Description

Technical Field

[0001] The invention relates to the technical field of commutators, in particular to a commutator single-head shelling device. Background Art

[0002] The commutator requires that two adjacent commutator segments must be insulated to prevent the two adjacent commutator segments from being electrically conductive to each other and causing the commutator to malfunction. After the commutator is initially processed and before insulation treatment is performed, an insulating plastic shell is usually placed on the commutator, and the copper commutator segments are inserted into the plastic shell to maintain insulation. In the next step of adding a carbon coating to the commutator segments, the plastic shell on the commutator needs to be removed.

[0003] At present, the commonly used method for removing the plastic shell in the prior art is generally to use a lathe to cut an annular cutting groove 011 on the side wall of the commutator with the plastic shell, such as Figure 1 As shown, the plastic shell is divided into two parts that are easy to remove from the commutator, namely the main material 012 and the residual material 013, and a weak connection part is left between the main material 012 and the residual material 013; and the two parts of the plastic shell are mostly separated from the commutator by manual operation.

[0004] The above manual operation mode has low working efficiency, high labor intensity for the staff, and is not conducive to the mass production of products. Summary of the invention

[0005] The purpose of the present invention is to provide a commutator single-head shelling device, which can realize automatic shelling, reduce the workload of people and improve production efficiency.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A commutator single-head shelling device comprises a mounting frame, on which a conveying mechanism, a clamping and pushing mechanism, a cutting mechanism, a main material removing mechanism and a residual material removing mechanism are arranged; the conveying mechanism conveys the workpiece to the clamping and pushing mechanism; the clamping and pushing mechanism fixes the workpiece and conveys it stably to the cutting mechanism, and the cutting mechanism surrounds a plastic shell sleeved on the side wall of the workpiece to form a cutting groove; the conveying mechanism conveys the processed workpiece to the main material removing mechanism, and the main material removing mechanism separates the main material from the residual material and separates the main material from the workpiece; the conveying mechanism conveys the workpiece after the main material is separated to the residual material removing mechanism, and the residual material removing mechanism removes the residual material on the workpiece and conveys it to the next process through the conveying mechanism.

[0008] By adopting the above technical solution, the device connects the clamping and pushing mechanism, the cutting mechanism, the main material removing mechanism, and the waste material removing mechanism in series through the conveying mechanism, and each mechanism can operate independently, effectively improving the automation level of the device.

[0009] The present invention is further configured as follows: The clamping and pushing mechanism includes a first clamping device. The first clamping device includes a first pushing cylinder disposed on the mounting rack, and a first fixing seat is provided at the end of the piston rod of the first pushing cylinder; a first clamping groove for placing the workpiece is provided at one end of the first fixing seat away from the first pushing cylinder. When the workpiece is located in the first clamping groove, the side wall of the workpiece abuts against the inner wall of the first clamping groove; a jacking cylinder is provided on the front side of the fixing seat, and a jacking rod opposite to the position of the first clamping groove is provided at the end of the piston rod of the jacking cylinder; the first pushing cylinder can transfer the workpiece on the first clamping groove to the front side of the cutting mechanism, and drive the jacking rod through the jacking cylinder to transport the workpiece on the first clamping groove to the cutting mechanism.

[0010] By adopting the above technical solution, the workpiece enters the first clamping groove through the conveying mechanism. The workpiece is stuck in the first clamping groove and difficult to move, ensuring the accuracy of feeding. The pushing cylinder sends the workpiece to the front side of the cutting mechanism. The jacking cylinder works to eject the workpiece from the clamping groove and push it onto the cutting mechanism for the next process. The process of workpiece feeding is driven by a cylinder, without additional manual operation, improving the automation level and production efficiency.

[0012] By adopting the above technical solution, the workpiece transported by the jacking cylinder is fixed by the fixing device, and the cutting device processes the workpiece to facilitate the subsequent removal of the plastic shell. After the workpiece is processed, the top material device ejects the workpiece from the working position and waits for the conveying mechanism to transport the workpiece to the next process for processing; while the driving motor drives the rotating shaft to rotate, the elastic chuck clamps the workpiece, without manual operation, and the whole process is more efficient and convenient.

[0013] The present invention is further configured such that: the cutting device includes a cutting cylinder disposed on the clamping seat, a cutting tool with a tool tip facing the axis of the workpiece is provided at the end of the piston rod of the cutting cylinder, and the cutting cylinder can control the cutting tool to circumferentially cut out an annular cutting groove on the side wall of the workpiece along the circumference of the workpiece under the action of the rotation of the rotating shaft on the surface of the plastic shell.

