[0002] The power output shaft of agricultural machinery is an important component of agricultural machinery. It is mainly used to connect with the driving parts and then output power. During the processing of the power output shaft of agricultural machinery, it is generally necessary to clamp it with a fixture and then use a tool for cutting.

[0003] However, the existing fixture is generally fixed on the workbench. After the output shaft is clamped and fixed, its position is inconvenient to move, and it is difficult to adjust the output shaft for processing at different positions. When it is necessary to process positions of different lengths on the output shaft, the output shaft needs to be removed and then re-clamped and fixed. The whole process is cumbersome and affects the processing efficiency.

[0004] Therefore, we propose a more practical tooling fixture for processing the power output shaft of agricultural machinery. Utility Model Content

[0007] Furthermore, a convex rail is connected to the upper surface of the base, and an arc groove matching the convex rail is opened on the lower surface of the support frame.

[0008] Furthermore, a plurality of mounting holes are symmetrically provided on two edges of the base.

[0009] Furthermore, one end of the screw passes through the side wall of the base and is connected to a hand crank.

[0010] Furthermore, a slide groove is opened inside the fixed plate, a double-headed screw is rotatably installed inside the slide groove, and a motor 2 for driving the double-headed screw to rotate is installed outside the fixed plate. A slider is connected to the side of the splint close to the fixed plate, and the double-headed screw passes through the slider and is threadedly connected to the slider.

[0011] Furthermore, the sliding block is slidably connected to the fixed plate via a sliding groove, and the sliding blocks are symmetrically distributed about the double-headed screw.

[0012] Furthermore, V-shaped grooves are symmetrically provided on opposite sides of the clamping plate.

[0013] Furthermore, a rotating drum is fixed to one side of the support frame close to the fixed plate, and a stabilizing cover is fixed to one side of the fixed plate close to the support frame. The stabilizing cover and the rotating drum are sleeved with each other, and a plurality of steel balls are embedded on the surface of the rotating drum so as to rotate in a circumferential direction.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The cam 3 is provided with a plurality of support plates 1 and a plurality of support plates 2, and the support plates 3 are provided with a plurality of support plates 1 and a plurality of support plates 3. The support plates 3 are provided with a plurality of support plates 1 and a plurality of support plates 3. The support plates 3 are provided with a plurality of support plates 1 and a plurality of support plates 3. The support plates 3 are provided with a plurality of support plates 1 and a plurality of support plates 3. The support plates 3 are provided with a plurality of support plates 1 and a plurality of support plates 3. The support plates 3 are provided with a plurality of support plates 1 and a plurality of support plates 3. The support plates 3 are provided with a plurality of support plates 1 and a plurality of support plates 3.

[0023] Taking into account that the support frame 3 may deflect when moving, a convex rail 52 is connected to the upper surface of the base 5, and an arc groove 31 matching the convex rail 52 is opened on the lower surface of the support frame 3, so that the convex rail 52 is embedded in the arc groove 31. When the support frame 3 moves, the convex rail 52 and the arc groove 31 are limited to maintain its stability during movement.

[0024] In order to facilitate the fixation of the base 5 and the workbench, a plurality of mounting holes 51 are symmetrically provided on the two edges of the base 5 so that bolts can be screwed into the mounting holes 51 to lock and install the base 5 with the workbench.

[0025] In order to conveniently control the rotation of the screw rod 6, one end of the screw rod 6 passes through the side wall of the base 5 and is connected to a hand crank handle 61. The hand crank handle 61 adopts an L-shaped structure, which is convenient for hand-held rotation.

[0026] In order to facilitate clamping and fixing the output shaft, a slide groove 11 is provided inside the fixing plate 1, and a double-headed screw 12 is rotatably installed inside the slide groove 11, and a motor 7 for driving the double-headed screw 12 to rotate is installed outside the fixing plate 1. A slider 21 is connected to the side of the clamping plate 2 close to the fixing plate 1, and the double-headed screw 12 passes through the slider 21 and is threadedly connected to the slider 21. The double-headed screw 12 has two thread segments with opposite thread directions, and the two sliders 21 are respectively connected to the two thread segments. The center point of the double-headed screw 12 coincides with the center point of the fixing plate 1, and the slider 21 is symmetrically distributed about the double-headed screw 12, so that when the double-headed screw 12 rotates, the two sliders 21 move closer to or away from each other under the limiting action of the slide groove 11 and the action of the thread, so as to clamp or loosen the output shaft and keep the output shaft always in the center position of the fixing plate 1 when clamped.

[0027] In order to improve the clamping degree of output shafts with different diameters, V-grooves are symmetrically provided on the opposite sides of the clamping plate 2. Then, by utilizing the V-groove structure, two sets of symmetrical clamping points are present between the output shaft and the two clamping plates 2 after the output shaft is clamped. This not only can adapt to the outer diameter of the output shaft, but also makes the clamping more secure.

[0028] In order to improve the stability of the fixed plate 1 when driving the output shaft to rotate, a rotating drum 9 is fixed on one side of the support frame 3 close to the fixed plate 1, and a stabilizing cover 8 is fixed on one side of the fixed plate 1 close to the support frame 3. The stabilizing cover 8 is sleeved on the outside of the rotating drum 9, and the outer wall of one end of the rotating drum 9 extending into the stabilizing cover 8 is inlaid with a plurality of steel balls 91 that rotate along the circumferential direction. The part of the steel balls 91 protruding from the rotating drum 9 fits with the stabilizing cover 8. Through the rotation of the steel balls 91, the stabilizing cover 8 can rotate stably outside the rotating drum 9, thereby assisting the rotation of the fixed plate 1 and maintaining the stability of the rotation of the fixed plate 1. In order to facilitate the assembly of the stabilizing cover 8 and the rotating drum 9, the stabilizing cover 8 and the fixed plate 1 are connected by a plurality of bolts, so that the stabilizing cover 8 is easy to disassemble relative to the fixed plate 1, and then the stabilizing cover 8 is convenient to be detached from the outside of the rotating drum 9.
