Description

[Technical field]

[0001] The utility model belongs to the technical field of bellows assembly, in particular to a bellows clamping mechanism. [Background technology]

[0002] In the water pipe system, the bellows has the advantages of easy assembly, aging resistance, corrosion resistance, and easy shaping. The bellows is usually connected to the quick-connect connector in the water pipe by interference fit. During the connection process, the bellows needs to be limited and fixed to facilitate the docking of the bellows and the quick-connect connector. The existing bellows and quick-connect connectors are generally assembled manually, with one hand holding the bellows and the other hand holding the quick-connect connector. This not only has low work efficiency, but also wastes labor, and the quality is unstable. The product consistency is relatively poor. If the assembly is not in place, it is easy to cause product leakage, and the after-sales maintenance and disassembly costs are very high.

[0003] Therefore, for the assembly of quick-connect connectors for bellows, there are many assembly tools designed in the prior art. For example, patent publication number CN 219170653 U discloses a quick assembly jig for bellows and pagoda heads. The pagoda head is directly inserted into the connector socket of the fixed seat, and then the movable clamp is pushed by the second cylinder. The movable clamp and the fixed clamp are closed to clamp the bellows, and the central axes of the bellows and the pagoda head are in the same straight line. The slider is then pushed by the first cylinder, and the slider drives the translation seat along the guide rail. The translation seat moves with the clamped bellows toward the pagoda head, and the bellows and the pagoda head are sleeved together to ensure the assembly consistency of the bellows and the pagoda head.

[0004] Semicircular grooves are symmetrically provided on the opposite surfaces of the movable clamping block and the fixed clamping block in the above scheme. When the two semicircular grooves are closed, a circular clamping hole for clamping the corrugated pipe is formed. The inner wall of the groove is provided with a profiled groove matching the shape of the outer wall of the corrugated pipe. The outer wall of the corrugated pipe usually has alternately distributed depressions and protrusions. The profiled groove is designed in the groove to cooperate with the corrugated pipe for clamping. The corrugated pipe is clamped by the profiled groove. This method may be suitable for corrugated pipes made of metal or with thicker walls of the corrugated section, but is not suitable for plastic corrugated pipes in water pipes, because the corrugated section of the plastic corrugated pipe has a thinner wall. During assembly, the first cylinder pushes the translation seat to move the clamped corrugated pipe toward the pagoda head. During the forward movement and assembly process, as Figure 1 As shown, it is a schematic diagram of the extrusion of the contoured groove of the bellows clamping fixture on the surface of the bellows during the assembly of the bellows. The contoured groove has a large extrusion force on the concave part of the bellows, which will cause the bellows to rupture and reduce the production yield.

[0005] Therefore, it is necessary to provide a bellows clamping mechanism to solve the above technical problems. [Contents of the utility model]

[0006] The main purpose of the utility model is to provide a bellows clamping mechanism, which solves the problem that the bellows wall is broken when the clamping fixture clamps the bellows, improves the yield rate of the bellows during assembly, and reduces the operating cost.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a bellows clamping mechanism, which includes a support frame, a fixed clamp seat fixed on the support frame, a movable clamp seat arranged opposite to the fixed clamp seat in front and behind, and a driving component for driving the movable clamp seat to approach or move away from the fixed clamp seat, the fixed clamp seat and the movable clamp seat both include a mounting seat and a clamping fixture fixedly installed in the mounting seat and clamping the bellows; the two clamping fixtures are symmetrically provided with semicircular grooves on opposite surfaces, a transition annular groove is provided between the non-corrugated section and the corrugated section of the bellows, and the groove is provided with an annular convex ridge clamped in the transition annular groove.

[0008] Furthermore, when the two semicircular clamping grooves are closed, a circular clamping hole for clamping the corrugated tube is formed.

[0009] Furthermore, a slide rail is provided on the support frame, and the movable clamp seat is slidably arranged on the slide rail via a first sliding block.