[0014] By adopting the above technical solution, the plastic shell is circumferentially cut by the cutting device, and the plastic shell is divided into a main material and a surplus material, so as to facilitate the subsequent process of removing the plastic shell from the workpiece.

[0015] The present invention is further configured such that: the ejecting device includes an ejecting cylinder disposed on the clamping seat, an ejecting rod coaxial with the rotating shaft is provided on the piston rod of the ejecting cylinder, the end of the ejecting rod passes through the rotating shaft and is in plug-in fit with the rotating shaft, and the ejecting cylinder can drive the ejecting rod to axially eject the workpiece on the elastic chuck away from the clamping seat.

[0016] By adopting the above technical solution, automatic ejecting is realized, space is reasonably utilized, and at the same time automation is achieved, saving time and effort.

[0017] The present invention is further configured such that: the main material removing mechanism includes a placing seat disposed on the mounting frame for placing the workpiece, a tightening and loosening assembly for separating the main material from the surplus material, and an ejecting and pushing device for fixing the workpiece and separating the main material from the workpiece; a fixing ring with an inner wall capable of being in plug-in fit with the workpiece is provided on the front side of the placing seat; the ejecting and pushing device includes a material moving cylinder and a pushing cylinder, the piston rod on the material moving cylinder is coaxial with the fixing ring, and the material moving cylinder can control the piston rod to press the workpiece against the inside of the fixing ring.

[0018] By adopting the above technical solution, the fixing ring and the material moving cylinder cooperate to fix the workpiece, and wait for the subsequent tightening and loosening assembly and the pushing cylinder to separate the main material on the workpiece from the workpiece, realizing automation and reducing human participation.

[0019] The present invention is further configured such that: the tightening and loosening assembly includes a main cylinder, a sub-cylinder, a main clamping member, and a sub-clamping member located between the fixing ring and the material moving cylinder. The main clamping member and the sub-clamping member are horizontally opposite in position, and half grooves horizontally opposite in position are respectively formed at the opposite ends. The piston rod of the material moving cylinder passes through the half grooves; the piston rod of the pushing cylinder is connected to the material moving cylinder and is coaxial with the piston rod of the material moving cylinder; a connecting rod is provided between the pushing cylinder and the tightening and loosening assembly, and the pushing cylinder can drive the tightening and loosening assembly to move axially towards the fixing ring along the fixing ring through the connecting rod; the main cylinder and the sub-cylinder can respectively control the main clamping member and the sub-clamping member to abut against each other and form a circular hole with the two half grooves, and the circular hole is coaxial with the fixing ring; the pushing cylinder can drive the main clamping member and the sub-clamping member to move towards the fixing ring direction and make the inner wall of the circular hole located in the cutting groove.

[0020] By adopting the above technical solution, the movement of the driving cylinder base is utilized to drive the main clamping member and the auxiliary clamping member to approach the fixed ring and move to the outside of the cutting groove of the workpiece. The main cylinder and the auxiliary cylinder control the main clamping member and the auxiliary clamping member to gradually approach and abut, so that the whole formed by the main clamping member and the auxiliary clamping member is sleeved on the workpiece in the cutting groove. The driving cylinder drives the main clamping member and the auxiliary clamping member to move away from the fixed ring, and the main clamping member and the auxiliary clamping member abut against the inner wall of the cutting groove, and the main material on the workpiece is taken away by the main clamping member and the auxiliary clamping member and separated.

The clamping cylinder can drive the clamping push block to abut against the clamping block and form a clamping hole with the two clamping grooves, and the inner wall of the clamping hole is in pressing contact with the side wall of the workpiece sleeved with the residue.

[0022] By adopting the above technical solution, the clamping push block drives the workpiece on the clamping groove to abut against the clamping block under the drive of the clamping cylinder, and the side wall of the workpiece sleeved with the residue is in pressing contact with the inner wall of the clamping hole, so as to fix the workpiece and wait for the subsequent residue removing step.

[0024] By adopting the above technical solution, the piston rod is controlled by the propulsion cylinder to move towards the communication hole. Since the inner wall of the clamping hole is in pressing contact with the residue remaining on the side wall of the workpiece, the piston rod pushes the workpiece out of the clamping hole and leaves the residue, and the workpiece passes through the communication hole and enters the subsequent process.

A first clamping groove 34 for clamping the workpiece is formed between the first clamping plate 331 and the first fixed seat 33. A torsion spring 332 is arranged at the hinge joint between the first fixed seat 33 and the first clamping plate 331. An elastic rubber rod 333 extending vertically upward is arranged on the first clamping plate 331. The end of the elastic rubber rod 333 away from the first clamping plate 331 can hook and abut against the side wall of the feeding pipe 21, which is used to facilitate the opening of the clamping plate 331 to enlarge the opening of the first clamping groove 34, so as to facilitate the workpiece to fall from the feeding pipe 21 into the first clamping groove 34.

