Description

Technical Field

[0001] The utility model relates to the technical field of optical cold processing, in particular to an adjustment fixture for multi-angle and multi-type prism tooling products. Background Art

[0002] At present, the prism angle processing in the optical cold processing industry has a method of directly debugging the product angle using a comparison goniometer. The operation is cumbersome and complicated. For high-precision prism processing with accuracy to """ and "′", the processing efficiency and yield are very low. Generally, a high-precision comparison goniometer is used to debug the angle tooling first and then put the product on the angle tooling. However, when using this indirect method to process the product angle on the tooling, the product and the tooling, and the tooling and the optical plastic disc must fit tightly and be aligned. Otherwise, serious dimensional deviation and angle deviation will occur. Parallel glass plates with very strict surface shape and parallelism requirements are often used to align the right-angled surfaces of the product and the tooling. Using parallel plates to make products requires frequent wiping of the plate surface to ensure cleanliness, which is inefficient. In addition, the tooling cannot be fixed, which easily causes the product to deviate from the position. The more efficient angle flip tooling flat mirror is greatly restricted and cannot be used.

[0003] Therefore, there is still a need for an adjustment fixture for multi-angle and multi-type prism tooling products to solve the above problems. Utility Model Content

[0026] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0027] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0028] Reference Figure 1-6 The utility model provides an adjustment fixture for multi-angle and multi-type prism tooling products, including: a base 1, a vertical block 2, and a horizontal block 3. A vertical groove 11 is provided on one side of the base 1, and a horizontal groove 12 is provided on the top. The vertical block 2 is slidably connected in the vertical groove 11, and can move relative to the base 1 along the vertical groove 11 in the vertical direction. The top of the vertical block 2 is provided with a V-shaped groove 21 for placing the V-shaped block of the tooling. The horizontal block 3 is slidably connected in the horizontal groove 12, and can move relative to the base 1 in the horizontal direction along the horizontal groove 12. A limiting portion is provided on one side of the horizontal block 3 corresponding to the vertical block 2, which is used to abut the product side wall on the top of the tooling from the side. The vertical groove 11 is opened on the base 1 and extends in the vertical direction.

[0029] The workpiece to be processed includes two parts, one of which is the tooling and the other is the workpiece to be processed. The workpiece to be processed needs to maintain a certain angle with the tooling and be hung on a designated fixed plate through the tooling. Then, the excess of the workpiece to be processed is removed by cutting parts to form a high-precision prism. Finally, the tooling and the prism are separated.

[0030] The tooling is an auxiliary plate material, which may be a glass plate. When connecting, the workpiece to be processed and the tooling may be fixed to the surface of the tooling through the optical bonding phenomenon.

[0031] The splicing-type adjustable connection method is adopted. Through simple calculation, the jig can be accurately adjusted to process the product angle to improve the yield, reduce the reserved size length of the product, increase the product yield rate and save costs. It can not only meet the customer's processing needs at different angles, but also reduce the manufacturing cost of tooling and products. It has a simple and clever structure, firm splicing positioning and not easy to separate, and can easily increase or change the position of the slider. It is suitable for tooling production and processing of various types, angles and sizes; after the tooling is adjusted, you only need to record the slider position data to facilitate the data coordinates of different products in subsequent production to quickly adjust the jig, save production time, improve efficiency, and standardize the processing flow. It is safer and more durable. The jig is wear-resistant and corrosion-resistant, and it is not easy to produce glass debris to cause safety risks. The SUS304 steel structure makes the parallel angle not easy to change due to wear and is stable and reliable, which significantly reduces the risks of a wide variety of tooling fixtures, difficult storage, large errors, and easy confusion.

[0032] In one embodiment, fixing plates 4 are respectively disposed on both sides of the base 1 , and the fixing plates 4 are connected to both sides of the base 1 by bolts.

