DETAILED DESCRIPTION
[0024] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0025] See also Figure 1-4 A pneumatic drilling and tapping device for a motor cover includes a conveying mechanism 1, which includes a support frame 101. A first stepper motor 102 is fixedly connected to the bottom of the support frame 101. A rotating disk 103 is fixedly connected to the output end of the first stepper motor 102. The first stepper motor 102 can drive the rotating disk 103 to rotate when starting. The bottom of the rotating disk 103 is fixedly connected to a plurality of support columns 104 in an annular array. The bottom of each group of support columns 104 is movably connected to a first ball 105. Each group of first ball 105 is in contact with the top of the support frame 101. The arrangement of the support columns 104 and the first ball 105 can play an auxiliary supporting role for the rotating disk 103. During the rotation of the rotating disk 103, the support columns 104 and the first ball 105 rotate accordingly, so that the first ball 105 can roll on the top of the support frame 101.
[0026] The limiting mechanism 2 includes a fixing plate 204 fixedly connected to the bottom of the rotating disk 103 in an annular array, and each group of fixing plates 204 is symmetrically fixedly connected to a side of the guide disk 211, and each group of fixing plates 213 is fixedly connected to the rotating disk 103. The setting of the fixing plates 213 can further connect and fix the fixing plates 204 to the rotating disk 103, thereby improving the stability of the fixing plates 204. The interior of each group of fixing plates 204 is slidably connected to a sliding rod 210, and the setting of the fixing plates 204 can guide the sliding of the sliding rod 210. A guide plate 211 is fixedly connected to the top of the support frame 101, and the output end of the first stepper motor 102 passes through the guide plate 211. The outer side of each group of sliding rods 210 is fixedly connected to a limit ring 206, and a spring 207 is fixedly connected between the limit ring 206 and the fixed plate 204. The specific spring 207 is in a compressed state, so that the elastic action of the limit ring 206 can push the sliding rod 210 to move to one side of the guide plate 211.
[0027] The side of each group of sliding rods 210 close to the guide plate 211 is movably connected with a second ball 205, and each group of second ball 205 is in contact with the outer wall of the guide plate 211. The setting of the second ball 205 can reduce the wear between the sliding rod 210 and the guide plate 211, so that the second ball 205 can roll along the outer wall of the guide plate 211 when the sliding rod 210 rotates with the rotating plate 103. A groove 212 is provided on one side of the outer wall of the guide plate 211. When the second ball 205 rolls to the inside of the guide plate 211, the spring 207 recovers its deformation, thereby adjusting the position of the sliding rod 210. A plurality of fixed clamping blocks 202 are fixedly connected to the top of the rotating plate 103 in an annular array. The setting of the fixed clamping blocks 202 can limit the inner side of the motor cover.

Each group of sliding blocks 208 is slidably connected to the rotating disk 103, and the top of each group of sliding blocks 208 is fixedly connected to a movable clamping block 203. The setting of the movable clamping block 203 can synchronously move the sliding rod 210 and the sliding block 208, thereby limiting the other side of the interior of the motor cover, so that the movable clamping block 203 and the fixed clamping block 202 can limit and fix the motor cover to be drilled. The bottom of each group of sliding blocks 208 is threadedly connected with a limiting bolt 209, and each group of limiting bolts 209 is respectively abutted against each group of sliding rods 210. The setting of the limiting bolts 209 can limit the sliding blocks 208, and at the same time, the limiting of the sliding blocks 208 can be released when loosened, so as to facilitate the adjustment of the position of the sliding blocks 208, and then facilitate the adjustment of the distance between the moving clamping block 203 and the fixed clamping block 202, so as to meet the requirements of limiting and fixing motor covers with different inner diameters, thereby effectively improving the applicability of the entire device.
