[0028] The same rod mechanism includes a synchronous screw 301, and the synchronous screw 301 is rotatably connected to the inside of the mounting seat 101, wherein two control clamping blocks 104 are screwed on both sides of the synchronous screw 301 through threads;

[0029] The different-rod mechanism includes an active screw 302, a driven screw 303 and a synchronous rod 304. The active screw 302 and the driven screw 303 are both rotatably connected to the inside of the mounting seat 101, and the active screw 302 and the driven screw 303 are on the same straight line. The other two control clamps 104 are respectively screwed on the outside of the active screw 302 and the driven screw 303 through threads, and the synchronous rod 304 is rotatably connected to the inside of the mounting seat 101.

[0030] In the disclosed embodiment, two groups of transmission components 2 are provided, and the two groups of transmission components 2 are respectively arranged on the outside of the synchronous screw 301 and the active screw 302. The rod bodies of the synchronous screw 301 and the active screw 302 both transmit the transmission gear 201 of the external transmission component 2. During use, the limiting function of the two groups of transmission components 2 can also realize the reset operation of the four control clamps 104. When the four control clamps 104 are controlled to approach each other, the four control clamps 104 can be restored to the position of the minimum clamping distance, so that the four control clamps 104 can be subsequently moved in the opposite direction to restore to the position of the maximum clamping distance to complete the reset operation.

[0031] In the embodiment of the present disclosure, the outside of the synchronous screw 301 and the active screw 302 are both provided with a synchronous groove 3011, and the inside of the control disk 202 is provided with a synchronous block 2021, and the synchronous blocks 2021 of the two control disks 202 are respectively inserted into the inside of the synchronous groove 3011. In use, when the drive motor 103 rotates forward and reverse, the installation and removal operation of the workpiece can be realized, and when the drive motor 103 rotates forward, it can drive the transmission gear 201 to rotate synchronously, and the transmission gear 201 can simultaneously drive the transmission gears of the two sets of transmission components 2 when rotating. The driving gear 201 rotates. Due to the action of the transmission top spring 2022, the gear teeth of the limit gear ring 2023 mesh with each other, so that the transmission gear 201 can rotate synchronously due to the extrusion and friction relationship between the bevel edges of the gear teeth of the limit gear ring 2023. When the transmission gear 201 rotates, the synchronization block 2021 can drive the screw at the corresponding position to rotate through the synchronization groove 3011, that is, one group of transmission components 2 can drive the synchronous screw 301 to rotate, and the other group of transmission components 2 can drive the active screw 302 to rotate, and the synchronous When the screw rod 301 rotates, it can drive the two control clamps 104 installed on its rod body to move synchronously and approach each other through the rod body thread, so as to realize the clamping operation of the position of two edges of the workpiece. The two ends of the synchronization rod 304 are respectively transmitted to the active screw rod 302 and the driven screw 303 through the gear set. When the active screw 302 rotates, it can drive the synchronization rod 304 to rotate through the gear set. When the synchronization rod 304 rotates, it can drive the driven screw 303 to rotate through another set of gear sets, so that when the active screw 302 rotates, The movable screw 303 will also rotate synchronously, so that the control clamping block 104 installed on the active screw 302 and the driven screw 303 will also move synchronously and approach each other, thereby realizing the clamping and positioning operation of the other two edges of the workpiece. It is easy to use and has fast positioning. When it is necessary to release the clamping and positioning relationship of the workpiece, it can be achieved by simply reversing the drive motor 103. When the drive motor 103 reverses, the straight edges between the gear teeth of the limit gear ring 2023 are engaged with each other, thereby driving the screw of the positioning component 3 to reverse and realize the operation of loosening the workpiece.

