Technical Field

[0001] The present application relates to the technical field of installation fixtures, and in particular to an overflow brick processing and installation fixture. Background Art

[0002] Overflow bricks are key components in the molding process of overflow down-draw production of glass substrates. Molten glass overflows from the groove of the overflow brick, passes through the surfaces on both sides of the overflow brick, and converges at the tip of the overflow brick to form a glass substrate. The material of the overflow brick has the characteristics of super-hard and brittle material, and the smoothness of the outer surface of the overflow brick is very high, so the processing accuracy of the overflow brick is extremely high.

[0003] A Chinese patent with publication number CN115446988A discloses a method for processing flexible glass overflow bricks, which discloses: placing the overflow brick blank on a horizontal positioning structure composed of pad bricks and wedge-shaped pad bricks, checking the straightness of the first step surface and the second step surface of the overflow brick, fixing it after adjustment, and using pad bricks and wedge-shaped pad bricks for positioning during fixing.

[0004] Overflow bricks need to be clamped and processed once during processing. However, in the related art, during the processing of overflow bricks, due to the lack of effective fixation, it is easy for the workpiece to move and offset the processing coordinates, resulting in quality problems in the processing of overflow bricks. Utility Model Content

[0005] In view of this, the present application provides an overflow brick processing and installation fixture to solve the problem that the workpiece is easily moved due to the lack of effective fixation during the overflow brick processing, resulting in uneven processing quality.

[0009] The sealing member is disposed in the negative pressure cavity in a surrounding manner, and the overflow brick is closely fitted to the sealing member when installed;

[0010] The negative pressure chamber is connected to an external negative pressure device.

[0011] In some embodiments, along the height direction, the upper surface of the reference bearing block is arranged higher than the upper surface of the base; and along the height direction, the upper surface of the sealing member is arranged higher than the upper surface of the reference bearing block.

[0012] In some embodiments, at least one negative pressure hole is provided in the area of ​​the base located in the negative pressure chamber, and a pump air port connected to an external negative pressure device is also provided on the side of the base; the pump air port is connected to the negative pressure hole.

[0013] In some embodiments, the first end dimension of the main body of the overflow brick along the length direction is smaller than the second end dimension;

[0014] The base matches the shape of the main body of the overflow brick, and the negative pressure cavity matches the shape of the base; along the length direction of the base, the negative pressure cavity is formed with a negative pressure cavity small end and a negative pressure cavity large end;

[0015] There are multiple negative pressure holes, and the size of the negative pressure hole close to the small end of the negative pressure cavity is smaller than the size of the negative pressure hole close to the large end of the negative pressure cavity.

[0016] In some embodiments, the base is formed with a base small end and a base large end along the length direction, and the reference bearing blocks arranged on both sides of the base along the length direction respectively match the shapes of the base small end and the base large end;

[0017] And the dimensions of the reference load-bearing blocks on both sides along the height direction are consistent.

[0018] In some embodiments, the base is configured as a trapezoid.

[0019] In some embodiments, the reference load-bearing blocks disposed on both sides of the base along the length direction are fixedly connected to the base via fixing members.

[0020] In some embodiments, the material of the reference load-bearing block is the same as that of the overflow brick, and the material of the reference load-bearing block includes zircon.

[0021] In some embodiments, the overflow brick includes a main body, and a guide portion disposed on one side of the main body, and a surface of the main body facing away from the guide portion is defined as a positioning inclined surface;

[0022] The overflow brick processing and installation fixture also includes: an abutting positioning piece, which abuts against the positioning inclined surface to make the overflow brick and the base relatively aligned.

[0023] In some embodiments, the number of the abutting positioning members is at least two, the positioning planes of at least two abutting positioning members are parallel, and the abutting positioning members are slidably connected to the base.

[0024] Through the above technical solution, the overflow brick processing and installation fixture provided by the present application has the following beneficial effects:

[0025] 1. The overflow brick processing and installation fixture provided in the embodiment of the present application has a local depression on the top surface of the base to form a negative pressure cavity, the negative pressure cavity is connected to the external negative pressure equipment, and the sealing member is arranged around the negative pressure cavity. The overflow brick fits tightly with the sealing member in the installed state, and can extract the air in the negative pressure cavity to achieve the effect of a suction cup, so that the overflow brick is fixed under the action of negative pressure, thereby playing a good fixing effect on the overflow brick, avoiding the overflow brick from moving or offsetting the processing coordinates, thereby ensuring the subsequent processing quality of the overflow brick, improving processing efficiency, reducing processing risks, improving the yield rate, and reducing the possibility of workpiece damage.

