Problems solved by technology

Fixtures are easy to cause deviation during the transmission process. If you do not make adjustments after arriving at the assembly station and directly perform operations such as retrieving materials, the workpiece will also be displaced during assembly, which will affect the yield, especially for products that require high precision. Need to ensure its accuracy

Embodiment Construction

[0031] In the following, the technical solution of the present invention will be further explained through the embodiments and the accompanying drawings. In order to clearly show the cooperation of the top positioning mechanism 1, the reclaiming mechanism 3 and the jig 2, Figure 7 ~ Figure 9 Hidden fixture track 4.

[0032] Such as figure 1 Shown is a three-dimensional view of the high-precision fixture positioning mechanism of the present invention, including a fixture with a workpiece 24, a fixture rail 4 for conveying and assembling the fixture 2, a top positioning mechanism 1 and a fixture 2 for suction Reclaiming mechanism 3 of the upper workpiece 24.

[0033] Such as image 3 As shown, the two pairs of opposite edges of the jig 2 are each provided with a positioning slot 21 extending upward from the bottom and a positioning slot 22 extending downward from the top. Such as Figure 5 As shown, the jig rail 4 is provided with a jacking hole 41 whose area and position are at l...

Abstract

The invention discloses a high-precision fixture positioning mechanism and a high-precision fixture positioning method based on vertical and horizontal positioning error compensation. The high-precision fixture positioning mechanism comprises a fixture with a workpiece, a fixture railway used for transporting and assembling the fixture, an upward jacking positioning mechanism and a material taking mechanism which is used for attracting the workpiece on the fixture; a first positioning clamping groove which extends upwards from a bottom is arranged on each of the two pairs of opposite edges of the fixture; the upward jacking positioning mechanism is arranged below a jacking hole, and comprises four jacking inserting blocks which are in one-to-one correspondence with the positioning clamping grooves and are adapted to the positioning clamping grooves in sizes, and a first driving device which drives the jacking inserting blocks to move longitudinally; the first driving device drives the jacking inserting blocks to penetrate through the jacking hole and are inserted into the respective corresponding positioning clamping grooves; the position of the fixture is adjusted to align with the material taking mechanism along with the cooperation of the first positioning clamping groove and the jacking inserting blocks. According to the high-precision fixture positioning mechanism and the high-precision fixture positioning method based on the vertical and horizontal positioning error compensation, the horizontal position of the fixture can be adjusted, an error can be compensated, and the assembling precision can be improved based on vertical and horizontal positioning.

Description

Technical field [0001] The invention relates to fixture positioning, in particular to a high-precision fixture positioning mechanism and method based on vertical and horizontal positioning error compensation. Background technique [0002] In the process of assembling the workpiece, the workpiece is processed between different procedures through the jig, such as reclaiming and assembling. The jig is easy to cause deviation during the transfer process. If the workpiece is directly reclaimed without adjustment after reaching the assembly station, the workpiece will also be offset during assembly, which will affect the yield, especially for products with high precision requirements. More need to ensure its accuracy. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a high-precision fixture positioning mechanism and method that can adjust the horizontal position of the fixture based on the vertical and horizontal positioning af...
