[0002] The jack is a tool for lifting heavy objects. During the production process of the jack, its various parts need to be assembled in an assembly line. One of the assembly processes requires moving the steel balls to the base welded parts for assembly and installation. During this process, a steel ball feeding device is required to feed the steel balls. At present, the main method for feeding steel balls is for the robot to use negative pressure to absorb the steel balls, and then transfer the steel balls to the base welded parts for feeding. Before feeding, the steel balls are usually placed in a vibrating tray. The steel balls are moved to the robot using the flow channel of the vibrating tray, and then the robot absorbs them. Then, when the steel balls are concentrated in the vibrating tray, the steel balls rub against each other during the accumulation process, so that the surface of the steel balls will absorb dust due to static electricity. When the steel balls with dust attached are assembled into the base welded parts, the wear of the steel balls will be accelerated, affecting their service life.

[0003] After searching, the Chinese patent application number 202223606773.3 discloses a steel ball feeding device for casters, including a steel ball placement box, a steel ball transferring bracket arranged above the steel ball placement box, a steel ball transverse moving mechanism arranged on the steel ball transferring bracket, a steel ball vertical moving mechanism connected to the steel ball transverse moving mechanism, and a steel ball transferring head connected to the steel ball vertical moving mechanism; a steel ball pushing head is arranged in the steel ball placement box, and a plurality of steel ball grooves for placing steel balls are arranged on the top surface of the steel ball pushing head.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1.

[0029] 3. The present invention generates negative pressure by providing a negative pressure ion fan. The adsorption head absorbs the steel balls during the suction process, and exhausts the air by using the nozzle and the connecting pipe. When the steel balls in the arc-shaped shell rotate to a position close to the nozzle, the connecting pipe is used to blow away the dust on the outer wall of the spherical surface of the steel balls.

[0030] 4. The present invention provides an arc-shaped rack and a bevel gear to enable the rotating cylinder and the adjusting cylinder to rotate relative to each other, and provides a coil spring to ensure that the rotating cylinder and the adjusting cylinder are automatically reset when the arc-shaped rack and the bevel gear are disengaged from each other.

[0031] 5. The present invention limits the single feeding amount of the steel balls by providing the material hole and the outlet hole, and facilitates the circulation of the steel balls into the arc shell. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The present invention provides a technical solution:

[0045] Embodiment 1:

[0049] Adjustment tube 49: It is welded to one end of the air pipe 45, and the outer wall of the adjustment tube 49 is provided with a second air hole 50, and one end of the adjustment tube 49 is threadedly connected with the adsorption head 41;

[0050] Rotating cylinder 39: It is rotatably connected to the outer circumferential wall of the adjusting cylinder 49, and the outer circumferential wall of the rotating cylinder 39 is provided with an air hole 48;

[0051] Shell 46: It is welded to one end of the rotating cylinder 39, and a coil spring 47 is fixed between the inner wall of the shell 46 and the outer wall of the circumference of the air pipe 45 by means of a clamping connection;

[0052] Gear 2 38: It is fixed to the outer wall of one side of the rotating cylinder 39 through a support;

[0053] The clamping plate 31 is welded to the outer wall of the circumference of the air pipe 45, and the outer wall of one side of the clamping plate 31 is rotatably connected to a lead screw 32, and one end of the lead screw 32 is fixed with a gear 1 37 meshing with a gear 2 38 by a pin;

[0054] Limiting rod 42: welded to the outer wall of one side of the clamping plate 31;

[0055] The slide plate 34 is slidably connected to the inner wall of the through hole opened on the surface of the card plate 31, and a nut matching the outer diameter of the lead screw 32 is embedded on the surface of the slide plate 34;

[0056] Rotating column 27: It is rotatably connected to one end of the slide plate 34, and a bent rod 44 is welded to the side wall of the rotating column 27;

[0057] The annular sheet 24 is welded to one end of the curved rod 44, and arc-shaped shells 26 are welded to both sides of the annular sheet 24;

[0058] Conical spring piece 25: It is fixed to the side wall of the annular piece 24, and the inner surface of the conical spring piece 25 is bonded with a wiping cotton 43;

[0059] Vertical plate 33: It is welded to the top of the card plate 31, and a receiving rod 35 is welded to the outer wall of one side of the vertical plate 33, and a contact head 23 is welded to one end of the receiving rod 35, and a slide plate 34 is slidably connected to the outer wall of the receiving rod 35;

[0060] The side wall of the rotary joint 13 is connected to the negative pressure component;

