Description

Technical Field

[0001] This utility model belongs to the field of gas spring processing technology, specifically relating to a new type of gas spring processing sealing machine. Background Technology

[0002] In the production and processing of gas springs, it is necessary to seal the end edge of the gas spring shell, that is, to bend the end edge of the shell inward, thereby limiting the gas spring and preventing it from loosening or falling off from the port of the shell. In the existing technology, this is mainly done by a rolling machine, which is not only very complex in structure, but also unsuitable for small-batch production environments due to its large size. It also greatly increases the processing and usage costs and is cumbersome to operate, thus limiting its applicability. Summary of the Invention

[0003] The purpose of this utility model is to provide a new type of gas spring processing and sealing machine with a reasonable structural design that is conducive to improving ease of use.

[0004] The technical solution to achieve the purpose of this utility model is a new type of gas spring processing and sealing machine, including a support and a processing platform set on the top surface of the support. The processing platform is provided with a positioning channel, and a cylindrical clamping and positioning seat for placing and positioning the gas spring is provided in the positioning channel.

[0005] A rotary motor is fixed inside the bracket, and the bottom end of the cylindrical clamping and positioning seat is connected to the rotary motor. The rotary motor drives the cylindrical clamping and positioning seat to rotate.

[0006] The top surface of the processing platform is provided with a pressure limiting structure and a pressure sealing structure, which are located at both ends of the diameter of the positioning channel.

[0007] The pressure sealing structure includes a sealing wheel that is rotatably connected by a bearing, and the connection between the bottom surface and the side surface of the sealing wheel is an arc-shaped surface;

[0008] The arc-shaped surface presses against the opening of the gas spring's outer shell and is used to squeeze the opening of the gas spring's outer shell outward to achieve a seal.

[0009] A further preferred embodiment is that the pressure sealing structure also includes a base, a telescopic cylinder, a slide rail, and a slider;

[0010] The telescopic cylinder is fixed on the base, and the slider is slidably mounted on the slide rail and connected to the piston shaft of the telescopic cylinder.

[0011] The top surface of the slider is fixed with a connecting seat, and the sealing wheel is located on the bottom surface of one end of the connecting seat with the edge of the sealing wheel extending out of the end face of the connecting seat.

[0012] A further preferred embodiment is that the pressing and limiting structure includes a vertical support rod, a transverse convex plate fixed on the vertical support rod, and two abutting rollers connected to the bottom end of the transverse convex plate through a bearing, with the wheel edges of the two abutting rollers extending out of the end face of the transverse convex plate.

[0013] The housing of the gas spring, located within the positioning channel, is positioned between two positioning rollers.

[0014] A further preferred embodiment is that a limit sensor is fixed on the base, and a limit contact is fixed on the slider;

[0015] The slider moves horizontally on the slide rail, and the limiting contact block presses against the upper limit of the limiting sensor.

[0016] A further preferred embodiment is that both the sealing wheel and the positioning roller are metal wheels.

[0017] A further preferred embodiment is that the processing platform is equipped with a control switch button.

[0018] Its working principle is briefly described as follows: When in use, the assembled gas spring is inserted into the cylindrical clamping and positioning seat and locked in place. At this time, the outer surface of the gas spring is pressed between the two positioning rollers and can rotate effectively. At the same time, the arc-shaped surface of the sealing wheel is pressed against the position of the gas spring outer shell that needs to be sealed by the telescopic cylinder. The rotary motor is started, and the gas spring outer shell rotates together. Under the pressure of the sealing wheel, the opening of the gas spring outer shell is squeezed inward to complete the sealing. When the sealing wheel is pressing, the force of the pressing roller can ensure that the position of the gas spring outer shell will not tilt or shift.

