Description

Technical Field

[0001] The utility model relates to the technical field of reducer production equipment, in particular to an auxiliary assembly device for a reducer electromagnetic coil. Background Art

[0002] During the assembly process of the electromagnetic coil of the reducer, it is necessary to align the electromagnetic coil with the housing and fit the electromagnetic coil into the housing.

[0003] The problem with the existing technology is that during the assembly process, since the size of the inner hole of the shell is close to that of the electromagnetic coil, the electromagnetic coil is very likely to scratch or get stuck with the inner hole wall of the shell during assembly, causing wear of the electromagnetic coil; moreover, in order to avoid the above-mentioned wear problem, inserting the electromagnetic coil in a horizontal posture will cause friction on one side, so it is usually assembled by a vertical posture coaxial drop method. As a result, the operator not only needs to pay attention to maintaining the coaxial center during the assembly of the two, but also needs to control the electromagnetic drop speed and force to avoid excessive impact force during the drop assembly and damage to the electromagnetic coil, resulting in the entire assembly process being more time-consuming and labor-intensive.

[0004] Therefore, it is necessary to design an auxiliary assembly device for electromagnetic coils to overcome the above problems and improve the assembly yield and efficiency. Utility Model Content

[0005] In order to solve the deficiencies of the above-mentioned technology, the utility model provides an auxiliary assembly device for the electromagnetic coil of a speed reducer.

[0006] The utility model is further provided with: an auxiliary assembly device for a reducer electromagnetic coil, the reducer including a housing and an electromagnetic coil, the assembly device including a base and a rotating arm, the rotating arm including a hinged end, a heating section, and a sleeve end, the hinged end and the base being rotated in a horizontal direction, the base corresponding to the rotation path of the sleeve end, being provided with a support platform, and the support platform being provided with a contact switch or an induction switch;

[0007] The profile of the heating section of the rotating arm is adapted to the inner hole diameter of the casing. The casing enters the heating section from the insertion end. A heating component is provided in the heating section. The heating component is connected to the contact switch or induction switch signal and opens and closes the heating casing according to the rotation position of the insertion end.

[0008] By adopting the above technical solution and setting the above device, before the casing and the electromagnetic coil are assembled, the casing is first inserted into the heating section from the insertion end, and heated by the heating components arranged in the heating section, such as the heating coil and the heating tube. The heating section can be provided with a flexible thermal conductive pad to transfer heat to the inner hole of the casing, causing it to produce a thermal expansion effect, and the provision of a flexible thermal conductive pad can avoid wear on the inner hole wall; after the casing produces a certain thermal expansion due to heating, the size of the inner hole is expanded to a certain extent, which makes the coaxial assembly process of the electromagnetic coil more convenient, reduces wear, and the casing returns to normal after natural cooling.

[0009] The contact switch or induction switch provided on the support platform of the device identifies the position of the rotating arm. Only when the rotating arm is at the support platform will the heating component be turned on according to the signal, otherwise it will be turned off, ensuring the safety of the device during use.

[0010] The utility model is further configured as follows: a limit baffle is provided on one side of the heating section of the rotating arm close to the hinged end, and an electromagnet is provided at the limit baffle. The electromagnet is connected to the contact switch or the induction switch signal, and opens and closes the fixed housing according to the rotation position of the inserted end.

[0011] Using the above technical solution, the casing is usually a cast iron part, and its components can be attracted by the electromagnet. When the worker puts the casing into the casing, the casing is at a random position in the heating section, which will cause the heating component to fail to fully and adequately heat the casing. Therefore, the limit baffle is used to control the extreme position of the front end of the heating section. Before the rotating arm reaches the support platform position and the heating component is started, the electromagnet is started first to attract the casing at a random position on the heating section to be adsorbed on the limit baffle, so that its position is fixed and sufficient heating is ensured.

[0012] The utility model is further configured as follows: the axial length of the heating section is adapted to the axial length of the casing, including a head end close to one side of the limit baffle and an end end on the other side; the base support platform and the heating section rotation path do not interfere with each other, and a groove is provided on the side facing the heating section.

