[0002] Measuring instruments are third-party standards required to obtain certain attribute values ​​of the target object. Measuring instruments generally have units such as scales and volumes. At the same time, measuring instruments are generally equipped with different accessories for use. Most accessories are to assist measuring instruments to better complete measurement tasks and improve measurement accuracy, stability and convenience. Some common accessories include support frames, baffles, rulers, etc. Most accessories are small parts and are easy to lose during use. There are also disposable accessories, which lead to large consumption of accessories. Therefore, when processing accessories, it is necessary to consider the processing efficiency and how to perform processing steps such as drilling and grinding multiple small parts.

[0011] Through the above technical solution, the first motor assembly drives the support shaft to rotate through the engagement of the driving gear and the driven gear, and then drives the polygonal mounting sleeve to rotate through multiple cross support frames, and each rotation is 45 degrees. The polygonal mounting sleeve is rotated to drive multiple accessory clamping mechanisms to continuously cycle and complete the clamping of the workpiece.

[0012] Furthermore, the accessory clamping mechanism includes a rotating shaft rotatably connected to the fixed ear assembly and an L-shaped limit plate fixedly connected to the outer wall of the polygonal mounting sleeve, the two sides of the rotating shaft are respectively fixedly connected with a flat tooth plate and a limit gear, the outer wall of the rotating shaft is fixedly connected with a plurality of bidirectional spiral sleeves, both ends of the plurality of bidirectional spiral sleeves are spirally connected to two transmission clamping plates, and the plurality of transmission clamping plates are fixedly connected with rubber pads on the sides close to each other, the rear end of the polygonal mounting sleeve is fixedly connected to the mounting shell, the inner wall of the mounting shell is slidably connected to a limit tooth block, and the rear end of the limit tooth block is fixedly connected to a permanent magnet block.

Then the second motor assembly drives the square sleeve and the square rod to rotate, and then the driving block and the plane tooth plate are engaged to realize the rotation of the rotating shaft. At the same time, the second motor assemblies in the two clamping drive mechanisms rotate in different directions respectively, so as to realize the work of clamping and releasing the workpiece.

After the fallen workpiece is rotated 45 degrees, due to The workpiece to be processed is in an inclined state, so one end of the workpiece will be close to the L-shaped limit plate 402. At this time, under the drive of the corresponding clamping drive mechanism 8, the rotation of the rotating shaft 401 will be driven. When the rotating shaft 401 rotates, the multiple transmission clamping plates 406 that are limited will approach each other in pairs due to the effect of the spiral connection until the clamping of multiple workpieces is completed. At the same time, under the drive of the corresponding electromagnetic drive mechanism 5, the limiting tooth block 409 slides in the mounting shell 408 until it engages with the limiting gear 404, thereby realizing the rotation limit of the rotating shaft 401. The rotating shaft 401 and multiple bidirectional spiral sleeves 405 are an integrated structure, and the two transmission clamping plates 406 on a single bidirectional spiral sleeve 405 are a symmetrical structure, which ensures that the transmission clamping plates 406 with symmetrical structures will approach each other in the process of rotation of the rotating shaft 401 and multiple bidirectional spiral sleeves 405.

[0049] like Figures 1-12 As shown, both sides of the rear end of the rotation drive mechanism 3 are fixedly connected with an electromagnetic drive mechanism 5, and the electromagnetic drive mechanism 5 includes a square tube 501, and the top of the front end surface of the square tube 501 is fixedly connected with a fixing piece 502, and a first electric rod 503 is installed on the fixing piece 502.

After the pushing or resetting is completed, the power is cut off, thereby completing the limit work and releasing the limit. The top of the mounting base 2 is fixedly connected to the support platform 6 at the front end of the rotation drive mechanism 3.

[0050] like Figures 1-14As shown, a control component 7 is installed at the top center of the support platform 6, and the control component 7 is electrically connected to the power drive components in the transmission and collection mechanism 1, the rotation drive mechanism 3, the electromagnetic drive mechanism 5, the clamping drive mechanism 8, the punching mechanism 9 and the burr grinding mechanism 10 through wires, ensuring that the first transmission device 101, the second transmission device 102, the first motor assembly 308, the first electric rod 503, the electromagnet assembly 504, the driving cylinder 802, the second motor assembly 804 and the hydraulic rod 903 can be controlled respectively by the control component 7 to achieve mutual cooperation.

