Description

Technical Field

[0001] The present invention relates to a feeding device for shaft workpieces. Background Art

[0002] Chinese Patent with application number 202122833263.9 discloses a feeding and sorting device for shaft parts, including an aggregate box, an inclined guide groove arranged along the outer edge of the aggregate box, a pushing plate slidably arranged at the bottom of the aggregate box and used to push the shaft parts in the aggregate box upward one by one into the inclined guide groove, a positioning seat arranged below the inclined guide groove; a guiding plate arranged between the inclined guide groove and the positioning seat and used to turn the shaft parts rolled out of the inclined guide groove from a horizontal state to a vertical state; a pressing rod arranged above the positioning seat and used to vertically push the shaft parts into the positioning seat.

[0003] The above solution can make the shaft workpiece slide vertically into the positioning seat with a receiving groove, and can make the shaft workpiece in a vertical state after feeding. However, the above solution has the following defects: the shaft workpiece slides along the inclined guide groove and is turned to a vertical state, and then slides into the receiving groove of the positioning seat. To facilitate the shaft workpiece to slide into the receiving groove, the inner diameter of the receiving groove is much larger than that of the shaft workpiece. Therefore, the shaft workpiece may shake on the positioning seat, it is difficult to determine the coaxiality of the shaft workpiece, and it is not convenient to pick up the shaft workpiece by a clamping jaw for subsequent processing or assembly. Summary of the Invention

[0004] The purpose of the present invention is to provide a feeding device for shaft workpieces that can better ensure the coaxiality of the shaft workpieces, so as to facilitate subsequent transfer.

[0005] To achieve the above purpose, the present invention adopts the following technical scheme: a feeding device for shaft workpieces, including a discharge block, the discharge block has a through groove penetrating up and down, the upper end of the through groove is connected to a feeding mechanism for realizing the conveying of shaft workpieces, the side of the discharge block is open to form a first fitting groove communicating with the through groove, a partition member is arranged at the first fitting groove, the partition member has a through hole penetrating up and down, the partition member is equipped with a first driving mechanism for translating the partition member and making the through hole communicate with the through groove, an elastic clamping block is arranged below the discharge block, the elastic clamping block has a clamping hole with an upward opening and located directly below the through groove, and the elastic clamping block is equipped with a second driving mechanism for realizing the lifting of the elastic clamping block.

[0006] When the shaft workpiece passes through the through groove and lands on the elastic clamping block, at this time, the lower end of the shaft workpiece is pre-placed at the clamping hole, the upper end of the shaft workpiece is located within the lower section of the through groove, and the first driving mechanism controls the partition member to extend into the through groove to seal the through groove. Subsequently, the elastic clamping block rises under the action of the second driving mechanism, so that the elastic clamping block pushes the shaft workpiece upward until the upper end of the shaft workpiece contacts the lower end face of the partition member. As the elastic clamping block continues to move upward, the lower end of the shaft workpiece will enter the clamping hole, and the shaft workpiece will be tightly fitted in the clamping hole. Finally, the second driving mechanism drives the elastic clamping block to move downward so that the upper end of the shaft workpiece moves out of the through groove.

[0007] In the present invention, the elastic clamping block made of rubber or other materials with certain elastic deformation is used to clamp the shaft workpiece to prevent the shaft workpiece from shaking after loading. The lower section of the through groove is used to guide the shaft workpiece, thereby ensuring the coaxiality of the shaft workpiece, and further realizing the precise loading of the shaft workpiece, so as to facilitate the subsequent picking up of the shaft workpiece by the clamping jaw. Among them, when the shaft workpiece falls from the through groove, since part of the shaft workpiece is located outside the through groove, the shaft workpiece may be inclined to a certain extent, and there may be a certain offset in the lower section of the shaft workpiece. The elastic clamping block of the present invention has certain elasticity. When the shaft workpiece is pressed and moves downward, the elastic clamping block will adaptively undergo elastic deformation. As long as the lower end of the shaft workpiece does not completely break away from the clamping hole, with the axial force on the shaft workpiece, the lower end of the shaft workpiece will be stuck in the clamping hole.

[0008] Preferably, the side of the discharge block is provided with an opening to form a second mating groove communicating with the through groove. The second mating groove is located above the first mating groove, and a pressing member is provided at the second mating groove. When the end of the pressing member extends into the through groove, the through hole of the partition member communicates with the through groove. When the end of the pressing member disengages from the through groove, the through groove is blocked by the partition member.

