[0024] Example

[0025] Reference Figure 1-4 This embodiment of the invention provides a mobile workbench positioning mechanism, comprising:

[0026] The clamping assembly 100 includes a platform 101, a fixing block 102 fixedly connected to the top of the platform 101, a first lead screw 106 rotatably connected to the inner wall of the fixing block 102, a triangular handle 105 fixedly connected to the end of the first lead screw 106, a lead screw sleeve 107 threadedly connected to the working surface of the first lead screw 106, a second lead screw 110 rotatably connected to the inner wall of the lead screw sleeve 107, a connecting block 108 threadedly connected to the working surface of the second lead screw 110, and a clamp 109 fixedly connected to the end of the connecting block 108. The clamp 109 is slidably connected to the top of the platform 101, and the lead screw sleeve 107 is slidably connected to the top of the platform 101.

[0027] The stamping assembly 200 includes a fixed post 201 fixedly connected to the middle of the table 101, a stamping plate 202 rotatably connected to the side wall of the fixed post 201, a fixed plate 203 rotatably connected to the side wall of the fixed post 201, a stamping rod 204 slidably connected to the inner wall of the fixed plate 203, a fixed piece 205 fixedly connected to the side wall of the stamping rod 204, a spring 206 sleeved on the side wall of the stamping rod 204, a stamping head 213 fixedly connected to the bottom of the stamping rod 204, and a servo motor 207 fixedly connected to the top of the fixed post 201. The output end of the servo motor 207 is fixedly connected to a connector 212. The stamping plate 202 is rotatably connected to the top of the table 101, the spring 206 is elastically connected to the bottom of the fixed piece 205, and the spring 206 is elastically connected to the top of the fixed plate 203.

[0028] The clamping assembly 100 also includes an adjusting handle 111 fixedly connected to the end of the second lead screw 110, and the side wall of the adjusting handle 111 is provided with an anti-slip groove.

[0029] Specifically, the table 101 serves as a work surface, with two first lead screws 106 mounted on top. These screws rotate within the internal slots of a fixing block 102, which is fixed to the table 101. By rotating the triangular handle 105 at the end of the first lead screw 106, the lead screw sleeve 107 can be displaced on the working surface of the first lead screw 106. The second lead screw 110 rotates within the slot of the lead screw sleeve 107, with an adjusting handle 111 fixed at its end. A connecting block 108 is threaded onto the working surface of the second lead screw 110. When the adjusting handle 111 is rotated, causing the second lead screw 110 to rotate, the connecting block 108 causes the clamp 109 to shift, thus displacing the material plate. A fixing post 201, penetrating the table 101, is fixed to the side of the table 101. The stamping plate 202 is connected to the fixing post 201. Plate 203 can rotate around fixed post 201. Fixed plate 203 has two layers and a circular hole. The stamping rod 204 is set inside the hole and can perform up and down stamping movements. Fixed plate 205 is fixed to the surface of stamping rod 204. One end of spring 206 is connected to the bottom of fixed plate 205 and the other end is connected to the top of lower fixed plate 203 to support stamping rod 204. Servo motor 207 is installed on the top of fixed post 201. Connector 212 is fixed to the output end of servo motor 207. Connector 212 is adapted to the top of stamping rod 204. When servo motor 207 works, connector 212 pushes stamping rod 204 downward to press. When the work is finished, the elastic support of spring 206 makes stamping rod 204 return.

[0030] The clamping assembly 100 also includes a timing pulley 103 fixedly connected to the end of the first lead screw 106. The working surface of the timing pulley 103 is meshed with a timing belt 104. A gear of the same specification as the timing pulley 103 is fixedly connected at the connection between the triangular handle 105 and the first lead screw 106. The timing belt 104 is meshed with the gear.

[0031] Furthermore, the synchronous pulley 103 is fixed to the ends of the two first lead screws 106 and connected by the synchronous belt 104. One of the synchronous pulleys 103 is also connected to the side wall of the triangular handle 105. When the triangular handle 105 is rotated, the two first lead screws 106 rotate synchronously under the action of the synchronous belt 104.

