[0029] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Combination Figure 1-8 This embodiment discloses an automatic assembly machine for steel wire hose clamps, including a frame 1 formed by splicing aluminum alloy profiles and panels, and the frame 1 mainly plays a bearing and supporting role. A horizontal working panel is provided on the top of the frame 1 for assembling other working devices.

[0031] Specifically, a pressing device 3 is provided on the frame 1, and the pressing device 3 is provided with a sink 32 for accommodating the wire clamp, and a tooling constraint component adapted to the wire clamp is provided in the sink 32; the frame 1 is provided with a first feeding device 2 for conveying the wire clamp, a second feeding device 6 for conveying the baffle, a third feeding device 7 for conveying the wafer, a fourth feeding device 8 for conveying the screw, a screw locking device 5 and a transfer device 4 located on the periphery of the pressing device 3; the transfer device 4 is provided with a swing arm 43 that can reciprocate along the "n"-shaped guide groove 421, and a plurality of clamps are provided on the swing arm 43, and the clamps can perform workpiece clamping and transfer operations at the feeding end and the discharging end of the pressing device 3.

[0032] Among them, combined Figure 3 and Figure 4As shown, the first feeding device 2 includes a support frame 21, a column is arranged at the bottom of the outer end of the support frame 21, the column is made of aluminum alloy profile, and an adjustable support foot is arranged at the bottom of the column. The inner end of the support frame 21 is connected and fixed to the frame 1, and the main body of the support frame 21 is a plate structure in a horizontal state. A track plate 22 is arranged on the top of the support frame 21 through a pad. Horizontal track grooves 221 are arranged at the upper and lower ends of the track plate 22. A round belt 23 is clamped in the track groove 221, and one end of the round belt 23 is connected to the feeding motor 24 through a specific turntable transmission. The feeding motor 24 adopts a stepping reduction motor. The feeding motor 24 can drive the round belt 23 to slide in the track groove 221, and the track plate 22 remains stationary during this process. The round belt 23 is used to receive the conveying wire clamp. A U-shaped sensor 25 for controlling the discharge speed is arranged on one side of the track plate 22. The arrival detection of the material is carried out in conjunction with the U-shaped sensor 25 to control the start and stop state of the round belt 23.

[0033] It should be noted that the track plate 22 is a vertical plate structure, and its two side walls constitute an anti-bias limiting structure for the wire clamp clamped on the round belt 23. That is to say, the wire clamp is clamped on the track plate 22 and the top of the round belt 23, and the track plate 22 serves as a lateral limit for it. The round belt 23 serves as a transmission structure, which can drive the wire clamp to move toward one side of the pressing device 3 to transport the material.

[0034] The second feeding device 6, the third feeding device 7 and the fourth feeding device 8 include a vibrating plate and a straight vibrator, which can stably supply the corresponding parts. Among them, the output end of the fourth feeding device 8 is provided with a pneumatic feeding assembly, which can stably supply the screws one by one; an independent transfer structure is provided between the third feeding device 7 and the pressing device 3, and the transfer structure specifically adopts a combination structure of a lateral movement module and a pneumatic clamp, which is a prior art, and its specific structure and working principle are not described here in detail. Those skilled in the art can select and implement from the prior art according to the actual operation situation.

[0035] Combination Figure 5 , Figure 7 and Figure 8 As shown, the pressing device 3 includes a base 31 connected to the frame 1, the base 31 is a block structure, the sink 32 is a "cross" shaped slot structure arranged on the top of the base 31, and the slots on the left and right sides of the sink 32 are provided with clamping blocks 33, and the bottom of the clamping block 33 is connected to the clamping drive assembly, and the clamping drive assembly is specifically as shown in FIG. Figure 7 As shown, it includes a crank 331, a connecting rod 332 and a first cylinder 333 connected to each other. The first cylinder 333 is fixedly connected to the base 31. The telescopic rod of the first cylinder 333 is vertically arranged and can drive the bottoms of the two symmetrically arranged cranks 331 to move up and down. The bottom of the crank 331 is hinged to the telescopic rod of the first cylinder 333 ( Figure 5 and Figure 7The clamp block 33 is in a separated state, but the actual structure is a closed connection relationship), and can swing left and right following the up and down movement of the telescopic rod of the first cylinder 333. The top of the clamp block 33 is a ball head structure, which is compatible with the inverted "V"-shaped groove at the bottom of the clamp block 33. The swing of the crank 331 can drive the clamp block 33 to slide left and right in the sink groove 32. It should be noted that for the sake of sliding stability, a limiting structure is provided between the clamp block 33 and the sink groove 32, so that only stable left and right sliding can be performed.

[0036] During actual work, the clamping drive assembly can drive the clamp block 33 to slide left and right, and the clamp block 33 can be synchronously closed toward the center to form a clamping and fixing structure for the wire clamp located on the inside. A clamping groove of the outer contour of the video wire clamp is provided on the inner wall of the clamp block 33. Since the wire clamp has a large circle structure, a small circle structure is provided on the top of the inner side of the large circle structure. The clamp block 33 corresponds to the large circle structure. During actual work, it may be radially extruded to cause it to deform appropriately, so that subsequent assembly can be carried out more smoothly.

