Description

Technical Field

[0001] This utility model relates to a positioning device, specifically a center auxiliary positioning device for thread milling cutter preparation, belonging to the field of milling cutter preparation technology. Background Technology

[0002] A center auxiliary positioning device for thread milling cutter preparation is a key piece of equipment used in the thread milling cutter manufacturing process to ensure the accuracy of the cutter's center reference point. The main purpose of this device is to precisely position and fix the center of the cutter during manufacturing, ensuring the accuracy and stability of the milling process. This device typically consists of several components, including a support, a clamping support, a pressing part, and a related power mechanism.

[0003] In existing technologies, such as the milling cutter precision positioning seat for vertical machining centers disclosed in CN215698305U, a fixed connecting column is included. The upper middle of the fixed connecting column is fixedly connected to an upper conical connecting column for connection work. The lower end of the fixed connecting column is fixedly connected to an annular groove fixing column for fixing work, and the lower end of the annular groove fixing column is fixedly connected to a lower fixing column for fixing work. Through the contact of multiple semi-circular arc-shaped locking pins in the elastic fixing sleeve with the upper outer wall of the milling cutter, an outward pushing force is generated. This causes the elastic groove to open, and simultaneously causes the elastic sleeve to bulge outward and contact the inner wall of the fixing slot. Through action and reaction forces, the elastic fixing sleeve can then fasten the milling cutter, improving the fastening effect of the milling cutter precision positioning seat. This facilitates the tightening operation of the fastening bolts by the operator, saving operator time.

[0004] While the above-mentioned technical solutions can improve the fastening effect of the milling cutter precision positioning seat, thereby facilitating the tightening operation of the fastening bolts and saving the operator's time, they are not convenient for fixing materials of different diameters during use. This results in the need to change the device when positioning materials of different diameters. In view of this, a center auxiliary positioning device for thread milling cutter preparation is provided to overcome the above-mentioned defects. Utility Model Content

[0005] This invention provides a center auxiliary positioning device for thread milling cutter preparation to solve the problem that it is inconvenient to fix materials of different diameters during use, which leads to the need to change the device when positioning materials of different diameters.

[0006] The present invention achieves the above objectives through the following technical solution: a center auxiliary positioning device for preparing thread milling cutters, comprising a device housing, a limit ring fixed at one end of the device housing, a positioning mechanism for positioning the workpiece provided on the outer wall of the device housing, and a clamping mechanism for pressing the workpiece provided inside the device housing;

[0010] As a further improvement of this utility model, the outer wall of the fixing rod is equipped with a fixing bolt that is inserted and connected to the limiting hole.

[0011] As a further improvement of this utility model: the clamping mechanism includes a mounting groove, which is formed inside the housing of the device.

[0012] As a further improvement of this utility model, a compression spring is fixed to the inner wall of the mounting groove.

[0013] As a further embodiment of this utility model: the end of the compression spring is connected to a limit block, and a clamping element is fixed on one side of the limit block.

[0014] The beneficial effects of this utility model are: by turning the adjusting screw, with the cooperation of the fixed bearing, the clamping plate can be driven to move, so that the clamping plate and the outer surface of the workpiece come into contact, thereby clamping and positioning the workpiece, which is convenient for positioning workpieces of different diameters and enabling the center of the workpiece to be positioned.

[0015] By unscrewing the fixing bolts on the fixing rod, the fixing bolts and the limiting holes on the connecting block are separated, thus releasing the fixing of the connecting block. With the cooperation of the mounting cavity, the outer shell of the device and the fixing rod can be disassembled and separated, making it convenient to use and improving its practicality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1 to 4 As shown, a center auxiliary positioning device for preparing thread milling cutters includes a device housing 1, a limit ring 2 fixed at one end of the device housing 1, a positioning mechanism for positioning the workpiece on the outer wall of the device housing 1, and a clamping mechanism for clamping the workpiece inside the device housing 1.

[0023] The positioning mechanism includes four adjusting screws 3, which are symmetrically installed on the outer wall of the device housing 1. Each of the four adjusting screws 3 has a fixed bearing 31 fitted at its end. A clamping plate 32 is fixed to the outer surface of the fixed bearing 31. A connecting cavity 33 is provided inside the device housing 1. A connecting block 4 is fixed to the other end of the device housing 1. A limit hole 5 is provided on the upper surface of the connecting block 4. A fixing rod 7 is connected to the end of the connecting block 4. An installation cavity 6 is provided inside the fixing rod 7 for insertion and connection with the connecting block 4. A fixing bolt 8 is installed on the outer wall of the fixing rod 7 for insertion and connection with the limit hole 5. The adjusting screws 3 can be turned to rotate, thus fixing the position. With the cooperation of bearing 31, the clamping plate 32 can be driven to move, so that the clamping plate 32 contacts the outer surface of the workpiece, thereby clamping and positioning the workpiece. This facilitates the positioning of workpieces of different diameters and enables the center of the workpiece to be positioned. Furthermore, the workpiece can be readjusted after positioning by adjusting the adjusting screw 3. When the device needs to be disassembled for maintenance, the fixing bolt 8 on the fixing rod 7 can be unscrewed, so that the fixing bolt 8 and the limiting hole 5 on the connecting block 4 can be separated, thus releasing the fixation of the connecting block 4. With the cooperation of the mounting cavity 6, the outer shell 1 and the fixing rod 7 of the device can be disassembled and separated, making it convenient to use and improving its practicality. Example 2

[0024] In addition to all the technical features in Embodiment 1, this embodiment also includes: a clamping mechanism including a mounting groove 9, which is opened inside the device housing 1. A clamping spring 91 is fixed to the inner wall of the mounting groove 9. The end of the clamping spring 91 abuts against and connects to a limit block 92. A clamping member 93 is fixed to one side of the limit block 92. When the workpiece to be processed is inserted into the device housing 1, the limit ring 2 can play an auxiliary limiting role, so that one end of the workpiece is in the connecting cavity 33. After the workpiece is pushed in, the end of the workpiece presses the clamping member 93 to move. When the clamping member 93 moves, it will drive the limit block 92 to move, thereby compressing the clamping spring 91 in the mounting groove 9.

[0025] Working principle: Before using the center auxiliary positioning device for thread milling cutter preparation, first place the device in a suitable position and fix the fixing rod 7 with external bolts to fix the device. When using it, insert the workpiece to be processed into the device housing 1. The limit ring 2 can play an auxiliary limiting role, so that one end of the workpiece is in the connecting cavity 33. After pushing the workpiece in, the end of the workpiece presses the clamping member 93 to move. When the clamping member 93 moves, it will drive the limit block 92 to move, thereby compressing the clamping spring 91 in the mounting groove 9. At this time, the adjusting screw 3 can be turned to rotate, and the fixed bearing 31 is fixed. With the cooperation of the clamping plate 32, the clamping plate 32 can be driven to move, so that the clamping plate 32 contacts the outer surface of the workpiece, thereby clamping and positioning the workpiece. This facilitates the positioning of workpieces of different diameters and enables the center of the workpiece to be positioned. The workpiece can be adjusted again after positioning by adjusting the adjusting screw 3. When the device needs to be disassembled for maintenance, the fixing bolt 8 on the fixing rod 7 can be unscrewed, so that the fixing bolt 8 and the limiting hole 5 on the connecting block 4 can be separated, thus releasing the fixation of the connecting block 4. With the cooperation of the mounting cavity 6, the outer shell 1 and the fixing rod 7 of the device can be disassembled and separated, which is convenient for use and improves practicality.
