Detailed Description

In order to make the objects and features of the present invention more comprehensible, embodiments of the present invention are further described below with reference to the accompanying drawings, however, the present invention may be implemented in various forms, and should not be limited to the described embodiments. Moreover, without conflict, one of ordinary skill in the art will recognize that the embodiments and features of the embodiments in the present application are susceptible to combination or substitution with one another. The advantages and features of the present invention will become more apparent in conjunction with the following description. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

In the process of shot blasting treatment, the tool full of parts to be treated enters the shot blasting chamber along the track, and is driven by a motor at the top of the shot blasting chamber in the shot blasting chamber, and the tool can rotate for 360 degrees to fully receive shot blasting treatment. However, after the shot blasting is finished, the stop state of the tool is free, namely the rotation angle of the tool when the tool moves out of the shot blasting chamber is variable, and then the rotation angle of the tool when the tool reaches the feeding and discharging station is also variable. Therefore, only manual loading and unloading can be carried out. However, shot blasting often processes tens of hundreds of parts to be processed at a time, and as seen from data common to applicant factories, 250 processed parts need to be manually discharged and 250 parts need to be manually charged within 15 minutes, so that the labor intensity of operators is very high, and the time required for charging and discharging is long.

In order to realize the automatic unloading of going up of robot, the utility model provides an automatic location hangs quick-witted frock of hanging. As shown in fig. 1, the automatic positioning hanging machine tool comprises: the tool comprises a tool body 1, a positioning rotary table 3 and a positioning induction device (a part is omitted in the figure). The location sensing means comprises a sensor 6 and a location mark 8.

The outline of the tool body 1 will be described with reference to the front view and the plan view of an embodiment shown in fig. 1 and 2. The tool body 1 comprises a main shaft, and a hanging ring for fixing a rope or a hook of a hanging machine is further arranged above the main shaft. A plurality of hanging branches 9 extend from the main shaft, and a part (group) 10 to be processed is hung at one end of each hanging branch 9 far away from the main shaft. In order to be able to suspend as many parts to be treated as possible, a plurality of suspension branches 9 are arranged in layers, each layer comprising 4 or 6 suspension branches 9. The angle between 4 or 6 hanging branches 9 of each layer is 90 ° or 60 °, and an embodiment in which each layer includes 6 hanging branches 9 is shown in fig. 2.

The location revolving stage 3 sets up on going up the unloading station, and when frock body 1 was followed the rail displacement and is gone up the unloading station, location revolving stage 3 was located the below of frock body 1, hang the quick-witted cable or couple of loosing of hanging, make frock body 1 place on location revolving stage 3 to when location revolving stage 3 was rotatory, frock body 1 can be followed location revolving stage 3 and rotated. The positioning sensing device can be positioned in the rotating process of the tool body 1, and a preset feeding and discharging initial position is found.

As shown in fig. 1, the sensor 6 may be mounted on the tool body 1, and at this time, the positioning mark 8 may be mounted at a fixed position outside the tool, and the distance and the orientation are limited by the sensing capability of the sensor 6. In this embodiment, the positioning rotary table 3 rotates the tool body 1 until the sensor 6 senses the positioning mark 8 (indicated by the dotted line in the figure), that is, the loading/unloading start position is found. At this time, the positioning rotary table 3 stops rotating, and the feeding and discharging operations can be performed on the portion (or one side) facing the face-up discharging robot. After the part is processed, the positioning rotating platform 3 continues to rotate according to a preset angle, and the loading and unloading robot can carry out loading and unloading operation on the next part of parts. And the loading and unloading operation of all parts can be completed until the positioning rotating table 3 rotates the tool body 1 for a circle according to a preset angle. Taking the tool shown in fig. 2 as an example, when the positioning rotating platform 3 stops rotating for the first time, the sensor 6 senses the positioning mark 8, and then the positioning rotating platform 3 is controlled to rotate 60 ° each time, so that after 5 times of rotation, the parts on the tool body 1 can be completely updated.

