Abstract
The utility model discloses a mandrel with an expandable core. The mandrel with the expandable core comprises a mandrel body (1), wherein the mandrel body (1) is formed by connecting a clamping section (1a), a cylindrical section (1b), a conical section (1c) and a screw thread section (1d) in sequence, wherein the cylindrical section (1b) is provided with a bearing seat (2) in a sleeved manner and is fixed on the cylindrical section (1b) through a locking pin (5); the conical section (1c) is provided with an elastic sleeve (3) in a sleeved manner; the taper of the inner hole of the elastic sleeve (3) is in accordance with that of the conical section (1c); one end, far away from the bearing seat (2), of the elastic sleeve (3) is tightly pressed by a locking nut (4) which is arranged on the screw thread section (1d). Through the elastic sleeve, good centering function can be played for machining and detecting of hole-carrying parts (annular members such as pinions); when the mandrel with the expandable core is used for machining and detecting products with different inner holes, replacement of the elastic sleeve and the bearing seat is only needed; the mandrel with the expandable core is convenient to operate and high in precision.
Description
Technical field
The utility model relates to machining checkout equipment, relates in particular to a kind of swollen heart mandrel for machining and detection.
Background technology
In the processing and detection of pored component (as pinion), part need to be sleeved on fixture mandrel, then clamp by scroll chuck, centering effect is bad, causes processing and accuracy of detection not to reach requirement; The different part of each internal diameter will design separately a set of mandrel, and not only cost is high, and is not easy to management.
Utility model content
The utility model aims to provide a kind of good positioning effect, swollen heart mandrel that versatility is high, only need to change processing and detection that part wherein just can be realized different inner diameters part.
For solving above technical problem, a kind of swollen heart mandrel that the utility model provides, comprise mandrel body (1), key is: described mandrel body (1) is by the gripping section being connected successively (1a), cylindrical segment (1b), conical section (1c) and thread segment (1d) form, on described cylindrical segment (1b), be set with supporting base (2) and be fixed on cylindrical segment (1b) by lock pin (5), in described conical section (1c), be set with resilient sleeve (3), the hole taper of described resilient sleeve (3) is consistent with the tapering of conical section (1c), resilient sleeve (3) compresses by the locking nut (4) being arranged on thread segment (1d) away from one end of supporting base (2).
Be preferably, on described cylindrical segment (1b), be provided with cannelure, described lock pin (5) is threaded bolt spring lock pin, is provided with the screwed hole passing through for lock pin (5) on supporting base (2), and described lock pin (5) extend in the cannelure of cylindrical segment (1b) through after supporting base (2).Select threaded bolt spring lock pin, the mounting or dismounting of the supporting base of being more convenient for.
The beneficial effects of the utility model: by resilient sleeve, processing and detection to pored component (as annular elements such as pinions), can play certralizing ability well; During to the discrepant product processing of endoporus and detection, only need change resilient sleeve, supporting base, easy to operate, precision is high.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of the utility model and exemplar.
Fig. 2 is the structural representation of Fig. 1 Elastic cover.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
The swollen heart mandrel of detection use as shown in Figure 1, is comprised of mandrel body 1, supporting base 2, resilient sleeve 3, locking nut 4, lock pin 5 etc.Mandrel body 1 consists of the gripping section 1a being connected successively, cylindrical segment 1b, conical section 1c and thread segment 1d.Mandrel body 1 is arranged on mandrel mount pad by gripping section 1a.On cylindrical segment 1b, be set with supporting base 2, and be fixed on cylindrical segment 1b by lock pin 5.Shown in Fig. 2, on conical section 1c, be set with resilient sleeve 3, the hole taper of resilient sleeve 3 is consistent with the tapering of conical section 1c.Resilient sleeve 3 compresses by the locking nut 4 being arranged on thread segment 1d away from one end of supporting base 2.
When processing and detection, exemplar 6 is sleeved on outside resilient sleeve 3, the left side of exemplar 6 is close on the right side of supporting base 2, and the elasticity of recycling resilient sleeve 3 is fixing by exemplar 6.Part for different inner diameters adds man-hour, only need to be replaced with supporting base 2 and the resilient sleeve 3 of correspondingly-sized specification, to guarantee that part can be fixed on swollen heart mandrel.
Preferably, on cylindrical segment 1b, be provided with cannelure, lock pin 5 is threaded bolt spring lock pin, is provided with the screwed hole passing through for lock pin 5 on supporting base 2, and lock pin 5 extend in the cannelure of cylindrical segment 1b through after supporting base 2.
Claims (2)
1. a swollen heart mandrel, comprise mandrel body (1), it is characterized in that: described mandrel body (1) is by the gripping section being connected successively (1a), cylindrical segment (1b), conical section (1c) and thread segment (1d) form, on described cylindrical segment (1b), be set with supporting base (2) and be fixed on cylindrical segment (1b) by lock pin (5), in described conical section (1c), be set with resilient sleeve (3), the hole taper of described resilient sleeve (3) is consistent with the tapering of conical section (1c), resilient sleeve (3) compresses by the locking nut (4) being arranged on thread segment (1d) away from one end of supporting base (2).
2. according to swollen heart mandrel claimed in claim 1, it is characterized in that: on described cylindrical segment (1b), be provided with cannelure, described lock pin (5) is threaded bolt spring lock pin, on supporting base (2), be provided with the screwed hole passing through for lock pin (5), described lock pin (5) extend in the cannelure of cylindrical segment (1b) through after supporting base (2).
