Description

Technical Field

[0001] The utility model relates to the technical field of pressing machines, in particular to a hydraulic tooling fixture for machining motor shells. Background Art

[0002] An electric motor, commonly known as a motor, is a power machine that converts electrical energy into mechanical energy by using the interaction between a magnetic field and a current-carrying conductor. [1] In 1821, the experimental model developed by Faraday of England to make a charged conductor rotate around a vertical magnet was the "prototype" of the modern electric motor. In 1860, the direct current motor with a ring-shaped armature invented by Pachinochi of Italy basically possessed the structural form of the modern direct current motor.

[0003] There are some shortcomings in the prior art when pressing the motor casing: first, the existing pressing machine will also impact the pressing operation table while pressing the motor casing. After a long period of pressing, the pressing table is likely to be damaged, affecting the service life of the equipment. Second, since there are many components inside the motor that need to be pressed, different pressing molds need to be replaced when pressing different parts. At present, the molds are usually fixed to the pressing machine by bolts, which makes it more troublesome to replace the pressing molds. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a hydraulic fixture for machining a motor housing, which solves the problem of a short service life of a pressing table.

[0005] The utility model provides the following technical solutions: a hydraulic fixture for machining a motor housing,

[0006] Preferred technical solution one: comprises a frame, wherein two sides of the top of the frame are fixedly connected with a fixed frame, the top of the fixed frame is fixedly connected with a hydraulic pump, the top inner cavity of the frame is fixedly connected with a pressing table, the bottom end of the hydraulic pump is fixedly connected with a push rod, the bottom end of the push rod is provided with a pressing mold, the top of the pressing table is provided with a pressing chamber, the pressing chamber is located directly below the pressing mold, the bottom of the inner cavity of the pressing chamber is provided with five mounting grooves, the inner cavity of the mounting groove is fixedly connected with a pressure reducer, the inner cavity of the pressing mold is fixedly connected with four connecting parts, the outer side of the pressing mold is provided with a movable groove, the inner wall of the movable groove is movably connected with a movable ring, the inner wall of the movable ring is fixedly connected with four positive magnets, and the outer side of the bottom end of the push rod is provided with four embedding holes.

[0007] This solution can reduce the impact force received by the pressing table, making the equipment more stable during operation, while providing protection for the pressing machine and increasing the service life of the pressing machine.

[0008] Preferred technical solution two: the pressure reducer includes an oil storage tank, the inner cavity of the oil storage tank is movably connected with a pressure reducing plate, the top of the inner cavity of the oil storage tank is fixedly connected with a sealing cover, the top of the pressure reducing plate is fixedly connected with a lifting rod, the top of the sealing cover is fixedly connected with a fixed plate, the top of the fixed plate is fixedly connected with a No. 2 spring, the top of the lifting rod is fixedly connected with a pressure cover, a number of oil filter holes are provided on the surface of the pressure reducing plate, and the inner cavity of the oil storage tank is filled with shock-absorbing oil.

[0009] This solution can make the pressing mold of the pressing machine easier to disassemble and install, greatly improve the speed of replacing the mold, and thus increase the efficiency of the pressing work.

[0010] Preferred technical solution three is that: the connecting part includes a sleeve, one end of the inner cavity of the sleeve is movably connected with an embedded block, the other end of the inner cavity of the sleeve is fixedly connected with a No. 3 spring, one end of the embedded block is fixedly connected with a negative magnet, and the corresponding surfaces of the negative magnet and the positive magnet attract each other.

[0011] This solution is advantageous in that when the positive magnet moves to the rear of the negative magnet, the negative magnet drives the embedded block to move backward under the action of suction, and the No. 3 spring is squeezed when the embedded block moves backward, causing it to deform. Therefore, when the positive magnet leaves the rear of the negative magnet, the No. 3 spring loses pressure and lifts the embedded block back to its original position.

[0012] Preferred technical solution four: an anti-dropout sleeve is fixedly connected to the outer side of the embedding block, an anti-dropout groove is provided on the inner wall of the sleeve, and the anti-dropout sleeve and the anti-dropout groove are adapted to each other.

[0013] This solution can be advantageous in that when the embedded block moves forward and backward along the inner wall of the sleeve, the anti-slip sleeve also moves forward and backward along the inner wall of the anti-slip groove, thereby preventing the embedded block from escaping from the inner cavity of the sleeve.

[0014] Preferred technical solution five: The outer side of the bottom end of the sealing cover is interference fit with the inner wall of the oil storage tank.

[0015] This solution can help prevent the shock absorber in the oil storage tank from leaking from the connection between the oil storage tank and the sealing cover.

[0016] Preferred technical solution six: Three No. 1 springs are fixedly connected to both sides of the top of the inner cavity of the pressing chamber, and one end of each No. 1 spring is fixedly connected to a clamping block.

[0017] This solution can be advantageous in that the motor or its parts to be pressed can be clamped in the inner cavity of the pressing table by two clamping blocks, thereby avoiding displacement of the position thereof during pressing.

