Description

Technical Field

[0001] The utility model relates to nut processing, in particular to a placement structure for temporary sampling inspection after nut tapping. Background Art

[0002] After the nuts are tapped and the corresponding entire processing steps are completed, they are collected. After completing the processing steps, the nuts need to be inspected to ensure quality. Because the nuts are small in size and there are a lot of them, the workload of inspecting them one by one is too large, so the current inspection method generally adopts random inspection. Specifically, the nuts are divided into multiple small batches, and a certain number of nuts are sampled from each small batch for inspection. If the qualified rate of the inspected nuts meets the requirements, the nuts in this small batch are considered qualified, otherwise they are unqualified. The current inspection is to divide the nuts into multiple small batches for inspection after they are collected, which makes the operation process cumbersome, the process is not simplified enough, and it is time-consuming and labor-intensive.

[0026] See also Figure 1 A placement structure for temporary sampling of nuts after tapping, comprising a base 1, a placement box 2, a plurality of baffles 3 and a discharging mechanism 4.

[0027] The top of the base 1 is open, thereby forming a first cavity 1a.

[0028] The top of the placement box 2 is open, serving as an inlet, that is, the nuts tapped on the nut tapping machine enter the placement box 2 from the inlet. The vertical side of one side of the placement box 2 is also open, serving as an outlet, that is, the nuts in the subsequent placement box 2 can leave the placement box 2 from the outlet.

[0029] The placement box 2 is arranged above the base 1, and the bottom plate 2a is provided with filter holes (for convenience of representation, the filter holes on the bottom plate 2a are shown in the attached figure). Because the tapping step has just been completed, the nuts entering the placement box 2 generally still have some coolant attached to them, and through the filter holes, the coolant on the nuts can fall and flow into the first cavity 1a of the base 1. Accordingly, when a certain amount of coolant is collected in the first cavity 1a, it can be pumped out by a pump for reuse; or the first cavity 1a can be provided with a pipe interface, which is connected to the coolant tank through a pipe, so that the coolant in the first cavity 1a can flow back to the coolant tank for reuse.

[0030] A plurality of partitions 2b are also provided in the placement box 2, and the plurality of partitions 2b divide the placement box 2 into a plurality of second cavities 2c. Accordingly, each second cavity 2c naturally also has an inlet and an outlet.

[0031] The plurality of baffles 3 are movably connected to the positions of the outlets of the plurality of second cavities 2c in sequence, and the outlets of the second cavities 2c can be switched between closed and open states through the movement of the baffles 3 relative to the second cavities 2c. Specifically, the baffles 3 can be inserted at the position of the outlets of the second cavities 2c, and when the baffles 3 are inserted, the outlets of the second cavities 2c are in a closed state; when the baffles 3 are pulled out, the outlets of the second cavities 2c are in an open state.

[0032] The discharging mechanism 4 acts on the placing box 2 to discharge the second cavity 2c with the outlet in the placing box 2 opened, that is, the nuts in the second cavity 2c can leave from the outlet.

[0033] Briefly describe how this application works:

[0034] S1, all outlets of the second cavity 2c are closed, and the tapped nuts are collected;

[0035] S2. After the first number of nuts in the second cavity 2c is collected, the collection is stopped. Each second cavity 2c contains a batch of nuts for sampling inspection:

[0036] S3, sequentially extracting a certain number of nuts from each second cavity 2c for random inspection, and for nuts that pass the random inspection, switching the outlet of the corresponding second cavity 2c to an open state;

[0037] S4, the discharging mechanism 4 works, so that the nuts that pass the random inspection leave from the outlet of the second cavity 2c, and a material frame can be placed below to receive the nuts;

[0038] S5. After the nuts that have passed the random inspection are discharged, the material frame is replaced and the nuts that have failed the random inspection are also discharged.

[0039] See also Figure 2 , Optionally, the first configuration of the discharging mechanism 4 may be: the discharging mechanism 4 includes a plurality of push plates 4a and a plurality of first cylinders 4b. Correspondingly, the configuration of the placing box 2 and the base 1 may be: the placing box 2 is directly fixedly connected to the base 1. That is, a push plate 4a and a first cylinder 4b are a group, which are arranged in a second cavity 2c. Specifically, the first cylinder 4b is fixedly connected to the vertical side surface of the placing box 2 opposite to the outlet; the push plate 4a is in the second cavity 2c and is fixedly connected to the piston rod of the first cylinder 4b.

[0040] In this way, the push plate 4a is pushed to move by the first cylinder 4b, and the nuts in the second cavity 2c are pushed out from the outlet. The nut discharge speed is relatively fast, but the cylinder body of the first cylinder 4b is relatively long and needs to occupy a considerable space outside the box body 2.

[0041] See also Figure 3, Optionally, the second setting of the discharging mechanism 4 can be: the discharging mechanism 4 is a vibration motor 4c, and the vibration motor 4c is fixedly connected to the bottom plate 2a of the placement box 2. Correspondingly, the placement box 2 and the base 1 can be set as follows: the placement box 2 and the base 1 can move relative to each other in the up and down directions and are provided with a first compression spring 2e. Specifically, the base 1 has a plurality of connecting ears 1b on two opposite vertical side surfaces, and the placement box 2 is threadedly connected to the position corresponding to the connecting ear 1b with a bolt 2d passing through the connecting ear 1b, and the first compression spring 2e is sleeved on the bolt 2d, and the two ends respectively resist the placement box 2 and the connecting ear 1b.

[0042] In this way, the vibrating motor 4c is used to shake the placing box 2 up and down, so that the nuts in the second cavity 2c can leave from the outlet. The speed at which the nuts leave from the outlet is relatively slow, but when the outlets of the second cavity 2c are all closed and still collecting nuts, the vibrating motor 4c can also be operated to make the coolant on the nuts fall more conveniently and flow into the first cavity 1a of the base 1.

[0043] See also Figure 4 Optionally, the third configuration of the discharging mechanism 4 may be: the discharging mechanism 4 is a second cylinder 4d. Accordingly, the configuration of the placing box 2 and the base 1 may be: a side corresponding to the outlet of the placing box 2 is hinged to the base 1, and specifically, a hinge connection member may be used between the two. The second cylinder 4d is disposed between the base 1 and the placing box 2, so that the placing box 2 can be switched between a horizontal state and a tilted state with the outlet facing downward.

[0044] In this way, when the box body 2 is placed in a tilted state, the nut in the second cavity 2c can fall out from the outlet.

[0045] See also Figure 5 Optionally, the bottom plate 2a of the placement box 2 is hinged to the placement box 2. Specifically, a hinge connection can be used between the two. The placement box 2 is provided with a switch acting on the bottom plate 2a on the side away from the hinge position, so that the bottom plate 2a can be switched between the closed and open states. Specifically, the switch can be multiple groups, each group includes a blocking rod 2f and a second compression spring 2g. Under the action of the second compression spring 2g, the blocking rod 2f penetrates under the bottom plate 2a to block the bottom plate 2a, so that the bottom plate 2a remains in a closed state; overcome the second compression spring 2g, pull out the blocking rod 2f, and the bottom plate 2a is switched to an open state.

[0046] In this way, compared with the bottom plate 2a being integrally arranged on the placement box 2, in the above-mentioned step S5, it is only necessary to directly open the bottom plate 2a, so that the nuts that fail the random inspection fall into the first cavity 1a of the base 1 along the bottom plate 2a. A removable mesh plate can also be placed on the first cavity 1a to receive these nuts without affecting the coolant falling into the first cavity 1a of the base 1.
