Description

Technical Field

[0001] The utility model relates to the field of processing tools, in particular to a feeding mechanism for nut tapping. Background Technique

[0002] At present, the Chinese utility model with the publication number of CN211539806 discloses a feeding mechanism for nut tapping. Although this feeding mechanism can push nuts through a cylinder and a push plate, there are still other problems in the use process. For example, it does not have a height adjustment function. During use, the components need to be fixed on the tapping machine with screws. After the components are fixed, the height of the discharge port needs to match the height of the fixture on the tapping machine. If it is higher or lower than the fixture, it will affect the feeding effect, and the flexibility is poor. Moreover, the single-push quantity cannot be adjusted. The tapping machine includes two types: one-out-one and one-out-two, that is, one nut or two nuts can be tapped at a time. However, since the component can only push one nut at a time, it is not applicable to the one-out-two type of tapping machine for processing, and the adaptability is low. In order to solve the above problems, we propose a feeding mechanism for nut tapping. Content of the Utility Model

[0003] The purpose of the utility model is to provide a feeding mechanism for nut tapping, which solves the problems that the existing feeding mechanism does not have a height adjustment function and cannot adjust the single-push quantity.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions: A feeding mechanism for nut tapping includes a fixed seat. One side of the fixed seat is welded through and provided with a stacking frame. One side and the front of the fixed seat are respectively bolted through and provided with a first cylinder and a second cylinder. The output ends of the first cylinder and the second cylinder are respectively installed with a first push plate and a second push plate. A slot is opened on the back of the second push plate, and a partition plate is slidably clamped inside the slot. The bottom of the fixed seat is symmetrically welded with fixing plates. A U-shaped base is arranged at the bottom of the fixed seat. Threaded rods are welded on the opposite sides of the two fixing plates. Sliding grooves are opened on the front and back of the U-shaped base, and fixing nuts are threadedly connected to the surfaces of the threaded rods.

[0005] By adopting the above technical solutions, it can have a height adjustment function, so that it can fit the surfaces of fixtures with different thicknesses, avoid obstacles when the nuts are pushed out, have good flexibility, and at the same time can adjust the single-push quantity, with simple and labor-saving operation, be applicable to different types of tapping machines for use, and have high practicability.

[0006] The utility model is further arranged as follows: Anticorrosive coatings are applied to the surfaces of the fixed seat and the stacking frame.

[0007] By adopting the above technical solution, through the setting of the anticorrosive coating, the anti-corrosion effect of the fixed seat and the stacking frame can be improved, and the service life of the fixed seat and the stacking frame is prolonged.

[0008] The present utility model is further configured as: the stacking frame is in a downward inclined state after installation.

[0009] By adopting the above technical solution, the nuts placed in the stacking frame can slide naturally under the guidance of gravity.

[0010] The present utility model is further configured as: connecting plates are symmetrically welded to the front surface of the second pushing plate, and the other ends of the connecting plates penetrate and extend to the outside of the fixed seat.

[0011] By adopting the above technical solution, through the setting of the connecting plates, the nuts in the stacking frame can be blocked, avoiding the situation that nuts accidentally enter during the movement of the second pushing plate.

[0012] The present utility model is further configured as: a spring washer is slidably sleeved on the surface of the threaded rod.

[0013] By adopting the above technical solution, through the setting of the spring washer, it can prevent the fixed nut from loosening during and after installation.

[0014] The present utility model is further configured as: both the threaded rod and the fixed nut are made of stainless steel.

[0015] By adopting the above technical solution, the threaded rod and the fixed nut have the characteristics of high strength, low density and excellent corrosion resistance.

[0016] In summary, the present utility model has the following beneficial effects:

[0017] 1. In the present utility model, first place the components on the tapping machine and fit them to the fixture, then fix the U-shaped base with screws. After the U-shaped base is fixed, grasp the fixed seat and pull it upward. When the fixed seat is pulled upward, it will drive the fixing plate and the threaded rod to move upward together. When the fixed seat moves upward to the position of the discharge port and coincides with the height of the fixture, use tools to grasp the fixed nut and tighten it to fix the fixing plate. It can have a height adjustment function, making it coincide with the surface of fixtures with different thicknesses, avoiding obstacles to the nuts after they are pushed out, and having good flexibility;

[0018] 2. When the tapping machine is of the one - in - one type, pick up the partition board and insert the clamping plate on its back into the card slot. After the partition board is inserted, arrange the nuts in the stacking frame in sequence. After the nuts are placed, first start the second cylinder to drive the second pushing plate to move backward. When the second pushing plate moves backward, it will push the single nut that slides down into the fixed seat to move. When the second pushing plate is pushed to the end, start the first cylinder. After the first cylinder is started, it will drive the first pushing plate to push the nut out of the fixed seat. It can adjust the single - push quantity, is simple and labor - saving in operation, is applicable to different types of tapping machines, and has high practicability.