[0032] The stamping assembly 200 also includes a stamping hole 208 opened in the center of the stamping plate 202, and a stamping head 213 fixedly connected to the bottom of the stamping rod 204. The stamping head 213 is slidably connected to the inner wall of the stamping hole 208.

[0033] The stamping assembly 200 also includes a worm gear 209 rotatably connected to the side wall of the table 101. The working surface of the worm gear 209 meshes with the rack on the side wall of the stamping plate 202. A rotating shaft is connected to the side wall of the worm gear 209. The rotating shaft is rotatably connected to a pipe opened in the inner wall of the table 101. A circular handle 210 is fixedly connected to its end.

[0034] The stamping assembly 200 also includes a scrap trough 211 formed at the bottom of the table 101, and the stamping head 213 is slidably connected to the center of the scrap trough 211.

[0035] Preferably, the circular handle 210 and the worm gear 209 are connected by a rotating shaft. The rotating shaft rotates in a pipe inside the table plate 101. When the circular handle 210 rotates, the worm gear 209 rotates. The working surface of the worm gear 209 meshes with the rack on the side of the stamping plate 202. Therefore, the fixed column 201 rotates with the worm gear 209 and rotates around the fixed column 201 as the axis. The stamping plate 202 has stamping holes 208 of different shapes. By rotating the stamping plate 202, different stamping holes 208 can be changed above the scrap trough 211 to achieve the purpose of stamping different shapes.

[0036] The bottom of the platform 101 is symmetrically provided with supporting square tubes 112, and the bottom of the supporting square tubes 112 is provided with rubber pads.

[0037] It should be noted that four supporting square tubes 112 are symmetrically arranged at the bottom of the platform 101. The bottom of the supporting square tubes 112 is equipped with rubber pads, which serve to prevent slipping and reduce shock.

[0038] In use, the operator rotates the circular handle 210, which drives the worm gear 209 to rotate via the rotating shaft. The worm gear 209 meshes with the rack on the side wall of the stamping plate 202, driving the stamping plate 202 to rotate around the fixed column 201 as the axis, so that the required stamping hole 208 is switched above the waste trough 211. After the operator fixes the material plate in the clamp 109, he rotates the triangular handle 105. Through the transmission action of the gear and the synchronous belt 104, the two first lead screws 106 rotate synchronously, driving the lead screw sleeves 107 on both sides to slide along the surface of the table plate 101, so that the material plate moves laterally under the clamping of the clamp 109. By rotating the adjusting handle 111, the second lead screw 110 rotates and drives the connecting block 108 to drive the clamp 109 to move longitudinally, so as to realize the fine position adjustment of the material plate in the clamping state. After adjusting to the appropriate position, the operator uses a switch to start the servo motor 207. The output connector 212 pushes the stamping rod 204 downward, which compresses the spring 206 and drives the stamping head 213 to move downward along the stamping hole 208, completing the stamping of the material plate. After stamping, the servo motor 207 drives the connector 212 to reset, and the elastic force of the spring 206 pushes the fixing plate 205 and the stamping rod 204 upward to reset, continuing to displace the material plate before waiting for the next stamping.

[0039] In summary, the stamping holes 208 can be quickly switched by rotating the stamping plate 202, enabling stamping of various shapes without the need to change the stamping head 213, making operation convenient. The setting of the first lead screw 106 and the second lead screw 110 can meet the precise positioning requirements of the material plate. The position can be quickly adjusted by simply rotating the corresponding handle, improving efficiency. The synchronous transmission of the two lead screws ensures balanced force on the fixture, achieving stable clamping of the material plate and effectively preventing stamping displacement. The bottom rubber pad support structure reduces operating vibration and noise, while the waste trough can directly collect processing waste, maintaining a clean working environment.
