[0002] The production process of a machine refers to the entire process of turning raw materials (or semi-finished products) into finished products. For machine production, this includes the transportation and storage of raw materials, production preparation, blank manufacturing, parts processing and heat treatment, product assembly and debugging, painting and packaging, etc. The production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize and guide production, viewing the production process as a production system with inputs and outputs. A search revealed existing technology (Announcement No.: CN202320407467.2) for a machining positioning device. The document describes a device where "a left bearing is connected through the middle of the left slide plate, a right bearing is connected through the middle of the right slide plate, a left fastening rod and a right fastening rod are connected through the middle of the left and right bearings, a left main ring and a left middle groove are connected through both ends of the left fastening rod, a right main ring and a right auxiliary ring are connected through both ends of the right fastening rod, a left half-ring is fixed to the end of the left fastening rod, and a right half-ring is fixed to the end of the right fastening rod. The left and right half-rings clamp and fix the raw material, regardless of..." The size of the raw material and the distance between the left and right semi-rings can be changed. The left fastening rod can be moved left and right by rotating the left main ring and the left auxiliary ring, and the right fastening rod can be moved by rotating the right main ring and the right auxiliary ring. The left and right fastening rods have grooves in the middle, allowing the raw material to be adjusted at any angle during processing.

This allows for processing, and the angle adjustment is time-saving, labor-saving, and convenient, solving the problems of previous angle adjustment difficulties, complex angle adjustment, and inconvenient operation. However, in the existing technology, the arc-shaped clamping surfaces of the left and right semi-rings are prone to causing slippage and displacement of the clamped workpiece when the angle is adjusted, resulting in unstable positioning. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a machining positioning device is provided to solve the problem that the arc-shaped clamping surfaces of the left and right semi-rings in the existing technology can easily cause the workpiece to slide or shift when the angle is adjusted, resulting in unstable positioning.

[0004] To achieve the above objectives, a machining positioning device is provided, comprising: a positioning frame, wherein a support plate is welded to the front surface of the positioning frame.

[0005] The right side of the support plate is connected to a positioning plate via a transmission column. An outer limiting column and an inner limiting column are distributed through the right end face of the positioning plate. A first small air pump and a second small air pump are installed on the left side of the positioning plate. An annular air guide cavity is opened inside the positioning plate. The right end of the annular air guide cavity is connected to a telescopic groove. The outer limiting column and the inner limiting column are limited and connected to the telescopic groove via a piston block. A side pressure plate is distributed on the right end of the positioning plate. A drive plate is connected to the right side of the side pressure plate via a connecting column.

[0006] Furthermore, a controller is provided on the upper surface of the positioning frame, and an electric slide is embedded in the front surface of the positioning frame, with a drive plate slidably connected to the front end of the electric slide.

[0007] Furthermore, a servo motor is fixed to the left side of the support plate, and the right side of the servo motor is connected to the transmission column via a coupling; and a transmission column is fixed to the middle of the left side of the positioning plate.

[0008] Furthermore, an infrared locator is installed on the left side of the positioning frame, and a receiver is fixed on the side of the support plate; and the infrared locator and the receiver are positioned correspondingly.

[0009] Furthermore, an anti-slip pad is adhered to the right side of the positioning disk, an elastic pad is adhered to the left side of the side pressure plate, and the inner and outer limiting posts are arranged in a ring from the inside to the outside on the right side of the positioning disk.

[0010] Furthermore, a piston block is fixed to the left side of the outer limiting post and the inner limiting post; and the outer side of the piston block is in close contact with the telescopic groove.

[0011] Furthermore, the first small air pump and the second small air pump are respectively connected to air pipe one and air pipe two; and air pipe one and air pipe two are respectively connected to the annular air guide cavity.

[0012] The beneficial effects of this utility model are as follows: the machining positioning device of this utility model uses a first small air pump and a second small air pump to deliver pressurized gas into the positioning disk cavity. The pressurized gas pushes the outer and inner limit posts, which are not held by the workpiece, through the right side of the positioning disk. This allows multiple limit posts to position the workpiece between the positioning disk and the side pressure plate, thus achieving an anti-slip positioning device. This ensures that the positioning device can efficiently and stably position and clamp the workpiece, while also facilitating the positioning of workpieces of various shapes. It prevents the workpiece from sliding or shifting when adjusting the machining angle, enhances the stability of the machining positioning device, and improves the machining accuracy.

[0019] Reference Figures 1 to 5 As shown, this utility model provides a machining positioning device, including: a positioning frame 1, and a support plate 11 welded to the front surface of the positioning frame 1.

[0020] The right side of the support plate 11 is connected to the positioning plate 2 via the transmission column 22. The right end face of the positioning plate 2 has an outer limiting column 21 and an inner limiting column 23 distributed through it. The left side of the positioning plate 2 is equipped with a first small air pump 3 and a second small air pump 31. The positioning plate 2 has an annular air guide cavity 25 inside. The right end of the annular air guide cavity 25 is connected to a telescopic groove 26. The outer limiting column 21 and the inner limiting column 23 are connected to the telescopic groove 26 through a piston block 29. The right end of the positioning plate 2 has a side pressure plate 4. The right side of the side pressure plate 4 is connected to the drive plate 41 via a connecting column 43.