[0033] The fixed splint 4 is provided with strip grooves on both sides close to the vertical block 2, and vertical scales are provided on the outer side walls of the fixed splint 4 on both sides of the strip grooves. The vertical block 2 is provided with reference columns 9 and adjustment studs 5 extending from the strip grooves on both sides.

[0034] A horizontal scale is provided on the top side wall of the fixed clamp plate 4 parallel to the moving direction of the horizontal block 3 , and a notch for aligning with the horizontal scale is provided on the horizontal block 3 .

[0035] In one embodiment, a strip groove is formed on the horizontal block 3, and a screw rod of a positioning bolt is connected inside the strip groove. When the position of the horizontal block 3 is fixed, the bottom of the positioning bolt is connected to the base 1 through a thread to fix the position of the horizontal block 3. When adjusting, the horizontal block 3 is horizontally moved to a specified position, and then the positioning screw rod is screwed to lock the position.

[0036] In one embodiment, a connecting groove 22 is further formed at the bottom of the V-shaped groove 21. The connecting groove 22 is a strip-shaped groove, which is convenient for taking and placing tooling.

[0037] In one embodiment, the reference column 9 is provided with a cross scale mark for correction with the vertical scale, and the starting position of the vertical scale is the position where the top of the vertical block 2 overlaps with the bottom surface of the protruding platform of the horizontal block 3.

[0038] The utility model is suitable for a flip tool with a tooling inner height of 3mm to 16mm and an angle of 0-90°. The height position of the debugging vertical block 2 (i.e. the scale specified by the horizontal arrow of the crosshairs of the slider) = tooling inner height ÷ cos ((tooling large angle - tooling small angle) / 2) - 3mm. The position formula of the special 45° flip tool = tooling inner height - 3mm. The height of the tooling position can be accurately adjusted according to the different tooling inner heights.

[0039] The starting position of the horizontal scale of the fixed splint 4 is the vertical plane position where the midpoint line of the inclined groove of the vertical block 2 is located. By setting it at this position, the horizontal block 3 can be moved left and right to measure the horizontal coordinate position of the center point of the contact surface between the tooling and the product, wherein: the center horizontal coordinate position = the scale value on the left side of the tooling - the scale value on the right side of the tooling > 0, the horizontal block 3 needs to adjust the slider to the left to move to the scale marked by the center position; when the center position is <0, move to the right across the 0 scale line to the scale marked by the center position, and the horizontal block 3 can be moved or fixed by the loose or tight state of the positioning stud 6.

[0040] The final adjustment position of the horizontal block 3 is obtained through the formula = (COS ((tooling large angle - tooling small angle) / 2) * product width) / 2 - (position reading on the left side of the tooling slope surface - reading on the right side) / 2. This calculation method can quickly obtain the position to be adjusted, which is suitable for products with large reserved sizes.

[0041] The adjustment position of the horizontal block 3 = (COS ((tooling large angle - tooling small angle) / 2) * product width) / 2 - tooling bevel length * cos ((tooling large angle - tooling small angle) / 2). This formula is suitable for products with small reserved dimensions and strict requirements such as angle tolerance ± 0.1° and size ± 0.02mm. It improves product yield and yield, improves production efficiency, and standardizes and quantifies the production method of angled products.

[0042] The tooling height mentioned in the above formula is the length from the top of the tooling placed in the V-shaped groove 21 to the bottom of the tooling. Taking the tooling slope of 60 degrees as an example, the tooling large angle is 60 degrees and the tooling small angle is 30 degrees. The product width is the length in the cross section of the product.

[0043] The high-precision adjustment jig can make the flip jig realize the function of the triangular jig, reduce the repeated production of the same angle jig, save costs, and increase the scope of application of the jig. The function of the horizontal block 3 is to determine the position of the product and control it. Combined with the strict control of the jig position by the vertical block 2, the jig can be used for the production and processing of prism precision angle products.

[0044] Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the utility model.
