DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings. Figures 1-5 The embodiments described are only possible technical implementations of the present application, and not all possible implementations. Those skilled in the art can easily obtain other embodiments by combining the embodiments of the present application without creative labor, and these embodiments are also within the protection scope of the present application. The present application mainly adopts the following one flange fork pull end tooth broaching machine, referring to Figure 1 , comprising a rack 1, a workbench 11 is arranged in the rack 1, a clamping piece 12 for positioning the flange fork is arranged on the workbench 11, a fixing frame 13 is arranged on the side of the workbench 11 away from the clamping piece 12, a fixing disc 14 is rotatably connected to the fixing frame 13, and a broach 15 is arranged on the fixing disc 14. The broach 15 works to pull end teeth on the end part of the flange fork.

[0013] Referring to Figure 2 and Figure 3 , the outer gear ring 141 is fixedly connected to the fixing disc 14, the power motor 142 is fixedly connected to the fixing frame 13, the output shaft of the power motor 142 is fixedly connected with the gear 143, and the gear 143 is engaged with the outer gear ring 141. When the power motor 142 is started, the gear 143 rotates to drive the outer gear ring 141 and the fixing disc 14 to rotate by 90 degrees.

[0014] Referring to Figure 4 and Figure 5 , the fixing disc 14 is connected with the bidirectional reciprocating screw 151, the driving motor 152, the positioning seat 153 and the guide sliding block 154. The bidirectional reciprocating screw 151 is rotatably connected to the fixing disc 14, the driving motor 152 is fixedly connected to the fixing disc 14, and the output shaft of the driving motor 152 is fixedly connected with the end part of the bidirectional reciprocating screw 151. The positioning seat 153 is threadedly connected to the bidirectional reciprocating screw 151, and the broach 15 is connected to the positioning seat 153. When the driving motor 152 is electrified, the bidirectional reciprocating screw 151 is driven to rotate, the positioning seat 153 drives the broach 15 to reciprocate along the axial direction of the bidirectional reciprocating screw 151, and the operation of the broach 15 to pull teeth of the flange fork is realized. In order to improve the stability of the positioning seat 153, the guide groove is formed in the fixing disc 14, and the guide sliding block 154 is slidably connected in the guide sliding groove 155.

[0015] The T-shaped sliding block 159 is fixedly connected to the two sides of the drawbar 15, and the drawbar 15 is connected with the positioning rods 158, and the T-shaped sliding grooves 1581 are formed in the positioning rods 158.
