Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology and relates to a clamping fixture for special parts, specifically a replaceable clamping and positioning device for irregularly shaped plug switch housing parts. Background Technology

[0002] like Figures 1-3 As shown, the part blank to be machined is a casting with an irregular structure, and its orientation is difficult to determine. The conventional machining method is as follows: before machining, the machining datum is determined by scribing lines. The fitter uses surface M1 for positioning, levels surface M2, and then clamps surface M3. Line aa is determined by dimension L1, line bb by dimension L2, and line cc by dimension L3, thus establishing the machining datum. During machining, the finishing datum is determined by aligning the datum lines. The drawbacks of this method are: numerous fixture flips during scribing, errors during the scribing and machining processes, and difficulty in meeting the requirements of mass production. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a clamping and positioning device for irregularly shaped plug switch housing parts. This device is lightweight, easy to operate, and saves on scribing steps, allowing the parts to be processed in one clamping operation on a horizontal machining center. Its use can improve production efficiency and overcome the shortcomings of traditional blank scribing and line-finding processing, which results in large errors and low processing efficiency.

[0004] The technical solution of this utility model is as follows:

[0005] A clamping and positioning device for irregularly shaped plug-in switch housing parts, used for machining plug-in switch housing parts, includes a base plate, a replaceable pressure plate, a replaceable support, and clamping screws; the base plate has a bottom surface and a back surface for positioning the plug-in switch housing part; the replaceable pressure plate is connected to the upper side of the base plate, and the inner side of the replaceable pressure plate mates with the motor mounting surface on the front side of the plug-in switch housing part; the replaceable support is connected to the lower side of the base plate, and the replaceable support has holes for installing clamping screws, the ends of which press against the surface of the plug-in switch housing part.

[0006] Furthermore, the upper half of the replaceable pressure plate has a square structure, and the lower half of the replaceable pressure plate has a semi-circular groove structure, with the semi-circular groove corresponding to the circular mounting port of the motor mounting base of the plug switch housing part.

[0007] Furthermore, the structure of the replaceable pressure plate's semi-circular groove plate extends support bodies to both sides, and the support bodies avoid the four threaded pillars of the motor mounting base of the plug switch housing parts.

[0008] Furthermore, it also includes a replaceable support block and a double-ended screw. The replaceable pressure plate is connected to the base plate through the double-ended screw, and the replaceable support block is located between the replaceable pressure plate and the base plate.

[0009] Furthermore, one end of the replaceable support block is mounted on the top of the base plate, and the other end of the replaceable support block extends out of the base plate and contacts the replaceable pressure plate.

[0010] Furthermore, the replaceable pressure plate, replaceable support, and replaceable support block are all equipped with replacement bodies of different sizes.

[0011] Technical effects of this utility model:

[0012] The above technical solution uses two positioning surfaces on the base plate to locate the blank reference. During machining, the operator only needs to align the two positioning surfaces on the base plate after the fixture is installed to determine the Y / Z coordinate origin. After the part is clamped, only the X coordinate origin needs to be determined using a disc dial indicator, which easily determines the machining origin. Using this positioning method, the operator's operation is simple, the machining zero point determination time is short, errors in fitter marking and machining line finding are eliminated, and product quality is stable. At the same time, due to the use of a replaceable support design, there is no need to disassemble the fixture during model changeover; only the support needs to be replaced, which greatly improves the efficiency of model changeover for similar parts.
