Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hose clamp assembly equipment, in particular to a semi-automatic hose clamp assembly machine. Background Art
[0002] Hose clamps (rubber tube clamps) are widely used in the fields of automobiles, tractors, locomotives, ships, mines, petroleum, chemical industry, pharmaceuticals, agriculture, etc. They can tightly clamp flexible hoses on rigid parts and are used for sealing in the fields of water, oil, steam, dust, etc. They are ideal connecting fasteners. Hose clamps are now mainly divided into three types: British, American, and German. In addition, there are other derivative products such as tube bundles and strong types.
[0003] At present, many hose clamp assembly machines use a turntable as the transmission structure for the processing stations of hose clamps. Tooling seats are arranged on the turntable to fix the hose clamps. However, the structures of many current tooling seats are relatively simple. Mainly, a sunk groove structure that matches the contour of the hoop band and the hoop head is used to realize the tooling fixation of the hose clamp. In fact, there is still a certain gap between the sunk groove structure and the hose clamp. This gap will cause attitude deviation of the hose clamp during screw tightening or other clamping processes, resulting in faults such as inclined screws being forcibly tightened and damaging the thread structure, or the clamping device not clamping firmly and being prone to falling off during transfer. Summary of the Utility Model
[0004] The utility model provides a semi-automatic hose clamp assembly machine, which is beneficial to solving the problems that the tooling structures of some existing hose clamp assembly machines are relatively simple and the tooling stability is relatively lacking, resulting in prone processing failures.
[0005] The utility model is realized as follows:
[0006] A semi-automatic hose clamp assembly machine includes a frame. On one side of the frame, there are a first feeding device and a second feeding device respectively for supplying hoop bands and screws. The output end of the first feeding device is connected to a first feeding part located on the frame, and the output end of the second feeding device is connected to a second feeding part located on the frame. Between the first feeding part and the second feeding part, there are a transfer device, a curling device, and a turntable. There are also a screw locking device and a discharging device on the frame. The turntable is located inside the second feeding part. A number of tooling seats in central symmetry are arranged on the turntable. A tooling groove adapted to the contour of the hose clamp is provided at the top of the tooling seat. A pressing part is movably connected to one side of the tooling seat. The pressing part can horizontally displace relative to the tooling seat. A pressing claw is provided on the side of the pressing part close to the tooling groove. The pressing claw can cooperate with the tooling groove to form an up-and-down constraint tooling structure for the hose clamp.
[0007] On the basis of the above technical solution, the tooling seat includes a base and a top seat. The base is arranged on the top end surface of the turntable. There is a sunken platform on one side of the top of the base. The top seat is arranged on this sunken platform. After installation, the top surface of the top seat is flush with the top surface of the non-sunken platform area of the base. The tooling groove is arranged on the top end surface of the top seat. There is a chute on the top surface of the non-sunken platform area of the base. The axis of the hose clamp in the tooling groove is parallel to the long side direction of the chute, and the pressing member can reciprocate along the chute.
[0008] On the basis of the above technical solution, the pressing member includes a main body. There is a pressing claw on one side of the main body. There is a concave positioning groove on one side of the main body. There is a convex block protruding upward on the top of the main body.
[0009] On the basis of the above technical solution, a positioning member is arranged on one side of the chute. The positioning member is perpendicular to the long side direction of the chute, and the inner end of the positioning member has a ball head extending into the chute. When the main body of the pressing member slides to the threshold position in the chute, the positioning groove and the ball head of the positioning member will form a positioning and clamping structure.
[0010] On the basis of the above technical solution, a limiting member is arranged on the side of the chute away from the tooling groove. The limiting member can prevent the pressing member from falling off from the outside of the chute.
[0011] On the basis of the above technical solution, the pressing end surface of the pressing claw is provided with an arc surface structure adapted to the inner side surface of the hose clamp.
[0012] On the basis of the above technical solution, a first controller and a second controller are arranged on the frame outside the turntable. There is a lever adapted to the position of the convex block on the first controller. There is a push block adapted to the position of the flange on the second controller. The lever and the push block are respectively connected with driving members, which can control the displacement of the pressing member at the threshold position.
[0013] On the basis of the above technical solution, a detachable connection structure is arranged between the top seat and the base.
[0014] On the basis of the above technical solution, the tooling groove is of a "T" structure.
[0015] On the basis of the above technical solution, a shaping member is arranged on the top seat on one side of the tooling groove.
[0016] Compared with the prior art, the utility model has at least the following advantages:
[0017] The utility model sets a tooling groove on the tooling seat. The tooling groove can serve as the basic tooling structure for the hose clamp during the processing. With the displacement of the pressing part relative to the tooling seat, the pressing claws on the pressing part can press the hose clamp in the tooling groove, and cooperate with the tooling groove to form the upper and lower constraint tooling structure of the hose clamp, making the tooling of the hose clamp more stable and reliable, and reducing the tooling instability caused by the gap remaining between the tooling groove and the hose clamp. This is conducive to solving the problem that the tooling structure of some existing hose clamp assembly machines is relatively simple and the tooling stability is relatively lacking, resulting in easy occurrence of processing failures.

