Description

Technical Field

[0001] The present invention relates to the field of numerical control machining equipment, and particularly to a workbench with a universal sliding seat type follow-up clamping boot and a machining center thereof. Background Art

[0002] Various numerical control machining equipment are widely used in various fields of manufacturing industry. In the industrial site, it is often necessary to clamp and send the materials, blanks or intermediate parts to be machined or assembled to multiple stations and use different tools and special tools to process them in a chain process. For this reason, many types of multi-station special machine tools have been developed by the engineering community and applied to various fields of manufacturing industry.

[0003] At present, such machining centers are mainly used in the electromechanical manufacturing industry. Usually, fixed fixtures or fixtures installed at the end of mechanical fingers or follow-up fixtures on feeding devices are adopted. These fixtures are used to clamp rigid materials or parts with relatively regular geometric shapes such as metals or plastics, and usually do not need to change the clamping method and position when the station is changed. If it is necessary to change the clamping method and position of the parts, usually the parts are temporarily unloaded on the workbench and then re-clamped after repositioning. This method wastes working hours, has low overall efficiency, occupies a large space, and requires a variety of fixtures. Due to the complex fixture design technology and high cost, this method is difficult to be applied to low-value-added mid- and low-end manufacturing industries such as the shoe-making and clothing manufacturing industries. Especially, the main materials and parts encountered in the manufacturing sites of these industries are soft materials and parts such as leather and fabric, which also bring many difficulties to the fixture design. Therefore, it is necessary to design a machining center for clamping parts that can adapt to the clamping of soft materials, has high clamping, placing and repositioning efficiency, good versatility, low cost, and is convenient for use and maintenance for these traditionally manual-based industries.

[0040] The mirror plate 3 is made of a metal flat plate material, the centering indicator 822 is a semiconductor laser, the bearing parts are standard parts or customized parts, the sliding shoe universal wheel 74 is a standard part or a customized part, the shoe stack magnet 41 is made of a permanent magnetic material, and the remaining components are made of metal materials. The parts and components of the controller 15 and the electrical system can be customized by using existing technologies.

[0041] The working process of the embodiment of the present invention is as follows:

[0042] During production operation, only the sheet workpiece template 1000 made of materials such as leather needs to be placed on the conveyor belt 10. With the support of the control system software, first, the workpiece template is collected into the controller 15 through the camera 14 as a processing setting template, and the processing trajectory, action mode, and time sequence of the workpiece at the corresponding stations of each cutting tool are set. Then, the following automated continuous processing process can be started:

[0043] The operator only needs to randomly place the workpiece 1000 on the conveyor belt 10. At the start state of each workpiece processing cycle, the berths (semicircular notches) of the follower boots in the receiving boot stack 4 are all occupied by follower boots, while there is one vacant berth for a follower boot in each of the transfer boot stack 5 and the discharging boot stack 6. When the workpiece 1000 is conveyed into the field of view of the camera 14, the control system software immediately acquires the workpiece image, identifies its shape and orientation, compares it with the pre-set workpiece template data to determine its type and orientation, and calculates the processing trajectory, action mode and timing of the current workpiece according to the processing trajectory, action mode and timing set for the template. Then the automatic processing process starts. During the processing, the manipulator 12 gently presses the workpiece 1000 through the follower palm 8, drags it above a certain follower boot 7 in the receiving boot stack 4, and aligns the follower palm 8 with the opening center of the follower boot 7. Then the pressure applied by the manipulator 12 to the follower palm 8 increases so that the pressure between it and the follower boot 7 can reliably clamp the workpiece 1000 and overcome the magnetic force constraint of the boot stack magnet 41 in the receiving boot stack 4 on the follower boot 7. After that, the follower palm 8 and the follower boot 7 clamp the workpiece 1000 and move with the manipulator 12 to each processing station to process the workpiece with different tools 11. After the processing at each station of the current workpiece is completed, the manipulator 12 drags the workpiece to the discharging boot stack 6 for parking through the follower palm 8 and the follower boot 7. At this position, the manipulator 12 reduces the pressure on the workpiece, and the clamping of the workpiece by the follower boot 7 and the follower palm 8 is released. Then, the processed workpiece is dialed away from the follower boot 7 and falls into the outer discharging port 9 by using a preset action.

[0044] If it is necessary to change the clamping orientation of the workpiece during a processing cycle, the manipulator 12 can clamp the workpiece 1000 through the follower palm 8 and the follower boot 9 in the middle and drag it to the transfer boot stack 5 for parking. At this position, the manipulator 12 raises the follower palm 8 to leave the workpiece on the follower boot 7 staying in the transfer boot stack 5. Then the manipulator 12 raises its height, aligns the follower palm 8 with another follower boot 7 parked in the transfer boot stack 5 and then drops it again. In this way, the clamping orientation of the workpiece can be changed.

[0045] After a workpiece is processed and discharged, under the action of the control system, the manipulator 12 returns the follower palm 8 to the position where the discharging boot stack 6 is located, aligns it with the follower boot 7 staying therein and presses it tightly. Then it drags the follower boot 7 back and resets it to the receiving boot stack 4. Then the manipulator 12 raises its height to make the follower palm 8 disengage from the follower boot 7. After that, it enters the processing cycle of the next workpiece.

[0046] As is known by common technical knowledge, the present invention can be implemented by other embodiments that do not depart from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
