For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0048] As Figures 1-18 shown:

[0049] The application provides a manual pump semi-automatic assembly production equipment embodiment,

[0050] As Figures 1-18 shown, comprising rack 10, the inside of rack 10 is provided with first assembly station 11 and second assembly station 12, second assembly station 12 is provided with lifting mechanism 16, lifting mechanism 16 is provided with telescopic mechanism 18, the extension end of telescopic mechanism 18 is provided with tightening assembly 19, tightening assembly 19 includes shell 21, the inside of shell 21 is slidably provided with several movable plates 27, the inside of movable plate 27 is rotatably provided with rotating rod 25, the lower end of rotating rod 25 is provided with knob head 39, the lower part of knob head 39 is provided with limiting groove 40, the inside of limiting groove 40 is slidably provided with screwdriver 41, the inside of shell 21 is provided with several frame bodies 28, the lower side of movable plate 27 is provided with inverted quadrangular platform 29, the inside of frame body 28 is provided with rubber frame 31, the opposite two sides of quadrangular platform 29 are respectively provided with one protrusion 30, the opposite two sides of rubber frame 31 are respectively provided with one recess 32, the lower side of recess 32 is provided with cylinder 33, the inside of cylinder 33 is slidably provided with T-shaped rod 34, a plurality of tension springs 35 are connected between the upper side of cylinder 33 and the lower end of protrusion 30, the other opposite two sides of quadrangular platform 29 are provided with several pairs of placing grooves 65, and damping assembly 55 is arranged in placing groove 65.

[0051] Specific implementation, because the inner wall of movable plate 27 is in rotational contact with annular groove 66, rotating rod 25 cannot drive movable plate 27 to rotate, and rotating rod 25 moves downward to drive movable plate 27 to move downward, so that movable plate 27 slides downward in shell 21. Movable plate 27 moves downward to drive quadrangular platform 29 to move downward into frame body 28. Quadrangular platform 29 moves downward to drive several pairs of damping assemblies 55 to move downward into frame body 28, so as to utilize several pairs of damping assemblies 55 to enter frame body 28 in sequence to perform damping and buffering, which can gradually increase the area of the opposite two sides of rubber frame 31 respectively in contact with several pairs of damping assemblies 55, so as to improve the damping effect of several pairs of damping assemblies 55 on the stable rotation of rotating rod 25 downward, and avoid the shaking of rotating rod 25.

[0052] In the process of tightening the two screws or multiple screws simultaneously, the tightening assembly 19 may not be aligned, which makes it difficult to tighten the screw, resulting in screw jamming. At this time, the screw jamming causes the knob head 39 and the rotating rod 25 to stop rotating. Due to the force decomposition characteristics of the tooth surface caused by the helix angle, the first helical gear 24 rotates to cooperate with the second helical gear 26 and the rotating rod 25 stops rotating, so that the second helical gear 26 and the rotating rod 25 are subjected to an upward axial force, thereby moving the rotating rod 25 and the knob head 39 upward. The upward movement of the knob head 39 drives the screw upward by the magnetism of the screwdriver 41, so as to realign the screw for tightening. At this time, the screw is disengaged from the jamming condition, the first helical gear 24 drives the second helical gear 26 and the rotating rod 25 to rotate, the rotating rod 25 drives the knob head 39 to rotate, and the knob head 39 drives the screw to rotate, thereby re-tightening the screw.

[0062] In the initial state, the tension spring 35 is in a tension state and has elasticity, and under the action of the elasticity of the tension spring 35, the movable plate 27 and the rotating rod 25 can be subjected to a downward pulling force.

[0063] The specific use method of the present application is as follows:

[0064] In the process of assembling the manual pump, in order to ensure that the pump body structure is stable and sealed reliably, the tightening assembly 19 in the semi-automatic assembly production equipment of the manual pump is used to install a plurality of screws on the shell 21 of the manual pump, so as to tighten the shell 21 of the manual pump.

