Description

TECHNICAL FIELD

[0001] The utility model relates to the field of shoes machine, especially involves a vamp stop constant polishing device. BACKGROUND

[0002] In the processing of leather shoes (such as cowhide), the stop of the vamp refers to the peripheral wall of the lower end of the vamp (especially the bending end face, so it has curvature), and the stop needs to be bonded with the inner peripheral wall of the sole by glue, so it needs to have a predetermined rough surface to ensure the stability of the bonding.

[0003] However, the existing polishing device has the following problems:

[0004] 1. The polishing precision is inconsistent, mainly due to the uneven polishing force, so the stop may be over-polished (which can easily penetrate) or under-polished (which can easily result in poor adhesion);

[0005] 2. The overall volume is large, which is not suitable for installation of multi-axis mechanical arm;

[0006] 3. The position force control precision of the curvature is poor.

[0007] For example, Chinese invention patent CN202010682157.2 mainly realizes flexible polishing through an elastic member, but the polishing feed stroke cannot be constant (mainly controlled passively by the elastic member, which can easily cause over-polishing), and it is mainly achieved by polishing fit. In actual processing, there is still a problem of over-polishing. INVENTION CONTENTS

[0008] The main purpose of the utility model is to provide a vamp stop constant polishing device, which aims to improve the existing polishing device, ensure the constant polishing force, and thus ensure precise polishing, while the overall volume is relatively compact, facilitating installation in different scenarios.

[0009] To achieve the above purpose, the utility model provides a vamp stop constant polishing device, comprising:

[0010] A rack;

[0011] A moving device, the driving end of the moving device is provided with a first pivot seat, the first pivot seat is provided with a transmission rod arranged in rotation, and the moving device is used to drive the first pivot seat to move horizontally;

[0012] A rotating device, the rotating device is fixedly arranged on the rack, the rack is provided with a second pivot seat, the second pivot seat is provided with a driving shaft, the upper end of the driving shaft is connected with the upper end of the driving shaft, and the lower end of the driving shaft is connected with the upper end of the first pivot seat through a universal shaft and can drive the rotation thereof;

[0013] The mobile device is provided with a control device for receiving the pressure of the lower end of the transmission rod during processing and controlling the relative position of the transmission rod.

[0014] In actual design, the rotation and relative position of the transmission rod are controlled through the universal shaft and the mobile device, so that the rotation of the transmission rod can be effectively ensured while the polishing pressure is controlled, the polishing force on the vamp cuff is ensured, and precise polishing is realized.

[0015] Meanwhile, the mobile device can also control the inclination of the first pivot seat, so that the polishing of the arc surface is realized. BRIEF DESCRIPTION OF DRAWINGS
