Description
Technical field
The present invention relates to one widely used clamping on lathe, plastic molding press, die casting machine, hydraulic press and punch press solid
Determine device, especially relate to a kind of electricity permanent magnetic adsorption-type clamping and fixing device.
Background technology
Along with the development of global industry, lathe, die casting and plastic industry have obtained vigorous growth, the development band of industry
Moved industry innovation and innovation, it is intended to improve efficiency and reduce production cost, for machine industry, workpiece quickly position dress
Folder；For die casting and plastic industry, on the forming machine of the Fast Installation location of mould, become the two industry and improve production
A crucial part for efficiency.
The installation location of processing workpiece and mould is divided into two ways at present, and one is traditional clamped-in style clamping and fixing device；
Two is electricity permanent magnetic adsorption-type clamping and fixing device.
Traditional clamped-in style clamping and fixing device mainly has manual positioning pressuring plate, semi-automatic hydraulic fixture and full-automatic gas hydrodynamic
Pressure fixture, but there is certain defect in these workpiece or mould clamping and fixing device.Specific as follows:
1, manual positioning pressuring plate: needing by manual operations, labor intensity is big, and processing safety is the highest, reliable clamping
Property poor, need periodically fastening；
2, semi-automatic hydraulic fixture: by hydraulic pressure and control realization Automatic-clamping, clamping force is stable, not with external power source
Or the change of pressure and change, however it is necessary that the size according to workpiece manually adjusts chucking position, can be only installed at level
Work surface and the horizontal direction of vertical work surface, owing to installation direction is fixed, and the size of workpiece or mould is because of fixture peace
Dress position and be restricted；
3, Full automatic penumatic hydraulically operated fixture: mode of operation and principle are with semi-automatic hydraulic fixture, and position is with the position of workpiece
Adjust and use automated manner.The shortcoming equally with semi-automatic hydraulic fixture.
Existing electricity permanent magnetic adsorption-type clamping and fixing device is as it is shown in figure 1, the mould of top and the workpiece 1 magnetic by lower section
The magnetic force that plate 2 produces implements absorption clamping.Having reliability high, be difficult to produce with workpiece size interfere, versatility is with suitable
Strong by property.But this kind of electric permanent magnetic adsorption-type clamping and fixing device is to add one piece of base with magnetic function on equipment
Plate, the thickness that Magnetic Substrate is certain because performance requirement has, and change with the change of instrument size.Therefore it is main
Defect is the performance parameter that can affect equipment.Such as: on plastic-injection moulding machine, this application can affect the appearance of equipment
Modulus, needs the parameter by change equipment to meet mould demand client's mold thickness is bigger when, adds
The purchase cost of equipment.The equipment bearing capacity to mould can be reduced, because the weight of Magnetic Substrate itself consumes simultaneously
The mould weight capacity of equipment.Other die-cast formation equipment is similar with plastic molding equipment.And apply on machine industry
Equally can be because of the thickness effect workpiece of Magnetic Substrate or the molar amount of mould (such as punch press industry).
Summary of the invention
The technical problem to be solved is to provide and a kind of does not interferes with the performance parameter of equipment, will not increase equipment
Purchase cost, can improve the electric permanent magnetic adsorption-type clamping and fixing device of device load-bearing capability simultaneously.
The present invention solves the technical scheme that above-mentioned technical problem used: a kind of electricity permanent magnetic adsorption-type clamping and fixing device,
Including pedestal and the magnetic sheet of parent equipment, the surface configuration of described pedestal has cavity, described magnetic sheet to be embedded in institute
In the cavity stated, described pedestal is provided with the cavity described in connection and the through wires hole outside described pedestal.
The surface of described pedestal can be provided with the cavity of two or more independence, and described magnetic sheet is two or more, right
Should be embedded in described cavity.
Described cavity is preferably four, and these four cavitys are arranged on the surface of described pedestal symmetrically.
The degree of depth of the cavity that the thickness of described magnetic sheet is the most described.
Described parent equipment can be lathe or molding machine or die casting machine.
Compared with prior art, the method have the characteristics that magnetic sheet is built-in in the cavity of base-plates surface, therefore have
Advantages below:
1) integrated degree is higher, and integrated performance is relatively good；
2) raw materials consumption of parent equipment (injection moulding machine, lathe, die casting machine etc.) can be reduced；
3) the technology properties parameter of parent equipment is not interfered with, such as the molar amount of equipment, the mould of equipment and workpiece
Supporting power；
4) what the thickness of this kind of modal magnetic plate can compare that the magnetic sheet of tradition external does is thinner, and dependent magnetic plate
Relevant interface can be integrated on the pedestal of parent equipment with the structure of bonding apparatus, install more succinct.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing electricity permanent magnetic adsorption-type frock clamp；
Fig. 2 is the structural representation of the embodiment of the present invention one；
Fig. 3 is the perspective view after the decomposition of the embodiment of the present invention one.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Embodiment: a kind of electric permanent magnetic adsorption-type clamping and fixing device used on injection moulding machine, including injection moulding machine
Pedestal 1 and four pieces of magnetic sheets 2, the surface configuration of pedestal 1 has four independent cavitys 3, and four pieces of magnetic sheets 2 are corresponding
Being embedded in four independent cavitys 3, the thickness of magnetic sheet 2, equal to the degree of depth of cavity 3, pedestal 1 is provided with respectively
Connect the bottom of four independent cavitys 3 and the through wires hole 4 outside pedestal 1.
Had in embodiment by wired meta-analysis means relative analysis and have the pedestal of four cavitys and traditional base without cavity
The stress of seat and deformation.Its analysis result is as shown in the table.
As can be seen from the table, after being provided with four cavitys on original pedestal, either maximum principal stress and tension,
Large deformation and normal direction maximum distortion, all in tolerance range, can meet the design requirement of actual condition completely.And from table
It can be seen that the pedestal of the present invention is owing to embedded in magnetic sheet, the material of magnetic sheet and the base material of parent equipment exist
Difference, the former is better than the latter, so after magnetic sheet loads the pedestal of parent equipment, comparing the material before parent equipment,
Adjust as whole part and can increase the intensity of this part, it is also possible to lifting means is for mould, the bearing capacity of workpiece.
In the above embodiments, injection moulding machine can also be lathe or die casting machine substitutes.
