Description
Technical Field
[0001] The utility model relates to the technical field of closer manufacturing, and particularly to an equipment for pressing rubber rings on a closer housing. Background Technique
[0002] A closer is a hydraulic automatic door-closing device that drives the door leaf to close through an internal spring and a hydraulic system. Its core principle is to use a gear to drive a rack plunger to compress the spring, and the hydraulic oil forms a buffer through a throttle valve to achieve adjustable closing speed. Its main functions include automatically closing the door, protecting the door body, reducing impact noise, and having the function of fire prevention and smoke isolation. It is widely used in public buildings, residences, and safety passages. Common types include external-mounted type, door-top type, floor spring (door-bottom type), etc.
[0003] During the manufacturing process of the closer housing, a rubber ring needs to be pressed into the connecting hole on its side. For example, it is necessary to manually align the rubber ring and the connecting ring with the connecting hole, and then use tools such as a rubber hammer to knock the rubber ring and the connecting ring into the connecting hole. This installation method has relatively low efficiency, resulting in a reduction in the production efficiency of the closer. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an equipment for pressing rubber rings on a closer housing.
[0005] The purpose of the utility model is achieved through the following technical solutions: An equipment for pressing rubber rings on a closer housing includes a machine base, on which a workbench is constructed. A pressing column is arranged on the workbench, and the pressing column is adapted to be successively sleeved with a connecting ring, a rubber ring, and the connecting hole of the closer housing. A pressing block is also arranged on the workbench in a manner that can be ejected, and the pressing block is used to push the closer housing to press tightly against the rubber ring and the connecting ring side.
[0006] Preferably, the pressing block is ejected under the drive of a cylinder.
[0007] Preferably, a connecting frame is arranged on the workbench, and the pressing block is slidably adapted to the connecting frame.
[0008] Preferably, the connecting frame is in a "冂" shape.
[0009] Preferably, a guiding hole is constructed on the connecting frame, and a guiding column is arranged on the pressing block, and the guiding column is slidably adapted to the guiding hole.
[0010] Preferably, a connecting plate is arranged on the pressing block, and the guiding column is arranged on the connecting plate.
[0011] Preferably, there are two groups of the guiding column and the guiding hole arranged oppositely.
[0012] Preferably, the pressure block is detachably connected to the connecting plate.
[0013] Preferably, the crimping post is also adapted to be a connecting hole that can penetrate the door closer housing, and the end face of the pressing block is provided with a mating hole for the crimping post to extend into.
[0014] Preferably, a positioning block is also provided on the worktable. When the positioning surface of the door closer housing abuts against the positioning block, the connecting hole of the door closer housing is opposite to the pressing post. A wedge structure is also adapted between the pressing block and the positioning block. When the pressing block is pushed out, the wedge structure drives the positioning block to move away from the side of the door closer housing.
[0015] The beneficial effects of this invention are as follows: During operation, the connecting ring, rubber ring, and door closer housing are sequentially fitted onto the pressing post. Then, the pressing block is pushed out, causing it to further press the door closer housing against the pressing post, thereby pressing the rubber ring and connecting ring into and securing them within the connecting hole of the door closer housing. Compared with existing technologies, this invention, through the cooperation of the pressing post and pressing block, enables rapid positioning and pressing of the rubber ring on the door closer housing, resulting in higher installation efficiency and improved door closer production efficiency.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] like Figure 1 , Figure 2 , Figure 3As shown, a door closer housing rubber ring pressing device includes a base 1, which includes a frame and a worktable 2 supported on the frame. The worktable 2 is specifically provided with a connecting frame 6, which can be in a U-shape. For example, a pressing block 4 is provided on the connecting frame 6, which can be ejected by a cylinder 5 or other ejector, and the pressing block 4 is specifically adapted to be ejected to one side of the worktable 2 under the action of the cylinder 5. Correspondingly, a pressing post 3 is provided on the worktable 2.
[0020] The crimping post 3 may include, for example, a stepped shaft. For example, a connecting ring 13, a rubber ring 14, and a connecting hole 15 of the door closer housing 18 may be sequentially inserted into the top of the crimping post 3. At this time, the pressing block 4 can be controlled to push out to one side of the workbench 2. Subsequently, the pushed-out pressing block 4 will push the door closer housing 18 to press further against the crimping post 3, thereby pressing the rubber ring 14 and the connecting ring 13 into and pressing them into the connecting hole 15 of the door closer housing 18.
[0021] In some embodiments, the connecting frame 6 is further provided with guide holes 7, and a connecting plate 9 is slidably adapted within the guide holes 7 via guide posts 8. The aforementioned pressure block 4 is detachably disposed at the bottom end of the connecting plate 9. For example, two sets of guide posts 8 and guide holes 7 are symmetrically arranged on both sides of the connecting plate 9 in a grouped manner. The ends of the two guide posts 8 away from the connecting plate 9 can be fixed to the ejection shaft of the cylinder 5 via mounting plates. Thus, when the ejection shaft of the cylinder 5 ejects, the mounting plate, the two guide posts 8, the connecting plate 9, and the pressure block 4 will be ejected simultaneously. Furthermore, the ejection stability of the pressure block 4 is enhanced by the sliding guidance of the guide posts 8 and guide holes 7.
[0022] As the pressure block 4 wears down, the operator can remove the pressure block 4 from the connecting plate 9 and replace it. For example, the pressure block 4 and the connecting plate 9 can be detached by screwing.
[0023] A guide frame may be provided at the bottom of the top of the connecting frame 6. The guide frame specifically includes a connecting post 16 and a guide plate 17 provided at the bottom of the connecting post 16. The two guide holes 7 are respectively provided on both sides of the guide plate 17 relative to the connecting post 16.
[0024] In a preferred embodiment, the length of the crimping post 3 is preferably sufficient to penetrate the connecting hole 15 of the door closer housing 18. That is, when the connecting ring 13, the rubber ring 14, and the connecting hole 15 of the door closer housing 18 are fitted into the crimping post 3, the end of the crimping post 3 will protrude from the top of the door closer housing 18, and the bottom surface of the pressing block 4 is provided with a mating hole 10 for the crimping post 3 to extend into. Guided by the mating hole 10 and the crimping post 3, the smoothness of the door closer housing 18 when pressed downward is further improved, making the reliability of this utility model higher.
[0025] In some embodiments, a positioning block 11 is also provided on the workbench 2 by means of an elastic element such as a spring. For example, during the process of fitting the door closer housing 18 into the crimping hole, the operator can place the positioning surface of the connecting ear of the door closer housing 18 against the positioning block 11. At this time, under the limitation of the positioning block 11, the connecting hole 15 of the door closer housing 18 will be vertically aligned with the crimping post 3. Then, the door closer housing 18 can be placed downward along the positioning block 11 so that its connecting hole 15 can be smoothly fitted into the crimping post 3, thus making it less likely that the door closer housing 18 will be difficult to fit into the crimping post 3.
[0026] Furthermore, at least one of the aforementioned pressure block 4 or connecting plate 9 is also fitted with a wedge structure 12 between itself and the positioning block 11. The wedge structure 12 is a common structure in the prior art used to change the direction of movement between components, and will not be described in detail here. However, what is particularly different is that as the pressure block 4 is pushed out, the wedge structure 12 will drive the positioning block 11 to move away from the door closer housing 18, thereby preventing mutual friction between the door closer housing 18 and the positioning block 11. When the pressure block 4 is raised again, the positioning block 11 will re-enter the positioning position under the reset of the elastic element, so as to guide the subsequent door closer housing 18 to be fitted into the pressing post 3.
[0027] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
