Technical Field

[0001] The utility model relates to the technical field of relay manufacturing, and particularly relates to a skeleton pin inserting device for relay manufacturing. Background Technique

[0002] In the operation of a relay, the skeleton plays a very important role. In the use of the skeleton, several metal through pins usually need to be inserted into the skeleton to make the skeleton function. However, the speed of manual pin insertion is very slow.

[0003] According to the patent with the patent application number 202022329878.3 and the patent name of a skeleton pin inserting device for relay manufacturing, this patent includes a bottom plate. The middle part of the upper end of the bottom plate is fixedly connected with a support frame. A limiting groove is opened at the right end of the support frame.

A transmission device is slidably connected in the guide rail, and the right part of the transmission device is fixedly connected to the upper end of the bottom plate. The rear part of the upper end of the bottom plate is fixedly connected with a feeding plate. An inlet groove is opened in the middle of the upper end of the feeding plate. A plurality of through pins are slidably connected in the inlet groove. For the skeleton pin inserting device for relay manufacturing described in this utility model, by setting the pin inserting device, through the movement of the vibration cylinder, the needle taking and pin inserting can be quickly reciprocated, so as to quickly carry out the pin inserting work and save the working time.

[0004] Although the above patent can quickly reciprocate the needle taking and pin inserting, so as to quickly carry out the pin inserting work and save the working time, because its needle taking and pin inserting are two independent operation steps, the pin inserting operation can only be carried out after the needle taking, and the needle taking operation cannot be carried out during the pin inserting process, so to a certain extent, the pin inserting efficiency cannot be maximally improved. Therefore, in view of the above problems, a skeleton pin inserting device for relay manufacturing is proposed. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A skeleton pin inserting device for relay manufacturing, comprising a bracket. At the inner bottom end of the bracket, a multi-stage electric push rod is fixedly connected. At the left end of the multi-stage electric push rod, a sliding seat slidably connected to the bracket is fixedly connected. Inside the sliding seat, a skeleton is slidably connected to the top end. At the right end of the bracket, a controller is fixedly connected. At the inner top end of the bracket, an electric push rod is fixedly connected. At the bottom end of the electric push rod, a push plate is fixedly connected. At the bottom end of the push plate, an inserting shaft is fixedly connected. At the left side of the top end of the bracket, a feeding plate is fixedly connected through a connecting rod. On the top end of the feeding plate, steel pins are provided, and the leftmost steel pin is slidably connected to the feeding plate.

[0008] As a further improvement of the present utility model, a tightening bolt is spirally connected to the right end of the sliding seat, and the tightening bolt penetrates through the sliding seat and is in close contact with the skeleton.

[0009] As a further improvement of the present utility model, a magnet is provided at the inner bottom end of the inserting shaft, and the magnet is fixedly connected to the inserting shaft.

[0010] As a further improvement of the present utility model, a rubber sleeve is fixedly connected to the inner right end of the feeding plate, and the rubber sleeve is in contact with the rightmost steel pin.

[0011] As a further improvement of the present utility model, a fixing block is fixedly connected to the outer side of the feeding plate. Inside the fixing block, a feeding rod penetrating through the fixing block is slidably connected. At the outer top end of the feeding rod, a fixing rod is fixedly connected. At the outer bottom end of the feeding rod, a sliding plate and a spring are arranged vertically. The sliding plate is fixedly connected to the feeding rod, the sliding plate is slidably connected to the fixing block, and the spring is fixedly connected to the sliding plate and the fixing block.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. For a skeleton pin inserting device for relay manufacturing, through the arranged electric push rod, multi-stage electric push rod, sliding seat, skeleton, feeding plate, inserting shaft, steel pins and magnet, when performing the pin inserting operation on the relay skeleton through the device, control the multi-stage electric push rod to extend three times with a fixed length, ensuring that the three pairs of jacks at the top of the skeleton just move to the bottom of the two rightmost steel pins each time. Then, each time the multi-stage electric push rod completes an extension with a fixed length, control the electric push rod to perform a telescopic movement, thereby controlling the push plate to drive the inserting shaft to move down and sleeve on the outer side of the rightmost steel pin, making the magnet attract the rightmost steel pin. Then, when continuously pushing down the rightmost steel pin, the rightmost steel pin continuously passes through the rubber sleeve and further inserts into the jack at the top of the skeleton. By removing the rightmost steel pin and inserting it into the skeleton during the process of controlling the electric push rod to extend and drive the push plate to drive the inserting shaft to move down for the pin inserting operation, the operation of taking the pin is realized during the pin inserting process, thereby maximizing the pin inserting efficiency.

