Description

Technical Field

[0001] The utility model relates to the field of spring clamping machines, in particular to an automatic chain spring clamping machine. Background Art

[0002] A circlip, also called a retaining ring or a snap ring, is a type of fastener that is installed in the shaft groove or hole groove of a machine or equipment. It prevents the axial movement of parts on the shaft or hole. Installing the circlip on the chain can fix the chain accessories and connect two accessories. At the same time, it can maintain the gap between the accessories to prevent them from loosening or falling off during movement. Most importantly, the circlip can also be used to buffer the impact or vibration between mechanical parts to prevent them from being excessively damaged, thereby protecting the chain mechanical parts and preventing them from being damaged or worn during use.

[0003] In the actual chain assembly process, the chain and the retaining ring are mainly assembled by moving the extrusion assembly on the top of the retaining ring machine downward, and the roller that moves downward squeezes the inclined slot block at the bottom of the retaining ring machine, driving the retaining block to move the chain. Since the distance from the extrusion assembly on the top of the retaining ring machine to the bottom conveying assembly is fixed, it is impossible to realize the conveying operation of chains of different sizes. Based on this, an automatic chain retaining ring machine is provided, which is easy to adapt to chains of different sizes for assembling retaining rings. Utility Model Content

[0023] A horizontal slide groove 201 is provided on the upper wall of the spring clamp machine 101, and a storage box 202 is slidably connected inside the horizontal slide groove 201. Both ends of the outer wall of the storage box 202 are fixedly connected to a first spring 203, and one end of the first spring 203 is fixedly connected to a solid block 204. The bottom wall of the solid block 204 is fixedly connected to the upper wall of the spring clamp machine 101;

[0024] One end of the outer wall of the storage box 202 is rotatably connected to a one-way hook 205 via a connecting rod, and a first torsion spring is provided between the rotating shaft of the one-way hook 205 and the connecting rod;

[0025] The storage box 202 is provided with a lifting assembly 3 inside, and the lifting assembly 3 includes:

[0026] A lifting slot 301 is provided on the upper wall of the storage box 202, a second spring 302 is fixedly connected to the bottom wall of the lifting slot 301, a trapezoidal block 303 is fixedly connected to the top of the second spring 302, a fixing plate 304 is fixedly connected to the outer wall of the trapezoidal block 303, a storage slot 305 is provided on the upper wall of the fixing plate 304, a second torsion spring 306 is provided inside the storage slot 305, one end of the second torsion spring 306 is fixedly connected to the fixing plate 304, the other end of the second torsion spring 306 is fixedly connected to a rotating rod 307, the rotating rod 307 extends to the top of the storage box 202, and a locking block 308 is fixedly connected to the outer wall of the rotating rod 307;

[0027] A vertical slide groove 5 intersecting with the lifting groove 301 is provided inside the storage box 202 at the fixed plate 304, and a locking block 4 for locking the position of the trapezoidal block 303 is provided on the outer wall of the vertical slide groove 5 at the fixed plate 304;

[0028] The trapezoidal block 303 is inclined downward in an arc when viewed from the front, so as to squeeze the roller 104 when it moves downward, so as to make it move horizontally.

