If the assembly error of the die is within a normal range, namely, the thickness of the die is between the lower limit and the upper limit of the assembly tolerance, the gap is small, and the shadow observed from the side edge is uniform and narrow; if the mold assembly error is too large and the mold thickness is smaller than the lower limit of the assembly tolerance, the gap is relatively large at the moment, and the shadow observed from the side edge is widened and non-uniform, so that the situation that the mold assembly error is too large and the mold needs to be reassembled can be intuitively judged.

Description

Technical Field

[0001] This utility model relates to a vertical special inspection tool that facilitates rapid detection of assembly errors in extrusion dies. Background Technology

[0002] In the manufacturing process of extrusion dies, the assembly accuracy of the die plays a crucial role in the quality of the final product. Currently, the common method for checking die thickness is to use calipers. This method requires manual measurement of different parts of the die one by one, which is cumbersome and inefficient, especially in large-scale production, seriously affecting production progress and efficiency. Moreover, caliper measurement is not a direct indicator of the overall assembly error of the die, and some minor assembly deviations may not be detected in time, leading to inconsistent product quality. Therefore, to address the shortcomings of existing technologies, a vertical special-purpose inspection tool has been developed for rapid detection of assembly errors in extrusion dies. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a vertical, dedicated inspection tool that facilitates rapid detection of assembly errors in extrusion dies.

[0004] In order to achieve the above-mentioned objectives of this utility model, the following technical solution is adopted:

[0005] A vertical special inspection fixture for quick detection of assembly errors in extrusion dies includes a fixture body with an inspection port and inspection surfaces on both sides of the inspection port; a light source recessed into the inspection surface with its top surface aligned with or lower than the top surface of the inspection surface; and bases at both ends of the fixture body, which support the fixture body in a vertical installation.

[0006] Furthermore, the vertical special inspection tool of this utility model, which facilitates rapid detection of assembly errors of extrusion molds, also includes a storage battery, which is installed in the main body of the inspection tool and is used to supply power to the light source.

[0007] Furthermore, the vertical special inspection tool of this utility model for facilitating rapid detection of assembly errors of extrusion molds also includes a battery cover and screws. The top of the main body of the inspection tool has a battery slot with an open top. The top two sides of the battery slot have recessed grooves, and the bottom of the recessed grooves has threaded holes. The battery slot is used to hold a battery. The battery cover has connecting ears at both ends, and the connecting ears have through holes corresponding to the threaded holes. The battery cover is fastened to the top of the battery slot, the connecting ears are inserted into the recessed grooves, and the screws pass through the through holes and are threadedly connected to the threaded holes.

[0008] Furthermore, the light source is a light strip.

[0009] Furthermore, the light strip is an LED light strip.

[0010] Furthermore, the vertical special inspection tool of this utility model for facilitating rapid detection of assembly errors of extrusion molds also includes a marking line. The marking line is set on the main body of the inspection tool and located above the detection port. The gap between the marking line and the detection surface is within the lower limit of the mold assembly tolerance.

[0011] Furthermore, the vertical special inspection tool of this utility model for facilitating rapid detection of assembly errors of extrusion molds also includes an adjustment mechanism. The main body of the inspection tool has an adjustment groove, the light source is installed in the adjustment groove, and one end of the adjustment mechanism passes through the main body of the inspection tool, extends into the adjustment groove and connects with the light source, and is used to adjust the top surface of the light source to be aligned with or lower than the top surface of the inspection surface.

[0012] Furthermore, the adjustment mechanism includes a base plate for supporting and mounting a light source and being slidable along the adjustment groove; a push plate connected to the base plate; and a screw, one end of which is provided with a locking nut and a fixing nut and is rotatably connected to the push plate, and the other end is provided with a handle, the fixing nut being fixedly installed on the fixture body.

[0013] Furthermore, the vertical special inspection tool of this utility model, which facilitates rapid detection of assembly errors of extrusion molds, also includes a bearing seat, and the push plate and the screw are connected through the bearing seat.

[0014] Furthermore, the vertical special inspection tool of this utility model for facilitating rapid detection of assembly errors of extrusion molds also includes magnets, and the light source is connected to the substrate through multiple magnets.

[0015] The present invention represents a significant advancement over the prior art:

[0016] 1. This utility model can significantly improve inspection efficiency. During inspection, the extrusion die is rolled along the ground through the inspection port of the fixture body, and the overall thickness of the extrusion die can be inspected in one go to determine whether it meets the upper limit of the assembly tolerance. This rapid inspection greatly shortens the inspection time of a single die, allowing more die inspection tasks to be processed in the same amount of time, significantly improving the inspection efficiency on the production line, and thus effectively improving the overall production efficiency of die manufacturing.

[0017] 2. The light source on the side of the inspection port of the gauge body of this utility model can illuminate the gap between the extrusion die and the inspection surface from the side. By observing the changes in light and shadow at the gap, the operator can intuitively see the size of the gap between the die and the inspection surface. If the gap is uniform and small, it indicates that the assembly error of the die is within the normal range; if the gap is too large or the light and shadow are uneven, it indicates that the die assembly error is too large. It can intuitively detect the assembly thickness of the extrusion die, which can not only accurately judge the assembly error of the die, but also help the operator quickly locate the problem, so as to make timely adjustments and corrections, effectively improving the stability and reliability of product quality.