[0019] 1. In the utility model, by setting a pressure reducer, the impact force and reaction force generated by the motor housing during pressing can be reduced, and the impact force received by the pressing table can be reduced, so that the equipment is more stable during operation, and at the same time, the pressing machine is protected, so that the service life of the pressing machine is increased;

[0020] 2. In the utility model, a movable ring is provided, and when the movable ring is rotated to move the positive magnet to the rear of the connecting piece, the pressing mold can be removed from the bottom of the push rod. At the same time, when the positive magnet is moved away from the rear of the connecting piece, the pressing mold can be installed on the bottom end of the push rod through the connecting piece, making the pressing mold of the pressing machine easier to disassemble and install, greatly improving the speed of replacing the mold, thereby increasing the efficiency of the pressing work.

[0030] The connecting member 7 includes a sleeve 71, one end of the inner cavity of the sleeve 71 is movably sleeved with an embedding block 72, the other end of the inner cavity of the sleeve 71 is fixedly connected to a No. 3 spring 73, and one end of the embedding block 72 is fixedly connected to a negative magnet 74. The corresponding surfaces of the negative magnet 74 and the positive magnet 63 attract each other, which is beneficial when the positive magnet 63 moves to the rear of the negative magnet 74. Under the action of suction, the negative magnet 74 drives the embedding block 72 to move backward, and the No. 3 spring 73 is squeezed when the embedding block 72 moves backward to cause it to deform, so that when the positive magnet 63 leaves the rear of the negative magnet 74, the No. 3 spring 73 loses pressure and lifts the embedding block 72 to return to its original position.

[0034] Working principle of this utility model:

[0035] Step 1, in the utility model, a pressing table 4 is provided, and the motor housing to be pressed is fixed in the inner cavity of the pressing chamber 41, and the hydraulic pump 3 is used to give power to move the push rod 31 downward, and the pressing mold 6 is moved downward by the push rod 31 moving downward, and the component is pressed by the pressing mold 6. During the pressing, the component receives pressure, so that the pressure reducer 5 receives pressure, and the pressure cover 57 is moved downward by the pressure cover 57, and the lifting rod 54 is moved downward by the pressure cover 57, and the second spring 56 is squeezed and deformed by the pressure cover 57 moving downward, and the lifting rod 54 is moved downward to move the pressure relief plate 52 downward along the inner cavity of the oil storage tank 51. Since the inner cavity of the oil storage tank 51 is equipped with a shock absorber, when the pressure relief plate 52 moves downward, the squeeze The shock absorber oil is compressed, so that the shock absorber oil is squeezed out to the top of the pressure reducing plate 52 through the oil filter hole 58, generating a damping force, slowing down the downward movement speed of the pressure reducing plate 52, and slowing down the downward movement speed of the pressure cover 57 through the pressure reducing plate 52, and the impact force generated by the pressing is buffered by the slow downward movement speed of the pressure cover 57. When the impact force disappears, the second spring 56 loses pressure and returns to its original state, thereby lifting the pressure cover 57 to move upward, and the pressure reducing plate 52 moves upward through the upward movement of the pressure cover 57, and the shock absorber oil flows back through the oil filter hole 58 through the upward movement of the pressure reducing plate 52, generating a damping force, thereby slowing down the upward movement speed of the pressure reducing plate 52, and slowing down the upward movement speed of the pressure cover 57 through the pressure reducing plate 52, thereby alleviating most of the reaction force;

[0036] Step 2, in the utility model, a pressing mold 6 is provided, and the pressing mold 6 includes a movable ring 62. The movable ring 62 is rotated by an external force to rotate along the inner wall of the movable groove 61. When the movable ring 62 rotates, the position of the positive magnet 63 is changed. When the positive magnet 63 moves to the rear of the connecting member 7, the negative magnet 74 and the corresponding surfaces of the positive magnet 63 attract each other, so that the positive magnet 63 attracts the negative magnet 74 to move backward, and the negative magnet 74 moves backward to move the embedded block 72 backward. When the embedded block 72 moves backward, it leaves the inner cavity of the embedded hole 32, so that the pressing mold The connection between the tool 6 and the push rod 31 is disconnected. At this time, the pressing mold 6 can be removed for replacement. During installation, the pressing mold 6 is installed into the bottom end of the push rod 31. The outer side of the push rod 31 squeezes the embedding block 72 to make it move backward. The embedding block 72 moves backward to squeeze the No. 3 spring 73 to cause it to deform. As the connecting piece 7 is moved to the front of the embedding hole 32, the No. 3 spring 73 loses pressure and returns to its original state, thereby lifting the embedding block 72 to move it forward and back to its original position. The embedding block 72 moves forward to make it enter the inner cavity of the embedding hole 32 again, so that the connecting piece 7 is fixed to the bottom end of the hydraulic pump 3.
