Abstract

The utility model relates to a jaw clamping structure of a front upper machine, which comprises a set of clamping jaws arranged on a machine table and a support table positioned at the central part of the clamping jaws. The set of clamping jaws are all fixedly locked on each corresponding positioning block by fixing bolts; the top end of the support table comprises a table seat, the bottom part of the table seat is connected with a power cylinder which can move up and down, and the tail end of the power cylinder is provided with a contact switch; the contact switch can move to a prearranged position along with the power cylinder and contact with an inductor arranged in the machine table, and the downward motion of the power cylinder is stopped. The utility model is convenient for the disassembly and the replacement of the fixing bolts of the clamping jaws, can effectively shorten the change time of the clamping jaws, decrease the time cost, and effectively enhance the production efficiency.

Description

The lasting pincers clamping jaw structure

The utility model relates to a kind of lasting pincers clamping jaw structure, and is particularly a kind of in the operation of shoemaking process toe lasting, grips the vamp periphery so that the jaw that carries out bonding operation with sole.

In the shoemaking process, the toe lasting operation is meant the vamp of footwear body and this manufacture process of sole bonding.Vamp and sole is bonding in the lasting pincers operation, mainly be to utilize jaw clamping vamp periphery, utilize jaw central authorities to shore shoe tree pushing tow that platform sets firmly again to the location, and make both can be firmly bonding smoothly, wherein at difform footwear body, sharp as the women's shoes toe-cap, Men's Shoes toe-cap broad, or the footwear body of different size specification are as adult shoe and children's shoes etc., because of the footwear shape difference in size opposite sex greatly, in bonding processing operation, must use various jaw, use to adapt to all types of footwear body processing, and the clamping jaw structure of lasting pincers is provided with the platform of shoring of a storing shoe tree in each jaw central authorities, therefore when changing jaw, must pull down shoring platform earlier, smoothly the set bolt of dismounting jaw, carry out the replacing operation of each jaw, after operation to be replaced is finished, will shore platform again and install, the very numerous and diverse inconvenience of this process, quite spended time also can't effectively be boosted productivity.

The purpose of this utility model provides a kind of lasting pincers clamping jaw structure, convenient various types of jaws are changed, can effectively shorten the time of changing the outfit, and then enhance productivity, vamp and sole bonding operation at various dissimilar size footwear bodies, it is required to adapt to its processing to change the jaw kind at any time, does not need the complicated program that changes the outfit

For achieving the above object, the utility model is taked following design: this lasting pincers clamping jaw structure comprises one group of platform of shoring that is installed on the jaw on the board and is positioned at jaw central authorities, this group jaw all is locked on each corresponding locating piece by set bolt, this is shored the platform top and then comprises a pedestal, but the pedestal bottom connects the power cylinder of a upper and lower displacement, the power cylinder end then is provided with a contact-making switch, after this contact beginning can be displaced downwardly to predeterminated position with power cylinder, touch with the inductor of board inside, make power cylinder move down action and stop.

Because the platform of shoring of the present utility model can move up and down, when changing jaw, desire need only descend shoring platform, can make things convenient for the dismounting of the set bolt of each jaw, reach the purpose of changing jaw.

The utility model has the advantages that:

1, but the utility model is shored the design that platform has the rise and fall displacement, makes things convenient for changeing of jaw set bolt, can effectively shorten the replacing time of jaw, significantly reduces time cost, and can effectively enhance productivity.

2, the utility model is shored platform and is had safety device design, and its contact-making switch can make the decline displacement restriction of pedestal in preset range, is unlikely therefore to break away from safe range.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model D structure schematic diagram ()

Fig. 2 is an action schematic diagram of the present utility model ()

Fig. 3 is the utility model D structure schematic diagram (two)

Fig. 4 is the utility model action schematic diagram (two)

As shown in Figure 1 and Figure 2, the utility model mainly comprise one group be installed on the jaw 10 of board A top and be positioned at jaw 10 central authorities shore platform 20, wherein this group jaw 10 all is locked on each corresponding locating piece 12 by set bolt 11, this face is shored platform 20 tops and is then included a pedestal 21, but the pedestal bottom connects the power cylinder 22 of a upper and lower displacement, power cylinder 22 ends also are provided with a contact-making switch 23, after this contact-making switch 23 can be displaced downwardly to predeterminated position with power cylinder 22, touch with the inductor B of board A inside, make power cylinder 22 move down action and stop.

As Fig. 3; shown in Figure 4; the utility model is shored the pedestal 21 of platform 20 can the upper and lower displacement by the action of power cylinder 22; therefore can control the decline and the rising of shoring platform 20 pedestals; when desire is changed jaw 10; the pedestal 21 of shoring platform 20 need only be descended with power cylinder control; the set bolt 11 of jaw 10 is exposed; just staff's demounting bolt 11 is changed jaw 10; and the decline of shoring platform 20 pedestals 21 is risen and can be controlled in the control panel of board A by operating personnel; and spacing design with contact-making switch 23; after power cylinder 22 drops to predeterminated position; can touch with the inductor B of board A inside; the down maneuver of power cylinder 22 is stopped, and effectively platform 20 is shored in protection, makes unlikely displacement detach safe range.

Below only be an embodiment of the present utility model, any based on equivalents of the present utility model all within protection domain of the present utility model.

Claims

1, a kind of lasting pincers clamping jaw structure, it comprises one group of platform of shoring that is installed on the jaw on the board and is positioned at jaw central authorities, it is characterized in that: this group jaw all is locked on each corresponding locating piece by set bolt, this is shored the platform top and then comprises a pedestal, but the pedestal bottom connects the power cylinder of a upper and lower displacement, and the power cylinder end then is provided with a contact-making switch, after this contact beginning can be displaced downwardly to predeterminated position with power cylinder, touch with the inductor of board inside, make power cylinder move down action and stop.