[0065] Firstly, the staff performs semi-automatic assembly of the manual pump on the first assembly station 11, and after the manual pump is assembled, the staff places the manual pump on the workbench 15 in the second assembly station 12, and clamps and fixes the shell 21 of the manual pump by using the workbench 15. And the end cover 22 of the manual pump is installed on the shell 21 of the manual pump, at this time, the end cover 22 of the manual pump needs to be fixed on the shell 21 of the manual pump by using the screw.

[0066] Secondly, the control system controls the telescopic mechanism 18 to drive the tightening assembly 19 to move horizontally, so that the two knob heads 39 in the tightening assembly 19 correspond to the two screws on the end cover 22 of the manual pump up and down. The lifting mechanism 16 drives the telescopic mechanism 18 and the tightening assembly 19 to move stably downward, the tightening assembly 19 moves downward to drive the two knob heads 39 to move downward, so that the upper ends of the two screws enter the two limiting grooves 40 respectively, and the lower end of the screwdriver 41 contacts the cross groove on the upper end of the screw.

[0067] Then, the step motor 23 drives the first helical gear 24 to rotate, since the first helical gear 24 is engaged with the two second helical gears 26, the rotation of the first helical gear 24 drives the two second helical gears 26 and the rotating rods 25 to rotate. The rotation of the two rotating rods 25 drives the two knob heads 39 to rotate, and the lower end of the screwdriver 41 corresponds to the cross groove on the upper end of the screw, so that the rotation of the two knob heads 39 drives the two screws to rotate. And when the first helical gear 24 is engaged with the second helical gear 26, the tooth surface stress decomposition characteristics caused by the helix angle, the second helical gear 26 and the rotating rod 25 are subjected to axial force and under the action of the elasticity of the tension spring 35, the rotating rod 25 can rotate and move axially downward, so as to stably screw the screw into the shell 21 of the manual pump, so as to install the end cover 22 of the manual pump on the shell 21 of the manual pump.

[0068] Meanwhile, since the inner wall of the movable plate 27 is in rotational contact with the annular groove 66, the rotation of the rotating rod 25 cannot drive the movable plate 27 to rotate, and the downward movement of the rotating rod 25 drives the movable plate 27 to move downward, so that the movable plate 27 slides downward in the shell 21. The downward movement of the movable plate 27 drives the quadrangular frustum 29 to move downward into the frame 28. The downward movement of the quadrangular frustum 29 drives the plurality of pairs of damping assemblies 55 to move downward into the frame 28, so as to gradually increase the areas of the opposite two side walls of the rubber frame 31 in contact with the plurality of pairs of damping assemblies 55, so as to improve the damping effect of the plurality of pairs of damping assemblies 55 on the rotating rod 25 during the stable downward rotation, and avoid the shaking of the rotating rod 25.

[0069] Meanwhile, the downward movement of the movable plate 27 drives the quadrangular frustum 29 to move downward, and the downward movement of the quadrangular frustum 29 drives the damping assembly 55 to move downward. The side of the damping plate 57 is in contact with the inner wall inclined surface of the rubber frame 31, and the distance between the outer wall side of the quadrangular frustum 29 and the inner wall side of the rubber frame 31 gradually decreases during the downward movement of the damping assembly 55, so as to compress the damping assembly 55 by the quadrangular frustum 29 and the rubber frame 31. The damping assembly 55 is compressed, the distance between the damping plate 57 and the shell 56 is reduced, the damping plate 57 moves to push the two sliders 58 away from each other by the two connecting plates 61, and the two sliders 58 are away from each other to compress the two damping springs 62 to generate elastic force, so as to ensure that the damping assembly 55 has good damping and buffering effect during the downward movement of the rotating rod 25. The distance between the damping plate 57 and the shell 56 is reduced to be fixed by the mounting plate 63, so as to compress the damper 64 to generate elastic force, which can improve the damping and buffering effect of the damping assembly 55 on the rotating rod 25 under the action of the elastic force of the damper 64, avoid the shaking of the rotating rod 25 during the screw tightening process, and improve the efficiency of the screw tightening. The two sliders 58 are in sliding contact with the outer wall of the guide rod 59, which can guide the two sliders 58 by the guide rod 59, so as to stably compress the two damping springs 62 for damping and buffering.

