[0055] The embodiments of the present application are described in detail below, which are exemplary and intended to explain the present application, and cannot be understood as the limitation of the present application.

[0056] Referring to Figure 12 , the automatic machine shell 15 has an inner hole 1501 along the automatic machine shell axis, and four grooves 1503 are uniformly arranged on the end face of the automatic machine shell; two symmetrically arranged mounting through holes 1502 are radially arranged on the side wall of the automatic machine shell close to the grooves 1503. In order to quickly manually rotate the automatic machine when debugging the product or supplying the gun with bullets, the present embodiment provides a connecting rod type manual rotating device for automatic machine.

[0057] Referring to Figure 1 , a connecting rod type manual rotating device for automatic machine, comprising a locking-unlocking assembly, a connection assembly 1 and a handle assembly 2. The handle assembly 2 is connected with one end of the connection assembly, used for pushing the connection assembly so that the other end of the connection assembly 1 is butted with the groove and the mounting through hole on the automatic machine, and used for pushing the connection assembly 1 to rotate to drive the automatic machine to rotate.

[0058] Referring toFigure 2 The connecting assembly comprises a push rod 3, a positioning pin 4, a connecting pin 5, a rotating disc 6, a large spring 7 and a connecting rod 8. One end of the push rod 3 penetrates through the center hole of the rotating disc 6, and the large spring 7 is coaxially installed on the push rod 3 and close to the rotating disc 6. When the push rod 3 is pushed, the end surface of the rotating disc 6 can abut against the end of the large spring 7. Two ends of the connecting rod 8 are hingedly connected with one end of the push rod 3 through a connecting pin 5. The other ends of the connecting rod 8 are hingedly connected with one end of the two symmetrically arranged positioning pins 4 through another connecting pin 5. The rotating disc 6 has four clamping tables 601 uniformly arranged around the circumferential edge thereof. The clamping tables can be clamped into the corresponding grooves on the automatic machine, and the side wall of the clamping table is an arc surface matched with the inner wall of the groove on the automatic machine. The rotating disc further has two first lugs 602 arranged in parallel on one side edge thereof. Coaxial guide through holes 603 for the positioning pin 4 to pass through are arranged on the two first lugs, and the axis of the guide through hole is perpendicular to the center axis of the rotating disc. A locking-unlocking assembly mounting hole 604 is further arranged on the first lug, and the axis of the locking-unlocking assembly mounting hole is perpendicular to the axis of the guide through hole. The locking-unlocking assembly is mounted in the locking-unlocking assembly mounting hole. The locking-unlocking assembly can automatically lock the positioning pin after the positioning pin 4 is butted against the mounting hole on the automatic machine, so as to ensure the reliable connection with the automatic machine. The locking-unlocking assembly can also release the locking of the positioning pin, so that the positioning pin 4 and the mounting hole on the automatic machine are automatically separated.

[0059] With reference to Figure 3 The positioning pin 4 is a rotary shaft type component. One end of the positioning pin 4 has a clamping groove 401 arranged along the axial direction thereof from the end surface. The end of the connecting rod 8 connected with the positioning pin is arranged in the clamping groove 401 of the positioning pin and is hingedly connected with the positioning pin through a connecting pin 5. In order to make the two end surfaces of the two positioning pins close to each other contact with each other when the positioning pin 4 is separated from the mounting hole on the automatic machine under the pulling action of the connecting rod, the length of the positioning pin 4 is equal to the radius of the rotating disc 6. A blind hole 402 is arranged on the side wall of the other end of the positioning pin 4 in the radial direction, which is used for locking cooperation with the locking pin 10. Specifically, the width of the clamping groove of the positioning pin 4 is equal to the thickness of the end of the connecting rod 8 connected with the positioning pin. It should be noted that the width direction of the clamping groove is perpendicular to the axis direction of the blind hole on the positioning pin.

[0060] With reference to Figure 4 The connecting rod 8 is a plate component with semicircular ends. The top surface of one end of the connecting rod body connected with the positioning pin 4 has a first cylindrical boss 801. The thickness of the end with the first cylindrical boss is equal to the width of the clamping groove of the positioning pin. The width direction of the clamping groove is perpendicular to the axis direction of the blind hole 402 on the positioning pin. Specifically, the thickness of the connecting rod body is equal to the thickness of the first cylindrical boss 801, which not only ensures the reliable connection between the connecting rod and the positioning pin, but also further reduces the weight of the connecting rod.