[0031] Combined with Figure 1-8 , this embodiment discloses a semi-automatic hose clamp assembling machine, including a frame 100 assembled by aluminum alloy profiles and aluminum alloy panels. The frame 100 mainly plays a role of bearing and supporting, and its top is a horizontal end face for installing various working devices.
[0032] On one side of the frame 100, there are a first feeding device 200 and a second feeding device 300 respectively for supplying hoop bands and screws. The first feeding device 200 and the second feeding device 300 are arranged at intervals, and their output ends are respectively located on the front and rear sides of the top end face of the frame 100. Both the first feeding device 200 and the second feeding device 300 are vibrating disk feeding devices, which are prior art. Their specific structures and working principles will not be elaborated here. Those skilled in the art can select and implement from the prior art according to the actual operation situation.
[0033] Furthermore, the output end of the first feeding device 200 is connected to a first feeding member 1 located on the frame 100. The first feeding member 1 adopts a conveyor belt structure for linearly conveying the hoop bands. It should be noted that the hoop bands are semi-finished products with the hoop heads pre-fixed into an integrated structure by manual or mechanical devices.
[0034] The output end of the second feeding device 300 is connected to a second feeding member 6 located on the frame 100. The second feeding member 6 adopts a blowing-type screw feeder, which is prior art. Its specific structure and working principles will not be elaborated here. Those skilled in the art can select and implement from the prior art according to the actual operation situation.
[0035] Between the first feeding member 1 and the second feeding member 6, there are a transfer device, a curling device 3 and a turntable 5. On the frame 100, there are also a screw locking device 7 and a discharging device 8. The discharging device 8 adopts a combined structure such as pneumatic claws and a sliding module. The above-mentioned devices are all prior art. Their specific structures and working principles will not be elaborated here. Those skilled in the art can select and implement from the prior art according to the actual operation situation.
[0036] Specifically, the transfer device includes a first transfer member 2 for conveying materials between the first feeding member 1 and the curling device 3, and also includes a second transfer member 4 between the curling device 3 and the turntable 5. Both the first transfer member 2 and the second transfer member 4 adopt pneumatic claws with sliding modules, and are configured with corresponding pneumatic turntables 5 for clamping, conveying and transferring the hoop bands before and after curling. The structures of the above-mentioned transfer members are prior art. Their specific structures and working principles will not be elaborated here. Those skilled in the art can select and implement from the prior art according to the actual operation situation.
[0037] The turntable 5 is located inside the second feeding member 6. The turntable 5 is a horizontally arranged disk structure, and a vertical rotating shaft is connected to the bottom of its central position. The rotating shaft is connected to a stepper motor, which can drive the turntable 5 to rotate step by step.
[0038] The turntable 5 is provided with a number of tooling seats in a centrally symmetrical relationship. In this embodiment, the number of tooling seats is 6. A tooling groove 53 adapted to the contour of the throat hoop is provided on the top of each tooling seat. The tooling groove 53 can serve as the basic tooling structure of the throat hoop during the processing. The tooling seat is movably connected with a holding member 9 located on one side of the tooling groove 53. The holding member 9 can be horizontally displaced relative to the tooling seat. The holding member 9 is provided with a holding claw 92 on the side close to the tooling groove 53. The holding claw 92 can cooperate with the tooling groove 53 to form the upper and lower constraint tooling structure of the throat hoop, making the tooling of the throat hoop more stable and reliable, and reducing the instability of the tooling caused by the gap between the tooling groove 53 and the throat hoop.
[0039] Further, combined with Figure 3 As shown, the tooling seat includes a base 51 and a top seat 52. The base 51 is arranged on the top end surface of the turntable 5. A sinking platform is arranged on one side of the top of the base 51. The sinking platform is located on the left side in the figure. The top seat 52 is detachably arranged on the sinking platform through the cooperation of screws and countersunk threaded hole structures. After installation, the top surface of the top seat 52 is flush with the top surface of the non-sinking platform area of the base 51. The tooling slot 53 is a "T" structure, and the hoop head part of the throat hoop can be inserted into the tooling slot 53.
[0040] The tooling groove 53 is arranged on the top end surface of the top seat 52, and a slide groove 54 is arranged on the top surface of the non-sunken area of the base 51. The axial direction of the throat clamp in the tooling groove 53 is parallel to the long side direction of the slide groove 54 (the left and right direction in the figure), and the holding piece 9 can reciprocate along the slide groove 54, and the holding claw 92 can be laterally inserted or broadcast out of the inner side of the throat clamp. When inserted, the holding claw 92 and the tooling groove 53 cooperate to restrain the hoop head part at the bottom of the throat clamp, so that the throat clamp maintains the tooling stability and will not shake or dislocate easily.
[0041] like Figure 4 As shown, the pressing member 9 includes a main body 91, a pressing claw 92 is provided on one side of the main body 91, the pressing claw 92 is composed of two horizontal rods, the outer side of which is a free end, and the inner side is connected to the main body 91 to form an integrated structure, a concave positioning groove 93 is provided on one side of the main body 91, the positioning groove 93 is close to the bottom of the main body 91, and an upwardly protruding block 94 is provided on the top of the main body 91, and the block 94 is a square flange structure.
