Embodiment 1

[0034] Embodiment 1. First, put the round mouth of the lathe fork 1 on the round mouth fixing cylinder 3, and then clamp the ring mouth on the ring mouth positioning pin 7. After the lathe fork is initially fixed, put the cross key rocker 2 The front cross key 20 is inserted into the cross lock 8 at the front end of the movable screw 5, and then the cross key rocker 2 is turned by hand to make the movable screw 5 rotate into the round mouth fixed cylinder 3, and the movable screw 5 moves into the round mouth fixed cylinder 3 for a while Touch the ball post 42 holding the fixed claw 4, and by pushing the ball post 42, the claw buckle 40 holding the fixed claw 4 will be lifted up, and it will be pushed against the round mouth of the lathe fork 1 to realize the fixation of the lathe fork 1 and clamping.

Embodiment 2

[0035] Embodiment 2. Since the fixing bolt 12 is threadedly connected with the ring opening positioning pin 7 through the bolt through groove 11, the ring opening positioning pin 7 can be fine-tuned on the middle plate 10 through the fixing bolt 12, so it can be better started. Due to the function of fixing the fork 1 of the lathe, the rotating shaft 41 of the clamping and fixing claw 4 is rotationally connected with the cylinder wall of the round mouth fixing cylinder 3. Therefore, after the ball post 42 is pushed, the clamping and fixing claw 4 will be centered on the rotating shaft 41. Rotation, clamping and fixing claw 4 rotations can make claw button 40 turn out from the claw button groove 30, thereby play fixing and clamping effect, abutment 6 bottom end is provided with leg to facilitate the movement and placement of abutment 6.

[0036] Based on the above, the present invention is simple in structure and flexible in use. The initial fixation of the lathe shift fork is r...

Abstract

The invention discloses a fork pulling processing fixture of a hand-rocking lathe, include an abutment portion, A drive portion and a clamping portion, A base portion includes a jig base and an intermediate plate, the clamping portion is located on the outside of the abutment, The clamping part comprises a round-mouth fixing cylinder, clamping fixing jaws, ring-mouth positioning pins and fixing pins, and the driving part comprises a cross key rocker and a movable screw rod. The invention improves labor productivity, ensures processing quality, reduces labor intensity, saves tedious working procedures in processing and has relatively low technical level requirements for workers.

Description

technical field [0001] The invention relates to the field of part processing, in particular to a processing jig for a fork of a hand-operated lathe. Background technique [0002] Lathe fork parts, located inside the lathe gearbox. The main function is to be used for the gear shifting of the lathe, so that the rotary motion of the spindle can work according to the requirements of the worker to obtain the required speed and torque. The upper hole in the part is connected to the operating mechanism, and the lower half hole is used to make contact with the shaft on which the controlled gear is located. The lower gear is shifted by the upper force. The two parts are cast as one piece and separated during machining. [0003] The disadvantages of the prior art are low production efficiency, lack of professional lathe shift fork clamps, and common clamps are difficult to achieve fast clamping and pick-up. In order to improve labor productivity, ensure processing quality, and red...