[0026] 2. By setting the upper surface of the reference bearing block higher than the upper surface of the base, the base can be prevented from being stressed, the overflow brick can be prevented from contacting the base over a large area, and the bumps or scratches on the overflow brick can be reduced. By setting the upper surface of the seal higher than the upper surface of the reference bearing block, the seal can be kept under pressure. When the overflow brick is placed on the reference bearing block, the seal is squeezed and deformed, thereby sealing the negative pressure cavity.

[0027] 3. By increasing the number of negative pressure holes and making the size of the negative pressure holes near the small end of the negative pressure chamber smaller than the size of the negative pressure holes near the large end of the negative pressure chamber, the number of negative pressure holes can be increased. When the bottom area of ​​the negative pressure chamber is small, the arrangement requirements of the negative pressure holes can be met, thereby improving the negative pressure adsorption effect.

[0028] 4. By making the material of the reference load-bearing block the same as that of the overflow brick, it can be ensured that it is not easy to bump into it during the lifting process, and at the same time avoid scratches on the surface of the overflow brick.

[0029] 5. By arranging an abutting positioning piece on the side of the base corresponding to the positioning inclined surface, the abutting positioning piece can abut against the positioning inclined surface to make the overflow brick relatively aligned with the base, so that when the overflow brick is hoisted to the overflow brick processing and installation fixture, it can be quickly aligned to improve assembly efficiency.

[0030] 6. By making the number of abutment positioning members at least two, it is possible to ensure multi-point alignment and improve the alignment accuracy between the overflow brick and the base. By making the abutment positioning member slidably connected to the base, on the one hand, after the overflow brick and the base are aligned, the sliding abutment positioning member can be used to verify the assembly position of the overflow brick, and on the other hand, it is convenient to replace abutment positioning members of different specifications and models.

[0045] Combine the following Figures 1 to 4 , describing an embodiment of the present application.

[0046] According to an embodiment of the present application, there is provided an overflow brick processing and installation fixture, comprising:

[0047] The base 2 matches the shape of the main body 41 of the overflow brick 4, and the top surface of the base 2 is partially concave to form a negative pressure cavity;

[0048] The reference bearing blocks 1 are arranged on both sides of the base 2 along the length direction, and the reference bearing blocks 1 are suitable for supporting the overflow bricks 4;

[0049] The sealing member 3 is disposed in the negative pressure cavity in a surrounding manner, and the overflow brick 4 is closely fitted to the sealing member 3 in the installed state;

[0050] The negative pressure chamber is connected to an external negative pressure device.

[0051] In order to facilitate understanding of the specific structural form of the overflow brick processing and installation fixture provided in the embodiment of the present application, the structural form of the overflow brick 4 is first described, and then the structure of the overflow brick 4 is described. Figure 3 As shown, the overflow brick 4 includes a main body 41, the outer surface of which is configured as a plane. By fitting one side of the outer surface of the main body 41 with the overflow brick processing and installation fixture provided in the embodiment of the present application, the overflow brick processing and installation fixture can realize negative pressure adsorption of the main body 41, so as to fix the overflow brick 4. The main body 41 of the overflow brick 4 has different dimensions along the length direction. In this embodiment, the main body 41 of the overflow brick 4 is configured as a trapezoid, and the first end dimension of the main body 41 along the length direction is smaller than the second end dimension. A guide portion 42 is formed on one side of the main body 41, and the cross section of the guide portion 42 is conical, so that the glass liquid flows down along the guide portion 42.

[0052] Correspondingly, the base 2 matches the shape of the main body 41 of the overflow brick 4, and a negative pressure cavity is formed by partially recessing the top surface of the base 2, that is, the surface of the base 2 on one side facing the main body 41 is partially recessed to form a negative pressure cavity, so that when the main body 41 of the overflow brick 4 is aligned with the base 2, the projection of the negative pressure cavity toward the main body 41 can be located within the range of the main body 41.

