Abstract

The utility model discloses a single-guide-rod main-auxiliary location pin switching mechanism which is characterized by comprising a base, a driving air cylinder and a guide shaft. The base is formed by a lower bottom plate, an upper limit plate and a back plate, an air cylinder seat of the driving air cylinder is fixedly arranged at the bottom of the lower base plate, an air cylinder extends upwards from a through hole of the bottom plate, the guide shaft serves as a linear motion main body, the bottom end of the guide shaft is connected at the rod end of the air cylinder rod, a location pin hole is positioned at the front end of the guide shaft, the guide shaft extends upwards from a limit through hole of the upper limit plate, and the location pin hole is externally connected with a location pin. The single-guide-rod main-auxiliary location pin switching mechanism uses the driving air cylinder to drive the linear motion main body to do rectilinear motion repeatedly between the set upper limit position and the set lower limit position, and two different location points respectively corresponding to the upper limit position and the lower limit position can be achieved by the linear motion main body.

Description

The major and minor alignment pin switching mechanism of single guide rod

Technical field

The utility model relates to alignment pin switching mechanism on the welding line, more specifically says the switching mechanism between the two alignment pins in the scope of setting.

Background technology

On the weld car line, servomotor commonly used, synchronous motor, roller screw etc. change the position of alignment pin as power at present, although some complete set of equipments are arranged, its cost is high, maintenance cost is high, can not be used widely.On the other hand, in order to improve welding efficiency, the existing mode that adopts swinging cross welding body in white, for this reason, the single guide rod dowel mechanism of fit applications in the swinging cross sealing wire part that also is absolutely necessary; But existing dowel mechanism is take electrical equipments such as motors as actuator, and adopts and to be rigidly connected, and this form structure is complicated, cost is high; And rigidly connected direct switching easily causes the damage of original paper thereby causes unnecessary waste.

Summary of the invention

The utility model is for avoiding the existing weak point of above-mentioned prior art, provide a kind of simple in structure, easy to use, easy to maintenance, major and minor alignment pin switching mechanism of single guide rod cheaply, in order to realize safely and reliably the switching of the major and minor dowel mechanism position of two kinds of different plates.

The utility model technical solution problem adopts following technical scheme:

The major and minor alignment pin switching mechanism of the utility model list guide rod is characterized in that arranging:

One pedestal as supporting member is by lower shoe, upper limit plate with in a side lower shoe is consisted of with the backboard that the upper limit plate is fixedly connected with; Be provided with bottom hole at lower shoe, be provided with limiting through hole at the upper limit plate, described bottom hole and limiting through hole are on the coaxial position;

The one driving cylinder as actuator, its cylinder block is fixedly installed on the bottom of lower shoe; Cylinder rod upwards protrudes out in bottom hole;

One axis of guide as the rectilinear motion body, its bottom is connected to the rod end of cylinder rod, and the axis of guide that front end is provided with dowel hole upwards protrudes out in the limiting through hole of upper limit plate, by the external alignment pin of dowel hole.

The major and minor alignment pin switching mechanism of the utility model list guide rod is characterized in that in the bottom of the described axis of guide one spacing ring being set, and described spacing ring is limited between upper limit plate and the lower shoe.

The major and minor alignment pin switching mechanism of the utility model list guide rod is characterized in that being fixedly installed one from moistening axle sleeve in described limiting through hole, the described axis of guide is that certainly to moisten axle sleeve be guide pin bushing.

The utility model is to come and go rectilinear motion by driving air cylinder driven rectilinear motion body between the upper limit position of setting and lower position, obtains respectively the anchor point different from corresponding two in upper limit position and lower position by the rectilinear motion body.Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model only needs gases at high pressure, need not other power, and is environment friendly and pollution-free;

2, the utility model can guarantee result of use, can significantly reduce again equipment cost, reduce maintenance cost;

3, the utility model is simple, convenient;

4, the utility model driving mechanism can adopt the domestic standard part, and is at the bottom of the cost, easy to implement;

5, the utility model drives cylinder and can be set to the button control mode, makes the steady noiseless of switching between the diverse location support.

The specific embodiment

Referring to Fig. 1 and Fig. 2, arrange in the present embodiment:

One pedestal as supporting member, by lower shoe 1a, upper limit plate 1b with in a side lower shoe 1a is consisted of with the backboard 1c that upper limit plate 1b is fixedly connected with; Be provided with bottom hole 1d at

lower shoe

1a, 1b is provided with limiting through hole 1e at the upper limit plate, and bottom hole 1d and limiting through hole 1e are on the coaxial position.

The one driving cylinder as actuator, its cylinder block 4a is fixedly installed on the bottom of lower shoe 1a; Cylinder rod 4b upwards protrudes out in bottom hole 1d.

One axis of guide 2 as the rectilinear motion body, the bottom of the axis of guide 2 is connected to the rod end of cylinder rod 4b, and the axis of guide 2 that front end is provided with dowel hole 2b upwards protrudes out in the limiting through hole 1e of upper limit plate 1b, is used for external alignment pin by dowel hole 2b.

In the implementation, in the bottom of the axis of guide 2 a spacing ring 2a is set, spacing ring 2a is limited between upper limit plate 1b and the lower shoe 1a.Be fixedly installed one from moistening axle sleeve 3 in limiting through hole 1e, the axis of guide 2 is that certainly to moisten axle sleeve 3 be guide pin bushing, accurately the location.

Figure 3 shows that the positioning states of the axis of guide 2 elongations;

Figure 4 shows that the positioning states that the axis of guide 2 is return.