[0018] 3. This invention can quickly and accurately detect assembly errors in extrusion dies, making quality control in the production process more efficient and reliable. On the production line, extrusion dies with excessive assembly errors can be identified and rejected in a timely manner, preventing these defective dies from entering subsequent processing or use stages, thereby reducing scrap and rework rates caused by extrusion die quality problems.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments in this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0027] Example 1:

[0028] like Figure 1-4 As shown, this embodiment is a vertical special inspection tool for quick detection of assembly errors in extrusion dies, including a tool body 3, a light source 7, and a base 1. The tool body 3 is provided with an inspection port 36, and inspection surfaces 31 are provided on both sides of the inspection port 36; the light source is recessed and installed on the inspection surface 31, with its top surface aligned with or lower than the top surface of the inspection surface 31; the two ends of the tool body 3 are provided with bases 1, and the two bases support the tool body 3 in a vertical installation.

[0029] The light source is recessed and installed on the detection surface. The top surface of the light source can be aligned with or lower than the top surface of the detection surface to prevent detection errors.

[0030] One structural shape of the main body 3 of the inspection fixture can be an arch structure, which facilitates the rolling of the extrusion mold to be inspected.

[0031] Understandably, the inspection port of the main body of the fixture is an arch-shaped structure made according to the upper limit of the assembly tolerance requirements of the mold. The main body of the fixture stands on the ground, and the inspection port allows the extrusion mold to roll through.

[0032] The two sides of the inspection port are designated as inspection surfaces, and light sources are recessed into these inspection surfaces to ensure that the top surface of the light source is aligned with or lower than the top surface of the inspection surface. This, in turn, ensures that the gap between the inspection surface and the extrusion die is accurate.

[0033] It should be noted that the shape and size of the arch of the inspection port on the main body 3 of the inspection fixture are determined according to the assembly tolerance requirements of the extrusion die to be inspected.

[0034] When the extrusion die is placed at the inspection port, the light source can emit uniform light to illuminate the gap between the die and the inspection fixture.

[0035] It should also be noted that caliper measurement relies on manual operation and reading, which is easily affected by factors such as the operator's skill level, the accuracy of the measuring tool, and visual errors. It may be difficult to accurately detect some minor assembly deviations. Moreover, caliper measurements only provide discrete data and cannot intuitively reflect the overall assembly error of the mold. This utility model, a vertical special inspection fixture for quickly detecting assembly errors in extrusion molds, solves these problems. The inspection port of the fixture body is made into an arch shape according to the upper limit of the mold assembly tolerance requirements. When the mold passes through, it can accurately and quickly determine whether the mold thickness exceeds the tolerance. Specifically, a light source installed on the side of the inspection port of the fixture body can illuminate the gap between the mold and the inspection surface from the side. By observing the changes in light and shadow at the gap, the operator can intuitively see the size of the gap between the mold and the inspection surface. If the gap is uniform and small, it indicates that the mold assembly error is within the normal range; if the gap is too large or the light and shadow are uneven, it indicates that the mold assembly error is too large. This intuitive inspection method can not only accurately determine the assembly error of the mold, but also help operators quickly locate the problem, so as to make timely adjustments and corrections, effectively improving the stability and reliability of product quality.

[0036] In some embodiments, a power supply structure for the light source is provided, in which a storage battery 8 is added. The storage battery 8 is installed in the fixture body 3 and is used to supply power to the light source 7.

[0037] Understandably, the battery supplies power to the light sources installed on both sides of the detection port.

[0038] In some embodiments, a battery mounting structure is provided, which includes a battery cover 6 and screws 5. The top of the fixture body 3 has an open-top battery compartment 33, and recesses 34 are formed on both sides of the top of the battery compartment 33. Threaded holes 35 are formed at the bottom of the recesses 34. The battery compartment 33 is used to hold the battery 8. The battery cover 6 has connecting ears 61 at both ends, and through holes 62 are formed on the connecting ears 61 corresponding to the threaded holes 35. The battery cover 6 is fitted onto the top of the battery compartment 33, the connecting ears 61 are inserted into the recesses 34, and the screws 5 pass through the through holes 62 and are threaded into the threaded holes 35.

[0039] When installing the battery, install the battery in the battery compartment 33 and connect the battery to the light source installed on both sides of the detection port. Then, put the battery cover 6 on the top of the battery compartment 33, and insert the connecting ears 61 on both ends of the battery cover 6 into the recesses 34 on both ends of the top of the battery compartment. When the connecting ears are inserted to the bottom of the recess, screw 5 is threaded through the through hole 62 on the connecting ear 61 and threaded through the threaded hole 35. Tighten the screw 5 to fix the connecting ear in the recess.

[0040] Understandably, when it is necessary to remove the battery cover, the screws on the two connecting lugs can be unscrewed to remove the battery cover.

