Description

Technical Field

[0001] This application relates to the field of mold stamping inspection technology, and in particular to a displacement detection structure for automotive mold stamping. Background Technology

[0002] Stamping is a crucial step in automobile manufacturing, using stamping equipment to process sheet metal into body parts. During the stamping process, the motion accuracy of the die directly affects the dimensional accuracy, surface quality, and production efficiency of the parts.

[0003] A search revealed Chinese Patent Publication No. CN212945008U, which discloses a displacement detection structure for automotive mold stamping, belonging to the field of automotive manufacturing technology. The structure includes a lower support platform with integrated sliding grooves at both ends. Receiving platforms are movably connected inside these grooves. A receiving plate and a fixed guide platform are fixedly connected from left to right above the left receiving platform. A power-off alarm and a limit switch are fixedly connected from top to bottom at the front end of the left receiving plate. This invention incorporates a limit switch and a power-off alarm. When the lower mold shifts during stamping, the lower mold will push the telescopic rod backward against the front limit member via a front limit member and a spring. The force on the telescopic rod causes the rear limit member to press against the limit switch. Upon contact, the limit switch will de-energize the entire stamping equipment. The power-off alarm will then be triggered, awaiting operator intervention. This prevents damage or even scrapping of the stamping mold or automotive parts, further improving product quality and work progress.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects in this patent:

[0005] The patent describes a nested installation of the laser positioner in the upper mold, which makes the installation, disassembly, and maintenance of the laser positioner particularly cumbersome and requires the use of external tools.

[0006] Therefore, in response to the above problems, the applicant provides a displacement detection structure for automotive mold stamping. Utility Model Content

[0007] In order to solve the problems mentioned in the background art, this application provides a displacement detection structure for automotive mold stamping.

[0008] This application provides a displacement detection structure for automotive die stamping, which adopts the following technical solution:

[0009] A displacement detection structure for automotive mold stamping includes an upper mold and a light source receiving hole. The upper mold is provided with a disassembly and assembly mechanism with disassembly and assembly functions. The disassembly and assembly mechanism includes a sliding column, a spring and an "I"-shaped slider. The sliding column has a sliding groove, and the "I"-shaped slider is slidably connected to the sliding groove. One side of the "I"-shaped slider is fixedly connected to one side of the spring.

[0010] The light source receiving hole is provided with a splash-proof mechanism, which includes a light path guiding cavity, an acrylic plate and a silicone gasket. A dust filter is embedded in the middle of the light path guiding cavity, and an acrylic plate is attached to the top surface of the light path guiding cavity. The acrylic plate is fitted with a silicone gasket.

[0011] Optionally, it also includes a lower mold, wherein each of the four corners at the bottom of the lower mold is fixedly connected to a support leg, and a bracket is fixedly connected to one side of the lower mold. The top surface of the input end of an electric push rod is vertically fixedly connected to the bracket, and the output end of the electric push rod is fixedly connected to the center of the upper mold.

[0012] Optionally, limit holes are provided at the four corners of the lower mold, and limit posts are fixedly connected at the four corners of the bottom of the upper mold, with the four limit posts correspondingly inserted into the limit holes.

[0013] Optionally, the upper mold has four vertically formed laser locator holes, and each of the four laser locator holes has a limiting groove extending from both sides. Each of the limiting grooves is connected to an "I"-shaped slot.

[0014] Optionally, it also includes four laser positioners, with a laser positioner mounting base fixedly connected to the top surface of each of the four laser positioners. Sliding columns are symmetrically fixedly connected to the outer circumferential wall of the laser positioner mounting base. A spring is fixedly connected to one side of the sliding column. A pull handle is fixedly connected to the top surface of the "I"-shaped slider. The laser positioner and the laser positioner mounting base are inserted into the laser positioner hole. The sliding column is located in the limiting groove. The "I"-shaped slider is inserted into the "I"-shaped slot.

[0015] Optionally, the lower mold has four light source receiving holes, each containing an acrylic plate. The light path guiding cavity is fixedly connected to the edge of the QPD sensor base, and the QPD sensor is located on the bottom surface of the light source receiving hole.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] 1. This utility model, through the setting of the disassembly and assembly mechanism, allows the "I"-shaped slider to move from the "I"-shaped slot to the slide groove by applying force with the handle in the center. Then, the slide groove column can be taken out from the laser positioner hole. The setting of the handle allows the "I"-shaped slider to be quickly inserted into the "I"-shaped slot, thereby quickly positioning the laser positioner in the laser positioner hole. It also has the advantage of being able to quickly complete the assembly and disassembly without tools.

[0018] 2. This utility model, through the setting of the anti-splash mechanism, the acrylic plate and silicone gasket can effectively block liquid contaminants such as coolant, lubricant, and cleaning agent, preventing them from forming an oil film or liquid film on the filter screen surface, thus ensuring laser transmittance. At the same time, the acrylic plate can achieve elastic buffering and absorb the vibration of the stamping machine. The dust filter can be used to intercept metal debris, oxide scale and fibrous contaminants generated during the stamping process, preventing them from depositing on the inner wall of the reflective cavity or the QPD photosensitive surface, reducing positioning deviation caused by particulate contamination.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a displacement detection structure for automotive mold stamping.

[0027] like Figure 1-5 As shown, a displacement detection structure for automotive mold stamping includes an upper mold 104 and a light source receiving hole 9. The upper mold 104 is provided with a disassembly and assembly mechanism with disassembly and assembly functions. The disassembly and assembly mechanism includes a sliding column 5, a spring 6, and an "I"-shaped slider 7. The sliding column 5 has a sliding groove 50, and the "I"-shaped slider 7 is slidably connected to the sliding groove 50. One side of the "I"-shaped slider 7 is fixedly connected to one side of the spring 6.

