Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts processing, in particular to a clamping device pushing and clamping mechanism. Background Art

[0002] Mechanical parts processing is a vital link in the manufacturing industry. It transforms raw materials into parts of the required shape, size and surface quality through various precision processing methods. In the processing of mechanical parts, it is often necessary to use a fixture to advance the clamping mechanism.

[0003] During use, the existing clamp pushing and clamping mechanism is usually not convenient to adjust its horizontal and vertical angles during the pneumatic clamping process, resulting in a relatively single adjustment range of its main body, which easily affects the clamping effect of its main body. In order to solve the above technical problems, we have designed a clamp pushing and clamping mechanism. Utility Model Content

[0004] The purpose of the utility model is to provide a clamp propulsion clamping mechanism, which has the advantage of being easy to adjust in multiple directions so as to achieve a good clamping effect, and solves the problem that the clamping effect is affected due to the inability to perform multi-directional adjustment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamp advancing and clamping mechanism, comprising a fixed block, a clamping mechanism is provided on the top of the fixed block, the clamping mechanism comprises a cylinder assembly, a pull rod assembly is fixedly installed on the surface of the cylinder assembly, a dead point axis pin is provided through the left side of the front side of the cylinder assembly, a positioning piece is fixedly installed on the left side of the cylinder assembly, a second adjusting mechanism is provided at the bottom of the fixed block, the second adjusting mechanism comprises a top shell, a transmission shaft is provided through the right side of the top shell, a first adjusting mechanism is provided on the right side of the top shell, the first adjusting mechanism comprises a longitudinal shell, a dual-axis motor is horizontally welded at the center of both sides of the inner cavity of the longitudinal shell, the output ends of the top and bottom of the dual-axis motor are connected to the output shaft by bolts, and an extension rod is provided through the side of the output shaft away from the dual-axis motor.

[0006] Preferably, a cross positioning cone is welded to the bottom of the extension rod, and an axial rod for use with the cross positioning cone is provided through the bottom of the longitudinal shell.

[0007] Preferably, a fixing piece is provided on the surface of the extension rod, and the fixing piece extends from a side of the extension rod to the outside of the longitudinal shell.

[0008] Preferably, fixing plates are welded to the top and bottom of the right side of the longitudinal shell, and electric push rods are connected between the opposite sides of the two fixing plates by bolts. The side of the electric push rod away from the fixing plate is fixedly connected to the fixing piece by bolts, and a sliding through hole is opened on the right side of the longitudinal shell for use with the fixing piece.

[0009] Preferably, the top fixing sleeve on the surface of the extension rod is provided with a first bevel gear, and the right fixing sleeve on the surface of the transmission shaft is provided with a second bevel gear used in conjunction with the first bevel gear.

[0010] Preferably, the left side of the transmission shaft is movably connected to the left side of the inner cavity of the top shell through a bearing, and fixed sleeves are provided on both sides of the surface of the transmission shaft. The top of the fixed sleeve passes through the outside of the top shell and is welded with a support member, and the top of the support member is welded to the bottom of the fixed block.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. The utility model cooperates with the pull rod assembly, the cylinder assembly, the dead point shaft pin, the positioning member, the clamping mechanism, the transmission shaft, the top shell, the support member, the fixing sleeve and the first bevel gear. During use, the lower electric push rod can be started by an external controller, so that its output end drives the lower extension rod to move downward through the lower fixing member, so that it drives the cross positioning cone to fit into the inner cavity of the cross positioning groove opened at the top of the axial rod, so that under the action of the dual-axis motor driving the output shaft to rotate, the axial rod is driven to rotate through the extension rod and the cross positioning cone.

[0013] 2. The utility model cooperates with the output shaft, the extension rod, the fixing piece, the cross positioning cone, the electric push rod, and the fixing plate. During use, the axial rod can be driven to rotate by the extension rod and the cross positioning cone to adjust its horizontal angle. When it is necessary to rotate its vertical angle, the user can start the upper electric push rod through the external controller, so that its output end drives the upper extension rod to move downward through the upper fixing piece, so that it drives the first bevel gear to engage the second bevel gear to drive the transmission shaft to rotate, thereby driving the angle adjustment through the fixing sleeve.
