Abstract

The utility model discloses a motorcycle drum brake bearing hole dual-head lathe processing device, which can make the cutting tools at two ends of the lathe feed tool and process motorcycle drum brake bearing dual-hole simultaneously which can ensure processing quality as well. The utility model consists of a dual-head lathe, workpiece and a fixture for arranging the workpiece and the fixture is fixed on the dual-head lathe. Compared with the existing technology, the utility model achieves processing the two bearing holes by one time; the coaxiality of the two bearing holes is good, the precision is high; the processing speed is rapid and is especially applicable to process pre-and-post drums bearing hole of motorcycle drum brake.

Description

Motor bike drum brake mechanism bearing hole double end turning lathe processing unit (plant)

One, technical field

The utility model relates to a kind of processing unit (plant), specifically a kind of motor bike drum brake mechanism bearing hole double end turning lathe processing unit (plant).

Two, background technology

Motor bike is a kind of important vehicle, and wherein the drg quality quality of motor bike is directly connected to people's life security.The processing of drg front and back drum bearing hole is especially crucial, and it requires two bearings hole right alignment 0.005, and the jerk value of the actual axial line in drum circle and two holes is not more than 0.10.Existing drg bearing hole is adding man-hour, at first with drum delineation position, process a stomidium, and then with this another stomidium of location, hole processing, its shortcoming is: 1, because the two bearings hole is not disposable machining, thereby two bearings hole right alignment is poor, can not meet the demands, and the drum circle can not guarantee drg rotating effect and poor stop with the jerk value of the actual axial line in two bearings hole; 2, add method of operation complexity in man-hour, make difficulty; 3, inefficiency adds and needs shutdown operation man-hour, changes the workpiece direction.

Three, summary of the invention

Goal of the invention of the present utility model provides a kind ofly can process motor bike drum brake mechanism bearing diplopore simultaneously, and guarantees the motor bike drum brake mechanism bearing hole double end turning lathe processing unit (plant) of crudy.

Goal of the invention of the present utility model is achieved like this: a kind of motor bike drum brake mechanism bearing hole double end turning lathe processing unit (plant), comprise double end turning lathe, workpiece and be used for installing the anchor clamps of workpiece, it is characterized in that: described anchor clamps are by being fixed on fixture mount on the double end turning lathe, having the clamp body of workpiece installation slot and the binding clasp of mounting groove degree of tightness is constituted; Clamp body is fixed on the fixture mount.

Impaired and mobile in the course of processing for preventing workpiece, on the inwall of clamp body mounting groove, be provided with the anchor clamps core.

For making things convenient for the placement of workpiece, be convenient to make and operation, described binding clasp comprises handle, clamp nut and bearing, and handle is fixed on the clamp nut, rotation by bearing when handle is in diverse location makes the mounting groove degree of tightness, thereby makes things convenient for the processing and the placement of workpiece.

Compared with prior art, the utility model can adopt two cutter feed simultaneously processing, can not shut down and finish workpiece processing, its advantage is: 1, because the two bearings hole is disposable machining, thereby two bearings hole right alignment is good, can meet the demands, and the jerk value of the actual axial line in drum circle and two bearings hole also can guarantee drg rotating effect and good braking performance and good; 2, it is simple, easy to manufacture to add the man-hour method of operation; 3, speed is fast, high efficiency.

Four, description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is a drum workpiece scheme drawing before and after the motor bike drum brake mechanism described in the utility model.

Five, the specific embodiment

Drum bearing hole double end turning lathe processing unit (plant) before and after a kind of motor bike drum brake mechanism described in the utility model, the double end turning lathe 1 of west, Henan machine tool works production has left knife bar cutter 11 and right knife bar cutter 12, drum workpiece 2 is installed in the anchor clamps 3 before and after the motor bike drum brake mechanism, and anchor clamps 3 are by being fixed on fixture mount 4 on the double end turning lathe 1, having the clamp body 5 of workpiece installation slot and the binding clasp 6 of mounting groove degree of tightness is constituted; Clamp body 5 is fixed on the fixture mount 4.Impaired and mobile in the course of processing for preventing workpiece 2, on the inwall of clamp body 5 mounting grooves, be provided with anchor clamps core 7.Binding clasp 6 comprises handle 8, clamp nut 9 and bearing 10, and handle 8 is fixed on the clamp nut 9.

Add man-hour, the operative employee spurs handle 8, rotation by bearing 10 makes clamp body 5 produce expansion, mounting groove unclamps, thereby drum workpiece 2 before and after the motor bike drum brake mechanism is put into, retract handle 8 again, workpiece 2 is clamped, adjust the left knife bar cutter 11 and the right knife bar cutter 12 of double end turning lathe 1, Φ 110 is a benchmark with the drum circle, start double end turning lathe 1, two hole Φ 37 are processed in cutter feed simultaneously in two, also can add a cutter on knife bar, process end face N simultaneously, make before and after the motor bike drum brake mechanism drum bearing hole is disposable to machine, can guarantee two bearings hole right alignment 0.005 like this, the drum circle is not more than 0.10 with the jerk value of the actual axial line in two holes.After machining, spur handle 8 again, make clamp body 5 produce expansion, take out workpiece 2.By measuring, rouse the right alignment 0.005 of two bearings hole Φ 37 before and after the motor bike drum brake mechanism, the jerk value of the actual axial line in drum circle Φ 110 and two holes is not more than 0.10.