[0028] The light source receiving hole 9 is provided with a splash-proof mechanism, which includes a light path guiding cavity 11, an acrylic plate 13, and a silicone gasket 14. A dust filter 12 is embedded in the middle of the light path guiding cavity 11, and the top surface of the light path guiding cavity 11 is attached to the acrylic plate 13. The acrylic plate 13 is fitted with a silicone gasket 14.

[0029] Please see Figure 1 The press also includes a lower mold 100, with support legs fixedly connected to the four corners of the bottom of the lower mold 100. A bracket 102 is fixedly connected to one side of the lower mold 100. The top surface of the input end of an electric push rod 103 is vertically fixedly connected to the bracket 102. The output end of the electric push rod 103 is fixedly connected to the center of the upper mold 104. The electric push rod 103 is connected to an external power source. The electric push rod 103 drives the upper mold 104 to press down and fit against the lower mold 100. The lower mold 100, the limiting hole 101, the bracket 102, the electric push rod 103 and the upper mold 104 are combined to form a stamping machine.

[0030] Please see Figure 1 Limiting holes 101 are provided at the four corners of the lower mold 100, and limiting posts 105 are fixedly connected at the four corners of the bottom of the upper mold 104. The four limiting posts 105 are inserted into the limiting holes 101 respectively.

[0031] Please see Figure 3 The upper mold 104 has four vertically formed laser locator holes 2. Each of the four laser locator holes 2 has a limiting groove 3 extending from both sides. Each of the limiting grooves 3 has an "I"-shaped slot 30 connected to both sides. The laser locator holes 2, the limiting grooves 3 and the laser locator 4 are integrally formed slots.

[0032] Please see Figure 3It also includes four laser positioners 4, with laser positioner mounting bases 40 fixedly connected to the top surfaces of the four laser positioners 4. Sliding columns 5 are symmetrically fixedly connected to the outer circumferential wall of the laser positioner mounting bases 40. A spring 6 is fixedly connected to one side of the sliding column 50. A pull handle 8 is fixedly connected to the top surface of the "I"-shaped slider 7. The laser positioners 4 and laser positioner mounting bases 40 are inserted into the laser positioner holes 2. The sliding columns 5 are located in the limiting grooves 3. The "I"-shaped slider 7 is inserted into the "I"-shaped slot 30. The user slides the two handles 8 in the center with one hand, and the spring 6 retracts. The "I"-shaped slider 7 slides in the center of the slide groove 50. At this time, the laser locator 4 is inserted into the laser locator hole 2. The slide groove post 5 is aligned with the limiting groove 3 and lowered. When the handle 8 is released, the spring 6 rebounds and drives the "I"-shaped slider 7 to push to both sides in the slide groove 50. The "I"-shaped slider 7 is inserted into the "I"-shaped slot 30 to fix the laser locator 4.

[0033] Please see Figure 4 The lower mold 100 has four light source receiving holes 9, and an acrylic plate 13 is pressed into each of the four light source receiving holes 9. The optical path guiding cavity 11 is fixedly connected to the edge of the QPD sensor 10 base. The QPD sensor 10 is located on the bottom surface of the light source receiving hole 9. The laser positioner 4 fixed to the upper mold 104 emits a collimated laser beam vertically downward. The QPD sensor 10 fixed to the lower mold 100 is located directly below the laser beam, and the center of its photosensitive surface coincides with the initial position of the laser spot, forming a zero-point reference. When the upper and lower molds are relatively displaced, such as due to mold wear, thermal expansion, mechanical vibration, etc., the relative position of the photosensitive surface of the QPD sensor 10 changes, and the light spot undergoes a two-dimensional shift on the QPD surface, thereby detecting the shift between the upper mold 104 and the lower mold 100.

[0034] The implementation principle of a displacement detection structure for automotive die stamping according to an embodiment of this application is as follows:

[0035] The user slides the two handles 8 in the center with one hand, the spring 6 retracts, and the "I"-shaped slider 7 slides in the center of the slide groove 50. At this time, the laser locator 4 is inserted into the laser locator hole 2, the slide groove post 5 is aligned with the limiting groove 3 and lowered, and the handle 8 is released. The spring 6 rebounds and drives the "I"-shaped slider 7 to push to both sides in the slide groove 50. The "I"-shaped slider 7 is inserted into the "I"-shaped slot 30 to complete the fixation of the laser locator 4.

[0036] When the laser locator 4 needs to be removed, simply hold the handle 8 and apply force in the center to move the "I"-shaped slider 7 from the "I"-shaped slot 30 into the slide groove 50. Then, the slide groove post 5 can be lifted out of the laser locator hole 2. As described above, the handle 8 allows the "I"-shaped slider 7 to be quickly inserted into the "I"-shaped slot 30, thereby quickly positioning the laser locator 4 in the laser locator hole 2. This allows for quick assembly and disassembly without the need for tools.

[0037] The acrylic plate 13 and silicone gasket 14 can effectively block liquid contaminants such as coolant, lubricant, and detergent, preventing them from forming an oil film or liquid film on the filter screen surface, thus ensuring laser transmittance. At the same time, the acrylic plate 13 can provide elastic buffering and absorb the vibration of the stamping machine.

[0038] The dust filter 12 can be used to intercept metal chips, oxide scale and fibrous contaminants generated during the stamping process, preventing them from depositing on the inner wall of the reflective cavity or the QPD photosensitive surface, reducing positioning deviation caused by particulate contamination. The above structure can prevent metal chips from clogging the light source receiving hole 9 during the stamping process, and also has the advantage of preventing liquid and chip splashes.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