[0021] First, align one side of the workpiece with the right side of the positioning plate 2. Control the electric slide 13 on the front side of the positioning frame 1 to move the drive plate 41 to the left, so that the left end of the side pressure plate 4 contacts the other side of the workpiece, and firmly presses the workpiece against the side of the positioning plate 2. Then, energize the first small air pump 3 and the second small air pump 31 to generate pressurized gas, which is delivered into the inner cavity of the positioning plate 2 through the first air pipe 32 and the second air pipe 33. The pressurized gas pushes the piston block 29 in the telescopic groove 26 to the right, so that the outer limit post 21 and the inner limit post 23, which are not pressed by the workpiece on the side of the positioning plate 2, pass through the right side of the positioning plate 2. The multiple outer limit posts 21 and inner limit posts 23 that pass through restrict the position of the workpiece and prevent the workpiece from shifting or sliding when the angle is adjusted. The workpiece in the positioning clamp can then be processed manually using processing equipment.

[0022] In this embodiment, a controller 12 is provided on the upper surface of the positioning frame 1, and an electric slide 13 is embedded in the front surface of the positioning frame 1. A drive plate 41 is slidably connected to the front end of the electric slide 13.

[0023] In a preferred embodiment, the controller 12 controls the rotation of the servo motor 14 and the start and stop of the electric slide table 13. The electric slide table 13 drives the drive plate 41 to move left and right, causing the drive plate 41 to move the side pressure plate 4 towards the positioning plate 2, clamping the workpiece on the right side of the positioning plate 2.

[0024] In this embodiment, a servo motor 14 is fixed on the left side of the support plate 11, and the right side of the servo motor 14 is connected to the transmission column 22 via a coupling 24; and the transmission column 22 is fixed in the middle of the left side of the positioning plate 2.

[0025] As a preferred implementation, the servo motor 14 drives the transmission column 22 to rotate through the coupling 24, which in turn drives the positioning disk 2 to rotate, so that the workpiece clamped on the side of the positioning disk 2 and the side pressure plate 4 rotate synchronously, thereby achieving the effect of adjusting the positioning angle of the workpiece and making it easier for the machining personnel to perform machining on the positioned and clamped workpiece.

[0026] In this embodiment, an infrared locator 28 is installed on the left side of the positioning frame 1, and a receiver 15 is fixed on the side of the support plate 11; and the infrared locator 28 and the receiver 15 are positioned correspondingly.

[0027] In a preferred embodiment, the infrared locator 28 is convenient to emit infrared signals, and the receiver 15 receives the infrared signals emitted by the infrared locator 28, so as to reset the rotated positioning disk 2.

[0028] In this embodiment, an anti-slip pad 27 is adhered to the right side of the positioning disk 2, and an elastic pad 42 is adhered to the left side of the side pressure plate 4. The inner limiting post 23 and the outer limiting post 21 are arranged in a ring from the inside to the outside on the right side of the positioning disk 2. A piston block 29 is fixed to the left cylindrical surface of the outer limiting post 21 and the inner limiting post 23; and the outer side of the piston block 29 is in close contact with the telescopic groove 26.

[0029] As a preferred implementation, the anti-slip pad 27 serves to prevent slippage between the right side of the positioning disk 2 and the side of the clamped workpiece. Multiple limiting posts 23 and the outer limiting post 21 can extend beyond the right side of the positioning disk 2 according to the shape of the clamped workpiece, allowing the inner limiting post 23 and the outer limiting post 21, which are not pressed by the workpiece, to pass through, thereby limiting the displacement of the workpiece and positioning it on the right side of the positioning disk 2. This ensures efficient and stable positioning and clamping of the workpiece by the positioning device, while also facilitating the positioning of workpieces of various shapes. It prevents the clamped workpiece from slipping or shifting when adjusting the machining angle, enhancing the stability of the machining positioning device and improving the machining accuracy.

[0030] In this embodiment, the first small air pump 3 and the second small air pump 31 are respectively connected to air pipe 32 and air pipe 33; and air pipe 32 and air pipe 33 are respectively connected to the annular air guide cavity 25.

[0031] In a preferred embodiment, the first small air pump 3 and the second small air pump 31 deliver pressurized gas into the four sets of annular air guide chambers 25 through air pipe 1 32 and air pipe 2 33, so that the annular air guide chambers 25 deliver the pressurized gas to the telescopic groove 26. The pressurized gas entering the telescopic groove 26 pushes the piston block 29 in the groove to move to the right, so that the outer limiting post 21 or the inner limiting post 23 passes through the right side of the positioning plate 2.

[0032] This utility model's machining positioning device effectively solves the problem in the prior art where the arc-shaped clamping surfaces of the left and right semi-rings easily cause slippage and displacement of the clamped workpiece when adjusting its rotation angle, resulting in unstable positioning. It achieves an anti-slip function, ensuring efficient and stable workpiece clamping. It also facilitates the positioning of workpieces of various shapes, preventing slippage and displacement of the clamped workpiece when adjusting the machining angle, enhancing the stability of the machining positioning device, and improving machining accuracy. It is suitable for machining positioning devices.