A return spring 806 is fixedly connected between one end of the square rod 807 and the inner wall of the square sleeve 805, and the other end of the square rod 807 is fixedly connected to a driving block 808. The driving cylinder 802 drives the motor mounting seat 803 to move, thereby causing the driving block 808 to move until it is stuck on the teeth on the plane gear plate 403. At the same time, the return spring 806 is squeezed during the movement, and the driving block 808 is pressed against the plane gear plate 403 through the rebound force, and then the second motor assembly 804 drives the square sleeve 805 and the square rod 807 to rotate, and then the driving block 808 and the plane gear plate 403 are engaged to drive the rotation of the rotating shaft 401. At the same time, the second motor assemblies 804 in the two clamping drive mechanisms 8 rotate in different directions respectively, thereby realizing the work of clamping and releasing the workpiece.

[0051] like Figures 1-16As shown, a punching mechanism 9 is installed on the other side of the top of the mounting base plate 2, and the punching mechanism 9 includes a mechanism base 901 fixedly connected to one side of the top of the mounting base plate 2, and the top of the mechanism base 901 is fixedly connected to a mounting base 902, and two hydraulic rods 903 are installed on one side of the top of the mounting base 902, and a sliding base 904 is fixedly connected between the output ends of the two hydraulic rods 903, and a plurality of stamping connectors 905 are fixedly connected to the top of the sliding base 904, and one side of the plurality of stamping connectors 905 is fixedly connected to a punching column head 906.

After the punching is completed, it is reset, and the punched fragments will fall on the top of the mounting base plate 2 and can be collected later. In actual work, the horizontal position and height of the stamping connector 905 can be changed to realize the positioning of the punching column head 906 and the workpiece surface at different positions, thereby ensuring that punching can be achieved at any position on the workpiece surface.

[0052] like Figures 1-17 As shown, a burr grinding mechanism 10 corresponding to the rotary drive mechanism 3 is installed inside the mounting base 2. The burr grinding mechanism 10 includes a second electric rod 1001 installed inside the mounting base 2. The output end of the second electric rod 1001 is fixedly connected to a supporting mobile base 1002. The tops of the front and rear ends of the supporting mobile base 1002 are both installed with lifting electric cylinders 1003. A sliding shaft seat 1004 is fixedly connected between the tops of the two lifting electric cylinders 1003. A fourth motor assembly 1005 is installed at the top front end of the sliding shaft seat 1004. The fourth motor assembly 1005 is installed at the front end of the sliding shaft seat 1004. The output end of 005 is fixedly connected to a grinding shaft assembly 1006, and the two lifting electric cylinders 1003 drive the sliding shaft seat 1004 to rise, so that the grinding disk in the grinding shaft assembly 1006 is close to the surface of the workpiece, and then the fourth motor assembly 1005 drives the grinding shaft assembly 1006 to rotate to grind and clean the workpiece. Before using the device, the position of the grinding shaft assembly 1006 can be adjusted by the second electric rod 1001 according to the position of the punching hole. At the same time, the sliding shaft seat 1004 that completely blocks the groove of the mounting base plate 2 can prevent stamping debris from falling into the groove.

