[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0034] Please see Figures 1-6This utility model provides a technical solution: a grinding machine, including: a base 1, a first outer shell 2 connected and installed on the upper end of the base 1, the first outer shell 2 providing installation space for components such as grinding wheels 8, and a second outer shell 3 connected and installed on the upper end of the first outer shell 2, the second outer shell 3 providing installation space for components such as movable seats 62, and a fixed part of a lifting device 64 extending into the second outer shell 3 and electrically connected to a controller 5 is installed on the bottom end inside the first outer shell 2, the lifting device 64 drives the movable seats 62 to move up and down, the lifting device 64 can be an electric push rod, and the controller 5 located at the right end of the second outer shell 3 is installed on the upper end of the first outer shell 2, the controller 5 controlling the opening and closing of electronic equipment such as the lifting device 64;
[0035] A movable seat 62 extending from the front side of the second housing 3 is installed on the upper end of the movable part of the elevator 64. The movable seat 62 provides a mounting carrier for the second driver 6. Two guide rods 63 extending into the second housing 3 on the front and rear sides of the elevator 64 are symmetrically installed on the bottom inside the first housing 2. Both guide rods 63 that are slidably connected to the movable seat 62 pass through the movable seat 62. The two guide rods 63 work together to guide the movement of the movable seat 62. The fixed part of the second driver 6, which is electrically connected to the controller 5 and is located inside the outer cover 4, is set on the front end of the movable seat 62. The second driver 6 drives the annular baffle 61 to move up and down. The second driver 6 can be a motor.
[0036] An annular baffle 61 is installed on the lower end of the output shaft of the second driver 6. The annular baffle 61 provides a mounting carrier for the mounting post 77 and blocks the flying debris generated during grinding. The mounting post 77, whose other end is detachably connected to the middle of the lower end of the annular baffle 61 and extends into the annular baffle 61, is set on the middle of the upper end of the clamping plate 7. The clamping plate 7 and the annular baffle 61 are detachably connected through the mounting post 77. Multiple clamping grooves 71 are formed by recessing the upper surface of the clamping plate 7, which is located directly above the annular cylinder 21, and are located outside the mounting post 77. The cross-section of the clamping grooves 71 is gourd-shaped. The clamping grooves 71 provide clamping space for the workpiece.
[0037] Multiple threaded holes 73 are formed in the recessed outer end face of the clamping disk 7, which are respectively connected to multiple clamping slots 71. The threaded holes 73 provide installation space for clamping bolts. Multiple screws 74 are equidistantly threaded onto the upper end of the clamping disk 7. The screws 74 facilitate the easy assembly and disassembly of the cylinders 76 and the clamping disk 7. Multiple cylinders 76, which are alternately arranged with multiple clamping slots 71, are rotatably connected to the upper ends of multiple screws 74. The cylinders 76 provide a mounting carrier for components such as the level 72. Multiple levels 72, which are located above multiple clamping slots 71, are rotatably connected to the upper ends of multiple cylinders 76. The level 72 is used to calibrate the clamped workpiece.
[0038] Multiple round rods 75 located outside the screw 74 and slidably connected to the upper end of the clamping plate 7 are respectively set on the lower end of multiple cylinders 76. The round rods 75 restrict the installation of the cylinders 76. Multiple fastening bolts located on the lower side of the annular baffle 61 and with the rod part passing through the level 72 are respectively threaded to the upper end of the multiple levels 72. The fastening bolts can both rotate the level 72 and tighten the level 72.
[0039] The upper end of the coupling 81, which extends into the base 1 and is rotatably connected to the first housing 2, is detachably connected to the middle of the lower end of the grinding wheel 8 located in the first housing 2. The grinding wheel 8 is used to grind the workpiece. An auxiliary pulley 82 located in the base 1 is installed on the lower end of the coupling 81. The coupling 81 is driven to rotate through the auxiliary pulley 82. The fixing part of the first driver 11, which is electrically connected to the controller 5, is installed on the inner wall of the base 1. The rotating pulley 12 is driven to rotate through the first driver 11. The first driver 11 can be a motor.
[0040] The rotating pulley 12, which is connected to the auxiliary pulley 82 via a belt, is connected to the output shaft of the first driver 11. The rotating pulley 12 works in conjunction with the belt to rotate the auxiliary pulley 82. The annular cylinder 21, located directly below the clamping disc 7 and above the grinding wheel 8, is connected to the upper end of the first housing 2. The annular cylinder 21 blocks the splashes generated during grinding. The outer cover 4, which is located above the first housing 2 and can be automatically raised and lowered, is slidably connected to the front end of the second housing 3. The outer cover 4 is used to protect the operation.
[0041] In use, first insert the workpiece to be ground into the clamping groove 71, and make the end face of the workpiece to be ground fit against the level 72. Then, connect the clamping bolt to the corresponding threaded hole 73, and make the shank of the clamping bolt contact the outer end of the workpiece to be ground, thereby restricting the installation between the workpiece to be ground and the clamping groove 71. Then, use the fastening bolt to make the level 72 move along the end face of the workpiece to be ground, thereby correcting the workpiece to be ground. Then, rotate the clamping bolt again to secure the workpiece to be ground.
[0042] Then, the fastening bolt is rotated, so that the fastening bolt makes a squeezing contact with the end face of the workpiece to be ground, thereby restricting the installation of the level 72, effectively reducing the probability of the level 72 wobbling during grinding. In the same way as above, multiple workpieces to be ground are fastened to multiple clamping slots 71 respectively, so that the clamped workpieces are corrected, effectively reducing the probability of the workpiece tilting during clamping, effectively reducing the probability of over-grinding due to tilting and other factors, and effectively ensuring the grinding effect and quality.
[0043] Then, the mounting column 77 and the annular baffle 61 are fastened together. Then, the outer cover 4 is closed. Then, the first driver 11 and the second driver 6 are started by the controller 5. The tooling of the first driver 11 drives the rotating pulley 12 to rotate. With the assistance of the belt, the auxiliary pulley 82 rotates, which in turn causes the coupling 81 to rotate, thereby causing the grinding wheel 8 to rotate. The tooling of the second driver 6 drives the annular baffle 61 to rotate, thereby causing the mounting column 77, the clamping plate 7 and other components to rotate, which in turn causes the multiple clamped workpieces to be ground to rotate. Then, the lifting device 64 is started by the controller 5, thereby driving the movable seat 62 and the second driver 6 to move down, so that the annular baffle 61 and other components enter the annular cylinder 21 and the workpieces to be ground come into contact with the grinding wheel 8. The rotating grinding wheel 8 grinds the workpieces to be ground.
[0044] At this time, the grinding position is located in the cavity formed by the annular baffle 61 and the annular cylinder 21, realizing hidden grinding of the workpiece. This effectively reduces the probability of waste chips and other materials generated by grinding splashing randomly inside the outer cover 4, and effectively reduces the probability of electronic equipment such as the second driver 6 malfunctioning due to splashing, thus effectively ensuring the grinding effect and quality.
[0045] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
