Description

Technical Field

[0001] The invention relates to the technical field of plunger ring processing, in particular to an automatic grooving and end face dotting device for a plunger ring. Background Art

[0002] The plunger ring is an elastic open ring, which has the functions of sealing on one hand and scraping off the excess oil on the cylinder wall on the other. In order to be installed in the plunger, the plunger ring often needs to be cracked so that the plunger ring has an opening. The existing processing method for this opening is to open a V-shaped groove on the inner circle of the plunger ring and crack the plunger ring by applying pressure to the V-shaped groove. The existing method of opening the V-shaped groove is to complete it by extrusion with a punch and a blade, and the force and punching time of the punch are controlled manually. Therefore, the size, position and depth of the processed V-shaped groove are inconsistent, resulting in inconsistent uniformity of the opening size and cracking direction during cracking. The large opening and the non-straight cracking direction can only be scrapped, and the qualified rate is low. On the other hand, the outer circle of the plunger ring is an arc surface, and the highest point of the arc diameter is not in the center position. In order to prevent the highest point side from being installed in the correct position during installation, it is necessary to mark the end face to identify the highest point side.

[0003] The current processing procedure is divided into two steps: first, the V-groove is opened, and then the dot is made on the end face. Both are done manually, with low efficiency and qualified rate; the grooving process is manually operated on the punch press, which has safety hazards; each dot (point) needs to find the position, which has a certain damage to the workers' eyesight; the grooving process is manually operated on the punch press, and the size, position and depth of the grooves are inconsistent; if the groove is too deep, it is easy to be squeezed and broken when processing the outer circle; if the groove is too shallow, the plunger ring cannot be cracked; the dot is found by the eyes, and the position and angle of each dot are not accurate; grooving and dot are manually loaded and unloaded, with extremely low efficiency; and the dot is manually applied with pressure, and the dot depth cannot be controlled.

A dotting tool 13 is fixedly installed on the bottom of the connecting plate 12. A discharge plate 14 is installed at the bottom of the inner wall of the cabinet 1 and at one end away from the first conveyor belt 3, and a scale rod 15 is installed on one side of the inner wall of the cabinet 1 and on one side of the connecting plate 12.

[0029] Among them, the cabinet 1 is also provided with a counter inside, and is connected to the electric control box 17. The machine can automatically count when it runs automatically. The electric control box 17 is also equipped with an alarm. When the machine fails, lacks material or is stuck, the electric control box 17 will automatically alarm.

[0030] Furthermore, a feeding inclined plate is installed at one end of the vibrating material tray 2 close to the cabinet 1 , and the end of the feeding inclined plate extends to the top end of the first conveyor belt 3 after passing through the feed port.

[0031] A material guide inclined plate is provided at the top of the first conveyor belt 3 and at one end away from the feeding inclined plate, so as to guide the material to slide to the top of the positioning assembly 6 .

[0032] Furthermore, the positioning assembly 6 includes a loading plate 61, the loading plate 61 is slidably installed on the top of the second linear motor 5, a third linear motor 62 is fixedly connected to one side of the loading plate 61, a first clamping plate 63 and a second clamping plate 64 are slidably installed on the top of the third linear motor 62, the first clamping plate 63 and the second clamping plate 64 are coaxially connected, and a rotating cylinder 66 is also slidably installed on the top of the third linear motor 62, the output end of the rotating cylinder 66 is fixedly connected to the rotating shaft of the first clamping plate 63 and the second clamping plate 64, and a second conveyor belt 65 is also installed on the outer side of the loading plate 61 and at one end close to the third linear motor 62.

[0033] When the workpiece is transported to the positioning assembly 6 via the first conveyor belt 3, the workpiece is guided to move onto the loading plate 61 via the guide ramp, and then the workpiece is driven to move between the first clamping plate 63 and the second clamping plate 64 via the second conveyor belt 65, and then the rotating cylinder 66 rotates the first clamping plate 63 and the second clamping plate 64 to clamp the workpiece, and then the workpiece can be driven to move by the first linear motor 4, the second linear motor 5 or the third linear motor 62.

