Description

Device for assisting in clamping gear at gear detection center

Technical Field

The utility model relates to a check out test set technical field, especially a device that is used for supplementary clamping gear at gear detection center.

Background

Gears are one of the most widely used mechanical parts in the mechanical industry. Gear detection is a key link for ensuring the performance and quality of gear finished products. The gear detection is not only an important basis for checking and accepting the gear finished product, but also a technical guarantee for quality control of the gear in the machining and manufacturing process. When the gear detection center detects the gear, the clamping mode is that the upper tip and the lower tip of the gear detection center respectively support against two ends of the central hole of the gear, and then the drive measuring needle detects each parameter of the gear, as shown in fig. 1 and fig. 2; however, the size of an inner hole of a gear often exceeds the effective outer diameter of the tip when the inner hole of the gear is designed, so that the gear cannot be clamped during detection, and detection failure is caused. See fig. 3.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model aims at providing a gear detection center is used for assisting the device of clamping gear, can adapt to the gear of multiple hole diameter.

The embodiment of the utility model provides an in adopt following scheme to realize: the utility model provides a device that is used for supplementary clamping gear at gear detection center, include the plug, go up support, under bracing, sleeve and lock nut and constitute, the afterbody of plug is big-end-up and small for the round platform shape, and is corresponding the hole of under bracing also is the round platform shape, go up support with the under bracing is the round platform shape, go up and set up cylindrical through-hole in the support, the top of plug is attacked threadedly, the plug passes the hole of under bracing in proper order, goes up hole, sleeve of support, penetrates lock nut, the apex hole has all been seted up with lower terminal surface to the up end of plug.

In an embodiment of the present invention, the upper support and the lower support face each other at their small ends.

In an embodiment of the present invention, the tail of the mandrel is gradually increased and is also in a truncated cone shape, and the shape of the inner hole of the lower support corresponds to the matching portion of the tail of the mandrel.

The utility model has the advantages that: the utility model provides a device that is used for supplementary clamping gear at gear detection center, through the plug and install support, under bracing on the plug, go up support, under bracing round platform shape can play and adapt to different hole diameters when pressing from both sides tightly, go up support and under bracing nearer of leaving, then can press from both sides the examination gear that awaits measuring of pressing from both sides the bigger diameter hole. The function of clamping the gear with the gear inner hole exceeding the outer diameter of the center of the detection center by the detection center is achieved.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Please refer to fig. 1 to 6, the utility model provides a device that is used for supplementary clamping gear at gear detection center, constitute including plug 11, last support 13, under bracing 12, sleeve 14 and lock nut 15, the afterbody of plug 11 is big-end-up and small for the round platform shape, and is corresponding the hole of under bracing 12 also is the round platform shape, go up support 13 with under bracing 12 is the round platform shape, upward set up cylindrical through-hole in supporting 13, the screw thread has been attacked at the top of plug 11, plug 11 passes under bracing 12's hole, the hole of going up support 13, sleeve 14 in proper order, penetrates lock nut 15, the apex hole has all been seted up with the lower terminal surface to the up end of plug 11, is convenient for detect the top of central 3 and easily aims at tight plug 11.

Referring to fig. 4 to 6, in an embodiment of the present invention, the small ends of the upper support 13 and the lower support 12 face each other, so as to facilitate clamping the gear 2.

Referring to fig. 4 to 6, in an embodiment of the present invention, the tail of the mandrel 11 is gradually enlarged and also has a truncated cone shape, and the shape of the inner hole of the lower support corresponds to the matching portion of the tail of the mandrel, so as to facilitate installation and positioning.

The utility model discloses the theory of operation below has:

through the mandrel and the support and the lower support arranged on the mandrel, the truncated cone shapes of the upper support and the lower support can adapt to different inner hole diameters when being clamped, and the closer the upper support and the lower support are, the gear to be tested with the inner hole with the larger diameter can be clamped. When the device is used, the core rod is firstly arranged in the lower support, then the gear to be tested is arranged in the lower support, then the upper support is arranged in the upper support and sleeved in the sleeve, then the locking nut is screwed in the top of the core rod, and the locking nut is screwed tightly so as to clamp the gear to be tested; and finally clamping the whole core rod between two apexes of the detection center, and aligning the apex holes of the core rod with the apexes to finish clamping the gear to be tested. Therefore, the function that the detection center can clamp the gear with the inner hole exceeding the outer diameter of the center of the detection center is achieved.

The above description is only for the preferred embodiment of the present invention, and should not be interpreted as limiting the scope of the present invention, which is intended to cover all the equivalent changes and modifications made in accordance with the claims of the present invention.