[0061] With reference to Figure 5The push rod 3 comprises a rectangular shaft 301, a cylindrical shaft 302 and a rectangular block 303 arranged coaxially in sequence. The push rod 3 is provided with a first shaft shoulder 304 and a second shaft shoulder 305 arranged coaxially, the first shaft shoulder is located at the joint of the rectangular shaft and the cylindrical shaft of the push rod, the large spring 7 is sleeved on the rectangular shaft of the push rod, and the end face abuts against the end face of the first shaft shoulder. The second shaft shoulder is arranged between the cylindrical shaft and the rectangular block of the push rod, and is used for mounting and positioning the rotating arm 12 and the rectangular block of the push rod. The end of the rectangular shaft of the push rod is provided with two second lugs 306 parallel to each other, and one end of the connecting rod 8 connected with the push rod 3 is located between the two second lugs 306 and is hinged through a connecting pin 5. The rectangular shaft of the push rod is used for cooperating with the center hole of the rotating disc, and plays a guiding role when the push rod 3 slides in the center hole of the rotating disc. A first screw hole 307 is formed in the rectangular block along the radial direction of the push rod, and is used for fixedly connecting the push rod and the handle assembly. When the connecting assembly is in a non-working state (i.e. when the positioning pins are completely separated from the mounting hole of the automatic machine), the large spring 7 mounted on the rectangular shaft of the push rod is compressed under the extrusion of the end of the rotating disc, and pushes the push rod back along the axial direction of the push rod (towards the direction of the rectangular block of the push rod), so that the push rod 3 can drive the connecting rod 8 to move back to reset until the ends of the two positioning pins are in contact.

[0062] Referring to Figure 6 and Figure 7 , specifically, the rotating disc 6 is in a disc structure, the top surface of the four clamping tables 601 uniformly arranged on one side of the rotating disc 6 is a plane, and two first lugs 602 parallel to each other are respectively located in two symmetrical gaps between the clamping tables. The other two symmetrical gaps between the clamping tables have a fan-shaped notch, so as to avoid interference between the rotating disc and other parts of the automatic machine when the clamping tables 601 are clamped with the grooves of the automatic machine. The center hole of the rotating disc is a square hole, which is used for cooperating with the rectangular shaft of the push rod 3. The center of the side of the rotating disc away from the clamping tables has a second cylindrical boss extending outward along the axial direction; the ends of the large spring 7 abut against the end faces of the first shaft shoulder 304 of the push rod and the second cylindrical boss 605 of the rotating disc, respectively. The mounting hole 604 of the locking-unlocking assembly on the first lug of the rotating disc 6 is a stepped hole, and the large hole of the stepped hole is in communication with the guide hole on the first lug 602. Specifically, the first lug 602 can be inserted into the inner hole 1501 of the automatic machine, and the side wall of the first lug 602 is an arc surface matched with the inner wall surface of the inner hole 1501 of the automatic machine.

[0063] The locking-unlocking assembly comprises a small spring 9, a locking pin 10 and a pull ring 11. Referring to Figure 8The locking pin 10 comprises coaxially connected large shaft section and small shaft section, the large shaft section matches with the large hole of the stepped hole on the first lug, and can slide along the large hole of the stepped hole; the small shaft section matches with the small hole of the stepped hole on the first lug, and can slide along the small hole of the stepped hole. And the small shaft section protrudes out of the stepped hole, the rod body of the small shaft section away from the large shaft section has a radial mounting hole for mounting the pull ring 11. The pull ring 11 is used for pulling the locking pin outward, so that the locking pin 10 can be pulled out of the blind hole on the side wall of the positioning pin 4 to release the locking of the positioning pin. Specifically, the side wall of the small shaft section has two symmetrical planes at the position where the radial mounting hole is arranged, facilitating the installation of the pull ring 11.

[0064] The small spring 9 is sleeved on the small shaft section of the locking pin 10, and the two ends of the small spring 9 are limited between the stepped surface of the large shaft section of the locking pin 10 and the stepped surface of the stepped hole on the first lug, and after the locking pin 10 releases the locking of the positioning pin 4, the small spring 9 is in a compressed state, so that when the positioning pin 4 is clamped into the installation through hole of the automatic machine under the action of the push rod 3 and the connecting rod 8, and the blind hole on the side wall of the positioning pin is gradually coaxial with the installation through hole of the locking-unlocking assembly on the first lug of the rotating disc 6, the locking pin 10 can be inserted into the blind hole on the side wall of the positioning pin 4 under the elastic force of the small spring 9, realizing the automatic locking of the positioning pin.