[0019] This utility model has positive effects: its structure is reasonable and has few components. Through the pressure limiting structure and sealing wheel, it can effectively and quickly seal the opening of the gas spring shell, improving sealing efficiency and stability. At the same time, it is easy to operate, suitable for processing environments of all sizes, and has a wide range of applications and strong applicability. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0027] See Figures 1 to 4 As shown, a novel gas spring processing and sealing machine includes a support 1 and a processing platform 2 disposed on the top surface of the support. The processing platform has a positioning channel 3, within which a cylindrical clamping and positioning seat 4 for placing and positioning the gas spring is disposed. In this embodiment, the clamping end sidewall of the cylindrical clamping and positioning seat has a strip-shaped buffer groove, a conventional structure in the prior art. The cylindrical clamping and positioning seat can be tightened by rotating a locking member with a conical inner hole, or by locking and positioning with screws, etc. These are common-sense operations and are therefore not described in detail. To ensure processing effectiveness, a rotary motor is fixed inside the support. The bottom end of the cylindrical clamping and positioning seat is connected to the rotary motor, which drives the cylindrical clamping and positioning seat to rotate. Through this structure, the gas spring 11 can be rotated, and in conjunction with the pressure sealing structure, the opening of the gas spring's outer shell can be sealed by full-circumferential compression.

[0028] In practical applications, the top surface of the processing platform is provided with a pressure limiting structure 5 and a pressure sealing structure 6. The pressure limiting structure and the pressure sealing structure are located at both ends of the diameter of the positioning channel. Since they are set at both ends of the diameter, the pressure limiting structure can limit the position of the gas spring during sealing, thus ensuring the stable position of the gas spring.

[0029] Meanwhile, in practical applications, the sealing structure includes a sealing wheel 61 rotatably connected via bearings. The bottom and side surfaces of the sealing wheel are connected by an arc-shaped surface 7. During processing, the arc-shaped surface presses against the opening of the gas spring's outer shell and is used to squeeze the opening outward to achieve a seal. The arc-shaped surface mainly ensures the effectiveness of the seal and prevents damage to the opening of the gas spring's outer shell.

[0030] In practical applications, the sealing structure further includes a base 62, a telescopic cylinder 63, a slide rail 64, and a slider 65. During assembly, the telescopic cylinder is fixed to the base, and the slider is slidably mounted on the slide rail and connected to the piston shaft of the telescopic cylinder. A connecting seat 66 is fixed to the top surface of the slider, and the sealing wheel is located on one end of the bottom surface of the connecting seat, with the edge of the sealing wheel extending beyond the end face of the connecting seat. The connecting seat allows the sealing wheel to be positioned to the side of the slider without affecting the effectiveness of the slider's translation or the normal rotation of the sealing wheel.

[0031] Meanwhile, the pressure limiting structure includes a vertical support rod 51 and a horizontal protruding plate 52 fixed on the vertical support rod. Two abutting rollers 53 are connected to the bottom end of the horizontal protruding plate via bearings, and the edges of the two abutting rollers extend beyond the end face of the horizontal protruding plate. The outer shell of the gas spring, located within the positioning channel, abuts between the two abutting rollers. In this embodiment, both the sealing wheel and the abutting rollers are metal wheels. The height of the abutting rollers and sealing wheel can be set as needed. The sealing wheel abuts at the opening of the gas spring's outer shell, while the abutting rollers are located on the upper part of the side wall of the gas spring's outer shell, primarily to prevent the outer shell of the gas spring from shifting during sealing.

[0032] Meanwhile, to improve operational stability, a limit sensor 8 is fixed to the base, and a limit contact 9 is fixed to the slider. The slider moves horizontally on the slide rail, and the limit contact 9 presses against the upper limit of the limit sensor. This primarily limits the distance of horizontal movement to prevent excessive displacement or translation. Furthermore, for convenient control, a control switch button 10 is provided on the processing platform. This switch button is used to control the operation of the cylinder and rotary motor.

[0033] Its working principle is briefly described as follows: When in use, the assembled gas spring is inserted into the cylindrical clamping and positioning seat and locked in place. At this time, the outer surface of the gas spring is pressed between the two positioning rollers and can rotate effectively. At the same time, the arc-shaped surface of the sealing wheel is pressed against the position of the gas spring outer shell that needs to be sealed by the telescopic cylinder. The rotary motor is started, and the gas spring outer shell rotates together. Under the pressure of the sealing wheel, the opening of the gas spring outer shell is squeezed inward to complete the sealing. When the sealing wheel is pressing, the force of the pressing roller can ensure that the position of the gas spring outer shell will not tilt or shift.

[0034] This utility model has positive effects: its structure is reasonable and has few components. Through the pressure limiting structure and sealing wheel, it can effectively and quickly seal the opening of the gas spring shell, improving sealing efficiency and stability. At the same time, it is easy to operate, suitable for processing environments of all sizes, and has a wide range of applications and strong applicability.

[0035] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