[0042] Furthermore, a positioning member 56 is provided on one side of the slide groove 54. The positioning member 56 is perpendicular to the long side direction of the slide groove 54, and the inner end of the positioning member 56 has a ball head 561 extending into the slide groove 54. In this embodiment, the number of the positioning members 56 is two, and the two positioning members 56 are spaced apart from each other and are respectively used for positioning the two end points of the sliding in and out stroke of the pressing member 9. The positioning member 56 adopts a ball head 561 plunger. When the main body 91 of the pressing member 9 slides to the threshold position in the slide groove 54, the positioning groove 93 and the ball head 561 of the positioning member 56 will form a positioning clamping structure. Figure 5As shown. It should be noted that, in order to ensure the smoothness of the clamping action, inclined end faces are provided on both the left and right sides of the positioning groove 93, so that the cross-sectional profile of the positioning groove 93 is a "V"-shaped notch structure. In other embodiments, a spring can also be configured axially on the positioning member 56, and the spring abuts between the positioning member 56 and the base 51, enabling the positioning member 56 to perform axial elastic sliding, making the clamping between the positioning member 56 and the positioning groove 93 more smooth, and its elastic tightness can be designed according to actual requirements.
[0043] Further, a limiting member 55 is provided on the side of the sliding groove 54 away from the tooling groove 53. The limiting member 55 is a convex column structure threadedly locked at the outer end of the sliding groove 54, and the limiting member 55 can prevent the pressing member 9 from falling off the outside of the sliding groove 54.
[0044] In order to achieve better pressing quality during pressing and avoid excessive rigid extrusion deformation of the hose clamp, the pressing end face of the pressing claw 92 is provided with an arc surface structure adapted to the inner side surface of the hose clamp.
[0045] Refer to Figure 3 , a shaping member 57 is provided on the side of the top seat 52 located in the tooling groove 53. The shaping member 57 is located inside the top seat 52, and a guiding groove is provided at its central position. Its function is that when the hose clamp is locked and tightened on the tooling seat, the hoop band will gradually tighten and the diameter change will gradually become smaller. During this process, the guiding groove can play a role in guiding and restraining the hoop band, making the hoop band always in a vertical posture before and after the diameter change, which is beneficial to the subsequent clamping stability.
[0046] Combined with Figures 6 to 8 , a first controller a and a second controller b are provided on the frame 100 outside the turntable 5. A lever a3 adapted to the position of the convex block 94 is provided on the first controller a, and a push block b1 adapted to the flange position is provided on the second controller b. The lever a3 and the push block b1 are respectively connected to driving members, which can control the displacement of the pressing member 9 at the threshold position.
[0047] Specifically, the first controller a includes a first driving member a1 and a second driving member a2 which are stacked. The bottom of the first driving member a1 is connected to the frame 100 through a bracket. Both the first driving member a1 and the second driving member a2 are cylinders. The linear movement directions of the output ends of the first driving member a1 and the second driving member a2 are both horizontal and perpendicular to each other. Among them, the lever a3 is located at the output end of the second driving member a2. The lever a3 can slide in and out relative to the tooling seat. Since the first controller a is located outside the tooling seat at the threshold position, when the first controller a drives the lever a3 to move inwards (this movement direction is perpendicular to the sliding direction of the pressing member 9), the lever a3 can be located on one side of the convex block 94 of the pressing member 9 on the tooling seat at this threshold position. Subsequently, cooperating with the first driving member a1 for lateral movement in another direction (this movement direction is the direction of the pressing member 9 from one side of the tooling groove 53 to the outside of the sliding groove 54), the lever a3 can abut against the inner side of the convex block 94 and push the pressing member 9 outwards along the sliding groove 54, so that the pressing claw 92 moves outwards to disengage from the hose clamp, releasing the restraint control on the hose clamp.
[0048] The second controller b adopts a cylinder structure, and its output end is connected to the push block b1. Relative to the tooling seat at the threshold station, the movement direction of the push block b1 is that the pressing member 9 moves from the outside of the sliding groove 54 to one side of the tooling groove 53, and the movement path of the push block b1 is collinear with the sliding groove 54. When the push block b1 moves, it can push the convex block 94, drive the pressing member 9 to slide along the sliding groove 54, and further make the pressing claw 92 insert into the inner side of the hose clamp to form a pressing restraint structure on the hose clamp.
[0049] In the specific implementation process, the hoop band enters the top of the frame 100 from the first feeding device 200 and the first feeding member 1. The first transfer member 2 transfers it to the curling device 3, and the curling device 3 performs curling processing on it. The second transfer member 4 transfers it to the tooling seat on the turntable 5. The second controller b drives the pressing member 9 to clamp and restrain the hose clamp, and step by step rotates through each processing station in turn, including screw feeding and screw tightening. Subsequently, the first controller a drives the pressing member 9 to move outwards to release the clamping restraint on the hose clamp, and finally the discharging device 8 clamps and transports it out.
