Abstract
Description
Technical Field
[0001] The utility model relates to the field of motors, in particular to a front cover structure of a motor with multiple fixing holes. Background Art
[0002] A motor, also known as an electric motor, is a device that converts electrical energy into mechanical energy. The working principle of the motor is that the magnetic field acts on the current to make the motor rotate. The front cover of the motor, also known as the front end cover of the motor, is a structure used to close the front end of the motor housing, and at the same time plays a role in limiting the output shaft of the motor.
[0003] When the motor is in use, it often needs to be used in conjunction with a corresponding speed reducer. The input shaft of the speed reducer needs to be fixed to the front cover of the motor while being connected to the output shaft of the motor. When fixing, bolts are often used. Therefore, corresponding fixing holes are often reserved on the current motor end cover. However, the positions of these fixing holes are fixed, resulting in differences in the positions of the fixing holes on the speed reducer and the reserved fixing holes on the motor end cover when fixing different specifications of speed reducers, making it impossible to connect and fix the two, thus resulting in poor applicability of the entire motor end cover.

[0022] The technical solutions of this patent will be further described in detail below in combination with specific implementation modes
[0023] Please refer to Figures 1-4 , a front cover structure of a motor with multiple fixing holes, including a covering mechanism 1. The covering mechanism 1 includes a cover plate 101. A plurality of first fixing holes 104 are arranged in an annular array inside the connecting pipe 102. The first fixing holes 104 are provided for bolts to pass through, so that the cover plate 101 can be fixed to the motor housing by bolts, thereby realizing the installation of the cover plate 101. A plurality of heat dissipation holes 105 are arranged in an annular array inside the cover plate 101. The heat dissipation holes 105 are provided to facilitate ventilation and heat dissipation, thereby improving the heat dissipation effect of the motor. On one side of the cover plate 101, H-shaped plates 107 are symmetrically arranged. Through holes 106 corresponding to the heat dissipation holes 105 are symmetrically arranged inside the two groups of H-shaped plates 107. Filter screens 108 fixedly connected to the H-shaped plates 107 are arranged inside each group of through holes 106. The filter screens 108 are provided to filter the air entering the heat dissipation holes 105, thereby reducing the probability of sundries and dust entering the motor through the heat dissipation holes 105
[0024] On one side of the cover plate 101, limit bolts 109 are symmetrically connected by threads. The two groups of limit bolts 109 are both in contact with the two groups of housing plates 107. The setting of the limit bolts 109 can limit and fix the housing plates 107, so as to facilitate the subsequent disassembly and assembly of the housing plates 107 and the cleaning of the filter screen 108. One end of the cover plate 101 is fixedly connected with a communicating connecting pipe 102. The outer wall of the connecting pipe 102 is fixedly connected with a plurality of reinforcing rib plates 110 in an annular array. Each group of reinforcing rib plates 110 is fixedly connected with the cover plate 101. The setting of the reinforcing rib plates 110 can further connect and fix the cover plate 101 and the connecting pipe 102, thereby improving the connection stability between the cover plate 101 and the connecting pipe 102. The end of the connecting pipe 102 away from the cover plate 101 is fixedly connected with a communicating connecting plate 103, and a connecting mechanism 2. The connecting mechanism 2 includes a plurality of guide rods 201 fixedly connected in an annular array between the cover plate 101 and the connecting plate 103. A rotating rod 202 is movably connected to the outside of each group of guide rods 201. The setting of the guide rods 201 can limit the rotating rod 202, so that the rotating rod 202 can slide or rotate on the rotating rod 202.
[0025] A second fixing hole 205 is formed in the interior of each group of rotating rods 202, and a fixing bolt 206 penetrates through the interior of each group of second fixing holes 205. The setting of the second fixing holes 205 can provide space for the movement of the fixing bolts 206, so that the fixing bolts 206 can move along the interior of the second fixing holes 205, thereby facilitating the adjustment of the positions of the fixing bolts 206 to meet the positions of the screw holes on different specifications of reducers, thus effectively improving the applicability of the entire motor front cover. A connecting bolt 208 penetrates through the outside of each group of fixing bolts 206, and each group of connecting bolts 208 is in contact with each group of rotating rods 202 respectively. The setting of the connecting bolts 208 can isolate the nuts of the fixing bolts 206 from the rotating rods 202, so as to reduce the probability of the nuts of the fixing bolts 206 wearing the rotating rods 202.
[0026] A cushion sleeve 207 penetrates through the outer side of each set of fixing bolts 206 away from the cover plate 101. Each set of cushion sleeves 207 abuts against each set of rotating rods 202 respectively. The setting of the cushion sleeve 207 can abut against the rotating rod 202 and the reducer, so as to play a certain supporting role for the rotating rod 202, and further reduce the probability of deformation of the rotating rod 202. A screw rod 203 fixedly connected to the cover plate 101 and the connecting plate 103 is provided between two adjacent guide rods 201. An abutting ring 209 is provided between the cover plate 101 and the connecting plate 103. When the abutting ring 209 abuts tightly against the rotating rod 202, it can play a limiting role for the rotating rod 202. Each set of guide rods 201 and each set of screw rods 203 penetrate through the abutting ring 209. A propulsion nut 204 is threadedly connected to the outer side of each set of screw rods 203. The setting of the propulsion nut 204 can push the abutting ring 209 to move towards the connecting plate 103 when it is screwed, so as to push the abutting ring 209 to abut tightly against the rotating rod 202.
[0027] During use, the bolt is penetrated through the first fixing hole 104, and then the bolt is screwed into the corresponding screw hole on the motor housing, so as to realize the connection and fixation of the cover plate 101 and the motor housing. When it is necessary to connect and fix the whole motor and the reducer, the output end of the motor can be first butted against the input end of the motor reducer, and then each set of rotating rods 202 is rotated and each set of fixing bolts 206 is moved to adjust the positions of each set of fixing bolts 206 to correspond to the bolt holes of the reducer. Then each set of fixing bolts 206 is screwed and fixed to the reducer. Then, a wrench is used to screw each set of propulsion nuts 204, so that the propulsion nuts 204 move towards the side of the connecting plate 103, thereby pushing the rotating rod 202 to move towards the side of the connecting plate 103 accordingly until the abutting ring 209 and the connecting plate 103 both abut tightly against each set of rotating rods 202, so as to realize the fixation of each set of rotating rods 202, and further complete the connection between the motor and the reducer.
[0028] The above - mentioned embodiments are the preferred embodiments of the present utility model, which are only used to conveniently illustrate the present utility model and do not impose any form of limitation on the present utility model. Any person with ordinary knowledge in the technical field concerned, without departing from the technical features proposed by the present utility model, uses the equivalent embodiments obtained by making partial changes or modifications to the technical content disclosed by the present utility model and without departing from the technical feature content of the present utility model, still belongs to the scope of the technical features of the present utility model.
