Description

Technical Field

[0001] The invention relates to the technical field of material deformation, and in particular to a mechanism for preventing Z-axis movement based on internal support positioning of a motor stator core. Background Art

[0002] The motor stator core is an important part of the motor magnetic circuit. It, together with the rotor core and the air gap between the stator and the rotor, forms the complete magnetic circuit of the motor. In an asynchronous motor, the magnetic flux in the stator core is alternating, thus generating core loss. The core loss consists of two parts: hysteresis loss and eddy current loss. During the production and processing of the motor stator core, a positioning mechanism is required to position and fix the motor stator core.

[0003] The inventors have found that there are at least the following problems in the prior art that have not been solved: in the production process of the motor stator core, a positioning mechanism is used to position and fix the motor stator core. During the processing, the motor stator core is prone to Z-axis movement, resulting in poor fixing effect of the motor stator core by the positioning mechanism, thereby affecting the processing quality of the motor stator core and reducing the production and processing efficiency of the motor stator core; and the fixing method of the motor stator core is not convenient enough, and the motor stator core cannot be quickly disassembled and assembled; therefore, we propose a mechanism for preventing Z-axis movement based on the internal support positioning of the motor stator core. Summary of the invention

[0004] The main purpose of the present invention is to provide a mechanism for preventing Z-axis movement based on the internal support positioning of the motor stator core, which can effectively solve the problems in the background technology.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] The mechanism for preventing Z-axis movement based on the internal support positioning of the motor stator core includes a tooling plate, a product positioning block is installed in the middle of the upper end of the tooling plate, a piston rod is inserted and movably connected to the middle of the upper end of the product positioning block, a spring is sleeved on the lower part of the outer surface of the piston rod, a soft sealing ring is sleeved on the upper part of the outer surface of the piston rod, a sealing ring clamping block is inserted and fixedly connected to the middle of the upper end of the piston rod, a ventilation mechanism is installed in the middle of the lower end of the product positioning block, and mounting holes are opened at the upper front, upper rear, upper left and upper right of the tooling plate.

[0007] As a further improvement of the above solution, a mounting groove is opened in the middle of the upper end of the tooling plate, a rubber ring is fixedly connected to the side groove walls of the mounting groove, and a product body is installed in the middle of the upper end of the product positioning block.

[0008] As a further improvement of the above solution, a placement groove is opened in the middle of the upper end of the product positioning block, and a storage groove is opened in the middle of the lower end of the product positioning block. A first sealing ring is inserted and fixedly connected to the lower part of the inner groove wall of the storage groove.

[0009] As a further improvement of the above scheme, two limit strips are fixedly connected to the upper part of the outer surface of the piston rod, a positioning groove is opened in the middle part of the lower end of the piston rod, a positioning socket is clamped in the positioning groove, a push plate is fixedly connected to the lower end of the positioning socket, and a small sealing ring is sleeved on the lower part of the outer surface of the piston rod.

[0010] As a further improvement of the above solution, the diameter length of the push plate is consistent with the diameter length of the storage groove, and the small sealing ring and the first sealing ring are both configured as O-type structures.

[0011] As a further improvement of the above scheme, the ventilation mechanism includes a ventilation block, a sealing groove is opened on the upper part of the outer surface of the ventilation block, a second sealing ring is clamped in the sealing groove, a ventilation hole is opened in the middle part of the upper end of the ventilation block, an air inlet hole is opened in the lower right end of the ventilation block, and four connecting holes are opened on the upper end of the convex ring in the middle part of the outer surface of the ventilation block, and the ventilation block is fixedly connected to the lower end of the product positioning block through the four connecting holes.

[0012] As a further improvement of the above solution, the diameter length of the upper end surface of the ventilation block is consistent with the diameter length of the storage groove, the second sealing ring is configured as an O-type structure, and the interior of the ventilation hole is connected to the interior of the air inlet hole.

[0013] As a further improvement of the above scheme, the upper part and the lower part of the inner ring wall of the soft sealing ring are both provided with limit slots, the two limit slots are respectively connected with two limit strips, and the cross-sections of the limit slots and the limit strips are both set to be two triangles.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, a piston rod and a spring are provided, and the push plate is pushed downward by the elasticity of the spring. The thrust generated causes the piston rod to move the sealing ring pressing block downward to compress and fix the soft sealing ring. At this time, the pressure causes the soft sealing ring to generate pressure extrusion in the Z-axis direction, causing the soft sealing ring to deform and position and fix the product internally, thereby improving the stability of the product and ensuring that the product is not affected by the Z-axis movement, thereby improving the processing quality of the motor stator core and also improving the work efficiency.

