[0002] With the rapid development of modern manufacturing, the requirements for machine tool processing accuracy and efficiency are getting higher and higher. Traditional machine tool positioning devices have many shortcomings. The general positioning device uses a locking bolt to allow the pressure plate to press on the workpiece, thereby positioning the workpiece, which requires manual operation and adjustment. The positioning accuracy is not high, the operation is complicated and the efficiency is low. With the continuous advancement of automation and intelligent technology, the market demand for machine tool positioning devices that can improve production efficiency and reduce labor costs is growing. Utility Model Content

[0003] The utility model aims to provide a machine tool positioning device and a processing machine tool which can perform rapid and accurate positioning and simplify the operation process and can improve production efficiency.

[0004] A machine tool positioning device is used for processing machine tools, including a plurality of positioning fixtures and a plurality of positioning components. The positioning fixtures and the positioning components are installed on the processing machine tool. The positioning components include a positioning plate and a positioning pin. The processing workpiece is connected to the positioning plate through the positioning pin. At least two positioning fixtures are respectively arranged on both sides of the processing workpiece.

[0005] In the above scheme, a positioning hole is opened on the workpiece, and one end of the positioning pin is inserted into the positioning hole of the workpiece and the other end is inserted into the positioning plate, which can ensure the accurate positioning of the workpiece. At least two positioning fixtures are arranged on both sides of the workpiece. The positioning fixtures can automatically clamp the workpiece, thereby realizing fast and accurate positioning of the workpiece, thereby ensuring the stability and accuracy of the workpiece during the processing, thereby improving the processing quality, and the operation process is also simplified, which can reduce the time for clamping and adjusting the workpiece, thereby improving the overall processing efficiency.

[0006] Furthermore, the positioning plate is provided with a plurality of mounting holes, and the positioning pins are inserted into the mounting holes.

[0007] In the above scheme, the multiple mounting holes provided on the positioning plate enable the positioning pin to be flexibly adjusted to be inserted into the positioning plate according to the different workpieces to be processed. The multiple mounting holes provide a variety of options for inserting the positioning pins, thereby enhancing the flexibility of the positioning assembly and enabling the machine tool positioning device to adapt to workpieces of different sizes and shapes.

[0008] Furthermore, the positioning fixture includes a driving member, a connecting rod, a rotating assembly and a pressure rod, the telescopic end of the driving member is rotatably connected to the connecting rod, the rotating assembly is rotatably connected to the connecting rod, and the pressure rod is installed at one end of the connecting rod away from the driving member.

[0009] In the above scheme, the driving member can be a cylinder, and the telescopic end of the driving member is rotatably connected to the connecting rod. In this way, when the telescopic end of the driving member is extended and retracted, the connecting rod will deflect, thereby driving the pressure rod to rise and fall, so that the pressure rod can loosen or clamp the workpiece. The rotating assembly is rotatably connected to the connecting rod. When the connecting rod deflects, the rotating assembly also rotates accordingly. When the pressure rod clamps the workpiece, the rotating assembly can play a supporting role, thereby ensuring the stability of the connecting rod and the pressure rod. The automated driving member can respond quickly, reduce the time for clamping and unloading the workpiece, and improve production efficiency. In addition, the automated positioning fixture reduces dependence on operators and reduces labor costs.

[0010] Furthermore, the telescopic end of the driving member is connected to a hinge block, the hinge block is provided with a first through hole, the end of the connecting rod is provided with a connecting groove, the hinge block is passed through the connecting groove, and the connecting rod is provided with a second through hole corresponding to the first through hole.

[0011] In the above scheme, the hinge block realizes the rotational connection between the connecting rod and the driving member. The hinge block is inserted into the connecting groove at the end of the connecting rod. The design of the hinge block and the connecting groove can optimize the space utilization, making the positioning fixture more compact. The connecting rod and the hinge block are hinged by passing the second through hole of the connecting rod and the first through hole of the hinge block through a pin, so that the deflection angle of the connecting rod can be adjusted, and then the height of the pressure rod can be adjusted.

[0012] Furthermore, the rotating assembly includes a rotating seat and two rotating members, one end of the two rotating members is connected to the rotating seat, and the other ends of the two rotating members are respectively connected to two sides of the connecting rod.

[0013] In the above scheme, one end of the two rotating parts is connected to the rotating seat, and the other end is connected to the two sides of the connecting rod respectively. When the connecting rod deflects, the rotating parts produce a certain deflection angle along with the deflection of the connecting rod, thereby providing a more stable support for the connecting rod and reducing the swing of the connecting rod when tightening or loosening the workpiece.

[0014] Furthermore, the rotating seat includes a mounting block and a connecting block, and third through holes are provided at both ends of the mounting block, and the third through holes correspond to the fixing holes on the driving member. The connecting block is perpendicular to the mounting block, and a fourth through hole connected to the rotating member is provided on the connecting block.

[0015] In the above scheme, the third through holes at both ends of the mounting block correspond to the fixing holes on the driving member, which makes it convenient to fix the rotating seat. The mounting block and the connecting block are integrally formed for easy processing. The connecting block is perpendicular to the mounting block, and the rotational connection between the connecting block and the rotating member is achieved through the fourth through hole. The overall structure is simple, maintenance work becomes easier, problems can be quickly located, and necessary repairs or replacements can be performed.

[0016] Furthermore, the pressing rod includes a rod portion and a pressing portion, the rod portion is connected to the connecting rod, the pressing portion is integrally formed with the rod portion, and the pressing portion is used to press and process the workpiece.

[0017] In the above scheme, the pressing part and the rod part are integrally formed, which reduces extra steps in the manufacturing process, such as welding or assembly, and simplifies the production process. The rod part and the pressing part are both cylindrical, which is more convenient to process. The diameter of the rod part is smaller than the diameter of the pressing part, so that the rod part is convenient to connect with the connecting rod, and the pressing part can also better press the workpiece for processing.

[0018] A processing machine tool comprises a machine tool positioning device as described in any one of the above schemes.

[0019] In the above scheme, the stability and accuracy of the workpiece during the processing are ensured through the precise machine tool positioning device, thereby improving the processing quality. The automated and simplified positioning process reduces the time for workpiece clamping and adjustment, thereby improving the overall processing efficiency.

[0020] The utility model provides a machine tool positioning device and a processing machine tool that can perform fast and accurate positioning and simplify the operation process, thereby improving production efficiency. A positioning hole is opened on the processing workpiece, and one end of the positioning pin is inserted into the positioning hole of the processing workpiece and the other end is inserted into the positioning plate, which can ensure accurate positioning of the processing workpiece.
