A conveying part for conveying the pins 100 is horizontally arranged above the notch of the seating groove a1, and includes a conveyor belt and two sprockets a6, and a carrying plate a7, wherein the conveyor belt includes a belt body a2 and a pair of parallel and spaced chains a5, and the belt body a2 is connected between the two chains a5 to move synchronously therewith. Chain a5 with sprocket a6 corresponds the meshing transmission still be connected with on the area body a2 and be the setting element a3 that pin 100 was put to L type gesture, setting element a3 is the channel-section steel structure of vertical setting and its opening side sets up towards the input direction of pin 100, the bottom of setting element a 3's pi type inner chamber with the one end of a rectangle strip hole a4 on the area body a2 aligns, UNICOM. The length direction of the rectangular bar hole a4 is consistent with the length direction of the belt body a2, and the other end of the rectangular bar hole a4 faces the input side of the pin 100, and the length and width of the rectangular bar hole a4 need to make the pin 100 directly leak from the rectangular bar hole a4 when being placed in a master L-shaped posture. Meanwhile, the bearing plate a7 is horizontally arranged below the belt body a2, and the rectangular bar hole a4 at the position outside the position where the belt body a2 moves to the placing groove a1 is completely closed, so that the pin 100 is smoothly transported and prevented from leaking from the rectangular bar hole a 4. When in use, the vertical section of the pins 100 in the L-shaped position is vertically inserted into the n-shaped inner cavity, so that the pins 100 which are positioned in the rectangular strip holes a4 and limited in the placing position by the positioning pieces a3 can leak into the placing groove a1 when being transported to the upper part of the placing groove a1.

When the hanger is used, the strap body a2 can be firstly positioned above the positioning groove a1, the pins 100 are placed in the positioning piece a3 and placed in the master L-shaped posture, the pins 100 positioned in the rectangular bar holes a4 move towards one side of the positioning groove a1 along the conveying direction of the conveyor belt under the supporting action of the bearing plate a7, when the pins move to a certain position above the notch of the positioning groove a1, the corner parts of the pins 100 begin to leak downwards and enter the notch of the positioning groove a1, and the pins 100 are conveyed forwards continuously along with the conveyor belt, the pins 100 fall into the bottom of the positioning groove a1 in a mode that the vertical section and the corner parts of the pins 100 placed in the master L-shaped posture first land, finally lean against the positioning groove a1, and the top ends of the pins 100 are exposed out of the notch of the positioning groove a1, therefore, the length of the rectangular bar holes a4 is designed to be as long as possible so as to allow enough time for the conveyor belt to move upwards, and prepare for taking away the front installation space between the subsequent pins 100 and the insulator 200.

A sliding plate b2 is horizontally and slidably arranged on the base b1 close to the step surface of the vertical side wall b3 of the step, and the upper surface of the sliding plate b2 participates in forming the inner bottom surface of the rectangular cavity b 34. With vertical lateral wall b3 of step is provided with outer dog b4 relatively and upright, and the side that outer dog b4 deviates from vertical lateral wall b3 of step includes the arc surface on upper portion and the vertical plane of lower part, and outer dog b4 can be on the step face horizontal slip and its one side that deviates from vertical lateral wall b3 of step links to each other with the support b6 of vertical setting through first spring b5, support b6 bottom mounting is in the edge of step face, and the top has the blind hole of a vertical setting, installs the second spring b7 of a vertical setting in the blind hole, and the top of second spring b7 stretches out outside the blind hole and connects a adjustable shelf b8 that only can vertical removal, and second spring b7 plays supporting role to adjustable shelf b 8. A blind cavity is formed in the movable frame b8, the top end of the blind cavity is opened, a U-shaped opening b10 is formed in the side wall of the outer stop block b4, a third spring b9 is vertically installed in the blind cavity, and in a free state, the top end of the third spring b9 is higher than the bottom of the opening b10 and is connected with a horizontal section of a gamma-shaped stamping rod b 11. The horizontal section can horizontally move left and right, an extrusion rod is further vertically fixed on one side of the movable frame b8 facing the outer stop block b4, and a roller b12 is installed at the bottom end of the extrusion rod. The bottom end of the vertical section of the punching rod b11 is provided with a punching block, the punching block comprises a main block b13 and a sub-block b32, the main block b13 and the sub-block b32 are elastically and telescopically connected in the horizontal direction and are always on the same horizontal line, for example, a sliding connecting shaft b33 is adopted for connection, and a cylindrical spring is sleeved on the sliding connecting shaft b33 to realize elastic expansion. Preferably, the length of the punching block in the non-working state is 1.2-1.5 times of the horizontal width of the punching cavity.

