Abstract
The utility model relates to a special screw-turning rotary spring cutter bar. In actual production, a screw is frequently designed into a combination of threads with the same screw pitch and different thread groove depths (with equal pitch and different depths), different screw pitches and different thread groove depths (with different pitches and different depths), or different numbers of threads, so that the machining process of the screw is complex and the machining operation is complicated. The special screw-turning rotary spring cutter bar structurally comprises a cutter body (1), wherein a square hole (2) for installing a cutter blade is formed on one side of the cutter body; a screw hole (4) for installing a jackscrew (3) is formed over the square hole; a rotary shaft (5) is arranged on the other side of the cutter body; a fixing sleeve (6) is connected outside the rotary shaft; scales are carved on the fixing sleeve; and the end head of the rotary shaft is connected with a cover-shaped nut (7). The special screw-turning rotary spring cutter bar is used for turning the screw.
Description
Technical field:
the utility model relates to a kind of screw rod turning special rotary split holder.
Background technology:
screw rod is a kind of screw thread transmission campaign of itself or shaft-like machine components of power of utilizing, and is used for plastic molding equipment, like plastic material extruder, injection machine etc. more.Screw rod and machine barrel are the core components of plastic molding equipment, are the parts of heating extrusion plasticizing.The characteristics of screw rod part are that length is long, draw ratio is big, required precision is high.In actual production, it is identical that screw rod often is designed to pitch, and the thread groove degree of depth different (equidistance does not wait deeply), pitch are different, and the thread groove degree of depth is the combination of the screw thread of difference (equidistance does not wait deeply) or a difference number also.Therefore the processing technology of screw rod is complicated, complex operation.
Summary of the invention:
The purpose of
the utility model is the screw rod part according to the different structure characteristic, but provides the equidistance of various single heads of a kind of turning or bull not wait deeply, special rotary split holder that equidistance does not wait dark screw rod.
Above-mentioned purpose realizes through following technical scheme:
screw rod turning special rotary split holder; Its composition comprises: cutter hub, and a side of described cutter hub has the square hole that is used to install blade, and the vertical direction of described square hole has the screw hole that is used to install jackscrew; The opposite side of described cutter hub has gyroaxis; Described gyroaxis outside connects fixed cover, is carved with scale on the described fixed cover, and the termination of described gyroaxis connects acorn nut.
described screw rod turning special rotary split holder has two through holes on the described cutter hub, resilient sleeve is installed in described through hole the inside.
Beneficial effect:
1. the utility model according to the screw rod part of different structure characteristic, but the equidistance of the design various single heads of a turning or bull does not wait deeply, equidistance does not wait the special rotary split holder of screw rod deeply.The basic operation method of this turning screw rod special rotary split holder is to turn on the locking nut of its back; Through any adjustment knife bar angle, can process the screw thread of different lead angles, effectively increase cutter intensity and toughness; Raise labour productivity simultaneously, improve machining accuracy.
2. the utility model is through jackscrew locking cutter hub and blade, and it is convenient to change cutter head.
3. the knife bar of the utility model are fixed on the lathe cutter saddle through square fixed cover; Its installation is simple and convenient; Because fixed cover can rotate ± 30 ° by the axis on cutter hub, therefore can adjust lead angle easily, thereby enlarge the scope of application simultaneously.
The cutting force in the working angles is effectively alleviated in
4. installation of the utility model resilient sleeve on knife bar, increases cutter intensity and toughness, practices thrift cutter material, improves working (machining) efficiency and crudy.
Description of drawings:
accompanying drawing 1 is the main TV structure sketch map of the utility model.
accompanying drawing 2 is left TV structure sketch mapes of the utility model.
accompanying drawing 3 is that the K of accompanying drawing 1 is to view.
The specific embodiment:
Embodiment 1:
screw rod turning special rotary split holder; Its composition comprises: cutter hub 1; One side of described cutter hub has the square hole 2 that is used to install blade, and the vertical direction of described square hole has the screw hole 4 that is used to install jackscrew 3, and the opposite side of described cutter hub has gyroaxis 5; Described gyroaxis outside connects fixed cover 6, is carved with scale on the described fixed cover.Can adjust setting angle through the rotational fixation cover, thereby process the screw rod of different lead angles.The termination of described gyroaxis connects acorn nut 7.After treating that operation is accomplished, the acorn nut of screwing.
Embodiment 2:
described screw rod turning special rotary split holder has two through holes 8 on the described cutter hub, resilient sleeve 9 is installed in described through hole the inside.The intensity and the toughness of cutter have effectively been increased.Different according to cutting force direction and size, adjustment resilient sleeve size cushions cutting force uniformly and effectively.
Claims (2)
1. screw rod turning special rotary split holder; Its composition comprises: cutter hub is characterized in that: a side of described cutter hub has the square hole that is used to install blade, and the vertical direction of described square hole has the screw hole that is used to install jackscrew; The opposite side of described cutter hub has gyroaxis; Described gyroaxis outside connects fixed cover, is carved with scale on the described fixed cover, and the termination of described gyroaxis connects acorn nut.
2. screw rod turning special rotary split holder according to claim 1 is characterized in that: have two through holes on the described cutter hub, resilient sleeve is installed in described through hole the inside.
