Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figure 1-3 As shown, the present invention proposes a composite hose connector crimping device, including a base 1, a mounting plate 2 fixedly connected to the base 1, an electric push rod 3 fixedly installed on one side of the mounting plate 2, and the output end of the electric push rod 3 passing through the mounting plate 2. Two push plates 4 are slidably connected to the base 1 and are symmetrically distributed vertically. The two push plates 4 are hinged to each other. Buckles 8 for fixing the push plates 4 are installed on both the front and rear sides of each pair of push plates 4. A fixing plate 6 located on one side of the push plate 4 is fixedly connected to the base 1, and a support column 5 passing through the fixing plate 6 and the two push plates 4 in sequence is fixedly connected to the base 1. A groove 51 is provided at one end of the support column 5 that passes through the push plate 4. A servo motor 52 is fixedly installed on the side of the groove 51 away from the push plate 4. The output shaft of the servo motor 52 is fixedly connected to a threaded rod 55. A sleeve 54 is threadedly connected to the outside of the threaded rod 55. Several expansion plates 53 that pass through the support column 5 are slidably connected in the groove 51. The expansion plates 53 are distributed in a ring at equal intervals on the support column 5. Several sets of push rods 56 are hinged to the outside of the sleeve 54. The end of each set of push rods 56 away from the sleeve 54 is hinged to the end of each expansion plate 53 located in the groove 51.

[0021] In this embodiment, after the pipe is fitted onto the support column 5 and is to be connected and crimped, the spread plate 53 can support the pipe against the support column 5 and be stably transported to the joint by the push plate 4 at the end of the pipe for stable connection. The crimping is also stably crimped by the crimping component 7, thereby improving the stability of the pipe and joint connection crimping process and thus improving the connection crimping effect.

[0022] It should be noted that the support column 5 is equipped with a clamping element 7 for clamping the pipe and the joint; the inner circumferential wall of the sleeve 54 is provided with an internal thread, and the internal thread is adapted to the external thread on the outside of the threaded rod 55, so that the rotating threaded rod 55 can drive the sleeve 54 to move laterally back and forth along a direction parallel to the horizontal plane. The support column 5 is L-shaped. The expansion plate 53 is T-shaped, and the end of the expansion plate 53 away from the sleeve 54 is arc-shaped. The groove 51 end of the support column 5 is provided with a through hole for the expansion plate 53 to slide. When the push rod 56 pushes the expansion plate 53, the expansion plate 53 can move stably in the through hole toward the center of the sleeve 54. When the expansion plate 53 moves toward the center of the sleeve 54, its arc-shaped end can fit tightly against the inner wall of the pipe to be crimped.

[0023] In addition, a sliding groove is provided on the base 1, and a slider extending into the sliding groove is fixedly connected to the lower end of the bottom push plate 4. The slider is slidably connected to the sliding groove, so that the activated electric push rod 3 can drive the push plate 4 to be stably and horizontally adjusted on the base 1.

[0024] Secondly, a semi-circular fixing groove is provided at one end of each of the two push plates 4, and an anti-slip rubber pad is fixedly connected in the fixing groove. After the pipe is opened by the expansion plate 53 and fits into the fixing groove on the push plate 4, the friction between the fixing groove and the outer surface is increased, so that the horizontally moving push plate 4 drives the pipe to move on the expansion plate 53.

[0025] In an optional embodiment, the clamping member 7 includes a fixed ring 71 fixedly connected to the side of the fixed plate 6 near the push plate 4, and a plurality of connecting rods 72 slidably connected to the inner bottom wall of the fixed ring 71 and distributed in an annular pattern. The end of the connecting rod 72 away from the fixed ring 71 is T-shaped, and a spring 73 is fixedly connected between the T-shaped end and the outer side of the fixed ring 71. A clamping block 74 is fixedly connected to the end of the connecting rod 72 that passes through the fixed ring 71. A rotating ring 75 located outside the fixed ring 71 is rotatably connected to the side of the fixed plate 6 near the push plate 4, and a hydraulic rod 77 is hinged to the fixed plate 6. The output end of the hydraulic rod 77 is hinged to the rotating ring 75. A plurality of abutments 76 distributed in an annular pattern are fixedly connected to the inner side of the rotating ring 75, and each abutment 76 is located diagonally above the T-shaped end of each connecting rod 72.

[0026] In this embodiment, when the activated hydraulic rod 77 pulls the rotating ring 75 to rotate axially on the fixed plate 6, it can drive the abutment block 76 on the rotating ring 75 to rotate as well, so that the abutment block 76 can squeeze the T-shaped end of the connecting rod 72, thereby driving the clamping block 74 to abut against and squeeze the pipe extending to the joint clamping point, so as to perform a ring-shaped compression on the clamping point of the pipe and the joint, thereby performing the clamping process.

[0027] It should be noted that a limiting ring extending into the interior of the fixed plate 6 is fixedly connected to the side of the rotating ring 75 near the fixed plate 6, and an annular rotating groove for the rotating ring 75 to rotate is provided on the side of the fixed plate 6 near the rotating ring 75. This makes the rotation of the rotating ring 75 on the fixed plate 6 more stable when the hydraulic rod 77 drives the rotating ring 75 to rotate and adjust. The cross-section of the rotating groove and the limiting ring are both T-shaped. The side of the abutment 76 near the T-end of the connecting rod 72 is inclined. The limiting ring with a T-shaped cross-section can provide stable rotation of the rotating ring 75 while also preventing the rotating ring 75 from separating from the fixed plate 6. The abutment 76 is arc-shaped, and several abutments 76 together form a circle during the pressing process.

[0028] The working principle in the above embodiments is as follows: Depending on the thickness of the pipe, selectively peel off the outer adhesive layer or not, then start the electric push rod 3 to pull the push plate 4 to slide away from the fixed plate 6, and release the buckle 8 to make the upper push plate 4 rotate towards the mounting plate 2. After folding the push plate 4, the connector to be crimped can be slid into the support column 5 in sequence, and the various components of the connector, such as the core, outer sleeve, sealing ring, etc., are put on the pipe crimping end in the correct order. Then put the pipe on the support column 5, so that the pipe crimping end faces the fixed plate 6 and the connector crimping end faces the mounting plate 2. Apply a small amount of food-grade lubricant to the end of the pipe, such as water, oil or soapy water, to facilitate insertion. Then, unfold the upper push plate 4, fix the buckle 8, and start the electric push rod 3 to drive the push plate 4 to slide to the end of the support column 5. Then start the servo motor 52 to push the sleeve 54 to move horizontally to one side of the mounting plate 2, and support the inner wall of the pipe by spreading the plate 53, and make the pipe close to the fixing groove on the push plate 4. Then start the electric push rod 3 again to push the crimping end of the pipe to move horizontally to the core tube of the connector until the end of the pipe is close to the shoulder of the core tube, and the pipe and connector can be connected. When the hydraulic rod 77 is activated last, it pulls the rotating ring 75 to rotate axially on the fixed plate 6. This causes the abutment 76 on the rotating ring 75 to rotate as well, so that the abutment 76 can squeeze the T-end of the connecting rod 72. This causes the clamping block 74 to abut against and squeeze the pipe to extend to the joint clamping point, so as to perform a ring-shaped compression at the clamping point of the pipe and the joint, thus completing the clamping process of one end of the pipe and the joint. Then, the above steps are repeated to complete the clamping of the other end of the pipe and the joint.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
