Description

Technical Field

[0001] This utility model relates to the field of stator testing technology, and in particular to a brushless stator puncture test fixture. Background Technology

[0002] Stator piercing in brushless motors refers to breaking the enamel film on the copper wires with a piercing tool to achieve conductivity between the terminals and the copper wires. This design not only eliminates the tedious step of peeling off the enamel but also effectively prevents oxidation and poor soldering. Furthermore, by flattening the iron core surface, irregular shapes and burrs are eliminated, improving the magnetic permeability and energy efficiency of the stator magnetic circuit.

[0003] In the prior art, such as the patent with publication number CN211239126U, a stator conductor enameling stripping device is disclosed, including a working panel; the working panel is provided with a fixing mechanism and a positioning mechanism, and a U-shaped moving plate that can reciprocate is provided between the fixing mechanism and the positioning mechanism. The lower surface of the U-shaped moving plate is provided with limit guide mechanisms on both the left and right sides, and the limit guide mechanisms are fixed on the working panel. The upper surface of the U-shaped moving plate is provided with scraper mechanisms for stripping the enameling layer of the stator conductor end on both the left and right sides.

[0004] The above structure uses mechanical scraping, which is a cumbersome process and cannot simultaneously pierce the three enameled wires of the stator. It also lacks precision in controlling the degree of piercing and has low efficiency. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a brushless stator puncture test fixture to solve the problems of not being able to puncture the three enameled wires of the stator at the same time, not being able to accurately grasp the degree of puncture of the enamel film, and having low puncture efficiency.

[0006] To achieve the above objectives, this utility model provides a brushless stator puncture test fixture, including a main electric push rod, a clamping plate fixedly installed at the output end of the main electric push rod, a limit block also provided on the main electric push rod, a fixture table fixedly installed on one side of the clamping plate, a main puncture mechanism fixedly installed on one side of the fixture table, and two sets of auxiliary puncture mechanisms fixedly installed at both ends of one side of the fixture table, the two sets of auxiliary puncture mechanisms being located below the main puncture mechanism, the main puncture mechanism and the auxiliary puncture mechanism being used to puncture the stator enameled wire, and the main puncture mechanism and the auxiliary puncture mechanism having a front clamping knife and a side clamping knife respectively inside;

[0007] Both sides of the main piercing mechanism are fixedly installed with mounting seats, and a force-bearing rod is movably installed inside the mounting seat. A force-bearing rod is provided on the top of the secondary piercing mechanism. The mounting seat is inclined, and one side of the mounting seat abuts against the bottom of the force-bearing rod. A lifting platform is fixedly installed at the center of the tooling table, and a locking block corresponding to the front clamping knife and the side clamping knife is fixedly installed on the lifting platform.

[0008] Preferably, the main piercing mechanism includes an auxiliary electric push rod fixedly installed on one side of the tooling table, the output end of the auxiliary electric push rod being fixedly connected to a first mounting block, the positive clamping knife being fixedly installed at the bottom of the first mounting block, and the mounting seat being fixedly installed on one side of the first mounting block.

[0009] Preferably, the secondary puncture mechanism includes two sets of fixing blocks fixedly installed on one side of the tooling table, a second mounting block slidably connected inside the fixing blocks, a side clamping knife fixedly installed on one side of the second mounting block, and a force-bearing rod fixedly installed on the top of the second mounting block.

[0010] Preferably, a limiting pin is provided through the inside of the force-bearing rod and the mounting base, and the mounting base and the force-bearing rod are parallel to each other.

[0011] Preferably, V-grooves are provided on one side of the front clamping knife and the side clamping knife and the opposite side of the locking block, and the front clamping knife and the side clamping knife are the same structural components.

[0012] Preferably, the tooling table has an inverted T-shaped structure, and the tooling table also has three sets of through holes inside, which correspond to the V-shaped grooves.

[0013] The beneficial effects of this utility model are:

[0014] The stator end of the brushless motor is passed through the tooling table, and the enameled wire is positioned in the clamping knife fixed position to be pierced. The main electric push rod drives the tooling table to move downwards and stops at the designated position by the limit block. The limit block ensures the piercing position size of the enameled wire. Then, the main piercing mechanism on the tooling table moves downwards, and the inclined rod moves downwards at the same time, thus contacting the force rod. Under the action of the inclined plane, the inner clamping knife of the secondary piercing mechanism moves inwards, thereby driving the main clamping knife and the two sets of side clamping knives to merge into the fixed position. The main clamping knife and the two sets of side clamping knives engage with the locking block. By merging and engaging the piercing clamping knives, the three enameled wires of the stator are pierced simultaneously, ensuring the consistency of the piercing degree of the enamel film and improving the piercing efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a brushless stator puncture test fixture includes a main electric push rod 1, a clamping plate 3 fixedly installed at the output end of the main electric push rod 1, a limit block 2 also provided on the main electric push rod 1, a fixture table 4 fixedly installed on one side of the clamping plate 3, a main puncture mechanism fixedly installed on one side of the fixture table 4, and two sets of auxiliary puncture mechanisms fixedly installed at both ends of one side of the fixture table 4, the two sets of auxiliary puncture mechanisms being located below the main puncture mechanism. The main puncture mechanism and the auxiliary puncture mechanisms are used to puncture the stator enameled wire, and the main puncture machine... The main piercing mechanism and the auxiliary piercing mechanism are respectively equipped with a main clamping knife 7 and a side clamping knife 10; both sides of the main piercing mechanism are fixedly installed with mounting bases 15, and a force-bearing rod 16 is movably installed inside the mounting base 15. The auxiliary piercing mechanism is equipped with a force-bearing rod 16 at the top. The mounting base 15 is inclined, and one side of the mounting base 15 abuts against the bottom of the force-bearing rod 16; a lifting platform 11 is fixedly installed at the center of the tooling table 4, and a locking block 12 corresponding to the main clamping knife 7 and the side clamping knife 10 is fixedly installed on the lifting platform 11.

