Description

Technical Field

[0001] The utility model relates to the field of graphite ring assembly equipment, in particular to an automatic material taking and pressing mechanism for sealing graphite rings for pumps. Background Art

[0002] Sealing graphite rings are molded from low-sulfur expanded graphite, with precise dimensions, adjustable density, and no external fillers or adhesives. They have all the characteristics of expanded graphite, can withstand violent alternating temperatures and pressures, and are ideal fillers for valves and various static seals.

[0003] During the assembly and processing of the dynamic ring of the pump body mechanical seal, the graphite ring needs to be pressed into the bellows of the dynamic ring of the pump body. Although the existing graphite ring assembly is automatically pressed by a cylinder, it is still necessary to manually transfer the graphite ring to the pump body before assembly. In addition, the existing graphite ring lacks guidance during assembly and the assembly quality is poor. Therefore, an automatic material taking and pressing mechanism for pump sealing graphite rings is needed. Utility Model Content

[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0014] refer to Figure 1-Figure 2 The shown embodiment is an automatic material taking and pressing mechanism for sealing graphite rings for pumps, comprising a side plate 1, on which a lifting cylinder 2 and a first slide 201 are provided, and the upper and lower sides of the first slide 201 are respectively fixedly connected with a pressing cylinder 3 and a clamping cylinder 4, and the two clamping seats of the clamping cylinder 4 are fixedly connected with C-shaped chucks 401, and the clamping cylinder 401 is used to drive the two C-shaped chucks 401 to take graphite rings, and the piston rod of the pressing cylinder 3 is fixedly connected with a second slide 301, and the second slide 301 is fixedly connected with a pressing head 302, and the pressing head 302 is located between the two C-shaped chucks 401.

[0015] The side panel 1 is fixedly connected with a first slide rail 5, and the first slide seat 201 is slidably connected to the first slide rail 5. The first slide rail 5 can guide the sliding of the first slide seat 201 to prevent the first slide seat 201 from shifting during the sliding process. The lifting cylinder 2 is fixedly connected to the side panel 1.

[0016] The first slide seat 201 is fixedly connected with a second slide rail 6 , and the second slide seat 301 is slidably connected to the second slide rail 6 . The second slide rail 6 can guide the sliding of the second slide seat 301 to prevent the second slide seat 301 from deviating during the sliding process.

[0017] The second slide seat 301 is located between the pressing cylinder 3 and the clamping cylinder 4. Each of the C-shaped chucks 401 is provided with an arc groove. The C-shaped chuck 4 can guide the pressing of the graphite ring to improve the processing quality.

[0018] The working principle of the utility model is as follows: when the utility model is in use, the graphite ring and the pump body are fed by an external feeding mechanism, and when the graphite ring is fed to the bottom of the C-shaped chuck 401, the lifting cylinder 2 drives the first slide 201 to slide down, and the clamping claw cylinder 4 drives the C-shaped chuck 401 to clamp the graphite ring, and then the piston rod of the lifting cylinder 2 is retracted, and the graphite ring also rises accordingly, and then when the pump body is transported to the bottom of the pressure head 301, the piston rod of the lifting cylinder 2 is extended again to make the graphite ring abut against the corresponding assembly position of the pump body, and then the piston rod of the pressing cylinder 3 is extended, and the pressure head 302 presses the graphite ring down to make it completely pressed into the corresponding position of the pump body, and then the piston rod of the pressing cylinder 3 is retracted, the clamping claw cylinder 4 is released, and the lifting cylinder 2 returns to its original position, thereby completing the assembly processing of the graphite ring.

[0019] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific implementations. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