[0053] The working principle of this embodiment is as follows: when in use, the workpieces to be processed are placed in a row on one side of the top of the second transmission device 102, and the second transmission device 102 is started to continuously transmit and move the workpieces. After the workpieces are moved to one end under the guidance of multiple guide plates 104, they slide onto the L-shaped limit plate 402 on the top of the rotary drive mechanism 3 through the guide inclined plate 105, and then the second transmission device 102 stops transmitting. At this time, the first motor assembly 308 drives the support shaft 303 to rotate through the engagement of the driving gear 309 and the driven gear 304, and then drives the polygonal mounting sleeve 306 to rotate through multiple cross support frames 305, and stops after rotating 45 degrees (such as Figure 15 ), at this time, since the workpiece to be processed is in an inclined state, one end of the workpiece will be close to the L-shaped limit plate 402. At this time, the driving cylinder 802 in the clamping drive mechanism 8 located at the workpiece position pushes the motor mounting seat 803 to move, thereby causing the driving block 808 to move until it is stuck on the teeth on the plane gear plate 403. At the same time, the return spring 806 will be squeezed during the movement, and the driving block 808 will be closely attached to the plane gear plate 403 through the rebound force. Then the second motor assembly 804 drives the square sleeve 805 and the square rod 807 to rotate, and then the driving block 808 and the plane gear plate 403 are engaged to drive the rotation shaft 401 to rotate. When 401 rotates, the multiple transmission clamping plates 406 that are limited will approach each other in pairs due to the effect of the spiral connection until the clamping of the multiple workpieces is completed. Then, the first electric rod 503 in the electromagnetic drive mechanism 5 located at the workpiece position is extended, and at the same time, the electromagnet assembly 504 is energized, so that the electromagnet assembly 504 and the permanent magnet block 410 are no longer magnetically identical, and then the repulsive force is generated to push the limiting tooth block 409 to slide in the mounting housing 408 until it is engaged with the limiting gear 404. After that, the electromagnet assembly 504 stops energizing, thereby achieving the rotation limit of the rotating shaft 401, avoiding the occurrence of unstable clamping during the punching process;

[0054] Then the clamping drive mechanism 8 and the electromagnetic drive mechanism 5 are reset, and the first motor assembly 308 drives the polygonal mounting plate 306 to continue to rotate 45 degrees and then stop. At this time, the two hydraulic rods 903 push the sliding base 904 and then drive multiple stamping connectors 905 and multiple corresponding punching column heads 906 to punch multiple workpieces. After the stamping is completed, it is reset. At the same time, during the stamping process, the second transmission device 102 continues to move a distance, and slides a row of workpieces into the accessory clamping mechanism 4 that rotates to the top of the rotating drive mechanism 3. Then the first motor assembly 308 drives the polygonal mounting plate 306 to continue to rotate 45 degrees and then stop. At this time, the workpiece that has just fallen is clamped in the same way as above, and then it is rotated 45 degrees again and then stops. The two lifting electric cylinders 1003 drive the sliding shaft seat 1004 to rise, so that the grinding disk in the grinding shaft assembly 1006 is close to the surface of the workpiece, and then the fourth motor assembly 1005 drives the grinding shaft assembly 1006 to rotate to grind and clean the workpiece. Before the device is used, the position of the grinding shaft assembly 1006 can be adjusted by the second electric rod 1001 according to the position of the punching. After the grinding of the workpiece at the bottom is completed, the grinding shaft assembly 1006 is reset. During this grinding, the top accessory clamping mechanism 4 continues to receive the workpiece, and the side accessory clamping mechanism 4 continues to punch;

[0055] Then the polygonal mounting sleeve 306 continues to rotate 45 degrees, clamping the workpiece that has just fallen as above, and then stops after rotating 45 degrees again. The polished workpiece rotates to the other side, and the electromagnetic drive mechanism 5 and the clamping drive mechanism 8 at this position work. First, the magnetism of the electromagnet assembly 504 is changed by the reverse current, so that it can generate suction to the permanent magnet block 410, and under the pull of the first electric rod 503, the limit tooth block 409 leaves the limit gear 404 to release the limit, and then similarly, by the stretching of the driving cylinder 802 and the reverse rotation of the second motor assembly 804, the rotating shaft 401 and the multiple bidirectional spiral sleeves 405 are rotated in the opposite direction to release the clamping of the multiple workpieces. The workpiece will fall on the first transmission device 101, and the punched workpiece will be transmitted through the continuously moving first transmission device 101. Finally, after two 45-degree rotations, the accessory clamping mechanism 4 that completes a cycle returns to the top of the rotating drive mechanism 3 to continue receiving the fallen workpiece, and the cycle continues.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