[0016] 2. In the present invention, by setting a ventilation mechanism, the sealing performance between the ventilation block and the product positioning block can be enhanced by the second sealing ring, so that the storage groove in the product positioning block can form a sealed cavity, and then gas is input into the ventilation hole through the air inlet hole. The pressure of the gas causes the push plate to push the piston rod upward, which can offset the force output by the spring, so that the sealing ring clamping block can cancel the squeezing of the soft sealing ring, thereby achieving the purpose of quickly releasing the product and facilitating the rapid disassembly and assembly of the product.

[0030] A mounting groove 9 is provided in the middle of the upper end of the tooling plate 1 , and a rubber ring 10 is fixedly connected to the side groove walls of the mounting groove 9 . A product body 11 is installed in the middle of the upper end of the product positioning block 2 .

[0031] A placement groove 21 is formed in the middle of the upper end of the product positioning block 2 , and a receiving groove 22 is formed in the middle of the lower end of the product positioning block 2 . A first sealing ring 23 is inserted and fixedly connected to the lower part of the inner groove wall of the receiving groove 22 .

[0032] Two limit clamping strips 31 are fixedly connected to the upper part of the outer surface of the piston rod 3, a positioning groove 32 is opened in the middle of the lower end of the piston rod 3, a positioning clamping seat 33 is clamped in the positioning groove 32, a push plate 34 is fixedly connected to the lower end of the positioning clamping seat 33, and a small sealing ring 35 is sleeved on the lower part of the outer surface of the piston rod 3; the diameter length of the push plate 34 is consistent with the diameter length of the storage groove 22, and the small sealing ring 35 and the first sealing ring 23 are both set to O-type structure, which can enhance the sealing effect.

[0033] The ventilation mechanism 5 includes a ventilation block 51, a sealing groove 52 is opened on the upper part of the outer surface of the ventilation block 51, a second sealing ring 53 is clamped in the sealing groove 52, a ventilation hole 54 is opened in the middle of the upper end of the ventilation block 51, an air inlet hole 55 is opened at the lower right end of the ventilation block 51, and four connecting holes 56 are opened on the upper end of the convex ring in the middle of the outer surface of the ventilation block 51. The ventilation block 51 is fixedly connected to the lower end of the product positioning block 2 through the four connecting holes 56; the diameter length of the upper end surface of the ventilation block 51 is consistent with the diameter length of the storage groove 22, the second sealing ring 53 is set to an O-type structure, which can seal the storage groove 22, so that the storage groove 22 forms a sealed cavity, which can further enhance the sealing effect, the interior of the ventilation hole 54 is connected with the interior of the air inlet hole 55, and the gas can be input into the ventilation hole 54 through the air inlet hole 55.

[0034] The upper and lower parts of the inner ring wall of the soft sealing ring 6 are both provided with limit slots 61, and the two limit slots 61 are respectively engaged with the two limit strips 31. The cross-sections of the limit slots 61 and the limit strips 31 are both set to be two triangles, so that the limit slots 61 and the limit strips 31 are firmly engaged.

[0035] In summary, during the use of the present invention, the product body 11 to be processed is first placed in the placement groove 21.

At this time, the pressure generated by the clamping applies pressure to the soft sealing ring 6 in the Z-axis direction, causing the soft sealing ring 6 to deform, thereby expanding its diameter in the longitudinal direction, thereby internally supporting and holding the product body 11. The internal support positions and fixes the product body 11 firmly, which can improve the stability of the product body 11 and ensure that the product body 11 is not affected by the Z-axis movement, thereby improving the processing quality of the motor stator core and improving the work efficiency. After the product positioning block 2 is processed, gas can be input into the vent 54 through the air inlet 55 to make the gas Entering into the receiving groove 22, at this time, the sealing performance between the ventilation block 51 and the product positioning block 2 can be strengthened by the second sealing ring 53, so that the receiving groove 22 in the product positioning block 2 forms a sealed cavity, which can prevent the gas from escaping from the receiving groove 22. At this time, the push plate 34 can be pushed upward by the input gas pressure, so that the push plate 34 pushes the piston rod 3 upward, and the spring 4 contracts to reduce the force on the soft sealing ring 6, which can offset the force output by the spring 4. At the same time, the piston rod 3 pushes the sealing ring clamping block 7 to move upward, which can cancel the squeezing and fixing of the soft sealing ring 6, and make the soft sealing ring 6 rebound to release the product body 11, thereby achieving the purpose of quickly releasing the product body 11, which can facilitate the quick disassembly and assembly of the product body 11, and when the ventilation block 51 has no air intake, the soft sealing ring 6 is compressed to an expanded state by the spring 4.
