The missing riveting detection device is characterized by also comprising a detection pin, wherein the detection pin is provided with a shaft shoulder, the tail part of the detection pin extends out of the cushion block after the shaft shoulder is buckled on the cushion block, an ejection through hole of a lower mold seat is arranged under the tail part of the detection pin, a spring is sleeved on the part of the detection pin on the shaft shoulder, the upper end of the spring props against the upper mold seat in a pressing way, and the lower end of the spring props against the shaft shoulder in a pressing way; the head part of the detection pin is provided with a contact switch, and the contact switch is provided with a red light and a green light and is connected with an electrical control cabinet; and the electrical control cabinet is internally provided with a separate group of memory circuits corresponding to each rivet position, and a result display circuit is also arranged in the electrical control cabinet.

Description

Rivet leaks the riveting pick-up unit

Technical field

The utility model relates to the automatic checkout equipment that uses the rivet product, is specially rivet and leaks the riveting pick-up unit.

Background technology

In daily production; Running into one through regular meeting needs a plurality of rivets of riveted joint above the product, and the operative employee can be leaked the phenomenon of putting rivet unavoidably in practical operation, and the product of producing so just must be done over again again; Production then can strengthen check intensity and production cost for serialization; Even,, might cause serious quality accident when this type substandard product is not having to flow into client under the found situation because check density is not enough.

Summary of the invention

To the problems referred to above, the utility model provides rivet to leak the riveting pick-up unit, can improve and leak riveting check density through control, serialization detection means automatically, the rivet leakage riveting phenomenon when stopping product and on production line, rivet.

Its technical scheme is such: it comprises cushion block, and said cushion block is installed on the bottom of upper bolster and protrudes from the bottom surface of upper bolster, and it is characterized in that: it also comprises test pin; Said test pin is provided with the shaft shoulder; Said shaft shoulder spiral-lock is behind said cushion block, and said test pin afterbody stretches out from said cushion block, and its below is the through hole that ejects that is provided with on the die shoe; Above the said shaft shoulder; Be set with spring on the said test pin, the upper end roof pressure of said spring is in said upper bolster, and the lower end roof pressure of said spring is in the said shaft shoulder; Said test pin above-head is provided with contact switch, and red light, green light are arranged on the said contact switch, said contact switch connecting circuit switch board; Corresponding each riveted joint rivet position is provided with one group of memory circuit separately in the said electric control cabinet, and display circuit as a result is set in the said electric control cabinet.

The utility model adopts after the said structure; During mold work, having under the situation of rivet, rivet withstands test pin; Be set in the length of spring compressed on the test pin; The up contact switch that touches of test pin, green light is bright on the contact switch, and the electrical equipment control that meanwhile links to each other with contact switch cashier's office in a shop result shows that green light is bright; On the contrary, put rivet if leak, when mould presses owing to lack rivet; Test pin can not get the up thrust from rivet, and test pin breaks away from the downward landing of contact switch also owing to the stretching of spring, and the test pin shaft shoulder is limited to cushion block inside; Red light is bright on the contact switch at this moment, owing to add the design of reporting to the police in the circuit, also occurs alerting signal when red light is bright; Equally electrical equipment control cashier's office in a shop the result show that red light is bright, operating personnel show according to the result of electric control cabinet can find riveting position in time, exactly with Louing, and in the electric control cabinet corresponding each rivet rivet position one group of memory circuit be set separately; When being convenient to the subsequent conditioning circuit maintenance like this; As long as find that where organizing the auxiliary reclay pilot lamp does not work, just can know rapidly that where organizing circuit is out of order, need not investigation.

Embodiment

See Fig. 1, Fig. 3, it comprises cushion block 2 the utility model, and cushion block 2 is installed on the bottom of upper bolster 1 and protrudes from the bottom surface of upper bolster 1; It also comprises test pin 3, and test pin 3 is provided with the shaft shoulder 4, and the shaft shoulder 4 spiral-locks are behind cushion block 2; Test pin 3 afterbodys stretch out from cushion block 2, and above the shaft shoulder 4, test pin 3 is set with spring 5; The upper end roof pressure of spring 5 is in upper bolster 1, and the lower end roof pressure of spring 5 is in the shaft shoulder 4, and test pin 3 above-head are provided with contact switch 6; Red light, green light are arranged on the contact switch 6; Contact switch 6 connecting circuit switch boards 7, corresponding each riveted joint rivet position is provided with one group of memory circuit separately in the electric control cabinet 7, and display circuit as a result is set in the electric control cabinet 7.Among Fig. 1, on die shoe 8, set gradually lower cushion block 9, jacking block 10, be provided with the hole 11 of connection between jacking block 10 and the lower cushion block 9; Hole 11 is opened on the bottom surface of lower cushion block 9, and the cecum in hole 11 is positioned at jacking block 10 inside, and spring 12 is installed in the hole 11; The below of corresponding test pin 3; In lower cushion block 9, jacking block 10, die shoe 8, be provided with and eject through hole 13, movable push rod 14 passes and ejects through hole 13 and spiral-lock in die shoe 8, in the outer cover of movable push rod 14 riveted joint cover 15 is housed; The bottom spiral-lock of riveted joint cover 15 is in the bottom surface of lower cushion block 9; The upper end of riveted joint cover 15 is concordant with the upper surface of jacking block 10, and movable push rod 14 connects cylinder (cylinder does not provide in the drawings), and 16 is rivet among the figure.

Below in conjunction with the course of work that illustrates the utility model:

(see figure 1) when product is riveted, product place between cushion block 2 and the jacking block 10, and rivet 16 places movable push rod 14 upper ends; Mold work, cushion block 2 are with the upper bolster 1 descending jacking block 10 of exerting pressure, simultaneously under the bounce effect of spring 12; Movable push rod 14 acts on rivet 16 makes rivet 16 up, and movable push rod 14 contacts rivet 16 all the time, the rivet 16 up test pins 3 that withstand; Cause spring 5 compressions; Test pin 3 continues the up contact switch 6 that touches, and green light is bright on the contact switch 6, meanwhile with electric control cabinet 7 that contact switch 6 links to each other on the result show that green light is bright; On the contrary, put the rivet (see figure 2) if leak in movable push rod 14 upper ends, when mould presses owing to lack rivet; Test pin 3 can not get the up thrust from rivet, and test pin 3 breaks away from contact switch 6 downward landings, and because the stretching of spring 5; The shaft shoulder 4 of test pin 3 is limited to cushion block 2 inside; Red light is bright on the contact switch 6 at this moment, owing to add the design of reporting to the police in the circuit, also occurs alerting signal when red light is bright; The result shows that red light is bright on electric control cabinet 7 equally, and operating personnel can find Lou riveting position in time, exactly according to result's demonstration of electric control cabinet 7; And corresponding each riveted joint rivet position is provided with (see figure 3)s such as one group of memory circuit K1, K2, K3, K4, K5 separately in the electric control cabinet 7; When being convenient to the subsequent conditioning circuit maintenance like this; As long as find that where organizing the auxiliary reclay pilot lamp does not work; Just can know rapidly that where organizing circuit is out of order, need not investigation.