[0061] When it is necessary to load the steel balls, the steel balls are first sucked by negative pressure. During the suction process, the suction head 41, the adjusting cylinder 49, the air pipe 45, the middle seat 30 and the hollow column 14 are connected to each other, so that one end of the suction head 41 sucks the steel balls by negative pressure, and the steel balls are transferred to the base welding parts during the suction process. In the initial stage, the air hole 2 50 on the outer wall of the adjusting cylinder 49 and the air hole 1 48 on the outer wall of the rotating cylinder 39 are in a relatively misaligned position, so that the negative pressure is only concentrated on the end of the suction head 41. After the steel balls are sucked to the base welding parts by negative pressure, the rotating cylinder 39 is driven to rotate relative to the outer wall of the adjusting cylinder 49, so that the air hole 1 48 gradually moves to the position overlapping with the air hole 2 50. When the air hole 2 50 and the air hole 1 48 overlap, the air pressure inside and outside the adjusting cylinder 49 is the same. At this time, the end of the suction head 41 loses the negative pressure suction ability for the steel balls, so that the steel balls fall into the base welding parts under the action of their own gravity to achieve loading.

[0062] Before the steel ball is loaded, dust particles and other impurities will adhere to its surface. If the surface is not cleaned, when it is assembled between the base welding parts, it will affect the performance of the base welding parts and accelerate the wear of the steel ball. Therefore, the steel ball is placed through the arc shell 26. In this embodiment, the number of arc shells 26 is preferably two groups. During the relative rotation between the rotating cylinder 39 and the adjusting cylinder 49, the rotating cylinder 39 synchronously drives the gear 2 38 to rotate. During the rotation, the gear 2 38 obtains the rotation of the gear 1 37 and the lead screw 32. In this process, the guiding and limiting effect of the limiting rod 42 is used to make the slide plate 34 slide along the connecting block 36. The outer diameter of the gear 2 38 is larger than the outer diameter of the gear 1 37. Therefore, under the premise of the same linear speed, there is a difference in angular velocity, that is, when the gear 2 38 rotates a smaller angle, the gear 1 37 rotates a larger angle, and the slide plate 34 moves laterally. During the movement, the annular piece 24 and the conical spring piece 25 are driven to move laterally. During the movement, the slide plate 34 is slidably connected to the outer wall of the accommodating rod 35. When the annular piece 24 and the conical spring piece 25 slide along the outer wall of the steel ball spherical surface, the contact head 23 is used to limit the steel ball, ensuring that the annular piece 24 and the conical spring piece 25 slide along the outer wall of the steel ball spherical surface, and the steel ball remains stable. The conical spring piece 25 has a certain elasticity, so that the conical spring piece 25 ensures that the wiping cotton 43 and the outer wall of the steel ball spherical surface remain in contact during the movement. Multiple conical spring pieces 25 are in an outwardly expanded state during this process, and the wiping cotton 43 wipes the outer wall of the steel ball spherical surface to reduce dust accumulation on the surface of the steel ball. When the annular piece 24 is completely detached from the steel ball spherical surface, the steel ball enters another arc shell 26 from one of the arc shells 26 to achieve the cleaning operation of the steel ball.

[0063] Furthermore, an arc-shaped rack 21 is fixed to the top outer wall of the base 1 through a mounting frame, and a bevel gear 40 used in conjunction with the arc-shaped rack 21 is fixed to the circumferential outer wall of the rotating cylinder 39 through a pin;

[0064] When the hollow column 14 rotates along the rotary joint 13, during this process, the bevel gear 40 gradually approaches the position of the arc-shaped rack 21. When the arc-shaped rack 21 and the bevel gear 40 are meshed, the arc-shaped rack 21 drives the bevel gear 40 and the rotating cylinder 39 to rotate along the circumferential outer wall of the adjusting cylinder 49, so that after the air hole 2 50 and the air hole 1 48 overlap, the steel balls sucked by the end of the adsorption head 41 are loaded. By providing a coil spring 47, when the arc-shaped rack 21 and the bevel gear 40 are disengaged, it is ensured that the rotating cylinder 39 and the adjusting cylinder 49 are reset, thereby realizing periodic loading of the steel balls.

[0065] Furthermore, a bracket 11 is fixed to the top outer wall of the base 1 by bolts, and a motor 12 is fixed to the top inner wall of the bracket 11 by bolts, and pulleys are fixed to the output end of the motor 12 and the circumferential outer wall of the hollow column 14 by pins, and a belt is used to transmit the power between the two pulleys;

[0066] The motor 12 drives the hollow column 14 to rotate by utilizing the transmission effect of the pulley and the belt, so that the steel balls are fed by the rotation.

[0067] Furthermore, a guide rod 29 is fixed to the side wall of the intermediate seat 30 by screws, and a limit head 28 is welded to one end of the guide rod 29, and an annular groove 22 used in conjunction with the limit head 28 is provided on the circumferential outer wall of the rotating column 27;

[0068] When the slide plate 34 moves laterally, the limit head 28 is used to guide the moving path of the annular groove 22, so that the rotating column 27 also rotates during the lateral movement. When the steel balls are cleaning, the arc shell 26 is in the process of rotating. When the steel balls are cleaned, the arc shell 26 rotates to a certain angle, so that the steel balls fall from the arc shell 26 due to gravity, thereby realizing the extraction of the steel balls.