In another embodiment, the sensor is disposed on the loading and unloading robot, and the positioning mark is disposed on the tool body 1. It is recommended that the sensor is disposed on a moving axis of the loading and unloading robot, for example, a six-axis robot may dispose the sensor on a sixth axis. Correspondingly, the positioning mark in the present embodiment is recommended to be disposed on the tool main body 1, and specifically, may be disposed at the position of the sensor 6 in the previous embodiment. The working process description of this embodiment may refer to the previous embodiment, which is not repeated herein.

The sensors in both embodiments described above are preferably laser sensors.

Further, as shown in fig. 1, the first layer or the lowest layer of the hanging branches 9 is not always disposed at the end of the main shaft, and therefore, the bottom end of the main shaft is always protruded, which causes a problem that the tool body is not easily and stably disposed on the positioning rotating table 3. Therefore, a recess 11 is provided at the center of the positioning rotary table 3 for accommodating an end of the spindle, so that the tool body 1 can be stably placed on the positioning rotary table 3 without random shaking. In the embodiment shown in fig. 1, the bottom end of the main shaft is inserted into the recess 11, and the tool body 1 can be stably placed on the positioning rotary table 3 and can rotate along with the positioning rotary table 3. Preferably, in order to play a certain guiding role and enable the tool body 1 to be placed at a close position each time, the longitudinal section of the concave part 11 is set to be an inverted trapezoid.

Further, as shown in fig. 1, after the parts to be processed are mounted, since the parts to be processed have heights, if the bottom end of the tool body 1 is directly placed into the recess 11, the parts to be processed may be directly contacted with the table surface of the positioning rotating table 3, which is obviously an undesirable situation in the shot blasting process. Because the parts to be processed are hung on the hanging branches 9 in a hanging manner and are not fixed, when the parts to be processed are in direct contact with the table top, the parts to be processed fall off from the tool body 1. Another possible situation is that when the parts to be processed are not hung, the hanging branch 9 at the lowest layer is directly contacted with the table surface of the positioning rotating table, so that the parts to be processed cannot be hung normally by the hanging branch 9 at the lowest layer. In this embodiment, a supporting base 2 is disposed above the recessed portion 11, and a hole for the spindle to pass through is disposed in the center of the supporting base 2, and the hole is located above the recessed portion 11. When the tool body 1 moves to the loading and unloading station, the bottom end of the main shaft firstly penetrates through the hole and then enters the concave part 11. The thickness of the supporting base 2 can be selected according to the hung part to be processed, and the distance from the bottommost layer hanging branch 9 to the table top of the positioning rotating table 3 is adjusted through the thickness of the supporting base 2, so that the bottommost layer hanging branch 9 can be normally used.

The positioning and rotating table 3 further comprises a servo motor 5 and a synchronization device 5. The servo motor 5 is a power unit for driving the positioning rotary table 3, and has two functions. Firstly, the positioning rotating platform 3 is driven to rotate slowly, so that the sensing device can find and position conveniently; and secondly, after the positioning point is found, the workpiece is rotated for a plurality of times according to a preset angle until the loading and unloading robot finishes loading and unloading work of all parts on one tool. In this embodiment, the synchronizing device 5 adopts a scheme that a synchronous belt is matched with a synchronous pulley.

Further, the utility model also provides a shot-blasting machine. The automatic positioning hanging machine tool is arranged at the feeding and discharging position of the shot blasting machine, so that automatic feeding and discharging are realized. For a common shot blasting machine adopting a Y-shaped track, the automatic positioning hanging machine tool can be arranged at two loading and unloading positions, and continuous shot blasting can be realized.

The automatic positioning hanging machine tool is provided with the sensing device for positioning, automatic feeding and discharging operation is achieved, the problems of heavy labor and low efficiency are solved, and a good solution is provided for large-batch and continuous shot blasting.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
