The utility model also provides a punch press. Through the utility model discloses, can improve upper and lower workstation centering precision.
Description
Technical field
The utility model relates to technical field of mechanical equipment, in particular to a kind of lower work platform centralising device and a kind of punch press of punch press.
Background technology
Punch press comprises upper and lower two workbench, carries out processing operation by driving pumping of upper table.Such as publication number is that in the patent application " a kind of closed type portal high-speed punch press stand " of CN101733965A, workbench is tightly arranged on the body of punch press by securing members such as screws.But because the securing members such as screw itself exist assemblage gap, so workbench installation accuracy is in the horizontal direction difficult to ensure.If the centering of upper and lower workbench cannot ensure, the quality that will reduce the product processed even produces substandard products, waste product.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of lower work platform centralising device that can improve the punch press of upper and lower workbench accuracy of alignment.Another technical problem to be solved in the utility model is, provides a kind of punch press that can improve upper and lower workbench accuracy of alignment.
Therefore, the utility model provides a kind of lower work platform centralising device of punch press, comprise upper table, lower table and at least one alignment pin, all with each described alignment pin on described upper table be correspondingly provided with centring hole on, all with each described alignment pin on described lower table be correspondingly provided with centring hole, described alignment pin and described lower table be vertical to be arranged and its two ends are each passed through corresponding described upper centring hole and described lower centring hole.
In this technical scheme, centering is carried out by the upper centring hole of alignment pin cooperation correspondence, lower centring hole, alignment pin two ends are each passed through centring hole and lower centring hole, when upper table in the course of the work alignment pin can realize the guiding to upper table, ensure the precise alignment of upper table and lower table, avoid, because upper table and lower table accuracy of alignment cause the reduction of product quality not, effectively to improve product quality.
Preferably, the outer wall of described alignment pin is processed with a support level, after described lower centring hole is stretched in the lower end of described alignment pin, described support level is supported on the upper surface of described lower table.In this technical scheme, only utilize support level to support alignment pin, and do not need extra fixing, easy for installation, structure is simple.
Further, described support level is ring-shaped step.In this technical scheme, adopt ring-shaped step support effect better, alignment pin is installed more firm.
Preferably, the described alignment pin length stretched in described lower centring hole is less than the degree of depth of described lower centring hole.In this technical scheme, lower centring hole is not stretched out in the lower end of alignment pin, and the housing construction avoiding lower end to stretch out below to lower table causes interference, can be simpler.
Preferably, described lower table is processed with multiple lower centring hole, multiple described lower centring hole is evenly arranged on described lower table.In this technical scheme, adopt and overlap alignment pin, upper centring hole and lower centring hole more, centering effect can be ensured better for a set of, improve product quality further.
The utility model additionally provides a kind of punch press, comprises the lower work platform centralising device of the punch press according to any one of technique scheme.
In sum, the utility model crosses upper centring hole corresponding to alignment pin cooperation, lower centring hole carries out centering, alignment pin two ends are each passed through centring hole and lower centring hole, when upper table in the course of the work alignment pin can realize the guiding to upper table, ensure the precise alignment of upper table and lower table, avoid, because upper table and lower table accuracy of alignment cause the reduction of product quality not, effectively to improve product quality; Can also only utilize support level to support alignment pin, and not need extra fixing, easy for installation, structure be simple.
Accompanying drawing explanation
Fig. 1 is the structural representation of the lower work platform centralising device of punch press according to the utility model embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
As shown in Figure 1, according to the lower work platform centralising device of the punch press of embodiment of the present utility model, comprise upper table, lower table and at least one alignment pin, all with each described alignment pin on described upper table be correspondingly provided with centring hole on, all with each described alignment pin on described lower table be correspondingly provided with centring hole, described alignment pin and described lower table be vertical to be arranged and its two ends are each passed through corresponding described upper centring hole and described lower centring hole.
In this technical scheme, centering is carried out by the upper centring hole of alignment pin cooperation correspondence, lower centring hole, alignment pin two ends are each passed through centring hole and lower centring hole, when upper table in the course of the work alignment pin can realize the guiding to upper table, ensure the precise alignment of upper table and lower table, avoid, because upper table and lower table accuracy of alignment cause the reduction of product quality not, effectively to improve product quality.
Wherein, alignment pin can be fixedly connected with lower table in lower end, or is connected with the body of punch press through lower table, also can not be fixed.
Preferably, the outer wall of described alignment pin is processed with a support level, after described lower centring hole is stretched in the lower end of described alignment pin, described support level is supported on the upper surface of described lower table.In this technical scheme, only utilize support level to support alignment pin, and do not need extra fixing, easy for installation, structure is simple.
Further, described support level is ring-shaped step.In this technical scheme, adopt ring-shaped step support effect better, alignment pin is installed more firm.
Preferably, the described alignment pin length stretched in described lower centring hole is less than the degree of depth of described lower centring hole.In this technical scheme, lower centring hole is not stretched out in the lower end of alignment pin, and the housing construction avoiding lower end to stretch out below to lower table causes interference, can be simpler.
Preferably, described lower table is processed with multiple lower centring hole, multiple described lower centring hole is evenly arranged on described lower table.In this technical scheme, adopt and overlap alignment pin, upper centring hole and lower centring hole more, centering effect can be ensured better for a set of, improve product quality further.
The utility model additionally provides a kind of punch press, comprises the lower work platform centralising device of the punch press according to any one of technique scheme.
In sum, the utility model crosses upper centring hole corresponding to alignment pin cooperation, lower centring hole carries out centering, alignment pin two ends are each passed through centring hole and lower centring hole, when upper table in the course of the work alignment pin can realize the guiding to upper table, ensure the precise alignment of upper table and lower table, avoid, because upper table and lower table accuracy of alignment cause the reduction of product quality not, effectively to improve product quality; Can also only utilize support level to support alignment pin, and not need extra fixing, easy for installation, structure be simple.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but this embodiment is all included within scope of the present utility model.