Meanwhile, the horizontal section of the punching rod b11 is further fixedly connected with a pressing handle b18 used for being connected with a main shaft of the press machine, for example, when the left and right placing grooves a1 are arranged, the two pressing handles b18 are respectively connected with a horizontally arranged telescopic shaft, one end, close to each other, of each telescopic shaft is simultaneously connected with a T-shaped block, and the top end of each T-shaped block is used for being in contact with and transmitting force to the main shaft of the press machine. When the pressing handle b18 is pressed downwards, the punching rod b11 slides downwards vertically under the guiding action of the notch b10, and in the process: the roller b12 is firstly contacted with the arc surface of the outer baffle plate so as to gradually extrude and push the outer stop block b4 towards one side of the step vertical side wall b3, when the movable frame b8 is contacted with the top end of the bracket b6, the outer stop block b4 is pushed to a position for sealing the rectangular cavity b34 towards the opening of one side of the step edge, and at the moment, the outer stop block b4 and the rectangular cavity b34 together form a rectangular accommodating groove a1 with only an open top; when the punching block is pressed down to the limit position, the pin 100 stands in an L shape and rests on the vertical side wall of the rectangular cavity b 34.

When the stamping device is used, the stamping rod b11 gradually moves downwards, the horizontal section of the stamping rod compresses the second spring b7 and the third spring b9, when the roller is firstly contacted with the arc surface at the upper part of the side surface of the outer stop block b4, the stamping block is not contacted with the outer stop block b4, continuously, when the roller moves downwards to the limit, namely the movable frame b8 is contacted with the top end of the bracket b6, the outer stop block b4 and the rectangular cavity b34 form a rectangular placing groove a1 with only the top open, and at the moment, the stamping block is about to enter the placing groove a1 or enters the placing groove a1. As the pressing rod b11 is pressed further downwards, the third spring b9 is compressed further, and the press block is pressed further, so that finally, when the press block is pressed to the limit position, the pin 100 stands in an L shape, rests on the vertical side wall of the rectangular cavity b34, and the pin 100 is limited to the preset position. With multiple pins 100, all pins 100 can be quickly moved down by the insulator 200 to make a socket-type through-mount connection. Certainly, the insulator 200 can be directly moved to the position above the placing groove a1 to move downwards after being grabbed by a grabbing device such as an existing manipulator, the insulator is covered on the pins 100 in a pressing mode, and when a plurality of pins 100 are formed, the insulator 200 can be rapidly inserted and assembled in a penetrating mode at one time to form a semi-finished product. When the semi-finished product needs to be taken out, after the pressure on the stamping rod b11 is released, under the elastic force of the second spring b7 and the third spring b9, the stamping rod b11 automatically moves upwards, after the stamping rod b11 moves upwards to a certain height, the second spring b7 jacks up the movable frame b8 to a large extent, so that the roller b12 moves upwards to a position separated from the outer stop block b4 or contacted with the arc surface, the outer stop plate can be automatically pulled back to the original position under the action of the first spring b5, namely, the outer stop plate moves close to one side of the fixed frame, so that the stamping block can have a space moving towards one side of the fixed frame, namely, the stamping rod b11 can move back in the horizontal direction, the stamping block and the assembled insulator 200 are conveniently and completely staggered in the horizontal direction, the stamping block is allowed to move upwards from the arrangement groove a1 and then is separated, and the semi-finished product formed by the assembled pin 100 and the insulator 200 can be smoothly taken out. On the other hand, when the punch presses the pin 100 to correct the posture of the pin 100, the block b32 of the punch presses down and simultaneously applies a horizontal pushing force to the pin 100 toward the vertical side wall of the mounting groove a1, so that the pin 100 is pushed to a predetermined position standing upright in an L shape and depending on the vertical side wall of the rectangular cavity b34, and the slide plate b2 is provided to perfectly assist the correction.

Preferably, in the implementation, a plurality of rollers b30 are installed at the bottom end of the sliding plate b2 to support the sliding of the sliding plate b 2. And both ends of the sliding plate b2 are respectively connected with a fourth spring b31 so as to conveniently reset the sliding plate b 2.

In addition, an adjusting screw is vertically installed in the base b1, one end, penetrating through the top surface of the base b1, of the adjusting screw is rotatably connected with an adjusting block b19, the adjusting block b19 participates in enclosing the rectangular cavity b34 towards one side of the rectangular cavity b34, and therefore the arrangement of the pins 100 with the length in a larger range can be achieved, and the adaptability is stronger.

In addition, to realize the vertical movement of the movable frame b8, there are many methods, and the recommended structure of the embodiment is as follows: the movable frame b8 slides vertically under the guidance of a guide rod b36, the top end of the guide rod b36 penetrates through the movable frame b8 in a sliding fit manner to extend out of a springboard b38 on the top end face of the support b6, and the bottom end of the guide rod b36 is fixedly connected with the side wall of the support b 6. The structure is simple and compact, the integrity is good, and in order to continue the lifting effect, an auxiliary plate b37 is horizontally and fixedly connected to the side wall of the movable frame b8, and the top end of the guide rod b36 penetrates through the auxiliary plate b37 in a sliding fit manner, so that the movement is more stable and reliable.

In order to avoid the extrusion rod from touching the base b1 to damage the base b1 and simultaneously enable the roller b12 to be more stable when leaning against the middle part of the stop block as much as possible to form the placing groove a1, when the placing groove a1 is formed, the roller b12 is not contacted with the base b1, and the roller b12 is tangent to the vertical plane of the lower part of the outer stop block b 4.