[0010] Furthermore, the driving assembly includes a fixed block fixed on the supporting frame, a first connecting rod with one end rotatably arranged on the fixed block, a second connecting rod rotatably connected to the other end of the first connecting rod, a handle fixedly connected to the other end of the first connecting rod, a movable frame rotatably connected to the free end of the second connecting rod, and a push rod fixed on the movable frame, one end of the push rod is fixed to the movable clamping seat, and the movable frame is slidably arranged on the slide rail via a second slider.

[0011] Furthermore, the mounting seat is provided with an open groove penetrating the upper end surface on one opposite side, and a limiting convex ridge is provided on the groove wall of the open groove.

[0012] Furthermore, the clamping fixture is fixedly installed in the open groove, and the outer wall of the clamping fixture is provided with a limiting groove which is installed and matched with the limiting convex ridge.

[0013] Compared with the prior art, the beneficial effect of the bellows clamping mechanism of the utility model is that semicircular grooves are symmetrically opened on the opposite surfaces of the clamping fixture, and the annular ridges on the grooves are clamped into the transition annular grooves of the bellows. When the quick-insert drive mechanism (not shown) drives the bellows clamping mechanism to move, the annular ridges of the grooves abut and squeeze the groove wall of the transition annular groove at the end face of the non-corrugated section. Since the wall of the bellows in the non-corrugated section is thicker, the annular ridges abut and squeeze the transition annular groove at the end face of the non-corrugated section during assembly, which makes it difficult for the annular ridges to abut and squeeze the transition annular groove, which makes it difficult for the annular ridges to abut and squeeze the transition annular groove at the end face of the non-corrugated section. Therefore, the bellows clamping mechanism provided by the present scheme solves the problem of the bellows wall being broken when the clamping fixture clamps the bellows, thereby improving the yield of the bellows assembly and reducing the operating cost.

[0027] Please refer to Figure 2-Figure 8 The present embodiment is a bellows clamping mechanism, the bellows clamping mechanism 100 comprises a support frame 1, a fixed clamp seat 2 fixed on the support frame 1, a movable clamp seat 3 arranged opposite to the fixed clamp seat 2 in front and back, and a driving component 4 for driving the movable clamp seat 3 to move closer to or away from the fixed clamp seat 2.

[0028] The fixed clamp seat 2 and the movable clamp seat 3 both include a mounting seat 31 and a clamping fixture 32 fixedly mounted in the mounting seat 31 and clamping the corrugated tube 200 .

[0029] A first sliding block 33 is fixed below the movable clamping seat 3 , a sliding rail 11 is arranged on the supporting frame 1 , and the first sliding block 33 is slidably arranged on the sliding rail 11 .

[0030] The driving assembly 4 is configured as a connecting rod structure, and the driving assembly 4 includes a fixed block 41 fixed on the support frame 1, a first connecting rod 42 rotatably disposed at one end on the fixed block 41, a second connecting rod 44 rotatably connected to the other end of the first connecting rod 42, a handle 43 fixedly connected to the other end of the first connecting rod 42, a moving frame 45 rotatably connected to the free end of the second connecting rod 44, and a push rod 46 fixed to the moving frame 45, one end of the push rod 46 is fixed to the movable clamp seat 3, and the movable frame 45 is slidably disposed on the slide rail 11 through a second slider 47. The driving handle 43 can use the push rod 46 to push the movable clamp seat 3 toward the fixed clamp seat 2 to clamp the corrugated pipe 200.

[0031] In other embodiments, the driving assembly 4 may be driven by a motor, a cylinder or other driving modes, and the driving assembly 4 drives the movable clamp seat 3 to move toward the fixed clamp seat 2 to clamp the corrugated tube 200 .

[0032] The mounting seat 31 is provided with an opening groove 311 penetrating the upper end surface on the opposite side, and a limiting ridge 312 is provided on the groove wall of the opening groove 311, and a limiting groove 323 is provided on the outer wall of the clamping fixture 32 to be installed and matched with the limiting ridge 312. The clamping fixture 32 is installed in the opening groove 311, and the limiting groove 323 of the clamping fixture 32 cooperates with the limiting ridge 312 of the mounting seat 31 so that the clamping fixture 32 is inserted into the mounting seat 31, and the mounting seat 31 and the clamping fixture 32 are fixedly installed by tightening the bolts. Through the cooperation of the concave-convex structure of the limiting groove 323 and the limiting ridge 312, the mechanism of the mounting seat 31 and the clamping fixture 32 is more stable and reliable.