[0009] The present invention is provided with a pressing member to realize the individual output of the shaft workpieces. When the through hole communicates with the through groove, the pressing member presses the second shaft workpiece from the bottom up. When the through hole deviates from the through groove, the through groove is blocked by the partition member, and the pressing member moves outward to release the shaft workpiece so that the shaft workpiece can fall on the partition member.

[0010] Preferably, both the pressing member and the partition member are fixed to the linkage block, and the linkage block is fixed to the output end of the first driving mechanism. The pressing member and the partition member of the present invention are simultaneously linked, which can save a driving mechanism and make the operation of the present invention smoother.

[0011] Preferably, the elastic clamping block is composed of two relatively arranged clamping block monomers, and the two clamping block monomers are joined together so that a clamping hole is formed between the two clamping block monomers. The elastic clamping block composed of two joined clamping block monomers is more convenient for the shaft workpiece to be pressed into the clamping hole.

[0012] Preferably, a first conical surface guiding groove is connected to the upper end of the clamping hole, and the inner diameter of the first conical surface guiding groove gradually decreases from top to bottom, so that the groove surface of the first conical surface guiding groove is smoothly connected to the inner wall of the clamping hole. The first conical surface guiding groove is provided to facilitate the inclined shaft workpiece to enter the clamping hole along the conical surface of the first conical surface guiding groove, so as to realize the self-adaptive centering adjustment.

[0013] Preferably, a support plate is provided on the lower side of the elastic clamping block, and the support plate is provided with a mating hole that opens upward and is coaxial with the clamping hole. When the shaft workpiece passes through the clamping hole and extends into the mating hole, the more structurally strong support plate is used to limit the movement of the shaft workpiece, so as to ensure the coaxiality of the lower end of the shaft workpiece and avoid the shaft workpiece from tilting.

[0014] Preferably, a second conical surface guiding groove is connected to the upper end of the mating hole, and the inner diameter of the second conical surface guiding groove gradually decreases from top to bottom, so that the groove surface of the second conical surface guiding groove is smoothly connected to the inner wall of the mating hole. The conical surface of the second conical surface guiding groove facilitates the adjustment of the position of the shaft workpiece under the action of the vertical pressure, and at the same time, the second conical surface guiding groove can also play a certain role of making way, enabling the shaft workpiece to extend deeper into the mating hole, but reducing the contact area between the shaft workpiece and the inner wall of the mating hole, so as to facilitate the shaft workpiece to be pressed into the mating hole.

[0015] Preferably, a relief groove is connected to the lower end of the clamping hole, the inner diameter of the relief groove gradually increases from top to bottom, and the inner diameter of the lower end of the relief groove is larger than the inner diameter of the mating hole. The relief groove can make the shaft workpiece extend deeper into the clamping hole, so that the coaxiality of the shaft workpiece is better, but reduce the contact area between the shaft workpiece and the inner wall of the clamping hole, so as to facilitate the shaft workpiece to be pressed into the clamping hole.

[0016] Preferably, a lifting plate is provided at the output end of the second driving mechanism, and a third driving mechanism is provided on the lifting plate. Under the action of the third driving mechanism, the elastic clamping block translates and moves out from directly below the discharging block. By providing the third driving mechanism, the translation of the elastic clamping block can be realized, so as to move the vertically arranged shaft workpiece away, so as to facilitate the subsequent clamping transfer and pressing of the shaft workpiece.

[0017] The present invention has the advantages of being able to ensure the accuracy of the position of the shaft workpiece after loading, improving the coaxiality of the shaft workpiece, and facilitating the subsequent taking away of the shaft workpiece by the clamping jaw.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] As Figure 1 shown, this embodiment discloses a feeding device for shaft workpieces, including a discharge block 1. The discharge block 1 has a through groove 11 that penetrates up and down. The upper end of the through groove 11 is connected to a feeding mechanism 2 for realizing the conveyance of shaft workpieces 100. The feeding mechanism 2 in this embodiment is a vibrating disk, and a guiding hose 21 is connected between the upper end of the through groove 11 and the output end of the vibrating disk.

