Description

Technical Field

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

[0002] Parts clamping equipment is often used during the processing of mechanical parts, so that the parts can be better processed. Fixtures and clamping equipment refer to devices used to fix the processing object during the mechanical manufacturing process so that it occupies the correct position for construction or inspection.

[0003] Among them, the parts clamping equipment for hardware tool processing disclosed in application number CN202221243556.X is also an increasingly mature technology. The two side clamps are driven by the elastic force of two micro springs to clamp the hardware tools. Since the opposite surfaces of the two side clamps are fixedly installed with clamping sleeves, the two clamping sleeves will first contact the hardware tools and clamp the hardware tools, thereby improving the clamping strength of the two side clamps. By using the two side clamps to simply clamp the hardware tools, it plays a certain auxiliary role, thereby improving the convenience of clamping the device.

[0004] A search of CN202220714926.7 disclosed a clamping device for parts, which is also an increasingly mature technology. The clamping assembly can clamp and fix both regular and special-shaped parts. The clamping assembly is composed of four clamping plates, and the four clamping plates can be operated separately. The outer column is connected to the clamping plate through a limiting axis, and the angle between the outer column and the clamping plate can be adjusted through the limiting axis, so that the clamping of parts is more flexible, and the limiting axis can be clamped and fixed by rotating the limiting screw. An arc-shaped support block is also provided in the workbench, which can support longer parts. At the same time, the electric telescopic rod can be adapted and adjusted according to the height of the parts, making the parts more stable as a whole.

[0005] Based on this, we agree with the advantages of the above products, but there are still the following defects:

[0006] These two clamping devices cannot flip the workpiece, and the workpiece needs to be loosened and then re-clamped to flip it, which wastes a lot of time and reduces work efficiency. Utility Model Content

[0007] The utility model aims to provide a parts clamping device to solve the problem of reduced working efficiency proposed by the above background technology.

[0008] The embodiment of the utility model provides a part clamping device, including a clamping device and a rotating device;

[0009] The clamping device comprises a cylinder, a piston rod of the cylinder is fixedly connected to a mounting block, a mounting hole is provided on one side of the mounting block, a clamping block is movably installed inside the mounting hole and a positioning hole is provided on the top, a limiting hole matching the positioning hole is provided on the top of the mounting block, a screw is installed on the top of the limiting hole, and the mounting hole is communicated with the limiting hole;

[0010] The rotating device comprises an electric motor, the output end of the electric motor is provided with a main bevel gear, the main bevel gear meshes with a transmission auxiliary bevel gear, and the rotating shaft of the auxiliary bevel gear passes through a fixed seat and is connected to one end of the cylinder.

[0011] In this embodiment, the movement of the cylinder drives the synchronous movement of the mounting block, the mounting hole facilitates the installation of the clamping block, and it is also convenient to replace different types of clamping blocks. The positioning hole and the limit hole overlap and the clamping block is fixed with screws. The main bevel gear is driven to rotate by the motor, and the main bevel gear engages the transmission sub-bevel gear, thereby causing one end of the cylinder to rotate synchronously. The rotation of the cylinder drives the mounting block and the clamping block to rotate synchronously, thereby adjusting the angle of the clamped parts.

[0012] In one implementation of the utility model, one side of the cylinder is connected to a fixing seat, the rotating shaft is located outside the fixing seat and a bearing sleeve is installed, and the clamping device and the rotating device are symmetrically installed.

[0013] In this solution, the bearing sleeve is used to reduce the direct contact between the rotating shaft and the fixed seat, thereby reducing the friction. The clamping device and the rotating device are symmetrically installed to facilitate clamping of parts and make the operation of the equipment more stable, thereby improving work efficiency and precision.

[0014] In an implementation manner of the utility model, the bottom of the fixing seat is connected to a work table, and reinforcing ribs are installed between the supporting legs of the work table.

[0015] In this solution, the stiffness and stability of the supporting legs can be increased by reinforcing ribs, thereby reducing the shaking and wobbling of the work table during use and preventing accidents caused by the shaking of the work table.

[0016] In one embodiment of the utility model, a plurality of buffer springs are installed in the middle of the top of the work table and are connected to a bottom plate at the top, and a rubber pad is connected to the top of the bottom plate and the outside of the clamping block.

[0017] In this solution, the buffer spring and the rubber pad can play a shock-absorbing role. When the base plate is impacted or vibrated, the impact of these forces on the work table can be reduced, thereby reducing noise and vibration.

[0018] In one implementation of the utility model, a protective shell is installed on the outside of the motor and connected to two sides of the work table. The four corners of the bottom of the work table are equipped with fixed universal wheels and a shock-absorbing spring is installed on the top.

[0019] In this solution, the appearance of the motor is protected from external damage by a protective shell, the work table can be easily moved by the fixable universal wheels, and the universal wheels can also be locked to fix the table. The shock-absorbing spring can reduce the instability and safety hazards caused by external vibrations on the work table.

[0020] In one implementation of the utility model, a switch panel is installed on the top side of the work table, and a cylinder switch and a motor switch are installed on the top of the switch panel respectively. The cylinder switch and the motor switch are electrically connected to the cylinder and the motor respectively, and the switch panel is electrically connected to an external power supply.

[0021] In this solution, the switch panel saves the staff from operating steps, and the cylinder switch and the motor switch are used to protect the cylinder and the motor respectively.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] When the angle needs to be adjusted, the main bevel gear is driven to rotate by the motor, and the main bevel gear is meshed with the transmission sub-bevel gear. Since the rotating shaft of the sub-bevel gear passes through the fixed seat and is connected to one end of the cylinder, one end of the cylinder is rotated synchronously. The rotation of the cylinder drives the mounting block and the clamping block to rotate synchronously, so that the angle of the clamped parts can be adjusted;

[0024] When clamping is required, the positioning hole of the clamping block overlaps the limiting hole of the mounting block, and the clamping block is fixed with screws. The movable installation of the clamping block facilitates quick installation and disassembly, and facilitates replacement of different types of clamping blocks. The mounting blocks are driven to move synchronously by the mutual approach of the cylinders, so that the clamping block clamps the parts. BRIEF DESCRIPTION OF THE DRAWINGS