[0014] 2. A pin inserting device for the skeleton used in the production of a relay. By means of the arranged fixed rod, feeding rod, slide plate and spring, during the process that the insertion shaft at the bottom of the push plate is driven by the extended electric push rod to drive the rightmost steel needle to insert into the skeleton, since the push plate will also push the fixed rod before moving to the bottom, further controlling the feeding rod to slide down to drive the slide plate to compress the spring once. Therefore, when the electric push rod resets after a pin inserting operation is completed, the fixed rod is pushed by the push plate and then reset, and the fixed rod drives the feeding rod to perform an up-and-down reciprocating motion under the elastic force of the spring on the slide plate, realizing automatically putting down a pair of steel needles to slide to the right side of the feeding plate to prepare for the next pin inserting operation after a pin inserting operation is completed, thereby making the pin inserting operation of the relay skeleton more convenient.

[0022] Embodiment 1

[0023] As Figures 1-4 shown, a pin inserting device for the skeleton used in the production of a relay includes a bracket 1. A multi-stage electric push rod 2 is fixedly connected to the inner bottom end of the bracket 1. A sliding seat 3 slidably connected to the bracket 1 is fixedly connected to the left end of the multi-stage electric push rod 2. A skeleton 4 is slidably connected to the inner top end of the sliding seat 3. A controller 6 is fixedly connected to the right end of the bracket 1. An electric push rod 7 is fixedly connected to the inner top end of the bracket 1. A push plate 8 is fixedly connected to the bottom end of the electric push rod 7. A plug shaft 9 is fixedly connected to the bottom end of the push plate 8. A feeding plate 11 is fixedly connected to the left side of the top end of the bracket 1 through a connecting rod. Steel needles 12 are arranged on the top end of the feeding plate 11, and the leftmost steel needle 12 is slidably connected to the feeding plate 11.

[0024] Embodiment 2

[0025] As Figures 1-2 shown, in order to solve the problem that when controlling the electric push rod 7 to contract and reset after one pin insertion, the skeleton 4 cannot be prevented from being taken out of the sliding seat 3, a tightening bolt 5 is screwed to the right end of the sliding seat 3, and the tightening bolt 5 penetrates through the sliding seat 3. The tightening bolt 5 is in close contact with the skeleton 4. By rotating the tightening bolt 5 to be in close contact with the skeleton 4 in the sliding seat 3, the skeleton 4 can be positioned in the sliding seat 3, so that when controlling the electric push rod 7 to contract and reset after one pin insertion, the skeleton 4 can be prevented from being taken out of the sliding seat 3.

[0026] Embodiment 3

[0027] As Figure 2As shown in the figure, to solve the problem that the rightmost steel needle 12 cannot be stably pushed into the jack at the top of the skeleton 4 by the insertion shaft 9, a magnet 10 is provided at the inner bottom end of the insertion shaft 9, and the magnet 10 is fixedly connected to the insertion shaft 9. When controlling the insertion shaft 9 to push the steel needle 12 into the jack at the top of the skeleton 4, by first sleeving the insertion shaft 9 outside the rightmost steel needle 12, and then making the magnet 10 at the inner bottom of the insertion shaft 9 attract the rightmost steel needle 12, when controlling the electric push rod 7 to extend, the rightmost steel needle 12 is stably pushed into the jack at the top of the skeleton 4 by the insertion shaft 9.

[0028] Embodiment 4

[0029] As Figure 1 、 Figure 2 and Figure 4 shown in the figure, to solve the problem that it is not convenient to push the rightmost steel needle 12 off the feeding plate 11, a rubber sleeve 13 is fixedly connected to the inner right end of the feeding plate 11, and the rubber sleeve 13 is in contact with the rightmost steel needle 12. By arranging the rubber sleeve 13 at the inner right end of the feeding plate 11, when controlling the insertion shaft 9 to push the rightmost steel needle 12, the rubber sleeve 13 deforms, which facilitates pushing the rightmost steel needle 12 off the feeding plate 11.

