Automatic multi-function shoe last special fixture

The present invention relates to an automatic multi-purpose shoe lasting fixture, and more particularly to a shoe lasting fixture technology that can stably grip a shoe last within a tolerance range.

Press, the shoe last is mainly a shoe mold for determining the size of the shoe; in other words, the shoe last is not only the mother of the shoe, but also the molding die of the shoe. The shoe last determines not only the shape and style of the shoe, but also the key to whether the shoe fits the foot. Therefore, the design of the shoe last must be based on the user's foot shape and size, in order to meet the actual size requirements of the foot. Fit shoes. Moreover, with the development of science and technology and the rise of personalized consumption awareness, these factors will make the future shoe production develop towards a small number of diverse production. Therefore, the traditional way of producing shoes by manual or mechanical processing is bound to be impossible. Meet the production needs of today's footwear products. Based on the trend of future footwear, it will be oriented towards a small number of diverse production. Therefore, how to develop an automatic machining control shoe manufacturing equipment that uses automated robotic arms to grasp shoe lasts for multi-process sites has become a related art field. Technical issues that are urgently needed to solve and challenge.

In order to solve the above-mentioned deficiencies, the related art has developed a shoe-making production device for automatic control of the robot arm for shoe production. Although the prior art has the automatic processing and control shoe-making function of the multi-process site, The function of the guide bevel and the guide bevel is not matched with the two clamps, so that the two clamps cannot grasp the shoe last in the tolerance range when the shoe last holder is gripped, so that the shoe last cannot be grasped Smoothly transport the last to the next Not only that, the shoe last of the prior art has no function of fixing the slot, so that the two clips cannot effectively grip the shoe last, so that the shoe last is easy to occur during the transport of the shoe last. The falling situation, thus causing inconvenience and great troubles in the delivery of the shoe last.

In view of the lack of the above-mentioned conventional technology due to the process of gripping the shoe last and conveying, the present inventors actively research and develop, and after continuous trial and experiment, finally develop the results of the novel.

The technical means for achieving the second purpose include a shoe last holder and a jig. The shoe last fixing seat is used for fixing the last, and the outer peripheral ring has four guiding bevels. The fixture comprises two clamping blocks, each clamping block is provided with a tapered inclined groove and a guiding inclined surface located at two opposite sides of the inclined inclined groove, When the clamping block is connected to the driving device, when the driving device drives the two clamping blocks relatively close to the shoe last fixing seat, the guiding inclined faces of the two clamping blocks respectively abut against the guiding oblique sides of the four corners of the last fixing seat. Wherein, the two sides of the shoe last fixing seat are provided with a fixing groove extending from top to bottom, and the fixing groove is used for clamping and fixing with the working platform, so that the shoe last is smoothly transmitted to the next workstation on the working platform.

The third object of the present invention is to provide an automatic multi-purpose shoe lasting fixture with accurate and rapid positioning function, which is mainly configured to quickly position the shoe last fixing seat and the working platform, and when the shoe last is finished, When you want to put it back on the work platform, the shoe last seat with the last is quickly placed on the work platform through a precise positioning structure. The technical means for achieving the third purpose include a shoe last holder and a jig. The shoe last fixing seat is used for fixing the last, and the outer peripheral ring has four guiding bevels. The clamp comprises two clamping blocks, each clamping block is provided with a tapered inclined groove and a guiding inclined surface on two opposite sides of the inclined inclined groove, and the two clamping blocks are connected with the driving device, and when the driving device drives the two clamping blocks relatively close to the shoe last fixing seat, Then, the guiding slopes of the two clamping blocks respectively abut the guiding oblique sides of the four corners of the last fixing seat. The top surface of the last fixing seat is provided with at least one positioning cone hole, and the working platform is provided with at least two protruding cone members for inserting the at least two positioning cone holes.