[0053] Since the overflow brick 4 weighs several tons, by arranging reference load-bearing blocks 1 on both sides of the base 2 along the length direction, the overflow brick 4 can be supported by the reference load-bearing blocks 1, so that the reference load-bearing blocks 1 bear the weight of the overflow brick and avoid crushing the seal 3.

[0054] The top surface of the base 2 is partially recessed to form a negative pressure cavity, and the negative pressure cavity is connected to an external negative pressure device, such as a vacuum pump or an air compressor. When the external negative pressure device is working, it can suck air outward, thereby extracting the air in the negative pressure cavity to achieve the effect of a suction cup, thereby achieving the suction of the overflow brick 4 under the action of negative pressure.

[0055] In order to improve the sealing effect and ensure good adsorption, the seal 3 is arranged around the negative pressure chamber so that the overflow brick 4 fits tightly with the seal 3 in the installed state, thereby ensuring the vacuum degree in the negative pressure chamber.

[0056] The overflow brick processing and installation fixture provided in the embodiment of the present application has a local depression on the top surface of the base 2 to form a negative pressure cavity, the negative pressure cavity is connected to the external negative pressure equipment, and the seal 3 is arranged around the negative pressure cavity. The overflow brick 4 is tightly fitted with the seal 3 in the installed state, and the air in the negative pressure cavity can be extracted to achieve the effect of a suction cup, so that the overflow brick 4 is fixed under the action of negative pressure, thereby playing a good fixing effect on the overflow brick 4, avoiding the overflow brick 4 from moving or offsetting the processing coordinates, thereby ensuring the subsequent processing quality of the overflow brick 4, improving processing efficiency, reducing processing risks, improving the yield rate, and reducing the possibility of workpiece damage.

[0057] In this embodiment, the upper surface of the reference load-bearing block 1 is parallel to the horizontal plane, thereby ensuring that the overflow brick 4 is adsorbed in a horizontal state.

[0058] In some embodiments, in combination Figure 1 As shown, along the height direction, the upper surface of the reference bearing block 1 is arranged higher than the upper surface of the base 2; and along the height direction, the upper surface of the sealing member 3 is arranged higher than the upper surface of the reference bearing block 1.

[0059] By setting the upper surface of the reference load-bearing block 1 higher than the upper surface of the base 2, it is possible to avoid stress on the base 2, avoid large-area contact between the overflow brick 4 and the base 2, and reduce bumps or scratches on the overflow brick 4.

[0060] By setting the upper surface of the seal 3 higher than the upper surface of the reference bearing block 1, it can be ensured that the seal 3 is in a pressurized state. When the overflow brick 4 is placed on the reference bearing block 1, the seal 3 is squeezed and deformed, thereby sealing the negative pressure cavity.

[0061] The sealing member 3 is made of a flexible material, specifically rubber or the like.

[0062] In some embodiments, in combination Figure 2 As shown, at least one negative pressure hole 21 is provided in the area of ​​the base 2 located in the negative pressure chamber, and a pump air port 22 connected to an external negative pressure device is also provided on the side of the base 2; the pump air port 22 is connected to the negative pressure hole 21.

[0063] The bottoms of the multiple negative pressure holes 21 are connected and ventilated together. After the pump air port 22 is connected to the external negative pressure device, the air in the negative pressure cavity can be pumped out through the negative pressure holes 21. The overflow brick processing and installation fixture realizes negative pressure adsorption of the main body 41, so as to fix the overflow brick 4.

[0064] In some embodiments, in combination Figure 2 , Figure 3 As shown, the first end dimension of the main body 41 of the overflow brick 4 along the length direction is smaller than the second end dimension;

[0065] The base 2 matches the shape of the main body 41 of the overflow brick 4, and the negative pressure cavity matches the shape of the base 2; along the length direction of the base 2, the negative pressure cavity is formed with a negative pressure cavity small end and a negative pressure cavity large end;

[0066] There are multiple negative pressure holes 21, and the size of the negative pressure hole 21 close to the small end of the negative pressure chamber is smaller than the size of the negative pressure hole 21 close to the large end of the negative pressure chamber.

