Description

Technical Field

[0001] This utility model relates to the field of industrial quality inspection technology, specifically a special inspection tool for saddle bracket castings. Background Technology

[0002] The saddle bracket is manufactured by casting molten metal. Subsequent processes include deburring, descaling, annealing, normalizing, polishing, and shaping to achieve the final product. Quality inspection is crucial throughout this process to ensure the machining accuracy meets usage requirements. Specifically, a round hole gauge is commonly used for quality inspection of the center hole of the saddle bracket to check its machining accuracy.

[0003] The existing round hole gauge is just a cylindrical inspection pin, which is usually inserted into the center hole by hand for quality inspection. This method can only detect whether the inner diameter of the center hole meets the size and whether it is a perfect circle. It cannot detect the distance between the center hole and the bottom of the saddle support, and the inspection items are limited. Moreover, if the center hole is not a perfect circle, it is impossible to detect the specific location of the non-circular defect in the center hole, and the guidance for improvement is not clear. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a special inspection tool for saddle bracket castings, which can be used to perform quality inspection on various aspects of the saddle bracket, including the shape and size of the holes, the location of shape defects, and the distance from the bottom.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A special inspection tool for saddle bracket castings includes a fixed base. The upper surface of the fixed base is provided with a positioning slot for placing the saddle bracket. A fixed seat is fixed on one side of the fixed base located in the positioning slot. A translation push rod is horizontally movably inserted into the fixed seat. The translation push rod has a hollow structure and a detection push rod is movably inserted inside it.

[0007] One end of the detection push rod is fixed with a round hole gauge corresponding to the position of the hole in the saddle bracket, and the other end is fixed with a detection handle. One end of the translation push rod corresponding to the round hole gauge is fixed with a baffle, and the other end is fixed with a translation handle.

[0008] The circular hole gauge has grooves equidistantly arranged on its circumferential side surface, and a slide bar is slidably connected to the circular hole gauge through the grooves.

[0009] Preferably, the fixed base is provided with fixing holes for installation and fixation.

[0010] Preferably, a sliding sleeve is fixedly embedded in the fixed base, and the fixed base is slidably connected to the translation push rod through the sliding sleeve.

[0011] Preferably, the cross-sections of the translation push rod and the detection push rod are both regular hexagonal structures, and the shapes and dimensions of the sliding sleeve, the translation push rod, and the detection push rod are all compatible.

[0012] Preferably, one end of the round hole gauge corresponding to the positioning slot is threadedly connected to a stop nut, and the sliding groove is located on one side of the stop nut.

[0013] Preferably, the slide bar has a guide slope structure at one end corresponding to the stop nut, the slide groove is equal in length to the slide bar, the slide bar fully covers the circumferential side of the round hole gauge, and the outer side of the slide bar is a smooth curved surface that matches the shape and size of the inner diameter of the standard center hole of the saddle bracket.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention inspects the shape and dimensions of the bottom of the saddle bracket by determining whether it can be inserted into the positioning slot. After the saddle bracket is installed, the distance between the round hole gauge and the upper surface of the fixed base is determined. By judging whether the round hole gauge and the surface slider can be smoothly inserted into the central hole of the saddle bracket, the position of the central hole and its distance from the bottom of the saddle bracket are inspected. If they cannot be smoothly inserted, it indicates that the inner wall of the central hole at the position of the slider that cannot be inserted is not round. In summary, this invention can achieve the effect of multi-faceted quality inspection, facilitates targeted adjustments to the production process, has a positive and clear guiding role, and brings convenience to production.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, this utility model provides a technical solution: a special inspection tool for saddle bracket castings, including a fixed base 1, a fixed mounting hole 102 for installation and fixing, the fixed base 1 can be installed on the inspection table through the fixed mounting hole 102 and bolts, the upper surface of the fixed base 1 is provided with a positioning slot 101 for placing the saddle bracket 2, the positioning slot 101 is made according to the standard size of the saddle bracket 2, when the saddle bracket 2 cannot be smoothly inserted, the surface size is too large or irregular;

[0024] A fixed base 3 is fixed on one side of the positioning slot 101 on the fixed base 1. A translation push rod 4 is horizontally movably inserted into the fixed base 3. A sliding sleeve 10 is fixedly embedded in the fixed base 3. The fixed base 3 is slidably connected to the translation push rod 4 through the sliding sleeve 10. The translation push rod 4 has a hollow structure and a detection push rod 5 is movably inserted inside. The cross-sections of the translation push rod 4 and the detection push rod 5 are both regular hexagonal structures. The shape and size of the sliding sleeve 10, the translation push rod 4 and the detection push rod 5 are all compatible. The vertical distance between the round hole gauge 6 and the upper surface of the fixed base 1, i.e., the height position, is determined by the above structure.

[0025] One end of the detection push rod 5 is fixed with a round hole gauge 6 corresponding to the position of the hole in the saddle bracket 2, and the other end is fixed with a detection handle 7. One end of the translation push rod 4 corresponding to the round hole gauge 6 is fixed with a baffle 8, and the other end is fixed with a translation handle 9. Pushing the translation handle 9 to the left will push the round hole gauge 6 and the slide bar 602 to the left together through the translation push rod 4 and the baffle 8. Pushing the detection handle 7 to the left will only drive the slide bar 602 to the left through the round hole gauge 6. If the slide bar 602 encounters resistance, it will stop moving to the left.

[0026] The circular hole gauge 6 has grooves 601 evenly spaced on its circumferential side. The circular hole gauge 6 is slidably connected to a slide bar 602 through the grooves 601. One end of the circular hole gauge 6 corresponding to the positioning slot 101 is threadedly connected to a stop nut 603. The grooves 601 are located on one side of the stop nut 603. The slide bar 602 is provided with a guide slope structure at one end corresponding to the stop nut 603. The lengths of the grooves 601 and the slide bar 602 are equal. The slide bar 602 fully covers the circumferential side of the circular hole gauge 6, and the outer surface of the slide bar 602 is a smooth curved surface that matches the shape and size of the inner diameter of the standard hole in the saddle bracket 2.

[0027] Working principle:

[0028] During the production process of castings, since subsequent processes such as grinding and polishing are required after casting to reduce dimensions, the external dimensions of the product shall not exceed the external dimensions of the casting, and the internal dimensions of the casting shall not exceed the internal dimensions of the product.

[0029] Install the saddle bracket 2 into the positioning slot 101. If it cannot be installed smoothly, it indicates that the size is too large. The size is too large and needs to be adjusted when it is placed on top of the positioning slot 101 and covering the edge of the positioning slot 101. If it is installed smoothly, the size is acceptable.

[0030] Push the translation push rod 4 to the left by the translation handle 9, and push the round hole gauge and slide bar 602 to the left by the baffle 8. Since the distance between the round hole gauge and the upper surface of the fixed base 1 is determined, if the saddle bracket 2 is held still by hand, the round hole gauge and slide bar 602 will be smoothly inserted into the middle hole, which indicates that the vertical height and front and back position of the middle hole are qualified.

[0031] If the round hole gauge and slide bar 602 cannot be inserted smoothly, push the round hole gauge and slide bar 602 to the left through the detection push rod 5. The slide bar 602 will stop moving to the left due to the obstruction of the inner wall of the central hole. The inner wall of the central hole at the position where the slide bar 602 stops moving to the left is not round and needs to be adjusted. If the gap between the slide bar 602 and the central hole is too large, it indicates that the position of the central hole is offset or that the position is over-ground.
