Grinder fixture for precise and efficient grinding of injection needle tip and operation method thereof

Abstract

The invention provides a grinder jig for precise and efficient grinding of injection needle points, which is installed on a grinder and used to grind a row of needle heads at the same time after rotating the angle, including a mounting plate, a bottom plate, an adjustment mechanism, a transmission mechanism, The middle plate and the matching mechanism, the adjustment mechanism includes a flip plate, a flip shaft seat, a fixed block, a regulator, a backing plate, a movable block, and a shift fork, and the movable block slides on the backing plate along the extension direction of the flip plate; the transmission The mechanism includes a gear rack, a lower gear, and an upper gear that are matched in sequence. After the movable block slides along the backing plate, the rack drives the lower gear and then drives the upper gear to rotate. The upper gear is connected with a mounting groove on the opposite side of the middle plate. The slots are matched to connect the needle seat; the matching mechanism includes a matching block, a cover plate, and a moving fork. The invention has exquisite structure, high-precision parts, and simple transmission, so that the injection needles can maintain high stability in translational and rotational dimensions, and one group can be polished at the same time, with high grinding quality.

Description

technical field [0001] The invention belongs to the field of precision mechanical equipment, and in particular relates to a grinder jig for precisely and efficiently grinding injection needle points and an operating method thereof. Background technique [0002] Injection needles include needle bases and injection needles. In the production process of injection needles, the needles of injection needles need to be polished to make the needle tip smooth and sharp to meet medical requirements. Due to its fineness, the grinding of injection needle tip is mainly done by hand at present. [0003] The manual grinding step has the advantage of being flexible, does not require equipment assistance, and saves equipment costs. However, medical injection needles require high precision. Manual grinding is not only inefficient, but also the yield of finished products cannot be guaranteed. Skilled labor is required and the dependence on labor is required. It is difficult to meet the flexib...

Problems solved by technology

In this case, the needle tip of an injection needle can be regarded as a point. The grinding machine is easy to operate and the accuracy can be guaranteed, but the efficiency improvement of each grinding one is limited compared with manual grinding.