[0032] In the embodiment of the present disclosure, a transmission top spring 2022 is provided on the side of the control disk 202, and the two ends of the transmission top spring 2022 are respectively against the side of the control disk 202 and the inside of the transmission gear 201, and the control disk 202 and the transmission gear 201 are provided with a limiting tooth ring 2023 on the opposite sides. Under the action of the transmission top spring 2022, the gear teeth of the limiting tooth ring 2023 are pressed against each other, and the cross-sectional shape of a single gear tooth of the limiting tooth ring 2023 is a right triangle. In use, the transmission component 2 has a limiting function, so that the device can adapt to the clamping operation of special-shaped workpieces such as rectangles. Taking the same rod mechanism clamping the long side of a rectangular workpiece as an example, at this time, the two control clamping blocks 1 on the synchronous screw 301 04 will conflict with the long side edge of the rectangular workpiece, causing the clamping resistance to increase infinitely, and the clamping component can overcome the force of the transmission top spring 2022 to maintain the squeezing and friction relationship between the bevel edges of the gear teeth of the limiting tooth ring 2023 of this group of transmission components 2, so that only the transmission gear 201 of this group of transmission components 2 will idle thereafter, and the device will not be stuck, and the other group of transmission components 2 can still realize the transmission of the different-rod mechanism until the two control clamps 104 of the different-rod mechanism clamp and position the short side edge of the rectangular workpiece, and then the group of transmission components 2 will trigger the limit function. When the two groups of transmission components 2 have the trigger limit function, the clamping and positioning of the rectangular workpiece is completed, which is convenient for subsequent milling processing operations and stable to use.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In the utility model, after the workpiece is installed and positioned on the top of the mounting seat 101, the milling operation on the workpiece can be started. After the processing is completed, the workpiece can be removed. When the driving motor 103 rotates forward and backward, the installation and removal operation of the workpiece can be realized. When the driving motor 103 rotates forward, it can drive the transmission gear 201 to rotate synchronously. When the transmission gear 201 rotates, it can simultaneously drive the transmission gears 201 of the two groups of transmission components 2 to rotate. Because the teeth of the limiting gear ring 2023 are engaged with each other under the action of the transmission top spring 2022, the transmission gear 201 can rotate synchronously under the extrusion and friction relationship between the bevel edges of the teeth of the limiting gear ring 2023 when rotating. When the transmission gear 201 rotates, the synchronization block 2021 can The screw at the corresponding position is driven to rotate through the synchronous groove 3011, that is, one group of transmission components 2 can drive the synchronous screw 301 to rotate, and the other group of transmission components 2 can drive the active screw 302 to rotate. When the synchronous screw 301 rotates, it can drive the two control clamps 104 installed on its rod body to move synchronously and approach each other through the rod body thread, so as to achieve the clamping operation of the position of two edges of the workpiece. When the active screw 302 rotates, it can drive the synchronous rod 304 to rotate through the gear set. When the synchronous rod 304 rotates, it can drive the driven screw 303 to rotate through another group of gear sets, so that when the active screw 302 rotates, the driven screw 303 will also rotate synchronously, so that the control clamps 104 installed on the active screw 302 and the driven screw 303 4 will also move synchronously and approach each other, thereby realizing the clamping and positioning operation of the other two edges of the workpiece. When the clamping and positioning relationship of the workpiece needs to be released, it can be realized by reversing the driving motor 103. When the driving motor 103 reverses, the straight edges between the gear teeth of the limiting tooth ring 2023 are engaged with each other, thereby driving the screw of the positioning component 3 to reverse and realize the operation of loosening the workpiece. The transmission component 2 has a limiting function, so that the device can adapt to the clamping operation of special-shaped workpieces such as rectangles. Taking the same-rod mechanism clamping the long side of a rectangular workpiece as an example, at this time, the two control clamping blocks 104 on the synchronous screw 301 will resist the long side edge of the rectangular workpiece, so that the clamping resistance is infinitely increased, and the clamping component can overcome the transmission top spring 2022 to maintain the group of transmission components 2, the extrusion and friction relationship between the bevel edges of the gear teeth of the limiting tooth ring 2023 is increased, so that only the transmission gear 201 of this group of transmission components 2 will idle thereafter, and the device will not be stuck, while the other group of transmission components 2 can still realize the transmission of the different-rod mechanism until the two control clamps 104 of the different-rod mechanism clamp and position the short side edges of the rectangular workpiece, and then the group of transmission components 2 will trigger the limit function. After the two groups of transmission components 2 have the trigger limit function, the clamping and positioning of the rectangular workpiece is completed, which is convenient for subsequent milling operations. The limit function of the two groups of transmission components 2 can also realize the reset operation of the four control clamps 104. When the four control clamps 104 are controlled to be close to each other, the four control clamps 104 can be restored to the position of the minimum clamping spacing.Therefore, the four control clamps 104 can be moved in the reverse direction to restore to the maximum clamping distance position to complete the reset operation.
