Detailed Implementation

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0036] like Figures 1 to 20 As shown, the semi-automatic pull rod sleeve system of this embodiment includes a pull rod feeding mechanism and a pull rod sleeve mechanism 4 arranged downstream of the pull rod feeding mechanism; the pull rod feeding mechanism sequentially includes a pull rod pressing mechanism 1 and a pull rod feeding drive mechanism 3, and a pull rod pushing mechanism is arranged on one side of the pull rod feeding drive mechanism; the pull rod feeding drive mechanism includes at least one set of drive wheels 7, which are used to realize the forward feeding of the pull rod 20 through the friction between them and the pull rod 20; the pull rod pushing mechanism includes a push rod 21, which is used to push the pull rod 20 to a predetermined position. When the drive wheel 7 cannot act on the pull rod, the pull rod 20 is pushed forward; the pull rod clamping mechanism includes at least one set of clamping driven wheels 15, the upper clamping driven wheel of the clamping driven wheel 15 can be rotated; the pull rod sleeve mechanism includes an outer beveled sleeve 24 that can move along the linear movement direction of the pull rod, and an inner beveled sleeve 22 that cooperates with the outer beveled sleeve; the inner wall of the outer beveled sleeve cooperates with the outer wall of the inner beveled sleeve to clamp the rubber tube 26 arranged between the inner wall and the outer wall, so that the pull rod can enter the rubber tube 26, and finally realize the sleeve operation of the pull rod.

[0037] To facilitate the movement of the beveled sleeve 24 and enable sleeve installation, a slide rail 23 is provided at the bottom of the outer beveled sleeve 24. The outer beveled sleeve 24 is connected to the piston rod of the pneumatic cylinder 27 of the pull rod sleeve mechanism that drives its linear movement. The pull rod sleeve mechanism pneumatic cylinder drives the sleeve to perform the sleeve installation. (See [reference]) Figure 11 As shown.

[0038] In addition, referring to Figure 11 , 12 , in order to fix the hose 26 more stable, the outer sleeve 24 is arranged on the wall of the sleeve hose pressing bolt 25, the sleeve hose pressing bolt is arranged along the radial direction of the outer sleeve, can be multiple, arranged along the circumferential direction of the outer sleeve, the circumferential direction of the outer sleeve is spaced apart to form a bolt hole, which is a plurality of threaded holes, as Figure 15 , so that the hose pressing bolt can further press the hose tightly in the inner sleeve, prevent the hose from falling off during the pull rod sleeve.

[0039] Wherein, in the sleeve, the pull rod sleeve mechanism pneumatic cylinder 27 extends, promotes the outer sleeve 24 along the slide rail 23 to move to the inner sleeve 22, the outer sleeve will press the hose 26, and clamp it on the inner sleeve, enter the clamping state as Figure 12 , by tightening the hose pressing bolt 25 on the wall of the outer sleeve, further press the hose. After that, the pull rod is driven by the feeding mechanism to pass through the sleeve into the hose 26, until the whole sleeve process is completed. After the sleeve is finished, the pull rod sleeve mechanism pneumatic cylinder retracts to separate the outer sleeve from the inner sleeve, and the hose 26 is released and transferred to the next station with the pull rod.

[0040] In this application, the pull rod sleeve mechanism is used to realize the clamping of the hose 26 and the guiding function of the pull rod 20. The inner sleeve and the outer sleeve are designed in the form of flange mounting, which is convenient for fixed installation with the base. Since the two sleeves are easy to wear, they are also convenient to replace. The inner sleeve is used to pass into the inner hole of the hose, which plays a supporting role. The four pieces at the end have a certain elasticity, which plays a guiding role, making it easier to pass into the inside of the hose. The minimum inner diameter of the outer sleeve is 1-2mm larger than the outer diameter of the hose, and the hose 26 can pass through the center hole. The embodiment of the application uses a rod sleeve mechanism pneumatic cylinder to push the outer sleeve 24 to move left and right on the slide rail, so as to realize the automatic clamping of the hose 26 by the cooperation and separation of the inner and outer sleeves, improve the automation degree of the pull rod sleeve, and greatly reduce the labor cost.

