Abstract
The invention discloses a clamp which comprises a clamp body. The clamp is characterized in that the clamp body is cylinder-shaped; a concentric supporting rod is arranged on one end surface of the clamp body; an external thread is formed in the supporting rod, and the support rod is connected with a nut through the external thread; and a fixing hole is further formed in the end surface, where the supporting rod is located, of the clamp body, and an internal thread is formed in the fixing hole which is connected with a fastener provided with an external thread. A central hole of a gear penetrates through the supporting rod and is fixed on the clamp body through the nut, and then, one fastener penetrates through a positioning hole in the gear and is connected with the fixing hole, so that the gear is fixed on the clamp body; and a universal clamp such as a chuck and the like is utilized for positioning and clamping the clamp body, so that unnecessary damage to the gear due to the fact that the gear is directly clamped is prevented, the rejection rate is decreased, and the qualification rate is increased.
Description
Technical field
The present invention relates to a kind of fixture, in particular for the fixture of fixed gear, specifically, belong to mechanical field.
Background technology
Gear is the colyliform machine components that rely on the engagement transmitting torque of tooth.Gear by with other dentation machine components (as another gear, tooth bar, worm screw) transmission, can realize change rotating speed with moment of torsion, change the functions such as the direction of motion and change forms of motion.Due to advantages such as transmission efficiency are high, gearratio is accurate, power bracket is large, gear mechanism extensive use in industrial products, its design and manufacture level directly have influence on the quality of industrial products.Gear tooth mutually fastens gear and can drive another gear to rotate to transmit power.By two gears separately, also can apply chain, crawler belt, belt drives the gear on both sides and transmits power.
The loaded down with trivial details complexity of whole processing technology of gear, the clamping to gear in especially fine finishining process, will crush the gear teeth because careless slightly, causes waste product.In addition, for some gear, except processing the gear teeth, also have other machining processes, for example boring, groove milling etc., these all need to carry out reasonable clamping to workpiece in the situation that guaranteeing gear teeth health.
Summary of the invention
The technology that the present invention will solve is to provide a kind of fixture of being convenient to gear to carry out clamping.
For addressing the above problem, the invention provides a kind of fixture, comprise chuck body, it is characterized in that, described chuck body is cylindrical shape, one end is provided with concentric support bar, described support bar is provided with external screw thread, for being connected with a nut, being provided with on the end face of support bar and being also provided with a fixing hole in described chuck body, in described fixing hole, be provided with internal thread, described fixing hole and is provided with externally threaded securing member and is connected.
As of the present invention, with regard to a step, improve, also comprise a scroll chuck, described chuck body is fixed on described scroll chuck.
As of the present invention, with regard to a step, improve, described securing member is a fixed bar, and described fixed bar comprises and be provided with externally threaded thread segment, and the length of described thread segment is greater than the degree of depth of described fixing hole.
As of the present invention, with regard to a step, improve, described fixing hole is through hole.
Beneficial effect of the present invention is, the centre bore of gear is fixed in chuck body by nut through after support bar, again a securing member is connected with fixing hole through the locating hole on this gear, thereby gear is fixed in chuck body, re-use the universal fixturings such as chuck chuck body is positioned to clamping, prevent from directly clamping the unnecessary injury that gear brings to gear, reduce percent defective, improve qualification rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein: 2-scroll chuck; 4-chuck body; 6-support bar; 8-fixing hole; 10-fixed bar.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done further in detail.
As shown in Figure 1, the present invention includes chuck body 4, chuck body 4 is cylindrical shape, one end is provided with concentric support bar 6, and support bar 6 is provided with external screw thread, for being connected with a nut, in chuck body 4, be provided with on the end face of support bar 6 and be also provided with a fixing hole 8, fixing hole 8 is through hole.In fixing hole 8, be provided with internal thread, fixing hole 8 and is provided with externally threaded securing member and is connected.Securing member is a fixed bar 10, and fixed bar 10 comprises and be provided with externally threaded thread segment, and the length of thread segment is greater than the degree of depth of fixing hole 8.In addition, also comprise a scroll chuck 2 in the present invention, chuck body 4 is fixed on scroll chuck 2.
Operation principle of the present invention is as follows, the centre bore of gear is fixed in chuck body 4 by nut through after support bar 6, again a fixed bar 10 is connected with fixing hole 8 through the locating hole on this gear, fixed bar 10 comprises the screw-internal thread fit being provided with in externally threaded thread segment and fixing hole 8, thereby gear is fixed in chuck body 4, in general, the length of thread segment is greater than the degree of depth of described fixing hole 8, to guarantee connecting length.Re-use the universal fixturings such as chuck chuck body 4 is positioned to clamping, prevent from directly clamping the unnecessary injury that gear brings to gear, reduce percent defective, improve qualification rate.
Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
