DETAILED DESCRIPTION

[0025] 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 of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 The utility model provides a positioning device for polishing a notebook shell, comprising a base 1 and a shell body 2, the shell body 2 is clamped on the surface of the base 1, and both sides of the base 1 are provided with an adjustment seat 3, and the surface of the adjustment seat 3 is provided with a clamping plate 5 movably provided through a clamping cylinder 4, and an auxiliary clamping mechanism is provided between the clamping plate 5 and the adjustment seat 3;

[0027] The auxiliary clamping mechanism includes a driving outer cylinder 6, a driving rod 7, a limiting plate 8, a traction plate 9 and a connecting arm 10. The driving outer cylinder 6 is rotatably arranged on the surface of the clamping plate 5. The driving rod 7 is fixedly arranged on the surface of the traction plate 9. One end of the traction plate 9 penetrates and is slidably arranged on the surfaces of the adjustment seat 3 and the clamping plate 5. Both ends of the connecting arm 10 are hinged between the clamping plate 5 and the adjustment seat 3 through a connecting seat 11. One of the connecting seats 11 penetrates the adjustment seat 3 and can slide on the surface of the adjustment plate. A connecting plate 12 is arranged at one end of the connecting seat 11 on the adjustment plate. The connecting plate 12 is attached to the surface of the adjustment seat 3. One end of the traction plate 9 penetrates the connecting plate 12.

[0028] The driving rod 7 is connected to the driving outer cylinder 6 via a traction structure, so as to drive the limiting plate 8 to rotate and then clamp and fix it from the inner wall of the outer shell body 2 .

[0029] Specifically, in the present solution, the shell body 2 is inverted so that its cavity faces downward. At this time, the shell body 2 can be pressed against the clamping plate 5 from the inner wall through the auxiliary clamping mechanism, thereby fixing the shell body 2. A rubber protective pad 18 is bonded to the surface of the limiting plate 8, and the rubber protective pad 18 is in direct contact with the inner wall of the shell body 2. This greatly reduces the friction between the limiting plate 8 and the shell body 2, thereby protecting the contact portion between the shell body 2 and the limiting plate 8.

[0030] It should be noted that, since the present solution drives the clamping cylinder 4 to move the clamping plate 5, it is not the clamping plate 5 but the auxiliary clamping mechanism that actually clamps and fixes the outer shell body 2. The outer shell body 2 needs to be completely placed between the two clamping plates 5 before it needs to be fixed by the auxiliary clamping mechanism. Moreover, when the outer shell body 2 is fixed and clamped, the clamping plate 5 needs to be moved away from the outer shell body 2 by the clamping cylinder 4 first. However, the moving distance does not need to be too large. It is only necessary to enable the limit plate 8 to rotate in the opposite direction to the maximum stroke.

[0031] The traction structure includes a protrusion 13 arranged on the top of the inner wall of the driving outer cylinder 6, and a traction groove 14 arranged on the top surface of the driving rod 7. The projection of the traction groove 14 on the end surface of the driving rod 7 is arc-shaped.

[0032] Specifically, when the splint 5 moves toward the direction close to the adjustment seat 3, the end of the connecting arm 10 connected to the splint 5 will continue to rotate under the pressure of the splint 5, and the other end of the connecting arm 10 will translate toward the direction close to the clamping cylinder 4 while rotating. At this time, the connecting arm 10 can drive the connecting plate 12 to move synchronously through the connecting seat 11, and then the connecting plate 12 drives the traction plate 9 to move synchronously. When moving, the traction plate 9 can drive the driving rod 7 to move synchronously, so that the driving rod 7 drives the protrusion 13 to move. The protrusion 13 always remains in a horizontal state when moving. Therefore, the protrusion 13 can drive the driving rod 7 to rotate through the traction groove 14, so that the driving rod 7 drives the limit plate 8 to rotate and contact with the outer shell body 2, thereby clamping and fixing the outer shell body 2.

[0033] A guide portion 19 is integrally formed on the inner wall of the adjustment seat 3 , and a groove 20 matching the guide portion 19 is provided on the surface of the traction plate 9 , and the guide portion 19 is cooperatively connected with the groove 20 .

[0034] Specifically, when the splint 5 moves, the relative position of one end of the traction plate 9 and the splint 5 needs to remain unchanged through the cooperation of the guide portion 19 and the groove 20, and when the traction plate 9 slides horizontally, it can be limited by the cooperation of the guide portion 19 and the groove 20, thereby ensuring that there is no jamming between the drive rod 7 and the drive outer cylinder 6.

[0035] Torsion springs are installed at the connection points between the two ends of the connecting arm 10 and the connecting seat 11.

[0036] For the connecting arm 10 , the connecting arm 10 can deform and store energy when rotating at the connecting seat 11 , so that the torsion spring can buffer the movement of the clamping plate 5 through its own elastic force when the clamping cylinder 4 drives the clamping plate 5 to move.

[0037] In this embodiment, since the moving distance of the two clamps 5 is very short and it is difficult to adapt to the shell bodies 2 of different sizes, a size adjustment mechanism is set between the adjustment seat 3 and the base 1, and the size adjustment mechanism includes a screw 15, a knob 16 and a guide rod 17. The guide rod 17 is fixed to the surface of the adjustment seat 3, the screw 15 is rotatably set on the surface of the adjustment seat 3, the knob 16 is fixed to the surface of the screw 15, one end of the screw 15 is threadedly connected to the side of the base 1, and the guide rod 17 is slidably set on the side of the base 1.

[0038] Specifically, the screw 15 can be driven by rotating the knob 16. When rotating, the screw 15 can translate horizontally on the side of the base 1, so that the distance between the base 1 and the adjustment seat 3 can be changed, that is, the distance between the two splints 5 can be adjusted in the initial state to adapt to the shell body 2 of different sizes.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
