Abstract

The utility model discloses a switching mechanism of a main positioning pin and an auxiliary positioning pin. The switching mechanism of the main positioning pin and the auxiliary positioning pin is characterized by being providing with a linear motion body, one end of the linear motion body is connected with a linear drive mechanism, and the other end of the linear motion body is externally connected with a positioning pin through a pin hole. The linear drive mechanism is a drive cylinder, the linear motion body is driven by the drive cylinder to make linear motion back and forth between an upper limit position and a lower limit position which are set, and two different positioning points which correspond to the upper limit position and the lower limit position are obtained through the linear motion body. The switching mechanism of the main positioning pin and the auxiliary positioning pin is simple in structure and easy to implement.

Description

Major and minor alignment pin switching mechanism

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 causes easily 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 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 design feature of the major and minor alignment pin switching mechanism of the utility model is: a straight line motion body is set, and an end of described rectilinear motion body connects straight line driving mechanism, and the other end is with the external alignment pin of pin-and-hole; Described straight line driving mechanism is for driving cylinder, between the upper limit position of setting and lower position, come and go rectilinear motion by driving the described rectilinear motion body of air cylinder driven, obtain respectively the anchor point different from corresponding two in described upper limit position and lower position by described 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

Major and minor alignment pin switching mechanism is that a straight line motion body is set in the present embodiment, and an end of rectilinear motion body connects straight line driving mechanism, and the other end is with the external alignment pin of pin-and-hole; Straight line driving mechanism is for driving cylinder, between the upper limit position of setting and lower position, come and go rectilinear motion by driving air cylinder driven rectilinear motion body, obtain respectively the anchor point different from corresponding two in upper limit position and lower position by the rectilinear motion body.

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 1b; 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, by the external alignment pin of 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.