[0013] By adopting the above technical solution, through the structural design of the support table position and the groove, when the worker inserts the casing into the position beyond the heating section, the casing will clash with the support table and cannot be closed during the process of returning to the closing position with the rotating arm, thereby achieving a reminder function.

[0014] Further configuration of the present invention: the device also includes a buffer base, which includes an insertion shaft and a support flange. The diameter of the insertion shaft is adapted to the diameter of the inner hole of the casing, and is inserted into the inner hole of the casing in a vertical posture. The support flange rests against the end face vertically below the casing, and an elastic pad is provided on the surface of the buffer base.

[0015] By adopting the above technical solution, the installation position and posture of the casing are fixed by setting the buffer base, and the impact force when the electromagnetic coil falls is guided and received, thereby avoiding the loss of accessories during the assembly process.

[0016] The present invention is further provided with: the base is provided with a rotating shaft and a rotating shaft driving mechanism, the rotating shaft is hingedly connected to a rotating arm, the rotating arm includes a closed position for contacting a contact switch or an inductive switch, and an open position for flipping away from the base, the rotating shaft driving mechanism drives the rotating arm to rotate back and forth at equal angles between the closed position and the open position;

[0017] The device also includes a shell feeding conveyor line, a loading robot, an electromagnetic coil feeding conveyor line, an assembly robot, a unloading robot, and a discharging conveyor line. The feeding conveyor line inputs the shell in steps, the loading robot clamps the shell and is connected to the rotating arm heating section of the opening station; the assembly robot clamps the heated shell and is connected to the buffer base in a fixed position, and clamps the electromagnetic coil to assemble it into the shell, and the unloading robot clamps the assembled shell to the discharging conveyor line.

[0018] By adopting the above technical solution, under the above structural design and safety design, manual operation is convenient and safe, and it can be combined with automatic feeding and robotic equipment to further optimize the equipment and assembly process. By utilizing the characteristics of the above device to guide the casing, determine the coordinates, and automatically heat the casing, and further setting up the rotating shaft drive mechanism, the open and closed work stations can be controlled to obtain the exact coordinates of several states of the casing, and cooperate with the robotic arm to complete automated loading, unloading, assembly and other tasks.

[0019] The beneficial effects of the present invention are as follows: by setting the heating and assembly buffer seat of the casing through the device of the present application, scratching, jamming, impact and other losses during the assembly process of the electromagnetic coil and the casing are avoided, the assembly difficulty is simplified, and the assembly efficiency is improved.

[0026] The present invention is described in detail below with reference to the accompanying drawings. Figure 1-3 As shown,

[0027] An auxiliary assembly device for a reducer electromagnetic coil 2, the reducer including a housing 1 and an electromagnetic coil 2, the assembly device including a base 31 and a rotating arm 4, the rotating arm 4 including a hinged end 41, a heating section 42, and a sleeve end 43, the hinged end 41 and the base 31 rotating in a horizontal direction, the base 31 corresponding to the rotation path of the sleeve end 43, and provided with a support platform 32, the support platform 32 being provided with a contact switch 33 or an induction switch 33;

[0028] The profile of the heating section 42 of the rotating arm 4 is adapted to the inner diameter of the housing 1. The housing 1 enters the heating section 42 from the insertion end 43. A heating component is provided in the heating section 42. The heating component is connected to the contact switch 33 or the induction switch 33 signal, and the heating housing 1 is opened and closed according to the rotation position of the insertion end 43.

[0029] Through the arrangement of the above-mentioned device, before the casing 1 and the electromagnetic coil 2 are assembled, the casing 1 is first inserted into the heating section 42 from the insertion end 43, and heated by the heating components arranged in the heating section 42, such as the heating coil and the heating tube. The heating section 42 can be provided with a flexible thermal pad to transfer heat to the inner hole of the casing 1, so that it produces a thermal expansion effect, and the provision of the flexible thermal pad can avoid wear of the inner hole wall; after the casing 1 produces a certain thermal expansion after heating, the size of the inner hole is expanded to a certain extent, which makes the coaxial assembly process of the electromagnetic coil 2 more convenient, reduces wear, and the casing 1 returns to normal after natural cooling.

