The fixing device includes a bottom plate, on the front and back of the top end of which arc-shaped plates are fixedly installed. On both sides of the bottom plate, clamping devices are fixedly installed, and the clamping devices include clamping boxes.

[0003] It drives the main gear to rotate by rotating the rotating rod and drives the driven gear to rotate. Then, it drives the first threaded rod to rotate by rotating the driven gear and drives the threaded clamping block to move. Then, it clamps with the arc-shaped plate through the threaded clamping block, effectively realizing the fixation of the spring, avoiding the spring from falling off during the pressing and combining process, thus easily causing injury to the staff and ensuring the safety of the spring pressing and combining device during use.

[0004] The technical solution in this comparative document has the function of fixing the spring to avoid the situation of falling off during pressing and combining. However, the defects brought are more obvious. For example, when pressing and combining the spring, the uneven force on the top surface of the spring will cause the spring to bend or bulge in the middle during the pressing and combining process, and the protection effect of this solution for spring pressing and combining is poor. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a spring pressing and combining device, which solves the problems that when pressing and combining the spring, the uneven force on the top surface of the spring will cause the spring to bend or bulge in the middle during the pressing and combining process, and the protection effect of this solution for spring pressing and combining is poor.

[0006] To achieve the above object, the utility model provides the following technical solution: A spring pressing and combining device includes a base, on the surface of which a hydraulic telescopic rod is fixed, and a lower pressing plate is arranged at the top end of the hydraulic telescopic rod. A pressing and combining component is arranged on the surface of the base, and a slidable lifting structure is arranged inside the pressing and combining component;

[0007] The pressing and combining component includes sleeves fixedly connected to the surface of the base in a rectangular array, and a slidable lower pressing rod is arranged inside the sleeves. The lower pressing rod is fixedly connected to the bottom surface of the lower pressing plate.

[0008] In a specific embodiment, a chute is opened on the side surface of the sleeve, and the lifting structure is slidably connected inside the chute.

[0009] In a specific embodiment, the lifting structure includes a slider slidably connected inside the chute, and an extension rod for convenient gripping is provided on the side of the slider. A lifting plate is fixed on the other side of the slider, and the outer diameter of the lifting plate fits the inner diameter of the sleeve.

[0010] In a specific embodiment, a rubber sleeve is provided on the surface of the extension rod on the side of the slider, and grooves for increasing friction are arranged in a circular array on the surface of the rubber sleeve.

[0011] In a specific embodiment, support feet are arranged in a rectangular array on the bottom surface of the base, and strip-shaped patterns for anti-slip are provided on the bottom surfaces of the support feet.

[0012] In a specific embodiment, sliding rods are fixed in a rectangular array on the bottom surface of the lower pressing plate, and sliding tubes are slidably connected to the surfaces of the sliding rods. The sliding tubes are fixedly connected to the surface of the base.

[0013] Compared with the prior art, the present utility model provides a spring pressing and combining device, which has the following beneficial effects:

[0014] In the technical solution disclosed by the present utility model, the spring is placed inside the sleeve, the pressing rod moves downward to squeeze the spring located inside the sleeve, and the inner wall of the sleeve limits the surface of the spring, which plays a role in preventing it from deforming or bulging in the middle during the pressing and combining process.

[0015] Through the pressing and combining assembly provided by the present utility model, a spring that fits the inner diameter of the sleeve is placed in. The hydraulic telescopic rod contracts to drive the lower pressing plate fixed at the top to move downward, so that the pressing rod fixed on the bottom surface of the lower pressing plate moves downward synchronously and slides into the inside of the sleeve to press and combine the spring placed inside the sleeve. Since the outer diameter of the spring completely fits the inner diameter of the sleeve, when the spring is squeezed, it will not deflect and deform or bulge in the middle, thus achieving the effect of protecting the spring during pressing and combining and preventing damage.

Specific implementation manner

[0022] The following will cooperate with the drawings and embodiments to detail the implementation manner of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0023] Figures 1-4 This is an embodiment of the present utility model, a spring pressing and combining device, including a base 1, a hydraulic telescopic rod 2 is fixed on the surface of the base 1, and a lower pressing plate 3 is arranged at the top end of the hydraulic telescopic rod 2. A pressing and combining component 4 is arranged on the surface of the base 1, and a slidable lifting structure 5 is arranged inside the pressing and combining component 4.

[0024] The specific problem addressed by this specific embodiment is: when pressing and combining a spring, uneven force on the top surface of the spring will cause it to bend or bulge in the middle during the pressing and combining process, and this solution has a poor protective effect on the spring during pressing and combining. The present utility model places the spring inside the sleeve 41, and the lower pressing rod 42 moves downward to squeeze the spring located inside the sleeve 41. The inner wall of the sleeve 41 limits the surface of the spring, preventing it from deforming or bulging in the middle during the pressing and combining process.

[0025] The pressing and combining component 4 includes sleeves 41 fixedly connected to the surface of the base 1 in a rectangular array, and a slidable lower pressing rod 42 is arranged inside the sleeves 41. The lower pressing rod 42 is fixedly connected to the bottom surface of the lower pressing plate 3. In this specific embodiment, a chute is opened on the side of the sleeve 41, and the lifting structure 5 is slidably connected inside the chute. Place a spring that fits the inner diameter of the sleeve 41 into it. The hydraulic telescopic rod 2 contracts to drive the lower pressing plate 3 fixed at the top to move downward, so that the lower pressing rod 42 fixed to the bottom surface of the lower pressing plate 3 moves downward synchronously and slides into the inside of the sleeve 41 to press and combine the spring placed inside the sleeve 41. Since the outer diameter of the spring completely fits the inner diameter of the sleeve 41, when the spring is squeezed, it will not shift and deform or bulge in the middle, thus achieving the effect of protecting the spring during pressing and combining and preventing it from being damaged.

[0026] In this specific embodiment, the lifting structure 5 includes a slider 51 slidably connected inside the chute, and an extension rod for convenient gripping is provided on the side of the slider 51. A lifting plate 52 is fixed on the other side of the slider 51, and the outer diameter of the lifting plate 52 fits the inner diameter of the sleeve 41. A rubber sleeve 6 is provided on the surface of the extension rod on the side of the slider 51, and grooves for increasing friction are formed in an annular array on the surface of the rubber sleeve 6;

[0027] Through the arrangement of the lifting structure 5, the compressed spring is inside the sleeve 41 after pressing and combining. The slider 51 can be slid to drive the lifting plate 52 fixed on the side to move upward inside the sleeve 41, pushing out the placed spring, which is convenient for workers to take the spring inside the sleeve 41.

[0028] In this specific embodiment, support feet 7 are arranged in a rectangular array on the bottom surface of the base 1, and strip-shaped patterns for anti-slip are provided on the bottom surface of the support feet 7. Slide bars 8 are fixedly arranged in a rectangular array on the bottom surface of the lower pressing plate 3, and a slide tube 9 is slidably connected to the surface of the slide bars 8. The slide tube 9 is fixedly connected to the surface of the base 1;

[0029] Through the mutual cooperation of the slide tube 9 and the slide bar 8, during the movement of the lower pressing plate 3, the slide bar 8 and the slide tube 9 improve the stability of assisting the movement of the lower pressing plate 3.

[0030] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in this field. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.
