Description

Technical Field

[0001] The invention relates to the field of mining motors, in particular to a rubber-filled mold. Background Art

[0002] In recent years, the domestic and foreign motor markets have increasingly higher requirements for the waterproofness of motors. Due to water and solvents, motion control components are often at risk of corrosion and failure. Motor waterproofing is a key step in solving the problem of hydraulic motor failure. Due to the particularity of the glue pouring position, the motor glue pouring can only be carried out after the stator core is assembled into the base. However, during the glue pouring, the waterproof glue is liquid and then solidifies after cooling, so it is necessary to ensure that the waterproof glue flows according to the predetermined position, and the mold is removed after the waterproof glue solidifies. In addition, because the waterproof glue has a certain viscosity, it is very difficult for workers to remove the mold. Summary of the invention

[0003] In order to solve the above problems, the present invention discloses a rubber-filled mold for explosion-proof motors for mining.

[0004] The specific technical solutions are as follows:

[0005] A mining explosion-proof motor rubber filling tire, comprising a left rubber filling tire and a right rubber filling tire; the left rubber filling tire is used when the motor is lying flat and the left side of the motor is filled with rubber, and the right rubber filling tire is used when the motor is standing upright and the right side of the motor is filled with rubber;

[0006] The left rubber tire includes four first ear plates which are mutually angled at 90 degrees, and the inner sides of the first ear plates are all fixed on the first positioning end; the first positioning end penetrates into the left stator core of the motor and is positioned with the inner diameter of the left stator core of the motor;

[0007] A through hole corresponding to the sealing hole of the left end plate of the motor is arranged on the first ear plate;

[0008] A baffle is arranged outside the first positioning end, and a concave ring groove is arranged inside the baffle. The edge of the concave ring groove is a bevel, and the width of the concave ring groove matches the diameter of the stator; a sealing ring groove is arranged outside the first positioning end, and a sealing ring is arranged inside the sealing ring groove;

[0009] The right rubber tire comprises four second ear plates which are mutually angled at 90 degrees, the inner sides of the second ear plates are all fixed on the second positioning ends, and the second ear plates are provided with through holes corresponding to the sealing holes of the right end plate of the motor;

[0010] The second positioning end goes deep into the inside of the stator core on the right side of the motor and is positioned according to the inner diameter of the stator core on the right side of the motor;

[0011] The right rubber-filled tire is also provided with a rubber-filled tube, the lower end of which is inserted into the motor wire groove, and the upper end of which passes through the clamping hole on the second ear plate.

[0012] The first positioning end is a cone, and the second positioning end is also a cone.

[0013] A reinforcing rib is arranged between the baffle plate outside the first positioning end and the first ear plate.

[0014] When pouring glue on the left side of the motor, pour glue through the glue funnel that is perpendicular to the motor axis.

[0015] The glue-filling tube reserves a wiring channel for the thermal element on the end cover.

[0016] The advantages of the present invention are:

[0017] Because there is a junction box structure on the left side of the motor, horizontal glue pouring can reduce the number of processes while better controlling the glue pouring position and improving the sealing performance, so that the waterproof glue is not easy to leak. Horizontal glue pouring uses a better mold seal to ensure that the sealant does not flow into the stator core. Otherwise, the sealant will accumulate on the bottom side of the stator core, affecting the assembly of the rotor.

[0018] When the glue filling on the left side of the motor is completed, the right side can be filled vertically. The glue filling jig is relatively simple, and even if the sealant leaks, it will flow downward along the axial direction inside the stator core and will not accumulate inside the stator core. When filling the right side with glue, vertical filling is used, which can facilitate the observation of the height of the glue filling and the convenience of taking the jig.

[0019] Therefore, the combination of horizontal glue pouring and vertical glue pouring can ensure the quality of glue pouring and reduce the cost of molds, which effectively solves the problem of motor glue pouring. At the same time, it saves production costs while ensuring the quality of glue pouring. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The specific technical solutions are as follows:

[0027] When the left end of the motor is filled with glue, the motor lies horizontally, and the left port of the motor is sealed by the left glue-filling tire 1; the first positioning end 7 goes deep into the inside of the left stator core of the motor and is positioned by the inner diameter of the left stator core of the motor. The middle part of the first positioning end 7 is a cone 6. This structure makes it convenient to remove the tire after filling with glue. A baffle 8 is set in the left glue-filling tire 1, and this structure seals the glue filling position; a concave ring groove 18 is set inside the baffle 8. The functions of this concave ring groove 18 are: first, to prevent the baffle 8 from interfering with the left side of the stator coil 16 to ensure the glue filling position; second, the inside of the concave ring groove 18 is a slope 6 with rounded corners, which is convenient for removing the tire; there is a sealing ring groove 12 on the outside of the baffle 8, where a sealing ring 13 is placed to improve the sealing of the baffle. Four first ear plates 11 are set at the upper end, and the ear plates 11 are set with positioning holes. The number of the ear plates 11 and the size of the positioning holes 10 correspond to the sealing holes on the left end face of the base; the length of the first ear plate 11 is greater than the outer diameter of the base, which is convenient for taking out the tire after the glue filling is completed; the left glue-filled tire 1 is positioned on the left side of the base through the positioning holes 10 with screws 3, and then glue is poured through the glue filling funnel 4 perpendicular to the motor axis. After the waterproof glue 17 solidifies, unscrew the screws 3, knock on the side of the first ear plate 11, make the left glue-filled tire 1 rotate in the motor, and take out the tire.

[0028] When the right end of the motor is glued, the motor is placed upright, the right port is sealed by the right glue-filling tire 2, and the lower end of the second positioning end 27 penetrates into the inner diameter of the iron core and is positioned with the inner diameter of the stator iron core on the right side of the motor. The middle part of the right glue-filling tire 2 is a second cone 26. This structure can facilitate the tire removal after glue filling. The upper end is also provided with a second ear plate 21. The right glue-filling tire 1 is positioned on the right side of the base with a screw 3 through the positioning hole 10 on the second ear plate 21, and can be used as a handle when removing the tire; one of the second ear plates 21 is provided with a positioning hole 14. Before glue filling, the lower end of the glue-filling tube 5 is placed in the motor wire groove 15, and the upper end is deep into the positioning hole 14 on the second ear plate 21 for positioning. This PVC glue-filling tube 5 is the reserved position for the wiring of the thermistor on the right end cover.

[0029] Preferably, sealing oil is applied to the surface of the tire.
