Abstract
The utility model discloses a fixture, which comprises a fixture body. The fixture is characterized in that the fixture body is cylindrical, wherein a concentric support rod is arranged on one end face of the fixture body; external threads are arranged on the support rod, and are connected with a nut; a fixing hole is also formed in the end face, with the support rod, of the fixture body; internal threads are arranged in the fixing hole; the fixing hole is connected with a fastening piece with external threads. According to the fixture, the support rod penetrates through a center hole of a gear to fix the gear on the fixture body via the nut, the fastening piece penetrates through a positioning hole in the gear for fixation with the fixing hole to fix the gear on the fixture body, and a universal fixture such as a chuck is used for positioning and clamping the fixture body, so that unnecessary damage to the gear by direct clamping is prevented, the reject rate is reduced, and the qualified rate is increased.
Description
Technical field
The utility model relates to a kind of fixture, in particular for the fixture of fixed gear, specifically, belongs 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.
Utility model content
Technology to be solved in the utility model is to provide a kind of fixture of being convenient to gear to carry out clamping.
For addressing the above problem, the utility model 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 utility model, with regard to a step, improve, also comprise a scroll chuck, described chuck body is fixed on described scroll chuck.
As of the present utility model, 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 utility model, with regard to a step, improve, described fixing hole is through hole.
The beneficial effects of the utility model are, 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 utility model;
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 utility model is done further in detail.
As shown in Figure 1, the utility model comprises chuck body 4, and 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 utility model, chuck body 4 is fixed on scroll chuck 2.
Operation principle of the present utility model 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 utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
