First, with reference to fig. 1, a description will be given of the direction definition in the drawings of the present invention. The Z in the attached drawing is to the direction of making progress for piston ring polishing automatic feeding equipment, and under the general condition, equipment is arranged up for vertical direction, consequently the utility model discloses in, the utility model discloses in to Z is to vertical upwards explaining statement. However, it will be appreciated by those skilled in the art that certain manual offset/incidental tolerances of the Z-direction from the vertical are permitted at installation due to environmental or other reasons. For Z to setting up XY plane, because the utility model discloses acquiescence Z is to vertical, then XY plane is the horizontal plane. The default of this application is with material feeding unit 2's direction of delivery as Y axle direction, and on setting, this is the axial of the polishing station of polishing equipment simultaneously, on this basis, establishes right-hand coordinate system, and X axle direction has actually confirmed.

In the following description, when directions and plane ranges are described by coordinate axes or coordinate planes, directions parallel to the corresponding coordinate axes or plane ranges parallel to the corresponding coordinate planes are all referred to unless otherwise specified.

The automatic feeding equipment for polishing the piston ring extends out of the feeding device 2 to two sides along the axial direction of a polishing station of a polishing machine W1, and the feeding device 2 moves a piston ring clamp W on the feeding device into the polishing station from an inlet of the polishing station in the polishing process and then moves the piston ring clamp W out of the polishing station. The transfer device 1 is provided above the feeding device 2 and is movable in the XY plane, and a gripping mechanism 14 for gripping the piston ring jig W is provided at a movable end of a telescopic mechanism 12 provided along the Z direction. The transfer device 1 is not only used for returning the piston ring fixture W subjected to the first polishing from the discharging station 2O of the feeding device 2 to the feeding station 2I to realize multiple polishing, but also used for transferring the piston ring fixture W from the feeding device 3 to the feeding station 2I and transferring the piston ring fixture W from the discharging station 2O to the discharging device 4.

Specifically, fig. 2 is the utility model discloses a feeding device 2's installation schematic diagram, feeding device 2 sets up along polishing station's of burnishing machine W1 direction. Feeding device 2 can be a Y that link up burnishing machine W1 to the overall structure of both sides, nevertheless the utility model discloses a in the embodiment of feeding device 2 in fig. 2, feeding device 2 divide into two structurally independent first feeding device 2A and second feeding device 2B (in the control, both realize the coordination in the chronogenesis through control system or sensor) that set up along Y to both sides at burnishing machine W1. The first feeding device 2A and the second feeding device 2B have substantially the same structural composition, and therefore only one thereof needs to be described. Taking the first feeding device 2A as an example, the first feeding device 2A includes a conveying assembly 21 disposed along the Y direction, which is a conveyor belt or similar conveying device disposed at a position equal to the polishing station along the Y direction, and guide assemblies 22 are respectively arranged along both sides of the conveying surface of the conveying assembly 21 along the X direction at a proper distance, where the proper distance refers to a height at which the guide assemblies 22 contact the piston ring fixture W on the conveying assembly 21, so that the position and orientation of the guide assemblies on the conveying assembly 21 along the X direction do not change, and a freely rotating contact roller is disposed on a surface of the guide assembly 22 contacting the piston ring fixture W to roll along with the advance of the piston ring fixture W, so as to prevent the piston ring from scratching the surface of the fixture W. In general, the guide assemblies 22 on both sides and the lower conveying assembly 21 form an upper open U-shaped cross-sectional area, which is the feed area 2W along which the piston ring holders W enter and exit the polishing station of the polishing machine W1.

Fig. 3 is a schematic top view of the first feeding device 2A, and as an alternative arrangement, the X-position of the guide assembly 22 is adjustable to change the width of the feeding area 2W to meet the polishing requirements of piston ring clamps W of different size series. In this embodiment, the X-direction position adjustment of the guide assembly 22 is realized by an adjusting assembly 24, the adjusting assembly 24 is provided with a screw rod mechanism along the X-direction, and the hand wheel is coaxially fixed with the screw rod. By turning the hand wheel, the lead screw drives the guide assembly 22 to translate in the X direction. The first feeding device 2A is further optionally provided with a material pushing assembly 23 along the direction of the conveying assembly 21, in fig. 3, the material pushing assembly 23 is in a contracted state, and is outside the feeding area 2W, when the piston ring fixture W moves to be about to enter the polishing station, the material pushing assembly 23 extends into the polishing station along the X direction, and then the piston ring fixture W is pushed into the polishing station of the polishing machine W1 along the Y direction.

