Abstract

The utility model discloses a hub leak tester. The hub leak tester comprises a bracket, a fastening device, a control box, a cylinder, a water box and a counting device; wherein the cylinder is fixed at the top and the bottom of the bracket; a cylinder connecting seat is fixed in the middle of an upper pressure plate of the fastening device; the fastening device is located above the water box and fixed at the bottom of an upper plate of the bracket by a fixing shaft; the fastening device consists of the upper pressure plate and a work-piece support plate; the cylinder connecting seat is fixed at the bottom of the water box and fixedly connected with the cylinder at the bottom of the bracket; a sensing end of the counting device is installed in the water box; a counting display is arranged on the control box; and the counting device comprises a normal counter and an abnormal counter. The hub leak tester has the beneficial effects of ensuring the accuracy of the leak test result so as to greatly avoid the possibility of outflow of air-leaking work-pieces; and moreover, whether a leak test is carried out to each of the work-pieces can be acquired from the normal counter so as to avoid any leak, and the operation is more visualized and efficient.

Description

A kind of wheel hub leakage tester

Technical field

The utility model relates to the device of measuring workpieces sealing, relates in particular to a kind of wheel hub leakage tester that has counting assembly.

Background technology

After all wheel hubs process at present, all need carry out performing leak test to each workpiece.Method commonly used now is as shown in Figure 1, is to put into liquid to workpiece, in workpiece, suppresses, and the operator observes workpiece, and whether bubbling is leaked gas, and judges according to bubbling situation around the workpiece whether workpiece leaks gas.Though whether this mode can be judged product qualified, the not enough situation of pneumatics appears, and the bubbling situation is can't see at the gas leakage position, and operator's erroneous judgement easily is certified products, thereby lets unacceptable product flow to market.And, can't decision operation person whether each workpiece all have been carried out leak test.

Summary of the invention

The utility model provides a kind of wheel hub leakage tester in order to overcome the problem that exists in the prior art, through the mode of counting assembly is being set, occurs the situation of erroneous judgement when avoiding pneumatics not enough, also is convenient to the quantity that the operator writes down specification product.

The utility model adopts following technical scheme to realize:

A kind of wheel hub leakage tester; Comprise support, fastener, control box, cylinder and water tank; Said cylinder is fixed on a top of the trellis and a frame bottom, and the center fixed of the top board of said fastener has the cylinder Connection Block, and said fastener is positioned at the water tank area top is fixed on the support upper plate through stationary shaft bottom; Said fastener is made up of top board and workpiece supporting plate, and the said water tank bottom fixedly cylinder of cylinder Connection Block and frame bottom is affixed.Also comprise counting assembly, the induction end of said counting assembly is installed in the water tank, and count display is arranged on the control box.

Preferably, said counting assembly comprises normal counter and anomalous counts device.

The beneficial effect of the utility model is, a kind of wheel hub leakage tester is provided with normal counter and anomalous counts device, if workpiece leak test process condition is normal, normal counter adds 1; If when the workpiece pneumatics was lower than setting value, the anomalous counts device just counted 1; The operator can judge whether workpiece leaks gas from bubbling situation and two aspects of anomalous counts device, guarantees leak test result's accuracy rate, has avoided the possibility of gas leakage workpiece outflow greatly; In addition, the operator also can understand whether all workpiece have all passed through leak test from normal counter, has avoided omission, and operating process is more directly perceived efficient.

Description of drawings

Fig. 1 is the prior art constructions synoptic diagram;

Fig. 2 is the structural representation of the embodiment of the utility model;

Drawing reference numeral explanation: 1 support; 2 fasteners; 3 control boxs; 4 cylinders; 5 water tanks; 6 counting assemblys.

Embodiment

Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.

Please refer to Fig. 2, a kind of wheel hub leakage tester comprises support 1, fastener 2, control box 3, cylinder 4 and water tank 5.Cylinder 4 is fixed on support 1 top and support 1 bottom; The center fixed of the top board of fastener 2 has cylinder 4 Connection Blocks; Fastener 2 is positioned at top, water tank 5 zone is fixed on support 1 upper plate through stationary shaft bottom; Fastener 2 is made up of top board and workpiece supporting plate, and it is affixed that water tank 5 bottoms are fixed with the cylinder 4 of cylinder 4 Connection Blocks and support 1 bottom.Also comprise counting assembly 6, the induction end of counting assembly 6 is installed in the water tank 5, and count display is arranged on the control box 4.Counting assembly 6 comprises a normal counter and an anomalous counts device.

The operator is during according to standard operation, and after earlier workpiece being placed on the leakage tester center, starting, fastener 2 descends; Oil pressure reaches to be set when requiring, and workpiece begins inflation, and tank begins to rise when pneumatics reaches 4.5kg/cm2; After rising put in place and stops 1 minute, the leakage tester lamp of 3 300W was bright, and whether the bright back of lamp operator observes workpiece leaks gas; If gas leakage is marked at the gas leakage position, after confirming to accomplish, press reset key; Leakage tester restPoses, and workpiece is taken out, and accomplishes a workpiece leak test overall process and moves normal rolling counters forward and add 1; Otherwise if in leak test bucket uphill process, when pneumatics was lower than 4.5kg/cm2, anomalous counts device counting just added 1, and at this moment the operator will be to this workpiece by front standard conditions leak test more from the beginning to the end.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; In form with on the details the utility model is made various variations, be the protection domain of the utility model.

Claims