[0023] As Figure 1 and Figure 2 shown, the side of the discharge block 1 is open to form a first mating groove and a second mating groove that communicate with the through groove 11. The second mating groove is located above the first mating groove. A partition member 3 is provided at the first mating groove. The partition member 3 has a through hole 31 that penetrates up and down. The partition member 3 is equipped with a first driving mechanism 32 for translating the partition member and making the through hole 31 communicate with the through groove 11. A pressing member 4 is provided at the second mating groove. Both the pressing member 4 and the partition member 3 are fixed to a linkage block 33, and the linkage block 33 is fixed to the output end of the first driving mechanism 32. The first driving mechanism in this embodiment is a cylinder. When the end of the pressing member 4 extends into the through groove 11, the through hole 31 of the partition member 3 communicates with the through groove 11. When the end of the pressing member 4 disengages from the through groove 11, the through groove is blocked by the partition member 3.

[0024] Among them, an observation port is also provided at the side opening of the discharge block 1, and a detection sensor 12 is provided at the observation port. The detection sensor 12 is used to detect whether there is a shaft workpiece 100 on the side of the detection sensor. The length of the shaft workpiece in this embodiment is greater than the distance between the upper end surface of the partition member 3 and the lower edge of the detection end of the detection sensor.

[0025] As Figure 1 and Figure 3 shown, an elastic clamping block 5 is provided below the discharge block 1. The elastic clamping block 5 has a clamping hole 51 that opens upward and is located directly below the through groove 11. The elastic clamping block 5 is equipped with a second driving mechanism 50 for realizing the lifting of the elastic clamping block 5.

[0026] The elastic clamping block 5 is composed of two clamping block monomers 54 arranged opposite to each other, and a semi-arc groove is provided on the side of each clamping block monomer. The two clamping block monomers are assembled so that the two semi-arc grooves between the two clamping block monomers constitute the clamping hole 51. A support plate 6 is provided on the lower side of the elastic clamping block 5, and the support plate 6 is provided with a matching hole 61 which is open upward and coaxial with the clamping hole 51. A lifting plate 501 is provided at the output end of the second driving mechanism 50, and a third driving mechanism 60 is provided on the lifting plate 501. Under the action of the third driving mechanism 60, the elastic clamping block 5 is translated and moved out from directly below the discharge block 1. The second driving mechanism of this embodiment is a lifting cylinder, and the third driving mechanism is a translation cylinder.

[0027] Depend on Figure 3 As shown, the upper end of the clamping hole 51 is connected to a first conical guide groove 511, and the inner diameter of the first conical guide groove 511 gradually decreases from top to bottom, so that the groove surface of the first conical guide groove 511 is smoothly connected to the inner wall of the clamping hole 51. The lower end of the clamping hole 51 is connected to a clearance groove 512, and the inner diameter of the clearance groove 512 gradually increases from top to bottom, and the inner diameter of the lower end of the clearance groove 512 is larger than the inner diameter of the matching hole 61. The upper end of the matching hole 61 is connected to a second conical guide groove 611, and the inner diameter of the second conical guide groove 611 gradually decreases from top to bottom, so that the groove surface of the second conical guide groove 611 is smoothly connected to the inner wall of the matching hole 61.

[0028] When the shaft workpiece on the vibration plate passes through the guide hose, it will enter the through groove, and then the shaft workpiece will be supported on the partition piece. After the detection sensor detects the shaft workpiece, the first driving mechanism is started, the partition piece moves and connects the through hole with the through groove, and the clamping piece moves toward the through groove. After a shaft workpiece passes through the through hole, the partition piece will block the through groove, and a new shaft workpiece will be pressed against the wall of the through groove by the clamping piece.

[0029] At this time, the shaft workpiece at the bottom is supported on the elastic clamping block, the lower end of the shaft workpiece at the bottom is pre-placed in the clamping hole, and the upper end of the shaft workpiece is located in the lower section of the through slot. Then the second drive mechanism is started to raise the elastic clamping block, so that the elastic clamping block pushes the shaft workpiece to move upward until the upper end of the shaft workpiece contacts the lower end surface of the partition, and as the elastic clamping block continues to move upward, the lower end of the shaft workpiece at the bottom will pass through the clamping hole and enter the matching hole and match the gap with the matching hole, and the shaft workpiece will fit tightly in the clamping hole near the lower end, and the shaft workpiece will fit tightly in the clamping hole, and the second drive mechanism drives the elastic clamping block to move downward to move the upper end of the shaft workpiece out of the through slot, and finally the third drive mechanism drives the support plate to translate, so that the shaft workpiece moves to the side of the discharge block, so that the clamping claw can take the shaft workpiece away.