[0033] The two clamping fixtures 32 are symmetrically provided with semicircular grooves 321 on opposite surfaces. When the two semicircular grooves 321 are closed, a circular clamping hole for clamping the corrugated tube 200 is formed. By clamping the corrugated tube 200 after the two semicircular grooves 321 are closed, the corrugated tube 200 can be firmly clamped to prevent it from shaking, thereby improving the assembly quality.

[0034] The bellows 200 includes a non-corrugated section 201 disposed at one end and a corrugated section 202 disposed at the other end. When the quick-insert connector is assembled with the bellows 200, the quick-insert drive mechanism (not shown) drives the bellows clamping mechanism 100 to move close to the mechanism for clamping the quick-insert connector, so that the quick-insert connector is inserted into the bellows 200 for plug-in assembly. Since the wall thickness of the non-corrugated section 201 is greater than the wall thickness of the corrugated section 202, the bellows 200 is arranged in the non-corrugated section 201 in the section where it is assembled with the quick-insert connector, thereby preventing the wall from being squeezed and ruptured during the assembly process. A transition annular groove 203 is arranged between the non-corrugated section 201 and the corrugated section 202 of the bellows 200, and an annular convex ridge 322 is arranged on the clamping groove 321 of the clamping fixture 32, which is clamped in the transition annular groove 203.

[0035] When the bellows clamping mechanism 100 provided in the present invention is used, the bellows 200 is clamped into the clamping hole of the clamping fixture 32, and at the same time, the annular ridge 322 on the clamping groove 321 of the clamping fixture 32 is clamped into the transition annular groove 203 of the bellows 200, and the quick-insertion drive mechanism (not shown in the figure) drives the bellows clamping mechanism 100 to move close to the mechanism for clamping the quick-insertion connector, so that the quick-insertion connector moves relatively and is inserted into the bellows 200 for assembly ... and the quick-insertion connector moves relatively and is inserted into the bellows 200 for assembly, and the quick-insertion drive mechanism (not shown in the figure) drives the bellows clamping mechanism 100 to move close to the mechanism for clamping the quick-insertion connector, and the quick-insertion connector moves relatively and is inserted into the bellows 200 for assembly, and the quick-insertion drive mechanism (not shown in the figure) drives the bellows clamping mechanism 100 to move close to the mechanism for clamping the quick-insertion connector, and the quick-insertion connector moves relatively and (Note) In the process of driving the bellows clamping mechanism 100 to move, the annular ridge 322 of the clamping groove 321 abuts against and squeezes the groove wall of the transition annular groove 203 at the end face of the non-corrugated section 201. Since the wall of the non-corrugated section 201 of the bellows 200 is thicker, the annular ridge 322 abuts against and squeezes the transition annular groove 203 at the end face of the non-corrugated section 201 during assembly, and it is not easy to break, thereby improving the yield rate of the bellows 200 during assembly and reducing the operating cost.

[0036] The present scheme provides a bellows clamping mechanism, in which semicircular grooves 321 are symmetrically provided on opposite surfaces of a clamping fixture 32, and an annular ridge 322 on the groove 321 is clamped into a transition annular groove 203 of a bellows 200. When a quick-insert driving mechanism (not shown) drives the bellows clamping mechanism 100 to move, the annular ridge 322 of the groove 321 abuts against and squeezes the groove wall of the transition annular groove 203 at the end face of a non-corrugated section 201. Since the wall of the non-corrugated section 201 of the bellows 200 is relatively thick, the annular ridge 322 abuts against and squeezes the transition annular groove 203 at the end face of the non-corrugated section 201 during assembly, and it is not easy for the annular ridge 322 to abut against and squeeze the transition annular groove 203 at the end face of the non-corrugated section 201. Therefore, compared with the prior art, the bellows clamping mechanism 100 provided by the present scheme solves the problem of the bellows wall being broken when the clamping fixture clamps the bellows 200, thereby improving the yield rate during bellows assembly and reducing operating costs.

[0037] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
