4results about How to "Affect positioning accuracy" patented technology

The utility model relates to a positioning device of vertical frame belongs to the field of automobile manufacturing technology, it includes the fixed frame and two stand column units for positioning vertical frame, the vertical frame includes bottom crossbeam, top crossbeam and two frame stands between bottom crossbeam and top crossbeam, bottom crossbeam is set up on the fixed frame through the sliding mechanism, under the action of sliding mechanism, vertical frame can move between initial position and jointing position, the stand column unit is located in the side of frame stand for positioning frame stand. The sliding mechanism includes rack, gear and sliding motor of driving gear rotation that are engaged with rack, the utility model simple structure, convenient operation, the positioning of vertical frame is stable, safe and reliable, guarantees the positioning accuracy of vertical frame, and different pincers can be installed on vertical frame and positioned, to satisfy the flexible jointing production requirement of automobile.

This utility model discloses a laser cutting table blade structure with positioning steps, relating to the field of laser cutting equipment technology. It includes: a support base and a blade assembly connected to the support base. The support base includes interconnected horizontal beams and vertical beams, which form a support space around each other. The blade assembly includes a straightedge blade and a cutting blade. Positioning steps are machined at both ends of the straightedge blade to position the placed plate material, ensuring the quality of laser cutting. Compared to traditional independently installed split straightedges, this structure significantly improves impact resistance, is simple and reliable, and avoids straightedge deformation affecting positioning accuracy. Furthermore, it eliminates the need for repeated disassembly and assembly, effectively guaranteeing the positioning accuracy of the plate material.

This invention belongs to the field of welding fixtures and provides a handrail welding fixture, including: a fixture table; a positioning mechanism, an anti-detachment mechanism, and an auxiliary mechanism. The auxiliary mechanism includes a reference block, a first positioning bead, and a second positioning bead. On the reference block, a first reference surface is provided on the side opposite to the first positioning bead, and a second reference surface is provided on the side opposite to the second positioning bead. Both the first and second positioning beads are movably disposed within the reference block and can abut against the inner wall of a reference hole. Compared with the prior art, the advantage of this invention is that by using a single driving source to drive the first and second positioning beads against the inner wall of the reference hole, the first and second positioning surfaces are precisely fitted with the first and second reference surfaces, respectively. This ensures that the fixed block is accurately positioned and without deviation during welding, avoiding the impact of the reference block's own processing errors on the overall positioning accuracy of the fixed block. This significantly improves the welding positioning accuracy of the handrail and ensures consistent product quality.

The utility model relates to plywood production equipment technical field, concretely is plywood production's hot press, the utility model discloses, including workbench, the upper surface fixedly connected with two supports of workbench, two the surface mounting of support has hot press head, the inner wall of workbench is equipped with clamping device, the clamping device includes two -way threaded rod, two -way threaded rod and the inner wall rotation connection of workbench, one end fixedly connected with the circular shaft of two -way threaded rod, the circular surface screw thread connection of two -way threaded rod has two sliding blocks. Solveed the pressure that hot press plate exerted to plywood when traditional hot press was carrying out hot pressing, and it was extremely easy to cause plywood to shift, and once plywood shifted, the pressure and temperature that each part suffered in the hot pressing process could not be evenly distributed, would cause plywood to appear uneven thickness, surface uneven, interlayer bonding strength deficiency etc. Quality defects, cause product quality to be difficult to reach the problem of industry standard and use demand.