[0037] Further, combined with Figure 8 As shown, a positioning rod 34 is arranged in the slot hole at the rear side in the front-to-back direction of the sink 32. The positioning rod 34 in this embodiment has two rod bodies spaced apart from each other. The adjacent sides of the two rod bodies are provided with arc surfaces adapted to the small ring structure of the wire clamp. The positioning rod 34 is transmission-connected with a positioning drive assembly. The positioning drive assembly specifically includes a wedge block 341 located at the rear side of the positioning rod 34. The front end surface of the wedge block 341 forms an adapted inclined docking surface with the rear end surface of the positioning rod 34. The bottom of the wedge block 341 is connected to a second cylinder 342. The second cylinder 342 is connected and fixed to the base 31, and the second cylinder 342 can drive the wedge block 341 to move up and down. It should be noted that a limit guide structure that can only move up and down is provided between the wedge block 341 and the base 31, and a limit guide structure that can only interact horizontally forward and backward is provided between the positioning rod 34 and the base 31, and a return spring is provided between the positioning rod 34 and the base 31. The expansion and contraction direction of the return spring is horizontally forward and backward, and it abuts between the base 31 and the positioning rod 34. In a free state, it can drive the positioning rod 34 to move backward.

[0038] In actual operation, the positioning drive assembly can drive the positioning rod 34 to move forward and backward, and the positioning rod 34 can form a positioning constraint structure for the wire clamp located at the front side after moving forward. Specifically, the second cylinder 342 drives the wedge block 341 downward, and its butt joint surface squeezes the rear end surface of the positioning rod 34, so that the positioning rod 34 moves forward, and the front side of the positioning rod 34 is inserted into the small circle structure of the front wire clamp, which constrains and fixes the wire clamp so that the wire clamp will not rotate around its axial center line, which is convenient for the assembly of subsequent parts. After the assembly is completed, the second cylinder 342 controls the wedge block 341 to move upward, and the positioning rod 34 automatically moves backward with the help of the reset spring to prepare for the next activity.

[0039] The sink 32 located at the front side in the front-to-back direction of the sink 32 provides a feeding space for the disc.

[0040] Further, such as Figure 6 As shown, the transfer device 4 includes a base 41 connected to the frame 1, the base 41 is a gantry structure, a workbench 42 is provided on the base 41, the workbench 42 is specifically a vertical plate structure, the guide groove 421 is arranged on the vertical end face of the workbench 42, the swing arm 43 is pivotally connected to the workbench 42, and a slider connection structure is pivotally connected between the swing arm 43 and the guide groove 421, the swing arm 43 is transmission-connected to the transfer motor 44, the transfer motor 44 is fixed on the workbench 42, and the transfer motor 44 can drive the swing arm 43 to reciprocate along the guide groove 421.

[0041] The clamp includes a first clamp 45 and a second clamp 46 which are spaced apart on the left and right sides of the bottom of the swing arm 43. The first clamp 45 and the second clamp 46 use pneumatic clamps which are connected to an external air compressor and can clamp parts. In order to ensure the stability of the stroke of the swing arm 43, an in-place sensor 47 is provided on the workbench 42. The two ends of the swing stroke can be combined with the in-place sensor 47 to achieve stable and precise control.

[0042] It should be noted that the first clamp 45 can transfer the wire clamp between the first feeding device 2 and the pressing device 3, and the second clamp 46 can transfer the baffle between the pressing device 3 and the second feeding device 6. In addition, the second clamp 46 can also transfer the entire finished product to the discharging device 9 at the middle position of its stroke for discharge and output during the outward movement process. The discharging device 9 adopts a discharging slide rail structure.

[0043] During the specific implementation process, the first feeding device 2 conveys the wire clamps one by one, and the wire clamps are in a vertical state. The small circle structure of the wire clamps is located at the top, and is clamped by the first clamp 45 at the output end of the first feeding device 2 and transferred to the sink 32 of the pressing device 3. Then, the clamping blocks 33 move inwards to clamp and fix the large circle of the wire clamp to the left and right, and the positioning rod 34 moves forward to position and constrain the small circle structure, so that the wire clamp as a whole is in a tooling constraint state. During this process, the second feeding mechanism prepares the baffle, the third feeding mechanism prepares the disc, and the fourth feeding mechanism prepares the screw. The swing arm 43 moves in the opposite direction to transfer the first clamp 45 to the output end of the first feeding mechanism. During this process, the second clamp 46 synchronously clamps the baffle at the output end of the second feeding mechanism and transfers it to the threshold position of the pressing device 3, and the independent transfer structure of the third feeding mechanism also clamps the disc The disk is transported to the threshold position of the pressing device 3. After the screws are in place, the screw feeding device locks the screws. During this process, the screws pass through the baffle and the disc, and form a clamping relationship with the joint of the wire clamp until the locking completes the assembly process of the wire throat clamp. When the first clamp 45 performs the second cycle of wire clamp supply action, the second clamp 46 maintains the clamping of the baffle in the first cycle, and in the process of the first clamp 45 moving inward (moving from the output end of the first feeding device 2 to the pressing device 3), it moves outward synchronously (moving from the pressing device 3 to the output end of the second feeding device 6). When it moves outward to just above the discharging device 9, the clamping action is released, so that the finished product in the first cycle falls to the discharging device 9 for discharge, and the second clamp 46 then moves into position to clamp and transport the baffle of the second cycle, and such a cycle is repeated to realize the automated assembly process of the wire throat clamp.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
