[0034] In the industrial production and processing scene, the operator will start the air cylinder 3, the air cylinder 3 starts to work after receiving the start signal, the piston rod drives the adjusting plate 4 to move upward, and the abutting rod 5 installed on the side of the adjusting plate 4 also moves upward, the abutting rod 5 stably slides in the abutting sliding groove 7, and the abutting rod 5 moves in the abutting sliding groove 7, which converts linear motion into pushing force, so as to drive the driving plate 9 to rotate around the outer side of the sliding frame 10, and the linkage sliding groove 8 provided on the lower side of the driving plate 9 can abut against the linkage rod 6 during the rotation of the driving plate 9, the linkage rod 6 generates corresponding displacement under the abutting action of the linkage sliding groove 8, at this time, the sliding block 12 stably slides along the track on the sliding frame 10 to the middle position under the action of the linkage rod 6, so that the clamping block 11 gradually approaches, and the preliminary clamping and positioning of the workpiece is realized, the operator can accurately adjust the position of the clamping block 11 according to the specific requirements of different size workpieces, so that the clamping mechanism can easily adapt to workpieces of various sizes, greatly improving the versatility and practicality of the clamping mechanism.

[0035] Embodiment two: in order to improve the clamping effect of the clamping block 11 on the workpiece, an auxiliary mechanism is arranged, which improves the friction force on the workpiece through the contact action of the equipment and the workpiece, and ensures the clamping stability, such as Figure 3 、 Figure 4 and Figure 6The technical scheme is shown, and the application provides the following technical scheme: a anti-falling connecting rod clamping mechanism discloses that the inner side of the clamping block 11 is provided with an auxiliary mechanism, the auxiliary mechanism adjusts the clamping friction force through the contact deformation of the deformation plate 15 contained therein and the workpiece, the auxiliary mechanism comprises a flexible rubber block 16, the flexible rubber block 16 is fixedly connected to the inner side of the clamping block 11, the inner side of the clamping block 11 is provided in an inwardly inclined structure, the inner side of the clamping block 11 is fixedly connected with the deformation plate 15, the deformation plate 15 is provided with a hole, the outer side of the flexible rubber block 16 is provided with a rubber protrusion 17, the outer side of the flexible rubber block 16 is in contact with the deformation plate 15, and the rubber protrusion 17 corresponds to the position of the hole in the deformation plate 15, the deformation plate 15 is deformed through the resistance of the workpiece, and is in close contact with the outer wall of the workpiece, and the flexible rubber block 16 is deformed through the resistance of the deformation plate 15, so that the volume of the rubber protrusion 17 is increased.

[0036] In the process that the clamping mechanism clamps the workpiece, the deformation plate 15 arranged in the inner side of the clamping block 11 will first contact the surface of the workpiece, when the deformation plate 15 touches the workpiece, the resistance force generated by the workpiece will cause the deformation plate 15 to deform to a certain extent, so that the deformation plate 15 can be closely attached to the outer wall of the workpiece, and the contact area between the deformation plate 15 and the workpiece is increased, compared with the traditional rigid clamping mode, the large-area contact can more evenly distribute the clamping force, avoiding damage to the workpiece due to local stress concentration, at the same time, the deformation plate 15 will produce extrusion on the flexible rubber block 16 closely connected behind it during deformation, the flexible rubber block 16 has good elasticity and deformation ability, and after being extruded by the deformation plate 15, it will deform correspondingly, so that the volume of the rubber protrusion 17 originally uniformly distributed on the surface of the flexible rubber block 16 gradually increases, further increasing the friction between the workpiece and the rubber protrusion 17, effectively preventing the workpiece from slipping or falling during clamping, providing a solid foundation for subsequent processing operation, ensuring the precision and quality during processing, reducing processing errors and scrap rate caused by workpiece slipping or falling, thereby improving the efficiency and benefit of the whole production process.