For the above-mentioned implementation structure of the first assembling part, in order to adjust the height of the insulator 200 sleeved on the pin 100 at some time, as shown in fig. 5, 6 and 9, a lead screw b15 may be additionally provided, the lead screw b15 is vertically and rotatably installed in the vertical section of the punching rod b11, a threaded block b14 is threadedly sleeved on the lead screw b15, and one end of the threaded block b14 can contact with one side of the insulator 200 moving downward after extending out of the vertical bar hole on the vertical section. With this arrangement, after the punch block sets the posture of the pin 100, the screw rod b15 is rotated so that the screw block b14 moves by a predetermined height to block the insulator 200 from moving downward, thereby controlling the downward movement height of the insulator 200 and controlling the installation position height of the insulator 200 on the pin 100. Furthermore, in order to facilitate accurate control and adjustment of the height value, an annular code wheel b16 is fixedly connected above the horizontal segment of the stamping rod b11, the upper surface of the code wheel b16 has a numerical value representing the height position, the top end of the screw rod b15 penetrates through the center of the code wheel b16 and is fixedly connected with a hand wheel b17, and the top end of the screw rod b15 close to the code wheel b16 is also connected with a pointer b35 along the radial direction thereof, and the pointer b35 points to the numerical value.

Finally, in the present embodiment, with reference to fig. 10 to 12, the second fitting part is structured as follows: the device comprises a workbench c4 for placing the pins 100 in the L-shaped placing posture, wherein a sensor c8 is installed on the workbench c4, and a press mounting disc c7 capable of being pressed downwards is arranged right above the position, for placing the pins 100, on the workbench c 4. The automatic transmission system is arranged above the workbench c4 and comprises wire wheels and conveying ropes, the wire wheels comprise 4 outer wire wheels c1 and inner wire wheels c2, the 4 outer wire wheels c1 and the 4 inner wire wheels c2 respectively form a rectangle for arrangement, and each 4 wire wheels are positioned at four corners of the corresponding rectangle. The conveyer rope is equipped with two and transversal rectangle of personally submitting, and every conveyer rope is around taking turns to 4 lines that correspond to form a rectangular wire frame that is the tensioning state, and the outer rectangular wire frame of tensioning is located the outside of the interior rectangular wire frame of tensioning on the inner reel c2 on the outer reel c1, two sidelines c3 that outer rectangular wire frame and interior rectangular wire frame just are one by one each other pass the two strip caulking grooves of insulated cap 300 respectively. The insulating cap 300 is correspondingly attached to the right angle of the groove bottom at the edge of the strip-shaped caulking groove, and the two side lines c3 are always away from each other, so that the insulating cap 300 is firmly erected on the two side lines c 3; when the sensor c8 detects that the insulation cap 300 is conveyed to the position right above the pin 100 by the two side lines c3, the press disc c7 is pressed down to mount the insulation cap 300 on the top end of the pin 100.

In a specific manufacturing process, the working table c4 can accommodate the insulator 200 and the pin 100 that have been inserted through, and the structure of the working table c4 can be designed by referring to the aforementioned accommodating groove a1 of the first assembling component, or the first assembling component is directly used to pre-install the connected pin 100 and the insulator 200, that is, the working table c4 is the first assembling component. In use, after the insulator 200 is installed, the pins 100 are pre-positioned using the pressing and positioning action of the punch. On the other hand, with the help of the special structure of the two strip-shaped caulking grooves of the insulating cap 300, under the tightening action of the two side lines c3, erection and conveying are carried out, specifically, the open ends of the strip-shaped caulking grooves of the insulating cap 300 are downward and are pressed down along the length direction of the two side lines c3 after being directly aligned, and as the lower part of the outer side of the inner side wall of each strip-shaped caulking groove is provided with an arc-shaped protruding part protruding inwards, the bottom of each strip-shaped caulking groove is provided with an accommodating space when the side lines c3 penetrate through, and the strip-shaped caulking grooves can be directly connected in series on one side line c3 (conveying rope) when a plurality of insulating caps 300 are pressed and mounted one by one. At this moment, the conveying rope can be taken down or cut short, so that the collection and arrangement of the connectors can be realized, the batch information can be conveniently recorded, and the device is very useful. As for the shape of the rectangular wire frame, the spacing of side lines c3 on a plurality of sides can be changed on one production line to realize press mounting of the insulating caps 300 with a plurality of models (different spacing of the strip-shaped caulking grooves), and the specification production is diversified and flexible. In addition, for the erection and fixation of the pair of side lines c3 to the insulating cap 300, the side wall at the notch of the strip-shaped caulking groove is thinnest, so that the distance between the two corresponding side lines c3 is large, and the bottom of the strip-shaped caulking groove is thicker, so that the distance between the two corresponding side lines c3 is smaller, thereby setting that the insulating cap 300 can be stably buckled on the pair of side lines c3, and the method is also quite ingenious and suitable.
