Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to a cylinder type precise positioning and fastening device. Background Art

[0002] During the processing of products by automated equipment, not only do they need to be fixed, but they also need to be adjusted in position by a positioning device before fixation, so that the products are adjusted to the appropriate processing position to avoid deviation of the processing position, resulting in large tolerances after the product is processed, making the product unusable.

[0003] Some products require bonding during processing. The products that need to be bonded are driven by manually turning the handwheel to rotate the screw, which in turn causes the base to move the product until it is bonded. However, the manually turned handwheel may rotate after bonding, causing the base to move backward and drive the product to move together, resulting in the product not being tightly fitted, which affects the processing progress to a certain extent. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a cylinder-type precise positioning and fastening device, which has the advantages of tight fitting and solves the problem that the manually rotated hand wheel may rotate after fitting, thereby causing the base to move backward and drive the product to move together.

[0006] Furthermore, a first positioning hole for the output shaft of the first cylinder to pass through is opened on the back side of the base, and the output shaft of the first cylinder is slidably connected to the base through the first positioning hole.

[0007] Furthermore, a second positioning hole for the second cylinder output shaft to pass through is opened on the back side of the base, and the output shaft of the second cylinder is slidably connected to the base through the second positioning hole.

[0009] Furthermore, the upper surface of the base is provided with two first nut grooves, and the lower surface of the base is provided with a first through hole located at the lower side of the first nut groove.

[0010] Furthermore, the upper surface of the base is provided with two second nut grooves, and the lower surface of the base is provided with a second through hole located at the lower side of the second nut groove.

[0011] Furthermore, the two first nut slots are respectively located on the left and right sides of the first positioning block, and the two second nut slots are respectively located on the front and back sides of the second positioning block.