By using the movement of the base of the pushing cylinder 56 to drive the main clamping member 545 and the sub-clamping member 546 to approach the fixed ring 53 and move to the outside of the cutting groove 011 of the workpiece, the main cylinder 541 and the sub-cylinder 542 control the main clamping member 545 and the sub-clamping member 546 to gradually approach and abut, so that the overall formed by the main clamping member 545 and the sub-clamping member 546 is sleeved on the workpiece within the cutting groove 011.

A clamping assembly 71 is fixedly connected to the mounting frame 1. The clamping assembly 71 includes a clamping plate 711; the clamping device includes a clamping cylinder 72 fixedly connected to the clamping assembly 71. The piston rod on the clamping cylinder 72 is arranged vertically. A clamping and pushing assembly 73 is arranged at the end of the piston rod of the clamping cylinder 72. A clamping and pushing block 731 is fixedly connected to the clamping and pushing assembly 73; a clamping block 712 vertically opposite to the clamping and pushing block 731 is fixedly connected to the clamping plate 711. Clamping grooves 7311 vertically opposite to each other are respectively provided at one end of the clamping and pushing block 731 opposite to the clamping block 712. The clamping cylinder 72 can drive the clamping and pushing block 731 to abut against the clamping block 712 and make the two clamping grooves 7311 form a clamping hole whose inner wall is in pressing contact with the side wall of the workpiece. A communication hole 7111 matched with the clamping hole is provided on the clamping plate 711.

[0052] As Figure 8 shown in the figure, the clamping and pushing block 731 is located on one side of the outlet of the second material conveying pipe 67. After the workpiece falls from the outlet of the second material conveying pipe 67, it can fall into the clamping groove 7311; a pushing cylinder 74 is fixedly connected to the clamping assembly 71. The piston rod of the pushing cylinder 74 is located on the side of the clamping block 712 away from the clamping plate 711 and a pushing rod 75 coaxial with the clamping hole is fixedly connected to the end; a fixing rod 76 is fixedly connected between the pushing cylinder 74 and the clamping plate 711. A material removing plate 761 located between the communication hole 7111 and the pushing rod 75 is fixedly connected to the fixing rod 76. A pushing groove 7611 for the pushing rod 75 to pass through is provided on the material removing plate 761. The width of the pushing groove 7611 is smaller than the diameter of the workpiece, so as to prevent the waste material 013 from falling on the piston rod of the pushing cylinder 74.

[0053] AsFigure 2 , Figure 8 As shown in Figure 8 , the conveying mechanism further includes a blanking channel 29 fixedly connected to the side of the clamping plate 711 opposite to the side provided with the clamping block 712. The inlet of the blanking channel 29 is aligned with the communication hole 7111 and is used to convey the workpiece after removing the surplus material 013 to the next process.

[0054] The specific operation process of this embodiment is as follows:

[0055] The workpiece enters from the inlet of the feeding pipeline 21 and falls from the feeding pipeline 21 into a clamping groove 34 of the clamping and pushing mechanism; the clamping and pushing mechanism transports the workpiece to the front side of the cutting mechanism through the first pushing cylinder 32, and the workpiece is pushed against the elastic chuck 44 through the ejecting cylinder 35. The cutting device cuts out an annular cutting groove 011 on the side wall of the workpiece around the surface of the plastic shell; then the first receiving device transports the workpiece processed on the cutting mechanism to the first conveying pipeline 25, and the workpiece moves from the first conveying pipeline 25 to the second clamping groove 28 of the second clamping device. The second pushing cylinder 27 transports the workpiece on the second clamping groove 28 to the front side of the placing seat 51. The piston rod of the material shifting cylinder 55 pushes the workpiece located in front of the placing seat 51 against the fixed ring 53 for fixation. The pushing cylinder 56 and the tightening assembly work together to make the main material 012 on the workpiece be taken away and separated by the main clamping member 545 and the auxiliary clamping member 546. The second receiving device transports the workpiece after removing the main material 012 to the second conveying pipeline 67 and transports it to the clamping groove 7311 on the clamping and pushing block 731. The clamping and pushing block 731 moves and abuts against the clamping block 712 and presses the workpiece against the inner wall of the clamping hole. The advancing cylinder 74 controls its piston rod to push the workpiece onto the blanking channel 29, while the surplus material 013 remains on the piston rod of the advancing cylinder 74. The piston rod of the advancing cylinder 74 retracts and passes through the material removing plate 761, so that the surplus material 013 falls off from the piston rod of the advancing cylinder 74.