[0069] Furthermore, a conical material tray 8 is fixed to the top outer wall of the base 1 by bolts, and a connecting rod 9 is welded to the side wall of the conical material tray 8, and a conical funnel 10 is welded to one end of the connecting rod 9;

[0070] When the steel balls are in the process of cleaning, the arc shell 26 gradually approaches the position of the conical funnel 10. When the arc shell 26 rotates a certain angle, the steel balls fall into the conical funnel 10 and finally fall into the conical material tray 8. When the adsorption head 41 rotates to above the conical material tray 8, the negative pressure is used to absorb the steel balls in the conical material tray 8 to realize the loading of the steel balls.

[0071] Further, the negative pressure assembly includes a negative pressure ion fan 7 and a connecting pipe 20, the negative pressure ion fan 7 is fixed to the top outer wall of the base 1 by screws, the connecting pipe 20 is connected between the negative pressure ion fan 7 and the rotary joint 13, one end of the negative pressure ion fan 7 is connected to a connecting pipe 19 through a joint, and one end of the connecting pipe 19 is threadedly connected to a nozzle 18;

[0072] Negative pressure is generated by providing a negative pressure ion fan 7, and the steel balls are absorbed during the suction process of the adsorption head 41, and the exhaust is performed by the nozzle 18 and the connecting pipe 19. When the steel balls in the arc shell 26 rotate to a position close to the nozzle 18, the connecting pipe 19 is used to blow the outer wall of the spherical surface of the steel balls. During the blowing process, the negative pressure ion fan 7 effectively removes static electricity and speeds up the cleaning effect of the dust on the surface of the steel balls. The cleaning effect of the steel balls is improved by cooperating with the wiping cotton 43. In addition, when the connecting pipe 19 is blowing the steel balls, the conical spring piece 25 limits the steel balls to prevent the steel balls from falling from the arc shell 26 under the action of wind.

[0073] When the present embodiment is in use, the steel ball is first placed in the arc shell 26, and then the transmission effect of the pulley and the belt is utilized to make the motor 12 drive the hollow column 14 to rotate. During the rotation process, the hollow column 14 drives the arc shell 26 to move in the direction close to the conical funnel 10, and at the same time, the bevel gear 40 moves in the direction close to the arc rack 21. When the bevel gear 40 moves to mesh with the arc rack 21, the arc rack 21 is utilized to drive the bevel gear 40 to rotate, so that the rotating cylinder 39 rotates relative to the adjusting cylinder 49. During the rotation process, the rotating cylinder 39 drives the second gear 38 to rotate. During the rotation process, the second gear 38 drives the first gear 37 and the lead screw 32 to rotate. The annular groove 22 and the rotating column 27 are utilized to make the arc shell 26 rotate itself during the lateral movement. During the lateral movement of the arc shell 26, the annular sheet 24 is moved to the adjusting cylinder 49. The outer wall of the spherical surface of the steel ball is wiped. When the steel ball is wiped, the arc shell 26 gradually rotates to the top of the conical funnel 10. After rotating a certain angle, the arc shell 26 allows the steel ball to fall into the conical funnel 10 and finally fall into the conical material tray 8. Then the output end of the motor 12 is reversed, so that the adsorption head 41 moves toward the direction of the conical funnel 10. When the adsorption head 41 moves to the top of the conical material tray 8, the negative pressure component is used to make the adsorption head 41 absorb the steel ball through negative pressure. Then the output end of the motor 12 rotates in the opposite direction again so that the adsorption head 41 drives the absorbed steel ball to move toward the arc rack 21. When the arc rack 21 and the bevel gear 40 are meshed again, when the air hole 48 opened on the circumferential outer wall of the rotating cylinder 39 rotates to coincide with the air hole 2 50 opened on the circumferential outer wall of the adjusting cylinder 49, the steel ball falls into the base welding part under the action of its own gravity for loading.

[0074] Embodiment 2:

[0076] By connecting the feed tube 4 and the vibrating feed tray, the vibrating feed tray is used to make the steel balls enter the feed tube 4 in an arranged manner in sequence. When the material hole 3 on the distribution tray 2 is rotated to a position directly opposite to one end of the feed tube 4, the steel balls fall into the material hole 3. When in use, the discharge amount of a single steel ball is limited by the material hole 3. After the steel balls enter the material hole 3, the distribution tray 2 drives the material hole 3 to rotate so that the steel balls move toward the direction close to the discharge hole 17. When the material hole 3 and the discharge hole 17 overlap with each other, the steel balls pass through the material hole 3 and the discharge hole 17 and fall into the arc shell 26 for cleaning.