[0023] In this embodiment, the stator end of the brushless motor passes through the tooling table 4, and the enameled wire is positioned in the clamping knife fixed position to be pierced. The main electric push rod 1 drives the tooling table 4 to move downward and stops it at a designated position by the limit block 2. The limit block 2 ensures the piercing position size of the enameled wire. Then, the main piercing mechanism on the tooling table 4 moves downward, and the inclined rod 14 moves downward at the same time, thus contacting the force rod 16. Under the action of the inclined plane, the inner clamping knife 10 of the secondary piercing mechanism moves inward, thereby driving the main clamping knife 7 and the two sets of side clamping knives 10 to merge into the fixed position. The main clamping knife 7 and the two sets of side clamping knives 10 are engaged with the locking block 12. By merging and engaging the piercing clamping knives, the three enameled wires of the stator are pierced simultaneously, ensuring the consistency of the piercing degree of the enamel film and improving the piercing efficiency.

[0024] As one implementation method, such as Figure 1 , Figure 2 As shown, the main piercing mechanism includes an auxiliary electric push rod 5 fixedly installed on one side of the tooling table 4. The output end of the auxiliary electric push rod 5 is fixedly connected to a first mounting block 6. The positive clamping knife 7 is fixedly installed at the bottom of the first mounting block 6, and the mounting seat 15 is fixedly installed on one side of the first mounting block 6.

[0025] As one implementation method, such as Figure 1 , Figure 2 As shown, the secondary puncture mechanism includes two sets of fixing blocks 8 fixedly installed on one side of the tooling table 4. A second mounting block 9 is slidably connected inside the fixing block 8. The side clamping knife 10 is fixedly installed on one side of the second mounting block 9, and the force-bearing rod 16 is fixedly installed on the top of the second mounting block 9.

[0026] In this embodiment, when the auxiliary electric push rod 5 on the tooling table 4 moves downward, the inclined rods 14 on both sides of the first mounting block 6 move downward and then contact the force-bearing rod 16. Under the action of the inclined surface, the side clamping knife 10 in the second mounting block 9 moves inward, thereby driving the main clamping knife 7 and the two sets of side clamping knives 10 to merge into a fixed position, ready to be pierced.

[0027] As one implementation method, such as Figure 1 , Figure 2 As shown, a limit pin 17 is provided through the inside of the force-bearing rod 16 and the mounting base 15, and the mounting base 15 and the force-bearing rod 16 are parallel to each other.

[0028] In this embodiment, when it is necessary to pierce two enameled wires of the stator, by removing one set of limiting pins 17, the inclined rods 14 in the mounting base 15 are released from the restriction, causing one set of inclined rods 14 to move upward. When the auxiliary electric push rod 5 on the tooling table 4 moves downward, it cannot contact one set of force rods 16, thereby driving the positive clamping knife 7 and one set of side clamping knives 10 to engage, thus enabling simultaneous piercing of different numbers of stator enameled wires.

[0029] As one implementation method, such as Figure 3 As shown, V-grooves 13 are provided on one side of the front clamping knife 7 and the side clamping knife 10 and the opposite side of the locking block 12. The front clamping knife 7 and the side clamping knife 10 are the same structural components.

[0030] In this embodiment, the three enameled wires of the stator are simultaneously pierced by the engagement of the positive clamping knife 7 and the locking block 12, and the side clamping knife 10 and the locking block 12, under the push of the auxiliary electric push rod 5.

[0031] As one implementation method, such as Figure 1 , Figure 2 and Figure 3 As shown, the tooling table 4 has an inverted T-shaped structure, and three sets of through holes 18 are provided inside the tooling table 4, which correspond to the V-shaped grooves 13.

[0032] In this embodiment, the brushless motor stator end is first passed through the V-groove 13 and the perforation 18, and the enameled wire is in the clamping position to be pierced. Then the clamping is used to pierce it.

[0033] Working principle: In use, the stator end is first passed through the V-groove 13 and the through hole 18, and the enameled wire is in the fixed position of the clamping knife to be pierced. The main electric push rod 1 drives the tooling table 4 to move downward and stops at the designated position by the limit block 2. The limit block 2 ensures the piercing position size of the enameled wire. Then, the auxiliary electric push rod 5 on the tooling table 4 moves downward, and the inclined rods 14 on both sides of the first mounting block 6 move downward and then contact the force rod 16. Under the action of the inclined surface, the side clamping knife 10 in the second mounting block 9 moves inward, thereby driving the main clamping knife 7 and the two sets of side clamping knives 10 to merge into the fixed position. The main clamping knife 7 and the two sets of side clamping knives 10 are engaged with the locking block 12. By merging and engaging the piercing clamping knife, the three enameled wires of the stator are pierced at the same time, ensuring that the degree of piercing of the enamel film is consistent and the piercing efficiency is improved.

[0034] When it is necessary to pierce two enameled wires of the stator, by removing one set of limiting pins 17, the inclined rods 14 in the mounting base 15 are released from the restriction, causing one set of inclined rods 14 to move upward. When the auxiliary electric push rod 5 on the tooling table 4 moves downward, it cannot contact one set of force rods 16, thereby driving the positive clamping knife 7 and one set of side clamping knives 10 to engage, thus enabling the simultaneous piercing of different numbers of stator enameled wires.