[0067] As a variation, the sizes of the multiple negative pressure holes 21 are gradually increased to match the bottom area of ​​the negative pressure chamber.

[0068] By increasing the number of negative pressure holes 21 and making the size of the negative pressure holes 21 near the small end of the negative pressure chamber smaller than the size of the negative pressure holes 21 near the large end of the negative pressure chamber, the number of negative pressure holes 21 can be increased. When the bottom area of ​​the negative pressure chamber is small, the arrangement requirements of the negative pressure holes 21 can be met, thereby improving the negative pressure adsorption effect.

[0069] In some embodiments, in combination Figure 2 As shown, the base 2 is formed with a base small end and a base large end along the length direction, and the reference load-bearing blocks 1 arranged on both sides of the base 2 along the length direction respectively match the shapes of the base small end and the base large end;

[0070] Furthermore, the dimensions of the reference load-bearing blocks 1 on both sides along the height direction are consistent.

[0071] By matching the shapes of the reference bearing blocks 1 arranged on both sides of the base 2 along the length direction with the small end and the large end of the base respectively, the flatness of the base 2 and the reference bearing blocks 1 after assembly can be ensured to avoid scratching the overflow bricks 4.

[0072] At the same time, the dimensions of the reference load-bearing blocks 1 on both sides along the height direction are ensured to be consistent, so that the overflow bricks 4 can be kept horizontal and avoid tilting.

[0073] In some embodiments, in combination Figure 2 As shown, the base 2 is configured in a trapezoidal shape.

[0074] By configuring the base 2 to be trapezoidal, the base 2 can be matched with the shape of the main body 41 of the overflow brick 4, so that the main body 41 and the base 2 can be easily aligned, thereby improving assembly efficiency.

[0075] In some embodiments, the base 2 is made of stainless steel.

[0076] In some embodiments, in combination Figure 1 As shown, the reference load-bearing blocks 1 arranged on both sides of the base 2 along the length direction are fixedly connected to the base 2 via fixing members 5 respectively.

[0077] A hole is opened in the middle of the reference load-bearing block 1 , and the reference load-bearing block 1 and the base 2 can be fixedly connected by passing the fixing member 5 through the hole and fastening the fixing member 5 to the base 2 .

[0078] The fixing member 5 may specifically be a bolt.

[0079] In some embodiments, the material of the reference load-bearing block 1 is the same as the material of the overflow brick 4 , and the material of the reference load-bearing block 1 includes zircon.

[0080] By making the material of the reference load-bearing block 1 the same as that of the overflow brick 4 , it can be ensured that it is not easy to be bumped during the hoisting process, and at the same time, scratches on the surface of the overflow brick 4 can be avoided.

[0081] In some embodiments, in combination Figure 3 , Figure 4 As shown, the overflow brick 4 includes a main body 41 and a guide portion 42 disposed on one side of the main body 41, and a surface of the main body 41 facing away from the guide portion 42 is defined as a positioning inclined surface 43;

[0082] The overflow brick processing and installation fixture further includes: an abutting positioning member 23 , which abuts against a positioning inclined surface 43 to align the overflow brick 4 with the base 2 .

[0083] By setting an abutment positioning piece 23 on the side of the base 2 corresponding to the positioning bevel 43, the abutment positioning piece 23 can abut against the positioning bevel 43 to align the overflow brick 4 with the base 2, so that when the overflow brick 4 is hoisted to the overflow brick processing and installation fixture, it can be quickly aligned to improve assembly efficiency.

[0084] In some embodiments, the number of the abutting positioning members 23 is at least two, the positioning planes of at least two abutting positioning members 23 are parallel, and the abutting positioning members 23 are slidably connected to the base 2 .

[0085] By ensuring that the number of the abutting positioning members 23 is at least two, multi-point alignment can be ensured, thereby improving the alignment accuracy between the overflow brick 4 and the base 2 .

[0086] By making the abutment positioning member 23 slidably connected to the base 2, on the one hand, after the overflow brick 4 is aligned with the base 2, the sliding abutment positioning member 23 can be used to verify the assembly position of the overflow brick 4, and on the other hand, the abutment positioning members 23 of different specifications and models can be easily replaced.
