[0027] The present invention will be described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 5As shown, the four-way frame processing and positioning device is used to fix the four-way frame 1, and a square hole 103 is opened in the middle of the square frame 101 of the four-way frame 1, and a plurality of top connection holes 104 are symmetrically arranged around the square frame 101. Specifically, the legs 102 of the four-way frame 1 are composed of an upper leg 105, a bent arm 106 and a lower leg 107, wherein: the bent arm 106 is arranged between the upper leg 105 and the lower leg 107; the lower leg 107 is offset outwardly and parallelly relative to the upper leg 105; the bottom of the lower leg 107 is turned outward to form a flange 108, the front of the upper leg 105 is provided with a plurality of upper front holes 109, the side of the upper leg 105 is provided with a plurality of upper side holes 110, the side of the lower leg 107 is provided with a plurality of lower side holes 111, and the flange 108 is provided with a bottom connection hole 112.

[0029] It should be noted that the upper and lower legs of the four-way frame are parallel and in different lines, and are provided with a variety of connection holes to facilitate the installation of the counterweight and enable the user to flexibly adjust the position of the counterweight to ensure that the rotation process remains smooth and without centrifugal force.

[0030] Since the four-way frame 1 is a thin-walled, special-shaped frame, there are many technical difficulties in the actual processing process, so it is necessary to adopt a specific tooling fixture, as shown in the figure, specifically including a base 2, a top pressure plate 3, a screw 4 and a nut 5, wherein: the four-way frame 1 is composed of a square frame 101 in the middle and legs 102 symmetrically arranged at the four corners; the base 2 is composed of a square table 201 and a disc 202, and a central threaded hole 203 is opened in the center of the square table 201 and the disc 202, and a positioning seat 204 for positioning the four-way frame 1 is arranged at the four corners of the square table 201, and a positioning boss 205 is arranged on the positioning seat 204; a positioning square table 301 for positioning the four-way frame 1 is arranged at the bottom of the top pressure plate 3, and a through hole 302 is opened in the center of the top pressure plate 3; the screw 4 passes through the through hole 302 of the top pressure plate 3 and the square frame 101 of the four-way frame 1 in turn and is installed in the central threaded hole 203 of the base 2; the nut 5 is sleeved on the top of the screw 4. Specifically, a spring washer is provided between the nut 5 and the top pressure plate 3 .

[0031] In the actual positioning processing process, compared with the traditional vise method, the processing positioning device can use the positioning square table and the positioning seat to clamp up and down to reliably fix the special-shaped thin-walled four-way frame. It not only solves the technical problem that the product processing process is very easy to deform, but also effectively improves the rigidity of the product during processing, avoids the flare of the four-way column during cutting, and effectively ensures that the corresponding screw holes are in the same plane.

[0032] In actual application, the base 2 uses four positioning bosses 205 as positioning references, the square platform 201 under the positioning bosses 205 is the cutting empty knife part, the top square plane of the square platform 201 is the calibration reference plane when the tooling is used, the outer diameter of the disc 202 is the clamping and pressing part of the tooling, and the center is an M12 threaded hole for the installation of the screw. The positioning square platform 301 of the top pressure plate 3 is placed in the square groove on the product, the screw 3 is used to connect the pressure plate 3, the base 2 and the four-way frame 1, and the nut is used for connection and tightening.

[0033] The technical effects of using this tooling are as follows:

[0034] The inner and outer shapes of the four-way frame can be completed by clamping at one time, thus improving production efficiency; solving the problem of difficult or impossible clamping; using this tooling, the processing strength of the product is increased, thus avoiding the consequences of product deformation or the formation of a bell-mouth; this tooling adopts four-hole positioning, and its position does not change after processing the four-way frame, thus meeting the requirements; since it is clamped at one time, each threaded hole is completed synchronously, and the corresponding screw holes in the four directions are kept in the same plane, and the error meets the requirements; using this tooling, the cutting strength is increased, thus greatly avoiding cutting vibration and improving product roughness; thus not only improving production efficiency but also ensuring product quality.
