[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] like Figure 1 and Figure 2 As shown, a gear shaft end double-sided grinding and alignment device includes: a base 20, the base 20 having a rectangular platform, and a support leg installed at the bottom of the base 20;

[0029] The grinding frame 21 is U-shaped. Grinding heads 22 are symmetrically installed in the opening of the grinding frame 21. A motor for controlling the grinding heads 22 is installed on the wall of the grinding frame 21. The motor is electrically connected to the power supply. This is existing technology and will not be described in detail here.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping structure can fix the gear on the top of the base 20. The clamping structure includes: an adjustment frame 33, a base 36 and a clamp 38. The adjustment frames 33 are symmetrically arranged on the top of the base 20. The base 36 is movably arranged on the top of each adjustment frame 33. The clamp 38 is respectively arranged on the top of each adjustment frame 33. The base 36 and the clamp 38 can fix the gear.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the adjustment frame 33 is an inverted L-shaped plate, the base 36 is an upward-opening U-shaped rod, the clamp 38 is composed of a disc and a bottom tube, and the clamping structure also includes a fixed frame 30, a servo motor 31, a control shaft 32, a rotating groove 34, a rotating component 35, and a screw 37. The fixed frames 30 are symmetrically fixedly connected to the top two sides of the base 20, the servo motor 31 is fixedly connected to the side wall of one of the fixed frames 30, the control shaft 32 is rotatably connected between the symmetrical fixed frames 30, and the symmetrical adjustment frames 33 can be threadedly connected to the wall surface of the control shaft 32. The rotating groove 34 is formed in each adjustment frame 30. At the top of 3, the rotating part 35 is fixedly connected to the bottom of each base 36, the screw 37 is fixedly connected to the bottom of each press 38, the frame 30 is an L-shaped plate, the servo motor 31 can drive the control shaft 32 to rotate, the control shaft 32 is a worm with opposing threads on the wall, the bottom of the adjustment frame 33 on each side can fit against the wall of the frame 30, the rotating part 35 is composed of an upper cylindrical part and a bottom disc, the rotating groove 34 can adapt to the cylindrical rotation of the rotating part 35, the top of the adjustment frame 33 is also provided with a threaded groove, and the screw 37 can pass through the threaded groove at the top of the adjustment frame 33;

[0032] In practical use, the spacing of the symmetrical adjustment frame 33 is first adjusted by the servo motor 31. The servo motor 31 can drive the control shaft 32 to rotate when the power is turned on. When the control shaft 32 rotates, it can drive the symmetrical adjustment frame 33 to move through the thread on its wall. After the adjustment is completed, the gear on the end wall of the gear shaft to be ground is placed flat on the top of the symmetrical base 36. Then, by controlling the rotation of each side pressure 38, the pressure 38 is moved downward to press the gear. At this time, the upper and lower shaft ends of the gear will be in a vertical state. Then, by turning on the motor on the wall of the grinding frame 21, the grinding head 22 can be controlled to simultaneously grind the upper and lower shaft ends of the gear. During grinding, the gear teeth will not contact any structure. After grinding is completed, the gear position can be unlocked by rotating the pressure 38. The base 36 can rotate automatically on the top of the adjustment frame 33. The base 36 can be further adapted to the wall below the gear by rotating the base 36.

[0033] In summary, by setting up a clamping structure to fix the gear by clamping it from the top and bottom on each side, the problem of accidentally damaging the gear teeth during grinding can also be prevented.

[0034] like Figure 1 and Figure 2As shown, a material collection structure is provided on the top of the base 20. The material collection structure includes a guide plate 23 and an adsorption rod 24. The guide plate 23 is symmetrically fixedly connected to the top of the base 20, and the adsorption rod 24 is fixedly connected to the bottom of the base 20. A rectangular groove is opened through the top of the base 20. The guide plate 23 is a rectangular plate and is obliquely placed in the rectangular groove on the wall of the base 20. The symmetrical guide plates 23 have a spacing. The adsorption rod 24 is an upward-opening U-shaped rod and is located directly below the spacing of the symmetrical guide plates 23. The adsorption rod 24 is made of magnetic material.

[0035] In practical use, when grinding is performed at the end of the gear shaft, the falling steel chips will gather towards the center along the symmetrical guide plate 23, and then move to the wall of the adsorption rod 24 and finally be adsorbed by the adsorption rod 24.

[0036] In summary, by setting up a material collection structure, the steel chips are guided by the guide plate 23 and adsorbed by the adsorption rod 24, so as to collect the steel chips that fall during grinding. This makes it easier for workers to collect the steel chips and reduces the loss during grinding.

[0037] Working principle: First, the spacing of the symmetrical adjustment frame 33 is adjusted by the servo motor 31. When the power is turned on, the servo motor 31 can drive the control shaft 32 to rotate. When the control shaft 32 rotates, it can drive the symmetrical adjustment frame 33 to move through the thread on its wall. After the adjustment is completed, the gear on the end wall of the gear shaft to be ground is placed flat on the top of the symmetrical base 36. Then, by controlling the rotation of the pressure 38 on each side, the pressure 38 is moved downward to press the gear. At this time, the upper and lower shaft ends of the gear will be in a vertical state. Then, by turning on the motor on the wall of the grinding frame 21, the grinding head 22 can be controlled to simultaneously grind the upper and lower shaft ends of the gear.