[0041] The battery cover can close the battery compartment and prevent debris from falling into it.

[0042] In some embodiments, a structure for a light source is provided. The light source is a light strip.

[0043] In this embodiment, the light strip can be an LED light strip. It is understood that an LED light strip is formed by assembling LEDs onto a strip-shaped FPC (flexible printed circuit board) or PCB rigid board. LED light strips can utilize electrical energy more efficiently, generating less heat, thereby reducing energy consumption and negative environmental impact. They also feature safe low voltage, high brightness, and flexibility.

[0044] In some embodiments, a marking line 4 is added to enable faster determination of the width of the light band between the inspection surface and the extrusion die. The marking line 4 is located on the fixture body 3 and above the inspection port 36. The gap between the marking line and the inspection surface 31 is within the lower limit of the mold assembly tolerance.

[0045] It should be noted that the color of the marking line can be a bright color, such as red, green, blue, or yellow.

[0046] The extrusion die is placed at the inspection port, and light from the light source shines onto the extrusion die, creating a bright light and shadow effect in the gap between the extrusion die and the inspection surface. If the width of the light and shadow is within the gap between the marking line and the inspection surface 31, and the light and shadow are uniform, it indicates that the assembly error is within the normal range. If the width of the light and shadow exceeds the marking line or the light and shadow are uneven, it indicates that the assembly error is too large.

[0047] In some embodiments, a structure for adjusting the position of the light source is provided, and an adjustment mechanism 2 is added. The fixture body 3 has an adjustment groove 32, the light source 7 is installed in the adjustment groove 32, and one end of the adjustment mechanism 2 passes through the fixture body 3 and extends into the adjustment groove 32 to connect with the light source 7, for adjusting the top surface of the light source 7 to be aligned with or lower than the top surface of the detection surface 31.

[0048] In some embodiments, a structure for the adjustment mechanism is provided. For example... Figure 3As shown, the adjustment mechanism 2 includes a base plate 21, a push plate 22, and a screw 23. The base plate 21 is used to support and mount the light source 7 and can slide along the adjustment groove 32; the push plate 22 is connected to the base plate 21; one end of the screw 23 is provided with a locking nut 25 and a fixing nut 24 and is rotatably connected to the push plate 22, and the other end is provided with a handle 26. The fixing nut 24 is fixedly mounted on the fixture body 3.

[0049] One rotatable connection structure between the screw and the push plate is as follows: the push plate 22 and the screw 23 are connected through a bearing seat 27. This allows the screw to rotate smoothly.

[0050] It should be noted that when the screw moves to the set position, tighten the locking nut. The locking nut can further lock the screw, preventing it from loosening and thus avoiding the substrate from moving. This allows the substrate to accurately support the light source in the adjustment groove.

[0051] Work style:

[0052] When the position of the light source needs to be moved outward, the screw 23 is turned clockwise by the handle 26. The screw 23 can be screwed in relative to the fixing nut 25. The screw 23 extends into the adjustment groove. The screw pushes the substrate to move to the side of the detection port. The substrate drives the light source to move. When it moves to the set position, stop turning the screw and tighten the locking nut.

[0053] When the position of the light source needs to be moved inward, the screw 23 is turned counterclockwise by the handle 26. The screw 23 can be unscrewed relative to the fixing nut 25. The screw 23 retracts relative to the adjustment groove. The screw pulls the substrate to move away from the detection port. The substrate drives the light source to move. When it moves to the set position, the screw is stopped and the locking nut is tightened.

[0054] In some embodiments, a mounting structure for the light source is provided, in which magnets 9 are added. The light source 7 is connected to the substrate 21 via a plurality of magnets 9.

[0055] One way to connect a magnet and a light source is by bonding them together with glue.

[0056] The number of magnets on the light source can be 2, 3, 4, 5, 6, 7, 8, 9, or 10. The light source can be quickly mounted on the substrate using multiple magnets. Understandably, the substrate can be made of carbon steel, which facilitates rapid attraction by the magnets.

[0057] According to the above embodiments, the working principle of this utility model is as follows:

[0058] The inspection port 36 of the fixture body 3 is an arch-shaped structure made according to the upper limit of the assembly tolerance requirements of the extrusion die. The fixture body 3 stands on the ground, and the assembled extrusion die is placed on one side of the fixture body 3, allowing it to roll along the ground towards the inspection port 36. If the extrusion die can pass smoothly through the inspection port 36 of the fixture body 3, it indicates that the thickness of the die does not exceed the upper limit of the assembly tolerance. At the same time, observe the light and shadow at the gap between the die and the side of the inspection port of the fixture body 3. If the light and shadow are uniform and narrow, it indicates that the thickness of the die is between the lower and upper limits of the assembly tolerance, and the die assembly error is normal. If the die cannot pass through the inspection port of the fixture body 3, or if the light and shadow observed from the side becomes wider and uneven during the passage, it is determined that the die assembly error is too large, and the die needs to be reassembled and adjusted until the die can pass smoothly through the fixture and the light and shadow are normal.

[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