[0041] In addition, in some embodiments, in order to control the upper pressing driven wheel to flip, so as to facilitate the pressing of the pull rod 20 and prevent the pull rod from moving, the pull rod pressing mechanism includes a flip pneumatic cylinder 17 for controlling the upper pressing driven wheel to flip. Preferably, the pressing driven wheel is in multiple groups, therefore, in order to better control the upper pressing wheel to flip, two flip pneumatic cylinders are provided to control two groups of pressing driven wheels, of course, other number of flip pneumatic cylinders 17 can be arranged according to the need, wherein the flip pneumatic cylinder is connected with the upper pressing driven wheel seat 16 of the upper pressing driven wheel through a connecting rod mechanism 19, referring to Figure 6As shown, the tension rod is pressed by the upper and lower pressing driven wheels. The tension rod pressing mechanism is designed as a reversible structure, and the extension and retraction of the reversing pneumatic cylinder 17 drives the reversing and closing of the upper pressing driven wheels, facilitating the insertion of the tension rod.

[0042] In the present application, the tension rod pressing mechanism preferably includes five sets of pressing driven wheels 15, wherein the lower five pressing driven wheels 19 are fixed on the base plate and only have rotating function; the upper five pressing driven wheels are fixed on the upper pressing driven wheel seat 16 and can be reversed under the action of the connecting rod mechanism 19 driven by the reversing pneumatic cylinder 17; in addition, the inner hexagonal screw 18 on the upper pressing driven wheel seat 16 can be used to move the upper pressing driven wheel seat up and down under the action of the adjustable pressing spring to adjust the pressing force of the pressing driven wheels.

[0043] The embodiment of the present application uses two sets of tension rod pressing mechanisms, which can effectively reduce the axial movement of the tension rod when driving forward, and because of the added reversing mechanism, the worker no longer needs to slowly push the tension rod from the rear to the roller driving mechanism, but only needs to use the cylinder to reverse the upper part of the tension rod pressing mechanism, put the tension rod, and finally close it by the cylinder.

[0044] In some embodiments, a tension rod dust removal mechanism is arranged between the tension rod pressing mechanism and the tension rod advancing mechanism, including at least one set of dust removal brushes 12, preferably steel brushes, driven to rotate by a motor, used to remove impurities on the tension rod and polish the tension rod during the feeding movement of the tension rod. Specifically, the dust removal brushes are driven to rotate by the turbine reduction motor 14 through the dust removal mechanism gear set 13, to realize dust removal and polishing treatment on the surface of the tension rod, as shown in Figure 4 and Figure 5 Specifically, the turbine reduction motor 14 is connected with the dust removal mechanism gear set through a shaft coupling to drive the dust removal brushes to rotate, thereby removing impurities from the tension rod between the two pairs of steel brushes and polishing them. Preferably, the dust removal brush has a wire diameter of 0.3 mm and a brush outer diameter of 90 mm.

[0045] In some embodiments, as shown in Figure 2 and Figure 3As shown, a hand wheel 9 is arranged above the mounting frame of the driving wheel, the shaft body of the hand wheel is connected with the upper mounting plate of the driving wheel 7 through an adjustable compression spring 8, the compression amount of the adjustable compression spring can be controlled by rotating the hand wheel, so that the compression force of the driving wheel can be adjusted, which can prevent slipping between the driving wheel and the pull rod during the feeding process of the pull rod, wherein preferably, the driving wheel 7 is rotated by a servo reducer motor 11 through a driving mechanism gear set 10 to clamp and forwardly convey the pull rod, specifically, the servo reducer motor is connected with the driving gear set through a shaft coupling to drive the rotation of the driving wheel, and the forward feeding of the pull rod is realized through the friction between the driving wheel and the pull rod. The adjustable compression spring is arranged in the pull rod compression mechanism and the pull rod advancing mechanism in the embodiment of the application, so that the compression force of the pull rod in the two mechanisms is controllable, which can prevent the phenomenon of slipping between the driving wheel and the pull rod due to too small compression force, and can also enable the driven roller to fully compress the pull rod to prevent axial movement of the pull rod.