[0030] The contact switch 33 or induction switch 33 provided on the support platform 32 of the device identifies the position of the rotating arm 4. Only when the rotating arm 4 is at the support platform 32, the heating component is turned on according to the signal, otherwise it is turned off, ensuring the safety of the device during use.

[0031] The rotating arm 4 is provided with a limit baffle 44 on one side of the heating section 42 close to the hinge end 41, and an electromagnet 45 is provided on the limit baffle 44. The electromagnet 45 is connected to the contact switch 33 or the induction switch 33 signal, and opens and closes the fixed housing 1 according to the rotation position of the inserted end 43.

[0032] The casing 1 is usually a cast iron part, and its components can be attracted by the electromagnet 45. When the worker puts the casing 1 into the casing 1, the casing 1 is at a random position in the heating section 42, which will cause the heating component to fail to fully and adequately heat the casing 1. Therefore, the limit baffle 44 is used to control the extreme position of the front end of the heating section 42. Before the rotating arm 4 reaches the support platform 32 and the heating component is started, the electromagnet 45 is started first to attract the casing 1 at a random position on the heating section 42 to be adsorbed on the limit baffle 44, so that its position is fixed and sufficient heating is ensured.

[0033] The axial length of the heating section 42 is adapted to the axial length of the casing 1, including the head end on one side close to the limit baffle 44 and the end on the other side. The rotation paths of the base 31 support platform 32 and the heating section 42 do not interfere with each other, and a groove 34 is provided on the side facing the heating section 42.

[0034] Through the structural design of the support platform 32 position and the groove 34, when the worker inserts the casing 1 too far beyond the heating section 42, the casing 1 will collide with the support platform 32 and cannot be closed during the process of returning to the closing position with the rotating arm 4, thereby achieving a reminder function.

[0035] The device also includes a buffer base 5, which includes an insertion shaft 51 and a support flange 52. The diameter of the insertion shaft 51 is adapted to the diameter of the inner hole of the casing 1, and is inserted into the inner hole of the casing 1 in a vertical posture. The support flange 52 rests against the end face vertically below the casing 1, and an elastic cushion layer is provided on the surface of the buffer base 5.

[0036] By setting the buffer base 5, the installation position and posture of the housing 1 are fixed, and the impact force of the electromagnetic coil 2 when it falls is guided and received, thereby avoiding the loss of accessories during the assembly process.

[0037] The machine base 31 is provided with a rotating shaft and a rotating shaft driving mechanism, which is hingedly connected to the rotating arm 4. The rotating arm 4 includes a closing position that contacts the contact switch 33 or the induction switch 33, and an opening position that flips away from the machine base 31. The rotating shaft driving mechanism drives the rotating arm 4 to rotate back and forth at equal angles between the closing position and the opening position; the device also includes a shell feeding conveyor line, a loading robot, an electromagnetic coil 2 feeding conveyor line, an assembly robot, a unloading robot, and a discharging conveyor line. The feeding conveyor line stepwise inputs the shell 1, the loading robot clamps the shell 1, and is sleeved to the heating section 42 of the rotating arm 4 at the opening position; the assembly robot clamps the heated shell 1 and sleeves it on the buffer base 5 in a fixed position, and clamps the electromagnetic coil 2 to assemble it into the shell 1, and the unloading robot clamps the assembled shell 1 to the discharging conveyor line.

[0038] Under the above structural design and safety design, manual operation is convenient and safe, and at the same time, it can be combined with automatic feeding and manipulator equipment to further optimize the equipment and assembly process. By utilizing the characteristics of the above device to guide the casing 1, determine the coordinates, and automatically heat it, after further setting up the rotating shaft drive mechanism, the open and closed work stations can be controlled to obtain the exact coordinates of several states of the casing 1, and cooperate with the manipulator to complete automated loading, unloading, assembly and other tasks.

[0039] By setting the heating and assembly buffer seat of the casing 1 in the device of the present application, scratching, jamming, impact and other losses during the assembly process of the electromagnetic coil 2 and the casing 1 are avoided, the assembly difficulty is simplified, and the assembly efficiency is improved.