[0029] The drilling and tapping mechanism 3 includes two groups of C-shaped frames 301 symmetrically fixedly connected to one side of the support frame 101. The top wall of the C-shaped frame 301 is fixedly connected with a crossbeam 302, and the bottom of the crossbeam 302 is symmetrically fixedly connected with a column 303. The arrangement of the crossbeam 302 and the column 303 can further support and fix the C-shaped frame 301, thereby improving the stability of the C-shaped frame 301. The top of the two groups of C-shaped frames 301 is provided with a slide groove 304, and the inside of the two groups of slide grooves 304 is provided with a screw rod 305 rotatably connected to the C-shaped frame 301. The outer side of the two groups of screw rods 305 is threadedly connected with a sliding seat 306. When the screw rod 305 rotates, it can drive the sliding seat 306 to slide, thereby adjusting the position of the sliding seat 306. One side of the two sets of C-shaped frames 301 is fixedly connected with a second stepper motor 310, and the output ends of the two sets of second stepper motors 310 are respectively fixedly connected with the two sets of screw rods 305. The second stepper motor 310 is set to drive the screw rods 305 to rotate when starting. The sliding seat 306 is slidably connected to the C-shaped frame 301, and the bottom of the two sets of sliding seats 306 is fixedly connected with a hydraulic rod 307. The output end of the hydraulic rod 307 on one side is fixedly connected with a tapping machine 308, and the output end of the hydraulic rod 307 on the other side is fixedly connected with a pneumatic drill 309. The two sets of hydraulic rods 307 can respectively drive the tapping machine 308 and the tapping machine 308 to move up and down when starting.
[0030] In this embodiment, the tapping machine 308 and the pneumatic drill 309 are prior art and will not be described in detail herein.
[0031] When in use, the motor cover to be drilled and tapped is placed on the top of the rotating disk 103, and the corresponding movable clamping block 203 and the fixed clamping block 202 are both located inside the motor cover to be drilled and tapped, and then the first stepper motor 102 is started, so that the first stepper motor 102 can drive the rotating disk 103 and each group of sliding rods 210 to rotate when starting work, and at the same time, the second ball 205 on the sliding rod 210 rolls along the outer wall of the guide plate 211. When the corresponding second ball 205 rolls away from the inside of the groove 212, the corresponding sliding rod 210 and the corresponding sliding block 208 can be pushed to move to the side away from the guide plate 211, and the corresponding movable clamping block 203 moves to the side away from the corresponding fixed clamping block 202. When the corresponding second ball 205 completely rolls away from the inside of the groove 212, the corresponding fixed clamping block 202 and the movable clamping block 203 are pressed against the inner wall of the motor cover to be drilled and tapped, thereby realizing the limit fixation of the motor cover;
[0032] When the position of the motor cover to be drilled is transported to the bottom of the pneumatic drill 309, the pneumatic drill 309 and the corresponding hydraulic rod 307 are started, so that the corresponding hydraulic rod 307 can drive the pneumatic drill 309 to move downward, so that the pneumatic drill 309 that has started working can perform drilling operations on the motor. After the drilling is completed, the corresponding hydraulic rod 307 is started to drive the pneumatic drill 309 upward, and then the first stepper motor 102 is started again, so that the first stepper motor 102 drives the motor cover that has been drilled to the bottom of the tapping machine 308, and then the tapping machine 308 and the hydraulic rod 307 corresponding to the tapping machine 308 are started, so that the hydraulic rod 307 corresponding to the tapping machine 308 drives the tapping machine 308 downward, so that the tapping machine 308 that has started working can perform tapping operations on the hole drilled by the pneumatic drill 309;
[0033] During the drilling and tapping process of the previous group of motor covers, the subsequent motor covers to be drilled and tapped can be placed on the top of the remaining adjacent fixed clamping blocks 202 and movable clamping blocks 203, so that after the drilling of the previous group of motor covers is completed, the next group of motor covers can be transported to the inside of the pneumatic drilling machine 309 for drilling. At the same time, after the tapping of the previous group of motor covers is completed, the next group of motor covers to be tapped can be transported to the bottom of the tapping machine 308 for tapping, so that there is no need to wait for the drilling and tapping of the previous group of motor covers to be completed before removing the motor covers that have been drilled and tapped, and then clamping the next group of motor covers to be drilled and tapped, which effectively reduces the waiting time. Waiting time improves the efficiency of drilling and tapping the motor cover. After the corresponding positions of the motor cover placed on the top of the rotating disk 103 are drilled and tapped, the two groups of second stepper motors 310 can be started, so that the two groups of second stepper motors 310 respectively drive the two groups of screw rods 305 to rotate, thereby driving the two groups of sliding seats 306 to move, and then driving the positions of the tapping machine 308 and the pneumatic drill 309 to adjust the positions of the pneumatic drill 309 drilling and the tapping machine 308 tapping, so as to facilitate the adjustment of the drilling and tapping positions of the motor cover, thereby meeting the drilling and tapping requirements of different positions of the motor cover.

They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
