Description
Technical Field
The utility model relates to a wheel hub production lathe gas tightness detects frock belongs to wheel hub production facility technical field.
Background
Hubs are generally produced by casting, which is a process in which a liquid metal is cast into a casting cavity corresponding to the shape of the part, after which it is cooled and solidified, to obtain a part or a blank. And after the hub is cast, the hub is machined by a machine tool. The positioning of the wheel hub on the machine tool is the key of the processing process, and inaccurate positioning can bring processing errors and even cause product scrapping. But in the production process of an automatic line, abnormity is difficult to avoid, and the concept of air tightness detection and positioning accuracy is introduced according to the positioning problem in the production process of the hub.
SUMMERY OF THE UTILITY MODEL
According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: overcome prior art's not enough, provide the wheel hub production lathe gas tightness that can the short-term test wheel hub location whether accurate and detect frock to solve above-mentioned problem.
The utility model discloses a wheel hub production lathe gas tightness detection frock, including the chassis, be equipped with at least three group bases on the chassis, the outer lane of wheel hub is placed at the inboard edge position of base; an inner core is arranged in the base, an airtight hole is formed in the center of the inner core and is communicated with a main air passage in the base plate, an air source interface of the main air passage is connected with an air source, a compressed air flow sensor is arranged between the air source interface and the air source, and the sensor is electrically connected with an alarm device; the top of the base is provided with a pressing block, the pressing block is fixedly connected with the positioning column, and the pressing block and the positioning column respectively press the hub and the airtight hole by means of dead weight.
During processing, the base supports and positions the hub, when a workpiece (hub) is placed in place, the pressing block is rotated by an operator, the pressing block utilizes self weight, the bottom of the pressing block is contacted with the top surface of the edge of the hub, the bottom of the positioning column is contacted with the top surface of the airtight hole at the moment, the airtight hole is completely blocked, if the flow sensor detects that no compressed air passes through, the workpiece is proved to be placed in place, and therefore the workpiece is placed in place to be detected. On the contrary, if the workpiece is not placed in place, the airtight hole leaks air, the alarm device gives an alarm to remind workers of checking abnormity.
In order to stabilize the hub, preferably, the number of the bases is four, and the bases are uniformly distributed at the periphery of the hub in a circumferential array.
Preferably, the number of the main air passages is two, and each main air passage is connected with two airtight holes. Of course, in the case of sufficient air supply, a main air passage can be provided to connect all the airtight holes.
Preferably, the diameter of the airtight hole is 1 mm.
Compared with the prior art, the utility model beneficial effect who has is:
wheel hub production lathe gas tightness detect frock, whether can the short-term test wheel hub location accurate, can not only improve the production stability of product greatly, still reduced workman's intensity of labour, saved the time that detects the operation, improved production efficiency greatly, had good development prospect.
Drawings
FIG. 1 is a schematic sectional view of the present invention;
fig. 2 is a schematic view of the overall structure of the present invention;

Detailed Description
The invention will be further described with reference to the following examples:
as shown in the figures, the air tightness detection tool for the wheel hub production machine tool comprises a chassis 1, at least three groups of bases 2 are arranged on the chassis 1, and the outer ring of a wheel hub 6 is placed at the edge position of the inner side of each base 2; an inner core 3 is arranged in the base 2, an airtight hole 8 is arranged in the center of the inner core 3, the airtight hole 8 is communicated with a main air passage 7 in the chassis 1, an air source interface 9 of the main air passage 7 is connected with an air source, a compressed air flow sensor is arranged between the air source interface 9 and the air source, and the sensor is electrically connected with an alarm device; the top of the base 2 is provided with a pressing block 5, the pressing block 5 is fixedly connected with the positioning column 4, and the pressing block 5 and the positioning column 4 respectively press the hub 6 and the airtight hole 8 by means of self weight.
Wherein, the quantity of base 2 is four groups, takes the form of the circumference array evenly distributed in the periphery position of wheel hub 6. Two main air ducts 7 are arranged, and each main air duct 7 is connected with two airtight holes 8. The diameter of the airtight hole 8 is 1 mm.
In other embodiments, a main air passage 7 may be provided to connect all the airtight holes 8 when the air supply is sufficient.
The detection principle is as follows:
during the processing, the base 2 supports and positions the hub 6, when a workpiece (the hub 6) is placed in place, the pressing block 5 is rotated by an operator, the pressing block 5 is dead-weight, the bottom of the pressing block 5 is in contact with the top surface of the edge of the hub 6, the bottom of the positioning column 4 is in contact with the top surface of the airtight hole 8 at the moment, the airtight hole 8 is completely blocked, if the flow sensor detects that no compressed air passes through, the workpiece is placed in place, and therefore the workpiece is placed in place to detect. On the contrary, if the workpiece is not placed in place, the airtight hole 8 leaks air, and the alarm device gives an alarm to remind workers of checking abnormity.
