Example Embodiment

[0026] Example one:

[0027] On the contour 2 of the workpiece 18 of the present invention, a rough positioning surface 1 is provided on the side; at a corresponding position on the clamp, a rough positioning rod 16 is set to contact it, and the coarse positioning rod 16 is formed by a positioning rod seat 17 Fixed, the positioning rod base 17 is fixed on the clamp base 11.

[0028] The rough positioning is completed by the initial fit of the central alignment pin 9 and the rough positioning rod 16. There are generally two coarse positioning rods 16.

Example Embodiment

[0029] Embodiment two:

[0030] The contour 2 of the workpiece 18 of the present invention is provided with a fine positioning surface 8 on the side; in the corresponding position on the clamp, a pneumatic positioning plate 10 is provided. When performing fine positioning, the pneumatic positioning plate 10 and The lateral fine positioning surface 8 contacts.

[0031] Then use the pneumatic device to make the side fine positioning surface 8 and the pneumatic positioning plate 10 close contact on the part; start the pneumatic clamping device press figure 1 Clamping is performed as shown; the center positioning pin 9 is pulled out to complete the positioning of the workpiece 18. With this method, the positioning is accurate and reliable, and it is convenient and quick to use.

Example Embodiment

[0032] Embodiment three:

[0033] To figure 2 The workpiece 18 is shown as an example, and its processing operation steps are as follows:

[0034] First install it as figure 1 with image 3 The clamp shown; press the side rough positioning surface 1 of the workpiece 18 figure 1 After the position shown is close to the rough positioning rod 16, press the machined center to align the pin 9 image 3 In the method shown, insert the workpiece into the center through hole 7 to be processed; then, as figure 1 with image 3 As shown, the air cylinder behind the pneumatic positioning plate 10 is activated to realize the quick clamping and pushing of the pneumatic positioning plate 10 to ensure that the side precision positioning surfaces on the workpiece 18 are in contact with each other; then the clamping cylinder is started, and the pneumatic device is used for example figure 1 After the pneumatic clamping shown, the center alignment pin 9 is pulled out to complete the final precise po...

Abstract

The invention discloses a clamp used for self-positioning of the processing surfaces. The clamp is provided with a central positioning hole (15) and a central positioning bolt (9); when a workpiece (18) is positioned on the clamp, the central positioning bolt (9) is inserted into the central positioning hole (15) and the central through hole (7) of the workpiece (18) at the same time, so as to lead the central positioning hole (15) and the central through hole to be coaxial; the central positioning bolt (9) is removed when the workpiece (18) is being clamped and processed. The invention also discloses an operation method used for the clamp. By adopting the technical proposal and using the self-positioning of the processing surfaces, the positioning is exact and reliable; the usage is convenient and fast in combination with the clamping of the cylinder; by adopting the steps of initial positioning and precise positioning, the positioning is convenient and the final poison is exact; a plurality of processing surfaces can be processed by one-step clamping, and the position precision is easier to be ensured.

Description

technical field [0001] The invention belongs to the technical field of processing technology equipment for mechanical parts, and more specifically, the invention relates to a fixture for self-positioning of a processing surface. In addition, the present invention also provides an operation method of the clamp for positioning the processing surface itself. Background technique [0002] In the processing of light alloy die castings, when using CNC machining center CNC or special processing machine tools, a type of workpiece is often encountered. There are many parts to be processed, and parts with high requirements for shape tolerance and assembly accuracy. It often has a more prominent feature of symmetrical processing and assembly centered on the hole to be processed. This kind of parts often cannot meet the processing and assembly accuracy requirements of the parts due to the improper selection of the positioning reference and positioning method of the parts to be processe...