As shown in fig. 4, the transfer device 1 is above the feeding device 2, and the translation in the XY plane is realized by moving components (a fixed end of another moving component is superposed on a movable end of one group of moving components) which are orthogonally connected in series and arranged on the machine frame. The clamping mechanism 14 is arranged at the telescopic end of the telescopic mechanism 12 which is arranged on the shifting device 1 and downwards along the Z direction, the clamping mechanism 14 is of a clamping structure, and the piston ring fixture W is clamped by two clamping jaws 141 which are arranged oppositely to realize the grabbing and transferring of the piston ring fixture W. Since the transfer device 1 can move in the XY plane and the gripping mechanism 14 can change the working height in the Z direction by the rotating mechanism 13, the transfer device 1 can transfer the piston ring jig W in the equipment space. In order to cooperate the linking of front and back process, the utility model discloses still be provided with loading attachment 3 and unloader 4, then, fixture 14 mainly can realize taking out piston ring anchor clamps W from unloader 4 then remove and put into feeding station 2I after the adjustment gesture, can take out piston ring anchor clamps W from ejection of compact station 2O simultaneously and put into unloader 4 with it.

When the piston ring is polished for multiple times, the polishing direction is important, and whether the polishing amount of the outer circular surface is uniform or not is determined. In the polishing system of traditional manual material loading, control polishing direction is fairly simple, firstly through the clamping direction of artificial change piston ring anchor clamps W in the clamping of a lot of, secondly through the reciprocating motion realization of throwing aureola along Y axle direction. However, in the automatic feeding device for piston ring polishing, since the position of the guide assembly 22 is fixed, there is no space for the polishing wheel to move, and only an additional solution can be found. Move in this application and carry device 1 and can move in XY plane between feed station 2I and ejection of compact station 2O in order to accomplish material loading, unloading operation. For this reason, it is possible to realize multiple polishing of the piston ring jig W by utilizing the moving capability of the transfer device 1, and to realize the change of the polishing direction of the piston ring jig W. Therefore, in the embodiment of the transfer device 1 shown in fig. 5, the telescopic end of the telescopic mechanism 12 is further coaxially provided with a rotating mechanism 13, and the clamping mechanism 14 is provided on the rotating mechanism 13. The rotation mechanism 13 effects rotation of the drive gripper mechanism 14 about the Z axis. When the clamping mechanism 14 takes the polished piston ring fixture W from the discharging station 2O and returns to the feeding station 2I for preparation of polishing for multiple times, the rotating mechanism 13 drives the clamping mechanism 14 to rotate 180 degrees, so that the piston ring fixture W clamped by the clamping mechanism is reversed and then is placed into the feeding station 2I again, and reverse repeated polishing operation is realized.

One embodiment of the rotary mechanism 13 is provided in fig. 5, the rotary mechanism 13 including a drive rack 132 having a rotational axis along the Z-axis direction, wherein the housing surrounding the drive rack 132 is transparently processed in order to show the drive rack 132. The rack drive rack 132 engaged with the drive rack 132 is driven to rotate by the linear drive means to thereby effect rotational control of the drive rack 132 and hence the gripping mechanism 14.

In the embodiment of the present application, the feeding device 3 and the discharging device 4 are both disposed parallel to the X direction, but this is not necessarily the only preferred embodiment for easy arrangement. In principle, both the loading device 3 and the unloading device 4 can be arranged at an angle to the X direction in the XY plane. Because the angle of the clamping mechanism 14 is controllable, the transfer device 1 can move in the XY plane, so that the direction and the specific arrangement of the feeding device 3 and the discharging device 4 can be flexibly arranged as long as the feeding device and the discharging device can be arranged in the working space of the clamping mechanism 14.