[0029] In the present embodiment, it should be supplemented that: the clamping assembly 102 and the spring clamp machine 101, as well as the extrusion assembly 103 and the roller 104 are detachably connected by bolts, and the clamping assembly 102 includes a track for guiding the movement of the chain joint and a material guide limiting column distributed on the top of the track for limiting the placement and unloading of the spring clamp. The positions of the extrusion assembly 103 and the material guide limiting column are staggered. When the chain is assembled with the spring clamp, the spring is limited and placed in the middle of a plurality of material guide limiting columns. The roller 104 and the extrusion assembly 103 are driven downward synchronously by the electric push rod 105, and the roller 104 will squeeze the conveying assembly 2 to make the conveying assembly 2 move horizontally. The horizontal movement of the conveying assembly 2 causes the one-way hook 205 to move and connect with a section of the chain link. The convex shaft is squeezed, at this time, the one-way hook 205 will be forced to rotate and shrink its first torsion spring deformation, and its chain remains stationary. After the one-way hook 205 passes through the convex shaft, it will automatically reset under the action of the first torsion spring. At the same time, the extrusion component 103 moves down to squeeze the chain link at the corresponding position (the convex shaft on this chain link is equipped with a retaining spring). The extrusion component 103 can squeeze the retaining spring and move it down to completely clamp it on the outside of the convex shaft. In this way, the retaining spring of this chain link is assembled, and then the electric push rod 105 moves up and resets. At this time, the transmission component 2 is reset synchronously, and its one-way hook 205 uses the hook-shaped convex shaft to drag the chain outward, so that the chain link assembled with the retaining spring moves forward, and the chain link with the retaining spring that is automatically blanked moves to the bottom of the extrusion component 103. In this reciprocating manner, the automatic assembly of the retaining spring of the chain can be realized;

[0030] When it is necessary to assemble the retaining spring for the chain of other models, first replace the clamping assembly 102 and the extrusion assembly 103 as a whole to adapt to the chain of this size. After replacing the clamping assembly 102 and the extrusion assembly 103, adjust the height of the trapezoidal block 303 to make the roller 104 move down and extrude the transmission assembly 2. The horizontal movement spacing matches the chain link length of the new model. At this time, hold the rotating rod 307 and rotate it 180 degrees clockwise, so that the locking block 308 on the outer wall of the rotating rod 307 changes from the initial contact with the blocking block 4 to the state away from the blocking block 4. At this time, the synchronous position lock of the fixed plate 304 and the trapezoidal block 303 is released, and the second spring 302 drives the trapezoidal block 303 to move upward until it is After the trapezoidal block 303 is adjusted to the appropriate position, the rotation of the rotating rod 307 is gradually loosened. At this time, the second torsion spring 306 drives the rotating rod 307 to rotate 180 degrees for reset. At this time, the rotating and reset rotating rod 307 drives the locking block 308 to rotate synchronously until the locking block 308 rotates to the gap of the positioning block 4 again, thereby realizing the synchronous position locking of the fixed plate 304 and the trapezoidal block 303. By adjusting the height of the trapezoidal block 303, the initial contact height of the roller 104 and the trapezoidal block 303 is different, thereby changing the horizontal movement distance of the roller 104 squeezing the transmission component 2, so as to match chain links of different lengths. Through the cooperation of the above parts, the purpose of being able to quickly assemble the retaining spring for chains of different sizes is achieved.

[0031] Please refer to Figure 3 There are multiple positioning blocks 4 vertically distributed on the outer wall of the fixing plate 304 , and the distance between each two adjacent positioning blocks 4 matches the height of the locking block 308 .

[0032] In this embodiment: in order to limit the lifting and lowering movement of the locking block 308, a plurality of blocking blocks 4 with a spacing matching the height of the locking block 308 are arranged on the outer wall of the fixed plate 304, so that two adjacent blocking blocks 4 can just limit the up and down movement of the blocking blocks 4.

[0033] Please refer to Figures 2-3 The length of the locking block 308 is smaller than the length of the vertical slide groove 5 , and the length of the locking block 308 is larger than the distance from the outer wall of the rotating rod 307 to the outer wall of the locking block 4 .

[0034] In this embodiment: in order to achieve synchronous position locking and position unlocking of the fixed plate 304 and the trapezoidal block 303, the length of the locking block 308 is set to be smaller than the length of the vertical slide groove 5 and at the same time larger than the distance from the outer wall of the rotating rod 307 to the outer wall of the locking block 4, so that when the locking block 308 is on one side of the fixed plate 304, the synchronous position locking of the fixed plate 304 and the trapezoidal block 303 is achieved, and when the locking block 308 is away from the fixed plate 304, the position locking of the fixed plate 304 and the trapezoidal block 303 is released.

[0035] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
