Problems solved by technology

Therefore, the thickness of the clamping part, the increased wear of the inner hole of the three-lobe chuck and the blockage of the cuttings all directly affect the clamping effect, so that there are slipping, clamping not tight, and pulling out phenomena in actual work.

Abstract

The invention provides a clamping structure for a grinding bar of a medical grinding machine. The clamping structure comprises a first sleeve tube (2), a second sleeve tube (3), a push block (42), a taper sleeve (41) and steel balls (5). The second sleeve tube (3) is provided with slotted holes (8) with the diameter of lower openings being smaller than that of upper openings, and the steel balls (5) are arranged in the slotted holes (8). The taper sleeve is connected to the second sleeve tube in a sleeving mode, is in sliding connection with the second sleeve tube and is used for limiting the steel balls (5). The push block is used for pushing the taper sleeve to move. By the adoption of the clamping structure, axial vertical rigid force can be applied to the grinding bar through the steel balls, the problem of steel ball skewing caused by vibration in the working process of the grinding machine and pressure to the steel balls by the grinding bar cannot happen, and the phenomena that the grinding bar slips, cannot be clamped tightly and cannot be pulled out due to abrasion increase of three-petal chuck inner holes and blockage by cutting objects are avoided.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a clamping structure for a grinding rod of a medical grinder. Background technique [0002] There are generally two basic ways to clamp the grinding rod of traditional medical grinding machines, one is the three-petal chuck, and the other is steel ball clamping: [0003] The three-lobe chuck is the most commonly used clamping method. The grinding head adopting this method generally includes an elastic three-lobe chuck, a rear pull rod threaded with it, a compression spring set on the rear pull rod, and a set of three Other than the long body and so on. When working, the transmission of dynamic parameters such as torque and rotational speed is completed by the friction between the inner hole surface of the elastic three-lobe chuck and the clamping part of the grinding rod. Therefore, the thickness of the clamping part, the increased wear of the inner hole of the three-lobed ch...
