Description
Technical Field
[0001] This utility model relates to the field of geared motor processing technology, specifically to an end grinding mechanism for a geared motor housing. Background Technology
[0002] In the connection between the geared motor and the reducer, the flatness and smoothness of the flange end face directly affect the stability of the connection. If the flange surface is uneven or has defects, the connection may be weak, thus affecting the overall operating efficiency and service life of the machine. Therefore, using a grinder to grind the flange can effectively remove surface unevenness, oxide layer, rust, and other impurities, ensuring that the flange surface meets the design requirements for flatness and smoothness, thereby ensuring a stable connection between the motor and the reducer. The working principle of the grinder is mainly based on the interaction between the abrasive and the workpiece surface. When the motor starts, the grinding head begins to rotate at high speed, and the abrasive rubs against the workpiece surface. The hardness and particle size of the abrasive determine the efficiency of material removal and the effect of surface treatment. By adjusting the pressure and speed of the grinding head, different degrees of grinding can be achieved on the surface of the workpiece. At present, grinding machines are single-station structures, consisting of a worktable and a grinding head. During the grinding process, the workpiece is fixed on the worktable, and the grinding head contacts the workpiece surface through rotation or vibration to achieve surface grinding. Therefore, when clamping or disassembling the geared motor housing to be ground, the equipment needs to be stopped and can only be restarted after the geared motor housing is clamped. This means that in high-intensity production environments, it is impossible to grind multiple workpieces at the same time, and frequent shutdowns will significantly increase the production cycle and reduce the overall production efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0018] Please see Figures 1-5 An embodiment of this utility model provides: an end grinding mechanism for a geared motor housing, including a gantry frame 1, a roller grinder 3 mounted on the top of the gantry frame 1, a dual-axis moving unit 2 mounted on the top of the gantry frame 1 for controlling the X-axis and Z-axis positions of the roller grinder 3, and a base platform 4 fixed at the center of the bottom of the gantry frame 1. A dual-station pneumatic clamping assembly 5 for clamping two geared motor housings is mounted on the top of the base platform 4. A PLC control panel 6 is mounted on one side of the surface of the gantry frame 1. The output terminals of the PLC control panel 6 are electrically connected to the input terminals of the dual-station pneumatic clamping assembly 5, the dual-axis moving unit 2, and the roller grinder 3, respectively.
[0019] The dual-axis moving unit 2 includes an X-axis pulley linear module 201 mounted on the top of the gantry 1, a slide table 202 mounted on the moving end of the X-axis pulley linear module 201, and a connecting frame 203 slidably mounted on the top of the slide table 202. A Z-axis double-rod cylinder 204 for controlling the Z-axis height of the connecting frame 203 is mounted on the top of the slide table 202. The bottom end of the connecting frame 203 is fixedly connected to the top of the roller grinder 3. The Z-axis double-rod cylinder 204 drives the connecting frame 203 and the roller grinder 3 to move along the Z-axis to control the Z-axis height of the roller grinder 3, so that the roller grinder 3 maintains appropriate contact pressure with the flange surface of the geared motor housing.
[0020] When the dual-axis moving unit 2 is working, the X-axis pulley linear module 201 drives the slide table 202, the Z-axis double rod cylinder 204, the connecting frame 203, and the roller grinder 3 to move in the X-axis direction, so that the roller grinder 3 can adjust the X-axis position and move between the two geared motor housings, thereby responding and adjusting quickly and reducing the waiting time of the workpiece during the processing.
[0021] The roller grinder 3 includes a frame 301 mounted at the bottom of the connecting frame 203, a grinding roller 303 rotatably mounted on one side inside the frame 301, and a motor 302 mounted on the inner wall of one side of the frame 301. The drive shaft of the motor 302 extends through to the outside of the frame 301 and is equipped with a belt drive structure 304 for driving the grinding roller 303 to rotate. The motor 302 drives the grinding roller 303 in the frame 301 to rotate through the belt drive structure 304. The grinding roller 303 is used to grind the flange surface of the geared motor housing. The grinding roller 303 provides a uniform grinding effect and is particularly suitable for grinding large-area flat surfaces, ensuring the smoothness and consistency of the workpiece surface.
[0022] The dual-station pneumatic clamping assembly 5 includes a horizontal arm 501 slidably mounted at the front and rear positions of the top of the base 4, two limiting blocks 502 mounted on the opposite outer walls of the two horizontal arms 501, and two symmetrical Y-axis cylinders 503 mounted on the top of the base 4. The top of the piston rod of the Y-axis cylinder 503 is fixedly connected to one side outer wall of the horizontal arm 501. The housing of the geared motor is placed between the two limiting blocks 502 in the Y-axis direction. When the piston rod of the Y-axis cylinder 503 drives the horizontal arm 501 and the limiting block 502 to move in the Y-axis direction, the two limiting blocks 502 move closer to each other and fix the workpiece, thereby providing a uniform and strong clamping force to ensure the stability of the workpiece during the processing.
[0023] A material blowing and chip removal mechanism 7 is installed at one end of the surface of the gantry frame 1. The material blowing and chip removal mechanism 7 includes a cross frame that is slidably installed on the front and rear outer walls of the gantry frame 1, a main air pipe installed on the front and rear outer walls of the cross frame, and several nozzles installed at equal intervals at the bottom of the main air pipe. An X-axis cylinder is installed on one side of the back of the gantry frame 1. The top of the piston rod of the X-axis cylinder is fixedly connected to one end of the cross frame.
[0024] In the blowing and chip removal mechanism 7, the main air pipe is connected to an external air pump through a switch valve. The high-pressure gas generated by the air pump enters the main air pipe and is sprayed downward through the nozzle to remove residual chips on the surface of the workpiece.
[0025] In this embodiment, the operator first places the two geared motor housings to be ground in the clamping area of the dual-station pneumatic clamping assembly 5, ensuring that the flange end face of the workpiece faces the roller grinder 3 to avoid processing errors caused by improper clamping. The operator then starts the dual-station pneumatic clamping assembly 5 via the PLC control panel 6 to simultaneously clamp the two geared motor housings. The operator needs to observe the clamping status to ensure that the dual-station pneumatic clamping assembly 5 can apply clamping force evenly, preventing the workpiece from moving during grinding. The initial position of the roller grinder 3 is set on the PLC control panel 6. The X-axis and Z-axis positions of the roller grinder 3 are adjusted via the dual-axis moving unit 2 to make the roller grinder 3 contact the flange end face of the geared motor housing. After confirming that all settings are correct, the operator starts the grinding process via the PLC control panel 6. The roller grinder 3 maintains appropriate contact pressure with the upper surface of the workpiece flange and performs grinding. During the grinding process, the operator activates the blowing and chip removal mechanism 7 to remove grinding dust and debris from the workpiece surface. After one of the geared motor housings has completed the grinding operation, the dual-axis moving unit 2 drives the roller grinder 3 to continue moving to the position of the next geared motor housing and performs grinding operations until both geared motor housings have completed the grinding operation. At this time, the operation of the roller grinder 3 is stopped through the PLC control panel 6, and the roller grinder 3 is moved back to the initial position through the dual-axis moving unit 2. After ensuring that the dual-axis moving unit 2 and the roller grinder 3 have stopped, the operator releases the clamping of the dual-station pneumatic clamping assembly 5 through the PLC control panel 6 and safely removes the two ground workpieces.
