[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figs. 1 to 3As shown, a vertical machining fixture for an explosion-proof motor base includes a worktable 1, a base plate 2 fixedly connected to the worktable 1, a servo rotary table 3 on the base plate 2, a fixture fixing seat 4 installed at the output end of the servo rotary table 3, a stepped fixture 5 fixedly connected to the fixture fixing seat 4, a crossbeam 6 above the base plate 2, two flanges 7 fixedly connected to the base plate 2, a fixing rod 8 fixedly connected inside the flange 7, one end of the crossbeam 6 is rotatably connected to one of the fixing rods 8 via a bearing, and one end of the crossbeam 6 is provided with a slot 61 for clamping the other fixing rod 8, a pneumatic-hydraulic booster cylinder 9 fixedly connected to the crossbeam 6, a fixing plate 10 fixedly connected to the output end of the pneumatic-hydraulic booster cylinder 9, a pressure plate 11 rotatably connected to the bottom of the fixing plate 10 via a slewing bearing, and a limit device 12 fixedly connected to the base 2 for calibration and limiting of the machine base 17.

[0023] In this embodiment, two guide posts 13 are fixedly connected to the fixing plate 10, and the guide posts 13 are slidably connected to the guide sleeves 14 on the crossbeam 6.

[0024] In this embodiment, the bottom of the clamping plate 11 is a conical surface that is larger at the top and smaller at the bottom. Both the clamping plate 11 and the stepped diaphragm 5 are provided with notches 15 that correspond to the flange connecting nut block 171 of the machine base 17. The notches 15 can be aligned with the flange connecting nut block 171, making it convenient for the drilling equipment to drill holes in the flange connecting nut block 171 from the notches 15.

[0025] In this embodiment, a locking cylinder 16 is provided on the fixing plate 10, and a positioning pin is fixedly connected to the output shaft of the locking cylinder 16. The pressing plate 11 is provided with a plurality of positioning holes 111 corresponding to the positioning pin. The positioning pin is inserted into the positioning hole 111, so that the pressing plate 11 cannot rotate, ensuring that the pressing plate 11 and the notch 15 of the stepped tire film 5 can always be aligned.

[0026] In this embodiment, the limiting device 12 includes a bracket 121, and a connecting rod 122 is rotatably connected to the top of the bracket 121. The connecting rod 122 rests against the base 172 of the machine base 17 and is used to correct the machine base 17 so that the base 172 faces the operator, making it easier to determine the drilling position.

[0027] Working process and its principle:

[0028] In the initial state, the notch 15 of the stepped membrane 5 is positioned such that when the base 17 foot 172 faces the operator, the notch 15 can be aligned with the flange connecting nut block 171. Meanwhile, the output shaft of the locking cylinder 16 is in the extended state, and the locating pin is located in the locating hole 111. At this time, the notch 15 of the pressure plate 11 is also aligned with the notch 15 of the stepped membrane 5.

[0029] When using this device, first rotate the crossbeam 6 to open it, so that the fixing rod 8 at one end disengages from the slot 61. At this time, rotate the crossbeam 6 to a position that does not affect the installation of the base 17. Then, place the base 17 on the stepped membrane 5. The stepped membrane 5 has different diameters for different stepped layers to accommodate bases of multiple diameters.

[0030] After the base 17 is placed on the stepped diaphragm 5, rotate the connecting rod frame 122. When the connecting rod frame 122 contacts the base 17, adjust the base 17 so that the bottom corner of the base 17 fits with the connecting rod frame 122, thus achieving the purpose of the base 17's bottom feet 172 facing the operator.

[0031] Then, the crossbeam 6 is rotated back to its original position, so that the slot 61 re-engages the column fixing rod 8. At this time, the clamping plate 11 is directly above the base 17. The pneumatic-hydraulic booster cylinder 9 is activated, causing its output shaft to extend and the clamping plate 11 to move down, pressing the base 17 onto the stepped diaphragm 5. This achieves the fixation of the base 17.

[0032] After the base 17 is fixed, rotate the connecting rod frame 122 in the opposite direction to disengage the connecting rod frame 122 from the base foot 172 of the base 17, so as to avoid affecting the normal processing of the base 17.

[0033] The output shaft of the locking cylinder 16 rises, the positioning pin is pulled out from the positioning block, the servo rotary table 3 adjusts the position of the base, and then the flange nut connecting block is drilled using a 90-degree drilling head.

[0034] After one hole is machined, the servo rotary table 3 rotates at a certain angle, which is the included angle between the positioning holes 111 on the two adjacent flange nut connecting blocks. The rotation of the servo rotary table 3 drives the stepped diaphragm 5 to rotate, and the stepped diaphragm 5 drives the machine base 17 and the clamping plate 11 to rotate together, so as to realize the machining of subsequent holes.

[0035] After all holes are machined, the locating pin is reinserted into the locating hole 111 to prevent the clamping plate 11 and the stepped diaphragm 5 from rotating relative to each other when the machine base 17 is removed, which would cause the notch 15 to misalign.

[0036] Finally, the clamping plate 11 rises, the crossbeam 6 is manually rotated, and the machine base 17 is removed, so that the remaining machine bases 17 can be processed.

[0037] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
