The technical problems to be solved by the invention are：A kind of product inner side edge clamping device is provided, it is convenient for mounting and clamping, in saving
The blanking time, Surface Appearance is protected not to be scratched, and can ensure Surface Appearance uniformity for the treatment of, ensure adding for product
Working medium amount.
In order to solve the above technical problems, the technical scheme is that：A kind of product inner side edge clamping device, including installation
Seat, the front and rear sides of the mounting base are equipped with positioning plate, and the upper surface of the positioning plate is the first positioning surface, the mounting base
The left and right sides be mounted on locating piece, the locating piece has positioning region, and it is fixed that the positioning region includes be obliquely installed second
Plane and the third positioning surface positioned at the second positioning surface front and rear sides；It is slidably fitted in the mounting base by vertical reciprocal
The briquetting of telecontrol equipment driving, the briquetting have the compressed part for pressing the product inner side edge；The vertical reciprocal fortune
Dynamic device connecting power device.
As an improvement the compressed part includes four seal faces being adapted with four inner side edges of the product.
As an improvement the vertical reciprocator includes：
The briquetting is fixedly mounted in pull rod, one end of the pull rod, and the other end of the pull rod is driving end；
For the elastic element resetted to the pull rod.
As a further improvement, the power plant includes rocking handle, and one end of the rocking handle is articulated with by trunnion axis
In the mounting base, the other end is force side；When operating force side, the rocking handle can offset with the driving end of the pull rod
It leans on.
As a further improvement, the mounting base includes board connecting seat and pedestal, the lower end of the board connecting seat
Equipped with connecting flange, upper end is fixedly connected with the pedestal, the board connecting seat also have axially through cavity；The level
Axis is installed in rocking handle fixed seat, and the rocking handle fixed seat is fixedly installed on the board connecting seat, the locating piece installation
In on the pedestal, the rod body part of the pull rod is vertically slidably mounted on the pedestal, and the both ends of the pull rod are stretched
Go out the pedestal, the driving end of the pull rod is located in the cavity.
As a further improvement, the board connecting seat is equipped with vertical spacing hole, and the rocking handle constrains in described perpendicular
Into limit hole, the force side of the rocking handle is located at the outside of the board connecting seat.
As a further improvement, the positioning plate is wholely set with the pedestal.
As a further improvement, the elastic element is spring, and the driving end of the pull rod is equipped with radial flange, described
Spring is set between the pedestal and the radial flange and the spring pocket is on the pull rod.
As an improvement being equipped with regulating mechanism between the mounting base and the locating piece, the regulating mechanism includes：
Vertical guide between the mounting base and the locating piece；
Adjusting slot hole on the locating piece；
Fastener, the fastener pass through the adjusting slot hole and are fixed in the mounting base.
After employing above-mentioned technical proposal, the beneficial effects of the invention are as follows：
Since product inner side edge clamping device devises positioning plate, locating piece, the pressure driven by vertical reciprocator
Block and power plant, thus in feeding, the bottom surface of product is supported by the first positioning surface of positioning plate, then by fixed
The second positioning surface and third positioning surface of position block position the end of product, realize the quick positioning of product, and ensure every
Flake products are all located in identical position, and then vertical reciprocator drives the inner side edge of die pressing product under sliding block, realize production
The compression of product, in above process, due to not having any contact with the appearance of product during product clamping, greatly
The appearance for protecting product, the appearance of product is protected not to be scratched；It, can be primary when carrying out wire drawing when processing to product

Between, Surface Appearance is protected not to be scratched, and ensure that Surface Appearance uniformity for the treatment of, ensure that the processing matter of product
Amount.
Since the compressed part includes four seal faces being adapted with four inner side edges of the product, pass through four pressures
It is tightly clamped in face of product so that product stress is more reasonable, and product is avoided to be damaged when clamping.
Since the vertical reciprocator devises pull rod and elastic element, power plant pushes driving end motion,
Briquetting can be driven to move up and down, under the action of elastic element, pull rod can automatically reset so that vertical reciprocator knot
Structure is simple.
Since the power plant includes rocking handle, one end of the rocking handle is articulated with by trunnion axis in the mounting base,
The other end is force side；When operating force side, the rocking handle can lean with the driving end of the pull rod, in this way using manual
Mode pull rod is driven to move so that it is at low cost.
Since the mounting base includes board connecting seat and pedestal, the lower end of the board connecting seat is equipped with connecting flange,
Connection with board is facilitated by connecting flange；Since the locating piece is installed on the pedestal, the body of rod of the pull rod
Portion is vertically slidably mounted on the pedestal, and the pedestal, the driving end of the pull rod are stretched out in the both ends of the pull rod
In the cavity of board connecting seat so that clamping device arrangement provided by the invention is more reasonable.
Since the board connecting seat is equipped with vertical spacing hole, the rocking handle is constrained in the vertical spacing hole, because
And the upper lift position of rocking handle can be limited by vertical spacing hole, elastic element is prevented to be damaged.
Since the positioning plate and the pedestal are wholely set, the positioning accuracy of product may further ensure that, and can be with
The quantity of parts is reduced, convenient for assembling.
Since the elastic element is spring, thus the pull rod is resetted using spring, be not only simple in structure, and
It is and at low cost；Since the driving end of the pull rod is equipped with radial flange, it can prevent spring from falling by radial flange.
Due to being equipped with regulating mechanism between the mounting base and the locating piece, the regulating mechanism, which devises, vertically leads
Rail adjusts slot hole and fastener, thus loosening fasteners, the upper-lower position of locating piece is adjusted, because the inclination of the second positioning surface is set
It puts, so as to adapt to the clamping demand of the product of different length, improves the versatility of clamping device；Meanwhile unclamp fastening
Part can also unload locating piece, when locating piece is worn or is damaged, be conveniently replaceable, cost wave caused by avoiding integral replacing
Take.
