Abstract

This invention relates to hand held clamping devices that provide the desired position when assembling two or more parts. The aim of the invention is to expand the operational capabilities by clamping in the desired position of parts of various configurations and improving accuracy. The device comprises a base 1, a pressure screw 2, mounted on the base 1 measuring bars 3, which can move along the direction of action of the clamping force and swing around the axis 4, perpendicular to the direction of action of this force. For clamping, the parts 7 are installed between the measuring bars 3 and the base 1, the screw 2 is rotated and the entire bag is clamped through the bar 5. When clamping, the strips 2 self-align along the surfaces 9 of the parts 7 due to the oval hole 6 in them. 3 Il.

Description

SP

The invention relates to mechanical engineering, and more specifically to hand-held devices that provide the required arrangement when assembling two or more parts.

The purpose of the invention is to expand operational capabilities by allowing parts of varying thickness to be bonded over surfaces located at variable angles and the direction of clamping force, and to improve the fixing accuracy of the parts to be fastened relative to each other by eliminating parts skewing due to their different thickness and location of the fastened parts. details at different angles.

FIG. 1 shows the device, a general view; in fig. 2 - the same, with the mode of figured details; in fig. 3 is a section A-A in FIG. 2

The device for fixing the parts comprises a base 1, a pressure screw 2 mounted on the base 1 of the measuring bars 3. The measuring bars 3 are mounted on the base 1 with the possibility of moving along the direction of action of the clamping force and rotation around axis 4 perpendicular to the direction of action of the same force. Extreme bar 5 performs the role of a clamp.

In the measuring bars 3 are made oval holes 6, which provide their movement and swing. The width of each oval hole 6 is chosen not less than the diameter of the axis 4, and the length is greater than the width by the amount of change in the thickness of the fastened parts 7. In a particular case

In addition, the bars 3 can be made figured for clamping parts 7 of the lever configuration.

The device works as follows. The fastened parts 7 are installed between the base 1 and the measuring bars 3, as well as between the measuring bars 3 and 5. When screwing the screw 2 into the base 1, the bar 5 presses the 1 pack consisting of the measuring bars 3 and the fastener 2 into the base plane 8. 7. Measuring strips 3, thanks to the oval hole 6, are able to rotate and move on axes 4 along the base 1, self-aligning along the planes 9 of the fastened parts 7. Therefore, the distance between the fastened details 7 depends only on the dimensions of the dimensional slats 2 and does not depend on the thickness of the fastened parts 7. By eliminating the installation error, depending on the thickness of the parts 7, thereby increasing the accuracy of the installation of parts 7 of different thicknesses.