[0046] In one preferred embodiment, the push rod 20 is rotatable and linearly movable under the action of driving force, as shown in Figure 9 、 Figure 10 The push rod 20 can form a U-shaped structure through a connecting plate and a guide rod, and when not in use, the push rod can be rotated to one side through the handle of the connecting plate, and when in use, the push rod can be rotated to the working position, aligned with the pull rod 20, and then controlled to move forward to realize the forward pushing of the pull rod 20, as shown in Figure 10 Preferably, the diameter of the push rod is the same as the diameter of the pull rod. In addition, a stroke limiting device 35 is arranged at the front end of the guide rod of the push rod 20 to limit the movement position of the push rod 20. Since a certain length of the pull rod cannot be fed to the last stage, a rotatable push rod is designed in the application to help the pull rod advancing mechanism to realize the feeding of the last length.

[0047] As shown in Figure 9 、 10 When the pull rod 20 is fed to the state as shown in Figure 9 , the driving wheel cannot contact the pull rod and thus cannot continue to drive the pull rod to advance, at this time, the push rod 21 needs to be used to move forward under the friction with the driving wheel to push the pull rod in front to continue to feed, as shown in Figure 10 When the push rod moves to a certain stroke, the pull rod is completely fed into the hose, the sleeve process is completed, and the movement can be stopped, so the stroke limiting device as shown in Figure 9 、 10 is designed to stop the continuous feeding of the push rod by the pull rod feeding mechanism.

[0048] In one preferred embodiment, as shown in Figure 17 、 18, 19, 20, the semi-automatic pull rod sleeve system, further comprises a pull rod transfer system, is located behind the sleeve, completes the transfer of the sleeve pull rod, preferably, the pull rod transfer system comprises a rubber tube seat overturning mechanism 5, including a reversible rubber tube seat 31, the rubber tube seat is connected with a rubber tube seat overturning pneumatic cylinder 28; the discharge side of the rubber tube seat is a slope 32, see Figure 19 , further, the rubber tube seat 31 is connected with an upper cover 29, the rubber tube seat and the fixed seat are hinged, and the upper cover and the rubber tube seat are hinged, the upper cover has a handle 30, facilitating manual operation, opening or covering the upper cover 20, the rubber tube seat 31 has a trapezoidal groove with a trapezoidal cross section, to facilitate the placement of the pull rod sleeved with the rubber tube 26, as shown in Figure 19 .

[0049] In a preferred embodiment, the pull rod transfer system further comprises a pull rod skip mechanism 6, including a skip 33 for receiving the pull rod sent by the rubber tube seat overturning mechanism, the skip is connected with an electro-hydraulic driver 34 for controlling the overturning of the skip, as shown in Figure 20 , after the pull rod is sleeved with the rubber tube, the rubber tube seat overturns the pull rod under the driving of the pneumatic cylinder, the pull rod rolls along the slope into the skip of the pull rod transfer mechanism, and when the pull rod in the skip reaches a certain number, it is transferred to the next process.

[0050] In use, the pull rod 20 is driven forward by the pull rod feeding drive mechanism, is pressed by the pull rod pressing mechanism to prevent movement, and is cleaned and polished by the dust removal mechanism, then the rubber tube is clamped and fixed by the pull rod sleeve mechanism, and finally the pull rod is driven to pass through the rubber tube hole, thereby realizing the sleeve function; after the pull rod completes the sleeve, it comes to the rubber tube seat overturning mechanism, the sleeve pull rod is overturned by the cylinder, rolls along the slope to the pull rod skip mechanism, and when the sleeve pull rod in the skip reaches a certain number, the electro-hydraulic driver extends to drive the skip to rotate, and the pull rod is transferred to the next process.