[0030] Embodiment 5

[0031] As Figures 1-3 shown in the figure, to solve the problem that it is not convenient to automatically perform a feeding operation after one needle insertion, a fixing block 14 is fixedly connected to the outside of the feeding plate 11. A feeding rod 15 penetrating the fixing block 14 is slidably connected to the inside of the fixing block 14. A fixing rod 16 is fixedly connected to the outer top end of the feeding rod 15. A slide plate 17 and a spring 18 are arranged up and down on the outer bottom end of the feeding rod 15, and the slide plate 17 is fixedly connected to the feeding rod 15. The slide plate 17 is slidably connected to the fixing block 14, and the spring 18 is fixedly connected to the slide plate 17 and the fixing block 14. After the electric push rod 7 completes one expansion and contraction, and thus completes one needle insertion operation, before performing the needle insertion operation, the electric push rod 7 is used to push the fixing rod 16 through the push plate 8, further making the feeding rod 15 drive the slide plate 17 to compress the spring 18 and move downward, so that a pair of steel needles 12 slide to the right side of the feeding plate 11 without being blocked by the bottom of the feeding rod 15. When the electric push rod 7 resets, the feeding rod 15 resets under the elastic force of the spring 18 on the slide plate 17, and further the bottom of the feeding rod 15 blocks the remaining steel needles 12 again, which facilitates automatically performing a feeding operation after one needle insertion.

[0032] In this embodiment, when performing the pin insertion operation on the relay skeleton 4 through the device, the skeleton 4 is placed into the sliding seat 3, and then the tightening bolt 5 is rotated to be screwed with the sliding seat 3 to further tighten and position the skeleton 4. After the above operations are completed, the device is started through the controller 6. At this time, under the control of the controller 6, the multi-stage electric push rod 2 will extend three times with a fixed length. And each time the multi-stage electric push rod 2 extends, a pair of the three pairs of jacks at the top of the skeleton 4 just moves to the bottom of the two steel needles 12 on the far right, and the controller 6 will control the electric push rod 7 to perform a telescopic motion once, so as to control the push plate 8 to drive the insertion shaft 9 to move downward and sleeve on the outside of the steel needle 12 on the far right, so that the magnet 10 is attracted to the steel needle 12 on the far right. Then when continuously pushing down the steel needle 12 on the far right, the steel needle 12 on the far right continuously penetrates through the rubber sleeve 13 to cause the rubber sleeve 13 to deform, and then inserts into a pair of jacks at the top of the skeleton 4, so as to realize one pin insertion operation. When the electric push rod 7 contracts and resets after completing the pin insertion operation on a pair of jacks at the top of the skeleton 4, because the friction between the steel needle 12 and the skeleton 4 is relatively large after the steel needle 12 is inserted into the skeleton 4, and the skeleton 4 is positioned in the sliding seat 3 through the tightening bolt 5, so when the electric push rod 7 contracts and resets, the steel needle 12 will automatically separate from the magnet 10 at the inner bottom end of the insertion shaft 9. During the process that the insertion shaft 9 at the bottom of the push plate 8 drives the steel needle 12 on the far right to insert into the skeleton 4 when the electric push rod 7 extends, because the push plate 8 will also push the fixed rod 16 before moving to the bottom, further controlling the feeding rod 15 to slide downward to drive the sliding plate 17 to compress the spring 18 once, so when the electric push rod 7 resets after completing one pin insertion operation, the push plate 8 first pushes the fixed rod 16 downward and then resets upward, so that the fixed rod 16 drives the feeding rod 15 to perform a reciprocating motion of moving downward and then upward under the elastic force of the spring 18 on the sliding plate 17. When the feeding rod 15 slides downward, the bottom of the feeding rod 15 will no longer block the first pair of steel needles 12 in contact at the bottom, and the top of the feeding rod 15 will block the second pair of steel needles 12 in contact at the top. Then the first pair of steel needles 12 will slide to the right side of the feeding plate 11 to prepare for the next pin insertion. When the feeding rod 15 slides upward and resets, the bottom of the feeding rod 15 will block the steel needle 12 on the left again, and the top of the feeding rod 15 will no longer be in contact with the steel needle 12, so as to realize automatically feeding once after completing one pin insertion operation to prepare for the next pin insertion, making the pin insertion operation of the relay skeleton 4 more convenient. When the multi-stage electric push rod 2 completes three telescopic motions and the three pairs of jacks at the top of the skeleton 4 have all completed the pin insertion operation, reset the multi-stage electric push rod 2, and then reverse the tightening bolt 5 to remove the skeleton 4 after pin insertion.
