve 3 arranged inside the spring outer sleeve 2, a spring collet 4 arranged inside the spring inner sleeve 3, The positioning core 5 and the cylinder 6 are arranged inside the collet 4 .
[0017] In this embodiment: a pair of uprights 7 are arranged on the upper part of the fixture base 1, and the uprights 7 are used as the support of the whole fixture, and are arranged on the left and right sides. Connected with the spring jacket 2, the spring collet 4 is connected to the spring jacket 2 through its external thread, thereby forming a whole, and the positioning core 5 is connected to the spring collet 4 through threads for positioning the workpiece. The cylinder 6 is connected ...

The invention relates to a high-precision automatic clamp, which comprises a clamp base, a spring outer sleeve arranged on the upper part of the clamp base, a spring inner sleeve arranged inside the spring outer sleeve, and a spring clamp arranged inside the spring inner sleeve. Head, positioning core and cylinder arranged inside the collet, the outer spring is connected with the inner sleeve of the spring and the collet, the positioning core is connected with the collet, the The cylinder is connected with the positioning core, when the cylinder pulls the positioning core downward, the spring collet is locked downward; when the cylinder pulls the positioning core upward , the spring collet is released upwards. The invention has a high degree of automation, reduces the clamping time of the workpiece, has high positioning accuracy, and the processed parts have high precision and can achieve roundness 0.3um ,Cylindricity 1um , to meet the requirements of high speed and high sales processing.
Description
technical field [0001] The invention relates to a high-precision automatic fixture. Background technique [0002] At present, there are many types of fixtures in the field, but their structures and clamping convenience are uneven. The processing of cylindrical workpieces requires high roundness and cylindricity. Although fixtures with complex structures can guarantee processing accuracy, but The clamping is cumbersome and increases the operating time, but the clamping is convenient and often fails to meet the accuracy requirements. Contents of the invention [0003] The purpose of the present invention is to provide a high-precision automatic fixture. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A high-precision automatic clamp, comprising a clamp base, a spring outer sleeve arranged on the upper part of the clamp base, a spring inner sleeve arranged inside the spring outer sleeve, a spring collet arran...
