All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides the following technical solutions: a key pulling groove device convenient for depth adjustment comprises a processing table 1, wherein the top of the processing table 1 is fixedly connected with a fixed column 2, the output end of the fixed column 2 is fixedly connected with a transverse plate 3, the bottom of the transverse plate 3 is fixedly connected with a connecting plate 4, a transmission lead screw 5 is rotatably connected between the connecting plates 4 through a bearing, the surface of the transmission lead screw 5 is connected with a threaded seat 6 through threads, two sides of the threaded seat 6 are fixedly connected with connecting frames 7, one side of each connecting frame 7 is fixedly connected with an adjusting seat 8, the top of the adjusting seat 8 is connected with a threaded rod 9 through threads, one end of the threaded rod 9 is rotatably connected with a fixed tool rest 10 through a bearing, the other end of the threaded rod 9 is fixedly connected with a rotary table 11, the bottom of the fixed tool rest 10 is fixedly provided with a broach 12, the threaded rod 9 can be conveniently rotated through the rotation of the rotary table 11, and the broach 12 in the fixed tool rest 10 can be vertically adjusted, so as to complete the accurate control of the depth when the workpiece is subjected to key slot broaching, thereby greatly improving the working quality when the key slot is subjected to key slot broaching and enhancing the practicability.

Specifically, the top of the processing table 1 is fixedly connected with a fixed plate 13 and a limiting plate 16 respectively, one side of the fixed plate 13 is fixedly connected with a first electric control jack 14, the telescopic end of the first electric control jack 14 is fixedly connected with a movable plate 15, and the surfaces of the movable plate 15 and the limiting plate 16 are fixedly connected with rubber pads 17, so that the clamping and fixing can be adjusted in time according to the size of a workpiece.

Specifically, the surface of the moving plate 15 is fixedly connected with a guide rod 18, and the guide rod 18 is slidably connected with the inner wall of the fixed plate 13, so that the stability of the moving plate 15 during moving can be enhanced.

Specifically, the two sides of the adjusting seat 8 are fixedly connected with guide rails 19, the surface of the guide rails 19 is slidably connected with sliding blocks 20, and the sliding blocks 20 are fixedly connected with the two sides of the fixed tool rest 10, so that the fixed tool rest 10 can stably guide when descending, and the phenomenon of autorotation in the descending process of the fixed tool rest 10 is prevented.

Specifically, the scale code 21 has been seted up on the surface of adjusting seat 8, and the fixed surface of stationary knife rest 10 is connected with pointer 22, and pointer 22 is located the dead ahead of scale code 21, makes things convenient for the staff to look over the scale of going up and down to in more accurate control.

Specifically, one side fixedly connected with driving motor 23 of connecting plate 4, driving motor 23's output passes through shaft coupling fixed connection transmission lead screw 5, is convenient for can provide the power take off source for transmission lead screw 5.

Specifically, the threaded seat 6 is connected with the rotary table 11 through a second electric control jack 24; the fixed end of the second electric control jack 24 is fixed with the threaded seat 6, and the telescopic end of the second electric control jack 24 is rotatably connected with the rotary table 11 through a bearing. Because the broach 12 can bear a large pressure when performing the key slot broaching process, the broach 12 is limited to be forced to retract only by the friction force between the threaded rod 9 and the adjusting seat 8, on one hand, threads on the matched threaded grooves in the threaded rod 9 and the adjusting seat 8 are large in pressure abrasion, and on the other hand, the problem of forced retraction of the broach 12 is difficult to limit. And the relative position of the threaded rod 9 can be effectively solved by controlling the relative position of the threaded rod by the second electric control jack 24. At this time, when the position of the broach 12 needs to be adjusted, the telescopic end of the second electric control jack 24 is made to perform telescopic motion by sending a control command, so that the rotary table 11 drives the threaded rod 9 to rotate upwards or downwards, and the broach 12 is driven to move upwards and downwards. During operation, the stress born by the broach 12 is born by the threaded rod 9 and the thread on the thread groove matched in the adjusting seat 8 on the one hand, and is born by the second electric control jack 24 on the other hand, and the stress can reduce the degree of the thread stress abrasion on the thread groove matched in the threaded rod 9 and the adjusting seat 8 through the stress, and effectively prevent the stress of the broach 12 from retracting, and ensure that the depth of the pulled key groove is consistent.

The working principle of the utility model is as follows: when the key groove is pulled, firstly, a worker pulls the key groove depth of the key groove according to the requirement of a workpiece, the rotary table 11 is rotated to drive the threaded rod 9 to rotate, and then the fixed knife rest 10 is driven to adjust the seat 8 to move up and down, so that the adjustment of the up-and-down position of the broach 12 fixed on the fixed knife rest 10 is realized. When the broach 12 is located at different upper and lower positions, the key grooves with different depths can be pulled out, and the operation is convenient.

When key groove drawing is performed, a workpiece is first placed on the top of the machining table 1 between the moving plate 15 and the stopper plate 16. And then the moving plate 15 is pushed to move by controlling the first electric control jack 14, so that the moving plate 15 and the limiting plate 16 can fasten the workpiece. This setting can be according to the effect size of a dimension of work piece and adjust the centre gripping to avoid because of the too big or too little problem that causes unable stable centre gripping of working dimension, and then guaranteed the work piece steadiness when acting as go-between, and then avoid because the keyway bending or the broach wearing and tearing that the work piece displacement leads to when acting as go-between. Through the setting of rubber pad 17, can play the effect of protection to the surface of work piece, avoid rigidity direct contact to cause the wearing and tearing phenomenon of processing man-hour. Then, the driving motor 23 drives the transmission screw rod 5 between the connecting plates 4 to rotate, so that the threaded seat 6 can be driven to move, the connecting frame 7 drives the adjusting seat 8 to move, and the broaching tool 12 is moved on a workpiece to complete broaching groove processing.
