[0023] 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 ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A grinding machine fixture comprises a bearing platform 1 for bearing a mold base, positioning plates 2 which can move towards each other are arranged on both sides of the bearing platform 1, four sliding slots 3 in a circular array are opened on the bearing platform 1, and a horizontal guide plate 4 and a rotatable support ring 5 are arranged below the bearing platform 1.

[0025] Two sliding blocks 6 are slidably connected to the horizontal guide plate 4, the top of the sliding block 6 is fixedly connected with a sliding link 7, the top of the sliding link 7 is fixedly connected to the positioning plate 2, and is used to drive the positioning plate 2 to move together, the top of the support ring 5 is fixedly connected with an electric telescopic rod 8, the top of the electric telescopic rod 8 is fixedly connected with a lifting block 9, the two sides of the lifting block 9 are rotatably connected with a driving link 10, and one end of the driving link 10 is rotatably connected to the sliding block 6.

[0026] like Figure 1 , Figure 2 and Figure 3 The two positioning plates 2 are symmetrically arranged on both sides of the supporting platform 1, and can rotate on the outside of the supporting platform 1, and can also move in the direction of approaching or moving away from each other. The horizontal guide plate 4 passes through the sliding block 6, so that the sliding block 6 can only move horizontally on the horizontal guide plate 4. The two sliding blocks 6 are fixedly connected to the positioning plates 2 by sliding connecting rods 7, and the two positioning plates 2 are arranged in parallel.

[0027] The driving connecting rod 10 is provided with a movable notch 11 , and the top of the support ring 5 is fixedly connected with a support shaft 12 . The top of the support shaft 12 passes through the movable notch 11 and is fixedly connected to the horizontal guide plate 4 , so as to provide support for the horizontal guide plate 4 .

[0028] like Figure 2 and Figure 3The support shaft 12 passes through the movable slot 11 without affecting the rotation of the driving connecting rod 10 , and at the same time, the support shaft 12 connects the support ring 5 and the horizontal guide plate 4 .

[0029] The two ends of the horizontal guide plate 4 are fixedly connected to the limiting members 13 , and the sliding connecting rod 7 and the sliding notch 3 are adapted to each other.

[0030] like Figure 1 , Figure 2 and Figure 3 The limiter 13 can limit the sliding distance of the sliding block 6 so that the sliding block 6 cannot be separated from the horizontal guide plate 4. When the sliding block 6 slides, the sliding link 7 can slide along the direction of the sliding slot 3.

[0031] A support base 14 is provided at the bottom of the support ring 5, and a support plate 15 is fixedly connected to the support base 14. The top of the support plate 15 is rotatably connected to the bottom of the support ring 5. A servo motor 16 is fixedly installed on the support base 14, and the top of the servo motor 16 is fixedly connected to the support ring 5 for driving the support ring 5 to rotate.

[0032] like Figure 2 and Figure 3 The support plate 15 is connected to the support ring 5 through a tubular structure, so that the main shaft part of the servo motor 16 can pass through the tubular structure of the support plate 15 and connect with the support ring 5, driving the support ring 5 to rotate. The servo motor 16 can rotate forward and backward, and the angle of each rotation is 90°.

[0033] The support plate 15 is fixedly connected with a support rod 17 , and the top of the support rod 17 is fixedly connected to the bearing platform 1 to provide support for the bearing platform 1 .

[0034] like Figure 2 and Figure 4 The carrying platform 1 is fixed on the supporting plate 15 through the supporting rod 17 .

[0035] A groove is formed on one side of the positioning platen 2 close to the supporting platform 1 , so as to form a gradient on the positioning platen 2 .

[0036] like Figure 1 and Figure 3 Two square mold bases stacked up and down are arranged on the supporting platform 1, and a gradient is formed on the positioning platen 2 by using the groove, so that when the two positioning platens 2 are close to each other, the two mold bases stacked up and down can be squeezed and positioned at the same time, so that the two mold bases can be quickly positioned and aligned together.

[0037] The working principle of a grinder fixture provided by the utility model is as follows:

[0038] When the mold base on the carrier platform 1 needs to be positioned, the electric telescopic rod 8 is first retracted to drive the lifting block 9 to move downward. The lifting block 9 moves downward to pull the two sliding blocks 6 in the direction of approaching each other through the driving connecting rod 10. The sliding block 6 drives the two positioning pressing plates 2 to approach each other through the sliding connecting rod 7, so as to position the mold base from both sides. The sliding connecting rod 7 moves along the direction of the sliding notch 3.

[0039] Then the electric telescopic rod 8 extends and pushes the lifting block 9 upward, and the lifting block 9 moves upward and pushes the two sliding blocks 6 through the driving connecting rod 10, and the two sliding blocks 6 drive the positioning pressing plates 2 to move away from each other through the sliding connecting rod 7;

[0040] Then the servo motor 16 can drive the support ring 5 to rotate 90° counterclockwise, and the support ring 5 drives the electric telescopic rod 8 and the lifting block 9 to rotate 90° counterclockwise. The support ring 5 drives the horizontal guide plate 4 to rotate 90° counterclockwise through the support shaft 12, and the two positioning pressing plates 2 rotate 90° counterclockwise accordingly. When the electric telescopic rod 8 contracts again, the two positioning pressing plates 2 approach each other and press the mold base from the other two sides;

[0041] After the mold base processing is completed, the electric telescopic rod 8 is extended to separate the two positioning pressure plates 2, and the servo motor 16 rotates 90° clockwise, and the electric telescopic rod 8, the horizontal guide plate 4 and the positioning pressure plate 2 also rotate 90° clockwise, so that the positioning pressure plate 2 is reset, which is convenient for the next positioning processing of the workpiece.

[0042] Compared with the related art, the grinder fixture provided by the utility model has the following beneficial effects:

[0043] The utility model brings two parallel positioning pressure plates 2 close to each other, squeezes and positions the mold base from both sides of the mold base, and then rotates the positioning pressure plate 2. The positioning pressure plate 2 can extrude and position the mold base from the other two sides, so that when the mold base is positioned, the mold base can be pushed from four directions, and the mold base can be quickly and accurately positioned at the corresponding position on the supporting platform 1. At the same time, the groove on the positioning pressure plate 2 is used to form a gradient on the positioning pressure plate 2, so that when the positioning pressure plate 2 squeezes the upper and lower layers of the mold base, the upper and lower layers of the mold base remain parallel, and the upper and lower layers of the mold base can be quickly positioned to the corresponding position for processing.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