[0070] Then, the movable plate 27 moves downward to drive the quadrangular prism 29 and the two protrusions 30 to move downward, the two protrusions 30 move downward to drive the two T-shaped rods 34 to move downward, the T-shaped rods 34 move downward to extrude the solution in the cylinder 33 through the inside of the T-shaped rods 34 and the first connecting channel 36 to the movable plate 27, and the solution in the movable plate 27 is transported to the first hydraulic cavity 38 through the second connecting channel 37. The solution in the first hydraulic cavity 38 pushes the first pressing plate 46 to move downward, the first pressing plate 46 moves downward to drive the several pairs of guide plates 47 to move downward, and since the lower end of each pair of guide plates 47 is in sliding contact with the upper end of one pair of sliding plates 42, the movement of the pair of guide plates 47 guides the pair of sliding plates 42 to move downward, so that the pair of sliding plates 42 moves closer to each other. The two sliding plates 42 move away from each other to drive the two rubber protrusions 44 to move closer to each other, so that the two rubber protrusions 44 are fully inserted into the two clamping grooves 43, respectively, and the several pairs of clamping grooves 43 and the several pairs of rubber protrusions 44 can be used to limit and fix the knob head 39 at the lower part of the rotating rod 25, so as to avoid the situation that the knob head 39 is separated from the lower part of the rotating rod 25 during the tightening of the screw. At the same time, the movement of the first pressing plate 46 downward compresses the second spring 48 to generate elastic force, so that the first pressing plate 46 can be reset under the action of the elastic force of the second spring 48.

[0071] At the same time, after the several pairs of sliding plates 42 move radially inward to fully clamp and fix the upper part of the knob head 39, the electromagnetic valve 50 is opened, the solution in the first hydraulic cavity 38 is transported to the second hydraulic cavity 51 through the telescopic pipe 49, and the solution in the second hydraulic cavity 51 pushes the second pressing plate 52 to slide in the second hydraulic cavity 51. The second pressing plate 52 moves downward to drive the elastic rod 53 to move downward, and since the lower end of the elastic rod 53 is connected with the screwdriver 41, the elastic force generated by the elastic rod 53 is used to extrude the elastic rod 53 to generate elastic force, and the elastic force generated by the elastic rod 53 acts on the screwdriver 41, so as to fully insert the screwdriver 41 into the cross groove at the upper end of the screw, thereby improving the efficiency of tightening the screw by the knob head 39.

[0072] Finally, the tightening assembly 19 in the process of tightening two screws or multiple screws at the same time, there are some screws misaligned, resulting in the tightening assembly 19 difficult to tighten the screw, resulting in the screw jam. At this time, the screw jam causes the knob head 39, the rotating rod 25 to stop rotating, due to the helix angle resulting in the force decomposition characteristics of the tooth surface, the first helical gear 24 rotates the second helical gear 26, the rotating rod 25 stops rotating, so that the second helical gear 26, the rotating rod 25 is subjected to the axial force upward, so that the rotating rod 25, the knob head 39 moves upward. The knob head 39 moves upward uses the magnetism of the screwdriver 41 to drive the screw to move upward, so as to be able to make the screw realign and tighten. At this time, the screw is out of the jam, the first helical gear 24 drives the second helical gear 26, the rotating rod 25 to rotate, the rotating rod 25 drives the knob head 39 to rotate, the knob head 39 drives the screw to rotate, and the screw is re-tightened. The tightening assembly 19 can automatically adjust the screw, avoid the influence of the partial screw jam on the normal tightening of the other screws, and improve the efficiency of the tightening assembly 19 on the tightening of the screws. Wherein, when the movable plate 27, the rotating rod 25 moves upward to drive the screw to align, the second hydraulic chamber 51 disappears under the action of the solution pressure, the second pressure plate 52, the elastic rod 53, and the screwdriver 41 are driven to move upward under the action of the third spring 54. The screwdriver 41 moves upward to make the upper end of the screw fully enter the limiting groove 40, and the limiting groove 40 can be used to limit the screw to align, which is beneficial to improve the efficiency of the screw alignment and the efficiency of the screw re-tightening.