[0034] The loading plate 61 and the discharging plate 14 are located in the same horizontal plane.

[0035] Furthermore, the size of the second clamping plate 64 is larger than that of the first clamping plate 63, a gap is left between the first clamping plate 63 and the second clamping plate 64, and a semicircular groove is provided at one end of the first clamping plate 63 and the second clamping plate 64 away from the third linear motor 62, so as to better clamp and fix the arc-shaped outer edge of the plunger ring.

[0036] Furthermore, the output shaft of the stepper motor 9 passes through the mounting plate 8 and is connected to the groove drawing tool 10 via a universal coupling. The groove drawing tool 10 forms an angle of ninety degrees with the output shaft of the stepper motor 9, so as to better draw grooves on the inner side of the plunger ring.

[0037] Furthermore, the cross-sectional view of the dotting tool 13 is a triangular structure, which facilitates punching a triangular groove on the plunger ring.

[0038] Furthermore, the outer side of the scale rod 15 is threadedly connected to a collar, and the outer side of the collar is rotatably connected to a baffle 16, which is used to limit the connecting plate 12, so as to cooperate with the scale rod 15 to limit the stroke of the piston rod of the thrust cylinder 11.

[0039] Furthermore, one end of the discharge plate 14 extends to the outside of the discharge port of the cabinet 1 .

[0040] Furthermore, an electrical control box 17 is provided on the top of the cabinet 1, and the electrical control box 17 is electrically connected to the vibrating material tray 2, the first conveyor belt 3, the first linear motor 4, the second linear motor 5, the third linear motor 62, the rotating cylinder 66, the fourth linear motor 7, the stepping motor 9 and the propulsion cylinder 11 respectively.

[0041] Specifically, when in use, the vibrating material tray 2 and the first conveyor belt 3 are first used to automatically send the workpiece to the positioning assembly 6, and then the first clamping plate 63 and the second clamping plate 64 are rotated by the rotating cylinder 66 to clamp the workpiece, and the first linear motor 4 and the third linear motor 62 are used to send the workpiece to the bottom of the stepper motor 9, and the stepper motor 9 drives the groove drawing tool 10 to rotate to draw a groove of a certain depth on the workpiece, and then the first linear motor 4 and the second linear motor 5 are used to transport the positioning assembly 6 and the workpiece to the bottom of the propulsion cylinder 11 for dotting. Since the dotting has a specified angle according to the requirements, the first clamping plate 63 and the second clamping plate 64 must be used to clamp the workpiece during the transportation process to prevent the workpiece from rotating during the transportation process. When the workpiece reaches the propulsion cylinder 11, the first clamping plate 63 and the second clamping plate 64 must be used to clamp the workpiece to prevent the workpiece from rotating during the transportation process. After the dotting station is reached below the cylinder 11, the dotting propulsion cylinder 11 will push the dotting tool 13 to dot the surface of the workpiece. The depth of the dotting can be adjusted and controlled according to the baffle 16 on the outside of the scale rod 15. After the dotting is completed, the first linear motor 4, the second linear motor 5 and the second conveyor belt 65 on the positioning assembly 6 push the workpiece to the top of the discharge plate 14, and then return to its original position to prepare for the next workpiece to be transported and processed. The machine can automatically count when it is running automatically, and will automatically alarm when the machine fails, is out of material or is stuck. The above processes are all implemented through program controller programming. The fully automatic program can enable one staff member to operate multiple machines at the same time, freeing up labor. Since it is automatically controlled, safe production is guaranteed.

[0042] In this embodiment, all mechanisms of the present invention are fully automatic. Electrical, pneumatic and mechanical devices are used to complete workpiece loading, grooving, transportation, dotting and other processes. Labor costs can be reduced by completing two processes on one machine. Loading with a vibrating tray 2 can reduce labor. The processing process is controlled separately by a program, and each workstation completes two processing processes at the same time.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
