Technical Field

[0001] The utility model relates to the technical field of jacking mechanisms, in particular to a side-pushing jacking mechanism. Background Art

[0002] At present, in the process of mechanical production and manufacturing, jacking mechanisms are widely used, and most jacking mechanisms realize the jacking action by setting up multiple jacking drive parts.

[0003] In an existing lifting mechanism, the lifting mechanism is powered by a cylinder, a hydraulic cylinder, a motor-driven screw rod, or a motor-driven gear rack, and the workpiece is moved up and down through a guide mechanism.

[0004] With the continuous development of modern production, the development of lifting mechanisms is also changing with each passing day. When the traditional press is riveted, the bottom workpiece is fixed and cannot achieve assembly line automatic production. When pressing products now, the products are generally placed on the carrier, and the carrier needs to be moved to the top of the lifting mechanism through the assembly line. The lifting cylinder drives the carrier to lift up and position it. After that, the pressing cylinder drives the pressure head to descend and press the product on the carrier. At this time, a lifting and pressing mechanism is needed to complete the above operation.

[0005] However, the existing jacking mechanisms mostly adopt the direct push method of cylinders. If they are used as support under turntable riveting equipment, it is necessary to select a cylinder with a larger cylinder diameter as the power output, the volume will also be relatively large, and the overall cost will increase accordingly. Utility Model Content

[0009] In one embodiment of the utility model, a support block is connected to the upper end surface of the sliding guide assembly, and the support block is used to contact the stressed workpiece.

[0010] In one embodiment of the utility model, a linear guide rail is provided on the mounting base plate, and the linear guide rail is arranged along the extension and retraction direction of the piston rod of the side thrust cylinder. A linear slider is connected to the lower slider, and the linear slider is arranged on the linear guide rail, and the linear slider can slide along the linear guide rail.

[0011] In one embodiment of the utility model, the sliding guide assembly includes a sliding plate, a guide column and a linear bearing, the linear bearing is fixedly arranged on the sliding plate, the lower end of the guide column is fixedly arranged on the mounting base plate, the guide column passes through the linear bearing, and the guide column and the linear bearing are slidably connected, the upper slider is connected to the lower end surface of the sliding plate, and the support block is arranged on the upper end surface of the sliding plate.

[0015] In one embodiment of the present invention, the number of the guide pillars is two, the number of the linear bearings is two, and the guide pillars and the linear bearings are arranged in a one-to-one correspondence.

[0016] In one embodiment of the utility model, a floating joint is connected to the piston rod of the side thrust cylinder, and the side thrust cylinder is connected to the lower slider via the floating joint.

[0017] The above technical solution of the utility model has the following beneficial effects compared with the prior art:

When the piston rod of the side thrust cylinder 2 is extended or retracted, it can drive the lower slider 3 to move in a straight line, and the upper slider 5 will not change its position in the moving direction of the lower slider 3, so that the contact surface between the upper slider 5 and the lower slider 3 moves relative to each other, that is, the inclined surface 1 31 and the inclined surface 2 51 move relative to each other, thereby adjusting the upper slider 5 to move in the vertical direction, that is, realizing the lifting action of the upper slider 5.

[0027] In the above structure, the installation base plate 1 is provided with a linear guide rail 11, and the linear guide rail 11 is arranged along the extension direction of the piston rod of the side thrust cylinder 2. The lower slider 3 is connected with a linear slider 33, and the linear slider 33 is arranged on the linear guide rail 11, and the linear slider 33 can slide along the linear guide rail 11.

[0029] In the above structure, the sliding guide assembly 4 further includes a guide post fixing block 44 and a spring 45. The guide post fixing block 44 is fixedly connected to the mounting base plate 1, and the lower end of the guide post 42 is arranged on the guide post fixing block 44. The two ends of the spring 45 are respectively connected to the guide post fixing block 44 and the sliding plate 41, and the spring 45 is used to provide elastic restoring force after the upper slider 5 is lifted.
