Technical field
The utility model relates to a kind of parts of broaching machine, relates in particular to a kind of automatic loading and unloading mechanism of workpiece broaching processing.
Background technology
What present air-conditioning cross valve workpiece inner plane processing was adopted is broaching processing, and by artificial loading and unloading, this mode of production has the following disadvantages:
1, the operative employee need constantly carry out loading and unloading, and labour intensity is bigger;
2, the proficiency to the operative employee requires high.
The utility model content
The utility model provides a kind of and is installed on the broaching machine in order to solve defective and the deficiency that above-mentioned prior art exists, and can realize automated production, improves broaching machine production efficiency, and the automatic loading and unloading mechanism of workpiece simple to operate, easy to maintenance broaching processing.
The technical solution of the utility model: a kind of automatic loading and unloading mechanism of workpiece broaching processing, comprise base and material feeding seat, described base is provided with guideway, described material feeding seat is arranged on the guideway, described base one side is provided with A drive unit and B drive unit from bottom to top successively, described A drive unit is connected with material feeding seat, also is provided with workpiece positioning seat, guide pillar, back-moving spring and C drive unit on the described material feeding seat.
Preferably, the quantity of described guideway is two, and the guide rail of two guideways is installed on the base, and described material feeding seat is installed on the slide block of guideway.
Preferably, described B drive unit is the pivot angle device, and its oscillation center is consistent with workpiece centre.
Preferably, the quantity of described guide pillar is two, and the quantity of described back-moving spring is two.
Preferably, the height of the height of described B drive unit and broaching machine upper guide bush and broaching tool matches.
The beneficial effects of the utility model: adopt automatic loading and unloading mechanism of the present utility model, make broaching machine be applicable to working continuously of workpiece in enormous quantities, can realize automated production, simple to operate, easy to maintenance, the production efficiency height.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
As Figure 1-3, a kind of automatic loading and unloading mechanism of workpiece broaching processing, comprise base 9 and material feeding seat 5, base 9 is provided with two guideways 6, material feeding seat 5 is arranged on the guideway 6, base 9 one sides are provided with A drive unit 8 and B drive unit 1 from bottom to top successively, and A drive unit 8 is connected with material feeding seat 5, and the height of the height of B drive unit 1 and broaching machine upper guide bush 10 and broaching tool 11 matches.The guide rail that also is provided with workpiece positioning seat 3, two guide pillars 4, two back-moving springs 7 and 2, two guideways 6 of C drive unit on the material feeding seat 5 is installed on the base 9, and material feeding seat 5 is installed on the slide block of guideway 6.B drive unit 1 is the pivot angle device, and its oscillation center is consistent with workpiece centre.
Operation principle of the present utility model:
After workpiece was placed on the workpiece positioning seat 3, B drive unit 1 stretched out forward, and pivot angle is 90 ° simultaneously, and workpiece is just put; C drive unit 2 stretches out, the gap that makes workpiece positioning seat 3 and material feeding seat 5 keep 1mm, and A drive unit 1 is sent workpiece into broaching tool 11, before workpiece entered guide pin bushing 10,2 withdrawals of C drive unit were under the effect of back-moving spring 7, workpiece positioning seat 3 touch with material feeding seat 5 to the whereabouts; A drive unit 8 continues workpiece is sent into guide pin bushing 10.After broaching was finished, A drive unit 1 was taken back workpiece, and C drive unit 1 stretches out when leaving guide pin bushing 10, makes workpiece positioning seat 3 pop up 1mm; After A drive unit 8 returns put in place, 90 ° of B drive unit 1 reverse pivot angles fell workpiece, and toward retraction, after action was finished, the upper and lower material action of workpiece was finished.
Automatic loading and unloading mechanism of the present utility model has substituted artificial loading and unloading, has alleviated operator's labour intensity, realizes automated production, has improved productivity ratio.
Above-described only is preferred embodiment of the present utility model; should be understood that; for those of ordinary skill in the art; under the prerequisite that does not break away from core technology feature of the present invention; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
