However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] like Figure 1-Figure 4 As shown, the utility model provides a grinding device for ball screw processing, comprising: a grinding mechanism 1, on which a protection mechanism 2 is arranged;

[0025] The protective mechanism 2 includes a main shell 201, an auxiliary shell 202 and four limit slots 205. A connecting block 203 is fixed to one side of the auxiliary shell 202 and to the side of the main shell 201 away from the auxiliary shell 202. The tops of the two connecting blocks 203 are movable through the limit blocks 204. The bottoms of the two clamping ends of each limit block 204 and the bottoms of the inner walls of each limit slot 205 are fixedly embedded with magnetic buckles 206. The main shell 201 and the auxiliary shell 202 are adapted to each other. The four limit slots 205 is divided into two groups, the two clamping ends of each limit block 204 are respectively located inside each group of limit slots 205, eight magnetic buckles 206 are grouped in two vertical directions, and the opposite side of each group of magnetic buckles 206 is connected by a magnetic pole. The grinding mechanism 1 includes a box body 101, a workbench 102 is fixed on the top of the box body 101, and the four limit slots 205 are all opened on the upper side of the workbench 102. The bottom of the main shell 201 and the bottom of the auxiliary shell 202 are both connected to the upper side of the workbench 102. The top of the workbench 102 is provided with a clamping rotating assembly 103, the upper side of the workbench 102 is provided with a first rectangular block 104, the top of the first rectangular block 104 is provided with a slide groove 105, the bottom of the inner wall of the slide groove 105 is provided with an electric push rod 106, the inside of the slide groove 105 is slidably connected with a slider 107, the inside of the slide groove 105 is slidably connected with a second rectangular block 108, the top of the second rectangular block 108 is fixed to the top of the slider 107, and the slider A motor 109 is installed on the top of 107, and a grinding wheel 110 is installed on the output end of the motor 109. The grinding wheel 110 and the clamping rotating end of the clamping rotating assembly 103 are both located between the interior of the main shell 201 and the interior of the auxiliary shell 202. A controller 111 is installed on one side of the workbench 102, the clamping rotating assembly 103 is electrically connected to the controller 111, the motor 109 is electrically connected to the controller 111, and the electric push rod 106 is electrically connected to the controller 111.

[0026] The effect achieved is that when it is necessary to grind the screw shaft end of the ball screw, the screw shaft end of the ball screw is first fixed by using the cooperation of the controller 111 and the clamping rotating assembly 103, and then the motor 109 is driven to move by using the cooperation of the controller 111, the first rectangular block 104, the second rectangular block 108, the slide groove 105, the electric push rod 106 and the slider 107. Then the moving motor 109 will drive the grinding wheel 110 connected thereto to rotate. When the surface of the grinding wheel 110 contacts the surface of the screw shaft end of the ball screw, the main housing 201 and the auxiliary housing 202 are directly docked and installed. When the main housing 201 and the auxiliary housing 202 are docked and installed, the clamping rotating end of the clamping rotating assembly 103 and the grinding wheel 110 are just between the inside of the main housing 201 and the inside of the auxiliary housing 202, and then the upper limit blocks 204 are installed on the two connecting blocks 203. When the two clamping ends of each limit block 204 are completely docked with the inside of the corresponding set of limit grooves 205, the magnetic buckle 206 on the limit block 204 is just in contact with the magnetic buckle 206 on the corresponding limit groove 205. At this time, with the cooperation of the four sets of magnetic buckles 206, the limit block 204 can be prevented from automatically moving out of the corresponding connecting block 203. When the main shell 201 and the auxiliary shell 202 complete the fixing operation, the controller 111 and the clamping rotating assembly 103 are directly used to rotate the screw shaft end of the fixed ball screw. Then, the controller 111 and the motor 109 are used to rotate the grinding wheel 110. When the grinding wheel 110 rotates, the screw shaft end surface of the ball screw in contact with it can be ground. At this time, the dust generated when the screw shaft end of the ball screw is ground will be prevented from being scattered in the environment with the cooperation of the main shell 201 and the auxiliary shell 202.

[0027] Working principle: when it is necessary to grind the screw shaft end of the ball screw, first use the cooperation of the controller 111 and the clamping rotating assembly 103 to fix the screw shaft end of the ball screw, and then use the cooperation of the controller 111, the first rectangular block 104, the second rectangular block 108, the slide groove 105, the electric push rod 106 and the slider 107 to drive the motor 109 to move, and then the moving motor 109 will drive the grinding wheel 110 connected thereto to rotate, and when the surface of the grinding wheel 110 contacts the surface of the screw shaft end of the ball screw, the main shell 201 and the auxiliary shell 202 are directly docked and installed. When the main shell 201 and the auxiliary shell 202 are docked and installed, the clamping rotating end of the clamping rotating assembly 103 and the grinding wheel 110 are just between the inside of the main shell 201 and the inside of the auxiliary shell 202, and then the upper limit blocks 204 are installed on the two connecting blocks 203. When the two clamping ends of each limit block 204 are completely docked with the inside of the corresponding set of limit grooves 205, the magnetic buckle 206 on the limit block 204 is just in contact with the magnetic buckle 206 on the corresponding limit groove 205. At this time, with the cooperation of the four sets of magnetic buckles 206, the limit block 204 can be prevented from automatically moving out of the corresponding connecting block 203. When the main shell 201 and the auxiliary shell 202 complete the fixing operation, the controller 111 and the clamping rotating assembly 103 are directly used to rotate the screw shaft end of the fixed ball screw. Then, the controller 111 and the motor 109 are used to rotate the grinding wheel 110. When the grinding wheel 110 rotates, the screw shaft end surface of the ball screw in contact with it can be ground. At this time, the dust generated during the grinding of the screw shaft end of the ball screw will be prevented from being scattered in the environment with the cooperation of the main shell 201 and the auxiliary shell 202.
