DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the embodiments.

[0024] See also Figure 1-4 The utility model provides an auxiliary clamping device for a machining center, including a base plate 1 and a workbench 2. The workbench 2 is fixed to the top side wall of the base plate 1. Two symmetrically distributed brackets 3 are fixed to the top side wall of the workbench 2. A positioning component 4 is provided on one side of the two brackets 3. Two symmetrically distributed connecting plates 5 are commonly fixed to the adjacent side walls of the two brackets 3.

[0025] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it is worth specifically explaining that the positioning component 4 includes a mounting plate 41, which is fixed to a side wall of one side of the bracket 3, a servo motor 42 is fixed to the bottom side wall of the mounting plate 41, and a bidirectional screw 43 is rotatably connected to the inner side wall of the bracket 3, and two symmetrically distributed threaded sleeves 44 are threadedly connected to the external thread of the bidirectional screw 43; a transmission plate 45, which is slidably connected to the inner side of the bracket 3, and two symmetrically distributed hinged seats a46 are fixed to the top side wall of the transmission plate 45, and a hinged seat b47 is fixed to the bottom side wall of the thread sleeve 44, and a connecting rod 48 is hinged between the hinged seat a46 and the hinged seat b47. Through the setting of the positioning component 4, the workpiece can be clamped and positioned according to the workpiece clamping and positioning requirements, and the adaptability is wide, and it can be suitable for the clamping work requirements of workpieces of different sizes and specifications, and the clamping and positioning effect of the workpiece is better. Compared with traditional clamping devices, this device can greatly improve the clamping efficiency of the workpiece.

[0026] Further as Figure 1 and Figure 4 As shown, it is worth explaining in detail that a guide rod 6 is fixed to the top side wall of the wire sleeve 44, and two symmetrically distributed guide grooves 7 are provided on the side wall of one side of the bracket 3. The guide rod 6 is slidably connected to the inside of the guide groove 7. The setting of the guide rod 6 in the guide groove 7 plays a guiding and limiting role for the wire sleeve 44, thereby further improving the stability of the wire sleeve 44 during movement.

[0027] This solution has the following working process: when the workpiece needs to be positioned and pressed before processing, first place the workpiece on the top surface of the anti-slip pad 13 to ensure that the workpiece is directly below the rubber plate 9. The bidirectional screw 43 is driven by the servo motor 42 to rotate synchronously. The threaded transmission effect between the bidirectional screw 43 and the thread sleeve 44 is utilized, and the guide rod 6 is slidably set in the guide groove 7, so that the thread sleeve 44 is subjected to force and reciprocates left and right, driving the hinge seat b47 to move synchronously. The transmission effect of the connecting rod 48 is utilized to make the transmission plate 45 move after being subjected to force until the rubber plate 9 and the workpiece are in a fitted state. At this time, the damper 10 and the spring 11 are squeezed and compressed, so that the workpiece is in a relatively compressed state.

[0028] According to the above working process, it can be known that: through the setting of the positioning component 4, the workpiece can be clamped and positioned according to the clamping and positioning requirements of the workpiece, and it has a wide adaptability and can be suitable for the clamping work requirements of workpieces of different sizes and specifications, and the clamping and positioning effect of the workpiece is better. Compared with the traditional clamping device, the present device can greatly improve the clamping efficiency of the workpiece, and by adopting the setting of two positioning components 4, not only can the same workpiece be clamped and positioned at the same time, but also two workpieces can be clamped and positioned separately, thereby ensuring the clamping and positioning efficiency of the workpiece, simple operation, greatly improving the clamping and positioning effect of the workpiece, and effectively preventing the displacement of the workpiece when the workpiece is clamped and positioned.

[0029] Further as Figure 2 As shown, it is worth explaining in detail that two symmetrically distributed sliding sleeves 8 are fixed to the side wall of one side of the transmission plate 45, and the sliding sleeves 8 are slidably connected to the outer side of the bracket 3. Through the setting of the sliding sleeves 8, a guiding and limiting function is played on the transmission plate 45, which effectively improves the stability of the transmission plate 45 when moving.

[0030] Further as Figure 2 As shown, it is worth explaining in detail that a rubber plate 9 is arranged directly below the transmission plate 45, and a plurality of dampers 10 distributed equidistantly are fixed to the top side wall of the rubber plate 9, and the other end of the damper 10 is fixed to the bottom side wall of the transmission plate 45. A spring 11 is sleeved on the outer surface of the damper 10, and one end of the spring 11 is fixed to the top side wall of the rubber plate 9, and the other end of the spring 11 is fixed to the bottom side wall of the transmission plate 45. Through the arrangement of the damper 10 and the spring 11, a pre-tightening effect is played when the workpiece is pressed, thereby further improving the pressing effect on the workpiece, having a better pressing effect on the workpiece, and preventing the workpiece from being displaced when the workpiece is pressed and positioned.

[0031] Further as Figure 1 and Figure 4 As shown, it is worth explaining in detail that the opening length of the guide groove 7 is smaller than the thread length of the bidirectional screw rod 43, and a mounting groove 12 is opened on the top side wall of the workbench 2, and an anti-skid pad 13 is fixed inside the mounting groove 12. The anti-skid pad 13 is located directly below the two rubber plates 9. The setting of the anti-skid pad 13 can not only prevent slipping when placing the workpiece, but also avoid displacement of the workpiece during clamping. In addition, the setting of the guide groove 7 and the bidirectional screw rod 43 can prevent the thread sleeve 44 from moving too far and causing separation from the bidirectional screw rod 43.

[0032] In summary: through the setting of the guide rod 6 in the guide groove 7, it plays a guiding and limiting role on the thread sleeve 44, further improving the stability of the thread sleeve 44 when moving, and through the setting of the sliding sleeve 8, it plays a guiding and limiting role on the transmission plate 45, effectively improving the stability of the transmission plate 45 when moving, and through the setting of the damper 10 and the spring 11, it plays a pre-tightening role when the workpiece is pressed, thereby further improving the clamping effect on the workpiece, and the clamping effect on the workpiece is better, preventing the displacement of the workpiece when the workpiece is pressed and positioned, and through the setting of the anti-slip pad 13, it can not only play an anti-slip role when placing the workpiece, but also avoid the displacement of the workpiece during pressing, and through the setting of the guide groove 7 and the bidirectional screw rod 43, it can avoid the thread sleeve 44 moving too far and causing separation from the bidirectional screw rod 43.