[0037] Embodiment three: further ensure the stability of clamping, avoid slipping during clamping, set an adsorption mechanism, adsorb the upper part of the workpiece through the adsorption mechanism, thereby further improve the stability of clamping the workpiece, such as Figures 7-9The technical scheme is shown, the present application provides the following technical scheme: a kind of anti-drop connecting rod clamping mechanism, it is disclosed, the upper of fixed frame 1 is fixedly connected with the cylinder 3 of driving clamping mechanism to carry out operation, and the output end of cylinder 3 is fixedly connected with adjusting plate 4, the lower surface of adjusting plate 4 is provided with suction mechanism, suction mechanism is realized to the suction of workpiece after dust removal by the position change of air supply plate 25 and air supply box 23 contained therein, suction mechanism includes connecting rod 18, connecting rod 18 is fixedly connected on the lower surface of adjusting plate 4, and the lower end of connecting rod 18 is fixedly connected with suction plate 14, and the upper surface of suction plate 14 and the lower surface of adjusting plate 4 are fixedly connected with connecting plate 19, while the middle part of connecting plate 19 is provided with tooth block, fixed plate 2 is rotatably connected with bidirectional screw rod 20, and the outside of bidirectional screw rod 20 is fixedly connected with gear 22, when connecting plate 19 is moved upwards, the position of gear 22 and connecting plate 19 is corresponding, the tooth block of connecting plate 19 and gear 22 are mutually engaged, the outside of bidirectional screw rod 20 is threadedly connected with internal thread block 21, and the lower of internal thread block 21 is hingedly provided with rotating rod 24, suction plate 14 is fixedly connected with suction disc 13 inside, and the upper end of suction disc 13 is connected with air supply box 23, air supply box 23 is slidably connected with air supply plate 25 inside, the outside of air supply box 23 is fixedly connected with limiting plate 26, and the upper surface of limiting plate 26 and the lower end of rotating rod 24 are hingedly connected, when suction plate 14 is initially moved upwards, air supply plate 25 extrudes the gas inside air supply box 23, when suction plate 14 is moved upwards to the state that the tooth block of connecting plate 19 and gear 22 are mutually engaged, air supply plate 25 moves upwards along the inside of air supply box 23.

[0038] In the process of carrying out the clamping operation, the adjusting plate 4 continues to move upward under the continuous driving of the air cylinder 3, and the adjusting plate 4 is closely connected with the adsorption plate 14 through the connecting rod 18, so as to synchronously drive the adsorption plate 14 to move upward together. When the adsorption plate 14 initially moves upward, the gas supply box 23 will move upward synchronously, and at this time, the position of the gas supply plate 25 remains relatively stable and unchanged. In the process of upward movement of the gas supply box 23, due to the relative movement between the gas supply plate 25 and the internal space of the gas supply box 23, the gas supply plate 25 exerts a squeezing action on the gas in the internal space of the gas supply box 23. The squeezed gas is rapidly sprayed out from the adsorption disc 13 arranged in the internal space of the gas supply box 23, and acts on the workpiece surface to rapidly blow off a large amount of dust attached to the workpiece surface, effectively avoids the interference of dust with the adsorption effect in the subsequent adsorption process, and lays a solid foundation for the stable and reliable adsorption between the adsorption plate 14 and the workpiece in the subsequent process. With the continuous upward movement of the adsorption plate 14, the tooth block on the connecting plate 19 and the gear 22 enter the state of mutual engagement, the gear 22 starts to rotate under the meshing action of the tooth block, and the rotating power is transmitted to the bidirectional threaded rod 20 connected therewith. The bidirectional threaded rod 20 starts to rotate under the driving of the gear 22. Due to the special bidirectional threaded design, the internal threaded block 21 arranged on the outer side of the bidirectional threaded rod 20 moves to both sides with the rotation of the thread. The internal threaded block 21 is connected with the limiting plate 26 through the rotating rod 24. In the process of moving to both sides of the internal threaded block 21, the rotating rod 24 will be correspondingly rotated and displaced, thereby driving the limiting plate 26 to move. The movement of the limiting plate 26 promotes the upward movement of the gas supply plate 25 along the internal space of the gas supply box 23. The movement of the gas supply plate 25 changes the gas pressure distribution in the internal space of the gas supply box 23, so that the gas pressure difference between the gas supply box 23 and the adsorption disc 13 increases, thereby generating adsorption force at the adsorption disc 13 to tightly adsorb the workpiece on the adsorption plate 14, realizing the stable clamping of the workpiece, reducing the displacement or shaking of the workpiece in the clamping process due to various external forces, thereby ensuring the stability and precision of the workpiece clamping movement, and better meeting the strict requirements of industrial production on workpiece clamping.

[0039] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