[0065] Referring to Figure 9 The handle assembly comprises a handle sleeve 14, a rotating arm 12 and a handle rod 13 vertically connected with one end of the rotating arm 12, and specifically, the handle rod 13 is connected with the rotating arm 2 in a threaded manner. The other end of the rotating arm 12 has a radially arranged square through hole 1201 on the side wall, which cooperates with the rectangular block of the push rod 3. The other end of the rotating arm 12 has a second screw hole 1202 opened along the axial direction of the rotating arm, and the second screw hole and the first screw hole arranged on the rectangular block of the push rod are used to fixedly connect the rectangular block of the push rod with the rotating arm 12 through a screw. The handle sleeve 14 is coaxially sleeved on the handle rod 13, and the surface of the handle sleeve 14 is knurled to increase the friction between the operator's hand and the handle sleeve, ensuring the reliability when the operator rotates the handle rod.

[0066] The installation process of the automatic machine connecting rod type hand rotating device is as follows:

[0067] The installation of the locking-unlocking assembly: the end of the locking pin 10 penetrates the small spring 9 and is coaxially installed in the stepped hole on the first lug of the rotating disc 6, at this time, under the abutting action of the arc-shaped side wall of the positioning pin, the large shaft section of the locking pin 10 compresses the small spring 9 and pushes the small shaft section of the locking pin 10 to protrude backward; the pull ring 11 is installed on the small shaft section of the locking pin 10.

[0068] The installation of the connecting assembly: install the big spring 7 coaxially on the rectangular shaft of the push rod 3, then pass the end of the rectangular shaft of the push rod 3 through the square hole in the center of the rotating disc 6, and compress the big spring 7 by the second cylindrical boss of the rotating disc. Then install two connecting rods between the second lugs of the push rod 3, and connect the one end of the connecting rods with the second lugs by a connecting pin. Finally, install the two positioning pins 4 coaxially in the guide through holes on the rotating disc 6, insert the end of the connecting rods with the first cylindrical boss into the corresponding card slot of the positioning pin respectively, and connect the connecting rods with the corresponding positioning pins by the connecting pin 5 respectively.

[0069] The installation of the handle assembly: install the handle sleeve 14 coaxially on the handle rod 13, and connect the handle rod 13 with the rotating arm 12 by screwing.

[0070] The assembly of the connecting assembly and the handle assembly: install the rectangular block of the push rod 3 into the square through hole of the rotating arm 12, and fix the push rod with the rotating arm by screwing.

[0071] After assembly, as shown in Figure 10 , at this time, each component of the manual rotary device of the present application is in a non-working state.

[0072] When in use, align the four card platforms 601 on the rotating disc of the manual rotary device of the present application with the four grooves on the automatic machine shell 15, push the push rod 3, and the card platform 601 is clamped into the groove on the automatic machine shell. The first lug 602 on the rotating disc is inserted into the inner hole 1501 of the automatic machine shell, and the push rod 3 compresses the big spring 7 while acting on the two positioning pins 4 through the two connecting rods respectively. The two positioning pins 4 respectively extend outwardly through the two symmetrically arranged guide through holes. When the positioning pins extend into the mounting through hole of the automatic machine shell and the blind hole on the side wall of the positioning pin 4 is aligned with the stepped hole on the first lug of the rotating disc, the locking pin 10 is clamped into the blind hole on the side wall of the positioning pin 4 under the pushing action of the pin spring 9 on the locking pin, and the positioning pin is locked in the mounting through hole of the automatic machine. At this time, the card platform is also clamped into the cylindrical groove on the automatic machine. Refer to Figure 11 , at this time, the manual rotary device of the present application is in a working state, and the manual rotary device is reliably connected with the automatic machine. Hold the handle sleeve and rotate the handle rod 13, and the automatic machine is driven to rotate by the connecting assembly.

[0073] When the manual rotary device of the present application needs to be removed after use, pull the pull ring 11 installed on the small shaft segment of the locking pin 10 to release the locking of the positioning pin 4 by the locking pin. The big spring 7 automatically rebounds, and the push rod 3 moves backward (in the direction of the installation position of the handle assembly) under the action of the big spring 7. At the same time, the push rod 3 pulls the connecting rod 8 and the positioning pin 4 connected with the connecting rod 8 to automatically disengage from the mounting through hole of the automatic machine. When the tail ends of the two positioning pins contact and implement the limiting action, the push rod stops moving, and at this time the positioning pin is completely disengaged from the mounting through hole of the automatic machine. Release the pull ring, and the locking pin 10 abuts against the side wall of the positioning pin. The manual rotary device of the present application returns toFigure 10 The manual rotating device is directly removed from the recess of the automatic machine in the non-working state. Finally, the manual rotating device is directly removed from the recess of the automatic machine in the non-working state.

[0074] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements shall be covered within the protection scope of the present application.
